Description

Technical Field

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

[0002] When the existing mop wringing head is installed on the mop washing bucket, it generally needs to occupy nearly half of the top surface position of the mop washing bucket, so as to ensure that during the use of the mop wringing head, the three sides of the top of the mop washing bucket are used for support to ensure the structural stability of the mop wringing head during use. However, in actual use, the structure of this mop washing bucket cannot flexibly change the position of the mop wringing head. Summary of the Utility Model

[0003] The embodiments of the utility model provide a mop wringing head 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 mop wringing head is provided, including

[0005] An installation shell, provided with an installation structure for installing on the mop washing bucket;

[0006] A wringing structure, arranged on the top surface of the installation shell;

[0007] There are two groups of the installation structures, and one group is respectively arranged on each of the two sides of the installation shell. At the bottom of the two end faces of the installation structure, there are first grooves for cooperating with the flanges on the mop washing bucket. On one side of the first groove away from the installation shell, there is a hook structure, and the hook structure is used for hooking into the inner side of the flange on the mop washing bucket.

[0008] The mop wringing head of the utility model is provided with only one group of installation structures on each of its two sides, and the installation structure is provided with grooves for cooperating with the flanges on the mop washing bucket. The hook structure on the groove is further fastened with the flange. The setting of the hook structure can improve the connection performance between the installation shell and the flange on the mop washing bucket during installation, and thus the stable installation of the mop wringing head can be realized only by connecting with the two opposite sides of the top of the mop washing bucket. It enables the mop wringing head to be flexibly replaced at the installation position on the top of the mop washing bucket (such as installed on the left side, middle or right side), improves the applicability of the application scenarios of the mop wringing head, and can also effectively improve the structural stability of the overall mop wringing head.

[0009] In some embodiments, a first reinforcing rib structure is arranged on the inner side surface of the installation structure.

[0010] Thus, by such setting, the structural stability when the mop wringing head is installed on the mop washing bucket can be further enhanced.

[0011] In some embodiments, the first reinforcing rib structure is a reinforcing plate parallel to the side end face of the mounting structure, and a second groove is provided on the first reinforcing rib structure, and the structure of the second groove is the same as that of the first groove.

[0012] Thus, by such a setting, the structural stability of the mounting structure can be enhanced, and the mounting stability when the overall mop wringing head is mounted on the mop washing bucket can also be improved.

[0013] In some embodiments, a plurality of the first reinforcing ribs are provided, and the spacing between adjacent first reinforcing ribs is not greater than 25 mm.

[0014] Thus, by such a setting, while ensuring the structural reinforcement of the mounting structure by the first reinforcing ribs, the weight of the mounting structure can be reduced, making the overall structure more reasonable.

[0015] In some embodiments, the wringing structure includes a cylindrical side wall extending towards the bottom surface of the mounting shell and a bottom plate provided at the bottom of the cylindrical side wall. A plurality of rows of first leak hole groups are uniformly arranged on the cylindrical side wall. Each first leak hole group includes a plurality of first leak holes arranged in parallel, and a plurality of second leak holes are uniformly arranged on the bottom plate.

[0016] Thus, by such a setting, the mop can be wrung through the wringing structure.

[0017] In some embodiments, a second reinforcing rib structure is provided between adjacent first leak hole groups, and the second reinforcing rib structure is connected to the bottom plate.

[0018] Thus, by such a setting, the structural stability of the wringing structure itself can be enhanced.

[0019] In some embodiments, the top surface height of the wringing structure is lower than the top surface height of the mounting shell, and the top surface of the mounting shell is arranged to be inclined towards the top surface of the wringing structure.

[0020] Thus, by such a setting, when the mop is being wrung, the excess water droplets that drip can flow back into the mop washing bucket along the inclined top surface of the wringing structure.

[0021] According to another aspect of the present invention, there is provided a mop washing bucket, including a bucket body, a flanging is provided at the top of the bucket body, and the above-mentioned mop wringing head is mounted on the flanging.

[0022] By providing the above-mentioned mop wringing head, the mop washing bucket of the present invention can flexibly change the mounting position of the mop wringing head on the top of the mop washing bucket (such as being mounted on the left side, the middle or the right side), improving the applicability of the application scenarios of the mop wringing head, and effectively enhancing the structural stability of the overall mop wringing head.

[0023] In some embodiments, a barrier is integrally formed inside the bucket body, dividing the space inside the bucket body into a first water storage part and a second water storage part;

[0024] An inner concave structure is provided at the position of the barrier on the outer side of the bucket body. The inner concave structure 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 of the side surface of the barrier facing the first water storage part, and the second side surface is the side surface on the outer side of the bucket body of the side surface of the barrier facing the second water storage part;

[0025] A third reinforcing rib structure is provided between the first side surface and the second side surface.

[0026] Thus, through such a setting, it can be ensured that the first water storage part and the second water storage part inside the bucket body are completely separated, and the situation of seepage pollution of the clean water will not occur.

[0027] In some embodiments, a fourth reinforcing rib structure is provided on the inner side of the flanging.

[0028] Thus, through such a setting, the structural stability of the flanging can be effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] 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.

[0040] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0041] Figure 1 Schematically shows the overall structure of the mop wringing head of an embodiment of the present utility model. Referring to Figure 1 as shown, the mop wringing head of the present utility model includes an installation shell 1 and a wringing structure 2 disposed on the top surface of the installation shell 1. An installation structure 3 is provided on the installation shell 1, and a set of installation structures 3 is provided on each of the two opposite sides of the installation shell 1, so that the wringing structure 2 can be installed on the two opposite flanges of the mop washing bucket by means of the two sets of installation structures 3, so that the installation position of the wringing structure 2 on the mop washing bucket can be flexibly adjusted. The installation structure 3 includes a first groove 31 for cooperating with the flange, that is, among the dimensions of the first groove 31, at least the width corresponds to the dimension of the flange, so that both side edges in the first groove 31 can be close to the inner side edge and the outer side edge of the flange, enabling the wringing structure 2 to be stably installed on the mop washing bucket through the installation structure 3. At the same time, a hook structure 32 is provided at the end of the side edge on the side of the first groove 31 away from the installation shell 1, that is, a hook structure 32 is provided at the lower end of the side edge of the first groove 31 that is close to the outer side edge of the flange. When the first groove 31 of the installation structure 3 is installed and cooperated with the flange of the mop washing bucket, the hook structure 32 will hook into the inside of the flange to improve the installation stability of the installation structure 3. At the same time, when the mop wringing head is installed on the mop washing bucket, the pressure exerted on the mop washing bucket can be evenly distributed, improving the overall structural stability of the mop wringing head.

[0042] In order to further improve the installation stability of the mop wringing head and its structural stability, a first reinforcing rib structure 33 can also be provided on the inner side of the installation structure 3. The number of the first reinforcing rib structures 33 can be set to be multiple, and they are arranged at equal intervals, and can be flexibly designed according to the actual situation. The first reinforcing rib structure 33 can be a rib structure or a reinforcing plate structure. When the first reinforcing rib structure 33 is a rib structure, it can effectively reduce the use of materials and the overall weight on the premise of ensuring the installation stability of the installation structure 3 and its structural stability. When the first reinforcing rib structure 33 is a reinforcing plate structure, a second groove 34 can be further provided on the reinforcing plate structure to further adapt to the flange on the mop washing bucket, so as to better improve the installation stability and structural stability of the mop wringing head.

[0043] Exemplarily, referring to Figure 2 as shown, in Figure 2 the shown embodiment, the end faces on both sides of the installation structure 3 are connected to the installation shell 1. The top surface and the outer side surface of the installation structure 3 connect the end faces on both sides, and there is a gap between the top surface and the installation shell 1 to avoid the dripping water of the mop flowing along the installation structure 3 to the outside of the mop washing bucket during use. The first reinforcing rib structure 33 is a reinforcing plate structure. A plurality of first reinforcing ribs are parallel to each other and arranged at equal intervals on the inner side of the installation structure 3. The adjacent reinforcing plate structures are spaced about 25 mm apart. The reinforcing plate structure is connected to a part of the installation shell 1 and is also connected to the inner sides of both the top surface and the outer side surface of the installation structure 3. A second groove 34 is provided on the reinforcing plate structure, and the structure of the second groove 34 is the same as that of the first groove 31. The first groove 31 on the installation structure 3 is a rectangular groove with an opening at the bottom, and a hook structure 32 is provided on the side away from the installation shell 1 in the first groove 31. The orientation of the hook structure 32 is towards the installation shell 1, so as to cooperate with the flange on the mop washing bucket to stably install the entire mop wringing head on the mop washing bucket and ensure the structural stability of the mop wringing head installed on the mop washing bucket.

[0044] For the wringing structure 2, it is mainly used to wring the mop. The wringing structure 2 can be designed differently according to the specific type of mop. Exemplarily, Figure 1Schematically shows the structural schematic of the water extraction structure 2 of the mop wringing head according to an embodiment of the present utility model. The water extraction structure 2 of this embodiment is a water extraction structure 2 for mop types such as cotton mops. Specifically, the water extraction structure 2 may include a cylindrical side wall 21 extending towards the bottom surface of the mounting shell 1 and a bottom plate 22 provided at the bottom of the cylindrical side wall 21. The cylindrical side wall 21 is provided with a first leakage hole 23, and the bottom plate 22 is provided with a second leakage hole 24, so that the water squeezed out from the cotton mop can leak from the first leakage hole 23 and the second leakage hole 24 into the mop washing bucket. Among them, the first leakage holes 23 provided on the cylindrical side wall 21 can be evenly distributed and arranged side by side on the cylindrical side wall 21 to form a plurality of columns of first leakage hole groups evenly distributed on the cylindrical side wall 21 to increase the number of the first leakage holes 23. And the second leakage holes 24 can also be evenly distributed with the center of the bottom plate 22 as the center to increase the number of the second leakage holes 24. In order to improve the structural strength of the water extraction structure 2, a second reinforcing rib structure 25 can be provided between the adjacent first leakage hole groups to improve the structural strength of the cylindrical side wall 21. Among them, the second reinforcing rib structure 25 can be a rib structure, and the second reinforcing rib structure 25 can be provided on the inner side of the cylindrical side wall 21 and connected to the bottom plate 22, so as to be able to strengthen the structural strength of both the cylindrical side wall 21 and the bottom plate 22 at the same time. In some other possible embodiments, the top surface height of the water extraction structure 2 is lower than the top surface height of the mounting shell 1, and the top surface of the mounting shell 1 is arranged to be inclined towards the top surface of the water extraction structure 2. Such a setting can enable the water on the mop to flow along the inclined top surface into the water extraction structure 2 when the water drips onto the top surface of the mounting shell 1, and flow into the mop washing bucket through the leakage holes on the water extraction structure 2, avoiding the need for secondary cleaning due to the dripping water falling outside the mop washing bucket.

[0045] Specifically, referring to Figure 1 as shown, in Figure 1In the illustrated embodiment, the mounting shell 1 is specifically a rectangular structure. The water squeezing structure 2 is arranged at the top of the mounting hole, and the mounting structure 3 is arranged on both sides of the mounting shell 1. The top surface of the mounting shell 1 slopes downward towards its middle, and the water squeezing structure 2 is arranged in the middle of the top surface of the mounting shell 1. The water squeezing structure 2 includes a cylindrical side wall 21 and a bottom plate 22. The top of the cylindrical side wall 21 is connected to the top surface of the mounting shell 1, and the bottom of the cylindrical side wall 21 is provided with a bottom plate 22. The cylindrical side wall 21 is arranged as a conical cylinder structure with a larger top and a smaller bottom. Twelve columns of first leakage hole groups are evenly arranged on the cylindrical side wall 21, and each column of the first leakage hole group is provided with five first leakage holes 23. Since the cylindrical side wall 21 is arranged as a conical cylinder structure with a larger top and a smaller bottom, the shape of the first leakage hole 23 is trapezoidal. The size of the first leakage hole 23 located in the upper part is relatively large, and the size of the first leakage hole 23 located in the lower part is relatively small. The bottom plate 22 is circular, and six second leakage holes 24 are evenly arranged on the bottom plate 22. The shape of the second leakage hole 24 is a sector ring shape. A strip-shaped second reinforcing rib structure 25 is arranged between adjacent first leakage hole groups on the cylindrical side wall 21. The second reinforcing rib structure 25 is connected to both the cylindrical side wall 21 and the bottom plate 22, thereby effectively strengthening the structural strength of the overall structure.

[0046] For the mop wringing head of the present utility model, only a set of mounting structures 3 are respectively arranged on its two sides, and grooves are arranged on the mounting structures 3 to cooperate with the flanges on the mop washing bucket. The hook structures 32 on the grooves are further fastened with the flanges. The setting of the hook structures 32 can improve the connection performance between the mounting shell 1 and the flanges on the mop washing bucket during installation, and thus the stable installation of the mop wringing head can be achieved only by connecting with the two opposite sides at the top of the mop washing bucket. The mop wringing head can be flexibly replaced at the installation positions on the top of the mop washing bucket (such as on the left, in the middle or on the right), improving the applicability of the application scenarios of the mop wringing head, and effectively improving the structural stability of the overall mop wringing head.

[0047] The present utility model also provides a mop washing bucket. Figure 3 Schematically showing the overall structural schematic of the mop washing bucket according to an embodiment of the present utility model, referring to Figure 3 as shown, the mop washing bucket includes a bucket body 5. A flange 6 is arranged at the top of the bucket body 5, and the mop wringing head 4 of any one of the above-described embodiments is arranged on the flange 6, so that it has the effect of being able to flexibly replace the installation position of the mop wringing head 4 on the top of the mop washing bucket (such as on the left, in the middle or on the right), improving the applicability of the application scenarios of the mop wringing head 4, and effectively improving the structural stability of the overall mop wringing head 4.

[0048] In some possible embodiments, a barrier 53 is provided inside the barrel body 5 of the mop washing bucket. The barrier 53 divides the accommodation space inside the barrel body 5 into a first water filling part 51 and a second water filling part 52. Among them, the barrier 53 is integrally formed with the barrel body 5, 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 55 is provided at the position of the barrier 53 on the outer side of the barrel body 5. The inward concave structure 55 is used to divide the outer side of the barrel body 5 based on the first water filling part 51 and the second water filling part 52, so that the inward concave structure 55 includes a first side surface and a second side surface. The first side surface is the side surface on the outer side of the barrel body 5 of the side of the barrier 53 facing the first water filling part 51, and the second side surface is the side surface on the outer side of the barrel body 5 of the side of the barrier 53 facing the second water filling part 52. Such a design can effectively reduce the raw material cost used in manufacturing the barrel body 5. At the same time, a third reinforcing rib structure 54 can be provided between the first side surface and the second side surface. Furthermore, through the setting of the third reinforcing rib structure 54, 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, referring to Figure 3 and Figure 4 shown, in the embodiment shown in Figure 3 and Figure 4 one third reinforcing rib structure 54 can be provided on each side of the barrel body 5, that is, two are provided. The top of the third reinforcing rib structure 54 is connected to the barrel body 5, and the bottom of the third reinforcing rib structure 54 is crescent-shaped. Thus, while ensuring the structural strengthening effect of the third reinforcing rib structure 54, the cost of the third reinforcing rib structure 54 can be further reduced.

[0049] The position of the barrier 53 inside the barrel body 5 can be designed arbitrarily. However, since the barrier 53 is integrally formed with the barrel body 5, the position of the barrier 53 cannot be adjusted secondarily after production is completed. Therefore, in this embodiment, in order to make the applicable scenarios of the first water filling part 51 and the second water filling part 52 more extensive, the barrier 53 is provided in the middle of the barrel body 5 in the length direction to divide the space inside the barrel body 5 into two spaces along the middle of its length direction. In fact, the shape of the barrier 53 can also be designed according to actual needs. The shape of the barrier 53 can be in styles such as wavy, diagonal or straight. Specifically, referring to Figure 3As shown, in this embodiment, the shape of the barrier 53 is specifically a straight-line style. The straight-line style can provide a larger usable space for the first water storage part 51 and the second water storage part 52 in the barrel body 5. At the same time, the straight-line style can also adapt to the installation of a part of the water extraction structure, thereby improving the applicable scenarios of the mop washing bucket of the present utility model and enhancing the applicability. At the same time, the height of the barrier 53 can be the same as the top of the barrel body 5, or there can be a certain distance interval between it and the top of the barrel body 5. Specifically, in this embodiment, the height of the barrier 53 is set to have a certain interval from the top of the barrel body 5, so that when the amount of water in the barrel body 5 is not much, the barrier 53 can be used to separate the first water storage part 51 and the second water storage part 52 to separate sewage and clean water. When separation is not required, the amount of water in the barrel body 5 can be increased, so that the water in the barrel body 5 overflows from one side to the other side, and then the first water storage part 51 and the second water storage part 52 can be used together. Specifically, referring to Figure 3 As shown, in Figure 3 the embodiment shown, the height of the barrier 53 can specifically be set to 3 / 4 of the height of the barrel body 5.

[0050] The flanging 6 is a structure that bends and turns downward to the outside of the barrel body 5. Through such a design, the user can grasp the flanging 6 with the hand to move or carry the barrel body 5. In order to improve the structural stability of the flanging 6 and prevent the barrel body 5 from being too heavy and the flanging 6 from breaking when the user moves or carries the barrel body 5 by grasping the flanging 6, a fourth reinforcing rib structure 61 can be provided on the inner side of the flanging 6. Among them, the inner side of the flanging 6 is the space position formed between the flanging 6 and the outer side surface of the barrel body 5 after the flanging 6 turns downward to the outside. For the designed fourth reinforcing rib structure 61, in order to improve its structural strengthening and stabilizing effect, the structure of the fourth reinforcing rib structure 61 can adopt a cross-shaped reinforcing rib, so as to ensure the structural strengthening effect of the fourth reinforcing rib structure 61 on the flanging 6.

[0051] In some other possible embodiments, a handle 7 can also be provided on the barrel body 5, and both ends of the handle 7 are respectively connected to two opposite outer side surfaces of the barrel body 5. Four wheels 8 can also be provided at the bottom of the barrel body 5, and the four wheels 8 are arranged at the four corner positions at the bottom of the barrel body 5.

[0052] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present application.
