After use, a new medicine bottle 3 can be replaced for use.

[0022] Referring to Figure 3 , the first cavity 11 is cylindrical, and the first heating member 41 is located in the second cavity 12 and surrounds the first cavity 11; the surrounding arrangement of the first heating member 41 improves the efficiency of heat exchange and increases the heating speed.

[0023] Referring to Figure 3 , the second heating member 42 is arranged on the lower surface of the main body 1; the second heating member 42 can keep the medicine in the negative pressure tank body 2 warm, so that the medicine is warm when contacting the skin, and the absorption efficiency of the medicine is improved.

[0024] Referring to Figure 3 , a ring-shaped convex block 21 is provided on the inner side wall of the negative pressure tank body 2, so as to divide the cavity in the negative pressure tank body 2 into an upper cavity 22 and a lower cavity 23. The second heating member 42 is located in the upper cavity 22; the second heating member 42 uniformly heats the medicine in the upper cavity 22, enabling the temperature felt by the user when contacting the skin to be uniform, and preventing local overheating or cold.

[0025] Referring to Figure 3, the negative pressure tank body 2 is detachably connected to the main body 1. The upper surface of the negative pressure tank body 2 is provided with an annular groove 24. A filter sponge 25 and a sealing ring 26 located above the filter sponge 25 are arranged in the annular groove 24. A first through hole 261 through which the suction port of the negative pressure pump 14 can be exposed is arranged on the sealing ring 26. The arrangement of the sealing ring 26 can prevent air leakage, and the arrangement of the filter sponge 25 can prevent the atomized medicine from being pumped out by the negative pressure pump 14 to the outside world.

[0026] Refer to Figure 2 and Figure 3 , it further includes a pressure relief device 5 located in the second cavity 12. The main body 1 is provided with a second through hole 15 communicating with the inside of the negative pressure tank body 2 so that the outside air can enter the negative pressure tank body 2.

[0029] Refer to Figure 3 , the first cavity 11 is provided with an upper opening 111 communicating with the outside. The upper part of the medicine bottle 3 is provided with an annular protrusion 31 to seal and cover the upper opening 111; during use, since the negative pressure tank body 2 is in a negative pressure state, the first cavity 11 communicating with the negative pressure tank body 2 will also be in a certain negative pressure state, causing the medicine bottle 3 to be subjected to a downward force, and thus being able to seal and cover the upper opening 111.

[0030] Refer to Figure 2 and Figure 3, a circuit board 16 and a pressure sensor 161 disposed on the circuit board 16 are provided in the second cavity 12. A silica gel tube communicating with the inside of the negative pressure tank body 2 is fixed on the surface of the pressure sensor 161. When the pressure reaches the corresponding pressure, the pressure sensor 161 feeds back the detected pressure value to the circuit board 16, and the negative pressure pump 14 stops working. When the pressure is less than the set value, the negative pressure pump 14 works to keep the negative pressure in the negative pressure tank body 2 within the set range, so that users don't have to worry about the negative pressure tank body 2 falling off due to negative pressure fluctuations.
