New Description: [New Technology Field] This creation is about the floating ball device that floats to the float control switch of different height positions. [Prior Art] For example, the new type of patent (4) M319435 of our country has both a float type liquid level switch and a liquid level switch for the liquid level switch to control the opening and closing of the switch. The floating ball device for the liquid level switch includes a hollow floating ball made of a metal material and a connecting rod made of a metal material and extending backward from the floating ball, wherein the end of the connecting rod is provided with 1 stone to trigger the existing The magnetic switch device of the float type liquid level switch can control the switch to open and close. However, the float ball and the connecting rod of the float device for the liquid level switch are made of a metal material, so that the manufacturing cost thereof is extremely high. The metal float switch is heavier in weight, so the float ball must use a thin metal plate or increase its volume to meet its buoyancy requirements. However, the use of a metal thin plate is likely to affect its function due to insufficient pressure and collision, and increase The float is thicker and thicker, in addition to increasing the cost, the flange or mouth of the mouth to be installed to set up the existing float must also be increased. Therefore, it is not in line with the light, thin and short of modern products: Cost requirements; it can be seen that there are still many shortcomings in the float device for liquid level switches that need to be improved. [New content] In view of the above disadvantages of the float device for a liquid level switch, the purpose of the present invention is to provide a float device for a liquid level switch which is low in cost and easy to use.

I Because the aforementioned float ball and connecting rod have the above structure, the cost can be reduced during manufacture. The X plastic material can be molded by injection molding as long as it is simple to use, and the plastic gravity is lighter than the metal, so the wall thickness of the float ball can be eliminated. Too thin, so it can achieve the purpose of withstand voltage and not afraid of collision, and the pivotal part between the front end of the connecting rod and the end of the connecting rod is also carried by the connecting rod-body forming design. In addition, the magnets placed at the end of the connecting rod can be completely covered by the special structural design, and the liquid is not touched when used, so that it is most suitable for the environment of acid and alkali and does not malfunction. Therefore, the present invention can indeed reduce the manufacturing cost and is easy to use, and can improve the disadvantages of the aforementioned float device for the liquid level switch. [Embodiment] Please refer to the first and second figures.

When the aforementioned float (1〇) and connecting rod (2〇) are made of materials such as plastics that have better buoyancy than metal, the cost of plastic materials is usually Far below the cost of metal materials, the aforementioned floats (1〇) and connecting rods (2〇) also provide the ideal buoyancy, which also helps to save the manufacturing cost of the creation. - Because plastic materials are easy to process, they can It is easy to embed the magnet (23) located at the end of the connecting rod (22), so that the magnet (23) is coated in the plastic material to obtain the effect of protecting the magnet (23), thereby being suitable for use in acid and alkali. The environment does not cause problems due to the failure of the magnet (23) to be destroyed in an acid-base environment. Referring to Figures 3 and 4, the first embodiment of the float device for a liquid level switch of the present invention also includes a float (丨〇A) and a link (2〇A). Further, the aforementioned floating ball (10A) is also a hollow body made of a plastic material, and the aforementioned connecting rod (20A) is also integrally formed of a plastic material and extends from the aforementioned floating ball (1〇) to φ. In addition, the connecting rod (2〇A) also has a connecting rod front end (21A) coupled to the floating ball-(1〇A), a connecting rod end (22A), and a buried end (22A). The magnet (23 A) and a pivoting portion (24a) formed between the front end of the connecting rod (2 1A) and the end of the connecting rod (22A) and having a convex shape. The second embodiment of the present invention is different from the foregoing first embodiment in that the aforementioned link front end (21A) is detachably coupled to the rear end of the aforementioned float ball (1〇A). In a possible implementation of the second embodiment, the rear end of the floating ball (1〇A) is formed with a screwing portion (11A), and the outer peripheral wall of the connecting rod (2〇A) is on the connecting end A thread (25A) matching the aforementioned screw portion (11A) is formed beside (21A). The screwing portion (11A) may be formed as a cylindrical body projecting from the rear end of the floating ball toward the rear of the floating body and forming a matching inner thread (25A) on the inner peripheral wall of the screwing portion (1) A). Thread (15A). The floating ball is also described (the closing can also be formed into a spherical shape. The second embodiment of the present invention is used in the same manner as the first embodiment described above because the front end of the connecting rod (2 1 a) is in the second embodiment. Removably coupled to the rear end of the float ball (1〇A), so the same link 2 can be used with different shapes of the float ball (10A). The same float ball (1〇A) can also be equipped with 0 different length links ( 20A) The user can use the flexible application according to the actual demand. Referring to the fifth figure, in the third embodiment of the present invention, the float (丨〇c) includes a float formed with an opening (13C). The ball body (uc) and a float cover that covers the opening (13C). The float (13C) of the present invention may also have a rectangular parallelepiped shape. The float ball such as the aforementioned third embodiment The (10C) structure can further enable the present application to be used in conjunction with more diverse practical application requirements, and by the separate structure of the aforementioned float body (UC) and the float cover (12C), respectively It is more convenient to manufacture the aforementioned float body (1 ic) and float cover by means of injection molding or the like. The body (12c) is combined to form the aforementioned float (i〇c). Referring to the sixth figure, the fourth embodiment of the present invention is similar to the first embodiment described above, and also has a float (10). And a connecting rod (20) which is different from the foregoing first embodiment in that the fifth embodiment of the present invention sets the aforementioned connecting rod (2〇) to a floating ball support frame (B,), and the floating The ball support frame (B') is composed of two parallel plate bodies 'and the float ball support frame (B|) is integrally formed with the aforementioned flange (A). The aforementioned flange (A) and the aforementioned float ball support The frame (B,) can also be made of plastic material.
