Embodiment
Below the technical solution of the utility model is elaborated.
Fig. 1-2 is the structural representation of the ball float in the utility model.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 isolated hot melt master weld layer 3 and the auxiliary weld layer 4 of hot melt respectively, between described hot melt master weld layer 3 and the auxiliary weld layer 4 of hot melt, 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 weld layer 4.The switching device (not shown) of described floating-ball level switch is placed in the auxiliary weld layer 4 formed internal cavities of described hot melt.The auxiliary weld layer 4 of described hot melt master weld layer 3 and hot melt is 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 the auxiliary weld layer 4 of hot melt.
The auxiliary weld layer 4 of described hot melt be distributed on the ragged edge of described floating-ball level switch and described stopper 5 on, thereby it is outside and described peripheral cavity body 6 is isolated, the gas leakage segmentation of leaking local in the peripheral cavity body 6 can be cut off after auxiliary weld layer 4 welding of described hot melt, thereby the gas leakage of leaking that prevents described part is flowed in whole peripheral cavity body 6, therefore can further strengthen the hot melt sealing effectiveness of ball float.
