Description

Technical Field

[0001] The present invention relates to the technical field of electric pumping, and in particular to an electric pumping device. Background Art

[0002] The air pump drives the airbag assembly to move through the motor to achieve the purpose of inhaling or exhausting air. However, the existing air pump has a complex structure, a large number of parts, and a cumbersome assembly process, resulting in low assembly efficiency. Therefore, it is necessary to provide a more optimized design solution to meet market demand.

[0003] At present, the electric air pump for inflating tires or other inflatable objects is mainly composed of an air pump in an outer shell and a battery for providing power to the air pump, and a control switch assembly is provided to connect the air pump and the battery. The control switch assembly has a power switch and an air pump operation button light exposed outside the outer shell, wherein the power switch controls whether the power is turned on or not, and the air pump operation button is used to start or stop the air pump. A connecting pipe assembly is installed on the outside of the outer shell, and one end of the pipe of the connecting pipe assembly is provided with an air pump joint, and the other end passes through the shell and is connected to the air outlet end of the air pump.

[0004] When the existing electric air pump is used, after connecting the air valve of the tire or the air nozzle of the object to be inflated with the air pump connector at the end of the connecting assembly, first switch the power switch to the on position, then start the air pump via the air pump operation button, and stop the air pump via the air pump operation button after the tire or the object to be inflated is completely inflated, and detach the air pump connector of the connecting assembly from the air valve of the tire or the air nozzle of the object to be inflated. When the electric air pump is not in use, switch the power switch to the off position and then put away the connecting assembly.

[0005] Although the existing electric pumping device can provide a labor-saving tool for inflating tires or objects to be inflated, the independent power switch and the inflation operation button of the electric pumping device need to be switched separately, which is inconvenient to use. When the electric pumping device is not in use, the user often forgets to switch the power switch to the off position.

[0033] like Figures 1 to 4 The electric pumping device of the present invention includes a housing 10 , a control assembly 20 , an air pump 30 and a pipe assembly 40 .

[0034] like Figures 1 to 4 As shown, the shell 10 is a hollow component with an accommodating space inside. The shell has a front face 11. The shell 10 has a pipe assembly side wall 12 adjacent to the front face 11. The pipe assembly side wall 12 is provided with a pivot hole 121. The pivot hole 121 is a through hole on the outer surface of the pipe assembly side wall 12 that penetrates inwardly and connects to the accommodating space. The outer surface of the pipe assembly side wall 12 can also be provided with a switch position mark 122, such as ON / OFF, on the periphery of the pivot hole 121, and a rotation direction mark 123, such as an arrow, can be further added.

[0035] like Figures 1 to 4 As shown, in a preferred embodiment, the two opposite ends (front end and rear end) of the housing 10 in the length direction are the front end wall 14 and the rear end wall 15. The pivot hole 121 is provided near the front end of the pipe assembly side wall 12, and the pipe assembly side wall 12 may also be provided with a clamping member 13 near the rear end to clamp and fix the pipe assembly 40.

[0036] like Figures 1 to 4 As shown, the housing 10 can be a plurality of parts relatively assembled and fixed by screw locking or clamping, etc. In a preferred embodiment, the housing 10 includes an upper half shell part 101 and a lower half shell part 102 relatively assembled up and down and fixed by a plurality of screws.

[0037] In addition, the housing 10 is provided with heat dissipation holes 141, 151 on one or both of the front wall 14 and the rear wall 15 for ventilation and heat dissipation. A fan 16 can be additionally provided inside the housing 10 near the front wall 14 having the heat dissipation holes 141, 151, and the fan 16 can be electrically connected to the control component 20 for powering on and assisting in heat dissipation.

[0038] like Figures 1 to 4 As shown, the control component 20 is installed in the housing 10. The control component 20 includes a control circuit board 21 with a control circuit, a power switch element 22 and a display panel 23. The control circuit board 21 is installed inside the housing 10. The power switch element 22 is adjacent to the pivot hole 121 and is electrically connected to the control circuit board 21. The power switch element 22 is used to control whether the power is turned on or not. The power switch element 22 can be a contact switch element or a sensing switch element. Both the contact switch element and the sensing switch element can use existing electronic components, and their specific structures are not repeated. The display panel 23 is exposed on the front side 11 of the housing 10 and is electrically connected to the control circuit board 21. The display panel 23 has a display function of the switch state or the use state (such as the air pressure value). In a preferred embodiment, the control component 20 is installed at the front end position adjacent to the front side 11 inside the housing 10.

[0039] like Figures 1 to 4 As shown, the display panel 23 of the control component 20 can be a touch display panel, which has control functions such as operation and setting, or the display panel 23 is a display panel with a simple display function. The control component 20 has at least one button 24, which is exposed on the front side of the shell 10 and is electrically connected to the control circuit board 21. The button 24 performs control functions such as operation and setting.

[0040] like Figure 3 to Figure 4 As shown, the air pump 30 is installed in the shell 10 and electrically connected to the control component 20. The air pump 30 has the function of controlled pressurized air output, and the air pump 30 includes an air outlet end 31, and the position of the air outlet end 31 corresponds to the position of the pivot hole 121.

[0041] like Figures 1 to 4 As shown, the pipe assembly 40 is rotatably arranged on the pipe assembly side wall 12 of the housing 10. The pipe assembly 40 includes an air pump pipe 41, a connecting component 42 and an air pump connector 43. The air pump pipe 41 is a flexible hose. The connecting component 42 and the air pump connector 43 are respectively assembled at both ends of the air pump pipe 41. The connecting component 42 can rotatably pass through the pivot hole 121 of the housing 10 and is airtightly connected to the air outlet end 31 of the air pump 30. The connecting component 42 has a switch operating part 421, which is located in the housing 10 and corresponds to the position of the power switch element 22. The switch operating part 421 changes the power switch state of the power switch element 22 as the pipe assembly 40 rotates relative to the housing 10.

[0042] In this embodiment, the connecting pipe assembly can automatically switch to the power-on state when it is rotated toward the front end of the shell, and automatically switch to the power-off state when the connecting pipe assembly is rotated backward to the folded position on one side of the shell, thereby improving the convenience of using the electric air pump.

[0043] like Figures 1 to 4As shown, in a preferred embodiment, the power switch element 22 is a normally closed contact power switch element 22, and includes a contact portion 221. When the contact portion 221 is pressed, the power switch element 22 is in an "off" state, and when the contact portion 221 is not pressed, the power switch element 22 is in an "on" state. Therefore, when the pipe assembly 40 rotates and retracts to the side of the pipe assembly side wall 12 of the housing 10, the switch operating portion 421 can contact and press the contact portion 221 of the power switch element 22, so that the power switch element 22 is in an off state. When the pipe assembly 40 rotates away from the pipe assembly side wall 12 of the housing 10 to the front end of the housing 10, the switch operating portion 421 is separated from the contact portion 221 of the power switch element 22, so that the contact portion 221 pops open and the power switch element 22 is switched to an on state. As mentioned above, the switch operating part 421 can be a fan-shaped sheet with an angle less than or equal to 100 degrees, so that when the connecting pipe assembly 40 is rotated at an angle greater than 100 degrees, the switch operating part 421 is separated from the contact part 221 of the power switch element 22. In a preferred embodiment, the switch operating part 421 is a fan-shaped sheet with an angle of 90 degrees.

[0044] In addition, when the power switch element is a sensing power switch element (not shown in the figure), the sensing power switch element can be used to sense the position of the switch operating part to change its switch state, which will not be repeated here.

[0045] As mentioned above, the electric pumping device of the present invention can use a direct external power supply to perform the pumping function. Alternatively, the electric pumping device can also be equipped with a power storage component, wherein the housing is provided with a battery connection component (not shown in the figure) that is electrically connected to the control component and can accommodate the battery in its accommodating space, and a detachable outer cover is provided at the position of the housing corresponding to the battery connection component, and the battery connection component can be disassembled and installed to provide the electric energy required for the electric pumping device when in use. Alternatively, Figure 3 to Figure 4 As shown, a power storage component 50 with charging and discharging functions may also be provided at the rear end of the accommodation space inside the housing 10, and the power storage component 50 is electrically connected to the control component 20. In a preferred embodiment, a charging connection element 25 may also be provided on the control circuit board 21 of the control component 20, and the charging connection element 25 is exposed outside the housing 10. The charging connection element 25 can be connected to an external charging wire group to connect to an external power source to charge the power storage component 50. The housing 10 may also be provided with a cover plate 17 at a position corresponding to the charging connection element 25 to provide dustproof and waterproof purposes.

[0046] like Figure 3 to Figure 4As shown, in the aforementioned electric air pump device, preferably, the shell 10 is a long strip-shaped component, such as a rectangular parallelepiped; the air pump 30 and the control component 20 are arranged side by side at the front end position inside the shell 10, and a protective cover 32 can be set between the air pump 30 and the control component 20. The air pump 30 and the control component 20 are isolated by the protective cover 32, and the battery connection component or the power storage component 50 can be set at the rear end position inside the shell 10, thereby preferably configuring the space so that the internal space of the shell 10 can be fully utilized.

[0047] In this embodiment, the shell is a long hollow component, the air pump and the control component are arranged side by side at the front end position inside the shell, the connecting pipe component is pivotally connected to the front end of the connecting pipe assembly side of the shell, and the power storage component is installed at the rear position inside the shell. The combination structure of the components located inside the shell in a straight line along the length direction of the shell enables the electric air pump to achieve better spatial layout compactness.

[0048] like Figure 1 and Figure 5 As shown, the electric pumping device of the present invention is in the folded state, the pipe assembly 40 is located outside the pipe assembly side wall 12 of the housing 10, and the length of the pipe assembly 40 is equal to or not much different from the length of the housing 10, so that the electric pumping device has a smaller product volume after being folded, which is convenient for carrying and collection. In addition, when the pipe assembly is in the folded state, the switch operating part 421 of the connecting part 42 of the pipe assembly 40 is separated from the power switch element 22, and the power is turned off.

[0049] In this embodiment, the connecting pipe assembly can also be folded to one side of the shell and is equal to the length of the shell, so that the electric air pump can effectively reduce the overall volume of the product for easy carrying, use and storage.

[0050] When a user wants to use the electric pumping device of the present invention to inflate a tire or other inflatable object of a vehicle, Figures 5 to 7As shown, the user rotates the connecting pipe assembly 40 forward from the connecting pipe assembly side wall 12 of the shell 10. At this time, the switch operating part 421 of the connecting part 42 of the connecting pipe assembly 40 rotates toward the contact part 221 of the power switch element 22, and the power switch element 22 automatically switches to the power-on state, so that the control component 20 turns on the power storage component 50, and the user can connect the tire valve or the air nozzle of the inflatable object with the inflation connector 43 of the connecting pipe assembly 40. After that, the user can control the operation of the air pump 30 through the button or touch display panel of the control component 20, so that the pressurized air output by the air pump 30 passes through the connecting pipe assembly 40 to the tire or the inflatable object. After the inflation is completed, remove the connecting pipe assembly 40, rotate the connecting pipe assembly 40 backward to the folded position of the connecting pipe assembly side wall 12 of the shell 10, and automatically switch to the power-off state by disengaging the switch operating part 421 of the connecting part 42 of the connecting pipe assembly 40 from the power switch element 22.

[0051] The electric air pump provided by the present invention realizes the opening and closing of the power switch element by rotating the connecting pipe assembly, so that the power is turned on when the electric air pump is in the working state and the power is turned off when the electric air pump is in the non-working state, without the need for special power on or off operations.

[0052] Furthermore, the electric pumping device of the present invention has a compact overall structure, which reduces the size of the product and is easy to carry and store.

[0053] The methods disclosed in the several method embodiments provided by the present invention can be arbitrarily combined without conflict to obtain new method embodiments.

[0054] The features disclosed in several product embodiments provided in this application can be arbitrarily combined without conflict to obtain new product embodiments.
