Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a sewage tank, cleaning equipment and a cleaning system. Background Art

[0002] With the development of social economy and the improvement of people's living standards, cleaning equipment such as floor scrubbers and vacuum cleaners are increasingly used in people's daily lives due to their high cleaning efficiency, time-saving and labor-saving advantages.

[0003] Most models of floor scrubbers on the market require the inner cavity of the sewage tank to be pumped into a negative pressure state through a suction channel on the sewage tank cover, thereby sucking the sewage on the ground into the sewage tank through the sewage inlet channel.

[0004] However, when the cleaning equipment is moved, placed, or operated, sewage may surge and enter the suction channel, which may cause the motor to be damaged by water and the filter device to become wet and fail. Utility Model Content

[0005] In view of the above problems, the utility model provides a sewage tank, a cleaning device and a cleaning system, which can reduce the risk of sewage entering the suction channel, causing the filter component to become wet and fail, and the suction device to be damaged by water.

[0006] The utility model provides a sewage tank for cleaning equipment, comprising: a tank body, the tank body having a accommodating cavity with an opening at one end, the tank body also having a sewage inlet channel extending along the height direction of the tank body, the sewage inlet channel having a connecting port connected to the accommodating cavity; a tank cover assembly, the tank cover assembly is arranged at the opening of the tank body, the tank cover assembly defines a suction channel connected to the accommodating cavity; a water retaining assembly, comprising a water retaining frame and a water retaining block, the water retaining frame at least partially surrounding the circumference of the sewage inlet channel, the suction channel and the sewage inlet channel being separated by the water retaining frame, the water retaining block being arranged on a side of the water retaining frame facing away from the sewage inlet channel, and the water retaining block being constructed to prevent sewage in the accommodating cavity from flowing toward the suction channel when the cleaning equipment is moving or lying flat.

[0007] According to the sewage tank of the utility model, the water retaining frame can block most of the water vapor from flowing directly to the suction channel, and the water retaining block can inhibit the sewage from flowing to the suction channel due to the surge phenomenon. The water retaining frame and the water retaining block cooperate with each other to reduce the probability of the filter component being wetted and failing, and the probability of the suction device being damaged by water, thereby improving the reliability of the cleaning equipment and improving the user experience.

[0008] In some embodiments, the water retaining block is disposed at a height lower than a height of the connecting port, and the height of the water retaining block is not lower than a maximum allowable water level of the sewage tank.

[0009] In this way, when a surge occurs, it can be ensured that the water retaining block can prevent the water on the lower side of the water retaining block from surging to the upper side of the water retaining block, thereby ensuring the water retaining effect.

[0010] In some embodiments, the water retaining block is arranged at a height of 1 / 2-4 / 5 of the height of the sewage inlet channel.

[0011] In this way, on the one hand, the effectiveness of the water retaining effect of the water retaining block is guaranteed, and on the other hand, the sewage tank is guaranteed to have sufficient sewage capacity.

[0012] In some embodiments, the suction channel and the water retaining block are located on the same side of the water retaining frame.

[0013] In this way, the water retaining block can better prevent sewage from directly flowing into the suction channel.

[0014] In some embodiments, the shape of the water retaining block is adapted to the shape of the accommodating cavity, and the water retaining block divides the accommodating cavity into a first sub-chamber and a second sub-chamber, the first sub-chamber being located on the side of the water retaining block facing the box cover assembly, and at least a portion of the second sub-chamber being located on the side of the water retaining block facing away from the box cover assembly.

[0015] In this way, the sewage can be in the second sub-chamber after entering the accommodating chamber. The first sub-chamber is provided to facilitate the air circulation in the sewage tank on the one hand, and on the other hand, the second sub-chamber can serve as a buffer space between the suction channel and the water retaining block. Even if part of the sewage reaches the upper side of the water retaining block due to surges, it can be buffered by the second sub-chamber and avoid entering the suction channel.

[0016] In some embodiments, the water retaining block is provided with a through hole connecting the first sub-chamber and the second sub-chamber; and / or, a gap connecting the first sub-chamber and the second sub-chamber is defined between the water retaining block and the inner wall of the box body.

[0017] In this way, when the cleaning equipment is working, the air in the second sub-chamber can enter the first sub-chamber through the perforation, and finally be drawn into the suction channel, so that the sewage can enter the second sub-chamber from the sewage inlet channel; in addition, when a surge occurs, the perforation can reduce the impact of the sewage on the water retaining block; or, the air in the second sub-chamber can enter the first sub-chamber through the gap, and finally be drawn into the suction channel, so that the sewage can enter the second sub-chamber from the sewage inlet channel.

[0018] In some embodiments, the first end of the water retaining frame is connected to the box cover assembly, the second end of the water retaining frame extends to a side of the communication port away from the box cover assembly in the height direction, and the water retaining block is arranged adjacent to the second end.

[0019] In this way, a sufficient distance can be ensured between the water retaining block and the suction channel. In this way, when sewage surges, even if a small amount of sewage tumbles to the upper side of the water retaining block, it can also be avoided to the greatest extent that the sewage enters the suction channel and wets the filter assembly.

[0020] In some embodiments, the water retaining block and the water retaining frame are detachably connected; or, the water retaining block and the water retaining frame are integrally formed.

[0021] In this way, when the water retaining block and the water retaining frame are detachably connected, after the sewage tank has been used for a period of time, it is convenient for the user to separate the water retaining frame and the water retaining block and clean them separately, thereby reducing the growth of bacteria on the water retaining assembly. When the water retaining block and the water retaining frame are integrally formed, the installation stability of the water retaining block on the water retaining frame is higher. When sewage surges, the water retaining block can withstand greater impact to better buffer and suppress the surge.

[0022] In some embodiments, the water retaining frame and the side wall of the tank body jointly define an enclosed space, the projection of the sewage inlet channel on a reference plane is located within the projection of the enclosed space on the reference plane, and the reference plane is perpendicular to the height direction of the sewage tank.

[0023] In this way, the water retaining frame can better prevent water vapor from being sucked into the suction channel, thereby preventing the filter component from getting wet and the risk of water damage to the suction device. In addition, there is a gap between the outer wall of the sewage inlet channel and the inner wall of the enclosed space, which facilitates the sewage to enter the accommodating cavity from the sewage inlet channel.

[0024] In some embodiments, the water retaining frame is provided with an air outlet, and in the height direction of the sewage tank, the air outlet is located between the connecting port and the water retaining block.

[0025] By arranging the air passage, it is easier to form a negative pressure in the sewage inlet channel when the suction device sucks air through the suction device, so as to ensure the suction force for the sewage.

[0026] In some embodiments, the sewage tank further comprises: a water level detection device, wherein the water level detection device is disposed on at least one of the water retaining frame and the water retaining block.

[0027] In this way, the water retaining frame and the water retaining block can be used to provide an installation platform for the water level detection device, eliminating the need to separately configure an installation structure for the water level detection device.

[0028] In some embodiments, the sewage tank further includes: an alarm device, wherein the alarm device is configured to issue an alarm when the water level detection device detects that the water level in the sewage tank reaches a preset water level.

[0029] In this way, the alarm device can remind the user to pour out the sewage, further improving the user experience.

[0030] In some embodiments, the alarm device and the water level detection device are an integrated structure.

[0031] In this way, the integration is higher, the occupied space is less, and the effective volume of the sewage tank can be increased.

[0032] The second aspect of the utility model provides a cleaning device, comprising: a body; a cleaning component, used to clean a surface to be cleaned; and the sewage tank described in the first aspect of the utility model, wherein the sewage tank is arranged on the body and is constructed to receive sewage absorbed by the cleaning component.

[0033] The cleaning device of the utility model, by providing the above-mentioned sewage tank, can reduce the probability of the filter component being wetted and failing, and the probability of the suction device being damaged by water, thereby improving the reliability of the cleaning device and being conducive to improving the user experience.

[0034] The third aspect of the utility model provides a cleaning system, comprising: the cleaning device described in the second aspect of the utility model; and a cleaning base station, wherein the cleaning base station is at least configured to clean the cleaning device.

[0035] According to the cleaning system of the present invention, by providing the above-mentioned cleaning equipment, the reliability of the system can be improved, which is beneficial to improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0048] With the development of social economy and the improvement of people's living standards, cleaning equipment such as floor scrubbers and vacuum cleaners are increasingly used in people's daily lives due to their high cleaning efficiency, time-saving and labor-saving advantages. Most models of floor scrubbers on the market need to pump the inner cavity of the sewage tank into a negative pressure state through the suction channel on the sewage tank, and then suck the sewage on the ground into the sewage tank. However, when the cleaning equipment is working, the sewage may surge due to operations such as moving and placing, causing the sewage to enter the suction channel, and may cause water damage to the motor, wetting and failure of the filter device, and other problems.

[0049] In view of this, the utility model provides a sewage tank, cleaning equipment and cleaning system, wherein the water retaining frame can block most of the water vapor from flowing directly to the suction channel, and the water retaining block can, to a certain extent, suppress the sewage in the sewage tank from flowing to the suction channel due to the surge phenomenon. The water retaining frame and the water retaining block cooperate with each other to reduce the probability of the filter component being wetted and failing, and the probability of the suction device being damaged by water, thereby improving the reliability of the cleaning equipment and improving the user experience.

[0050] Combine the following Figure 1-Figure 3 The sewage tank 100 according to the first embodiment of the utility model is described.

[0051] The sewage tank 100 of this embodiment can be used for cleaning equipment, and the cleaning equipment can be a floor scrubber, a cleaning robot, a vacuum cleaner with a mopping function, etc. The cleaning equipment can be a household cleaning equipment or an industrial cleaning equipment, and this application does not impose any restrictions on this.

[0052] The cleaning device may include a body and a cleaning component. The body may be used to accommodate a sewage tank 100, which may be detachably mounted on the body. The body may also provide an installation platform and support for other components of the cleaning device. The cleaning component may be disposed at the bottom of the body. The cleaning component may move along a surface to be cleaned and clean the surface to be cleaned. For example, the cleaning component may include a roller brush, a side brush, etc. The side brush may gather dirt around the cleaning component to the center of the cleaning component, and the roller brush may suck in dirt, sewage, etc.

[0053] refer to Figure 1 The sewage tank 100 may include: a tank body 1, a tank cover assembly 2 and a water retaining assembly 3.

[0054] The box body 1 may define a receiving cavity 11 with an opening at one end, and the opening constitutes a sewage outlet. For example, the top of the box body 1 is open to form a sewage outlet. The receiving cavity 11 can be used to store sewage and dirt sucked in by the cleaning equipment during operation. The box body 1 may be cylindrical, square, or irregular in shape, and the shape of the box body 1 is adapted to the shape of the space on the machine body for accommodating the box body 1.

[0055] The box body 1 also has a sewage inlet channel 12, which extends in the height direction of the box body 1, and has a communication port 121 communicating with the accommodating chamber 11. For example, a channel partition is provided in the accommodating chamber 11, and the channel partition is in a cylindrical shape with both ends open, and the channel partition extends in the height direction of the box body 1 and defines the sewage inlet channel 12, and the communication port 121 is located at the top of the channel partition.

[0056] The box cover assembly 2 is arranged at the opening of the box body 1 to seal the sewage outlet. When the sewage in the box body 1 reaches a set capacity or when sewage needs to be dumped, the box cover assembly 2 can be removed from the box body 1 to dump the sewage from the sewage outlet. The box cover assembly 2 defines a suction channel 211, which is connected to the accommodating chamber 11. For example, the box cover assembly 2 may include a box cover 21, and the suction channel 211 is arranged on the box cover 21.

[0057] In this way, when the cleaning equipment is working, the suction device on the body, such as a suction motor, can suck the accommodating chamber 11 through the suction channel 211, so that the accommodating chamber 11 is in a negative pressure state, so as to facilitate the sewage and dirt on the surface to be cleaned to be sucked from the cleaning component through the sewage inlet channel 12 into the sewage tank 100. The surface to be cleaned can be the ground, the table, etc.

[0058] It is understandable that the sewage tank 100 may also include a filter assembly 5, which is arranged in the suction channel 211. The filter assembly 5 can prevent the sewage droplets and dirt in the sewage tank 100 from reaching the suction device through the suction channel 211, causing water ingress and damage to the suction device. In addition, the filter assembly 5 is detachably matched with the box cover assembly 2, so that after the filter assembly 5 has worked for a period of time, the filter assembly 5 can be disassembled for cleaning or replacement. Optionally, the filter assembly 5 may include a mounting frame 51 and a filter element 52. Specifically, the mounting frame 51 can be detachably matched with the box cover assembly 2 and provide better support for the filter element 52. The filter element 52 is arranged on the mounting frame 51 and is in the suction channel 211. The filter element 52 may be a HEPA, a filter screen, etc.

[0059] The water retaining assembly 3 may include a water retaining frame 31 and a water retaining block 32. The water retaining frame 31 may be connected to the box body 1, or may be connected to the box cover assembly 2, or may be connected to both the box body 1 and the box cover assembly 2. The water retaining frame 31 is at least partially arranged around the circumference of the sewage inlet channel 12, and the suction channel 211 and the sewage inlet channel 12 are separated by the water retaining frame 31. In this way, when the sewage inlet channel 12 enters the accommodating chamber 11, the water retaining frame 31 can block part of the water vapor from flowing to the suction channel 211, thereby reducing the probability of the filter assembly 5 being wetted and the suction device being damaged by water inflow.

[0060] The water retaining block 32 is arranged on the side of the water retaining frame 31 facing away from the sewage inlet channel 12. The water retaining block 32 is configured to prevent the sewage in the accommodating chamber 11 from surging toward the suction channel 211 when the cleaning device is moving or lying flat. In other words, the water retaining block 32 can suppress the sewage in the sewage tank 100 from surging toward the suction channel 211 due to the surge phenomenon, so that a large amount of sewage can be prevented from reaching the suction device through the suction channel 211, causing the filter assembly 5 to become wet and ineffective, and the suction device to be damaged by water ingress.

[0061] According to the sewage tank 100 of the embodiment of the utility model, the water retaining frame 31 can block most of the water vapor from flowing directly to the suction channel 211, and the water retaining block 32 can, to a certain extent, suppress the sewage in the sewage tank 100 from flowing to the suction channel 211 due to the surge phenomenon. The water retaining frame 31 and the water retaining block 32 cooperate with each other, which can reduce the probability of the filter assembly 5 being wetted and ineffective, and the probability of the suction device being damaged by water ingress, thereby improving the reliability of the cleaning equipment and improving the user experience.

[0062] refer to Figure 1The height of the water retaining block 32 is lower than the height of the connecting port 121, and the height of the water retaining block 32 is not lower than the maximum allowable water level of the sewage tank 100. It can be understood that the highest liquid level in the sewage tank 100, i.e., the maximum allowable water level, will not exceed the height of the connecting port 121. Therefore, the height of the water retaining block 32 of this embodiment is between the connecting port 121 and the maximum allowable water level. When a surge occurs, it can be ensured that the water retaining block 32 can prevent the water on the lower side of the water retaining block 32 from tumbling to the upper side of the water retaining block 32, thereby ensuring the water retaining effect.

[0063] In some embodiments, the height of the water retaining block 32 is 1 / 2-4 / 5 of the height of the sewage inlet channel 12. For example, the height of the water retaining block 32 is 1 / 2, 2 / 3, 3 / 4 or 4 / 5 of the height of the sewage inlet channel 12. Of course, the utility model does not limit this. The height of the water retaining block 32 can be reasonably selected within the above range. In this way, on the one hand, the effectiveness of the water retaining effect of the water retaining block 32 is guaranteed, and on the other hand, the sewage tank 100 is guaranteed to have sufficient sewage capacity.

[0064] In some embodiments, reference Figure 1 , the suction channel 211 and the water retaining block 32 are located on the same side of the water retaining frame 31. In this way, the water retaining block 32 can better block the sewage from directly rushing to the suction channel 211.

[0065] In some embodiments, reference Figure 1 The shape of the water retaining block 32 is adapted to the shape of the accommodating chamber 11. The water retaining block 32 divides the accommodating chamber 11 into a first sub-chamber 111 and a second sub-chamber 112. The first sub-chamber 111 is located on the side of the water retaining block 32 facing the box cover assembly 2, and at least a portion of the second sub-chamber 112 is located on the side of the water retaining block 32 facing away from the box cover assembly 2.

[0066] In this way, the sewage can be located in the second sub-chamber 112 after entering the accommodating chamber 11. The first sub-chamber 111 is provided to facilitate the air circulation in the sewage tank 100 on the one hand, and on the other hand, the second sub-chamber 112 can serve as a buffer space between the suction channel 211 and the water retaining block 32. Even if part of the sewage reaches the upper side of the water retaining block 32 due to surges, it can be buffered by the second sub-chamber 112 and avoid entering the suction channel 211.

[0067] In some possible embodiments, the water retaining block 32 may be provided with a perforation (not shown in the figure), the perforation passes through the water retaining block 32 along the thickness direction of the water retaining block 32, the perforation may connect the first sub-chamber 111 and the second sub-chamber 112, the perforation may be a circular hole, a square hole or any other shape, and in the thickness direction of the water retaining block 32, the cross-sectional area of ​​each perforation may be consistent, or the cross-sectional area of ​​the perforation may gradually increase or decrease. In this way, when the cleaning device is working, the air in the second sub-chamber 112 may enter the first sub-chamber 111 through the perforation, and finally be sucked into the suction channel 211, so that the sewage enters the second sub-chamber 112 from the sewage inlet channel 12; in addition, when a surge occurs, the provision of the perforation can reduce the impact of the sewage on the water retaining block 32.

[0068] In some embodiments, reference Figure 1 There is a gap between the water retaining block 32 and the inner wall of the box body 1, which connects the first sub-chamber 111 and the second sub-chamber 112. In this way, when the cleaning device is working, the air in the second sub-chamber 112 can enter the first sub-chamber 111 through the gap, and finally be sucked into the suction channel 211, so that the sewage enters the second sub-chamber 112 from the sewage inlet channel 12.

[0069] Optionally, perforations may be provided only on the water retaining block 32; or, a gap may be defined only between the water retaining block 32 and the inner wall of the box body 1; or, perforations and gaps may be provided at the same time to ensure the air flow efficiency between the first sub-chamber 111 and the second sub-chamber 112.

[0070] In some embodiments, in combination Figure 1 and Figure 3 The first end of the water retaining frame 31 is connected to the box cover assembly 2, and the second end of the water retaining frame 31 extends to a side of the connecting port 121 that is away from the box cover assembly 2 in the height direction, such as the lower side of the connecting port 121, and the water retaining block 32 is arranged adjacent to the second end. In this way, it can be ensured that there is a sufficient distance between the water retaining block 32 and the suction channel 211. In this way, when sewage surges, even if a small amount of sewage tumbles to the upper side of the water retaining block 32, it can be avoided to the greatest extent that the sewage enters the suction channel 211 and wets the filter assembly 5.

[0071] In some embodiments, reference Figure 2The water retaining block 32 is detachably connected to the water retaining frame 31. For example, a fixing portion may be provided on the water retaining frame 31, and a connecting portion may be provided on the water retaining block 32. The fixing portion may be a structure such as a slot or a socket, and the connecting portion may be a convex structure or a plug column adapted to the fixing portion, so that the water retaining block 32 can be detachably mounted on the water retaining frame 31. In this way, the assembly method between the water retaining block 32 and the water retaining frame 31 is relatively simple and easy to assemble. After the sewage tank 100 has been used for a period of time, it is convenient for the user to separate the water retaining frame 31 and the water retaining block 32 and clean them separately, thereby reducing the growth of bacteria on the water retaining assembly 3.

[0072] Of course, in other alternative implementations, the water retaining block 32 and the water retaining frame 31 can be integrally formed. In this way, the installation stability of the water retaining block 32 on the water retaining frame 31 is higher. When a sewage surge occurs, the water retaining block 32 can withstand a greater impact to better buffer and suppress the surge.

[0073] In some embodiments, reference Figure 1 The water retaining frame 31 and the side wall of the box body 1 jointly define an enclosed space, and the projection of the sewage inlet channel 12 on the reference plane is located within the projection of the enclosed space on the reference plane, and the reference plane is perpendicular to the height direction of the sewage tank 100. In this way, the water retaining frame 31 can better prevent water vapor from being sucked into the suction channel 211, thereby preventing the filter assembly 5 from being wetted and the risk of the suction device being damaged by water ingress, and there is a gap between the outer wall of the sewage inlet channel 12 and the inner wall of the enclosed space, which facilitates the sewage to enter the accommodating chamber 11 from the sewage inlet channel 12.

[0074] In some embodiments, reference Figure 2 The water retaining frame 31 is provided with an air port 311, and in the height direction of the sewage tank 100, the air port 311 is located between the connecting port 121 and the water retaining block 32. By providing the air port 311, when the suction device sucks air through the suction channel 211, it is easier to form a negative pressure in the sewage inlet channel 12, so as to ensure the suction force for the sewage on the surface to be cleaned.

[0075] Optionally, only one air outlet 311 may be provided, and the area of ​​the air outlet 311 may be relatively large; or, a plurality of air outlets 311 with smaller circulation areas may be provided to ensure air circulation on both sides of the enclosed space.

[0076] In some embodiments, in combination Figure 2 and Figure 3The sewage tank 100 may further include: a water level detection device 4, which is disposed on any one of the water retaining frame 31 and the water retaining block 32. For example, the water level detection device 4 may be disposed only on the water retaining frame 31 or only on the water retaining block 32, or a part of the water level detection device 4 may be disposed on the water retaining frame 31 and another part of the water retaining block 32. In this way, the water retaining frame 31 and the water retaining block 32 may be used to provide an installation platform for the water level detection device 4, eliminating the need to configure a separate installation structure for the water level detection device 4.

[0077] Optionally, combined Figure 2 The water level detection device 4 includes a first detection terminal 41 and a second detection terminal 42. When the sewage in the sewage tank 100 reaches the maximum allowable water level, the first detection terminal 41 and the second detection terminal 42 are connected through the sewage, and it can be judged that the sewage tank 100 is full of sewage, and the user can be notified to pour out the sewage or return the cleaning equipment to the cleaning base station for self-cleaning.

[0078] Furthermore, combined with Figure 2 and Figure 3 The water level detection device 4 is arranged on the water retaining frame 31, and the water level detection device 4 is located on the side of the water retaining block 32 away from the tank cover assembly 2. Since the height of the water level detection device 4 corresponds to the maximum allowable water level of the sewage tank 100, the water retaining block 32 is higher than the maximum allowable water level. In this way, there can be a certain height difference between the water retaining block 32 and the water surface of the sewage. The space corresponding to the height difference can be used to buffer the surging sewage and reduce the potential energy of the sewage on the water retaining block 32, so that the water retaining block 32 can better block the surge.

[0079] In some embodiments, the sewage tank 100 may further include an alarm device. The alarm device may be an audible and visual alarm device, a video alarm device, and an alarm image may be displayed on the display interface of the host of the cleaning device. The alarm device is configured to sound an alarm when the water level detection device 4 detects that the water level in the sewage tank 100 reaches a preset water level, so as to remind the user to pour out the sewage, thereby further improving the user experience.

[0080] In some embodiments, the alarm device and the water level detection device 4 are integrated into one structure, so that the integration is higher, the occupied space is less, and the effective volume of the sewage tank 100 can be increased.

[0081] The cleaning device of the second embodiment of the utility model is described below.

[0082] The cleaning device of this embodiment can be a floor scrubber, a cleaning robot, a vacuum cleaner with a mopping function, etc. The cleaning device can be a household cleaning device or an industrial cleaning device, and this application does not limit this. The cleaning device can include: a body, a cleaning component, and the sewage tank 100 in the above embodiment.

[0083] Specifically, the fuselage can be used to accommodate the sewage tank 100, and the sewage tank 100 is detachably arranged on the fuselage. The fuselage can also provide a mounting platform and support for other components of the cleaning device, and provide an operating handle 213 and the like for the user.
