toilet flushing mechanism

Abstract

This utility model discloses a toilet flushing structure, including a toilet body with a toilet seat ring mounted on it. The rear end of the toilet seat ring is hinged to the rear end of the toilet body. The main body is positioned on the upper edge of the toilet body. Several flushing heads are arranged in the toilet bowl, capable of horizontally flushing water along the surface of the toilet bowl. The water jets from each flushing head form a spiral water curtain in the toilet bowl, with the highest point of the spiral water curtain approaching or flush with the lower edge of the toilet seat ring. This utility model, through multiple flushing heads horizontally spraying water along the surface of the toilet bowl, and the highest point of the spiral water curtain extending to the lower edge or inner edge of the toilet seat ring, ensures that dirt from the top of the toilet bowl to the toilet seat ring area is directly flushed away, eliminating the cleaning dead zones in traditional structures and significantly reducing limescale residue.

Description

Technical Field

[0001] This utility model belongs to the technical field of water-saving toilets, and relates to the flushing structure of toilets. Background Technology

[0002] Traditional toilet flushing systems mainly rely on siphon or direct flush principles, using a water tank or instantaneous pressurization device to generate a unidirectional water flow to flush the surface of the toilet bowl. This results in problems such as rapid water pressure decay and insufficient uniform coverage, leading to high waste residue rates and significant water consumption.

[0003] Current technologies generally overlook the correlation between the cleanliness of the upper part of the toilet bowl and water conservation. Because the highest point of water flow in most flushing systems only reaches 1 / 2 to 2 / 3 of the toilet bowl's depth, the area from the top of the bowl to the bottom edge of the seat is often in a "dry flush" state, easily leading to stubborn limescale buildup. Users are often forced to increase flushing frequency or manually scrub, resulting in water waste and hygiene hazards.

[0004] Therefore, there is an urgent need to develop a new flushing structure: under the premise of ensuring low water consumption, by optimizing the water flow pattern and spatial distribution, to achieve full coverage and efficient cleaning of the toilet surface (especially the upper area), fundamentally breaking through the water utilization efficiency bottleneck of existing technologies. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the background art by proposing a toilet flushing structure.

[0006] To achieve the aforementioned technical objective, the technical solution adopted by this utility model is as follows:

[0007] A toilet flushing structure includes a toilet body with a toilet seat ring on it. The rear end of the toilet seat ring is hinged to the rear end of the toilet body. The main body is located on the upper edge of the toilet body. Several flush heads are provided in the toilet bowl of the toilet body. The flush heads can flush water horizontally along the surface of the toilet bowl. The water flow from each flush head forms a spiral water curtain in the toilet bowl. The highest point of the spiral water curtain is close to or flush with the lower edge of the toilet seat ring.

[0008] To optimize the aforementioned technical solution, the specific measures also include:

[0009] The inner and outer sides of the toilet seat extend downwards to form inner and outer guards, which make the longitudinal section of the toilet seat "∩" shaped. The inner and outer guards are located on the inner and outer sides of the upper edge of the toilet body, respectively.

[0010] The highest point of the aforementioned spiral water curtain contacts the inner edge of the toilet seat.

[0011] The aforementioned flush head is connected to an external water pipe, which can supply pressurized water to the flush head.

[0012] The number of flush heads mentioned above is four. These four flush heads are distributed in the front left, rear left, front right, and rear right of the toilet bowl. The nozzles of all flush heads are opened on the side of the flush head in a clockwise or counterclockwise direction.

[0013] All flush heads are at the same height in the toilet bowl.

[0014] A motor is fixedly installed at the rear end of the toilet body. The motor is connected to the toilet seat and can drive the toilet seat to rotate around the rear end of the toilet body.

[0015] A mounting bracket is fixed to the rear of the toilet body, and the motor is fixedly mounted on the mounting bracket.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model achieves highly efficient cleaning by covering the entire toilet bowl area. Multiple flush heads spray water horizontally along the surface of the bowl, creating a continuous and uniform spiral water curtain that completely overcomes the blind spots of traditional vertical water flow. The highest point of the spiral water curtain extends to the lower edge or inner rim of the toilet seat, ensuring that dirt from the top of the bowl to the toilet seat area is directly flushed away, eliminating cleaning dead zones in traditional structures and significantly reducing limescale residue.

[0018] 2. This utility model utilizes the centripetal adsorption effect generated by the rotating water flow of the spiral water curtain, which causes dirt to quickly flow into the drain along the spiral trajectory, reducing the ineffective diffusion of water flow; actual tests show that, under the premise of achieving the same level of cleanliness, this structure saves more than 30% of water compared with traditional toilets.

[0019] 3. The "∩" shaped design of the toilet seat of this utility model forms inner and outer protective edges, which can prevent the toilet seat from shaking back and forth and left and right after long-term use. The presence of the inner protective edge can also cover the upper part of the toilet bowl, thereby appropriately reducing the height of the spiral water curtain. Dirt on the inner protective edge can be cleaned separately by toilet seat cleaning equipment. Attached Figure Description

[0026] like Figure 1-3 As shown, the toilet flushing structure of this utility model includes: toilet body 1, toilet seat 2, 4 flush heads 3, mounting bracket 4, and motor 5.

[0027] The toilet body 1 is made of ceramic in one piece and the surface of the toilet bowl is a smooth glaze.

[0028] The toilet seat 2 is hinged to the upper rear end of the main body 1 via a stainless steel pivot, and can rotate 0°-120° around the pivot.

[0029] The inner and outer edge design of the toilet seat 2: the vertical height of the inner edge 21 is 10mm and the vertical height of the outer edge 22 is 10mm, so that the longitudinal section is “∩” shaped; when closed, the gap between the inner edge 21 and the inner wall of the toilet bowl is ≤5mm, and the outer edge 22 covers the outer edge of the upper edge of the main body 1.

[0030] Four stainless steel flush heads are embedded in the toilet bowl wall, with the center point 120mm from the bottom of the bowl (at the same height), and are symmetrically distributed on the left front, left rear, right front, and right rear.

[0031] Each flush head has a 1.2mm diameter nozzle on its three sides, with the nozzle axis at a 20° angle to the tangent of the toilet bowl wall, and all nozzles are uniformly deflected counterclockwise.

[0032] The flush head 3 is connected to an external booster pump via a PPR pipe, with a working pressure of 0.25 MPa. When the pump is working, the four flush heads 3 generate four streams of water that form a continuous spiral water curtain in the toilet bowl.

[0033] The highest point of the water curtain touches the lower edge of the inner edge 21 of the toilet seat 2.

[0034] Mounting bracket 4 is placed on the ground, and motor 5 is vertically fixed to mounting bracket 4 with screws; the output shaft of motor 5 is connected to the toilet seat rotating shaft through a coupling to realize electric rotation.

[0035] The working process of the toilet flushing structure of this utility model is as follows:

[0036] When the water pump is started, 0.25MPa water flows through the flushing head 3 and is sprayed horizontally; the four water streams rotate and overlap due to the tangential nozzles in the same direction, forming an upper spiral water curtain;

[0037] The upper end of the spiral water curtain is at the same height as the lower edge of the inner protective edge 21, and the dirt is drawn into the drain outlet by the centripetal water flow;

[0038] Stop rinsing after 5 seconds.
