According to the utility model discloses sprinkler 100 is through locating sealing member 3 between installation shell 2 and sprinkler 100 for sealing member 3 can block the solution that sprays in the module 4 and contact with driving motor 1, thereby leads to driving motor 1 to damage. The first waterproof positioning piece 5 is arranged between the sealing piece 3 and the installation shell 2, so that on one hand, the first waterproof positioning piece 5 can play a positioning role, the installation shell 2 is conveniently connected with the sealing piece 3, the assembly efficiency of the spraying device 100 is improved, the operation is simple, and the practicability is high; on the other hand, first waterproof setting element 5 plays waterproof sealing effect for driving motor 1 is destroyed in the solution of sealing member 3 lower extreme can not pass first waterproof setting element 5 and get into installation cavity 21, thereby guarantees that driving motor 1 can not break short circuit or corrode etc. improves the security, and then can improve sprinkler 100's life, thereby improves and sprays efficiency.

In some embodiments of the present invention, the first waterproof positioning member 5 includes: a first seal projection 51 and a first seal groove 52. Specifically, a first seal projection 51 is provided on one of the mounting housing 2 and the seal member 3 and is disposed around the circumference of the first shaft hole 211, a first seal groove 52 is formed on the other of the mounting housing 2 and the seal member 3, and the first seal projection 51 is adapted to be fitted in the first seal groove 52.

In one example, a first sealing projection 51 is provided on the mounting housing 2 and a first sealing groove 52 is provided on the side of the sealing element 3 facing the mounting housing 2. In another example, the first sealing projection 51 is provided on the sealing element 3, and the first sealing groove 52 is provided on the side of the mounting housing 2 facing the sealing element 3.

In the two examples, the first sealing protrusion 51 is opposite to the first sealing groove 52, the shape of the first sealing protrusion 51 is the same as that of the first sealing groove 52, and the width of the first sealing protrusion 51 is smaller than that of the first sealing groove 52, so that the first sealing protrusion 51 can be more conveniently fitted in the first sealing groove 52. In addition, by arranging the first sealing protrusion 51 around the circumferential direction of the first shaft hole 211, after the first sealing protrusion 51 is fitted in the first sealing groove 52, the circumferential direction of the first shaft hole 211 can be sealed, so that the solution cannot pass through the first sealing protrusion 51 and the first sealing groove 52 and enter the first shaft hole 211, and the output shaft of the driving motor 1 can be protected. Meanwhile, after the first sealing protrusion 51 is matched in the first sealing groove 52, the sealing element 3 and the mounting shell 2 can be stably matched together, and the partial area of the mounting shell 2 and the sealing element 3 is prevented from being not matched together, so that the driving motor 1 is influenced to drive the connecting shaft 41 to rotate, and the centrifugal spraying disc 42 cannot centrifugally spray out the solution well.

Optionally, the spraying device 100 further includes a plurality of connectors 6, the plurality of connectors 6 pass through the sealing member 3 and then are connected to the mounting case 2, wherein a plurality of first connection holes 32 are formed in the sealing member 3, and the plurality of connectors 6 are disposed in one-to-one correspondence to the plurality of first connection holes 32, for example, as shown in fig. 5, a plurality of through first connection holes 32 may be formed in the sealing member 3, and the plurality of connectors 6 pass through the corresponding first connection holes 32, so that the sealing member 3 can be stably connected to the mounting case 2, and the sealing member 3 is prevented from being separated from the mounting case 2 when the spraying device 100 performs a spraying operation. Here, it can be understood that the first coupling holes 32 may be formed on the sealing member 3 at regular intervals, so that the force applied to the sealing member 3 is uniform after the coupling member 6 passes through the first coupling holes 32, thereby allowing the sealing member 3 to be coupled with the mounting case 2 more stably.

In the above embodiment, be equipped with a plurality of waterproof bosss 22 on the diapire of installation shell 2, form the first blind hole of opening towards first connecting hole 32 on the waterproof boss 22, connecting piece 6 cooperates in first blind hole, every waterproof boss 22 cooperation is in the first connecting hole 32 that corresponds, that is to say, waterproof boss 22 is relative from top to bottom with first connecting hole 32, and the outer peripheral dimension of waterproof boss 22 is less than the internal diameter dimension of first connecting hole 32 to make waterproof boss 22 can cooperate in first connecting hole 32.

It will be appreciated that if solution leaks out of the junction between the seal 3 and the baffle 8, the amount of solution in the baffle 8 is reduced, which results in a reduced amount of solution being sprayed from the centrifugal spray disk 42, which in turn reduces the efficiency of the spray. Meanwhile, the solution leaks out from the junction between the sealing member 3 and the flow guide member 8, so that the solution is occupied outside the spraying device 100, and when the solution is a medicine, the personnel touching the spraying device 100 are easily injured, namely, the spraying device 100 is caused to threaten health.
