Technical Field

[0001] The utility model relates to the technical field of nasal washers, in particular to a nasal washer valve and a nasal washer. Background Art

[0002] Nasal irrigation has been clinically proven to be an effective treatment for rhinitis and for alleviating various rhinitis symptoms. It is safe, has no side effects, and can be used long-term. A nasal irrigation device is a tool used to clean the nasal cavity. It typically uses pressure to deliver saline solution into the nostrils. The solution then flows through the nasal vestibule, sinuses, and nasal passages, bypassing the nasopharynx, and then exiting through one nostril or the mouth.

[0003] Currently, most nasal irrigation devices have non-self-locking valves. When a finger presses the button, the valve opens, but when the finger is released, it closes and does not remain open. Patients must press the button with their fingers, which is very inconvenient. Currently used self-locking valves are generally complex in structure, have high production and processing scrap rates, and are inefficient in assembly. They are prone to leakage during use, affecting normal nasal irrigation. To address these shortcomings, this application was proposed. Utility Model Content

[0023] The following description is intended only to disclose the present invention and to enable those skilled in the art to implement the present invention. The embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0024] Example 1:

[0025] A nasal wash valve, such as Figure 1 , including a shell 5, a valve body 6, an elastomer 4, a turntable 3, a button 1 and an end cover 2. This solution can realize the assembly of the valve through 6 components, with a simple structure, easy assembly, and reduced product raw material costs.

[0026] The button 1 is provided with an inner hole connected to the valve body 6. The button 1 is provided with an air hole 11 to achieve the ventilation effect of the nasal wash device after the valve is opened. The button 1 is provided with a plurality of pressing teeth 12 for pushing the guide teeth 31 to move in the guide groove 22.

[0027] The end cover 2 is nested inside the housing 5, as shown in FIG. Figure 5 A plurality of guide grooves 22 are evenly distributed on the inner wall of the end cover 2, and a slope is provided at the bottom of the guide groove 22.

[0028] Turntable 3 Figure 4 As shown, the turntable 3 has a through hole in the center, and the opposite ends of the turntable 3 and the button 1 are provided with wavy concave and convex contact surfaces. A plurality of guide teeth 31 are provided on the outer circumference of the turntable 3, and the top of the guide teeth 31 has an inclined surface, and the guide teeth 31 can move in the guide groove 22.

[0029] The elastic body 4 is a spring in this embodiment.

[0030] The shell 5 can be made of a relatively soft material with elastic deformation properties, such as silicone, PVC, PET, etc., to ensure the sealing of the valve and the nasal wash bottle; when the shell is inserted into the bottle, the shell 5 squeezes and locks the end cover 2, and the outer circumferential surface of the shell 5 is provided with a locking ridge 52 for engaging with the nasal wash bottle when installed, and the bottom of the shell 5 contacts the valve body 6 to achieve sealing.

[0031] A sealing ring 7 is mounted on the housing 5 for cooperating with the nasal washer bottle to achieve a further sealing effect.

[0032] like Figure 2The valve body 6 is arranged through the end cover 2, the elastomer 4, and the shell 5. The valve body 6 has a driving end 62 and a valve end 61. The driving end 62 can be engaged with the button 1. In this embodiment, the valve end 61 adopts a variable diameter structure, and the diameter gradually decreases from the end to the inside to form a valve end 61 with a fan-shaped cross section. The diameter of the hole at the end of the shell 5 is smaller than the maximum diameter of the valve end 61, so as to achieve a better sealing effect when closed.

[0033] The pressing teeth 12, the guide teeth 31, the guide grooves 22, and the wavy concave-convex contact surface form a pressing structure similar to that in a ballpoint pen. By pressing the button 1, the relative position of the guide teeth 31 and the end cover 2 is switched. The guide teeth 31 enter and exit the guide grooves 22, causing the guide teeth 31 of the turntable 3 to move between the guide grooves 22, thereby achieving the effect of extending the valve body 6 to open and locking it after opening. When the nasal irrigation device is placed upright, the valve body 6 can fall under the action of gravity to achieve a seal, preventing the liquid in the nasal irrigation device from flowing out.

[0034] The valve of this solution is easy to assemble. You only need to pass the valve body through the shell, put in the spring, turntable and button, press the button to lock the valve body, and then put on the end cover. The valve is easy to install into the bottle body. The valve is directly plugged into the hole at the bottom of the bottle. The shell has a locking ridge to avoid slipping. The installation process is simple and the assembly cost is reduced. The shell is designed with soft material and can directly achieve a sealing effect when in contact with the bottle body. After being installed in the bottle body, the bottle body squeezes the shell and the end cover will not come off. When in use, press the button to open the valve for ventilation, invert and squeeze the bottle body for nasal washing. When the valve is in the open state and the nasal wash bottle is placed upright, the valve will automatically close to prevent liquid from flowing out, thereby avoiding leakage.

[0035] Example 2:

[0036] On the basis of embodiment 1, a positioning structure 21 is provided on the end cover 2, such as Figure 3 The positioning structure 21 includes a plurality of positioning protrusions arranged along the circumference of the end cover 2. The positioning protrusions can play a positioning role. The positioning structure 21 also includes a positioning ridge portion. The positioning protrusions and the positioning ridge portion are respectively arranged at different axial positions of the end cover 2, and both play a positioning role.

[0037] The housing 5 is provided with a matching structure 51 which is an annular groove for accommodating the positioning protrusions and the positioning ridges, so as to facilitate non-directional installation.

[0038] A nasal irrigation device includes the nasal irrigation device valve of any of the above embodiments. The valve is installed at the bottom of the nasal irrigation device bottle. After pressing the button 1, the valve body 6 opens for ventilation. At the same time, the valve body 6 is self-locking. When the valve is in the open state, the nasal irrigation device bottle is placed upright, and the valve body 6 falls and automatically closes to prevent liquid from flowing out, thereby avoiding leakage caused by the valve not being closed.
