Description

Technical Field

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

[0002] As a common cleaning tool, brushes typically consist of two main functional components: a handle and a brush head. Traditional brushes (such as pot brushes and bowl brushes) connect the handle and brush head through a one-piece injection molding or adhesive bonding method. By utilizing the lever arm effect created by the length of the handle, users can obtain a large scrubbing torque with a small gripping force during cleaning, thereby improving the cleaning efficiency of stubborn stains.

[0003] However, because the brush head and handle are fixedly connected, when the bristles wear down, deform, or grow bacteria due to long-term use, users cannot replace the brush head separately and must discard the whole thing, which increases the user's cost. Utility Model Content

[0004] In view of this, the present invention provides a brush to solve the problem that in the prior art, the brush head and brush handle are fixedly connected, and when the bristles wear down, deform or grow bacteria due to long-term use, the user cannot replace the brush head separately and must discard the whole brush, which increases the user's usage cost.

[0005] To achieve one or more of the above objectives or other objectives, this utility model proposes a brush, including a handle and a brush head. The upper surface of the front end of the handle is distributed with multiple hooks, and the bending direction of the multiple hooks is consistent. The lower surface of the brush head is distributed with a ring-shaped fiber structure. The brush head can move in the opposite direction of the bending direction of the hooks to hook the ring-shaped fiber structure and fix the brush head to the front end of the handle, or move in the bending direction of the hooks to detach the ring-shaped fiber structure from the hooks and remove the brush head.

[0006] Preferably, the cross-sectional area of ​​the hook gradually decreases from its root to its end.

[0007] Preferably, the front end of the brush handle is composed of a mounting part and a connecting plate. The mounting part is integrally formed on the end of the brush handle and has a mounting surface.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this invention are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0025] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0027] like Figure 1-4As shown, a brush includes a handle 1 and a brush head. Multiple hooks 41 are distributed on the upper surface of the front end of the handle 1, with the hooks 41 bending in the same direction. A ring-shaped fiber structure is distributed on the lower surface of the brush head. During use, the brush head can move in the opposite direction of the hooks 41 to engage the ring-shaped fiber structure with the hooks 41, fixing the brush head to the front end of the handle 1. This allows the user to operate the brush head to scrub the surface of the object to be cleaned via the handle 1. When the brush head needs to be replaced, simply move it along the bending direction of the hooks 41 to disengage the ring-shaped fiber structure from the hooks 41, and remove the brush head for replacement. The uniform orientation of the hooks 41 openings also reduces the difficulty of removing the brush head, facilitating individual brush head replacement and preventing the entire brush from being discarded, thus reducing user costs.

[0028] In this embodiment, hooks 41 are distributed across the upper surface of the front end of the brush handle 1 in a matrix pattern to ensure the coverage of hooks 41, increase the number of connection points between the annular fiber structure and the front end of the brush handle 1, and improve the connection stability between the two.

[0029] Furthermore, the cross-sectional area of ​​the hook 41 gradually decreases from its root to its end. The large cross-section at the root ensures the connection strength with the front end of the brush handle 1, while the small cross-section at the end facilitates the hooking of the ring fiber structure, reducing the difficulty of connecting the two.

[0030] Furthermore, the front end of the brush handle 1 is composed of a mounting part 3 and a connecting plate 4. The mounting part 3 is integrally formed at the end of the brush handle 1 and has a mounting surface 31. The connecting plate 4 is detachably laid on the mounting surface 31. The two can be detachably connected by means of snap-fit ​​or threaded connection (not shown in the figure). Hooks 41 are evenly distributed on the side wall of the connecting plate 4 facing away from the mounting surface 31. The root of the hooks 41 is connected to the connecting plate 4 by ultrasonic process. Splitting the front end of the brush handle 1 into two parts makes it easier to process the hooks 41 and reduces production costs by assembly.

[0031] Furthermore, the end of the mounting part 3 away from the brush handle 1 is provided with a scraper head 35, and the end of the scraper head 35 is provided with a cutting edge 36. For stubborn adhering substances on the surface of the object to be cleaned, the user can use the cutting edge 36 of the scraper head 35 to scrape them off, further improving the cleaning ability of the brush.

[0032] Furthermore, the mounting part 3 is an oval-shaped plate, and the periphery of the connecting plate 4 is flush with the periphery of the mounting part 3. The rounded front end of the brush handle 1 makes it easier to fit the inner wall of the round container and avoid cleaning dead corners.

[0033] Furthermore, a snap-fit ​​cavity 32 is provided on the mounting surface 31, and snap-fit ​​positions 33 are distributed around the inner wall of the snap-fit ​​cavity 32. An annular block 42 is provided in the center on the side wall of the connecting plate 4 opposite to the hook 41. The annular block 42 is fitted inside the snap-fit ​​cavity 32, and snap-fit ​​structures 43 are distributed around the annular block 42. The snap-fit ​​structures 43 are snapped into the snap-fit ​​positions 33 one by one to restrict the axial movement of the annular block 42 relative to the snap-fit ​​cavity 32.

[0034] Furthermore, at least two positioning holes 34 are provided on the mounting surface 31. The positioning holes 34 are distributed around the periphery of the snap-fit ​​cavity 32. At least two positioning posts 44 are provided on the side wall of the connecting plate 4 opposite to the hook 41. When the annular block 42 is fitted into the snap-fit ​​cavity 32, the positioning posts 44 can be inserted into the positioning holes 34 one by one. Through the cooperation of the positioning posts 44 and the positioning holes 34, the relative rotation between the connecting plate 4 and the mounting part 3 is restricted, thereby improving the connection strength and stability between the connecting plate 4 and the mounting part 3.

[0035] Furthermore, the brush head includes a flock layer 5 and a scrubbing layer 6 fixedly laid on one side of the flock layer 5. A ring-shaped fiber structure is formed on the side of the flock layer 5 opposite to the scrubbing layer 6. The scrubbing layer 6 is used to peel off the adhering substances from the surface of the item to be cleaned. The scrubbing layer 6 is made of loofah, which not only uses more natural and pollution-free materials, but also reduces the manufacturing cost of the brush head.

[0036] In one embodiment, the scrubbing layer 6 can also be made of sponge material.

[0037] Furthermore, the velvet layer 5 and the brushed layer 6 are fixed together by a sewing process.

[0038] Furthermore, the rear end of the brush handle 1 is provided with a hanging hole 11 so that the user can hang the brush through the hanging hole 11 to drain it.

[0039] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model.
