Description

Technical Field

[0001] This utility model relates to the field of cold storage technology, and more specifically, to a cold storage humidity control device. Background Technology

[0002] Cold storage is a facility for storing goods at low temperatures, and humidity control is crucial. Too high or too low humidity may have an adverse effect on the quality and stability of the stored goods.

[0003] Chinese utility model patent with announcement number CN219454394U describes a humidity regulating device for a cooling warehouse, including a fixed pipe with an mounting plate installed on it. A fixing ring is installed on one end of the inner wall of the fixed pipe, and a baffle is installed on the inner wall of the fixing ring. A fixing hole is opened on the outer wall of the baffle, and a support rod is rotatably installed in the fixing hole. Both ends of the support rod pass through the fixing hole and are installed on the inner wall of the fixing ring.

[0004] The above solution addresses the problem that when it is necessary to release humid air from inside the cold storage, the baffle can open the fixed pipe, allowing the interior of the cold storage to connect with the outside through the fixed pipe. When it is not necessary to release humid air from inside the cold storage, the baffle automatically seals the fixed pipe, preventing the cold air inside the cold storage from being released to the outside. During use, there is no need for staff to manually open or seal the fixed pipe, making it more convenient to use.

[0005] This application provides another technical solution to this technical problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a humidity control device for cold storage.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0008] A humidity control device for cold storage includes a pipe body, a drum fan driven to rotate by a motor inside the pipe body, a support rod fixedly installed at the output end of the motor, the support rod and the drum fan being slidably connected, a control component for pushing the drum fan to slide in the pipe body, and a sealing component that abuts against the drum fan fixed inside the pipe body.

[0009] The present invention is further configured such that: the support rod is provided with a spring, the two ends of the spring are respectively connected to the drum fan and the support rod; the control component includes a magnetic ring and an electromagnet for attracting the magnetic ring; the magnetic ring is fixedly installed on the drum fan; and the electromagnet is fixedly connected to the tube body.

[0010] The present invention is further configured such that: a plurality of electromagnets and magnetic rings are provided, and the plurality of electromagnets and magnetic rings are arranged in a ring at intervals.

[0011] The present invention is further configured such that: the sealing component includes a support plate, and the support plate has a guide port corresponding to the drum fan.

[0012] The present invention is further configured such that the support plate is fixed with a sealing gasket that contacts the drum fan.

[0013] The present invention is further configured such that a humidity and temperature sensor is provided on the side of the support plate away from the drum fan.

[0014] In summary, this utility model has the following beneficial effects:

[0015] When dehumidification is required, the electromagnet is energized to attract the magnetic ring, causing the drum fan and support plate to separate and allowing the drum fan to rotate. The drum fan rotates under the action of the motor, causing the humid gas in the cold storage to flow out. After the humid gas is completely removed, the electromagnet is de-energized, and the drum fan will return to its original position due to the spring. The drum fan and support plate together block the gas flow, thus conveniently completing the operation of removing moisture from the cold storage. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "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 the present utility model and simplifying the description, 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 the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] like Figure 1 and Figure 2 , Figure 3 as well as Figure 4 As shown, this application provides a cold storage humidity control device, including a pipe body 1. Air inside the cold storage can flow out to the outside through the pipe body 1. A motor 2 is fixedly installed inside the pipe body 1, and a support rod 3 is fixed to the output end of the motor 2. A drum fan 4 is slidably installed on the support rod 3. When the motor 2 is powered on, the support rod 3 will drive the drum fan 4 to rotate together. The rotating drum fan 4 will accelerate the air flow, so that the air inside the cold storage can be discharged to the outside more quickly, thus accelerating the drying inside the cold storage.

[0024] like Figure 3 , Figure 4 as well as Figure 5 As shown, the pipe body 1 is fixedly connected to a sealing component, which includes a support plate 5. The support plate 5 forms a guide port 8 corresponding to the drum fan 4. At the same time, a sealing gasket 6 is fixed to the support plate 5. The support rod 3 is equipped with a spring 7. The two ends of the spring 7 are connected to the drum fan 4 and the support rod 3 respectively. In the initial state, the drum fan 4 will contact the sealing gasket 6 under the action of the spring 7, thereby blocking the guide port 8, so that the air in the cold storage cannot flow through the guide port 8, ensuring the heat preservation effect of the cold storage. A humidity and temperature sensor 11 is set on the side of the support plate 5 away from the drum fan 4. This setting can detect the humidity and temperature in the cold storage, thereby helping the operator to perform the exhaust operation of the cold storage.

[0025] like Figure 3 , Figure 4 as well as Figure 5As shown, the pipe body 1 is equipped with a control component, which includes a magnetic ring 9 and an electromagnet 10 for attracting the magnetic ring 9. The magnetic ring 9 is fixedly installed on the drum fan 4, and the electromagnet 10 is fixedly connected to the pipe body 1. When exhaust is required, the electromagnet 10 is energized, and the electromagnet 10 will attract the magnetic ring 9, causing the drum fan 4 to be subjected to a force away from the support plate 5. The drum fan 4 will overcome the elastic force of the spring 7 to release the contact with the sealing gasket 6 and release the blockage of the guide port 8. At this time, the motor 2 is energized, and the motor 2 will drive the drum fan 4 to rotate, so as to actively guide the cold storage air to flow to the outside.

[0026] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
