Abstract
The utility model discloses a fixed-stroke water pump for water level control, comprising a pump body, a switch disposed in the pump body for controlling the starting and closing of the water pump, a shifting rod stretching out of the pump body from one side of the switch and a floating rod disposed outside the pump body and with a hollow interior. The floating rod moves up and down under the buoyancy function of water and drives the shifting rod to move up and down, thereby triggering the switch; because the fluctuation to water level of the floating rod is more sensitive than that of the floating ball of a water level controller, the sensitivity of the fixed-stroke water pump for water level control of the utility model is higher, and a precise control to the water pump switch can be realized in a set water level range; additionally, because the switch is disposed in the pump body and the part of the shifting rod stretching out of the pump body is protected by an insulated sheath, electric wires cannot be exposed outside, the occupied space of the fixed-stroke water pump for water level control of the utility model is greatly reduced, and the safe performance is greatly improved.
Description
Technical field
The utility model relates to a kind of water pump, is specifically related to a kind ofly can decide formula water level control of pump according to what water level height automatically controlled water pump was opened or closed
Background technique
The water level control of pump of prior art is normally by coming the unlatching of control of pump or closing from the outwardly directed floating ball type water level controller of the pump housing.Because floating ball type water level controller links to each other with the pump housing by electric wire, electric wire is all soaked in water usually, in case electric wire breakage, damage water pump easily even cause shock hazard, very dangerous, ball float floats simultaneously needs enough float areas, and so just the usage space to water pump has proposed certain requirement.In addition, the sensitivity of floating ball type water level controller is not high yet, and for the occasion that must open or close according to the accurate control of pump of water level, the water level control of pump of this ball float external just is difficult to realize
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and providing a kind of can decide formula water level control of pump according to what the accurate control of pump of SEA LEVEL VARIATION was opened or closed, and its sensitivity is higher, takes up room little and moves safer.
For solving above technical problem, the utility model is taked following technological scheme:
A kind ofly decide formula water level control of pump, comprise the pump housing and be used for control of pump and start and the switch of closing, wherein, switch is arranged in the pump housing and has switch contact, this water pump also comprises the control unit that opens and closes by the switch contact control switch, this control unit comprises the driving lever that stretches out and vertically is arranged on the fly rod of the pump housing outside and boring outside a side direction pump housing of switch, driving lever can be arranged on the sidewall of the pump housing with swinging up and down, its end that is positioned at the pump housing is used for the touch switch contact, it is positioned at the top that the outer part of the pump housing is used to connect fly rod, fly rod moves up and down under the buoyancy of water effect and drives driving lever and moves up or down, and the periphery that is positioned at the outer part of the pump housing of driving lever is provided with insulation sleeve.
Further, describedly decide formula water level control of pump and comprise also and be arranged on the outer cover that the fly rod periphery is used to protect fly rod that this outer cover is provided with the hole that can supply water and pass through.
Because the enforcement of above technological scheme, the utility model compared with prior art has following advantage:
The utility model is decided formula water level control of pump and is moved up and down by the driving lever that the fly rod drive fly rod top that vertically is arranged on the pump housing outside and boring is connected, and then the startup of touch switch contact control of pump with close, because fly rod is more responsive to the ball float of the fluctuation ratio floating ball type water level controller of water level, it is higher to make the utility model decide the sensitivity of formula water level control of pump, can realize the accurate control of pump switch; In addition, because switch is arranged in the pump housing, and driving lever stretches out the outer part of the pump housing and protects with insulation sleeve, and it is exposed outside therefore not have electric wire, and this makes the utility model decide formula water level control of pump to take up room forr a short time in use that Security is higher.
Description of drawings
Fig. 1 decides the structural representation of formula water level control of pump for the utility model;

Wherein: 1, the pump housing; 2, switch; 20, switch contact; 3, driving lever; 4, fly rod; 5, insulation sleeve; 6, outer cover.
Embodiment
The utility model is described in more detail below in conjunction with specific embodiment, but be not limited to these embodiments.
Embodiment
As illustrated in fig. 1 and 2, decide formula water level control of pump according to present embodiment, comprise the pump housing 1 and be arranged on and be used for the switch 2 that control of pump starts and closes in the pump housing 1, switch 2 has switch contact 20, this water pump also comprises the control unit that opens and closes by switch contact 20 control switchs 2, this control unit comprises driving lever 3 that stretches out and the fly rod 4 that vertically is arranged on the pump housing 1 outside and boring outside a side direction pump housing 1 of switch 2, driving lever 3 can be arranged on the sidewall of the pump housing 1 with swinging up and down, its end that is positioned at the pump housing 1 is used for touch switch contact 20, it is positioned at the top that the pump housing 1 outer part is used to connect fly rod 4, fly rod 4 moves up and down under the buoyancy of water effect and drives driving lever 3 and moves up or down, and the periphery that is positioned at the part outside the pump housing 1 of driving lever 3 is provided with insulation sleeve 5.
Be further protection fly rod 4, also be provided with outer cover 6 in the periphery of fly rod 4, outer cover 6 is provided with the hole to be passed through with water supply.
Base plane with the pump housing 1 is a horizontal plane, present embodiment decide formula water level control of pump can be in the scope of water level 20mm～180mm accurately control of pump unlatching or close, and the water pump of present embodiment is as safe as a house when using, it is little to take up room.
More than the utility model has been done detailed description; its purpose is to allow the personage that is familiar with this art can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to spirit of the present utility model change or modify, and all should be encompassed in the protection domain of the present utility model
