In order to facilitate the placement, the staff usually keep the door open until all the medicines are placed in the freeze dryer. During the interval of feeding the medicines, the cold air in the freeze dryer will continue to escape to the outside, causing the overall temperature of the equipment to drop, resulting in energy loss. In addition, a motor is installed in the above freeze dryer, which further increases the loss of electricity, and the overall effect is not energy-saving. Utility Model Content
[0005] In view of the problem in the prior art that: during the interval of feeding medicines, the cold air in the freeze dryer will continue to escape outward, causing the overall temperature of the equipment to become low, resulting in energy loss, and the above-mentioned freeze dryer is also equipped with a motor, which further increases the loss of electric energy and is not energy-saving as a whole, the main purpose of the utility model is to provide an energy-saving capping freeze dryer.

[0007] By adopting the above technical solution, the wrist is used to resist the side of the shaft disk, so that the rotating shaft and the shaft disk can be rotated. At this time, the torsion spring is squeezed and tightened. When the staff takes the next part of the medicine, the torsion spring is not subjected to force and will automatically reset, thereby driving the rotating shaft and the shaft disk to reset, so that the outer side of the shaft disk contacts the inner wall of the circular groove, thereby reducing the cold air escape during the interval of taking the medicine, thereby making the temperature inside the capping freeze dryer constant and reducing energy loss.
[0008] As a preferred embodiment, both sides of the capping freeze dryer body are fixedly connected with a protection box, the bottom end of the inner wall of the protection box is fixedly connected with a connecting pipe, and the end of the connecting pipe away from the protection box extends to the interior of the capping freeze dryer body.

[0012] As a preferred implementation, a one-way valve is fixedly installed inside the connecting pipe.
[0013] By adopting the above technical solution, the cold air in the freeze-drying chamber is prevented from flowing back into the protective box.
[0014] As a preferred embodiment, the interior of the protection box is rotatably connected to a closed door via a hinge, and a handle is fixedly connected to the outer side of the closed door.
[0015] By adopting the above technical solution and setting a closed door, the escape of cold air in the freeze-drying room can be reduced.
[0016] As a preferred embodiment, a visual window is fixedly installed inside the capping freeze dryer body.
[0017] By adopting the above technical solution, the staff can observe the situation in the freeze-drying room.
[0018] Compared with the prior art, the advantages and positive effects of the utility model are:
[0019] In the utility model, when it is necessary to put medicines into the freeze-drying chamber in the main body of the capping freeze dryer, the medicines can be held by hand and the side of the shaft disk can be resisted by the wrist, so that the rotating shaft and the shaft disk can be rotated, so that the staff can put the medicines into the freeze-drying chamber. At this time, the torsion spring is squeezed and tightened. When the staff takes the next part of the medicine, the torsion spring is not subjected to force and will automatically reset, thereby driving the rotating shaft and the shaft disk to reset, so that the outer side of the shaft disk contacts the inner wall of the circular groove, reducing the cold air escape phenomenon in the interval of taking the medicine, thereby making the temperature in the main body of the capping freeze dryer constant, reducing energy loss, and thus achieving energy-saving effect.

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.
[0026] Reference Figure 1-4 A energy-saving gland freeze dryer comprises a gland freeze dryer body 1, a freeze drying chamber 6 is provided inside the gland freeze dryer body 1, circular grooves 13 are provided at both ends inside the gland freeze dryer body 1, mounting grooves 16 are provided inside the gland freeze dryer body 1 and on both sides of the circular groove 13, a rotating shaft 8 is rotatably connected between the two mounting grooves 16, a shaft disc 5 is fixedly connected to the outer side of the rotating shaft 8, the outer side of the shaft disc 5 is fitted with the circular groove 13, a second fixed block 10 is fixedly connected to the bottom end of the inner wall of the mounting groove 16, a first fixed block 9 is fixedly connected to the inner wall of the mounting groove 16, and torsion springs 11 are sleeved on both ends of the outer side of the rotating shaft 8, one end of the torsion spring 11 is overlapped on the outer side of the first fixed block 9, and the other end of the torsion spring 11 is overlapped on the outer side of the second fixed block 10.
[0027] When it is necessary to put the medicine into the freeze-drying chamber 6 in the capping freeze dryer body 1, the medicine can be held by hand and the side of the shaft disk 5 can be resisted by the wrist, so that the rotating shaft 8 and the shaft disk 5 can be rotated, so that the staff can put the medicine into the freeze-drying chamber 6. At this time, the torsion spring 11 is squeezed and tightened. When the staff takes the next part of the medicine, the torsion spring 11 is not subjected to force and will automatically reset, thereby driving the rotating shaft 8 and the shaft disk 5 to reset, so that the outer side of the shaft disk 5 contacts the inner wall of the circular groove 13, reducing the cold air escape phenomenon in the interval of taking the medicine, thereby making the temperature in the capping freeze dryer body 1 constant, reducing energy loss, and thus achieving energy-saving effect. No additional electrical equipment is set in the capping freeze dryer body 1, which reduces the consumption of electricity and further improves the energy-saving effect of the device.
[0028] Reference Figure 2 Both sides of the capping freeze dryer body 1 are fixedly connected with a protection box 2, the bottom end of the inner wall of the protection box 2 is fixedly connected with a connecting pipe 7, and one end of the connecting pipe 7 away from the protection box 2 extends to the interior of the capping freeze dryer body 1.
[0029] When the medicines are placed in the freeze-drying chamber 6, cold air will escape and part of it will be stored in the protective box 2. By setting the connecting pipe 7, the cold air can return to the freeze-drying chamber 6, further reducing the escape of cold air and ensuring the constant temperature in the freeze-drying chamber 6.
[0030] Reference Figure 4A sealing gasket 14 is fixedly connected to the inner wall of the circular groove 13, and a sealing layer 12 is fixedly connected to the outer side of the shaft disc 5. The sealing layer 12 is in contact with the sealing gasket 14. The sealing gasket 14 and the sealing layer 12 are used in conjunction with each other to improve the sealing performance between the circular groove 13 and the shaft disc 5.
[0031] Reference Figure 3 A one-way valve 15 is fixedly installed inside the connecting pipe 7 to prevent the cold air in the freeze-drying chamber 6 from flowing back into the protection box 2.
[0032] Reference Figure 2 The interior of the protective box 2 is rotatably connected to a closed door 4 via a hinge, and a handle is fixedly connected to the outer side of the closed door 4. By setting the closed door 4, the escape of cold air in the freeze-drying chamber 6 is reduced.
[0033] Reference Figure 1 A visual window 3 is fixedly installed inside the capping freeze dryer body 1 so that the staff can observe the situation inside the freeze drying chamber 6.
[0034] Working principle: When it is necessary to put the medicine into the freeze-drying chamber 6 in the main body 1 of the freeze-drying machine with a cap, the medicine can be held by hand and the side of the shaft disc 5 can be touched by the wrist, so that the rotating shaft 8 and the shaft disc 5 can be rotated, so that the staff can put the medicine into the freeze-drying chamber 6. At this time, the torsion spring 11 is squeezed and tightened. When the staff takes the next part of the medicine, the torsion spring 11 is not stressed and will automatically reset, which will drive the rotating shaft 8 and the shaft disc 5 to reset, so that the outer side of the shaft disc 5 contacts the inner wall of the circular groove 13, reducing the friction when taking the medicine. Cold air escapes in the intervals between the medicines, which makes the temperature inside the capping freeze dryer body 1 constant, reduces energy loss, and thus achieves energy-saving effects. No additional electrical equipment is set in the capping freeze dryer body 1, which reduces the consumption of electric energy and further improves the energy-saving effect of the device. When the medicines are placed in the freeze drying chamber 6, cold air will escape, and part of the cold air will be stored in the protective box 2. Through the setting of the connecting pipe 7, the cold air can return to the freeze drying chamber 6, further reducing the escape of cold air and ensuring the constant temperature in the freeze drying chamber 6.
[0035] The above are only preferred embodiments of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
