Description

Toilet seat

Technical field

The invention relates to the field of sanitary ware, and in particular to a toilet seat.

Background technique

The toilet is a sanitary ware that modern people have to touch every day. As people's quality of life improves, the hygiene requirements for the toilet are getting higher and higher. The initial toilet has only a defecation flushing function, that is, the water in the water tank directly rushes directly into the drain inlet of the drain pipe through the water outlet of the toilet seat, but the inner wall of the toilet seat cannot be automatically cleaned. Due to the fact that some of the faeces on the inner wall of the toilet seat will stick to the upper surface during defecation, these excretions can only be cleaned by hand.

In view of this problem, those skilled in the art have invented a toilet having an inner wall function of automatically cleaning the toilet seat as shown in Patent No. 200320100838.5 (Fig. 5). The upper edge of the inner wall of the toilet seat is provided with a water passage, and the water enters from the water tank. The water passage is passed, and then flows out from the washing water outlet to achieve the function of automatically cleaning the inner wall of the toilet seat. However, in the case of long-term use, the lower edge of the washing water hole is prone to water marks and is not easy to clean; when there is no water, the water passage is easy to hide dirt, for example, insects such as cockroaches and cockroaches can be washed from the water. The water hole climbed in, which was both scary and unsanitary. Moreover, because of the aesthetic appearance, the washing water outlet is generally hidden inside the water passage, which makes it easier to clean. Summary of the invention

The toilet seat of the embodiment, as shown in FIG. 1, includes a water tank 1, a water pipe 6, a water storage chamber 4, and a water retaining plate 5; the water tank 1 (Fig. 6) is disposed around the inner wall of the toilet seat The upper part of the water tank 1 is connected to the water outlet 2; the water inlet 2 of the water pipe 6 is disposed at the rear of the toilet seat and communicates with the water tank; a nozzle 3 facing the inner wall 7 of the toilet seat; a water storage chamber 4 disposed between the water outlet 3 of the water conduit 6 and the water inlet 2 of the water conduit 6 , the water inlet 2 The water passing capacity is greater than the water outlet 3; the upper portion of the toilet seat is provided with the water retaining plate 5 covering the water outlet 3, and the left and right ends of the water blocking plate 5 are spaced from the water drain 5 There is a gap, a lower end of the water deflector 5 is spaced apart from the inner wall 7 of the toilet seat; the water deflector 5, as shown in FIG. 3, is provided with two upper and lower two through the entire water retaining plate 5 The vertical rib 51 of the end divides the water deflector 5 into three parts of a left zone, a middle zone B and a right zone C, the vertical rib 51 facing Said outlet 3. The water deflector 5, the vertical rib 51 and the water storage chamber 4 are integrally formed with the toilet seat.

When the toilet seat of the embodiment is flushed, as shown in Figs. 2 and 4, the water in the water tank first enters the water storage chamber 4 from the water inlet 2 of the water pipe 6, and then flows out from the water outlet 3, and the water flows. After the two vertical ribs 51 of the water deflector 5 are divided into three water flows; the water flow divided into the left zone A and the right zone C of the water deflector 5 is guided to the sink 1 as indicated by the arrow in FIG. The inner wall 7 for cleaning the toilet seat; the water flow divided into the middle portion B of the water deflector 5 as shown by the arrow in Fig. 2, flows directly into the horse located below the water deflector 5 The inner wall 7 of the barrel seat is used for flushing. Therefore, the effect of automatically cleaning the inner wall of the toilet seat is achieved, and the water passage in the toilet seat is not required, thereby avoiding the problem that the water passage gathers dirty things and is difficult to clean, and there is no need to worry about crawling in; Structure, simple assembly, long-lasting durability, vertical ribs not only play the role of water and pressure reduction, but also strengthen the structural strength of the water retaining plate.

Preferably, the water outlet 3 is semicircular, the upper half is semicircular hollow, the lower edge of the water outlet 3 is higher than the bottom wall of the water storage chamber 4; the water inlet 2 is circular, It is stated that the nozzle 3 and the water inlet 2 have the same diameter. The semicircular structure is simple and easy to fire. Since the inlet 2 and the outlet 3 have the same diameter, but the outlet 3 is semicircular, the water inlet 2 has twice the water passing capacity of the outlet 3, so the water entering the water conduit 6 Most of them will be temporarily stored in the water storage chamber 4, and then gradually flow out from the water outlet 3, which slows the speed of the water flow to achieve a better water separation effect, and because there is always a part of water in the water storage chamber 4 Therefore, there are no pests such as cockroaches and cockroaches hiding in the water inlet 3.

Preferably, a lower portion of the left area A and the right area C of the water deflector 5 is provided with a recess 52. The recess 52 is capable of adjusting the direction of movement of the water flow to form a small vortex that moves toward the sink 1 .

Preferably, the lower edge of the water deflector 5 is located below the lower edge of the water outlet 3. The arrangement is such that the water flow is sufficiently blocked by the water deflector 5, and the water flow can enter the interior of the toilet seat after being shunted by the water deflector 5.

Preferably, the water inlet 2 and the water outlet 3 have a diameter of 4-6 cm. The vertical rib 51 has a thickness of 0.3-0.8 cm, a height of l-2 cm, and a length of 5-8 cm. The size is suitable for 4-6 liters per flush, just enough to complete the amount of water for a flush, which effectively saves the use of flushing water. Because of the flushing, a part of the water flows through the inner wall 7 and then flows into the drain pipe. The water flows in all directions. Entering the entrance to the drain pipe greatly enhances the ability to flush the blowdown. The experiment shows that when urinating and urinating, only 2.7 liters of water is needed. Complete the flushing work; When flushing the stool, only 4.5 liters of water is needed to complete the flushing work, which greatly saves the amount of flushing water.

The beneficial effects of the invention are as follows: 1. The open water tank 1 is used instead of the closed water passage, which not only achieves the purpose of automatically cleaning the inner wall 7 of the toilet seat, but also solves the problem that the water passage is dirty and inconvenient to clean. 2. The water retaining plate 5, the vertical rib 51 and the toilet seat are integrally fired, and the structure is durable and reliable; 3. The structure of the water retaining plate 5 is simple and convenient for production; 4. The water pipe 6 is provided with a water storage chamber 4, Therefore, there are no pests such as cockroaches and cockroaches in the water inlet 2; 5. When the sewage is discharged, a part of the water flows through the inner wall 7 and then flows into the drainage pipe, and the water flows into the entrance of the drainage pipe in all directions, greatly enhancing the rushing. The ability to discharge sewage, thereby reducing the amount of flushing water, requires only 4.5/2.7 liters of water (fecal/urin) to achieve the effect of flushing.
