Description

Technical Field

[0001] The utility model relates to the field of electric heaters, in particular to an anti-dumping switch. Background Art

[0002] An electric heater converts electrical energy into heat. With the reform of my country's heating system and the improvement of people's living standards, new heating methods are constantly emerging, and electric heating is becoming an increasingly indispensable option. Currently, domestic electric heating methods are mainly divided into heating cable floor radiant heating, electric film heating, and electric heaters, with electric heaters showing the fastest growth. Electric heaters generate heat through ceramic heating elements. They use a fan to force air through the heating element for forced convection as the primary heat exchange method. This allows for flexible temperature adjustment, gentle air flow, rapid temperature rise, and automatic constant temperature control. The elements are generally waterproof, making them ideal portable household heaters. Among them, vertical fan heaters are lightweight, easy to carry, and suitable for a variety of environments, suitable for use in most areas of the house. Existing vertical electric heaters have a small footprint, which means a small support surface, posing a certain risk of tipping over. This is especially true in homes with large pets or children, where the heater can easily tip over, causing property damage. Anti-tip switches play a crucial role in electric heaters.

[0014] The effect achieved by the above components is: the elastic member is arranged between the first contact and the second contact, so that when the electric heater falls over, the pressure of the pressing component changes, and the elastic member uses its own restoring force to separate the first contact and the second contact, so as to achieve the effect of current non-conduction.

[0015] Preferably, a fixing column is extended from the upper end of the upper shell; the pressing assembly is arranged in the fixing column; the pressing assembly includes an outer shell and a pressing column arranged in the outer shell.

[0016] The effects achieved by the above components are: by providing the outer shell and the pressing column, and arranging the pressing component in the fixed column, the stability of the structure is improved.

[0017] Preferably, a first limiting portion is arranged on the fixing column; a second limiting portion is arranged on the bottom of the outer shell; and the first limiting portion and the second limiting portion can be connected in abutting manner.

[0033] like Figures 1 to 3 As shown, the utility model provides

[0034] An anti-dump switch includes a housing assembly 1 consisting of an upper housing 11 and a lower housing 12, wherein a pressing assembly 3 is arranged inside the housing assembly 1; a metal sheet assembly 2 is arranged below the pressing assembly 3; and an elastic member 4 is arranged between the metal sheet assemblies 2. During normal use, the pressing assembly 3 moves downward to connect the metal sheet assemblies 2 so that the circuit is conductive; when tipping occurs, the elastic member 4 rebounds to disconnect the metal sheet assemblies 2 so that the circuit is not conductive. By setting up a pressing component 3 and a metal sheet component 2, when the pressing component 3 is pressed downward, the metal sheet components 2 can be connected to each other so that the circuit is turned on; the end of the pressing component 3 away from the metal sheet component 2 is in contact with the ground. When in normal use, the pressing component 3 will be pressed by the weight of the electric heater itself to connect the metal sheet components 2 to turn on the circuit; when tipping over occurs, the pressing component 3 will not be able to completely contact the ground. At this time, the metal sheet components 2 will be separated by the rebound force of the elastic part 4, so that the circuit is not turned on; such a design improves safety and has a simple structure.

[0035] The metal sheet assembly 2 includes a first metal sheet 21 and a second metal sheet 22 fixed to the lower housing 12. The first metal sheet 21 includes a first connecting portion 23 and a second connecting portion 24. The second metal sheet 22 includes a third connecting portion 25 and a fourth connecting portion 26. The first metal sheet 21 and the second metal sheet 22 allow for electrical conduction through the first metal sheet 21 and the second metal sheet 22.

[0036] One end of the first connecting portion 23 extends outward from the lower housing 12; the second connecting portion 24 is disposed on the lower housing 12; and a first contact 27 is disposed on the second connecting portion 24. One end of the first connecting portion 23 extends out of the lower housing 12 for connection to the internal circuit of the electric heater; the first contact 27 is provided for electrical communication with the second metal sheet 22.

[0037] One end of the third connecting portion 25 extends outward from the lower housing 12; the fourth connecting portion 26 is disposed on the lower housing 12; and a second contact 28 is disposed on the fourth connecting portion 26. One end of the third connecting portion 25 extends out of the lower housing 12 for connection to the internal circuit of the electric heater; the second contact 28 is disposed for electrical communication with the first metal sheet 21.

[0038] The elastic member 4 is disposed between the first contact 27 and the second contact 28. The elastic member 4 is disposed between the first contact 27 and the second contact 28 so that when the electric heater falls over, the pressure of the pressing assembly 3 changes, and the elastic member 4 uses its own restoring force to separate the first contact 27 and the second contact 28, thereby achieving the effect of current conduction.

[0039] A fixing post 13 extends from the upper end of the upper housing 11; the pressing assembly 3 is disposed within the fixing post 13. The pressing assembly 3 includes an outer shell 31 and a pressing post 32 disposed within the outer shell 31. The outer shell 31 and the pressing post 32, with the pressing assembly 3 disposed within the fixing post 13, enhance the stability of the structure.

[0040] A first stopper 14 is disposed on the fixing post 13, and a second stopper 33 is disposed at the bottom of the outer shell 31. The first stopper 14 and the second stopper 33 are interlockingly connected. The provision of the first stopper 14 and the second stopper 33 prevents the pressing assembly 3 from falling out of the fixing post 13 when returning to its original position, thereby improving the stability of the structure.

[0041] The pressing post 32 contacts the fourth connection portion 26 . The fourth connection portion 26 is pressed by the pressing post 32 , so that the second contact 28 can be connected to the first contact 27 .

[0042] The upper shell 11 and the lower shell 12 are fixedly connected by a snap-fit structure and / or a threaded connection. The above-mentioned connection method improves the stability and firmness of the structure. Specific embodiments

[0043] During normal operation, the weight of the electric heater causes the pressing assembly 3 to press against the fourth connection portion 26, thereby connecting the first contact 27 and the second contact 28 provided on the metal sheet assembly 2 and completing the circuit. If the electric heater falls over, the pressing assembly 3 will no longer be able to fully contact the ground, and the resilience of the elastic member 4 will cause the first contact 27 and the second contact 28 to separate, disconnecting the circuit.
