DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Embodiment 1

[0021] See also Figure 1-3 A ball valve with anti-pollution capability includes a valve seat 1, which is composed of a rotating valve disc, a rotating rod, a rotating valve and a shell. The diameter of the valve seat 1 is larger than the diameter of the connecting pipe 2. The setting of the rotating valve on the valve seat 1 can effectively achieve a switching effect by controlling the valve disc to rotate through the rotating rod. The two sides of the valve seat 1 are fixedly connected to the connecting pipe 2, and the interior of the connecting pipe 2 is fixedly connected to a connecting base 31. One side of the connecting base 31 is fixedly connected to an elastic telescopic rod 41, and the connecting pipe 2 can be effectively connected to the water pipe. Fixed sealing devices 3 are set on both sides of the connecting pipe 2:

[0022] The fixed sealing device 3 includes a connecting base 31, a gas bag 32 is fixedly connected to the bottom of the connecting base 31, a gas pipe 33 is fixedly connected to the bottom of the gas bag 32, a pressure chamber 34 is fixedly connected to the other side of the gas pipe 33, the pressure chamber 34 is fixedly connected to the outside of the connecting pipe 2 through a fixing seat 35, an exhaust valve is arranged on one side of the pressure chamber 34, the material of the gas bag 32 is a one-way air intake material, and the exhaust valve 34 can effectively drive the gas pressure rod 36 to move after gas is injected into the inside. A fixing seat 35 is fixedly connected to one side of the pressure chamber 34, a gas pressure rod 36 is slidably connected to one side of the pressure chamber 34, a fixing clamp 37 is fixedly connected to the other side of the gas pressure rod 36, and a sealing sponge 38 is fixedly connected to the other side of the fixing clamp 37. The sealing sponge 38 is made of a material with high waterproofness and good shape adaptability. The initial shape of the sealing sponge 38 is the same as that of the fixing clamp 37. The sealing sponge 38 can effectively fix and seal the joint between the connecting pipe 2 and the water pipe. The present application can effectively fix the connection between the external water pipe and the connecting pipe 2 by fixing the anti-leakage device 3, and prevent water leakage at the connection between the water pipe and the connecting pipe 2, and can also prevent external dust from entering the connection between the water pipe and the connecting pipe 2. It is highly practical and convenient when it is necessary to separate the entire device from the water pipe.

[0023] When in use, the water pipe is first docked with the connecting pipe 2. After one side of the water pipe enters the docking groove on one side of the docking seat 42, the water pipe is pushed by manpower, and the water pipe will drive the docking seat 42 to move toward the inside of the connecting pipe 2. After moving a certain distance, the docking seat 42 will squeeze the airbag 32. After being squeezed by the docking seat 42, the airbag 32 will transport the internal gas to the air pressure cabin 34 through the air pipe 33. After the air is injected into the air pressure cabin 34, it will drive the air pressure rod 36 to move, and the air pressure rod 36 will drive the fixing clamp 37 to tighten the connection between the water pipe and the connecting pipe 2. At the same time, the sealing sponge 38 will effectively seal the connection between the water pipe and the connecting pipe 2 to prevent external dust from entering and prevent water leakage after the entire device has been used for a long time. After the water pipe is connected to the entire device, it can be used. When it is necessary to separate the water pipe from the entire device, the gas in the air pressure cabin 34 is discharged through the exhaust valve. After the gas in the air pressure cabin 34 is discharged, the air pressure rod 36 and the fixing clamp 37 will return to their original positions. At this time, the water pipe can be separated from the entire device, and the air bag 32 will slowly absorb external air and return to its original state after being not squeezed.

[0024] Embodiment 2

[0025] See also Figure 1-4 On the basis of the first embodiment, anti-pollution devices 4 are further provided on both sides of the connecting pipe 2:

[0026] The anti-pollution device 4 includes an elastic telescopic rod 41, one side of the elastic telescopic rod 41 is fixedly connected to a docking seat 42, one side of the docking seat 42 is provided with a water pipe docking groove, and the inner side of the docking seat 42 is provided with a clamping groove, and the docking groove on one side of the docking groove 42 can be docked with the water pipe, which is highly practical. The inner side of the docking seat 42 is clamped with a filter element 43. The present application uses the anti-pollution device 4 to effectively filter the water inside the water pipe through the filter element 43 after the water pipe is fixedly docked with the entire device, further enhancing the practicality of the entire device. The filter element 43 can be replaced, and the operation is simple and convenient.

[0027] When in use, on the basis of the first embodiment, the water pipe is first connected to the entire device. After the connection is completed, the entire device can be used. When in use, the filter element 43 will filter the water in the water pipe to achieve an anti-pollution effect. After a period of use, the filter element 43 needs to be replaced, and the gas in the air pressure cabin 34 is discharged through the exhaust valve. The air pressure rod 36 will return to its original position after there is no gas drive, and the fixing clamp 37 will release the fixation of the connection between the water pipe and the connecting pipe 2. After the fixation is released, the elastic telescopic rod 41 will return to its original position by its own elastic force after being subjected to external force. At the same time, the docking seat 42 will also return to its original position. After the docking seat 42 returns to its original position, the water pipe and the docking seat 42 can be separated. After removing the water pipe, the filter element 43 is replaced, the filter element 43 is removed, and a new filter element 43 is replaced and clamped in the clamping groove, and then the water pipe and the entire device are docked and installed and put back into use, which further enhances the practicality of the entire device and extends the service life of the entire device.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
