Description

Safety structure of hot water switch handle

This creation is mainly a water dispenser with cold water and hot water faucets. This creation is a safety switch used to control a hot water faucet. It refers to a safety switch handle structure that can lock the valve of the hot water faucet.

Conventional water dispensers are equipped with two separate faucets for hot and cold. Both hot and cold faucets are equipped with a switch handle. However, in order to prevent children from accidentally touching or improper operation of the hot water faucet, hot water will flow out and burns. For users, some companies have developed safety switches to maintain safe operation. For example, patent number: M313226 faucet safety switch, including: a faucet seat, a valve device and a safety switch, the faucet seat is provided with a hole for use In combination with the valve device, the valve device is provided with a fixed part and a rotary switch, the rotary opening relationship is used to control the boiling or closing of the faucet, and the safety opening relationship is combined with the valve device; the safety switch includes: A swivel part is fixed on the rotary switch, so that when the safety switch is turned, the rotary switch will be driven; and, a handle, the handle is assembled on the swivel part; and, a clip, the clip is arranged on Between the swivel part and the handle, the bottom end of the clip abuts against the valve device. When you want to open the faucet, you need to pull up the handle first to make the bottom end of the clip leave the valve device before the valve device can rotate. It is the safety structure of the switch handle.

However, the switch handle has too many structural elements. When it is combined with the rotating body, it needs The tool can be assembled smoothly to avoid idling when combining the switch handle components.

For this reason, the purpose of this creation is to simplify the components of the switch handle, solve the difficulty of combination and improve it.

This creation is to provide a safety structure for the switch of the hot water faucet of the drinking fountain, including: a faucet body, a valve device and a control device. One end of the faucet body is a cold water outlet, and the opposite end is a hot water outlet. This creation is set at the hot water outlet, the valve device is set in the hot water outlet, and the control device is correspondingly set on the valve device to drive the valve device. It is characterized in that the control device includes: a rotating body part , A lock element, a handle and a push rod, a spring, the rotating body is correspondingly set on the valve device, and the valve device can be pivotally driven; and the handle has an accommodating space, and the push rod is sleeved A spring is placed in the accommodating space of the handle; and, one end of the push rod is placed in the rotating body, and the placed end is assembled with the lock element, and the lock element and the push rod are perpendicular to each other; And, the valve device is provided with a notch, the shape of the notch corresponds to the anastomosis of the lock element; and when the user presses the handle down, the push rod is simultaneously pressed down, whereby the lock element leaves the notch of the valve device , The swivel part can be rotated by the handle drive shaft, and then the swivel part can drive the valve device to open the hot water channel; and, the user returns the handle-driven swivel part to the original position and releases the handle to push the lever As the spring assists in its resetting, the lock element returns to the corresponding notch, whereby the rotating body part cannot be rotated because the lock element is locked to the valve device, so as to lock the valve device from being opened.

Please refer to the first picture to the second picture for this creation, including: a faucet body 1, a valve device 2 and a control device A. One end of the faucet body 1 is a cold water outlet, and the opposite end is a hot water outlet. Water channel 11, this creation is set at the hot water outlet 11, the valve device 2 is set in the hot water outlet 11, the control device A is corresponding to the valve device 2 to drive the valve device 2, the valve device 2 is provided with an assembling part 21, an end of the assembling part 21 is provided with a ring 22, the circumferential end of the ring 22 is provided with a notch 221, and the central axis of the assembling part 21 is extended with a shaft part 23, the ring part There is an annular channel 222 between 22 and the shaft portion 23; and, the control device A includes: a rotating body 3, a push rod 4, a spring 5, a lock element 6, and a handle 7. The rotating body 3 has a shaft The sleeve portion 33 is correspondingly assembled on the shaft portion 23 of the valve device 2 so that the rotating body 3 can drive the valve device 2 axially; and, one end of the rotating body 3 on the circumferential side extends A sleeve portion 31 is provided, the sleeve portion 31 has a passage 32, a ring recess 311 is provided on the outer edge of the sleeve portion 31, and a restriction ring 312 is sleeved on the ring recess 311; and the push rod 4 has a first end 4a And an extended second end 4b, the first end 4a is provided with a threaded portion 42, the second end 4b is provided with an inner screw hole 41; and the spring 5 is sleeved on the first end 4a of the push rod 4 And, the second end 4b of the push rod 4 is inserted into the push rod 4 by the sleeve portion 31 of the rotating body 3 and then the lock element 6 is screwed into the inner screw hole 41, the lock element 6 and The pushing rods 4 are perpendicular to each other; and, the handle 7 has an accommodating space, and an internal thread portion is provided along the accommodating space, the pushing rod 4 is sleeved with the spring 5 and then placed in the accommodating space of the handle 7 , The push rod 4 is screwed to the internal threaded portion by the threaded portion 42 to be combined with the handle 7; and, a cover portion 8 is assembled on the upper part 71 of the handle 7; and, the The lock element 6 corresponds to the position of the gap 221 of the ring portion 22 of the valve device 2.
