Referring to fig. 1-6, an embodiment of the invention provides a cartridge structure 100, which includes a housing 110, an atomizing core 120, a blocking component 130, a base component 140, and a thimble 150. The housing 110 has a receiving space 110a for storing an aerosol substrate. The atomizing core 120 has an atomizing space 120a for atomizing the aerosol substrate and an oil inlet hole 120b communicating the accommodating space 110a with the atomizing space 120a, the oil inlet hole 120b being for supplying the aerosol substrate. The plugging assembly 130 can move relative to the atomizing core 120 to plug or open the oil inlet hole 120 b. The base assembly 140 is fixedly coupled to the housing 110 and covers the receiving space 110 a. The thimble 150 penetrates through the base assembly 140 and is capable of moving relative to the base assembly 140, and is used to drive the plugging assembly 130 to move away from the base assembly 140, so as to separate the oil inlet hole 120b from the plugging of the plugging assembly 130.

According to the cartridge structure 100 provided in the above embodiment, during transportation, the blocking component 130 blocks the oil inlet 120b of the atomizing core 120, and the accommodating space 110a is isolated from the atomizing space 120a, so that the aerosol substrate is blocked in the accommodating space 110a, thereby preventing the aerosol substrate from entering the atomizing core 120 and then overflowing from the atomizing core 120 to the outside of the cartridge structure 100. When the aerosol structure 100 is inserted into the host 200 providing power to the aerosol structure 100, the thimble 150 is acted by the force toward the accommodating space 110a, and under the action, the thimble 150 moves toward the accommodating space 110a and drives the blocking assembly 130 to move relative to the atomizing core 120, so that the oil inlet 120b is separated from the blocking of the blocking assembly 130. Compared with the prior art, the cartridge structure 100 provided by the embodiment solves the problem of aerosol substrate leakage, and is more convenient to use without adding extra actions before use.

It should be noted that the atomizing core 120 mainly heats the liquid aerosol substrate through the internal heating structure, and the obtained substance is mixed with air, so as to obtain the atomized aerosol substrate. Thus, the atomizing wick 120 needs to be in communication with the external space, thereby tending to cause the aerosol substrate to flow out of the cartridge structure 100 through the atomizing wick 120.

In addition, the aerosol substrate mentioned in the embodiments of the present invention may be, but is not limited to, tobacco tar.

Referring to fig. 2 to 4, in an embodiment of the invention, the base assembly 140 includes a mounting member 142 fixedly connected to the housing 110 and a deformable sealing member 144 disposed near the accommodating space 110a, the mounting member 142 is provided with a first through hole 142a, the sealing member 144 is provided with a second through hole 144a communicated with the first through hole 142a and the accommodating space 110a, the first through hole 142a and the second through hole 144a are used for the thimble 150 to pass through, and when the thimble 150 is disposed in the second through hole 144a, the sealing member 144 deforms and supports the thimble 150.

In the present embodiment, the manner of restraining the thimble 150 by the sealing member 144 can be inferred from the assembling manner, which can firstly complete the assembling of the plugging element 130, the base element 140 and the housing 110, and then complete the assembling of the thimble 150. Thus, the assembly process of the cigarette bullet structure 100 is not changed or the assembly difficulty is increased due to the addition of the thimble 150, and the thimble 150 is only required to be placed in the second through hole 144a to complete the assembly when the thimble 150 is assembled.

Of course, in this embodiment, the size of the second through hole 144a needs to be designed, so as to achieve the function of supporting the thimble 150, and at the same time, the thimble 150 can slide in the second through hole 144a under the external force.

Preferably, the seal 144 is rubber.

In one embodiment, when the thimble 150 is not inserted into the base assembly 140, the first through hole 142a and the second through hole 144a form an oil injection passage for the aerosol substrate to enter the accommodating space 110 a. In the smoke cartridge structure 100 provided by this embodiment, the first through hole 142a and the second through hole 144a for assembling the thimble 150 are used as oil injection holes, and the thimble 150 is placed after oil injection is completed, so as to block the accommodating space 110 a. The structure of the cartridge 100 is simplified by such a way that the cartridge is multipurpose, and the cartridge structure 100 is more ingenious.

In another embodiment, when the oil inlet hole 120b is blocked by the blocking assembly 130 and the thimble 150 abuts against the blocking assembly 130, the thimble 150 is received in the base assembly 140. Such that the arrangement facilitates presentation of the cartridge structure 100.

In a more specific embodiment, the base assembly 140 further includes a magnetic member 160 for magnetically connecting with an external device and located at an end of the mounting member 142 away from the sealing member 144, the magnetic member 160 is opened with a third through hole 160a communicating with the first through hole 142a, and the third through hole 160a is used for allowing the external device to enter to push the thimble 150. It should be noted that, in this embodiment, the external device enters the third through hole 160a of the magnetic member 160 and is magnetically connected with the external device, so that the connection stability of the cartridge structure 100 and the external device can be enhanced. The external device may be a host 200 that provides power to the cartridge structure 100.

Of course, in other embodiments, the cartridge structure 100 and the host 200 may be connected by a snap-fit manner.

Thus, the plugging member 132 does not need any other fixing structure, and the oil inlet hole 120b can be plugged by its own elasticity, and the sliding of the plugging member 132 is facilitated.

Preferably, the blocking member 132 is a rubber member.

In a specific embodiment, when the thimble 150 does not push the pushing element 134, the blocking element 132 and the sealing element 144 respectively support the pushing element 134 at two sides, the pushing element 134 is provided with a fourth through hole 134a facing the second through hole 144a and used for the aerosol substrate to pass through, and a cross-sectional area of one end of the fourth through hole 134a close to the second through hole 144a is smaller than a cross-sectional area of one end of the thimble 150 close to the pushing element 134. It is worth mentioning that the aerosol substrate can enter the accommodating space 110a through the fourth through hole 134a, and the size of the fourth through hole 134a does not interfere with the movement of the pushing member 134 by the thimble 150, which is skillfully designed.

Referring to fig. 2-4 again, in another embodiment of the present invention, the housing 110 further defines an exhaust channel 110b communicating with the atomizing space 120a, and the exhaust channel 110b is used for outputting the atomized aerosol substrate.

Further, the exhaust passage 110b is located in the middle of the housing 110 and extends to an end of the housing 110 away from the base.

Furthermore, in order to prevent the aerosol matrix from overflowing at the interface between the atomizing core 120 and the air discharge channel 110b, the cartridge structure 100 is further provided with a connecting member 170 made of silica gel and connecting the atomizing core 120 and the air discharge channel 110 b.

Referring to fig. 1 to 6, another embodiment of the present invention further provides an aerosol generating device, including the cartridge structure 100 provided according to any of the above embodiments and a host 200 connected to the cartridge structure 100 and used for providing power, wherein the host 200 is provided with an ejector 210, and when the cartridge structure 100 is connected to the host 200, the ejector 210 drives the thimble 150 to move, so that the oil inlet 120b is separated from the plugging of the plugging component 130.

In a specific embodiment, a groove adapted to the cartridge structure 100 is formed at an end of the main body 200 close to the cartridge structure 100, and when the cartridge structure 100 is inserted into the groove, the ejector 210 faces the thimble 150.

Further, the outer circumference of the cartridge structure 100 is provided with a stepped insertion portion 110c, and when the insertion portion 110c is inserted into the groove, the oil inlet hole 120b is also separated from the sealing of the sealing component 130.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention, and it is therefore to be understood that the invention is not limited by the scope of the appended claims.
