Specific implementation mode

The utility model is further described with specific embodiment below in conjunction with the accompanying drawings, referring to Fig. 1-6：

A kind of anti-scald cold touch tap, including shell 1, shell 1 are equipped with interface of hot water H and cold water interface C, and respectively It is bolted with hot water connector 2 and cold water connector 3；The heat-insulated inner core 9 of engineering plastics material is installed inside shell 1；Specifically see figure 2, thermostatic valve core 8 is combined in 9 upper end installing port of heat-insulated inner core, and lower end is combined with adjusting spool 10, and 1 upper and lower side of shell is set respectively Set the constant temperature hand wheel 4 and adjusting handle 5 for operating spool；In conjunction with Fig. 3 it is found that heat-insulated inner core 9 is in upper end installing port side wall point Not She You cold water hole 9a and hot water hole 9b, hot water connector 2 stretches into the inside of shell 1 and seals cooperation in hot water hole 9b.

In conjunction with Fig. 5 and Fig. 6,9 inside of heat-insulated inner core forms mixing aquaporin X, is formed between heat-insulated inner core 9 and shell 1 cold Aquaporin Y, cold water are flowed by cold water interface C, in the cold water hole 9a that 9 upper end of heat-insulated inner core is flowed to by cold water channel Y；Hot water is then It is flowed by interface of hot water H, directly hot water is sent into hot water hole 9b by hot water connector 2；Cold water hole 9a and hot water hole's 9b difference Coordinate with the thermostatic valve core 8 in 9 upper end installing port of heat-insulated inner core, adjusting hot water or cold water's proportioning, (company can be arranged in heat-insulated interior core inner It meets the hot water flux of hot water hole, connect the cold water runner of cold water hole, can also directly pass through cold water hole 9a and hot water hole 9b and perseverance Warm spool 8 coordinates), mixing water flows into the mixing aquaporin X inside heat-insulated inner core 9；Aquaporin X is mixed after adjusting spool 10 Being divided into flow direction shower outlet and flowing to two branches that shower exports (can also only set a branch, such as only shower outlet Or shower outlet, adjusting spool is for adjusting uninterrupted)；Two outlets are bolted with shower bath adapter 6 and shower head connector respectively 7, two connectors are radially pierced by shell 1.In conjunction with Fig. 3,9 upper end of heat-insulated inner core is provided with annular seal groove 9c, it is O-shaped for coordinating Circle, avoids revealing；In conjunction with Fig. 2 and Fig. 6, it is combined with core retainer plate 11 in 9 lower end of heat-insulated inner core, adjusting spool 10 is fixed on core retainer plate 11 Interior, core retainer plate 11, which is spirally connected, to be fixed on shell 1, and is blocked in tail portion and have pressure cap 12, for by cold water channel Y and adjusting spool 10 every It leaves, to make mixing water be flowed out from adjusting spool 10, flow to shower bath adapter 6 or shower head connector 7.

Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this It encloses, therefore：The equivalence changes that all structures, shape, principle according to the utility model are done, should all be covered by the protection of the utility model Within the scope of.
