Description

Technical Field

[0001] The utility model belongs to the field of daily necessities and relates to a splash-proof cover. Background Art

[0002] In daily life, a garbage collection device is set at the bottom of the sink to collect kitchen waste. A garbage disposer is often installed on the garbage collection device to break up solid kitchen waste. The broken solid kitchen waste is discharged from the pipe together with the liquid kitchen waste, thereby preventing the solid kitchen waste from clogging the pipe.

[0003] Chinese patent literature has disclosed a food waste disposer [application number: 00100005.5; publication number: 1257756A], which consists of a hopper, a crusher, a motor, and a connecting piece. The hopper assembly, a crushing box, a sewage elbow, and a driving motor are arranged in an upper and lower arrangement and connected in sequence to form the overall food waste disposer. The upper part of the hopper assembly is connected to the washing tank with a compression nut and a gasket. A funnel-shaped and openable splash guard is installed at the inlet. The upper and bottom parts of the hopper assembly are connected by a bevel bayonet device quick connector assembly, with a water leakage prevention ring and a dishwasher pipe inlet on the side. The structure of the splash guard results in poor splash protection effect, and liquid easily leaks out from the gaps between the bars. Technicians have improved the structure of the splash guard.

[0004] Chinese patent literature has disclosed a splash shield for a food waste disposer [application number: 201520601472.2; announcement number: 204875981U], comprising a shield body, a lower leakage opening is provided at the bottom center of the shield body, and a plurality of petal-shaped splash shields are provided at the bottom of the shield body, and the free ends of the splash shields extend downward and close to each other in an inclined shape with the central axis of the lower leakage opening as the center. The shield body and the splash shield are integrally formed and made of silicone material. A spacing opening is provided between each adjacent splash shield, and a spacing plate is provided above the spacing opening and the splash shield, and the lower leakage opening is located at the center of the spacing plate. When the garbage disposer is crushing food waste, the splash shield is in a closed state, which can prevent powdered food waste and liquid from flying out from the inlet during the crushing process. However, during the operation of the garbage disposer, a negative pressure state will appear inside the crushing box, that is, the air pressure inside the crushing box is less than the external atmospheric pressure. Since the splash shield is made of silicone material and has insufficient rigidity, the splash shield is easily sucked into the crushing box under the action of negative pressure, resulting in the failure of the splash shield's splash protection function. Summary of the invention

[0005] The utility model aims to solve the above problems in the prior art and proposes a splash guard, which solves the technical problem of how to improve the stability of the splash guard when installed in a garbage disposer.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A splash shield comprises a funnel-shaped shield body made of elastic material, a lower leakage opening is arranged at the center of the shield body, a shield wall of the shield body protrudes upward to form convex folds, there are several convex folds and they are distributed around the lower leakage opening, a concave fold is formed between two adjacent convex folds on the shield wall of the shield body, a fixing ring is arranged at the outer edge of the shield body, and it is characterized in that an annular groove is opened on the outer side surface of the fixing ring, and an annular support frame made of plastic or metal material is fixed in the annular groove.

[0008] During installation, the support frame is fixed against the inlet cavity wall. The support frame made of plastic or metal material has high structural strength, which can improve the structural stability of the fixing ring, thereby reducing the possibility of the splash guard being sucked into the crushing cavity by negative pressure, and improving the stability of the splash guard during installation in the garbage disposer.

[0009] In the above-mentioned splash guard, the upper end of the support frame has an upper protruding ring that protrudes upward from the fixing ring. The upper protruding ring can increase the structural strength of the support frame, reduce the possibility of the splash guard being sucked into the crushing chamber by negative pressure, and help improve the stability of the splash guard when installed in the garbage disposer.

[0010] In the above-mentioned splash shield, the lower side surface of the annular groove has a groove, and the lower end surface of the support frame has a protrusion, which is embedded in the groove and fixed. The arrangement of the protrusion and the groove increases the joint surface area between the support frame and the fixing ring, which is conducive to making the joint between the support frame and the fixing ring more tightly fixed, reducing the possibility of separation between the support frame and the fixing ring, and is conducive to improving the stability of the splash shield when installed in the garbage disposer.

[0011] In the above-mentioned splash shield, the outer side surface of the fixing ring is provided with a protruding lower convex ring below the supporting frame, and the lower end surface of the fixing ring is provided with a protruding bottom convex ring. The provision of the lower convex ring increases the radial thickness of the fixing ring, and the provision of the bottom convex ring increases the axial thickness of the fixing ring, thereby improving the structural strength of the lower end of the fixing ring, reducing the possibility of deformation of the fixing ring, and facilitating the stability of the splash shield when installed in the garbage disposer.

[0012] In the above-mentioned splash guard, the support frame and the fixing ring are integrally injection molded. The integral injection molding makes the joint between the support frame and the fixing ring more tightly fixed, reduces the possibility of separation of the support frame and the fixing ring, and is conducive to improving the stability of the splash guard when installed in the garbage disposer.

[0013] A splash shield comprises a funnel-shaped shield body made of elastic material, a lower leakage opening is arranged at the center of the shield body, a shield wall of the shield body protrudes upward to form convex folds, there are several convex folds and they are distributed around the lower leakage opening, a concave fold is formed between two adjacent convex folds on the shield wall of the shield body, a fixing ring is arranged at the outer edge of the shield body, and it is characterized in that a ring-shaped supporting frame made of plastic or metal material is embedded in the fixing ring, and the supporting frame is close to the outer side surface of the fixing ring.

[0014] During installation, the fixing ring of the splash guard is fixed against the cavity wall of the inlet. The supporting frame made of plastic or metal material has high structural strength, which can improve the structural stability of the fixing ring. Moreover, since the supporting frame is close to the outer side of the fixing ring, the distance between the supporting frame and the cavity wall of the inlet can be reduced, and the deformation amount of the elastic deformation of the outer side of the fixing ring is reduced, thereby reducing the possibility of the splash guard being sucked into the crushing cavity by negative pressure, and improving the stability of the splash guard during installation in the garbage disposer.

[0015] In the above-mentioned splash shield, the outer edge of the upper end surface of the fixing ring has a protruding upper convex ring, the supporting frame is arranged to be inclined outward from bottom to top, and the upper end of the supporting frame is close to or extends into the upper convex ring. In this way, the structural stability of the connection between the upper convex ring and the fixing ring can be improved, thereby reducing the possibility of the splash shield being sucked into the crushing chamber by negative pressure, and improving the stability of the splash shield when installed in the garbage disposer.

[0016] In the above-mentioned splash shield, the outer side surface of the fixing ring is provided with a protruding lower convex ring below the supporting frame, and the lower end surface of the fixing ring is provided with a protruding bottom convex ring. The provision of the lower convex ring increases the radial thickness of the fixing ring, and the provision of the bottom convex ring increases the axial thickness of the fixing ring, thereby improving the structural strength of the lower end of the fixing ring, which is conducive to reducing the possibility of deformation of the fixing ring and improving the stability of the splash shield when installed in the garbage disposer.

[0017] In the above-mentioned splash guard, the top surface of the convex fold is provided with a through vent hole, which allows air above and below the splash guard to circulate, reduces the formation of negative pressure, and is conducive to improving the stability of the splash guard when installed in the garbage disposer.

[0018] In the above-mentioned splash guard, the support frame and the fixing ring are integrally injection molded. The integral injection molding makes the joint between the support frame and the fixing ring more tightly fixed, reduces the possibility of separation of the support frame and the fixing ring, and is conducive to improving the stability of the splash guard when installed in the garbage disposer.

[0019] Compared with the prior art, the utility model has the following advantages:

[0020] A supporting frame made of plastic or metal material is fixed in the fixing ring of the splash guard, and the supporting frame is located at the outer side of the fixing ring, thereby improving the structural strength of the fixing ring and improving the stability of the splash guard when installed in the garbage disposer.
