Description

Technical Field

[0001] The present utility model belongs to the field of heated tobacco devices, and particularly relates to the structure of a heated tobacco device with improved cleanability and dust-proof property of the ventilation passage.

Background Art

[0002] In conventional heated tobacco devices, such as electronic cigarettes, an air inlet communicating with an internal ventilation pipe is provided in the housing to allow smooth airflow. External air enters the ventilation passage through the air inlet and is atomized by an atomization unit to generate an aerosol. However, the air inlet of the conventional device has no dust-proof structure, and after long-term use, dust accumulates in the ventilation pipe, requiring cleaning. Moreover, since the ventilation pipe is enclosed in the housing, it is difficult to clean, and improvement is desired.

Summary of the Invention

[0003] An object of the present utility model is to solve at least one of the existing technical problems, and to provide a structure of a heated tobacco device with improved cleanability and dust-proof property of the ventilation passage in a heated tobacco device.

[0004] The technical means of the present utility model are as follows. The structure of a heated tobacco device with improved cleanability and dust-proof property of the ventilation passage according to the present utility model is characterized by including a heated tobacco device body, a housing, a dust-proof cover, and a positioning bottom cover. The housing is disposed on the outer periphery of the body, a ventilation pipe is provided on the body, a receiving groove is formed at the bottom of the housing, and a pipe orifice communicating with the bottom of the ventilation pipe is disposed on the groove surface of the receiving groove. The dust-proof cover is slidably provided left and right in the receiving groove and can cover or expose the pipe orifice. There is a gap between the periphery of the dust-proof cover and the inner surface of the receiving groove, which functions as an air inlet and communicates with the pipe orifice. The positioning bottom cover fits into the receiving groove and abuts against the right side of the dust-proof cover. When the positioning bottom cover is removed, the dust-proof cover can be slid to the right to expose the pipe orifice.

[0005] Compared with the prior art, the beneficial effects of this utility model are as follows. In this utility model, a slidable dust cover is provided at the bottom of the housing of the heated tobacco device to prevent dust in the airway by covering the pipe opening, or the pipe opening can be exposed to clean dust in the airway with a brush or the like. This structure has a simple configuration, is easy to manufacture and process, and is convenient to use, and has high practicality. Additional aspects and advantages of this utility model will be mentioned in part in the following description, and other parts will become apparent from the following description or will be understood by implementing this utility model.

Brief Description of the Drawings

[0006] To more clearly explain the technical means in this utility model or the prior art, the following will be described with reference to the drawings in a clear and easy-to-understand manner. Obviously, the drawings in the following description are only some embodiments of this utility model, and those skilled in the art can obtain other drawings according to these drawings without creative efforts.

Modes for Carrying Out the Invention

[0007] As shown in FIGS. 1 to 4, this structure includes a heated tobacco device main body 1, a housing 2, a dust cover 3, and a positioning bottom cover 4. As shown in FIGS. 1 and 2, the housing 2 is arranged on the outer periphery of the main body 1, and a ventilation pipe 5 is provided on the main body 1. As shown in FIGS. 3 and 4, a receiving tank 6 is formed at the bottom of the housing 2, and a pipe opening 7 that communicates with the bottom of the ventilation pipe 5 is arranged on the surface of the tank. The dust cover 3 is provided in the receiving tank 6 so as to be slidable left and right, and can cover or expose the pipe opening 7. There is a gap between the peripheral edge of the dust cover 3 and the inner surface of the receiving tank 6, which functions as an air inlet 8 and communicates with the pipe opening 7. The positioning bottom cover 4 fits into the receiving tank 6 and abuts against the right side of the dust cover 3, so that the dust cover 3 completely covers the pipe opening 7, preventing direct dust intrusion from the outside. On the other hand, outside air can flow into the ventilation pipe 5 through the gap between the peripheral edge of the dust cover 3 and the inner surface of the receiving tank 6 to maintain normal operation. When the positioning bottom cover 4 is removed, the dust cover 3 can be slid to the right to expose the pipe opening 7. In this state, the dust inside the ventilation pipe 5 can be easily cleaned using a brush. Furthermore, as shown in FIGS. 3 and 4, a finger hook groove 9 is provided at the bottom of the dust cover 3 to facilitate sliding operation with the fingertips. As shown in FIG. 4, slide rails 10 are formed before and after the dust cover 3, and corresponding slide grooves 11 are formed on the inner surfaces before and after the receiving tank 6, and these are slidably fitted to realize a stable sliding operation of the dust cover 3. The right side surface of the positioning bottom cover 4 shown in FIGS. 3 and 4 has a gap with the inner surface of the receiving tank 6 and is inclined upward to the left, and has a structure that can be easily removed with fingertips.

[0008] As described above, in this utility model, a slidable dust cover 3 is provided at the bottom of the housing 2 of the heated tobacco device. By covering the pipe opening 7, dust prevention of the airway pipe 5 is achieved, or by exposing the pipe opening 7, dust and the like inside the airway pipe 5 can be cleaned with a brush or the like. This structure has a simple configuration, is easy to manufacture and process, and is convenient to use, and has high practicality.
