Abstract

The utility model discloses a portable pressure steam sterilizer for disinfecting and sterilizing, comprising an upper cover, an outer shell, and inner drum, an overpressure protective valve, a pressure gauge and an electric heater. The portable pressure steam sterilizer for disinfecting and sterilizing is characterized in that the inner cavity of the outer shell is provided with a temperature sensor or a pressure sensor, and the temperature sensor or the pressure sensor is connected with a controller composed of a signal generating circuit, a comparison circuit, an executive circuit and a time control circuit. The utility model can realize automatic switch-over without noise pollution, save energy source, and avoid having scald accident.

Description

Portable pressure steam steriliazer

This utility model relates to medical disinfecting, sterilization field, particularly a kind of portable pressure steam steriliazer.

In departments such as small-sized hospital, private clinics, one removes and all uses portable pressure steam steriliazer at the 126--138 degree, and to the article sterilization processing, this disinfector is owing to be to adopt pressure valve pressure release mode to control under the condition of 1.4KG pressure, so there is following shortcoming, pressure valve was opened after 1 pressure reached 1.4KG, emitted a shrill cry, and sound pollution is arranged, a large amount of steam ejections after opening, 2 pressure valve is arranged, personal scald accident takes place easily, and 3 disinfector continuous operations waste energy.

The purpose of this utility model provide a kind of reach give level pressure power after, the portable pressure steam steriliazer that can cut off the electricity supply automatically.

This utility model is to realize like this; it comprises loam cake; shell; interior bucket; the overvoltage protection valve; Pressure gauge and electric heater is characterized in that being provided with temperature or pressure transducer at the inner chamber of shell, and this temperature or pressure transducer are connected with the controller of being made up of signal generating circuit, comparison circuit, executive circuit and time control circuit.

This utility model can be realized automaticallying switch owing to increased by a cover controller on common steam sterilizer, and noise-less pollution, the saving energy can also be avoided the generation of personal scald accident.

Below in conjunction with accompanying drawing this utility model is further described,

Fig. 1 is the structural representation of portable pressure steam steriliazer,

Fig. 2 is the circuit diagram of portable pressure steam steriliazer,

As Fig. 1--it comprises loam cake 1 shown in 2, shell 2, interior bucket 3, overvoltage protection valve 4, Pressure gauge 5 and electric heater 6, loam cake 1 is provided with overvoltage protection valve 4 and the Pressure gauge 5 that pressure release is used, interior bucket 3 is placed in the intracavity of shell 2, between loam cake 1 and shell 2, be provided with sealing ring 7, inner chamber at shell 2 is provided with temperature or pressure transducer 8, this temperature or pressure transducer 8 are connected with the controller of being made up of power circuit, comparison circuit, executive circuit and time control circuit, and wherein executive circuit comprises SCR1 and relay J 1; Power circuit comprises transformator B, integrated package 7806, diode D1--D4 and capacitor C1--C2, comparison circuit comprises integrated package 741, Zener diode D5--D7, SCR2, resistor R 2--R7, audion BG1 and adjustable resistor RW, and the input 741 has inserted pick off 8; Time control circuit comprise SCR3, resistor R 9--R11, capacitor C3-C6, audion BG2,, integrated package 555,4040,4017 and buzzer 9.During work, desire the disinfectant article place in the bucket 3, energized again after loam cake 1 screws with shell 2, as the voltage VQ at pick off 8 two ends during greater than the voltage VW at adjustable resistor RW two ends, J1 does not work, J1-1, SCR1 conducting, electric heater 6 work; As VQ during less than VW, the J1 adhesive, J1-1 disconnects, SCR1 ends, and electric heater 6 is not worked, and meanwhile J1-2 connects and triggers the SCR3 conducting, after pressure in the disinfector or temperature decline, VQ is greater than VW, and the J1 dead electricity is not worked, J1-1 connects electric heater 6 and reworks, reach the disinfecting time of setting after, the IC4 output signal, the BG2 conducting, buzzer 9 sends alarm sound, the signal triggering SCR2 conducting that while IC4 sends, guarantee the J1 adhesive, electric heater 6 quits work.

Claims

1; a kind of portable pressure steam steriliazer; it comprises loam cake; shell; interior bucket, overvoltage protection valve, Pressure gauge and electric heater; it is characterized in that being provided with temperature or pressure transducer at the inner chamber of shell, this temperature or pressure transducer are connected with the controller of being made up of signal generating circuit, comparison circuit, executive circuit and time control circuit.
