Abstract
The utility model relates to a water level monitoring device suitable for a blindman, which includes a circuit formed by a power supply, a switch and a loudspeaker, wherein a pair of measuring contacts are connected in series in the circuit, and a fixing device is arranged on a conducting wire connected with the measuring contacts. By virtue of the electrical conductivity of water, two electric contacts are arranged on the circuit of the water level monitoring device, so that when water reaches the contacts, the device is electrified and issues an alarm, so as to remind a user of water level in a container; and the conducting wire on the device is wound on the fixing device, and the user can measure the water level in the container through winding or unwounding the conducting wire.
Description
Technical field
The utility model relates to the Level monitor that a kind of suitable blind person uses.
Background technology
At present, often run into the situation of not knowing whether water has expired in blind person's daily life, perhaps will know the situation how much water is arranged.
Summary of the invention
The purpose of the utility model is that the Level monitor that provides a kind of suitable blind person to use utilizes this device, and when water completely perhaps reached certain water level, the conduction of getting an electric shock gave the alarm, and through touching the projection on the lead, water level what just can be known.
In order to achieve the above object; The Level monitor that the utility model provides a kind of suitable blind person to use; Comprise the circuit that power supply, switch and loudspeaker are formed, in described circuit, be in series with a pair of metering contact, the lead that is connected with metering contact is provided with stationary installation.The lead that is connected with metering contact is wrapped on the stationary installation.Lead between stationary installation and the level measuring contact is provided with the scale projection.
The beneficial effect of the utility model: this device utilizes the electric conductivity of water, and two electric shock points are set on circuit, and when water reached the contact, this device was switched on and alarm is taken place, to remind the position of water in user's container.This device is gone up the lead that is provided with and is wrapped on the stationary installation, is telescopic, can help the user to know the water level in the container.
Description of drawings
Fig. 1 is the structural representation of the Level monitor of the described suitable blind person's use of the utility model.
The circuit diagram of the Level monitor that the suitable blind person that it is trifling that Fig. 2 is the utility model uses.
Embodiment
Below in conjunction with accompanying drawing, the Level monitor that the described suitable blind person of the utility model is used is elaborated.
Fig. 1 is the structural representation of the Level monitor of the described suitable blind person's use of the utility model.This device comprises the circuit that power supply 1, switch 2 and loudspeaker 3 are formed, and on this circuit, is in series with a pair of metering contact 4, and the lead that is connected with this metering contact 4 is provided with stationary installation 5.In the present embodiment, this stationary installation 5 is hook, and the lead that is connected with metering contact 4 is wrapped on the hook, and this lead is provided with scale projection 6, and for example, the distance between two scale projections is two centimetres.
When the blind person uses this device, hook is fixed on the chamber wall, open switch 2; Put into the lead that is wrapped on the hook in the container, when metering contact 4 touches the water in the container, because glassware for drinking water has the characteristic of conduction; Can make the conducting of whole loop; Make loudspeaker 3 give the alarm, to remind the user that this device arrives the water level position, the user obtains the water level position according to the scale projection 6 that is provided with on the lead.Because the lead that is connected on the metering contact 4 is wrapped on the stationary installation 5, uses this device just can measure various heights of water level.
Fig. 2 is the circuit diagram of the Level monitor of the described suitable blind person's use of the utility model.In the figure, power supply 1, switch 2, loudspeaker 3 and metering contact 4 are cascaded through lead.When switch 2 is in closure state, when metering contact 4 touches water, because the conductive characteristic of water makes entire circuit be in conducting state, thereby loudspeaker 3 is given the alarm.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
Claims (3)
