[0035] Please combine Figures 1 to 4 As shown, the present application first provides an oil level detection structure, including an oil cup bracket 10, an oil cup 20, a detection assembly 30 and a central control panel, wherein the oil cup 20 is detachably arranged on the oil cup bracket 10; the detection assembly 30 includes a mounting seat 31, a detection block 32 and an elastic member 33, wherein the mounting seat 31 is fixed to the oil cup bracket 10, the detection block 32 is slidably arranged on the mounting seat 31, the elastic member 33 is arranged between the mounting seat 31 and the detection block 32, and the detection block 32 is electrically connected to the central control panel; the detection assembly 30 has a disengaged state and a detection state, wherein in the disengaged state, the oil cup 20 is disengaged from the detection block 32; in the detection state, the oil cup 20 is tightly abutted against the detection block 32, and the elastic member 33 is in an elastic deformation state, so as to detect the oil level inside the oil cup 20 through the detection block 32.
[0036] In the present application, the oil level inside the oil cup 20 can be detected through the detection block 32, and the user can be prompted through the central control panel when the oil is full, thereby avoiding the oil overflowing from the oil cup 20; in addition, the elastic member 33 is in an elastic deformation state in the detection state, and the elastic member 33 can drive the detection block 32 to press against the oil cup 20, thereby ensuring the stable fit between the two, thereby achieving the effect of improving the detection stability and accuracy of the detection block 32.
[0037] Specifically, the detection block 32 is a non-contact liquid level detection component. When the detection block 32 is in close contact with the oil cup 20, it can measure the capacitance and output the measured signal to the central control panel, so that the user can directly observe whether the oil is full on the central control panel.
[0038] More specifically, the non-contact liquid level detection uses the inductive capacitance of the liquid to detect whether there is liquid. When there is no liquid approaching the PCB sensing plate 322 of the detection block 32, the PCB sensing plate 322 has a certain static capacitance due to the existence of distributed capacitance.
[0039] When the liquid level slowly rises to approach the PCB sensing plate 322, the parasitic capacitance of the liquid will be coupled to this static capacitance, causing the capacitance value of the PCB sensing plate 322 to increase. After the changed capacitance signal is converted into a signal, the change can be detected and judged according to the corresponding algorithm. When the change exceeds a certain threshold, it is considered that the liquid level has reached the sensing point, that is, the oil cup 20 is full of oil, and an oil level full prompt alarm is issued through the central control panel.
[0040] In addition, if the oil cup 20 is not in contact with the detection block 32, that is, the oil cup 20 is not installed in place, the PCB sensing plate 322 detects the corresponding capacitance change and transmits the output signal to the central control panel, which issues a prompt alarm that the oil box is not detected.
[0041] Please combine Figure 1 as well as Figure 3 As shown, in some embodiments, the oil cup bracket 10 has an opening 11 , the oil cup 20 is slidably connected to the oil cup bracket 10 through the opening 11 , and the mounting seat 31 is located on a side away from the opening 11 along the sliding direction of the oil cup 20 .
[0042] As the oil cup 20 is slidably inserted into the oil cup bracket 10, the oil cup 20 abuts against the detection block 32 and further squeezes the detection block 32, so as to cause the elastic member 33 to undergo elastic deformation until the oil cup 20 is installed in place. This ensures that after the oil cup 20 is installed in place, the detection block 32 abuts against the oil cup 20 under the elastic force of the elastic member 33, so as to improve the detection stability and accuracy of the detection block 32.
[0043] Of course, in some other embodiments, the detection component 30 may also be set at other positions, for example: the detection component 30 is located on the side of the oil cup 20, and the detection block 32 has a chamfer on the side close to the opening 11, so that the detection block 32 can be squeezed as the oil cup 20 is inserted into the oil cup bracket 10.
[0044] Please combine Figure 3 as well as Figure 4 As shown, in some embodiments, the elastic member 33 is a compression spring; as the oil cup 20 slides into the oil cup bracket 10, the oil cup 20 abuts against the detection block 32 and further squeezes the detection block 32 to compress and deform the compression spring.
[0045] Of course, in some other embodiments, depending on the structure and setting position of the detection component 30, the elastic member 33 may also be a tension spring, and the present application does not make further limitations here.
[0046] Please combine Figure 5 as well as Figure 6 As shown, in some embodiments, the detection block 32 includes a slider 321, a PCB sensing plate 322 and a signal line 323. The slider 321 is slidably connected to the mounting base 31 along the sliding direction of the oil cup 20. The PCB sensing plate 322 is fixed to the end surface of the slider 321 close to the oil cup 20. The PCB sensing plate 322 is used to be in close contact with the oil cup 20 to detect the capacitance of the oil cup 20. The two ends of the signal line 323 are electrically connected to the PCB sensing plate 322 and the central control panel respectively.
[0047] Specifically, a chip is also provided on the PCB sensing plate 322 . The PCB sensing plate 322 transmits the electrical signal to the chip for processing according to the detected capacitance change, and transmits the output signal to the central control panel through the signal line 323 .
[0048] Please combine Figure 6 , Figure 7 as well as Figure 8 As shown, in some embodiments, the end surface of the slider 321 away from the opening 11 is provided with a first cavity 321a, and the bottom wall of the first cavity 321a is fixedly provided with a first hollow column 321b arranged along the sliding direction of the slider 321, and the signal line 323 passes through the first hollow column 321b; the end surface of the mounting seat 31 close to the opening 11 is provided with a second cavity 311, and the bottom wall of the second cavity 311 is fixedly provided with a second hollow column 312 which is hollow and arranged along the sliding direction of the slider 321, the slider 321 is slidably connected with the inner wall of the second cavity 311, the first hollow column 321b slides with the inner wall of the second hollow column 312, and the compression spring ( Figure 6 , Figure 8 The second hollow column 312 is sleeved with a second hollow column 312.
[0049] Through the sliding connection between the slider 321 and the inner wall of the second cavity 311, and the sliding connection between the first hollow column 321b and the inner wall of the second hollow column 312, the sliding stability of the slider 321 after being squeezed can be increased, further improving the detection stability and accuracy of the present application.
[0050] Please refer to Figure 6 As shown, in some embodiments, a plurality of guide ribs 311a are circumferentially arranged on the inner wall of the second cavity 311 with the axis of the second hollow column 312 as the center, each guide rib 311a is axially arranged along the second hollow column 312, and each guide rib 311a is chamfered at one end close to the opening 11, and the slider 321 is slidably connected to each guide rib 311a.
[0051] By providing the guide rib 311a and the slider 321 to be slidably connected, the contact area between the mounting seat 31 and the slider 321 can be reduced, thereby reducing the friction resistance between the two, making the slider 321 slide more smoothly;
[0052] In addition, the chamfer of the guide rib 311 a can also play a certain guiding role in the installation of the slider 321 , thereby reducing the difficulty of installing the slider 321 .
[0053] Please combine Figure 7 as well as Figure 8 As shown, in some embodiments, a plurality of deformation grooves 321c are circumferentially opened at one end of the first hollow column 321b away from the opening 11 with its own axis as the center, and each deformation groove 321c is opened along the axis of the first hollow column 321b and penetrates the first hollow column 321b in the radial direction.
[0054] The deformation groove 321 c is provided so that the end of the first hollow column 321 b away from the opening 11 can be deformed radially inward under the action of external force, so as to facilitate the first hollow column 321 b to be inserted into the second hollow column 312 , further reducing the difficulty of installing the slider 321 .
[0055] Please combine Figure 7 as well as Figure 8 As shown, in some embodiments, a clamping portion 321d is fixedly provided at one end of the first hollow column 321b away from the opening 11, and the clamping portion 321d passes through the second hollow column 312; in the disengaged state, the clamping portion 321d is clamped against the end surface of the mounting base 31 away from the opening 11, and the PCB sensing plate 322 protrudes from the second cavity 311 toward the opening 11.
[0056] The clamping portion 321d can play a role of travel limit, thereby preventing the slider 321 from sliding too much toward the opening 11 and thus being separated from the mounting seat 31 .
[0057] Specifically, in the disengaged state, the compression spring is in a natural state or a partially compressed state.
[0058] Preferably, the outer edge of the clamping portion 321d is chamfered to reduce the difficulty of installation.
[0059] Please combine Figure 1 as well as Figure 5 As shown, in some embodiments, the mounting seat 31 and the oil cup bracket 10 are fixed by bolts.
[0060] Specifically, the bottom of the oil cup bracket 10 and the mounting seat 31 are provided with corresponding bolt holes.
[0061] A second aspect of the present application provides a cooking device, including a device body and the above-mentioned oil level detection structure, wherein an oil cup bracket 10 is arranged at the bottom of the device body.
[0062] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0063] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
