Description

Intelligent flushing device of toilet

Technical Field

The utility model belongs to the technical field of intelligence bathroom technique and specifically relates to a toilet bowl intelligence bath device.

Background

At present, along with the continuous perfection of intelligent toilet bowl function, for example, the foot feels bath, off-seat bath, remote control bath etc. receive people's liking more and more. However, there are some disadvantages, when the male user urinates using the toilet, the flushing function is realized by the remote controller or the control switch which is installed at the lower part of the toilet ceramic and can be operated by feet, and the control switch of feet is more convenient to use. The control switch normally adopts three modes: the sensor comprises a mechanical switch, an infrared sensor, a radar sensor and a control unit, wherein the mechanical switch is automatically reset, the infrared sensor is an infrared emission sensing device, and the radar sensor is a radar module for short-distance sensing.

The mechanical switch signal is stable and is not easily interfered by the outside, but the operation requires that the reset switch is kicked to the bottom by feet to trigger a current signal, the feet are uncomfortable due to too much force, the current signal cannot be triggered due to the insufficient reset switch when too little force is exerted, and misoperation is easily caused for people (old people, children and the like) with insufficient perception experience and general knowledge; the infrared induction switch is simple, a switch signal can be triggered only by the fact that a foot stays for 2 seconds before the switch, but the foot is required to be within an infrared irradiation angle range, meanwhile, the switch can be effective only when receiving an infrared reflection signal (about 2 seconds), the experience comfort level is not high, and misoperation (human bodies and objects stay for 2 seconds within the infrared irradiation angle range) can be easily caused by external interference; radar inductive switch is sensitive very much, and the foot stretches into in the radar response area, just can trigger inductive switch, experiences the comfort level and improves greatly, nevertheless because radar inductive switch principle catches object removal signal at certain distance within range, so receive external disturbance easily equally (clean the closestool, drag ground etc.).

Therefore, the prior art has yet to be developed.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned prior art's weak point, the utility model aims to provide a toilet bowl intelligence bath device. The intelligent recognition method aims to solve the problems that the intelligent degree is not high and the recognition accuracy is poor in the prior art.

In order to achieve the purpose, the utility model adopts the following technical proposal:

the utility model provides an intelligent flushing device of a toilet bowl, which comprises a toilet seat, a flusher, a CPU and a balance detection device,

the balance detection device is arranged on the toilet seat and synchronously moves around a shaft with the toilet seat;

when the toilet seat rotates around the shaft to meet the preset conditions, the balance detection device sends corresponding preset signals to the CPU;

and the CPU receives the preset signal and sends a corresponding instruction to the flusher to control the flusher to enter a standby state or flush.

Further, the balance detection device is a mercury tilt switch.

Further, the preset conditions include a first preset condition and a second preset condition, and the preset signals include a first preset signal and a second preset signal;

when the toilet seat rotates around the shaft to meet a first preset condition, the balance detection device sends a first preset signal to the CPU, so that the CPU controls the flusher to enter a standby state;

when the toilet seat rotates around the shaft until a second preset condition is met, the balance detection device sends a second preset signal to the CPU, so that the CPU controls the flusher to flush.

Further, the first preset condition is that the toilet seat ring rotates around the shaft until the mercury tilt switch is closed, and the second preset condition is that the toilet seat ring rotates around the shaft until the mercury tilt switch is opened.

Further, a shaping filter device and a delay working circuit are sequentially connected in series between the balance detection device and the CPU.

Further, the installation angle of the mercury tilt switch is inclined downwards by 7 degrees.

Compared with the prior art, the utility model has the advantages that intelligent identification is carried out by the mercury tilt switch in combination with the opening and closing actions of the toilet seat, so that flushing can be effectively controlled, the actual use action is sensitive, stable and reliable, no misoperation phenomenon exists, the toilet seat is suitable for working in a humid environment, and the service life is long; the problem of mechanical type switch's operation inconvenient, overcome infrared, radar switch and receive external disturbance easily, improve simultaneously and experience the comfort level, can control intelligent toilet bowl through simple the seat circle of closing fast, effectively, accurately and wash by water.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The following description of the preferred embodiments of the present invention is provided for the purpose of illustration and description, and is not intended to limit the invention.

The design principle of the utility model is as follows: the balance sensor made of mercury tilt switch is installed in the toilet seat, and is tilted downwards by about 7 degrees to keep a zero state, when the toilet seat is opened, the zero state is broken, the balance sensor sends a trigger signal, when a user closes the toilet seat after use, the balance sensor recovers the zero state, and the computer sends a flushing instruction to control the action of the flushing valve.

Example 1

Referring to fig. 1, the utility model provides an intelligent flushing device of a toilet, which comprises a toilet seat, a flusher 4 and a CPU, and is characterized in that the intelligent flushing device also comprises a balance detection device 1,

the balance detection device 1 is arranged on the toilet seat ring and synchronously moves around a shaft with the toilet seat ring;

when the toilet seat rotates around the shaft to meet the preset conditions, the balance detection device 1 sends corresponding preset signals to the CPU;

and the CPU receives the preset signal and sends a corresponding instruction to the flusher 4 to control the flusher 4 to enter a standby state or flush.

Further, the balance detecting device 1 is a mercury tilt switch.

when the toilet seat rotates around the shaft to meet a first preset condition, the balance detection device 1 sends a first preset signal to the CPU, so that the CPU controls the flusher 4 to enter a standby state;

when the toilet seat rotates around the shaft until a second preset condition is met, the balance detection device 1 sends a second preset signal to the CPU, so that the CPU controls the flusher 4 to flush.

Further, a shaping filter device 2 and a delay working circuit 3 are sequentially connected in series between the balance detection device and the CPU.

The utility model discloses during operation, when the user lifted the toilet lid from the horizontal state, mercury tilt switch's zero-bit state was destroyed, and CPU received first preset signal, control flusher 4 gets into the armed state, and when the user placed the toilet lid back to water from the state of lifting, mercury tilt switch resumes the zero-bit state, and CPU received the second and predetermines the signal, controls flusher 4 washes by water to stop washing by water after lasting the definite time.

The actual use effect is as follows: the balance sensor made of the mercury tilt switch can be installed inside the toilet seat after shockproof and waterproof treatment, is sensitive in actual use action, stable and reliable, free of misoperation, suitable for working in a humid environment and long in service life.
