Description

Technical Field

[0001] The utility model belongs to the technical field of clean air-proof equipment, and in particular relates to a transfer window. Background Art

[0002] The transfer window is one of the auxiliary equipment of the clean room. Its purpose is to effectively reduce the number of times the staff enters the clean room to transport items, prevent external air from polluting the clean room, and is conducive to maintaining positive pressure. It is the best transfer device for the clean room. This equipment is widely used in micro-technology, biological laboratories, pharmaceutical factories, hospitals, food processing industries, LCDs, electronics factories and all other places that require air purification. Its working principle: There is usually an electronic or mechanical interlocking device inside the transfer window to ensure that the doors on both sides cannot be open at the same time to prevent pollutants from non-clean areas from entering the clean area (clean room). Some advanced transfer windows are also equipped with ultraviolet sterilization lamps or other disinfection equipment for regular or automatic disinfection of the inside of the transfer window to ensure the cleanliness of the inside of the transfer window. For example, CN218075775U discloses a UV light sterilization transfer window, please refer to Figure 1 , which includes: a box body, which includes an upper top surface, a lower bottom surface, and a first side surface and a second side surface arranged between the upper top surface and the lower bottom surface; a first ultraviolet lamp, which is arranged on the first side surface; a second ultraviolet lamp, which is arranged on the second side surface; and, an ultraviolet light-sensitive component, including a mounting frame installed on the upper top surface, and a first light-sensitive element and a second light-sensitive element arranged on the mounting frame, wherein the first light-sensitive element is arranged toward the first ultraviolet lamp for detecting the irradiation intensity of the first ultraviolet lamp, and the second light-sensitive element is arranged toward the second ultraviolet lamp for detecting the irradiation intensity of the second ultraviolet lamp. The irradiation intensity of ultraviolet lamps at different positions is detected respectively to determine the remaining service life of ultraviolet lamps at different positions, and ultraviolet lamps with substandard sterilization effects are replaced in time, thereby effectively reducing the pollution to the clean room (clean room).

[0003] Through the analysis of the existing technology, the disadvantages of using ultraviolet sterilization lamps in transfer windows are as follows.

[0004] 1. Insufficient radiation dose may lead to resurrection. During the UV disinfection process, if the radiation dose is insufficient, some inactivated microorganisms may be revived. Therefore, it is necessary to ensure that the required radiation dose is reached to achieve an effective disinfection effect.

[0005] 2. The light decay is large and the life is not long. After hundreds of hours of burning, the ultraviolet light intensity of the ultraviolet germicidal lamp produced by general manufacturers decays quickly, up to 30%, which greatly weakens the sterilization effect. In addition, the cathode damage caused by processing also affects the life of the ultraviolet germicidal lamp.

[0006] 3. It is difficult to remove the dust suspended in the transfer window cavity and adhering to the surface of the transfer object. Utility Model Content

The terms used in the specification herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] Please refer to Figures 2 to 5 On the one hand, the utility model provides a transfer window 122, which includes a box body 100, an air intake mechanism 109, an exhaust mechanism 112, an air pressure detector 120 and a controller 118. A accommodating chamber 101 is arranged in the box body 100, and a first sealing door 102 and a second sealing door 103 are hinged on the front and rear sides of the box body 100 respectively. The first sealing door 102 is used to place the transfer object into the accommodating chamber 101, and the second sealing door 103 takes the transfer object out of the accommodating chamber 101. The controller 118 is respectively connected to the air intake mechanism 109, the exhaust mechanism 112 and the air pressure detector 120 by signal. The air pressure detector 120 is arranged in the accommodating chamber 101, and the air intake mechanism 109 and the exhaust mechanism 112 are respectively connected to the accommodating chamber 101. The air intake mechanism 109 is used to provide purified gas to the accommodating chamber 101, and the exhaust mechanism 112 is used to discharge the gas in the accommodating chamber 101.

[0027] The utility model can remove dust and germs suspended in the receiving chamber 101 and adhering to the surface of the transfer object through the air intake mechanism 109 and the exhaust mechanism 112. If the transfer window 122 is equipped with an ultraviolet lamp, the use of the ultraviolet lamp can be reduced, and the life span can be extended. At the same time, if the radiation dose is insufficient to a certain extent, some inactivated microorganisms may be revived. The air pressure detector 120 and the controller 118 cooperate to conveniently manage the air intake and exhaust, optimize the purification effect in the receiving chamber 101, and avoid the negative pressure in the receiving chamber 101 that makes it difficult to open the sealed door.

[0028] Please refer to Figures 2 to 4 In a preferred embodiment, the ends of the first sealing door 102 and the second sealing door 103 away from the hinge are connected to the box body 100 through the lock body assembly 104. The two are switched between a closed state and an open state through the lock body assembly 104. When the two are in the closed state, they are used to seal the accommodating chamber 101. When the first sealing door 102 is opened, the transfer object is placed in the accommodating chamber 101. When the second sealing door 103 is opened, the transfer object is taken out of the accommodating chamber 101.

[0029] When the first sealing door 102 and the second sealing door 103 are in a sealed state, the accommodating chamber 101 can be purified by air intake and exhaust, and can also be sterilized by ultraviolet light.

[0030] Please refer to Figure 4In a preferred embodiment, the lock body assembly 104 includes a lock tongue 105, a rotary lock handle 106, a lock handle seat 107 and a lock block 108. The lock blocks 108 are respectively arranged on the front and rear sides of the box body 100, and the lock handle seat 107 is respectively arranged on one side of the first sealing door 102 and the second sealing door 103 close to the lock block 108. The rotary lock handle 106 is respectively hinged on the lock handle seat 107, and the rotary lock handle 106 is drivingly connected to the lock block 108 to drive the lock tongue 105 to rotate and lock or open the lock tongue 105 and the lock block 108 to each other.

[0031] Please refer to Figures 2 to 4 The box 100 is provided with two sets of lock body assemblies 104, which are used to close and open the first sealed door 102 and the second sealed door 103 respectively. The lock block 108 is located on one side of the box 100 and a lock groove is formed for the lock block 108 to move. The lock groove can be formed by the end of the lock block 108 close to the lock tongue 105 and the side wall of the box 100. When the lock tongue 105 rotates, it can be placed in the lock groove or away from the lock groove. Further, the thickness of the lock tongue 105 gradually becomes thinner along the placement direction (i.e. Figure 4 The locking tongue 105 is gradually thinned from bottom to top in order to facilitate the insertion of the locking tongue 105 into the locking groove and further tightening.

[0032] Please refer to Figures 2 to 5 In a preferred embodiment, transfer ports are respectively opened on the front and rear sides of the box body 100, and the two transfer ports are respectively connected to the accommodating chamber 101. The first sealing door 102 and the second sealing door 103 both cooperate with the transfer ports, and both are kept sealed and connected with the transfer ports through sealing rings.

[0033] The transfer port (not shown) is connected to the accommodating chamber 101 to form a transfer channel for transferring the object to be transferred. The sealing ring is elastic, and the sealing ring and the clamping structure of the above-mentioned lock body assembly 104 cooperate with each other to further ensure the sealed connection, facilitate the opening and closing of the lock body assembly 104, and simplify the structure.

[0034] Please refer to Figure 5 In a preferred embodiment, the top and bottom of the accommodating cavity 101 are respectively provided with an air intake cavity 111 and an exhaust cavity 113 connected thereto, and both the air intake mechanism 109 and the exhaust mechanism 112 are arranged on the top of the box body 100, and both are connected to the air intake cavity 111 and the exhaust cavity 113, respectively.

[0035] The air intake mechanism 109 and the exhaust mechanism 112 are arranged at the top to facilitate the installation of the box body 100. The air intake cavity 111 and the exhaust cavity 113 are respectively arranged at the top and the bottom of the accommodating cavity 101, and the two are connected with the accommodating cavity 101. The purified gas enters the air intake cavity 111 and is then discharged into the accommodating cavity 101. The gas in the accommodating cavity 101 enters the exhaust cavity 113 and is then discharged through the exhaust mechanism 112. On the one hand, convection can be better formed to discharge the original relatively turbid gas.

[0036] Please refer to Figure 5 In a preferred embodiment, a support grille 115 is provided at the bottom of the accommodating cavity 101 , and the bottom wall of the support grille 115 and the inner bottom wall of the box body 100 are spaced apart to form an exhaust cavity 113 , and a filter element 116 is also provided in the exhaust cavity 113 .

[0037] The filter element 116 may be a filter sponge, and the filter element 116 may filter the gas discharged through the support grille 115, and the support grille 115 may support the object to be transferred, and the holes thereon may discharge the gas containing dust and germs, and at the same time, it may reduce the cleaning times of the accommodating chamber 101 to a certain extent. Furthermore, an air intake baffle 110 is arranged on the top of the accommodating chamber 101, and the air intake baffle 110 is spaced apart from the inner top wall of the box body 100 to form an air intake chamber 111.

[0038] Please refer to Figure 5 In a preferred embodiment, the exhaust end of the air intake mechanism 109 is arranged at the top of the box body 100 , and the air intake end of the air intake mechanism 109 is connected to the exhaust pipe 114 , and the air intake end of the exhaust pipe 114 is connected to the exhaust cavity 113 .

[0039] The outlet end of the exhaust pipe 114 is connected to the inlet end of the air intake mechanism 109, and the outlet end of the exhaust pipe 114 is located in the air intake cavity 111. The middle part of the exhaust pipe 114 is connected to the exhaust cavity 113 after bypassing the right side wall of the box body 100 from the air intake cavity 111. Further, the air intake mechanism 109 and the exhaust mechanism 112 both include an air valve, an air pump and an air pipe, and the air valve, the air pump and the air pipe cooperate with each other to input the gas into the accommodating cavity 101 and discharge the gas in the accommodating cavity 101. Of course, in some embodiments, the air valve and air pipe of the air intake mechanism 109 and the exhaust mechanism 112 are arranged on the box body 100, and the air pump (not shown) and the purified gas storage device (not shown) are externally arranged on the box body 100. For example, the air intake mechanism 109 is an air intake valve, and the air intake pump and the purified gas storage device are connected to the air intake valve through a pipeline. The purified gas storage can be pure carbon dioxide or nitrogen.

[0040] In a preferred embodiment, the transfer window 122 further includes an ultraviolet lamp, which is disposed on the inner wall of the box body 100 and is used to irradiate the accommodating cavity 101 .

[0041] The ultraviolet lamp (not shown) is used to kill the germs inside the accommodating cavity 101. By cooperating with the gas purification system, it can avoid the resurrection phenomenon that may be caused by insufficient radiation dose to a certain extent, and at the same time extend the service life.

[0042] In a preferred embodiment, the first sealed door 102 and the second sealed door 103 are further provided with tempered glass windows, and a power connector 117 is further provided on the top of the box 100 . The power connector 117 is used to electrically connect to the electronic components on the box 100 .

[0043] The tempered glass window (not shown) is used to observe the internal situation of the accommodating cavity 101, which is convenient for the operator to operate and observe.

[0044] Please refer to Figures 2 to 5 When the transfer window 122 is in use, the first sealing door 102 is opened through the previous lock body assembly 104, the object to be transferred is placed in the accommodating chamber 101, the first sealing door 102 is closed and locked, and the accommodating chamber 101 can be purified while ensuring that the first sealing door is locked tightly. There are two ways to purify the accommodating chamber 101. The first is that the air intake mechanism 109 and the exhaust mechanism 112 simultaneously intake and exhaust air, so that the turbid gas with dust and germs originally in the accommodating chamber 101 is gradually discharged, and then the pure gas without dust and germs is completely filled in the accommodating chamber 101; the second is that the air intake mechanism 109 and the exhaust mechanism 112 intermittently intake and exhaust air, such as the exhaust mechanism 112 first discharges a part of the gas in the accommodating chamber 101, and stops exhausting when the air pressure drops to a certain value, and then the air intake mechanism 109 inputs purified gas into the accommodating chamber 101, and stops inputting gas by the air intake mechanism 109 when the air pressure rises to a certain value, and then the exhaust mechanism 112 is exhausted again, and the turbid gas can be gradually discharged by repeating this cycle for many times. After the purification operation of the accommodating chamber 101 is completed, the ultraviolet lamp can be further turned on to eliminate bacteria; after the elimination of bacteria is completed, the ultraviolet lamp is turned off. Before opening the second sealed door 103, the air pressure in the accommodating chamber 101 can be detected by the air pressure detector 120. If it is in a negative pressure, that is, the air pressure in the accommodating chamber 101 is much lower than the air pressure in the clean room, some purified gas can be added to the accommodating chamber 101 to ensure that the air pressure in the accommodating chamber 101 is close to the air pressure in the clean room, thereby avoiding the situation where the second sealed door 103 cannot be opened.
