Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] Please refer to Figure 1-Figure 8 The present application provides a temperature control device 10, including a housing 1, a temperature control component 2, an energy radiator 23 and a first fan 3. The housing 1 is provided with a first air inlet 11; the temperature control component 2 is arranged in the housing 1, and the energy radiator 23 is arranged in the housing and connected to the temperature control component 2; the first fan 3 is arranged in the housing 1, and the energy radiator 23 is located between the first fan 3 and the first air inlet 11. When the first fan 3 is working, air can be sucked into the housing 1 through the first air inlet 11 and contact the energy radiator 23 to be cooled or heated. It can be understood that the connection between the energy radiator 23 and the temperature control component 2 can be a direct connection or an indirect connection to form heat or cold conduction between the energy radiator 23 and the temperature control component 2.

[0045] Compared with the traditional method of blowing air to the energy radiator 23 at high speed through a fan, in the present embodiment, the air is sucked into the shell 1 by suction. When the first fan 3 starts working, the pressure in the shell 1 decreases, and the outside air is sucked in from the first air inlet 11. Since the energy radiator 23 in the present application is arranged between the first fan 3 and the first air inlet 11, when the air is sucked in from the first air inlet 11, compared with the high-speed flow through the energy radiator 23 in the traditional method, the present embodiment does not provide a blowing force between the first air inlet 11 and the energy radiator 23. Therefore, the air in the present embodiment can flow to the energy radiator 23 relatively slowly, so that it can fully contact the energy radiator 23, further allowing the air to be cooled or heated more evenly before flowing to the first fan 3, and then blown out of the shell 1 after being accelerated by the first fan 3, so that the temperature of the cooled or heated air blown out of the shell 1 is more uniform, thereby improving the user experience. It is understandable that, in one embodiment, the energy radiator 23 may be a cold radiator. In this embodiment, when the first fan 3 starts working, the outside air is sucked in from the first air inlet 11 and flows through the cold radiator. After being fully in contact with the cold radiator, it is blown out of the shell 1 through the first fan 3. In summary, the air blown out in this embodiment is fully in contact with the cold radiator in the shell 1 and cooled, so it can be blown out of the shell 1 more evenly. In another embodiment, the energy radiator 23 may be a heat radiator. In this embodiment, when the first fan 3 starts working, the outside air is sucked in from the first air inlet 11 and flows through the heat radiator. After being fully in contact with the heat radiator, it is blown out of the shell 1 through the first fan 3. In summary, the air blown out in this embodiment is fully in contact with the heat radiator in the shell 1 and heated, so it can be blown out of the shell 1 more evenly.

[0046] In some embodiments, see Figure 2 and Figure 6 The temperature control device 10 further includes a partition 4, which is disposed in the housing 1 to separate the cavity in the housing 1 into a first air duct 12. The first fan 3 and the energy emitter 23 are disposed in the first air duct 12. The first air inlet 11 is connected to the first air duct 12. When the first fan 3 is working, air can be sucked into the first air duct 12 through the first air inlet 11. In this embodiment, after the air is sucked into the first air duct 12 from the first air inlet 11, compared with the high-speed flow through the energy emitter 23 in the traditional method, this embodiment does not provide a blowing force between the first air inlet 11 and the energy emitter 23, so that the air in this embodiment can flow to the energy emitter 23 relatively slowly, so that the air can fully contact the energy emitter 23, and further enable the air to be cooled or heated more evenly before flowing to the first fan 3, and then blown out of the first air duct 12 after being accelerated by the first fan 3.

[0047] In another embodiment, the energy emitter 23 is connected to the cold end 21 of the temperature regulating component 2, the temperature regulating device 10 also includes a second fan 6, the second fan 6 is, for example, a centrifugal fan, the partition 4 also separates the cavity in the shell into a second air duct 13, the second air duct 13 is spaced apart from the first air duct 12, the portable temperature regulating device 10 also includes a second fan 6 and a radiator 24, the second fan 6 and the radiator 24 are arranged in the second air duct 13, the radiator 24 is connected to the hot end 22 of the temperature regulating component 2, the shell 1 is provided with a second air inlet 18, the second air inlet 18 is connected to the second air duct 13, the hot end 22 of the temperature regulating component 2 faces the second air duct 13, the radiator 24 is accommodated in the second air duct 13, the second fan 6 is located between the second air inlet 18 and the radiator 24, when the second fan 6 is working, the second fan 6 can blow the air coming in from the second air inlet 18 to the radiator 24. In this embodiment, the second air duct 13 adopts a blowing method, and the second fan 6 is arranged between the radiator 24 and the second air inlet 18. When the air enters from the second air inlet 18, the second fan 6 blows the air toward the radiator 24, so that the air passes through the radiator 24 at a high speed, thereby taking the heat in the second air duct 13 out of the housing 1, and avoiding the excessive heat in the second air duct 13 affecting the temperature adjustment effect of the thermostat 2, such as the cooling effect at the cold end 21 of the thermostat 2. In this embodiment, the heat in the second air duct 13 is quickly blown out of the housing 1, so that the temperature adjustment effect of the thermostat 2 is better.

[0048] In some embodiments, the shell 1 includes a connecting section 14 and an extension section 15 arranged at both ends of the connecting section 14. The connecting section 14 and the two extension sections 15 enclose a wearing space 5. The temperature regulating component 1, the energy radiator 23 and the first fan 3 are arranged in the connecting section 14 and / or the two extension sections 15. In combination with the foregoing, on the other hand, it can be understood that the position of the first air duct 12 can be flexibly set. For a wearable fan, such as a neck-hanging fan, the first air duct 12 can be set at a position facing the neck or cheek. For example, the shell 1 may include a connecting section 14 and an extension section 15 arranged at both ends of the connecting section 14. The connecting section 14 and the extension section 15 are arranged to form a wearing space 5. The partition 4 includes multiple parts, two of which are respectively arranged at the extension section 15 to divide the cavity in the extension section 15 into a first air duct 12 and a second air duct 13. The first air duct 12 is close to the wearing space 5, and the second air duct 13 is away from the wearing space 5, so that the air cooled or heated by the energy emitter 23 can be blown to the wearing space 5. The wearing space 5 can be worn on the user's wrist, neck or even leg, etc.; for a handheld fan, the first air duct 12 can be set on the side facing the user. For example, the shell 1 includes a main body and a handheld section connected to the main body, and the partition 4 is arranged at the main body to divide the cavity of the main body into the first air duct 12 and the second air duct 13. The user can hold the hand-held section and point the main body toward a place where air needs to be blown, so that the cooling or heating of the energy emitter 23 can be blown to the user.

[0049] In some embodiments, the first air duct 12 includes a first air guiding channel 121, a second air guiding channel 122, a third air guiding channel 123 and an air outlet channel 1211. Figure 2 In the present embodiment, an air outlet 16 is further provided on the shell 1, and the first air duct 12 connects the first air inlet 11 and the air outlet 16. The first fan 3 is, for example, a centrifugal fan. A first air guide portion 41 is provided on the side of the partition 4 facing the first air duct 12. The first air guide portion 41 is provided around the outer side of the first fan 3 to form a first air guide channel 121. The air cooled or heated by the energy dissipator 23 can flow out of the air outlet 16 through the first air guide channel 121. With such a configuration, the cold air or hot air blowing toward the first fan 3 can be guided to ensure that it can flow out of the air outlet 16. On the other hand, the presence of the first air guide portion 41 can change the flow direction of the air, so that the air outlet 16 can be set according to the needs of the user, so as to reasonably and effectively utilize the space in the shell 1. For more details, please refer to Figure 4 and Figure 6 In the present application, a second air guide portion 42 and a partition portion 44 are also provided on the side of the partition member 4 facing the first air duct 12. The partition portion 44 is connected to the first air guide portion 41, and a second air guide channel 122 is formed between the partition portion 44 and the second air guide portion 42. The partition portion 44 is also provided with a vent 441 to connect the first air guide channel 121 and the second air guide channel 122, so that the air cooled or heated by the energy emitter 23 can enter the first air guide channel 121 through the second air guide channel 122. With such a configuration, the outside air can directly enter the first air guide channel 121 through the second air guide channel 122 after the energy emitter 23 is cooled or heated, avoiding overflow. On the other hand, the compactness of the structure in the housing 1 is improved, and the space utilization rate in the housing 1 is improved on the basis of greatly ensuring the effective realization of the temperature control effect. The cooled or heated air flows to the first air guide channel 121 through the second air guide channel 122 and flows to the air inlet side of the first fan 3 , so that the cooled or heated air can be effectively blown out of the air outlet 16 of the shell 1 through the air outlet side of the first fan 3 .

[0050] For further information, please refer to Figure 4 and Figure 6The partition 4 is also provided with a third air guide portion 43, one end of which is connected to the second air guide portion 42, and the other end of which is obliquely extended toward the partition 44 and / or the first air guide portion 41 to form a third air guide channel 123, and the third air guide channel 123 is connected to the second air guide channel 122, so that the air cooled or heated by the energy emitter 23 can enter the second air guide channel 122 through the third air guide channel 123. In this embodiment, the oblique extension of the third air guide portion 43 can guide the flow direction of the cooled or heated air, thereby guiding the cooled or heated air to the second air guide channel 122, and making full use of the space in the housing 1.

[0051] For further information, see Figure 2 , a fourth air guide portion 17 is also provided on the side of the shell 1 facing the first air duct 12, and the fourth air guide portion 17 is located on the side of the energy emitter 23 close to the air outlet 16, so as to separate the cavity in the shell 1 to form an air outlet channel 1211, and the air outlet channel 1211 is respectively connected to the first air guide channel 121 and the air outlet 16. In this embodiment, the cooled or heated air entering the first air guide channel 121 is blown out of the shell 1 from the air outlet 16 along the air outlet channel 1211 under the action of the first air guide portion 41, the second air guide portion 42, the third air guide portion 43 and the fourth air guide portion 17. The air outlet channel 1211 in this embodiment can be located at the top of the energy emitter 23, which not only makes full use of the space in the shell 1, but also because the air outlet channel 1211 is close to the energy emitter 23, there is a situation where the energy emitter 23 cools or heats the air in the air outlet channel 1211 again, thereby improving the temperature adjustment effect. It can be understood that the fourth air guide portion 17 can be a conductive material in one embodiment, so as to facilitate the temperature adjustment again.

[0052] See also Figure 2 In the present application, the air outlets 16 include multiple ones, and the temperature control device 10 further includes at least one diverter 7, which is arranged in the air outlet channel 1211 to divert the air to each air outlet 16 through the air outlet channel 1211 at the outlet of the first air guide channel 121, and the cooled or heated air can be blown out of the housing 1 through the multiple air outlets 16. Such an arrangement makes the cold air or hot air flowing out of the multiple air outlets 16 uniform and delicate, thereby improving the user's comfort.

[0053] For further information, see Figure 7-Figure 8The energy radiator 23 includes an energy radiating bottom plate 231 and a plurality of energy radiating sheets 232. The plurality of energy radiating sheets 232 are arranged on the side of the energy radiating bottom plate 231 away from the cold end 21 of the temperature regulating member 2 and are accommodated in the first air duct 12. The energy radiating bottom plate 231 is arranged at the cold end 21 of the temperature regulating member 2 and is at least partially exposed to at least one of the first air guide channel 121 and the air outlet channel 1211. In this embodiment, the energy radiating bottom plate 231 is arranged at the cold end 21 of the temperature regulating member 2 and is exposed to the first air guide channel 121 and the air outlet channel 1211 to re-cool the air flowing along the air flow path until the air flows out of the air outlet 16 to form cold air.

[0054] Similarly, in the second air duct 13, the radiator 24 includes a heat dissipation base plate 241 and a heat dissipation fin 242. The heat dissipation fin 242 is arranged on a side of the heat dissipation base plate 241 away from the hot end 22 and is accommodated in the second air duct 13. The heat dissipation base plate 241 is arranged at the hot end 22 of the temperature adjustment element 2 and can be at least partially exposed in the second air duct 13. In this way, when the second fan 6 starts to work, the heat of the heat dissipation base plate 241 can be taken out of the second air duct 13 by flowing through the second air duct 13, so as to improve the cooling effect of the temperature adjustment device 10.

[0055] Furthermore, a fifth air guide portion 45 is provided on the side of the partition 4 facing the second air duct 13, and the fourth air guide portion 45 is located on the outside of the second fan 6 to form a heat dissipation channel 131 in the second air duct 13, so that the wind force of the second fan 6 is blown toward the radiator 24, so that the flowing air quickly takes away the heat in the second air duct 13, and is further blown out from the heat dissipation port 132 opened in the second air duct 13.
