[0045] The heating element 10 includes a heating element 110 , a first fixing element 120 and a second fixing element 130 .

[0046] The heating element 110 may be a linear heating unit, for example, formed by bending a heating wire along a preset trajectory; or the heating element 110 may be in a mesh shape, which may be formed by weaving linear heating wires.

[0047] The two ends of the heating element 110 are fixedly connected to the first fixing member 120 and the second fixing member 130, respectively. Specifically, the opposite ends of the heating element 110 can be respectively embedded in the first fixing member 120 and the second fixing member 130, so that the heating element 110 is fixed to the first fixing member 120 and the second fixing member 130. The middle area of ​​the heating element 110 is exposed between the first fixing member 120 and the second fixing member 130.

[0048] The area of ​​the heating element 110 between the first fixing element 120 and the second fixing element 130 is used to contact a pre-set liquid guide (such as the liquid guide cotton 140 described below). The liquid guide can contact the atomized liquid to guide the atomized liquid to the surface of the heating element 110, thereby increasing the speed at which the atomized liquid is guided to the surface of the heating element 110, improving the timeliness of the user's inhalation, and enhancing the user experience.

[0049] In this embodiment, both ends of the heating element 110 may be sintered and fixed to the first fixing element 120 and the second fixing element 130 .

[0050] Specifically, a preset powder material (or slurry) can be first used to form the blanks of the first fixing member 120 and the second fixing member 130, and then the two ends of the heating member 110 can be buried in the blanks of the first fixing member 120 and the second fixing member 130 respectively, and then heated and sintered so that the two ends of the heating member 110 can be tightly combined with the first fixing member 120 and the second fixing member 130.

[0051] Optionally, in order to improve the overall strength of the heating element 10 and reduce the manufacturing difficulty, a connecting member 150 can be further provided between the first fixing member 120 and the second fixing member 130, wherein both ends of the connecting member 150 are fixedly connected to the first fixing member 120 and the second fixing member 130 respectively.

[0052] The connecting member 150 can be sintered together with the first fixing member 120 and the second fixing member 130 at one time.

[0053] Furthermore, in this embodiment, the portion of the heating element 110 located between the first fixing element 120 and the second fixing element 130 may include a plurality of spaced heating segments 111 , and the opposite ends of each heating segment 111 are respectively connected to the first fixing element 120 and the second fixing element 130 .

[0054] The first fixing member 120 and the second fixing member 130 are respectively provided with a first through hole 121 and a second through hole 131. In this embodiment, one end of each of the plurality of heating segments 111 arranged at intervals can be arranged around the first through hole 121, and the other end of each of the plurality of heating segments 111 arranged at intervals can be arranged around the second through hole 131.

[0055] The plurality of heating segments 111 arranged at intervals may surround and form an atomizing space 101 , and the first through hole 121 and the second through hole 131 are in communication with the atomizing space 101 .

[0056] In this embodiment, one of the first through hole 121 and the second through hole 131 can be connected to the air inhalation passage, and the other of the through hole 121 and the second through hole 131 can be connected to the air inlet passage. Therefore, when the multiple heating segments 111 heat and atomize the atomized liquid, the generated aerosol can pass through the gaps between the multiple heating segments 111 and enter the atomization space 101. The user can inhale from the air inhalation passage, thereby allowing external air to enter the atomization space 101 from the air inlet passage and form an airflow, which can drive the generated aerosol to be sucked out of the air inhalation passage for consumption.

[0057] Therefore, in the solution of the present application, by pre-setting a liquid guide (such as the liquid guide cotton 140 described later) to guide the atomized liquid to the surface of the heating element 110, the flow of the atomized liquid to the surface of the heating element 110 can be accelerated, ensuring the instantaneous formation of aerosol by the atomized liquid, thereby improving the user experience. In addition, by arranging multiple spaced heating segments 111 and surrounding them, and then using a pre-set liquid guide to contact the multiple heating segments 111 to guide the atomized liquid to the surface of the multiple heating segments 111, the liquid descent rate of the atomized liquid can be increased, thereby increasing the rate of aerosol formation.

[0058] In this embodiment, when the heating element 110 is formed by bending a heating wire, the plurality of heating segments 111 are all straight segments.

[0059] Alternatively, in other embodiments, the heating element 110 may be in a mesh shape, that is, two adjacent heating segments 111 may be connected by at least one sub-heating segment 112. In this embodiment, there are multiple sub-heating segments 112, and the multiple heating segments 111 and the multiple sub-heating segments 112 may form a mesh-shaped heating element 110.

[0060] In this embodiment, optionally, part of the heating section 111 can be buried in the connector 150. The width of the connector 150 is 0.5-2 mm. Specifically, the connector 150 can be in the shape of an elongated strip and its cross section is arc-shaped, and the corresponding width of the connector 150 corresponds to the arc length of the arc. The width of the connector 150 can be 0.5, 1, 1.5 or 2 mm. In this embodiment, by limiting the width of the connector 150 to within the range of 0.5-2 mm, the contact area between the connector 150 and the liquid-conducting cotton can be reduced while ensuring the strength of the connector 150, that is, the area of ​​the multiple heating sections 111 exposed outside the connector 150 can be increased, thereby ensuring the contact area between the heating element 110 and the liquid-conducting cotton.

[0061] In other embodiments, the connecting member 150 may be a connecting tube, and a plurality of heating segments 111 may be embedded on the outside of the connecting tube, wherein a plurality of openings are provided on the connecting tube, and the aerosol formed by heating by the heating segments 111 may enter the internal space of the connecting member 150 through the openings on the connecting member 150 (in this case, the internal space of the connecting member 150 may constitute the atomization space 101 as described above).

[0062] At least two electrodes 132 are provided on the second fixing member 130; one end of each of the two electrodes 132 is connected to different positions of the heating member 110, and the other end of each of the two electrodes 132 is used to electrically connect to the positive and negative poles of an external power supply.

[0063] Optionally, the two electrodes 132 may be integrally provided with the heating element 110 , that is, the two electrodes 132 and the heating element 110 are an integral structure, and one end of the heating element 110 passes through the second fixing element 130 to form two electrodes 132 spaced apart.

[0064] Furthermore, in this embodiment, both the first fixing member 120 and the second fixing member 130 may be cylindrical (or approximately cylindrical), and their diameters may be equal. The axes of the first fixing member 120 and the second fixing member 130 may be collinear.

[0065] Alternatively, in other embodiments, the cross-sections of the first fixing member 120 and the second fixing member 130 may be elliptical, square, rectangular, etc., and the cross-sectional shapes and sizes of the two may be set to be the same.

[0066] In the above embodiment, a liquid guide is required to contact the heating section 111 between the first fixing member 120 and the second fixing member 130. For ease of installation, the liquid guide can also be directly mounted on the heating section 111 between the first fixing member 120 and the second fixing member 130.

[0067] Please refer to the following for details: Figure 1 、 Figure 3 and Figure 4 . Figure 3 This is a structural diagram of an embodiment of a heating element assembly provided by the present application; Figure 4 yes Figure 3 A cross-sectional view of the heating element assembly shown.

[0068] The heating element assembly includes a liquid-conducting sponge 140 and the heating element 10 described above. The liquid-conducting sponge 140 is annular and is mounted on the plurality of heating segments 111 between the first fixing member 120 and the second fixing member 130. Furthermore, the outer wall of the liquid-conducting sponge 140 can be configured to be flush with the side walls of the first fixing member 120 and the second fixing member 130.

[0069] Alternatively, in other embodiments, the outer side wall of the liquid-guiding cotton 140 may be configured to partially extend beyond the groove formed by the first fixing member 120 and the second fixing member 130 .

[0070] The opposite ends of the liquid-guiding cotton 140 are in contact with the first fixing member 120 and the second fixing member 130 respectively.

[0071] Furthermore, based on the same inventive concept, the present application also provides an atomizer core.

[0072] See also Figure 5 , Figure 5 This is a structural diagram of an embodiment of an atomizer core provided in this application.

[0073] The atomizer core 20 includes an atomizer core body, a liquid-conducting cotton 140 and the heating element 10 as described above. Alternatively, the atomizer core 20 includes an atomizer core body and the heating element assembly as described above.

[0074] A liquid storage chamber 201 for storing atomized liquid can be formed in the atomizer core body. The atomizer core body includes a first sleeve 210, a second sleeve 220, a first seal 230, and a second seal 240. The liquid storage chamber 201 can be formed by enclosing the sleeve 210, the second sleeve 220, the first seal 230, the second seal 240, the liquid guide cotton 140, and the heating element 10. This simplifies the structure of the atomizer core 20 and reduces installation difficulty.

[0075] The liquid storage chamber 201 has a liquid outlet, and the liquid guiding cotton 140 can be placed over the liquid outlet. The outer wall of the liquid guiding cotton 140 is arranged toward the liquid outlet of the liquid storage chamber 201, so that the liquid guiding cotton 140 can receive the atomized liquid in the liquid storage chamber 201.

[0076] Optionally, the heating element assembly formed by the liquid-conducting cotton 140 and the heating element 10 can cover the liquid outlet of the liquid storage chamber 201 , thereby preventing the atomized liquid in the liquid storage chamber 201 from leaking.

[0077] Furthermore, in this embodiment, the cross-sectional dimensions of the second sleeve 220 are greater than those of the first sleeve 210. The second sleeve 220 is sleeved onto the first sleeve 210, with the opposite ends of the second sleeve 220 respectively connected to the first seal 230 and the second seal 240. In other words, the first seal 230 and the second seal 240 can respectively cover the openings at the opposite ends of the second sleeve 220, thereby forming a housing space within which the first sleeve 210 and the heating element 10 are both located.

[0078] Furthermore, one end of the first sleeve 210 can be sleeved on the first fixing member 120 in the heating element 10 and the internal pipe of the first sleeve 210 can be connected to the atomization space 101 in the heating element 10; the other end of the first sleeve 210 is connected to the first sealing member 230, and the first sealing member 230 is provided with an air outlet 231, and the opening at the other end of the first sleeve 210 is connected to the air outlet 231.

[0079] The second fixing member 130 in the heating element 10 can be connected to the second sealing member 240. The second sealing member 240 is provided with an air inlet 241, which can be used to communicate with the outside atmosphere. When the second fixing member 130 is fixedly connected to the second sealing member 240, the second through hole 131 of the second fixing member 130 can be connected to the air inlet 241, so that the outside atmosphere can enter the atomization space 101 through the air inlet 241 and along the second through hole 131.

[0080] Therefore, the liquid-guiding cotton 140 can guide the atomized liquid in the liquid storage chamber 201 to the surface of the heating section 111, so that the atomized liquid forms aerosol, and the aerosol can be sucked out from the atomization space 101 along the inner tube of the first sleeve 210 and the air outlet 231 in sequence for the user to inhale.

[0081] Optionally, a liquid storage sponge 202 is provided in the liquid storage cavity 201, and the liquid guiding sponge 140 can be in contact with the liquid storage sponge 202. The liquid storage sponge 202 can be sponge-shaped for storing atomized liquid, and the outer contour of the liquid storage sponge 202 can match the inner wall of the liquid storage cavity 201.

[0082] Please see further Figure 5 The first sealing member 230 is provided with a boss portion 232, and the air outlet 231 can be opened on the boss portion 232. The first fixing member 120 is also provided with a protrusion 122. One end of the first sleeve 210 can be sleeved on the protrusion 122, and the other end can be sleeved on the boss portion 232.

[0083] A sealing structure may be provided at the connection between the first sleeve 210 and the protrusion 122 and the boss portion 232 to ensure the sealing performance of the liquid storage chamber 201 and prevent the liquid storage chamber 201 from leaking.

[0084] Furthermore, a first groove is provided on the side of the first sealing member 230 facing away from the second sealing member 240, in which a liquid-absorbing cotton 233 can be provided. The liquid-absorbing cotton 233 can be provided around the air outlet 231, so as to absorb the condensation of the mist at the air outlet 231, thereby avoiding leakage of condensation at the position of the air outlet 231.

[0085] Correspondingly, a liquid-absorbing cotton 242 can also be provided on the side of the second sealing member 240 away from the first sealing member 230 . The liquid-absorbing cotton 242 can absorb the condensation of the mist at the second through hole 131 , thereby preventing the condensation from leaking at the position of the second through hole 131 .

[0086] Please see further Figure 6 . Figure 6 yes Figure 5 A schematic structural diagram of another embodiment of the atomizer core is shown.

[0087] In this embodiment, the atomizer core 20 further includes an adapter 250 , which can be connected to the second sealing member 240 , wherein a second groove is provided on the side of the adapter 250 facing the second sealing member 240 , and the absorbent cotton 242 can be installed in the second groove.

[0088] Furthermore, based on the same inventive concept, the present application also provides an atomizer. Figure 7 , Figure 7 It is a structural schematic diagram of an embodiment of an atomizer provided by the present application.

[0089] The atomizer 30 includes a main body 310 and the atomizing core 20 as described above.

[0090] The main body 310 is provided with a power supply 311 , the atomizer core 20 is installed in the main body 310 , and the power supply 311 is electrically connected to the heating element 10 .

[0091] Among them, optionally, a coupled controller 312 and an air pressure detection device (not shown in the figure) are also provided in the main body 310; the controller 312 is electrically connected to the power supply 311, and the air pressure detection device is used to detect the air pressure in the first sleeve 210, and the controller 312 controls the power supply 311 to supply power to the heating element 10 when the air pressure in the first sleeve 210 reaches a preset value.

[0092] The main body 310 includes a first shell 301 and a second shell 302 that are detachably connected. The first shell 301 and the second shell 302 can be enclosed to form an installation space, and the power supply 311, the controller 312, the air pressure detection device and the atomizer core 20 are all installed in the installation space.

[0093] The power supply 311 and the controller 312 may be disposed in the first shell 301 . The end of the second shell 302 is a suction nozzle 303 . The suction nozzle 303 has an air suction channel 3031 . The air suction channel 3031 is connected to the air outlet 231 .

[0094] Therefore, the user can inhale from the mouthpiece 303 , thereby inhaling the aerosol in the atomization space 101 along the first sleeve 210 , the air outlet 231 and the air inhalation channel 3031 .

[0095] In this embodiment, by setting up the controller 312 and the air pressure detection device, when the user inhales from the mouthpiece 303, the air pressure in the first sleeve 210 and the atomization space 101 connected thereto can be reduced. According to this principle, the air pressure in the first sleeve 210 and / or the atomization space 101 is detected by the air pressure detection device. When it is detected that the air pressure in the first sleeve 210 and / or the atomization space 101 is less than a preset value, it can be indicated that the user has started the inhalation action. At this time, the air pressure detection device will send a trigger signal to the controller 312, so that the controller 312 controls the power supply 311 to supply power to the heating element 10, so that the atomized liquid is heated to form an aerosol for the user to inhale.

[0096] When the user stops inhaling, the air pressure in the first sleeve 210 and / or the atomization space 101 will return to the initial value (for example, the atmospheric pressure value). At this time, if the air pressure detection device detects that the air pressure in the first sleeve 210 and / or the atomization space 101 has returned to the initial value, a trigger signal can be sent to the controller 312, so that the controller 312 can control the power supply 311 to stop supplying power to the heating element 10.

[0097] In summary, it is easy for those skilled in the art to understand that the beneficial effects of the present application are: in the solution of the present application, by using liquid-conducting cotton and atomized liquid to guide the atomized liquid to the surface of the heating element, the rate at which the atomized liquid is guided to the surface of the heating element can be increased, the timeliness of the user's inhalation can be improved, and the user experience can be improved. In addition, liquid storage cotton is used to store the atomized liquid, and the liquid-conducting cotton is in contact with the liquid storage cotton, so that the atomized liquid stored in the liquid storage cotton can be guided to the surface of the heating element. While ensuring the rate at which the atomized liquid is guided to the surface of the heating element, the risk of leakage of the atomized liquid can also be reduced. In addition, the atomizer core structure provided by the solution of the present application is simple, and its production, processing and installation processes are simple and convenient, which can provide production efficiency.

Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
