Abstract
A water flow switch is disclosed. The characters of the switch can be concluded as follows, an inlet and outlet opening are arranged at both sides of the chamber body relatively, a holder is provided in the chamber, a magnetic chip is located on the upper pivot of the holder, the magnetic chip perpendicular to the flow direction of the inlet and outlet opening. On the chamber body a sensor hole is arranged on the cyclotron of the magnetic chip. The advantages: simple structure, smallness and skillfulness and high sensitivity.
Description
Technical field
The utility model relates to a kind of control switch, particularly a kind of water flow switch.
Background technology
Water flow switch is to utilize whether flowing of water to control a kind of switching device of break-make, have mechanical, as adopt bellows, when current during through pipeline, bellows is dilatation under the pressure effect of current, makes switch contacts or disconnection reach the purpose of control circuit break-make by mechanical structure; Electromagnetic type is arranged, and is a magnetic float is arranged in the pipe of vertical storing, and the pipe peripheral hardware has coil, when current make magnetic float enter coil, changes the inductance value of coil, via the break-make of circuit controling switch; Or being provided with tongue tube in pipe is outer, magnetic float is approaching or away from tongue tube under the effect of current, and makes the tongue tube on-off action.Existing above-mentioned various water flow switch ubiquity volumes are big, the shortcoming that sensitivity is low.
The utility model content
Technical problem to be solved in the utility model is, at the above-mentioned deficiency of prior art, and provide that a kind of volume is little, the water flow switch of high sensitivity, high reliability.
Water flow switch provided by the utility model is realized by following technical scheme.
Except that above-mentioned essential features, in specific implementation process, also can replenish following technology contents:
A kind of water flow switch, it is characterized in that: be provided with a cavity, both sides in cavity are provided with water inlet pipe and outlet pipe relatively, be provided with a support in the cavity, be pivoted with a magnetic piece on the support, the plane of this magnetic piece is vertical with the water (flow) direction of inlet tube and outlet tube, and cavity is provided with one and is provided with a gauge hole above this magnetic piece circles round.
Except that above-mentioned essential features, in specific implementation process, also can replenish following technology contents:
This magnetic piece is that a sheet magnet is housed in a sheet plastic box body, and the outside card front cover of magnet has the block of constant weight.
The diameter of this gauge hole is a bit larger tham the external diameter of tongue tube.
Also be provided with the spacing fin that revolves the position on the restriction magnetic piece in the both sides of this support.
Advantage of the present utility model is:
Simple in structure, small and exquisite, highly sensitive.
For architectural feature of the present utility model and effect thereof are had further understanding, enumerate specific embodiment now and be described with reference to the accompanying drawings as follows:
Description of drawings
Fig. 1 is a cutaway view of the present utility model.
Fig. 2 is the vertical view after the utility model is opened loam cake.
Embodiment
As shown in the figure, a kind of water flow switch provided by the utility model, it is: be provided with a cavity 1, this cavity 1 is provided with a loam cake 2, is provided with water inlet pipe 6 and outlet pipe 5 relatively in the both sides of cavity 1, is provided with a support 4 in the cavity 1, be pivoted with a magnetic piece 3 on the support 4, the plane of this magnetic piece 3 is vertical with the water (flow) direction of inlet tube and outlet tube 6,5, on the cavity 1, is provided with a gauge hole 7 above this magnetic piece 3 circles round.In the illustrated embodiment, this gauge hole 7 is to be arranged on the loam cake 2 of this cavity 1 top.The diameter of this gauge hole 7 is a bit larger tham the external diameter of tongue tube, supplies to place the tongue tube (not shown) in it.
This magnetic piece 3 is that a sheet magnet 31 is housed in a sheet plastic box body, and the outside card front cover of magnet 31 has the block 32 of constant weight, and the top of this slice plastic box body is pivoted with support 4 mutually with a hinge mechanism 33.
Also be provided with the spacing fin 8 that revolves the position on the restriction magnetic piece 3 in the both sides of this support 4.
When water when water inlet pipe flows to outlet pipe, current will promote magnetic piece 3 and rotate up around hinge mechanism 33, make magnet 31 near the tongue tube of being located in the cavity upper sensor hole 7, and tongue tube moves under the effect of magnet, adhesive or disconnection reach the purpose of control switch.By the position of adjusting tongue tube and the weight of adjusting the block 32 on the magnetic piece 3, the sensitivity of this water flow switch of scalable.
The above only is the utility model specific embodiment; everyly be familiar with this skill personage and make various modifications or change very easily in view of the above; therefore, all equivalence replacements that the utility model claim spirit is done that do not break away from all should be included in this patent protection range.
Claims (4)
