Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to an ethanol injector with a heating function. Background Art

[0002] The main function of an injector is to atomize fuel into tiny particles and inject them into the cylinders of an engine to complete the combustion process. The fuel pump extracts fuel from the fuel tank and raises it to high pressure. Then, after filtering through a fuel filter, the fuel is delivered to the fuel rail. The injector obtains high-pressure fuel from the fuel rail and, according to the instructions of the engine control unit (ECU), injects the fuel into the cylinders of the engine through a solenoid valve or an injector nozzle.

[0003] For example, a solenoid valve injector of a Chinese utility model with the publication number CN221322569U uses a solenoid valve to precisely control the fuel injection volume and injection time through an electrical signal, thereby achieving precise fuel injection and improving the combustion efficiency and economy of the engine. However, such a structure still has the following several significant defects:

[0004] 1. In the low-temperature cold start condition of the engine, the low fuel temperature will cause the spray penetration distance of the injector to be long and the atomization quality to be poor, resulting in difficult cold start of the engine and deteriorated emissions;

[0005] 2. During the use of the injector, carbon deposits are likely to accumulate at the injection holes, causing the injection holes to be blocked, reducing the atomization effect of the injector nozzle, affecting the normal use of the injector, and the injector nozzle is usually integrally formed, which is not convenient for disassembling, cleaning, inspecting, and replacing the injector nozzle. Summary of the Invention

[0006] The utility model aims to solve one of the technical problems existing in the prior art.

[0007] The present application provides an ethanol injector with a heating function, including a housing, a valve seat assembly, a valve core rod assembly, a spring, a spring retainer, a filter screen, an O-ring, an electromagnetic coil, and an injector nozzle;

[0008] It further includes:

[0009] An installation cavity, which is arranged inside the lower end of the housing;

[0010] A heating coil, which is fixedly installed in the installation cavity;

[0011] A temperature sensor, which is fixedly installed on the outer side wall of the housing.

[0012] It further includes:

[0013] A fixing groove, which is arranged on the injector nozzle and the housing;

[0014] A fixed block, which is slidably installed in a fixed groove on the fuel injector, and one end of which is inserted into a fixed groove on the housing;

[0015] An adjusting member, which is used to slide the fixed block into or out of the fixed groove on the housing.

[0016] The adjusting member includes:

[0017] A sliding groove, which is arranged inside the fuel injector and is communicated with the fixed groove on the fuel injector;

[0018] A sliding block, which is slidably installed in the sliding groove and is fixedly connected to the fixed block;

[0019] An adjusting spring, one end of which is fixedly connected to the sliding groove and the other end of which is fixedly connected to the sliding block;

[0020] An auxiliary member, which is used to fix the sliding block in the current position.

[0021] The auxiliary member includes:

[0022] A tooth block, which is fixedly connected to the sliding block;

[0023] A first tooth groove, which is arranged on the sliding groove;

[0024] A second tooth groove, which is arranged on the sliding groove;

[0025] Wherein, the tooth block can be inserted into the first tooth groove or the second tooth groove.

[0026] When the tooth block is inserted into the first tooth groove, the fixed block is inserted into the fixed groove on the housing; when the tooth block is inserted into the second tooth groove, the fixed block completely slides out of the fixed groove on the housing.

[0027] The adjusting member further includes:

[0028] An adjusting groove, which is arranged on the outer side wall of the housing and is communicated with the sliding groove;

[0029] An adjusting block, which is slidably installed in the adjusting groove and is fixedly connected to the sliding block.

[0030] It further includes:

[0031] A coincidence groove, which is arranged on the fuel injector;

[0032] A coincidence block, which is fixedly connected to the outer side wall of the housing and can be inserted into the coincidence groove;

[0033] Wherein, when one end of the overlapping block facing away from the filter screen fits against the bottom surface of the overlapping groove, the fixing groove on the fuel injector nozzle is precisely aligned with the fixing groove on the housing.

[0034] A sealing ring is also arranged between the housing and the fuel injector nozzle.

[0035] The beneficial effects of the present utility model are as follows:

[0036] 1. Through the setting of the heating coil, when the temperature sensor detects that the external temperature is too low, the heating coil is powered on and releases a large amount of heat to heat the fuel flowing through the inner cavity, which can improve fuel injection and fuel injection atomization, and significantly enhance the cold start performance of the engine;

[0037] 2. Through the setting of the adjusting member, the operator only needs to pull the adjusting block to disassemble, clean, repair or replace the fuel injector nozzle, avoiding carbon deposition at the fuel injection holes during long-term use, maintaining the efficient operation of the fuel injector nozzle, reducing failures, extending the maintenance cycle and service life. Through the setting of the sealing ring, it can prevent fuel from flowing out through the gap between the housing and the fuel injector nozzle. Description of the Drawings

[0045] Next, in conjunction with the accompanying drawings, a detailed description will be given of an ethanol injector with a heating function provided by the embodiments of the present application through specific embodiments and their application scenarios.

[0046] Embodiment 1:

[0047] As Figure 1 、 Figure 2 shown, the embodiment of the present application provides an ethanol injector with a heating function, including a housing 1, a valve seat assembly 2, a valve core rod assembly 3, a spring 4, a spring retainer 5, a filter screen 6, an O-ring 7, an electromagnetic coil 8, and an injector nozzle 9; it further includes an installation cavity 10, which is arranged inside the lower end of the housing 1; a heating coil 11, which is fixedly installed in the installation cavity 10; and a temperature sensor 12, which is fixedly installed on the outer side wall of the housing 1.

[0048] In this embodiment of the present application, due to the above structure, the injector nozzle 9 is detachably installed at the bottom end of the housing 1, an inner cavity is arranged inside the housing 1, the filter screen 6 is fixedly installed at the upper end of the inner cavity, and the filter screen 6 is used to filter out impurities in the fuel. The valve seat assembly 2 and the spring retainer 5 are fixedly installed in the inner cavity. One end of the spring retainer 5 facing the valve seat assembly 2 is sequentially connected with the spring 4 and the valve core rod assembly 3. Among them, the valve core rod assembly 3 can slide up and down in the inner cavity, and the valve core rod assembly 3 is in close contact with the valve seat assembly 2. An electromagnetic coil 8 is also installed inside the housing. By turning the electromagnetic coil 8 on and off, the gap between the valve core rod assembly 3 and the valve seat assembly 2 can be controlled, thereby controlling its fuel injection volume and fuel injection time;

[0049] When the temperature sensor 12 detects that the external temperature is too low, the heating coil 11 is energized and releases a large amount of heat. The generated heat is transferred to the inner cavity of the housing 1 through heat transfer. When the fuel flows through the inner cavity of the housing 1, the temperature of the fuel can rise within a short time, thereby improving fuel injection and atomization, and significantly enhancing the cold start performance of the engine.

[0050] Embodiment 2:

[0051] As Figure 3 shown, in this embodiment, in addition to including the structural features of the foregoing embodiment, it further includes a fixing groove 13, which is provided on the fuel injector 9 and the housing 1; a fixing block 14, which is slidably installed in the fixing groove 13 on the fuel injector 9, and one end of which is inserted into the fixing groove 13 on the housing 1; an adjusting member 15, which is used to slide the fixing block 14 into or out of the fixing groove 13 on the housing 1.

[0052] Furthermore, the adjusting member 15 includes a sliding groove 151, which is provided inside the fuel injector 9 and communicates with the fixing groove 13 on the fuel injector 9; a sliding block 152, which is slidably installed in the sliding groove 151 and is fixedly connected to the fixing block 14; an adjusting spring 153, one end of which is fixedly connected to the sliding groove 151 and the other end of which is fixedly connected to the sliding block 152; an auxiliary member 154, which is used to fix the sliding block 152 in the current position.

[0053] Furthermore, the auxiliary member 154 includes a tooth block 155, which is fixedly connected to the sliding block 152; a first tooth groove 156, which is provided on the sliding groove 151; a second tooth groove 157, which is provided on the sliding groove 151; wherein, the tooth block can be inserted into the first tooth groove 156 or the second tooth groove 157.

[0054] Furthermore, when the tooth block 155 is inserted into the first tooth groove 156, the fixing block 14 is inserted into the fixing groove 13 on the housing 1. When the tooth block 155 is inserted into the second tooth groove 157, the fixing block 14 completely slides out of the fixing groove 13 on the housing 1.

[0055] Furthermore, the adjusting member 15 further includes an adjusting groove 158, which is provided on the outer side wall of the housing 1 and communicates with the sliding groove 151; an adjusting block 159, which is slidably installed in the adjusting groove 158 and is fixedly connected to the sliding block 152.

[0056] Further, it further includes a coincidence groove 161 provided on the fuel injector 9; a coincidence block 162 fixedly connected to the outer side wall of the housing 1 and insertable into the coincidence groove 161; wherein when the end of the coincidence block 162 facing away from the filter screen 6 fits against the bottom surface of the coincidence groove 161, the fixing groove 13 on the fuel injector 9 is precisely aligned with the fixing groove 13 on the housing 1.

[0057] Further, a sealing ring 16 is also provided between the housing 1 and the fuel injector 9.

[0058] In this embodiment of the present application, due to the above structure, when the fuel injector 9 needs to be disassembled, the adjusting block 159 can be pulled outward, the adjusting block 159 drives the sliding block 152 to slide in the direction of the spring 153 and compresses the adjusting spring 153. Since the tooth block 155 is made of rubber material, the tooth block 155 will deform under the action of the extrusion force until the tooth block 155 reaches the second tooth groove 157, and then the tooth block 155 elastically resumes its shape. At this time, the tooth block 155 will fix the sliding block 152 in the current position, and the fixing block 14 completely slides out of the fixing groove 13 on the housing 1, and the operator can take out the fuel injector 9, which is convenient for cleaning the fuel injection holes on the fuel injector 9 or overhauling the fuel injector 9;

[0059] When the fuel injector 9 needs to be reinstalled, align the coincidence groove 161 on the fuel injector 9 with the coincidence block 162 on the housing 1, push the fuel injector 9 until the end of the coincidence block 162 facing away from the filter screen 6 fits against the bottom surface of the coincidence groove 161. At this time, the fixing groove 13 on the fuel injector 9 is precisely aligned with the fixing groove 13 on the housing 1. Then push the adjusting block 159 inward, the adjusting block 159 drives the sliding block 152 to slide inward, and the tooth block 155 re-enters the first tooth groove 156 from the second tooth groove 157, and the fixing block 14 is inserted into the fixing groove 13 on the housing 1, thus completing the installation operation of the fuel injector 9;

[0060] Under the combined action of the elastic force of the adjusting spring 153 and the clamping force of the tooth block 155 engaged in the first tooth groove 157, the fuel injector 9 is not likely to fall off during use;

[0061] A sealing ring 17 is also provided between the housing 1 and the fuel injector 9, and the sealing ring 17 plays a sealing role to prevent fuel from flowing out through the gap between the housing 1 and the fuel injector 9.

[0062] It should be noted that in this text, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising one..." does not exclude the existence of additional identical elements in the process, method, article or device comprising that element. In addition, it should be pointed out that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in the reverse order according to the functions involved.
