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 gradually increased. Common car washing methods at present comprise: 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 needs at least one barrel of water, lifting a barrel of water upstairs and downstairs is inconvenient to carry, and a lot of troubles are added to car washing of a user every time, so that the household car washer is troublesome and not suitable for urban people. There is also a water-spraying type domestic car washer using a manual air pump as a power source, which not only has the disadvantages of time and labor waste, but also is inconvenient to 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.

In the related art, portable pressure cleaning apparatuses have come into use, which generally wash the surface of an object by generating a high-pressure water stream by, for example, a plunger pump. Although, the portable pressure washer apparatus reduces the amount of water used to some extent relative to the aforementioned cleaning methods. However, in the conventional portable pressure cleaning equipment, the pump, the motor, the battery pack and the spray gun are integrated, so that in order to achieve a better cleaning effect, the requirements on water quantity and water outlet pressure are still high, and the pump and the motor with high power need to be selected. In the cleaning process, the pump and the motor with large power are selected, so that the endurance time can be shortened, the capacity of a power supply battery pack can be increased generally to solve the problem, the weight of the machine is increased, the user is hard to hold, and the human-computer interaction experience is poor.

Furthermore, the portable pressure washer device cannot be used effectively when washing, for example, automobiles, kitchens and walls. In particular, for example, in some wash scenarios where multi-angle, multi-wash surface washing is desired, the aforementioned portable pressure washer devices still do not provide effective access to each surface to be washed, such as a vehicle roof or wash surfaces that are prohibited from washing using pressurized water flow. For another example, in other washing scenes, the user needs to hold the portable pressure washing device on the surface to be washed and control the portable pressure washing device to wash in 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 washing device, the operation experience is not good, the cleaning effect of the single pressure water flow is not good, and the user needs to use the washing cloth to clean the surface in a wiping manner, which is time-consuming and labor-consuming. In still other cleaning scenarios, after the pressure water flow of the pressure cleaning device is used to strip off the dirt, the dirt will flow downward with the water flow, and thus the originally unsoiled or cleaned surface will be contaminated, and a second cleaning is required. In addition, the place of user's carwash is restricted in the city, and the water source is difficult to guarantee, and in addition, the clearance of the sewage after the carwash also is a difficult problem of puzzlement user. This results in the conventional portable pressure washing apparatus having limited workability and washing effect.

Therefore, it is necessary to provide a portable cleaning apparatus, which can break through the limitation of the application scenario of the conventional portable pressure cleaning apparatus, realize multi-cleaning-surface and multi-angle cleaning under complex working conditions, and has lower requirements on water volume and water pressure compared with the conventional portable cleaning apparatus, and a better cleaning effect. Meanwhile, sewage can be effectively collected, the occurrence of the condition of secondary pollution is avoided, and the operation convenience and the cleaning effect of the portable cleaning equipment are improved.

In the embodiment of the present application, a cleaning device for cleaning a vehicle is taken as an example to describe a structure of the portable cleaning device in the present application, and in other embodiments, the portable cleaning device may also be used to clean other objects such as a door, a window, a wall, a floor glass, and the like.

In the present embodiment, the term "multiple cleaning surfaces" is to be understood as meaning that the cleaning head 20 of the portable cleaning device is 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 20 of the portable cleaning device can present a plurality of different using postures as shown in fig. 1, 3 and 5. For example, referring to fig. 9, if a horizontal plane (ground) is used as a reference plane, the angle of the length direction X of the cleaning head 20 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 20 in the vertical direction Z (i.e., the gravity direction) is different due to different slopes of different cleaning surfaces.

"Multi-angular" is understood to mean that the portable cleaning apparatus has a plurality of operating positions in which the distance between the user's hand-held end of the portable cleaning apparatus and the floor surface 101 and the distance between the cleaning head and the floor surface 101 exhibit different results when actually cleaning. For example, the user can hold the grip portion 12, and the cleaning head 20 can be cleaned in a manner such that the cleaning head is entirely at an upper position (as shown in fig. 8), a lower position (as shown in fig. 1 and 2), or a position at which the cleaning head and the grip portion 12 are substantially at the same height (as shown in fig. 5) in the vertical direction Z with respect to the grip portion 12, and the above three modes of use can be used in combination.

As shown in fig. 8, the cleaning head 20 may be raised in the vertical direction Z as a whole with respect to the grip portion 12, while one end of the length direction X of the cleaning head 20 (e.g., the end closer to the inner side of the drawing in fig. 8) is raised in the vertical direction Z with respect to the other end of the cleaning head 20 so that the length direction X of the cleaning head 20 forms an angle with the horizontal plane.

As shown in fig. 9 and 10, the present application provides a portable cleaning apparatus including: a cleaning head 20; a fluid recovery mechanism having a dirty liquid container 40 and a fluid recovery power source by which dirty fluid 70 generated when the cleaning head 20 cleans a surface to be cleaned can be sucked into the dirty liquid container 40; a holding part 12 for a user to operate and hold the portable cleaning device for cleaning; the portable cleaning apparatus has at least: a first working position (shown in figure 2) that the height of the holding part 12 from the ground is greater than that of the cleaning head 20 from the ground, and a second working position (shown in figure 8) that the height of the holding part 12 from the ground is less than that of the cleaning head 20 from the ground; wherein the dirty liquid container 40 is provided with an exhaust structure, the exhaust structure comprises an exhaust port 622 for adjusting the pressure in the inner cavity of the dirty liquid container 40, the portable cleaning apparatus is in the first working position or the second working position, and the exhaust port 622 is configured to be exposed above the liquid level of the dirty liquid in the dirty liquid container 40.

The application provides a portable cleaning device for carrying out cleaning work. As shown in fig. 9, the end corresponding to the cleaning head 20 is defined as a front end (distal end), for example, the front end of the portable washing apparatus refers to the end of the user far from the user when the user performs a washing operation using the portable washing apparatus. Accordingly, the grip portion 12 held by the user is defined as a rear end (proximal end), for example, the proximal end of the portable cleaning apparatus refers to the end of the portable cleaning apparatus close to the user when the user performs a cleaning operation using the portable cleaning apparatus. It is to be understood that the above definitions are for illustration purposes only and are not to be construed as limitations of the present application.

Specifically, as shown in fig. 9, the portable washing apparatus of the present application includes a holding bar 10, the holding bar 10 extending substantially in the longitudinal direction Y between a front end and a rear end, a cleaning head 20 being disposed at the front end of the holding bar 10, the rear end of the holding bar 10 being a grip portion 12, the grip portion 12 being for a user to operate the grip. In the present embodiment, one or more operation elements 14 are disposed on the grip portion 12, and the user can control the portable cleaning device to be in an operation state or a non-operation state through the operation elements 14, for example, the mode of the portable cleaning device can be controlled through the operation elements 14. The dirty liquid container 40 is used for receiving dirty fluid 70 generated when the cleaning head 20 cleans a surface to be cleaned. It is understood that in other embodiments, the holding portion 12 is not necessarily located at the rear end of the holding rod 10, and for example, may be located near the rear end of the holding rod 10, which is not limited herein.

The retaining bar 10 includes a retaining bar housing (not shown) in which functional components such as a fluid recovery power source for recovering the dirty fluid 70 generated by the cleaning head 20 to the dirty liquid container 40, and pipes having different functions such as a recovery pipe, are protectively arranged. In the present embodiment, the dirty liquid container 40 is detachably connected to the holding rod housing, but in another embodiment, the dirty liquid container 40 may be integrally formed on the holding rod housing, for example, the holding rod housing is an injection molding member, and the dirty liquid container 40 is formed during the injection molding process, which is not limited herein.

The cleaning head 20 may be fixed to the front end of the holding bar 10, and of course, the cleaning head 20 may be movably connected to the front end of the holding bar 10, but it is preferable that the cleaning head 20 should be limited to a certain movable range in consideration of a problem of entanglement of a pipe line connecting the cleaning head 20 and the contaminated liquid container 40. For example, in the present embodiment, the cleaning head 20 is pivotally connected to the front end of the holder lever housing about a pivot axis by a hinge so that the cleaning head 20 can swing within a predetermined range, and the swinging of the cleaning head 20 about the pivot axis enables better cleaning possibilities also at positions that are difficult to reach, i.e., the cleaning apparatus can be repositioned to some extent relative to the surface to be cleaned, thereby achieving better cleaning results. Specifically, the pivot axis is transversely disposed relative to the longitudinal axis of the retainer bar 10, e.g., in some embodiments, the pivot axis is perpendicular to the longitudinal axis of the retainer bar 10, and in other embodiments, the pivot axis may be disposed at an acute angle relative to the longitudinal axis of the retainer bar 10 to accommodate "multi-dimensional" cleaning conditions of multiple angles and cleaning surfaces. Further, the retaining rod housing may be provided with locking means for locking the cleaning head 20 to the retaining rod housing such that the cleaning head 20 is non-rotatable relative to the retaining rod housing.

The fluid recycling mechanism of the present application is used for sucking dirty fluid 70 generated by cleaning a surface to be cleaned by the cleaning head 20 into the dirty liquid container 40, and particularly, sucking the dirty fluid 70 into the dirty liquid container 40 by the fluid recycling power source.

In the present application, the dirty liquid container 40 is provided with an exhaust structure, the exhaust structure comprises an exhaust port 622 capable of adjusting the pressure of the inner cavity of the dirty liquid container 40, the portable cleaning device is in the first working position or the second working position, and the exhaust port 622 is configured to be exposed above the liquid level of the dirty liquid in the dirty liquid container 40.

The application of the portable cleaning equipment can be used for breaking the limitation of the application scene of the traditional portable pressure cleaning equipment, realizing multi-angle cleaning under complex working conditions and achieving a better cleaning effect. Meanwhile, sewage can be effectively collected, secondary pollution is avoided, and operation convenience and cleaning effect of the portable cleaning equipment are improved.

In one possible embodiment of the venting structure, as shown in fig. 10, the vent 622 is located in the dirty liquid container 40, according to an embodiment of the present application, and the venting structure further comprises: a float 62 positioned in the dirty liquid container 40, and an exhaust port 622 provided on the float 62; and an exhaust pipe 66 connected to the float 62, one end of the exhaust pipe 66 being in communication with the outside of the dirty liquid container 40, and the other end thereof extending into the dirty liquid container 40 and being in communication with an exhaust port 622, wherein the gas in the dirty liquid container 40 can be exhausted to the outside of the dirty liquid container 40 through the exhaust port 622 and the exhaust pipe 66.

Specifically, a weight block 64 is disposed on the float 62, the weight block 64 is disposed opposite to the exhaust port 622, and the buoyancy of the float 62 is greater than or equal to the gravity of the weight block 64. It will be appreciated that as the dirty fluid 70 is continuously delivered into the dirty liquid container 40, the float 62 will float up with the level of the dirty fluid 70, and due to the changing attitude of the user operating the portable cleaning device, the dirty fluid 70 will tend to overflow through the vent 622 into the vent line 66, which can affect the user's experience. When the weight 64 is opposite to the exhaust port 622 of the float 62, no matter how the working position of the portable cleaning apparatus changes, as shown in fig. 11, the exhaust port 622 of the float 62 is always kept upward under the restriction of the weight 64, so that the dirty fluid 70 is prevented from entering the exhaust port 622 and causing the dirty fluid to overflow. Therefore, the air pressure in the dirty liquid container 40 can be kept stable, the phenomenon that the dirty fluid 70 flows back due to the fact that the air pressure in the dirty liquid container 40 is too large is avoided, the phenomenon that a large amount of dirty fluid 70 overflows through the exhaust pipeline 66 is avoided, and user experience and safety and reliability of a machine are improved.

In another embodiment, referring to fig. 10, one end of the exhaust pipe 66 penetrates the float 62 along the radial direction of the float 62 and extends to the exhaust port 622, and the weight block 64 is disposed on the exhaust pipe 66.

Specifically, the other end of the exhaust pipe 66 penetrates the float 62 along the radial direction of the float 62 and extends to the exhaust port 622, and the weight 64 is disposed on the exhaust pipe 66, for example, in the present embodiment, the weight 64 can be sleeved on the exhaust pipe 66. It will be readily appreciated that the float 62 is of relatively light mass, such as may be made of plastic or other fibrous material, and the weight 64 is of relatively heavy mass, such as is typical of metallic materials. The weight block 64 made of different materials is directly connected to the float 62, so that the connection reliability is poor, and therefore, in the specific implementation, one end of the exhaust pipeline 66 penetrates through the float 62 and extends to the exhaust port 622, so that on one hand, a small amount of dirty fluid entering the float 62 from the exhaust port 622 is prevented from entering the exhaust pipeline 66, and on the other hand, the position of the weight block 64 is convenient to fix, so that the exhaust port 622 is opposite to the weight block 64.

While not wishing to be bound by theory, the inventors have discovered that the float 62 is restrained by the weight 64 such that the exhaust port 622 is directed upwardly, but that the exhaust line 66 may still be affected by the dirty fluid and swing to pull the float 62 during multiple angular shifts of the portable cleaning apparatus, causing the exhaust port 622 to be submerged or close to the surface of the dirty fluid 70.

Therefore, in order to solve this problem, the exhaust pipe 66 is configured to be adjustable in position angle with respect to the float 62 based on a change in the volume of the sewage collected in the sewage container 40, and the shore hardness of the exhaust pipe 66 is 30A to 40A. The vent line 66 of the present application is resiliently configured so that the portion of the vent line 66 extending into the dirty liquid reservoir 40 can oscillate as the float 62 floats, thereby avoiding the vent line 66 from "pulling" on the float 62, which could result in the vent port 622 being submerged in the dirty fluid 70.

Further studies have found that the material properties of the vent line 66, such as hardness, the mechanical dimensions of the vent line 66, such as diameter, directly affect whether the vent line 66 can oscillate as the float 62 floats, and at the same time, the venting rate and the venting flow rate of the vent line 66 need to be balanced. Therefore, the inventor finds that when the diameter of the exhaust pipeline 66 is greater than or equal to 2 mm and the shore hardness of the exhaust pipeline 66 is 30A-40A, the exhaust pipeline 66 can be ensured to swing along with the float 62, and the exhaust pipeline 66 cannot pull the float 62 to drive the float 62 to move, so that on one hand, the exhaust port 622 can be prevented from being immersed or close to the liquid level of the dirty fluid 70, and on the other hand, the exhaust rate and the exhaust amount are ensured to keep the air pressure in the dirty fluid container 40 stable. Preferably, the exhaust conduit 66 has a diameter of 3 mm.

In another possible embodiment of the air discharge structure, as shown in fig. 12, the air discharge opening 622 is opened in the dirty liquid container 40, and the dirty liquid container 40 provided with the air discharge opening 622 is rotatably/displaceably connected to the portable cleaning apparatus to adjust the position of the air discharge opening 622 in response to a change of the portable cleaning apparatus between the first operating position and the second operating position.

Specifically, the holding rod 10 is provided with an adaptive joint 16, and the dirty liquid container 40 is connected to the holding rod 10 via the adaptive joint 16 such that the exhaust port 622 on the dirty liquid container 40 is positioned above the liquid level of the dirty fluid in the dirty liquid container 40. In this manner, backflow and leakage of the dirty fluid 70 is prevented in the "multi-angle" cleaning.

In the present application, the exhaust port is exposed above the surface of the dirty fluid 70 in the dirty fluid container 40 when the portable cleaning apparatus is changed to different operating positions. Of course, the applicant should emphasize that the exhaust port 622 is immersed by the dirty fluid 70 and the instantaneous position of the portable cleaning device is changed when the dirty fluid container 40 is only full of the dirty fluid 70, and that the exhaust port 622 is only immersed for a moment, and that in other cases, the exhaust port 622 is substantially exposed above the surface of the dirty fluid 70 in the dirty fluid container 40.

According to an embodiment of the present application, as shown in fig. 13, the portable cleaning apparatus further includes a liquid supply mechanism including: a fluid container 30 capable of containing a cleaning fluid; a gravity unit 342 disposed in the fluid container 30, the gravity unit 342 having a liquid suction hole; a fluid supply pump 32 to provide the power to load cleaning fluid to the cleaning head 20; a liquid supply motor (not numbered) drives the liquid supply pump 32 to work, a liquid supply pipeline 344 is communicated with the liquid suction hole, and the liquid supply pump 32 supplies liquid to the cleaning head 20 through the liquid supply pipeline 344; wherein the buoyancy of the gravity unit 342 is smaller than the gravity of the gravity unit 342.

Specifically, as shown in fig. 14 and 15, the gravity unit 342 includes a gravity ball having a liquid suction hole (not shown), the gravity ball is disposed in the fluid container 30, one end of the liquid supply pipe 344 is connected to the gravity unit 342, the other end is connected to the cleaning head 20, and the liquid supply pump 32 is connected to the gravity unit 342 through a pipe for providing a fluid power to load the cleaning fluid to the cleaning head 20 to wet the cleaning head 20, so that the cleaning head 20 can clean the surface to be cleaned.

Wherein the buoyancy of the gravity unit 342 is smaller than the gravity of the gravity unit 342, so that the gravity unit 342 is always below the liquid level of the cleaning fluid, thereby the cleaning fluid required for cleaning can be still well supplied to the cleaning head 20 when the cleaning device is in the multi-dimensional posture, so as to realize multi-cleaning-surface and multi-angle "multi-dimensional" cleaning.

Further, the liquid supply pipe 344 is elastically configured such that a portion of the liquid supply pipe 344 extending into the fluid container 30 can be deformed by the floating of the gravity unit 342, thereby maintaining the liquid suction hole below the surface of the cleaning fluid in the fluid container 30, and achieving uninterrupted liquid supply. In the present embodiment, the liquid supply pipe 344 is a silicone hose.

The liquid supply mechanism can supply cleaning fluid to the cleaning head 20 uninterruptedly in multi-dimensional operation of the portable cleaning equipment, and improves the use convenience of the portable cleaning equipment. In addition, the gravity unit 342 can ensure that the liquid suction hole is always positioned below the liquid level of the cleaning fluid in the fluid container 30, thereby effectively ensuring smooth supply of the cleaning fluid.

According to one embodiment of the present application, as shown in fig. 16, 17 and 21, the cleaning head 20 includes a cleaning head housing 22, a cleaning brush 24 rotatably connected to the cleaning head housing 22 about an axis, and a decontamination unit 28 provided within the cleaning head housing 22, the decontamination unit 28 being configured to be capable of acting on the cleaning brush 24; the portable cleaning apparatus further comprises a dirty liquid receiving chamber 222, the dirty liquid receiving chamber 222 being arranged upstream of the dirty liquid container 40 for collecting dirty fluid 70 removed from the cleaning brush 24 by the cleaning unit 28 as a first collection area.

The fluid recovery power source of the present application is capable of recovering dirty fluid collected in the first collection area into the dirty liquid container 40, wherein the dirty liquid container 40 may be understood as the second collection area of the portable cleaning device of the present application.

Specifically, referring to fig. 18, the cleaning head 20 includes a cleaning head housing 22 and a cleaning brush 24 having a rotational axis about which the cleaning brush 24 is rotatably coupled to the cleaning head housing 22, and the portable cleaning apparatus is placed on the surface to be cleaned by the cleaning brush 24 and supported on the surface to be cleaned only by the cleaning brush 24 during cleaning of the surface to be cleaned. The operator holds the grip 12 to operate the portable cleaning apparatus, wherein the operator is standing during normal operation, and the operator can adjust the attitude of the portable cleaning apparatus relative to the surface to be cleaned to achieve multi-angle, multi-dimensional cleaning of multiple cleaning surfaces.

As shown in fig. 19 and 20, the cleaning head housing 22 includes a receiving chamber (not shown) and an opening (not shown) in fluid communication with the receiving chamber, the cleaning brush 24 being positioned in the cleaning head housing 22 for rotational movement about an axis of rotation, the opening having a longitudinal extent parallel to the axis of rotation such that a portion of the cleaning brush 24 is received in the receiving chamber through the opening. Specifically, as shown in fig. 19, the cleaning head housing 22 includes a body 225 and a holding portion 226, the receiving cavity and the opening are provided in the body 225, the holding portion 226 extends from both ends of the body 225 extending lengthwise to a side away from the opening, the cleaning brush 24 is transversely held between the holding portions 226 at both ends of the body 225, and is partially received in the receiving cavity, so that the cleaning surface of the cleaning brush 24 has an exposed area exposed to the receiving cavity and a hidden area received in the receiving cavity. Specifically, in some embodiments, the opening has a length that is greater than the length of the cleaning brush 24 and a width that is less than the diameter of the cleaning brush 24, such that the cleaning brush 24 can be partially received in the receiving chamber.

In this embodiment, a fluid loading device is further disposed in the receiving chamber of the cleaning head 20, and the fluid loading device is fixed to the cleaning head housing 22 and configured to load the cleaning fluid at least in a longitudinal direction of the cleaning brush 24.

Specifically, the fluid loading device includes a liquid spray tube 26, the liquid spray tube 26 is disposed lengthwise adjacent to the cleaning brush 24, and the cleaning brush 24 is provided with a plurality of liquid spray holes 262 at a predetermined density, as shown in fig. 18. Preferably, the longitudinal extension direction of the liquid spraying tube 26 is parallel to the rotation axis of the cleaning brush 24, and the plurality of liquid spraying holes 262 are arranged in a row at intervals along the longitudinal direction of the liquid spraying tube 26. During the rotation of the cleaning brush 24, the liquid ejecting holes 262 continuously eject the cleaning fluid to the cleaning brush 24, so that the circumferential surface of the cleaning brush 24 is wetted, thereby ensuring the cleaning effect. It should be understood that the arrangement of the liquid spraying holes 262 may be other, for example, the plurality of liquid spraying holes 262 are densely arranged on the circumferential surface of the liquid spraying tube 26, and the dense arrangement on the circumferential surface of the liquid spraying tube 26 means that the plurality of liquid spraying holes 262 are arranged in the longitudinal direction of the cleaning brush 24, and the plurality of liquid spraying holes 262 are also arranged in the circumferential direction of the cleaning brush 24. In one embodiment, the plurality of liquid ejecting holes 262 are arranged in an array on the cleaning brush 24, i.e., a plurality of rows of liquid ejecting holes 262 and a plurality of columns of liquid ejecting holes 262 are formed.

It is worth emphasizing that, since the plurality of liquid ejecting holes 262 are densely distributed on the liquid ejecting pipe 26, the size of a single liquid ejecting hole 262 is smaller than the liquid ejecting area of the liquid ejecting opening or the liquid ejecting gap in the prior art, and a sufficient liquid ejecting pressure can be provided to vertically and uniformly eject the cleaning fluid on the cleaning brush 24, so as to save the amount of the fluid on the premise of meeting the cleaning requirement. In operation, the liquid spraying holes 262 at different positions on the liquid spraying pipe 26 spray liquid vertically, so that the spraying area of the cleaning fluid sprayed onto the cleaning brush 24 is large enough under different working positions of the cleaning device, thereby ensuring that the cleaning brush 24 is uniformly wetted and realizing multi-angle and multi-dimensional cleaning of multiple cleaning surfaces.

It should also be understood that the size of the liquid ejecting hole 262 affects the liquid ejecting pressure and the liquid ejecting flow rate of the cleaning fluid, and since the capacity of the fluid tank 30 and the flow rate of the liquid supply pump 32 of the portable cleaning apparatus are small, the size of the liquid ejecting hole 262 and the liquid ejecting flow rate should satisfy a certain relationship in order to satisfy the liquid ejecting pressure and the liquid ejecting flow rate under the cleaning effect. Although not wishing to be bound by theory, the inventors of the present application have found that the diameter of the liquid ejecting hole 262 is 0.15 mm to 0.5 mm, and the flow rate of the liquid ejecting hole 262 is 60 ml/min to 90 ml/min, so that the cleaning effect is better while the "multi-dimensional" cleaning is ensured.

As shown in fig. 21 and 22, a dirty liquid accommodating chamber 222 for accommodating dirty fluid and a dirty liquid outlet 224 communicating with the dirty liquid accommodating chamber 222 are provided in the cleaning head housing 22, the dirty liquid accommodating chamber 222 communicates with the accommodating chamber, and the dirty fluid 70 generated by the cleaning brush 24 cleaning the surface to be cleaned can be delivered to the dirty liquid container 40 through the dirty liquid outlet 224. Specifically, the dirty liquid holding chamber 222 has an open end 220 adjacent to the cleaning brush 24, a closed end 221 disposed opposite to the open end 220, and a connecting wall 223 connecting the open end 220 and the closed end 221. In one embodiment, the contaminated liquid outlet 224 may be provided at the closed end 221, and in another embodiment, the contaminated liquid outlet 224 may be provided at the connecting wall 223, which is not limited herein.

The cleaning head 20 further comprises a dirt removal unit 28 for scraping off the dirty fluid 70, the dirt removal unit 28 being configured to act on the cleaning brush 24 to cause the dirty fluid 70 (in particular water containing dirt particles) carried by the cleaning brush 24 to fall off and be delivered towards the open end 220 of the dirty liquid receiving chamber 222 to deliver the dirty fluid 70 from the dirty liquid receiving chamber 222 to the dirty liquid container 40 for collection. Specifically, the soil removal unit 28 is located in the aforementioned housing chamber and disposed adjacent to the cleaning brush 24 and the soil solution housing chamber 222, and is disposed between the liquid supply mechanism and the soil solution housing chamber 222, and the soil removal unit 28 includes one or more members protruding into the coating (bristles) of the cleaning brush 24 to a predetermined depth, which are configured to be rounded or chamfered toward the circumferential surface of the cleaning brush 24, so as to be able to guide the dirty fluid 70 to the open end 220 of the soil solution housing chamber 222. It should be noted that the predetermined depth should be less than the thickness of the covering of the cleaning brush 24.

Further, the lengthwise extension direction of the open end 220 of the dirty liquid receiving cavity 222 is parallel to the rotation axis of the cleaning brush 24, which facilitates the dirt removing unit 28 to guide the dirty fluid 70 to the open end 220 of the dirty liquid receiving cavity 222.

According to an embodiment of the present application, the dirty liquid accommodating chamber 222 is provided with dirty liquid outlet 224 for recovering the fluid in the dirty liquid accommodating chamber 222 at each of two ends in the length direction thereof, the cleaning head 20 has a first usage posture in which one end of the dirty liquid accommodating chamber 222 is at a raised position in the gravity direction with respect to the other end thereof, and the dirty liquid outlet 224 at the other end away from the raised position of the dirty liquid accommodating chamber 222 is configured to communicate with the fluid recovery power source in the first usage posture.

Specifically, the contaminated liquid outlet 224 is a first contaminated liquid outlet 2241 and a second contaminated liquid outlet 2242. The fluid recovery mechanism can recover the dirty fluid 70 received in the dirty fluid storage chamber 222 through the first dirty fluid outlet 2241 and/or the second dirty fluid outlet 2242. Preferably, the number of the first contaminated liquid outlet 2241 and the second contaminated liquid outlet 2242 is one. Of course, the number of the first contaminated liquid outlet 2241 and the second contaminated liquid outlet 2242 may be plural.

In the present embodiment, the positions of the first contaminated liquid outlet 2241 and the second contaminated liquid outlet 2242 are each arranged to be offset from the center line of the contaminated liquid accommodating chamber 222. Specifically, the first contaminated liquid outlet 2241 and the second contaminated liquid outlet 2242 are located at positions deviated from the center line of the length of the contaminated liquid holding chamber 222 toward both ends by a predetermined distance, and the predetermined distance is configured to be 1/4 or more of the length of the contaminated liquid holding chamber 222. Here, the center line is understood to be located substantially at the middle of the dirty liquid storage chamber 222 in the longitudinal direction (X direction). The centerline is perpendicular to the rotational axis of the cleaning brush 24. Optionally, the first and second effluent outlets 2241 and 2242 are substantially symmetrical about a centerline.

Further, as shown in fig. 10, 23, 25 and 39, the dirty fluid 70 in the dirty fluid receiving chamber 222 is recovered to the dirty fluid tank 40 through the first return branch 232 and the second return branch 233. Wherein the first return branch 232 and the second return branch 233 each comprise an inlet end extending into the dirty liquid holding chamber 222 for dirty fluid absorption.

In a possible embodiment, as shown in fig. 39, the two ends of the contaminated fluid accommodating chamber 222 along the length direction thereof are provided with a first contaminated fluid outlet 2241 and a second contaminated fluid outlet 2242, and the first contaminated fluid outlet 2241 and the second contaminated fluid outlet 2242 are configured to be formed by the inlet ends 230 of the first return branch 232 and the second return branch 233. Specifically, at least a portion of the first and second return branches 232, 233 extends into the dirty liquid accommodating chamber 222, and the inlet ends 230 of the two return branches are fixed to the opposite ends of the dirty liquid accommodating chamber 222.

Alternatively, in one embodiment, as shown in fig. 26 and 27, the first and second contaminated liquid outlet ports 2241 and 2242 are formed directly from the self-structure configuration of the contaminated liquid accommodating chamber 222. Specifically, the contaminated liquid housing chamber 222 includes a body that collects the dirty fluid generated by the cleaning brush 24, and the first contaminated liquid outlet 2241 and the second contaminated liquid outlet 2242 are configured as through holes formed through the body at both ends of the contaminated liquid housing chamber 222, and the fluid recovery mechanism connection through hole sucks out the dirty fluid 70.

As shown in fig. 1, 3 and 5, the portable cleaning apparatus has a first posture in use in which one end of the dirty liquid accommodating chamber 222 is in a raised position with respect to the other end thereof in the direction of gravity, and a second posture in use in which the dirty liquid outlet 224 at both ends of the dirty liquid accommodating chamber 222 is substantially on the same horizontal plane. In the first usage posture, the dirty liquid outlet 224 at one end of the raised position of the dirty liquid holding chamber 222 is configured to communicate with the fluid recovery power source. The portable washing apparatus is provided with a dirty liquid outlet 224 at one end of the dirty liquid receiving chamber 222 in each of the first and second usage postures, and is configured to allow dirty fluid generated by the cleaning brush 24 to flow therethrough. The same horizontal plane can be understood as the distance between the dirty liquid outlet 224 at both ends and the horizontal ground is the same.

As shown in fig. 23, in a possible embodiment, the fluid recovery power source comprises a drain pump 52 capable of enabling dirty fluid 70 to flow therethrough and be sucked into the dirty fluid container 40, the drain pump 52 is one, an inlet of the drain pump 52 is connected to at least one end of the dirty fluid outlet capable of being connected to both ends, and an outlet of the drain pump 52 is connected to the dirty fluid container 40.

Specifically, a liquid inlet of the drain pump 52 is communicated with the first contaminated liquid outlet 2241 and/or the second contaminated liquid outlet 2242 through a pipeline, and a liquid outlet of the drain pump 52 is communicated with the contaminated liquid container 40 through a pipeline.

In this embodiment, the positive displacement pump 52 is a peristaltic pump or a diaphragm pump. It can be understood that the diaphragm pump utilizes the reciprocating motion of the diaphragm to change the volume of the cavity in the diaphragm pump, thereby changing the water pressure in the cavity in the diaphragm pump, and the diaphragm pump has unidirectionality and can prevent the backflow of dirty fluid. For example, the diaphragm pump includes a motor and an eccentric, the motor drives the eccentric to rotate, one end of a bearing abuts against the edge of the eccentric, and the other end of the bearing abuts against a side surface of the diaphragm, so that the eccentric drives the diaphragm to reciprocate through the bearing, thereby changing the volume and water pressure of a cavity defined by the diaphragm. The diaphragm pump has the advantages that the diaphragm can be made of neoprene, fluororubber or nitrile rubber and the like, so that the diaphragm pump has better corrosion resistance, is simpler in structure and smaller in size compared with a traditional plunger pump, and further has the effect of improving the portability of portable cleaning equipment.

In another possible embodiment, as shown in fig. 24 and 25, the fluid recycling power source comprises an air pump 544 or a fan 542 which can draw the dirty fluid 70 into the dirty fluid container 40 through a recycling line that can communicate with at least one of the two dirty fluid outlets.

Specifically, the fluid recovery power source is a negative pressure generating device that generates a negative pressure environment in the dirty liquid container 40 by sucking the gas in the dirty liquid container 40, and allows the dirty fluid 70 to be sucked out of the dirty liquid container 40. In such embodiments, the negative pressure producing device is located downstream of the dirty liquid container 40 in the direction of flow of the dirty fluid, and the dirty fluid 70 does not flow through the negative pressure producing device, but rather enters the dirty liquid container 40 directly.

It should be appreciated that, since the dirty fluid 70 outputted from the dirty fluid outlet 224 does not need to pass through the air pump 544 or the blower 542, the air pump 544 or the blower 542 is mainly designed to generate a vacuum environment, and is not required to have better corrosion resistance, and as an alternative embodiment, the air pump 544 may be a diaphragm pump, a plunger pump, a peristaltic pump or an electromagnetic pump.

Wherein the diaphragm pump fails in order to prevent dirty fluid from entering the diaphragm pump. A filter device (not shown) may be added upstream of the diaphragm pump, and specifically, the filter device is disposed on the contaminated liquid container 40.

In this embodiment, although there is no problem that the suction of the dirty fluid in the lower dirty liquid outlet is more difficult than the suction of the dirty fluid in the upper dirty liquid outlet, the inventors of the present application have found that the negative pressure environment in the dirty liquid container 40 is affected if the air is continuously sucked in the upper dirty liquid outlet, and the dirty fluid suction efficiency in the lower dirty liquid outlet cannot be further improved.

Specifically, the fluid recovery power source includes two air exhaust floating balls and two balancing weights.

So, dirty fluid suction of the chamber that two foul solution delivery outlets 224 correspond does not influence each other, avoids a foul solution delivery outlet to draw air influence negative pressure environment.

As shown in fig. 37, in the present application, the dirty liquid holding chamber 222 has an open end for receiving the dirty liquid 70, and a closed end 221 disposed opposite to the open end 220, wherein the closed end 221 has a first guide surface 126 and a second guide surface 127; the distance between the side of the first flow guiding surface 126 connected with the second flow guiding surface 127 and the open end 220 is smaller than the distance between the side of the first flow guiding surface 126 far away from the second flow guiding surface 127 and the open end 220.

To further facilitate the dirty fluid to flow to the dirty fluid outlet for discharge, in some embodiments, the closed end 221 of the dirty fluid accommodating cavity 222 has a first guiding surface 126 and a second guiding surface 127 connected to each other at opposite sides, and the side where the first guiding surface 126 and the second guiding surface 127 are connected to each other is closer to the open end 220 than the side where the first guiding surface 126 and the second guiding surface 127 are far away from each other, that is, the closed end 221 of the dirty fluid accommodating cavity 222 is "high in the middle" and "low on both sides", and the two dirty fluid outlets 224 are used for respectively outputting the dirty fluid guided by the first guiding surface 126 and the second guiding surface 127.

In this way, in the "multi-dimensional" cleaning process, the cleaning apparatus is switched between different postures, and the two dirty liquid output ports 224 are located downstream of the first flow guiding surface 126 and the second flow guiding surface 127, which is beneficial to the fluid recovery of dirty fluid when the portable cleaning apparatus is in different postures.

Further, the air in the dirty liquid container 40 can communicate with the dirty liquid accommodating cavity 222 through a negative pressure exhaust pipeline, and a connection point of the negative pressure exhaust pipeline connecting the dirty liquid accommodating cavity 222 is located at a junction of the first flow guiding surface 126 and the second flow guiding surface 127.

On the other hand, the exhaust duct 66 may contain a small amount of dirty fluid in the exhaust gas, and the small amount of dirty fluid can be newly output to the dirty fluid accommodating chamber 222 through the exhaust duct 66 to perform "secondary recovery", so that the recovery efficiency of the dirty fluid is improved, and the dirty fluid is not leaked. On the other hand, during the exhaust process of the exhaust duct 66, the dirty fluid entering the dirty fluid accommodating chamber 222 is disturbed to both sides by the airflow, so that the recovery efficiency of the dirty fluid is further improved, which can achieve three purposes.
