Referring to FIG. 1 to FIG. 7, in the embodiment of the invention, the atomizer 100 is detachably mounted on a power supply base 200, the power supply base 200 is provided with a receiving chamber 210, wherein the atomizer 100 comprises a main body 10, an atomizing component 30 and a flexible protective sleeve 50, the main body 10 is provided with an air inlet 126, an oil storage chamber 13, a suction part 11 provided with an air outlet 111, and an inserting part 12 for being inserted into the receiving chamber 210, the main body 10 forms an airflow passage between the air inlet 126 and the air outlet 111, the atomizing component 30 is provided in the airflow passage and is communicated with the oil storage chamber 13, and the protective sleeve 50 is sleeved on the outer surface of the suction part 11 and is provided with a suction opening 51 communicated with the air outlet 111.

According to the atomizer 100 of the technical solution of the invention, the suction part 11 is provided with a flexible protective sleeve 50 which is made of non-toxic silicone material, and the flexible protective sleeve 50 is provided with a suction opening 51 communicated with the air outlet 111 for the user to smoke. When the user smokes, the protective sleeve 50 of the flexible material is in direct contact with the oral cavity of the user, effectively preventing the phenomenon that the suction part 11 having a higher temperature is in direct contact with the oral cavity to get mouth scalded; at the same time, compared with the conventional hard suction part 11, the flexible protective sleeve 50 has a certain deformation performance, preventing the uncomfortable feeling resulted from the irregular side structure. At the same time, the protective sleeve 50 made of non-toxic silicone material can be bitten by the user with the taste of biting nipples, effectively improving the taste that the user bites hard material and enhancing the interest.

Specifically, as shown in FIG. 4, in the embodiment of the invention, one of an inner wall of the protective cover 50 and an outer surface of the suction part 11 is provided with at least one first connecting part 112, and the other thereof is provided with at least one second connecting part 52, and one of the first connecting parts 112 and one of the second connecting parts 52 are cooperatively connected to mount the protective cover 50 in the suction part 11. Here, in the present embodiment, the inner circumference of the end of the protective sleeve 50 is convexly provided with a limiting flange to form the second connecting part 52. Further, the outer circumference of the suction part 11 is correspondingly provided with an annular groove to form the first connecting part 112. When the protective sleeve 50 is sleeved on the suction part 11, the limiting flange is buckled in the annular groove, and the protective sleeve 50 is fixed to the suction part 11, effectively preventing the phenomenon that the protective sleeve 50 falls off.

It is to be understood that, in practical applications, the first connecting part 112 and the second connecting part 52 are not limited to the manner in which the limiting flange and the annular groove are used in the above embodiment. For example, in another embodiment of the invention, the manner in which the protective sleeve 50 and the suction part 11 may be fixed by means of a buckle, a snap fastener or a glue, etc., falls within the scope of protection of the invention. Similarly, the number and position of the first connecting part 112 and the second connecting part 52 are not limited to being provided at the end of the protective sleeve 50 in the above embodiment. For example, a plurality of first connecting parts 112 and second connecting parts 52 may be appropriately provided depending on the size of the product, and may be provided at intervals between the protective sleeve 50 and the suction part 11.

Further, as shown in FIG. 1 to FIG. 3, in the embodiment of the invention, the surface of the outer circumference of the protective cover 50 is further provided with a gripping part 53. Here, in the present embodiment, the gripping part 53 is formed by providing inclined grooves on the opposite surfaces of the outer circumference of the protective sleeve 50, effectively facilitating the user to grip the atomizer 100 to be pulled out from the receiving chamber 210 provided by the power supply base 200.

Further, as shown in FIG. 1 to FIG. 4 and FIG. 6, in the embodiment of the invention, one of the surface of the outer circumference of the inserting part 12 and the cavity wall of the inner circumference of the receiving chamber 210 is provided with at least one positioning protrusion 2101, and the other thereof is provided with at least one positioning groove 121 in an obround hole shape, and when the atomizer 100 is inserted into the receiving chamber 210, one of the positioning protrusions 2101 is clamped in the positioning groove 121, so that the atomizer 100 is fixed to the power supply base 200. Here, in the present embodiment, the internal cavity wall of the receiving chamber 210 is convexly provided with two positioning protrusions 2101. The two positioning protrusions 2101 are convexly provided in the two opposite internal cavity walls of the receiving chamber 210. The outer peripheral edge of the main body 10 is correspondingly provided with two positioning grooves 121 in an obround hole shape. Two side groove walls in the width direction of the positioning groove 121 in an obround hole shape abuts against the side structure of the positioning protrusion 2101, and the length extends in the circumferential direction of the receiving chamber 210. When the main body 10 of the atomizer 100 is inserted into the receiving chamber 210, the two positioning protrusions 2101 are clamped in the positioning groove 121, so that the main body 10 of the atomizer 100 is fixed to the power supply base 200, effectively preventing the phenomenon that a circular positioning groove 121 is provided conventionally, and when the mounting accuracy is poor, the positioning protrusion 2101 cannot be smoothly clamped in the positioning groove 121 so as to result in unstable mounting.

It is to be understood that, in practical applications, the shape of the positioning groove 121 is only limited to the manner of using an obround hole as described above. For example, in another embodiment of the invention, the manner in which the positioning groove 121 may also extend in a long distance in the length direction to form a through groove falls within the scope of protection of the invention.

Further, as shown in FIG. 1 to FIG. 3, in the embodiment of the invention, one of the surface of the outer circumference of the inserting part 12 and the cavity wall of the inner circumference of the receiving chamber 210 is further convexly provided with a plurality of limiting protrusions 122, and when the atomizer 100 is inserted into the receiving chamber 210, each of the limiting protrusions 122 abuts against the internal cavity wall of the receiving chamber 210 or the surface of the outer circumference of the inserting part 12, so that the atomizer 100 is limited to the power supply base 200. Here, for example, the surface of the outer circumference of the inserting part 12 is provided with a plurality of limiting protrusions 122. When the atomizer 100 is inserted into the receiving chamber 210, the protrusions 122 which are convexly provided abut against the internal cavity wall of the receiving chamber 210 so as to be closely fit, effectively preventing the phenomenon that the atomizer 100 shakes when the atomizer 100 is mounted in the receiving chamber 210. At the same time, there is still a gap between the outer wall of the inserting part 12 where the limiting protrusion 122 is not provided and the receiving chamber 210 through which the airflow passes, without affecting the working air intake of the main body 10 when the user smokes.

Further, as shown in FIG. 1 to FIG. 3, in the embodiment of the invention, one of the surface of the outer circumference of the inserting part 12 and the cavity wall of the inner circumference of the receiving chamber 210 is provided with a plurality of supporting ribs 123, and when the atomizer 100 is inserted into the receiving chamber 210, each of the supporting ribs 123 abuts against the internal cavity wall of the receiving chamber 210 or the surface of the outer circumference of the inserting part 12, so that there is a gap between the surface of the outer circumference of the inserting part 12 and the internal cavity wall of the receiving chamber 210 through which the airflow passes. Here, in the embodiment, the outer peripheral edge of the inserting part 12 is provided with four supporting ribs 123 extending in the axial direction of the receiving chamber 210. Every two supporting ribs 123 are provided at the outer wall of one side of the inserting part 12 at intervals. When the inserting part 12 is inserted into the receiving chamber 210, the supporting rib 123 abuts against the internal cavity wall of the receiving chamber 210, further effectively preventing the phenomenon that the atomizer 100 shakes when being mounted in the receiving chamber 210. At the same time, a supporting space is formed between the two supporting ribs 123, through which the airflow passes, effectively ensuring the working air intake of the atomizer 100 when the user smokes, and preventing the phenomenon that the occurrence of labored breathing results in dry burning of the atomizer 100 due to the fact that the gap between the surface of the outer circumference of the inserting part 12 and the internal cavity wall of the receiving chamber 210 is too small.

Specifically, as shown in FIG. 3 or FIG. 7, in the embodiment of the invention, the inserting part 12 is of light-transmitting material, and the power supply base 200 is provided with at least one oil observing groove 222 exposing the inserting part 12. Here, in the present embodiment, the two opposite side walls of the power supply base 200 are both provided with a through groove exposing the inserting part 12 to form the oil observing groove 222, which facilitates the user to observe the residual amount of tobacco liquid in the oil storage chamber 13. Further, the inserting part 12 is correspondingly provided with a bump inserted into the oil observing groove 222, preventing the phenomenon that external dust enters the receiving chamber 210 from the oil observing groove 222.

It is to be understood that, in practical applications, it is not limited to the manner in which the power supply base 200 is provided with a through groove to form the oil observing groove 222 in the above embodiment. For example, the manner in which the power supply base 200 is partially made of light-transmitting material so as to expose the internal receiving chamber 210 falls within the scope of protection of the invention.

Further, as shown in FIG. 7, in the embodiment of the invention, one of the inserting part 12 and the power supply base 200 is further provided with a notch groove 211, and the other thereof is convexly provided with a positioning pin 124, the inserting part 12 is inserted into the receiving chamber 210 in the direction at which the positioning pin 124 is inserted into the notch groove 211, and the atomizer 100 is positioned at the power supply base 200. Here, in the embodiment, the positioning pin 124 and the notch groove 211 are provided to realize guiding orientation, effectively preventing the phenomenon that when the user inserts the receiving chamber 210 from another angle, the receiving chamber 210 cannot be inserted due to the abutment, or the phenomenon of an electrode reverse connection or a short circuit

It is to be understood that, in practical applications, the manner in which an oil observing groove 222 is provided on one surface of the power supply base 200 so as to distinguish the inserting direction as described above and perform guiding orientation also falls within the scope of protection of the invention.

Further, as shown in FIG. 1 or FIG. 4, in the embodiment of the invention, the inserting part 12 is further provided with at least one oil filling hole 125 communicated with the oil storage chamber 13 and at least one oil sealing plug 20, and one end of the oil sealing plug 20 is pluggably mounted in the oil filling hole 125 for blocking or opening the oil filling hole 125. Here, in the embodiment, the inserting part 12 is provided with an oil filling hole 125, and then is provided with an oil sealing plug 20 made of an elastic silicone material, so that the user may supplement the oil in the oil storage chamber 13, preventing the phenomenon that direct replacement of the atomizer 100 leads to higher use cost; at the same time, when the inserting part 12 is inserted into the receiving chamber 210, the oil filling hole 125 is covered, effectively preventing the phenomenon that the oil sealing plug 20 is accidentally opened so as to result in oil leakage.

Specifically, as shown in FIG. 1, in the embodiment of the invention, the main body 10 comprises a base 34 provided with an air inlet 126 and a housing covering the base 34 and provided with an air outlet 111. An oil storage chamber 13 is encircled between the housing and the base 34. The atomizing component 30 comprises an atomizing shell 31 and a heat generating core 32. The atomizing shell 31 covers the base 34 and encircles an atomizing chamber 312 together with the base 34. The atomizing shell 31 is further provided with an oil guiding hole 311 and an air guiding tube 322. The oil guiding hole 311 is communicated with the oil storage chamber 13 and the atomizing chamber 312. The air guiding tube 322 is communicated with the atomizing chamber 312 and the air outlet 111. The atomizing chamber 312 is communicated with the air inlet 126 and the air outlet 111. The heat generating core 32 is received in the atomizing chamber 312 and is partially exposed from the base 34. Here, in the present embodiment, when the housing is inserted into the receiving chamber 210, an airflow passage is formed between the outer peripheral edge of the housing and the internal cavity wall of the receiving chamber 210. The air inlet 126 is provided at the base 34. The limiting protrusion 122, the positioning protrusion 2101 and the supporting rib are provided on each surface of the inserting part 12, effectively preventing the housing from shaking, and at the same time, ensuring that the external airflow can enter the atomizing chamber 312 through the air inlet 126 after flowing into the airflow passage when the user smokes. The atomizing shell 31 covers the base 34, and encircles an atomizing chamber 312 communicated with the oil storage chamber 13 together with the base 34. The heat generating core 32 is received in the atomizing chamber 312 and is partially exposed from the base 34 to form a contact electrode. When the main body 10 of the atomizer 100 is inserted into the receiving chamber 210, the main body 10 abuts against the output electrode of the power supply base 200 and forms an electrical circuit. When the user smokes, the power supply base 200 drives the heat generating core 32 to heat the tobacco liquid adsorbed by the heat generating core 32 from the oil storage chamber 13 to atomize the tobacco liquid into smoke. At the same time, the external airflow flows into the atomizing chamber 312 through the air inlet 126, and the atomized smoke is mixed and discharged from the air outlet 111 for the user to smoke.

Further, as shown in FIG. 1 or FIG. 4, in the embodiment of the invention, the main body 10 further comprises a sealing member 33. One end of the sealing member 33 is fixedly mounted on the base 34, and the other end thereof is received in the oil storage chamber 13 and is closely fitted with the inner peripheral edge of the housing. Here, in the embodiment, the base 34 is provided with two inserting grooves, and the sealing member 33 is provided with two inserting posts and an avoiding vacancy into which the sleeve is inserted.
