Description

Technical Field

[0001] The present disclosure relates to a surface cleaning apparatus. Background Art

[0002] Surface cleaning equipment is suitable for cleaning hard floor surfaces such as tiles, hardwood floors and soft carpet surfaces.

[0003] When the surface cleaning device cleans the surface to be cleaned, the cleaning liquid is first transported to the cleaning module, and the cleaning liquid is applied to the surface to be cleaned by the cleaning module. When the cleaning module and the surface to be cleaned move relative to each other, the surface to be cleaned is cleaned. In the dry cleaning method, the garbage is sucked in by the cooperation of the roller brush and the suction port.

[0004] However, when the surface cleaning device in the prior art cleans a location close to a wall, taking into account the structure of the cleaning base, there is a preset distance between the edge of the roller brush and the wall. Therefore, in edge cleaning, the cleaning effect is poor; and during maintenance, the cleaning components of the surface cleaning device in the prior art are difficult to remove from the surface cleaning device. Summary of the invention

[0005] In order to solve one of the above technical problems, the present disclosure provides a surface cleaning device.

[0029] The present disclosure is further described in detail below in conjunction with the accompanying drawings and implementations. It is understood that the specific implementations described herein are only used to explain the relevant content, rather than to limit the present disclosure. It should also be noted that, for ease of description, only the parts related to the present disclosure are shown in the accompanying drawings.

[0030] Figure 1 A schematic diagram showing an angled view of the surface cleaning device is shown. Figure 2 A schematic diagram showing the surface cleaning device viewed from another angle is shown. Figure 3 An exploded view of the surface cleaning apparatus is shown.

[0031] like Figures 1 to 3 As shown, the surface cleaning device may include a handle portion 100 , a body portion 200 , a cleaning liquid storage portion 300 , a recovery storage portion 400 , a connection portion 500 , and a cleaning base 600 .

[0032] The handle portion 100 may include a grip portion 110 and a connecting rod 120. The grip portion 110 is provided for a user to hold in order to operate the surface cleaning device.

[0033] A control unit 111 may be provided on the handle portion 110 , through which the user may control the surface cleaning device. The control unit 111 may be in the form of a control button, a touch button, etc. A plurality of control units 111 may be provided on the handle portion 110 to perform various controls on the surface cleaning device.

[0034] The control unit 111 can be arranged in the accommodation space provided by the handle portion 110, and, for example, in the case of a control button, the control unit 111 can move relative to the surface of the handle portion 110 so as to turn on or off the corresponding operation. The surface of the control unit 110 can be arranged to be recessed relative to the outer contour surface of the handle portion 110, that is, the surface of the control unit 110 can be arranged to be lower than the outer contour surface of the handle portion 110. Through such an arrangement, it is possible to prevent the user from misoperating or unintentionally operating the surface cleaning device. For example, in the case where the surface cleaning device uses a cleaning liquid with a higher temperature, the relevant operation of the high-temperature cleaning liquid can be ensured. For example, in the case where the high-temperature cleaning liquid is replenished from the base station or cleaned by the high-temperature cleaning liquid, if the relevant control unit is mistakenly triggered, it may cause a safety hazard. In addition, for safety reasons, a control unit in the form of a thumb switch or the like can also be used.

[0035] The connecting rod 120 can be arranged between the handle portion 110 and the main body 200 to connect the handle portion 100 with the main body 200. The connecting rod 120 can be in the form of a hollow tube, for example, it can be a hollow round tube. The connecting rod 120 can be fixedly connected to the handle portion 100 or integrally arranged. The connecting end of the connecting rod 120 is connected to the main body 200.

[0036] Figure 4A schematic diagram showing the handle portion 100 being separated from the main body portion 200 (partially shown) is shown. The connecting end of the connecting rod 120 may be provided with a mounting hole 121 and a mounting groove 122. The mounting groove 122 may be a notch extending along the length direction of the connecting rod 120, or may be a groove provided at the end of the connecting end, and when the connecting rod 120 is inserted into the main body portion 200, the mounting groove 122 may cooperate with a protrusion provided in the main body portion 200, so that the handle portion 100 may be prevented from rotating after the connecting rod 120 is connected to the main body portion 200. In addition, the mounting hole 120 may cooperate with a mounting protrusion 211 provided on the main body portion 100, so that when the connecting rod 120 is connected to the main body portion 200, the mounting protrusion 211 may be embedded in the mounting hole 121 to fix the connecting rod 120. The main body portion 200 may be provided with an inner sleeve 212, wherein the inner sleeve 212 may be inserted into the hollow portion of the connecting rod 120 and tightly matched with the opening of the connecting end of the connecting rod 120. The main body 200 may also be provided with an outer sleeve 213, and the outer sleeve 212 may be tightly sleeved on the outer side of the connecting end of the connecting rod 120. Through the method disclosed in the present invention, the handle part 100 may be detachably mounted to the main body 200. For example, during disassembly, the mounting protrusion 211 may be pressed to disengage it from the mounting hole 121, so that the handle part 100 may be detached from the main body 200. During installation, the connecting rod 120 may be inserted and the lower end of the connecting rod 120 may be allowed to pass through and then be engaged in the mounting hole 121 by the inclined surface setting of the mounting protrusion 211.

[0037] The surface cleaning device may further include a display unit, which may be in the form of an LED or LCD display, a touch screen, or an indicator light. Figure 1 As shown (in Figure 1Only the installation position of the display unit is shown in the figure), the display unit 214 can be arranged on the front side of the main body 200, and the display unit 214 can also be arranged on the upper side of the main body 200. In the present disclosure, it is preferred that the display screen is arranged at the upper position of the front side of the main body 200. In addition, more than two display units may also be included in the present disclosure, for example, they can be arranged at positions such as the front side and the upper side, respectively. The display unit can provide a display interface to display the working posture of the surface cleaning device to the user. In addition, in the case where the display unit is a touch screen, the surface cleaning device can receive the user's instructions through the touch screen. In one embodiment, the display unit can display multiple postures of the surface cleaning device, and can display the posture information of the surface cleaning device, for example, including but not limited to: the condition of the surface to be cleaned (hard floor, carpet, etc.), cleaning mode (such as normal cleaning mode, intensive cleaning mode, boost cleaning mode, etc.), battery power condition, wireless (such as WIFI) connection posture, cleaning liquid level, cleaning liquid storage unit installed in place, recovery storage unit installed in place, recovery liquid level, filter posture, floor type, self-cleaning mode, etc. The gesture display type provided by the display unit may be various display types such as visual display, text display, graphic display or indicator light display.

[0038] According to one embodiment of the present disclosure, the surface cleaning device can communicate wirelessly with a portable device to provide a posture to the portable device and / or receive instructions from the portable device. The portable device can be in various forms such as a smart phone, a tablet computer, a laptop computer, etc. Through a communication connection in the form of a local area network or a wide area network, the interactive interface of the display screen in the portable device can provide the posture of the surface cleaning device to the user, and can also provide relevant instructions to the surface cleaning device through user input. For example, the user can realize any suitable type of control of the surface cleaning device such as self-cleaning, drying, water replenishment, heating, etc. through the interactive interface in the portable device.

[0039] A control circuit unit 700 may be provided in the main body 200 of the surface cleaning device, which may be in the form of a printed circuit board, and an electronic device such as a microcontroller (MCU), a memory, etc. may be provided on the control circuit unit 700, and the control circuit unit 700 may receive instructions from the control unit 111 and / or the display unit 214, may provide various information to the display unit 214, may also receive instructions from a remote portable device, or may provide various information to the portable device, etc. The microcontroller may be operably coupled to various functional systems of the surface cleaning device, such as systems including but not limited to the provision of cleaning liquid and liquid recovery. The user may interact with the microcontroller through the user interface of the control unit 111, the display unit 214, or the portable device, such as the microcontroller may be operably coupled to the control unit 111 to receive instructions input by the user, and may be operably coupled to the display unit 214 to provide various display posture information or receive user instructions. In the present disclosure, the microcontroller may also be configured to execute a cleaning cycle for a self-cleaning operation mode, and the microcontroller may also execute software such as a self-cleaning cycle and a drying cycle.

[0040] The control circuit unit 700 may also be provided with a wireless communication module for wireless communication, and the wireless communication module may be, for example, a WIFI module, through which wireless communication may be performed with a portable device, or may be performed with the control unit 111 (in addition, the control circuit unit 700 may be connected to the control unit 111 by wired communication). When connected to a portable device, the portable device may be downloaded with a corresponding control program or may be a networked device. The wireless communication module may detect whether a wireless network exists, wireless signal strength, router-related information, and may be configured to be connected to the Internet via a local network. In addition, the wireless communication module may be integrated with a microcontroller.

[0041] A power supply unit 800 may be provided in the main body 200 of the surface cleaning device, and the power supply unit may be a battery such as a rechargeable battery, so as to achieve cordless operation. The battery may be a polymer battery or a lithium-ion battery, etc. In one embodiment, the power supply unit 800 may be detachably mounted on the main body 200, and may be charged by removing the power supply unit 800 from the main body 200. In addition, the power supply unit 800 may also be provided with a charging port or a power cord, and the charging port may be used to charge the rechargeable battery without removing the rechargeable battery, or the power cord may be used to achieve corded operation, so that corded operation may be performed when high battery life is required, and in the case of corded operation, the rechargeable battery may be placed in a power-off position (powered by the power cord), and the rechargeable battery may be charged while the surface cleaning device is powered.

[0042] In the present disclosure, the power supply unit 800 is positioned to be isolated from potential liquid contact, for example, to avoid leakage of the cleaning liquid storage unit 300 and / or the recovery storage unit 400, etc. from affecting the power supply unit 800. In the present disclosure, the power supply unit 800 is arranged at a position above the cleaning liquid storage unit 300 and / or the recovery storage unit 400 and is arranged in the main body 200. Preferably, the power supply unit can be arranged at a position below the cleaning liquid storage unit 300 and / or the recovery storage unit 400 and is arranged in the main body 200, and more preferably, it can be arranged in the main body 200 near the connecting part 500. By this arrangement, the center of gravity position of the surface cleaning device can be effectively lowered, thereby reducing the hand pressure of the user. Of course, it should be understood by those skilled in the art that the arrangement of other positions is also possible, and it is only necessary to keep the power supply unit 800 at a distance from the position where liquid leakage may occur.

[0043] In the present disclosure, the various components of the surface cleaning device are relatively arranged so that the surface cleaning device can rotate in two directions. Although it is shown in the present disclosure that it can move in two directions, those skilled in the art can also arrange it to move only in the first direction described below.

[0044] Among them Figures 5 to 7 2 shows the rotation of the surface cleaning device along a first direction (hereinafter also referred to as the X direction), wherein the first direction is in a plane perpendicular to the surface to be cleaned, which can also be referred to as an up and down rotation relative to the surface to be cleaned. Figure 5 A surface cleaning apparatus is shown in an upright position, Figure 6 The surface cleaning device is shown in a 30° rotation position. Figure 7 The surface cleaning device is shown rotated to a parallel posture with the surface to be cleaned. In the first direction, the surface cleaning device (main body) can rotate relative to the surface to be cleaned within a range of 0° to 120°, and can be selected within a range of 0° to 95°, 0° to 110°, etc. The parallel posture with the surface to be cleaned means that the angle between the main body and the surface to be cleaned is 0° or approximately 0° (for example, 0° to 5°, etc.).

[0045] Figures 8 to 10 The surface cleaning device is shown rotating along a second direction (hereinafter also referred to as the Y direction), wherein the second direction is in a plane parallel to the surface to be cleaned, which can also be referred to as left-right rotation relative to the surface to be cleaned. Figure 8 showing a surface cleaning apparatus which is not rotated in a second direction, Fig. 9 showing a surface cleaning device rotating in a second direction, Fig.10 A surface cleaning apparatus is shown which is not rotatable in a second direction.

[0046] like Figure 6 The X-axis about which the X-axis is rotated may be perpendicular to Figure 6 The X-axis about which the Y-axis is rotated can be perpendicular to the X-axis (parallel to the Figure 6 The Y axis may be perpendicular to the axis of the moving wheel of the cleaning base and / or the axis of the roller brush of the cleaning base. When the main body is in an upright position, the Y axis may be at an angle (e.g., an acute angle) to the placement surface of the surface cleaning device, e.g., 80° to 90°, preferably about 80°, such as Figure 5 As shown, the acute angle is the angle between the main body and the cleaning base, that is, the main body moves forward ( Figure 5 When the main body is rotated, the surface cleaning device is in an inclined use position, so that the Y axis will form an acute angle with the placement surface (surface to be cleaned) on the other side (right side), that is, the main body is tilted backward (left). Figure 5 "right" in the middle) is tilted in a downward direction.

[0047] Observe the user's position when using the surface cleaning equipment, such as Figure 5 and Figure 6 As shown, when the surface cleaning device is in an upright posture, the X-axis line is set to be in a position forward of the intersection of the Y-axis line and the surface to be cleaned (to the left in the figure); when the surface cleaning device is in an inclined use posture, the X-axis line is set to be in a position backward of the intersection of the Y-axis line and the surface to be cleaned (to the right in the figure).

[0048] The rotation of the surface cleaning device can be defined by the above-described connection portion 500 , which can be a separate component fixed to the lower end of the main body 200 , or the connection portion 500 can be a component integrally formed with the main body 200 and located at the lower end of the main body 200 .

[0049] The connecting part 500 is used to connect the main body 200 with the cleaning base 600. The connecting part 500 may be a hollow structure, and the air, fluid communication and power supply required for the main body 200 and the cleaning base 600 such as a floor brush may be realized through the connecting part 500, so that power supply, air and / or liquid circulation may be realized between the main body 200 and the cleaning base 600 via the wiring and / or pipeline passing through the connecting part 500. In addition, a flexible hose for vacuuming and recovering liquid may pass through the connecting part.

[0050] like Fig.11As shown, a recovery hose for recycling liquid and garbage etc. can be accommodated inside the connecting portion 500, and the outlet 506 of the hose can be communicated with the recycling storage portion. The recovery hose is a flexible material and can be deformed according to the inclination of the surface cleaning device. In addition, a cleaning liquid supply pipeline 308 can be accommodated, and the cleaning liquid supply pipeline 308 can pass through the connecting portion 500 and be communicated with the corresponding pipeline in the cleaning base 600, so that the cleaning liquid is sent to the cleaning base 600. The cleaning liquid supply pipeline 308 can be rigid and will not bend with the rotation of the connecting portion. In addition, a liquid detection device can also be provided at the cleaning liquid supply pipeline 308 to detect whether the cleaning liquid is provided to the cleaning base 600, and the detection signal of the liquid detection device can be provided to the microprocessor etc.

[0051] According to one embodiment, the connection portion 500 may include a universal joint so that the main body 200 can rotate relative to the cleaning base 600 in two directions.

[0052] According to one embodiment, the connection portion 500 may include a multi-axis joint, which may couple the main body 200 with the cleaning base 600 so as to allow the main body 200 to rotate relative to the cleaning base 600 along a first direction and a second direction.

[0053] like Figure 5 As shown, the main body 200 can be pivoted to an upright position (also known as a storage position) through the connecting portion 500, in which the angle between the main body 200 and the surface of the cleaning base 600 (or the ground on which it is placed) is 80° to 90°, preferably about 80°. In this position, the surface cleaning device is in a self-supporting posture (also known as an upright posture), that is, the main body 200 can be supported by the cleaning base 600, and the upright posture can be achieved without the help of other objects.

[0054] When the rotation in the X direction is limited by a pivot joint, for example Figure 5 As shown, the surface of the cleaning base 600 may be provided with a supporting protrusion 501, and correspondingly, the connecting portion 500 may be provided with a supporting engaging portion 502 (eg, Figure 6 As shown in Figure 8As shown, the support protrusion 501 may be formed with a support groove 503, and the support groove 503 is correspondingly arranged with the support fitting 502, so that when the main body 200 is in an upright position (for example, between 80° and 90° relative to the forward direction), the support fitting 502 is fitted into the support groove 503, and since the cleaning base 600 is placed on the ground, it can form a base, and due to the abutment between the support fitting 502 and the support protrusion 501, the surface cleaning device is in a self-supporting posture. The support fitting 502 and the support protrusion 501 also have a releasable locking effect, and when the main body is in an upright position, the two are engaged. When pivoting from the upright position to the main body, the user can apply a certain force to disengage the two.

[0055] When the main body 200 is rotated along the X direction, the supporting engaging portion 502 and the supporting protruding portion 501 can be separated, for example Figure 6 After the supporting engaging portion 502 and the supporting protruding portion 501 can be separated, and until the main body 200 can rotate to a predetermined angle, the main body 200 can rotate along the Y direction. Figure 8 FIG. 2 shows that the main body 200 is rotated to an angle. Fig. 9 It is shown that the main body 200 rotates along the Y direction at this angle. Here, the predetermined angle can be an angle of 30° with the horizontal direction of the surface to be cleaned. Of course, it can also be set to other angles, such as about 20°.

[0056] like Figure 7 As shown, the main body 200 can eventually rotate along the X direction to a position horizontal to the surface to be cleaned, and when the angle is less than the above predetermined angle (for example, less than 30°), the main body 200 can be prevented from rotating along the Y direction relative to the cleaning base 600.

[0057] The connection portion 500 may be provided with a limiting protrusion 504. The limiting protrusion 504 may be provided on a side of the connection portion 500 on the opposite side of the supporting interlocking portion 502, and it may be integrally formed with the connection portion 500. The limiting protrusion 504 protrudes relative to the surface of the connection portion 500, and the limiting protrusion 504 may include at least a limiting plane 505. The limiting plane 505 may be provided at positions on both sides of the connection portion 500. Accordingly, the cleaning base 600 may include an outwardly extending mounting member 6611. In the present disclosure, the number of mounting members 6611 is two, and they extend outwardly from the cleaning base 600 respectively. The mounting member 6611 may be used to support two moving wheels. For example, the roller of the moving wheel may be fixed to the extension arm. The two mounting members 6611 are spaced apart by a predetermined distance, wherein the distance may be equal to or slightly greater than the distance between the two limiting planes 505, so that when the main body 200 is within a predetermined angle range (e.g., 0° to 30°) after rotation, the two limiting planes 505 may contact the inner wall surfaces of the two mounting members 6611 respectively, thereby limiting the main body from rotating along the Y direction. It should be noted that when not within the predetermined angle range, the mounting member 6611 should not impose any restriction on the rotation of the main body 200.

[0058] Furthermore, at least one of the two extension arms may be configured as a hollow structure, through which wires and / or pipelines may be allowed to pass, so as to connect the main body portion with the cleaning base.

[0059] According to the technical solution of the present disclosure, when the user operates the surface cleaning device in a spacious space, since the angle between the main body 200 and the surface to be cleaned will not be too small (for example, the case of more than 30°), since the mounting member 6611 will not have any effect on the rotation in the Y direction, the user can rotate the main body 200 along the Y direction, thereby guiding the cleaning base 600 to turn left and right (Y direction). However, when the user needs to operate the surface cleaning device in a narrow or low space (such as the bottom of the sofa, etc.), if the posture of the main body 200 is not lowered, the surface cleaning device will not be able to enter the narrow or low space, so that this space will not be cleaned. In the present disclosure, the user can adjust the main body 200 to make its posture lower, so that the main body 200 can extend into the narrow or low space. When the posture of the main body 200 is lower than the predetermined angle, the user's control ability of the surface cleaning device begins to decline, and it is not expected that the main body 200 rotates in the Y direction relative to the cleaning base 600. In this way, the two limiting planes 505 can be in contact with the inner wall surfaces of the two mounting parts 6611 respectively to limit the rotation in the Y direction, so that the user cannot guide it left or right.

[0060] In addition, although not shown in the figure, a pivoting portion (e.g., a circular pivoting shaft) may be provided on the inner wall surface of the mounting member 6611, and the pivoting portion is rotatably connected to the connecting portion (e.g., connected to the wall surface of the connecting portion, or a corresponding lug is provided on the connecting portion and the lug is connected to the pivoting portion). In addition, pivoting portions may be provided on the inner wall surfaces of the mounting members 6611 on opposite sides so as to be connected to the connecting portion. Through the pivoting portion, the surface cleaning device can be rotated along the X direction.

[0061] Furthermore, in the present disclosure, when the surface cleaning device is in an inclined use position (for example, when the angle with the surface to be cleaned is greater than or equal to 30°), the rotation angle in the Y direction can be limited to prevent the rotation angle in the Y direction from being too large.

[0062] In addition, the connecting part 500 can be detachably mounted on the cleaning base 600. For example, a buckle structure can be provided between the two, for example, a mounting hole is provided on the connecting part, and a buckle protrusion is provided on the cleaning base, and the two are combined by fitting the buckle protrusion into the mounting hole, and the two are separated by pressing the buckle protrusion to leave the mounting hole.

[0063] In this disclosure, Figure 7 As shown, when the main body 200 is in a "lying flat" (parallel to the surface to be cleaned) posture, the height of the main body 200 is set to be less than or equal to 120 mm, for example, the height can be set to 100 mm to 120 mm, or 105 mm to 120 mm, etc. In addition, the height of the cleaning base 600 is set to be less than or equal to the height of the main body 200. In addition, the width of the cleaning base 600 should be set to be greater than or equal to the width of the main body 200 (the "width" mentioned here refers to the width of the cleaning base and the main body in the direction perpendicular to the direction of travel of the surface cleaning device (the two directions are in the horizontal plane)).

[0064] In addition, in order to facilitate the user to move the surface cleaning device when the main body 200 is in a "lying flat" position (parallel to the surface to be cleaned), parallel rollers 215 may also be provided. Figure 7 In the lying-flat posture shown, according to the parallel rollers 215, the user can operate the surface cleaning device by holding the handle portion without providing support force for the surface cleaning device. The support force of the surface cleaning device can be achieved by the moving wheels and the parallel rollers. In this way, in the lying-flat posture, the user only needs to apply a dragging force to operate the surface cleaning device. In addition, the setting position of the parallel rollers 215 is separated from the center of gravity position of the surface cleaning device or the center of gravity position of the main body to prevent the surface cleaning device from tilting and the like. The parallel rollers can be arranged on the main body, or on the handle portion, etc.

[0065] According to the above embodiments of the present disclosure, the user can make the main body rotate in both the X direction and the Y direction within a certain angle range, and can easily guide the cleaning base, while within another angle range, the main body will be restricted from rotating in the Y direction. This arrangement allows the user to better operate the surface cleaning device.

[0066] like Figure 3 As shown, the main body 200 may include a frame body 220 to support the cleaning liquid storage part 300 and the recovery storage part 400, and may also be used to support other components, such as motors, fans and other components. For example, two accommodating walls may be provided on the portion of the frame body 220 that accommodates the cleaning liquid storage part 300 and the recovery storage part 400, and the liquid storage part 300 and the recovery storage part 400 are at least partially accommodated in the two accommodating walls, and the accommodating walls may constitute the housing of the surface cleaning device. In the case of two accommodating walls, the accommodating walls are provided on opposite sides of the side of the surface cleaning device that is different from the cleaning liquid storage part 300 and the recovery storage part 400, and extend in the height direction of the surface cleaning device.

[0067] The cleaning liquid storage part 300 and the recovery storage part 400 can be arranged on the frame body 220, so as to be located on both sides of the main body 200. In the present disclosure, the cleaning liquid storage part 300 and the recovery storage part 400 are optionally located on the left and right sides of the main body 200 (relative to the direction of travel and the cleaning path of the surface cleaning device). The thickness of the cleaning liquid storage part 300 can be less than or equal to the thickness of the recovery storage part 400, and the heights of the two can be the same or substantially the same. It should be noted that although the present disclosure is mainly based on the example that the cleaning liquid storage part 300 and the recovery storage part 400 are located on the left and right sides of the main body 200, it is also preferred in the present disclosure that the cleaning liquid storage part 300 and the recovery storage part 400 are arranged on the front and rear sides of the main body 200 (the front and rear sides along the cleaning direction). In the case of being arranged on the front and rear sides, the corresponding arrangement relationship of the various components described herein is also the same or similar.

[0068] In the present disclosure, the cleaning liquid storage section 300 and the recovery storage section 400 can be detachably mounted to the side of the frame body 220, and the sides to which the two are mounted can be opposite sides of the frame body 220. The thickness of the cleaning liquid storage section 300 and the recovery storage section 400 is set to be smaller than the width, so as to ensure sufficient capacity and enable the height of the main body 200 to be less than a predetermined height, for example 120 mm, when lying flat.

[0069] exist Fig.12 and Fig.13 A schematic diagram of a cleaning liquid storage part 300 according to an embodiment of the present disclosure is shown. Fig.14The schematic diagram of the cleaning liquid storage part 300 after a part of the wall is removed is shown. The cleaning liquid storage part 300 is used to store the cleaning liquid and provide it to the cleaning base 600 via a pipeline. In this article, the cleaning liquid can be one or more of any suitable liquids, including but not limited to cleaning water, concentrated detergent, diluted detergent, or a mixture thereof. In addition, the cleaning liquid can be a normal temperature cleaning liquid or a high temperature cleaning liquid.

[0070] like Figure 12 to Figure 14 As shown, the shape of the cleaning liquid storage part 300 is a flat shape, and includes a cavity formed by a plurality of wall surfaces to accommodate the cleaning liquid, and the capacity of the cleaning liquid storage part 300 can be set to 500mL, etc. The cleaning liquid storage part 300 may include a handle 301 and a pressing part 302, preferably the handle 301 and the pressing part 302 are located at the upper side of the cleaning liquid storage part 300. The user can install or remove the cleaning liquid storage part 300 through the handle 301. Specifically, the user can disengage the latch 303 from the groove provided in the main body by pinching the pressing part 302 (with a spring built in) to move it downward, so that the cleaning liquid storage part 300 can be removed. In the present disclosure, although the handle 301 is shown as an embedded handle (hidden handle), those skilled in the art can also set it as a handle protruding outward. As shown in the figure, the surface of the upper wall of the cleaning liquid storage part 300 is set as an inclined surface, so that when the cleaning liquid storage part 300 is installed, the cleaning liquid storage part 300 can be pushed onto the main body 200 and fixed to the main body 200 by the action of the latch 303.

[0071] The cleaning liquid storage part 300 may be provided with a liquid inlet 305, and the liquid inlet 305 may be closed by a cover plate 304. Thus, when providing cleaning liquid to the cleaning liquid storage part 300, the cover plate 304 may be opened to input the cleaning liquid through the liquid inlet 305. The cover plate 304 may then be closed to block the liquid inlet 305, thereby preventing leakage of the cleaning liquid when the surface cleaning device is used. The cover plate 304 may be pivoted relative to the wall surface of the cleaning liquid storage part 300, for example, the underside of the cover plate 304 may have a pivot axis and the pivot axis may be inserted into the wall surface.

[0072] In addition, the cover plate 304 and the liquid inlet 305 are provided with a blocking part such as a plunger correspondingly, so that the liquid inlet 305 is blocked by the blocking part when changing the closure, and at this time, the blocking part at least partially enters the liquid inlet 305. Of course, those skilled in the art should understand that other sealing forms can also be used.

[0073] A vent valve may be provided at or near the liquid inlet 305, and the vent valve may be a two-way vent valve, which is used to selectively inhale gas into the clean liquid storage part 300 or discharge gas from the clean liquid storage part 300, so as to balance the internal and external pressures of the clean liquid storage part 300. In addition, the vent valve may be provided on the upper wall of the clean liquid storage part 300, and may be spaced a predetermined distance from the liquid inlet 305. When the cover plate 304 is closed, the liquid inlet 305 and the vent valve may be covered. When the gas pressure on both sides of the two-way vent valve is unbalanced, the vent valve may be deformed instantly, so that the internal and external gas flow to achieve internal and external pressure balance.

[0074] According to one embodiment of the present disclosure, the cleaning liquid storage unit 300 may also include a filter 306, which is arranged at the liquid outlet of the cleaning liquid storage unit 300, and the cleaning liquid provided to the outside by the cleaning liquid storage unit 300 is filtered by the filter 306 to filter out impurities in the cleaning liquid. An outlet valve 307 may also be provided to be connected to the liquid outlet so as to selectively allow the cleaning liquid to flow out from the liquid outlet. When the cleaning liquid storage unit 300 is installed on the main body 200, the outlet valve 307 may be opened to allow the cleaning liquid to be provided, and when the cleaning liquid storage unit 300 is removed from the main body 200, the outlet valve 307 may be closed to prevent the cleaning liquid from leaking. The filter 306 may be installed on one side of the lower wall of the cleaning liquid storage unit 300 and the outlet valve 307 may be installed on the other side, and the position where the two are installed is the position of the liquid outlet.

[0075] The outlet valve 307 can be communicated with the cleaning liquid supply pipeline 308, which can be accommodated inside the connecting portion 500 as described above and communicated with the supply pipeline of the cleaning base 600. In addition, a liquid detection device can be provided near the cleaning liquid supply pipeline 308 or the outlet valve 307 to detect whether cleaning liquid is provided to the cleaning base 600. The liquid detection device can be any suitable detection device for detecting whether cleaning liquid is present in the cleaning liquid supply pipeline 308. The liquid detection device can be a conductivity sensor and is located in the cleaning liquid supply pipeline 308 to detect whether cleaning liquid is present.

[0076] When the liquid detection device detects that there is no liquid, it indicates that there is no cleaning liquid in the cleaning liquid storage part 300 or the cleaning liquid storage part 300 has been removed. The liquid detection device can provide a signal to the microcontroller, and the microcontroller can provide information to the user through the display part. In addition, the liquid detection device can also be located inside the cleaning liquid storage part 300 to detect the liquid level of the cleaning liquid storage part 300. In this way, when the liquid level is too low, indicating that there is no cleaning liquid in the cleaning liquid storage part 300, a signal can be provided to the microcontroller, or when the cleaning liquid storage part 300 is removed from the main body 200, the electrical connection of the liquid detection device is disconnected, and the microcontroller can also know that the cleaning liquid storage part 300 has been removed.

[0077] The input from the liquid detection device can be further used by the microcontroller to determine the appropriate shutdown or otherwise interruption of the supply system of the cleaning liquid. For example, when there is no cleaning liquid in the cleaning liquid storage unit 300 or it is removed, the microcontroller can shut down at least one electrical component of the surface cleaning device or prevent at least one electrical component from being activated. The electrical component can include a pump, a valve, various motors, etc., so that the operation of the surface cleaning device can be stopped.

[0078] When the surface cleaning device is in a lying position, the height of the cleaning liquid storage part 300 can be set to be significantly greater than its width, and the liquid outlet of the cleaning liquid storage part 300 can be set at a lower position of the lower wall surface of the cleaning liquid storage part 300 ( Fig.14 to the right of ).

[0079] Figures 15 to 18 FIG. 4 is a schematic diagram of a recycling storage unit 400 according to an embodiment of the present disclosure. Fig.15 A schematic diagram showing an angled view of the recycling storage unit 400 is shown. Fig.16 A schematic diagram of the recycling storage unit 400 from another angle is shown. Fig.17 An exploded view of a portion of the recycling storage unit 400 is shown, Fig.18 An exploded view of the recycling storage section 400 is shown.

[0080] like Figures 15 to 18As shown, the recovery storage unit 400 includes a cavity formed by a plurality of wall surfaces to accommodate the recovery liquid. The recovery storage unit 400 may include a second handle 401 and a second pressing portion 402, preferably the second handle 401 and the second pressing portion 402 are located at the upper side position of the recovery storage unit 400. The user can install or remove the recovery storage unit 400 through the second handle 401, specifically, the user can disengage the second latch 403 from the groove provided in the main body by pinching the second pressing portion 402 (with a spring built in) to move it downward, so that the recovery storage unit 400 can be taken out. In the present disclosure, although the second handle 301 is shown as a handle protruding outward, it can also be set as an embedded handle (hidden handle) by a person skilled in the art. As shown in the figure, the surface of the upper wall of the recovery storage unit 400 is set as an inclined surface, so that when the recovery storage unit 400 is installed, the recovery storage unit 400 can be pushed onto the main body 200 and fixed to the main body 200 by the action of the second latch 403.

[0081] An inlet 404 may be provided at the lower side of the recycling storage part 400 , and the inlet 404 may be communicated with the outlet 506 of the hose, so that the recycled solid waste or recycled liquid can enter the recycling storage part 400 through the inlet 404 .

[0082] In addition, a liquid level detection unit 405 may be provided in the recovery storage unit 400, wherein a plurality of liquid level detection units 405 may be provided so that the liquid level of the internal recovery liquid when the recovery storage unit 400 is in an upright position can be detected, and the liquid level of the internal recovery liquid when the recovery storage unit 400 is in a horizontal position can be detected, which will be described in detail later.

[0083] According to one embodiment of the present disclosure, the recycling storage part 400 may include two parts: a first storage part 406 and a second storage part 407. The first storage part 406 and the second storage part 407 are separable. When it is necessary to remove garbage and recycled liquid from the recycling storage part 400, the first storage part 406 and the second storage part 407 may be separated. When the first storage part 406 and the second storage part 407 are combined together, a seal may be provided between the two to ensure that the recycled liquid does not leak.

[0084] like Fig.17 and Fig.18As shown, the top wall of the first storage unit 406 may be provided with an exhaust port 408, which provides a passageway for the gas in the suction process of the surface cleaning device to be discharged from the surface cleaning device. A gas filter assembly may also be provided on the outside of the exhaust port 408, and the gas filter assembly may be, for example, a filter of any suitable form such as a HEPA filter. The gas filter assembly may be provided in the first storage unit 406, or may be provided in the main body 200 above the first storage unit 406. For example, when the gas filter assembly is provided in the main body 200, the gas filter assembly may be provided near the exhaust port 408 to receive the gas from the exhaust port 408. For example, a filter assembly receiving portion may be provided at a corresponding position of the main body 200, and the gas filter assembly may be detachably mounted in the filter assembly receiving portion.

[0085] The gas filter assembly may include a filter medium supported on a support, and in one embodiment, the filter medium may be a pleated filter medium and may be made of a material that remains porous when wet. The gas filter assembly may also include a mesh screen carried by the support and disposed on the gas upstream side of the filter medium for filtering large particles of matter. The gas filter assembly may be designed as an integral assembly so as to be removed from the filter assembly receiving portion for replacement, etc.

[0086] The first storage part 406 may contain a gas-liquid separation device 420, wherein the gas-liquid separation device 420 may include a gas-liquid separation motor 421 and a gas-liquid separator 422. The rotation of the gas-liquid separation motor 421 drives the gas-liquid separator 422 to work, so that the recovered gas and liquid are separated from each other, so that the liquid remains in the recovery storage part 400, and the gas is discharged from the surface cleaning device after being filtered.

[0087] In one embodiment of the present disclosure, the rotating shaft of the gas-liquid separation motor 421 can be coupled to the first synchronous pulley 423, and the second synchronous pulley 424 is coupled to the first synchronous pulley 423 through a synchronous belt 425, so that when the gas-liquid separation motor 421 rotates, the second synchronous pulley 424 rotates accordingly. The second synchronous pulley 424 and the bearing 426 are coupled to the drive shaft 427, and the drive shaft 427 is used to drive the gas-liquid separator 422 to rotate.

[0088] In one embodiment, the recycling storage unit 400 may further include a filter 430. Figures 19 to 21 The filter 430 will be described in detail. Fig. 20 and Fig.21 4 shows the relative arrangement of the filter 430 and the gas-liquid separation device 420. The filter 430 may include a solid storage portion 431, a conduit passage port 432, a filter portion 433, a second surge prevention portion 434, and a first surge prevention portion 435.

[0089] The solid storage part 431 can be used to store solid waste recovered during the cleaning process, such as debris, hair, etc. The solid storage part 431 includes at least a bottom wall 4311, a first side wall 4312 and a top wall 4313, wherein a liquid guide hole is provided on the bottom wall 4311 and the first side wall 4312, so that the recovered liquid flows out from the solid storage part 431 to the cavity of the recovery storage part 400, leaving only solid waste. Wherein, the size of the liquid guide hole is designed to allow only liquid or liquid and fine debris to pass through. The solid storage part 431 may also include an open part, so that when the user cleans the solid waste, the solid waste can be poured out through the open part. A conduit through port 432 may be provided on the bottom wall 4311, and the conduit through port 432 allows a recovery conduit (not shown in the figure) to pass through, wherein the recovery conduit is connected to the inlet 404 of the liquid storage part 400, so that when the surface cleaning device is working, the recovered liquid or solid, etc., are guided to the filter 430.

[0090] In addition, the solid storage portion 431 may further include a second side wall 4314 and a third side wall 4315, wherein the second side wall 4314 and the third side wall 4315 are arranged opposite to each other and extend between the bottom wall 4311 and the top wall 4313. In the present disclosure, the second side wall 4314 and the third side wall 4315 are arranged only at a portion between the bottom wall 4311 and the top wall 4313, and the unarranged position may serve as the above-mentioned open portion. The solid storage portion 431 may further include a fourth side wall 4316, which extends upward from the bottom wall 4311, but does not extend to the top wall 4313, and is only arranged to extend a certain distance, so that a space for accommodating solids can be formed by the fourth side wall 4316, the second side wall 4314, the third side wall 4315 and the bottom wall 4311, and garbage can also be easily cleaned through the open portion. End surfaces of the fourth side wall 4316 , the second side wall 4314 , the third side wall 4315 and the top wall 4313 may be configured to fit the inner wall of the recovery storage portion 400 .

[0091] A space is provided on the top wall 4313 and a filter screen (not shown) is detachably installed to form a filter section 433, wherein the shape of the space may be similar to an L-shape and is provided on the top wall 4313 near the first side wall 4312. In addition, a conduit support portion 436 may be provided on the top wall 4313, and the conduit support portion 436 extends toward the interior of the solid storage portion 431 by a predetermined length so as to support the end (open end) of the recovery conduit. In addition, after supporting the end of the recovery conduit, the open end of the recovery conduit may face the top wall 4313 and be spaced a certain distance from the top wall 4313. Fig. 20As shown, since the top wall 4313 is disposed between the open end of the recovery conduit and the gas-liquid separator 422 and separates the two, the recovery liquid from the open end of the recovery conduit can be prevented from reaching the gas-liquid separator 422 by the blocking effect of the top wall 4313. When the recovery liquid mixed with solids enters the space formed by the solid storage part 431 through the recovery conduit, the solids are retained in the space of the solid storage part 431 through the filter part 433 in the form of a filter net, etc., and only the liquid is allowed to enter the space where the gas-liquid separator 422 is located through the filter part 433, so that the solids remain in the solid storage part 431.

[0092] The second anti-surge portion 434 is configured in the form of a partition, and one or more liquid through holes are opened on the partition to allow the recovered liquid to pass through. When the recovered liquid passes through, the barrier effect of the partition prevents the rapidly changing liquid from forming waves in the recovery storage portion 400, and the liquid through holes allow the liquid in the space on both sides of the second anti-surge portion 434 to be connected.

[0093] For example, when the surface cleaning device is changed from an upright posture to an inclined use posture, or a parallel posture (lying flat posture), or from an inclined use posture to a parallel posture, the angle of the surface cleaning device changes, and the recovered liquid stored in the recovery storage unit 400 will generate waves. If the waves are not suppressed, the liquid may enter the gas-liquid separator 422. Therefore, the waves can be blocked by the partition of the second anti-surge unit 434, and the liquid can also flow through the liquid through hole provided on the partition. In addition, at least one (for example, three) end faces of the second anti-surge unit 434 can fit the interior of the recovery storage unit 400.

[0094] In addition, the opening area occupied by the filter part 433 can be set to be greater than or equal to the opening area occupied by one or more liquid through holes provided in the second anti-surge part 434 (for example, the total opening area occupied by the two filter parts 433 can be set to be greater than or equal to the total opening area occupied by the liquid through holes), so that at least when the surface cleaning device is in a parallel posture, air mainly enters the gas-liquid separator 422 from the position of the filter part 434. In this way, when observed in a parallel posture, it is prevented from the liquid from reaching the gas-liquid separator 422 through the first anti-surge part 435 from the lower part of the first anti-surge part 435, affecting the gas-liquid separation effect of the gas-liquid separator 422.

[0095] The first anti-surge portion 435 is disposed opposite to the gas-liquid separator 422, and optionally, the central axis of the first anti-surge portion 435 is parallel to or coincides with the central axis of the gas-liquid separator 422. In the present disclosure, the two central axes preferably coincide with each other (e.g., Fig. 20The central axis of the gas-liquid separator 422 may be the axis at which the center of its driving shaft is located, and the central axis of the first anti-surge portion 435 may be the central axis of the hollow portion of the first anti-surge portion 435 mentioned below.

[0096] As shown in the figure, the first surge prevention part 435 may include an edge portion 4351, a transition portion 4352 and a hollow portion 4353. The transition portion 4352 is located between the edge portion 4351 and the hollow portion 4353. From the plane where the edge portion 4351 is located, the transition portion 4352 extends obliquely to the hollow portion 4353, so that the transition portion forms an inclined surface between the edge portion 4351 and the hollow portion 4353. When the surface cleaning device with the recovery storage part 400 installed is observed in a parallel posture, the inclination direction of the transition portion 4352 is a downward direction, and the inclination direction of the transition portion 4352 is a direction away from the gas-liquid separator 422.

[0097] In this way, the liquid in the space where the gas-liquid separator 422 is located can enter the first anti-surge portion 435 and slide down along the transition portion 4352. In addition, due to the shape of the first anti-surge portion 435, when the surface cleaning device is changed from an upright posture to an inclined use posture, or a parallel posture (lying posture), or from an inclined use posture to a parallel posture, due to the angle change of the surface cleaning device, the first anti-surge portion 435 can also offset the waves generated by the angle change, thereby preventing the liquid from entering the gas-liquid separator 422 due to the waves.

[0098] In addition, when the surface cleaning device (correspondingly the recovery storage unit 400) changes its posture between the inclined use posture and the parallel posture, waves may also be formed between the first cavity and the fourth cavity, and the waves may affect the open end of the recovery duct 440, and may even affect the gas-liquid separator 422. In order to avoid these effects, the bottom wall 4311 can be used as a third anti-surge portion, wherein when the wave contacts the bottom wall 4311, the wave can be offset by the avoidance of the bottom wall 4311, and the fluid communication between the first cavity and the fourth cavity is achieved through the liquid guide hole of the bottom wall 4311. In addition, in an optional embodiment, the first side wall 4312 can also be used as the third anti-surge portion, and the principle of its implementation is the same as that of the bottom wall 4311, which will not be repeated.

[0099] Therefore, according to the above-mentioned method of the present disclosure, a three-level surge protection function can be achieved, thereby preventing a large amount of liquid from entering the gas-liquid separator 422.

[0100] As described above, when the user needs to clean the garbage in the filter 430, the filter 430 can be taken out from the recycling storage section 400, so that the first anti-surge section 435 can be used as a hand-held portion for the user to extract the filter 430. When the first storage section 406 and the second storage section 407 are separated, the user can access the filter 430 contained therein through the opening of the second storage section 407, and then take out the filter 430 by holding the first anti-surge section 435. In an optional embodiment, when the filter 430 is installed in the second storage section 407, the first anti-surge section 435 protrudes outward relative to the second storage section 407 for the user to hold.

[0101] In the present disclosure, the filter 430 may be integrally formed or fixedly arranged, and as shown in FIG. Fig. 20 As shown, the extension axis of the top wall 4313 and the second anti-surge portion 434 coincide, or may be a plate-like portion, and the solid storage portion 431 is located on one side of the plate-like portion, while the first anti-surge portion 435 is located on the other side of the plate-like portion. The first anti-surge portion 435 may be fixed to the top wall 4313 or integrally formed with the top wall 4313, etc., and relative to the central axis of the solid storage portion 431 (the central axis extending in the height direction of the recovery storage portion 400 in an upright posture), the extension direction of the first anti-surge portion 435 deviates from the central axis so as to lift the filter 430 and provide a larger installation space for the filter portion 433.

[0102] The inner cavity of the recovery storage unit 400 can be divided into a first cavity, a second cavity and a third cavity according to the space formed by the filter 430 and the shell of the recovery storage unit 400. The first cavity is the space formed by the second anti-surge unit 434 and the first side wall 4312; the second cavity is the space formed by the first anti-surge unit 435 and the second anti-surge unit 434; the third cavity is the space formed by the first anti-surge unit 435 and the top wall 4313, that is, the space where the gas-liquid separator 422 is located; the fourth cavity is the space where the solid storage unit 431 is located.

[0103] When the liquid flows from the first cavity to the second cavity, the second anti-surge portion 434 prevents the formation of waves in the second cavity. When the liquid flows from the second cavity to the third cavity, the first anti-surge portion 435 prevents the formation of waves in the third cavity.

[0104] Fig. 22 An oblique cross-sectional view of the recovery storage unit 400 is shown. Fig.23 A partial cross-sectional view of the recovery storage section 400 is shown.

[0105] like Fig. 22 and Fig.23It is a schematic diagram showing the recovery storage unit 400 in a parallel posture. It should be noted that although the parallel posture is used as an example for explanation, the principle is the same in the case of the inclined use posture and the upright posture, and will not be repeated.

[0106] In the present disclosure, a suction source 460 (such as Figure 3 As shown), in order to suck the recovered liquid, gas and / or solid, wherein the suction source can be arranged at a downstream position of the gas-liquid separator 422. The suction source can be arranged in a housing, and the housing can include a suction motor housing and a fan housing, the suction motor housing can accommodate the suction motor, and the fan housing can accommodate the fan. The other two can also be arranged in a housing. The fan housing can include a gas inlet to suck the gas into the fan housing, and the gas inlet can be roughly aligned with the central area of ​​the fan, for example, the central area can be the central axis of the motor. The fan housing can also include a gas outlet, through which the gas is discharged. The suction motor can be a brushless DC motor, which can be directly powered by a rechargeable battery. In the case of wired power supply, an AC-DC conversion component can be provided in the control circuit part to convert AC power into DC power and provide it to the motor to achieve long-lasting cleaning.

[0107] The suction source 460 is arranged at a position independent of the recovery storage unit 400, for example, it can be arranged in the upper shell 210 of the main body 200. The upper shell 210 and the frame body 220 can be detachably installed or integrally formed. The upper shell can also accommodate a power supply unit 800 such as a rechargeable battery and a control circuit unit 700. In addition, a sound device 900 is arranged on the side of the upper shell 210, and the sound device 900 can be connected to the control circuit unit 700 so that a sound is emitted through the sound device 900 to prompt the user, etc.

[0108] The recovered liquid, gas and / or solid are sucked through the recovery conduit 440 and enter the fourth cavity, where the solid (for example, solid waste other than debris) will remain in the solid storage part 431. Part or all of the liquid can flow into the first cavity through the liquid guide hole in the bottom wall 4311 and / or the first side wall 4312, and the gas, liquid and / or water vapor (there may also be debris filtered by the filter part) will enter the third cavity through the filter part 433, wherein the function of the filter part 433 here is to block the solid and allow the liquid and gas (which may be mixed with some debris) to pass. In the third cavity, the gas and liquid are separated by the gas-liquid separator 422 so that the gas passes and is discharged along the channel, so that the liquid (which may have debris) remains in the third cavity (the liquid and / or small particles of garbage are thrown away in the third cavity by the rotation of the gas-liquid separator 422). When the recovery storage part 400 is in a parallel posture or an inclined use posture, the liquid in the third cavity can enter the second cavity through the hollow portion of the first anti-surge part 435. The first cavity and the second cavity can be fluidically connected through the liquid through hole of the second anti-surge part 434, wherein when the recovery storage part 400 is in an upright posture or an inclined use posture, the liquid in the third cavity can flow into the fourth cavity through the filter part 433, and then flow from the fourth cavity into the first cavity.

[0109] Fig. 22 The arrows in the figure show the flow path of the gas, wherein the gas enters the recovery conduit 440 from the inlet port 404, flows into the first chamber along the recovery conduit 440, then flows into the second chamber through the filter portion 433, the gas is separated by the gas-liquid separator 422, and then discharged from the exhaust port 408 through the gas channel.

[0110] The recovery conduit 440 (or its central axis) is arranged to be offset from the longitudinal central axis of the recovery storage part 400, and can be parallel to the longitudinal central axis. It is arranged so that when it is installed to the recovery storage part 400, the recovery conduit 440 is closer to the main body or closer to the cleaning liquid storage part 300 than the longitudinal central axis. In the present disclosure, when the recovery storage part 400 is in a parallel posture, the position of the recovery conduit 440 can be set to be close to the upper side of the recovery storage part 400. From another perspective, when the recovery storage part 400 is in an upright posture or an inclined use posture, the position of the recovery conduit 440 can be set to be close to the front side of the recovery storage part 400. In addition, in an optional embodiment of the present disclosure, the recovery conduit 440 can be fixed on the wall of the recovery storage part 400 or integrally formed with the wall. In this way, when the surface cleaning device is in a parallel posture (lying flat), the liquid in the recovery storage part 400 can be prevented from entering the recovery conduit 440. When the surface cleaning device is in an upright posture or an inclined use posture, the liquid level of the liquid in the recovery storage portion 400 may also be made lower than the open end of the recovery conduit 440 to prevent the recovered liquid from entering the recovery conduit 440 .

[0111] like Fig.23 As shown in the enlarged portion of part A of the recovery storage unit 400, in order to prevent liquid or water vapor from leaking from the third cavity into the gas channel and thus deteriorating the gas-liquid separation effect, a labyrinth seal structure may be provided at the connection portion between the third cavity and the gas channel, wherein the labyrinth seal structure may include a first baffle 451, a second baffle 452, and a third baffle 453, wherein in the direction from the third cavity to the gas channel, the first baffle 451 may be provided at an upstream position, the second baffle 452 may be provided at a midstream position, and the third baffle 453 may be provided at a downstream position. The first baffle 451 and the third baffle 453 may be provided on the bracket (or the wall thereof) of the recovery storage unit 400, and the second baffle 452 may be provided on the gas-liquid separator 422 (e.g., the housing of the gas-liquid separator 422). When the recovery storage unit 400 is in a parallel posture, the first baffle 451 and the third baffle 453 extend downward, while the second baffle 452 extends upward. In this way, the first baffle 451, the second baffle 452, the third baffle 453, the bracket (or wall) of the recovery storage unit 400, and the shell of the gas-liquid separator 422 can form a three-level labyrinth seal structure, thereby preventing liquid or water vapor from entering the gas channel. In one embodiment of the present disclosure, the liquid level detection unit 405 can be used to detect the liquid level of one or more postures of the liquid in the recovery storage unit 400, for example, the liquid of the recovery liquid in at least one of the parallel posture, the self-supporting state, and the parallel posture and the self-supporting state can be detected.

[0112] The first limit liquid level threshold of the liquid level detection device is set as: when the recovery storage part is in a parallel posture, the liquid level is a first preset distance from the gas-liquid separator to prevent the recovery storage part from exceeding the first limit liquid level threshold. Preferably, the height of the first anti-surge part or the height below the height is set as the first limit liquid level threshold. Preferably, the height of the lowest point of the first anti-surge part or the height below the height is set as the first limit liquid level threshold. The second limit liquid level threshold of the liquid level detection device is set as: when the recovery storage part is in a vertical posture with a parallel posture, the liquid level is a second preset distance from the gas-liquid separator to prevent the recovery storage part from exceeding the second limit liquid level threshold. Preferably, the height of the second anti-surge part or the height below the height is the second limit liquid level threshold. The liquid level detection device includes more than two liquid level detection parts, and at least two liquid level detection parts are arranged at the liquid level height of the first limit liquid level threshold; more preferably, the liquid level detection part is arranged below the liquid level height of the first limit liquid level threshold. Optionally, the liquid level detection device includes more than two liquid level detection parts, and at least two liquid level detection parts are arranged at the liquid level height of the second limit liquid level threshold. Optionally, the liquid level detection device includes more than two second liquid level detection parts, and one or more liquid level detection parts are arranged at the liquid level height of the second limit liquid level threshold; more preferably, one or more second liquid level detection parts are arranged below the liquid level height of the second limit liquid level threshold. In addition, it should be noted that the first liquid level detection part can be reused with the second liquid level detection part. Through the arrangement of these first liquid level detection parts and the second liquid level detection parts, accurate detection can be performed in corresponding postures respectively to avoid detection interference caused by liquid shaking.

[0113] In addition, when the liquid level in the recovery storage unit 400 is obtained, it is also possible to control whether to interrupt the recovery system according to the detected liquid level, thereby shutting down the surface cleaning device, etc. The liquid detection unit 405 can be any suitable detection device or element, etc. In the present disclosure, the liquid level detection unit can be in the form of a sensor, for example, in the form of a metal probe. The following will be described using a metal probe as an example, but those skilled in the art should understand that other detection components can be used.

[0114] The metal probe piece may be arranged on the inner side or the outer side of the recovery storage part 400, and preferably may be arranged on the outer side of the recovery storage part 400. And in the present disclosure, it is more preferred to arrange the metal probe piece on the side of the recovery storage part 400 facing the frame body. The number of metal probe pieces may be set to two or other numbers, and the number of metal probe pieces is selected to be able to detect the liquid level of the recovery liquid at least in the upright posture and the parallel posture, and more preferably also in the inclined use posture.

[0115] According to one embodiment, Fig.24 and Fig.25 As shown ( Fig.24 A schematic diagram showing the recovery storage unit 400 in an upright position, Fig.25 The schematic diagram of the recovery storage unit 400 in a parallel posture is shown), and four or more liquid level detection units (metal detectors) can be provided, and the four or more liquid level detection units can be arranged in rows and columns. For example, in the case of four as shown in the figure, the four liquid level detection units can be arranged in two rows and two columns. Although it is described here as an arrangement, it can also be an irregular shape.

[0116] For example, when detecting the liquid level of the recovered liquid in an upright posture, the height of the liquid level can be obtained by two rows of liquid level detection parts. Of course, it should be understood by those skilled in the art that more liquid level detection parts can be provided to obtain higher accuracy. For example, when measuring the liquid level of the recovery storage part 400 in an upright posture, the liquid level measurement can be performed by a group of liquid level detection parts arranged along the height direction of the recovery storage part 400. In addition, the uppermost liquid level detection device can be arranged at the capacity threshold position of the recovery storage part 400 to prevent the liquid from exceeding the threshold height. When the threshold height is reached, the surface cleaning device can alarm to remind the user to handle it.

[0117] When the liquid level of the recovered liquid is detected in a parallel posture, the height of the liquid level can also be obtained by two rows of liquid level detection parts. For example, when measuring the liquid level of the recovery storage part 400 in an upright posture, the liquid level measurement can be performed by a group of liquid level detection parts arranged along the thickness direction of the recovery storage part 400. Optionally, the uppermost liquid level detection device can be arranged at the capacity threshold position of the recovery storage part 400 to prevent the liquid from exceeding the threshold height. When the threshold height is reached, the surface cleaning device can alarm to remind the user to handle it. For example, the threshold height can be a height lower than the opening end of the recovery conduit (whether it is an upright posture, an inclined use posture or a parallel posture).

[0118] In addition, when detecting the liquid level of the recovered liquid in an inclined usage posture, detection can also be performed by using liquid level detection devices arranged in an array.

[0119] In addition, the liquid level detection device can also be used to detect whether the recovery storage part 400 exists on the surface cleaning device. For example, the liquid level detection device can cooperate with the sensing device provided on the frame of the main body 200. For example, if there is a mutual sensing signal between the two, it is considered that the recovery storage part 400 exists on the surface cleaning device.

[0120] Continuing to take the metal probe piece as an example, the metal probe piece is arranged on the side of the recovery storage part 400 facing the frame body, and a conductive sheet can be arranged on the frame body. When the recovery storage part 400 is installed, the conductive sheet can supply power to the metal probe piece, so that the metal probe piece can detect the liquid level and / or the existence of the recovery storage part 400. Although the metal probe piece and the conductive sheet are used as examples for explanation here, it should be understood that the two can adopt any other suitable forms.

[0121] In addition, the liquid level detection unit and the detection unit for detecting whether the recovery storage unit 400 exists can also be set separately, that is, independent detection methods are used for the two functions. In addition, more than two groups of detection units can be set to respectively implement the two detection functions.

[0122] In addition, if Fig.26 As shown, an electric circuit accommodating portion 230 may also be provided in the space between the cleaning liquid storage portion 300 and the recovery storage portion 400. The electric circuit accommodating portion 230 may be provided in the frame body 220, for example, may be fixed to the frame body 220. The electric circuit accommodating portion 230 may extend from the entire height of the cleaning liquid storage portion 300 and the recovery storage portion 400, or extend from the lower ends of the cleaning liquid storage portion 300 and the recovery storage portion 400 to the vicinity of the control circuit portion 700 and / or the power supply portion 800.

[0123] The electric line accommodating portion 230 may be in a long strip shape with a groove, and a power supply line, a control line, etc. may be accommodated in the electric line accommodating portion 230 , thereby achieving electrical communication with the cleaning base 600 .

[0124] In addition, as an optional implementation, a receiving portion in the form of a groove or the like may be provided on the frame body 220 to serve as the above-mentioned electric circuit receiving portion 230 . In addition, the above-mentioned conductive sheet may also be provided on the electric circuit receiving portion 230 .

[0125] In the present disclosure, the detection part of the liquid level detection device is close to the rear of the surface cleaning device relative to the recovery duct. The detection part of the liquid level detection device is one or more detection parts arranged from the outlet of the recovery duct to the rear of the surface cleaning device, so as to detect the liquid level of the recovery liquid of the recovery storage part when it is in at least one of the intermediate postures of the parallel posture and the self-supporting posture. The detection part communicates with the inside and outside of the recovery box, for example, it can penetrate the wall of the recovery storage part. As shown in the figure, the detection part may include a first arrangement and a second arrangement, and the first arrangement and the second arrangement are arranged along the longitudinal direction of the surface cleaning device. Preferably, the first arrangement includes at least the first probe point and the second probe point, and the second arrangement includes at least the third probe point and the fourth probe point, and electrical communication can be achieved between the first probe point to the fourth probe point. When in a parallel posture, the first probe point and the third probe point, or the second probe point and the fourth probe point are connected; when in a vertical posture and / or a self-supporting posture, the first probe point and the second probe point, or the third probe point and the fourth probe point are connected.

[0126] When the surface cleaning device performs suction operation, the suction source 460 located downstream performs suction operation, and gas is sucked from the exhaust port 408 and then discharged from the surface cleaning device. Upstream of the suction source 460 is the recovery storage unit 400, and the recovery conduit 440 in the recovery storage unit 400 receives the recovery liquid, gas and solids sucked from the cleaning base 600 from the outlet 506, and the recovery conduit 440 imports the recovery material into the recovery storage unit 400, and the liquid and solid are left in the recovery storage unit 400, and the gas is discharged from the exhaust port 408 via the gas channel by the gas-liquid separator 422. In addition, one or more additional filters can be set in the gas channel. For example, an additional filter can be set downstream of the suction source 460, and / or an additional filter can be set between its upstream and the recovery storage unit 400.

[0127] Fig. 27 A schematic diagram of a cleaning base according to one embodiment of the present disclosure is shown. Fig.28 A schematic diagram showing another angle of a cleaning base according to an embodiment of the present disclosure is shown. Fig.29 A schematic diagram of the internal structure of a cleaning base according to an embodiment of the present disclosure is shown.

[0128] The surface cleaning apparatus of the present disclosure may include Fig. 27 The cleaning base 600 shown. The cleaning base 600 can be used as a cleaning component of a surface cleaning device.

[0129] According to an embodiment of the present disclosure, a cleaning base 600, such as Figure 27 to Figure 29As shown, it includes: a cleaning module 610, the cleaning module 610 includes a cleaning surface, and the cleaning surface can be driven to contact the surface of the surface to be cleaned; a fluid distribution module 620, the fluid distribution module 620 is used to provide a predetermined amount of cleaning liquid to the cleaning module 610, so that the cleaning liquid is provided to the surface to be cleaned through the movement of the cleaning surface of the cleaning module 610, so that the cleaning base 600 performs wet cleaning on the surface to be cleaned; and a dirt suction module 630, the dirt suction module 630 is provided with negative pressure, so as to collect and suck dirt (such as dust and hair, etc.) after the cleaning module 610 cleans the surface to be cleaned and suck it into the dirt suction module 630, so as to prevent the cleaning base 600 from leaving stains such as the cleaning liquid after use on the surface to be cleaned after cleaning the surface to be cleaned. Of course, when the fluid distribution module 620 does not provide the cleaning liquid to the cleaning module 610, the surface cleaning device can also perform dry cleaning on the surface to be cleaned.

[0130] like Fig.29 As shown, the cleaning base 600 according to one embodiment of the present disclosure further includes: an installation joint module 640, and the cleaning base 600 is connected to the main body 200 by connecting the installation joint module 640 to the connecting part 500, so that when operating the surface cleaning device, at least a portion of the cleaning module 610 of the cleaning base 600 can contact the surface to be cleaned, thereby achieving cleaning of the surface to be cleaned.

[0131] like Figure 27 to Figure 29 As shown, the cleaning base 600 also includes a shell module 650, and the mounting joint module 640 can be rotatably disposed on the shell module 650. The shell module 650 forms at least a portion of the outer surface of the cleaning base 600 and can provide support for the above-mentioned cleaning module 610, fluid distribution module 620 and fluid distribution module 620.

[0132] The cleaning module 610 may be disposed at the front of the housing module 650 and accommodated in a brush chamber formed by the housing module 650 .

[0133] like Figure 27 to Figure 29 As shown, the cleaning base 600 also includes a moving wheel module 660, which is connected to the shell module 650. When the surface cleaning device is working, the moving wheel module 660 contacts the surface to be cleaned and rolls on the surface to be cleaned to reduce the power required for moving the surface cleaning device, and can also effectively prevent the cleaning base 600 from contaminating the cleaned surface.

[0134] The cleaning base 600 of the present disclosure is described in detail below with reference to the accompanying drawings.

[0135] Fig.30 A schematic structural diagram of a cleaning module according to an embodiment of the present disclosure is shown. Fig.31 Shows Fig.30 Schematic diagram of a cleaning module installed in a housing module. Fig.32 A schematic structural diagram of a cleaning module according to another embodiment of the present disclosure is shown. Fig.33 Shows Fig.32 Schematic diagram of a cleaning module installed in a housing module.

[0136] like Figure 30 to Figure 33 As shown, the cleaning module 610 includes a cleaning portion 611 and a cleaning drive device 612. The cleaning drive device 612 is disposed in the housing module 650 and is used to drive the cleaning portion 611 to rotate so that the cleaning portion 611 is in frictional contact with the surface to be cleaned, thereby allowing the cleaning portion 611 to clean the surface to be cleaned.

[0137] The cleaning part 611 includes: a first rotating part 6111 and an annular member 6112, wherein the cleaning driving device 612 is used to drive the first rotating part 6111 to rotate, and when the first rotating part 6111 rotates, the annular member 6112 is driven to move, so that the annular member 6112 and the surface to be cleaned generate relative movement to achieve cleaning of the surface to be cleaned.

[0138] Among them, Figure 30 to Figure 33 As shown, the cleaning drive device 612 is arranged outside the first rotating part 6111. Of course, the cleaning drive device 612 can also be arranged inside the first rotating part 6111, thereby enabling the cleaning base 600 to have a smaller volume, thereby being able to adapt to cleaning the surface to be cleaned in a smaller space.

[0139] The cleaning drive device 612 can be a motor, such as a DC motor, a stepping motor, etc. The DC motor is preferably a brushless DC motor. When the cleaning drive device 612 is located outside the first rotating part 6111, as shown in FIG. Figure 30 to Figure 33 As shown, the cleaning drive device 612 is connected to the first rotating part 6111 through the transmission assembly 613, and transmits the power generated by the cleaning drive device 612 to the first rotating part 6111, so that the first rotating part 6111 rotates. The transmission assembly 613 can be a belt transmission assembly, a chain transmission assembly, a gear transmission assembly, etc. In the present disclosure, the belt transmission assembly is preferably a synchronous belt transmission assembly.

[0140] Specifically, the cleaning drive device 612 is fixed to the shell module 650, for example, fixed to the mounting portion 651 of the shell module 650, and the cleaning drive device 612 is installed with an active synchronous pulley, and the active synchronous pulley and the cleaning drive device 612 are respectively located on both sides of the mounting portion 651, that is, the cleaning drive device 612 is located on the inner side of the mounting portion 651, and the active synchronous pulley is located on the outer side of the mounting portion 651; wherein the mounting portion 651 is formed by extending forward from the shell module 650.

[0141] The shell module 650 is formed with a accommodating portion (brush chamber), and the annular belt cleaning device is arranged on the bracket portion 618. When the bracket portion 618 is installed on the shell module 650, the annular belt cleaning device is located in the accommodating portion of the shell module 650; when the bracket portion is removed from the shell module, the annular belt cleaning device is removed from the shell module.

[0142] Of course, the mounting portion 651 may also be formed separately from the housing module 650 and fixed to the housing module 650, or detachably disposed on the housing module 650, so that the cleaning module 610 can be more conveniently disassembled. One end of the first rotating portion 6111 is rotatably disposed on the housing module 650, for example, rotatably disposed on the mounting portion 651 of the housing module 650, and the cleaning drive device 612 drives the first rotating portion 6111 to rotate via the transmission shaft 614 described below.

[0143] In the present disclosure, the cleaning module 610 further includes a transmission shaft 614, which is rotatably disposed on the housing module 650, for example, rotatably disposed on the mounting portion 651 of the housing module 650. A transmission member such as a driven synchronous pulley is disposed at one end of the transmission shaft 614, and the driven synchronous pulley is connected to the driving synchronous pulley in a transmission manner. Of course, the driving synchronous pulley and the driven synchronous pulley can also be replaced by gears, sprockets, pulleys, etc., which can be accomplished by those skilled in the art according to their technical common sense, and the present disclosure will not be described in detail one by one.

[0144] The other end of the transmission shaft 614 is inserted into the interior of the first rotating part 6111 and is connected to the first rotating part 6111 in transmission connection; on the one hand, the transmission shaft 614 can be directly connected to the first rotating part 6111, and at this time, the transmission shaft 614 and the first rotating part 6111 rotate at the same speed; of course, the transmission shaft 614 can also be indirectly connected to the first rotating part 6111 through a speed change device 615, and the speed change device 615 can be formed as a part of the cleaning drive device 612, or the cleaning drive device 612 can include the speed change device 615. At this time, preferably, the housing of the speed change device 615 can be fixed to the mounting part 651, and the rotation speed of the transmission shaft 614 is greater than the rotation speed of the first rotating part 6111; more preferably, the transmission shaft 614 can also be a part of the cleaning drive device 612, that is, the cleaning drive device 612 can also include the transmission shaft 614.

[0145] When the transmission shaft 614 is directly connected to the first rotating part 6111, the other end of the transmission shaft 614 is connected to the first drive connector 616, and the first drive connector 616 includes at least one key portion. For example, the first drive connector 616 can be formed as a spline shaft; accordingly, a second drive connector 617 is fixed inside the first rotating part 6111, and the second drive connector 617 is formed with a groove portion that cooperates with the first drive connector 616. When the key portion of the first drive connector 616 is inserted into the groove portion of the second drive connector 617, the first drive connector 616 drives the second drive connector 617 to rotate.

[0146] Of course, correspondingly, the first drive connector 616 can be formed with a groove portion. In this case, the second drive connector 617 includes at least one key portion. The transmission connection between the first drive connector 616 and the second drive connector 617 is achieved through the cooperation between the key portion of the second drive connector 617 and the groove portion of the first drive connector 616.

[0147] The other end of the first rotating part 6111 is rotatably disposed on the bracket part 618, wherein the bracket part 618 is connected to the housing module 650. Preferably, the bracket part 618 is detachably connected to the housing module 650, so that when the bracket part 618 is removed from the housing module 650, the cleaning module 610 can be maintained or cleaned. Specifically, the bracket part includes a mechanical connector corresponding to the housing module, and when the bracket part is connected to the housing module matched therewith, the mechanical connector is aligned with the matching connector of the housing module at the same time. And the bracket part 618 is at least connected to the first rotating part, and when the bracket part is installed in the housing module, at least part of the cleaning drive device slides into the first rotating part; more specifically, when the bracket part is installed in the housing module, the speed change device slides into the inner cavity of the first rotating part, and realizes the mechanical connection between the speed change device and the first rotating part.

[0148] like Fig.30 and Fig.31 As shown, when the cleaning module 610 only includes the first rotating portion 6111 and the ring member 6112 disposed outside the first rotating portion 6111, the cleaning module 610 is formed in the form of a roller brush. Fig.32 and Fig.33 As shown, the cleaning module 610 can also be formed in the form of an annular belt cleaning device. In this case, the cleaning module 610 also includes a second rotating part 6113, which is arranged parallel to the first rotating part 6111, and one end of the second rotating part 6113 can also be rotatably arranged on the shell module 650.

[0149] The annular member 6112 is disposed to wrap the first rotating portion 6111 and the second rotating portion 6113 , and the annular member 6112 located below the first rotating portion 6111 and the second rotating portion 6113 is in contact with the surface to be cleaned.

[0150] The outer diameters of the first rotating portion 6111 and the second rotating portion 6113 may be the same or different. When the outer diameters of the first rotating portion 6111 and the second rotating portion 6113 are different, preferably, the diameter of the first rotating portion 6111 is greater than the diameter of the second rotating portion 6113.

[0151] The cleaning surface is located on the annular member 6112 , and the annular member transmits power between the first rotating part 6111 and the second rotating part 6113 .

[0152] Taking the movement direction of the surface cleaning equipment to clean the surface to be cleaned as the forward direction, the second rotating part 6113 is arranged in front of the first rotating part 6111, that is, the first rotating part 6111 is close to the rear side of the cleaning module, and the second rotating part 6113 is close to the front side of the cleaning module; of course, the second rotating part 6113 can also be arranged behind the first rotating part 6111, and technicians in this field can adjust the position of the second rotating part 6113 based on their technical common sense.

[0153] like Fig.32 and Fig.33 As shown, further, the other end of the second rotating portion 6113 can also be rotatably disposed on the bracket portion 618, so that the first rotating portion 6111 and the second rotating portion 6113 are rotatably supported by the bracket portion 618. When the cleaning module 610 includes the first rotating portion 6111 and the second rotating portion 6113, that is, when the cleaning module 610 is formed as an endless belt type cleaning device, the annular member 6112 is formed as a flexible annular belt portion.

[0154] Fig.34 FIG. 6 is a schematic diagram showing the structure of a cleaning module 610 according to another embodiment of the present disclosure. Fig.34 As shown, the cleaning drive device 612 can be arranged inside the first rotating part 6111. At this time, one end of the first rotating part 6111 can be rotatably arranged on the shell module 650, for example, can be rotatably arranged on the mounting part 651 of the shell module 650; the other end of the first rotating part 6111 can be rotatably arranged on the bracket part 618.

[0155] Accordingly, when the cleaning drive device 612 is located inside the first rotating part 6111, since there is no transmission member such as a synchronous belt, the edge distance of the cleaning base 600 is reduced to a smaller value. Fig.34As shown, the value of the edge cleaning distance X depends only on the thickness of the bracket portion 618, and the value of the edge cleaning distance Y depends only on the thickness of the mounting portion 651. Since there is no need to install a synchronous belt, the installation of a wide synchronous belt to reduce the edge performance is avoided.

[0156] The cleaning drive device 612 is fixed to the mounting portion 651 , and the cleaning drive device 612 may be connected to a speed change device 615 . Of course, when the cleaning drive device 612 is selected as a reduction motor, the speed change device 615 may not be used, and the power of the cleaning drive device 612 may be directly transmitted to the first drive connector 616 .

[0157] The speed change device 615 is connected to the first drive connector 616 to transmit the driving force to the first drive connector; moreover, the first drive connector 616 is transmission-connected to the second drive connector 617. When the second drive connector 617 is fixed to the first rotating part 6111, the driving force can be provided to the first rotating part 6111, thereby causing the first rotating part 6111 to rotate.

[0158] On the other hand, a first support member 6191 is disposed inside the other end of the first rotating portion 6111. For example, the inner wall surface of the first rotating portion 6111 is fixed to the outer wall surface of the first support member 6191. A second support member 6192 is disposed inside the first support member 6191. The second support member 6192 is detachable relative to the first support member 6191, that is, the second support member 6192 can be removed from the first support member 6191.

[0159] The support portion 6193 passes through the bracket portion 618 and is fixed to the second support member 6192 , and a bearing is provided between the support portion 6193 and the bracket portion 618 so that the support portion 6193 is rotatably supported on the bracket portion 618 through the bearing and the first rotating portion 6111 can rotate relative to the bracket portion 618 .

[0160] By adopting a similar structure, the two ends of the second rotating portion 6111 can be rotatably disposed on the bracket portion 618 and the mounting portion 651 respectively, which will not be described in detail here.

[0161] Fig.35 A schematic structural diagram of a first rotating part according to an embodiment of the present disclosure is shown. Fig.36 FIG. 6 is a schematic diagram showing the structure of a ring member according to an embodiment of the present disclosure. In order to prevent the ring member 6112 from being separated from the first rotating part 6111 and / or the second rotating part 6113, as shown in FIG. Fig.35As shown, at least one end of the first rotating part 6111 and / or the second rotating part 6113 is formed with an outer flange part 6111A, and preferably, both ends of the first rotating part 6111 and / or the second rotating part 6113 are formed with outer flange parts 6111A, so as to restrict the annular member 6112 between the two outer flange parts 6111A.

[0162] Furthermore, in order to prevent the ring member 6112 from slipping on the first rotating portion 6111 and / or the second rotating portion 6113, as Fig.35 As shown, an outer tooth portion 6111B is formed on the circumferential surface of at least one of the first rotating portion 6111 and / or the second rotating portion 6113; correspondingly, an inner tooth portion is formed on the inner circumferential surface of the ring member 6112, so that the ring member 6112 is effectively prevented from slipping through the cooperation between the outer tooth portion 6111B and the inner tooth portion, thereby improving the efficiency of cleaning the surface to be cleaned.

[0163] Furthermore, considering that the first rotating portion 6111 and / or the second rotating portion 6113 are relatively long, in order to prevent the flexible annular belt portion from folding, etc., Fig.35 As shown, at least one annular groove 6111C is formed on the outer circumferential surface of the first rotating portion 6111 and / or the second rotating portion 6113, so that the first rotating portion 6111 and the second rotating portion 6113 are divided into multiple parts along the axial direction through the annular groove 6111C.

[0164] Furthermore, Fig.35 As shown, at least one of the two sides of the annular groove 6111C is respectively provided with an annular protrusion 6111D, and more preferably, an annular protrusion 6111D is provided on both sides of the annular groove 6111C, wherein the inner tooth portion is formed in the area between the two annular grooves 6111C and the area between the annular groove 6111C and the outer flange portion 6111A.

[0165] Correspondingly, corresponding to the parts of the annular groove 6111C and the annular protrusion 6111D, the inner surface of the annular member 6112 forms an annular protrusion 6111D and an annular groove 6111C, so that the annular protrusion 6111D of the annular member 6112 cooperates with the annular groove 6111C of the first rotating part 6111 and / or the second rotating part 6113, and the annular groove 6111C of the annular member 6112 cooperates with the annular protrusion 6111D of the first rotating part 6111 and / or the second rotating part 6113.

[0166] Fig.37 A schematic structural diagram of a first rotating portion 6111 according to another embodiment of the present disclosure is shown. Fig.38A schematic diagram of the structure of the annular member 6112 according to another embodiment of the present disclosure is shown. In the present disclosure, in another case, a soft rubber layer 6111E is provided in the area between the two annular grooves 6111C and / or between the annular groove 6111C and the outer flange portion 6111A, so as to increase the friction between the first rotating part 6111 and the annular member 6112 through the soft rubber layer 6111E, and prevent the relative sliding between the annular member 6112 and the first rotating part 6111. More preferably, the soft rubber layer 6111E can be made of natural or synthetic rubber, such as ethylene propylene diene monomer rubber (EPDM) or nitrile rubber, or a soft material such as silicone. On the other hand, an outer tooth portion 6111B can also be provided on the soft rubber layer 6111E, so as to further prevent the relative sliding between the first rotating part 6111 and the annular member 6112 through the soft rubber layer 6111E having the outer tooth portion 6111B.

[0167] Fig.39 Shows Fig.37 Schematic cross-sectional view of . Fig.40 Shows Fig.38 Schematic cross-sectional view of Fig.39 and Fig.40 As shown, the radial dimensions of the outer flange portions 6111A at both ends of the first rotating portion 6111 and / or the second rotating portion 6113 of the present invention are smaller than the thickness of the annular member 6112, so that when the cleaning module 610 is performing a cleaning operation, the outer flange portions 6111A of the first rotating portion 6111 and / or the second rotating portion 6113 will not contact the surface to be cleaned, thereby effectively preventing the first rotating portion 6111 and / or the second rotating portion 6113 from damaging the surface to be cleaned and also improving the cleaning effect.

[0168] Considering that the structures of the second rotating part 6113 and the first rotating part 6111 of the present disclosure are similar, those skilled in the art can know the structure of the second rotating part 6113 based on the structure of the first rotating part 6111 , and based on this, the present disclosure no longer provides illustrations of the second rotating part 6113 .

[0169] Fig.41A schematic diagram of the preparation process of an annular member according to an embodiment of the present disclosure is shown. In the present disclosure, the annular member 6112 is an important component of the cleaning operation. When the surface cleaning device is used for cleaning operations, the flexible annular belt portion is in direct contact with the surface to be cleaned. Preferably, the annular member 6112 includes a cleaning body 6112A and a substrate 6112B. The cleaning body 6112A is similar to the cleaning body 6112A of an ordinary floor brush, and a rag-like fluff material can be selected. The substrate 6112B is generally a flexible soft material, and the cleaning body 6112A can be fixed on the substrate 6112B by gluing, sewing, etc., so that the entire annular member 6112 is attached to the first rotating part 6111, or attached to the first rotating part 6111 and the second rotating part 6113 which are parallel to each other.

[0170] Considering the particularity of the annular member 6112 of the present disclosure, the present disclosure provides a method for preparing the annular member 6112, which includes: S601, using a flexible material to prepare a substrate 6112B, wherein the cross section of the substrate 6112B is annular. Wherein, the flexible material for preparing the substrate 6112B can be a material such as rubber, fiber cloth, etc., so that the annular member 6112 can play an effect similar to a conveyor belt. S602, using at least two tensioning rollers to tension the above-mentioned substrate 6112B, and applying an adhesive to the outer peripheral surface of the substrate 6112B. In the present disclosure, at least one of the tensioning rollers can be driven to rotate, so that the substrate 6112B moves on the tensioning roller, thereby conveniently applying an adhesive to the outer surface of the substrate 6112B. S603, applying an adhesive on one surface of the cleaning body 6112A, and placing the cleaning body 6112A on the substrate 6112B, when the adhesive is cured, the substrate 6112B is removed from the tensioning roller, and the annular member 6112 is obtained.

[0171] Those skilled in the art should know that after the outer surface of the tension roller is applied with adhesive, the surface of the cleaning body 6112A does not need to be applied with adhesive. In other words, adhesive can be applied only on the outer peripheral surface of the tension roller and one surface of the cleaning body 6112A. However, in order to make the ring member 6112 have a better cleaning effect, the ring member 6112 of the present disclosure has adhesive applied on the outer peripheral surface of the tension roller and the surface of the ring member 6112 during the manufacturing process.

[0172] More preferably, in order to improve the service life of the ring member 6112 and prevent the base material 6112B of the ring member 6112 from separating from the ring member 6112, the circumferential direction of at least one end of the ring member 6112 in the present disclosure is sutured by a suture line 6112C, that is, at least one end of the cleaning body is re-fixed with at least one open end of the base material, thereby, when the ring member 6112 of the present disclosure is used, the conventional end cap compression method can be avoided, thereby reducing the cleaning-to-edge distance of the cleaning body 6112A. More preferably, both ends of the cleaning body 6112A are sutured by a suture line 6112C.

[0173] Fig.42 A schematic diagram of a ring-shaped member prepared according to one embodiment of the present disclosure is shown. Fig.43 A cross-sectional schematic diagram of a ring according to one embodiment of the present disclosure is shown. Fig.44 FIG. 2 shows a cross-sectional schematic diagram of a ring member according to another embodiment of the present disclosure. Fig.42 and Fig.43 As shown, in order to prevent the ends of the sutures 6112C on both sides from causing the bulge of the annular member 6112 when the annular member 6112 is installed to the first rotating part 6111 or the second rotating part 6113, thereby increasing the risk of the flexible annular belt portion falling off the first rotating part 6111 or the second rotating part 6113, in the present disclosure, grooves can be provided on the outer circumferential surfaces of the first rotating part 6111 and the second rotating part 6113 relative to the position of the sutures 6112C, so as to accommodate the sutures 6112C and the ends of the sutures 6112C through the grooves; accordingly, when the grooves are formed on the first rotating part 6111 and the second rotating part 6113, the grooves on the first rotating part 6111 and the second rotating part 6113 are annular mounting grooves.

[0174] In addition, if Fig.44 As shown, a groove may also be formed on the inner circumferential surface of the substrate 6112B so that the suture 6112C is located in the groove; more preferably, when a groove is formed on the inner circumferential surface of the substrate 6112B, the groove may be formed as an annular mounting groove, or may not be formed as an annular mounting groove. For example, the groove formed on the substrate 6112B is formed in the shape of a blind hole to accommodate the joint of the suture 6112C through the blind hole.

[0175] The structural schematic diagram of the detachable endless belt cleaning assembly disclosed in the present invention is described below in conjunction with the accompanying drawings. Fig.45 A schematic diagram of a removable endless belt cleaning assembly according to one embodiment of the present disclosure is shown. Fig.46 A schematic diagram showing another angle of a detachable endless belt cleaning assembly according to an embodiment of the present disclosure is shown.

[0176] When the cleaning module 610 is a roller brush, the roller brush can be disassembled by disassembling the first rotating portion 6111 of the roller brush.

[0177] For endless belt cleaning devices, such as Fig.45 and Fig.46 As shown, the present disclosure also includes a detachable annular belt cleaning assembly, which includes: a bracket portion 618, which is detachably disposed on the housing module 650; and an annular belt cleaning device, which is disposed on the bracket portion 618, and when the bracket portion 618 is detached from the housing module 650, the annular belt cleaning device is detached from the housing module 650.

[0178] The annular belt cleaning device comprises: a rotating shaft assembly and a flexible annular belt portion, wherein the flexible annular belt portion wraps the rotating shaft assembly and is driven by the rotating shaft assembly to move the flexible annular belt portion so as to clean the surface to be cleaned through the flexible annular belt portion.

[0179] pass Fig.45 and Fig.46 The content shown shows the effect after the detachable endless belt cleaning assembly is removed from the housing module 650.

[0180] The cleaning drive device 612 is used to drive the shaft assembly to rotate, wherein the cleaning drive device 612 is arranged outside the shaft assembly, and of course, the cleaning drive device 612 can also be arranged inside the shaft assembly, thereby enabling the cleaning base 600 to have a smaller volume, so as to be able to adapt to cleaning the surface to be cleaned in a smaller space. The shaft assembly includes a first rotating portion 6111 and a second rotating portion 6113, and the structures and positional relationship of the first rotating portion 6111 and the second rotating portion 6113 are described above, and will not be repeated here.

[0181] In order to conveniently install the detachable annular belt cleaning assembly on the housing module 650, a first support bearing and a second support bearing are arranged on the mounting portion 651. For example, the inner ring of the first support bearing is arranged on the mounting portion 651. Preferably, the first support bearing can be arranged on the transmission shaft 614. For example, the inner ring of the first support bearing can be sleeved and fixed on the transmission shaft 614. Thus, when the detachable annular belt cleaning assembly is installed on the housing module 650, one end of the first rotating portion 6111 of the rotating shaft assembly can be rotatably supported on the first support bearing. For example, the inner wall surface of one end of the first rotating portion 6111 can be detachably arranged on the outer ring of the first support bearing, or, the inner wall surface of one end of the first rotating portion 6111 can be slidably arranged on the outer ring of the first support bearing.

[0182] Similarly, the inner ring of the second support bearing is arranged on the mounting portion 651. Preferably, the inner ring of the second support bearing can be fixed to the mounting portion 651. When the detachable annular belt cleaning assembly is installed on the housing module 650, one end of the second rotating portion 6113 is rotatably supported on the second support bearing; for example, the inner wall surface of one end of the second rotating portion 6113 is arranged on the outer ring of the second support bearing, or in other words, the inner wall surface of one end of the second rotating portion 6113 is slidably arranged on the outer ring of the second support bearing.

[0183] Fig.47 FIG. 2 shows a schematic diagram of a flexible annular belt portion being disassembled according to an embodiment of the present disclosure. Fig.47 As shown, after the detachable annular belt cleaning assembly is detached from the housing module 650 , the flexible annular belt portion can be detached from the first rotating portion 6111 and the second rotating portion 6113 to facilitate cleaning or replacement.

[0184] Fig.48 FIG. 2 shows a schematic diagram of the first rotating part 6111 and the second rotating part 6113 being disassembled according to an embodiment of the present disclosure. Fig.48 As shown, at least one of the first rotating portion 6111 and the second rotating portion 6113 can be detached from the bracket portion 618 to prevent hair from being present between the bracket portion 618 and the shaft assembly, thereby facilitating cleaning by a user.

[0185] Correspondingly, a third support bearing and a fourth support bearing are arranged on the bracket portion 618. For example, the inner ring of the third support bearing is arranged on the bracket portion 618, and the other end of the first rotating portion 6111 of the shaft assembly is rotatably supported on the third support bearing. For example, the inner wall surface of the other end of the first rotating portion 6111 is detachably arranged on the outer ring of the third support bearing, or in other words, the inner wall surface of the other end of the first rotating portion 6111 is slidably arranged on the outer ring of the third support bearing.

[0186] Similarly, the inner ring of the fourth support bearing is arranged on the bracket part 618. Preferably, the inner ring of the fourth support bearing can be fixed to the bracket part 618, and the other end of the second rotating part 6113 can be rotatably supported on the fourth support bearing; for example, the inner wall surface of the other end of the second rotating part 6113 is arranged on the outer ring of the fourth support bearing, or, the inner wall surface of the other end of the second rotating part 6113 can be slidably arranged on the outer ring of the fourth support bearing.

[0187] Fig.49 FIG. 2 shows a schematic diagram of a first rotating part and a second rotating part being installed according to an embodiment of the present disclosure. Fig.49As shown, when the detachable annular belt cleaning assembly is installed on the housing module 650, considering that the flexible annular belt portion is in a tensioned state, the first rotating portion 6111 and the second rotating portion 6113 will approach each other under the action of the force exerted by the flexible annular belt portion, resulting in the first rotating portion 6111 and the second rotating portion 6113 being unable to be strictly aligned with the first support bearing and the second support bearing, and the first rotating portion 6111 and the second rotating portion 6113 need to maintain an interference fit with the first support bearing and the second support bearing respectively. These factors lead to difficulties in installation, and users have a poor experience when cleaning and replacing the annular belt and when assembling and disassembling the entire cleaning annular belt assembly.

[0188] Fig.50 A schematic diagram of the mounting position of a retainer according to an embodiment of the present disclosure is shown. Fig.51 FIG. 1 shows a schematic diagram of a retainer in a separated state according to an embodiment of the present disclosure. Fig.50 and Fig.51 As shown, the detachable annular belt cleaning assembly also includes a retaining frame 6114, which is arranged on the first rotating part 6111 and the second rotating part 6113 to limit the positions of the first rotating part 6111 and the second rotating part 6113 to prevent the first rotating part 6111 and the second rotating part 6113 from approaching each other.

[0189] Preferably, at least one holder 6114 is provided. When there is one holder 6114, the holder 6114 is provided at one end of the first rotating part 6111 and the second rotating part 6113 away from the bracket part 618; when there are two holders 6114, the holder 6114 can be provided at both ends of the first rotating part 6111 and the second rotating part 6113. That is, in the present disclosure, the flexible annular belt part can be made into a consumable material, and a holder 6114 can be installed on the other side of the bracket part 618 to avoid the first rotating part 6111 and the second rotating part 6113 being close to each other due to the tensioning effect of the flexible annular belt part, so that the entire detachable annular belt cleaning assembly can be easily installed on the surface cleaning device.

[0190] It is too expensive to make the entire detachable annular belt cleaning assembly into a consumable. Therefore, it is also possible to consider using the flexible annular belt portion and the retaining frame 6114 as consumables, and installing a retaining frame 6114 on each side of the cleaning annular belt, so that users can assemble and replace it more conveniently while reducing the cost.

[0191] Fig.52 FIG. 6 is a schematic diagram of a ring member 6112 according to an embodiment of the present disclosure. Fig.52As shown, the circumference of the outer circumference of the ring member 6112 of the present disclosure is greater than or equal to 20 cm, which can effectively solve the problem of hair entanglement in most usage environments. That is, since most of the hair that falls in the home environment is less than or equal to 20 cm in length, when the circumference of the outer circumference of the ring member 6112 is set to be greater than or equal to 20 cm, the hair cannot be entangled with the ring member 6112 for one circle, so that when the ring member 6112 moves, the hair and other stolen goods will be scraped off by the scraper and enter the sewage storage part through the dirt suction module 630.

[0192] Fig.53 FIG. 2 shows a schematic diagram of a cleaning base 600 cleaning a surface to be cleaned according to an embodiment of the present disclosure. Fig.53 As shown, when the cleaning base 600 is used to clean the surface to be cleaned, the speed for pushing the surface cleaning device forward on the surface to be cleaned is approximately 0.5 m / s. If the linear speed of the annular member 6112 is less than 0.5 m / s, it may not form a certain relative speed with the surface to be cleaned, thereby failing to allow the cleaning base 600 to clean the same position at least once in the process of pushing and pulling the surface cleaning device.

[0193] However, when the linear velocity of the flexible annular belt surface in contact with the surface to be cleaned is greater than or equal to 0.5 m / s (the direction of the linear velocity is backward), it can be ensured that the surface cleaning device cleans the preset area of ​​the surface to be cleaned at least once during use.

[0194] Fig.54 FIG. 6 is a schematic structural diagram of a cleaning base 600 according to another embodiment of the present disclosure. Fig.55 FIG. 6 is a schematic diagram showing a cleaning base 600 at another angle according to another embodiment of the present disclosure. Fig.56 The figure shows a schematic diagram of the internal structure of a cleaning base 600 according to another embodiment of the present disclosure. The moving wheel module 660 is disposed on the housing module 650, and the lowest point of the moving wheel module 660 is located below the lowest point of the housing module 650, so that when the surface cleaning device is working, the moving wheel module 660 contacts the surface to be cleaned and rolls on the surface to be cleaned, so as to reduce the power required for the surface cleaning device to move; the moving wheel module 660 is located at the rear side of the housing module 650, so as to effectively prevent the cleaning base 600 from contaminating the surface that has been cleaned.

[0195] On the one hand, if Figure 27 to Figure 29As shown, the moving wheel module 660 is integrally formed with the housing module 650, that is, the moving wheel module 660 includes: a moving wheel frame 661 and a moving wheel 662; wherein the moving wheel frame 661 is integrally formed with the housing module 650 and is located at the rear side of the housing module 650; and the moving wheel 662 is rotatably arranged on the moving wheel frame 661. In the present disclosure, the moving wheel frame 661 includes two mounting members 6611, and the number of the moving wheels 662 is two, that is, one moving wheel 662 is installed on each mounting member 6611, wherein the two mounting members 6611 are located between the two moving wheels 662, or in other words, the two moving wheels 662 are located on the outside of the two mounting members 6611. Of course, those skilled in the art should know that the moving wheel 662 can also be arranged on the inner side of the mounting member 6611.

[0196] On the other hand, Figure 54 to Figure 56 As shown, the moving wheel module 660 includes a moving wheel frame 661 and a moving wheel 662. The moving wheel frame 661 is formed separately from the housing module 650, and the housing module 650 is connected to the moving wheel frame 661, so that the housing module 650 can move relative to the moving wheel frame 661. For example, the housing module 650 has at least one rotational degree of freedom relative to the moving wheel frame 661, and preferably, the housing module 650 has two rotational degrees of freedom relative to the moving wheel frame 661, that is, a pitch degree of freedom (Y axis) and a roll degree of freedom (X axis).

[0197] The movable wheel frame 661 is described in detail below in conjunction with the accompanying drawings. Fig.55 As shown, the moving wheel frame 661 includes two mounting members 6611 and a connecting portion 6612 connecting the two mounting members 6611 .

[0198] There are two moving wheels 662, that is, one moving wheel 662 is installed on each mounting member 6611, wherein the two mounting members 6611 are located between the two moving wheels 662, or in other words, the two moving wheels 662 are located outside the two mounting members 6611. Of course, those skilled in the art should know that the moving wheel 662 can also be arranged on the inner side of the mounting member 6611.

[0199] The housing module 650 is formed with a connecting neck 652. In the present disclosure, the axis of the connecting neck 652 is arranged along the front-rear direction, and a rotating ring 663 is arranged outside the connecting neck 652, so that the connecting neck 652 can rotate in the rotating ring 663, so that the housing module 650 has a rolling degree of freedom. Moreover, the rotating ring 663 is rotatably arranged on the connecting portion 6612, wherein the rotating axis of the rotating ring 663 relative to the connecting portion 6612 is parallel to the rotating axis of the moving wheel 662, and is not on the same straight line, so that the housing module 650 has a pitching degree of freedom.

[0200] When the cleaning base 600 is in use, since the cleaning area of ​​the flexible annular belt is large, if the floor at home is uneven, a surface is determined by three points, which will inevitably cause the moving wheel 662 or the flexible annular belt to not be able to contact the ground at the same time. If only one end of the flexible annular belt is in contact with the ground, the other end will inevitably not be able to contact the ground well, resulting in unsatisfactory cleaning effect.

[0201] However, the shell module 650 and the moving wheel module 660 of the present invention are connected by a hinged manner, so that relative floating is formed between the shell module 650 and the moving wheel module 660, thereby adapting to uneven ground, ensuring effective contact between the flexible annular belt and the surface to be cleaned, and ensuring the cleaning effect.

[0202] like Figure 27 to Figure 29 The cleaning base 600 is installed on the connecting part of the surface cleaning device by installing the joint module 640, for example, it can be detachably installed on the main body of the surface cleaning device, so that when the surface cleaning device is operated, at least a portion of the cleaning base 600 can contact the surface to be cleaned, and when the cleaning base 600 is moved along a preset path, the surface to be cleaned is cleaned.

[0203] The mounting joint module 640 is rotatably disposed on the shell module 650 so that a preset angle can be formed between the surface cleaning device and the cleaning base 600. For example, when the surface cleaning device is in a non-working state, an angle of approximately 90° is formed between the surface cleaning device and the shell module 650 of the cleaning base 600, and the surface cleaning device is in an upright state; when the surface cleaning device is in a working state, an angle of greater than or equal to 120° is formed between the surface cleaning device and the shell module 650 of the cleaning base 600, and even the angle between the surface cleaning device and the shell module 650 can be 180°, that is, the surface cleaning device and the shell module 650 are both parallel to the surface to be cleaned, so that the surface cleaning device of the present disclosure can clean the surface to be cleaned under the sofa and the surface to be cleaned under the bed, etc.

[0204] Fig.57 and Fig.59 An exploded schematic diagram of a cleaning base 600 according to one embodiment of the present disclosure is shown. Fig.58 FIG. 6 is a schematic diagram showing a cleaning base 600 at another angle according to an embodiment of the present disclosure. Fig.60 FIG. 2 shows a schematic diagram of a cleaning base 600 according to another embodiment of the present disclosure. Figures 57 to 60 As shown, the fluid distribution module 620 of the cleaning base 600 of the present disclosure is disposed in the housing module 650 for providing cleaning liquid to the cleaning module 610, for example, to the endless belt cleaning device, so that the endless belt cleaning device can perform wet cleaning on the surface to be cleaned.

[0205] The fluid distribution module 620 includes a flow control unit 621 and a fluid distributor 622, wherein the flow control unit 621 is connected to the cleaning liquid storage unit of the surface cleaning device through a first liquid supply pipeline, and is used to provide the cleaning liquid stored in the cleaning liquid storage unit of the surface cleaning device to the fluid distributor 622 through the flow control unit 621.

[0206] The flow control unit 621 is connected to the fluid distributor 622 through a second liquid supply pipeline to uniformly provide cleaning liquid to the surface of the ring-shaped belt cleaning device and keep the ring-shaped belt cleaning device in a wet state so that it can be applied to the surface to be cleaned through the ring-shaped belt cleaning device, thereby improving the cleaning quality.

[0207] Among them, when the flow control unit 621 is directly connected to the fluid distributor 622, the second liquid supply pipeline may not be used; when a heating device is provided between the flow control unit 621 and the fluid distributor 622, the second liquid supply pipeline is used to connect the flow control unit 621 and the fluid distributor 622, and at this time, the heating device is provided in the second liquid supply pipeline.

[0208] In the present disclosure, the flow control unit 621 can be selected as a water pump, and the water pump is preferably a peristaltic pump, so as to better prevent liquid leakage through the peristaltic pump and more accurately control the flow provided to the fluid distributor 622, without setting valves such as one-way valves.

[0209] The flow control unit 621 is disposed in the housing module 650 and can be located inside the housing module 650 . The fluid distributor 622 is also disposed in the housing module 650 and is located at the rear side of the cleaning module 610 , such as an annular belt cleaning device.

[0210] In the present disclosure, the fluid distributor 622 is a labyrinth fluid distributor 622, so that the cleaning liquid is evenly distributed on the surface of the endless belt cleaning device. The cleaning base 600 also includes an upper shell 670, which is disposed on the housing module 650 and forms a part of the outer surface of the cleaning base 600 and at least partially covers the cleaning assembly; for example, the upper shell 670 is detachably disposed on the housing module 650, and preferably, the rear portion of the upper shell 670 is detachably disposed on the housing module 650, and the front portion of the upper shell 670 is located above the annular member 6112 and at least partially covers the annular member 6112.

[0211] like Fig.64 As shown, the fluid distributor 622 may include one or more water outlets, and the water outlets may be formed in the housing module 650 or in the upper housing 670. In one implementation, the plurality of water outlets form a row of structures.

[0212] The cleaning liquid flowing out through the water outlet to the surface of the annular member 6112 is evenly distributed on the surface of the annular member 6112 after passing through the brush plate portion 671 .

[0213] Among them, the brush plate part 671 is arranged on the upper shell 670, or is integrally formed with the upper shell 670. In one implementation form, the brush plate part 671 extends along the length direction of the cleaning module, and the two ends of the brush plate part 671 are not shorter than the two ends of the annular member.

[0214] More preferably, along the movement direction of the annular part of the cleaning module, the brush plate portion 671 is located on the downstream side of the fluid distributor 622, so that when the fluid distributor 622 provides cleaning liquid to the annular part of the cleaning module, the cleaning liquid is more evenly distributed on the surface of the annular part 6112 through the brush plate portion 671. At this time, the brush plate portion 671 is in contact with the surface of the annular part.

[0215] The fluid distributor 622 can be installed on the upper shell 670, or the fluid distributor 622 can be integrally formed with the upper shell 670 to provide cleaning liquid to the outer surface of the rear portion of the ring 6112, and as the ring 6112 moves, the cleaning liquid is applied to the surface to be cleaned.

[0216] There is a preset interval between the fluid distributor 622 and the surface of the ring-shaped belt cleaning device, wherein the size of the preset interval may vary according to the pressure of the cleaning liquid output by the flow control unit 621. For example, when the pressure of the cleaning liquid output by the flow control unit 621 is relatively high, the preset interval is also relatively high. Correspondingly, when the pressure of the cleaning liquid output by the flow control unit 621 is relatively low, the preset interval is also relatively low. When the cleaning module 610 is a ring-shaped belt cleaning device, if foreign matter enters the inner surface of the flexible ring-shaped belt portion, the foreign matter may enter between the flexible ring-shaped belt portion and the first rotating portion 6111, or enter the area between the flexible ring-shaped belt portion and the second rotating portion 6113, which may cause damage to the ring-shaped belt.

[0217] For this reason, Fig.57 and Fig.58 As shown, when the flexible annular belt portion is attached to the first rotating portion 6111 and the second rotating portion 6113, the upper edge of the mounting portion 651 is formed to be no lower than the lower surface of the upper portion of one end of the flexible annular belt portion, and the lower edge of the mounting portion 651 is formed to be no higher than the upper surface of the lower portion of one end of the flexible annular belt portion, so that the mounting portion 651 can close one end of the flexible annular belt portion.

[0218] Accordingly, the upper edge of the bracket portion 618 is formed to be no lower than the lower surface of the upper part of the other end of the flexible annular belt portion, and the lower edge of the bracket portion 618 is formed to be no higher than the upper surface of the lower part of the other end of the flexible annular belt portion, so that the bracket portion 618 can close the other end of the flexible annular belt portion.

[0219] Thus, by providing the mounting portion 651 and the bracket portion 618 , foreign matter can be effectively prevented from entering the interior of the flexible annular belt portion.

[0220] More preferably, in some implementations, the upper edge of the mounting portion 651 can be located below the lower surface of the upper portion of one end of the flexible annular band portion, and through the cooperation between the mounting portion 651 and the lower edge of the upper shell 670, one end of the flexible annular band portion is closed.

[0221] Correspondingly, the upper edge of the bracket portion 618 can also be located below the lower surface of the upper part of the other end of the flexible annular belt portion, and the other end of the flexible annular belt portion is closed by the cooperation between the bracket portion 618 and the lower edge of the upper shell 670.

[0222] Fig.61 FIG. 2 shows a cross-sectional schematic diagram of a cleaning base 600 according to an embodiment of the present disclosure. Fig.61 As shown, when the cleaning assembly is an annular belt cleaning device, the diameter of the first rotating portion 6111 or the second rotating portion 6113 located in front of the annular belt cleaning device is smaller. That is, when the first rotating portion 6111 is located in front of the second rotating portion 6113, the diameter of the first rotating portion 6111 is smaller than the diameter of the second rotating portion 6113, and when the second rotating portion 6113 is located in front of the first rotating portion 6111, the diameter of the second rotating portion 6113 is smaller than the diameter of the second rotating portion 6113.

[0224] In the present disclosure, the dirt suction module 630 is connected to the sewage storage part through the return liquid pipeline, so that when negative pressure is provided to the dirt suction module 630 through the sewage storage part, the dirt after the cleaning module 610 cleans the surface to be cleaned can be sucked into the sewage storage part through the dirt suction module 630. The dirt suction module 630 includes a suction port 631, which is located behind the cleaning module 610, and the suction port 631 can be formed integrally with the housing module 650. In other words, the housing module 650 forms the suction port 631. The dirt suction module 630 also includes a scraper portion 632, which contacts the flexible annular belt portion so that the scraper portion 632 can scrape the dirt on the flexible annular belt portion away from the flexible annular belt portion, and further, the dirt enters the suction port 631.

[0225] The scraper portion 632 may be fixed to the housing module 650 , disposed adjacent to the suction port portion 631 , and located above the suction port portion 631 .

[0226] In the present disclosure, a support wheel 680 is also provided on the lower surface of the shell module. In the present disclosure, the number of the support wheels 680 can be two, and both support wheels 680 are located behind the dirty suction module. When the cleaning base moves forward or backward, the support wheels 680 rotate.
