Description
Technical Field
The invention relates to the technical field of controllers for related equipment in the field of kitchens and bathrooms such as a vacuum toilet and the like, and particularly relates to a manual magnetic suction opening and closing type controller, which belongs to the technical field of controllers for related products such as the vacuum toilet and the like needing pneumatic control for vacuum pollution discharge.
Background
Based on the vacuum technology of the pressure difference formed between the pressure lower than the atmospheric pressure and the atmospheric pressure, the human excrement and garbage in the vacuum closestool are discharged into a vacuum sewer pipe after passing through a vacuum drain valve (called a vacuum diaphragm valve abroad and a diaphragm valve domestically) and a manual ball valve under the action of a controller, and then are discharged into a vacuum sewage conveying pipeline system; the basic working principle is as follows: when the vacuum closestool is flushed, the vacuum blow-down valve is opened after the button of the controller is pressed, and the gas-liquid solid garbage mixture is discharged into the sewer pipe after passing through the vacuum blow-down valve and the manual ball valve by depending on the driving force generated by the difference of gas pressure acting on the sewage and solid garbage mixture in the vacuum closestool, so that the garbage in the closestool is cleaned. When the closestool does not need to be flushed, the controller is reset in a delayed mode, the vacuum blowoff valve is closed, and then the power source of the pressure difference generated in the vacuum closestool and on two sides of the solid garbage mixture is stopped, so that the closestool stops working.
Compared with the traditional gravity siphon type closestool and the direct-discharge type closestool, the vacuum closestool has the main advantages of saving energy and water and no hidden trouble of odor leakage, so that the vacuum closestool is widely applied to the fields of hospitals, schools, hotels and the like.
It is well known that the controller of the vacuum toilet is frequently failed and inconvenient to use during operation, and the controller types are as follows:
firstly, the controller is purely mechanical, and is mainly controlled by utilizing a lever mechanism and a cam mechanism, and reference patents include CN1201057C and US 6128789; the controller has the advantages of large number of parts, poor reliability, heavy weight and large volume due to related mechanical parts.
The pneumatic control type comprises two types of controllers:
(1) single button controllers such as CN200680003008.7, CN201580081233.1, US5069243, US4373838, US4171853, US 5570715;
(2) a dual button controller such as CN111677069A size water dual button controller and its vacuum sewer system.
The reasons and disadvantages for these controller failures are:
firstly, the mechanical electric controller has a plurality of related mechanical parts, a complex structure, poor reliability, heaviness and large volume, and the vacuum toilet is completely paralyzed particularly under the condition of flood disasters.
Secondly, a known pneumatic controller (i.e. a spring-damping delay control device for vacuum toilet related equipment, with patent number CN 111677069A) has a function of pressing for delay on and a function of non-pressing for off, and has the following technical problems: firstly, the piston technology has the problems of high manufacturing precision and high cost; secondly, the large water button and the small water button are eccentrically arranged, and certain bending moment force is generated on the valve rod of the execution assembly, so that the execution assembly is poor in rebound and even blocked; thirdly, the lip-shaped sealing ring has poor sealing performance, short service life and large frictional resistance with the rod, which results in a large button force ratio; the pressures on the upper end surface and the lower end surface of the valve rod of the actuating assembly are different, so that the resilience spring force is large, and the button force is large; fourthly, the execution assembly can be influenced by the pressure fluctuation to delay the time effect and accuracy; fifthly, the opening pressure of the steel ball-spring type one-way valve is very high, and the requirement of high sensitivity and low opening pressure cannot be met; sixth, poor drainage of the chamber can cause a reduction in the useful life of the components therein.
Therefore, aiming at the defects of the pneumatic control controller, the invention develops a controller which is suitable for the vacuum closestool and the like in the related field of sewage drainage by utilizing the vacuum technology, namely a manual magnetic suction open-close type controller, so as to solve the problems in the prior art, and the technical scheme which is the same as or similar to the pneumatic control controller is not found through retrieval.

The working principle of the invention is as follows:
in the non-working state: as shown in fig. 19, the button assembly 2 rebounds to the top under the action of the first return spring 24, at this time, the distance between the magnet 23 and the lower insert 31 is too far, and the magnetic force of the magnet 23 is not enough to overcome the elastic force of the second return spring 32 at the upper end of the plug 3, so that the plug 3 closes the vent hole 19 under the action of the second return spring 32, and the vacuum pipeline 161 is not communicated with the second chamber 12; under the action of the orifice 421 on the small bellows 42, air is in the whole air pipeline 171 (the path through which the thick solid line passes in fig. 5), and at this time, air is in the second upper chamber 131 and the second lower chamber 132, the air pressure is the same, and the valve core assembly 4 blocks the fifth chamber 15 under the action of the spring force of the third return spring 43; due to the existence of the groove 411 on the side wall of the valve rod 41, the second lower chamber 132 is communicated with the fourth chamber 14 at this time, the air port 17 is communicated with the second lower chamber 132, the output port 18 is communicated with the fourth chamber 14, further, the air port 17 is communicated with the output port 18, air is introduced at the output port 18, and the flow path of the air is shown by the thick dotted line in the figure.
Under the working state: as shown in fig. 20, in the process of moving the button assembly 2 downward, the force applied by the hand of a person overcomes the spring force of the first return spring 24, the magnet 23 is continuously close to the lower insert 31, when the distance between the two is gradually reduced, the magnetic force is continuously increased, the plug 3 and the lower insert 31 are attracted and raised by overcoming the spring force of the second return spring 32, the vent hole 19 is opened, the vent hole is too late to vent due to the orifice 421 on the small corrugated diaphragm 42, vacuum is formed in the second upper chamber 131 at this time, air is in the second lower chamber 132, a pressure difference is formed between the upper end and the lower end of the small corrugated diaphragm 42, and an upward differential pressure is generated, the valve core assembly 4 moves upward, the sealing plate 412 is attached to the upper end face of the fourth chamber 14, the communication between the second lower chamber 132 and the fourth chamber 14 is closed, the fourth chamber is communicated with the fifth chamber 15 at this time, and the vacuum port 16 is communicated with the fifth chamber 15, the output port 18 is in communication with the fourth chamber 14, and the vacuum port 16 is in communication with the output port 18, and a vacuum is formed at the output port 18, the path of the vacuum is shown by the thick dashed line, and the path of the air is shown by the thick solid line.
In the time delay function state: the flushing water quantity adjusting assembly 7 is adjusted to be in a large flushing mode, because in the working state, air in the first lower cavity 112 is discharged out of the valve body 1 through the check valve assembly 5, along with the leaving of hands, the button assembly 2 starts to reset and rebound under the action of the first reset spring 24, air needs to be continuously supplemented in the first lower cavity 112, and due to the flow limiting effect of the needle valve assembly 6, the resetting time is prolonged, and further the time delay function is realized.
