Abstract

The utility model relates to a leakage water tester. The technical problem to be solved of the utility model is to provide a leakage water tester with simple structure, convenient manufacture, reliable operation and low price. The leakage water tester is provided with a chassis. The leakage water tester is characterized in that the inner face of the chassis is provided with reinforcing ribs which are crossed mutually and are concave inward. The cross position of the reinforcing ribs is provided with a leakage water detector which is a printed circuit board, an electric pole is provided on the leakage water detector, and a conducting wire is welded on the electric pole. The utility model can be used in various water-treating devices which can generate water leakage phenomenon such as a drinking machine, a water heater, a refrigerating device, etc.

Description

A kind of detector that leaks

Technical field

The utility model relates to a kind of detector that leaks.Be applicable to that various water dispensers, water heater, refrigerator etc. may produce in the water treatment facilities of drainage.

Background technology

In existing water dispenser, drainage is ubiquitous, and especially the frequent inside of direct drinking type water dispenser leaks, and causes chassis ponding, and the consequence of ponding is the phenomenon that possible be short-circuited, and causes unnecessary loss.

Summary of the invention

The technical problems to be solved in the utility model is: a kind of simple in structure, easy to make, reliable operation, the low-cost detector that leaks are provided.

The technical scheme that the utility model adopted is: detector leaks, has the chassis, it is characterized in that having the reinforcement of mutual intersection and indent at the chassis inner face, crossover sites at described reinforcement is equipped with water leak detectors, water leak detectors is a printed circuit board (PCB), be shaped on electrode on it, be welded with lead on the electrode.

Described printed circuit board (PCB) is fixed by the gib screw and the chassis of band O-ring seal.

Described reinforcement is cross one another two, and printed circuit board (PCB) is cruciform.

The beneficial effects of the utility model are: the detector structure of originally leaking is quite simple, be a very thin circuit board in fact, be embedded in the chassis groove in, do not take up room, the position is in the nadir of water dispenser, as long as, just can send warning so some ponding is arranged, or according to the concrete bed hedgehopping that requires to flushing with chassis inner surface; Water leak detectors forms the simplest galvanic circle, so reliable operation; In addition, also has easy to make, advantages of cheap price.

Description of drawings

Fig. 1 is the stereographic map that direction is overlooked on the utility model chassis.

Fig. 2 is the synoptic diagram of side, the utility model water leak detectors position.

Fig. 3 is the partial enlarged drawing of the utility model water leak detectors position.

Embodiment

As shown in the figure, the present embodiment detector that leaks is located at the inside surface central authorities on the chassis 1 of direct drinking type water dispenser, the chassis of the manner is square, on the inner plane on chassis, have two right-angled intersections and inside recessed reinforcement 2, crossover sites at reinforcement is equipped with water leak detectors 3, the water leak detectors of the manner is exactly a criss-cross printed circuit board (PCB) 6 in fact, on two of circuit board relative end points, be shaped on electrode 5, be welded with lead 4 on the electrode, installation method is with the gib screw 7 of being with O-ring seal printed circuit board (PCB) 6 to be fixed on the chassis 1, and the use of O-ring seal is in order to prevent that the ponding in the chassis from spilling from screw fixed hole.

Water leak detectors described in the utility model constitutes the detection loop that leaks by printed circuit board (PCB) 6, electrode 5, lead-in wire 4, when water droplet arrives the chassis, flow to lowest part along the inclined-plane, water runs into two when the electrode, to produce Weak current between two electrodes, this moment, master control borad learnt that this signal just reports to the police and cut off the electricity supply.Water leak detectors can be installed in the lowest part of water dispenser, i.e. the crossover sites of chassis reinforcement (two grooves just), and this position promptly is the minimum position of entire machine, even a spot of like this water also can activate the detector that leaks at an easy rate.The riding position of the described detector circuit board that leaks also can be as required a little bed hedgehopping flush with the inner face on chassis.

In case the water that leaks is dried, the detector that leaks is easy to drying, removes at once and reports to the police.

Claims

1. detector that leaks, has chassis (1), it is characterized in that: the reinforcement (2) that has mutual intersection and indent at the chassis inner face, crossover sites at described reinforcement is equipped with water leak detectors (3), water leak detectors is a printed circuit board (PCB) (6), be shaped on electrode (5) on it, be welded with lead (4) on the electrode.

2. the detector that leaks according to claim 1 is characterized in that: described printed circuit board (PCB) (6) is fixing with chassis (1) by the gib screw (7) of band O-ring seal.

3. the detector that leaks according to claim 1 and 2 is characterized in that: described reinforcement (2) is cross one another two, and printed circuit board (PCB) (6) is cruciform.
