[0035] Figure 1 and Figure 2 FIG2 shows a host 10 in an embodiment of the present invention, which can be used as an air conditioning device. Figure 3 and Figure 4 The host 10 includes a first housing 11, a cooling unit 12, and a main control unit (not shown). The cooling unit 12 is disposed within the first housing 11 and can perform cooling operations when connected to a power source. The main control unit is also disposed within the first housing 11 and is electrically connected to the cooling unit 12 to control its operation.

[0036] like Figure 5 As shown, the host 10 further includes a drainage unit 13 . The drainage unit 13 is disposed in the first housing 11 and is used to collect condensed water generated during the refrigeration process of the refrigeration unit 12 and discharge it outside the first housing 11 .

[0037] The drainage unit 13 includes a water storage pan 131, a drain pipe 132, and a water pump 133. The water storage pan 131 is positioned in correspondence with the refrigeration unit 12 and is used to collect condensed water generated during the refrigeration process of the refrigeration unit 12. The water inlet of the water pump 133 is connected to the water storage pan 131 and is used to pump the condensed water collected in the water storage pan 131. The drain pipe 132 is provided through the first housing 11, with one end connected to the water outlet of the water pump 133 and the other end connected to the space outside the first housing 11, for transporting the condensed water pumped by the water pump 133 to the outside of the first housing 11.

[0038] The present application provides a water storage tray 131 and a drain pipe 132 to collect and drain the condensed water generated during the refrigeration process of the refrigeration unit 12, thereby preventing the condensed water from being retained in the first housing 11 and affecting the service life of the device.

[0039] The present application provides power for the discharge of condensed water by providing a water pump 133. When using an air-conditioning device equipped with the main unit 10, there is no need to pay too much attention to the placement angle of the device. For air-conditioning devices used outdoors, there is no need to worry about the problem of condensed water not being able to be discharged due to the tilted placement of the device. The air-conditioning device equipped with the main unit 10 can be placed at a position with a larger tilt angle for use. There are also more options for the installation position of the drain pipe 132 on the first shell 11 and the installation position of the water storage tray 131 in the first shell 11.

[0040] For example Figure 1 and Figure 2 As shown, in some embodiments, the first housing 11 is longitudinally arranged and includes an outer shell 111 and a base 112. The outer shell 111 and the base 112 are detachably connected to define a space for accommodating the refrigeration unit 12.

[0041] In this embodiment, the base 112 is generally rectangular, and the housing 111 is a hollow shell structure with an open bottom and a closed top. The refrigeration unit 12 is mounted on the base 112. The housing 111 is buckled onto the base 112, and the base 112 can close the opening at the bottom of the housing 111.

[0042] In other optional embodiments, the base 112 may be configured as a hollow shell structure with an open top and a closed bottom. The housing 111 may be configured as a plate-like structure or as a hollow shell structure with an open bottom and a closed top. The refrigeration unit 12 and the drainage unit 13 may be mounted on the bottom wall of the base 112.

[0043] In other optional embodiments, the first shell 11 may also be cylindrical, semicircular, irregular, etc. When the base 112 or the shell 111 is plate-shaped, its shape may also be roughly polygonal, circular, irregular, etc.

[0044] For example Figure 3 and Figure 4 As shown, the refrigeration unit 12 includes an interconnected evaporation assembly 121, a condensation assembly 122, and a compression assembly 123. The evaporation assembly 121 absorbs heat from the air, cooling the air passing through it and producing cold air. The condensation assembly 122 releases heat to the surrounding air, reducing the heat content of the refrigerant passing through it. The compression assembly 123 compresses the refrigerant, converting it into a high-temperature, high-pressure gaseous state.

[0045] The evaporation assembly 121 includes an evaporator 1211 and a first fan 1212. The first fan 1212 allows air to flow through the evaporator 1211 to achieve heat exchange. The condensation assembly 122 includes a condenser 1221 and a second fan 1222. The second fan 1222 allows air to flow through the condenser 1221 to achieve heat exchange. The compression assembly 123 includes a compressor.

[0046] See also Figure 1 and Figure 2 The first housing 11 is further provided with a first air inlet 1111, a first air outlet 1112, a second air inlet 1113, and a second air outlet 1114. The first air inlet 1111 corresponds to the evaporator 1211. The first air outlet 1112 corresponds to the first fan 1212. The second air inlet 1113 corresponds to the condenser 1221. The second air outlet 1114 corresponds to the second fan 1222.

[0047] That is, two airflows are generated within the first housing 11. The first airflow, driven by the first fan 1212, enters the first housing 11 through the first air inlet 1111, passes through the evaporator 1211 and the first fan 1212, and exits the first housing 11 through the first air outlet 1112. The second airflow, driven by the second fan 1222, enters the first housing 11 through the second air inlet 1113, passes through the condenser 1221 and the second fan 1222, and exits the first housing 11 through the second air outlet 1114.

[0048] The first airflow can achieve a cooling effect under the action of the evaporator 1211. The second airflow can be heated up under the action of the condenser 1221.

[0049] The first air inlet 1111 and the first air outlet 1112 are arranged along the height direction at the first end of the first housing 11. The second air inlet 1113 and the second air outlet 1114 are arranged along the height direction at the second end of the first housing 11. The first end and the second end of the first housing 11 are opposite ends.

[0050] In this embodiment, the first air inlet 1111 , the first air outlet 1112 , the second air inlet 1113 , and the second air outlet 1114 are all disposed on the housing 111 , and are respectively disposed at two ends of the housing 111 in the longitudinal direction.

[0051] By arranging the first air inlet 1111 and the first air outlet 1112, and the second air inlet 1113 and the second air outlet 1114 at opposite ends of the first shell 11, if the host 10 is used in an outdoor air conditioning device, it can be convenient for users to place it during outdoor use.

[0052] Taking a tent environment as an example, the end of the first housing 11 with the first air inlet 1111 and the first air outlet 1112 can be placed inside the tent, while the end with the second air inlet 1113 and the second air outlet 1114 can be placed outside the tent. High-temperature air inside the tent can enter the first housing 11 through the first air inlet 1111 to be cooled, and then return to the tent through the first air outlet 1112. There is no need to worry about high-temperature air flowing into the tent through the second air inlet 1113 and the second air outlet 1114.

[0053] like Figure 3 As shown, in some embodiments, the compression assembly 123 can be disposed between the evaporation assembly 121 and the condensation assembly 122 in the longitudinal direction of the first housing 11. That is, the evaporation assembly 121 and the condensation assembly 122 can be located at the two ends (the aforementioned first end and second end) within the first housing 11, respectively, to correspond to the first air inlet 1111 and the first air outlet 1112, and the second air inlet 1113 and the second air outlet 1114, respectively.

[0054] In some embodiments, the first fan 1212 is disposed between the evaporator 1211 and the compression assembly 123. The first air outlet 1112 is located on the top side of the first air inlet 1111.

[0055] The evaporation component 121 also includes an air duct 1213, the two ends of which are respectively connected to the first fan 1212 and the housing 111, so that its two ends correspond to the air outlet of the first fan 1212 and the first air outlet 1112 respectively, and the output of the first fan 1212 is guided to the first air outlet 1112.

[0056] In some embodiments, the condenser 1221 is disposed at the top of the second fan 1222 , and the second air inlet 1113 is located on the top side of the second air outlet 1114 .

[0057] By arranging the condenser 1221 and the second fan 1222 in the vertical direction, the space occupied in the first shell 11 can be reduced to a certain extent, thereby miniaturizing the device and making it easier for users to carry it outdoors.

[0058] In some other optional embodiments, the evaporator 1211 may be disposed at the top of the first fan 1212, and the first air inlet 1111 may be disposed at the top of the first air outlet 1112. The second fan 1222 may also be disposed between the condenser 1221 and the compression assembly 123, with the second air outlet 1114 disposed on the top side of the second air inlet 1113, and an air duct 1213 may be provided to guide the air output by the second fan 1222 to the second air outlet 1114.

[0059] In some other optional embodiments, the compression assembly 123 may not be disposed between the evaporation assembly 121 and the condensation assembly 122. The evaporation assembly 121, the condensation assembly 122, and the compression assembly 123 can be flexibly arranged on the base 112, and by providing multiple air guides 1213, airflow can be guided to specific locations.

[0060] like Figure 3 and Figure 4 As shown, in some embodiments, the evaporator 1211 is plate-shaped and is vertically installed in the first housing 11 (vertically installed on the base 112). The horizontal axis of the evaporator 1211 is at an acute angle to the long axis of the first housing 11.

[0061] This arrangement allows the evaporator 1211 (and the first fan 1212 adjacent to the evaporator 1211) to be positioned at an angle within the first housing 11. While maintaining the dimensions of the first housing 11, the tilted evaporation assembly 121 can be configured with a larger size to improve heat exchange.

[0062] In some embodiments, the condenser 1221 can also be configured as a plate-like structure and tilted to the top of the second fan 1222 by a bracket or other components, forming a certain angle with the horizontal plane. This configuration can also increase the size of the condenser 1221 and improve the heat exchange effect.

[0063] like Figure 4As shown, when the evaporation component 121 is tilted in the first shell 11 and the compression component 123 is arranged between the evaporation component 121 and the condensation component 122, the compression component 123 can be arranged on one side of the long axis of the first shell 11 (installed on one side of the long axis of the base 112).

[0064] Such an arrangement allows the evaporation component 121, the condensation component 122 and the compression component 123 to be arranged adjacent to each other, further reducing the space occupied and achieving miniaturization of the equipment.

[0065] During operation of the main unit 10, the compression assembly 123 can output high-temperature refrigerant to the condensing assembly 122. The condenser 1221 of the condensing assembly 122 exchanges heat with the air via the second fan 1222. The air absorbs heat and rises in temperature, while the high-temperature refrigerant in the condenser 1221 releases heat, becoming low-temperature refrigerant. The low-temperature refrigerant is then transported via a pipeline to the evaporation assembly 121. The evaporator 1211 of the evaporation assembly 121 exchanges heat with the air via the first fan 1212. The air releases heat and cools down, while the low-temperature refrigerant in the evaporator 1211 absorbs heat and becomes high-temperature refrigerant, which is then transported back to the compression assembly 123, completing the cycle.

[0066] It should be understood that since the refrigerant flowing through the evaporator 1211 is a low-temperature refrigerant, the air in the evaporator 1211 is prone to condensation, which adheres to the outer wall of the evaporator 1211. Therefore, the water storage pan 131 can be located at the bottom of the evaporator 1211 to collect the condensation generated in the evaporator 1211.

[0067] like Figure 5 As shown, in this embodiment, the shape of the water storage tray 131 can be adapted to the shape of the bottom end of the evaporator 1211, and the evaporator 1211 can be installed in the water storage tray 131 through a fixing structure such as a bracket. This arrangement can not only achieve the effect of collecting condensed water in a centralized manner, but also reduce the size of components and the space occupied by the first housing 11, further realizing the miniaturization of the device.

[0068] In some other optional embodiments, a water storage tray 131 may be provided at the bottom of the condenser 1221. By providing two water storage trays 131, the collection effect of the condensed water in the first housing 11 is improved. Two water pumps 133 and two drain pipes 132 may also be provided to drain the condensed water in the two water storage trays 131 respectively.

[0069] In some other optional embodiments, the size of the water storage tray 131 may also be larger than the size of the evaporator 1211, and the water storage tray 131 may be set to correspond to the entire evaporation component 121 to receive the condensed water generated by the evaporation component 121 (including the pipeline).

[0070] In other optional embodiments, the water storage pan 131 may also be configured in other shapes, such as polygonal, irregular, etc. When the main body shape is adapted to the bottom end of the evaporator 1211, a portion of the main body may be provided with an outwardly protruding groove, so that when the evaporator 1211 is installed in the water storage pan 131, the sidewall where the groove is located can be spaced apart from the sidewall of the evaporator 1211, thereby facilitating the assembly and disassembly of the evaporator 1211.

[0071] like Figure 2 and Figure 5 As shown, when the second air inlet 1113 and the second air outlet 1114 are both located at the same end of the first shell 11, the drain pipe 132 is connected to the space outside the first shell 11 at the second end of the first shell 11, that is, its penetration position on the first shell 11 is at the same end as the positions of the second air inlet 1113 and the second air outlet 1114 on the first shell 11.

[0072] When the host 10 is used in an outdoor air-conditioning device, such a setting can facilitate user use.

[0073] Taking a tent environment as an example, during use, the end of the first shell 11 provided with the first air inlet 1111 and the first air outlet 1112 is placed inside the tent, while the end provided with the second air inlet 1113 and the second air outlet 1114 is placed outside the tent. Therefore, by connecting the drain pipe 132 at the second end of the first shell 11 to the space outside the first shell 11, condensed water can be smoothly drained out of the tent. In other words, such a setup does not require consideration of the placement of the main unit 10, and there is no need to worry about high-temperature air flowing into the tent through the second air inlet 1113 and the second air outlet 1114, nor does it need to worry about condensed water flowing into the tent. This can greatly improve the user experience.

[0074] It should be understood that "the drain pipe 132 is connected to the space outside the first shell 11 at the second end of the first shell 11" can be understood as being located at the second end of the first shell 11, or can be understood as being located near the second end of the first shell 11 (for example, located at the second end of one of the side walls parallel to the long axis direction of the first shell 11, etc.), and no specific limitation is given here.

[0075] like Figure 5 and Figure 6 As shown, in some embodiments, the drain pipe 132 includes a first pipe section 1321 and a second pipe section 1322. The first pipe section 1321 is disposed adjacent to the base 112, and the second pipe section 1322 is spaced apart and located above the base 112.

[0076] By installing the drain pipe 132 on the base 112, with at least a portion of the pipe extending adjacent to the base 112, the stability of the installation of the drain pipe 132 can be improved, thereby increasing the service life of the main unit 10. By arranging a portion of the drain pipe 132 to be spaced apart from the base 112, it can provide space to avoid affecting the installation of other components within the first housing 11, effectively utilizing the space within the first housing 11, and further miniaturizing the device.

[0077] Specifically, the second pipe section 1322 can be arranged in an inverted concave shape, with one end connected to the water pump 133 via a horizontal third pipe section 1323, and the other end connected to one end of the first pipe section 1321. The first pipe section 1321 can be arranged along the edge of the base 112, extending parallel to and adjacent to the base 112, and extending to the second end of the base 112 (the second end of the first housing 11).

[0078] Since the first fan 1212 needs to be installed as close as possible to the evaporator 1211 to achieve the effect of airflow passing through the evaporator 1211 for heat exchange, when the water storage pan 131 is installed at the bottom end of the evaporator 1211, if the drain pipe 132 is directly led out, it may affect the installation of the first fan 1212.

[0079] By setting a horizontal third pipe section 1323 between the water pump 133 and the second pipe section 1322, the end of the second pipe section 1322 close to the water storage tray 131 can be set at a corner of the water storage tray 131 to avoid occupying space. By setting the second pipe section 1322 to an inverted concave structure, the drain pipe 132 can be vertically led out on one side of the water storage tray 131 and the first fan 1212, without occupying the space between the water storage tray 131 and the first fan 1212, nor occupying the space at the bottom of the first fan 1212, thereby avoiding space waste. By extending the first pipe section 1321 along the side of the base 112, the corner space in the first shell 11 can be effectively utilized to complete the installation of the equipment.

[0080] In some other optional embodiments, the third pipe section 1323 may not be provided, and the water pump 133 may be provided at a corner of the water storage tray 131 , and one end of the second pipe section 1322 may be directly connected to the water pump 133 .

[0081] In some other optional embodiments, the second pipe section 1322 may be configured as another arc-shaped structure so as to be led out from one side of the first fan 1212 .

[0082] In some other optional embodiments, when the first fan 1212 and the evaporator 1211 are arranged in a vertical structure, it is not necessary to consider the lead-out problem of the drain pipe 132. In this case, the water storage tray 131 can be used as a bracket to achieve the installation of the evaporator 1211.

[0083] In some embodiments, the water pump 133 can be a submersible pump installed in the water storage tray 131 , with the water inlet located at the bottom of the cavity of the water storage tray 131 .

[0084] In some embodiments, the drainage unit 13 may further include a one-way valve 134 . The one-way valve 134 is disposed on the drainage pipe 132 to control the flow direction of the condensed water in the drainage pipe 132 to prevent the condensed water from flowing back into the water storage tray 131 .

[0085] In this embodiment, the one-way valve 134 is disposed on the second pipe section 1322 , and is disposed at a position where the second pipe section 1322 is located at the top of the first fan 1212 .

[0086] In some other optional embodiments, the one-way valve 134 can also be set at other positions of the second pipe section 1322.

[0087] In some embodiments, the drainage unit 13 further includes an air bag 135. The air bag 135 is disposed on the drainage pipe 132 to assist in discharging air entering the drainage pipe 132.

[0088] In this embodiment, the end of the first pipe section 1321 of the drain pipe 132 away from the second pipe section 1322 is located outside the first shell 11 , and the airbag 135 is disposed on the pipe section located outside the first shell 11 .

[0089] In some other optional embodiments, the air bag 135 can also be provided on the pipe section of the drainage pipe 132 located inside the first housing 11. The drainage pipe 132 can also be entirely provided inside the first housing 11.

[0090] In some embodiments, the drainage unit 13 may further include a water level sensor (not shown), which may be disposed within the water reservoir 131 to monitor the water level within the water reservoir 131 and prevent water from flowing out due to excessively high levels. The main control unit may be electrically connected to the water pump 133 and the water level sensor. When the water level sensor detects that the water level has reached a safe height, it outputs a control signal to the main control unit. Upon receiving the control signal, the main control unit activates the water pump 133 to initiate drainage.

[0091] The provision of the water level sensor can make it possible for the electronic control components of the drainage unit 13 (such as the water pump 133) to not be always in the open state. When the water level reaches a certain level, the drainage operation can be automatically realized.

[0092] like Figure 1 As shown, in some embodiments, an ambient light 1116 may be provided around the first air outlet 1112. The main control unit may control the color and / or brightness of the ambient light 1116 according to the change in the outlet air temperature to enhance the user experience.

[0093] In some embodiments, a first handle 1115 may be further provided on the housing 111 . The first handle 1115 is disposed on the top of the housing 111 . The first handle 1115 may facilitate a user in carrying the air conditioner.

[0094] In some embodiments, the upper housing 211 may further be provided with at least one second handle 2113 for conveniently taking the power supply device 20. Specifically, the second handle 2113 is provided on the side wall of the upper housing 211, and the number may be two, respectively provided on the left and right sides of the upper housing 211.

[0095] like Figure 8 As shown, the present application also constructs a portable air conditioner 1, which can be used in outdoor activities such as camping, is simple and convenient to use, and is easy for users to carry. It can include a host 10 under any of the above embodiments.

[0096] See also Figure 9 The portable air conditioner 1 may further include at least one power supply device 20 for supplying power to the host 10. The at least one power supply device 20 may be a portable energy storage device that can be mechanically, electrically and detachably connected to the host 10.

[0097] When there are two or more power supply devices 20, they can be conveniently connected in series to jointly power the host 10. In this way, two or more power supply devices 20 can significantly increase the battery life of the host 10.

[0098] like Figure 10 and Figure 11 As shown, the power supply device 20 includes a second housing 21 and a battery unit 22. The battery unit 22 is disposed within the second housing 21 and is used to store electrical energy. The first housing 11 and the second housing 21 are detachably connected, and the host 10 and the power supply device 20 are detachably connected by disassembling and assembling the two.

[0099] By arranging the first housing 11 and the second housing 21 to be detachably connected, the main unit 10 and the power supply unit 20 can be assembled into a single, integrated structure, making it easier for the user to carry and transport. When the portable air conditioner 1 is needed outdoors, the main unit 10 and the power supply unit 20 can be moved as a whole. Furthermore, there is no need to worry about the placement of the power supply unit 20 and the main unit 10 during use, which reduces space usage and improves the user experience.

[0100] like Figures 9 to 11 As shown, the second housing 21 is a vertically elongated flat pancake-shaped structure, comprising an upper housing 211 and a lower housing 212. The upper housing 211 and the lower housing 212 are detachably connected to define a space for receiving the battery unit 22.

[0101] In this embodiment, the lower housing 212 is generally rectangular and plate-shaped, and its dimensions are generally compatible with the first housing 11, thereby enhancing the aesthetic appearance of the portable air conditioner 1. The upper housing 211 is a hollow housing structure with an open bottom and a closed top. The lower housing 212 can close the opening at the bottom of the upper housing 211.

[0102] In some other optional embodiments, the lower shell 212 can also be configured as a hollow shell structure with an open top and a closed bottom. The upper shell 211 can be configured as a plate-like structure or a hollow shell structure with an open bottom and a closed top.

[0103] In other optional embodiments, the second shell 21 can also be arranged in other shapes such as cylindrical, semicircular, irregular, etc. When the lower shell 212 or the upper shell 211 is arranged in a plate shape, its shape can also be roughly polygonal, circular, irregular, etc.

[0104] In this embodiment, the power supply device 20 is detachably disposed at the bottom of the host 10 , and the base 112 and the upper shell 211 are detachably connected.

[0105] By arranging the power supply device 20 at the bottom of the host 10, the center of gravity of the host 10 can be lowered, the stability of the device can be improved, and the device can be prevented from tipping over when placed in an outdoor environment.

[0106] In some other optional embodiments, the power supply device 20 can also be detachably disposed on a side or top of the host 10 .

[0107] In some embodiments, at least one hook 2111 is provided on one of the base 112 and the upper housing 211, and at least one engaging portion 1121 is correspondingly provided on the other. The hook 2111 and the engaging portion 1121 are detachably connected to achieve a detachable connection between the power supply device 20 and the host 10.

[0108] like Figure 6 and Figure 9As shown, in this embodiment, the lower end surface of the base 112 is provided with four engaging portions 1121, which are arranged in groups of two on the lower wall surface of the bottom wall of the base 112 and are respectively arranged on both sides of the base 112, and are symmetrically arranged along the long axis of the base 112. The upper shell 211 is correspondingly provided with four hooks 2111, which are arranged in groups of two on the upper wall surface of the top wall of the upper shell 211 and are respectively arranged on both sides of the top wall of the shell 211, and are symmetrically arranged along the long axis of the upper shell 211.

[0109] In other optional embodiments, the number of the engaging portions 1121 and the hooks 2111 can be two, three, five, etc. They can also be arranged at other positions of the first shell 11 and the second shell 21 .

[0110] In some embodiments, a slot is formed on the hook 2111 to limit the engagement portion 1121 . When the engagement portion 1121 is limited in the slot of the hook 2111 , the hook 2111 and the engagement portion 1121 can be considered to be detachably connected together.

[0111] In this embodiment, the slot is provided through both ends along the first direction. The engaging portion 1121 can be moved into the slot of the hook 2111 by sliding in the first direction, thereby achieving removable retention. That is, when the host 10 and the power supply device 20 need to be assembled together, the engaging portion 1121 can be retained in the slot by sliding the host 10 and the power supply device 20 relative to each other.

[0112] It should be understood that the specific orientation of the first direction should be determined based on the setting angle of the locking portion 1121 and the hook 2111.

[0113] Taking this embodiment as an example, Figure 6 and Figure 9 As shown, the first direction is the direction in which the long axes of the first shell 11 and the second shell 21 extend. The connecting line of the two ends of each hook 2111 that are connected by the slot is parallel to the long axis of the second shell 21.

[0114] See also Figure 8 During assembly of the host 10 and the power supply device 20, the first housing 11 and the second housing 21 are first aligned parallel to each other along their long axes. The first housing 11 is then positioned at one end of the long axis of the second housing 21, with the sidewall of the first housing 11 where the engaging portion 1121 is located adjacent to the sidewall of the second housing 21 where the hook 2111 is located. The first housing 11 is then moved along its long axis toward the other end of the second housing 21. During this movement, the engaging portion 1121 is retained within the slot of the hook 2111, achieving removable positioning.

[0115] In some other optional embodiments, the arrangement angles of the engaging portion 1121 and the hook 2111 can also be such that the first direction is the opposite direction of the extension of the short axis of the first shell 11 and the second shell 21, or any direction between the long axis and the short axis of the first shell 11 and the second shell 21.

[0116] By providing the hook 2111 with a slot and the engaging portion 1121, the host 10 and the power supply device 20 can be detachably connected by relative sliding. This disassembly and assembly method is convenient for users to operate quickly outdoors and improves the user experience.

[0117] In some other optional embodiments, one of the first shell 11 and the second shell 21 may be provided with a guide rail, and the other may be provided with a slider, so that the two may be detachably connected by relative sliding.

[0118] In some other optional embodiments, the first shell 11 and the second shell 21 can be detachably connected by providing a snap-fit ​​structure, bolts or other connecting parts.

[0119] For example Figure 6 and Figure 9 As shown, in some embodiments, a limiting structure 113 is further provided on one of the base 112 and the upper housing 211, and a corresponding mating portion 2112 is provided on the other of the two. The mating portion 2112 is detachably connected to the limiting structure 113 to limit the relative movement of the host 10 and the power supply device 20 in the first direction.

[0120] Due to the arrangement of the hook 2111 and the engaging portion 1121, the main unit 10 and the power supply device 20 are not restricted in the first direction. During outdoor use, if the portable air conditioner 1 is tilted, there is a potential for the main unit 10 and the power supply device 20 to become detached from each other. The provision of the limiting structure 113 and the engaging portion 2112 prevents relative movement of the main unit 10 and the power supply device 20 in the first direction, improving their assembly stability.

[0121] In some embodiments, the limiting structure 113 can be movably disposed on one of the base 112 and the upper housing 211 and includes a movable position and a fixed position.

[0122] When the limiting structure 113 is in the active position, the limiting structure 113 is spaced apart from the mating portion 2112. The host 10 and the power supply device 20 can now move in the first direction. When the limiting structure 113 is in the fixed position, the mating portion 2112 is restrained by the limiting structure 113. The host 10 and the power supply device 20 are now restricted in the first direction and cannot move relative to each other.

[0123] like Figure 6 and Figure 7 As shown, in some embodiments, the limiting structure 113 may include a limiting portion 1131, a driving portion 1132, and a return spring 1133. The driving portion 1132 is fixed to the limiting portion 1131. The driving portion 1132 is configured to be driven by a user to move the limiting structure 113. The limiting portion 1131 is configured to limit the mating portion 2112. The return spring 1133 is disposed on the driving portion 1132 or the limiting portion 1131 and is configured to return the limiting portion 1131 from its active position to its fixed position after the user stops driving.

[0124] Specifically, the base 112 can be formed with a drive hole and a limit hole. The drive portion 1132 can be movably inserted into the drive hole, and the limit portion 1131 can be movably inserted into the limit hole. The other end of the return spring 1133 can abut against the base 112. The limit portion 1131 is formed with a limit groove for accommodating the mating portion 2112. The opening of the limit groove is perpendicular to the first direction.

[0125] The elastic force of the return spring 1133 maintains the retaining structure 113 in a fixed position when not driven by external forces. To assemble the main unit 10 and the power supply unit 20, the user can move the main unit 10 and the power supply unit 20 in the first direction to adjacent positions. The user can then activate the drive unit 1132, compressing the return spring 1133 and moving the retaining structure 113 to the active position. At this point, the main unit 10 and the power supply unit 20 can be further moved in the first direction until they are in place.

[0126] When both are in place, the opening of the limiting slot of the limiting portion 1131 aligns with the mating portion 2112. The user can now release the driver 1132. Driven by the return spring 1133, the limiting structure 113 returns to its fixed position. The limiting portion 1131 receives the mating portion 2112 within the limiting slot through its opening, achieving positional limitation in the first direction.

[0127] By providing the limiting structure 113 , the user's operation steps can be further simplified, and the rapid assembly of the host 10 and the power supply device 20 can be facilitated.

[0128] In this embodiment, the drive hole is formed on the side wall of the base 112, and the stop hole is formed on the bottom wall of the base 112. The matching portion 2112 is provided on the top wall of the upper shell 211, corresponding to the stop groove of the stop portion 1131 located in the fixed position. Both can be provided at the ends of the long axis of the base 112 and the upper shell 211, respectively.

[0129] In some other optional embodiments, the ends of the first housing 11 and the second housing 21 may be provided with snap-fit ​​structures for mutually positioning by interference fit. When the two are slid into position along the first direction, the snap-fit ​​structures at the ends engage with each other to form an interference fit, thereby limiting further movement of the two in the first direction.

[0130] In some other optional embodiments, a single connecting member such as a bolt may be provided between the first shell 11 and the second shell 21 to achieve a limiting effect in the first direction after the two are slidably assembled into place.

[0131] In some other optional embodiments, the limiting structure 113 can be simply configured as a slot-shaped structure with an opening facing the first direction. When the host 10 and the power supply device 20 move relative to each other along the first direction, causing the mating portion 2112 to move from the opening into the limiting structure 113, it can serve as a reminder to the user that the two are properly assembled.

[0132] like Figures 9 to 11 As shown, the power supply device 20 also includes a battery unit 22, a cable 23, and a control unit (not shown in the figure). The battery unit 22 and the control unit are both arranged in the second shell 21, and the control unit is also electrically connected to the battery unit 22 to control the output of the battery unit 22 power, or to communicate with the host 10 or other power supply devices 20. One end of the cable 23 is inserted into the second shell 21 and is electrically connected to the control unit. The other end of the cable 23 extends outside the second shell 21 and is used to electrically connect to the host 10 to supply power to the host 10 and communicate with the host 10, or the other end of the cable 23 is also connected in series with other power supply devices 20.

[0133] For example Figure 2 As shown, the base 112 is provided with a first interface 1122 for electrically connecting to the power supply device 20, supplying power to the host 10, and communicating with the host 10. The first interface 1122 includes a customized first power transmission line and a customized first signal transmission line. The first power transmission line is electrically connected to the refrigeration unit 12, and the first signal transmission line is electrically connected to the main control unit. Specifically, the number of the first power transmission lines is two, and the number of the first signal transmission lines is four. In some embodiments, both the first power transmission line and the first signal transmission line can use pins, that is, in this embodiment, the first interface 1122 is a female connector with customized six pins, and one side can simultaneously transmit power and control signals.

[0134] See also Figure 11In some embodiments, the lower housing 212 is further provided with a second interface 2125. The second interface 2125 includes a customized second power transmission circuit and a customized second signal transmission circuit. The second power transmission circuit is electrically connected to the battery unit 22 and the control unit respectively, and the second signal transmission circuit is electrically connected to the control unit.

[0135] Specifically, the number of the second power transmission lines can be two, and the number of the second signal transmission lines can be four. In some embodiments, both the second power transmission lines and the second signal transmission lines can use pins. That is, in this embodiment, the second interface 2125 is a female connector with customized six pins, which can simultaneously transmit power and control signals.

[0136] The second interface 2125 can be used to connect to an external power source to charge the battery unit 22; it can also be connected to the cable 23 of other power supply devices 20 to be connected in series with other power supply devices 20 to realize the transmission of power and control signals.

[0137] In some embodiments, a third interface 231 is provided at the free end of the cable 23. The third interface 231 includes a customized third power transmission line and a customized third signal transmission line. The third power transmission line is electrically connected to the battery unit 22 and the control unit, respectively, and the third signal transmission line is electrically connected to the control unit. Specifically, there are two third power transmission lines and four third signal transmission lines. In some embodiments, both the third power transmission line and the third signal transmission line can utilize pins. That is, in this embodiment, the third interface 231 is a male connector with customized six pins. The third interface 231 can be respectively adapted to the first interface 1122 and the second interface 2125 to achieve transmission of power and control signals.

[0138] In some embodiments, at least two power supply devices 20 can be connected in series to form a power supply device combination. Taking three power supply devices 20 as an example, the third interface 231 of the second power supply device 20 is connected to the second interface 2125 of the first power supply device 20, and the third interface 231 of the third power supply device 20 is connected to the second interface 2125 of the second power supply device 20, and so on. The power supply devices are connected in series to form a power supply device combination to transmit power and signals to the host 10 together.

[0139] During actual use, multiple power supply devices 20 can be connected and arranged, with the third interface 231 of the cable 23 of one power supply device 20 electrically connected to the first interface 1122 on the base 112 of the air conditioner, and the third interfaces 231 of the cables 23 of the remaining power supply devices 20 are sequentially connected to the second interfaces 2125 on adjacent power supply devices 20, thereby achieving a series connection of multiple power supply devices 20. It should be understood that due to the presence of the second interface 2125, the power supply device 20 can also be connected to an external power source while supplying power to charge the battery unit 22 of the power supply device 20.

[0140] See also Figure 10 The third interface 231, the second interface 2125, and the first interface 1122 each include two power transmission lines and four signal transmission lines, two of which are used to transmit high currents, and the other four signal transmission lines are used to transmit protocol signals. Specifically, of the four signal transmission lines, two can be used to transmit 485 serial communication signals, and one of the other two signal transmission lines is used to transmit battery cascade detection signals, and the other is used for air conditioning detection signals. In this way, power and control signals can be transmitted between the power supply device 20 and the host 10, as well as between the power supply device 20 and other power supply devices 20.

[0141] like Figure 11 As shown, in some embodiments, a cable winding portion 2122 may be further provided on the lower end surface of the lower housing 212 for winding and accommodating the cable 23 to avoid a cluttered arrangement of the cable 23. One end of the cable 23 is passed through the bottom wall of the lower housing 212 and electrically connected to the battery cell 22 in the space between the lower housing 212 and the upper housing 211. The remaining portion is located on the lower side of the lower wall surface of the bottom wall of the lower housing 212 and is wound around the cable winding portion 2122.

[0142] The lower housing 212 also includes a cable receiving slot 2123 and a port receiving slot 2124 for accommodating the free end of the cable 23 for electrical connection to the battery unit 22. The port at the free end is received within the port receiving slot 2124 via the cable receiving slot 2123. This allows for convenient storage and positioning of the cable 23, eliminating the need for external cables connecting the battery unit 22 to the main unit 10.

[0143] A support leg 2121 may be provided on the lower end surface of the lower shell 212 of the second shell 21 to facilitate supporting and placing the portable air conditioner 1 .

[0144] See also Figure 8In some embodiments, a power switch 2126 and a battery indicator may be further provided on the lower housing 212. The power switch 2126 is used to control the power supply device 20 to be turned on and off. The battery indicator is used to display the remaining power of the battery unit 22.

[0145] The power switch 2126 can be an AC power switch. A long press can turn it on and off, and it can automatically shut down if there is no load for 30 minutes. A short press can turn the battery indicator on and off. The battery indicator can select a battery code tube to display the remaining power.

[0146] In this embodiment, the battery unit 22 may include, but is not limited to, fifty-six battery elements, which may be arranged in groups of four in a rectangular shape, with each group arranged side by side. The total capacity may be, but is not limited to, 5000 mAh, the total power may be, but is not limited to, 960 Wh, the full-charge voltage may be, but is not limited to, 58.8 V, and the shutdown voltage may be, but is not limited to, 40.6 V. It is understood that the number of battery elements may be adjusted as needed.

[0147] It's important to note that the battery unit 22 charging input (i.e., second port 2125) has a current limit of 10A and a power limit of 500W. It supports charging with a 500W / 50V adapter, 11-75V MPPT buck-boost charging, solar charging, and 11V-13V cigarette lighter charging. The second port 2125 also features reverse polarity protection and overcharge protection. The battery unit 22's output current is limited to 25A, with short-circuit and undervoltage protection.

[0148] Figure 12 The circuit principle block diagram of the power supply device 20 is shown. Figure 12 It can be seen that the circuit part of the power supply device 20 may include an input port, a DC-DC buck-boost controller, a battery unit 22, an output controller, an air-conditioning power supply interface, a DC and PD fast charging power supply interface, a microcontroller, a battery pack cascade uplink communication interface, and a battery pack cascade downlink communication interface.

[0149] Among them, the input port (i.e., the second interface 2125) is used for power input. The DC-DC buck-boost controller is electrically connected to the input port to perform step-up or step-down conversion on the voltage of the input power supply to charge the battery unit 22. The battery unit 22 is also electrically connected to the output controller, which is used to control the external power supply output of the battery unit 22. The output controller is also electrically connected to the air conditioner power supply interface and the DC and PD fast charging power supply interface respectively. The air conditioner power supply interface is used to be electrically connected to the first interface 1122 through a cable 23 to realize the power supply function of the air conditioner. The DC and PD fast charging power supply interface includes a 12V 150W DC output, a PD 100W TypeC, and a QC3.0 18W TypeA USB output.

[0150] In addition, the DC-DC buck-boost controller is also electrically connected to a microcontroller, which is used to control the DC-DC buck-boost controller and the external output and external communication connection functions of the battery unit 22. The microcontroller is also electrically connected to the battery pack cascade upstream communication interface and the battery pack cascade downstream communication interface, and is used to connect to the four first signal transmission lines of the first interface 1122 for transmitting protocol signals. Similarly, the air conditioner power supply interface is used to electrically connect the two first power transmission lines in the first interface 1122 for transmitting high current.

[0151] In some embodiments, the power supply device 20 may also have, but is not limited to, one TypeC 100W output, one USB 18W QC3.0 output, and one regulated 12V 150W Anderson output.

[0152] In some embodiments, the power supply device 20 may also have functions such as overcharge / overdischarge protection, output short circuit protection, input reverse connection protection, low temperature protection, and high temperature protection.

[0153] During specific use, when the power supply device 20 is in an inactivated state, after the cable 23 of the power supply device 20 is connected to the first interface 1122, the power supply device 20 can be automatically activated without pressing the power switch 2126.

[0154] When multiple power supply devices 20 are connected in sequence to power the host 10, they support cascading power supply. The power supply device 20 closest to the host 10 is prioritized for power supply, while the other power supply devices 20 remain inactive until the power supply device 20 closest to the host 10 runs out of power. At this point, the power supply device 20 next closest to the host 10 is activated, and so on. When no external charging device is connected, the power supply devices 20 do not charge each other.

[0155] It should be noted that the above-mentioned “closest to the host 10 ” and “second closest to the host 10 ” refer to “directly connected to the first interface 1122 ” and “indirectly connected to the first interface 1122 via a power supply device 20 ”.

[0156] When multiple power supply devices 20 need to be charged, the power supply device 20 supports cascade charging, that is, the power supply device 20 in the discharging state is charged first. When all power supply devices 20 are in the inactive state, the power supply device 20 farthest from the external power source is charged first.

[0157] It should be understood that the above “farthest from the external power source” refers to “electrically connected to the external power source through the remaining power supply devices 20 ”.

[0158] In some embodiments, when cascade charging is performed, if the activated power supply device 20 was automatically shut down before, it can be automatically turned on during the cascade charging process.

[0159] In some embodiments, the power supply device 20 also has a simultaneous charging and discharging function. When a single power supply device 20 is simultaneously charging and discharging, if the load power is greater than the charging power, the power supply device 20 will make up for the shortfall; if the load power is less than the charging power, the excess power will be used to charge the power supply device 20.

[0160] When multiple power supply devices 20 are connected in sequence and charge and discharge at the same time, charging and power supply are preferentially performed by the power supply device 20 closest to the host 10. The external power supply charges the power supply device 20 closest to the host 10, and at the same time, the power supply device 20 closest to the host 10 charges the host 10 until the power supply device 20 closest to the host 10 is out of power (load power is greater than charging power) or fully charged (load power is less than charging power), and then the power supply device 20 second closest to the host 10 is activated for charging, and so on.

[0161] In some embodiments, the power supply device 20 supports charging from external power sources such as solar energy, adapter / charger, and car cigarette lighter.

[0162] In some embodiments, whether the power supply device 20 is activated manually or automatically, the output of the battery unit 22 is turned on, and if the host 10 is not detected within thirty minutes, the output is automatically turned off.
