[0001] This utility model relates to car washing tools, and more particularly to a detailed brush for car washing. Background Technology

[0002] A detail brush is used when cleaning the interior or tires of a car. Figure 1 The image shows a detail brush 01 commonly used in the prior art. This detail brush 01 consists of a handle and bristles, with a hanging hole on the handle. When using it, the handle is held to sweep away dust or the bristles are wetted to scrub away dirt. When encountering harder dirt or dirt stuck in crevices, the usual practice is to hold half of the bristles with your hand to reduce the amplitude of the bristle swing and increase the brushing force.

[0003] However, maintaining this state requires holding the bristles with considerable force for a long time, which can easily cause hand fatigue. Furthermore, the way you hold the bristles cannot guarantee that they will be arranged in a regular manner, which reduces the brushing effect and makes the brushing work more laborious. Utility Model Content

[0004] This invention provides a detail brush for car washing, aiming to solve the above-mentioned technical problems.

[0005] This utility model is implemented as follows: a detailed brush for car washing includes a brush handle and bristles. A sleeve is slidably connected to the surface of the brush handle near the front end. A slider is fixedly connected to the inner side of the sleeve. An E-shaped groove is formed on the surface of the brush handle on the inner side of the sleeve. The slider slides in the E-shaped groove to gather the bristles at the front end of the sleeve. The front end of the sleeve bulges radially inward to form a limiting ring. The inner diameter of the limiting ring is slightly smaller than the outer diameter of the bristles as a whole.

[0006] Furthermore, the front and rear sections of the longitudinal portion of the E-shaped groove are not on the same straight line.

[0007] Furthermore, the brush handle surface inside the sleeve is engraved with a first mark indicating the position of the front section of the longitudinal portion of the E-shaped groove.

[0008] Furthermore, the end of the transverse portion of the E-shaped groove has a structure that matches the shape of the slider, and a limiting protrusion for engaging the slider is formed inward at that end.

[0009] Furthermore, the outer surface of the sleeve is engraved with a second mark indicating the position of the slider.

[0010] Furthermore, the bristles are embedded in a connecting block, which is detachably connected to the front end of the brush handle.

[0011] Furthermore, the connecting block has a longitudinally formed outlet groove, the front end of the brush handle has a ring groove, the E-shaped groove is connected to the ring groove through a transition groove, and the ring groove is connected to the outlet groove.

[0012] Furthermore, the brush handle surface on the inner side of the sleeve is engraved with a third mark indicating the position of the transition groove.

[0013] Furthermore, the limiting ring and the inner wall of the sleeve have a rounded transition.

[0014] Furthermore, the brush handle has a hanging hole on its surface near the rear end, and a notch is provided on one side of the hanging hole.

[0015] The car wash detail brush provided by this utility model utilizes a sleeve that can be fixed at different positions on the brush handle surface to gather or store the bristles.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] See Figures 2-10 This invention provides a detailed brush for car washing, including a handle 1 and bristles 2. A sleeve 3 is slidably connected to the surface of the handle 1 near the front end. A slider 4 is fixedly connected to the inner side of the sleeve 3. An E-shaped groove 5 is formed on the surface of the handle 1 on the inner side of the sleeve 3. The slider 4 slides in the E-shaped groove 5 to gather the bristles 2 at the front end of the sleeve 3. The front end of the sleeve 3 protrudes radially inward to form a limiting ring 6. The inner diameter of the limiting ring 6 is slightly smaller than the outer diameter of the bristles 2 as a whole.

[0031] The brush handle 1 has a double-curved surface in the middle for comfortable grip. A hanging hole 15 is provided on the surface of the brush handle 1 near the rear end, and a notch is provided on one side of the hanging hole 15. This embodiment of the utility model combines the hole and the hook. The car wash brush can be hung on a hooked rack using the hanging hole 15, or the car wash brush can be hung on the edge of an object, such as the opening of a clothing pocket, using the notch on one side of the hanging hole 15 for easy carrying.

[0032] The front end of the brush handle 1 is a cylindrical structure. A sleeve 3 is fitted onto and slidably connected to this cylindrical structure. When the sleeve 3 slides forward, it can tighten the bristles 2. To increase the tightness of the bristles 2 and give them a stronger brushing force, such as... Figure 7 As shown, in this embodiment of the utility model, a limiting ring 6 is set to restrain the brush bristles 2, and the sleeve 3 is in... Figure 2In the indicated state, the retaining ring 6 is abutting against the front end face of the brush handle 1, and the retaining ring 6 is bound to the root of the bristles 2. As the sleeve 3 slides forward, the retaining ring 6 gathers the scattered bristles 2 and leaves a portion of the bristles 2 outside the sleeve 3. The swing amplitude of this portion of the bristles 2 is limited by the retaining ring 6, and the bristles 2 are tightened. This portion of the bristles 2 can be used to clean harder or crevices of dirt by applying stronger brushing force.

[0033] When the sleeve 3 slides within the E-shaped groove 5 using the slider 4, the car wash detail brush can achieve three states, as shown in the diagram. Figure 2 , 9 As shown in Figures 1 and 10, the first state is the normal state where the bristles 2 are fully exposed, the second state is where only the front end of the bristles 2 is exposed, i.e., the state described above, and the third state is where the bristles 2 are completely retracted into the sleeve 3.

[0034] like Figure 4 As shown, the end of the transverse portion of the E-shaped slide groove 5 has a structure that matches the shape of the slider 4, and a limiting protrusion 8 for engaging the slider 4 is formed inward at this end. In the above three states, the slider 4 inside the sleeve 3 is engaged with the end of the rear transverse portion, the end of the middle transverse portion, and the end of the front transverse portion of the E-shaped slide groove 5 by the limiting protrusion 8, respectively.

[0035] To facilitate quick and easy positioning of the transverse portion of the E-shaped groove 5 in the three states mentioned above when operating sleeve 4, and to provide a stronger sense of confirmation during operation, such as... Figure 3 As shown, in this embodiment of the utility model, the E-shaped groove 5 is configured such that the front and rear sections of the longitudinal portion of the E-shaped groove 5 are not on the same straight line.

[0036] With this setup, when the car wash detail brush transitions from the first state to the second state, the sleeve 3 can be rotated to move the slider 4 out of the end of the rear horizontal section of the E-shaped groove 5 until the slider 4 is against the inner wall of the rear section of the longitudinal section of the E-shaped groove 5. The sleeve 3 is then pushed forward until the slider 4 is against the inner wall of the E-shaped groove 5 again. Then, the sleeve 3 is rotated to engage the slider 4 into the end of the middle horizontal section of the E-shaped groove 5.

[0037] Sleeve 3 can be made of transparent material. If increased structural strength is required, it can also be made of opaque material. When made of opaque material, to facilitate determining the position of slider 4 within the E-shaped groove 5, and to facilitate determining the specific direction of the groove transition between the rear and front sections of the longitudinal portion of the E-shaped groove 5, such as... Figure 6 , 8As shown, in this embodiment of the utility model, a first mark 7 indicating the position of the front section of the longitudinal part of the E-shaped groove 5 is engraved on the surface of the brush handle 1 inside the sleeve 3, and a second mark 9 indicating the position of the slider 4 is engraved on the outer surface of the sleeve 3.

[0038] With this setup, when the car wash detail brush is in its second state, the position of the front section of the longitudinal part of the E-shaped groove 5 can be determined from the exposed first mark 7. When the car wash detail brush transitions from the second state to the third state, the sleeve 3 can be rotated to move the slider 4 out of the middle part of the E-shaped groove 5, aligning the second mark 9 on the surface of the sleeve 3 with the first mark 7. Then, the sleeve 3 is pushed forward to slide the slider 4 into the front section of the longitudinal part of the E-shaped groove 5 until it is against the inner wall of the E-shaped groove 5. Finally, the sleeve 3 is rotated to engage the slider 4 into the end of the front transverse part of the E-shaped groove 5.

[0039] To improve the smoothness of slider 4 when sliding and changing direction in E-shaped groove 5, the corners of E-shaped groove 5 are set to be rounded.

[0040] In one embodiment of this utility model, in order to facilitate the replacement of worn bristles 2, the bristles 2 are attached to a connecting block 10, and the connecting block 10 is detachably connected to the front end of the brush handle.

[0041] like Figure 5 As shown, the rear end of the connecting block 10 has an internal thread, and correspondingly, the end face of the brush handle 1 has a groove with an external thread. The connecting block 10 is threadedly connected to the front end of the brush handle 1, which facilitates the replacement of the brush bristles 2.

[0042] In this embodiment, the connecting block 10 abuts against the front end face of the brush handle 1, and the inner surface of the front end of the sleeve 3 abuts against the front end face of the connecting block 10. The sleeve 3 needs to be disassembled when replacing the brush bristles 2. Based on this embodiment, such as... Figure 3 As shown, the connecting block 10 has an outlet groove 11 in the longitudinal direction, the front end of the brush handle 1 has an annular groove 12, the E-shaped groove 5 is connected to the annular groove 12 through a transition groove 13, and the annular groove 12 is connected to the outlet groove 11.

[0043] When the car wash brush is in the third state mentioned above, continue to rotate the sleeve 3 to move the slider 4 out of the end of the front horizontal part of the E-shaped slide groove 5, push the sleeve 3 forward to make the slider 4 enter the transition slide groove 13, and then enter the annular slide groove 12. Use the slider 4 to slide in the annular slide groove 12 to find the outlet slide groove 11, and let the slider 4 slide out from the outlet slide groove 11 to disassemble the sleeve 3.

[0044] In this embodiment, the corner at the connection between the outlet chute 11 and the annular chute 12 is a rounded corner structure, which facilitates the sliding of the slider 4.

[0045] The brush handle 1 on the inner side of the sleeve 3 is engraved with a third mark 14 indicating the position of the transition groove 13, which facilitates quick positioning of the transition groove 13.

[0046] After replacing bristles 2, the sleeve 3 needs to be reversed and put back onto bristles 2. To prevent bristles 2 from bending inside the sleeve 3, as follows: Figure 7 As shown, in this embodiment of the utility model, the limiting ring 6 and the inner wall of the sleeve 3 are set to a rounded transition. When the outer ring bristles 2 are released from the rounded corner, they can be guided to converge inward, so that the bristles 2 can pass through the sleeve 3 more smoothly.

[0047] In all the embodiments of this utility model, the engagement between the slider 4 and the E-shaped groove 5 is achieved by rotating the sleeve 3 in the same direction, and the disengagement of the slider 4 from the E-shaped groove 5 is achieved by rotating the sleeve 3 in the opposite direction, ensuring consistency of operation and convenience of use.

[0048] In summary, when the car wash detail brush provided in this embodiment is used, when the car wash detail brush is in the position of Figure 2 In the indicated state, the slider 4 inside the sleeve 3 is engaged in the E-shaped groove 5, allowing the brush handle 1 to be held and used to clean dust from the interior trim or tire surface. When encountering harder dirt or dirt trapped in crevices, rotate the sleeve 3 until the slider 4 is against the E-shaped groove 5, push the sleeve 3 forward until the slider 4 is against the E-shaped groove 5, and then rotate the sleeve 3 in the opposite direction until the slider 4 is engaged in the E-shaped groove 5. This positions the front end of the sleeve 3 in a state where the bristles 2 are gathered, with a portion of the bristles 2 protruding from the sleeve 3. Figure 9 As shown. After use, rotate the sleeve 3 to align the second mark 9 with the first mark 7, push the sleeve 3 forward until the slider 4 is against the E-shaped groove 5, then rotate the sleeve 3 in the opposite direction until the slider 4 is engaged in the E-shaped groove 5, thereby allowing the front end of the sleeve 3 to hold the brush bristles 2, as shown. Figure 10 As shown.

[0049] When the brush bristles need to be replaced (brush 2), the car wash detail brush should be in position. Figure 10 In the indicated state, rotate sleeve 3 to align the second mark 9 with the third mark 14, push sleeve 3 forward until slider 4 enters transition groove 13, then enters annular groove 12, rotate and push sleeve 3 forward with slight force until slider 4 slides into outlet groove 11, then remove sleeve 3. Rotate connecting block 10 to disengage it from brush handle 1, replace with another connecting block 10 with bristles 2, thread the connecting block 10 to brush handle 1, put sleeve 3 back onto bristles 2, align the second mark 9 with outlet groove 11 to make slider 4 enter outlet groove 11, then align the second mark 9 with transition groove 13 to make slider 4 enter transition groove 13, finally use the second mark 9 to make slider 4 reach the desired position along E-shaped groove 5.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
