[0002] The hydrogen injector is the core hydrogen supply component of the hydrogen fuel internal combustion engine system. It mainly uses an electromagnetic coil to control the needle valve to achieve the effect of controlling the hydrogen flow and pressure. The hydrogen injection method can be divided into intake port injection and direct injection into the cylinder. Among them, the intake port injection system has a lower cost, but it is prone to backfire and has low thermal efficiency. The direct injection into the cylinder system can make full use of the hydrogen supply components of the existing fuel cell system, and at the same time can use the free pressure of the hydrogen cylinder to reduce pressure to achieve the effective supply of hydrogen. In order to improve the efficiency of the hydrogen injector, therefore, a fast-response hydrogen injection device is particularly needed.
[0003] Because most of the existing hydrogen injectors do not have the function of fast response. When using hydrogen, due to the lack of equipment that can respond quickly, hydrogen cannot be supplied and cut off in time, resulting in the problem that the hydrogen flow is difficult to control. Content of the Utility Model
[0004] The purpose of the utility model is to provide a fast-response hydrogen injection device to solve the problem that most of the existing hydrogen injectors do not have the function of fast response. When using hydrogen, due to the lack of equipment that can respond quickly, hydrogen cannot be supplied and cut off in time, resulting in the problem that the hydrogen flow is difficult to control as mentioned in the above background technique.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution: a rapid response hydrogen injection device, including a hydrogen injector 1, a rapid response mechanism 2 is arranged on the lower surface of the hydrogen injector 1, and an adjustment mechanism 3 is arranged on one side surface of the hydrogen injector 1;
[0021] The quick response mechanism 2 includes a pipeline 201, a sealing ring 202, a thermocouple 203, a controller 204, a first wire 205, and a solenoid valve 206. The lower surface of the hydrogen injector 1 is fixedly connected to the pipeline 201. A sealing ring 202 is fixedly installed on one side surface of the pipeline 201. A thermocouple 203 is fixedly connected to one side surface of the pipeline 201. The lower surface of the thermocouple 203 is fixedly connected to the controller 204. The lower surface of the controller 204 is fixedly connected to the first wire 205. One end surface of the first wire 205 is fixedly connected to the solenoid valve 206. Through the settings of the pipeline 201, the sealing ring 202, the thermocouple 203, the controller 204, the first wire 205, and the solenoid valve 206, when in use, when the hydrogen injector 1 needs to be used, first, the pipeline 201 can be installed below the hydrogen injector 1. The pipeline 201 can play a role in transporting hydrogen. Then, the sealing ring 202 is used to connect the pipeline 201 and the hydrogen injector 1. The sealing ring 202 can not only fix the position of the pipeline 201 but also seal the hydrogen in the pipeline 201 to avoid the danger of explosion caused by hydrogen leakage. At this time, the power supply can be turned on. After the thermocouple 203 is powered on, it can detect the temperature in the pipeline 201. When the detected temperature is inconsistent with the temperature set on the controller 204, an electrical signal can be output to the controller 204. After receiving the electrical signal, the controller 204 can control the solenoid valve 206 through the first wire 205. When the solenoid valve 206 is powered on, the magnetic field will open the valve, and the gas can flow through the valve to achieve the blowing function. When the solenoid valve 206 is powered off, the magnetic field disappears, the valve closes, and the gas flow is blocked to achieve the suction function. By controlling the on and off time of the solenoid valve 206, the control of blowing and suction can be achieved, so as to achieve a quick response to hydrogen.
[0022] Further, the adjusting mechanism 3 includes a plug 301, a second wire 302, a fixed housing 303, a motor 304, an inverter 305, and a potentiometer 306. On one side surface of the hydrogen injector 1, a plug 301 is fixedly installed. On one side surface of the plug 301, a second wire 302 is fixedly installed. One end surface of the second wire 302 is fixedly connected to a fixed housing 303. Inside the fixed housing 303, a motor 304 is provided. Inside the fixed housing 303, an inverter 305 is provided. Inside the fixed housing 303, a potentiometer 306 is provided. Through the settings of the plug 301, the second wire 302, the fixed housing 303, the motor 304, the inverter 305, and the potentiometer 306, when in use, when the hydrogen injector 1 needs to be used, first, the plug 301 can be inserted into the socket of the hydrogen injector 1, and then the power supply is turned on. At this time, we can control the magnitude of the analog voltage signal given to the inverter 305 by adjusting the potentiometer 306, thereby adjusting the operating frequency of the inverter 305. The rotation of the motor 304 will also perform stepless speed regulation at high speed or low speed accordingly. Finally, the fixed housing 303 can protect the motor 304, the inverter 305, and the potentiometer 306, preventing dust from falling on the surface of the electrical components and affecting the electrical components, thereby achieving the function of controlling the hydrogen flow by the magnitude of the current.
[0023] Further, the solenoid valve 206 is fixedly connected to the inner side surface of the pipeline 201. The hydrogen injector 1 is fixedly connected to the pipeline 201 through a sealing ring 202. Through the setting of the sealing ring 202, not only can the position of the pipeline 201 be fixed, but also the hydrogen in the pipeline 201 can be sealed, avoiding the danger of explosion caused by hydrogen leakage.
[0024] Further, the controller 204 is closely attached to one side surface of the hydrogen injector 1. On the other side surface of the hydrogen injector 1, a thermocouple 203 is fixedly connected. Through the setting of the thermocouple 203, the temperature inside the pipeline 201 can be detected. When the detected temperature is inconsistent with the temperature set on the controller 204, an electrical signal can be output to the controller 204.
[0025] Further, both end surfaces of the first wire 205 are respectively fixedly connected to the controller 204 and the solenoid valve 206. Both side surfaces of the pipeline 201 are respectively fixedly connected to the controller 204 and the solenoid valve 206. Through the setting of the solenoid valve 206, the control of blowing and suction can be realized, thereby achieving a rapid response to hydrogen.
[0026] Further, both end surfaces of the second wire 302 are respectively fixedly connected to the plug 301 and the motor 304. The inner side surface of the fixed housing 303 is fixedly connected to the motor 304 and the inverter 305. Through the setting of the inverter 305, the voltage and frequency can be changed, thereby realizing the variable-speed operation of the motor 304.
[0027] Further, there are three sets of second wires 302. The other side surface of the fixed housing 303 is fixedly connected to the second wires 302. Through the setting of the fixed housing 303, the motor 304, the frequency converter 305 and the potentiometer 306 can be protected, preventing dust from falling on the surface of the electrical components and affecting the electrical components.
[0028] Working principle: When in use, when the hydrogen injector 1 needs to be used, first, the pipeline 201 can be installed below the hydrogen injector 1. The pipeline 201 can play the role of transporting hydrogen. Then, the pipeline 201 and the hydrogen injector 1 are connected using the sealing ring 202. The sealing ring 202 can not only fix the position of the pipeline 201, but also seal the hydrogen in the pipeline 201, avoiding the danger of explosion caused by hydrogen leakage. At this time, the power supply can be turned on. After the thermocouple 203 is powered on, it can detect the temperature in the pipeline 201. When the detected temperature is inconsistent with the temperature set on the controller 204, an electrical signal can be output to the controller 204. After receiving the electrical signal, the controller 204 can control the solenoid valve 206 through the first wire 205. When the solenoid valve 206 is powered on, the magnetic field will open the valve, and the gas can flow through the valve to achieve the blowing function. When the solenoid valve 206 is powered off, the magnetic field disappears, the valve closes, and the gas flow is blocked to achieve the suction function. By controlling the on and off time of the solenoid valve 206, the control of blowing and suction can be realized, so as to achieve a rapid response to hydrogen. When in use, when the hydrogen injector 1 needs to be used, first, the plug 301 can be inserted into the socket of the hydrogen injector 1, and then the power supply is turned on. At this time, we can control the magnitude of the analog voltage signal given to the frequency converter 305 by adjusting the potentiometer 306, and then adjust the operating frequency of the frequency converter 305. The rotation of the motor 304 will also perform stepless speed regulation at high speed or low speed accordingly. Finally, the fixed housing 303 can protect the motor 304, the frequency converter 305 and the potentiometer 306, preventing dust from falling on the surface of the electrical components and affecting the electrical components, so as to achieve the effect of controlling the hydrogen flow by the magnitude of the current.
