Abstract

The utility model relates to a pressure cooker timing means, a timer is provided with a controller consisting of an inductor, a spring plate which is arranged on the inductor base and provided with a magnetic steel and clutched with the upper end of the inductor as well as used for controlling the operation of a timer control plate and an insulating electric conducting element which is fixed through a spring and fitted with the spring plate by sliding manner; a timer with a controller, a battery and a dry spring tube are arranged inside a handle or a protection shell of the pressure cooker; a steam exhaust valve of the pressure cooker is provided with the tangent outer edge of a steam exhaust hole and locally embedded with the magnetic steel. The dry spring tube is near the steam exhaust valve. In the timer, an electric conducting sheet and the spring plate of the inductor are connected with the positive pole of the battery while the other electric conducting sheet is connected with the positive pole of a buzzer, the negative pole, the inductor and the spring with the insulating electric conducting element are connected with the negative pole of the battery, a power switch and the dry spring tube are connected with the negative pole of the battery in series, an indicator light is connected with the positive and negative poles of the battery.

Description

The pressure cooker timing means

The utility model relates to a kind of timing means that is used for pressure cooker.

It is reported that civilian pressure cooker does not all have timing means at present, therefore, need in use constantly to note viewing time that it has not only increased people's mental burden, and dangerous.

The utility model aims to provide a kind of reasonable in design, simple in structure, esy to use, safe and reliable, pressure cooker timing means accurately that gives the correct time regularly.

The purpose of this utility model is achieved in that is improved existing pressure cooker and timer, promptly on timer, be provided with by inductance, be located on the inductance seat be provided with magnet steel can with the spring leaf of the control timer control strip work of inductance upper end clutch and the controller that constitutes by the fixing insulated conductive member of joining with the spring leaf cunning of spring, in the handle of pressure cooker or protective case, be provided with the timer that has controller, battery and tongue tube, the air bleeding valve of pressure cooker is to have the air bleeding valve that tangent line steam vent outer rim part studs with magnet steel, tongue tube is near air bleeding valve, conducting strip in the timer is connected with the positive pole of battery with the spring leaf on the inductance, another conducting strip in the timer is connected with the positive pole of buzzer, the negative pole of buzzer, inductance, the spring that has insulated conductive member is connected with the negative pole of battery, power switch and tongue tube are connected on the negative pole of battery, and indicator lamp is connected on the both positive and negative polarity of battery.

The utility model and background technology relatively owing to adopted above-mentioned technical solution, therefore, have not only realized the timing of pressure cooker, and have had reasonable in design, simple in structure, esy to use, safe and reliable, advantage such as give the correct time accurately regularly.

Fig. 1 is structure of the present utility model and circuit diagram.

Fig. 2 is a scheme of installation of the present utility model

Describe a specific embodiment of the present utility model in detail below in conjunction with accompanying drawing.

Referring to Fig. 1, Fig. 2, on the handle 15 of pressure cooker 16, have cavity for dress tongue tube 7, the timer 2 that has controller, battery 3.On air bleeding valve 8, have 4 tangent line steam vents and a groove that is positioned at its outer rim, and in groove, be installed with magnet steel 9.On timer 2, be equipped with by inductance 11, be installed on the inductance seat 12 be fixed with magnet steel 9 can be with the spring leaf 6 of control timer control strip 14 work of inductance 11 upper end clutches and by the fixing controllers that constitute with the spring leaf 6 sliding insulated conductive members of joining 10 of spring 13.Insulated conductive member 10 is to be made by the copper sheet that the bottom is fixed with insulating barrier.Tongue tube 7 is near air bleeding valve 8.Conducting strip in the timer 2 is connected with the positive pole of battery 3 with the spring leaf 6 on the inductance 11, another conducting strip in the timer 2 is connected with the positive pole of buzzer 1, the negative pole of buzzer 1, inductance 11, the spring 13 that has an insulated conductive member 10 are connected with the negative pole of battery 3, and power switch 5 and tongue tube 7 are connected on the negative pole of battery 3.Indicator lamp 4 is connected on the both positive and negative polarity of battery 3.

During use, high-pressure pot cover is screwed, and air bleeding valve 8 is placed on the valve seat, make magnet steel 9 tongue tube 7 dorsad on the air bleeding valve 8, the pressure cooker 16 that water and food will be housed then is placed on also to light a fire on the stone or metal plate for standing a stove on as a precaution against fire and heats, knob with timer 2 forwards on the position of required time simultaneously, and presses power switch 5 and make indicator lamp 4 bright.The steam that produces in pressure cooker 16 makes air bleeding valve 8 go to its magnet steel 9 and just is switched on 7 pairs of seasonable power supplys of tongue tube, spring leaf 6 is slided to the insulation position of insulated conductive member 10 for 14 times by inductance 11 actuating and disconnecting timer control strips, timer 2 carries out work, automatically connect when timer 2 work buzzer 1 power supply behind the preset time and to send signal, the compressing tablet in the timer 2 quits work the spring leaf 6 pushed home timer 2s of controller.Turn off power supply and burning things which may cause a fire disaster then.
