Embodiment
Need to prove that in the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
As shown in Figure 1, the float liquid level switch of present embodiment comprises the float 10 that is along the longitudinal movement and the level switch 20 that cooperates with float 10, the second place that float 10 has the primary importance that makes level switch 20 conductings and level switch 20 is disconnected.
In the float liquid level switch of present embodiment, float and level switch are connected, and when the float gravitate was in the original position, namely during the second place, float disconnected level switch; When being subject to buoyancy of water, float vertically moves up, when float is moved upward to primary importance, and the level switch conducting that cooperates with float.Be subjected to buoyancy to vertically move to judge water level by float like this and control level switch and carry out monitoring water level, level switch compared to existing technology carries out monitoring water level by pressure transducer and controller etc., simple in structure, take up room little, and economize and used some soft and hardwares, saved production cost.
Preferably, float 10 has the connecting through hole 11 that extends transversely; Level switch 20 comprises Switch main body 21 and brace 23, Switch main body 21 has the conducting contact corresponding to brace 23 middle parts, the first end of brace 23 is connected on the Switch main body 21 pivotly, the second end is located in the connecting through hole 11, the middle part of brace 23 contacted with the conducting contact so that level switch 20 conductings when float 10 was positioned at primary importance, the middle part of brace 23 and conducting contact separation when float 10 is positioned at the second place so that level switch 20 disconnect.
Wherein, of particular note, brace 23 second ends are located in and comprise two kinds in the connecting through hole 11 and wear mode, and it is that brace 23 second ends pass completely through connecting through hole 11 that the first wears mode; It is that brace 23 second end sections penetrate in the connecting through hole 11 that the second wears mode; These two kinds wear mode and all can reach the connection effect that brace 23 is connected with connecting through hole, and brace 23 adopts in the present embodiment for the first wears mode, specifically referring to Fig. 1.
Preferably, the inwall of connecting through hole 11 is at the thickness of vertical spacing greater than brace 23.Because in the float liquid level switch of present embodiment, connecting through hole 11 is manhole, namely the diameter of connecting through hole 11 is greater than the thickness of brace 23.Arrange like this, in the process of float 10 risings or decline certain distance, will reach the effect that can not drive brace 23.The process that float 10 descends is specifically referring to Fig. 3 to Fig. 5, and more specifically effect is: make level switch 20 conductings when float 10 is subjected to buoyancy vertically to be moved upward to primary importance, general unwatering pump running during level switch 20 conducting, unnecessary water is discharged, float descended thereupon when water level descended, because the diameter of connecting through hole 11 is greater than the thickness of brace 23, when float drops to when brace 23 is contacted with the inwall the top of connecting through hole 11, brace 23 is just driven and makes middle part and the conducting contact separation of brace 23 by float 10, final level switch 20 disconnects.By the contact difference that cooperate of connecting through hole 11 with brace 23, avoided brace 23 and caused level switch 20 conductings and disconnect frequently problem because of float 10 small mobile variations, prolonged the life-span of level switch and unwatering pump.
Preferably, the concrete structure of the float liquid level switch of present embodiment is as follows: float 10 comprises the first cylindrical shell 13 and is connected to the second cylindrical shell 15 of the first cylindrical shell 13 1 ends, the diameter of the second cylindrical shell 15 is less than the diameter of the first cylindrical shell 13, the second cylindrical shell 15 has connecting portion away from an end of the first cylindrical shell, is provided with connecting through hole 11 on the connecting portion.Float 10 also comprises the stopper section 17 on the outer wall that is arranged on float 10, and stopper section 17 extends radially outward.
The utility model also provides the embodiment of external water pump, specifically referring to Fig. 2 to Fig. 5, external water pump comprises the float liquid level switch of water tank 31, dividing plate 33 and above-described embodiment, dividing plate 33 is horizontally set on the top of water tank 31, level switch 20 is installed on the dividing plate 33, and float 10 is arranged in the water tank 31.Dividing plate 33 has pilot hole, and the second cylindrical shell 15 is located in the pilot hole movably, and the diameter of pilot hole is less than the diameter of the first cylindrical shell 13.Dividing plate 33 has towards the limiting plate of straight down direction extension, is provided with the locating part with stopper section 17 clamping matching on the limiting plate.
Wherein, by the cooperation of the second cylindrical shell 15 and pilot hole, float 10 can be prolonged vertically upwards or move down, can not cause skew, avoided the problem that water level monitoring is inaccurate and brace 23 skids off from connecting through hole 11.Be affected by gravity vertically to be moved down at float 10 and just stop to move down when stopper section 17 and locating part offset, arrange like this and make that the second cylindrical shell 15 of float 10 can not skid off pilot hole when water tank wood has water.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
