[0003] However, in some regions, due to safety, compliance and other considerations, it is required that the liquid storage tank and the atomizing component be packaged separately and have a liquid storage tank with a rated volume. This requires providing users with a convenient assembly structure and compliant atomizing matrix storage space. Utility Model Content

[0004] The main purpose of this invention is to provide an atomizer and electronic atomizing device that can package the liquid storage tank and atomizing components separately, so that users can use them conveniently and safely.

[0005] To achieve the above objectives, this application provides an atomizer having a reservoir for storing an atomizing matrix. The atomizer includes:

[0006] The nozzle has an air inlet end and an air outlet end, as well as a first wall and a second wall extending between the air inlet end and the air outlet end. The first wall and the second wall define a first cavity on the side near the air inlet end, and the second wall encloses a gas channel that penetrates the first cavity.

[0037] Electronic atomizing devices can be used in various fields, such as medical atomization, beauty atomization, and cigarette alternatives. They primarily utilize a heated atomizing matrix to generate an aerosol, which can be a liquid matrix containing or without nicotine. Electronic atomizing devices generally include an atomizing component and a power supply component. The atomizing component includes an e-liquid reservoir that stores the atomizing matrix and an atomizing coil. The e-liquid reservoir stores the atomizing matrix, and the atomizing coil heats and atomizes the matrix to generate an aerosol. The power supply component provides power to the atomizing coil.

[0038] This application provides an atomizer, such as Figures 1-8 As shown, the atomizer has a detachably connected mouthpiece 10 and atomizing component 20. After the mouthpiece 10 and atomizing component 20 are connected, they together form a liquid storage chamber. Distributors can package the mouthpiece 10 and atomizing component 20 separately. After receiving the mouthpiece 10 and atomizing component 20, the user can connect the mouthpiece 10 and atomizing component 20 and inject the atomizing matrix into the liquid storage chamber. The atomizing component 20 obtains the atomizing matrix from the liquid storage chamber and can heat the atomizing matrix to form an aerosol under the user's operation of the atomizer.

[0039] See Figure 3 The nozzle 10 has an air inlet end 102 and an air outlet end 101, as well as a first wall 103 and a second wall 104 extending between the air inlet end 102 and the air outlet end 101. The first wall 103 and the second wall 104 define a first cavity 105 on the side near the air inlet end 102. The second wall 104 encloses a gas channel 106, which passes through the first cavity 105, and the two ends of the gas channel 106 are respectively connected to the air inlet end 102 and the air outlet end 101.

[0040] See Figures 4A to 4C A mouthpiece 10 housing 201 with a mouth-holding portion is formed around the outer periphery of the first wall 103 surrounding the second wall 104. The side of the first wall 103 facing away from the second wall 104 is constructed as the surface of the mouthpiece 10. The side of the first wall 103 close to the second wall 104 is spaced apart from the second wall 104, and the gap between the two is configured as a first cavity 105.

[0041] Furthermore, a notch 109 is provided on the first wall 103, and the notch 109 communicates with the first cavity 105. (See also...) Figure 4A and Figure 4C The notch 109 gives the first cavity 105 a volume of less than or equal to 2 ml.

[0042] To enable the reuse of the liquid storage chamber, an injection port 107 is provided on the first wall 103, and the injection port 107 is sealed with a sealing plug 108. In some embodiments, the sealing plug 108 is puncturable; for example, the sealing plug 108 can be punctured by an injection tube to inject the atomized matrix into the liquid storage chamber. It is understood that the sealing plug 108 may be made of self-sealing or self-recovering silicone or rubber, so that the punctured sealing plug 108 can close itself after the injection tube is removed. In some embodiments, the sealing plug 108 is removable and is inserted into the injection port 107. In addition, the sealing plug 108 has a plug head and a plug tail. The plug head is used to insert into the injection port 107 for the user to open or close the injection port 107, and the plug tail is fixed to the first wall 103 so that the plug head is suspended after being pulled out, preventing the sealing plug 108 from being lost after being pulled out.

[0043] The first wall 103 serves as the surface structure of the nozzle 10 and can be connected to the atomizing assembly 20. The first wall 103 is provided with a locking portion, which can engage with the atomizing assembly 20. The locking portion can be a slot 1010 or a protrusion 207. In some embodiments, such as... Figure 4B As shown, the engaging part can be a slot 1010 provided on the first wall 103.

[0044] The second wall 104 forms a gas channel 106, and the outer wall of the gas channel 106 is spaced apart from the first wall 103, forming a first cavity 105. Figure 4C As shown, the second wall 104 and the first wall 103 are connected on the side near the air outlet 101 of the nozzle 10 to form a closed end. The second wall 104 and the first wall 103 are spaced apart on the side near the air inlet 102 of the nozzle 10, forming a first cavity 105. A gas channel 106 passes through the first cavity 105, and the two ends of the gas channel 106 are respectively connected to the air inlet 102 and the air outlet 101 of the nozzle 10. It can be understood that the second wall 104 and the first wall 103 can be integrally formed, and the two are connected at one end on the same side to form the closed end of the first cavity 105. The gas channel 106 can be understood to pass through the first wall 103 to form an air outlet 101 for aerosol discharge on the first wall 103; the other end of both is open, used to connect with the atomizing component 20, and to close the first cavity 105, and to connect the gas channel 106 with the air passage on the atomizing component 20 for aerosol passage.

[0045] The gas channel 106 constructed by the second wall 104 has an axially extending length, which is approximately equal to the length from the closed end of the first cavity 105 to the notch 109. For example... Figure 4C As shown, the air inlet end 102 of the gas channel 106 is hidden within the first cavity 105 and protected by the outer shell formed by the first wall 103. This prevents the nozzle 10 from damaging the gas channel 106 during independent transportation or storage, and further prevents the gas channel 106 from communicating with the liquid storage chamber after the nozzle 10 is connected to the atomizing assembly 20, thus preventing the atomizing matrix from leaking into the gas channel 106.

[0046] The atomizing assembly 20 includes a housing 201, an atomizing core 205, and an atomizing tube 202. The housing 201 has an internal mounting cavity for mounting the atomizing tube 202. The housing 201 is used to connect with the mouthpiece 10 so that the first cavity 105 is closed to form a liquid storage cavity. The atomizing tube 202 is installed in the mounting cavity and has a first liquid inlet 2021 that communicates with the liquid storage cavity. The atomizing core 205 is fixed inside the atomizing tube 202. The atomizing core 205 absorbs and heats the atomizing matrix through the first liquid inlet 2021 to convert the atomizing matrix into an aerosol.

[0047] The housing 201 has a connecting surface for connecting to the suction nozzle 10, and the connecting surface is provided with a detachable engaging structure for the suction nozzle 10. The engaging structure can be a groove 1010 or a protrusion 207 that engages with the engaging portion on the first wall 103 in the above embodiment. For example... Figure 2 As shown, the engaging structure on the housing 201 that is detachably connected to the nozzle 10 is a latching protrusion 207, which engages with the latching groove 1010 on the first wall 103 of the above embodiment.

[0048] The housing 201 has a top and a bottom, and a sidewall connecting the top and bottom of the housing 201. The top, bottom, and sidewall together form a cavity, and the atomizing tube 202 is at least partially disposed within the cavity. It is understood that the sidewall of the housing 201 has an inner diameter that matches the inner diameter of the first cavity 105, that is, at least part of the sidewall of the housing 201 can be interference-fitted or adapted to the first wall 103.

[0049] In some embodiments, the top or bottom of the housing 201 is detachable, allowing the user to replace the atomizing tube 202 or the atomizing core 205 by removing the top or bottom. Specifically, the top of the housing 201 is provided with a sealing cap 206, which, together with the housing 201, defines a cavity formed inside the housing 201. The atomizing tube 202 is installed in the cavity, and the outer wall of the atomizing tube 202 is spaced apart from the inner wall of the housing 201 to form a second cavity 203. The second cavity 203 communicates with the first cavity 105 to form a liquid storage chamber. Figure 2 As shown, the sealing cap 206 is provided with multiple fluid passages, at least one of which serves as a liquid passage 2061 for allowing the atomizing matrix to flow from the first cavity 105 into the second cavity 203. At least one fluid passage also serves as an insertion interface 208 for connecting to the second wall 104 to connect the atomizing tube 202 to the gas channel 106.

[0050] In some embodiments, the volume of the second cavity 203 is less than 2 ml. Or, the volume of the liquid storage cavity formed after the second cavity 203 communicates with the first cavity 105 is less than or equal to 2 ml.

[0051] In some embodiments, a liquid storage cotton 209 is provided in the second cavity 203, and the liquid storage cotton 209 wraps around the atomizing tube 202. It is understood that the liquid storage cotton 209 absorbs the atomizing matrix injected by the user into the liquid storage cavity, and slowly releases it into the atomizing tube 202 through the liquid inlet via capillary action.

[0052] In some embodiments, to increase the sealing between the nozzle 10 and the atomizing component 20, the sealing cap 206 is made of silicone or rubber. The sealing cap 206 is placed on the housing 201 and is clamped between the outer wall of the housing 201 and the inner wall of the first cavity 105 to achieve the sealing of the liquid storage cavity.

[0053] In some embodiments, the bottom of the housing 201 has a detachable base 212, the base 212 is provided with an air inlet 211, and one end of the atomizing tube 202 is fixed on the base 212 and communicates with the air inlet 211.

[0054] like Figure 3 or Figure 6 As shown, the atomizing tube 202 has a hollow tube structure. One end of the tube is connected to the fluid passage on the sealing cap 206, and the other end is connected to the air inlet on the base 212. After the nozzle 10 is connected to the housing 201, the atomizing tube 202 communicates with the gas channel 106. Figure 6 As indicated by the middle arrow, external air enters the air passage 204 through the air inlet 211, then mixes with the aerosol, and is discharged from the outlet 101 of the nozzle 10 through the gas passage 106 connected to the air passage 204.

[0055] The atomizer core 205 includes a heating element and a support 210. For example... Figures 6 to 7 As shown, the support 210 is a tube structure. The support 210 is installed inside the atomizing tube 202. An air flow channel is defined inside the support 210. The air flow channel is connected to the gas channel 106. A liquid storage space is formed between the support 210 and the atomizing tube 202. The heating element is installed in the air flow channel. The support 210 is provided with a second liquid inlet 2100. The atomizing matrix supplies liquid to the heating element through the second liquid inlet 2100.

[0056] In some embodiments, a liquid storage cotton 209 is provided in the liquid storage space. One side of the liquid storage cotton 209 is attached to the bracket 210 to supply liquid to the heating element, and the other side of the liquid storage cotton 209 is attached to the inner wall of the atomizing tube 202. The liquid storage cotton 209 absorbs the atomizing matrix in the second cavity 203 through the liquid inlet hole.

[0057] This application also provides an electronic atomizing device having the atomizer of any of the above embodiments.

[0058] In some embodiments, the above-described electronic atomizing device further includes a power supply component 30, which is detachably connected to the atomizer. For example... Figure 9 As shown, the power supply assembly 30 has a housing 201, inside which a battery is housed. After the housing 201 is connected to the atomizer, the battery is electrically connected to the heating element in the atomizer. Specifically, the housing 201 of the power supply assembly 30 forms a receiving cavity 31 on one side, and the atomizer is at least partially housed within the receiving cavity 31. In some embodiments, the portion of the atomizer exposed outside the receiving cavity 31 is a transparent area, through which the user can observe the consumption of the atomizing matrix within the atomizer.

[0059] The above description is only a part or preferred embodiment of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
