Abstract
The utility model discloses a water supply detection device, including the water pump, the water pump is intake to hold and is connected the raw water, and the circular telegram end is connected, be connected a resistance between the circular telegram end of water pump and the power, the circular telegram of water pump end detects on the wire is connected to automatically controlled board through one. The utility model discloses whether reduced pressure switch, it is normal to determine water supply through the measuring to water pump work electric current size, and this has not only saved manufacturing cost, has avoided the loaded down with trivial details installation procedure of pressure switch in addition, has also avoided the scheduling problem that leaks that pressure switch existed simultaneously.
Description
Technical field
The utility model belongs to supply equipment technical field, particularly one water supply checkout gear.
Background technology
Checkout gear supply equipment generally can be equipped with to detect supply equipment whether normal water supply, in prior art, can setting pressure switch on the outlet pipeline of supply equipment, when supplying water normal, pressure switch can give electric-controlled plate data signal; When nothing supplies water or pressure of supply water is very low, pressure switch can give the data signal that electric-controlled plate one is contrary, and normally whether electric-controlled plate CPU judge to supply water according to data signal, and whether relevant device will enter lack of water duty.The method that this setting pressure switch detects water supply adds the expense of pressure switch in device fabrication cost, and pressure switch is installed loaded down with trivial details, increases integral installation operation.
Summary of the invention
It is simple, with low cost that the purpose of this utility model is to provide a kind of structure, do not need the water supply checkout gear of setting pressure switch.
For this reason, the technical solution of the utility model is: a kind of water supply checkout gear, comprises water pump, and water feeding of water pump end connects former water, and energising end connects power supply; It is characterized in that: the energising end of described water pump be connected a resistance between power supply, the energising end of described water pump detects wire by one and is connected on electric-controlled plate.
The utility model decreases pressure switch, whether normal by judging water supply to the detection of pump working size of current, this not only saves cost of production, and avoids the loaded down with trivial details installation procedure of pressure switch, it also avoid the problem such as to leak existing for pressure switch simultaneously.When supplying water normal, electric current during pump working is larger; When without when supplying water or when pressure of supply water is very low, electric current during pump working is less, whether electric-controlled plate judges to supply water normal according to size of current, whether machine will enter lack of water duty.
Accompanying drawing explanation
Be described in further detail below in conjunction with accompanying drawing and embodiment of the present utility model.
Fig. 1 is circuit connection diagram of the present utility model.
Be labeled as in figure: 1 is water pump, and 2 is former water, and 3 is power supply, and 4 is resistance, 5 for detecting wire, and 6 is electric-controlled plate.
Detailed description of the invention
See accompanying drawing.The present embodiment comprises water pump 1, and water pump 1 water inlet end connects former water 2, and energising end connects power supply 3; The energising end of described water pump 1 be connected a resistance 4 between power supply 3, the energising end of described water pump 1 detects wire 5 by one and is connected on electric-controlled plate 6.
During the present embodiment work, by detecting wire 5 by the reaction of the operating current of water pump 1 to electric-controlled plate 6, when supplying water normal, the operating current of water pump 1 is larger; When without when supplying water or when pressure of supply water is very low, the operating current of water pump 1 is less, whether electric-controlled plate 6 judges to supply water normal according to size of current, whether machine will enter lack of water duty.
Claims (1)
