Description

Technical Field

[0001] This utility model relates to the field of purification equipment technology, and more specifically to an FFU high-efficiency air supply unit. Background Technology

[0002] Fan filter units (FFUs) are, more precisely, modular terminal air supply devices that are self-powered and have filtration capabilities. FFUs are widely used in various cleanrooms in industries including electronics and biomedicine, and are an essential component of cleanroom air conditioning systems.

[0003] To prevent the internal centrifugal fan from becoming contaminated, existing FFU (Fan Filter Unit) systems typically add a screen to the casing to block a large amount of dust from contacting and settling on the centrifugal fan. However, while this method can block dust from the centrifugal fan, after a period of operation, because the screen faces directly onto the casing, the dust adhering to the screen becomes severe, resulting in a thick layer of dust. Since the screen is located at the air inlet, it will obstruct the airflow, making it difficult to maintain efficient airflow for a long time and affecting the indoor cleanliness.

[0004] Based on the above background, an FFU (Fan Filter Unit) high-efficiency air supply unit is proposed to solve the problem. Utility Model Content

[0005] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0006] The purpose of this invention is to overcome the above-mentioned shortcomings and provide an FFU (Fan Filter Unit) with high efficiency air supply.

[0007] To achieve the above objectives, the technical solution of this utility model is: an FFU high-efficiency air supply unit, comprising: a housing, a blocking device, a partition screen, a centrifugal fan, and an air supply plate. The air supply plate is installed on the lower side of the housing, the centrifugal fan is inserted into the housing and located above the air supply plate, the partition screen is installed on the upper side of the housing and located above the centrifugal fan, and the blocking device is disposed on the housing and located outside the partition screen. The blocking device includes a support frame, a first connecting block, a cylinder, a second connecting block, a baffle, and a hinge. The first connecting block is installed on the side of the support frame, the second connecting block is rotatably connected to the side of the baffle, the two sides of the cylinder are rotatably connected to the first connecting block and the second connecting block respectively, the baffle is connected to the baffle via a hinge, and the support frame is disposed on the housing and located outside the partition screen.

[0008] Preferably, the area of ​​the baffle is greater than or equal to that of the support frame.

[0009] Preferably, the cylinder body is rotatably connected to the second connecting block via a rotating shaft.

[0010] Preferably, the cylinder rod is rotatably connected to the first connecting block via a rotating shaft.

[0011] As a preferred option, a handle is installed on the casing.

[0012] As a preferred option, a diffuser is provided on the air supply panel.

[0013] Preferably, a mounting plate is installed inside the casing, and the centrifugal fan is mounted on the mounting plate.

[0014] Preferably, a filter is installed inside the casing and located below the centrifugal fan.

[0015] Preferably, the side of the casing is fitted with a perforated mounting plate.

[0016] The beneficial effects of this utility model are as follows: This utility model uses a cylinder to pull a baffle, which rotates under the action of a hinge, turning towards the support frame until it covers the support frame. This process, through the baffle's rotation, blocks the mesh, isolating it from the outside world when not in operation, thus reducing the rapid dust accumulation on the mesh. It also serves to block dust from the internal fan, thereby maintaining efficient air supply for a longer period of time during operation, improving the air supply effect and the cleanliness of the space.
