Embodiment
The below is elaborated to technical scheme of the present invention.
Fig. 1-2 is the structural representation of the ball float among the present invention.Shown in Fig. 1-2, described floating-ball level switch comprises ball float, comprises the first half ones and the second half ones, and described first, second half one forms described ball float behind hot melt molding.
Described first, second half one comprises respectively isolated hot melt master weld layer 3 and hot melt auxiliary welding layer 4, between described hot melt master weld layer 3 and hot melt auxiliary welding layer 4, be provided with a plurality of stoppers 5, preferably, described stopper 5 has at least three, thereby peripheral cavity body 6 piecewises are separated, and described peripheral cavity body 6 is formed in the cavity between described hot melt master weld layer 3 and the auxiliary welding layer 4.The switching device (not shown) of described floating-ball level switch is placed in the described hot melt auxiliary welding layer 4 formed internal cavity.Described hot melt master weld layer 3 and hot melt auxiliary welding layer 4 are all around described one week of ball float.Preferably, described stopper can 5 can be integrated with described hot melt master weld layer 3 and/or hot melt auxiliary welding layer 4.
Described hot melt auxiliary welding layer 4 be distributed on the ragged edge of described floating-ball level switch and described stopper 5 on, thereby outside and described peripheral cavity body 6 is isolated, the gas leakage segmentation of leaking of peripheral cavity body 6 interior parts can be cut off after described hot melt auxiliary welding layer 4 welding, thereby prevent the gas leakage of leaking of described part whole peripheral cavity body 6 interior flowing, so can further strengthen the hot-melting sealed effect of ball float.
