Description

Technical Field

[0001] This utility model relates to the field of automotive engine intake control systems, and in particular to a throttle valve that is easy to clean. Background Technology

[0002] During the operation of an internal combustion engine, air enters the combustion chamber through the intake system. The throttle valve, as a key component controlling the amount of air entering the engine, affects the engine's operating state by regulating the flow of air into the engine.

[0003] A traditional throttle valve typically includes a rotatable throttle plate mounted inside the intake manifold. This throttle plate is fixed to a throttle shaft connected to it by screws and is driven by the throttle shaft.

[0004] Because carbon deposits and other sediments easily adhere to the surface of the throttle body plate, it is necessary to clean the throttle body regularly. Cleaning requires completely removing the screws to disassemble the throttle body plate, cleaning it, and then reinstalling and tightening the screws. This cleaning method is cumbersome and inefficient. Therefore, in view of the problems existing in the prior art, this application makes an improvement. Utility Model Content

[0005] This invention proposes a throttle body that is easy to clean, solving the aforementioned problems existing in the use of the prior art.

[0006] The technical solution of this utility model is implemented as follows: a throttle body that is easy to clean includes a throttle body, an air chamber on the throttle body, a throttle shaft that radially passes through the air chamber on the throttle body, and a throttle plate on the throttle shaft. The throttle plate is characterized in that: a rotating shaft is rotatably connected to the center of the throttle plate, scrapers are provided on both the front and rear sides of the throttle plate, the scrapers are attached to the surface of the throttle plate, the middle part of the scraper is fixedly connected to the rotating shaft, and an operating shaft is fixedly connected to one end of the rotating shaft.

[0007] Preferably, a rotating hole is provided at the end of the operating shaft.

[0008] Preferably, the rotating hole is an internal hexagonal hole.

[0009] Preferably, a side scraper is fixedly connected between the two ends of the two scrapers on the front and rear sides of the throttle plate, and the side scraper is attached to the side of the throttle plate.

[0010] Preferably, the throttle shaft has an installation port, the throttle plate is disposed in the installation port, and the throttle shaft has pads on both the left and right ends of the installation port for fitting the front and rear sides of the throttle plate. The throttle shaft also has screws on both the left and right ends of the installation port for passing through the throttle shaft, the pads, and the throttle plate.

[0011] Preferably, the size of the mounting opening is sufficient to allow the scraper blade and side scraper strip to enter.

[0012] Preferably, the operating shaft extends through the throttle body shaft.

[0013] In summary, the beneficial effects of this utility model are as follows:

[0014] 1. This invention features a rotating shaft at the center of the throttle body plate, equipped with a scraper that conforms to the surface of the throttle body plate. This allows users to clean the throttle body plate simply by rotating the shaft, without needing to remove screws or the throttle body plate itself. This design greatly simplifies the cleaning process, improves cleaning efficiency, and reduces maintenance time and costs.

[0015] 2. By opening a rotating hole at the end of the operating shaft, a convenient interface for applying torque is provided to the user, making the rotation operation easier and more precise. Furthermore, the rotating hole is designed as an internal hexagonal hole, allowing the use of standard tools (such as an internal hexagonal wrench) for operation, enhancing compatibility and convenience.

[0016] 3. By fixing a side scraper strip between both ends of the scraper blade, the cleaning coverage can be extended to the side area of ​​the throttle body, thereby more thoroughly removing carbon deposits and other deposits. This design provides a more comprehensive cleaning effect and helps maintain the good working condition of the throttle body.

[0017] 4. By setting pads on both sides of the mounting port on the throttle shaft and fixing the throttle plate with screws, the stability of the structure is maintained.

[0018] 5. The installation opening is large enough to allow the scraper blade and side scraper to enter smoothly, meaning that the scraper blade and side scraper can be placed in the installation opening when not in use, so as not to affect the normal operation of the throttle body.

[0028] The following will refer to the appendix in the embodiments of this utility model. Figure 1-7 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Example:

[0030] like Figures 1 to 7As shown, this utility model discloses a throttle body that is easy to clean, including a throttle body 1, an air chamber 11 on the throttle body 1, a throttle shaft 2 that radially passes through the air chamber 11 on the throttle body 1, a throttle plate 3 on the throttle shaft 2, and the throttle shaft 2 being driven by a motor and gear assembly. The above structures are common knowledge to those skilled in the art, and therefore will not be described in detail. In this utility model, a rotating shaft 4 is rotatably connected to the center of the throttle plate 3, and scraper blades 51 are provided on both the front and rear sides of the throttle plate 3. The scraper blades 51 are attached to the surface of the throttle plate 3, and the middle part of the scraper blades 51 is fixedly connected to the rotating shaft 4. An operating shaft 41 is fixedly connected to one end of the rotating shaft 4. This invention, by setting a rotating shaft 4 at the center of the throttle body plate 3 and equipping it with a scraper 51 that fits against the surface of the throttle body plate 3, allows the user to clean the throttle body plate 3 simply by rotating the operating shaft 41 and scraping off the carbon deposits adhering to the throttle body plate 3 using the scraper 51. Therefore, there is no need to remove the screws 6 or remove the throttle body plate 3. This design greatly simplifies the cleaning process, improves cleaning efficiency, and reduces maintenance time and costs.

[0031] Furthermore, a rotating hole 42 is provided at the end of the operating shaft 41. The rotating hole 42 provides a convenient interface for the user to apply torque, making the rotation operation easier and more precise. In addition, the rotating hole 42 is designed as an internal hexagonal hole, which allows the use of standard tools (such as an internal hexagonal wrench) for operation, enhancing compatibility and convenience.

[0032] To clean the sides of the throttle body 3, side scraper strips 52 are fixedly connected between the two ends of the two scraper blades 51 on the front and rear sides of the throttle body 3. These side scraper strips 52 fit snugly against the sides of the throttle body 3. The side scraper strips 52 expand the cleaning coverage to the side area of ​​the throttle body 3, thereby more thoroughly removing carbon deposits and other sediments. This design provides a more comprehensive cleaning effect and helps maintain the good working condition of the throttle body 3. It is important to note that the thickness of the side scraper strips 52 must be less than the gap between the throttle body 3 and the inner wall of the air chamber 11. Because a certain gap exists between the throttle body 3 and the inner wall of the air chamber 11 to ensure normal rotation of the throttle body 3 and thermal expansion compensation between the throttle body 3 and the throttle body 1, the thickness of the side scraper strips 52 must be less than this gap to allow the side scraper strips 52 to rotate smoothly within this gap.

[0033] The specific structure of the throttle plate 3 fixed on the throttle shaft 2 is as follows: an installation port 21 is provided on the throttle shaft 2, the throttle plate 3 is placed in the installation port 21, and the throttle shaft 2 is provided with pads 22 on both the left and right ends of the installation port 21 for fitting the front and rear sides of the throttle plate 3. In addition, the throttle shaft 2 is provided with screws 6 on both the left and right ends of the installation port 21 for passing through one side of the throttle shaft 2, the pads 22 and the throttle plate 3 and finally threaded onto the other side of the throttle shaft 2. By providing pads 22 on both sides of the installation port 21 on the throttle shaft 2 and fixing the throttle plate 3 with screws 6, the stability of the structure is maintained, and the fixing through such a structure can reduce the impact on the cleaning range of the scraper blade 51.

[0034] In addition, the size of the aforementioned mounting port 21 is sufficient for the scraper 51 and the side scraper 52 to enter. Therefore, when not in use, the scraper 51 and the side scraper 52 can be rotated into the mounting port 21 without affecting the normal operation of the throttle valve.

[0035] In this utility model, the operating shaft 41 extends through the throttle shaft 2, and the operating shaft 41 is rotatably engaged with the throttle shaft 2. The end of the rotating shaft 4 away from the operating shaft 41 is also rotatably engaged with the throttle shaft 2, thus ensuring the stability of the rotating shaft 4 during rotation.

[0036] It should also be noted that the terms used in this utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
