Description

[0001] This application is a divisional application of Chinese Patent Application No. 202311371255.4, entitled "An Integrated Water Tank and Cleaning Device", filed on October 21, 2023, the contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of cleaning equipment technology, and in particular to an integrated water tank for a floor scrubber. Background Technology

[0003] A floor scrubber is a cleaning machine suitable for cleaning hard floors while simultaneously vacuuming up and removing wastewater from the site. It consists of a handheld unit and a cleaning head. When the floor scrubber is in operation, the cleaning head is moved using the handheld unit to remove debris from the floor.

[0004] Typically, floor scrubbers have separate clean water and wastewater tanks. The clean water tank is located in the handheld part, while the wastewater tank is located in the cleaning head. Specifically, the clean water tank is usually located in the body of the handheld part, and the water electrolysis device and water pump that work in conjunction with the clean water tank are located in the tank body. The water pump delivers clean water or electrolyzed water to the cleaning head for cleaning, and the wastewater after cleaning is finally recycled to the wastewater tank. Summary of the Invention

[0005] The inventors discovered that in existing technologies, the water tanks in cleaning devices are typically vertical tanks mounted on the device itself. These tanks usually lack a wastewater level detection device or mechanism, making it difficult for users to know whether the clean water has run out or the wastewater is full. This can lead to water shortages and wastewater overflows, re-contaminating the cleaned area and affecting cleaning effectiveness. Even when clean water and / or wastewater level detection devices are installed on the vertical tank, the rapid pushing and pulling of the tank by the user causes the clean water and / or wastewater in the tank to agitate, causing the detection devices to sway within the clean water and / or wastewater chambers. This swaying is particularly problematic when the limiting mechanism of the detection devices aligns with the user's pushing and pulling direction, further impacting the accuracy of the clean water and / or wastewater level detection. Furthermore, existing technologies lack solutions for integrating the clean water chamber and wastewater chamber into a single, horizontally mounted water tank on the main body of the cleaning device, and also lack solutions for horizontally assembling the single-unit water tank onto the cleaning head of the cleaning device. This application provides a single-unit water tank, primarily addressing the issue of easy installation onto the main body of the cleaning device. It also solves the problem of not being able to identify the water levels in the clean water chamber and / or wastewater chamber, and addresses the issue of inaccurate detection of clean water and / or wastewater due to the sloshing of water and wastewater when the user pushes and pulls the floor scrubber.

[0069] In one or more alternative embodiments, a guide portion is provided on the side wall of the water tank body along the length direction, and a corresponding connecting portion is provided on the cleaning device body. The guide portion and the connecting portion are snapped together for installing the integrated water tank into the cleaning device body.

[0070] The beneficial effects of the above-mentioned technical solutions provided in the embodiments of this application include at least the following:

[0071] The integrated water tank provided in this application embodiment, through the inclusion of a locking mechanism, facilitates easy connection and fixation between the integrated water tank and the main body of the cleaning device, making disassembly and installation convenient and simple to operate. When the user needs to remove the integrated water tank, simply apply pressure to the locking mechanism, which is fully accommodated in the receiving portion, thereby releasing the lock and allowing the integrated water tank to be removed from the main body of the cleaning device. When it is necessary to assemble the integrated water tank onto the main body of the cleaning device, the locking mechanism extends to lock the integrated water tank onto the main body of the cleaning device, achieving a stable installation of the integrated water tank through the locking mechanism connection. Simultaneously, since the locking mechanism is located on the end cap assembly, it does not occupy the internal cavity space of the integrated water tank, ensuring the water capacity of the internal cavity.

[0072] The integrated water tank provided in this application divides the tank body into a clean water chamber and a wastewater chamber via a partition. Clean water from the clean water chamber is supplied through a clean water inlet on a sealed bottom cover, while wastewater is collected and temporarily stored in the wastewater chamber through a wastewater inlet on the bottom cover. This design can be applied to cleaning devices employing water-dust circulation technology, including floor scrubbers, to achieve water circulation within the cleaning device. By combining the wastewater and clean water chambers into a single tank body, it simultaneously provides clean water and collects wastewater, achieving an integrated tank design that significantly reduces tank size, facilitates miniaturization of the cleaning device, and makes it more convenient to use.

[0073] The integrated water tank provided in this embodiment has a bottom cover assembly sealed to the tank body. A float and Hall effect sensor, sandwiched between the bottom cover assembly and the bottom of the tank body, detect the water level in the clean water chamber and the wastewater chamber. Specifically, the float rotates under buoyancy; the greater the buoyancy, the greater the amplitude of the float's rotation. The distance between the Hall effect sensor or sensing element inside the float and the external environment changes accordingly, altering the sensing intensity. This changes the water level in the wastewater chamber, allowing users to promptly know the water levels in both chambers and preventing water shortages in the clean water chamber and wastewater overflows from the wastewater chamber. The float support rod of the provided embodiment rotates in the same direction as the user pushes and pulls the cleaning device. This prevents the sloshing of clean and wastewater in the chambers caused by the user pushing and pulling the floor scrubber from affecting the rotation direction of the float support rod, and also solves the problem of low accuracy in clean and wastewater detection due to sloshing when the user pushes and pulls the cleaning device.

To simplify the disclosure, specific examples of components and arrangements are described herein. These are merely examples and are not intended to limit the invention.

[0116] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0117] The following will describe the scheme of this application in detail with reference to the accompanying drawings.

[0118] Firstly, such as Figures 1-19 As shown, this application provides an integrated water tank 1, installed on the body 2 of a cleaning device, to provide clean water for the cleaning device and collect wastewater. The integrated water tank includes a tank body 10, an end cap assembly 20, a bottom cap assembly 30, and a water level detection element 305. The tank body 10 has an open end 102 and a bottom end 101, and includes a clean water chamber 11 and a wastewater chamber 12 separated by a partition 10c. The end cap assembly 20 closes the open end 102, and the end cap assembly 20 can be mounted on the top wall of the cleaning device body 2 (see attached figure). (Not shown) Inner snap-fit; The bottom cover assembly 30 includes a bottom cover 301, which is detachably connected to the bottom end 101 and docks with one side wall of the cleaning device body 2 (not shown in the figure); A water level detection element 305 is provided between the bottom cover 301 and the bottom end 101 to enclose a receiving chamber 101h that communicates with the water tank body 10, so as to indicate the water level in the receiving chamber; The end cover assembly 20, the water tank body 10, and the bottom cover assembly 30 are sequentially and sealed together to form a whole, which is convenient for users to install and maintain.

[0119] The integrated water tank provided in this application embodiment is secured to the inner side of the top wall of the cleaning device body via an end cap assembly. This facilitates insertion and removal of the integrated water tank from the cleaning device body, making disassembly and installation simple. When the user needs to remove the integrated water tank, simply release the end cap assembly from the inner side of the top wall of the cleaning device body to remove the integrated water tank. When the user needs to assemble the integrated water tank onto the cleaning device body, the end cap assembly locks the integrated water tank to the cleaning device body, securely engaging with the inner side of the top wall of the cleaning device body. Simultaneously, the end cap assembly does not occupy the internal cavity space of the integrated water tank, ensuring the water capacity of the integrated water tank's internal cavity.

[0120] Specifically, in this embodiment, such as Figures 2 to 4 , Figure 10 As shown, the integrated water tank 1 has an open end 102 and a bottom end 101; the water tank body 10 includes a clear water chamber 11 and a wastewater chamber 12 separated by a partition 10c; an end cap assembly 20 closes the open end 102; the bottom cap assembly 30 includes a bottom cap 301, which is detachably connected to the bottom end 101; as shown Figure 1 As shown, when the user installs the integrated water tank 1 onto the cleaning device body 2, the end cap assembly 20 can be snapped into the inner side of one top wall of the cleaning device body 2; the bottom cover 301 abuts against one side wall of the cleaning device body 2; as shown Figure 6 , Figure 9 , Figure 11 , Figure 12 As shown, the bottom of the water tank body 10 is provided with a receiving chamber 101h. The bottom cover 301 covers one end opening of the receiving chamber 101h. A water level detection element 305 is disposed in the receiving chamber 101h enclosed between the bottom cover 301 and the bottom 101 to indicate the water level in the receiving chamber. The receiving chamber 101h provides ample space for the water level detection element 305 to float upwards, making it less likely for the water level detection element 305 to be stuck at the bottom of the water tank body 10. This allows the water level detection element 305 to respond promptly to changes in the water level in the receiving chamber under the action of buoyancy.

[0121] In an alternative embodiment, such as Figure 7 and Figure 9 As shown, the containment chamber 101h is connected to the sewage chamber 12. When the sewage level in the containment chamber changes, the water level detection element 305 can respond to the change in sewage level in a timely manner under the action of buoyancy. This embodiment can be used to accurately detect the change in sewage level in the sewage chamber.

[0122] In an optional embodiment, the receiving chamber 101h is connected to the clear water chamber 11. When the clear water level in the receiving chamber changes, the water level detection element 305 can respond to the change in the clear water level in a timely manner under the action of buoyancy. This embodiment can be used to accurately detect the change in the clear water level in the clear water chamber.

[0123] In an optional embodiment, the bottom of the water tank body 10 is provided with two receiving chambers, each containing a water level detection device. One receiving chamber is connected to the sewage chamber 12, and the other receiving chamber is connected to the clean water chamber 11. When the sewage or clean water level in each of the receiving chambers changes, the water level detection device can respond promptly to the change in sewage or clean water level under the action of buoyancy. This embodiment can be used to accurately detect the sewage level changes in the sewage chamber and the clean water chamber.

[0124] Specifically, in this embodiment, such as Figures 2 to 4 , Figure 7 , Figure 10 As shown, the water tank body 10 is cylindrical, with one end being an open end 102 and the other end being a bottom end 101. A partition 10c is installed inside the water tank body 10, running along the length of the water tank body 10 within a semi-enclosed cavity, dividing the water tank body 10 into a clean water cavity 11 and a wastewater cavity 12. Specifically, as... Figure 7 , Figure 10 As shown, the clear water chamber 11 is located above the partition 10c, and the wastewater chamber 12 is located below the partition 10c. Figure 7 As shown, the bottom 101 of the water tank body 10 is provided with a sewage inlet 101e and a clean water outlet 101d that can be sealed. The sewage inlet 101e is located above the clean water outlet 101d, and the sewage inlet 101e is connected to the sewage chamber 12, while the clean water outlet 101d is connected to the clean water chamber 11.

[0125] Furthermore, refer to Figures 2 to 4 As shown, the integrated water tank includes an end cap assembly 20 located at the open end 102 of the water tank body 10 and a bottom cap assembly 30 located at the bottom end 101 of the water tank body 10. In actual use, the bottom cap assembly 30 seals the bottom end 101 of the water tank body 10, allowing the water tank body 10 to exchange water with the outside environment only through the sewage inlet 101e and the clean water outlet 101d. Clean water from the clean water chamber 11 is supplied to the outside through the clean water outlet 101d, and sewage is recycled to the sewage chamber 12 through the sewage inlet 101e. The end cap assembly 20 closes the open end 102. By removing the part of the end cap assembly 20 used to seal the sewage chamber 12, the sewage in the sewage chamber 12 can be poured out.

[0126] In an optional embodiment, refer to Figure 6 and Figure 7The bottom end 101 is provided with a first mounting cavity (not shown in the attached drawing) and a second mounting cavity (not shown in the attached drawing). The first mounting cavity is used to accommodate the sewage inlet closure (not shown in the attached drawing), and the second mounting cavity is used to accommodate the clean water outlet closure (not shown in the attached drawing).

[0127] In actual use, the connection between the sewage chamber 12 and the outside world is controlled by adjusting the position of the sewage inlet seal in the first installation cavity.

[0128] Specifically, refer to Figure 6 and Figure 7 The sewage inlet closure can be any of a push-button valve, a rotary valve, or a sliding valve, as long as it can control the connection between the sewage inlet 101e and the sewage chamber 12. In this embodiment, the bottom of the first mounting cavity is the sewage inlet closure abutment wall 10d. The sewage inlet closure includes a sewage valve core 304 and a sewage valve core spring 307. One end of the sewage valve core spring 307 is connected to the sewage inlet closure abutment wall 10d, and the other end is connected to the sewage valve core 304. In the initial sealed state, the outer wall of the sewage valve core 304 is pressed tightly against the periphery of the sewage inlet 101e to seal the sewage inlet. When sewage needs to be recycled, the sewage valve core 304 moves toward the sewage inlet closure abutment wall 10d, squeezing the sewage valve core spring 307, so that the sewage chamber 12 is connected to the sewage channel (not shown in the figure) through the sewage inlet 101e, and the sewage enters the sewage chamber 12 through the sewage inlet 101e.

[0129] Accordingly, in this embodiment, during actual use, the position of the clean water outlet seal in the second mounting cavity is adjusted to control the connection between the clean water cavity 11 and the outside.

[0130] Specifically, refer to Figure 6 and Figure 7 The clean water outlet closure can be any of a push-button valve, a rotary valve, or a sliding valve, as long as it can control the connection between the clean water outlet 101d and the clean water chamber 11. In this embodiment, the bottom of the second mounting chamber is the clean water outlet closure abutment wall 10e. The clean water outlet closure includes a clean water valve core 303 and a clean water valve core spring 306. One end of the clean water valve core spring 306 is connected to the clean water outlet closure abutment wall 10e, and the other end is connected to the clean water valve core 303. In the initial sealed state, the outer wall of the water valve core 303 is pressed tightly against the periphery of the water outlet 101d to seal the water outlet 101d; when it is necessary to supply water to the outside, the water valve core 303 moves toward the water outlet sealing member abutment wall 10e, compressing the water valve core spring 306, so that the water chamber 11 is connected to the water channel (not shown in the attached figure) through the water outlet 101d, and the water in the water chamber 11 flows out through the water outlet 101d.

[0131] It should be noted that during the cleaning process of assembling the integrated water tank 1 onto the cleaning device body 2, the driving force of the clean water valve core 303 and the sewage valve core 304 comes from the clean water outlet protrusion (not shown in the attached figure) and the sewage outlet protrusion (not shown in the attached figure) on one side wall of the corresponding cleaning device body.

[0132] Furthermore, in an optional embodiment, refer to Figure 4 , Figure 6 , Figure 7 In an optional embodiment, the first mounting cavity is located above the second mounting cavity. Specifically, the center points of the first and second mounting cavities are aligned vertically. This ensures that at least a portion of the first mounting cavity is located above the partition 10c, facilitating the smooth introduction of most of the wastewater into the wastewater chamber 12. Specifically, most of the first mounting cavity is located above the partition 10c, allowing for better utilization of the potential energy difference between the space above the partition 10c and the wastewater chamber 12, enabling wastewater to automatically flow from the wastewater inlet 101e to the wastewater chamber 12.

[0133] It should be noted that the first installation chamber can also be entirely located above the partition 10c. When using the floor scrubber, the user may cause the sewage in the sewage chamber 12 to agitate due to the rapid dragging of the scrubber head. Since the first installation chamber 10h is higher than the partition 10c, the highest point of the sewage agitation can only reach the lower surface of the partition 10c. The agitated sewage needs to continue to cross the height difference between the lowest point of the first installation chamber and the partition 10c before it can be backflowed into the sewage inlet 101e. This can further prevent sewage from backflowing into the first installation chamber 10h and then leaking onto the ground through the sewage inlet 101e, thereby improving the user experience and cleaning efficiency.

[0134] Furthermore, in an optional embodiment, refer to Figure 7 As shown, at least a portion of the second mounting cavity is located below the partition 10c, facilitating the smooth discharge of clean water from the clean water cavity 11 to the outside of the water tank body 10 via the clean water outlet 101d. The entire second mounting cavity may also be located below the partition 10c. The bottom end 101 has a clean water pre-introduction area 101f and a clean water flow channel 101g for connecting the clean water cavity 11 to the clean water outlet 101d. Specifically, refer to... Figure 11 As shown, the pre-introduced water zone 101f is recessed into the cavity of the water tank body 10 and communicates with the water cavity 11. The outlet of the pre-introduced water zone 101f is further connected to the second installation cavity through the water flow channel 101g.

[0135] It should be noted that, referring to Figure 11As shown, the opening height of the pre-introducing water zone 101f is level with or slightly lower than the height of the water chamber 11, and further higher than the opening height of the second mounting cavity. This makes the end of the water channel 101g near the pre-introducing water zone 101f higher than the end near the second mounting cavity. By setting the pre-introducing water zone 101f and the water channel 101g, during the cleaning process when the integrated water tank using the water tank body 10 is assembled into the cleaning device, when the liquid level in the water chamber 11 reaches its lowest point, a portion of water can still be retained in the pre-introducing water zone 101f and the water channel 101g. Even if the water chamber 11 cannot be replenished in time, the portion of water retained in the pre-introducing water zone 101f and the water channel 101g can still supply the cleaning device for a period of time to ensure work efficiency.

[0136] In an optional embodiment, refer to Figure 6 The bottom chamber 101h is designated as a wastewater level detection area, which is connected to the wastewater cavity 12. This wastewater level detection area is used to install level detection devices, which can be any type such as a float, piezoresistive level gauge, or ultrasonic level gauge. Figure 9 As shown, the wastewater level detection area includes a vertical isolation wall 10f and a horizontal isolation wall 10g. The lower end of the vertical isolation wall 10f is connected to the end of the partition plate 10c. The horizontal isolation wall 10g is arranged horizontally, with one end connected to the upper end of the vertical isolation wall 10f and the other end connected to the water tank body 10. The horizontal isolation wall 10g and the vertical isolation wall 10f enclose the wastewater level detection area, making the top height of the wastewater level detection area 101h higher than that of the partition plate 10c, so that the water level detection element can swing normally.

[0137] In an alternative embodiment, specifically, refer to Figure 6 , Figure 7 , Figure 9 , Figure 11 , Figure 12 In this embodiment, the water level detection component 305 can specifically be a float 305. The float is hinged to the connection between the vertical isolation wall 10f and the partition 10c via a float support rod 3051. A Hall sensor 3052 is installed inside the float 305 to sense the magnetic component and thus detect the water level in the sewage chamber 12. When the water level in the sewage chamber 12 is normal, the float 305 is in its initial state. As the water level in the sewage chamber 12 rises, the float swings upward under the action of buoyancy until it contacts the bottom of the horizontal isolation wall 10g, at which point a water level warning is issued. Because the sewage will first hit the float during the rise in water level, causing the float to swing upward and contact the horizontal isolation wall 10g, the liquid in the sewage chamber 12 has not yet reached the partition 10c. Therefore, even if the sewage in the sewage chamber 12 is not discharged in time, there is still a reserve in the sewage chamber 12 to accommodate a portion of the sewage.

[0138] The working principle of this embodiment is as follows: (See reference) Figure 9 When the water level in the sewage chamber 12 is normal, the float 305 is in its initial state. As the volume of sewage collected in the sewage chamber 12 increases, the water level in the sewage chamber 12 gradually rises. Under the action of buoyancy, the float continues to swing upward, and the sensing intensity between the Hall sensor 3052 and the sensing element gradually increases until the float 305 swings to the warning water level. At this time, the sensing intensity reaches the warning sensing intensity. The control device set outside the bottom cover assembly 30 senses this warning sensing intensity and notifies the user through the response alarm, thereby providing a warning about the water level. At this time, the water level in the sewage chamber 12 has not yet reached the maximum water level. The water level in the sewage chamber 12 continues to rise, and the float continues to swing upward until it reaches the maximum water level (that is, the amount of sewage in the sewage chamber reaches its maximum value). It is worth noting that the warning water level is lower than the maximum water level. Therefore, when the sewage chamber 12 is almost full, the user will be notified to change the water in time. There is actually still space in the sewage chamber 12 to accommodate some sewage. The sewage chamber 12 continues to suck up sewage until it is full. The time between the alarm response and the water suction equipment stopping is the response time, giving the user sufficient response time to know that the sewage chamber 12 is full.

[0139] In an optional embodiment, the float 305 is equipped with a sensor (not shown in the figure) that matches the Hall sensor, and the bottom cover assembly 30 is equipped with a Hall sensor on the outside. The float 305 is disposed in the receiving chamber 102. Since the receiving chamber 102 is connected to the sewage chamber 12, sewage can enter the receiving chamber 102 and come into contact with the float 305. The float 305 can float under the action of buoyancy. The sensor inside the float 305 senses the Hall sensor on the outside of the bottom cover assembly 30, thereby indicating the water level in the sewage chamber 12. Its working principle is the same as the above-described working principle of indicating the water level in the sewage chamber 12 by setting a Hall sensor 3052 inside the float and sensing the sensor on the outside of the bottom cover assembly 30, and will not be repeated here.

[0140] In an optional embodiment, see Figure 9The float 305 includes a float body (not shown in the figure) and a float support rod 3051 fixedly connected to the float body. The float support rod 3051 has a pin hole, and the inner wall of the receiving chamber 102 has a hinge connection part (not shown in the figure). The pin hole is connected to the hinge connection part via a pin, thus hinged the float support rod 3051 to the receiving chamber 102. This limits the swaying of the float body within the receiving chamber, ensuring that the Hall sensor 3052 always maintains mutual sensing with the sensing element. This prevents the Hall sensor 3052 from losing or weakening its sensing due to excessive swaying of the float body, which would affect the accuracy of water level detection. The float body rotates around the float support rod 3051 under buoyancy. In the figure, the direction of rotation of the float body is up and down. The position of the float body in the figure represents the initial state when there is no sewage in the sewage chamber 12. The more sewage in the sewage chamber 12, the greater the buoyancy force on the float body, and thus the greater the upward rotation amplitude of the float body. As the rotation amplitude of the float body changes, the distance between the Hall sensor 3052 installed inside the float body and the sensing element installed outside the bottom cover assembly 30 changes accordingly, and the sensing intensity between the two also changes, thereby characterizing the water level in the sewage chamber 12.

[0141] In an optional embodiment, see Figure 6 , Figure 9 The axial direction of the rotation axis of the float support rod 3051, which is hinged to the receiving chamber, is parallel to the direction in which the user pushes and pulls the cleaning device. This ensures that the rotation axis direction of the float support rod 3051 is consistent with the direction in which the user pushes and pulls the cleaning device. In other words, the direction of the sloshing of sewage in the sewage chamber 12 caused by the user pushing and pulling the cleaning device is consistent with the rotation axis direction of the float support rod 3051. Therefore, the force generated by the sloshing of sewage is perpendicular to the rotation direction of the float support rod 3051. This means that the float support rod 3051 will only rotate when the float body is subjected to buoyancy, and will not rotate due to the aforementioned force. Therefore, the sloshing of sewage when the user pushes and pulls the cleaning device will not easily affect the rotation of the float support rod 3051, thus improving the accuracy of sewage detection.

[0142] In an alternative embodiment, further refer to Figure 3 , Figure 13The integrated water tank 1 has its water tank body 10 horizontally and detachably connected to the cleaning device body 2. The insertion and removal direction of the water tank body 10 when installed on the cleaning device body 2 is perpendicular to the direction in which the user pushes and pulls the cleaning device (not shown in the figure). This ensures that the rotation axis direction of the float support rod 3051 is consistent with the direction in which the user pushes and pulls the cleaning device. In other words, the direction of the sloshing of sewage in the sewage chamber 12 caused by the user pushing and pulling the cleaning device is consistent with the rotation axis direction of the float support rod 3051. Therefore, the force generated by the sloshing of sewage is perpendicular to the rotation direction of the float support rod 3051. That is, the float support rod 3051 will only rotate when the float body is subjected to buoyancy, and will not rotate due to the aforementioned force. Therefore, the sloshing of sewage when the user pushes and pulls the cleaning device will not easily affect the rotation of the float support rod 3051, which can improve the accuracy of sewage detection.

[0143] It should be noted that a clear water level detection area (not shown in the attached diagram) can also be further provided at the bottom 101 to detect whether the clear water in the clear water chamber 11 has been exhausted. The clear water level detection area is used to install a water level detection device, and the clear water level detection area is connected to the clear water chamber. In this embodiment, the clear water level detection area can be directly opened in the clear water pre-introduction area 101f, or the water level detection device can be directly placed in the clear water pre-introduction area 101f. For specific technical solutions, refer to the scheme where the water level detection device is placed in the sewage level detection area, which will not be repeated here. Of course, two water level detection devices can also be set. The two water level detection devices can be set in the clear water pre-introduction area 101f and the sewage level detection area at the same time. The two water level detection devices are used to determine whether the clear water in the clear water chamber 11 has been exhausted and whether the sewage in the sewage chamber 12 is full of sewage, respectively.

[0144] In an optional embodiment, refer to Figure 11 , Figure 12 A sealing outer edge 101a is provided on the outer periphery of the bottom end 101, extending from the bottom end 101 away from the opening end 102. A sealing inner edge 101b is also provided on the end face of the bottom end 101. The sealing inner edge 101b includes a sewage inlet sealing rib 1012 arranged around the sewage inlet 101e, a clean water outlet sealing rib 1011 arranged around the clean water outlet 101d, a sewage water level detection area sealing rib 1014 arranged around the receiving chamber 101h, and a clean water flow channel sealing rib 1013 arranged around the clean water flow channel 101g and the clean water pre-introduction area 101f. The sewage inlet sealing rib 1012, the clean water outlet sealing rib 1011, the sewage water level detection area sealing rib 1014, and the clean water flow channel sealing rib 1013 all protrude from the bottom end 101 away from the opening end 102, and the protrusion height is the same as that of the sealing outer edge 101a.

[0145] In an optional embodiment, refer to Figure 6 , Figure 9 , Figure 10A water inlet 10b is provided on the side wall of the water tank body 10 near the clear water chamber 11, and the water inlet 10b is connected to the clear water chamber 11. A water inlet cap assembly 103 is provided at the water inlet 10b to close the water inlet 10b.

[0146] In an alternative embodiment, such as Figure 2 , Figure 4 , Figure 6 , Figures 9 to 12 , Figure 19 As shown, to facilitate the filling of the water chamber 11 with clean water, a water inlet 10b is provided on the outer wall of the water chamber 11. Furthermore, to facilitate opening or closing of the water inlet 10b, as shown... Figure 2 As shown, a water inlet cap assembly 10d is provided on the outer wall of the clear water chamber 11. The water inlet cap assembly 10d includes a water inlet cap body, a sealing head, and a one-way valve. One side of the water inlet cap body has a hinge joint, and the water inlet cap body is hinged to the outer wall of the clear water chamber 11 through the hinge joint. The other side of the water inlet cap body has a sealing head, which is engaged with the water inlet 10b. At the same time, in order to ensure the water tightness of the water inlet 10b, a groove is provided on the outer periphery of the sealing head. The sealing element is located in the groove and is embedded between the sealing head and the water inlet 10b to seal the water inlet 10b. The sealing element can be, but is not limited to, an O-ring, a sealing strip, etc. The sealing head is equipped with a one-way valve, which enables one-way communication between the outside and the water chamber 11 to achieve air pressure balance. Since the water in the water chamber 11 is in a closed space for a long time, the temperature inside is often higher than the outside temperature, which makes the air pressure in the water chamber 11 higher than atmospheric pressure. The one-way valve is used to achieve air pressure balance to prevent the air pressure in the water chamber 11 from being too high and pushing the sealing head away from the water inlet 10b.

[0147] Specifically, refer to Figure 9 When opening the water inlet 10b, a placement groove 10j with an upward opening is first provided on the top of the water tank body 10 near the clean water chamber 11. The water inlet 10b is further opened at the bottom of the placement groove 10j, and then the water inlet cap assembly 103 is installed into the placement groove 10j, so that the upper end surface of the water inlet cap assembly 103 is flush with the outer wall surface of the water tank body 10, which facilitates the installation of the water tank body 10 into the corresponding cleaning device.

[0148] Furthermore, in an optional embodiment, the water inlet cap assembly 103 includes a water inlet cap body 1031, a water inlet seal 1032, and a one-way valve 1033. The water inlet cap body 1031 has a hinge joint 1034 on one side, and the water inlet cap body 1031 is hinged to the water tank body 10 via the hinge joint 1034. Figure 11As shown, the bottom of the water inlet cap body 1031 has a locking head 1031a for locking onto the water inlet 10b. A locking groove is formed on the outer peripheral side wall of the locking head 1031a, and a water inlet seal 1032 is located within the groove and embedded between the water inlet cap body 1031 and the water inlet 10b to seal the water inlet 10b. The water inlet seal 1032 can be an O-ring or a sealing strip, etc.

[0149] In an optional embodiment, refer to Figure 10 , Figure 11 The water filling cap body 1031 is provided with an air hole (not shown in the attached diagram). A one-way valve 1033 is specifically provided on the water filling cap body 1031 and communicates with the air hole, so that the outside world and the inside of the clear water chamber 11 can be connected in one direction from the outside to the inside to achieve air pressure balance. Since the water flow in the clear water chamber 11 is large, the water flow is prone to sloshing. The one-way valve 1033 can prevent water droplets in the clear water chamber 11 from splashing out from the air hole. The length of the water filling cap body 1031 is less than the length of the placement groove 10j. Therefore, when the locking head 1031a is locked to the water filling port 10b, there is a gap between the edge of the water filling cap body 1031 and the side wall of the placement groove 10j, so that a person can reach in to open the water filling cap body 1031.

[0150] It should be noted that in other embodiments, the water inlet cap assembly 103 can also be directly snapped onto the water inlet 10b, or other connection methods can be used to cooperate with the water inlet 10b, as long as the purpose of injecting water from the water inlet 10b into the clear water chamber 11 and sealing the water inlet 10b can be achieved.

[0151] In an optional embodiment, refer to Figures 1 to 4 , Figure 10 A guide portion 10a is provided along the length direction of the side wall of the water tank body 10, and a corresponding connecting portion is provided on the cleaning device body 2. The guide portion and the connecting portion are snapped together to install the integrated water tank 1 into the cleaning device body 2, improving installation efficiency. Specifically, the guide portion 10a can be a guide groove 10a provided on the side wall of the water tank body 10. A certain distance can be left between the guide groove and the opening end 102 of the water tank body 10 to limit the position of the water tank body 10 after installation. Alternatively, the guide portion 10a can also be a protrusion provided along the length direction of the water tank body 10, with a corresponding slot provided in the cleaning device, simply to guide the installation of the water tank body 10 and the cleaning device. Figure 2 , Figure 3 , Figure 4 As shown, an example of a guide groove 10a is given, wherein one end of the guide groove 10a is through and the other end is not through, so as to limit the position of the integrated water tank 1 after installation.

[0152] In an optional embodiment, refer to Figure 11 , Figure 12The bottom end 101 faces outward and is provided with multiple nut posts 101c. The nut posts 101c are used to install the bottom cover assembly 30. The number and distribution of the nut posts 101c are not specifically limited, as long as the installation strength is met. Of course, in other embodiments, other connection methods can also be used, such as ultrasonic welding, snap-fit, adhesive bonding, etc.

[0153] In this embodiment, the water tank body 10 is part of the integrated water tank 1. Clean water is injected into the clean water chamber 11 through the water inlet 10b, while the wastewater chamber 12 is used to contain wastewater generated during the cleaning process. After the integrated water tank 1 is installed on the cleaning device body 2, the clean water inlet protrusion (not shown in the figure) of the cleaning device body 2 elastically abuts against the clean water valve core 303, connecting the clean water chamber 11 and the clean water outlet 101d. Clean water flows sequentially from the clean water pre-introduction area 101f, the clean water flow channel 101g, and the clean water outlet 101d to the clean water channel. Similarly, the wastewater inlet protrusion (not shown in the figure) of the cleaning device body elastically abuts against the wastewater valve core 304, connecting the wastewater chamber 12 and the wastewater inlet 101e. Wastewater flows into the wastewater chamber 12 through the wastewater inlet 101e under the action of gravity, thereby realizing water circulation. The water level detection device is located in the receiving chamber 101h and can detect the liquid level in the clean water chamber and / or the wastewater chamber 12. When the liquid level in the sewage chamber 12 reaches the warning height, the user is promptly prompted to remove the integrated water tank 1 and discharge the sewage from the opening end 102; when the liquid level in the clean water chamber 11 reaches the warning height, the user is promptly prompted to remove the integrated water tank 1 and inject clean water into the clean water chamber 11 from the water inlet 10b.

[0154] In an alternative embodiment, such as Figure 2 , Figure 3 As shown, the end cap assembly 20 includes an end cap middle frame 20a, an upper end cap 20b, and a lower end cap 20c. The end cap middle frame 20a is connected to the open end 101, and the upper end cap 20b is detachably connected to the end cap middle frame 20a. It should be noted that the end cap middle frame 20a can be fixedly connected to the open end 101 by ultrasonic welding, bonding, or other methods; the upper end cap 20b can be detachably connected to the end cap middle frame 20a by threaded connection, snap-fit ​​connection, or other methods; the lower end cap 20c is detachably connected to the end cap middle frame 20a; the upper end cap assembly 20b corresponds to the clean water chamber 11, and the lower end cap 20c corresponds to the wastewater chamber 12. The lower end cap 20c can be detachably connected to the upper end cap assembly 20b or directly detachably connected to the end cap middle frame 20a, as long as it allows for removal and installation of the lower end cap 20c from the water tank body 10. Of course, in other embodiments, the upper end cap assembly 20b and the lower end cap 20c may be integrally formed and detachably connected to the water tank body 10.

[0155] Furthermore, in an optional embodiment, such as Figure 18 and Figure 19 As shown, the water tank body 10 is divided into a clean water chamber 11 and a wastewater chamber 12 by a partition 10c. The opening end 102 includes a clean water opening end and a wastewater opening end. A sealing partition 20a1 is provided in the middle of the end cover frame 20a, dividing the end cover frame 20a into upper and lower parts. The upper part of the end cover frame 20a is used to close the clean water opening end, and the lower part of the end cover frame 20a is connected to the wastewater opening end, forming a wastewater pouring port 20a11. The lower end cover 20c can be closed to the wastewater pouring port 20a11. The upper part of the end cover frame 20a forms a closed space for the clean water chamber 11 that is independent of the wastewater chamber 12. This prevents wastewater generated during subsequent cleaning of the wastewater chamber 12 from entering the clean water chamber 11, and also prevents water from the wastewater chamber 12 from mixing into the clean water chamber 11 due to shaking. This ensures the cleanliness of the water in the clean water chamber 11, which is one of the basic conditions for ensuring cleanliness. Meanwhile, by setting a sealing plate 20a1 in the middle of the end cap frame 20a, the structural strength of the end cap frame 20a can be increased, further improving the supporting force of the end cap frame 20a. In addition, the sealing plate 20a1 is fixedly connected to the partition plate 10c by ultrasonic welding, bonding and other methods, which can further make the connection between the end cap frame 20a and the opening end 101 of the water tank body 10 more secure. By setting a lower end cap 20c to cover the sewage pouring port 20a11, the sewage pouring port 20a11 is sealed. When the user needs to clean the sewage, the lower end cap 20c can be removed from the sewage pouring port 20a11, making it convenient for the user to clean the sewage collected in the sewage chamber 12 in a timely manner.

[0156] In an alternative embodiment, such as Figure 7 , Figure 8 , Figure 18 , Figure 19 As shown, the end cap assembly 20 also includes a locking mechanism (not shown in the figure) sandwiched between the end cap middle frame 20a and the upper end cap 20b. A receiving portion (not shown in the figure) is provided between the end cap middle frame 20a and the upper end cap 20b; the locking mechanism is movably disposed in the receiving portion and partially extends out of the upper plane of the end cap middle frame 20a and the upper end cap 20b; the locking mechanism can move under pressure to be fully received in the receiving portion. Because a locking mechanism is provided on the end cap assembly 20, it is convenient for the user to connect and fix the integrated water tank 1 to the body of the cleaning device, facilitating disassembly and installation, and simplifying operation. When the user needs to remove the integrated water tank 1 for cleaning, pressure is applied to the locking mechanism, which is fully received in the receiving portion, thereby releasing the lock and removing the integrated water tank 1 from the body of the cleaning device. When it needs to be reinstalled on the body of the cleaning device, the locking point on the cleaning device body cooperates with the locking mechanism to achieve a stable installation of the integrated water tank 1. Meanwhile, since the locking mechanism is located on the end cap assembly 20, it does not occupy the water cavity portion of the integrated water tank 1, thus ensuring the water capacity of the water cavity.

[0157] Furthermore, in this embodiment, as Figure 7 , Figure 8 , Figure 18 , Figure 19 As shown, the locking mechanism includes a locking tongue 20b2 and an elastic element 20b3; the elastic element 20b3 is disposed between the locking tongue 20b2 and the first limiting plate 20b5; under the elastic force of the elastic element 20b3, the locking tongue 20b2 partially extends out of the opening formed by the first guide groove 20a2 and the second guide groove 20b13; the locking tongue 20b2 can move under pressure, compressing the elastic element 20b3, so that the locking tongue 20b2 is completely accommodated in the accommodating part.

[0158] In an alternative embodiment, such as Figure 18 , Figure 19 As shown, the end cap frame 20a has a first guide groove 20a2, and the upper end cap 20b has a second guide groove 20b13 corresponding to the first guide groove 20a2. The upper end cap 20b has a first limiting plate 20b5 and two parallel second limiting plates 20b6. A receiving portion is formed between the first limiting plate 20b5, the two second limiting plates 20b6, the first guide groove 20a2, and the second guide groove 20b13. The locking mechanism includes a locking tongue 20b2 and an elastic element 20b3. The elastic element 20b3 is disposed between the locking tongue 20b2 and the first limiting plate 20b5. Under the elastic force of the elastic element 20b3, the locking tongue 20b2 partially extends out of the opening formed by the first guide groove 20a2 and the second guide groove 20b13. The locking tongue 20b2 can move under pressure, compressing the elastic element 20b3, so that the locking tongue 20b2 is completely received in the receiving portion.

[0159] Furthermore, in the embodiments of this application, such as Figure 18 , Figure 19 As shown, the locking tongue 20b2 of the locking mechanism is elastically connected to the first limiting plate 20b5 via an elastic element 20b3. Figure 6 As shown, the free state of the elastic element 20b3 is set as follows: the locking tongue 20b2 extends out of the opening formed by the first guide groove 20a2 and the second guide groove 20b13; the compressed state of the elastic element 20b3 is set as follows: the locking tongue 20b2 moves toward the first limiting plate 20b5 and can be completely accommodated in the receiving part. Figure 9 and Figure 10 As shown, the width of the portion of the latch 20b2 extending out of the opening is smaller than the width of the overall latch 20b2, and the width of the portion of the latch 20b2 is smaller than the width of the first guide groove 20a2. When the portion of the latch 20b2 extends out of the opening, the inner wall of the first guide groove 20a2 abuts against the outer wall of the latch 20b2 to limit the latch 20b2 and prevent the latch 20b2 from moving excessively and disengaging from the receiving part.

[0160] Furthermore, in this embodiment, a lock hole (not shown in the figure) is provided on the cleaning device body 2 corresponding to the lock tongue 20b2. When the elastic member 20b3 is in a free state, the lock tongue 20b2 extends out of the opening and engages with the lock hole, thereby fixing the integrated water tank 1 to a top wall (not shown in the figure) of the cleaning device body 2. When pressure is applied to the lock tongue 20b2, the elastic member 20b3 is compressed, and the lock tongue 20b2 moves toward the first limiting plate 20b5 and gradually disengages from the lock hole until the lock tongue 20b2 is completely accommodated in the receiving part. The lock tongue 20b2 is then unlocked from the lock hole, allowing the integrated water tank 1 to be easily disassembled from the cleaning device body. By sliding the lock tongue 20b2 relative to the first limiting plate 20b5, the lock tongue 20b2 can be switched between the unlocked and locked states. The structure is simple and easy to operate, facilitating the disassembly of the integrated water tank 1 and the cleaning device body 2 while improving the reliability of the connection between the two.

[0161] In an alternative embodiment, such as Figure 18 As shown, the latch 20b2 includes a latch body 20b21 and a pressing part 20b22, and the upper end cover 20b has a pressing opening 20b12 corresponding to the position of the pressing part 20b22.

[0162] Furthermore, in this embodiment, as Figure 18 As shown, the latch body 20b21 and the pressing part 20b22 can be formed as follows: Figure 18 The L-shape shown can also be formed into other shapes found in the prior art, and is not limited thereto. A pressing port 20b12 is provided on the upper end cover 20b at a position corresponding to the pressing part 20b22. The user can contact and press the pressing part 20b22 through the pressing port 20b12 to overcome the elastic force of the elastic member 20b3, causing the latch body 20b21 to move away from the keyhole, thereby unlocking the device. The pressing part 20b22 is located inside the upper end cover 20b to prevent unauthorized unlocking of the latch body 20b21 due to non-human touch, thus improving the reliability of the engagement between the integrated water tank 1 and the cleaning device body 2.

[0163] Furthermore, in this embodiment, as Figure 18 , Figure 19 As shown, the elastic element 20b3 includes a spring, and a limiting part (not shown in the figure) is provided on the pressing part 20b22. One end of the spring is accommodated in and abuts against the limiting part, and the other end of the spring elastically abuts against the first limiting plate 20b5. When the spring is stretched or deformed, one end of the spring is always accommodated in the limiting part, thereby ensuring that the deformation direction of the spring is always consistent with the movement direction of the latch body 20b21. Here, the limiting part can play a certain limiting role for the spring, avoiding the spring from being misaligned under elastic force, which would cause the deformation direction to be inconsistent with the movement direction, resulting in the spring being unable to provide or only providing a portion of the elastic force for the movement of the latch body 20b21.

[0164] In an alternative embodiment, such as Figure 8 , Figure 18 , Figure 19 As shown, at least one fixing post 20a3 extends outward from the upper outward-facing end face of the end cap frame 20a. The end cap frame 20a can be detachably connected to the upper end cap 20b via a snap-fit ​​(not shown in the figure) at the free end of the at least one fixing post 20a3 and a first threaded hole (not shown in the figure). A second through hole 20b11 is provided at the position corresponding to the first threaded hole on the upper end cap 20b, and the first threaded hole and the second through hole 20b11 are connected by screws.

[0165] Furthermore, the second through hole 20b11 can also have internal threads.

[0166] In an alternative embodiment, such as Figure 18 As shown, four symmetrically arranged fixing posts 20a3 are preferably used, and the upper end cover 20b is fixed to the middle frame 20a of the end cover with screws. The connection between the upper end cover 20b and the middle frame 20a of the end cover is reliable and convenient, so that the lock tongue 20b2 is not easy to slip off from the receiving part, thereby making the connection between the lock tongue 20b2 and the lock hole stable and not easy to fall off.

[0167] Furthermore, in this embodiment, as Figure 8 , Figure 18 , Figure 19 As shown, the upper end cover 20b has a fixing hole on its peripheral wall corresponding to the second through hole 20b11. A screw can be used to connect the first threaded hole and the second through hole 20b11 within the fixing hole, achieving a detachable connection between the end cover middle frame 20a and the upper end cover 20b. Furthermore, a fixing hole plug 20b4 can be provided within the fixing hole. After the connection between the end cover middle frame 20a and the upper end cover 20b is secured with screws, the fixing hole is pressed down by the fixing hole plug 20b4. This not only hides the fixing screws, thus improving the appearance of the entire end cover assembly 20, but also prevents water and dust from falling into the fixing hole and affecting subsequent maintenance of the end cover assembly 20.

[0168] In an alternative embodiment, such as Figure 7 , Figure 8 , Figure 18 , Figure 19 As shown, the lower end cover 20c includes a lower end cover body 20c1 and a sealing part 20c12, and the sealing part 20c12 is sealed to the sewage pouring port 20a11.

[0169] Furthermore, in an optional embodiment, such as Figure 7 , Figure 8 , Figure 18 , Figure 19As shown, when the lower end cap 20c is closed with the middle frame 20a, the bottom end face of the lower end cap body 20c1 abuts against the upper end face of the middle frame 20a. At the same time, the sealing part 20c12 is sealed to the sewage pouring port 20a11 to prevent sewage from overflowing.

[0170] In an alternative embodiment, such as Figure 7 , Figure 8 , Figure 18 , Figure 19 As shown, the lower end cover body 20c1 includes a base plate and an outer connecting plate (not shown in the figure), and multiple sets of reinforcing ribs (not shown in the figure) are arranged between the base plate and the outer connecting plate.

[0171] In an alternative embodiment, such as Figure 18 , Figure 19 As shown, the extension connecting plate is provided with a weight-reducing blind hole 20c13.

[0172] In this embodiment of the application, in order to further reduce weight, such as Figure 18 , Figure 19 As shown, the two ends of the extension connecting plate are symmetrically provided with weight reduction blind holes 20c13.

[0173] In an alternative embodiment, such as Figure 18 , Figure 19 As shown, the outer side wall of the extension connecting plate is provided with a gripping part 20c11.

[0174] In this embodiment, the outer side wall of the extension connecting plate is provided with a gripping portion 20c11. The shape and structure of the gripping portion 20c11 are not limited to various ergonomic shapes and structures in the prior art, such as... Figure 18 , Figure 19 As shown, the grip portion 20c11 is preferably symmetrically arranged on the outer side wall of the extension connecting plate. The grip portion 20c11 is a groove, which not only makes it easy for the user to grip, but also reduces the weight of the overall end cap assembly 20.

[0175] In an alternative embodiment, such as Figure 7 , Figure 8 , Figure 18 , Figure 19 As shown, the lower end cover 20c also includes a sealing ring 20c2, which is sleeved on the outer periphery of the sealing part 20c12.

[0176] Furthermore, in this embodiment, the sealing ring 20c2 is made of a flexible material with a certain degree of elasticity. The outer diameter of the sealing ring 20c2 is smaller than the outer diameter of the sealing part 20c12, so that when the sealing ring 20c2 is fitted onto the sealing part 20c12, it is always subjected to elastic force and is tightly connected to the sealing part 20c12, making it difficult to fall off.

[0177] Furthermore, in this embodiment, a snap-fit ​​groove or snap-fit ​​protrusion is provided on the outer periphery of the sealing part 20c12. Correspondingly, a snap-fit ​​protrusion or snap-fit ​​groove is provided on the periphery of the inner wall of the sewage pouring port 20a11, so that the lower end cover 20c is not easy to fall off when it is closed on the sewage pouring port 20a1.

[0178] In an optional embodiment, refer to Figure 6 , Figure 11 , Figure 12 The bottom cover assembly 30 includes a sealing gasket 302 and a bottom cover 301. The sealing gasket 302 is fitted between the sealing outer edge 101a and the sealing inner edge 101b. The sealing gasket 302 has holes corresponding to the sewage inlet 101e and the clean water outlet 101d, respectively, and sealing protrusions corresponding to the clean water pre-introduction area 101f and the clean water flow channel 101g. This allows the clean water outlet 101d and the sewage inlet 101e to communicate with the outside, while other areas are sealed. Furthermore, the sealing gasket 302 can be made of silicone or rubber, as long as it can achieve the sealing function. In the integrated water tank 1, a sealing gasket 302 is further provided at the bottom end 101 of the water tank body 10, thereby fitting between the sealing outer edge 101a and the sealing inner edge 101b to seal the bottom end 101 and prevent water leakage. Meanwhile, the sewage inlet 101e and the clean water outlet 101d are also separated by the corresponding sewage inlet sealing rib 1012 and clean water outlet sealing rib 1011 to avoid the mixing of clean water and sewage.

[0179] Furthermore, in this embodiment, the bottom cover 301 has openings at positions corresponding to the clean water outlet 101d and the sewage inlet 101e, while other parts are closed, further improving the sealing performance. The bottom cover 301 has multiple nut holes corresponding to the nut post 101c, thereby connecting to the bottom end 101 of the water tank body 10.

[0180] In an optional embodiment, see Figure 6 , Figure 11 , Figure 12 , Figure 13 The bottom 101 of the water tank body 10 is also provided with a first receiving chamber communicating with the clean water chamber 11 and a second receiving chamber communicating with the wastewater chamber 12; the bottom cover 301 is provided with a clean water outlet 3011 and a wastewater outlet 3012 respectively. The clean water in the clean water chamber 11 flows from the first receiving chamber to the clean water outlet 3011 and then to the clean water channel provided outside the bottom cover assembly 30 for cleaning the roller. The cleaned wastewater flows from the wastewater outlet 3012 to the second receiving chamber and then enters the wastewater chamber 12 for collection.

[0181] The working principle of this embodiment is as follows: The bottom cover assembly 30 is installed on the water tank body 10, and the integrated water tank 1 is installed on the cleaning device body 2. The clean water inlet protrusion (not shown in the figure) of the cleaning device body 2 elastically abuts against the clean water valve core 303 inward, causing the clean water valve core 303 to move away from the clean water inlet 3011, thereby opening the clean water inlet 3011 and connecting the clean water inlet 3011 with the clean water chamber 11. Clean water flows sequentially from the clean water pre-introduction area 101f, the clean water flow channel 101g, and the clean water inlet 3011 to the clean water channel provided on the cleaning device body, providing clean water for cleaning. Similarly, the sewage outlet protrusion (not shown in the figure) of the cleaning device body 2 elastically abuts against the sewage valve core 304 inward, connecting the sewage chamber 12 and the sewage inlet 3012. The sewage generated during cleaning by the cleaning device flows from the sewage inlet 3012 into the sewage chamber 12 for collection, thereby realizing water circulation during cleaning.

[0182] In an optional embodiment, to further ensure watertightness, refer to Figure 6 , Figure 11 , Figure 12 The sealing gasket 302 is located between the bottom end 101 of the water tank body and the bottom cover 301. The sealing gasket 302 has a clean water outlet 3021 and a wastewater inlet 3022 corresponding to the clean water outlet 3011 and wastewater outlet 3012, respectively, to ensure the outflow of clean water and the inflow of wastewater. The sealing gasket 302 is equipped with a float zone sealing ring 30241, a clean water outlet sealing ring 30211, a wastewater inlet sealing ring 30221, and a central sealing protrusion 3025.

[0183] Specifically, see Figure 14 , Figure 15 , Figure 17 The sealing gasket 302 has a float area opening 3024 corresponding to the receiving chamber 101h. A float area sealing ring 30241 is provided along the outer periphery of the float area opening 3024 on the sealing gasket 302. Multiple layers of first sealing connections are provided on the float area sealing ring 30241. The float area sealing ring 30241 is tightly connected to the inner wall of the receiving chamber 102 through the first sealing connections, ensuring the airtightness of the receiving chamber 102 and preventing water in the sewage chamber 12 from overflowing from the opening end of the receiving chamber 101h. The number and distribution density of the first sealing connections can be adjusted accordingly for different sealing performance requirements. Of course, the number of layers of the first sealing connections should not affect the normal floating of the float 305.

[0184] Similarly, see Figure 14The sealing gasket 302 is also equipped with a clean water outlet sealing ring 30211. The clean water outlet sealing ring 30211 is located between the clean water outlet sealing rib 1011 and the clean water outlet reinforcing rib 30111. The clean water outlet sealing ring 30211 has multiple layers of second sealing connections. The clean water outlet sealing ring 30211 is tightly connected to the inner wall of the first receiving chamber through the second sealing connections to prevent clean water from overflowing and ensure airtightness. At the same time, it also prevents sewage from flowing into the clean water cavity 11 and contaminating the clean water, thus affecting the cleaning effect of subsequent cleaning work. If different sealing performance requirements are required, the number of layers and the distribution density of the second sealing connections can be adjusted accordingly. Of course, the number of layers of the second sealing connections should not affect the sealing of the clean water outlet 3011 by the clean water valve core 303.

[0185] Furthermore, the water outlet sealing ring 30211 is provided with a first protrusion (not shown in the attached figure), and a first recess (not shown in the attached figure) is provided on the sealing surface of the water valve core 303 corresponding to the first protrusion. When the sealing gasket 302 seals the first receiving chamber, the first elastic member 306 is in a pre-compressed state, and the first protrusion is always engaged with the first recess. Thus, the sealing gasket 302 confines the water valve core 303 within the first receiving chamber, preventing the water valve core 303 from being ejected from the first receiving chamber under the force of the first elastic member 306 and losing its function of sealing the water outlet 3011, thereby preventing water from overflowing and ensuring the watertightness of the water outlet 3011.

[0186] Similarly, see Figure 14 The sealing gasket 302 is also equipped with a sewage inlet sealing ring 30221, which is located between the sewage inlet sealing rib 1012 and the sewage inlet reinforcing rib 30121. The sewage inlet sealing ring 30221 has multiple layers of third sealing connections. The sewage inlet sealing ring 30221 is tightly connected to the inner wall of the second receiving chamber through the third sealing connections to ensure airtightness and prevent sewage overflow, which would compromise cleanliness. The number and distribution density of the third sealing connections can be adjusted accordingly for different sealing performance requirements. Of course, the number of layers of the third sealing connections should not affect the sewage valve core 304's ability to seal the sewage outlet 3012.

[0187] Further, see Figure 2 The sewage outlet sealing ring 30211 is provided with a second protrusion (not shown in the attached figure), and a second recess (not shown in the attached figure) is provided on the sealing surface of the sewage valve core 304. The second protrusion can be engaged with the second recess, and its function is the same as that of the first protrusion and the first recess mentioned above. It will not be elaborated here. It can prevent sewage from overflowing and ensure the water tightness of the sewage outlet 3012.

[0188] See Figures 14 to 17The sealing gasket 302 also has a protruding central sealing protrusion 3025, which forms a certain receiving space. The bottom cover 301 has a central abutment rib 3014 corresponding to the central sealing protrusion 3025. The central abutment rib 3014 is received in the central sealing protrusion 3025 and abuts against it. This can further restrict the position of the sealing gasket 302 between the bottom cover 301 and the bottom end of the water tank body 10, preventing the sealing gasket 302 from being misaligned and losing its sealing effect. This prevents sewage from overflowing from the receiving chamber 102 or sewage chamber 12, which could contaminate or even corrode the various components in the end cover assembly 20 and also damage the cleanliness. It also further prevents the leakage of clean water in the clean water chamber 11, which would waste water. At the same time, it prevents sewage from flowing into the clean water chamber 11 and contaminating the clean water, which would affect the cleaning effect of subsequent cleaning work.

[0189] The implementation principle of the integrated water tank 1 in this embodiment is as follows: The integrated water tank 1 is used in conjunction with the cleaning device. The water pumping device of the cleaning device is connected to the clean water valve core 303. The water pumping device pushes the clean water valve core 303 to draw clean water from the clean water chamber 11 to the clean water outlet 3011 to provide clean water for cleaning. The water suction device of the cleaning device is connected to the sewage valve core 304. The water suction device pushes the sewage valve core 304 to draw the sewage generated during cleaning into the sewage chamber 12 through the sewage outlet 3012 for collection. The cleaning device is equipped with a Hall sensor 3052 or a sensing element of the Hall sensor 3052, which can sense each other with the float 305. When the float 305 rotates under the action of buoyancy, the water level is detected. When the sewage chamber 12 is full, the cleaning device promptly informs the user and opens the end cover assembly 20 to clean the sewage in time.

[0190] Secondly, based on the same inventive concept, this application also proposes a cleaning device, including a cleaning device body 2 and an integrated water tank 1 as described in the first aspect. The integrated water tank 1 can be directly snapped onto one side wall of the cleaning device body 2 via the guide portion 10a, or it can be combined with the device in other detachable ways.

[0191] In this embodiment, the cleaning device may further include a cleaning component, a control component, a power supply component, and a main body. The locking mechanism of the integrated water tank 1 is located on the top side of the integrated water tank 1 facing the top wall of the cleaning device main body 2. The integrated water tank 1 is detachably connected to the cleaning device main body 2 through the locking mechanism. The cleaning component is installed on the cleaning device main body 2, and the integrated water tank 1 is in communication with the cleaning component. The power supply component is installed on the cleaning device main body 2 and is connected to the cleaning component to provide kinetic energy to the cleaning component. The control component is installed on the cleaning device main body 2 and is connected to the cleaning component to control the movement of the cleaning component.

[0192] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. Furthermore, any changes or modifications made by those skilled in the art based on the ideas of this application, and on the specific implementation methods and application scope of this application, are all within the scope of protection of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
