[0006] The sealing device of the embodiment of the utility model has the following advantages: when liquid is taken into the liquid inlet, the valve plug opens the liquid inlet under the action of the liquid, so that the liquid can flow into the chamber; when the liquid inlet stops taking in liquid, the valve plug promptly blocks the liquid inlet under the action of its own gravity, so as to prevent the liquid at the liquid outlet from flowing back to the liquid inlet; the valve plug is limited by the limiting member, so as to prevent the valve plug from blocking the liquid outlet when the valve plug opens the liquid inlet, so that the liquid in the chamber can smoothly flow into the liquid outlet through the through hole; and the valve plug can be limited to move in a plane orthogonal to the first direction, so that the valve plug moves in the area adjacent to the liquid inlet in the plane, that is, the valve plug is not easy to move at will in the chamber, so as to improve the efficiency of the valve plug in blocking the liquid inlet and improve the sealing performance. Therefore, the sealing device of the embodiment of the utility model has good sealing effect and can prevent the liquid in the pipeline from flowing back.

[0008] The sealing device of the embodiment of the utility model can further limit the movement of the valve plug in a plane orthogonal to the first direction by changing the width of the accommodating space, that is, the valve plug only moves along the first direction, which further improves the efficiency of the valve plug in sealing the liquid inlet and improves the sealing performance. Moreover, by forming a transition space, when the liquid inlet stops taking in liquid, the liquid in the pipeline can flow back into the transition space through the liquid outlet, thereby reducing the liquid that flows back into the accommodating space and reducing the risk of liquid flowing back to the liquid inlet.

[0013] Optionally, the accommodating space is generally in an inverted V shape.

[0014] The sealing device of the embodiment of the utility model limits the accommodating space to an inverted V shape, so that the accommodating space can effectively limit the movement of the valve plug, and is easy to manufacture.

[0016] In the sealing device of the embodiment of the utility model, the through hole is set to be long and strip-shaped so that the valve plug is not easy to completely block the through hole, thereby ensuring that the liquid in the chamber can flow out through the through hole smoothly and strengthening the supporting force of the chamber.

[0017] Optionally, the through hole and the liquid inlet are arranged opposite to each other in the first direction, and the length of the through hole is the same as the diameter of the liquid inlet.

DETAILED DESCRIPTION

[0036] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0037] Please refer to the following Figures 1 to 10 A sealing device and a food processor according to an embodiment of the utility model are described.

[0038] like Figure 1-7 As shown, the sealing device 100 of the embodiment of the utility model includes a body 1, a valve plug 2 and a limiter 3. The body 1 has a liquid inlet 112, a chamber 13 and a liquid outlet 122 arranged along a first direction and connected in sequence. The valve plug 2 is arranged in the chamber 13, and the valve plug 2 can move under the action of liquid to block and open the liquid inlet 112. The limiter 3 is arranged in the chamber 13, and is used to block the valve plug 2 from blocking the liquid outlet 122 in the first direction, and limit the movement of the valve plug 2 in a plane orthogonal to the first direction. The limiter 3 has a through hole 35 for allowing liquid to flow through the limiter 3.

[0039] In the sealing device of the utility model embodiment, when liquid is introduced into the liquid inlet 112, the valve plug 2 opens the liquid inlet 112 under the action of the liquid, so that the liquid can flow into the chamber 13. When the liquid inlet 112 stops entering the liquid, the valve plug 2 timely blocks the liquid inlet 112 under the action of its own gravity to prevent the liquid at the liquid outlet 122 from flowing back to the liquid inlet 112. The valve plug 2 is limited by the limiter 3, so that the valve plug 2 can be prevented from blocking the liquid outlet 122 when the valve plug 2 opens the liquid inlet 112. 2, so that the liquid in the chamber 13 can smoothly flow into the liquid outlet 122 through the through hole 35, and can limit the movement of the valve plug 2 in a plane orthogonal to the first direction, so that the valve plug 2 moves in the area adjacent to the liquid inlet 112 in the plane, that is, the valve plug 2 is not easy to move arbitrarily in the chamber 13, so as to improve the efficiency of the valve plug 2 in blocking the liquid inlet 112 and improve the sealing performance. Therefore, the sealing device 100 of the embodiment of the utility model has a good sealing effect and can prevent the liquid in the pipeline from flowing back.

[0040] Alternatively, if Figure 4-6 As shown, the limit member 3 defines a accommodating space 41 in the chamber 13, which is open toward the liquid inlet 112 and connected with the liquid outlet 122 through the through hole 35. At least a part of the valve plug 2 is located in the accommodating space 41. In a cross section parallel to the first direction and orthogonal to the plane, the width of the accommodating space 41 in a second direction orthogonal to the first direction gradually decreases along the direction from the liquid inlet 112 toward the liquid outlet 122. The accommodating space 41 has limit surfaces opposite to each other in the second direction, and a part of the outer peripheral surface of the valve plug 2 is in contact with the limit surfaces.

[0041] Specifically, the width of the accommodating space 41 in the second direction orthogonal to the first direction gradually decreases along the direction from the liquid inlet 112 toward the liquid outlet 122, so that the degree of fit between the limiting surface of the accommodating space 41 and the valve plug 2 gradually increases along the direction from the liquid inlet 112 toward the liquid outlet 122, thereby gradually increasing the degree of extrusion of the limiting surface on the valve plug 2, and further making the valve plug 2 always fit the limiting member 3 during the movement along the first direction, and not easy to move randomly, that is, the valve plug 2 can only move along the first direction, further improving the efficiency of the valve plug 2 in blocking the liquid inlet 112 and improving the sealing performance. In addition, it is also made difficult for the valve plug 2 located in the accommodating space 41 to block the through hole 35, ensuring that the liquid in the accommodating space 41 can smoothly flow into the liquid outlet 122 through the through hole 35.

[0042] Optionally, the stopper 3 includes an annular base plate 31, an extension portion 32 and a stopper portion 33, the extension portion 32 extends from the annular base plate 31 toward the liquid inlet 112, the outer wall surface of the annular base plate 31 abuts against the inner wall surface of the chamber 13, and the inner wall surface of the annular base plate 31 is connected to the stopper portion 33. The stopper 3 has a first channel 34 extending along the first direction and passing through the annular base plate 31 and the extension portion 32, the stopper portion 33 is arranged in the first channel 34 to separate the first channel 34 into a transition space 42 communicating with the liquid outlet 122 and a receiving space 41 communicating with the liquid inlet 112, and the transition space 42 is communicated with the receiving space 41 through a through hole 35.

[0043] Specifically, the central axis of the liquid inlet 112 is colinear with the central axis of the first channel 34. The stopper 3 is installed in the chamber 13, and the accommodation space 41 is limited in the first channel 34 through the extension portion 32 and the stopper 33 is arranged in the first channel 34 of the extension portion 32, so that the size of the accommodation space 41 is reduced, and at least part of the valve plug 2 is located in the first channel 34, thereby limiting the range of movement of the valve plug 2 in a plane orthogonal to the first direction, so as to further limit the valve plug 2 in the plane orthogonal to the first direction, so that the valve plug 2 is not easy to move arbitrarily under the action of the liquid.

[0044] In addition, the structure of the limit member 3 is simple, and by forming a transition space 42, when the liquid inlet 112 stops taking in liquid, the liquid in the pipeline can flow back into the transition space 42 through the liquid outlet 122, thereby reducing the liquid that flows back into the accommodating space 41 and reducing the risk of liquid flowing back to the liquid inlet 112.

[0045] In other embodiments, Figure 6 As shown, the limiting member 3 may also only include the annular substrate 31 and the limiting portion 33. The limiting member 3 has a first channel 34 extending along the first direction and passing through the annular substrate 31. The limiting portion 33 is arranged in the first channel 34. The end of the valve plug 2 adjacent to the liquid outlet 122 is in contact with the limiting portion 33 to limit the valve plug 2.

[0046] Alternatively, if Figure 7As shown, the limiting portion 33 includes a first limiting portion 331 and a second limiting portion 332. The first limiting portion 331 extends obliquely from the periphery of the chamber 13 toward the center of the chamber 13, and the second limiting portion 332 extends obliquely from the periphery of the chamber 13 toward the center of the chamber 13. A through hole 35 is formed between the free end of the first limiting portion 331 and the free end of the second limiting portion 332. The limiting surface includes a first limiting surface 3311 and a second limiting surface 3321. The surface of the first limiting portion 331 facing the second limiting portion 332 constitutes the first limiting surface 3311, and the surface of the second limiting portion 332 facing the first limiting portion 331 constitutes the second limiting surface 3321, thereby making the limiting portion 33 simple in structure and effectively limiting the valve plug 2.

[0047] Specifically, one end of the first limiting portion 331 is connected to the inner wall surface of the first channel 34 adjacent to the liquid inlet 112, the other end of the first limiting portion 331 extends toward the liquid outlet 122 and is inclined toward the central axis of the first channel 34, and the side edge of one end of the first limiting portion 331 and the two side edges of the first limiting portion 331 in the second direction are connected to the inner wall surface of the first channel 34 and fit tightly.

[0048] One end of the second limiting portion 332 is connected to the inner wall surface of the first channel 34 adjacent to the liquid inlet 112, and the other end of the second limiting portion 332 extends toward the liquid outlet 122 and is inclined toward the central axis of the first channel 34. The side edge of one end of the second limiting portion 332 and the two side edges of the second limiting portion 332 in the second direction are connected to the inner wall surface of the first channel 34 and fit tightly, and the second limiting portion 332 is arranged opposite to the first limiting portion 331. The through hole 35 formed by the other end of the first limiting portion 331 (the free end of the first limiting portion 331) and the other end of the second limiting portion 332 (the free end of the second limiting portion 332) extends along the second direction.

[0049] The central axis of the valve plug 2 is colinear with the central axis of the first channel 34, so that the central axis of the valve plug 2 is colinear with the central axis of the through hole 35 in the second direction, so that when the valve plug 2 is in contact with the first limit surface 3311 and the second limit surface 3321, the valve plug 2 is located in the middle position of the first limit surface 3311 and the second limit surface 3321 in the second direction, that is, the valve plug 2 is located in the middle position of the accommodating space 41, so that there is a gap between the valve plug 2 and the peripheral wall of the accommodating space 41, and the valve plug 2 can block the middle position of the through hole 35 in the second direction without blocking the two end positions of the through hole 35 in the second direction. Therefore, when liquid is introduced into the liquid inlet 112, the liquid can flow into the liquid outlet 122 in turn through the gap between the valve plug 2 and the peripheral wall of the accommodating space 41 and the two end positions of the through hole 35 in the second direction.

[0050] Specifically, the through hole 35 is in the shape of an elongated strip, and the corners of the elongated through hole 35 are square, so that the cross-sectional area of ​​the through hole 35 is larger, and the valve plug 2 is not easy to completely block the through hole 35, so as to ensure that the liquid in the chamber 13 can flow out smoothly through the through hole 35, and can also strengthen the supporting force for the chamber 13.

[0051] Specifically, the through hole 35 and the liquid inlet 112 are arranged opposite to each other in the first direction and the length of the through hole 35 is the same as the diameter of the liquid inlet 112, so that the flow resistance of the liquid in the through hole 35 is relatively reduced, thereby reducing the pressure loss of the liquid and allowing the liquid to smoothly pass through the through hole 35. The liquid inlet 112 is circular and the through hole 35 is long and narrow, which can maintain the structural stability of the limiting portion 33, reduce the shape change of the limiting portion 33 due to the liquid pressure, and further reduce the problem of stress concentration or deformation of the limiting portion 33 due to the shape change.

[0052] Specifically, the material of the through hole 35 is silicone. When liquid is introduced into the liquid inlet 112, the liquid can open the free end of the first limiting portion 331 and the free end of the second limiting portion 332 to facilitate the liquid to flow through the through hole 35. When the liquid inlet 112 stops introducing liquid, the free end of the first limiting portion 331 and the free end of the second limiting portion 332 are closed, which can effectively prevent the liquid in the accommodating space 41 from flowing out through the through hole 35.

[0053] In other embodiments, the first limiting portion 331 and the second limiting portion 332 are arranged at intervals along the circumference of the first channel 34, so that a gap (not shown) is provided between the side of the first limiting portion 331 in the second direction and the side of the second limiting portion 332 in the second direction, and the gap is connected to the transition space 42 and the liquid outlet 122, so that the liquid in the accommodating space 41 can flow into the liquid outlet 122 through the through hole 35 and the gap at the same time, thereby improving the flow rate of the liquid flowing from the accommodating space 41 into the liquid outlet 122.

[0054] In other embodiments, one end of the first limiting portion 331 is connected to the inner wall surface of the first channel 34 adjacent to the liquid inlet 112, and the other end of the first limiting portion 331 extends toward the liquid outlet 122 and is inclined toward the second limiting portion 332, and / or, one end of the second limiting portion 332 is connected to the inner wall surface of the first channel 34 adjacent to the liquid inlet 112, and the other end of the second limiting portion 332 extends toward the liquid outlet 122 and is inclined toward the first limiting portion 331.

[0055] Optionally, the accommodating space 41 is substantially in an inverted V shape.

[0056] Specifically, Figure 7As shown, the cross-section of the accommodating space 41 in the direction orthogonal to the first direction and the second direction is generally in an inverted V shape. By limiting the accommodating space 41 to be inverted V shape, the limiting surface of the accommodating space 41 adjacent to the liquid outlet 122 can fit with the valve plug 2, thereby effectively limiting the movement of the valve plug 2, so that the valve plug 2 can only move along the first direction under the action of the liquid, and the accommodating space 41 is easy to manufacture. When the liquid inlet 112 stops supplying liquid, the valve plug 2 can also be guided to return to its original position.

[0057] In addition, the accommodating space 41 is generally inverted V-shaped, which makes it easy for a gap to be generated between the valve plug 2 and the first limiting portion 331 and the second limiting portion 332 in the second direction, and the gap is connected to the two ends of the through hole 35 in the second direction, so that the accommodating space 41 can limit the valve plug 2 while ensuring that liquid can flow from the accommodating space 41 into the liquid outlet 122.

[0058] Optionally, the chamber 13 includes a first chamber 131 and a second chamber 132 arranged along a first direction and connected to each other, the liquid outlet 122 is connected to the first chamber 131, the cross-sectional area of ​​the first chamber 131 is smaller than the cross-sectional area of ​​the second chamber 132, the annular substrate 31 is fitted in the second chamber 132, and the extension portion 32 is fitted in the first chamber 131, thereby improving the fit between the limit member 3 and the body 1 and improving the stability of the installation of the limit member 3 in the chamber 13.

[0059] In some embodiments, Figure 2 As shown, there are two first chambers 131, and the two first chambers 131 are arranged at intervals along the second direction. There are two second chambers 132, and the two second chambers 132 are arranged and connected along the second direction. There are two limit members 3, and the annular substrates 31 of the two limit members 3 are connected, and each annular substrate 31 corresponds to a second chamber 132. Specifically, the two annular substrates 31 can be formed as one piece. The extensions 32 of the two limit members 3 are arranged at intervals along the second direction, and correspond one to one with the two first chambers 131. There are also two valve plugs 2, and the two valve plugs 2 correspond one to one with the two limit members 3.

[0060] There are two liquid inlets 112 and two liquid outlets 122 on the body 1, one of the liquid inlets 112, one of the extensions 32 and one of the liquid outlets 122 is correspondingly arranged, and the other liquid inlet 112, the other extension 32 and the other liquid outlet 122 is correspondingly arranged, so that the body 1 can be filled with liquid through the two liquid inlets 112 at the same time. Therefore, the sealing device of the embodiment of the utility model can block the two liquid inlets 112 at the same time.

[0061] Alternatively, if Figure 2 As shown, the valve plug 2 includes a conical portion 21 and a spherical portion 22 connected to the bottom edge of the conical portion. The diameter of the spherical portion 22 is greater than the diameter of the liquid outlet 122 .

[0062] Specifically, the conical portion 21 of the valve plug 2 is suitable for fitting with the limiting surface, so that the valve plug 2 can easily move along the first direction under the action of the liquid, and the spherical portion 22 is arranged on the bottom surface of the conical portion 21, so that the center of gravity of the valve plug 2 is close to or located in the spherical portion 22, so that the valve plug 2 is not only not easy to tilt, but also suitable for cooperating with the liquid inlet 112, so that the spherical portion 22 is easy to block the liquid inlet 112. In addition, it can also play a buffering role when the valve plug 2 contacts the liquid inlet 112, avoiding the valve plug 2 and the liquid inlet 112 from hard collision. Moreover, the diameter of the spherical portion 22 is larger than the diameter of the liquid outlet 122, so that the valve plug 2 is not easy to leave the chamber 13 through the liquid outlet 122.

[0063] Specifically, the valve plug 2 is made of silicone, so that when the valve plug 2 is acted upon by liquid, the conical portion 21 of the valve plug 2 is easily squeezed with the limiting surface, thereby making the limiting portion 33 have a better limiting effect on the valve plug 2 .

[0064] Specifically, the valve plug 2 may be in the shape of a water drop. In other embodiments, the valve plug 2 may also be in the shape of a sphere or a rugby ball.

[0065] Alternatively, if Figure 2-3 As shown, the body 1 includes a first component 11 and a second component 12 that are detachably connected, so as to facilitate the installation of the valve plug 2 and the stopper 3, and to facilitate the replacement of the valve plug 2 and the stopper 3. The first component 11 has a liquid inlet channel 111, the inlet of the liquid inlet channel 111 forms a liquid inlet port 112, the chamber 13 is formed in the first component 11, and the second component 12 has a liquid outlet channel 121, the outlet of the liquid outlet channel 121 forms a liquid outlet port 122, and the liquid outlet channel 121 is connected to the chamber 13 through the liquid outlet port 122.

[0066] Specifically, the first component 11 has two liquid inlet channels 111, and the two liquid inlet channels 111 are arranged at intervals along the second direction, and the two liquid inlet channels 111 correspond one-to-one to the two first chambers 131.

[0072] In the food processor of the embodiment of the utility model, the processing cup 6 is placed on the main unit 7, and when liquid is injected into the processing cup 6 through the water tank 71, the valve plug 2 opens the liquid inlet 112 to facilitate the liquid in the water tank 71 to enter the processing cup 6, thereby facilitating the processing cup 6 to process food. When the water tank 71 stops injecting liquid into the processing cup 6, the valve plug 2 blocks the liquid inlet 112 to prevent the liquid in the processing cup 6 from flowing back to the water supply port 72. Therefore, the food processor of the embodiment of the utility model has a good sealing effect, which improves the user's operating experience.

[0073] In other embodiments, Figure 2 As shown, the sealing device 100 also includes a sealing member 5. There are two sealing members 5.
