Under the condition that the toilet flushing starting button is used for starting the toilet flushing, a user does not need to press the toilet flushing starting button again due to the delay of the toilet flushing after pressing the toilet flushing starting button once. After the toilet flushing starting button is pressed (after the toilet bowl sensor receives a pressing signal of the toilet flushing starting button), the toilet bowl controller can adopt a sound (such as a transient buzzing sound) or a voice mode to prompt that the pressing is successful, and a user can leave after hearing the sound or the voice prompt; in the case of automatic toilet flushing, the user does not need to pay attention to whether toilet flushing is performed, and the toilet controller can prompt to obtain a toilet flushing starting signal from the sensor in an audible mode (such as a short buzzing sound) or a voice mode.

When the toilet is required to be flushed or under other suitable conditions, the corresponding miniature negative pressure pump is controlled to be started through the air source controller, and the miniature negative pressure pump or the buffer cavity is used for supplementing pressure (supplementing negative pressure or vacuumizing) to the air storage cavity, so that the working negative pressure in the air source pipeline is recovered to meet the requirement of flushing the toilet.

The above control may be effected using any suitable prior art. For example, the communication connection between the air source controller and the toilet controller is realized through a wired or wireless communication mode, when the toilet controller detects that the working negative pressure does not meet the starting condition, the toilet controller sends a pressure supplementing signal (a signal for starting the negative pressure pump) to the air source controller, and the air source controller controls the micro negative pressure pump to start according to the pressure supplementing signal. In a time period when the toilet stool is used with high frequency, the air source controller can also automatically collect or receive a sensing signal from the air source pipeline pressure sensor, compare the sensing signal with a starting threshold value (corresponding starting condition) of working negative pressure, and automatically control the micro negative pressure pump to start when the working negative pressure does not meet the starting condition.

In the process of starting toilet flushing, when the fact that the transmission negative pressure does not meet the starting condition/requirement is detected, the toilet controller can send a gas distribution cleaning request signal to a corresponding gas distribution controller (a controller of a gas distribution unit), the gas distribution controller controls the opening (connection) of a gas distribution negative pressure valve control valve according to the gas distribution cleaning request signal, the gas distribution negative pressure valve is further opened, gas distribution cleaning is achieved on a transverse collecting pipeline (or negative pressure branches in other forms), and after gas distribution cleaning, the working negative pressure in the transverse collecting pipeline can be recovered to the negative pressure level of the negative pressure pipeline.

The communication connection between the dispensing controller and the toilet controller can be realized through a wired or wireless communication mode.

A local area network may be provided through which communication connections between the various controllers and sensors and devices (as appropriate) within the system are made.

When the corresponding controllers (e.g., toilet bowl controller, air distribution unit controller) are provided in a matching manner, the negative pressure valve control valves (e.g., toilet bowl negative pressure valve control valve, air distribution negative pressure valve control valve) and the corresponding controllers may be assembled in one housing, and such a combination may be regarded as the corresponding controller provided with the corresponding negative pressure valve control valve.

In the background of the prior art, the controller may be generally provided with a chip capable of operating with software support.

After each negative pressure valve is opened, the negative pressure valve can be automatically closed for a certain time (usually short) under the control of a corresponding controller. The corresponding negative pressure valve control valve can be controlled to be closed through the corresponding controller, and then the control negative pressure of the negative pressure valve is closed, so that the negative pressure valve is closed.

According to actual needs and the prior art, valves can be arranged on related pipelines and equipment to control medium flow, signal flow, negative pressure conduction paths, working modes and the like, the related equipment is switched on or switched off/cut off, the use or the standby of the equipment is determined, and the like.

The three-way joint for realizing one device and two/two sets of devices connected in parallel can be replaced by a three-way valve, and the switching between the related devices/connecting pipelines can be carried out through the three-way valve.

According to actual needs and the prior art, detection meters can be arranged on related pipelines and equipment, and the detection meters comprise but are not limited to various sensors explicitly described in the specification.

The connections involving the pipes may be direct connections or connections made through connecting tubes or other forms of connecting channels.

In the background of the prior art, the negative pressure (transmission negative pressure) in the negative pressure pipeline can be maintained at a lower level, such as-0.3 mbar (relative pressure), and the lower transmission negative pressure can reduce the air consumption of flushing the toilet on one hand and can also reduce the noise during flushing the toilet on the other hand; the requirement of negative pressure (working negative pressure) for opening the negative pressure valve is relatively high, such as-0.4 to-0.5 mbar (relative pressure), so that the reliability of opening the negative pressure valve, the maximization of the opening degree of a sealing membrane of the negative pressure valve and the minimization of the time of opening the membrane are ensured, and the blocking problem of the negative pressure valve is reduced to the greatest extent. Therefore, the air flushing toilet opens the negative pressure valve by using the working negative pressure with higher negative pressure, discharges sewage by using the transmission negative pressure with lower negative pressure, and flushing water can be zero or very little.

Because under the prior art background, all can electrical control equipment for equipment such as various valves, pumps, the sensing signal output of various sensors also can be for the signal of telecommunication, consequently, can set up supporting controlling means and carry out automated control the utility model discloses on mechanical framework's basis, based on the controller of each relevant unit of prior art configuration, each relevant device, through the automatic control of these controllers realization system, the working method that the realization user expected.
