The accompanying drawing explanation
Fig. 1 is the structural representation of the water dispenser of a kind of anhydrous auto-breaking of the utility model;
Fig. 2 is the operation principle schematic diagram of the water dispenser of a kind of anhydrous auto-breaking of the utility model;
Label in figure is respectively:
1, bucket; 2, control tank; 3, delivery port;
4, relay; 5, heating power supply interface; 6, singlechip controller;
7, heater; 8, pressure sensor; 9, manual heating switch;

The specific embodiment
The specific embodiment below in conjunction with accompanying drawing to the water dispenser of a kind of anhydrous auto-breaking of the utility model elaborates.
Referring to Fig. 1, the structural representation of the water dispenser of the anhydrous auto-breaking of the utility model.
A kind of water dispenser of anhydrous auto-breaking comprises that bucket 1, that a housing 10, is arranged on described housing 10 tops is arranged in described housing 10 and the control tank 2, the delivery port 3 and be connected with control tank 2 that are communicated with described bucket 1 are arranged on the heater on described control tank 2.Described water dispenser further comprises a pressure sensor 8, a singlechip controller 6 and a relay 4.
Wherein, described pressure sensor 8 is arranged on described control tank 2, in order to detect the hydraulic pressure of described delivery port 3 positions, and the hydraulic pressure information of collection is sent to described singlechip controller 6 after signal amplification and A/D conversion.In the present embodiment, described pressure sensor adopts FJ21 type sensor.
Described singlechip controller 6 is arranged in housing 10, and is connected with described pressure sensor 8, in order to receive described hydraulic pressure information, and compares with a pre-set threshold value, to control described relay 4 closures according to comparative result or to disconnect.Described single-chip microcomputer adopts Atmega16 type single-chip microcomputer, has the characteristics of high-performance, low-power consumption.
The heating power supply interface 5 that described relay 4 and is arranged in described housing 10 is connected, and in order to when described relay 4 is closed, described heating power supply interface 5 is disconnected, and when described relay 4 disconnects, described heating power supply interface 5 is connected.In the present embodiment, described relay adopts electromagnetic relay.
Continue shown in Figure 1ly, described water dispenser also comprises a manual heater switch 9, and described manual heating switch 9 is connected with described heating power supply interface 5 by a heating power supply line respectively, and passes through a power line and be connected with described heater 7.Described manual heating switch 9 is controlled by the user, if water dispenser need to be used heating function manual heating switch 9 to be opened, otherwise the used time is not closed manual heating switch 9.
Below will further illustrate the operation principle of water dispenser:
Shown in Fig. 2 and Fig. 1, described pressure sensor 8 detects the hydraulic pressure of described delivery port 3 positions, and the hydraulic pressure information of collection is sent to described singlechip controller 6 after signal amplification and A/D conversion.Described singlechip controller 6, after receiving this hydraulic pressure information, compares with a default threshold values, and does corresponding processing according to comparative result again.This threshold values is to be set by the manufacturer of water dispenser.If when the hydraulic pressure of delivery port 3 positions is less than default threshold values, described singlechip controller 6 sends a signal of telecommunication, makes relay 4 closures, thus the working power of cut-out and water dispenser, otherwise relay 4 in disconnecting shape, makes the heating power supply interface of water dispenser in on-state always.
Again add water in bucket 1 after, described pressure sensor 8 detects the variation in water pressure of 3 positions, the mouth of a river, and transfers hydraulic pressure information to the signal of telecommunication, after signal amplification and A/D conversion, is sent to described singlechip controller 6.Described singlechip controller 6 compares this signal and default threshold values, and then judges.If this signal is within normal range (NR), hydraulic pressure is normal, and described singlechip controller 6 sends a signal of telecommunication to relay, thereby the heating power supply interface is connected, otherwise relay is not done any action.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
