Description

Technical Field

[0001] This utility model relates to the field of respiratory mask technology, specifically to an intelligent air-supplying respiratory mask. Background Technology

[0002] In special scenarios such as medical emergency response, industrial protection, and military operations, wearers often need to use closed-loop breathing masks for extended periods to isolate harmful gases or maintain oxygen supply. Breathing masks are designed to be worn over the mouth and nose to filter the air entering and exiting the nose and mouth, effectively preventing harmful gases, dust, and droplets from entering or exiting the wearer's mouth and nose, thus providing effective protection.

[0003] In existing technology, a fan is installed inside the air inlet. The fan's power is relatively low, resulting in poor assisted breathing effect of the breathing mask. The fan has a built-in power supply, which is located inside the air inlet. This built-in power supply significantly occupies the installation space of the fan body, resulting in limited installation and storage space for the fan body, thus restricting the fan size. Furthermore, the small gap between the fan and the air inlet prevents the fan from adequately delivering gas.

[0004] Furthermore, the fan's limited battery life negatively impacts the wearer's experience. When the wearer replaces the built-in power supply, the air intake of the face mask is opened. Frequent opening of the air intake can affect the connection between the air intake and the fan, thus reducing structural stability. Utility Model Content

[0058] Example 1

[0059] Please see Figures 1-4 and Figure 6 As shown, this embodiment discloses an intelligent air-supply breathing mask, including a mask 1, a mobile power supply 2, a control mechanism 3, a one-way valve 4, a fan 5, a housing mechanism 6, a connecting mechanism 7, and a filter box 9.

[0060] The mask 1 has an air inlet 11 and an air outlet 12 on its outer side. Both the air inlet 11 and the air outlet 12 are connected to the inner cavity of the mask 1. The air inlet 11 is equipped with a one-way valve 4, ensuring that outside air can only enter the inner cavity of the mask 1 through the air inlet 11. The air outlet 12 is also equipped with a one-way valve 4, ensuring that air inside the mask 1 can only be discharged to the outside through the air outlet 12. A connecting mechanism 7 is detachably connected to the air inlet 11 or the air outlet 12, and a fan 5 is installed within the connecting mechanism 7. The fan 5 is used to ventilate the inner cavity of the mask 1. A filter box 9 is located on the outer side of the mask 1. The end of the connecting mechanism 7 away from the mask 1 is adapted to be detachably connected to the filter box 9.

[0061] In this embodiment, there is one fan 5 and one connecting mechanism 7. The fan 5 is mounted on the air inlet 11 via the connecting mechanism 7 and is used to deliver air from the outside of the mask 1 to the inner cavity of the mask 1. The fan 5 is located on the side of the one-way valve 4 away from the inner cavity of the mask 1. The filter box 9 is mounted on the connecting mechanism 7 and is located at the air inlet end of the fan 5, that is, the fan 5 is placed between the one-way valve 4 and the filter box 9. The filter box 9 used on the mask 1 is prior art and will not be described in detail.

[0062] The receiving mechanism 6 is detachably disposed on the outside of the mask 1. The inner cavity of the receiving mechanism 6 is adapted to house the mobile power supply 2, or the control mechanism 3, or both the mobile power supply 2 and the control mechanism 3. A first hole 611 is provided on the receiving mechanism 6, which is adapted to connect the inner cavity of the receiving mechanism 6 and the inner cavity of the mask 1.

[0063] The control mechanism 3 is electrically connected to the power supply 2 and the fan 5 respectively. The control mechanism 3 is suitable for detecting the air pressure data inside the mask 1 and the air intake flow rate of the air inlet 11, and controlling the fan 5 to perform corresponding actions based on the detection results.

[0064] In this embodiment, there is one portable power source 2, used to supply power to the fan 5. Preferably, the portable power source 2 is a rechargeable portable power source. There are two housing mechanisms 6.

[0065] For details, please refer to Figures 4-5 As shown, the mask 1 is designed to conform to the proportions of the human face. The mask 1 has a symmetrical structure. Both the air inlet 11 and the air outlet 12 are located in the center of the mask 1, with the air inlet 11 positioned above the air outlet 12. Two receiving mechanisms 6 are symmetrically distributed on the mask 1, located on the left and right sides of the air outlet 12. One receiving mechanism 6 houses a mobile power supply 2, while the other receiving mechanism 6 houses a control mechanism 3 and a counterweight to ensure that the weight distribution on both sides of the mask 1 is equal, thereby improving user comfort.

[0066] Furthermore, the mask 1 has a silicone sealing ring 8 along its edge. The silicone sealing ring 8 is designed to contact the user's cheek, improving user comfort. Two ear loops 14 are symmetrically arranged on the outer side of the mask 1. The ear loops 14 are located near the edge of the mask 1 and on the left and right sides of the air inlet 11. The ear loops 14 are designed to connect to the straps, allowing the user to wear the mask 1 on their face using the straps.

[0067] Please see Figure 3 As shown, the control mechanism 3 includes a control main board 31, a pressure sensor, and an airflow sensor. The control main board 31 is housed within the receiving mechanism 6. The pressure sensor is located within the inner cavity of the mask 1 or within the receiving mechanism 6 to detect the pressure data within the inner cavity of the mask 1. When the pressure sensor is located within the receiving mechanism 6, it detects the pressure data within the inner cavity of the mask 1 through the first hole 611. When the pressure sensor is located within the inner cavity of the mask 1, it directly detects the pressure data within the inner cavity of the mask 1.

[0068] In this embodiment, a pressure sensor is installed inside the mask 1. An airflow sensor is installed inside the air inlet 11 to detect the airflow rate at the air inlet 11. Specifically, the airflow sensor is installed on the mask 1 and positioned at the air outlet of the air inlet 11. The control board 31 is electrically connected to the power bank 2, the fan 5, the pressure sensor, and the airflow sensor. The control board 31 is adapted to control the fan 5 to perform corresponding actions based on the pressure data inside the mask 1 and the airflow rate at the air inlet 11.

[0069] Specifically, the control board 31 is adapted to adjust the speed of the fan 5 based on the air pressure data inside the mask 1, thereby ensuring that the user can breathe smoothly. Furthermore, when the airflow at the air inlet 11 exceeds a threshold, the control board 31 is adapted to control the fan 5 to slow down, so as to prevent excessive air from being discharged into the mask 1 through the air inlet 11 from interfering with the user's normal breathing.

[0070] In this embodiment, the control motherboard 31 is a PLC controller. The control motherboard 31 is connected to the mobile power supply 2, the fan 5, the air pressure sensor, and the airflow sensor via cables. The first hole 611 allows the cables inside the mechanism 6 to enter the inner cavity of the mask 1.

[0071] Furthermore, the control mechanism 3 also includes an infrared sensor. The infrared sensor is installed inside the cavity of the mask 1. The infrared sensor is electrically connected to the control motherboard 31. The infrared sensor is used to detect whether the mask 1 is being worn by a user, that is, whether a person's face is inside the mask 1. When the user is wearing the mask 1, the control motherboard 31 controls the fan 5 to start based on the infrared sensor's detection result, so that the fan 5 can ventilate the cavity of the mask 1. When the mask 1 is not in use (i.e., the mask 1 is not being worn), the control motherboard 31 controls the fan 5 to stop rotating based on the infrared sensor's detection result.

[0072] Please see Figures 3-6 As shown, the receiving mechanism 6 includes a receiving box 61 and a sealing cover 62. The receiving box 61 is a hollow structure with an opening at the second end. The first end of the receiving box 61 is detachably connected to the face mask 1. The second end of the receiving box 61 is detachably connected to the sealing cover 62. In this embodiment, the first end of the receiving box 61 is threadedly connected to the face mask 1, and the second end of the receiving box 61 is threadedly connected to the sealing cover 62.

[0073] In this embodiment, a mobile power supply 2 is installed in the housing box 61 of one housing mechanism 6, and a control motherboard 31 is installed in the housing box 61 of the other housing mechanism 6.

[0074] Furthermore, a first hole 611 is provided on the end face of the first end of the housing 61. A corresponding second hole 13 is provided on the face mask 1. The second hole 13 is adapted to communicate with the first hole 611, so that the cable inside the housing 61 can enter the inner cavity of the face mask 1, thereby allowing the control board 31 to be connected to the power bank 2, the fan 5, the air pressure sensor, and the airflow sensor via cables. The cables in the inner cavity of the face mask 1 are fixed to the inner wall of the face mask 1 (not shown in the figure). The housing mechanism 6 is provided with a sealing cover 62 to prevent air from the outside of the face mask 1 from entering the inner cavity of the face mask 1 through the second hole 13. In addition, the sealing cover 62 also effectively protects the power bank 2 and the control board 31.

[0075] Please see Figure 1 and Figure 7As shown, the connecting mechanism 7 includes a connecting sleeve 71 and a protective cover 72. The connecting sleeve 71 is a hollow structure with openings at both ends. The connecting sleeve 71 is located on the outside of the face mask 1. The first end of the connecting sleeve 71 is detachably connected to the air inlet 11. The fan 5 is adapted to be installed inside the connecting sleeve 71. The first end of the protective cover 72 is adapted to be detachably connected to the second end of the connecting sleeve 71. The protective cover 72 has a through hole 721 to allow the inner cavity of the connecting sleeve 71 to communicate with the outside. The second end of the protective cover 72 is adapted to be detachably connected to the filter box 9.

[0076] In this embodiment, the air inlet 11 is provided with a connecting protrusion, and the first end of the connecting sleeve 71 is adapted to engage with the connecting protrusion. The first end of the protective cover 72 is adapted to be threadedly connected to the connecting sleeve 71. The second end of the protective cover 72 is provided with a connecting protrusion, which is adapted to engage with the filter box 9. A through hole 721 is formed in the center of the protective cover 72.

[0077] Furthermore, to ensure smooth airflow, the connecting mechanism 7 also includes a fixing plate 73. The fixing plate 73 is fixed inside the connecting sleeve 71. The axis of the connecting sleeve 71 is perpendicular to the fixing plate 73. The fixing plate 73 has ventilation holes 731. The fixing plate 73 has four support columns 74. The four corners of the fan 5 are threadedly connected to the support columns 74 via bolts. A gap exists between the fan 5 and the fixing plate 73 to allow for smooth airflow.

[0078] When the fan 5 is running, the air outside the mask 1 passes through the filter box 9, the through hole 721, the fan 5, the vent 731 and the air inlet 11 in sequence, and finally enters the inner cavity of the mask 1.

[0079] In this embodiment, by connecting the inner cavity of the receiving box to the inner cavity of the mask, the control mechanism can effectively monitor the condition of the mask's inner cavity, thereby effectively controlling the operation of the fan to enhance the mask's assisted breathing effect. By placing the fan and the power bank in different cavities, each has more storage space, allowing the fan to deliver gas more efficiently and improving its endurance. Replacing the power bank does not affect the connection between the air inlet and the fan. Compared to a built-in power supply located within the fan, the power bank of this invention has more storage space, meaning its volume can be increased, thus enhancing its endurance. The dual-receiving mechanism creates a symmetrical structure for the intelligent air-supplying breathing mask, resulting in an aesthetically pleasing and practical design.

[0080] Example 2

[0081] The difference between this embodiment and Embodiment 1 is that in this embodiment, there are two power banks 2.

[0082] In this embodiment, there is one fan 5 and one connecting mechanism 7. The fan 5 is mounted on the air inlet 11 via the connecting mechanism 7, and the filter box 9 is detachably connected to the second end of the protective cover 72 of the connecting mechanism 7. There are two housing mechanisms 6. One housing mechanism 6 is equipped with a mobile power supply 2 and a counterweight, while the other housing mechanism 6 is equipped with another mobile power supply 2, a control main board 31, and a pressure sensor. The pressure sensor detects the air pressure data inside the mask 1 through the first hole 611.

[0083] Both mobile power supplies 2 are used to supply power to the fan 5.

[0084] This embodiment improves the wind turbine's endurance by setting up two mobile power sources.

[0085] Example 3

[0086] The difference between this embodiment and Embodiment 1 is that in this embodiment, there are two fans 5; two mobile power supplies 2; two connecting mechanisms 7; and one filter box 9.

[0087] Please see Figures 8-9 As shown, two fans 5 are respectively mounted on the air inlet 11 and air outlet 12 via corresponding connecting mechanisms 7. Both fans 5 are located on the side of the corresponding one-way valve 4 furthest from the inner cavity of the mask 1. The fan 5 on the air inlet 11 is used to deliver air from outside the mask 1 to the inner cavity of the mask 1. The fan 5 on the air outlet 12 is used to deliver gas from inside the mask 1 to the outside of the mask 1. The connecting mechanism 7 mounted on the air inlet 11 is connected to the filter box 9.

[0088] Two portable power banks 2 are provided. Each portable power bank 2 corresponds to one fan 5, meaning the portable power bank 2 is adapted to supply power to the corresponding fan 5. In this embodiment, two housing mechanisms 6 are provided, and the portable power banks 2 are adapted to be placed within the corresponding housing mechanism 6. Specifically, one housing mechanism 6 houses one portable power bank 2 and a counterweight, while the other housing mechanism 6 houses a control motherboard 31 and another portable power bank 2. The control motherboard 31 is electrically connected to the portable power bank 2, the fan 5, the air pressure sensor, and the airflow sensor, respectively. Specifically, the control motherboard 31 is adapted to adjust the rotation speed of the two fans 5 based on the air pressure data inside the mask 1, thereby ensuring smooth breathing for the user. Furthermore, when the airflow at the air inlet 11 exceeds a threshold, the control motherboard 31 is adapted to control the fan 5 located at the air inlet 11 to decelerate, preventing excessive air discharge into the mask 1 from interfering with the user's normal breathing.

[0089] This embodiment uses a dual-fan structure to make breathing smoother and improve user comfort when wearing a smart air-supply breathing mask.
