Embodiment Construction
[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0032] The present invention aims at the problem of cold leakage in the equipment for keeping the internal and external pressure balance of the current freezer, especially the ultra-low temperature medical freezer, which leads to the problem of poor refrigeration effect, and provides a device for maintaining the pressure balance inside and outside the freezer, which can adjust the pressure inside and outside the freezer in real time. And it seals well. Specifically, a device for maintaining pressure balance inside and outside the refrigerator includes a vent pipe and a one-way valve, and one end of the vent pipe is connected to the one-way valve.
[0033] refer to figure 1 and figure 2 As shown, a device for maintaining pressure balance inside and outside the refrigerator includes a vent pipe 1 and a one-way valve 2, and one end of...
