Description

Technical Field

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

[0002] A nasal irrigation device is a tool used to clean the nasal cavity. It typically uses a certain amount of pressure to deliver saline solution into the nostrils. The solution then flows through the nasal vestibule, sinuses, and nasal passages, bypassing the nasopharynx and exiting either one nostril or the mouth. Through these pathways, the saline solution's inherent bactericidal properties and the impact of the water flow expel accumulated pathogens and dirt from the nasal cavity, restoring the nasal cavity to its normal physiological environment and restoring its self-detoxification function, thereby protecting the nasal cavity. Clinically, using a nasal irrigation device to clean the nasal cavity has been shown to not only provide health benefits but also have therapeutic effects on conditions such as allergic rhinitis and sinusitis.

[0003] There are many different types of nasal rinsers on the market: simple bottle-type, handheld airbag-type, and electric nasal rinsers. Each of the three common nasal rinsers has its own advantages and disadvantages:

[0004] 1. The working principle of a simple bottle-type nasal washer is to rely on the inversion of the bottle, thereby utilizing the gravity of the water itself and the movement of the head to perform flushing, which is inconvenient to use.

[0005] 2. Handheld airbag nasal washers are commonly used in hospitals. They use hand-held pressure to release nasal wash liquid for cleaning. However, the pressure is difficult to control, resulting in the liquid flow being fluctuating. In addition, the waste liquid after flushing cannot be processed.

[0006] While electric nasal rinsers can maintain constant pressure, their drawback is the excessive water flow, making them unsuitable for people with nasal congestion. Furthermore, improper operation can easily cause choking or water to enter the ears, and they are also unsuitable for young children. The high cost and price of electric nasal rinsers also hinder their sales among the general public.

DETAILED DESCRIPTION

[0039] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0040] Reference Figure 1-3 As shown, the manual nasal wash device of the present invention comprises six major components: a bottle body 1, a bottle cap 2, a liquid outlet pipe 3, a one-way valve 4, a duckbill valve 5 and a silicone head 6; the bottle body 1 is used to store the liquid for nasal washing; the bottle cap 2 is arranged at the bottle mouth of the bottle body 1, and the bottle cap 2 is provided with a gas channel 21, and the gas channel 21 is connected to the bottle body 1; one end of the liquid outlet pipe 3 is connected to the bottle cap 2, and the other end of the liquid outlet pipe 3 extends into the bottle body 1, and the lower end of the liquid outlet pipe 3 directly extends to the bottom of the bottle body 1; the one-way valve 4 is arranged at the bottom of the bottle body 1 On the lid 2, the one-way valve 4 is used to open or close the gas channel 21; the duckbill valve 5 is connected to the inner cavity of the bottle body 1. The duckbill valve 5 is used to discharge the liquid medicine in the bottle body 1 and also prevents the liquid medicine from flowing back. The silicone head 6 is installed on the bottle cap 2. The duckbill valve 5 is installed on the silicone head 6. The silicone head 6 is provided with a liquid outlet hole 61, which is used to output the liquid medicine flowing out of the duckbill valve 5. A gap is provided between the opposing end surfaces of the silicone head 6 and the bottle cap 2. The gas channel 21 is connected to the outside atmosphere through the gap. The material of the liquid outlet pipe 3 and the silicone head 6 is both silicone, and the liquid outlet pipe 3 is a cylindrical hose.

[0041] The working principle of the manual nasal washer of the utility model when dripping liquid is as follows:

[0042] The bottle body 1 is made of a plastic material with good elasticity (such as PP, PE, etc.). Usually, when in use, there are two fluids in the bottle body (such as Figure 3 As shown), they are the added liquid and the residual gas respectively. When the bottle body 1 is squeezed by external force, the liquid in the bottle body 1 is affected by gravity and pressure, and the liquid flows into the liquid outlet pipe 3. At this time, the gas will move upward, as shown in FIG. Figure 6 As shown, due to the thrust generated by the gas flowing upward, the one-way valve 4 will be in a closed state (the one-way valve 4 is made of silicone rubber). At this time, the movable leaf of the one-way valve 4 cooperates with the step surface reserved by the bottle cap 2, thereby achieving a sealing effect.

[0043] When the channel at the one-way valve 4 is sealed, the squeezing force is continuously applied to the bottle body 1, and the positive pressure inside the bottle body 1 will increase accordingly. The liquid in the bottle body 1 will flow into the liquid outlet pipe 3 in a concentrated manner, and then flow to the duckbill valve 5 along the direction of the liquid outlet pipe 3. At this time, the duckbill valve 5 is pushed by the liquid, and the valve plate of the duckbill valve 5 undergoes plastic deformation, so that the duckbill valve 5 is in an open state to allow the liquid to pass through. Figure 7 shown.

[0044] When the manual nasal washer of the present utility model is reset:

[0045] The bottle body 1 is in a concave state after being subjected to pressure. In this state, when the pressure applied to the bottle body 1 is removed, the bottle body 1 will rebound to its original state (such as Figure 8 As shown), during the rebound process of the bottle body 1, the duckbill valve 5 is subjected to the reverse thrust of the fluid, so that it remains in a closed state (as shown in FIG. Figure 9 As shown), the one-way valve 4 is subjected to the reverse thrust of the fluid and remains open (as shown Figure 11 The two valves maintain this state until the bottle body 1 rebounds to the initial state.

[0046] In the above structure, the end of the bottle cap 2 away from the bottle body 1 is provided with a sealing plate 22. A circular blind hole 221 is defined in the center of the sealing plate 22. A bushing 221 is connected to the inner wall of the circular blind hole 221. The bushing 221 is located inside the bottle cap 2. A second through-hole 223 is defined at the bottom of the bushing 221. The duckbill valve 5 is connected to the second through-hole 223. A transfer tube 224 is provided on the end surface of the bushing 221 opposite the bottle body 1. One end of the liquid outlet pipe 3 is sleeved onto the outer wall of the transfer tube 224, and the liquid outlet pipe 3 is connected to the duckbill valve 5 through the transfer tube 224. The outer wall of the liquid outlet pipe 3 away from the bushing 221 is provided with a tapered surface 225. The tapered surface 225 causes the wall thickness of the transfer tube 224 to gradually decrease as it approaches the liquid outlet pipe 3. The tapered surface 225 serves as a guide when the liquid outlet pipe 3 is sleeved, facilitating the sleeved installation of the liquid outlet pipe 3 onto the transfer tube 224.

[0047] In the above structure, the end surface of the sealing plate 22 opposite the silicone head 6 is provided with a plurality of arc-shaped protrusions 226, and airflow grooves 227 are formed between the arc-shaped protrusions 226. The air passage 21 penetrates the sealing plate 22 and is connected to the inner cavity of the bottle body 1 through the air passage 21. To ensure the speed at which the bottle body 1 rebounds to its initial state, multiple airflow grooves 227 are additionally provided around the top of the bottle cap 2, thereby increasing the gas flow rate per unit time.

[0048] In the above structure, when the duckbill valve 5 rotates relative to the bottle cap 2 , the cross-sectional area between the duckbill valve 5 and the second through hole 223 changes relatively to achieve a change in the liquid output of the duckbill valve 5 .

[0049] Reference Figure 13 、 14 As shown, the inner wall of the bottle cap 2 is provided with an arched protrusion 23, the gas passage 21 is provided on the arched protrusion 23, and the end of the arched protrusion 23 opposite to the bottle body 1 is provided with an arcuate groove 231, and the one-way valve 4 is provided in the arcuate groove 231. The gas passage 21 is located within the range surrounded by the arcuate groove 231.

[0050] Reference Figure 15 、 16 As shown, the one-way valve 4 includes a mounting portion 41 and a valve disc 42. The mounting portion 41 is arranged in a "C" shape. The valve disc 42 is mounted on the inner wall of the C-shaped groove of the mounting portion 41 and covers the opening at one end of the gas channel 21. The valve disc 42 is a circular thin sheet that can bend under the action of airflow.

[0051] Reference Figure 7 As shown, the duckbill valve 5 includes a connecting block 51 and two symmetrically arranged duckbill valve discs 52. The two symmetrically arranged duckbill valve discs 52 are connected to the connecting block 51. The connecting block 51 is fixedly mounted on the inner wall of the silicone head 6. When the two symmetrically arranged duckbill valve discs 52 are opened, a liquid output opening is formed. The connecting block 51 is provided with a second liquid outlet hole 53. When the duckbill valve 5 is rotated relative to the bottle cap 2, the cross-sectional area of ​​the communication between the second liquid outlet hole 53 and the second through hole 223 changes. An indicator mark 62 is provided on the outer wall of the silicone head 6. Several flow marks 24 are provided on the outer wall of the bottle cap 2 near the silicone head 6. When the indicator mark 62 is aligned with one of the several flow marks 24, it is used to indicate that the flow rate of the nasal wash device at that time is the flow rate. Preferably, three flow cross sections are set, and three different graphics can be used to represent the flow rates of 8mm2, 12mm2 and 16mm2 respectively. The adjustable flow rate design can be adjusted to the appropriate flow rate according to the usage habits of different people.

[0052] After the pressure on the bottle body 1 is released, the two symmetrically arranged duckbill valve pieces 52 are pressed and closed by the external air pressure, which can effectively prevent the liquid from flowing back and prevent the duckbill valve pieces 52 from discharging the liquid.

[0053] Reference Figure 4 、 5 As shown, the number of the liquid outlet holes 61 is set to one or more, that is, the silicone head 6 will have a single hole (such as Figure 4 as shown) or porous (as Figure 5 As shown), the number of porous holes of the silicone head 6 is set to 2 to 6 holes for the best, and the angle between the center line of the opening and the central axis of the silicone head 6 is between 20 and 60 degrees.

[0054] In the above structure, the outer wall of the bottle body 1 is provided with a groove 11 for finger pressure. The concave shape of the groove 11 mimics the shape of a human finger, providing a pleasant tactile sensation when pressed and more ergonomically designed. Side planes are provided on both sides of the bottle body to achieve a stable flow rate output. The outer wall of the bottle mouth of the bottle body 1 is provided with an external thread, and the inner wall of the bottle cap 2 is provided with an internal thread. The bottle mouth of the bottle body 1 and the bottle cap 2 are connected by a threaded connection.

[0055] In order to achieve a good sealing effect between the bottle mouth of the bottle body 1 and the bottle cap 2, an annular protrusion 25 is provided on the inner wall of the bottle cap 2, and an annular gap 26 is provided between the annular protrusion 25 and the inner wall of the bottle cap 2. The bottle mouth of the bottle body 1 is located in the annular gap 26. After the bottle cap 2 is screwed onto the bottle body 1, the inner wall of the bottle mouth of the bottle body 1 and the outer wall of the annular protrusion 25 are interference fit, thereby achieving a sealing effect.

[0056] A scale 12 is provided on the outer wall of the bottle body 1, and the scale 12 is used to indicate the remaining amount of the liquid medicine in the bottle body 1. At the same time, the product logo and instructions are set on the front and back of the bottle body 1 respectively.

[0057] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
