DETAILED DESCRIPTION

[0024] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0025] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0026] This embodiment mainly describes the pressure detection structure of the pressure cooker cover, which is as follows:

[0027] The pressure cooker lid with a pressure detection structure comprises a lid body 1 , on which a handle 11 is arranged, and the handle 11 is convenient for people to pick up the lid body 1 .

[0028] A mounting seat 12 is provided on the cover body 1, and a detection probe 2 is provided inside the mounting seat 12. The detection probe 2 extends from the bottom end of the mounting seat 12 and passes through the cover body 1. When the cover body 1 is covered on the pot body, the bottom end of the detection probe 2 is located inside the pot body, which can effectively detect the pressure and temperature inside the pot body.

[0029] Furthermore, the detection probe 2 is composed of a temperature sensing probe and a pressure sensing probe. The temperature sensing probe senses the temperature inside the pot, and the pressure sensing probe senses the pressure inside the pot.

[0030] A circuit board 3 is disposed in the mounting seat 12 , and the detection probe 2 is electrically connected to the circuit board 3 . The detection probe 2 transmits the sensed pressure information and temperature information to the circuit board 3 .

[0031] The mounting base 12 is provided with an upper cover 4 which covers the mounting base 12 . The upper cover 4 is detachably connected to the mounting base 12 . Furthermore, the upper cover 4 is fixedly connected to the mounting base 12 by screws, and the circuit board 3 is fixedly connected to the bottom of the upper cover 4 .

[0032] A display screen 41 is provided on the upper cover 4. The display screen 41 is located on the top surface of the upper cover 4. The display screen 41 is electrically connected to the circuit board 3. The display screen 41 displays the temperature information and pressure information detected by the detection probe 2. The user can clearly understand the temperature and pressure conditions in the pot body through the display screen 41.

[0033] The display screen 41 covers the entire upper cover 4 , and the display screen 41 is a touch screen. The user can adjust the content displayed on the display screen 41 or operate it through the touch screen.

[0034] Or if the display screen 41 is just a single screen, then a button 42 is also provided on the upper cover 4 , and the button 42 is electrically connected to the circuit board 3 . The button 42 can control the content displayed on the display screen 41 through the circuit board 3 .

[0035] An alarm 13 is arranged in the mounting base 12 and is electrically connected to the circuit board 3. When the pressure sensing probe detects that the pressure in the pot is too high, the circuit board 3 controls the alarm 13 to sound an alarm to remind the user to turn off the fire.

[0036] The mounting seat 12 is provided with an assembly groove 121 , and the alarm 13 is fixedly connected in the assembly groove 121 .

[0037] A battery 14 is also provided in the mounting base 12 , and the battery 14 is used to supply power to the circuit board 3 , the detection probe 2 and the alarm 13 .

[0038] Since the upper cover 4 is detachably connected to the mounting base 12, the upper cover 4 can be removed for battery replacement.

[0039] The mounting seat 12 is provided with a battery mounting portion 15 , and the battery mounting portion 15 is provided with a mounting hole 16 , and the battery 14 is placed in the mounting hole 16 .

[0040] Furthermore, a positive spring connector 31 is provided on the circuit board 3, and the other end of the positive spring connector 31 is against the positive pole of the battery 14. A negative connector 32 is provided in the battery mounting portion 15, and one end of the negative connector 32 is against the negative pole of the battery 14, and the other end of the negative connector 32 is electrically connected to the circuit board 3.

[0041] An annular light strip 17 is provided on the mounting base 12, and the annular light strip 17 is electrically connected to the circuit board 3 and the battery 14. The annular light strip 17 changes color through the control of the circuit board 3. For example, when the pot body is in normal use, the color of the annular light strip 17 is green. When the alarm 13 sounds, the color of the annular light strip 17 will change to red.

[0042] The outer sleeve of the mounting base 12 is provided with a heat insulating sleeve 18, which covers the bottom surface and the side wall of the mounting base 12, which not only improves the aesthetics, but also can isolate the high temperature generated by the pressure cooker when in use, thereby preventing the internal temperature of the mounting base 12 from being too high.

[0043] When in use, press and hold button 42 for three seconds, the detection system starts working, and display screen 41 lights up. Display screen 41 is in the pressure value interface by default. Press and hold button 42 for three seconds again, display screen 41 switches the display content, and the display screen enters the temperature value interface. Press and hold button 42 for three seconds again, display screen 41 switches the display content again, and the display screen enters the timing interface. After switching to a different interface each time, it stays for three seconds to start working. Finally, press and hold button 42 for ten seconds to shut down the detection system.

[0044] When in the timing interface, the timing time is increased by pressing the button 42. Each time the button 42 is pressed, the timing time is increased by one minute. When the timing time exceeds ten minutes, each time the button 42 is pressed, the timing time is increased by five minutes. After the time setting is completed, it stays for three seconds and the timing starts. When the timing ends, the alarm 13 will sound and the ring light 17 will turn red to remind the user to turn off the fire.

[0045] In any case, as long as the pressure in the pot is too high, the alarm 13 will sound an alarm, the annular light strip 17 will turn red, and the annular light strip 17 will flash to further remind the user to turn off the fire in time to prevent accidents.
