Description

Technical Field

[0001] This utility model relates to the field of cleaning tool technology, and in particular to a toilet brush holder with an automatic flip-top lid. Background Technology

[0002] Disposable toilet brushes are a hygiene cleaning tool specifically designed for cleaning toilets. Their key feature is the separate handle and brush head; the brush head can be discarded after use, effectively avoiding the problem of bacterial growth that plagues traditional reusable toilet brushes.

[0003] A typical disposable toilet brush kit includes a matching toilet brush holder. This holder usually has two chambers: one for storing the brush handle (brush handle chamber) and the other for storing unused replacement brush heads (brush head chamber). The brush head chamber has an openable / closable cover, which is activated by a mechanism. Specifically, when the brush handle is inserted into the brush handle chamber, the mechanism is triggered, causing the cover to close; conversely, when the brush handle is removed, the mechanism opens the cover.

[0004] However, the structural design of the transmission mechanism in the existing technology has a significant flaw: its labor-saving effect is not good. In order to reliably drive the top cover to close when the brush handle is inserted, the brush handle itself often needs to be designed to be relatively heavy. This phenomenon directly restricts the lightweight design of the brush handle, making it difficult to meet the user's needs. Utility Model Content

[0005] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing an automatic flip-top toilet brush holder. Its structure is simple and reasonable, and it is easy to operate. Through the design of the force-saving lever, the brush handle can be made as light as possible while ensuring normal opening and closing of the top cover, making operation more effortless.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: The toilet brush holder with an automatic flip-top lid described in this utility model includes: A brush holder body, the brush holder body having a brush handle cavity and a brush head cavity, and a top cover hinged to the brush holder body to cooperate with the brush head cavity; A transmission mechanism is disposed within the brush holder body and is linked and cooperated with the upper cover; An elastic element that ensures the top cover always has a tendency to open; The transmission mechanism includes a transmission component and a linkage component. The transmission component has a rotation axis relative to the brush holder body. The transmission component can rotate relative to the brush holder body around the rotation axis. The transmission component has a linkage part and a trigger part. One end of the linkage component is linked to the linkage part, and the other end of the linkage component is linked to the upper cover. The trigger part extends to the brush handle cavity. Furthermore, the lever arm between the linkage part and the rotation axis is smaller than the lever arm between the trigger part and the rotation axis.

[0007] Furthermore, the rotation axis is located in the X-axis direction of the brush holder body, and the transmission member extends along the Y-axis direction of the brush holder body. When the trigger part moves along the Z-axis direction of the brush holder body, the transmission member rotates around the rotation axis.

[0008] Furthermore, the transmission component has a first end and a second end, the first end being rotatably connected to the brush holder body, the rotation axis being located at the first end, the triggering part being located at the second end, and the linkage part being located at the middle of the transmission component.

[0009] Furthermore, a transmission plate is fixedly connected to the second end.

[0010] Furthermore, the elastic element is a first spring, the lower end of the first spring abuts against the brush holder body, and the upper end of the first spring abuts against the transmission plate.

[0011] Furthermore, the elastic element is a second spring, the lower end of the second spring abuts against the brush holder body, and the upper end of the second spring abuts against the linkage element.

[0012] Furthermore, the elastic element is a torsion spring, which is sleeved on the first end of the transmission member. The torsion spring has a first torsion arm and a second torsion arm. There is a bent section between the first end and the second end of the transmission member. The first torsion arm abuts against the first end, and the second torsion arm abuts against the bent section.

[0013] Furthermore, the linkage has a first inclined wall that slopes upward from the inside out, and the upper cover has a first abutting portion that guides and cooperates with the first inclined wall.

[0014] Furthermore, the upper cover has a second inclined wall that slopes downward from the inside out, and the linkage has a second abutting portion that guides and cooperates with the second inclined wall.

[0015] Furthermore, the linkage component has a slot portion that cooperates with the transmission component. The linkage component is located within the slot portion. The inner wall of the slot portion includes a first abutting surface and a second abutting surface. The first abutting surface and the second abutting surface are disposed opposite to each other. The linkage component is limited to being located between the first abutting surface and the second abutting surface.

[0016] The beneficial effects of this utility model are as follows: The toilet brush holder with automatic flip-top described in this utility model drives the top cover to open or close through a transmission mechanism. The transmission mechanism includes a transmission component and a linkage component. The transmission component has a rotation axis relative to the brush holder body and can rotate relative to the brush holder body around the rotation axis. The transmission component has a linkage part and a trigger part. One end of the linkage component is linked to the linkage part, and the other end of the linkage component is linked to the top cover. The trigger part extends to the brush handle cavity. Furthermore, the lever arm between the linkage part and the rotation axis is smaller than the lever arm between the trigger part and the rotation axis. The rotation axis is located in the X-axis direction of the brush holder body, and the transmission component extends along the Y-axis direction of the brush holder body. When the trigger part moves along the Z-axis direction of the brush holder body, the transmission component rotates around the rotation axis. When the brush handle is inserted into the brush handle cavity, the weight of the brush handle acts on the trigger part, causing the transmission component to rotate around the rotation axis. The transmission component drives the linkage component to close the top cover. Conversely, when the brush handle is removed, the top cover opens under the elastic force of the elastic component.

[0017] Define the lever arm between the linkage and the rotation axis as L1, and define the lever arm between the trigger and the rotation axis as L2. According to the lever balance formula F1×L1=F2×L2, when L1<L2, the required F2<F1. The brush handle can close the top cover by applying a small force to the trigger. Through this force-saving lever design, the brush handle can be made as light as possible, making operation more effortless. Attached Figure Description

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

[0021] refer to Figures 1-13A disposable toilet brush kit includes a toilet brush holder, a brush handle 4 for use with the toilet brush holder, and several brush heads 5 for use with the brush handle 4. Each brush head 5 has a mounting protrusion 51. The brush handle 4 includes a handle shell, a clamping assembly, and a push rod. The clamping assembly includes at least two clamping portions 41 for clamping the mounting protrusion 51, and the clamping portions 41 are spaced apart. One end of each clamping portion 41 is slidably disposed within the handle shell along its length. The outer periphery of 1 and / or the inner wall of the brush handle shell has a pressing surface, which is inclined toward the side opposite to the clamping part 41 along the movement direction of the clamping part 41 near the brush handle shell; the push rod is used to push the clamping part 41 out of the brush handle shell; the brush handle 4 and brush head 5 described in this utility model are both prior art, and their specific structure / working principle can be referred to as a disposable toilet brush disclosed in Chinese Patent (Announcement No.: CN219803663U), so they will not be described in detail here.

[0022] like Figure 1 and Figure 2 The aforementioned toilet brush holder with automatic flip-top lid includes a brush holder body 1. The brush holder body 1 has a brush handle cavity 13 and a brush head cavity 14. The brush handle cavity 13 is used to store the brush handle 4, and the brush head cavity 14 is used to store unused replacement brush heads 5. (See reference) Figure 9 Specifically, the brush holder body 1 includes a base 11 and a housing 12 disposed on the base 11. The base 11 and the housing 12 cooperate to form the brush handle cavity 13 and the brush head cavity 14. The housing 12 is hinged with an upper cover 2 that cooperates with the brush head cavity 14. The upper cover 2 is used to protect unused brush heads 5 from contamination and dust. (See reference...) Figure 6 The housing 12 has a hinge groove 121 that mates with the upper cover 2. The upper cover 2 has a hinge member 21 that mates with the hinge groove 121. The hinge member 21 is inserted into the hinge groove 121 so that the upper cover 2 can rotate around the hinge point.

[0023] A transmission mechanism is provided inside the brush holder body 1. The transmission mechanism is linked with the upper cover 2 and is used to drive the upper cover 2 to open or close.

[0024] The elastic element ensures that the upper cover 2 always has an opening tendency; when the brush handle 4 is inserted into the brush handle cavity 13, it triggers the transmission mechanism, which drives the upper cover 2 to close against the elastic force of the elastic element; conversely, when the brush handle 4 is removed, the upper cover 2 opens under the elastic force of the elastic element.

[0025] refer to Figures 3-13 The transmission mechanism includes a transmission component 31 and a linkage component 32, as shown in the reference. Figure 3The transmission member 31 has a rotation axis 33 relative to the brush holder body 1. The transmission member 31 can rotate relative to the brush holder body 1 about the rotation axis 33. The transmission member 31 has a linkage part 311 and a trigger part 312. One end of the linkage part 312 is linked with the linkage part 311, and the other end of the linkage part 312 is linked with the upper cover 2. The trigger part 312 extends to the brush handle cavity 13. Furthermore, the lever arm between the linkage part 311 and the rotation axis 33 is smaller than the lever arm between the trigger part 312 and the rotation axis 33. The lever arm is between the two, the rotation axis 33 is located in the X-axis direction of the brush holder body 1, and the transmission member 31 extends along the Y-axis direction of the brush holder body 1. When the trigger part 312 moves along the Z-axis direction of the brush holder body 1, the transmission member 31 rotates around the rotation axis 33. Specifically, when the brush handle 4 is inserted into the brush handle cavity 13, the gravity of the brush handle 4 acts on the trigger part 312, causing the transmission member 31 to rotate around the rotation axis 33. The transmission member 31 drives the linkage member 32 to move, thereby driving the upper cover 2 to close. Conversely, when the brush handle 4 is removed, the upper cover 2 opens under the elastic force of the elastic member.

[0026] Define the lever arm between the linkage 311 and the rotation axis 33 as L1, and define the lever arm between the trigger 312 and the rotation axis 33 as L2. According to the lever balance formula F1×L1=F2×L2, when L1<L2, the required F2<F1. The brush handle 4 can close the upper cover 2 by applying a small force to the trigger 312. Through this force-saving lever design, the brush handle 4 can be made as light as possible, making the operation more effortless.

[0027] Preferably, in this embodiment, the transmission member 31 has a first end and a second end, the first end being rotatably connected to the brush holder body 1, and the rotation axis 33 being located at the first end, for reference... Figure 9 The base 11 has a first hole 111, and the first end is rotatably connected to the first hole 111. The trigger part 312 is located at the second end. Preferably, in this embodiment, reference... Figure 3 , Figure 4 , Figure 11 , Figure 12 and Figure 13 The second end is fixedly connected to a transmission plate 313. The brush handle 4 acts on the transmission plate 313 by gravity, which can effectively increase the force-bearing area and make the force more uniform. The linkage part 311 is located in the middle of the transmission part 31.

[0028] refer to Figures 9-10 Preferably, the base 11 has a connecting seat 112, the connecting seat 112 has a U-shaped opening 1121, the U-shaped opening 1121 faces upward, and the transmission plate 313 is located inside the U-shaped opening 1121.

[0029] Reference Figure 10 Preferably, there is a bent section 314 between the first end and the second end of the transmission member 31. The transmission member 31 is arranged in a "C" shape or in a loop shape, and the bent section 314 extends along the Y-axis direction of the brush holder body 1.

[0030] Reference Figures 3-9 In the first embodiment, the elastic member is the first spring 6. The connecting seat 112 has a first convex column 1122 that cooperates with the first spring 6. The lower end of the first spring 6 is sleeved on the first convex column 1122 and abuts against the connecting seat 112, and the upper end of the first spring 6 abuts against the transmission plate 313. Define the lever arm between the first spring 6 and the rotation axis 33 as L3, and define the spring force of the first spring 6 as F3. L3 > L1. With a relatively small spring force F3, the upper cover 2 can be opened.

[0031] Of course, in other embodiments, the position of the elastic member can also be changed.

[0032] Reference Figure 11 In the second embodiment, the elastic member is the second spring 7. The base 11 has a second convex column 113 that cooperates with the second spring 7. The lower end of the second spring 7 is sleeved on the second convex column 113 and abuts against the base 11, and the upper end of the second spring 7 abuts against the bottom of the linkage member 32. Define the lever arm between the second spring 7 and the rotation axis 33 as L4, and define the spring force of the second spring 7 as F4. L4 is close to L1. In this embodiment, L4 = L1. Compared with the first embodiment, F4 > F3.

[0033] Reference Figures 12-13 In the third embodiment, the elastic member is a torsion spring 8. The torsion spring 8 is sleeved on the first end of the transmission member 31. The torsion spring 8 has a first torsion arm 81 and a second torsion arm 82. There is a bent section 314 between the first end and the second end of the transmission member 31. The first torsion arm 81 abuts against the first end, and the second torsion arm 82 abuts against the bent section 314. Define the lever arm between the torsion spring 8 and the rotation axis 33 as L5, and define the spring force of the second spring 7 as F5. L5 < L1. Compared with the second embodiment, F5 > F4.

[0034] Preferably, in this embodiment, reference Figures 4-5 The linkage member 32 has a first inclined wall 321 that slopes upward from the inside to the outside and a first plane 3211 connected to the first inclined wall 321. The first plane 3211 is located at the top of the linkage member 32. The upper end edge of the first inclined wall 321 is connected to the first plane 3211. The upper cover 2 has a first abutting portion 22 that is in guiding cooperation with the first inclined wall 321.

[0035] Preferably, in this embodiment, the reference Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 11 , Figure 12 and Figure 13 The linkage 32 has a socket 322 that mates with the upper cover 2. A portion of the upper cover 2 is located within the socket 322. The upper cover 2 includes a connecting portion 23 that extends into the socket 322. The connecting portion 23 has a second inclined wall 231 that slopes downward from the inside out and a second plane 2311 that is connected to the second inclined wall 231. The upper edge of the second inclined wall 231 is connected to the second plane 2311. The inner wall of the socket 322 includes a second abutting portion 3221 that guides and mates with the second inclined wall 231.

[0036] When the brush handle 4 is inserted into the brush handle cavity 13, the weight of the brush handle 4 acts on the trigger part 312, causing the transmission member 31 to overcome the elastic force of the elastic member and rotate around the rotation axis 33. The transmission member 31 drives the linkage member 32 to move down, and the second plane 2311 abuts against the second abutting part 3221, pulling down the upper cover 2. As the linkage member 32 continues to move down, the second abutting part 3221 presses down on the second inclined wall 231, thereby pulling the upper cover 2 to flip inward and close.

[0037] Conversely, when the brush handle 4 is removed, the elastic force of the elastic element acts on the transmission element 31, causing the transmission element 31 to rotate around the rotation axis 33. The transmission element 31 drives the linkage element 32 to move upward, and the first plane 3211 abuts against the first abutting part 22, pushing open the upper cover 2, causing the upper cover 2 to flip open at a certain angle. As the linkage element 32 continues to move upward, the first abutting part 22 abuts against the first inclined wall 321 and moves obliquely upward along the inclined surface of the first inclined wall 321, causing the upper cover 2 to flip open.

[0038] refer to Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 11 , Figure 12Preferably, in this embodiment, the linkage 32 has a slot 323 that cooperates with the transmission member 31. The linkage 311 is located inside the slot 323. The inner wall of the slot 323 includes a first abutment surface 3231 and a second abutment surface 3232. The first abutment surface 3231 is located on the top inner wall of the slot 323, and the second abutment surface 3232 is located on the bottom inner wall of the slot 323. The first abutment surface 3231 and the second abutment surface 3232 are arranged opposite to each other. The linkage 311 is limited to the space between the first abutment surface 3231 and the second abutment surface 3232. Preferably, the first abutment surface 3231 is arc-shaped. The arc-shaped curved surface transition can effectively disperse stress, make the force more uniform, reduce the wear of the contact surface, and extend the service life of the transmission member 31.

[0039] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
