Abstract

The utility model discloses an improved structure of a tap, which comprises a shell body, a constant temperature valve core and a water outlet switch, wherein the shell body is provided with a cold water inlet, a hot water inlet and a constant temperature water outlet; a cold water channel which is communicated with the cold water inlet, a hot water channel which is communicated with the hot water inlet and a water outlet channel which is communicated with the constant temperature water outlet are arranged in the shell body; the cold water channel and the hot water channel are integrally generated with the shell body; the water outlet channel and the shell body are manufactured separately, and the two are fixedly connected by welding; a large gap is formed between the water outlet channel and the shell body to form a mixing chamber; and one end of the mixing chamber is communicated with the constant temperature valve core, and the other end thereof is communicated with the water outlet channel through the water outlet switch. The improved structure of the tap overcomes the problems of a traditional tap, and the shell body of the tap is characterized by simple structure, low manufacturing cost and high finished product quality.

Description

A kind of structure-improved of tap

Technical field

The utility model relates to the structure-improved of a kind of tap, particularly a kind of tap.

Background technique

At present, tap is generally by housing, constant temperature valve core and effluent switch are formed, its middle shell is provided with cooling water inlet, hot water inlet and thermostatted water water outlet, be provided with the cold water channel that is communicated with cooling water inlet in the housing, hot water channel who is communicated with hot water inlet and the exhalant canal that is communicated with the thermostatted water water outlet, in use, cold water is entered through cold water channel by cold water outlet and flows to constant temperature valve core, hot water is entered through the hot water channel by the hot water mouth and flows to constant temperature valve core, and flow to the cold of constant temperature valve core, hot water carries out temperature adjustment to be mixed, after effluent switch, exhalant canal is flowed out by water outlet realizes constant-temperature effluent.

In above structure, be arranged on the cold water channel in the housing, hot water channel and constant-temperature effluent passage all generate with the housing one, other parts of removing in the whole housing behind above-mentioned three passages all are entity structures, this structure setting causes a large amount of consumptive materials, make the manufacture cost of tap very high, simultaneously also make shell construction complicated, and at present, the case material of tap still is to adopt zinc alloy greatly, metallic material such as Cuprum alloy are also made by sand casting process, therefore, the sand mold mould that complicated shell construction will make housing make is complicated, not only give to build and bring difficulty with the demoulding, simultaneously in manufacture process, also be easy to occur sand holes and pore, make the defect rate of making than higher.

The model utility content

At the problems referred to above, the utility model has designed a kind of structure-improved of tap, and that its housing has is simple in structure, low cost of manufacture, characteristics that end product quality is high.

For achieving the above object, the utility model is by the following technical solutions:

A kind of structure-improved of tap, comprise housing, constant temperature valve core and effluent switch, its middle shell is provided with cooling water inlet, hot water inlet and thermostatted water water outlet, be provided with the cold water channel that is communicated with cooling water inlet in the housing, hot water channel who is communicated with hot water inlet and the exhalant canal that is communicated with the thermostatted water water outlet, it is characterized in that: described cold water channel, hot water channel and housing one generate, described exhalant canal and housing split are made, both are fixed together by welding, have very big gap between exhalant canal and the housing and form mixing chamber, one of mixing chamber is communicated with constant temperature valve core, and the mixing chamber other end is communicated with exhalant canal by effluent switch.

In above structure, the cold water channel, hot water channel and the housing that are arranged in the housing are that one generates, and exhalant canal and housing are split manufacturings, both are fixed together by welding, this structural design has played the effect of simplifying shell construction, is convenient to the sand mold manufacturing of housing, not only gives to build with the demoulding to bring convenience, also reduce simultaneously sand holes and the pore that in manufacture process, occurs, made the yield rate of making improve greatly.

In addition, have very big gap between exhalant canal and the housing and form mixing chamber, this structure setting can significantly reduce the manufacturing consumptive material of housing, and the manufacture cost of tap is reduced.

Description of drawings

Fig. 1, perspective view of the present utility model;

Perspective view after Fig. 2, the utility model housing are analysed and observe.

Embodiment

As illustrated in fig. 1 and 2, a kind of structure-improved of tap, comprise housing 1, constant temperature valve core 2 and effluent switch 3, its middle shell 1 is provided with cooling water inlet 4, hot water inlet 5 and thermostatted water water outlet 6, the exhalant canal 13 that is provided with the cold water channel 11 that is communicated with cooling water inlet 4, the hot water channel who is communicated with hot water inlet 5 12 in the housing 1 and is communicated with thermostatted water water outlet 6.

Described cold water channel 11, hot water channel 12 generate with housing 1 one, described exhalant canal 13 and housing 1 split manufacturing, both are fixed together by welding, and have very big gap between exhalant canal 13 and the housing 1 and

form mixing chamber

14,14 1 of mixing chambers are communicated with constant temperature valve core 2, and mixing chamber 14 other ends are communicated with exhalant canal 13 by effluent switch 3.

Above exhalant canal 13 has played the effect of simplifying housing 1 structure with the structure setting of housing 1 split manufacturing, be convenient to the sand mold manufacturing of housing 1, not only give to build to bring convenience, also reduced sand holes and the pore that in manufacture process, occurs simultaneously, make the yield rate of making improve greatly with the demoulding.

In addition, have very big gap between exhalant canal 13 and the housing 1 and form mixing chamber 14, this structure setting can significantly reduce the manufacturing consumptive material of housing 1, and the manufacture cost of tap is reduced.

In sum, the utility model is a kind of structure-improved of tap, and that its housing has is simple in structure, low cost of manufacture, characteristics that end product quality is high.

Claims

1. the structure-improved of a tap, comprise housing, constant temperature valve core and effluent switch, its middle shell is provided with cooling water inlet, hot water inlet and thermostatted water water outlet, be provided with the cold water channel that is communicated with cooling water inlet in the housing, hot water channel who is communicated with hot water inlet and the exhalant canal that is communicated with the thermostatted water water outlet, it is characterized in that: described cold water channel, hot water channel and housing one generate, described exhalant canal and housing split are made, both are fixed together by welding, have very big gap between exhalant canal and the housing and form mixing chamber, one of mixing chamber is communicated with constant temperature valve core, and the mixing chamber other end is communicated with exhalant canal by effluent switch.
