The cleaning assembly 4 is arranged on the side wall of the housing 1.

[0022] A water inlet pipe 11 and a sewage discharge pipe 12 are connected to the housing 1. Both the water inlet pipe 11 and the sewage discharge pipe 12 are communicated with the inner cavity of the housing 1. The water inlet pipe 11 is arranged at the top of the housing 1, and the sewage discharge pipe 12 is arranged on the side wall of the housing 1, and the sewage discharge pipe 12 is located at the bottom of the side wall of the housing 1. In this embodiment, the housing 1 is made of a plastic material with excellent non-stick property, wear resistance and impact resistance. This plastic material is Teflon, so that the adhesion of dirt can be reduced, and further the situation of sewage blockage can be eliminated, ensuring a clean use environment for the housing 1.

[0023] Furthermore, a sewage discharge valve 121 is arranged on the sewage discharge pipe 12. The sewage discharge valve 121 is used to control the opening or closing of the sewage discharge pipe 12. During use, the sewage discharge valve 121 is started, so that the sewage discharge pipe 12 can be controlled to open, and then the dirt in the housing 1 can be discharged from the sewage discharge pipe 12.

[0024] A water distribution pipe 13 is also arranged on the side wall of the housing 1. The water distribution pipe 13 is arranged on the side wall of the housing 1. The water distribution pipe 13 is used to discharge the clean water precipitated in the housing 1. The water distribution pipe 13 is communicated with the inner cavity of the housing 1, and the water distribution pipe 13 is located between the water inlet assembly 2 and the dirt cleaning assembly 3. There are multiple water distribution pipes 13, and the multiple water distribution pipes 13 are arranged on the side wall of the housing 1 at equal intervals. In this embodiment, there are four water distribution pipes 13, and the four water distribution pipes 13 are arranged on the side wall of the housing 1 at equal intervals. In other embodiments not shown, the water distribution pipe 13 can also be two, six or eight, and the specific number of the water distribution pipes 13 can be set according to actual needs. During use, the water distribution pipe 13 can discharge the water in the housing 1 to the outside.

[0025] The water inlet assembly 2 includes a water inlet chamber 21, a water distributor 22 and an energy dissipator 23. The water inlet chamber 21 is a cylindrical structure with openings at both ends. The water inlet chamber 21 is fixedly connected to the inner top wall of the housing 1. The water inlet pipe 11 is communicated with the inner cavity of the water inlet chamber 21. Further, the diameter of the water inlet chamber 21 is larger than the diameter of the water inlet pipe 11, so that when the wastewater flowing into the water inlet pipe 21 flows into the water inlet chamber 21, the wastewater can be energy dissipated.

[0026] Both the water distributor 22 and the energy dissipator 23 are arranged on the water inlet chamber 21. Among them, the water distributor 22 is horizontally arranged in the inner cavity of the water inlet chamber 21, and the energy dissipator 23 is arranged at the bottom of the water inlet chamber 21. The water distributor 22 divides the inner cavity of the water inlet chamber 21 into a first cavity 221 and a second cavity 222. The first cavity 221 is located above the second cavity 222. The water distributor 22 can divide the wastewater in the first cavity 221 into multiple streams of wastewater and then enter the second cavity 222, eliminating the impact of the downward flow velocity of the wastewater, and further enabling the wastewater to be energy dissipated again. In this embodiment, the water distributor 22 is a device with one water inlet and several water outlets, so as to divide one stream of water into multiple streams of water, and further be able to dissipate the energy of the water. The water distributor 22 is a prior art, and its structure and usage process will not be described in detail here.

[0027] The energy dissipator 23 includes a guiding cylinder 231 and a guiding cone 232. The guiding cylinder 231 is fixedly connected to the bottom of the water inlet chamber 21, and the guiding cone 232 is arranged at the bottom of the guiding cylinder 231. There is a notch (not shown in the figure) on the side wall of the guiding cylinder 231, and the notch is located above the guiding cone 232. During use, the wastewater in the second cavity 222 enters the guiding cylinder 231, hits the guiding cone 232 and then flows out from the notch, so that the wastewater can be converted from vertical flow to horizontal flow, and further enables the wastewater to form a static water body and be stored in the inner cavity of the housing 1.

[0028] During use, the wastewater enters the first cavity 221 through the water inlet pipe 11. Since the diameter of the water inlet chamber 21 is larger than the diameter of the water inlet pipe 11, the wastewater can be energy dissipated. Then, the wastewater in the first cavity 221 is divided into multiple streams of wastewater through the water distributor 22 and enters the second cavity 222, so that the wastewater is energy dissipated for the second time. Finally, the wastewater in the second cavity 222 enters the guiding cylinder 231, hits the guiding cone 232 and then flows out from the notch. The energy dissipator 23 converts the wastewater from vertical flow to horizontal flow, so that the wastewater is energy dissipated for the third time, and the wastewater forms a static water body and is stored in the inner cavity of the housing 1.

[0029] The dirt cleaning component 3 includes an air distribution grid 31 and an air inlet pipe 32. The air distribution grid 31 is arranged on the inner bottom wall of the housing 1. The water distribution pipe 32 is located between the energy dissipator 23 and the air distribution grid 31. One end of the air inlet pipe 32 passes through the side wall of the housing 1 and is connected to the air distribution grid 31. In this embodiment, there is one air inlet pipe 32, and the air inlet pipe 32 is communicated with the air distribution grid 31. In other embodiments, please refer to Figure 2 , there are multiple air inlet pipes 32, and multiple air inlet pipes 32 are all communicated with the air distribution grid 31. An air pump (not shown in the figure) is connected to the air inlet pipe 32, so as to vibrate the dirt on the air distribution grid 31. During use, the air pump releases high-pressure gas, and the high-pressure gas enters the air distribution grid 31 after passing through the air inlet pipe 32, so as to vibrate the dirt on the air distribution grid 31, so that the dirt on the air distribution grid 31 vibrates to the bottom of the inner cavity of the housing 1, thereby avoiding the dirt from forming blocks, sticking or blocking on the air distribution grid 31, and enabling the dirt to be discharged through the sewage discharge pipe 12.

[0030] Further, an air path pipe valve 321 is arranged on the air inlet pipe 32, and the air path pipe valve 321 is used to control the opening or closing of the air inlet pipe 32. During use, the air path pipe valve 321 is started, so as to control the opening of the air inlet pipe 32, and further enable the high-pressure gas to enter the air inlet pipe 32.

[0031] The cleaning component 4 includes a water pipe 41, a solenoid valve 42 and a spray head (not shown in the figure). The solenoid valve 42 is arranged on the water pipe 41. The water pipe 41 is arranged on the side wall of the housing 1, and the water pipe 41 is communicated with the inner cavity of the housing 1. The spray head is arranged at one end of the water pipe 41 close to the housing 1, and the spray head is located on the inner wall of the housing 1. Further, the end of the water pipe 41 away from the housing 1 is connected to a water pump (not shown in the figure), and the water pump is electrically connected to the solenoid valve 42. During use, the solenoid valve 42 is opened, the water pump inputs water into the water pipe 41, the water in the water pipe 41 reaches the spray head, and the inner cavity of the housing 1 is cleaned, so as to ensure the use environment of the inner cavity of the housing 1 and timely discharge the dirt. At the same time, when the water treatment device is out of service for a long time, it is not necessary to dismantle the device, and the inner cavity of the housing 1 can be cleaned by combining the dirt cleaning component 3 and the sewage discharge pipe 12.

[0032] Further, the water treatment device further includes a controller (not shown in the figure), and the controller is electrically connected to the sewage discharge valve 121, the air path pipe valve 321 and the solenoid valve 42. During use, the controller controls the start and stop of the sewage discharge valve 121, the air path pipe valve 321 and the solenoid valve 42.

[0033] During use, wastewater enters the first cavity 221 through the water inlet pipe 11. Since the diameter of the water inlet chamber 21 is larger than that of the water inlet pipe 11, the wastewater can be energy-dissipated. Then, the wastewater in the first cavity 221 is divided into multiple streams by the water distributor 22 and enters the second cavity 222, further energy-dissipating the wastewater. Finally, the wastewater in the second cavity 222 enters the guide cylinder 231. After hitting the guide cone 232, the wastewater flows out from the notch, converting the vertical flow of the wastewater into a horizontal flow, energy-dissipating the wastewater three times, and forming a static water body, which is stored in the inner cavity of the housing 1. After standing for a period of time, the dirt in the wastewater precipitates on the air distribution grid 31. The air pipeline valve 321 is started, and thus the intake pipe 32 can be controlled to open. The air pump releases high-pressure gas, and the high-pressure gas enters the air distribution grid 31 after passing through the intake pipe 32, thereby being able to vibrate the dirt on the air distribution grid 31, causing the dirt on the air distribution grid 31 to vibrate to the bottom of the inner cavity of the housing 1, further being able to prevent the dirt from clumping, adhering or blocking in the air distribution grid 31, and enabling the dirt to be discharged through the sewage discharge pipe 12.

[0034] The water treatment device provided by the present invention can dissipate the energy of wastewater three times by setting the water inlet assembly 2. At the same time, the dirt cleaning assembly 3 is set. The high-pressure gas enters the air distribution grid 31 after passing through the intake pipe 32, thereby being able to vibrate the dirt on the air distribution grid 31, causing the dirt on the air distribution grid 31 to vibrate to the bottom of the inner cavity of the housing 1, separating the impurities in the wastewater, and being able to prevent the dirt from clumping, adhering or blocking in the air distribution grid 31. Furthermore, the water distribution is relatively uniform and the water treatment effect is good.
