 The structure in which the tobacco evaporators are in different states of use in the present embodiment will be specifically described below.

Figure 4 is a partial structural exploded view of the tobacco evaporator according to the first embodiment of the present invention in a first state, in order to more clearly see the internal structure of the tobacco evaporator in the first state, Figure 4 The cover housing 110 is disassembled from other structures. The first state in which the tobacco evaporator is located is a state in which the upper cover assembly 10 and the lower cover assembly 20 are joined and fixed together. In this state, the first positioning magnet 71 is opposed to the second positioning magnet 72 and attracts each other; The 223 cooperates with the first portion 41 of the chute 40, and the upper cover assembly 10 and the lower cover assembly 20 are stably joined together. In this state, the tobacco evaporator can be used normally.

Fig. 5 is a partially exploded perspective view showing the tobacco evaporator of the first embodiment of the invention in a second state. Similarly, in the figure, the upper cover casing 110 is decomposed from other structures. When the user needs to replace the tobacco sheet after the tobacco sheet 4 is used, the close joint between the upper lid assembly 10 and the lower lid assembly 20 needs to be released. First, the user overcomes the fixed ends of the upper lid assembly 10 and the lower lid assembly 20 The attraction between the positioning magnet 71 and the second positioning magnet 72 rotates the upper cover assembly 10 (or the lower cover assembly 20) in a certain direction (for example, clockwise direction), and the upper cover assembly 10 is opposite to the lower cover assembly 20 Moving, the second rotating magnet rotates relative to the first rotating magnet, the cylindrical portion of the positioning nail 223 is inserted into the sliding slot 40, and the nail cap portion is located above the sliding slot 40, so that the entire positioning nail 223 approaches the second portion 42 in the sliding slot 40. The sliding direction of the upper cover assembly 10 and the lower cover assembly 20 are not easily separated during relative rotation, and the first receiving cavity 51 is gradually exposed. For example, in FIG. 5, the upper cover assembly 10 (or the lower cover assembly 20) is rotated to the lower side. The cover assembly 20 (or the upper cover assembly 10) has an angle of 60°.

Fig. 6 is a partially exploded perspective view showing the tobacco evaporator of the first embodiment of the invention in a third state. Similarly, in the figure, the upper cover casing 110 is decomposed from other structures. In the figure, the upper cover assembly 10 (or the lower cover assembly 20) is rotated to a defined maximum rotational position, that is, the upper cover assembly 10 (or the lower cover assembly 20) is rotated to and the lower cover assembly 20 (or the upper cover assembly 10) The angle is 90°. In this state, the first accommodating chamber 51 is completely exposed, and the user can turn the tobacco evaporator, pour out the used tobacco sheet, reinstall the new tobacco sheet, and then along and remove the upper lid assembly 10 and the lower lid assembly 20. The upper cover assembly 10 (or the lower cover assembly 20) is rotated in a direction opposite to the rotation direction (for example, counterclockwise direction), the upper cover assembly 10 and the lower cover assembly 20 are relatively moved, and the second rotary magnet is rotated relative to the first rotary magnet. The positioning pin 223 slides in the direction away from the second portion 42 in the sliding groove 40, and finally the first positioning magnet 71 and the second positioning magnet 72 are opposite each other, and the upper cover assembly 10 and the lower cover assembly 20 are re-tightly fixed together, visible The upper cover assembly 10 and the lower cover assembly 20 can achieve a simple and convenient effect of the installation and removal operations of the tobacco sheet by the rotating mechanism.

When the tobacco evaporator needs to be cleaned, the positioning pin 223 is located in the second portion 42 of the chute 40 when the upper cap assembly 10 (or the lower cap assembly 20) is rotated to the defined maximum rotational position in the state shown in FIG. Since the width of the second portion 42 is larger than the size of the nail of the positioning pin 223, the positioning pin 223 can pass through the second portion 42 of the chute 40, and at the same time, the rotational engagement of the first rotating magnet and the second rotating magnet Release, the user only needs to overcome the mutual attraction between the first rotating magnet and the second rotating magnet to completely separate the upper cover assembly 10 and the lower cover assembly 20, and the user can clean the tobacco evaporator.
