Description

Technical Field

[0001] This invention belongs to the field of roller shutter door technology, specifically relating to a sealed door with good door frame sealing effect. Background Technology

[0002] A cleanroom is a well-sealed space where parameters such as air cleanliness, temperature, humidity, pressure, and noise are controlled as needed. The development of cleanrooms is closely linked to modern industry and cutting-edge technology. The environmental requirements of precision machinery industries (such as the processing of gyroscopes and miniature bearings) and semiconductor industries (such as the production of large-scale integrated circuits) have spurred the development of cleanroom technology.

[0003] The announcement CN114991652A discloses a type of closed roller shutter purification door and a sealing door with good sealing effect on the door frame. The door curtain and the door frame are tightly fitted by the tension generated by the mechanical structure to complete the seal. However, this sealing process is relatively complicated and lacks an intelligent detection system. If the sealing effect is not up to standard, it is not only impossible to monitor in time, but the mechanical structure also needs to be repaired. The overall operation is relatively cumbersome, so it has great limitations in practical use and has room for improvement. Summary of the Invention

[0004] The purpose of this invention is to provide a sealing door with good door frame sealing effect, so as to solve the problems mentioned in the background art that current sealing doors use too many mechanical structures to achieve sealing, resulting in long maintenance time once a failure occurs, and the sealing effect cannot be monitored in a timely manner.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sealed door with good door frame sealing effect, comprising symmetrically arranged door frames and a top shell installed at the top of the door frames, wherein a door curtain is disposed inside the top shell, and a weighted rod is connected to the bottom end of the door curtain, wherein the weighted rod and the edge area of ​​the door curtain are both inside the door frame, and a sealing mechanism is disposed on the inner side of the door frame, the sealing mechanism comprising:

[0006] An adsorption component is embedded inside the front surface of the door frame. The adsorption component has an exhaust section and an exhaust section. The exhaust section extends to the inside of the door frame, while the exhaust section is connected to an external vacuum assembly. The vacuum assembly exhausts the air inside the door frame and creates negative pressure to adsorb the door curtain onto the inside of the door frame, thereby achieving a seal.

[0007] The detection unit is located on the inner side of the adsorption assembly and is positioned near the door curtain;

[0008] A controller is installed on the outside of the door frame. A wireless receiving module and a wireless transmitting module are respectively installed in the controller and the detection unit. The detection unit is wirelessly connected to the controller.

[0009] As a preferred technical solution of the present invention, the front surface of the door frame is provided with a groove, and the adsorption component is placed in the groove; the adsorption component includes a hollow functional frame, and the front and rear surfaces of the functional frame are provided with multiple holes; the exhaust part is a vacuum suction cup installed at the hole position on the rear surface of the functional frame, and the exhaust part is a vacuum tube connected to the hole position on the front surface of the functional frame.

[0010] As a preferred technical solution of the present invention, the detection unit includes a position sensor disposed on the rear surface of the functional frame. The position sensor detects the distance between the door curtain and the vacuum suction cup. If the distance between the two is too large, it indicates that the sealing effect is poor, and vice versa, it indicates that the sealing effect is good. The height of the position sensor is less than the height of the functional frame.

[0011] As a preferred technical solution of the present invention, a partition strip is also fixed on the inner side of the door frame, which divides the interior of the door frame into two areas to further achieve sealing and connection with the vertical bar. A gap is left between the partition strip and the groove on the front surface of the door frame, and the end of the vertical bar is provided with a groove for the partition strip to slide into.

[0012] As a preferred technical solution of the present invention, the side of the functional frame is provided with a hole, and a spring is provided in the hole. The spring abuts against the inner wall of the groove on the front surface of the door frame, and the functional frame is installed by the spring's rebound force, thus preventing the functional frame from separating from the groove.

[0013] As a preferred technical solution of the present invention, the bottom end face of the vertical bar is provided with a corner groove, and a plurality of blowing heads are installed on the front surface of the corner groove. The rear surface of the blowing head is connected to an air pipe that passes through the vertical bar and is connected to an external air supply device. When the vertical bar is in contact with the ground, the blowing head is used to blow the area outside the door curtain, further reducing the probability of dust entering the clean room.

[0014] As a preferred technical solution of the present invention, a rubber plate is bonded to the bottom end surface of the plumb line, which can improve the stability of the plumb line during placement. The width of the rubber plate is the distance between the inner wall of the corner groove and the inner side of the plumb line.

[0015] As a preferred technical solution of the present invention, a shaft is provided inside the top shell, the curtain is rolled up on the shaft, and a motor is installed inside the drive component. The motor is connected to one end of the shaft for transmission. The motor drives the shaft to rotate, and the rotation of the shaft will complete the rolling up of the curtain.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] In this invention, the door curtain is adsorbed onto the inside of the door frame using vacuum adsorption, ensuring the sealing of the connection. This structure is modular, which facilitates production, processing and installation. Compared with mechanical structures, it is simpler and easier to maintain if problems occur. It can also intelligently detect the sealing effect. Once the sealing is affected, it can be detected quickly to prevent a large amount of dust from entering the clean room.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1 to 4 This invention provides a technical solution: a sealed door with good door frame sealing effect, including symmetrically arranged door frames 100 and a top shell 101 installed at the top of the door frame 100. A door curtain 102 is disposed inside the top shell 101, and a weighted rod 104 is connected to the bottom end of the door curtain 102. The weighted rod 104 and the edge area of ​​the door curtain 102 are both inside the door frame 100. A sealing mechanism is disposed on the inner side of the door frame 100, and the sealing mechanism includes:

[0027] An adsorption component is embedded inside the front surface of the door frame 100. The adsorption component has an exhaust section and an exhaust section. The exhaust section extends to the inside of the door frame 100, while the exhaust section is connected to an external vacuum assembly. The vacuum assembly exhausts the air inside the door frame 100 and adsorbs the door curtain 102 onto the inside of the door frame 100 by generating negative pressure, thereby achieving a seal.

[0028] The detection unit is located on the inner side of the adsorption assembly and is positioned near the door curtain 102;

[0029] A controller 108 is installed on the outside of the door frame 100. A wireless receiving module and a wireless transmitting module are respectively installed in the controller 108 and the detection unit. The detection unit is wirelessly connected to the controller 108. The detection unit detects the tightness between the door curtain 102 and the door frame 100 to detect the sealing performance and reports it to the controller 108.

[0030] In this embodiment, a groove is provided on the front surface of the door frame 100, and the adsorption component is placed in the groove. The adsorption component includes a hollow functional frame 200, and multiple holes are provided on both the front and rear surfaces of the functional frame 200. The exhaust part is a vacuum suction cup 202 installed at the hole position on the rear surface of the functional frame 200, and the exhaust part is a vacuum tube 201 connected to the hole position on the front surface of the functional frame 200. During the sealing of the door curtain 102, the external vacuum assembly generates negative pressure and adsorbs the air inside the door frame 100 through the vacuum tube 201 and the vacuum suction cup 202, so that negative pressure is generated inside the door frame 100. At this time, the door curtain 102 will stick tightly to the vacuum suction cup 202, thereby completing the adsorption of the door curtain 102.

[0031] In this embodiment, the detection unit includes a position sensor 203 disposed on the rear surface of the functional frame 200. The position sensor 203 detects the distance between the door curtain 102 and the vacuum suction cup 202. If the distance between the two is too large, it indicates that the sealing effect is poor, and vice versa, it indicates that the sealing effect is good. The height of the position sensor 203 is less than the height of the functional frame 200.

[0032] In this embodiment, a partition strip 107 is also fixed on the inner side of the door frame 100. The partition strip 107 divides the interior of the door frame 100 into two areas, further achieving sealing and connection with the vertical rod 104. A gap is left between the partition strip 107 and the groove on the front surface of the door frame 100. The end of the vertical rod 104 is provided with a groove for the partition strip 107 to slide into.

[0033] In this embodiment, a hole is provided on the side of the functional frame 200, and a spring 204 is provided in the hole. The spring 204 abuts against the inner wall of the groove on the front surface of the door frame 100. The spring 204 completes the installation of the functional frame 200 by its rebound force, thus preventing the functional frame 200 from separating from the groove.

[0034] In this embodiment, a corner groove 104a is provided on the bottom end face of the vertical bar 104. A plurality of blowing heads 105 are installed on the front surface of the corner groove 104a. An air pipe that passes through the vertical bar 104 is connected to the rear surface of the blowing head 105. The air pipe is connected to an external air supply device. When the vertical bar 104 is in contact with the ground, the blowing head 105 blows the external area of ​​the door curtain 102, further reducing the probability of dust entering the clean room.

[0035] In this embodiment, a rubber plate 106 is bonded to the bottom end surface of the plumb rod 104, which can improve the stability of the plumb rod 104 during placement. The width of the rubber plate 106 is the distance between the inner wall of the corner groove 104a and the inner side surface of the plumb rod 104.

[0036] In this embodiment, a shaft is provided inside the top shell 101, and the curtain 102 is wound around the shaft. A motor is installed inside the drive component 103. The motor is connected to one end of the shaft. The motor drives the shaft to rotate, and the rotation of the shaft will complete the winding of the curtain 102.

[0037] Although embodiments of the invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
