Description

Technical Field

[0001] This utility model relates to the field of cleaning products technology, specifically to a toilet brush and a toilet brush holder. Background Technology

[0002] In daily life, cleaning the toilet is an important part of maintaining home hygiene, and the performance and ease of use of the toilet brush, as a commonly used tool for cleaning the toilet, has a key impact on the cleaning effect and user experience.

[0003] Traditional toilet brushes typically consist of a handle and a brush head, with the brush head usually made of stiff bristles or sponge material, which directly contacts the toilet surface for cleaning. However, this traditional toilet brush has several problems. On the one hand, the bristles or sponge easily retain dirt and bacteria after use, which are difficult to completely remove even after rinsing. Over time, this can lead to the growth of large amounts of bacteria, becoming a new source of pollution and posing a threat to family hygiene and health. On the other hand, replacing the brush head with a disposable brush head increases the cost of replacement. To address these technical issues, some improved toilet brush products have emerged on the market. For example, some products cover the brush head with a replaceable cleaning cloth. When installing the cleaning cloth, there are insertion holes on the brush head, into which the edge of the cleaning cloth is inserted for fixation. However, this method has certain drawbacks. To achieve better fixation of the cleaning cloth, the insertion holes are usually made very small to secure it tightly. This makes installation inconvenient and requires the use of sharp objects to help insert the cleaning cloth, which can easily puncture the cloth and injure the user. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] This utility model mainly addresses the shortcomings of the prior art, specifically relating to a toilet brush and toilet brush holder. It solves the technical problems in the prior art where, when a plugging hole is set on the brush head to install a cleaning cloth, the plugging hole is very small, making it inconvenient to position and install. Furthermore, when inserting the cleaning cloth, a sharp object is needed to assist in insertion, which can easily puncture the cleaning cloth and also cause accidental injury to the user.

[0006] (II) Technical Solution

[0007] In a first aspect, this utility model relates to a toilet brush, including a handle and a cleaning head disposed at one end of the handle. The handle and / or the cleaning head includes an extension portion extending outward from its periphery. The extension portion extends inward from its edge to form a clamping portion. When a cleaning cloth wraps around the cleaning head, the cleaning cloth is driven so that its edge enters the clamping portion inward from the edge of the extension portion to fix the cleaning cloth.

[0008] The advantages are that when a clamping part is provided on the extension that is recessed inward from its edge, the cleaning cloth can be inserted into the clamping part from the edge of the extension for fixation. Users can squeeze the cleaning cloth into the clamping part by hand, making installation more convenient and eliminating the need for auxiliary tools. Alternatively, when auxiliary tools are used, a flat pressing structure can be adopted, using the side of the flat plate to press the cleaning cloth into the clamping part from the edge of the extension for installation. The contact area between the side and the cleaning cloth is large, making it less likely to puncture the cleaning cloth and avoid injuring the user, resulting in a better user experience. Furthermore, because the clamping part extends inward from the edge of the extension, the span of the clamping part in the lateral direction is larger. When the cleaning cloth is inserted into the clamping part for installation, the contact area between the cleaning cloth and the clamping part is increased, resulting in greater friction. During normal cleaning operations, the cleaning cloth is less likely to detach from the clamping part, making the installation of the cleaning cloth more secure.

[0009] In one alternative embodiment, the clamping portion is closed in the initial state, and when the cleaning cloth is driven into the clamping portion, the clamping portion is opened; when the cleaning cloth enters the clamping portion, the open clamping portion returns to the closed state to fix the cleaning cloth in the clamping portion.

[0010] The advantage is that when the cleaning cloth enters the clamping part, the clamping part is open, so that the cleaning cloth can enter the interior of the clamping part. When the cleaning cloth enters the interior of the clamping part, the clamping part is closed, so that the cleaning cloth is clamped tightly through the clamping part, making the cleaning cloth more secure.

[0011] In one alternative embodiment, the extension is made of an elastic material at least at the clamping portion, so that the clamping portion, which is in a closed state, is opened after being driven to deform; and / or the clamping portion, which is in an open state, is closed under its own elastic force.

[0012] The advantage is that when the clamping part is made of an elastic material, it can automatically return to its closed position after opening, eliminating the need for the user to manually close the clamping part to tighten the cleaning cloth, making the operation simpler and more convenient.

[0013] In one alternative embodiment, the clamping portion has a deformable hole formed at the distal end of the recess inward from the edge of the extension portion, the width of the deformable hole being greater than the width of the recess.

[0014] The advantage is that by setting a deformation hole, and the width of the deformation hole is greater than the width of the recess, the clamping part will fold outward on one side of the deformation hole and on one side of the edge of the extension when it is opened, so that the clamping part can be folded outward as a whole and be in the open state.

[0015] In one alternative embodiment, the deformable hole is circular.

[0016] The advantage is that round deformable holes are easier to process and look better.

[0017] In one alternative embodiment, the cleaning head includes a guide portion corresponding to the clamping portion, adapted to move the edge of the cleaning cloth along the guide portion to engage with the clamping portion.

[0018] The advantage is that a guide section is provided in the cleaning head to guide the cleaning cloth to enter the clamping section for fixation after it covers the cleaning head.

[0019] In one alternative embodiment, the cleaning head has a centrally recessed guide portion on its side, the guide portion extending from one end of the cleaning head away from the handle toward the other end of the cleaning head near the handle;

[0020] And / or the cleaning head includes a body and bristles disposed on the body, the body having a guide portion recessed toward the center on its side, the bristles covering the portion of the body other than the guide portion, adapted to cover the bristles when the cleaning cloth is driven into the guide portion.

[0021] The advantage is that the guide is located between the bristles, so that when the edge of the cleaning cloth moves along the guide to the clamping part, part of the cleaning cloth will enter the recessed guide, making the cleaning cloth fit more tightly against the bristles. When cleaning the toilet, the cleaning cloth is less likely to fall off the cleaning head.

[0022] In one alternative embodiment, the extension is integrally formed with the cleaning head;

[0023] Alternatively, the extension may be fixed to the cleaning head via a connector;

[0024] Alternatively, it may include a fixing part that presses against the extension to the cleaning head to secure the extension.

[0025] The advantage is that, because the extension has a clamping part, fixing the extension is equivalent to fixing the position of the clamping part, so that the cleaning cloth clamped in the clamping part will not come off during the cleaning operation due to the loosening of the clamping part.

[0026] In one alternative embodiment, the fixing portion limits the extension portion between adjacent clamping portions.

[0027] The advantage is that the extension can only open or close in the clamping part to clamp the cleaning cloth.

[0028] In an alternative embodiment, a cloth removal assembly is further included, which is mounted in the handle and / or the cleaning head and is driven to move toward the cleaning head to remove the cleaning cloth covering the cleaning head.

[0029] The advantage is that after cleaning, the dirty cleaning cloth attached to the cleaning head can be removed using the cloth removal component, eliminating the need for the user to manually touch the dirty cleaning cloth, resulting in a better user experience.

[0030] In one optional embodiment, the cloth unloading assembly includes a main body, a driving part, and a pressing part. One end of the main body is connected to the driving part, and the other end is connected to the pressing part. The driving part is disposed in the handle, and the pressing part is disposed in the cleaning head and can extend from the end of the cleaning head away from the handle. When the driving part is driven to move relative to the handle, it drives the pressing part to extend from the cleaning head to press the cleaning cloth away from the cleaning head in a direction away from the handle.

[0031] In an optional embodiment, a reset member is further included, one end of which is connected to the handle and / or the cleaning head, and the other end of which is connected to the fabric unloading assembly, and is adapted to retract into the cleaning head under the action of the reset member when the pressing part extends out of the cleaning head.

[0032] The advantage is that a reset component is provided so that the unloading assembly can return to its original position after unloading the fabric, thus facilitating preparation for the next unloading operation.

[0033] Secondly, this utility model relates to a toilet brush holder, including a mounting cavity, wherein a squeezing part is provided in the mounting cavity; when the toilet brush presses against the cleaning cloth covering the top of the mounting cavity and moves toward the bottom of the mounting cavity, the squeezing part presses the cleaning cloth inward from the edge of the extension into the clamping part to fix the cleaning cloth.

[0034] The advantage is that, with the help of the toilet brush holder, users do not need to manually install the cleaning cloth on the cleaning head. Users only need to cover the top opening of the toilet brush holder with the cleaning cloth, and when the cleaning head presses the cleaning cloth into the installation cavity, the squeezing part can fix the cleaning cloth on the cleaning head. The operation is simpler and more convenient, and the user experience is better.

[0035] In one alternative embodiment, the extrusion portion extends from the inner wall of the mounting cavity toward the center of the mounting cavity;

[0036] And / or the extrusion portion extends from the bottom of the mounting cavity toward the top.

[0037] In one alternative embodiment, the squeezing portion has an arc-shaped squeezing surface at one end near the clamping portion, which is adapted to press the cleaning cloth into the clamping portion from the edge of the extension portion as the cleaning head moves toward the bottom of the mounting cavity.

[0038] The advantage is that the curved extrusion surface makes the surface where the extrusion part contacts the cleaning cloth more rounded and smooth, so that the cleaning cloth will not be punctured when it is pressed into the clamping part. Attached Figure Description

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0050] First aspect:

[0051] This utility model relates to a toilet brush 10, including a handle 11 and a cleaning head 12 disposed at one end of the handle 11. The handle 11 and / or the cleaning head 12 include an extension portion 13 extending outward from its periphery. The extension portion 13 extends inward from its edge to form a clamping portion 14. When a cleaning cloth 30 wraps around the cleaning head 12, the cleaning cloth 30 is driven so that its edge enters the clamping portion 14 from the edge of the extension portion 13 to fix the cleaning cloth 30.

[0052] When a clamping part 14 recessed inward from its edge is provided on the extension 13, the cleaning cloth 30 can be fixed by entering the clamping part 14 from the edge of the extension 13. The user can squeeze the cleaning cloth 30 into the clamping part 14 by hand, making installation more convenient and eliminating the need for auxiliary tools. Alternatively, when auxiliary tools are used, a flat extrusion structure can be adopted, using the side of the flat plate to press the cleaning cloth 30 into the clamping part 14 from the edge of the extension 13. The contact area between the side and the cleaning cloth 30 is large, making it less likely to puncture the cleaning cloth 30 and preventing injury to the user, resulting in a better user experience. Furthermore, because the clamping part 14 extends inward from the edge of the extension 13, the span of the clamping part 14 in the lateral direction is large. When the cleaning cloth 30 enters the clamping part 14 for installation, the contact area between the cleaning cloth 30 and the clamping part 14 increases, resulting in greater friction. During normal cleaning operations, the cleaning cloth 30 is less likely to detach from the clamping part 14, making the installation of the cleaning cloth 30 more secure.

[0053] The handle 11 serves as the handheld part of the toilet brush 10, allowing the user to hold the handle 11 and drive the toilet brush 10 for cleaning. The cleaning head 12 is the cleaning part of the toilet brush 10, which usually contacts the surface of the toilet to be cleaned to scrape / press and clean. Preferably, the handle 11 and the cleaning head 12 are connected in a detachable manner so that they can be manufactured and assembled separately. For example, the handle 11 and the cleaning head 12 are connected by threads, snaps, or other conventional installation methods, which will not be described in detail here.

[0054] The extension portion 13 is used to form the substrate of the clamping portion 14. That is, the clamping portion 14 needs to be provided on the extension portion 13. The extension portion 13 can be provided on the handle 11, specifically at the end of the handle 11 near the cleaning head 12, so that the cleaning cloth 30 covering the cleaning head 12 can be connected to the clamping portion 14 on the extension portion 13. For example, it can be formed by extending outward from the surface of the handle 11. The extension portion 13 can be integrally formed with the handle 11, or it can be separately formed with the handle 11 and then assembled together. The extension portion 13 can also be provided on the cleaning head 12, specifically at the end of the cleaning head 12 near the handle 11, so that the cleaning cloth 30 covering the cleaning head 12 can be connected to the clamping portion 14 on the extension portion 13. For example, it can be formed by extending outward from the surface of the cleaning head 12. The extension portion 13 can be integrally formed with the cleaning head 12, or it can be separately formed with the cleaning head 12 and then assembled together. It is understood that the extension portion 13 can be provided on both the cleaning head 12 and the handle 11 to enhance the firmness of the cleaning cloth 30 installation.

[0055] In this example, the preferred extension 13 is a sheet-like structure. A through hole is located in the center of the extension 13 for the connection between the cleaning head 12 and the handle 11, or for the handle 11 to pass through. Several clamping portions 14 are provided around the periphery of the extension 13. Specifically, the periphery of the extension 13 is recessed inward to form several clamping portions 14. Preferably, the extension 13 is rectangular, with clamping portions 14 on all four sides, allowing all four sides of the cleaning cloth 30 to be clamped, resulting in better wrapping of the cleaning head 12 by the cleaning cloth 30. It is understood that the extension 13 can also be polygonal; correspondingly, to improve clamping efficiency, clamping portions 14 are provided on each side. When the extension 13 is circular, the clamping portions 14 can be evenly distributed around the edge of the extension 13. Preferably, the included angle between adjacent clamping portions 14 is equal.

[0056] The extension 13 is recessed inward from its edge to form a clamping part 14, so that the clamping part 14 forms a slit structure with one end open. The cleaning cloth 30 can enter the clamping part 14 along the opening for fixation. In this example, the slit of the clamping part 14 is preferably a straight slit to facilitate better entry of the cleaning cloth 30. It can be understood that the slit of the clamping part 14 can also be designed as a continuous bending shape or an arc shape, as long as the clamping part 14 can be fixed.

[0057] The cleaning cloth 30 is wrapped around the cleaning head 12. Preferably, the center of the cleaning cloth 30 corresponds to the end of the cleaning head 12 away from the handle 11. Then, the periphery of the cleaning cloth 30 is rotated towards the handle 11 to cover the cleaning head 12, so that the cleaning cloth 30 wraps the cleaning head 12 and the edge of the cleaning cloth 30 is fixed in the clamping part 14. It can be understood that the cleaning cloth 30 can also be designed as a sleeve shape that matches the opening of one end of the cleaning head 12. In use, the cleaning head 12 is inserted into the sleeve along the opening. The cleaning cloth 30 has an extension section at the opening, so that the extension section of the cleaning cloth 30 can be clamped in the clamping part 14 to fix the cleaning cloth 30.

[0058] The edge of the cleaning cloth 30 enters the clamping part 14. Specifically, the end of the cleaning head 12 away from the handle 11 is pressed against the center of the cleaning cloth 30. The user can manually pinch the edge of the clamping part 14 and turn the edge of the cleaning cloth 30 to the extension part 13, and then enter the clamping part 14 from the edge of the extension part 13. Alternatively, the edge of the cleaning cloth 30 can be placed at the clamping part 14, and an auxiliary tool, such as a flat plate, can be used to press the cleaning cloth 30 into the clamping part 14 for fixation. The auxiliary tool can also be a thin rod-like structure in the shape of a wire, and the side of the rod can be used to press the cleaning cloth 30 into the clamping part 14 for fixation. As long as the end of the rod is not used, the cleaning cloth 30 will not be punctured.

[0059] In one optional embodiment, the clamping portion 14 is initially closed. When the cleaning cloth 30 is driven into the clamping portion 14, the clamping portion 14 opens. When the cleaning cloth 30 enters the clamping portion 14, the open clamping portion 14 returns to its closed position to secure the cleaning cloth 30 within the clamping portion 14. The clamping portion 14 is open when the cleaning cloth 30 enters, allowing it to enter the interior of the clamping portion 14. When the cleaning cloth 30 enters the interior of the clamping portion 14, the clamping portion 14 closes to clamp the cleaning cloth 30 securely, resulting in a more secure fixation of the cleaning cloth 30.

[0060] Initially, the toilet brush 10 is not covered by the cleaning cloth 30. When the cleaning cloth 30 enters the clamping part 14, due to its thickness, it squeezes the clamping part 14 as it enters along the edge of the extension 13, causing the clamping part 14 to be in an open state. When the cleaning cloth 30 is inside the clamping part 14 and is no longer being driven, the clamping part 14, being made of flexible material, will gradually return from its open state to a closed state, clamping the cleaning cloth 30. It is understandable that when an auxiliary tool is used to squeeze the cleaning cloth 30 into the clamping part... When the auxiliary tool is in position 14, it will squeeze the clamping part 14 due to the thickness of the auxiliary tool, thus making the clamping part 14 open. When the cleaning cloth 30 enters the clamping part 14, the auxiliary tool is removed. The flexible material of the cleaning cloth 30 is not enough to maintain the squeezing of the clamping part 14. The clamping part 14 will gradually return from being open to being closed and clamp the cleaning cloth 30. In this example, the preferred opening direction of the clamping part 14 is that the side of the extension 13 at the clamping part 14 rotates in one direction, that is, the extension 13 bulges in the clamping part 14 in a specified direction to make the gap of the clamping part 14 larger.

[0061] Understandably, the gap of the clamping part 14 has deformable protrusions on both sides. In the initial state, the protrusions on both sides abut and cooperate to close the gap. When the protrusions are squeezed and deformed along the extension direction of the plate surface of the extension part 13, the protrusions on both sides will open to allow the cleaning cloth 30 to enter.

[0062] Understandably, the clamping part 14 is a clamping piece that can slide along the extension direction of the extension part 13, and clamping pieces are provided on both sides of the gap. In the initial state, the two clamping pieces abut against each other to close the gap. When the two clamping pieces are driven to slide, the gap is opened so that the cleaning cloth 30 can enter.

[0063] In one optional embodiment, the extension 13 is made of an elastic material at least at the clamping portion 14, so that the clamping portion 14, which is closed, opens after being deformed by a drive; and / or the clamping portion 14, which is open, closes under its own elastic force. When the material of the clamping portion 14 is made of an elastic material, such as soft rubber or rubber, which can deform under force, the clamping portion 14 can automatically return to the closed position after opening, without requiring the user to manually close the clamping portion 14 to clamp the cleaning cloth 30, making the operation simpler and more convenient. In this example, the extension 13 can preferably be made of an elastic material as a whole, and the clamping portion 14 is a number of slits opened on the periphery of the extension 13, which facilitates processing and assembly.

[0064] Understandably, the extension 13 is made of a rigid material, while the clamping part 14 is made of an elastic material. The extension 13 is provided with a mounting groove for mounting the clamping part 14. The clamping part 14 is installed in the mounting groove. The two can be connected by snap-fit ​​or by coating.

[0065] Understandably, both the extension 13 and the clamping part 14 are made of rigid materials, and the extension 13 and the clamping part 14 are connected by a pivot. The extension 13 and the clamping part 14 are reset by elastic elements such as springs or tension springs. The specific structural details are not described here. This structure is similar to a double door structure.

[0066] In one optional embodiment, the clamping portion 14 has a deformation hole 15 formed at the distal end of the inward recess from the edge of the extension portion 13. The width of the deformation hole 15 is greater than the width of the recess. By providing the deformation hole 15 and the width of the deformation hole 15 being greater than the width of the recess, when the clamping portion 14 is opened, the clamping portion 14 is turned outward on one side of the deformation hole 15 and on one side of the edge of the extension portion 13, so that the clamping portion 14 can be turned outward as a whole and be in an open state. In this example, the deformation hole 15 is preferably circular, as a circular deformation hole 15 is easier to process and also more aesthetically pleasing.

[0067] In one optional embodiment, the cleaning head 12 includes a guide portion 16 corresponding to the clamping portion 14, adapted to allow the edge of the cleaning cloth 30 to move along the guide portion 16 to engage with the clamping portion 14. The guide portion 16 is provided in the cleaning head 12 to guide the cleaning cloth 30 to cover the cleaning head 12 and enter the clamping portion 14 for fixation.

[0068] The cleaning head 12 has a guide portion 16 recessed towards the center on its side. The guide portion 16 extends from the end of the cleaning head 12 away from the handle 11 toward the end of the cleaning head 12 near the handle 11. The recessed guide portion 16 facilitates the movement of the cleaning cloth 30 along the recess, so that the recess forms a movement path. On the other hand, it can also insert part of the cleaning cloth 30 into the recessed guide portion 16, so as to more securely and tightly install the cleaning cloth 30 on the cleaning head 12.

[0069] In another embodiment, the cleaning head 12 includes a body 182 and bristles 17 disposed on the body 182. The body 182 has a guide portion 16 recessed towards the center on its side. The bristles 17 cover the portion of the body 182 other than the guide portion 16, adapted to cover the bristles 17 when the cleaning cloth 30 is driven into the guide portion 16. The guide portion 16 is disposed between the bristles 17 such that when the edge of the cleaning cloth 30 moves along the guide portion 16 to the clamping portion 14, a portion of the cleaning cloth 30 enters the recessed guide portion 16, making the cleaning cloth 30 more closely adhere to the bristles 17. When cleaning the toilet, the cleaning cloth 30 is less likely to fall off the cleaning head 12. In this example, the number of guide portions 16 preferably matches the number of clamping portions 14.

[0070] In one optional embodiment, the extension 13 is integrally formed with the cleaning head 12. In this example, the extension 13 and the cleaning head 12 are preferably made of the same material. They can be integrally formed by injection molding. For example, both are deformable materials such as rubber, soft rubber, TPE, and TPU, so that the clamping part 14 can open to allow the cleaning cloth 30 to enter. At the same time, the cleaning head 12 covered with the cleaning cloth 30 can be bent under force to clean some hard corners of the toilet.

[0071] Understandably, the extension 13 is fixed to the cleaning head 12 by a connector. The connector can be a fastener, Velcro, snap fastener, or other fixing connector. The extension 13 and the cleaning head 12 can be made of the same material or different materials.

[0072] Understandably, the toilet brush 10 also includes a fixing part (not shown in the figure), which presses against the extension part 13 onto the cleaning head 12 to fix the extension part 13; the fixing part is integrally formed with the handle 11, and the cleaning head 12 passes through the extension part 13 and connects to the handle 11 to fix the extension part 13 between the cleaning head 12 and the fixing part. The fixing part is provided to fix the extension part 13 because the extension part 13 has a clamping part 14. Fixing the extension part 13 is equivalent to fixing the position of the clamping part 14, so that the cleaning cloth 30 clamped in the clamping part 14 will not fall off during the cleaning operation due to the loosening of the clamping part 14.

[0073] The fixing part limits the extension 13 between adjacent clamping parts 14. The fixing part is used to fix the extension 13, so its shape matches the shape of the extension 13. Since the clamping part 14 needs to hold the cleaning cloth 30, when the fixing part fixes the extension 13 to the cleaning head 12, a clearance needs to be left at the position of the clamping part 14. For example, when clamping parts 14 are provided on opposite sides of the extension 13, the fixing part can be set in an "I" shape, so that the fixing part fixes the extension 13 except for the portion of the clamping part 14, so that the extension 13 can only open or close at the portion of the clamping part 14 to clamp the cleaning cloth 30. This better enhances the fixing firmness of the extension 13, thereby enhancing the installation firmness of the cleaning cloth 30.

[0074] In another embodiment, the fixing part and the handle 11 are separately formed, and the handle 11 passes through the fixing part and is connected to the cleaning head 12 to fix the extension 13 between the cleaning head 12 and the fixing part, which facilitates production and processing, and also facilitates the replacement of parts as needed.

[0075] In an optional embodiment, a cloth removal assembly 18 is further included. The cloth removal assembly 18 is installed in the handle 11 and / or the cleaning head 12. The cloth removal assembly 18 is driven to move toward the cleaning head 12 to remove the cleaning cloth 30 covering the cleaning head 12. After cleaning, the dirty cleaning cloth 30 installed on the cleaning head 12 is removed by the cloth removal assembly 18, eliminating the need for the user to manually touch the dirty cleaning cloth 30, thus providing a better user experience. In this example, the driving end of the cloth removal assembly 18 is preferably installed in the handle 11, away from the cleaning head 12, to avoid soiling the user's hands, while the cloth removal end of the cloth removal assembly 18 is installed in the cleaning head 12 to facilitate the removal of the cleaning cloth 30 covering the cleaning head 12.

[0076] Understandably, the cloth removal assembly 18 can also be installed in the handle 11 and can move relative to the handle 11 to remove the cleaning cloth 30 covering the cleaning head 12. The removal method can be such as scraping or pushing off the cleaning cloth 30. For example, a sleeve (not shown in the figure) that can slide relative to the handle 11 can be provided in the handle 11. A scraper is provided on the side of the sleeve near the cleaning head 12. The scraper can scrape off the cleaning cloth 30 covering the cleaning head 12 as the sleeve moves relative to the handle 11.

[0077] Understandably, the cloth removal assembly 18 can also be set in the cleaning head 12. For example, a switch can be set in the cleaning head 12, and the switch is connected to the push plate (not shown in the figure). When the switch is activated, the push plate will move toward the cleaning head 12 away from the handle 11 to remove the cleaning cloth 30. The switch can be connected to the push plate by a snap-fit ​​method, and the pushing force of the push plate can be achieved by a spring.

[0078] In one optional embodiment, the cloth unloading assembly 18 includes a main body 182, a driving part 181, and a pressing part 183. One end of the main body 182 is connected to the driving part 181, and the other end is connected to the pressing part 183. The driving part 181 is disposed in the handle 11, and the pressing part 183 is disposed in the cleaning head 12 and can extend from the end of the cleaning head 12 away from the handle 11. When the driving part 181 is driven to move relative to the handle 11, it drives the pressing part 183 to extend from the cleaning head 12 to press the cleaning cloth 30 away from the cleaning head 12. The main body 182 is used to connect the driving part 181 and the pressing part 183 to transmit the drive from the driving part 181 to the pressing part 183. The driving end is a push knob. The side wall of the handle 11 is provided with a receiving groove for pushing. The knob can slide in the receiving groove. The handle 11 has a hollow structure inside, and the main body 182 is installed in the hollow structure. The cleaning head 12 has a receiving cavity inside that corresponds to the hollow structure. The end of the receiving cavity away from the handle 11 forms an opening that communicates with the outside. The pressing part 183 is located in the receiving cavity and can move in the receiving cavity. It can extend or retract from the opening. When the push knob is pushed in the direction of the cleaning head 12, the push knob drives the main body 182 to move, thereby driving the pressing part 183 to move out of the receiving cavity to push the cleaning cloth 30 to be removed from the cleaning head 12. In order to avoid the pressing part 183 puncturing the cleaning cloth 30, the pressing part 183 can be set as a flat surface or an arc surface. The width of the pressing part 183 can even be set to be greater than the width of the main body 182 to increase the contact area between the pressing part 183 and the cleaning cloth 30.

[0079] Understandably, the main body 182 and the pressing part 183 can be configured as an integral structure. After the main body 182 passes through the hollow structure of the handle 11, it enters the receiving cavity. When the push knob moves the main body 182, the end of the main body 182 away from the push knob extends out of the receiving cavity to push the cleaning cloth 30 to be removed from the cleaning head 12.

[0080] In an optional embodiment, a reset member 184 is further included. One end of the reset member 184 is connected to the handle 11 and / or the cleaning head 12, and the other end is connected to the fabric unloading assembly 18. It is adapted to retract into the cleaning head 12 under the action of the reset member 184 when the pressing part 183 extends out of the cleaning head 12. The reset member 184 is provided so that the fabric unloading assembly 18 can return to its original position after fabric unloading, thereby facilitating preparation for the next fabric unloading operation. In this example, the preferred reset member 184 is a spring, which can be sleeved on the main body. Around the periphery of handle 11, a fixed retaining ring is provided in the hollow cavity of handle 11. One end of the spring is connected to the retaining ring, and the other end is connected to the drive unit 181, so that when the drive unit 181 moves relative to handle 11, the spring is in a compressed state. At this time, the pressing part 183 extends out of the cleaning head 12 to remove the cleaning cloth 30. After the removal is completed, when the drive of the drive unit 181 is released, the drive unit 181 will move away from the cleaning head 12 as the spring is released, thereby driving the pressing part 183 to retract into the cleaning head 12, in preparation for the next cloth removal operation.

[0081] Understandably, the reset element 184 can also be a tension spring, with both ends of the tension spring connected to the retaining ring of the handle 11 and the drive unit 181, respectively, so that when the drive unit 181 moves toward the cleaning head 12, the tension spring is in a stretched state, and when the drive unit 181 moves away from the cleaning head 12, the tension spring is in a relaxed state.

[0082] The second aspect:

[0083] This utility model relates to a toilet brush holder 10, including a mounting cavity 21, wherein a squeezing part 22 is provided in the mounting cavity 21; when the toilet brush 10 presses against the cleaning cloth 30 covering the top of the mounting cavity 21 and moves toward the bottom of the mounting cavity 21, the squeezing part 22 presses the cleaning cloth 30 inward from the edge of the extension part 13 into the clamping part 14 to fix the cleaning cloth 30.

[0084] With the toilet brush seat 10 in use, users no longer need to manually install the cleaning cloth 30 on the cleaning head 12. Users only need to cover the top opening of the toilet brush seat 10 with the cleaning cloth 30. When the cleaning head 12 presses the cleaning cloth 30 into the installation cavity 21, the squeezing part 22 can fix the cleaning cloth 30 on the cleaning head 12. The operation is simpler and more convenient, and the user experience is better.

[0085] The toilet brush 10 seat is used to assist in the installation of the cleaning cloth 30 with the toilet brush 10. The mounting cavity 21 is used to accommodate the cleaning head 12 of the toilet brush 10. A squeezing part 22 is provided in the mounting cavity 21, so that as the cleaning head 12 gradually moves towards the bottom of the mounting cavity 21, the squeezing part 22 will cooperate with the clamping part 14 to clamp the cleaning cloth 30. Preferably, the number and position of the squeezing part 22 and the clamping part 14 correspond.

[0086] In one alternative embodiment, the extrusion portion 22 extends from the inner wall of the mounting cavity 21 toward the center of the mounting cavity 21. In this example, the extrusion portion 22 is preferably a plate-like structure. Furthermore, the extrusion portion 22 extends from the bottom to the top of the mounting cavity 21, resulting in higher strength. It is understood that the extrusion portion 22 is only located on the top inner wall of the mounting cavity 21.

[0087] In another embodiment, the compression portion 22 extends from the bottom of the mounting cavity 21 toward the top.

[0088] In one alternative embodiment, the squeezing part 22 has an arc-shaped squeezing surface 221 at one end near the clamping part 14. This arc-shaped squeezing surface 221 is adapted to press the cleaning cloth 30 into the clamping part 14 from the edge of the extension part 13 when the cleaning head 12 moves toward the bottom of the mounting cavity 21. The arc-shaped squeezing surface 221 makes the surface of the squeezing part 22 and the cleaning cloth 30 more rounded and gentle, so that the cleaning cloth 30 will not be punctured when it is pressed into the clamping part 14.

[0089] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
