The beneficial effects of the above technical scheme are that: through the expansion end 232, the piston 22, screwed pipe and knob 21 are to the fixed support of fixed pipe 42, make fixed pipe 42 can support heating element 41 unsettled in the inside of support frame 23, still be provided with fixed establishment 6 at the tip of fixed pipe 42 simultaneously and can be when not using the ear canal to regret the treatment instrument, open fixed establishment 6, make fixed pipe 42 can be through fixed establishment 6 and knob 21 joint, prevent that fixed pipe 42 from accidentally dropping and can't take out in the ear canal regret treatment instrument, the outer wall of fixed pipe 42 still is provided with the external screw thread simultaneously and prevents that fixed pipe 42 from sliding into the inside of ear canal regret the treatment instrument, also can open fixed establishment 6 when using the ear canal regret the treatment instrument, make fixed pipe 42 neither can influence the motion of piston 22 when screwing knob 21, also can not take place the removal along with the rotation of knob 21.

In one embodiment, the fixing mechanism 6 includes a receiving groove 61, a limiting groove 62, a ball shaft 63 and a limiting block 64; accomodate groove 61 with spacing groove 62 all sets up on the lateral wall of fixed pipe 42, just accomodate the both ends of groove 61 respectively with the tip of fixed pipe 42 with the tip intercommunication of spacing groove 62, ball axle 63 sets up accomodate groove 61 with spacing groove 62's intercommunication department, just ball axle 63 is located fixed pipe 42's inside, stopper 64 sets up on the ball axle 63, just stopper 64 is located accomodate the inslot 61.

The working principle of the technical scheme is as follows: fixing mechanism 6 is located the tip of fixed pipe 42, the one end of accomodating groove 61 communicates with the tip of fixed pipe 42, the other end communicates with spacing groove 62, accomodate groove 61 along the axial setting of fixed pipe 42, spacing groove 62 is along the radial setting of fixed pipe 42, when not using fixing mechanism 6, stopper 64 is accomodate in the inside of accomodating groove 61, when using fixing mechanism 6, rotate stopper 64 to spacing groove 62 in through ball axle 63, the length of stopper 64 is greater than the radius of fixed pipe 42, can make things convenient for stopper 64 and knob 21's outer wall joint, and also convenience of customers pulls stopper 64 with the hand, the length and the shape of accomodating groove 61 and spacing groove 62 suit.

The beneficial effects of the above technical scheme are that: through the design of above-mentioned structure, to accomodate groove 61 and spacing groove 62 normal direction setting can directly pull the stopper 64 into and accomodate the groove 61 with the hand when not using fixed establishment 6, when using fixed establishment 6, only need with the stopper 64 pull to the spacing groove 62 in can, because the size shape of spacing groove 62 and accomodating groove 61 suits, and the length of stopper 64 is greater than the radius of fixed pipe 42, make stopper 64 rotate along ball axle 63 no matter how and all have some protrusion spacing groove 62 and accomodate groove 61, the user can directly manually operate through the bulge, need not to accomplish the removal adjustment of stopper 64 with the help of the instrument again.

In one embodiment, the heating member 41 includes: heating the resistance device and the medicine box; the medicine box is connected with the fixed tube 42, the resistance device is arranged in the medicine box, and the resistance device is electrically connected with the temperature control device.

The working principle and the beneficial effects of the technical scheme are as follows: through the design of above-mentioned structure, can directly heat through temperature control device control heating resistance device and toast and carry out temperature regulation when the user needs hot moxibustion, only need fill required medicine in the medicine box when needs carry out medicine moxibustion, can toast the effect in order to reach medicine moxibustion through heating resistance device to the medicine in the medicine box, the residue after toasting can remain and can not fall scald the user on silica gel layer 5 in the medicine box.

In one embodiment, the resistor diameter D of the heating resistor device is selected to satisfy the following formula

Wherein D is electricity in the selected heating resistor deviceThe diameter of the resistor; h is_tA heat transfer coefficient for the selected resistive material; λ is the thermal conductivity of the selected resistor; delta is the winding thickness of the resistor in the heating resistor device; q is the heat conductivity per unit length of the selected resistor material; t is t_bIs a temperature value set by the temperature control device; t is t_aThe current temperature value of the heating resistance device is obtained; omega is the distance between two adjacent resistance wires after winding; n is a radical of_μIs the laminar heat conduction boundary constant of the selected resistor.

The working principle and the beneficial effects of the technical scheme are as follows: the critical temperature t set by the temperature control device can be controlled according to the formula_bAnd the actual temperature t that the theory wants to reach_aAnd the diameter D of the resistance wire required to be selected in the heating resistance device is calculated, so that the problems that the heating temperature is too high due to too thick diameter or the resistance wire is easy to fuse and damage due to too thin diameter and the like are avoided.
