[0002] In recent years, due to changes in air quality caused by bacteria, viruses, and smog, and people's increased awareness of healthy living, people generally use masks (face shields) to protect themselves when going out. The main drawbacks of current masks (face shields) are: conventional masks and masks with exhalation valves have high breathing resistance, causing exhaled air to remain inside the mask, and they are not effective at removing bacteria, viruses, and smog. However, carrying a simple air purifier with you, and introducing purified air into the mask through a tube, can effectively remove bacteria, viruses, and particulate matter such as smog. Summary of the Invention

[0003] The purpose of this invention is to provide a clean air mask.

[0004] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0005] This utility model provides a clean air mask for covering the mouth and nose, comprising:

[0006] A mask body forming an inner cavity configured to cover at least a portion of the wearer's mouth and nose; the mask body includes a front wall located in front of the mouth and nose and a bottom side wall located below the mouth and nose, the bottom side wall being provided with vent holes.

[0007] A soft face mask, positioned on the edge of the mask body closest to the wearer's face;

[0008] An air delivery component is disposed in the inner cavity of the mask body and introduces external gas into the inner cavity; the air delivery component is provided with a purified air channel connecting the inner cavity of the mask body with the outside, and the air inlet of the purified air channel is located in the inner cavity of the mask body and is arranged towards the front wall of the mask body.

[0009] Furthermore, in the purified air mask provided by this utility model, a connector tube protrudes outward from the bottom side wall of the mask body, connecting the inner cavity of the mask body to the outside, and the connector tube is in fluid communication with the purified air channel of the air delivery component.

[0010] Furthermore, in the purified air mask provided by this utility model, the air delivery component includes a hollow tube body arranged around the purified air channel and a flow guide cover plate arranged above the hollow tube body. One end of the flow guide cover plate is connected to the hollow tube body, and the other end of the flow guide cover plate is separated from the hollow tube body to form the air inlet.

[0011] Furthermore, the flow guide cover includes an inner wall disposed on one side of the purified air channel and an outer wall facing the mouth and nose side. The plane of the inner wall of the flow guide cover is not perpendicular to the axial direction of the purified air channel, so that the flow direction of the gas entering the inner cavity is obliquely upward towards the front wall.

[0012] Furthermore, the flow guide cover is inclinedly disposed above the hollow tube body, and the plane on which the flow guide cover is located is not perpendicular to the axis of the purified gas channel, so that the airflow entering the inner cavity flows obliquely upward towards the front wall.

[0013] Furthermore, in the purified air mask provided by this utility model, the air delivery component further includes a connecting rod, which is disposed in the middle of the air inlet and divides the air inlet into two parts.

[0014] Furthermore, in the purified air mask provided by this utility model, the lower part of the hollow tube body is provided with a connecting tube for sealing connection with the connector tube. Preferably, the diameter of the connecting tube is smaller than that of the hollow tube body, so that when the connecting tube is inserted into the connector tube, the upper part of the connector tube is sealed to the hollow tube body.

[0015] Furthermore, in the air purification mask provided by this utility model, the air outlet is provided on the side of the bottom sidewall of the mask body near the wearer's mouth and nose.

[0016] Furthermore, the purified air mask provided by this utility model further includes a pair of straps for holding the mask body on the face, preferably, the pair of straps are arranged on both sides of the mask body.

[0017] Furthermore, in the purified air mask provided by this utility model, the soft mask is a silicone mask.

[0018] In a second aspect, this utility model provides a purification device for providing purified gas to the mouth and nose of a wearer, comprising a purifier for providing purified gas, a face mask, and an air supply pipe connecting the purification unit and the face mask, wherein the face mask is the aforementioned purified gas face mask.

[0019] The beneficial effects of this utility model are:

[0020] The air purification mask provided by this utility model has an air inlet that is not designed to face upwards. This means that the airflow delivered into the mask through the air delivery component is not sprayed directly towards the mouth and nose, but rather sprayed towards the front wall and flows into the mouth and nose along the front wall. This reduces the airflow velocity into the mouth and nose and makes it more uniform, so that the mouth and nose remain comfortable even under high airflow and long-term use.

[0021] The purified air mask provided by this utility model has a design in which "the air outlet is located on the bottom side wall and the air inlet faces the front wall of the mask body". This design ensures that the purified air entering the mask will not flow out directly from the air outlet, but will flow into the mouth and nose along the front wall of the mask. Moreover, the air exhaled through the mouth and nose can be directly discharged from the air outlet located on the bottom side wall, reducing the mixing with the purified air that has just entered the mask.

[0028] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0029] According to an embodiment of the present invention, a purifying air mask 100 is provided for covering the nostrils and mouth, such as... Figures 1-3 As shown, the air purification mask 100 includes: a mask body 1 for covering the wearer's nostrils and mouth, which forms a space (hereinafter referred to as "inner cavity") between itself and the wearer's face when worn, that is, an inner cavity is formed inside the mask body, and the inner cavity is configured to cover the wearer's mouth and nose. The mask body 1 includes a front wall 11 located in front of the mouth and nose and a bottom side wall 12 located below the nostrils, with an air outlet 120 on the bottom side wall 12; a soft mask 2, which is located on the edge of the mask body 1 near the wearer's face, for example, the soft mask 2 is connected (by snap-fit, glue, etc.) to the edge of the mask body 1 near the wearer's face; an air delivery component 3, which is located in the inner cavity of the mask body 1 and introduces external gas into the inner cavity; the air delivery component 3 is provided with a purified air channel 31 connecting the inner cavity of the mask body 1 with the outside, the air inlet 310 of the purified air channel 31 is arranged facing the front wall 11 of the mask body 1, and purified clean gas can be introduced into the inner cavity of the mask body 1 through the air inlet 310 of the purified air channel 31, thus providing clean gas for the wearer to breathe.

[0030] In this embodiment, the soft mask 2 is a silicone mask. This soft mask can be elastically deformed, making the mask fit more closely to the wearer's facial skin and improving the airtightness of the mask.

[0031] In this embodiment, a connector pipe 4 protrudes from the bottom sidewall 12 of the mask body 1, connecting the inner cavity of the mask body 1 to the outside. The connector pipe 4 is in fluid communication with the purified air channel 31 of the air supply component 3. The connector pipe 4 is a hollow tubular structure. The portion of the connector pipe 4 protruding outward from the bottom sidewall 12 is used to connect with other pipelines. For example, one end of another pipeline is connected to the purifier, and the other end is connected to the connector pipe 4, so that the clean air purified by the purifier can enter the inner cavity of the purified air mask 100 through the other pipelines and the connector pipe 4.

[0032] In this embodiment, refer to Figure 2 The air delivery component 3 includes a hollow tube body 311 surrounding the purified air passage 31 and a guide cover 312 disposed above the hollow tube body 311. One end of the guide cover 312 is connected to the hollow tube body 311, and the other end of the guide cover 312 is separated from the hollow tube body 311 to form an air inlet 310. The air inlet 310 is arranged facing the front wall 11 of the mask body 1. The airflow entering the inner cavity of the mask body 1 is not sprayed directly towards the mouth and nose, but is sprayed towards the front wall.

[0033] Specifically, refer to Figure 2 The airflow guide cover 312 includes an inner wall 315 disposed on one side of the purified air channel 31 and an outer wall 316 facing the mouth and nose. The inner wall 315 of the airflow guide cover 312 is inclined, that is, the plane of the inner wall of the airflow guide cover 312 is not perpendicular to the axis of the purified air channel 31. If the purified air channel 31 has a quasi-cylindrical structure, the axis of the purified air channel 31 is in the same direction as the central axis. With this design, the airflow entering the inner cavity of the mask body 1 flows obliquely upward towards the front wall, and the airflow does not blow perpendicularly to the front wall, which can better allow the airflow to flow into the mouth and nose along the front wall. Specifically, refer to Figure 2 The air delivery component 3 includes a hollow tube body 311 surrounding the purified air channel 31, and a guide cover 312 inclined above the hollow tube body 311. If the guide cover is a flat plate of uniform thickness, the plane of the guide cover 312 is not perpendicular to the axis of the purified air channel 31. If the purified air channel 31 has a cylindrical structure, the axis of the purified air channel 31 is in the same direction as the central axis. This design ensures that the airflow entering the inner cavity of the mask body 1 flows obliquely upward towards the front wall, and the airflow does not blow perpendicularly to the front wall, allowing the airflow to flow more smoothly into the nose and mouth along the front wall. Because the guide cover is a flat plate of uniform thickness, its inclined placement above the hollow tube body 311 allows the inner wall of the guide cover to be inclined.

[0034] In this embodiment, the air delivery component 3 also includes a connecting rod 313. The connecting rod 313 is disposed in the middle of the air inlet 310, dividing the air inlet 310 into two parts. One end of the connecting rod 313 is connected to the guide cover plate 312, and the other end of the connecting rod 313 is connected to the hollow tube body 311. The lower part of the hollow tube body 311 is provided with a connecting pipe 314, which is used for sealing connection with the connector pipe 4. The air delivery component 4 can be an integrally formed structure, that is, the hollow tube body 311, the guide cover plate 312, and the connecting rod 313 are integrally formed, or the hollow tube body 311, the guide cover plate 312, and the connecting rod 313 can be processed separately and then spliced ​​together. Through the design of the connecting rod, the airflow can be directed to the two nostrils respectively, which conforms to the ergonomic design.

[0035] In this embodiment, refer to Figure 2The air inlet 310 formed by the flow guide cover 312 and the hollow tube body 311 is larger in the middle than at both ends. The two ends are the connection points between the flow guide cover 312 and the hollow tube body 311.

[0036] In this embodiment, the diameter of the connecting tube 314 is smaller than the diameter of the hollow tube body 311, so that when the connecting tube 314 is inserted into the connector tube 4, the top of the connector tube 4 is sealed to the hollow tube body 311.

[0037] In this embodiment, the bottom sidewall 12 of the mask body 1 has six air outlets 120 on the side near the mouth and nose (the number of air outlets can be adjusted according to actual conditions). The six air outlets are divided into two groups of three. The connector tube 4 and the air delivery component 3 are disposed on the bottom sidewall 12 of the mask body 1, and the two groups of air outlets are located on both sides of the connector tube 4 and the air delivery component 3, respectively. The air outlets provided on the bottom sidewall 12 of the mask body 1 in this utility model are used to expel the air exhaled by the wearer from the mouth and nose from the mask. In addition, a one-way valve can be provided in the air outlet 120 to better ensure that the air only goes out and does not enter, thus ensuring the cleanliness of the air inside the mask body 1.

[0038] The purified air mask of this embodiment also includes a pair of straps (not shown in the figures) for holding the mask body 1 on the face. In this embodiment, the mask body has ear loops on both sides, and the pair of straps are fixedly connected to the ear loops on both sides of the mask body. In one embodiment, the pair of straps may be a pair of ear loops, each hanging on one of the two ears. In another embodiment, the pair of straps may also be a pair of headbands, each tied to the head to hold the mask on the face.

[0039] The air outlet of the purified air mask provided in this embodiment is located on the bottom side wall, and the air outlet is positioned facing the front wall of the mask body. The air outlet is lower than the air outlet position where external gas enters the inner cavity, and the air outlet faces the mask body. With this design, the purified gas entering the mask will not flow directly out of the air outlet, but will flow into the mouth and nose along the front wall of the mask body. Moreover, the gas exhaled through the mouth and nose can be directly discharged from the air outlet located on the bottom side wall, reducing the mixing with the purified gas that has just entered the mask.

[0040] An embodiment of this utility model also provides a purification device for providing purified gas to the mouth and nose. The device includes a purifier for providing purified gas, a purified gas mask, and an air supply pipe connecting the purification unit and the mask. The purified gas mask 100 is the purified gas mask provided in the above embodiment. One end of the air supply pipe is connected to a connector pipe 4 of the purified gas mask 100, and the other end is connected to the purified gas outlet of the purifier. The purified gas provided by the purifier is delivered to the air supply component of the purified gas mask through the air supply pipe and connector pipe 4. The purified gas is discharged into the inner cavity of the mask body through the air inlet 310 of the purified gas channel 31 of the air supply component and delivered to the mouth and nose.

[0041] In this embodiment, the purifier that provides the purified gas can be any device capable of purifying gas to obtain sterile, radiation-free, and virus-free pure gas.
