[0026] See also Figures 1 to 3 The utility model shows an atomization device, which includes a housing 10, a mounting bracket 20, a base 30, and an atomization assembly 40.

[0027] like Figure 2 As shown, the housing 10 is provided with an air duct 11 and a liquid storage chamber 12, and the mounting bracket 20 can be roughly in the shape of a hollow column such as a hollow cylinder, or the mounting bracket 20 is in the shape of a circular tube. Of course, the mounting bracket 20 can also be in other structural shapes, which are not specifically limited here.

[0028] The atomizing assembly 40 can be installed in the inner cavity of the mounting bracket 20 and installed on the base 30 together. The mounting bracket 20 is connected and communicated with the air duct 11 , and the base 30 is installed at the open portion of the housing 10 .

[0029] See also Figures 3 to 5 The utility model shows an atomization assembly 40, which includes a liquid guide 41, a heating element 42 and a fastener 43. The liquid guide 41 is in a hollow columnar shape, such as a hollow cylindrical shape. Of course, the liquid guide 41 can also be other structural shapes. The hollow inner cavity of the liquid guide 41 can form an air guide channel for aerosol flow.

[0030] The liquid-conducting body 41 includes an inner wall and an outer wall opposite to each other, the heating element 42 includes a heating portion 421 and at least two pins 422 connected to the heating portion 421, the heating portion 421 is embedded in the inner wall of the liquid-conducting body 41, or the heating portion 421 is attached to the inner wall of the liquid-conducting body 41, and the fastener 43 is arranged on the heating portion 421 to fix the heating portion 421 to the inner wall of the liquid-conducting body 41. The material of the liquid-conducting body 41 can be a porous material with microporous capillary effect such as porous ceramic, foamed metal, porous glass or hard glass fiber tube. The heating portion 421 can be a composite material of metal material, metal alloy, graphite, carbon, conductive ceramic or other ceramic material and metal material with appropriate impedance. Further, the metal or alloy material with appropriate impedance includes at least one of nickel, cobalt, zirconium, titanium, nickel alloy, cobalt alloy, zirconium alloy, titanium alloy, nickel-chromium alloy, nickel-iron alloy, iron-chromium alloy, iron-chromium-aluminum alloy, titanium alloy, iron-manganese-aluminum-based alloy or stainless steel. Preferably, the heating portion 421 may be a heating sheet or a heating net, and its structure in a plan view may be roughly arc-shaped or C-shaped.

[0031] In some embodiments, the fastener 43 may include a reinforcing rib provided on the heating portion 421 and connected to the inner side wall of the liquid-conducting body 41, the number of the reinforcing ribs being multiple, and the multiple reinforcing ribs being arranged at intervals along the circumference of the inner side wall of the liquid-conducting body 41. The reinforcing rib may be in the shape of a long strip, and the length direction of each reinforcing rib is arranged parallel to the axial direction of the liquid-conducting body 41. The reinforcing rib may be sintered together with the inner wall surface of the liquid-conducting body 41. By reinforcing the heating portion 421 with the reinforcing rib, the heating portion 421 can be better combined with the inner wall surface of the liquid-conducting body 41, the heating portion 421 is not easy to deform and separate from the liquid-conducting body 41, and the situation where part of the structure of the heating element 42 is dry-burned is not easy to occur. Furthermore, the heating portion 421 is not easy to deform and separate from the liquid-conducting body 41, and the hollow inner cavity structure of the liquid-conducting body 41 can also be stabilized, the air-conducting channel is more stable, and the quality of the aerosol generated by the atomizing device is more stable.

[0032] like Figure 5As shown, the fastener 43 is an annular tube, and the fastener 43 can be arranged in the inner cavity of the liquid-conducting body 41, and the circumferential outer wall surface of the fastener 43 is pressed against the inner wall surface of the heating part 421. By reinforcing the heating part 421 with the fastener 43, the heating part 421 can be better combined with the inner wall surface of the liquid-conducting body 41, and the heating part 421 is not easy to deform and separate from the liquid-conducting body 41, and then it is not easy for part of the structure of the heating element 42 to dry burn. Moreover, the heating part 421 is not easy to deform and separate from the liquid-conducting body 41, which can also make the hollow inner cavity structure of the liquid-conducting body 41 stable, the air-conducting channel more stable, and the quality of the aerosol generated by the atomizing device more stable. The fastener 43 is ceramic, or foamed metal. For example, the reinforcing rib can be ceramic or foamed metal, or the reinforcing rib can be made of other metals or non-metallic materials, which are not specifically limited here.

[0033] Furthermore, the wall surface of the fastener 43 is provided with air guide holes. The fastener 43 can be roughly a hollow tubular structure, and its wall surface is provided with a plurality of air guide holes. The heating part 421 heats the atomized liquid on the liquid guide 41 to generate an aerosol, and the aerosol can enter the air guide channel through the air guide holes. The fastener 43 is ceramic or foamed metal. Of course, the fastener 43 can be made of other metal or non-metal materials, which is not specifically limited here.

[0034] In some embodiments, the fastener 43 may also be an annular tube, and the fastener 43 may be disposed in the inner cavity of the liquid-conducting body 41, and the circumferential outer wall of the fastener 43 is pressed against the inner wall of the heating portion 421. Furthermore, part of the circumferential wall of the fastener 43 is recessed toward one side of the liquid-conducting body 41 to squeeze the wall of the heating portion 421, so that part of the structure of the heating portion 421 is more tightly combined with the liquid-conducting body 41, and is less likely to deform and separate from the liquid-conducting body 41, and then it is less likely that part of the structure of the heating element 42 will dry burn, and the heating portion 421 is not likely to deform and separate from the liquid-conducting body 41, which can also make the hollow inner cavity structure of the liquid-conducting body 41 stable, the air-conducting channel more stable, and the quality of the aerosol generated by the atomizing device more stable. Preferably, the fastener 43 is ceramic, or foamed metal. For example, the reinforcing rib may be ceramic or foamed metal, or the reinforcing rib may be made of other metal or non-metal materials, which are not specifically limited here.

[0035] Understandably, the position where the heating part 421 is combined with the liquid-conducting liquid 41 is increased with concave ribs or convex points or segmented ribs, and the shape and number of the intermediate ribs are not limited, depending on the size of the heating part 421 and the liquid-conducting liquid 41. This structure can well fix the heating part 421 (or the heating element 42), ensure that the heating part 421 and the liquid-conducting liquid 41 are well combined and not easily deformed, so that when the atomizing assembly 40 performs heating and atomizing work, the atomization is smoother and dry burning is not likely to occur.

[0036] Re-read Figure 2 and Figure 3 In some embodiments, the mounting bracket 20 is provided with a plurality of liquid guide holes 21, which are connected to the liquid storage chamber 12, and the liquid guide holes 21 are arranged opposite to the liquid guide liquid 41. The atomized liquid (such as tobacco oil) in the liquid storage chamber 12 passes through the liquid guide holes 21 and enters the liquid guide liquid 41. The heating element 42 heats and atomizes the atomized liquid stored in the liquid guide liquid 41 to generate an aerosol, and the aerosol then flows into the air guide pipe through the air guide channel for consumers to enjoy.

[0037] Furthermore, there are a plurality of the liquid guiding holes 21 , and the plurality of liquid guiding holes 21 are arranged at intervals along the circumferential direction and / or axial direction of the mounting bracket 20 .

[0038] In some embodiments, the atomization device may further include a liquid guide sleeve 50, which is used to be sleeved on the circumferential outer surface of the liquid guide 41, and the liquid guide sleeve 50 is arranged opposite to the liquid guide 41. The material of the liquid guide sleeve 50 may be different from the material of the liquid guide 41. For example, the material of the liquid guide sleeve 50 may be liquid guide cotton, while the material of the liquid guide 41 may be porous ceramic, so that the speed at which the atomized liquid flows into the liquid guide sleeve 50 and the liquid guide 41 is different. The atomized liquid in the liquid storage chamber 12 first passes through the liquid guide sleeve 50 and then enters the liquid guide 41. This structure can avoid dry burning of the liquid guide 41. Of course, in other embodiments, the material of the liquid guide sleeve 50 may also be the same as that of the liquid guide 41, for example, both may be porous ceramics, which is not specifically limited here.

[0039] In some embodiments, the base 30 may be fixed with the housing 10 by interference fit, thread fixation or snap fixation. The base 30 may be made of rubber material, silicone material or other insulating material. The base 30 may be provided with a plug-in slot for mounting and fixing the lower end of the mounting bracket 20, and the base 30 may be provided with an air inlet, through which the fresh air from the outside can enter the air guide channel.

[0040] In some embodiments, a conductive column 60 is further provided on the base 30, and a pin 422 of the atomizer assembly 40 is passed through the base 30 and electrically connected to the conductive column 60. The number of the pins 422 is two, including positive and negative electrode pins, and the number of the conductive columns 60 is also correspondingly two.

[0041] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, all equivalent changes and modifications made to the scope of the claims of the utility model should fall within the scope of the claims of the utility model.
