Description

Technical Field

[0001] This utility model relates to the field of tree sap collection technology, specifically to birch sap collection syringes and collection bags. Background Technology

[0002] Birch sap is rich in nutrients such as amino acids and vitamins, and is widely used in food, cosmetics, and other fields. Market demand continues to grow, driving the continuous development of birch sap collection technology. However, current birch sap collection methods still have many shortcomings, making it difficult to meet the needs for efficient, hygienic, and convenient collection. Existing collection devices lack reliable fixing and suspension structures. Containers are often placed directly next to tree trunks or on simple supports, making them susceptible to displacement due to external disturbances. In strong winds, the containers may tip over; and the devices are prone to detachment when touched by wild animals. Displacement or tilting of the device can cause the collection needle to detach from the birch tree's collection hole, interrupting the collection process. Repositioning and reinstallation require additional time, significantly reducing daily collection efficiency. This is especially true during the peak birch sap secretion period in spring, where interrupting collection can lead to missing the optimal collection window. In traditional collection devices, the collection container and collection tube are usually fixedly connected. Once the container is full of sap, the entire device must be disassembled to replace the empty container. During disassembly and reinstallation, not only must the collection needle be pulled out, but the position must also be readjusted, making the operation cumbersome and time-consuming. For example, if a single birch tree is collected 3-5 times a day, each container replacement takes 5-8 minutes. In large-scale collection, staff need to manage dozens or even hundreds of birch trees, and a significant amount of time is spent on device disassembly and installation, resulting in a limited collection volume per unit time, which is difficult to meet the needs of large-scale production. Therefore, we propose birch sap collection needles and collection bags to solve the existing problems. Utility Model Content

[0003] The purpose of this invention is to provide a birch sap collection syringe and collection bag to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a birch sap collection needle and collection bag, including a collection needle, which includes an inlet, a hanging ear, a suspension bracket, a lifting strap, a collection bag, an outlet, a connecting groove, and a channel. The upper end of the suspension bracket is provided with an inlet, and an outlet is fixedly connected to the inlet on one side of the suspension bracket. A channel is provided between the outlet and the inlet, and the inlet is detachably connected to the collection bag through the outlet. A steam strip is provided inside the collection bag, and the steam strip cooperates with the outlet.

[0005] Preferably, the suspension bracket has hanging ears fixedly connected to both sides, and the collection bag has symmetrical connecting grooves on the side near the liquid outlet. One side of the hanging ear is located on the connecting groove, and the hanging ear has a cylindrical structure. A limiting component is fixedly connected to one side of the hanging ear.

[0006] Preferably, the collection bag is made of transparent food-grade PA / PE material, and the connection between the liquid outlet and the liquid inlet is provided with reinforcing ribs, which are evenly distributed in a ring on the outside of the channel.

[0007] Compared with the prior art, the beneficial effects of this utility model are: 1. Align the collection bag with the outlet of the collection needle, ensuring the gas strip inside the collection bag completely covers the outer wall of the outlet. The gas strip has elastic sealing properties, forming a tight seal when it fits against the outlet, preventing leakage during subsequent raw liquid delivery. Simultaneously, since the inlet and outlet are fixedly connected and have internal channels, the collection bag has already formed a raw liquid flow path through these channels. After the collection bag and suspension bracket are securely sealed, symmetrically align the connecting groove on the side of the collection bag closest to the outlet with the hanging ears on both sides of the suspension bracket, and insert the hanging ears into the connecting groove. With a cylindrical structure, the insertion process is smooth and can limit the vertical swaying of the collection bag. At the same time, the limiting piece on the side of the hanging ear will lock onto the outside of the connecting groove to prevent the collection bag from falling off the hanging ear due to gravity during subsequent collection, further fixing the position of the collection bag. The entire device is suspended and positioned by the lifting strap adapted to the suspension bracket, suspending the entire device on the birch trunk or a special collection bracket. Adjust the suspension height and angle to ensure that the liquid inlet of the collection needle is vertically or obliquely aligned with the birch tree. The collection hole is usually a small hole drilled manually in the trunk to draw out the original liquid in the tree, avoiding the liquid inlet from being misaligned and causing collection failure.

[0008] 2. Insert the inlet of the collection syringe into the collection hole of the birch tree. Due to the natural pressure of the sap within the birch tree, similar to plant transpiration and the tree's own conduction pressure, the sap will automatically enter the syringe through the inlet. The sap is then transported through the channel to the collection bag. The annular reinforcing ribs at the connection between the outlet and the inlet are evenly distributed on the outside of the channel to enhance the structural strength of this part. This prevents the channel from deforming or the connection from breaking due to the increased weight after the collection bag is filled with sap, ensuring that the sap delivery path remains unobstructed. Since the collection bag is made of transparent food-grade PA / PE material, staff can visually observe the volume of sap inside the bag without disassembling the device, making it easy to determine whether the collection bag needs to be replaced.

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0012] like Figures 1-4 As shown, the birch sap collection needle and collection bag proposed in this utility model include a collection needle, which includes an inlet 1, a hanging ear 2, a suspension bracket 3, a lifting strap 4, a collection bag 5, an outlet 7, a connecting groove 8, and a channel 9. The inlet 1 is provided at one end of the suspension bracket 3, and the outlet 7 is fixedly connected to the inlet 1 on one side of the suspension bracket 3. A channel 9 is provided between the outlet 7 and the inlet 1, and the collection bag 5 is detachably connected to the inlet 1 through the outlet 7. A steam strip 6 is provided inside the collection bag 5, and the steam strip 6 cooperates with the outlet 7.

[0013] In an optional embodiment, the suspension bracket 3 is fixedly connected to the two sides of the hanging ear 2, and the collection bag 5 is symmetrically provided with the connecting groove 8 on the side near the liquid outlet 7. One side of the hanging ear 2 is located on the connecting groove 8, and the hanging ear 2 has a cylindrical structure. One side of the hanging ear 2 is fixedly connected to the limiting member 10. Align the collection bag 5 with the outlet 7 of the collection needle, ensuring that the gas strip 6 inside the collection bag completely covers the outer wall of the outlet 7. The gas strip 6 has elastic sealing properties, forming a tight seal when it fits against the outlet 7, preventing leakage during subsequent raw liquid delivery. Simultaneously, since the inlet 1 and outlet 7 are fixedly connected and have an internal channel 9, the collection bag 5 now forms a raw liquid flow path through the channel 9 between the outlet 7 and inlet 1. After the collection bag 5 and suspension bracket 3 are fixedly and sealed, symmetrically align the connecting groove 8 on the side of the collection bag 5 closest to the outlet 7 with the hanging ears 2 on both sides of the suspension bracket 3, and insert the hanging ears 2 into the connecting groove 8. Because the hanging ear 2 has a cylindrical structure, the insertion process is smooth and can limit the vertical swaying of the collection bag 5. At the same time, the limiting part 10 on one side of the hanging ear 2 will be locked on the outside of the connecting groove 8 to prevent the collection bag 5 from falling off the hanging ear 2 due to gravity during subsequent collection, and further fix the position of the collection bag. The overall suspension and positioning of the device is achieved by using the lifting strap 4 adapted to the suspension bracket 3 to suspend the entire device on the birch trunk or a special collection bracket. Adjust the suspension height and angle to ensure that the liquid inlet 1 of the collection needle can be vertically or obliquely aligned with the collection hole of the birch tree. The collection hole is usually a small hole drilled manually on the trunk to draw out the original liquid in the tree. Avoid the liquid inlet being offset, which may cause collection failure.

[0014] In an optional embodiment, the collection bag 5 is made of transparent food-grade PA / PE material, and the connection between the liquid outlet 7 and the liquid inlet 1 is provided with reinforcing ribs, which are evenly distributed in a ring on the outside of the channel 9. Insert the inlet 1 of the collection syringe into the collection hole of the birch tree. Due to the natural pressure of the original liquid inside the birch tree, similar to the transpiration of plants and the transport pressure of the tree itself, the original liquid will automatically enter the syringe through the inlet 1. The original liquid is then transported through the channel to the collection bag. The annular reinforcing ribs at the connection between the outlet 7 and the inlet 1 are evenly distributed on the outside of the channel to enhance the structural strength of this part. This prevents the channel 9 from deforming or the connection from breaking due to the increased weight after the collection bag is filled with original liquid. This ensures that the original liquid transport path is always unobstructed. Since the collection bag is made of transparent food-grade PA / PE material, the staff can directly observe the volume of original liquid in the bag without disassembling the device, making it easy to determine whether the collection bag needs to be replaced.

[0015] The working principle of this utility model is as follows: When using the device, align the collection bag 5 with the liquid outlet 7 of the collection needle, so that the gas strip 6 inside the collection bag completely wraps around the outer wall of the liquid outlet 7. The gas strip 6 has elastic sealing properties and can form a tight sealing structure after fitting with the liquid outlet 7, preventing leakage during subsequent raw liquid transportation. At the same time, since the liquid inlet 1 and the liquid outlet 7 are fixedly connected and have an internal channel 9, the collection bag 5 has formed a raw liquid flow path through the channel 9 between the liquid outlet 7 and the liquid inlet 1. After the collection bag 5 and the suspension bracket 3 are fixedly and sealed, symmetrically open the connecting groove 8 on the side of the collection bag 5 near the liquid outlet 7 and align it with the hanging ears 2 on both sides of the suspension bracket 3, and then hang the bag 5... Ear 2 is embedded in connecting groove 8. Since ear 2 is cylindrical, the embedding process is smooth and can limit the vertical swaying of collection bag 5. At the same time, the limiting piece 10 on one side of ear 2 will be stuck on the outside of connecting groove 8 to prevent collection bag 5 from falling off ear 2 due to gravity during subsequent collection. This further fixes the position of collection bag. The entire device is suspended and positioned by the lifting strap 4 adapted to the suspension bracket 3. The entire device is suspended on the birch trunk or a special collection bracket. The suspension height and angle are adjusted to ensure that the liquid inlet 1 of the collection needle can be vertically or obliquely aligned with the collection hole of the birch tree. The collection hole is usually a small hole drilled manually on the trunk to draw out the original liquid in the tree. This avoids the liquid inlet from being offset, which would cause collection failure. Insert the inlet 1 of the collection syringe into the collection hole of the birch tree. Due to the natural pressure of the original liquid inside the birch tree, similar to the transpiration of plants and the transport pressure of the tree itself, the original liquid will automatically enter the syringe through the inlet 1. The original liquid is then transported through the channel to the collection bag. The annular reinforcing ribs at the connection between the outlet 7 and the inlet 1 are evenly distributed on the outside of the channel to enhance the structural strength of this part. This prevents the channel 9 from deforming or the connection from breaking due to the increased weight after the collection bag is filled with original liquid. This ensures that the original liquid transport path is always unobstructed. Since the collection bag is made of transparent food-grade PA / PE material, the staff can directly observe the volume of original liquid in the bag without disassembling the device, making it easy to determine whether the collection bag needs to be replaced.
