In the description of the utility model, it should be explained that the orientation or position relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like is the orientation or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and cannot be understood as indicating or implying that the indicated device or element must have a specific orientation, a specific orientation and operation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying the importance of the opposite.

[0020] The utility model will be further described in combination with the drawings.

[0021] As Figs. 1-3As shown, a double-air-tight waste bin structure includes a first air-tight strip 1, a second air-tight strip 2, a waste bin 3, a waste bin lid 4, and a mounting flange 5. The mounting flange 5 is connected to the upper end of the outer wall of the waste bin 3. The second air-tight strip 2 is disposed between the lower end of the inner wall of the mounting flange 5 and the outer wall of the waste bin 3. The upper end of the mounting flange 5 is connected to the waste bin lid 4. The first air-tight strip 1 is disposed between the upper end of the inner wall of the mounting flange 5 and the outer wall of the waste bin lid 4. The waste bin 3 is made of 316L stainless steel.

[0022] like Fig. 2 As shown, the upper and lower ends of the inner wall of the mounting flange 5 are respectively provided with annular square grooves 9, and the first air-sealing strip 1 and the second air-sealing strip 2 are located in the annular square grooves 9. The first air-sealing strip 1 and the second air-sealing strip 2 are made of silicone rubber; the first air-sealing strip 1 and the second air-sealing strip 2 have a hollow structure and can be inflated and deflated. After being inflated, the first air-sealing strip 1 fits tightly against the outer wall of the waste bin lid 4, forming a sealing effect and fixing the waste bin lid 4; after being inflated, the second air-sealing strip 2 forms a sealing effect against the outer wall of the waste bin 3 and fixes the air-sealed bin from left to right. After the air-sealing strips are deflated, they no longer have a sealing effect, making it easy to remove the waste bin lid 4 and the waste bin 3.

[0023] Specifically, three fixing blocks 11 are connected at equal intervals on the upper part of the outer wall of the waste bin 3, and three mounting grooves 12 are opened on the inner wall of the mounting flange 5. The waste bin 3 is connected to the mounting flange 5 by being snapped into the mounting grooves 12 by the fixing blocks 11.

[0024] like Fig. 3 As shown, the waste bin 3 is an open-top barrel-shaped structure, installed within the inner ring of the second airtight strip 2. It is sealed by inflating the second airtight strip 2 and secured by fixing blocks on the bin body to prevent it from falling during operation. The inside of the bin collects waste generated during aseptic production or aseptic inspection. Three fixing blocks 11 are evenly distributed on the upper part of the waste bin 3. These three fixing blocks 11 correspond to three mounting slots 12 on the mounting flange 5. When installing the waste bin, it is inserted into the mounting flange and rotated to align the fixing blocks 11 with the mounting slots 12, ensuring the waste bin remains in a fixed position. The bin body is made of 316L stainless steel by stamping or welding, meeting the relevant legal and regulatory requirements for isolator manufacturing.

[0025] Specifically, the waste bin lid 4 is installed at the opening of the waste bin 3 and is sealed by inflation of the first airtight strip 1. A retaining rim is provided along the upper edge of the waste bin lid 4 for positioning and decoration. During normal use, the first airtight strip 1 is not inflated, and the waste bin lid 4 can be freely inserted and removed.

[0026] Specifically, the mounting flange 5 is connected with the isolator bottom plate through screws, and a flange sealing gasket 6 is arranged between the mounting flange 5 and the isolator bottom plate. The mounting flange 5 plays a role of supporting the whole device.

[0027] Specifically, the outer wall of the mounting flange 5 is provided with a sensor mounting groove 10 at the upper end and the lower end, respectively. The first photoelectric sensor 7 is mounted in the sensor mounting groove 10 at the upper end of the outer wall of the mounting flange 5, and the second photoelectric sensor 8 is mounted in the sensor mounting groove 10 at the lower end of the outer wall of the mounting flange 5. The first photoelectric sensor 7 and the second photoelectric sensor 8 are mounted in the two sensor mounting grooves of the mounting flange and can detect whether the waste barrel 3 and the waste barrel cover 4 are installed in place. When it is detected that the waste barrel 3 or the waste barrel cover 4 is not installed in place, the air-tight sealing strip is not allowed to be inflated through the PLC program control, so as to avoid damaging the air-tight sealing strip. After the photoelectric sensor detects that the waste barrel or the waste barrel cover is installed in place, the air-tight sealing strip is allowed to be inflated. The control circuit of the PLC controller can be realized through simple programming by those skilled in the art, and the power supply also belongs to the common knowledge in the art, and the utility model is mainly used for protecting the mechanical device, so the control mode connection will not be explained in detail. The photoelectric sensor is an existing device, and the model can be KI T-FG series TOF photoelectric sensor.

[0028] The double-air-tight waste barrel structure can meet the requirements that the sealing performance of the isolator cabin body is not affected when the waste barrel is removed, the sterile environment inside the isolator cabin body is not affected, and the sterile production or sterile inspection work can be continued after the waste barrel is removed.

[0029] The above embodiments are only used to illustrate the technical solutions of the utility model, but not limit them. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions recorded in the above embodiments can be modified, or some or all of the technical features can be replaced equivalently. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
