With the improvement of living standard of people, more and more families begin to assist cleaning by means of cleaning equipment, so as to reduce labor intensity and improve life quality. Existing cleaning equipment is generally composed of a base station and surface cleaning equipment, wherein the surface cleaning equipment (commonly used surface cleaning equipment comprises a sweeping robot, a window cleaning robot and the like) is used for sweeping and cleaning a room; the base station is used for charging the surface cleaning apparatus, supplying water, cleaning a cleaning portion (e.g., a roll brush) of the surface cleaning apparatus, and the like.

More and more basic stations in the market have at present and put in the cleaning solution function, for example install clear water tank and cleaning solution bottle in the basic station simultaneously, clear water tank can carry the clear water to surface cleaning equipment's cleaning portion on to wash cleaning portion. Meanwhile, the cleaning liquid bottle can add the cleaning liquid into the clean water tank, so that clean water is mixed into the cleaning agent, and the cleaning effect of the base station on the cleaning part is further improved. However, the existing cleaning device usually needs the user to manually supplement the cleaning liquid, which increases the burden of the user when using the device, and the operation is inconvenient and the product experience is not good. Meanwhile, the problems that the cleaning solution cannot be smoothly pumped out due to inaccurate liquid level detection of the cleaning solution and unreliable air release valves of the existing products generally exist.

Therefore, how to improve the structure of the base station to solve the problems of inaccurate liquid level detection of the cleaning liquid, unreliable air release valve, etc. existing in the base station, and further improve the experience of the user when using the device becomes a problem to be solved urgently in the field.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. It should be apparent that the embodiments described in this application are only some embodiments of the present application, and not all embodiments of the present application. All other embodiments, which can be obtained by a person skilled in the art without making any inventive step based on the embodiments in the present application, are within the scope of protection of the present application.

Referring to fig. 1 to 5, in an implementation, the base station a may at least include a body 100, the body 100 may have a receiving cavity 110, a placing port 130, and a cleaning area (not shown), and the receiving cavity 110 may have an upper and lower water module 200 and a cleaning solution bottle 300 installed therein. The placing port 130 is communicated with the accommodating cavity 110, so that the upper and lower water modules 200 and the cleaning liquid bottle 300 can enter the accommodating cavity 110 through the placing port 130. When the upper and lower water modules 200 and the cleaning liquid bottle 300 are fixed inside the accommodating cavity 110, the projection of the cleaning liquid bottle 300 on the plane where the placing port 130 is located is at least partially overlapped with the placing port 130, that is, the installation position of the cleaning liquid bottle 300 is within the coverage range of the placing port 130, so that the cleaning liquid bottle 300 can be directly fixed inside the accommodating cavity 110 through the placing port 130.

In practical applications, the body 100 may be configured as a barrel-shaped cavity, and an opening (i.e., the placing port 130) is disposed at the top of the barrel-shaped cavity, so that a user can directly mount and dismount the cleaning solution bottle 300 through the placing port 130. Meanwhile, a portion of the barrel-shaped cavity may exist as the accommodating cavity 110, at this time, the sidewall of the body 100 (i.e., the sidewall of the barrel-shaped cavity) is the sidewall of the accommodating cavity 110, and the installation positions of the upper and lower water modules 200 and the cleaning liquid bottle 300 are located inside the sidewall of the body 100. Therefore, an external protruding cavity for accommodating the cleaning solution bottle 300 is not required to be additionally arranged on the side wall of the body 100, and the overall structure of the base station a can be simpler.

The upper and lower water modules 200 communicate with the clean area so that the upper and lower water modules 200 can supply water to the clean area and extract liquid accumulated in the clean area. The cleaning liquid bottle 300 can contain cleaning liquid therein, and the cleaning liquid bottle 300 can be communicated with the cleaning area through the liquid supply mechanism 400, so that the liquid supply mechanism 400 can guide the cleaning liquid in the cleaning liquid bottle 300 to the cleaning area.

Particularly, basic station A can be through setting up the module 200 that goes up and down to provide the clear water to the clearance area, and set up cleaning solution bottle 300 and provide the cleaning solution to the clearance area, cleaning solution and clear water hold respectively in the container of difference, the user need not to mix cleaning solution and clear water in same container in advance, this also makes the user when replenishing the clear water to the clear water tank, need not to replenish the cleaning solution again, the allotment, burden when lightening user's user equipment.

Further, in the present embodiment, the upper and lower water modules 200 and the cleaning solution bottle 300 are installed in the same accommodating cavity 110, so that an additional installation position for placing the cleaning solution bottle is not required, which not only makes the overall structure of the base station a simpler, but also reduces the manufacturing cost of the base station a. When a user replaces or replenishes any one of the cleaning liquid bottle 300 and the upper and lower water modules 200, the user can simultaneously observe the working states of the cleaning liquid bottle 300 and the upper and lower water modules 200, and then adjust the cleaning liquid bottle 300 or the upper and lower water modules 200 according to the working states of the modules, thereby improving the working reliability of the base station a. For example, in an application scenario, when the upper and lower water modules 200 need to be repaired, a user may open the upper cover of the base station a, and then repair the upper and lower water modules 200 in the accommodating cavity 110. Since the cleaning liquid bottle 300 and the upper and lower water modules 200 are both located in the accommodating cavity 110, the user can know the working status of the cleaning liquid bottle 300, such as observing whether the cleaning liquid bottle 300 leaks or not, or observing the remaining condition of the cleaning liquid in the cleaning liquid bottle 300.

In practical applications, the cleaning area may be an accommodating space formed on one side of the body 100 and having an inlet and an outlet, and a water collecting tank (not shown) and a cleaning mechanism (not shown) may be further disposed in the accommodating space. The base station a is typically placed on the floor in use to facilitate entry of a surface cleaning apparatus, such as a sweeping robot, a bump robot or other cleaning robot, into the receiving space (i.e. into the cleaning area). When the surface cleaning apparatus enters the cleaning zone, the base station a may perform operations such as charging the surface cleaning apparatus and cleaning the cleaning portion of the surface cleaning apparatus. Specifically, after the surface cleaning device enters the cleaning area through the inlet and outlet, the water feeding and discharging module 200 can supply clean water to the cleaning area, and the cleaning liquid bottle 300 supplies cleaning liquid to the cleaning area through the liquid supply mechanism 400, and then the cleaning mechanism cleans the cleaning part of the surface cleaning device. Further, the sewage formed in the above cleaning process can be collected in the water collecting tank, and the sewage in the cleaning area is extracted by the water feeding and discharging module 200, so that the function of automatically discharging the sewage is realized.

Based on the above-mentioned arrangement mode that the cleaning solution and the clean water are not required to be prepared in the same container in advance, and the function of automatically discharging the sewage, the water supply and drainage module 200 in the present application can adopt various embodiments, and the following detailed description is made of three realizable embodiments, but not limited thereto.

In a first embodiment of the upper and lower water modules 200, please refer to fig. 2 and 3 together, the upper and lower water modules 200 may include a first water tank 210 and a second water tank 220. The first water tank 210 is communicated with the cleaning area through the guide assembly 230, so that the guide assembly 230 can guide the clean water in the first water tank 210 to the cleaning area. The second tank 220 communicates with the cleaning zone via a return assembly (not shown) so that the return assembly can draw liquid from the cleaning zone into the second tank 220. Wherein the cleaning liquid bottle 300 may be disposed between the first water tank 210 and the second water tank 220, but is not limited thereto, for example, the cleaning liquid bottle 300 may be disposed at the right side of the first water tank 210, or the cleaning liquid bottle 300 may be disposed at the left side of the second water tank 220, etc.

In practical applications, the first water tank 210 may be used as a clean water tank, and the second water tank 220 may be used as a dirty water tank. When the surface cleaning apparatus is located in a cleaning area and the cleaning portion of the surface cleaning apparatus needs to be cleaned, the diversion assembly 230 diverts the liquid in the first water tank 210 to the cleaning area and cleans the cleaning portion of the surface cleaning apparatus, and at the same time, the backflow assembly draws the sewage located in the cleaning area into the second water tank 220 for storage. In an implementation manner, in order to enable the sewage in the cleaning area to be pumped into the second water tank 220 for storage, the backflow assembly may include a water pump and a backflow pipe, the backflow assembly pumps the sewage in the cleaning area through the water pump, and the pumped sewage is guided into the second water tank 220 along the backflow pipe.

It should be noted that the first water tank 210 and the second water tank 220 defined in the present application may be respectively used as independent structures, where the independent structures refer to that the first water tank 210 and the second water tank 220 are respectively detachably connected in the accommodating cavity 110 of the body 100, so as to facilitate the detachment and installation of the first water tank 210 and the second water tank 220 from the body 100. Of course, the first and

second water tanks

210 and 220 may not be independent structures, and for example, two separated water storage spaces may be formed inside the receiving chamber 110 to be used as the first and

second water tanks

210 and 220, respectively.

Furthermore, in order to guarantee that the two sides of the base station A are stressed in a balanced manner, the deformation of single-end pressure loss of a cushion pad at the bottom of the base station A caused by overlarge stress on the single side of the base station A is avoided, and the gravity center balance design can be carried out on the base station A. Since whether the center of gravity of the base station a is balanced depends mainly on the distribution of the center of mass of the cleaning liquid bottle 300, the first water tank 210 and the second water tank 220, the positions of the cleaning liquid bottle 300, the first water tank 210 and the second water tank 220 may be set.

In an implementable embodiment, the body 100 may have a first plane of symmetry 120, the plane of symmetry of the cleaning solution bottle 300 coincides with the first plane of symmetry 120, and the first and

second water tanks

210 and 220 are located on both sides of the cleaning solution bottle 300. Further, the first and

second water tanks

210 and 220 are symmetrically disposed about or approximately about the first plane of symmetry 120. Through the above arrangement, the cleaning solution bottle 300 can be located in the middle of the base station a, and the first water tank 210 and the second water tank 220 are substantially symmetrically arranged on the two sides of the base station a, so that the two sides of the base station a can be stressed evenly, and the center of gravity of the base station a is more stable.

In the second embodiment of the upper and lower water modules 200, the upper and lower water modules 200 may not employ the first and

second water tanks

210 and 220, but directly guide the external water supply to the cleaning region, and simultaneously, the sewage in the cleaning region may be directly discharged. Specifically, the sewage module 200 may include a clean water pipe (not shown) and a sewage drain pipe (not shown). The clean water pipe can directly communicate an external clean water supply port (which can be a household faucet or the like in general) with the cleaning area, so that water is directly supplied to the cleaning area from the external clean water supply port. The sewage pipe can directly communicate the cleaning area with the sewer, so that sewage generated in the cleaning area is directly discharged into the sewer. So, compare in the first concrete embodiment of upper and lower water module 200, the user need not regularly to clear up the blowdown to the sewage case, also need not to carry out the moisturizing to the clear water case, has further alleviateed user's use burden.

In the third embodiment of the upper and lower water modules 200, the upper and lower water modules 200 may be combined with the first water tank 210 by using a sewage pipe, or combined with the second water tank 220 by using a clean water pipe, so that the installation environment requirements of the upper and lower water modules 200 can be appropriately reduced.

The above sewage module 200 is described by taking a combination of the sewage pipe and the first water tank 210 as an example. The first tank 210 may guide the liquid into the cleaning region through the guide assembly 230, thereby cleaning a cleaning part of the surface cleaning apparatus. The clearance is regional through sewage pipe and sewer direct intercommunication, so, the sewage of piling up in the clearance region can directly be discharged to the sewer in through the sewage pipe. Compared with the first specific embodiment of the water feeding and discharging module 200, the user does not need to clean and discharge the sewage tank regularly, and the use burden of the user is reduced.

As for the structure of the cleaning liquid bottle 300, two types may be included, one type in which the inside air of the cleaning liquid bottle 300 is not communicated with the outside air, and the other type in which the inside air of the cleaning liquid bottle 300 is communicated with the outside air. Therefore, in order to enable the base station a to apply the two types of cleaning solution bottles 300 at the same time and stably extract the cleaning solution in the cleaning solution bottles 300, the present application provides a liquid supply mechanism 400, which is shown in fig. 3, 4, 5, 6 and 7. In an implementation, the liquid supply mechanism 400 may include a liquid storage tank 410, a liquid guide tube 420 and a liquid pumping device 430, the cleaning liquid in the cleaning liquid bottle 300 first flows into the liquid storage tank 410 through the liquid guide tube 420, the cleaning liquid in the liquid storage tank 410 may be buffered as a solution, and when the cleaning liquid needs to be pumped, the cleaning liquid is directly pumped from the liquid storage tank 410 by the liquid pumping device 430.

Specifically, the liquid storage tank 410 may be provided with a vent 411 and a liquid storage cavity 412, wherein the liquid storage cavity 412 is communicated with the outside air through the vent 411. The liquid guide tube 420 is used for communicating the cleaning liquid bottle 300 with the liquid storage cavity 412. When the liquid storage cavity 412 is communicated with the interior of the cleaning liquid bottle 300 through the liquid guide tube 420, the cleaning liquid bottle 300 should be located above the liquid storage cavity 412, and the bottom end surface 421 of the liquid guide tube 420 is located below the air vent 411. The inlet of the fluid evacuation device 430 communicates with the reservoir 412 through the transition section 440, and the opening of the transition section 440 in the interior of the reservoir 412 is disposed below the bottom end surface 421 of the catheter 420, such that the fluid evacuation device 430 can draw cleaning fluid from the reservoir 412. Meanwhile, the outlet of the fluid pumping device 430 is communicated with the cleaning region, so that the cleaning fluid pumped from the fluid storage chamber 412 can be guided to the cleaning region.

It should be noted that, when the cleaning liquid bottle 300 is communicated with the liquid storage cavity 412 through the liquid guiding tube 420, the air pressure in the liquid storage cavity 412 will be consistent with the external air pressure due to the air holes 411. Since the cleaning liquid bottle 300 is located above the liquid storage cavity 412, the cleaning liquid in the cleaning liquid bottle 300 can flow into the liquid storage cavity 412 through the liquid guide tube 420 under the action of its own gravity. With the cleaning liquid in the cleaning liquid bottle 300 continuously flowing into the liquid storage cavity 412, when the liquid level of the cleaning liquid in the liquid storage cavity 412 is flush with the bottom end surface 421 of the liquid guiding tube 420, the cleaning liquid in the liquid storage cavity 412 forms a liquid seal effect on the bottom end surface 421 of the liquid guiding tube 420, so that the cleaning liquid in the cleaning liquid bottle 300 does not continuously flow into the liquid storage cavity 412 any more, and the liquid level in the liquid cavity 412 is kept stable.

Meanwhile, since the bottom end surface 421 of the liquid guide tube 420 is located below the air holes 411, the cleaning liquid in the liquid storage cavity 412 does not flow out of the air holes 411. Correspondingly, when the level of the cleaning liquid in the liquid storage chamber 412 is flush with the bottom end surface 421 of the liquid guiding tube 420, the cleaning liquid in the liquid storage chamber 412 forms a liquid seal effect on the bottom end surface 421 of the liquid guiding tube 420, so that the bottom end surface 421 of the liquid guiding tube 420 divides the liquid storage chamber 412 into an air space and a liquid space which are arranged up and down. To enable the fluid extraction device 430 to extract the cleaning fluid, the opening of the transition section 440 in the interior of the reservoir 412 should be disposed below the bottom end surface 421 of the catheter 420 to extract the cleaning fluid from the reservoir 412.

In practical applications, the structure for communicating the air in the liquid storage cavity 412 with the outside air may be not only the air vent 411, but also a structure such as a release valve, which is not limited in this application. Further, the catheter 420 and the reservoir 410 may be integrally formed, for example, the catheter 420 and the reservoir 410 may be blow molded or 3D printed, and the catheter 420 and the reservoir 412 are connected during the molding process. Of course, the catheter 420 and the liquid storage tank 410 may also be designed separately, for example, the catheter 420 and the liquid storage tank 410 are produced separately, and a threaded hole is reserved at the top end of the liquid storage tank 410, and the catheter 420 may be connected with the threaded hole in a threaded manner, so as to detachably connect the catheter 420 and the liquid storage tank 410. Further, the reservoir 410 may be constructed in two parts of an upper case and a lower case, which are coupled to form a rear reservoir 412, and the catheter 420 is integrally formed with the upper case.

It should be noted that the specific structure of the liquid pumping device 430 defined in the present application may refer to a water pump or other liquid pumping devices in the prior art, and will not be described herein again. The transition section 440 defined herein may be a communication joint for interconnecting the water inlet of the fluid extraction device 430 with the reservoir 410. Of course, to facilitate the installation arrangement of the pumping device 430, a communication conduit 431 may be connected between the pumping device 430 and the transition section 440. For example, in one application, the transition piece 440 may be secured to the tank 430, and the transition piece 440 may be in communication with the tank cavity 412, while the pumping device 430 is in communication with the transition piece 440 via the communication conduit 431.

Further, in order to timely determine whether the cleaning liquid in the cleaning liquid bottle 300 is exhausted. In one implementation, as shown in fig. 4-7, the liquid supply mechanism 400 may further include a liquid level sensor 450, and the liquid level sensor 450 is used for detecting the level of the cleaning liquid in the liquid storage chamber 412 to determine whether the volume of the cleaning liquid in the liquid storage chamber 412 is lower than a predetermined volume. It should be noted that, since the cleaning liquid bottle 300 is communicated with the liquid storage cavity 412 through the liquid guiding tube 420, the cleaning liquid in the cleaning liquid bottle 300 can enter the liquid storage cavity 412 through the liquid guiding tube 420, and therefore, whether the cleaning liquid in the cleaning liquid bottle 300 is exhausted can be determined by determining whether the volume of the cleaning liquid in the liquid storage cavity 412 is lower than the preset volume.

In practical applications, the predetermined volume may be preset by a technician according to the structure of the reservoir chamber 412. For example, taking the region of the transition section 440 between the opening in the reservoir 412 and the bottom surface of the reservoir 412, assuming that the region can hold 20ml of fluid and 80ml of fluid from the bottom surface of the reservoir 412 to the bottom end surface 421 of the catheter 420, the technician can select a value in the range of 20ml to 80ml as the predetermined volume.

Further, the level sensor 450 may employ a probe level gauge 451. Specifically, as shown in FIG. 7, the probe level gauge 451 may be mounted on the tank 410 with the lower surface of the probe level gauge 451 below the bottom end surface 421 of the catheter 420 and the lower surface of the probe level gauge 451 above the transition section 440.

It should be noted that since the probe level gauge 451 is capable of generating a current change according to a contact condition of the lower surface thereof with the liquid, it is possible to determine whether the liquid level in the tank 410 is lower than the lower surface of the probe level gauge 451 according to a current change condition of the probe level gauge 451. In practical applications, when the cleaning liquid in the cleaning liquid bottle 300 is exhausted, the cleaning liquid bottle 300 cannot continue to supply the cleaning liquid to the chamber 412, and the level of the cleaning liquid in the chamber 412 decreases with the continuous pumping of the pumping device 430, and when the level of the cleaning liquid in the chamber 412 decreases to below the transition section 440, the pumping device 430 cannot pump the cleaning liquid. Therefore, in order to effectively detect whether the cleaning solution in the cleaning solution bottle 300 is exhausted and ensure the cleaning solution in the liquid storage chamber 412 is extracted by the liquid extraction device 430, the lower surface of the probe level gauge 451 should be located between the bottom end surface 421 of the liquid guide tube 420 and the transition section 440.

In one implementation, as the extraction device 430 continuously extracts cleaning solution from the chamber 412, the level of cleaning solution in the chamber 412 decreases as the cleaning solution bottle 300 is depleted. When the liquid level in the liquid storage cavity 412 drops below the lower surface of the probe liquid level meter 451, the probe liquid level meter 451 generates current change, and the base station a can convert the current change into an alarm signal (such as a buzzer or a short message), so as to remind a user to replace the cleaning liquid bottle 300.

Further, the probe level gauge 300 can avoid misjudgment of the liquid level in the liquid storage cavity 412 due to water drops on the inner side wall of the liquid storage cavity 412. The probe level gauge 300 can also be configured to have a predetermined distance 452 from an inner sidewall of the reservoir cavity 412. The preset distance 452 may be preset by a technician according to an empirical value.

It should be noted that the probe level gauge 451 described above is only one embodiment of the level sensor 450, but is not limited thereto. Meanwhile, the specific structure of the probe level gauge 451 can refer to the prior art, and is not described in detail herein.

In order to ensure that the cleaning liquid bottle 300 can be accurately communicated with the liquid guide tube 420 when the cleaning liquid bottle 300 is installed in the accommodating cavity 110, in an implementation manner, please refer to fig. 6, 8 and 9 together, the liquid supply mechanism 400 may further include a limiting member 460, and the limiting member 460 is used for positioning the cleaning liquid bottle 300, so that the cleaning liquid bottle 300 can be accurately communicated with the liquid guide tube 420 when the cleaning liquid bottle 300 is installed in the accommodating cavity 110 through the limiting member 460. Specifically, the limiting member 460 is located in the accommodating cavity 110, and the limiting member 460 may form the limiting space 470 alone, or the limiting member 460 and the inner wall of the accommodating cavity 110 together form the limiting space 470. The top end surface 422 of the liquid guide tube 420 is located in the limit space 470, and when the cleaning liquid bottle 300 is located in the limit space 470, the inner side wall of the limit space 470 limits the outer wall of the cleaning liquid bottle 300, so that the top end surface 422 of the liquid guide tube 420 can be accurately inserted into the cleaning liquid bottle 300.

In practical applications, the shape of the spacing space 470 can be configured to be a contour according to the shape of the cleaning solution bottle 300. For example, when the cleaning solution bottle 300 has a rectangular parallelepiped shape, the spacing space 470 may be configured in a rectangular parallelepiped shape. Furthermore, the position-limiting element 460 may be an independent structure, for example, the position-limiting element 460 is manufactured as a single component, and when the position-limiting element 460 is installed in the accommodating cavity 110, the position-limiting element 460 may be fixed on the bottom surface of the accommodating cavity 110 by using a hot melting, magnetic attraction, or screw connection method. It should be noted that the limiting member 460 may also be formed integrally with the body 100, which is not limited in the present application.

In an implementation, referring to fig. 7 in particular, in order to allow the top end surface 422 of the catheter 420 to be located in the accommodating cavity 110, an abdicating hole 111 may be provided on the body 100, so that the top end surface 422 of the catheter 420 can pass through the abdicating hole 111 and enter the accommodating cavity 110.

Further, the cleaning solution bottle 300 is conveniently placed in the space 470. In one practical embodiment, shown in fig. 8 and 9, the top of the confinement space 470 has an open structure to form an access port 471, and the top end surface 422 of the catheter 420 is located at the bottom of the confinement space 470. When the cleaning liquid bottle 300 enters the limiting space 470 through the releasing port 471, the top end surface 422 of the liquid guiding tube 420 can be inserted into the cleaning liquid bottle 300, so as to communicate the cleaning liquid bottle 300 with the liquid guiding tube 420. Thus, by vertically inserting the cleaning solution bottle 300 into the spacing space 470, since the center of gravity of the cleaning solution bottle 300 faces downward, a downward pushing force of a part of users can be saved, so that the catheter 420 can be more easily inserted into the cleaning solution bottle 300, thereby facilitating the installation of the cleaning solution bottle 300.

It should be noted that the above-mentioned solution of disposing the releasing port 471 at the top of the limit space 470 to enable the cleaning solution bottle 300 to be vertically inserted into the limit space 470 is only a preferred embodiment, but not limited thereto, and the releasing port 471 can be disposed at any position of the limit space 470. Accordingly, the cleaning liquid bottle 300 may be inserted obliquely into the restraining space 470 based on the position of the putting-in port 471, or the cleaning liquid bottle 300 may be pushed into the restraining space 470 from the side.

In an implementation, when the putting port 471 is inclined toward the putting port 130, the cleaning solution bottle 300 can be obliquely inserted into the limit space 470 through the putting port 471. Correspondingly, the top end surface 422 of the catheter 420 is located at the bottom of the spacing space 470 and is parallel to the side wall of the spacing space 470. In this way, when the user inserts the cleaning liquid bottle 300 into the limiting space 470 along the entrance 471, the top end surface 422 of the catheter 420 can be inserted into the cleaning liquid bottle 300.

In another practical implementation, when the releasing port 471 is located at one side of the limiting space 470, the cleaning liquid bottle 300 may be vertically placed inside the accommodating chamber 110 through the releasing port 130, and then the cleaning liquid bottle 300 is horizontally pushed toward the direction of the releasing port 471, so that the cleaning liquid bottle 300 enters the limiting space 470. Correspondingly, the top end surface 422 of the catheter 420 should be located at the bottom of the spacing space 470, and the top end surface 422 of the catheter 420 is arranged perpendicular to the entrance 471. Thus, when the user horizontally pushes the cleaning liquid bottle 300 toward the direction of the discharging port 471, so that the cleaning liquid bottle 300 enters the limiting space 470, the top end surface 422 of the liquid guiding tube 420 can be inserted into the cleaning liquid bottle 300 through the insertion connection portion of the cleaning liquid bottle 300.

Further, the height of the limiting member 460 should be lower than that of the cleaning liquid bottle 300, so that when the cleaning liquid bottle 300 is installed in the limiting space 470, the cleaning liquid bottle 300 can be partially exposed out of the limiting space 470, and thus, when the cleaning liquid bottle 300 is replaced by a user, the cleaning liquid bottle 300 can be conveniently grabbed.

In practice, the cleaning solution in the reservoir 412 will generally shake when the base station A is moving. To prevent the cleaning liquid from flowing out of the air holes 411, in an implementation, a waterproof member may be disposed at the air holes 411, and the waterproof member may prevent the cleaning liquid in the liquid storage chamber 412 from flowing out of the air holes 411. With respect to the specific structure of the flashing, the present application provides two specific examples, but is not limited thereto.

The first embodiment is as follows: referring to fig. 4, the air holes 411 may be covered with a waterproof air permeable membrane 480. The waterproof air permeable membrane 480 is used for preventing the cleaning liquid in the liquid storage cavity 412 from flowing out through the air holes 411, and enabling the air in the liquid storage cavity 412 to be communicated with the outside air. So, waterproof ventilated membrane 480 both can realize the intercommunication of stock solution cavity 412 with the outside air to make the cleaning solution in the cleaning solution bottle 300 can be stable flow in to stock solution cavity 412, can guarantee again that when basic station A takes place to rock, the cleaning solution in the stock solution cavity 412 can't spill over through bleeder vent 411, thereby play waterproof effect.

It should be noted that the specific structure of the waterproof breathable membrane 480 can be found in the prior art, and will not be described herein.

Example two: a ventilation tube (not shown) may be provided on the reservoir tank 410. Specifically, the vent pipe is communicated with the vent holes 411, and the vent pipe extends outwards along the outer wall of the liquid storage tank 410 to prevent the cleaning liquid in the liquid storage cavity 412 from flowing out through the vent holes 411.

In practical application, the vent pipe may be integrally formed with the liquid storage tank 410, or may be detachably connected to the vent holes 411. Further, regarding the specific shape of the ventilation tube, it may be disposed to extend vertically upward, and may also be disposed to extend upwardly in a curved manner, which is not specifically limited in this application.

In an implementation, in order to prevent the cleaning liquid provided by the cleaning liquid bottle 300 from being utilized insufficiently, the cleaning liquid provided by the cleaning liquid bottle 300 and the clean water provided by the upper and lower water modules 100 may be mixed sufficiently, and then the mixed liquid may be guided to the cleaning portion of the surface cleaning apparatus. Specifically, as shown in fig. 3, the flow guide assembly 230 may include a first passage 231 and a second passage 232, wherein one end of the first passage 231 is communicated with the first water tank 210, and the other end of the first passage 231 is communicated with the second passage 232. One end of the second channel 232 is located in the cleaning area, and the other end of the second channel 232 is communicated with the water outlet of the liquid pumping device 430. Thus, the clean water in the first water tank 210 can flow into the cleaning area through the first channel 231 and the second channel 232 in sequence, and the cleaning liquid pumped by the liquid pumping device 430 can flow into the cleaning area through the second channel 232. So, when the cleaning solution that pumping device 430 extracted to and the clear water in the first water tank 210 need flow into to the clearance regional simultaneously, the cleaning solution that pumping device 430 was taken out just can mix in second passageway 232 with the clear water in the first water tank 210, and the cleaning solution will be with the clear water intensive mixing, and the reentrant is to the clearance regional, thereby realizes carrying out make full use of to the cleaning solution.

In practical applications, the water outlet of the liquid pumping device 430, the first passage 231 and the second passage 232 may be communicated with each other by the three-way valve 500. Thus, the clean water flowing out of the first channel 231 and the cleaning liquid extracted by the liquid extracting device 430 can meet and mix at the three-way valve 500, and then enter the second channel 232 together, and then flow into the cleaning area through the second channel 232. Further, a water pump may be connected in series to the first channel 231, and the water pump may pump out the clean water in the first water tank 210. Of course, the clean water in the first water tank 210 may flow into the first channel 231 by its own weight. Further, an electric control valve may be further disposed in the first channel 231, and the on-off of the first channel 231 is controlled by the electric control valve, so as to control the flowing state of the clean water in the first water tank 210.

It should be noted that the first channel 231 and the second channel 232 defined herein are channels having a communication function, and may be external pipes, or channels formed inside the body 100, and are not limited herein.

Optionally, to further improve the cleaning effect of the base station a on the cleaning portion of the surface cleaning apparatus. Referring to fig. 3, in an implementation, the diversion assembly 230 may further include a heating device 233, and the cleaning liquid pumped by the liquid pumping device 430 and the clean water in the first water tank 210 are heated by the heating device 233, so as to improve the cleaning effect of the cleaning liquid and the clean water on the cleaning portion of the surface cleaning apparatus.

In practical applications, the heating device 233 may be connected in series to the first channel 231. Like this, when the clear water in first water tank 210 flows through heating device 233, heating device 233 can heat the clear water of flowing through, when this clear water flows into to second passageway 232 in, the clear water after the intensification will mix with the cleaning solution, so just realized carrying out the effect of heating to the cleaning solution. It should be noted that the heating device 233 may also be connected in series to the second channel 232, or the heating device 233 is installed at the water outlet of the liquid pumping device 430, and the specific structure of the heating device 233 may refer to an existing heater, which is not described herein again.

Regarding the specific structure of the cleaning liquid bottle 300, in an implementation manner, please refer to fig. 7 and 10 together, the cleaning liquid bottle 300 may include a bottle body 310 and a bottle cap 320, the bottle body 310 is detachably connected to the bottle cap 320, and when the cleaning liquid in the cleaning liquid bottle 300 is exhausted, a user may open the bottle cap 320 to replenish the cleaning liquid in the cleaning liquid bottle 300. It should be noted that the bottle body 310 and the bottle cap 320 may also be configured as a non-detachable structure to simplify the structure of the cleaning solution bottle 300 and improve the sealing performance of the cleaning solution bottle 300. The cap 320 may further have an elastic portion 321, and when the top end 422 of the catheter 420 passes through the elastic portion 321 and enters the bottle body 310, the elastic portion 321 may seal a gap between the catheter 420 and the cap 320.

It is understood that the elastic portion 321 may have at least two usage modes.

In an implementation manner, the elastic portion 321 may be covered at the preformed hole 322 of the bottle cap 320 as a soft glue head, and the elastic portion 321 and the bottle cap 320 together seal the outlet of the bottle body 310, so as to prevent the cleaning liquid in the cleaning liquid bottle 300 from leaking out when the cleaning liquid bottle 300 is not used. In practical applications, when the top end surface 422 of the liquid guiding tube 420 pierces the elastic portion 321 to enter the bottle body 310, the elastic portion 321 can seal the contact area between the bottle cap 320 and the liquid guiding tube 420 under the elastic action of the elastic portion 321, so as to prevent the cleaning liquid in the cleaning liquid bottle 300 from leaking out.

In another practical implementation, the elastic part 321 can also be coaxially arranged as a sealing ring at the preformed hole 322 of the bottle cap 320, and the middle aperture of the elastic part 321 is smaller than the outer diameter of the catheter 420. Correspondingly, a sealing film (not shown) may be further disposed at the outlet of the bottle body 310, and the sealing film is used to prevent the cleaning solution in the bottle body 310 from leaking out when the bottle body 310 is not in use. In practical applications, the top surface 422 of the catheter 420 first passes through the middle aperture of the elastic portion 321 into the bottle cap 320, and then the top surface 422 pierces the sealing film to enter the bottle body 310, so that the cleaning liquid in the cleaning liquid bottle 300 can flow into the liquid storage chamber 412 from the catheter 420. Meanwhile, since the middle aperture of the elastic part 321 is smaller than the outer diameter of the liquid guide tube 420, the elastic part 321 can seal the contact area between the bottle cap 320 and the liquid guide tube 420, thereby preventing the cleaning liquid in the cleaning liquid bottle 300 from leaking out.

Further, the top end surface 422 may be needle-shaped, so as to facilitate the top end surface 422 to pierce the elastic portion 321 or the sealing film.

Based on the same inventive concept, the present application further provides a liquid supply mechanism 400, wherein the liquid supply mechanism 400 at least comprises a liquid storage tank 410, a liquid guide pipe 420 and a liquid pumping device 430. The liquid storage tank 410 has a vent 411 and a liquid storage cavity 412, wherein the liquid storage cavity 412 is communicated with the outside air through the vent 411.

The inlet of the drawing device 430 communicates with the reservoir chamber 412 through a transition section 440, and the transition section 440 is located below the bottom end surface 421 of the liquid guide tube 420.

Further, the liquid supply mechanism 400 further comprises a liquid level sensor 450. The level sensor 450 is used to detect the level of the cleaning liquid in the chamber 412 to determine whether the volume of the cleaning liquid in the chamber 412 is less than a predetermined volume.

The body 100 has a cleaning area (not shown) for receiving and cleaning the surface cleaning apparatus, a placing port 130, and a receiving chamber 110. The placing port 130 is communicated with the accommodating cavity 110, so that the upper and lower water modules 200 and the cleaning liquid bottle 300 can enter the accommodating cavity 110 through the placing port 130, and when the upper and lower water modules 200 and the cleaning liquid bottle 300 are installed in the accommodating cavity 110, the projection of the cleaning liquid bottle 300 on the plane where the placing port 130 is located should at least partially coincide with the placing port 130. The upper and lower water modules 200 and the cleaning solution bottle 300 are installed in the accommodating chamber 110. The upper and lower water modules 200 communicate with the cleaning zone to supply water to the cleaning zone and to withdraw liquid from the cleaning zone. The cleaning liquid bottle 300 is communicated with the cleaning area through the liquid supply mechanism 400, and when the surface cleaning device is located in the cleaning area, the liquid supply mechanism 400 guides the cleaning liquid in the cleaning liquid bottle 300 to the cleaning part of the surface cleaning device.

Further, the upper and lower water modules 200 include at least a first water tank 210 and a second water tank 220, wherein the cleaning solution bottle 300 is disposed between the first water tank 210 and the second water tank 220. The first tank 210 communicates with the cleaning region through the guide assembly 230 to guide the liquid in the first tank 210 to the cleaning region. The second tank 220 communicates with the cleaning zone via a return assembly to draw liquid from the cleaning zone into the second tank 220.

It should be particularly noted that the specific form of the surface cleaning device may be a device such as a floor sweeping robot, a window cleaning robot, a cleaning machine, and the like, the specific form of the base station a may be a service site providing functions such as cleaning and charging for the surface cleaning device, and the specific structure of the base station a may refer to relevant contents in the foregoing embodiments, and details are not described here.

Based on the same inventive concept, the present application further provides a residual liquid detection method for a cleaning device, the cleaning device at least may include a liquid supply mechanism 400 and a cleaning liquid bottle 300, the liquid supply mechanism 400 includes a liquid storage tank 410, a liquid guide tube 420, a liquid drawing device 430 and a probe liquid level meter 450, the liquid storage tank 410 has a vent hole 411 and a liquid storage cavity 412, wherein the liquid storage cavity 412 is communicated with the outside air through the vent hole 411, the liquid guide tube 420 is communicated with the liquid storage cavity 412, and a bottom end surface 421 of the liquid guide tube 420 is located below the vent hole 411, so that the cleaning liquid in the cleaning liquid bottle 300 enters the liquid storage cavity 412 through the liquid guide tube 420, a water inlet of the liquid drawing device 430 is communicated with the liquid storage cavity 412 through a transition section 440, and the transition section 440 is located below the bottom end surface 421 of the liquid guide tube 420, the probe liquid level meter 450 is installed on the liquid storage tank 410, and a lower surface of the probe liquid level meter 450 is located below the bottom end surface 421 of the liquid guide tube 420, and a lower surface of the probe liquid level meter 450 is located above the transition section 440, wherein the residual liquid level meter detection method includes:

judging whether the cleaning liquid in the cleaning liquid bottle 300 is exhausted;

if the cleaning liquid in the cleaning liquid bottle 300 is exhausted, the liquid pumping device 430 is controlled to stop pumping liquid, and a message of replenishing the cleaning liquid is fed back to the user.

When the liquid pumping device 430 pumps the cleaning liquid in the liquid storage cavity 412, the control unit 600 in the cleaning apparatus can determine whether the cleaning liquid in the cleaning liquid bottle 300 is exhausted, and when the cleaning liquid in the cleaning liquid bottle 300 is exhausted, the control unit 600 can control the liquid pumping device 430 to stop pumping, so as to prevent the liquid pumping device 430 from being damaged during idle running, and remind the user of replenishing the cleaning liquid.

In an implementation manner, referring to fig. 11, whether the cleaning liquid in the cleaning liquid bottle 300 is exhausted can be indirectly obtained by providing a probe liquid level meter 450 on the liquid storage tank 410, wherein the probe liquid level meter 450 is used for detecting whether the liquid level of the cleaning liquid in the liquid storage cavity 412 is lower than the lower surface of the probe liquid level meter 450, and the control unit 600 is electrically connected to the probe liquid level meter 450 and the liquid pumping device 430.

Correspondingly, the determination of whether the cleaning liquid in the cleaning liquid bottle 300 is exhausted can be realized by the following steps: determining whether the level of the cleaning liquid in the liquid storage chamber 412 is lower than the lower surface of the probe level gauge 450; if the level of the cleaning solution in the liquid storage cavity 412 is lower than the lower surface of the probe liquid level meter 450, the cleaning solution in the cleaning solution bottle 300 is exhausted; if the level of the cleaning solution in the reservoir chamber 412 is not lower than the lower surface of the probe level gauge 450, the cleaning solution in the cleaning solution bottle 300 is not depleted.

In other words, the control unit 600 monitors the current of the probe level gauge 450, and when the current of the probe level gauge 450 changes, it indicates that the level of the cleaning liquid in the liquid storage chamber 412 is lower than the lower surface of the probe level gauge 450, so that it can be determined that the cleaning liquid in the cleaning liquid bottle 300 is exhausted. When the cleaning liquid in the cleaning liquid bottle 300 is exhausted, the control unit 600 can control the liquid pumping device 430 to stop operation, and simultaneously prompt the user to replenish the cleaning liquid.

In practical applications, the control unit 600 may be an MCU module, and the liquid pumping device 430 may be a water pump. Whether the cleaning solution liquid level in the stock solution cavity 412 is less than the lower surface of probe level gauge 450 by probe level gauge 450 detection, when the cleaning solution liquid level in the stock solution cavity 412 is less than the lower surface of probe level gauge 450, current change can take place for probe level gauge 450, thereby acquire this current change information by the MCU module, judge that the cleaning solution in the cleaning solution bottle 300 has exhausted, and then MCU module control water pump stop motion, send the prompt tone simultaneously and remind the user to carry out the cleaning solution and supply, perhaps send cleaning solution supply information to user's app end. Wherein, probe level gauge, MCU module and water pump can refer to prior art, and this no longer gives details here.

The base station a will be described in detail below with reference to specific application scenarios.

Application scenario one (taking surface cleaning equipment as a sweeping robot as an example)

And after receiving the cleaning equipment, the user C pairs the base station A and the sweeping robot according to the requirements of the specification, and downloads a client from the mobile phone, so that the mobile phone is linked with the cleaning equipment.

Next, the user c places the base station a on the floor of the living room, opens the upper cover at the top of the base station a, sequentially mounts the clean water tank, the sewage tank and the cleaning liquid bottle 300 to the corresponding mounting positions in the accommodating chamber 110 through the placing port 130, and fills the clean water tank with clean water, thereby completing the mounting of the base station a.

Then, the user tries the cleaning route set by the sweeping robot, and the sweeping robot cleans the ground according to the set cleaning route. When the sweeping robot finishes sweeping according to the set cleaning route, the sweeping robot automatically returns to the base station A and enters the cleaning area of the base station A, and the base station A charges the sweeping robot. Meanwhile, the clean water tank provides clean water to the cleaning area through the diversion assembly 230, the cleaning liquid bottle 300 provides cleaning liquid to the cleaning area through the liquid supply mechanism 400, the clean water and the cleaning liquid are mixed in the second channel 232, and the mixed liquid is upwards sprayed from the bottom of the cleaning area, so that the rolling brush of the sweeping robot is washed. After the base station A finishes cleaning the rolling brush, the backflow assembly extracts sewage generated in a cleaning area into the sewage tank to be collected, and therefore automatic cleaning of the sweeping robot is achieved.

After the trial is finished, the user is rather satisfied with the use effect of the cleaning equipment. Therefore, the user sets the cleaning route and the daily cleaning time of the sweeping robot again, and puts the cleaning equipment into use formally.

With the day-to-day cleaning work of the cleaning equipment, in the early morning of a certain day, the user discovers that the mobile phone client displays a message prompt about the fact that the cleaning solution is exhausted and needs to be replenished. Then, the user opens the upper lid of the base station a again and finds that the cleaning liquid in the cleaning liquid bottle 300 has been exhausted. Subsequently, the user detaches the cleaning liquid bottle 300 depleted of the cleaning liquid and installs the cleaning liquid bottle 300, which is attached and not used when purchasing the cleaning device, into the accommodating chamber 110. After the user finishes replacing the cleaning liquid bottle 300, the base station a detects that the liquid level of the cleaning liquid in the liquid storage cavity 412 is normal through the self-checking program, and the base station a returns to normal operation.

Therefore, according to the technical scheme, the base station is provided with the containing cavity and the cleaning area, wherein the containing cavity is internally provided with the upper water module and the lower water module and the cleaning liquid bottle, the upper water module and the lower water module are communicated with the cleaning area, and the cleaning liquid bottle is communicated with the cleaning area through the liquid supply mechanism. When the surface cleaning device is positioned in the cleaning area, the water feeding and discharging module can spray clean water to the cleaning part of the surface cleaning device, and the liquid supply mechanism can guide the cleaning liquid in the cleaning liquid bottle to the cleaning part, so that the cleaning part is cleaned. In the scheme of this application, cleaning solution and clear water hold respectively in the container of difference, and the user need not in advance to mix cleaning solution and clear water in same container, and this also makes the user when replenishing the clear water to the clear water tank, need not to replenish, allocate the cleaning solution again, has alleviateed the burden when user's use equipment. Simultaneously, the basic station is provided with places the mouth, and water module and clean liquid bottle can fix in the holding intracavity through should placing the mouth in the upper and lower water module, so, the user can directly carry out the dismouting to the clean liquid bottle through placing the mouth to clean liquid bottle and water module can not take place to interfere, easy dismounting about the in-process of dismouting. In addition, the projection of the cleaning liquid bottle on the plane where the placing port is located is partially overlapped with the placing port, namely, the mounting position of the cleaning liquid bottle is located in the covering range of the placing port, so that an outward protruding cavity used for storing the cleaning liquid bottle is not required to be additionally arranged on the side wall of the base station, and the cleaning liquid bottle enables the overall structure of the base station to be simpler. Furthermore, because the upper and lower water modules and the cleaning liquid bottle are arranged in the same accommodating cavity, when a user replaces and replenishes any one of the cleaning liquid bottle and the upper and lower water modules, the user can observe the working states of the cleaning liquid bottle and the upper and lower water modules simultaneously, and the working reliability of the base station is improved.

Further, the cleaning liquid bottle is communicated with the cleaning area through a liquid supply mechanism, the liquid supply mechanism can be composed of a liquid storage box, a liquid guide pipe and a liquid drawing device, the liquid storage box is provided with air holes and a liquid storage cavity, and the liquid storage cavity is communicated with the outside air through the air holes.
