[0027] The above protection structure 4 includes: a fixing block 41, a rotating shaft 42, a connecting block 43, a protective cover 44, a fixing sleeve 45, an auxiliary spring 46, a clamping block 47, a supporting block 48, and a clamping groove 49. A fixing block 41 is fixedly connected to the outer wall of the nozzle 2, a rotating shaft 42 penetrates through the outer wall of the fixing block 41, the fixing block 41 plays a supporting role for the rotating shaft 42, the rotating shaft 42 is rotatably connected to the fixing block 41 on the outer wall, a connecting block 43 is fixedly connected to the outer wall of the rotating shaft 42, the connecting block 43 will rotate around the rotating shaft 42 as the center of the circle as the rotating shaft 42 rotates, one end of the connecting block 43 away from the rotating shaft 42 is fixedly connected to a protective cover 44, the protective cover 44 will perform a circular motion around the rotating shaft 42 as the connecting block 43 rotates, and thus the nozzle 2 is protected by the protective cover 44. A fixing sleeve 45 is fixedly connected to the outer wall of the protective cover 44, the fixing sleeve 45 will perform a circular motion as the protective cover 44 performs a circular motion, the protective cover 44 plays a fixing role for the fixing sleeve 45, an auxiliary spring 46 is fixedly connected to the inner wall of the fixing sleeve 45, the fixing sleeve 45 plays a fixing role for the auxiliary spring 46, one end of the auxiliary spring 46 away from the fixing sleeve 45 is fixedly connected to a clamping block 47, the clamping block 47 will move in a direction away from the auxiliary spring 46 by the elastic force of the auxiliary spring 46, a supporting block 48 is fixedly connected to the outer wall of the nozzle 2, the nozzle 2 plays a fixing role for the supporting block 48, a clamping groove 49 is formed in the outer wall of the supporting block 48, and the inner wall of the clamping groove 49 is in contact with the clamping block 47.

[0028] The above-mentioned cleaning structure 5 includes: an auxiliary rod 51, a cleaning brush 52, a return spring 53, a support plate 54, and a handle 55. The outer wall of the protective cover 44 is penetrated by the auxiliary rod 51. There are multiple groups of the auxiliary rods 51, and the number of the auxiliary rods 51 is the same as the number of the spray holes of the nozzle 2. Moreover, the size of the auxiliary rod 51 is smaller than the size of the spray hole of the nozzle 2. The outer wall of the auxiliary rod 51 is slidably connected to the protective cover 44. A return spring 53 is fixedly connected to the outer wall of the protective cover 44, and the protective cover 44 plays a fixing role for the return spring 53. The number of the return springs 53 is the same as the number of the auxiliary rods 51. The end of the return spring 53 far from the protective cover 44 is fixedly connected to the support plate 54, and the return springs 53 are all fixedly connected to the support plate 54. Moreover, the return spring 53 will push the support plate 54 to move in a direction away from the return spring 53 through its own elastic force. A cleaning brush 52 is fixedly connected to the outer wall of the auxiliary rod 51, and the cleaning brush 52 will move along with the movement of the auxiliary rod 51. Furthermore, the scale in the nozzle 2 is cleaned by the cleaning brush 52. The outer wall of the protective cover 44 is slidably connected to the support plate 54, and a handle 55 is fixedly connected to the outer wall of the support plate 54. The handle 55 can drive the support plate 54 to move.

[0029] Working principle: By rotating the rotating shaft 42, at this time, the connecting block 43 will rotate around the rotating shaft 42 with the rotation of the rotating shaft 42. At this time, the protective cover 44 will perform a circular motion around the rotating shaft 42 with the rotation of the connecting block 43, so that the protective cover 44 covers the nozzle 2. When the protective cover 44 performs a circular motion, at this time, the fixed sleeve 45 will perform a circular motion with the circular motion of the protective cover 44. At this time, the clamping block 47 will move with the movement of the fixed sleeve 45. At this time, the inclined surface of the clamping block 47 will contact the outer wall of the nozzle 2. Furthermore, due to the blockage of the outer wall of the nozzle 2, the clamping block 47 will retract into the fixed sleeve 45. When the protective cover 44 is parallel to the nozzle 2, at this time, the clamping block 47 will be directly below the clamping groove 49. At this time, the clamping block 47 will be inserted into the clamping groove 49 due to the elastic force of the auxiliary spring 46, so as to play a fixing role for the protective cover 44, thus avoiding the nozzle 2 being exposed outside when the main body 1 is not in use and being easily contaminated with dust and blocked.

[0030] At the same time, when the protective cover 44 covers the nozzle 2, at this time, the auxiliary rod 51 will be parallel to the spray hole of the nozzle 2. At this time, the handle 55 can be moved back and forth. At this time, the support plate 54 will move with the movement of the handle 55. Furthermore, the support plate 54 drives the auxiliary rod 51 to move. At this time, the cleaning brush 52 will move with the movement of the auxiliary rod 51. Furthermore, the scale in the spray hole of the nozzle 2 is cleaned by the cleaning brush 52.

[0031] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit and idea of the present utility model are within the protection scope of the present utility model.
