Abstract
Description
Technical Field
[0001] This utility model relates to the field of microwave oven technology, specifically a microwave oven protection device with an air frying function. Background Technology
[0002] Traditional microwave ovens primarily rely on preset times or power settings for heating, lacking the ability to directly monitor the state of food inside the cavity. Users typically need to adjust the heating time and power based on their experience and judgment. However, due to negligence or misoperation, users may sometimes forget to put food in the microwave or forget to turn it off after removing food, causing the microwave to operate unloaded.
[0003] Operating a microwave oven when it's unloaded poses a number of potential safety risks. First, the magnetron and other electronic components continue to operate even when unloaded, wasting energy and potentially accelerating wear and tear, thus shortening the oven's lifespan. Second, because the microwave oven cannot absorb microwave energy when unloaded, the microwaves will repeatedly reflect within the cavity, potentially causing overheating and leading to fires or other safety incidents. Utility Model Content
[0004] To address the aforementioned shortcomings, this invention proposes a microwave oven protection device with an air frying function. An air frying protection device is installed inside the microwave oven cavity, which can avoid the problem of traditional microwave ovens operating without load.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] A microwave oven protection device with air frying function includes a protective cover, a spring, a contact element, a positive lead terminal and a negative lead terminal, and a reset component;
[0007] Both the positive lead and the negative lead are mounted on the outside of the protective cover. The spring is rotatably mounted on the side of the protective cover away from the positive lead and the negative lead. The mounting part of the spring is located inside the protective cover, and the contact part of the spring is located on the outside of the protective cover. The mounting part is provided with the contact element.
[0008] In the initial state, the contact piece is not in contact with the positive and negative leads, and the circuit is broken. When an external force presses on the contact part of the spring, the mounting part of the spring causes the contact to move and gradually approach the positive and negative leads until the contact comes into contact with the positive and negative leads respectively, and the circuit is connected. At this time, the spring switches from the initial state to the displacement state.
[0009] The reset component is located on the mounting part. When the external force is removed, the reset component restores the spring piece from the displacement state to its original state.
[0010] The weight on one side of the mounting part is greater than the weight on the other side of the contact part. In the original state, due to gravity, one end of the mounting part droops down, causing the contact piece to not contact the positive and negative leads, thus breaking the circuit.
[0011] The reset assembly includes a reset spring, which is disposed on the upper surface of the mounting portion, and the top of the reset spring is fixedly connected to the top of the protective cover.
[0012] The reset assembly further includes a fixing pin and a fixing spring. The fixing pin is vertically disposed on the upper surface of the mounting part, and the fixing spring is sleeved on the fixing pin. The bottom of the fixing spring is fixedly connected to the mounting part, and the top of the fixing spring is fixedly connected to the contact element. The positive lead terminal includes a positive lead, a positive fixing nut, and a positive contact screw. The end of the positive contact screw is threaded through the protective cover and fixedly connected to the positive fixing nut. The end of the positive lead is fixedly connected to the positive fixing nut.
[0013] The negative lead terminal includes a negative lead, a negative fixing nut, and a negative contact screw. The end of the negative contact screw is threaded through the protective cover and fixedly connected to the negative fixing nut. The end of the negative lead is fixedly connected to the negative fixing nut.
[0014] The contact element abuts against the positive contact screw and the negative contact screw respectively.
[0015] The end of the abutment portion that is away from the mounting portion slopes downward.
[0016] The bottom of the protective cover has an arc surface, which abuts against the end of the abutting part near the mounting part.
[0017] The contact element is T-shaped, and the two reset springs are located on both sides of the contact element.
[0018] The technical solutions provided in this application embodiment may include the following beneficial effects:
[0019] 1. When the user gently presses the contact part of the spring with a container, the mounting part can tilt upwards. A contact element is installed on the mounting part, allowing the mounting part to move along with the contact element. At this time, the positive and negative leads are mounted on the top of the protective cover, and the contact element abuts against the positive and negative leads respectively. This contact connects the circuit through the contact element, allowing the air blast function to operate normally. When the user moves the container, separating it from the contact part, the mounting part moves downwards, causing the contact element to move away from the positive and negative leads, breaking the circuit and suspending the air blast function.
[0020] 2. When the vessel suddenly impacts the contact part, the contact part causes the mounting part to tilt upwards. At this time, the return spring can effectively absorb and disperse the upward tilting force of the mounting part, reducing the risk of damage to the electric shock component due to instantaneous impact, thereby protecting the safety and stability of the air explosion protection device in this solution.

[0030] The following is combined Figures 1 to 4 This invention describes a microwave oven protection device with an air frying function according to an embodiment of the present invention.
[0031] A microwave oven protection device with air frying function includes a protective cover 1, a spring 2, a contact element 3, a positive lead terminal 4, a negative lead terminal 5, and a reset component;
[0032] The positive lead 4 and the negative lead 5 are both installed on the outside of the protective cover 1. The spring 2 is rotatably installed on the side of the protective cover 1 away from the positive lead and the negative lead. The mounting part 21 of the spring 2 is located inside the protective cover 1, and the abutting part 22 of the spring 2 is located on the outside of the protective cover 1. The mounting part 21 is provided with the contact element 3.
[0033] In the original state, the contact piece 3 does not contact the positive lead end 4 and the negative lead end 5, and the circuit is broken. When an external force presses against the contact part 22 of the spring piece 2, the mounting part 21 of the spring piece 2 causes the contact piece 3 to tilt upward and contact the positive lead end 4 and the negative lead end 5 respectively, and the circuit is connected. At this time, the spring piece 2 switches from the original state to the displacement state.
[0034] The reset component is located on the mounting part 21. When the external force is removed, the reset component causes the spring piece 2 to return from the displacement state to the original state.
[0035] This invention provides a microwave oven protection device with an air-frying function, installed inside the microwave oven cavity. The spring clip 2 is rotated, allowing the mounting portion 21 to tilt upwards when the user lightly presses the contact portion 22 of the spring clip 2 with a utensil. A contact element 3 is mounted on the mounting portion 21, allowing the mounting portion 21 to move along with the contact element 3. At this time, the positive lead 4 and negative lead 5 are mounted on the top of the protective cover 1, and the contact element 3 abuts against the positive lead 4 and negative lead 5 respectively. This contact between the positive and negative leads 4 and 5 establishes a circuit through the contact element 3, enabling the air-frying function to operate normally.
[0036] When the user moves the vessel, the reset assembly can restore the spring 2 from the displaced state to its original state, and the mounting part 21 moves downward, causing the vessel to separate from the contact part 22, so that the contact 3 moves away from the positive lead end 4 and the negative lead end 5, the circuit is broken, and the air explosion function is suspended.
[0037] It is worth noting that the reset component is a component such as a spring or airbag that can deform and recover its original shape.
[0038] Therefore, an air blast protection device is installed inside the microwave oven cavity to avoid the problem of traditional microwave ovens running empty.
[0039] The weight on one side of the mounting part 21 is greater than the weight on the other side of the contact part 22. In the original state, due to gravity, one end of the mounting part 21 droops down, causing the contact piece 3 to not contact the positive lead end 4 and the negative lead end 5, thus breaking the circuit.
[0040] The reset assembly includes a reset spring 6, which is disposed on the upper surface of the mounting portion 21, and the top of the reset spring is fixedly connected to the top of the protective cover.
[0041] When the abutment part 22 loses its pressure, the compressed return spring 6 has good elastic deformation, stretches outward and presses down on the mounting part 21, so that the mounting part 21 can quickly return to its original position, thereby reducing the potential damage to the equipment caused by long-term power outages. Timely reset operation helps to maintain the good condition of the equipment and extend its service life.
[0042] Furthermore, when the vessel suddenly impacts the contact part 22, the contact part 22 causes the mounting part 21 to tilt upwards. At this time, the return spring 6 can effectively absorb and disperse the upward tilting force of the mounting part 21, reducing the risk of damage to the electric shock component 3 due to instantaneous impact, thereby protecting the safety and stability of the air explosion protection device of this solution.
[0043] The reset assembly also includes a fixing pin 23 and a fixing spring 24. The fixing pin 23 is vertically disposed on the upper surface of the mounting part 21. The fixing pin 23 is fitted with the fixing spring 24. The bottom of the fixing spring 24 is fixedly connected to the mounting part 21, and the top of the fixing spring 24 is fixedly connected to the contact element 3.
[0044] When the vessel suddenly hits the contact part 22, the contact part 22 causes the mounting part 21 to tilt upward. Without the buffering effect of the fixing spring 24, when the contact 3 comes into direct contact with the positive lead end 4 and the negative lead end 5, the contact 3 may be damaged or have poor contact due to the sudden strong impact.
[0045] Therefore, when the mounting part 21 tilts upwards, the fixing spring 24 acts as a buffer mechanism, effectively absorbing the impact force generated by the tilting. This buffering effect allows the contact element 3 to make contact with the positive lead 4 and the negative lead 5 in a relatively smooth and uniform manner, thereby greatly reducing the risk of damage to the contact element 3 due to sudden and strong impacts. At the same time, the smooth contact method also helps to ensure good contact between the contact element 3 and the positive and negative leads 5, ensuring stable current transmission.
[0046] When the mounting part 21 is reset, the fixing spring 24 can not only provide necessary support for the contact 3 when the mounting part 21 is reset, but also help the contact 3 to return to its original position smoothly through the elastic properties of the fixing spring 24.
[0047] In addition, the fixing pin 23 can play a limiting and guiding role, restricting the contact 3 to move only in a specific direction, preventing the contact 3 from shifting position and causing the contact 3 to be unable to connect with the positive lead 4 and the negative lead 5.
[0048] The positive lead terminal 4 includes a positive lead 41, a positive fixing nut 42, and a positive contact screw 43. The end of the positive contact screw 43 is threaded through the protective cover 1 and is fixedly connected to the positive fixing nut 42. The end of the positive lead 41 is fixedly connected to the positive fixing nut 42.
[0049] The negative lead end 5 includes a negative lead 51, a negative fixing nut 52, and a negative contact screw 53. The end of the negative contact screw 53 is threaded through the protective cover 1 and is fixedly connected to the negative fixing nut 52. The end of the negative lead 51 is fixedly connected to the negative fixing nut 52.
[0050] The contact element 3 abuts against the positive contact screw 43 and the negative contact screw 53 respectively.
[0051] The positive lead 41 and the negative lead 51 are used to transmit current, while the positive fixing nut 42 and the negative fixing nut 52 serve to fix and connect the electrodes. More importantly, the design of the positive contact screw 43 and the negative contact screw 53 not only serves as a bridge for current transmission, but also ensures a firm connection with the protective cover 1 through their threaded structure.
[0052] When contact element 3 comes into contact with the positive contact screw 43 and the negative contact screw 53 respectively, the circuit is instantly connected. This contact method ensures that the current can flow quickly and effectively from the positive to the negative terminal, meeting the device's immediate demand for electrical energy. At the same time, because the contact area between contact element 3 and the positive and negative contact screws 43 and 53 is large and the contact is tight, the contact resistance is greatly reduced, thereby reducing energy loss and improving energy utilization efficiency.
[0053] The end of the abutment portion 22 that is away from the mounting portion 21 is inclined downward.
[0054] When the vessel presses against the contact part 22, the contact part 22 flips downward under the pressure of the vessel, and at this time, the mounting part 21 tilts upward.
[0055] As the mounting section 21 rises, the contact element 3 mounted above the mounting section 21 also tilts upwards. When the mounting section 21 tilts to a certain angle, the contact element 3 will tightly abut against the positive contact screw 43 and the negative contact screw respectively, thereby realizing the connection of the circuit.
[0056] The bottom of the protective cover 1 is provided with an arc surface 11, which abuts against the end of the abutting part 22 near the mounting part 21.
[0057] Due to the close contact between the arc surface 11 and the contact part 22, the impact force or vibration generated during the placement of the vessel can be effectively dispersed and absorbed, thereby reducing the impact and damage to the internal structure of the equipment and improving the durability and reliability of the equipment.
[0058] The design of the arc surface 11 also makes the operation of the device more convenient and efficient. Because it can guide the abutment part 22 to flip, the user does not need to perform complicated operations or adjustments. Simply place the container on the guide rail and push it gently to connect the circuit, reducing the user's operating difficulty and labor intensity.
[0059] The contact element 3 is T-shaped, and the two reset springs 6 are located on both sides of the contact element 3.
[0060] The T-shaped contact element 3 extends in two vertical directions. The direction of the connection between the positive lead 4 and the negative lead 5 is perpendicular to the direction of the connection between the two fixing pins 23, which allows the mounting part 21 to install multiple components in a limited space, thereby making the whole structure more stable and reliable.
[0061] In addition, the T-shaped contact 3 can ensure stable contact with the positive and negative leads 5, guaranteeing the open and closed states of the circuit.
[0062] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
