Abstract

The utility model relates to an automatic liquid-level warner; the automatic liquid-level warner is provided with a long tube, both ends of which are enclosed; the both ends are respectively fixed to a dry-reed tube; the two dry-reed tubes are connected with a warning box by lead-out wires, which forms two identical warning circuits; each warning circuit is provided with an LED which is connected in series with each of the dry-reed tubes; a block of music integrated block is connected in parallel in the circuits and a transistor and a buzzer are connected to the music integrated block; an annular float with a magnet is sheathed outside the long tube. The utility model has the advantages that when liquid levels are changed, the automatic liquid-level warner can send out warning for given upper and lower limiting liquid levels to remind people of attention. Especially, the automatic liquid-level warner is used on the hand-press type oil-selling apparatus of a grain store, which can prevent oil leak accident in oil filling process, and can avoid waste.

Description

Automatic liquid-level warner

The utility model belongs to a kind of liquid level autoalarm, and the oil level alarm of the hand oil-vending device use of edible oil is sold by particularly a kind of suitable grain shop.

At present, grain shop sells edible oil and generally adopts the hand oil-vending device, sells the oily preceding elder generation that wants toward the interior oiling of the container of oil-vending device bottom, observes owing to the oil level in the container is inconvenient, when particularly refueling with oil tank, as pays no heed to, and oil will come up, and causes waste; Simultaneously,, be easy to air is drawn up, can not guarantee that client buys the enough deals of oil when the edible oil in container when there is not much left.

The purpose of this utility model provides a kind of liquid level alarm device, puts it in the liquid, can be in the change upper limit that sets in advance or send warning in limited time down of liquid level, and reminds people is noted, takes the necessary measures, and avoids loss.

The purpose of this utility model is achieved in that in the long tube of closed at both ends, each fixes a tongue tube position of setting in two ends, two tongue tubes connect with the warning box by extension line, two tongue tubes constitute two identical warning circuits with the warning box, there is a light emitting diode to be connected in series in each warning circuit with tongue tube, a music-integrating block is attempted by in the circuit, and music-integrating block connects a triode and a hummer, and two warning circuits are connected with electric battery; The outer annular float of suit of long tube is fixed with magnet on the float.

Principle of work: during use, long tube is inserted in container, when injecting fluid, float rises with liquid level, when float rises to the upper end desired location, magnet on the float is with contact adhesive in the tongue tube of upper end, and a warning circuit is connected, and a light emitting diode and a hummer on the warning box send light and acoustic alarm; When liquid level descends, float descends thereupon, and when float dropped to the lower end desired location, the magnet on the float was with contact adhesive in the tongue tube of lower end, another warning circuit is connected, and another light emitting diode on the warning box and another hummer send light and acoustic alarm.

For better difference two ends liquid level warning, two diodes show two kinds of colors respectively, and two hummers send the different sounds or music respectively.

Advantage of the present utility model: be placed in the liquid, when liquid level changes, can send warning to the upper limit or the bottom limit level of prior setting, reminds people is noted, takes the necessary measures, especially on the hand oil-vending device of grain shop, use, run oil in the time of effectively preventing oiling, avoid waste, oil mass stops to sell oil seldom the time, avoid bringing loss, improve service quality to client.

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model circuit theory diagrams.

Fig. 3 is that the utility model uses synoptic diagram.

See Fig. 1-3, obturaged in the two ends of nonmetal long tube 5, fixedly tongue tube 4,8 bonds on the upper and lower end desired location in long tube 5, two tongue tubes 4,8 are drawn outside the long tube 5 by lead, and connect with the warning box 3 of circle, be assembled with two music-integrating block KD1, KD2 in the warning box 3, two light emitting diodes 1,2, two triode DG1, DG2 and two hummer Y1, Y2 and electric battery E.A warning circuit connects as follows: tongue tube 4 is connected in series with light emitting diode 1, and music-integrating block KD1 also connects wherein, connects a triode DG1 and a hummer Y1 on music-integrating block KD1, and is connected with electric battery E; Another warning circuit is same as above, and two warning circuits connect together.Long tube 5 outside suit cork or plastic annular floats 7, magnet 6 of bonding on the float 7.9 is container shown in Fig. 3.

Claims

1, a kind of liquid level autoalarm, it is characterized in that: in the long tube of closed at both ends, each fixes a tongue tube position of setting in two ends, two tongue tubes connect with the warning box by extension line, two tongue tubes constitute two identical warning circuits with the warning box, have a light emitting diode to be connected in series with tongue tube in each warning circuit, and a music-integrating block is attempted by in the circuit, music-integrating block connects a triode and a hummer, and two warning circuits are connected with electric battery; The outer annular float of suit of long tube is fixed with magnet on the float.
