Abstract
A plastic constant temperature tap comprises a casing having a cold water inlet, a hot water inlet and a mixed water outlet, a thermal valve and a switch valve, wherein the thermal valve consists of a thermal valve seat, a thermal valve core and a temperature regulating hand wheel, the switch valve consists of a switch connection seat, a switch valve core and a switch handle, the thermal valve is communicated with the cold water inlet and the hot water inlet respectively through a cold water passage and a hot water passage, and the switch valve core is communicated with the thermal valve core and the mixed water outlet respectively through a mixed passage and an output passage. The utility model is characterized in that: the casing, the thermal valve seat and the switch connection seat are respectively made into separate pieces through plastic injection molding, while the hot water passage and the mixed water passage are respectively connected with a plastic connection pipe and a hollow plastic connection rod between the thermal valve seat and the switch connection seat. On one hand, the structure can ensure that the components are not easy to transfer heat, thereby enabling a low surface temperature of the tap which can not hurt users; on the other hand, the structure is suitable for volume production and assembly. Thus, the utility model can meet the requirements of various consumers with reasonable structure and low cost.
Description
Technical field
The utility model relates to a kind ofly can be responded to water temperature automatically and change the constant-temperature tap that comes control water temperature.
Background technique
For travelling comfort and the Security that improves bathing, various constant-temperature tap has appearred already on the existing market, it comprises the housing that has hot water or cold water's import and mixed water exports, thermostatic valve and switch valve are installed in housing, wherein, thermostatic valve is made up of constant temperature valve seat, the constant temperature valve core that is positioned at the constant temperature valve seat and temperature adjustment handwheel, and switch valve is made of switch joint chair, the switch spool and the switch knob that are positioned at the switch joint chair.During use, set required water temperature by the temperature adjustment handwheel, when the mixing water temperature departs from the water temperature of setting, inductive rod expanded by heating in the constant temperature valve core or meet cold contraction, force the piston in the constant temperature valve core to move, with this size of regulating the hot and cold mouth of a river on the constant temperature valve core, make the temperature of mixing water be in set water temperature all the time.
And at present, above-mentioned tap adopts full steel structure mostly, and promptly integral body forms endoporus stray sand core with copper founding moulding.Because the heat conductivity of copper is good, hot water makes leading surface temperature too high easily, thereby exists the potential safety hazard that injures human body by its heat transfer.Moreover with the tap that sand rotating process is made, yield rate is low, and is inner complicated, and the cost height, also can't be fit to produce in enormous quantities.
Summary of the invention
Technical problem to be solved in the utility model is the present situation at prior art, provides a kind of simple and reasonable for structure, but the plastics constant-temperature tap that the low ease of assembly of cost is produced.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: this plastics constant-temperature tap comprises and has cooling water inlet, hot water inlet, the housing of mixed water exports and thermostatic valve and switch valve, wherein, thermostatic valve is by the constant temperature valve seat, the constant temperature valve core and the temperature adjustment handwheel that are positioned at the constant temperature valve seat are formed, switch valve is again by the switch joint chair, the switch spool and the switch knob that are positioned at the switch joint chair constitute, described constant temperature valve core passes through cold water channel respectively, hot water channel and described cooling water inlet, hot water inlet is connected, described switch spool and constant temperature valve core, then pass through the hybrid channel between the mixed water exports respectively, exhalant canal is connected, it is characterized in that: described housing, constant temperature valve seat and switch joint chair become the split part by plastic injection-moulded respectively, and described hot water channel, the mixing water passage then is respectively to be sealedly connected on that plastics between above-mentioned constant temperature valve seat and the switch joint chair are taken over and the plastics connecting rod of hollow.
As further improvement of the utility model, plastics connecting rod one end of described hollow can stretch in the described switch joint chair, form described exhalant canal between the inwall of the outer wall of this connecting rod and switch joint chair, made overall structure compact more, reasonable like this.
Described temperature adjustment handwheel and switch knob lay respectively at the two ends of housing, and also are to form with the plastics injection, so that reduce whole cost.
Compared with prior art, because housing of the present utility model, switch joint chair and constant temperature valve seat form by the plastics injection, and with plastics take over and connecting rod as passage, therefore one side has guaranteed that each parts does not readily conduct heat, make leading surface temperature low, can not injure the user; On the other hand, adopt this split-type structural, be more suitable in large batch of production and assembling.Thereby the utility model both had the visual effect the same with the metal tap through after the surface treatment, made reasonable integral structure again, and cost is low, thereby can satisfy different consumer demands.
Description of drawings

Fig. 2 be among Fig. 1 A-A to sectional drawing.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, this plastics constant-temperature tap comprises housing 1, thermostatic valve and switch valve, wherein, housing is provided with cooling water inlet 2, hot water inlet 10 and mixed water exports 18, thermostatic valve and switch valve lay respectively in the two-port of housing 1, thermostatic valve by constant temperature valve seat 4, be positioned at the constant temperature valve core 5 of constant temperature valve seat and the temperature adjustment handwheel 3 that is positioned on the housing port is formed, switch valve again by switch joint chair 7, be positioned at the switch spool 8 of switch joint chair and the switch knob 9 that is positioned on the housing another port constitutes.In the present embodiment, above-mentioned housing 1, constant temperature valve seat 4, switch joint chair 7 and temperature adjustment handwheel 9, switch knob 3 become the split part by plastic injection-moulded respectively, and between constant temperature valve seat 4 and switch joint chair 7, be sealedly connected with the plastics connecting rod 6 of plastics adapter 11 and hollow, plastics are taken over 11 and are connected hot water mouth 12 on hot water inlet 10 and the constant temperature valve core as the hot water channel, and the plastics connecting rod 6 of hollow is as the hybrid channel, and it connects the mixing mouth of a river and switch spool water intake on constant temperature valve core.Here, plastics connecting rod 6 one ends of this hollow stretch in the switch joint chair 7, have formed exhalant canal between the inwall of the outer wall of this connecting rod 6 and switch joint chair 7, with coupling cock valve water outlet and mixed water exports 18.
