Description

Stretch brush

The invention provides a elastic brush which can clean the wide and narrow parts of the inside and outside of the bottle, and has the elastic benefit of being able to apply the different size of the bottle.

There are always a variety of bottles of different sizes and depths in life, and these bottles are used almost every day. They are cleaned by a matching brush before use to meet the hygiene requirements. Brushes of different sizes lead to the disadvantages of wastage and difficulty in collecting.

More importantly, when the brushes are used to clean the bottle, the bristles cannot effectively clean the wide and narrow parts of the bottom edge of the bottom of the bottle or the neck of the top of the bottle. There is often a problem of insufficient cleaning, which will accumulate over time. Forming a layer of dirt with health concerns.

In order to solve the above disadvantages, the inventors have carefully studied and developed a spring brush to solve the inconvenience of using the existing brush.

The invention provides a stretch brush which is composed of at least one main handle, two elastic strips and a bottom brush.

The two elastic strips each have a sleeve that can be mounted on the lower end of the main handle The head is arranged such that the main handle and the second elastic strip are inverted T. As for the other end of the elastic strip, a brush ball is installed, and the elastic elastic deformation is performed through the synchronous upper or lower elastic strip, so that the lower end of the main handle can be inserted into the bottle. In the tank, the main handle rotates and moves up and down, so that the elastic strip can activate the brush ball to clean the inner circumference of the bottle with its own axial restoring force; the bottom brush is installed at the lower end of the main handle, except for limiting the elastic strip to come out Outside the lower end of the main handle, and can be used to clean the bottom of the bottle.

Therefore, the invention has a stretch brush and can be applied to different bottle cans. The economic benefits of inch use, and more importantly, the elastic strips can pre-press the ball with its own strong axial restoring force, and thus the inside and outside of the bottle can be cleaned.

Referring to Figures 1 to 4, the present invention includes at least a main shank 10 which may be made of stainless steel or wood strip or other environmentally friendly material having opposite upper and lower ends and a lower end having an external thread. An assembly portion 11 is provided with a force-applying portion 12 having a different shape and convenient for holding. The main handle 10 may have a circular or square shape or other shapes, and a square cross-section is used as shown in the figure. The structure is relatively strong and can prevent radial rotation; the length of the main shank 10 as shown in the figure is fixed, and it can also be replaced by the telescopic tube 10A, so as to adjust the height of the different tanks and to occupy no space. Convenience; at least two elastic strips 20A, which are strips made of any elastic material, so that one end of the elastic strip 20A has a sleeve 21 that can be mounted on the lower end of the main handle 10, so that the main handle 10 and the second elastic force The strip 20A is in an inverted T configuration as shown in Fig. 4, and the present invention utilizes the structure of the detachable ferrule 21 so that it can be selected in different lengths such as the long elastic strip 20B or the short elastic strip 20C as shown in Fig. 1. Specifically, the elastic strip 20A, the long elastic strip 20B or the short elastic strip 20 C, which can be applied to a variety of different sizes of bottles and cans 40, in addition, the other end of the elastic strip 20A is equipped with a brush ball 22, similarly know that when the brush ball 22 is damaged or fails, it must pass through the aforementioned removable hood 21 structure and replace the new elastic strip 20A, the new brush ball 22 can be replaced; when the invention wants to clean the bottle 40, it can be elastically deformed by the synchronous upper or lower elastic strip 20A, so that it can be The lower end of the main handle 10 is inserted into the bottle can 40, and then the main handle 10 is rotated and moved up and down, so that the elastic strip 20A can urge the brush ball 22 to clean the inner circumference of the bottle 40 with its own axial restoring force; The structure is shown in Figure 2, There is a through hole 211 for inserting the lower end of the main shank 10, so that the first assembly portion 11 of the main shank 10 penetrates from below to below the through hole 21, and a resilient piece 212 extends downwardly from the upper surface of the through hole 211. A gap 213 is formed between the elastic piece 212 and the through hole 211, and a claw 214 is protruded from the bottom edge of the elastic piece 212, so that the claw 214 is tightened to the lower end of the main handle 10 by a predetermined elastic force, thereby making the second elastic strip 20A 21 can be fixed in series and up; and a bottom brush 30 having a second assembly portion 31 that can be locked to the first assembly portion 11 for restricting the second elastic strip 20A from coming off the lower end of the main handle 10, and in the second The bottom end of the assembly portion 31 is provided with a bottom bristle 32 so that the bottom bristles 32 can be used to provide the bottom surface of the cleaning bottle can 40.

Please refer to FIG. 5, which illustrates the present invention through the finger synchronization The second elastic strip 20A is elastically deformed in the axial direction so that it can be inserted into the bottle can 40 together with the lower end of the main handle 10, and then the main handle 10 is rotated and moved up and down, so that the elastic strip 20A can actuate the brush ball 22 with its own axial restoring force. The top edge of the bottle 40 is strongly cleaned 41; as shown in Fig. 6, the invention is characterized in that the second elastic band 20A is elastically deformed by the finger synchronization, so that it can be inserted into the bottle 40 together with the lower end of the main handle 10, and then Cooperating with the main handle 10 to rotate and move up and down, the elastic strip 20A can be used to urge the brush ball 22 to clean the bottom edge 42 of the bottle 40 with its own axial restoring force; as seen from the fifth and sixth figures, the second The elastic strip 20A can pre-press the ball 22 with its own strong axial restoring force, and thus the inside and outside of the bottle can 40 is surely cleaned.

Please refer to FIG. 7 for illustrating that the present invention can move through left and right and The main shank 10 urging portion 12 is rotated to enable the bottom bristles 32 of the bottom brush 30 to completely clean the bottom surface of the can 40.

Please refer to FIG. 8 , which is the upper end of the main handle 10 of the present invention. An electric grip 50 for achieving a labor-saving operation and a better cleaning market. The electric grip 50 has a bearing housing 51 for supporting the upper end of the main handle 10, and a battery 52 is mounted therein, and can be battery-equipped. The 52-drive motor 53 allows the motor 53 to rotate the upper end of the main shank 10 in the bearing housing 51. The invention can also be powered by the mains. In the figure, the main handle 10 is a movable structure, which can reduce the volume and facilitate storage. When it is not limited thereto, it can also be a fixed structure.

In summary, the present invention is indeed unprecedented, and has the advantage of being able to apply the different bottle sizes by using a stretch brush, and the advantage of being able to clean the wide and narrow parts of the bottle, which is a technology. The high degree of creativity in the concept should be in accordance with the requirements of the patent application, and the application should be made according to law. However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the equivalent variations and modifications made by the scope of the present invention should still belong to the present invention.
