[0045] Embodiment 1

[0046] like Figure 1 , Figure 2 As shown, the present application provides a dehydration device, including: a water squeezing frame 401, an extrusion member 402, and a smoothing mouth 403;

[0047] The extrusion member 402 includes an extrusion frame, which includes a crossbeam opposite to the water squeezing frame and two fixing parts connected to both ends of the crossbeam and arranged opposite to each other. The ends of the two fixing parts away from the crossbeam are rotatably connected to the water squeezing frame 401, and a groove 403 is formed between the crossbeam, the two fixing parts and the water squeezing frame 401.

[0048] The extrusion piece 402 is arranged opposite to the water squeezing frame 401 , and is rotatably connected to the water squeezing frame 401 to form a groove 403 between the extrusion piece 402 and the water squeezing frame 401 ; the extrusion piece 402 is connected to the water squeezing frame 401 by two fixing parts to squeeze the mop head 200 entering the groove 403 .

[0049] Specifically, the extrusion frame 402 is a U-shaped frame composed of a crossbeam and two oppositely arranged fixed parts connected at both ends of the crossbeam, wherein the two fixed parts are integrally formed with the crossbeam, and the ends of the two fixed parts away from the crossbeam are connected to the water squeezing frame 401, thereby forming a complete groove 403 of one end of the water squeezing frame 401-fixed part-crossbeam-fixed part-the other end of the water squeezing frame 401, that is, the crossbeam, the two fixed parts, and the water squeezing frame 401 together constitute the boundary of the groove 403.

[0050] Optionally, the extrusion piece 402 is rotatably connected to the water squeezing frame 401 through two fixed parts connected and arranged oppositely at the two ends of the crossbeam. Two symmetrical fixed positions are correspondingly arranged at the two ends of the water squeezing frame 401. The fixed positions have installation positions corresponding to the shape and size of the fixed parts. The fixed parts and fixed positions are opposite to each other to form a pair of rotating connection pairs. The above-mentioned installation positions include grooves, arc steps, convex ridges, etc. The installation position provides a guide for the rotation connection of the fixed part, and at the same time improves the strength and stability of the rotation pair and the rotation connection.

[0051] Specifically, Figure 5 As shown, the fixing part and the fixing position are a pair of connecting plates, and the fixing part and the fixing position are provided with axial holes of equal diameter at the axis centers, and each set of rotating pairs includes a fixing part, a fixing position and an axis cover 503, wherein a fixing shaft is provided on the axis cover 503, and the diameter of the fixing shaft matches the diameter of the above-mentioned axis hole, so that the fixing shaft can pass through the axis holes on a pair of connecting plates that match each other at both ends of the extrusion member 402 and the water squeezing frame 401, thereby forming a rotating pair between the extrusion member 402 and the water squeezing frame 401, and thereby realizing rotational connection between the extrusion member 402 and the water squeezing frame 401.

[0052] Optionally, the length of the fixed shaft on the shaft cover 503 is slightly longer than the sum of the thickness of the fixed part and the fixed position, so that it can pass through the shaft holes on a pair of connecting plates that cooperate with each other at both ends of the extrusion piece 402 and the water squeezing frame 401, and the relative position of the shaft cover 503 is fixed by buckling to ensure the connection stability of the rotating connection pair. Among them, the fixed shaft is a hollow shaft with thin-walled characteristics, and the fixed shaft has a certain elasticity, and one end passing through the above-mentioned shaft hole is an open end. A group of notches extending along the height direction of the shaft wall are opened on the hollow shaft wall of the fixed shaft, so that a plurality of annular elastic arms are formed, and at the same time, a group of buckles or protrusions are arranged on the outer side of one end of the hollow shaft wall of the fixed shaft passing through the above-mentioned shaft hole, and the highest point of the buckle or protrusion is greater than the diameter of the above-mentioned shaft hole. Through the above structure, when the fixed shaft enters the above-mentioned shaft hole, the end of the fixed shaft passing through the above-mentioned shaft hole is compressed by the inner wall of the shaft hole to cause elastic deformation in the direction of the axis center, and the outer diameter of the fixed shaft buckle or protrusion is less than or equal to the inner diameter of the shaft hole, so that it can pass through the shaft hole. When the fixed shaft passes through the above-mentioned shaft hole, one end of the fixed shaft passing through the above-mentioned shaft hole is affected by the rebound force to restore the original outer diameter size, and is clamped with the outer surface of the connecting plate through the above-mentioned buckle or protrusion. The above-mentioned buckle or protrusion prevents the fixed shaft from exiting the shaft hole, thereby ensuring that the fixed shaft maintains the above-mentioned passing position.

[0053] Optionally, the stroking opening 403 is a floating opening, and the shape of the stroking opening 403 is similar to that of the mop head 200, and the two can cooperate with each other. Exemplarily, the outer dimensions of the stroking opening 403 are slightly larger than the cross-sectional dimensions of the mop head 200 formed along the short side of the wiping surface, and the length-to-width ratio of the stroking opening 403 is similar to the length-to-width ratio of the cross-sectional dimensions of the mop head 200 formed along the short side of the wiping surface. In addition, the upper portion of the stroking opening 403 also has a U-shaped groove for accommodating the mop rod 100. Furthermore, when the mop head 200 is parallel to the stroking opening 403, it can pass through the stroking opening 403 by radial movement. At this time, most of the outer surface of the mop head maintains a certain distance from the stroking opening 403 and does not directly contact the stroking opening 403. When the stroking head 400 is in a high position, the mop head 200 is separated from the stroking mouth 403. When the stroking head 400 moves from a high position to a low position, the extrusion member 402 contacts the mop head 200 and generates relative movement, thereby generating friction. The component force of the generated friction force drives the extrusion member 402 to complete a forced rotation through the rotating connection pair, thereby reducing the plane distance between the extrusion member 402 and the water squeezing frame 401, reducing the area of ​​the formed stroking mouth 403, and increasing the corresponding squeezing force, thereby enhancing the single dehydration effect of the wipe.

[0054] In addition, when the stroking mouth 403 moves from a low position to a high position, the extrusion member 402 and the mop head 200 produce a relative movement in the opposite direction to the above-mentioned direction, and the friction force acting on the extrusion member 402 is opposite to the direction, so that the extrusion member 402 rotates in the opposite direction, so that the area of ​​the stroking mouth 403 formed by the extrusion member 402 and the water squeezing rack 401 is increased, making the return of the stroking mouth 400 in the reset condition without dehydration more labor-saving and smooth.

[0055] Optional, such as Figure 5 As shown, a limiting block 417 is provided on the top of the connecting disk of the extrusion piece 402, and a group of two limiting baffles are provided at the corresponding position of the water squeezing frame 401. Through the cooperation of the limiting block 417 and the group of limiting baffles, the extrusion piece 402 is approximately vertical to the plane of the mop head 200 at the extreme position of reverse rotation, and the minimum area of ​​the stroking mouth 403 is controlled when the mop head 200 enters the stroking mouth 403, so as to avoid excessive rotation of the extrusion piece 402, resulting in excessive downward resistance of the mop head 200, which in turn causes a situation where the operation force is large and it is difficult to use.

[0056] Further, such as Figure 2 , Figure 6 , Figure 7 As shown, the number of the extrusion members 402 is one or more, wherein, when the number of the extrusion members 402 is multiple, the multiple extrusion members 402 are arranged opposite to the water squeezing frame 401 to form a groove 403 between the multiple extrusion members 402 and the water squeezing frame 401, and the multiple extrusion members 402 rotate to squeeze the mop head 200 entering the groove 403.

[0057] Optionally, the stroking head 400 includes a first squeezing frame 411 and a second squeezing frame 412 that are rotatably arranged on both sides of the squeezing frame 401, and the first squeezing frame 411 and the second squeezing frame 412 are arranged in parallel up and down, and the second squeezing frame 412 is arranged on both sides of the squeezing frame in the same connection mode as the first squeezing frame 411, so that a floating second squeezing opening is formed between the squeezing frame 401 and the second squeezing frame 412. When the mop head 200 rotates to be parallel to the squeezing opening 403 and then penetrates the first squeezing opening and the second squeezing opening, the first squeezing frame 411 and the second squeezing frame 412 rub against the wiping surface of the mop head 200, driving the first squeezing frame 402 and the second squeezing frame 412 to rotate, thereby reducing the area of ​​the first squeezing opening and the second squeezing opening, and gradually reducing the distance between the first squeezing opening and the second squeezing opening and the wiping surface of the mop head 200, and gradually increasing the squeezing force, thereby enhancing the single dehydration effect of the wiped object. The arrangement of the upper and lower double extrusion racks enables the second extrusion rack 412 to further adaptively dehydrate the wipes based on the dehydration of the first extrusion rack 411, and the dehydration effect is improved compared with the arrangement of a single extrusion rack.

[0058] Optionally, the same limit block 417, shaft cover 503, and limit baffle as described above are also provided at the connection between the second extrusion frame 412 and the water squeezing frame 401, and the above structures or components appear in pairs. In addition, the rotation of the second extrusion frame 412 and the first extrusion frame 411 is independent rotation, so that the second extrusion frame 412 and the first extrusion frame 411 can adapt to different heights or concave and convex parts of the wiping surface on the mop head 200, thereby improving the dehydration efficiency and extending the service life of the wiping surface.

[0059] Further, such as Figure 4 As shown, the extrusion member 402 further includes a wiper portion 416 , which is located on a side of the cross beam opposite to the water squeezing frame 401 and is used for scraping the mop head 200 .

[0060] The width of the wiper portion 416 is consistent with the width of the rubbing mouth 403, and the wiper portion 416 is the portion on the cross beam of the extrusion member 402 that is closest to the water squeezing frame 401, that is, during the extrusion operation, the wiper portion 416 is the portion that is most closely in direct contact with the wiping surface on the mop head 200, and the wiper portion 416 provides the most important extrusion and dehydration capability for the extrusion member 402.

[0061] Optionally, a plurality of extrusion members 402 are each provided with a scraping portion 416 to achieve co-extrusion and scraping of multiple layers in a single dehydration stroke of the mop head, thereby ensuring a dehydration effect on the wiping surface.

[0062] In a preferred embodiment, the wiper portions 416 on the multiple extrusion racks are arranged in steps. The wiper portion 416 that first contacts the wiping surface on the mop head 200 has a relatively low height, and the height of the wiper portion 416 that contacts subsequently gradually increases, so as to achieve a gradual extrusion pressure on the wiping surface. At the same time, when the mop head enters the stroking mouth 403 for dehydration, a balanced pressure is provided in the direction of movement, which helps the mop head maintain parallel movement in the stroking mouth 200, improves the smoothness of the mop head 200 entering the stroking head 400, ensures the linear and smooth change of pressure during the extrusion and dehydration process, and enhances the user experience.

[0063] Optionally, a plurality of openings or slots are provided on the crossbeam of the extrusion frame, and the slots are used to timely discharge the liquid released by the extrusion dehydration to prevent the released liquid from being sucked into the mop head again.

[0064] Further, such as Figure 5 As shown, the wiper portion 416 includes a wiper strip or blade.

[0065] The second extrusion frame 412 and the wiping portion 416 of the first extrusion frame 411 are both provided with at least one scraping strip or scraper blade 511, which is connected to the crossbeam of the extrusion frame for scraping the wiping surface to achieve the technical effect of scraping off dirt and dirty water.

[0066] Furthermore, the wiper portion 416 of the second extrusion frame 412 and the first extrusion frame 411 may be provided with a plurality of scraping strips or scraping blades, so that a plurality of scraping strips or scraping blades act simultaneously in a single dehydration stroke, thereby fully ensuring the dehydration effect of the wiping surface.

[0067] Optionally, the scraping strip or blade included in the wiper portion 416 is an elastomer or a combination of an elastomer and a non-elastic body, wherein the elastomer portion ensures a close fit between the wiper portion 416 and the wiping surface of the mop head 200, thereby improving the squeeze scraping effect.

[0068] Further, such as Figure 4 As shown, one side of the wiper portion 416 has a guide slope, and the guide slope is arranged on a side close to the mop head 200 .

[0069] A guide slope is provided on one side of the scraper strip or scraper blade, and the guide slope is provided near the entry side of the mop head 200. When the mop head 400 moves from a high position to a low position, the mop head 200 enters the mop head 400, and plays a guiding role, so that the wiping surface can pass through the wiping opening 403. In addition, the first extrusion frame 411 and the second extrusion frame 412 gradually press the wiping surface, thereby improving the floating flexibility of the wiping opening 403.

[0070] Further, such as Figure 2 As shown, the dehydration device further includes scraping teeth 415 disposed on the crossbeam to clean the hair of the mop head 200 entering the mop opening 403 .

[0071] Optionally, the scraper teeth 415 are arranged on the opposite side of the extrusion member 402 away from the wiping portion 416. The scraper teeth 415 and the crossbeam are integrally formed, which has the technical effect of simple manufacturing and high structural strength. When the mop head enters the stroking opening 403, the scraper teeth 415 first contact the wiping surface of the mop head 200 and scrape off the hair and other filaments attached to the wiping surface. The scraper teeth 415 can be triangular, trapezoidal, rectangular or other teeth of any shape.

[0072] Furthermore, Figure 4 , Figure 5 , Figure 8 As shown, the extrusion 402 includes:

[0073] The squeezing roller 414 has two ends rotatably disposed on the opposite sides of the squeezing frame 401 , and the squeezing roller 414 rolls to squeeze and dehydrate the mop head 200 passing through the stroking opening 403 .

[0074] Optionally, an axial hole is provided on each of the fixing parts at both ends of the squeezing frame, and the axial holes on the two fixing parts are arranged opposite to each other. A shaft column corresponding to the shape and size of the shaft hole is provided at both ends of the squeezing roller, and the transitional cooperation between the shaft column and the shaft hole enables the squeezing roller to achieve relatively smooth rolling under the constraint of the shaft hole. The squeezing and dehydrating action is more labor-saving, and the user experience is good.

[0075] Further, such as Figure 4 , Figure 5 As shown, the squeezing roller 414 is provided with a water-absorbing material.

[0076] Specifically, the water-absorbing material is used to absorb part of the leaked liquid when the mop head 200 and the wiping surface leave the stroking head 400, ensuring that the surface of the mop head is relatively clean after squeezing and dehydration, and avoiding additional pollution caused by dripping of sewage. At the same time, the water-absorbing material is a flexible material that can adapt to the height changes or protrusions on the wiping surface, thereby improving the tightness of the combination of the squeezing roller 414 and the wiping surface.

[0077] Optionally, the water-absorbing material is tightly matched with the squeezing roller 414, and the two are separable, so as to facilitate replacement and cleaning of the water-absorbing material and increase the service life of a dehydration device of the present application.

[0078] Further, such as Figure 2 As shown, the dehydration device further includes a connecting frame 700, which is disposed between the water squeezing frame 401 and the extrusion frame and is detachably connected to the extrusion frame.

[0079] Optionally, the connecting frame 700 is arranged between the water squeezing frame 401 and the extrusion frame, and the connecting frame 700 is detachably connected to the water squeezing frame 401. Exemplarily, the connection methods include bolt connection, snap connection, ultrasonic welding and other connection methods. The setting of the connecting frame 700, on the one hand, improves the structural strength of the stroking head 400 and a dehydration device of the present application. On the other hand, it is also convenient for the production and processing of the water squeezing frame 401 and the connecting frame 700. In addition, compared with the technical solution of directly increasing the strength of the water squeezing frame 401 by increasing the material thickness, it has the technical effect of saving raw materials and reducing production costs.

[0080] Further, such as Figure 2 , Figure 5 As shown, the water squeezing rack 401 also includes:

[0081] A plurality of rollers 502 are provided on a side of the groove 403 opposite to the cross beam.

[0082] Optionally, multiple rollers 502 are symmetrically arranged on both sides of the connecting frame 700 of the squeezing frame 401, so that the back of the mop head 200 forms rolling friction with the squeezing frame 401 when passing through the stroking opening 403, and ensures that the mop head 200 is relatively parallel to the squeezing frame 401 during the movement, which has the technical effect of reducing the friction of the squeezing and dehydrating process and saving effort.

[0083] Optionally, the roller 502 has an integrally formed roller shaft column, and the connecting frame 700 is provided with a plurality of reinforcing walls on one side close to the cross beam, and a plurality of shaft column installation positions are reserved on the reinforcing walls, and the roller 502 is connected by snapping, so that the roller shaft column and the installation position on the reinforcing wall are clearance-matched to ensure that the roller shaft column can roll smoothly. The installation positions of the plurality of rollers 502 are located on the same installation plane, and the installation plane is parallel to the motion plane of the mop head.

[0084] Optionally, a trumpet-shaped opening is provided at the shaft column installation position reserved on the reinforcing wall, and the roller 502 is inserted into the shaft column installation position along the trumpet-shaped opening to facilitate the coordinated installation of the roller 502 .

[0085] Embodiment 2

[0086] like Fig. 9 As shown, a mop provided by the present application includes: a mop rod 100, a mop head 200, a mop sleeve 300, a mop head 400 and the dehydration device described in the first embodiment;

[0087] Among them, the mop head 200 is movably connected to the mop rod 100; the stroke sleeve 300 is arranged at one end of the mop rod 100 close to the mop head 200, and can generate relative movement along the mop rod 100; the stroke head 400 is connected to one end of the stroke sleeve 300 close to the mop head 200; the dehydration device is arranged at one end of the stroke sleeve 300 close to the mop head, and is connected to the stroke head 400 through the water squeezing rack 401. When the mop head 200 penetrates into the dehydration device and generates relative movement with the mop rod 100, the dehydration device squeezes and dehydrates the mop head 200.

[0088] Optionally, the mop head 200 is movably connected to the mop rod 100, and a second notch 202 is provided on the back of the mop head 200, and the second notch 202 appears in pairs.

The first notch 101 and the second notch 202 are connected through the connecting block 201. The first notch 101 and the connecting block 201 are rotatably matched to realize the rotation of the mop head 200 relative to the mop rod 100 in the first axial direction, and the second notch 202 and the connecting block 201 are rotatably matched to realize the rotation of the mop head 200 relative to the mop rod 100 in the second axial direction. The above two axial rotations ensure that the mop head 200 can freely realize the conversion from the extrusion dehydration state to the wiping working state.

[0089] Optionally, the mop head 200 and the mop rod 100 are movably connected to each other and have a positioning function, which is used to maintain the relative parallel state of the mop head 200 and the stroking head 400. Specifically, a slot is provided on the first notch 101, and the shape of the slot corresponds to the shape of the second notch 202, which is used to accommodate the second notch 202, ensuring fixation in the second axial direction. One or more groups of protrusions and grooves or pits are provided on the first notch 101 and the connecting block 201. When the mop head 200 and the stroking head 400 are in a relatively parallel state, the protrusions cooperate with the grooves or pits to achieve stability in the first axial direction, thereby ensuring the relative parallel state of the mop head 200 and the stroking head 400, making it easier for the mop head to enter the stroking mouth 403 during the squeezing and dehydration process, thereby improving the user experience.

[0090] Embodiment 3

[0091] like Fig.10 As shown, a mop bucket provided in the present application includes: a mop bucket body 600 and the dehydration device described in the first embodiment.

[0092] The dehydrating device including any of the above structures is arranged on the mop bucket body 600 and is connected to the mop bucket body 600 via the water squeezing rack 401 . The dehydrating device can dehydrate the mop.

[0093] Optionally, the dehydrating device is connected to the mop bucket body 600 via the water squeezing rack 401 , and the connection methods include one-piece molding, ultrasonic welding, screw connection, snap connection and other connection methods, and the rotation direction of the dehydrating device is toward the inner bottom of the mop bucket body 600 .

[0094] In summary, by movably connecting the dehydrating part and the connecting part, when the extruding part dehydrates the mop head, the extruding part, driven by the mop head, rotates in a direction close to the mop head, so that the distance between the extruding part and the mop head gradually decreases, thereby increasing the extrusion force. This solves the technical problem in the prior art that the dehydrating part and the connecting part are fixedly connected, resulting in a fixed relative distance between the dehydrating part and the mop, which results in a relatively small extrusion force of the dehydrating part on the mop while ensuring that the mop can be dehydrated smoothly, further resulting in poor dehydration effect of the mop, and achieves the technical effect of improving the dehydration effect.

[0095] Although the present application has been described in conjunction with specific features and embodiments thereof, it is obvious that various modifications and combinations may be made thereto without departing from the spirit and scope of the present application. Accordingly, this specification and the accompanying drawings are merely exemplary illustrations of the present application as defined therein, and are deemed to have covered any and all modifications, variations, combinations or equivalents within the scope of the present application.
