Description

[Detailed description of the invention] The invention of the present application relates to a water level adjustment device, and in particular, when pouring water into a bathtub, etc., the desired water level can be easily selected, and when a certain water level is reached, the water injection is automatically stopped. , After the water stops, water will not be released unless other force is applied.
The present invention also relates to an improvement of a water level adjustment device that can reduce noise during water injection.

Conventionally, water level adjustment devices used when pouring water into bathtubs, etc. open and close a valve seat by rotating a valve body (water stop valve) through the movement of a floating lever that moves up and down due to buoyancy. Therefore, due to the structure of the valve chamber, the water pressure during water injection passes through the squeezed part of the valve chamber, which often causes noise due to the friction of the water flow, and the buoyancy of the float causes the lever to move, preventing water injection. Even when the valve is stopped, the screw may be displaced downward when the adjusting device is removed, opening the valve body and dissipating unnecessary water.Furthermore, the structure of the valve chamber is complicated. In many cases, a large number of springs and other parts are arranged inside the valve chamber, and the assembly of the device is laborious and lacks productivity, and failures may occur due to corrosion of the springs and other structural parts. It was a lot.

In view of the above, the inventor of the present application has completed the present invention as a result of research.

Therefore, the purpose of the present invention is to provide a water level adjusting device that can easily select a desired water level.The next purpose of the present invention is to simplify the configuration of the valve mechanism and improve productivity. , by moving the water stop shaft up and down to smooth the closing action of the valve seat.
The purpose of the present invention is to provide a water level control device that can improve the noise caused by the water flow during water injection, and a further object of the present invention is to prevent the lever from moving downward unnecessarily after water injection is stopped. Therefore, it is an object of the present invention to provide a water level adjustment device that does not waste water unnecessarily.

The above objects and other objects and features of the present invention can be understood from the following description.

Next, the structure of the present invention will be explained with reference to the attached drawings showing an embodiment. The concave portion 24 provided at the end of the attached fixing support 23 has a cylindrical shape and several locking shelves 19, 19' are provided on the inner circumferential wall thereof in a stepped manner.
Displacement mechanism 2 provided with vertical grooves 20, 20'
1 is attached to the hollow part of the displacement mechanism 21 toward the outside of the upper edge of the displacement mechanism 21. A cylindrical locking ring 18 having opposing projections 17 and 17' is rotatably and slidably engaged with the locking ring 18, and a valve seat 7 is provided at the lower end in the hollow portion of the locking ring 18.
A valve pipe 9 is fitted with a water inlet 8 connected to a water supply pipe connected to a water source at its upper end, and is integrally fitted into the locking ring 18. has a branched outlet 1, is open at both upper and lower ends, has a hanging part 3 with a fulcrum 2 formed on one side of the outer periphery of the lower opening, and has a locking shelf 4 on the other side. The valve pipes 9 are connected to each other by fitting the upper opening of the connecting pipe 6 with the elastic locking member 5 attached thereto, and windows 10, 10' are provided in the lower part of the connecting pipe 6. A guide tube 11 is installed in the upper hollow part of the guide tube 11, which has a stopper 12 made of rubber or the like attached to the top and a water stop shaft 14 with a bamboo shoot 13 screwed to the tail so that it can move forward and backward. After fitting, one end side of the screw 16 inserted through the windows 10, 10' is pivotally attached to the fulcrum 2 of the hanging part 3 provided on the connecting pipe 6, and a fish-shaped float 15 is attached to the other end side. By rotating the valve pipe 9 on which the locking ring 18 is fitted, the protrusions 17 and 17' of the locking ring 18 are made to correspond to the vertical grooves 20 and 20' of the displacement mechanism 21. Vertical groove 2
0, 20' to displace the protrusions 17, 17' to positions below the appropriate locking shelves 19, 19', and then rotate the valve pipe 9 so that the protrusions 17, 17' are locked to appropriate locking shelves 19, 19', and after selecting and determining the water level, the water tap of the water supply pipe connected to the water inlet 8 is opened, and the water is directed toward the tap body 12 by the valve seat 7. When water is supplied to the outlet, the water stop shaft 14 is easily pushed down by the water pressure, and the water can be sent in one direction of the outlet without resistance. The noise caused by friction can be improved.

Next, as the water level in the tank rises due to water injection, the fish-shaped float 15 attached to the lever 16 floats up while changing its attitude laterally (to the right in the figure) due to buoyancy and is attached to the lever 16. 16 is moved upward, and the protrusion 13 screwed onto the tail of the water stop shaft 14 is pushed upward, and when the water stop shaft 14 is pushed up and reaches the initially set water level, the water stop shaft 14 is moved upward. The water supply is stopped by pressing the stopper 12 provided at the top of the valve seat 7 against the valve seat 7.

At this time, the screw 16 moves upward while pressing the elastic locking member 5 laterally, and when the plug body 12 is pressed against the valve seat 7, it is locked on the locking shelf 4 and locked. Later, unless the elastic locking member 5 is displaced laterally and the screw 16 is removed from the locking shelf 4, the water stop shaft 14
Do not displace it downward.

The fish-shaped float 15 attached to the tail end of the lever 16 rotates only in the direction toward the tail (to the right in the figure) as it rotates upward as the water level rises. In order to prevent the rotation moment from becoming zero, the float 15 is attached to the screw 1.
6, it is desirable to attach the connecting member between the lever 16 and the fish-shaped float 15 in a hanging position slightly inclined to the right in the figure.

In addition, a bamboo shoot 13 screwed onto the tail of the water stop shaft 14 is provided.
By adjusting the degree of protrusion, the screw 1
The movement distance of the screw 16 can be controlled so that the movement of the screw 16 stops when the stopper 12 of the water stop shaft 14 is tightly pressed against the valve seat 7.

Since the invention of the present application has the above configuration, a desired water level can be easily selected by sliding the valve pipe up and down and positioning it via the displacement mechanism.

In addition, the relative position between the valve seat and the water stop shaft has the effect of linearly reducing the friction noise of the water flow during water supply, and as the float rises, the lever pushes up the water stop shaft and stops the water supply. In this case, the screw will be locked to the locking shelf, and there will be no risk of water leaking into the mesh when the device is removed.

Furthermore, since the float is formed in the shape of a fish, and floats while rotating only to one side from its tail, it is possible to create an aesthetic sensation such as being able to observe the swimming state of the fish.

Furthermore, since the structure of the valve mechanism is simple, it is highly productive and has various industrial effects such as reducing the risk of failure.
