[0002] Generally, the power adapter has an input end and an output end, wherein the input end is used to connect to the mains AC power, and the output end is used to output DC power to the intelligent furniture equipment, such as intelligent bed, intelligent table, electric sofa, etc.
[0003] In the case of the power adapter connecting to the mains, the intelligent furniture equipment works normally, however, once the mains power outage occurs, the power adapter will lose the input voltage, resulting in that the intelligent furniture equipment immediately loses the power supply. In order to ensure that the equipment can operate normally, a battery pack will be used to make the battery pack continue to run the equipment, but during the power outage to the battery pack power supply, the intelligent furniture equipment is in a power-off state, which will cause serious consequences, such as data loss, system abnormality, etc. for some equipment (such as medical instruments, smart TVs, etc.) that need to rely on continuous power supply to maintain functions or data integrity, and the switching to the backup power supply is not convenient in operation.
[0004] Therefore, the equipment needs to rely on manual operation or other external systems to start the backup power supply (such as the battery pack) after the power outage, so that seamless power supply switching cannot be realized. UTILITY MODEL CONTENT

[0030] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below in combination with specific embodiments:
[0031] Referring to Figure 1 , which is a double-head power adapter 10 according to an embodiment of the present disclosure.
[0032] Referring to Figure 4 , the double-head power adapter 10 includes a voltage input assembly 100, a rectifier transformer 200, and a voltage output assembly 300. The voltage input assembly 100 includes an input cable 110 and an input plug 120. The input plug 120 includes a main power plug 121 and a backup power plug 122 connected to each other. The backup power plug 122 is used to be electrically connected to the power output end of a battery pack. The main power plug 121 and the backup power plug 122 are both electrically connected to the voltage input end of the input cable 110. The voltage output end of the input cable 110 is electrically connected to the voltage input end of the rectifier transformer 200. The voltage output assembly 300 includes an output cable 310 and an output socket 320. The voltage output end of the rectifier transformer 200 is electrically connected to the DC input end of the output cable 310. The DC output end of the output cable 310 is electrically connected to the output socket 320. The output socket 320 is used to be connected to an external device.
[0033] In the embodiment, the double-head power adapter 10 has a commercial power plug 121 and a backup power plug 122, wherein the commercial power plug 121 is used to connect to commercial power, and the backup power plug 122 is used to connect to a battery pack. In general, the double-head power adapter 10 selects commercial power to supply power to the device, and when the commercial power is suddenly interrupted, the double-head power adapter 10 has no commercial power input, so that the battery pack is used to supply power to the device. From the time when the commercial power is interrupted to the time when the battery pack supplies power, the device is always powered on. It is more friendly to some devices that rely on continuous power supply to maintain functions or data integrity, such as medical instruments. In this way, when the commercial power is interrupted, the battery pack immediately supplies continuous power to the device, so that the convenience of switching power supply is good. It can be understood that the commercial power plug 121 is usually connected to alternating current. The external alternating current is rectified and transformed by the rectifier transformer 200 to supply power to the device. When the commercial power is suddenly interrupted, the power supply is switched to the battery pack. The battery pack provides direct current. After being transformed by the rectifier transformer 200, the direct current continues to supply power to the device.
[0034] In one of the embodiments, the included angle between the center line of the commercial power plug 121 and the center line of the backup power plug 122 is in the range of 90°-180°. In the embodiment, as shown in Figure 2 , the included angle between the center line of the commercial power plug 121 and the center line of the backup power plug 122 is 180°.
[0035] In one of the embodiments, the included angle between the commercial power plug 121 and the input cable 110 is in the range of 90°-150°. In the embodiment, as shown in Figure 2 , the included angle between the commercial power plug 121 and the input cable 110 is 90°.
[0036] In one of the embodiments, the included angle between the backup power plug 122 and the input cable 110 is in the range of 90°-150°. In the embodiment, as shown in Figure 2 , the included angle between the backup power plug 122 and the input cable 110 is 90°.
[0037] As shown in Figure 5 , in one of the embodiments, the output socket 320 includes an A socket 321 and a C socket 322 connected in series. The A socket 321 and the C socket 322 are both used to connect external devices, and the A socket 321 and the C socket 322 are both electrically connected to the direct current output end of the rectifier transformer 200. It can be understood that for some devices that need to be connected to power through a USB-A connector, the USB-A connector can be connected to the A socket 321 to be powered on. For some devices that need to be connected to power through a USB-C connector, the USB-C connector can be connected to the C socket 322 to be powered on. Therefore, the output socket 320 simultaneously designs the A socket 321 and the C socket 322, which can adapt to more types of devices.
[0038] As shown in Figure 2 In one of the embodiments, the center line of the input cable 110 coincides with the center line of the output cable 310, and thus, the input cable 110 and the output cable 310 can be symmetrically arranged with the rectifier transformer 200 as the center point.
[0039] In one of the embodiments, the mains power plug 121 and the backup power plug 122 are integrally formed. It can be understood that, when the input plug 120 is produced, the mains power plug 121 and the backup power plug 122 are integrated, so that the overall structure of the input plug 120 is more compact, thereby reducing the overall volume of the input plug 120.
[0040] As shown in Figure 2 and Figure 3 In one of the embodiments, the rectifier transformer 200 includes a protective shell 210 and a rectifier transformer circuit board 220, the protective shell 210 is provided with a receiving cavity 201, the rectifier transformer circuit board 220 is located in the receiving cavity 201, the voltage output end of the input cable 110 is electrically connected with the input end of the rectifier transformer circuit board 220, and the direct current input end of the output cable 310 is electrically connected with the output end of the rectifier transformer circuit board 220. It can be understood that the rectifier transformer circuit board 220 is used for rectifying and transforming the input alternating current or direct current to supply power to the equipment, and the rectifier transformer circuit board 220 is located in the receiving cavity 201, i.e. installed inside the protective shell 210, so as to prevent the rectifier transformer circuit board 220 from being exposed and thus prevent the rectifier transformer circuit board 220 from being easily damaged.
[0041] In combination with Figure 1 In one of the embodiments, the rectifier transformer 200 further includes an indicator lamp 230, the state display end of the rectifier transformer circuit board 220 is electrically connected with the indicator lamp 230, and the indicator lamp 230 is embedded in the protective shell 210. In this embodiment, when the mains power plug 121 or the backup power plug 122 is connected to power, the rectifier transformer circuit board 220 receives a voltage signal, and the signal is displayed in the form of the indicator lamp 230, i.e. when the input plug 120 is connected to power, the indicator lamp 230 is lighted, thereby playing a role of informing the user.
[0042] The present disclosure also provides a smart furniture device, which includes a device main body and the double-head power adapter 10 of any one of the above embodiments, and the device main body is pluggably connected with the double-head power adapter 10. In this embodiment, the device main body can be connected to power through the A socket 321 or the C socket 322. It can be understood that the device main body can be one of an electric sofa, a lifting table, an electric bed, a smart television, etc., and can also be used in medical instruments, registration machines, etc.
[0043] Compared with the prior art, the present disclosure has at least the following advantages:
[0044] The double-head power adapter 10 has a commercial power plug 121 and a backup power plug 122, wherein the commercial power plug 121 is used to connect to commercial power, and the backup power plug 122 is used to connect to a battery pack. In general, the double-head power adapter 10 selects commercial power to supply power to the device, and when the commercial power is suddenly cut off, the double-head power adapter 10 has no commercial power input, so the battery pack is used to supply power to the device. From the time when the commercial power is cut off to the time when the battery pack supplies power, the device is always powered on. For some devices that rely on continuous power supply to maintain functions or data integrity, such as medical instruments, it is more friendly. In this way, when the commercial power is cut off, the battery pack immediately supplies continuous power to the device, so the convenience of switching power supply is good.
[0045] The above-described embodiments only express several embodiments of the present disclosure, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the disclosed patent. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present disclosure, several modifications and improvements can be made, which belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent should be subject to the appended claims.
