The atomizer 100 according to the embodiment includes a bottom cover 10, an elastic support 20, an atomization core 30, a housing 40 and electrodes 50. The housing 40 internally defines a liquid storage cavity 28 for storing a liquid matrix. Specifically, the housing 40 accommodates the elastic support 20, the atomization core 30 and the bottom cover 10. The elastic support 20 matches an inner wall of the housing 40 to form the liquid storage cavity 28. The bottom cover 10 covers an open end of the housing 40, and the elastic support 20 is connected to the bottom cover 10. The atomization core 30 is arranged inside the elastic support 20. The electrodes 50 are arranged on the bottom cover 10 and are electrically connected to the atomization core 30. The liquid storage cavity 28 is used for storing the liquid matrix and supplying a liquid to the atomization core 30, and the atomization core 30 is used for atomizing the liquid matrix and generating an aerosol. The elastic support 20 is at least partially used for sealing the liquid storage cavity 28 while the elastic support 20 matches the housing 40 to form the liquid storage cavity 28.
In the embodiment, the elastic support 20 is a structure formed integrally. The elastic support 20 is made of an elastic material, for example, silica gel or elastic rubber. Further, the atomization core 30 is arranged on the elastic support 20 such that a sealing member between the atomization core 30 and the elastic support 20 can be relatively eliminated. That is, the atomization core 30 can be in sealing fit with the elastic support 20 through a characteristic of the elastic support 20 when the atomization core 30 is arranged on the elastic support 20. Moreover, the elastic support 20 can be further in sealing fit with the bottom cover 10 and the housing 40. Thus, the number of components of the atomizer 100 is reduced, and material cost and assembly cost of the atomizer can be greatly reduced.
As shown in FIG. 4 and FIG. 5, the elastic support 20 includes a top wall 22 and a ring wall 23 connected to each other, two liquid discharge grooves 24 are provided on the outer surface of the elastic support 20, the liquid discharge grooves 24 extend from the top wall 22 to the ring wall 23, the portions of the two liquid discharge grooves 24 located on the top wall 22 are independent of each other, and the liquid discharge grooves 24 are in fluid communication with part of a surface of the atomization core 30. The elastic support 20 matches the housing 40 to form the liquid storage cavity 28, portions of the liquid discharge grooves 24 located on the top wall 22 are in communication with the liquid storage cavity 28, and a liquid matrix in the liquid storage cavity 28 flows to the atomization core 30 through the liquid discharge grooves 24. By designing a structure of the liquid discharge grooves 24 on the elastic support 20 as above, a traditional let-right side liquid inlet manner is changed into a side liquid inlet manner, thereby improving uniformity of liquid supply of the atomization core 30.
In the embodiment, as shown in FIG. 3 and FIG. 4, the elastic support 20 is connected to the bottom cover 10 and matches the bottom cover 10 to define an atomization cavity 21, the top wall 22 of the elastic support 20 is provided with an air outlet 25, and the air outlet 25 is in communication with the atomization cavity 21. The atomization core 30 is arranged on the elastic support 20, the atomization core 30 is arranged side by side with the atomization cavity 21 in a perpendicular direction Y of an air outlet direction X of the air outlet 25, an atomization surface 31 of the atomization core 30 is substantially parallel to the air outlet direction X, and the atomization core 30 generates an aerosol in the atomization cavity 21. The aerosol is guided into an oral cavity of a user through the air outlet 25. That is, in the embodiment, an atomization mode is side atomization. It should be noted that a structure of the atomizer 100 according to the embodiment of the present application is also applicable to an upper atomization mode (the atomization surface 31 faces the air outlet 25) or a lower atomization mode (the atomization surface 31 faces away from the air outlet 25), as long as an orientation of the atomization surface 31 of the atomization core 30 and a position of the atomization core 30 on the elastic support 20 are adaptively changed. The structure of the atomizer 100 will be described below in detail by using side atomization as an embodiment.
A gas channel 41 is further formed on the housing 40, and the air outlet 25 is in communication with the gas channel 41, so as to guide the aerosol generated in the atomization cavity 21 into the oral cavity of the user. An air intake vent 11 is provided on the bottom cover 10, the air intake vent 11 is in communication with the atomization cavity 21, and the atomization cavity 21 is in communication with external air through the air intake vent 11, so as to supply air to the atomization cavity 21. The external air enters the atomization cavity 21 through the air intake vent 11, and carries the aerosol in the atomization cavity 21 to flow to the gas channel 41 through the air outlet. A user inhales the aerosol through a port of the gas channel 41.
The air intake vent 11, the atomization cavity 21 and the air outlet 25 are sequentially provided in the air outlet direction X of the air outlet 25, the atomization core 30 is arranged side by side with the atomization cavity 21 in the perpendicular direction Y of the air outlet direction X of the air outlet 25, and the atomization surface 31 of the atomization core 30 faces the atomization cavity 21 and is substantially parallel to the air outlet direction X of the air outlet 25. Thus, an air flow channel from the air intake vent 11 to the air outlet 25 is a straight channel and passes through the atomization cavity 21, so as to avoid the situation that air flow entering through the air intake vent 11 is blocked by the atomization core 30, and reduce a dead corner area of the air flow, and a turning structure in an air passage is eliminated. Moreover, the air flow can cross the atomization core 30 more smoothly in the air outlet direction X to more fully and efficiently carry away the aerosol generated by the atomization core 30, a paste core can be effectively reduced, and a distance from the aerosol to the oral cavity of the user is effectively shortened. Further, the aerosol can enter the oral cavity of the user at a higher temperature, thereby improving taste of the aerosol.
The air intake vent 11 and the air outlet 25 are coaxially provided. Projections of the atomization core 30 and the air intake vent 11 in a plane perpendicular to the air outlet direction X do not overlap each other, such that the air flow channel from the air intake vent 11 to the air outlet 25 is the straight channel, the situation that the air flow entering through the air intake vent 11 is blocked by the atomization core 30 can be avoided, and the dead corner area of the air flow is reduced. The air flow completely covers the atomization surface 31 of the atomization core 30, thereby reducing the paste core, and improving taste.
Continuously, with reference to FIG. 3, an inner wall of the elastic support 20 is provided with a mounting groove 27, the atomization core 30 is mounted in the mounting groove 27, the atomization core 30 includes a circumferential side surface connected to the atomization surface 31, and the mounting groove 27 is in sealing engagement with the circumferential side surface. Optionally, the atomization core 30 is in interference fit with the mounting groove 27, so as to achieve sealing fit with each other. Optionally, a positioning hole (not shown in the figure) is provided on the elastic support 20, and a positioning column (not shown in the figure) is arranged on the atomization core 30. The positioning column is in positioning fit with the positioning hole, and the elastic support 20 is in sealing fit with the atomization core 30 through a pressing force of the bottom cover 10 to the atomization core 30.
Portions of the liquid discharge grooves 24 located in the ring wall 23 extend in the air outlet direction X parallel to the air outlet 25. It may alternatively be considered that the liquid discharge grooves 24 extend from the top wall 22 along the ring wall 23 towards a bottom end surface of the elastic support 20. It may alternatively be considered that a length direction of portions of the liquid discharge grooves 24 located on the ring wall 23 is parallel to the air outlet direction X. The atomization core 30 is mounted in the mounting groove 27, such that the liquid discharge grooves 24 may be isolated from the atomization cavity 21. The liquid discharge grooves 24 are provided with nicks 231 (as shown in FIG. 6) on a peripheral surface of the ring wall 23. The nicks 231 are covered with an inner wall surface of the housing 40. The nicks 231 of portions of the liquid discharge grooves 24 located on the ring wall 23 face the liquid storage cavity 28, such that the liquid discharge grooves 24 are in communication with the liquid storage cavity 28. Further, a liquid matrix in the liquid storage cavity 28 may supply a liquid to the atomization core 30 arranged in the mounting groove 27 through the liquid discharge grooves 24.
By providing the liquid discharge grooves 24 on the ring wall 23 to reduce a size requirement of the liquid discharge grooves 24 on the elastic support 20, the ring wall 23 of the elastic support 20 can be thin in a width direction of the ring wall, thereby advantageously miniaturizing the atomizer 100 and reducing weight of the atomizer.
In an implementation, portions of two liquid discharge grooves 24 located on a ring wall 23 are independent of each other, and the portions of the two liquid discharge grooves 24 located on the ring wall 23 are each in fluid communication with an atomization core 30.
In an implementation, as shown in FIG. 5, portions of two liquid discharge grooves 24 located on a ring wall 23 are in communication with each other. Optionally, the portions of the liquid discharge grooves 24 located on the ring wall 23 each include a first groove section 241 and a second groove section 242 in communication with each other. The first groove sections 241 are located on one sides of the second groove sections 242 closer to the top wall 22. The two first groove sections 241 are independent of each other, and the two second groove sections 242 are in communication with each other. Widths and/or depths of the first groove sections 241 are substantially consistent in the air outlet direction X parallel to the air outlet 25, thereby advantageously guiding air bubbles generated by exchange between the atomization core 30 and external air into the liquid storage cavity 28, and reducing a probability that flow of a liquid is prevented since a large number of air bubbles are accumulated in the first groove sections 241.
In an implementation, bottom walls of portions of liquid discharge grooves 24 located at a joint between a top wall 22 and a ring wall 23 are cambered surfaces, thereby improving smoothness of flow of a liquid matrix in the liquid discharge grooves 24. Optionally, the cambered surfaces are bulged towards the liquid discharge grooves 24 to avoid dead corner areas of the liquid matrix at the portions of the liquid discharge grooves 24 located at the joint between the top wall 22 and the ring wall 23.
With reference to FIG. 5 and FIG. 6, an outer surface ring of the elastic support 20 is provided with a sealing rib 26, part of the sealing rib 26 extends along an outer contour shape of portions of the two liquid discharge grooves 24 located on the ring wall 23, and the sealing rib 26 elastically presses against an inner wall surface of the housing 40 of the atomizer 100. The sealing rib 26 can prevent a liquid aerosol generating matrix from seeping from the liquid discharge grooves 24 while achieving sealing fit between the elastic support 20 and the housing 40.
The elastic support 20 further includes a spacing portion 2401 located between the two liquid discharge grooves 24. The spacing portion 2401 elastically abuts against the inner wall surface of the housing 40. Thus, on one hand, the liquid storage cavity is partially sealed, and on the other hand, lateral elastic support is provided for the atomization core 30 mounted inside the elastic support 20, such that the atomization core 30 makes excellent contact with the electrodes 50 located on one side of the atomization core 30.
With reference to FIG. 7 and FIG. 8, one side of the elastic support 20 facing away from the top wall 22 is provided with an annular insertion groove 29. The bottom cover 10 is provided with an insertion portion 12. The insertion portion 12 is inserted into the insertion groove 29 to connect the elastic support 20 to the bottom cover 10. The ring wall 23 of the elastic support 20 is arranged on at least part of the bottom cover 10 to seal the elastic support 20 and the bottom cover 10, and provides an elastic force in the perpendicular direction Y of the air outlet direction X of the air outlet 25, thereby causing the atomization core 30 to elastically press against the bottom cover 10, so as to further stabilize the atomization core 30.
A connection manner between the elastic support 20 and the bottom cover 10 is simple, and assembly cost is low. Moreover, the atomization core 30 can be further fixed through matching between the elastic support and the bottom cover 10, thereby advantageously improving structural stability of the atomizer 100, and further reducing a shifting risk of the atomization core 30 in the atomizer 100.
Continuously, with reference to FIG. 5 to FIG. 7, the atomizer 100 further includes electrodes 50. The electrodes 50 are arranged on the bottom cover 10. Two electrode mounting holes 13 are provided on a bottom wall of the bottom cover 10, and are used for mounting the electrodes 50. The air intake vent 11 is provided on the bottom wall of the bottom cover 10, and the air intake vent 11 is provided between the two electrode mounting holes 13. The elastic support 20 causes the atomization core 30 to elastically press against the electrodes 50 in the perpendicular direction Y of the air outlet direction X of the air outlet 25, such that the electrodes 50 are electrically connected to the atomization core 30. That is, the atomization core 30 may make contact with the electrodes 50 through a rebound force of the elastic support 20, so as to achieve electrical connection. The electrodes 50 are connected to the bottom cover 10 in the air outlet direction X of the air outlet 25.
The electrodes 50 are connected to the bottom cover 10 in the air outlet direction X of the air outlet 25.
