[0030] In order to make the above-mentioned features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0031] Reference Figure 1-6 The present application provides an atomizing nasal mask, comprising:

[0032] The nasal mask body 100 is a hollow structure, and a negative pressure cavity is formed inside the nasal mask body 100. A suction port 103 is provided at the part where the nasal mask body 100 contacts the face. The nasal mask body 100 is also provided with a breathing port 101 and an atomization port 102.

[0033] A pressure regulating assembly 200, the pressure regulating assembly 200 comprising a pressure regulating tube 201 and a piston 202 slidably mounted in the pressure regulating tube 201, the pressure regulating tube 201 being connected to the negative pressure chamber, and the negative pressure in the negative pressure chamber being adjusted by adjusting the position of the piston 202 in the pressure regulating tube 201; and

[0034] A fixing belt 300 is connected to the nasal mask body 100 to enable the nasal mask body 100 to be worn on the bridge of the nose.

[0035] Specifically, the nasal mask body 100 is configured into a mask structure according to the shape of the nose bridge, which can cover the user's nose without covering the patient's mouth. Therefore, when used by an infant, the mask can avoid the infant's mouth, and can be soothed by a pacifier or feeding when the infant is emotionally unstable and uncooperative. In addition, in the present application, the negative pressure in the negative pressure chamber can be adjusted by the pressure regulating component 200, wherein the suction port 103 is connected to the negative pressure chamber and the suction port is in contact with the face and is closed by the facial skin. In some cases, in order to improve the stability and sealing of the fit between the nasal mask body 100 and the face, it can be achieved by increasing the negative pressure in the negative pressure chamber to avoid the separation of the nasal mask body 100 from the face and the escape of drug mist. It can be understood that the setting of the breathing port 101 can facilitate the user to breathe. It is set on the nasal mask body 100, and its edge is sealed and isolated from the negative pressure cavity in the nasal mask body 100; the atomization interface 102 is used to connect an external atomization device. It is set on the nasal mask body 100, and its edge is also sealed and isolated from the negative pressure cavity in the nasal mask body 100.

[0036] Reference Figure 3 It can be understood that the nasal mask body 100 is a double-layer structure, and a support body is arranged inside the double-layer structure.

[0037] Specifically, a negative pressure cavity is formed inside the double-layer structure, and the support body is arranged in the negative pressure cavity to provide a stable support for the double-layer structure, thereby preventing the cavity from collapsing when the negative pressure in the negative pressure cavity is too high. The arrangement of the support body needs to ensure the overall connectivity between the negative pressure cavity and the pressure regulating tube 201, and the support body can be a hard plastic or metal material with perforations.

[0038] Reference Figure 4-6 It can be understood that the piston member 202 includes a piston 2021 and a piston rod 203 connected to the piston 2021, and a rod head member 2023 is provided at one end of the piston rod 203 away from the piston 2021.

[0039] Specifically, the piston member 202 is slidably disposed in the pressure regulating tube 201, and the negative pressure in the negative pressure chamber is adjusted by adjusting the position of the piston 2021 in the pressure regulating tube 201. The rod head member 2023 can be a ball head member or a pull ring member, and the arrangement of the rod head member 2023 facilitates pulling the piston member 202.

[0040] Reference Figure 5 and 6 It can be understood that the pressure regulating assembly 200 further includes a positioning rod 203, and the positioning rod 203 is arranged on the pressure regulating tube 201;

[0041] The piston rod 203 is provided with a plurality of adjustment holes 2024 , and the positioning rod 203 can pass through the pressure regulating tube 201 and be inserted into the adjustment holes 2024 .

[0042] Specifically, the pressure regulating tube 201 is provided with a positioning hole 2011, the positioning rod 203 is inserted into the positioning hole 2011, a retaining ring 2031 is provided at one end of the positioning rod 203 located in the pressure regulating tube 201, and a retaining head 2032 is provided at the other end of the positioning rod 203 located outside the pressure regulating tube 201. The retaining ring 2031 and the retaining head 2032 can prevent the positioning rod 203 from falling off. The piston rod 203 is provided with a plurality of adjustment holes 2024 along its length direction, and when the positioning rod 203 is inserted into different adjustment holes 2024, different negative pressures in the negative pressure chamber can be adjusted. For example Figure 6 When the adjusting rod is inserted into the adjusting hole 2024 far from the piston 2021, the negative pressure in the negative pressure chamber is relatively small; when the adjusting rod is inserted into the adjusting hole 2024 close to the piston 2021, the negative pressure in the negative pressure chamber is relatively large. Thus, by adjusting the different negative pressures in the negative pressure chamber, the different fits of the entire nasal mask body 100 can be adjusted, so that it can be suitable for different users.

[0043] Reference Figure 6 It can be understood that a return spring 204 is provided between the positioning rod 203 and the voltage regulating tube 201 .

[0044] Specifically, the setting of the return spring 204 enables the positioning rod 203 to be stably inserted into the adjustment hole 2024, avoiding the movement of the piston 202 due to the detachment of the positioning rod 203, thereby changing the negative pressure in the negative pressure chamber, and further changing the fit and sealing of the nasal mask body 100.

[0045] It is understandable that a one-way valve may be provided on the breathing port 101 , and a one-way valve may be provided on the atomization port 102 .

[0046] Specifically, the one-way valve on the breathing port 101 is in a closed state during inhalation and in an open state during exhalation; meanwhile, the one-way valve on the atomization interface 102 is in an open state during inhalation and in a closed state during exhalation. By providing two one-way valves, the sealing inside the nasal mask body 100 can be better ensured, and the drug mist can be prevented from escaping, causing the problem of drug solution waste and insufficient drug administration.

[0047] Reference Figure 3 It can be understood that a flexible pad 104 is arranged around the suction port 103 .

[0048] Specifically, the flexible pad 104 is arranged at the periphery of the edge of the suction port 103 to fill the contact position between the baby's cheek and the edge of the nasal mask body 100, which can improve comfort on the one hand and improve sealing on the other hand.

[0049] Reference Figure 1 and 2 It can be understood that there is at least one fixing belt 300.

[0050] Specifically, in the embodiment of the present application, there are two fixing straps 300, which are respectively connected to the upper part and the lower part of the nose mask body 100, so as to improve the wearing stability of the nose body.

[0051] It is understandable that the nasal mask body 100 is made of transparent material.

[0052] It is understandable that the fixing belt 300 is made of elastic material.

[0053] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the principles of the present application shall be included in the protection scope of the present application.
