Provided is a liquid collecting device, which comprises a collecting container, wherein the collecting container is provided with a diversion cavity for diverting a body fluid collected; on a wall of the collecting container, at least one jacket cavity configured to store a storage liquid is provided, the jacket cavity is provided around the diversion cavity, and the jacket cavity extends along an axial direction of the diversion cavity, and a cross section of the jacket cavity is annular; and the diversion cavity has an inflow port and an outflow port, and an aperture of the inflow port is larger than that of the outflow port.

Liquid collecting device

The present disclosure provides an electrolyte additive, an electrolyte and a lithium ion secondary battery containing the same. The electrolyte additive has a structure of Formula (1), wherein Ris hydrogen, a phenyl, a cyano group, an alkyl cyano group or a Cto Calkyls, and each of Rto Ris independently selected from hydrogen or a Cto Calkyl. By means of the electrolyte additive, the electrolyte and the lithium ion secondary battery containing the same of the present disclosure, a technical effect of improving electric performance of the lithium ion secondary battery at high voltage and high temperature is achieved. 

Electrolyte additive, electrolyte and lithium ion secondary battery containing the same

A variable capacity compressor is provided, including: two cylinders and a middle plate; at least one flow channel provided in the middle plate, wherein one end of the flow channel is connected to an exhaust chamber of any one of the two cylinders, the other end is connected to a suction chamber of the other one of the two cylinders. In present disclosure, by setting a flow channel in the middle plate of the variable capacity compressor, the exhaust chamber of one cylinder is connected to the suction chamber of the other cylinder. When the flow channel is completely closed, the two cylinders operate independently; when the flow channel is opened, the refrigerant in the exhaust chamber flows into the suction chamber through the flow channel, that is, the upper cylinders and the lower cylinder are connected to each other, which can adjust the capacity of the compressor.

Variable capacity compressor

A dual-cylinder two-stage variable capacity compressor is provided, including: a first cylinder, having an exhaust port connected to a first exhaust channel: a second cylinder, wherein the second cylinder is provided with a ventilating slider, and the ventilating slider is provided with a first gas transit channel and a second gas transit channel; wherein, when the ventilating slider is at a first connecting position, the first exhaust channel is connected to a suction channel in a second cylinder when the ventilating slider is at a second connecting position, the first exhaust channel is connected to a second exhaust channel. The compressor of the present disclosure can vary its own capacity, that is, the variation of the compressor's capacity can be realized by arranging a ventilating slider, which will meet the requirements of variation loads of the compressor in different seasons.
