[0031] The fuselage 10 plays a supporting role, and a control module is installed inside the fuselage 10, the support column 11 and the bottom plate 12 play a supporting role, the water pump 13 provides power, the hose 14 connects the water pump 13 and the spray head, the opening 15 plays a limiting role, and the medicine cartridge 16 is used to contain the medicine liquid.

[0032] The quick assembly includes a support plate 20, a first groove 21, a through hole 24, a spring column 25, a T-shaped plunger 26, a second rubber pad 27, a third groove 28 and an L-shaped elbow 29. The support plate 20 is fixed to one end of the bottom plate 12 and is located directly below the opening 15. The first groove 21 is provided in the middle of one end of the support plate 20. The L-shaped elbow 29 is clamped in the first groove 21. The through hole 24 is provided in the inner bottom surface of the cartridge 16. The spring column 25 is embedded in the inner bottom surface of the cartridge 16 and is located on the side of the through hole 24. The lower surface of the top end of the T-shaped plunger 26 is fixed to the movable end of the spring column 25. The second rubber pad 27 is sleeved on the top end of the T-shaped plunger 26. The third groove 28 is provided at the lower end of the T-shaped plunger 26.

[0033] The quick assembly also includes a first rubber pad 22 and a second groove 23. The first rubber pad 22 is fixed on the support plate 20 and sleeved on the upper section of the L-shaped elbow 29.

[0034] The first rubber pad 22 is movably connected in the second groove 23, and the second rubber pad 27 is movably connected to the inner bottom surface of the cartridge 16;

[0035] The support plate 20 plays a supporting role, the first groove 21 plays a limiting role, the first rubber pad 22 plays a sealing role, the second groove 23 plays a limiting role, the through hole 24 facilitates the circulation of the medicine, the spring column 25 has a contraction function, the T-type plunger 26 plays a sealing role, the second rubber pad 27 plays a sealing role, the third groove 28 facilitates the flow of the medicine, and the L-shaped elbow 29 plays a connecting role.

[0036] Working principle:

[0037] When it is necessary to remove the cartridge 16, it is only necessary to empty the liquid medicine in the cartridge 16, hold the cartridge 16 by hand, and lift the cartridge 16 upward along the opening 15. As the cartridge 16 moves upward, the first rubber pad 22 disengages from the second groove 23, and the T-shaped plunger 26 disengages from the L-shaped elbow 29. The spring column 25 contracts and drives the T-shaped plunger 26 to move downward, so that the T-shaped plunger 26 moves downward along the through hole 24, and the third groove 28 sinks into the through hole 24 until the second rubber pad 27 at the upper end of the T-shaped plunger 26 fits against the inner bottom surface of the cartridge 16. When the cartridge 16 is placed in the opening 15, the L-shaped elbow 29 is inserted into the through hole 24, and the L-shaped elbow 29 lifts the T-shaped plunger 26 to expose the third groove 28 in the cartridge 16. The liquid medicine flows from the third groove 28 into the L-shaped elbow 29, and then flows from the hose 14 to the spray head through the water pump 13.

[0038] This step can quickly separate the cartridge 16 from the body 10, which is convenient to operate and saves time and effort.

[0039] See also Figure 5 This embodiment is based on the above embodiment and further includes:

[0041] The positioning assembly further includes a positioning wheel 32, which is rotatably connected between the two fixing plates 31, and the three sides of the cartridge 16 are movably connected to the positioning wheel 32;

[0042] The supporting block 30 and the fixing plate 31 play a supporting role, and the positioning wheel 32 plays a positioning role.

[0043] Working principle:

[0044] When the cartridge 16 needs to be installed, the cartridge 16 is held by hand, the lower end is aligned with the opening 15 and lowered, and the three lower side edges of the cartridge 16 are fitted on the positioning wheel 32 and continue to move downward, so that the positioning wheel 32 rotates around the fixing plate 31 until the second groove 23 under the cartridge 16 is stuck on the first rubber pad 22 and the L-shaped elbow 29 is inserted into the through hole 24.

[0045] This step is helpful to quickly place the cartridge 16 in the correct position.
