Description

Technical Field

[0001] The utility model relates to the field of spring needles, in particular to a universal contact type liquid-guiding and flow-suppressing spring needle. Background Art

[0002] In modern industry and daily life, the precise control and uniform coating of liquids are increasingly widely used, especially in the cosmetics, medical, coatings and other industries. Traditional liquid distribution systems often have problems such as uneven liquid distribution or inaccurate control. Therefore, it is particularly important to develop a device that can accurately control the liquid flow rate and achieve uniform liquid coating.

[0003] Most of the liquid dispensing devices on the market currently control the amount of liquid flowing out based on gravity or mechanical pressure. These methods often make it difficult to accurately control the release of liquid and are prone to liquid leakage or overflow due to external conditions such as tilt or vibration. In addition, these systems are difficult to achieve uniform coating in all directions and often require manual or mechanical assistance to adjust the direction, making the operation complicated and increasing costs. Summary of the invention

[0004] In order to solve the above problems, the utility model provides a universal contact liquid-guiding and flow-suppressing spring needle, a head ball with universal rotation capability, and a liquid-guiding system with a built-in spring and a flow-suppressing column, which can effectively seal the liquid through the internal structure without external force, and accurately control the release amount and direction of the liquid when subjected to external force, thereby achieving 360° all-round uniform coating.

[0005] The utility model is realized by the following technical scheme: a universal contact type liquid guiding and flow inhibiting spring needle, comprising:

[0006] A needle tube, wherein a liquid inlet cavity is formed inside the needle tube, and both sides of the liquid inlet cavity are open;

[0007] A steel ball is rollingly mounted on one side opening of the needle tube, and the steel ball seals the opening on one side of the needle tube;

[0008] A tail plug is sealed and installed at the other side opening of the needle tube, and the tail plug has a liquid injection docking hole, through which it can be docked with an external liquid injection device;

[0009] The spring is installed in the liquid inlet cavity, one end of which is in contact with the tail plug support, and the other end of which is used to push the steel ball out of the needle tube and make the steel ball seal one side opening of the needle tube.

[0010] As a preferred technical solution, it also includes a flow suppression column, which has a flow suppression channel with openings on both sides in the middle. The flow suppression column is slidably installed in the liquid inlet chamber, and one side of the flow suppression column is in contact with a spring for support, and the flow suppression column is pressed toward the steel ball by the spring.

[0011] As a preferred technical solution, one side opening of the needle tube has a limiting constriction, the steel ball is installed in the limiting constriction and the steel ball is restricted from falling out of the needle tube by the limiting constriction.

[0012] As a preferred technical solution, the outer end surface of the tail plug forms a first surface, and the end surface of the needle tube on one side of the tail plug forms a second surface. When the tail plug is sealed into the needle tube, the first surface is flush with the second surface.

[0013] The beneficial effects of the utility model are as follows: the head ball of the utility model is designed to be able to rotate freely 360 degrees, making the coating operation more flexible, covering a wider working area, and reducing the need for position adjustment during operation;

[0014] The utility model realizes complete sealing of liquid in a static state through a built-in spring to prevent leakage of liquid when not in operation; when an external force acts on the ball, the spring is compressed and the flow-restricting column moves accordingly, allowing the liquid to flow out in a controlled manner.

[0021] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0022] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0023] like Figure 1-Figure 3 As shown, a universal contact-type liquid-guiding and flow-suppressing spring needle of the utility model comprises a needle tube 2, a liquid inlet cavity is formed inside the needle tube 2, and both sides of the liquid inlet cavity are open;

[0024] It also includes a steel ball 1, which is rollingly mounted on one side opening of the needle tube 2, and the steel ball 1 seals the opening on one side of the needle tube 2;

[0025] and a tail plug 5, which is sealed and installed at the opening on the other side of the needle tube 2. The tail plug 5 has a liquid injection docking hole, which is connected to an external liquid injection device through the liquid injection docking hole. When in use, the external liquid injection device injects liquid into each spring needle to make it enter the liquid inlet cavity. As the steel ball 1 rolls, the liquid can be applied;

[0026] It also includes a spring installed in the liquid inlet cavity, one end of which is in supporting contact with the tail plug 5, and the other end of which is used to push the steel ball 1 out of the needle tube 2 and make the steel ball 1 seal one side opening of the needle tube 2.

[0027] It also includes a flow suppression column, which has a flow suppression channel with openings on both sides in the middle. The flow suppression column is slidably installed in the liquid inlet chamber, and one side of the flow suppression column is in contact with a spring for support, and the flow suppression column is pressed toward the steel ball 1 through the spring.

[0028] Among them, one side opening of the needle tube 2 has a limiting constriction, and the steel ball 1 is installed in the limiting constriction and is restricted from falling out of the needle tube 2 by the limiting constriction. When the steel ball 1 is installed in the limiting constriction, only a bare part is exposed. Therefore, when in use, the steel ball 1 can be squeezed to shrink it and complete the liquid discharge.

[0029] Among them, Figure 1 As shown, the outer end surface of the tail plug 5 forms a first surface 3, and the end surface of the needle tube 2 located on one side of the tail plug 5 forms a second surface 4. When the tail plug 5 is sealed and installed in the needle tube 2, the first surface 3 is flush with the second surface 4.

[0030] Under the action of the spring force and without the application of external force, the utility model can prevent the liquid from flowing out freely. When the ball at the head is subjected to external force, the liquid can be evenly adhered to the surface of the ball at 360 degrees and evenly coated, and the liquid outflow can be effectively controlled to prevent all the excess liquid from flowing out.

[0031] The head ball of the utility model is designed to be able to rotate freely 360 degrees, making the coating operation more flexible, covering a wider working area, and reducing the need for position adjustment during operation;

[0032] The utility model realizes complete sealing of liquid in a static state through a built-in spring to prevent leakage of liquid when not in operation; when an external force acts on the ball, the spring is compressed and the flow-restricting column moves accordingly, allowing the liquid to flow out in a controlled manner.

[0033] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
