Description

Technical Field

[0001] This utility model belongs to the field of medical and nursing technology, specifically relating to a novel nasal irrigator structure. Background Technology

[0002] A nasal irrigator is a tool used to clean the nasal cavity. It typically uses pressure (either a bag-type nasal irrigator, a simple bottle-type irrigator using gravity, or a mechanical pressure such as an electric one) to deliver saline solution into the nostrils. The solution flows through the nasal vestibule (the part exposed outside the head), sinuses, and nasal passages, bypassing the nasopharynx, and exiting either through one nostril or the mouth. Through this pathway, the saline solution's own bactericidal properties and the force of the water flow remove accumulated pathogens and impurities from the nasal cavity, thereby restoring the nasal cavity's normal physiological environment and self-detoxification function, ultimately protecting the nasal cavity.

[0003] Traditional nasal spray irrigators primarily use an atomizer to deliver a mist of cleaning solution, which then collects on the nasal mucosa to form a water flow, thus cleaning and caring for the nasal cavity. The advantage of this method is that the cleaning process is gentler, less likely to damage the nasal mucosa or cause choking. However, its disadvantages include the waste liquid flowing down and mixing with the medication, contaminating it, and / or dripping onto the environment or clothing, resulting in waste and contamination. Therefore, solving these technical problems is a pressing issue that needs to be addressed in this industry. Summary of the Invention

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 12As shown in the figure, this utility model embodiment provides a novel nasal irrigator structure, specifically including, from top to bottom, a nasal irrigator head assembly 300 for atomizing and cleaning the nasal cavity, a waste liquid chamber assembly 100 for collecting waste liquid flowing back during nasal cavity cleaning, and a nasal irrigator body 200 for providing nasal cavity cleaning and various connecting pipes. The nasal irrigator head assembly 300 is fixedly installed on the waste liquid chamber assembly 100, and the bottom of the waste liquid chamber assembly 100 is detachably installed on the nasal irrigator body 200. In this embodiment, the nasal irrigator head assembly 300, the waste liquid chamber assembly 100, and the nasal irrigator body 200 can all be detachably connected, and sealing rings (not shown in the figure) are provided at the connection points of the three to ensure the airtightness between the nasal irrigator head assembly 300, the waste liquid chamber assembly 100, and the nasal irrigator body 200. A dust cover 500 is fixedly connected to the top of the nasal irrigator head assembly 300, which is used for dust protection when the nasal irrigator is not in use.

[0023] Please see Figures 2 to 12 As shown, the waste liquid chamber assembly 100 specifically includes a secondary housing 11, within which a waste liquid chamber 12 is disposed. A nasal irrigation head assembly 300 is disposed above the waste liquid chamber 12, and an atomizing assembly 13 is disposed within the waste liquid chamber 12. The nasal irrigator body 200 specifically includes a main housing 21, within which a detachably connected liquid storage chamber assembly 22 is disposed. A water pump 23 is disposed within the main housing 21. The inlet of the water pump 23 is connected to the interior of the liquid storage chamber assembly 22, and the outlet of the water pump 23 is connected to the atomizing assembly 13. The water path of the atomizing assembly 13 passes through the waste liquid chamber 12 and extends into the interior of the nasal irrigation head assembly 300.

[0024] Specifically, in this embodiment, a detachably connected liquid storage chamber assembly 22 is provided inside the main housing 21, and a water pump 23 is provided inside the main housing. The output port of the water pump 23 is connected to the inside of the nasal irrigation head assembly 300 through the atomizing assembly 13. In this embodiment, the water pump 23 pumps the nasal irrigation saline stored in the liquid storage chamber assembly 22 to the atomizing assembly 13. The nasal irrigation saline forms atomized particles in the atomizing assembly 13 and is finally sprayed out through the nasal irrigation head assembly 300. This can achieve atomized cleaning of nasal mucus and / or nasal discharge in the nasal cavity, thus completely cleaning out the nasal mucus and nasal discharge in the nasal cavity.

[0025] Please see Figure 4 and Figure 5As shown, the liquid storage chamber assembly 22 specifically includes a vertically arranged liquid storage 221 for holding nasal irrigation saline solution, and a support base 222 is fixedly connected to the bottom of the liquid storage 221. The size of the support base 222 is adapted to the shape of the bottom of the main housing 21. Several magnetic magnets 223 are installed on the top of the support base 222 (in this embodiment, three or four magnetic magnets 223 are evenly arranged on the top of the support base 222). A storage cavity 224 is provided at the bottom of the support base 222, and a handle 225 is rotatably connected inside the storage cavity 224. When not in use, the handle 225 is stored in the storage cavity 224. When in use, the handle 225 is unscrewed from the storage cavity 224, and the liquid storage chamber assembly 22 is detached from the nasal irrigator body 200 through the handle 225. The liquid storage 221 has a semi-arc structure that matches the shape of the main shell 21. The multiple magnetic magnets 223 can tightly attach the support base 222 to the bottom of the main shell 21. Specifically, in this embodiment, this adsorption-type liquid storage chamber assembly 22 can be easily detached from the main shell 21.

[0026] Please see Figure 6 and Figure 7As shown, a mounting frame 26 is provided inside the main housing 21. Water pump mounting cavities 261 for housing the water pump 23 are respectively provided on the left and right sides of the mounting frame 26. A battery mounting cavity 262 is provided on the back of the mounting frame 26, and a battery 24 is fitted inside the battery mounting cavity 262. A panel mounting cavity 263 for mounting the control panel 25 is provided on the front of the mounting frame 26. A button 27 is electrically connected to the control panel 25. The control panel 25 and the water pump 23 are electrically connected to the battery 24. Specifically, in this embodiment, the mounting frame 26 can tightly fix the water pump 23 and the battery 24, making the overall structure of the nasal irrigator more compact and reducing the space occupied. In this embodiment, the right side of the liquid storage 221 is tightly fitted and snapped into the left side of the mounting frame 26 inside the main housing 21. This increases the stability of the mounting frame 26, preventing it from shaking or shifting during use, thus improving the stability and reliability of the nasal irrigator and ensuring its normal operation. Furthermore, the four-sided arc-shaped structure of the mounting frame 26 reduces the overall space occupied by the frame, making the overall structure of the nasal irrigator more compact. It also avoids interference between the water pump 23 and the battery 24, while modularizing the water pump 23 and battery 29 for easier assembly and improved stability. A first water inlet pipe 264 and a first water outlet pipe 265 are provided at the top of the mounting frame 26, respectively connected to the inlet and outlet of the water pump 23. Specifically, in this embodiment, the water channels (first water inlet pipe 265 and first water outlet pipe 266) on the mounting frame 26 provide a simpler and clearer connection to the water system within the main housing 21.

[0027] Please see Figure 8As shown, a connecting part 400 is provided between the waste liquid chamber assembly 100 and the nasal irrigator body 200. The connecting part 400 includes a connecting body 41, a connecting cavity 42 is provided inside the connecting body 41, and a connecting thread 43 is provided on the inner wall of the connecting cavity 42. The waste liquid chamber assembly 100 is connected to the connecting part 400 through the connecting thread 43. This threaded connection allows for a detachable connection between the lower part of the waste liquid chamber assembly 100 and the connecting part 400. Several elastic retaining strips 44 are provided on the outer circumferential surface of the connecting body 41 (in this embodiment, four elastic retaining strips 44 are provided along the outer circumferential surface of the connecting body 41). The four elastic retaining strips 44 are engaged with the inner top of the nasal irrigator body 200, so that the top of the nasal irrigator body 200 is flush with the top of the connecting part 400 after installation. An arc-shaped groove (not shown in the figure) for placing an elastic sealing ring is provided on the outer circumferential surface inside the connecting body 41. The arc-shaped groove is located above the elastic retaining strip 44, thus ensuring the sealing of the connecting part 400 and the nasal irrigator body 200 when they are installed. A connecting port 45 is provided at the bottom of the connecting cavity 42, and the first water outlet pipe 265 passes through the connecting port 45 and connects to the atomizing component 13.

[0028] Please see Figure 9 and Figure 10 As shown, the atomizing component 13 specifically includes a slender atomizing tube 131 extending along the water path. A limiting ring 132 is fixedly connected to the lower part of the atomizing tube 131. During installation, the bottom of the limiting ring 132 contacts the bottom of the waste liquid chamber 12 to limit the atomizing tube 131. A locking groove 133 is provided at the lower part of the limiting ring 132. A locking cavity 121 matching the locking groove 133 is provided at the middle of the bottom of the waste liquid chamber 12. During installation, the locking groove 133 is rotated and locked into the inside of the locking cavity 121 to fix the atomizing tube 131 to the bottom of the waste liquid chamber 12. An atomizing nozzle 134 is provided at the top of the atomizing tube 131, and the atomizing nozzle 134 matches the nasal rinse head component 300. The nasal irrigation saline solution stored in the reservoir assembly 22 is pumped by the water pump 23 into the nebulizer tube 131. The saline solution forms atomized particles within the nebulizer tube 131 and is finally sprayed out through the nasal irrigation head assembly 300. This atomized saline solution effectively cleanses nasal mucus and / or nasal discharge. A limiting strip 135 is provided at the lower part of the nebulizer tube 131. The limiting strip 135 and the mounting groove 133 are respectively located on the upper and lower sides of the limiting ring 132. The limiting strip 135 limits the installation of the return assembly 14. Further optimizing this embodiment, the height of the nebulizer assembly 13 is greater than the height of the top of the waste liquid chamber 12, and the top of the nebulizer assembly 13 extends into the interior of the nasal irrigation head assembly 300. This ensures that the nebulizer tube 131 is long enough to fully atomize the saline solution inside.

[0029] Please see Figure 11 As shown, a reflux assembly 14 is provided between the nasal irrigation head assembly 300 and the waste liquid chamber 12. The reflux assembly 14 is fixedly installed on the top of the waste liquid chamber 12. The reflux assembly 14 specifically includes a reflux chamber 141, with a through-hole 142 at the bottom of the reflux chamber 141. The atomizing assembly 13 passes through the through-hole 142 and extends into the interior of the nasal irrigation head assembly 300. Reflux gaps 143 are provided around the through-hole at the bottom of the reflux chamber 141. In this embodiment, the reflux assembly 14 enables separation between the nasal irrigation head assembly 300 and the waste liquid chamber 12. Simultaneously, the reflux gaps 143 allow the waste liquid flowing back from the nasal irrigation head assembly 300 to leak downwards, returning the waste liquid to the waste liquid chamber 12.

[0030] Please see Figure 12 and Figure 13 As shown, the nasal irrigation head assembly 300 includes a bottom base 301, which is snapped onto the top of the reflux assembly 14. A nasal spray plug 302 is disposed on the bottom base 301, and a nasal irrigation spray hole 303 is disposed on the top of the nasal spray plug 302. The nasal irrigation spray hole 303 corresponds to the atomizing spray hole 134 on the top of the atomizing assembly 13. A plurality of return holes 304 are disposed along the inner edge of the nasal irrigation spray hole 303, and the return holes 304 are connected to the reflux cavity 141 below them. An annular baffle 305 is disposed on the outer circumferential surface of the nasal spray plug 302. In this embodiment, the nasal spray plug 302 has a hollow interior design. The nasal spray plug 302 is fitted onto the atomizing spray hole 134 on the top of the atomizing tube 131, aligning the nasal irrigation spray hole 303 with the atomizing spray hole 134. The water inlet direction can be achieved through the atomizing spray hole 134 (see...). Figure 13 The water inlet method is indicated by the arrow inside the nasal spray plug 302. The design of the nasal spray nozzle 303 prevents the nasal tip from being inserted into the nostril and causing injury, thus enhancing user comfort. After the atomized particles of saline solution are sprayed from the nasal spray nozzle 303 of the nasal spray plug 302 and cleanse the nasal cavity, these particles will re-aggregate into a water flow and return to the waste liquid chamber 12 through the return hole 304 (see...). Figure 13 (The arrow inside the nasal spray plug 302 indicates the reflux method). In this embodiment, by providing an annular baffle 305 on the outer circumferential surface of the nasal spray plug 302, it is possible to prevent a very small amount of waste liquid after nasal cavity cleaning from overflowing onto the bottom base 301.

[0031] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
