Description
Technical field
The present invention relates to a kind of water dispenser, the water amount detection device of a kind of water dispenser.
Background technology
Also continuing to heat after the water in the bucket in water dispenser is used up is danger close; although present water dispenser typically has power protection loop; also the water for bucket is had not have the protection device of rear dry-fire condition; but these devices all lack degree of accuracy and stability; the associated components of protection device is easily damaged; the protection device not having accurately to control and use steadily in the long term; therefore for this situation; design is a kind of safer; control more accurate, it is possible to the water amount detection device of the water dispenser used steady in a long-term.
Summary of the invention
Wood is invented technical problem to be solved and is to provide safer, to control water dispenser more accurate, that can use steadily in the long term water amount detection device; solution prior art also continues to the associated components of heating, shortage degree of accuracy and stability, protection device after the water in water fountain bucket is used up and is easily damaged, and therefore there is the defect of potential safety hazard.
For solving above-mentioned technical problem, the technical solution used in the present invention includes: is positioned at the substrate bottom water dispenser and is connected with weighing pan, centre is provided with elastomeric element, described weighing pan is additionally provided with the contact of projection, the lower section of contact is provided with stick harness, and the switch being controlled by the movement of stick harness.
Described water amount detection device also includes the water amount detection device being positioned at water storage cylinder of drinking dispenser.
The described water amount detection device being positioned at water storage cylinder of drinking dispenser is magnetic switch, and receives magnetic switch signal and be positioned at water dispenser bottom switch signal and control the pcb board of water dispenser action.
Described contact is wedge that is vertical with weighing pan and that extend downwardly from.
Described contact is one-body molded with weighing pan.
Described substrate is also one-body molded, and weighing pan and substrate are all reserved with the hole slot adapted with each parts.
Described substrate is additionally provided with the occlusion part exceeding weighing pan.
Described weighing pan, substrate link together by connecting post, locking nut and packing ring.
Described elastomeric element is spring or elastic washer.
The invention have the advantages that and beneficial effect:
1, the present invention is coordinated with stick harness by the contact of wedge shape, by traditional press-down type weight induction mode, it is changed into by the way of contact promotion stick harness horizontal displacement activate switch, overcomes traditional approach and cause the often damage of switch, the elastic force of spring to be difficult to control to the shortcoming that can not weight be accurately sensed caused by the unexpected stress of spring control switch Chang Yinwei weighing pan.Make the water dispenser can be safer, reduce the fault rate of water dispenser, and production cost is low；
2, the present invention is by the Weight detecting device bottom water dispenser and the condensate tank of dehumidifier in water butt, makes water yield detection more accurate, more many one layer of protections during for preventing water dispenser from dry combustion method occur so that the use of water dispenser is safer.

Detailed description of the invention
With reference to Fig. 1, Fig. 2 and Fig. 3 and Fig. 4.The invention provides a kind of water amount detector, be placed in bottom product；It it is bucket 1 on it.This device is made up of substrate 2, weighing pan 4, locking nut 5, packing ring 6, connection post 7, spring 8, stick harness 9, switch 10 and switch cover plate 11, wedge 12.
Weighing pan 4, substrate 3, spring 8, link together through connecting post 7, locking nut 5 and packing ring 6.When not having weight or weight weight not up to design requiring, weighing pan 4, under the effect of spring 8, is pushed to top, and switch 10 is not had pressure, switch 10 to be in free state by stick harness 9.When having weight on weighing pan or weight weight reaches design load, weighing pan 4 is forced into lower section, promotes stick harness 9 to press to switch 10 simultaneously；Switch 10 Guan Bi, provides signal.
Water butt 14 is positioned at product top, and these parts are made up of storage tank 15, sealing ring 16, magnetic switch 17 and tank lid 18.During such as water butt 14 water level less than setting value, the action of magnetic switch, provide PCB signal of water shortage；Being also at closure state as now switched 10, system will be considered that the bottom water yield is enough, and PCB can connect water pump 13, and water pump 13 supplies water to water butt 14, until water level arrives setting value in water butt 14.If water butt 14 hydropenia and switch 10 are off, system will be considered that the bottom water yield is inadequate, and PCB disconnects water pump 13, but can provide signal of water shortage, and prompting user changes water source.
Further, the shapes such as wedge 12 can be made up of the material with certain smoothness cylinder, vertebral body replace.
Further, for preventing the slip of bucket, the substrate 2 both sides bottom water dispenser or side can exceed certain height than weighing pan 4, act the effect of blocking.
Further, connect weighing pan and substrate can be the sponge that spring, elastic washer or hardness are higher.
It addition, in process of production, for easy for installation, substrate 2 and weighing pan 4 one-shot forming respectively can produced, and reserved various hole slots in substrate and weighing pan, the matching form with installing component and part closes respectively, makes easier for installation.
