Description

Technical Field

[0001] This utility model relates to the field of daily cleaning tools, and in particular to toilet brushes. Background Technology

[0002] Toilet brushes are commonly used tools for daily toilet cleaning. A toilet brush typically consists of a brush head and a handle, which are detachably connected for easy replacement or cleaning. Currently, users must hold the brush head directly when connecting or disconnecting it. This method is not only inconvenient but also increases the risk of cross-infection due to contact with bacteria and dirt, posing a potential threat to the user's health. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a toilet brush that does not contact the brush head and is easy to install and remove.

[0004] The technical solution adopted in this utility model is the toilet brush, which includes a brush head and a brush handle detachably connected to the brush head. The brush handle includes a lever, which is connected to a connecting device for detachable connection with the brush head. The brush head has a cavity and an opening into which the connecting device can extend. The connecting device includes a movable part that can increase or decrease the radial dimension of the brush handle, and a rotating part rotatably connected to a guide head. The movable part is slidably connected to the lever along the axial direction of the brush handle. The outer diameter of the guide head gradually increases from the end away from the brush handle to the end closer to the brush handle, and the width of the guide head is smaller than the radial dimension of the connecting device when it increases. The two rotating parts are symmetrically distributed about the axial line of the brush handle, and the ends of the two rotating parts near the guide head are rotatably connected to the guide head. Each of the two rotating parts is provided with a sliding groove; the movable part has two protrusions that fall into the sliding groove and are movably connected to the sliding groove, and the movable parts are connected to push the push part of the brush head; the sliding groove extends from the handle toward the guide head in an axial line from the axial line close to the brush handle to the axial line away from the brush handle; during the process of connecting the brush head and the brush handle, the guide head first enters the cavity of the brush head, and after the opening edge of the brush head abuts against the push part, the guide head further enters the brush head, and the brush head can push the movable part to move away from the guide head and drive the two rotating parts to move away from each other, so that the radial dimension of the connecting device increases and thus it is combined with the brush head; during the process of separating the brush head from the brush handle, the movable part moves toward the guide head, and the movable part drives the two rotating parts to move closer together, so that the radial dimension of the connecting device decreases and the push part pushes the brush head away from the connecting device.

[0005] The brush head described in this invention is made of a vegetable scraper material.

[0006] The slide of this utility model has an extension section in which the movable part can continue to move in the direction of the guide head after the two rotating parts are close together.

[0007] The present invention describes a push rod that is slidably connected to the handle and moves along the axial direction of the handle. The lower end of the push rod is connected to the movable part, and the upper end of the push rod is connected to the operating part. A locking mechanism for locking the operating part is provided between the handle and the operating part. When the brush head is connected to the brush handle, the locking mechanism keeps the operating part fixed.

[0008] The locking mechanism of this utility model includes a convex part and a concave part, which are respectively provided on the handle and the operating part. The convex part and the concave part are in an interference fit, and the convex part remains fixedly engaged when it is in the concave part.

[0009] The present invention describes a push rod that is slidably connected to the handle and moves along the axial direction of the handle. The lower end of the push rod is connected to the movable part, and the upper end of the push rod is connected to the operating part. A locking mechanism for locking the operating part is provided between the push rod and the handle. When the brush head is connected to the brush handle, the locking mechanism keeps the operating part fixed.

[0010] The locking mechanism of this utility model includes a convex part and a concave part, which are respectively provided on the push rod and the handle. The convex part and the concave part are in an interference fit, and the convex part remains fixedly engaged when it is in the concave part.

[0011] The present invention also includes a brush holder for storing brush heads. The brush holder includes a hollow cylindrical body with space for vertically stacking brush heads. The cylindrical body has openings on the side and top, and a cover adjacent to the top opening is rotatably connected to the cylindrical body.

[0012] The yield strength of the brush head described in this invention is greater than the weight of the moving parts.

[0013] The yield strength of the brush head described in this invention is greater than the sum of the weights of the moving part, the push rod, and the operating part.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention allows the user to operate the brush head by holding the handle. The guide head first enters the cavity of the brush head, and after the opening edge of the brush head contacts the push part, the guide head further enters the brush head. The brush head then pushes the movable part away from the guide head, causing the two rotating parts to move away from each other, increasing the radial dimension of the connecting device and thus connecting it to the brush head. During the process of detaching the brush head from the handle, the movable part moves closer to the guide head, causing the two rotating parts to move closer together, reducing the radial dimension of the connecting device, and the push part pushes the brush head away from the connecting device. Throughout this process, the user operates the brush head by holding the handle, avoiding direct contact with the brush head, effectively reducing the risk of contact with bacteria and dirt, and improving hygiene and safety during use. Furthermore, the connecting device makes connecting and disconnecting the brush head more convenient, improving the user experience. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and through embodiments.

[0021] like Figures 1 to 5As shown, the toilet brush of this embodiment includes a brush head 1 and a brush handle 2 detachably connected to the brush head 1. The brush handle 2 includes a handle 3, which is connected to a connecting device 4 for detachable connection to the brush head 1. The brush head 1 has a cavity 11 and an opening into which the connecting device 4 can extend. The connecting device 4 includes a movable part 41 that allows the brush handle 2 to increase or decrease in radial dimension, and a rotating part 43 that is rotatably connected to a guide head 42. The movable part 41 is slidably connected to the handle 3 along the axial direction of the brush handle 2. The guide head 42 is located away from the brush head 1. One end of the handle 2 gradually increases in outer diameter towards the end closer to the brush handle 2. The width of the guide head 42 is smaller than the radial dimension of the connecting device 4 when it increases in size. The two rotating parts 43 are symmetrically distributed about the axial line of the brush handle 2. The ends of the two rotating parts 43 near the guide head 42 are rotatably connected to the guide head 42. The two rotating parts 43 are each provided with a sliding groove 431. The movable part 41 has two protrusions 411 that fall into the sliding groove 431 and are movably connected to the sliding groove 431. The movable part 41 can push against the push part 412 of the brush head 1. The groove 431 extends from the handle 3 toward the guide head 42 in an axial direction from the axial line near the brush handle 2 toward the axial line away from the brush handle 2. During the connection between the brush head 1 and the brush handle 2, the guide head 42 first enters the cavity 11 of the brush head 1. After the opening edge of the brush head 1 abuts against the push part 412, the guide head 42 further enters the brush head 1. The brush head 1 can push the movable part 41 to move away from the guide head 42 and drive the two rotating parts 43 to move away from each other, so that the radial dimension of the connecting device 4 increases and thus it is combined with the brush head 1. During the disengagement of the brush head 1 from the brush handle 2, the movable part 431... The movable part 41 moves towards the guide head 42. The movable part 41 drives the two rotating parts 43 to move closer together, making the radial dimension of the connecting device 4 smaller and the pushing part 412 pushes the brush head 1 away from the connecting device 4. In this embodiment, during the connection and disconnection process of the brush head 1 and the brush handle 2, the user holds the brush handle 2 to operate, avoiding direct contact with the brush head 1, thereby effectively reducing the risk of the user coming into contact with bacteria and dirt, and improving the hygiene and safety during use; and the setting of the connecting device 4 makes the connection and disconnection of the brush head 1 more convenient, improving the user experience.

[0022] Preferably, the brush head 1 is made of a scouring pad material; the surface of the scouring pad material has multiple protrusions, which makes the cleaning effect more significant and can effectively remove stubborn dirt.

[0023] Preferably, the slide groove 431 has an extension section 432 that allows the movable member 41 to continue moving toward the guide head 42 after the two rotating members 43 approach each other. The extension section 432 is provided so that during the process of separating the brush head 1 from the brush handle 2, after the two rotating members 43 have approached each other to a certain extent, the movable member 41 still has a certain amount of room to move toward the guide head 42, thereby more smoothly completing the pushing action of the pusher 412 on the brush head 1.

[0024] Example 1: The handle 3 is slidably connected to a push rod 5 for driving the movable part 41. The push rod 5 is slidably connected to the handle 3 and moves along the axial direction of the handle 3. The lower end of the push rod 5 is connected to the movable part 41, and the upper end of the push rod 5 is connected to the operating part 6. The handle 3 and the operating part 6 have a locking mechanism 7 for locking the operating part 6. When the brush head 1 is connected to the brush handle 2, the locking mechanism 7 keeps the operating part 6 fixed. The locking mechanism 7 includes a protrusion 71 and a recess 72, which are respectively provided on the handle 3 and the operating part 6. The protrusion 71 and the recess 72 are interference fit. When the protrusion 71 is in the recess 72, it is fixedly connected. In this embodiment, the protrusion 71 and the concave part 72 are interference-fitted. When the protrusion 71 is in the concave part 72, it remains fixedly engaged, thereby locking the operating part 6 by the locking mechanism 7. This locks the push rod 5, ultimately connecting the brush head 1 to the brush handle 2. When the brush head 1 needs to be replaced or cleaned, the locking mechanism 7 is first released from the operating part 6. Specifically, the interference fit force between the protrusion 71 and the concave part 72 is overcome, allowing the protrusion 71 to disengage from the concave part 72. At this time, the operating part 6 can move along the axial direction of the handle 3. By pushing the operating part 6, the push rod 5 moves along the axial direction of the handle 3. The push rod 5 drives the movable part 41 to move closer to the guide head 42. The movable part 41 drives the two rotating parts 43 to move closer together, making the radial dimension of the connecting device 4 smaller and the push part 412 pushes the brush head 1 away from the connecting device 4, thus completing the disengagement operation of the brush head 1 from the brush handle 2. This design makes the connection and disengagement operation of the brush head 1 from the brush handle 2 more convenient and labor-saving, improving the overall ease of use of the cleaning tool.

[0025] Example 2: The handle 3 is slidably connected to a push rod 5 for driving the movable part 41. The push rod 5 is slidably connected to the handle 3 and moves along the axial direction of the handle 3. The lower end of the push rod 5 is connected to the movable part 41, and the upper end of the push rod 5 is connected to the operating part 6. There is a locking mechanism 7 between the push rod 5 and the handle 3 for locking the operating part 6. When the brush head 1 is connected to the brush handle 2, the locking mechanism 7 keeps the operating part 6 fixed. The locking mechanism 7 includes a protrusion 71 and a recess 72, which are respectively provided on the push rod 5 and the handle 3. The protrusion 71 and the recess 72 are in an interference fit. When the protrusion 71 is in the recess 72, it is fixedly connected. The operation method is similar to that of Example 1, except that the protrusion 71 and the recess 72 in the locking mechanism 7 are respectively provided on the push rod 5 and the handle 3. Similarly, the locking mechanism 7 locks the operating part 6 to realize the connection between the brush head 1 and the brush handle 2. The brush head 1 is disengaged from the brush handle 2 by pushing the operating part 6 after unlocking.

[0026] The device also includes a brush holder 8 for storing the brush head 1. The brush holder 8 includes a hollow cylindrical body 81 with space for vertically stacking the brush head 1. The cylindrical body 81 has openings on the side and top, and a cover 82 that is rotatably connected to the cylindrical body 81 is adjacent to the top opening. The function of the brush holder 8 is to store the brush head 1 and provide operating space for connecting the brush head 1 to the brush handle 2. The cover 82 can prevent dust and other impurities from falling into the inside of the cylindrical body 81 and keep the brush head 1 clean and hygienic.

[0027] In this embodiment, the yield strength of the brush head 1 is greater than the weight of the movable part 41. Since the brush head 1 has a yield strength greater than the weight of the movable part 41, even if the movable part 41 applies a certain force to the brush head 1, the brush head 1 will not easily undergo plastic deformation, thereby ensuring the stability and durability of the brush head 1 during use.

[0028] In this embodiment, the yield strength of the brush head 1 is greater than the sum of the weights of the moving part 41, the push rod 5, and the operating part 6; the brush head 1 can withstand this force without plastic deformation, thus ensuring the stability and durability of the brush head 1 during use.
