Description

Technical Field

[0001] The utility model relates to the technical field of atomization devices, in particular to an atomization component, an atomizer and an electronic atomization device. Background Art

[0002] Refer to Figure 1 , the existing atomizer includes:

[0003] An atomization housing 1, the atomization housing 1 includes a liquid storage cavity 101 for storing an aerosol matrix and an aerosol outlet 102 communicating with the external space;

[0004] An atomization core 201, the atomization core 201 is located inside the atomization housing 1, a liquid inlet 2011 communicating with the liquid storage cavity 101 is arranged at the side position of the atomization core 201, and an air outlet communicating with the aerosol outlet 102 is arranged at the top position.

[0005] Specifically, the aerosol matrix in the liquid storage cavity 101 enters the atomization core 201 through the liquid inlet 2011. After the atomization core 201 atomizes the aerosol matrix into aerosol, it is sent out of the atomizer through the aerosol outlet 102. In order to facilitate the atomization core 201 to still normally obtain the aerosol matrix for atomization when the liquid level in the liquid storage cavity 101 is low, the liquid inlet 2011 is usually arranged at the lower part of the atomization core 201, as close as possible to the bottom of the liquid storage cavity 101.

[0006] However, setting the liquid inlet 2011 at the lower part of the atomization core 201 will have the following problems:

[0007] When the liquid storage cavity 101 is filled with the aerosol matrix, the liquid level of the aerosol matrix in the liquid storage cavity 101 is relatively high, and the pressure at the liquid inlet 2011 is relatively large. Under the action of hydraulic pressure, the amount of the aerosol matrix sent into the atomization core 201 is also relatively large, which is likely to cause problems such as insufficient aerosol atomization or liquid dripping from the atomization core downward.

[0008] Therefore, it is necessary to improve the existing atomizer to solve the problem that the liquid inlet amount of the atomization core is too large due to the action of hydraulic pressure.

[0009] The above information disclosed in this background part is only included to enhance the understanding of the background of the present disclosure, and thus may include information that does not form the prior art already known to those of ordinary skill in the art at present. Summary of the Utility Model

[0015] A plurality of longitudinal liquid guiding parts, one end of each longitudinal liquid guiding part is connected to the transverse liquid guiding part, and the other end extends downward relative to the transverse liquid guiding part.

[0016] As an optional implementation manner, it further includes an atomization bracket, and both the atomization core and the liquid absorption assembly are installed and fixed on the atomization bracket.

[0017] As an optional implementation manner, the atomization bracket includes a placement plate for placing the transverse liquid guiding part, and a plurality of guiding columns fixedly arranged at the bottom of the placement plate;

[0018] Wherein, one guiding column is correspondingly arranged for each longitudinal liquid guiding part, and the guiding column is provided with a longitudinal through groove for the corresponding longitudinal liquid guiding part to pass through.

[0019] As an optional implementation manner, a partition plate is connected to the bottom of each guiding column.

[0020] As an optional implementation manner, the placement plate is provided with a positioning groove for the lower end of the atomization core to be inserted.

[0021] As an optional implementation manner, the liquid inlet is located on the side of the atomization core and is attached to the hole wall of the inserting core hole.

[0022] As an optional implementation manner, the distances from each longitudinal liquid guiding part to the atomization core are equal.

[0023] On the other hand, an atomizer is provided, which includes an atomization housing provided with a liquid storage cavity, and the atomization assembly located in the atomization housing;

[0024] Wherein, the atomization core of the atomization assembly is located in the upper part of the liquid storage cavity.

[0025] On yet another hand, an electronic atomization device is provided, which includes the atomizer and a battery assembly electrically connected to the atomizer.

[0055] The electronic atomization device can be used as a humidifier in the field of household appliances. In winter in the north, due to the dry air caused by heating, the electronic atomization device becomes an important household item to increase indoor humidity and improve living comfort;

[0056] Alternatively, the electronic atomization device can also be used as an e-cigarette atomizer in the consumer market, generating aerosol particles by heating e-liquid to mimic the smoke effect after traditional tobacco combustion.

[0057] It should be noted that the electronic atomization device in the present utility model is not limited to the specific applications mentioned above. The specific applications mentioned above are only partial examples of the many uses of the electronic atomization device of the present utility model and do not constitute a specific limitation on the protection scope.

[0058] The following will introduce the power supply housing, battery assembly, and electronic atomization device provided by the present utility model in conjunction with specific drawings.

[0059] The electronic atomization device provided in this embodiment includes an atomizer and a battery assembly electrically connected to the atomizer. Refer to Figure 2 , the atomizer includes an atomization housing 1 provided with a liquid storage cavity 101 and an atomization assembly 2 located inside the atomization housing 1.

[0060] In this embodiment, the battery assembly is disposed inside the atomization housing 1. In some other embodiments, the battery assembly can also be disposed outside the atomization housing 1 and detachably electrically connected to the atomization housing 1 to supply power to the atomization assembly 2.

[0061] In this embodiment, refer to Figures 2 to 4, the atomization assembly 2 includes an atomization core 201 provided with a liquid inlet 2011, a liquid absorption assembly 202 covering the liquid inlet 2011, and an atomization bracket 203 for installing and fixing the atomization core 201 and the liquid absorption assembly 202; wherein, the atomization core 201 of the atomization assembly 2 is located in the upper part of the liquid storage cavity 101, and the liquid absorption assembly 202 is used to transport the aerosol matrix from bottom to top to the liquid inlet 2011.

[0062] For the atomization assembly 2, atomizer and electronic atomization device provided in this embodiment, since the liquid absorption assembly 202 can transport the aerosol matrix from bottom to top to the liquid inlet 2011 of the atomization core 201, when the atomization assembly 2 is installed in the liquid storage cavity 101 of the atomization housing 1, the atomization core 201 can be arranged in the upper part of the liquid storage cavity 101, thereby avoiding the occurrence of excessive pressure caused by the low position of the liquid inlet 2011, and further solving the problem that the atomization core 201 is prone to excessive liquid inlet due to hydraulic action.

[0063] As an optional implementation manner, the liquid absorption assembly 202 includes a transverse liquid guiding part 2021 and a plurality of longitudinal liquid guiding parts 2022. The transverse liquid guiding part 2021 is provided with an insertion hole 2021a for the atomization core 201 to pass through; specifically, the liquid inlet 2011 is located on the side of the atomization core 201 and is attached to the hole wall of the insertion hole 2021a. One end of each longitudinal liquid guiding part 2022 is connected to the transverse liquid guiding part 2021, and the other end extends downward relative to the transverse liquid guiding part 2021 to the bottom of the liquid storage cavity 101.

[0064] Correspondingly, the atomization bracket 203 includes a placement plate 2031 for placing the transverse liquid guiding part 2021, a plurality of guiding columns 2032 fixed to the bottom of the placement plate 2031, and a partition plate 2033 fixed to the bottom of each guiding column 2032. Wherein, one guiding column 2032 is correspondingly arranged for each longitudinal liquid guiding part 2022, and the guiding column 2032 is provided with a longitudinal through groove for the corresponding longitudinal liquid guiding part 2022 to pass through. Further, the placement plate 2031 is provided with a positioning groove 2031a for the lower end of the atomization core 201 to be inserted. When the atomization core 201 is inserted into the positioning groove 2031a, reliable positioning can be achieved.

[0065] In this embodiment, the atomization bracket 203 is made of PCTG material. Specifically, PCTG is a highly transparent copolyester material, which has excellent food hygiene and flame retardancy, and also has chemical resistance, which can effectively avoid the corrosion of the aerosol matrix and ensure the service life. Further, the placement plate 2031, each guiding column 2032, and the partition plate 2033 in the atomization bracket 203 are an integrally injection-molded structure, which saves the assembly process and improves production efficiency.

[0066] The partition plate 2033 divides the liquid storage cavity 101 into an upper cavity and a lower cavity. The upper cavity is mainly used to place the atomization core 201, and the lower cavity is mainly used to store the aerosol matrix. Since the position of the atomization core 201 is relatively high, usually, the aerosol matrix cannot directly submerge the liquid inlet 2011 of the atomization core 201. Even if it can be submerged, the distance from the liquid inlet 2011 to the liquid level of the aerosol matrix is relatively short, so the pressure at the liquid inlet 2011 will not be too high.

[0067] When the liquid level of the aerosol matrix is lower than the horizontal liquid guiding part 2021 of the atomization core 201, since both the vertical liquid guiding part 2022 and the horizontal liquid guiding part 2021 are liquid absorbing structures that can adsorb the aerosol matrix, the vertical liquid guiding part 2022 will transport the aerosol matrix in the lower cavity upward to the horizontal liquid guiding part 2021, and then the horizontal liquid guiding part 2021 will transport it to the liquid inlet 2011 of the atomization core 201. Thus, the aerosol matrix can be transported upward from the bottom to the liquid inlet 2011 of the atomization core 201 in the low liquid level state.

[0068] As an optional implementation manner, the distances from each of the vertical liquid guiding parts 2022 to the atomization core 201 are equal to ensure the uniformity of the liquid supply speed to the atomization core 201 in all directions.

[0069] In this embodiment, the liquid absorbing component 202 is made of a highly water-absorbing material. The highly water-absorbing material is also called a super absorbent, which can absorb water at least hundreds of times its own weight. Common materials include polyurethane sponge, cotton, toilet paper, etc. These materials are widely used in daily life and can absorb water up to hundreds of times their own weight. When used as the liquid absorbing component 202, all the aerosol matrix in the lower cavity can be transported upward to the horizontal liquid guiding part 2021 and finally supplied to the atomization core 201, and the atomization core 201 atomizes the aerosol matrix.

[0070] Of course, in some other embodiments, the liquid absorbing component 202 can also be made of a high molecular weight water-absorbing material. The high molecular weight water-absorbing material usually realizes water absorption through the principle of high-concentration hydrophilic groups and molecular sieves. Among them, polyvinyl alcohol, sodium polyacrylate, and potassium polyacrylate are common high molecular weight water-absorbing materials. These materials can absorb water repeatedly. When used as the liquid absorbing component 202, the service life of the electronic atomization device can be effectively extended.

[0071] Alternatively, the liquid absorption component 2 can also be made of superabsorbent resin. Superabsorbent resin is a polymer with a certain degree of cross-linking, which can quickly absorb hundreds of times its own weight of water to form a gel. Polyacrylate, starch acrylate polymer, starch-acrylonitrile graft copolymer, etc. can all be used as superabsorbent resin. Such materials are used in the paper industry for diapers, sanitary napkins, napkins, etc. When used as the liquid absorption component 202, it can accelerate the liquid delivery speed of the aerosol matrix from the lower chamber to the atomization core 201, ensuring the timeliness of liquid supply.

[0072] In this embodiment, since the entire lower chamber is used to store the aerosol matrix, a liquid injection port can be provided on the bottom surface of the atomization housing 1, and a sealing plug is provided at the liquid injection port. When it is necessary to inject the aerosol matrix, the atomization housing 1 needs to be inverted up and down first, then the sealing plug is opened, and then the aerosol matrix is injected into the lower chamber through the liquid injection port. Finally, the sealing plug is plugged back into the liquid injection port. Such a structural design is conducive to maximizing the utilization of the volume of the lower chamber and storing as much aerosol matrix as possible.

[0073] In this embodiment, the horizontal liquid guiding part 2011 and the vertical liquid guiding part 2022 are detachable structures. Specifically, a plurality of jacks are provided on the horizontal liquid guiding part 2011, and each vertical liquid guiding part 2022 can be detachably inserted into one of the jacks for convenient disassembly, transportation and assembly. In some other embodiments, the horizontal liquid guiding part 2011 and the vertical liquid guiding part 2022 can also be integrally formed structures, which saves the assembly steps and improves the production efficiency. The present utility model does not make any limitation in this regard.

[0074] In summary, the atomization component 2, atomizer and electronic atomization device provided by this embodiment have the following advantages:

[0075] ① The atomization core 201 is arranged at the upper part of the liquid storage chamber 101, and the aerosol matrix is transported from the bottom up to the liquid inlet 2011 of the atomization core 201 through the liquid absorption component 202, thereby avoiding the occurrence of excessive pressure caused by the low position of the liquid inlet 2011, and further solving the problem that the atomization core 201 is prone to excessive liquid inlet due to hydraulic action;

[0076] ② The atomization core 201, the liquid absorption component 202 and the atomization bracket 203 can be first assembled into an integral body and then placed into the liquid storage chamber 101, which is convenient for assembly and conducive to improving production efficiency;

[0077] ③ The distances from each vertical liquid guiding part 2022 to the atomization core 201 are equal, which is conducive to ensuring the uniformity of the liquid delivery speed to the atomization core 201 in all directions.
