Problems solved by technology

[0002] The vacuum toilet control components of the existing vacuum flush toilets mostly use electronic components, but due to the humid use environment, the electronic components are easily damaged, resulting in extremely unstable performance, and the practicability of these devices has been questioned; in this regard, the industry has developed The use of pneumatic control components is also difficult to popularize and apply due to problems such as complex structure and difficult assembly and maintenance; in view of the above problems, the Chinese patent name is "A Vacuum Flush Toilet" and the patent number is 00223791.1. A new technical solution is proposed. The scheme includes a starting device, a control device, a vacuum toilet and a vacuum feces collection tank, wherein: the starting device is composed of an opening button and an emergency button, and the opening button is connected with a pressure piston and the control device, and its reset is simply a return spring; the control The device has a number of air chambers formed in its housing, a push rod runs through each air chamber, the main and auxiliary valves are fixed on the push rods in turn, and the top of the push rod is provided with a return spring, which is held on the housing to cooperate with each The air flow in the air chamber, the discharge valve and the flush valve of the vacuum toilet are closed under the action of the return spring to complete a working cycle of the control device; the vacuum toilet is composed of a discharge valve, a flush valve and a toilet. No. 3,984,080) are basically the same in structure and will not be described in detail. Its flush valve structure is similar to that of the Swedish product EVAC. The water inlet and outlet of this product are controlled by a diaphragm piston. The action of the diaphragm piston is: The vacuum degree of the air chamber and the suction of the rubber membrane of the piston and the magnetic component will open the diaphragm piston, and the water inlet and outlet will disappear when the above vacuum degree disappears. Under the action of the return spring, the rubber membrane of the piston will return to its original position, the magnetic component will be separated, and the diaphragm will be closed. The piston and the water inlet and outlet are broken. Another structural feature of this product is that the air chamber and the water chamber are composed of two shells respectively; the above technical solution has the following problems:

[0003] 1. Although the structure of the opening button is simple, its reset (that is, cut off after the air is pressed to the control device) is completed by the return spring, which has nothing to do with the function of the control device. Have a negative impact;

[0004] 2. The key components of the control device are the push rod and its return spring. The force of the spring directly affects the opening or closing of the main and auxiliary valves, as well as the functions of the associated air chambers. Since the force is a constant value that cannot be adjusted, Any deviation in processing, assembly, and material may affect the action of the push rod, thereby affecting the effectiveness of the functions of subsequent components such as flush valves and discharge valves;

[0005] 3. The flush valve only relies on the vacuum degree and the return spring to control the opening and closing of the diaphragm piston. Due to its limited function, the action of the flush valve is slow, which may cause unstable performance, unclean suction and discharge, and increased water consumption.
