Technical Field
[0001] The utility model relates to a swirl air outlet for a clean room, belonging to the technical field of clean room purification. Background Art
[0002] In clean workshop purification air conditioning systems, swirl vents are often used.
[0003] In the prior art, the traditional swirl vent is generally fixed on the ceiling of the clean room, and the airflow is rotated and diffused into the clean room through the guide blades of the swirl vent to achieve the purpose of air supply. Specifically, the guide blades of the swirl vent convey the airflow in a fixed manner. During the air supply process, the airflow is sent out in a spiral shape through the guide plate of the blade, resulting in a very high induction ratio, so that the air supply is quickly mixed with the surrounding indoor air. However, there is a problem that the angle of the blade cannot be adjusted during operation, which makes it difficult to eliminate the local vortex in the clean room, causing the temperature and humidity in the local area to not meet the standards, affecting the stability of product quality; on the other hand, the treatment of temperature and humidity is generally solved by increasing the number or layout of swirl vents, which will lead to an increase in procurement costs and operating costs.

[0007] Preferably, a control component connected to the guide plate angle adjustment mechanism signal is installed on the outer wall of the closing plate, and the control component is also connected to the sensor interface signal, and the sensor interface is externally connected to a temperature and humidity sensor. The temperature and humidity can be detected by the temperature and humidity sensor, and the signal received by the temperature and humidity sensor is transmitted to the control component through the sensor interface, and the control component controls the guide plate angle adjustment mechanism to adjust the angle of the guide plate.

[0016] The utility model is further described in detail below in conjunction with embodiments and specific implementation methods.
[0017] like Figure 1-3As shown, a swirl air outlet for a clean room includes a closing plate 1, a guide plate 2 and a guide plate angle adjustment mechanism, the guide plate angle adjustment mechanism is fixed on the inner wall of the closing plate 1, the guide plate 2 is installed on the guide plate angle adjustment mechanism, and a control component 5 connected to the guide plate angle adjustment mechanism signal is installed on the outer wall of the closing plate 1, the control component 5 is also connected to the sensor interface 4 signal, and the sensor interface 4 is externally connected to a temperature and humidity sensor.
[0018] During operation, the temperature and humidity can be detected by the temperature and humidity sensor. The signal received by the temperature and humidity sensor is transmitted to the control component 5 through the sensor interface 4. The control component 5 controls the guide plate angle adjustment mechanism to adjust the angle of the guide plate 2 to circulate and purify the air in the entire clean room. The control method of adjusting the angle of the guide plate 2 according to the signal received by the temperature and humidity sensor by the control component 5 is implemented by the existing technology and does not fall within the scope of protection of this application.
[0019] The guide plate angle adjustment mechanism includes a telescopic cylinder 3, a support frame 6, an extension rod 7 and a telescopic sleeve 8. The outer end of the support frame 6 is fixed on the inner wall of the closing plate 1, and a cylinder is fixed at the center of the inner end of the support frame 6. The telescopic cylinder 3 is fixed on the cylinder. The output end of the telescopic cylinder 3 is connected to the telescopic sleeve 8. The telescopic sleeve 8 is circumferentially installed with multiple extension rods 7. A pair of push plates 9 are provided at the end of the extension rod 7. Several fan-shaped guide plates 2 are circumferentially connected to the cylinder. Specifically, one side of each guide plate 2 is rotatably connected to the cylinder through a rotating shaft 10, and the other side of each guide plate 2 is correspondingly located between a pair of push plates 9 on an extension rod 7.
[0020] The telescopic cylinder 3 controls the telescopic sleeve 8 to work, so that the telescopic sleeve 8 exerts a force on the extension rod 7. Under the force, the extension rod 7 pushes or pulls the guide plate 2 through the push plate 9. The guide plate 2 rotates around the rotating shaft 10 to adjust the angle. Each time the telescopic sleeve 8 is extended and retracted, the guide plate 2 rotates an angle.
[0021] The closing plate 1 comprises Figure 1 The snap-on or Figure 2 In the cylindrical type shown, the cylindrical closing plate 1 is cylindrical, and the snap-fit type is a cylindrical closing plate 1 with snap-fit structures added at both ends.
[0022] like Figure 5As shown, the swirl vents for clean rooms are installed on the ceiling of the new energy clean room in a snap-on manner. The return air vents are located on both sides of the new energy clean room, and thin wires connect the control components and the temperature and humidity sensors. Due to the use of the form of upper delivery and side return, air vortices are easily generated in the clean area, resulting in the failure of the temperature and humidity in the local area to meet the requirements. In order to reduce or eliminate the existence of the vortex zone, the temperature and humidity sensor is arranged in the middle of the clean area where the vortex zone is easily generated. The temperature and humidity sensor detects the temperature and humidity in the vortex zone. If the temperature and humidity requirements are not met, the temperature and humidity sensor controls the telescopic cylinder to work, and the telescopic cylinder controls the telescopic sleeve to work, so that the telescopic sleeve exerts force on the extension rod. Under the force, the guide plate is pushed and the diffusion angle is adjusted to 45°. The airflow organization in the vortex zone is changed again, thereby achieving the purpose of reducing or eliminating. If the 45° angle blade cannot meet the requirements, the telescopic sleeve continues to exert force on the extension rod, and continues to push the guide plate to adjust the angle until the temperature and humidity meet the requirements, and the telescopic sleeve stops exerting force.
[0023] All the components mentioned above are prior art, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.
[0024] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
