Furthermore, the terms "first" and "second" are used only for descriptive purposes and are not intended to have a special meaning.

The specific structure of the nasal irrigator according to the embodiment of the present invention will be described with reference to fig. 1 to 6.

As shown in figures 1-4, the nose washer of the embodiment of the utility model comprises a cup body 1, a liquid medicine injection device and a cup cover 4. The cup body 1 is provided with a liquid medicine cavity 11, and the liquid medicine cavity 11 is used for containing liquid medicine. The liquid medicine injection device is arranged on the bottom wall 12 of the cup body 1 in a penetrating way, a spray hole 32 is arranged on the liquid medicine injection device, the liquid medicine injection device is communicated with the liquid medicine cavity 11 and is configured to spray the liquid medicine in the liquid medicine cavity 11 out of the spray hole 32. One side of the cup cover 4 is provided with a liquid nozzle 41, the other side of the cup cover 4 is provided with a mist nozzle 42, and the cup cover 4 is provided with a first matching position and a second matching position. In the first fitting position, the liquid ejection nozzle 41 faces the ejection orifice 32; in the second, engaged position, the mist nozzle 42 is facing the spray orifice 32.

It can be understood that when the cup cover 4 is located at the first matching position, the liquid medicine spraying device sprays the liquid medicine in the liquid medicine cavity 11 from the spraying hole 32, the liquid medicine sprayed from the spraying hole 32 enters the liquid nozzle 41, the liquid medicine passes through the liquid nozzle 41 and then enters the nasal cavity from one side of the nasal cavity to clean the inner part of the nasal cavity, and then the other side of the nasal cavity or the pharyngeal portion flows out, and meanwhile, the secretion in the nasal cavity is brought out, so that the purpose of cleaning the nasal cavity is achieved.

When the cup cover 4 is located at the second matching position, the liquid medicine spraying device sprays the liquid medicine in the liquid medicine cavity 11 from the spray hole 32, the liquid medicine sprayed from the spray hole 32 enters the mist nozzle 42, and atomized liquid medicine is formed under the action of the mist nozzle 42. The grain diameter of the liquid medicine particles of the atomized liquid medicine can be adjusted by adjusting the relevant parameters of the liquid medicine injection device, so that the atomized liquid medicine has smaller grain diameter of the liquid medicine particles and can directly treat the target organ. Because the atomized liquid medicine can be directly absorbed by the target organ, the liquid medicine lost in the administration process does not need to be considered in the actual use process, thereby not only accelerating the recovery of the target organ and improving the treatment effect, but also reducing the administration amount and lowering the treatment cost.

In addition, the specific implementation manner of switching between the first fitting position and the second fitting position of the cup cover 4 is not limited as long as the nozzle communicated with the liquid medicine circulating piece can be switched. In this embodiment, the liquid nozzle 41 and the mist nozzle 42 are symmetrically arranged on the cup lid 4, the cup lid 4 is detached, and the cup lid is rotated by 180 degrees and then mounted on the cup body 1, so that the matching position can be switched. Of course, the liquid nozzle 41 and the mist nozzle 42 may also be asymmetrically arranged on the cup cover 4, and the cup cover 4 is detached and then installed on the cup body 1 by rotating by a corresponding angle, so that the matching position can be switched.

To sum up, the embodiment of the utility model provides a can spout liquid medicine and vaporific liquid medicine, therefore has wider treatment scope, can accomplish the nasal cavity and wash, can atomize the liquid medicine again, has reached the purpose of dual-purpose, the high-efficient treatment of an object.

In some embodiments, as shown in fig. 1 to 4, the liquid medicine ejection device includes a gas flow member 2 and a liquid medicine flow member 3. The gas circulation piece 2 is arranged on the bottom wall 12 of the cup body 1 in a penetrating mode, the gas circulation piece 2 is provided with a gas circulation cavity 21, the gas circulation cavity 21 is communicated with the liquid medicine cavity 11, and the gas circulation cavity 21 can be communicated with the high-speed airflow generator. The liquid medicine circulation piece 3 is sleeved on the gas circulation piece 2, a liquid medicine channel 31 is formed between the inner peripheral wall of the liquid medicine circulation piece 3 and the gas circulation piece 2, one end of the liquid medicine circulation piece 3 facing the bottom wall 12 and the bottom wall 12 are arranged at intervals and are arranged in an open mode, and a spray hole 32 is formed in one end, far away from the cup bottom wall 12, of the liquid medicine circulation piece 3.

It can be understood that when the cup cover 4 is located at the first matching position, the high-speed airflow provided by the high-speed airflow generator enters the air circulation chamber 21 through the conduit for circulation, and generates a negative pressure effect on the liquid medicine passage 31 at the communication position of the air circulation chamber 21 and the liquid medicine passage 31, so as to suck the liquid medicine in the liquid medicine chamber 11 to the liquid medicine passage 31 and eject the liquid medicine from the ejection hole 32. After that, under the action of the high-speed airflow, the liquid medicine sprayed from the spray hole 32 passes through the liquid nozzle 41 and enters the nasal cavity from one side of the nasal cavity to clean the interior of the nasal cavity, and then flows out from the other side of the nasal cavity or the pharyngeal portion, and meanwhile, the secretion in the nasal cavity is taken out, so that the purpose of cleaning the nasal cavity is achieved.

When the cup cover 4 is located at the second matching position, the high-speed airflow provided by the high-speed airflow generator enters the gas circulation cavity 21 through the conduit for circulation, and generates a negative pressure effect on the liquid medicine channel 31 at the communication position of the gas circulation cavity 21 and the liquid medicine channel 31, so that the liquid medicine in the liquid medicine cavity 11 is sucked to the liquid medicine channel 31. The chemical liquid ejected from the nozzle hole 32 enters the mist nozzle 42, and is formed into an atomized chemical liquid by the mist nozzle 42. The particle diameter of the liquid medicine particles under the action of the high-speed airflow can be adjusted by adjusting the aperture of the spray hole 32 of the liquid medicine circulating piece 3 and the pressure and the flow rate of the high-speed airflow, so that the atomized liquid medicine can directly treat a target organ. Because the atomized liquid medicine can be directly absorbed by the target organ, the liquid medicine lost in the administration process does not need to be considered in the actual use process, thereby not only accelerating the recovery of the target organ and improving the treatment effect, but also reducing the administration amount and lowering the treatment cost.

It should be added that, besides the above structure, the liquid medicine can be formed into liquid form and atomized form, and the cup body can be provided with a vibration piece and a pump body at the same time. When the cup cover 4 is positioned at the first matching position, the liquid medicine is sprayed out under the action of the pump body to form liquid medicine and wash the nasal cavity. When the cup cover 4 is positioned at the second matching position, the liquid medicine is atomized under the action of the oscillating piece and forms atomized liquid medicine to treat the target organ.

In some embodiments, as shown in fig. 2, 3 and 6, the mist nozzle 42 is provided with an atomizing member 422, the atomizing member 422 is provided with an air flow through hole 4221, the atomizing member 422 is provided with a projection 4222, and when the cap 4 is located at the second matching position, the projection 4222 is directly opposite to the spray hole 32 of the liquid medicine circulating member 3.

It can be understood that, although the particle diameter of the liquid medicine particles of the atomized liquid medicine can be adjusted by adjusting the aperture of the nozzle hole 32 of the liquid medicine circulating member 3 and the pressure and flow rate of the high-speed air flow, the above adjusting manner is cumbersome and the effect is difficult to be expected, so the structure of the atomizing member 422 is optimized to reduce the particle diameter of the liquid medicine particles of the atomized liquid medicine, enhance the atomizing effect of the atomized liquid medicine, make the atomized liquid medicine be absorbed by the lower respiratory tract and the lung of the human body more easily, and further improve the therapeutic effect of the liquid medicine.

Specifically, the atomizing member 422 is provided with an airflow through hole 4221 and a projection 4222, and when the cup lid 4 is located at the second matching position, the projection 4222 is arranged to face the spray hole 32 of the liquid medicine circulating member 3. The liquid medicine passes through the spray holes 32 of the liquid medicine circulating piece 3 under the action of Venturi effect and impacts the bumps 4222 under the action of high-speed air flow, and is dispersed after impact to form atomized liquid medicine with smaller liquid medicine particle size, and then enters the fog nozzle 42 through the air circulation holes 4221. The atomized liquid medicine acted by the atomization piece 422 has smaller liquid medicine particle size and is not easy to collide and combine, so that the requirements of more treatment conditions can be met, the waste of the liquid medicine is reduced, the utilization rate of the liquid medicine is improved, and a better treatment effect is achieved on a target organ.

In some embodiments, as shown in fig. 2, 3, 5, the nasal irrigator further comprises a support wall 5 and a closure 6. The support wall 5 is connected to the bottom wall 12 of the cup body 1, and the gas flow member 2 is provided with a gas hole 22 below the bottom wall 12 of the cup body 1. The closing member 6 is arranged through the supporting wall 5 and corresponding to the air hole 22. The closure 6 has an initial position, in which the closure 6 releases the air hole 22, and a locking position; in the locked position, the closure 6 closes the air hole 22.

It will be appreciated that in the use of the nasal irrigator, high velocity gas flow is generally required through a relatively long conduit into the gas flow member 2, the high velocity gas flow generator being generally located at a distance from the user. In this case, it is difficult for the user to simultaneously operate the high-speed airflow generator during use of the nasal irrigator. In addition, even if the nasal irrigator and the high-speed airflow generator can be operated simultaneously, the service life of the high-speed airflow generator is easily shortened by frequently opening and closing or plugging and unplugging the high-speed airflow generator. Therefore, a structure which can enable a user to conveniently and quickly adjust high-speed airflow needs to be arranged on the nose washer.

Specifically, the gas flow member 2 is provided with a gas hole 22 below the bottom wall 12 of the cup body 1, the bottom wall 12 of the cup body 1 is connected with the supporting wall 5, the supporting wall 5 is provided with a sealing member 6 in a penetrating way, and the sealing member 6 can release or seal the gas hole 22. When the closing piece 6 closes the air hole 22, the high-speed air flow can only enter the liquid medicine cavity 11 through the air circulating piece 2, and the liquid medicine in the liquid medicine cavity 11 is driven to circulate through the liquid medicine channel 31 and enter the liquid nozzle 41 or the mist nozzle 42 under the action of the venturi effect. When the closing piece 6 releases the air hole 22, the high-speed airflow is directly dissipated to the outside through the air hole 22, and the liquid medicine in the liquid medicine cavity 11 cannot pass through the liquid medicine channel 31 under the action of negative pressure generated by the high-speed airflow, so that the function of nasal cavity flushing or liquid medicine atomization is stopped. By using the structure, the fast switching between the work and the pause of the high-speed airflow can be realized, the service life of the nose washer is prolonged, and the use experience of a user is improved. In addition, because the high-speed airflow can be quickly suspended under the action of the structure, the spraying of the liquid medicine can also be quickly suspended, the liquid medicine can be saved, and the treatment cost is reduced.

In some embodiments, the cross-sectional area of the gas holes 22 is larger than the cross-sectional area of the connection between the gas flow-through member 2 and the drug solution chamber 11. It can be understood that when the cross-sectional area of the air hole 22 is larger than the cross-sectional area of the communication part of the air circulation piece 2 and the liquid medicine cavity 11, the high-speed air flow is completely dissipated from the air hole 22 and does not enter the liquid medicine cavity 11 to drive the liquid medicine to enter the liquid medicine channel 31, so that the function of completely stopping nasal cavity flushing or liquid medicine atomization can be achieved, the service life of the nasal irrigator is further prolonged, the liquid medicine is saved, and the treatment cost is reduced.

In some embodiments, as shown in fig. 5, the closing member 6 is provided with a hook 61, and the supporting wall 5 is provided with a latch 51 engaged with the hook 61.

It will be appreciated that in order to avoid the closure member 6 falling out of the support wall 5 and failing to perform the function of closing the air aperture 22, the closure member 6 is required to be movable only inside the support wall 5. Through setting up pothook 61 on closure 6, set up the fixture block 51 with pothook 61 cooperation in supporting wall 5, when closure 6 will deviate from supporting wall 5, the cooperation between pothook 61 and the fixture block 51 makes closure 6 can't continue to move to supporting wall 5 outside to make better closure of closure 6 or release air vent 22, improved user's use experience.

In some embodiments, as shown in fig. 2 and 3, the cup body 1 is provided with a guide groove 13, and the closing member 6 is provided with a guide projection 62 fitted in the guide groove 13. It will be understood that there is a travel between the initial position of the closure 6 and the closed position, when the closure 6 is in the closed position, it is possible for the closure 6 to tip towards the inside of the supporting wall 5. For this purpose, a guide groove 13 is provided in the cup body 1, and a guide projection 62 fitted in the guide groove 13 is provided in the closure 6. When the closing piece 6 is pressed, the guide projection 62 slides along the guide groove 13, so that the closing piece 6 can only slide in the length direction of the guide groove 13, and the closing piece 6 can better close or release the air hole 22, and the use experience of a user is improved.

In some embodiments, as shown in fig. 1-5, the lid 4 further includes a lid wall 43, the lid wall 43 is disposed upward along the circumferential surface of the lid 4, a partition 44 is disposed between the mist nozzle 42 and the liquid nozzle 41, and the partition 44 and the lid wall 43 on the side of the liquid nozzle 41 form a gutter 45. It can be understood that when the cup cover 4 is located at the first matching position, the high-speed air flow drives the liquid medicine to be sprayed out from the liquid nozzle 41, so that the nasal irrigator can clean the nasal cavity. In the process of cleaning the nasal cavity, the cleaned liquid medicine is discharged from the nostrils or the pharynx, and the liquid waste discharged from the pharynx can cause discomfort, so the liquid waste is generally discharged from the nostrils. Therefore, the cup cover wall 43 is arranged on the cup cover 4, the partition plate 44 is arranged between the mist nozzle 42 and the liquid nozzle 41, the partition plate 44 and the cup cover wall 43 on the side of the liquid nozzle 41 form a sewage groove 45, waste liquid discharged from nostrils can directly enter the sewage groove 45, the possibility of contact between the waste liquid and a human body is avoided, and the use experience of a user is improved.

In some embodiments, as shown in fig. 2 and 3, the cup cover 4 is provided with a nozzle cover 7, and the nozzle cover 7 is matched with the cup cover 4 and seals the mist nozzle 42 and the liquid nozzle 41; the mist nozzle cover 8 is arranged on the mist nozzle 42, and the mist nozzle cover 8 can seal the mist nozzle 42. It can be understood that, in the use process of the nasal irrigator provided by the embodiment of the present invention, the liquid medicine will directly contact with the easily contaminated mist nozzle 42 and liquid nozzle 41, so that the cleanness of the mist nozzle 42 and the liquid nozzle 41 needs to be ensured. In addition to the integrated disinfection and sterilization of the nasal irrigator, it is also necessary to provide a nozzle cover 7 for the mist nozzle 42 and the liquid nozzle 41 to be closed and protected. The nozzle cover 7 can prevent foreign matters such as dust from polluting the mist nozzle 42 and the liquid nozzle 42 in the preservation process after the nasal irrigator is used, thereby playing a good role in protecting the nasal irrigator and improving the safety of the nasal irrigator in the use process.

Use the utility model discloses the in-process that the nose syringe provided with the embodiment atomizes the liquid medicine and inhales the target organ, and the atomizing liquid medicine probably brings the bacterium that appears in the use into the target organ to cause unnecessary infection, for example the pollution of liquid medicine, the pollution of high velocity air or the pollution of nose syringe etc. to the target organ. In order to avoid the above phenomenon, in addition to performing disinfection and sterilization treatment on the whole nasal irrigator, a mist nozzle cover 8 capable of sealing the nozzle opening of the mist nozzle 42 is also required to be arranged at the nozzle opening for protection. In the process of cleaning the nasal cavity by using the liquid nozzle 41, the mist nozzle cover 8 is used for sealing the mist nozzle 42, so that the used waste liquid cannot cause secondary pollution to the mist nozzle 42; in the treatment of the target organ using the mist nozzle 42, the mist nozzle cover 8 is opened. In the sealing process of the nose washer, the mist nozzle cover 8 can also play a better protection role on the mist nozzle 42, so that the safety of the mist nozzle 42 in the using process is improved, and the secondary infection of the nose washer to target organs in the using process is avoided.

In some embodiments, the outer wall of the cup body 1 is provided with graduation marks to display the volume of the liquid medicine at different graduation marks. It is understood that, in actual use, the user has a quantitative requirement for the amount of liquid medicine required for cleaning the nasal cavity or the amount of atomized liquid medicine absorbed. The steps of preparing a fixed amount of liquid medicine in advance and pouring the liquid medicine into the liquid medicine cavity 11 are complicated and have certain errors, and when the amount of liquid medicine in the liquid medicine cavity 11 is small, the situation that the residual liquid medicine cannot rise and be atomized under the action of high-speed airflow may occur, and the fixed amount of liquid medicine is difficult to use. Therefore, a plurality of scale marks are arranged on the outer wall of the cup body 1 to display the volumes of the liquid medicines on different scale marks. At the moment, the aim of finishing the treatment process by quantitatively using the liquid medicine can be fulfilled by confirming the volume difference between the liquid medicine before use and the liquid medicine after use, and the method is simple, convenient and easy to operate.
