[0034] Reference Figure 2 , Figure 3 and Figure 5 The tube body 1 is connected to the filter basket 4 through a mounting mechanism 5. The mounting mechanism 5 includes an upper cover 51. A groove matching the shape of the tube body 1 is provided at the bottom end of the upper cover 51, and both sides of the bottom end of the upper cover 51 close to the tube body 1 are set with rounded corners. Through the setting of the rounded corners, the upper cover 51 can be more easily connected to the tube body 1. An air pressure chamber 52 is provided on the inner wall of the upper cover 51. A push plate 53 is connected to the inner wall piston of the air pressure chamber 52. The outer wall of the push plate 53 fits the inner wall of the air pressure chamber 52. The top of the push plate 53 is rotatably connected to a screw rod 54. The outer wall of the screw rod 54 passes through and is threadedly connected to the inner wall of the upper cover 51. A hand-held ball 55 is fixedly connected to the top of the screw rod 54. Through the setting of the hand-held ball 55, it is easier for the staff to rotate the screw rod 54 and lift the upper cover 51.

[0035] Reference Figure 2 , Figure 5 and Figure 6 A connecting rod 56 is fixedly connected to the bottom end of the upper cover 51. The number of the connecting rods 56 is set to four, and the connecting rods 56 are respectively arranged on the left and right sides of the tube body 1 on the front and rear sides of the connecting pipe 2. The position setting of the connecting rod 56 ensures that the connecting rod 56 has less contact with the water flow. An air chamber 57 is opened at the top of the connecting rod 56, and the air chamber 57 is connected to the air pressure chamber 52. An outer ring 59 is passed through and fixedly connected to the outer wall of the connecting rod 56. The shape of the outer ring 59 is an inclined elliptical ring. The bottom end of the air chamber 57 is flush with the bottom end of the outer ring 59. The interior of the outer ring 59 is set to be hollow. The interior of the outer ring 59 is connected to the interior of the air chamber 57. An air bag 58 is fixedly connected to the outer wall of the outer ring 59. The shape of the air bag 58 matches the shape of the outer ring 59. The material of the air bag 58 is set to rubber. The interior of the air bag 58 is connected to the interior of the outer ring 59. The outer wall of the outer ring 59 is fixedly connected to the top of the outer wall of the filter basket 4.

[0036] Reference Figure 1 , Figure 4 and Figure 5The upper cover 51 is connected to the outer wall of the tube body 1 through a fixing component 6. The fixing component 6 includes a sliding groove 61. The number of the sliding grooves 61 is set to be several, and the several sliding grooves 61 are in a ring array. The sliding groove 61 is opened on the inner wall of the upper cover 51. The inner wall of the sliding groove 61 is slidably connected with a block 62. The shape of the block 62 is a shape formed by connecting a hemisphere and a cylinder. One end of the block 62 away from the middle of the tube body 1 is elastically connected to the inner wall of the sliding groove 61 through a spring 63. One end of the spring 63 is fixedly connected to one end of the block 62 away from the middle of the tube body 1, and the other end of the spring 63 is fixedly connected to the inner wall of the sliding groove 61. When the spring 63 is in the original length state, the block 62 has and only has a hemispherical part outside the sliding groove 61. The upper cover 51 A rotating groove 66 is provided on the inner wall below the sliding groove 61, and a turntable 67 is rotatably connected to the inner wall of the rotating groove 66. A sliding groove 64 is provided on the top of the turntable 67. The shape of the sliding groove 64 is arc-shaped, and the distances between different positions of the sliding groove 64 and the center point of the upper cover 51 are inconsistent. A control rod 65 is provided inside the sliding groove 64. When the spring 63 is at its original length and the control rod 65 is at the position farthest from the center point of the upper cover 51, the distance between the control rod 65 and the block 62 is exactly equal to the radius of the hemispherical area of ​​the block 62. The outer wall of the control rod 65 is slidably connected to the inner wall of the upper cover 51. The outer wall of the turntable 67 is provided with a protrusion that penetrates the inner wall of the upper cover 51, and the material of the protrusion is set to be a magnet. The material of the upper cover 51 is set to iron with an anti-rust coating on the outside.

[0037] Working principle: During use, when the staff completes the cleaning of the filter basket 4 and needs to reinstall it, the staff first places the filter basket 4 into the tube body 1 with the bottom end at the left end and the top end at the right end. Since the outer wall of the outer ring 59 is smaller than the inner wall of the tube body 1, the outer ring 59 can be placed into the tube body 1 even if the filter basket 4 is tilted at a certain angle during the installation process.

[0038] After the outer ring 59 is inserted, the staff continues to move the device downward until the upper cover 51 contacts the top of the tube body 1. Since the bottom end of the upper cover 51 is provided with a groove matching the top of the tube body 1, and both sides of the groove are rounded, the top of the tube body 1 can easily enter the groove at the bottom end of the upper cover 51 through the rounded corners. After entering the groove, when the top of the upper cover 51 enters the non-rounded area on the upper side of the groove, the tube body 1 is coaxially arranged with the upper cover 51 at this time. Therefore, at this time, the filter basket 4 remains coaxially arranged with the tube body 1 under the control of the connecting rod 56.

[0039] During the installation of the upper cover 51, after the outer wall of the upper cover 51 contacts the rounded corner of the block 62, the block 62 can be pushed by the curved surface of the block 62, so that the block 62 enters the interior of the sliding groove 61. When the top of the groove at the bottom end of the upper cover 51 fits with the top of the upper cover 51, the staff slightly rotates the upper cover 51 left and right. When the block 62 and the groove 68 are rotated to the same plane, the block 62 moves in the direction of entering the groove 68 under the elastic force of the spring 63, so that the staff can feel the resistance during the rotation. Therefore, when the staff feels the resistance, it can be determined that the position of the filter basket 4 is completely correct at this time.

[0040] When the positioning is completed, the staff rotates the turntable 67 through the protrusion of the turntable 67 on the outside of the upper cover 51 while manually fixing the upper cover 51, so that the position of the groove on the turntable 67 and the sliding path of the control rod 65 in the same plane changes, so that the control rod 65 moves to a position close to the middle of the tube body 1 under the control of the groove. Since in the initial state of the control rod 65, the distance between the control rod 65 and the block 62 is equal to the distance between the block 62 and the sliding groove 61, the block 62 is not hindered by the control rod 65 when it is squeezed into the sliding groove 61. When the control rod 65 moves, the control rod 65 first moves to a position in contact with the block 62. After contact, the control rod 65 continues to move, driving the block 62 to move, and the control rod 65 pushes the block 62 deeper into the groove 68. Therefore, at this time, the cylindrical area of ​​the block 62 enters the groove 68. Therefore, even if the upper cover 51 is subjected to an external left-right rotation force, it cannot rotate relative to the tube body 1.

[0041] After the position of the tube body 1 and the upper cover 51 is fixed, the staff rotates the screw 54 so that the screw 54 rotates and is controlled to move downward through the threaded groove on the inner wall of the upper cover 51, thereby pushing the push plate 53, and the push plate 53 pushes the gas below it, so that the gas below the push plate 53 enters the gas chamber 57 through the air pressure chamber 52, so that the gas inside the gas chamber 57 is pushed into the inner part of the outer ring 59 and finally enters the air bag 58, so that the air bag 58 expands, so that the outside of the outer ring 59 fits against the inner wall of the tube body 1, so as to fix the position of the outer ring 59 and fill the gap between the outside of the outer ring 59 and the tube body 1 at the same time, thereby ensuring that the water must be filtered by the filter basket 4 during the flow process, and will not pass through the gap between the tube body 1 and the outer ring 59, thereby ensuring the filtering effect.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
