Description

[Technical Field]

[0001] This application relates to the field of atomization technology, and more particularly to an electronic atomization device. [Background Technology]

[0002] Traditional tobacco products (e.g., cigarettes, cigars, etc.) produce tobacco smoke through combustion during use. Existing technologies offer alternatives to these traditional tobacco products by releasing compounds through heating without combustion. Examples of such products are electronic atomizing devices, which typically comprise an atomizable liquid matrix and an atomizing element for atomizing the liquid matrix to produce inhalable vapor or aerosol. The liquid matrix may contain nicotine and / or flavorings and / or aerosol-generating substances (e.g., glycerin).

[0003] Existing electronic atomizing devices also include a filter device containing a filter liquid (such as water) for filtering aerosols. Filtering aerosols can reduce their temperature, dissolve and precipitate some harmful substances, and remove some irritating components, making the vapor smoother and more pleasant to inhale.

[0004] These types of electronic atomizing devices typically include an atomizing unit and a filter unit that work together. The atomizing unit generates an aerosol, which is then guided through an air tube to the filter unit for filtration. The filtered aerosol is then delivered to the inhalation port for the user to inhale. Because the filter unit contains a filtering liquid, it is usually large and heavy, making these electronic atomizing devices with filtering functions inconvenient to carry. [Utility Model Content]

[0024] A first receiving cavity for removably receiving at least a portion of an external filter, the first receiving cavity having a first opening for the external filter to enter;

[0039] One embodiment of this application provides an electronic atomizing device 100, such as... Figure 1 , Figure 2 and Figure 3 As shown, the electronic atomizing device 100 includes an atomizer 10 and a receiver 20. The receiver 20 is provided with a second receiving cavity 21. The second receiving cavity 21 has a second opening 211, which is used to provide an entrance for the atomizer 10 to enter the second receiving cavity 21. After the second receiving cavity 21 receives the atomizer 10, the atomizer 10 will be kept in the second receiving cavity 21 to prevent the atomizer 10 from shaking or shifting in the second receiving cavity 21.

[0040] The atomizer 10 is provided with a liquid storage chamber (not shown) for storing a liquid matrix, and an atomizing component (not shown) for atomizing the liquid matrix to generate an aerosol. The atomizer 10 also includes a first air outlet 11 for the aerosol generated after atomization to escape from the atomizer 10.

[0041] In some embodiments, the atomizing assembly includes a liquid guide (not shown) and a heating element (not shown) attached to the liquid guide. The liquid guide is in communication with a liquid storage chamber, so that the liquid matrix in the liquid storage chamber can flow to the liquid guide and be absorbed by the liquid guide. The liquid guide further transfers the absorbed liquid matrix to the heating element for heating and atomization.

[0042] In some embodiments, the atomizing component may further include an atomizing plate, and a liquid guide is provided between the atomizing plate and the liquid storage chamber. The liquid guide can conduct the liquid matrix in the liquid storage chamber to the atomizing plate. The controller of the atomizer 10 controls the atomizing plate to generate high-frequency vibration, and then the high-frequency vibration of the atomizing plate disperses the liquid matrix into tiny droplets to form an aerosol.

[0043] The liquid guiding component may include flexible fibers, such as cotton fibers, non-woven fabrics, fiberglass ropes, etc., or porous materials with microporous structures, such as porous ceramics. When the atomizing component adopts a heating atomization method, the heating element may be combined with the liquid guiding component by means of printing, deposition, sintering or physical assembly, or wrapped around the liquid guiding component.

[0044] Please continue reading. Figure 1The receiver 20 also includes a first receiving cavity 22 for receiving the external filter 40. Similarly, the first receiving cavity 22 has a first opening 221 for providing an inlet for the external filter 40 to enter the first receiving cavity 22. The electronic atomizing device also includes an air guide tube 30 for connecting to the receiver 20. After the air guide tube 30 and the receiver 20 are connected, one end of the air guide tube 30 communicates with the first air outlet 11. When the first receiving cavity 22 receives the external filter 40, the other end of the air guide tube 30 can be inserted into the external filter 40, thereby guiding the aerosol generated after atomization to the external filter 40 for filtration.

[0045] The receiver 20 is also provided with a second air outlet 24. The electronic atomizing device 100 also includes a suction tube 50 connected to the second air outlet 24. The filtered aerosol flows further to the second air outlet 24, and the user can inhale the filtered aerosol by sucking through the suction tube 50.

[0046] In some embodiments, the electronic atomizing device 100 may not include the suction tube 50, and the user may directly inhale through the second air outlet 24. The shape of the second air outlet 24 only needs to be designed to facilitate inhalation by the user, for example, the second air outlet 24 can be designed as a mouthpiece.

[0047] The first receiving cavity 22 has a circular cross-section and an inner diameter of 51mm to 57mm, or an inner diameter of 62mm to 68mm. Thus, the first receiving cavity 22 can be used to receive mainstream aluminum cans on the market, so that the aluminum can can be used as an external filter 40 to filter aerosols.

[0048] For example, the outer diameter of mainstream aluminum cans on the market, such as 500 ml, 355 ml, and 330 ml, is typically in the range of 62 mm to 68 mm; while for smaller capacity aluminum cans, such as 250 ml and 200 ml, the outer diameter is typically in the range of 51 mm to 57 mm. Therefore, when a user needs to filter aerosols, they can place an aluminum can of the above dimensions into the first receiving chamber 22 and insert the air guide tube 30 into the aluminum can 40. The air guide tube 30 then guides the aerosol into the liquid inside the aluminum can 40, thereby using the liquid in the aluminum can 40 to filter the aerosol. Users do not need to carry a dedicated filtering device; they can directly use the liquid inside mainstream aluminum cans on the market for filtration, making it convenient for users to carry the electronic atomizing device 100.

[0049] In the above embodiments, the atomizer 10 is removably received in the second receiving chamber 21. Therefore, when the liquid matrix in the atomizer 10 is depleted, the user can remove the atomizer 10 from the second receiving chamber 21 and replace it with a new atomizer 10. In some embodiments, the atomizer 10 and the receiver 20 can also be integrated, meaning the user cannot separately place or remove the atomizer 10 from the receiver 20. In this case, a liquid inlet (not shown) can be provided on the electronic atomizing device 100. When the liquid matrix in the storage chamber is depleted, the liquid matrix can be re-injected into the storage chamber through this liquid inlet.

[0050] In some embodiments, such as Figure 1 As shown, the atomizer 10 includes a mouthpiece 13 for the user to inhale, and a first air outlet 11 is provided on the mouthpiece 13, so the user can also use the atomizer 10 alone for inhalation.

[0051] In some embodiments, the air tube 30 and the receiver 20 are detachably connected. When the user does not need to use the electronic atomizing device 100, the air tube 30 can be detached and stored to avoid the air tube 30 being exposed and contaminated. When the user needs to use the electronic atomizing device, the user can connect the air tube 30 and the receiver 20.

[0052] In some embodiments, such as Figure 2 As shown, when the atomizer 10 receives the atomizer into the second receiving chamber 21, the first air outlet 11 faces the first opening 221 of the first receiving chamber 22, so that the first air outlet 11 is closer to the air guide tube 30, and the aerosol emitted by the atomizer 10 can quickly enter the air guide tube 30.

[0053] In some embodiments, such as Figure 1 and Figure 3 As shown, the second opening 211 of the second receiving cavity 21 and the first opening 221 of the first receiving cavity 22 are arranged opposite to each other along the length of the electronic atomizing device 100. Thus, the user can first invert the atomizer 10 and then insert the atomizer 10 into the second receiving cavity 21, so that the first air outlet 11 of the atomizer 10 faces the first opening 221 of the first receiving cavity 22.

[0054] In some embodiments, such as Figure 2 As shown, a first soft rubber component 25 is also provided in the first receiving cavity 22. The first soft rubber component 25 can be any of silicone, rubber or latex. When the can 40 is inserted into the first receiving cavity 22, the can 40 can be held in the first receiving cavity 22 by the interference fit with the first soft rubber component 25, thereby fixing the can. On the other hand, the interference fit also makes it easy to remove the can 40.

[0055] In some embodiments, such as Figure 2 and Figure 3 As shown, the first soft rubber part 25 also has a retaining portion 251, which defines a retaining chamber (not shown). The retaining chamber is used to retain the air guide tube 30, thereby fixing the air guide tube 30. The air guide tube 30 can be made of a rigid material, such as stainless steel or ceramic. Furthermore, the air guide tube 30 and the retaining chamber can be fixed by an interference fit, which also facilitates the user's disassembly or installation of the air guide tube 30. The first soft rubber part 25 is also provided with a first vent hole (not shown), which connects the retaining chamber and the first air outlet 11. After the aerosol escapes from the first air outlet 11, it can flow through the first vent hole into the retaining chamber and enter the air guide tube 30 in the retaining chamber.

[0056] In some embodiments, a first vent is formed at the top of the retaining portion 251 to further shorten the distance that aerosols travel into the venting tube 30.

[0057] In some embodiments, such as Figure 3 As shown, the receiving device 20 includes a first housing 28 and a second housing 27. A second receiving cavity 21 is disposed in the first housing 28, and a first receiving cavity 22 is disposed in the second housing 27. The first housing 28 and the second housing 27 are detachably connected to facilitate cleaning of the second receiving cavity 21 and the first receiving cavity 22.

[0058] In some embodiments, such as Figure 3 As shown, the receiver 20 also includes a first cover 29 for covering the second opening 211 and a second cover 26 for covering the first opening 221. When the user does not need the electronic atomizing device, the first cover 29 can be placed on the second opening 211 to prevent dust in the air from entering the second receiving cavity 21, and the second cover 26 can be placed on the first opening 221 to prevent dust in the air from entering the first receiving cavity 22.

[0059] In some embodiments, such as Figure 2 As shown, the first soft rubber component 25 also includes a second vent 252, which connects the first receiving cavity 22 and the second air outlet 24. After the aerosol is filtered in the can 40, it escapes from the opening of the can 40, then enters the first receiving cavity 22, flows through the second vent 252 to the second air outlet 24, and finally flows into the suction tube 50 from the second air outlet 24. The user can inhale the filtered aerosol by sucking it in the suction tube 50.

[0060] It should be noted that the interference fit between the first soft rubber part 25 and the can not only hold the can 40 in place, but also, under the action of the interference fit, the first soft rubber part 25 tightly covers the outside of the can, thus playing a sealing role and preventing leakage of filtered aerosol.

[0061] In some embodiments, such as Figure 2 and Figure 3 As shown, the receiving component 20 also includes a second soft rubber component 23 disposed in the first receiving cavity 22. The second soft rubber component 23 can also be any of silicone, rubber or latex. The second soft rubber component 23 is provided with a insertion groove 231. When the atomizer 10 is received into the second receiving cavity 21, the first air outlet 11 of the atomizer 10 can be inserted into the insertion groove 231, thereby achieving a seal through an interference fit to prevent leakage of aerosol escaping from the first air outlet 11.

[0062] In some embodiments, such as Figure 4 As shown, the inner wall of the first receiving cavity 22 has a stepped structure 222, which divides the first receiving cavity 22 into a first section 22a and a second section 22b arranged sequentially along the direction of receiving the can 40. Figure 4 It can be seen that the inner diameter of the first section 22a is larger than that of the second section 22b, and the first section 22a is closer to the first opening 221 than the second section 22b. Therefore, the inner diameter of the first section 22a can be set in the range of 62mm to 68mm to receive mainstream capacity cans such as 500ml, 355ml, and 330ml currently on the market, while the inner diameter of the second section 22b can be set in the range of 51mm to 57mm to receive smaller capacity cans such as 250ml and 200ml. Thus, the electronic atomizing device 100 can not only use mainstream capacity cans such as 500ml, 355ml, and 330ml for filtration, but also smaller capacity cans such as 250ml and 200ml for filtration.

[0063] It is easy to understand that in some embodiments, more stepped structures 222 can be provided on the inner wall of the first receiving cavity 22, thereby dividing the first receiving cavity 222 into more sections with different inner diameters to receive more sizes of aluminum cans 40.

[0064] In some embodiments, it is not necessary to provide the first soft rubber part 25 in the first receiving cavity 22 to hold the can 40. Instead, the second shell 27 forming the first receiving cavity 22 can be made of soft rubber material such as silicone, rubber or latex. Then, when the can 40 is inserted into the first receiving cavity 22, the second shell 27 can wrap the can 40 tightly and keep the can 40 in the first receiving cavity 22.

[0065] In some embodiments, such as Figure 1 and Figure 3 As shown, the housing of the atomizer 10 includes a first transparent portion 12, and the housing of the electronic atomizing device 100 includes a second transparent portion 281 corresponding to the first transparent portion 12. When the atomizer 10 is received in the second receiving cavity 21, the liquid storage cavity in the atomizer 10 can be observed through the first transparent portion 12 and the second transparent portion 281, which makes it easier for the user to observe the remaining liquid in the liquid storage cavity so that the user can replace the atomizer 10 in time when the remaining liquid is insufficient.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them; under the concept of this application, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of this application as described above, which are not provided in detail for the sake of brevity; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
