Description

FIELD AND BACKGROUND OF THE INVENTION

The present disclosure relates to the field of electronic cigarette technologies, and in particular, to an atomization device of an electronic cigarette and an electronic cigarette.

In recent years, with the gradual improvement of people's living standards, their attention to physical health has generally increased, and more and more people have begun to realize the harm of tobacco to their bodies. As a result, the number of electronic cigarette smokers is increasing rapidly. Electronic cigarettes are electronic products that simulate cigarettes, with a similar appearance, smoke, taste, and feel to cigarettes. In electronic cigarette products, atomization of an electronic liquid is used to provide smokers with inhalable smoke. Compared to real cigarette products, one advantage of electronic cigarettes is that the health hazards to smokers are significantly reduced. And most electronic cigarettes are easy to operate, have a beautiful appearance, and are convenient to carry. Electronic cigarettes generally include power supply components and atomizers. The atomizers are powered by the power supply components, and the electronic liquid is heated and atomized by the atomizers to form smoke for smokers to inhale.

There are many problems with electronic cigarettes in the existing art. For example, when a smoker is inhaling an electronic cigarette, external air flows into an atomization chamber through a lower cover, mixes with an aerosol in the atomization chamber, and the mixed gas is inhaled by the smoker. The existing electronic cigarettes have the drawback of poor mixing of air and the aerosol, which affects the smoker's sensory experience. Moreover, when a smoker is inhaling an electronic cigarette, external airflow entering the electronic cigarette can easily produce noticeable noise, leading to a decrease in smoker's experience. In addition, there is a possibility of a liquid matrix and a condensate inside the electronic cigarette overflowing from an air inlet and a smoke outlet. If the overflow amount is too large, it will seriously affect the smoker's experience.

In view of this, it is necessary to propose a new technical solution to at least solve one of the above-mentioned technical problems.

It should be noted that similar reference numerals and letters indicate similar items in the following figures. Therefore, once an item is defined in one figure, it does not need to be further explained in subsequent figures.

Referring to FIG. 1-FIG. 5, an atomization device of an electronic cigarette according to an embodiment of the present disclosure includes a housing 1, an atomization core assembly 2, a lower cover 3, and an intake distribution plate 4. An atomization chamber 101 and an exhaust channel 102 are formed in the housing and are in communication with each other. An inhalation port 100 is arranged at one end of the housing 1 and is in communication with the exhaust channel 102, and the other end of the housing 1 is an open end. The atomization core assembly 2 is arranged in the housing 1. The lower cover 3 is covered on the open end of the housing 1, and an intake channel 31 is formed in the lower cover 3. Distribution hole 41 are formed in the intake distribution plate 4, and the intake channel 31 is in communication with the atomization chamber 101 through the distribution holes 41. The intake distribution plate 4 is connected to an inner side of the lower cover 3 and abutted against the intake channel 31 to prevent liquid leakage from the atomization chamber.

The atomization device of an electronic cigarette according to the embodiment of the present disclosure mainly includes a housing 1, an atomization core assembly 2, and a lower cover 3. The housing 1 has a storage space, in which an atomization chamber 101, an exhaust channel 102, and a liquid storage chamber 103 are arranged. Wherein, a liquid matrix, such as electronic liquid, is contained in the liquid storage chamber 103. The atomization core assembly 2 can be arranged in the storage space, and includes an atomization core 20, and the atomization core 20 can atomize the electronic liquid in the liquid storage chamber 103 to form the aerosol in the atomization chamber 101. For example, the atomization core 20 can include a porous body and a heating element arranged on the porous body. The porous body may include a liquid suctioning surface and an atomization surface. Wherein the liquid suctioning surface may be in communication with the liquid storage chamber 103, and the atomization surface may be in communication with the atomization chamber 101. The liquid matrix, such as electronic liquid can be accommodated in the liquid storage chamber 103. The electronic liquid in the liquid storage chamber 103 can be guided into the porous body through the liquid suctioning surface and can flow to the atomization surface under the capillary action of the porous body. The heating element is arranged on the atomization surface and can be connected to an electrical connector, so that heat is generated when the heating element is powered on, thereby the electronic liquid near the atomization surface can be heated to form the aerosol.

In short, a working principle of the atomization device of an electronic cigarette according to the embodiment of the present disclosure is that: the electronic liquid stored in the liquid storage chamber 103 of the electronic cigarette continuously permeates through the liquid suctioning surface of the porous body, and the electronic liquid is sucked by the liquid suctioning surface and transferred to the atomization surface. When an smoker inhales the atomization device of an electronic cigarette, a sensor inside is triggered, so that a signal that activates the heating element on the atomization surface to heat the electronic liquid is sent to produce aerosol. The electronic liquid is heated and atomized in the atomization chamber 101, and the external airflow enters through the intake channel 31 of the lower cover 3, and the smoke in the atomization chamber 101 is carried through the exhaust channel 102 and finally enters the smoker's mouth through the inhalation port 100.

In the atomization device of an electronic cigarette according to the embodiment of the present disclosure, firstly, the intake distribution plate 4 is arranged so that the distribution holes 41 on the intake distribution plate 4 can play a role of evenly dispersing and buffering the airflow. In case that the external air flows from the intake channel 31 to the distribution holes 41 in the intake distribution plate 4, a pressure of the external air wll not suddenly change. The distribution holes 41 can ensure both the smoothness of the airflow and the uniformity of airflow distribution, thereby stabilizing the size and direction of airflow. Therefore, the airflow can be moved at a relatively gentle speed, reducing collision and vibration, thereby reducing the airflow noise caused by a smoker when inhaling the electronic cigarette. In addition, the intake distribution plate 4 is connected to the inner side of the lower cover 3 and abutted against the intake channel 31 of the lower cover 3, so that the liquid (such as the electronic liquid or the condensate liquid) produced by the electronic cigarette is prevented from leaking from the intake channel 31 to a certain extent, and improve the smoker's experience.

Referring to FIG. 1-FIG. 5, in an embodiment, locating posts 32 are arranged at the lower cover 3, and locating holes 42 are formed in the intake distribution plate 4. The locating posts 32 can be inserted into the locating holes 42, so that the intake distribution plate 4 can be detachably connected to the lower cover 3.

In this specific example, when the intake distribution plate 4 is installed, the locating posts 32 arranged on the lower cover 3 can be inserted into the locating holes 42 in the intake distribution plate 4. Such connection is simple and easy to operate. Furthermore, in case that the intake distribution plate 4 is damaged, it is also very convenient to remove the damaged intake distribution plate 4 from the lower cover 3 for replacement. Moreover, such connection improves the stability of the intake distribution plate 4 on the lower cover 3, and ensures a sealing effect of the intake distribution plate 4 on the intake channel 31.

Referring to FIG. 1-FIG. 5, in an embodiment, the intake channel 31 includes an air inlet 300 in communication with the outside and an air outlet 301 in communication with the atomization chamber 101. Multiple locating posts 32 are arranged on the lower cover 3 and distributed around the air outlet 301. The locating holes 42 are formed at corresponding positions in the intake distribution plate 4.

In this specific example, the intake distribution plate 4 is connected to the lower cover 3 at multiple locations, so that the stability of the intake distribution plate 4 on the lower cover 3 is further improved and the sealing effect of the intake distribution plate 4 on the intake channel 31 is ensured.

In an embodiment, the intake distribution plate 4 and the lower cover 3 are positioned through embedding of concave and convex structures.

In this embodiment, the intake distribution plate 4 and the lower cover 3 are positioned through embedding of the concave the convex structure, so that the tightness of the connection between the intake distribution plate 4 and the lower cover 3 can be improved, and the leakage of liquid generated in the electronic cigarette from the intake channel 31 can be further avoided.

In a specific example, a locating groove is formed at a surface, facing the lower cover 3, of the intake distribution plate 4. A boss portion is formed around a periphery of the intake channel 31 at the lower cover 3. The boss portion is embedded into the locating groove to connect the intake distribution plate 4 with the periphery of the intake channel 31.

In this specific example, the boss portion at the periphery of the intake channel 31 at the lower cover 3 is embedded into the locating groove in the intake distribution plate 4 and the lower cover 3, so that the intake distribution plate 4 and the lower cover 3 are positioned through embedding of concave and convex structures. In this way, the tightness of the connection between the intake distribution plate 4 and a peripheral of the intake channel 31 can be further improved, and the leakage of liquid produced in the electronic cigarette from the intake channel 31 can be further avoided.

In an embodiment, the intake distribution plate 4 is in a sealed connection with the periphery of the intake channel 31.

In this specific example, the intake distribution plate 4 is in a sealed connection with the periphery of the intake channel 31, that is, a surface of the intake distribution plate 4 is in a sealed contact with an end surface of the intake channel 31, so that the intake distribution plate 4 plays a certain seal role on the intake channel 31, and thereby it is ensured that the leakage of liquid produced in the electronic cigarette from the intake channel 31 will not happen.

In an embodiment, a plug-in tube is arranged at a surface, facing the lower cover 3, of the intake distribution plate 4, the plug-in tube matches the intake channel 31 in shape and size, and the plug-in tube is inserted into the intake channel 31.

In this specific example, the plug-in tube arranged on the intake distribution plate 4 matches the intake channel 31 and is plugged into the intake channel, so that the sealing effect of the intake distribution plate 4 on the intake channel 31 can be further improved.

Referring to FIG. 1-FIG. 5, in an embodiment, the atomization device of an electronic cigarette further includes a bracket 5, the bracket 5 is connected between the exhaust channel 102 and the atomization core assembly 2, and the bracket 5 is in sealed connection with an inner wall of the housing 1. A flow channel 51 is formed in the bracket 5, a first end of the flow channel 51 is connected to the exhaust channel 102, and a second end of the flow channel 51 is connected to the atomization chamber 101. A central axis of the flow channel 51 is offset towards one side of the housing 1 in a width direction of the housing 1 relative to a central axis of the exhaust channel 102.

In the atomization device of the electronic cigarette according to the embodiment of the disclosure, an inhalation port 100 is arranged at one end of the housing 1, and the inhalation port 100 is in communication with the exhaust channel 102. The other end of the housing 1 is an open end. That is, the exhaust channel 102 extends roughly in a direction from the open end to the position where the inhalation port 100 is located. The lower cover 3 is arranged at the open end and connected to the housing 1. The open end can be closed by the lower cover 3. An atomization chamber 101 is formed between the lower cover 3 and the atomization core assembly 2. An intake channel 31 is arranged in the lower cover 3. When the smoker inhales, the outside air can enter the intake channel 31, and the air in the intake channel 31 can flow to the atomization chamber 101. At this time, the air can be mixed with the aerosol in the atomization chamber 101, and the mixed gas can enter the exhaust channel 102, and finally enter the smoker's mouth through the inhalation port 100 in communication with the exhaust channel 102.

It should be noted that the bracket 5 is connected between the exhaust channel 102 and the atomization chamber 101, and the flow channel 51 that connects the atomization chamber 101 and the exhaust channel 102 is formed in the bracket 5, so that the gas generated by mixing air with aerosol (hereinafter referred to as the mixed gas) first passes through the flow channel 51 and then enter the exhaust channel 102. The flow channel 51 is not vertically arranged, but rather the central axis of the flow channel 51 is offset relative to the central axis of the exhaust channel 102, so that the flow path of the above mixed gas can be extended by the flow channel 51. Therefore, a certain buffering effect on the rise of the mixed gas is achieved, so that the mixed gas is avoided from directly colliding the smoker's mouth and have an excessive stimulation to the mouth, thereby the inhalation experience can be improved.

Referring to FIG. 1-FIG. 5, in an embodiment, the intake channel 31 includes an air inlet 300 in communication with the outside and an air outlet 301 in communication with the atomization chamber 101, and the air outlet 301 is offset towards the other side of the housing 1 in the width direction of the housing 1 relative to the air inlet 300.

In this specific example, the air inlet 300 is arranged at a side, close to the outside, of the lower cover 3, and an air outlet 301 is arranged at a side of, close to the atomization core assembly 2, of the lower cover 3. The air inlet 300 and the air outlet 301 are both in communication with the intake channel 31. When the smoker inhales, the external air can enter the intake channel 31 through the air inlet 300, and the air in the intake channel 31 can flow to the atomization chamber 101 through the air outlet 301. At this time, the air can be mixed with the aerosol in the atomization chamber 101. The mixed gas can enter the exhaust channel 102, and finally enter the smoker's mouth through the inhalation port 100 in communication with the exhaust channel 102. The air outlet 301 is also offset relative to the air inlet 300, and the direction of the offset of the air outlet 301 relative to the air inlet 300 is opposite to the direction of the offset of the central axis of the flow channel 51 relative to the central axis of the exhaust channel 102. Specifically, the central axis of the flow channel 51 is offset towards one side of the housing 1 in the width direction of the housing 1 relative to the central axis of the exhaust channel 102, while the air outlet 301 is offset towards the other side of the housing 1 in the width direction of the housing 1 relative to the air inlet 300. Therefore, in case that the external air flows into the intake channel 31 from the air inlet 300, the external air flows towards the air outlet 301 away from the flow channel 51, that is, the external air enters the atomization chamber 101 from the side away from the flow channel 51, so that the airflow path is extended, thereby prolonging the residence time of the air in the atomization chamber 101, and improving the mixing degree between the air and the aerosol. Therefore, the air flowing in from the lower cover 3 can be mixed more fully with the aerosol in the atomization chamber 101. Then, the mixed gas in the atomization chamber 101 enters the flow channel 51 and then enters the exhaust channel 102, that is, the fully mixed gas can optimize the smoker's inhalation experience.

Furthermore, the housing 1 has a length direction, a width direction, and a thickness direction, and the exhaust channel 102 extends approximately along the length direction. A size of housing 1 in the length direction can be greater than a size in the width direction, and the size in the width direction can be greater than a size in the thickness direction. Under such a situation, the housing 1 can be in a structure of a long bar with a thin thickness, and the electronic cigarette can be an ultra-thin electronic cigarette.

Referring to FIG. 5, in an embodiment, the intake channel 31 includes a first channel 311 and a second channel 312. A first end of the first channel 311 is configured as the air inlet 300, a first end of the second channel 312 is connected to a second end of the first channel 311, and a second end of the second channel 312 is configured as the air outlet 301. In the width direction, a central axis of the second channel 312 is offset towards the side, away from the bracket 5, of the housing 1 relative to a central axis of the first channel 311.

For example, the intake channel 31 extends in an up-down direction, with the first channel 311 located below the second channel 312. A lower end of the first channel 311 is configured as the air inlet 300, and a lower end of the second channel 312 is in directly or indirectly communication with an upper end of the first channel 311. An upper end of the second channel 312 is configured as the air outlet 301. In a left-right direction, an axis of the first channel 311 is offset from an axis of the second channel 312. The cross-section of the first channel 311 perpendicular to the length direction may be partially overlapped with or completely offset the cross-section of the second channel 312 perpendicular to the length direction, both of which are within the scope of protection of this disclosure.

In this embodiment, the central axis of the second channel 312 is arranged further away from the bracket 5, which can facilitate the air outlet 301 is offset towards one side, away from the bracket 5, of the housing 1 relative to the air inlet 300 in the width direction.

Referring to FIG. 5, in an embodiment, the intake channel 31 further includes a third channel 313, the third channel 313 is extended along the width direction. A first end of the third channel 313 in the width direction is connected to the second end of the first channel 311, and a second end of the third channel 313 in the width direction is connected to the first end of the second channel 312.

In this embodiment, the third channel 313 is connected to the first channel 311 and the second channel 312, so that it is beneficial that the direction of the airflow flowing into the intake channel 31 through the air inlet 300 is changed, thereby reducing the difficulty of forming the intake channel 31. Referring to FIG. 5, in an embodiment, at least two distribution holes 41 are formed in the intake distribution plate 4.

In this specific example, multiple distribution holes 41 are formed on the intake distribution plate 4, so that the airflow can be more evenly dispersed and the smoothness of the air intake is improved.

Referring to FIG. 1-FIG. 5, in an embodiment, the intake channel 31 includes an air inlet 300 in communication with the outside and an air outlet 301 in communication with the atomization chamber 101, and at least two of the distribution holes 41 are uniformly distributed within a boundary of the air outlet 301 relative to the air outlet 301.

In this specific example, the distribution holes 41 that are evenly distributed can more effectively buffer the airflow, slow down the flow velocity of the airflow, so that the airflow enter the atomization chamber 101 uniformly. In case that the external air enters an internal structure of the atomization device of the electronic cigarette through the intake channel 31 of the lower cover 3, multiple distribution holes 41 that are evenly distributed can more effectively reduce the collision and vibration of the airflow on the atomization surface, thereby further reducing the noise.

Referring to FIG. 1-FIG. 5, in an embodiment, nine distribution holes 41 are formed in the intake distribution plate 4, and the nine distribution holes 41 are arranged in a three-row and three-column array.

In this specific example, the nine distribution holes 41 are arranged in an array of three rows and three columns, so that the smoothness of the air intake and a more uniform distribution of the airflow can be ensured, which has the effect of making the size and direction of airflow more stable, thereby further ensuring that the noise caused by the airflow during inhalation by the smoker can be reduced.

Referring to FIG. 1-FIG. 5, in an embodiment, an aperture of the distribution holes 41 is in a range of 0.3 mm to 0.8 mm.

In this specific example, the aperture of the distribution holes 41 is set in a range of 0.3 mm˜0.8 mm. This is because a too small aperture of the distribution holes 41 will affect the smoothness of passage of the airflow, while a too large aperture of the distribution holes 41 may cause leakage of the condensate liquid from the distribution holes 41. Therefore, in this embodiment, the aperture of the distribution holes 41 is set in a range of 0.3 mm˜0.8 mm, which can ensure the smoothness of the air intake and avoid leakage of the condensate liquid.

Referring to FIG. 1-FIG. 5, in an embodiment, a sum of areas of at least two of the distribution holes 41 is in a range of 1.2 m²˜1.8 m².

In this specific example, in case that the sum of the areas of the distribution holes 41 is in the range of 1.2 m² to 1.8 m², a good intake buffering effect and leakage prevention effect can be achieved.

Referring to FIG. 1-FIG. 5, in an embodiment, a thickness of the intake distribution plate 4 is in a range of 0.1 mm to 0.3 mm.

In case that the thickness of the intake distribution plate 4 is too thin, the buffering effect of the distribution holes 41 therein on the airflow will be weakened. In case that the thickness of the intake distribution plate 4 is too thick, too much space in the atomization chamber 101 will be occupied. Therefore, in this specific example, the thickness of the intake distribution plate 4 is in the range of 0.1 mm to 0.3 mm.

Referring to FIG. 1-FIG. 5, in an embodiment, the atomization device of the electronic cigarette further includes conductive pins 6. The conductive pins 6 are penetrated through the lower cover 3. Avoidance notches 43 for avoiding the conductive pins 6 are formed in the intake distribution plate 4.

In this specific example, the conductive pins 6 are penetrated through the lower cover 3 and come into contact with the heating element of the atomization core 20 to form an electrical connection. The conductive pins 6 are configured to form an electrical connection between the atomization core assembly 2 and other power supply device. The intake distribution plate 4 is partly penetrated through the conductive pins 6, so that the avoidance notches 43 formed in the intake distribution plate can play a role of avoiding the conductive pins 6, thereby positional interference between the intake distribution plate 4 and the conductive pins 6 are avoided.
