Ventilating equipment for greenhouse

Abstract

The invention discloses ventilating equipment for a greenhouse. The ventilating equipment comprises a device shell, wherein a water tank is arranged at the left end of a cavity, a first pipeline is formed in the bottom end of a water storage cavity, and a steam bin is arranged on the right side of the water tank; a first heating pipe is mounted at the bottom of the inner wall on the right side ofthe steam bin, a second heating pipe is mounted at the top of the inner wall on the right side of the steam bin, and a suction fan is arranged on the right side of the steam bin; and spraying heads are uniformly mounted on the surface of a fifth pipeline, a switch button is arranged on the front surface of the device shell, a power plug is arranged at the bottom end of the left side of the deviceshell, and a water hole cover sleeves the top end of a water filling hole. According to the ventilating equipment, water steam and air are sprayed out by the suction fan through the spraying heads, sothat air circulation in the plant greenhouse is enhanced, plants in the plant greenhouse are continuously irrigated, the quality of the plants in the greenhouse is improved, and the labor intensity of a user in a planting process is alleviated.

Description

technical field [0001] The invention relates to the technical field of ventilation equipment, in particular to a ventilation equipment for greenhouses. Background technique [0002] In order to improve the growth quality of crops or plants, greenhouses are more and more widely used. The temperature and humidity in the greenhouses are precisely controlled, which is very beneficial to the growth of plants. However, in order to control the temperature and humidity more accurately, the greenhouses usually In a closed space, sufficient oxygen is required for plant growth, so the greenhouse needs to be used together with ventilation equipment to grow good crops, but the existing ventilation equipment generally uses exhaust fans to generate negative air pressure in the greenhouse, so that the air pressure in the greenhouse is low. Based on the external air pressure, the external air is transported to the greenhouse. This method requires a large number of negative pressure fans to w...
