in the standby state, as shown in fig. 3, the energy storage tank 5 and the L-shaped pipe 6 at the bottom of the toilet bowl are both filled with water, and the waste tank 23 is in a normal pressure state.
S1, a user presses a washing button 26, the duration of pressing the button is about 0.5s generally, and a control module sends a signal to drive a vacuum generator to generate vacuum between a drain valve 24 and a dirt box 23, as shown in FIG. 4, and the vacuum pumping action is realized.
S2, the control module synchronously sends out signals to drive the water pump 4 to work in the process of driving the vacuum generator 25 to vacuumize, so that the water pump pressurizes the flushing water of the clear water tank 22 and enters the energy storage tank 5 to be pressurized for later use.
S3, the vacuum generator 25 continuously works until the vacuum degree set value preset by the control module is reached in the sewage box 23, the control module stops controlling the vacuum generator by the vacuumizing control module of the vacuum generator (namely, the vacuum generator stops working), generally, the vacuum degree set value is-25 kpa, high-pressure water in S2 enters the nozzle and sprays and washes the bedpan 21 according to the flow rate and the flow velocity set by the control module, the washing starting time and the flushing water volume of the high-pressure water are preset by the control module, namely, the bedpan is flushed, in the process, the flushing water is controlled by the flushing solenoid valve, as shown in FIG. 5, generally, the flushing solenoid valve is closed after being electrified for about 1.2S flushing the bedpan; the flushing water effectively flushes the bedpan under pressure, and then the electric control panel 31 and the water pump 4 control to refill the clean water tank 22 with water.
S4, as shown in fig. 6, the control module controls the drain valve 24 to open when the time of the high-pressure water flushing is about to end, the opening of the drain valve is controlled by the drain valve electromagnetic valve at the position, specifically, the drain valve is opened after the drain valve electromagnetic valve is electrified for about 2S, and the dirt in the bedpan 21 is sucked into the dirt tank under the vacuum action of the dirt tank 23, namely, the action of emptying the bedpan is performed.
And S5, the control module closes the drain valve 24 after the drain valve is opened for a preset time period, and cuts off the continuous suction action of the sewage tank on the flushing water in the toilet bowl, wherein in the embodiment, the opening time of the drain valve is about 1.5S, namely the electromagnetic valve of the drain valve is continuously electrified for about 1.5S after the drain valve is opened.
S6, the control module controls the flushing electromagnetic valve to be powered on, flushing water flushes the bedpan 21 for the second time under the action of pressure, the time for the second flushing is about 0.3S, a water bay is formed at a water outlet of the flushing water of the bedpan, even if the bedpan flushes for the second time, and then the flushing cycle is finished. In the process, the inside of the sewage tank is in a normal pressure state. After that, the clear water tank is filled with water again, and the excrement collecting system enters a standby state.
Specifically, the time that the control module controls the drain valve to open in the S4 is generally 0.2-0.5S before the set time of high-pressure water flushing is finished, and the opening time of the drain valve is selected to be about to finish flushing, so that on one hand, concentrated one-time suction treatment of dirt in the bedpan is facilitated, on the other hand, strong suction force of instant vacuum is favorably formed, on the other hand, the vacuum duration is reduced, and compressed air resources can be well saved.
This vacuum intermittent type formula collection just system is through rational design optimization, the counterpulsation water yield, the bath time is set for and is controlled, it reduces the water consumption to improve washing efficiency, nozzle arrangement and structure guarantee that washing water flow orbit cooperatees with the bedpan curved surface, the filth easily falls into the bedpan bottom under gravity and rivers impact, program control carries out when the process of scouring is about to finish and excretes the valve and open the action, the filth passes through the waste tank that the valve of excreting gets into to have certain vacuum state rapidly under the atmospheric pressure effect, realize the bedpan is automatic to be washed, the automatic collection of filth and storage, compact structure, the sexual valence relative altitude, sanitation and hygiene, no peculiar smell leaks, no matter from resource saving, work efficiency is last or each part life is very favorable in its vacuum intermittent type formula.
It should be understood that the above examples are only for clearly illustrating the technical solutions of the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
