Description

Technical Field

[0001] The utility model relates to the technical field of dump switches, in particular to a dump switch. Background Art

[0002] In the prior art, many electrical appliances, such as heaters, vibrating toys, sports equipment, electronic wind chimes, home security systems, etc., need to be provided with a dump switch to ensure safety in a dumped state, that is, when the electrical appliance dumps to a certain angle, the dump switch can shut down the electrical appliance to ensure safety. The dump switch in the prior art is of two types: mechanical and electronic. The electronic dump switch includes a transmitting tube, a receiving tube, a ball and a ball groove. Under normal circumstances, the ball is located between the transmitting tube and the receiving tube, blocking the receiving tube from receiving the photoelectric signal. In this state, the electrical appliance operates normally. When the electrical appliance dumps to a certain angle, the ball deviates from the original position, and the receiving tube receives the photoelectric signal sent by the transmitting tube, so that the receiving tube is turned on and generates a control signal. The control signal can be used to achieve the purpose of electrical appliance dumping control, thereby stopping the electrical appliance from running. When the electrical appliance returns to a certain angle, the ball returns to the normal position, blocking the receiving tube from receiving the photoelectric signal, and the receiving tube cannot be turned on, and the electrical appliance resumes normal operation.

[0003] In the prior art, the dump switches on the market are mainly mechanical contact switch structures, which are complex in structure, large in size, short in life, and not suitable for use in smaller equipment. The existing photoelectric dump switches also have some disadvantages, mainly manifested in that they are too large in size, complex in assembly, and have many processes, and are not suitable for automatic equipment production.

It solves some shortcomings of the existing photoelectric tipping switch, mainly manifested in the problems of too large size, complex assembly, numerous processes, and unsuitability for automatic equipment production.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tipping switch, comprising an outer seat, an outer cover is clamped on one side of the outer seat, an inner seat is arranged inside the outer seat, an inner cover is clamped on the top of the inner seat, a transmitting tube is installed at the bottom of the inner seat, a receiving tube is installed at the top of the inner cover, and a steel ball is movably connected between the inner seat and the inner cover.

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the utility model provides a dump switch, which has the following beneficial effects:

[0016] 1. Compared with the fully mechanical tipping switch, the tipping switch has a longer service life, better reliability and stability, and a continuous working life of more than 50,000 hours.

[0017] 2. The dump switch has a simple structure, small dimensions and low production cost.

[0018] 3. The internal and external structures of the tipping switch are mainly designed with a square profile. The joints between parts are designed to prevent fooling.
