Description

Technical Field

[0001] This utility model belongs to the technical field of ventilation devices, and more specifically, it relates to a greenhouse ventilation device. Background Technology

[0002] A greenhouse, also known as a hothouse, is a facility that allows light to pass through and provides insulation (or heating) for cultivating plants. During seasons unsuitable for plant growth, it provides a growing period and increases yield. It is primarily used for cultivating or raising seedlings of warm-weather vegetables, flowers, and trees during cold seasons. There are many types of greenhouses, which can be categorized based on different roof frame materials, lighting materials, shapes, and heating conditions. However, broadly speaking, a greenhouse is a type of greenhouse, and its purpose is also to maintain a certain temperature. Ventilation is an essential element in the use of greenhouses.

[0003] Based on the above, the inventors have discovered the following problems: Current ventilation devices are usually equipped with filters. In actual operation, these filters can effectively block solid particles, dust, and other impurities inside the greenhouse, causing them to remain in the filter position and preventing them from affecting the operation of the fan. However, if they are not cleaned for a long time, the accumulation of impurities will seriously affect the ventilation effect. Furthermore, cleaning the filter by disassembly is not only cumbersome but also requires stopping the operation of the fan, which will undoubtedly directly interfere with normal ventilation operations.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a greenhouse ventilation device in order to achieve a more practical purpose. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a greenhouse ventilation device to solve the problems of the current method of disassembling and cleaning the filter screen being cumbersome and requiring the fan to be stopped, which interferes with normal ventilation operations.

[0006] The purpose and effect of this utility model's greenhouse ventilation device are achieved through the following specific technical means:

[0007] A greenhouse ventilation device includes a greenhouse body, a ventilation window on one side of the greenhouse body, and a shell on the other side of the greenhouse body. A filter screen is fitted inside the top of the shell. A set of sliding grooves is formed on one side wall of the filter screen. A reciprocating screw and a sliding rod are provided in the sliding grooves. A slider is fitted on the reciprocating screw and the sliding rod. A scraper is provided on one side of the slider. A collection chamber is provided at the bottom of the shell. A pull-out box is provided in the collection chamber. An exhaust fan is provided at the bottom of the pull-out box. Several air outlets are provided on one side of the exhaust fan. A ventilation pipe is provided on one side of the shell and is connected to the greenhouse body.

[0008] Furthermore, a second filter screen is provided at the bottom of the pull-out box.

[0009] Furthermore, the reciprocating lead screw and the slider are connected by a reciprocating thread.

[0010] Furthermore, one side of the scraper is in contact with one surface of the filter screen.

[0011] Furthermore, the bottom of the housing is provided with a through groove, which is connected to the collection chamber.

[0012] Furthermore, a motor is installed inside the housing, and the output end of the motor is connected to a reciprocating lead screw drive.

[0013] Furthermore, a fan is installed inside the housing.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Through the cooperation between the housing, filter screen, slide groove, reciprocating screw, slide rod, slider, scraper and motor, when the exhaust fan is in use, when solid particles, dust and other impurities accumulate on the surface of the filter screen, the motor is started, which drives the reciprocating screw to rotate, and then drives the slider to move along the reciprocating screw and slide rod, and drives the scraper to clean along the surface of the filter screen, thus achieving an automatic cleaning effect, which is convenient and fast.

[0016] 2. By coordinating the collection chamber, fan, pull-out box, air outlet, and through slot, the fan is started. At this time, the fan discharges the air in the collection chamber, creating a negative pressure inside the collection chamber instantly. The through slot is connected to the inside of the shell, which facilitates the suction of scraped solid particles, dust, and other impurities from the through slot, and then pulls them to the pull-out box, where they fall onto the second filter screen. When cleaning is needed, the pull-out box can be pulled out for cleaning, greatly improving work efficiency. Attached Figure Description
