Description

A disposable toilet brush and its brush head Technical Field

[0001] This utility model relates to the field of cleaning tool technology, and in particular to a disposable toilet brush and its brush head. Background Technology

[0002] To keep toilets clean, most people choose to use toilet brushes. However, after prolonged use, a lot of dirt accumulates inside the toilet bowl, requiring cleaning with a toilet brush. Currently, toilet brush heads on the market are also prone to harboring bacteria and grime, making them inconvenient to clean. With prolonged use, the bristles are prone to falling off, requiring the entire toilet brush to be thrown away, resulting in a waste of resources.

[0003] According to the patent announcement number CN220631967U on the Chinese Patent Website, a toilet brush cleaning tool set requires the toilet brush to be parallel to the outlet of the brush head storage container when changing the brush head. Since toilet cleaning tools are usually located close to the toilet and fixed near the ground, the user needs to make the toilet brush perpendicular to the toilet when changing the brush head. This requires the user to bend over significantly to change the brush head, and the exposed toilet brush also occupies a certain amount of space.

[0004] To address the above problems, this utility model proposes a disposable toilet brush and its brush head. Utility Model Content

[0005] Based on the existing problems of toilet cleaning technology, this utility model proposes a disposable toilet brush and its brush head.

[0006] On one hand, this utility model proposes a disposable toilet brush, including a handle and a cleaning head placement box. The cleaning head placement box includes an outer cover fixed to a wall, with an outer box at one end of the outer cover. The bottom end of the outer box is rotatably hinged to the bottom end of the outer cover. A groove adapted to the surface of the handle is opened on one side of the outer box. The groove surface array has limiting grooves embedded in the outer box. A limiting block is fixedly connected to the upper end of the groove. A non-woven cleaning head is movably engaged between multiple limiting grooves in the cavity on the other side of the outer box. The handle is movably hooked to the surface of the limiting block.

[0007] Preferably, the maximum opening angle between the outer box and the outer cover is 60-80 degrees.

[0008] Preferably, the handle includes a handle bar, the upper end of which is provided with a handle bar cover, a push rod is slidably connected to the inner wall of the lower end of the handle bar, a groove is formed on the outer surface of the lower end of the handle bar, a push button is slidably connected to the groove surface, and one side of the push button extends into the interior of the handle bar and is movably engaged with the rod body of the push rod.

[0009] Preferably, the lower end of the handle is further provided with a movable buckle, and the lower end of the handle is fixedly connected to a fabric clamping outer rod by the movable buckle. An upper clamping tooth is fixedly connected to the outer surface of the lower end of the fabric clamping outer rod, and a fabric clamping inner rod is slidably connected to the inner wall of the fabric clamping outer rod. A lower clamping tooth is fixedly connected to the lower end of the fabric clamping inner rod, and the upper end of the fabric clamping inner rod is tightly fitted to the lower end of the push rod.

[0010] Preferably, a spring baffle is fixedly connected at the middle position of the groove surface. The lower end of the spring baffle is a first cross post protruding upwards. A spring is fixedly sleeved on the surface of the first cross post. A second cross post, identical to the lower end of the spring baffle, is provided on the side of the inner rod of the fabric clamp near the spring baffle. The lower end of the second cross post is fixedly sleeved with the upper end of the spring, and the upper end of the second cross post is movably engaged with the upper end of the spring baffle.

[0011] On the other hand, this utility model proposes a brush head, which is used in a disposable toilet brush as described in claims 1-5, the brush head comprising,

[0012] Multiple layers of material sheets fixed at the top to each other in a stacked manner;

[0013] The top fixing point is the compression area;

[0014] Each layer is formed from at least one sheet of material, which is folded along a fold line to form a loop, and the fold line is located away from the compression area;

[0015] Each of the material sheets forms a ring with two parallel cuts, the cuts extending from away from the compression area;

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example 1

[0035] Referring to Figures 1-11, a disposable toilet brush includes a handle 1 and a cleaning head placement box 2. The cleaning head placement box 2 includes an outer cover 21 fixed to the wall. One end of the outer cover 21 is provided with an outer box 22. The bottom end of the outer box 22 is rotatably hinged to the bottom end of the outer cover 21. A groove 24 adapted to the surface of the handle 1 is provided on one side of the outer box 22. The groove surface of the groove 24 is provided with limiting grooves 26 embedded in the outer box 22. A limiting block 25 is fixedly connected to the upper end of the groove 24. A non-woven cleaning head 23 is movably engaged between multiple limiting grooves 26 in the cavity on the other side of the outer box 22. The handle 11 is movably hooked to the surface of the limiting block 25.

[0036] By setting up the above structure, the operating lever 1 can be opened without touching the cleaning head placement box 2, thereby enabling the replacement of the non-woven fabric cleaning head 23 and avoiding user contact with bacteria, thus preventing harm to human health.

[0037] In this embodiment, the handle 1 includes a handle 11, with a handle cover 12 at the upper end of the handle 11. A push rod 13 is slidably connected to the inner wall of the lower end of the handle 11. A groove is formed on the outer surface of the lower end of the handle 11, and a push button 14 is slidably connected to the groove surface. One side of the push button 14 extends into the interior of the handle 11 and is movably engaged with the rod body of the push rod 13. In this embodiment, a movable buckle is also provided at the lower end of the handle 11. A fabric clamping outer rod 15 is fixedly engaged at the lower end of the handle 11 through the movable buckle. An upper locking tooth 16 is fixedly connected to the outer surface of the lower end of the fabric clamping outer rod 15. A fabric clamping inner rod 17 is slidably connected to the inner wall of the fabric clamping outer rod 15. A lower locking tooth 18 is fixedly connected to the lower end of the fabric clamping inner rod 17. The lower end of the push rod 13 at the upper end of the fabric clamping inner rod 17 is tightly fitted.

[0038] Specifically, by setting up the above structure, when the user holds the upper end of the handle 1, he pushes the outer box 22 downward. The outer box 22 opens at an angle of 60-80 degrees with the outer cover 21, which makes it convenient for the user to push the inner rod 17 of the fabric clamping device downward through the push button 14, thereby releasing the fixing effect between the upper clamping tooth 16 and the lower clamping tooth 18 on the non-woven fabric cleaning head 23, and realizing contactless replacement of the non-woven fabric cleaning head 23.

[0039] In this embodiment, the maximum opening angle between the outer box 22 and the outer cover 21 is 60-80 degrees;

[0040] Specifically, the design of the above structure allows the handle 1 to remove and replace the non-woven cleaning head 23, while ensuring that the outer box 22 avoids excessive weight on the outer cover 21 due to an excessive opening angle, which would prevent the cleaning head placement box 2 from being used normally. The 60-80 degree opening angle also makes it easier for users to reduce the bending over when replacing the brush head, thus increasing the effectiveness of use.

[0041] In this embodiment, a spring baffle 19 is fixedly connected to the middle position of the groove surface of the groove 24. The lower end of the spring baffle 19 is a first cross post protruding upward. A spring 110 is fixedly sleeved on the surface of the first cross post. The inner rod 17 of the fabric clamp is provided with a second cross post that is the same as the lower end of the spring baffle 19 on the side near the spring baffle 19. The lower end of the second cross post is fixedly sleeved with the upper end of the spring 110, and the upper end of the second cross post is movably engaged with the upper end of the spring baffle 19.

[0042] Specifically, in the design of the above structure, the first cross post, the second cross post, and the spring 110 form an elastic component. The user uses the push button 14 to drive the push rod 13 downward, thereby realizing the opening and closing between the upper locking tooth 16 and the lower locking tooth 18, so as to flexibly control the replacement of the non-woven fabric cleaning head 23.

[0043] Operating principle:

[0044] In use, the user holds the handle 1 and applies pressure at the bottom. Under the pressure, the outer box 22 opens outward, forming a 60-80 degree angle with the outer cover 21. Then, the handle 1 is removed, and the push button 14 is pushed down to move the push rod 13 downward. The push rod 13 presses down on the inner clamping rod 17, causing the lower clamping tooth 18 to move away from the upper clamping tooth 16. The clamped non-woven fabric cleaning head 23 automatically falls off. Then, the push button 14 is pushed down again, and the lower clamping tooth 18 rises under the action of the spring 110, forming a clamping effect with the upper clamping tooth 16 and the non-woven fabric cleaning head 23, thus completing the replacement of the non-woven fabric cleaning head 23. Example 2

[0045] A brush head, used in a disposable toilet brush according to Embodiment 1, the brush head includes,

[0046] Multiple layers of material sheets fixed at the top to each other in a stacked manner;

[0047] Among them, the top fixed part is the compression area (31);

[0048] Each layer is formed from at least one sheet of material, which is folded along a fold line to form a loop, and the fold line is located away from the compression area;

[0049] Each of the material sheets forms a ring with two parallel cuts (32) extending from away from the compression region (31);

[0050] At least one upper or lower surface of the compression region (31) has a punched recess (33).

[0051] The compression area 31 uses the punched holes of the punched recess 33 to press the material sheets together to fix them in place, so as to prevent them from being disassembled before use. However, the brush head can still be separated into fragments in the sewer or septic tank after use.

[0052] The ring formed by each material sheet has two parallel cuts 32, which allows the front end of the brush head to unfold when the brush head is pressed against the toilet surface during wiping, thereby increasing the wiping area.

[0053] The material sheet is made of water-degradable material.

[0054] In this embodiment, each layer consists of two overlapping material sheets folded along the fold line to form 4 layers, with a total of 10 groups on the top and bottom. An additional middle layer consists of one material sheet folded along the fold line to form 2 layers, for a total of 11 groups and 42 layers.

[0055] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
