The utility model can be conveniently used to modify the present tap of mechanical switch, the magnetic valve is arranged in the water inlet pipe of the original tap, and the infrared induction device is arrange at the suitable position near the original tap, and the original tap of the mechanical switch is not needed to abandon, thus greatly decreasing the modifying cost.
Description
Technical field
The utility model relates to the opening and closing device of water tap, specifically is meant a kind of external mounted induction switch of water tap.
Background technique
The infrared sensing switch of water tap is very common, is mainly used in public arenas such as public lavatory, hotel, hospital, school, dining room, to prevent that the user is owing to the germ cross infection takes place the contact tap.Infrared sensing switch generally includes solenoid valve, infrared inductor and control circuit board, infrared inductor produces signal by human body to ultrared obstruct, control circuit board is according to the break-make of this signal intelligent ground control electromagnetic valve, for example, after receiving the signal that infrared rays intercepted, open solenoid valve, after through a preset time, automatically close solenoid valve, or when infrared rays is not intercepted, be that people use to wash one's hands or wash one's face and finish, during hand leaving water tap, close solenoid valve automatically.
Above-mentioned solenoid valve, infrared inductor and control circuit board usually and water tap be combined as a whole, promptly inductive water tap if will use this kind water tap, must be removed the water tap of original use, be replaced by new inductive water tap.And the water tap of original a large amount of mechanical switch that adopt if will all be replaced by inductive water tap, not only will spend bigger cost, also will abandon the water tap of original mechanical switch, has caused a large amount of unnecessary wastes.
The model utility content
The utility model provides a kind of external mounted induction switch of water tap, its main purpose is to overcome following problem: when transformation existing machinery formula switch water tap is the inductive switch water tap, must will have the mechanical switch water tap and replace with the inductive switch water tap, mechanical switch water tap originally then goes out of use, cause the reforming cost height, and cause a large amount of wastes.
The utility model adopts following technological scheme: the external mounted induction switch of water tap, comprise electromagnetism water valve, infrared inductor and a Direct box, this electromagnetism water valve is installed in the water supply pipe that is connected with water tap, infrared inductor is installed on by the water tap, the signal output part of infrared inductor is connected with the signal input part of Direct box, and the control signal output terminal of Direct box is connected with the control end of electromagnetism water valve.
The external mounted induction switch of aforementioned water tap, its electromagnetism water valve are electromagnetism barrier film water valve, be provided with in the valve body of this electromagnetism barrier film water valve one with the waterway secondary channel in parallel of this electromagnetism barrier film water valve, be provided with a manual switch in this secondary channel.
The external mounted induction switch of aforementioned water tap, its infrared inductor have two induction windows being located at positive and side respectively.Direct box can carry out intellectuality control according to different induced signals.
By above-mentioned description to the utility model structure as can be known, compare with prior art, the utlity model has following advantage: one, can be advantageously used in transforming the water tap of prior mechanical switch, as long as its electromagnetism water valve is installed in the intake pipe of original water tap, and near the appropriate location that infrared inductor is installed on the former water tap gets final product, and need not discard the water tap of original mechanical switch, greatly reduces reforming cost; Two, under the normal situation of electromagnetism water valve, described hand switch is in closed condition, this secondary channel is blocked, when the electromagnetism water valve breaks down and can't conducting, this hand switch is opened, the secondary channel conducting, then former mechanical switch water tap still can adopt original mechanical switch to control.

Fig. 3 is that A-A among Fig. 2 is to view.
Embodiment
Below with reference to Fig. 1 to Fig. 3 embodiment of the present utility model is described.
With reference to Fig. 1, shown the structural representation that external mounted induction switch that the utility model provides and existing water tap 1 are used.This external mounted induction switch mainly comprises infrared inductor 3 and control box 2 two-part, and this control box is installed in the space of table top 10 belows, can be sealed fixing by screw.This control box 2 is connected with infrared inductor 3 by cable 6.This control box 2 has a water intake 202 and a water outlet 201, and this water outlet 201 is communicated with the intake pipe 11 of water tap 1 by connecting tube 4, and this water intake 202 is connected to the tap water supply pipeline by connecting tube 5.This control box 2 is provided with battery case 21, is the circuit supply in the control box 2.
With reference to Fig. 2, shown the internal structure of described control box 2.Be provided with an electromagnetism water valve 22 in this control box 2, this electromagnetism water valve 22 is connected in the water supply line of water tap 1 by described water intake 202 and water outlet 201.Also be provided with Direct box 24 in this control box, the signal output part of infrared inductor 3 is connected with the signal input part of Direct box 24, and the control signal output terminal of Direct box 24 is connected with the control end of electromagnetism water valve 22.Infrared inductor 3 is intercepted the generation control signal according to infrared rays and is sent to Direct box 24, and Direct box 24 receives the signal of infrared inductors 3, intelligently controls the keying of electromagnetism water valve 22.The circuit of this Direct box 24 is a prior art, can have variedly, and is not innovation main points of the present utility model, no longer describes in detail at this.
With reference to Fig. 3, electromagnetism water valve 22 is an electromagnetism barrier film water valve, electromagnetism barrier film water valve is a prior art, its structure and working principle have detailed description in two utility model patents that the claimant applies in addition, its patent No. and title are respectively: 200320107581.6, and a kind of barrier film water valve of adjustable flow; 200420038805.7, a kind of can be manually opened and the barrier film water valve of can regulate flow.Be provided with a secondary channel 222 in parallel in the valve body of this electromagnetism water valve 22, be provided with described hand switch 23 in this secondary channel 222 with the waterway 221 of this electromagnetism water valve 22.When electromagnetism water valve 22 breaks down, open hand switch 23, secondary channel 222 conductings do not influence the use of former water tap 1.
Above-mentioned infrared inductor 3 has two induction windows being located at positive and side respectively, and Direct box 24 can carry out intellectuality control according to different induced signals.For example: after the induction of positive induction window is boiling water, leave induction range after water promptly close; Side induction window induction back continues water outlet, and positive induction this moment window lost efficacy, and water is closed in the induction back once more, and positive induction recovers proper functioning.
Above-mentioned only is a specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
