[0002] Electric griddles are a common food processing appliance used in many households, capable of both baking and frying food. An electric griddle typically consists of two plates connected by a hinge, allowing for simultaneous heating of both sides of flatbreads. To remove smoke during use, the upper plate is usually opened or a smoke extraction device is added. For example, utility model patent CN215077710U discloses a smoke extraction electric griddle, comprising: a griddle body, including an upper and lower griddle body movably connected; a first and second receiving cavity recessed within the lower griddle body, with multiple smoke inlets on the side wall of the first receiving cavity, connecting the first and second receiving cavities; and a negative pressure fan located on the inner wall of the lower griddle body, one end of which connects to the second receiving cavity, and the other end connects to the outside.

[0029] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0030] refer to Figures 1 to 9An adjustable micro-piezoelectric griddle includes a lower griddle body 1 and an upper griddle body 2, which are hinged together. A handle 204 is provided on the top of the upper griddle body 2, allowing the user to hold it and open or close the upper griddle body 2 and the lower griddle body 1. The top of the lower griddle body 1 has a recessed cavity 101, and the bottom of the upper griddle body 2 has a protruding flange structure 203. When the lower griddle body 1 and the upper griddle body 2 are engaged, the flange structure 203 and the cavity 101 are interlocked, forming a closed heating chamber 4. A sealing ring 7 is provided between the edge of the flange structure 203 and the edge of the cavity 101, and the sealing ring 7 is embedded in the top of the lower griddle body 1. The sealing ring 7 ensures good sealing performance of the heating chamber 4.

[0031] Heating devices 3 are installed inside both the upper pan body 2 and the lower pan body 1. The heating devices 3 are electric heating coils, which are existing technologies and will not be described in detail here. The upper pan body 2 is provided with a vertically penetrating exhaust duct 201. The lower opening of the exhaust duct 201 is located on the bottom surface of the flange structure 203. A movable cavity 202 is opened at the top of the upper pan body 2. The upper opening of the exhaust duct 201 is located on the bottom inner wall of the movable cavity 202. An exhaust switching mechanism 5 is movably installed in the movable cavity 202. The exhaust duct 201 is used to connect the heating cavity 4 and the exhaust switching mechanism 5.

[0032] The smoke extraction switching mechanism 5 includes an operating housing 51, a filter body 52, a direct exhaust pipe 53, and a one-way valve 54. The operating housing 51 includes a filter box 511 and an oil collection cover 512. The filter box 511 has an upward-facing opening, and its inner cavity is for placing the filter body 52. ​​The oil collection cover 512 is detachably connected to the filter box 511, covering the opening of the filter box 511 so that the filter body 52 is located in the inner cavity of the operating housing 51. A filtration area 502 is provided on the bottom surface of the filter box 511, and the filtration area 502 includes several through-hole filter holes 503. The straight drain pipe 53 and the one-way valve 54 are both located in the inner cavity of the filter box 511. Furthermore, the filter area 502, the straight drain pipe 53 and the one-way valve 54 are staggered, so that each filter hole 503, the straight drain pipe 53 and the one-way valve 54 are interconnected with the inner cavity of the operating shell 51. An air outlet 501 is provided through the oil collection cover 512.

[0033] The filter body 52 has two through-holes 504, which respectively engage with the straight drain pipe 53 and the one-way valve 54, thus guiding the filter body 52 to be placed correctly in the inner cavity of the filter box 511. The filter box 511 and the oil collection cover 512 can be connected by a screw-in snap-fit ​​or a threaded connection, so that the user can replace the filter body 52 after opening the operating shell 51. Preferably, the filter body 52 can be a filter core material such as PP cotton or activated carbon filter.

[0034] Preferably, the one-way valve 54 includes a micro-pressure smoke passage pipe 541, a micro-pressure positioning element 542, and a micro-pressure cover 543. The micro-pressure positioning element 542 is fixedly connected to the inner wall of the micro-pressure smoke passage pipe 541 and has three smoke exhaust holes 505 arranged in a ring array. The micro-pressure cover 543 is movably disposed on the inner wall of the micro-pressure smoke passage pipe 541. The micro-pressure positioning element 542 has a through-hole 506, and the micro-pressure cover 543 has a stroke column 507 that slides within the stroke column 506 to guide the movement direction of the micro-pressure cover 543. One end of the stroke column 507 passing through the micro-pressure positioning element 542 has a limiting part 508. The top surface of the limiting part 508 abuts against the bottom surface of the micro-pressure positioning element 542 to limit the displacement stroke of the micro-pressure cover 543. When the air pressure in the heating chamber 4 is normal, the micro-pressure cover 543 and the micro-pressure positioning member 542 are in contact, so that the micro-pressure cover 543 covers each smoke exhaust hole 505; when the air pressure in the heating chamber 4 is excessive, the micro-pressure cover 543 is pressed upward and thus disengages from the micro-pressure positioning member 542, and the micro-pressure cover 543 and the micro-pressure positioning member 542 are in clearance fit, so that the micro-pressure cover 543 opens the smoke exhaust hole 505.

[0035] The operating housing 51 rotates about its axis so that any one of the filter zone 502, the straight exhaust pipe 53 and the one-way valve 54 corresponds to the flue duct 201, so that the flue switching mechanism 5 has three modes: straight exhaust mode, micro pressure mode and filter mode.

[0036] In direct exhaust mode, the direct exhaust pipe 53 is connected to the exhaust duct 201. The oil fumes in the heating chamber 4 are discharged to the outside of the electric griddle through the exhaust duct 201, the direct exhaust pipe 53 and the air outlet 501 in sequence, ensuring that the oil fumes can be discharged in a timely manner.

[0037] In low-pressure mode, the one-way valve 54 is connected to the exhaust duct 201. The oil fumes in the heating chamber 4 enter the one-way valve 54. When the air pressure in the heating chamber 4 exceeds the pressure peak of the one-way valve 54, the one-way valve 54 opens. The high-pressure gas in the heating chamber 4 is discharged to the outside of the electric griddle through the outlet hole of the one-way valve 54, ensuring that the oil fumes are properly compressed in the heating chamber 4 and discharged when there is overpressure.

[0038] In filtration mode, the filtration zone 502 is connected to the exhaust duct 201. The oil fumes in the heating chamber 4 are discharged to the outside of the electric griddle through the exhaust duct 201, the filter holes 503 of the filtration zone 502, the filter body 52 and the air outlet 501. The filter body 52 is used to filter oil particles and solid particles in the oil fumes to ensure that the discharged oil fumes are more environmentally friendly.

[0039] Users can rotate the operating shell 51 as needed, and the smoke extraction switching mechanism 5 can be switched to direct exhaust mode, micro-pressure mode or filtration mode to achieve flexible switching of multiple smoke extraction modes, ensuring the optimal smoke extraction effect under different cooking needs and improving the user experience.

[0040] Preferably, the movable cavity 202 allows the operating housing 51 to rotate. A gear shift assembly 6 is provided between the inner wall of the movable cavity 202 and the outer wall of the operating housing 51. The gear shift assembly 6 includes a gear shift ring 61 and an elastic positioning pin 62. The gear shift ring 61 is detachably connected to the movable cavity 202, and the gear shift ring 61 and the operating housing 51 are in abutting or clearance fit. The elastic positioning pin 62 is provided on the inner wall of the gear shift ring 61, and a gear shift groove 8 is provided on the outer wall of the operating housing 51. The end of the elastic positioning pin 62 extends out of the outer side of the gear shift ring 61 and is inserted into the gear shift groove 8. The elastic positioning pin 62 is a spring pin, which is prior art and will not be described in detail here. There are three elastic positioning pins 62 and three gear shift grooves 8, and each elastic positioning pin 62 and each gear shift groove 8 is evenly distributed along the circumference of the gear shift ring 61. The setting of the gear component 6 allows the user to pause when switching between different modes while rotating the operating shell 51. This ensures that when the smoke exhaust switching mechanism 5 switches to the direct exhaust mode, micro-pressure mode, or filtration mode, the operating shell 51 is positioned by the corresponding elastic pin, allowing the user to clearly feel the gear change and making it easier for the user to control the operating shell 51 to switch between different modes.

[0041] Preferably, the upper ends of the straight exhaust pipe 53 and the one-way valve 54 extend to the outer side of the top surface of the filter body 52, ensuring that the flue gas passing through the straight exhaust pipe 53 and the flue gas passing through the one-way valve 54 are preferentially discharged through the exhaust port 501, avoiding the flue gas from being trapped in the space where the filter element is located; the lower ends of the straight exhaust pipe 53 and the one-way valve 54 extend to the outer side of the bottom surface of the operating housing 51, ensuring that the straight exhaust pipe 53, the one-way valve 54 and the filter area 502 can work independently according to their respective functions.

[0042] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
