Description

Technical Field

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

[0002] In related technologies, during the suction process, the atomization liquid stored in the electronic atomization device is likely to leak out of the liquid storage chamber under the action of the internal and external pressure difference. When the atomization liquid is a high-viscosity atomization liquid, the atomization liquid leaking out of the liquid storage chamber is difficult to flow back into the liquid storage chamber and is also difficult to be utilized by the atomization core. Repeated pressure actions will form a large amount of accumulated liquid at the bottom of the electronic atomization device, resulting in a low utilization rate of the atomization liquid of the electronic atomization device and easily causing blockage of the air flow channel of the electronic atomization device.

[0034] In the present application, the "top" and "bottom" orientation or positional relationship is based on the orientation or positional relationship shown in the attached Figure 2 drawings. It should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0035] An embodiment of the present application provides an atomizer. Please refer to Figure 1 and Figure 2 , the atomizer includes a housing assembly 10 and an atomization component 20.

[0036] The housing assembly 10 has an air flow channel 10a.

[0037] The atomization component 20 is arranged in the housing assembly 10, and the side of the atomization component 20 close to the air flow channel 10a has an atomization surface 20a.

[0038] Please refer to Figure 9 and Figure 10 , the wall body of the housing assembly 10 located on at least one side of the atomization component 20 has a liquid storage tank 10b, and the atomization component 20 contacts the atomization liquid in the liquid storage tank 10b to transfer the atomization liquid in the liquid storage tank 10b to the atomization surface 20a.

[0039] Another embodiment of the present application provides an electronic atomization device. The electronic atomization device includes a power supply component and the atomizer according to any embodiment of the present application, and the power supply component is electrically connected to the atomizer.

[0040] Specifically, the atomizer can be used to contain atomization liquids such as liquid medicine and e-liquid and atomize them into aerosol for users to inhale.

[0041] The air flow channel 10a is a channel for the air flow flowing into the atomizer. During the operation of the atomizer, after the external air flow flows into the housing assembly 10, it flows along the air flow channel 10a and takes out the aerosol formed by atomizing the atomization assembly 20 for the user to inhale.

[0042] The atomization assembly 20 is used to atomize the atomization liquid to generate aerosol. Its specific structure is not limited. For example, the atomization assembly 20 includes an atomization core. The atomization core is used to heat and atomize the atomization liquid to generate aerosol. Another example is that the atomization assembly 20 further includes a heating element silica gel, and the heating element silica gel is arranged on the top of the atomization core.

[0043] Please refer to Figure 5 and Figure 6 , the atomization surface 20a of the atomization assembly 20 is used to atomize the atomization liquid to form aerosol, and the atomization surface 20a of the atomization assembly 20 is located on the side of the atomization assembly 20 close to the air flow channel 10a. In fact, one end of the atomization assembly 20 with the atomization surface 20a extends to the air flow channel 10a, and the atomization surface 20a faces into the air flow channel 10a, so that the air flow in the air flow channel 10a can pass through the atomization surface 20a, so that the air flow can drive the aerosol formed by atomizing the atomization surface 20a to flow, so as to achieve a better fog output effect.

[0044] Please refer to Figure 7 and Figure 8 , the atomization assembly 20 is located in the housing assembly 10, and a liquid storage tank 10b is formed between the inner wall of the housing assembly 10 and the atomization assembly 20.

[0045] It should be noted that the liquid storage tank 10b can be formed only on the wall corresponding to one side of the atomization assembly 20, or the liquid storage tank 10b can be formed on the walls corresponding to multiple sides of the atomization assembly 20 respectively, or the liquid storage tank 10b can be formed on the walls corresponding to the sides in all directions of the atomization assembly 20.

[0046] During the inhalation process, the atomization liquid will leak out from the liquid storage bin 10c of the housing assembly 10 under the action of the internal and external pressure difference. Among them, at least part of the leaked atomization liquid flows to the liquid storage tank 10b under the action of gravity and can be locked in the liquid storage tank 10b under the action of surface tension.

[0047] During the atomization process of the atomization assembly 20, the atomization assembly 20 can contact with the atomization liquid in the liquid storage tank 10b, so as to absorb the atomization liquid in the liquid storage tank 10b through its own capillary action and transport it to the atomization surface 20a for atomization.

[0048] It should be noted that the atomization assembly 20 is an atomization structure that can absorb the atomization liquid in an unsaturated state and transport the atomization liquid to the atomization surface 20a.

[0049] For example, the atomizing component 20 includes an atomizing core, and the atomizing core is a porous heating body. Thus, under the capillary action of the pores in the porous heating body, the atomizing liquid leaked into the atomizing tank can be absorbed and transmitted to the atomizing surface 20a to be atomized into an aerosol.

[0050] Moreover, the atomizing component 20 should be disposed close to the liquid storage tank 10b. That is to say, the distance between the atomizing component 20 and the liquid storage tank 10b should not be too far. According to the actual situation, the atomizing component 20 can be attached to the tank wall of the liquid storage tank 10b, or there can be a narrow gap between the atomizing component 20 and the tank wall of the liquid storage tank 10b. Among them, the gap between the atomizing component 20 and the liquid storage tank 10b needs to meet the requirement that when the liquid storage tank 10b locks the atomizing liquid, the atomizing component 20 can contact the atomizing liquid and transmit it to the atomizing surface 20a for atomization.

[0051] In the atomizer in the related art, the atomizing liquid is likely to leak out of the liquid storage chamber under the action of the internal and external pressure difference during the suction process, or is likely to leak out of the liquid storage chamber under the working conditions with a large temperature difference between day and night.

[0052] In the atomizer according to the embodiment of the present application, the wall body of the housing assembly 10 located on at least one side of the atomizing component 20 has a liquid storage tank 10b. The atomizing component 20 contacts the atomizing liquid in the liquid storage tank 10b so that the atomizing liquid in the liquid storage tank 10b is transmitted to the atomizing surface 20a. The atomizing liquid leaked into the liquid storage tank 10b under the action of the internal and external pressure difference can be locked in the liquid storage tank 10b under the action of the surface tension. Thus, at least part of the atomizing liquid in the liquid storage tank 10b can contact the atomizing component 20, be absorbed by the atomizing component 20 and transmitted to the atomizing surface 20a to atomize the atomizing liquid into an aerosol. Thus, the atomizing liquid accumulated at the bottom of the electronic atomizing device due to leakage can be reduced, thereby achieving the purpose of reducing liquid accumulation, improving the utilization rate of the atomizing liquid of the electronic atomizing device, and reducing the risk of blockage of the air flow channel 10a of the electronic atomizing device.

[0053] In one embodiment, please refer to Figure 2 and Figure 9 , the housing assembly 10 includes a liquid storage chamber 10c and an installation cavity 10d. The installation cavity 10d is respectively communicated with the liquid storage chamber 10c and the air flow channel 10a. The atomizing component 20 is disposed in the installation cavity 10d to separate the liquid storage chamber 10c and the air flow channel 10a. The communication part between the liquid storage chamber 10c and the installation cavity 10d faces the atomizing component 20. The wall body of the installation cavity 10d located on at least one side of the atomizing component 20 has a liquid storage tank 10b. Thus, the risk of accumulation of the atomizing liquid in the housing assembly 10 can be reduced, and the atomizing effect can be improved.

[0054] Specifically, the liquid storage chamber 10c is an accommodation chamber for storing the atomizing liquid in the housing assembly 10.

[0055] The installation cavity 10d is used to install the atomization component 20, and the atomization component 20 can separate the liquid storage chamber 10c and the air flow channel 10a. That is to say, the atomized liquid in the liquid storage chamber 10c needs to pass through the atomization component 20 to be transmitted to the atomization surface 20a, so as to supply the atomization component 20 to atomize and form an aerosol, and flow with the air flow in the air flow channel 10a.

[0056] The connection between the liquid storage chamber 10c and the installation cavity 10d facing the atomization component 20 means that the opening of the connection between the liquid storage chamber 10c and the installation cavity 10d faces the atomization component 20, so as to facilitate the downward flow of the atomized liquid in the liquid storage chamber 10c to the atomization component 20 under the suction effect.

[0057] Please refer to Figure 5 and Figure 6 The atomized liquid moves from the liquid storage chamber 10c towards the bottom side into the atomization component 20. Under the suction effect, the atomization component 20 transmits the atomized liquid to the side of the atomization surface 20a, so as to facilitate the atomization of the atomized liquid at the atomization surface 20a to form an aerosol, and flow out of the housing assembly 10 with the air flow in the air flow channel 10a.

[0058] In one embodiment, please refer to Figure 3 、 Figure 4 and Figure 9 The liquid storage tank 10b includes a first liquid storage tank 10ba. The atomization component 20 has a first side surface 20b. The first side surface 20b is spaced from the wall of the installation cavity 10d to form a ventilation channel 10e at the interval. One end of the ventilation channel 10e is communicated with the liquid storage chamber 10c, and the other end of the ventilation channel 10e is communicated with the air flow channel 10a. At least one first liquid storage tank 10ba is formed in the ventilation channel 10e. Thus, the atomization component 20 can absorb the atomized liquid leaked at the ventilation channel 10e and transmit it to the atomization surface 20a for atomization, which can reduce the risk of liquid accumulation and improve the utilization rate of the atomized liquid.

[0059] Specifically, the atomized liquid in the liquid storage chamber 10c flows to the atomization component 20 for atomization, which is not realized through the ventilation channel 10e. The ventilation channel 10e is an air intake channel provided for balancing the air pressure between the liquid storage chamber 10c and the outside.

[0060] One end of the ventilation channel 10e is communicated with the liquid storage chamber 10c, and the other end is communicated with the air flow channel 10a. Thus, the atmosphere can be communicated to facilitate the ventilation into the liquid storage chamber 10c. Please refer to Figure 4 Air can enter the liquid storage chamber 10c along the ventilation channel 10e through the ventilation port 10f to balance the air pressure inside and outside the liquid storage chamber 10c, so as to facilitate the downward flow of the liquid.

[0061] In fact, in the related art, during the user's suction process, some of the energy used to heat the atomization component by power supply will be directly or indirectly transferred to the air in the liquid storage chamber. The air expands when heated and the pressure increases. At the same time, the viscosity of the atomizing liquid in the liquid storage chamber also decreases. Under the action of the pressure, the atomizing liquid in the liquid storage chamber will overflow from the ventilation channel or the surface of the atomization component. Among the overflowed atomizing liquid, part of the atomizing liquid will be absorbed by the atomization component for atomization on the atomization surface, while the other part of the atomizing liquid will continue to flow downward under the action of gravity and thus leak through the ventilation channel. When the atomizing liquid is a high-viscosity medium, due to its high viscosity resulting in very poor fluidity, it is difficult for the atomizing liquid to be pushed back into the liquid storage chamber by ventilation in the ventilation channel. Therefore, the leaked liquid storage chamber will continuously increase and finally accumulate at the bottom of the housing assembly.

[0062] Therefore, by providing a first liquid storage tank 10ba in the ventilation channel 10e, the atomizing liquid leaked from the liquid storage chamber 10c through the ventilation channel 10e can be locked in the first liquid storage tank 10ba, and then through contact with the atomization component 20, it can be transmitted by the atomization component 20 to the atomization surface 20a for atomization.

[0063] It should be noted that only one first liquid storage tank 10ba may be formed in the ventilation channel 10e, or multiple first liquid storage tanks 10ba may be formed.

[0064] In one embodiment, please refer to Figure 9 and Figure 10 , a partial area of the wall of the installation cavity 10d protrudes toward the atomization component 20 side to form a plurality of first liquid guiding strips 11. The first liquid guiding strips 11 are arranged at intervals in the ventilation channel 10e and extend along the extending direction of the ventilation channel 10e to form the first liquid storage tank 10ba at intervals. Thus, by providing the first liquid guiding strips 11, the atomizing liquid leaked from the liquid storage chamber 10c into the ventilation channel 10e can be locked in the first liquid storage tank 10ba. On the one hand, it is convenient for part of the atomizing liquid in the first liquid storage tank 10ba to be gradually pushed back into the liquid storage chamber 10c during ventilation to reduce the risk of liquid accumulation. On the other hand, it is also convenient for another part of the atomizing liquid in the first liquid storage tank 10ba to contact the atomization component 20, to be transmitted to the atomization surface 20a, and then be atomized into an aerosol, thereby further reducing the risk of liquid accumulation and improving the utilization rate of the atomizing liquid.

[0065] Specifically, the first liquid storage tank 10ba is formed at intervals between adjacent first liquid guiding strips 11, and the interval therebetween needs to meet the requirement of being able to lock at least part of the atomizing liquid leaked from the liquid storage chamber 10c into the ventilation channel 10e to prevent the atomizing liquid from continuously flowing downward under the action of gravity and accumulating in the bottom area of the housing assembly 10.

[0066] In fact, the first liquid storage tank 10ba also extends along the extension direction of the air exchange passage 10e. Thus, the influence of the first liquid guiding strip 11 on the air exchange effect of the air exchange passage 10e can be reduced.

[0067] In one embodiment, please refer to Figure 2 、 Figure 11 and Figure 12 , the housing assembly 10 includes a housing 12 and a base 13. The housing 12 has a liquid storage chamber 10c and an air flow passage 10a. The base 13 and the housing 12 enclose an installation cavity 10d. The liquid storage tank 10b includes a second liquid storage tank 10bb. A part of the area of the base 13 located in the installation cavity 10d is recessed to form the second liquid storage tank 10bb. At least a part of the bottom surface of the atomization assembly 20 is located on the top side of the second liquid storage tank 10bb. Thus, it is convenient for the atomization assembly 20 to transfer the atomized liquid leaked to the base 13 to the atomization surface 20a for atomization, which can further reduce the risk of liquid accumulation and improve the utilization rate of the atomized liquid.

[0068] In the related art, during the atomization process of the atomizer, the atomized liquid on the atomization surface will form a liquid film around under the action of steam pressure. Since the viscosity of the liquid film is relatively low during heating, it is easy to flow down into the base to form liquid accumulation.

[0069] In this embodiment, at least a part of the base 13 is located on the bottom side of the atomization assembly 20. A second liquid storage tank 10bb is formed on the base 13, and at least a part of the second liquid storage tank 10bb is located on the bottom side of the atomization assembly 20 to lock the atomized liquid leaked to the base 13 under the action of gravity. Furthermore, it is used for the atomization assembly 20 to contact the atomized liquid in the second liquid storage tank 10bb and transfer it to the atomization surface 20a for atomization to form an aerosol.

[0070] In a specific embodiment, please refer to Figure 11 , at least a part of the bottom surface of the atomization assembly 20 is attached to the top end of the second liquid storage tank 10bb. Thus, the possibility of the atomization assembly 20 contacting the atomized liquid locked in the second liquid storage tank 10bb can be increased, and the risk of liquid accumulation can be further reduced.

[0071] It should be noted that it can be that a part of the bottom surface of the atomization assembly 20 is attached to the top end of the second liquid storage tank 10bb, or it can be that the entire bottom surface of the atomization assembly 20 is attached to the top end of the second liquid storage tank 10bb.

[0072] Of course, in other embodiments, there may also be a certain gap between the bottom surface of the atomization assembly 20 and the top end of the second liquid storage tank 10bb.

[0073] In one embodiment, please refer to Figure 11 and Figure 12, the base 13 includes at least one second liquid guiding strip 131. The second liquid guiding strip 131 is disposed in the second liquid storage tank 10bb to divide the second liquid storage tank 10bb into a plurality of sub-tanks. In the projection plane parallel to the bottom surface of the atomization assembly 20, the projection of at least a part of the second liquid guiding strip 131 coincides with the bottom surface projection of the atomization assembly 20. Thereby, the effect of locking the atomization liquid in the area at the bottom side of the atomization assembly 20 of the second liquid storage tank 10bb can be improved, so that it is convenient for the atomization assembly 20 to contact the atomization liquid to transfer it to the atomization surface 20a.

[0074] Specifically, the number of the second liquid guiding strips 131 is not limited. For example, the base 13 may include only one second liquid guiding strip 131, or the base 13 may also include a plurality of second liquid guiding strips 131 arranged at intervals.

[0075] By dividing the second liquid guiding strip 131 into a plurality of sub-tanks, the tank width of the second liquid storage tank 10bb can be reduced, which is convenient for the atomization assembly 20 to contact the atomization liquid in the sub-tanks to absorb and transfer the atomization liquid to the atomization surface 20a.

[0076] A part of the second liquid guiding strip 131 may be located at the bottom side of the atomization assembly 20, and another part extends out of the coverage range of the atomization assembly 20.

[0077] Of course, according to the actual situation, all areas of the second liquid guiding strip 131 may also be located at the bottom side of the atomization assembly 20.

[0078] From the perspective of projection, that is, the projection of at least a part of the second liquid guiding strip 131 coincides with the bottom surface projection of the atomization assembly 20, that is to say, at least a part of the second liquid guiding strip 131 is within the coverage range of the atomization assembly 20.

[0079] In one embodiment, please refer to Figure 11 and Figure 12 , the second liquid storage tank 10bb includes a tank bottom wall having an overflow port 10bc. The overflow ports 10bc are respectively communicated with the air flow channel 10a and the outside, and the side walls of the overflow ports 10bc extend towards the inside of the second liquid storage tank 10bb.

[0080] Specifically, the liquid passing port 10bc is located on the bottom wall of the second liquid storage tank 10bb, and is used to connect the outside and the air flow channel 10a. The side wall of the liquid passing port 10bc extends towards the top side, so as to form a convex step protruding relative to other areas of the bottom wall of the tank. Thus, during the atomization process of the atomizer, even if the atomized liquid leaks from the liquid storage chamber 10c to the base 13, due to the existence of the convex step, more atomized liquid can be stored in the second liquid storage tank 10bb, which can greatly reduce the continuous downward flow of the leaked atomized liquid from the liquid passing port 10bc. At the same time, it is also convenient to lock the atomized liquid in the second liquid storage tank 10bb, so that after the atomization component 20 contacts the atomized liquid, it can absorb and transport it to the atomization surface 20a for atomization, which can further improve the effect of reducing liquid leakage and enhancing the utilization rate of the atomized liquid.

[0081] In one embodiment, please refer to Figure 11 and Figure 12 , the base 13 includes a base body 132 and a base silica gel 133 disposed between the base body 132 and the atomization component 20, and the base silica gel 133 has a second liquid storage tank 10bb. Thus, by providing the base silica gel 133, the sealing effect between the base 13 and the housing 12 can be improved, and at the same time, it is convenient to process and form the second liquid storage tank 10bb.

[0082] In a specific embodiment, the first side surface 20b and the atomization surface 20a are respectively located on opposite sides of the atomization component 20 in the circumferential direction, and the wall bodies of the housing assembly 10 located on the other opposite sides of the atomization component 20 in the circumferential direction also have liquid storage tanks 10b. Thus, liquid storage tanks 10b correspond to other side surfaces of the atomization component 20 except the top surface and the atomization surface 20a, which can further improve the effect of locking the atomized liquid leaked from the liquid storage chamber 10c, thereby further reducing the risk of liquid accumulation.
