Abstract
The invention discloses a temperature adjusting warning device for an engine water tank. The temperature adjusting warning device for the engine water tank is characterized by comprising a temperature photoelectric on-off circuit, an audible and visual alarming circuit and a power supply, wherein the temperature photoelectric on-off circuit is formed by connecting a light emitting head, a relay and a light receiving head in sequence; the audible and visual alarming circuit is formed by connecting a buzzer and a relay; and the power supply supplies power to the temperature photoelectric on-off circuit and the audible and visual alarming circuit through the relay. According to the current situation that a water tank temperature dial indicator exists on an automobile, the temperature photoelectric on-off circuit and the audible and visual alarming circuit are additionally arranged in the invention; the swinging of a pointer of the water tank temperature dial indicator is monitored by means of a photoelectric head; once an upper temperature limit is reached, the buzzer can produce sounds to remind a driver of stopping the automobile and checking the water level of the water tank in time according to the current situation without affecting automobile driving operation.
Description
Technical field
the present invention relates to radiator of car engine field, refer to a kind of engine water tank temperature adjustment alarming device especially.
Background technology
the ubiquitous defect of current vehicle.For this reason, existing commercially existing Overtemperature alarm for car engine, it can, water tank temperature higher in automotive engine operating temperature more than 90 DEG C time send sound and light alarm signal, the working power of point of cutoff ignition circuit automatically, makes engine off simultaneously.Overtemperature alarm for car engine has certain defencive function, but its circuit is complicated, and when running car is on half way up the mountain or in the middle of road, this annunciator automatic train stop likely can cause the accident.
Summary of the invention
the technical problem to be solved in the present invention is to provide that a kind of structure is simple, the water tank temperature increase reminder of automotive engine of safe ready, and it can remind chaufeur to check water tank in time, and don't can affect Driving Operation of Motor Vehicles.
following technical scheme is adopted: a kind of engine water tank temperature adjustment alarming device comprises temperature photoelectricity on-off circuit, sound light alarming circuit and power supply for solving the problems of the technologies described above the present invention; Temperature photoelectricity on-off circuit is by penetrating shaven head, relay, being connected in sequence by shaven head; Sound light alarming circuit is formed by connecting by buzzer phone and relay; Power supply through relay be temperature photoelectricity on-off circuit, sound light alarming circuit powers.
buzzer phone is the piezo buzzer that band helps the operatic tunes.
relay is 12V DC relay.
compared with prior art, the invention has the beneficial effects as follows:
according to the situation current automobile having water tank temperature test indicator, invention increases temperature photoelectricity on-off circuit and sound light alarming circuit, swing by photometer head monitoring water tank temperature indicator gage finger, once reach temperature upper limit, buzzer phone will sounding reminding chaufeur according to situation at that time, timely parking checking cistern water level.This device principle of work is very simple, and need not change automobile circuit greatly, with low cost, only added an auxiliary sound reminiscences, just as reminiscences of fastening the safety belt, itself can not affect Driving Operation of Motor Vehicles.
Accompanying drawing explanation
below in conjunction with drawings and the embodiments, the present invention is further detailed explanation.
fig. 1 is structural representation of the present invention.
Detailed description of the invention
below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described further, as shown in Figure 1,
water tank temperature increase reminder of automotive engine of the present invention comprises temperature photoelectricity on-off circuit, sound light alarming circuit and power supply 1; Temperature photoelectricity on-off circuit is by penetrating shaven head 2,12V DC relay 3 (JRX-13F type), being connected in sequence by shaven head 4; Sound light alarming circuit helps the piezo buzzer 5 of the operatic tunes and relay 3 to be formed by connecting by band; Power supply 1 through relay 3 be temperature photoelectricity on-off circuit, sound light alarming circuit powers.
cH1000 type warning buzzer phone drive integrated circult can be selected when buzzer phone is installed simultaneously; When relay is installed, its two groups of normally open contact parallel connections are used.
below only just type preferred embodiment of the present invention is described, but can not be interpreted as it is limitations on claims.
