TECHNICAL FIELD

[0001] The utility model relates to domestic articles technical field especially relates to a squeeze water roller, squeeze water subassembly and mop bucket. BACKGROUND

[0002] The flat mop is a kind of modern cleaning tool, which is composed of a flat mop head and a rod body, and the mop head is attached with replaceable wiping material, which makes the flat mop adapt to the cleaning needs of different ground, such as wood floor, ceramic tile, carpet, etc.The use of flat mop is very simple and convenient, because the mop head is flat, it can completely fit the ground when in contact, and it can cover a large cleaning area at one time, with high efficiency.

[0003] In order to squeeze the mop head, the existing flat mop adopts sliding scraping or rolling extrusion to squeeze water. Among them, the sliding scraping mode is to scrape the wiping material by setting a water scraping plate to squeeze out the water in the wiping material. Such a water squeezing method has large wear on the wiping material. The rolling extrusion mode is to roll and press the wiping material on the mop head by setting a water squeezing roller, and the water in the wiping material is squeezed out by the water squeezing protrusions on the outer periphery of the water squeezing roller. Compared with the water scraping plate, the water squeezing roller has lower damage to the wiping material, but the existing water squeezing roller is mostly integrally formed by hard plastic. In order to ensure the labor-saving of mop head pulling, the water squeezing protrusions on the outer periphery of the water squeezing roller cannot be set too high, and the single water squeezing effect is lower than that of the water scraping plate.

[0010] In the preferred technical scheme of the utility model, the material of the roller body is plastic, and the material of the water squeezing protrusion is flexible plastic, rubber or silicone.

[0011] In the preferred technical scheme of the utility model, the water squeezing protrusions are convex points uniformly distributed on the outer peripheral side surface of the roller body.

[0012] In a preferred embodiment of this invention, the dewatering protrusion is a raised ridge, and the raised ridge is parallel to the axial direction of the roller body;

[0013] Several protruding ridges are evenly distributed on the outer peripheral side of the roller.

[0014] In a preferred embodiment of this invention, a plurality of grooves are evenly distributed around the outer peripheral side of the roller body, and the grooves are parallel to the axial direction of the roller body.

[0015] The protruding ridges and grooves are arranged in a one-to-one correspondence, with the bottom end of the protruding ridge set inside the groove and the top end of the protruding ridge higher than the top end of the groove.

[0016] In a preferred embodiment of this invention, connecting shaft portions are coaxially arranged at both ends of the roller body;

[0017] The roller body has annular grooves at both ends, which are located between the groove and the connecting shaft and are connected to the groove.

[0020] In a preferred embodiment of this utility model, the protruding ridge includes a connecting portion and a pressing portion, the connecting portion being disposed within a groove, and the pressing portion extending out of the groove;

[0021] The cross-sectional area of ​​the extrusion section gradually decreases along the direction away from the groove;

[0022] Preferably, the long sides of the extrusion section are rounded to avoid stress concentration and are also more conducive to the extrusion deformation of the extrusion section.

[0023] The second objective of this utility model is to provide a water-squeezing component:

[0024] It includes a sleeve, which has a wringing hole for inserting a mop head, and a wringing roller as described above is rotatably installed in the wringing hole.

[0044] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0045] To wring out water from the mop head, existing flat mops use either sliding scraping or rolling squeezing methods. Sliding scraping involves using a squeegee to scrape the surface and squeeze out water, but this method causes significant wear and tear on the surface. Rolling squeezing uses a wringing roller to press the surface on the mop head, squeezing out water through protrusions on the outer edge of the roller. Compared to a squeegee, wringing rollers are less damaging to the surface, but most existing wringing rollers are made of rigid, one-piece molded plastic. To ensure easier mop head pulling, the protrusions on the outer edge of the wringing roller cannot be set too high, resulting in a lower squeezing effect per pass compared to a squeegee.

[0046] Example 1

[0047] To address the aforementioned issues, Embodiment 1 provides a soft-hard combined squeezing roller 100 to improve the single-pass squeezing effect of rolling extrusion.

[0048] like Figure 1 As shown, a dewatering roller 100:

[0049] Includes a rigid roller body 120;

[0050] The outer periphery of the roller body 120 is provided with a number of soft water-squeezing protrusions 110 at intervals.

[0051] The roller body 120 and the squeezing protrusion 110 are made of different materials. Preferably, the squeezing roller is processed by a two-stage injection molding process. First, the roller body 120 is injection molded, and then the squeezing protrusion 110 is injection molded on the roller body 120.

[0052] For example, the roller body 120 can be made of plastic, and the squeezing protrusions 110 can be made of any one of flexible plastic, rubber or silicone.

[0053] Compared to existing rigid plastic one-piece wringer rollers, the soft wringer protrusion 110 can be made higher without affecting the mop head's pull-out action. When squeezing the mop head to squeeze out water, the soft wringer protrusion 110 can provide greater friction. The soft wringer protrusion 110 can obtain a larger squeezing area when it is squeezed and deformed. Compared to existing rigid plastic one-piece wringer rollers, the wringer roller 100 of this embodiment has a higher single-pass squeezing effect when rolling and squeezing.

[0054] Example 2

[0055] Example 2 builds upon Example 1 to create a design that is both functional and aesthetically pleasing, thereby enhancing the user experience.

[0056] like Figure 1 As shown, Example 2 is basically the same as Example 1 in terms of features, except that:

[0057] The roller body 120 and the squeezing protrusion 110 may be the same or different colors. Preferably, the roller body 120 and the squeezing protrusion 110 are set to different colors. In practical applications, the squeezing roller 100 can be installed on the flat mop bucket 400 or the sleeve 300 on the flat mop. When working, pulling out the mop head will drive the squeezing roller 100 to rotate. The different color design can make the rotation of the squeezing roller 100 clearly visible, so that the user can visually feel that the squeezing roller 100 is rotating and squeezing water.

[0058] Example 3

[0059] Example 3 further designs the water-squeezing protrusion 110 based on Example 1.

[0060] Example 3 is basically the same as Example 1, except that:

[0061] The water-squeezing protrusions 110 are protrusions evenly distributed on the outer peripheral side of the roller body 120. The protrusions can not only increase the friction between the roller body 120 and the mop head, but also apply squeezing force to the mop head to squeeze out water during operation.

[0062] Example 4

[0063] Example 4 further designs the water-squeezing protrusion 110 based on Example 1 or Example 2.

[0064] like Figures 1-4 As shown, Example 4 is basically the same as Example 1 or Example 2 in terms of features, except that:

[0065] The dewatering protrusion 110 is a ridge 111, which can be linear, spiral, or wavy. Preferably, the ridge 111 is linear and parallel to the axial direction of the roller body 120.

[0066] Several protruding ridges 111 are evenly distributed on the outer side of the roller body 120. The protruding ridges 111 can not only increase the friction between the roller body 120 and the mop head, but also apply squeezing force to the mop head to squeeze out water during operation.

[0067] In this embodiment, the outer circumference of the roller body 120 is evenly distributed with a plurality of grooves 121 for accommodating the bottom of the protrusion 111;

[0068] The protruding ridge 111 and the groove 121 are arranged in a one-to-one correspondence. The bottom end of the protruding ridge 111 is set in the groove 121, and the top end of the protruding ridge 111 is higher than the top end of the groove 121.

[0069] In this embodiment, the roller body 120 is provided with connecting shaft portions 123 coaxially at both ends;

[0070] The roller body 120 has annular grooves 122 at both ends. The annular grooves 122 are located between the groove 121 and the connecting shaft portion 123, and the annular grooves 122 communicate with the groove 121.

[0071] In this embodiment, in order to facilitate the processing and manufacturing of the protrusion 111, a connecting ring 112 is provided in the annular groove 122. The material of the connecting ring 112 is the same as that of the squeezing protrusion 110. The connecting ring 112 connects the protrusion 111. This design allows the protrusion 111 and the connecting ring 112 to be integrally injection molded on the roller body 120, which is simple and convenient to process and manufacture. The connecting ring 112 connects each protrusion 111 into a whole, resulting in better overall structural strength.

[0072] Example 5

[0073] Example 5, based on Example 4, adds a rigid squeezing section to improve the squeezing effect, assisting the soft squeezing protrusion 110 in squeezing water.

[0074] like Figure 5 As shown, Example 5 is basically the same as Example 4 in terms of features, except that:

[0075] The outer circumference of the roller body 120 is evenly distributed with a number of protrusions 124 parallel to the axial direction of the roller body 120. The protrusions 124 and the grooves 121 are staggered. The material of the protrusions 124 is the same as that of the roller body 120. The top of the protrusion 111 is higher than the top of the protrusion 124. When working, the rotation of the roller body 120 can realize the alternating squeezing of the mop head by soft (protrusion 111) and hard (protrusion 124). Compared with squeezing water by using only the protrusion 111, the single squeezing effect can be further enhanced.

[0076] Example 6

[0077] In Example 6, based on the above examples, the structure of the protruding ridge 111 is further improved to enhance the water-squeezing effect.

[0078] like Figure 4 As shown, Example 6 is basically the same as Example 4 in terms of features, except that:

[0079] The protruding ridge 111 includes a connecting part 1111 and a pressing part 1112. The connecting part 1111 is disposed in the groove 121, and the pressing part 1112 extends out of the groove 121.

[0080] The cross-sectional area of ​​the extrusion section 1112 gradually decreases along the direction away from the groove 121. This design can reduce the resistance when the mop head is pulled out and initially contacts the wringer 100, and also facilitate the extrusion deformation of the extrusion section 1112.

[0081] Preferably, the long sides of the extrusion section 1112 are rounded. The rounded corner transition avoids stress concentration and is also more conducive to the extrusion deformation of the extrusion section 1112.

[0082] Example 7

[0083] Example 7 provides a dewatering assembly with a dewatering roller 100 based on the above examples. Specifically, the dewatering assembly is a dewatering sleeve mounted on the rod of a flatbed slide.

[0084] like Figure 6 As shown, a dewatering assembly:

[0085] It includes a sleeve 300, which has a wringing hole for inserting a mop head, and the wringing roller 100 in the above embodiment is rotatably installed in the wringing hole.

[0086] In this embodiment, rollers are installed on the inner wall of the squeezing hole;

[0087] The roller and the squeezing roller 100 are arranged opposite to each other, and there is a squeezing channel between the roller and the squeezing roller 100 for the mop head to pass through.

[0088] A guide channel is provided on the inner wall of the squeezing hole;

[0089] The end of the squeezing roller 100 is slidably disposed in the guide channel;

[0090] As the mop head is inserted, the gap between the guide channel and the roller decreases.

[0091] Preferably, the mop head moves vertically, and the guide channel has an upper end and a lower end.

[0092] When wringing out water, insert the mop head of the flat mop into the wringing channel and apply a downward force to the mop handle 200. As the mop head moves vertically downward, it drives the wringing roller 100 to roll. During this process, the wringing roller 100 is always located at the lower end of the guide channel. The mop head is squeezed to squeeze out most of the water, thus drying the mop.

[0093] After squeezing out the water, an upward force is applied to the mop handle 200 of the flat mop. When the mop head is pulled vertically upward, the movement of the mop head drives the squeezing roller 100 to roll and forces the squeezing roller 100 to move upward along the guide channel. This increases the distance between the squeezing roller 100 and the insert roller, and the force exerted by the squeezing and roller on the mop head gradually decreases, making it easier to pull out the mop head.

[0094] Example 8

[0095] Example 8 provides a mop bucket 400 with a wringer roller 100, based on the above examples.

[0096] like Figure 7 As shown, a mop bucket 400:

[0097] Including the barrel body and the lid covering it;

[0098] The bucket lid is provided with a through hole for inserting a mop head, and the wringer 100 of the above embodiment is rotatably installed in the through hole.
