Description

Water-closet tank water supply switching device shifter

The utility model relates to a kind of water-closet tank water supply switching device shifter.

Design by present water-closet tank water supply switching, be few at the water tank water amount of commercially available monomer toilet, the problem of water shortage so that the toilet dirt is washed down can take place, during therefore each the bath, can make the part water yield of water inlet device directly be supplied in the toilet, fill up the problem of water volume in water tank deficiency, and once washed down toilet.

It is the creation that known cases such as No. the 235041st, 319264 and 339104, bulletin is arranged to be at aforementioned functional and purpose.

Announce case No. 235041, the secondary ball float of its water supply switching device shifter is established the guide rod top, and it is too of a specified duration that the water supply change action will be postponed, and water volume in water tank need arrive summit, just has action.And No. 319264 case of bulletin then utilizes secondary ball float to drive water inlet control valve, reaching supplies water switches purpose, but directly is located at start axostylus axostyle end because of its ball float, and its shortcoming is that secondary ball float is not supported by any article, easily cause deflection or upper and lower unsteady problem, cause the valve plug keying and have some setbacks.

Announce No. 301324 case and then be provided with the switching blade, switch blade and then driven, spur the ball chain to utilize secondary ball float ascending, descending action, and produce the function that action is switched by a secondary ball float.

Announce No. 339104 case and then utilize secondary ball float to drive switching device shifter, for this reason, second control valve of switching device shifter is provided with spring again, replys action to form, and structure too complexity does not conform with cost.

Reach above-mentioned each case and all transfer valve is combined with secondary ball float, its shortcoming can cause the transfer valve change action uncertain for when secondary ball float ascending, descending has deflection slightly, even stuck situation, and causing supplies water switches the problem that has some setbacks.

For this reason, the long-pending relevant device for many years of the applicant manufacture and design experience, studied at problem of preceding taking off known person and shortcoming.

The purpose of this utility model is to provide a kind of water-closet tank water supply switching device shifter, with the secondary ball float that is sheathed on water device into be subjected to water-driven in the water tank and ascending, descending, and drive transfer valve with the pushing tow pattern and do to supply water and switch, simple in structure, it is extremely convenient that operation is adjusted.

The purpose of this utility model is achieved in that a kind of water-closet tank water supply switching device shifter, includes into water device, it is characterized in that: be arranged with secondary ball float on the water inlet device, this secondary ball float below has hollow groove; Then be provided with switching mechanism in water inlet one side, this switching mechanism is provided with valve seat, this valve seat is provided with the groove of ccontaining transfer valve, and valve seat is established into, delivery port, wherein delivery port is connected with supply channel, and be provided with the ring that combines with valve gap and enclose, transfer valve is provided with upper and lower ring and encloses again, and the little rings of two rings between enclosing enclose; Valve rod is provided with external screw thread again, and bolt unification T type nut on it.

Owing to adopt such scheme: can reach and control the more accurate switching water supply of transfer valve, structure is also simple.

So, can fully understand the utility model for making your juror, it is as follows to depend on graphic explanation now:

Fig. 1 vertical view of the present utility model.

View during Fig. 2 full-water level of the present utility model.

View after Fig. 3 bath of the present utility model.

Fig. 4 such as Fig. 3 part zoomed-in view.

Fig. 5 the utility model part exploded view.

Shown in Fig. 1 and 2, water-closet tank water supply switching construction of the present utility model includes into water device 1, and this water inlet device is provided with guide rail 10 and ball float 2, whether intakes with control water inlet device.And the water inlet device 1 be to be arranged with secondary ball float, this secondary ball float 3 has hollow groove 30 and plural guide groove 31, cooperates the free conversion binding site of aforementioned guide rail to utilize plural guide groove, and makes secondary ball float 3 have the function of certain track lifting.Then be provided with switching mechanism 4 in water inlet device one side, draw switching mechanism 4 and be provided with valve seat 40, this valve seat 40 is established groove 400 and be can be transfer valve 41 and be installed with, and valve seat 40 is established into, delivery port 401,402, wherein delivery port 402 can be connected with supply channel 403, and make supply channel 403 be connected to toilet, give toilet with direct water supply.And establish ring and enclose 404 and can combine with valve gap 405, and transfer valve 41 is installed in the groove of valve seat, make it be limited upper and lower lifting distance.

Transfer valve 41 is provided with upper and lower ring 411,412, and two ring enclose 411,412 and be provided with less ring and enclose 415, this less ring encloses 415 and can be cross or other shape, when being beneficial to the state shown in Fig. 3 and 4, can make into, delivery port being a straight line, and can make water flow in the toilet, but the water in water-closet tank arrives the height (as shown in Figure 2) of designated water level gradually, promptly can make down ring enclose 412 intercepts in going into, between the delivery port 401,402, and making toilet disappear through the situation that this switching mechanism supplies water.Establish external screw thread 420 at valve rod 42 again, combine to close with a T type nut 421 mutual bolts, the suitable weight of this T type tool, drawdown in water tank, the weight of nut can drive transfer valve and descend automatically, and so only need to rotate T type nut, can change the length of valve rod, short, and the position that the valve rod of change transfer valve is driven by secondary ball float, reach the practical design that supplies water and switch, and with transfer valve and the separated setting of secondary ball float, have the lifting that makes transfer valve, can be by end face 300 thrusting actions of secondary ball float, and can avoid by secondary ball float, if when deflection is arranged, transfer valve is caused harmful effect, reaches real switching advantage smoothly.

Characteristics of the present utility model:

1, utilizes a secondary ball float that is located at water inlet device to control switching mechanism, have the smooth and easy advantage of ascending, descending.

2, adopt clastotype between valve rod and secondary ball float again, have the ascending, descending of the valve rod of order and be not subjected to secondary ball float lift rail The mark impact, and can move fast with certain.

3, transfer valve and the valve rod in the switching mechanism is formed in one, and assembly is fast and easy very.
