Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of gardening equipment and relates to a high-pressure anti-leakage switch for a tree and plant infusion device. Background Art
[0002] In the field of gardening, in order to achieve the purpose of increasing production and income, it is necessary to supplement water and nutrients to trees and plants. When performing infusion, a plant and tree infusion device is required, and the device is inserted into the root system or branches of trees, plants, and fruit trees for infusion.
[0003] At present, the tree and plant infusion device on the market consists of a bottle cap, a plastic tube, a joint, a flow regulating component, and an infusion needle. When quickly infusing a tree or plant, it is necessary to pour the liquid into the container in advance, tighten the bottle cap, and fill the infusion device with 300Kpa-400Kpa air pressure to make the liquid flow into the tree or plant. The flow regulating component used in the tree and plant infusion device is generally a pulley-type flow regulator.
[0004] The disadvantage is that when infusing trees and plants, the plastic tube needs to be thickened and hardened to withstand high pressure, but the pulley-type flow regulator has limited pressure on the plastic tube and is generally only suitable for soft plastic tubes, and it is difficult to use thickened and hardened plastic tubes. Therefore, some infusion devices that have been inflated at the site or at home are taken to the forest to infuse trees and plants. Because the pulley-type flow regulator cannot effectively flatten the thickened and hardened plastic tube, gas leakage occurs, which brings great inconvenience to the infusion work. In addition, workers need to frequently push the pulley to close the flow regulator, which will cause hand fatigue or even injury when working for a long time. Utility Model Content

DETAILED DESCRIPTION
[0027] The present invention will be further described below with reference to the accompanying drawings. Figure 1-7 :
[0028] A high-pressure anti-leakage switch for a tree and plant infusion device, the tree and plant infusion device comprising a bottle cap 11, an infusion tube 12 and an infusion needle 13, the infusion tube 12 being a flexible tube and connecting the bottle cap 11 and the infusion needle 13, the high-pressure anti-leakage switch comprising a water-stop clip 20 sleeved on the infusion tube 12, the water-stop clip 20 being provided with a reducing groove 21 for the infusion tube 12 to pass through, the reducing groove 21 having a water-stop end 211 and a water-passing end 212, the width of the water-stop end 211 being no greater than the thickness of the infusion tube 12 when it is pressed against the inner wall, and the width of the water-passing end 212 being no less than the outer diameter of the infusion tube 12.
[0029] The usage of this embodiment is: when inflating or transporting, the infusion tube 12 is pushed to the water-stopping end 211, and the diameter-changing groove 21 squeezes the infusion tube 12, so that it is flattened until the inner wall abuts against it, thereby closing the internal channel of the infusion tube 12 to prevent leakage. If the width of the water-stopping end 211 is smaller than the thickness of the infusion tube 12 when it is pressed against the inner wall (the thickness when the inner wall abuts against each other is roughly equivalent to twice the thickness of the wall of the infusion tube 12), the diameter-changing groove 21 will continue to squeeze the infusion tube 12, causing it to deform, and the water-stopping effect is better. When infusion is needed, the infusion tube 12 is pushed to the water-passing end 212, and the squeezing of the infusion tube 12 by the diameter-changing groove 21 disappears, and the infusion tube 12 resumes the infusion function.
[0030] Compare with Figure 3 In this embodiment, the variable diameter through groove 21 includes a large hole 213 and a wedge-shaped slit 214. The large hole 213 forms a water passing end 212, and the wedge-shaped slit 214 gradually narrows from the large hole 213 to the other end to form a water stopping end 211. Preferably, the large hole 213 is a circular hole 31 structure.
[0031] Compare with Figure 2 and attached Figure 3 As the first type of water-stop clip 20 of this embodiment, the variable diameter through groove 21 is a closed groove. The water-stop clip 20 with this structure has a simpler structure and lower cost.
[0032] Compare with Figure 4 and attached Figure 5 As the second water-stop clip 20 of this embodiment, the variable diameter through groove 21 is an open groove, the open end 215 of the variable diameter through groove 21 is connected to the water-passing end 212, and the water-stop clip 20 is connected to a fixing plate 22 that closes the open end 215.
[0033] Furthermore, in this embodiment, the fixing structure of the fixing plate 22 is: fixing plungers 23 are provided on both sides of the open end 215, and the fixing plate 22 is provided with fixing holes 24 that are clamped and fixed with the fixing plungers 23. The water-stop clip 20 is inserted into the infusion tube 12 through the open end 215 of the variable diameter through groove 21, and then the fixing plate 22 is fixed to the water-stop clip 20, and the open end 215 is closed.
[0034] Compare with Figure 1 and attached Figure 6 In order to achieve better high-pressure resistance and leakage prevention, the high-pressure leakage prevention switch further includes a needle cap 30 sleeved on the outer end of the infusion needle 13, and the needle cap 30 is provided with a circular hole 31 that matches the outer diameter of the infusion needle 13 and seals the infusion needle 13. Further, the circular hole 31 is a blind hole structure, which is provided at one end of the needle cap 30. When high-pressure leakage prevention is required, the needle cap 30 is sleeved on the outer end of the infusion needle 13 to seal the infusion needle 13, thereby playing a double-layer leakage prevention role.
[0035] In order to store the needle cap 30 and prevent it from being lost, a hanging clip 32 is provided on one side of the needle cap 30. The hole diameter of the hanging clip 32 matches the outer diameter of the infusion tube 12, and the needle cap 30 can be hung on the infusion tube 12. Preferably, the hanging clip 32 is a semicircular structure, and the opening of the hanging clip 32 is smaller than the outer diameter of the infusion tube 12. When the hanging clip 32 is inserted into the infusion tube 12, it can be prevented from being detached from the infusion tube 12.
[0036] Compare with Figure 7 This embodiment also provides another storage structure: a hanging plunger 25 is provided on the water-stop clip 20 , the outer diameter of the hanging plunger 25 matches the aperture of the circular hole 31 , and the needle cap 30 can be hung on the water-stop clip 20 .
[0037] Compare with Figure 1 The bottle cap 11 is connected to two infusion tubes 12, each of which is provided with an infusion needle 13, a water-stop clip 20 and a needle cap 30. Each infusion tube 12 can be independently controlled by the water-stop clip 20 and the needle cap 30.
[0038] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
