[0022] Example: Figures 1 to 5 As shown, the portable air purifier of the present application comprises a breathing mask 10 , a hose 20 , a small air purifier 30 , two upper straps 40 and two lower straps 50 .

[0023] One end of the hose 20 is connected to the air outlet 32 ​​of the small air cleaner 30 , and the other end of the hose 20 is connected to the breathing mask 10 .

[0024] The breathing mask 10 is made of a transparent material, and the hose 20 is made of a transparent silicone.

[0025] It should be noted that the respirator 10 is slightly larger than the tip of the nose. The respirator 10 is worn on the user's nose when in use. The specific size of the respirator 10 is selected according to actual needs and will not be described in detail here.

[0026] It should be noted that the air volume of the small air purifier 30 is selected according to actual needs and will not be described in detail here.

[0027] The two upper straps 40 are symmetrically arranged on both sides of the breathing mask 10 .

[0028] The upper strap 40 is made of transparent silicone.

[0029] The two lower ties 50 are symmetrically arranged on both sides of the small air purifier 30 .

[0030] The lower strap 50 may be made of nylon.

[0031] It should be noted that the two lower straps 50 can be fastened to the user by means of Velcro, or by means of a belt buckle. The specific fixing method is selected according to actual needs and will not be described in detail here.

[0032] The breathing mask 10 is provided with an air inlet and an air outlet.

[0033] It should be noted that the number of the air outlet holes may be one or more, for example, the number of the air outlet holes is two.

[0034] One end of the hose 20 away from the small air cleaner 30 is sealed and fixed to the air inlet of the breathing mask 10 .

[0035] It should be noted that the length of the hose 20 is selected according to actual needs and will not be described in detail here.

[0036] It should be noted that the hose 20 can be configured as a foldable telescopic tube structure, which is a prior art and will not be described in detail herein.

[0037] An outer flap 11 is arranged outside the air outlet of the breathing mask 10. The outer flap 11 is hinged on the upper side of the air outlet, and the outer flap 11 covers the corresponding air outlet.

[0038] It should be noted that the outer side of the air outlet of the breathing mask 10 refers to the side of the air outlet away from the user's nose.

[0039] An inner flap 12 is arranged inside the air inlet of the breathing mask 10. The inner flap 12 is hinged on the upper side of the air inlet and covers the air inlet.

[0040] It should be noted that the inner side of the air inlet of the breathing mask 10 refers to the side of the air inlet away from the hose 20 .

[0041] It should be noted that the outer flap 11 and the inner flap 12 are both made of transparent material.

[0042] It is understandable that the relevant personnel wear the small air purifier 30 on the head or waist through the lower strap 50, and then wear the respirator 10 on the nose through the upper strap 40 and adjust the tightness; start the small air purifier 30, the small air purifier 30 inhales the surrounding air and after high-efficiency filtration, it is transported to the air inlet of the respirator 10 through the hose 20; when the user inhales, the inner flap 12 automatically opens, and the outer flap 11 automatically closes under the action of gravity, allowing the purified air to enter the respirator 10 and be transported to the user's nasal cavity; when exhaling, the inner flap 12 automatically closes under the action of gravity, and at the same time, the outer flap 11 opens to discharge the exhaled gas to the outside of the respirator 10; in this way, the user can continue to inhale clean air and maintain the health of the respiratory tract.

[0043] It should be noted that sponge or soft rubber may be provided at the edge of the breathing mask 10 to seal the breathing mask 10 so as to facilitate the complete inhalation of clean fresh air purified by the small air purifier 30 and passing through the hose 20 .

[0044] It should be noted that the edge of the breathing mask 10 can be manufactured with different heights and depressions according to the shape, height, width and other characteristics of the human nose, face and upper lip; a flexible layer (not shown in the figure) can be set on the edge of the breathing mask 10, and the material of the flexible layer may include one or more combinations of soft plastic, sponge or rubber materials, which can seal the breathing mask 10 to facilitate the user to inhale all the clean fresh air purified by the small air purifier 30 and pass through the hose 20, while preventing the user from feeling uncomfortable due to marks caused by wearing it for a long time.

[0045] It should be noted that the flexible layer at the edge of the breathing mask 10 can be made thicker to accommodate different users. Specifically, the thickness of the flexible layer at the edge of the breathing mask 10 can be 3 cm to 5 cm. The flexible layer is a common structure in the prior art and will not be described in detail here.

[0046] Further, such as Figure 2 and Figure 3 As shown, protrusions are provided above the inner flap 12 and above the outer flap 11, and the protrusions are installed on the breathing mask 10.

[0047] It should be noted that a rubber sealing layer (not shown in the figure) can be provided on one side of the inner flap 12 and the outer flap 11 close to the breathing mask 10, so that the inner flap 12 and the outer flap 11 can fit on the breathing mask 10 more tightly.

[0048] It can be understood that by providing the protrusions, when the user exhales, the outer flap 11 flips up, and at this time, due to the obstruction of the corresponding protrusions, the outer flap 11 will not flip up to fit against the outer wall of the breathing mask 10, ensuring that when the user inhales, the outer flap 11 can smoothly flip down and return to its original position under the action of gravity; when the user inhales, the inner flap 12 flips up, and at this time, due to the obstruction of the corresponding protrusions, the inner flap 12 will not flip up to fit against the inner wall of the breathing mask 10, ensuring that when the user exhales, the inner flap 12 can smoothly flip down and return to its original position under the action of gravity.

[0049] It should be noted that the thickness (protrusion degree) of the bump is selected according to actual needs and will not be described in detail here.

[0050] The filter technology can remove harmful substances such as tiny particles in the air to ensure the quality of the air inhaled by the user; the breathing mask 10 and the hose 20 are made of soft and comfortable materials, which can fit the user's nose tightly to reduce discomfort; at the same time, the design of the strap also ensures the stability of the device; the device is small and light, easy to carry and use. Whether it is outdoor activities or daily travel, it can be easily worn; the transparent material design allows users to intuitively observe the operating status and internal conditions of the device, which is convenient for maintenance and care.

[0051] like Figure 4 and Figure 5 As shown, in another embodiment of the present application, a small air purifier 30 includes a housing 31 , a filter 34 , a fan 35 , and an energy storage module 36 .

[0052] The two lower ties 50 are respectively arranged on both sides of the outer shell 31 , and the air outlet 32 ​​is arranged on the outer shell 31 .

[0053] A grid plate 33 is provided on one side of the housing 31 .

[0054] It should be noted that the grid plate 33 can be installed on the housing 31 by bolts, and the grid plate 33 is used to roughly filter the gas entering the housing 31.

[0055] The filter screen 34 is disposed inside the housing 31 , and the filter screen 34 is located on one side of the grid plate 33 .

[0056] It should be noted that a limit block is provided inside the outer shell 31, and the limit block is located on the side of the filter 34 away from the grille plate 33, and the limit block is used to limit the position of the filter 34; the filter 34 can be movably placed in the outer shell 31, and the filter 34 can be cleaned or replaced by removing the grille plate 33.

[0057] The fan 35 is disposed inside the housing 31 , and the housing 31 is located on a side of the filter screen 34 away from the grille plate 33 .

[0058] An energy storage module 36 is disposed inside the housing 31 , and the energy storage module 36 is located on a side of the fan 35 away from the filter 34 .

[0059] The energy storage module 36 may be a battery.

[0060] It should be noted that a charging port is provided on the housing 31 , and the charging port is electrically connected to the charging post of the energy storage module 36 .

[0061] It should be noted that the air outlet 32 ​​is located on a side of the fan 35 away from the filter 34 .

[0062] like Figure 5 As shown, in another embodiment of the present application, the small air purifier 30 further includes an ultraviolet lamp 37 .

[0063] The ultraviolet lamp 37 is disposed inside the housing 31 , and is located on a side of the fan 35 away from the filter 34 .

[0064] It should be noted that the number of the ultraviolet lamps 37 may be one or more, for example, the number of the ultraviolet lamps 37 is two.

[0065] It is understandable that the power of the fan 35 is relatively small, and the fan 35 alone is not enough to blow up the inner flap 12. Instead, the inner flap 12 is mainly flipped by the suction force of the user's breathing to prevent excessive purified air from violently entering the human nasal cavity and causing discomfort to the user, and to prevent the inner flap 12 from being unable to effectively reset during exhalation, so that the gas exhaled from the user's lungs can forcefully enter the breathing mask 10 and be discharged through the air outlet of the breathing mask 10; in the present application, the fan 35 only serves to assist the gas to enter the interior of the small air purifier 30 and will not have much impact on the user's breathing.

[0066] It should be noted that the power of the fan 35 is selected according to actual needs. For example, the power of the fan 35 can be 5W. The specific power usage is not described in detail here.

[0067] It should be noted that the small air purifier 30 in the present application may not be provided with a fan 35, and the user can exhale and inhale only by relying on the function of the lungs themselves.

[0068] Further, such as Figure 5 As shown, in another embodiment of the present application, the small air purifier 30 further includes a negative ion generator 38 .

[0069] The negative ion generator 38 is disposed inside the housing 31 , and the negative ion generator 38 is located on a side of the fan 35 away from the filter 34 .

[0070] Further, such as Figure 5 As shown, in another embodiment of the present application, the small air purifier 30 further includes a gas sensing module 39 .

[0071] The gas sensing module 39 is disposed inside the housing 31 , and is located on a side of the fan 35 away from the filter 34 .

[0072] It should be noted that the gas sensing module 39 may be integrated with a PM2.5 sensor and a harmful gas sensor, both of which are existing technologies and will not be described in detail here.

[0073] It can be understood that when the small air purifier 30 is started, the fan 35 starts working and draws air from the outside; the air is first coarsely filtered through the grille plate 33 to remove larger particles and impurities; then, the air enters the interior of the outer shell 31 and is further filtered through the filter 34 to remove tiny particles and other harmful substances; the filtered air is transported to the hose 20 through the air outlet 32 ​​under the action of the fan 35, and finally enters the breathing mask 10 for the user to inhale.

[0074] The ultraviolet lamp 37, driven by the fan 35, performs ultraviolet sterilization treatment on the air after passing through the filter 34, further killing microorganisms such as bacteria and viruses in the air.

[0075] The negative ion generator 38 generates negative ions, which, along with the air, enter the hose 20 and the breathing mask 10 through the air outlet 32. The negative ions help improve the air quality and are beneficial to human health.

[0076] The gas sensing module 39 monitors the quality of the air inside the housing 31 in real time, including the concentration of harmful gases, etc.; when the gas sensing module 39 detects that the air quality does not meet the standard, it can automatically adjust the speed of the fan 35 or trigger an alarm to remind the user to replace the filter 34 or take other measures.

[0077] Through multiple filtration and sterilization treatments of the grille plate 33, the filter 34 and the ultraviolet lamp 37, it can ensure that the quality of the air inhaled by the user reaches a high level, effectively reducing the risk of respiratory diseases; the negative ions generated by the negative ion generator 38 help to improve air quality, promote human metabolism, enhance immunity, and have a positive effect on human health; the real-time monitoring function of the gas sensing module 39 can promptly detect and deal with air quality problems to ensure the continuous and efficient operation of the equipment. At the same time, the intelligent adjustment function also improves the ease of use and user experience of the equipment; the filter 34 can be movably placed in the housing 31 and fixed by a limit block. This design makes the cleaning and replacement of the filter 34 more convenient and extends the service life of the equipment; the energy storage module 36 provides long-lasting power support for the equipment to ensure normal use outdoors or without power.

[0078] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
