Description

Technical Field

[0001] The present invention relates to the technical field of electronic atomization, and particularly to an atomizer. Background Art

[0002] Existing paste atomizers include a liquid storage chamber, oil guiding cotton, a porous ceramic body, and a heating wire. The paste is usually arranged in the liquid storage chamber, and the heating wire is arranged on the porous ceramic body. When the atomizer works, the paste in the liquid storage chamber is first heated to melt it. The fluidity of the melted paste is enhanced, so it is absorbed by the oil guiding cotton, and then the melted paste is conducted by the oil guiding cotton to the porous ceramic body. The heating wire heats the porous ceramic body to heat and atomize the paste on the porous ceramic body to form smoke for the user to inhale.

[0003] However, since the paste is a viscous substance and cannot flow normally at room temperature, it needs to be preheated to melt it. In the prior art, the liquid storage chamber is usually made of stainless steel, and the heat is conducted to the internal paste through the stainless steel. However, the thermal conductivity of stainless steel is relatively high and the temperature rises quickly, while the paste only needs to reach 70°C - 80°C to have good fluidity. A higher temperature will cause the flow rate of the paste to be too fast, affecting the atomization effect of the atomizer; on the other hand, the stainless steel material will also cause most of the heat to be dissipated through the stainless steel pipe, affecting the overall heating efficiency of the atomizer. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an atomizer that can solve the problems in the prior art. The atomizer can be heated as a whole, with a suitable heating temperature, a small thermal conductivity coefficient, a strong constant temperature effect, and reduced heat loss.

[0005] The present invention provides an atomizer, including a housing structure, and an oil storage body, a porous oil guiding body, and a resistive heating element installed in the housing structure. The oil storage body is provided with a first accommodation cavity for accommodating the paste and a second accommodation cavity for accommodating the porous oil guiding body. The cavity wall of the first accommodation cavity is provided with a heat radiation layer. The porous oil guiding body is in contact with or spaced from the cavity wall of the second accommodation cavity. The resistive heating element is connected to or in contact with the porous oil guiding body.

[0006] In one embodiment, the oil storage body includes a ceramic shell, a smoke guiding tube, a first sealing plate, and a second sealing plate. The smoke guiding tube is arranged in the ceramic shell. The first sealing plate and the second sealing plate are fixedly connected between the ceramic shell and the smoke guiding tube. A first accommodation cavity is formed among the first sealing plate, the second sealing plate, the ceramic shell, and the smoke guiding tube. The smoke guiding tube communicates with the second accommodation cavity.

[0007] In one embodiment, the first sealing plate is located at the top of the ceramic shell, the second sealing plate is located in the middle of the ceramic shell, and at least one oil leakage hole is provided on the second sealing plate. The oil leakage hole communicates the first accommodation cavity and the second accommodation cavity.

[0008] In one embodiment, a heat radiation layer is provided on the inner wall of the smoke guide tube and / or the outer wall of the second sealing plate.

[0009] In one embodiment, the housing structure includes an outer shell, a mouthpiece, and a base. One end of the outer shell is connected to the mouthpiece, and the other end of the outer shell is connected to the base. The mouthpiece is in communication with the smoke guide tube. The bottom of the oil storage body is disposed on the base, and the resistance heating element is connected to the base.

[0010] In one embodiment, the base is provided with a first carrier and a second carrier. The first carrier and the second carrier are oppositely disposed. The resistance heating element is located between the first carrier and the second carrier, and the bottom of the porous oil guiding body is disposed on the first carrier and the second carrier.

[0011] In one embodiment, the end faces of the first carrier, the second carrier in contact with the porous oil guiding body are arc-shaped.

[0012] In one embodiment, an air passage is formed between the oil storage body and the inner wall of the outer shell. The base is provided with an air inlet hole, and the air passage is in communication with the mouthpiece and the air inlet hole.

[0013] In one embodiment, the resistance heating element includes a first connecting portion, a second connecting portion, and an atomizing portion connected between the first connecting portion and the second connecting portion. The first connecting portion and the second connecting portion are connected to the base, and the atomizing portion is connected to or in contact with the porous oil guiding body.

[0014] In one embodiment, the housing structure further includes a first electrode and a second electrode. The first electrode and the second electrode are mounted on the base. The first electrode is electrically connected to the first connecting portion, and the second electrode is electrically connected to the second connecting portion.

[0015] The atomizer of the present invention utilizes the characteristic that the ceramic thermal conductivity is smaller than that of metal. The tobacco paste is placed in the first accommodating cavity of the oil storage body for preheating. After the heat radiation layer in the first accommodating cavity absorbs heat, it radiates to preheat the whole oil storage body evenly. The preheated oil flows to the porous oil guiding body in the second accommodating cavity for atomization. When heat is transferred through the oil storage body, the constant temperature effect is stronger than that of a stainless steel tube, and the heat loss is smaller, improving the atomization effect of the atomizer, prolonging the service life of the atomizer, and enhancing the user experience.

[0026] Figure 1 It is a schematic diagram of the disassembled structure of the atomizer according to the first embodiment of the present invention, Figure 2 It is a schematic diagram of the sectional structure of the atomizer according to the first embodiment of the present invention, as Figure 1 andFigure 2 As shown in the figure, the atomizer includes a housing structure 11, and an oil storage body 12, a porous oil guiding body 13, and a resistance heating element 14 installed in the housing structure 11. The oil storage body 12 is provided with a first accommodating cavity 101 for accommodating the tobacco paste and a second accommodating cavity 102 for accommodating the porous oil guiding body 13. The cavity wall of the first accommodating cavity 101 is provided with a heat radiation layer 15. The porous oil guiding body 13 is in contact with or spaced from the cavity wall of the second accommodating cavity 102. The resistance heating element 14 is connected to or in contact with the porous oil guiding body 13. In this embodiment, the heat generated by the resistance heating element 14 is transferred to the porous oil guiding body 13, and the e-liquid in the porous oil guiding body 13 is heated and atomized to generate an aerosol at a relatively high temperature. After the heat radiation layer 15 absorbs the heat of the aerosol, it radiates the heat to the oil storage body 12, realizing the overall uniform preheating of the oil storage body 12. Since the oil storage body 12 has a high thermal conductivity coefficient, the oil storage body 12 has a fast heat conduction speed and a good constant temperature effect. The tobacco paste only needs to reach 70°C to 80°C to have good fluidity. Therefore, the temperature is appropriate, and the surface of the atomizer will not have a high temperature touch. The material of the oil storage body 12 is, for example, a heat-conducting ceramic material, aluminum nitride, alumina, or a ceramic structure formed by a mixture of the two, but is not limited thereto.

[0027] The atomizer of the present invention utilizes the characteristic that the thermal conductivity coefficient of ceramics is smaller than that of metals. The tobacco paste is placed in the first accommodating cavity 101 of the oil storage body 12 for preheating. After the heat radiation layer 15 in the first accommodating cavity 101 absorbs heat, it radiates the heat to the oil storage body 12 for overall preheating. The temperature is uniform. The preheated oil flows to the porous oil guiding body 13 in the second accommodating cavity 102 for atomization. When conducting heat through the oil storage body 12, the constant temperature effect is stronger than that of a stainless steel tube, and the heat loss is smaller, improving the atomization effect of the atomizer, prolonging the service life of the atomizer, and improving the user experience.

[0028] Further, the housing structure 11 includes an outer shell 111, a mouthpiece 112, and a base 113. One end of the outer shell 111 is connected to the mouthpiece 112.

The oil storage body 12 is fixedly connected to the outer shell 111 or detachably connected by means of a cooperation of a snap and a slot. The bottom of the oil storage body 12 is arranged on the base 113. The resistance heating element 14 is connected to the base 113. Among them, the outer shell 111 is a tubular hollow structure. The material of the housing structure 11 is, for example, ABS plastic, PC plastic, a mixture of PC and ABS, a glass fiber reinforced material, or a carbon fiber composite material, etc. The mouthpiece 112 is made of one or more materials such as polylactic acid or polybutylene succinate, but is not limited thereto.

The first sealing plate 123 and the second sealing plate 124 are fixedly connected between the ceramic shell 121 and the smoke guide tube 122. A first accommodating cavity 101 is formed among the first sealing plate 123, the second sealing plate 124, the ceramic shell 121 and the smoke guide tube 122, and the smoke guide tube 122 communicates with a second accommodating cavity 102.

The first sealing plate 123 is provided with a first through hole 107, and the first through hole 107 communicates the cigarette holder 112 and the flue 106. The second sealing plate 124 is provided with a second through hole 108, and the second through hole 108 communicates the flue 106 and the second accommodating cavity 102. The smoke guide tube 122 is made of one or a combination of aluminum nitride, alumina, etc. The ceramic shell 121 is made of one or a combination of aluminum nitride, alumina, etc., but is not limited thereto.

[0030] As Figure 2 shown, the first sealing plate 123 is located at the top of the ceramic shell 121, the second sealing plate 124 is located in the middle of the ceramic shell 121.

When passing through the flue 106, the heat is absorbed by the heat radiation layer 15 at the smoke guide tube 122 for preheating the tobacco paste, so that the atomizer preheats and melts the tobacco paste while in use, rather than having to completely melt the tobacco paste before use; it should be noted that the position where the radiation layer 15 is provided can be a combination of one or more of the above embodiments, but not limited thereto.

[0037] As Figure 2As shown, an air passage 104 is formed between the oil storage body 12 and the inner wall of the outer shell 111. The base 113 is provided with an air inlet hole 105.

[0040] The atomization process of the atomizer is as follows: The electrode is energized to heat the resistance heating element 14. After the resistance heating element 14 is heated, heat conduction is carried out through the porous oil guiding body 13. After the second sealing plate 124 absorbs heat, it preheats the tobacco paste. The heat radiation layer 15 absorbs the heat of the porous oil guiding body 13 through the way of aerosol heat conduction and then radiates it to the oil storage body 12. The oil storage body 12 preheats the tobacco paste in the first accommodating cavity 101. The preheated tobacco paste becomes a fluid oil liquid and leaks through the oil leakage hole 103 to the porous oil guiding body 13 in the second accommodating cavity 102.
