During installation, the first end of the first connecting rod 41 is hinged between the two supporting ear blocks 341, and the first end of the first push rod 42 is connected to the second end of the first connecting rod 41. When the cam 32 rotates, the first connecting rod 41 is driven to swing, thereby driving the first push rod 42 to open or close the oil filter 10.

[0046] An outer flange 323 and a spiral impeller 322 are provided on the periphery of the cam 32. A notch 3231 is provided on the outer flange 323. The spiral impeller 322 is located at the notch 3231, and the first end of the spiral impeller 322 is connected to the first end of the outer flange 323. During the rotation of the cam 32, the outer flange 323 is driven and connected to the switch assembly 51 to control the switch assembly 51 to open or close, and the spiral impeller 322 is connected to the oil filter control mechanism 40 to drive the first push rod 42 to control the oil filter 10 to open or close.

[0047] Preferably, a drive shaft 414 is provided on the first push rod 42, and the drive shaft 414 is located at the bottom of the cam 32. During the rotation of the cam 32, the spiral impeller 322 can drive the drive shaft 414 to rotate along the supporting ear block 341, thereby driving the first push rod 42 to move, thereby opening the oil filter 10 for oil filtering.

[0048] In order to prevent the occurrence of interference, the first connecting rod 41 in this embodiment is provided with two parallel connecting rod blocks 411, and the two connecting rod blocks 411 are both provided with a first long hole 413 extending along the length direction of the connecting rod block 411. The first end of the first push rod 42 is provided with a connecting shaft 412, and the two ends of the connecting shaft 412 are respectively installed in the two first long holes 413. When the cam 32 drives the first connecting rod 41 to rotate, the first push rod 42 is retracted and extended along the first long hole 413 to facilitate opening the oil filter 10.

[0049] Combination Figures 1 to 3 ,as well as Figure 7As shown, a notch 11 is provided at the bottom of the oil filter 10, and the elastic valve of the oil filter 10 is located at the notch 11. A wedge block 421 is provided at the second end of the first push rod 42. When the cam portion of the cam 32 presses the drive shaft 414, the first push rod 42 rotates along the supporting ear block 341, and the first push rod 42 extends and retracts along the first long hole 413, thereby driving the wedge block 421 to insert into the notch 11 to open the elastic valve of the oil filter 10. When the cam portion of the cam 32 rotates over the drive shaft 414, under the action of the elastic valve of the oil filter 10, the wedge block 421 is reset, thereby driving the first push rod 42 and the first connecting rod 41 to reset, and the oil filter 10 is automatically closed.

[0050] Preferably, in this embodiment, an outer baffle plate 422 is provided on the outer periphery of the wedge block 421, and a through hole 423 is provided on the bottom of the wedge block 421. Through the action of the outer baffle plate 422, the oil flowing out of the oil filter 10 is conveniently surrounded on the outer periphery of the wedge block 421, and then enters the oil storage box 70 through the through hole 423.

[0051] Combination Figures 1 to 3 , Figure 6 and Figure 7 As shown, in order to install the temperature control mechanism 50, a first positioning shaft 321 is provided on the side of the cam 32 away from the knob 31 in this embodiment, and the driving mechanism includes a second connecting rod 52, which includes a vertical rod segment 521, a horizontal rod segment 522 and a pushing rod segment 523.

[0052] Among them, the vertical rod segment 521 is provided with a second long hole 5211 extending along the length direction of the vertical rod segment 521, and the first positioning axis 321 is passed through the second long hole 5211; the horizontal rod segment 522 is vertically connected to the bottom of the vertical rod segment 521; the first end of the pushing rod segment 523 is horizontally connected to the horizontal rod segment 522, and the second end of the pushing rod segment 523 is drivingly connected to the temperature controller 20.

[0053] During operation, when the knob 31 drives the cam 32 to rotate, the first positioning shaft 321 moves along the second long hole 5211, driving the horizontal rod segment 522 to move horizontally, and then driving the pushing rod segment 523 to move horizontally. During the horizontal movement of the pushing rod segment 523, the temperature controller 20 is driven to control the temperature.

[0054] Preferably, the push rod segment 523 in this embodiment is provided with a third long hole 5231 extending along the length direction of the push rod segment 523, and the temperature controller 20 is provided with a second positioning shaft 21 passing through the third long hole 5231. When the horizontal rod segment 522 moves horizontally, the second positioning shaft 21 moves along the third long hole 5231 and rotates at the same time, so as to drive the temperature controller 20 for temperature control.

[0055] In this embodiment, the horizontal rod section 522 is installed on the positioning plate 524, and the switch assembly 51 is installed on the positioning plate 524 and is located on the side of the cam 32. During the rotation of the cam 32, the cam 32 drives the switch assembly 51 to open.

[0057] Specifically, the switch assembly 51 in this embodiment includes a micro switch lever 511 , a micro switch 512 and an elastic return member 513 .

[0058] The micro switch lever 511 is mounted on the positioning plate 524 ; the micro switch 512 is mounted on the positioning plate 524 ; and the elastic reset member 513 is mounted between the micro switch 512 and the micro switch lever 511 .

[0059] When the cam portion of the cam 32 rotates to the micro switch lever 511, the outer flange 323 triggers the micro switch lever 511 to move, thereby compressing the elastic reset member 513, thereby opening the micro switch 512, thereby facilitating the opening of the electric heating tube 80 to heat the inner pot 60. In actual operation, when the knob 31 rotates to the oil filter stop A, the spiral impeller 322 is connected to the oil filter control mechanism 40, and the switch assembly 51 is closed.

[0060] A spiral impeller 322 is disposed on the side of the cam 32 , and the spiral impeller 322 forms a cam portion on the cam 32 , so as to drive the first connecting rod 41 and the switch assembly 51 to move.

[0061] Preferably, the elastic return member 513 in this embodiment is a spring. Of course, in other embodiments of the present invention, the elastic return member 513 can also be set as an elastic rubber block or other structures. As long as it is other deformation methods under the conception of the present invention, it is within the protection scope of the present invention.

[0062] According to the above structure, the present invention drives the cam 32 connected to the knob 31, and then controls the micro switch 512 through the cam 32 to control the on and off of the electric heating tube 80 of the electric fryer.

[0063] At the same time, the cam 32 connected to the control knob 31 is driven, and the temperature of the thermostat 20 is controlled by a driving mechanism connected to the cam 32, so as to realize the oil temperature control in the electric fryer.

[0064] At the same time, the control knob 31 drives the cam 32 connected thereto, and the cam 32 drives the oil filter control mechanism 40 to control the operation of the oil filter 10 .

[0065] Preferably, the cam 32 in this embodiment can rotate forward or reverse, and the rotation angle of the cam 32 is between 0° and 270°. During operation, the spiral impeller 322 at A limits the cam 32 to continue rotating beyond the A gear, and the second long hole 5211 at D limits the cam to continue rotating beyond the D gear.

[0066] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: the oil temperature adjustment and oil filtering in the present invention are controlled by a knob, and no misoperation occurs; the cam connected to the knob controls the oil filtering to ensure that the electric fryer is not powered (not working), and is powered only during the cooking stage. The cooking temperature adjustment range of the present invention is 80-190°C, and a cleaning gear (80°C) is set. Even if you forget to turn off the machine, the water in the pot will not dry up because the water is not boiling, which is safer.

[0067] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
