Description

Technical Field

[0001] The utility model belongs to a rebound automatic closing switch faucet, and particularly relates to a rebound automatic closing switch faucet. Background Art

[0002] A faucet is a common name for a water valve, which is used to control the size of the water flow switch and has the effect of saving water. The replacement speed of faucets is very fast. It has developed from the old cast iron process to the electroplated knob type, and then to the stainless steel single-temperature single-control faucet, stainless steel double-temperature double-control faucet, and kitchen semi-automatic faucet. For scientific research personnel, they also need to use faucets to receive water in the laboratory. Since there are many precision instruments in the laboratory, it is necessary to prevent accidental touch of the faucet and water splashing everywhere.

[0003] After retrieval, the Chinese utility model patent (authorization announcement number: CN212455578U) provides a faucet switch with an anti-misoperation structure, including a faucet housing and a protection plate. A hose is arranged in the middle of the bottom end of the faucet housing, and a gasket is adhesively connected to the outer side of the hose, and the outer side of the gasket is adhesively connected to the inner wall of the faucet housing. A delivery pipe is arranged inside the top end of the hose, and a sealing ring is adhesively connected to the outer side of the delivery pipe. A receiving plate welded to the inner wall of the faucet housing is arranged outside the top end of the delivery pipe, and a rubber plate is arranged above the receiving plate. An intermediate box is arranged inside the rubber plate, and a water outlet is opened inside the intermediate box. A connection plate is welded to the upper surface of the intermediate box, and a baffle is fixed to the left side surface of the connection plate. The protection plate is threadedly connected to the top end of the faucet housing, and a connecting rod is arranged in the middle of the protection plate. A movable block is welded to the upper surface of the connecting rod, and a strong spring is fixed inside the movable block. A first handle is arranged above the protection plate. A second handle penetrates through the first handle, and the connection mode between the second handle and the movable block is a clamping connection. A strong spring is fixed to the lower surface of the second handle.

[0004] The beneficial effects of the above prior art are as follows: The faucet switch with an anti-misoperation structure avoids water leakage, prevents the user from accidentally turning or pressing the second handle, thereby preventing accidental touch of the faucet switch and facilitating disassembly and assembly;

[0005] A hose, a delivery pipe and a sealing ring are arranged. The delivery pipe and the hose form a rotating structure through the sealing ring, and the sealing ring is used to prevent water from leaking out from the gap between the hose and the delivery pipe;

[0006] A first handle and a second handle are provided. When the second handle is pressed downwards, a strong spring is compressed, and the second handle is snapped into the interior of the movable block. Then, the first handle and the second handle are rotated to make the middle box rotate, adjusting the position of the water outlet, thereby turning on the faucet switch. When turning on the faucet switch, it is necessary to press and rotate the second handle to prevent the user from accidentally rotating or pressing the second handle.

[0007] However, the operation of the above-mentioned prior art is rather troublesome. It is necessary to first press down the second handle before the first handle can be rotated. Since a strong spring is provided on the lower surface of the second handle, the user needs to keep pressing down the second handle in order to further rotate the first handle. It is rather troublesome to turn on the faucet in two steps, so this shortcoming needs to be improved urgently. Utility Model Content

A connection head 53 is provided on the rotating member 5. A connection pipe 7 is sleeved and fitted on the outer periphery of the connection head 53. A socket cylinder 22 sleeved on the outside of the connection pipe 7 is provided on the knob 2. The knob 2 can reciprocally move between a first position and a second position along its axis direction. The rotating member 5 has a first working state and a second working state that rotate and switch along its axis direction;

[0033] When the rotating member 5 is in the first working state, the water inlet channel 11 is cut off from the water outlet channel 13;

[0034] When the rotating member 5 is in the second working state, the water inlet channel 11 is communicated with the water outlet channel 13 through the connection port 52;

[0035] When the knob 2 is in the first position, the socket cylinder is sleeved and fitted with the connecting pipe 7;

[0036] When the knob 2 is in the second position, the socket cylinder is disengaged from the connecting pipe 7.

[0037] The connecting pipe 7 has a first fitting cavity 71 therein. The cross-sectional shape of the first fitting cavity 71 is the same as the cross-sectional shape of the connecting head 53. In this application, the cross-sectional shapes of the first fitting cavity 71 and the connecting head 53 are in a toothed shape. In addition to the toothed shape, it can be any shape that can prevent relative rotation when the first fitting cavity 71 and the connecting head 53 are connected and fitted;

[0038] The socket cylinder 22 has a second fitting cavity therein. The cross-sectional shape of the second fitting cavity is the same as the cross-sectional shape of the connecting pipe 7. In this application, the cross-sectional shapes of the first fitting cavity 71 and the connecting head 53 are polygonal. In addition to the polygonal shape, it can be any shape that can prevent relative rotation when the first fitting cavity 71 and the connecting head 53 are connected and fitted.

[0039] A connecting plate 62 is provided on the connecting sleeve 6, and a clamping groove 210 for clamping and fitting with the connecting plate 62 is provided on the knob 2;

[0040] When the knob 2 is in the second position, the connecting plate 62 is clamped and fitted with the clamping groove 210;

[0041] When the knob 2 is in the first position, the connecting plate 62 is disengaged from the clamping groove 210.

[0042] An installation block 21 is provided on the knob 2, and the clamping groove 210 is arranged on the installation block 21.

[0043] A water inlet pipe 4 is inserted into the water inlet channel 11, and a water outlet pipe 3 is inserted into the water outlet channel 13, so as to facilitate the connection of external water pipes.

[0044] The outer part of the water outlet pipe 3 is arranged in a stepped shape. The outer circumference of the water outlet pipe 3 is used for sleeving a water pipe. The stepped arrangement of the water outlet pipe 3 can adapt to water pipes of different sizes.

[0045] A guide post 61 is provided on the connecting sleeve 6. The guide post 61 is used for positioning and installing the spring 8, so as to facilitate the positioning and installation of the spring 8.

[0046] The outer circumference of the knob 2 is in a "cross" shape, so as to facilitate the rotation of the knob 2 more conveniently.

[0047] Specific steps to turn on the faucet: Manually press the knob 2. At this time, the spring 8 is compressed to generate elastic potential energy, which causes the knob 2 and the mounting block 21 to move from the first position to the second position. As a result, the clamping groove 210 of the mounting block 21 is clamped and matched with the connecting plate 62, and the sleeve cylinder 22 is sleeved and matched with the connecting pipe 7. At this time, rotate the knob 2 to switch the knob 2 from the first working state to the second working state, causing the rotating member 5 to rotate, so that the connection port 52 on the rotating member 5 is communicated with the water inlet channel 11 and the water outlet channel 13, thus playing the role of opening the faucet.

[0048] Specific steps to turn off the faucet: Rotate the knob 2 in the reverse direction to switch the knob 2 from the second working state to the first working state, causing the rotating member 5 to reverse. At this time, the spring 8 releases the elastic potential energy, which causes the knob 2 to move away from the faucet housing 1. As a result, the knob 2 and the mounting block 21 move from the second position to the first position, so that the clamping groove 210 of the mounting block 21 is disengaged from the connecting plate 62, and the sleeve cylinder 22 is disengaged from the connecting pipe 7, thus realizing the function of closing the faucet.

[0049] In this application, simply pressing and rotating the knob 2 can achieve the opening and closing of the faucet. Therefore, the steps are fewer, and it is more convenient and easier to use. Moreover, when closing the faucet, the knob 2 will automatically reset, which is more convenient.
