[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The domestic sewage front-end treatment equipment of the present invention drives the linear module with the gathering claw to move linearly in the water inlet hole through the power module, so that the gathering claw drives the debris on the lower water cover plate to move to the end of the water inlet hole for gathering, and cooperates with the stripping teeth to scrape off the soft debris on the gathering claw to prevent the soft debris from entering the bottom trough due to rotation.

[0026] 2. The domestic sewage front-end treatment equipment of the present invention, through the setting of the water guide plate, can gather the water flow left from the water inlet hole at the edge of the lower water cover plate, and flow out from the impact port to impact the blades on the rotating shaft, so that the rotating shaft can drive the transmission belt in the linear module to rotate; thus, it has the advantage of being able to gather debris without electricity and save energy.

[0027] 3. The present invention allows the cleaning component to be installed inside the bottom tank; it can have the following advantages: 1. By driving the gathering claws to rotate by a motor, the hair located above the drain cover plate can be cleaned in time to prevent the hair from being washed into the bottom tank by the water flow on the drain cover plate for a long time, thereby eliminating or reducing the cleaning of the bottom tank; 2. It prevents the hair from covering too much space on the drain cover plate and affecting the water inlet area; 3. The gathered hair is easy to grab or clean after bathing, effectively preventing a small amount of hair from adhering to the drain cover plate, which makes it difficult to clean.

[0028] 4. The domestic sewage front-end treatment equipment of the present invention forms a water storage chamber through a water storage plate, a water guide plate and the inner wall of the bottom trough. The water volume m in the water storage chamber impacts the blade below the impact port once to start the power module to make the transmission belt run for one or more cycles, effectively ensuring that the gathering claws protruding from the water inlet of the lower water cover plate are all located inside the bottom trough in the initial state; effectively avoiding the protruding gathering claws from affecting the appearance, and preventing the gathering claws from protruding from the lower water cover plate when in standby mode, which may cause injuries or discomfort to the soles of the feet when the user steps on them.

[0029] 5. The domestic sewage front-end treatment equipment of the present invention, through the opening of the grabbing cavity and the setting of the pressing plate, can lower the pressing plate by fingers other than the thumb when grabbing the accumulated hair, and then use the palm and thumb to slide the hair accumulated on the drain cover plate, so that the hair is located in the palm, which is further convenient for grabbing the hair; it can avoid a small amount of hair residue, and the situation that a small amount of hair sticks to the drain cover plate and is difficult to handle occurs.

[0030] 6. The domestic sewage front-end treatment equipment of the present invention can manually adjust the position of the gathering claws through the further setting of the positioning mechanism, thereby ensuring the adjustment of the initial position of the gathering claws during long-term operation of the equipment, and further ensuring that the gathering claws are located inside the bottom tank after the operation stops.

[0051] Embodiment 1

[0052] See also Figure 1 - Figure 2 The domestic sewage front-end treatment equipment of the present invention comprises a water discharge cover plate 2, a plurality of water inlet holes 21 are provided on the top of the water discharge cover plate 2, and the water inlet holes 21 are in the shape of long strips;

[0053] The cleaning assembly 4 also includes a gathering claw 41, the claw teeth 411 of the gathering claw 41 are installed corresponding to the water inlet hole 21, and the claw teeth 411 protrude from the water inlet hole 21, and the cleaning assembly 4 also includes a linear module 42 and a power module 6 for starting the gathering claw 41 to move in the water inlet hole 21 to gather debris on the surface of the water lower cover plate 2, and the power module 6 is used to drive the linear module 42;

[0054] The cleaning assembly 4 also includes a stripping mechanism 5, which is used to strip the debris gathered on the gathering claw 41;

[0055] The linear module 42 includes a transmission belt 422 installed parallel to the water inlet hole 21, and transmission wheels 421 are provided at both ends of the transmission belt 422. The gathering claw 41 is installed on the transmission belt 422, and the transmission wheels 421 at both ends of the transmission belt 422 are respectively installed near both ends of the water inlet hole 21;

[0056] The stripping mechanism 5 includes a stripping tooth 51 disposed at one end of the water inlet 21 where debris is gathered. The tooth grooves 52 between the stripping teeth 51 are adapted to the width of the claw teeth 411 of the gathering claw 41. The claw teeth 411 of the gathering claw 41 slide downward out of the tooth grooves 52 of the stripping tooth 51.

[0057] The power module 6 is a motor, which drives the transmission wheel 421 to rotate;

[0058] Specifically, the two transmission wheels 421 are respectively installed below the end of the water inlet hole 21, and the distance between the transmission wheel 421 and the end of the water inlet hole 21 is greater than or equal to the distance between the transmission wheel 421 and the top of the claw teeth 411 in the gathering claw 41, which can ensure that the stripping claw will not be blocked by the end of the water inlet hole 21 when rotating with the transmission wheel 421 as the center.

[0059] The tooth groove 52 of the stripping tooth 51 is installed corresponding to the water inlet hole 21 just above or just below the water launch cover plate 2, and the stripping tooth 51 is slidably connected to the water launch cover plate 2 along the direction of the water inlet hole 21. The sliding stroke of the stripping tooth 51 on the water launch cover plate 2 is greater than the horizontal distance between the axis of the transmission wheel 421 and the adjacent water inlet hole 21, and a first elastic reset mechanism 53 is provided between the stripping tooth 51 and the water launch cover plate 2.

[0060] The gathering claw 41 is fixedly connected to the transmission belt 422 .

[0061] Working principle:

[0062] The transmission wheel 421 in the linear module 42 is driven to rotate by the power module 6. The rotation of the transmission wheel 421 will cause the gathering claw 41 to move linearly in the water inlet hole 21. Since the claw teeth 411 of the gathering claw 41 protrude from the water inlet hole 21, the gathering claw 41 moves linearly in the water inlet hole 21, which can drive the debris located on the lower water cover plate 2 to move to the end of the water inlet hole 21 and gather.

[0063] When the claw teeth 411 in the gathering claw 41 move to the tooth grooves 52 in the stripping teeth 51, the gathering claw 41 will rotate due to the transmission wheel 421 close to the stripping teeth 51, and the rotating stripping teeth 51 will push the stripping teeth 51 to slide under the water discharge cover plate 2, and the claw teeth 411 in the gathering claw 41 will slide relatively in the tooth grooves 52 at the same time, that is, the stripping teeth 51 can scrape off the soft debris on the gathering claw 41, and prevent the soft debris from entering the bottom groove 1 due to rotation;

[0064] Among them, because the distance between the transmission wheel 421 and the end of the water inlet hole 21 is greater than or equal to the distance between the transmission wheel 421 and the top of the claw tooth 411 in the gathering claw 41, and the sliding stroke of the stripping tooth 51 on the water discharge cover plate 2 is greater than the horizontal distance between the axis of the transmission wheel 421 and the adjacent water inlet hole 21, it can ensure that when the stripping claw rotates with the transmission wheel 421 as the center, it will not be blocked or restricted by the end of the water inlet hole 21 and the stripping tooth 51.

[0065] Among them, the first elastic reset mechanism 53 is preferably a spring sleeve or a slide rail with a spring, which plays a role in resetting the stripping tooth 51 when the gathering claw 41 is separated from the stripping tooth 51.

[0066] Embodiment 2

[0067] See also Figure 3As a variation of the first embodiment, the problem that the peeling mechanism 5 in the first embodiment is too complicated is solved.

[0068] The end of the water discharge cover plate 2 and a part of the water inlet hole 21 form a stripping tooth 51;

[0069] The gathering claw 41 is rotatably connected to the transmission belt 422 via the spring shaft 43;

[0070] Alternatively, the gathering claw 41 is rotatably connected to the transmission belt 422 via a rotating shaft, and an elastic reset member is provided between the rotating shaft and the transmission belt 422. Specifically, the elastic reset member is a torsion spring, and the gathering claw 41 is automatically reset after being rotated under force via the torsion spring.

[0071] In this embodiment:

[0072] The end of the water discharge cover plate 2 and the water inlet hole 21 partially constitute a stripping tooth 51, thereby having the function of the stripping tooth 51 in the above-mentioned embodiment 1 to prevent soft entry into the bottom groove 1. However, since the stripping tooth 51 in this embodiment cannot slide on the water discharge cover plate 2, it will affect the gathering claw 41 rotating under the transmission wheel 421 to the bottom of the transmission belt 422. Therefore, the gathering claw 41 is rotatably connected to the transmission belt 422 through the clockwork shaft 43. After the gathering claw 41 enters the stripping tooth 51 in this embodiment, the gathering claw 41 rotates through the clockwork shaft 43, so that the gathering claw 41 slides out of the stripping tooth 51, that is, it can effectively make the debris gather at one end of the water discharge cover plate 2.

[0073] Embodiment 3

[0074] See also Figure 4 As a further improvement of the power module 6 in the first or second embodiment, the power module 6 includes a water guide plate 63 and a rotating shaft 61. An impact port 64 is provided at the edge of the water guide plate 63 or an impact port 64 is opened on the water guide plate 63. The rotating shaft 61 is installed below the impact port 64 through a bearing. The rotating shaft 61 is installed with a blade 62 for receiving the impact of water flow and carrying the rotating shaft 61 to rotate. The rotating shaft 61 is connected to the transmission wheel 421 in the linear module 42 through a synchronous belt.

[0075] In this example:

[0076] The water flow will preferentially flow into the bottom trough 1 from the water inlet hole 21 located at the edge of the lower water cover plate 2. By setting the water guide plate 63, the water flow can be gathered on the water guide plate 63, and flow out from the impact port 64 to impact the blades 62 on the rotating shaft 61, so that the rotating shaft 61 can drive the transmission belt 422 in the linear module 42 to rotate; that is, compared with the first embodiment, the device also has the advantage of not requiring electric drive and saving energy.

[0077] Furthermore, the impact port 64 is of rectangular or flat design, so that the water flows out of the impact port 64 in a rectangular or waterfall shape, thereby facilitating the water flow on the guide plate to impact the blades 62 below the impact port 64 .

[0078] Furthermore, the water guide plate 63 is an oblique plate or a funnel-shaped arrangement, and the impact opening 64 is opened at the lowest point of the water guide plate 63 .

[0079] Furthermore, an overflow port 7 higher than the impact port 64 is provided on the water guide plate 63 . The overflow port 7 is located at the highest point of the water guide plate 63 . The overflow port 7 is used to allow excess water in the water storage chamber 8 to flow through the bottom trough 1 and then be discharged from the drain port 3 .

[0080] Embodiment 4

[0081] A front-end treatment device for domestic sewage, comprising a bottom tank 1, a water discharge cover plate 2 mounted on the top of the bottom tank 1, and a cleaning component 4 mounted inside the bottom tank 1;

[0082] See also Figure 5 or Figure 6 When the drain cleaning mechanism in this embodiment is that of embodiment 1 or embodiment 2, the gathering claw 41 moves back and forth in the water inlet hole 21, which can have the following advantages: 1. The gathering claw 41 is driven by the motor to rotate, so that the hair above the drain cover plate 2 can be cleaned in time, and the hair is prevented from being washed into the bottom tank 1 by the water flow on the drain cover plate 2 for a long time, thereby eliminating or reducing the cleaning of the inside of the bottom tank 1; 2. The hair is prevented from covering too many positions on the drain cover plate 2, affecting the water inlet area; 3. The gathered hair is easy to grab or clean after bathing, which effectively prevents a small amount of hair from adhering to the drain cover plate 2, making it difficult to clean.

[0083] Embodiment 5

[0084] A domestic sewage front-end treatment device, comprising a bottom tank 1, a water discharge cover plate 2 mounted on the top of the bottom tank 1, and a cleaning component 4 mounted inside the bottom tank 1;

[0085] See also Figure 7 When this embodiment is a further improvement of the third embodiment, it further includes a water storage plate 9 for closing the impact port 64. The water storage plate 9, the water guide plate 63 and the inner wall of the bottom tank 1 form a water storage chamber 8, and the water storage chamber 8 is used to store water m. The water storage plate 9 is movably mounted on the impact port 64 through the control unit 10;

[0086] The control unit 10 starts the water storage plate 9 to intermittently open the impact port 64 through the water volume m, and the water volume m in the water storage chamber 8 impacts the blade 62 located below the impact port 64 once to start the power module 6 to make the transmission belt 422 run for one or more cycles;

[0087] The water storage plate 9 is horizontally slidably mounted on the impact port 64, and the control unit 10 is an electric telescopic rod;

[0088] Alternatively, the water storage plate 9 is installed on the impact port 64 via a rotating shaft, and the control unit 10 is a motor drivingly connected to the rotating shaft.

[0089] In this embodiment, since the water storage plate 9, the water guide plate 63 and the inner wall of the bottom trough 1 form a water storage chamber 8, that is, the water storage chamber 8 can store a water volume m, the electric control unit 10 can control the duration of opening the impact port 64 to ensure that the water volume m in the water storage chamber 8 flows out through the impact port 64 without exceeding the amount to impact the blade 62 on the rotating shaft 61. Since the water volume m is limited, the water volume m impacts the rotating roller below the impact port 64 once to start the power module 6, so that the transmission belt 422 runs for one or more cycles, that is, it can effectively ensure that the gathering claws 41 protruding from the water inlet of the lower water cover plate 2 are all located inside the bottom trough 1 in the initial state; effectively avoid the protruding gathering claws 41 affecting the appearance, and prevent the gathering claws 41 from protruding from the lower water cover plate 2 in standby mode, which may cause injuries or discomfort to the soles of the feet when the user steps on them;

[0090] Furthermore, in this embodiment, it can also include a storage module 11 and a power generation module 12 electrically connected to the storage module 11. The rotating shaft 61 is transmission-connected to the power generation mechanism. When the water volume m impacts the blades 62 on the rotating shaft 61, power is generated and stored in the electrically connected storage module 11. The electric control unit 10 is then used to start the water storage plate 9. Thus, the kinetic energy of the water volume m impacting the blades 62 is recovered, thereby further achieving the effect of saving energy.

[0091] Embodiment 6

[0092] See also Figure 8 As a variation of the fifth embodiment, the difference from the fifth embodiment is that:

[0093] The water storage plate 9 is installed on the edge of the impact port 64 through the spring shaft 43. The control unit 10 is mutually attracted magnets 10a. The magnets 10a are installed on the edge of the water storage plate 9 and / or the impact port 64. The magnets 10a cause the water storage plate 9 to rotate under the gravity of the water volume m on the water storage plate 9.

[0094] In this embodiment, the control unit 10 can automatically open and close the water storage plate 9 under the control of the water volume m, thereby intermittently rotating the rotating shaft 61, so that the transmission belt 422 runs one or more circles, that is, the gathering claw 41 can effectively make the gathering claw 41 located inside the bottom groove 1 after running.
