In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will recognize without departing from the spirit and scope of the present invention.
As shown in fig. 1 to 4, the present application provides a water tank pressure relief system for a self-moving robot, and particularly relates to a water replenishing scheme for a sweeping robot. Wherein, water tank pressure relief system from mobile robot includes: water filling device 10, self-moving robot 20, pump 30 and pressure relief device.
The watering apparatus 10 may be a base station, a faucet, or the like. In this embodiment, the water adding device 10 employs a base station, which can be used as a supply and service base for the self-moving robot 20 and can provide services such as water supplement, charging, cleaning, pollution discharge, dirt collection, disinfection, and the like for the self-moving robot 20. The water adding device 10 is specifically used to replenish clean water for the self-moving robot 20 as in the present embodiment. The self-moving robot 20 may be a sweeper.
The self-moving robot 20 is configured to be mobile, i.e., freely movable on the floor of the cleaning site to accomplish a large area cleaning task. In order to meet higher cleaning requirements, the self-moving robot 20 is equipped with a mopping assembly for mopping the floor in addition to the basic dust sweeping and collecting functions, thereby improving the cleaning effect. Be provided with clear water tank 21 on mobile robot 20, clear water tank 21 can supply with clear water for the subassembly that drags and wash to satisfy the subassembly that drags and wash and realize the function needs of dragging and washing.
In addition, a water replenishing container 11 is arranged on the water replenishing device 10; when the self-moving robot 20 returns to the water adding device 10, the clean water tank 21 can be communicated with the water supplementing container 11; the pump 30 is communicated with the clean water tank 21 and is used for enabling a negative pressure state to be formed in the clean water tank 21; the pressure relief device is communicated with the clean water tank 21 and is used for guiding air in the external environment into the clean water tank 21. The pump 30 may be disposed on the watering device 10 or the self-moving robot 20 according to the needs.
In summary, the implementation of the technical solution of the present embodiment has the following beneficial effects: when the water tank pressure relief system of the self-moving robot works, the self-moving robot 20 returns to the water adding device 10 due to water shortage, the water supplementing container 11 is communicated with the clear water tank 21, meanwhile, the pump 30 starts to pump air in the clear water tank 21, so that a negative pressure state is formed in the clear water tank 21, and water in the water supplementing container 11 can be injected into the clear water tank 21 to achieve the purpose of supplementing water. When the pump 30 stops pumping air, although the inside of the clean water tank 21 still maintains a negative pressure state and is lower than the external atmospheric pressure, the pressure relief device is opened to enable the air in the external environment to flow into the clean water tank 21, so that the internal and external air pressures of the clean water tank 21 can be restored to be balanced, the self-moving robot 20 can be normally separated from the water adding device 10, the shaking problem can not occur when the self-moving robot 20 is separated from the water adding device 10, and the normal work and stability of the self-moving robot 20 can be ensured.
It can be understood that before the clear water tank 21 is replenished, the clear water tank 21 needs to be pumped to form negative pressure, so as to reduce the resistance of the clear water flowing into the clear water tank 21, thereby completing the replenishment more quickly, which is more beneficial to reducing the time consumed by the replenishment and improving the working efficiency of the self-moving robot 20.
In one embodiment, the pump 30 is disposed on the self-moving robot 20, the pump 30 is communicated with the clean water tank 21 through an air suction pipeline, and the pressure relief device is disposed in the air suction pipeline. After the mobile robot 20 returns to the base station, the pump can pump the clear water tank 21 through the air pumping pipeline to form a negative pressure state, so that water can be conveniently added; after the water is added, the pressure relief device is opened to introduce the air in the external environment into the clean water tank 21, so that the negative pressure state of the clean water tank 21 is eliminated, and the self-moving robot 20 can smoothly leave the base station.
Alternatively, as an alternative to the above embodiment, the pump 30 may be disposed on the water adding device 10, one end of the pump 30 is communicated with the water adding container 11, the other end of the pump 30 is communicated with the clean water tank 21 through an air hole on a base of the water adding device 10, and the pressure relief device is disposed on a pipeline connecting the water adding container 11 and the clean water tank 21. The technical effect the same as that of the above embodiment can be achieved by the scheme of the embodiment, the difference lies in that the pump 30 is simultaneously connected with the water replenishing container 11 and the clear water tank 21, the clear water tank 21 can be pumped before being replenished with water, when the clear water tank 21 is replenished with water, the pump 30 can also pump the excess water in the clear water tank 21 back to the water replenishing container 11, so that the clear water tank 21 can be replenished with water, a water fullness detection device or manual observation is not required to be arranged, and the automation and intelligence level of the equipment is improved.
Or, as an alternative to the above embodiment, the water replenishing container 11, the water hole on the base of the water replenishing device 10 and the clean water tank 21 are communicated through a pipeline, and a pressure relief device is arranged on the pipeline. The technical effect basically the same as that of the above embodiment can be obtained by the present solution, that is, the clear water tank 21 can be ensured to smoothly leave the base station while the clear water tank 21 is ensured to be automatically filled with water.
The technical solution of the present application is further specifically described below. In practice, there are various technical means available for eliminating the negative pressure state in the clean water tank 21. For example, in some embodiments, the pressure relief device is provided as an air valve, and the clean water tank 21 is provided with an air hole, and the air valve is provided at the air hole, and the air valve can open the air hole to introduce air in the external environment into the clean water tank 21.
Optionally, the air valve adopts an electromagnetic valve, automatic closing and opening switching actions can be realized through electric control, the work is reliable, and the response speed is high. Of course, in other embodiments, the gas valve may be a manual valve that is manually opened or closed by a user.
In addition, as an alternative of the above embodiment, the water replenishing container 11 is communicated with the clean water tank 21 through a water replenishing pipeline, and the pressure relief device is a two-position three-way electromagnetic valve which is arranged in the water replenishing pipeline. The two-position three-way electromagnetic valve is provided with a first path and a second path, the first path is used for communicating the water supplementing container 11 with the clean water tank 21, and when the first path is opened, water in the water supplementing container 11 flows into the clean water tank 21; when the second path is opened, air in the external environment flows into the clean water tank 21.
Thus, only one two-position three-way electromagnetic valve is arranged in the water replenishing pipeline, and by controlling the opening or closing of the first pipeline and the second pipeline, the clean water in the water replenishing container 11 can be flexibly controlled to flow into the clean water tank 21 to realize water replenishing, and air flows into the clean water tank 21, so that the internal and external air pressures of the clean water tank 21 are balanced, and the self-moving robot 20 is ensured to smoothly and stably leave the water replenishing device 10.
Or, in still other embodiments, the pump 30 is communicated with the clean water tank 21 through an air suction pipeline, and the pressure relief device is a two-position three-way electromagnetic valve disposed in the air suction pipeline. The two-position three-way electromagnetic valve is provided with a first path and a second path, the first path is used for communicating the pump 30 with the clean water tank 21, when the first path is opened, the pump 30 pumps air in the clean water tank 21 so as to enable the clean water tank 21 to form a negative pressure state, and when the second path is opened, air in the external environment flows into the clean water tank 21.
Therefore, only one two-position three-way electromagnetic valve is arranged in the air suction pipeline, and the pump 30 can be communicated with the clean water tank 21 by controlling the opening or closing of the first path and the second path, so that air in the clean water tank 21 can be conveniently sucked to form a negative pressure state, the air flows into the clean water tank 21, the internal and external air pressures of the clean water tank 21 are balanced, and the self-moving robot 20 can smoothly and stably leave the water adding device 10.
With continuing reference to fig. 1, fig. 3 and fig. 4, in addition, before the water is added into the clean water tank 21, in order to enable the pump 30 to pump out the air in the clean water tank 21, on the basis of any of the above embodiments, the pump 30 is disposed on the water adding device 10, the base of the water adding device 10 is provided with the first air port 12, the water adding container 11 is provided with the second air port 111, and the clean water tank 21 is provided with the third air port 211.
The air inlet of the pump 30 is directly communicated with the first air inlet 12 or communicated through a pipeline, the air outlet of the pump 30 is directly communicated with the second air inlet 111 or communicated through a pipeline, and when the self-moving robot 20 returns to the water adding device 10, the third air inlet 211 is in butt joint communication with the first air inlet 12.
During operation, air in the clean water tank 21 firstly flows into the pump 30 through the third air port 211 and the first air port 12, and then is pumped into the water replenishing container 11 by the pump 30, so as to achieve the purpose of forming a negative pressure state in the clean water tank 21. The air exhaust structure is simple, the air path is short, the speed of forming negative pressure in the clear water tank 21 is high, and the whole water replenishing process can be completed by the clear water tank 21 more quickly. It will be appreciated that when a negative pressure condition is established in the fresh water tank 21, a positive pressure condition is established in the refill container 11 as air is pumped into the refill container 11 by the pump 30, thereby facilitating the flow of fresh water from the refill container 11 into the fresh water tank 21.
In some embodiments, an air column protrudes from the base of the water adding device 10, and the first air port 12 is formed on the air column, and the air column can extend into the third air port 211 to communicate the first air port 12 with the third air port 211. After in the self-moving robot 20 returned to the device of adding water 10, the gas post stretched into in the third gas port 211 automatically, third gas port 211 and first gas port 12 automatic alignment intercommunication, and the gas post can play the positioning action this moment, guarantees that self-moving robot 20 parks stably and first gas port 12 and third gas port 211 butt joint intercommunication are reliable.
It will be appreciated that the air column is a hollow cylinder integrally formed or detachably mounted on the upper surface of the base of the watering device 10, and the first air vent 12 is an opening at the top of the air column. It should be noted, however, that the height of the air column should not interfere with the movement of the self-moving robot 20 so that the first air port 12 is normally connected to the third air port 211.
In some embodiments, a movable sealing plate is disposed at the third air port 211, and the sealing plate can be pushed by the air column to open the third air port 211. When the self-moving robot 20 is working normally, in order to prevent the clean water in the clean water tank 21 from leaking from the third air port 211 and prevent dust, pests and the like in the external environment from entering the clean water tank 21 from the third air port 211 to cause pollution, a sealing plate installed at the third air port 211 can seal the third air port 211, thereby preventing the above problems from occurring. When the self-moving robot 20 returns to the water adding device 10, the air column can automatically push the sealing plate away, so that the third air port 211 is communicated with the first air port 12, and the air in the clean water tank 21 can be conveniently extracted.
Further, seal the board through the pivot rotate set up in clear water tank 21's the mounting hole, just the pivot with be provided with the torsional spring between the mounting hole, not receive during the jacking force of gas post, the torsional spring makes seal the board and rotate to reset in order to incite somebody to action third gas port 211 closes. When the water is completely supplemented into the clear water tank 21, and the sealing plate pushed open under the action of the elastic torsion of the torsion spring can automatically rotate and reset after the mobile robot 20 leaves the water adding device 10, so that the third air port 211 is closed again, and the automation level of the equipment is improved.
Optionally, the sealing plate can be designed in a single-door or split-door structure, and is selected according to actual needs.
When the clean water tank 21 is in a dust-extraction negative pressure state, the water replenishing container 11 can be used for filling water into the clean water tank 21. In some embodiments, the base of the watering device 10 is provided with a first water port 13, the refill container 11 is provided with a second water port 112, and the clean water tank 21 is provided with a third water port 212. The first water gap 13 is directly communicated with the second water gap 112 or communicated with the second water gap through a pipeline, and when the self-moving robot 20 returns to the water adding device 10, the third water gap 212 is in butt joint communication with the first water gap 13. Since the pressure in the clean water tank 21 is negative and the pressure in the refill container 11 is positive after the pump 30 pumps the gas in the clean water tank 21, the water in the clean water tank can finally flow into the clean water tank 21 through the second water port 112, the first water port 13 and the third water port 212.
The pump 30 is configured to allow air and water to flow therethrough, and when the clean water tank 21 is full of water, the pump 30 is used to dynamically balance the amount of inlet and outlet water in the clean water tank 21. In the water replenishing process, when the water amount in the clean water tank 21 does not reach the preset height, the pump 30 sends gas into the water replenishing container 11 from the third air port 211 of the clean water tank 21 through the first air port 12 and the second air port 111, at the moment, the air pressure in the clean water tank 21 is reduced, meanwhile, the air pressure in the water replenishing container 11 is increased, under the action of the air pressure difference, the water in the water replenishing container 11 enters the first water port 13 through the second water port 112 and then enters the clean water tank 21 on the self-moving robot 20 from the first water port 13 and the third water port 212, and the water is added into the robot water tank;
when the water amount reaches the preset height, that is, when the water is full, the pump 30 pumps the clean water into the water replenishing container 11 through the second air port 111, and the water in the water replenishing container 11 is sent into the clean water tank 21 through the third water port 212, so that the water inlet amount and the water outlet amount in the clean water tank 21 reach dynamic balance. That is, when a sufficient time is set, the water in the clean water tank 21 can be filled up surely, and there is no fear of overflow after the water is filled up, because the water can be continuously pumped into the clean water tank by the pump 30 after the clean water tank 21 is filled up. In conclusion, the pump 30 in the scheme can continue pumping water after pumping gas, and can achieve the effect of pumping full water by setting enough pumping time, so that the technical means of common water full detection and the like can be omitted, the overall structure of the equipment is simpler, the cost is lower, and the reliability is higher.
