Description

Technical Field

[0001] This application relates to the field of atomization technology, and particularly to an atomization component and an atomization device thereof. Background Art

[0002] An aerosol is a colloidal dispersion system formed by solid or liquid small particles dispersed and suspended in a gas medium. Since aerosols can be absorbed by the human body through the respiratory system, it provides a new alternative absorption method for users. An atomization device refers to a device that forms an aerosol by heating or ultrasonic means on a stored atomizable medium. The atomizable medium includes a liquid, a gel, a paste, or a solid aerosol generation matrix. Atomizing these media can deliver an inhalable aerosol to the user, replacing the conventional product form and absorption method.

[0003] However, with the development of the miniaturization of the atomization device, it is difficult for the atomization medium stored in the atomization device to flow smoothly into the atomization unit for heating and atomization, resulting in a dry burning phenomenon in the atomization unit due to insufficient liquid supply, which in turn affects the quality of the aerosol and the service life of the atomization unit. Summary of the Invention

[0004] Based on this, in view of the problem of poor flow of the atomization medium in the atomization device, it is necessary to provide an atomization component and an atomization device thereof.

[0005] An atomization component includes:

[0006] An atomization tube having a liquid storage cavity and a receiving cavity located on one side of the liquid storage cavity;

[0007] A heating top cover received in the receiving cavity, and an atomization cavity is formed on one side of the heating top cover; and

[0008] A heating element received in the atomization cavity;

[0009] Wherein, a liquid downward channel is formed between the side wall of the heating top cover and the tube wall of the atomization tube, and the liquid downward channel connects the liquid storage cavity and the heating element.

[0010] In one embodiment, the side wall of the heating top cover is recessed inward to form a liquid downward groove, and a liquid downward port connecting the liquid downward groove and the heating element is formed on the groove wall of the liquid downward groove. The liquid downward groove and the tube wall of the atomization tube jointly form the liquid downward channel.

[0011] In one embodiment, the distance between the two ends of the liquid downward channel in the circumferential direction of the atomization tube is greater than or equal to 2.4 mm. In one embodiment, the heating element has a heating surface for heating the atomization medium, and the heating surface is parallel to the radial direction of the atomization tube.

[0012] In one embodiment, the atomization component further includes a top cover seal, which is sleeved outside the heating top cover and surrounds the liquid supply channel. The outer surface of the top cover seal protrudes with a sealing rib, and the sealing rib abuts against the tube wall of the atomization tube. Part of the sealing rib surrounds the liquid supply channel.

[0013] In one embodiment, the heating top cover is provided with a ventilation slot, and the ventilation slot communicates the external atmosphere with the liquid supply channel.

[0014] In one embodiment, the liquid supply channel has a liquid outlet communicating with the heating element, and one end of the ventilation slot extends to the liquid outlet and is connected to the liquid outlet.

[0015] In one embodiment, the heating element has a liquid absorption surface for absorbing the atomization medium, and the distance between the end of the ventilation slot communicating with the liquid supply channel and the liquid absorption surface is 0.

[0016] In one embodiment, the length of the ventilation slot is 6 mm to 16 mm.

[0017] An atomization device includes the above-mentioned atomization component. The atomization device further includes a battery component, and the battery component is connected to one end of the atomization component and is electrically connected to the atomization component.

[0018] For the above-mentioned atomization component, since the liquid supply channel is formed between the side wall of the heating top cover and the tube wall of the atomization tube, while the atomization device is developing towards miniaturization in volume, the liquid supply channel can still have a relatively large cross-sectional area, so as to ensure that the atomization medium in the liquid storage cavity can smoothly flow into the atomization cavity through the liquid supply channel, thereby ensuring sufficient liquid supply to the heating element, effectively preventing the heating element from being damaged due to dry burning, and at the same time avoiding the aerosol generated by the atomization of the atomization medium from generating a burnt smell.

[0033] Refer to Figure 1 , an embodiment of this application provides an atomization device 100 for heating an atomization medium to generate an aerosol for user use. The atomization medium includes, but is not limited to, liquid medicines and oils of materials for medical, health preservation, health, and beauty purposes.

[0034] The electronic atomization device 100 includes an atomization component 20 and a battery component 40. The battery component 40 is mutually mated with the atomization component 20, and the battery component 40 is electrically connected to the atomization component 20 to provide electrical energy for the atomization component 20. The atomization component 20 is used for storing atomization liquid. The atomization component 20 can heat the atomization medium under the action of the electrical energy of the battery component 40 to generate an aerosol for the user to take.

[0035] Please refer to Figure 2 , the atomization component 20 includes an atomization tube 21, an exhaust pipe 23, a mouthpiece 25, and an atomization unit 27 that are mutually mated.

[0036] The atomization tube 21 has an air tube structure with one end open. One end of the atomization tube 21 near the open end forms a receiving cavity communicating with the open end. One end of the exhaust pipe 23 communicates with the receiving cavity, and the other end of the exhaust pipe 23 extends to the closed end of the atomization tube 21. An exhaust passage 23a communicating with the receiving cavity is formed in the exhaust pipe 23. A liquid storage cavity 21a is formed inside the atomization tube 21 at the end far from the open end. The liquid storage cavity 21a surrounds the exhaust pipe 23 in the circumferential direction and is used to store the atomization medium.

[0037] One end of the mouthpiece 25 is inserted into the closed end of the atomization tube 21, and the other end of the mouthpiece protrudes from the atomization tube 21. The mouthpiece 25 forms a suction airway 25a communicating the exhaust passage 23a with the external atmosphere. The atomization unit 27 is housed in the receiving cavity. One end of the exhaust pipe 23 is inserted into the atomization unit 27 so that the exhaust passage 23a communicates with the atomization unit 27. The battery assembly 40 is connected to one end of the atomization assembly 20 provided with the atomization unit 27, and the battery assembly 40 is electrically connected to the atomization unit 27 to supply power to the atomization unit 27.

[0038] Thus, the atomization medium is stored in the liquid storage cavity 21a. The atomization medium stored in the liquid storage cavity 21a can flow into the atomization unit 27 and be heated and atomized by the atomization unit 27. The aerosol generated by atomization can flow out through the exhaust passage 23a and the suction airway 25a in sequence from the atomization cavity 27a for the user to use.

[0039] Please continue to refer to Figure 2 , in some embodiments, the atomization unit 27 includes a heating base 271, a heating top cover 272, a heating element 273, a heating element seal 274, and two electrical connectors 275.

[0040] Both the heating base 271 and the heating top cover 272 have a hollow housing structure. The heating base 271 is connected to the open end of the atomization tube 21, and the heating top cover 272 is connected to one end of the heating base 271 facing the liquid storage cavity 21a. An atomization cavity 27a communicating with the exhaust passage 23a is jointly formed between the heating base 271 and the heating top cover 272.

[0041] The heating element 273 is housed in the atomization cavity 27a, and the heating element seal 274 covers the side of the heating element 273 facing the liquid storage cavity 21a. The electrical connectors 27 are thimble-shaped. Two electrical connectors 27 are provided on the side of the heating element 273 facing away from the liquid storage cavity 21a. The two electrical connectors 27 are arranged at intervals. One end of each electrical connector 275 abuts against the side of the heating element 273 facing away from the liquid storage cavity 21a, and the other end of each electrical connector 275 passes through the heating base 271 and is electrically connected to the battery assembly 40. In some other embodiments, the electrical connectors 27 can also be conductive elements such as wires and electrical patches.

[0042] Further, the heating element 273 has a cubic structure and can be formed of porous materials with high temperature resistance such as porous glass, porous ceramics or honeycomb ceramics. In the following embodiments, the height direction of the heating element 273 is defined as the first direction (i.e., the Z direction in Figure 2 , the length direction of the heating element 273 is defined as the second direction (i.e., the X direction in Figure 2 ), and the width direction of the heating element 273 is defined as the third direction (i.e., the Y direction in Figure 3 ). The first direction, the second direction and the third direction intersect pairwise. As a preferred embodiment, the first direction, the second direction and the third direction are perpendicular to each other pairwise.

[0043] The heating element 273 has a liquid absorption surface for absorbing the atomization medium and a heating surface for heating the atomization medium. In some embodiments, the liquid absorption surface of the heating element 273 is located on the side of the heating element 273 facing the liquid storage cavity 21a and is parallel to the radial direction of the atomization tube 21, and the heating surface of the heating element 273 is located on the side of the heating element 273 facing away from the liquid storage cavity 21a and is parallel to the radial direction of the atomization tube 21.

[0044] Specifically, the surface of the heating element 273 on the side facing away from the liquid storage cavity 21a is covered with a metal material or an alloy material. The alloy material can be selected from ferrochrome alloy, ferrochromaluminum alloy, ferrochromenickel alloy, chromenickel alloy, titanium alloy, stainless steel alloy, etc. The above metal material or alloy material is formed on one side surface of the heating element 273 by processes such as die stamping, casting, mechanical weaving, chemical etching or screen printing. Thus, the atomization assembly 20 of the present application forms a downward atomization structure, and the aerosol is formed from the heating surface of the heating element 273 facing away from the liquid storage cavity 21a.

[0045] It can be understood that in some other embodiments, the heating surface of the heating element 273 can also be formed on the side surface of the heating element 273 facing the liquid storage cavity 21a or on the side wall parallel to the first direction, so as to form an upward atomization or lateral atomization structure to meet different atomization requirements.

[0046] As described in the background art, in order to allow the atomization medium in the liquid storage cavity 21a to flow into the atomization cavity 27a, a liquid discharge hole communicating with the atomization cavity 27a is usually opened at the top of the end of the heating top cover 272 facing the liquid storage cavity 21a in the prior art. However, the cross-sectional area of the liquid discharge hole is proportional to the volume of the atomization device 100. As the volume of the atomization device 100 develops towards miniaturization, the cross-sectional area of the liquid discharge hole decreases. Therefore, it is easy to form bubbles on the surface of the heating top cover 272, making it difficult for the atomization medium to flow, and further causing the atomization unit 27 to produce a burnt smell due to insufficient liquid supply, and at the same time causing the atomization unit 27 to be damaged due to dry burning.

[0047] Based on the above problems, a liquid-down channel 20a is formed between the side wall of the heating top cover 272 and the tube wall of the atomizing tube 21 in this application. The liquid-down channel 20a connects the liquid storage cavity 21a and the atomizing cavity 27a, and the atomizing medium in the liquid storage cavity 21a can flow into the heating element 273 through the liquid-down channel 20a.

[0048] Since the liquid-down channel 20a is formed between the side wall of the heating top cover 272 and the tube wall of the atomizing tube 21, while the volume of the atomizing device 100 is miniaturized, the liquid-down channel 20a can still have a relatively large cross-sectional area, so as to ensure that the atomizing medium in the liquid storage cavity 21a can smoothly flow into the atomizing cavity 27a through the liquid-down channel 20a, thereby ensuring sufficient liquid supply to the heating element 273, effectively preventing the heating element 273 from being damaged due to dry burning, and at the same time avoiding the generation of burnt smell from the aerosol generated by atomizing the atomizing medium.

[0049] Please refer to Figure 2 、 Figure 3 and Figure 4 As shown, one end side wall of the heating top cover 272 facing the liquid storage cavity 21a is recessed inward to form a liquid-down groove 272a. A liquid-down port 2723a connecting the liquid-down groove 272a and the atomizing cavity 27a is formed on the groove wall of the liquid-down groove 272a. The liquid-down groove 272a and the tube wall of the atomizing tube 21 jointly form the liquid-down channel 20a.

[0050] As a preferred embodiment, two liquid-down grooves 272a are formed on the heating top cover 272. The two liquid-down grooves 272a are located on opposite sides of the heating top cover 272 in the second direction, thus forming two liquid-down channels 20a. It can be understood that the number of the liquid-down channels 20a is not limited to this, and can be set according to needs to meet different liquid-down requirements.

[0051] Specifically, in an embodiment, the liquid-down groove 272a has a groove bottom wall 2721, a first groove side wall 2723 and two second groove side walls 2725. The groove bottom wall 2721 is located at one end of the liquid-down groove 272a far from the liquid storage cavity 21a, and the groove bottom wall 2721 is a plane perpendicular to the first direction. The first groove side wall 2723 is located on one side of the groove bottom wall 2721 close to the central axis of the liquid storage cavity 21a in the second direction, and the first groove side wall 2723 is a plane perpendicular to the second direction. The two second groove side walls 2725 are spaced on opposite sides of the groove bottom wall 2721 in the third direction, and the first groove side wall 2723 is connected between the two second groove side walls 2725.

[0052] Thus, the bottom wall 2721 of the groove, the first side wall 2723 of the groove, the second side wall 2725 of the groove, and the tube wall of the atomization tube 21 together form a liquid-down channel 20a. A liquid-down port 2723a is opened on the side of the first side wall 2723 of the groove close to the bottom wall 2721 and extends to the bottom wall 2721. As a preferred embodiment, the distance between the two second side walls 2725 of the groove (i.e., the distance between the two ends of the liquid-down channel 20a in the circumferential direction of the atomization tube 21) is greater than or equal to 2.4 mm, so that the atomization medium can flow smoothly in the liquid-down channel 20a. It can be understood that the size of the liquid-down channel 20a is not limited to this and can be set as needed to enable the atomization medium to flow smoothly.

[0053] In some embodiments, the atomization assembly 20 further includes a top cover seal 276. The top cover seal 276 has a cylindrical structure with one end open. The top cover seal 276 is sleeved outside the heating top cover 272. A communication port 276a communicating with the liquid-down channel 20a is opened on the side wall of the top cover seal 276. The top cover seal 276 is used to seal the gap between the atomization tube 21 and the heating top cover 272 to prevent the atomization medium in the liquid-down channel 20a from leaking along the gap between the atomization tube 21 and the heating top cover 272. Specifically, in one embodiment, corresponding to the two liquid-down channels 20a, two communication ports 276a are opened on the side wall of the top cover seal 276. The two communication ports 276a are spaced apart in the second direction, and each communication port 276a communicates with one liquid-down channel 20a.

[0054] Furthermore, a sealing rib 2762 is convexly provided on the outer surface of the top cover seal 276. The sealing rib 2762 abuts against the tube wall of the atomization tube 21, and a part of the sealing rib 2762 surrounds the liquid-down channel 20a, so as to play a good sealing role to prevent the atomization medium from leaking.

[0055] Specifically, two sealing ribs 2762 are convexly provided on the top cover seal 276. The two sealing ribs 2762 are respectively located at the opposite ends of the top cover seal 276 in the first direction. One of the sealing ribs 2762 circumferentially surrounds one end edge of the top cover seal 276. Since the communication port 276a is opened on the top cover seal 276, a part of the other sealing rib 2762 surrounds one end edge of the top cover seal 276 and partly winds around the communication port 276a.

[0056] In some embodiments, in order to balance the air pressure inside and outside the liquid storage cavity 21a, the heating top cover 272 is provided with a ventilation groove 272b. The ventilation groove 272b communicates the external atmosphere with the liquid-down channel 20a. Thus, when the atomization medium in the liquid storage cavity 21a flows into the atomization cavity 27a through the liquid-down channel 20a, external air can enter the liquid-down channel 20a through the ventilation groove 272b to ensure the smooth flow of the atomization medium.

[0057] Specifically, one end of the air exchange groove 272b penetrates through the side wall of the top cover seal 276 away from the liquid storage cavity 21a, and the other end of the air exchange groove 272b bends and extends until it communicates with the liquid downward channel 20a. The top cover seal 276 covers the part of the air exchange groove 272b on the side wall of the top cover seal 276.

[0058] Specifically in one embodiment, one end of the air exchange groove 272b extends to the side edge of the liquid downward groove 272a away from the liquid storage cavity 21a to communicate with the liquid downward channel 20a. More specifically, one end of the air exchange groove 272b extends to any position of the bottom wall 2721 of the liquid downward groove 272a. Preferably, one end of the air exchange groove 272b extends to the side edge of the bottom wall 2721 away from the first groove side wall 2723. In some other embodiments, the air exchange groove 272b may also extend to any position of the first groove side wall 2723 or the second groove side wall 2725 of the liquid downward groove 272a.

[0059] As Figure 5 And Figure 6 As shown, specifically in another embodiment, one end of the air exchange groove 272b extends to the liquid downward port 2723a opened on the groove side wall of the liquid downward groove 272a and communicates with the liquid downward port 2723a. As a preferred embodiment, the end of the air exchange groove 272b communicating with the liquid downward port 2723a is close to the heating element 273, and the end of the air exchange groove 272b communicating with the liquid downward port 2723a is as close as possible to the heating element 273. Preferably, the distance between the end of the air exchange groove 272b communicating with the liquid downward port 2723a and the liquid absorption surface of the heating element 273 is 0, so as to guide the air flow to the liquid absorption surface of the heating element 273. In other embodiments, the end of the air exchange groove 272b communicating with the liquid downward channel 20a is close to the heating element 273, and the end of the air exchange groove 272b communicating with the liquid downward channel 20a is as close as possible to the heating element 273. Preferably, the distance between the end of the air exchange groove 272b communicating with the liquid downward channel 20a and the liquid absorption surface of the heating element 273 is 0. Specifically in one embodiment, the length of the air exchange groove 272b is 6 mm - 16 mm. It can be understood that the specific length and shape of the air exchange groove 272b can be set according to needs to meet different air exchange requirements.

[0060] For the above atomization assembly 20 and atomization device 100, the liquid downward channel 20a connecting the liquid storage cavity 21a and the atomization cavity 27a is formed between the tube walls of the heating top cover 272 and the atomization tube 21. Compared with the liquid downward channel 20a only opened on the heating top cover 272, when the atomization device 100 has the same size, the liquid downward channel 20a of the present application has a larger cross-sectional area, so as to ensure the smooth flow of the atomization medium while meeting the miniaturization of the atomization device 100, effectively prevent the heating element 273 from being damaged due to insufficient liquid supply and dry burning, and at the same time effectively prevent the aerosol from generating a burnt smell, improving the user experience.

[0061] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification.

[0062] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
