Description

Water level alarm

Technical field:

The utility model relates to a kind of water level alarm.

Background technology:

In daily life, many times, be easy to when retaining, water be overflowed owing to neglect, cause waste, clear up also very inconvenient, though a lot of water level alarms are arranged on the market, these alarm complex structures, the cost height, maintenance cost is also high, very easily is subjected to external interference during work, all is not suitable for using in daily life.

Summary of the invention:

The purpose of this utility model is in order to overcome above deficiency, and a kind of simple in structure, easy to use, highly sensitive, long service life, water level alarm that cost of manufacture is low are provided.

The purpose of this utility model is achieved through the following technical solutions: a kind of water level alarm, comprise hollow shell, the bottom of housing is provided with a plurality of through holes, be provided with buoyancy tank in the housing, case top is penetrated with a push rod, and the top of push rod is provided with the contact, and the contact places the outside top, the housing top is provided with warning device, and the housing periphery is provided with support.

Further improvement of the utility model is: warning device is made up of contact switch and loudspeaker, and contact switch is connected with loudspeaker, and the electric shock switch places the top, contact.

Further improvement of the utility model is: the top of support is provided with sucker.

The utility model compared with prior art has the following advantages: water infiltrates in the housing by through hole, rising along with water level, buoyancy tank is also along with rising, and the promotion push rod, loudspeaker gives the alarm after contact switch is run in the contact on the push rod, in time reminds people, easy to use, highly sensitive, long service life, cost of manufacture is low.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Number in the figure: 1-housing, 2-through hole, 3-buoyancy tank, 4-push rod, 5-contact, 6-support, 7-contact switch, 8-loudspeaker, 9-sucker.

Embodiment:

In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.

Show a kind of embodiment of the utility model water level alarm as Fig. 1, comprise hollow shell 1, the bottom of housing 1 is provided with a plurality of through holes 2, be provided with buoyancy tank 3 in the housing 1, housing 1 top is penetrated with a push rod 4, the top of push rod 4 is provided with contact 5, contact 5 places housing 1 outside top, and housing 1 top is provided with warning device, and warning device is made up of contact switch 7 and loudspeaker 8, contact switch 7 is connected with loudspeaker 8, electric shock switch 7 places 5 tops, contact, and housing 1 periphery is provided with support 6, and the top of support 6 is provided with sucker 9, can whole alarm be adsorbed on the container side wall by sucker 9, use simple, convenient.

During use, at first water level alarm is adsorbed on the container inside wall of desiring retaining retaining in container, water infiltrates in the housing 1 by through hole 2, and along with the rising of water level, buoyancy tank 3 is also along with rising, and promote push rod 4 risings, when the water level in the container reached the water level of expection, promptly contact switch 7 was run in the contact 5 on the push rod 4, loudspeaker 8 just can give the alarm, timely reminds people, the utility model is easy to use, and is highly sensitive, long service life, cost of manufacture is low.
