[0042] Please see Figures 1 to 3In some embodiments, this utility model provides a portable air conditioner, including a housing 100, a thermoelectric cooler 200, a first fan 310, and a battery 400. The housing 100 has a cavity, and its outer wall has a first air inlet 110 and a first air outlet 120 connecting the interior of the cavity to the outside. A first air duct 300 for gas flow is disposed between the first air inlet 110 and the first air outlet 120. The thermoelectric cooler 200 is assembled inside the housing 100, with its cold or hot surface connected to the first air duct 300 to regulate the gas temperature within the first air duct 300. The first fan 310 is assembled inside the first air duct 300, and its airflow direction is towards the first air outlet 120. The battery 400 is assembled inside the housing 100 and connected to the thermoelectric cooler 200 and the first fan 310 respectively via conductive components. In operation, the operator activates battery 400, which powers both the thermoelectric cooler 200 and the first fan 310. The temperature of the cold side of the thermoelectric cooler 200 decreases, while the temperature of the hot side increases. When the cold side of the thermoelectric cooler 200 is connected to the first air duct 300, the gas within the duct decreases in temperature as the cold side decreases, forming low-temperature gas. This low-temperature gas, under the action of the first fan 310, flows out of the first air outlet 120, achieving a cooling effect on the outside. When the hot side of the thermoelectric cooler 200 is connected to the first air duct 300, the gas within the duct increases in temperature as the hot side increases, forming high-temperature gas. This high-temperature gas, under the action of the first fan 310, flows out of the first air outlet 120, achieving a heating effect on the outside. This invention uses a semiconductor cooling chip 200 as a temperature regulation mechanism, replacing the micro compressor in the prior art. This reduces power consumption and allows the use of a built-in battery 400 with a lower energy storage capacity. Compared with micro compressors and power banks, using a semiconductor cooling chip 200 and a built-in battery 400 reduces the overall weight and solves the technical problem of heavy portable air conditioning devices in the prior art.
[0043] It should be noted that the semiconductor cooling chip 200 is existing technology, so its structure and working principle will not be described in detail here.
[0044] Specifically, the conductive component can be a wire, which electrically connects the battery 400 to the semiconductor cooling chip 200 and the first fan 310 respectively.
[0045] Please see Figure 2 and Figure 3Specifically, the housing 100 is equipped with several partitions 130, dividing the cavity into a battery compartment, a first air duct 300, and a heat dissipation compartment 500. The battery 400 is assembled in the battery compartment. The first air duct 300 is adjacent to the heat dissipation compartment 500. The heat dissipation compartment 500 has heat dissipation vents 530 on its wall, connecting it to the outside. A through-hole is formed in the partition 130 between the first air duct 300 and the heat dissipation compartment 500, and a thermoelectric cooler 200 is disposed at this through-hole. The cold side of the thermoelectric cooler 200 faces the interior of the first air duct 300, and the hot side faces the interior of the heat dissipation compartment 500; or, the hot side of the thermoelectric cooler 200 faces the interior of the first air duct 300, and the cold side faces the interior of the heat dissipation compartment 500. One side (cold or hot) of the thermoelectric cooler 200 is used to regulate the gas temperature in the first air duct 300, while the temperature change trend of the other side (hot or cold) is opposite to that of the former (cold or hot). The heat dissipation chamber 500 can disperse the gas in contact with the other side of the thermoelectric cooler 200 to the outside of the housing 100 through the heat dissipation port 530, thereby reducing the impact on the gas temperature in the first air duct 300.
[0046] Please see Figure 2 and Figure 3 In some embodiments, a first heat sink 320 is disposed in the first air duct 300, and the first heat sink 320 is in contact with the side (cold side or hot side) of the thermoelectric cooler 200 that is connected to the first air duct 300. The heat sink has better thermal conductivity than most gases, enabling faster heat transfer. Therefore, its temperature can quickly decrease or increase with the side of the thermoelectric cooler 200. Furthermore, since the surface area of the heat sink is larger than that of the thermoelectric cooler 200, it has a larger contact area with the gas in the first air duct 300, thus enabling more efficient heat transfer with the gas in the first air duct 300 and improving the heat transfer efficiency of the gas in the first air duct 300.
[0047] Please see Figure 2 and Figure 3 In some embodiments, a second heat sink 510 is disposed in the heat dissipation chamber 500, and the second heat sink 510 contacts the side (hot side or cold side) of the semiconductor cooling chip 200 facing the interior of the heat dissipation chamber 500. This is used to improve the heat transfer efficiency of the gas in the heat dissipation chamber 500, so that the air in the heat dissipation chamber 500 can absorb heat from the hot side or transfer heat to the cold side more quickly, further reducing the impact on the gas temperature in the first air duct 300.
[0048] Please see Figure 2 and Figure 3In some embodiments, a second fan 520 is configured in the heat dissipation chamber 500 and connected to the battery 400 via a conductive component, specifically a wire. A second air inlet 540 is also provided on the wall of the heat dissipation chamber 500, and the airflow direction of the second fan 520 is directed towards the heat dissipation inlet 530. The second fan 520 enables the gas in the heat dissipation chamber 500 to flow to the outside more quickly through the heat dissipation inlet 530, reducing the impact on the gas temperature inside the first air duct 300.
[0049] It is understandable that the function of the second air inlet 540 is not only to allow external air to flow into the heat dissipation chamber 500. When the second fan 520 in the heat dissipation chamber 500 is turned off, the second air inlet 540 can still be used to connect the inside of the heat dissipation chamber 500 with the outside, increase the air flow efficiency in the heat dissipation chamber 500, and achieve the effect of rapid heat dissipation. At this time, the function of the second air inlet 540 is the same as that of the heat dissipation port 530.
[0050] Please see Figure 1 , Figure 3 and Figure 4Furthermore, the portable air conditioner also includes a second air duct 600, which is a cylindrical shape with an opening on one side and a second air outlet 610 at one end. This opening is larger than the heat dissipation vent 530, covers the heat dissipation vent 530, and is detachably connected to the housing 100. Specifically, several clips are provided along the edge of the opening, and several matching slots are provided on the outer wall of the housing 100 where the heat dissipation vent 530 is located. The clips engage with the slots, achieving a detachable connection between the second air duct 600 and the housing 100. In use, the second air duct 600 is connected to the housing 100, and the battery 400 can supply power to the thermoelectric cooler 200, the first fan 310, and the second fan 520 respectively. When the thermoelectric cooler 200 is activated, its cold surface temperature decreases while its hot surface temperature increases. Taking the case where the cold side of the semiconductor cooling chip 200 is connected to the first air duct 300 (i.e., the cold side faces the interior of the first air duct 300) as an example, the gas in the first air duct 300 decreases in temperature as the cold side decreases, forming low-temperature gas. At this time, the hot side faces the heat dissipation chamber 500, which is connected to the second air duct 600. The gas in the heat dissipation chamber 500 and the second air duct 600 increases in temperature as the hot side increases, forming high-temperature gas. In applications requiring external cooling, the operator can start the first fan 310, and the low-temperature gas flows out of the first outlet 120 under the action of the first fan 310, achieving the effect of external cooling. In applications requiring external heating, the operator can start the second fan 520, and the high-temperature gas flows out of the second outlet 610 under the action of the second fan 520, achieving the effect of external heating. In some application scenarios, it may be necessary to simultaneously perform cooling and heating operations on different areas. This can be achieved by connecting the first air outlet 120 and the second air outlet 610 via pipes, and simultaneously activating the first fan 310 and the second fan 520 to guide the low-temperature gas and high-temperature gas to the target locations, thus performing both cooling and heating operations. It is understood that when the hot surface of the semiconductor cooling chip 200 is connected to the first air duct 300 (i.e., the hot surface faces the inside of the first air duct 300), the same function can be achieved. The difference from the aforementioned operation is that in this case, the first air duct 300 contains high-temperature gas, while the heat dissipation chamber 500 and the second air duct 600 contain low-temperature gas.
[0051] Please see Figure 1 and Figure 2 In some embodiments, a first grille 111 and / or a second grille 541 are provided at the first air inlet 110 and / or the second air inlet 540 to prevent debris from entering the first air duct 300 and / or the second air duct 600 with the airflow, thereby affecting the normal operation of the first fan 310 and / or the second fan 520. It should be noted that... Figure 1 and Figure 2The first air inlet 110 and the second air inlet 540 (one of the two second air inlets 540) are two parts of an air inlet. Specifically, a large air inlet is opened on the outer wall of the housing 100, which is connected to the first air duct 300 and the heat dissipation chamber 500. The air inlet is divided into two parts by the partition 130 inside the housing 100, which respectively form the first air inlet 110 and the second air inlet 540.
[0052] In some embodiments, a third grille is provided at the heat dissipation vent 530 to prevent debris from entering the heat dissipation chamber 500.
[0053] In some embodiments, a filter 330 is further disposed in the first air duct for filtering the airflow entering the first air duct 300.
[0054] Preferably, the filter 330 is installed at the first air inlet. When this utility model is used in a medical setting, a disposable medical meltblown fabric filter can be used.
[0055] Specifically, the housing 100 and the filter screen 330 are respectively provided with mounting ports that match the size of the filter screen 330, for the installation and removal of the filter screen 330.
[0056] Please see Figure 2 and Figure 3 In some embodiments, the portable air conditioner also includes a socket 700 disposed on the outer wall of the housing 100, which is connected to the semiconductor cooling chip 200 and the first fan 310 respectively via conductive components, which may be wires. This is used to connect to an external power source in some application scenarios (such as when the battery 400 is depleted), thereby improving the portable air conditioner's battery life.
[0057] Please see Figure 2 , Figure 3 and Figure 4 In some embodiments, a magnet 800 is fitted at the first air vent and / or the second air vent for magnetic connection with a pipe fitting having a magnet disposed at the interface.
[0058] Specifically, a groove can be provided along the circumference of the first air vent and / or the second air vent, and the annular magnet 800 can be assembled in the groove.
[0059] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, the scope of which is defined by the claims and their equivalents.
