Abstract
The utility model discloses an automatic pressure-controlling drying cabinet, which belongs to a drying cabinet. The structure of the drying cabinet comprises a cabinet body and a vacuum pump, the cabinet body is connected with the vacuum pump through a suction tube, a pressure display is arranged on the cabinet body, a control box is arranged on the right side of the cabinet body, a pressure sensor, a controller and a relay are arranged in the control box, one end of the pressure sensor is extended into the cabinet body, the upper part of the control box is provided with a socket, the vacuumpump is connected with the control box through a power plug plugged in the socket, and the pressure sensor, the controller, the relay and the vacuum pump are electrically connected. Compared with theprior art, the drying cabinet does not need to be manually operated, the power supply of the vacuum pump can be automatically switched off or on when the pressure in the drying cabinet is lower or higher than a set pressure value, and the drying cabinet is characterized by convenient use, reasonable design, simple structure and the like, so the drying cabinet is worth popularization and application.
Description
Technical field
The utility model relates to a kind of drying box, especially a kind of automatic pressure-controlled drying box.
Background technology
Present employed drying box mostly is temperature automatically controlled drying box, the drying box that vacuumizes also is to have temperature automatically controlled function, but do not have automatic pressure-controlled function, when work, under the drive of vavuum pump, air in the drying box is extracted out, and show the vacuum that extracts at the dial plate of drying box, when the drying box internal pressure reaches the vacuum degree condition of setting, need hand off vavuum pump workpiece power supply, vavuum pump is quit work, and when the pressure in the drying box is higher than the vacuum degree condition of setting, the vacuum-pump power supply of need manually closing, very inconvenient.At present, good solution is not also arranged.
The utility model content
Technical assignment of the present utility model is to provide a kind of automatic pressure-controlled drying box at above-mentioned deficiency of the prior art, and this automatic pressure-controlled drying box has manual, automatic pressure-controlled function, the characteristics easy to use of not needing.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises casing and vavuum pump, casing links to each other with vavuum pump by suction pipe, casing is provided with pressure display unit, the right side of casing is provided with control box, be provided with pressure sensor, controller and relay in the control box, one end of described pressure sensor extend in the casing, control box top is provided with jack, vavuum pump inserts jack by attaching plug and links to each other with control box, and described pressure sensor, controller, relay and vavuum pump are electrically connected.
Automatic pressure-controlled drying box of the present utility model is compared with prior art, has following outstanding beneficial effect: do not need manually, when the pressure in the drying box is below or above the force value of setting, automatic disconnection or connection vacuum-pump power supply, easy to use, reasonable in design, characteristics such as simple in structure.
Description of drawings
Accompanying drawing 1 is the structural representation of automatic pressure-controlled drying box;
Accompanying drawing 2 is theory structure block diagrams of automatic pressure-controlled drying box;
Description of reference numerals: 1, casing, 2, suction pipe, 3, vavuum pump, 4, control box, 5, plug, 6, relay, 7, controller, 8, pressure sensor, 9, pressure display unit.
The specific embodiment
Explain below doing with reference to Figure of description 1,2 pairs of automatic pressure-controlled drying boxes of the present utility model of accompanying drawing.
Automatic pressure-controlled drying box of the present utility model, its structure comprises casing 1 and vavuum pump 3, casing 1 links to each other with vavuum pump 3 by suction pipe 2, casing 1 is provided with pressure display unit 9, the right side of casing 1 is provided with control box 4, be provided with pressure sensor 8, controller 7 and relay 6 in the control box 4, one end of described pressure sensor 8 extend in the casing 1, control box 4 tops are provided with jack, vavuum pump 3 inserts jack by attaching plug 5 and links to each other with control box 4, and described pressure sensor 8, controller 7, relay 6 and vavuum pump 3 are electrically connected.
As required controller 7 is provided with a force value, pressure sensor 8 detects the pressure in the casing 1, signal is passed to controller 7, and when pressure was lower than the force value of setting, relay 6 disconnected, thereby vavuum pump 3 outages quit work, when pressure was higher than the force value of setting, relay 6 closed, thus vavuum pump 3 power connections, start working, reach automatic pressure-controlled.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
