Abstract
The invention relates to a high-power water level switch for a main engine water tank of a water heating blanket. The high-power water level switch for the main engine water tank of the water heating blanket consists of a main engine water tank, a fixing rod, a floating body, a rubber diaphragm, a connecting rod and a travel switch, and is characterized in that the floating body is mounted inside the main engine water tank; the fixing rod vertically penetrates through the floating body from the middle; a switch arm of the travel switch is connected with the floating body through the connecting rod; the floating body is horizontally mounted inside the water tank through the fixing rod, and is connected with the switch arm of the travel switch through the connecting rod, so that when the floating body rises and falls, the switch arm of the travel switch is driven through the connecting rod and the travel switch switches on or off a power cord, and thus a purpose of directly controlling a load is achieved. The high-power water level switch is reasonable and simple in integral structure, so that the production cost is reduced; the travel switch is independent of the floating body and is not soaked in water, so that the service life of the travel switch is prolonged and the high-power 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 water tank.
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, expands with heat and contract with cold, the generation of incrustation scale, and the time has been grown and will stuckly damage, and dry spring can only by faint signal code, be not by big current, control heating tube also will increase auxiliary relay, because this increasing use cost.
Summary of the invention:
The object of the present invention is to provide a kind of structure simple, switching mechanism does not steep in water and water lev el control is accurate, the high-power water level switch of long service life.
The present invention is achieved in that
The high-power water level switch of a kind of water warming blanket main frame water tank, it includes: main frame water tank 1, fixed lever 2, buoyancy aid 3, rubber diaphragm 4, connecting rod 5, travel switch 6 forms, it is characterized in that: described buoyancy aid 3 device is in main frame water tank 1, buoyancy aid 3 bar 2 that is fixed runs through from intermediate vertical, the switch arm of travel switch 6 is connected with buoyancy aid 3 by a connecting rod 5, described buoyancy aid 3 is connected with the switch arm of travel switch 6 by connecting rod 5 in water tank 1 by fixed lever 2 horizontal device, described travel switch 6 is that any switch is a kind of, described travel switch 6 is fixed on water tank 1 outer wall, an aperture is made a call at described rubber diaphragm 4 center, connecting rod 5 passes from centre bore and seals, rubber diaphragm 4 to be pressed together on water tank 1 and to seal, described solid bar 2 is at water tank 1 internal fixtion, described buoyancy aid 3 is fixed together with fixed lever 2, be fixed on water tank wall with total fixed support 7.
Structure of the present invention is simple, travel switch, under the effect of buoyancy aid power, drives travel switch work by linkage, thus improves the stability of whole host work and the reliability of switch, travel switch and buoyancy aid independent agency, switch not to steep in water thus extends useful life.
Accompanying drawing explanation
Fig. 1, enforcement of the present invention one side mounting structure schematic diagram
Fig. 2, enforcement of the present invention one end face mounting structure schematic diagram
Fig. 3, enforcement of the present invention three structural representation
In figure: 1-water tank, 2-fixed lever, 3-buoyancy aid, 4-rubber diaphragm, 5-connecting rod, 6-travel switch, the total fixed support of 7-.
Embodiment
Execution mode and operation principle is further described below in conjunction with accompanying drawing 1,2,3:
Embodiment one:
See accompanying drawing 1, 2: it includes: 1-water tank, 2-fixed lever, 3-buoyancy aid, 4-rubber diaphragm, 5-connecting rod, 6-travel switch forms, it is characterized in that: described buoyancy aid 3 device is in main frame water tank 1, buoyancy aid 3 bar 2 that is fixed runs through from intermediate vertical, the switch arm of travel switch 6 is connected with buoyancy aid 3 by a connecting rod 5, when lack of water in water dim blanket main frame water tank 1 is prescribed a time limit for 3 times to buoyancy aid, drivening rod 5 mechanism action while that buoyancy aid 3 falling, the switch arm of travel switch 6 is not under pressure, self resilience of travel switch 6 disconnects, whole water tank does not heat with pump water thus plays protection, when toward water tank 1 water filling, at this moment buoyancy aid 3 starts to float drivening rod mechanism action simultaneously, the switch arm of travel switch 6 is under pressure, travel switch 6 closing of contact, whole water tank main frame starts heat pump water, electrothermal tube and water pump can directly be connected in the middle of civil power with travel switch 6, do not need to connect auxiliary relay, can direct deenergization when lack of water, signal of water shortage lamp point, resume work until add water.
Embodiment two:
Be exactly different in structure see accompanying drawing 3: Fig. 3 and Fig. 1,2 difference, described buoyancy aid 3 passes through connecting rod 5 by fixed lever 2 horizontal device and is connected with the switch arm of travel switch 6 water tank 1 in, and operation principle is the same with above-mentioned.
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.
