Description

Cleaning equipment

Technical Field

The invention relates to the technical field of cleaning, in particular to cleaning equipment.

Background

The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

In recent years, with the continuous improvement of living standard of people, automobiles have been moved into thousands of households to become daily tools for riding instead of walk in families, and therefore the cleaning requirements of automobiles are increased gradually. The common car washing methods at present are as follows: manual car washing, automatic computer car washing, household car washer car washing and steam car washing in the car washing house. Both manual car washing and automatic computer car washing in a car washing house face the problems that a car washing place is far away from the place where a car owner lives, needs to wait in a queue and is high in water consumption, and therefore water resources, time and car washing cost are wasted. The household car washer is provided with a portable water gun using a vehicle-mounted 12V power supply, at least one barrel of water is needed, the lifting of the barrel of water upstairs and downstairs is inconvenient to carry, a lot of troubles are added to the car washer every time for a user, troubles are caused, and the household car washer is not suitable for urban crowds. The water-spraying type household car washer adopting manual inflation as a power source has the defects of time and labor waste and inconvenient use. The water-saving steam car washing has high equipment price, large volume, inconvenient carrying and large energy requirement of a heat source, and brings potential safety hazards due to the adoption of gas and high-power electric heat at present.

Due to the various inconveniences of the above-mentioned car washing, portable pressure cleaning devices have come into use, which generally wash the surface of an object by generating a high-pressure water flow, for example, by means of a plunger pump. Compared with the cleaning mode, although the water consumption of the portable pressure cleaning equipment is reduced to a certain extent, and a large amount of time is saved, the requirements of the current portable pressure cleaning equipment on the water quantity and the water outlet pressure are still high, and the portable pressure cleaning equipment cannot be used quickly when cleaning automobiles, kitchens and walls. For example, automobiles require multi-angle, multi-wash surface washing, and the portable pressure cleaning apparatus is still unable to quickly access each surface being washed; meanwhile, the car roof or the cleaning surface which is forbidden to be cleaned by using pressure water flow exists, and at the moment, a user needs to use cleaning cloth to clean the car roof in a matched mode. For another example, when in some washing scenes, the portable pressure cleaning device needs to be held and controlled to be washed at multiple angles, which also means that the user needs to overcome the recoil force of the pressure water flow and the gravity action of the portable pressure cleaning device, and the operation experience is not good. In addition, after the pressure cleaning device is used for stripping off the dirt, the dirt flows downwards along with the water flow, so that the surface which is not dirty or does not need to be cleaned is polluted, and secondary cleaning is needed. Meanwhile, the place for washing the car by the user in the city is limited, and the cleaning of the sewage after car washing is also a difficult problem for the user.

It should be noted that the above background description is only for the sake of clarity and complete description of the technical solutions of the present invention and for the understanding of those skilled in the art. Such solutions are not considered to be known to the person skilled in the art merely because they have been set forth in the background section of the invention.

As described in the background art, the portable cleaning device and the ground-washing cleaning device in the prior art cannot meet the dual requirements of multi-angle cleaning and rapid sewage recovery. Therefore, a cleaning device is proposed to address this need.

As shown in fig. 1 to 10, the present invention provides a cleaning apparatus including a cleaning head 10, a hand-held frame 20, and a sewage extracting mechanism 30, wherein: the handheld frame 20 is provided with a handheld end for an operator to hold the cleaning equipment; the cleaning head 10 is arranged at one side of the handheld frame 20, and the cleaning head 10 comprises a working brush 11, a water storage tank 12 arranged at one side of the working brush 11, and a sewage suction port 124 for recovering sewage 70 in the water storage tank 12; the sewage pumping mechanism 30 comprises a pumping channel 301 and a pumping power unit, wherein the pumping channel 301 is communicated with the water storage tank 12; the sewage suction port 124 includes a first sewage suction port 1241 and a second sewage suction port 1242, the sewage suction mechanism 30 can collect the sewage 70 received in the water storage tank 12 through the first sewage suction port 1241 and/or the second sewage suction port 1242, and the first sewage suction port 1241 and the second sewage suction port 1242 are respectively located at both ends of the water storage tank 12 in the longitudinal direction.

In the cleaning apparatus of the present invention, the hand-held rack 20 is disposed along the longitudinal direction Y to be apart from the cleaning head 10 in the longitudinal direction Y, which facilitates a hand-held operation, so that the cleaning head 10 can clean a surface to be cleaned, such as a body surface of the automobile 100. Of course, the surface to be cleaned in the present invention is not limited to the surface of the vehicle body, and may be, for example, a wall surface or the like.

In the present invention, the "multiple cleaning surfaces" may be understood as the cleaning head 10 of the cleaning apparatus being capable of cleaning horizontal surfaces, sloping surfaces, vertical surfaces, etc. Under the multi-working condition of realizing the cleaning of different cleaning surfaces, the cleaning head 10 of the portable cleaning device can present a plurality of different using postures as shown in fig. 2, 4 and 6. For example, referring to fig. 10, if a horizontal plane (ground) is used as a reference plane, the angle of the length direction X of the cleaning head 10 relative to the horizontal plane may be any angle, that is, the height of the two ends of the length direction X of the cleaning head 10 in the vertical direction Z (i.e., the gravity direction) is different due to different slopes of different cleaning surfaces.

"Multi-angular" is to be understood as meaning that the portable cleaning apparatus has a plurality of working positions in which the user holds the cleaning apparatus at a distance from the floor surface and the cleaning head 10 at a distance from the floor surface in the actual cleaning operation. For example, the user can wash the entire cleaner head 10 in the vertical direction Z in an upper position (as shown in fig. 9), a lower position (as shown in fig. 2 and 3), or a position in which the cleaner head 10 is substantially at the same height as the holder 20 (as shown in fig. 6) with respect to the holder 20 while holding the holder 20, and the above three modes of use can be used in combination.

As shown in fig. 9, the cleaning head 10 as a whole can be raised in the vertical direction Z with respect to the holder 20, while one end of the length direction X of the cleaning head 10 (e.g., the end near the inner side of the drawing in fig. 9) is raised in the vertical direction Z with respect to the other end of the cleaning head 10 so that the length direction X of the cleaning head 10 forms an angle with the horizontal plane.

When the cleaning equipment is used specifically, the surface to be cleaned by the cleaning head 10 has a slope, and two ends in the length direction X of the cleaning head 10 have a high end and a low end, namely two ends in the length direction X of the cleaning head 10 have different heights in the vertical direction Z, under the states, sewage 70 stored in the water storage tank 12 can be sucked into the corresponding suction channel 301 through the suction power unit, and a sewage suction port positioned at the lower part (the end at the lower position of the water storage tank) of the water storage tank 12 along the gravity direction can be always communicated with the suction power unit, so that the cleaning equipment is effectively ensured to carry out effective sewage suction operation based on different actual conditions of the surface to be cleaned, and the universality and the practicability of the use scene of the cleaning equipment are improved.

Specifically, as shown in fig. 10, the cleaning head 10 includes a working brush 11, and a water storage tank 12 provided at one side of the working brush 11, the working brush 11 being used to clean a surface to be cleaned, and the water storage tank 12 being used to collect sewage 70 after cleaning, that is, the sewage 70 may be stored in the water storage tank 12. Referring to fig. 1 and 11, the working brush 11 includes a frame 111, a roller 113 having bristles 112 and mounted on the frame 111, and a motor 114, the motor 114 is in transmission connection with the roller 113 to drive the bristles 112 to rotate, and the water storage tank 12 and the handheld frame 20 are both connected to the frame 111. The water storage tank 12 and the framework 111 can be integrally arranged or detachably connected. The working brush 11 is specifically configured as a roll brush.

As shown in fig. 1, a battery pack 40 for supplying power to the motor 114 is also provided on the handheld stand 20. A battery pack 40 is removably arranged at the end of the hand held frame 20 remote from the cleaning head 10. The battery pack 40 may be a lithium battery, but is not limited thereto. The above-mentioned longitudinal direction Y is disposed at an angle to the axial direction of the working brush 11 (i.e., the axial direction of the roller body 113), specifically, perpendicular to each other. The water storage tank 12 is provided along the axial direction of the working brush 11, and has a length matching the axial length of the working brush 11, so that the sewage 70 at various positions in the axial direction of the working brush 11 can be collected. In this embodiment, the axial direction of the working brush 11 is the longitudinal direction X of the cleaning head 10. When the position of the working brush 11 with respect to the holder 20 in the vertical direction Z or the angle with respect to the horizontal plane changes, it is considered that the working angle of the cleaning head 10 changes.

The waste water 70 in this embodiment refers to waste liquid after cleaning, and correspondingly, fresh liquid before cleaning is referred to as clean water, wherein the clean water includes clean water, clean water containing cleaning liquid, and the like, and the specific type is not particularly limited. When the water purifier is used specifically, the working brush 11 is soaked with purified water, and the purified water can be obtained by soaking the working brush 11 in a purified water pool, flushing the working brush under the purified water and independently spraying the purified water; alternatively, as shown in fig. 1, a water supply system 60 may be provided on the hand-held frame 20, and the water supply system 60 may spray clean water onto the work brush 11 in real time. The working brush 11 is brought into contact with a surface to be cleaned, such as the surface of the automobile 100, and the surface of the automobile body is cleaned by pressing friction with the surface of the automobile body, and the sewage 70 flows into the reservoir 12. When the water supply system 60 is provided on the hand-held rack 20, the cleaning apparatus is configured as an automatic cleaning apparatus, which can perform automatic cleaning without being limited by the location of the water source, for example, a user does not have to perform cleaning work near the water source.

In order to rapidly recycle and store the contaminated water 70 from the brush bristles 112 in the water storage tank 12, as shown in fig. 11 and 12, a dirt removing unit, specifically, a wiper strip 13 extending toward the roller body 113 is further mounted on the frame 111, the wiper strip 13 interferes with the brush bristles 112, and the wiper strip 13 is located on a rotation path of the brush bristles 112. The sump 12 has a dirt inlet 123, and the dirt inlet 123 is located at one side of the wiper strip 13 and opens toward the interference of the wiper strip 13 and the brush bristles 112. When the angle of the cleaning apparatus is as shown in fig. 1, the dirt inlet 123 of the reservoir 12 is located below the wiper strip 13. When the cleaning apparatus is used, as shown in fig. 11, the roller body 113 rotates counterclockwise, the end of the wiper strip 13 contacts the brush staples 112, and the waste water 70 on the brush staples 112 is continuously scraped into the water storage tank 12. Through setting up the wiping strip 13, improved sewage 70 recovery efficiency, can adapt to the automatic washing of high requirement.

As shown in connection with fig. 1, the wiper strip 13 is integrated in a sealing cap 14. The sealing cover 14 is detachably mounted on the frame 111. After the sealing cover 14 is installed, the sealing cover 14 just covers the water storage tank 12, so that the upper part of the water storage tank 12 is communicated with the outside only through the sewage inlet 123. Meanwhile, the wiper strip 13 extends toward the roller body 113 and just interferes with the brush bristles 112, so that the contaminated water 70 on the brush bristles 112 can be wiped into the reservoir 12. By providing a removable sealing lid 14, the interior of the reservoir 12 can be conveniently cleaned.

As shown in fig. 1 and 10, the sewage extraction mechanism 30 is in communication with the storage tank 12 and is capable of transferring the sewage 70 from the storage tank 12 out of the storage tank 12 to accommodate the need for continuous cleaning operations.

In order to enable the sewage pumping mechanism 30 to quickly transfer the sewage 70, as shown in fig. 10 to 12, in an embodiment where the cleaning head 10 has the sewage suction ports provided in only one area, specifically, the number of the sewage suction ports in a single area may be one or a plurality of the sewage suction ports close together. The inner cavity volume of the sewage suction and storage tank 12 is gradually reduced from the sewage inlet 123 to the sewage suction port 124 of the storage tank 12.

In one possible embodiment, the inlet 123 is disposed at the upper portion of the water storage tank 12, the suction inlet 124 is disposed at the lower portion of the water storage tank 12 and is communicated with the outside, and the water storage tank 12 is large at the top, that is, the water storage tank 12 is funnel-shaped or cone-shaped. Accordingly, the sewage 70 can be converged toward the lower portion of the storage tank 12 after entering from the sewage inlet 123, so that the lower portion of the storage tank 12 can have a high level of the sewage 70, thereby facilitating the extraction of the sewage extraction mechanism 30. In the present invention, as shown in fig. 11, the upper portion of the sump 12 can be understood as: a portion of the reservoir 12 located above the center C in the depth direction of the reservoir 12; correspondingly, the lower part of the reservoir 12 can be understood as: the reservoir 12 is located below the center C of the reservoir 12 in the depth direction. Understandably, the lower the position of the soil suction port 124, the better.

As shown in fig. 11, the water storage tank 12 includes a bottom wall 121 and a side wall 122 connected to the bottom wall 121, the side wall 122 and the bottom wall 121 enclose an inner cavity of the water storage tank 12, the sewage inlet 123 is opened on the side wall 122, and the sewage suction port 124 is opened on the bottom wall 121 of the water storage tank 12. Since the storage tank 12 is formed in a funnel shape with a large upper portion and a small lower portion, the sewage 70 can be concentrated toward the bottom wall 121, thereby facilitating the extraction of the sewage extracting mechanism 30. Further, as shown in fig. 10, the suction port 124 may be opened on the side wall 122 near the bottom wall 121, which also facilitates the extraction of the contaminated water 70. It will be appreciated that the cleaning apparatus should be operable to change the angle of the cleaner head 10 while ensuring that the reservoir 12 is at least partially in a position to collect the soiled water 70. Specifically, the dirt inlet 123 of the reservoir 12 is located at least partially below the point where the wiper strip 13 interferes with the brush bristles 112.

In this embodiment, when the position of the cleaner head 10 relative to the holder 20 in the vertical direction is changed or the angle of the cleaner head 10 itself relative to the horizontal plane is changed, the water storage tank 12 is displaced relative to the cleaner head 10, and particularly, the water storage tank 12 can rotate relative to the cleaner head or the shape of the water storage tank 12 itself can be changed, so that the sewage 70 in the water storage tank 12 can flow to the lower part of the water storage tank 12 in the gravity direction, thereby facilitating the suction of the sewage 70 from the sewage suction port 124 located at the lower part of the water storage tank 12 in the gravity direction.

When both ends (refer to the a end and the B end in fig. 10) of the sump 12 are different in height in the vertical direction Z, rapid absorption of the sewage 70 can be facilitated. And, when both ends of the sump 12 are the same height in the vertical direction Z, it is also advantageous to rapidly absorb the sewage 70. And when the heights of the two ends of the water storage tank 12 change, the working angle of the cleaning equipment is reflected to change. Therefore, the cleaning equipment of the embodiment can meet the dual requirements of multi-angle cleaning and quick recovery of the sewage 70.

Further, as shown in fig. 10 and 11, the cross-sectional area of the interior cavity of the reservoir 12 decreases in a direction toward the hand held frame 20. I.e., in a direction that forms an acute angle with the longitudinal direction Y and approaches the hand holder 20, the cross-sectional area of the reservoir 12 is gradually reduced so that the reservoir 12 extends obliquely away from the working brush 11 and approaches the hand holder 20. Thus, when the cleaning head 10 is raised or substantially leveled in the vertical direction with respect to the hand holder 20, the dirty water 70 can be quickly collected toward the lower portion of the water storage tank 12, and the recovery of the dirty water 70 can be speeded up. And the water storage tank 12 extends obliquely, therefore, the water storage tank 12 is closer to the sewage extraction mechanism 30 on the handheld frame 20, and the sewage 70 flowing into the water storage tank 12 can be close to the sewage extraction mechanism 30, which is beneficial to shortening the suction path and quickening the recovery of the sewage 70.

In another possible embodiment, as shown in figure 12, the reservoir 12 may also be configured to include a portion that is capable of changing shape following changes in the angle of the cleaner head 10. Specifically, the water storage tank 12 includes a flexible water bag 101 capable of changing in shape according to the angle of the cleaning head 10, and the soil suction port 124 is provided at the bottom of the water bag 101. In which the change in shape of the water bag 101 as the angle of the cleaning head 10 is changed is illustrated by the dotted lines in figure 12. Specifically, when the angle of the cleaning head 10 is changed when the sump 12 stores therein the contaminated water 70, the shape of the sump 12 is changed by the gravity of the contaminated water 70, so that the sump 12 can always collect and store the contaminated water 70 quickly, allowing the cleaning head 10 to be washed in a greater range of angles.

In the present invention, the cleaning head 10 has the suction ports at both ends in the longitudinal direction of the water storage tank 30, that is, the suction ports are provided in different areas. Specifically, the suction ports include a first suction port 1241 and a second suction port 1242. Preferably, the number of the first and second soil suction ports 1241 and 1242 is one. Of course, the number of the first dirt suction port 1241 and the second dirt suction port 1242 may be plural. The first and second soil suction ports 1241 and 1242 are located at positions shifted from a center line of the length of the sump 12 toward both ends by a predetermined distance, and the predetermined distance is configured to be greater than or equal to 1/4 of the length of the sump 12. Preferably, if the first and second soil suction ports 1241 and 1242 are provided in plural, at least one soil suction port is located in the above-mentioned predetermined distance range at both ends of the water storage tank 30. The first and second soil suction ports 1241 and 1242 are provided symmetrically with respect to the center line. Wherein the centre line is understood to be located substantially in the middle of the length direction (X-direction) of the reservoir. The centre line is perpendicular to the axis of rotation of the working brush.

Further, in a possible embodiment of the suction port, as shown in fig. 35, the suction passage 301 includes a first inlet pipe 3011 and a second inlet pipe 3012, the first inlet pipe 3011 and the second inlet pipe 3012 each include an inlet end extending into the inner cavity of the water storage tank 12 for absorbing the sewage 70, and the first suction port 1241 and the second suction port 1242 are configured to be formed by the inlet ends of the first inlet pipe 3011 and the second inlet pipe 3012.

In another possible embodiment of the sewage suction port, the water storage tank 12 includes a housing enclosing to form a water storage cavity, the first sewage suction port 1241 and the second sewage suction port 1242 are configured as through holes penetrating at least a part of the housing and communicating with the cavity of the water storage tank 12, and the suction passage 301 is connected with the through holes to suck out the sewage 70.

In the present invention, the cleaning head 10 is provided with at least one of the following usage postures: one of the first and second soil suction ports 1241 and 1242 is configured to flow through the contaminated water 70 generated by the work brush 11; wherein the use gesture comprises: a first usage posture in which one end of the water storage tank 12 in the longitudinal direction is at a raised position with respect to the other end thereof in the direction of gravity, and a second usage posture in which the first dirt suction port 1241 and the second dirt suction port 1242 are on the same horizontal plane.

According to an embodiment of the present invention, as shown in fig. 13, the cleaning apparatus further includes a switching mechanism 50, the first soil suction port 1241 is located at one end of the storage tank 12 in the longitudinal direction, the second soil suction port 1242 is located at the other end of the storage tank 12 in the longitudinal direction, and when the cleaning apparatus is in a first usage posture in which the one end of the storage tank 12 in the longitudinal direction is in an elevated position with respect to the other end thereof in the gravity direction, the switching mechanism 50 is configured to close the passage between the first soil suction port 1241 and the suction power unit and open the passage between the second soil suction port 1242 and the suction power unit.

In one possible embodiment, the switching mechanism 50 includes a movable member 51 and a driving unit 52, and the driving unit 52 can drive or control the movable member 51 to move so as to close or open a passage between one of the first dirt suction port 1241 and the second dirt suction port 1242 and the suction power unit.

Specifically, referring to fig. 14 and 15, the movable member 51 includes a first movable member and a second movable member disposed in the water storage tank 12, the first movable member is configured to open or close the first sewage suction port 1241, and the second movable member is configured to open or close the second sewage suction port 1242. In this embodiment, the first movable member and the second movable member are both the baffle plates 511, and the two baffle plates 511 are disposed in the water storage tank 12 and are disposed in one-to-one correspondence with the first dirt suction port 1241 and the second dirt suction port 1242.

In the present embodiment, the driving unit 52 is a gravity sensing unit, which may be manually controlled or automatically operated according to the change of the angle of the cleaning head 10. The number of the driving units 52 is two, each driving unit 52 comprises an elastic member 521 and a gravity block 522 which are respectively connected with the movable member 51, and the elastic member 521 is configured to provide an elastic force which enables the movable member 51 to have a movement tendency of opening the dirt suction port; in a state that the gravity borne by the gravity block 522 is greater than the elastic force, the gravity block 522 can drive the baffle 511 (i.e. one of the first movable member and the second movable member) to move so as to open the corresponding dirt suction port; in a state where the gravity block 522 bears a gravity force smaller than the elastic force, the baffle 511 (i.e., one of the first movable member and the second movable member) closes the soil suction port by the elastic force. That is, the gravity sensing unit gives the baffle 511 a driving force to approach the soil suction port when the corresponding soil suction port is raised relative to the other soil suction port until the raised soil suction port is closed.

In the present embodiment, the elastic member 521 is configured to provide an elastic force for moving the baffle 511 away from the dirt suction port, and the gravity block 522 is subjected to a larger gravity force than the elastic force. As shown in fig. 14 and 15, the weight block 522 has a first position L1 distant from the soil suction port 124 and a second position L2 close to the soil suction port 124 in the axial direction of the work brush 11, the first position L1 being close to the other soil suction port 124. The gravity block 522 is switchable between the first position L1 and the second position L2 by gravity, and moves to a lower one of the first position L1 and the second position L2 in the vertical direction. Specifically, referring to fig. 14 in conjunction with fig. 13, in the vertical direction Z, the second position L2 is lower, and the gravity block 522 is in the second position L2; referring to fig. 15 in conjunction with fig. 13, when the cleaning head 10 is turned to lower the first position L1, the gravity block 522 moves to the first position L1 by gravity.

As shown in fig. 15, when the weight block 522 is in the first position L1, the gravity of the weight block 522 is transmitted to the baffle 511, and the gravity is greater than the elastic force, so that the baffle 511 closes the corresponding dirt suction port. As shown in fig. 14, when the weight block 522 is in the second position L2, the weight block 522 does not act on the flap 511, and the elastic force of the elastic member 521 causes the flap 511 to open the corresponding dirt suction port. Since the first position L1 is close to the other soil suction port, when the first position L1 of the gravity block 522 corresponding to a certain soil suction port is located below the second position L2 of the gravity block 522, it means that the soil suction port is located above the other soil suction port in the vertical direction. Therefore, as long as the first dirt suction port 1241 and the second dirt suction port 1242 have a height difference in the vertical direction Z, the gravity block 522 corresponding to the higher dirt suction port will move to the first position L1 thereof, so as to achieve the purpose of closing the higher dirt suction port; at the same time, the gravity block 522 corresponding to the lower suction port moves to the second position L2, the gravity of the gravity block 522 does not act on the baffle 511, and the baffle 511 opens the suction port by the elastic force. Specifically, as shown in fig. 13, the first soil suction port 1241 and the second soil suction port 1242 are arranged vertically, the upper first soil suction port 1241 is closed by the baffle 511, and the lower second soil suction port 1242 is opened.

In specific implementation, the gravity block 522 is disposed in the water storage tank 12, a pivot 524 is disposed in the water storage tank 12, the driving unit 52 further includes a flexible connecting member 523, a first end of the flexible connecting member 523 is connected to the gravity block 522, a second end of the flexible connecting member 523 bypasses from one side of the pivot 524 and is connected to one end of the movable member 51 close to the corresponding dirt suction port, and when the gravity of the gravity block 522 is greater than the elastic force, the flexible connecting member 523 is tensioned and supported on the pivot 524.

In this embodiment, the elastic member 521 is preferably a tension spring, which always gives the baffle 511 a tension force, so that the baffle 511 always has a tendency to move away from the dirt suction port 124. Thus, when the gravity block 522 moves to the first position L1, the gravity block 522 pulls the flexible connecting member 523, so that the baffle 511 moves in the direction opposite to the gravity direction of the gravity block 522, and finally the dirt suction port 124 is blocked.

Preferably, the fulcrum 524 is provided as a fixed pulley, which facilitates sliding of the flexible link 523 on the fulcrum 524. In addition, the gravity block 522 is preferably spherical and can be switched between the first position L1 and the second position L2 in a rolling manner.

In other embodiments, the gravity sensing unit may be configured as follows: the elastic member 521 is configured to always give a pushing force to the flapper 511 so that the flapper 511 always has a movement tendency to close the corresponding suction port. The gravity block 522 is capable of applying gravity to the baffle 511 to overcome the pushing force of the elastic member 521 to open the corresponding soil suction port as the position changes, or the gravity does not apply to the baffle 511 to cause the baffle 511 to block the corresponding soil suction port under the pushing force of the elastic member 521. Specifically, the gravity block 522 is still defined to have a first position L1 distant from the soil suction port and a second position L2 close to the soil suction port, the first position L1 being close to the other soil suction port. The gravity block 522 is switchable between the first position L1 and the second position L2 by gravity, and moves to a lower one of the first position L1 and the second position L2 in the vertical direction. In this embodiment, when the gravity block 522 moves to the second position L2, the gravity block 522 may press against the baffle 511, so as to press the baffle 511 onto the corresponding soil suction port, thereby blocking the soil suction port. Conversely, when the gravity block 522 is in the first position L1, away from the flapper 511, the gravity block 522 cannot press the flapper 511 toward the corresponding soil suction port, which is in an open state.

In the above embodiment, the driving unit 52 can automatically drive the movable member 51 to block the upper dirt suction port according to the angle change of the cleaning head 10, so that an air pressure difference is formed between the inside and the outside of the water storage tank 12, and the dirt suction port located below the water storage tank in the gravity direction can smoothly suck the sewage 70. In addition, in this embodiment, only one suction power unit may be provided, so as to save cost, and by providing the switching mechanism 50, the dirt suction port located below the water storage tank 12 in the direction of gravity is automatically opened, and the dirt suction port located above the water storage tank 12 in the direction of gravity is automatically closed, so that it is still ensured that the sewage 70 can be quickly sucked when the angle of the cleaning head 10 is changed.

In another possible embodiment of the switching mechanism 50, as shown in fig. 16, the driving unit 52 includes an angle sensor 525 and a control unit 526, the angle sensor 525 can detect the inclination angle of the cleaning device, and the control unit 526 can control the moving member 51 to move according to the monitoring result of the angle sensor 525 to close the passage between the first soil suction port 1241 at the end of the raised position of the storage tank 12 and the suction power unit and to open the passage between the second soil suction port 1242 and the suction power unit. In this embodiment, the angle sensor 525 may be preset to establish a horizontal reference and a corresponding relationship with the first and second soil suction ports 1241 and 1242, so that when the first and second soil suction ports 1241 and 1242 have a height difference in the vertical direction, it can be determined which position is higher and which position is lower.

Specifically, the suction channel 301 includes a three-way pipe 53, the three-way pipe 53 includes a first water pipe 531, a second water pipe 531 and at least one water outlet pipe 532, and the two water pipes 531 are respectively communicated with the water storage tank 12. The number of the first water conveying pipe 531 and the second water conveying pipe 531 may be one or more than one. In this embodiment, two water feeding pipes 531 are connected to the first inlet pipe 3011 of the suction passage and the second inlet pipe 3012 of the suction passage, respectively. Of course, in the embodiment of the three-way pipe, the first water duct 531 and the second water duct 531 of the three-way pipe may directly serve as the first inlet pipe and the second inlet pipe of the suction channel. The movable member 51 includes two valves, i.e., a first valve 54 and a second valve 55, which are installed in the two water pipes 531 in a one-to-one correspondence; the control component 526 can control any valve to block or open the corresponding water pipe 531 according to the detection result of the angle sensor 525.

In this embodiment, the angle sensor 525 detects the inclination angles of the first and second dirt suction ports 1241 and 1242, and the control component 526 controls the valve located lower in the vertical direction Z to be opened and the valve located upper to be closed according to the monitoring result of the angle sensor 525. Specifically, the angle sensor 525 and the control assembly 526 are both disposed on a motherboard and then mounted to the handheld stand 20 as shown in FIG. 1. Of course, in other embodiments, the angle sensor 525 may directly correspond to the first valve 54 and the second valve 55, directly detect whether the first valve 54 and the second valve 55 are raised or lowered relative to the horizontal reference, and then use the control component 526 to issue corresponding action commands. If the first valve 54 is located below, the suction port corresponding to the first valve 54 is also located below, and at this time, the first valve 54 is opened to close the second valve 55, so that the sewage 70 is collected downward, and the extraction by the sewage extraction mechanism 30 can be accelerated. Of course, the angle sensor 525 may be preset to establish a horizontal reference and corresponding relationship with the two valves.

Further, the control assembly 526 includes a controller and control circuitry, and the controller controls the movement of the first valve 54 and the second valve 55 via the control circuitry. The type of controller is not limited, and may be an embedded Digital Signal Processor (DSP), a Microprocessor (MPU), or the like. The two valves may be, but are not limited to, electrically operated ball valves.

In this embodiment, the two valves may be replaced with an element that can move relative to the water duct 531 to close or open the corresponding water duct 531. Specifically, the two water pipes 531 are respectively communicated with the first sewage suction port 1241 and the second sewage suction port 1242, the outlet pipe 532 is communicated with the sewage tank 32, and the control component 526 can control the movable member 51 to reciprocate to alternatively plug one of the two water pipes 531. For example, as shown in fig. 16, the movable member 51 is located at the left water duct 531 and blocks the water duct 531, and at this time, the right water duct 531 is in an open state. As shown by the dotted line in fig. 16, when the movable element 51 moves to the right, the movable element 51 blocks the right water duct 531, and the left water duct 531 is in an open state.

In addition, the movable member 51 may also be rotatably disposed inside the water duct 531, and the rotation plane of the movable member 51 is perpendicular to the axial direction of the water duct 531, so that the purpose of plugging or opening the water duct 531 can be achieved by rotating the movable member 51. It is understood that a movable member 51 is disposed in each of the two water feeding pipes 531. For example, the movable member 51 may be a valve body of a solenoid valve. The control component 526 controls the valve body of the corresponding electromagnetic valve to close the corresponding water conveying pipe 531 according to the monitoring result of the angle sensor 525.

In a variant embodiment, as shown in fig. 17, the difference from the embodiment shown in fig. 16 is that: the movable member 51 includes a valve body 512 of the solenoid valve, and the movable member 51 can reciprocate between the two water feeding pipes 531 to alternatively close one of the water feeding pipes 531, so that the cleaning device forms a pressure difference between the inside and the outside of the water storage tank 12, and the sewage 70 can be sucked from a sewage suction port which is lower in position in the vertical direction.

In yet another possible embodiment of the switching mechanism 50, the two ends of the water storage tank 12 are respectively provided with a first sewage suction port 1241 and a second sewage suction port 1242, the switching mechanism 50 is configured as a three-way valve 56, the three-way valve 56 comprises two valve inlets 562 respectively connected with the two water pipes 531, and a valve outlet 563 connected with the outlet pipe 532, the three-way valve 56 has an inner cavity 5611, and the two valve inlets 562 and the valve outlet 563 are respectively communicated with the inner cavity 5611; a movable member 564 is disposed within the internal cavity 5611, wherein the movable member 564 is configured to be movable toward the valve inlet 562 to close the first suction opening 1241 at one end of the raised position of the reservoir 12 from the suction power unit and open the second suction opening 1242 from the suction power unit.

Specifically, the three-way valve 56 has a valve body 561, the valve body 561 forms an inner cavity 5611, two valve inlets 562 are respectively communicated with a first sewage suction port 1241 and a second sewage suction port 1242 which are positioned at two ends of the water storage tank 12, the valve body 561 has an inner cavity 5611, and the two valve inlets 562 and the valve outlet 563 are respectively communicated with the inner cavity 5611; the inner cavity 5611 of the valve body 561 is provided with: the moving member 564 is used to block off the two valve inlets 562.

In this embodiment, the movable member 564 includes a first movable member 5641 and a second movable member 5642, which are respectively used for blocking the passage between the two valve inlets 562 and the two water pipes 531; at least one driving unit 565 interposed between the two first moving elements 5641 and the second moving element 5642; under the action of gravity, the driving unit 565 drives the movable members 564 to move, in a state where one of the movable members 564 blocks the corresponding valve inlet 562, the other movable member 564 is separated from the corresponding other valve inlet 562, and the valve outlet 563 is communicated with the other valve inlet 562.

Specifically, in one possible embodiment, as shown in fig. 18 to 21, there are two driving units 565 located between the first movable element 5641 and the second movable element 5642; in the condition where one of the movable members 564 blocks the corresponding valve inlet 562, the other movable member 564 is separated from the corresponding other valve inlet 562, and the valve outlet 563 is communicated with the other valve inlet 562.

In this embodiment, the movable member 564 may be a stainless steel ball, the driving unit 565 may also be a stainless steel ball, and the outer diameter of the driving unit 565 is larger than that of the movable member 564, so as to drive the movable member 564 to move.

When the cleaning device works in a clockwise inclined state, the internal state of the three-way valve 56 is as shown in fig. 19, when the sewage pumping mechanism 30 is opened, four stainless steel balls inside the three-way valve 56 slide down along a ramp, the pressure to the valve inlet 562 of the valve body 561 is F =2 × (M1 + M2) g × sin θ, wherein 90 ° ≧ θ is ≧ 0 °, M1 is the mass of the movable member 564, and M2 is the mass of the driving unit 565, and the unit is gram. At this time, the steel ball at the bottom of the right forms a seal with the valve inlet 562, and the water in the water storage tank 12 enters from the other valve inlet 562 and flows out from the valve outlet 563 to enter the sewage tank 32, so that the sewage 70 flows back to the water storage tank 12 when the sewage in the sewage tank 32 flows over the floating body 331.

When the car washing operation is performed by the washing device in the vertical state, the internal state of the three-way valve 56 is as shown in fig. 20, when the sewage extraction mechanism 30 is opened, the four stainless steel balls inside the three-way valve 56 slide down the ramp, the right-most steel ball forms a seal with the valve inlet 562, the pressure on the valve inlet 562 is F =2 × (M1 + M2) g, at this time, the sewage in the water storage tank 12 enters from the valve inlet 562 and flows out from the valve outlet 563 to enter the sewage tank 32, and when the sewage 70 in the sewage tank 32 overflows the floating body 331, the sewage 70 flows back to the water storage tank 12.

When the vehicle washing operation is performed in the horizontal state of the washing device, the internal state of the three-way valve 56 is as shown in fig. 21, when the sewage pumping mechanism 30 is opened, the four stainless steel balls inside the three-way valve 56 cannot seal the two valve inlets 562 and the valve outlet 563, at this time, the sewage 70 in the water storage tank 12 enters from the two valve inlets 562, flows out from the valve outlet 563, enters the sewage tank 32, and when the sewage in the sewage tank 32 flows over the floating body 331, the sewage 70 flows back to the water storage tank 12.

In another possible embodiment, as shown in fig. 22, said movable members 564 comprise a first movable member 5641 and a second movable member 5642 for blocking the passage between said two valve inlets 562 and said two water ducts 531, respectively; the drive unit 565 is one, located between the first and second moving parts 5641 and 5642; the three-way valve 56 is connected with a swing lever 566, and the swing lever 566 is connected with a driving unit 565; under the oscillating action of the oscillating rod 566, the oscillating rod 566 can drive the driving unit 565 to move towards one of the movable pieces 564 to close off the corresponding valve inlet 562, and the other movable piece 564 is far away from the other valve inlet 562.

In the embodiment, the pendulum 567 externally connected with the swinging rod 566 drives the swinging rod 566 to swing left and right under the action of gravity, and further drives the driving unit 565 connected to the lower part of the swinging rod 566 to move in the opposite direction, so as to push the movable piece 564 to move towards the arc surface of the valve inlet 562, based on the principle of tangential sealing with the arc conical surface, along with the switching of angles during cleaning, the valve inlets 562 sealed by the movable pieces 564 inside the valve body 561 are different, thereby realizing the switching of extracting two sewage, the switching is fast and high, the failure rate is low, the cost is low, the material consumption is simple, and the working efficiency is high.

The three-way valve 56 of the present embodiment is opened and closed by freely swinging the swinging rod 566 in the valve body 561, and the steps are as follows: due to the extrusion of the driving unit 565 below the swinging rod 566, the movable piece 564 on one of the two sides forms a seal with the inner wall of the tapered pipeline, so that the valve inlet 562 is switched between open and closed states, at this time, the driving unit 565 below the swinging rod 566 blocks the valve inlet 562, and the other two channel ports are communicated, so that the liquid flows through the two channel ports, and the liquid is conveyed.

Further, the inner cavity wall surface of the valve body 561 is formed with a tapered portion 5612 for moving the movable piece 564 toward the corresponding valve inlet 562. The provision of tapered portion 5612 facilitates displacement of moveable member 564 towards a corresponding valve inlet 562.

According to one embodiment of the invention, the cleaning device further comprises a waste water tank 32, via which waste water 70 in the waste water tank 32 can be sucked into the waste water tank 32.

In one possible embodiment of the suction power unit, as shown in fig. 10 and 23, the suction power unit includes a sewage pump 31 disposed at an upstream side of the sewage tank 32, the cleaning apparatus further includes a motor for driving the sewage pump 31 to perform a suction motion, the number of the sewage pumps 31 is two, the first sewage suction port 1241 and the second sewage suction port 1242 are respectively communicated with the two sewage pumps 31 through a suction passage 301, and outlets of the two sewage pumps 31 are respectively communicated with the sewage tank 32 through a sewage inlet pipe.

Specifically, the water inlet 311 of the sewage pump 31 is communicated with the first/second sewage suction ports 1241, 1242 through the suction passage 301, and the water outlet 312 of the sewage pump 31 is communicated with the sewage tank 32; of course, in other embodiments, there may be one sewage pump 31.

In this embodiment, the sewage pump 31 pumps the sewage in the storage tank 12 directly and discharges the sewage into the sewage tank 32. In other embodiments, the waste water tank 32 may be omitted, and the waste water 70 is directly discharged to a designated position through the water outlet 312 of the waste water pump 31. For example, a hose is connected to a water outlet of the sewage pump 31, and the sewage 70 is discharged into a predetermined container placed on the ground through the hose, thereby preventing the sewage 70 from being scattered at will to pollute the environment.

The sewage pumping mechanism 30 is required to absorb the sewage 70 and allow the sewage 70 and fine sand to pass through without damaging the sewage pump 31 when pumping the sewage 70 in the storage tank 12, and the flow direction of the sewage 70 is preferably one-way and cannot flow back, and a certain pressure and a sufficient flow rate should be ensured during pumping to ensure the pumping efficiency. In addition, the service life is an important technical consideration, and the life of the sewage pump 31 is usually more than 80 hours. Therefore, in the embodiment of fig. 10 and 23, the sewage pump 31 includes a peristaltic pump, which can satisfy the above requirements, and then when the cleaning apparatus is used under multi-angle working conditions, the sewage pumping mechanism 30 can still work normally, which is a dual requirement of multi-angle cleaning and rapid sewage recovery 70. Of course, the sewage pump 31 may also comprise a diaphragm pump, and it is emphasized that, in the diaphragm pump used herein, the requirements of the diaphragm should meet or nearly meet the requirements of the above-mentioned items for the sewage pumping mechanism 30. In addition, a filtering device can be added at the upstream of the diaphragm pump, so that the corrosion of impurities such as fine sand grains to the diaphragm pump after long-time use is avoided. Further, in the case where the filter device is provided, the diaphragm pump may be replaced with another type of water pump, and is not particularly limited herein.

Because the both ends of aqua storage tank 12 are equipped with first soil pick-up mouth 1241 and second soil pick-up mouth 1242 respectively, although can accelerate suction efficiency, the inventor notices, in the use, because cleaning equipment has the multi-angle service mode, can appear following problem: the first sewage suction port 1241 and the second sewage suction port 1242 at the two ends of the water storage tank 12 are vertically arranged, that is, the first sewage suction port 1241 and the second sewage suction port 1242 have a height difference in the vertical direction, at this time, the sewage 70 flows to the sewage suction port below under the action of gravity, in the embodiment of only one sewage pump 31 shown in fig. 10, because only one sewage pump 31 is used for respectively sucking the first sewage suction port 1241 and the second sewage suction port 1242, at this time, the air suction of the sewage suction port above the water storage tank 12 in the gravity direction is easier than the suction of the sewage 70 of the water storage tank 12 below the water storage tank 12, and an air pressure difference cannot be formed, which results in difficulty in sucking the sewage 70 below the water storage tank 12 in the gravity direction.

Therefore, in the embodiment shown in fig. 10, the above-described switching mechanism 50 is also provided to the cleaning apparatus. In a state that both ends of the cleaner head 10 of the cleaning apparatus are substantially horizontal, the sewage pump 31 simultaneously sucks the sewage 70 from the first and second sewage suction ports 1241 and 1242, which is advantageous for accelerating the suction of the sewage 70; when the first sewage suction port 1241 and the second sewage suction port 1242 at the two ends of the water storage tank 12 are different in height in the vertical direction, the sewage 70 is collected to the sewage suction port with a lower position due to the gravity, so that the sewage pump 31 is facilitated to rapidly suck the sewage 70 in the water storage tank 12 under the operation of the switching mechanism 50.

In the embodiment of fig. 23 having two sewage pumps 31, the switching mechanism 50 may be disposed on the cleaning apparatus, or the sewage recovery effect and the use in different postures of the cleaning head 10 may be achieved by controlling the on/off of the sewage pump 31 communicating with the corresponding sewage suction port without providing the switching mechanism 50, without limitation.

In another possible embodiment of the suction power unit, the suction power unit comprises a negative pressure generating mechanism 35 arranged on the downstream side of the waste water tank 32, the negative pressure generating mechanism comprising an air pump, and the cleaning device comprises a motor driving the air pump to perform a suction movement, the inlet of the air pump being in communication with the waste water tank 32. That is, the waste water tank 32 is interposed between the negative pressure generating mechanism 35 and the sewage suction port, and the negative pressure generating mechanism 35 is used to form a vacuum inside the waste water tank 32, so that the waste water 70 is continuously drawn into the waste water tank 32 and stored therein. In this embodiment, the sewage 70 does not enter the negative pressure generating mechanism 35.

In one embodiment, as shown in fig. 24, the suction ports 124 at both ends of the storage tank 12 are respectively communicated with the waste water tank 32 through the suction passage 301, the air inlet 351 of the negative pressure generating mechanism 35 is communicated with the waste water tank 32, and the air outlet 352 of the negative pressure generating mechanism 35 is communicated with the storage tank 12. In this embodiment, the negative pressure generating mechanism 35 may be any device capable of forming a vacuum negative pressure inside the sewage tank 32, and specifically, the negative pressure generating mechanism 35 may be a diaphragm pump, a peristaltic pump, a plunger pump, or an electromagnetic pump, and the number thereof may be one or two. In the present invention, a filtering structure may be added between the sump 32 and the air inlet 351 of the air pump to improve the lifespan of the air pump.

In another embodiment, as shown in fig. 25, the first and second suction ports 1241 and 1242 at both ends of the reservoir tank 12 are respectively communicated with the waste water tank 32 through the suction passage 301, and the inlet of the negative pressure generating mechanism 35 is communicated with the waste water tank 32, and the negative pressure generating mechanism 35 is a blower fan.

According to one embodiment of the invention, the cleaning apparatus has at least a first operating position in which the height of the hand-held end from the floor surface is greater than the height of the working brush 11 from the floor surface, and a second operating position in which the height of the hand-held end from the floor surface is less than the height of the working brush 11 from the floor surface; the sewage 70 transferred into the sewage tank 32 can apply pressure to the air in the sewage tank 32, the sewage tank 32 is provided with an exhaust structure 33, the exhaust structure 33 is provided with an exhaust port 333 for conveying the air in the sewage tank 32 to be led out, and the exhaust port 333 adjusts the position of the exhaust port 333 in response to the change of the working position of the cleaning device, so that the exhaust port 333 is exposed above the sewage level in the sewage tank 32.

In the embodiment shown in fig. 10 and 23 to 25, the air outlet 333 is provided in the foul water tank 32, the air discharging structure 33 includes a float 331, and a connecting pipe 334 connected to the float 331, the float 331 has a vent passage, one end of which forms the air outlet 333 and is located above the liquid level in the foul water tank 32, and the other end of which discharges the air to the outside through the connecting pipe 334.

Specifically, the float 331 has a density lower than that of the sewage 70 and floats on the surface of the sewage 70, and the gas in the sewage tank 32 is introduced into and discharged from the sewage tank 32 through the gas outlet 333.

Further, in order to prevent the sewage 70 collected in the sewage tank 32 from entering the exhaust port 333, a weight 332 is provided on the floating body 331, the weight 332 is located at the end of the connecting pipe 334, and the weight 332 has a gravity smaller than the buoyancy of the floating body 331 in the sewage 70.

Specifically, the weight 332 is disposed on a side surface of the floating body 331 opposite to the exhaust port 333, and the gravity borne by the weight 332 is smaller than the buoyancy of the floating body 331 in the sewage 70. Thus, the exhaust 333 is always able to face away from the waste water 70 when the cleaning apparatus is in different states of use. Preferably, the connection pipe 334 has a certain flexibility, so that the float 331 is not restricted by the connection pipe 334 when adjusting the position of the exhaust port 333 when the cleaning apparatus is changed in angle.

As shown in fig. 26 and 27, when the weight 332 is disposed on the floating body 331, and the cleaning device is at different working angles, the opening of the air outlet 333 can always face away from the sewage 70, so as to prevent the sewage 70 from entering the connecting pipe 334. As shown in fig. 27, the cleaning apparatus is inclined with respect to fig. 26, and at this time, the connection pipe 334 is bent by the weight 332, and the opening of the air outlet 333 is disposed upward in the vertical direction.

Preferably, the float 331 is a hollow structure having an interior cavity. The exhaust port 333 is communicated with the inner cavity of the hollow floating body 331, and is located on the same diameter of the floating body 331 and located on two sides of the spherical center of the floating body 331 together with the weight block 332. One end of the connection tube 334 is inserted into the inner cavity of the hollow float 331. In this embodiment, the float 331 is not limited to the hollow structure as long as the vent 333 and the connection pipe 334 can communicate with each other. In this embodiment, the connecting tube 334 may pass through the weight 332 and be inserted into the floating body 331, but the connecting tube 334 may also be inserted into the floating body 331 from another position of the floating body 331, and is not limited herein.

In the cleaning apparatus of the present invention, in the embodiment shown in fig. 10 and 23, the air in the waste water tank 32 can be communicated to the air return port 125 of the water storage tank 12 through the air return pipe 34, so that the inner space of the waste water tank 32 is communicated with the water storage tank 12. Therefore, the air in the sewage tank 32 can flow back into the water storage tank 12, so that a large amount of sewage 70 can be prevented from flowing back into the water storage tank 12 due to overlarge pressure in the sewage tank 32, the damage of the sewage tank 32 due to the overlarge pressure in the sewage tank 32 can be avoided, and meanwhile, the sewage 70 can be prevented from dripping from the sewage tank 32; in addition, the air in the sewage tank 32 flows back into the water storage tank 12 to increase the pressure in the water storage tank 12 to a certain extent, which is beneficial to quickly extracting the sewage 70 in the water storage tank 12.

In the embodiment shown in fig. 24, the connecting pipe 334 of the exhaust structure 33 is communicated with the air inlet 351 of the negative pressure generating mechanism 35 through a pipeline, when the negative pressure generating mechanism 35 operates, the air in the sewage tank 32 is pumped through the air outlet 333, and the exhaust structure 33 can ensure that the negative pressure generating mechanism 35 can reliably pump the air in the sewage tank 32 to form vacuum negative pressure, so as to prevent the sewage 70 from accidentally entering the negative pressure generating mechanism 35.

In addition, the inventor also considers that even if the float 331 is provided to prevent the sewage 70 from entering the negative pressure generating mechanism 35, the gas in the sewage tank 32 inevitably contains a small amount of moisture, which results in a small amount of water contained in the gas discharged from the negative pressure generating mechanism 35, which may pollute the environment. Therefore, in the embodiment, the air outlet 352 of the negative pressure generating mechanism 35 is also communicated with the water storage tank 12 through the air return pipe 34, and by the above means, on one hand, redundant water vapor is discharged into the water storage tank 12, so as to avoid environmental pollution; on the other hand, after the gas discharged from the negative pressure generating mechanism 35 enters the water storage tank 12, the pressure inside the water storage tank 12 is increased to a certain extent, which is beneficial for the negative pressure generating mechanism 35 to draw the sewage inside the water storage tank 12 as soon as possible.

When the air return pipe 34 is connected to the water storage tank 12, the air return pipe 34 can be directly inserted into the inner cavity of the water storage tank 12 through the air return opening 125. Of course, in other embodiments, the air return pipe 34 may be connected to the air return port 125 of the water storage tank 12 through an interface, which is not limited herein.

In the embodiment shown in fig. 28, the exhaust outlet 333 is provided in the waste water tank 32, and the waste water tank 32 can be rotatably arranged in response to different operating positions of the washing apparatus, so that the exhaust outlet 333 is located above the liquid level in the waste water tank 32 in the different operating positions.

Specifically, the handheld frame 20 is provided with the adaptive joint 16, and the sewage tank 32 is connected to the handheld frame 20 through the adaptive joint 16, so that the sewage tank 32 is always kept parallel to the horizontal plane. In this way, in the "multi-dimensional" washing, the wastewater tank 32 is always kept parallel to the horizontal plane, which is advantageous for maintaining the posture of the float 331 of the exhaust structure 33, thereby preventing the backflow and leakage of the wastewater 70.

As can be seen from the above description, the cleaning apparatus of this embodiment, when the two ends of the water storage tank 12 are vertically the same, can ensure the advantage of rapid absorption of the sewage 70. It will be appreciated that when the two ends of the reservoir 12 are vertically different, the sewage will naturally flow towards one end, again to facilitate rapid absorption of the sewage 70. And when the heights of the two ends of the water storage tank 12 in the vertical direction are changed, the working angle of the cleaning equipment is changed. Therefore, the cleaning equipment of this embodiment can satisfy the dual demand that multi-angle washing and compromise quick recovery sewage 70.

In the using process, a working condition that the heights of the two ends of the water storage tank 12 are the same in the vertical direction may also occur, and in order to ensure that the sewage 70 can be absorbed quickly under this condition, as shown in fig. 29, the middle part of the bottom wall of the water storage tank 12 is high, and the two ends are low so that the sewage 70 can flow from the middle part to the first sewage suction port 1241 and the second sewage suction port 1242 at the two ends. More specifically, referring to fig. 30 in combination with fig. 29, the water storage tank 12 includes a bottom wall 121 and a side wall 122 connected to the bottom wall 121, the side wall 122 and the bottom wall 121 enclose an inner cavity of the water storage tank 12, wherein, in the axial direction of the working brush 11, the bottom wall 121 is high in the middle and low at both ends, so that the sewage 70 can flow from the middle to both ends. Because the middle part of the bottom wall of the water storage tank 12 is high and the two ends are low, when the two ends of the water storage tank 12 are the same in height in the vertical direction, the sewage 70 flows to the sewage suction ports 124 at the two ends at the same time, thereby being beneficial to sucking the sewage 70.

As shown in fig. 29, the bottom wall 121 of the water storage tank 12 has a high middle portion and low ends, and the bottom wall 121 includes a first flow guide surface 126 and a second flow guide surface 127, the first flow guide surface 126 and the second flow guide surface 127 are inclined surfaces, respectively, in the depth direction (vertical direction in fig. 29) of the water storage tank 12, a top end 12a of the inclined surface is closer to the middle portion of the water storage tank 12 than a bottom end 12b of the inclined surface, the two inclined surfaces are arranged in the length direction X of the working brush 11, and the top ends 12a of the two inclined surfaces are connected. Therefore, from the connection between the first flow guide surface 126 and the second flow guide surface 127, the sewage 70 is more likely to flow toward the end of the first flow guide surface 126 away from the second flow guide surface 127 and toward the end of the second flow guide surface 127 away from the first flow guide surface 126. Referring to fig. 23 and 29, the first and second soil suction ports 1241 and 1242 are disposed on the side wall 122 of the water storage tank 12, and the two soil suction ports 124 are respectively close to one end of the first drainage surface 126 far from the second drainage surface 127 and one end of the second drainage surface 127 far from the first drainage surface 126.

In other embodiments, as shown in fig. 31 in combination with fig. 29, the first and second dirt suction ports 1241, 1242 may be provided on the first and second guide surfaces 126, 127, respectively. Preferably, the two soil suction ports 124 are respectively disposed at a position near one end of the first guide surface 126 away from the second guide surface 127 and a position near one end of the second guide surface 127 away from the first guide surface 126. In other words, in the present embodiment, the first and second suction ports 1241 and 1242 are provided at positions close to the ends distant from each other in the first and second suction surfaces 126 and 127, respectively.

It should be emphasized that the middle portion of the bottom wall 121 of the storage tank 12 is high and both ends are low, which is not limited to the above-mentioned embodiment, and any structure for facilitating the flow of the sewage 70 from the middle portion of the bottom wall 121 of the storage tank 12 to both sides may be adopted. For example, the inclined surface may be a wavy surface, and a water chute is formed between adjacent wave crests.

As shown in fig. 32, the air return opening 125 of the reservoir tank 12 opens in the side wall 122 of the reservoir tank 12, and the air return opening 125 is located between the first dirt suction opening 1241 and the second dirt suction opening 1242 in the axial direction of the work brush 11. That is, the return air opening 125 is opened at a middle position of the side wall 122 of the storage tank 12 in the axial direction of the operating brush 11, so that a small amount of the contaminated water 70 is fed into the storage tank 12 and the flow of the contaminated water 70 to the first and second soil suction openings 1241 and 1242 at both ends can be accelerated by air. It should be emphasized that the return opening 125 of the reservoir 12 opens in the side wall 122 of the reservoir 12, but is also applicable to a flat bottom wall 121 of the reservoir 12.

Referring to fig. 33, when the cleaning apparatus of this embodiment is used, water is sprayed onto the brush bristles 112 through the water supply system 60, the working brush 11 rotates counterclockwise, the wiper strip 13 wipes the sewage 70 on the brush bristles 112 into the water storage tank 12, and the sewage 70 flows toward both ends of the water storage tank 12 and is pumped by the two sewage pumps 31 to the sewage tank 32. The flow direction of the clean water and the waste water 70 from the water supply system 60 can be seen by the arrows in the figure. The air in the foul water tank 32 is returned to the sump 12 through the connection pipe 334. In the embodiment shown in fig. 32, the sewage 70 is drawn from the first and second suction ports 1241 and 1242 of the bottom wall 121 of the sump 12, and then pumped by the two sewage pumps 31 to the sewage tank 32. The flow direction of the clean water and the waste water 70 from the water supply system 60 can be seen by the arrows in the figure. The air in the foul water tank 32 is returned to the sump 12 through the connection pipe 334.

As shown in fig. 33, on the basis of the cleaning apparatus of the embodiment shown in fig. 10, a water supply system 60 is further provided on the hand-held frame 20. The water supply system 60 includes a cleaning liquid tank 61 and a cleaning liquid pump 62, wherein the cleaning liquid tank 61 is also disposed on the handheld frame 20, and the cleaning liquid pump 62 may be disposed separately from the handheld frame 20 or also disposed on the handheld frame 20. The cleaning liquid pump 62 is connected with a liquid pumping pipeline 63 and a spraying pipeline 64, wherein the liquid pumping pipeline 63 extends into the cleaning liquid tank 61; the nozzle 641 of the injection conduit 64 is located on one side of the bristles 112, as shown in FIG. 32. So, the cleaning equipment of this embodiment only can accomplish the washing under the automobile body surface multi-angle operating mode through the liquid that stores in the cleaning solution case 61, need not carry a large amount of water, and it is very convenient to use

Referring to fig. 34, another embodiment of the cleaning apparatus of the present invention is different from the embodiment of fig. 24 in that the structure of the sewage pumping mechanism 30 is similar to that of the water storage tank 12, i.e., the bottom wall of the water storage tank 12 is high in the middle and low at both ends, and sewage 70 can flow to both ends to facilitate the suction of the sewage 70.

In this embodiment, the sewage pumping mechanism 30 includes two sewage tanks 32 and two negative pressure generating mechanisms 35, wherein the two sewage tanks 32 are respectively communicated with the two sewage suction ports 124, and the two negative pressure generating mechanisms 35 are respectively communicated with the inner spaces of the two sewage tanks 32. That is, each of the sewage suction ports 124 is separately provided with the sewage tank 32 and the negative pressure generating mechanism 35, so that the sewage 70 in the storage tank 12 can be efficiently sucked.

The two waste water tanks 32 may be formed by dividing the inside of a larger-sized tank into two parts by providing a partition in the tank, or may be two tanks separated from each other, which is not limited in particular. The type of negative pressure generating mechanism 35 is not limited to include a large diaphragm pump, a peristaltic pump, a plunger pump, an electromagnetic pump, or a fan.

In addition, as in the present embodiment, the exhaust structure 33 may be disposed in each waste water tank 32, and the communication manner between the exhaust structure 33 and the corresponding negative pressure generating mechanism 35 is similar to that in fig. 24, and is not repeated.

In addition, the air outlet 352 of each negative pressure generating mechanism 35 is communicated with the same air return port 125 of the water storage tank 12 through the air return pipe 34, so that on one hand, redundant water vapor is discharged into the water storage tank 12, and the environment pollution is avoided; on the other hand, the gas discharged from the negative pressure generating mechanism 35 enters the water storage tank 12, so that the pressure inside the water storage tank 12 is increased to a certain extent, and the negative pressure generating mechanism 35 is favorable for extracting the water inside the water storage tank 12 as soon as possible. Each negative pressure generating mechanism 35 may also be separately communicated with a different return air opening 125 of the reservoir 12.

The present invention also provides a cleaning apparatus comprising a handpiece 20 and a cleaning head 10, wherein: the hand holder 20 is extended along the longitudinal direction thereof; the cleaning head 10 comprises a cleaning head shell, a working brush 11 rotatably connected on the cleaning head shell, a water storage tank 12 used for collecting the sewage 70, and a sewage suction port 124 used for recovering the sewage 70 in the water storage tank 12, wherein a decontamination unit is arranged on the cleaning head shell and is configured to act on the working brush so as to remove and guide the sewage 70 on the working brush to the water storage tank 12; as shown in fig. 36, the suction port 124 includes a first suction port 1241 provided at one end of the storage tank 12 in the longitudinal direction, and the first suction port 1241 is configured to open an inner cavity of the storage tank 12 to a free end in the longitudinal direction.

Specifically, in this embodiment, the decontamination unit may be, for example, the wiper strip 13 in the first embodiment.

In this embodiment, the first soil intake opening 1241 is configured such that the cavity of the reservoir 12 is open to the free end in the length direction, which means that sewage can flow out in a certain direction, rather than that the cavity of the reservoir 12 has no physical structure between the direction and the outside. The free end of the interior chamber of the reservoir 12 in the longitudinal direction is considered open if the free end of the reservoir 12 in the longitudinal direction does not form a continuous solid structure that completely covers that direction so that the waste water 70 cannot flow out in that direction. By adopting the structure, the arrangement of a sewage pumping mechanism is omitted, and when the cleaning head 10 is operated at multiple angles, sewage collected into the water storage tank 12 through the decontamination unit can be discharged from the first sewage suction port 1241 and the second sewage suction port 1242, so that the structure of the cleaning equipment is simplified, and the use convenience is improved.
