The adjusting ring is linked by the knob rotation, and the adjusting ring is linked by the heating element bracket, and the heating element bracket moves up and down in the guide groove, which can change the heating range of the heating element acting on the core rod, thereby realizing the adjustment of the volatilization speed.

[0004] However, the above patent has the following defects:

[0005] (1) Combined with the attached Figure 1 It can be seen that the knob is arranged on the outer peripheral surface of the adjustment ring, and is actually located on the side of the shell of the heater, which has a certain impact on the aesthetics of the heater and is prone to misoperation;

[0006] (2) There is a lack of effective indication of the rotation position of the adjustment ring or the up and down movement position of the heating element bracket, and the user cannot intuitively know what adjustment state the heater is currently in;

[0007] (3) The volatilized gas may flow along the gap between the shell and the heating element bracket, affecting the diffusion effect of the volatilized gas to the outside and easily affecting the circuit part of the heater;

During assembly, the heating element bracket is inserted into the adjustment ring, and the protrusion is inserted along the inclined groove from the outside and connected and fixed to the heating element bracket. The operation is relatively cumbersome and also increases the production cost. Summary of the invention

[0011] Furthermore, the upper end of the chamber extends downward to form a first pipe connected to the first hole, and the upper end of the heating element extends upward to form a second pipe connected to the third hole. The first pipe and the second pipe form a movable sleeve. When the heating element moves up and down, the second pipe also moves up and down, so that the pipe formed by the first pipe and the second pipe can produce a telescopic effect as a whole, and can change its length to adapt to the movement of the heating element. The pipe with this structure is simple in structure and convenient to install.

The shell 1 includes a first hole 11 connected to the upper end of the chamber 10 and a second hole 12 connected to the lower end of the chamber 10. The first hole 11 is for the volatilized gas to diffuse upward and to the outside of the shell 1, and the second hole 12 is used to cooperate with the core rod of the liquid storage bottle. The core rod can be inserted into the chamber 10 along the second hole 12. A heating element 2 that can be controlled to move up and down is provided in the chamber 10. The heating element 2 includes a third hole 21, and the third hole 21 is used to cooperate with the core rod of the liquid storage bottle. The heating range of the heating element 2 on the core rod can be changed by adjusting the up and down position of the heating element 2, thereby realizing the adjustment of the volatilization speed. A pipe that is retractable based on the up and down movement of the heating element 2 is connected between the first hole 11 of the shell 1 and the third hole 21 of the heating element 2, and the pipe is used to guide the gas generated by volatilization toward the outside of the chamber 10.

[0027] like Figure 3 , 7 As shown in FIG. 9 , the upper end of the chamber 10 extends downward to form a first pipe 31 connected to the first hole 11, and the upper end of the heating element 2 extends upward to form a second pipe 32 connected to the third hole 21. The first pipe 31 and the second pipe 32 form a movable sleeve fit. When the heating element 2 moves up and down, the second pipe 32 will also move up and down, so that the pipe composed of the first pipe 31 and the second pipe 32 can produce a telescopic effect as a whole, and can change its length to adapt to the movement of the heating element 2. The pipe with this structure is simple in structure and convenient to install.

[0028] The housing 1 includes a base 13 and a knob assembly. The knob assembly and the base 13 are rotatably connected and matched. The knob assembly includes a knob 14 and an adjustment ring 15 arranged at the lower end of the knob 14. The knob 14 includes a first part and a second part. The second part is an annular flange 141 integrally connected to the upper end of the adjustment ring 15. The first part is a cover plate 142 fixed at the inner hole of the annular flange 141. The structures of the first part and the second part are respectively as follows: Figure 6 , 7 As shown, the upper end of the base 13 is provided with a notch, the knob 14 is arranged above the base 13, the knob 14 constitutes the top wall of the chamber 10, the notch of the base 13 constitutes the bottom wall and the side wall of the chamber 10, the first hole 11 is arranged on the cover plate 142 of the knob 14, the second hole 12 is arranged at the lower part of the notch of the base 13, the adjustment ring 15 is inserted and arranged in the notch and sleeved around the heating element 2, the adjustment ring 15 and the heating element 2 form a linkage, so that the adjustment ring 15 can drive the heating element 2 to move up and down when it rotates. The use of this knob 14 structure is not only simple in structure and easy to install, but also makes the rotation operation more labor-saving and convenient, and is not prone to misoperation, and also makes the overall appearance of the vaporizer more neat and beautiful.
