Description

An intelligent water-saving squatting pan for public toilets

technical field

The utility model belongs to the technical field of intelligent water-saving, in particular to an intelligent water-saving squatting toilet in a public toilet.

Background technique

At present, squatting toilets in public toilets on the market mainly clean excrement by flushing with water. The most common squatting toilet in public toilets can be flushed by pressing the flush button, but due to human inertia and the same amount of flushing water for urine and urine, it greatly wastes water resources. And once the squatting pan pipeline is blocked, no one finds it, which brings great changes to the user. Though the appearance of water-saving toilet is arranged on the market, water-saving effect is all not particularly satisfactory.

Nowadays, intelligence has become a trend of social development. Therefore, people need the appearance of toilets that meet their own requirements more.

Utility model content

The purpose of the utility model is to provide an intelligent water-saving squatting toilet in public toilets, which solves the problems in the prior art that the squatting toilets in public toilets waste a lot of water resources and are easily blocked to cause inconvenience.

The technical solution adopted by the utility model is that an intelligent water-saving squatting pan in public toilets includes a squatting pan body connected with a water tank, a sewage pipe is arranged at the bottom of the squatting pan body, and a wall around the inner cavity of the squatting pan body is provided with A liquid level sensor, a weight sensor is also arranged in the squatting pan body, a single-chip microcomputer, a solenoid valve and a water flow sensor are arranged in sequence from top to bottom in the water tank, and the single-chip microcomputer is also connected with the liquid level sensor and the weight sensor.

The utility model is also characterized in that,

The sensing surface of the liquid level sensor faces the inner cavity of the squatting pan body.

The weight sensor is placed at the lowest part of the squatting pan body, and the sensing surface faces the inner cavity of the squatting pan body.

The microcontroller is placed in a waterproof box in the water tank.

A buzzer is also connected to the microcontroller.

The beneficial effect of the utility model is that an intelligent water-saving squatting toilet in a public toilet can control the water flow sensor through the electromagnetic valve to achieve water-saving flushing, which achieves the water-saving effect, and can buzzer when the sewage pipe is blocked. Automatic alarm to remind the staff to come for maintenance, and at the same time, the solenoid valve cuts off the water source to avoid water waste.

detailed description

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

The utility model is an intelligent water-saving squatting pan in a public restroom, the structure of which is shown in Figure 1, comprising a squatting pan body 1 connected to a water tank 10, and the bottom of the squatting pan body 1 is provided with a sewage pipe 4, wherein the public toilet Left infrared transmitting tube and right infrared receiving tube are installed on the bathroom wall, as shown in Fig. The interior is provided with a single-chip microcomputer 7, a solenoid valve 6 and a water flow sensor 5 sequentially from top to bottom, and the single-chip microcomputer 7 is also connected with the liquid level sensor 3 and the weight sensor 2. The specific control circuit is shown in Figure 3, and the liquid level sensor 3 senses Face towards the inner cavity of the squatting pan body 1, the weight sensor 2 is placed at the lowest part of the squatting pan body 1, the sensing surface faces the inner cavity of the squatting pan body 1, the single-chip microcomputer 7 is placed in a waterproof box 9 in the water tank 10, and the single-chip microcomputer 7 is also connected buzzer8.

The utility model is an intelligent water-saving squatting toilet in a public restroom. The working principle is as follows:

When the left infrared emitting tube and the right infrared receiving tube are cut off for the second time, after detecting that the toilet occupant leaves, the detection signal is input to the weight sensor 2 placed at the bottom of the squatting pan body 1, and the weight sensor 2 receives the signal, and the single chip microcomputer 7 Make a logical judgment based on the weight of the excrement, generate a control signal for controlling the amount of flushing water, transmit the signal to the solenoid valve 6, and control the water flow sensor 5 to perform flushing. After that, the liquid level sensor 3 works to measure the height of the liquid level in the squatting pan body 1. If the liquid level exceeds the preset range, the buzzer 8 will give an alarm, and the solenoid valve 6 will cut off the water source simultaneously.

The utility model is an intelligent water-saving squatting toilet in a public toilet. The working process flow chart is shown in Figure 4, specifically as follows:

When the user leaves, the infrared ray is cut off for the second time, and the weight sensor 2 works. When it is detected that the excrement weight is less than 7.5g, the single-chip microcomputer 7 transmits the signal to the solenoid valve 6 by controlling the driving circuit, and the water flow sensor 5 is controlled to perform small flow flushing; when it is detected that the excrement weight is greater than 7.5g, the single-chip microcomputer 7 transmits the signal Supply the solenoid valve 6 to control the water flow sensor 5 to perform high-flow flushing; after flushing, when the liquid level sensor 3 detects that the liquid level in the squatting pan body 1 is greater than 7cm, it means that the squatting pan is blocked, and the buzzer 8 alarms to remind maintenance The personnel comes to overhaul, and solenoid valve 6 cuts off the water source. If it is less than 7cm, it means that the squatting pan sewage pipe 4 is normal. Among them, 7.5g is the measured mass critical value; 7cm is the measured height.

The utility model can not only wash the excrement with a large or small flow rate, save water, but also can give an alarm to the blockage of the sewage pipe and remind maintenance, and the electromagnetic valve cuts off the water source. It perfectly solves the problems of water resource waste and pipeline blockage that no one finds out.
