[0029] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0030] like Figure 1 and Figure 2 As shown, in one embodiment, a heating element 120 is provided, which is applied to the atomizer core 100. The heating element 120 includes a first power connection portion 121, a second power connection portion 122 and a heating portion 123. The first power connection portion 121 and the second power connection portion 122 are arranged at intervals and can be bent to form a ring structure. There are at least two heating portions 123, and each heating portion 123 is connected in parallel between the first power connection portion 121 and the second power connection portion 122.

[0031] When the heating element 120 in the above embodiment is used, the first power connection portion 121 and the second power connection portion 122 are bent to form a ring-shaped structure, and then the first power connection portion 121 and the second power connection portion 122 are placed outside the liquid guide member 110, so that the heating element 120 can be installed in the air flow channel 230 through the liquid guide member 110. When it is necessary to atomize the aerosol matrix, the first power connection portion 121 and the second power connection portion 122 are energized to the heating portion 123. The heating portion 123 generates heat and transfers the heat to the aerosol matrix through the liquid guide member 110. The aerosol matrix heats up and is atomized and discharged with the gas in the air flow channel 230, achieving the atomization effect. Compared with the electronic atomizer in the prior art, the heating element 120 in the present application has at least the following advantages: 1. The heating element 120 can be pre-assembled with the liquid guide part 110 to form a whole, and then the heating element 120 can be suspended in the air flow channel 230 through the liquid guide part 110 to ensure that the heating element 120 and the liquid guide part 110 are in firm contact when assembled, and the heating element 120 will not be deformed due to over-tight wrapping, thereby improving the convenience of assembling the heating element 120. 2. Multiple heating parts 123 are connected in parallel to ensure that when one of the multiple heating parts 123 is damaged, the other heating parts 123 can all work normally, thereby improving the practicality and service life of the atomizer core 100. 3. Multiple heating parts 123 share a first power connection part 121 and a second power connection part 122, which facilitates the processing and manufacturing of the heating element 120 while also facilitating the electrical connection between the heating element 120 and the battery.

[0032] The parallel connection of the heating elements 123 between the first power connection 121 and the second power connection 122 means that the heating elements 123 are located between the first power connection 121 and the second power connection 122, one side of each heating element 123 is electrically connected to the first power connection 121, and the other side of each heating element 123 is electrically connected to the second power connection 122, with an interval between adjacent heating elements 123. The number of heating elements 123 can be flexibly adjusted according to actual needs.

[0033] It should be noted that the heating element 120 may be a sheet-like structure during manufacture and may be bent into a ring-like structure during assembly.

[0034] like Figure 1 and Figure 2As shown, optionally, the first power connection portion 121 and the second power connection portion 122 each include a first connecting section 1211, a mounting section 1212, and a second connecting section 1213 connected in sequence. The mounting section 1212 can be bent to form a ring structure. Each heating portion 123 is connected in parallel between the two mounting sections 1212. The first connecting section 1211 and the second connecting section 1213 can be attached to form a pin structure when the mounting section 1212 is bent to form a ring structure. In this way, the heating element 120 can be fixed to the liquid guide member 110 as a whole, improving the reliability of the atomizer core 100.

[0035] Specifically in this embodiment, the first power connection portion 121, the second power connection portion 122, and each heating portion 123 are an integrated structure, that is, the heating element 120 is a whole unit that can be wrapped around the outside of the liquid guide 110 through processes such as bending and pressing. The two mounting sections 1212 are electrically connected to the corresponding batteries through two pin structures.

[0036] like Figure 2 and Figure 3 As shown, in one embodiment, an atomizer core 100 is provided, including a liquid guide member 110 and a heating member 120 in any of the above embodiments. The liquid guide member 110 is used to guide the aerosol matrix to the liquid guide member 110. The liquid guide member 110 is accommodated in an annular structure and contacts the heating portion 123.

[0037] When the atomizer core 100 in the above embodiment is used, the liquid guide 110 is installed in the air flow channel 230, so that the heating element 120 on the liquid guide 110 is located in the middle of the air flow channel 230, and the liquid guide 110 guides the aerosol substrate on the liquid storage element 300 to the liquid guide 110. When the aerosol substrate needs to be atomized, the first power connection 121 and the second power connection 122 are energized to the heating element 123. The heating element 123 generates heat and transfers the heat to the aerosol substrate through the liquid guide 110. The aerosol substrate heats up and is atomized and discharged with the gas in the air flow channel 230, achieving the atomization effect.

[0038] It should be noted that when the heating element 120 is suspended in the middle of the air flow channel 230 through the liquid guide 110, the space on both sides of the heating element 120 along the radial direction of the air flow channel 230 can be used for gas circulation.

[0039] like Figure 2 As shown, optionally, each heating portion 123 is attached to the outer wall of the liquid guide 110. In this way, the heat transfer area between the heating element 120 and the liquid guide 110 is increased, so that the heat transfer of the liquid guide 110 is increased to increase the atomization rate of the aerosol matrix and improve the atomization effect of the atomizer core 100.

[0040] like Figure 2As shown, optionally, at least two heating portions 123 are located on opposite sides of the liquid guide 110. In this way, the heating portions 123 on opposite sides of the liquid guide 110 can fully contact the airflow in the airflow channel 230, so that the airflow can promptly carry away the aerosol matrix atomized at the heating portions 123, thereby improving the atomization effect of the atomizer core 100.

[0041] Specifically in this embodiment, each heating element 120 is located on two opposite sides of the liquid guiding element 110 along the radial direction of the air flow channel 230 .

[0042] like Figure 2 As shown, optionally, there are two heating parts 123, along the flow direction of the aerosol matrix after atomization (such as Figure 2 In the direction shown by A in FIG, the length of the liquid guide 110 is the same as the length of the heating portion 123. In this way, a large contact area can be maintained between the heating portion 123 and the liquid guide 110, thereby increasing the heating uniformity of the aerosol matrix on the liquid guide 110 and improving the atomization effect of the atomizer core 100.

[0043] like Figure 2 As shown, optionally, the inner contour of the annular structure is adapted to the outer contour of the liquid guide 110. In this way, the heating element 120 and the liquid guide 110 can be assembled as one, thereby improving the reliability of the atomizer core 100.

[0044] like Figure 2 、 Figure 3 and Figure 4 As shown, in one embodiment, an atomizer 10 is provided, comprising a mounting housing 210 and an atomizer core 100 according to any of the above-described embodiments. A liquid reservoir 220 and an air flow channel 230 are disposed within the mounting housing 210. A heating element 123 is located within the air flow channel 230. The liquid reservoir 220 is used to store aerosol substrate. A liquid guide 110 at least partially extends from the liquid reservoir 220 to direct the aerosol substrate to the liquid guide 110.

[0045] When the atomizer 10 in the above embodiment is used, the liquid guide 110 is installed in the air flow channel 230, so that the heating element 120 on the liquid guide 110 is located in the middle of the air flow channel 230, and the liquid guide 110 is able to guide the aerosol substrate in the liquid storage tank 220 to the liquid guide 110. When the aerosol substrate needs to be atomized, the heating element 123 is energized through the first power connection 121 and the second power connection 122. The heating element 123 generates heat and transfers the heat to the aerosol substrate through the liquid guide 110. The aerosol substrate heats up and is atomized and discharged with the gas in the air flow channel 230, achieving the atomization effect.

[0046] It should be noted that the liquid storage tank 220 can directly store the aerosol matrix, or it can store the liquid storage member 300 that has adsorbed the aerosol matrix. Specifically, in this embodiment, the liquid storage member 300 is configured as a liquid storage cotton, which is stored in the liquid storage tank 220. When the liquid guide member 110 is installed in the airflow channel 230, the liquid guide member 110 contacts the liquid storage cotton, thereby directing the aerosol matrix on the liquid storage cotton to the liquid guide member 110.

[0047] like Figure 4 and Figure 5 As shown, further, the atomizer 10 also includes a bracket 240, which is arranged in the mounting shell 210 to separate the interior of the mounting shell 210 into a liquid storage tank 220 and an air flow channel 230. The bracket 240 is provided with a first mounting hole 241 and a second mounting hole 242 that connect the liquid storage tank 220 and the air flow channel 230. The liquid guide 110 has a first end 111 and a second end 112 that are arranged opposite to each other, and the first end 111 and the second end 112 are respectively penetrated by the first mounting hole 241 and the second mounting hole 242. In this way, by providing the first mounting hole 241 and the second mounting hole 242, the connection strength between the liquid guide 110 and the bracket 240 is increased, ensuring that the heating element 120 can be suspended in the middle position of the air flow channel 230, thereby improving the reliability of the atomizer 10. In addition, the first end 111 and the second end 112 are respectively penetrated by a first mounting hole 241 and a second mounting hole 242, and both extend into the liquid storage tank 220, so that the contact area between the liquid guide member 110 and the liquid storage member 300 is increased, and the aerosol matrix on the liquid guide member 110 is more evenly distributed, thereby improving the atomization effect of the nebulizer 10.

[0048] Specifically in this embodiment, the liquid storage tank 220 is provided in a ring shape, and the bracket 240 is provided in a cylindrical state. The first mounting hole 241 and the second mounting hole 242 are respectively located on two opposite sides of the bracket 240.

[0049] like Figure 4 and Figure 5 As shown, optionally, the first mounting hole 241 and the second mounting hole 242 are both notches with openings facing upwards, so as to facilitate the insertion and installation of the liquid guide member 110 and improve the convenience of assembling the atomizer 10.

[0050] like Figure 4 and Figure 5As shown, in one embodiment, the nebulizer 10 further includes a glass fiber tube 250. The glass fiber tube 250 is sleeved on the bracket 240 along a first direction and is engaged with the liquid guide member 110 in a position-limiting manner. The first direction is opposite to the flow direction of the aerosol matrix after atomization. In this way, the first end 111 and the second end 112 of the liquid guide member 110 can be placed in the first mounting hole 241 and the second mounting hole 242 respectively, and then the glass fiber tube 250 can be sleeved on the bracket 240 accordingly to achieve a position-limited fixation of the liquid guide member 110 on the bracket 240, thereby improving the convenience of assembling the nebulizer 10.

[0051] like Figure 4 and Figure 5 As shown, optionally, the mounting housing 210 is provided with a third mounting hole 211 and a fourth mounting hole 212 that are interconnected, the inner diameter of the third mounting hole 211 being larger than the inner diameter of the fourth mounting hole 212, the fiberglass tube 250 being located in the third mounting hole 211, the bracket 240 at least partially extending from the third mounting hole 211, and the atomizer 10 further comprising a sealing member 260 located at an end of the third mounting hole 211 away from the fourth mounting hole 212, so that the inner wall of the third mounting hole 211, the fiberglass tube 250, the bracket 240, and the sealing member 260 enclose and form the liquid storage tank 220. In this way, the atomizer 10 is a detachable structure, which improves the convenience of installation and maintenance of the atomizer 10.

[0052] Specifically in this embodiment, the sealing member 260 can be configured as sealing silica gel. The axis of the air flow channel 230 and the axis of the liquid storage tank 220 are located on the same straight line. Specifically in this embodiment, the sealing member 260 includes a first sealing portion and a second sealing portion. Along the radial direction of the air flow channel 230, the outer diameter of the first sealing portion is smaller than the outer diameter of the second sealing portion. The inner diameter of the first sealing portion is larger than the inner diameter of the second sealing portion. The first sealing portion is filled between the inner side wall of the third mounting hole 211 and the outer side wall of the bracket 240 to seal the inner side wall of the first mounting groove with the outer side wall of the bracket 240. The second sealing portion is located outside the third mounting hole 211 and is sealed with the end face of the mounting shell 210 and the end face of the bracket 240. In this way, it is ensured that the aerosol matrix in the liquid storage tank 220 will not leak from the connection gap between the mounting member and the bracket 240, thereby improving the reliability of the atomizer 10.

[0053] like Figure 3 and Figure 5 As shown, specifically in this embodiment, the first power connection portion 121 and the second power connection portion 122 both extend out of the air flow channel 230. In this way, the first power connection portion 121 and the second power connection portion 122 both extend out of the mounting housing 210 to facilitate electrical connection with the battery.

[0054] Specifically in this embodiment, the first power connection portion 121 and the second power connection portion 122 are both spaced apart from the inner wall of the air flow channel 230 .

[0055] In one embodiment, an atomizing device is further provided, comprising the atomizer 10 in any of the above embodiments. In this way, the atomizing device has all the technical effects of the above atomizer 10, and improves the reliability and atomizing effect of the atomizing device.
