Brief description of the drawings
Fig. 1 is the principle of work schematic diagram of fish jar fluid level control device in prior art;
Fig. 2 is the cross-sectional schematic of the utility model liquid level sensor one preferred embodiment;
Fig. 3 is the principle of work schematic diagram of the utility model fish jar fluid level control device one preferred embodiment.
Embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Please refer to Fig. 2, is a preferred embodiment of the utility model liquid level sensor, and this liquid level sensor is for detection of the liquid level of water tank, and this liquid level sensor comprises inside and outside two parts.What be positioned at water tank is crystal head assembly 1, is positioned at the light-emitting tube 22, the light receiving tube 23 that comprise shell 21, locate by described shell 21 outside water tank, in addition, in described shell 21, is also provided with control module 24.Described crystal head assembly 1 has the printing opacity projection 11 towards described water tank inside, 11 settings corresponding to described light-emitting tube and light receiving tube of described printing opacity projection.
Comprise the location of inside and outside two parts on water tank wall in order to realize liquid level sensor, in described shell 21, be provided with external magnet 25, described crystal head assembly 1 has and the opposite polarity inner magnet 12 of described external magnet 25.Like this, when the inside and outside two parts of liquid level sensor have identical height, and described printing opacity projection 11 with described light-emitting tube 22 and light receiving tube 23 is corresponding set after, the magnet in the inside and outside two parts of liquid level sensor will attract each other, and whole sensor is fixed on water tank wall.
In the present embodiment, described inner magnet 12 and external magnet 25 all adopt ring-shaped magnet, described crystal head assembly 1 also has an annular casing 13 around described crystal head, and described inner magnet 12 is contained in described annular casing 13, and described external magnet 25 is positioned at described shell 21.
As another kind of implementation, also can make the inner magnet 12 in described crystal head assembly 1 into iron block (not shown).Attraction by external magnet 25 to this iron block, and make to realize the location of the inside and outside two parts of liquid level sensor on water tank.Certainly, also can adopt iron block to replace external magnet 25, and retain the inner magnet 12 in described crystal head assembly 1.These two kinds of modes all can realize utility model object of the present utility model, and can reduce the manufacturing cost of sensor.
Certainly, except adopting the present embodiment magnet to attract each other the mode of fixation of sensor, can also adopt the mode of pasting or fixing and inside and outside sensor two parts are fixed on water tank.
Please refer to Fig. 3, the invention also discloses a fish jar fluid level control device with described liquid level sensor.Comprise liquid level sensor and water supply installation 3, above the structure of described liquid level sensor is described in detail, repeat no more.
Described water supply installation 3 comprises water supply tank 32, is positioned at the submersible pump 31 of described water supply tank, the water pipe 33 that is connected with described submersible pump and can supplies water to water tank T.Certainly, water replanishing device can also adopt other implementation, for example, solenoid valve is set on water pipeline, realizes the supply of moisture content by the mode of braking electromagnetic valve.
The course of work of the present utility model is such, when the liquid level in water tank is during lower than described printing opacity projection 11, the light emitting from light-emitting tube 22, can there is total reflection described protruding 11 with the interphase of air, and through secondary reflection again and arrive light receiving tube 23, now, light receiving tube 23 can send signal to control module 24, control module 24 is indicated water supply installation work, to cistern water supply.In the time that the liquid level in water tank exceeds protruding 11,, can there is not total reflection in described printing opacity projection 11 with the interphase of water, but directly project in water in the light emitting from light-emitting tube 22, light receiving tube does not receive light, and control module instruction water supply installation quits work.
The present embodiment is simple in structure, and sensor stand needn't be set, and also will not extend to fish jar inside by wire.Because sensor is configured to independently two parts, and these two parts are attracted each other by magnetic field and are clamped on fish bowl wall, the adjustment of person easy to use to liquid level.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
