Description

  The present invention relates to a water-saving device that is attached to a float valve in a water storage tank that discharges wash water such as a flush toilet, and that reduces buoyancy.

Conventionally, as a technique for saving flush water in flush toilets, etc., a weight is added to the float valve that opens and closes the flush water outlet in the water storage tank, and the buoyancy of the float valve is reduced to adjust the closing timing. Things are known.
As a conventional technique, (Patent Document 1) states that “a weight main body formed in a bowl shape, an insertion hole formed in a central top surface of the weight main body, and an outer end of the weight main body from the insertion hole. And a cleaning water discharge valve weight having an incision.
(Patent Document 2) discloses “a water-saving ring crown made of a spiral wire rod seated on the spherical surface of the head of a float valve”.

Japanese Utility Model Publication No. 1-31652 Utility Model Registration No. 3055225 JP 2001-271401 A

However, the above conventional techniques have the following problems.
(1) Since the technology disclosed in (Patent Document 1) passes the lifting member of the float valve from the notch to reach the insertion hole, the weight body is seated on the head of the float valve, so that it can be easily mounted. . However, after the weight is attached to the float valve, the float valve tilts and opens and closes every time the lifting member is operated, and the weight swings vigorously due to the influence of the water flow caused by the water supply and drainage associated with the opening and closing. There is a problem that the lifting member naturally comes off from the notch and the weight often comes off.
(2) The technology disclosed in (Patent Document 2) can be attached by passing the lifting member of the float valve between spiral wires while twisting the water-saving ring crown. However, similarly to the case of Patent Document 1, the spiral wire rod swings due to the tilt of the float valve, the influence of the water flow, etc., and the pulling member may come out naturally between the spiral wire rods. Had. In particular, when the number of windings of the wire is small, this tendency appears remarkably and has a problem that it easily comes off.
(3) If the number of windings of the wire is increased in order to make it difficult to come off, the lifting member of the float valve is attached while passing through the spiral wire while twisting the water-saving ring crown. It had the problem that. In particular, there is a problem that it is troublesome because the work is performed in a narrow water storage tank in which cleaning water is stored.
(4) Since the technology disclosed in (Patent Document 3) includes a bolt-shaped base body and a nut-shaped weight member each having a notch, the weight member is used as the base body after passing through the lifting member. By screwing, it can be prevented from coming off the lifting member. However, since two members, a base and a weight member, are necessary, the number of parts is large, and there is a problem in that productivity in producing a water-saving device is lacking.
(5) There is a problem that it is very troublesome to perform the operation of screwing the weight member onto the base in the narrow water storage tank in which the cleaning water is stored.

  The present invention solves the above-described conventional problems, and can be easily attached to the float valve by inserting the pull-up member connected to the float valve.
