[0031] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0033] like Figure 1-Figure 6 As shown, the utility model provides a high-sealing biological clean safety cabinet, including a clean cabinet 1 and a glove 6, a transparent cover 2 is hinged on the surface of the clean cabinet 1, an exhaust pipe 3 is fixedly connected to the side wall of the clean cabinet 1, a fan 4 is fixedly connected to the inner wall of the exhaust pipe 3, a filter tube 5 is fixedly connected to the lower surface of the clean cabinet 1, an ultraviolet lamp tube 9 is fixedly connected to the inner wall of the clean cabinet 1, a blocking structure 7 is provided on the surface of the exhaust pipe 3, and an adjustment structure 8 is provided on the surface of the clean cabinet 1.

[0034] The specific configuration and function of the blocking structure 7 and the regulating structure 8 will be described in detail below.

[0035] like Figure 3 and Figure 4As shown, the blocking structure 7 includes a fixed tube 71, which is fixedly connected to the exhaust pipe 3, a slide plate 72 is slidably connected to the inner wall of the fixed tube 71, a ventilation frame 73 is fixedly connected to the surface of the slide plate 72, and the ventilation frame 73 is slidably connected to the inner wall of the exhaust pipe 3, a leaf spring 74 is fixedly connected to the surface of the fixed tube 71, one end of the leaf spring 74 is fixedly connected to the slide plate 72, when the leaf spring 74 is stretched, the slide plate 72 will drive the ventilation frame 73 to slide into the exhaust pipe 3 with the help of the tension of the leaf spring 74, and the leaf spring 74 can achieve the effect of automatically resetting the slide plate 72, a stopper 75 is fixedly connected to the surface of the slide plate 72, and a buffer sleeve 76 is fixedly connected to the arc surface of the stopper 75. The block 75 will drive the buffer sleeve 76 to slide as the slide plate 72 slides. The buffer sleeve 76 can reduce the collision force between the block 75 and the fixed tube 71. The block 75 can prevent the leaf spring 74 from hitting the fixed tube 71 and causing deformation and damage. The outer wall of the air permeable frame 73 is fixedly connected with a circular ring 77. The surface of the circular ring 77 is fixedly connected with a sealing ring 78. The cross-section of the sealing ring 78 is triangular. The sealing ring 78 is slidably connected to the exhaust pipe 3. The sliding of the air permeable frame 73 will drive the sliding of the circular ring 77. The sliding of the circular ring 77 will cause the sealing ring 78 to abut against one end of the exhaust pipe 3. The sealing ring 78 improves the sealing effect of the air permeable frame 73 on the ventilation pipe.

[0036] like Figure 5 and Figure 6 As shown, the adjustment structure 8 includes a clearance hole 81, which is opened on the surface of the clean cabinet 1. The inner wall of the clearance hole 81 is slidably connected with a square frame 82, and the square frame 82 is fixedly connected to the glove 6. The surface of the square frame 82 is fixedly connected with two extension plates 83, and the extension plate 83 is slidably connected to the clean cabinet 1. The surface of the square frame 82 is fixedly connected with an L-shaped plate 84, and the L-shaped plate 84 is internally threaded with a bolt 85. One end of the bolt 85 is rotatably connected with a pressure plate 86. When the bolt 85 is rotated, the bolt 85 will move with the help of the thread and drive the pressure plate 86 to move. The pressure plate 86 reaches the function of limiting the position of the bolt 85, thereby limiting the position of the square frame 82. The surface of the pressure plate 86 is fixedly connected with an anti-skid pad 87, and the anti-skid pad 87 increases the friction between the pressure plate 86 and the clean cabinet 1.

[0037] The overall working principle is that when the clean cabinet 1 is used, the fan 4 and the ultraviolet lamp 9 are turned on, and the ultraviolet lamp 9 can kill the bacteria in the clean cabinet 1. At this time, the air will flow into the clean cabinet 1 through the filter tube 5, and the air in the clean cabinet 1 will be drawn into the exhaust pipe 3. At this time, the flowing air will impact the air frame 73, and the air frame 73 will slide out from the inner wall of the exhaust pipe 3. Then the air can be discharged through the air frame 73. The sliding of the air frame 73 will drive the sliding plate 72 to slide, and the sliding of the sliding plate 72 will compress the leaf spring 74. At the same time, the stopper 75 will follow the sliding of the sliding plate 72 to drive the buffer sleeve 76 to slide, and the buffer sleeve 76 can reduce the stopper 75 and the fixed pipe 71 The collision force between them, the block 75 can prevent the leaf spring 74 from hitting the fixed pipe 71 and causing deformation and damage. When the clean cabinet 1 is not in use, after the fan 4 is turned off, the leaf spring 74 begins to stretch, and the slide plate 72 will use the tension of the leaf spring 74 to drive the air frame 73 to slide into the exhaust pipe 3. The air frame 73 can block the exhaust pipe 3, thereby improving the sealing performance of the clean cabinet 1 and preventing pollutants such as dust or bacteria from entering the clean cabinet 1. The sliding of the air frame 73 will drive the sliding of the ring 77. The sliding of the ring 77 will cause the sealing ring 78 to rest against one end of the exhaust pipe 3. The sealing ring 78 improves the sealing effect of the air frame 73 on the ventilation pipe.

[0038] When the distance between the two gloves 6 needs to be adjusted during operation using the gloves 6, the square frame 82 is slid along the inner wall of the clearance hole 81. The sliding of the square frame 82 will drive the extension plate 83 to slide. The extension plate 83 can block the gap between the clearance hole 81 and the square frame 82. The sliding of the square frame 82 will drive the glove 6 to move. After the glove 6 is adjusted to a suitable position, the bolt 85 is turned. The bolt 85 will move with the help of the thread and drive the pressure plate 86 to move. The movement of the pressure plate 86 will cause the anti-slip pad 87 to rest against the surface of the clean cabinet 1. The anti-slip pad 87 increases the friction between the pressure plate 86 and the clean cabinet 1. The pressure plate 86 limits the position of the bolt 85, thereby limiting the position of the square frame 82. By adjusting the distance between the two gloves 6, it is convenient for workers of different body shapes to use the gloves 6 for operation, thereby improving the practicality of the clean cabinet 1.

[0039] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
