Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleanroom equipment technology, specifically a transfer window with multi-angle dust removal function. Background Technology
[0002] Pass-through windows, as key auxiliary equipment in cleanrooms, play an irreplaceable role in fields with stringent air cleanliness requirements, such as microelectronics, biomedicine, and food processing. Their core function is to safely transfer small items between clean and non-clean areas or areas of different cleanliness levels through physical isolation and air purification technology, while minimizing the risk of cross-contamination. Pass-through windows generally employ a double-door interlocking design, using mechanical or electronic interlocking devices to ensure that both doors cannot be opened simultaneously, forming a unidirectional airflow barrier. Air shower-type pass-through windows use top nozzles to spray high-speed clean airflow during item transfer, effectively removing particles adhering to object surfaces, and work in conjunction with high-efficiency filters to achieve air circulation and purification. Self-cleaning pass-through windows have built-in low-noise centrifugal fans and high-efficiency filtration systems, maintaining an internal clean environment through continuous air supply.
[0003] However, most existing pass-through windows only clean the items inside the window through airflow. Airflow is not effective at cleaning bacteria and strongly adhering dust and dirt on the surface of the items, resulting in poor cleaning effect and easy contamination of the clean area. Utility Model Content
[0004] The purpose of this invention is to solve the problem that existing pass-through windows have poor cleaning effects and are prone to contaminating clean areas.

A pair of doors are symmetrically arranged on both sides of the main body, and a transfer chamber is disposed between the doors. A connecting pipe is vertically arranged at the top center of the transfer chamber. An inlet pipe is rotatably connected to the bottom of the connecting pipe. A diverter pipe is connected to the bottom of the inlet pipe. Several nozzles are symmetrically arranged on both sides of the bottom of the diverter pipe. A driven gear is fixedly connected to the middle of the outer wall of the inlet pipe. A motor is vertically fixedly connected to the top of the main body. A connecting shaft is fixedly connected to the rotating shaft of the motor. The bottom end of the connecting shaft extends into the interior of the transfer chamber. A drive gear is fixedly connected to the bottom end of the connecting shaft. The drive gear meshes with the driven gear. Several air inlets are opened at the top of the transfer chamber, and spherical nozzles are rotatably connected inside the air inlets.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-4 The transfer window with multi-angle dust removal function in this embodiment includes a main body 1. A pair of doors 2 are symmetrically arranged on both sides of the main body 1. A transfer chamber 9 is arranged between the pair of doors 2. A connecting pipe 13 is vertically arranged at the top center of the transfer chamber 9. An inlet pipe 6 is rotatably connected to the bottom of the connecting pipe 13. A diversion pipe 7 is connected to the bottom of the inlet pipe 6. Several nozzles 8 are symmetrically arranged on both sides of the bottom of the diversion pipe 7. A driven gear 12 is fixedly connected to the middle of the outer wall of the inlet pipe 6. A motor 16 is vertically fixedly connected to the top of the main body 1. A connecting shaft 15 is fixedly connected to the rotating shaft of the motor 16. The bottom end of the connecting shaft 15 extends into the interior of the transfer chamber 9. A drive gear 14 is fixedly connected to the bottom end of the connecting shaft 15. The drive gear 14 meshes with the driven gear 12. Several air inlets 10 are opened on the top of the transfer chamber 9. A spherical nozzle 11 is rotatably connected inside the air inlets 10. When transferring items, the transfer window first opens the door 2 facing the non-clean area, places the item inside the transfer chamber 9, and then closes the door 2. At this time, cleaning fluid is pumped into the connecting pipe 13 by the liquid pump. The cleaning fluid flows into the inlet pipe 6 along the connecting pipe 13 and then into the diversion pipe 7. Finally, it is sprayed out along the nozzle 8 at the bottom of the diversion pipe 7 to disinfect and clean the transferred items. At this time, the motor 16 drives the connecting shaft 15 to rotate, causing the drive gear 14 to start rotating. When the drive gear 14 rotates, it drives the driven gear 12 to rotate, causing the inlet pipe 6 to start rotating. When the inlet pipe 6 rotates, it drives the diversion pipe 7 and the nozzle 8 at the bottom to rotate as well, achieving all-round cleaning of the transferred items and effectively improving the cleaning effect. After the items are sprayed and cleaned, the items are air-sprayed through the spherical nozzle 11 inside the air inlet 10 to remove the residual cleaning fluid and dust on the surface of the items, thereby achieving multi-level cleaning of the items and further improving the cleaning effect.
[0022] The diversion pipe 7 is set perpendicularly to the inlet pipe 6, and the bottom of the nozzle 8 is set at an angle toward the middle of the diversion pipe 7.
[0023] The driven gear 12 and the drive gear 14 are provided with protective covers 5, and the top of the protective covers 5 is fixedly connected to the top of the transmission chamber 9. By providing protective covers 5, the driven gear 12 and the drive gear 14 can be protected, thereby improving their service life.
[0024] The bottom of the transfer chamber 9 is provided with several negative pressure holes 17; a vacuum generator is installed at the bottom of the negative pressure holes 17. During air showering, the vacuum generator generates negative pressure on the negative pressure holes 17, thereby absorbing the dust floating inside the transfer chamber 9 and realizing the circulation cleaning of the inside of the transfer chamber 9.
[0025] The edge of the storage door 2 is connected to the side wall of the main body 1 by a hinge 3, and an observation window 18 is provided on the surface of the storage door 2. The observation window 18 can be made of glass, which facilitates the observation of the state of the items.
[0026] An electromagnetic lock 4 is installed between the edge of the compartment door 2 away from the hinge 3 and the main body 1, and the pair of electromagnetic locks 4 are electrically connected. After cleaning, the compartment door 2 facing the clean area is opened to take out the cleaned items; the electromagnetic locks 4 connected by electricity can prevent both compartment doors 2 from opening at the same time.
[0027] Working principle: When transferring items, the transfer window first opens the door 2 facing the non-clean area, places the item inside the transfer chamber 9, and then closes the door 2. At this time, cleaning solution is pumped into the connecting pipe 13 by the liquid pump. The cleaning solution flows along the connecting pipe 13 into the inlet pipe 6 and then into the diversion pipe 7, finally being sprayed out along the nozzle 8 at the bottom of the diversion pipe 7 to disinfect and clean the transferred items. At this time, the motor 16 drives the connecting shaft 15 to rotate, causing the drive gear 14 to start rotating. When the drive gear 14 rotates, it drives the driven gear 12 that meshes with it to rotate, causing the inlet pipe 6 to start rotating. When the inlet pipe 6 rotates, it drives the bottom diversion pipe 7 and nozzle 8 to rotate as well, achieving all-round cleaning of the transferred items and effectively improving the cleaning effect. After the items are cleaned by spraying, the items are air-sprayed through the spherical nozzle 11 inside the air inlet 10 to remove the residual cleaning liquid and dust on the surface of the items, thereby achieving multi-level cleaning of the items and further improving the cleaning effect. After cleaning, the compartment door 2 facing the clean area is opened to take out the cleaned items. The compartment doors 2 on both sides are prevented from opening at the same time by the electromagnetic locks 4 that are electrically connected.
[0028] Although embodiments of the present invention have been shown and described, 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 present invention, the scope of which is defined by the appended claims and their equivalents.
