For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] The present invention provides a power supply component for an electronic cigarette, which is used to supply power to the atomizer of the electronic cigarette. The power supply component includes a main body with an internal circuit board and a housing covering the main body. An installation space is formed between the housing and the main body. A power source that can be cyclically charged or discharged is provided inside the power supply component, and a plug-in terminal component is provided for charging and data transmission. The plug-in terminal can be a micro-type charging female socket, a lightning-type charging female socket, or a Typec-type charging female socket, etc. The power supply component is used to supply power to an external load. In the embodiment of the present invention, taking the external load as an atomizer as an example, the power supply component and the atomizer form an electronic cigarette.

[0031] Referring to Figures 1 to 6 , the present invention provides a power supply component for an electronic cigarette. The power supply component 600 of the electronic cigarette includes: a housing 100, a connecting member 200, and a trigger switch 300. The housing 100 is provided with a receiving cavity 103, and the receiving cavity 103 is used to install an atomizer 500. The housing 100 is further provided with an induction air passage 105 outside the receiving cavity 103. The induction air passage 105 is communicated with the intake air passage of the atomizer 500. The trigger switch 300 is arranged in the induction air passage 105. The induction air passage 105 is spaced from the receiving cavity 103 to prevent leaked smoke liquid from entering the induction air passage 105.

[0032] Specifically, the receiving cavity 103 is the connecting part between the housing 100 and the atomizer 500. The atomizer 500 is fixedly connected to the housing 100 by connecting with the receiving cavity 103. The receiving cavity 103 has opposite ends, and the atomizer 500 is connected to the open end of the receiving cavity 103. Among them, the housing 100 can be the power supply component 600, that is, the housing 100 can be made of a conductive material, and the housing 100 can be used as the first electrode of the power supply component 600, that is, the housing 100 is used as the negative electrode of the power supply component 600 and is communicated with the atomizer 500. Since the induction air passage 105 is communicated with the intake air passage of the atomizer 500, when the user sucks smoke through the atomizer 500, the trigger switch 300 in the induction air passage 105 can be triggered to work, so as to achieve the effect of instant use and improve the working performance of the atomizer 500.

[0033] It should be noted that when the power supply component 600 of the electronic cigarette 1000 is connected to the atomizer 500 of the electronic cigarette 1000, under the negative pressure generated by the long-term placement and suction of the electronic cigarette 1000, the e-liquid will leak into the heating core of the electronic cigarette 1000, and the leaked e-liquid will flow along the atomization chamber 400 of the atomizer 500 into the accommodation chamber 103. Since the induction air passage 105 is arranged at an interval from the accommodation chamber 103, that is, the induction air passage 105 is located outside the accommodation chamber 103, the e-liquid leaked in the accommodation chamber 103 cannot enter the induction air passage 105, avoiding the trigger switch 300 being affected by the e-liquid, and further ensuring that the trigger switch 300 in the induction air passage 105 can work normally. The trigger switch 300 can be an air-triggered microphone head, which is used to sense the air pressure to control whether the atomizer 500 atomizes the e-liquid, so as to facilitate the control of the operation of the electronic cigarette 1000.

[0034] After adopting the above technical solution, by providing the accommodation chamber 103 on the housing 100, installing the atomizer 500 in the accommodation chamber 103 of the housing 100, and opening the induction air passage 105 outside the accommodation chamber 103, and arranging the trigger switch 300 in the induction air passage 105, since the induction air passage 105 and the accommodation chamber 103 are arranged at an interval, the e-liquid leaked from the atomizer 500 installed in the accommodation chamber 103 will not directly flow from the accommodation chamber 103 to the induction air passage 105, avoiding the phenomenon that the e-liquid leaked from the atomizer 500 flows to the trigger switch 300, thereby ensuring the normal use of the trigger switch 300.

[0035] Please continue to refer to Figure 2 , in an alternative embodiment, the housing 100 further has a first accommodation groove 102 at the opening end of the accommodation chamber 103, and the opening end of the first accommodation groove 102 is communicated with the induction air passage 105. In this embodiment, by opening the first accommodation groove 102 at the opening end of the housing 100, the first accommodation groove 102 is used to store the excess e-liquid leaked from the atomizer 500, further avoiding the e-liquid leaked from the atomizer 500 from entering the induction air passage 105. Among them, the opening directions of the first accommodation groove 102 and the accommodation chamber 103 are the same, that is, the opening directions of the first accommodation groove 102 and the accommodation chamber 103 are both set in the direction of the housing 100 facing the atomizer 500.

[0036] It should be noted that an oil drainage hole 401 is provided at the bottom of the atomization chamber 400 of the atomizer 500 at a position corresponding to the first accommodation groove 102, so that the first accommodation groove 102 is communicated with the atomization chamber 400 of the atomizer 500 through the oil drainage hole 401. The induction air passage 105 is communicated with the first accommodation groove 102, facilitating the communication between the induction air passage 105 and the air intake passage of the atomizer 500.

[0037] Please continue to refer to Figure 1 and Figure 2 In an alternative embodiment, both the induction air passage 105 and the first accommodation groove 102 are arranged along the long axis direction of the electronic cigarette 1000, and the opening end faces of the induction air passage 105 and the first accommodation groove 102 are in the same plane, facilitating the connection between the opening ends of the induction air passage 105 and the first accommodation groove 102, reducing the possibility of the smoke liquid in the first accommodation groove 102 entering the induction air passage 105, and facilitating the production and manufacture of the housing 100.

[0038] In an alternative embodiment, the atomizer 500 of the electronic cigarette 1000 is detachably connected to the housing 100 of the power supply assembly 600, facilitating the transportation of the electronic cigarette 1000 after disassembly. In this embodiment, the accommodation cavity 103 is a threaded hole, and the atomizer 500 is provided with a stud adapted to the threaded hole. The housing 100 and the atomizer 500 are connected together by means of screw fastening, facilitating the close cooperation between the atomizer 500 and the power supply assembly 600. It can be understood that the atomizer 500 and the power supply assembly 600 can also be connected together by means of snap-fit. For example, the housing 100 is provided with a bayonet, and the atomizer 500 is provided with a boss adapted to the bayonet. By matching the bayonet with the boss, it is convenient to snap-connect the atomizer 500 and the housing 100. The connection relationship between the atomizer 500 and the power supply assembly 600 is not limited herein.

[0039] Please continue to refer to Figure 1 and Figure 2, in an alternative embodiment, a limiting member is further provided on the housing 100. The limiting member protrudes from the end face of the first accommodating groove 102 to enable the first accommodating groove 102 to communicate with the induction air passage 105, and the opening end of the induction air passage 105 is flush with the end face of the first accommodating groove 102. In this embodiment, the first accommodating groove 102 and the induction air passage 105 share the same end face, and the limiting member protrudes from the end face of the first accommodating groove 102. When the atomizer 500 of the electronic cigarette 1000 is fitted with the accommodating cavity 103 of the housing 100, when the atomizer 500 abuts against the limiting member, it indicates that the installation and fitting of the atomizer 500 and the power supply assembly 600 are completed. At this time, the atomizer 500 cannot continue to fit downward with the accommodating cavity 103 of the housing 100. Under the action of the limiting member, there will be a certain distance between the atomizer 500 and the end face of the first accommodating groove 102, which is convenient for the first accommodating groove 102 to store the leaked e-liquid from the atomizer 500, and is convenient for the first accommodating groove 102 to communicate with the opening end of the induction air passage 105, so as to facilitate the communication between the induction air passage 105 and the intake air passage of the atomizer 500.

[0040] It should be noted that when the intake air passage of the atomizer 500 of the electronic cigarette 1000 passes through the opening end of the induction air passage 105, the air pressure in the induction air passage 105 will change, which is detected by the trigger switch 300, and then the trigger switch 300 controls the atomizing core of the atomizer 500 to work to atomize the e-liquid. The intake air flow of the electronic cigarette 1000 will enter the first accommodating groove 102 after passing through the opening end of the induction air passage 105, and then enter the atomizing cavity 401 of the atomizer 500 from the oil leakage hole 401 in the atomizer 500 and mix with the atomized e-liquid.

[0041] Please continue to refer to Figure 4 and Figure 6 , in an alternative embodiment, the limiting member includes two convex platforms 106. The two convex platforms 106 are symmetrically and spaced apart, and the induction air passage 105 is located at the interval between the two convex platforms 106. When the atomizer 500 is fitted with the housing 100, it is convenient for the intake air passage to enter the first accommodating groove 102 through the interval between the two convex platforms 106 after passing through the opening end of the induction air passage 105, which is convenient for the first accommodating groove 102 and the induction air passage 105 to work independently without interference.

[0042] It can be understood that there are intervals at both ends of the convex platform 106, that is, the interval between the two convex platforms 106 forms an air flow channel. Among them, the opening end of the induction air passage 105 is located at one of the air flow channels, and the other air flow channel can be used to clean the leaked e-liquid in the first accommodating groove 102.

[0043] It should be noted that the first accommodating groove 102 is arranged in a cylindrical shape. The number of the convex platforms 106 included in the limiting member can also be multiple, for example, three or four, which is not limited herein. The convex platforms 106 can be arranged in an annular shape adapted to the first accommodating groove 102. When the number of the convex platforms 106 is multiple, several convex platforms 106 are evenly spaced and distributed at the end of the first accommodating groove 102. In this embodiment, the number of the convex platforms 106 is two, and the two convex platforms 106 are arranged at intervals, so that the air flow can only enter the first accommodating groove 102 from the interval between the two convex platforms 106. And the induction air duct 105 is arranged at the interval between the two convex platforms 106. Under the action of the convex platforms 106, the gas is guided to ensure that the trigger switch 300 can work normally. Among them, the distance between the two convex platforms 106 is greater than the diameter of the induction air duct 105, and the distance between the two convex platforms 106 is less than twice the diameter of the induction air duct 105, which is convenient for guiding the gas to achieve the effect of opening the trigger switch 300.

[0044] In an alternative embodiment, a groove (not shown in the figure) is further provided on the housing 100. The groove is located between the first accommodating groove 102 and the induction air duct 105 to connect the groove with the first accommodating groove 102 and the induction air duct 105. In this embodiment, the groove is arranged between the first accommodating groove 102 and the induction air duct 105, and the groove is located at the open end of the first accommodating groove 102. The groove connects the first accommodating groove 102 and the induction air duct 105, which is convenient for the air inlet channel to enter the first accommodating groove 102 after passing through the port of the induction air duct 105. It can be understood that the groove can also be a through hole, and the through hole connects the first accommodating groove 102 and the induction air duct 105. It is worth noting that the through hole is arranged close to the open end of the first accommodating groove 102, which is convenient for connecting the first accommodating groove 102 and the induction air duct 105, and for the first accommodating groove 102 to store excess smoke liquid.

[0045] Please continue to refer to Figure 4 and Figure 6, in an optional embodiment, a second accommodation groove 104 is further provided at one end of the accommodation cavity 103 opposite to the first accommodation groove 102. A liquid repellent channel 402 is provided on the positive electrode of the atomizer 500. When the power supply assembly 600 is connected to the atomizer 500, the positive electrode of the atomizer 500 abuts against the connecting member 200. In this embodiment, the leaked oil in the atomizer 500 enters the second accommodation groove 104 after passing through the liquid repellent channel 402. Under the action of the first accommodation groove 102 and the second accommodation groove 104, the leaked smoke liquid is prevented from entering the induction air passage 105 and the power supply assembly 600, ensuring the normal operation of the electronic cigarette 1000.

[0046] Please continue to refer to Figure 1 and Figure 2 , in an optional embodiment, the power supply assembly further includes a connecting member 200 electrically connected to the atomizer 500. The connecting member 200 is located at the bottom of the accommodation cavity 103. A liquid guiding groove 201 for the flow of smoke liquid is further provided at the connection position of the connecting member 200 and the atomizer 500. The liquid guiding groove 201 communicates with the second accommodation groove 104. In this embodiment, the connecting member 200 is installed at one end of the accommodation cavity 103 away from the atomizer 500. The accommodation cavity 103 has opposite ends. The connecting member 200 is installed at one end of the accommodation cavity 103 away from the atomizer 500, that is, the connecting member 200 is installed at the bottom of the accommodation cavity 103. During the cooperation of the atomizer 500 and the accommodation cavity 103, the connecting member 200 is electrically connected to the atomizer 500.

[0047] It is worth noting that the housing 100 can be used as the negative electrode of the power supply assembly 600 to conduct electricity with the atomizer 500, and the connecting member 200 can be used as the positive electrode of the power supply assembly 600 to conduct electricity with the atomizer 500. The connecting member 200 can be a conductive spring needle, which is convenient for the conductive contact between the connecting member 200 and the atomizer 500, avoiding the problem of poor contact. It can be understood that using the housing 100 and the connecting member 200 as the electrodes of the power supply assembly 600 is convenient for reducing the manufacturing difficulty of the electronic cigarette 1000 and making it easy to implement in terms of the structure of the electronic cigarette 1000.

[0048] Please continue to refer to Figure 2, in this embodiment, the connecting member 200 is further provided with a liquid guiding groove 201 facilitating the flow of e-liquid at the connection end with the atomizer 500. The liquid guiding groove 201 is disposed on the mating end of the connecting member 200 with the atomizer 500. After the leaked e-liquid passes through the liquid drainage channel 402, it moves to the free end of the connecting member 200, and then under the action of the liquid guiding groove 201, the leaked e-liquid moves to the second accommodation groove 104, facilitating the storage of the leaked e-liquid and ensuring the normal operation of the electronic cigarette 1000. It can be understood that the liquid guiding groove 201 can be arranged in a cross shape, or the liquid guiding groove 201 is arranged in a Y shape. In this embodiment, the liquid guiding groove 201 is arranged in a cross shape, facilitating the diversion of the leaked e-liquid and ensuring the conductive area of the connecting member 200 to ensure conductive contact between the connecting member 200 and the atomizer 500.

[0049] Please continue to refer to Figure 4 and Figure 6 , in an alternative embodiment, the free end of the housing 100 is further provided with an accommodation space 101 for receiving the atomizer 500, and the induction air passage 105 is in communication with the accommodation space 101.

When the atomizer 500 is installed and mated with the housing 100, the bottom of the atomizer 500 is received in the accommodation space 101, and the accommodation space 101 protects the atomizer 500, and the atomizer 500 has a clearance fit with the side wall of the accommodation space 101, facilitating the atomizer 500 to intake air through the clearance. After the external air passes through the opening end of the induction air passage 105 through the clearance, it then passes through the first accommodation groove 102 and enters the atomization chamber 400 of the atomizer 500 from the oil drainage hole 401 of the atomizer 500.
