Description

Technical Field

[0001] This utility model relates to the field of integrated ceiling systems, specifically to a face mask and a heater. Background Technology

[0002] Existing heaters can be installed in conjunction with integrated ceilings, including a main unit that is attached and fixed above the keel support and a face shield that is suspended below the keel support. The hot air generated by the main unit is delivered to the indoor space through the face shield.

[0003] To improve the airflow efficiency of face masks, face masks with U-shaped vents have appeared on the market. The vents are arranged around the perimeter of the face mask, allowing hot air to diffuse in all directions. To form the U-shaped vents, the face mask needs to be designed with a central part, an outer ring around the central part, and a connecting rib between the outer edge of the central part and the inner edge of the outer ring. Since the connecting ribs are small and need to bear the weight of the central part and its functional components, they are prone to breakage under stress, which also increases the manufacturing difficulty and affects the user experience.

[0004] In addition, to ensure that the hot air generated by the main unit can be smoothly transferred to the mask, an air guide is usually installed on the mask. The inlet of the air guide is aligned and connected with the air outlet of the main unit, and the outlet of the air guide passes through the fan cover and is exposed in the indoor space, ensuring that the hot air can be smoothly delivered downwards. In addition to its function of airflow, the mask can also serve a decorative purpose by being removed and replaced. However, the presence of air guides on the mask increases the workload when replacing it, affecting the efficiency and convenience of replacement. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a face mask and a heater, with air vents opened in the center of each edge of the face mask, which not only facilitates processing and use, but also ensures that the airflow can effectively diffuse outward, thereby improving the user experience.

[0006] This invention is achieved through the following method: a face mask, including a mask body, with air vents arranged along its length in the middle of the edge of the mask body, allowing airflow to pass vertically through the air vents and be delivered downwards. The mask body is effectively fixed in the middle of each edge by means of air vents located between adjacent air vents, which facilitates large-scale processing, improves processing efficiency, ensures the structural strength of the mask body meets usage requirements, and enhances airflow diffusion efficiency and user experience by setting multiple air vents.

[0007] Preferably, the cover is integrally formed, and the air vent is a vertical through hole with a rectangular horizontal cross-section. The air vent is a vertical through hole without connecting ribs or other structural components, which effectively reduces wind resistance, improves airflow efficiency, facilitates processing, and ensures that the cover's structural strength meets usage requirements.

[0008] Preferably, the hood is rectangular, and the air vents include a short vent located in the middle of the width edge of the hood and a long vent located in the middle of the length edge of the hood. The hood has four air vents that are separated from each other and independently arranged, including two short vents and two long vents. This not only effectively improves airflow efficiency by increasing the number of air vents, but also ensures that the structural strength of the mask meets the usage requirements and improves the user experience.

[0009] Preferably, the length of the long opening is less than the distance between the short openings, and the length of the short openings is less than the distance between the long openings. A larger distance is set between the two ends of the long opening and the corresponding short opening, and between the two ends of the short opening and the corresponding long opening, effectively improving the connection strength between the periphery and the center of the cover, thereby meeting the load-bearing requirements of the center of the cover and its functional components.

[0010] Preferably, the bottom surface of the enclosure has an upwardly recessed light groove in the center, with a light panel at the opening of the groove and a light-emitting element inside. The light emitted by the light-emitting element passes through the light panel and is scattered outwards. By incorporating a light groove with a light-emitting element, the space in the center of the enclosure is effectively utilized, and the user experience is enhanced by adding functionality.

[0011] Preferably, the light trough is square, and the air vent is positioned along the edge of the light trough so that the air vent and the light trough are staggered. Positioning the air vent along the edge of the light trough effectively increases the area of ​​the light trough and also helps to eliminate the visual impact of the air vent by utilizing the edge of the light trough, thereby improving aesthetics.

[0012] Preferably, the edge of the cover is bent upwards to form a connecting strip. The connecting strip can be inserted and fixed to the triangular keel on the corresponding keel support, thereby facilitating the disassembly, maintenance, and replacement of the cover.

[0013] A heater includes a main unit with a face shield disposed below it. The main unit includes a housing and a fan and an air duct disposed within the housing. A heating module is installed within the air duct. The inlet of the air duct is connected to the fan, and the outlet is aligned with the air vent. Airflow generated by the fan passes through the air duct and the air vent and is then transported outward. The airflow generated by the fan flows through the heating module to form hot air, which is then transported outward through the air duct and the air vent. The face shield serves to shield the main unit, while the air vent allows the air duct outlet to be exposed, facilitating the outward transport of hot air.

[0014] Preferably, the outlet of the air duct is located on the bottom surface of the outer casing. An air guide is installed at the outlet, and the air guide has a constricted air passage that is wider at the top and narrower at the bottom. The wider opening of the air passage receives the airflow from the air duct and passes through the narrower opening to the corresponding air vent before being conveyed downwards. The air guide is installed at the bottom of the main unit and works in conjunction with the air vents on the face mask. This eliminates the need to disassemble and reassemble the air guide when changing the face mask and ensures that the hot air from the air duct can be guided by the air guide to pass through the air vents and be conveyed outwards, effectively reducing the loss of hot air along the way.

[0015] Preferably, the top edge of the air guide is provided with a connecting ear. The air guide is fitted onto the air duct outlet through a large opening. Fasteners pass through the connecting ear and spring in sequence and are then fixed to the outer shell. The height of the air guide can be adjusted by compressing the spring after it comes into contact with the mask, so that the small opening of the air guide is exposed downward through the air duct. The large opening fits onto the air duct outlet, and the two can be inserted and extended to maintain a fitted connection. This ensures that the small opening of the air guide can be flush with the air duct through extension and retraction, improving the aesthetics of the mask. It also ensures that the large opening of the air guide is always connected to the air duct outlet, preventing airflow from leaking out through the gap between the large opening and the outlet, thus improving the efficiency of hot air utilization. The spring accumulates a pre-tightening force to drive the air guide to return to its original position through compression, making the relative position between the air guide and the air duct outlet adjustable. It can also return to its original position by the spring after the external force is removed, making it convenient to use and eliminating the need for manual adjustment.

[0016] The beneficial effects of this invention are as follows: The mask's center and perimeter are effectively fixed by being positioned between adjacent air vents, facilitating large-scale manufacturing, improving processing efficiency, ensuring the mask's structural strength meets usage requirements, and enhancing airflow diffusion efficiency through multiple air vents, thus improving the user experience. Furthermore, the air guide is installed at the bottom of the main unit and works in conjunction with the air vents on the mask. This eliminates the need to disassemble the air guide when changing the mask and ensures that hot air from the duct is guided through the air vents and delivered outwards, effectively reducing heat loss along the way.

[0022] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1:

[0024] This embodiment provides a face mask.

[0025] like Figure 1 The mask shown comprises a mask body 1. Air vents are formed along the length of the mask body 1 at the center of its edges, allowing airflow to pass vertically through the vents and be delivered downwards. The mask body is effectively fixed between the center and periphery by means of vents located between adjacent areas. This facilitates large-scale manufacturing, improves processing efficiency, ensures the structural strength of the mask body 1 meets usage requirements, and enhances airflow diffusion efficiency and user experience through multiple vents.

[0026] In this embodiment, the cover 1 is integrally formed, and the air vent is a vertical through hole with a rectangular horizontal cross-section. Each air vent is a vertical through hole, and no connecting ribs are provided inside the air vent, which facilitates processing and also facilitates the passage and assembly of the air guide 12.

[0027] In this embodiment, the cover 1 is rectangular, and the air vent includes a short opening 2 located in the middle of the width edge of the cover 1 and a long opening 3 located in the middle of the length edge of the cover 1 (e.g., ...). Figure 2 (As shown). The long opening 3 and the short opening 2 are independent of each other and not connected, so that the adjacent short opening 2 and long opening 3 form a connecting area for connecting the periphery and the middle of the cover 1. This facilitates integrated processing and ensures that the weight of the middle of the cover 1 and its functional components can be transferred to the keel assembly through the periphery of the cover 1.

[0028] In this embodiment, the length of the long port 3 is less than the distance between the short ports 2, and the length of the short ports 2 is less than the distance between the long ports 3, ensuring that a large gap is reserved between the short ports 2 and the long ports 3, thus reserving space for setting up the connection area.

[0029] In this embodiment, a light groove 4 is formed by an upward indentation in the center of the bottom surface of the cover 1. A light panel 5 is provided at the opening of the light groove 4, and a light-emitting element is provided inside the light groove 4. The light emitted by the light-emitting element passes through the light panel 5 and is scattered outward. The light groove 4 is square, and the air vent is set along the edge of the light groove 4 so that the air vent and the light groove 4 are staggered, and the light panel 5 will not block the air vent, ensuring smooth flow of hot air.

[0030] In this embodiment, the edge of the cover 1 is bent upward to form a connecting strip 6. The cover 1 is fixed to the keel assembly by the connecting strip 6 located on its edge, ensuring that the mask is firmly installed and neatly spliced ​​with the adjacent decorative panel.

[0031] Example 2:

[0032] Compared to Embodiment 1, this embodiment provides a heater.

[0033] like Figure 3The heater shown consists of a main unit 7 and a face mask. The main unit 7 includes a housing 8 and a fan 9 and an air duct 10 disposed inside the housing 8. A heating module 11 is provided inside the air duct 10. The inlet of the air duct 10 is connected to the fan 9, and the outlet is aligned with the air outlet. The airflow generated by the fan 9 is delivered outward after passing through the air duct 10 and the air outlet.

[0034] In this embodiment, the outlet of the air duct 10 is located on the bottom surface of the outer casing 8. An air guide 12 is installed at the outlet. The air guide 12 has a constricted air passage that is wider at the top and narrower at the bottom. The wider opening of the air passage receives the airflow from the air duct 10 and passes through the narrower opening to the corresponding air outlet before being conveyed downwards. A connecting lug 14 is provided on the top edge of the air guide 12. The air guide 12 is fitted onto the outlet of the air duct 10 through the wider opening. Fasteners pass through the connecting lug 14 and the spring 13 in sequence and are then fixed to the outer casing 8 (e.g., ...). Figure 4 As shown, the air guide 12 can be adjusted in height by compression spring 13 after it comes into contact with the mask, so that the small opening of the air guide 12 is exposed downward through the air vent. The air guide 12 is installed at the bottom of the main unit 7 and works in conjunction with the air vent on the mask. This eliminates the need to remove the air guide 12 when changing the mask, and also ensures that the hot air from the air duct 10 can be guided by the air guide 12 to pass through the air vent and be delivered outward, effectively reducing the loss of hot air along the way.

[0035] In this embodiment, there are four air guides 12, which are arranged one by one with the four air vents on the mask to ensure that the airflow generated by the host 7 can be guided to the corresponding air vents and delivered downward through the four air guides 12.

[0036] The other structures and effects of the mask described in this embodiment are the same as those in Embodiment 1, and will not be repeated here.
