Description

Technical Field

[0001] The present invention relates to the technical field of indoor pressure regulation, in particular to an intelligent room pressure difference control system. Background Art

[0002] Air always flows from areas with high absolute pressure differentials to areas with low absolute pressure differentials. Therefore, it is necessary to ensure that the absolute pressure differential in rooms with higher cleanliness levels is higher, and the absolute pressure differential in rooms with lower cleanliness levels is lower. In this way, when the clean room is operating normally or the room's airtightness is damaged (such as when a door is opened), air can flow from the high-cleanliness area to the low-cleanliness area, so that the cleanliness of the high-cleanliness level room is not contaminated or affected by the air in the low-cleanliness level room. Because this kind of contamination and cross-contamination is invisible, it is often ignored by many people. At the same time, this kind of contamination is very serious and irreversible. Once contaminated, it will cause endless troubles.

[0003] Currently, most systems used for indoor pressure difference regulation use fixed directional exhaust vents and fixed directional exhaust vents. Not only can the position of the vents not be adjusted, but the vents are exposed to the outside when not in use, which increases the amount of dust collected inside the vents and reduces the cleanliness of the vents. In addition, the traditional adjustment mechanism cannot be adjusted between positive and negative pressures at will, and it only has the function of adjusting the air volume, and its functionality is also very simple. Summary of the Invention

The horizontal connecting pipe is composed of four horizontal air guide boxes 7 assembled and fixed. A bottom regulating air outlet 8 is provided on the lower surface of the horizontal air guide box 7. The electrically controlled regulating air valve and the ultraviolet LED lamp 5 are installed inside the bottom regulating air outlet 8. Magnetic control components that cooperate with the electrically controlled regulating air valve are fixedly installed on the inner walls on both sides of the bottom regulating air outlet 8.

[0027] The touch panel 3 with a built-in pressure difference monitoring module is an existing technology. The indoor pressure can be monitored through the touch panel 3, and then the indoor pressure difference can be adjusted and controlled manually or automatically. The circuit and system are all existing technologies.

[0028] In order to cooperate with the lifting and lowering adjustment, the inner wall of the horizontal air guide box 7 is provided with outward-bending lateral curved covers 9 on both sides of the bottom adjustment air outlet 8, and the lateral curved covers 9 are movably equipped with side adjustment screws 10 inside.

[0029] In order to cooperate with the lifting and lowering adjustment, the electrically controlled regulating air valve includes an internal thread lifting block 11 threadedly sleeved on the outside of the side adjusting screw 10, an internal lifting frame 12 fixed on the inside of the internal thread lifting block 11, a bottom closed guide plate 13 fixed on the bottom of the internal lifting frame 12, an internal guide plate 14 elastically assembled on the inside of the internal lifting frame 12 and a drive motor 15 fixed to the upper end of the horizontal air guide box 7 through an external cover.

[0030] In order to cooperate with the lateral transmission, gear transmission components 16 for connecting the side adjustment screw 10 and the drive shafts on both sides of the drive motor 15 are movably assembled on both sides of the outer cover.

[0031] The gear transmission assembly 16 is composed of two mutually meshing bevel gears, and the two bevel gears are axially mounted on the top of the side adjustment screw 10 and the top of the outer drive shaft of the drive motor 15 respectively.

[0032] In order to cooperate with lateral adsorption and flip adjustment, the internal guide plate 14 includes a central guide plate 17 with an integral structural assembly axis on both sides, a sliding extension plate 18 slidably assembled on both sides of the upper surface of the central guide plate 17, an iron adsorption tube 19 fixed on the top outer side of the sliding extension plate 18, and an elastic torsion spring 20 installed on the lower surface of the central guide plate 17.

[0033] Lateral adjustment grooves for slidingly assembling the sliding extension plate 18 are provided on both sides of the upper surface of the central guide plate 17, and a bottom slide groove is provided on the inner side of the lateral adjustment groove. The sliding extension plate 18 is inserted into the bottom slide groove through the bottom adjustment slider and slidably assembled with the inside of the lateral adjustment groove.

[0034] In order to cooperate with internal assembly, lateral mounting blind holes for installing the assembly shaft are symmetrically opened on the inner walls on both sides of the internal lifting frame 12, and lateral mounting slots for installing the elastic torsion spring 20 are opened on the inner walls on both sides of the internal lifting frame 12 below the lateral mounting blind holes.

[0035] In order to cooperate with the ultraviolet irradiation sterilization of the incoming and outgoing air, the ultraviolet LED lamp 5 is fixedly installed on the upper surface of the bottom closed guide plate 13 and on both sides of the internal lifting frame 12.

[0036] In order to cooperate with the lateral assembly and electromagnetic control, the magnetic control assembly includes an arc-shaped assembly frame 22 fixed on both sides of the bottom regulating air outlet 8 and a bar-shaped electromagnet 23 fixed inside the arc-shaped assembly frame 22.

[0037] Working principle: the driving motor 15 drives the side adjusting screw 10 to rotate, thereby controlling the internal thread lifting block 11 to rise and fall inside the lateral curved cover 9, and the internal lifting frame 12 drives the bottom closed guide plate 13 to rise and fall below the bottom adjusting air outlet 8. When the magnetic control components are inserted on both sides of the internal guide plate 14, when negative pressure is needed, the magnetic control component at the windward end is energized and started, and the iron adsorption tube 19 on the corresponding surface of the internal guide plate 14 is magnetically attracted. Then the driving motor 15 drives the side adjusting screw 10 to flip, thereby controlling the internal thread lifting block 11, the internal lifting frame 12, the bottom closed guide plate 13 and the internal guide plate 14 to rise. At this time, a slope is generated on the windward side, and then the sliding extension plate 18 slides on one side of the upper surface of the central guide plate 17, thereby forming a negative pressure at the bottom adjusting air outlet 8 position; on the contrary, when positive pressure is needed at the bottom adjusting air outlet 8 position, it is only necessary to start the magnetic control component at the leeward side position, and the other operating methods are the same as above.

[0038] In order to improve the stability of the internal guide plate 14 inside the horizontal air guide box 7 after it is lifted, an internal stabilizing bracket 24 for improving the stability of the internal guide plate 14 is fixedly installed on the top surface of the horizontal air guide box 7 just above the bottom regulating air outlet 8.

[0039] An ultraviolet sterilization lighting fixture or a temperature regulating device can also be installed on the inner side of the internal stabilizing bracket 24. Both ultraviolet sterilization lighting fixture and temperature regulating device are prior art. At the same time, an elastic shock-absorbing pad is installed at the bottom of the internal stabilizing bracket 24 to improve shock absorption.

[0040] In order to improve functionality, an LED flat panel light 25 for coordinated lighting is fixedly mounted on the lower surface of the bottom closed guide plate 13 .

[0041] Mounting the LED flat panel light 25 on the lower surface of the bottom closed guide plate 13 not only improves the overall functionality, but also indirectly improves the heat dissipation of the LED flat panel light 25. The LED flat panel light 25 is a prior art.

[0042] The intelligent room pressure difference control system of the present invention connects the first air duct 1 and the second air duct 2 through a horizontal connecting pipe in the room, and uses the electrically controlled regulating air valve located on the horizontal connecting pipe to adjust the position of the air outlet and the positive and negative pressure of the air outlet, so that the air outlet position can be freely adjusted as needed, and the operation mode is more diverse; the electrically controlled regulating air valve adopts a lifting structure design, which can automatically close the bottom regulating air outlet 8 when idle, so as to maintain the airtightness of the air outlet position, avoid internal dust collection and secondary dust, and greatly improve safety and durability; by fixing the ultraviolet LED sterilization lamp 21 on the upper surface of the bottom closed guide plate 13 and fixing the LED flat panel lamp on the lower surface of the bottom closed guide plate, the sterilization performance of the air circulation state can be improved, and the functionality of the entire system can be improved; by using the magnetic control components located on the inner walls on both sides of the bottom regulating air outlet in combination with the electrically controlled regulating air valve, the angle of the internal guide plate can be adjusted by lifting and electromagnetic adsorption. The operation is very simple and convenient, and the pressure difference adjustment is more convenient.
