[0001] The utility model relates to the field of water boiler, especially to a child safety faucet. BACKGROUND

[0002] At present, the water outlet of the water boiler is generally press type water outlet valve or directly uses electromagnetic valve to control water outlet. The water boiler using electromagnetic valve to control water outlet has certain operation ability, so it directly uses electronic child lock to prevent children from touching by mistake. When hot water is needed, two buttons on the panel are pressed at the same time to release the child lock. The general water boiler has simple structure and generally uses mechanical valve structure to control water outlet, which is easy to cause children to touch by mistake. There is no electronic component to realize automatic control, so the electronic child lock cannot be used to prevent children from touching by mistake. The water boiler is generally used in public places such as stations, so it is easy to cause children to touch by mistake, resulting in safety accidents such as scalding. SUMMARY

[0003] In order to overcome the defects of the prior art, the utility model provides a child safety faucet.

[0004] The utility model discloses the following technical scheme is realized: a child safety faucet, including the water outlet pipe body of installation on the water boiler, be equipped with the valve for closing or opening the water outlet pipe body on the lateral wall of water outlet pipe body, the top of valve stretches out the valve rod for driving the valve action, be equipped with the driving handle on the valve rod;

[0005] The driving handle includes an outer driving part and an inner locking part, the outer driving part is rotatably connected to the valve rod, and the outer driving part is folded to drive the valve rod to stretch out or retract in the water outlet pipe body.

[0006] The outer driving part is provided with a containing cavity, the valve rod is inserted into the containing cavity from the bottom of the containing cavity, and the inner locking part is arranged in the containing cavity and slides along the side wall of the containing cavity. When the inner locking part slides to the bottom of the containing cavity, the end of the inner locking part is clamped between the valve rod and the outer driving part.

[0007] The outer driving part includes a handle, an installation hole is formed in the center of the handle to form a containing cavity, and the inner locking part is arranged in the installation hole and slides along the inner wall of the installation hole.

[0008] The inner locking part includes a driving twist, a transmission rod, a locking rod and a compression spring, a sliding groove is formed in the side wall of the installation hole, the locking rod is arranged in the sliding groove and slides along the length direction of the sliding groove, the driving twist is arranged at the end of the transmission rod, and the compression spring is arranged between the driving twist and the inner wall of the installation hole and abuts.

[0009] One end of the locking rod is engaged with the valve stem, and the other end of the locking rod is connected to the transmission rod. The movement of the transmission rod causes the locking rod to move away from or closer to the valve stem.

[0010] A locking slot is provided at one end of the locking rod, and the locking slot is inserted into the end of the valve rod when the locking rod approaches the valve rod.

[0011] The inner wall of the mounting hole has a through hole near one end of the valve stem for the locking rod to be inserted. The locking rod passes through the through hole and is inserted into the end of the valve stem.

[0012] Compared to existing technologies, in the initial state, the spring of this invention is in a relaxed state but still has preload. The preload of the spring is used to press the drive torque downwards, which in turn pushes the locking rod towards the valve stem. The locking lever's locking position directly engages with the end of the valve stem, preventing the external drive unit from rotating and thus preventing the valve stem from being lifted; therefore, the faucet cannot dispense water in this state. To dispense water, the drive torque must first be pressed upwards, compressing the spring. This pulls the locking lever, disengaging the locking position from the end of the valve stem. Maintaining this state, flipping the external drive unit allows the valve stem to be lifted, thus dispensing water from the faucet. In other words, to dispense water from this faucet, two actions are required, and one of these actions must be maintained throughout the entire process. This makes opening the faucet difficult for children, thus achieving a child safety lock function and reducing the occurrence of scalding accidents in public places. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0018] Referring to Figures 1-2 A child safety faucet, comprising a water outlet pipe body 1 installed on a water boiler, a valve 2 is arranged on the side wall of the water outlet pipe body 1 for closing or opening the water outlet pipe body 1, the top of the valve 2 extends a valve rod 3 for driving the valve 2 to act, and a driving handle 4 is arranged on the valve rod 3. The valve rod 3 and the valve 2 on the water outlet pipe body are both the valve 2 commonly used in the prior art on the water boiler, and thus the structure thereof will not be described herein. In the present application, only the handle 41 for driving the valve rod 3 is improved, which is referred to as the driving handle 4 hereinafter.

[0019] The driving handle 4 in the embodiment comprises an outer driving part and an inner locking part. The outer driving part is rotationally connected to the valve rod 3, and the outer driving part is folded to drive the valve rod 3 to extend or retract in the water outlet pipe body 1. The outer driving part is provided with a receiving cavity 42, and the valve rod 3 is inserted into the receiving cavity 42 from the bottom of the receiving cavity 42. The inner locking part is arranged in the receiving cavity 42 and slides along the side wall of the receiving cavity 42. When the inner locking part slides to the bottom of the receiving cavity 42, the end of the inner locking part is engaged between the valve rod 3 and the outer driving part. The inner locking part is installed in the receiving cavity 42 of the outer driving part and can slide inside the outer driving part. When the inner locking part slides to the bottom of the outer driving part, the inner locking part locks the valve rod 3. Since the inner locking part is installed on the outer driving part, the entire outer driving part cannot be turned over when the inner locking part is engaged on the valve rod 3. In this way, the situation of accidental touch can be prevented. When water is needed, the inner locking part is directly pushed to slide away from the valve rod 3, and the outer driving part can be turned over again to lift the valve rod 3 to open the faucet to discharge water, thereby improving the safety and reducing the possibility of accidental touch of children when the faucet is used in public places.

[0020] In the embodiment, the outer driving part comprises a handle 41, and a mounting hole is formed in the center of the handle 41 to form the receiving cavity 42. The inner locking part is arranged in the mounting hole and slides along the inner wall of the mounting hole. The inner locking part comprises a driving knob 43, a transmission rod 44, a locking rod 45, and a compression spring 46. A sliding groove is formed in the side wall of the mounting hole, the locking rod 45 is arranged in the sliding groove and slides along the length direction of the sliding groove, the driving knob 43 is arranged at the end of the transmission rod 44, and the compression spring 46 is arranged between the driving knob 43 and the inner wall of the mounting hole and abuts against the inner wall. One end of the locking rod 45 is engaged on the valve rod 3, and the other end of the locking rod 45 is connected with the transmission rod 44. The transmission rod 44 moves to drive the locking rod 45 to move away from or close to the valve rod 3. When the locking rod 45 is close to the valve rod 3, the end of the locking rod 45 is inserted into the valve rod 3. When the handle 41 has a tendency to be turned over, the valve rod 3 and the locking rod 45 form a hard contact, and thus the entire inner locking part is actually installed on the handle 41. When the handle 41 is turned over, the locking rod 45 cooperates with the valve rod 3 to form a locking position for the handle 41, thereby reducing the possibility of accidental touch of children when the faucet is used in public places and improving the safety.

[0021] One end of the locking rod 45 in the embodiment can be provided with a locking clamping portion 47, and the locking clamping portion 47 is inserted into the end portion of the valve rod 3 when the locking rod 45 approaches the valve rod 3. A through hole is formed in the inner wall of the mounting hole near the end of the valve rod 3, the locking rod 45 is inserted through the through hole and is connected to the end portion of the valve rod 3. In the initial state, the compression spring 46 is in a relaxed state but still has a pre-tightening force. At this time, the pre-tightening force of the compression spring 46 drives the torsion 43 to be pressed downward. Then, the locking rod 45 is pushed towards the valve rod 3, so that the locking clamping portion 47 of the locking rod 45 is directly clamped on the end portion of the valve rod 3, at this time, the outer driving portion cannot be rotated and cannot lift the valve rod 3, that is, the faucet cannot be watered in this state. When water is needed, the torsion 43 needs to be pressed upward first, so that the compression spring 46 is in a compressed state, at this time, the locking rod 45 is in a pulled state, and then the locking clamping portion 47 is separated from the end portion of the valve rod 3, and then the outer driving portion is turned over to pull the valve rod 3, so that the faucet of the present application can be watered.

[0022] Compared with the prior art, in order to make the faucet of the present application water, two actions need to be completed and one action needs to be maintained during the whole process of opening the faucet, so that it is difficult for children to open the faucet, that is, the function of child safety lock is realized, and the occurrence of scalding accidents in public places is reduced.

[0023] The above-mentioned embodiments are only preferred embodiments of the utility model, and cannot be used to limit the scope of protection of the utility model, and any non-substantial changes and replacements made by those skilled in the art on the basis of the utility model all belong to the scope of protection required by the utility model.
