[0031] In order to solve the technical problem in the prior art that incomplete crushing of waste in sewage treatment equipment causes pipe blockage, the present application provides a sewage treatment equipment and a toilet robot that can fully cut waste and avoid pipe blockage.

[0032] In some embodiments, see Figure 1 and 2 , a sewage treatment device 100 is provided, including: a sewage tank 110, used to contain sewage; a water pump 120, including a motor 121 and an impeller 122, the motor 121 drives the impeller 122 to rotate, the water pump 120 is arranged in the sewage tank 110 and used for sewage discharge; a crushing device, connected to the motor 121, the crushing device is arranged in the sewage tank 110 and used for crushing dirt; wherein the motor 121 drives the crushing device to rotate to crush the dirt in the sewage tank 110, and the motor 121 drives the impeller 122 to rotate to stir the sewage in the sewage tank 110.

[0033] Specifically, the sewage tank 110 is provided with a sewage inlet 112 and a sewage outlet 113. The sewage inlet 112 is used to transport sewage into the sewage tank 110, and the sewage outlet 113 is used for the sewage tank 110 to discharge sewage to the outside. After the sewage and dirt enter the sewage tank 110 through the sewage inlet 112, the large pieces of dirt in the sewage tank 110 can be broken up by the crushing device inside the sewage tank 110. In addition, a water pump 120 is also provided in the sewage tank 110, which is used to pump out the sewage in the water tank and then discharge it from the sewage outlet 113. The water pump 120 includes a motor 121 and an impeller 122. The impeller 122 is connected to the motor 121, and the motor 121 is also connected to the crushing device, which can also drive the crushing device to rotate.

[0034] Furthermore, the crushing device is configured as a rotatable blade or impeller 122, which can break up the dirt. The crushing device is configured near the top side of the sewage tank 110, near the sewage inlet 112; the impeller 122 is configured near the bottom side of the sewage tank 110, near the sewage outlet 113. The crushing device is configured near the sewage inlet 112, so that the crushing device can break up the dirt in the sewage just after the sewage enters the sewage tank 110. The impeller 122 is configured near the bottom of the sewage tank 110 because the dirt is easily deposited at the bottom of the sewage tank 110. Therefore, the impeller 122 is configured near the bottom of the sewage tank 110. The rotation of the impeller 122 can effectively stir the dirt and sewage, so that the dirt can be driven by the impeller 122 to the upper layer of the sewage tank 110 and thus broken up by the crushing device. In addition, the impeller 122 is configured near the sewage outlet 113, so that the impeller 122 can keep the dirt away from the sewage outlet 113 to prevent the sewage outlet 113 from being blocked.

[0035] Furthermore, the motor 121 on the water pump 120 is connected with a crushing device and an impeller 122, and the impeller 122 and the crushing device are respectively arranged at both ends of the motor 121 and are arranged coaxially. By connecting the motor 121 on the water pump 120 with the crushing device to drive the crushing device to rotate, it is possible to avoid setting another motor 121 in the sewage tank 110. In addition, the crushing device and the impeller 122 are coaxially arranged on the motor 121, which can improve the stability of the structure and prevent the eccentric fracture of the motor 121 shaft.

[0036] In this embodiment, the impeller 122 and the crushing device rotate in the sewage tank 110 to fully stir the sewage in the sewage tank 110 and break up the dirt mixed in the sewage. The crushing device breaks up the dirt and the impeller 122 stirs the sewage in the sewage tank 110, so that the dirt in the sewage tank 110 can be completely crushed, avoiding large pieces of dirt remaining after crushing, thereby clogging the pipeline.

[0037] In some embodiments, see Figure 3-4The sewage tank 110 is provided with a sewage inlet 112, and the sewage treatment equipment 100 also includes: a filtering device 140, which is provided with a first accommodating chamber 141, the first accommodating chamber 141 is connected to the sewage inlet 112, and the filtering device 140 separates sewage and dirt; wherein, the crushing device is arranged in the first accommodating chamber 141 to crush the dirt in the first accommodating chamber 141.

[0038] Specifically, a filter device 140 is provided in the sewage tank 110. The filter device 140 is specifically a filter screen. The filter screen is installed at the top of the water pump 120. The filter screen is installed in conjunction with the top surface of the water pump 120, and the filter screen is arranged around the outer peripheral side of the top surface of the water pump 120. The filter screen and the top surface of the water pump 120 together surround and form a first accommodating chamber 141. The top of the filter screen is connected to the sewage inlet 112 at the top of the sewage tank 110. In this way, when sewage and dirt enter the sewage tank 110 through the sewage inlet 112, they first enter the first accommodating space of the filter device 140, and through the through holes 143 on the filter screen, the smaller dirt that can be discharged through the sewage outlet 113 is filtered out through the through holes 143, leaving large pieces of dirt in the first accommodating chamber 141.

[0039] Furthermore, a crushing device is arranged in the first accommodating chamber 141, and large pieces of dirt remain in the filtering device 140. At this time, the motor 121 is controlled to rotate, and the crushing device can crush the large pieces of dirt screened out in the first accommodating chamber 141. Through the cutting of the blade on the crushing device, the large pieces of dirt are broken into small pieces of dirt or residue that can pass through the through hole 143.

[0040] In this embodiment, the filter device 140 is provided with a first accommodating chamber 141, which can retain large pieces of dirt in the first accommodating chamber 141, thereby preventing the sewage outlet 113 from being blocked. In addition, a crushing device is also provided in the first accommodating chamber 141, which can crush the large pieces of dirt left in the first accommodating chamber 141, so that all the dirt in the sewage tank 110 can be discharged through the sewage outlet 113, thereby avoiding pipe blockage.

[0041] In some embodiments, the filter device 140 is disposed at the top of the water pump 120 and connected to the water pump 120 , wherein a protrusion 142 is provided at the bottom of the filter device 140 , and the water pump 120 is provided with a snap-fit ​​component 123 , and the protrusion 142 cooperates with the snap-fit ​​component 123 .

[0042] Specifically, the filter device 140 is arranged at the top of the water pump 120 and is installed in cooperation with the water pump 120. A plurality of clips 123 are arranged on the top surface of the water pump 120. The plurality of clips 123 are arranged in an annular shape and arranged on the outer peripheral side of the top surface of the water pump 120. The clips 123 are two plates with a gap between them, and the gap in the middle can just accommodate the side wall of the filter device 140. The filter screen is inserted between the two plates with a gap and fixed by squeezing between the two plates.

[0043] The clamping member 123 is also provided with a groove, which can cooperate with the protrusion 142 on the filter screen, so that the filter screen can only be removed from the water pump 120 by rotating in a certain direction. The side of the plate is recessed inward to form a groove. When installing, the filter screen is inserted between two adjacent plates, and then the filter screen is rotated so that the protrusion 142 can follow the rotation and enter the groove set on the plate to cooperate with the clamping member 123. In this way, the filter screen can be removed only by rotating in the opposite direction to that during installation.

[0044] In this embodiment, since water is stored in the sewage tank 110 and the internal crushing device will cause a certain impact on the filter screen when crushing, the clamping member 123 cooperates with the protrusion 142 to make the filter device 140 more firmly installed on the water pump 120. In addition, during installation, the filter device 140 can be installed and removed by simply rotating it, which is convenient for manual installation and maintenance.

[0045] In some embodiments, the filter device 140 is a filter screen, and the filter screen is provided with a plurality of through holes 143 , and the diameter of the through holes 143 is smaller than the diameter of the sewage pipe.

[0046] Specifically, the filter device 140 is a filter screen. In order to prevent the dirt passing through the filter device 140 from clogging the sewage outlet 113, the diameter of the through hole 143 on the filter screen can be set to be smaller than the diameter of the sewage outlet 113 and the sewage pipe. In this way, the dirt that can pass through the through hole 143 can also pass through the sewage pipe and the sewage outlet 113, fundamentally preventing the sewage pipe from being blocked due to excessive dirt.

[0047] In some embodiments, see Figure 5-7 The water pump 120 further includes: a first housing 124 accommodating the motor 121 ; a second housing 125 connected to the first housing 124 , the second housing 125 is provided with a second accommodating cavity 126 , the impeller 122 is disposed in the second accommodating cavity 126 , and the second housing 125 is provided with an opening 127 .

[0048] Specifically, the water pump 120 not only includes a motor 121 and an impeller 122, but also has a housing, specifically including a first housing 124 for accommodating the motor 121 and a second housing 125 for accommodating the impeller 122. The first housing 124 is arranged at the top, and is waterproof to prevent sewage from entering the motor 121. The second housing 125 is connected to the first housing 124. The second housing 125 is provided with a second accommodating chamber 126 for accommodating the impeller 122. The impeller 122 rotates in the second accommodating chamber 126. In order to communicate the second accommodating chamber 126 with the sewage tank 110, an opening 127 is provided at the bottom of the second housing 125, so that the opening 127 is communicated with the inside of the sewage tank 110.

[0049] In this embodiment, the second housing 125 is provided with an opening 127 to communicate with the sewage tank 110, so that the impeller 122 can stir the sewage. The second housing 125 is sleeved on the outer peripheral side of the impeller 122 to protect the impeller 122. In addition, the impeller 122 stirs the sewage in the entire sewage tank 110, which requires a relatively high-power motor 121. In order to facilitate the rotation of the impeller 122, the second housing 125 is provided to reduce the pressure of the impeller 122 to rotate, and the impeller 122 rotates more easily in the second housing 125. The second housing 125 is provided on the outer peripheral side of the impeller 122, which can play a role in the siphon effect when the auxiliary water pump 120 pumps water, so that the water pump 120 can pump water from here.

[0050] In some embodiments, it also includes: the water pump 120 is provided with a water outlet pipe 128, and the water outlet pipe 128 is provided in the second shell 125.

[0051] Specifically, in order to facilitate the water pump 120 to pump water and send it to the sewage outlet 113 at the sewage tank 110, a water outlet pipe 128 is provided on the second housing 125. Since the second housing 125 can assist siphoning, the water outlet pipe 128 is provided on the second housing 125 to facilitate the water discharge of the water pump 120. In addition, the impeller 122 rotates at the second housing 125 to play a stirring role and prevent dirt from clogging the water outlet pipe 128.

[0052] In some embodiments, a valve is provided at the end of the water outlet pipe 128 .

[0053] Specifically, in order to manually control the inflow and outflow of water in the sewage tank 110, a valve is provided at the end of the water outlet pipe 128 to control the water outlet of the water pump 120. The opening and closing of the valve is coordinated with the rotation of the impeller 122 in the sewage tank 110. When the impeller 122 and the blade rotate to perform the stirring and crushing work, the valve is closed; when the stirring and crushing is completed, the valve is opened to discharge the sewage. Therefore, the valve can be provided to circulate the crushing and stirring process and the sewage discharge process in the sewage tank 110, which is convenient for the crushing work.

[0054] In this embodiment, a valve is provided at the water outlet pipe 128 to control the water outlet of the water pump 120. In addition, a sewage pipe is connected between the water outlet pipe 128 and the sewage outlet 113, and a valve is installed at the water outlet pipe 128 to facilitate replacement of the sewage pipe.

[0055] In some embodiments, the sewage tank 110 is provided with a sewage outlet 113 , and the sewage treatment equipment 100 further includes: a sewage pipe, one end of which is connected to the water pump 120 , and the other end of which is connected to the sewage outlet 113 .

[0056] Specifically, the sewage treatment equipment 100 further includes a sewage pipe, which connects the water outlet pipe 128 on the water pump 120 and the sewage outlet 113 , and sends the sewage sent out by the water pump 120 into the sewage outlet 113 through the sewage pipe.

[0057] In some embodiments, the sewage tank 110 further includes a tank cover 115 , and the tank cover 115 is provided with a sewage inlet 112 and a sewage outlet 113 .

[0058] Specifically, a box cover 115 is provided on the top of the sewage tank 110, which is detachably connected to the sewage tank 110. The box cover 115 is provided with a sewage inlet 112 and a sewage outlet 113, wherein the sewage inlet 112 is used for sewage intake and the sewage outlet 113 is used for sewage discharge.

[0059] In a second aspect, the present application provides a toilet robot, which includes a sewage treatment device 100 .

[0060] Specifically, the sewage treatment equipment 100 is a part of the entire toilet robot. The sewage passing through the toilet robot needs to be processed and crushed by the sewage treatment equipment 100 to prevent the entire toilet robot from being blocked.
