Description

Technical Field

[0001] This application relates to the technical field of atomizers, and more specifically, to a heating element, an atomizer, and an electronic atomization device. Background Art

[0002] When the mesh heating wire of the atomizer is assembled in combination with the liquid guide cotton wrapping, the width of the liquid guide cotton wrapping must be higher than the upper and lower sides of the mesh heating wire by a certain distance to ensure that the heating area of the mesh heating wire can be completely within the wrapping area of the liquid guide cotton wrapping, so as to prevent the mesh heating wire from dry burning and affecting its lifespan. Then, during the use of the atomizer, as the liquid aerosol matrix stored in the liquid guide cotton wrapping is consumed, the top of the liquid guide cotton wrapping will collapse towards the center of the cavity surrounded by the mesh heating wire under the influence of gravity, thereby affecting the ventilation of the gas channel of the atomizer.

[0012] By adopting the above solution, in at least one of the first support frame and the second support frame, a plurality of first grooves are provided at intervals, so that the first grooves are used to ensure the structural stability of the support frame and reduce the risk of irregular deformation of the support frame; the first support frame and the second support frame are respectively arranged in the height direction of the heating element, so that the first support frame and the second support frame can ensure the stability of the overall shape of the heating element and reduce the risk of irregular deformation of the heating element, thereby facilitating the smooth flow of air when the atomizer is in use.

[0013] In some implementation manners, the first groove is a through hole; or, the first groove is a blind hole.

[0014] By adopting the above solution, it is convenient for manufacturing.

[0015] In some implementation manners, the first support frame is curved, and a plurality of first grooves are provided on the first support frame;

[0016] The second support frame is curved, and a plurality of first grooves are provided on the second support frame.

[0017] By adopting the above solution, when manufacturing the heating element, it is beneficial for the first support frame and the second support frame to be bent into shape, such as being bent into an arc shape, reducing the risk of irregular deformation.

[0018] In some implementation manners, the heating element further includes an extension part, and the length of the extension part extends in the direction of the heating mesh;

[0019] At least one of the first support frame and the second support frame is fixedly connected with the extension part;

[0020] In the height direction of the heating element, the extension part is spaced apart from the heating mesh.

[0021] By adopting the above solution, the extension part can ensure the stability of the overall shape of the heating element and reduce the risk of irregular deformation of the heating element.

[0022] In some implementation manners, one side of the heating mesh facing the first channel has a protrusion.

[0029] In some implementation manners, the conductive part is in a plate-like structure; the heating element further includes a conductive pin, and the conductive pin is fixed on the conductive part.

[0030] By adopting the above solution, the conductive pin is used to electrically connect with a power supply device to realize the heating of the heating mesh.

[0031] The second aspect of the present application provides an atomizer, which includes a first liquid guide cotton and the heating element in any of the above implementation manners, and the first liquid guide cotton wraps the heating element.

[0032] In some implementation manners, in the height direction of the heating element, the first liquid guide cotton has opposite first end face and second end face;

[0033] In the height direction of the heating element, the first support frame and the second support frame are located between the first end face and the second end face.

[0034] By adopting the above solution, in the present application, a plurality of first grooves are formed at least on one of the first support frame and the second support frame and are distributed at intervals. In this way, the first grooves are used to ensure the structural stability of the support frame and reduce the risk of irregular deformation of the support frame; the first support frame and the second support frame are respectively arranged in the height direction of the heating element. In this way, the first support frame and the second support frame can ensure the shape stability of the overall heating element and reduce the risk of irregular deformation of the heating element, which is beneficial to ensuring the smooth air flow during the use of the atomizer.

[0035] In some implementation manners, the atomizer further includes an atomization support frame and a second liquid guide cotton. The atomization support frame has a first accommodation cavity, and the first liquid guide cotton is inserted into the first accommodation cavity; the second liquid guide cotton wraps the atomization support frame.

[0036] By adopting the above solution, the cooperation between the second liquid guide cotton and the first liquid guide cotton is beneficial to controlling the flow rate of the liquid aerosol matrix to the heating element.

[0037] In some implementations, the atomizer further includes an atomization cover, the atomization cover having a second accommodation cavity, and the heating mesh, the first liquid guide cotton, the atomization bracket, and the second liquid guide cotton being located in the second accommodation cavity;

[0038] The atomization cover has a liquid inlet through hole communicating with the second accommodation cavity.

[0039] By adopting the above solution, the atomization cover can be used to direct the airflow.

[0040] In some implementations, the atomizer further includes a top cover and a housing, the housing having an air outlet cavity and a liquid storage cavity for storing an aerosol matrix, the top cover having an air inlet cavity, the air inlet cavity communicating with the second accommodation cavity, the second accommodation cavity communicating with the air outlet cavity, and the liquid inlet through hole communicating with the liquid storage cavity;

[0041] The top cover is sealingly connected to the housing, one end of the atomization cover is sealingly connected to the air outlet cavity, and the other end of the atomization cover is inserted and mated with the top cover.

[0042] By adopting the above solution, the liquid storage cavity can be relatively closed, so that the aerosol matrix in the liquid storage cavity can only flow out from the liquid inlet through hole, be guided by the second liquid guide cotton, and then, under capillary action, flow through the first liquid guide hole to the second liquid guide cotton, and then flow to the surface of the heating mesh of the heating element under capillary action; when the user sucks, the gas flows into the first channel through the air inlet cavity, then flows into the air outlet cavity through the second accommodation cavity, and finally flows out from the outlet of the air outlet cavity.

[0043] In some implementations, the atomizer further includes a first seal and a first sealing ring; the top cover and the housing are sealingly connected through the first seal; one end of the atomization cover and the air outlet cavity are sealingly connected through the first sealing ring.

[0044] By adopting the above solution, a sealing effect can be achieved to prevent the aerosol matrix from leaking from the connection.

[0045] In some implementations, the atomizer further includes a bottom cover, the bottom cover having an air inlet hole, and the air inlet hole communicating with the air inlet cavity;

[0046] The bottom cover is sealingly connected to the top cover.

[0047] By adopting the above solution, during use, the airflow enters the air inlet cavity through the air inlet hole.

[0048] In some implementations, the atomizer further includes a second seal, and the bottom cover and the top cover are sealingly connected through the second seal.

[0049] By adopting the above solution, liquid leakage can be reduced and the sealing performance during use can be ensured.

[0050] In some implementation manners, the atomizer further includes a liquid absorption member. The top cover and the bottom cover cooperate to form a buffer cavity, and the liquid absorption member is located in the buffer cavity;

[0051] The air inlet hole is communicated with the air inlet cavity through the buffer cavity.

[0053] In some implementation manners, the atomizer further includes a liquid injection plug. The housing has a liquid injection hole communicated with the liquid storage cavity, and the liquid injection plug is inserted into the liquid injection hole.

[0054] By adopting the above solution, a liquid aerosol matrix can be added to the liquid storage cavity.

[0055] In some implementation manners, the atomizer further includes a conductive electrode, and the conductive electrode is electrically connected to the heating element.

[0056] By adopting the above solution, the conductive electrode can be abutted against the conductive spring pin of the power supply device, so as to energize the heating element and realize the heating of the heating mesh.

[0057] In some implementation manners, the atomizer further includes a housing and a flow guiding structure. The housing has an air outlet cavity, and the first channel is communicated with the air outlet cavity;

[0058] The flow guiding structure is used to enable the gas to flow in the direction of the air outlet cavity along the surface of the heating mesh facing the first channel.

[0059] By adopting the above solution, more air flow passing through the surface of the heating wire can take away part of the heat, which can reduce the risk of overheating of the heating mesh, extend the service life of the heating mesh and the first liquid guiding cotton, and reduce the decomposition of the aerosol matrix; in addition, the air flow can take away the atomized aerosol matrix faster and reduce the retention of the atomized aerosol matrix near the heating mesh.

[0060] In some implementation manners, the first support frame is close to the air outlet of the air outlet cavity, and the second support frame is far from the air outlet of the air outlet cavity;

[0061] The flow guiding structure is a conical structure, and the tip of the conical structure faces away from the air outlet of the air outlet cavity.

[0062] By adopting the above solution, it is beneficial to realize the air flow direction towards the surface of the heating mesh facing the first channel, that is, to flow along the inner surface of the heating mesh.

[0063] In a third aspect of the present application, an electronic atomization device is provided, which includes: a power supply device and the atomizer described in any of the above implementation manners, and the atomizer is detachably connected to the power supply device.

[0064] By adopting the above solution, in the present application, a plurality of first grooves are provided at least on one of the first support frame and the second support frame, and are spaced apart from each other. In this way, the first grooves are used to ensure the structural stability of the support frame and reduce the risk of irregular deformation of the support frame; the first support frame and the second support frame are respectively arranged in the height direction of the heating element. In this way, the first support frame and the second support frame can ensure the stability of the overall shape of the heating element and reduce the risk of irregular deformation of the heating element, thereby being beneficial to ensuring smooth air flow when the atomizer is in use.

Detailed implementation manners

[0089] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0090] In one or more embodiments, the present application provides an electronic atomization device, which includes: a power supply device and an atomizer 200, and the atomizer 200 is detachably connected to the power supply device.

[0091] In some embodiments, the power supply device includes a housing, a battery, a circuit board and a spring conductive needle. The battery is electrically connected to the circuit board, and the spring conductive needle is electrically connected to the atomizer 200. The housing has a housing cavity, and the housing cavity includes an inner cavity and an insertion cavity. The battery and the circuit board are installed in the inner cavity, and the spring conductive needle is located in the insertion cavity; the atomizer 200 is inserted into the insertion cavity to realize the electrical connection between the spring conductive needle and the atomizer 200, so as to supply power to the atomizer 200.

[0092] In one embodiment, the atomizer includes a mesh heating wire and a liquid guide cotton wrap. When the mesh heating wire of the atomizer is assembled in contact with the liquid guide cotton wrap, the width of the liquid guide cotton wrap must be higher than the upper and lower sides of the mesh heating wire by a certain distance to ensure that the heating area of the mesh heating wire is completely within the wrapping area of the liquid guide cotton wrap, so as to prevent the mesh heating wire from dry burning and affecting its lifespan. Then, during the use of the atomizer, as the liquid aerosol matrix stored in the liquid guide cotton wrap is consumed, the top of the liquid guide cotton wrap will collapse towards the center of the cavity surrounded by the mesh heating wire under the influence of gravity, thereby affecting the ventilation of the gas passage of the atomizer.

[0093] To this end, the embodiments of the present application provide a heating element 100 and an atomizer 200 to solve the problem that the top of the liquid guide cotton wrap in the related art will collapse towards the center of the cavity surrounded by the mesh heating wire under the influence of gravity, thereby affecting the ventilation of the gas passage of the atomizer 200. The heating element 100 and the atomizer 200 in the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0094] Figure 1 It is a schematic structural diagram when the heating element 100 provided by the embodiment of the present application is cooperated with the first liquid guide cotton 201; Figure 2 is Figure 1 a schematic structural diagram from another perspective; Figure 3 is along Figure 2 the cross-sectional view taken along the line A-A in Figures 1 to 3 As shown in

[0095] Figure 4 It is a schematic structural diagram of the heating element 100 provided by the embodiment of the present application; Figure 5 It is a schematic structural diagram of the heating element 100 from another perspective provided by the embodiment of the present application; Figure 6 It is a schematic structural diagram of the heating element 100 when the conductive pins 109 are not installed in the embodiment of the present application;

[0096] Figure 7 is Figure 6 the front view; as shown in combination with Figures 4 to 7As shown, in the embodiment of the present application, the heating element 100 includes: a heating mesh 101, a conductive part 102, a first support frame 103, and a second support frame 104; the heating mesh 101 is curved, the heating mesh 101 forms a first channel 105, and the heating mesh 101 has opposite first and second side edges; the first and second side edges are respectively connected to the conductive part 102; the first support frame 103 is fixedly connected to the conductive part 102 located on the first side edge; the second support frame 104 is fixedly connected to the conductive part 102 located on the second side edge; wherein, at least one of the first support frame 103 and the second support frame 104 is provided with a plurality of first grooves 107 distributed at intervals. In the height direction of the heating element 100, the first support frame 103, the heating mesh 101, and the second support frame 104 are arranged in sequence, the first support frame 103 is spaced from the heating mesh 101, and the second support frame 104 is spaced from the heating mesh 101.

[0097] In the present application, at least one of the first support frame 103 and the second support frame 104 is provided with a plurality of first grooves 107 distributed at intervals. In this way, the first grooves 107 are utilized to ensure the structural stability of the support frame and reduce the risk of irregular deformation of the support frame; the first support frame 103 and the second support frame 104 are respectively arranged in the height direction of the heating element 100. In this way, the first support frame 103 and the second support frame 104 can be used to ensure the stability of the overall shape of the heating element 100 and reduce the risk of irregular deformation of the heating element 100, which is beneficial to reducing the possibility of the first liquid guide cotton 201 collapsing towards the center of the first channel 105, thereby ensuring the smooth flow of the air flow in the first channel 105, and then being beneficial to ensuring the smooth flow of the air flow when the atomizer 200 is in use.

[0098] Combined Figures 4 to 7 As shown, in some embodiments, the height direction of the heating element 100 is parallel to the height direction of the atomizer 200; the first support frame 103 is located above the second support frame 104. After the heating mesh 101 is bent, it forms a C-shaped structure, so that the heating mesh 101 forms the first channel 105, and the first channel 105 is a channel for air flow. The first and second side edges are parallel, and the first and second side edges are respectively parallel to the height direction of the heating element 100. The number of the conductive parts 102 is two, one conductive part 102 is fixed to the first side edge, and the other conductive part 102 is fixed to the second side edge. The number of the first support frames 103 can be one, and the number of the second support frames 104 can be one. The heating mesh 101, the conductive part 102, the first support frame 103, and the second support frame 104 form an integral structure. For example, a metal sheet can be processed by stamping or laser cutting processes to form a planar structure, and finally the planar structure is curled to form the integral structure.

[0099] It should be noted that in some other possible embodiments, the number of the first support frames 103 can also be multiple, for example, 2 or 3. The multiple first support frames 103 are spaced apart along the height direction of the heating element 100 or the multiple first support frames 103 are arranged along the height direction of the heating element 100 and are in contact with each other. The number of the second support frames 104 can also be multiple, for example, 2 or 3. The multiple second support frames 104 are spaced apart along the height direction of the heating element 100 or the multiple second support frames 104 are arranged along the height direction of the heating element 100 and are in contact with each other.

[0100] Combined with Figure 6 and Figure 7 As shown, in some embodiments, the first support frame 103 is curved, and a plurality of first grooves 107 are provided on the first support frame 103; the second support frame 104 is curved, and a plurality of first grooves 107 are provided on the second support frame 104. The first grooves 107 are respectively formed on the first support frame 103 and the second support frame 104. In this way, when manufacturing the heating element 100, it is beneficial for the first support frame 103 and the second support frame 104 to be bent into shape, for example, bent into an arc shape, reducing the risk of irregular deformation. Exemplarily, the plurality of first grooves 107 on the first support frame 103 are equally spaced along the circumferential direction (i.e., the length extension direction) of the first support frame 103; the plurality of first grooves 107 on the second support frame 104 are equally spaced along the circumferential direction (i.e., the length extension direction) of the second support frame 104; both the first support frame 103 and the second support frame 104 are plate-like structures.

[0101] Combined with Figure 6 and Figure 7 As shown, in some embodiments, the first groove 107 is a through hole, which is convenient for manufacturing. Exemplarily, when manufacturing the heating element 100, through holes are processed at the positions corresponding to the first support frame 103 and the second support frame 104 on a planar structure. The through holes can be rectangular through holes or circular through holes; the width of the first support frame 103 in the height direction of the heating element 100 is equal to the width of the second support frame 104 in the height direction of the heating element 100. The ratio of the width d1 of the first support frame 103 in the height direction of the heating element 100 to the aperture d2 of the through hole in the height direction of the heating element 100 is 2 to 3. For example, the ratio can be 2, 2.4, 2.5 or 3.

[0102] It should be noted that in some other possible embodiments, the width of the first support frame 103 in the height direction of the heating element 100 may also be unequal to the width of the second support frame 104 in the height direction of the heating element 100. In addition, the first groove 107 may also be a blind hole. For ease of manufacturing, a stamping process may be used to form a blind hole on a planar structure. Due to the stamping process, a blind hole form (i.e., a concave form) appears on one side of the first support frame 103, while a convex form appears on the opposite side of the first support frame 103. Similarly, a blind hole form (i.e., a concave form) appears on one side of the second support frame 104, while a convex form appears on the opposite side of the second support frame 104.

[0103] Combined Figure 6 with Figure 7 As shown, in some embodiments, the heating element 100 further includes an extension portion 108, and the length of the extension portion 108 extends in the direction of the heating grid 101; at least one of the first support frame 103 and the second support frame 104 is fixedly connected to the extension portion 108; in the height direction of the heating element 100, the extension portion 108 is spaced apart from the heating grid 101. By using the extension portion 108, the stability of the overall shape of the heating element 100 can be ensured, and the risk of irregular deformation of the heating element 100 can be reduced. Exemplarily, both the first support frame 103 and the second support frame 104 are fixedly connected to the extension portion 108; one end in the length direction of the first support frame 103 is fixedly connected to the conductive portion 102, and the other end in the length direction of the first support frame 103 is fixedly connected to the extension portion 108. One end in the length direction of the second support frame 104 is fixedly connected to the conductive portion 102, and the other end in the length direction of the second support frame 104 is fixedly connected to the extension portion 108. Thus, since the first side and the second side of the heating grid 101 are respectively connected to the conductive portion 102, the heating grid 101 is the heat generation area, while the first support frame 103, the second support frame 104, and the extension portion 108 mainly play a supporting role and can also play a certain heat dissipation effect.

[0104] In the height direction of the heating element 100, the ratio of the length d3 of the extension portion 108 to the width d1 of the first support frame 103 is 1.2 to 1.4. For example, the ratio can be 1.2, 1.3, 1.35, or 1.4.

[0105] See Figure 7As shown, in some embodiments, in the height direction of the heating element 100, the distance between the first support frame 103 and the heating mesh 101 is the first distance d4, and the distance between the second support frame 104 and the heating mesh 101 is the second distance d5; in the height direction of the heating element 100, the ratio of the height d8 of the heating mesh 101 to the first distance d4 is 2.5 to 3.5, and the ratio of the height d8 of the heating mesh 101 to the second distance d5 is 2.5 to 3.5. This can improve the structural stability of the overall heating element 100, and the first support frame 103 and the second support frame 104 are beneficial to ensure the smoothness of the first channel 105 and reduce the deformation of the heating mesh 101 during use. Exemplarily, in the height direction of the heating element 100, the ratio of the height d8 of the heating mesh 101 to the first distance d4 is 2.5, 3.0 or 3.5, and the ratio of the height d8 of the heating mesh 101 to the second distance d5 is 2.5, 3.0 or 3.5. Compared with the mesh heating wire, the height of the heating mesh 101 in this application is shortened. When the heating mesh 101 works, the heat is more concentrated, thereby increasing the amount of smoke and improving the user satisfaction.

[0106] In some embodiments, the conductive part 102 is a plate-like structure, which is convenient to manufacture so as to form an integral structure with the heating mesh 101, the first support frame 103, the second support frame 104 and the extension part 108. The heating element 100 further includes conductive pins 109, and the conductive pins 109 are fixed on the conductive part 102, so as to be electrically connected to a power supply device through the conductive pins 109 to realize the heating of the heating mesh 101. Exemplarily, the number of the conductive pins 109 is 2. One of the conductive pins 109 is fixedly connected to one conductive part 102, and the other conductive pin 109 is fixedly connected to the other conductive part 102. The conductive pin 109 and the conductive part 102 can be fixedly connected by welding or by a stamping process. The stamping process can be an embedding process or a spot pressing process. The embedding process is to form protrusions 110, grooves or other geometric features on a piece of metal and embed them into the holes, grooves or corresponding structures of another piece of metal to form a mechanical lock. The spot pressing process is a connection process that forms tiny fitting points (usually pits or deformation areas) on two stacked pieces of metal by stamping.

[0107] Figure 17 is a schematic structural diagram of the heating element and the first liquid guide cotton in the embodiment of the present application; see Figure 17As shown, in some other embodiments, one side of the heating mesh 101 facing the first channel 105 has protrusions 110. The use of the protrusions 110 helps to increase the effective contact area of the inner surface of the heating mesh 101, thereby enhancing the contact area between the heating mesh 101 and the liquid aerosol matrix and improving the atomization efficiency. Additionally, the protrusions 110 contribute to heat dispersion, reducing the occurrence of local overheating, lowering the risk of harmful substances being produced during the decomposition of the aerosol matrix during atomization, and simultaneously improving the taste consistency. Exemplarily, the protrusions 110 can be formed by a stamping process and can be in the shape of a spherical segment. The number of protrusions 110 is multiple, and the multiple protrusions 110 are spaced apart on the heating mesh 101. It should be noted that in some other possible embodiments, the protrusions 110 can also be in the shape of a cuboid.

[0108] In some embodiments, the atomizer 200 further includes a housing 203. The housing 203 has an air outlet cavity 204 and a liquid storage cavity 205 for storing the aerosol matrix, which facilitates the suction of the atomized aerosol matrix. The atomized aerosol matrix can be referred to as an aerosol. The liquid aerosol matrix is stored in the liquid storage cavity 205; the first channel 105 of the heating element 100 is in communication with the air outlet cavity 204.

[0109] Combined Figure 2 and 3 As shown, in some, in the height direction of the heating element 100, the first liquid guide cotton 201 has opposite first end face 207 and second end face 208; in the height direction of the heating element 100, the first support frame 103 and the second support frame 104 are located between the first end face 207 and the second end face 208; in this way, it can ensure the support of the first support frame 103 and the second support frame 104 for the first liquid guide cotton 201. Exemplarily, the first end face 207 is above the second end face 208, the first end face 207 is close to the air outlet 206 of the air outlet cavity 204, and the second end face 208 is far from the air outlet 206 of the air outlet cavity 204. The first support frame 103 is close to the air outlet 206 of the air outlet cavity 204, and the second support frame 104 is far from the air outlet 206 of the air outlet cavity 204. The distance d6 between the first end face 207 and the upper edge 209 of the first support frame 103 can be 0.1 - 0.2 mm, for example, it can be 0.1 mm, 0.15 mm or 0.2 mm. The distance d7 between the second end face 208 and the lower edge 210 of the second support frame 104 can be 0.1 - 0.2 mm, for example, it can be 0.1 mm, 0.15 mm or 0.2 mm; in this way, the first support frame 103 and the second support frame 104 of the heating element 100 can effectively support the first liquid guide cotton 201 and prevent the first liquid guide cotton 201 from sagging towards the center of the first channel 105 during the suction process.

[0110] It should be noted that in some other possible embodiments, the first end face 207 may also be flush with the upper edge 209 of the first support frame 103, and the second end face 208 is flush with the lower edge 210 of the first support frame 103.

[0111] Figure 11 is a sectional view along Figure 10 section line B-B in; Figure 12 is an exploded view of the atomizer 200 provided by the embodiment of the present application; Figure 14 is a schematic structural diagram when the top cover 220, the atomization support 211, the first liquid guide cotton 201 and the heating element 100 are matched in the embodiment of the present application;

[0112] Figure 15 is a schematic structural diagram when the atomization cover 217, the top cover 220, the atomization support 211, the first liquid guide cotton 201 and the heating element 100 are matched in the embodiment of the present application; Combining Figure 11 , Figure 12 , Figure 14 and Figure 15 shown, in some embodiments, the atomizer 200 further includes an atomization support 211 and a second liquid guide cotton 212. The atomization support 211 has a first accommodation cavity 213, and the first liquid guide cotton 201 is inserted into the first accommodation cavity 213; the second liquid guide cotton 212 wraps the atomization support 211. In this way, the cooperation between the second liquid guide cotton 212 and the first liquid guide cotton 201 is beneficial to controlling the flow rate of the liquid aerosol matrix to the heating element 100. Exemplarily, the second liquid guide cotton 212 is tubular, and the second liquid guide cotton 212 is sleeved on the atomization support 211, so as to realize the wrapping of part of the structure of the atomization support 211. The first liquid guide cotton 201 wraps the heating element 100, so the second liquid guide cotton 212 also realizes the wrapping of the first liquid guide cotton 201 and the heating element 100. The atomization support 211 also has a first liquid guide hole 214. The number of the first liquid guide holes 214 is multiple, and the multiple first liquid guide holes 214 are distributed around the circumference of the atomization support 211; the first liquid guide hole 214 is communicated with the first accommodation cavity 213; the atomization support 211 also has a limit notch 215; the first liquid guide cotton 201 has a limit part 216, and the limit part 216 extends into the limit notch 215, so as to facilitate the assembly of the first liquid guide cotton 201 and prevent the first liquid guide cotton 201 from rotating around the axis of the first through hole 202. Since the limit part 216 is engaged in the limit notch 215, the first liquid guide cotton 201 can also be prevented from moving up and down in the height direction of the atomizer 200.

[0113] Combining Figure 11 , Figure 12 and Figure 15As shown, in some embodiments, the atomizer 200 further includes an atomization cover 217. The atomization cover 217 has a second accommodation cavity 218. The heating mesh 101, the first liquid guide cotton 201, the atomization bracket 211, and the second liquid guide cotton 212 are located in the second accommodation cavity 218. The atomization cover 217 has a liquid inlet through hole 219 communicating with the second accommodation cavity 218. The atomization cover 217 can be used to direct the airflow. Exemplarily, the heating mesh 101, the first support frame 103, the second support frame 104, and the conductive part 102 are also located in the second accommodation cavity 218. The number of the liquid inlet through holes 219 is multiple, and the multiple liquid inlet through holes 219 are circumferentially spaced apart around the atomization cover 217.

[0114] Combined with Figure 11 and Figure 12 As shown, in some embodiments, the atomizer 200 further includes a top cover 220. The top cover 220 has an air inlet cavity 221. The air inlet cavity 221 communicates with the second accommodation cavity 218. The second accommodation cavity 218 communicates with the air outlet cavity 204. The liquid inlet through hole 219 communicates with the liquid storage cavity 205. The connection between the top cover 220 and the outer shell 203 is hermetically connected. One end of the atomization cover 217 is hermetically connected to the air outlet cavity 204, that is, one end of the atomization cover 217 is hermetically connected to the air inlet 248 of the air outlet cavity 204. In this way, after the gas flows out of the second accommodation cavity 218, it enters the air outlet cavity 204 and flows out from the air outlet 206. The other end of the atomization cover 217 is inserted and matched with the top cover 220. In this way, the liquid storage cavity 205 can be relatively closed, so that the aerosol matrix in the liquid storage cavity 205 can only flow out from the liquid inlet through hole 219, and is guided by the second liquid guide cotton 212. Then, under the capillary action, it flows through the first liquid guide hole 214 to the second liquid guide cotton 212, and then flows to the surface of the heating mesh 101 of the heating element 100 under the capillary action. When the user sucks, the gas flows into the first channel 105 through the air inlet cavity 221, then flows into the air outlet cavity 204 through the second accommodation cavity 218, and finally flows out from the outlet of the air outlet cavity 204.

[0115] Figure 13 It is a schematic structural diagram when the heating element and the top cover are matched in the embodiment of the present application; combined with Figure 12 and Figure 13 As shown, in some embodiments, the top cover 220 includes a main body portion 222 and a tubular structure 223 fixedly connected to the main body portion 222. One side of the main body portion 222 facing the air outlet cavity 204 has a second groove 224. The tubular structure 223 is fixed in the second groove 224 so that the second groove 224 forms an annular groove. The air inlet cavity 221 is the lumen of the tubular structure 223. The other end of the atomization cover 217 is inserted into the second groove 224, and the tubular structure 223 extends into the second accommodation cavity 218 of the atomization cover 217. One end of the atomization bracket 211 is inserted into the second groove 224.

[0116] Figure 18 It is a schematic structural diagram when the heating element, the first liquid guide cotton and the diversion structure cooperate in the embodiment of the present application; combined with Figure 13 and Figure 18 As shown, in some other embodiments, the atomizer 200 further includes a diversion structure 225. The diversion structure 225 is used to enable the gas to flow in the direction of the air outlet cavity 204 along one side of the heating mesh 101 facing the first channel 105. In this way, more airflows can flow through the surface of the heating wire to take away part of the heat, which can reduce the risk of overheating of the heating mesh 101, extend the service life of the heating mesh 101 and the first liquid guide cotton 201, and reduce the decomposition of the aerosol matrix; in addition, the airflow can take away the atomized aerosol matrix faster and reduce the retention of the atomized aerosol matrix near the heating mesh 101.

[0117] Combined with Figure 13 and Figure 18 As shown, in some other embodiments, the diversion structure 225 is a conical structure. The conical structure is close to the intake end 249 of the first channel 105. After the gas flows out of the intake cavity 221, it enters the intake end 249 of the first channel 105 and flows out from the outlet end 250 of the first channel 105 and enters the second accommodation cavity 218; the first support frame 103 is located on the side where the intake end 249 of the first channel 105 is located, and the second support frame 104 is located on the side where the outlet end 250 of the first channel 105 is located; the tip of the conical structure faces away from the air outlet 206 of the air outlet cavity 204, which is beneficial to realizing the airflow flowing towards the side of the heating mesh 101 facing the first channel 105, that is, flowing along the inner surface of the heating mesh 101. Exemplarily, the conical structure is fixedly connected to the top cover 220. An integral structure can be formed between the conical structure and the top cover 220 by using an integral molding process to realize the fixation of the two. The conical structure can be connected to the tubular structure 223 of the top cover 220 through a connecting rod 226. The number of connecting rods 226 can be 2 or 3, and multiple connecting rods 226 are distributed along the circumferential direction of the conical structure. The diameter of the bottom surface of the conical structure is smaller than the diameter of the first channel 105, so that an intake gap can be formed between the conical structure and the first channel 105, so that the airflow flows along the inner surface of the heating mesh 101. Since the heating mesh 101 is located in the first through hole 202 of the first liquid guide cotton 201, at least part of the structure of the conical structure can extend into the first through hole 202 of the first liquid guide cotton 201.

[0118] Combined with Figure 11 and Figure 12As shown, in some embodiments, the atomizer 200 further includes a first seal 227 and a first sealing ring 228; the top cover 220 and the outer shell 203 are sealingly connected through the first seal 227; one end of the atomizing cover 217 and the air outlet cavity 204 are sealingly connected through the first sealing ring 228, so as to achieve a sealing effect and prevent the aerosol matrix from leaking from the connection. Exemplarily, the atomizing cover 217 has an annular groove, and the first sealing ring 228 is installed in the annular groove. After one end of the atomizing cover 217 is inserted into the air outlet cavity 204, an interference fit can be achieved between the first sealing ring 228 and the cavity wall of the air outlet cavity 204, thereby ensuring the sealing of the connection. The first sealing ring 228 can be an O-ring. The shape of the first seal 227 can also be specifically designed according to the fit between the top cover 220 and the outer shell 203, as long as the sealing between the two can be ensured; the material of the first seal 227 can be silica gel, rubber or polytetrafluoroethylene; the rubber can be fluororubber.

In this way, during use, the air flow enters the air inlet cavity 221 through the air inlet hole 230. Exemplarily, the number of the air inlet holes 230 can be one or more. When the number of the air inlet holes 230 is multiple, the number can be two, three or four. The top cover 220 has a card hole 231, and the bottom cover 229 has a first card table 232.

The bottom cover 229 and the top cover 220 are sealingly connected through the second seal 233. The material of the second seal 233 can be silica gel, rubber or polytetrafluoroethylene; the rubber can be fluororubber. Exemplarily, the second seal 233 has a liquid guide cavity 234 in a frustum shape, and the liquid guide cavity 234 is communicated with the air inlet cavity 221 of the top cover 220. In this way, the condensate during use flows downward from the air inlet cavity 221 and then flows downward along the cavity wall of the liquid guide cavity 234.

[0121] In combination with Figure 11 and Figure 12As shown, in some embodiments, the atomizer 200 further includes a liquid absorbent member 235. The top cover 220 and the bottom cover 229 cooperate to form a buffer cavity 236, and the liquid absorbent member 235 is located in the buffer cavity 236; the air inlet hole 230 is connected to the air inlet cavity 221 through the buffer cavity 236. In this way, the liquid absorbent member 235 can absorb the condensate flowing down along the inner wall of the liquid guide cavity 234. Exemplarily, the second seal 233 is located in the buffer cavity 236, and the material of the liquid absorbent member 235 can be cotton, polyurethane sponge or polypropylene fiber.

[0123] Combined with Figure 11 and Figure 16 As shown, in some embodiments, the atomizer 200 further includes a second sealing ring 247. The bottom cover 229 and the outer shell 203 are inserted and connected, and the second sealing ring 247 is sleeved on the bottom cover 229. When the bottom cover 229 and the outer shell 203 are inserted, an interference fit between the second sealing ring 247 and the inner wall of the outer shell 203 can be achieved, thereby ensuring the sealing of the connection. The second sealing ring 247 can be an O-ring.

[0124] Combined with Figure 8 and Figure 11 As shown, in some embodiments, the atomizer 200 further includes a liquid injection plug 238. The outer shell 203 has a liquid injection hole 246 communicating with the liquid storage cavity 205, and the liquid injection plug 238 is inserted into the liquid injection hole 246, so that a liquid aerosol matrix can be added to the liquid storage cavity 205. Exemplarily, the material of the liquid injection plug 238 is silica gel, rubber or polytetrafluoroethylene.
