[0030] Embodiment one

[0031] Referring to Figures 1-6 As shown in the figure, the embodiment discloses an anti-insect structure, which is suitable for an electric appliance product with a coupler 2, and is especially suitable for an electric rice cooker.

[0032] The anti-insect structure of the embodiment comprises a base 1, a coupler 2 and a baffle 3; the coupler 2 is connected in the base 1, the base 1 is provided with a plug-in hole 11 opposite to the plug-in end of the coupler 2, the plug-in hole 11 is used for the plug-in of an external plug 8 to the coupler 2; the baffle 3 is arranged between the plug-in hole 11 and the coupler 2, and is slidingly connected to the base 1 to cover or open the plug-in hole 11.

[0033] Among them, the base 1 of the embodiment is used for mounting the coupler 2 and the baffle 3; the coupler 2 of the embodiment includes but is not limited to a power supply, a signal and a data coupler 2, the plug-in hole 11 is used for the plug-in of the plug 8 of an external wire to the coupler 2, so as to realize the connection of the internal circuit of the base 1 and the external wire. In specific implementation, the sliding baffle 3 makes the baffle 3 away from the plug-in hole 11, so that the plug-in hole 11 is opened, and the user can plug the external plug 8 into the coupler 2 through the plug-in hole 11, and when the plug-in state is ended, the sliding baffle 3 makes the baffle 3 close to the plug-in hole 11, so that the plug-in hole 11 is covered by the baffle 3, thereby avoiding the insects from entering the coupler 2.

[0034] The anti-insect structure of the embodiment, by setting the slidable baffle 3, makes the coupler 2 when not needed to be connected with the plug 8, the baffle 3 covers the plug-in hole 11, so as to form a physical barrier, effectively avoids the insects from contacting the plug-in end of the coupler 2, significantly reduces the risk of pollution caused by the oil stains, excrement and corpse of the insects to the coupler 2, thereby guarantees the cleanliness and safety of the coupler 2, effectively prevents the occurrence of safety hazards such as electric leakage and short circuit, and ensures the safety of the user's life and property; the user only needs to simply push the baffle 3 to make the baffle 3 slide, so as to easily cover or open the plug-in hole 11, thereby improving the practicability of the electric rice cooker and the user's satisfaction.

[0035] Specifically, the baffle 3 is provided with a push-blocking part 31, the push-blocking part 31 extends from the side of the baffle 3 close to the plug-in hole 11 to the plug-in hole 11. The push-blocking part 31 facilitates the user to push the baffle 3, so that the baffle 3 can slide in the base 1, thereby improving the moving convenience of the baffle 3, and further improving the user's experience.

[0036] Specifically, the push portion 31 is extended by the baffle 3 to the side of the insertion hole 11 away from the baffle 3. The push portion 31 protrudes out of the base 1 through the insertion hole 11, so as to be contacted by a hand or the plug 8, further reducing the difficulty of the user pushing the baffle 3. In addition, the push portion protrudes out of the insertion hole 11, and can form a limiting structure with the insertion hole 11 to limit the movement range of the baffle 3. More specifically, when the baffle 3 moves away from the insertion hole 11 until the push portion 31 abuts against the inner side wall of the insertion hole 11, the baffle 3 stops moving, avoiding the baffle 3 from being difficult to reset after being separated from the insertion hole 11. When ending the plug 8 and the coupler 2 in the insertion state, the push portion 31 at the edge of the insertion hole 11 can be moved to the direction of covering the insertion hole 11, significantly reducing the operation difficulty of the baffle 3.

[0037] Specifically, the push portion 31 is provided with an inclined surface 311, which is inclined by the baffle 3 to the side of the insertion hole 11 away from the baffle 3 and the direction away from the baffle 3. The inclined surface 311 has a guiding property. When the plug 8 or the user's finger contacts the inclined surface 311, an acting force is applied to the inclined surface 311, so that the push portion 31 slides along the inclined direction of the inclined surface 311, thereby pushing the baffle 3 to move. This reduces the resistance that the user needs to overcome when operating, and improves the convenience and efficiency of the baffle 3 moving.

[0038] In specific implementation, the user can not need to slide the baffle 3 with the finger, but only need to press the push portion 31 with the plug 8 and move the plug 8 to the end of the baffle 3 away from the inclined surface 311, so that the baffle 3 moves away from the insertion hole 11. Continuing to push the plug 8 can push the plug 8 into the insertion hole 11, and then into the insertion end of the coupler 2. This simplifies the steps of sliding the baffle 3 and inserting the plug 8, improves the insertion efficiency of the plug 8, and further improves the user's satisfaction.

[0039] It can be understood that in other embodiments, an arc surface can be used instead of the inclined surface 311 according to actual needs. The arc surface has a guiding property, provides a smooth contact for the plug 8, can reduce the wear of the plug 8, and improves the durability of the electrical product.

[0040] Specifically, the base 1 is provided with a sliding rail 12, and the extending direction of the sliding rail 12 is perpendicular to the plugging direction of the plug 8; the baffle 3 is slidingly connected to the sliding rail 12. The sliding rail 12 provides a clear sliding path for the baffle 3, and can prevent the baffle 3 from deviating or shaking during the sliding process of the baffle 3, thereby ensuring that the baffle 3 can accurately cover the plugging hole 11; the provision of the sliding rail 12 helps to reduce the friction between the baffle 3 and the base 1 during the sliding process, which not only can reduce the resistance of the baffle 3 during sliding and improve the smoothness of the movement of the baffle 3, but also can reduce the wear of the baffle 3 and the base 1 and prolong the service life of the product. Since the extending direction of the sliding rail 12 is perpendicular to the plugging direction of the plug 8, it is ensured that the baffle 3 will not block the plug 8 from plugging the coupler 2 when the baffle 3 is away from the plugging hole 11 to open the plugging hole 11, avoiding the mutual interference of the sliding of the baffle 3 and the plugging of the plug 8, and also enabling the baffle 3 to completely cover the plugging hole 11 when the coupler 2 is not in use.

[0041] In the present embodiment, the sliding rail 12 is horizontally arranged, one end of the sliding rail 12 is arranged between the coupler 2 and the plugging hole 11, and the other end extends away from the coupler 2. The horizontal arrangement of the sliding rail 12 enables the baffle 3 to move horizontally, and reduces the influence of the gravity of the baffle 3 on the movement of the baffle 3, significantly reduces the movement resistance of the baffle 3, improves the movement efficiency of the baffle 3, and at the same time, compared with vertical movement, does not need to be provided with a sinking prevention structure, greatly simplifies the arrangement of the insect prevention structure, has a simple structure and is convenient to maintain, reduces the production and maintenance cost of the insect prevention structure, and realizes the dual optimization of economy and practicability of the insect prevention structure.

[0042] It can be understood that in other embodiments, the sliding rail 12 can be arranged obliquely or vertically to enable the baffle 3 to move obliquely or vertically to open and close the plugging hole 11.

[0043] Specifically, the sliding rail 12 is provided with a sliding groove 121, and the sliding groove 121 is arranged along the length direction of the sliding rail 12; one end of the baffle 3 close to the sliding rail 12 is provided with a connecting column 32, and the connecting column 32 penetrates the sliding rail 12. The baffle 3 is slidingly connected with the sliding groove 121 through the connecting column 32, the sliding groove 121 provides a clear sliding path for the connecting column 32, and ensures that the connecting column 32 and the baffle 3 will not deviate from the sliding rail 12 during the movement; and the connecting column 32 penetrates the sliding groove 121, and the sliding groove 121 can limit the swinging of the connecting column 32 to prevent the baffle 3 from shaking or deviating during the sliding process.

[0044] Specifically, the groove width of the sliding groove 121 is less than or equal to the thickness of the baffle 3. In the closed state of the plugging hole 11, the thickness of the baffle 3 is greater than or equal to the groove width of the sliding groove 121, which can increase the airtightness of the connection between the baffle 3 and the plugging hole 11, further increase the insect prevention effect of the insect prevention structure, and avoid that the sliding groove 121 is too wide to cause a large gap between the baffle 3 and the plugging hole 11 to provide activity space for insects to enter the coupler 2.

[0045] Specifically, the elastic reset member 4 is arranged between the end of the slide rail 12 away from the insertion hole 11 and the baffle 3. The elastic reset member 4 is used to move the baffle 3 to restore the baffle 3 to the state of covering the insertion hole 11. When the baffle 3 gradually moves away from the insertion hole 11, the baffle 3 pushes the elastic reset member 4, so that the elastic reset member 4 is compressed until the insertion hole 11 is open, the plug 8 enters the insertion hole 11 and completes the insertion with the coupler 2, so that the baffle 3 is abutted by the plug 8, at this time the elastic reset member 4 stores elastic potential energy and maintains the maximum compression state; when the plug 8 is pulled out, the baffle 3 is not abutted, and the elastic reset member 4 pushes the baffle 3 to be close to the insertion hole 11 under the action of releasing its elasticity until the baffle 3 completely covers the insertion hole 11. The elastic reset member 4 provides an automatic reset function for the baffle 3, ensures the persistence of the anti-insect effect of the anti-insect structure, and improves the user's convenience.

[0046] It can be understood that in other embodiments, the end of the elastic reset member 4 away from the baffle 3 can be abutted against the base 1 according to actual needs. The base 1 is used to support, protect and support the internal structure of the electrical product, so that the electrical product can be stably placed on a plane and has high stability, and the elastic reset member 4 is arranged between the inner side wall of the base 1 and the baffle 3, which can also ensure that the baffle 3 is given sufficient power by the elastic reset member 4 to ensure that the baffle 3 can be reset smoothly.

[0047] In the embodiment, the elastic reset member 4 is a compression spring. The compression spring has high elasticity and adaptability, can provide sufficient thrust for the baffle 3, has good durability, improves the structural stability of the anti-insect structure, and prolongs the service life of the anti-insect structure. In addition, the compression spring is economical and practical, easy to maintain and replace, and helps to reduce the production and maintenance cost of the anti-insect structure.

[0048] It can be understood that in other embodiments, a spring sheet, an elastic rubber block or other elastic reset members 4 can be used to replace the compression spring according to actual needs.

[0049] Specifically, the insect prevention structure of the embodiment further comprises a position detector 5. The position detector 5 is arranged at one end of the slide rail 12 away from the plug-in hole 11, and is used to detect the position signal of the baffle 3. The position detector 5 can detect in real time whether the baffle 3 is in the correct position, i.e., whether the plug-in hole 11 is completely open. When the baffle 3 is away from the plug-in hole 11 until it contacts the position detector 5, the plug-in hole 11 is completely open. At this time, the position detector 5 sends a baffle 3 position signal, so as to monitor and control the state of the electrical product, improve the intelligent degree of the product, and help to improve the market competitiveness of the product. In addition, when the user operates improperly or the structure is aged, causing the baffle 3 to fail to reset correctly, the position detector 5 can send a fault alarm or prompt, so as to troubleshoot or repair the insect prevention structure in time, avoid the plug-in hole 11 still being open after the plug 8 is decoupled from the coupler 2, and make insects enter the plug-in end of the coupler 2, thereby further ensuring the insect prevention effect and persistence of the insect prevention structure, and helping to improve the trust and satisfaction of users to the product.

[0050] Specifically, the position detector 5 is a micro switch. The micro switch has a small contact interval and a fast action mechanism, so that the action stroke of the micro switch is short, the pressing force is small, the on-off is rapid, and therefore the response speed is very fast. When the baffle 3 is contacted, the micro switch can quickly send a signal, and high-precision baffle 3 position detection can be realized. The contact interval of the micro switch is small, the arc light duration generated during action is short, and the contact damage is small, so the service life is relatively long. When the micro switch is used as the position detector 5, it can operate stably for a long time, reducing maintenance costs. In addition, the micro switch has small size and light weight, and is relatively simple to install and debug, thereby improving the space utilization rate in the base 1 and reducing the production cost of the insect prevention structure.

[0051] It can be understood that in other embodiments, a proximity sensor, a photoelectric sensor, or the like can be used as the position detector 5 to replace the micro switch according to actual needs. More specifically, the proximity sensor can judge the position of the baffle 3 by detecting the distance between the baffle 3 and the sensor; and the photoelectric sensor can calculate the distance between the baffle 3 and the position detector 5 by calculating the time of light emission and light reception.

[0052] Specifically, the base 1 is further provided with a heat dissipation hole 13, and the heat dissipation hole 13 is provided with a filter screen. The heat dissipation hole 13 can dissipate heat inside the base 1 to the outside, so as to prevent the electrical product from being damaged due to overheating of internal components during use. The setting of the filter screen improves the insect prevention performance of the insect prevention structure and the corresponding product without affecting the heat dissipation effect, so as to prevent external dust, insects and other impurities from entering the inside of the base 1 through the heat dissipation hole 13, thereby keeping the inside of the base 1 clean and the electrical product running normally.

[0053] Specifically, the heat dissipation hole 13 is further provided with a hole cover 6, which is fixedly connected to the baffle 3; when the baffle 3 covers or opens the plug-in hole 11, the hole cover 6 covers or opens the heat dissipation hole 13. The hole cover 6 can further protect the safety of the electrical product. When the hole cover 6 covers the heat dissipation hole 13, it can prevent external impurities such as fine dust, tiny insects, etc. from entering the inside of the base 1 through the filter screen, thereby ensuring the normal operation of the electrical product. The hole cover 6 can also prevent water or other liquids from entering the base 1 to some extent, improve the waterproof performance of the electrical product, and further protect its safety and service life. In addition, the hole cover 6 moves with the baffle 3, so that when the coupler 2 is connected with the external power cord, i.e. when the electrical product is running, the heat dissipation hole 13 can be quickly opened, improving the heat dissipation efficiency of the electrical product. The hole cover 6 and the baffle 3 can also cover or open the heat dissipation hole 13 and the plug-in hole 11 synchronously, simplifying the user's operation steps and improving the convenience of using the electrical product.

[0054] Specifically, the plug-in hole 11 is arranged on the side surface of the base 1, and the heat dissipation hole 13 is arranged on the bottom surface of the base 1. The plug-in hole 11 and the heat dissipation hole 13 can be arranged at different positions of the base 1 respectively, avoiding mutual interference, and also making the internal structure of the base 1 more compact and reasonable, and improving the space utilization rate. The heat generated inside the base 1 can be directly transmitted to the external environment through the heat dissipation hole 13. The bottom surface of the base 1 usually has a larger contact area with the external environment, and the temperature of the external environment is relatively low, so a larger temperature difference can be formed. This temperature difference will drive air flow and form natural convection, thereby accelerating heat dissipation. The heat dissipation through natural convection effect does not require an external power source, has the advantages of energy saving and low noise, and the heat dissipation hole 13 arranged on the bottom surface of the base 1 is beneficial to the arrangement of the heating element in a perpendicular and parallel manner, which can accelerate heat dissipation and further improve the heat dissipation efficiency of the electrical product. The plug-in hole 11 arranged on the side surface of the base 1 is also convenient for the user to perform the plug-in operation of the plug 8 and the coupler 2, without the need to turn over the base 1, thereby improving the convenience of using the electrical product.

[0055] It can be understood that in other embodiments, the positions of the plug-in hole 11 and the heat dissipation hole 13 can be adjusted according to actual needs. For example, the plug-in hole 11 can be arranged on the bottom surface of the base 1, and the heat dissipation hole 13 can be arranged on the side surface of the base 1.

[0056] Specifically, the baffle 3 moves horizontally along the inner side where the plug-in hole 11 is located, and the moving direction of the hole cover 6 is consistent with that of the baffle 3. The baffle 3 and the hole cover 6 move in the horizontal direction, which reduces the influence of gravity of the baffle 3 and the hole cover 6 on the movement of the baffle 3 and the hole cover 6, significantly reduces the moving resistance of the baffle 3 and the hole cover 6, improves the moving efficiency of the baffle 3 and the hole cover 6, and does not need to set a sinking prevention structure, greatly simplifies the setting of the insect prevention structure, and does not occupy additional vertical space, thereby saving operation space and avoiding interference with other elements. Since the moving direction of the baffle 3 and the hole cover 6 is consistent, the user can operate more intuitively and conveniently when controlling the movement of the baffle 3 and the hole cover 6, thereby improving the user experience.

[0057] Specifically, the insect prevention structure of the embodiment further includes a connecting rod 7, and two ends of the connecting rod 7 are respectively connected to the outer side of the baffle 3 and the hole cover 6. The baffle 3 drives the connecting rod 7 to move, and in turn drives the hole cover 6 to move. The connecting rod 7 ensures that the baffle 3 and the hole cover 6 can move synchronously, thereby realizing synchronous opening and closing operations of the plug-in hole 11 and the heat dissipation hole 13. In addition, the connecting rod 7 has the characteristics of simple structure, stability and reliability, can reduce the failure rate, improve the durability of the insect prevention structure, improve the overall quality of the product, and is convenient to install and debug, thereby reducing the production cost.

[0058] In the embodiment, one end of the connecting rod 7 is fixedly connected to the side of the baffle 3 away from the plug-in hole 11 and the coupler 2. The connecting rod 7 is located between the coupler 2 and the in-place detector 5, does not interfere with the plug-in of the plug 8 in the open state of the plug-in hole 11, and does not interfere with the movement of the baffle 3, thereby avoiding the blockage of the coupler 2 to make it difficult for the hole cover 6 to move.

[0059] It can be understood that, in other embodiments, one end of the connecting rod 7 can be fixedly connected to the top surface of the baffle 3, and the connecting rod 7 is arranged in a bent manner; or one end of the connecting rod 7 can be fixedly connected to the bottom surface of the baffle 3. When the baffle 3 moves horizontally, the hole cover 6 moves horizontally with the baffle 3, so that the hole cover 6 moves away from above the heat dissipation hole 13, thereby facilitating the heat in the base 1 to dissipate to the outside of the base 1 through the heat dissipation hole 13.

[0060] Specifically, the coupler 2 is provided with a mounting portion (not shown) arranged at the top, bottom, side away from the position detector 5 or side away from the plug-in hole 11 of the coupler 2 and connected to the base 1. Further, the connecting portion is arranged away from the opening direction of the baffle 3. The coupler 2 is fixedly connected to the base 1 through the mounting portion, which can be arranged at the top or bottom of the coupler 2, i.e., the top or bottom of the coupler 2 is connected to the base 1, or arranged at the side away from the position detector 5 of the coupler 2, i.e., the side of the coupler 2 is connected to the base 1, or arranged at the side away from the plug-in hole 11 of the coupler 2, i.e., the back of the coupler 2 is connected to the base 1. The mounting position is flexible and can adapt to the sliding arrangement of the baffle 3.

[0061] Specifically, the insect prevention structure of the embodiment further comprises an electric control board (not shown) arranged in the base 1 and electrically connected to the position detector 5. When the baffle 3 physically contacts the position detector 5 during movement, the position detector 5 will immediately capture the signal and convert it into an electrical signal, i.e., a baffle 3 in-place signal, and rapidly send the baffle 3 in-place signal to the electric control board to record, manage and control the state of the baffle 3. This helps the electric control board to obtain power-on information in advance before the coupler 2 is formally powered on, so as to control the elements in the base 1 to perform preprocessing operations, such as adjusting the working state of the elements, preheating key components, checking and optimizing circuit connections, etc., to ensure that the key elements in the base 1 can quickly enter the best working state after the coupler 2 is powered on, thereby effectively improving the overall performance and working efficiency of the electric appliance product. The arrangement of the electric control board improves the intelligence of the insect prevention structure and brings a good user experience, thereby increasing the market competitiveness of the electric appliance product.

Through physical isolation of the baffle 3, the chances of insects and their excrement, carcasses and other pollutants entering the inside of the electric rice cooker are reduced, which helps to maintain the hygiene of the inside of the base 1 and the food in the electric rice cooker and improves the cleanliness and safety of the electric rice cooker. In addition, users do not need to worry about the failure of the electric rice cooker caused by insects, which reduces the frequency of maintenance and replacement of the electric rice cooker and improves the satisfaction and reliability during use.

[0065] The coupler 2 of the embodiment is a power coupler, and the plug 8 is connected to the power coupler. External wires are connected to the power socket and the power coupler to realize power supply of the electric rice cooker and provide power guarantee for normal operation of the electric rice cooker.
