Description

Technical Field

[0001] This application relates to the field of micro-pressure irrigation device technology, and more specifically, to a portable micro-pressure irrigation device for injecting plant vascular bundles. Background Technology

[0002] Vascular bundles are the tissues within plants responsible for transporting water and nutrients. They consist of xylem and vessels, with xylem primarily responsible for transporting water and vessels primarily responsible for transporting nutrients. Working together, they maintain the plant's nutrient balance. By injecting biological agents containing hormones and other substances that promote plant growth into the vascular bundles using an infusion device, weakened or damaged vascular bundle tissues can be repaired, rapidly restoring the plant's growth capacity and enhancing its tolerance. Existing infusion devices are mostly disposable, simple syringes. When injecting into the vascular bundles of multiple plants, a large number of infusion devices and storage containers for the biological agents are required, resulting in poor portability. Furthermore, each injection requires manually drawing the biological agent from the storage container before injecting it into the plant's vascular bundles, leading to low injection efficiency. Therefore, we propose a portable micro-pressure infusion device for injecting plant vascular bundles. Utility Model Content

[0003] 1. Technical problems to be solved

[0004] The purpose of this application is to provide a portable micro-pressure infusion device for injecting plant vascular bundles, which solves the technical problems mentioned in the background art. This device features a detachable reservoir, a highly portable and flexible overall design, and allows for complete infusion of plant vascular bundles by holding and releasing the pressure lever. It also enables the infusion device to automatically draw biological agent from the reservoir. By repeating these actions, multiple plants can be injected into the vascular bundles. This eliminates the need for repeated manual drawing of biological agent in traditional micro-pressure infusion devices, significantly improving injection efficiency. Furthermore, the volume of biological agent drawn into the device in a single injection can be quickly adjusted by rotating the adjusting nut, allowing for adjustment of the amount of biological agent injected each time. This device is convenient to use and highly practical.

[0005] 2. Technical Solution

[0006] This application provides a portable micro-pressure infusion device for injecting plant vascular bundles, comprising: an infusion device cylinder and a piston rod slidably inserted into the infusion device cylinder. Two one-way valve tubes are fixedly sleeved at the end of the infusion device cylinder. The one-way valve tubes are respectively threaded to an infusion needle and a liquid storage tank. A lead screw is fixedly connected to the piston rod. A pressure gripper is connected between the infusion device cylinder and the lead screw.

[0007] The pressure grip includes a first L-shaped grip and a second L-shaped grip, which are slidably inserted and connected, and a second spring is fixedly connected between the first L-shaped grip and the second L-shaped grip. The first L-shaped grip is detachably limited to the injector cylinder, and the second L-shaped grip is threadedly connected to the lead screw through a threaded structure.

[0008] By adopting the above technical solution, a micro-pressure infuser is composed of an infuser cylinder and a piston rod. The injection end of the infuser cylinder is equipped with two one-way valve tubes for threaded installation of the infuser needle and the reservoir, respectively. A gripper is connected between the piston rod and the infuser cylinder, consisting of a first L-shaped grip and a second L-shaped grip. Because the first and second L-shaped grips are slidably inserted and fixedly connected to a second spring, gripping the first and second L-shaped grips causes relative displacement between the piston rod and the infuser cylinder. By pre-adding a plant-growth-friendly biological agent to the reservoir, when the piston rod is pulled outwards along the infuser cylinder, the biological agent in the reservoir is drawn into the infuser unidirectionally through the corresponding one-way valve tube. When the gripper is held, the piston rod inserts inward along the cylinder of the infuser, allowing the biological agent inside the cylinder to be delivered unidirectionally to the infuser needle via another one-way valve. The infuser needle then injects the biological agent into the vascular bundles of the plant. This micro-pressure infuser uses a reservoir to pre-store the biological agent. By gripping and releasing the gripper, the biological agent in the reservoir is drawn unidirectionally into the cylinder of the infuser, and then unidirectionally infuses the plant's vascular bundles through the infuser needle in one inflation cycle. Repeated actions allow for the injection of biological agents into the vascular bundles of multiple plants. This eliminates the need for repeated manual suction of biological agents required in traditional micro-pressure infusers when injecting multiple plants, significantly improving injection efficiency. It is also convenient and highly portable.

[0009] Optionally, the outer surface of the injector cylinder is provided with scale lines, the injector cylinder is threaded with an end cap, and the piston rod moves through the end cap.

[0010] By adopting the above technical solution, the infusion device cylinder is a transparent cylinder structure. The volume of the internal biological agent can be observed by setting scale lines. The infusion device cylinder is equipped with an end cap. By removing the end cap, the piston rod can be easily pulled out, which facilitates disassembly and assembly.

[0011] Optionally, the one-way valve tube includes a tube body, which is fixedly sleeved with the injector cylinder. A valve cavity is provided inside the tube body, and a sealing ball and a first spring are provided inside the valve cavity.

[0012] By adopting the above technical solution, a one-way valve structure can be formed by the sealing ball and the first spring installed in the valve cavity inside the tube. Its one-way flow channel setting allows the injector cylinder to draw in the biological agent in the storage tank when the piston rod is pulled outward. When the piston rod is inserted inward, the one-way valve pipe connected to the storage tank is closed in one direction, and the biological agent in the injector cylinder will not be injected back into the storage tank, but will be injected out one-way from the injecting needle.

[0013] Optionally, the outer surface of each tube is provided with an external threaded groove, the end of the injection needle is provided with a threaded sleeve for threaded connection with one tube, and the bottom of the liquid storage tank is fixedly fitted with a connecting joint for threaded connection with another tube.

[0014] By adopting the above technical solution, both the injection needle and the liquid storage tank are fixedly connected to the corresponding tube body through a threaded structure, which facilitates the disassembly and assembly work.

[0015] Optionally, the liquid storage tank is made of transparent plastic, and a replenishment cap is threaded onto the liquid storage tank.

[0016] By adopting the above technical solution, the liquid storage tank with a transparent structure can be easily observed to observe the remaining amount of biological agent inside, thus facilitating the replenishment operation through the replenishment cap.

[0017] Optionally, the first L-shaped handle is fixedly connected to a first collar, and a retaining ring is fixedly sleeved on the outer surface of the end of the infuser cylinder away from the infuser needle. The first collar is limited and installed between the retaining ring and the end cap. The second L-shaped handle is fixedly connected to a second collar, and the second collar is rotatably connected to an adjusting nut. The second collar is movably sleeved on the outside of the lead screw, and the adjusting nut is threadedly sleeved with the lead screw.

[0018] By adopting the above technical solution, the first L-shaped grip and the second L-shaped grip are connected by a second spring elastic insertion. The first sleeve connected to the first L-shaped grip is limited and installed between the retaining ring and the end cap, while the second sleeve connected to the second L-shaped grip is movably sleeved on the outside of the screw rod. It is threadedly connected to the screw rod by an adjusting nut. By rotating the adjusting nut, the relative position of the piston rod and the infuser cylinder can be adjusted. Thus, by adjusting the insertion stroke of the first L-shaped grip and the second L-shaped grip, the capacity of the biological agent inhaled by the infuser cylinder in a single injection can be adjusted, thereby achieving the purpose of adjusting the capacity of the biological agent infused each time.

[0019] 3. Beneficial effects

[0020] The technical solutions provided in this application, including one or more, have at least the following technical effects or advantages: the micro-pressure infuser has a detachable storage tank, and its overall design structure is highly portable and flexible in use. By holding and releasing the pressure gripper, one plant vascular bundle infusion operation can be completed, and the infuser cylinder can automatically draw biological agent from the storage tank. By repeating the above actions, multiple plant vascular bundles can be injected, solving the problem of repeatedly manually drawing biological agent during the injection of multiple plant vascular bundles using traditional micro-pressure infusers, greatly improving injection efficiency. Furthermore, by rotating the adjusting nut, the volume of biological agent drawn into the infuser cylinder per injection can be quickly adjusted, achieving the purpose of adjusting the volume of biological agent injected each time. It is convenient to use and highly practical. Attached Figure Description

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] Reference Figures 1 to 4This application provides a portable micro-pressure infusion device for injecting plant vascular bundles, comprising: an infusion device body 1 and a piston rod 5 slidably inserted into the infusion device body 1. Two one-way valve tubes 2 are fixedly sleeved at the end of the infusion device body 1. The one-way valve tubes 2 are respectively threaded to an infusion needle 3 and a liquid storage tank 4. The piston rod 5 is fixedly connected to a lead screw 51. A pressure gripper 6 is connected between the infusion device body 1 and the lead screw 51.

[0028] The pressure-gripping device 6 includes a first L-shaped grip 61 and a second L-shaped grip 62, which are slidably connected together. A second spring 63 is fixedly connected between the first L-shaped grip 61 and the second L-shaped grip 62. The first L-shaped grip 61 is detachably and limit-connected to the infuser cylinder 1, and the second L-shaped grip 62 is threadedly connected to the lead screw 51. The infuser cylinder 1 and the piston rod 5 together form a micro-pressure infuser. The injection end of the infuser cylinder 1 is simultaneously provided with two... A one-way valve tube 2 is used to thread-install the infusion needle 3 and the reservoir 4 respectively. A gripper 6 is connected between the piston rod 5, the screw 51 fixedly connected to it, and the infusion cylinder 1. The gripper 6 consists of a first L-shaped grip 61 and a second L-shaped grip 62. Because the first L-shaped grip 61 and the second L-shaped grip 62 are slidably inserted and fixedly connected to a second spring 63, by gripping the first L-shaped grip 61 and the second L-shaped grip 62 and causing them to move in opposite directions, the piston rod 5 and the infusion cylinder 1 can be forced to move relative to each other. The storage tank 4 is pre-filled with a biological agent that promotes plant growth. When the piston rod 5 is pulled outward along the infuser cylinder 1, the biological agent in the storage tank 4 is drawn into the inner cavity of the infuser cylinder 1 through the corresponding one-way valve tube 2. When the gripper 6 is held, the piston rod 5 is inserted inward along the infuser cylinder 1, allowing the biological agent in the inner cavity of the infuser cylinder 1 to be delivered unidirectionally to the infuser needle 3 through another one-way valve tube 2. The infuser needle 3 then performs the function of injecting the biological agent into the plant's vascular bundles. This micro-pressure infuser... By pre-storing biological agents in the storage tank 4, the biological agents in the storage tank 4 can be drawn into the inner cavity of the infuser cylinder 1 by holding and releasing the pressure gripper 6. The infuser needle 3 then performs one inflation stroke of the plant vascular bundle. By repeating the action, multiple plants can be injected into their vascular bundles. This solves the problem of repeatedly manually drawing biological agents when injecting multiple plants into their vascular bundles using traditional micro-pressure infusers, greatly improving injection efficiency, making it convenient to use and highly portable.

[0029] Reference Figure 1 and Figure 2The outer surface of the infusion device cylinder 1 is provided with scale lines 11. The end cap 13 is threaded onto the infusion device cylinder 1. The piston rod 5 moves through the end cap 13. The infusion device cylinder 1 has a transparent cylinder structure. The volume of the internal biological agent can be observed by setting the scale lines 11. The piston rod 5 can be easily pulled out by setting the end cap 13, which facilitates disassembly and assembly.

[0030] Reference Figure 1 and Figure 4 The one-way valve tube 2 includes a tube body 21, which is fixedly sleeved with the infuser cylinder 1. A valve chamber 211 is provided inside the tube body 21. A sealing ball 22 and a first spring 23 are provided inside the valve chamber 211. The sealing ball 22 and the first spring 23 installed in the valve chamber 211 can form a one-way valve structure. Its one-way flow channel is set so that when the piston rod 5 is pulled outward, the infuser cylinder 1 can draw the biological agent in the storage tank 4. When the piston rod 5 is inserted inward, the one-way valve tube 2 connected to the storage tank 4 is closed in one direction. The biological agent in the infuser cylinder 1 will not be injected back into the storage tank 4, but will be injected out one-way from the infuser needle 3.

[0031] Reference Figure 1 and Figure 4 The outer surface of each tube body 21 is provided with an external threaded groove 212. The end of the injection needle 3 is provided with a threaded sleeve for threaded connection with one tube body 21. The bottom of the liquid storage tank 4 is fixedly sleeved with a connecting joint 42 for threaded connection with another tube body 21. Both the injection needle 3 and the liquid storage tank 4 are threadedly fixedly connected to the corresponding tube body 21 through a threaded structure, which facilitates the disassembly and assembly work.

[0032] Reference Figure 1 and Figure 2 The storage tank 4 is made of transparent plastic. A replenishment cap 41 is threaded onto the storage tank 4. The transparent structure of the storage tank 4 allows for easy observation of the remaining amount of biological agent inside, thus facilitating replenishment operations through the replenishment cap 41.

[0033] Reference Figure 2 and Figure 3The first L-shaped grip 61 is fixedly connected to a first collar 611. A retaining ring 12 is fixedly sleeved on the outer surface of the end of the infuser cylinder 1 away from the infuser needle 3. The first collar 611 is limited and installed between the retaining ring 12 and the end cap 13. The second L-shaped grip 62 is fixedly connected to a second collar 621. The second collar 621 is rotatably connected to an adjusting nut 622. The second collar 621 is movably sleeved on the outside of the lead screw 51, and the adjusting nut 622 is threadedly engaged with the lead screw 51. The first L-shaped grip 61 and the second L-shaped grip 62 are elastically connected by a second spring 63. The first L-shaped handle 61 is connected to the first ring 611, which is limited and installed between the retaining ring 12 and the end cap 13. The second L-shaped handle 62 is connected to the second ring 621, which is movably sleeved on the outside of the lead screw 51. The adjusting nut 622 is threadedly connected to the lead screw 51. By rotating the adjusting nut 622, the relative position of the piston rod 5 and the infuser cylinder 1 can be adjusted. Thus, by adjusting the insertion stroke of the first L-shaped handle 61 and the second L-shaped handle 62, the capacity of the biological agent inhaled by the infuser cylinder 1 in a single injection can be adjusted, thereby achieving the purpose of adjusting the capacity of the biological agent infused each time.

[0034] Working principle: During assembly, the piston rod 5 is inserted into the injector cylinder 1. The first collar 611 and the end cap 13 are both inserted movably from the end of the screw rod 51. The end cap 13 is threadedly connected to the injector cylinder 1, which limits the installation of the first collar 611 between the retaining ring 12 and the end cap 13. The second collar 621 is inserted from the end of the screw rod 51 and is threadedly connected to the screw rod 51 by the adjusting nut 622. Under the action of the second spring 63, the first L-shaped grip 61 and the second L-shaped grip 621 are engaged. The handle 62 slides into place, and when the gripper 6 is released, the first L-shaped handle 61 and the second L-shaped handle 62 automatically reset. The injection end of the infuser cylinder 1 is threadedly connected to the infuser needle 3 and the reservoir 4 via two one-way valve tubes 2. By gripping the first L-shaped handle 61 and the second L-shaped handle 62 and moving them in opposite directions, the piston rod 5 is forced to move relative to the infuser cylinder 1. When the piston rod 5 is pulled outward along the infuser cylinder 1, the biological agent in the reservoir 4 is used to... The corresponding one-way valve tube 2 draws the biological agent into the inner cavity of the infuser cylinder 1 in one direction. When the gripper 6 is held, the piston rod 5 is inserted inward along the infuser cylinder 1, allowing the biological agent in the inner cavity of the infuser cylinder 1 to be delivered unidirectionally to the infuser needle 3 through another one-way valve tube 2. Then, the infuser needle 3 is used to realize the function of injecting biological agent into the vascular bundles of plants. By repeatedly holding and releasing the action, the vascular bundles of multiple plants can be injected, which solves the problem of repeatedly manually drawing biological agent in the process of injecting biological agent into the vascular bundles of multiple plants in the traditional micro-pressure infuser, greatly improving the injection efficiency. In addition, by using the adjusting nut 622 to be threadedly connected to the lead screw 51, the relative position of the piston rod 5 and the infuser cylinder 1 can be adjusted by rotating the adjusting nut 622. Thus, by adjusting the insertion stroke of the first L-shaped grip 61 and the second L-shaped grip 62, the capacity of biological agent drawn into the infuser cylinder 1 in a single injection can be adjusted, realizing the purpose of adjusting the capacity of biological agent injected each time. It is convenient to use and highly portable.
