[0009] Optionally, in some embodiments of the present application, a sealing assembly is further included. The sealing assembly includes a sealing rod, a first seal, and a second seal. The first seal and the second seal are spaced apart along the length direction of the air flow channel and are arranged in the air flow channel. The sealing rod is detachably installed in the air flow channel and is respectively inserted and connected with the first seal and the second seal to form an atomization sealing cavity between the first seal and the second seal, and the atomization assembly is arranged in the atomization sealing cavity.

[0010] Optionally, in some embodiments of the present application, the first seal has a first annular elastic portion. The sealing rod is detachably installed in the air flow channel, and the sealing rod is in interference fit with the first annular elastic portion by insertion to seal the first end of the atomization sealing cavity;

[0011] The second seal has a second annular elastic body. When the sealing rod is detachably installed in the air flow channel, the sealing rod is in interference fit with the second annular elastic body by insertion to seal the second end of the atomization sealing cavity.

[0012] Optionally, in some embodiments of the present application, at least one liquid outlet is formed in the circumferential side wall of the atomization sealing cavity, and each liquid outlet is communicated with the liquid storage cavity. The atomization assembly blocks all the liquid outlets, so that the atomization assembly is in liquid communication with the liquid storage cavity.

[0013] Optionally, in some embodiments of the present application, the atomization assembly includes a liquid guide cotton. The liquid guide cotton blocks all the liquid outlets, and the liquid guide cotton is provided with a through hole extending along the length direction of the air flow channel;

[0014] When the sealing rod is detachably installed in the air flow channel, the sealing rod passes through the liquid guide cotton through the through hole, and the liquid guide cotton is clamped between the sealing rod and the circumferential side wall of the atomization sealing cavity.

[0015] Optionally, in some embodiments of the present application, a first electrode assembly is further included.

At the same time, the first outer shell of the soft rubber structure layer only covers the surface of the first end of the inner shell of the transparent hard rubber structure layer (that is, the end of the inner shell with the air flow outlet of the air flow channel). It can not only form an observation window on the surface of the second end of the inner shell (that is, the part of the inner shell far from the air flow outlet of the air flow channel and not covered by the first outer shell), so that the user can know the liquid storage situation of the liquid storage cavity at any time, but also form a mouthpiece part wrapped by the soft rubber structure layer at the first end of the inner shell. By using the better skin-friendly property of the soft rubber structure compared with the hard rubber structure, the mouthpiece part has a better suction taste, thereby effectively improving the user experience. It can be seen that this technical solution can improve the housing of the existing electronic atomizer. Its two-color injection molding structure belongs to the combination of two hard rubbers, and it is easy to have appearance defects such as flushing, bubbles, and deformation during the production process, resulting in a low yield of the product.

[0029] In one embodiment, as Figures 1 to 3As shown in the figure, an embodiment of the present application provides an electronic atomizer 100, which includes a housing assembly 110 and an atomization assembly 120. Specifically, the housing assembly 110 may include an inner shell 111 having an air flow channel 1111, a first outer shell 112, and a base 113. The inner shell 111 is a transparent hard rubber structure layer, and the first outer shell 112 is a soft rubber structure layer. The first outer shell 112 and the inner shell 111 are an integrated structure made by two-color injection molding process. The first outer shell 112 covers the surface of the first end of the inner shell 111, so that the first end of the inner shell 111 forms a mouthpiece portion, and an observation window is formed on the surface of the second end of the inner shell 111. The base 113 is installed at the end of the second end of the inner shell 111, and a liquid storage cavity 1113 is formed between the base 113 and the inner wall of the inner shell 111. The first end of the inner shell 111 is the end of the air flow outlet 11 of the inner shell 111 having the air flow channel 1111, and the second end of the inner shell 111 is the end of the inner shell 111 away from the air flow outlet 11 of the air flow channel 1111. The atomization assembly 120 is specifically installed at one end of the air flow channel 1111 away from the air flow outlet 11 and is in liquid communication with the liquid storage cavity 1113. The atomization assembly 120 heats and atomizes the liquid in the liquid storage cavity 1113 to form an aerosol.

[0030] It can be understood that the electronic atomizer 100 mentioned in the embodiment of the present application is mainly applied to the electronic atomization device 1. Generally, in addition to including the electronic atomizer 100, the electronic atomization device 1 also includes a power supply main body 200 for supplying power to the electronic atomizer 100, so that the electronic atomization device 1 can store liquid through the electronic atomizer 100, and under the power supply of the power supply main body 200, convert the stored liquid (specifically, it can be an atomization liquid such as e-liquid) into an aerosol and spray it out for the user to inhale. The above-mentioned integrated structure of the first outer shell 112 and the inner shell 111 made by two-color injection molding process specifically means that after the inner shell 111 is injection-molded by a hard rubber material in the first shot, the first outer shell 112 is re-injection-molded on the surface of the air flow outlet 11 of the inner shell 111 having the air flow channel 1111 by a soft rubber material in the second shot, so that the first outer shell 112 and the inner shell 111 form a corresponding integrated structure. In addition, the above-mentioned liquid communication between the atomization assembly 120 and the liquid storage cavity 1113 specifically means that the liquid outlet of the liquid storage cavity 1113 is correspondingly arranged for the atomization assembly 120, so that the liquid in the liquid storage cavity 1113 can flow through the liquid outlet to the atomization assembly 120, so that the atomization assembly 120 remains moist or semi-moist.

[0031] In this way, the electronic atomizer 100 provided by the embodiments of the present application, through the above structural settings, enables the housing assembly 110 of the electronic atomizer 100 to be mainly a two-color injection molding structure in which the first outer shell 112 of the soft rubber structure layer is combined with the inner shell 111 of the transparent hard rubber structure layer. Furthermore, compared with the existing combination of two hard rubbers, the combination of soft rubber and hard rubber in the present application can achieve the full combination of the two materials without problems such as melting, air bubbles, and deformation during the production process, resulting in a significant increase in the product yield. At the same time, the first outer shell 112 of the soft rubber structure layer only covers the surface of the first end of the inner shell 111 of the transparent hard rubber structure layer (i.e., the end of the inner shell 111 with the air outlet 11 of the air flow channel 1111). It can not only form an observation window on the surface of the second end of the inner shell 111 (i.e., the part of the inner shell 111 away from the air outlet 11 of the air flow channel 1111 that is not covered by the first outer shell 112), so as to facilitate the user to know the liquid storage situation of the liquid storage cavity 1113 at any time, but also form a mouthpiece part wrapped by the soft rubber structure layer at the first end of the inner shell 111. By utilizing the better skin-friendly property of the soft rubber structure compared with the hard rubber structure, the mouthpiece part can have a better suction taste, thereby effectively improving the user experience.

[0032] In some examples, such as Figures 1 to 3 shown, the transparent hard rubber structure layer can specifically be a PCTG structure layer, and the soft rubber structure layer can specifically be a TPU structure layer. Since the corrosion resistance of the PCTG structure layer is better than that of the existing PC structure layer, and the skin-friendly property and feel of the TPU structure layer are also far better than those of the existing ABS structure layer. In this way, through the above structural settings, the housing assembly 110 of the present application can better meet the liquid storage requirements of its liquid storage cavity 1113 and make its mouthpiece part have a better suction taste, thereby effectively improving the user experience.

[0033] It can be understood that the material of the PCTG structure layer in this example can specifically be any one of PCTG-TX1501, PCTG-TX1101, and TX2001, and preferably can be PCTG-TX1501. The material of the TPU structure layer in this example can specifically be any one of TPU-E375280AV-78N, TPU-9580, TPU-LY, and TPU-E275-5, and preferably can be TPU-E375280AV-78N.

[0034] In some examples, such as Figures 1 to 3As shown, an arc-shaped groove 1112 is recessed in the top side end face of the first outer shell 112. An air vent is formed at the bottom of the arc-shaped groove 1112, and the air vent is correspondingly communicated with the air outlet 11 of the air flow channel 1111. In this way, by arranging the air vent at the bottom of the arc-shaped groove 1112, the flow mode of the aerosol near the air vent can be effectively optimized, so as to provide a more gentle and comfortable suction taste for the user.

[0035] In some examples, such as Figures 1 to 3 As shown, the electronic atomizer 100 further includes a sealing assembly 130. The sealing assembly 130 includes a sealing rod (not shown), a first sealing member 131 and a second sealing member 132. The first sealing member 131 and the second sealing member 132 are arranged at intervals in the air flow channel 1111 along the length direction of the air flow channel 1111. The sealing rod is detachably installed in the air flow channel 1111 and is respectively inserted and connected with the first sealing member 131 and the second sealing member 132 to form an atomization sealing cavity between the first sealing member 131 and the second sealing member 132. The atomization assembly 120 is arranged in the atomization sealing cavity. In this way, through the above structural arrangement, during the transportation of the product, the sealing rod can be detachably installed in the air flow channel 1111 and is respectively inserted and connected with the first sealing member 131 and the second sealing member 132 to form an atomization sealing cavity between the first sealing member 131 and the second sealing member 132, so as to seal and protect the atomization assembly 120 that is in liquid communication with the liquid storage cavity 1113. In this way, since the atomization sealing cavity does not directly seal and protect the liquid outlet hole of the liquid storage cavity 1113, even if the liquid storage cavity 1113 leaks due to reasons such as thermal expansion and contraction and air pressure change, it only penetrates into the atomization assembly 120 that is in liquid communication with the liquid storage cavity 1113 and is sealed and protected by the atomization sealing cavity, rather than leaking to the outside of the product, that is, it will not contact the air, resulting in problems such as volatilization, oxidation or taste change that affect the quality of the liquid in the liquid storage cavity 1113. At the same time, since the atomization assembly 120 always maintains liquid communication with the liquid storage cavity 1113, therefore, there will be no problem that the liquid outflow of some products lags behind at the beginning of use, affecting the atomization effect of the atomization assembly 120.

[0036] It can be understood that when the electronic atomizer 100 is in use, the sealing rod should be pulled out from the air flow channel 1111, so that the two ends of the atomization sealing cavity are no longer in a sealed state. Furthermore, the atomization sealing cavity can, on the one hand, be communicated with the air inlet of the housing assembly 110 to introduce fresh gas, and on the other hand, be communicated with the air outlet 11 of the air flow channel 1111 to discharge the aerosol formed in the atomization sealing cavity for the user to suck and use.

[0037] In some examples, such as Figures 1 to 3As shown, the first seal 131 has a first annular elastic part. The sealing rod is detachably installed in the air flow channel 1111, and the sealing rod is in interference fit with the first annular elastic part in an insertion manner to seal the first end of the atomization sealing cavity. In this way, through the above structural arrangement, the connection between the sealing rod and the first seal 131 can be made closer, and thus the sealing performance of the first end of the atomization sealing cavity can be better ensured. Similarly, the second seal 132 has a second annular elastic body. When the sealing rod is detachably installed in the air flow channel 1111, the sealing rod is in interference fit with the second annular elastic body in an insertion manner to seal the second end of the atomization sealing cavity. In this way, through the above structural arrangement, the connection between the sealing rod and the second seal 132 can be made closer, and thus the sealing performance of the second end of the atomization sealing cavity can be better ensured.

[0038] It can be understood that the above-mentioned first annular elastic part and second annular elastic part can specifically be of a silicone structure. At the same time, the inner diameter of the inner peripheral side thereof should be smaller than the outer diameter of the sealing rod, so that the sealing rod can be in interference fit with them respectively in an insertion manner. After the sealing rod is in interference fit with them respectively, the elastic restoring force generated after the silicone structure is extruded is utilized to make the sealing rod fit tightly with them respectively to ensure the sealing performance of the corresponding end of the atomization sealing cavity.

[0039] In some examples, as Figures 1 to 3 shown, at least one liquid outlet is provided on the circumferential side wall of the atomization sealing cavity, and each liquid outlet is communicated with the liquid storage cavity 1113. The atomization assembly 120 blocks all the liquid outlets, so that the atomization assembly 120 is in liquid communication with the liquid storage cavity 1113. In this way, through the above structural arrangement, while ensuring that the atomization assembly 120 is better in liquid communication with the liquid storage cavity 1113, by the atomization assembly 120 blocking all the liquid outlets, the liquid in the liquid storage cavity 1113 can be simply blocked from flowing outwards to ensure that all the liquid in the liquid storage cavity 1113 does not flow into the atomization sealing cavity unobstructedly, and further ensure the sealing performance of the atomization sealing cavity for the liquid in the liquid storage cavity 1113. Further, two liquid outlets are provided on the circumferential side wall of the atomization sealing cavity, and the two liquid outlets are arranged oppositely along the radial direction of the air flow channel 1111. In this way, through the above structural arrangement, the liquid in the liquid storage cavity 1113 can penetrate more evenly into the entire atomization assembly 120 to improve the atomization effect of the atomization assembly 120.

[0040] In some examples, as Figures 1 to 3As shown, the atomization assembly 120 includes a liquid guide cotton, which blocks all liquid outlets, and the liquid guide cotton is provided with a through hole extending along the length direction of the air flow channel 1111. When the sealing rod is detachably installed in the air flow channel 1111, the sealing rod passes through the liquid guide cotton through the through hole, and the liquid guide cotton is clamped between the sealing rod and the circumferential side wall of the atomization sealing cavity. In this way, through the above structural arrangement, the dense structure formed by the liquid guide cotton being jointly extruded by the sealing rod and the circumferential side wall of the atomization sealing cavity can be used to form a good sealing effect on the liquid outlet. When the atomization sealing cavity is in a sealed state, the flow rate of the liquid in the liquid storage cavity 1113 flowing into the atomization sealing cavity is greatly reduced and only a small amount of the liquid in the liquid storage cavity 1113 flows into the atomization sealing cavity, thereby further ensuring the sealing performance of the atomization sealing cavity for the liquid in the liquid storage cavity 1113. At the same time, when the sealing rod is pulled out, the liquid guide cotton can quickly return to a fluffy state, so that the liquid in the liquid storage cavity 1113 quickly flows to the liquid guide cotton in the atomization sealing cavity to improve the atomization effect of the atomization assembly 120. Further, the aperture of the through hole is smaller than the outer diameter of the sealing rod. In this way, through this structural arrangement, it can be ensured that when the sealing rod passes through the liquid guide cotton through the through hole, the above-mentioned dense structure is better formed. Furthermore, the aperture of the through hole is 1 mm to 3 mm smaller than the outer diameter of the sealing rod to ensure that the above-mentioned dense structure formed can better block the liquid outlet.

[0041] In some examples, as Figures 1 to 3 shown, the electronic atomizer 100 further includes a first electrode assembly, and the first electrode assembly is arranged on the base 113. The atomization assembly 120 further includes a heating element, and the heating element is electrically connected to the first electrode assembly. It can be understood that the first electrode assembly may specifically include two electrodes, and the two electrodes are respectively embedded and assembled on the base 113 and have parts exposed on the surface of the base 113 to facilitate their electrical connection with the power supply body 200. The heating element may specifically be arranged on the heat-conducting cotton to better heat the liquid on the heat-conducting cotton. In this way, through the above structural arrangement, after the electronic atomizer 100 is assembled on the corresponding power supply body 200, it can be electrically connected to the power supply body 200 through the electrode assembly. Under the operation of the power supply body 200, the heating element heats the liquid guide cotton to convert the liquid of the liquid guide cotton into aerosol and spray it out for the user to inhale.

[0042] In one embodiment, as Figures 1 to 3 shown, the embodiment of the present application further provides an electronic atomization device 1. The electronic atomization device 1 may specifically include a power supply body 200 and the electronic atomizer 100 of the above embodiment. The power supply body 200 is plugged and connected to the second end of the inner shell 111, and the power supply body 200 is electrically connected to the first electrode assembly.

[0043] In this way, since the electronic atomization device 1 of this embodiment adopts the atomizer 100 of the above embodiment, it has the same structure, function and technical effects as the atomizer 100 of the above embodiment, which will not be elaborated here. In addition, since the power supply body 200 of this electronic atomization device 1 and the atomizer 100 adopt a plug-in connection method, users can disassemble, install and replace the atomizer 100 or the power supply body 200 at any time according to actual needs.

[0044] In some examples, as Figures 1 to 3 shown, the power supply body 200 includes a power supply module 210 and a second outer shell 220 having a plug-in slot 221 and a receiving chamber 222. The power supply module 210 is installed in the receiving chamber 222 and is electrically connected to the first electrode assembly when the second end of the inner shell 111 is inserted into the plug-in slot 221. In this way, through the above structural arrangement, the second outer shell 220 can cooperate with the first outer shell 112 to form a flat structural surface, effectively improving the structural appearance of the product. At the same time, the second outer shell 220 can also play a good role in surrounding and protecting the part of the inner shell 111 of the atomizer 100 that is not covered by the first outer shell 112.

[0045] In some examples, as Figures 1 to 3 shown, the inner wall of the plug-in slot 221 and the outer surface of the inner shell 111 are tightly connected through a buckle structure 12. In this way, through the above structural arrangement, while ensuring a firmer connection between the power supply body 200 and the atomizer 100, it is convenient for any disassembly, installation and replacement between the power supply body 200 and the atomizer 100.

[0046] In some examples, as Figures 1 to 3 shown, the power supply module 210 includes a power supply component 211 and a second electrode component 212. The second electrode component 212 is electrically connected to the power supply component 211 and are respectively installed in the receiving chamber 222. The second electrode component 212 also partially protrudes from the bottom wall of the plug-in slot 221 to be electrically connected to the first electrode assembly when the second end of the inner shell 111 is inserted into the plug-in slot 221. In this way, through the above structural arrangement, the power supply component 211 disposed in the receiving chamber 222 can be better electrically connected to the first electrode assembly through the second electrode component 212.

[0047] The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structural transformation made under the inventive concept of the present application by using the content of the specification and drawings of the present application, or directly / indirectly applied to other related technical fields, is included in the patent protection scope of the present application.
