Description

Technical Field

[0001] This utility model relates to the field of rice cooker technology, and in particular to a micro-wind anti-backflow valve for rice cookers to prevent overflow. Background Technology

[0002] The check valve is a key component of the sealed structure of a rice cooker, which is crucial to the cooking effect and the taste of the rice. It is mostly installed inside the lid or at a specific position on the top of the rice cooker. It is usually a small round or square structure, which is small in size and does not take up too much space. The anti-overflow check valve works mainly based on the principle of air pressure difference. When cooking rice, the temperature inside the pot rises and the bubbles increase, making it easy for the pot to overflow. At this time, the miniature blower of the anti-overflow pot is activated. The miniature blower blows air into the pot through the check valve to prevent overflow. The miniature blower is activated when the anti-overflow pot is in use and is deactivated when steaming rice. Currently, some pneumatic check valves require relatively high air pressure, which cannot be opened by the force of a miniature blower. Therefore, existing check valves cannot meet the requirements. To address this issue, a miniature blower check valve for rice cookers is proposed to prevent overflow. Utility Model Content

[0003] To overcome the above deficiencies, this utility model provides a micro-wind check valve for preventing overflow in rice cookers, aiming to improve the problem that the micro blower in some rice cookers in the prior art cannot blow the valve open.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An anti-overflow valve for a rice cooker includes an air inlet and an air outlet. An anti-backflow mechanism is provided on the outside of the air inlet, a guide mechanism is provided on the outside of the air inlet, and a silicone tube is fixedly connected to the outside of the air outlet. The anti-reverse mechanism includes a fixed block, a cylindrical pin is fixedly connected inside the fixed block, an anti-reverse cover is rotatably connected to the outside of the cylindrical pin, a sealing ring is fixedly connected to the outside of the air inlet, the guide mechanism includes a fixed column, and a fixing component is provided on the outside of the air inlet. As a further description of the above technical solution: The fixing component includes a first locking pin, which is externally fixedly connected to the outside of the air inlet, and a second locking pin is externally fixedly connected to the outside of the air inlet. As a further description of the above technical solution: A spring is fixedly connected inside the fixed column, and a guide column is fixedly connected to the other end of the spring; As a further description of the above technical solution: An anti-slip pad is fixedly connected inside the air outlet, and the fixed column is fixedly connected to the inside of the air inlet. As a further description of the above technical solution: The fixing block is externally fixedly connected to the outside of the air inlet, and the sealing ring is made of silicone. As a further description of the above technical solution: The air inlet has grooves and a hole inside.

[0005] This utility model has the following beneficial effects: 1. In this utility model, the air outlet and the air inlet are connected by a square-shaped inclined groove. The check cover can rotate at a limited angle with the cylindrical pin as the center. When there is a slight breeze, it will open at the corresponding angle according to the wind force, allowing the air to pass through the check valve. When there is no wind, the check cover covers the air inlet with a 125-degree angle and its own weight (the thickness of the check cover can be adjusted to control its own weight, thereby adjusting the opening pressure of the slight breeze). When air pressure enters from the air outlet, it will apply reverse pressure to the check cover. The greater the pressure, the stronger the pressure on the sealing ring and the better the seal, thereby achieving backflow prevention.

[0006] 2. In this utility model, when installing the air inlet, to prevent deviation, first align the external guide post with the rice cooker mounting point. The spring generates elastic potential energy to squeeze the guide post, enhancing its fixation stability. Then, insert the first and second locking pins into the rice cooker mounting slot. The two are locked in the slot through the squeezing action, further improving the stability of the connection between the air inlet and the rice cooker, ensuring accurate and firm installation.

[0009] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0010] A type of anti-overflow valve for rice cookers, referring to... Figure 1 and Figure 2 It includes an air inlet 1 and an air outlet 2. The air inlet 1 is used to introduce gas, and the air outlet 2 is used to exhaust gas. An anti-reverse mechanism 3 is provided on the outside of the air inlet 1 to prevent gas from flowing back into the air inlet 1 from the air outlet 2. A guide mechanism 4 is provided on the outside of the air inlet 1 to fix and guide the air inlet 1. A silicone tube 6 is fixedly connected to the outside of the air outlet 2 to extend the air outlet path. Specifically, the air inlet 1 is used to introduce gas, and the air outlet 2 is used to exhaust gas. The air inlet 1 is equipped with a backflow prevention mechanism 3 to prevent gas from flowing back into the air inlet 1 from the air outlet 2. It is also equipped with a guide mechanism 4 to provide a fixed guide for the air inlet 1. The air outlet 2 is equipped with a silicone tube 6 to extend the air outlet path and ensure stable one-way gas flow. The anti-reverse mechanism 3 includes a fixing block 31, which provides mounting support for the cylindrical pin 32. The cylindrical pin 32 is fixedly connected inside the fixing block 31 and provides a rotation fulcrum. An anti-reverse cover 33 is rotatably connected to the outside of the cylindrical pin 32. The anti-reverse cover 33 opens and closes the air inlet 1 by rotation to prevent gas backflow. A sealing ring 34 is fixedly connected to the outside of the air inlet 1. The sealing ring 34 enhances the sealing performance when the anti-reverse cover 33 is closed. The fixing block 31 is fixedly connected to the outside of the air inlet 1. The air inlet 1 fixes the installation position of the fixing block 31. The sealing ring 34 is made of silicone, which gives it good elasticity and sealing performance. The guide mechanism 4 includes a fixing column 41, which provides a mounting base. A fixing component 44 is provided on the outside of the air inlet 1. The fixing component 44 is used to fix the position of the air inlet 1. Specifically, in the anti-backflow mechanism 3, the fixing block 31 is fixed outside the air inlet 1 to provide installation support for the internal cylindrical pin 32. The cylindrical pin 32 serves as a rotation fulcrum for the external anti-backflow cover 33 to rotate. The anti-backflow cover 33 can prevent gas backflow by opening and closing. The silicone sealing ring 34 outside the air inlet 1, with its good elasticity and sealing performance, can enhance the airtightness of the anti-backflow cover 33 when it is closed. The fixing column 41 of the guide mechanism 4 can provide a mounting base, while the fixing component 44 outside the air inlet 1 can further fix the position of the air inlet 1 and ensure the stability of the overall structure. The fixing component 44 includes a first locking pin 441, which is used to fix the air inlet 1. The external fixed connection of the first locking pin 441 is to the outside of the air inlet 1. The air inlet 1 provides an installation base for the first locking pin 441. The external fixed connection of the air inlet 1 includes a second locking pin 442, which assists the first locking pin 441 in enhancing the fixing effect. Specifically, the fixing component 44 includes a first locking pin 441 and a second locking pin 442, both of which are fixed to the outside of the air inlet 1. The first locking pin 441 is mainly used to fix the air inlet 1, which provides the installation base. The second locking pin 442 plays an auxiliary role, working with the first locking pin 441 to further enhance the fixing effect on the air inlet 1 and ensure the stable installation of the air inlet 1.

[0011] Reference Figure 3 and Figure 4 A spring 42 is fixedly connected inside the fixed column 41. The spring 42 generates elastic potential energy. A guide column 43 is fixedly connected to the other end of the spring 42. The guide column 43 guides the air inlet 1 to be fixed. The fixed column 41 is fixedly connected to the inside of the air inlet 1. The air inlet 1 fixes the installation position of the fixed column 41. An anti-slip pad 5 is fixedly connected inside the air outlet 2. The anti-slip pad 5 enhances the fit and sealing between the air outlet 2 and the air inlet 1. The air inlet 1 has grooves. The grooves increase the structural strength of the air inlet 1. The air inlet 1 has holes inside. The holes provide a channel for gas flow. Specifically, the fixing post 41 is fixed inside the air inlet 1, the internal spring 42 generates elastic potential energy, and the other end is connected to the guide post 43 to guide the air inlet 1 to be fixed. The anti-slip pad 5 inside the air outlet 2 enhances the fit and sealing with the air inlet 1. The grooves of the air inlet 1 increase the structural strength, and the internal holes allow gas to flow.

[0012] The implementation principle of this application embodiment is as follows: the air outlet 2 is connected to the air inlet 1 with a square 125-degree inclined groove. The check valve cover 33 can rotate within a limited angle with the cylindrical pin 32 as the center. When there is a breeze, it opens at different angles according to the wind strength, and the wind can pass through the check valve. When there is no wind, the check valve cover 33 covers the air inlet 1 with its own weight under the action of the 125-degree inclined angle. When air pressure enters from the air outlet 2, it will apply reverse pressure to the check valve cover 33. The greater the pressure, the greater the pressure of the check valve cover 33 on the sealing ring 34, and the better the seal will be, thus playing the role of preventing backflow. When installing the air inlet 1, to prevent installation deviation, align the guide post 43 on the outside of the air inlet 1 with the mounting point on the rice cooker. The spring 42 generates elastic potential energy to compress the guide post 43, making the guide post 43 more secure. Insert the first locking pin 441 and the second locking pin 442 into the mounting slot on the rice cooker. The first locking pin 441 and the second locking pin 442 are pressed and locked inside the mounting slot on the rice cooker, making the connection more secure.

[0013] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
