Description

Technical Field

[0001] This invention relates to the field of heater technology, specifically to a face mask and air supply device. Background Technology

[0002] A heater is a device used for heating. Heaters directly convert electrical energy or other chemical energy into heat energy and transfer heat through radiation, convection, and other means, allowing users to move around in a suitable temperature environment.

[0003] Traditional convection heaters work by using heat energy to heat the air. The upper part of the convection heater casing has an air outlet, and the lower part has an air inlet. The air inlet draws in air and introduces it into the heater. When the heater is powered on, the heating element heats the air. The heated air rises and then flows out from the air outlet. This repeated circulation heats the air.

[0004] Traditional convection heaters deliver warm air into the room through vents. As a result, the air blown out is concentrated in the area directly opposite the vents, and the heat is also concentrated in that area. Consequently, the airflow speed and temperature are higher in the area directly opposite the vents, while the temperature is lower in other areas, which affects overall comfort. Summary of the Invention

[0068] like Figures 1 to 2As shown, in this embodiment, it further includes: an air guide 13, which is installed on the first air outlet 11 and the second air outlet 12, and is adapted to guide the side air outlets of the first air outlet 11 and the second air outlet 12.

In other embodiments, the air guide 13 is installed alone on the first air outlet 11, and is adapted to guide the air outlet of the first air outlet 11.

In other embodiments, the third through hole is formed separately on the first air outlet 11, extending inward along the surface of the first air outlet 11 and is adapted to guide airflow from the first air outlet 11 along the extension direction of the third through hole. In addition, in another embodiment, the third through hole is formed separately on the second air outlet 12, extending inward along the surface of the second air outlet 12 and is adapted to guide airflow from the second air outlet 12 along the extension direction of the third through hole. Specifically, the number of third through holes is not limited and can be set according to the requirements of the usage environment.

[0071] like Figures 1 to 2 As shown, in this embodiment, the main body is provided with a mounting part, which is disposed in a loop-shaped flow channel and is suitable for mounting lighting components.

[0072] Example 2

[0073] This embodiment provides an air supply device, including the air supply device provided in Embodiment 1. For example... Figures 1 to 5As shown, it also includes: a housing 2 and an air duct assembly 3. The housing 2 is mounted on the face mask, with a gap between the housing 2 and the face mask. An air inlet is located on the side of the gap closest to the face mask. A third air outlet 21 is provided on the outer wall of the housing 2, suitable for connecting to an external duct. The air duct assembly 3 is disposed within the housing 2 and includes: a first air duct component 31 and a second air duct component 32, which are stacked in a third-order direction. The first air duct component 31 has a first flow cavity, and the second air duct component 32 has a second flow cavity. The passage cavity is connected to the third air outlet 21 and the second air outlet 12 respectively. The second flow cavity is connected to the first air outlet 11, and the first flow cavity and the second flow cavity are connected. The air supply device has an air exchange state in which indoor air is driven by an external force to pass through the air inlet through the first flow cavity and blown out by the third air outlet 21; and an air supply state in which outside air is driven by an external force to be blown out through the air inlet through the second flow cavity to the first air outlet 11 and through the air inlet to the second air outlet 12. The air supply device switches between the air exchange state and the air supply state. In other embodiments, an air inlet is separately opened on the housing 2, and the air inlet is opened on the side of the housing 2 closer to the room. In addition, in another embodiment, an air inlet is separately opened on the main body 1, and the air inlet connects the main body 1, the housing 2 and the room. Specifically, the location of the air inlet is not limited, as long as it can ensure that indoor air can flow and be guided through the air inlet. In this embodiment, in the air supply state, the air is blown out from the first air outlet 11 and the second air outlet 12. When air is blown out from the first air outlet 11 and the second air outlet 12 simultaneously, the first air outlet 11 and the second air outlet 12 are simultaneously opened on the mask. In other embodiments, in the air supply state, the air is blown out from the first air outlet 11. When air is blown out from the first air outlet 11, only the first air outlet 11 is opened on the mask. In addition, in another embodiment, in the air supply state, the air is blown out from the second air outlet 12. When air is blown out from the second air outlet 12, only the second air outlet 12 is opened on the mask. Specifically, in the air supply state, the guiding position of the air is not limited, as long as it is ensured that it blows out along the air outlet.

[0074] In this air supply device, air is blown out from all the air outlets when the air is being supplied. The air blown out from all the air outlets is dispersed to different positions, thereby avoiding the air being concentrated. By blowing the air out from multiple air outlets, the airflow can be dispersed, thereby improving user comfort.

[0075] like Figures 1 to 5As shown, in this embodiment, the first air duct component 31 includes: a first drainage section, a second drainage section, and a first vortex section; the first drainage section forms a first drainage cavity, the second drainage section forms a second drainage cavity, and the first vortex section forms a first vortex cavity; the first drainage cavity, the first vortex cavity, and the second drainage cavity are interconnected; the first drainage cavity is connected to the third air outlet section 21, the second drainage cavity is connected to the second air outlet section 12, and the first air outlet section 11 is adapted to be connected to the driving component. The first drainage cavity is arranged along the length direction of the first air duct component 31 and parallel to the first direction; the second drainage cavity is arranged along the width direction of the first air duct component 31 and parallel to the second direction; the first vortex cavity connects the first drainage cavity and the second drainage cavity.

[0076] like Figures 1 to 5 As shown, in this embodiment, the second air duct component 32 includes: a third flow-inducing section and a second swirling section. The third flow-inducing section forms a third flow-inducing cavity, and the second swirling section forms a second swirling cavity. The third flow-inducing cavity is connected to the second swirling cavity and is connected to the first air outlet section 11. The second air outlet section 12 is adapted to be connected to the driving component. The third flow-inducing cavity is arranged along the length direction of the second air duct component 32 and parallel to the first direction.

[0077] like Figures 1 to 5 As shown, in this embodiment, the first swirling cavity and the second swirling cavity are connected.

[0078] like Figures 1 to 5 As shown, in this embodiment, the third drainage cavity is flared along the second direction and extends to the length end of the housing 2. The arrangement direction of the third drainage cavity allows air to be guided to the third air outlet 21 along the length direction of the housing 2.

[0079] like Figures 1 to 5 As shown, in this embodiment, it further includes: a wind turbine assembly, which is rotatably mounted on the housing 2 and sleeved on the air duct assembly 3. The wind turbine assembly includes: a driving component and a wind turbine component 4; the driving component is mounted on the housing 2; the wind turbine component 4 is rotatably mounted on the housing 2; the driving component is adapted to fit the wind turbine component 4, and the wind turbine component 4 is adapted to rotate relative to the housing 2 under the drive of the driving component. There are two sets of wind turbine assemblies, and the two sets of wind turbine assemblies rotate in different directions. That is, when the left wind turbine assembly rotates clockwise, the right wind turbine assembly rotates counterclockwise, thereby forming an air exchange state; when the left wind turbine assembly rotates counterclockwise, the right wind turbine assembly rotates clockwise, thereby forming an air supply state; the air exchange state and the air supply state can be adjusted by adjusting the rotation direction of the left and right wind turbine assemblies.

[0080] like Figures 1 to 5As shown, in this embodiment, the impeller component 4 includes: a first impeller 41 and a second impeller 42; the first impeller 41 is fixedly connected to the output shaft of the drive component; the second impeller 42 is fixedly connected to the output shaft of the drive component; the first impeller 41 and the second impeller 42 are stacked along the arrangement direction of the output shaft of the drive component, and the height of one of the first impeller 41 and the second impeller 42 matches the height of the first air duct component 31, and the height of the other one matches the height of the second air duct component 32. The outer diameters of the first impeller 41 and the second impeller 42 are different. By setting different outer diameters for the first impeller 41 and the second impeller 42, the airflow can be adjusted. The larger the outer diameter of the first impeller 41 and the second impeller 42, the larger the sweeping area of ​​the first impeller 41 and the second impeller 42, and the greater the airflow under the same driving speed. Conversely, the smaller the outer diameter of the first impeller 41 and the second impeller 42, the smaller the sweeping area of ​​the first impeller 41 and the second impeller 42, and the smaller the airflow under the same driving speed. That is, the outer diameter of the first impeller 41 and the second impeller 42 are positively correlated with the airflow. Therefore, when the first impeller 41 and the second impeller 42 are different sizes, the airflow between the upper and lower layers can be different under the drive of the same driving component. Thus, the airflow blown out from the first air duct component 31 and the second air duct component 32 is different, thereby meeting the airflow adjustment required in the air supply and ventilation states.

[0081] like Figures 1 to 2 As shown, it also includes: a heating element 5 and an air duct cover 6, wherein the heating element 5 is disposed between the housing 2 and the air duct assembly 3; the air duct cover 6 is disposed between the air duct assembly 3 and the face mask; the air duct cover 6 has a fourth through hole, and the second through hole is recessed inward along the surface of the air duct cover 6. The heating element 5 is adapted to heat the air flowing through it in the air supply state.

[0082] The air supply device connects the indoor air with the first vortex chamber and the second vortex chamber in the housing 2 through the air inlet. The first vortex chamber is connected to the first drainage chamber and the second drainage chamber. The second vortex chamber is connected to the third drainage chamber. The first drainage chamber is connected to the outdoor air through the third air outlet 21. The second drainage chamber is connected to the indoor air through the second air outlet. The third drainage chamber is connected to the indoor air through the first air outlet.

[0083] In the air supply state, the left-side impeller assembly, driven by the corresponding drive unit, rotates counterclockwise, while the right-side impeller assembly, driven by the corresponding drive unit, rotates clockwise. During this rotation, the first impeller guides air through the second drainage chamber to the second air outlet, thus blowing it into the room. The second impeller, also rotating, guides air through the third drainage chamber to the first air outlet, also blowing it into the room. When heating the air blown into the room is required, the heating element heats the air in the second and third drainage chambers, increasing the temperature of the air passing through the second and first air outlets. The heated air is then dispersed to all air outlets, allowing air to exit from different locations, reducing heat concentration and enabling simultaneous airflow from multiple areas. This reduces the temperature difference between concentrated air outlet areas and other areas, improving overall user comfort.

[0084] In the ventilation state, the left-side impeller assembly, driven by the corresponding drive unit, rotates the left-side impeller 4 clockwise, and the right-side impeller assembly, driven by the corresponding drive unit, rotates the right-side impeller 4 counterclockwise. During this rotation, the first impeller will drive the air through the first drainage chamber to the third air outlet 21. At the same time, the air generated by the second impeller during its rotation will be guided through the second vortex chamber to the first vortex chamber, and then through the first drainage chamber to the third air outlet 21. The air from the third air outlet 21 will be guided to the outside through the pipe, thereby exhausting the indoor air and realizing the ventilation operation.

[0085] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
