Technical Field

[0001] This application relates to the field of venting valve technology, specifically to a venting valve. Background Technology

[0002] A tire deflation valve is used to control the reduction of tire pressure to adapt to different usage scenarios and ensure driving safety and tire performance. Patent application number 201721257468.4 discloses a deflation valve, particularly for use in an electronically controlled tire blowout avoidance system. This deflation valve includes a valve body and a valve core; the valve body secures the valve to the tire and facilitates the installation of the valve core; the valve body has a notch; the valve core is a hollow structure with a deflation channel, rotatably fitted inside the valve body, and a destructive plate is located on the valve core body relative to the notch; the deflation valve also includes a heat-sealed plastic sleeve, which simultaneously seals the notch and the destructive plate, forming a destructive sealing structure. This deflation valve can only perform a single deflation function and cannot detect tire pressure or provide precise deflation values, requiring a tire pressure monitoring system, making its use inconvenient.

[0028] Combination Figures 1-7 As shown, this application provides a bleed valve, including a housing 1 and a valve core assembly installed in the housing 1. The valve core assembly includes a connecting pipe 2 and a valve core 3 movably installed in the connecting pipe 2. A drive mechanism is installed at one end of the housing 1 of the valve core assembly. The drive mechanism includes a motor 4 and a drive block 5. The drive block 5 is located at one end of the valve core 3, that is, the drive block 5 can push the valve core 3 to one side to push it out from the opening of the connecting pipe 2 to release air. A circuit board 6 is also provided inside the housing 1. The circuit board 6 can control the operation of the motor 4. At the same time, the circuit board 6 has a pressure sensor that can measure the real-time tire pressure of the external tire. By setting the required tire pressure value, the motor 4 is controlled to operate. The rotation of the motor 4 drives the drive block 5 to push out the valve core 3 to release air, so that the external tire pressure is reduced to the set threshold.

[0029] In some embodiments, such as Figures 4-6 As shown, a movable groove 7 is provided through the connecting pipe 2. The valve core 3 is set in the movable groove 7 and its end can pass through the movable groove 7. The valve core 3 is provided with a flange 8. A stop ring 9 is provided in the movable groove 7. A spring 10 is installed between the stop ring 9 and the flange 8. The spring 10 plays a buffering role. When the valve core assembly is connected to the external tire, the spring 10 is compressed. In this embodiment, the drive mechanism also includes a planetary gear set 11. The motor 4 is connected to the drive block 5 through the planetary gear set 11 and the worm gear 12. The drive gear of the motor 4 is connected to the planetary gear set 11. When the motor 4 rotates, it drives the planetary gear set 11 to rotate as a whole through the drive gear. The end of the planetary gear set 11 is provided with a worm gear 12. The worm gear 12 cooperates with the worm groove inside the drive block 5. When the worm gear 12 rotates, it drives the drive block 5 to move laterally. The end of the drive block 5 is provided with a drive column 13. The drive column 13 is located at one end of the valve core 3. When the drive block 5 moves laterally, it pushes out the valve core 3 through the drive column 13.

[0030] In some embodiments, such as Figure 6 and Figure 7 As shown, the housing 1 is provided with multiple positioning posts 14. The circuit board 6 is fixed in the housing 1 by the positioning posts 14. The positioning posts 14 are provided with mounting grooves 15. The drive mechanism is placed in the mounting grooves 15. The valve core 3 is located on one side of the drive mechanism and is fitted with multiple sealing rings 16. The sealing rings 16 are attached to the inner wall of the movable groove 7 to achieve airtightness. One end of the connecting pipe 2 is provided with a threaded part 17. The housing 1 is provided with a corresponding threaded groove 18. The connecting pipe 2 is threadedly connected to the housing 1.

[0031] In some embodiments, such as Figure 1 and Figure 2As shown, a battery 19 is also installed inside the housing 1. The surface of the circuit board 6 is provided with a display screen 20 and multiple control keys 21. The display screen 20 and control keys 21 pass through the housing 1. The control keys 21 can be used to directly control the deflation valve to set the value and operate. When the air pressure value is set, the motor 4 will drive the valve core 3 to quickly deflate to a certain air pressure and then stop. The pressure sensor on the circuit board 6 will detect the tire pressure and continue deflation after measuring the value. The above steps are repeated multiple times until the set pressure value is reached and the deflation valve stops working. The greater the difference between the tire pressure and the set deflation pressure, the faster the motor 4 runs and the faster the deflation speed. When the pressure difference gradually decreases, the deflation speed gradually decreases.

In particular, the descriptions of the embodiments described later are relatively simple, and relevant parts can be referred to the descriptions of the foregoing embodiments.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application.
