Description

Technical Field

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

[0002] Current brushes have a straight handle and brush head structure. This structure makes it difficult to reach corners and other hard-to-reach areas. Furthermore, the coaxial straight structure makes it difficult to precisely match the force applied by the arm and wrist to the force required on the brush bristles during use. This necessitates frequent wrist adjustments, leading to muscle fatigue and increased grip strength. Therefore, they are very inconvenient to use. Utility Model Content

[0003] The purpose of this invention is to provide a brush that solves the problems mentioned in the background section.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A brush includes a brush head and a brush handle. The brush handle includes a grip and a connecting part. The connecting part is connected to one end of the grip and includes two connecting branches. A connecting strip is provided at the bottom of the connecting branch, and a connecting protrusion is provided on the connecting strip. The brush head includes a bristle seat. An mounting hole for installing bristles is provided in the middle of the bristle seat. A connecting boss is provided at the top of the bristle seat. A connecting groove adapted to the connecting strip is provided on the connecting boss. A connecting slot adapted to the connecting protrusion is provided in the connecting groove. An angle is formed between the bottom end face of the connecting part and the axis of the grip.

[0006] Furthermore, the included angle ranges from 30° to 60°.

[0007] Furthermore, the bottom of the connecting protrusion is provided with an upwardly inclined hook.

[0008] Furthermore, a connection hole is provided at the end of the connecting part away from the brush head.

[0009] Furthermore, the grip portion is provided with anti-slip grooves.

[0010] Furthermore, a mounting groove is provided at the bottom of the connecting part and at one end of the connecting strip.

[0011] Furthermore, the bristles are attached to the mounting holes by adhesive.

[0012] Beneficial effects:

[0013] The brush in this invention has a simple structure and is easy to use. The brush head is connected to the brush handle by a snap-fit ​​connection, and there is an angle between the axis of the brush handle and the working surface of the brush head, thereby optimizing the force direction when holding the brush handle and adapting to certain dead angle areas to expand the application scenarios.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, an indirect connection through an intermediate medium, or a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0022] In addition, unless otherwise specified, the components used in the following embodiments are all existing components, and their corresponding connection methods can also be achieved through conventional technical means, which will not be described in detail in this application. The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example

[0024] This embodiment provides a brush, specifically a paint brush for applying paint. For example... Figures 1 to 5 As shown, it includes a brush head 2 and a brush handle 1. The brush handle 1 is snapped onto the brush handle 1 to facilitate the replacement of the damaged brush head 2 without replacing the entire brush, thereby reducing the cost of long-term use.

[0025] The brush handle 1 includes a gripping part 11 and a connecting part 12. The connecting part 12 is connected to one end of the gripping part 11 and includes two connecting branches 18. The two connecting branches 18 gradually separate from top to bottom, forming a hollow shape in the middle, which reduces the amount of material used in the brush handle 1 and lowers the overall weight, making it less tiring for workers to hold for a long time. A connecting strip 13 is provided at the bottom of the connecting branch 18, and a connecting protrusion 14 is provided on the connecting strip 13. The brush head 2 includes a bristle base with a mounting hole 22 for installing bristles in the middle. A connecting boss 21 is provided at the top of the bristle base, and a connecting groove 23 that matches the connecting strip 13 is provided on the connecting boss 21. Therefore, the connecting part 12 of the brush handle 1 can insert the connecting strip 13 into the connecting groove 23. The matching of the connecting strip 13 and the connecting groove 23 enables quick alignment and initial fixation of the brush head 2 and the brush handle 1, facilitating quick installation by workers. Furthermore, the connecting groove 23 is provided with a connecting slot 24 that matches the connecting protrusion 14. When the connecting strip 13 is inserted into the connecting groove 23, the connecting protrusion 14 can be engaged in the connecting slot 24, further securing the brush head 2. The connection between the connecting protrusion 14 and the connecting slot 24 provides secondary positioning of the brush head 2, preventing it from sliding or falling off during operation and ensuring effective painting. An angle is formed between the bottom end face of the connecting part 12 and the central axis of the holding part 11, resembling a wrench. The connecting part 12 is parallel to the end face of the brush head 2, and there is also an angle between the holding part 11 and the working end face of the brush head 2. This allows the direction of force applied when holding the brush to better align with the natural posture of the arm, reducing wrist fatigue when painting above the wall surface.

[0026] Preferably, the included angle range is 30° to 60°. This angle range allows the wrist and arm to maintain a natural and relaxed force exertion posture without excessive compensation. After continuous operation for a certain period of time, muscle fatigue can still be controlled at a low level.

[0027] Preferably, the bottom of the connecting protrusion 14 is provided with an upwardly inclined hook 19. The hook 19 makes it easier for the connecting protrusion 14 to slide into the connecting slot 24 when it is inserted. After it is inserted, the inclined surface forms a barb, which increases the resistance to pulling out, thereby further preventing the brush head 2 from accidentally falling off when it is under tension.

[0028] Preferably, the end of the connecting part 12 away from the brush head 2 is provided with a connecting hole 16, through which the brush can be hung on a hook on the wall, thereby facilitating the storage of the brush and avoiding random placement.

[0029] Preferably, the grip portion 11 is provided with an anti-slip groove 15, which can increase the friction between the palm and the brush handle 1, allowing the operator to grip the brush handle 1 more firmly.

[0030] Preferably, a mounting groove 17 is provided at the bottom of the connecting part 12 and at one end of the connecting strip 13. The mounting groove 17 is inverted U-shaped, and the width and depth of the opening are adapted to the thickness of the rim of common paint buckets on the market. Therefore, the mounting groove 17 allows the brush to be temporarily hung on the paint bucket when painting, avoiding random placement that could cause paint on the brush to get on other places.

[0031] Preferably, the bristles are attached to the mounting hole 22 with glue. The type of glue can be a type commonly used in the field for bristle implantation. The specific method for installing the bristles can be any of the bristle installation methods currently available on the market, and is not limited here.

[0032] Although the embodiments of this utility model have been described in the specification, these embodiments are merely illustrative and should not limit the scope of protection of this utility model. Various omissions, substitutions, and modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
