Abstract
The invention relates to a water level switch. The water level switch is characterized in that a main water tank and an assistant water tank are connected through a hose to form a communicating vessel; when water in the main water tank decreases, and water in the assistant water tank decreases simultaneously, the weight of the assistant water tank is reduced, the assistant water tank moves vertically under the action of a spring, and a travel switch is in contact with the assistant water tank and moves along with the assistant water tank, so that the purpose of controlling a load is achieved. The water level switch is reasonable and simple in integral structure, so that the production cost is reduced; the travel switch is independent of the assistant water tank and is not soaked in water, so that the service life of the travel switch is prolonged and the water level switch is more convenient and safer to use.
Description
Technical field
The present invention relates to a kind of water level switch, the water level switch especially inside water warming blanket main frame.
Background technology
Existing water warming blanket main frame water level switch is all float water level switch substantially in the market, in float water level switch, magnet is housed, in the pole running through float, dry spring is housed, whole device steeps for a long time in bubble, expand with heat and contract with cold, the generation of incrustation scale, the time has been grown and will stuckly damage, and dry spring can only by faint signal code, not by big current, because this increasing use cost.
Summary of the invention:
The object of the present invention is to provide a kind of structure simple, mechanism does not steep in water and water lev el control is accurate, the water level switch of long service life.
The present invention is achieved in that
A kind of water level switch, it includes: main water box, connecting hose, secondary water tank, fixed lever, travel switch, spring composition, it is characterized in that: the secondary water tank of described water level switch is connected with main water box flexible pipe, the secondary water tank bar that is fixed runs through vertical base and drops on spring from centre, travel switch contacts with secondary water tank, and described secondary water tank can be connected with fixed lever arbitrarily.
Structure of the present invention is simple, main water box and secondary water tank flexible pipe are connected to form linker, when main water box water reduces, secondary Water in Water Tank reduces simultaneously, the weight saving of secondary water tank, secondary water tank moves both vertically under the action of the spring, and travel switch contacts with secondary water tank action thereupon, improves the stability of secondary water tank and the reliability of switch, travel switch and secondary water tank independent agency, and not steep in water thus to extend useful life.
Accompanying drawing explanation
Fig. 1, structural representation of the present invention
In figure: 1-water tank, 2-connecting hose, the secondary water tank of 3-, 4-fixed lever, 5-travel switch, 6-spring.
Embodiment
Execution mode and operation principle is further described below in conjunction with accompanying drawing:
See accompanying drawing 1: it includes: main water box 1, connecting hose 2, secondary water tank 3, fixed lever 4, travel switch 5, spring 6 forms, it is characterized in that: described water level switch main water box 1 is connected with secondary water tank 3 flexible pipe 2, secondary water tank 3 bar 4 that is fixed runs through vertical base and drops on spring 6 from centre, travel switch 5 contacts with secondary water tank 3, main water box 1 and secondary water tank 3 flexible pipe 2 are connected to form linker, after main water box 1 fills water, secondary water tank 3 water of law of connected vessels increases weight simultaneously and increases, secondary water tank 3 vertical downward movement under gravity, travel switch 5 contacts with secondary water tank 3 action thereupon, when main water box 1 main water box 1 water when working use reduces, secondary water tank 3 water of law of connected vessels reduces simultaneously, the weight saving of secondary water tank 3, secondary water tank 3 upward vertical movement under the effect of spring 6, travel switch 5 contacts with secondary water tank 3 action thereupon, thus plays the object of control load.
The present invention is not limited to above-mentioned execution mode, adopts the structure identical or approximate with the above embodiment of the present invention, and the method obtained, all within protection scope of the present invention.
Claims (2)
1. a water level switch, it includes: main water box 1, connecting hose 2, secondary water tank 3, fixed lever 4, travel switch 5, spring 6 form, it is characterized in that: the secondary water tank 3 of described water level switch is connected with main water box 1 flexible pipe 2, secondary water tank 3 bar 4 that is fixed runs through vertical base and drops on spring 6 from centre, travel switch 5 contacts with secondary water tank 3.
2. a kind of water level switch as claimed in claim 1, is characterized in that: described secondary water tank can be connected with fixed lever arbitrarily.
