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: CN00100005.5; publication number: CN1257756A], 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: CN201520601472.2; announcement number: CN204875981U], including a shield body, a lower leakage port 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 port as the center. The shield body and the splash shield are integrally formed and made of silicone material. A spacing port is provided between each adjacent splash shield, and a spacing plate is provided above the spacing port and the splash shield, and the lower leakage port 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 of 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 step is arranged on the convex fold, a fixing ring is arranged at the outer edge of the shield body, and it is characterized in that a protruding reinforcement part is arranged on the lower surface of at least one convex fold between the fixing ring and the step, and a vent hole penetrating the convex fold is arranged on the reinforcement part.

[0008] The vents allow the air above and below the cover to circulate, reducing the formation of negative pressure below the cover, and the reinforcement can increase the structural strength of the convex fold. Providing the vents on the reinforcement can reduce the collapse caused by insufficient strength of the cover due to the setting of the vents, thereby reducing the possibility of the splash guard being sucked into the crushing chamber by negative pressure, and improving the stability of the splash guard when installed in the garbage disposer.

[0009] In the above-mentioned splash guard, the two ends of the reinforcement part are respectively connected to the fixing ring and the step on the same convex fold, so that the structural strength of the reinforcement part can be further improved, the possibility of the splash guard being sucked into the crushing chamber by negative pressure can be reduced, and the stability of the splash guard installed in the garbage disposer can be improved.

[0010] In the above-mentioned splash guard, each convex fold is provided with a reinforcement part and a vent hole, which is conducive to balancing the air pressure above the cover body and the air pressure below the cover body, reducing the air pressure difference between the upper and lower parts of the cover body, and making the splash guard stably installed in the garbage disposer.

[0011] In the above-mentioned splash shield, on the same convex fold, the hole wall surface of the vent away from the step has a protruding upper baffle, and the hole wall surface of the vent close to the step has a protruding lower baffle, and the lower baffle is located below the upper baffle and there is a gap between the lower baffle and the upper baffle. In this way, staggered ventilation channels can be formed in the vent, and while the vent is used to prevent negative pressure from being generated to stabilize the installation of the splash shield, liquid or food debris can also be prevented from flying out of the vent when the garbage disposer is working, thereby ensuring the splash shield's splash-proof effect.

[0012] In the above-mentioned splash shield, on the same convex fold, the orthographic projection of the upper baffle on the lower baffle partially overlaps with the lower baffle, so that the upper end and the lower end of the vent hole can be completely staggered, further ensuring the splash-proof effect of the splash shield.

[0013] In the above-mentioned splash guard, on the same convex fold, the upper baffle is arranged to be tilted upwards on the side facing the step, and the lower baffle is arranged to be tilted downwards on the side facing away from the step. Such arrangement facilitates injection molding and demoulding of the splash guard, making the splash guard easy to mold.

[0014] 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, the 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 the characteristic is that a reinforcement part is arranged between the upper surface of at least one concave fold and the fixing ring, and the reinforcement part is arranged with a vent hole penetrating the concave fold.

[0015] The vents allow the air above and below the cover to circulate, reducing the formation of negative pressure below the cover, and the reinforced portion can increase the structural strength of the concave folds. Providing the vents on the reinforced portion can reduce the collapse caused by insufficient strength of the cover due to the setting of the vents, thereby reducing the possibility of the splash guard being sucked into the crushing chamber by negative pressure, and improving the stability of the splash guard when installed in the garbage disposer.

[0016] In the above-mentioned splash shield, each convex fold is provided with a step, and a protruding reinforcing rib is provided on the lower surface of each convex fold between the fixing ring and the step, and the two ends of the reinforcing rib are respectively connected to the fixing ring and the step in one piece.

[0017] The reinforcing ribs can increase the structural strength of the convex pleats, thereby reducing the possibility that the splash guard is sucked into the crushing chamber by negative pressure, and improving the stability of the splash guard when installed in the garbage disposer.

[0018] In the above-mentioned splash shield, the upper end of the vent hole is located on the side of the reinforcement portion facing the center of the shield body. This can reduce the liquid entering the vent hole to form an air film and affect the balance of air pressure above and below the shield body, which is conducive to reducing the possibility of the splash shield being sucked into the crushing chamber by negative pressure and improving the stability of the splash shield installed in the garbage disposer.

[0019] In the above-mentioned splash shield, each convex fold has a vertical wall near the center of the shield body, and a slit is provided on the vertical wall. A sealing film is provided to seal the lower leakage port, and an opening slit corresponding to and connected to the slit is provided on the sealing film to form a plurality of sealing flaps. When the water flows through the center of the shield body, the sealing flaps are separated from each other by the water pressure to open the lower leakage port, so that the water flows smoothly into the crushing chamber. When the water flows completely through, the sealing flaps are reset under the action of the elastic force of the shield body itself to re-close the lower leakage port, thereby enhancing the splash-proof effect of the splash shield.

[0020] Compared with the prior art, the utility model has the following advantages:

[0021] A reinforcement part is provided on the convex pleats or concave pleats, and a through vent hole is provided on the reinforcement part, which reduces the formation of negative pressure while ensuring the structural strength at the vent hole, thereby improving the stability of the splash guard in the garbage disposer. The upper port and the lower port of the vent hole are staggered, so that the vent hole is used for ventilation to improve the installation stability of the splash guard while ensuring the splash-proof effect of the splash guard.
