Description

Technical Field

[0001] This application relates to the field of everyday consumer goods technology, and in particular to a cleaning tool. Background Technology

[0002] Mops are common cleaning tools in daily life. Flat mops are widely used due to their advantages such as large cleaning area and ease of use. Currently, the market uses mop buckets to wash and wring out flat mops. During the wringing process, the liquid on the mop is squeezed out mainly by a squeezing device on the bucket. In this process, users need to exert force to move the mop up and down to overcome the squeezing friction between the mop and the squeezing device, resulting in a poor user experience. Summary of the Invention

[0003] This application provides a cleaning tool that, by providing a water-absorbing device to generate suction, can absorb liquid from the mop, allowing users to wring out the mop more effortlessly and improving the user experience.

[0004] In a first aspect, embodiments of this application provide a cleaning tool, including: a mop and a mop bucket, the mop bucket including: a mop channel for inserting the mop and a bucket body; and a water-absorbing device located in the bucket body for generating suction to absorb liquid on the mop inserted into the mop channel.

[0005] The cleaning tool provided in this application embodiment, by setting a water-absorbing device inside the bucket to generate suction, can absorb liquid from the mop through the suction generated by the water-absorbing device, providing a more labor-saving way to dehydrate and improving the user experience.

[0006] Optionally, the water-absorbing device includes a water inlet structure and a power unit. The water inlet structure is disposed adjacent to the mop channel and connected to the power unit. The power unit is used to generate suction to absorb liquid on the mop inserted into the mop channel.

[0007] Optionally, the space within the power unit is increased to create a negative pressure within the power unit, thereby generating suction.

[0008] The cleaning tool provided in this application includes a water inlet structure and a power unit. Suction is generated by increasing the negative pressure created by increasing the space inside the power unit. This method of liquid suction is convenient, quick, and simple to manufacture.

[0009] Optionally, the power unit includes a deformable airbag connected to the water inlet structure; and the airbag can be gradually inflated, the space inside the airbag gradually increasing to create a negative pressure inside the airbag to generate suction to draw liquid from the mop inserted into the mop channel.

[0010] The cleaning tool provided in this application embodiment uses an airbag designed as a power device to generate suction. Since the airbag itself is deformable, it simplifies the need for additional components that would otherwise require changing the space of the power device. The structure is simple and easy to implement.

[0011] Optionally, the substance inside the airbag can be expelled and the airbag can be compressed, with the space inside the airbag gradually decreasing; the airbag can gradually expand from a compressed state, with the space inside the airbag gradually increasing to create a negative pressure inside the airbag to generate suction.

[0012] Optionally, the airbag creates negative pressure and generates suction to draw liquid from the water inlet structure into the airbag.

[0013] Optionally, the lower end of the airbag is provided with a first water outlet valve for discharging the substance inside the airbag, the first water outlet valve only allowing the substance inside the airbag to enter the barrel.

[0014] The cleaning tool provided in this application embodiment has a first water outlet valve at the lower end of the air bladder. This valve serves two purposes: first, it can discharge substances from the air bladder to compress it; second, it prevents external substances from entering the air bladder. This not only prevents liquid in the container from flowing back into the air bladder, but also allows the air bladder to have a relatively sealed environment during expansion, making it easier to form negative pressure and generate suction.

[0015] Optionally, a first water inlet valve is provided at the connection between the airbag and the water inlet structure, and the first water inlet valve only allows substances inside the water inlet structure to enter the airbag.

[0016] The cleaning tool provided in this application embodiment, combined with the first water outlet valve and the first water inlet valve set at the connection between the airbag and the water inlet structure, can make the airbag form a better sealed environment at the beginning of inflation, which is conducive to the rapid and better formation of negative pressure in the airbag and the generation of better suction.

[0017] Optionally, when the mop moves through the mop channel, it causes the airbag to deform, so as to expel the substance inside the airbag or to create negative pressure to generate suction.

[0018] Optionally, during the downward movement of the mop, the substance inside the airbag is discharged through the first water outlet valve and the airbag is compressed, and the space inside the airbag gradually decreases; during the upward movement of the mop, the airbag gradually expands from the compressed state, and the space inside the airbag gradually increases so that a negative pressure is formed inside the airbag to generate suction.

[0019] The cleaning tool provided in this application embodiment, whether operated with one hand or two hands (one hand operating the airbag and the other hand operating the mop), makes the operation relatively simple and convenient for the user by making the compression and expansion of the airbag move in the same direction as the movement of the mop, thereby improving the user experience.

[0020] Optionally, as the mop moves downward, the mop acts on the airbag to compress it.

[0021] The cleaning tool provided in this application embodiment deforms the airbag by moving the mop, so that the water absorption process can be achieved simply by moving the mop, without the need for additional operation of the airbag. The operation process is simple, effectively reducing the complexity of user operation and greatly improving the user experience.

[0022] Optionally, a pressure plate is provided inside the bucket to act on the airbag during the downward movement of the mop.

[0023] The cleaning tool provided in this application embodiment has a pressure plate on the airbag. As the mop moves downward, the pressure plate acts on the airbag to compress it. Compared with the method of the mop acting directly on the airbag, the contact area between the pressure plate and the airbag is larger. The pressure plate acts on the airbag, which can make the airbag more uniformly stressed, compress the airbag well, and improve the service life of the airbag.

[0024] Optionally, during the downward movement of the mop, the bottom end of the mop head abuts against the pressure plate to act on the pressure plate.

[0025] The cleaning tool provided in this application embodiment acts on the pressure plate through the mop head, without the need for additional parts, and has a relatively simple structure that is easy to implement.

[0026] Optionally, the water inlet structure passes through the pressure plate to communicate with the airbag.

[0027] Optionally, the bucket body is provided with a first limiting structure for restricting the movement of the pressure plate in a first plane, the first plane being perpendicular to the direction of movement of the mop, and the first limiting structure being slidably connected to the pressure plate in the direction of movement of the mop.

[0028] The cleaning tool provided in this application embodiment can improve the stability of the pressure plate during movement by setting a first limiting structure for restricting the movement space of the pressure plate in a first plane perpendicular to the movement direction of the mop, thereby improving the stability of the water absorption device.

[0029] Optionally, the pressure plate is provided with a first limiting port for the insertion of the first limiting structure, and the first limiting port is slidably engaged with the first limiting structure.

[0030] Optionally, the first limiting port has a U-shaped structure.

[0031] The cleaning tool provided in this application embodiment designs the first limiting port as a U-shaped structure. One end of the U-shaped structure has an opening to form an open end, which facilitates the installation of the first limiting structure on one side of the open end. This allows for a reasonable layout of the space inside the bucket, making the structure inside the bucket compact.

[0032] Optionally, the pressure plate is provided with two first limiting ports opposite each other along the first direction, and the barrel is provided with two first limiting structures corresponding one-to-one with the two first limiting ports along the first direction. The first limiting structures are inserted into the corresponding first limiting ports, and the first direction is parallel to the width direction of the mop head.

[0033] The cleaning tool provided in this application embodiment, by setting two first limiting structures for limiting the active space of the pressure plate in a first plane perpendicular to the moving direction of the mop, and setting two corresponding first limiting holes on the pressure plate, can make the pressure plate be subjected to uniform force and improve the stability of the pressure plate movement process.

[0034] Optionally, the first limiting structure is disposed between the airbag and the mop channel to limit the airbag to one side of the mop channel.

[0035] The cleaning tool provided in this application saves space occupied by the airbag in the bucket by placing the airbag on one side of the mop channel; moreover, since the space below the mop channel in the bucket is not occupied, water can be added in this space to clean the mop, which increases the way to clean the mop and improves flexibility.

[0036] Optionally, the lower end of the first limiting structure is connected to the inner bottom wall of the barrel.

[0037] Optionally, the barrel body is further provided with a support partition for supporting the airbag. The support partition is provided with an opening that matches the first water outlet valve, and the support partition and the inner bottom wall of the barrel body form a receiving space to facilitate the discharge of the substance in the airbag into the barrel body.

[0038] The cleaning tool provided in this application embodiment has a support partition below the airbag to support the airbag. The support partition and the inner bottom wall of the bucket form a receiving space through the opening on the support partition that matches the first water outlet valve, which allows the material in the airbag to be discharged into the bucket more smoothly.

[0039] Optionally, the side wall of the barrel is provided with a water outlet, which is connected to the first water outlet valve through the receiving space, so as to discharge the liquid discharged from the air bag into the barrel.

[0040] The cleaning tool provided in this application embodiment allows the liquid discharged from the airbag to flow smoothly to the outlet and be discharged from the outlet, emptying the liquid inside the bucket, by connecting the containing space with the water outlet of the bucket.

[0041] Optionally, the support partition has a hollow structure.

[0042] Optionally, the water inlet structure includes a water inlet section and a first guide pipe, wherein the airbag is connected to the water inlet section through the first guide pipe, and one end of the first guide pipe is movably inserted into the airbag.

[0043] The cleaning tool provided in this application embodiment has one end of the first guide tube of the water inlet structure movably inserted into the air bladder, which allows the air bladder to move relative to the first guide tube when it deforms, so that the air bladder always remains connected to the first guide tube, and thus always remains connected to the water inlet structure.

[0044] Optionally, the power unit includes a water suction cylinder and a movable plug that is sealed to the water suction cylinder. The water suction cylinder is disposed in the barrel and located on one side of the mop channel. The movable plug can move upward within the water suction cylinder, and a first space between the movable plug and the lower end of the water suction cylinder gradually increases to create a negative pressure in the first space to generate suction and draw liquid from the mop inserted into the mop channel.

[0045] The cleaning tool provided in this application embodiment includes a power unit comprising a water suction cylinder and a movable plug. Since the water suction cylinder is located inside the bucket and on one side of the mop channel, it only occupies a portion of the bucket's space, leaving the space below the mop channel empty. Therefore, water can be added to this space to clean the mop, increasing the method of cleaning the mop and improving flexibility. Through the sealed cooperation of the water suction cylinder and the movable plug during their movement, a negative pressure can be effectively formed in the first space between the lower end of the water suction cylinder and the movable plug, generating good suction. In addition, the water suction cylinder is easier to fix inside the bucket to ensure the stability of the water suction device.

[0046] Optionally, the movable plug can move downwards within the suction cylinder, causing the material in the first space to be discharged and the first space to gradually decrease; the movable plug can also move upwards within the suction cylinder, causing the first space to gradually increase so that a negative pressure is formed within the first space to generate suction.

[0047] Optionally, the first space between the movable plug and the lower end of the absorbent cylinder gradually increases to form a negative pressure and generate suction, so as to draw the liquid on the mop from the water inlet structure into the absorbent cylinder.

[0048] Optionally, the lower end of the suction cylinder is provided with a second water outlet valve for discharging the substance in the first space. The second water outlet valve only allows the substance in the suction cylinder to enter the barrel.

[0049] The cleaning tool provided in this application embodiment has a second water outlet valve on the suction tube. This valve serves two purposes: first, it can discharge the material in the first space inside the suction tube to reduce the volume of the first space; second, it prevents external material from entering the first space at the location of the second water outlet valve. This not only prevents the liquid inside the tube from flowing back into the suction tube, but also allows the first space to have a relatively sealed environment as much as possible during the upward movement of the movable plug, making it easy to form negative pressure and generate suction.

[0050] Optionally, a second water inlet valve is provided in the water suction cylinder at the connection point with the water inlet structure. The second water inlet valve only allows substances in the water inlet structure to enter the water suction cylinder.

[0051] The cleaning tool provided in this application embodiment, combined with the second water outlet valve, the design of the second water inlet valve allows the movable plug to move upward in the water suction cylinder, so that the first space gradually increases and a better sealing environment is formed in the first space, which is conducive to the rapid and better formation of negative pressure in the first space and the generation of better suction.

[0052] Optionally, when the mop moves through the mop channel, it causes the movable plug to move up and down inside the water suction cylinder to discharge substances from the first space or to gradually increase the first space to create negative pressure and generate suction.

[0053] Optionally, during the downward movement of the mop, the movable plug moves downward within the suction cylinder, and the material in the first space is discharged through the second water outlet valve, causing the first space to gradually decrease; during the upward movement of the mop, the movable plug moves upward within the suction cylinder, and the first space gradually increases to create a negative pressure within the first space, thereby generating suction.

[0054] The cleaning tool provided in this application embodiment, whether operated with one hand or two hands (one hand operating the movable plug and the other hand operating the mop), makes the operation of the movable plug in the water suction tube relatively simple and convenient for the user, and improves the user experience, by making the movement of the movable plug in the water suction tube in the same direction as the movement of the mop.

[0055] Optionally, during the downward movement of the mop, the mop acts on the movable plug to drive the movable plug to move downward within the suction cylinder.

[0056] The cleaning tool provided in this application embodiment moves the movable plug by moving the mop. The water absorption process can be achieved simply by moving the mop, without the need for additional operation of the movable plug. The operation is simple, effectively reducing the complexity of user operation and greatly improving the user experience.

[0057] Optionally, a drive unit is connected to the movable plug, and during the downward movement of the mop, the mop drives the movable plug to move downward inside the water suction cylinder through the drive unit.

[0058] Optionally, the drive unit is disposed on one side of the water suction cylinder and located below the mop channel.

[0059] The cleaning tool provided in this application embodiment has a relatively simple structure and is easy to implement. By placing the drive unit on one side of the water suction cylinder and below the mop channel, the bottom end of the mop head can abut against the drive unit during the movement of the mop. No additional parts are required.

[0060] Optionally, the bucket body is provided with a second limiting structure for restricting the movement of the drive unit in a first plane, the first plane being perpendicular to the moving direction of the mop, and the second limiting structure being slidably connected to the drive unit in the moving direction of the mop.

[0061] The cleaning tool provided in this application embodiment improves the stability of the drive unit during movement by setting a second limiting structure for restricting the activity space of the drive unit in a first plane perpendicular to the moving direction of the mop, thereby improving the stability of the water absorption device.

[0062] Optionally, the driving part is provided with a second limiting port for the second limiting structure to be inserted, and the second limiting port is slidably engaged with the second limiting structure.

[0063] Optionally, the drive unit is provided with two second limiting ports opposite each other along the first direction, and the barrel body is provided with two second limiting structures corresponding one-to-one with the two second limiting ports, and the second limiting structures are inserted into the corresponding second limiting ports.

[0064] The cleaning tool provided in this application embodiment, by setting two second limiting structures for limiting the activity space of the drive part in a first plane perpendicular to the moving direction of the mop, and setting two corresponding second limiting ports on the drive part, can make the drive part bear force evenly and improve the stability of the drive part during movement.

[0065] Optionally, the barrel body is provided with an elastic reset member, which is connected to the driving part and sleeved outside the second limiting structure, so as to drive the movable plug to move upward through the driving part.

[0066] The cleaning tool provided in this application embodiment allows the movable plug to automatically move upward to reset via an elastic reset member, avoiding the need for additional operations to move the movable plug upward, simplifying user operation and improving user experience; moreover, the second limiting structure can support the elastic reset member, preventing the elastic reset member from twisting after deformation.

[0067] Optionally, the barrel body is provided with an elastic reset member, which is connected to the movable plug to drive the movable plug to move upward.

[0068] The cleaning tool provided in this application embodiment allows the movable plug to automatically move upward to reset via an elastic reset member, avoiding the need for additional operations to move the movable plug upward, simplifying user operation and improving user experience.

[0069] Optionally, the movable plug and the drive unit are connected by a connecting arm.

[0070] Optionally, the mop bucket further includes a bucket lid connected to the bucket body; and the connecting arm is movably inserted through the bucket lid, with the upper end of the connecting arm exposed above the bucket lid when the movable plug moves downward to the limit position of the suction tube.

[0071] The cleaning tool provided in this application embodiment allows the connecting arm to move within the suction tube while the movable plug moves inside the suction tube without affecting the sealing fit between the movable plug and the suction tube. The design is simple and easy to implement. Furthermore, the portion of the connecting arm exposed outside the lid allows the user to pull up the connecting arm to move the movable plug upward within the suction tube, facilitating user operation.

[0072] Optionally, the connecting arm has an inverted U-shaped structure.

[0073] Optionally, the water inlet structure includes a water inlet section and a first guide pipe, and the water suction cylinder is connected to the water inlet section through the first guide pipe.

[0074] Optionally, the water inlet structure includes a water inlet section and a first guide pipe, and the power unit is connected to the water inlet section through the first guide pipe.

[0075] Optionally, the first guide tube is a flexible tube.

[0077] Optionally, the water inlet structure is provided with a first connector, and the inner top wall of the bucket lid is provided with a second connector, and the first connector and the second connector are connected.

[0078] Optionally, the water inlet structure has a first opening at one end near the mop channel, and the mop bucket is also provided with a second guide pipe. One end of the second guide pipe is used to connect to an external water source, and the other end is connected to the water inlet structure, so as to introduce the external water source into the water inlet structure and discharge it from the first opening of the water inlet structure to clean the mop inserted into the mop channel.

[0079] The cleaning tool provided in this application embodiment can introduce external water into the water inlet structure and discharge it from the first opening of the water inlet structure through the external second guide tube. It can clean the mop while the mop is inserted into the mop channel, and can be completed in one operation. It does not require the multiple steps of first adding water and then placing the mop and moving the mop up and down to clean it, as is the case with the prior art. This effectively reduces the operation process and improves the user experience.

[0080] Optionally, the mop bucket further includes a bucket lid connected to the bucket body; and the bucket lid is provided with a water inlet penetrating through the bucket lid, and the inner top wall of the bucket lid is provided with a second guide pipe, the second guide pipe being connected to the water inlet and the water inlet structure respectively.

[0081] The cleaning tool provided in this application embodiment allows external water to enter from the top of the lid by setting an inlet on the lid for connecting to an external water source, which conforms to the user's usage habits and improves the user experience.

[0082] Optionally, the bucket lid is provided with a connecting channel for connecting an external pipe, the connecting channel extending out of the bucket lid and communicating with the water inlet.

[0083] Optionally, when the mop extends into the bucket through the mop channel with the maximum travel distance, at least a portion of the first opening is located above the mop head.

[0084] The cleaning tool provided in this application embodiment has a first opening with at least a portion of the area above the mop head, so that at least a portion of the first opening does not contact the mop head, allowing water to flow smoothly out of the at least a portion of the area and down to the mop head, which facilitates cleaning the mop.

[0085] Optionally, the first opening is located above the mop head of the mop.

[0161] To address the issue of excessive effort required by users during the wringing process of existing mops, this application provides a cleaning tool that incorporates a suction device to generate suction. This allows users to move the mop without exerting too much force, using the suction generated by the device to remove liquid from the mop. This enables users to wring the mop more efficiently, improving the user experience.

[0162] Figure 1 This is a schematic diagram of the structure of a cleaning tool with an airbag 42 provided in an embodiment of this application. Figure 2 yes Figure 1 Exploded view.

[0163] refer to Figure 1 and Figure 2The cleaning tool in this application embodiment includes a mop 1 and a mop bucket. The mop bucket includes a mop channel 21, a bucket body 3, and a water absorption device 4. The mop 1 can be inserted into the mop channel 21 and moved within the bucket body 3. The water absorption device 4 is located within the bucket body 3 and is used to generate suction to absorb liquid on the mop 1 during its movement.

[0164] During the water absorption process, the mop 1 can move upward, downward, or up and down. This application embodiment does not impose any limitations. The following is a detailed description in conjunction with the specific structure.

[0165] It should be noted that the upward or downward or up-and-down movement of the mop 1 mentioned in the embodiments of this application refers to the movement of the cleaning tool in its normal state when the mop 1 is inserted into the mop channel 21. When the mop 1 moves upward, the mop 1 slowly moves out of the bucket 3. When the mop 1 moves downward, the mop 1 slowly extends into the bucket 3.

[0166] The cleaning tool provided in this application embodiment, by setting a water-absorbing device 4 for generating suction inside the bucket 3, allows the user to move the mop 1 without too much force, so that the liquid on the mop 1 can be absorbed by the suction generated by the water-absorbing device 4, providing a more labor-saving way of dehydration and improving the user experience.

[0167] refer to Figure 2 The mop 1 can be a flat mop, including a mop handle 11 and a mop head 12. The mop handle 11 and the mop head 12 are rotatably connected. When the mop head 12 is rotated to a state that is substantially parallel to the mop handle 11, the mop head 12 and the mop handle 11 can be inserted into the mop channel 21 and can move up and down within the bucket body 3. The mop head 12 includes a mop board 121 and a wiping material 122. The wiping material 122 is detachably connected to one side of the mop board 121. When in use, the wiping material 122 can be attached to the mop board 121, and when not in use, the wiping material 122 can be removed from the mop board 121.

[0168] refer to Figure 2 In some embodiments, the mop bucket includes a lid 2 connected to the bucket body 3, and a mop channel 21 is disposed on the lid 2. Exemplarily, the lid 2 and the bucket body 3 can be detachably connected or integrally formed; this application embodiment does not impose any limitation. For example, refer to... Figure 2 and Figure 4 As shown, the bucket lid 2 has an opening that extends through the bucket lid 2 to form a mop channel 21.

[0169] refer to Figure 2The water-absorbing device 4 includes a water inlet structure 41 and a power unit (e.g., an airbag 42). The water inlet structure 41 is located adjacent to the mop channel 21 and connected to the power unit. The power unit is used to generate suction to draw liquid from the water inlet structure 41 into the power unit as the mop 1 moves.

[0170] In the embodiments of this application, there are various types of methods and structures for generating suction through a power device.

[0171] In some embodiments, the space within the power unit is increased to create a negative pressure within the power unit, thereby generating suction. In one example, the power unit includes a deformable airbag 42, and suction is generated by increasing the space within the airbag 42 through deformation of the airbag 42. Figures 1 to 24 as well as Figures 25 to 35 As shown. In another example, the power unit includes a suction cylinder 44 and a movable plug 451, which generate suction through a first space 441 that widens between the suction cylinder 44 and the movable plug 451, as illustrated. Figures 36 to 48 As shown.

[0172] In other embodiments, the power unit includes a pump 47, which generates suction, such as... Figures 49 to 55 as well as Figures 56 to 59 As shown.

[0173] The cleaning tools of this application will now be described in detail using examples of a power unit including an airbag 42, a power unit including a water suction cylinder 44 and a movable plug 451, and a power unit including a pump 47. The cleaning tool with a power unit including an airbag 42 corresponds to... Figures 1 to 24 as well as Figures 25 to 35 The structure shown includes a power unit corresponding to a cleaning tool, comprising a suction cylinder 44 and a movable plug 451. Figures 36 to 48 The structure shown includes a power unit corresponding to a pump 47 for cleaning tools. Figures 49 to 55 as well as Figures 56 to 59 The structure shown.

[0174] refer to Figure 2 The water-absorbing device 4 includes a water inlet structure 41 and a deformable airbag 42 (the airbag 42 is an example of a power device). The water inlet structure 41 is located adjacent to the mop channel 21 and is connected to the airbag 42. The airbag 42 is used to generate suction to draw liquid on the mop 1 from the water inlet structure 41 into the airbag 42 as the mop 1 moves.

[0175] Figure 3 This is an exploded view of the water-absorbing device 4 with an airbag 42 provided in an embodiment of this application. (Reference) Figure 3 The water inlet structure 41 has a first opening 4111 at one end near the mop channel 21 (e.g., Figure 3As shown in (b) of the diagram, liquid on the mop 1 can enter the water inlet structure 41 through the first opening 4111.

[0176] During the water absorption process, the mop 1 can move upwards and downwards to maximize the contact between the wiping material 122 of the mop head 12 and the first opening 4111 of the water inlet structure 41. This allows for better absorption of liquid from the mop head 12, achieving a better water absorption effect. Furthermore, during the water absorption process, there is essentially no gap or a very small gap between the wiping material 122 of the mop head 12 and the first opening 4111. Preferably, the wiping material 122 of the mop head 12 and the first opening 4111 can be in a slightly compressed state to achieve even better water absorption.

[0177] Figure 4 This is an exploded view of the mop bucket provided in an embodiment of this application. (Reference) Figures 2 to 4 In some embodiments, the water inlet structure 41 includes a water inlet portion 411 and a first guide pipe 412. The water inlet portion 411 is disposed adjacent to the mop channel 21 (e.g., Figure 4 As shown), a first opening 4111 is formed at one end of the water inlet 411 near the mop channel 21. One end 4122 of the first guide tube 412 is connected to the airbag 42. For example, one end 4122 of the first guide tube 412 is connected to the airbag 42 through the upper opening 422 of the airbag 42, and the other end 4121 of the first guide tube 412 is connected to the other end 4112 of the water inlet 411. Thus, the airbag 42 and the water inlet 411 are connected through the first guide tube 412.

[0178] In order to achieve the connection between the airbag 42 and the first guide tube 412 during the deformation of the airbag 42, in one example, one end 4122 of the first guide tube 412 is movably inserted through the airbag 42. In this way, when the airbag 42 moves relative to the first guide tube 412 during deformation, the airbag 42 can always maintain the connection with the first guide tube 412, so as to always maintain the connection with the water inlet 411.

[0179] In other examples, the first flow tube 412 may also be fixedly connected to the airbag 42. The first flow tube 412 is made of a deformable material, and the first flow tube 412 deforms when the airbag 42 deforms.

[0180] For example, the first guide tube 412 can be a flexible tube.

[0181] Because the hose is flexible and easily deformable, for example, it is easy to bend. First, it is convenient to install the water inlet structure 41 in the limited space of the barrel 3. Second, while realizing the connection between the water inlet structure 41 and the air bag 42, the air bag 42 can be deformed to a greater extent to generate better suction.

[0182] In this embodiment, the airbag 42 can generate suction by expanding. That is, the airbag 42 can gradually expand, and the space inside the airbag 42 gradually increases so that a negative pressure is formed inside the airbag 42 to generate suction, so as to draw the liquid on the mop 1 from the water inlet structure 41 into the airbag 42 during the movement of the mop 1.

[0183] Figure 5 This is a schematic diagram showing the airbag 42 in a compressed state and an inflated state according to an embodiment of this application. Figure 5 (a) shows a schematic diagram of the airbag 42 in a compressed state. Figure 5 Figure (b) shows a schematic diagram of the airbag 42 in an inflated state.

[0184] In some embodiments, reference Figure 5 To inflate the airbag 42, it can be first compressed and then inflated. Specifically, refer to... Figure 5 In (a), the material inside airbag 42 can be expelled and airbag 42 is compressed, and the space inside airbag 42 gradually decreases; see reference. Figure 5 In (b), the airbag 42 can gradually expand from a compressed state, and the space inside the airbag 42 gradually increases so that a negative pressure is formed inside the airbag 42 to generate suction.

[0185] It should be understood that the substance within the airbag 42 may include air or liquid (water) absorbed from the mop 1; in short, the substance within the airbag 42 may include any substance that can be contained therein. If there is no liquid within the airbag 42 (e.g., during the initial absorption of water), the substance expelled from the airbag 42 upon compression of the airbag 42 will primarily consist of air; if there is liquid within the airbag 42 (e.g., liquid absorbed during the absorption process), the substance expelled from the airbag 42 upon compression of the airbag 42 will primarily consist of liquid and air.

[0186] To achieve the compression of the airbag 42, in some embodiments, reference is made to... Figure 3 The lower end of the airbag 42 is provided with a first water outlet valve 431 for discharging the material inside the airbag 42. The first water outlet valve 431 only allows the material inside the airbag 42 to enter the barrel 3. For example, the lower end of the airbag 42 has a lower opening 421, and the first water outlet valve 431 is provided on the lower opening 421.

[0187] In other words, the first outlet valve 431 is a one-way valve, which only allows the substances inside the air bladder 42 to be discharged into the tank 3, and does not allow external substances to enter the air bladder 42 at this point.

[0188] During the compression of the airbag 42, the first water outlet valve 431 opens, and the substances (air and / or liquid) inside the airbag 42 are discharged from the first water outlet valve 431, reducing the space inside the airbag 42. When the compression of the airbag 42 stops, the airbag 42 begins to expand, the first water outlet valve 431 closes, the space inside the airbag 42 increases, the pressure decreases, while the external atmospheric pressure remains unchanged, creating a negative pressure inside the airbag 42. Under the action of the pressure difference, a suction force is generated inside the airbag 42, drawing the liquid on the mop head 12 into the airbag 42.

[0189] The cleaning tool provided in this application embodiment has a first water outlet valve 431 at the lower end of the airbag 42. This valve serves two purposes: first, it can discharge substances from the airbag 42 to compress it; second, it prevents external substances from entering the airbag 42 at the location of the first water outlet valve 431. This not only prevents the liquid in the barrel 3 from flowing back into the airbag 42, but also ensures that the airbag 42 has a relatively sealed environment during its expansion, making it easy to form negative pressure and generate suction.

[0190] In some embodiments (not shown in the figures), a first water inlet valve is provided at the connection between the airbag 42 and the water inlet structure 41. The first water inlet valve only allows substances inside the water inlet structure 41 to enter the airbag 42. For example, see reference... Figure 3 The first water inlet valve can be set at the upper opening 422 of the airbag 42.

[0191] In other words, the first inlet valve is a one-way valve, which only allows substances inside the inlet structure 41 to enter the airbag 42, and does not allow substances inside the airbag 42 to enter the inlet structure.

[0192] During the compression of the airbag 42, the first outlet valve 431 opens and the first inlet valve closes, allowing the contents (air and / or liquid) inside the airbag 42 to be discharged from the first outlet valve 431, reducing the space inside the airbag 42. When the compression of the airbag 42 stops, the airbag 42 begins to expand, the first outlet valve 431 closes, and the first inlet valve remains closed, creating a near-sealed environment inside the airbag 42. The space inside the airbag 42 increases, the pressure decreases, while the external atmospheric pressure remains unchanged, creating a negative pressure inside the airbag 42. Under the pressure difference, a suction force is generated inside the airbag 42, drawing in the liquid from the mop head 12. The first inlet valve opens, and the liquid enters the airbag 42 from the water inlet structure 41.

[0193] The cleaning tool provided in this application embodiment, combined with the first water outlet valve 431 and the first water inlet valve set at the connection between the airbag 42 and the water inlet structure 41, can make the airbag 42 form a better sealed environment at the beginning of inflation, which is conducive to the rapid and better formation of negative pressure in the airbag 42 and the generation of better suction.

[0194] In this embodiment, the compression and expansion of the airbag 42 can be in the same direction as the movement of the mop 1 to improve the user experience.

[0195] In some embodiments, reference Figure 5 As the mop 1 moves downwards, the material inside the air bladder 42 is expelled through the first water outlet valve 431, and the air bladder 42 is compressed, gradually reducing the space inside it. As the mop 1 moves upwards, the air bladder 42 gradually expands from its compressed state, increasing the space inside it to create negative pressure and generate suction. In other words, when the mop 1 moves downwards, the air bladder 42 is compressed; when the mop 1 moves upwards, the air bladder 42 begins to expand, and the expansion process allows the mop 1 to absorb water.

[0196] The cleaning tool provided in this application embodiment, whether operated by one hand or two hands (one hand operates the airbag 42 and the other hand operates the mop 1), makes the operation relatively simple and convenient for the user by making the compression and expansion of the airbag 42 move in the same direction as the movement of the mop 1, thereby improving the user experience.

[0197] To better simplify operation and improve user experience, in some embodiments, reference is made to... Figure 5 As the mop 1 moves downward, it acts on the airbag 42 to compress it. Naturally, as the mop 1 moves upward, the airbag 42 is no longer acted on by the mop 1, and it gradually expands from the compressed state. Ideally, it can return to its initial uncompressed state.

[0198] It should be noted that the mop 1 acts on the airbag 42, which can mean that the mop 1 acts directly on the airbag 42, such as... Figure 5 As shown, the mop 1 can also indirectly act on the airbag 42 through other components, such as... Figure 27 The pressure plate 46 shown below will be described in detail.

[0199] It should be understood that the relationship between the compression and expansion of the airbag 42 and the direction of movement of the mop 1 described above is merely illustrative and should not be construed as limiting the embodiments of this application. Exemplarily, the compression and expansion of the airbag 42 and the direction of movement of the mop 1 may also be in different directions. For example, during the process of the airbag 42 being compressed and then expanding, the mop 1 moves upward, downward, or up and down, and the mop head 12 of the mop 1 fully contacts the first opening 4111 of the water inlet structure 41 so as to draw liquid from the mop head 12 through the airbag 42.

[0200] It should also be understood that the above description of compressing and inflating the airbag 42 using the mop 1 is merely illustrative and should not be construed as limiting the embodiments of this application. Exemplarily (not shown in the figures), a connecting rod can be provided above the airbag 42, passing through and protruding from the bucket lid 2. When the user presses the connecting rod, the rod acts on the airbag 42, compressing it. When the user lifts the connecting rod, the airbag 42 inflates.

[0201] Regarding the relationship between the water absorption device 4 and the mop bucket, the water absorption device 4 is connected to the mop bucket. For example, the water absorption device 4 can be connected to the bucket body 3 or the bucket lid 2. This application embodiment does not make any limitation.

[0202] Figure 6 This is a schematic diagram of the assembly of the water-absorbing device 4 with airbag 42 and the bucket lid 2 provided in the embodiments of this application. Figure 7 yes Figure 6 Exploded view. Figure 8 yes Figure 6 A magnified view of a portion of point A in the middle.

[0203] refer to Figures 6 to 8 The water inlet structure 41 of the water suction device 4 is connected to the bucket lid 2. For example, the water inlet portion 411 of the water inlet structure 41 is connected to the bucket lid 2.

[0204] In some embodiments, reference Figure 7 and Figure 8 The water inlet structure 41 is provided with a first connector 4113. For example, the water inlet part 411 of the water inlet structure 41 is provided with a first connector 4113, and the inner top wall of the bucket lid 2 is provided with a second connector 22. The first connector 4113 and the second connector 22 are connected to fix the water inlet structure 41 to the bucket lid 2, so as to realize the connection between the water suction device 4 and the bucket lid 2.

[0205] The first connector 4113 and the second connector 22 can be connected in various ways, without any limitation. For example, the first connector 4113 and the second connector 22 can be connected by threads, be an integral design, or be connected by snap-fit.

[0206] In this embodiment of the application, the mop 1 needs to be washed before it is used to absorb water. For similar... Figure 5 The airbag 42 shown occupies most of the space inside the tub 3, making the traditional method of first filling the tub 3 with water and then inserting the mop 1 into the tub 3 for cleaning not very suitable. Therefore, to facilitate cleaning the mop 1, this embodiment proposes to introduce external water into the water inlet structure 41 through an external second guide pipe 24 and discharge it from the first opening 4111 of the water inlet structure 41. The discharged water wets the mop head 12 to clean the mop 1.

[0207] That is, in some embodiments, a second guide pipe 24 is provided on the mop bucket. One end of the second guide pipe 24 is used to connect to an external water source, and the other end is connected to the water inlet structure 41, so as to introduce the external water source into the water inlet structure 41 and discharge it from the first opening 4111 of the water inlet structure 41 to clean the mop 1 inserted into the mop channel 21. Exemplarily, the other end of the second guide pipe 24 is connected to the water inlet portion 411 of the water inlet structure 41. The end of the water inlet portion 411 near the mop channel 21 has a first opening 4111, so as to introduce the external water source into the water inlet portion 411 and discharge it from the first opening 4111 of the water inlet portion 411.

[0208] During the water intake process, the mop 1 is inserted into the mop channel 21 and preferably moved downward to the limit position. The external water source enters the water intake structure 41 from the second guide pipe 24 and is discharged from the first opening 4111 of the water intake structure 41. The discharged water wets the mop head 12 to clean the mop head 12.

[0209] Therefore, the method of using the second guide pipe 24 to drain water from the water inlet structure 41 to clean the mop 1 provided in this application embodiment is very suitable for cleaning tools with an airbag 42 that occupies a large space inside the bucket 3, and can conveniently achieve the purpose of cleaning the mop.

[0210] In the embodiment described above where a second guide pipe 24 is provided on the mop bucket, the second guide pipe 24 can be provided on the bucket body 3, on the bucket lid 2, or on other components installed on the bucket body 3. This application embodiment does not impose any limitations. The structure of the second guide pipe 24 provided on the bucket lid 2 will be described in detail below.

[0211] Figure 9 This is a schematic diagram of the structure of the bucket lid 2 provided in the embodiment of this application. Figure 10 This is a structural schematic diagram of the bucket lid 2 provided in an embodiment of this application from another angle. Figure 11 This is a top view of a cleaning tool with an airbag 42 provided in an embodiment of this application. Figure 12 yes Figure 11 A three-dimensional cross-sectional view from the perspective of AA. Figure 13 yes Figure 12 A magnified view of point B in the image.

[0212] In some embodiments, reference Figures 9 to 13 The bucket lid 2 is provided with an inlet 23 for connecting to an external water source and penetrating through the bucket lid 2 (e.g., Figure 9 As shown), a second guide pipe 24 is provided on the inner top wall of the bucket lid 2 (as shown). Figure 10 The second guide pipe 24 connects the inlet 23 and the inlet structure 41 (e.g.) Figure 13 (As shown). For example, the second guide pipe 24 connects the water inlet 23 and the water inlet section 411 of the water inlet structure 41.

[0213] During the water intake process, external water enters the second guide pipe 24 from the water inlet 23, enters the water intake structure 41 (e.g., the water intake part 411 of the water intake structure 41) through the second guide pipe 24 and is discharged from the first opening 4111 of the water intake structure 41. The discharged water can wet the mop head 12 to clean the mop 1.

[0214] To facilitate connection to an external water source, in one example, refer to... Figure 9 and Figure 13 The bucket lid 2 is provided with a connecting channel 25 for connecting an external hose. The connecting channel 25 extends out of the bucket lid 2 and is connected to the water inlet 23. In this way, external water can enter the water inlet 23 through the connecting channel 25 and finally be discharged from the first opening 4111 of the water inlet structure 41 to wet the mop head 12 and clean the mop head 12.

[0215] Figure 14 yes Figure 11 A two-dimensional sectional view from the perspective of a BB (Black-White) plane. Figure 15 yes Figure 14 A magnified view of a section at point C.

[0216] In the above-described structure where water enters from the first opening 4111 of the water inlet structure 41 via the second guide pipe 24 to clean the mop 1, in order to ensure smooth water intake, in some embodiments, refer to Figures 13 to 15 When the mop 1 extends into the bucket 3 through the mop channel 21 with the maximum travel distance, at least a portion of the first opening 4111 of the water inlet structure 41 is located above the mop head 12 of the mop 1. Here, "at least a portion of the first opening 4111" refers to all or part of the first opening 4111.

[0217] The cleaning tool provided in this application embodiment has at least a portion of the first opening 4111 located above the mop head 12, so that at least a portion of the first opening 4111 does not contact the mop head 12, allowing water to flow smoothly out of the at least a portion of the opening and then flow down to the mop head 12, which facilitates cleaning the mop 1.

[0218] For example, the first opening 4111 is located above the mop head 12 of the mop 1. That is, the entire area of ​​the first opening 4111 is located above the mop head 12. This allows water to flow out smoothly from the first opening 4111 for easier cleaning of the mop 1.

[0219] In this embodiment, the relationship between the first opening 4111 of the water inlet structure 41 and the size design of the mop head 12 is as follows: (Refer to...) Figure 15The difference between the dimension of the first opening 4111 in the first direction and the width of the mop head 12 of the mop 1 is less than a threshold value, and the first direction is parallel to the width direction of the mop head 12. This threshold value is greater than or equal to 0, and the smaller the threshold, the better.

[0220] For example, the first opening 4111 has the same dimension in the first direction as the width of the mop head 12. This sameness can mean substantially the same, i.e., the two dimensions are the same within a certain margin of error.

[0221] It should be understood that the difference between the size of the first opening 4111 in the first direction and the width of the mop head 12 of the mop 1 is less than a threshold. This can mean that the size of the first opening 4111 in the first direction is greater than the width of the mop head 12 within the threshold range, or that the size of the first opening 4111 in the first direction is less than the width of the mop head 12 within the threshold range.

[0222] It should be noted that the design of the first opening 4111 of the water inlet structure 41 described herein and the mop head 12 (e.g., positional and dimensional relationships) applies to any of the embodiments described below, and will not be repeated hereafter.

Figure 21 of Figure 20 A magnified view of a section at point E in the middle. Figure 22 This is a schematic diagram of the structure of the support partition 5 provided in the embodiment of this application. Figure 23 of Figure 17 A magnified view of a section at point D.

[0224] refer to Figures 16 to 23 The tank body 3 is also equipped with a support partition 5 for supporting the airbag 42. The support partition 5 is provided with an opening 51 that matches the first water outlet valve 431 (e.g., Figure 21 As shown), and the supporting partition 5 and the inner bottom wall 33 of the barrel 3 form a receiving space 52 (as shown). Figure 23 (as shown), so that the material in the airbag 42 can be discharged into the barrel 3.

[0225] Specifically, refer to Figures 16 to 21A support partition 5 is disposed inside the barrel 3 and located below the airbag 42 to support the airbag 42. A first water outlet valve 431 on the airbag 42 is inserted into the opening 51 on the support partition 5, allowing the contents of the airbag 42 to be discharged through the first water outlet valve 431 and the opening 51. (Reference) Figure 22 and Figure 23 The bottom of the supporting partition 5 has a recessed area 5a with an inner wall 53. A receiving space 52 is formed between the inner wall 53 of the recessed area 5a and the inner bottom wall 33 of the barrel 3. The receiving space 52 allows the material discharged from the airbag 42 to be smoothly discharged into the barrel 3. It should be understood that, in order to smoothly discharge the material from the airbag 42 into the barrel 3, there is a gap between the first water outlet valve 431 and the inner bottom wall 33 of the barrel 3, and this gap can serve as part of the receiving space 52.

[0226] For example, the support partition 5 is movably disposed within the barrel body 3 to facilitate the removal and installation of the support partition 5.

[0227] For example, refer to Figure 22 The supporting partition 5 has a hollow structure. In this example, the hollow area of ​​the supporting partition 5 can be used as the opening 51 on the supporting partition 5.

[0228] In order to drain the liquid from tank 3, refer to Figure 23 The side wall of the barrel 3 is provided with a water outlet 32, which is connected to the first water outlet valve 431 through the receiving space 52, so as to discharge the liquid that will be discharged from the air bag 42 into the barrel 3.

[0229] During the drainage process, the liquid in the airbag 42 is discharged from the first outlet valve 431 to the containment space 52 in the barrel 3. Since the containment space 52 is connected to the outlet 32, the liquid can flow smoothly to the outlet 32 ​​and be discharged from the outlet 32.

[0230] Figure 24 This is an exploded view of the barrel 3 and water plug 31 provided in an embodiment of this application. In some embodiments, refer to Figure 24 A water plug 31 is provided on the water outlet 32 ​​of the tank body 3. When drainage is not required, the water plug 31 is installed on the water outlet 32, and when drainage is required, the water plug 31 is removed from the water outlet 32.

[0231] It should be noted that the structure of setting a water plug 31 on the water outlet 32 ​​of the barrel 3 is applicable to any of the embodiments described below, and will not be repeated hereafter.

[0232] The above, combined with Figures 1 to 24 The present application provides a detailed description of the cleaning tool with airbag 42 provided in the embodiments.

[0233] The following, combined with Figures 25 to 35This application will now describe another cleaning tool with an airbag 42 provided in an embodiment of the present application. Figures 1 to 24 The difference in the structure shown is that, Figures 25 to 35 The water-absorbing device 4 of the cleaning tool shown includes a pressure plate 46, which acts on the airbag 42 to compress the airbag 42.

[0234] Figure 25 This is an exploded view of a cleaning tool with a pressure plate 46 provided in an embodiment of this application. Figure 26 This is an exploded view of the water absorption device 4 with pressure plate 46 provided in the embodiments of this application. Figure 27 This is a schematic diagram showing the state of the airbag 42 of the cleaning tool with pressure plate 46 provided in this application embodiment when it is in a compressed state and an inflated state.

[0235] refer to Figure 25 The cleaning tools include a mop 1 and a mop bucket. The mop bucket includes a mop channel 21, a bucket body 3, and a water-absorbing device 4, which is located inside the bucket body 3. Exemplarily, the mop bucket also includes a bucket lid 2 connected to the bucket body 3, and the mop channel 21 is disposed on the bucket lid 2.

[0236] refer to Figure 25 and Figure 26 The water-absorbing device 4 includes a water inlet structure 41, a pressure plate 46, and an airbag 42. The water inlet structure 41 is disposed adjacent to the mop channel 21 and communicates with the airbag 42. A first opening 4111 is formed at one end of the water inlet structure 41 adjacent to the mop channel. Exemplarily, the water inlet structure 41 includes a water inlet portion 411 and a first guide pipe 412. The airbag 42 communicates with the water inlet portion 411 through the first guide pipe 412. The first opening 4111 is formed at one end of the water inlet portion 411 near the mop channel 21. Exemplarily, a first water outlet valve 431 is disposed at the lower end of the airbag 42. Exemplarily, a first water inlet valve is disposed at the connection point between the airbag 42 and the first guide pipe 412. For a detailed description of the water inlet structure 41 and the airbag 42, please refer to the above text. Figures 1 to 24 The relevant descriptions will not be repeated here.

[0237] refer to Figure 26 and Figure 27 The pressure plate 46 is disposed above the airbag 42 and is used to act on the airbag 42 during the downward movement of the mop 1. Exemplarily, the pressure plate 46 has a plate-like structure.

[0238] Specifically, refer to Figure 27As the mop 1 moves downward, it acts on the pressure plate 46, which in turn acts on the airbag 42, compressing it and reducing the space inside. Naturally, as the mop 1 moves upward, the airbag 42 and the pressure plate 46 are no longer acted upon by the mop 1, and the airbag 42 gradually expands from its compressed state (ideally, the airbag 42 can return to its initial uncompressed state). The space inside the airbag 42 gradually increases, creating a negative pressure inside the airbag 42 to generate suction.

[0239] The cleaning tool provided in this application embodiment has a pressure plate 46 on the airbag 42. During the downward movement of the mop 1, the pressure plate 46 acts on the airbag 42 to compress the airbag 42. Compared with the method of the mop 1 directly acting on the airbag 42, the contact area between the pressure plate 46 and the airbag 42 is larger. The pressure plate 46 acts on the airbag 42, which can make the airbag 42 more evenly stressed, compress the airbag 42 well, and improve the service life of the airbag 42.

[0240] In some embodiments, reference Figure 26 The water inlet structure 41 passes through the pressure plate 46 to communicate with the airbag 42. Exemplarily, the first guide pipe 412 of the water inlet structure 41 passes through the pressure plate 46 to communicate with the airbag 42. Specifically, the pressure plate 46 is provided with a perforation 462, and the first guide pipe 412 passes through the perforation 462 and extends into the upper opening 422 of the airbag 42 to communicate with it. This achieves a stable connection between the water inlet structure 41, the pressure plate 46, and the airbag 42.

[0241] In other embodiments (not shown in the figure), the pressure plate 46 may also be disposed on one side of the first guide tube 412, and it is not necessary for the first guide tube 412 to pass through the pressure plate 46.

[0242] Various possible designs are possible in which the mop 1 acts on the pressure plate 46 to act on the airbag 42.

[0243] In some embodiments, such as Figure 27 As shown, during the downward movement of the mop 1, the bottom end of the mop head 12 abuts against the pressure plate 46 to act on the pressure plate 46. In this embodiment, the mop head 12 acts directly on the pressure plate 46 without the need for additional components, resulting in a relatively simple and easy-to-implement structure.

[0244] In some other embodiments (not shown in the figures), a connecting rod may be provided on the mop handle 11 of the mop 1. The connecting rod is movably mounted on the bucket lid 2. During the downward movement of the mop 1, the connecting rod abuts against the pressure plate 46 to act on the pressure plate 46.

[0245] Figure 28 This is a top view of a cleaning tool with a pressure plate 46 and a first limiting structure 71 provided in an embodiment of this application. Figure 29 is Figure 28 The sectional view from the E - E perspective in Figure 30 is Figure 28 The sectional view from the F - F perspective in Figure 31 is Figure 30 The partial enlarged view at position F in

[0246] In the water absorption device 4 with the pressing plate 46 above, during the process of the mop 1 moving to drive the pressing plate 46 to move, in order to improve the stability of the pressing plate 46 during the moving process, in some embodiments, referring to Figures 28 to 31 , a first limiting structure 71 for restricting the movement of the pressing plate 46 in a first plane is arranged in the barrel body 3. The first plane is perpendicular to the moving direction of the mop 1, and the first limiting structure 71 is slidably connected to the pressing plate 46 in the moving direction of the mop 1. During the process of the mop 1 moving to drive the pressing plate 46 to move, the pressing plate 46 slides relative to the first limiting structure 71.

[0247] For the cleaning tool provided by the embodiment of the present application, by setting the first limiting structure 71 for restricting the movement space of the pressing plate 46 in a first plane perpendicular to the moving direction of the mop 1, the stability of the pressing plate 46 during the moving process can be improved, so as to improve the stability of the water absorption device 4.

[0248] Exemplarily, referring to Figures 28 to 31 , the first limiting structure 71 is in a plate - like structure. It should be understood that the first limiting structure 71 can also be other structures such as columnar, etc., and the embodiments of the present application do not make any limitations.

[0249] Exemplarily, referring to Figure 26 , a first limiting port 461 for inserting the first limiting structure 71 is arranged on the pressing plate 46. Referring to Figures 28 to 31 , the first limiting port 461 is in sliding fit with the first limiting structure 71.

[0250] Exemplarily, referring to Figure 26 , the first limiting port 461 is in a U - shaped structure.

[0251] For the cleaning tool provided by the embodiment of the present application, by designing the first limiting port 461 as a U - shaped structure, one end of the U - shaped structure has an opening, forming an open end, which is convenient for installing the first limiting structure 71 on one side of the open end, and can reasonably layout the space in the barrel body 3, making the structure in the barrel body 3 compact.

[0252] It should be understood that the first limiting port 461 can also be in other structures such as a "square" or "circle" shape, etc., and the embodiments of the present application do not make any limitations.

[0253] Exemplarily, referring to Figure 29 , the first limiting structure 71 is arranged on the inner side wall of the barrel body 3.

[0254] The embodiments of this application do not limit the number of the first limiting structure 71 and the first limiting port 461. For example, the number of the first limiting structure 71 and the first limiting port 461 can be 1, 2, etc.

[0255] In some embodiments, reference Figure 26 The pressure plate 46 has two first limiting ports 461 arranged opposite each other along the first direction, for reference. Figure 29 Inside the bucket body 3, two first limiting structures 71 are provided in opposite directions along the first direction, corresponding one-to-one with the two first limiting ports 461. The first limiting structures 71 are inserted into the corresponding first limiting ports 461. The first direction is parallel to the width direction of the mop head 12 of the mop 1.

[0256] The cleaning tool provided in this application embodiment, by setting two first limiting structures 71 for limiting the active space of the pressure plate 46 in a first plane perpendicular to the moving direction of the mop 1, and setting two corresponding first limiting holes 461 on the pressure plate 46, can make the pressure plate 46 be subjected to uniform force and improve the stability of the pressure plate 46 during movement.

[0257] It should be noted that when two first limiting structures 71 are provided inside the barrel body 3, preferably, the two first limiting ports 461 on the pressure plate 46 can be designed as U-shaped structures.

[0258] It should also be noted that when multiple (e.g., two) first limiting structures 71 are provided inside the barrel body 3, the multiple first limiting structures 71 can be designed independently of each other or can be designed as a single piece. This application embodiment does not impose any limitations.

[0259] In the cleaning tool with pressure plate 46 described above, the size of airbag 42 is not limited in the first plane, wherein the first plane is perpendicular to the direction of movement of mop 1.

[0260] In some embodiments, the airbag 42 and the mop channel 21 overlap in a first plane. That is, the airbag 42 occupies the space within the bucket 3 located below the mop channel 21, as described above. Figure 2 The airbag 42 shown.

[0261] In this embodiment, as described above, external water can be introduced into the water inlet structure 41 through the second guide pipe 24, the water inlet 23 provided on the bucket lid 2, and the connecting channel 25, and discharged from the first opening 4111 of the water inlet structure 41 to wet the mop head 12 and clean the mop 1. For a detailed description, please refer to the above description of... Figures 9 to 15 The relevant descriptions will not be repeated here.

[0262] In other embodiments, reference is made to Figure 30The airbag 42 is located on one side of the mop channel 21. That is to say, the airbag 42 and the mop channel 21 have no overlapping area in the first plane. The airbag 42 only occupies a part of the space of the bucket 3 in the first plane, leaving the space in the bucket 3 below the mop channel 21 empty.

[0263] In this embodiment, when cleaning the mop 1, in one example, external water can be introduced into the water inlet structure 41 via the second guide pipe 24, the water inlet 23 provided on the bucket lid 2, and the connecting channel 25, as described above, and discharged from the first opening 4111 of the water inlet structure 41 to wet the mop head 12 and clean the mop 1. In another example, since the airbag 42 is located on one side of the mop channel 21, the space inside the bucket body 3 located below the mop channel 21 is vacated. Therefore, external water enters the bucket body 3 from the mop channel 21, and the mop 1 is inserted into the mop channel 21 to clean the mop 1. Alternatively, the bucket lid 2 can be removed from the bucket body 3, and external water enters from the opening of the bucket body 3. The mop 1 is then inserted into the mop channel 21 to clean the mop 1.

[0264] The cleaning tool provided in this application embodiment saves space occupied by the airbag 42 in the bucket 3 by placing the airbag 42 on one side of the mop channel 21; moreover, since the space below the mop channel 21 in the bucket 3 is not occupied, water can be added in this space to clean the mop 1, which increases the way to clean the mop 1 and improves flexibility.

[0265] In the embodiment where the airbag 42 is disposed on one side of the mop channel 21, in conjunction with the first limiting structure 71, exemplarily, refer to... Figure 30 A first limiting structure 71 is disposed between the airbag 42 and the mop channel 21 to limit the airbag 42 to one side of the mop channel 21. Therefore, the first limiting structure 71 can more effectively restrict the movement space of the airbag 42 and improve the stability of the water absorption device 4.

[0266] For example, refer to Figure 31 The lower end of the first limiting structure 71 is connected to the inner bottom wall 33 of the barrel 3 to restrict the movement space of the airbag 42 in the first plane.

[0267] Figure 32 This is a top view of the assembly of the support partition 5, the first limiting structure 71, and the barrel 3 provided in the embodiments of this application. Figure 33 yes Figure 32 A 3D cross-section view from GG's perspective. Figure 34 yes Figure 33 A magnified view of a section at point G. Figure 35 This is another structural schematic diagram of the support partition 5 provided in the embodiments of this application.

[0268] refer to Figures 31 to 35The barrel body 3 is also provided with a support partition 5 for supporting the airbag 42. The support partition 5 is provided with an opening that matches the first water outlet valve 431, and the support partition 5 and the inner bottom wall 33 of the barrel body 3 form a receiving space to facilitate the discharge of the material in the airbag 42 into the barrel body 3.

[0269] Specifically, refer to Figure 31 A support partition 5 is disposed inside the barrel 3 and located below the airbag 42 to support the airbag 42. A first water outlet valve 431 on the airbag 42 is inserted into an opening on the support partition 5, allowing the contents of the airbag 42 to be discharged through the first water outlet valve 431 and the opening. (Reference) Figures 32 to 35 The bottom of the supporting partition 5 has a recessed area 5a with an inner wall 53. A receiving space is formed between the inner wall 53 of the recessed area 5a and the inner bottom wall 33 of the barrel 3, allowing the material discharged from the airbag 42 to be smoothly discharged into the barrel 3. It should be understood that a gap exists between the first water outlet valve 431 and the inner bottom wall 33 of the barrel 3 to facilitate the discharge of material from the airbag 42 into the barrel 3; this gap serves as part of the receiving space.

[0270] For example, the support partition 5 is movably disposed within the barrel body 3 to facilitate the removal and installation of the support partition 5.

[0271] For example, refer to Figure 35 The supporting partition 5 has a hollow structure. In this example, the hollow area of ​​the supporting partition 5 can be used as an opening on the supporting partition 5.

[0272] In order to drain the liquid from tank 3, refer to Figure 34 The side wall of the tank body 3 is provided with a water outlet 32, which is connected to the first water outlet valve 431 through the receiving space to facilitate the discharge of liquid from the air bladder 42 into the tank body 3. During the discharge process, the liquid in the air bladder 42 is discharged from the first water outlet valve 431 into the receiving space inside the tank body 3. Since the receiving space is connected to the water outlet 32, the liquid can flow smoothly to the water outlet 32 ​​and be discharged from the water outlet 32.

[0273] The above, combined with Figures 25 to 35 The structure of another cleaning tool with an airbag 42 provided in the embodiments of this application is described in detail.

[0274] The following, combined with Figures 36 to 48 The structure of the cleaning tool with a suction cylinder 44 and a movable plug 451 provided in the embodiments of this application will be described.

[0275] Figure 36 This is an exploded view of a cleaning tool with a suction cylinder 44 and a movable plug 451 provided in an embodiment of this application. Figure 37This is an exploded view of a water-absorbing device with a water-absorbing cylinder 44 and a movable plug 451 provided in an embodiment of this application. Figure 38 This is a schematic diagram of the structure of the barrel 4 provided in the embodiment of this application, which is equipped with a water suction cylinder 44 and a second limiting structure 72. Figure 39 This is a top view of a cleaning tool with a suction cylinder 44 and a movable plug 451 provided in an embodiment of this application. Figure 40 yes Figure 39 Cross-sectional view from the perspective of the middle HH. Figure 41 yes Figure 40 A magnified view of a section at point H.

[0276] refer to Figure 36 The cleaning tools include a mop 1 and a mop bucket. The mop bucket includes a mop channel 21, a bucket body 3, and a water absorption device 4. Exemplarily, the mop bucket also includes a bucket lid 2 connected to the bucket body 3, and the mop channel 21 is disposed on the bucket lid 2. For a detailed description of the mop 1, mop channel 21, bucket lid 2, and bucket body 3, please refer to the relevant descriptions above; further details will not be repeated here.

[0277] refer to Figures 36 to 38 The water suction device 4 includes a water inlet structure 41 and a power unit. The power unit includes a water suction cylinder 44 and a movable plug 451 that seals with the water suction cylinder 44. The water suction cylinder 44 is disposed inside the bucket body 3 and located on one side of the mop channel 21. (Reference) Figures 39 to 41 The movable plug 451 can move upward inside the suction cylinder 44. The first space 441 between the movable plug 451 and the lower end of the suction cylinder 44 gradually increases so that a negative pressure is formed in the first space 441 to generate suction and draw the liquid on the mop 1 into the suction cylinder 44.

[0278] refer to Figure 37 The water inlet structure 41 has a first opening 4111 at one end near the mop channel 21, through which liquid on the mop 1 can enter the water inlet structure 41.

[0279] In some embodiments, reference Figure 37 The water inlet structure 41 includes a water inlet section 411 and a first guide pipe 412. The water inlet section 411 is disposed adjacent to the mop channel 21, and a first opening 4111 is formed at one end of the water inlet section 411 near the mop channel 21. (Reference) Figure 37 , Figure 38 and Figure 41 One end 4122 of the first guide pipe 412 is connected to the water suction cylinder 44, and the other end of the first guide pipe 412 is connected to the water inlet 411. Thus, the water suction cylinder 44 and the water inlet 411 are connected through the first guide pipe 412.

[0280] For example, the first guide tube 412 can be a flexible tube.

[0281] Because the hose is flexible and easily deformable, for example, it is easy to bend, and it is convenient to install the water inlet structure 41 in the limited space of the bucket 3. Especially during the movement of the mop 1, the deformation of the first guide pipe 412 facilitates the smooth movement of the mop 1.

[0282] Figure 42 This is a schematic diagram showing the state of the movable plug 451 in the first extreme position of the suction cylinder 44 provided in the embodiment of this application. Figure 43 yes Figure 42 A magnified view of a section at point J. Figure 44 This is a schematic diagram showing the state of the movable plug 451 in the second extreme position of the suction cylinder 44 provided in the embodiment of this application. Figure 45 yes Figure 44 A magnified view of the area at point K.

[0283] In some embodiments, reference Figures 40 to 45 To increase the size of the first space 441 between the movable plug 451 and the lower end of the suction cylinder 44, the movable plug 451 can be moved downwards and then upwards. Specifically, the movable plug 451 can move downwards within the suction cylinder 44, causing the material in the first space 441 to be discharged and the first space 441 to gradually decrease; the movable plug 451 can also move upwards within the suction cylinder 44, causing the first space 441 to gradually increase, thereby creating a negative pressure within the first space 441 to generate suction.

[0284] Assume that before the movable plug 451 moves downward, the movable plug 451 is in the following position: Figure 43 At the upper end of the suction cylinder 44 shown, the first space 441 has the largest volume. Subsequently, the movable plug 451 moves downward within the suction cylinder 44, the material in the first space 441 is discharged, and the first space 441 gradually decreases in size. Figure 43 The state shown changes to Figure 41 As shown, ideally, the movable plug 451 can move to the position indicated. Figure 45 At the lower end of the suction cylinder 44 shown, the volume of the first space 441 is almost zero, and the material in the first space 441 is almost completely drained. Subsequently, the movable plug 451 moves upward within the suction cylinder 44, gradually increasing the size of the first space 441 to create a negative pressure, thereby generating suction. Figure 45 The state shown changes to Figure 41 As shown, ideally, the movable plug 451 can move to the position indicated. Figure 43 The upper part of the water-absorbing cylinder 44 shown has the largest volume in the first space 441.

[0285] It should be understood that Figure 43 and Figure 45The states of the movable plug 451 in the two extreme positions of the suction cylinder 44 shown are merely illustrative examples and should not be construed as limiting the embodiments of this application. The movable plug 451 in the extreme positions of the suction cylinder 44 can be flexibly designed according to actual conditions.

[0286] It should also be understood that the substance within the first space 441 may include air, or liquid (water) absorbed from the mop 1; in short, the substance within the first space 441 may include any substance that can be contained therein. If there is no liquid in the first space 441 (e.g., during the initial absorption of water), the substance discharged from the first space 441 mainly consists of air; if there is liquid in the first space 441 (e.g., liquid absorbed during the absorption process), the substance discharged from the first space 441 mainly consists of liquid.

[0287] In order to drain the material from the first space 441 inside the suction cylinder 44, in some embodiments, reference is made to... Figure 38 The lower end of the suction cylinder 44 is equipped with a second water outlet valve 433 for discharging the material in the first space 441. The second water outlet valve 433 only allows the material in the suction cylinder 44 to enter the barrel 3. That is to say, the second water outlet valve 433 is a one-way valve, which only allows the material in the first space 441 to be discharged into the barrel 3, and does not allow external materials to enter the first space 441 at this point.

[0288] As the movable plug 451 moves downward within the suction cylinder 44, the second water outlet valve 433 opens, and the substance (air and / or liquid) in the first space 441 is discharged from the second water outlet valve 433, reducing the volume of the first space 441. When the movable plug 451 begins to move upward within the suction cylinder 44, the second water outlet valve 433 closes, increasing the space within the first space 441 and decreasing the pressure, while the external atmospheric pressure remains unchanged, creating a negative pressure within the first space 441. Under the action of the pressure difference, a suction force is generated within the first space 441, drawing the liquid on the mop head 12 into the suction cylinder 44.

[0289] The cleaning tool provided in this application embodiment has a second water outlet valve 433 on the water suction cylinder 44. This valve serves two purposes: first, it can discharge the material in the first space 441 inside the water suction cylinder 44 to reduce the volume of the first space 441; second, it prevents external material from entering the first space 441 at the position of the second water outlet valve 433. This not only prevents the liquid in the barrel 3 from flowing back into the water suction cylinder 44, but also allows the first space 441 to have a relatively sealed environment as much as possible during the upward movement of the movable plug 451, which easily forms negative pressure and generates suction.

[0290] In some embodiments, reference Figure 38A second inlet valve 434 is provided at the connection point between the water inlet cylinder 44 and the water inlet structure 41. The second inlet valve 434 only allows substances inside the water inlet structure 41 to enter the water inlet cylinder 44. That is to say, the second inlet valve 434 is a one-way valve, which only allows substances inside the water inlet structure 41 to enter the water inlet cylinder 44, and does not allow substances inside the water inlet cylinder 44 to enter the water inlet structure 41.

[0291] As the movable plug 451 moves downward within the suction cylinder 44, the second outlet valve 433 opens and the second inlet valve 434 closes. The substance (air and / or liquid) in the first space 441 of the suction cylinder 44 is discharged from the second outlet valve 433, reducing the volume of the first space 441. When the movable plug 451 begins to move upward within the suction cylinder 44, the second outlet valve 433 closes, and the second inlet valve 434 remains closed, essentially creating a sealed environment within the first space 441. The volume within the first space 441 increases, and the pressure decreases, while the external atmospheric pressure remains constant, creating a negative pressure within the first space 441. Under the action of the pressure difference, suction is generated within the first space 441, drawing liquid from the mop head 12. The second inlet valve 434 opens, and liquid enters the suction cylinder 44 from the water inlet structure 41.

[0292] The cleaning tool provided in this application embodiment, combined with the design of the second water outlet valve 433 and the second water inlet valve 434, allows the movable plug 451 to move upward in the water suction cylinder 44, so that the first space 441 gradually increases and a better sealing environment is formed in the first space 441. This is conducive to the rapid and better formation of negative pressure in the first space 441, resulting in better suction.

[0293] In this embodiment, the moving direction of the movable plug 451 within the water suction cylinder 44 can be the same as the moving direction of the mop 1 to improve the user experience.

[0294] In some embodiments, reference Figure 40 and Figure 45 As the mop 1 moves downward, the movable plug 451 moves downward inside the suction cylinder 44, and the material in the first space 441 is discharged through the second water outlet valve 433, and the first space 441 gradually decreases. As the mop 1 moves upward, the movable plug 451 moves upward inside the suction cylinder 44, and the first space 441 gradually increases so that a negative pressure is formed in the first space 441 to generate suction.

[0295] In other words, when the mop 1 moves downward, the movable plug 451 also moves downward within the water suction cylinder 44; when the mop 1 moves upward, the movable plug 451 also moves upward within the water suction cylinder 44, thus achieving water absorption by the mop 1.

[0296] The cleaning tool provided in this application embodiment, whether operated by one hand or two hands (one hand operates the movable plug 451 and the other hand operates the mop 1), makes the operation of the user relatively simple and convenient, and improves the user experience, by making the movement of the movable plug 451 in the water suction tube 44 in the same direction as the movement of the mop 1.

[0297] It should be understood that the relationship between the moving direction of the movable plug 451 in the water suction cylinder 44 and the moving direction of the mop 1 described above is merely illustrative and should not be construed as limiting the embodiments of this application. For example, the moving direction of the movable plug 451 in the water suction cylinder 44 and the moving direction of the mop 1 may also be different. For instance, as the movable plug 451 moves upward in the water suction cylinder 44, the mop 1 may move upward, downward, or up and down, and the mop head 12 of the mop 1 will fully contact the first opening 4111 of the water inlet structure 41 to absorb the liquid on the mop head 12.

[0298] To further simplify operations and improve user experience, please refer to... Figures 40 to 45 As the mop 1 moves downward, the mop 1 acts on the movable plug 451 to drive the movable plug 451 to move downward within the water suction cylinder 44.

[0299] It should be understood that the mop 1 acts on the movable plug 451, either by the mop 1 acting directly on the movable plug 451 or by the mop 1 acting indirectly on the movable plug 451 through other components. This application embodiment does not make any limitation.

[0300] The following is a detailed description of how the mop 1 indirectly acts on the movable plug 451 through other components.

[0301] In some embodiments, reference Figure 37 , Figure 40 and Figure 41 The movable plug 451 is connected to a drive unit 452. During the downward movement of the mop 1, the mop 1 drives the movable plug 451 to move downward in the water suction cylinder 44 through the drive unit 452.

[0302] It should be understood that the drive unit 452 and the movable plug 451 can be directly connected or indirectly connected through other components. This application embodiment does not impose any limitations.

[0303] In some embodiments, reference Figure 40 and Figure 41 The drive unit 452 is located on one side of the water suction cylinder 44 and below the mop channel 21. During the water suction process, the mop 1 moves downward, which in turn acts on the drive unit 452, causing the movable plug 451 to move downward within the water suction cylinder 44.

[0304] In this embodiment, to facilitate the connection between the drive unit 452 and the movable plug 451, reference is made, by way of example. Figure 37 The movable plug 451 and the drive unit 452 are connected by the connecting arm 453. When the mop 1 moves downward, it acts on the drive unit 452, which drives the connecting arm 453 to move, and the connecting arm 453 drives the movable plug 451 to move.

[0305] Regarding connecting arm 453, see reference Figure 44 and Figure 45 The connecting arm 453 is movably inserted through the lid 2, and when the movable plug 451 moves downward to the limit position of the suction cylinder 44, the upper end of the connecting arm 453 protrudes above the lid 2. In this way, during the movement of the movable plug 451 within the suction cylinder 44, the connecting arm 453 can move within the suction cylinder 44 without affecting the sealing fit between the movable plug 451 and the suction cylinder 44. The design is simple and easy to implement. Furthermore, the portion of the connecting arm 453 protruding from the lid 2 allows the user to pull up the connecting arm 453 to move the movable plug 451 upward within the suction cylinder 44, facilitating user operation.

[0306] For example, refer to Figure 37 The connecting arm 453 has an inverted U-shaped structure. In other examples, the connecting arm 453 can be any other shape, and there are no limitations here.

[0307] Figure 46 This is another exploded view of the water suction device 4 with a water suction cylinder 44 and a movable plug 451 provided in the embodiments of this application. Figure 47 yes Figure 39 Cross-sectional view from the perspective of the middle II. Figure 48 yes Figure 47 A magnified view of the area at point L.

[0308] In the embodiments described above where the movable plug 451 is driven by the drive unit 452, during the process of the mop 1 moving downwards to drive the drive unit 452, in order to improve the stability of the movement process of the drive unit 452, in some embodiments, reference is made to... Figure 38 , Figures 46 to 48 The bucket body 3 is provided with a second limiting structure 72 for restricting the movement of the drive unit 452 on a first plane. The first plane is perpendicular to the moving direction of the mop 1. The second limiting structure 72 is slidably connected to the drive unit 452 in the moving direction of the mop 1. During the process of the mop 1 moving and driving the drive unit 452 to move, the drive unit 452 slides relative to the second limiting structure 72.

[0309] Therefore, the cleaning tool provided in this application embodiment can improve the stability of the drive unit 452 during movement by setting a second limiting structure 72 for limiting the activity space of the drive unit 452 in a first plane perpendicular to the moving direction of the mop 1, thereby improving the stability of the water absorption device 4.

[0310] For example, refer to Figure 38 The second limiting structure 72 is a columnar structure. In other examples, the second limiting structure 72 may also be other structures such as plates, and this application embodiment does not impose any limitations.

[0311] For example, refer to Figure 37 and Figure 46 The drive unit 452 is provided with a second limiting port 4521 for the second limiting structure 72 to be inserted, and the second limiting port 4521 is slidably engaged with the second limiting structure 72.

[0312] This application embodiment does not limit the number of the second limiting structure 72 and the second limiting port 4521. For example, the number of the second limiting structure 72 and the second limiting port 4521 can be 1, 2, etc.

[0313] In some embodiments, reference Figure 37 and Figure 46 The drive unit 452 has two second limiting ports 4521 arranged opposite each other along the first direction, for reference. Figure 38 and Figure 46 Inside the barrel body 3, two second limiting structures 72 are arranged opposite each other along the first direction, corresponding one-to-one with the two second limiting ports 4521. The second limiting structures 72 are inserted into the corresponding second limiting ports 4521.

[0314] The cleaning tool provided in this application embodiment, by setting two second limiting structures 72 for limiting the activity space of the drive part 452 in a first plane perpendicular to the moving direction of the mop 1, and setting two corresponding second limiting ports 4521 on the drive part 452, can make the drive part 452 be subjected to uniform force and improve the stability of the movement process of the drive part 452.

[0315] After the movable plug 451 moves downward within the suction cylinder 44, in order to achieve the upward movement of the movable plug 451, in some embodiments, reference is made to 46 to... Figure 48 An elastic reset member 8 is provided inside the barrel body 3. The elastic reset member 8 is connected to the movable plug 451 so as to drive the movable plug 451 to move upward.

[0316] The cleaning tool provided in this application embodiment can automatically move the movable plug 451 upward to reset through the elastic reset member 8, avoiding the need for other additional operations to move the movable plug 451 upward, simplifying user operation and improving user experience.

[0317] It should be understood that the elastic reset element 8 and the movable plug 451 can be directly connected or indirectly connected through other components.

[0318] In cases where the elastic reset member 8 and the movable plug 451 are indirectly connected via other components, in some embodiments, refer to... Figures 46 to 48 The barrel body 3 is provided with an elastic reset member 8, which is connected to the drive unit 452 so as to drive the movable plug 451 to move upward through the drive unit 452.

[0319] In other words, the elastic reset member 8 is connected to the movable plug 451 through the drive part 452. During the downward movement of the mop 1, the elastic reset member 8 is compressed to generate elastic force. During the upward movement of the mop 1, the drive part 452 moves upward under the elastic force of the elastic reset member 8 and drives the movable plug 451 to move upward.

[0320] For example, refer to Figures 46 to 48 In an embodiment where a second limiting structure 72 is provided inside the barrel body 3, the elastic reset member 8 is connected to the driving part 452 and sleeved outside the second limiting structure 72. Thus, the second limiting structure 72 can support the elastic reset member 8, preventing it from twisting after deformation.

[0321] In cases where the elastic reset member 8 is directly connected to the movable plug 451, in some embodiments (not shown in the figures), the elastic reset member 8 may be disposed between the lower end of the suction cylinder 44 and the movable plug 451. When an external force is applied (e.g., a force applied to the movable plug 451 by a user via a mop 1 or other component), as the movable plug 451 moves downward within the suction cylinder 44, the elastic reset member 8 is compressed, generating an elastic force. After the external force is removed, the movable plug 451 moves upward under the elastic force of the elastic reset member 8.

[0322] It should be understood that the above-described method of achieving automatic upward movement of the movable plug 451 through the elastic reset member 8 is merely illustrative and does not constitute any limitation in this application embodiment. In other examples, for instance, in the embodiment where the connecting arm 453 passes through the bucket lid 2 and the upper end of the connecting arm 453 is exposed on the bucket lid 2 when the movable plug 451 moves downward to the extreme position of the water suction cylinder 44, the user can lift the portion of the connecting arm 453 exposed on the bucket lid 2 to drive the movable plug 451 upward.

[0323] It should also be understood that the structure described above, which enables the movement of the movable plug 451 within the suction tube 44 by moving the mop 1, is merely illustrative and should not be construed as limiting the embodiments of this application. In other examples (not shown in the figures), the movement of the movable plug 451 may not be required by moving the mop 1. For example, a connecting rod may be provided above the movable plug 451, with the connecting rod passing through and protruding from the lid 2. When the user presses the connecting rod, the connecting rod acts on the movable plug 451, causing the movable plug 451 to move downward within the suction tube 44. When the user lifts the connecting rod, the movable plug 451 can move upward within the suction tube 44.

[0324] Regarding the cleaning of the cleaning tools, including the aforementioned power unit 44 and the movable plug 451, the mop 1 can be cleaned in various ways.

[0325] In some embodiments, external water can be introduced into the water inlet structure 41 and discharged from the first opening 4111 of the water inlet structure 41 by referring to the second guide pipe 24, the water inlet 23 provided on the bucket lid 2 and the connecting channel 25, so as to wet the mop head 12 and clean the mop 1.

[0326] In other embodiments, since the water suction tube 44 is located on one side of the mop channel 21, the space inside the bucket body 3 located below the mop channel 21 is left empty. Therefore, external water source enters the bucket body 3 from the mop channel 21, and the mop 1 is inserted into the mop channel 21 to clean the mop 1. Alternatively, the bucket cover 2 is removed from the bucket body 3, and external water source enters from the opening of the bucket body 3. The mop 1 is inserted into the mop channel 21 to clean the mop 1.

[0327] The above, combined with Figures 1 to 48 The present application provides a detailed description of a cleaning tool that generates suction by increasing the space within a power unit, according to an embodiment of the present application.

[0328] The following, combined with Figures 49 to 59 This application provides a detailed description of the cleaning tool that generates suction through a pump in a power unit, according to embodiments of the present application.

[0329] Figure 49 This is an exploded view of a cleaning tool with a pump 47 provided in an embodiment of this application. (Reference) Figure 49 The cleaning tools include a mop 1 and a mop bucket. The mop bucket includes a mop channel 21, a bucket body 3, and a water suction device 4. The water suction device 4 is located inside the bucket body 3 and includes a pump 47. The pump 47 is used to generate suction to draw out liquid from the mop 1 as it moves through the mop channel 21 within the bucket body 3.

[0330] For example, the mop bucket also includes a lid 2 connected to the bucket body 3, and a mop channel 21 is disposed on the lid 2. For a detailed description of the mop 1, mop channel 21, lid 2, and bucket body 3, please refer to the description above; further details will not be repeated here.

[0331] During the water absorption process, the mop 1 can move upward, downward, or up and down; this application embodiment does not impose any limitations.

[0332] The cleaning tool provided in this application embodiment, by setting a water suction device 4 with a pump 47 to generate suction in the bucket 3, allows the user to move the mop 1 without too much force, so that the liquid on the mop 1 can be sucked up by the suction generated by the pump 47, which improves the user experience; moreover, since the design of the pump 47 is relatively mature, the structural design of the entire water suction device 4 can be simplified.

[0333] refer to Figure 49 The water suction device 4 also includes a water inlet structure 41, which is located adjacent to the mop channel 21 and connected to the pump 47, so as to draw liquid on the mop 1 from the water inlet structure 41 into the pump 47 during the movement of the mop 1. A first opening 4111 is formed at one end of the water inlet structure 41 near the mop channel 21, through which liquid on the mop 1 can enter the water inlet structure 41.

[0334] In some embodiments, reference Figure 49 The water inlet structure 41 includes a water inlet section 411 and a first guide pipe 412. The water inlet section 411 is disposed adjacent to the mop channel 21, and a first opening 4111 is formed at one end of the water inlet section 411 near the mop channel 21. One end of the first guide pipe 412 is connected to the pump 47, and the other end is connected to the water inlet section 411, thereby enabling communication between the pump 47 and the water inlet section 411 through the first guide pipe 412.

[0335] For example, the first guide tube 412 can be a flexible hose. In this way, due to the flexibility and deformability of the hose, for example, it is easy to bend, which facilitates the installation of the water inlet structure 41 and the pump 47 within the limited space of the tank 3.

[0336] In some embodiments, a touch control is provided on the pump 47 for turning the pump 47 on or off, and when the pump 47 is turned on, the pump 47 generates suction.

[0337] refer to Figure 49 The touch control includes a transmission assembly 482; and the pump 47 includes a pump body 471, an impeller disposed within the pump body 471, and a drive shaft 473, the impeller being mounted on the drive shaft 473, the drive shaft 473 extending out of the pump body 471, wherein the transmission assembly 482 is connected to the drive shaft 473 to drive the drive shaft 473 to rotate in order to drive the impeller to rotate, thereby turning on the pump 47 and generating suction.

[0338] The cleaning tool provided in this application embodiment drives the drive shaft 473 to rotate via the transmission component 482, thereby driving the impeller to rotate. Compared with driving the impeller via a motor, this saves energy and reduces costs.

[0339] In this embodiment, the transmission component 482 can be driven by external force, or by the movement of the mop 1. This embodiment does not impose any limitations.

[0340] In some embodiments, the mop 1 is provided with a drive device for driving the transmission assembly 482 to ultimately drive the impeller to rotate when the mop 1 moves.

[0341] The cleaning tool provided in this application embodiment, by setting a drive device on the mop 1, uses the movement of the mop 1 to drive the impeller in the pump 47 to rotate, reduces the additional parts and operations caused by using external force to drive the transmission assembly 482, reduces the complexity of the structure and operation, and improves the user experience.

[0342] In some embodiments, a drive device is provided on the mop head 12 of the mop 1.

[0343] Figure 50 This is a schematic diagram of the assembly of a water suction device 4 with a pump 47, a bucket lid 2, and a mop 1 provided in the embodiments of this application. Figure 51 yes Figure 50 A magnified view of a section at point M.

[0344] In some embodiments, reference Figure 50 and Figure 51 The drive unit includes a rack 12c that meshes with the transmission assembly 482.

[0345] In one example, reference Figure 50 and Figure 51 The rack 12c is disposed on the back side 12b of the mop head 12. The back side 12b of the mop head 12 is the side of the mop plate 121 away from the wiping object 122, and the wiping object 122 is mounted on the front side of the mop plate 121.

[0346] In this example, to simplify the design, refer to Figure 50 and Figure 51 Pump 47 can be located on one side of the back 12b of mop head 12.

[0347] In other examples, for instance, the rack 12c may also be positioned on the front of the mop head 12, with the front of the mop head 12 opposite to the back surface 12b. In this example, for design simplicity, the pump 47 may be positioned on one side of the front of the mop plate 12.

[0348] Regarding the transmission assembly 482, in some embodiments, refer to Figures 49 to 51The transmission assembly 482 includes a first transmission member 4821 and a second transmission member 4822. The first transmission member 4821 meshes with the rack 12c, and the second transmission member 4822 is connected to both the first transmission member 4821 and the drive shaft 473. For example, the second transmission member 4822 is fixedly connected to both the first transmission member 4821 and the drive shaft 473. Alternatively, the second transmission member 4822 is driven by both the first transmission member 4821 and the drive shaft 473, and a rack or gear matching the second transmission member 4822 can be mounted on the drive shaft 473.

[0349] For example, the first transmission element 4821 is a gear.

[0350] For example, the second transmission element 4822 is a transmission belt.

[0351] The embodiments of this application do not limit the number of transmission components 482. For example, the number of transmission components 482 may be 1 or 2.

[0352] In some embodiments, reference Figure 49 and Figure 50 The touch control includes two transmission components 482. The mop head 12 of the mop 1 is provided with racks 12c that mesh with the transmission components 482 on both sides along the width direction. The two transmission components 482 are respectively connected to the two ends of the drive shaft 473.

[0353] The cleaning tool provided in this application embodiment, by setting two transmission components 482, can make the pump 47 receive force evenly and improve the stability of the water suction device 4.

[0354] In this embodiment of the application, the transmission component 482 may be disposed on the mop bucket.

[0355] In some embodiments, reference Figure 51 The transmission assembly 482 is disposed on the bucket lid 2. Exemplarily, the first transmission member 4821 in the transmission assembly 482 is disposed on the bucket lid 2 to realize the connection of the transmission assembly 482 on the bucket lid 2.

[0356] In other embodiments, the transmission assembly 482 may also be disposed on the barrel 3 or on any component mounted on the barrel 3, and this application embodiment does not impose any limitation.

[0357] In this embodiment, pump 47 is disposed on the mop bucket. In some embodiments, reference is made to... Figure 51 Pump 47 is connected to bucket lid 2. For example, pump body 471 is connected to bucket lid 2 via third connector 27 to achieve connection between pump 47 and bucket lid 2.

[0358] As mentioned earlier, the mop 1 needs to be washed before it can absorb water. In embodiments where the water-absorbing device 4 generates suction through the pump 47, the mop 1 can be washed in various ways.

[0359] In some embodiments, the conventional method of cleaning the mop 1 can be referred to. For example, external water enters the bucket 3 through the mop channel 21, and the mop 1 is inserted into the mop channel 21 to clean the mop 1. Alternatively, the bucket cover 2 can be removed from the bucket 3, external water enters through the opening of the bucket 3, and the mop 1 is inserted into the mop channel 21 to clean the mop 1.

[0360] In other embodiments, an external water source can be introduced into the water inlet structure 41 and discharged from the water inlet structure 41 through a second guide pipe 24 of an external device. The discharged water wets the mop head 12 to clean the mop head 12, thereby achieving the cleaning of the mop 1.

[0361] Figure 52 This is another structural schematic diagram of the assembly of the water suction device 4 with pump 47, bucket lid 2 and mop 1 provided in the embodiments of this application. Figure 53 yes Figure 52 A magnified view of a portion of point N in the middle. Figure 54 This is another structural schematic diagram of the assembly of the water suction device 4 with pump 47, bucket lid 2 and mop 1 provided in the embodiments of this application. Figure 55 yes Figure 54 A magnified view of a portion of point P in the middle.

[0362] refer to Figures 52 to 55 The mop bucket is provided with a second guide pipe 24. One end of the second guide pipe 24 is used to connect to an external water source, and the other end is connected to the water inlet structure 41, so as to introduce the external water source into the water inlet structure 41 and discharge it from the first opening 4111 of the water inlet structure 41 to clean the mop 1 inserted into the mop channel 21. Exemplarily, the other end of the second guide pipe 24 is connected to the water inlet part 411 of the water inlet structure 41. The end of the water inlet part 411 near the mop channel 21 has a first opening 4111, so as to introduce the external water source into the water inlet part 411 and discharge it from the first opening 4111 of the water inlet part 411.

[0363] During the water intake process, the mop 1 is inserted into the mop channel 21 and preferably moved downward to the limit position. The external water source enters the water intake structure 41 from the second guide pipe 24 and is discharged from the first opening 4111 of the water intake structure 41. The discharged water wets the mop head 12 to clean the mop head 12.

[0364] In the embodiment described above where a second guide pipe 24 is provided on the mop bucket, the second guide pipe 24 can be provided on the bucket body 3 or on the bucket lid 2. The structure of the second guide pipe 24 being provided on the bucket lid 2 will be described in detail below.

[0365] In one example, reference Figure 9 , Figures 52 to 53 The bucket lid 2 is provided with an inlet 23 for connecting to an external water source and penetrating through the bucket lid 2 (e.g., Figure 9 As shown), a second guide pipe 24 is provided on the inner top wall of the bucket lid 2 (as shown). Figure 53 As shown), the second guide pipe 24 connects the water inlet 23 and the water inlet structure 41. Exemplarily, the second guide pipe 24 connects the water inlet 23 and the water inlet section 411 of the water inlet structure 41.

[0366] During the water intake process, external water enters the second guide pipe 24 from the water inlet 23, enters the water intake structure 41 (e.g., the water intake part 411 of the water intake structure 41) through the second guide pipe 24, and is discharged from the first opening 4111 of the water intake structure 41. The discharged water wets the mop head 12 to clean the mop head 12.

[0367] To facilitate connection to an external water source, in one example, refer to... Figure 9 and Figure 55 The bucket lid 2 is provided with a connecting channel 25 for connecting an external hose. The connecting channel 25 extends out of the bucket lid 2 and is connected to the water inlet 23. In this way, by connecting the external hose through the connecting channel 25, external water can enter the water inlet 23 through the external hose and finally be discharged from the first opening 4111 of the water inlet structure 41 to wet the mop head 12 and clean the mop head 12.

[0368] In the above-described structure where water is introduced from the water inlet structure 41 via the second guide pipe 24 to clean the mop 1, in order to ensure smooth water intake, in some embodiments, refer to... Figure 15 and Figure 55 When the mop 1 extends into the bucket 3 through the mop channel 21 with the maximum travel distance, at least a portion of the first opening 4111 of the water inlet structure 41 is located above the mop head 12 of the mop 1.

[0369] For example, the first opening 4111 is located above the mop head 12 of the mop 1.

[0370] In this embodiment of the application, the relationship between the first opening 4111 of the water inlet structure 41 and the size design of the mop head 12 is as follows: the difference between the size of the first opening 4111 in the first direction and the width of the mop head 12 of the mop 1 is less than a threshold value, and the first direction is parallel to the width direction of the mop head 12.

[0371] In one example, the first opening 4111 has the same dimension in the first direction as the width of the mop head 12.

[0372] For a detailed description of the design of the first opening 4111 of the water inlet structure 41 and the mop head 12, please refer to the relevant description above, which will not be repeated here.

[0373] Figure 56 This is another exploded view of the cleaning tool with pump 47 provided in the embodiments of this application. Figure 57 These are exploded views of the water suction device 4 with pump 47 provided in the embodiments of this application from two angles. Figure 58 This is a schematic diagram of the assembly of a water suction device 4 with a pump 47, a bucket lid 2, and a mop 1 provided in the embodiments of this application. Figure 59 yes Figure 58 Exploded view. (and) Figures 49 to 55 The difference in the corresponding embodiments is that, Figures 56 to 59 In the corresponding embodiment, the pump 47 is controlled to turn on or off by controlling the motor.

[0374] refer to Figure 56 and Figure 57 The cleaning tools include a mop 1 and a mop bucket. The mop bucket includes a mop channel 21, a bucket body 3, and a water suction device 4. The water suction device 4 is located inside the bucket body 3 and includes a pump 47. The pump 47 is used to generate suction to draw out liquid from the mop 1 as it moves through the mop channel 21 within the bucket body 3.

[0375] For example, refer to Figure 56 The mop bucket also includes a bucket lid 2 connected to the bucket body 3, and a mop channel 21 is provided on the bucket lid 2.

[0376] For example, refer to Figure 57 The pump 47 includes a pump body 471, which contains various components for generating suction. For example, the pump body 471 contains a motor and an impeller. The motor drives the impeller to rotate, thereby activating the pump 47 and generating suction. The pump body 471 has a water outlet structure 472 for discharging the liquid drawn into the pump 47.

[0377] For example, refer to Figure 57 The water suction device 4 also includes a water inlet structure 41, which is located adjacent to the mop channel 21 and connected to the pump 47, so as to draw liquid from the mop 1 into the pump 47 during the movement of the mop 1. The end of the water inlet structure 41 near the mop channel 21 has a first opening 4111, through which liquid from the mop 1 can enter the water inlet structure 41.
