DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-Figure 4 The suction tube body 1 is provided with a semicircular plate 2 at the bottom, and a plurality of liquid-passing grooves 7 are opened on the arc-shaped outer wall of the semicircular plate 2. An elastic cover 6 is bonded to the inner wall of one side of the semicircular plate 2. A plurality of air outlet holes 11 are opened on the arc-shaped outer wall of the elastic cover 6. An adsorption component for driving the elastic cover 6 to restore the original state is arranged in the elastic cover 6. An iron head 9 is fixed to one end of the shaft rod 3 by bolts, and the iron head 9 is in contact with the elastic cover 6 to push the shaft rod 3. The shaft rod 3 drives the iron head 9 to move, so that the iron head 9 squeezes the elastic cover 6, and the accumulated liquid in the elastic cover 6 is squeezed out through the air outlet holes 11, thereby blowing away the large foreign matter blocking the liquid-passing groove 7, so that the large foreign matter is blocked outside the semicircular plate 2 and cannot enter the suction tube. At the same time, the large foreign matter can be blown away to avoid the large foreign matter blocking the liquid-passing groove 7, thereby improving the fluidity of the suction tube.

[0024] In the utility model, the adsorption component is a magnetic block 13, which is bonded to the inner wall of one side of the elastic cover 6, and the magnetic block 13 can adsorb the iron head 9. When the shaft rod 3 is pulled back, the shaft rod 3 drives the iron head 9 adsorbed by the magnetic block 13 to move, so that the deformed elastic cover 6 can be restored to its original state, and then it can be reused, further improving the fluidity of the suction tube. Cutters 5 are bonded in multiple liquid grooves 7. When debris passes through the liquid grooves 7, the debris will be cut into two halves by the cutter 5 when it contacts the cutter 5, thereby reducing the size of the debris. The suction tube body 1 includes an inner tube body 15 and an outer tube body 14. There is a pressure relief cavity between the inner tube body 15 and the outer tube body 14, and the top of the pressure relief cavity is directly connected to the external air. A plurality of pressure relief holes 16 are provided on one side of the outer tube body 14, and the pressure relief holes 16 are connected to the pressure relief cavity. The external air The air passes through the pressure relief cavity formed between the inner tube body 15 and the outer tube body 14 and enters the accumulated fluid through the pressure relief hole 16. The suction tube can be used inside the body, which increases the use range of the suction tube. The circumferential inner wall of the suction tube body 1 is rotatably connected to a turntable 4. A plurality of guide grooves 8 are provided on the upper surface of the turntable 4. The accumulated fluid and debris continue to be attracted and will pass through the guide grooves 8 on the turntable 4 into the suction tube body 1. The guide grooves 8 opened at the oblique mouth will be driven by the flow of the accumulated fluid to rotate the turntable 4. Two scrapers 10 are welded to the circumferential inner wall of the semicircular plate 2, and the scrapers 10 are symmetrically distributed. The scrapers 10 are in contact with the turntable 4 to prevent debris from blocking the guide grooves 8 and thus being unable to be attracted. A spacer 12 is provided at the bottom of the magnetic block 13, and the spacer 12 is fixed to the elastic cover 6 to prevent the magnetic block 13 from directly contacting the accumulated fluid and protecting human organs from bacterial invasion.

[0025] Working principle: When in use, the suction tube body 1 is extended to the accumulated liquid to suck the accumulated liquid. During the suction process, the accumulated liquid and foreign matter will enter the semicircular plate 2 through the liquid groove 7. When the debris passes through the liquid groove 7, the small pieces of debris will contact the cutter 5 and will be cut into two halves by the cutter 5, so that the size of the small pieces of foreign matter is smaller and less likely to block the suction tube. The accumulated liquid and foreign matter continue to be attracted and will pass through the guide groove 8 on the turntable 4 into the suction tube body 1. The guide groove 8 opened at the oblique mouth will be driven by the flow of the accumulated liquid to rotate the turntable 4, and the scraper 10 will contact the turntable 4 to prevent debris from blocking the guide groove 8, so that it cannot be attracted. When a large piece of foreign matter blocks the liquid tank 7, the suction of the suction tube is stopped, and the shaft 3 is pushed. The shaft 3 drives the iron head 9 to move, so that the iron head 9 squeezes the elastic cover 6, and the accumulated liquid in the elastic cover 6 is squeezed out through the air outlet 11, thereby blowing away the large piece of foreign matter blocking the liquid tank 7, so that the liquid tank 7 can flow. When the shaft 3 is pulled back, the shaft 3 drives the iron head 9 adsorbed by the magnetic block 13 to move, so that the compressed elastic cover 6 returns to its original state, thereby solving the problem of inefficiency of using soft steel wire or other things to push out foreign matter when foreign matter is blocked in the suction tube.

[0026] Finally, it should be noted that: for those skilled in the art, they can still modify the technical solutions recorded in the above embodiments, or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this utility model shall be included in the protection scope of this utility model.
