DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] In the description of this application, "plurality" means at least two, such as two, three, etc., unless otherwise clearly defined.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0030] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0032] It should also be noted that, in the embodiments of the present application, the same figure mark is used to represent the same component or the same part. For the same parts in the embodiments of the present application, the figure may only mark one of the parts or components as an example. It should be understood that the figure mark also applies to other identical parts or components.

[0033] The electronic atomization device generally includes a battery assembly and an atomizer. The battery assembly is used to power the atomizer, and the atomizer is used to heat the atomization medium and atomize it to form an aerosol after power is turned on. The atomizer includes a heating assembly, which is electrically connected to the battery assembly and is used to heat the atomization medium and atomize it to form an aerosol after power is turned on.

[0034] At present, the heating component in the atomizer is generally electrically connected to the battery component through a metal conductor, that is, the conduction process between the heating component and the battery component passes through the metal conductor. The double conduction leads to increased conduction resistance, a higher conduction risk, and many parts and high cost.

[0035] In order to solve the above problems, the embodiments of the present application provide an atomizer 100 and an electronic atomization device, by directly extending the heating element 112 in the heating component 110 to the outside of the atomizer 100 to be electrically connected to the battery component 200, thereby omitting the setting of the metal conductor, so that the heating component 110 and the battery component 200 can be directly connected, reducing the conduction resistance, reducing the conduction risk, and also reducing the setting of the metal conductor, thereby reducing the cost of the atomizer 100.

[0036] See also Figure 1 and Figure 2 The embodiment of the present application provides an electronic atomization device, including an atomizer 100 and a battery assembly 200. The battery assembly 200 is mechanically connected to the atomizer 100, and the battery assembly 200 is electrically connected to the atomizer 100. The battery assembly 200 is used to power the atomizer 100. The atomizer 100 is used to atomize the atomization medium into aerosol particles and transport the generated aerosol particles to the oral cavity of the smoker.

[0037] Please also read Figures 3 to 6 , the atomizer 100 provided in the embodiment of the present application is now described.

[0038] The atomizer 100 includes an atomizer seat 120 and a heating component 110. The heating component 110 is installed in the atomizer seat 120. The heating component 110 includes a liquid-conducting body 111 and a heating element 112. The heating element 112 is arranged on the surface of the liquid-conducting body 111. The heating element 112 has two connecting ends 1121. The two connecting ends 1121 extend to the outside of the atomizer seat 120 respectively for electrical connection with the battery assembly 200.

[0039] The atomizer seat 120 is used to install the heating component 110, and is used to guide the atomized medium to the heating component 110 so that the heating component 110 heats and atomizes to form an aerosol, and the atomizer seat 120 is also used to guide the formed aerosol out.

[0040] The liquid-conducting body 111 is used to absorb and store the atomized medium. The heating element 112 is disposed on the surface of the liquid-conducting body 111 . The heating element 112 is used to heat the atomized medium stored in the liquid-conducting body 111 and atomize it into an aerosol after being powered on.

[0041] The heating element 112 generally has two connection ends 1121 , which are equivalent to two electrodes. The two connection ends 1121 are used to form an electrical connection with the battery assembly 200 to supply power to the heating element 112 .

[0042] The atomizer 100 provided in the embodiment of the present application directly extends the two connecting ends 1121 of the heating element 112 to the outside of the atomizer seat 120, so that when the battery assembly 200 is mechanically connected to the atomizer 100, the two connecting ends 1121 can directly form an electrical connection with the battery assembly 200, omitting the intermediate metal conductor, so that the heating assembly 110 and the battery assembly 200 can be directly connected, reducing the conduction resistance, reducing the conduction risk, and also reducing the setting of the metal conductor, thereby reducing the cost of the atomizer 100.

[0043] In one embodiment, the liquid-conducting cotton 111 may be oil-conducting cotton, which is wound into a roughly cylindrical shape and absorbs the atomizing medium through the oil-conducting cotton so that the heating element 112 is heated and atomized to form an aerosol. It is understandable that in other embodiments of the present application, the liquid-conducting cotton 111 may also be a porous ceramic, which absorbs and stores the atomizing medium. In addition, the liquid-conducting liquid 111 may also be a multi-layer structure. For example, the liquid-conducting liquid 111 includes a base layer and a liquid-conducting component sleeved on the outside of the base layer. A liquid-conducting channel is formed in the center of the base layer, and a liquid-conducting hole is formed on the side wall of the base layer. The atomizing medium enters the liquid-conducting channel through both ends of the base layer and is guided to the liquid-conducting component through the liquid-conducting hole. The liquid-conducting component guides the atomizing medium to the heating element 112.

[0044] In one embodiment, see Figure 5 , the liquid guiding liquid 111 is disposed transversely in the atomizing seat 120. It can be understood that in other embodiments of the present application, the liquid guiding liquid 111 can also be disposed longitudinally in the atomizing seat 120, which is not the only limitation here.

[0045] Among them, the longitudinal setting here is a direction parallel or approximately parallel to the height direction of the electronic atomization device when the electronic atomization device is placed vertically, and the transverse direction refers to a direction parallel to the longitudinal direction, that is, a roughly horizontal direction when the electronic atomization device is placed vertically.

[0046] In one embodiment, see Figure 7 The heating element 112 is a heating wire wound on the surface of the liquid-conducting body 111. The heating wire has a small diameter, a large length, and a small resistance, which ensures stable conduction between the heating element 112 and the battery assembly 200. It can be understood that in other embodiments of the present application, the heating element 112 can also be a metal sheet structure arranged on the surface of the liquid-conducting body 111 and extending to the outside of the atomizer seat 120, which is not limited here.

[0047] In one embodiment, see Figure 5 and Figure 7 The heating wire is wound around the outer surface of the liquid guiding body 111, and the heating wire directly extends from the outer surface of the liquid guiding body 111 to the outside of the atomizing seat 120. It can be understood that in other embodiments of the present application, the heating body 112 can also extend outward from the inner surface of the liquid guiding body 111, which is not limited here.

[0048] In one embodiment, see Figure 5 Two through holes 124 are formed at the bottom of the atomizer seat 120, and two connecting ends 1121 extend from the two through holes 124 to the outside of the bottom of the atomizer seat 120. By providing two through holes 124 at the bottom of the atomizer seat 120, the two connecting ends 1121 can directly extend downward to the outside of the bottom of the atomizer seat 120, so that when the atomizer 100 and the battery assembly 200 are connected in the longitudinal direction, the two connecting ends 1121 can directly abut against the battery assembly 200 to form an electrical connection.

[0049] In addition, when the liquid-conducting body 111 is disposed transversely in the atomizing seat 120, and the heating element 112 is a heating wire, after the heating wire is wound around the outer wall of the liquid-conducting body 111, the two connecting ends 1121 of the heating wire can extend straightly from the direction tangent to the liquid-conducting body 111 to the bottom of the atomizing seat 120, thereby reducing the risk of poor electrical connection caused by bending and twisting of the heating element 112 in the atomizing seat 120. It can be understood that in other embodiments of the present application, a through hole 124 can also be provided on the side of the atomizing seat 120, and the connecting end 1121 can be extended from the side of the atomizing seat 120 to be electrically connected to the battery assembly 200, which is not the only limitation here.

[0050] In one embodiment, see Figure 5 and Figure 8 , the through hole 124 is at least partially converged from the edge to the middle of one end of the guiding liquid 111 to form a guiding surface 1241 of the guiding connecting section 1123. Among them, the diameter of the heating element 112 is relatively small, and the guiding liquid 111 and the heating element 112 are assembled as a whole. During assembly, the staff needs to ensure that the guiding liquid 111 is assembled in place in the atomizer seat 120, and that the two connecting ends 1121 of the heating element 112 can pass through the through hole 124, which is troublesome to operate. The setting of the guiding surface 1241 makes it only necessary to assemble the position of the guiding liquid 111 in place during assembly, and the two connecting ends 1121 can automatically pass through the through hole 124 under the guidance of the guiding surface 1241, thereby reducing the difficulty of assembling the heating component 110.

[0051] In a specific embodiment, see Figure 5 and Figure 8In order to reduce the lateral size of the atomizer seat 120, when the liquid guide 111 is transversely mounted on the atomizer seat 120, the two connecting ends 1121 of the heating element 112 are close to the two opposite inner side walls of the atomizer seat 120. Therefore, the through hole 124 only forms a guide surface 1241 at a position away from the inner side wall of the atomizer seat 120, and guides the connecting end 1121 through the guide surface 1241. It can be understood that in other embodiments of the present application, when the size of the atomizer seat 120 allows, the through hole 124 can be formed with a guide surface 1241 along the circumferential direction toward one end of the liquid guide 111.

[0052] In one embodiment, see Figure 8 , the guide surface 1241 is a partial conical surface, that is, the cross-sectional area of ​​the inner wall of the through hole 124 gradually decreases from the end facing the liquid guide 111 to the direction away from the liquid guide 111. It can be understood that in other embodiments of the present application, the guide surface 1241 can also be a curved surface or an arc surface, which is not limited here.

[0053] In one embodiment, see Figure 5 and Figure 6 At least two limiting grooves 125 are formed on the outer side of the bottom of the atomizer seat 120, one of which is communicated with the through hole 124. The connecting end 1121 includes at least two limiting sections 1122 and a connecting section 1123 connected between two adjacent limiting sections 1122. Each limiting section 1122 is limited in each limiting groove 125. The connecting section 1123 is attached to the outer side of the bottom of the atomizer seat 120 and is used to be electrically connected to the battery assembly 200.

[0054] During assembly, the connecting end 1121 can be passed through the through hole 124 into one of the limiting grooves 125, and then the connecting end 1121 can be bent in sequence to form a plurality of limiting sections 1122, and a connecting section 1123 is provided between each two adjacent limiting sections 1122, and each limiting section 1122 is inserted into the corresponding limiting groove 125 in sequence, so that the connecting section 1123 is presented at a position between two adjacent limiting grooves 125 of the atomizer seat 120. When the battery assembly 200 is connected to the atomizer seat 120, the connecting section 1123 can directly abut against the battery assembly 200 to form an electrical connection.

[0055] In one embodiment, see Figure 6The inner side wall of the limiting groove 125 is concave to form a receiving groove 126, and the limiting section 1122 is inserted into the receiving groove 126 from the limiting groove 125 and is received in the receiving groove 126. The cross-sectional dimension of the limiting groove 125 is much larger than the cross-sectional dimension of the limiting section 1122, so that the limiting section 1122 can be easily inserted into the limiting groove 125, and the setting of the receiving groove 126 can make the limiting section 1122 inserted into the limiting groove 125 be stuck in the receiving groove 126, and the limiting section 1122 is limited by the receiving groove 126 to prevent the limiting section 1122 from sliding in the limiting groove 125 and causing unstable connection.

[0056] For details, please refer to Figure 6 The limiting groove 125 is used to form an inner side wall of the receiving groove 126 , and at least the portion connected to the receiving groove 126 is arranged in a V-shape, so as to guide the limiting section 1122 into the receiving groove 126 .

[0057] In one embodiment, the limiting groove 125 is formed on the outer side of the bottom of the atomizer seat 120, and the limiting groove 125 does not penetrate the bottom of the atomizer seat 120. It can be understood that in other embodiments of the present application, the limiting groove 125 can also penetrate the bottom of the atomizer seat 120, and the limiting section 1122 can be set through the limiting groove 125 and extend to another limiting groove 125 on the inner side of the bottom of the atomizer seat 120.

[0058] In one embodiment, see Figure 5 and Figure 6 , the connecting end 1121 includes two limiting sections 1122 arranged at a relative interval, and a connecting section 1123 is connected between the two limiting sections 1122. The atomizer seat 120 is provided with limiting grooves 125 at positions corresponding to the two limiting sections 1122, one of which is connected to the through hole 124, and the two limiting sections 1122 are respectively inserted into the limiting grooves 125 and received in the receiving groove 126, and the connecting section 1123 between the two limiting sections 1122 is fitted and abutted against the outer side of the bottom of the atomizer seat 120. It can be understood that in other embodiments of the present application, the number of limiting sections 1122 can also be one, three or more than three, and the number of connecting sections 1123 can also be two, three or more than three, which is not limited here.

[0059] In one embodiment, the connection end 1121 is fixed to the atomizer seat 120 by applying glue. Specifically, glue is applied at the position of the connection end 1121 that does not abut against the battery assembly 200 to firmly fix the connection end 1121 on the atomizer seat 120 to prevent the connection end 1121 from being separated from the atomizer seat 120 during use, resulting in poor connection.

[0060] In one embodiment, see Figure 5, glue can be applied on each limiting segment 1122 of the connection end 1121 to firmly fix the limiting segment 1122 in the receiving groove 126. It can be understood that in other embodiments of the present application, the connection end 1121 can also directly extend to the outside of the bottom of the atomizer seat 120, and then glue is applied on multiple points of the connection end 1121 to fix the connection end 1121 on the atomizer seat 120, and the position on the connection end 1121 without glue can directly form an electrical connection with the battery assembly 200.

[0061] In one embodiment, see Figure 3 and Figure 4 The battery assembly 200 includes a battery shell 210, a circuit board 220, and an electrical connector 230. The electrical connector 230 is electrically connected to the circuit board 220. The electrical connector 230 at least partially extends out of the battery shell 210 to be electrically connected to the connection terminal 1121. In this embodiment, the electrical connector 230 on the circuit board 220 is directly extended out of the battery shell 210, and the connection terminal 1121 in the heating element 112 is directly extended out of the atomizer seat 120, and an electrical connection is formed between the electrical connector 230 and the connection terminal 1121, thereby reducing the metal conductor between the circuit board 220 and the heating element 112, reducing the conduction resistance between the circuit board 220 and the heating element 112, reducing the conduction risk, reducing the conduction parts, and reducing the structural cost and assembly cost.

[0062] In one embodiment, see Figure 4 and Fig.10 The electrical connector 230 is a spring connector 230 a , which is directly attached to the circuit board 220 in a patch manner. The spring connector at least partially extends out of the battery shell 210 to elastically abut against the connection end 1121 .

[0063] For details, please refer to Figure 4 and Fig.10 The spring connector 230a includes a patch portion 231a and a plug portion 232a. The patch portion 231a is used to be patched on the circuit board 220. The circuit board 220 is provided with a plug hole 221. The plug portion 232a is inserted into the plug hole 221, so as to realize the positioning of the spring connector 230a on the circuit board 220 and also ensure the installation reliability of the spring connector 230a on the circuit board 220. In addition, the spring connector 230a also includes an elastic portion 233a, which is used to elastically abut against the connection end 1121 to form an electrical connection between the circuit board 220 and the atomizer 100.

[0064] In one embodiment, see Figure 3The battery assembly 200 also includes a battery 240, which is electrically connected to the circuit board 220. The battery shell 210 is formed with a mounting cavity 211, and the circuit board 220 and the battery 240 are both mounted in the mounting cavity 211. The top of the battery shell 210 is formed with a mounting opening 212 that is connected to the mounting cavity 211. A sealing structure 250 is installed at the mounting opening 212. A through-opening 253 is formed in the sealing structure 250. The elastic portion 233a of the spring connector passes through the through-opening 253, and the elastic portion 233a is interference-fitted with the through-opening 253. Such a configuration can ensure that the top of the mounting cavity 211 is sealed, and prevent the condensate in the atomizer 100 from entering the mounting cavity 211 through the top of the battery shell 210 and corroding the circuit board 220 and the battery 240.

[0065] In one embodiment, see Figure 4 The sealing structure 250 and the battery shell 210 form an interference fit, the sealing structure 250 elastically abuts against the circuit board 220, and the two spring connectors 230a are respectively received on the sealing structure 250 and extend from the through opening 253 of the sealing structure 250.

[0066] In one embodiment, see Figure 4 , an airflow sensor 260 is mounted on the circuit board 220, the airflow sensor 260 is electrically connected to the circuit board 220, and the outer cover of the airflow sensor 260 is arranged on the first sealing member 251.

The inner tube 131 is formed with an air guide channel 134. The outer tube 132 is sleeved outside the inner tube 131. The top of the outer tube 132 is integrally connected with the top of the inner tube 131 to form a suction nozzle 133. The outer tube 132 and the inner tube 131 are enclosed together to form a liquid storage chamber 135. The upper atomization seat 122 and the lower atomization seat 121 are both arranged on the inner side of the bottom of the outer tube 132. The upper atomization seat 122 is formed with an air outlet connected to the atomization chamber 123. The air outlet is connected to the air guide channel 134. The opposite ends of the liquid guide 111 extend into the liquid storage chamber 135 to absorb and conduct the atomized medium. The lower atomization seat 121 is snap-fitted with the outer tube 132, and the lower atomization seat 121 is snap-fitted with the battery shell 210.

When the battery shell 210 is connected to the atomizer seat 120, the connection end 1121 of the heating element 112 just abuts against the exposed copper 230b, thereby forming an electrical connection between the atomizer 100 and the battery assembly 200.

[0074] Optionally, see Fig.11 , the circuit board 220 can be extended longitudinally, and two exposed coppers 230b are formed on one side of the circuit board 220. In order to make the connection end 1121 fit on the exposed copper 230b, the connection end 1121 can be extended longitudinally out of the atomizer seat 120. Alternatively, the circuit board 220 can be partially extended longitudinally, and the part of the circuit board 220 extending out of the battery shell 210 can be extended horizontally. Two exposed coppers 230b are formed on the circuit board 220 and arranged toward the atomizer seat 120. When the battery shell 210 is connected to the atomizer seat 120, the connection sections 1123 of the two connection ends 1121 just abut against the two exposed coppers 230b, thereby forming an electrical connection.
