[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Refer to the attached Figure 1-8 , an air pump 100 in an embodiment of the present invention.

[0039] The air pump 100 includes a main body 1 and a control module 10, a pump body 7, a battery 6, a stepless adjustment member 24 and a switch 23 arranged on the main body 1. The control module 10 is electrically connected to the battery 6, the pump body 7, the stepless adjustment member 24 and the switch 23 respectively. The control module 10 is preset with multiple different power ranges for driving the inflation type of the pump body 7. The switch 23 is used for user operation and transmits a switching signal to the control module 10. The stepless adjustment member 24 is used for user operation and transmits a stepless adjustment signal to the control module 10. The control module 10 switches the inflation type according to the switching signal and outputs the preset power corresponding to the inflation type to the pump body 7. The control module 10 also adjusts the driving power output to the pump body 7 within the power range corresponding to the inflation type according to the stepless adjustment signal.

[0040] This embodiment configures multiple inflation types with different power ranges within the control module 10, and configures a switch 23 so that the user can switch the inflation type to adapt to the inflation of various types of products. This effectively expands the product applicability of the air pump 100 and overcomes the problem that the existing air pump 100 can only charge one type of product. Furthermore, this embodiment configures a stepless adjustment member 24 so that the user can adjust the power range of the inflation type through the stepless adjustment member 24, so that the control module 10 increases or decreases the driving power output to the pump body 7 to increase the inflation rate and enhance the user's experience of using the air pump 100.

[0041] It should be noted that different power drives the pump body 7 to work, allowing the pump body 7 to output different air pressures. Based on this, the control module 10 can configure the power range of the driving pump body 7 according to the air pressure range required to be output by the pump body 7.

[0042] Specifically, the multiple inflation types may include inflating a basketball, inflating a car tire, inflating a bicycle tire, inflating a motorcycle tire, and custom inflation, etc. The pressure range for inflating a basketball can be preset to 4-16 PSI, the pressure range for inflating a bicycle tire can be preset to 30-120 PSI, the pressure range for inflating a motorcycle tire can be preset to 26-44 PSI, the pressure range for inflating a car tire can be preset to 26-51 PSI, and the pressure range for custom inflation can be preset to 3-150 PSI. Accordingly, the control module 10 configures a corresponding power range according to the inflation type to drive the pump body 7 to work, so that the pump body 7 outputs the corresponding air pressure.

[0043] When the control module 10 switches the inflation type to inflating a basketball, and the stepless adjustment member 24 is used to adjust the output air pressure of the pump body 7, the adjustable air pressure range is limited to 4-16 PSI. Based on the factory settings, when the control module 10 switches the inflation type to inflating a basketball, and the user provides the air pump 100 of this embodiment to inflate, when the air pressure is not adjusted through the stepless adjustment member 24, the default output air pressure is 8 PSI.

[0044] When the control module 10 switches the inflation type to inflating a bicycle tire, and uses the stepless adjustment member 24 to adjust the output air pressure of the pump body 7, the adjustable air pressure range is limited to 30-120PSI. Based on the factory settings, when the control module 10 switches the inflation type to inflating a bicycle tire, and the user provides the air pump 100 of this embodiment for inflation, when the air pressure is not adjusted through the stepless adjustment member 24, the default output air pressure is 45PSI.

[0045] When the control module 10 switches the inflation type to inflating motorcycle tires, and uses the stepless adjustment component 24 to adjust the output air pressure of the pump body 7, the adjustable air pressure range is limited to 26-44PSI, and based on the factory settings, when the control module 10 switches the inflation type to inflating motorcycle tires, and the user provides the air pump 100 of this embodiment for inflation, when the air pressure is not adjusted through the stepless adjustment component 24, the default output air pressure is 35PSI.

[0046] When the control module 10 switches the inflation type to inflating the car tire, when the stepless adjustment component 24 is used to adjust the output air pressure of the pump body 7, the adjustable air pressure range is limited to 26-51PSI, and based on the factory settings, when the control module 10 switches the inflation type to inflating the car tire, and the user provides the air pump 100 of this embodiment for inflation, when the air pressure is not adjusted through the stepless adjustment component 24, the default output air pressure is 36PSI.

[0047] That is, when the control module 10 switches the inflation type to custom inflation, when the stepless adjustment component 24 is used to adjust the output air pressure of the pump body 7, the adjustable air pressure range is limited to 3-150PSI, and based on the factory settings, when the control module 10 switches the inflation type to custom inflation, and the user provides the air pump 100 of this embodiment to inflate, when the air pressure is not adjusted through the stepless adjustment component 24, the default output air pressure is 30PSI.

[0048] Of course, in other embodiments, the air pressure range for bicycle tire inflation may be preset to 20-100 PSI, the air pressure range for motorcycle tire inflation may be preset to 20-40 PSI, and the air pressure range for automobile tire inflation may be preset to 20-45 PSI, etc. The air pressure ranges for bicycle tire inflation, motorcycle tire inflation, automobile tire inflation, and ball inflation, etc., may be customized by the manufacturer or in subsequent program upgrades. The air pressures for basketball inflation, automobile tire inflation, bicycle tire inflation, motorcycle tire inflation, and customized inflation are not limited herein.

[0049] In one embodiment, the stepless adjustment member 24 may be a digital encoder. Specifically, when the knob of the digital encoder is turned, two changing electrical signals (i.e., stepless adjustment signals) may be output to the control module 10. The control module 10 adjusts the driving power output to the pump body 7 according to the changing electrical signals.

[0050] In one embodiment, the stepless adjustment member 24 can also be a rotary potentiometer, that is, when the knob on the rotary potentiometer is turned, the resistance value of the rotary potentiometer can be adjusted. Based on different resistance values, the rotary potentiometer can feedback different voltage signals (that is, stepless adjustment signals) to the control module 10, and the control module 10 adjusts the driving power output to the pump body 7 within the power range according to the voltage signal.

[0051] Specifically, when the stepless adjustment member 24 can be a digital encoder or a rotary potentiometer, a roller 3 is provided on the main body 1, and the roller 3 is connected to the knob on the digital encoder or the rotary potentiometer. When the user rotates the roller 3, the stepless adjustment member 24 outputs a stepless adjustment signal to the control module 10. Based on this signal, the control module 10 adjusts the driving power output to the pump body 7. The use of the roller 3 can facilitate user operation.

[0052] In one embodiment, the stepless adjustment member 24 may also be a sliding potentiometer. A sliding member is slidably provided on the main body 1 and connected to the sliding potentiometer. When a user slides the sliding member, the sliding potentiometer outputs a stepless adjustment signal to the control module 10. Specifically, when the user slides the sliding member, the resistance value of the resistor connected to the control module 10 changes. That is, based on the different resistance values, the rotary potentiometer can feedback different voltage signals (i.e., stepless adjustment signals) to the control module 10. The control module 10 adjusts the driving power output to the pump body 7 within the power range according to the voltage signal.

[0053] In the above embodiment, the control module 10 includes an MCU 101 and a power regulating unit 102. The switch 23, the stepless regulating member 24, the battery 6, and the power regulating unit 102 are all electrically connected to the MCU 101, and the power regulating unit 102 is electrically connected to the pump body 7. Multiple inflation types are set in the MCU 101. The MCU 101 is used to receive the stepless regulation signal and generate a drive signal corresponding to the stepless regulation signal. The power regulating unit 102 is used to receive the drive signal and adjust the drive power output to the pump body 7 to output the drive power corresponding to the inflation type to the pump body 7.

[0054] Specifically, the power regulation unit 102 includes a switch 1021. The drain of the switch 1021 is electrically connected to the negative electrode of the pump body 7. The source of the switch 1021 is grounded. The gate of the switch 1021 is electrically connected to the MCU 101. The positive electrode of the battery 6 is electrically connected to the positive electrode of the pump body 7. The switch 1021 is turned on according to the drive signal output by the MCU 101 and adjusts its conduction rate according to the drive signal to adjust the drive power output to the pump body 7. The conduction duty cycle of the switch 1021 is used to adjust the voltage output to the pump body 7, thereby adjusting the power output to the pump body 7.

[0055] Of course, in other embodiments, the power regulation unit 102 may also include multiple switch tubes 1021, resistors and other components, such as Figure 8 As shown, the CN3 interface is used to connect the pump body 7.

[0056] In one embodiment, the air pump 100 further includes a pressure sensor 20 disposed on the main body 1. The pressure sensor 20 is located at the output end of the pump body 7. The pressure sensor 20 is electrically connected to the control module 10, that is, the pressure sensor 20 is electrically connected to the MCU 101. The pressure sensor 20 is used to detect the air pressure output by the main body and feedback a pressure signal corresponding to the air pressure to the control module 10. The control module 10 adjusts the driving power output to the pump body 7 based on the pressure signal. The pressure sensor 20 is used to detect the air pressure output by the pump body 7 in real time and feedback an electrical signal corresponding to the air pressure to the MCU 101. The MCU 101 outputs driving power to the pump body 7 based on the electrical signal, so that the pump body 7 can output a constant air pressure, stabilizing the output air pressure at a certain value.

[0057] In one embodiment, the air pump 100 further includes a display 21 disposed on the main body 1. The display 21 is configured to display at least one or more of the output air pressure and the battery 6 charge level. The display 21 allows the user to understand the battery 6 charge level and the output air pressure, thereby facilitating user use. Specifically, the display 21 may be a digital display 21 or a display screen.

[0058] In one embodiment, the air pump 100 further includes a lighting module 8 for illumination. The lighting module 8 is disposed on the main body 1, and the control module 10 is electrically connected to the lighting module 8. The lighting module 8 provides the air pump 100 with an illumination function for use when required by the user, thereby improving the practicality of the air pump 100 of this embodiment.

[0059] Specifically, the lighting module 8 includes a light board 81 disposed within the main body 1 and a lighting lamp 82 disposed on the light board 81. The light board 81 is electrically connected to the control module 10. The light board 81 is located at the top of the pump body 7. The top of the main body 1 is provided with a lighting opening 1232 at a position corresponding to the lighting lamp 82. The main body 1 is provided with a lampshade 83 at a position corresponding to the lighting opening 1232. The top of the main body 1 is provided with an air outlet interface 71 for connecting to the inflation tube. The air outlet interface 71 is connected to the air outlet of the pump body 7 and is located on one side of the lighting opening 1232 to rationally configure the structure of the air pump 100 of this embodiment. When the pump body 7 outputs air pressure through the air outlet interface 71, the lighting module 8 will not be damaged.

[0060] In one embodiment, the main body 1 is provided with a plurality of air inlet holes 1231 around the periphery of the lampshade 83, and the air outlet port 71 is located on the side of the air inlet holes 1231 away from the illumination opening 1232. The air inlet holes 1231 allow the pump body 7 to take in external air, process it, and then output it at a certain pressure through the air outlet port 71. The air inlet holes 1231 also serve to dissipate heat from the lamp panel 81.

[0061] In the above embodiment, the air pump 100 further includes a lighting switch 29 , and the control module 10 drives the lighting module 8 to illuminate when the lighting switch 29 is operated, so that the user can control the lighting switch 29 to turn on the lighting module 8 when lighting is needed.

[0062] In one embodiment, the main body 1 is provided with a charging port 22 for connecting to an external power source, and the charging port 22 is electrically connected to the control module 10. The battery 6 can be charged via the control module 10 by connecting to an external power source via the charging port 22.

[0063] Specifically, the control module 10 also includes a charge-discharge circuit, which is electrically connected to the charging port 22, the battery 6, the MCU 101, and the power conditioning unit 102. When the charging port 22 is connected to a power source, the battery 6 is charged via the charge-discharge circuit. When the air pump 100 of this embodiment is in use, the battery 6 can supply power to the MCU 101 and the power conditioning unit 102 via the charge-discharge circuit. In embodiments having a lighting module 8, the charge-discharge circuit is also electrically connected to the lighting module 8 to supply power to the lighting module 8; alternatively, if the MCU 101 can directly drive the lighting module 8, the charge-discharge circuit may not be electrically connected to the lighting module 8.

[0064] In the above embodiment, the air pump 100 also includes a circuit board 2, and the control module 10, the stepless adjustment member 24 and the switching switch 23 are all integrated on the circuit board 2. The circuit board 2 is arranged in the main body 1 to simplify the components of the air pump 100 of this embodiment and facilitate the production and manufacturing of the air pump 100.

[0065] In one embodiment, the main body 1 includes an intermediate housing 12 and an outer cover 11. The intermediate housing defines a first cavity 124 and a second cavity 125. The pump body 7 is disposed within the first cavity 124, and the battery 6 is disposed within the second cavity 125. The outer cover 11 is sleeved onto the outer side of the intermediate housing 12. A third cavity 1221 is formed between the outer cover 11 and the intermediate housing 12. The circuit board 2 is disposed within the third cavity 1221. The third cavity 1221 communicates with the first cavity 124 and the second cavity 125, respectively, to electrically connect the control module 10 to the pump body 7 and the battery 6. The first cavity 124, the second cavity 125, and the third cavity 1221, respectively, house the pump body 7, the battery 6, and the circuit board 2. This allows the pump body 7, the battery 6, and the circuit board 2 to be mounted on the main body 1, thereby improving the compactness of the structure of the air pump 100 of this embodiment.

[0067] The intermediate housing 12 is provided with a support block 1222 at a position corresponding to the shaft 31. The circuit board 2 is provided with a first clearance opening 26 for circumventing the support block 1222. The air pump 100 also includes a retaining cover 5 and a pressing member 4. The retaining cover 5 is positioned over the outer side of the roller 3 and cooperates with the support block 1222 to retain the roller 3 in position. The retaining cover 5 is provided with a second clearance opening 51 for circumventing the roller 3. The first clearance opening 26 allows the support block 1222 to pass through the circuit board 2, allowing the support block 1222 to cooperate with the retaining cover 5 to retain the shaft 31 on both sides of the roller 3, thereby retaining the roller 3 in position. The second clearance opening 51 exposes the roller 3 for user operation.

[0068] The pressing member 4 is made of a flexible material and is sleeved onto the outer side of the limiting cover 5. A third clearance opening 41 is provided on the pressing member 4 to clear the limiting cover 5, exposing the roller 3. A first limiting edge 52 is provided around the limiting cover 5, while a second limiting edge 42 is provided protruding from the surrounding side of the pressing member 4. The first limiting edge 52 is positioned between the pressing member 4 and the circuit board 2, while the second limiting edge 42 is positioned between the circuit board 2 and the outer cover 11, thereby securing the limiting cover 5 and the pressing member 4.

[0069] The pressing member 4 is provided with a first pressure rod 44 at the position corresponding to the switch 23, for pressing the switch 23. A fourth clearance opening 1120 is provided on the housing 11 to allow the pressing member 4 to pass through, facilitating the user's pressing of the pressing member 4. When the user presses the pressing member 4 at the first pressure rod 44, the pressing member 4, through the first pressure rod 44, presses the switch 23, turning the switch 23 on. This means that the switch 23 feeds back an electrical signal (i.e., a switching signal) to the control module 10, which then switches the inflation type accordingly.

[0070] In one embodiment, a first positioning end 53 is provided on the limiting cover 5, a second positioning end 43 is provided on the pressing member 4, a first positioning hole 28 and a second positioning hole 27 are opened on the circuit board 2, the first positioning end 53 is placed in the first positioning hole 28, and the second positioning end 43 is placed in the second positioning hole 27, thereby improving the installation stability of the limiting cover 5 and the pressing member 4.

[0071] In one embodiment, the circuit board 2 is further provided with a power button 25 electrically connected to the control module 10. The power button 25 and the selector switch 23 are arranged around the periphery of the roller 3.

When a user presses the pressing member 4 at the second pressure rod 46, the second pressure rod 46 can press the power button 25, thereby turning on the power button 25. In other words, the power button 25 feeds back an electrical signal to the control module 10, which then turns on or off based on the signal, allowing the user to subsequently operate the selector switch 23 and the stepless adjustment member 24.

[0072] In the embodiment with the lighting module 8, the air pump 100 further includes the lighting module 8 for lighting. A lighting switch 29 electrically connected to the control module 10 is provided on the circuit board 2. The lighting switch 29 and the switching switch 23 are arranged around the circumference of the roller 3.
