The invention discloses an integrated water channel cleaning device. The integrated water channel cleaning device comprises a water channel and a main cleaning tank, wherein a cleaning mechanism is arranged in the main cleaning tank. The integrated water channel cleaning device is characterized by also comprising a fruit and vegetable cleaning tank, wherein the water channel, the fruit and vegetable cleaning tank and the main cleaning tank are arranged in parallel and form a whole. By arranging the water channel, the fruit and vegetable cleaning tank and the main cleaning tank in an integrated manner, the water channel cleaning device can meet daily life requirement on separate cleaning according to different meat and vegetables, different sizes and different pollution levels.

A fuel cell system mounted in a vehicle includes a fuel cell stack, a coolant supply mechanism, and a fuel gas supply mechanism. The coolant supply mechanism includes a coolant supply pipe and a coolant discharge pipe, provided on a front side in a traveling direction of the vehicle, relative to the fuel cell stack. The fuel gas supply mechanism includes a fuel gas supply pipe, provided on a rear side in the traveling direction, relative to the fuel cell stack.

First and second fuel cell stacks having a simple and compact structure are connected in parallel to each other to enable ensuring a desired electric power generating performance. The first and second fuel cell stacks have the same structure and are arranged in parallel to each other with polarities thereof reversed. A manifold piping is mounted to one ends of the first and second fuel cell stacks. In order to supply an oxidizer gas, a fuel gas, and a coolant to the first and second fuel cell stacks, at least an oxidizer-gas supply pipe, a fuel-gas supply pipe, and a coolant supply pipe in the manifold piping are provided to be symmetrical with respect to the first and second fuel cell stacks.

Prior to wafer processing, pressure ratio control is executed on a divided flow rate adjustment means so as to adjust the flow rates of divided flows to achieve a target pressure ratio with regard to the pressures in the individual branch passages. As the processing gas from a processing gas supply means is diverted into first and second branch pipings under the pressure ratio control and the pressures in the branch passages then stabilize, the control on the divided flow rate adjustment means is switched to steady pressure control for adjusting the flow rates of the divided flows so as to hold the pressure in the first branch passage at the level achieved in the stable pressure condition. Only after the control is switched to the steady pressure control, an additional gas is delivered into the second branch passage via an additional gas supply means.

A heater unit having a main body constructed in the form of a housing and covers the entire flow path forming sections of the valve and joints, and a heater built in the main body is mounted on the valve. The heater includes a direct heating section and a radiant heating section. The direct heating section heats at least a part of the flow path forming sections of the valve through direct contact heating. The radiant heating section heats the inside of the main body of the heater unit by radiant heat.

A fuel gas inlet, a fuel gas outlet, an oxygen-containing gas inlet, an oxygen-containing gas outlet, and other components, which are disposed at upper and lower portions at both ends in the lateral direction, are provided in a first fuel cell stack. A plurality of cooling medium inlets, a plurality of cooling medium outlets, and other components are provided at lower portions on the long side and at upper portions on the long side respectively. A cooling medium flows from the lower portions to the upper portions through cooling medium flow passages to cool the power generation surface smoothly and reliably.

The invention discloses a self-control urethral catheter. A switch assembly is arranged at a urethral catheterization cavity hole of a main catheter body; the switch assembly comprises a shell, a rotating core and a handle; a cavity allowing a rotating core to be arranged in a matched mode and capable of rotating is formed in the shell, the upper side and the lower side of the cavity run through outwards to form main flow channels allowing urine to pass through; a urination flow channel and a pressure flow channel with different angles are formed in the rotating core, and a pressure film is arranged in the pressure flow channel and used for rupture urination when hydraulic pressure exceeds the bearing capacity of the pressure film; when the rotating core rotates, one of the urination flowchannel and the pressure flow channel selectively conducts the upper main flow channel and the lower main flow channel, and the handle is connected with the rotating core and extends out of an inserting pipe to be driven by people to rotate. The functions of opening and closing an urination pipeline and a safety pressure pipeline originally are achieved through one pipeline, urine control is achieved, the pipeline structure is simplified, simplification of an external pipeline and a fixing structure of a human body after the urethral catheter is arranged is facilitated, the treatment environment is simplified, and troubles brought to doctors or patients in the medical treatment process due to an original complex structure are avoided.
