Description

Technical Field

[0001] The utility model relates to the technical field of greenhouse, in particular to a heating device for a greenhouse with a stable temperature control structure. Background Art

[0002] A greenhouse, also known as a hothouse, is a facility that can transmit light, keep warm or heat up, and is used for cultivating plants. In seasons when it is not suitable for plant growth, it can provide a growth period in the greenhouse and increase yields, and is mostly used for cultivating or raising seedlings of heat-loving vegetables, flowers, forest trees, etc. in low-temperature seasons.

[0003] In this regard, Chinese Patent Application No.: CN202021928499.X discloses a greenhouse oxygen supplement and heating warm air device, including a greenhouse body. Water tanks are fixedly connected to both sides of the greenhouse body. Blower boxes are fixedly connected to both sides of the greenhouse body and on the back of the water tanks. A blower is fixedly connected to the inner cavity of the blower box through a bracket. A heating plate is fixedly connected to the inner cavity of the blower box and inside the blower. A filter plate is arranged inside the blower box and inside the heating plate. Through the settings of the greenhouse body, water tanks and blower boxes, a greenhouse oxygen supplement and heating warm air device is jointly constructed. Among them, through the settings of threaded grooves, threaded rods, turntables and turning handles, the clamping block can be driven to move up and down in the fixed groove, so that the filter plate in the blower box can be easily replaced, which is convenient for users to replace or clean it. The cooperation of the above structures solves the problem that the greenhouse oxygen supplement and heating warm air device is not easy to disassemble.

[0004] This device heats the inside of the greenhouse body through the cooperation of a blower and a heating plate. However, the position where the hot air blows out is fixed. Since the density of hot air is small and its weight is light, while the original air temperature inside the greenhouse body is low, the density is large and the weight is heavy. Therefore, the hot air rises, and the cold air descends, so that the hot air will gather at the upper end inside the greenhouse body first, and it will slowly fill the entire greenhouse body over time, resulting in a slow speed of increasing the heat inside the greenhouse body.

[0005] Therefore, in order to solve the above problems, a heating device for a greenhouse with a stable temperature control structure is proposed. Summary of the Utility Model

[0006] The purpose of the present utility model is to provide a heating device for a greenhouse with a stable temperature control structure, so as to solve the problem mentioned in the above background technology that the device in the prior art heats the inside of the greenhouse main body through the cooperation of a fan and a heating plate. However, the position where the hot air blows out is fixed, and since the density of the hot air is small and the weight is light, while the original air temperature inside the greenhouse main body is low, the density is large and the weight is heavy, so the hot air rises and the cold air descends, causing the hot air to gather first at the upper end inside the greenhouse main body and only slowly filling the entire greenhouse main body over time, resulting in a slow speed of increasing the heat inside the greenhouse main body.

[0015] The utility model is provided with a temperature control mechanism. When the heating wire and the exhaust fan are started, the exhaust fan can suck the air in the greenhouse main body from the upper end into the movable block. The filter screen can filter the incoming air, and the heating wire can heat the incoming air, so that hot air flows inside the movable block.
