Description
Technical field
The present invention relates to a kind of accessory of heater, especially a kind of escape protection device of heater.
Background technology
Quartz tube heater, simple in structure, the thermal efficiency is high, health environment-friendly, in productions such as fast-heating type drinking machine, water heaters
It is widely used in product.But the ferrule of quartz ampoule is bad, and it is easily broken after being hit, it can lead
Quartzy tube leakage is caused, and then can make Electric radiant Heating Film and electrode in quartzy pipe outer wall that leak electricity short-circuit occur, can also make the water band of leakage
Electricity, there is security risks.
To solve the above problems, people specially devise some escape protection devices, such as patent No. for heater
201320296743.9《A kind of calandria escape protection device》, the water for collecting percolating water is arranged below in calandria in it
Slot is placed with the inflating medium of water-swellable in sink, the jacking block that can touch microswitch is equipped with above inflating medium；Microswitch
On calandria, it can cut off control circuit with reflation media expansion formula because jacking block touches.
But triggered since the microswitch only relies only on deformation caused by the expansion of inflating medium, expander is again
It is arranged outside heater, after moisture natural evaporation in expander, jacking block loses support, once more by the power supply of calandria
Circuit in an ON state, is powered at this time, is particularly easy to cause the danger got an electric shock with Electric radiant Heating Film short circuit.
Invention content
The technical problems to be solved by the invention：A kind of escape protection device of heater is provided, when leak occurs, it
It will be triggered and can remain circuitry cuts state, and be conducive to overhaul.
Technical solution is used by the present invention solves the above problems：A kind of escape protection device of heater, including it is micro-
Dynamic switch, slide bar, expander and pedestal, microswitch are connected on the heater circuit of heater, the control-rod of microswitch with
The end thereof contacts of slide bar, it is characterised in that：The pedestal includes Storage water tank, expansion chamber and spring cavity, Storage water tank and expansion chamber it
Between have a through-hole, expander is mounted in expansion chamber, and slide bar is arranged between expansion chamber and spring cavity, and is limited to be only capable of horizontal shifting
Dynamic, one end of slide bar and expander contact, the other end and the spring being fixed in spring cavity contact；It is provided with card on the slide bar
Slot；When there is water in Storage water tank, it is inflated body by through-hole and absorbs, expander expansion, compressed spring, slide bar is moved to the left, micro-
The control-rod of dynamic switch is fallen within card slot, and microswitch disconnects, and cuts off heater circuit；When the water evaporation of Storage water tank is dry, expansion
When body is restored to compact state, spring pushes slide bar to reset to the right, but the control-rod of microswitch is stuck in card slot, Bu Nengfu
Position, thus microswitch will persistently keep heater circuit dissengaged positions.
The expander is non-woven fabrics compression body, bentonite or macromolecule sponge compression body.
The expander is rectangular or cylindrical.
The microswitch is hilted broadsword or multipole switch.
Compared with the prior art, the advantages of the present invention are as follows：Once leak occurs, it will trigger rapidly and can protect always
Heater circuit disconnection, and " memory " malfunction are held, is conducive to repair.
Escape protection device uses lateral Slide bar structure, control-rod and the slide bar contact of microswitch, the end of slide bar
Portion compresses the control-rod of microswitch upwards, and microswitch is made to connect, heater circuit power supply；When there is water in Storage water tank, pass through
Through-hole is inflated body and absorbs, and expander expansion, compressed spring, slide bar is moved to the left, the control-rod of microswitch fall into card slot it
Interior, microswitch disconnects, and cuts off heater circuit.When the water evaporation of Storage water tank is dry, when expander is restored to compact state, spring pushes away
Moving slide-bar resets to the right, but the control-rod of microswitch is stuck in card slot, cannot reset, thus microswitch will persistently be kept
Heater circuit dissengaged positions avoids leaking electricity.
When the microswitch is multipole switch, the zero curve and firewire of circuit will be cut off simultaneously, thoroughly eliminate the hidden of electric leakage
Suffer from.
Description of the drawings
The structural schematic diagram of Fig. 1, the present invention（When non-leak）.
The structural schematic diagram of Fig. 2, the present invention（When leak）.
The structural schematic diagram of Fig. 3, the present invention（When state is kept）.
Specific implementation mode
A kind of escape protection device of heater, including microswitch 1, slide bar 4, expander 5 and pedestal 2, microswitch 1
It is connected to the heater circuit of heater（It is omitted in figure）On, the end thereof contacts of the control-rod 11 and slide bar 4 of microswitch.
The pedestal 2 includes Storage water tank 21, expansion chamber 22 and spring cavity 23, there is through-hole 24 between Storage water tank and expansion chamber,
Expander 5 is mounted in expansion chamber 11, and one end of slide bar 4 and expander 5 contact, the other end and the spring being fixed in spring cavity
3 contacts；Card slot 41 is provided on the slide bar 4.
The expander 5 is non-woven fabrics compression body, bentonite or macromolecule sponge compression body, and shape is rectangular or cylinder
Shape.When expander 5 is cylindrical, bottom surface and slide bar are in contact.
The microswitch is hilted broadsword or multipole switch.Recommend to use multipole switch, while cutting off the zero curve of heater circuit
And firewire.When other circuits of heater being avoided to connect, zero curve band high pressure is caused, causes to get an electric shock.
The Storage water tank 21 is set to the lower section of heating tube, or by conduit by each easy leak in fast-heating type drinking machine
Place drain into Storage water tank.
As shown in Figure 1, in normal work, control-rod and the slide bar contact of microswitch, the end of slide bar compresses upwards
The control-rod of microswitch, makes microswitch connect, heater circuit power supply.
As shown in Fig. 2, when leak occurs, start water storage in Storage water tank, water 6 enters by through-hole 24 in expansion chamber 22, quilt
Expander 5 absorbs.Expander 5 expands, and compressed spring 3, slide bar 4 is moved to the left, and the control-rod 11 of microswitch falls into card
Within slot 41, microswitch disconnects, and cuts off heater circuit.
As shown in Figure 1, after microswitch triggering, control-rod 11 will fall into card slot 41.Even if water 6 is done by natural evaporation, swollen
Swollen body 5 restores, and push rod moves right under the thrust of spring 3, will block control-rod 11, and heater circuit will be kept to cut off shape
State when avoiding being again started up, causes electric leakage.
This is designed with conducive to the safety of protection user, prevents accidental shock, and heater can be made to keep malfunction,
Facilitate work-up failure and repair.
