Abstract
The utility model provides a novel level sensor including sensor body, base, install in electron tube, the pipette of this urea sensor main part bottom and return the liquid pipe, is provided with the base on the sensor body, the base is provided with filter equipment with pipette intercommunication, level sensor below, and filter equipment includes filter screen and filter, the filter screen part covers the pipette and returns the liquid pipe, the filter sets up in the pipette, goes back to liquid pipe and electron tube bottom. Through divideing into filter equipment filter screen and filter, the filter is integrated into one piece's duroplasts material, has not only guaranteed the efficient filter effect but also practiced thrift the cost, can also effectually reduce the use size of filter screen and level sensor's the assembly degree of difficulty.
Description
Technical field
The utility model relates to sensor field, especially a kind of novel, efficient liquid level sensor.
Background technology
Have many liquid level sensors on the market now, but these liquid level sensors are not very perfect in structural design, often can there are some errors in measurement liquid level, these sensor costs are also higher simultaneously, and use cost is larger.
Summary of the invention
The technical matters that the utility model mainly solves is to provide a kind of novel, efficient liquid level sensor.
The technical scheme adopted for the utility model that solves the problem is:
A kind of New Liquid Level Transducer, include and be arranged at the holder on top, the base of bottom and the pipe structure between holder and base, described pipe structure comprises electron tube, pipette and liquid back pipe, and filter is established in described base lower end, filter is provided with some filter bores;
Described pipe structure outside covers screen pack, and described screen pack bottom is connected with base.
Further, the bottom of described pipette, heating pipette and liquid back pipe is provided with the concave surface for assembling screen pack.
Further, described screen pack is fixed by intermediate plate and pipe structure.
Further, described filter and base are connected together.
Further, described filter is provided with the hole supporting with liquid back pipe.
Further, the duroplasts material that is formed in one of described filter.
The beneficial effects of the utility model are:
1. the utility model is by being divided into screen pack and filter by filtration unit, wherein filter is arranged on separately the bottom of liquid level sensor of the present utility model, both the effect of filtration can have been played, play the effect of fixing electron tube, pipette, liquid back pipe simultaneously, simple and practical, change also very convenient.The duroplasts material that filter is formed in one, both ensure that efficient filter effect again saved cost.
2. the groove that with it match of filter screen by arranging in pipette and liquid back pipe, can be highly stable be placed on pipette and liquid back pipe on the surface, such design effectively can reduce the use size of filter screen, both ensure that filter effect again saved material cost.
3. cross filter and be provided with the hole matched with liquid back pipe, effectively avoid because cross the filtering effects of filter and the filter screen working effect of liquid back pipe.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Fig. 2 is the structural representation of a kind of embodiment filter of the utility model.
Fig. 3 is the partial schematic diagram of a kind of embodiment concave surface of the utility model.
In figure: 1 is holder, 2 is liquid back pipe, and 3 is filter, and 4 is screen pack, and 5 is pipette, 6 bases, and 7 is base, and 8 is hole, and 9 is filter bores, and 10 is intermediate plate, and 11 is concave surface.
Embodiment
Refer to Fig. 1, be a kind of embodiment of the present utility model, comprise: holder 1, liquid back pipe 2, filter 3, screen pack 4, pipette 5, electron tube 6, base 7.
Liquid level sensor of the present utility model is when assembling, sensor body and electron tube 6, pipette 5, liquid back pipe 2 are assembled successively, pipette 5 and liquid back pipe 2 install screen pack 4 additional, finally bottom electron tube 6, pipette 5 and liquid back pipe 2, loaded onto filter 3, assemble very convenient, also can carry out member replacing flexibly.
By by screen pack local complexity on pipette 5, liquid back pipe 2, namely can ensure the filter effect to liquid in carrier fluid case, the work efficiency of pipette 5 and liquid back pipe 2 can be ensured again simultaneously.
Refer to Fig. 2, for the utility model crosses the structural representation of filter, comprising: hole 8, filter bores 9.
Filter 3 of the present utility model is the one-body molded design of plastic material.
The size of hole 8 by matching with liquid back pipe 2, the absorption efficiency reduction that because of the obstruction of filter 3 cause of liquid back pipe 2 when withdrawing fluid can be prevented, simultaneously by arranging filter bores 9 on filter 3, namely filter effect can be ensured, dismounting is simultaneously very convenient, greatly reduces assembly difficulty.
Refer to Fig. 3, be the partial schematic diagram of the utility model screen pack, comprise: intermediate plate 10, concave surface 11.
Screen pack fixed by intermediate plate 10, and screen pack is placed in concave surface 11, can realize highly stable placement.
Filter 3 surrounding is provided with some projections, and the base 7 of liquid level sensor is provided with the shrinkage pool matched with the projection of filter 3, when assembling filter 3, directly projection and shrinkage pool one_to_one corresponding can be realized being connected together.
The utility model is by being divided into screen pack 4 and filter 3 by filtration unit, wherein filter 3 is arranged on separately the bottom of liquid level sensor of the present utility model, both the effect of filtration can have been played, also can play the effect of fixing electron tube 6, pipette 5, liquid back pipe 2 simultaneously, simple and practical, change also very convenient.The duroplasts material that filter 3 is formed in one, both ensure that efficient filter effect again saved cost.
The concave surface that with it match of screen pack by arranging in pipette 5 and liquid back pipe 2, can be highly stable be placed on pipette 5 and liquid back pipe 2 on the surface, such design effectively can reduce the use size of screen pack 4, both ensure that filter effect again saved material cost.
Filter 3 is provided with the hole matched with liquid back pipe, effectively avoids because the filtering effects of filter 3 and screen pack 4 working effect of liquid back pipe.
