Background

Nearly 2 hundred million households in more than 5 hundred million families in China are provided with the closestool, and more than nine times of the simple closestool is used.

The simple toilet water tank is high in height and high in water consumption, occupies a toilet space, is not clean in washing or has small replacement force, and is particularly qualified when the pipe diameter of national standard sewage discharge pipe in China reaches 41 mm, and pipeline blockage can easily occur in many products in the market during use. If the drain pipe is thickened to 50 mm, the siphon is difficult to form, and the water-saving index is difficult to realize.

The users using the closestool are generally urban residents, urban water supply has 2-3 kilograms of water pressure in principle, and the standard water pressure of large and medium-sized cities is 4-6 kilograms. With the popularization of rural water improvement, most of the farmer families also supply water with the water pressure of more than 1 kilogram. If the water pressure is not about 1 kilogram, the water inlet valve can not be opened. The toilet bowl used by people firstly adds tap water into a water tank, and turns the water with higher pressure into open non-pressure water. The height of the water tank is generally only 30 cm, that is to say, only about 0.03 kg of flushing water pressure can be generated, so that the washing is powerless, the replacement effect is poor and even the sewage discharge pipe is blocked.

To solve the problem of replacement, an additional set of water inlet valves have been proposed to assist in spraying. However, the water inlet valve is a very precise device, and is often blocked by impurities in the water. The failure rate is doubled by adding one more water inlet valve, and the after-sale service is very troublesome. Furthermore, the cost of the inlet valve is expensive, and if a linkage is added, the manufacturing cost is high.

The more serious problems are: if a whole set of water inlet valve is not additionally arranged, the water flow conversion device is difficult to be manufactured with a simple structure and light operation under the action of strong tap water pressure.

What is a simple way to use the kinetic energy of tap water to help the toilet replace? I discussed below.

SUMMERY OF THE UTILITY MODEL

The utility model relates to a sanitary wares accessory especially relates to one kind by the linkage main shaft with the balanced valve block of flushometer, the balanced valve block of moisturizing valve is balanced in the nozzle side with the produced moment distribution of throttle side received the rivers pressure, and make the balanced valve block of flushometer, the balanced valve block of moisturizing valve becomes certain opening between the two, close the poor structure of angle together, in order to realize the flexible rotation from top to bottom of linkage rocking arm, float cup control by the accuse time through the linkage rocking arm, the rivers that make the outlet pipe have accomplished washing or replacement process to the closestool by the moisturizing delivery port to the rinsing of closestool water tank after just carry out the balanced valve linkage of moisturizing and help towards the closestool water key.

We know that: the butterfly valve has the characteristics of small water resistance and light opening and closing. If the valve plate is distributed and balanced by the valve shaft according to the moment generated by the water flow pressure on the nozzle side and the throttling side, the valve with light opening and closing can be realized.

The above technical problem of the utility model is that help towards the closestool water key and solve through providing the balanced valve linkage of a following structure, this balanced valve linkage helps towards the closestool water key and includes: inlet tube, outlet pipe, outlet opening, the outer bucket of float, the conduction pole, the lever, the fulcrum, block up, the pressure release hole, differential pressure valve assembly, linkage rocking arm, time control float cup, the hole of adjusting time, ejector pin, the float that resets, water container, play water connecting pipe, balanced valve assembly, flushometer sealing washer, linkage main shaft, the balanced valve block of flushometer, wash the delivery port, valve spacer plate, moisturizing, the balanced valve block of moisturizing valve, the sealing washer of moisturizing valve, its characterized in that: the moment distribution generated by the water flow pressure on the nozzle side and the throttling side of the flushing valve balance valve plate and the water replenishing valve balance valve plate is balanced by the linkage main shaft, and the flushing valve balance valve plate and the water replenishing valve balance valve plate are connected together in a certain opening and closing angle difference structure, so that the linkage rocker arm can flexibly rotate up and down, and the water flow of the water outlet pipe is controlled by the time control float cup through the linkage rocker arm, so that the water replenishing is carried out on the water tank of the closestool through the water replenishing water outlet after the flushing water outlet is washed or replaced by the closestool.

The utility model discloses balanced valve linkage helps towards closestool water key compares with the existing closestool washing mode in market and has following advantage:

firstly, the washing force and the replacement force are enhanced. For the user, powerful washing and replacement forces are the basic criteria for judging the function of a toilet. However, it is impossible to produce more desirable effects due to the limitation of the height of the toilet tank. Especially for the toilet with a lower water tank, water can pass around the toilet bowl easily. The international standard for the brushing force cannot be strictly specified, and only the standard is calculated to reach the standard when water passes through. In fact, the brushing force is directly related to the frequency with which the user brushes the bowl and severely affects the replacement effectiveness. As for the hot-sold closestool products in the current market, the low-water-tank closestool has poor washing effect, and the replacement effect of the medium-water-tank closestool or the high-water-tank closestool also has larger space for promotion. Of course, this cannot be achieved without special measures. The utility model discloses the effect of balanced valve linkage help towards closestool water key is directly used for washing the water pressure that the running water supplied water and carries out the moisturizing to the water tank after replacing again, and water supply water pressure is higher, and washing power and replacement power are just bigger. And according to the needs of users, the time for assisting the washing and the spraying by the water pressure of tap water can be randomly adjusted by the time-controlled float cup. Therefore, the washing power and the replacement rate of the toilet bowl with the low water tank can be improved by 2-5 times no matter the toilet bowl with the low water tank or the toilet bowl with the high water tank.

And secondly, the large-pipe-diameter closestool is convenient to produce. The pipe diameter standard of the toilet blow-off pipe in developed countries is 50 mm, and the pipe diameter standard of the toilet blow-off pipe in China is 41 mm. China is a green developing country and advocates water conservation, so the sewage discharge pipe cannot be specified too thick. However, it is known that 41 mm is one third less than the water passing area of a drain pipe with a pipe diameter of 50 mm. The thicker the pipe diameter, the more difficult it is to form a siphon, and the greater the water consumption. Certainly, the small-caliber sewage draining pipe has the advantage of water saving, but is easy to form blockage. The utility model discloses the high water pressure of running water directly acts on the injection after the balanced valve linkage helps towards closestool water key uses, improves the kinetic energy of injection many times in the twinkling of an eye, and powerful rivers make siphon power form at once. In contrast, the effect of the size of the pipe diameter on the formation of the siphon force is negligible, so that the production of a toilet with a large pipe diameter is facilitated.

Thirdly, cost is saved and failure probability is reduced. The water pressure of tap water is used for assisting the washing or the spraying of the closestool, so that a good method for solving the using performance of the closestool is provided. However, there are many options for implementing the method, and the most common method is to add a whole set of water inlet valve device. Most of the water inlet valves in the market adopt the principle of a differential pressure valve, and the water inlet valves are light and handy to open and close, stable in performance and relatively silent. The problem is that the valve has higher requirement on water quality, and the valve core is easy to block and can not be closed or opened in some cases. If we add a whole set of water inlet valve device to help washing or replacement, the failure rate is doubled. The utility model discloses balanced valve linkage helps towards closestool water key is a rivers conversion and the time control device that adds behind the delivery port of original water intaking valve, and this device simple structure stable performance also does not have the requirement to quality of water. Thereby saving both cost and failure probability.

Detailed Description

Fig. 1 and 2 show a specific embodiment of the balance valve linkage flushing-assisting water key of the toilet of the present invention. In fig. 1: 1-11 are illustrated as if they were a common inlet valve configuration, except that the outlet pipe 2 is converted to an interface with the balanced valve assembly 19. When the water level in the water tank is low, the drain hole 3 is exposed, the outer barrel 4 of the floater is filled with water, the floater 5 sinks, the plug 9 is separated from the pressure relief hole 10, and the high-pressure water flow of the water inlet pipe 1 is communicated with the water outlet pipe 2. When the water in the water tank reaches a set water level, the floater 5 floats upwards, the conduction rod 6 seals the plug 9 and the pressure relief hole 10 through the lever 7 and the fulcrum 8, at this time, no pressure difference exists in the pressure difference valve assembly 11, the high-pressure water flow of the water inlet pipe 1 is isolated from the water outlet pipe 2, and the water outlet is stopped.

In the process of adding water into the water tank, the water outlet pipe 2 is not directly communicated with the water tank, but is added with water into the water tank after passing through the balance valve assembly 19.

Please refer to fig. 2: the upper area and the lower area of the flushing valve balance valve plate 22 and the water replenishing valve balance valve plate 26 are distributed by the linkage main shaft 21 according to the moment generated by the water flow pressure on the nozzle side and the throttling side under the water pressure of about 3 kilograms, so that the linkage rocker arm 12 can be operated easily. The flushing valve sealing port 20 and the water replenishing valve sealing port 27 can be respectively coupled with a flushing valve balance valve plate 22 and a water replenishing valve balance valve plate 26 to be opened and closed, and the two sets of valve plates form a certain opening and closing angle difference structure on the linkage main shaft 21. The upstream surfaces of the flushing valve sealing port 20 and the water replenishing valve sealing port 27 are respectively communicated with the water outlet connecting pipe 18, the flushing valve sealing port and the water replenishing valve sealing port are separated by a valve partition plate 24, and the water outlet surfaces of the flushing valve sealing port and the water replenishing valve sealing port are respectively connected with a flushing water outlet 23 and a water replenishing water outlet 25. The linkage rocker arm 12 is connected with the linkage main shaft 21 and the time control float cup 13.

Please refer to fig. 1 again: the bottom of the timing float cup 13 is provided with a timing hole 14. The reset floater 16 in the water container 17 always has a constant buoyancy to act on the time control float cup 13 through the mandril 15.

In the specific implementation process, the design that the structures of the flushing valve sealing port 20 and the water replenishing valve sealing port 27 are different in opening and closing angles on the linkage main shaft 21 is particularly noticed, and the floating cup 13 can be matched with the up-and-down moving amplitude according to the time control; the buoyancy of the reset floater 16 is matched with the water quantity of the time control cup 13.

When the toilet is not used: when the water in the water tank of the closestool is full, the buoyancy of the floater 5 seals the pressure relief hole 10 through the plug 9, and the differential pressure valve assembly 11 is in a closed state. At this time; the water outlet connecting pipe 18 is free of water, the flushing valve sealing port 20 is in a closed state, the water replenishing valve sealing port 27 is in an open state, the floating cup 13 is in a horizontal state during control, the reset floater 16 is in a floating state, and the flushing water outlet 23 and the water replenishing water outlet 25 are in a static state.

When the toilet starts to flush: the water level in the water tank of the closestool instantly drops to the shallowest water level, the buoyancy of the floater 5 is lost, the plug 9 is separated from the pressure relief hole 10, and the differential pressure valve assembly 11 is in an opening state. At this time; the water outlet connecting pipe 18 is filled with water flow with the same pressure as tap water, the time control float cup 13 is in a falling state, the water supply valve sealing port 27 is in a closing state, the flushing valve sealing port 20 is in an opening state, the reset float 16 is in a sinking state, and strong water flow from the flushing water outlet 23 immediately starts to help the closestool to be washed or sprayed and replaced.

Generally speaking, the toilet bowl completes a flushing cycle for 5-8 seconds, and when the volume of the time control cup 13 is designed, the combined control reset time of the buoyancy of the reset floater 16 and the size of the time adjusting hole 14 is also 5-8 seconds. The precise requirements of the specific time for the flushing mode of different toilets can be adjusted at will.

When the toilet is flushed for a few seconds: when the water in the timing cup 13 is nearly drained, the reset floater 16 jacks up the linkage rocker arm 12, so that the water replenishing valve sealing port 27 is in an open state, and the flushing valve sealing port 20 is in a closed state.

When the water in the tank is nearly full: the water outside the outer barrel 4 of the float overflows to float the float 5, the plug 9 immediately seals the pressure relief hole 6 under the action of the lever 7, then the differential pressure valve assembly 11 is closed, the water outlet connecting pipe 18 has no water to flow out, and the working state of each accessory is restored to the state when the closestool is not used.

So as to reciprocate.

The balance valve linkage flushing-assisting water key of the toilet can have various changes and modifications without limitation to the specific structure of the above embodiment, such as various changes of the structure modes of the balance valve block of the flushing valve, the balance valve block of the water replenishing valve and the linkage main shaft. In summary, the scope of the present invention for the balanced valve linkage assisted flush toilet water key should also include such exchanges, substitutions and modifications as would be apparent to one of ordinary skill in the art.
