Description

Technical Field

[0001] The utility model relates to the technical field of paint touch-up brushes, in particular to an improved structure of a paint touch-up brush head. Background Art

[0002] Paintbrushes are widely used in home decoration and industrial painting, primarily for applying paint, coatings, and glue. Traditional paintbrushes require frequent dipping in paint, making them inconvenient to use. To address this issue, a press-type paint brush has been proposed in the prior art. This type of paint brush typically has a paint flow channel inside. During use, the worker squeezes the paint bottle, causing the paint in the bottle to flow through the paint flow channel onto the bristles, eliminating the need for repeated dipping. Currently, this type of paint brush and paint bottle typically utilize a threaded connection. However, due to factors such as manufacturing errors, the threaded fit gap can easily become excessive, affecting the sealing of the connection. Furthermore, during the process of replacing the paint bottle, the paint in the paint flow channel can easily flow out. Based on this, the present application proposes an improved structure for a touch-up paint brush head. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] The utility model provides an improved structure of a paint touch-up brush head, comprising a connecting part 1 and a bristle fixing part 2. The inner wall of the connecting part 1 is provided with an internal thread, and the paint touch-up brush head can be threadedly connected to a bottle for storing repair paint that is compatible with it through the internal thread. A sealing ring 6 is fixedly connected to the middle part of the top of the inner cavity of the connecting part 1, and the sealing ring 6 is adapted to the bottle mouth of the bottled repair paint. When the paint touch-up brush head is threadedly connected to the repair paint bottle, the sealing ring 6 can fit tightly against the inner wall of the bottle mouth to prevent the repair paint from leaking, thereby improving the sealing performance of the connection between the paint touch-up brush head and the bottled repair paint bottle.

[0022] A paint outlet 7 is provided in the middle of the top of the connecting part 1, and the paint outlet 7 is located in the middle of the inner cavity of the sealing ring 6. When the paint touch-up brush head is connected to the bottle of repair paint, the staff squeezes the repair paint bottle, and the repair paint stored in the bottle can be discharged through the paint outlet 7.

[0023] The middle part of the top of the connecting part 1 is fixedly connected to the bristle fixing part 2, the middle part of the inner cavity of the bristle fixing part 2 is fixedly connected to the paint flow channel 3, and the bottom of the inner cavity of the bristle fixing part 2 is provided with a paint inlet hole 4, and the paint outlet hole 7 is connected to the paint inlet hole 4. The paint liquid in the paint outlet hole 7 can flow into the paint flow channel 3 through the paint inlet hole 4.

[0024] The paint flow channel 3 is a flat hollow structure. The length of the paint flow channel 3 is greater than the top aperture of the paint outlet hole 7, and the width of the inner cavity of the paint flow channel 3 is less than the bottom aperture of the paint outlet hole 7. The size of the paint flow channel 3 can be set according to needs and is not limited here. Through the setting of the paint flow channel 3, the paint can be dispersed so that the paint liquid can fully contact the bristles installed on the bristle fixing part 2, which is convenient for brushing.

[0025] A sealing ball 5 is movably connected in the cavity formed by the paint outlet hole 7 and the paint inlet hole 4.

[0026] The paint outlet hole 7 is a conical structure. The aperture at the top of the paint outlet hole 7 is larger than the outer diameter of the sealing ball 5, and the aperture at the bottom of the paint outlet hole 7 is smaller than the outer diameter of the sealing ball 5. Under the action of gravity, the sealing ball 5 can seal the paint outlet hole 7 to prevent the paint liquid in the brush head from flowing out under the action of gravity, making it easy to connect the brush head with different bottled repair paints.

[0027] The aperture of the paint inlet hole 4 is larger than the outer diameter of the sealing ball 5, the bottom of the paint flow channel 3 is fixed to the top of the paint inlet hole 4, and the distance between the top of the paint inlet hole 4 and the bottom of the paint outlet hole 7 is larger than the outer diameter of the sealing ball 5. With this arrangement, when the brush head is in use, the sealing ball 5 can be separated from the bottom of the paint outlet hole 7, releasing the seal on the paint outlet hole 7, and the sealing ball 5 cannot seal the top of the paint inlet hole 4, thereby facilitating the paint liquid to flow into the inner cavity of the paint flow channel 3.

[0028] The sizes of the paint inlet 4, the blocking ball 5 and the paint outlet 7 can be set according to the requirements and are not limited here. The blocking ball 5 can be made of steel ball.

[0029] In summary: when the improved structure of the paint touch-up brush head is used, the bristles 9 are fixed in the bristle fixing part 2, and the paint flow channel 3 is inserted into the groove at the bottom end of the bristles 9. The user screws the paint touch-up brush head and the bottled repair paint 8 adapted thereto, as shown in FIG. Figure 1 and Figure 2 As shown, the paint touch-up brush head is installed on the bottled repair paint 8. At this time, the sealing ring 6 is tightly fitted with the inner wall of the bottle mouth of the bottled repair paint 8, thereby improving the sealing performance of the connection between the paint touch-up brush head and the bottled repair paint 8 and preventing the paint liquid from leaking out. When the paint touch-up brush head is in use, the staff squeezes the bottled repair paint 8. Under the action of the squeezing force, the repair paint enters the inner cavity of the paint flow channel 3 through the paint outlet 7 and the paint inlet 4. The paint liquid is evenly distributed in the paint flow channel 3, and the paint liquid flowing out of the paint flow channel 3 can fully contact the hairs on the brush bristles 9. When the paint touch-up brush head is separated from the bottled repair paint 8, and the paint touch-up brush head is as shown in FIG. Figure 2 In the state shown, under the action of gravity, the sealing ball 5 seals the paint outlet 7 to prevent the paint liquid remaining in the paint touch-up brush head from flowing out.

[0030] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology and will not be described in detail here. The contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and modifications can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
