Abstract

A water-saving pressure difference toilet, which includes: a toilet seat body, a toilet seat cushion and a toilet lid; the inside of the toilet seat cushion includes an O-type airtight ring; the middle part of the toilet lid includes a soft and tough film. The inside of the lid contains an O-type airtight ring; when flushing, close the toilet lid. At this time, the O-type airtight ring on the inside of the toilet lid and the toilet seat cushion form an airtight structure. The O-type airtight ring on the inside of the toilet seat cushion Forming an airtight structure with the toilet seat body, these two O-shaped airtight rings form an airtight space between the top of the waste water inside the toilet and the toilet lid. When flushing, the toilet wastewater flowing downward by gravity will cause the pressure in the airtight space to decrease. At this time, a pressure difference is formed between the external atmospheric pressure and the pressure in the airtight space. This pressure difference forms a net pressure, which is The downward thrust will push the soft and flexible membrane downward, and at the same time push the toilet waste water downward, causing the toilet waste water to be discharged quickly. With the thrust formed by this pressure difference, the toilet waste water can be discharged when there is less water. In this case, the waste water is discharged, which can achieve the purpose of saving water resources.

Description

Water saving toilet with differential pressure

This creation is about a water-saving pressure difference toilet, specifically a type that uses pressure difference to generate net thrust, which can discharge toilet wastewater when the water supply is small, so as to achieve the field of toilet saving water resources.

The toilets on vehicles that need to save space, such as airplanes and ships, are vacuum toilets made using the principle of vacuum suction. This toilet needs a vacuum pump to achieve vacuum. If you want to implement this vacuum toilet in your home, It will be very expensive and complex in structure

In view of the improvement of the above-mentioned prior art, the present inventor proposes a structure of a differential pressure toilet.

The main purpose of this invention is to provide a toilet structure that utilizes pressure difference to achieve the purpose of water saving.

Based on the above purpose, the present creation is a water-saving pressure difference toilet, which includes: a toilet seat body, a toilet seat cushion and a toilet cover; the toilet seat cushion is located on the toilet seat body, and the inner side contains an O type air-tight ring; the toilet seat is set on the toilet seat cushion, the middle part contains a soft and tough film, and the inside of the toilet seat contains an O-type air-tight ring; when flushing, close the toilet cover, and the toilet The O-type airtight ring on the inside of the cover and the toilet seat cushion form an airtight structure. The O-type airtight ring on the inside of the toilet seat cushion forms an airtight structure with the toilet seat body. These two O-type airtight rings make the connection between toilet water and toilet seat An airtight space is formed between them. When flushing, the toilet water flowing downward by gravity will cause the pressure in the airtight space to decrease. At this time, a pressure difference is formed between the external atmospheric pressure and the pressure in the airtight space. This pressure difference forms a net pressure, which is The downward thrust will push the soft and flexible membrane downward, and at the same time push the toilet waste water downward, causing the toilet waste water to be discharged quickly. With the thrust formed by this pressure difference, the toilet waste water can be discharged when there is less water. In this case, the waste water is discharged, which can achieve the purpose of saving water resources.

In order to facilitate the review committee to have a further understanding of the purpose, shape, structural device characteristics and functions of this creation, the detailed description is as follows:

1:Toilet seat cushion

11: O-type airtight ring inside the toilet seat cushion

2:Toilet cover

21: The soft and flexible film in the middle of the toilet seat

22: O-type airtight ring inside the toilet seat

3: Toilet seat body

31:Toilet water

32: The airtight space formed between the toilet water and the toilet seat

Figure 1 is a schematic diagram of the pressure difference water-saving toilet of this creation.

Figure 2 is a schematic diagram of the operation principle of the pressure difference water-saving toilet of this creation.

Please refer to Figures 1 and 2. This invention is a water-saving pressure difference toilet, which includes: a toilet seat body 3, a toilet seat cushion 1 located on the toilet seat body 3, and a toilet seat seat 1 located on the toilet seat cushion 1. A toilet seat 2; the inner side of the toilet seat cushion 1 includes an O-type airtight ring 11; a soft and tough film 21 in the middle of the toilet seat 2; the inner side of the toilet seat 2 includes an O-type airtight ring 22.

When flushing, the toilet lid 2 is closed. At this time, the O-type airtight ring 22 inside the toilet lid 2 and the toilet seat cushion 1 form an airtight structure. The O-type airtight ring 11 inside the toilet seat cushion 1 is in contact with the toilet seat body. 3 forms an airtight structure, and these two O-shaped airtight rings form an airtight space 32 between the toilet water 31 and the toilet lid 2 . When flushing, the toilet water 31 flowing downward by gravity will cause the pressure of the airtight space 32 to decrease. At this time, a pressure difference is formed between the external atmospheric pressure and the pressure of the airtight space 32. This pressure difference forms a net pressure. , which is a downward thrust. This thrust will push the soft and flexible membrane 21 downward, and at the same time push the toilet water downward, thus causing the toilet water 31 to be discharged quickly. With the thrust formed by this pressure difference, The toilet water 31 can be discharged when there is less water, thus saving water resources.

To sum up, the water-saving pressure difference toilet of this invention has a simple structure, low cost and is easy to use. When flushing, the pressure difference forms a downward thrust, which pushes the soft and tough silicone film downward. At the same time, the toilet water is pushed down, so the purpose of saving water can be achieved.

The above are only the best specific embodiments of this invention, but the structural features of this invention are not limited thereto. Any changes or modifications that can be easily imagined by anyone familiar with the art in the field of this invention can be covered. Within the following patent scope of this case.

1:Toilet seat cushion

11: O-type airtight ring inside the toilet seat cushion

2:Toilet cover

21: The soft and flexible film in the middle of the toilet seat

22: O-type airtight ring inside the toilet seat

3: Toilet seat body

Claims (2)

A water-saving differential pressure toilet includes: a toilet seat body, and a toilet seat cushion, which is arranged on the toilet seat body. The inside of the toilet seat cushion includes an O-shaped airtight ring; and a toilet cover, whose shaft is arranged on the toilet seat. The seat cushion is a soft and flexible film in the middle of the toilet seat. The inside of the toilet seat contains an O-shaped airtight ring. When the toilet seat is to be flushed, the O-shaped airtight ring on the inside of the toilet seat is in contact with the toilet seat cushion. Forming an airtight structure, the O-type airtight ring on the inside of the toilet seat cushion forms an airtight structure with the toilet seat body. These two O-type airtight rings form an airtight space between the toilet water and the toilet lid; when flushing, The toilet water flowing downward by gravity will cause the pressure in the airtight space to become smaller. At this time, a pressure difference is formed between the external atmospheric pressure and the pressure in the airtight space. This pressure difference forms a net pressure, which is the downward thrust. This thrust will push down the soft and flexible membrane, and at the same time push the toilet water down, thus causing the toilet water to be discharged quickly. With the thrust formed by this pressure difference, the toilet water can be pushed down when there is less water. The toilet water is discharged, thus saving water resources. For example, in the water pressure difference saving toilet of claim 1, the soft and tough film wrapped in the middle part of the toilet seat is a silicone film.
