When the temperature decreases in winter, choose the plastic film with good transparency and strong insulation to cover the windows, doors and ceilings. When the outdoor temperature drops below zero, the windows and doors are covered with a layer of plastic film, and the ground is padded with rice chaff, rice straw or heat sources in the shed. However, attention should be paid to ventilation to prevent the occurrence of diseases. With the increase or decrease of temperature in spring and autumn, the plastic film should be opened or covered appropriately in time. Mainly do a good job of cooling in summer. When it is too hot, open all the windows and vents, turn on the electric fan to cool down when possible, and hang the sunshade net where the sun shines.
According to the management of medium-and long-term weather forecast, in case of continuous low temperature, the temperature of the mushroom house / shed should be kept above 8 °C ~ 10 °C. The main measures for heat preservation and warming include: thickening the roof cover at night; hanging blankets on doors; closing doors and windows for heat preservation in the morning and evening; opening doors and windows around noon in sunny days; opening only leeward vents for short-term ventilation in rainy and snowy weather; in cold or windy weather, close doors, windows and vents to prevent cold air from attacking. When the weather is fine, open the cover to increase the temperature of the light, when the light is strong, it is best to set up a sunshade net under the greenhouse film and above the bacterial stick to protect the light and heat. If there are heating facilities such as hot air stove, the temperature of the mushroom room / shed can be increased by heating, but attention should be paid to prevent the smoke from being discharged into the shed and cause poisoning. In addition, the ditch cleaning and drainage of the mushroom shed should also be done to reduce the humidity in the greenhouse in the rainy season and improve the mushroom quality.

Rain-proof shutters are used in computer rooms or other public places that need ventilation and rain protection, heat insulation and air flow regulation, and are composed of rain-proof blades with water collecting ditches, side frames with drip frames and streamlined regulating blades. It not only has the advantages of single-layer rain-proof shutters, but also the staff can adjust the opening of rain-proof shutters according to the indoor temperature or ventilation demand. Single-layer rain shutters are divided into vertical and horizontal, mainly used for large shopping malls, exhibition halls, garages and other places of the facade and top sunshade, also has the role of anti-theft insurance.
Hot plate hot fusion welding: thermoplastic welding equipment using surface heat conduction melting to weld the surface of plastic workpiece. It is not limited by the material and size of the parts, and the welding seal is good. It is suitable for the welding of large special-shaped workpieces such as airbag, dashboard, sunshade, car water dispenser, taillight, expansion water tank, brake oil cup and so on.
Seinfeld sun umbrellas are put away like ordinary umbrellas. The car sunshade is designed according to the shape of the car through the sun protection principle of the sun umbrella, covering from the front windshield to the rear windshield, which can effectively reduce the temperature in the car at high temperature.
Figure 3 is a schematic diagram of the patent application trend of the third-tier technology branch in the field of internal and external decoration. The growth trend of patent applications related to seat technology and headlamp technology is more obvious. The seat is the first component to evaluate whether the car is comfortable or not. Headlights are also an important part of safe driving. From the overall trend, the number of patent applications for the above technologies has increased rapidly since 2005. There is also a growth trend in dashboards and center consoles, rearview mirrors and bumpers, with slower growth in patent applications compared with seat and headlight technology. The number of technical applications such as sunshade panel and interior panel, radiator grille and spoiler is less, and the application trend is relatively flat.
