DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0040] Because the relevant technology puts pesticides, fungicides, attractants and nutrients into an infusion bag, flocculation, precipitation, stratification and even chemical reactions may occur after being left for a long time, resulting in technical problems such as clogging the infusion tube and even causing pesticide damage.

[0041] See also Figure 1-3 In order to solve the above technical problems, the present application proposes a multi-channel infusion device, including a plurality of infusion bags 10, a mixing container 20, a plurality of first infusion pipelines 30 and a plurality of second infusion pipelines 40.

[0042] Different infusion bags 10 can be used to store different medicines, such as pesticides, fungicides, attractants and nutrients, etc., that is, the type and quantity of medicines in each infusion bag 10 can be adjusted as needed to adapt to the needs and growth environment of different fruit trees or plants.

[0043] The mixing container 20 is formed with a mixing chamber 20a, and the mixing container 20 is provided with multiple liquid inlets 20b and multiple liquid outlets 20c connected to the mixing chamber 20a; multiple first infusion pipes 30 are connected to the multiple infusion bags 10 one-to-one, and the other ends of the multiple first infusion pipes 30 are connected to the liquid inlet 20b; multiple second infusion pipes 40 are respectively connected to different liquid outlets 20c one-to-one, and the other ends of the second infusion pipes 40 are connected to the infusion needles 50.

[0044] In the specific implementation stage, the medicines in different infusion bags 10 are transported to the mixing container 20 through the corresponding first infusion pipe 30. After being mixed in the mixing container 20, the infusion needle 50 is then transported through the second infusion pipe 40, and the user can insert the infusion needle into the fruit tree or plant according to the required infusion position.

[0045] In this embodiment, since the medicines in different infusion bags 10 are mixed only when the infusion is carried out, and after the mixing is completed, they are quickly transported to the fruit trees or plants through the second infusion pipe 40 and the infusion needle 50, the mixed medicines will not be left for a long time, thus avoiding flocculation, precipitation, stratification and even chemical reactions, thereby preventing the infusion tube from being blocked and causing drug damage.

[0046] It is understandable that the amount of liquid medicine absorbed by the same position of a fruit tree or other plant is limited. Therefore, in this embodiment, multiple second infusion pipes 40 are designed to simultaneously infuse liquid to multiple locations of the fruit tree or plant according to the growth conditions of the fruit tree or plant, which can effectively improve the infusion efficiency.

[0047] In addition, in this embodiment, the length of the second infusion pipe 40 generally does not exceed 15 cm. By limiting the length, the mixed liquid in the mixing chamber 20a flows in the second infusion pipe 40 for a shorter time, ensuring that the mixed liquid is quickly delivered to the fruit trees or plants through the second infusion pipe 40 and the infusion needle 50 to meet their growth or treatment needs.

[0048] As for the infusion needle 50 , the shorter length of the second infusion pipeline 40 means a smaller pressure loss, thereby making it easier to push the mixed liquid into the deep tissue of the fruit tree or plant.

[0049] In this example, in order to improve the mixing efficiency of the medicine, a small stirrer can be built into the mixing chamber 20a, and the medicine can be fully mixed through stirring.

[0050] In order to facilitate transportation, in this embodiment, the first infusion pipeline 30 and the mixing container 20 are detachably connected. Figure 2-3 , that is, the mixing container 20 is provided with a plurality of first joint parts 21, the plurality of first joint parts 21 are distributed one by one with the plurality of liquid inlets 20b, a first liquid inlet channel 21a with openings at both ends is formed in the first joint part 21, and the first liquid inlet channel 21a is communicated with the liquid inlet 20b;

[0051] The first liquid infusion pipeline 30 is provided with a first joint fitting portion 31 at one end thereof facing the mixing container 20. A second liquid inlet channel 31a with openings at both ends is formed in the first joint fitting portion 31. The second liquid inlet channel 31a is communicated with the first liquid infusion pipeline 30.

[0052] The first joint matching portion 31 is threadably matched with the first joint portion 21 , so that the second liquid inlet channel 31 a is communicated with the first liquid inlet channel 21 a .

[0053] In this way, during the drug delivery stage, the drug passes through the infusion bag 10, the first infusion pipe 30, the second liquid inlet channel 31a, the first liquid inlet channel 21a and the liquid inlet 20b in sequence, and finally enters the mixing chamber 20a. Through the threaded connection, the first joint part 21 and the first joint mating part 31 can be quickly connected and separated, thereby improving the efficiency of installation and disassembly.

[0054] Please continue reading Figure 2-3 After the infusion bag 10 and the first infusion pipeline 30 are connected and the infusion bag 10 is hung on the tree, if the first infusion pipeline 30 and the first joint matching part 31 are an integrated structure, when the first joint matching part 31 is threadedly connected with the first joint part 21, the first infusion pipeline 30 will be driven to twist, thereby affecting the delivery of the medicine. Therefore, in this embodiment, the first infusion pipeline 30 includes a first infusion pipeline body 32, a first blocking part 33 and a second blocking part 34.

[0055] The first blocking portion 33 is connected to the first infusion pipeline body 32 and protrudes from the first infusion pipeline body 32 in the radial direction of the first infusion pipeline body 32; the second blocking portion 34 is connected to the first infusion pipeline body 32 and is spaced apart from the first blocking portion 33, and the second blocking portion 34 protrudes from the first infusion pipeline body 32 in the radial direction of the first infusion pipeline body 32;

[0056] The first joint matching portion 31 is movably sleeved on the first infusion pipeline body 32 located between the first blocking portion 33 and the second blocking portion 34 .

[0057] In this way, the first blocking portion 33 and the second blocking portion 34 play a certain blocking and limiting role, so that the first joint matching portion 31 can move between the first blocking portion 33 and the second blocking portion 34 without falling off. At the same time, the first joint matching portion 31 can also rotate around the axis of the first infusion pipeline body 32, so that when the first joint matching portion 31 is threadedly connected with the first joint portion 21, the first infusion pipeline 30 will not twist.

[0058] In this embodiment, the first blocking portion 33, the second blocking portion 34 and the first infusion pipeline body 32 are an integrally formed structure, and are preferably made of polypropylene, which has good elasticity and pressure bearing capacity.

[0059] Please continue reading Figure 2-3The first joint matching portion 31 includes a first sleeve portion 311 and a second sleeve portion 312. The first sleeve portion 311 is connected to the first infusion pipeline 30 and protrudes from the first infusion pipeline 30 in the radial direction of the first infusion pipeline 30. The second sleeve portion 312 is fixed relative to the first sleeve portion 311 and has a wall surface facing the first infusion pipeline 30, and the wall surface is formed with a first internal thread 3121; wherein, the first joint portion 21 is formed with a first external thread 211 that matches the first internal thread 3121 on the side away from the first liquid inlet channel 21a.

[0060] When the first joint matching portion 31 is threadedly connected to the first joint portion 21, the first joint portion 21 will extend into the second liquid inlet channel 31a, so the second liquid inlet channel 31a and the first liquid inlet channel 21a will partially overlap, which to a certain extent shortens the delivery distance of the medicine.

[0061] Further, in order to improve the sealing performance, see Figure 3 A sealing ring 3111 is provided on the side of the first sleeve portion 311 facing the second liquid inlet channel 31a. When the first joint portion 21 and the first joint matching portion 31 are threadedly tightened, the sealing ring 3111 fits against the side wall of the first joint portion 21 facing the first liquid inlet channel 21a, thereby reducing the outflow of the medicine through the connection between the first joint matching portion 31 and the first joint portion 21.

[0062] In this embodiment, the sealing ring 3111 and the first fitting portion 311 and the second fitting portion 312 may be an integrally formed structure, for example, may be made of polyethylene material, which has good chemical stability and corrosion resistance.

[0063] See also Figure 4 In order to facilitate the production and transportation of the mixing container 20, the mixing container 20 is provided with a plurality of second joint parts 22, and the plurality of second joint parts 22 are distributed one by one with the plurality of liquid outlets 20c. A first liquid outlet channel 22a with openings at both ends is formed in the second joint part 22, and the first liquid outlet channel 22a is connected with the liquid outlet 20c;

[0064] The second liquid infusion pipeline 40 is provided with a second joint matching portion 41 at one end thereof facing the mixing container 20. A second liquid outlet channel 41a with openings at both ends is formed in the second joint matching portion 41. The second liquid outlet channel 41a is connected to the second liquid infusion pipeline 40.

[0065] The second joint matching portion 41 is threadably matched with the second joint portion 22 so that the second liquid outlet channel 41 a is communicated with the first liquid outlet channel 22 a .

[0066] The second joint portion 22 and the first joint portion 21 can be an integrally formed structure with the mixing container 20, or can be connected together by hot melting or the like, without further restriction herein, and the second joint mating portion 41 can also be an integrally formed structure with the second infusion pipeline 40, thereby ensuring the strength of the connection, and the threaded mating of the second joint mating portion 41 and the second joint portion 22 facilitates quick installation and disassembly of the second infusion pipeline 40 and the mixing container 20.

[0067] It is understandable that the second joint fitting portion 41 is similar in structure to the first joint fitting portion 31 , and therefore, in order to improve sealing, a seal is also provided on the second joint fitting portion 41 , and the principle and function are the same as those of the sealing ring 3111 .

[0068] Following the above, in the form in which the infusion bag 10 and the first infusion pipe 30 are detachably connected, the infusion bag 10 and the first infusion pipe 30 are threadedly connected, which also facilitates the separate processing and manufacturing of the infusion bag 10 and the first infusion pipe 30, and facilitates manufacturing and molding. In addition, the infusion bag 10 in this embodiment is purchased as a product sold on the market, so its specific structure is not elaborated here.

[0069] In order to prevent the mixing container 20 from shaking and reduce the pulling on the first infusion pipe 30, a mounting frame 60 is provided on the mixing container 20, and a wire hole 60a is enclosed between the mounting frame 60 and the mixing container 20. Figure 1 as well as Figure 5 That is, a rope can be inserted through the wire hole 60a, and then the rope can be tied to a branch or a trunk to fix the mixing container 20. In this way, the mixing container 20 and the mixed medicine inside will not pull the first infusion pipe 30, ensuring that the first infusion pipe 30 is firmly connected to the infusion bag 10.

[0070] In some embodiments, see Figure 1 The first infusion pipeline 30 is provided with a flow regulator 70, also known as an infusion regulating valve or an infusion titrator. The flow regulator 70 is used to adjust the infusion volume of the first infusion pipeline 30. In this embodiment, the flow regulator 70 is a product currently available on the market, so no further explanation is given here.

[0071] Please continue reading Figure 1 The infusion bag 10 is provided with a hanging ring 80, which can be realized directly by drilling a hole in the infusion bag 10, or connected to the infusion bag 10 by hot melting or the like. In the specific implementation stage, the user can hammer nails into the tree to facilitate hanging the hanging ring 80. Of course, when there are branches on the tree that can be hung, it can also be hung directly on the branches.

[0072] It should be understood that in the present embodiment, for different fruit tree conditions, due to the different required medicines, the number of first joint parts 21 is often greater than the number of infusion bags 10, and similarly, the number of second joint parts 22 is often greater than the number of second infusion tubes 40, and the extra first joint parts 21 and second joint parts 22 can be connected to the end cover 90 to achieve the closure of the mixing chamber 30a, and in the present embodiment, the connection between the end cover 90 and the first joint part 21 and the second joint part 22 can also be a threaded connection to achieve quick installation and disassembly.
