Abstract

The utility model discloses a constant-temperature faucet structure which comprises an outer shell, a plastic inner core arranged in the outer shell, a water mixing pipe matched in the plastic inner core, a hot water pipe, a temperature control mechanism and a flow control mechanism, wherein the temperature control mechanism and the flow control mechanism penetrate through the outer shell and are matched with two ends of the plastic inner core. The hot water pipe is made of copper and matched with a water supply pipe and the temperature control mechanism respectively by being matched with a water inlet connector and a water outlet connector. The outer shell comprises a front covering shell and a rear end cover matched with the front covering shell. Due to the fact that the copper pipe is directly connected with the temperature control mechanism, the copper pipe is a water inlet passage with independent hot water and the copper pipe is not contacted with the outer shell, the effect of heat resistance of the faucet is achieved. An outer shell structure which does not make contact with water and a full-plastic inner core structure are utilized, a usage amount of the copper is greatly reduced, and material cost is greatly reduced. In addition, due to the fact that components of the constant-temperature faucet structure are few and the hot water pipe is matched with the water supply pipe and the temperature control mechanism by being matched with the water inlet connector and the water outlet connector, assembling is easy and convenient and manufacturing is easy.

Description

A kind of constant-temperature tap structure

Technical field

The utility model is the tap structure about a kind of water outlet device, refers to a kind of constant-temperature tap structure especially.

Background technique

The general structure that adopts full copper of traditional constant-temperature tap, i.e. cast-in-block technological forming, internal cores forms the water route.Because the thermal conductivity of copper is fine, hot water is easy to make in use the surface temperature of tap too high, thereby has the potential safety hazard of scalding the user by its heat conduction.In addition, core casting technique yield rate is low, and the internal structure complexity, then the fabricating cost height is not suitable for large batch of production.

Just notification number having occurred is the CN201037555Y Chinese patent, its disclosed plastics constant-temperature tap, whole tap is to form by 6 working of plasticss, and flow stud shaft, constant temperature stud shaft are contained in stud shaft seat the inside, the left and right sides respectively, and two stud shaft seats connect by a plastic tube, though this scheme effectively reduces cost of material, complex structure, part is various, the die cost height, and assemble complicated quality instability.

Notification number is the CN201884719U Chinese patent, its disclosed novel combination type constant-temperature tap, whole tap is mainly formed by 2 working of plasticss, flow stud shaft, constant temperature stud shaft are contained in stud shaft seat the inside, the left and right sides respectively, and two stud shaft seats connect by seal ring, this patent all adopts plastic material to cross water, for the plastic deformation that prevents the superheated water place need be done abundant and whole being resisted against on the shell, the big expense height of material consumption, and assemble complicated quality and stablize inadequately.

Notification number is the CN201706003U Chinese patent, and its disclosed a kind of constant-temperature tap is to have connected a copper pipe in mixing water outlet place, simplified the structure of core, can reduce reject ratio but the cost height because body still adopts casting in bronze to make, and shell cross water can't be anti-scald.

The present many problems of storage that exist of constant-temperature tap to sum up, this case just produces thus.

The model utility content

The purpose of this utility model is that to improve the ubiquitous surface of present constant-temperature tap hot, the problem that cost is high and a kind of constant-temperature tap structure is provided.

For achieving the above object, solution of the present utility model is:

A kind of constant-temperature tap structure, the plastic core, that it comprises a shell, be arranged in shell is matched with mixed water pipe, a hot-water line of plastic core, and passes shell and be matched with temperature control device and the flow control mechanism at plastic core two ends; Described hot-water line adopts copper pipe and fits into water swivel with water output connector is combined together with water pipe and temperature control device respectively, and shell is to comprise that a front end-cover reaches a rear end cover that cooperates with front end-cover.

Described shell adopts zinc alloy, and the middle part of its front end-cover is provided with the mixed mouth of a river that cooperates for bib nozzle, and two ends form the matching hole that cooperates with flow control mechanism for temperature control device; Rear end cover one end forms the side that curved boom just is covered in front end-cover.

Described plastic core is one to have the straight-bar body of mating cavity, and its two ends form flow stud shaft seat, constant temperature stud shaft seat, forms cold water inlet, water inlet of hot water in the end sidewalls of constant temperature stud shaft seat, and the sidewall at straight-bar body middle part forms and mixes the mouth of a river.

Described mating cavity is a shoulder hole, mixes water pipe and places mating cavity and the mating cavity that is sealed and matched at the step place soon forms one and mixes water cavity and a water chamber stretching.

Described temperature control device comprises temperature handle and the constant temperature stud shaft that is driven by the temperature handle.

Described flow control mechanism comprises flow handle and the flow stud shaft that is driven by the flow handle.

The feed-water end of described hot-water line is engaged on the plastic core and water pipe UNICOM by card by water supply connector; And the waterexit end of hot-water line is engaged in the water inlet of hot water place of plastic core by card by water output connector.

After adopting such scheme, because the utility model is directly connected to temperature control device by copper pipe, and this copper pipe is the hot water path of independently intaking, its not with housing contacts, thereby realized leading anti-scald effect; And adopt the shell mechanism that does not contact water, and overall plastic core arrangement, can reduce the use amount of copper greatly, and then significantly reduce cost of material; Moreover parts of the present utility model are few, and hot-water line is to fit into water swivel to cooperate with temperature control device with water pipe with water output connector, thereby simple and convenient assembly, make easily.
