Description

Technical Field

[0001] This utility model relates to the field of liquid diversion technology, and in particular to a liquid diversion device and a collection bag having the device. Background Technology

[0002] In agricultural and industrial production, liquids are often produced. Some liquids are produced quickly and in large quantities, and can be quickly collected into tanks, while others are produced slowly and in small quantities, requiring a long time to collect, such as birch sap. For liquids that require long-term collection, liquid collection devices are often used. The liquid collection device is hung on the part of the birch tree that needs to be collected, and the liquid is collected slowly. Once the collection bag is full of liquid, it is removed and stored.

[0003] In existing technologies, when extracting sap from trees, a drill is used to make a hole in the trunk, and then a food-grade plastic tube is used to extract the sap. This method often involves making a hole in the top of the sap bag and then using a fixing nail to fix the sap bag to the trunk. As the extraction time increases, the weight of the sap bag also increases, causing the hole in the sap bag to expand upwards due to the increased weight of the liquid, eventually causing it to detach from the fixing nail and fall off.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0026] like Figure 1 As shown, a liquid guiding device includes: a T-shaped guiding pipe 2 and a suspension component 3 for suspending a liquid collection container; the T-shaped guiding pipe 2 includes a horizontal guiding pipe 201 for extracting liquid after insertion into a tree trunk and a vertical guiding pipe 202 for connecting the liquid collection container; one end of the horizontal guiding pipe 201 is a liquid inlet and the other end is a closed end; the bottom end of the vertical guiding pipe 202 is a liquid outlet; the top ends of the horizontal guiding pipe 201 and the vertical guiding pipe 202 are fixedly connected, and the vertical guiding pipe 202 is close to the closed end of the horizontal guiding pipe 201; both the horizontal guiding pipe 201 and the vertical guiding pipe 202 have channels for liquid flow and are connected to each other; the suspension component 3 is detachably connected to the horizontal guiding pipe 201.

[0027] In this embodiment, the longitudinal guide tube 202 is a hollow structure with open ends. The open end of the transverse guide tube 201 has a channel communicating with the interior of the longitudinal guide tube 202. That is, the open end of the transverse guide tube 201 opens towards the closed end to form a channel for liquid flow, but does not communicate with the closed end. It extends downwards from the connection point with the top of the longitudinal guide tube 202, thus connecting with the hollow structure of the longitudinal guide tube 202 to form a channel for liquid flow. The open end of the transverse guide tube 201 is a liquid inlet, and liquid is extracted after being inserted into the tree trunk for fixation. The guide tube 202 is located at the lower end of the transverse guide tube 201. The transverse guide tube 201 can not only be used to guide liquid, but also has its open end inserted into the tree trunk and fixed to form a stable support point. The transverse guide tube is used to suspend the liquid collection container through the connection between it and the suspension component 3. Compared with the existing suspension method, the transverse guide tube 201 itself has an additional fixed point, while the suspension component 3 adds a suspension method and increases the contact area with the liquid collection container. Even if used for a long time, the liquid collection container will not fall down, thus improving stability.

[0028] like Figure 1-2 As shown, both the transverse guide tube 201 and the longitudinal guide tube 202 are cylindrical; the inlet end of the transverse guide tube 201 has a notch.

[0029] In this embodiment, after the liquid inlet end of the transverse guide tube 201 is notched, a sharp part is formed, which can better guide the liquid and facilitate the insertion and fixing of the liquid inlet end of the transverse guide tube 201, that is, the notched end, into the trunk.

[0030] like Figure 1-2 As shown, the suspension component 3 includes a ring 301, a connecting rod 302, and a load-bearing rod 303; the load-bearing rod 303 is arranged horizontally and its top surface is fixedly connected to one end of the connecting rod 302 at the middle position; the other end of the connecting rod 302 is fixedly connected to the ring 301; an arc-shaped groove 2011 is provided between the closed end of the horizontal guide pipe 201 and the vertical guide pipe 202; the arc-shaped groove 2011 is located at the top end of the horizontal guide pipe 201; the ring 301 is disposed in the arc-shaped groove 2011.

[0031] In this embodiment, the load-bearing rod 303 is detachably connected to the liquid collection container; it is inserted into the ring 301 through a circular hole from one end of the transverse guide tube 201 near the longitudinal guide tube 202, and is fitted on the outside of the transverse guide tube 201, and then placed in the arc-shaped groove 2011; in use, as the liquid collection container increases over time, the liquid inside increases, and the weight also increases, that is, it gives the load-bearing rod 303 a downward force. The load-bearing rod 303 also gives the ring 301 a downward force. The end of the transverse guide tube 201 away from the longitudinal guide tube 202 is inserted into the trunk and fixed, forming a stable support point, which increases the stability of suspending the liquid collection container.

[0032] like Figure 1-2 As shown, the transverse guide tube 201 is fixedly connected to a sealing plug 9.

[0033] In this embodiment, the T-shaped guide tube 2, the suspension component 3, and the sealing plug 9 are all made of the same plastic material; the sealing plug 9 is fixedly connected to one side of the transverse guide tube 201. Since both the transverse guide tube 201 and the sealing plug 9 are made of plastic, they are fixedly connected by a small amount of the same plastic material, and the sealing plug 9 can be easily removed by forceful rotation; the location of the sealing plug 9 is as follows: Figure 2 As shown, it is set on the side of the transverse guide tube 201; after one liquid extraction cycle, since there is still liquid flowing out, the sealing plug 9 is removed from the transverse guide tube 201. The sealing plug 9 is used to seal the liquid outlet at the bottom of 202 to avoid waste and protect the environment. Example

[0034] like Figure 1 and 3 As shown, a collection bag with a liquid guiding device includes: a liquid guiding device and a bag body 1; the bag body 1 is rectangular; heat-sealing lines 4 are fixedly connected near the four edges of the bag body 1, forming a space for containing liquid; the heat-sealing line 4 at the top of the bag body 1 has a liquid inlet 401; the bag body 1 is fixedly connected to two heat-sealing lines 5, and two right angles at the upper end of the bag body 1 respectively form a suspension area 101; multiple through holes 102 for suspending the bag body 1 are opened in the suspension area 101; the bottom end of the longitudinal guiding tube 202 of the liquid guiding device is inserted into the bag body 1 through the liquid inlet 401; the load-bearing rod 303 of the liquid guiding device is detachably connected to the bag body 1.

[0035] In this embodiment, the inner wall of the bag body 1 is coated with graphene nanomaterials; the bag body 1 is composed of two identical rectangular plastic sheets, each with a corresponding through hole 102; the rectangular plastic sheets are transparent; a closed heat-sealing line 4 is formed near the edge of the bag body 1 by a heat-sealing process, which seals and fixes the edge of the bag body 1, creating a sealed space inside the bag body 1 to contain liquid; one end of a second heat-sealing line 5 is connected to a longitudinal heat-sealing line 4 near the top of the bag body 1, and the other end is connected to a heat-sealing line 4 near one end at the top of the bag body 1; one end of another second heat-sealing line 5 is connected to another longitudinal heat-sealing line 4 near the top of the bag body 1, and the other end is connected to a heat-sealing line 4 near the other end at the top of the bag body 1; the hanging area 101 is isolated from the space containing liquid and is triangular; the liquid inlet 401 is located in the middle of the heat-sealing line 4 at the top of the bag body 1.

[0036] like Figure 1 , Figure 3 as well as Figure 4As shown, the bag body 1 is fixedly connected with two heat-sealing lines 36; one end of each of the two heat-sealing lines 36 is connected to a heat-sealing line 25, and the other end of each of the two heat-sealing lines 36 is connected to a heat-sealing line 14 at the top of the bag body 1; the other ends of the two heat-sealing lines 36 are located on both sides of the liquid inlet 401 and form two hanging areas 2103; the rectangular plastic sheet of the two hanging areas 2103 of the two bag bodies 1 away from the tree trunk is provided with through holes 2104; the two through holes 2104 are symmetrically arranged; the two ends of the load-bearing rod 303 are inserted into the hanging area 2103 through the through holes 2104.

[0037] In this embodiment, both ends of the load-bearing rod 303 are inserted into the second suspension area 103, increasing the contact area for suspension. During use, as the liquid inside the bag 1 gradually increases, the top of the second suspension area 103 exerts a downward force on the load-bearing rod 303. The top of the second suspension area 103 and the through hole 102 are simultaneously suspended on the load-bearing rod 303 and the hook, bearing more weight. When the liquid gradually increases to a certain amount, the bag will not fall. If the through hole 102 and the hook are used alone to suspend the bag 1, when the liquid inside the bag 1 increases to a certain weight, the through hole 102 will deform or form an opening with the upper end of the bag 1 because the bag 1 is made of plastic, causing the bag 1 to fall.

[0038] like Figure 3 and 5 As shown, a flow guide nozzle 7 is fixedly connected inside the bag body 1; the flow guide nozzle 7 includes two plastic films; the plastic films include a rectangular film 701, an isosceles trapezoidal film 702, and a rectangular film 703; the lower end of the rectangular film 701 is fixedly connected to the long bottom end of the isosceles trapezoidal film 702, and the short bottom end of the isosceles trapezoidal film 702 is fixedly connected to the rectangular film 703; the rectangular film 701, the isosceles trapezoidal film 702, and the rectangular film 703 are integrally formed; the isosceles trapezoidal film 702 is set at the liquid inlet 401 and matches the liquid inlet 401, the rectangular film 701 is located outside the bag body 1, and the rectangular film 703 is located inside the bag body 1; the bottom end of the longitudinal flow guide tube 202 is inserted into the rectangular film 703.

[0039] In this embodiment, rectangular membrane 703 is located between two suspension areas 103; two plastic films are overlapped, one plastic film is tightly attached to the rectangular plastic sheet of the bag body 1 away from the tree trunk, and the other plastic film is tightly attached to the rectangular plastic sheet of the bag body 1 near the tree trunk; the isosceles trapezoidal membrane 702 facilitates the insertion of the longitudinal guide tube 202; in use, when the longitudinal guide tube 202 is inserted between the two rectangular membranes 703, the two rectangular membranes 703 are supported and their inner surfaces are attached to the outer surface of the longitudinal guide tube 202; the guide nozzle 7 is provided to better seal the liquid during collection; the plastic film can be PE film and is colored, which has a certain electrostatic adsorption effect and can be more tightly attached to the outer surface of the longitudinal guide tube 202.

[0040] like Figure 3 and 5 As shown, the edges of the two waists of the isosceles trapezoidal membrane 702, the two sides of the rectangular membrane 703, and the bag body 1 are fixedly connected by heat-sealing line 8; the length of the rectangular membrane 703 is longer than the longitudinal guide tube 202.

[0041] In this embodiment, a liquid channel formed by a transparent plastic sheet (hereinafter referred to as the channel) can also be provided inside the bag body 1. The channel is open at both ends. This channel is fitted over the outside of the rectangular membrane 703 through one end opening and is longer than the rectangular membrane 703. That is to say, liquid flows into this channel through a part of the rectangular membrane 703 and then into the bag body 1. The purpose of setting this channel is that when the bag body 1 is removed, because the channel is long, it will stick together when there is no longitudinal guide tube 202 for internal support, thus achieving a certain sealing effect.

[0042] like Figure 3-4 As shown, the top ends of the two longitudinal heat-sealing lines 4 of the bag body 1 are located at the upper end of the heat-sealing line 4 at the top of the bag body 1; the bottom ends of the two longitudinal heat-sealing lines 4 of the bag body 1 are located at the lower end of the heat-sealing line 4 at the bottom of the bag body 1; the length of the heat-sealing lines 4 at the top and bottom of the bag body 1 is longer than the distance between the two longitudinal heat-sealing lines 4 of the bag body 1.

[0043] In this embodiment, the adjacent heat-sealing lines 4 of the bag body 1 are arranged to cross each other, so that the bag body 1 can bear more weight and prevent the connection of the four heat-sealing lines 4 from tearing and leaking liquid. When in use, after a liquid collection cycle, the load-bearing rod 303 is moved laterally through the through hole 104. After the load-bearing rod 303 is removed, the suspension component 3 is moved upward as a whole and removed from the arc groove 2011. Then the bag body 1 is removed. In order to avoid removing the T-shaped guide tube 2 for continued use next time, since liquid is still flowing out, the sealing plug 9 is removed from the transverse guide tube 201. The sealing plug 9 is used to seal the liquid outlet at the bottom of 202 to prevent liquid from flowing out without the bag body 1, avoid waste, and protect the environment.

[0044] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0045] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
