TECHNICAL FIELD

The present disclosure belongs to the field of electronic atomizing technology, and in particular, relates to an atomizing device that facilitates the replacement of atomizing cartridges.

BACKGROUND

Atomizing device is an electronic device used to convert its own stored liquid to be atomized into an aerosol that can be inhaled by the user. A power supply assembly and an atomizing assembly are provided inside the atomizing device. The power supply assembly is used to supply power to the atomizing assembly. A liquid storage cavity and an atomizing core are provided in the atomizing assembly. The liquid to be atomized is stored in the liquid storage cavity. The liquid to be atomized can enter the atomizing core from the liquid storage cavity, and then the atomizing core converts the liquid to be atomized into the aerosol. It can be seen that the amount of aerosol that the atomizing device can generate is determined by the amount of liquid to be atomized stored inside, and the taste of the aerosol converted by the atomizing device is also determined by the type of liquid to be atomized.

In order to meet the needs of the number of times of large inhalation and multiple flavors, atomizing devices with multiple liquid storage cavities for storing liquids of different flavors to be atomized have appeared on the market. In this kind of multi-flavor atomizing device, after the liquid to be atomized in any liquid storage cavity is used up or when the inhaling flavor needs to be changed, the operation of replacing the liquid to be atomized needs to be performed. However, due to the need to ensure the sealing of the liquid storage cavity and other factors, the operation process of replacing the liquid to be atomized in this multi-flavor atomizing device is relatively complicated, which is disadvantageous to user operation.

Referring to FIGS. 2, 5 and 10, in an embodiment, the mounting base 140 is provided with a mounting hole 141 in communication with the accommodating cavity 111. An outer surface of the bottom of the liquid storage cup 210 is provided with a connecting shaft 230 protruding outwardly. The connecting shaft 230 is rotatably inserted into the mounting hole 141, so that the liquid storage cup 210 can rotate relative to the power supply assembly 100, thus the user can change the position of the atomizing cartridge 220 mounted in the liquid storage cup 210 relative to the power supply assembly 100 and relative to the nozzle assembly 300 by rotating the liquid storage cup 210.

Referring to FIG. 10, in an embodiment, the mounting base 140 is provided with a limiting groove 142 on a side of the mounting hole 141 away from the accommodating cavity 111. The connecting shaft 230 is provided with a connecting hole 231 in its axial direction. The atomizing assembly 200 further includes a limiting member 240. One end of the limiting member 240 is fixedly connected to the connecting hole 231, another end of the limiting member 240 is provided with a first limiting structure. The first limiting structure is mounted in the limiting groove 142. The first limiting structure is limited to the bottom of the limiting groove 142 in a direction from the limiting groove 142 to the outlet 116, so that the connecting shaft 230 can be limited to the bottom of the limiting groove 142 in a direction from the limiting groove 142 to the outlet 116, that is, the connecting shaft 230 can be limited in the mounting hole 141 in a direction from the mounting hole 141 to the outlet 116. In addition, since the connecting shaft 230 is a part of the liquid storage cup 210, and the mounting hole 141 is in communication with the accommodating cavity 111, the liquid storage cup 210 can be limited in the accommodating cavity 116 in a direction from the accommodating cavity 111 to the outlet 116.

Specifically, in this embodiment, the limiting member 240 is a threaded connector, which includes a rod portion and a head portion connected to each other. The rod portion is fixedly connected to the connecting hole 231, and the head portion is the first limiting structure. Moreover, in order to smoothly rotate the liquid storage cup 210 and prevent the liquid storage cup 210 from being stuck by the first limiting structure, a gap is provided between the head portion of the threaded connector and the bottom of the limiting groove 142. During assembling of the atomizing device 1, the connecting shaft 230 is firstly rotatably inserted into the mounting hole 141, and then the rod portion of the threaded connector is fixedly connected to the connecting hole 231 of the connecting shaft 230 in a direction of the limiting groove 142, and the head portion of the threaded connector is mounted in the limiting groove 142, and finally the mounting base 140, the microphone silicone 130, the bottom cover 120, and other components are mounted on the outside of the threaded connector.

In some other embodiments, the mounting base 140 is provided with the limiting groove 142 on the side of the mounting hole 141 away from the accommodating cavity, and one end of the connecting shaft 230 extends through the mounting hole 141, and is inserted into the limiting groove 142.

In addition, since the connecting shaft 230 is a part of the liquid storage cup 210, and the mounting hole 141 is in communication with the accommodating cavity 111, the liquid storage cup 210 can be limited in the accommodating cavity 111 in the direction from the accommodating cavity 11 to the outlet 113. As an example, the second limiting structure may be a limiting protrusion provided on the connecting shaft 230.

In some other embodiments, the connecting shaft 230 is configured to be limited into the mounting hole 141 in the direction from the mounting hole 141 to the outlet 116. Since the connecting shaft 230 is a part of the liquid storage cup 210 and the mounting hole 141 is in communication with the accommodating cavity 111, the liquid storage cup 210 can be limited in the accommodating cavity 111 in the direction from the accommodating cavity 111 to the outlet 116. As an example, an annular groove can be provided on a sidewall of the mounting hole 141, and an annular protrusion can be provided on the connecting shaft 230. By mounting the annular protrusion into the annular groove, the connecting shaft 230 can be limited in the mounting hole 141.

Referring to FIGS. 4, 5 and 7, in an embodiment, the liquid storage cup 210 is provided with four mounting cavities 211. Four atomizing cartridges 220 are mounted in the four mounting cavities 210 respectively. One of the four atomizing cartridges 220 is in a position that it can electrically connected to the power supply assembly 100. The atomizing cartridge 220 that is electrically connected to the power supply assembly 100 is also in a position that it can be connected to the nozzle assembly 300.

It should be understood that since the atomizing cartridge 220 is mounted in the mounting cavity 211 in the liquid storage cup 210, and the liquid storage cup 210 is rotatably connected to the power supply assembly 100 through the connecting shaft 230, a position of the atomizing cartridge 200 relative to the power supply assembly 100 can be changed by rotating the liquid storage cup 210, so that the atomizing cartridge 220 that is electrically connected to the power supply assembly 100 and connected to the nozzle assembly 300 is switchable. That is, the user can switch between the atomizing cartridges 220 by rotating the liquid storage cup 210. When the types of atomizing cartridges 220 provided in the mounting cavities 211 of the liquid storage cup 210 are different, the user can switch between the atomizing cartridges 220 by rotating the liquid storage cup 210, so as to switch between different aerosol flavors for inhalation.

The operating window 112 is in communication with the accommodating cavity 111. The operating window 112 is configured for the user to rotate the liquid storage cup 210. A wall surface of the liquid cup 210 is provided with an observation window 212 corresponding to each of the mounting cavities 211. A casing of the atomizing cartridge 220 is made of transparent material. The user can rotate the liquid storage cup 210 via the operation window 112, and the user can also observe the amount of remaining liquid to be atomized inside the atomizing cartridge 220 via the operation window 112 and the observation window 212.

In an embodiment, a surface of the casing of the atomizing cartridge 220 is engraved with a name mark indicating the type of liquid to be atomized stored in it, so that the user can select different types of the atomizing cartridges 220 via the operation window 112 and the observation window 212 when switching between the atomizing cartridges 220.

Referring to FIGS. 6 to 7, in an embodiment, the bottom of the atomizing cartridge 20 is provided with a second electrical contact 222 for electrical connection with a first electrical contact 143 of the power supply assembly 100, and an air inlet structure 223 configured to be in communication with the air inlet hole 144 of the power supply assembly 100. The bottom of the liquid storage cup 210 is provided with a communication hole 215 to allow the second electrical contact 222 of the atomizing cartridge 220 and the air inlet structure 223 to extend through.

Referring to FIG. 7, in an embodiment, the liquid storage cup 210 is cylindrical in shape, and the liquid storage cup 210 is provided with two partition plates 213 intersecting with each other. The two partition plates 213 and the inner wall of the liquid storage cup 210 enclose four mounting cavities 211.

Specifically, in this embodiment, the accommodating cavity 111 is cylindrical in shape, the liquid storage cup 210 is cylindrical in shape, a cross-sectional shape of the mounting cavity 211 is fan-shaped, and a cross-sectional shape of the atomizing cartridge 220 is also fan-shaped. It should be understood that the cylindrical accommodating cavity 111 is easy to process and manufacture, the cylindrical liquid storage cup 210 is easy for the user to rotate, and the cylindrical liquid storage cup 210 is convenient to be pinched out of the atomizing cartridge 220 or fallen out of the atomizing cartridge 220 by the user. The cross-section of the mounting cavity 211 is fan-shaped, which means that the mounting cavity 211 can be directly separated by the partition plate 213 provided in the liquid storage cup 210. The cross-section of the atomizing cartridge 220 is fan-shaped corresponding to the mounting cavity 211, which can facilitate the mounting of the atomizing cartridge 220 into the mounting cavity 211.

Referring to FIG. 1, in an embodiment, the outer surface of the liquid storage cup 210 is provided with a plurality of convex ribs 214 extending in a direction parallel to an axis direction of the liquid storage cup 210. The convex ribs 214 are configured to increase friction during user operation, and prevent slipping when operating the liquid storage cup 210 to rotate.

Referring to FIG. 5, in an embodiment, the outer surface of the liquid storage cup 210 is provided with a magnetic member 400 corresponding to each atomizing cartridge 220. For example, four magnetic members 400 are provided. Referring to FIG. 2, the power supply assembly 100 is provided with a magnetic fitting member 500 corresponding to each magnetic member 400 in the accommodating cavity 111. When the liquid storage cup 210 is stationary relative to the power supply assembly 100, the magnetic member 400 and the magnetic fitting member 500 are magnetically attracted to each other.

It should be understood that when rotating the liquid storage cup 210, under the action of the rotation torque, the magnetic member 400 can be separated from the magnetic fitting member 500; and during the process of rotating the liquid storage cup 210, when the magnetic member 400 approaches the magnet fitting member 500, since the mutual magnetic attraction force will be generated between the magnetic member 400 and the magnetic fitting member 500, the liquid storage cup 210 can be quickly and accurately positioned relative to the power supply assembly 100 due to the magnetic attraction force. This ensures that the magnetic member 400 corresponding to each atomizing cartridge 220 can be magnetically attracted to the magnetic fitting member 500 of the power supply assembly 100 after each rotation of the liquid storage cup 210, thereby ensuring that before and after rotating the liquid storage cup 210, there is always a position where the atomizing cartridge 220 is electrically connected to the power supply assembly 100 and in communication with the nozzle assembly 300.

Specifically, in this embodiment, the magnetic member 400 is fixedly provided on the outer surface of the bottom of the liquid storage cup 210, and the magnetic fitting member 500 is fixedly provided on the outer surface of the mounting base 140 facing the liquid storage cup 210.

In other embodiments, the outer surface of the liquid storage cup 210 is provided with a positioning groove corresponding to each atomizing cartridge 220, and the power supply assembly 100 is provided with an elastic contact in the accommodating cavity 111. The elastic contact can stretch and retract toward the positioning groove. When the liquid storage cup 210 is stationary relative to the power supply assembly 100, the elastic contact is mounted in the positioning groove.

It should be understood that when rotating the liquid storage cup 210, under the action of the rotation torque, the elastic contact can separate from the positioning groove; and in the process of rotating the liquid storage cup 210, when the positioning groove rotates above the elastic contact, the elastic contact will automatically extend into the positioning groove under the action of its own elastic force to realize the mounting of the elastic contact relative to the positioning groove. Through the mounting of the elastic contact relative to the positioning groove, it is possible to enable that after each rotation of the liquid storage cup 210, there is a positioning groove of the atomizing cartridge 220 for the positioning of the elastic contact of the power supply assembly, thereby ensuring that there is always a position where the atomizing cartridge 220 is electrically connected to the power supply assembly 100 and in communication with the nozzle assembly 300.

Specifically, a groove surface of the positioning groove is a spherical surface, and the shape of the elastic contact is spherical. By arranging the spherical positioning groove and the spherical elastic contact, the process of the elastic contact automatically extending into the positioning groove can be smoother and more successful, and the contact area between the elastic contact and the positioning groove is large, and the mounting is stable.

Referring to FIGS. 2 and 8 to 10, in an embodiment, the outlet 116 in communication with the accommodating cavity 111 is provided on the housing 110. Specifically, in this embodiment, the outlet 116 is a cylindrical channel defined in the housing 110 and located above the accommodating cavity 111. The cylindrical channel is in communication with the space outside the power supply assembly 100. The nozzle assembly 300 is detachably engaged with the outlet 116. The housing 110 is provided with an engaging protrusion 115 on the wall at the outlet 116. The outer surface of the nozzle assembly 300 is provided with an engaging groove 313. The nozzle assembly 300 is fixedly connected to the housing 100 in such a way that the engaging protrusion 115 is engaged with the engaging groove 313. By providing the engaging protrusion 115 and the engaging groove 313, the nozzle assembly 300 is relatively fixedly connected to the housing 110, which facilitates user operation and processing and manufacturing.

In an embodiment, the nozzle assembly 300 is rotatably engaged into the outlet 116. A length of the engaging groove 313 is greater than a length of the engaging protrusion 115 in a direction of the engaging groove 313, so that the engaging protrusion 115 is rotatable in the engaging groove 313, which can facilitate the user to operate the nozzle assembly 300 to be engaged in place through the rotational movement relative to the housing 110.

In an embodiment, a wall surface of the nozzle assembly 300 is also provided with an insertion groove 314. The insertion groove 314 is in communication with the engaging groove 313. The insertion groove 314 is arranged to extend in a height direction of the nozzle assembly 300 to an end of the nozzle assembly 300. The nozzle assembly 300 is inserted into the outlet 116 or separated from the outlet 116 in such a way that the engaging protrusion 115 is moved relative to the insertion groove 314, that is, the insertion groove 314 is configured to remove the nozzle assembly 300 from the housing 100 or mounting the nozzle assembly 300 to the housing 110.
