The extension direction of the longitudinal groove 461 is the axial direction of the liquid storage shell 41, and the circumferential groove 462 extends along the circumferential surface of the liquid storage shell 41. The protrusion 3221 can be inserted into the longitudinal groove 461. By rotating the liquid storage shell 41, the protrusion 3221 is rotated to the end of the circumferential groove 462, so that the position of the liquid storage shell 41 and the fixing member 32 can be limited. It should be noted that the names of the large-diameter ring 412 and the small-diameter ring 413 are only used to distinguish the parts, and the size relationship between the two is not limited thereto.

[0049] Furthermore, a locking protrusion 463 is fixed in the circumferential groove 462, and the locking protrusion 463 can be locked in the protrusion 3221. Both ends of the protrusion 3221 are provided with inclined surfaces 3222, so that when the protrusion 3221 is rotated into the end of the circumferential groove 462, it is not easy to fall off when it is rotated without force. The inclined surface 3222 can facilitate the user to smoothly rotate the protrusion 3221 into or out of the circumferential groove 462, so that the user can quickly assemble or separate the liquid storage shell 41 from the fixing part 32.

[0050] As an embodiment, the sealing cover 45 is detachably connected to the liquid storage shell 41. Specifically, the sealing cover 45 is bolted to the liquid storage shell 41, and the sealing cover 45 can be removed, so that the user can remove the liquid storage tank 42 for replacement, thereby adding liquid or replacing other types of liquid.

[0051] As an embodiment, a first annular groove 451 is defined on one side of the sealing cover 45. A first sealing ring 4511 is fixed in the first annular groove 451. One end of the liquid storage tank 42 can be inserted into the first annular groove 451 and pressed against the first sealing ring 4511, allowing the sealing cover 45 to fully seal the end of the liquid storage tank 42 and maintain a sealed environment within the liquid storage tank 42. A second annular groove 4111 is defined on the outer circumference of the first discharge pipe 411. A second sealing ring 4112 is fixed in the second annular groove 4111. The second sealing ring 4112 presses against the inner side of the lower pressure ring 323 to prevent liquid leakage.

[0052] As an embodiment, a sealing rubber ring 6 is provided on the inner side of the first discharge pipe 411, and the sealing rubber ring 6 includes a first ring portion 61 and a second ring portion 62. The second ring portion 62 is located on the inner periphery of the first ring portion 61, and the outer periphery of the first ring portion 61 can be pressed against the inner periphery of the first discharge pipe 411.

The temperature control component 4522 is connected to the temperature-controlled heating conductive plate 4521, and the heating device 43 is connected to the temperature-controlled heating conductive plate 4521. When the heating temperature is too high, the temperature control component 4522 can prevent the heating device 43 from continuing to heat, thereby keeping the liquid heated to a stable temperature. It should be noted that the conductive plate that controls heating and provides overheating protection is a prior art, and its specific circuit structure will not be described in detail in this application.

[0054] The implementation principle of the present invention is as follows: when working, the heating device 43 can be located outside the liquid storage tank 42 to generate heat, heating the liquid in the liquid storage tank 42 to a certain temperature, and the piston 44 can move toward the discharge cylinder 2, thereby pushing the heated liquid in the liquid storage tank 42 to be discharged through the first discharge pipe 411 and the second discharge pipe 421. The discharged liquid is discharged from the drainage slit 3124 in the silicone plug 3123 into the channel 23 and discharged from the second end 22 under the promotion of continued pressure by the piston 44, which can achieve the heating and spraying of the liquid, so that the user can have a better use experience.
