Embodiment Construction

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] The present invention is as figure 1 , figure 2 As shown, it includes a pot body 1, an outer pot 2 placed in the pot body 1, and a pressure regulator 4 fixed on the upper part of the outer pot 2. The pressure regulator 4 has a through hole 46; the outer pot 2 corresponds to the pressure regulator. The bottom of 4 is fixed with switch 5, and push rod 6 vertically passes through the through hole 46 of pressure regulator 4, back-moving spring 7, through hole 21 on the pot edge of outer pot 2, and one end of push rod 6 contacts with switch 5, The other end protrudes on the pot edge of the outer pot 2. Push rod 6 can move up and down in through hole 46, through hole 21. There is a guide groove 31 on the pot cover 3. During the closing process of the pot cover 3, it will press the ejector rod 6 to make the switch 5 in the disconnected state. Directl...

Abstract

The invention discloses a detector for detecting the pressure and whether a cover is closed in place of an electric pressure cooker, which comprises an outer pot, a cover and a pressure regulator with an ejector rod. A switch is fixed on the outer pot, corresponding to a part below the pressure regulator. The ejector rod moves vertically to penetrate through a through hole of the pressure regulator and a through hole in the edge of the outer pot. One end of the ejector rod is contacted with the switch, and the other end of the ejector rod protrudes from the edge of the outer pot. The cover is closed in place. The guide slot of the cover is positioned right above the end of the ejector rod. The pressure regulator is composed of a casing, a spring, an ejector pin and a screw rod. The casing is provided with a through hole. The two ends of the through hole are provided with inwardly extending steps. The ejector pin is installed in the through hole. The step on the ejector pin is limited by the step on one end of the through hole, while one end of the ejector pin is contacted with the switch after passing through the through hole. One end of the spring is sheathed on the ejector pin, while the other end of the spring is sheathed on the step of the through hole on the casing. The detector is characterized by being low in cost and having multiple functions of safeguard, and can be suitable for the pressure control and the safeguard for opening and closing the cover of the electric pressure cooker.

Description

technical field [0001] The invention relates to the field of electric pressure cookers, in particular to a pressure detection and lid closing position detection device for electric pressure cookers. Background technique [0002] At present, the electric pressure cooker on the market usually uses a pressure switch or a displacement sensor to detect the displacement of the electric heating plate at the bottom of the outer pot to realize the pressure control in the pot; a micro switch or a magnetic reed switch is used between the pot cover and the shell to realize the detection of the lid closing position. . Such as Chinese patent 200320116811.5, title is called " the pressure control device of electric pressure cooker ", discloses a kind of pressure control device of electric pressure cooker, and pressure bracket is installed on outer pot, and adjusting screw rod is installed on pressure bracket, and pressure switch is installed on heating plate. In the pressure state, the do...
