[0002] According to the search, the sweeper water spraying system with announcement No.CN207760781U, by front water spraying structure, when cleaning dust, by spraying water mist, let dust settle, to improve the cleaning ability to dust.

[0003] The deficiencies of the sweeper water spraying system in the above-mentioned comparative example are: the spray head of the water spraying structure works in a harsh environment, and it will most likely directly contact dust and ground garbage. During the cleaning process of the sweeper, debris, hair, dust and other garbage on the ground are easily wrapped by the water flow to the spray head, and then enter the inside of the spray head. Once the spray head is blocked by these sundries, the water flow cannot be normally sprayed, and the water spraying and dust settling function will be invalid. This not only greatly reduces the suppression ability of the sweeper to the dust on the ground during the cleaning process, but also makes it difficult to moisten and soften some sticky stains on the ground, so that the subsequent cleaning work cannot be completed completely, which seriously affects the overall cleaning effect of the sweeper and the user experience.

DETAILED DESCRIPTION

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 6 As shown, this utility model provides a sweeper water spraying system, including a sweeper body 1, a cleaning head 2 located at the bottom of the sweeper body 1, and an anti-clogging structure 3 located above and inside the sweeper body 1.

[0022] The anti-clogging structure 3 includes an air pump 31 and a water pump 32 installed in the sweeper body 1, and an annular water pipe 33 connected to the output end of the water pump 32. An annular air pipe 34 is provided above the annular water pipe 33. A connecting pipe 35 is provided between the annular air pipe 34 and the annular water pipe 33, and a one-way valve is provided inside the connecting pipe 35.

[0023] The above solution effectively solves the problem of easy clogging of the nozzle 36 through the design of the anti-clogging structure 3. The filter screen 37 can initially intercept large particles of impurities, reducing the risk of clogging. When the air pump 31 is working, it generates powerful compressed air, which is rapidly transmitted along the output pipe 311 and then evenly enters the annular air pipe 34 through the distribution pipe 38. Since the annular air pipe 34 and the annular water pipe 33 are connected by the connecting pipe 35, the compressed air will enter the annular water pipe 33 along the connecting pipe 35. The one-way valve installed inside the connecting pipe 35 plays a role in... It plays a crucial role by allowing compressed air to flow only from the annular air pipe 34 to the annular water pipe 33, effectively preventing water from flowing back into the annular air pipe 34. When the water pipe nozzle 36 becomes blocked, the compressed air continuously generated by the air pump 31 accumulates in the annular water pipe 33, forming a powerful pulse impact force. This impact force can instantly break through the blockage, restoring the blocked pipe and nozzle 36 to unobstructed flow, ensuring that the water can spray out normally, maintaining the stable operation of the sweeper's water spraying and dust suppression function, and allowing the sweeper to maintain a high cleaning efficiency throughout the cleaning process.

[0024] like Figures 1 to 6 As shown, four nozzles 36 are installed at the top of the annular water pipe 33, which are equidistant from each other and connected to the annular water pipe 33. A filter screen 37 is installed inside the nozzle 36. There are also four connecting pipes 35, all located directly above the nozzles 36. The output end of the air pump 31 is connected to the output pipe 311, and a distribution pipe 38 connected to the top of the output pipe 311 is installed.

[0025] Adopting the above scheme: the four spray heads 36 distributed equidistantly on the top of the annular water pipe 33 can evenly cover the ground with water flow, avoid dead cleaning angle, and improve the cleaning effect, the communicating pipe 35 corresponding to each spray head 36 is arranged above the spray head 36, so that compressed air can efficiently act on each spray head 36, when the spray head 36 is blocked, each spray head 36 can be dredged at the same time, so that all spray heads 36 can work normally and maintain the effect of uniform water spraying.

[0026] As shown in Figures 1 to 6 The distribution pipe 38 is installed on the inner wall of the annular air pipe 34 and communicates with the annular air pipe 34, the top surface of the sweeper body 1 is provided with a threaded hole, and the inner wall of the threaded hole is threadedly connected with a water storage barrel 39, and the bottom of the water storage barrel 39 is communicated with a drain pipe 391.

[0027] Adopting the above scheme: the water storage barrel 39 is connected with the sweeper body 1 through threads, and is very convenient to install and disassemble, so that the water storage barrel 39 can be easily taken out for water filling, cleaning and other operations, thereby reducing the difficulty of use and maintenance and improving the use experience.

[0028] As shown in Figures 1 to 6 The bottom of the drain pipe 391 communicates with the input end of the water pump 32, and the water pump 32 transmits the water in the water storage barrel 39 to the annular water pipe 33, thereby providing water source for the spray head 36.

[0029] Adopting the above scheme: the distribution pipe 38 is installed on the inner wall of the annular air pipe 34 and communicates with the annular air pipe 34, so that the compressed air generated by the air pump 31 can uniformly enter the annular air pipe 34, and then accurately act on each spray head 36 through the communicating pipe 35, when a certain spray head 36 is blocked, sufficient pulse impact force can be obtained in time for dredging, so that the whole water spraying system can stably run, and in order to adapt to the pulse force, the pipes mentioned in the application, such as the annular air pipe 34, are all high-strength polyethylene pipes.

[0030] The working principle of the utility model is:

[0031] First, the water storage bucket 39 is screwed on the threaded hole on the top surface of the sweeper body 1, the water storage bucket 39 is filled with water, and the connection of each part is checked, such as the connection of the annular water pipe 33 with the spray head 36, the lower water pipe 391 with the water pump 32, the output pipe 311 with the distribution pipe 38, etc., the sweeper is started, the water pump 32 starts to work, water is pumped from the water storage bucket 39 to the annular water pipe 33 through the lower water pipe 391, water is uniformly sprayed from the four spray heads 36 on the top of the annular water pipe 33, the ground is moistened, and the cleaning head 2 is used for cleaning, if the spray head 36 or the water pipe is blocked during the water spraying process, the air pump 31 is started, the compressed air generated by the air pump 31 enters the annular air pipe 34 through the output pipe 311 and the distribution pipe 38, and then enters the annular water pipe 33 through the communication pipe 35, due to the action of the one-way valve, the compressed air can only flow in one direction, the accumulated compressed air forms a pulse impact force, which instantaneously blows away the blockage, ensures the smoothness of the spray head 36 and the pipeline, maintains the stable water spraying and dust reducing function, and completes the cleaning task, and then the water storage bucket 39 can be screwed off for cleaning and water preparation for the next time.
