Description

Technical Field

[0001] The invention relates to a nasal irrigator with a water flow regulating function, belonging to the technical field of nasal irrigators. Background Art

[0002] A nasal rinser is a tool used to clean the nasal cavity. It usually uses a certain pressure (or airbag nasal rinser, or gravity such as a simple bottle type, or mechanical pressure such as an electric type) to send saline into the nostrils, flowing through the nasal vestibule (the part exposed outside the head), sinuses, nasal passages, bypassing the nasopharynx, or discharged from one nostril, or discharged from the mouth. Through the above paths, with the help of the bactericidal effect of the saline itself and the impact of the water flow, the pathogens and pollutants that have accumulated in the nasal cavity are discharged, so that the nasal cavity can restore its normal physiological environment, restore the self-detoxification function of the nasal cavity, and achieve the purpose of protecting the nasal cavity.

[0003] During the flushing process, the water supply is relatively fixed, and the liquid supply cannot be conveniently adjusted according to the size of the nasal cavity of different patients. As a result, the device cannot perform flushing work with different water supplies according to different populations and different degrees of disease severity, making the device less convenient to use.

[0004] Therefore, a nasal irrigator with water flow regulating function is proposed. Summary of the invention

[0005] In view of this, the present invention provides a nasal irrigator with a water flow regulating function to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0006] The technical solution of the present invention is achieved as follows: a nasal irrigator with a water flow regulation function, comprising a shell, the left side of the shell is connected to a liquid inlet pipe, the right side of the shell is connected to a liquid outlet pipe, the end of the liquid outlet pipe away from the shell is connected to a flushing nozzle, and an adjustment mechanism is arranged in the inner cavity of the shell, the adjustment mechanism comprises a mounting plate, a mounting block, a driven bevel gear, a liquid inlet hole and a liquid inlet hole, the mounting plate is fixedly installed in the inner cavity of the shell, the eight mounting blocks are all located on the right side of the mounting plate, the driven bevel gears are movably connected to the left side of the mounting plate, the surfaces of the eight mounting blocks are movably connected to connecting rods, the other ends of the four connecting rods are movably connected to movable blocks, the left sides of the four movable blocks are fixedly installed with blocking blocks, and the eight liquid inlet holes are all arranged on the surface of the mounting plate.

[0007] Further preferably, a screw rod is fixedly connected to the right side of the driven bevel gear, a screw block is threadedly connected to the surface of the screw rod, and the eight mounting blocks are fixedly mounted around the surface of the screw block.

[0008] Further preferably, a knob is movably connected to the top of the housing, and a driving bevel gear is fixedly connected to the bottom of the knob via a rotating shaft, and a surface of the driving bevel gear is meshed with a surface of the driven bevel gear.

[0009] Further preferably, a movable groove is opened on the right side of the mounting plate, and the left sides of the eight blocking blocks are slidably connected to the inner cavities of the eight movable grooves.

[0010] Further preferably, the eight liquid inlet holes are all opened on the left side of the inner cavities of the eight movable grooves, and the inner cavities of the liquid inlet holes are communicated with the inner cavities of the movable grooves.

[0011] Further preferably, a latch is inserted into the inner surface of the knob, and the bottom of the latch is inserted into the inner surface of the housing.

[0012] Further preferably, friction grooves are provided on the surface of the knob, and the friction grooves are arranged equidistantly in the circumferential direction.

[0013] Further preferably, a limiting frame is fixedly installed on the right side of the mounting plate, and the screw block is slidably connected to the surface of the limiting frame.

[0014] The embodiment of the present invention has the following advantages due to the adoption of the above technical solution:

[0015] 1. The present invention sets an adjustment mechanism, and drives the screw rod to rotate through the active bevel gear, so that the installation block drives the blocking block to move outward, so that the space through which water can pass through the liquid inlet hole is gradually reduced. When the diameter of the liquid inlet hole increases, the cross-sectional area increases, and the water output will increase at the same flow rate; conversely, the diameter of the liquid inlet hole decreases, the cross-sectional area decreases, and the water output decreases, so that the water output of the entire device can be freely adjusted, which is convenient for flushing different water supplies for patients with different sizes of nasal cavities and the severity of the disease, thereby improving the convenience of using the device.

[0016] 2. The present invention can limit the movement of the blocking block by setting a movable groove, so as to avoid the blocking block from being offset when moving, thereby affecting the adjustment of the cross-sectional area of ​​the liquid inlet hole. By setting the liquid inlet hole and the movable groove, it is convenient for the liquid to be injected smoothly through the inner cavity of the liquid inlet hole and the movable groove. By setting a latch, the position of the knob can be limited to avoid the knob from rotating due to accidental external collision, thereby affecting the adjustment of the cross-sectional area of ​​the liquid inlet hole. By setting a friction groove, the stability of medical staff in grasping the knob can be improved to avoid the medical staff wearing gloves and thus slipping when rotating the knob. By setting a limit frame, the movement of the screw block can be limited to avoid the screw block from being offset when moving, thereby affecting the adjustment of the cross-sectional area of ​​the liquid inlet hole.

[0025] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0026] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] like Figure 1-5As shown, an embodiment of the present invention provides a nasal irrigator with a water flow regulating function, including a shell 1, a liquid inlet pipe 3 is connected to the left side of the shell 1, a liquid outlet pipe 4 is connected to the right side of the shell 1, and a flushing nozzle 5 is connected to the end of the liquid outlet pipe 4 away from the shell 1. An adjusting mechanism 2 is arranged in the inner cavity of the shell 1, and the adjusting mechanism 2 includes a mounting plate 201, a mounting block 204, a driven bevel gear 208, a liquid inlet hole 211 and a liquid inlet hole 211. The mounting plate 201 is fixedly installed in the inner cavity of the shell 1, and eight mounting blocks 204 are all located on the right side of the mounting plate 201. The driven bevel gear 208 is movably connected to the left side of the mounting plate 201. The surfaces of the eight mounting blocks 204 are A connecting rod 205 is movably connected, and the other ends of the four connecting rods 205 are movably connected to movable blocks 206. The left sides of the four movable blocks 206 are fixedly installed with blocking blocks 207. Eight liquid inlet holes 211 are arranged on the surface of the mounting plate 201. The right side of the driven bevel gear 208 is fixedly connected to the screw rod 202, and the surface of the screw rod 202 is threadedly connected to the screw block 203. Eight mounting blocks 204 are fixedly installed around the surface of the screw block 203. The top of the shell 1 is movably connected to a knob 210, and the bottom of the knob 210 is fixedly connected to an active bevel gear 209 through a rotating shaft. The surface of the active bevel gear 209 is meshed with the surface of the driven bevel gear 208.

[0029] By setting the adjustment mechanism 2, the active bevel gear 209 drives the screw rod 202 to rotate, so that the installation block 204 drives the blocking block 207 to move outward, so that the space for water to pass through the liquid inlet hole 211 is gradually reduced. When the diameter of the liquid inlet hole 211 increases, the cross-sectional area increases, and the water output will increase at the same flow rate; conversely, the diameter of the liquid inlet hole 211 decreases, the cross-sectional area decreases, and the water output decreases, so that the water output of the entire device can be freely adjusted, which is convenient for flushing different water supplies for patients with different sizes of nasal cavities and the severity of the disease, thereby improving the convenience of using the device.

[0030] Example 2

[0031] like Figure 2-5 As shown, in one embodiment, movable grooves 214 are provided on the right side of the mounting plate 201, and the left sides of the eight blocking blocks 207 are slidably connected to the inner cavities of the eight movable grooves 214. The eight liquid inlet holes 211 are provided on the left side of the inner cavities of the eight movable grooves 214, and the inner cavities of the liquid inlet holes 211 and the inner cavities of the movable grooves 214 are interconnected. A latch 213 is inserted into the inner surface of the knob 210, and the bottom of the latch 213 is inserted into the inner surface of the shell 1. The surface of the knob 210 is provided with friction grooves 212, and the friction grooves 212 are arranged equidistantly in the circumferential direction. A limit frame 215 is fixedly installed on the right side of the mounting plate 201, and the screw block 203 is slidably connected to the surface of the limit frame 215.

[0032] By setting the movable groove 214, the movement of the blocking block 207 can be limited to avoid the blocking block 207 from being offset when moving, thereby affecting the adjustment of the cross-sectional area of ​​the liquid inlet hole 211. By setting the liquid inlet hole 211 and the movable groove 214, the liquid can be smoothly injected through the inner cavity of the liquid inlet hole 211 and the movable groove 214. By setting the latch 213, the position of the knob 210 can be limited to avoid the knob 210 from being accidentally hit by the outside, so that The knob 210 may rotate, which in turn may affect the adjustment of the cross-sectional area of ​​the liquid inlet hole 211. By providing the friction groove 212, the stability of the medical staff when grasping the knob 210 can be improved, and the medical staff can avoid slipping when rotating the knob 210 due to wearing gloves. By providing the limit frame 215, the movement of the screw block 203 can be limited, and the screw block 203 can be prevented from deviating when moving, thereby affecting the adjustment of the cross-sectional area of ​​the liquid inlet hole 211.

[0033] When the present invention is working: according to the liquid flow required for nasal irrigation of the patient, the gripping knob 210 is rotated, and the knob 210 synchronously drives the active bevel gear 209 to rotate, so that the driven bevel gear 208 drives the screw rod 202 to rotate, and as the screw rod 202 rotates, the screw block 203 moves to the left, and the mounting block 204 drives the connecting rod 205 to swing, and the connecting rod 205 pushes the movable block 206 and the blocking block 207 to move outward, and the blocking block 207 gradually blocks the cross-sectional area of ​​the liquid inlet hole 211. When the flow reaches the required requirement, the knob 210 is limited by the latch 213, thereby completing the adjustment of the liquid flow.

[0034] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of various changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
