Cleaning bucket and cleaner

Abstract

The present invention provides a cleaning bucket. The outer bucket (1) remains stationary, and the inner bucket (2) is driven to rotate by a manual crank operating structure. The rotation of the inner bucket (2) enables the extrusion opening (3) of the water squeezing structure to switch between two positions, namely the gap (4) between the outer bucket (1) and the inner bucket (2) and the inner bucket (2). At these two positions, the water squeezed out by the water squeezing structure can flow into the inner bucket (2) through the guiding structure. The extrusion opening (3) is fixedly installed with an integrated extrusion and cleaning member, which includes an extrusion part (6) and a cleaning part (34). The extrusion part (6) and the cleaning part (34) are integrally arranged up and down. An elastic part (35) for supporting the swing of the extrusion part (6) is provided between the extrusion part (6) and the cleaning part (34). The relative positions of the cleaning area and the squeezing area can be changed. The integrated design of the extrusion and cleaning member improves consistency and significantly reduces costs. A cleaner with this cleaning bucket is also provided.

Description

Technical Field

[0001] The invention relates to the technical field of mop cleaning structures, in particular to a cleaning bucket and a cleaning device. Background Art

[0002] In the prior art, a washing bucket used for a flatbed trailer is provided with a washing area and a squeezing area in order to achieve the two purposes of washing and squeezing out. The washing area and the squeezing out area are separated by a partition. In order to be able to use the squeezing structure during washing and squeezing out, the prior art proposes three solutions: the first is to respectively set a squeezing structure in the washing area and the squeezing out area; the second is to share a squeezing structure, which can be switched between the washing area and the squeezing out area; the third is more special, in which the washing area is also used as a water storage area, and the main feature is that a first water guide structure is provided between the washing area and the squeezing out area, and only the squeezing out area is provided with a squeezing structure, and a second water guide structure is provided between the washing area and the squeezing structure. When the third method is used, the user controls the first water guide structure to move the water in the washing area A squeezing area is introduced, so that there is a certain amount of water in the squeezing area. When the flat plate is reciprocated in the squeezing structure, it also reciprocates in the squeezing area. This reciprocating motion process makes the flat plate immersed in the certain amount of water. Multiple reciprocating motions achieve a cleaning purpose. At the same time, each time it is pulled out, the water is guided back to the cleaning area through the second water guide structure under the action of the squeezing structure. This is why the cleaning area is also used as a water storage area. Then, after multiple pulling and drawing, the certain amount of water is basically drawn back to the cleaning area, and then pulling and drawing can achieve the purpose of squeezing out. In this way, the purpose of using the squeezing structure for both cleaning and squeezing out is achieved. Of course, the third structure can also directly put the flat plate into the cleaning area for cleaning, but the squeezing structure is not used for cleaning at this time.

[0003] Therefore, the water squeezing structure is the core component of the flatbed carriage cleaning and squeezing.

[0004] In order to facilitate the understanding of the present application, the water squeezing structure is further explained. Some people in the water squeezing structure industry also call it a stroking structure. The user holds the flat mop and makes the flat mop and the water squeezing structure move relative to each other. The water squeezing structure squeezes water from the flat mop, thereby achieving a squeezing effect. This squeezing does not mean that the water can be completely squeezed out, but most of the water can be squeezed out, and the flat mop still has a certain humidity.

[0005] The squeezing structure can be used for squeezing out water or for cleaning. Specifically, when squeezing out water, the flat mop is squeezed out. The operation can be repeated several times to achieve the purpose of squeezing out water. The squeezing out water does not mean that the flat mop can be completely squeezed out, but most of the water can be squeezed out. The flat mop still has a certain humidity. When used for cleaning, it is immersed in water, repeatedly wetted and squeezed out, so as to achieve the purpose of cleaning. The realization of this function only requires providing an environment for immersion in water, such as a container containing water, a pool, or even a pond or a river.

[0006] As can be seen from the above, the cleaning area and the wringing area of the cleaning bucket are relatively fixed without relative position transformation. However, this application aims to explore a new path and propose a new technical route to break away from the above three technical solutions.

[0007] There is also a problem in the prior art. Currently, there is a water wringing structure that can achieve two functions of water wringing and cleaning. The water wringing and cleaning are realized by two components. The water wringing is mainly through the squeezing member, and the cleaning is mainly through the cleaning brush. The two components are respectively installed at the squeezing opening. Since they are two components and need to be installed in two steps, it is difficult to control the installation accuracy. For example, for the relative position relationship between the two components, due to production errors and installation errors, it is difficult to ensure the consistency of the relative position relationship between the two components. Especially in mass production, the differences in the technical parameter of the relative position relationship between the two components among various water wringing structures are relatively large, which is not conducive to ensuring the consistency of the performance of each water wringing structure. In addition, since they are two components and need to be installed in two steps, the production and assembly are both relatively complex and have high requirements, significantly increasing the cost. Moreover, even with a lot of cost spent, the consistency may not necessarily be improved. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a cleaning bucket in which the relative positions of the cleaning area and the wringing area can be transformed, the squeezing and cleaning member is integrally designed to improve consistency and significantly reduce costs; and also provide a cleaner having such a cleaning bucket.

[0009] To solve the above technical problems, the present invention provides a cleaning bucket, which includes a water wringing structure, and also includes an outer bucket, an inner bucket and a manual rotary handle operating structure. The outer bucket is sleeved with the inner bucket. The outer bucket is stationary, and the inner bucket is driven to rotate by the manual rotary handle operating structure. The outer bucket is fixedly installed with the water wringing structure. The rotation of the inner bucket can switch the squeezing opening of the water wringing structure between two positions, namely the interval between the outer bucket and the inner bucket and the inner bucket. At these two positions, the water squeezed out by the water wringing structure can flow into the inner bucket through the guiding structure; a squeezing and cleaning member with an integrated structure is fixedly installed at the squeezing opening. The squeezing and cleaning member includes a squeezing part and a cleaning part. The squeezing part and the cleaning part are integrally arranged up and down, and an elastic part for supporting the swinging of the squeezing part is provided between the squeezing part and the cleaning part.

[0010] After adopting the above structure, compared with the prior art, the present invention has the following advantages: The outer barrel is sleeved with the inner barrel. The outer barrel remains stationary, and the inner barrel is driven to rotate by a manual crank operation structure. The outer barrel is fixedly installed with the water squeezing structure. When the inner barrel rotates, the extrusion opening of the water squeezing structure can be switched between two positions, namely the interval between the outer barrel and the inner barrel and the inner barrel. Since the inner and outer barrels are isolated from each other, the interval and the inner barrel belong to two isolated areas. Therefore, by realizing the switching between the two positions, a cleaning area and a squeezing area can be provided, and a single water squeezing structure is shared. Therefore, compared with the prior art, this solution is the fourth technical solution. In addition, in the present application, since the inner and outer barrels are sleeved, the space utilization rate can be higher. In this solution, the inner barrel generally serves as the cleaning area, and the interval serves as the squeezing area. This is because the cleaning area requires more space to hold water. With such a design, the structure can be made more compact, and it is also convenient to arrange the water squeezing structure. At the same time, the extrusion and cleaning are integrated. Whether in production or assembly, it is easy to control the accuracy, improve the consistency of the cleaning barrel performance, simplify the production and assembly, and significantly reduce the cost of the cleaning barrel. In addition, the elastic part is used to support the swinging of the extrusion part, which can realize the swinging of the extrusion part, change the horizontal extrusion distance of the extrusion opening, and achieve better water squeezing performance.

[0011] As an improvement, the elastic part includes an upper part, an elastic bent part, and a lower part arranged in sequence. The upper part is connected to the extrusion part, and the lower part is connected to the cleaning part. In this way, the structure is simple and the performance is stable and reliable.

[0012] As an improvement, the upper part, the elastic bent part, and the lower part form a forward-bending arc body. The upper part is connected to the rear end of the extrusion part, and the lower part is connected to the rear end of the cleaning part. In this way, the structure is simple and the performance is stable and reliable.

[0013] As an improvement, the lower part is provided with a support part, and the upper end of the support part extends to the rear of the elastic bent part. In this way, on the one hand, the support part can be used to stabilize the rear of the elastic bent part, control the elastic deformation to occur in the bending part of the elastic bent part, and further ensure that the swinging of the extrusion part meets the requirement of changing the horizontal extrusion distance. In other words, this improvement controls the swinging situation through a simple structural setting. On the other hand, it strengthens the elastic bent part and improves the reliability of the elastic bent part.

[0014] As an improvement, the elastic part is one or more and is arranged along the length direction of the extrusion part. In this way, it can be flexibly set to provide reliable elastic swinging support.

[0015] As an improvement, a support part is provided between the extrusion part and the cleaning part; the extrusion part is connected to the support part, and there is a gap between the support part and the cleaning part, or the cleaning part is connected to the support part, and there is a gap between the support part and the extrusion part; the said gap serves as the swinging space of the extrusion part. In this way, on the one hand, the degree of swinging is controlled, so as to ensure that the swinging of the extrusion part meets the requirement of changing the horizontal extrusion distance, and on the other hand, it is used to support the extrusion part, significantly reducing the deformation of the extrusion part under the action of the flat mop.

[0016] As an improvement, the extrusion part is a plate-shaped body with a front end higher than the rear end. The front edge of the plate-shaped body is a narrow end, and the narrow end is arranged in an arc shape. The rear part of the plate-shaped body is a cuboid part with a gradually decreasing thickness from front to back; in the initial state, the front edge protrudes forward in the horizontal direction compared with the cleaning part. In this way, it is more conducive to water squeezing and improving the cleaning performance.

[0017] As an improvement, the cleaning part includes a brush plate and brush teeth. The brush teeth are convex bodies protruding forward from the brush plate; the brush plate is provided with a connecting structure, and this connecting structure is used to install the extrusion and cleaning part in the water squeezing structure. In this way, the structure is reasonable, has good strength, and is convenient for connection.

[0018] As an improvement, the connecting structure includes connecting parts respectively arranged at the left and right ends of the brush plate. The said connecting parts are fixedly connected to the water squeezing structure. In this way, the structure is reasonable, has good strength, and is convenient for connection.

[0019] As an improvement, the brush teeth are cylinders, or cones, or ellipsoidal cylinders, or serrated bodies, or polyhedrons. Each row of brush teeth is arranged in a staggered or corresponding uniform distribution in multiple rows, or is arranged irregularly. In this way, a structure of the cleaning part is provided. When the flat mop is pulled up and down through the cleaning brush at the extrusion opening, the brush teeth comb the cleaning cloth back and forth, so as to obtain an efficient scale removal and cleaning effect.

[0020] As an improvement, the connecting part includes mating protrusions provided at the left and right ends of the brush plate. First holes for mating with the mating protrusions are provided on both left and right side surfaces of the extrusion opening. The first holes communicate with the lower part of the extrusion opening through first slots arranged in the up and down direction. In this way, the structure is simple, convenient for assembly, has a relatively high assembly accuracy, and reduces costs.

[0021] As an improvement, both the left and right ends of the brush plate protrude from the left and right ends of the extrusion part. Both the left and right ends of the brush plate are fixedly connected to the corresponding side surfaces of the extrusion opening. The end surfaces of the left and right ends of the extrusion part are in clearance fit with the corresponding side surfaces of the extrusion opening. In this way, the structure is reasonable, and the fixation is stable and reliable.

[0022] As an improvement, the extrusion opening includes rollers and guide ribs. The rollers and guide ribs are both arranged on the side of the extrusion opening opposite to the first extrusion part. In this way, the guiding of the insertion and extraction of the flat mop is enhanced, and at the same time, the rollers reduce the resistance of the insertion and extraction, making the operation more labor-saving.

[0023] As an improvement, it further includes a first squeezing member. The first squeezing member and the squeezing and cleaning member are arranged vertically. The leading edge of the first squeezing member retreats from that of the squeezing portion, and the retreating direction is away from the squeezing opening. In this way, the function of the retreat is that it is easier for the squeezing opening to insert into the flat mop board. Meanwhile, with two squeezing members, during the downward insertion of the flat mop, the first squeezing member can squeeze out most of the water, and the second squeezing member can squeeze out a small part of the water, achieving the purpose of double squeezing. The two cooperate with each other vertically, enabling a better water squeezing effect and having the advantage of killing two birds with one stone.

[0024] As an improvement, the guiding structure is a water guiding structure. The water squeezing structure is provided with this water guiding structure. At the two positions mentioned, the water squeezed out by the water squeezing structure can flow into the inner bucket through this water guiding structure. In this way, a preferred solution is provided, with a relatively simple structure, which is beneficial for water collection and water guiding.

[0025] As an improvement, the guiding structure is composed of two water guiding structures, namely the first water guiding structure and the second water guiding structure. The water squeezing structure is provided with the first water guiding structure, and the inner bucket is provided with the second water guiding structure. At the two positions mentioned, the water squeezed out by the water squeezing structure can sequentially flow into the inner bucket through the first water guiding structure and the second water guiding structure. Or at an interval from this position, the water squeezed out by the water squeezing structure can sequentially flow into the inner bucket through the first water guiding structure and the second water guiding structure. And at this position of the inner bucket, the water squeezed out by the water squeezing structure can directly flow into the inner bucket through the first water guiding structure. In this way, a preferred solution including the first water guiding structure and the second water guiding structure is provided. The advantages are that, on the one hand, it provides a basis for setting other structures in the second water guiding structure. For example, a rotating shaft can be set in the second water guiding structure to facilitate the realization of the rotating structure. In this way, there is no need to directly set a rotating shaft on the inner bucket, reducing the complexity of the inner bucket manufacturing and reasonably arranging the relationship between the rotating shaft and the second water guiding structure. Generally speaking, the structure is simple. On the other hand, through the second water guiding structure, the water guiding direction can be made more controllable.

[0026] As an improvement, the first water guiding structure includes a water flow channel provided on the body, as well as the upper surfaces of the first squeezing member and the squeezing portion as the water guiding surfaces. The first squeezing member is also provided with a first water outlet through which the water flowing along the upper surface of the first squeezing member can flow out. The water flowing from the first water outlet and the upper surface of the squeezing portion all converge into the water flow channel. At the two positions mentioned, the outlets of the water flow channel are both connected to the inlets of the second water guiding structure. Or at an interval from this position, the outlet of the water flow channel is connected to the inlet of the second water guiding structure. And at this position of the inner bucket, the outlet of the water flow channel is connected to the inner bucket. In this way, the first water guiding structure utilizes the water squeezing structure to form its own structure, making the overall structure simple and compact, with low cost, and at the same time having good water squeezing and water guiding effects.

[0027] As an improvement, the second water guiding structure is a water guiding box which is provided with an upwardly open mouth. The water flowing out of the water flow channel flows into this mouth, and the mouth serves as the inlet of the second water guiding structure. The lower part of the inner bottom surface of the water guiding box is provided with a second water outlet downward, and the second water outlet serves as the outlet of the second water guiding structure. In this way, a measure for flexibly changing the water flow direction is provided, which is beneficial to water collection and water guiding.

[0028] As an improvement, the manual turning handle operating structure includes a turning handle, a coupling sleeve, and a rotating shaft provided on the second water guiding structure. The outer barrel is provided with a cover which is provided with a shaft hole. The coupling sleeve is rotatably sleeved with the shaft hole. The turning handle, the coupling sleeve, and the rotating shaft are sequentially connected and fixed from top to bottom. In this way, the structure is simple and compact, the assembly is extremely convenient, the assembly efficiency is high, the cost is low, and at the same time, the rotation performance is good.

[0029] As an improvement, the turning handle and the coupling sleeve are connected through a first anti-misassembly structure, and the coupling sleeve and the rotating shaft are connected through a second anti-misassembly structure. In this way, whether in production or during user disassembly and assembly, it will not be misassembled, the assembly is extremely convenient, the assembly efficiency is high, and the cost is low.

[0030] As an improvement, the first anti-misassembly structure includes a triangular jack provided on the coupling sleeve and a triangular plug column provided on the turning handle and matching with the triangular jack. The second anti-misassembly structure includes a jack with a radial protrusion provided on the coupling sleeve and a plug column with a radial protrusion provided on the rotating shaft and matching with the jack with the radial protrusion. In this way, the production is convenient and the cost is low.

[0031] As an improvement, an axial through hole or an axial blind hole is provided in the circumferential direction of the shaft hole; when it is an axial through hole, an elastic member is installed in the axial through hole, and spheres are provided at both ends of the axial through hole. The upper end of the elastic member abuts against the upper sphere, and the lower end of the elastic member abuts against the lower sphere. The upper sphere is in rolling fit with the lower surface of the turning handle and is axially limited by this lower surface. The lower sphere is in rolling fit with the upper surface of the circumferential part at the lower end of the coupling sleeve and is axially limited by this upper surface; when it is an axial blind hole, an elastic member is installed in the axial blind hole, and a sphere is provided at the open end of the axial blind hole. When the open end faces downward, one end of the elastic member abuts against the bottom of the axial blind hole, and the other end of the elastic member abuts against the lower sphere. The lower sphere is in rolling fit with the upper surface of the circumferential part at the lower end of the coupling sleeve and is axially limited by this upper surface. Or, when the open end faces upward, one end of the elastic member abuts against the bottom of the axial blind hole, and the other end of the elastic member abuts against the upper sphere. The upper sphere is in rolling fit with the lower surface of the turning handle and is axially limited by this lower surface. In this way, the structure is simple and compact, it will not appear loose after assembly, the assembly is extremely convenient, the assembly efficiency is high, the cost is low, and at the same time, the rolling fit makes the rotation resistance be rolling friction, the rotation is more relaxed and smooth, the use experience is better, and it provides an improved basis for positioning. For example, positioning depressions can be provided on the lower surface or the upper surface or both the upper and lower surfaces. As the turning handle rotates, the spheres enter the positioning depressions, and thus rotational positioning can be achieved.

[0032] As an improvement, a positioning recess is provided on the lower surface of the rotary handle. The positioning recess can cooperate with the upper sphere to achieve circumferential positioning; alternatively, a positioning recess is provided on the upper surface of the circumferential portion at the lower end of the coupling sleeve. The positioning recess can cooperate with the lower sphere to achieve circumferential positioning. In this way, at least two circumferential positioning structures for the inner and outer barrels are provided, which can position the inner and outer barrels at corresponding positions. After positioning, the inner and outer barrels are not prone to shaking. For example, a positioning recess is provided on the lower surface of the rotary handle. When rotation is required, an external force is applied to the rotary handle to make it rotate. In this way, the recess rotates with the rotary handle, the upper sphere rolls out of the recess, and the recess is separated from the upper sphere. When repositioning is required, the rotary handle is rotated to make the upper sphere roll into the recess, thereby achieving positioning.

[0033] As an improvement, the water squeezing structure and the first water guiding structure are both provided on the cover. In this way, the structure is further simplified, the structural compactness is provided, and the cost is low.

[0034] As an improvement, a second elastic block is provided on the inner bottom surface of the inner barrel, and an elastic block mounting seat is provided on the outside of the inner barrel. The elastic block mounting seat is provided with a first elastic block, and the first elastic block is located within the interval. In this way, after the above treatment, there is no need to consider the distance between the two bottom surfaces of the inner and outer barrels and the interference problem of rotation for setting the first elastic block, which can facilitate the setting of the rotating structure and make the structure between the inner and outer barrels more compact. In addition, after such a design, although the interval is changing, the first elastic block can change synchronously, so that the first elastic block can always be located within the interval.

[0035] As an improvement, the inner barrel includes three pieces distributed circumferentially. One of them can be called the main body, and the two pieces on both sides of the main body can be called two wing parts. These three pieces are interconnected. This is beneficial to controlling the influence of eccentricity and reducing the operating resistance of the rotary handle.

[0036] As an improvement, the outer barrel is provided with a rotation fitting column, and the inner barrel is provided with a rotation fitting sleeve. The rotation fitting column and the rotation fitting sleeve are rotatably sleeved. A first stop block is provided circumferentially on the inner surface of the rotation fitting sleeve, and a second stop block is provided circumferentially on the outer surface of the rotation fitting column. An empty groove is formed between the inner surface and the outer surface for the relative circumferential rotation between the first stop block and the second stop block. The first stop block and the second stop block cooperate to form a circumferential limit structure. This structure is not only simple and compact, but also realizes the circumferential limit of the rotation of the inner barrel. In addition, it prevents the rotational inertia generated by excessive force during the operation of the rotary handle.

[0037] As an improvement, the rotation fitting column and the rotation fitting sleeve can be in a rotatable conical fit. In this way, the assembly has good centering, the axis of the rotation fitting sleeve has a high-precision coaxiality, and it can be quickly disassembled and assembled. It can be injection molded by a mold and has good corrosion resistance.

[0038] As an improvement, the total central angle divided by the first stop block and the second stop block is basically 180 degrees, and the central angle divided by the empty slot is basically 180 degrees. Due to manufacturing errors, it is difficult to achieve equal division of the circumference. Therefore, using basically 180 degrees is sufficient. Of course, it would be better if it can be exactly 180 degrees. After such a setting, a more accurate circumferential limiting effect can be achieved, thus making the rotation positioning of the inner barrel more accurate. In addition, this improvement blocks the rotational inertia of the inner barrel, protects the torsional deformation and damage of the rotating components, and achieves better usage effects and service life.

[0039] As an improvement, the outer barrel is equipped with a cover. The cover is provided with a water inlet and outlet near the edge of the outer barrel. The cover is also provided with a handle. A part of the handle is located outside the water inlet and outlet. On the side of the cover opposite to the side where the water inlet and outlet are located, there is an extrusion port. This water inlet and outlet has three functions: 1. It is convenient for the handle to be taken out from the placement slot provided for the handle on the cover; 2. It is convenient to add water to the inner barrel; 3. There is no need to separately set a drain port, and it is convenient for the dirty water in the inner and outer barrels to gather here and be poured outwards.

[0040] To solve the above technical problems, the present invention also provides a cleaner, including a cleaning barrel and a flat mop. The flat mop can be movably sleeved with the extrusion port of the cleaning barrel.

[0041] After adopting the above structure, compared with the prior art, the present invention has the following advantages: It has a cleaning barrel different from the prior art, proposes a new cleaner, and provides another choice for users. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0067] The present invention will be further described in detail below:

[0068] A cleaning bucket of the present invention includes a water squeezing structure, and also includes an outer barrel 1, an inner barrel 2 and a manual rotary handle operation structure. The outer barrel 1 is sleeved with the inner barrel 2. The outer barrel 1 is fixed, and the inner barrel 2 is driven to rotate by the manual rotary handle operation structure. The outer barrel 1 is installed and fixed with the water squeezing structure. When the inner barrel 2 rotates, the extrusion opening 3 of the water squeezing structure can be switched between two positions, namely the interval 4 between the outer barrel 1 and the inner barrel 2 and the inner barrel 2. At these two positions, the water squeezed out by the water squeezing structure can flow into the inner barrel 2 through the guiding structure.

[0069] A circumferential limiting structure is provided between the inner and outer barrels. The function of the circumferential limiting structure is to prevent the inner barrel from causing torsional deformation and damage to components such as the rotary handle, connecting sleeve and transmission shaft due to excessive rotational inertia. The circumferential limiting structure includes: the outer barrel 1 is provided with a rotating mating column 33, the inner barrel 2 is provided with a rotating mating sleeve 32, the rotating mating column 33 and the rotating mating sleeve 32 are rotatably sleeved. The inner surface of the rotating mating sleeve 32 is circumferentially provided with a first stop block 38, and the outer surface of the rotating mating column 33 is circumferentially provided with a second stop block 39. An empty groove 40 is formed between the inner surface and the outer surface for the relative circumferential rotation between the first stop block 38 and the second stop block 39. The first stop block 38 and the second stop block 39 cooperate to form a circumferential limiting structure.

[0070] The total central angle divided by the first stop block 38 and the second stop block 39 is approximately 180 degrees, and the central angle divided by the empty slot 40 is approximately 180 degrees.

[0071] When the guiding structure is a water guiding structure, the water squeezing structure is provided with this water guiding structure. At the two positions described above, the water squeezed out by the water squeezing structure can flow into the inner barrel 2 through this water guiding structure, that is, the outlet of the water flow channel 7 of the water guiding structure can communicate with the inner barrel 2 at both of the two positions.

[0072] This example mainly describes the case where the guiding structure is two water guiding structures. The two water guiding structures are the first water guiding structure and the second water guiding structure respectively. The water squeezing structure is provided with the first water guiding structure, and the inner barrel 2 is provided with the second water guiding structure. In order to achieve that at the two positions described above, the water squeezed out by the water squeezing structure can flow into the inner barrel 2 through the guiding structure, there are two cases: The first case is that at the two positions described above, the water squeezed out by the water squeezing structure can sequentially flow into the inner barrel 2 through the first water guiding structure and the second water guiding structure. At this time, the outlet of the water flow channel 7 should be able to communicate with the inlet of the second water guiding structure at both of the two positions; or the second case is that at the position of interval 4, the water squeezed out by the water squeezing structure can sequentially flow into the inner barrel 2 through the first water guiding structure and the second water guiding structure. At this time, the outlet of the water flow channel 7 should be able to communicate with the inlet of the second water guiding structure at the position of interval 4, and at the position of the inner barrel 2, the water squeezed out by the water squeezing structure can flow directly into the inner barrel 2 through the first water guiding structure, that is, the outlet of the water flow channel 7 can communicate with the inner barrel 2 at the position of the inner barrel 2. This is the case shown in this example.

[0073] The water squeezing structure includes a first squeezing member 5 and an integrated squeezing and cleaning member arranged vertically to achieve the purpose of double squeezing. As shown in the figure, the first squeezing member 5 and the squeezing and cleaning member are arranged vertically. The front edge of the first squeezing member 5 retreats compared with the front edge of the squeezing part 6, and the retreating direction is away from the squeezing opening 3. The function of the retreat is that it is easier for the squeezing opening 3 to insert the flat mop, and at the same time, a better water squeezing effect can be achieved, which has the advantage of killing two birds with one stone.

[0074] The first water guiding structure includes a water flow channel 7 provided on the body and the upper surfaces of the first squeezing member 5 and the squeezing part 6 as a guiding surface 8. The first squeezing member 5 is also provided with a first water outlet 9 for the water flowing over the upper surface of the first squeezing member 5 to flow out. The upper surface of the first squeezing member 5 is provided with a plurality of grooves along the length direction, and each groove is provided with a first water outlet 9. In this way, the partition between adjacent grooves can be used as a reinforcing rib, thereby improving the strength of the first squeezing member 5.

[0075] The water flowing from the upper surfaces of the first extrusion member 5 and the extrusion portion 6 converges into the water flow channel 7. The water flow channel 7 is a hole. By changing the outlet direction of the hole, the direction of water outflow can be controlled. In this example, it is shown as a rectangular hole arranged in the vertical direction; by changing the relative positional relationship between the outlet of the water flow channel 7 and the inlet of the second water guiding structure, there can be two situations for the water flowing out of the outlet of the water flow channel 7 to enter the inner barrel 2. It can also be said that it is a further refinement of the related structure where the water extruded by the water squeezing structure can flow into the inner barrel 2 through the guiding structure at the two positions mentioned above. Specifically: In the first situation, at the two positions mentioned above, the outlet of the water flow channel 7 is connected to the inlet of the second water guiding structure; or in the second situation, that is, at the position of interval 4, the outlet of the water flow channel 7 is connected to the inlet of the second water guiding structure, and at the position of the inner barrel 2, the outlet of the water flow channel 7 is connected to the inner barrel 2.

[0076] The second water guiding structure is a water guiding box 28. The water guiding box 28 is provided with an upward-opening opening, and the opening serves as the inlet of the second water guiding structure. The inner bottom surface of the water guiding box 28 is set as an inclined surface, and a second water outlet 10 is provided downward at the lower part of the inner bottom surface. The second water outlet 10 serves as the outlet of the second water guiding structure, and the second water outlet 10 is connected to the inner barrel 2.

[0077] The water guiding box 28 is also provided with partitions to divide it into multiple areas. Each area is provided with a second water outlet 10, and the partitions are sequentially distributed along the length direction of the water guiding box. The partitions can play a strengthening role.

[0078] The manual handle operating structure includes a handle 11, a coupling sleeve 12, and a rotating shaft 13 provided on the second water guiding structure. The outer barrel 1 is installed with a cover 14, and the cover 14 is provided with a shaft hole 15. The coupling sleeve 12 is rotatably sleeved with the shaft hole 15, and the handle 11, the coupling sleeve 12, and the rotating shaft 13 are sequentially connected and fixed from top to bottom. The handle 11 and the coupling sleeve 12 are fixed with a self-tapping screw 46. Such a connection has the following functions: 1. Prevent the handle 11 from being pulled out upward; 2. Prevent the coupling sleeve 12 from easily falling down under the elastic force of the elastic member 17; 3. Control the compression amount of the elastic member 17. Of course, the handle 11 and the coupling sleeve 12 can also be fixed through other structures, such as tight fitting, upper and lower clamping, etc.

[0079] The handle 11 and the coupling sleeve 12 are connected through a first anti-fooling structure, and the coupling sleeve 12 and the rotating shaft 13 are connected through a second anti-fooling structure. In this example, the first anti-fooling structure includes a triangular socket 42 provided on the coupling sleeve 12 and a triangular plug 43 provided on the handle 11 that is matched with the triangular socket 42. The second anti-fooling structure includes a socket 44 with a radial protrusion provided on the coupling sleeve 12 and a plug 45 with a radial protrusion provided on the rotating shaft 13 that is matched with the socket 44 with the radial protrusion.

[0080] Axially through holes 16 or axially blind holes are provided circumferentially on the shaft hole 15. In this example, there are two axially through holes 16 arranged symmetrically. When they are axially through holes, elastic members 17 are installed in the axially through holes 16. Spheres 18 are provided at both ends of the axially through holes 16. The upper end of the elastic member 17 abuts against the upper sphere, and the lower end of the elastic member 17 abuts against the lower sphere. The upper sphere is in rolling fit with the lower surface of the rotating handle 11 and is axially limited by this lower surface. The lower sphere is in rolling fit with the upper surface of the circumferential part at the lower end of the coupling sleeve 12 and is axially limited by this upper surface. When they are axially blind holes, due to different orientations, there are two cases. Elastic members 17 are installed in the axially blind holes, and spheres 18 are provided at the open ends of the axially blind holes. When the open end faces downward, one end of the elastic member 17 abuts against the bottom of the axially blind hole, and the other end of the elastic member 17 abuts against the lower sphere. The lower sphere is in rolling fit with the upper surface of the circumferential part at the lower end of the coupling sleeve 12 and is axially limited by this upper surface. Or, when the open end faces upward, one end of the elastic member 17 abuts against the bottom of the axially blind hole, and the other end of the elastic member 17 abuts against the upper sphere. The upper sphere is in rolling fit with the lower surface of the rotating handle 11 and is axially limited by this lower surface. The rolling fit can be provided with rolling tracks, such as annular grooves.

[0081] A positioning depression 41 is provided on the lower surface of the rotating handle 11. The positioning depression 41 is located in the rolling track. The positioning depression 41 can cooperate with the upper sphere to achieve circumferential positioning. This is the structure in this example. Of course, a positioning depression 41 can also be provided on the upper surface of the circumferential part at the lower end of the coupling sleeve 12. The positioning depression 41 can cooperate with the lower sphere to achieve circumferential positioning. The positioning depressions 41 are two circumferentially symmetrically arranged.

[0082] The water squeezing structure and the first water guiding structure are both provided on the cover 14. The cover 14 serves as the main body of the water squeezing structure, as shown specifically in the figure.

[0083] An extrusion and cleaning member is fixedly installed at the extrusion opening 3.

[0084] The extrusion and cleaning member includes an extrusion part 6 and a cleaning part 34. The extrusion part 6 and the cleaning part 34 are integrally arranged up and down. An elastic part 35 for supporting the swinging of the extrusion part 6 is provided between the extrusion part 6 and the cleaning part 34.

[0085] The elastic part 35 includes an upper part 35.1, an elastic bent part 35.2, and a lower part 35.3 arranged in sequence. The upper part 35.1 is connected to the extrusion part 6, and the lower part 35.3 is connected to the cleaning part 34.

[0086] The upper part 35.1, the elastic bent part 35.2, and the lower part 35.3 form a forwardly curved arc body. The upper part 35.1 is connected to the rear end of the extrusion part 6, and the lower part 35.3 is connected to the rear end of the cleaning part 34.

[0087] The lower part 35.3 is provided with a support part 35.4, and the upper end of the support part 35.4 extends to the rear part of the elastic bending part 35.2. The support part 35.4 is a support plate provided in pairs or singly. In this example, it is provided in pairs.

[0088] There is one or more elastic parts 35, which are arranged along the length direction of the extrusion part 6. In this example, there are three.

[0089] A support part 48 is provided between the extrusion part 6 and the cleaning part 34; the extrusion part 6 is connected to the support part 48, and there is a gap 54 between the support part 48 and the cleaning part 34, or the cleaning part 34 is connected to the support part 48, and there is a gap 54 between the support part 48 and the extrusion part 6; the said gap 54 serves as the swinging space of the extrusion part 6. In this example, the extrusion part 6 is connected to the support part 48, and there is a gap 54 between the support part 48 and the cleaning part 34.

[0090] The extrusion part 6 is a plate-shaped body with a front high and rear low shape. The front edge of the plate-shaped body is a narrow end 6.1, and the narrow end 6.1 is arranged in an arc shape. The rear part of the plate-shaped body is a cuboid part with a gradually decreasing thickness from front to back; in the initial state, the front edge protrudes forward horizontally compared with the cleaning part 34. When the arc-shaped narrow end 6.1 is affected by the upward pulling force of the flat mop, under the support of the elastic part 35, the extrusion part 6 can swing upward by a certain angle relative to the brush plate, so that through the swing, the horizontal extrusion distance formed between the arc-shaped narrow end 6.1 and the extrusion port 3 changes from small to large; when the arc-shaped narrow end 6.1 is affected by the downward insertion force of the flat mop, it swings downward, but under the support of the support part 48, the swing amplitude is small.

[0091] The cleaning part 34 includes a brush plate 19 and brush teeth 50. In this example, the brush plate 19 is a rectangular body, and the brush teeth 50 are convex bodies protruding forward from the rectangular body; the brush plate 19 is provided with a connection structure, and this connection structure is used to install the extrusion and cleaning part in the water squeezing structure.

[0092] The brush teeth 50 are cylinders, and each row of brush teeth is evenly distributed in multiple rows and columns. Of course, the brush teeth 50 can also have other structures, such as cones, or elliptical cylinders, or serrated bodies, or polyhedrons. The brush teeth can also have other structures, such as being evenly distributed in a staggered manner in multiple rows and columns, or being arranged irregularly.

[0093] The connection structure includes connection parts, which are respectively arranged at the left and right ends of the brush plate 19. The said connection parts are fixedly connected to the water squeezing structure. The fixed connection can be, for example, plug-in fixation, or snap fixation, or screw fixation. In this example, it is plug-in fixation.

[0094] The connecting part includes fitting protrusions 49 provided at the left and right ends of the brush plate 19. First holes 51 for fitting with the fitting protrusions 49 are provided on both the left and right side surfaces of the extrusion port 3. The first holes 51 limit the fitting protrusions 49 in the up and down directions. The first holes 51 communicate with the lower part of the extrusion port 3 through first grooves 53 arranged in the up and down direction.

[0095] The left and right ends of the brush plate 19 protrude from the left and right ends of the extrusion part 6. The left and right ends of the brush plate 19 are fixedly connected to the corresponding side surfaces of the extrusion port 3. The end surfaces of the left and right ends of the extrusion part 6 are in clearance fit with the corresponding side surfaces of the extrusion port 3. The fixed connection can be, for example, plug-in fixation, or snap fixation, or screw fixation. In this example, it is plug-in fixation.

[0096] During installation, by utilizing the elastic deformation of the left and right side surfaces of the extrusion port 3, the fitting protrusions 49 at the left and right ends of the brush plate 19 are squeezed into the first grooves 53 from below the extrusion port 3 and move upward along the first grooves 53 until the fitting protrusions 49 are snapped into the first holes 51 to achieve circumferential limitation. The parts of the left and right ends of the brush plate 19 located below the fitting protrusions 49 are then fitted with the first grooves 53, thereby strengthening the fixation of the brush plate 19.

[0097] In order to facilitate the squeezing-in, a guiding inclined surface 52 is provided on the upper part of the fitting protrusion 49. The shape of the fitting protrusion 49 can be square, or rectangular, or flat elliptical, or triangular, etc.

[0098] After the extrusion and cleaning part is designed in this way, without a spring, the extrusion and cleaning part can be made by integrally injection molding with engineering plastics, and the production and assembly are greatly simplified, and the cost is significantly reduced.

[0099] A cover 14 is installed on the outer barrel 1. The cover 14 is provided with a water inlet and outlet 21 near the edge of the outer barrel 1. The cover 14 is also provided with a handle 24. A part of the handle 24 is located at the water inlet and outlet 21. An extrusion port 3 is provided on the other side of the cover 14 opposite to the side where the water inlet and outlet 21 is located. This water inlet and outlet 21 has three functions: 1. It is convenient to take out the handle 24 from inside the cover 14, that is, put the hand into the water inlet and outlet 21 and then hook a part of the handle 24, so that the handle 24 can be pulled up, which is convenient to take out the handle 24 from inside the cover 14; 2. It is convenient to add water to the inner barrel 2, that is, by using the rotation of the inner barrel, when the inner barrel 2 is located below the water inlet and outlet 21, water can be added to the inner barrel 2 through the water inlet and outlet 21; 3. There is no need to separately provide a drain port, and it is convenient for the dirty water in the inner and outer barrels to gather here and be poured out, that is, by using the rotation of the inner barrel, when the interval 4 is located below the water inlet and outlet 21, when pouring water, the water poured out from the interval 4 flows towards the side of the water inlet and outlet 21, and the water poured out from the inner barrel 2 also flows towards the side of the water inlet and outlet 21, which is convenient for the dirty water in the inner and outer barrels to gather here and be poured out.

[0100] The cover 14 is also provided with a first recess 22, a second recess 23, and a connecting buckle 25. The first recess 22 is provided at the rotary handle 11, so that the rotary handle 11 does not protrude too much from the cover 14, and at the same time helps to reduce the overall axial length of the rotary handle 11, the shaft sleeve 12, and the rotating shaft 13. Due to the relative rotation of the inner and outer barrels, the water inlet and outlet 21 can be switched between the two positions. When in the inner barrel 2 position, the water inlet and outlet 21 can be used to fill water into the inner barrel 2 or to pour water. The connecting buckle 25 is used for detachable connection, and the detachable connection enables the cover 14 to be detachably connected to the outer barrel 1. In this way, disassembling the cover 14 from the outer barrel 1 is conducive to cleaning the dirt inside the inner and outer barrels and repairing faults.

[0101] The extrusion opening 3 includes a roller 26 and a guide rib 27 , which is more conducive to the flat mop 20 being pulled back and forth along the extrusion opening 3 .

[0102] A second elastic block 30 is provided on the inner bottom surface of the inner barrel 2, and an elastic block mounting seat 31 is provided on the outer side of the inner barrel 2. The first elastic block 29 is mounted on the elastic block mounting seat 31. The first elastic block 29 is located in the interval 4. Due to the relative rotation of the inner and outer barrels, the position of the interval 4 changes relative to the inner barrel 2. The first elastic block 29 rotates together with the inner barrel 2, so that the first elastic block 29 can be guaranteed to always be in the interval 4. The main function of the first elastic block 29 is that a small amount of water will inevitably flow into the interval 4 during squeezing, so there is still water in the interval 4. The first elastic block 29 plays the role of raising the distance from the bottom surface of the squeezing area, so that when squeezing, the lower end of the flat mop 20 will not be immersed in the water in the bottom surface of the interval 4. At the same time, the first elastic block 29 can elastically support when it abuts against the lower end of the flat mop 20. The elastic support will push the lower end of the flat mop 20 upward, so that the flat mop 20 is pulled upward with less effort. The main function of the second elastic block 30 is to provide elastic support when it abuts against the lower end of the flat mop 20. The elastic support will push the lower end of the flat mop 20 upward, making it easier to pull the flat mop 20 upward. In addition, the setting of the elastic block can absorb impact energy, reduce collision noise, and increase the service life of components such as the flat mop 20.

[0103] A rotating matching sleeve 32 is provided at the bottom of the inner barrel 2, and a rotating matching column 33 provided at the bottom of the outer barrel 1 is rotatably matched with the rotating matching sleeve 32. The rotating matching column 33 and the rotating matching sleeve 32 can be rotatably conically matched. Such a structure is simple, low-cost, and the support is stable and reliable.

[0104] The inner barrel 2 can also be changed, such as Figure 19 and 20As shown, the inner barrel 2 is basically divided into three parts distributed circumferentially. One part can be called the main body 37, and the two parts on both sides of the main body 37 can be called the two wing parts 36. These three parts are interconnected and are basically evenly distributed circumferentially. The advantage of this is that after filling with water, the center of gravity of the inner barrel 2 is basically overlapped with the axis of rotation of the inner barrel, making the center of the entire cleaning barrel as centered as possible, maintaining rotational balance and avoiding eccentricity as much as possible. After the inner and outer barrels are sleeved, the part of the outer barrel 1 between the two wing parts 36 is the interval 4. As the inner barrel rotates, the position of the interval 4 also changes.

[0105] Of course, in order to handle eccentricity, the inner barrel 2 can also be two parts or more.

[0106] An arrow is provided on the upper surface of the rotating handle 11, and the status character pointed by the arrow indicates the current status, or which position it is in. For example Figure 10 When the arrow points to WASH, it means that the extrusion port 3 is in the inner barrel 2, that is, in the cleaning state. At this time, the extrusion structure can be used for cleaning.

[0107] The above-mentioned connection can be that the outlet is above the inlet, the outlet is on the side of the inlet, etc. As long as it is ensured that the water flowing out of the outlet falls into the inlet. Of course, other connection methods are not excluded. Any connection structure that conforms to the general concept of the present invention is applicable.

[0108] Obviously, compared with the prior art, the space utilization rate of this cleaning barrel is high. While ensuring the space of the cleaning area and the squeezing area, the overall volume can be relatively small.

[0109] Such as Figure 24 As shown, a cleaner using the above-mentioned cleaning barrel includes a cleaning barrel and a flat mop 20. The flat mop 20 can be movably sleeved with the extrusion port 3 of the cleaning barrel. Figure 21 The state shown is that a part of the flat mop 20 is exactly inserted into the extrusion port 3 and can be reciprocally pulled along the extrusion port 3.

[0110] The above is only the preferred embodiment of the present invention. The directional description is only for clearly describing the relative position relationship and does not constitute a limitation on the protection scope of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent application are included in the scope of the present invention patent application.
