Description

Technical Field

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

[0002] In the related art, for electronic atomization devices, when inhaling aerosol, since the temperature of the ventilation tube wall is much lower than the saturated vapor temperature of the aerosol, condensation will form when the aerosol contacts the ventilation tube wall; among them, for highly viscous atomized liquid, the atomized liquid releases heat to form condensation after forming an aerosol (for example, when it contains media such as propylene glycol and glycerol), the viscosity of which is two orders of magnitude higher than that of water, resulting in the condensation on the ventilation tube wall being difficult to move downward under the action of gravity alone, but firmly adhering to the wall. A large amount of condensation accumulates and causes clogging, thereby causing the electronic atomization device to be unable to be used normally. Utility Model Content

In the description of this utility model, "plurality" or "several" means two or more, unless otherwise specifically defined.

[0036] Example:

[0037] See also Figure 1 and Figure 3 The present invention provides an electronic atomization device, including a power supply 8 and an atomizer. The power supply 8 is used to supply power to the atomizer, and the atomizer is used to heat an atomizing liquid to generate an aerosol. In some specific examples, the connection between the atomizer and the power supply 8 can be a fixed connection or a detachable connection.

[0038] See also Figure 1 and Figure 3 The atomizer includes a body, an atomizer core 1, and a cleaning component. The atomizer core 1 and the cleaning component are both arranged in the body. The body is provided with a liquid storage chamber 22, an air inlet, an atomizing chamber 11, and an air outlet. The atomizer core 1 is arranged in the atomizing chamber 11 and is in liquid communication with the liquid storage chamber 22. The air inlet, the atomizing chamber 11, and the air outlet are connected in sequence. Among them, the cleaning component is used to remove condensed liquid formed in the atomizer air channel. The above-mentioned atomizer air channel can be an air inlet or an air outlet.

[0039] See also Figure 1 and Figure 3 The main body includes an oil cup 2, a suction nozzle 4, and a base 7. The oil cup 2 is provided with a liquid storage chamber 22 and a first air passage 21, which is part of the air outlet. The suction nozzle 4 is connected to one end of the oil cup 2, and the base 7 is connected to the other end of the oil cup 2. The base 7 and the oil cup 2 together form an atomizing chamber 11, which is connected to the first air passage 21. The base 7 is provided with an air inlet that connects the external atmosphere to the atomizing chamber 11.

[0040] It should be noted that, in some embodiments, the liquid storage chamber 22 and the first air channel 21 can be provided on different components. For example, the oil cup 2 includes a cup body and a ventilation tube. The cup body is provided with the liquid storage chamber 22, and the ventilation tube is provided with the first air channel 21. The base 7, the cup body, the atomizer core 1 and the ventilation tube together enclose the atomizer chamber 11.

[0041] See also Figure 1 and Figure 3 In some embodiments, the cleaning component is located between the suction nozzle 4 and the oil cup 2, and the main body further includes a connecting seat 3, which is respectively connected to the suction nozzle 4 and the oil cup 2. The connecting seat 3 is provided with a second air channel 31, and the suction nozzle 4 is provided with a third air channel 41. The second air channel 31 is connected to the first air channel 21 and the third air channel 41 respectively. The first air channel 21, the second air channel 31 and the third air channel 41 constitute the air outlet. Among them, the connecting seat 3 can constitute at least a part of the cleaning part. When the aerosol contacts the inner wall of the air outlet, condensation will be formed. The cleaning component can remove the condensation attached to the inner wall of the air outlet to prevent a large amount of condensation from accumulating and blocking the air outlet. During inhalation, the external atmosphere flows in through the air inlet, and the aerosol generated by the heating of the atomizing core 1 flows into the atomizing chamber 11. The aerosol in the atomizing chamber 11 flows through the first air channel 21, the second air channel 31 and the third air channel 41 in sequence and is inhaled by the user.

[0042] In other embodiments, the cleaning component may also be disposed in the first air passage 21 of the oil cup 2 , in the third air passage 41 of the suction nozzle 4 , or in the air inlet passage of the base 7 .

[0043] See also Figures 1 to 5 The cleaning component includes a carrier, a liquid absorption structure, and a heating structure. The carrier is formed with an air duct, which is the air inlet duct of the atomizer or a part of the air duct. The liquid absorption structure and the heating structure are spaced apart on the carrier along the length of the air duct. The heating structure is used to form a temperature gradient on the inner wall of the air duct. Under the action of the temperature gradient, condensate attached to the inner wall of the air duct moves from the high temperature area to the low temperature area to the liquid absorption structure. That is, under the action of the temperature gradient, the condensate moves in a direction to be absorbed by the liquid absorption structure, thereby reducing the condensate accumulated in the air duct and reducing the occurrence of condensate clogging.

[0044] It should be noted that the carrier can be any component in the atomizer that forms an air inlet or outlet, such as the connecting seat 3, the suction nozzle 4, the oil cup 2, the base 7, etc., wherein, since a large amount of condensate will be formed at the connection between the suction nozzle 4 and the oil cup 2, it is preferably set to be the connecting seat 3. The connecting seat 3 can be made of a material with poor thermal conductivity or no thermal conductivity to avoid the connecting seat 3 absorbing heat and heating up, which is conducive to ensuring that the heating structure forms a temperature gradient on the inner wall of the air duct. When the temperature of the droplets (condensate) at one end is higher than that at the other end, that is, when a temperature gradient is generated, a surface tension gradient will be generated. The surface tension of the hot end is lower than the surface tension of the cold end, so that the droplets move from the hot place to the cold place, that is, the condensate moves from the high temperature area to the low temperature area under the action of the temperature gradient (such as Figure 6 Furthermore, the cleaning component clears the condensate by heating the condensate to a liquefied state, rather than by heating and atomizing the condensate. This allows the cleaning component to be cleaned at a low temperature below the atomization temperature of the condensate, thereby reducing power consumption of the heating structure.

[0045] See also Figure 2 and Figure 4 The liquid absorption structure includes a liquid absorption member 6, which is disposed at the upstream and / or downstream end of the heating structure along the air passage. The downstream end of the heating structure is the end of the connecting base 3 near the suction nozzle 4, and the upstream end of the heating structure is the end of the connecting base 3 near the oil cup 2. The liquid absorption member 6 can absorb and store condensed liquid. For example, the liquid absorption member 6 can be disposed at the end of the connecting base 3 near the oil cup 2, or two liquid absorption members 6 can be provided, one at each end of the connecting base 3. It should be understood that when the atomizer is inverted or upright, the heating structure can drive condensed liquid toward the corresponding liquid absorption member 6, thereby enhancing liquid absorption capacity.

[0046] According to actual needs, the liquid absorbent member 6 can be liquid absorbent cotton, and the liquid absorbent member 6 is annular; an annular mounting groove is provided on the inner wall of the second air duct 31, and the liquid absorbent member 6 is installed in the mounting groove, and the liquid absorbent member 6 and the connecting seat 3 are coaxially arranged, and the inner wall surface of the through hole of the liquid absorbent member 6 is flush with the inner wall surface of the second air duct 31, or the inner wall surface of the through hole of the liquid absorbent member 6 is slightly protruding relative to the inner wall surface of the second air duct 31, which is conducive to the flow of condensate to the liquid absorbent member 6.

[0047] In the embodiment of the present invention, the heating structure includes a heating element 5, which is arranged in an annular shape on the inner wall of the air duct, so that all condensed liquid attached to the inner wall of the air duct can be directed to move under the action of the temperature gradient and be absorbed by the liquid absorbing member 6. The heating element 5 is coaxially arranged with the connecting base 3. The heating element 5 can be provided as one or more heating elements, for example:

[0048] See also Figure 1 and Figure 2In one embodiment, a plurality of heating elements 5 are provided, and the plurality of heating elements 5 are spaced apart along the length of the air passage, thereby forming a temperature gradient on the inner wall of the air passage. For example, the number of heating elements 5 may be two, three, four, five, six, etc. When the number of heating elements 5 is greater than two, the heating elements 5 are spaced apart equally.

[0049] See also Figure 1 and Figure 2 In one specific example, five heating elements 5 are provided, fixed to the inner wall of the second air passage 31 of the connecting base 3. The five heating elements 5 are spaced apart along the length of the second air passage 31, with the first heating element 5 closest to the suction nozzle 4 and the fifth heating element 5 closest to the oil cup 2. When condensate accumulates on the inner surface of the second air passage 31 of the connecting base 3, it is heated sequentially, starting from the first heating element 5 to the fifth heating element 5. The condensate is then rapidly and efficiently moved to the wicking element 6 for absorption, utilizing the capillary effect.

[0050] It should be noted that the moving speed of the droplets (condensate) is related to the temperature of the heating element 5, that is, the temperature gradient of the droplets, and the greater the temperature gradient, the greater the moving speed. Figure 6 As shown in the figure, when the temperature gradient reaches 100°C, it only takes 0.04 seconds for the droplets to move 3.2mm. Moreover, in theory, as long as there is a temperature gradient, the droplets can spontaneously move to the cold area, achieving directional drainage and collection of the condensate. Even a temperature gradient as low as 10°C can achieve directional movement of the droplets, and the directional movement, absorption and storage of the condensate can be completed within 1 second.

[0051] It should be understood that when the electronic atomizer determines that the user has completed puffing and has not been activated again within a certain period of time, it controls the heating element 5 to heat up, thereby starting the condensate removal process. Moreover, because the droplets are directed to move under a temperature gradient as low as 10°C, the temperature resistance requirements for the materials of the connecting base 3, oil cup 2, and nozzle 4 are low, which does not impose a cost burden and is relatively easy to implement.

[0052] In one embodiment, the heating element 5 is provided with a plurality of heating regions having different heating temperatures. The plurality of heating regions are distributed continuously or sequentially along the length of the airway, and the heating temperatures of the plurality of heating regions gradually decrease toward the liquid absorbing structure, thereby forming a temperature gradient on the inner wall of the airway. For example, the plurality of heating regions may be provided with two, three, four, five, or six heating regions, and the heating regions may be distributed continuously or sequentially.

[0053] In a specific example, the heating element 5 is fixed on the inner wall of the second air channel 31 of the connecting seat 3. The heating element 5 is provided with four heating areas with different heating temperatures. The four heating areas are continuously distributed along the length direction of the second air channel 31. Among them, the first heating area is closest to the suction nozzle 4, and the temperature of the first heating area is the highest. The fourth heating area is closest to the oil cup 2, and the temperature of the fourth heating area is the lowest. The condensate can be quickly and directionally moved to the liquid absorption part 6 for absorption by utilizing the thermal capillary effect.

[0054] See also Figure 3 、 Figure 4 and Figure 5 In one embodiment, the heating element 5 is provided with a liquid guide groove 32 on the inner wall of the airway. One end of the liquid guide groove 32 extends to the heating element 5, and the other end extends to contact the liquid absorbing structure. The provision of the liquid guide groove 32 can guide the flow of condensed liquid and, combined with the thermocapillary effect, more quickly guide the condensed liquid into the liquid absorbing member 6. Furthermore, the number of heating elements 5 can be reduced to one, which helps reduce costs. It should be understood that the area on the inner wall of the airway where the heating element 5 is not provided forms a temperature gradient with the area on the inner wall of the airway where the heating element 5 is provided.

[0055] See also Figure 4 and Figure 5 Multiple liquid-guiding grooves 32 are provided, spaced apart along the circumference of the airway. These multiple liquid-guiding grooves 32 can guide the movement of all condensed liquid adhering to the inner wall of the airway. The heating element 5 is provided with multiple heating protrusions 51, spaced apart along the circumference of the airway, with each heating protrusion 51 located between two liquid-guiding grooves 32. This prevents the heating protrusions 51 from blocking the condensed liquid adhering to the inner wall of the airway from flowing into the liquid-guiding grooves 32.

[0056] See also Figure 3 、 Figure 4 and Figure 5 In one specific example, a liquid guide groove 32 is provided on the inner wall of the second air passage 31 of the connecting base 3. The bottom of the liquid guide groove 32 is recessed relative to the inner wall of the third air passage 41 of the suction nozzle 4, facilitating the flow of condensed liquid adhering to the inner wall of the third air passage 41 of the suction nozzle 4 into the liquid guide groove 32. The bottom of the liquid guide groove 32 is also recessed relative to the inner wall of the inner hole of the liquid absorbing member 6, facilitating the flow of condensed liquid in the liquid guide groove 32 into the liquid absorbing member 6. The heating element 5 is fixed to the inner wall of the second air passage 31 of the connecting base 3, and the heating element 5 is provided at the end of the connecting base 3 near the suction nozzle 4. The liquid absorbing member 6 is provided at the end of the connecting base 3 near the oil cup 2.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
