Description

Technical Field

[0001] The invention relates to the technical field of transfer boxes, in particular to a ventilated, cooled and sterilized transfer box. Background Art

[0002] Cordyceps sinensis is suitable for growing in cold and dry areas such as the Northeast and the Qinghai-Tibet Plateau. It is a unique species that grows in the high-altitude cold areas of the Qinghai-Tibet Plateau. It is referred to as Cordyceps. Cordyceps is a typical subtropical plant that prefers a high humidity environment. Humidity is one of the most important environmental factors for the growth and development of Cordyceps. The humidity requirement of Cordyceps is generally between 70% and 80%. If the environmental humidity is too low, Cordyceps will not be able to absorb water normally and affect its growth and development. An overly humid environment will cause bacteria to breed, which will have an adverse effect on the growth of Cordyceps sinensis. In addition, the humidity requirements are different at different growth stages of Cordyceps. For example, during the mycelium growth stage, the humidity should be maintained between 80% and 95% to ensure the healthy growth of the mycelium.

[0003] At the same time, the temperature requirement for artificial cultivation of Cordyceps is relatively narrow, generally between 20℃ and 25℃. This is because Cordyceps needs an environment with suitable temperature and high relative humidity to grow well. Within this temperature range, Cordyceps can better absorb nutrients and enhance its own immunity. The temperature also needs to change at different growth stages of Cordyceps. For example, during the mycelium growth stage, the temperature should be kept at around 20℃; during the fruiting body formation and development stage, the temperature should be gradually increased to 24℃-25℃.

[0004] Therefore, the requirements for the soil for cultivating Cordyceps sinensis are relatively stringent. The soil for cultivating Cordyceps sinensis needs to be sterilized with high-temperature steam in advance to ensure the qualified rate of the medicinal properties of Cordyceps sinensis. Then, the soil after high-temperature steam sterilization needs to be placed in a transfer box for ventilation, dehumidification, cooling and sterilization, and the treated soil is placed in the original clean room for cultivating Cordyceps sinensis to cultivate Cordyceps sinensis. The transfer box is set up to prevent the heat and humidity emitted by the soil after high-temperature steam sterilization from affecting the temperature and humidity of the original clean room for cultivating Cordyceps sinensis.

[0005] Existing transfer boxes can be ventilated, dehumidified, cooled and sterilized. For example, a Chinese patent with authorization announcement number CN214616185U discloses a clean room article transfer device, including a box body, an inner window, an outer window and a clean device; the clean device includes a high-level air filter, a diverter plate, a nozzle, a storage plate and a primary filter arranged in sequence from top to bottom; the air outlet of the high-level filter is downward and is provided with a refrigeration plate, and the diverter hole is provided on the diverter plate. The high-level filter is connected with the diverter hole of the diverter plate through an air inlet channel so that the cold air generated by it can cover the box body from the top; the storage plate is arranged in the middle and lower part of the box body, and the primary filter includes a filter, an exhaust fan and a filter screen; the lower part of the storage plate is connected with the filter through the air outlet channel, the lower part of the filter is connected with the air inlet of the exhaust fan, and the air outlet of the exhaust fan faces the filter screen.

[0006] The above-mentioned public document processes the air intake structure after filtration by the advanced filter. There are two improvements here. First, a diverter plate is arranged at its lower part. The diverter plate can evenly distribute the gas generated by it in the box by setting diverter holes, so that the intake air flow can enter the box in a covered state; second, a cooling plate is arranged at the air intake. The purpose of the arrangement is to make the intake air flow cold air, that is, cold air with a temperature lower than that of the air in the box. The cold air falls and moves the air in the box downward, thereby achieving high cleaning efficiency.

[0007] In the above-mentioned public documents, the air entering the box is filtered by an advanced filter to block aerosols and bacteria in the air. However, in actual use, as the usage time increases, the aerosols and bacteria blocked by the advanced filter will increase, and the blockage of the filter by aerosols and bacteria will become more and more serious. When the blockage is serious, it will seriously hinder the air from entering the box, thereby affecting the normal use of the transfer box. How to replace the filter in time to prevent aerosols and bacteria from seriously hindering the air from entering the box is a technical problem that needs to be solved. Summary of the invention

A clean component is provided at the air inlet of the transfer box, and the cleaning component is used to ensure the filtering effect of the air. The clean component includes a filter and a measuring unit for detecting the pressure difference between the air inlet and air outlet of the filter.
