Description

Technical Field

[0001] This utility model belongs to the field of smart wearable devices, specifically relating to an air conditioning module and a smart wearable device. Background Technology

[0002] In addressing the challenges of high / low temperatures in outdoor work, air-conditioned clothing, as a smart wearable device integrating cooling / heating, portability, and human-centered design, is receiving increasing attention and promotion. Especially against the backdrop of rising global temperatures and increasingly harsh outdoor working environments, the application of air-conditioned clothing not only improves work efficiency but also significantly enhances the comfort and safety of workers. Currently, the market mainly offers gas-cooled and liquid-cooled air-conditioned clothing.

[0003] Gas-cooled clothing primarily utilizes vortex tubes and Peltier principles, employing semiconductor cooling components to generate heat or cool it. A small fan continuously draws outside air into the garment, promoting air circulation and dissipating heat generated by sweat evaporation. This type of clothing has a relatively simple structure and is commonly used by workers in industrial or construction sites.

[0004] However, the problem with existing air-conditioning suits is that their air inlets are mainly located on the top of the shell, while the air outlets are located on the sides. On the one hand, during operation, the side-mounted air inlets are easily blocked by foreign objects, which significantly reduces the cooling / heating effect of the suit. On the other hand, because the air inlets are on the top of the shell and the air outlets are on the sides, the air outlets can easily enter directly from the air inlets, creating dead air zones. Furthermore, if the internal airflow channel design is insufficient, airflow can easily run out without passing through the radiator, meaning that a lot of air is discharged from the air outlets without undergoing heat exchange, resulting in poor overall cooling / heating performance. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an air conditioning module and a smart wearable device that solve the problem of poor cooling / heating performance of existing air conditioning modules.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an air conditioning module, disposed in a smart wearable device, comprising: a housing, a controller and an air supply component housed within the housing, and a temperature regulating component at least partially housed within the housing; the air supply component is disposed above the temperature regulating component, wherein the housing comprises a detachably connected upper cover and a lower cover, the upper cover and the lower cover forming a cavity, and the temperature regulating component is fixedly disposed on the lower cover; the upper cover is provided with a radially arranged air inlet and an air outlet, the air outlet being disposed at a position closer to the center of the upper cover relative to the air inlet; the controller is connected to the temperature regulating component and the air supply component respectively, and is used to control the air supply component to exchange heat with the air entering from the air inlet and then flow out from the air outlet.

[0007] In one embodiment of this utility model, the temperature regulating component includes a fixedly mounted thermoelectric plate and a radiator. The thermoelectric plate is used to generate a set temperature, and the radiator is used to dissipate the temperature of the thermoelectric plate. The thermoelectric plate is fixed on the lower shell, and the radiator is mounted on the thermoelectric plate.

[0008] In one embodiment of this utility model, the radiator includes a fixedly arranged heat dissipation plate and a guide plate. A plurality of parallel guide plates are spaced apart on the heat dissipation plate to form an airflow channel for guiding air flow. The air inlet is arranged between the guide plates to directly communicate with the airflow channel.

[0009] In one embodiment of this utility model, the air supply assembly includes a fan disposed above a portion of the guide plate, the fan being fixedly connected to the heat sink; optionally, the height of the portion of the guide plate with the fan is less than the height of the other guide plates without the fan.

[0010] In one embodiment of this utility model, the length direction of the air inlet is arranged radially, and the length direction of the air outlet is arranged circumferentially; a plurality of air inlets are arranged circumferentially, and a plurality of air outlets are arranged radially and / or circumferentially.

[0011] In one embodiment of this utility model, the air supply assembly further includes an air guide ring, which is sleeved on the outside of the fan.

[0012] In one embodiment of this utility model, the lower shell includes a fixedly disposed base plate and a side plate. The side plate is wrapped around the base plate to form an open mouth. The side plate is provided with multiple ventilation openings, and the multiple ventilation openings of different sizes form a ventilation cluster. Optionally, multiple ventilation clusters are provided at equal intervals on the side plate.

[0013] As one embodiment of this utility model, the ventilation group includes first air holes, second air inlets and third air holes of different sizes. Multiple first air holes are provided, and the second air inlets and third air inlets are respectively provided on both sides of the multiple first air holes.

[0014] In one embodiment of this utility model, the air conditioning module further includes heat insulation cotton, which is disposed on the side of the base plate away from the top cover; and / or, the base plate is provided with a receiving hole capable of accommodating the thermoelectric plate of the temperature regulating component.

[0015] A second aspect of this utility model provides a smart wearable device, including the air conditioning module described in the first aspect of this utility model.

[0016] In summary, compared with the prior art, this utility model includes at least one of the following beneficial technical effects: The advantage of placing both the air inlet and outlet on the top cover is that, compared to placing the air inlet on the top cover, placing the air outlet on the side plate of the casing effectively solves the problems of easily forming air vortices and dead airflow (poor airflow and inability to dissipate heat). Furthermore, it avoids the problem of air flowing out of the outlet directly entering through the air inlet, resulting in a poor user experience. Attached Figure Description

[0031] It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of embodiments of this utility model. Furthermore, the descriptions of each embodiment in the following embodiments have their own emphasis; for parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0032] Please see Figure 1-6 The figure shows an air conditioning module installed on a smart wearable device, which may be, for example, clothing, hats, shoes, pants, or other wearable equipment. The air conditioning module includes a housing 100, a controller 200, and a thermoelectric plate 320, a radiator 310, and an air guide ring 410 housed within the housing 100.

[0033] The air conditioning module includes a housing 100, a controller 200, a temperature regulating component 300, and an air supply component 400. The controller 200 and the air supply component 400 are housed within a cavity of the housing 100, and the temperature regulating component 300 is at least partially housed within a cavity of the housing 100. The controller 200 is connected to both the temperature regulating component 300 and the air supply component 400, and is used to control the temperature regulating component 300 to output specific amounts of heat, and to control the air supply component 400 to deliver the air surrounding the temperature regulating component 300 out of the housing 100 after heat exchange.

[0034] The housing 100 includes a detachably connected upper cover 110 and a lower cover 120. The lower cover 120 has a base plate 121 and a side plate 122 disposed on the base plate. The base plate 121 and the side plate 122 form a hollow cavity opening towards the upper cover 110. The upper cover 110 and the lower cover 120 are matched to form a hollow housing 100. This invention does not limit the detachable fixing direction of the upper cover 110 and the lower cover 120; it can be a bolt connection, a snap-fit ​​connection, a tenon and mortise connection, etc. A snap-fit ​​connection is preferred, as this design effectively reduces manufacturing costs, increases installation efficiency, and facilitates mass production. The upper cover 110 includes a base 111, and an air inlet 112 and an air outlet 113 disposed on the base 111. In one embodiment, the air inlet 112 and the air outlet 113 are radially disposed on the base 111, with the air outlet 113 located closer to the center of the base 111 and the air inlet 112 located further away from the center of the base 111. Preferably, the air inlet 112 is arranged radially outside the air outlet 113.

[0035] The temperature control assembly 300 includes a heat sink 310 and a thermoelectric plate 320. The thermoelectric plate 320 and the heat sink 310 are arranged sequentially, with the thermoelectric plate 320 located near the lower housing 120 and the heat sink 310 located near the upper cover 110. One side of the thermoelectric plate 320 contacts and remains relatively fixed to the bottom plate 121 of the lower housing 120, while the other side contacts the heat sink 310. The thermoelectric plate 320 is a plate capable of both cooling and heating functions, and many technical solutions exist for it in the prior art. Preferably, the thermoelectric plate 320 is a semiconductor temperature control module, which can achieve bidirectional cooling / heating functions based on the Peltier effect.

[0036] The radiator 310 is fixedly mounted on the thermoelectric plate 320. Preferably, to better secure the radiator 310 and the thermoelectric plate 320, silicone is applied between them, achieving both fixation and improved heat transfer. The radiator 310 is used to transfer the temperature of the thermoelectric plate 320. Specifically, the radiator 310 has multiple spaced heat dissipation fins to evenly distribute the heat received from the thermoelectric plate 320 into the surrounding air, thus cooling / warming the surrounding air.

[0037] Please continue reading. Figure 1-6 An air supply assembly 400 is positioned above the temperature control assembly 300. The air supply assembly 400 includes an air guide ring 410 and a fan 420. The air guide ring 410 and fan 420 are positioned on the side of the radiator 310 away from the heat exchange plate 320. The fan 420 is positioned at the air outlet 113 of the upper cover 110. The air guide ring 410 is a ring-shaped structure, allowing the fan 420 to be housed within it. The fan 420 guides the air around the radiator 310 to disperse in a specific direction, and under the action of the air guide ring 410, guides the air around the radiator 310 to flow out from the air outlet 113 on the upper cover, thereby blowing out specific cool / hot air to regulate the air temperature. Preferably, the fan 420 is configured as a reverse-blade fan 420, which can change the airflow direction and airflow pattern by adjusting the blade angle or reversing the rotation direction of the fan 420. The advantage of choosing the 420 reverse blade fan is that it removes heat through negative pressure and transmits hot air a longer distance by exhausting it outwards without causing airflow vortices. This results in a more effective cooling effect compared to other similar designs, which is only different in terms of the direction of the fan's rotation.

[0038] Therefore, when the air conditioning module is needed to regulate the air temperature, the controller 200 controls the thermoelectric plate 320 to cool or heat, and controls the fan 420 to start. Then, the air is guided into the housing 100 through the ventilation hole 124 on the side plate 122 of the lower shell 120 and the air inlet 112 of the upper cover 110, and flows through the radiator 310. After heat exchange, the air flows out from the air outlet 113 of the upper cover 110.

[0039] It is understandable that the advantage of placing both the air inlet 112 and the air outlet 113 on the top cover 110 is that, compared to placing the air inlet 112 on the top cover 110, placing the air outlet 113 on the side panel 122 of the housing 100 can effectively solve the problems of easily forming air vortices and dead airflow (poor airflow and inability to dissipate heat). This also prevents air flowing out of the air outlet 113 from directly entering through the air inlet 112, thus avoiding a poor user experience.

[0040] Meanwhile, the advantage of setting the air inlet and air outlet 113 on the top cover 110 is that, compared with the solution of setting the air inlet 112 on the top cover 110 and the air outlet 113 on the side plate 122, it can not only allow more air to flow in and increase the air intake flow, but also effectively avoid local temperature differences, making the temperature inside the entire housing 100 more uniform, and making the temperature of the air blown out from the air outlet 113 more uniform.

[0041] Please continue reading. Figure 1-6The radiator 310 includes a fixed heat sink 311 and a guide plate 312. The heat sink 311 is provided with a plurality of spaced guide plates 312. The plurality of guide plates 312 are arranged in parallel or approximately parallel manner according to a set front-to-back spacing and left-to-right spacing, so that the gaps between the plurality of guide plates 312 form air flow channels, thereby guiding the air flow inside the housing 100.

[0042] The fan 420 is positioned near the axis of the housing 100. It is located above a portion of the guide plate 312 and is fixedly connected to the heat sink 311. The height of the guide plate 312 with the fan 420 is less than the other guide plates 312 without the fan 420. This arrangement aims to guide as much air as possible from the airflow channel to the bottom of the fan 420, where it is then driven to exit. This maximizes the airflow path within the heat sink 310's airflow channel, thereby improving heat exchange efficiency.

[0043] Please continue reading. Figure 1-6 Multiple air inlets 112 are provided, evenly arranged circumferentially. Each air inlet 112 has a roughly rectangular or waist-shaped structure, and its length direction is radially arranged. The air inlets 112 are configured to correspond to the airflow channel of the heat sink 310, i.e., the air inlets 112 are located within the gap between the two guide plates 312. Similarly, multiple air outlets 113 are also provided, arranged axially along their length direction. The air outlets 113 are located at positions corresponding to the fan 420, and the multiple air outlets 113 are evenly arranged circumferentially and / or radially. Figure 1 In this specific implementation, the air outlets 113 are arranged both axially and radially to better blow out the air.

[0044] It is understandable that setting the length direction of the air inlet 112 on the top cover 110 in the radial direction, and aligning the air inlet 112 with the air duct of the heat sink 310, has the advantage that this design can guide the air entering from the air inlet 112 through the airflow channel, thereby achieving better heat exchange. Similarly, setting the length direction of the air outlet 113 in the circumferential direction, and aligning it with the fan 420, has the advantage that when the fan 420 rotates around its axis, that is, when the blades move in the circumferential direction, it can better drive the air out, improving airflow efficiency.

[0045] Please continue reading. Figure 1-6The lower shell 120 includes a fixedly mounted base plate 121 and a side plate 122. The side plate 122 is fixedly mounted on the base plate 121 to form an opening with the base plate 121, creating a hollow cavity that mates with the upper cover 110. The base plate 121 has a receiving hole 123 for accommodating a thermoelectric plate 320, allowing the thermoelectric plate 320 to be snapped onto the base plate 121, thus reducing the overall height of the shell and improving usability. The controller 200 is fixedly mounted within the cavity of the shell, specifically on the base plate of the lower shell. The side plate 122 has multiple ventilation holes 124 for guiding air in. Preferably, the ventilation holes 124 can be of different sizes, forming a ventilation cluster with multiple ventilation clusters of different sizes spaced equally apart.

[0046] exist Figure 1 In this specific embodiment, four equally spaced ventilation clusters are provided on the side plate 122. Each ventilation cluster includes four ventilation holes 124, and the four ventilation holes 124 have three different sizes: a first ventilation hole, a second ventilation hole, and a third ventilation hole. The size of the first ventilation hole is larger than that of the second ventilation hole, and the size of the second ventilation hole is larger than that of the third ventilation hole. Two ventilation holes 124 with the largest size are provided side by side in the middle, and two ventilation holes 124 with different sizes are provided on both sides, thus forming a ventilation cluster. That is, the two first ventilation holes are spaced apart, and the second and third ventilation holes are respectively provided on both sides of the two first ventilation holes.

[0047] The dimensions of the first, second, and third air vents are designed to accommodate the effective airflow of their respective side panels 122. This design serves two purposes: firstly, by creating multiple vents of varying sizes to form a ventilation cluster, a more efficient airflow structure can be achieved, effectively supplementing the insufficient airflow from the top cover 110 and increasing the overall airflow of the air conditioning module; secondly, by using different sized vents within the ventilation cluster, the entry of dust and other debris into the housing 100 can be effectively reduced, improving the overall cleanliness of the air conditioning system.

[0048] Furthermore, this design offers several advantages. Firstly, by providing ventilation holes 124 on the side panel 122 of the lower cover and air inlets 112 on the upper cover 110, the dual air inlets 112 effectively improve air intake efficiency. Secondly, the ventilation holes on the side panel 122 align with the natural airflow direction on the side of the wearable device, thus reducing air resistance and further enhancing air intake efficiency.

[0049] Please continue reading. Figure 1-6The bottom plate 121 of the lower shell 120 is fixedly connected to the thermoelectric plate 320 on the side facing the upper shell. The air conditioning module also includes heat insulation cotton 500, which is disposed on the side of the bottom plate 121 of the lower shell 120 away from the upper shell to reduce the loss of heat generated by the thermoelectric plate 320.

[0050] Please continue reading. Figure 1 The air conditioning module also includes a cold plate 600, which is located below the insulation cotton 500 and fixedly connected to the bottom plate 121 of the lower shell 120 to cooperate with the radiator 310, "sandwiching" the insulation cotton 500 and the thermoelectric plate 320 in it, forming a sandwich structure to better achieve heat transfer.
