Detailed Implementation

[0026] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0027] like Figure 1-3 As shown, a portable multi-functional travel device includes a housing 10, a circuit board assembly, a rechargeable battery 30, a charging input interface 40, a charging output interface 50, a load cell 60, a weighing rope 70, a display screen 80, a first control button 90, a power interface 100, a miniature vacuum pump 110, an air extraction port 111, an exhaust port 112, and a second control button 120. The circuit board assembly includes a first circuit board 21 and a second circuit board 22.

[0028] The housing 10 is elongated and cylindrical, comprising an upper housing 11 and a lower housing 12, which are detachably connected together. Specifically, magnets 13 are provided at the connection points of the upper housing 11 and the lower housing 12, allowing them to be detachably connected. Furthermore, matching bosses 14 are provided at the connection points of the upper housing 11 and the lower housing 12, which, through their engagement, achieve a limiting and fixing effect between the upper housing 11 and the lower housing 12.

[0029] like Figure 4 , 5As shown, the upper housing 11 houses a first circuit board 21, a rechargeable battery 30, and a load cell 60. The outer wall of the upper housing 11 is equipped with a charging input interface 40, a charging output interface 50, a weighing rope 70, a display screen 80, and a first control button 90. The first circuit board 21 is electrically connected to the rechargeable battery 30, the charging input interface 40, the charging output interface 50, the load cell 60, the display screen 80, and the first control button 90. The first circuit board 21 integrates a main control module, a power management module, a weighing processing module, and a display output module. The first circuit board 21 controls the power supply and charging / discharging of the rechargeable battery 30, receives and processes signals from the load cell 60, and controls the display content of the display screen 80. The rechargeable battery 30 powers the entire device. The charging input interface 40 charges the rechargeable battery 30, and the charging output interface 50 charges other external electronic devices. The load cell 60 is connected to the weighing rope 70, which is used to connect to the object. The load cell 60 measures the weight of the object and converts the weight information into an electrical signal, which is then transmitted to the first circuit board 21. The display screen 80 displays information such as battery level and weight. The first control button 90 controls the on / off switch of the device, the weighing and de-hairing function, and the switching of content on the display screen 80.

[0030] like Figure 6 , 7 As shown, the upper shell 11 has a storage cavity 130 at its rear end, and the weighing rope 70 is disposed in the storage cavity 130. A first cover 131 is closable over the storage cavity 130, concealing the weighing rope 70 within it. When weighing is required, the first cover 131 is opened, and the weighing rope 70 is attached to the item. Specifically, the rear end of the first cover 131 is hinged to the storage cavity 130, and a first elastic element 132 is provided at the hinge to allow the first cover 131 to automatically spring open. The front end of the first cover 131 is closablely engaged with the storage cavity 130 via a snap-fit ​​structure. The latching structure includes an opening / closing button 133, a second elastic element 134, a first latch 135, and a second latch 136. The opening / closing button 133 is disposed on the outer wall of the upper housing 11. The first latch 135 is movably mounted on the storage cavity 130. The second latch 136 is fixed on the first cover 131. The first latch 135 and the second latch 136 engage, thereby allowing the first cover 131 to close over the storage cavity 130. The opening / closing button 133 is connected to the first latch 135 via the second elastic element 134. When the opening / closing button 133 is pressed, the first latch 135 moves and disengages from the second latch 136. At this time, the first cover 131 automatically opens under the action of the first elastic element 132. When the pressure on the opening / closing button 133 is removed, the first latch 135 resets under the action of the second elastic element 134, and the first latch 135 and the second latch 136 re-engage.

[0031] One end of the weighing rope 70 is fixedly connected to the weighing sensor 60, and the other end is a movable end 71. The movable end 71 is detachably connected to the storage cavity 130. When it is necessary to weigh an item, the first cover 131 is opened, and then the movable end 71 of the weighing rope 70 is removed, inserted into the item, and then reconnected to the storage cavity 130, so that the weighing rope 70 forms a loop structure and is tied to the item to prevent the item from loosening during the weighing process. The detachable structure of the movable end 71 of the weighing rope 70 is as follows: the movable end 71 is provided with a slot 72, and the storage cavity 130 is provided with a locking hole 137. The movable end 71 is inserted into the locking hole 137, and a locking block 138 is rotatably provided on the locking hole 137. The locking block 138 engages with the slot 72 of the movable end 71, thereby locking the movable end 71 into the locking hole 137 of the storage cavity 130. The locking block 138 is connected to a third elastic element 139, and the locking block 138 is in contact with the first latch 135. When the opening / closing button 133 is pressed, the first latch 135 pushes the locking block 138 to rotate, causing the locking block 138 to disengage from the slot 72, thereby removing the movable end 71. When the external force on the opening / closing button 133 is removed, the locking block 138 is reset by the elastic force of the third elastic element 139 and re-locks onto the slot 72, thus re-locking the movable end 71. With the above structure, the opening / closing button 133 can be used to simultaneously operate the opening and closing of the first cover 131 and the unlocking of the weighing rope 70. The weighing rope 70 is unlocked at the same time as the first cover 131 is opened, making the operation simple and convenient.

[0032] It also includes an interface adapter 140, which can be connected to the charging output interface 50 to adapt to different electronic device interfaces. The upper housing 11 is provided with an interface slot 15, and both the charging output interface 50 and the interface adapter 140 can be detachably snapped into the interface slot 15.

[0033] like Figure 8-10 As shown, the lower housing 12 houses a second circuit board 22 and a miniature vacuum pump 110. The outer wall of the lower housing 12 has an air extraction port 111, an exhaust port 112, and a second control button 120. The second circuit board 22 is electrically connected to the miniature vacuum pump 110 and integrates a vacuum pump control module for controlling the start and stop of the miniature vacuum pump 110. The miniature vacuum pump 110 is connected to both the air extraction port 111 and the exhaust port 112. The air extraction port 111 is used to evacuate the vacuum bag, and the exhaust port 112 is used to inflate the inflation device. An air nozzle 113 is also included, which is detachably mounted on the outer wall of the lower housing 12. The air nozzle 113 can be installed on either the air extraction port 111 or the exhaust port 112 as needed for air extraction or exhaust operations. The second control button 120 is electrically connected to the second circuit board 22 and is used to control the start and stop of the miniature vacuum pump 110.

[0034] An air intake 111 and an exhaust 112 are located at the rear of the lower housing 12. A second cover 150 is detachably fitted onto the rear of the lower housing 12, covering the air intake 111, the exhaust 112, and the air nozzle 113. The second cover 150 conceals the air intake 111, the exhaust 112, and the air nozzle 113, and can be removed when needed.

[0035] Conductive spring pins 16 and 17 are respectively provided at the connection between the upper housing 11 and the lower housing 12. The conductive spring pin 16 in the upper housing 11 is electrically connected to the first circuit board 21, and the conductive spring pin 17 in the lower housing 12 is electrically connected to the second circuit board 22. When the upper housing 11 and the lower housing 12 are connected together, the conductive spring pins 16 and 17 are electrically connected together, so that the first circuit board 21 and the second circuit board 22 are electrically connected, thereby enabling the rechargeable battery 30 in the upper housing 11 to power the miniature vacuum pump 110 in the lower housing 12. In addition, the lower housing 12 has a power interface 100, which is electrically connected to the second circuit board 22. When the upper housing 11 and the lower housing 12 are separated, the miniature vacuum pump 110 can be powered independently through the power interface 100 without relying on the rechargeable battery 30 in the upper housing 11.

[0036] This multi-functional travel device integrates a power bank and weighing function in its upper housing 11, and a vacuum pump function in its lower housing 12. It is suitable for various travel scenarios, such as charging mobile phones, weighing luggage, vacuuming bags, and inflating air pillows, offering multiple uses and convenience. The lower housing 12 can be detached when not in use, reducing the device's size and weight, making it easy to carry while charging a mobile phone. When the miniature vacuum pump 110 is needed, the lower housing 12 can be reattached to the upper housing 11. The magnet 13 and the protrusion / concave platform 14 facilitate quick and easy installation of the upper and lower housings, making operation simple and convenient.

[0037] It should be noted that in other embodiments, the housing 10 may not adopt the separate structure of the upper housing 11 and the lower housing 12, that is, all components are centrally located on one housing 10.

[0038] The above-described embodiments are merely illustrative of this utility model. Any equivalent embodiments made by those skilled in the art without departing from the technical features disclosed in this utility model, and without departing from the technical features of this utility model, shall still fall within the scope of the technical features of this utility model.
