Embodiment Construction
[0028] The technical solution of the present invention will be described in detail below.
[0029] figure 1 -2 is a structural schematic diagram of the floating ball in the present invention. Such as figure 1 As shown in -2, the float level switch includes a float, including a first half and a second half, and the first and second halves form the float after hot-melt molding.
[0030] The first and second halves respectively include spaced-apart hot-melt main welding layers 3 and hot-melt auxiliary welding layers 4, and a plurality of hot-melt main welding layers 3 and hot-melt auxiliary welding layers 4 are arranged between Blocking blocks 5, preferably, there are at least three blocking blocks 5, so as to separate the peripheral hollow body 6 in sections, and the peripheral hollow body 6 is formed on the main hot-melt welding layer 3 and the auxiliary Solder the cavity between layers 4. The switching device (not shown) of the float level switch is placed in the inner cav...

The invention relates to a float ball of a float ball liquid level switch. The float ball comprises a first half part and a second half part, wherein the first half part and the second half part form the float ball after being subjected to hot-melt molding; and the first half part and the second half part comprise a main hot-melt weld layer and an auxiliary hot-melt weld layer separated from each other respectively, and a peripheral hollow cavity isolated from the exterior of the float ball is arranged between the main hot-melt weld layer and the auxiliary weld layer. The float ball has the following advantages: the float ball is provided with the main weld layer and the auxiliary weld layer which have a double leakage-proof effect on the float ball by means of a hot-melt welding mode, so that the housing of the float ball is sealed completely without water leakage or air leakage phenomena, and has a beautiful appearance; the main welding strength and splitting strength of the float ball formed by hot melting can be larger than 100 pounds, and the welded float ball can not split at a welding edge, which is much better than thhhe traditional sealing process; and the structure formed by hot melting facilitates large-scale rapid manufacturing on a production line, and is low in manufacturing cost, high in manufacturing efficiency and favorable for popularization.
Description
technical field [0001] The invention relates to a floating ball, in particular to a floating ball for a liquid level switch of the floating ball. Background technique [0002] The hot-melt welding process is a plastic sealing welding process with simple procedure and convenient use, which is widely used in sealing processing of various plastic mechanical parts. [0003] Although the industrial process of hot-melt welding is simple and widely used, at present, this method has not been used for product sealing in the field of float level switches, and other sealing methods are still used, such as: injection molding, glue point bonding, Use the principle of pressure difference, etc. In the prior art, injection molding is often used to seal the float level switch. This method usually has complicated processes, high manufacturing costs, low sealing performance, and low production efficiency. Contents of the invention [0004] The object of the present invention is to provide ...
