Description

Technical Field

[0001] This utility model belongs to the field of chemical equipment, and specifically relates to a plant infusion needle and infusion device. Background Technology

[0002] With urbanization, greening has gradually become an important part of urban construction. To promote better plant growth, attaching plant infusion devices to plants for sap infusion has also become an important method of plant care. Plant infusion is suitable for restoring the vitality of transplanted large trees, improving survival rates, and revitalizing old, weak, diseased, and ancient trees. It can also be used for fruit trees and vegetables to control pests, prevent and treat diseases, and supplement water and nutrients to increase yields and income.

[0003] Plant infusion involves directly delivering liquids (such as nutrient solutions, medications, and growth regulators) into the xylem or phloem of a plant. This requires inserting an infusion needle into the plant's branches or roots. Sometimes, it's necessary to control the infusion process by administering the same liquid to the same part of the plant at different times, such as three times a day. Other times, it's necessary to administer the liquid to different parts of the plant, such as different diseased sections of the same plant. This necessitates stopping the infusion during the process to prevent waste and to precisely control the delivery of the liquid to the plant.

[0004] Therefore, it is necessary to design a plant infusion needle and infusion device. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a plant infusion needle and infusion device to improve the problem that the needle cannot stop the infusion process of the current plant infusion needle.

[0006] To achieve the above and other related objectives, this utility model proposes a plant-based infusion needle, comprising:

[0007] The needle body includes a hollow structure, with an inlet on one side and an infusion port on the other side, and the inlet is connected to an infusion tube.

[0008] A liquid-stopping part is used to clamp the infusion tube;

[0009] The gripping part is a flat structure formed by extending the needle body between the inlet and the outlet.

[0010] In one embodiment of the present invention, the liquid-stopping part is located on the side of the needle body near the liquid inlet and includes at least one clamping groove.

[0011] In one embodiment of the present invention, one end of each clamping groove is close to the liquid inlet, and the other end is away from the liquid inlet and gradually expands to form a V-shaped opening.

[0012] In one embodiment of this utility model, the hollow structure is cylindrical, and the slotting direction of each of the clamping grooves is parallel to the axial direction of the hollow structure.

[0013] In one embodiment of the present invention, the gripping part includes at least one plate, and the hollow structure passes through the plate, such that the liquid inlet and the liquid outlet of the hollow structure are located on opposite sides of the gripping part.

[0014] In one embodiment of the present invention, at least one reinforcing rib is provided between the plate and the hollow structure, and one side of each reinforcing rib protrudes from the surface of the plate, and the protruding part is used to enhance the friction coefficient of the gripping part.

[0015] In one embodiment of this utility model, the inlet is flush with one side edge of the plate, and the outlet extends horizontally beyond the other side edge of the plate.

[0016] In one embodiment of this utility model, the liquid-stopping part is formed by horizontally extending the plate on the side near the liquid inlet, and the liquid-stopping part is provided with reinforcing ribs.

[0017] In one embodiment of the present invention, the gripping part includes two plates, which are arranged in parallel with a gap between them. The hollow structure is sandwiched between the two plates, and a reinforcing connecting rib is provided between the two plates. The two sides of the reinforcing connecting rib protrude from the two distant sides of the two plates, and the protruding part is used to increase the friction coefficient of the gripping part.

[0018] To achieve the above-mentioned objectives and other related objectives, this utility model also proposes a plant infusion device, including the aforementioned plant infusion needle.

[0019] This invention discloses a plant infusion needle and infusion device, comprising a needle body, a stop-flow portion, and a gripping portion. The needle body has a hollow structure with an inlet on one side and an infusion port on the other side, the inlet being connected to an infusion tube. The stop-flow portion is used to clamp the infusion tube. The gripping portion is a flat structure formed by extending the needle body between the inlet and infusion ports. When infusing a plant, the inlet is connected to the infusion tube, which is connected to an infusion bottle or bag. Holding the gripping portion, the infusion port is inserted into the xylem or phloem of the plant for infusion. When the infusion tube is clamped at the stop-flow portion, the infusion tube has no flow capability, and infusion to the plant is stopped. When the infusion tube is removed from the stop-flow portion, the infusion tube is unobstructed, and infusion to the plant resumes. Therefore, this invention achieves rapid clamping / releasing of the infusion tube, solving the problem of requiring an additional stop clamp in traditional infusion methods. The plant infusion needle and device can control infusion to the same part of the plant at different times as needed, or control infusion to different parts of the plant at the same time. This greatly expands the application range and function of the plant infusion needle, allowing for more precise control of infusion to the plant. Attached Figure Description

[0027] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0028] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0029] Please see Figures 1-5 As shown, this utility model proposes a plant infusion needle, including a needle body 10, a stop-flow portion 20, and a gripping portion 30. The needle body 10 includes a hollow structure, with an inlet 11 on one side and an infusion port 12 on the other side, and the inlet 11 is connected to an infusion tube; the stop-flow portion 20 is used to clamp the infusion tube; the gripping portion 30 is a flat structure formed by extending the needle body 10 between the inlet 11 and the infusion port 12.

[0030] It should be noted that the integrated design of the needle body 10, the fluid-stopping part 20, and the gripping part 30, and the use of injection molding, reduces additional components, facilitates mass production, lowers assembly complexity and cost, and improves reliability. The fluid-stopping part 20 can quickly clamp or release the infusion tubing, achieving immediate fluid cessation or resumption of infusion, meeting the precise infusion needs at different times and locations. The gripping part 30 is a flat structure formed by extending the needle body 10 between the inlet 11 and the infusion port 12. This flat structure facilitates the application of force to pierce the xylem or phloem of the plant, while also enhancing operational stability.

[0031] In one embodiment of this invention, the liquid-stopping part 20 is located on the side of the needle body 10 near the liquid inlet 11 and includes at least one clamping groove 21. One end of each clamping groove 21 is close to the liquid inlet 11, and the other end is away from the liquid inlet 11 and gradually expands to form a V-shaped opening. The hollow structure of the needle body 10 is cylindrical, and the opening direction of each clamping groove 21 is parallel to the axial direction of the hollow structure.

[0032] It should be noted that the V-shaped groove 21 can be made of a plastic with a certain degree of elasticity (such as PP or TPE) to ensure that the groove 21 can be repeatedly opened and closed without easily breaking.

[0033] It should be noted that the V-shaped clamping groove 21 of the stop-flow part 20 is designed to gradually clamp the infusion tube during insertion, preventing sudden jamming or slippage and achieving stable and adjustable flow control. At the same time, the V-shaped clamping groove 21 can also accommodate infusion tubes of different diameters, improving the versatility of the device.

[0034] Since the clamping groove 21 is close to the inlet 11, the operator can easily press or release the infusion tube with his thumb or forefinger while holding the needle body 10, which improves the efficiency of operation. Moreover, the clamping groove 21 is axially parallel to the hollow structure of the needle body 10, which avoids weakening the overall strength of the needle body and does not affect the liquid flow path.

[0035] In one embodiment of the present invention, the gripping part 30 includes at least one plate 31, and a hollow structure passes through the plate 31, such that the liquid inlet 11 and the liquid outlet 12 of the hollow structure are located on opposite sides of the gripping part 30.

[0036] It should be noted that the hollow structure passes directly through the plate 31, ensuring that the liquid flows directly from the inlet 11 to the outlet 12 without any detours, reducing the risk of blockage. The integrated design of the plate 31 and the needle body 10 avoids additional assembly components and reduces the risk of leakage.

[0037] In one embodiment of the present invention, at least one reinforcing connecting rib 32 is provided between the plate 31 and the hollow structure. One side of each reinforcing connecting rib 32 protrudes from the surface of the plate 31, and the protruding part is used to enhance the friction coefficient of the gripping part 30.

[0038] It should be noted that the reinforcing connecting rib 32 forms a supporting structure between the plate 31 and the hollow needle body 10, significantly improving the overall strength of the gripping part 30 and preventing bending or breakage when piercing plants. The protruding design of the reinforcing connecting rib 32 can disperse torsional stress during operation, preventing loosening or deformation at the connection between the needle body 10 and the gripping part 30. Moreover, the protruding part forms an anti-slip texture, enhancing grip friction and ensuring stable grip even in humid environments (such as sap or pesticide contamination).

[0039] In one embodiment of the present invention, the inlet 11 and one side edge of the plate 31 are flush, and the inlet 12 extends horizontally out of the other side edge of the plate 31.

[0040] It should be noted that the horizontal extension of the infusion port 12 beyond the other edge of the plate 31 ensures that the infusion port 12 can be inserted into the plant during infusion. The part of the infusion port 12 that extends horizontally beyond the other edge of the plate 31 can be conical to facilitate insertion into the plant. Alternatively, a needle made of a hard material can be inserted into the infusion port 12.

[0041] In one embodiment of the present invention, the liquid-stopping part 20 is formed by horizontally extending the plate 31 on the side near the liquid inlet 11, and the liquid-stopping part 20 is provided with reinforcing ribs.

[0042] It should be noted that the liquid-stopping part 20 is formed by the horizontal extension of the plate 31, forming an integral structure with the gripping part 30, avoiding additional assembly parts and improving the overall structural strength and reliability. The reinforcing ribs on the liquid-stopping part 20 further increase its rigidity, preventing deformation or breakage during repeated clamping operations and extending its service life.

[0043] In one embodiment of the present invention, the gripping part 30 includes two plates 31, which are arranged in parallel with a gap between them. A hollow structure is sandwiched between the two plates 31, and a reinforcing connecting rib 32 is provided between the two plates 31. The two sides of the reinforcing connecting rib 32 protrude from the two far apart sides of the two plates 31, and the protruding part is used to increase the friction coefficient of the gripping part 30.

[0044] It should be noted that the two plates 31 arranged in parallel intervals form a stable clamping frame, which provides bidirectional support to the hollow needle body, improves its bending resistance, and the reinforcing connecting ribs 32 form a three-dimensional support network between the two plates 31, effectively resisting the combined stress (such as axial pressure + torsional force) during puncture.

[0045] To achieve the above-mentioned objectives and other related objectives, this utility model also proposes a plant infusion device, including the aforementioned plant infusion needle 1.

[0046] It should be noted that the plant infusion needle 1 includes a needle body 10, a stop-flow portion 20, and a gripping portion 30. The needle body 10 has a hollow structure, with an inlet 11 on one side and an infusion port 12 on the other side, and the inlet 11 is connected to an infusion tube; the stop-flow portion 20 is used to clamp the infusion tube; the gripping portion 30 is a flat structure formed by extending the needle body 10 between the inlet 11 and the infusion port 12. The infusion bag or infusion bottle can be connected to several infusion tubes, and each infusion tube is equipped with a plant infusion needle 1.

[0047] Therefore, this invention achieves rapid clamping / releasing of the infusion tube, solving the problem of requiring an additional stop clamp in traditional infusion methods. The plant infusion needle and device can control infusion to the same part of the plant at different times as needed, or control infusion to different parts of the plant at the same time. This greatly expands the application range and function of the plant infusion needle, allowing for more precise control of infusion to the plant.
