[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present utility model belong to the protection scope of the present utility model.
[0020] The purpose of the present utility model is to provide a spraying device to solve the problems existing in the above-mentioned prior art and effectively expand the spraying range.
[0021] In order to make the above-mentioned objects, features and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the drawings and specific embodiments.
[0022] As shown Figures 1-2 in the figure, the present utility model provides a spraying device, which includes a shunt pipe 1. The first end of the shunt pipe 1 has a buffer chamber 2. A liquid inlet and a liquid outlet are provided on the side wall of the buffer chamber 2. The second end of the shunt pipe 1 has a plurality of shunt channels 3. The first end of each shunt channel 3 is connected to and communicates with the liquid outlet. The second end of each shunt channel 3 extends away from the buffer chamber 2. The second end of each shunt channel 3 extends away from the center line of the shunt pipe 1. A nozzle 4 is fixedly provided at the second end of each shunt channel 3. The nozzle 4 can communicate the shunt channel 3 with the outside.
[0023] For the spraying device provided by the present utility model, by providing the buffer chamber 2 to buffer the liquid, and by providing that the second end of each shunt channel 3 extends away from the buffer chamber 2 and the second end of each shunt channel 3 extends away from the center line of the shunt pipe 1, the liquid is shunted, so that the liquid flows in each shunt channel 3 in a direction away from the center line of the shunt pipe 1. Finally, the liquid is sprayed from the nozzles 4 provided at the second ends of each shunt channel 3 to the target area, and the spraying range can be effectively expanded.
[0024] Furthermore, the spraying device provided by the present utility model further includes a liquid conveying pipe 5. One end of the liquid conveying pipe 5 is connected to and communicates with the liquid inlet, and the liquid conveying pipe 5 is used to supply liquid to the buffer chamber 2 to ensure that there is sufficient liquid in the buffer chamber 2.
[0025] Furthermore, the spraying device provided by the present utility model further includes a buffer housing 6. The buffer housing 6 is used to buffer the liquid. The buffer housing 6 is connected to and communicates with the end of the liquid conveying pipe 5 far from the liquid inlet. The buffer housing 6 is connected to a container for holding the liquid to continuously supply liquid to the liquid conveying pipe 5.
[0026] As a relatively preferred implementation manner of this embodiment, the first end of each shunt channel 3 is smoothly connected to the liquid outlet, one end of the liquid conveying pipe 5 is smoothly connected to the liquid inlet, and the buffer housing 6 is smoothly connected to the end of the liquid conveying pipe 5 far from the liquid inlet, so as to reduce the flow resistance of the liquid.
[0027] Furthermore, the spraying device provided by the present utility model further includes a protective cover 7. The protective cover 7 is fixedly sleeved outside the shunt pipe 1, the liquid conveying pipe 5 and the buffer housing 6. The diameter of the protective cover 7 gradually increases from the buffer housing 6 towards the shunt pipe 1 direction, which can not only effectively protect the shunt pipe 1, the liquid conveying pipe 5 and the buffer housing 6, but also avoid hindering the liquid spraying of the nozzles 4.
[0028] As a relatively preferred implementation manner of this embodiment, each shunt channel 3 is symmetric about the center line of the shunt pipe 1, with a simple structure and convenient use.
[0029] As a relatively preferred implementation manner of this embodiment, each diversion channel 3 is uniformly arranged around the central axis of the diversion pipe 1, which is beneficial to realizing the uniform spraying of the liquid. In this embodiment, the number of the diversion channels 3 is four.
[0030] As a relatively preferred implementation manner of this embodiment, a plurality of water spraying holes 8 are formed in the nozzle 4. The water spraying holes 8 gradually contract first and then gradually expand from the direction close to the buffer cavity 2 to the direction away from the buffer cavity 2, which is convenient for forming a conical radiation spray with high pressure and large area, so as to achieve the spraying effect of large area and high pressure.
[0031] Specific examples are applied in the present utility model to expound the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
