Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a carbon canister control valve with adjustable flow channel angle. Background Technology

[0002] The carbon canister control valve in a car plays a central role in the entire fuel evaporation control process. By controlling the flow of fuel vapor from the carbon canister into the engine, it plays an important role in stabilizing engine operation and reducing fuel evaporation emissions. However, as engine operating conditions become more complex, traditional carbon canister control valves, limited by a fixed flow channel angle, find it difficult to achieve flexible and precise control over the entry angle and flow rate of fuel vapor. Therefore, carbon canister control valves with adjustable flow channel angles have been developed.

[0003] The adjustable flow channel angle carbon canister control valve has the ability to sense the real-time operating conditions of the engine. It can quickly and accurately adjust the flow channel angle of fuel vapor according to the engine's operating status. Through adjustment, fuel vapor can enter the engine more rationally to participate in combustion, which can significantly improve engine power output, effectively reduce fuel consumption, reduce exhaust emissions, and optimize the overall performance of the vehicle.

[0004] However, although adjustable flow channel angle carbon canister control valves are widely used, their internal structure is relatively complex and the flow channel shape is irregular, causing impurities in the oil-gas circuit to accumulate in corners or gaps. These impurities not only hinder the movement of the valve core but also affect the flexibility and accuracy of angle adjustment and wear the seals. The existing solution is to install a filter screen or filter element inside the valve body to filter various foreign particles in the oil-gas circuit. However, the filter screen or filter element needs to be cleaned or replaced regularly. Otherwise, blockage will cause the pressure inside the carbon canister to rise, affecting the normal operation of the carbon canister. Moreover, very fine impurities cannot be completely filtered out. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a carbon canister control valve with an adjustable flow channel angle, which aims to improve the problem that the filter screen or filter element in the prior art needs to be cleaned or replaced regularly and cannot remove very fine impurities.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an adjustable flow channel angle carbon canister control valve, comprising an outer shell, a connecting pipe, and an outer connecting pipe.

A one-way valve is threadedly connected to the bottom of the connecting pipe, and a discharge pipe is threadedly connected to the bottom of the outer side of the one-way valve. A rubber pad is fixedly connected to the rear side of the inner wall of the connecting pipe, and a micro vibrator is fixedly connected to the right side of the rubber pad. A fixed groove is formed at the left end of the outer connecting pipe, and an installation mechanism is provided at the right end of the connecting pipe. The installation mechanism is used to increase the stability of the control valve when installed with external objects.

Permanent magnets are fixedly connected to the right side of the multiple positioning bosses. Multiple positioning slots are opened on the right side of the inner wall of the fixing slot. Magnetic conductive sheets are fixedly connected to the right side of the inner wall of the multiple positioning slots. Multiple sealing gaskets are fixedly connected to the right end of the connecting pipe and the right side of the inner wall of the fixing slot.

[0009] As a further description of the above technical solution:

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the force generated by the flow of the medium in the control valve applies pressure to the turbine blades, causing the turbine shaft to rotate and drive the transmission rod to rotate synchronously under the support of the fixed bracket. This drives the cleaning brush to clean the filter screen. The cleaned impurities fall into the impurity collection tank under the action of gravity. When the pressure sensor senses sufficient pressure, it controls the one-way valve to open, allowing the impurities to be discharged from the control valve under the action of impact force, reducing the contamination of impurities and increasing the service life of the filter screen.

[0023] 2. In this utility model, the connecting pipe and the outer pipe are first horizontally aligned. By inserting the elastic buckles into the corresponding slots, the connecting pipe and the outer pipe can be quickly installed. At the same time, multiple positioning bosses slide into the inner wall of the positioning groove under the guidance of permanent magnets and magnetic sheets, ensuring the accuracy of the connection between the two pipes and avoiding installation errors. Multiple sealing gaskets can prevent pipe leakage and increase the tightness of the pipe connection. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 2 , Figure 4 and Figure 5This utility model provides an embodiment of a carbon canister control valve with adjustable flow channel angle, including an outer shell 1, a connecting pipe 2, and an outer connecting pipe 3. A fixed bracket 6 is fixedly connected to the inner wall of the connecting pipe 2, supporting a transmission rod 7 to prevent the turbine shaft 8 from falling off. The transmission rod 7 is slidably connected to the inner wall of the fixed bracket 6, connecting the turbine shaft 8 and a cleaning brush 10. The turbine shaft 8 is fixedly connected to the right end of the transmission rod 7, transmitting the force generated by the rotation of the turbine blades 9. Multiple turbine blades 9 are fixedly connected to the outer side of the turbine shaft 8. Power is generated by the rotation of multiple turbine blades 9. A cleaning brush 10 is fixedly connected to the left end of the transmission rod 7. The cleaning brush 10 can clean the shape memory alloy filter 15. A shape memory alloy filter 15 is fixedly connected to the middle of the inner wall of the connecting pipe 2. The shape memory alloy filter 15 can intercept impurities. An impurity collection groove 11 is opened at the bottom of the inner wall of the connecting pipe 2. Impurities are collected through the impurity collection groove 11. A pressure sensor 14 is fixedly connected to the rear side of the inner wall of the impurity collection groove 11. The pressure sensor 14 is used to detect the pressure in the impurity collection groove 11. Impurities can be cleaned in a timely manner. A one-way valve 13 is threadedly connected to the bottom of connecting pipe 2. The one-way valve 13 prevents backflow of already discharged impurities. A discharge pipe 12 is threadedly connected to the bottom outer side of the one-way valve 13, providing space for impurity removal. A rubber pad 16 is fixedly connected to the rear inner wall of connecting pipe 2. The rubber pad 16 reduces the impact of the micro-vibrator 17 on connecting pipe 2. A micro-vibrator 17 is fixedly connected to the right side of the rubber pad 16, making it easier for impurities to fall off the filter screen. The left side of the outer pipe 3... The end is provided with a fixing groove 5, which provides space for the connection of the connecting pipe 2 and the external pipe 3. The right end of the connecting pipe 2 is provided with an installation mechanism 4, which is used to increase the installation stability of the control valve and external objects. The distance between multiple turbine blades 9 is the same, and the outer sides of multiple turbine blades 9 are all rounded. The top of the inner wall of the discharge pipe 12 is fixedly connected with a threaded ring 24. The top and bottom of the outer side of the one-way valve 13 are provided with threaded grooves 25. The threaded ring 24 and the threaded groove 25 are used together to make the discharge pipe 12 and the one-way valve 13 easy to replace.

[0035] Specifically, after the device is installed, fuel vapor containing impurities flows into the connecting pipe 2 from the external pipe 3. When the vapor passes through the shape memory alloy filter screen 15, the filter screen blocks the impurities on one side, and the purified fuel vapor continues to flow to the subsequent flow channel, ensuring that the fuel vapor entering the engine meets the requirements and reducing the damage of impurities to the engine. Over time, the intercepted impurities gradually accumulate on the surface of the filter screen, while the flow of fuel vapor drives the turbine blades 9 to rotate. The power generated by the turbine blades 9 is transmitted to the transmission rod 7 via the turbine shaft 8, which drives the cleaning brush 10 to rotate, mechanically cleaning the shape memory alloy filter screen 15, removing the impurities remaining on the filter screen, and causing the impurities to fall into the impurity collection tank 11 under the action of gravity. At the same time, the micro vibrator 17 is activated and begins high-frequency vibration. The vibration is transmitted to the shape memory alloy filter screen 15 through the buffer of the rubber pad 16, so that the adhering impurities are removed. Impurities on the filter screen are easier to detach. The pressure sensor 14 in the impurity collection tank 11 continuously monitors the pressure inside the tank. When impurities accumulate to a certain extent, the pressure sensor 14 sends a signal. Upon receiving the signal from the pressure sensor 14, the one-way valve 13 opens, and the impurities in the impurity collection tank 11 enter the discharge pipe 12 and are finally discharged from the carbon canister control valve. The presence of the one-way valve 13 ensures that impurities can only flow in one direction, preventing discharged impurities from flowing back into the impurity collection tank 11 and ensuring the efficiency of impurity cleaning. If the one-way valve 13 or the discharge pipe 12 is blocked or damaged, since the threaded ring 24 on the top of the inner wall of the discharge pipe 12 and the threaded grooves 25 on the top and bottom of the outer side of the one-way valve 13 are connected by threads, maintenance personnel can easily unscrew the discharge pipe 12 and the one-way valve 13 by rotating them to replace the new parts. The operation is convenient and reduces maintenance costs and time.

[0036] Reference Figure 3 , Figure 4 and Figure 7 The installation mechanism 4 includes two elastic buckles 401, the left sides of which are fixedly connected to the middle of the right end of the connecting pipe 2. Two slots 402 are formed on the left side of the inner wall of the outer pipe 3, allowing the two elastic buckles 401 to engage with the two slots 402 respectively, facilitating installation and disassembly. Multiple positioning bosses 403 are fixedly connected to the right end of the connecting pipe 2, and permanent magnets 404 are fixedly connected to the right side of each positioning boss 403. Multiple positioning slots 405 are formed on the right side of the inner wall of the fixing groove 5, and multiple positioning bosses... 403 is slidably connected to the inner wall of multiple positioning grooves 405, playing a positioning and guiding role during installation. Magnetic conductive sheets 406 are fixedly connected to the right side of the inner wall of each of the multiple positioning grooves 405. The permanent magnet 404 can be magnetically attracted to the magnetic conductive sheets 406, which can automatically correct the position to a certain extent and improve the accuracy of installation. Multiple sealing gaskets 407 are fixedly connected to the right end of the connecting pipe 2 and the right side of the inner wall of the fixing groove 5. The multiple sealing gaskets 407 can increase the tightness of the connection between the connecting pipe 2 and the outer pipe 3 and prevent leakage.

[0037] Specifically, align the end of the connecting pipe 2 with the installation mechanism 4 with the fixing groove 5 on the left end of the outer pipe 3. At this time, the multiple positioning protrusions 403 are initially aligned with the multiple positioning grooves 405 on the right side of the inner wall of the fixing groove 5. Slide the positioning protrusions 403 along the inner wall of the positioning groove 405 so that the positioning groove 405 plays a positioning and guiding role, guiding the connecting pipe 2 to be accurately inserted into the fixing groove 5, reducing deviations during installation and improving installation efficiency. Continue to push the connecting pipe 2 into the fixing groove 5. When it is pushed to a certain position, the two elastic buckles 401 in the middle of the right end of the connecting pipe 2 correspond to the two slots 402 opened on the left side of the inner wall of the outer pipe 3. Since the elastic buckles 401 are elastic, they will be deformed by the pressure of the inner wall of the outer pipe 3 during the pushing process. When the elastic buckles 401 reach the position of the slots 402, the elasticity of the elastic buckles 401 is restored, and they are locked into the slots 402, realizing the initial fixing of the connecting pipe 2 and the outer pipe 3. The positioning boss 403 facilitates installation and operation, and at the same time, prevents the connecting pipe 2 from accidentally coming out to a certain extent. As the positioning boss 403 slides along the positioning groove 405, the permanent magnet 404 fixedly connected to the right side of the positioning boss 403 gradually approaches the magnetic guide plate 406 fixedly connected to the right side of the inner wall of the positioning groove 405. Due to the magnetic attraction between the permanent magnet 404 and the magnetic guide plate 406, the permanent magnet 404 automatically approaches and attracts the magnetic guide plate 406 under the action of magnetic force, automatically correcting the relative position of the connecting pipe 2 and the outer pipe 3, increasing the stability of the connection between the connecting pipe 2 and the outer pipe 3. As the connecting pipe 2 is gradually inserted into the fixing groove 5, the sealing gasket 407 is squeezed. Due to the good elasticity and sealing performance of the sealing gasket 407, it fills the small gap between the connecting pipe 2 and the outer pipe 3 under the squeezing action, increasing the tightness of the connection, effectively preventing the leakage of fuel vapor and other media from the connection, and ensuring the sealing performance of the carbon canister control valve during operation.

[0038] Reference Figure 1 , Figure 4 and Figure 6 A fixing plate 21 is fixedly connected to the left side of the connecting pipe 2, and a warning sign 22 is fixedly connected to the right side of the fixing plate 21. The warning sign 22 can remind the user of the precautions for using the carbon canister control valve. A pressure sensor 2 18 is fixedly connected to the left side of the inner wall of the connecting pipe 2. The pressure sensor 2 18 can detect the pressure generated by the medium passing through the filter screen. A display screen 19 is fixedly connected to the front side of the outer wall of the connecting pipe 2. The display screen 19 displays the data detected by the pressure sensor 2 18. A sealing ring 23 is fixedly connected to the inner wall of the fixing groove 5. The sealing ring 23 matches the size of the outer wall of the connecting pipe 2. The sealing ring 23 can re-seal the connection between the right end of the outer wall of the connecting pipe 2 and the left end of the inner wall of the outer pipe 3, reducing the possibility of leakage of substances inside the control valve. A rubber ring 20 is fixedly connected to the outer side of the shape memory alloy filter screen 15. The rubber ring 20 adopts a ring design. The rubber ring 20 can prevent water leakage around the filter screen and also increase the stability of the filter screen.

[0039] Specifically, the fixing plate 21 is fixedly connected to the left side of the connecting pipe 2, and then the warning sign 22 is fixed to the right side of the fixing plate 21. The warning sign 22 is marked with the usage precautions of the carbon canister control valve. After installation, it can intuitively remind the user of the relevant operating points. The pressure sensor 18 is installed on the left side of the inner wall of the connecting pipe 2, and then the display screen 19 is fixed on the front side of the outer wall of the connecting pipe 2. The electrical connection between the pressure sensor 18 and the display screen 19 is completed. When fuel vapor containing impurities flows into the connecting pipe 2 from the outer pipe 3 and is filtered by the shape memory alloy filter screen 15, the pressure sensor 18 continuously detects the pressure generated by the medium passing through the filter screen and transmits the detection data to the display screen 19 for real-time display. The user can understand the working status of the filter screen and the medium passage by observing the data on the display screen 19. The rubber ring 20 is fitted on the outside of the shape memory alloy filter screen 15. Since the rubber ring 20 adopts a ring design, it can fit tightly with the filter screen, which not only avoids water leakage around the filter screen, but also increases the stability of the filter screen.

[0040] Working principle: When fuel vapor containing impurities flows from the external pipe 3 into the connecting pipe 2 and passes through the filter screen, the shape memory alloy filter screen 15 utilizes its physical barrier properties to block the impurities on one side. The purified fuel vapor can then flow into the engine through subsequent channels, preventing impurities from causing wear and blockage to the precision components inside the engine, thus ensuring normal engine operation. The kinetic energy generated by the flow of fuel vapor drives the turbine blades 9 to rotate. The turbine blades 9 transmit the power sequentially through the turbine shaft 8 to the transmission rod 7, which in turn drives the cleaning brush 10 to rotate and mechanically clean the shape memory alloy filter screen 15, scraping off the impurities accumulated on the filter screen surface. The impurities then fall into the filter screen under gravity. The collection tank 11 performs preliminary cleaning of the filter screen and maintains its filtration efficiency. After the micro vibrator 17 is activated, it generates high-frequency vibration. The vibration is buffered by the rubber pad 16 and then transmitted to the shape memory alloy filter screen 15. The rubber pad 16 can reduce the adverse effects of vibration on the connecting pipe 2 and ensure that the vibration is effectively applied to the filter screen, making it easier for impurities attached to the filter screen to fall off and reducing the residue of impurities on the filter screen. The pressure sensor 14 in the impurity collection tank 11 monitors the pressure in the tank in real time. As impurities accumulate, the pressure gradually increases. When the pressure reaches the preset threshold, the one-way valve 13 opens, and the impurities in the impurity collection tank 11 enter the discharge pipe 12 and are finally discharged from the carbon canister control valve.

[0041] Furthermore, the positioning boss 403 slides along the inner wall of the positioning groove 405, which provides a clear path for the movement of the positioning boss 403, playing a positioning and guiding role. This allows the connecting pipe 2 to move accurately along the predetermined direction during insertion into the fixing groove 5, improving installation efficiency and accuracy. During the process of the connecting pipe 2 being pushed into the fixing groove 5, the elastic buckle 401 is deformed by the pressure of the inner wall of the outer pipe 3. When it reaches the position of the slot 402, it elastically recovers and snaps into the slot 402, achieving the initial fixation of the connecting pipe 2 and the outer pipe 3. The operation is simple and quick, and it can prevent the connecting pipe 2 from accidentally coming out. Due to the permanent magnet 404 and the magnetic conductivity... There is a magnetic attraction between the plates 406. When the two are close enough, the permanent magnet 404 automatically guides the magnetic plate 406 to approach and attract it under the action of magnetic force. This can automatically correct the relative position of the connecting pipe 2 and the outer pipe 3, making the connection more precisely aligned and further increasing the stability of the connection. As the connecting pipe 2 is gradually inserted into the fixing groove 5, the sealing gasket 407 on the right end of the connecting pipe 2 and the right side of the inner wall of the fixing groove 5 is squeezed. The good elasticity of the sealing gasket 407 allows it to deform when squeezed, filling the tiny gap between the connecting pipe 2 and the outer pipe 3. At the same time, it can prevent fuel vapor from leaking from the gap and ensure the sealing of the carbon canister control valve during operation.

[0042] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
