Description

Technical Field

[0001] The utility model relates to the field of gardening equipment, in particular to a flow dividing device for a plant infusion device with three outlet output states. Background Art

[0002] In large-scale seedling transplanting, fruit tree and forest pest control, many places use the method of hanging bottle infusion - commonly known as "dangling injection". The infusion method can not only solve the short-term supply and demand contradiction of water in the early stage after tree transplanting, thereby promoting rapid survival, but also provide infusion treatment for some fruit tree patients, which can not only improve the survival quality of plant transplanting, but also promote the recovery speed of sick trees. The existing infusion device usually includes an infusion tube, an infusion needle connected to the lower end of the infusion tube, and a bottle cap or needle at the top of the infusion tube for connecting to an infusion bottle or an infusion bag. On the basis of the above-mentioned infusion device, if a bottle of liquid medicine wants to be infused into two connected trees at the same time, there are two methods, either to install a three-way component at the lower part of the infusion tube, and then connect two needles to the three-way component, so that the two trees can be infused at the same time; or to use another set of infusion devices to be inserted into the same medicine bottle or infusion bag, so that the two trees can be infused at the same time.

[0003] In addition, when the tree infusion pump is in use, in order to make the liquid flow more smoothly, a certain amount of gas is usually manually injected into the medicine bottle or infusion bag before the infusion. During the infusion process, the medicine is pressed into the tree trunk by the pressure of the gas. In order to cooperate with this process, a switch valve is also provided on the infusion tube of the infusion pump to control the opening and closing of the infusion tube.

[0004] The existing infusion tube is relatively time-consuming and labor-intensive to complete the above steps, and the cost of the infusion set can be further reduced. Utility Model Content

[0005] The utility model aims to overcome the shortcomings of the prior art and provide a flow dividing device for a plant infusion device with three outlet output states.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a shunt device for a plant infusion device, characterized in that it includes an inner shell and an outer shell, the outer shell includes an inner cavity, the inner cavity is an open surface at the top of the outer shell, and the inner cavity is a hollow cylindrical shape, an inlet pipe and two outlet pipes are arranged on the outer wall of the outer shell, and the inlet pipe and the two outlet pipes are both connected to the inner cavity.

[0007] The inner shell is cylindrical, and a liquid channel is arranged inside the inner shell. Two openings are arranged at both ends of the liquid channel on the outer cylindrical surface of the inner shell respectively, one of the two openings is an inlet area, and the other is an outlet area, and the shapes of the inlet area and the outlet area are both long strips.

[0008] A rotating shaft is arranged at the center of the inner shell, the inner shell is buckled in the inner cavity of the outer shell, the outer wall of the inner shell contacts the inner cavity wall of the outer shell, and the outer shell and the inner shell are fixedly connected in the axial direction through the rotating shaft.

[0009] As the inner shell and the outer shell rotate, when the inlet pipe is connected to the inlet area, the two outlet pipes are all connected to the outlet area, and at this time, both outlet pipes output liquid; as the inner shell and the outer shell continue to rotate, when the inlet pipe is connected to the inlet area, one of the two outlet pipes is connected to the outlet area, and at this time, one outlet pipe outputs liquid; as the inner shell and the outer shell continue to rotate, when the inlet pipe is not connected to the inlet area, and the two outlet pipes are not connected to the outlet area, the device does not output liquid.

[0010] For further optimization, a sealing sleeve is further arranged between the inner shell and the outer shell, the outer wall of the sealing sleeve is in contact with the inner wall of the outer shell, and a hole is opened at a position overlapping with the inlet pipe and the outlet pipe.

[0011] In a further optimization, an outlet tube of the housing is configured as an infusion needle extending outward.

[0012] Further optimization is that an ear plate is arranged on the lower bottom surface of the inner shell, so that the user can twist the inner shell through the ear plate to change the output state of the liquid of the device.

[0013] In summary, the utility model mainly has the following beneficial effects:

[0014] Through the mutual twisting and cooperation between the inner shell and the outer shell, the device can achieve the effects of closed water discharge, single outlet pipe water discharge and double outlet pipe simultaneous water discharge, and the device can infuse one tree or two trees at the same time. Finally, when inflating the medicine bottle or the infusion bag, the device is first adjusted to the single outlet pipe water discharge mode, the upper end of the device is connected with the medicine bottle or the infusion bag, and air is pumped into the medicine bottle or the infusion bag through the infusion pipe at the outlet pipe of the device, and then the device is adjusted to closed water discharge, so that the gas pressure can be locked in the medicine bottle or the infusion bag. After the infusion needle at the outlet pipe of the device is connected to the plant, the single outlet pipe water discharge mode and the double outlet pipe simultaneous water discharge mode can be selected for injection.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0024] like Figures 1 to 9 As shown, in this example, a shunt device for a plant infusion device includes a cylindrical inner shell 1 and a cylindrical outer shell 2, wherein the outer shell 2 includes an inner cavity 2-1, and the inner cavity 2-1 is set as an open surface at the top of the outer shell 2, and the shape of the inner cavity 2-1 is a hollow cylinder, and an inlet pipe 3 and two outlet pipes 4 are arranged on the outer wall of the outer shell 2, and the inlet pipe 3 and the two outlet pipes 4 are connected to the inner cavity 2-1.

[0025] The inner shell 1 is also cylindrical in shape, and a liquid channel 1-1 is provided inside the inner shell 1. In this embodiment, the liquid channel 1-1 is a hollow space inside the inner shell 1. In other embodiments, the liquid channel 1-1 can also be provided as a tubular channel. Two openings 1-2 are provided at both ends of the liquid channel 1-1 on the outer cylindrical surface of the inner shell 1. One of the two openings 1-2 is provided as an inlet area, and the other opening 1-2 is provided as an outlet area. In this embodiment, the inlet area and the outlet area are both in the shape of long strips, and the inlet area and the outlet area are separated by a cylindrical surface and are opposite to each other.

[0026] A rotating shaft 5 is provided at the center of the inner shell 1. The inner shell 1 is buckled into the inner cavity 2-1 of the outer shell 2. The outer wall of the inner shell 1 contacts the inner cavity wall of the outer shell 2. The outer shell 2 and the inner shell 1 are fixedly connected in the axial direction by the rotating shaft 5, and it is ensured that no liquid leakage occurs between the outer wall of the inner shell 1 and the inner cavity wall of the outer shell 2. The two can also rotate around the rotating shaft 5.

[0027] As the inner shell 1 and the outer shell 2 rotate, when the inlet tube 3 is connected to the inlet area, and the two outlet tubes 4 are all connected to the outlet area, the inlet tube 3 and the two outlet tubes 4 are connected in a liquid path, so the two outlet tubes 4 output liquid. At this time, when the plant infusion device equipped with the device is used, two trees can be infused at the same time. As the inner shell 1 and the outer shell 2 continue to rotate, when the inlet tube 3 is connected to the inlet area, one of the two outlet tubes 4 is connected to a part of the outlet area, and the other outlet tube 4 is blocked by the side wall of the inner shell 1, one outlet tube 4 outputs liquid. At this time, the plant infusion device of the device can only be infused to one tree; this state can also be used to fill the medicine bottle or infusion bag with gas pressure to provide pressure for the subsequent infusion. As the inner shell 1 and the outer shell 2 continue to rotate, when the inlet tube 3 is not connected to the inlet area, and the two outlet tubes 4 are not connected to the outlet area, that is, the inlet tube 3 and the outlet tube 4 are both opposite to the outer wall of the inner shell 1, the device does not output liquid at this time. After gas is injected into the medicine bottle or infusion bag, the device is adjusted to this state to seal the gas pressure in the medicine bottle or infusion bag to prepare for subsequent infusion operations.

[0028] like Figures 5 to 8 As shown, further optimization is performed, a sealing sleeve 6 is further provided between the inner shell 1 and the outer shell 2, the outer wall of the sealing sleeve 6 is in contact with the inner wall of the outer shell 2, and holes 6-1 are provided at the locations of the sealing sleeve 6 that overlap with the inlet pipe 3 and the outlet pipe 4. By adding the sealing sleeve 6 between the inner shell 1 and the outer shell 2, the sealing between the outer wall of the inner shell 1 and the inner cavity wall of the outer shell 2 is further ensured to prevent the drug solution from leaking therefrom.

[0029] like Fig. 9 As shown, in further optimization, one outlet tube 4 of the housing 2 directly extends outward, and finally extends to form an infusion needle 7 extending outward. When in use, the infusion needle 7 is directly inserted into the infusion hole on a tree, and another outlet tube 4 is installed with another independent infusion needle through an infusion hose, and the infusion needle is used to infuse the second tree. With such a structure, the manufacturing cost of a section of infusion hose is directly saved.

[0030] like Figure 2 , Figure 6 and Figure 7 As shown, it is further optimized that an ear plate 8 is provided on the lower bottom surface of the inner shell 1, so that the user can twist the inner shell 1 through the ear plate 8, thereby more easily changing the connectivity state of the liquid passage in the device, thereby changing the output state of the liquid in the device.

[0031] This device is a component of an infusion set. The inlet tube 3 on the shell 2 is connected to a medicine bottle or an infusion bag through an infusion hose, and the outlet tube 4 on the shell 2 is connected to a tree through another infusion tube and an infusion needle. Compared with the existing infusion sets, the infusion set using this device has a higher degree of integration, lower cost, and is more convenient to use.

[0032] Although an embodiment of the utility model has been shown and described, this specific embodiment is merely an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
