[0013] The bottom support plate has a through hole running vertically through the inside and outside of the storage tank, and the through hole is connected to the outlet of the storage tank.

[0014] A movable cover plate located inside the storage tank is used to seal the through hole. The storage tank is equipped with a lifting structure that allows the movable cover plate to be lifted and lowered in the vertical direction.

[0015] In a further embodiment of this application, a distribution plate is provided inside the through hole, and a step is provided inside the through hole, with the outer periphery of the lower surface of the distribution plate resting on the step surface.

[0016] The movable cover plate is located within the through-hole section above the step. The lower surface of the movable cover plate presses against the outer periphery of the upper surface of the distribution plate.

[0018] In a further embodiment of this application, the lifting mechanism includes a lifting rod, a lifting block, and

[0019] The lower end of the lifting rod extends into the storage tank and is fixedly connected to the movable cover. The upper end of the lifting rod passes through the tank cover and is positioned above the tank cover. A lifting block is fixedly installed on one end of the lifting rod above the tank cover, and a handle is fixedly installed on the lifting block.

[0020] The can lid is equipped with a lever that presses against the upper surface of the lifting block or rotates to one side of the lifting block.

[0021] The vertical distance between the upper surface of the lever and the upper surface of the can lid is greater than the vertical distance between the lower surface of the movable cover and the upper surface of the bottom support plate.

[0028] 1. In this solution, the centrifugal rotor enables rapid and uniform mixing of birch sap and stabilizer in the storage tank, improving mixing capacity and enhancing the stability of birch sap. The concentration tank and storage tank can operate simultaneously. For example, while concentration is being carried out in the concentration tank, centrifugal mixing can be performed in the storage tank. After the sap in the concentration tank is discharged, the sap mixture in the storage tank can be directly sent to the concentration tank for further concentration, obtaining stable birch sap at a concentration suitable for skincare product preparation. This reduces the waiting time for materials in the concentration tank and improves the working efficiency of the device.

[0038] 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.

[0039] Please see Figure 1-6 A device for extracting and producing birch sap for skincare products includes a storage tank 1, a centrifugal rotating mechanism, and a concentration tank 2. The entire device is about 1.4 meters high and is a small-scale production device. The upper and lower surfaces of the storage tank 1 and the concentration tank are both flat. The storage tank 1 is used to store the sap and stabilizer. The stabilizer is an edible liquid stabilizer. The existing centrifugal rotating mechanism centrifugally stirs the mixed liquid in the storage tank 1 to accelerate the mixing of the liquids. The concentration tank 2 is used to heat and concentrate the mixed liquid discharged from the storage tank 1 to obtain a concentrated liquid as a raw material for skincare products.

[0040] The upper end of the storage tank 1 is open, and the lower end is provided with a discharge port 3 for the juice in the storage tank 1 to be discharged from the tank body; the open end of the storage tank 1 is provided with a tank cover 4 for sealing the open end, and a feeding port 5 is provided on the tank cover 4 for adding juice into the storage tank 1. The juice is filtered before being added to the storage tank 1 to remove impurities.

[0041] The centrifugal rotation mechanism includes a motor 6 and a centrifugal rotor 7. The motor 6 is installed above the tank cover 4, and the centrifugal rotor 7 is located inside the storage tank 1. The motor 6 and the centrifugal rotor 7 form a transmission connection. The centrifugal rotor 7 rotates inside the tank driven by the motor 6, causing centrifugal stirring and mixing inside the tank. The concentration tank 2 is located below the storage tank 1. The top of the concentration tank 2 is provided with an inlet 8, and the outlet 3 is connected to the inlet 8. The mixed liquid in the storage tank 1 flows towards the inlet 8 through the outlet 3 under its own weight and enters the concentration tank 2. The concentration tank 2 is provided with a heating device. The heating device can adopt an existing heating mechanism, such as the existing electric heating method. The specific structure and concentration principle of the concentration tank 2 will not be described in detail here.

[0042] A discharge pipe 9 is fixedly installed on the lower outer side of the concentration tank 2, which communicates with the inside of the concentration tank 2, so as to discharge the concentrated liquid in the concentration tank 2. A discharge valve is installed on the discharge pipe 9 for control.

[0043] A bottom support plate 10 is fixedly installed in the center of the bottom wall inside the storage tank 1. The outer peripheral surface of the bottom support plate 10 is in contact with the inner peripheral wall of the storage tank 1, and the lower surface of the bottom support plate 10 is in contact with the inner bottom surface of the storage tank 1. The bottom support plate 10 and the bottom of the storage tank 1 form a sealed arrangement. The bottom support plate 10 can be fixed to the bottom of the tank by welding.

[0044] The bottom support plate 10 has a through hole 11 that runs vertically through the inside and outside of the storage tank 1. The through hole 11 is connected to the outlet 3 of the storage tank 1. The diameter of the through hole 11 is larger than the diameter of the outlet 3. A movable cover plate 12 is located inside the storage tank 1 to seal the through hole 11. A lifting structure is provided on the storage tank 1 to lift the movable cover plate 12 vertically.

[0045] When using this device, the movable cover plate 12 is positioned inside the through hole 11, sealing the through hole 11. The external juice mixture enters the storage tank 1 through the feeding port 5 on the tank cover 4. When the set amount is reached, feeding is stopped, and the motor 6 is started to drive the centrifugal rotor 7 to centrifuge and stir the juice mixture in the tank, accelerating the mixing of the juice mixture in the tank. When the set mixing time is reached, the motor 6 stops the centrifugal rotor 7, and the movable cover plate 12 is lifted by the lifting structure, causing the movable cover plate 12 to detach from the through hole 11. The juice mixture inside the tank can be discharged from the outlet 3 and flow into the concentration tank 2 through the inlet 8 at the top of the concentration tank 2. It is then heated and concentrated in the concentration tank 2 to obtain a juice concentrate for the preparation of skin care products. During use, the concentration tank 2 and the storage tank 1 can operate simultaneously. For example, when the concentration tank 2 is being concentrated, the storage tank 1 can be centrifugally stirred and mixed. After the juice is discharged from the concentration tank 2, the juice mixture in the storage tank 1 can be directly sent into the concentration tank 2, reducing the waiting time for the concentration tank 2 and improving the working efficiency of the device.

[0046] A distribution plate 13 is provided in the through hole 11, and a step 14 is provided in the through hole 11. The outer periphery of the lower surface of the distribution plate 13 is placed on the step surface. In order to avoid the possibility of the distribution plate 13 moving in the through hole 11, the distribution plate 13 can be assembled in the through hole 11 by interference fit.

[0047] The movable cover plate 12 is located in the through hole 11 section above the step 14. The lower surface of the movable cover plate 12 presses against the outer periphery of the upper surface of the distribution plate 13. The center of the distribution plate 13 has multiple material holes 15 that connect the upper and lower sections of the through hole 11, so that the juice in the storage tank 1 can flow towards the concentration tank 2. Through the material holes 15, there can be multiple flow paths between the storage tank 1 and the concentration tank 2. In providing flow paths, it can also provide further mixing capacity for the juice mixture discharged from the storage tank 1.

[0048] A connecting pipe 16 is welded and fixed inside the through hole 11. The upper end of the connecting pipe 16 is located in the section of the through hole 11 below the step 14. The lower end of the connecting pipe 16 is inserted into the outlet 3 and protrudes from the outer bottom wall of the storage tank 1 to facilitate docking with the inlet 8 at the top of the concentration tank 2. The upper end face of the connecting pipe 16 rests on the outer periphery of the lower surface of the distribution plate 13 to provide a certain support capacity for the distribution plate 13. At the same time, the upper end of the connecting pipe 16 avoids the contact area between the lower surface of the bottom support plate 10 and the inner bottom wall of the storage tank 1, reducing the possibility of leakage from the contact area into the connecting pipe 16.

[0049] To further enhance stability, the outlet 3 of storage tank 1 adopts a constricted shape, wider at the top and narrower at the bottom. The middle section of the connecting pipe 16 also features a corresponding constricted section to fit snugly against it. When the lower end of the connecting pipe 16 is at the inlet 8 at the top of the concentration tank 2, the lowest outer circumferential wall of the constricted section in the middle of the connecting pipe 16 fits snugly against the upper edge of the inlet 8 of the concentration tank 2, thus providing a certain degree of sealing between the outer wall of the connecting pipe 16 and the inlet 8. Alternatively, a sealing ring can be installed between the inlet 8 and the connecting pipe 16 for further sealing.

[0050] The lifting mechanism includes a lifting rod 17 and a lifting block 18. The lower end of the lifting rod 17 extends into the storage tank 1 and is fixedly connected to the movable cover plate 12. The upper end of the lifting rod 17 passes through the tank cover 4 and is positioned above the tank cover 4. A through hole is provided on the tank cover 4 for the lifting rod 17 to pass through. The outer periphery of the lifting rod 17 forms a sliding fit with the inner wall of the through hole. The through hole guides the lifting rod 17 to move up and down. The lifting block 18 is fixedly installed on one end of the lifting rod 17 above the tank cover 4. A handle 19 is fixedly installed on the lifting block 18 for the user to operate the lifting rod 17. A rotatable surface on the tank cover 4 presses against the upper surface of the lifting block 18. Alternatively, the lever 20 can be rotated to one side of the lifting block 18. That is, a rotating shaft 21 is fixedly mounted on the can lid 4, and one end of the lever 20 is sleeved on the upper part of the rotating shaft 21. The lever 20 can rotate around the rotating shaft 21, so that the other end of the lever 20 rotates to the top of the lifting block 18 or to one side of the lifting block 18. When the movable cover plate 12 is in the through hole 11, the lever 20 presses against the upper surface of the lifting block 18, so that the movable cover plate 12 cannot move. When it is necessary for the movable cover plate 12 to be removed from the through hole 11, the lever 20 is pushed away from the upper surface of the lifting block 18, and then the lifting block 18 can be lifted upward by the handle.

[0051] To ensure the sealing of the area below the lifting block 18, a sealing gasket can be added below the lifting block 18, so that the sealing gasket is pressed against the upper surface of the can cover 4 and the lower surface of the lifting block 18.

[0052] The vertical distance between the upper surface of the lever 20 and the upper surface of the tank cover 4 is greater than the vertical distance between the lower surface of the movable cover 12 and the upper surface of the bottom support plate 10. When the movable cover 12 disengages from the through hole 11, the lever 20 can be pushed back to directly below the lower surface of the lifting block 18, thus supporting the lifting block 18. At this time, the movable cover 12 remains disengaged from the through hole 11, ensuring unobstructed passage between the outlet 3 of the storage tank 1 and the inlet 8 of the concentration tank 2. To ensure stable support of the lifting block 18 by the lever 20, two levers 20 can be installed on either side of the lifting block 18, simultaneously pressing down on the upper surface of the lifting block 18 or providing upward support to the lower surface of the lifting block 18.

[0053] An arrow can be engraved on the upper surface of the lifting block 18, and an alignment line can be engraved on the upper surface of the can lid 4 on the side of the lifting block 18. When the arrow points toward the alignment line, it means that after projection from top to bottom, the outer periphery of the movable cover plate 12 coincides with the inner periphery of the through hole 11, which means that the movable cover plate 12 and the through hole 11 are aligned.

[0054] The centrifugal rotor 7 includes a turntable 22, a rotating shaft 23, and eight centrifugal stirring rods 24. The turntable 22 is horizontally positioned in the lower middle part of the storage tank 1. The lower end of the rotating shaft 23 is fixedly located in the middle of the upper surface of the turntable 22, and the upper end of the rotating shaft 23 is connected to the output end of the motor 6. The eight centrifugal stirring rods 24 are evenly spaced and vertically fixed around the outer periphery of the upper surface of the turntable, enclosing the rotating shaft 23 within it. The motor 6 drives the rotating shaft 23 to rotate, thereby causing the turntable 22 to rotate horizontally within the tank, which in turn drives the eight centrifugal stirring rods 24 to rotate, thus stirring and mixing the liquid inside the tank.

[0055] A bottom support shaft 25 is installed inside the storage tank 1. The lower end of the bottom support shaft 25 passes through the middle of the bottom support plate 10 and is located outside the tank body. This end is rotatably mounted on the bottom support plate 10. The upper end of the bottom support shaft is located directly below the turntable 22. A docking block 26 is fixedly installed in the center of the lower surface of the turntable 22. A docking slot with a quadrilateral cross-section is opened on the lower surface of the docking block 26. The upper end of the bottom support shaft 25 is a docking post with a quadrilateral cross-section that is inserted into the docking slot. The bottom support shaft 25, the docking slot, the docking post, and the rotating shaft 23 form a centerline arrangement. The bottom support shaft 25 provides support for the turntable 22, ensuring the stability of the entire centrifugal rotor 7 during rotation.

[0056] An installation space 28 is formed at the bottom of the storage tank 1 for the installation of the bottom support shaft 25. Specifically, an installation groove 29 is formed on the lower surface of the bottom support plate 10, and a sealing element 30 is installed in the installation groove 29. The inner wall of the sealing element 30 forms a seal with the outer wall of the bottom support shaft 25, the upper surface of the sealing element 30 forms a seal with the top wall of the installation groove, and the outer peripheral wall of the sealing element 30 forms a seal with the inner side wall of the installation groove. A pressure block 31 is installed on the bottom support plate 10. The front end of the pressure block 31 contacts the lower surface of the sealing element, forming an installation stop for the sealing element 30. The outer periphery of the pressure block 31 faces the bottom. A connecting mounting ring 32 extends from the lower surface of the bottom support plate 10. The connecting mounting ring 32 is fixedly connected to the lower surface of the bottom support plate 10 by bolts. The pressure block 31 is hollow. A bearing 33 is installed at the lower end of the bottom support shaft 25, and a pressure cover 34 is bolted to the pressure block. The pressure cover 34 forms a seal on the lower end of the bottom support shaft 25. The upper end of the pressure cover 34 has a top stop ring 35 that presses against the lower end of the outer ring of the bearing. The upper end of the outer ring of the bearing is constrained by the pressure block 31. Through this structural design, the bottom support shaft 25 can be installed on the bottom support plate 10 from the outside, which is convenient, quick, and easy to maintain. Since the tank body thickness of the storage tank 1 needs to be increased to meet the design of the through hole 11 on the bottom support plate 10, the bottom support plate 10 is designed in the original tank body. Of course, in specific implementation, the bottom support plate 10 can also be designed to be integrated with the bottom wall of the storage tank 1.

[0057] The top surface of the concentration tank 2 has an insertion groove 27 that corresponds to the lower end of the storage tank 1, into which the lower end of the storage tank 1 is inserted. The inner wall of the insertion groove 27 constrains the outer wall of the storage tank 1. To further enhance the stability of the connection between the concentration tank 2 and the storage tank, a bolt is screwed in from the outer side of the upper end of the concentration tank 2. The bolt passes through the side wall of the insertion groove 27 and pushes into the bottom of the storage tank 1. The design of the insertion groove 27 ensures precise connection between the storage tank 1 and the concentration tank 2, and the bolt enhances the stability of the connection between the storage tank 1 and the concentration tank 2.

[0058] The working principle of this invention is as follows: Birch sap and a stabilizer are fed into storage tank 1. Driven by motor 6, centrifugal rotor 7 is used to centrifuge and stir the birch sap and stabilizer in storage tank 1, ensuring that the stabilizer and birch sap are fully mixed, resulting in a uniform and stable birch sap without stratification or sedimentation. Next, the upward movement of lifting rod 17 causes movable cover plate 12 to move upward within storage tank 1. This upward movement of cover plate 12 opens the channel between storage tank 1 and concentration tank 2, allowing the stable birch sap liquid to enter concentration tank 2 for concentration. The concentration tank 2 extracts the birch sap liquid of the desired cosmetic concentration, which is then discharged through discharge pipe 9.

[0059] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
