[0033] See also Figure 1-Figure 6 The utility model provides the following technical solutions: a height-adjustable sprayer:

[0034] Embodiment 1: By providing the stirring blade 10, the housing 1 has a mixing function, which can make the liquid mixed better, facilitate the effect of the medicine, and at the same time prevent impurities from precipitating, avoiding the generation of scale, such as Figure 1 and Figure 2 As shown:

[0035] It includes a housing 1 and a pump 2, wherein a base is fixedly connected to the lower surface of the housing 1, and the pump 2 is fixedly connected to the inner wall of the housing 1, and a door panel 5 is hingedly connected to the upper surface of the housing 1, the pump 2 is fixedly connected to the inner wall of the housing 1, and the input end and the output end of the pump 2 are fixedly connected to a water pipe 3, and a hose 4 is fixedly connected to the surface of the water pipe 3 at the output end of the pump 2;

[0036] A height-adjustable sprayer, further comprising:

[0037] The motor 6 is bolted to the outer wall of the housing 1, and the output end of the motor 6 is fixedly connected to the connecting shaft 7, and the inner wall of the housing 1 is fixedly connected to the limit block 11, and the vertical rod 9 is rotatably arranged inside the limit block 11, and the surface of the vertical rod 9 is fixedly connected to the stirring blade 10;

[0038] The spray plate 13 is movably arranged on the surface of the housing 1, and a nozzle 14 is opened on the surface of the spray plate 13. The upper surface of the vertical rod 9 and the surface of the connecting shaft 7 are fixedly connected with the bevel gear 8, and the vertical rod 9 passes through the inside of the limit block 11, and the surface of the vertical rod 9 is convex.

[0039] During operation, the pump 2 is started to feed the spray plate 13 and the nozzle 14 through the water pipe 3 and the hose 4, so that the liquid is sprayed. At the same time, the motor 6 is also started, and the motor 6 drives the connecting shaft 7 to rotate. At this time, the connecting shaft 7 drives the vertical rod 9 and the stirring blade 10 to rotate under the action of the bevel gear 8. When the stirring blade 10 rotates, the liquid can be mixed better, which is convenient for the medicine to take effect. At the same time, impurities are not precipitated, and the formation of scale is avoided. When the vertical rod 9 rotates, the raised position on the surface of the vertical rod 9 makes the vertical rod 9 rotate more stably inside the limit block 11.

[0040] Embodiment 2: Different from Embodiment 1, by providing the cam 17 and the auxiliary block 18, the height area of ​​the spray plate 13 and the nozzle 14 can be adjusted and changed during operation, thereby expanding the scope of use, such as Figure 3-Figure 6 As shown:

[0042] When the connecting shaft 7 rotates, the connecting shaft 7 will drive the cam 17 to rotate synchronously. When the cam 17 rotates to contact with the auxiliary block 18, the auxiliary block 18 is pushed. At this time, the auxiliary block 18, the spray plate 13 and the fixed block 15 rotate around the limiting rod 12. When the cam 17 rotates to no longer contact with the auxiliary block 18, the auxiliary block 18 and the spray plate 13 return to their original positions under the action of their own gravity. The above process is repeated. The spray plate 13 and the nozzle 14 perform reciprocating circular motion, thereby changing the height of the nozzle 14, making the nozzle 14 spray over a wider range and improving work efficiency.

[0043] Embodiment 3: Different from Embodiment 2, the balls 16 are provided to make the fixed block 15 more stable when rotating. Figure 3 As shown:

[0045] Initially, the auxiliary block 18 fits against the outer wall of the shell 1, and the shell 1 limits the rotation angle of the auxiliary block 18, so that the cam 17 can cooperate with the auxiliary block 18 normally every time, thereby improving stability. When the fixed block 15 rotates, the ball 16 makes the fixed block 15 only rotate around the limit rod 12 and does not move in the horizontal direction. At the same time, the ball 16 makes the fixed block 15 rotate more smoothly.

[0046] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
