[0066] Reference below Figures 1-15 A CVS valve assembly 20 according to an embodiment of the present invention is described.

[0067] According to the CVS valve assembly 20 of the embodiment of the first aspect of the present invention, the CVS valve assembly 20 is used for the carbon canister 100, and the carbon canister 100 is generally installed between the fuel tank and the engine. Since fuel is a liquid that is easy to volatilize, the fuel tank is often filled with steam at room temperature, and the function of the carbon canister 100 is to introduce steam into the carbon canister 100 to prevent the steam in the fuel tank from volatilizing into the air. The CVS valve assembly 20 is used to fill the carbon canister 100 with air and guide the steam in the carbon canister 100 to flow to the engine for combustion.

[0068] The carbon canister 100 includes a box body 11 and a sleeve 12 . The sleeve 12 is connected to the box body 11 . The box body 11 has an opening communicating with the sleeve 12 . The sleeve 12 is used to install the CVS valve assembly 20 .

[0069] The CVS valve assembly 20 includes a valve body 1 and a first vent pipe 4. The valve body 1 is used to control the opening or closing of the carbon canister 100. The first vent pipe 4 is connected to the valve body 1, and the first vent pipe 4 is connected to the tank 11. The fuel vapor in the tank 11 enters the engine through the first vent pipe 4 and the valve body 1.

[0070] The CVS valve assembly 20 includes a locking mechanism 6, which includes a locking block 61, a first elastic member 62, a first snap ring 63, and a second snap ring 64. The locking block 61 is movably connected to the inner wall of the sleeve 12 via the first elastic member 62. The locking block 61 can be retracted relative to the inner wall of the sleeve 12 by the elastic action of the first elastic member 62. For example, the first elastic member 62 can be a spring. The locking block 61 has a first guide bevel 611. The first snap ring 63 is fixedly mounted on the outer circumference of the first vent pipe 4. The second snap ring 64 is movably mounted on the outer circumference of the first vent pipe 4. The second snap ring 64 can move on the outer circumference of the first vent pipe 4. The second snap ring 64 has a second guide bevel 641.

[0071] The first snap ring 63 and the second snap ring 64 have a first state in which they are separated from each other and a second state in which they are close to each other. In the direction from the sleeve 12 to the first vent pipe 4, the first guide slope 611 extends obliquely toward the housing 11, and in the direction from the first vent pipe 4 to the sleeve 12, the second guide slope 641 extends obliquely toward the housing 11. The first guide slope 611 is used to guide the movement of the first snap ring 63 so that the first snap ring 63 can smoothly move to the locking position of the locking block 61 and be locked by the locking block 61. In the first state, the first snap ring 63 and the second snap ring 64 are separated from each other, and the locking block 61 is located between the first snap ring 63 and the second snap ring 64. The locking block 61 is used to lock the first snap ring 63. The second guide bevel 641 is used to guide the second snap ring 64 and the first snap ring 63 to move relative to the locking block 61, so that the second snap ring 64 and the first snap ring 63 can move out of the locking position of the locking block 61. The second guide bevel 641 can push the locking block 61 to shrink under the action of the first elastic member 62, so that the locking block 61 is in an unlocked state, so that the second snap ring 64 and the first snap ring 63 can move out of the locking position, so that the locking mechanism 6 is unlocked, and the first vent pipe 4 and the valve body 1 can be removed from the box body 11.

[0072] Install the CVS valve assembly 20 on the carbon canister 100, and place the first ventilation pipe 4 and the first clamping ring 63 and the second clamping ring 64 located on the first ventilation pipe 4 into the sleeve 12. The first clamping ring 63 contacts the first guide slope 611 to drive the locking block 61 to contract, so that the first clamping ring 63 moves to one side of the locking block 61. At this time, the locking block 61 extends under the elastic action of the first elastic member 62 and is located between the first clamping ring 63 and the second clamping ring 64 to lock the first clamping ring 63, thereby locking the first intake pipe and the valve body 1 to prevent the first ventilation pipe 4 and the valve body 1 from falling off.

[0073] When the CVS valve assembly 20 needs to be inspected or replaced, the first ventilation pipe 4 can be pushed, and the second clamping ring 64 contacts the first guide slope 611 to drive the locking block 61 to contract, so that the second clamping ring 64 moves to the second state. Under the guidance of the second guide slope 641, the second guide slope 641 can push the locking block 61 to contract, and the first ventilation pipe 4 can drive the second clamping ring 64 and the first clamping ring 63 to move out of the locking position of the locking block 61, so that the locking mechanism 6 is unlocked, and the first ventilation pipe 4 and the valve body 1 can be removed from the box body 11, which can facilitate the inspection or replacement of the CVS valve assembly 20.

[0074] For example, there may be multiple locking blocks 61, which are arranged at intervals along the circumference of the inner wall of the sleeve 12, and each locking block 61 is connected to a first elastic member 62, which can make the locking block 61 lock the first clamping ring 63 more firmly.

[0075] When the CVS valve assembly 20 needs to be replaced, only the CVS valve assembly 20 needs to be replaced. Compared with replacing the entire carbon canister 100, the cost is lower and it is more convenient to perform regular maintenance on the CVS valve assembly 20. Rust on the CVS valve assembly 20 can be discovered and handled in time, thereby extending the service life of the CVS valve assembly 20.

[0076] According to the CVS valve assembly 20 of the embodiment of the present invention, the CVS valve assembly 20 is detachably locked to the box body 11 of the carbon canister 100 through a locking structure, which can facilitate the replacement of the CVS valve assembly 20 and reduce the replacement cost; at the same time, it is convenient to perform regular maintenance on the CVS valve assembly 20, and can timely detect and deal with rust on the CVS valve assembly 20, thereby extending the service life of the CVS valve assembly 20.

[0077] According to some embodiments of the present invention, referring to Figures 1-10 A first magnetic member 651 is provided on the side of the first snap ring 63 facing the second snap ring 64, and a second magnetic member 652 is provided on the side of the second snap ring 64 facing the first snap ring 63. The first magnetic member 651 and the second magnetic member 652 magnetically repel each other, so that the first snap ring 63 and the second snap ring 64 are spaced apart along the axial direction of the first ventilation pipe 4. When the CVS valve assembly 20 is installed, there is a repulsive force between the first snap ring 63 and the second snap ring 64, so that the locking block 61 can be located between the first snap ring 63 and the second snap ring 64, which is used to lock the first snap ring 63 in the locking position.

[0078] The elastic force of the first elastic member 62 is greater than the repulsive force between the first magnetic member 651 and the second magnetic member 652. When disassembling the CVS valve assembly 20, the elastic force of the first elastic member 62 pushing the locking block 61 can overcome the repulsive force between the first magnetic member 651 and the second magnetic member 652, so that the first snap ring 63 and the second snap ring 64 can be located on the same side of the locking block 61.

[0079] According to some embodiments of the present invention, referring to Figures 1-10 The first snap ring 63 has a first annular groove 631 with an opening toward the second snap ring 64, and the second snap ring 64 has a second annular groove 642 with an opening toward the first snap ring 63. A first magnetic part 651 is provided in the first annular groove 631, and a second magnetic part 652 is provided in the second annular groove 642, which can facilitate the installation of the first magnetic part 651 and the second magnetic part 652.

[0080] According to some embodiments of the present invention, referring to Figures 1-10 The first snap ring 63 has a third guide slope 632, and the extension direction of the third guide slope 632 is the same as the extension direction of the first guide slope 611. When installing the CVS valve assembly 20, the cooperation of the first guide slope 611 and the third guide slope 632 can reduce the friction between the first snap ring 63 and the locking block 61, and can save the force of the first snap ring 63 when pushing the locking block 61 to move, so that the first snap ring 63 can move quickly to the locked position.

[0081] According to some embodiments of the present invention, referring to Figures 1-10 The second snap ring 64 has a fourth guide slope 643, and the extension direction of the fourth guide slope 643 is the same as the extension direction of the first guide slope 611. When the second snap ring 64 pushes the locking block 61, the fourth guide slope 643 can cooperate with the first guide slope 611, which can reduce the friction between the second snap ring 64 and the locking block 61, and save the force of the second snap ring 64 when pushing the locking block 61 to move, so that the second snap ring 64 can push the locking block 61 to move smoothly and quickly.

[0082] According to some embodiments of the present invention, referring to Figures 1-10 One end of the first snap ring 63 is fixedly connected to the first vent tube 4, and the other end extends toward the sleeve 12, defining an annular cavity 633 between the first snap ring 63 and the first vent tube 4. The outer peripheral wall of the annular cavity 633 forms a third guide slope 632. In the second state, the fourth guide slope 643 is adapted to be located within the annular cavity 633. When the CVS valve assembly 20 is disassembled, the fourth guide slope 643 can cooperate with the annular cavity 633, allowing the first snap ring 63 to smoothly move out of the locked position of the locking block 61.

[0083] According to some embodiments of the present invention, referring to Figures 1-10 The locking block 61 is provided with a chamfered corner 612 at the corner near the first ventilation pipe 4. When the CVS valve assembly 20 is disassembled, the second guide inclined surface 641 can reduce the friction force of pushing the locking block 61 when pushing the locking block 61 to move, so that the second guide inclined surface 641 can push the locking block 61 quickly and effortlessly, so that the second snap ring 64 and the first snap ring 63 can be quickly unlocked.

[0084] According to some embodiments of the present invention, referring to Figures 1-10 The locking mechanism 6 also includes a third snap ring 66, which is fixedly sleeved on the outer peripheral side of the first vent pipe 4 and is located on the side of the second snap ring 64 away from the first snap ring 63. A sliding groove 13 is provided on the inner wall of the sleeve 12, and the sliding groove 13 includes a first vertical groove 131. The first vertical groove 131 extends along the axial direction of the sleeve 12, and the third snap ring 66 has a protrusion 661. The protrusion 661 slides in the sliding groove 13. In the first state, the protrusion 661 is located on the bottom wall of the first vertical groove 131, so that the first snap ring 63 is in the locked position, preventing the first vent pipe 4 from continuing to move under the action of external force, thereby driving the second snap ring 64 to move, so that the locking structure is unlocked.

[0085] According to some embodiments of the present invention, referring to Figures 1-10 The slide groove 13 also includes a first transverse groove 132 and a second vertical groove 133. The first transverse groove 132 extends along the circumferential direction of the sleeve 12. The first transverse groove 132 is connected between the first vertical groove 131 and the second vertical groove 133. The first vertical groove 131 and the second vertical groove 133 are spaced apart along the circumferential direction of the sleeve 12. In the second state, the protrusion 661 is located in the second vertical groove 133. The protrusion 661 can move along the second vertical groove 133 so that the first ventilation pipe 4 can continue to move, and the second snap ring 64 is moved to push the locking block 61 to retract, so that the first snap ring 63 and the second snap ring 64 are in the second state. In the second state, under the action of external force, the locking structure can be unlocked.

[0086] For example, two sliding grooves 13 are provided on the inner wall of the sleeve 12 , and the two sliding grooves 13 are spaced apart along the circumference of the inner wall of the sleeve 12 . The length of the first transverse groove 132 is 1 / 6 of the circumference of the inner wall of the sleeve 12 .

[0087] According to some embodiments of the present invention, referring to Figures 1-10 The first ventilation pipe 4 has a first pipe section 41 and a second pipe section 42. The diameter of the first pipe section 41 is larger than the diameter of the second pipe section 42. The first pipe section 41 abuts against the inner wall of the sleeve. When the first ventilation pipe 4 moves in the sleeve, the first pipe section 41 can move along the inner wall of the sleeve, which can increase the stability of the first ventilation pipe 4 when it moves.

[0088] The first snap ring, the second snap ring 64 and the third snap ring 66 are all sleeved on the second pipe section 42 . The first snap ring 63 , the second snap ring 64 and the third snap ring 66 are suitable for abutting against the inner wall of the sleeve 12 .

[0089] According to some embodiments of the present invention, referring to Figures 1-10 A mounting groove 121 is provided on the inner wall of the sleeve 12, the first elastic member 62 is located in the mounting groove 121, and the locking block 61 is telescopically located in the mounting groove 121, which can provide installation space for the installation of the first elastic member 62 and the locking block 61, and also provide retraction space for the first elastic member 62 and the locking block 61.

[0090] According to some embodiments of the present invention, referring to Figures 1-10 The locking mechanism 6 also includes a second elastic member 67. The sleeve 12 has an annular bottom wall 122 extending toward the center of the sleeve 12. The annular bottom wall 122 defines a through hole 1221, which is communicated with the first ventilation pipe 4. That is, the through hole 1221 is used to connect the box body 11 and the first ventilation pipe 4. A bracket 68 is provided on the side of the first ventilation pipe 4 facing the annular bottom wall 122. The second elastic member 67 is located between the annular bottom wall 122 and the bracket 68, which can support the first ventilation pipe 4, thereby preventing the first ventilation pipe 4 from driving the second clamping ring 64 to push the locking block 61 to move under non-human action, and improving the friction between the first clamping ring 63 and the locking block 61, thereby increasing the firmness of the first clamping ring 63 when locked.

[0091] According to some embodiments of the present invention, referring to Figures 1-14 The CVS valve assembly 20 also includes a shell 2 and a second ventilation pipe 5. The shell 2 is located between the first ventilation pipe 4 and the second ventilation pipe 5. The first ventilation pipe 4 and the second ventilation pipe 5 are both connected to the shell 2. A filter plate 3 is provided in the shell 2. The valve body 1 is connected to the shell 2 and is located on the side of the filter plate 3 away from the second ventilation pipe 5.

[0092] The second ventilation pipe 5 is used to bring air from the external environment into the box body 11. The filter plate 3 can filter the air to filter out dust in the air, so that the air entering the carbon canister 100 is cleaner. The valve body 1 is located on the side of the filter plate 3 away from the second ventilation pipe 5, so that the air entering the valve body 1 through the second ventilation pipe 5 is filtered by the filter plate 3.

[0093] According to some embodiments of the present invention, referring to Figure 11-14The filter plate 3 includes a plurality of sequentially connected sub-filter plates 31. The angle between two adjacent sub-filter plates 31 is acute, which increases the contact area between the filter plate 3 and the air, allowing the filter plate 3 to filter more air and allowing more air to enter the carbon canister 100. For example, there may be four, five, or six sub-filter plates 31, and the angle between two adjacent sub-filter plates 31 may be 45°, 50°, or 60°.

[0094] According to some embodiments of the present invention, referring to Figure 11-14 The CVS valve assembly 20 also includes a dust removal assembly 7. An accommodating chamber 32 with an opening toward the second vent pipe 5 is defined between two adjacent sub-filter plates 31. The dust removal assembly 7 is located within the accommodating chamber 32 and is used to remove dust from the filter plates 3. The dust removal assembly 7 includes a mounting plate 71, a support frame 72, and a knocking rod 74. The knocking rod 74 is connected to the mounting plate 71 and extends toward the sub-filter plates 31 and is adapted to abut against the sub-filter plates 31. Curved grooves 711 are provided on both sides of the mounting plate 71 near the sub-filter plates 31. The support frame 72 is supported between the sub-filter plates 31 and the mounting plate 71. The support frame 72 has a slide bar 73 that slidably engages with the curved groove 711. The support frame 72 has a push-pull rod 78 located at the bottom of the mounting plate 71. The push-pull rod 78 passes through the side wall of the housing 2 and is adapted to slide within the housing 2 so that the slide bar 73 slides within the curved groove 711.

[0095] When the push-pull rod 78 is pulled and pulled outside the shell 2, the support frame 72 can drive the sliding rod 73 to slide in the curved sliding groove 711. When the sliding rod 73 slides in the curved sliding groove 711, it can drive the mounting plate 71 to slide in the shell 2, thereby driving the knocking rod 74 on the mounting plate 71 to move, so that the knocking rod 74 can knock on the sub-filter plate 31 to shake off the dust on the sub-filter plate 31, which can improve the effect of the filter plate 3 in filtering the air.

[0096] According to some embodiments of the present invention, referring to Figure 11-14 A dust pusher 76 is connected to the side of the support frame 72 near the sub-filter plates 31. When the push-pull rod 78 is pulled, the support frame 72 can drive the dust pusher 76 to move, thereby piling dust on the filter plates 3 to one side. The dust pusher 76 is a triangular block that matches the angle between two adjacent sub-filter plates 31. This allows the dust pusher 76 to push more dust off the filter plates 3, achieving a better pushing effect.

[0097] According to some embodiments of the present invention, referring to Figure 11-14 The side wall of the shell 2 has multiple dust removal ports 21, which are arranged opposite to the dust pushing block 76. The dust pushed by the dust pushing block 76 can be removed through the dust removal port 21, thereby ensuring the filtering effect of the filter plate 3.

[0098] The dust removal port 21 is installed with a dust plug 22. When the dust removal component 7 is not needed for dust removal, the dust plug 22 can be installed to the dust removal port 21 to prevent dust in the external air from entering the shell 2. When the dust removal component 7 is needed for dust removal, the dust plug 22 can be removed and the dust can be removed from the dust removal port 21.

[0099] According to some embodiments of the present invention, referring to Figure 11-14 The dust pushing block 76 is a sponge member, which is made of a sponge material. The sponge material has gaps and can absorb more dust on the filter plate 3.

[0100] According to some embodiments of the present invention, referring to Figure 11-14 A hitting ball 75 is connected to the side of the knocking rod 74 close to the sub-filter plate 31. The hitting ball 75 can be used to hit the filter plate 3, which can increase the contact area between the hitting ball 75 and the filter plate 3, further increase the force of the hitting ball 75 hitting the filter plate 3, and can knock down more dust.

[0101] According to some embodiments of the present invention, referring to Figure 11-14 The knocking rod 74 and the striking ball 75 are both rubber parts, and the rubber parts have good elasticity and wear resistance.

[0102] According to some embodiments of the present invention, referring to Figure 11-14 A third elastic member 77 is connected between the mounting plate 71 and the top wall of the shell 2. The mounting plate 71 can move within the shell 2, and the third elastic member 77 can provide buffering and vibration reduction effects.

[0103] When the dust on the filter plate 3 needs to be cleaned, the dust plug 22 is removed from the dust removal port 21, and then the push-pull rod 78 is moved back and forth, so that the push-pull rod 78 drives the support frame 72 to move. When the support frame 72 moves, the two slide bars 73 are also driven to move. Since the slide bar 73 is slidably connected to the curved slide groove 711, when the slide bar 73 moves, the mounting plate 71 will move up and down under the influence of the curved slide groove 711.

[0104] When the mounting plate 71 moves downward, it drives the multiple knocking rods 74 and the striking balls 75 to move downward, thereby causing the multiple striking balls 75 to knock the filter plate 3, thereby vibrating the filter plate 3, and causing the dust on the filter plate 3 to slide into the accommodating cavity 32 of the filter plate 3.

[0105] When the support frame 72 moves, the dust pushing block 76 will be driven to move, and the dust pushing block 76 will push the dust on the filter plate 3 to move, and then push the dust in the accommodating cavity 32 of the filter plate 3 to the dust removal port 21, so that the dust is discharged through the dust removal port 21.

[0106] According to some embodiments of the present invention, referring to Figure 1-Figure 2 、 Figure 15 The CVS valve assembly 20 also includes a support mechanism 8, which is located between the shell 2 and the box body 11. The support mechanism 8 includes a bottom plate 81, a rotating ring 82, a telescopic rod 83, a fixed plate 84 and a fourth elastic member 85. The bottom plate 81 is fixedly connected to the box body 11, the fixed plate 84 is fixedly connected to the shell 2, and the rotating ring 82 is rotatably connected to the bottom plate 81. The bottom plate 81, the rotating ring 82 and the fixed plate 84 are all annular and are all located on the outer periphery of the sleeve 12. The telescopic rod 83 and the fourth elastic member 85 are supported between the rotating ring 82 and the fixed plate 84 and are located on the outer periphery of the sleeve 12.

[0107] When the second vent pipe 5 of the CVS valve assembly 20 needs to be installed and moved in the sleeve 12, the shell 2 can be pushed to move, and the shell 2 can drive the second vent pipe 5 to move, and the telescopic rod 83 and the fourth elastic member 85 can be contracted, so that the shell 2 can rotate and move.

[0108] According to some embodiments of the present invention, referring to Figure 1-Figure 2 、 Figure 15 The telescopic rod 83 and the fourth elastic member 85 are both provided with multiple and equal numbers. The fourth elastic member 85 is a spring, which is correspondingly arranged on the outer peripheral side of the telescopic rod 83, which can further increase the supporting strength between the shell 2 and the box body 11, and can also prevent the shell 2 from moving under non-human influence.

[0109] According to some specific embodiments of the present invention, referring to Figures 1-15 When the CVS valve assembly 20 needs to be installed on the sleeve 12 , the first vent pipe 4 is aligned with the sleeve 12 so that the two protrusions 661 on the third clamping ring 66 are aligned with the two first vertical grooves 131 .

[0110] Then, the shell 2 is moved downward, so that the first ventilation pipe 4, the first snap ring 63, the second snap ring 64 and the third snap ring 66 move downward, and then the two protrusions 661 move downward along the two first vertical grooves 131. As the first ventilation pipe 4 moves downward, the first snap ring 63 will contact the multiple locking blocks 61, and then push the multiple locking blocks 61 to move to a position away from the center of the sleeve 12.

[0111] When the first ventilation pipe 4 continues to move downward, the first clamping ring 63 will move to the bottom of the multiple locking blocks 61. At this time, the first elastic members 62 in the multiple mounting cavities will push the multiple locking blocks 61 to move, thereby making the bottoms of the multiple locking blocks 61 contact with the tops of the first clamping ring 63. At this time, the two protrusions 661 are located on the bottom wall of the first vertical groove 131, so that the first ventilation pipe 4 cannot continue to move toward the direction of the box body 11, and the first clamping ring 63 cannot be removed from the sleeve 12, so that the first ventilation pipe 4 cannot be removed from the sleeve 12, thereby quickly installing the CVS valve assembly 20 on the sleeve 12.

[0112] When the CVS valve assembly 20 needs to be removed from the sleeve 12 , the housing 2 is rotated to drive the first vent pipe 4 , the third clamping ring 66 and the two protrusions 661 to rotate, thereby positioning the two protrusions 661 in the second vertical grooves 133 .

[0113] Then, by pressing the housing 2 downward, the first vent pipe 4 and the third snap ring 66 move downward, thereby pushing the second snap ring 64 downward, and then the second snap ring 64 passes through the multiple locking blocks 61, so that the second snap ring 64 and the first snap ring 63 are both located below the multiple locking blocks 61. At this time, by quickly and continuously moving the first vent pipe 4 upward, the first snap ring 63 is driven to move upward, and the fourth guide slope 643 of the second snap ring 64 is inserted into the annular cavity 633. As the first ventilation tube 4 continues to move upward, the second guide slope 641 of the second clamping ring 64 will push the multiple locking blocks 61 to move away from the center of the sleeve 12. As the first ventilation tube 4 continues to move upward, the second clamping ring 64 and the first clamping ring 63 will both move to above the multiple locking blocks 61. At this time, the repulsive force of the first magnetic part 651 and the second magnetic part 652 will push the second clamping ring 64 to move upward, thereby causing a gap between the first clamping ring 63 and the second clamping ring 64.

[0114] Then, by rotating the shell 2 counterclockwise, the first ventilation pipe 4, the third clamping ring 66 and the two protrusions 661 rotate, and then the two protrusions 661 move into the two first vertical grooves 131. Finally, by moving the shell 2 upward, the first ventilation pipe 4 can be quickly removed from the sleeve 12.
