Abstract
Description
Technical Field

[0025] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered.
[0026] A nasal irrigator for nasopharyngeal carcinoma patients includes a water tank 1 and a cover 2. A locking assembly 3 is provided between the water tank 1 and the cover 2. The locking assembly 3 includes a hinge 4 hinged to the side of the cover 2. A retaining edge that cooperates with the hinge 4 is provided on the side of the water tank 1. A pressurizing assembly 5, a water pipe assembly 6, and a nozzle assembly 7 are provided on the cover 2. A first pressure chamber 8 is formed between the water tank 1 and the cover 2. An elastic pressure plate 9 is slidably provided on the bottom surface of the cover 2. A spring 10 is provided between the elastic pressure plate 9 and the bottom surface of the cover 2. A second pressure chamber 11 is formed between the elastic pressure plate 9 and the cover 2. A pressure relief hole 12 communicating with the second pressure chamber 11 is provided on the cover 2. The pressurizing assembly 5 is used for... The pressure in the first pressure chamber 8 is increased. When the pressure in the first pressure chamber 8 rises, the elastic pressure plate 9 compresses the spring 10 and forces the air in the second pressure chamber 11 out through the pressure relief hole 12. When the spring 10 is compressed to its limit position, the pressure in the first pressure chamber 8 can no longer increase. At this time, it is the maximum pressure stored in the first pressure chamber. The bottom of the cover 2 is also provided with a guide frame 13. The guide frame 13 has a guide groove 14. The side end of the elastic pressure plate 9 is slidably connected to the guide frame 13. The guide frame 13 is fixed to the cover 2 by screws. The bottom of the guide frame 13 is provided with a limit frame 15. The limit frame 15 is used to limit the stroke of the elastic pressure plate 9.
[0027] One end of the water pipe assembly 6 is connected to the nozzle assembly 7, and the other end is located at the bottom of the water tank 1. The nozzle assembly 7 is also equipped with a hydraulic control component 16, which is used to control the liquid pressure sprayed from the nozzle assembly 7. When the pressure in the first pressure chamber 8 increases, the water in the first pressure chamber 8 will enter the nozzle assembly 7 from the water pipe assembly 6. By setting the hydraulic control component 16, the liquid pressure sprayed from the nozzle assembly 7 is relatively easy to control, thereby preventing excessive hydraulic pressure from causing nasal discomfort.
[0028] The nozzle assembly 7 includes a nozzle 17 and a handle 18. A first flow channel 19 is provided in the handle 18, and a button hole 20 is provided on the side end of the handle 18. The button hole 20 communicates with the first flow channel 19. The hydraulic control component 16 includes a button post 21 and a spring 22. A water passage hole 23 is provided in the middle of the button post 21. The spring 22 is located between the bottom surface of the button post 21 and the button hole 20. The spring 22 drives the button post 21 to protrude from the button hole 20 and causes the button post 21 to block the first flow channel 19. When the button post 21 is installed, the water passage moves toward the first flow channel 19 and gradually makes the water passage hole 23 communicate with the first flow channel 19. The liquid pressure sprayed by the nozzle 17 is controlled according to the area of the water passage hole 23 protruding from the first flow channel 19.
[0029] The button post 21 has a plunger hole 24 on its side, and a spring plunger 25 is installed in the plunger hole 24. The spring plunger 25 is existing technology and will not be described in detail here. The button hole 20 has several first annular grooves 26 on its side. When the spring plunger 25 touches the first annular groove 26, it will generate elastic feedback, thereby informing the user of the position of the button post 21, so that the user can remember the more suitable water spray pressure. The button post 21 also has several second annular grooves 27, and a rubber sealing ring 28 is installed in the second annular groove 27, thereby increasing the sealing between the button post 21 and the button hole 20.
[0030] The pressurizing assembly 5 includes a tube 29, a piston plate 30, a spring 45, and a piston rod 31. The spring 45 is disposed between the piston plate 30 and the tube 29. The tube 29 is fixedly mounted on the cover 2 and has a piston chamber 32. The piston plate 30 is slidably disposed within the piston chamber 32. A first one-way valve 33 is disposed on the piston plate 30. A second one-way valve 34 is disposed on the top of the tube 29. The piston rod 31 is fixed to the piston plate 30 and extends out of the tube 29. An air hole 46 is also provided at the bottom of the tube 29. The first one-way valve 33 controls that gas can only enter the first pressure chamber 8 through the air hole 46, preventing the second one-way valve from entering the first pressure chamber 8. The gas in the first pressure chamber 8 flows back, and the second one-way valve 34 allows the gas at the upper end of the piston plate 30 in the tube 29 to enter only the lower end of the piston plate 30. Thus, when the piston plate 30 moves back, the gas in the piston chamber 32 is forced into the first one-way valve 33. The elastic pressure plate 9 slides on the tube 29 and is relatively sealed with the tube 29. Through the cooperation between the two one-way valves and the elastic pressure plate 9, the piston rod 31 can be continuously pressed to continuously supply gas to the first pressure chamber 8. When the elastic pressure plate 9 moves to the limit position, the pressure in the first pressure chamber 8 can supply 100ML of water to the nozzle assembly 7.
[0031] The water pipe assembly 6 includes a housing 35, a water pipe body 36, an inner pipe 37, a winding rod 38, and a spring 39. The water pipe body 36 and the winding rod 38 are both housed within the housing 35, which is located on the upper part of the cover 2. One end of the water pipe body 36 is fixed to the winding rod 38, and the other end extends out of the housing 35 and is fixed to the nozzle assembly 7. After the winding rod 38 rotates, the water pipe body 36 winds around it. A recess 40 is provided at the top of the cover 2, and the spring 39 is housed within the recess 40. A mounting hole 41 is also provided at the bottom of the recess 40. The winding rod 38 rotates within the mounting hole 41. One end of the spring 39 is fixed to the side wall of the settling tank 40, and the other end is fixed to the winding rod 38. A second flow channel 42 is also provided inside the winding rod 38. The water pipe body 36 is connected to the second flow channel 42. The inner pipe 37 is located on the bottom side of the tank cover 2 and has a third flow channel 43. The second flow channel 42 is connected to the third flow channel 43. The lower end of the inner pipe 37 extends to the bottom side of the water tank 1. The water flows from the third flow channel 43 to the second flow channel 42 and then enters the water pipe body 36, and then enters the first flow channel 19 from the water pipe body 36.
[0032] When the nasal irrigator is needed, pulling the nozzle assembly 7 will extend the water tube body 36 out of the outer casing 35. At this time, the spring 39 will generate elastic energy. When the nozzle assembly 7 is released, the elastic energy of the spring 39 will be released, and the water tube will be wound back onto the winding rod 38, thus completing the automatic winding function. The outer casing 35 is also equipped with a locking handle 44, which is located at the upper end of the winding rod 38 and is threaded to the outer casing 35. The bottom of the locking handle 44 abuts against the top surface of the winding rod 38. When it is necessary to lock the winding rod 38, the bottom of the locking handle 44 will press against the top surface of the winding rod 38 to lock the winding rod 38. This allows the water tube body 36 to be locked whenever it is pulled out to any length, and controls the time when the spring 39 rewinds the water tube body 36.
[0033] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
