The elastic member 13 may be a spring for assisting the control unit to switch between the first state and the second state.

Further, an atomizing nozzle 14 is installed at one end of the first drain pipe 3 away from the lower chamber 102; and an atomizing spray head 14 is arranged at one end of the second water discharge pipe 4 far away from the upper chamber 101. The fluid is sprayed out through the atomizing spray head 14, and is more effectively attached to the surface and the back of the blade, so that the pest and disease damage is effectively prevented.

Referring to fig. 1, when spraying the pesticide, the liquid enters the main pipe 5, and then enters the lower chamber 102 through the first hole 801, the first connecting channel 805, the second hole 802, and the first auxiliary pipe 6.

Referring to fig. 2, as the pressure in the lower chamber 102 increases, the fluid rises through the first water discharge pipe 3 and is sprayed through the atomizer 14.

Referring to fig. 3, as the pressure in the lower chamber 102 increases, the moving member 2 moves up against the friction force with the cylinder 1, the gravity of the first and second water discharge pipes 3 and 4, and the like, until it contacts the connecting rod 10, and the connecting rod 10 is moved up.

The moving member 2 drives the first water discharge pipe 3 and the second water discharge pipe 4 to ascend, the spraying range is expanded, and the spraying to the surface and the back of the blade can be effectively realized.

Referring to fig. 4, the control unit is in the second state under the action of the moving member 2 and the connecting rod 10. The fluid in the main pipe 5 enters the third hole 803, the second connecting passage 806, the fourth hole 804 into the second sub-pipe 7, and then, into the upper chamber 101.

Referring to fig. 5, as the pressure in the upper chamber 101 increases, the fluid rises through the second water discharge pipe 4 and is sprayed through the atomizer 14.

Referring to fig. 6, as the pressure in the upper chamber 101 increases, the fluid rises through the second water discharge pipe 4 and is sprayed out through the atomizer 14. At the same time, the moving member 2 descends to press the lower chamber 102, and the fluid in the lower chamber 102 is ejected.

The baffle 12 descends to press the connecting rod 10 downwards to drive the first movable piece 9 and the second movable piece 11 to descend, so that the control unit is switched from the second state to the first state.

By last discovery, along with constantly circulating operation, effectual first drain pipe 3, the second drain pipe 4 of letting go up and down constantly, the effectual range that sprays that enlarges can be followed the below and sprayed the blade back, improves the disease and pest prevention effect.

With reference to fig. 1, it can be seen that the spring is extended and can apply an upward force to the link 10, or that the spring is free and applies no force to the link 10.

Referring to fig. 3, the spring is in a horizontal state, and the spring is compressed to store energy. When the connecting rod 10 continues to rise, the spring is stretched, releasing energy, and the control unit can be promoted to be rapidly switched from the first state to the second state.

Similarly, as shown in FIG. 6, it can be seen that the spring is extended and can apply a downward force to the linkage 10, or the spring is free and applies no force to the linkage 10.

When the connecting rod 10 descends, the spring is in a horizontal state again, and the spring is compressed to store energy. As the linkage 10 continues to descend, the spring expands, releasing energy, which may facilitate rapid switching of the control unit from the second state to the first state.

In this embodiment, the housing 8 may be annular and may have no top wall or top wall.

Of course, in another embodiment, the control unit may be as shown in fig. 8, which is different from the present embodiment in that there are no two second movable members 11.

Holes 1001 are provided at both the top and bottom ends of the case 8. The connecting rod 10 is located in the two holes 1001 and can freely lift, and of course, the two holes 1001 need to be sealed to avoid leakage.
