Description

Technical Field

[0001] This utility model relates to the field of brush technology, and in particular to a brush with an adjustable angle. Background Technology

[0002] A brush, generally referring to a tool made of bristles, palm fibers, plastic filaments, or metal wire, is used to remove dirt or apply ointments and oils, playing a vital role in daily cleaning. Traditional brushes have a relatively simple structure, with the brush head and handle usually fixed together, and the angle and length are not adjustable. This makes it difficult to effectively clean certain surfaces or corners, thus reducing cleaning efficiency and quality.

[0003] When cleaning corners, furniture edges and crevices, and objects with complex curved surfaces, users often need to constantly change the way they hold the brush handle because the angle of traditional brushes is fixed. They may even have to squat, bend over, or twist their bodies to adapt to the angle requirements between the brush and the cleaning surface. This not only leads to low cleaning efficiency, but also causes users to experience physical fatigue and muscle soreness due to prolonged uncomfortable postures, increasing the difficulty and labor intensity of cleaning work. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a brush with an adjustable angle, solving the technical problem that existing brushes have a fixed connection between the brush head and handle, and the angle and length are not adjustable, making it difficult to clean dirt in corners and crevices. This invention achieves the goal of adjusting the cleaning angle and length of the brush to adapt to different cleaning scenarios.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a brush that is easy to adjust the angle, including a brush head installed at the left end of the brush handle, an adjustment mechanism for adjusting the angle of the brush head is provided at the connection between the brush handle and the brush head, and a distance adjustment mechanism for extending the length of the brush handle is provided on the brush handle.

[0006] The adjustment mechanism includes a U-shaped seat installed on the left end of the brush handle, a flip block that matches the U-shaped seat is installed on the right side of the brush head, and a rotating shaft that is rotatably connected to a rotating hole in the U-shaped seat is installed on the flip block. A locking component is provided in the U-shaped seat to adjust and fix the flip angle of the brush head.

[0007] A further improvement is that the locking assembly includes an adjustment cavity opened inside the front end of the U-shaped seat, and toothed rings and compression springs are respectively installed on the inner walls of the two sides of the adjustment cavity. The front end of the rotating shaft is equipped with a meshing toothed ring that is connected to one end of the compression spring and engages with the toothed ring.

[0008] A further improvement is that the rear end of the rotating shaft extends to the outside of the rotating hole opened on the U-shaped seat.

[0009] A further improvement is that the distance adjustment mechanism includes a rotating ring mounted on the brush handle, a ring sleeve mounted in the middle of the brush handle, and the ring sleeve being rotatably connected to the rotating ring through a groove on its inner wall that matches the rotating ring. The ring sleeve has a spiral groove in a serpentine shape. A sliding sleeve is mounted inside the ring sleeve, and a guide groove is provided on the sliding sleeve. An extension rod is slidably connected to the sliding sleeve from left to right, and a protrusion is mounted on the extension rod that is slidably connected to the spiral groove and the guide groove. A distance fixing component is mounted on the brush handle to limit the extension length of the brush handle.

[0010] A further improvement is that the ring is fitted with an anti-slip sleeve for easy screwing, and an annular toothed groove is provided on the right side of the ring.

[0011] A further improvement is that the distance-fixing component includes a fixing box installed on the brush handle, and a pull rod is slidably connected to the through hole in the fixing box. A conical tooth block that meshes with the annular tooth groove is installed on the left end of the pull rod, and a tension spring with one end installed on the inner wall of the fixing box is sleeved on the pull rod.

[0012] By employing the above technical solution, this utility model provides a brush with an easily adjustable angle, which has at least the following beneficial effects:

[0013] 1. This utility model inserts the brush head into the curved surface gap. As force is applied to the brush handle, the brush head, constrained by the curvature of the curved surface gap, drives the rotating shaft on its right-end flipping block to rotate within the U-shaped seat at the left end of the brush handle. This allows the brush head to rotate freely within the curved surface gap for free angle adjustment, thus enabling the cleaning of the curved surface gap.

[0014] 2. This utility model involves pressing the rotating shaft to push the meshing toothed ring to squeeze the compression spring and disengage it from the toothed ring. Then, the rotating shaft is rotated to adjust the angle of the brush head. After the angle adjustment is completed, the rotating shaft is released, and the compression spring resets under its own elasticity, thereby pushing the meshing toothed ring to reset and re-engage with the toothed ring, thus completing the angle fixation of the brush head.

[0015] 3. This utility model rotates the ring sleeve, causing it to rotate along the rotating ring, thereby driving the protrusion to move along the spiral groove and guide groove, thereby pushing the extension rod connected to it to slide out from the sliding sleeve. The conical toothed block engages with the annular toothed groove on the ring sleeve, thereby extending the length of the brush handle and allowing the brush head to penetrate deep into the crevices for cleaning.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Addressing the problem that existing brushes with fixed brush heads and handles, lacking adjustable angle and length, struggle to clean dirt from corners and crevices, this embodiment provides a brush with adjustable angle. Please refer to... Figures 1-5This embodiment provides an adjustable brush with adjustable angle, capable of adjusting the cleaning angle and length of the brush to adapt to different cleaning scenarios. The adjustable brush includes a brush head 2 mounted on the left end of a handle 1. An adjustment mechanism 3 for adjusting the angle of the brush head 2 is provided at the connection between the handle 1 and the brush head 2. An adjustment mechanism 4 for extending the length of the handle 1 is provided on the handle 1. The adjustment mechanism 3 adjusts the tilt angle of the brush head 2, allowing it to be inserted into crevices at different angles for cleaning. The adjustment mechanism 4 extends the length of the handle 1, enabling thorough cleaning of deeper corners and crevices.

[0031] Because the brush head and handle of existing brushes are fixedly connected, and their angle and length are not adjustable, it is difficult to clean dirt in corners and crevices. Therefore, this device is equipped with an adjustment mechanism 3. The adjustment mechanism 3 includes a U-shaped seat 31 installed on the left end of the brush handle 1. A flipping block 32 matching the U-shaped seat 31 is installed on the right side of the brush head 2. A rotating shaft 33 is installed on the flipping block 32 and rotatably connected to the rotating hole opened on the U-shaped seat 31. A locking component 34 is provided in the U-shaped seat 31 to adjust and fix the flipping angle of the brush head 2. When it is necessary to brush the curved surface crevices, the brush head 2 is inserted into the curved surface crevices. As force is applied to the brush handle 1, the brush head 2 drives the rotating shaft 33 on its right flipping block 32 to rotate in the U-shaped seat 31 at the left end of the brush handle 1 under the limitation of the curvature of the curved surface crevices. This allows the brush head 2 to rotate in accordance with the curved surface crevices to adjust the angle and clean the curved surface crevices.

[0032] However, if the angle of the brush head 2 is not fixed after the adjustment, the brush head 2 will rotate continuously when it is subjected to force for cleaning, which will affect the cleaning effect. Therefore, the device is also equipped with a locking component 34. The locking component 34 includes an adjustment cavity 341 opened inside the front end of the U-shaped seat 31, and toothed rings 342 and compression springs 343 are respectively installed on the inner walls of the two sides of the adjustment cavity 341. The front end of the rotating shaft 33 is equipped with a meshing toothed ring 344 that is connected to one end of the compression spring 343 and meshes with the toothed ring 342.

[0033] The rear end of the rotating shaft 33 extends to the outside of the rotating hole on the U-shaped seat 31. When it is necessary to adjust the angle of the brush head 2, press the rotating shaft 33 inward to make it move inward along the rotating hole on the U-shaped seat 31. At this time, the meshing toothed ring 344 squeezes the compression spring 343 and disengages from the toothed ring 342. Then, rotate the rotating shaft 33 to adjust the angle of the brush head 2. After the angle adjustment is completed, release the rotating shaft 33. The compression spring 343 returns to its original position under its own elasticity, thereby pushing the meshing toothed ring 344 to return to its original position and re-engage with the toothed ring 342, thus completing the angle fixation of the brush head 2.

[0034] Example 2

[0035] Based on Example 1, such as Figures 1-5 As shown, since the length of the brush handle 1 of the existing brush cannot be adjusted, the brush head 2 cannot be inserted into deep crevices for cleaning. Therefore, this device is also equipped with a distance adjustment mechanism 4. The distance adjustment mechanism 4 includes a rotating ring 41 installed on the brush handle 1, a ring sleeve 42 installed in the middle of the brush handle 1, and the ring sleeve 42 is rotatably connected to the rotating ring 41 through a ring groove on its inner wall that matches the rotating ring 41. The ring sleeve 42 has a serpentine spiral groove 43, and a sliding sleeve 44 is installed inside the ring sleeve 42. The sliding sleeve 44 has a guide groove 45, and an extension tube is slidably connected to the sliding sleeve 44. The extension rod 46 is equipped with a protrusion 47 that is slidably connected to the spiral groove 43 and the guide groove 45. The brush handle 1 is equipped with a distance-fixing component 48 that limits the extension length of the brush handle 1. The ring sleeve 42 is rotated so that it rotates along the rotating ring 41 on the brush handle 1, thereby driving the protrusion 47 to move along the spiral groove 43 opened on the ring sleeve 42 and the guide groove 45 opened on the sliding sleeve 44, thereby pushing the extension rod 46 connected to it to slide out from the sliding sleeve 44, thereby extending the length of the brush handle 1 and allowing the brush head 2 to penetrate into the crevices for cleaning.

[0036] The ring 42 is equipped with an anti-slip sleeve that is easy to twist. The anti-slip sleeve makes it easier for people to apply force to rotate the ring 42. The ring 42 has an annular toothed groove on the right side.

[0037] After the brush handle 1 is extended, it is not fixed. This will cause the protrusion 47 to return to its original position due to the reaction force when brushing, thus causing the brush handle 1 to gradually return to its original position and become shorter. Therefore, the device is also equipped with a distance fixing component 48. The distance fixing component 48 includes a fixing box 481 installed on the brush handle 1, and a pull rod 482 is slidably connected to the through hole in the fixing box 481. A conical tooth block 483 that meshes with the annular tooth groove is installed on the left end of the pull rod 482, and one end of the pull rod 482 is fitted onto the fixing box 481. Before the brush handle 1 is extended by rotating the ring sleeve 42, the tension spring 484 on the inner wall pulls the pull rod 482 backward and compresses the tension spring 484, causing the tapered tooth block 483 at its left end to disengage from the annular tooth groove on the right side of the ring sleeve 42. After the brush handle 1 is extended to the required length, the ring sleeve 42 is released, and the tension spring 484 returns to its original position under its own elasticity, thereby driving the pull rod 482 to return to its original position, so that the tapered tooth block 483 is engaged in the annular tooth groove on the ring sleeve 42, thereby completing the fixation of the extended length of the brush handle 1.
