[0002] There are many types of respiratory diseases, which occur frequently and cause varying degrees of harm to human health. In particular, allergic respiratory diseases such as asthma and allergic rhinitis have been seriously affecting the physical and mental health and quality of life of patients. In order to prevent children from getting allergic when going out during allergy-prone seasons such as the flowering season, they will wear anti-allergy nasal masks when going out for prevention. A nasal mask is a medical supply, mainly used in the process of medical treatment and care to cover the nose part of the patient to achieve specific medical purposes.

[0003] The prior art, such as the patent with the publication number CN204483135U, discloses a health care mouth and nose mask, which includes an outer cover body and an inner cover body. There is a certain distance between the outer cover body and the inner cover body. The air outside the mask enters around the outer cover body and enters the mask through the main ventilation holes of the inner cover body along the gap between the inner and outer layers. The exhaled gas also exits the mask through the same path. Part of the heat of the gas exhaled by people remains inside the inner cover body, slowing down the direct stimulation of cold air to the respiratory tract and at the same time slowing down the heat dissipation of the exhaled gas. By the cooperation of the main cover body and the inner cover body, it is possible to avoid the direct impact of cold air on the human respiratory tract and appropriately warm the inhaled air. This health care mouth and nose mask can be used to prevent and treat respiratory diseases such as colds, allergic asthma, and allergic rhinitis, and is also helpful for adsorbing air impurities and improving sleep quality.

[0040] In addition, the technical features involved in different embodiments of the present utility model described above can be combined with each other as long as they do not conflict with each other.

[0041] The present utility model provides a Figures 1 to 5 child anti-allergy nose mask as shown in the figure, aiming to solve the drawback that the existing nose mask needs to be removed and wiped by hand when it is blocked.

[0042] The child anti-allergy nose mask mainly includes: a nose mask body 1, filter holes, and a cleaning unit. The nose mask body 1 is used to be fixed on the user's nose and form a closed cavity with the nose. The filter holes are arranged on the outer surface of the nose mask body 1, and the filter holes communicate with the closed cavity. The filter holes are used to filter air.

[0043] Specifically, during actual use, the nose mask body 1 tightly fits on the face around the user's nose. A closed cavity is formed between the nose mask body 1 and the user, so that when the user breathes, the gas in the closed cavity can only exchange with the outside air through the filter holes. The filter holes are used to filter air, so that the user can obtain clean air filtered by the filter holes when inhaling.

[0044] The cleaning unit is arranged on the outer surface of the nose mask body 1. The cleaning unit is used to clean the filter holes. The cleaning unit includes a scraping strip 42. The scraping strip 42 is rotatably arranged on the nose mask body 1. The scraping strip 42 is used to scrape the filter holes for cleaning. During actual use, since the cleaning unit is arranged on the outer surface of the nose mask body 1, the user can directly perform blind operation with hands (drive the scraping strip 42 to rotate back and forth with hands), so that the scraping strip 42 scrapes the filter holes. The scraping strip 42 can scrape off the fluff and other substances attracted by breathing in or around the filter holes, avoiding the situation that the nose mask body 1 needs to be removed for cleaning when it is blocked.

[0045] However, the ventilation holes of the existing nose masks need to filter air. After long-term use when going out, the ventilation holes may be blocked by fluff and other substances attracted by breathing. And the existing nose masks usually do not have the function of cleaning the ventilation holes. When they are blocked, they need to be removed and wiped by hand, which is neither hygienic nor convenient, and affects the wearing comfort.

[0046] By setting the cleaning unit, when the filter holes are blocked by fluff and other substances attracted by breathing, the user can directly perform blind operation to use the scraping strip 42 to scrape and clean the filter holes. When encountering stubborn blockages, the scraping strip 42 can be used to scrape and clean repeatedly, without the need to remove it and wipe it by hand. The cleaning process is simple and the wearing comfort is also enhanced.

[0047] In some embodiments, such as Figures 2 to 4As shown in the figure, the filter holes include: ventilation holes and a filter plate 3. The ventilation holes are provided on the outer surface of the nasal mask body 1, and the filter holes communicate with the sealed cavity. The filter plate 3 is arranged in a matching manner on the ventilation holes, and the filter plate 3 is used to filter the air flowing through the ventilation holes. Specifically, there are two filter holes, and the two nostrils of the user face the two filter holes, shortening the distance between the filter holes and the nostrils, so that fresh air can be obtained more quickly during inhalation.

[0048] In some embodiments, as Figure 4 , Figure 5 shown in the figure, the cleaning unit includes: a rotating ring 41. The rotating ring 41 is rotatably arranged on the nasal mask body 1, a scraping strip 42 is arranged on the rotating ring 41, the scraping strip 42 abuts against the surface of the filter plate 3, and the scraping strip 42 is driven by the rotating ring 41 to scrape the surface of the filter plate 3. Specifically, the scraping strip 42 can be arranged on the outer surface of the rotating ring 41, so that the rotating ring 41 and the scraping strip 42 form a "7" - shaped structure; it can also be arranged on the inner surface of the rotating ring 41, so that the rotating ring 41 and the scraping strip 42 form a "day" - shaped structure; the scraping strip 42 is preferably arranged on the inner surface of the rotating ring 41. When in use, rotating the rotating ring 41 can drive the scraping strip 42 to clean the filter plate 3, reducing the chance of contact between the scraping strip 42 and the user's hand, which is more hygienic.

[0049] In some embodiments, as Figures 2 to 5 shown in the figure, there are several filter holes, and the rotating ring 41 corresponds to each filter hole one by one.

[0050] The cleaning unit further includes: a handwheel 43. The handwheel 43 is rotatably arranged on the nasal mask body 1. The handwheel 43 meshes with several rotating rings 41 respectively, and the handwheel 43 is used to drive several rotating rings 41 to rotate. Specifically, the handwheel 43 is arranged between several rotating rings 41. During actual use, the handwheel 43 can be rotated by hand to drive several rotating rings 41 to rotate, thereby driving several scraping strips 42 to clean the filter plate 3, which is convenient for the patient to operate blindly.

[0051] In some embodiments, as Figures 1 to 4 shown in the figure, the nasal mask body 1 has a bottom end facing the user's chin. The filter holes are arranged on the bottom surface of the nasal mask body 1, which is convenient for the user to blindly clean the filter holes by hand. The filter plate 3 is arranged at the lower opening of the ventilation hole. The shape of the rotating ring 41 is annular, the scraping strip 42 is arranged inside the rotating ring 41, and the rotating ring 41 is coaxially arranged with the ventilation hole. Specifically, the filter plate 3 can be flush with the outer surface of the nasal mask body 1 or the filter plate 3 protrudes from the outer surface of the nasal mask body 1, which is convenient for the scraping strip 42 to scrape the filter plate 3.

[0052] In some embodiments, the cleaning unit further includes: a spring (not shown in the figure), which is connected between the nasal mask body 1 and the hand wheel 43, and is used to drive the hand wheel 43 to rotate. In actual use, the user can drive the plurality of rotating rings 41 to rotate by rotating the hand wheel 43, thereby driving the plurality of scraping strips 42 to clean the filter plate 3, and at the same time, the spring can be "charged", and when the patient stops rotating the hand wheel 43, the spring can continue to drive the hand wheel 43 to rotate, thereby continuing to drive the plurality of scraping strips 42 to clean the filter plate 3, thereby extending the time for cleaning the filter plate 3 and enhancing the cleaning effect.

[0053] Specifically, the cleaning unit further includes: a deceleration unit, through which the spring is connected to the hand wheel 43 in a transmission manner. When the spring is "charged" and the hand wheel 43 is driven to rotate, the deceleration unit can slow down the rotation speed of the hand wheel 43, thereby extending the time for cleaning the filter plate 3 and enhancing the cleaning effect. Preferably, the cleaning unit further includes: a ratchet unit, and when the patient rotates the hand wheel 43 to "charge" the spring, the deceleration unit does not work; when the spring is "charged" and the hand wheel 43 is driven to rotate, the deceleration unit works, so that the patient can "charge" the spring conveniently.

[0054] In some embodiments, Figures 2 to 4 As shown in the figure, the children's anti-allergic nose mask also includes: a nose clip unit, which is arranged on the nose mask body 1 and in the closed cavity, and is used to be fixed on the user's nose. Preferably, the nose clip unit is arranged at the center of the bottom of the inner surface of the nose mask body 1, so as to be conveniently fixed to the user's nose.

[0055] In some embodiments, Figures 2 to 4 As shown in , the nose clip unit includes: a sliding opening 51, a slider 52 and an elastic clip 53. The sliding opening 51 is arranged on the nose mask body 1 through and through, and the slider 52 is arranged in the sliding opening 51 in a sealing and sliding manner toward the opening direction of the sliding opening 51. The elastic clip 53 is arranged at one end of the slider 52 facing the closed cavity, and the elastic clip 53 is used to be fixed on the user's nose. In actual use, the user can adjust the position of the elastic clip 53 through the end of the slider 52 away from the closed cavity, so that the elastic clip 53 is moved to a suitable position and then fixed on the user's nose. Preferably, the nose clip unit also includes: a soft cover, and the bottom surface of the nose mask body 1 is fixedly connected with a soft cover corresponding to the sliding opening 51, which can be in close contact with the slider 52 to enhance the airtightness between the two.

[0056] In some embodiments, Figure 2 , Figure 3 As shown in , the elastic clip 53 is in a "U" shape;

[0057] The nose clip unit further includes: a limiting portion, which is arranged on the nose mask body 1 and is used to limit the moving distance of the elastic clip 53;

[0058] Two magnetic attraction parts are respectively arranged at two ends of the elastic clip 53. The two magnetic attraction parts attract each other and are used to drive the elastic clip 53 to clamp, so that it can be better fixed on the nose of the user.

[0059] In some embodiments, as Figures 1 to 4 shown in, the children's anti-allergy nose mask further includes: an everted edge 11 and a headband unit 2. The edge of the nose mask body 1 in contact with the user expands away from the nose mask body 1 to form the everted edge 11. A silica gel layer 12 is arranged on the surface of the everted edge 11 facing the user, which can increase the contact area between the nose mask body 1 and the user and enhance the comfort of the patient when wearing;

[0060] The headband unit 2 includes: an elastic band 23, two clamping blocks 22 and two clamping grooves 21. The two clamping blocks 22 are respectively arranged at two ends of the elastic band 23. The two clamping grooves 21 are arranged on the nose mask body 1 at intervals. The two clamping blocks 22 are respectively detachably connected to the two clamping grooves 21. When in use, the annular structure formed by the elastic band 23 and the nose mask body 1 can be sleeved on the head of the user, and the nose mask body 1 can be better fixed on the face of the user through the elastic band 23.

[0061] In summary, a children's anti-allergy nose mask is provided, which includes a nose mask body, filter holes and a cleaning unit. The nose mask body is used to be fixed on the nose of the user and form a closed cavity with the nose. The filter holes are arranged on the outer surface of the nose mask body, and the filter holes are communicated with the closed cavity. The filter holes are used to filter air. The cleaning unit is arranged on the outer surface of the nose mask body. The cleaning unit is used to clean the filter holes. The cleaning unit includes a scraping strip.
