Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0057] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0058] The embodiments of this application provide an atomizer, which relates to the field of electronic atomization technology. It relates to the installation or removal between the atomizer 100 and the power supply device 200, which improves the convenience of replacing and recycling the atomizer 100. At the same time, the atomizer 100 has a good sealing effect and is not prone to leakage.

[0059] Combination Figures 1 to 4 As shown, the atomizer provided in this embodiment is used in combination with the atomizer 100 and the power supply device 200. The power supply device 200 is used to provide the working voltage to the atomizer 100 to ensure the stability and smoothness of the atomizer 100 during operation.

[0060] The atomizer 100 includes a housing 110 that defines a receiving cavity 115, in which an atomizing assembly 120 is disposed. The receiving cavity 115 may be configured as a separate cavity within the housing 110 or may be defined by the inner wall of the housing 110.

[0061] The outer shell 110 has a suction nozzle 111 at one end and a sealed bottom wall 112 at the other end. By setting the end of the outer shell 110 away from the suction nozzle 111 as a sealed bottom wall 112, it is possible to prevent droplets in the atomizing component 120 from leaking out of the outer shell 110, thereby ensuring the cleanliness of the surface of the outer shell 110.

[0062] In related technologies, the bottom wall 112 of the atomizer 100 often needs to be equipped with an air inlet, a liquid filling port, and contact electrodes, all of which are prone to leakage. In this embodiment, the bottom wall 112 does not have an air inlet or a liquid filling port, and the bottom wall 112 has no openings, thus eliminating the possibility of liquid droplets leaking from the bottom wall 112.

[0063] In one embodiment, the side wall 113 of the outer casing 110 is provided with a first connecting portion 114, which is used to connect to the power supply device 200, that is, the atomizer 100 can be connected to the power supply device 200 through the first connecting portion 114. Since the first connecting portion 114 is provided on the side wall 113 of the outer casing 110, it is connected to the power supply device 200 through the first connecting portion 114 provided on the side wall 113 of the atomizer 100. That is, the first connecting portion 114 is equivalent to the electrical connection interface and the airflow communication interface of the atomizer 100, and is used to form an electrical connection and an airflow communication with the power supply device 200 at this interface, respectively. Since the liquid atomizing matrix is ​​prone to leakage downward under the action of gravity when the device is stationary, that is, leakage from the bottom wall 112, this embodiment solves this problem by providing a sealed bottom wall 112. At the same time, the lateral leakage of the atomizing matrix is ​​less affected by the action of gravity.

[0064] In one exemplary implementation, reference is made to... Figure 1 The first connecting part 114 is located on the side wall 113 in the width direction of the atomizer 100.

[0065] In one exemplary embodiment (not shown in the figure), the first connection portion 114 is located on the sidewall in the thickness direction of the atomizer 100, i.e. Figure 2 The sidewall of the outer casing is shown (not labeled in the image).

[0066] In one embodiment, the connection between the first connecting part 114 and the power supply device 200 includes any one or a combination of two or more of the following: snap-fit, adhesive, magnetic connection, threaded connection, bolt connection, and interference fit connection. It is understood that by making the first connecting part 114 and the power supply device 200 detachably connected, not only can the stability of the connection between the atomizer 100 and the power supply device 200 be ensured, but the efficiency and convenience of installation or disassembly between the atomizer 100 and the power supply device 200 can also be improved, facilitating maintenance, replacement, or recycling.

[0067] Since the atomizer 100 needs to communicate with the power supply device 200 through airflow, that is, when the two are regarded as a whole device, the air intake part of the device is located in the power supply device 200, and the air outlet part of the device is located in the mouthpiece 111 of the atomizer. Therefore, the first connection part 114 of the atomizer 100 and the power supply device 200 need to have a certain airtightness at the airflow communication position. An interference fit connection method can be selected at the airflow communication position, for example, providing a sealing silicone ring, or the mutually mating parts are made of silicone material.

[0068] The receiving cavity 115 is defined inside the housing 110, and the suction nozzle 111 communicates with the receiving cavity 115 so that the gas in the receiving cavity 115 can be discharged through the suction nozzle 111.

[0069] The atomizing component 120 is disposed in the receiving cavity 115 and is connected to the inner wall of the outer shell 110 to ensure the stability of the atomizing component 120 in the receiving cavity 115. It should be noted that during operation, the atomizing component 120 can heat the atomizing matrix to form an aerosol, which can be discharged from the mouthpiece 111.

[0070] In this embodiment, the atomizing component 120 includes a first electrode connection structure 121, at least a portion of which is disposed in the first connection portion 114. This first electrode connection structure 121 is used for electrical connection with the power supply device 200. That is, when the atomizer 100 is connected to the power supply device 200 via the first connection portion 114, the portion of the first electrode connection structure 121 disposed in the first connection portion 114 forms an electrical connection with the power supply device 200, thereby electrically connecting the atomizing component 120 to the power supply device 200, so that the power supply device 200 provides operating voltage to the atomizing component 120, i.e., provides operating voltage to the atomizer 100.

[0071] In one embodiment, the first connecting portion 114 is disposed on the side wall 113 of the housing. The atomizer 100 can be connected to the power supply device 200 through the first connecting portion 114 to ensure the stability of the connection between the atomizer 100 and the power supply device 200. By disposing at least a portion of the first electrode connecting structure 121 in the first connecting portion 114, the first connecting portion 114 and the power supply device 200 are connected to ensure the stability of the connection between the atomizer 100 and the power supply device 200. At the same time, the first electrode connecting structure 121 and the power supply device 200 can form an electrical connection. This not only improves the stability and efficiency of the connection between the atomizer 100 and the power supply device 200, but also improves the efficiency and convenience of installation, disassembly, maintenance or recycling between the atomizer 100 and the power supply device 200.

[0072] like Figure 1 and Figure 4 As shown, in some embodiments, the first connecting portion 114 is disposed on the wider side wall 113 of the outer casing 110. It is understood that when the power supply device 200 is connected to the first connecting portion 114, the power supply device 200 is connected to the wider side wall 113 of the outer casing 110. That is, the power supply device 200 is connected to the wider side wall 113 of the atomizer 100. The larger the area of ​​connection or contact between the power supply device 200 and the atomizer 100, the higher the stability between them. This not only ensures the stability of the connection between the atomizer 100 and the power supply device 200, but also improves the space utilization between the atomizer 100 and the power supply device 200.

[0073] like Figure 1 and Figure 4As shown, in some embodiments, the first connection portion 114 is disposed on the side of the sidewall 113 near the bottom wall 112. Since the first electrode connection structure 121 is at least partially disposed in the first connection portion 114, it can be understood that by placing the first connection portion 114 on the side of the sidewall 113 away from the mouthpiece 111, not only can the electrical connection position between the atomizer 100 and the power supply device 200 be adjusted, but also the rationality and efficiency of the space utilization of the receiving cavity 115 can be controlled.

[0074] like Figure 4 As shown, in some embodiments, the housing 110 includes a first housing 116 and a first cover 117.

[0075] The first outer shell 116 and the first cover 117 are connected to form the receiving cavity 115. The connection method between the first outer shell 116 and the first cover 117 includes any one or a combination of two or more of the following: snap-fit, adhesive, magnetic connection, threaded connection, bolt connection, and interference fit connection.

[0076] In this embodiment, the first connecting portion 114 is disposed on the side wall 113 of the first cover 117. It is understood that the suction nozzle 111 is disposed at the end of the first outer shell 116 away from the first cover 117, and the first electrode connection structure 121 is at least partially disposed on the side wall 113 of the first cover 117.

[0077] like Figure 4 As shown, in some embodiments, the first connecting portion 114 includes an annular boss 1141, which is configured to provide positioning between the atomizer 100 and the power supply device 200. That is, when the atomizer 100 and the power supply device 200 are connected, the annular boss 1141 can be aligned and connected with the power supply device 200 to improve the accuracy, efficiency and stability of the installation between the atomizer 100 and the power supply device 200.

[0078] like Figure 3 and Figure 4 As shown, in some embodiments, the first connecting portion 114 further includes a through-hole 1142. It should be noted that the first guiding hole 1142 penetrates the first connecting portion 114, and the first guiding hole 1142 is configured to allow airflow to connect the receiving cavity 115 and the external air pressure, so as to connect the external space of the outer shell 110 with the receiving cavity 115 through the first guiding hole 1142, so that external gas can enter the receiving cavity 115 through the first guiding hole 1142 and be discharged through the suction nozzle 111.

[0079] like Figure 4As shown, in some embodiments, the inner ring of the annular boss 1141 is configured as a through-hole 1142. The first guide hole 1142 is configured to connect the airflow to the receiving cavity 115 and the external air pressure. That is, while the annular boss 1141 forms a limiting connection between the atomizer 100 and the power supply device 200, the first guide hole 1142 in the inner ring is used to connect the external space with the receiving cavity 115. The first guide hole 1142 connects the internal space of the power supply device 200 with the receiving cavity 115, so that the gas entering the power supply device 200 can enter the receiving cavity 115 through the first guide hole 1142 and be discharged through the mouthpiece 111.

[0080] like Figure 4 As shown, in some embodiments, the atomizer 100 includes a first housing 130, which is housed in a receiving cavity 115 and defines an installation space. The atomizing component 120 is disposed in the installation space so that the first housing 130 provides protection and fixation for the atomizing component 120, thereby ensuring the stability of the atomizing component 120 inside the first housing 130.

[0081] In this design, a guide groove 131 is recessed on one side of the first housing 130. One end of the guide groove 131 communicates with the atomizing channel 122 in the atomizing assembly 120, and the other end of the guide groove 131 communicates with the first guide hole 1142. This allows external gas to enter the guide groove 131 through the first guide hole 1142, flow through the guide groove 131, enter the atomizing channel 122, and be discharged through the mouthpiece 111. It is understood that one end of the atomizing channel 122 communicates with the guide groove 131, and the other end of the atomizing channel 122 communicates with the mouthpiece 111.

[0082] It should be noted that the shape of the guide channel 131 can be any one or a combination of two or more of the following: straight line, broken line, curved line, arc, ring, and letter shape, and can be specifically set according to the actual situation.

[0083] like Figure 3 and Figure 4 As shown, in some embodiments, the first electrode connection structure 121 includes a first pin 1211 and a second pin 1212. The first pin 1211 and the second pin 1212 are respectively used to connect to the power supply device 200, thereby electrically connecting the atomizer 100 and the power supply device 200.

[0084] The first housing 130 has a first mounting hole 132 and a second mounting hole 133 spaced apart on the side facing the first connecting portion 114. At least one end of the first pin 1211 is partially received in the first mounting hole 132, so that the hole wall of the first mounting hole 132 provides a limiting and positioning function for the first pin 1211, ensuring the stability of the first pin 1211 in the first mounting hole 132, and accurately positioning a portion of the first pin 1211 on the first connecting portion 114. Simultaneously, at least one end of the second pin 1212 is partially received in the second mounting hole 133, so that the hole wall of the second mounting hole 133 provides a limiting and positioning function for the second pin 1212, ensuring the stability of the second pin 1212 in the second mounting hole 133, and accurately positioning a portion of the second pin 1212 on the second connecting portion 241.

[0085] It should be noted that the first mounting hole 132 and the second mounting hole 133 are spaced apart on the first housing 130, thereby separating the first pin 1211 and the second pin 1212 to prevent short circuits from occurring when the first pin 1211 and the second pin 1212 come into contact, so as to ensure the stability and safety of the electrical connection between the atomizer 100 and the power supply device 200.

[0086] In this embodiment, the first pin 1211 is used to electrically connect to the first terminal 211 in the power supply device 200, and the second pin 1212 is used to electrically connect to the second terminal 212 in the power supply device 200, thereby forming an electrical connection between the atomizer 100 and the power supply device 200. This not only improves the stability of the connection between the atomizer 100 and the power supply device 200, but also ensures the accuracy and efficiency of the connection between the atomizer 100 and the power supply device 200.

[0087] like Figure 3 As shown, in some embodiments, the first cover 117 is provided with a limiting member 300 on the side facing the annular boss 1141. The limiting member 300 is sleeved on the second pole post 212 to provide a limiting and fixing effect on the second pole post 212 through the first limiting member 300, so as to ensure the accuracy and stability of the connection between the second pole post 212 and the second pin 1212.

[0088] The first cover 117 has a first clearance channel 1171 and a second clearance channel 1172 on the side facing the power supply device 200, and the first clearance channel 1171 and the second clearance channel 1172 are arranged at intervals.

[0089] In this embodiment, one end of the first clearance channel 1171 is connected to the guide groove 131, and the other end of the first clearance channel 1171 is connected to the first mounting hole 132. A portion of the first pin 1211 is housed in the first clearance channel 1171 to provide clearance and guidance for the first pin 1211, thereby achieving hidden routing of the first pin 1211. This not only ensures the neatness of the routing of the first pin 1211 in the receiving cavity 115, but also provides a limiting effect on the first pin 1211 through the inner wall of the first clearance channel 1171 to ensure the stability of the first pin 1211 in the receiving cavity 115.

[0090] In addition, one end of the second clearance channel 1172 is connected to the guide groove 131, and the other end of the second clearance channel 1172 is connected to the second mounting hole 133. A portion of the second pin 1212 is accommodated in the second clearance channel 1172 to provide clearance and guidance for the second pin 1212, thereby achieving hidden routing of the second pin 1212. This not only ensures the neatness of the routing of the second pin 1212 in the receiving cavity 115, but also provides a limiting effect on the second pin 1212 through the inner wall of the second clearance channel 1172 to ensure the stability of the second pin 1212 in the receiving cavity 115.

[0091] like Figures 5 to 8 As shown, this application provides a power supply device 200 for supplying power to the atomizer 100 described in any of the above embodiments, so as to ensure the stability and safety of the atomizer 100 during operation.

[0092] The power supply device 200 includes a second outer shell 230 and a second cover 240, which are connected to form a first cavity 250. A second connecting portion 241 is provided on the side wall 113 of the second cover 240. The second connecting portion 241 is connected to the first connecting portion 114 in the atomizer 100, thereby connecting the atomizer 100 and the power supply device 200. The connection method between the first connecting portion 114 and the second connecting portion 241 includes any one or a combination of two or more of the following: snap-fit, adhesive, magnetic connection, threaded connection, bolted connection, and interference fit connection.

[0093] In addition, the power supply device 200 includes a second electrode connection structure 210, which is housed in the first cavity 250. The second outer shell 230 and the second cover 240 provide limiting and protection for the second electrode connection structure 210 to ensure the stability of the second electrode connection structure 210 in the first cavity 250.

[0094] In this embodiment, the second electrode connection structure 210 is at least partially inserted through the side wall 113 of the second cover 240, and this part of the second electrode connection structure 210 inserted through the second cover 240 is electrically connected to the first electrode connection structure 121 in the atomizer 100, thereby electrically connecting the atomizer 100 and the power supply device 200.

[0095] like Figure 9 As shown, in some embodiments, the power supply device 200 and the atomizer 100 are detachably electrically connected.

[0096] The connection method between the power supply device 200 and the atomizer 100 includes at least one of the following: snap-fit, adhesive, magnetic connection, threaded connection, bolt connection, and interference fit connection, which can be specifically set according to the actual situation.

[0097] By detachably connecting the power supply device 200 and the atomizer 100, not only can the stability of the connection between the power supply device 200 and the atomizer 100 be guaranteed, but also the installation or disassembly efficiency between the power supply device 200 and the atomizer 100 can be improved, and the convenience of maintenance, replacement and recycling of the power supply device 200 and the atomizer 100 can be enhanced.

[0098] like Figure 5 and Figure 6 As shown, in some embodiments, the second cover 240 includes a side cover 242 and a bottom cover 243, which are connected to form the second cover 240. The second connecting portion 241 is disposed on the side cover 242. It should be noted that the side cover 242 corresponds to the side wall 113 described in any of the above embodiments. That is, when the first connecting portion 114 and the second connecting portion 241 are connected, the side cover 242 is directly opposite the side wall 113 to ensure the compactness of the connection between the atomizer 100 and the power supply device 200 and improve space utilization.

[0099] The side cover 242 has a recessed first groove 244 on the side opposite to the first cavity 250, and a first boss 245 protruding on the side of the side cover 242 facing the first cavity 250. The edge of the first boss 245 has a first opening 2451. It can be understood that the first opening 2451 connects the first groove 244 and the first cavity 250.

[0100] In addition, flanges 2452 are provided at intervals on the outer periphery of the first boss 245. The two ends of the flanges 2452 are located at the two ends of the first boss 245, and the two ends of the flanges 2452 are connected to the bottom cover 243. The first flow channel 248 is defined by the inner wall of the flanges 2452, the side of the side cover 242 facing the first cavity 250, and the side of the bottom cover 243 facing the first cavity 250. The first flow channel 248 is connected to the first groove 244 through the first opening 2451, that is, the gas in the first flow channel 248 can enter the first groove 244 through the first opening 2451.

[0101] It should be noted that the bottom cover 243 is provided with a first through hole 2431, which penetrates the bottom cover 243 along the thickness direction of the bottom cover 243 and is connected to the first guide channel 248, so that external gas can enter the first guide channel 248 through the first through hole 2431, and the gas flowing through the first guide channel 248 can enter the first groove 244 through the first opening 2451.

[0102] like Figure 7 and Figure 8 As shown, in some embodiments, a second boss 246 is provided on the side of the first boss 245 opposite to the side cover 242, and the second boss 246 and the flange 2452 are spaced apart to form a second annular channel 247. It can be understood that the second annular channel 247 is connected to the first guide channel 248.

[0103] The second annular channel 247 is provided with a first sealing element 220, which has a second through hole 221. The second through hole 221 penetrates the first sealing element 220 and connects to a first opening 2451, that is, the second through hole 221 connects to the first guide channel 248 through the first opening 2451. It can be understood that when external gas enters the first guide channel 248 through the first through hole 2431, a pressure difference can be formed between the second through hole 221 and the first guide channel 248.

[0104] like Figure 7 and Figure 8 As shown, in some embodiments, the power supply device 200 includes a battery cell 260, a control board 270, and an airflow sensor 280. The battery cell 260 and the control board 270 are respectively housed in the first cavity 250. The control board 270 is electrically connected to the battery cell 260 to provide power to the control board 270 through the battery cell 260.

[0105] The control board 270 is connected to the side cover 242. The control board 270 is provided with a third through hole 271 that communicates with the second through hole 221. The airflow sensor 280 is housed in the first cavity 250. The airflow sensor 280 is configured to generate a start signal in response to a change in negative pressure in the first cavity 250.

[0106] In this embodiment, the airflow sensor 280 is electrically connected to the control board 270. The control board 270 is configured to receive the start signal from the airflow sensor 280 and instruct the battery cell 260 to provide operating voltage to the atomizer 100 according to the start signal.

[0107] It is understandable that when external gas enters the first flow channel 248 through the first through hole 2431, a pressure difference is formed between the third through hole 271 and the first flow channel 248 because the second through hole 221 and the third through hole 271 are connected. The airflow sensor 280 can detect this pressure difference and send an electrical signal to the control board 270 to make the atomizing component 120 and the power supply conduct current, thereby activating the atomizing component 120. This not only improves the trigger sensitivity of the atomizing device, but also effectively improves the smoothness of airflow and ensures the consistency of taste.

[0108] By connecting the airflow sensor 280 to the power supply component and connecting the airflow sensor 280 to the first flow channel 248 provided in the power supply component, the airflow sensor 280 can quickly detect the air pressure change in the first flow channel 248, thereby shortening the time for the airflow sensor 280 to sense the user's suction action, thus improving the sensitivity of the airflow sensor 280 and also improving the smoothness of the airflow.

[0109] The advantage of integrating the airflow sensor 280 into the power supply unit 200 is that even under extreme conditions, if the atomizer 100 leaks, the leaked liquid will not infiltrate the airflow sensor 280. Furthermore, the atomizer 100 and the power supply unit 200 are often stored separately during transport, which makes the possibility of the airflow sensor 280 failing extremely low.

[0110] In one embodiment, the airflow sensor 280 may also be integrated into the atomizer 100, for example, located in the receiving cavity 115 near the mouthpiece 111, and a contact point (not shown) for communication between the airflow sensor 280 and the power supply device 200 is provided on the first connection portion 114.
