Abstract
The utility model relates to an anti-scald structure of a tap, which comprises a tap body, wherein a cold/hot water inlet, and a water outlet connected with a water outlet terminal are arranged on the tap body (1). The anti-scald structure of the tap is characterized in that a check valve is arranged on the cold/hot water inlet of the tap body, so that the check valve can seal the cold/hot water inlet as long as a water outlet switch is closed, the condition that hot water is continuously gathered in a water-mixing transverse pipe of the tap body is avoided, and the aim of scald prevention is achieved. Moreover, because of the function of the check valve, the backflow of residual water in a waterway of the tap after the switch is closed can be prevented, and the sanitation and the safety of the water quality of a water source are ensured.
Description
Technical field
The utility model relates to the sanitaryware field, is meant a kind of anti-scald structure of tap of shower set especially.
Background technique
The tap of existing shower set mixes cold that the water transverse tube is provided with, hot water intake, all be directly with cold, in the mixed water cavity in the hot water inlet tube, the water that mixes back formation uniform temperature is communicated with water outlet to outlet terminal by effluent switch control again, close effluent switch in the use as after temporary transient or the shower end, can make cold, the hot water aggregate is in transverse tube, because mostly transverse tube is metal material and makes, therefore quite high in transverse tube temperature near the water inlet of hot water place, the user causes scald easily as touching because of carelessness, and high temperature also damages the thermostat valve that mixes in the water transverse tube easily, influence the sensitivity of thermostat valve, unfavorable use.
The model utility content
In view of this, the purpose of this utility model is to provide a kind of anti-scald structure of tap, can improve the aforementioned deficiency of commonly using structure, uses safer.
For reaching this purpose, the technical solution of the utility model is:
A kind of anti-scald structure of tap includes faucet body, and this faucet body is provided with hot and cold water intake and connects the water outlet of outlet terminal, and it is characterized in that: the hot and cold water intake in this faucet body is provided with safety check.
Described safety check mainly comprises valve pocket, valve seat, valve rod and spring, this valve pocket middle part is provided with trepanning, the below then is provided with hollow part and is formed with limited step, this valve seat is provided with through hole, this valve pocket sealing is in conjunction with valve seat, and this valve rod to be a body of rod and an end be shaped diameter end big than the valve seat through-hole diameter, this valve rod wears the trepanning of valve pocket and is located at valve pocket and valve base chamber in conjunction with spring, and is just matched with the through hole of valve seat in the end of valve rod.
The end of this valve rod can be set as cambered surface.
The utility model adopts such scheme, as long as close effluent switch, this safety check can seal hot and cold water intake, stop hot water constantly to accumulate in the mixed water transverse tube of faucet body, reach the purpose of anti-scald, and close the surplus aqueous reflux in the leading water route, back because the effect of safety check also can prevent switch, guaranteed the safe and sanitary of source quality.

Embodiment
As shown in Figure 1, 2, be the anti-scald structure of the utility model tap, it comprises a faucet body 1, is divided into the effluent switch 2 and the mixed water thermostat valve 3 at faucet body 1 two ends.
Be provided with water channel and the corresponding water outlet 13 that is communicated with the hot and cold water intake 11,12 on the body 1 and connects outlet terminal in this faucet body 1, form respectively intake water route and water outlet water route.
Key of the present utility model is: each sealing is provided with safety check 4 on the hot and cold water intake 11,12 of faucet body 1.The structure of this safety check 4 and of the prior art similar, as shown in Figure 3, it mainly comprises a valve pocket 41, a valve seat 42, a valve rod 43 and a spring 44; This valve pocket 41 is a cylindricality, the middle part is provided with trepanning 411, the below then is provided with hollow part 412 and is formed with limited step 413, this valve seat 42 is provided with through hole 421, these valve pocket 41 sealings are in conjunction with valve seat 42, and the hollow part 412 of valve pocket 41 is communicated with the through hole 421 of valve seat 42, and this valve rod 43 to be a body of rod and an end be shaped diameter end 431 big than the diameter of valve seat through-hole 421, and this end 431 can be set as cambered surface, this valve rod 43 wears the trepanning 411 of valve pocket in conjunction with spring 44 and is located at valve pocket 41 and 42 of valve seats, and is just matched with the through hole 421 of valve seat 42 in the end 431 of valve rod 43.
During use, cooperate shown in Fig. 4,5, opening effluent switch 2 is the conducting outlet terminal, the hydraulic pressure of hot and cold water intake 11,12 is during greater than the elastic force of spring 44, spring 44 is by the roof pressure accumulation of energy, the body of rod that makes valve rod 43 outwards moves and relies on limited step 413 along the trepanning 411 of valve pocket 41, and the hollow part 412 of valve pocket 41 is communicated with the through hole 421 of valve seat 42, and water is entered in the faucet body 1; When closing effluent switch 2 when promptly closing outlet terminal, hydraulic pressure disappears, valve rod 43 is at trepanning 411 retractions of spring 44 at the effect lower edge of restoring force valve pocket 41, and this moment, the end 431 of valve rod 43 just can be sealed the through hole 421 of valve seat 42, can close hot and cold water intake 11,12.
Therefore, as long as close effluent switch 2, this safety check 4 can seal hot and cold water intake 11,12, stop hot water constantly to accumulate in the mixed water transverse tube of faucet body, reach the purpose of anti-scald, and close the surplus aqueous reflux in the leading water route, back because the effect of safety check 4 also can prevent switch, guaranteed the safe and sanitary of source quality.The above only is a preferred embodiment of the present utility model, and the structure of safety check is also not limited thereto, and is all according to claims of the present utility model and the equivalence replacement for it of description institute, all falls in the patent protection category of the present utility model.
