Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0028] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] The embodiment of the present application provides an atomizer, which relates to the field of electronic atomization technology, and involves installation or disassembly between an atomizer 100 and a power supply device 200, thereby improving the convenience of replacement and recycling of the atomizer 100. At the same time, the atomizer 100 has a good sealing effect and is not prone to leakage.

[0030] Combination Figures 1 to 4 As shown, in the atomizer provided in this embodiment, the atomizer 100 and the power supply device 200 are used in combination, and the power supply device 200 is used to provide a working voltage to the atomizer 100 to ensure the stability and smoothness of the atomizer 100 during operation.

[0031] The atomizer 100 includes a housing 110, which defines a housing chamber 115, and the atomizer assembly 120 is disposed in the housing chamber 115. The housing chamber 115 may be constructed as an independent cavity in the housing 110, or may be defined by the inner wall of the housing 110.

[0032] A suction nozzle 111 is provided at one end of the shell 110, and the other end of the shell 110 is a sealed bottom wall 112. By setting the end of the shell 110 away from the suction nozzle 111 as the sealed bottom wall 112, droplets in the atomization assembly 120 can be prevented from leaking out of the shell 110, thereby ensuring the cleanliness of the surface of the shell 110.

[0033] In the related art, the bottom wall 112 of the atomizer 100 often needs to be provided with an air inlet, a liquid injection port, a contact electrode, etc., wherein the above positions are prone to leakage. In this embodiment, the bottom wall 112 is not provided with an air inlet and a liquid injection port, and the bottom wall 112 has no opening, thereby eliminating the possibility of liquid droplets leaking from the bottom wall 112.

[0034] In one embodiment, the side wall 113 of the housing 110 is provided with a first connection portion 114, and the first connection portion 114 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 connection portion 114. Since the first connection portion 114 is arranged on the side wall 113 of the housing 110, it is connected to the power supply device 200 through the first connection portion 114 arranged on the side wall 113 of the atomizer 100. That is, the first connection 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 airflow communication with the power supply device 200 at this interface respectively. Since the device is in a stationary state, the liquid atomized matrix is ​​easily leaked downward by gravity, that is, leaking from the bottom wall 112. According to the above, this embodiment solves this problem by providing a sealed bottom wall 112. At the same time, the lateral leakage of the atomized matrix is ​​less affected by gravity.

[0035] In an exemplary embodiment, referring to Figure 1The first connection portion 114 is located on the side wall 113 of the atomizer 100 in the width direction.

[0036] In an exemplary embodiment (not shown), the first connecting portion 114 is located on the side wall of the atomizer 100 in the thickness direction, that is, Figure 2 The side wall of the housing is shown (not labeled in the figure).

[0037] In one embodiment, the connection between the first connection portion 114 and the power supply device 200 includes any one of snap connection, bonding, magnetic connection, threaded connection, bolt connection, and interference fit connection, or a combination of two or more thereof. It is understandable that by making the first connection portion 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 also the efficiency and convenience of installation or disassembly between the atomizer 100 and the power supply device 200 can be improved, so as to facilitate maintenance, replacement or recycling.

[0038] Since the atomizer 100 needs to be connected to the power supply device 200 for airflow, that is, when the two are viewed as a whole device, the air inlet part of the device is located in the power supply device 200, and the air outlet part of the device is located in the suction nozzle 111 of the atomizer. Therefore, the first connecting part 114 of the atomizer 100 and the power supply device 200 need to have a certain airtightness at the airflow connection position, and an interference fit connection method can be selected at the airflow connection position, for example, a sealing silicone ring is provided, or the parts that cooperate with each other are made of silicone material.

[0039] The accommodating chamber 115 is defined inside the housing 110 , and the suction nozzle 111 is in communication with the accommodating chamber 115 , so that the gas in the accommodating chamber 115 can be discharged through the suction nozzle 111 .

[0040] The atomizer assembly 120 is disposed in the accommodating cavity 115, and the atomizer assembly 120 is connected to the inner wall of the housing 110 to ensure the stability of the atomizer assembly 120 in the accommodating cavity 115. It should be noted that the atomizer assembly 120 can heat the atomized substrate to form an aerosol during operation, and the aerosol can be discharged from the nozzle 111.

[0041] In this embodiment, the atomizer assembly 120 includes a first electrode connection structure 121, at least a portion of which is disposed on the first connection portion 114, and the first electrode connection structure 121 is used to be electrically connected to 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, at this time, a portion of the first electrode connection structure 121 disposed on the first connection portion 114 can form an electrical connection with the power supply device 200, thereby electrically connecting the atomizer assembly 120 to the power supply device 200, so as to provide the atomizer assembly 120 with a working voltage through the power supply device 200, that is, to provide the atomizer 100 with a working voltage through the power supply device 200.

[0042] In one embodiment, the first connecting portion 114 is disposed on the side wall 113 of the shell, and 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 on 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, while the first electrode connecting structure 121 can be electrically connected to the power supply device 200, which can not only improve the stability and efficiency of the connection between the atomizer 100 and the power supply device 200, but also improve the efficiency and convenience of installation, disassembly, maintenance or recycling between the atomizer 100 and the power supply device 200.

[0043] like Figure 1 and Figure 4 As shown, in some embodiments, the first connection portion 114 is disposed on the wider side wall 113 of the housing 110. It is understandable that when the power supply device 200 is connected to the first connection portion 114, the power supply device 200 is connected to the wider side wall 113 of the housing 110, that is, the power supply device 200 is connected to the wider side wall 113 of the atomizer 100, that is, the larger the connection or contact area between the power supply device 200 and the atomizer 100, the higher the stability between the two, which can not only ensure the stability of the connection between the atomizer 100 and the power supply device 200, but also improve the space utilization between the atomizer 100 and the power supply device 200.

[0044] like Figure 1 and Figure 4As shown, in some embodiments, the first connection portion 114 is disposed on a side of the side wall 113 close to the bottom wall 112. Since the first electrode connection structure 121 is at least partially disposed on the first connection portion 114, it can be understood that by locating the first connection portion 114 on a side of the side wall 113 away from the mouthpiece 111, not only the electrical connection position between the atomizer 100 and the power supply device 200 can be adjusted, but also the rationality and efficiency of the space utilization of the accommodating cavity 115 can be controlled.

[0045] like Figure 4 As shown, in some embodiments, the housing 110 includes a first housing 116 and a first cover 117 .

[0046] Among them, the first shell 116 and the first cover body 117 are connected to form the accommodating cavity 115, and the connection method between the first shell 116 and the first cover body 117 includes any one of snap connection, bonding, magnetic connection, threaded connection, bolt connection, interference fit connection, or a combination of two or more.

[0047] In this embodiment, the first connection portion 114 is disposed on the side wall 113 of the first cover 117. It is understandable that the nozzle 111 is disposed at one end of the first housing 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.

[0048] like Figure 4 As shown, in some embodiments, the first connecting portion 114 includes an annular boss 1141, and the annular boss 1141 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 to the power supply device 200 to improve the installation accuracy, installation efficiency and connection stability between the atomizer 100 and the power supply device 200.

[0049] like Figure 3 and Figure 4 As shown, in some embodiments, the first connection portion 114 also includes a first guide hole 1142 that is arranged therethrough. It should be noted that the first guide hole 1142 passes through the first connection portion 114, and the first guide hole 1142 is configured to connect the airflow to the accommodating cavity 115 and the external air pressure, so as to connect the external space of the housing 110 with the accommodating cavity 115 through the first guide hole 1142, so that the external gas can enter the accommodating cavity 115 through the first guide hole 1142 and be discharged through the suction nozzle 111.

[0050] like Figure 4As shown, in some embodiments, the inner ring of the annular boss 1141 is configured as a first flow guide hole 1142 that is arranged through it, and the first flow guide hole 1142 is configured to connect the airflow to the accommodating chamber 115 and the external air pressure, that is, while a limiting connection is formed between the atomizer 100 and the power supply device 200 through the annular boss 1141, the first flow guide hole 1142 arranged on the inner ring is used to connect the external space with the accommodating chamber 115, so that the internal space of the power supply device 200 is connected with the accommodating chamber 115 through the first flow guide hole 1142, so that the gas entering the power supply device 200 can enter the accommodating chamber 115 through the first flow guide hole 1142 and be discharged through the nozzle 111.

[0051] like Figure 4 As shown, in some embodiments, the atomizer 100 includes a first shell 130, which is received in the accommodating cavity 115 and defines an installation space. The atomizer assembly 120 is arranged in the installation space to protect and fix the atomizer assembly 120 through the first shell 130 to ensure the stability of the atomizer assembly 120 inside the first shell 130.

[0052] Among them, one side of the first shell 130 is recessed to form a guide groove 131, one end of the guide groove 131 is connected to the atomization channel 122 in the atomization assembly 120, and the other end of the guide groove 131 is connected to the first guide hole 1142, so that the external gas can enter the guide groove 131 through the first guide hole 1142, flow through the guide groove 131, enter the atomization channel 122, and be discharged through the suction nozzle 111. It can be understood that one end of the atomization channel 122 is connected to the guide groove 131, and the other end of the atomization channel 122 is connected to the suction nozzle 111.

[0053] It should be noted that the shape of the guide groove 131 can be any one of a straight line, a broken line, a curve, an arc, a ring, and a letter shape, or a combination of two or more thereof, and can be specifically set according to actual conditions.

[0054] 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, so as to electrically connect the atomizer 100 and the power supply device 200.

[0055] The first housing 130 is provided with a first mounting hole 132 and a second mounting hole 133 spaced apart from each other on one side facing the first connection portion 114. One end of the first pin 1211 is at least partially received in the first mounting hole 132, so that the first pin 1211 is provided with a limiting and positioning function through the hole wall of the first mounting hole 132, so as to ensure the stability of the first pin 1211 in the first mounting hole 132, and a part of the first pin 1211 is accurately positioned on the first connection portion 114. At the same time, one end of the second pin 1212 is at least partially received in the second mounting hole 133, so that the second pin 1212 is provided with a limiting and positioning function through the hole wall of the second mounting hole 133, so as to ensure the stability of the second pin 1212 in the second mounting hole 133, and a part of the second pin 1212 is accurately positioned on the second connection portion 241.

[0056] It should be noted that the first mounting hole 132 and the second mounting hole 133 are spaced apart on the first shell 130, so as to separate the first pin 1211 and the second pin 1212, so as to prevent the first pin 1211 and the second pin 1212 from short-circuiting due to contact, so as to ensure the stability and safety of the electrical connection between the atomizer 100 and the power supply device 200.

[0057] In this embodiment, the first pin 1211 is used to electrically connect to the first pole 211 in the power supply device 200, and the second pin 1212 is used to electrically connect to the second pole 212 in the power supply device 200, so as to form an electrical connection between the atomizer 100 and the power supply device 200, which can not only improve the stability of the connection between the atomizer 100 and the power supply device 200, but also ensure the accuracy and connection efficiency of the connection between the atomizer 100 and the power supply device 200.

[0058] like Figure 3 As shown, in some embodiments, a limiting member 300 is provided on one side of the first cover body 117 facing the annular boss 1141, and the limiting member 300 is sleeved on the second pole 212 to provide limiting and fixing functions for the second pole 212 through the first limiting member 300, so as to ensure the accuracy and stability of the connection between the second pole 212 and the second pin 1212.

[0060] In this embodiment, one end of the first give way channel 1171 is communicated with the guide groove 131, and the other end of the first give way channel 1171 is communicated with the first mounting hole 132. A portion of the first pin 1211 is accommodated in the first give way channel 1171, so as to provide the first pin 1211 with a give way and guide function through the first give way channel 1171, so as to realize the hidden routing of the first pin 1211, so as to not only ensure the neatness of the routing of the first pin 1211 in the accommodating cavity 115, but also provide a limiting function for the first pin 1211 through the inner wall of the first give way channel 1171, so as to ensure the stability of the first pin 1211 in the accommodating cavity 115.

[0063] The power supply device 200 includes a second housing 230 and a second cover 240, the second housing 230 and the second cover 240 are connected to form a first cavity 250, the side wall 113 of the second cover 240 is provided with a second connecting portion 241, the second connecting portion 241 is connected to the first connecting portion 114 in the atomizer 100, so as to connect 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 of snap connection, bonding, magnetic connection, threaded connection, bolt connection, and interference fit connection, or a combination of two or more thereof.

[0064] In addition, the power supply device 200 includes a second electrode connection structure 210, which is accommodated in the first cavity 250, so as to provide limiting and protection for the second electrode connection structure 210 through the second shell 230 and the second cover 240 to ensure the stability of the second electrode connection structure 210 in the first cavity 250.

[0065] In this embodiment, the second electrode connection structure 210 at least partially penetrates the side wall 113 of the second cover body 240, and the portion of the second electrode connection structure 210 that penetrates the second cover body 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.

[0066] like Fig. 9 As shown, in some embodiments, the power supply device 200 and the atomizer 100 are detachably electrically connected.

[0067] The connection method between the power supply device 200 and the atomizer 100 includes at least one of snap connection, bonding, magnetic connection, threaded connection, bolt connection, and interference fit connection, which can be specifically set according to actual conditions.

[0068] By making the power supply device 200 and the atomizer 100 detachably connected, not only can the stability of the connection between the power supply device 200 and the atomizer 100 be ensured, but also the installation or disassembly efficiency between the power supply device 200 and the atomizer 100 can be improved, and the convenience of repairing, replacing and recycling the power supply device 200 and the atomizer 100 can be improved.

[0069] like Figure 5 and Figure 6 As shown, in some embodiments, the second cover body 240 includes a side cover 242 and a bottom cover 243, the side cover 242 and the bottom cover 243 are connected to form the second cover body 240, and the second connecting portion 241 is arranged 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 opposite to the side wall 113, so as to ensure the compactness of the connection between the atomizer 100 and the power supply device 200 and improve the space utilization.

[0070] The side of the side cover 242 facing away from the first cavity 250 is provided with a depression to form a first groove 244, and the side of the side cover 242 facing the first cavity 250 is convex to form a first boss 245, and the edge of the first boss 245 is provided with a first opening 2451. It can be understood that the first opening 2451 connects the first groove 244 and the first cavity 250.

[0071] In addition, flanges 2452 are arranged at intervals on the outer periphery of the first boss 245, and two ends of the flange 2452 are respectively located at two ends of the first boss 245, and the two ends of the flange 2452 are respectively connected to the bottom cover 243, and a first guide channel 248 is defined by the inner wall of the flange 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, and the first guide channel 248 is connected to the first groove 244 through the first opening 2451, that is, the gas in the first guide channel 248 can enter the first groove 244 through the first opening 2451.

[0072] 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 the first through hole 2431 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.

[0073] 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 away from 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 communicated with the first guide channel 248.

[0074] The second annular channel 247 is provided with a first sealing member 220, and the first sealing member 220 is provided with a second through hole 221, the second through hole 221 penetrates the first sealing member 220, and the second through hole 221 is connected to the first opening 2451, that is, the second through hole 221 is connected 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.

[0075] 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 accommodated in the first cavity 250, and the control board 270 is electrically connected to the battery cell 260 to provide electrical energy to the control board 270 through the battery cell 260.

[0076] The control panel 270 is connected to the side cover 242 , and the control panel 270 is provided with a third through hole 271 connected to the second through hole 221 . The airflow sensor 280 is accommodated in the first cavity 250 , and the airflow sensor 280 is configured to generate a start signal in response to a change in negative pressure in the first cavity 250 .

[0077] In this embodiment, the airflow sensor 280 is electrically connected to the control board 270 , and the control board 270 is configured to receive a start signal from the airflow sensor 280 , and instruct the battery cell 260 to provide a working voltage to the atomizer 100 according to the start signal.

[0078] It can be understood that when external gas enters the first guide channel 248 through the first through hole 2431, since the second through hole 221 and the third through hole 271 are connected, an air pressure difference can be formed in the third through hole 271 and the first guide channel 248. The air pressure difference can be detected by the airflow sensor 280, and an electrical signal is sent to the control board 270 to enable the atomization component 120 to form current conduction with the power supply, thereby starting the atomization component 120. This can not only improve the triggering sensitivity of the atomization device, but also effectively improve the smoothness of the airflow circulation, thereby ensuring the consistency of taste.

[0079] By connecting the airflow sensor 280 and the power supply assembly, and connecting the airflow sensor 280 with the first guide channel 248 provided in the power supply assembly, the airflow sensor 280 can quickly detect the air pressure change in the first guide channel 248, so as to shorten the time for the airflow sensor 280 to sense the user's suction action, thereby improving the sensitivity of the airflow sensor 280 and also improving the smoothness of the airflow.

[0080] The advantage of integrating the airflow sensor 280 in the power supply device 200 is that, even if the atomizer 100 leaks under extreme conditions, the leaked liquid will not invade the airflow sensor 280. In addition, the atomizer 100 and the power supply device 200 are often stored separately during transportation, which makes the possibility of failure of the airflow sensor 280 extremely low.

[0081] In one embodiment, the airflow sensor 280 may also be integrated into the atomizer 100, for example, disposed in the accommodating chamber 115 near the nozzle 111, and a contact for communication between the airflow sensor 280 and the power supply device 200 is provided on the first connecting portion 114 (not shown).
