Description
Technical field
The utility model relates to a kind of mercoid switch.
Background technology
Existing mercoid switch is of a great variety, and structure is also different, but mostly exists the defect that sensitivity is poor, be prone to wrong report.For improving sensitivity, some mercoid switches are not stinted and are adopted labyrinth, precious materials, so that cost is higher.
Separately, after existing mercoid switch action, the state that can only keep constantly path or open circuit, there is limitation in use on field.
The utility model content
Technical problem to be solved in the utility model is to provide that a kind of rate of false alarm is lower, sensitivity mercoid switch preferably.
For solving the problems of the technologies described above, the utility model provides a kind of mercoid switch, comprises housing, two metal electrodes lead-in wire, mercury, and housing is vertically arranged and is the sealing shape, the material of housing is electrical insulating material, and the top of two metal electrode lead-in wires and middle part be corresponding interval respectively;
Be provided with the dividing plate of horizontal arrangement in the inner chamber of housing, dividing plate is divided into upper chamber and lower chambers by the inner chamber of housing, has at least one liquid pass hole on dividing plate;
Be provided with inverted funnel in housing, funnel is communicated with and forms up and down by the liquid pipe of vertical layout, trumpet-shaped fluid cylinder, the upper side opening of fluid cylinder is little, open lower side is large, the upper end of dividing plate and liquid pipe is run through in upper chamber in the liquid-tight feud of liquid pipe, fluid cylinder in bottom chamber and and the locular wall of lower chambers between leave gap;
In top and the middle part tube chamber in the liquid pipe of two metal electrode lead-in wires, the top of each metal electrode lead-in wire is positioned at the top of liquid pipe, the lower end of each metal electrode lead-in wire passes after the middle part of liquid pipe or bottom, housing exposed outside housing successively, the middle part of each metal electrode lead-in wire and liquid pipe or bottom, housing liquid sealing respectively coordinate, two spaces, lower end that metal electrode goes between;
Mercury is in bottom chamber, and the liquid level peak of mercury is lower than the middle part of two metal electrode lead-in wires;
The material of dividing plate, funnel is electrical insulating material;

After the mercury Rapid Flow is crossed fluid cylinder, liquid pipe, corresponding interval is distinguished again at top and the middle part of two metal electrodes lead-in wire, two metal electrodes no longer electric connection that goes between, and this switch, again in off state, makes the external circuit outage.
Like this, this switch has been realized the complete course of work of open circuit-path-open circuit.
Now, housing is vertically arranged, mercury is downward from the periphery of liquid pipe, and the gap between liquid pass hole, fluid cylinder and the lower chambers locular wall of dividing plate is back to bottom chamber, and this switch is again in initial condition.
Known as mentioned above, mercury must advance in liquid-in pipe, just can external circuit be obtained electric two metal electrode lead-in wire moment electric connections, therefore this switch can be because of a little not rocking, just, by two metal electrode lead-in wire electric connections, its rate of false alarm is lower; Separately, funnel is communicated with and forms up and down by the liquid pipe of vertical layout, trumpet-shaped fluid cylinder, and the upper side opening of fluid cylinder is little, open lower side is large, thus this switch during to any direction inclination certain angle, all can be by two metal electrodes lead-in wire moment electric connections, its sensitivity is better.
Separately, relatively simple for structure due to this switch, also make its cost lower.
As optimization of the present utility model, described housing is engaged and is sealed to form up and down by the first shell, the second shell.
Like this, this switch is made easily, is overhauled conveniently.
As further optimization of the present utility model, described dividing plate is located at the inner chamber upside of the second shell, and the outer circumference of dividing plate is to uniform four liquid pass holes;
The shape of cross section of liquid pipe is circular, and the central area of dividing plate is run through in the liquid-tight feud of liquid pipe;
The radially both sides that the top of two metal electrode lead-in wires and middle part lay respectively at the liquid pipe, the several times ground, top of each metal electrode lead-in wire is wound around, passes from outside to inside the top of liquid pipe, the winding arrangement formed for some bar shaped circles between the top that makes each metal electrode go between and the top of liquid pipe;
The middle part bending of each metal electrode lead-in wire;
The lower end of each metal electrode lead-in wire passes behind the bottom, the second shell of liquid pipe exposed outside housing successively, the lower end of each metal electrode lead-in wire is lower than dividing plate, each metal electrode lead-in wire coordinates with bottom, the second shell difference liquid sealing of liquid pipe, and the lower end of two metal electrode lead-in wires lays respectively at the radially both sides of the second shell.
The setting of four liquid pass holes, can guarantee that mercury successfully is back to bottom chamber through described liquid pass hole; Described winding arrangement, make location, the top tube chamber upper volume better, the liquid pipe of metal electrode lead-in wire diminish, and can further guarantee that mercury is after in fluid cylinder advances liquid-in pipe, by two metal electrodes lead-in wire moment electric connections; Metal electrode lead-in wire lower end lays respectively at the radially both sides of the second shell lower than the lower end of dividing plate and two metal electrode lead-in wires, make being connected more for convenience of this switch and external circuit.
