Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings. The use of terms herein such as "upper," "lower," "below," "first end," "second end," "one end," "another end," and the like, to denote relative spatial positions, is for convenience of description to describe one element or feature's relationship to another element or feature as illustrated in the figures. The spatially relative positional terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

Furthermore, the terms "mounted", "disposed", "provided", "connected", "slidably connected", "fixed" and "sleeved" are to be understood in a broad sense. For example, "connected" may be a fixed connection, a detachable connection, or a unitary construction; can be a mechanical connection, or an electrical connection; may be directly connected, or indirectly connected through intervening media, or may be in internal communication between two devices, elements or components. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.

With the improvement of living standard of people, more and more families begin to reduce labor intensity and improve life quality by means of various cleaning devices, such as floor washers, carpet washers and the like. Taking a floor washing machine as an example, most floor washing machines on the market currently have a solution barrel, a mixture of clean water and detergent is contained in the solution barrel, the floor washing machine supplies the clean water and the detergent to a rolling brush through a liquid loop inside a machine body, the rolling brush cleans the ground by using the clean water and the detergent, and meanwhile, the floor washing machine sucks sewage into a sewage tank, so that a cleaning process is completed.

However, the filling port of the existing solution barrel is fixed and cannot be extended. In some scenarios, for example when the faucet of the wash stand is too short, it is difficult for the user to fill the solution tank with fresh water. Even if the user injects the clear water by adjusting the angle of the solution barrel, the solution barrel cannot be completely filled in order to avoid the clear water from spilling out of the solution barrel, and the capacity of the solution barrel cannot be completely utilized, so that the user needs to frequently stop to add water, and the cleaning efficiency of the floor cleaning machine is finally affected. Meanwhile, due to the structural limitation of the solution barrel, the diameter of the filling opening cannot be too large, so that when a user injects clean water into the solution barrel, the clean water is often sprinkled on the washing table or the solution barrel, and the leaked liquid easily corrodes a label or an organism, so that the user has to additionally wipe the washing table or the solution barrel. The above-mentioned drawbacks greatly affect the user's feeling of use.

Therefore, how to improve the structure of the solution barrel to solve the problem of inconvenient water injection of the solution barrel becomes a problem to be solved 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 a part of the embodiments of the present application, and not all embodiments. 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 7 together, in an implementable embodiment, the cleaning apparatus includes at least a solution bucket 1 and a machine body 2, wherein the machine body 2 has a mounting location (not shown) through which the solution bucket 1 is connected with the machine body 2. In practical applications, the body 2 is provided with a liquid passage (not shown) inside, which can supply the cleaning liquid in the solution tank 1 to a cleaning assembly (such as a rolling brush assembly or a dishcloth disc, etc.) for the cleaning assembly to clean the floor. Specifically, a liquid inlet (not shown) is provided at the mounting position of the machine body 2, a liquid outlet 11 is provided at the solution barrel 1, and when the solution barrel 1 is connected to the machine body 2 through the mounting position, the liquid outlet 11 at the solution barrel 1 can be in butt joint with the liquid inlet, so that the solution barrel 1 is communicated with the liquid passage inside the machine body 2. It should be noted that the specific form of the cleaning device may be a floor cleaning machine, a carpet cleaning machine, etc., and the solution bucket 1 may be externally hung on the sidewall of the machine body 2, may be internally disposed inside the machine body 2, or may be disposed at the top end of the machine body 2 according to the specific structure of the cleaning device, and the application does not limit the placement position of the solution bucket 1.

In the present embodiment, the solution barrel 1 has a filling port 12, a solution chamber 13 and a telescopic tube assembly 14, wherein a hole may be opened on a barrel wall of the solution barrel 1 to form the filling port 12, the telescopic tube assembly 14 is inserted into the solution chamber 13 through the filling port 12, and the telescopic tube assembly 14 is communicated with the solution chamber 13, so that a user may fill liquid into the solution chamber 13 through the telescopic tube assembly 14. The extension tube assembly 14 is removably coupled to the fill port 12, and in particular, the extension tube assembly 14 and the fill port 12 can be coupled together by threads, snap fit, or the like. When the extension tube assembly 14 is coupled to the fill port 12, most of the structure of the extension tube assembly 14 is located inside the solution chamber 13. Further, when the user detaches the extension tube assembly 14 from the fill port 12, thereby disengaging the extension tube assembly 14 from the fill port 12, the extension tube assembly 14 may be moved between the extended position and the retracted position within the solution chamber 13 under the influence of an external force (e.g., the user pulls the extension tube assembly 14 with a hand). Wherein the retracted position corresponds to: the position of the extension tube assembly 14 inside the solution chamber 13 when the extension tube assembly 14 is connected to the fill port 12. The extended position corresponds to: the position of the extension tube assembly 14 inside the solution chamber 13 is when the entire structure of the extension tube assembly 14 is about to be fully exposed from the fill port 12. The bellows assembly 14 may be an expansion joint of a corrugated compensator, a sleeve compensator, a rotary compensator, a square compensator, or a pipe such as a corrugated pipe or a rubber hose.

In practice, when a user needs to fill the solution tank 1 with a liquid, the user can remove the extension tube assembly 14 from the fill port 12 and then pull the extension tube assembly 14 such that the extension tube assembly 14 moves away from the retracted position. As the user continues to pull on the extension tube assembly 14, the structure of the extension tube assembly 14 will gradually emerge from the fill port 12. When the entire structure of the extension tube assembly 14 is about to be completely exposed from the fill port 12, the extension tube assembly 14 is now in the extended position inside the solution chamber 13. The telescopic tube assembly 14 exposed out of the filling port 12 is equivalent to the length of the filling port 12 being prolonged, so that a user can conveniently fill the solution cavity 13 with the liquid through the telescopic tube assembly 14. When the user has filled the liquid, the user can push the exposed extension tube assembly 14 back inside the solution chamber 13, the extension tube assembly 14 will move from the extended position back to the retracted position, and the user can then re-secure the extension tube assembly 14 to the fill port 12 for the next use.

It should be noted in particular that since the wall thickness of the solution tank 1 is usually between 0.2mm and 2mm, the thickness of the fill port 12 is usually negligible, and the position of the fill port 12 on the solution tank 1 can also be regarded as the extended position. In other words, movement of the extension tube assembly 14 between an extended position within the solution chamber 13 and a retracted position, it is also understood that the extension tube assembly 14 moves between the fill port 12 and the retracted position within the solution chamber 13.

In one realizable embodiment, the extension tube assembly 14 includes a connection ring 141 and a bellows 142, wherein the diameter of the bellows 142 is less than the diameter of the fill port 12, such that the bellows 142 can either extend from the interior of the drip chamber 13 through the fill port 12 or retract back into the interior of the drip chamber 13 through the fill port 12. For ease of understanding, the present application provides for the extension tube assembly 14 to have an up-down orientation. Specifically, the direction indicated by an arrow in fig. 5 is defined as upward, and correspondingly, the direction opposite to the arrow is defined as downward. When defining the up and down orientation of the extension tube assembly 14, the up and down orientation of the extension tube 142, collar 141, etc. is determined with reference to the direction indicated by the arrow in fig. 5.

In practical applications, the outer contour of the connection ring 141 can match the shape of the filling port 12, so that the connection ring 141 can be clamped on the filling port 12. Meanwhile, the upper end of the extension tube 142 can be connected with the lower end of the connection ring 141, for example, the upper end of the extension tube 142 and the lower end of the connection ring 141 are connected into a whole in a threaded connection manner, so that the extension tube 142 can be clamped on the filling opening 12 through the connection ring 141. It should be noted that the telescopic tube 142 may be a tube having a telescopic characteristic, such as a helical bellows tube or a circular bellows tube, or a tube having no telescopic characteristic, such as a universal bamboo joint tube.

In an implementation embodiment, a mutually matched clamping block 121 and a clamping groove 1411 are arranged between the connecting ring 141 and the filling port 12, and the clamping block 121 is rotatably matched in the clamping groove 1411 so that the connecting ring 141 is clamped with the filling port 12. In practical applications, the retaining groove 1411 may be provided on the outer peripheral wall of the connection ring 141, the retaining block 121 may be provided on the inner peripheral wall of the fill port 12, and the retaining block 121 may be rotatably fitted in the retaining groove 1411. Specifically, the clamping groove 1411 may be an L-shaped clamping groove, the L-shaped clamping groove is provided with an open end, the clamping block 121 may enter the inside of the clamping groove 1411 through the open end, and when the user rotates the connection ring 141, the clamping block 121 may slide inside the clamping groove 1411. In another practical embodiment, the catching groove 1411 may be provided on the inner peripheral wall of the fill port 12, and in this case, the catching block 121 may be provided on the outer peripheral wall of the connection ring 141. The connection ring 141 can be engaged with the fill port 12 by engaging the engagement piece 121 with the engagement groove 1411.

Further, two clamping grooves 1411 can be symmetrically formed in the outer peripheral wall of the connecting ring 141, correspondingly, two clamping blocks 121 can be symmetrically formed in the inner peripheral wall of the filling port 12, and by arranging two groups of clamping positions, the connection stability of the connecting ring 141 and the filling port 12 can be further improved, and the connecting ring 141 is prevented from falling off from the filling port 12 accidentally.

It should be particularly noted that the connection ring 141 and the filling port 12 may also be fixed together by a tab projection structure, a thread locking structure, and the like, and the connection mode between the connection ring 141 and the filling port 12 is not limited in the present application.

To facilitate the user pushing and pulling the extension tube assembly 14, in one realizable embodiment, the end of the coupling ring 141 not connected to the extension tube 142, i.e., the upper end of the coupling ring 141, is provided with an annular ledge 1412. In practice, the annular lug 1412 may extend outwardly in a radial direction of the connection ring 141 while the annular lug 1412 extends upwardly in an axial direction of the connection ring 141 to form a trumpet-like structure, and the diameter of the annular lug 1412 is larger than that of the fill port 12. The annular ledge 1412 may increase the gripping area of the user's hand, facilitating the use of the hand-pushed stretch-shrink tubing assembly 14 by the user. Meanwhile, the diameter of the annular lug 1412 is larger than the diameter of the fill port 12, so that when the connection ring 141 and the fill port 12 are engaged, the annular lug 1412 is also engaged over the fill port 12, and the annular lug 1412 prevents the connection ring 141 from being unintentionally disengaged from the fill port 12.

It should be particularly noted that if a portion of the structure (referred to as structure a) of the annular lug 1412 can contact the interior wall of the fill port 12 when the annular lug 1412 snaps over the fill port 12, the snap-in groove 1411 can also be provided in the structure a to facilitate alignment of the snap-in groove 1411 with the snap-in block 121 by a user.

In an achievable embodiment, as shown in fig. 6, the solution tank 1 has a chamfer α on which the filling spout 12 is located. In this scenario, when the connection ring 141 is engaged with the filling port 12, the filling port 12 will have the same inclination angle as the oblique plane α, which means that the gravity line of the telescopic tube 142 is not aligned with the central axis of the filling port 12, and under the action of the self gravity of the telescopic tube 142, the position where the telescopic tube 142 is connected with the connection ring 141 will continuously receive the downward bending force, and the telescopic tube 142 is easily broken at this position.

To solve the above problem, a transition section 1413 may be provided at the lower end of the connection ring 141, the transition section 1413 extending downward in the axial direction of the connection ring 1413 while the transition section 1413 is bent to deviate from the axial direction of the connection ring 1413 to form a break angle θ. The bend angle θ is configured such that: when the upper end of the bellows 142 is connected to the transition section 1413, the bellows 142 is suspended in the solution chamber 13 in a vertical state. In practical applications, the fold angle θ depends on the inclination angle of the chamfer α, and specifically, the sum of the fold angle θ and the inclination angle of the chamfer α is 180 °.

In an implementation manner, in order to improve the aesthetic property of the solution tank 1 and facilitate the user to observe the liquid level of the liquid in the solution tank 1, the tank body of the solution tank 1 may be made translucent. For example, the body of the solution tank 1 may be made translucent in a coffee color or translucent in an ink color by adjusting the formulation of the injection molding material. Of course, when the barrel body of the solution barrel 1 is manufactured, it may be manufactured to be completely transparent or completely opaque.

In practical applications, since the bellows 142 is suspended inside the solution chamber 13, the bellows 142 can swing back and forth in the solution chamber 13 along with the swing of the solution bucket 1, and meanwhile, since the bellows 142 has a certain length, if the bellows 142 naturally hangs down inside the solution chamber 13, a user can directly see the hanging bellows 142 through the transparent bucket wall, which is not good for the user's sense. To solve the above problem, as shown in fig. 6, in an realizable embodiment, a limiting portion 131 may be provided inside the solution chamber 13, while a limiting support ring 143 is provided in the telescopic tube assembly 14. Specifically, the limiting support ring 143 is connected to the lower end of the telescopic tube 142, the limiting support ring 143 is sleeved on the outer peripheral wall of the telescopic tube 142, and the limiting portion 131 may be a baffle plate disposed inside the solution chamber 13, or may also serve as the limiting portion 131 by using a reinforcing rib inside the solution chamber 13. The distance from the stopper 131 to the filling port 12 is equal to or less than the natural extension length of the bellows 142, so that the stopper support ring 143 abuts against the stopper 131 when the bellows 142 is positioned inside the solution chamber 13. The stopper 131 may support the stopper support ring 143 to compress and fix the bellows 142 inside the solution chamber 13, thereby preventing the bellows 142 from swinging back and forth in the solution chamber 13. Meanwhile, the telescopic tube 142 is in a contracted state when being retracted, and a user cannot see the telescopic tube 142 under the shielding of the outer covering part of the barrel cover, so that the liquid barrel 1 can be more attractive.

Regarding the specific structure of the limiting portion 131, two possible embodiments are provided for reference in the present application.

In the first embodiment, a diaphragm having a honeycomb-like opening is provided as the stopper 131 in the interior of the solution chamber 13, and the fixed position of the diaphragm corresponds to the retracted position of the telescopic tube assembly 14 so that the stopper support ring 143 is just abutted against the diaphragm when the connection ring 141 is engaged with the filler port 12. The diaphragm plate can support the limiting support ring 143 to prevent the telescopic tube 142 from shaking, and the honeycomb-shaped holes on the diaphragm plate can also ensure the normal flow of liquid in the telescopic tube 142.

Further, the diameter of the limit support ring 143 is larger than the diameter of the filling opening 12, so that when a user pulls the telescopic tube 142, the lower end of the telescopic tube 142 is clamped by the filling opening 12 even if the lower end of the telescopic tube 142 is pulled to the filling opening 12, thereby ensuring that the telescopic tube 142 cannot fall off from the filling opening 12.

In the second embodiment, two diaphragms are vertically provided in the solution chamber 13, and the two diaphragms together constitute the stopper 131. A gap is left between the upper and lower layers of diaphragm plates, and the size of the gap is set according to the thickness of the limiting support ring 143, so that the limiting support ring 143 can be clamped in the gap. Meanwhile, the upper and lower layers of diaphragm plates are both provided with a round hole, the central axes of the two round holes are superposed, and the diameters of the two round holes are larger than that of the telescopic tube 142 and smaller than that of the limiting support ring 143. The above structure can fix the limit support ring 143 between the upper and lower diaphragms to prevent the telescopic tube 142 from shaking, and meanwhile, the liquid in the telescopic tube 142 can flow normally through the two circular holes.

It should be noted that, in the present embodiment, the limiting support ring 143 is limited in the gap between the upper and lower diaphragms, so that when the user pulls the bellows 142, the lower end of the bellows 142 is limited and kept still, and the extension and retraction of the bellows 142 is realized by the telescopic performance of the bellows 142 itself. Therefore, in the present embodiment, the bellows 142 must have a telescopic performance.

In an implementation embodiment, please refer to fig. 2, fig. 3, and fig. 4 together, the solution barrel 1 is further provided with a solution barrel cover 15, the solution barrel cover 15 is provided with an overturning connection portion 151, and the solution barrel cover 15 is connected to the filling port 12 in an overturning manner through the overturning connection portion 151. Specifically, an insertion hole 122 is provided in the vicinity of the fill inlet 12, the flip-over connection portion 151 is inserted into the insertion hole 122, and the flip-over connection portion 151 can rotate in the insertion hole 122. When the flip-up connection 151 is rotated in the receptacle 122, the solution barrel cover 15 can be flipped over to open or close the fill port 12. It should be noted that the solution barrel cover 15 may also be connected to the filling port 12 by means of pin holes or hinges, as long as the connection can be turned on or off the solution barrel cover 15 on the filling port 12.

To improve the sealing effect of the solution tank cover 15 on the filling port 12, in an achievable embodiment, a locking ring 152 is provided on a side of the solution tank cover 15 facing the filling port 12, specifically, the locking ring 152 is configured as a cylindrical structure, and the diameter of the locking ring 152 is slightly smaller than that of the filling port 12. When the solution tank cover 15 closes the fill port 12, the locking ring 152 can interface with the fill port 12, and the locking ring 152 is at least partially located inside the fill port 12, the locking ring 152 can increase the sealing of the solution tank cover 15 to the fill port 12.

Furthermore, the locking ring 152 is provided with a plurality of vent holes 1521, so that when the solution barrel cover 15 closes the filling opening 12, air in the solution cavity 13 can overflow from the vent holes 1521. Meanwhile, when the solution tank cover 15 is turned over to open the fill port 12, the outside air can flow into the inside of the solution chamber 13 from the above-mentioned vent hole 1521. The vent hole 1521 may equalize the pressure difference between the solution chamber 13 and the outside air, thereby allowing a user to open and close the fill port 12 more smoothly.

In an implementation, an annular groove 1522 may be provided on the outer wall of the locking ring 152, and the sealing ring 153 may be embedded in the annular groove 1522. When the locking ring 152 is engaged with the fill port 12, the sealing ring 153 may engage the inner wall of the fill port 12 to form a sealing surface to better seal the fill port 12 and prevent fluid from leaking out of the solution chamber 13. Alternatively, the sealing ring 153 may be an O-ring rubber sealing ring.

The application also provides a solution barrel 1, the solution barrel 1 at least comprises a solution barrel cover 15, a filling port 12, a solution cavity 13 and a telescopic pipe assembly 14, wherein the solution barrel cover 15 is provided with an overturning connecting part 151, and the solution barrel cover 15 is connected to the filling port 12 in a way of overturning and opening through the overturning connecting part 151; the telescopic pipe assembly 14 is arranged in the solution cavity 13 through the filling port 12, and the telescopic pipe assembly 14 is communicated with the solution cavity 13; the extension tube assembly 14 is removably connected to the fill port 12, and the extension tube assembly 14 is movable between an extended position and a retracted position within the solution chamber 13 when the extension tube assembly 14 is disconnected from the fill port 12.

To enhance the sealing effect of the solution tank cover 15 on the fill port 12, in an achievable embodiment, a locking ring 152 is provided on a side of the solution tank cover 15 facing the fill port 12, in particular, the locking ring 152 is configured as a cylindrical structure, and the diameter of the locking ring 152 is slightly smaller than the diameter of the fill port 12. When the solution tank cover 15 closes the fill port 12, the locking ring 152 can interface with the fill port 12, and the locking ring 152 is at least partially located inside the fill port 12, and the locking ring 152 can increase the sealability of the solution tank cover 15 to the fill port 12.

Meanwhile, when the solution tank cover 15 is turned over to open the fill port 12, the outside air can flow into the inside of the solution chamber 13 from the above-mentioned vent hole 1521. The vent hole 1521 may equalize the pressure difference between the solution chamber 13 and the outside air, thereby allowing a user to open and close the fill port 12 more smoothly.

Further, an annular groove 1522 may be provided on the outer wall of the locking ring 152, and the sealing ring 153 may be embedded in the annular groove 1522.

Alternatively, the sealing ring 153 may be an O-ring rubber sealing ring.

The details of the structure of the solution barrel 1 can be found in the above embodiments, and are not described herein.

It should be noted in particular that the solution tank 1 may be installed in a floor cleaning machine, a carpet cleaning machine or other cleaning equipment, so as to provide cleaning solution for a rolling brush or other cleaning component, or may be used as a cleaning water tank in a base station for filling cleaning solution for a floor cleaning robot or other equipment.

The filling process of the solution tank will be described in detail below with reference to a specific application scenario, taking a cleaning device as a floor washing machine as an example.

Application scenario one

Xiaoming carelessly turns over the soy sauce on the floor, and takes out the floor washing machine to clean the floor when he is busy. When the floor cleaning machine is started, the floor cleaning machine gives out a voice prompt: the solution barrel is lack of water. When the semitransparent barrel body is observed, only a little liquid is left in the solution barrel, so that the floor washing machine is pushed to the position near the washing table by the naked eye, then the solution barrel is detached from the floor washing machine, and the solution barrel is ready to be filled with clear water.

The washing table is too high, and the solution barrel cannot be vertically placed below the water faucet, so that water receiving is inconvenient.
