The mask is the above-mentioned purified gas mask.

[0019] Advantages of the present invention:

[0020] In the purified gas mask provided by the present invention, the air inlet of the air supply member is not directly designed upward, so that the air flow of the gas sent into the mask through the air supply member is not sprayed directly towards the mouth and nose, but the air flow is sprayed towards the front wall and flows into the mouth and nose along the front wall, so that the air speed of the gas entering the mouth and nose becomes smaller and more uniform. Under the conditions of large air volume and long-term use, the mouth and nose still remain comfortable.

[0021] The purification gas mask provided by the present invention is designed such that "the air outlet is provided on the bottom side wall and the air inlet faces the front wall of the mask body", so that the purified gas entering the mask does not directly flow out from the air outlet, but flows along the front wall of the mask into the mouth and nose, and the gas exhaled through the mouth and nose can directly be discharged from the air outlet located on the bottom side wall, reducing the mixing with the purified gas that has just entered the mask.

[0028] In addition, the technical features involved in different embodiments of the present invention 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 purified gas mask 100 is provided, which is used to cover the nostrils and mouth, as Figures 1 - 3 shown. The purified gas mask 100 includes: a mask body 1, which is used to cover the nostrils and mouth of the wearer, and can form a space (hereinafter referred to as "inner cavity") between the mask body 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 mouth and nose of the wearer. The mask body 1 includes a front wall 11 in front of the mouth and nose and a bottom side wall 12 below the nostrils. An air outlet hole 120 is provided on the bottom side wall 12; a soft mask 2, which is arranged at the edge of the mask body 1 close to the wearer's face. For example, the soft mask 2 is connected (which can be snap-connected, glued, etc.) to the edge of the mask body 1 close to the wearer's face; an air supply member 3, which is arranged in the inner cavity of the mask body 1 and introduces external gas into the inner cavity; a purified gas channel 31 communicating the inner cavity of the mask body 1 with the outside is provided on the air supply member 3, and the air inlet 310 of the purified gas channel 31 in the inner cavity of the mask body 1 is arranged facing the front wall 11 of the mask body 1. Through the air inlet 310 of the purified gas channel 31, the purified clean gas can be introduced into the inner cavity of the mask body 1, so that clean gas can be provided for the wearer to breathe.

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

[0031] In this embodiment, a joint pipe 4 communicating the inner cavity of the mask body 1 with the outside is convexly provided on the bottom side wall 12 of the mask body 1. The joint pipe 4 is in fluid communication with the purified gas channel 31 of the air supply member 3. The joint pipe 4 is a hollow tubular structure. The part of the joint pipe 4 protruding outward from the bottom side wall 12 is used to be connected with other pipelines. For example, one end of other pipelines is connected to a purifier and the other end is connected to the joint pipe 4, so that the clean air purified by the purifier can enter the inner cavity of the purified gas mask 100 through other pipelines and the joint pipe 4.

[0032] In this embodiment, with reference toFigure 2 , the air supply member 3 includes a hollow tube body 311 disposed around the purified gas passage 31, and a diversion cover plate 312 disposed above the hollow tube body 311. One end of the diversion cover plate 312 is connected to the hollow tube body 311, and the other end of the diversion cover plate 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 the gas airflow is sprayed towards the front wall direction.

[0033] Specifically, referring to Figure 2 , the diversion cover plate 312 includes an inner wall 315 disposed on one side of the purified gas passage 31 and an outer wall 316 facing the mouth and nose side. The inner wall 315 of the diversion cover plate 312 is inclined, that is, the plane where the inner wall of the diversion cover plate 312 is located is not perpendicular to the axial direction of the purified gas passage 31. If the purified gas passage 31 is a quasi-cylindrical structure, the axial direction of the purified gas passage 31 is the same as the direction of the central axis. Through such a design, the flow direction of the airflow entering the inner cavity of the mask body 1 is to flow obliquely upward towards the front wall, and the airflow does not blow vertically against the front wall, which can better make the airflow flow along the front wall into the mouth and nose. Specifically, referring to Figure 2 , the air supply member 3 includes a hollow tube body 311 disposed around the purified gas passage 31, and a diversion cover plate 312 inclinedly disposed above the hollow tube body 311. If the diversion cover plate is a flat plate with a uniform thickness, the plane where the diversion cover plate 312 is located is not perpendicular to the axial direction of the purified gas passage 31. If the purified gas passage 31 is a quasi-cylindrical structure, the axial direction of the purified gas passage 31 is the same as the direction of the central axis. Through such a design, the flow direction of the airflow entering the inner cavity of the mask body 1 is to flow obliquely upward towards the front wall, and the airflow does not blow vertically against the front wall, which can better make the airflow flow along the front wall into the mouth and nose. Exactly because the diversion cover plate is a flat plate with a uniform thickness, the diversion cover plate is inclinedly disposed above the hollow tube body 311, so that the inner wall of the diversion cover plate can be inclinedly disposed.

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

[0035] In this embodiment, referring to Figure 2, the middle part of the air inlet 310 formed by the diversion cover plate 312 and the hollow tube body 311 is larger than both ends. Both ends are the connection parts of the diversion cover plate 312 and the hollow tube body 311.

[0036] In this embodiment, the diameter of the connecting pipe 314 is smaller than that of the hollow tube body 311, so that when the connecting pipe 314 is inserted into the joint pipe 4, the upper part of the joint pipe 4 is hermetically arranged with the hollow tube body 311.

[0037] In this embodiment, six air outlet holes 120 (the number of air outlet holes can be adjusted according to actual situations) are provided on one side of the bottom side wall 12 of the mask body 1 close to the mouth and nose. Every three of the six air outlet holes form a group, and are divided into two groups. The joint pipe 4 and the air supply member 3 are arranged on the bottom side wall 12 of the mask body 1, and the two groups of air outlet holes are respectively located on both sides of the joint pipe 4 and the air supply member 3. The air outlet holes provided on the bottom side wall 12 of the mask body 1 in the present invention are used to discharge the gas exhaled by the wearer from the mouth and nose out of the mask. In addition, a one-way valve can be provided in the air outlet 120 to better allow the gas to only go out and not come in, and ensure the cleanliness of the gas in the inner cavity of the mask body 1.

[0038] The purifying gas mask of this embodiment further includes a pair of straps (not shown in the figure) for holding the mask body 1 on the face. In this embodiment, hanging ears are provided on both sides of the mask body, and a pair of straps are fixedly connected to the hanging ears on the mask body on both sides of the mask body. In one embodiment, the pair of straps can be a pair of hanging ear straps, which are respectively hung on two ears. In another embodiment, the pair of straps can also be a pair of head straps, which are respectively tied on the head to hold the mask on the face.

[0039] In the purifying gas mask provided in this embodiment, the air outlet holes are arranged on the bottom side wall, the air outlet is arranged towards the front wall of the mask body, the air outlet holes are lower than the position of the air outlet where the external gas enters the inner cavity, and the air outlet is towards the mask body. Through such a design: the purified gas entering the mask will not directly flow out from the air outlet holes, 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 holes located on the bottom side wall, reducing the mixing with the purified gas just entering the mask.

[0040] An embodiment of the present invention further provides a purifying device for supplying purified gas to the mouth and nose, including a purifier for supplying purified gas, a purifying gas mask, and an air supply pipe connecting the purifying unit and the mask. The purifying gas mask 100 is the purifying gas mask provided in the above embodiment. One end of the air supply pipe is communicated with the joint pipe 4 of the purifying gas mask 100, and the other end of the air supply pipe is communicated with the purified gas outlet of the purifier. The purified gas provided by the purifier is transported to the air supply member of the purifying gas mask through the air supply pipe and the joint pipe 4, and the purified gas is discharged into the inner cavity of the mask body through the air inlet 310 of the purification gas channel 31 of the air supply member and sent to the mouth and nose of the person.

[0041] In this embodiment, the purifier for purifying gas can be any device that can purify gas to obtain pure gas free of bacteria, radiation, and viruses.
