In order to make the technical means, creative features, achievement goals and effects realized by the present invention easy to understand, the present invention will be further described below with reference to the specific embodiments.
 see Figure 1-4 , the present invention provides a technical solution: an electric pressure cooker with a lid closing detection device, comprising a pressure cooker body 1 and a pressure cooker cover 2, the pressure cooker body 1 is provided with the pressure cooker cover 2 on the top, and the pressure cooker body 1 The left and right sides are symmetrically provided with handle bars 3, the handle bars 3 are fixedly connected with the pressure cooker body 1, the front of the pressure cooker body 1 is provided with a control panel 4, and the upper left side of the control panel 4 is provided with an indication Lamp 5, the upper right side of the control panel 4 is provided with a warning speaker 6; the top of the pressure cooker cover 2 is provided with a fixed convex column 7, the fixed convex column 7 is fixedly connected with the pressure cooker cover 2, the pressure cooker cover The bottom edge of 2 is provided with a plurality of touch protrusions 8 , and a lid closing detection assembly 9 is arranged directly below the touching protrusions 8 , and the lid closing detection assembly 9 is fixedly connected to the inside of the pressure cooker body 1 .
 see image 3 , the lid closing detection assembly 9 includes a fixed seat box 10 , the top of the fixed seat box 10 is provided with a fixed groove 11 , and the size of the fixed groove 11 corresponds to the touch protrusion 8 . Through such a design, the fixing groove 11 can be used to touch the protruding post 8 for cooperation, the closed cover can be detected, and the closure can be performed.
 see image 3 The interior of the fixing groove 11 is provided with an elastic electrified contact piece 12 , the left end of the elastic electrified contact piece 12 is connected to the power cord 13 , and the power cord 13 is connected to the warning speaker 6 and the indicator light 5 . Through such a design, when the elastic electrified contact piece 12 cannot be squeezed by touching the protruding post 8, the warning speaker 6 and the indicator light 5 will be activated to warn the user.
 see image 3 The bottom end of the fixing groove 11 is provided with a conductive copper plate 14 , the bottom of the conductive copper plate 14 is connected to the power line 13 , and the left end of the power line 13 is connected to the indicator light 5 . Through such a design, when the contact protrusion 8 presses the elastic electrified contact piece 12, the indicator light 5 lights up, indicating that the cover has been sealed.
 see figure 1 , the bottom of the pressure cooker body 1 is provided with a fixed foot 15, and the fixed foot 15 is made of elastic rubber material. Through such a design, the fixed feet 15 can be used to enhance the stability and insulation of the entire device, making it safer to use.
 see figure 2 , the top of the pressure cooker body 1 is provided with a sealing block 16 , and the sealing block 16 is fitted with the pressure cooker cover 2 . Through such a design, the sealing performance of the equipment can be enhanced as a whole by the additional sealing gasket 16 .
 see figure 1 , the top of the pressure end cover 2 is provided with a fixed column block 17, the bottom of the fixed column block 17 is provided with a rotating hinge 18, the bottom of the rotating hinge 18 is rotatably connected to the buckle convex strip 19, and the buckle convex The bottom of the bar 19 is connected to the magnet block 20, and the top of the control panel 4 is provided with a magnetic adsorption part 21, and the magnetic adsorption part 21 is recessed inward as a whole. Through this design, the magnet block 20 on the snap-on protruding strip 19 and the magnetic adsorption part 21 can be used for adsorption, so that the touch protrusion 8 at the bottom of the pressure end cap can be accurately snapped into the fixing groove 11, which is more convenient to use.
 see Figure 4 , the inner side of the pressure end cover 2 is provided with a plurality of touch protrusions 8, and the touch protrusions 8 are evenly distributed at equal distances. Through such a design, the sealing effect of the closing cover can be enhanced by using a plurality of touching protrusions 8 .
 In the electric pressure cooker with the lid closing detection device according to the present invention, during use, a plurality of evenly distributed touch protrusions 8 are added to the bottom of the pressure cooker lid 2 , and at the same time, a closed lid is added to the inside of the pressure cooker body 1 . The lid detection assembly 9 can be sealed and closed by the pressure cooker lid 2 during use. When the lid is closed, the contact protrusions 8 can completely squeeze the elastic electrified contact piece 12 inside the fixing groove 11, and the elastic electrified contact piece 12 can be used to connect with the conductive The copper plate 14 realizes the circuit closure, so that the indicator light 5 lights up, indicating that it has been closed. When the elastic electrified contact piece 12 in the fixed groove 11 is not pressed by the contact bump 8, the warning speaker 6 and the indicator light 5 will be activated, warning User, the principle is simple, and at the same time, a fixed column block 17 is added to the pressure cooker cover 2, and a rotating hinge 18 and a snap rib 19 are added, and a magnet block 20 is added on the snap rib 19, and the magnet block 20 can be used. Adsorbing with the magnetic adsorption part 21 effectively urges the contact protrusions 8 at the bottom of the pressure cooker cover 2 to be placed in alignment with the fixing grooves 11 , which can ensure that the cover is closed and sealed, and has strong practicability.
The pressure cooker body-1, the pressure cooker cover-2, the handle bar-3, the control panel-4, the indicator light-5, the warning speaker-6, the fixed convex column-7, the touching convex column-8, the lid closing detection of the present invention Component-9, fixed seat box-10, fixed groove-11, elastic electrified contact-12, power cord-13, conductive copper plate-14, fixed foot-15, sealing block-16, fixed column block-17, Rotating hinge-18, buckle convex strip-19, magnet block-20, magnetic adsorption part-21, the components are all common standard parts or components known to those skilled in the art, and their structures and principles are all accessible to those skilled in the art According to the technical manual or through conventional experimental methods, the problem solved by the present invention is that the sealing detection effect of the electric pressure cooker lid body in the prior art is not good, and it does not have an early warning function, and the use limitation is large. It will not only waste a lot of electric energy, but also the cooked food will be half-cooked, resulting in waste. This kind of equipment is equipped with a cover closing detection component inside the pressure cooker body, and at the same time, a corresponding touch convex column is added on the pressure end cover. During the process of contact between the two, it will warn and detect whether it is closed. The overall structure is simple and the function is simple. Strong sex.
