Description

Technical Field

[0001] The utility model relates to the technical field of mop washing buckets, in particular to a water squeezing device and a mop washing bucket. Background Art

[0002] For the existing traditional water squeezing device on the mop washing bucket, usually, the user needs to twist and squeeze the mop forcefully to squeeze the water out of the leakage holes of the water squeezing device, which is very laborious. Summary of the Utility Model

[0003] The embodiment of the utility model provides a water squeezing device and a mop washing bucket to solve the above or other potential problems in the prior art.

[0004] According to one aspect of the utility model, a water squeezing device is provided, including:

[0005] A water squeezing tank, at the top of which there is a first inlet, and on the side wall and / or bottom of the water squeezing tank, there are also provided a plurality of leakage holes, and on the water squeezing tank, there is also provided an installation structure for installing on the mop washing bucket;

[0006] A pressing plate, which is slidably arranged in the water squeezing tank;

[0007] A push-pull assembly, which is arranged in the water squeezing tank and is connected with the pressing plate to drive the pressing plate to approach or move away from an inner side wall of the water squeezing tank.

[0008] The water squeezing device of the utility model controls the movement of the pressing plate through the push-pull assembly, and thus, only by controlling the movement of the push-pull assembly, it can be realized that the redundant water of the mop is squeezed out by the extrusion between the pressing plate and the water squeezing tank. The user does not need to twist the mop forcefully to squeeze the water, which reduces the fatigue of the user and can effectively improve the water squeezing efficiency of the mop.

[0009] In some embodiments, the top edge of the water squeezing tank is provided with an inclined edge, and the inclined edge is inclined towards the inside of the water squeezing tank along the direction towards the bottom of the water squeezing tank.

[0010] Thus, through such a setting, when the user squeezes water, the water splashed on the top of the water squeezing tank can flow back into the water squeezing tank along the inclined edge, avoiding affecting the mopping environment.

[0011] In some embodiments, the push-pull assembly includes a chute structure arranged on the water squeezing tank and a driving rotating shaft rotatably arranged on the water squeezing tank. A slider structure is arranged on the pressing plate, and the slider structure is arranged on the chute structure so that the pressing plate is slidably arranged in the water squeezing tank. A first connecting rod extends along the radial direction of the driving rotating shaft, the first connecting rod is hinged with a second connecting rod, and the other end of the second connecting rod is hinged with the pressing plate.

[0012] Thus, with such a configuration, when the driving rotating shaft rotates, it can drive the first connecting rod to rotate, and then drive the second connecting rod, and push the pressing plate, so that the pressing plate slides along the chute structure, realizing the movement of the pressing plate closer to or away from an inner side wall of the juice squeezing tank. When the mop is placed in the juice squeezing tank, rotating the driving rotating shaft can drive the pressing plate to move and squeeze the mop.

[0013] In some embodiments, the chute structure includes a first chute and a second chute. The first chute is disposed above the second chute. The slider structure includes a first slider and a second slider. The first slider is slidably disposed in the first chute, and the second slider is slidably disposed in the second chute.

[0014] Thus, with such a configuration, through the setting of the two sets of chutes and sliders, the movement of the pressing plate can be made more stable.

[0015] In some embodiments, the length of the first chute is longer than that of the second chute, and a downwardly curved section is provided on one side of the first chute close to the driving rotating shaft.

[0016] Thus, with such a configuration, when the pressing plate is opened, the upper part can be relatively farther away from the inner side wall of the juice squeezing tank than the lower part, and then the top of the juice squeezing tank can be opened, making it easier to put the mop into the juice squeezing tank.

[0017] In some embodiments, at least two sets of the first connecting rod and the second connecting rod are provided.

[0018] Thus, with such a configuration, the driving of the pressing plate can be made more stable, and the stability of the overall structure can be improved.

[0019] In some embodiments, an elastic member is further provided between the juice squeezing tank and the driving rotating shaft for driving the driving rotating shaft to rotate so that the pressing plate is away from an inner side wall of the juice squeezing tank.

[0020] Thus, with such a configuration, the elastic member can be used to automatically open the pressing plate, improving the user experience.

[0021] In some embodiments, the mounting structure includes a strip-shaped mounting slot provided on the juice squeezing tank.

[0022] Thus, with such a configuration, the strip-shaped mounting slot can be inserted into the barrel body of the mop washing bucket, thereby realizing the installation of the juice squeezing device.

[0023] According to another aspect of the present invention, a mop washing bucket is provided, including a barrel body, and the above-mentioned juice squeezing device is mounted on the barrel body.

[0024] The mopping bucket of the present utility model is provided with the above-mentioned water extraction device, which can effectively reduce the fatigue of the user when wringing out the mop and can effectively improve the water extraction efficiency of the mop.

[0025] In some embodiments, a flanging is provided at the top of the bucket body, and a notch for installing the water extraction device is provided on the flanging.

[0026] Thus, by such a setting, the water extraction device can be installed on the notch of the mopping bucket, so that the water extraction device will not slide randomly on the mopping bucket during use. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0038] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0039] Figure 1 Schematically shows the structural schematic of a water squeezing device according to an embodiment of the present utility model. Refer to Figure 1 As shown, the water squeezing device of the present utility model includes a water squeezing tank 1, a pressing plate 2 and a pushing and pulling assembly 3. Among them, the water squeezing tank 1 is square, and a first inlet is provided at its top. The pressing plate 2 is slidably arranged in the water squeezing tank 1, and the pushing and pulling assembly 3 is arranged in the water squeezing tank 1 and connected to the pressing plate 2 to drive the pressing plate 2 to approach or move away from an inner side wall of the water squeezing tank 1. Thus, when the pressing plate 2 approaches the inner wall of the water squeezing tank 1, it can squeeze the mop to squeeze out the water. Specifically, refer to Figure 1 As shown, the water squeezing tank 1 is square in shape, and one side and the top surface thereof are both in an open state. The pressing plate 2 is a plate structure, and its size matches the side wall size of the water squeezing tank 1 and is arranged at the open side surface position of the water squeezing tank 1. Driven by the pushing and pulling assembly 3, the pressing plate 2 slides in the water squeezing tank 1 to approach or move away from the side wall of the water squeezing tank 1 opposite to the pressing plate 2. A plurality of leakage holes 12 are provided on the side wall and / or bottom of the water squeezing tank 1. Thus, after the water of the mop is squeezed out, the water can leak out from the leakage holes 12. Among them, the leakage holes 12 provided on the side wall of the water squeezing tank 1 can be provided only on the side wall of the water squeezing tank 1 opposite to the pressing plate 2, or can be provided on each side wall of the water squeezing tank 1 at the same time. The shape of the leakage holes 12 can be common shapes such as circular and square, or other irregular shapes or designed according to user needs. At the same time, leakage holes 12 can also be provided on the pressing plate 2, which can improve the drainage efficiency.

[0040] In some possible embodiments, the pushing and pulling assembly 3 may include a chute structure provided on the water squeezing tank 1 and a driving rotating shaft 31 rotatably arranged on the water squeezing tank 1. Specifically, refer to Figure 1 and Figure 2As shown, both ends of the driving rotating shaft 31 can be rotatably connected to the side walls on both sides of the extrusion plate 2 in the squeezing water tank 1. A first connecting rod 32 extends radially along the driving rotating shaft 31, and the first connecting rod 32 is hinged to a second connecting rod 33. The other end of the second connecting rod 33 is hinged to a side surface of the extrusion plate 2 facing the outside of the squeezing water tank 1. At the same time, slider structures are arranged on both sides of the extrusion plate 2, and chute structures are arranged on the side walls on both sides of the extrusion plate 2 in the squeezing water tank 1, so that the slider structures cooperate with the chute structures, enabling the slider structures to slide in the chute structures. Thus, by rotating the driving rotating shaft 31, the first connecting rod 32 can be driven to move. When the first connecting rod 32 moves, it will drive the second connecting rod 33 to move, and further push or pull the extrusion plate 2 to move closer to or away from an inner side wall of the squeezing water tank 1. Among them, the chute structure can be a through groove penetrating the side wall of the squeezing water tank 1 or a blind groove not penetrating the side wall of the squeezing water tank 1. At the same time, in order to facilitate the user to control the rotation of the driving rotating shaft 31, a handle 34 can also be extended and arranged in the middle of the driving rotating shaft 31, so that the user can control the rotation of the driving rotating shaft 31 through the handle 34. Specifically, referring to Figure 1 As shown, the handle 34 is detachably mounted on the first connecting rod 32, so that the handle 34 can be mounted when needed to improve the storage performance.

[0041] In addition, in some other possible embodiments, the chute structure may include a first chute 41 and a second chute 42. The first chute 41 is located above the second chute 42, and both the first chute 41 and the second chute 42 can be linear chutes. The slider structure may include a first slider 21 and a second slider 22, and the first slider 21 is slidably arranged in the first chute 41, and the second slider 22 is slidably arranged in the second chute 42, so as to improve the stability of the extrusion plate 2 when sliding. Referring to Figure 1 and Figure 2As shown, in some other possible embodiments, the upper first chute 41 can be further designed such that the length of the first chute 41 is longer than that of the second chute 42, and at one end of the first chute 41 away from the side wall for squeezing water in the squeezing tank 1, i.e., at one end of the first chute 41 close to the driving rotating shaft 31, a downwardly curved section 411 is provided. Among them, the downwardly curved section 411 is an arc section formed with the end close to the driving rotating shaft 31 of the second chute 42 as the center of the circle. By setting it like this, when the squeezing plate 2 is opened, the second slider 22 at the bottom will reach the limit position first. At this time, under the drive of the driving rotating shaft 31, the first chute 41 will continue to slide within the downwardly curved section 411, so that the top of the squeezing plate 2 is continuously driven, making the squeezing plate 2 form a state where the top inclines outward from the squeezing tank 1. This can enable the upper part of the squeezing plate 2 to be relatively farther away from the inner side wall of the squeezing tank 1 than the lower part when the squeezing plate 2 is actively opened, and further enable the top of the squeezing tank 1 to be opened, making it easier to put the mop into the squeezing tank 1. It can be understood that the shape of the downwardly curved section 411 of the first chute 41 and the shapes of the first chute 41 and the second chute 42 are not necessarily the same as those described above, because as long as the width of the chute is greater than the width of the slider, the slider can perform corresponding linear or arc motions within the chute, thus reducing the requirements for the shape of the chute.

[0042] In some possible embodiments, at least two sets of the first connecting rod 32 and the second connecting rod 33 can also be provided, thereby improving the stability when driving the squeezing plate 2 to move. Refer to Figure 1 and Figure 2 As shown, in Figure 1 and Figure 2 the shown embodiment, two sets of the first connecting rod 32 and the second connecting rod 33 are provided and symmetrically arranged on the driving rotating shaft 31. Moreover, an elastic member 5 is provided between the squeezing tank 1 and the driving rotating shaft 31 for driving the driving rotating shaft 31 to rotate so that the squeezing plate 2 moves away from an inner side wall of the squeezing tank 1, so as to be able to automatically open the squeezing plate 2 by using the elastic member 5 and improve the user experience. The elastic member 5 can be a spring. One end of the spring can be connected to the driving rotating shaft 31, and the other end is connected to the bottom of the squeezing tank 1, and is set such that the spring is in a normal state when the squeezing plate 2 is in the open state. Thus, when rotating the driving rotating shaft 31 to drive the squeezing plate 2 to move close to an inner side wall of the squeezing tank 1, the spring is pulled open by the tensile force. When the driving rotating shaft 31 is released, the squeezing plate 2 will be driven by the spring to return to the open state.

[0043] The top edge of the water extraction tank 1 may also be provided with an inclined edge 11, and the inclined edge 11 is inclined towards the inside of the water extraction tank 1 along the direction towards the bottom of the water extraction tank 1, so that when the user extracts water, the water splashed on the top of the water extraction tank 1 can flow back into the water extraction tank 1 along the inclined edge 11, avoiding affecting the mopping environment. An installation structure 13 may also be provided on the water extraction tank 1. Refer to Figure 1 and Figure 2 As shown, it may be set as a strip-shaped installation slot provided on the water extraction tank 1. The installation slot is strip-shaped, so that the water extraction tank 1 can be inserted into the edge of the bucket body of the mop washing bucket through the installation slot, thereby realizing the installation of the water extraction device.

[0044] The water extraction device of the present utility model controls the movement of the extrusion plate 2 through the push-pull assembly 3. Furthermore, only by controlling the movement of the push-pull assembly 3 can the excess water of the mop be squeezed out by the extrusion between the extrusion plate 2 and the water extraction tank 1. The user does not need to twist the mop forcefully to squeeze water, reducing the fatigue of the user and effectively improving the water extraction efficiency of the mop.

[0045] Figure 3 Schematically shows the structural schematic of a mop washing bucket according to an embodiment of the present utility model. Refer to Figure 3 As shown, the mop washing bucket of the present utility model includes a bucket body 6, and the water extraction device 9 described in any of the above embodiments is installed on the bucket body 6, so that the mop washing bucket can effectively reduce the fatigue of the user when wringing out the mop and can effectively improve the water extraction efficiency of the mop.

[0046] In some possible implementation manners, a barrier body 63 is provided in the bucket body 6 of the mop washing bucket. The barrier body 63 divides the accommodation space in the bucket body 6 into a first water storage part 61 and a second water storage part 62. Among them, the barrier body 63 is integrally formed with the bucket body 6, thereby effectively avoiding the situation of mutual leakage between the two spaces that occurs when using a detachable partition in the prior art. An inward concave structure 65 is provided at the position of the barrier body 63 on the outer side of the bucket body 6. The inward concave structure 65 is used to divide the outer side of the bucket body 6 based on the first water storage part 61 and the second water storage part 62, so that the inward concave structure 65 includes a first side surface and a second side surface. The first side surface is the side surface on the outer side of the bucket body 6 of the side surface of the barrier body 63 facing the first water storage part 61, and the second side surface is the side surface on the outer side of the bucket body 6 of the side surface of the barrier body 63 facing the second water storage part 62. Such a design can effectively reduce the raw material cost used in manufacturing the bucket body 6. At the same time, a first reinforcing rib structure 64 may also be provided between the first side surface and the second side surface. Furthermore, through the setting of the first reinforcing rib structure 64, the first side surface and the second side surface can be connected to improve the relative stability between the first side surface and the second side surface. Specifically, refer to Figure 3 and Figure 4 As shown, in Figure 3And Figure 4 In the embodiment shown, one first reinforcing rib structure 64 can be provided on each of the two sides of the barrel body 6, that is, two first reinforcing rib structures 64 are provided. The top of the first reinforcing rib structure 64 is connected to the barrel body 6, and the bottom of the first reinforcing rib structure 64 is crescent-shaped. Therefore, while ensuring the structural strengthening effect of the first reinforcing rib structure 64, the cost of the first reinforcing rib structure 64 can be further reduced.

[0047] The position of the barrier body 63 in the barrel body 6 can be designed arbitrarily. However, since the barrier body 63 and the barrel body 6 are integrally formed, the position of the barrier body 63 cannot be adjusted secondarily after production. Therefore, in this embodiment, in order to make the applicable scenarios of the first water filling part 61 and the second water filling part 62 wider, the barrier body 63 is arranged in the middle of the barrel body 6 in the length direction to divide the space in the barrel body 6 into two spaces along the middle of its length direction. The shape of the barrier body 63 can actually be designed according to actual needs. The shape of the barrier body 63 can be in styles such as wavy, diagonal or straight. Specifically, referring to Figure 3 shown, in this embodiment, the shape of the barrier body 63 specifically adopts a straight style. The straight style can provide a larger use space for the first water filling part 61 and the second water filling part 62 in the barrel body 6. At the same time, the straight style can also adapt to the installation of part of the water squeezing structure, thereby improving the applicable scenarios of the mopping bucket of the present utility model and improving the applicability. At the same time, the height of the barrier body 63 can be the same as the top of the barrel body 6, or there can be a certain distance interval between the height of the barrier body 63 and the top of the barrel body 6. Specifically, in this embodiment, the height of the barrier body 63 is set to have a certain interval from the top of the barrel body 6, so that when the amount of water filled in the barrel body 6 is not much, the barrier body 63 can be used to divide the barrel body 6 into the first water filling part 61 and the second water filling part 62 to separate sewage and clean water. When separation is not required, the amount of water filled in the barrel body 6 can be increased so that the water in the barrel body 6 overflows from one side to the other side, and thus the first water filling part 61 and the second water filling part 62 can be used together. Specifically, referring to Figure 3 shown, in Figure 3 the embodiment shown, the height of the barrier body 63 can specifically be set to 3 / 4 of the height of the barrel body 6.

[0048] In some other possible embodiments, a flanging 7 may be provided at the top of the barrel body 6. The flanging 7 is a structure that bends and turns downward toward the outside of the barrel body 6. With such a design, the user can grasp the flanging 7 by hand to move or carry the barrel body 6. In order to improve the structural stability of the flanging 7 and prevent the barrel body 6 from being too heavy, when the user moves or carries the barrel body 6 by grasping the flanging 7, the flanging 7 may break or the like. A second reinforcing rib structure 71 may be provided on the inner side of the flanging 7. Among them, the inner side of the flanging 7 is the spatial position formed between the flanging 7 and the outer side surface of the barrel body 6 after the flanging 7 turns downward toward the outside. For the designed second reinforcing rib structure 71, in order to improve its structural strengthening and stabilizing effect, the structure of the second reinforcing rib structure 71 may adopt cross-shaped reinforcing ribs, so as to ensure the structural strengthening effect of the second reinforcing rib structure 71 on the flanging 7. A notch 72 for installing a water squeezing structure may also be provided on the flanging 7. Among them, the setting position, quantity and shape of the notch 72 can all be designed according to the water squeezing structure to be installed. Since the notch 72 is used for installing the water squeezing structure, in order to further improve the structural stability at the notch 72, a third reinforcing rib 73 connected to the outside of the barrel body 1 may also be provided at the notch 72 to further improve the structural stability of this part of the position. Exemplarily, referring to Figure 3 and Figure 4 as shown, in the embodiments shown in Figure 3 and Figure 4 the notch 72 may be provided only on one side of the flanging 3 of the barrel body 1 (that is, Figure 4 the side located on the left as shown). The quantity of the notch 72 is specifically set to two, and its shape is a long rectangle. The width of the notch 72 is about 1 / 3 of the width of the flanging 3. The third reinforcing rib 73 is specifically provided on the outside of the barrel body 1. The third reinforcing rib 73 is connected to the position of the notch 72 to prevent the water squeezing structure from being too heavy and causing the barrel body 1 to break and be unable to bear it. The second reinforcing rib 33 is specifically provided as a long strip plate. Its top is connected to the flanging 3, and its bottom is provided with an arc structure to reduce the manufacturing cost and prevent the protrusion of the reinforcing rib from scratching the user or other articles.

[0049] In some other possible embodiments, wheels 8 may also be provided at the bottom of the barrel body 6. Four wheels 8 are provided and are arranged at the four corner positions at the bottom of the barrel body 6.
