Description

Technical Field

[0001] The utility model relates to the technical field of nasal irrigators, in particular to a nasal irrigator capable of preventing reflux of irrigating liquid. Background Art

[0002] A nasal irrigator is a device used to clean and rinse the nasal cavity, also known as a nasal wash pot or nasal wash bottle. It is usually used to treat nasal problems such as sinusitis, allergic rhinitis, nasal congestion, rhinovirus infection, and relieve allergic symptoms and remove allergens. Publication No. CN219538875U discloses a nasal irrigator, including a tank body, which is the main storage part of the nasal irrigator. The tank body is made of rubber, and a temperature controller is installed on one side of the inside, a heating plate is installed at the bottom of the inside of the tank body, and a tank cover is meshed and connected to the top of the tank body. The utility model overcomes the shortcomings of the prior art. By setting a temperature controller, a temperature control monitor and a heating plate, the operator can adjust the temperature control monitor. The temperature value is set at a temperature suitable for water temperature. The temperature control monitor controls the temperature through the heating plate to make the interior at a suitable water temperature. When the internal temperature exceeds the set temperature value, the temperature controller transmits a signal to the temperature control monitor to stop the heating plate from running, thereby improving the user's comfort. However, the nasal spray tube lacks a backflow prevention structure, and it is impossible to prevent the irrigating fluid from flowing back into the interior of the tank when medical staff operate the nasal irrigator. The refluxed irrigating fluid may contain impurities such as bacteria, which may easily contaminate the irrigating fluid inside the tank. Therefore, it needs to be improved. Utility Model Content

When the user releases the pressure on the clamping sheet 8, the elasticity of the spring A10 and the spring B11 is used to make the slide bar 5 drive the clamping block 7 to move upward.

[0025] See also Figure 1-5The slide bar 5 is slidably connected to the bottle body 1, and the movement of the clamping plate 8 drives the slide bar 5 to slide. The block 7 is inserted at the bottom of the connecting pipe 2, and the bottom end of the connecting pipe 2 is blocked by the block 7 to prevent the flushing liquid from flowing back from the connecting pipe 2 to the inside of the tank body. The upper surface of the clamping plate 8 is fixedly connected with an anti-slip pad 13, and the upper surface of the bottle body 1 is symmetrically fixed with a soft pad 12. The ends of the spring A10 and the spring B11 close to the bottle body 1 are fixedly connected to the soft pad 12, and the soft pad 12 has an anti-wear protection effect on one end of the spring A10 and the spring B11. The outer surface of the bottle body 1 is fixedly installed with an anti-slip outer ring 14, and the anti-slip outer ring 14 is provided with rounded corners. When the user holds the bottle body 1 and presses the clamping plate 8, the anti-slip outer ring 14 has an anti-slip effect on the hand.

[0026] Embodiment 2

[0027] See also Figure 4 , 5 A slider 16 is fixedly connected to the surface of the movable block 6, and an arc-shaped slide groove 15 is opened on the inner wall of the bottle body 1. When the slide rod 5 drives the movable block 6 to move, the slider 16 slides in the arc-shaped slide groove 15, making the movement of the movable block 6 more stable, thereby preventing the block 7 from being difficult to insert into the bottom end of the connecting pipe 2 when moving upward. The slider 16 is slidably connected to the arc-shaped slide groove 15, and the slider 16 is provided with rounded corners. The setting of the rounded corners helps the slider 16 to slide quickly in the arc-shaped slide groove 15.

[0028] Working principle: When the user uses the nasal irrigator, the user holds the bottle body 1 and presses the pressing plate 8 downward with the fingers. The anti-skid pad 13 can increase the friction between the fingers and the surface of the pressing plate 8. Then the slide bar 5 slides in the limiting hole 4, and the slide bar 5 drives the block 7 to move downward. The spring A10 and the spring B11 are then compressed, and the slider 16 moves downward in the arc-shaped slide groove 15 until the block 7 is completely separated from the bottom end of the connecting tube 2. Thus, the clean flushing liquid in the bottle body 1 can be pumped from the connecting tube 2 to the flushing nozzle 3 for the patient. The nasal irrigator can be used for flushing. When the user releases the pressure on the clamping plate 8, the slide bar 5 slides in the limiting hole 4, and the slider 16 moves upward in the arc-shaped slide groove 15. The elasticity of the spring A10 and the spring B11 is used to make the slide bar 5 drive the movable block 6 and the card block 7 to move upward, so that the card block 7 blocks the bottom end of the connecting tube 2, thereby blocking the flushing liquid and preventing the flushing liquid from flowing back from the connecting tube 2 to the inside of the tank body, thereby avoiding the reflux liquid from contaminating the clean flushing liquid inside the tank body.
