Description

Leakage circuit breaker structure

The invention relates to a circuit breaker technology, in particular to a leakage circuit breaker structure.

According to a survey by the World Health Organization, human diseases are closely related to drinking water in daily life. However, with the increase in population and industrial development, water sources are gradually becoming scarce in many areas, and drinking water in some cities has suffered from water sources. Pollution, the safety of drinking water in residents' lives has been valued; and because the old water pipes or water towers have no habit of cleaning, the water pipes and water towers can also produce dirt over many years, especially for E. coli, which cannot be ignored, Therefore, the related companies have developed various water purifier equipments for the public to purchase and install.

In general, water purifier equipment is generally provided with a leakage circuit breaker, so that when water leakage or overflow occurs in the water purifier equipment, it can be immediately detected to avoid water damage to the floor, decoration and items, or water resources. A lot of waste happened.

Existing leakage circuit breakers are mostly through the mutual cooperation of the valve body and the piston valve stem, and the valve stem can be moved linearly relative to the passage inside the valve body to achieve the blocking effect. However, due to the linear movement of the valve stem, it is easy to cause the failure of the action due to the excessive water pressure and the water cannot be cut off.

In view of this, the present inventors have devoted themselves to the above-mentioned prior art, researched intensively and cooperated with the application of science to try to solve the above-mentioned problems, which has become the goal of the inventors' improvement.

It is an object of the present invention to provide a water leakage circuit breaker structure, which utilizes the mutual cooperation of a valve stem assembly and a turnbuckle element to achieve stable operation, sensitive response and long service life.

In order to achieve the above object, the present invention provides a leakage circuit breaker structure, which includes a base, a valve stem assembly, a turnbuckle element and an expansion body. The base has a valve body and an inlet connecting the valve body. The valve body has a receiving groove; the valve stem assembly includes a valve stem, a spiral arm and a torsion spring; one end of the valve rod penetrates the receiving groove and the other end is connected with the screw; The arm is connected, and the valve rod penetrating the accommodation slot is provided with a channel, which is operable to communicate or block the water inlet connector and the water outlet connector. One end of the torsion spring is fixed to the rotary arm and A pre-twisting action is formed on the swivel arm; the swivel element is pivotally connected to the base, the swivel element has a buckle corresponding to the swivel arm and a driven arm extending from the buckle; The expansion body is installed corresponding to the driven arm to actuate the rotary buckle element to generate a rotational swing.

The invention also has the following effects. The valve stem is used to achieve communication or blocking in a rotating manner, which not only has no problem of displacement, but also has a good effect of shutting off water. With the setting of the hard component, the stability of the driven arm of the expansion body can be improved. In this case, the rotary arm is used to drive the valve stem to rotate and change the valve together in a rotating manner, and a larger torque force can be obtained under the condition that the force arm is long; the other is 90 ° in the water inlet and outlet directions. Under the action of torsion, it can still easily achieve the effect of blocking and shutting off water when the water inlet pressure is high.

In addition, a pivot joint base 15 extends upward from another corner of the bottom plate 11, and a hollow cylinder 16 extends from one side of the pivot joint base 15.

Further, a blocking member 17 extends on a side of the valve body 12 adjacent to the water outlet joint 14, and a clamping groove 123 is provided near the port of the receiving pipe 122. The hollow cylinder 16 is provided with a notch 161 on a side facing the pivot joint 15.

The valve stem assembly 20 includes a valve stem 21, a swivel arm 22, and a torsion spring 23. One end of the valve stem 21 penetrates into the accommodation groove 121 from the aforementioned receiving pipe 122, and the other end of the valve stem 21 is connected with the swing arm 22 Connected, the valve rod 21 is provided with a water inlet hole 211 and a water outlet hole 212 in a portion penetrating the accommodation groove 121. The water inlet hole 211 and the water outlet hole 212 communicate with each other and form an L-shaped channel A (ie, 90 ° included angle), this channel A It is operative to form communication or blocking with the water inlet joint 13 and the water outlet joint 14. In a normal state, the water inlet hole 211 is configured corresponding to the aforementioned water inlet joint 13 and the water outlet hole 212 is configured corresponding to the aforementioned water outlet joint 14 so as to form a communicating path.
