Detailed Implementation

[0015] 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.

[0016] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a carbon canister solenoid valve with a protective structure, comprising: The carbon canister solenoid valve body 100 has an air inlet 200 at one end and an air outlet 300 and a wiring terminal 400 at the other end. The carbon canister solenoid valve body 100 is equipped with an electromagnet, valve body, piston, armature, electromagnetic coil, return spring and housing. The working principle of the carbon canister solenoid valve is as follows: When the car engine is running, the vapor produced by the fuel system is drawn into the carbon canister. When the engine is working normally, the electromagnet is excited by the power supply current, generating a strong magnetic field that pushes the piston upward, opening the inlet passage of the valve body. The fuel vapor enters the valve body through the inlet and flows to the car's carbon canister for storage. When the engine stops working or the load is low, the power supply current is cut off, the magnetic field of the electromagnet disappears, the piston returns to its original position, and the inlet of the valve body is closed, preventing fuel vapor from entering the combustion chamber, thereby reducing exhaust emissions.

[0017] The I-beam plate 500 is fixed to the outer surface of the carbon canister solenoid valve body 100 by a mounting column; The positioning component 600 is used to fix the air inlet pipe and the air outlet pipe that are inserted into the air inlet end 200 and the air outlet end 300, respectively. The positioning component 600 includes two sets of clamping plates 601 that are symmetrically slidably disposed on the lower surface of the two I-shaped plates 500 and correspond to the air inlet end 200 and the air outlet end 300, respectively. Each set of two clamping plates 601 is a set. In each set, a semi-circular positioning plate 602 is fixed on the opposite surface of the two clamping plates 601. The positioning component 600 also includes a rotating disk 603 that is rotatably disposed on the upper surface of the I-shaped plate 500 for driving the two clamping plates 601 in each set to move simultaneously toward the middle. The upper surface of the rotating disk 603 is provided with a hexagonal groove.

[0018] See Figure 2 and Figure 3 The lower surface of the I-shaped plate 500 has two symmetrical strip grooves. The inner wall of the strip groove is rotatably equipped with a bidirectional lead screw 604. The top ends of the two clamping plates 601 are slidably connected to the inner wall of the strip groove, and the surfaces of the two clamping plates 601 are threaded holes that are threaded to the outer surface of the bidirectional lead screw 604.

[0019] Specifically, by setting a bidirectional lead screw 604, the rotation of the bidirectional lead screw 604 can drive the two clamping plates 601 to move towards the middle simultaneously.

[0020] See Figure 3 and Figure 4 The interior of the I-shaped plate 500 has a rectangular cavity, and the inner wall of the rectangular cavity is rotatably provided with a bidirectional threaded post 605. The two ends of the bidirectional threaded post 605 extend into the interior of two strip grooves respectively. The ends of the bidirectional threaded post 605 and the surface of the bidirectional lead screw 604 are both fixed with a first bevel gear 606 that meshes with each other.

[0021] Specifically, by setting the first bevel gear 606, the rotation of the bidirectional threaded column 605 can drive the bidirectional lead screw 604 to rotate automatically.

[0022] See Figure 3The inner top wall of the rectangular cavity is rotatably provided with a rotating shaft extending to the upper surface of the I-shaped plate 500. The rotating disk 603 is fixed at the top of the rotating shaft, and the bottom end of the rotating shaft and the surface of the bidirectional threaded column 605 are both fixed with a second bevel gear 607 that meshes with each other.

[0023] Specifically, by setting a second bevel gear 607, the rotation of the rotating disk 603 can drive the bidirectional threaded column 605 to rotate automatically.

[0024] In this invention, by setting a positioning component 600, during the installation of the carbon canister solenoid valve body 100, after the inlet pipe and exhaust pipe are respectively inserted and fixed to the inlet end 200 and outlet end 300 of the carbon canister solenoid valve body 100, the rotating disk 603 can be rotated by an external hexagonal wrench. The rotation of the rotating disk 603 drives the bidirectional threaded column 605 to rotate under the action of two second bevel gears 607, and the rotation of the bidirectional threaded column 605 drives the two first bevel gears 606 to rotate. The rotation of the bidirectional lead screw 604 causes the two clamping plates 601 to move towards the center simultaneously. This allows the four clamping plates 601 in the two sets to effectively clamp and fix the air inlet pipe inserted into the surface of the air inlet end 200 and the air outlet pipe inserted into the surface of the air outlet end 300. This effectively ensures the stability of the air inlet pipe and the air outlet pipe after they are inserted into the air inlet end 200 and the air outlet end 300, avoids the situation of falling off and leaking, and ensures the service life of the carbon canister solenoid valve body 100.

[0025] See Figure 3 and Figure 5 Both the air inlet end 200 and the air outlet end 300 are provided with sealing components 700. The sealing components 700 include two annular grooves respectively opened on the surfaces of the air inlet end 200 and the air outlet end 300, and the inner walls of the two annular grooves are fixed with expansion airbag rings 701.

[0026] Specifically, by setting the inflatable airbag ring 701, the gaps between the air inlet pipe and the air inlet end 200, and between the air outlet pipe and the air outlet end 300, can be effectively sealed.

[0027] See Figure 3 and Figure 5 Two symmetrical fixing plates are fixed on the lower surface of the I-shaped plate 500, and an inflatable airbag column 702 is fixed on the surface of the fixing plate. The end of the inflatable airbag column 702 is provided with a connecting pipe 703 extending into the interior of an inflatable airbag ring 701. The surfaces of the two inflatable airbag rings 701 are provided with a connecting pipe 704 for connecting the two inflatable airbag rings 701.

[0028] Specifically, by setting up connecting pipe 703 and connecting pipe 704, the air inside the inflatable airbag column 702 can be compressed and enter an inflatable airbag ring 701 through connecting pipe 703, and the two inflatable airbag rings 701 can be inflated simultaneously under the action of connecting pipe 704.

[0029] See Figure 4 and Figure 5 The lower surface of the I-shaped plate 500 has two symmetrical strip openings that extend into the rectangular cavity. A pressure plate 705 is slidably disposed on the inner wall of the strip opening. The surface of the pressure plate 705 has a threaded hole that is threaded to the outer surface of the bidirectional threaded column 605. The end of the inflatable airbag column 702 is fixedly connected to the surface of the pressure plate 705. A return spring 706 is fixedly disposed inside the inflatable airbag column 702.

[0030] Specifically, by setting the pressure plate 705, the rotation of the bidirectional threaded column 605 can drive the pressure plate 705 to automatically press the inflatable airbag column 702, and at the same time, the setting of the reset spring 706 facilitates the reset of the inflatable airbag column 702.

[0031] In this invention, by setting a sealing component 700, during the rotation of the bidirectional threaded column 605, two pressure plates 705 can be driven to move to both sides simultaneously, causing the pressure plates 705 to compress the inflatable airbag column 702. This allows the gas inside the inflatable airbag column 702 to enter the interior of an inflatable airbag ring 701 through the connecting pipe 703. Under the action of the connecting pipe 704, both inflatable airbag rings 701 expand simultaneously, effectively pressing against the inner wall of the inlet or outlet pipe. This achieves effective sealing of the gap between the inlet pipe and the inlet end 200, and between the outlet pipe and the outlet end 300, further preventing leakage.

[0032] Working Principle: When installing the carbon canister solenoid valve body 100, after the inlet pipe and exhaust pipe are respectively inserted and fixed to the inlet end 200 and outlet end 300 of the carbon canister solenoid valve body 100, the rotating disk 603 can be rotated by an external hex wrench. The rotation of the rotating disk 603 drives the bidirectional threaded column 605 to rotate under the action of two second bevel gears 607. The rotation of the bidirectional threaded column 605 drives the bidirectional lead screw 604 to rotate under the action of two first bevel gears 606. The rotation of the bidirectional lead screw 604 drives the two clamping plates 601 to move towards the center simultaneously, so that the four clamping plates 601 in the two sets can effectively clamp and fix the inlet pipe inserted into the surface of the inlet end 200 and the outlet pipe inserted into the surface of the outlet end 300, thereby effectively... This ensures the stability of the inlet and outlet pipes after they are connected to the inlet end 200 and outlet end 300, preventing them from falling off and leaking. It also ensures the service life of the carbon canister solenoid valve body 100. Moreover, during the rotation of the bidirectional threaded column 605, it can drive the two pressure plates 705 to move to both sides simultaneously, causing the pressure plates 705 to compress the inflation bladder column 702. This allows the gas inside the inflation bladder column 702 to enter the interior of an expansion bladder ring 701 through the connecting pipe 703. Under the action of the connecting pipe 704, the two expansion bladder rings 701 expand simultaneously, effectively pressing against the inner wall of the inlet or outlet pipe. This achieves an effective seal between the inlet pipe and the inlet end 200, and between the outlet pipe and the outlet end 300, further preventing leakage.
