When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the invention.
[0036] Depend on Figure 1 and Figure 2 As shown in the figure, the basic embodiment of the present invention, which demonstrates the main concept, discloses a head-mounted device, including a main body and a face mask 6 disposed on the face-facing end of the main body; the main body includes a housing 1 and a heating element disposed within the housing 1; the face mask 6 is provided with an air inlet channel, the face-facing end of the housing 1 is provided with an air inlet hole unit corresponding to and communicating with the air inlet channel, and the top and / or the side away from the face of the housing 1 is provided with an air outlet hole unit 5; a partition 16 is provided in the inner cavity defined by the housing 1, the partition 16 dividing the inner cavity into an independent air inlet cavity 11 and an air outlet cavity 12; a fan 7 is provided on the partition 16, the air inlet end and the air inlet hole unit of the fan 7 are both connected to the air inlet cavity 11, and the air outlet end and the air outlet hole unit 5 of the fan 7 are both connected to the air outlet cavity 12; the fan 7 is used to guide external air through the air inlet channel and the air inlet hole unit into the air inlet cavity 11, exchange heat with the heating element, and then enter the air outlet cavity 12, and be discharged to the outside through the air outlet hole unit 5.
[0037] Fan 7 provides directional propulsion for accelerated airflow. During heat dissipation, external cold air first passes through the air intake channel on the mask 6, where it dissipates heat and dehumidifies the mask 6, indirectly reducing the user's facial temperature and humidity at the point where the mask touches the face, thus improving the user experience. Then, the cold air enters the air intake cavity 11 through the air intake unit, dissipating heat from the internal heat-generating components and preventing damage due to overheating, thereby extending their lifespan. Finally, the air is exhausted to the outside, completing one heat dissipation cycle. Furthermore, airflow occurs only at the fan 7 mounting location in the air intake cavity 11 and the air outlet cavity 12; the remaining areas remain sealed. This maximizes the operating efficiency of fan 7, further improving heat dissipation. Moreover, the air outlet unit 5 is located on the top of the enclosure 1 and / or on the side facing away from the face, preventing the direction of hot airflow from interfering with facial comfort or the heat dissipation of the mask 6, further enhancing the user experience and ensuring effective heat dissipation.
[0038] In one specific embodiment, the encapsulation shell 1 has two lens mounting holes spaced apart on the side facing the face, and three air inlet units are provided (the number of air inlet units can be adjusted as needed), namely a first air inlet unit 2, a second air inlet unit 3, and a third air inlet unit 4; the first air inlet unit 2 is located above the lens mounting holes, and the second air inlet units 3 and 4 are symmetrically arranged, with the two lens mounting holes located between the second air inlet units 3 and 4. Correspondingly, the face mask 6 has three air inlet channels (the number of air inlet channels can be adjusted as needed, corresponding one-to-one with the air inlet units), namely a first air inlet channel, a second air inlet channel, and a third air inlet channel; the first air inlet channel is connected to the first air inlet unit, the second air inlet channel is connected to the second air inlet unit, and the third air inlet channel is connected to the third air inlet unit. Thus, the technical solution of providing air inlet units and air inlet channels in multiple areas can improve heat dissipation.
[0039] In another specific embodiment, by Figure 3 and Figure 4 As shown, the encapsulation shell 1 includes a front shell 13, a rear shell 14, and a middle shell 15 that are fastened together, defining an inner cavity. The middle shell 15 includes a connected top plate and two headband connecting arms, which are located on the left and right sides of the rear shell 14. The top of the partition 16 abuts against the top plate of the middle shell 15; the front shell 13 has a U-shaped baffle 132 extending towards the rear shell 14 on the side facing the face, and the U-shaped baffle 132 abuts against the partition 16; and the U-shaped baffle 132, the front shell 13 inside the U-shaped baffle 132 (i.e., a part of the front shell 13 defined by the U-shaped baffle 132), the partition 16, and the middle shell 15 together enclose an air outlet cavity 12, with the remaining inner cavity being an air inlet cavity 11. In this embodiment, the space of the air inlet cavity 11 is larger than that of the air outlet cavity 12, and the number of air outlet units 5 is greater than that of the air inlet units; thus, the air flow speed at the air outlet units 5 can be increased, further improving the heat dissipation effect.
[0040] Preferably, the partition 16 is provided with a U-shaped sealing gasket 17 that is adapted to the U-shaped baffle 132. This improves the sealing performance of the air outlet cavity 12, prevents airflow mixing between the air outlet cavity 12 and the air inlet cavity 11 at the contact point, ensures normal airflow, and further ensures the heat dissipation effect.
[0041] In another specific embodiment, the top of the front shell 13 is provided with a first notch 131, and the top of the rear shell 14 is provided with a second notch 141; the middle shell 15 is provided with a first extension 151 extending downward into the first notch 131 and a second extension 152 extending downward into the second notch 141; the second extension is provided with an air inlet unit (i.e., the first air inlet unit 2); the air outlet unit 5 is disposed on the first extension 151. Preferably, the middle shell 15 is provided with a partition 153 located between the first extension 151 and the second extension 152, and the partition 16 abuts against the partition 153. The space defined by the partition 153 and the first extension 151 is part of the air outlet cavity 12; the space defined by the partition 153 and the second extension 152 is part of the air inlet cavity 11. This arrangement not only ensures heat dissipation but also improves aesthetics.
[0042] In another specific embodiment, by Figure 5 and Figure 6 As shown, the mask 6 includes a mask bracket 61 and a mask body 62; the mask bracket 61 includes an end portion 613 and a peripheral portion 612 disposed on the outer edge of the end portion 613 and extending toward the mask body 62. The end portion 613 and the peripheral portion 612 define an installation space. The end of the mask body 62 facing away from the face is located within the installation space, thus ensuring the reliability of the installation of the mask bracket 61 and the mask body 62. Preferably, the top and left and right sides of the end of the mask body 62 facing away from the face are provided with ventilation structures 621. Each ventilation structure 621, the inner wall of the periphery 612 of the mask support 61, and the inner wall of the end 613 of the mask support 61 together form a ventilation cavity 63 communicating with the outside. The end 613 of the mask support 61 is provided with three ventilation hole units 611 that correspond one-to-one with the ventilation cavity 63. The ventilation cavity 63 and the corresponding ventilation hole units 611 constitute an air intake channel. This arrangement can further improve the heat dissipation and dehumidification effect of the mask body 62. In addition, the position of the ventilation structure 621 can avoid discomfort to the user's face caused by fast-flowing airflow.
[0043] More preferably, each vent unit 611 includes a plurality of vent holes, and each air inlet unit includes a plurality of air inlets; in the vent unit 611 and air inlet unit at the same location, the air inlets and vent holes are aligned one by one; this ensures effective air circulation.
[0044] Preferably, the mask body 62 includes a mounting portion 622 and a face-contact portion 623 connected to each other; the mounting portion 622 is installed within the mounting space, and the face-contact portion 623 extends beyond the mask bracket 61 (attached with an adhesive layer); the outer peripheral surface of the mounting portion 622 is in contact with the inner wall of the periphery 612 of the mask bracket 61 (also attached with an adhesive layer); the end face of the mounting portion 622 abuts against the inner wall of the end 613 of the mask bracket 61 (also attached with an adhesive layer). Preferably, a stepped surface 624 is formed between the outer peripheral surface of the mounting portion 622 and the outer peripheral surface of the face-contact portion 623, and the end face of the periphery 612 of the mask bracket 61 abuts against the stepped surface 624 (also attached with an adhesive layer). This arrangement avoids air mixing at the contact and abutment points during airflow, improving the effectiveness of directional airflow. In a further preferred embodiment, the outer peripheral surface of the periphery 612 of the mask support 61 is flush with the outer peripheral surface of the face-fitting part 623, with no height difference; thus, the mask 6 appears to be a single component, further improving its aesthetics.
[0045] The ventilation structure 621 can be one of three types: a groove-shaped structure, a perforated structure, or a hollow structure; or, the ventilation structure 621 can be a combination of two or three of these three types. The ventilation structure 621 shown in the figure is a groove-shaped structure. Each ventilation structure 621 includes multiple first ventilation sections spaced apart on the outer periphery of the face-contact portion 623 away from the face, and multiple second ventilation sections disposed on the mounting portion 622 and correspondingly connected to the first ventilation sections. The second ventilation sections and the mask bracket 61 form a ventilation cavity 63, with the first ventilation sections exposed, serving as the entrance to the ventilation cavity 63.
[0046] Preferably, the mask body 62 includes an outer layer and an inner layer; the outer layer is made of a one-way moisture-wicking fabric (quick-drying fabric), and the inner layer is made of a flexible material (foam, silicone, etc.). This further improves the heat dissipation and dehumidification effect. The ventilation structure 621 can be located on the inner layer, or it can be located on both the inner and outer layers.
[0047] In some embodiments, the end 613 of the mask bracket 61, facing away from the mask body 62, has a detachable connection structure for easy detachable connection with the main body. This design facilitates the replacement and cleaning of the mask 6, further improving the user experience. The detachable connection structure can be a latch, slot, magnetic fastener, or Velcro, etc.
[0048] The following is based on Figure 2 The airflow path shown briefly illustrates the heat dissipation process:
[0049] When the fan 7 rotates, the cold air from outside first enters the ventilation cavity 63 through the ventilation structure 621 on the mask body 62, and then enters the air intake cavity 11 through the ventilation hole unit 611 on the mask bracket 61, the air intake hole unit on the rear shell 14 and the second extension 152 in sequence. Then, driven by the fan blades of the fan 7, it enters the air outlet cavity 12, and is then discharged to the outside through the air outlet hole unit 5 on the first extension 151, completing one heat dissipation cycle.
[0050] The various embodiments in this specification are described in a progressive or parallel manner. Each embodiment focuses on the differences from other embodiments, and the same or similar parts between the various embodiments can be referred to each other.
[0051] In summary, this invention can dissipate heat from both the heat-generating components and the mask, with excellent heat dissipation effect, thus improving the lifespan of the head-mounted device and the user experience.
[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
