DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the present application is further described below in conjunction with specific embodiments.

[0021] As shown in Figures 1 to 7 The present application provides a vehicle-mounted air pump with alcohol detector, which mainly consists of front cover mechanism 1, rear cover 2, circuit board mechanism 3, air charging mechanism 4 and battery 5. The front cover mechanism 1 and the rear cover 2 are combined to form the equipment shell by detachable means such as bolt connection. The circuit board mechanism 3, the air charging mechanism 4 and the battery 5 are arranged in sequence inside the shell. The structure is compact and the layout is reasonable, which is convenient for carrying and using. The front cover plate 11 and the rear cover 2 can be connected and fixed by four M3 bolts at the corresponding screw holes in the four corners. The joint surface is provided with a ring-shaped sealing rubber strip to ensure the overall sealing of the shell and prevent dust and water vapor from entering to affect the internal components.

[0022] The front cover mechanism 1 includes a front cover plate 11, which is provided with a display screen plate 12, a plurality of button holes 13 and an alcohol test blowing hole one 15 on the front surface. The button holes 13 are embedded with rubber control buttons 14 for user operation. The display screen plate 12 is arranged below the buttons to facilitate the user to observe the display content while performing control operation. The alcohol test blowing hole one 15 is located at the top of the front cover plate 11 and is a semicircular hole structure for guiding the user to blow air.

[0023] The rear cover 2 corresponds to the front cover mechanism 1 and is provided with an alcohol test blowing hole two 21 at the top and a plurality of air outlet holes 22 at the back. When the front cover plate 11 and the rear cover 2 are combined, the alcohol test blowing hole one 15 and the alcohol test blowing hole two 21 are connected to form a complete circular air blowing channel. The air outlet holes 22 are used to exhaust the air blown by the user to keep the air flow unobstructed.

[0024] The circuit board mechanism 3 is fixed inside the front cover mechanism 1 and includes a circuit board body 31 and various functional modules arranged thereon.

[0025] On the front side of the circuit board body 31, there are, in sequence, an alcohol and air pump display screen 32, an alcohol and air pump power supply master switch 33 and a display switch 34. The alcohol and air pump display screen 32 is used to display the alcohol concentration value and the air pressure data in real time. The alcohol and air pump power supply master switch 33 controls the power supply of the entire device. The display switch 34 is used to turn on or off the backlight or display content of the display screen.

[0026] On the top of the rear side of the circuit board body 31, there are, in sequence, a charging port 311, a display lamp 312, a USB interface 313, a buzzer 314 and an alcohol sensor 315. The charging port 311 is preferably a Type-C interface, which is connected to the battery 5 through a battery connecting line 317 for charging the battery. The USB interface 313 can be used for data transmission or external power supply. The alcohol sensor 315 is located in the air blowing channel composed of the alcohol test air blowing hole one 15 and the alcohol test air blowing hole two 21, and is used to detect the alcohol concentration in the air blown by the user. The buzzer 314 and the display lamp 312 are signal connected with the alcohol sensor 315, and when the alcohol concentration exceeds the set threshold value, the buzzer 314 sounds and the display lamp 312 flashes to remind the user to pay attention; The alcohol sensor 315 is vertically installed on the circuit board body 31 through a fixed bracket with an opening, and its sensing surface is opposite to and close to the central axis of the air blowing channel. The inner wall of the air blowing channel is smooth, which guides the air flow blown by the user to pass through the sensor sensing area, ensuring the detection accuracy. The alcohol concentration threshold value is 20mg / 100ml by default, and can be adjusted according to the internal program of each country's regulations. When the detection value exceeds the threshold value, the buzzer 314 sounds, the display lamp 312 flashes, and the air pump display screen 32 displays a warning message. The user can enter the calibration mode by simultaneously pressing the alcohol and air pump power supply master switch 33 and the display switch 34 for three seconds.

[0027] On the bottom of the rear side of the circuit board body 31, there are a motor connecting line 316 and a battery connecting line 317. The battery connecting line 317 is connected to the battery 5 to realize the functions of power supply and charging. The motor connecting line 316 is connected to the motor 41 of the air charging mechanism 4 to control the start and stop and operation of the air charging mechanism. The circuit board body 31 is integrated with a motor drive chip and a control unit. After the user long-presses the air charging rubber control button 14, the control unit receives the signal and controls the motor 41 to start through the motor drive chip. At the same time, the circuit board body 31 receives the feedback signal from the air pressure sensor integrated at the air cylinder 43 or the cylinder cover 47, adjusts the motor speed in real time, and automatically stops when the preset air pressure is reached, realizing constant pressure air charging.

[0028] The inflation mechanism 4 is located inside the rear cover 2 and is set on one side of the circuit board mechanism 3. It mainly includes a motor 41, a cylinder bracket 42, a cylinder 43, a drive gear 44, a driven gear 45, a connecting rod 46, and a cylinder head 47.

[0029] The motor 41 is fixed by the cylinder bracket 42, and its output shaft is connected to the drive gear 44. The drive gear 44 meshes with the driven gear 45 to form a gear transmission pair. The eccentric position of the driven gear 45 is movably connected to the piston in the cylinder 43 through the connecting rod 46. When the motor 41 works, it drives the drive gear 44 to rotate, which drives the driven gear 45 to rotate, and then pushes the piston to reciprocate in the cylinder 43 through the connecting rod 46 to realize the intake and compression of gas. The cylinder wall of cylinder 43 is equipped with an intake valve and an exhaust valve. When the piston reciprocates, the intake valve opens during the intake stroke to draw in external air; it closes during the compression stroke and the exhaust valve opens to output compressed air through cylinder head 47 to the charging pipe. Both the intake valve and the exhaust valve are one-way diaphragm structures to ensure unidirectional gas flow.

[0030] The top of cylinder 43 is connected to cylinder head 47, which extends to the outside of the equipment housing and is used to connect an inflation hose to supply air to tires or other inflatable objects.

[0031] To improve stability and lifespan, a shock-absorbing pad 48 is provided at the bottom of the motor 41 for vibration reduction and noise reduction; a fan blade 49 is also installed below the motor 41 to generate airflow as the motor rotates, which actively dissipates heat from the motor.

[0032] The battery 5 is located on one side of the inflation mechanism 4 and is connected to the circuit board mechanism 3 via the battery connection line 317. It provides power to the circuit board mechanism 3 and the inflation mechanism 4. The battery 5 is preferably a rechargeable lithium battery, which can be charged through the charging port 311 and supports long-term battery life.

[0033] The working principle of this vehicle-mounted air pump with built-in alcohol detector will be explained in detail below.

[0034] like Figures 1-7 As shown, when using the device, the user first turns on the main power switch 33 for the alcohol and air pump, and the device is powered on and started. If an alcohol self-test is required, the user blows air into the air outlet consisting of alcohol test air inlet 15 and alcohol test air inlet 21. The gas is detected by the alcohol sensor 315, and the test result is displayed in real time on the alcohol and air pump display screen 32. If the alcohol concentration exceeds the standard, the buzzer 314 sounds and the indicator light 312 flashes, issuing an alarm. If tire inflation is required, the user connects the inflation hose to the cylinder head 47 and starts the inflation mode through the rubber control button 14. The motor 41 works, driving the inflation mechanism 4 to run. The air pressure data is displayed in real time on the air pump display screen 32. The user can control the inflation process according to the displayed data and stop after reaching the required pressure.

[0035] Variations of embodiments On the basis of the basic structure of the present application, those skilled in the art can make appropriate variations according to actual needs. For example, the type of alcohol sensor 315 can be selected as an electrochemical type or a semiconductor type; the display screen 32 of the air pump can be made of LCD or OLED material; the specific transmission mode of the inflating mechanism 4 can also use other connecting rods or crankshaft structures; the shell shape, button layout, interface type, etc. can be adjusted according to design requirements, and these changes should be considered to fall within the protection scope of the present application.

[0036] The above shows and describes the basic principles and main features of the present application and the advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application.
