[0035] like Figure 1-8 As shown, an electric pressure cooker with an easy-to-clean pressure relief valve includes,

[0036] The pot body 10 has an inner cavity with an upper opening, and an inner liner 101 is provided inside the inner cavity;

[0037] A lid 20 is installed at the upper opening to seal the inner cavity;

[0038] Pressure relief assembly 30; installed on the pot lid 20, the pressure relief assembly 30 includes a pressure relief pipe 301, a pressure relief cap 302 and an elastic retaining member 303, the pressure relief pipe 301 is installed on the top of the pot lid 20 and communicates with the inner cavity, the pressure relief cap 302 is sleeved on the end of the pressure relief pipe 301 away from the pot lid 20, and a sealing member 304 is provided on the inner top wall of the pressure relief cap 302 corresponding to the position of the pipe opening of the pressure relief pipe 301, the sealing member 304 is adapted to seal the pipe opening of the pressure relief pipe 301 under the action of external force;

[0039] The elastic retaining member 303 includes a sleeve 3031, an elastic member 3032, and a retaining block 3033. One end of the sleeve 3031 faces the pressure relief pipe 301 and is slidably connected to the pressure relief pipe 301. The other end faces the side wall of the pressure relief cap 302 and is fitted with the retaining block 3033. The elastic member 3032 is disposed inside the sleeve 3031. The side wall of the pressure relief cap 302 is provided with a retaining hole 3021 corresponding to the position of the retaining block 3033. The retaining block 3033 is adapted to move toward the retaining hole 3021 under the elastic force of the elastic member 3032 and partially pass through the retaining hole 3021.

[0040] The end of the card hole 3021 facing the inner side of the pressure relief cap 302 and / or the end of the retaining block 3033 near the side wall of the pressure relief cap 302 are provided with a chamfer;

[0041] The top of the pressure relief cap 302 is provided with a plurality of pressure relief holes 3022 evenly distributed.

[0042] When installing the pressure relief cap 302, the retaining block 3033 can be pressed to press it into the pressure relief cap 302. Then, the pressure relief cap 302 is moved down, and the retaining block 3033, under the elastic force of the elastic element 3032, abuts against the side wall of the pressure relief cap 302 until it moves to the position of the retaining hole 3021. At this time, the retaining block 3033 will partially protrude from the retaining hole 3021, thereby connecting the pressure relief cap 302 to the pressure relief pipe 301 and preventing the pressure relief cap 302 from falling off during use. When it is necessary to clean the pressure relief cap 302 and the pressure relief pipe 301, the user can press the retaining block 3033 to extend the portion of the retaining block 3033 extending out of the retaining hole 3021, so as to press the retaining block 3033 into the pressure relief cap 302. Then, the pressure relief cap 302 is lifted upward, and the retaining block 3033 will slide out of the retaining hole 3021 along the chamfer, so that the pressure relief cap 302 can be separated from the pressure relief pipe 301. The user can then clean the pressure relief cap 302 and the pressure relief pipe 301, improving the cleaning effect.

[0043] This utility model uses an elastic retaining member 303 to connect the pressure relief cap 302 and the pressure relief pipe 301, so as to prevent the pressure relief cap 302 from detaching under the action of high-pressure steam during use. In addition, the end of the retaining hole 3021 facing the inside of the pressure relief cap 302 or the chamfer of the retaining block 3033 allows the user to press the retaining block 3033 into the pressure relief cap 302, so as to achieve quick separation of the pressure relief cap 302 and the pressure relief pipe 301. This facilitates the user's cleaning of the pressure relief cap 302 and the pressure relief pipe 301 and improves the cleaning effect of the pressure relief cap 302 and the pressure relief pipe 301.

[0044] Preferably, to facilitate the sliding of the elastic retaining member 303 along the length of the pressure relief pipe 301, a groove 3011 is provided on the side wall of the pressure relief pipe 301 in this embodiment. The groove 3011 extends along the length of the pressure relief pipe 301, and the sleeve 3031 is slidably connected to the groove 3011 at one end facing the pressure relief pipe 301. In order to prevent the elastic retaining member 303 from disengaging from the groove 3011, a limiting block 3012 is also installed at the top of the groove 3011 in this embodiment to limit the elastic retaining member 303.

[0045] Furthermore, to ensure that the retaining block 3033 can engage with the retaining hole 3021 when installing the pressure relief cap 302, this embodiment also includes a guide assembly 40. The guide assembly 40 includes a guide rail 401 mounted on the side of the pressure relief pipe 301 and a guide block 402 mounted on the inner side of the pressure relief cap 302. The guide block 402 is slidably connected to the guide rail 401. When installing the pressure relief cap 302, the guide block 402 is first inserted into the guide rail 401 to restrict the rotation of the pressure relief cap 302, thereby allowing the retaining hole 3021 to engage with the pressure relief cap 302. With the retaining block 3033 in the same vertical plane, press down on the pressure relief cap 302 until the lower edge of the pressure relief cap 302 contacts the elastic retaining member 303. At this time, press the retaining block 3033 to press it into the sleeve 3031. The pressure relief cap 302 continues to move down, and the retaining block 3033 will abut against the inner wall of the pressure relief cap 302 under the elastic force of the elastic member 3032 until the retaining hole 3021 moves to the position of the retaining block 3033. The retaining block 3033 is then inserted into the retaining hole 3021 to complete the connection between the pressure relief cap 302 and the pressure relief pipe 301.

[0046] In order to prevent the sleeve 3031 from shaking when it moves along the slide groove 3011, in this embodiment, the guide assembly 40 further includes a guide sleeve 403 and a guide rod 404. The guide sleeve 403 is slidably disposed in the slide groove 3011 and located below the sleeve 3031. The top end of the guide sleeve 403 is fixedly connected to the sleeve 3031, and the bottom end of the guide sleeve 403 is sleeved outside the top end of the guide rod 404. The bottom end of the guide rod 404 is fixedly connected to the pot lid 20.

[0047] In this embodiment, a receiving groove 4041 is provided at the top of the guide rod 404. The pressure relief assembly 30 also includes a tension spring 305, which is disposed in the receiving groove 4041. One end of the tension spring 305 passes through the guide sleeve 403 and is fixedly connected to the sleeve 3031, while the other end is fixedly connected to the pot lid 20. This is suitable for providing elastic force to the elastic retaining member 303 to move towards the pot lid 20. The elastic member 3032 can provide elastic force to the sealing member 304 to seal the opening of the pressure relief pipe 301, and adjust the pressure relief according to the inner cavity during pressure relief. The pressure adaptability adjustment applies the elastic force to the sealing element 304, thereby controlling the distance between the sealing element 304 and the pipe opening to adjust the pressure relief rate, so that the pressure inside the cavity can be maintained within a certain range. In addition, a receiving groove 4041 for accommodating the tension spring 305 is opened on the guide rod 404, and the top end of the guide rod 404 is sleeved in the guide sleeve 403, which can form a sealed space, thereby isolating the receiving groove 4041 from the outside, thus preventing impurities mixed in the ejected fluid during the pressure relief process from contacting the tension spring 305, causing the tension spring 305 to rust or get stuck.

[0048] In addition, to prevent some of the fluid blocked by the pressure relief cap 302 from flowing along the surface of the pot lid 20 and affecting the cleanliness of the pot lid 20, a groove 201 is provided at the top of the pot lid 20 in this embodiment, and the pressure relief pipe 301 is installed at the bottom of the groove 201 so that the fluid blocked by the pressure relief cap 302 can flow into the groove 201 for collection. When cleaning, the user only needs to remove the pressure relief cap 302 and pour out the residue left in the groove 201.

[0049] To facilitate the sealing of the pressure relief pipe 301 opening by the sealing component 304, in this embodiment, a guide surface 3013 is provided at the edge of the opening of the pressure relief pipe 301, and an inclined surface adapted to the guide surface 3013 is provided on the sealing component 304. The sealing component 304 is made of elastic material. When the sealing component 304 contacts the pressure relief pipe 301, the inclined surface can slide along the inclined guide surface 3013 to enter the opening of the pressure relief pipe 301 and completely block the opening.

[0050] The above description provides a more detailed explanation of the present invention in conjunction with specific embodiments. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present invention.
