1 to 6, the electronic atomization device 10 provided by an embodiment of the present application includes an atomizer 100 and a power source 200, and the atomizer 100 and the power source 200 are detachably connected. The atomizer 100 is used to atomize liquids such as e-liquid, so as to form smoke for the user to inhale. The power supply 200 is used to supply power to the atomizer 100, and the atomizer 100 converts electric energy into heat energy required for atomization of the smoke liquid. The atomizer 100 includes an atomization core 120 and is provided with a first connection structure 110 corresponding to the atomization core 120. The power supply 200 includes a battery 220 and is provided with a second connection structure 210 corresponding to the battery 220. The first connection structure 110 and the second connection structure 210 can realize a detachable physical connection, and finally a detachable physical connection between the entire atomizer 100 and the power supply 200 can be realized. While the first connection structure 110 and the second connection structure 210 are physically connected, the battery 220 and the atomizing core 120 can be electrically connected through the first connection structure 110 and/or the second connection structure 210, so that the battery 220 can be connected to each other. The atomizing core 120 supplies power. That is, the battery 220 can supply power to the atomizing core 120 through the first connection structure 110, can also supply power to the atomizing core 120 through the second connection structure 210, and can also supply power through the first connection structure 110 and the second connection structure 210 at the same time.

Therefore, by providing the first connection structure 110 and the second connection structure 210, on the one hand, the physical connection between the entire atomizer 100 and the power supply 200 can be realized, and on the other hand, both the atomization core 120 and the battery 220 can be realized. The electrical connection between. When the atomizer 100 is fixed on the power supply 200, the battery 220 can supply power to the atomizer core 120, thereby atomizing the e-liquid in the atomizer core 120 to form smoke for the user to inhale. Combining the physical connection structure and the electrical connection structure into the same group of structures, that is, the same group of structures have the functions of both physical connection and electrical connection, which can simplify the structure of the entire electronic atomization device 10 and ensure that the electronic atomization device 10 has a compact structure And realize the miniaturization design. In addition, the reliability and stability of the physical connection and the electrical connection can be ensured, and the problems of intermittent power failure, unstable fixing of the atomizer 100 and inconvenient removal of the atomizer 100 can be prevented.

The power supply 200 has a second positioning surface 201, and the second positioning surface 201 may also be a flat surface. The first connection structure 110 is disposed on the first positioning surface 101, and the second connection structure 210 is disposed on the second positioning surface 201. When the first connecting structure 110 and the second connecting structure 210 are connected, the first positioning surface 101 and the second positioning surface 201 abut against each other, thereby providing a certain limit and support for the fixing of the atomizer 100.

1 to FIG. 8 and FIG. 10, in some embodiments, the first connection structure 110 is a socket 111 provided on the first positioning surface 101, and the socket 111 may be a circular hole. The second connection structure 210 is a plug post 211, and the plug post 211 protrudes a set length relative to the second positioning surface 201. The number of the pin 211 and the number of the socket 111 may be two respectively. The pin 211 is roughly cylindrical. The lower end of the pin 211 is electrically connected to the battery 220. The inserting post 211 encloses a cavity 211a, that is, the inserting post 211 is a hollow structure, and the inserting post 211 is also provided with a through groove 211b. The through groove 211b extends along the axial direction of the inserting post 211, and the through groove 211b is connected to the cavity at the same time. The cavity 211a is connected to the outside, so that the entire inserting post 211 has a certain elastic deformation function, and the through slot 211b and the cavity 211a provide a good avoidance space for the elastic deformation of the inserting post 211.

When the pin 211 is matched with the socket 111, the elastic deformation of the pin 211 can make the pin 211 and the socket 111 have a certain pressure, that is, the pin 211 and the socket 111 form a certain degree of interference. , In order to achieve a stable and reliable physical connection between the atomizer 100 and the power supply 200. After the plug pin 211 is matched with the socket 111, the end of the plug pin 211 and the atomizing core 120 can be electrically connected by abutting each other, thereby achieving an electrical connection between the battery 220 and the atomizing core 120. Since there is a certain degree of interference between the pin 211 and the socket 111, it is difficult for the pin 211 to shake in the socket 111, which in turn makes the pin 211 and the atomizing core 120 form a good contact relationship, and finally A stable and reliable electrical connection between the atomizing core 120 and the battery 220 is realized, and the intermittent power failure occurs when the plug 211 is separated from the atomizing core 120.

The two fixed sections 212a are arranged at intervals and are roughly linear. The two fixed sections 212a are fixed on the first section. On the two positioning surfaces 201 and the lower end is electrically connected to the battery 220, the connecting section 212b is connected to the ends of the two fixed sections 212a, that is, one end of the connecting section 212b is connected to the upper end of one of the fixed sections 212a, and the other of the connecting section 212b One end is connected to the upper end of another fixed section 212a, and the connecting section 212b may be curved. When the connecting section 212b is connected to the fixed section 212a, the entire second connecting structure 210 is roughly U-shaped. Similarly, because the two fixed sections 212a are arranged at a relative interval, the entire second connecting structure 210 has a certain elastic deformation function, and the gap between the two fixed sections 212a provides a good space for avoiding elastic deformation.

When the second connecting structure 210 is matched with the socket 111, a certain pressing force is formed between the two fixing sections 212a and the side wall of the socket 111, that is, the entire second connecting structure 210 and the socket 111 form a certain degree of interference. , In order to achieve a stable and reliable physical connection between the atomizer 100 and the power supply 200. After the second connection structure 210 is mated with the receptacle 111, the connecting section 212b and the atomizing core 120 can be electrically connected by abutting each other, thereby realizing the electrical connection between the battery 220 and the atomizing core 120. Since there is a certain degree of interference between the second connection structure 210 and the insertion hole 111, it is difficult for the second connection structure 210 to shake in the insertion hole 111, and the formation between the second connection structure 210 and the atomizing core 120 is good. The abutting relationship of, finally realizes a stable and reliable electrical connection between the atomizing core 120 and the battery 220, preventing the second connection structure 210 from being separated from the atomizing core 120 and intermittent power failure.

The first abutting member 113 has a substantially plate-like structure and is housed in a cavity surrounded by the first sleeve 112. The first abutting member 113 is electrically connected to the atomizing core 120. The second connecting structure 210 includes a second sleeve 213a and a second abutting member 213b. The second sleeve 213a is disposed on the second positioning surface 201 and protrudes to a certain height relative to the second positioning surface 201. The second abutment The member 213b is received in the cavity enclosed by the second sleeve 213a, and the second abutting member 213b is electrically connected to the battery 220. The cross-sectional size of the second sleeve 213a is smaller than the cross-sectional size of the first sleeve 112, so that the second sleeve 213a can be inserted in the first sleeve 112, and to a large extent realizes the entire atomizer 100 and the power supply. Stable and reliable physical connection between 200.

When the second sleeve 213a is mated with the first sleeve 112, the first abutting piece 113 is sandwiched in the second abutting piece 213b, so as to realize the contact between the first abutting piece 113 and the second abutting piece 213b. The electrical connection then realizes the stable and reliable electrical connection between the battery 220 and the atomizing core 120. In some embodiments, when the first abutting member 113 is sandwiched in the second abutting member 213b, it can also play a role in physically connecting the entire atomizer 100 and the power supply 200 to a certain extent. Of course, the positions of the first sleeve 112 and the first abutment 113 and the positions of the second sleeve 213a and the second abutment 213b can be interchanged, that is, the first sleeve 112 and the first abutment The member 113 is located on the second positioning surface 201, and the second sleeve 213 a and the second abutting member 213 b are located on the first positioning surface 101.

Through the mutual cooperation of the first guiding structure and the second guiding structure, a good guiding effect can be achieved, so that the first connecting structure 110 and the second connecting structure 210 are quickly and smoothly connected, and the relationship between the atomizer 100 and the power supply 200 is improved. The installation efficiency and precision of the machine can avoid the time consumed by multiple alignment and debugging.

The number of the guide posts 214 is two, and the two guide posts 214 are located on two sides of the second sleeve 213a. For example, the two guide posts 214 may be symmetrically arranged with respect to the second sleeve 213a. When the guide post 214 is matched with the guide hole 101a, the two can choose a clearance fit, thereby reducing the fitting resistance, making the guide post 214 easier to fit with the guide hole 101a, so as to smoothly realize the guiding effect.
