A type of lifting air shower pass-through window Technical Field

[0001] This utility model relates to the field of transfer window technology, specifically to a liftable air shower transfer window. Background Technology

[0002] Pass-through windows are an auxiliary device in cleanrooms, mainly used for transferring small items between clean areas and between non-clean areas to reduce the number of times the cleanroom door is opened and minimize contamination in the clean area. They are widely used in places requiring air purification, such as medical, biopharmaceutical, laboratory, electronics manufacturing, and food processing industries.

[0003] Existing air shower pass-through windows can only be used in two adjacent spaces on a single floor, and cannot be used for lifting and transferring items and air shower cleaning in a space of two floors, resulting in limited use. Therefore, a lifting air shower pass-through window is proposed. Summary of the Invention

[0004] To address the problems in the existing technology, this utility model provides a liftable air shower pass-through window to facilitate the transfer of items between people on different floors, thereby improving the convenience of transferring items between people on different floors.

[0005] The technical solution adopted by this utility model to solve its technical problem is a lifting air shower pass-through window, including a cabinet. A filter and a high-pressure fan are provided at the bottom of one end of the cabinet. The exhaust end of the high-pressure fan is connected to the exhaust end of the filter, and the inlet end of the filter is connected to the bottom of the cabinet.

[0006] The cabinet has a first cabinet door at the top and a second cabinet door at the bottom of the outer side, with the first cabinet door located at the top or bottom of one side of the cabinet and the second cabinet door located at the top or bottom of the other side of the cabinet. The cabinet has a stainless steel plate for supporting the lifting of items inside, and the stainless steel plate is provided with air vents.

[0007] By adopting the above technical solution, a transfer window consisting of a cabinet, a first cabinet door, a second cabinet door, and a stainless steel plate in two layers can be used to transfer items between people on different floors, improving the convenience of transferring items between people on different floors.

[0008] Specifically, internal threaded sleeves are fixedly provided at the middle of both ends of the stainless steel plate, and threaded rods are inserted into the internal threads of the internal threaded sleeves. The top and bottom of the threaded rods are rotatably connected to the top and bottom of the cabinet body through bearings, respectively.

[0009] The outer circumference of the rotating shaft of the threaded rod is fixed with a synchronous pulley, and the synchronous pulleys on the threaded rods at both ends of the cabinet are connected by a synchronous belt.

[0010] Specifically, a servo motor is installed at one end of the top of the cabinet, and the drive end of the servo motor is connected to the rotating shaft of the threaded rod at the corresponding position.

[0011] By adopting the above technical solution, through the setting of internal threaded sleeve and threaded rod, after the threaded rod is driven to rotate by the servo motor, the threaded rod rotates synchronously based on the synchronous wheel, so that the stainless steel plate moves up and down on the threaded rod based on the internal threaded sleeve at both ends, so that the stainless steel plate can realize the lifting and transferring of the supported items.

[0012] Specifically, guide sleeves are provided at the corners of the stainless steel plate, and guide rods are inserted into the guide sleeves. The top and bottom of the guide rods are fixedly connected to the top and bottom of the cabinet body, respectively.

[0014] Specifically, the cabinet body has exhaust nozzles at equal intervals at the top, which are connected to the exhaust end of the high-pressure blower, and ultraviolet germicidal lamps are installed at the top of the cabinet body between the exhaust nozzles.

[0015] The ultraviolet germicidal lamp has a normally open switch. The switches are respectively located on both sides of the cabinet and at the closing point of the first and second cabinet doors. When the first and second cabinet doors are closed, the switches are pressed. The switches are connected in series.

[0016] By adopting the above technical solution, the ultraviolet germicidal lamp can continuously irradiate and sterilize the surface of the stainless steel plate used for storing items. After the first or second cabinet door is opened, the corresponding switch button will lose pressure and disconnect the power supply, and the ultraviolet germicidal lamp will stop working.

[0017] The beneficial effects of this utility model are as follows: The transfer window, consisting of a cabinet, a first cabinet door, a second cabinet door, and a stainless steel plate, has a two-tiered structure. With the use of an exhaust nozzle, the surface of items entering the cabinet can be blown to remove dust. This allows for the transfer of items between people on different floors, improving the convenience of transferring items between floors. It solves the problem that existing air shower transfer windows can only be used in two adjacent spaces on a single floor, and cannot be used for lifting and transferring items and air shower cleaning in a space between two floors, resulting in limited applicability.

The exhaust end of the high-pressure fan 3 is connected to the exhaust end of the filter 2, and the inlet end of the filter 2 is connected to the bottom of the cabinet 1.

[0026] The cabinet 1 is provided with a first cabinet door 11 and a second cabinet door 12 at the top and bottom of the outer side, respectively. The first cabinet door 11 is located at the top or bottom of one side of the cabinet 1, and the second cabinet door 12 is located at the top or bottom of the other side of the cabinet 1. The cabinet 1 is provided with a stainless steel plate 13 for supporting the lifting of items. The stainless steel plate 13 is provided with air holes.

[0027] The present invention also includes that the stainless steel plate 13 has internal threaded sleeves 14 fixedly provided at the middle of both ends, and the internal threaded sleeves 14 have internal threaded rods 15 inserted into them. The top and bottom of the threaded rods 15 are rotatably connected to the top and bottom of the cabinet 1 through bearings, respectively.

[0028] The outer periphery of the rotating shaft of the threaded rod 15 is fixed with a synchronous wheel 151, and the synchronous wheels 151 on the threaded rods 15 at both ends inside the cabinet 1 are connected by a synchronous belt.

[0029] The present invention also includes a servo motor 16 installed at one end of the top of the cabinet 1, and the drive end of the servo motor 16 is connected to the rotation shaft of the threaded rod 15 at the corresponding position.

[0030] In use, by utilizing the internal threaded sleeve 14 and the threaded rod 15, after the servo motor 16 drives the threaded rod 15 to rotate, the threaded rod 15 rotates synchronously based on the synchronous wheel 151, so that the stainless steel plate 13 moves up and down on the threaded rod 15 based on the internal threaded sleeves 14 at both ends, so that the stainless steel plate 13 can realize the lifting and lowering of the supported items.

[0031] The present invention also includes a guide sleeve 17 provided at the corner of the stainless steel plate 13, a guide rod 18 inserted in the guide sleeve 17, and the top and bottom of the guide rod 18 being fixedly connected to the top and bottom of the cabinet 1, respectively.

[0032] In use, the guide rod 18 and guide sleeve 17 can guide the movement direction of the stainless steel plate 13, thereby improving the stability of the stainless steel plate 13 during lifting and lowering.

[0033] The present invention also includes that the top of the cabinet 1 is provided with exhaust nozzles 19 connected to the exhaust end of the high pressure blower 3 at equal intervals, and that an ultraviolet germicidal lamp 110 is installed on the top of the cabinet 1 and between the exhaust nozzles 19.

[0034] The switch 111 of the ultraviolet germicidal lamp 110 is a normally open switch. The switches 111 are respectively located on both sides of the cabinet 1 and at the closing position of the first cabinet door 11 and the second cabinet door 12. After the first cabinet door 11 and the second cabinet door 12 are closed, the switch 111 is pressed. The switches 111 are connected in series.

[0035] When in use, the ultraviolet germicidal lamp 110 can continuously irradiate and sterilize the surface of the stainless steel plate 13 where the items are stored.

The specific orientation of the first and second cabinet doors 11 and 12 is determined according to actual usage requirements. Similarly, when adjacent rooms on the same floor require access, the first and second cabinet doors 11 and 12 can be opened on the upper and lower sides of the cabinet 1 respectively for use by people on the same floor. When it is necessary to transfer items between upper and lower floors, the corresponding threaded rod 15 can be driven to rotate by the servo motor 16, causing the threaded rod 15 to rotate synchronously with the synchronous pulley 151. The stainless steel plate 13 rotates stepwise, causing it to move up and down on the threaded rod 15 based on the internal threaded sleeves 14 at both ends. This allows the stainless steel plate 13 to lift and transfer the supported items. During this transfer, the high-pressure blower 3 delivers high-pressure air to the exhaust nozzle 19, and the air blows onto the items on the stainless steel plate 13 through the exhaust nozzle 19 to remove dust. The air generated by the blowing passes through the holes on the stainless steel plate 13 and is discharged downwards. Based on the suction force of the high-pressure blower 3 on the filter 2, the discharged air passes through the filter 2 and enters the high-pressure blower 3 for use, thus completing the air shower operation.
