ATOMIZER AND ELECTRONIC ATOMIZATION DEVICE

CROSS-REFERENCE TO PRIOR APPLICATION

Priority is claimed to Chinese Patent Application No. 202323080536.2, filed on Nov. 15, 2023, the entire disclosure of which is hereby incorporated by reference herein.

FIELD

The present application relates to the field of atomization technologies, and more specifically, to an atomizer and an electronic atomization device.

BACKGROUND

An electronic atomization device is configured to heat an aerosol-forming article to generate an aerosol. Generally, a heating temperature of a heating member of the electronic atomization device is usually higher than 180° C., and a temperature of the aerosol generated by the electronic atomization device through heating is also high and usually higher than 100° C. However, an airflow suitable temperature that can be accepted by the oral cavity of a user is 70° C. or lower. To reduce the temperature of the aerosol, in the related art, generally, the length of an air passage of a suction nozzle is extended, the air passage is widened, or a heat dissipation structure is added in the air passage, which has large influence on an entire structure of the device. In addition, a contact area between the aerosol and the air passage may be further increased. In this process, convection heat transfer occurs between the aerosol and the wall surface of the air passage. As a result, condensate is generated on the wall surface of the air passage while the temperature of the aerosol is reduced, and an amount of the aerosol intercepted in the air passage is increased. That is, an amount of the aerosol inhaled and used by the user is reduced, and generation of the condensate leads to an increase in a quantity of times of cleaning the device by the user.

SUMMARY

In an embodiment, the present invention provides an atomizer, comprising: an aerosol-forming article having formed therein an accommodating cavity configured to accommodate an aerosol-forming substrate; and a suction nozzle assembly engaged with the aerosol-forming article, the suction nozzle assembly comprising an air inlet passage and an air outlet passage respectively in communication with the accommodating cavity and an assistance air passage directly or indirectly communicating the air outlet passage with external air.

FIG. 1 to FIG. 3 show an electronic atomization device 100 according to some embodiments of the present application. The electronic atomization device 100 is configured to heat an aerosol-forming substrate to generate an aerosol for a user to use. Heating manners that may be used by the electronic atomization device 100 include, but are not limited to, one or more of thermal conduction, electromagnetic, infrared radiation, ultrasonic, microwave, plasma, or the like. As used herein, the term “aerosol-forming substrate” refers to a substrate that can release volatile compounds to generate an aerosol after being heated. The aerosol-forming substrate includes, but is not limited to, a material used for medical care, health preservation, health, and cosmetic purposes. The aerosol-forming substrate may include one or more of solid, liquid, paste, or gel.

The electronic atomization device 100 may include an atomizer 10 and a power supply device 20 engaged with the atomizer 10. The atomizer 10 is mainly configured to store the aerosol-forming substrate and atomize the aerosol-forming substrate after heat is generated, and the power supply device 20 is mainly configured to control power supply. The atomizer 10 and the power supply device 20 may be connected together in a detachable manner, and the power supply device 20 may be reused, thereby reducing use costs. Certainly, in other embodiments, the atomizer 10 and the power supply device 20 mat alternatively be connected together in a non-detachable manner.

Specifically, as shown in FIG. 2 and FIG. 3, a receiving cavity 210 is formed at an upper end of the power supply device 20. The atomizer 10 is at least partially accommodated in the receiving cavity 210 and may be coaxially arranged with the power supply device 20, but is not limited to the coaxially arranged manner. The atomizer 10 is pluggably connected to the power supply device 20, and the pluggable disassembly and assembly are very convenient.

In this embodiment, the electronic atomization device 100 heats the aerosol-forming substrate in an electromagnetic induction manner. The power supply device 20 may include a housing 21, and a battery 22, a circuit board 23, and an induction heating source 24 that are accommodated in the housing 21. The circuit board 23 is electrically connected to the battery 22 and the induction heating source 24 respectively. The circuit board 23 is provided with a control chip and a related control circuit, and is configured to implement calculation and control on the device, including being configured to control the battery 22 to power on and power off the induction heating source 24, and being configured to control a magnitude of power provided by the battery 22 to the induction heating source 24. The battery 22 is configured to supply power to electronic elements such as the circuit board 23 and the induction heating source 24. The induction heating source 24 is configured to generate an electromagnetic field after being powered on, to heat a susceptor material located in the electromagnetic field. Generally, the induction heating source 24 includes an induction coil. The induction coil may be arranged around the outside of the receiving cavity 210 and may be coaxially arranged with the receiving cavity 210, but is not limited to the coaxially arranged manner.

In some embodiments, the power supply device 20 may further include a holder 25 at least partially accommodated in the housing 21. The holder 25 is in a shape of a cylinder with an opening at an upper end and is accommodated in an upper portion of the housing 21, and the inner wall surface of the holder defines at least part of the receiving cavity 210. The holder 25 may be completely accommodated in the housing 21, or the upper end of the holder 25 may extend out of the housing 21. The induction coil may be in a shape of a spiral tube and is arranged around the outside of the holder 25.

Further, the power supply device 20 may further include a magnetic shielding member 27 sleeved on the outside of the induction heating source 24. The magnetic shielding member 27 can prevent or reduce electromagnetic radiation from the induction heating source 24 to the outside. In addition, the magnetic shielding member 27 can also fix the induction heating source 24.

In some embodiments, the power supply device 20 may further include at least one magnet 26 configured to be magnetically engaged with the atomizer 10. In this embodiment, there are two magnets 26, and the two magnets 26 are respectively accommodated on two sides of the upper portion of the housing 21.

The atomizer 10 is designed to be engaged with the electrically operated power supply device 20 including the induction heating source 24. The atomizer 10 includes a susceptor material, and the susceptor material may be coupled to the induction heating source 24 and interact with the induction heating source 24. The term “susceptor material” is used to describe a material that can convert electromagnetic energy into heat. When the susceptor material is located in the electromagnetic field, the electromagnetic field may generate an eddy current in the susceptor material, and the eddy current may heat the susceptor material through ohmic or resistive heating, to further heat the aerosol-forming substrate. In a case that the susceptor material includes a ferromagnetic material (for example, iron, nickel, or cobalt), the susceptor material may be further heated due to a hysteresis loss.

The susceptor material may be formed by any material that may be heated inductively enough to cause the aerosol-forming substrate to generate an aerosol. A suitable susceptor material may include one or more of graphite, molybdenum, silicon carbide, stainless steel, niobium, aluminum, nickel, a nickel-containing compound, titanium, a metal material composite, or the like. In some embodiments, the susceptor material includes metal or carbon.

Preferably, the susceptor material may include a ferromagnetic material or be made of a ferromagnetic material. The ferromagnetic material may include ferritic iron, a ferromagnetic alloy (for example, ferromagnetic steel or stainless steel), ferromagnetic particles, or ferrites. In some embodiments, the susceptor material may be made of 400-series stainless steel, for example, stainless steel 410, stainless steel 420, or stainless steel 430.

As shown in FIG. 2 to FIG. 6, the atomizer 10 may include a suction nozzle assembly 11 and an aerosol-forming article 19 engaged with the suction nozzle assembly. The aerosol-forming article 19 is configured to accommodate and heat an aerosol-forming substrate, and the suction nozzle assembly 11 is configured to output an aerosol generated after the aerosol-forming substrate is atomized to the outside for a user to smoke or inhale.

Specifically, the aerosol-forming article 19 includes a container 16 and a heating member 17. The container 16 is in a shape of a cylinder with an opening at an end, and an accommodating cavity 160 configured to accommodate the aerosol-forming substrate is formed in the container. The heating member 17 includes the susceptor material or is made of the susceptor material, and is configured to heat the aerosol-forming substrate after heat is generated. During use, the atomizer 10 is engaged with the power supply device 20, so that the heating member 17 is located in the electromagnetic field generated by the induction heating source 24. The heating member 17 may be coaxially arranged with the induction heating source 24, but is not limited to the coaxially arranged manner. It may be understood that, in other embodiments, the aerosol-forming article 19 may alternatively not include the heating member 17. For example, the susceptor material may be alternatively arranged in the container 16 or the aerosol-forming substrate.

The container 16 may be made of one or more high-temperature resistant materials such as glass, ceramic, metal, plastic, aluminum foil paper, or the like. In this embodiment, the container 16 is in a shape of a cylinder and may be made of a glass material. The glass material has advantages of high temperature resistance, ease to clean, no pollution, no odor, and low costs.

The heating member 17 may be arranged in the container 16. On one hand, the heating member 17 can be in direct contact with the aerosol-forming substrate, and heat generated by the heating member 17 can be directly transferred to the aerosol-forming substrate, thereby improving the heat transfer efficiency. On the other hand, the container 16 can perform a heat insulation function to reduce heat transferred to the outside by the heating member 17. Certainly, in other embodiments, the heating member 17 may alternatively be arranged outside the container 16, or the heating member 17 may alternatively be at least partially embedded on the container 16 to form an integral structure with the container 16.

In some embodiments, the heating member 17 may be arranged in the container 16 in a detachable manner, so that both the heating member 17 and the container 16 can be used as disposable consumables and can be separately replaced, thereby avoiding a cleaning problem and bringing low replacement costs. Certainly, in some other embodiments, the heating member 17 may alternatively be arranged in the container 16 in a non-detachable manner. It should be noted that, non-detachable means that the container 16 or the heating member 17 cannot be detached without being damaged for forced replacement.

The shape of the heating member 17 is not limited. For example, the heating member be in various shapes such as a sheet shape, a tube shape, a cylinder shape, or a spiral shape. In this embodiment, the heating member 17 is in a shape of a cylinder with an opening at an upper end. The cylindrical heating member 17 may also be configured to accommodate the aerosol-forming substrate.

In some embodiments, the aerosol-forming article 19 may further include a limiting member 18 arranged in the container 16, to limit the heating member 17 in the container 16. The limiting member 18 may be made of a high-temperature resistant material such as metal or non-metal. Preferably, the limiting member 18 may be made of a non-ferromagnetic metal material, to prevent the limiting member 18 from dry heating. In addition, the metal material has advantages of high temperature resistance, no pollution, no odor, and low costs.

Specifically, the limiting member 18 may include a sheet-like body 181, and a plurality of airflow through holes 1810 for an airflow to pass through are provided on the sheet-like body 181. The sheet-like body 181 may abut against the upper end of the heating member 17, thereby abutting the heating member 17 against the bottom wall of the container 16. When the aerosol-forming substrate is heated, the sheet-like body 181 further helps to reduce or prevent outward sputtering of the aerosol-forming substrate.

In some embodiments, the outer diameter of the sheet-like body 181 is smaller than the inner diameter of the container 16. The limiting member 18 further includes at least two limiting arms 182 arranged at an outer periphery of the sheet-like body 181, and the limiting member 18 is in contact with the container 16 through the at least two limiting arms 182 to play a limiting function. Preferably, the at least two limiting arms 182 are elastic arms and are arranged at an even interval in a circumferential direction of the sheet-like body 181, so that the at least two limiting arm can be uniform forced and elastically abut against the inner wall surface of the container 16 through an elastic force. A lower end of each limiting arm 182 is connected to the sheet-like body 181, and an upper end is opened outward by a specific angle to elastically abut against the inner wall surface of the container 16.

Certainly, in other embodiments, the limiting member 18 may alternatively not include the limiting arms 182. For example, at least part of the outer peripheral surface of the sheet-like body 181 extends outward to form several convex hulls, and the several convex hulls abut against the inner wall surface of the container 16 to play a limiting function.

It may be understood that, in some other embodiments, the aerosol-forming article 19 may alternatively not include the limiting member 18, and the heating member 17 is limited in the container 16 in another manner. For example, a convex limiting portion may be arranged on the inner wall surface of the container 16 or the outer wall surface of the heating member 17, and the contact between the heating member 17 and the container 16 is limited by the limiting portion.

As shown in FIG. 4 to FIG. 6, the suction nozzle assembly 11 includes an air inlet passage 110a, an air outlet passage 110b, and an assistance air passage 110c. The air inlet passage 110a and the air outlet passage 110b are respectively in communication with the accommodating cavity 160. External air may enter the accommodating cavity 160 through the air inlet passage 110a, and then carry the aerosol generated by atomization of the aerosol-forming substrate in the accommodating cavity 160 out through the air outlet passage 110b. The assistance air passage 110c directly communicates the air outlet passage 110b with the external air, or the assistance air passage 110c communicates the air outlet passage 110b with the air inlet passage 110a to further be in communication with the external air, so that during inhalation, external normal-temperature air can enter the air outlet passage 110b through the assistance air passage 110c, to achieve the purpose of temperature reduction.

The air outlet passage 110b includes an inhalation passage 113b. The inhalation passage 113b may extend downward from the upper end surface of the suction nozzle assembly 11, and a user performs inhalation through the inhalation passage 113b. In some embodiments, a cross-sectional shape of an upper portion of the suction nozzle assembly 11 may have a flat shape such as an ellipse-like shape or an athletic track-like shape. That is, the length dimension of the cross-sectional shape of the suction nozzle assembly 11 is greater than the width dimension thereof. In this way, it may be convenient for the user to perform inhalation by using the mouth. Certainly, in other embodiments, the cross-sectional shape of the upper portion of the suction nozzle assembly 11 may alternatively be another shape such as a circle.

In some embodiments, the suction nozzle assembly 11 may include a suction nozzle 12 and a sealing member 13 at least partially arranged between the container 16 and the suction nozzle 12. Specifically, the bottom surface of the suction nozzle 12 may extend upward to form an accommodating hole 120, a top end of the accommodating hole 120 includes a blocking wall 121, the blocking wall 121 separates the accommodating hole 120 from the inhalation passage 113b, and the sealing member 13 is accommodated in the accommodating hole 120 and may abut against the blocking wall 121. The suction nozzle 12 and the sealing member 13 are separately formed, so that an air passage structure is formed on the suction nozzle 12 and the sealing member 13.

In some embodiments, the sealing member 13 may be made of an elastic material such as silicone. On one hand, the sealing member 13 made of the elastic material has good sealing performance; and on the other hand, the elastic performance of the sealing member 13 can make the pluggable disassembly and assembly of the container 16 very convenient. The suction nozzle 12 may be made of a hard material such as plastic, so that the suction nozzle assembly 11 has a specific structural strength. Certainly, in other embodiments, materials of the suction nozzle 12 and the sealing member 13 may not be limited. For example, the sealing member 13 may alternatively be made of another material such as high-temperature resistant plastic.

In some other embodiments, the sealing member 13 may alternatively be integrally formed with the suction nozzle 12 in a manner such as 3D printing or the like. The integrally formed means that the sealing member 13 and the suction nozzle 12 form an integral structure, and the integral structure combines features of the sealing member 13 and the suction nozzle 12. In other words, the sealing member 13 may alternatively be omitted, and relevant features of the sealing member 13 may be formed on the suction nozzle 12.

In some embodiments, the suction nozzle assembly 11 may further include a fixing member 14 sleeved on the suction nozzle 12. The fixing member 14 is ring-shaped and is sleeved on the bottom portion of the suction nozzle 12, and may be made of a metal material. During temperature changes, the metal material has few thermal expansion and cold contraction deformation, so that fixation between the components of the atomizer 10 is more stable and reliable, bringing better sealing performance. In addition, the fixing member 14 of the metal material may be further configured to be magnetically connected to the power supply device 20.

In some embodiments, the atomizer 10 may further include a vent tube 15, where one end of the vent tube 15 may be embedded in the suction nozzle 12 or the sealing member 13, and the other end of the vent tube may extend into the accommodating cavity 160. The inner wall surface of the vent tube 15 defines a central air passage 150, and an edge air passage 151 is defined between the outer wall surface of the vent tube 15 and the inner wall surface of the container 16. Generally, the edge air passage 151 may be ring-shaped and may be coaxially provided with the central air passage 150. Both the central air passage 150 and the edge air passage 151 are in communication with the accommodating cavity 160. One of the central air passage 150 and the edge air passage 151 may be configured for air intaking and the other is configured for air discharging.

In some embodiments, the air inlet passage 110a may include at least one air inlet hole 111a in communication with the external air, a central air passage 150 in communication with the accommodating cavity 160, and at least one leading-in passage 112a connecting the at least one air inlet hole 111a with the central air passage 150.

The air inlet hole 111a is formed on the suction nozzle 12, and may be formed by the outer wall surface of the suction nozzle 12 through recessing. In this embodiment, there are two air inlet holes 111a which are respectively symmetrically provided on two sides of the side wall of the suction nozzle 12 in a length direction. Certainly, in other embodiments, the two air inlet holes 111a may alternatively be provided on two sides of the side wall of the suction nozzle 12 in a width direction. In some other embodiments, there may be one or more air inlet holes 111a.

The leading-in passage 112a is formed between the suction nozzle 12 and the sealing member 13, and may be formed by the suction nozzle 12 and/or the sealing member 13 through recessing. In this embodiment, there are also two leading-in passages 112a which are formed by the outer wall surface of the sealing member 13 through recessing. One ends of the two leading-in passages 112a are respectively in communication with the two air inlet holes 111a, and the other ends are in communication with the central air passage 150.

Specifically, an insertion hole 133 for insertion of the vent tube 15 is formed through the sealing member 13 in an axial direction, two air guide grooves 131 are respectively formed on the outer wall surface on two sides of the sealing member 13 through recessing, and two air guide grooves 132 respectively communicating the two air guide grooves 131 with the insertion hole 133 are respectively formed on the top surface of the sealing member 13 through recessing. The air guide groove 131 extends in a vertical direction, and an extension direction of the air guide groove may be parallel to the axial direction of the sealing member 13. However, this application is not limited to the parallel relationship. A lower end of the air guide groove 131 is in communication with the air inlet hole 111a, and an upper end is in communication with the air guide groove 132. One end of the air guide groove 132 is in communication with the upper end of the air guide groove 131, and the other end extends in a transverse direction to be in communication with the insertion hole 133.

When the sealing member 13 is mounted in the suction nozzle 12, the suction nozzle 12 plays a covering and sealing function on an opening of the air guide groove 131 and an opening of the air guide groove 132. The air guide groove 131 is covered by the cavity wall surface of the accommodating hole 120 to form an air guide section 1121 of the leading-in passage 112a, the air guide groove 132 is covered by the blocking wall 121 to form an air guide section 1122 of the leading-in passage 112a, and the air guide section 1121 and the air guide section 1122 are in communication with each other to form the leading-in passage 112a.

The air outlet passage 110b may include at least one leading-out passage 111b formed on the sealing member 13 and in communication with the accommodating cavity 160, an inhalation passage 113b formed on the suction nozzle 12, and at least one communication passage 112b communicating the at least one leading-out passage 111b with the inhalation passage 113b.

Specifically, in this embodiment, the inhalation passage 113b extends downward from the top surface of the suction nozzle 12 and may be coaxially provided with the suction nozzle 12. The leading-out passage 111b may be formed by the top surface of the sealing member 13 through recessing downward, and the communication passage 112b may be formed by the bottom surface of the blocking wall 121 through recessing upward. There are two leading-out passages 111b and two communication passages 112b respectively. Lower ends of the two leading-out passages 111b are in communication with the edge air passage 151, and upper ends of the two leading-out passages 111b are respectively in communication with lower ends of the two communication passages 112b. The two leading-out passages 111b and the two communication passages 112b may both be provided symmetrically in a width direction of the suction nozzle assembly 11 respectively. Certainly, in other embodiments, the two leading-out passages 111b and the two communication passages 112b may alternatively be provided symmetrically in a length direction of the suction nozzle assembly 11 respectively. In some other embodiments, there may be one or more leading-out passages 111b and/or communication passages 112b.

The assistance air passage 110c may be formed on the suction nozzle 12, and may extend inward from the outer surface of the suction nozzle 12. As shown in FIG. 5, in this embodiment, there are two assistance air passages 110c, and the two assistance air passages 110c respectively extend laterally and inward from the outer surface on two sides of the suction nozzle 12 in the length direction to be in communication with the inhalation passage 113b.

In the embodiment shown in FIG. 7, there are also two assistance air passages 110c formed on the suction nozzle 12, and the two assistance air passages 110c respectively extend laterally and inward from the outer surface on two sides of the suction nozzle 12 in the width direction and are respectively in communication with the two communication passages 112b.

In the foregoing embodiments, the assistance air passage 110c communicates the air outlet passage 110b with the external air, during inhalation, external normal-temperature air can enter the air outlet passage 110b through the assistance air passage 110c, a high-temperature aerosol in the air outlet passage 110b is mixed with the external normal-temperature airflow, and a temperature of the airflow is reduced after the cold and hot airflows are mixed, thereby reducing a temperature of the aerosol and improving a taste. Through actual measurement, it can be ensured that the temperature of the aerosol in two consecutive heating cycles is lower than 70° C. In addition, the external normal-temperature airflow is introduced into the air outlet passage 110b. When an air outlet amount is unchanged, an original air inlet amount is reduced, and an airflow blown onto the heating member 17 through the air inlet passage 110a is reduced, which effectively reduces a heat loss of the heating member 17, so that a fluctuation of a maintained temperature of the heating member 17 is reduced. However, since the assistance air passage 110c in the foregoing embodiment is implemented by punching the side wall of the suction nozzle 12, the assistance air passage 110c is not hidden. As a result, the assistance air passage may be covered by lips of a user during use, which may cause increased airflow noise.

As shown in FIG. 8 to FIG. 16, in this embodiment, the assistance air passage 110c is hidden in the suction nozzle assembly 11 and communicates the air outlet passage 110b with the air inlet passage 110a, to achieve airflow dividing and temperature reduction purposes, which is conducive to control the airflow noise. By adjusting the cross-sectional area of each air passage, the temperature of the aerosol in the air outlet passage 110b can be reduced by about 30° C., thereby ensuring that the temperature of the aerosol is lower than 70° C. and improving a taste.

In some embodiments, the assistance air passage 110c may be formed between the suction nozzle 12 and the sealing member 13. That is, the suction nozzle 12 and the sealing member 13 jointly define boundary surfaces of the assistance air passage 110c. Generally, the assistance air passage 110c may be implemented by grooving the suction nozzle 12 and/or the sealing member 13.

In some other embodiments, the assistance air passage 110c may alternatively be implemented by punching the suction nozzle 12 or the sealing member 13. That is, the suction nozzle 12 or the sealing member 13 defines all the boundary surfaces of the assistance air passage 110c.

As shown in FIG. 8 to FIG. 10, a groove 122 is formed on the inner surface of the suction nozzle 12 through recessing, and the groove 122 is covered by the sealing member 13 to form the assistance air passage 110c. Specifically, the groove 122 may be formed by the bottom surface of the blocking wall 121 through recessing, and two ends of the groove 122 may be respectively in communicate with two communication passages 112b on two sides of the blocking wall 121. When the sealing member 13 is accommodated in the accommodating hole 120 and abuts against the blocking wall 121, the top surface of the sealing member 13 plays a covering and sealing function on an opening of the groove 122, so that the groove 122 forms the assistance air passage 110c. The assistance air passage 110c is in communication with the insertion hole 133 on the sealing member 13, and is further in communication with the central air passage 150 or the air guide section 1122.

A shape and a quantity of the grooves 122 are not limited. The shape of the groove 122 may include various shapes such as a straight line, a broken line, and an arc. In the embodiments shown in FIG. 8 and FIG. 9, there are two grooves 122 which are in a shape of a straight line. The two grooves 122 may be located on the same straight line. One end (an air inlet end) of each groove 122 is in communication with the central air passage 150, and the other end (an air outlet end) is in communication with the communication passage 112b. Certainly, in other embodiments, the two grooves 122 may alternatively not be located on the same straight line. In addition, the air inlet end of the groove 122 may alternatively be in communication with the air guide section 1122. In the embodiment shown in FIG. 10, the groove 122 is in a shape of a circular arc and communicates the communication passage 112b with the air guide section 1122. The groove 122 may be provided around the outside of the central air passage 150 and may be coaxially provided with the central air passage 150, but is not limited to the coaxially provided manner.

As shown in FIG. 11, in this embodiment, the assistance air passage 110c is provided on and penetrates the blocking wall 121 in a longitudinal direction. That is, the blocking wall 121 defines all the boundary surfaces of the assistance air passage 110c. There may be one or more assistance air passages 110c. Specifically, in this embodiment, there are two assistance air passages 110c, lower ends of the two assistance air passages 110c are respectively in communication with the air guide sections 1122 of the two leading-in passages 112a, and upper ends of the two assistance air passages 110c are in communication with the inhalation passage 113b.

As shown in FIG. 12 to FIG. 16, a groove 134 is formed on the upper end surface of the sealing member 13 through recessing, and the groove 134 is covered by the blocking wall 121 to form the assistance air passage 110c. A shape and a quantity of the grooves 134 are not limited. The shape of the groove 134 may include various shapes such as a straight line, a broken line, and an arc.

In the embodiments shown in FIG. 12 and FIG. 13, there are two grooves 134 which are in a shape of a straight line. The two grooves 134 may be located on the same straight line. One end (an air inlet end) of each groove 134 is in communication with the insertion hole 133, and the other end (an air outlet end) is in communication with the leading-out passage 111b. Certainly, in other embodiments, the two grooves 134 may alternatively not be located on the same straight line. In addition, the air inlet end of the groove 134 may alternatively be in communication with the air guide section 1122.

In the embodiment shown in FIG. 14, the groove 134 is in a shape of a circular arc and communicates the leading-out passage 111b with the air guide groove 132. The groove 134 may be provided around the outside of the insertion hole 133 and may be coaxially provided with the insertion hole 133, but is not limited to the coaxially provided manner.

In the embodiments shown in FIG. 15 and FIG. 16, the groove 134 is formed by the outer surface of the upper end of the sealing member 13 in a radial direction through recessing. Specifically, there may be two grooves 134, and the two grooves 134 may be fan-shaped and may be provided in a rotationally symmetric manner with respect to a central axis of the sealing member 13. One side of each groove 134 is in communication with the leading-out passage 111b, and the other side is in communication with the air guide groove 132.
