[0039] Please refer to Figure 1. An embodiment of the present application provides an atomization device 100 for heating and atomizing an atomized liquid to generate an aerosol for a user to take, wherein the atomized liquid includes but is not limited to liquid medicines and oils used in the fields of medical treatment, beauty, and health care. The heating method can be convection, conduction, radiation, or a combination thereof, which is not limited here.

[0040] As described in the background technology, some atomizing devices in the related art are provided with a liquid storage bottle for replenishing the atomizing liquid. When the atomizing liquid in the liquid storage part is exhausted, the user can invert the atomizing device to replenish the atomizing liquid in the liquid storage bottle into the liquid storage part so that the atomizing device can work normally.

[0041] However, due to the structural defects of the existing atomizer device, when the atomizer device is inverted to replenish liquid, the atomized liquid cannot smoothly enter the liquid storage component due to the internal and external pressure difference, which brings inconvenience to the use of the atomizer device.

[0042] In order to solve the above technical problems, as shown in Figure 2 and Figure 3 As shown, the atomizing device 100 includes a liquid storage chamber 20a, a liquid storage bottle receiving position 10a, and a ventilation channel. The liquid storage bottle receiving position 10a is located at one side of the liquid storage chamber 20a and communicates with the liquid storage chamber 20a. The liquid storage bottle receiving position 10a is used to receive a liquid storage bottle 70, and the liquid storage bottle 70 received in the liquid storage bottle receiving position 10a is communicated with the liquid storage chamber 20a. The ventilation channel is located at one side of the liquid storage chamber 20a away from the liquid storage bottle receiving position 10a, and the ventilation channel communicates the liquid storage chamber 20a with the external atmosphere.

[0043] When the atomizer 100 is in a normal placement and use state, the liquid storage chamber 20a is located above the liquid storage bottle accommodating position 10a. When the atomizer 100 is in an inverted liquid replenishing state, the liquid storage chamber 20a is located below the liquid storage bottle accommodating position 10a, and the atomized liquid in the liquid storage bottle 70 is replenished into the liquid storage chamber 20a.

[0044] During the fluid replenishment process, since the ventilation channel connects the liquid storage chamber 20a with the external atmosphere, the air in the liquid storage chamber 20a can be discharged into the external atmosphere through the ventilation channel, so that the air pressure inside the liquid storage bottle 70 and the liquid storage chamber 20a is balanced with the air pressure of the external atmosphere, thereby promoting the smooth replenishment of the atomized liquid into the liquid storage chamber 20a without the formation of a liquid film to block the flow of the atomized liquid, thereby improving the user experience of the atomization device 100.

[0045] Please continue to refer to Figure 2 and Figure 3 , the atomizing device 100 is roughly in a cubic structure. In the following embodiments, the length direction of the atomizing device 100 is defined as the first direction (i.e., the X direction in FIG. 1 ), the height direction of the atomizing device 100 is defined as the second direction (i.e., the Y direction in FIG. 1 ), and the width direction of the atomizing device 100 is defined as the third direction (i.e., the Z direction in FIG. 1 ). The first direction, the second direction, and the third direction intersect each other. As a preferred embodiment, the first direction, the second direction, and the third direction are perpendicular to each other. It can be understood that the overall shape of the atomizing device 100 is not limited and can be set as needed.

[0046] The atomizing device 100 includes a support frame 10, an atomizing housing 20, an atomizing tube 30, a nozzle assembly 60, an atomizing core 50, a liquid storage bottle 70, and a power supply assembly 80. The support frame 10, the atomizing housing 20, the atomizing tube 30, and the nozzle assembly 60 are mutually matched to form a liquid storage chamber 20a, a liquid storage bottle accommodating position 10a, and a power supply accommodating chamber 10b. The atomizing core 50 is accommodated in the atomizing tube 30 for heating the atomized liquid, the liquid storage bottle 70 is detachably accommodated in the liquid storage bottle accommodating position 10a for storing the atomized liquid, and the power supply assembly 80 is accommodated in the power supply accommodating chamber 10b to supply power to the atomizing core 50. Similarly, the power supply assembly 80 can also be detachably accommodated in the power supply accommodating chamber 10b.

[0047] As for the ventilation channel, the ventilation channel can be formed on the side wall surface of the atomizing housing 20 corresponding to the liquid storage chamber 20a, that is, by setting a through hole on the side wall surface of the atomizing housing 20, the ventilation channel connects the liquid storage chamber 20a with the external atmosphere. Alternatively, the ventilation channel is formed on the top wall surface of the atomizing housing 20 corresponding to the liquid storage chamber 20a, that is, by setting a through hole on the top wall surface of the atomizing housing 20, and further, the outer side of the top wall surface of the atomizing housing 20 can be provided with a suction nozzle assembly 60 that cooperates with it, and then the ventilation channel is partially formed in the through hole on the top wall surface of the atomizing housing 20, and partially formed in the channel inside the suction nozzle assembly 60 docking with the through hole, thereby, the liquid storage chamber 20a is connected to the external atmosphere via the top wall surface of the atomizing housing 20 and the internal channel of the suction nozzle assembly 60. Alternatively, the ventilation channel can also be formed at the atomizer tube 20 that cooperates with the liquid storage chamber 20a, in the gap between the atomizer tube 20 and the liquid storage chamber 20a; or the atomizer tube 20 is grooved, so that the ventilation channel can also be formed in the air flow channel 30a in the atomizer tube 20.

[0048] The support bracket 10 is a shell-shaped structure, and the support bracket 10 is structured to form a liquid storage bottle accommodating position 10a and a power supply accommodating cavity, and the liquid storage bottle accommodating position 10a and the power supply accommodating cavity 10b are arranged adjacent to each other in the first direction. It can be understood that the shape of the support bracket 10 is not limited, and can be arranged as needed to play the role of fixing, connecting, protecting, etc.

[0049] The liquid storage bottle 70 is a hollow bottle-shaped structure, and the liquid storage bottle 70 can be detachably installed in the liquid storage bottle accommodating position 10a. When the atomizing device 100 is not in use during transportation, sales, etc., the liquid storage bottle 70 can be separated from the supporting frame 10 so that the two can be stored separately. When the atomizing device 100 needs to be used, the liquid storage bottle 70 can be installed in the liquid storage bottle accommodating position 10a to supply liquid to the atomizing core 50.

[0050] As a preferred embodiment, the support bracket 10 is further provided with a piercing portion in a needle shape or other shapes. When the liquid storage bottle 70 is installed in the liquid storage bottle accommodating position 10a, the piercing portion can pierce one end of the liquid storage bottle 70 to allow the atomized liquid to flow out of the liquid storage bottle 70. Since the liquid storage bottle 70 needs to be pierced by the piercing portion to be opened, when the atomizing device 100 is in the process of transportation and sales, the liquid storage bottle 70 can remain in a closed state to prevent the atomized liquid from leaking.

[0051] The atomizing housing 20 is configured and connected to one side of the supporting frame 10 in the third direction, and includes an atomizing upper cover 21 and an atomizing base 23 that are mutually matched and connected. The atomizing upper cover 21 includes an upper cover top wall 212, an upper cover side wall 214, and a separator 216. The upper cover side wall 214 extends from the edge of the upper cover top wall 212 along the third direction toward one side of the upper cover top wall 212. The separator 216 is located on the inner side of the upper cover side wall 214. The separator 216 extends from the upper cover top wall 212 along the extension direction of the upper cover side wall 214 to form an annular structure. The atomizer base 23 is configured to be connected to one end of the upper cover side wall 214 away from the upper cover top wall 212, and one end of the partition 216 away from the upper cover top wall 212 is abutted against the atomizer base 23. The partition 216, the upper cover top wall 212 and the atomizer base 23 are enclosed together to form a receiving space. A wall surface of the atomizer housing 20 is provided with a connecting hole 212a, and the connecting hole 212a is connected to the receiving space. Specifically in one embodiment, the connecting hole 212a is opened at the center of the upper cover top wall 212.

[0052] In this way, the atomizer shell 20 is connected to the side of the support frame 10 away from the connecting hole 212a in the third direction through the atomizer base 23, and the atomizer base 23 and the support frame 10 together form a liquid inlet channel connecting the open end of the liquid storage bottle 70 and the accommodating space, and the atomized liquid in the liquid storage bottle 70 can enter the accommodating space through the liquid inlet channel.

[0053] Please refer to Figure 2. Figure 3 As shown in FIG. 4 , the atomizer tube 30 is a hollow tubular structure, and the atomizer tube 30 is arranged in the accommodating space, one end of the atomizer tube 30 is connected to the connecting hole 212a along the third direction, and the other end of the atomizer tube 30 is connected to the atomizer base 23 along the third direction. An air flow channel 30a extending along the third direction is formed in the atomizer tube 30, and a liquid storage chamber 20a surrounding the outside of the atomizer tube 30 along the circumferential direction is formed between the atomizer tube 30 and the atomizer housing 20. Further, the tube wall of the atomizer tube 30 is provided with a liquid inlet 30b connecting the liquid storage chamber 20a and the air flow channel 30a, so that the atomized liquid in the liquid storage chamber 20a can enter the atomizer tube 30 through the liquid inlet 30b. It can be understood that the number, shape and arrangement of the liquid inlet 30b are not limited, and can be set as needed to meet different requirements.

[0054] Please continue to refer to Figure 2 and Figure 3The liquid storage member 40 is disposed in the liquid storage cavity 20a. The liquid storage member 40 is provided with a mounting through hole extending along the third direction. The mounting through hole cooperates with the installation of the atomizing tube 30, and the mounting through hole is directly opposite to the connecting hole 212a, so one end of the atomizing tube 30 passes through the mounting through hole and is connected to the connecting hole 212a. The liquid storage member 40 can be formed of a porous material with good absorption effect such as organic cotton, so after the atomized liquid in the liquid storage bottle 70 flows into the liquid storage cavity 20a, it can be absorbed by the liquid storage member 40 and stored in the liquid storage member 40. It can be understood that the material forming the liquid storage member 40 is not limited, and the liquid storage member 40 can also be a single-layer or multi-layer structure to meet the requirements of different liquid supply rates.

[0055] The atomizer core 50 is accommodated in the air flow channel 30a of the atomizer tube 30, and the atomizer core 50 is a hollow columnar structure, including a heating element and a liquid guide element coated outside the heating element. The liquid guide element is formed by a porous material with good liquid guide performance such as organic cotton, and the atomized liquid entering the atomizer tube 30 through the liquid inlet 30b is uniformly guided to the surface of the heating element through the liquid guide element. The heating element is electrically connected to the power supply assembly 80, and the heating element can generate heat and heat the atomized liquid to generate an aerosol under the action of the electric energy of the power supply assembly 80. The airflow of the external atmosphere can enter the air flow channel 30a of the atomizer tube 30 through the atomizer base 23, and then carry the aerosol generated by the atomization of the atomized liquid out of the air flow channel 30a. It can be understood that the specific structure of the atomizer core 50 is not limited to this, and can be set as needed to meet different atomization requirements.

[0056] The nozzle assembly 60 is configured to be connected to the wall surface of the atomizer housing 20 having the connecting hole 212a, and the nozzle assembly 60 is structured to form an exhaust channel 60a that is arranged along the third direction, one end of the exhaust channel 60a is connected to the airflow channel 30a, and the other end of the exhaust channel 60a is connected to the external atmosphere, so that the aerosol in the airflow channel 30a can be discharged through the exhaust channel 60a, and the user can inhale the aerosol through the nozzle assembly 60. Specifically in one embodiment, the nozzle assembly 60 includes a nozzle body and a nozzle seal provided at one end of the nozzle body, and the nozzle body is sealed and connected to the atomizer upper cover 21 through the nozzle seal.

[0057] In the present application, the ventilation channel is formed at the connection between the atomizing tube 30 and the communicating hole 212a. It can be understood that the specific formation method and formation position of the ventilation channel can be set according to the specific structure of the connection between the atomizing tube 30 and the communicating hole 212a.

[0058] As shown in Figure 2, Figure 3As shown in FIG. 5 , FIG. 5 shows the direction of airflow during the injection process. In the first embodiment of the present application, the diameter of the atomizing tube 30 is smaller than the diameter of the communicating hole 212a, so a ventilation gap 30d is formed between the tube wall of the atomizing tube 30 and the hole wall of the communicating hole 212a, and the ventilation gap 30d is connected to the liquid storage chamber 20a, and the ventilation gap 30d surrounds the atomizing tube 30 in the circumferential direction. Due to the installation error, the atomizing tube 30 and the atomizing upper cover 21 are easily abutted to form a seal, so that the ventilation gap 30d is too small or even disappears, and the ventilation function cannot be met. In order to solve this technical problem, a notch is set for the position of the atomizing tube 30 and the communicating hole 212a. Specifically, the tube wall of the atomizing tube 30 inserted at one end of the communicating hole 212a is provided with a first ventilation groove 30c, and the first ventilation groove 30c connects the ventilation gap 30d and the airflow channel 30a, and the ventilation gap 30d and the first ventilation groove 30c together form a ventilation channel.

[0059] Thus, as shown in FIG. 5 , during the inverted liquid injection process, the gas in the liquid storage chamber 20a flows into the air flow channel 30a through the ventilation gap 30d and the first ventilation groove 30c in sequence, and finally flows out through the exhaust channel 60a.

[0060] In some embodiments, the atomizer tube 30 is provided with at least two first ventilation grooves 30c, and all the first ventilation grooves 30c are arranged at intervals along the circumference of the atomizer tube 30. It can be understood that the number, shape and arrangement of the first ventilation grooves 30c are not limited, and can be arranged as needed to meet the requirements of different ventilation volumes. Specifically in one embodiment, the atomizer tube 30 is provided with two first ventilation grooves 30c, each of which is a rectangular empty groove connected to the end wall of one end of the atomizer tube 30, and the two first ventilation grooves 30c are relatively arranged on opposite sides of the atomizer tube 30 in the second direction.

[0061] Please refer to Figures 6, 7 and 8. In the second embodiment of the present application, the aperture of the end of the connecting hole 212a close to the liquid storage chamber 20a is larger than the diameter of the atomizing tube 30, and the aperture of the end of the connecting hole 212a away from the liquid storage chamber 20a is substantially the same as the diameter of the atomizing tube 30, so a first ventilation gap 30e is provided between the tube wall of the atomizing tube 30 and the hole wall of the connecting hole 212a, the first ventilation gap 30e is communicated with the liquid storage chamber 20a, and the first ventilation gap 30e circumferentially surrounds the atomizing tube 30. A second ventilation gap 212c is provided between the end wall of the upper cover top wall 212 away from the atomizing base 23 and the suction nozzle assembly 60, and the second ventilation gap 212c is connected to the external atmosphere. A second ventilation groove 212b is formed on the wall of the communication hole 212a. The second ventilation groove 212b connects the first ventilation gap 30e and the second ventilation gap 212c. The first ventilation gap 30e and the second ventilation groove 212b together form a ventilation channel.

[0062] Thus, during the inverted liquid injection process, the gas in the liquid storage chamber 20a passes through the first ventilation gap 30e, the second ventilation groove 212b, the second ventilation gap 212c in sequence, and finally flows out from the gap between the top wall 212 of the upper cover and the suction nozzle assembly 60.

[0063] Specifically in some embodiments, the second ventilation gap 212c is formed by a groove opened in the atomizing housing 20. More specifically in one embodiment, the hole wall of the communicating hole 212a is opened with two second ventilation grooves 212b. Two second ventilation gaps 212c are formed between the atomizing housing 20 and the suction nozzle assembly 60, and the two second ventilation gaps 212c are symmetrically arranged on opposite sides of the communicating hole 212a in a radial direction, and each second ventilation gap 212c is connected to a second ventilation groove 212b.

[0064] As a preferred embodiment, the two second ventilation grooves 212b are spaced apart on both sides of the connecting hole 212a in the second direction, and the two second ventilation gaps 212c are located on opposite sides of the connecting hole 212a in the second direction. One end of each second ventilation gap 212c is connected to the second ventilation groove 212b, and the other end extends along the second direction to the edge of the top wall 212 of the upper cover.

[0065] In addition, the second ventilation gap 212c can also recover the condensed liquid generated in the suction nozzle assembly 60, thereby preventing the condensed liquid from flowing out of the atomization device 100 through the suction nozzle assembly 60 and affecting the user's experience.

[0066] The above-mentioned atomizer device 100 has a ventilation channel connected to the external atmosphere at one end of the liquid storage chamber 20a away from the liquid storage bottle 70. Therefore, when the atomizer device 100 is inverted so that the liquid storage bottle 70 replenishes the liquid in the liquid storage chamber 20a, excess gas can flow out through the ventilation channel to balance the air pressure inside and outside the atomizer device 100, so that the atomized liquid can be smoothly replenished into the liquid storage part 40 of the liquid storage chamber 20a, thereby improving the user experience of the atomizer device 100.

[0067] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
