[0029] The utility model provides a kind of spray suction nose device 100.

[0030] Please refer to Figures 1 to 3In an embodiment of the present utility model, the spray suction nose device 100 includes a shell 1, a spraying part 2, and a suction part 3. The shell 1 has an installation cavity 1a formed inside. The spraying part 2 includes an atomization assembly 21 and a liquid storage tank 22. Both the atomization assembly 21 and the liquid storage tank 22 are arranged in the installation cavity 1a. The liquid storage tank 22 is used to provide liquid for the atomization assembly 21, so that the liquid can be atomized and sprayed out. The suction part 3 includes an air pump 31, a suction assembly 32, and a noise reduction assembly 33. The air pump 31, the suction assembly 32, and the noise reduction assembly 33 are all arranged in the installation cavity 1a. The air pump 31 has an exhaust pipe 311 and an air suction pipe 312. The noise reduction assembly 33 includes an air path adapter 331 and a sealing member 332. The air path adapter 331 is detachably connected with the sealing member 332. The air path adapter 331 and the sealing member 332 enclose a noise reduction channel 33a. The cross-sectional area of the noise reduction channel 33a in the airflow discharge direction is larger than that of the exhaust pipe 311. The noise reduction channel 33a is connected with the exhaust pipe 311 and the outside, so as to buffer the airflow discharged from the exhaust pipe 311.

[0031] In this embodiment, the shell 1 has an installation cavity 1a formed inside, which is used to accommodate various components such as the spraying part 2 and the suction part 3. The spraying part 2 is composed of an atomization assembly 21 and a liquid storage tank 22. Both components are installed in the installation cavity 1a. The liquid storage tank 22 is responsible for storing the liquid used for atomization, while the atomization assembly 21 is connected to the liquid storage tank 22. By pressing or using electronic components, the liquid in the liquid storage tank 22 can be converted into an atomized form and sprayed out, achieving the delivery or cleaning of the nasal cavity. The liquid in the liquid storage tank 22 can be water or medicine for treatment. This design makes the spray suction nose device 100 more compact, convenient to carry and use. Integrating the atomization assembly 21 and the liquid storage tank 22 in the installation cavity 1a of the shell 1 can reduce external connections of the device, lower the risk of leakage, and simplify the manufacturing and assembly process. In addition, the compact design also helps to improve the stability and durability of the device, as all components are protected by the shell 1. The direct connection between the liquid storage tank 22 and the atomization assembly 21 ensures the continuity and efficiency of the atomization process, so that the liquid can be quickly and uniformly atomized and sprayed out, improving the use effect and user experience of the spray suction nose device 100.

[0032] In an embodiment, the suction part 3 integrates the air pump 31, the suction assembly 32 and the noise reduction assembly 33, which are all installed in the mounting cavity 1a in the housing 1. The air pump 31 is designed with an exhaust pipe 311 and an air inlet pipe 312 for controlling the inflow and outflow of air. The noise reduction assembly 33 is composed of an air path adapter 331 and a sealing member 332, which are connected in a detachable manner by bolts or buckles, facilitating maintenance and replacement. The air path adapter 331 and the sealing member 332 together enclose a noise reduction channel 33a, which has a larger cross-sectional area than the exhaust pipe 311 to ensure that the air flow is effectively buffered when it is discharged. The noise reduction channel 33a is directly connected to the exhaust pipe 311 and the external environment, so that the air flow discharged by the air pump 31 slows down when passing through the noise reduction channel 33a, thereby reducing noise. This design significantly reduces the noise generated by the air pump 31 when it is working, improves the comfort of use, and is especially suitable for environments or people sensitive to noise, such as infants and young children. By increasing the cross-sectional area of the noise reduction channel 33a, the turbulent flow and vortex flow of the air flow when it is discharged are effectively reduced, which are usually the main sources of noise. In addition, the detachable design of the air path adapter 331 and the sealing member 332 makes it easier to maintain and clean the device, prolonging the service life of the product. Overall, this technical solution achieves multiple advantages of reducing noise, improving user experience and maintenance convenience through simple structural improvements.

[0033] The technical scheme of the utility model designs a kind of spray suction nose device 100, which integrates a noise reduction assembly 33 in the suction part 3, and the noise reduction assembly 33 is composed of an air path adapter 331 and a sealing member 332, which are connected in a detachable manner by buckles or bolts and enclose a noise reduction channel 33a. The cross-sectional area of the noise reduction channel 33a is larger than that of the exhaust pipe 311, and it is directly connected to the exhaust pipe 311 and the external environment, effectively buffering the air flow discharged by the air pump 31, thereby reducing the noise generated when the air flow is directly discharged. Since the cross-sectional area of the noise reduction channel 33a is larger than that of the exhaust pipe 311, the air flow slows down when it is discharged through the noise reduction channel 33a. According to the principles of fluid mechanics, the reduction of air flow speed can reduce the formation of turbulent flow and vortex flow, which are the main factors of noise. The slowed air flow reduces the impact on the surrounding environment, thereby reducing the noise level. In addition, the detachable design of the air path adapter 331 and the sealing member 332 also facilitates maintenance and replacement, further improving the practicality and service life of the device. Therefore, this technical solution can effectively reduce the noise generated by the spray suction nose device 100 when it is working, improve the user experience, and improve the spray suction effect, especially suitable for user groups sensitive to noise, such as infants and young children.

[0034] In an embodiment of the utility model, please refer to Figure 4The air path adapter 331 is provided with a noise reduction inlet 331b and a noise reduction outlet 33b which are arranged at intervals, the noise reduction inlet 331b is communicated with the exhaust pipe 311 and the noise reduction channel 33a, and the noise reduction outlet 33b is communicated with the noise reduction channel 33a and the outside.

[0035] In an embodiment, the key to the noise reduction of the noise reduction assembly 33 lies in the structural design of the air path adapter 331. The air path adapter 331 is specially provided with the noise reduction inlet 331b and the noise reduction outlet 33b, which are arranged at intervals, so as to ensure that the airflow can effectively utilize the space in the noise reduction channel 33a when passing through the noise reduction channel 33a, thereby achieving the effect of reducing noise. The noise reduction inlet 331b is directly communicated with the exhaust pipe 311 and the noise reduction channel 33a, so that the airflow discharged by the air pump 31 first enters the noise reduction channel 33a; and the noise reduction outlet 33b is communicated with the noise reduction channel 33a and the outside, allowing the buffered airflow to be discharged to the external environment. Such a design makes the airflow effectively decelerate and disperse during discharge, reducing the noise generated when the airflow is directly discharged. Through the interval arrangement of the noise reduction inlet 331b and the noise reduction outlet 33b on the air path adapter 331, the utility model can effectively reduce the airflow noise generated when the air pump 31 works. This design not only reduces the turbulence and vortex of the airflow during discharge, reduces the noise, but also avoids the impact on the surrounding environment, so that the spray suction nose device 100 is more quiet during operation. In addition, since the cross-sectional area of the noise reduction channel 33a is larger than that of the exhaust pipe 311, the speed of the airflow is slowed down when passing through the noise reduction channel 33a for discharge, further reducing the noise level and improving the user experience.

[0036] In an embodiment of the utility model, please refer to Figure 4 The air path adapter 331 is provided with at least two blocking pieces 3311, and each blocking piece 3311 is located at the circumference of the noise reduction outlet 33b.

[0037] In the embodiment, the air path adapter 331 is provided with at least two blocking pieces 3311 which are uniformly distributed around the periphery of the noise reduction outlet 33b. The air flow of the exhaust pipe 311 flows along the path shown by the dashed line in the figure, and the blocking pieces 3311 can block the plate or boss between the noise reduction inlet 331b and the noise reduction outlet 33b. The blocking pieces 3311 can guide the air flow along a specific path, so that the air flow is dispersed when passing through the noise reduction outlet 33b, thereby reducing the air flow speed and noise. At the same time, the blocking pieces 3311 can prevent foreign matters from entering the noise reduction channel 33a through the noise reduction outlet 33b. Such a design can make the air flow more stable when being discharged, reduce the noise generated when the air flow is directly discharged, and the presence of the blocking pieces 3311 can also help to reduce the impact of the air flow on the surrounding components and reduce the vibration noise. By providing the blocking pieces 3311 on the air path adapter 331, the air flow noise generated by the air pump 31 during operation can be effectively reduced. Such a design not only reduces the turbulence and vortex of the air flow when being discharged, thereby reducing the noise, but also avoids the impact on the surrounding environment, so that the spray suction nose device 100 is more quiet during operation. In addition, the provision of the blocking pieces 3311 can also help to improve the stability of the air flow and reduce the impact of the air flow on other components inside the device, thereby reducing the additional noise generated by vibration. Therefore, the technical scheme not only reduces the noise, but also improves the use comfort and stability of the device.

[0038] In one embodiment of the utility model, please refer to Figure 1 The air path adapter 331 and the sealing piece 332 are made of EVA material or silica gel material.

[0039] In one embodiment, the air path adapter 331 and the sealing piece 332 are made of EVA material or silica gel material. EVA material, i.e. ethylene-vinyl acetate copolymer, has good low-temperature resistance, flexibility and processability. Silica gel material is known for its excellent temperature resistance, corrosion resistance, insulation and physiological inertia, and can maintain good performance in various harsh environments. These two materials are widely used in applications that require shock absorption, sealing performance and temperature stability. EVA material and silica gel material both have certain sound absorption effect, which can reduce the noise generated when the air flow passes through. Both materials have good sealing performance, which can effectively prevent gas leakage and ensure the air tightness of the spray suction nose device 100. The physiological inertia of silica gel material makes it safer and more comfortable when used in medical equipment. Selecting EVA material or silica gel material as the material of the air path adapter 331 and the sealing piece 332 can not only effectively reduce the noise of the spray suction nose device 100 during operation, but also improve the sealing performance and durability of the device, making the equipment safer, more comfortable and easier to maintain.

[0040] In one embodiment of the utility model, please refer toFigures 4 to 6 The noise reduction assembly 33 further comprises a sealing ring 333, the sealing member 332 forms an extension arm 3331, the air path adapter 331 is provided with a sealing portion 3312, and the sealing ring 333 abuts against the extension arm 3331 and the sealing portion 3312 to seal the noise reduction channel 33a.

[0041] In the embodiment, the design of the noise reduction assembly 33 comprises the sealing ring 333, the extension arm 3331 and the sealing portion 3312. The sealing member 332 is designed with the extension arm 3331, and the air path adapter 331 is provided with the sealing portion 3312. The sealing ring 333 is an O-ring or a sealing gasket, and is generally made of rubber or silicone. The sealing ring 333 is arranged to abut against the extension arm 3331 and the sealing portion 3312 to seal the noise reduction channel 33a. Such a design ensures that the air flow is sealed when passing through the noise reduction channel 33a, thereby effectively reducing the air flow noise generated by the air pump 31 during operation. The use of such a sealing structure can improve the air tightness of the spray and suction nose device 100 during operation, reduce gas leakage, and thus reduce noise. The cooperation of the sealing ring 333, the extension arm 3331 and the sealing portion 3312 forms a closed noise reduction channel 33a, so that the air flow is more stable when being discharged, and the noise generated by the direct discharge of the air flow is reduced. In addition, the use of the sealing ring 333 also helps to reduce the vibration caused by the impact of the air flow, further improving the noise reduction effect of the device. This design not only reduces noise, but also improves the stability and service life of the device, making the spray and suction nose device 100 more suitable for use in quiet environments such as hospitals and homes.

[0042] In an embodiment of the utility model, please refer to Figures 1 to 3 The suction assembly 32 comprises a suction nose head 321 and a suction nose bin 322. The suction nose head 321 has a suction nose channel 321a, and the suction nose bin 322 has an air suction channel 322a. The suction nose channel 321a and the air suction channel 322a are arranged in a spaced manner, and the suction nose channel 321a is in communication with the air suction channel 322a and the outside.

[0043] In one embodiment, the suction assembly 32 is composed of two main parts: the suction nose 321 and the suction nose chamber 322. The suction nose 321 is designed with a suction channel 321a, which is used to extend into the nasal cavity and absorb foreign matter such as nasal discharge or sputum. The suction nose chamber 322 is provided with an air suction channel 322a, which is mainly used to connect the air suction pipe 312 of the air pump 31, so that a negative pressure is generated in the suction channel 321a, thereby causing the suction nose 321 to suck in air flow and foreign matter through the suction channel 321a. The suction channel 321a and the air suction channel 322a are spaced apart, i.e., they are structurally separated but functionally connected. The suction channel 321a directly connects the air suction channel 322a with the outside world, ensuring that the foreign matter absorbed from the nasal cavity can be smoothly transmitted to the suction nose chamber 322 without being sucked into the air pump 31, thereby achieving effective suction function. This design enables the suction assembly 32 to effectively suck foreign matter from the nasal cavity while maintaining smooth airflow. By spacing the suction channel 321a and the air suction channel 322a, the resistance of the airflow during the suction process can be reduced, improving the efficiency of the suction. In addition, this design also helps to reduce the noise that may be generated by the device during the suction process, as smooth transmission of airflow can reduce turbulence and vortex flow, which are often the sources of noise. Furthermore, by separating the suction channel 321a and the air suction channel 322a, the direct impact of foreign matter on the airflow channel can also be reduced, thereby reducing noise and vibration caused by foreign matter, improving user comfort and the service life of the device.

[0044] In one embodiment of the present application, please refer to Figure 3 The suction nose chamber 322 has a temporary storage cavity 322b, and the suction channel 321a and the air suction channel 322a both communicate with the temporary storage cavity 322b.

[0045] In this embodiment, the design of the nasal suction bin 322 includes a temporary storage cavity 322b for temporarily storing foreign matter suctioned from the nasal cavity. The nasal suction head 321 is provided with a nasal suction channel 321a, and the nasal suction bin 322 is provided with an air suction channel 322a, both of which communicate with the temporary storage cavity 322b. In actual operation, the nasal suction channel 321a of the nasal suction head 321 first adsorbs foreign matter in the nasal cavity, and then transmits the foreign matter to the temporary storage cavity 322b of the nasal suction bin 322 through the air suction channel 322a, thereby completing the suction process. The main advantage of this design is that it can effectively temporarily store the adsorbed foreign matter in the temporary storage cavity 322b of the nasal suction bin 322, avoiding the direct entry of foreign matter into the air pump 31 or subsequent components, thereby reducing the pollution and damage to the internal components of the device. The presence of the temporary storage cavity 322b makes it easier to collect and clean foreign matter, and also improves the working efficiency and safety of the device. In addition, by connecting the nasal suction channel 321a and the air suction channel 322a to the temporary storage cavity 322b, it can ensure smooth transmission of air flow and foreign matter, reduce backflow or blockage that may occur during the suction process, and thus improve the overall performance and user experience of the nasal suction device 100.

[0046] In one embodiment of the present application, please refer to Figure 2 and Figure 3 The height of the air suction channel 322a along its axial direction is greater than the height of the nasal suction channel 321a.

[0047] In one embodiment, the design of the air suction channel 322a is one of the key features. Specifically, the height of the air suction channel 322a along its axial direction is designed to be greater than the height of the nasal suction channel 321a along its axial direction. This design can prevent foreign matter suctioned from the nasal suction channel 321a from entering the air suction channel 322a. Both the nasal suction channel 321a and the air suction channel 322a communicate with the temporary storage cavity 322b, which allows foreign matter suctioned from the nasal cavity to be smoothly transmitted to the temporary storage cavity 322b of the nasal suction bin 322, improving the suction efficiency and working performance of the device. The larger height difference in the axial direction also helps to improve the stability of the device, so that the foreign matter in the nasal cavity directly enters the temporary storage cavity 322b and is easier to be removed.

[0048] In one embodiment of the present application, please refer to Figure 4 The air path adapter 331 is provided with an air suction adapter port 331a, which communicates the air suction channel 322a and the air suction pipe 312.

[0049] In this embodiment, the air path adapter 331 is designed to open an air suction adapter port 331a, which directly communicates the air suction channel 322a in the suction assembly 32 with the air suction pipe 312 of the air pump 31. Such a design allows the air flow sucked from the nasal cavity to directly pass through the nasal suction channel 321a into the air suction channel 322a, and then smoothly transmit to the air suction pipe 312 of the air pump 31 through the air suction adapter port 331a, thereby realizing effective air flow exchange. By providing the air suction adapter port 331a, the spray and suction nasal device 100 of the present application can ensure that the transmission path of the air flow and foreign matter is minimized, reducing the resistance and noise of the air flow during transmission. This direct communication mode improves the transmission efficiency of the air path, reduces the possibility of air flow turbulence or vortex, thereby reducing noise generation. At the same time, this design also simplifies the air path structure, making the device more compact, facilitating integration and maintenance, and improving the overall performance and reliability of the device.

[0050] In one embodiment of the present application, please refer to Figure 1 and Figure 2 The spray part 2 further comprises a nasal suction cover 23 connected to the housing 1, which communicates the atomization assembly 21 with the outside.

[0051] In one embodiment, the design of the spray part 2 includes a nasal suction cover 23 which is directly connected to the housing 1 by means of buckles or bolts and the like, and is hollow inside, capable of communicating the atomization assembly 21 with the outside environment. This design allows the atomized liquid or drug to be directly delivered to the user's nasal cavity through the nasal suction cover 23, realizing direct delivery from the atomization assembly 21 to the user's nasal cavity. By directly connecting the nasal suction cover 23 to the housing 1 and making it communicate the atomization assembly 21 with the outside, the structure of the device is simplified, making manufacturing and maintenance more convenient. The direct communication design reduces the loss of atomized liquid during transmission, improving the utilization efficiency of the drug. The design of the nasal suction cover 23 allows the user to more conveniently receive spray treatment, enhancing the comfort and compliance of use. Finally, this design also helps to reduce the spread of atomized liquid in the external environment, avoiding unnecessary waste and pollution, making the spray nasal irrigator more environmentally friendly and hygienic.

[0052] The above is only an exemplary embodiment of the present application, and does not limit the patent scope of the present application, any equivalent structural transformation made by using the contents of the present application specification and drawings, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
