The present invention provides an exposure apparatus (100) that exposes a substrate (W), comprising: an optical system (1, 3) configured to emit light for exposing the substrate (W); a first supplier (7) configured to supply a gas into a chamber (6) where the optical system (1, 3) is arranged; and a second supplier (8) configured to supply a gas to an optical path space where the light from the optical system (1, 3) passes through, characterized in that the second supplier (8) includes a gas blower (10) including a blowing port (11) from which a gas is blown out, and the guide member (20) configured to guide the gas blown out from the blowing port (11) to the optical path space, and the guide member (20) includes a plate member (21).

This utility model relates to the field of smart lock technology and discloses an automatic defogging smart lock display screen, including a front lock body. A front handle is movably installed on the front side of the front lock body. A touch screen is fixedly installed on the front lock body above the front handle. A fingerprint recognition module is also fixedly installed on the front lock body between the front handle and the touch screen. The touch screen and the fingerprint recognition module are electrically connected to the main control board inside the front lock body via cables. Sliding grooves are also provided on both sides of the front lock body. A sliding protective cover is provided on the front side of the touch screen to protect it, keeping it in a relatively enclosed environment. Combined with the desiccant in the first and second moisture-absorbing boxes, the humidity inside the protective cover is reduced, thereby reducing the appearance of fog on the touch screen surface and preventing external rainwater from adhering to the touch screen surface.

The invention relates to the technical field of building decoration line drawing, and discloses a line drawing robot for building decoration, which comprises a vehicle body, an ink box is fixedly connected in the vehicle body through a frame body, an infusion tube is fixedly connected to the bottom of the ink box, and a nozzle is fixedly connected to one end, away from the ink box, of the infusion tube. A mounting cavity, an expansion cavity and a spiral cavity are sequentially formed in the nozzle from top to bottom, a spiral groove is formed in the inner wall of the spiral cavity, a guide hole communicated with the outside is formed in the spiral groove in the inner wall of the spiral cavity, the nozzle is sleeved with a collecting box of an annular structure, and a drainage pipe is fixedly connected into the guide hole; the end, away from the guide hole, of the drainage tube penetrates through the top of the collection box and is slidably connected with the collection box. According to the line drawing robot for building decoration, the situation that residual ink drips from a nozzle, and line drawing continuity and overall precision are influenced and disturbed is avoided, and the clearness of line drawing breakpoints and the tidiness of a working face in a building construction site are effectively improved.

The utility model discloses an anti-fogging nuclear power squint window, and relates to the technical field of squint windows, the anti-fogging nuclear power squint window comprises an outer mounting frame, the outer side of the outer mounting frame is fixedly connected with a first mounting rack, the first mounting rack is internally and fixedly provided with first lead glass, the inner part of the outer mounting frame is fixedly connected with a second mounting rack, and the second mounting rack is fixedly connected with a second lead glass. The beneficial effects of the utility model are that the first mounting rack, the second mounting rack, the third sealing gasket, the third mounting rack, the second sealing gasket, the fourth mounting rack, the first sealing gasket and the outer mounting frame are matched with each other, so that the sealing performance of the interior of the outer mounting frame can be ensured; then inert gas is injected into the outer mounting frame through an air inlet pipe and a second one-way valve, so that air in the outer mounting frame is discharged through an air guide pipe and a first one-way valve, and meanwhile, the surfaces of first lead glass, a concave mirror, a convex mirror and second lead glass are coated with polyvinyl butyral coatings to improve hydrophobicity; therefore, the fogging probability is reduced.

The utility model discloses a fluorine-lined centrifugal pump, and relates to the technical field of centrifugal pumps. The device comprises a pump body, a liquid discharging unit used for discharging high-temperature corrosive substances is arranged on one side of the pump body, and an expansion tank in the liquid discharging unit is arranged below the pump body and communicated with the pump body; the cooling piece is arranged on the inner wall of the expansion tank; and the discharging piece is arranged in the expansion tank. According to the device, the liquid discharging unit is arranged, the volume expansion tank can contain high-temperature corrosive liquid remaining on the pump body, the cooling piece can cool the liquid, and the atomization phenomenon generated when the liquid is discharged is reduced. The two electromagnetic valves are arranged, so that accurate control over liquid inlet and outlet is achieved, the problem of atomization sputtering when an existing fluorine-lined centrifugal pump discharges residual liquid is effectively solved, the safety of operators is guaranteed, and the use safety and reliability of equipment are improved.
