Description

Single-gun-type tap temperature display unit

The utility model is about a kind of single-gun-type tap temperature display unit

Even the supply of tap water as power supply, education national dividend, always is a big index of weighing social development, after all, this water that is concerning people's daily life, it is very wide that it involves aspect, so the area of common no water service, it promptly is an example that the infectious diseases class keeps pouring in.

And tap water go out water management, be by means of water tap, water tap commonly used is revolving, affects the size of internal valve member with the control water output by knob, believes that this is the known examples of people.

Because normal water, the cold water that must possess washing or drink, and the hot water of shower usefulness are so in the bathroom, must possess the supply of cold water and hot water basically.And in recent years, along with the raising of national income, the kitchen has hot water service, and finding is also arranged more.

And cold a, hot water tap is used in the supply of this hot and cold water traditionally respectively, mixes after water outlet again.Certainly, this must operate two water taps, begins to reach the effect of required warm water, rather inconvenience in operation.

Now, the people has been arranged, that is hot and cold water mixes at once in water tap, and via single water outlet water outlet, and its cold and hot water outlet can be adjusted by control handle, to reach the water temperature of people's expectation at the so-called single-gun-type water tap of exploitation.

In fact, the complete such sensation of the water temperature of this mode, so the user must be by the sensing of human body (being generally hand) to ask for suitable water temperature, certainly, even this mode is for the individual, also non-wise policy, because partes corporis humani's part is different to temperature susceplibility, user's family population often still more, that is spread all over the elderly, even in, young people child baby etc.

So existing dealer is developed and to have the single-gun-type water tap that temperature shows, and also is used in the external person of restaurant, also there is minority to obtain the case of patent, as U. S. Patent the 4th, 682,626 and 4,968, promptly be for No. 152.

Above-mentioned prior art, its maximum disappearance promptly is that structure is complicated, and must change the element of present single-gun-type water tap, so exploitation is high with manufacture cost, embarrasses ordinary consumer to accept.

In view of this, the claimant is based on for many years observation, and once obtains the fact your office has checked and approved the patent of turning off the tap, and concentrates on studies, and then develops and this case it " single-gun-type tap temperature display unit ".

For further disclosing the concrete technology contents of this case, at first see also diagram.Wherein, Fig. 1 is known single-gun-type water tap sectional drawing, and Fig. 2 A and 2 B are the generalized section (when closing) of this case, and Fig. 3 is the generalized section (during unlatching) of this case, Fig. 4 is the circuit diagram of this case, and Fig. 5 is the temp-sensitive apparatus conspectus.

As shown in Figure 1, it is known single-gun-type water tap, be to drive a control lever 20 and then cross running shaft 30 and drive connecting plate 40 with leader 10, and be to set a leakproof rubber ring 60 and be interlock state each other in connecting plate 40 and the moving sheet 50, so when handle 10 when moving up and down, may command water-outlet quantity then, and when turn, then control lever 20 and drive moving sheet 50 rotations, and be the mixing preparation of hot and cold water.

The utility model is to continue to use this known technology working method and add to put temperature indicating device, shared in the hope of existing element.

As Fig. 2,3,4, shown in 5, be feature part of the present utility model, comprise that leader 1, a control lever 2, a running shaft 3, a connecting plate 4, a moving sheet 5, a leakproof cushion rubber 6 and a temp-sensitive apparatus 7 combine.

Wherein, handle 1 is different from the known technology part, is to form one chamber 11 hollowing out on the face, and has a line hole 12 and a switch hole 13 in the bottom, and the top has a lid 14 to give driving fit.

Control lever 2 is a known technology, and it is linked between handle 1 and the connecting plate described later 4 thinks start.Running shaft 3 is different from outside the known technology, is to have in the axis body running through of a perforation 31, passes through for temp.-sensing wire 74 described later.

Connecting plate 4 is as described above running shaft 3 also, and corresponding to aforementioned penetration hole 31 places, one is extended a slice post 41, and basic central authorities have running through of a post hole 411, and this sheet post 41 is to extend in the hot and cold water mixing chamber.

Moving sheet 5 is known technology with leakproof cushion rubber 6, its role is to control water yield size and hot and cold water mixed proportion.

Temp-sensitive apparatus 7 be comprise a battery 71 that is fixedly arranged on switch hole 13 in the aforementioned handle 1 (because of the drawing angle not shown), and the temperature sensitive switch 72 and that links this battery 71 is embedded at the liquid crystal display 73 in the chamber 11, it also is linked to a temp.-sensing wire 74 ends, and end is and is placed in the interior temperature-sensitive terminal 75 in aforementioned post hole 411 before this temp.-sensing wire 74.

Please consult Fig. 3 and Fig. 4 again, this temperature sensitive switch 72 is to be made of two pole pieces 721 that separate, and mat handle 1 when upwards pulling two pole pieces touch the formation path, and press down when closing when handle 1, then be that two pole pieces 721 just separate formation and open circuit.

This case is when implementing, Fig. 2 is the state when closing, when making progress pulling handle 1 as Fig. 3, as shown by arrows then hot and cold water (or cold water or hot water) promptly via water inlet and enter in the mixing chamber and flow out through water outlet again, and meanwhile, because temperature sensitive switch 72 is an on-state, so the water temperature that is recorded in mixing chamber by temperature-sensitive terminal 75 is to be shown in liquid crystal display 73 moment.And this moment rotating handles 1, promptly can tune to suitable temperature, when handle was pulled for 1 time, then water outlet was closed and temperature sensitive switch 72 also forms and opens circuit, and is like this, can avoid the waste of electric power.

In fact, this case can be obtained the demonstration of temperature via the improvement of existing element, and it removes to have greatly in commercialization and benefits, processing and assembling and folding separate or battery replacement simple, so have value on the industry.

This case those disclosed herein are a kind of of preferred embodiment, and the scope of patent protection of this case is not all taken off in Ju Bu change or modification and come from the technological thought of this case and be easy to the person of knowing by inference by the people who has the knack of this technology such as.

In sum, no matter this case is with regard to purpose, and means and effect show that all it obviously is different from the known technology feature, and it at first creates and close in practicality, also all meets the patent requirement of model utility.
