Description

Split type gas accuse button

Technical Field

The utility model relates to the technical field of vacuum sewage collection, transportation and treatment, wherein the vacuum sewage collection technology refers to a front-end device or a product for collecting sewage at a sewage source, including but not limited to various kitchens (such as a toilet, a urinal, a shower room, a bathtub and the like) and sanitary products (such as a vegetable washing tank, a dish washing machine and the like); the vacuum sewage conveying technology is related to the technology of efficiently conveying sewage collected by a front-end device or a product to sewage post-treatment equipment, and comprises core components of a vacuum pump station, a sewage collecting tank, an underground vacuum conveying pipe network system, a vacuum well, a fault detection and diagnosis system and the like; vacuum sewage treatment technique indicates aftertreatment equipment or device, and the primary function is to concentrate the sewage of collecting and carry out solid-liquid separation and purification, and organic fertilizer can be made into to wherein the solid, and sewage realizes green emission after MBR membrane technology filtration purification, the utility model discloses then in particular to be applied to a split type gas accuse button in the vacuum closestool.

Background

In the technical field of vacuum domestic sewage collection, transportation and treatment, vacuum domestic sewage collection is the foremost technology, and the basic realization principle is as follows: first, the sewage collection inlet line (or blowdown inlet line) in the vacuum sewage delivery system is connected to various sewage front end collection devices, including but not limited to various kitchens (such as toilets, urinals, shower stalls, tubs, etc.) and sanitary products (such as sink basins, dishwashers, etc.); secondly, the vacuum pump set generates vacuum in the vacuum sewage conveying system; finally, in the working process of the sewage front-end collecting device, after the vacuum sewage discharge valve is connected, the pressure difference between the external atmospheric pressure and the vacuum value in the pipeline in the vacuum sewage conveying system is acted on the sewage and mixed with air to realize the turbulent conveying of the sewage into the sewage collecting inlet pipeline (or the sewage discharge inlet pipeline).

It is well known that vacuum toilets are a typical representative in vacuum sewage drainage systems; however, the vacuum toilet has the following disadvantages in the use process, when the vacuum toilet flushes and discharges sewage, a user needs to stand up and turn around 180 degrees and then press a flushing button of the vacuum toilet, and other front-end collectors (such as a pneumatic controller driven vacuum squatting pan) using a vacuum sewage discharge valve have similar problems; specifically, the flush button of the vacuum toilet is mounted on the rear upper cover plate of the vacuum toilet, and the flush button at the position is not convenient for use in ergonomics because the user needs to bend down to trigger the flush function, which increases more difficulty and inconvenience for patients with lumbar disc herniation, especially increases the retention time in the bending down flush action under the condition that the flush noise is not effectively solved. The fundamental reason for these problems is that the flush button is integrated into the controller as a whole, and because the controller is relatively large, the controller with the flush button is limited from leaving the vacuum toilet body and its cover plate and being mounted on other places, such as left and right hand side wall surfaces after sitting in a toilet.

Over the past 30 years, researchers in the countries of the europe and the america have tried methods and techniques to reduce the inconvenience of flushing related products such as vacuum toilets in vacuum collection systems, and although the accumulation time of related technologies in the country is short, continuous breakthroughs are made in the accumulation process.

Currently, there are two main types of structure of the touch button (or the actuating button) for the pneumatic control of the vacuum toilet: integral type structure, split type structure.

The invention relates to an integrated structure, and in a Chinese invention patent with the patent number of CN100572703C, a vacuum sewage system is provided, which adopts an integrated structure mode of a trigger control button and a controller, a trigger device of the trigger control button is mainly realized by a spring and an ejector rod reset mechanism, and a flushing action flow triggered by a flushing button is as follows:

(1) starting a flushing button action flow:

upon pressing the actuating means 106 in the control means 105, the control means 105 is actuated, whereby the first valve means 19 with the coupling means 13 is pushed forward against the membrane 14. This movement moves the recess 15 in the first stem 191 towards the first valve seat 192 providing communication between the first and second chambers 1, 2 through the passage thus formed by the recess 15 and the first valve seat 192, thereby allowing atmospheric pressure to flow from the first chamber 1 into the second chamber 2, and subsequent control.

(2) Reset flush button action flow:

before the second valve means 5 reaches its second position (i.e. the end position), the first valve means 19 reaches its forwardmost position, where its further movement is organised by the first valve seat 192, whereby the coupling means 13 is released from the diaphragm 14; this results in the first spring 18 returning the first valve means 19 and the suction cup 13 to their initial position closing the communication between the second chamber 2 and the first chamber 1, and the resetting of the actuating means 106 is completed.

Other patents relating to touch buttons of one-piece construction include: CN202010655551.7, CN 202010710038.3, CN 200680003008.7, CN201580081233.1, the trigger button of the big and small water flush controller and the controller form an integral structure design, and the main parts of the structure comprise a return spring and a button piston rod.

Regarding the split structure, the chinese patent with patent number CN 1201057C and the US patent with patent number US 6128789a adopt a split structure mode of the trigger control button and the controller, the trigger device of the trigger control button is mainly realized by a lever mechanism, a drag line and a cam mechanism, and the flushing action flow triggered by the flushing button is as follows (taking the chinese patent with patent number CN 1201057C as an example):

(1) starting a flushing button action flow:

a release (actuation) device 23 is provided in the valve 10, connected to the valve arm 37, and comprises a locking pin 39, a spring 40 aligned to apply a preload, which keeps the balance arm 37 pressed against the miscellaneous spring 13, and by pressing the pneumatic button 22 on the release device, a drag line 24 pulls the locking pin 39 backwards, thereby causing the arm 37 for the valve 10 to open the valve orifice 17 and close the valve orifice 18, and thus perform the subsequent blowdown and flush actions, thus performing a button-triggered actuation control function.

(2) Reset flush button action flow:

when the piston 7 reaches the uppermost position of the cylinder 6, the cam projection 35 acts on the balance arm in the valve 10, resetting the valve and opening it to provide air from the atmosphere through the tube 21; at the same time the release device 23 is reset so that the operating device is ready for a new discharge flushing action of the vacuum toilet.

In conclusion, the integrated touch button has a simple structure and few parts, but the integrated controller formed by the integrated touch button and the controller has a great requirement on the installation of other places, such as a wall and the like, on a non-toilet body, particularly the depth (or the thickness), so that the application range of the product is limited; in the technical scheme of the split type touch control button, the trigger control button is realized by adopting a lever mechanism, a dragging line (similar to a brake line) and a cam mechanism, so that the split type touch control button has the advantages of more parts, poor reliability and high installation and maintenance cost; consequently need a simple structure, the split type button of pneumatics that pneumatic controller was used among high, the simple to operate's the vacuum closestool of reliability urgently for solve the problem that exists among the prior art, the utility model discloses then developed a split type gas accuse button, through the retrieval, not discover with the utility model discloses same or similar technical scheme.
