Abstract
The switch controlled by the gravity relates to a switch with linear operation. A sliding block (5) in the utility model is set in a housing (11) for sliding; a force measure spring (3) is set in the slide housing (11) which is at the top of the sliding block (5), the slide housing (11) has an aperture (12) facing a moving rod (9), a jacking spring (6) arranged in a slot (13) of the sliding block (5) connects with a sliding ball (7), the sliding ball (7) has a sliding contact with the moving rod (9) arranged with a fulcrum (8). The gravity controlled switch is accurate in measures; stable and sensitive in action has a wide applicability, and can be widely used in electric kettles, electric food warmers and other electric heaters.
Description
Technical field
The utility model belongs to the electric switch field, has to relate to a kind of switch with linear operating.
Background technology
In order to realize control for various situations, need various electric switches at electric field, wherein, be exactly a kind of by the switch of GRAVITY CONTROL.It can realize automatic detection and control for different predetermined weights or position.For example, electric kettle just needs this switch.In order to prevent the danger of kettle dry combustion method, behind the employing Weight detecting switch, if kettle run out or few water, Weight detecting switch just can detect, and circuit disconnects then.Weight detecting switch of the prior art has adopted flash switch, but the defective of flash switch is a complex structure, be difficult for installing, and the making precision height of requirement, and switch motion is insensitive.
The utility model content
The purpose of this utility model is to provide a kind of check weighing accurate, and reliable in action, sensitivity are installed simple GRAVITY CONTROL switch.
The utility model is achieved through the following technical solutions:
The switch of the GRAVITY CONTROL that the utility model relates to, comprise shell, be positioned at the fixed contact of shell, moving contact, weight sensing spring, slide block is arranged in the sliding chamber, and weight sensing spring is arranged in the sliding chamber on slide block top, and moving relatively bar place is provided with sliding chamber opening in sliding chamber, top spring and slip spheroid connect as one, the top spring is arranged in the slotted hole that slide block offers, slip spheroid and moving bar sliding contact, and moving bar is provided with a fulcrum.
Adopt the switch of the GRAVITY CONTROL of technical solutions of the utility model realization, check weighing is accurate, and reliable in action, sensitivity are installed simply, have adaptability widely.
Description of drawings
Accompanying drawing 1 is a cutaway view of the present utility model.
Among the figure: 1. fixed contact; 2. moving contact; 3. weight sensing spring; 4. upper cover plate; 5. slide block; 6. top spring; 7. slip spheroid; 8. fulcrum; 9. moving bar; 10. shell; 11. sliding chamber; 12. sliding chamber opening; 13. slotted hole.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
The switch of the GRAVITY CONTROL that technical solutions of the utility model relate to comprises the shell 10 that is used for insulating protection, and upper cover plate 4.A sliding chamber 11 is set in shell 10, in the sliding chamber 11 slide block 5 is set, be provided with a weight sensing spring 3 between slide block 5 tops and sliding chamber 11, slide block 5 can slidably reciprocate in sliding chamber 11.After connecting as one with slip spheroid 7, top spring 6 is arranged in the slotted hole 13 that slide block 5 offers.In shell 10, also be provided with the fixed contact 1 and the moving contact 2 of switch, in order to external connection electric wiring.Moving contact 2 is positioned on the moving bar 9, and moving bar 9 is provided with a fulcrum 8.
Below describe the course of work of switch again in detail.Such as this switch is used for electric kettle, this switch can be as a leg of electric kettle, and fixed contact 1 and moving contact 2 are serially connected with among the electric wiring.If the water in the electric kettle does not reach the position of regulation, so, electric heating tube will damage because of dry combustion method, after adopting this switch, by the weight of the water in the weight sensing spring 3 measurement electric kettles, also be the position of water, if water does not reach the position of electric kettle regulation, weight sensing spring 3 displacements are not enough, top spring 6 is also not enough with 7 displacements of slip spheroid, and so, slip spheroid 7 just can not promote moving bar 9 and rotate around fulcrum 8, fixed contact 1 and moving contact 2 can be not closed, and switch is in off-state.
Otherwise, if water has reached the position of electric kettle regulation, weight sensing spring 3 displacements are enough, slide block 5 moves up, drive top spring 6 and move on slip spheroid 7, slip spheroid 7 is positioned at the top of fulcrum 8, and slip spheroid 7 applies power for moving bar 9, moving bar 9 rotates fixed contact 1 and moving contact 2 closures around fulcrum 8.
The switch of the GRAVITY CONTROL that technical solutions of the utility model relate to can be widely used in electrical heated appliances such as electric kettle, electric heating pot.
Claims (1)
1. switch by GRAVITY CONTROL, comprise shell (10), be positioned at the fixed contact (1) of shell (10), moving contact (2), weight sensing spring (3), it is characterized in that slide block (5) is arranged in the sliding chamber (11), weight sensing spring (3) is arranged in the sliding chamber (11) on slide block (5) top, moving relatively bar (9) locates to be provided with sliding chamber opening (12) in sliding chamber (11), top spring (6) connects as one with slip spheroid (7), top spring (6) is arranged in the slotted hole (13) that slide block (5) offers, slip spheroid (7) and moving bar (9) sliding contact, and moving bar (9) is provided with a fulcrum (8).
