Description

Technical Field

[0001] This utility model relates to a head support device. Background Technology

[0002] As an indispensable sleep aid in daily life, the design and function of pillows directly affect people's sleep quality. Traditional pillows typically aim to provide support for the head and neck, and common materials include memory foam, latex, down, and fiber fillings. However, as people's demands for comfort and functionality continue to increase, pillows with special functions are gradually gaining attention. For example, pillows with ventilation functions can regulate head temperature through airflow, alleviating the stuffiness caused by prolonged contact and thus improving the user's sleep experience.

[0003] Currently, ventilated pillows on the market typically consist of two parts: a support body and a ventilation mechanism. The support body, as the core structure of the pillow, is usually rectangular or arched and has a support surface to support the weight of the head and neck. Air vents are also located on the support surface, serving as air outlets and working in conjunction with the ventilation mechanism. The ventilation mechanism controls airflow to deliver fresh air from the air vents to the support surface, thereby improving the pillow's breathability.

[0004] While these designs help alleviate the stuffiness caused by poor breathability of traditional pillows, some limitations remain. For example, some designs incorporate perforations within the support structure to concentrate airflow from the pillow. However, due to the softness of the pillow material, it tends to conform to the user's head and the back of their head during use. This conformation can partially obstruct the airflow, hindering air circulation and directly impacting ventilation. Utility Model Content

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] First Embodiment

[0036] See Figures 1-5 This embodiment provides a head support device on which a user can rest while sleeping. The head support device includes a support body 1 and a ventilation mechanism. The support body 1 has a shape that is higher at the front and back and lower in the middle. The front of the support body 1 is used to support the user's neck, and the middle part of the support body 1 is used to support the user's head. The support body 1 is made wholly or partially of a resilient material such as memory foam, which will not be described in detail here.

[0037] The support body 1 includes an upward-facing support surface 11 for supporting the user's head. In this embodiment, the support surface 11 includes a front area 111 for supporting the head and a rear area 112 near the front area. The front area 111 is provided with a first air outlet 211, and the rear area 112 is provided with a first air inlet 215.

[0038] The ventilation mechanism includes a ventilation component 26 and a first air guide mechanism 22. The ventilation component 26 is located within the support body 1. The first air guide mechanism 22 includes a first suction surface 221 and a first air outlet surface 222. The first air guide mechanism 22 guides airflow from the first suction surface 221 into the air and from the first air outlet surface 222 outwards. The first suction surface 221 faces the first air inlet 215, and the first air outlet surface 222 faces the ventilation component 26. The ventilation component 26 includes a first ventilation hole 261 that communicates at least partially with the first air outlet 211.

[0039] The ventilation component 26 further includes a second ventilation hole 262 and a ventilation cavity 264. The first air outlet surface 222 is disposed facing the second ventilation hole 262, and the second ventilation hole 262 communicates with the first ventilation hole 261 through the ventilation cavity 264. In this embodiment, the second ventilation hole 262 and the first ventilation hole 261 are disposed on the same plane.

[0040] The ventilation mechanism includes a first air guide channel and a first air guide mechanism 22. The first air guide channel is formed within the support body 1 and the ventilation component 26. The first air guide channel includes a first air outlet 211 and a first air inlet 215.

[0041] The first air guiding mechanism 22 is disposed within the first air guiding channel. The first air guiding mechanism 22 guides airflow sequentially through the first air inlet 215, the first suction surface 221, the first air outlet 222, the second ventilation hole 262, the ventilation cavity 264, and the first ventilation opening 261, and exits from the first air outlet 211. This airflow can cool the user's head. In this embodiment, the first air guiding channel is defined by the path of airflow between the first air inlet 215, the first suction surface 221, the first air outlet 222, the second ventilation hole 262, the ventilation cavity 264, the first ventilation opening 261, and the first air outlet 211.

[0042] In this embodiment, the ventilation mechanism further includes a temperature control mechanism 23, which is used to adjust the temperature of the first air guide channel. After the temperature of the first air guide channel decreases, the temperature of the airflow flowing out of the first air guide channel also decreases accordingly. Since the temperature control mechanism 23 cools the first air guide channel, the temperature of the blown airflow is more uniform and controllable. In some simpler alternatives, the temperature control mechanism 23 can also heat the first air guide channel. Therefore, the temperature control mechanism 23 is a cooling mechanism or a heating mechanism. In this embodiment, the ventilation component 26 is provided with a clearance hole 263, which corresponds to at least a portion of the temperature control mechanism 23.

[0043] The temperature control mechanism 23 includes an active temperature regulating element 231 and a first passive temperature conducting element 232. The active temperature regulating element 231 is connected to the first passive temperature conducting element 232. The first passive temperature conducting element 232 is at least partially located within the ventilation cavity 264 of the ventilation component 26, and at least partially corresponds to the clearance hole 263. The active temperature regulating element 231 is a semiconductor heating element, and the first passive temperature conducting element 232 is connected to the first temperature control side 2311 of the semiconductor heating element; wherein, the first temperature control side 2311 is a cooling side or a heating side. In this embodiment, the first temperature control side 2311 is a cooling side.

[0044] The temperature control mechanism 23 includes a second passive temperature conducting element 233, which is connected to the second temperature control side 2312 of the semiconductor heating and cooling sheet. The ventilation mechanism also includes a second air guide channel and a second air guide mechanism 25. The second passive temperature conducting element 233 is at least partially located in the second air guide channel, and the second air guide mechanism 25 is disposed in the second air guide channel. The second air guide channel includes a second air inlet 241 and a second air outlet, with the second air outlet located on the rear side of the support body 1.

[0045] At least a portion of the first passive heat-conducting element 232 is disposed within the first airflow channel. In this embodiment, the first passive heat-conducting element 232 includes a first base 2321 and a plurality of first heat dissipation fins 2322 disposed on the first base 2321. The first passive heat-conducting element 232 is entirely made of aluminum. In some simpler alternatives, a phase change element such as a heat pipe can also be disposed on the first passive heat-conducting element 232, which will not be elaborated here. The first passive heat-conducting element 232 can simply perform the function of passively conducting heat or cold. Those skilled in the art can make specific considerations based on factors such as cost and volume. In this embodiment, the plurality of first heat dissipation fins 2322 are disposed within the first airflow channel, and a channel is formed between two adjacent first heat dissipation fins 2322. Airflow can pass through the channels, carrying the cold air on the first heat dissipation fins 2322, thereby reducing the temperature of the airflow.

[0046] In this embodiment, the first base 2321 is T-shaped. The first base 2321 includes a transverse base 2323 and a longitudinal base 2324 connected to the middle of the transverse base 2323 and extending towards the rear of the support body 1. The first air guide mechanism 22 is disposed adjacent to the transverse base 2323 on the side near the longitudinal base 2324. A gap 2325 is provided between the longitudinal base 2324 and the rear of the support body 1, allowing airflow from the first air guide mechanism 22 to pass through. In this embodiment, the first base 2321 is T-shaped. The first heat dissipation fins 2322 are spaced apart along the left-right direction of the support body 1 on the lower side of the transverse base 2323. The upper side of the longitudinal base 2324 abuts against the cooling side of the semiconductor heat sink. Two openings are formed on both sides of the first base 2321, located on the rear side of the support body 1 and on the left and right sides of the support body 1. The support surface 11 is provided with two first air inlets 215 corresponding to the two empty spaces, and airflow can enter the first air guide channel from the first air inlets 215.

[0047] The first airflow channel extends downward from the first air inlet 215 of the support surface 11 to the second ventilation hole 262, then extends into the ventilation cavity 264, and finally extends upward from the first ventilation hole 261 to connect with the first air outlet 211. The first air outlet 211 corresponds to the front area of ​​the support surface 11, i.e., the user's neck area, and serves to dissipate heat. In this embodiment, the first heat dissipation fin 2322 is located inside the ventilation cavity 264, and the airflow passes through the first heat dissipation fin 2322 when passing through the ventilation cavity 264. The first passive temperature conducting element 232 extends and is disposed on the rear side of the support body 1 (i.e., the horizontal base 2323), and the airflow mechanism includes two first air intake fans.

[0048] The second passive temperature-conducting element 233 is connected to the heating side of the semiconductor heating element, and at least a portion of the second passive temperature-conducting element 233 is disposed within the second air duct. In this embodiment, the second passive temperature-conducting element 233 includes a second base 2331 and a plurality of second heat dissipation fins 2332 disposed on the second base 2331. The second passive temperature-conducting element 233 is entirely made of aluminum. In some simpler alternatives, a phase change element such as a heat pipe can also be disposed on the second passive temperature-conducting element 233, which will not be elaborated here. The second passive temperature-conducting element 233 can simply perform the function of passively conducting heat or cold.

[0049] The second airflow channel is defined by the path of airflow sequentially passing through the second air inlet 241, the second airflow guiding mechanism 25, the second passive heat-conducting element 233, and the second air outlet. In this embodiment, the second air inlet is located in the rear area, the second airflow channel is located entirely on the rear side of the support body 1, and the second airflow guiding mechanism 25 includes a second intake fan. Specifically, the semiconductor heat sink is sandwiched between the second base 2331 and the first base 2321, with the second base 2331 located at the top. Multiple second heat dissipation fins 2332 are arranged on the upper side of the second base 2331 extending along the front-rear direction of the support body 1. A channel is formed between adjacent second heat dissipation fins 2332. The second intake fan draws air from above, the airflow enters between the second heat dissipation fins 2332, and exhausts air from the rear. A baffle 2333 is provided in front of the second heat dissipation fins 2332 to prevent airflow from flowing out from the front and affecting the user's sleep.

[0050] In this embodiment, a temperature detection mechanism may also be provided. This mechanism is used to detect one or more of the ambient temperature, the temperature of the first air outlet 211, or the user's head temperature. It can also intelligently regulate the active temperature control element 231 via electronic programs to achieve intelligent temperature control. Specifically, the head support device includes at least one of the following temperature detection mechanisms: a first temperature sensor disposed on the support body for detecting the ambient temperature; a second temperature sensor disposed on the support surface for detecting the head temperature; and a third temperature sensor disposed near the first ventilation hole for detecting the temperature near the first ventilation outlet.

[0051] The head support device also includes a control box 27, which is detachably connected to the support body 1. The control box 27 includes a temperature display module for receiving the temperature from the temperature detection mechanism.

[0052] Second Embodiment

[0053] See Figures 6-9 The difference between this embodiment and the first embodiment is that: the first base 2321 is L-shaped, the longitudinal base 2324 is located on the right side of the support body 1, and a space capable of accommodating two first air intake fans is formed on the left side of the second base 2331. The two first air intake fans are arranged side by side in this space. The second ventilation hole 262 is provided on the side of the ventilation component 26, and the first ventilation hole 261 is provided on the upper surface of the ventilation component 26.

[0054] Correspondingly, the second air outlet is located on the right side of the support body 1, the second base 2331 is located above the longitudinal base 2324, and the semiconductor heating and cooling sheet is sandwiched between the two; wherein, the second air intake fan is arranged side by side with the first air intake fan.

[0055] Third Embodiment

[0056] See Figures 10-13 The difference between this embodiment and the first embodiment is that both the first passive temperature-conducting element 232 and the second passive temperature-conducting element 233 are located on the right side of the support body 1. In this embodiment, a third air intake fan 4 is provided on the right side of the support body 1, but the first passive temperature-conducting element 232 is not provided there. In this embodiment, the first air intake fan is a side-entry fan. The second ventilation hole 262 is located on the side of the ventilation component 26, and the first ventilation hole 261 is located on the upper surface of the ventilation component 26. The first air intake fan and the second air intake fan are arranged vertically.

[0057] Fourth embodiment

[0058] See Figure 14-15 The head support device also includes an air fiber layer 5. The support body 1 includes a pillow core made of memory foam or sponge, which serves as the support surface for the support body 1. The air fiber layer 52 is 3D, 4D, or 5D air fiber, made of ultra-fine polyethylene. Ultra-high molecular weight polyethylene fiber is spun from ultra-high molecular weight polyethylene (UHMWPE, a high-density polyethylene with a molecular weight higher than 1 million). The air fiber has a three-dimensional interwoven mesh structure, providing good support while ensuring overall softness and comfort. The mesh-like gaps inside the material allow air to circulate freely, effectively wicking away moisture and dissipating heat, making it suitable for use in summer or humid environments.

[0059] The ventilation mechanism guides airflow from the first air inlet 215 into the first air outlet 211, with the air fiber layer 5 forming the first air outlet 211. When the air fiber layer 5 forms the first air outlet 211, the user's head rests on the air fiber layer 5, and the first air outlet 211 is not completely blocked by the head, allowing airflow to seep out from the surface of the air fiber layer 5. In particular, the mesh-like pores inside the air fiber layer 5 allow air to circulate freely. The support body functions to guide and direct the outflow of air, and the air fiber layer 5 prevents the first air outlet 211 from being completely blocked, ensuring that the ventilation mechanism can continuously and efficiently introduce airflow from the first air inlet 215 and allow it to seep out from the surface of the air fiber layer 5, thereby achieving a uniform and stable ventilation effect.

[0060] In this embodiment, the front area of ​​the support surface includes a recessed ventilation area 113, with the first ventilation hole 261 disposed on the ventilation area 113, and the air fiber layer 5 covering the ventilation area 113. The recessed design of the ventilation area 113 facilitates precise positioning of the air fiber layer 5, ensuring its stable coverage. This design prevents the air fiber layer 5 from shifting due to head movement or external forces during use, thus ensuring the stability of the airflow path and improving ventilation. The connection methods between the ventilation area 113 and the air fiber layer 5 include, but are not limited to, Velcro, adhesive, magnetic links, snap-fit, and interference fits, providing diverse fixing methods. Users can easily disassemble and replace the air fiber layer 5 as needed, facilitating cleaning and maintenance and reducing the difficulty of daily operation.

[0061] In this embodiment, when the air fiber layer 5 is placed over the ventilation area 113, the outer side of the air fiber layer 5 is flush with the front area. This flush design is not only aesthetically pleasing, but also provides a flatter support surface when the head is resting on the pillow, avoiding the discomfort caused by height differences in traditional structures and further improving the comfort of the pillow.

[0062] In this embodiment, multiple first ventilation holes 261 are spaced apart within the ventilation area 113. The recessed ventilation area 113 concentrates the first ventilation holes 261, focusing the ventilation function on the head contact area, ensuring effective utilization of airflow, and avoiding energy waste caused by airflow being dispersed to irrelevant areas. This design improves the efficiency of the ventilation mechanism, making it more targeted and practical.

[0063] In this embodiment, the air fiber layer 5 forms a plurality of first air outlets 211, each corresponding to a first ventilation hole 261. The air fiber layer 5 includes first air outlets 211 corresponding to the first ventilation holes 261, ensuring that airflow can directly exit from the first ventilation holes 261 through these first air outlets 211, reducing airflow resistance as it passes through the fiber layer. This smoother airflow effectively improves ventilation efficiency and significantly enhances the pillow's heat dissipation and breathability.

[0064] In this embodiment, the ventilation mechanism includes a first air guide mechanism 22 and a first air guide channel similar to those in the first, second, and third embodiments. The first air guide channel is disposed within the support body 1 and is connected to the first air outlet 211. The first air guide mechanism 22 is used to guide airflow out of the first air outlet 211. In this embodiment, the first air guide mechanism 22 can be a fan, air pump, or other structure, which will not be described in detail here. The entire air fiber layer 5 allows airflow to pass through. The first air outlet 211 can guide and accelerate airflow through, but if the first air outlet 211 is partially blocked by the head, airflow can still pass through the air fiber layer 5.

[0065] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
