ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an automatic quantitative regulator for dissolvent in water tank, more particularly to a structure that can make use of the buoyancy and the discharge status of water in the water tank directly to regulate naturally the release of the dissolvent in predetermined quantity.
2. Description of the Prior Art
The toilet dissolvent long time ago is a dissoluble block sunken into the toilet tank and dissolved naturally. But, since the frequency of using the water tank is variable, it will be caused that the concentration maybe too high or too low. Then, the use status is not uniform to be waste or insufficient. Therefore, all kinds of structure are provided to solve the supply problem of the dissolvent. The conventional structure relates that a dissoluble block or a side of the deposited box of dissolvent block is hung on and fixed at the top edge of the water tank wall with a hook. Then, a release pipe is extended below the bottom of the tank, and a spiral rod inserts through the release pipe. The top and bottom ends of the spiral rod have a bolt circle individually. The top end of the spiral rod connects with a sphere and the bottom end of the spiral rod connects with a float ball. Then, the dissolvent will be release when the spiral rod is moved up and down, wherein the spiral rod is of cross-shape. Someone improves the spiral rod to form a bolt, and a spiral coat connects with the release pipe, then, the bolt part is moved in the spiral coat to release the dissolvent. Moreover, someone improves the style of the hook and the form of the deposited box, or improves the bottom end of the bolt to be of awl-shape. Furthermore, someone improves the bolt of the spiral rod to be two layers or have the upper replenishing box. Even though there have been many forms which have the advantages and disadvantages respectively, it is unable to solve all control problem since there is a certain region to supply the dissolvent. This has been the standard structure. As there is some water in the water tank, it will be supplied continuously until the water is full. But the position must be above the water. If the position is in the water, it will be supplied continuously. For obviating the aforementioned problem and conforming to the practical requirements, the invention proceeds to research and develop.
SUMMARY OF THE INVENTION
The primary object of the present invention is to provide an automatic quantitative regulator for dissolvent in water tank, particularly to use a device to accomplish the function for connecting the components in series. The junction of the upper float ball combines with the junction of the bottom float cone, and the two junctions are joined together bulgy threads. The inner side of the fixing coat is also wedged to the mouth of the jar. The wedge motion is accomplished with a form of flat thread. The wedge motion of the two components is rapid and accurate, and the overall composition is simpler. The component number is also decreased. Thus, the release structure is simpler and more convenient than the conventional one.
Another object of the present invention is to provide an automatic quantitative regulator for dissolvent in water tank, particularly to use the jar itself to accomplish the fixing function. As the equipment in the water tank is different, the present invention uses a hook to fix the jar. Then, the present invention can be a sink-water device.
The yet another object of the present invention is to provide an automatic quantitative regulator for dissolvent in water tank, particularly to the part of the jar can be exposed out of the water to provide an outer replenishing bottle. The jars more than one can be replenished to be suitable for the use in the public occasion.
The further object of the present invention is to provide an automatic quantitative regulator for dissolvent in water tank, more particularly, the connection part between the upper and bottom float balls can be adjusted the clearance for conforming to the requirement of various water tank capacities. Thus, the non-section adjustment can be accomplished with using the joint in a form of flat thread or spiral thread.
The structure of the present invention: an inverted jar is clamped on the standing rod in the water tank. An upper float cone is set in the jar mouth shrunk at the bottom, and a bottom float cone is set outside of the jar mouth. Two float cones are joined together by bulgy threads, and the fixing coat connects with the jar mouth. The two float cones with opposite awl-shape necks are wedged to the aperture formed by inner bulgy circle. The two float cones can be adjusted clearance. When the upper float cone is moved up, the liquid in the jar will flow out gradually. As the upper float cone is moved down, the aperture will be closed. A heavy article is connected with the bottom float cone to accelerate pulling down. Furthermore, a fixed position cup is hooked on the jar, and the bottom of the fixed position cup has a perforated colander.
In order that the present invention may be understood more readily, the following description is given, merely be the way of example, reference being made to the accompanying drawings, wherein:
