Description

Technical Field

[0001] The invention relates to a water squeezing device, in particular to a water squeezing device for a foam cotton head mop. Background Art

[0002] The cleaning of conventional foam mops is usually not limited by the shape or structure of the mop bucket. For example, the foam mop itself is folded or squeezed to clean the cotton wool, or a squeezing roller is set on the mop to squeeze and clean the foam mop through the relative movement between the squeezing roller and the foam mop. However, it is inevitable that the structure of the foam mop is more complicated, the weight is increased, and it is easy to cause component failure and labor during use. The mop bucket used for cleaning and squeezing the foam mop in the prior art still has the following defects.

[0003] For example, the invention application with publication number CN105769083A and titled “A Rubber Cotton Mop Cleaning Bucket” discloses a mop bucket for horizontally squeezing a rubber cotton mop, including a barrel body for cleaning a rubber cotton head and a base fixed on the barrel body, the base being provided with a water squeezing device and a driving device, the water squeezing device including a water squeezing fixed plate, a water squeezing movable plate, and a guide rail connecting rod, an expansion portion being provided on the upper portion of the base, a guide rail groove being provided on the expansion portion, the water squeezing fixed plate being fixed to the expansion portion through a fixed plate seat, the water squeezing movable plate being fixed to the guide rail connecting rod through a movable plate seat, the rubber cotton head being placed between the water squeezing fixed plate and the water squeezing movable plate during dehydration, the driving device drives the water squeezing movable plate to move toward the water squeezing fixed plate through the guide rail connecting rod to clamp the rubber cotton head to squeeze water. However, there are quite a lot of parts involved in the mop bucket of the above scheme. Once a part fails or is damaged, the cleaning work of the collodion mop cannot be completed. The environment inside the bucket is humid and the parts inside the bucket are often stressed. The more parts there are, the higher the probability of failure. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a water squeezing device for a foam cotton head mop which has a simple and compact structure, can squeeze water quickly, has a high squeezing rate and is easy to process.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: a water squeezing device for a foam head mop, comprising a shell and a squeezing frame arranged on the shell, the squeezing frame is provided with a water squeezing groove, characterized in that: the water squeezing groove has an upward opening and is vacantly arranged on the shell, at least part of the bottom surface and the peripheral surface of the water squeezing groove can cause a squeezing effect on the foam head of the foam head mop, and the water squeezing groove is also provided with an outlet for water outflow, after the foam head of the foam head mop is placed in the water squeezing groove, a downward squeezing force is applied to the foam head mop, so that the foam head is squeezed out of water by the water squeezing groove.

[0006] Preferably, the size of the water squeezing groove is the same as or larger than the size of the foam cotton head, and the bottom of the shell is closed or open. The size of the water squeezing groove matches the size of the foam cotton head, which helps the inner surface of the water squeezing groove to contact the surface of the foam cotton head, thereby improving the squeezing effect and making the water squeezing more complete.

[0007] Preferably, the water squeezing trough is positioned on the shell by a squeezing frame. The arrangement of the squeezing frame can provide more options for the position and form of the water squeezing trough, thereby expanding the applicable scenarios of the water squeezing device.

[0008] The shell is provided with a water storage cavity, the squeezing frame is located at the bottom of the water storage cavity and rises from bottom to top, and the squeezing water tank is located at the upper part of the squeezing frame; the squeezing water tank is located at the same level as the opening of the water storage cavity, or is lower than the opening of the water storage cavity. The squeezing frame rises from the bottom of the water storage cavity, and the squeezing water tank is installed at the upper part of the squeezing frame, so when squeezing water, dirty water can be prevented from splashing out to a certain extent. In particular, when the squeezing water tank is located at a position lower than the opening of the water storage cavity, dirty water can be effectively prevented from splashing out; if the squeezing water tank is located at the center of the water storage cavity, the splash-proof effect can be further improved.

[0009] The housing is provided with a water storage cavity, the squeezing frame is located at the inner wall of the water storage cavity and bulges inward, the squeezing groove is located at the upper part of the squeezing frame; the position of the squeezing groove is level with the opening position of the water storage cavity, or lower than the opening position of the water storage cavity. Similarly, the splash-proof effect can be effectively improved.

[0010] Preferably, the water trough and the extrusion frame are integrally formed or separately formed. If the water trough and the extrusion frame are integrally formed, the assembly cost can be reduced in the existing process, and the production cost and transportation cost can also be reduced. If they are separately formed, when one of the components is damaged, it is convenient to replace it, reducing the replacement cost.

[0011] Similarly, the extrusion frame and the shell are integrally formed or separately formed. When the extrusion frame and the shell are integrally formed, the extrusion trough and the extrusion frame can also be integrally formed or separately formed, and the same is true when the extrusion frame and the shell are separately formed. In general, when the extrusion frame and the shell, the extrusion trough and the extrusion frame are integrally formed, only one set of molds is needed, and the shell produced by one set of molds not only saves assembly, but also reduces production costs.

[0012] Preferably, the outlet is a water squeezing hole, and the water squeezing hole is provided on at least part of the peripheral surface and bottom surface of the water squeezing groove. Among them, "the water squeezing hole is provided on at least part of the surface", due to the existence of the word "at least", the position of the water squeezing hole mainly refers to the following three situations: 1. The water squeezing hole is only located on the part where the peripheral surface is located; 2. The water squeezing hole is only located on the part where the bottom surface is located; 3. The water squeezing hole is located on both the peripheral surface and the bottom surface. Here, the shape of the water squeezing hole can be adjusted as needed, such as round, square, long strip, etc., and the size of the hole can also be large or small.

[0013] Preferably, the squeezing holes are evenly distributed or unevenly distributed, and different distribution modes are suitable for different types of foam cotton heads and can bring corresponding drainage effects.

[0014] In order to achieve a better extrusion effect, the outlet is a slot, the slot is arranged on the peripheral surface of the water squeezing groove, and a convex point protruding upward is arranged on the bottom surface of the water squeezing groove.

[0015] In order to make the squeezing groove have a better squeezing effect, the cross section of the squeezing groove gradually decreases from top to bottom. When the foam head faces downward and enters the squeezing groove from top to bottom, it is squeezed by the inner surface of the squeezing groove. During the downward movement, the squeezing deformation is larger and larger, so that the squeezing effect is greatly improved and the squeezing is more complete.

[0016] Preferably, the bottom surface of the water squeezing trough is arc-shaped and protrudes upward.

[0017] Preferably, when there are water squeezing holes on the bottom surface, the size of the water squeezing holes is 0.025%-25% of the total area of ​​the bottom surface, and the total area of ​​the water squeezing holes accounts for 20%-60% of the total area of ​​the bottom surface.

[0018] Preferably, the water squeezing tank is further provided with an auxiliary water squeezing device for squeezing the foam cotton head from above or from the side.

[0019] As an optional embodiment of the present invention, the auxiliary water squeezing device squeezes the foam cotton head downward from the top, and the auxiliary water squeezing device includes a pressing plate that flips and squeezes from the top to the bottom, and a driving mechanism that drives the pressing plate to move.

[0020] Preferably, a rotation axis is provided on one side edge of the pressure plate, and the pressure plate is rotationally connected to the housing through the rotation axis. The driving mechanism includes a connecting rod, a steering connecting rod, and a pedal connected to the lower end of the connecting rod. One end of the steering connecting rod is hinged to the upper end of the connecting rod, and the other end of the steering connecting rod is hinged to the lower surface of the pressure plate. When the pedal is pressed down, the connecting rod moves downward and drives the pressure plate to rotate and press downward around the rotation axis. The steering connecting rod can make the linkage relationship with the pressure plate smoother when the connecting rod moves downward, and at the same time ensure that the connecting rod can move in a vertical state when it moves downward without causing spatial displacement.

[0021] Preferably, a rotation shaft is provided on one side edge of the pressure plate, and the pressure plate is rotationally connected to the housing through the rotation shaft, and the driving mechanism includes a connecting rod, a pedal connected to the lower end of the connecting rod, and the upper end of the connecting rod is hingedly matched with the lower surface of the pressure plate. When the pedal is pressed down, the connecting rod moves downward and drives the pressure plate to rotate and press downward around the rotation shaft. Compared with the previous solution, the steering connecting rod component is reduced, thereby reducing the cost.

[0022] The shell is provided with an elastic member that enables the pressure plate to have an upward flipping tendency. The elastic member here can be a spring, a torsion spring, a spring sheet, or an elastic rubber pad, etc., and regarding the installation of the elastic member, a matching position can be adopted according to the different properties and structures of the elastic member, so that the pressure plate has an upward flipping tendency. Of course, since the pressure plate is connected to the connecting rod and the steering connecting rod, in order to maintain the pressure plate with an upward flipping tendency, the elastic member can act on the connecting rod or the steering connecting rod in addition to directly acting on the pressure plate, so that the connecting rod or the steering connecting rod has a movement tendency in a certain direction, and under this tendency, the pressure plate has an upward flipping tendency. The above relationship between the elastic member and the movement tendency of the pressure plate is a technology that can be easily thought of by those skilled in the art, and will not be elaborated here.

[0023] As another optional embodiment of the auxiliary water squeezing device of the present invention, the auxiliary water squeezing device squeezes the foam head from the side, and the water squeezing groove includes a bottom surface and two oppositely arranged side surfaces, wherein the bottom surface and the side surfaces are separately arranged and rotate with each other; the auxiliary water squeezing device includes a squeezing block, one end of which is hinged to the squeezing frame or the shell through a first hinge shaft, and the first hinge shaft is arranged along the extension direction of the side surface, and the other end of the squeezing block is hinged to the side surface through a second hinge shaft, when the bottom surface is pressed to move downward, the bottom surface rotates around the second hinge shaft with the side surface, and the side surface rotates around the first hinge shaft with the squeezing block during the movement, so that the squeezing block squeezes the side surface of the foam head during the rotation, wherein the surface of the squeezing block that squeezes the side surface of the foam head is provided with an squeezing protrusion. The bottom surface, side surfaces and extrusion blocks are connected in sequence and hinged to each other through hinge shafts. When the bottom surface of the foam head is placed downward in the water squeezing trough and the foam head is squeezed downward, the bottom surface of the water squeezing trough is pressed downward, and the side surfaces and the extrusion blocks are driven to rotate around their respective hinge shafts. During the rotation of the extrusion block, the side surfaces of the foam head are squeezed by the extrusion protrusions arranged on the surface, thereby increasing the deformation of the foam head under pressure to improve the water squeezing effect.

[0024] The auxiliary squeezing device also includes a reset member that makes the bottom surface have an upward movement tendency. When the bottom surface has an upward movement tendency, the squeezing protrusion on the squeezing block turns outward around the first hinge axis, and the squeezing protrusion at this time does not invade the squeezing groove, so it will not squeeze the foam cotton head that just enters the squeezing groove; as the bottom surface moves downward, it drives the side surface and the squeezing block to move downward and turn around the hinge axis, and the squeezing protrusion of the squeezing block after turning over invades the space where the squeezing groove is located, thereby squeezing the foam cotton head. Therefore, the reset member can act on the bottom surface, the side surface, the squeezing block and other components, and the specific form can be selected according to the form of the reset member.

[0025] Preferably, an elastic member is provided between the connecting rod and the housing to keep the connecting rod always pointing upward.

[0026] As another optional embodiment of the present invention, the auxiliary water squeezing device squeezes the foam head from the side, and the bottom surface and the surrounding surface of the water squeezing trough are separately arranged. The auxiliary water squeezing device includes a squeezing block, and the end of the squeezing block is hinged to the end surface of the water squeezing trough and can rotate around a hinge axis extending along the side of the water squeezing trough. The end of the squeezing block is also hinged to the bottom surface of the water squeezing trough. By squeezing the mop head downward, the bottom surface of the water squeezing trough is driven to move downward, and at the same time, the squeezing block is driven to rotate around the hinge axis to flip and extrude the foam head.

[0027] Preferably, the end of the extrusion block is provided with a first hinge and a second hinge, the first hinge is inserted into the hinge hole on the end surface of the water extrusion trough, and the first hinge is the hinge around which the extrusion block rotates and flips, the second hinge is hinged with one end of a hinge plate, and the other end of the hinge plate is hinged to the end of the bottom surface.

[0028] Preferably, a water storage chamber is provided on the housing, and a cleaning device is provided in the water storage chamber, and the cleaning device includes a scraper installed on the side wall of the water storage chamber or / and the bottom of the water storage chamber, and the scraper surface is provided with protrusions and / or bristles for scraping the surface of the foam cotton head. When the foam cotton head is cleaned in the water storage chamber, the foam cotton head is brushed at the cleaning device to remove dirt adhered to the surface of the foam cotton head, thereby improving the cleaning efficiency.

[0029] Preferably, a water storage chamber is provided on the shell, and a cleaning device is provided in the water storage chamber. The cleaning device is a cleaning tank that matches the size of the foam cotton head. The inner surface of the cleaning tank is provided with protrusions and / or bristles for scraping the surface of the foam cotton head. When the foam cotton head enters and exits the cleaning tank, the surface of the foam cotton head is scraped and brushed by the protrusions and / or bristles in the cleaning tank. The size of the cleaning tank matches the volume of the foam cotton head. By inserting the foam cotton head into the cleaning tank, the protrusions or bristles on the surface of the cleaning tank will scrape and brush the surface of the foam cotton head, thereby removing dirt adhered to the surface of the foam cotton head, thereby improving the cleaning efficiency.

[0030] Preferably, the protrusions are convex strips and / or convex dots. The convex strips or convex dots can effectively scrape the surface of the foam head, and the cleaning efficiency is better than other structures.

[0031] Compared with the prior art, the advantage of the present invention is that the squeezing device of the foam head mop is not only simple in structure and easy to use, but also can squeeze water conveniently, and has a good squeezing effect, and is easy to process and use. Among them, "at least part of the bottom surface and the peripheral surface of the squeezing trough can cause a squeezing effect on the foam head of the foam head mop". Due to the existence of the word "at least", the surface of the squeezing trough that produces a squeezing effect on the foam head here mainly refers to the following three situations: 1. Only the bottom surface squeezes the foam head; 2. Only the peripheral surface squeezes the foam head; 3. The bottom surface and the peripheral surface squeeze the foam head at the same time. The peripheral surface is a general term for the circumferential side surface surrounding the squeezing trough in the traditional sense, that is, the peripheral surface is generally surrounded by side surfaces in four directions, and the side surfaces here are at least two oppositely arranged sides.

[0032] The squeezing frame is made of elastic material; the cross-sectional dimension of the lower part of the squeezing groove is equal to or smaller than the cross-sectional dimension of the foam cotton head. The elastic material can be elastic plastic or metal, and the specific composition or component of the plastic or metal can be selected according to conventional practices. When the foam cotton head is pressed down, the squeezing frame is deformed by the downward pressure, and the deformed inner wall of the squeezing groove will form an extrusion force on the surface of the foam cotton head, thereby improving the squeezing effect of the foam cotton head.

[0048] The present invention is further described in detail below with reference to the accompanying drawings.

[0049] Embodiment 1: Figure 1-5 As shown, the water squeezing device of the foam head mop includes a shell 1, and the shell 1 forms a space for accommodating water. The shell 1 can be a closed container or just a bracket, that is, the space for accommodating water can be a closed space or a space connected to the outside world. The water squeezed out from the mop can be accommodated in the space or directly flow out to the outside world.

[0050] The housing 1 is provided with a squeezing frame 2, which is located above the housing 1 and is used to fix the squeezing trough 3 and position the squeezing trough 3 in a vacant position above the housing 1. The squeezing trough 3 is vacant and has an upward opening. The side surface 33, end surface and bottom surface 32 of the squeezing trough 3 are provided with squeezing holes 31 on at least part of the surface. Figure 1-5 As shown, in this embodiment, a plurality of squeezing holes 31 are evenly spaced on the bottom surface of the squeezing trough 3, and a portion of the side surface 33 is provided with squeezing holes 31. As shown in the figure, a portion of the side surface 33 close to the bottom surface 32 is evenly spaced with a plurality of squeezing holes 31.

[0051] It should be pointed out that the squeezing frame 2 and the water squeezing trough 3 in this embodiment are integrally formed, the shell 1 is a closed space, the shell 1 is provided with an upward opening, the squeezing frame 2 is provided at the top of the shell 1, and plays the role of closing the opening of the shell 1, the water squeezing trough 3 is connected to the space inside the shell 1 through the water squeezing hole 31 provided thereon, and the water of the mop squeezed out of the water squeezing trough flows into the shell 1 through the water squeezing hole 31.

[0052] The size of the squeezing groove 3 matches the size of the foam head of the foam mop. In order to achieve a better squeezing effect, more implementation schemes can be extended: the squeezing groove 3 can be slightly smaller than the foam head, so that the foam head can be inserted and squeezed by the circumference; it can also be consistent with the size of the foam head; or slightly larger than the size of the foam head; or the size of the squeezing groove is larger than the size of the foam head, so that the foam head is squeezed only by the bottom surface. For example, the size of the transverse cross-section of the squeezing groove 3 gradually decreases, such as Figure 3 As shown, the side surfaces 33 of the water squeezing groove 3 gradually approach from top to bottom, and the end surfaces of the water squeezing groove 3 in this embodiment are parallel to each other. And those skilled in the art can understand that the end surfaces of the water squeezing groove 3 can also gradually approach from top to bottom, so that the cross section of the opening of the water squeezing groove 3 can be slightly larger than the foam cotton head, and the cross section at the bottom surface can be slightly smaller than the foam cotton head, thereby being able to produce a squeezing effect on the foam cotton head.

[0053] Furthermore, in order to achieve a better squeezing effect, the bottom surface 32 may be a convex surface that is convex upward, for example, the cross section of the bottom surface 32 in the width direction is arc-shaped. It should be noted that the bottom surface 32 may be arc-shaped in cross section along the width direction, may be arc-shaped in cross section along the length direction, or may be an arc-shaped convex surface in both directions. With such a configuration, the foam head can be squeezed out of water more easily and better through the upward protrusion of the bottom surface 32. Furthermore, those skilled in the art can also understand that as long as at least part of the bottom surface or peripheral surface of the squeezing trough can exert a squeezing effect on the foam head of the foam head mop and thereby cause it to discharge water, it can be sufficient. Of course, there is also the following implementation scheme: the cross section of the squeezing trough 3 gradually decreases from top to bottom, and combined with the arc-shaped structure of the bottom surface 32, the squeezing effect can be better exerted.

[0054] like Figure 1-5As shown, the foam head mop includes a mop rod 61 and a foam head 62. The foam head 62 can be folded relative to the mop rod 61 to a position parallel to the mop rod 61, or unfolded to a position perpendicular to the mop rod 61. When the mop rod 61 and the foam head 62 are perpendicular to each other, the foam head 62 is placed in the water squeezing tank 3, and the foam head 62 is gradually squeezed downward by applying downward pressure to the mop rod 61. The water squeezed out of the foam head 62 flows into the space below through the squeezing hole 31, so that the foam head 62 is squeezed dry. Such a structure is not only simple and compact, but also easy to process, and has a good squeezing effect.

[0055] In order to achieve a better squeezing effect, the squeezing holes of the bottom surface 32 have a size of 0.025%-25% of the total area of ​​the bottom surface, and the total area of ​​the squeezing holes accounts for 20%-60% of the total area of ​​the bottom surface. The downward force applied from the mop rod will be transferred to the foam head 62, and finally applied to the squeezing trough. If the area of ​​the squeezing holes on the squeezing trough is too small, the drainage effect will be poor. If the area of ​​the squeezing holes on the squeezing trough is too large, the foam head 62 will be squeezed out of the squeezing holes, and then the squeezing amount of the foam head will be reduced. Therefore, the area of ​​the squeezing holes on the squeezing trough should not be too large or too small, and the total area of ​​the squeezing holes should not be too large or too small to account for the area of ​​the bottom surface, which will not only affect the squeezing effect, but also easily reduce the strength of the bottom surface.

[0056] In this embodiment, an auxiliary water squeezing device is also included, which includes a pressure plate 41 and a driving mechanism for driving the pressure plate 41 to move. One side edge of the pressure plate 41 is rotatably connected to one side of the water squeezing groove 3 through a rotating shaft 44. For example, the rotating shaft 44 is arranged on one side edge of the pressure plate 41, and the ends protruding from the pressure plate 41 at both ends are inserted into corresponding plug-in holes located in the shell 1, so that the pressure plate 41 can rotate around the rotating shaft 44. The pressing plate 41 is used to press down the foam head 62 placed in the squeezing tank 2; a connecting shaft 42 is fixed on the lower surface of the pressing plate 41, and the connecting shaft 42 extends in the same direction as the rotating shaft 44. The driving mechanism includes a connecting rod 51, a pedal 52 fixedly connected to one end, i.e., the bottom end, of the connecting rod 51, and a steering connecting rod 53, one end of the steering connecting rod 53 is hinged to the other end, i.e., the upper end of the connecting rod 51, and the other end of the steering connecting rod 53 is hinged to the connecting shaft 42, i.e., the other end of the steering connecting rod 53 is hinged to the lower surface of the pressing plate 41 and the hinged position is spaced from the rotating shaft 44. One side of the squeezing tank 3 has a through hole (not shown in the figure) for allowing the steering connecting rod 53 to pass through. When the pedal 52 is pressed down, the connecting rod 51 moves downward, and the connecting shaft 42 drives the pressing plate 41 to press downward. At this time, the pressing plate 41 cannot move downward with the steering connecting rod 5, but can only rotate around the rotating shaft 44 to press downward the foam head 62 in the squeezing tank 3. When the pedal 52 is lifted, the connecting rod 1 is reset upward, and the connecting shaft 42 drives the pressing plate 41 to release the foam head 62 upward. Repeating this action can complete the squeezing work. With the help of the downward force of the hand-held mop rod 61, the squeezing can be completed faster. Therefore, the connecting rod 1 needs to be provided with a reset mechanism to keep it in the upward position at all times.

[0057] Preferably, a hollow groove 11 matching the shape of the connecting rod 51 is provided in the housing 1, the hollow groove extends to one side of the water squeezing trough 3, and the steering connecting rod and the pressure plate are exposed outside the hollow groove 11. In this embodiment, the connecting rod 51 is a pair of symmetrically arranged, and correspondingly, the hollow groove 11 is also a pair of symmetrically arranged. The hollow groove 11 allows the connecting rod 51 to move up and down inside it, which not only protects the connecting rod 51, but also serves as a guide for the movement of the connecting rod 51, so that the connecting rod 51 can move up and down stably inside the hollow groove 11. The hollow groove 11 is integrally formed with the housing 1 for easy installation.

[0058] In this embodiment, the reset mechanism includes a reset spring 71, and the connecting rod 51 is fixedly connected to a transversely extending crossbeam 54. A blind hole (not shown in the figure) is provided on the lower surface of the crossbeam 54 to allow the first end of the reset spring 71 to be inserted. A positioning column 12 is provided on the housing 1 below the blind hole. The second end of the reset spring 71 is sleeved on the positioning column 12. The reset spring 71 makes the connecting rod 51 always have an upward trend. When the pedal 52 is stepped on, the reset spring 71 is compressed. When the pedal 52 is released, the reset spring 71 is reset, and the pedal 52 is automatically lifted upward. And those skilled in the art can understand that the reset spring and the crossbeam can also be elastic members of other structures, as long as the connecting rod 51 has a tendency to always be upward. The elastic member here can also be a torsion spring, a spring sheet, or an elastic rubber pad, etc., and regarding the installation of the elastic member, according to the different properties and structures of the elastic member, a matching position can be adopted to make the pressure plate have an upward flipping tendency. Of course, since the pressing plate is connected to the connecting rod and the steering connecting rod, in order to keep the pressing plate having an upward turning tendency, the elastic member can act on the connecting rod or the steering connecting rod in addition to directly acting on the pressing plate, so that the connecting rod or the steering connecting rod has a movement tendency in a certain direction, and under this tendency, the pressing plate has an upward turning tendency. The above relationship between the elastic member and the movement tendency of the pressing plate is a technology that can be easily thought of by those skilled in the art, and will not be elaborated here one by one.

[0059] In order to make the pressing plate 41 cover the foam head 62 as effectively as possible and increase the coverage area of ​​the downward pressure, the size of the pressing plate 41 is as close to the opening area of ​​the squeezing tank 2 as possible, but at the same time, in order to avoid the mop rod 61, a notch 43 is provided on the pressing plate 41. When the mop is placed in the squeezing tank 2, the pressing plate 41 is folded to press the foam head 62, and the mop rod 61 passes through the notch 43, and the mop rod 62 does not block the reciprocating movement of the pressing plate 41. The auxiliary squeezing device can apply a downward force to the foam head from above, so that the foam head can be squeezed out more easily.

[0060] Embodiment 2: Figure 6-8As shown, the squeezing device of the foam head mop of the second embodiment of the present invention is shown. In this embodiment, the squeezing tank 3' and the squeezing frame 2' are integrally formed, the shell 1 is a closed structure with an opening at the top, the squeezing frame 2' extends upward from the inner bottom of the shell 1 to the top of the shell 1, the squeezing tank 3' is located at the opening of the shell 1 at the top of the squeezing frame 2', and the squeezing tank 3' is located on one side of the opening at the top of the shell 1, and the other side of the opening is open. Slots 31' are provided on several side surfaces and end surfaces of the squeezing tank 3', and the slots 31' are evenly spaced and extend from the edge of the bottom surface 32' to the edge of the side surface 33'. There are no openings on the bottom surface 32', but there are convex points 321 protruding upward. The convex points 321 are arranged in a matrix on the bottom surface 32', and the intervals of the convex points 321 on the bottom surface 32' can be the same or different, or the convex points 321 can be arranged in a disordered manner on the bottom surface 32. The convex point 321 can make it easier to squeeze the foam head 62. The housing 1 below the squeezing frame 2' is open, that is, the bottom of the squeezing frame 2' is directly connected to the outside, and the water squeezed out of the mop also flows directly from the squeezing frame 2' to the outside without staying in the housing 1.

[0061] Embodiment 3: Figure 9-12 FIG. 1 is a third embodiment of a water squeezing device for a foam mop according to the present invention. In this embodiment, the squeezing frame is omitted, and the housing 1 is a closed structure with an opening at the top, and a squeezing trough 3" is hung on the opening. The top of the squeezing trough 3" is provided with a flange surface protruding outward and resting on the edge of the opening of the housing 1. The bottom surface 32" of the squeezing trough 3" is separated from the peripheral surface, and a plurality of openings 31" are provided on the bottom surface 32". The openings 31" can be regularly arranged in a matrix shape, or can be irregularly arranged, that is, arranged in a disordered manner, or can be evenly spaced, or irregularly arranged. Uniformly arranged. Hinge holes 35' are provided on the end faces 34'' at both ends of the water squeezing trough 3'', and a first hinge shaft 361'' is inserted into the hinge hole 35''. Extrusion blocks 37'' are provided on both sides of the water squeezing trough 3'' along the length direction of its side surface 33''. The first hinge shaft 361'' is fixedly connected to the lower end of the extrusion block 37'', so that the extrusion block 37'' can be turned up and down around the first hinge shaft 361'', that is, it can be rotated up and down around an axis in the same direction as the extension direction of the side surface 33'', that is, the first hinge shaft 361'' extends along the side surface 33'' of the water squeezing trough. And the upper end of the extrusion block 37'' is hinged to one end of the hinge plate 38''. Preferably, a second hinge shaft 362'' is provided above the end of the extrusion block 37'', and the second hinge shaft 362'' is inserted into one end of the hinge plate 38'', and the other end of the hinge plate 38'' is hinged to the end of the bottom surface 32''.

[0062] Furthermore, an elastic member is provided below the squeezing block or the bottom surface so that the two have an upward tendency all the time. When the foam head 62 of the mop is placed in the squeezing groove 3", and the mop rod 61 is used to squeeze the foam head 62 downward, the force exerted on the foam head can drive the bottom surface 32" to move downward, and the bottom surface 32" drives the hinged piece 38" and the squeezing block 37" to rotate around the first hinge shaft 361", so that the squeezing block 37" rotates from top to bottom and squeezes the foam head 62 from the side. The squeezing block 37" can be arranged on both sides of the squeezing groove 3", or at the end of the squeezing groove 3", that is, it can be arranged on a part of the circumference of the squeezing groove. The squeezing block can squeeze the foam head 62 from the side at the same time during the downward squeezing of the mop, so as to better squeeze the foam head 62. The function of the reset member is to make the bottom surface have an upward movement tendency. When the bottom surface has an upward movement tendency, the extrusion protrusion on the extrusion block turns outward around the first hinge axis. At this time, the extrusion protrusion does not invade the water squeezing groove, so it will not squeeze the foam cotton head that just enters the water squeezing groove; as the bottom surface moves downward, it drives the side surface and the extrusion block to move downward and turn around the hinge axis, and the extrusion protrusion of the extrusion block after turning over invades the space where the water squeezing groove is located, thereby squeezing the foam cotton head. Therefore, the reset member can act on the bottom surface, side surface, extrusion block and other components, and the specific form can be selected according to the form of the reset member.

[0063] The squeezing block in this embodiment is actually an auxiliary squeezing device, which is used to squeeze the foam cotton head of the mop from the side. Of course, those skilled in the art will appreciate that auxiliary squeezing devices with other structures or auxiliary squeezing devices that squeeze the foam cotton head from other directions may also be provided. The auxiliary squeezing device causes the side of the squeezing trough to squeeze the foam cotton head, thereby being able to better squeeze out the foam cotton head of the mop.

[0064] Therefore, it should be pointed out that the above are only a few different implementations. As long as the mop is placed in the squeezing tank and squeezed from top to bottom, the mop is squeezed by the bottom surface and part of the peripheral surface of the squeezing tank, such as the blocking squeezing of the horizontal bottom surface, and the squeezed water flows out of the squeezing tank. The outlet for the water to flow out can be an opening provided on the bottom surface or part of the peripheral surface, or a groove provided, or other forms of outlets for water to flow out. Moreover, the squeezing tank needs to be set at a certain height and vacant. The squeezed water can be kept in the shell or directly flow out to the outside.

[0065] The water squeezing device of the foam cotton head mop has not only a simple structure and is easy to use, but also can squeeze water conveniently, has a good water squeezing effect, and is easy to process and use.

[0066] It is particularly pointed out that the combination of the housing 1, the squeezing frame 2, and the squeezing tank 3 can be combined in other forms in addition to the solutions disclosed in the first, second, and third embodiments. Figures 6 to 8 As shown, a water-holding cavity is provided on the shell 1, the squeezing frame 2 is located at the bottom of the water-holding cavity and rises from bottom to top, and the squeezing trough 3 is located on the upper part of the squeezing frame 2; the position of the squeezing trough 3 is level with the opening position of the water-holding cavity, or lower than the opening position of the water-holding cavity. The squeezing frame 2 rises from the bottom of the water-holding cavity, and the squeezing trough 3 is installed on the upper part of the squeezing frame 2, so that when squeezing water, dirty water can be prevented from splashing out to a certain extent. In particular, when the squeezing trough 3 is located below the opening position of the water-holding cavity, dirty water can be effectively prevented from splashing out; if the squeezing trough 3 is located in the central position of the water-holding cavity, the splash-proof effect can be further improved. The squeezing trough 3 and the squeezing frame 2 are integrally formed, which can reduce the assembly cost in the existing process, and can also reduce the production cost and transportation cost. If the squeezing trough 3 and the squeezing frame 2 are separately formed, when one of the components is damaged, it is convenient to replace, thereby reducing the replacement cost.

[0067] Combination scheme 2: The squeezing frame 2 can also be located on the inner wall of the water storage cavity and bulge inward, and the squeezing groove 3 is located on the upper part of the squeezing frame 2; the position of the squeezing groove 3 is level with the opening position of the water storage cavity, or lower than the opening position of the water storage cavity. Similarly, the splash-proof effect can be effectively improved. The squeezing frame 2 and the housing 1 are integrally formed or separately formed, which is consistent with the above effect.

[0068] Combination scheme 1 and combination scheme 2 are improvements on the shell 1, the squeezing frame 2, and the squeezing trough 3. These two combination schemes can be combined with the schemes of embodiments 1 to 3 respectively to form new embodiments, and both fall within the protection scheme of this embodiment.

[0069] Embodiment 4: The main difference from Embodiment 1 is that a water storage chamber 17 is provided at the housing 1, and a cleaning device 7 is provided in the water storage chamber 17. The cleaning device 7 includes a scraper 71 installed on the side wall and the bottom of the water storage chamber 17, and the surface of the scraper 71 is provided with a protrusion 76 and a bristle 75 for scraping the surface of the foam head 62. The scraper 71 can be detachably installed at the bottom of the water storage chamber 17 by means of a buckle, a plug-in structure, etc. At the same time, the scraper 71 at the side wall of the water storage chamber 17 is provided with bristles 75, and the scraper 71 at the bottom of the chamber 17 is provided with a convex point. Here, the convex point can also be replaced by a convex strip. When the foam head 62 is cleaned in the water storage chamber 17, the foam head 62 is allowed to be hung and brushed at the cleaning device 7, so as to remove the dirt adhering to the surface of the foam head 61, thereby improving the cleaning efficiency.

[0070] Embodiment 5: The main difference from Embodiment 4 is that a water holding chamber 17 is provided on the housing 1, and a cleaning device 7 is provided in the water holding chamber 17. The cleaning device 7 is a cleaning tank 72 that matches the size of the foam head 62, and the inner surface of the cleaning tank 72 is provided with bristles 76 for scraping the surface of the foam head. When the foam head 62 enters and exits the cleaning tank 72, the surface of the foam head 62 is scraped and brushed by the bristles 76 in the cleaning tank 72. The size of the cleaning tank 72 matches the volume of the foam head 62. By inserting the foam head 62 into the cleaning tank 72, the protrusions or bristles 76 on the surface of the cleaning tank 72 will scrape and brush the surface of the foam head 62, thereby removing the dirt adhered to the surface of the foam head 62, thereby improving the cleaning efficiency. Here, the bristles 76 can also be replaced by convex points or convex strips.

[0071] In the above embodiments, the squeezing frame 2 is made of elastic plastic material, and the cross-sectional dimension of the lower portion of the squeezing tank 3 is smaller than the cross-sectional dimension of the foam head 62. Figure 3 As shown in the figure, the side surface 33 of the water squeezing trough 3 gradually shrinks and converges from top to bottom. The concept of "smaller than" is that the foam head 62 can still be inserted into the lower part of the water squeezing trough 3 after being compressed. Here, the cross-sectional size of the lower part of the water squeezing trough 3 can also be equal to the cross-sectional size of the foam head 62, both of which can improve the water squeezing effect of the foam head 62. In addition, the elastic plastic material and the elastic metal material can also be selected. The specific composition or component of the plastic or metal can be selected according to conventional habits. For the present technical solution, it is preferably applied to the extrusion frame 2 without the auxiliary extrusion device.
