Description

Technical Field

[0001] The utility model relates to the technical field of cold storage temperature control, in particular to a cold storage dual-temperature dual-control device. Background Art

[0002] Cold storage is a type of refrigeration equipment. Cold storage refers to the use of artificial means to create an environment with different temperature or humidity from the outdoor environment. It is also a constant temperature and humidity storage equipment for food, liquids, chemicals, medicines, vaccines, scientific experiments and other items.

[0003] The dual-temperature dual-control device for cold storage can improve the precise control of the internal temperature of the cold storage. Cold air and normal temperature air are introduced into the air outlet through two air supply ducts respectively, and the wind speed inside the two air ducts is controlled to control the amount and speed of cold air entering the cold storage. However, the existing air outlet is fixed in size. When the wind force in one duct decreases and the wind force in the other increases, the size of the air outlet cannot change accordingly, resulting in a slow temperature control speed. To this end, we provide a dual-temperature dual-control device for cold storage to solve the above problems. Utility Model Content

[0015] 1. The utility model uses an adjustment plate installed in the air outlet head tube and friction wheels and friction plates installed on both sides of the air supply box A. When the airflow blown in from the air supply box A is accelerated and the airflow blown in from the air supply box B is reduced, the rotation speed of the friction wheel is accelerated, and the friction wheel pushes the through frame to move downward through friction contact with the friction plate, and pushes the adjustment plate to move downward.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-5 As shown, the utility model provides a technical solution: a dual-temperature dual-control device for a cold storage, comprising an air outlet head tube 1, an adjusting plate 3 is slidably inserted inside the air outlet head tube 1, an air supply box A2 is fixedly inserted on the upper surface of the air outlet head tube 1, and an air supply box B17 is fixedly inserted on the bottom surface of the air outlet head tube 1, different airflows are respectively introduced into the air supply box A2 and the air supply box B17, a long axis 4 is rotatably inserted inside the air supply box A2, and a plurality of leaf plates 5 are fixedly connected to one end of the long axis 4 located inside the air supply box A2, the front of the middle position of the air supply box A2 is arc-shaped, the leaf plates 5 and the long axis 4 are both located inside the arc-shaped structure of the air supply box A2, and the plurality of leaf plates 5 are distributed in a circular array around the axis of the long axis 4, and the extension line of the leaf plates 5 coincides with the axis of the long axis 4, and the airflow flowing from the upper end of the air supply box A2 flows from the rear of the long axis 4, and the airflow stably drives the long axis 4 to rotate by pushing the leaf plates 5.

[0025] The upper surface of the air outlet head tube 1 is slidably penetrated by a through frame 7, the bottom surface of the through frame 7 is fixedly connected to the upper surface of the adjustment plate 3, the upper surface of the air outlet head tube 1 is fixedly connected to a spring 6, the upper end of the spring 6 is fixedly connected to the through frame 7, the spring 6 is slidably sleeved on the outer surface of the through frame 7, the left and right ends of the long axis 4 are fixedly sleeved with friction wheels 9, the rear of the two friction wheels 9 are in friction contact with friction plates 8, when the friction wheel 9 does not rotate, the spring 6 has a tendency to push the through frame 7 upward, when the friction wheel 9 rotates, the friction force between the friction plate 8 and the through frame pushes the through frame 7 to compress the spring, as the friction wheel 9 rotates faster, the friction plate 8 is pushed downward, the lower end of the friction plate 8 is in contact with the through frame The upper back side of 7 is fixedly connected, and one end of the friction plate 8 located below the friction wheel 9 is bent forward. The two friction wheels 9 are coaxially arranged with the long axis 4. When the airflow blown in from the air supply box A2 is accelerated and the airflow blown in from the air supply box B17 is reduced, the rotation speed of the friction wheel 9 is accelerated, pushing the adjustment plate 3 to move downward. The faster the airflow provided in the air supply box A2, the greater the distance the adjustment plate 3 moves downward, so that the air outlet range on the upper side is larger, while the air outlet range on the other side is reduced. The range of the air outlets on the upper and lower sides can be changed according to the air outlet speeds in the air supply boxes A2 and B17. When the air inlet speed in the air supply box A2 increases, the air inlet speed in the air supply box B17 decreases.

[0026] A toothed plate 10 is slidably inserted on the right side of the air outlet head tube 1, and a plurality of gears 11 are meshed in front of the toothed plate 10. The left end of the gear 11 rotates and passes through the right side of the air outlet head tube 1. One end of the gear 11 located inside the air outlet head tube 1 is fixedly sleeved with a wind plate 12. A bending transmission box 13 is fixedly installed on the upper surface of the air outlet head tube 1. The right end of the long axis 4 is fixedly connected to the upper input end of the bending transmission box 13. A horizontal frame 15 is fixedly installed on the upper end of the toothed plate 10. An insertion shaft 14 is slidably inserted inside the horizontal frame 15. The insertion shaft The left end of 14 is fixedly connected with a rotating plate 16, and the left side of the other end of the rotating plate 16 is fixedly connected to the output end of the bending transmission box 13. When the long shaft 4 rotates, the rotating plate 16 is driven to rotate through the bending transmission box 13. The plug shaft 14 slides in the horizontal frame 15 as the rotating plate 16 rotates, and can reciprocate to drive the tooth plate 10 up and down. The gear 11 drives the wind plate 12 to swing back and forth by meshing with the tooth plate 10, so that the air outlet angle of the air outlet head tube 1 is continuously changed, thereby increasing the blowing angle of the cold air mixture.

[0027] Working principle: When air is blown into the air supply box A2, the air flow drives the long shaft 4 and the friction wheel 9 to rotate by pushing the leaf plate 5. The friction wheel 9 pushes the through frame 7 to compress the spring 6 downward by friction contact with the friction plate 8, and pushes the adjustment plate 3 to move downward. The air flow provided by the air supply box A2 and the air supply box B17 flows out from the front end of the air outlet head tube 1. The long shaft 4 drives the rotating plate 16 to rotate through the bending transmission box 13. The plug shaft 14 drives the tooth plate 10 to move up and down reciprocatingly by sliding in the horizontal frame 15. The gear 11 drives the wind plate 12 to swing by meshing with the tooth plate 10 moving up and down, constantly changing the direction of the air outflow from the front end of the air outlet head tube 1, and increasing the range of the wind spray. When the airflow blown in from the air supply box A2 is accelerated and the airflow blown in from the air supply box B17 is reduced, the rotation speed of the friction wheel 9 is accelerated, and the friction wheel 9 pushes the frame 7 to move downward through friction contact with the friction plate 8, and pushes the adjustment plate 3 to move downward. The faster the airflow provided in the air supply box A2, the greater the distance the adjustment plate 3 moves downward, so that the air outlet range on the upper side is larger, while the air outlet range on the other side is reduced. Conversely, after reducing the airflow blown into the air supply box A2 and increasing the airflow blown into the air supply box B17, the adjustment plate 3 moves upward, and the air outlet range below the adjustment plate 3 is increased, so that the air outlet range on both sides of the adjustment plate 3 changes with the air outlet volume.
