DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the drawings of the specification.

[0025] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0026] Secondly, as used herein, "an embodiment" or "embodiments" refer to specific features, structures, or characteristics that may be included in at least one implementation manner of the present invention. The phrase "in an embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments.

[0027] Thirdly, the present invention is described in detail in conjunction with schematic diagrams. When detailing the embodiments of the present invention, for the sake of convenience in explanation, the cross-sectional views showing the device structure are locally enlarged out of the general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0028] Embodiment 1, referring to Figures 1 to 2 , which is the first embodiment of the present invention, provides a flow regulating device, including a sealed container 100 in which a liquid is placed, and the volume of the liquid changes simultaneously with the temperature; a ventilation floor 200, including a first floor 201 and a second floor 202, the first floor 201 is disposed at the end of the second floor 202, and the ventilation holes of the first floor 201 and the second floor 202 are evenly staggered, and the passage between the ventilation holes of the first floor 201 and the ventilation holes of the second floor 202 is a ventilation passage; an adjusting mechanism 300, the adjusting mechanism 300 is connected to both the sealed container 100 and the ventilation floor 200 at the same time, and the adjusting mechanism 300 changes the cross-sectional area of the ventilation passage through the change in the volume of the liquid.

[0029] It should be noted that the highly elastic polymer film 101c is tightly attached to the inner wall of the container, so the container is fully sealed without any gaps for water to leak or evaporate;

[0030] When the liquid expands, it drives the first piston 101d to work through the deformation of the highly elastic polymer film 101c. Therefore, the sealing performance between the first piston 101d and the inner wall of the first connection port 101b extending outside the container does not need to be considered. Only a proper gap is required to ensure that the piston can move smoothly, and too precise machining is not required. Since the ventilation floor 200 is horizontally placed, when the second floor 202 moves, it only needs to overcome the friction between the wind shielding plates. The ventilation floor 200 is a thin plate with many through holes and has a very small mass, so the friction is very small, and the driving force generated by the liquid expansion is completely sufficient to drive its movement. Please refer to the following figure for details.

[0031] Specifically, the sealed container 100 includes a first container 101. The first container 101 includes a first cavity 101a and a first connection port 101b provided at the end of the first cavity 101a. The first cavity 101a and the first connection port 101b are integrally formed.

[0032] Wherein, a highly elastic polymer film 101c is provided at the junction of the first connection port 101b and the first cavity 101a. It should be noted that the first cavity 101a and the highly elastic polymer film 101c jointly construct a sealed chamber environment.

[0033] Furthermore, a first piston 101d is provided in the first connection port 101b. The first piston 101d includes a first contact block and a first connecting rod fixedly connected to the first contact block.

[0034] Furthermore, one end of the first contact block is in contact with the highly elastic polymer film 101c, and the other end of the first contact block is fixedly connected to the first connecting rod.

[0035] Even further, a first spring 101e is also provided in the first connection port 101b. The first connecting rod passes through the first spring 101e. One end of the first connecting rod away from the first contact block extends out of the first connection port 101b and is connected to a first connecting pipe 101f. A gas is provided in the first connecting pipe 101f.

[0036] It should be noted that the length of the first connecting pipe 101f in this embodiment can be changed according to the usage scenario. By connecting the first connecting pipe 101f to the first floor 201, the workload of on-site wiring can be reduced. The purpose of filling the gas in the first connecting pipe 101f is to squeeze the gas in the first connecting pipe 101f according to the moving distance of the first piston 101d, so that the gas in the first connecting pipe 101f drives the inner connecting rod 304 to move synchronously along the moving groove 301 for a certain distance. When the inner connecting rod 304 moves, it drives the second floor 202 to move simultaneously, thereby changing the cross-sectional area of the ventilation channel between the first floor 201 and the second floor 202, so as to change the flow rate of the ventilation channel, and thus achieve the purpose of automatically adjusting the indoor temperature.

[0037] Embodiment 2, refer to Figures 1 to 3 , the difference between this embodiment and the first embodiment is that the adjusting mechanism 300 includes a moving groove 301 provided at the end of the first floor 201. One end of the moving groove 301 is provided with a T-shaped pipe 302. The horizontal part of the T-shaped pipe 302 is hollow and inclined, and the vertical part of the T-shaped pipe 302 is solid. One end of the first connecting pipe 101f away from the first connection port 101b is fixedly connected to the lower port of the horizontal part of the T-shaped pipe 302.

[0038] Specifically, the adjusting mechanism 300 further includes a push rod 303 disposed at the end of the second floor 202. An inner connecting rod 304 is fixedly connected to the end of the push rod 303. The outer diameter of the inner connecting rod 304 is the same as the inner diameter of the horizontal portion of the T-shaped tube 302 and has the same inclination angle. The push rod 303 passes through the moving slot 301, and the inner connecting rod 304 is inserted into the horizontal portion of the T-shaped tube 302.

[0039] It should be noted that by changing the volume of the sealed container 100, the diameter of the first connection port 101b, and the moving ratio of the inner connecting rod 304, the moving distance of the ventilation floor 200 per unit temperature change can be adjusted.

[0040] The remaining structures are the same as those in Embodiment 1.

[0041] Working principle: The present invention uses two overlapping moving floors to change the ventilation area, and automatically drives the two moving floors of the ventilation floor 200 to move through the thermal expansion of the liquid to adjust the ventilation volume. Since the first container 101 is filled with water or other types of liquid, the side end of the first cavity 101a extends out of the first connection port 101b. The first connection port 101b is cylindrical. The liquid and the outside are separated by a high-elastic polymer film 101c such as rubber in the small cylindrical body. When the volume of the liquid in the container expands and changes, the film can move outward or inward under the action of the internal and external pressures. The end of the first contact block is close to the film. When the film deforms outward, the first connecting rod extends. When the film deforms inward, the first connecting rod retracts inward under the action of the first spring 101e. By connecting the first connecting rod to the first connecting pipe 101f, when the first connecting rod follows the piston to move, the inner connecting rod 304 can be pushed through the first connecting pipe 101f to drive the second floor 202 to move left and right.

[0042] Embodiment 3, refer to Figures 1 to 3 This embodiment is different from the above embodiments in that the sealed container 100 further includes a second container 102. The structure of the second container 102 is the same as that of the first container 101. The second container 102 is disposed below the first floor 201. It should be noted that the second container 102 is disposed below the first floor 201 and is in direct contact with the cold air of the air conditioner. When the temperature of the cold air of the air conditioner changes, the volume of the liquid in the second container 102 also changes, thereby adjusting the opening degree of the lower ventilation floor 200 and realizing the balanced distribution of the cold air volume at different positions in the computer room.

[0043] The remaining structures are the same as those in Embodiment 2.

[0044] Working principle: The adjusting device of the upper ventilation floor 200 is located above the ventilation floor 200, i.e., in the room. When the temperature in the room changes, the density and volume of the liquid change, causing the piston connected to it to move left and right. The piston pushes the gas in the first connecting pipe 101f to move, thereby pushing the ventilation floor 200 to move through the internal connecting rod 304.

[0045] When the room temperature rises, the volume of the liquid increases and the piston extends. At this time, the internal connecting rod 304 pushes the second floor 202 to move to the right; similarly, when the room temperature drops, the volume of the liquid decreases and the piston retracts. At this time, the internal connecting rod 304 pushes the second floor 202 to move to the left. By reasonably arranging the relative positions of the two ventilation floors 200, when the room temperature rises, the opening of the ventilation floor 200 increases and the cold air flow rate increases, thereby reducing the temperature in the room. When the room temperature drops, the opening of the ventilation floor 200 decreases and the cold air flow rate decreases, thereby increasing the temperature in the room.

[0046] The adjusting mechanism 300 of the lower ventilation floor 200 is below the ventilation floor 200. The cold air from the air conditioner passes through the lower part of the ventilation floor 200 and enters the machine room through the adjustable ventilation floor 200. Similarly, when the temperature of the cold air from the air conditioner changes, the lower ventilation floor 200 will move. When the temperature of the lower cold air rises, the lower ventilation floor 200 moves to the left and the opening of the ventilation floor 200 increases, and the flow rate increases. When the temperature of the lower cold air drops, the opening of the ventilation floor 200 decreases and the flow rate decreases. The purpose of this is to more evenly distribute the cold air obtained at different positions in the machine room. Because the temperature of the cold air from the air conditioner under the ventilation floor 200 in the machine room is not uniform. The cold air temperature is lower in the place closer to the air conditioner and relatively higher in the place farther from the air conditioner. Therefore, it is impossible to achieve balanced control of the temperature field in the machine room, and there will be local overheating and overall coldness. In order to ensure that certain cabinets with larger heat generation are within the specified temperature range, the machine room operation and maintenance personnel often set the target temperature of the machine room relatively low and increase the overall air volume of the air conditioner. By further adjusting the cold air volume in different parts of the machine room according to the cold air temperature through the lower ventilation floor 200, it helps to achieve balanced control of the temperature field in the machine room.
