Description

Technical Field

[0001] The utility model relates to the field of medical physiotherapy devices, in particular to a nasal douche. Background Art

[0002] In recent years, due to the influence of various factors such as environmental pollution, climate change, and living habits, the nasal health problems of modern people have become increasingly prominent. Harmful substances such as dust, bacteria, and viruses accumulated in the nasal cavity may cause diseases such as rhinitis and sinusitis, affecting people's respiratory and olfactory functions, and even leading to more serious health problems. Therefore, people's attention to nasal health and the demand for nasal cavity cleaning are increasing. To solve the above nasal health problems, the application of nasal douches is becoming more and more common. The conventional nasal douche bottle body does not have an air pressure valve, so it is easy to cause the imbalance of internal and external air pressures during the use of the nasal douche. As a result, a large amount of air is inhaled into the nasal douche from the nozzle when the bottle body rebounds. At the same time, due to the internal and external pressure difference during inhalation, the air is fully mixed with the cleaning liquid in the nasal douche, thus polluting the cleaning liquid.

[0003] The publication (announcement) number of the comparative document: CN208927025U, the publication (announcement) date: June 4, 2019, relates to a nasal douche, including a bottle body and an air inlet valve. An air inlet hole is provided on the bottle body, and the air inlet valve is installed at the air inlet hole. The air inlet valve includes a pressing member arranged outside the bottle body, a sealing member arranged inside the bottle body, a connecting rod connecting the pressing member and the sealing member, and an elastic member arranged between the bottle body and the pressing member. Although the above comparative document proposes a nasal douche with an air inlet valve, the air inlet valve of the nasal douche is installed on an arc surface, and its airtightness is not strong, and it is easy to leak and be damaged. Therefore, the utility model proposes a nasal douche with a flat mounting platform to solve the problems of poor sealing effect and inconvenient cleaning and installation existing in the above nasal douche. Summary of the Utility Model

[0004] The utility model aims to solve the problem of poor sealing effect at the airtight part of the nasal douche in the above-mentioned prior art, and proposes a nasal douche.

[0005] To achieve the above purpose, the solution provided by the utility model is: a nasal douche, including a bottle body and a liquid suction tube. An installation platform is provided at the bottom of the bottle body. The installation platform is a flat surface provided with an installation hole, and the installation platform is connected to an airtight valve. The airtight valve includes a fixing member, a spring, a sealing gasket, and a piston. A fixing groove is provided on the outer surface of the fixing member. The longitudinal section of the fixing groove is a rectangle with one side open. The fixing groove is fitted into the edge of the installation platform, and its three sides are closely attached to the edge of the installation platform. By setting a flat mounting platform and simultaneously setting a fixing groove on the outer surface of the fixing member of the airtight valve, and embedding the flat mounting platform into the fixing groove of the fixing member, the sealing performance of the airtight valve is enhanced, and the possibility of potential safety hazards caused by air leakage of the airtight valve is reduced.

[0006] Preferably, the bottle body is made of a flexible material and has a cylindrical structure with a concave middle part and convex ends on the side surface. The top of the bottle body made of the flexible material is provided with a thread at the bottle mouth. Choosing a flexible material as the bottle body facilitates squeezing the bottle body. The concave columnar structure in the middle of the bottle body is convenient for grasping, and the thread at the bottle mouth is used to connect the liquid suction pipe.

[0007] Preferably, the middle of the bottom of the bottle body is concave inward, and the installation platform is arranged on the concave plane. The design of the concave bottom in the middle enhances the structural stability of the bottle body. The installation platform is arranged on the plane, which reduces the possibility of gaps in the connection between the installation platform and the fixing member of the airtight valve, and is used to enhance the airtightness of the nasal washer.

[0008] Preferably, the fixing member of the airtight valve is a cylindrical structure with open ends at both ends, and a first fixing block with an annular cross-section is arranged inside it. The upper and lower surfaces of the first fixing block are horizontally parallel. The piston passes through the center of the ring and is fixed. The fixing member is used to connect the bottle body and the piston of the airtight valve, and ensures that the installation platform plane, the surface of the fixing member, and the surface of the gasket are all horizontally parallel, thus achieving the effect of enhancing the sealing performance.

[0009] Preferably, one end of the piston is provided with a gasket groove concave inward, and the other end is provided with a pressing component. The piston with the gasket groove is used to control the internal and external pressures of the bottle body. After the piston is inserted into the fixing member, the gasket is embedded in the gasket groove, which is used to control the opening and closing of the airtight valve, and further control the use of the nasal washer.

[0010] Preferably, the spring is sleeved outside the piston, and the two ends of the spring are respectively attached to the pressing component and the upper surface of the first fixing block. A spring is arranged between the pressing component and the upper surface of the first fixing block of the fixing member. The spring abuts against the pressing component and the upper surface of the first fixing block, providing pressure for the sealing of the nasal washer.

[0011] Preferably, one surface of the gasket is a horizontal plane, and the other surface is an inclined plane with a higher side near the groove and a lower side far from the groove. The horizontal plane of the gasket fits against the lower surface of the first fixing block. The gasket and the first fixing block are closely attached when the nasal washer is not working, which is used to prevent gas from entering the bottle body of the nasal washer and causing the nasal washer to be unable to be normally closed for use. Setting the other surface of the gasket as an inclined plane can effectively distinguish the inner and outer surfaces. At the same time, when the liquid in the bottle body is relatively full, the inclined plane setting can reduce the fluid resistance received by the gasket when pressing the piston, facilitating the use of the nasal washer.

[0012] Preferably, the liquid suction pipe is connected to the nozzle, and the connection part between the liquid suction pipe and the nozzle is an acute-angle bending structure. The top of the nozzle is provided with a number of liquid outlet holes. Setting the connection part between the liquid suction pipe and the nozzle as a bending structure can effectively buffer the outflow of the cleaning liquid, avoiding nasal cavity choking caused by too fast a flow rate. At the same time, the acute-angle bending structure makes the bottle body inclined upward when the nozzle is placed in the nasal cavity, which is convenient for the user to grasp and control the switch of the nasal washer.

[0013] The beneficial effects of the present utility model are as follows:

[0014] Installation and maintenance are more convenient. Installing the airtight valve on the flat installation table makes the disassembly and maintenance of the nasal washer more convenient. Since the airtight valve of the nasal washer is installed on the platform, there is no need to consider the air leakage and liquid leakage problems caused by the non-tight fit between the airtight valve and the bottle body, thereby reducing the cleaning difficulty of the nasal washer.

[0015] Reduce the risk of leakage. Compared with the arc surface installation, the flat surface installation of the airtight valve reduces the risk of leakage. When installing on the arc surface, due to the irregular shape, the sealing surface may be subjected to uneven pressure distribution, thereby increasing the risk of leakage. While the flat surface installation can better ensure the uniform force on the sealing surface and reduce the possibility of leakage.

[0016] Therefore, the present utility model reduces the installation difficulty of the nasal washer, enables the nasal washer to extend its service life through cleaning, and at the same time, the airtight valve that is convenient to clean reduces the possibility of the airtight valve contaminating the cleaning liquid.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The specific embodiments of the present utility model will be described in detail below. It should be noted that the embodiments described here are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the following embodiments, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] This embodiment provides a nasal washer, the structure of which is as shown in Figure 1 、 Figure 2, including a bottle body 10 and a liquid suction tube 20. The bottom of the bottle body 10 is provided with a mounting platform 11. The mounting platform 11 is a plane with a mounting hole, and the mounting platform 11 is connected to an airtight valve 30. The airtight valve 30 includes a fixing member 31, a spring 32, a sealing gasket 33, and a piston 34. The outer surface of the fixing member 31 is provided with a fixing groove 311, and the fixing groove 311 is fitted into the edge of the mounting platform 11.

[0024] The present utility model provides a nasal irrigation device. Compared with the existing nasal irrigation devices, the airtight valve 30 of the nasal irrigation device provided by the present utility model has a stronger installation sealing property. During actual use, the airtight valve 30 is installed on the flat mounting platform 11 at the bottom of the bottle body 10. When pressing the airtight valve 30, the mounting platform 11 at the bottom of the bottle can be evenly stressed, reducing the possibility of damage to the nasal irrigation device and the risk of leakage. At the same time, since the airtight valve 30 is installed on a horizontal plane, it is easier to observe and operate the airtight valve 30, facilitating the disassembly and daily cleaning of the airtight valve 30.

[0025] In one embodiment, the bottle body 10 is a bottle body made of a flexible material. The bottle body made of a flexible material is a cylindrical structure with a middle concave and two ends convex on the side surface. The top opening of the bottle body made of a flexible material is provided with a thread 12. The bottle body 10 is set as a cylinder with a smaller middle diameter for convenient grasping, thereby facilitating the user to operate and press the airtight valve 30 of the nasal irrigation device. The thread 12 is provided at the opening and is spirally connected with the thread on the liquid suction tube 20 to increase the stability of the connection.

[0026] In one embodiment, the middle of the bottom of the bottle body 10 is recessed inward into the bottle. The mounting platform 11 is arranged on the recessed plane. The inwardly recessed part can enhance the strength and stability of the overall structure of the bottle body 10. At the same time, different from the prior art where the bottom recess of the bottle is set as an arc structure, a flat mounting platform is provided at the center of the recess. Installing the airtight valve on the mounting platform can effectively avoid the problem that the nasal irrigation device cannot be placed vertically due to the protrusion of the airtight valve.

[0027] In one embodiment, the fixing member 31 of the airtight valve 30 is a cylindrical structure with unsealed ends, and a first fixing block 312 with a circular cross-section is provided inside the fixing member 312. The upper and lower surfaces of the first fixing block 312 are horizontally parallel, and the piston 34 is fixed through the center of the circular ring. The upper half cavity of the fixing member 31 of the airtight valve 30 that contacts the air is longer than the lower half cavity placed in the bottle body 10, and the lower half cavity is set shorter. Since the upper part is covered with a spring 32 after the piston 34 passes through, the spring 32 is deformed after receiving the pressing pressure, and the deformation amount is equal to the advancement distance of the piston 34 in the bottle body 10, that is, the sealing gasket 33 and the first fixing block 312 are spaced apart from each other. The advancement distance between the two, since the diameter of the sealing gasket 33 is slightly smaller than the diameter of the first fixing block 312, when the airtight valve 30 is pressed from the initial state, only a small gap is generated between the sealing gasket 33 and the first fixing block 312, so that the bottle body 10 is not connected smoothly with the outside world. At this time, the flow rate of the cleaning liquid flowing outward through the liquid pipette 20 is slow; when the airtight valve 30 is pressed until the sealing gasket 33 completely passes through the fixing member 31, the air in the bottle body 10 and the outside world circulate smoothly, and the flow rate of the cleaning liquid is accelerated. Therefore, if the cavity in the lower half is set longer, the bottle body 10 cannot be connected smoothly with the outside world, so that the liquid discharge of the nasal wash device is slow, affecting the user's experience.

[0028] In one embodiment, a sealing gasket groove 341 is provided at one end of the piston 34, and a pressing component 342 is provided at the other end. The sealing gasket groove 341 is recessed inward, so that the sealing gasket 33 and the piston 34 can be tightly fitted, thereby enhancing the sealing performance of the airtight valve 30. The diameter of the pressing component 342 is slightly larger than that of the piston 34, so as to facilitate exertion of force when pressing.

[0029] In one embodiment, the spring 32 is sleeved on the outside of the piston 34, and the two ends of the spring 32 respectively abut against the pressing component 342 and the upper surface of the first fixed block 312. The spring 32 is in a slightly compressed state between the pressing component 342 and the first fixed block 312, thereby providing elastic force to resist the pressing component 342 and the first fixed block 312, so that the sealing pad 33 can fit tightly against the first fixed block 312, and a closed environment can be provided when the nasal washer is not in use.

[0030] In one embodiment, one surface of the sealing pad 33 is a horizontal plane, and the other surface is an inclined plane with a high side close to the groove and a low side away from the groove. The horizontal plane of the sealing pad 33 abuts against the lower surface of the first fixing block 312. The sealing pad 33 as a horizontal plane can effectively prevent the nasal washer from not working properly due to air leakage of the airtight valve 30, thereby improving the sealing effect of the airtight valve. The other surface of the sealing pad 33 is set as an inclined plane to reduce fluid resistance and facilitate pressing of the airtight valve.

[0031] In one embodiment, the liquid suction pipe 20 is connected to the nozzle 40. The connecting part of the liquid suction pipe 20 and the nozzle 40 is an acute-angle bending structure. A plurality of liquid outlet holes are provided at the top of the nozzle 40. The liquid suction pipe 20 is provided with an acute-angle bend, which can effectively control the flow rate of the cleaning liquid and avoid choking when using the cleaning liquid with too fast a flow rate. At the same time, the acute-angle bend allows the bottle body 10 of the nasal washer to be held obliquely, facilitating the user to operate the nasal washer. The nozzle 40 is provided with 3 to 5 small liquid outlet holes, which can control the uniform outflow of the cleaning liquid.

[0032] In one embodiment, the nasal washer selects a single-hole nozzle 40 for more direct cleaning.

[0033] When the nasal washer is not working, the airtight valve 30 is in a closed state. As Figure 3 shown, at this time, the sealing gasket 33 is in a state of fitting the first fixing block 312, and the air inside and outside the nasal washer is not conducted, and the cleaning liquid in the bottle body 10 cannot be poured out.

[0034] When the nasal washer is working, the airtight valve 30 is pressed, and the airtight valve 30 is in an open state. As Figure 4 shown, at this time, the piston 34 is pressed into the bottle body 10, the spring 32 is in a compressed state, the sealing gasket 33 leaves the first fixing block 312, the air outside the nasal washer enters the bottle body 10, and the cleaning liquid flows out from the nozzle 40.

[0035] This embodiment proposes a nasal washer. By providing a flat mounting platform at the bottom of the bottle body, the airtight valve of the nasal washer and the bottle body can be closely fitted, solving the problems of poor sealing performance and difficult disassembly and cleaning of the existing nasal washer with an air valve, achieving the effects of enhancing the sealing performance of the nasal washer, reducing the risk of pollution of the cleaning liquid, and prolonging the service life of the nasal washer.

[0036] The above shows and describes the basic features, principles and advantages of the present invention. It should be noted that the present invention is not limited by the above embodiments, but only some embodiments. Without departing from the spirit and scope of the present invention, several improvements and supplements made are regarded as the protection scope of the present invention.
