A liquid ejecting device comprising: a liquid ejecting head having a nozzle forming surface on which a liquid ejecting nozzle is provided; a part of a liquid receiving member having an opening larger than the nozzle forming surface and not forming The part of the liquid receiving member of the opening functions as a liquid receiving part that receives the liquid ejected from the liquid ejection nozzle during ejection; the liquid receiving member moving mechanism moves the liquid receiving member so that the opening and the nozzle are formed during printing. The faces are arranged facing each other, and the liquid receiving member is moved so that the liquid receiving part and the nozzle forming face are arranged facing each other during ejection; the liquid ejection head moving mechanism moves the liquid ejecting head so that the nozzle forming face is arranged on the same side as the nozzle forming face during printing. The target conveyance surface is close to the printing position, and the liquid ejection head is moved so that the nozzle formation surface is arranged at the ejection position away from the target conveyance surface during ejection.

An electrical cabinet having a solar power supply and targeted cooling capability. The electrical cabinet comprises a cabinet body (2), a mounting board (28) fixed in the cabinet body (2) and configured for mounting of electrical components (22), the electrical components (22) mounted on the mounting board (28) and to be cooled, and a targeted cooling device configured to perform cooling on the electrical components (22) to be cooled. The targeted cooling device comprises a fixed carrying cylinder (9) fixedly mounted on the mounting board (28), surrounding the electrical components (22) to be cooled, and having a ventilation opening (91) at a bottom thereof. An outer circumferential wall of the fixed carrying cylinder (9) is rotatably fitted with an gas channel distribution ring-shaped member (8) having a ring-shaped cavity (80), and the gas channel distribution ring-shaped member (8) is driven by a drive device to rotate and distribute a coolant gas to selectively perform cooling on one of the electrical components (22) to be cooled. The electrical cabinet having a solar power supply and a targeted cooling capability has reliable operation and a simple structure, thus enabling selective concentration of cooling and heat dissipation for a single element generating excessive heat in the electrical cabinet.

The invention discloses a slurry pump that injects both a large amount and a small amount, including a large reciprocating volume pump. The large reciprocating volume pump includes a large reciprocating part, a large pump body and a large pump inlet and outlet. In the large pump body, A small reciprocating piece fixed with the large reciprocating piece is arranged, a small pump body is arranged in the base of the large pump body, and a small pump inlet and outlet are arranged in the small pump body. The reciprocating positive displacement pump provided by the invention can realize both a large amount of injection and a small amount of color paste by using a large-section pump, which ensures the accuracy of the injection amount of color paste, especially the injection accuracy of a small amount of color paste. Compared with the prior art, the utility model has the advantages of high precision, simple structure, good leak-proof performance, high utilization rate in the length direction of the reciprocating pump cylinder, small elastic deformation of the pump bracket, which improves the stroke accuracy of the reciprocating pump, and solves the problem of gas collection in the pump. Seriously affect the micro-injection slurry accuracy. Likewise, the toning machine made of the pump is easy to use and occupies a small area.

The invention discloses an injection pump and a transmission device thereof.The transmission device comprises a screw rod, a semi nut, a moving component, a sliding seat, an elastic component and an electrical driving assembly; the semi nut and the moving component are both slidably arranged on the sliding seat; the moving component can move relative to the semi nut, and the elastic component is connected to the semi nut; when the electrical driving assembly drives the moving component t move to a first position in the direction far away from the screw rod, the semi nut is driven by the moving component to move to the position where the semi nut is separated from the screw rod; when the electrical driving assembly drives the moving component to move to a second position in the direction close to the screw rod, the semi nut is meshed with the screw rod under the action of elastic force of the elastic component, and the moving component and the semi nut are in clearance fit in the sliding direction of the moving component and the semi nut.The electrical driving assembly can be utilized for driving the semi nut to be completely separated from the screw rod, abrasion of threaded teeth is avoided, the service life is prolonged, operation is convenient to conduct, and labor is saved; the semi nut is meshed with the screw rod through elastic force, meshing reliability is guaranteed, the whole structure is simple, and process and machining difficulty is lowered.
