[0053] Figures 1-27 This is one or more embodiments of the present utility model.

[0054] like Figures 1-3 , Figure 16As shown, the wastewater tank solid waste treatment structure 100 includes: a wastewater tank body 110 with a wastewater receiving cavity 1101; and a solid waste collection assembly 120, which is detachably installed within the wastewater receiving cavity 1101. The solid waste collection assembly 120 includes: a solid waste bin 1200, a slag discharge door 130, an anti-fouling grip 140, a slag discharge operation part 150, and a door drive coupling mechanism 160. After the solid waste collection assembly 120 is engaged with the wastewater receiving cavity 1101, the anti-fouling grip 140 can be exposed to the outside air and isolated from the wastewater receiving cavity 1101; alternatively, the anti-fouling grip 140 can be concealed within the wastewater tank body 110. The solid waste bin 1200 can be made of rigid materials such as metal or plastic, or a mesh bag made of flexible materials. The solid waste bin 1200 has fluid passage zones 1201 distributed on its walls, and also has a fluid inlet 1202 and a slag discharge outlet 1203. The fluid inlet 1202 is used to guide the waste sucked in by the cleaning equipment into the solid waste bin 1200. The fluid passage zones 1201 can be mesh, grids, holes, or slits, with small openings to prevent solid waste from passing through and failing to collect it. These mesh, grids, holes, or slits allow liquid waste and gas to pass through, such as water, while trapping solid waste within the solid waste bin 1200 to achieve the function of collecting solid waste. The slag discharge outlet 1203 is used to discharge the collected solid waste from the solid waste bin 1200 after the slag discharge door 130 is opened.

[0055] The slag discharge door 130 is connected to the main body of the solid waste bin 1200 and can move between a closed position and an open position. In the closed position, the slag discharge door 130 closes the slag discharge port 1203; in the open position, the slag discharge port 1203 is opened to allow slag discharge. The opening and closing of the slag discharge door 130 is referred to as the opening and closing movement of the slag discharge door.

[0056] In some embodiments, the slag discharge door 130 can be disposed on any surface of the solid waste bin 1200, or it can be fixed to the anti-fouling grip part 140. In one embodiment, for ease of opening, the slag discharge door 130 can be disposed on the side of the solid waste bin 1200, such as... Figure 2As shown. The anti-fouling grip 140 is isolated from the sewage container 1101, and the anti-fouling grip 140 does not come into contact with the sewage container 1101 to prevent the anti-fouling grip 140 from being contaminated by garbage. In practice, the anti-fouling grip 140 is connected to the main body of the solid waste bin 1200. The anti-fouling grip 140 is used for users to hold, which facilitates the disassembly and installation of the solid waste collection assembly 120 from the sewage tank body 110. The gripping surface 1401 of the anti-fouling grip 140 is located outside the sewage container 1101, that is, the gripping surface 1401 is isolated from the sewage container cavity, so that the gripping surface 1401 is not contaminated. In other words, the part held by the user is set away from the sewage container 1101 to prevent the part of the gripping surface 1401 that is held by the user from getting contaminated, and to avoid the problem of dirty hands when the user holds or removes the solid waste collection assembly 120 from the sewage tank body 110. The gripping surface 1401 may consist of one or more surfaces disposed on the outside of the solid waste collection assembly 120.

[0057] The slag discharge operation unit 150 is isolated from the sewage receiving chamber 1101 and serves as the physical part through which the user directly performs operations. Its overall physical structure is located within a spatially connected area to prevent contamination of the slag discharge operation unit 150 by garbage. The slag discharge operation unit 150 is positioned within the spatially connected area of ​​the anti-fouling grip unit 140 to prevent the user from getting their hands dirty with garbage when touching, pressing, or operating the slag discharge operation unit 150 to open the slag discharge door 130 to empty the garbage. Through manual operation of the slag discharge operation unit 150, the door drive coupling mechanism 160 directly or indirectly drives the slag discharge door 130 to perform opening and closing movements, including opening and closing the slag discharge door 130. The door drive coupling mechanism 160 can be implemented using mechanical transmission or electronic drive. If electronic drive is used, it can be equipped with a motor and drive circuit board to achieve the desired solution. There are multiple ways to implement this solution. The methods listed in this article are only a part of the implementation methods. However, the implementation of the solution should not be limited to the methods listed in this article. The specific drive transmission method of the door drive coupling mechanism 160 should not be used as a limitation on the scope of protection of this solution.

[0058] In one embodiment, the spatially associated region can be the surface of the body structure of the anti-fouling grip 140, including the gripping surface 1401. Alternatively, the spatially associated region can be the outer surface and interior of the body structure of the anti-fouling grip 140; that is, the spatially associated region can be located on the surface of the anti-fouling grip 140 or within it. In another embodiment, the slag discharge operation part 150 is spaced apart from the body structure of the anti-fouling grip 140. That is, the slag discharge operation part 150 is not located on the anti-fouling grip 140 but is spaced apart from it, or located outside the anti-fouling grip 140. In this embodiment, the spatially associated region can be defined as a hemispherical spatial domain Z with a radius R ≤ 80 mm, centered at the geometric center O of the gripping surface 1401. Figure 4 As shown, the slag discharge operation unit 150, which serves as the physical part where the user directly performs the operation, is located outside the main body structure of the anti-fouling grip unit 140. In practice, the slag discharge operation unit 150 is located above the main body of the anti-fouling grip unit 140, in an area with a certain height difference, and can be connected to the slag discharge door via a transmission structure; alternatively, the slag discharge operation unit 150 can be located outside the edge of the anti-fouling grip unit 140, at a certain distance, and connected to the slag discharge door via a connecting shaft or transmission structure. Regardless of the design, the slag discharge operation unit 150 cannot be directly connected to the inside of the sewage containing cavity 1101, thus preventing direct contamination by waste. In this embodiment, the core part S of the slag discharge operation unit 150, where the user applies force, is located within a hemispherical spatial domain Z with a radius R ≤ 80 mm, centered at the geometric center O of the gripping surface 1401. To prevent dirt and grime from contaminating the user's hands, this solution, through in-depth research into ergonomics and product structure layout, found that confining the core part of the slag discharge operation unit 150 within a specific spatial domain is key to resolving the aforementioned contradiction. The radius R of the hemispherical spatial domain Z is limited to ≤80mm, based on the following principles and design requirements:

[0059] Ergonomic principles: Based on the size of an adult's hand and the natural range of motion of the thumb / index finger (with the thumb pad as the operating point and the other four fingers gripping), a spherical space with a radius of 80mm, centered on the geometric center of the gripping surface, represents the maximum natural range of motion that the thumb or index finger can easily and comfortably cover without significant wrist movement during single-handed operation. This range ensures maximum ease of use.

[0060] Miniaturization Requirements: Cleaning equipment is trending towards compactness, and the volume of the wastewater tank directly determines the overall size of the machine. As a component of the wastewater tank, the size of the grip must be strictly constrained. The limit of R≤80mm ensures that the sludge discharge operation section can be integrated into a compact grip without excessive expansion. If the R value is too large (e.g., >80mm), the volume of the grip will have to be significantly increased to achieve the operating area, thus violating the miniaturization design goal, occupying too much space, and causing an uncoordinated overall structure. To verify the effectiveness of R≤80mm, the inventors designed the following comparative experiment: Table 1 shows the impact of the size of the spatial domain Z on the product experience.

[0061]

[0062]

[0063] The above test results show that when R > 80mm, the improvement in ease of operation is no longer significant, but its negative impact on the grip and even the overall size of the machine begins to increase dramatically. Therefore, R = 80mm is an optimal critical point that balances ease of operation and miniaturization. Limiting R to ≤ 80mm is not an arbitrary choice, but rather the optimal technical solution that can simultaneously meet two conflicting requirements, derived after extensive ergonomic research and structural design verification.

[0064] The solid waste treatment device 100 of this solution includes a solid waste collection assembly 120 for convenient collection and treatment of solid waste, and an anti-fouling grip 140 to solve the problem of dirty hands when users hold the device while emptying the waste. The slag discharge operation part 150 is confined to the spatial association area of ​​the anti-fouling grip 140 to prevent users from being contaminated by waste when operating the slag discharge door 130, i.e., touching the slag discharge operation part 150. The solution considers and avoids dirty hands from both the gripping of the solid waste collection assembly 120 and the operation of the slag discharge door 130. The solution includes a slag discharge door 130 and a door drive coupling mechanism 160 (referred to as a door control mechanism). The slag discharge operation part 150 and the motion transmission structure enable quick opening of the door and smooth waste disposal, further preventing waste from sticking to hands. This solution effectively solves the problems of dirty hands, low waste disposal efficiency, and negative user experience associated with existing cleaning equipment when cleaning solid waste, thus further improving the user experience. Both the anti-fouling grip section 140 and the slag discharge operation section 150 must be protected from contamination by waste, ensuring that the two key steps of "gripping" and "opening" the solid waste collection assembly 120 do not result in dirty hands. Gripping is for removing or detaching the solid waste collection assembly from the wastewater tank body; opening is for opening the slag discharge door after removing the solid waste collection assembly and then emptying the solid waste inside. Both of these key steps are performed without getting hands dirty. These two key steps are crucial factors that distinguish this technology from existing technologies.

[0065] In one embodiment, such as Figure 5 , Figure 6 As shown, the slag discharge door 130 itself constitutes at least a part of the door body drive coupling mechanism 160. The slag discharge door 130 is provided with a lever part 1301 exposed on the anti-fouling grip part 140, and may also have a fastening part 1302. The lever part 1301 is used to operate and trigger the movement of the slag discharge door 130. The fastening part 1302 is formed or disposed between the slag discharge door body and the lever part 1301, so that the slag discharge door body and the anti-fouling grip part 140 can cooperate, and the fastening part 1302 can directly affect the opening and closing of the slag discharge door 130. The user can directly operate the lever part 1301, and the force is transmitted to the slag discharge door 130 through the fastening part 1302 to open or close the slag discharge door 130. In this embodiment, the fastening part 1302 can be understood as the door body drive coupling mechanism 160 of this solution. The lever part 1301 can be understood as the slag discharge operation part 150 of this solution.

[0066] In another embodiment, such as Figures 7-21As shown, the door drive coupling mechanism 160 includes: a motion transmission structure 1601, connecting the slag discharge operation part 150 and the force application end of the slag discharge door 130; wherein, the linear or rotary drive action of the slag discharge operation part 150 is converted into the opening and closing motion of the slag discharge door 130 through the motion transmission structure 1601. The linear drive action can be a straight line, a broken line, etc., including pressing, pulling, pressing, flicking, and linear pushing in a certain direction. In one embodiment, such as Figures 7-14 As shown, several different scenarios illustrate how the slag discharge gate 130 is opened via the linear drive action of the slag discharge operation unit 150. The drive action of the slag discharge operation unit 150 is linear, and the motion transmission structure 1601 transmits the linear displacement of the slag discharge operation unit 150 to the force application end of the slag discharge gate 130. For example... Figure 7 , Figure 8 As shown, by actuating the slag discharge operation unit 150, the slag discharge door 130 is opened under the force transmission of the door body drive coupling mechanism 160. (See diagram) Figure 9 , Figure 10 , Figure 11 As shown in some embodiments, pressing the slag discharge operation part 150 drives the door body drive coupling mechanism 160 to further drive the opening and closing of the slag discharge door 130. The door body drive coupling mechanism 160 may include a motion transmission structure 1601, which includes a rigid transmission element 16011, such as... Figure 11 As shown, the rigid transmission element 16011 has its first end 160111 fixedly connected to the slag discharge operating part 150; its second end 160112 is driven and connected to the slag discharge gate 130, enabling it to open and close. In another embodiment, such as Figure 12 , Figure 13 , Figure 14 As shown, pressing the slag discharge operation unit 150 drives the door body drive coupling mechanism 160 to move, and the movement of the door body drive coupling mechanism 160 is then converted into the opening and closing movement of the slag discharge door 130.

[0067] In another implementation, such as Figures 15-22 As shown, the driving action of the slag discharge operation unit 150 is a rotary driving action, and the motion transmission structure 1601 includes a transmission assembly, which is implemented, for example, by a transmission shaft 16010. Figure 16 As shown, the transmission shaft 16010 has its input end fixedly connected to the slag discharge operation unit 150, and its output end driving the slag discharge gate 130. The rotation of the slag discharge operation unit 150 drives the transmission assembly to move, and the movement of the transmission assembly is then converted into the opening and closing movement of the slag discharge gate 130. In other implementations, the input end of the transmission assembly is fixedly connected to the slag discharge operation unit 150, and the output end of the transmission assembly drives the slag discharge gate 130 to realize the opening and closing movement of the slag discharge gate.

[0068] In some implementations, the motion transmission structure, i.e., the transmission assembly, is configured in any of the following three ways: a, b, and c.

[0069] (a) Direct connection type: The output end of the motion transmission structure 1601 serves as the rotation axis of the slag discharge gate 130 and is fixedly connected to the slag discharge operation unit 150; such as Figures 16-18 The slag discharge door 130 shown opens and closes under the drive of the drive shaft. In this configuration, the door drive coupling mechanism can be understood as the drive shaft.

[0070] (b) Crank-type: The motion transmission structure 1601 includes a crank-connecting rod mechanism, with its input end connected to the slag discharge operating unit and its output end connected to the slag discharge gate. The slag discharge gate 130 is connected via the crank-connecting rod structure 170; as shown... Figure 18 , Figure 19 The crank-connecting rod structure 170 drives the opening and closing of the slag discharge door 130, meaning its opening and closing motion can be converted into the motion of the slag discharge door 130 by the rotational motion of the slag discharge operating part 150. In this method, the door drive coupling mechanism can be understood as a crank-connecting rod structure.

[0071] (c) Cam type: The motion transmission structure 1601 includes a cam pusher mechanism, the input end of which is connected to the slag discharge operation unit, and the output end drives the slag discharge gate. The output end can drive the slag discharge gate 130 through the cam pusher structure 180.

[0072] like Figure 20 , Figure 21 As shown, the cam pusher structure 180 drives the opening and closing of the slag discharge door 130, meaning that its opening and closing motion can be converted into the motion of the slag discharge door 130 by the rotational motion of the slag discharge operating part 150. In this method, the door drive coupling mechanism can be understood as a cam pusher structure.

[0073] When the motion transmission structure is configured as a direct-drive structure, it includes a drive shaft 16010, which can form the hinge shaft of the slag discharge door 130; the opening direction of the slag discharge door 130 is outward flipping, such as... Figure 16 As shown.

[0074] In one embodiment, such as Figure 22As shown, the anti-fouling grip 140 is connected to the main body of the solid waste bin 1200 via an overhead fixing column 190. The overhead fixing column 190 creates a gap between the main body of the solid waste bin 1200 and the anti-fouling grip 140. The overhead fixing column 190 creates a splash-proof isolation gap 1000 between the inner surface of the anti-fouling grip 140 and the upper edge of the fluid passage area 1201. This splash-proof isolation gap 1000 prevents users from getting their hands dirty with garbage when gripping the edge of the anti-fouling grip 140. In one embodiment, a door drive coupling mechanism 160 passes through the overhead fixing column 190 and the anti-fouling grip 140. The door drive coupling mechanism 160 can be a motion transmission structure 1601, with one end connected to the slag discharge operation unit 150 and the other end connected to the slag discharge door 130, to better protect the motion transmission structure 1601. In other embodiments, anti-slip textures or anti-slip serrations can be provided on the slag discharge operation section 150 to increase friction during operation and prevent the problem of slipping out of the hand.

[0075] In one embodiment, a magnetic adsorption structure 111 is provided between the slag discharge door 130 and the solid waste bin 1200, such as... Figure 2 As shown, the magnetic adsorption structure 111 can be a magnet, and it can be located on the slag discharge door 130 or on the solid waste bin 1200. Similarly, it can also be located inside the slag discharge door 130 or inside the solid waste bin 1200. The magnetic adsorption structure 111 is configured to keep the slag discharge door 130 and the solid waste bin 1200 tightly closed when the slag discharge door 130 is closed.

[0076] In one embodiment, such as Figures 23-25 As shown, the sewage tank body 110 is equipped with a negative pressure interface 1100 that communicates with the suction motor. The negative pressure interface 1100 is connected to the suction motor to apply the negative pressure generated by the suction motor to the sewage tank body 110. The height H1 of the central axis of the negative pressure interface 1100 does not exceed the height Hm of the highest point of the fluid passage area 1201 on the solid waste bin 1200, so that the suction of the negative pressure interface 1100 can quickly reach the bottom of the fluid passage area 1201, thereby improving the impact of fluid waste accumulation at the bottom of the solid waste collection assembly 120. The problem with solid waste suction stems from the fact that liquid waste tends to accumulate downwards under gravity, and due to the viscosity and inertia of the liquid, it adheres to the solid waste bin. Consequently, it tends to accumulate at the bottom of the fluid passage area. This design prevents liquid waste and airflow from accumulating at the bottom of the solid waste collection assembly 120, thus avoiding the accumulation of liquid waste and airflow that would otherwise take up space in the solid waste bin and hinder solid waste suction. This design achieves rapid suction of fluid waste accumulated at the bottom of the solid waste collection assembly 120, achieving the following technical objectives:

[0077] 1. Optimized fluid path: The flow path of sewage from the fluid passage zone 1201 to the negative pressure port 1100 is significantly shortened, reducing fluid resistance and avoiding the "vortex" or "dead water zone" caused by excessive negative pressure port in the prior art. This promotes the rapid passage of fluid waste (including liquid and gaseous waste) through the fluid passage zone 1201 and avoids accumulation.

[0078] 2. Improved suction efficiency: The negative pressure suction of the suction motor acts more directly on the entire area of ​​the solid waste compartment 1200, especially the top and bottom, ensuring efficient use of suction power and effectively preventing liquid waste and airflow from lingering or accumulating in the compartment. It is particularly effective in improving the suction of lightweight, fluffy solid waste (such as hair and paper scraps).

[0079] 3. Reduced risk of clogging: Smooth fluid movement reduces the likelihood of fluid debris adhering to the surface of the fluid passage zone 1201, thereby reducing the risk of clogging.

[0080] This utility model also provides a cleaning device 200, which includes the aforementioned sewage tank solid waste treatment structure 100 and a suction motor 300. The suction motor 300 is connected to the sewage tank solid waste treatment structure 100 through a negative pressure interface 1100. The negative pressure generated by the suction motor 300 creates a negative pressure within the sewage tank solid waste treatment structure 100, further enabling the cleaning device to suck waste into the solid waste bin 1200 from the fluid inlet 1202 under the suction of the suction motor 300 when cleaning the surface to be cleaned. Due to the arrangement of the fluid passage area 1201, liquid waste and airflow can pass through the fluid passage area 1201, wherein the airflow enters the suction motor 300 from the negative pressure interface 1100 of the sewage tank body 110.

[0081] Cleaning equipment 200 can be floor scrubbers, cleaning robots, window cleaning robots, countertop cleaners, or kitchen surface cleaners. Let's take a floor scrubber as an example... Figure 26 , Figure 27 As shown.

[0082] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0083] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
