detailed description

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

Referring to FIG. 1 , it is a schematic diagram of the overall structure of a washing and cleaning device of the present invention. Washing and cleaning equipment of the present invention comprises:

The scrubbing mechanism 10 is used to clean the cleaning surface. The scrubbing mechanism 10 is provided with a cleaning shell 11 to fix the components; the chassis of the cleaning shell 11 is provided with a scrubbing piece. The scrubbing member is any structure capable of scrubbing the cleaning surface, for example, it may be a rolling brush structure in the prior art, or it may be a brush plate structure. In this embodiment, the brush plate 12 is used as an example for the scrubbing piece. Specifically, as shown in FIG. Extend along the middle part of the brush plate 12 to the edge with a helical line. The brush plate 12 rotates and rubs against the cleaning surface to clean the cleaning surface. A miniature clean water tank 13 is installed on the cleaning shell 11 , and the miniature clean water tank 13 can be installed on the inside of the cleaning shell 11 , or on the outside of the cleaning shell 11 . The miniature clean water tank 13 is connected with several nozzles 14 pointing to the scrubbing piece and/or its surroundings. When the scrubbing piece is a brush plate 12, the nozzles 14 point to the brush plate 12, and can also point to the surroundings of the brush plate 12. When the scrubbing part is a rolling brush, the nozzle can point to the surrounding of the rolling brush. In this embodiment, the spray head 14 sprays the cleaning liquid in the miniature clean water tank to the brush plate 12, and the brush plate 12 exerts a better cleaning effect under the action of the cleaning liquid. The cleaning liquid becomes sewage after cleaning the cleaning surface, and the sewage on the cleaning surface needs to be sucked away to realize the cleaning of the cleaning surface, so a suction port is arranged in or around the cleaning piece. In this embodiment, the helical bristles, brush pieces or brush strips can gather the sewage at the position corresponding to the middle of the brush tray 12 , so a suction port 15 is provided in the corresponding middle of the brush tray 12 . When the scrubbing part is a rolling brush, the suction port 15 can be arranged around the rolling brush. The suction port 15 is located at one end of the suction channel, and the other end of the suction channel is connected to a sewage collection tank 16 , and an impeller 17 is arranged in the sewage collection tank 16 . The impeller 17 rotates to generate centrifugal force to suck the sewage into the sewage collection tank 16. At the same time, the blades of the impeller 17 produce radial thrust on the sewage, pushing the sewage to the edge of the sewage collection tank 16. The outlet of the sewage collection tank 16 is connected to a micro sewage tank 18 to hold the inhaled sewage.

The water storage mechanism 20, as shown in FIG. The first sewage pipe 24 is connected to the water supplement 27 and the drain 28, and the second end of the bidirectional pump 22 is connected to the miniature clean water tank 13 and the miniature sewage tank 18 through the second clean water pipe 25 and the second sewage pipe 26 respectively, The communication between the miniature clean water tank 13 and the two-way pump 22 and the water supply part 27, and the communication between the micro sewage tank 18 and the two-way pump 22 and the drainage part 28 are realized. With reference to Fig. 4 and shown in Fig. 5, in order to guarantee work, clean water can only flow to miniature clean water tank 13 from replenishment part 27, and sewage can only gather to drainage part 28 from miniature dirty water tank 18, described first clean water pipe 23, The second clean water pipe 25, the first sewage pipe 24 and the second sewage pipe 26 are all connected with a one-way valve 29, and the clean water is unidirectionally connected along the direction of the water supply part 27, the bidirectional pump 22 and the miniature clean water tank 13, and the sewage is connected along the direction of the micro clean water tank 13. The mini sewage tank 18, the two-way pump 22 and the drainage member 28 are connected in one direction. With reference to shown in Figure 4, when the motor of two-way pump 22 rotates forwards, clear water enters two-way pump 22 from bottom to top through the first clear water pipe 23 that communicates with replenishing parts 27, is pumped into miniature clean water tank 13 through second clear water pipe 25 and realizes replenishing water. Because of the existence of the check valve 29, the first sewage pipe 24 between the drain member 28 and the two-way pump 22 is closed, and the second sewage pipe 26 between the two-way pump 22 and the miniature sewage tank 18 is closed, so the sewage does not Will enter the two-way pump 22 from the drainage member 28, and the water pumped out by the two-way pump 22 will not enter the micro-sewage tank 18 from the second sewage pipe 26 to occupy the capacity of the micro-sewage tank 18, and cause clean water to mix with sewage. In Fig. 5, when the motor of the two-way pump 22 is reversed, the sewage enters the two-way pump 22 from the micro sewage tank 18 from top to bottom through the second sewage pipe 26, and then is pumped into the drainage member by the two-way pump 22 through the first sewage pipe 24. 28 to discharge sewage. Because of the existence of check valve 29, the first clean water pipe 23 and the second clean water pipe 25 between the miniature clean water tank 13 and the large-capacity clean water tank and the two-way pump 22 are closed, and now the clear water in the miniature clean water tank 13 will not It is pumped out, and the sewage pumped out from the mini sewage tank 18 also can not enter the large-capacity clean water tank and cause the pollution of clear water. Because of the existence of the miniature clean water tank 13 and the miniature sewage tank 18, the replenishment of clear water and the discharge of sewage all work at intervals, so the forward and reverse rotation of the motor of the bidirectional pump 22 can be controlled manually or automatically by the switch to supplement clear water or Discharge of sewage will not cause no clean water or untimely discharge of sewage during cleaning. Further, the one-way valve through which the clean water flows can adopt various common miniature one-way valves, while the one-way valve through which the sewage flows can adopt a miniature duckbill valve which is more suitable for particles to flow through.

Referring to FIG. 1 , for the convenience of cleaning, the present invention also includes a handle bar 30 , one end of which is hinged to the cleaning shell 11 , so that the relative angle between the handle bar 30 and the scrubbing mechanism 10 can be adjusted conveniently. The other end of the hand-held rod 30 is connected to the box body 21 through a hose 31, so that the scrubbing mechanism 10 is movable, and can be lifted up to clean the high place of the wall facade, and can also be obliquely downward to clean the low place of the wall facade or tow it. land. The second clean water pipe 25 and the second sewage pipe 26 are located in the handle bar 30 , and the handle bar 30 forms protection for the second clean water pipe 25 and the second sewage pipe 26 .

In the present invention, a miniature clean water tank 13 is arranged in the scrubbing mechanism 10, so that a part of clean water can be buffered as close as possible to the cleaning surface. Because the distance between this part of clean water and the cleaning surface is constant, no matter whether the scrubbing mechanism 10 is cleaning a low position or a high place, the flow of clean water flowing out from the miniature clean water tank 13 is almost unchanged, so there is no need to adjust the rotating speed of the two-way pump 22, simplifying The control of the bidirectional pump 22 is achieved, and the setting of the speed control switch is avoided at the same time. In the case of fewer components, the structure of the cleaning device is simpler, easier to assemble, and lower in cost. Simultaneously, because the displacement of bidirectional pump 22 does not need to be changed, therefore in the embodiment of the present invention, bidirectional pump 22 can be selected as the gear pump with simple and compact structure, small volume, light weight, cheap price, easy maintenance and reliable operation. Choose other pumps that can achieve bidirectional pumping, such as peristaltic pumps or Roots pumps.

In the embodiment of the present invention, in order to facilitate use in various situations, the water supply component 27 and the drainage component 28 are respectively set as a large-capacity clean water tank and a large-capacity dirty water tank. By setting a large-capacity clean water tank, you can choose to add detergent or disinfectant. When working, press the clean water in the large-capacity clean water tank into the miniature clean water tank 13, and pump the sewage in the micro-sewage tank 18 into the large-capacity sewage tank. , The collection of sewage through the large-capacity sewage tank facilitates the discharge of sewage after treatment and prevents pollution of the environment. After the large-capacity clear water tank is evacuated or the large-capacity sewage tank is filled, it can be stopped for processing. The large-capacity clean water tank and the large-capacity sewage tank are arranged in the box body 21. At this time, the box body 21 is heavy, so wheels can be installed at the bottom of the box body 21, and the box body 21 can be moved by hand or electric means to match different cleaning position. Handle, fixed or telescopic push-pull rod can also be set on the box body (concrete structure is the same as the trolley box in the prior art, no more details are given here), thereby being convenient to move.

In other embodiments of the present invention, the water replenishing member 27 can also be directly set as a clean water input pipe, and the clean water input pipe is directly connected to a tap water valve to facilitate water replenishment. Of course, in order to add detergent or disinfectant, the water replenishing part 27 can be a large-capacity clean water tank connected to the clean water input pipe, and the tap water valve is opened, and the clean water enters the large-capacity clean water tank through the clean water input pipe to mix with detergent or disinfectant, thereby being able to Better cleansing surfaces. At this time, the drainage member 28 is set as a large-capacity drainage tank, and the sewage containing detergent or disinfectant is collected uniformly. The large-capacity sewage tank can be used to hold sediment and add adsorption or decontamination materials to filter the sewage, so that the water source can be used. reuse. In other embodiments of the present invention, the drain member 28 can also be directly set as a drain pipe, and the cleaned sewage is directly discharged through the drain pipe without being buffered by a large-capacity sewage tank. Under the situation that only clean water input pipes are set or no detergent is added in the large-capacity clean water tank, the sewage can be directly discharged into the sewer through the drainpipe or directly discharged in the field. In order to extract all the clean water in the large-capacity clean water tank as much as possible, the first clean water pipe 23 is inserted into the bottom of the large-capacity clean water tank, and the bottom surface of the large-capacity clean water tank is inclined, so that the bottom surface of one side of the large-capacity clean water tank is low in height. When remaining a small amount of clear water, a small amount of clear water can be gathered here, and the first clear water pipe 23 is set corresponding to the lowest point of the bottom surface of the large-capacity clean water tank, thereby the clear water gathered here can also be extracted out.

Referring to Fig. 3, since the two ends of the two-way pump 22 are respectively connected to two water pipes, and each water pipe is connected with a one-way valve 29, for the convenience of the connection of each part, the two ends of the two-way pump 22 described in this embodiment are connected to each other. It is connected to each water pipe through a three-way joint, and the one-way valve 29 is arranged between the three-way joint and each water pipe. On the one hand, there is no need to set another connection position; on the other hand, the one-way valve 29 is set close to the two-way pump 22, that is, the one-way water pipe is closed at a position close to the port of the two-way pump 22, so that when the two-way pump 22 is working, it will not be sucked to the closed position. The residual liquid in the water pipe along the way avoids the mixing of clean water and sewage and improves the cleaning effect.

Further, as shown in Fig. 2 and Fig. 6, since the scrubbing mechanism 10 has a variety of different working conditions such as cleaning low positions or high places, in order to ensure that under various working conditions, clean water can flow from the miniature clean water tank 13 to the washing machine to be cleaned. On the washing face, the miniature clean water tank 13 is arranged near the top of the cleaning shell 11, and the miniature clean water tank 13 is located in the range of nine o'clock-twelve o'clock-three o'clock of the cleaning shell 11, the The miniature sewage tank 18 is arranged close to the chassis, and the miniature sewage tank 18 is located within the range of three o'clock-six o'clock-nine o'clock of the cleaning shell 11 . Wherein, when cleaning the ground with the scrubbing mechanism 10, its front is the twelve o'clock direction, and what time-what time is the clockwise direction. That is, the miniature clean water tank 13 is not only positioned near the top of the cleaning case 11, but also arranged near the front portion of the cleaning case 11, and the miniature dirty water tank 18 is not only positioned near the bottom of the cleaning case 11, but also arranged near the rear of the cleaning case 11. At this time, when cleaning the low position, the miniature clean water tank 13 is positioned above the surface to be cleaned, and its height is higher than the miniature sewage tank 18, and the clean water can flow to the surface to be cleaned below due to gravity, and can be smoothly sucked into the micro sewage Inside box 18. When cleaning high places, the miniature clean water tank 13 is still on the top of the scrubbing mechanism 10, and the miniature dirty water tank 18 is positioned at the bottom of the scrubbing mechanism 10. Out, the brush plate 12 uses clear water to clean the cleaning surface, and the cleaned sewage is sucked into the sewage tank below, which conforms to the natural law of water flowing from a high place to a low place. Further, the sewage inlet of the miniature sewage tank 18 is located at the highest point of the miniature sewage tank 18, which is the shortest distance from the three o'clock to nine o'clock connection and is the sewage tank farthest away from the wall. The outlet 131 is positioned at the lowest part of the miniature clean water tank 13, which is the shortest and the closest to the wall from three o'clock to nine o'clock.

Further, in order to ensure that the scrubbing mechanism 10 is in a state parallel to the ground or in a state perpendicular to the ground, the clean water outlet 131 of the miniature clean water tank 13, the sewage collection port 161 of the sewage collection tank 16 or the sewage of the miniature sewage tank 18 The outlets 181 are all located at the lowest point of the corresponding water tank, the gap between the clean water outlet 131 of the miniature clean water tank 13, the sewage collection port 161 of the sewage collection tank 16 and the corresponding two sides of the sewage outlet 181 of the miniature sewage tank 18 The corners are acute. Due to the setting of the acute angle, the position corresponding to the water outlet on one side of the miniature clean water tank 13, the sewage collection tank 16 and the miniature sewage tank 18 near the chassis of the cleaning shell 11 is inclined to the chassis direction of the cleaning shell 11, and corresponds to a side of the six o'clock direction. The side is inclined from the top of the cleaning shell 11 to the chassis along the direction of twelve o'clock to six o'clock. Thereby, the position where the two sides intersect is at the lowest point of the corresponding water tank when the scrubbing mechanism 10 is attached to the ground, and is still at the lowest point of the corresponding water tank when the scrubbing mechanism 10 is attached to the wall facade, thereby ensuring that the water flow in the water tank can be completely from The water outlet provided there flows out. Further, the number of scrubbing parts can be one or more as needed, and in this embodiment, there are two brush trays 12 . The two brush plates 12 are each provided with a vertically upward suction channel, and an impeller 17 is respectively arranged above the suction channel. Compared with two brush plates sharing one impeller 17, the arrangement of the double impeller 17 is more efficient. In this way, each Each of the brush plates 12 is provided with a corresponding sewage collection tank 16 , and both sewage collection tanks 16 can be connected to a micro sewage tank 18 .

As a preferred embodiment of the present invention, the third clean water pipe 19 connecting the clean water outlet 131 of the miniature clean water tank 13 and the spray head 14 is arranged obliquely. Because the miniature clean water tank 13 is small in volume, so the water pressure from the clean water outlet 131 to the shower nozzle 14 is relatively small, when the water level in the miniature clean water tank 13 is very low, if cavitation can not be discharged immediately in the third clean water pipe 19, it will hinder the thinner water. The flow of water in the 3rd clean water pipe 19, certainly the 3rd clean water pipe 19 also can adopt thicker water pipe, less water outlet; Perhaps a water pump is installed on the 3rd clean water pipe.

The two-way pump 22 irregularly draws clear water into the miniature clean water tank 13, and sewage is extracted from the miniature sewage tank 18, and judges whether need replenishment or pumping by the water level detection assembly of the height of the liquid level in the detection tank. Such as the entrance of miniature clean water tank 13, miniature sewage tank 18 and the outlet of miniature clean water tank 13, miniature sewage tank 18 each a conductive probe, there is also an electrode in miniature clean water tank 13, miniature sewage tank 18, conductive probe and The electrodes are connected, and according to the change of the resistance of the two conductive probes, it is determined whether there is liquid at the two conductive probes. Or a magnetic float is set in the miniature clean water tank 13 and the miniature dirty water tank 18, and a magnetic detection element, such as a Hall element, is set at the inlet and outlet of the miniature clean water tank 13 and the miniature dirty water tank 18. Of course, other methods for detecting the liquid level are also available. When starting to work, the two-way pump 22 first pumped clear water into the miniature clean water tank 13, and when the upper miniature sewage tank 18 liquid level was high, the two-way pump 22 pumped water from the miniature sewage tank 18 to the large-capacity sewage tank, so as to drain the water in the miniature sewage tank 18 as much as possible. Sewage is evacuated. Because a certain amount of clear water is buffered in the miniature clean water tank 13, when the miniature sewage tank 18 is sucked, the cleaning work can still be carried out, and the impeller 17 continues to pump the cleaned sewage into the miniature sewage tank 18, so in the working process , the two-way pump 22 does not necessarily need to completely evacuate the sewage in the micro-sewage tank 18, and the space for pumping water is reserved for the micro-sewage tank 18. When the sewage in the miniature sewage tank 18 is reduced to a certain water level, or the clear water in the miniature clean water tank 13 is low to a certain water level, then the two-way pump 22 reverses, and the clear water in the large-capacity clean water tank is pressed into the miniature clean water tank 13, for Miniature clean water tank 13 replenishes water.

In one embodiment of the present invention, the second clean water pipe 25 and the second sewage pipe 26 are arranged in the handle bar 30. In order to avoid the position of the impeller 17, the handle bar 30 is connected with the cleaning shell 11 through the first rotating shaft 32, and the first The rotating shaft 32 is an arc-shaped rod, and the two ends of the arc-shaped rod are rotationally connected with the cleaning shell 11 along the direction of the nine o'clock and three o'clock lines, and the middle part of the first rotating shaft 32 is provided with a second rotating shaft 33 , the axial direction of the second rotating shaft 33 is perpendicular to the first rotating shaft 32 . The first rotating shaft 32 is used to adjust the horizontal angle between the bottom surface of the scrubbing mechanism 10 and the handle bar 30. If the scrubbing mechanism 10 is horizontally facing down and the handle bar 30 is vertically upward as the initial position, the operator stands behind the handle bar 30. A rotating shaft 32 can adjust the front and back distance of the scrubbing mechanism 10 from the operator, so that when the operator moves the scrubbing mechanism 10 back and forth, the scrubbing mechanism 10 can always be kept horizontally attached to the ground. And the second rotating shaft 33 is in order to adjust the left and right distance of the scrubbing mechanism 10 from the operator, so that when the operator moves the scrubbing mechanism 10 left and right, keep the scrubbing mechanism 10 horizontally attached to the ground. The above-mentioned first and second rotating shafts 33 are rotatable shafts or shafts that are rotated around. In other embodiments of the present invention, the connection between the handle bar 30 and the scrubbing mechanism 10 can also be provided with a ball joint like the existing mop. The advantage of the ball joint is that the handle bar 30 can three-dimensionally adjust the operating angle of the brush tray . The first rotating shaft 32 or the ball joint is not necessarily arranged at the centerline or the center of the brush tray, because the rotation of the brush tray has a torsion force biased in one direction, and partial torsion force can be offset by offsetting from the center line or the center. Certainly, the setting method of the rotating part of the handle bar 30 can refer to the existing mop, and other ways of adjusting the handle bar 30 are also applicable in the present invention.

Further, part of the handle bar 30, specifically, an additional bar is detachably connected to the end of the handle bar 30 close to the water storage mechanism 20, and the additional bar is a handle extending radially outward along the handle bar 30. , so that the additional rod can be held indoors, and the hand-held rod 30 is partially stretched out of the window to scrub the glass outside the window. In this embodiment, a socket can be provided on the handle bar 30, or an additional sleeve can be arranged side by side, so that the handle can be inserted into the socket or the additional sleeve, and the handle can be set in an "L" or "U" shape. , form " h " shape bar with hand-held bar 30, hold " L " or " U " shape bar part, hand-held bar 30 parts are stretched out the window, can scrub the glass outside the window in the window.

Apparently, the above-mentioned embodiments are only examples for clear description, and are not intended to limit the implementation. For those of ordinary skill in the art, on the basis of the above description, other changes or changes in various forms can also be made. It is not necessary and impossible to exhaustively list all the implementation manners here.
