Detailed implementation manners

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0033] In the description of the present application, the meaning of "a plurality of" is at least two, for example, two, three, etc., unless otherwise specifically defined. In the present application, unless otherwise clearly specified and defined, terms such as "installed", "connected", "joined", "fixed", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be directly connected, or indirectly connected through an intermediate medium, and can be the connection inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to specific circumstances.

[0034] In the present application, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or simply means that the first feature has a lower horizontal height than the second feature.

[0035] In the description of the present application, it should be understood that the orientation or positional relationship (if any) indicated by terms such as "inside", "outside", "above", "bottom", "front", "rear", etc. is based on the Figure 1 orientation or positional relationship shown in the attached drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or component 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.

[0036] It should also be noted that in the embodiments of the present application, the same reference numerals are used to represent the same component or the same part. For the same parts in the embodiments of the present application, only one of the parts or components may be marked with a reference numeral in the figure. It should be understood that the reference numerals are equally applicable to other identical parts or components.

[0037] An electronic atomization device generally includes a power supply component and an atomizer. The power supply component is used to supply power to the atomizer, and the atomizer is used to heat and atomize an atomization medium to form an aerosol after being powered on. The atomizer is a disposable part, and the power supply component is a recyclable part. At present, the power supply component and the atomizer are generally connected by magnetic adsorption. In addition, the power supply component is provided with a spring pin, and the atomizer is provided with a thimble. The spring pin and the thimble are elastically contacted to form an electrical connection between the power supply component and the atomizer, and the thimble supports a heating element in the atomization chamber to realize the installation and positioning of the heating element in the atomizer. However, since a plurality of magnets, a plurality of spring pins and a plurality of thimbles need to be provided, the cost of the atomizer is high, which is not conducive to the disposable design of the atomizer, and at the same time, the cost of the entire electronic atomization device is also high.

[0038] To solve the above problems, the embodiments of the present application provide an atomizer 100 and an electronic atomization device. By forming a support portion 121 on the lower atomization seat 120, the heating element 130 is supported by the support portion 121 to realize the installation and positioning of the heating element 130 in the atomizer 100, so that the design of the thimble can be cancelled; at the same time, by forming a first connection structure 122 detachably connected to the power supply component 200 on the lower atomization seat 120, the design of the magnet can be cancelled, the structure of the entire atomizer 100 is simplified, which is conducive to the disposable design of the atomizer 100, reduces the cost of the atomizer 100, and at the same time reduces the cost of the entire electronic atomization device.

[0039] Please refer to Figure 1 , the embodiments of the present application provide an electronic atomization device, including an atomizer 100 and a power supply component 200. The power supply component 200 is mechanically connected to the atomizer 100 and electrically connected to the atomizer 100. The power supply component 200 is used to supply power to the atomizer 100, and the atomizer 100 is used to atomize an atomization medium into aerosol particles and deliver the generated aerosol particles to the mouth of a smoker.

[0040] Please refer to Figures 2 to 6 , and now the atomizer 100 provided by the embodiments of the present application will be described.

[0041] The atomizer 100 includes an upper atomization seat 110, a lower atomization seat 120 and a heating element 130. The upper atomization seat 110 and the lower atomization seat 120 are connected to each other and enclose to form an atomization chamber 150. The heating element 130 is installed in the atomization chamber 150. The lower atomization seat 120 is formed with a support portion 121, and the heating element 130 is supported on the support portion 121; a first connection structure 122 is provided on the lower atomization seat 120, and the first connection structure 122 is used to form a detachable connection with the power supply component 200.

[0042] Among them, the heating element 130 is horizontally installed in the atomization chamber 150. Horizontally refers to the horizontal direction when the atomizer 100 is placed vertically, and vertically refers to the vertical direction when the atomizer 100 is placed vertically.

[0043] For the atomizer 100 provided in the embodiment of the present application, by horizontally installing the heating element 130 in the atomization chamber 150 and forming a supporting portion 121 on the lower atomization base 120, the heating element 130 is supported on the supporting portion 121. With such a setting, the thimble installed in the lower atomization base 120 for supporting the heating element 130 can be cancelled, so that the electrode post 250 in the power supply assembly 200 can directly extend into the atomization chamber 150 to be electrically connected to the heating element 130. At the same time, by providing a first connection structure 122 on the lower atomization base 120, a detachable connection is formed with the power supply assembly 200 through the first connection structure 122, and there is no need to provide magnets on the lower atomization base 120 and the power supply assembly 200 to realize the connection between the lower atomization base 120 and the power supply assembly 200. To sum up, by forming the supporting portion 121 and the first connection structure 122 on the lower atomization base 120 in the present application, the thimble and the magnet in the atomizer 100 can be cancelled, the structure of the atomizer 100 is simplified, the structural cost and assembly cost of the atomizer 100 are reduced, which is beneficial to the disposable use design of the atomizer 100, and at the same time, the cost of the entire electronic atomization device is also reduced.

[0044] In one embodiment, please refer to Figure 3 、 Figure 7 and Figure 8 The heating element 130 has a liquid inlet surface 131 and a heating surface 132 arranged oppositely along the vertical direction. The heating surface 132 is arranged downward, and the supporting portion 121 abuts against the heating surface 132. It can be understood that in other embodiments of the present application, when the heating surface 132 of the heating element 130 is arranged upward, the supporting portion 121 abuts against the liquid inlet surface 131 of the heating element 130. In addition, when the heating element 130 is arranged vertically, the supporting portion 121 abuts against the surface of the heating element 130 other than the liquid inlet surface 131 and the heating surface 132.

[0045] In one embodiment, please refer to Figure 2 、 Figure 7 and Figure 8, the lower atomizing base 120 is formed with a plurality of supporting portions 121, and each supporting portion 121 abuts against the heating surface 132 of the heating element 130 and is away from the edge position of the heating film 133. Among them, since the heating element 130 will generate heat after being energized, and the lower atomizing base 120 is usually made of a plastic material, the plastic material is easily softened after being heated, resulting in the unstable structure of the lower atomizing base 120, and the connection between the lower atomizing base 120 and the heating element 130 and the lower atomizing base 120 and the power supply assembly 200 is unstable. In this embodiment, by abutting the supporting portion 121 against the edge position of the heating element 130 away from the heating film 133, that is, making the supporting portion 121 abut against the position with relatively lower heat on the heating element 130, the influence of the heat of the heating element 130 on the lower atomizing base 120 is reduced; at the same time, through the arrangement of the plurality of supporting portions 121, the lower atomizing base 120 and the heating element 130 are supported at multiple points, so that the contact area between the two can be reduced as much as possible on the basis of ensuring the supporting strength, thereby reducing the influence of the heating element 130 on the lower atomizing base 120.

[0046] Specifically, the heating film 133 is arranged on the heating surface 132 of the heating element 130. The heating element 130 has a first end 134 and a second end 135 arranged oppositely along the first direction X. The heating film 133 is arranged between the first end 134 and the second end 135 of the heating element 130 and extends in a bent manner along the first direction X. A part of the supporting portion 121 abuts against the first end 134 of the heating element 130, and another part of the supporting portion 121 abuts against the second end 135 of the heating element 130. Such an arrangement can make the supporting portion 121 as far away from the heating film 133 as possible. It can be understood that in other embodiments of the present application, when the size of the heating element 130 along the second direction Y is also large enough, the supporting portion 121 can also be abutted against the edge of the heating element 130 along the second direction Y, where the first direction X and the second direction Y are mutually perpendicular horizontal directions, and no unique limitation is made here.

[0047] In one embodiment, please refer to Figure 3 , the heating element 130 abuts between the supporting portion 121 and the upper atomizing base 110, and the upper atomizing base 110 is made of an elastic material. In this embodiment, the installation and positioning of the heating element 130 are jointly realized by the supporting portion 121 and the upper atomizing base 110. At the same time, since the upper atomizing base 110 is made of an elastic material, the upper atomizing base 110 has elasticity, so that the heating element 130 and the upper atomizing base 110 are elastically abutted, improving the connection sealing performance between the heating element 130 and the upper atomizing base 110. At the same time, when the electrode post 250 of the power supply assembly 200 is inserted into the atomizing cavity 150 to abut against the heating element 130, the electrode post 250 and the heating element 130 are also elastically abutted, ensuring the connection stability and reliability between the electrode post 250 and the heating element 130.

[0048] Optionally, the upper atomization seat 110 can be made of silica gel, rubber or other elastic materials, so that the upper atomization seat 110 has a sealing effect.

[0049] In one embodiment, please refer to Figure 2 , Figure 3 , Figure 6 , Figure 9 and Figure 10 , the upper atomization seat 110 is formed with an air outlet 111; the atomizer 100 further includes a main housing 140, the main housing 140 includes an inner tube 141 and an outer tube 142, the inner tube 141 is formed with a gas guiding channel 144, and the outer tube 142 and the inner tube 141 enclose a liquid storage cavity 145; the outer tube 142 is sealingly connected to the outer peripheral wall of the upper atomization seat 110, and the inner tube 141 is sealingly connected to the inner peripheral wall of the air outlet 111. In this embodiment, through the sealing connection of the upper atomization seat 110 with the outer tube 142 and the inner tube 141 respectively, the first seal of the atomizer 100 is realized, ensuring that the atomization medium in the liquid storage cavity 145 can only flow down to the heating element 130 from the liquid storage cavity 145 to be heated and atomized by the heating element 130 to form an aerosol. In addition, in this embodiment, by directly making the upper atomization seat 110 of an elastic material, directly forming a sealing connection between the upper atomization seat 110 and the main housing 140, and directly elastically abutting the upper atomization seat 110 against the heating element 130, the design of installing atomization seat sealing silica gel or heating element sealing silica gel on the upper atomization seat 110 can be reduced, simplifying the structure of the atomizer 100 and reducing the cost of the atomizer 100.

[0050] Specifically, please refer to Figure 2 , the top end of the inner tube 141 and the top end of the outer tube 142 are integrally connected to form a mouthpiece 143 for the user to inhale. In addition, in order to prevent external dust from entering the gas guiding channel 144 when the atomizer 100 is not in use, and at the same time to reduce the situation of leakage during storage, a sealing plug 160 is provided at the mouthpiece 143.

[0051] In one embodiment, please refer to Figure 3 , Figure 9 and Figure 10 , the upper atomization seat 110 is formed with at least one liquid outlet 112, the liquid outlet 112 is located below the liquid storage cavity 145 and communicates with the liquid storage cavity 145; the liquid inlet surface 131 of the heating element 130 covers the end surface of the liquid outlet 112 facing away from the liquid storage cavity 145. In this embodiment, by arranging the liquid outlet 112 below the liquid storage cavity 145 and directly covering the liquid inlet surface 131 of the heating element 130 on the end surface of the liquid outlet 112 of the liquid storage cavity 145, the atomization matrix in the liquid storage cavity 145 can flow to the liquid outlet 112 under the action of gravity and directly enter the heating element 130 for atomization, thus being able to improve the problem of poor liquid flow and the burnt and bitter taste caused by air bubbles.

[0052] In one embodiment, referring to Figure 3 , the liquid outlet 112 extends longitudinally, and the atomization medium in the liquid storage cavity 145 can flow longitudinally downward through the liquid outlet 112 to the heating element 130, reducing the flow resistance of the atomization medium and improving the smoothness of the liquid flowing downward of the atomization medium.

[0053] In one embodiment, referring to Figure 3 and Figure 9 , a guiding surface 1121 is further formed on the upper atomization seat 110. The guiding surface 1121 is provided on opposite sides of the liquid outlet 112. The guiding surface 1121 extends obliquely downward from the edge of the upper atomization seat 110 to the liquid outlet 112. The guiding surface 1121 can be an inclined straight surface or an inclined curved surface. The guiding surface 1121 is used to guide the atomization medium at the edge of the upper atomization seat 110 to the liquid outlet 112, so as to improve the effect of the atomization medium flowing to the liquid outlet 112.

[0054] In one embodiment, referring to Figure 3 and Figure 9 , two liquid outlets 112 are formed on the upper atomization seat 110. The two liquid outlets 112 are arranged at intervals along the first direction X. The two liquid outlets 112 respectively correspond to opposite ends of the heating element 130 along the first direction X. The two liquid outlets 112 are respectively used to guide the atomization medium in the liquid storage cavity 145 to opposite ends of the heating element 130 for the heating element 130 to heat and atomize. The aerosol formed by heating and atomization is located in the atomization cavity 150 and is guided to the air guiding channel 144 through the air outlet 111, and is exported through the air guiding channel 144 for the user to inhale.

[0055] In one embodiment, referring to Figure 3 , the air outlet 111 is arranged opposite to the liquid inlet surface 131 of the heating element 130, so that when condensate is generated at the central position of the air guiding channel 144 or the air outlet 111, the condensate can directly drip on the liquid inlet surface 131 of the heating element 130 under the action of gravity and be reheated and atomized by the heating element 130 for utilization, improving the utilization rate of the atomization medium and reducing the cost.

[0056] In one embodiment, referring to Figure 3 and Figure 10 , the upper atomization seat 110 is further formed with a ventilation groove 113. The ventilation groove 113 communicates between the atomization cavity 150 and the air outlet 111. Among them, the arrangement of the ventilation groove 113 enables the atomization cavity 150 to communicate with the air outlet 111, and the aerosol in the atomization cavity 150 can be exported through the air outlet 111.

[0057] In one embodiment, referring to Figure 3 and Figure 10, the heating element 130 extends along the first direction X, the ventilation groove 113 extends along the second direction Y, and the opposite ends of the ventilation groove 113 along the second direction Y bypass the heating element 130 to communicate with the atomization chamber 150. Specifically, the ventilation groove 113 is arranged to cross the heating element 130. Among them, the arrangement of the ventilation groove 113 enables the air outlet 111 to be directly opposite the center position of the liquid inlet surface 131 of the heating element 130 and enables the air outlet 111 to communicate with the atomization chamber 150 on the other side of the heating element 130.

[0058] In one embodiment, please refer to Figure 3 , Figure 7 and Figure 10 , a first capillary channel 1131 extending longitudinally is formed on the inner wall of the ventilation groove 113 along the second direction Y, and a second capillary channel 123 extending longitudinally is formed on the inner wall of the lower atomization base 120 along the first direction X. Among them, the capillary channel refers to a channel that can cause capillary action. In this embodiment, by forming the first capillary channel 1131 on the inner wall of the ventilation groove 113 along the second direction Y, the condensate on the inner walls of the air guiding channel 144 and the air outlet 111 can be guided to the bottom wall of the atomization chamber 150, and the second capillary channel 123 on the inner wall of the lower atomization base 120 can return the condensate in the atomization chamber 150 upward to the heating element 130 through capillary action, so that it can be reused by the heating element 130 for heating and atomization.

[0059] In another embodiment of the present application, first capillary channels 1131 can also be formed on the opposite inner walls of the ventilation groove 113 along the first direction X, so that the condensate can be directly guided to the liquid inlet surface 131 of the heating element 130 for atomization by the first capillary channels 1131 in this part.
