[0020] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-4 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0021] Please refer to Figures 1 to 4 The present application provides a check valve, which includes:

[0022] The valve body 1 is provided with a mounting groove 11 on the side wall of the valve body at the air outlet end;

[0023] The smoke pipe 2, part of which is located in the mounting groove 11. The smoke pipe 2 is connected to the valve body 1 through a limiting structure 3. When the smoke pipe 2 is connected to the mounting groove 11, the valve body 1 is connected to the smoke pipe 2. The limiting structure 3 is used to limit the relative position of the smoke pipe 2 and the valve body 1 after the smoke pipe 2 is installed to the valve body 1.

[0024] The telescopic mechanism 4 is arranged in the mounting groove 11;

[0025] The sealing ring 5 is disposed in the installation groove 11 , and the sealing ring 5 can at least abut against the inner wall of the installation groove 11 .

[0026] In one embodiment, the sealing ring 5 is embedded in the inner wall of the installation groove 11, and the sealing ring 5 is arranged to surround the smoke pipe 2. The telescopic mechanism 40 can help to quickly disassemble the smoke pipe 2 when it is separated from the valve body 1.

[0027] In another embodiment, the sealing ring 5 is arranged below the smoke pipe 2. Under the joint action of the limiting structure 3 and the telescopic mechanism 4, the compression force of the sealing ring 5 will not be too large to damage the sealing ring 5 or too small to cause insufficient sealing and cause oil smoke leakage. And the telescopic mechanism 40 can help to quickly disassemble the smoke pipe 2 when it is separated from the valve body 1.

[0028] The sealing ring 5 is preferably an O-ring.

[0029] In one embodiment, the telescopic mechanism 4 includes a spring 41, one end of which abuts against the bottom wall of the mounting groove 11, and the other end abuts against the sealing ring 5. The spring 41 can provide a stable buffer force, so that the force of compressing the sealing ring 5 will not be too large to damage the sealing ring 5 or too small to cause insufficient sealing and cause oil smoke leakage. The telescopic mechanism 40 can help to quickly disassemble the smoke pipe 2 when it is separated from the valve body 1. The spring 41 can be a reset spring.

[0030] In another embodiment, the telescopic mechanism 4 includes a spring 41 and a baffle 42. The end of the smoke pipe 2, the sealing ring 5, the baffle 42, and the return spring 41 are sequentially arranged in the mounting groove 11. One end of the spring 41 abuts against the bottom wall of the mounting groove 11, and the other end abuts against the baffle 42. One side of the baffle 42 can be connected to the spring 41, and the other side can be connected to the smoke pipe 2. Among them, the spring 41 can provide a stable buffering force, so that the force of the compression of the sealing ring 5 will not be too large to damage the sealing ring 5 or too small to cause insufficient sealing and cause oil smoke leakage. The setting of the baffle 42 is conducive to improving the stability of the telescopic mechanism 4 during the telescopic process. And the telescopic mechanism 40 can help to quickly disassemble when the smoke pipe 2 is detached from the valve body 1.

[0031] There is a gap between the blocking piece 42 and the inner wall of the installation groove 11 , so that the blocking piece 42 can slide smoothly in the installation groove 11 .

[0032] The limiting structure 3 includes a limiting block 31 provided on the smoke pipe 2 and a limiting groove 32 provided on the valve body 1. The limiting groove 32 includes a guide portion 321 and a limiting portion 322, wherein the guide portion 321 is formed by extending inwardly from the end surface of the air outlet end of the valve body 1, and the limiting portion 322 is connected to the guide portion 321. The limiting block 31 can enter and be positioned at the limiting portion 322 along the guide portion 321, so that the limiting structure 3 is used to limit the relative position of the smoke pipe 2 and the valve body 1 after the smoke pipe 2 is installed to the valve body 1. The installation process is as follows: the smoke pipe 2 is scratched to the bottom along the opening of the guide portion 321, and then the smoke pipe 2 is rotated so that the limiting block 31 is limited in the limiting portion 322.

[0033] The present application also provides a household appliance, which comprises the above-mentioned check valve.

[0034] The household appliance may be an integrated stove, a range hood, an integrated cooking center, etc.

[0035] The above are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Any feature disclosed in this specification (including the abstract and drawings), unless otherwise stated, can be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.
