The utility model discloses a switch power supply circuit with a switching function, which comprises a PD power supply module, a direct current adapter power supply module and a PD chip, and is characterized in that a voltage output end of the PD power supply module is connected to a power supply input pin of the PD chip; after being connected in parallel with a power supply output pin of the PD chip, the power supply is connected to a power supply input of the switch; the voltage output end of the DC adapter power supply module is connected with the voltage detection pin of the PD chip. The PD chip is used for cutting off the connection between the power supply input pin and the power supply output pin when the voltage detection pin detects a high level, so that the DC adapter power supply module supplies power to the switch; and the PD chip is also used for controlling the power input pin and the power output pin to be conducted when the voltage detection pin detects a low level, so that the PD power supply module supplies power to the switch. According to the scheme, the problem that the application scene and the application range of the switch in the related technology are limited can be solved.

The utility model discloses a medical sewage pretreatment device which comprises a treatment box, a box cover covers the top end of the treatment box, a sewage inlet is formed in the box cover, a filter screen is arranged in the treatment box, and a supporting table convenient for placing the filter screen is fixedly arranged on the inner wall of the treatment box in the circumferential direction; the filter screen is obliquely arranged, a sewage draining exit is formed in the treatment box at the lower end of the filter screen, and a collecting tank is fixedly arranged on the outer wall of the treatment box at one side of the sewage draining exit. The box cover is arranged at the top end of the treatment box, and the filter screen placed on the supporting table can be taken out by opening the box cover, so that the filter screen is convenient to clean and replace; by means of the obliquely-arranged filter screen, a part of impurities filtered on the filter screen slide into the drain outlet and are accumulated in the collecting tank, the filter screen can be automatically cleaned, the application environment and the overall performance of the device are greatly improved, and the device is practical, simple, safe, reliable, long in service life and easy to popularize.

The application discloses an atomizing device, which comprises a shell assembly, a first atomizer, a second atomizer and a gating structure. The shell assembly is surrounded to form a mounting cavity and is provided with an air inlet channel communicated with the mounting cavity. The first atomizer, the second atomizer and the gating structure are arranged in the mounting cavity. The first atomizer comprises a first atomizing assembly, and the first atomizing assembly is provided with a first atomizing channel. The second atomizer comprises a second atomizing assembly, and the second atomizing assembly is provided with a second atomizing channel. The gating structure is used for selectively connecting one of the first atomizing channel and the second atomizing channel with the air inlet channel in fluid communication. The atomizing power of the first atomizing assembly is greater than that of the second atomizing assembly. After the first atomizing assembly is connected with the air inlet channel in fluid communication through the gating structure, the second atomizing assembly can generate a second aerosol with a small atomizing amount at a time. The second aerosol is a smokeless aerosol, has very low visibility or is almost invisible, and can avoid affecting others in public places as much as possible.

The flexible photovoltaic support is applied to the field of supports and comprises two bases, the tops of the bases are rotationally connected with a supporting plate, a through groove is formed in the supporting plate, the top of the supporting plate is connected with a first threaded rod in a penetrating and threaded mode, the top end of the first threaded rod is rotationally connected with a U-shaped plate through a bearing, and the U-shaped plate is connected with a second threaded rod in a penetrating and threaded mode. A movable block is rotationally connected to the interior of the U-shaped plate, a second screw rod is connected to one side of the movable block in a penetrating and threaded mode, a connecting base is rotationally connected to one side of the second screw rod through a bearing, and two steel nooses are arranged on one side of the base. The photovoltaic panel bracket has a height adjusting function, is simple and convenient to operate, improves the application environment and flexibility of the bracket, can conveniently stretch and fix the steel noose without assistance of external objects, improves the tightening effect after the steel noose is installed, and enhances the wind resistance and stability of the photovoltaic panel.
