Description
Technical Field
[0001] This application relates to the field of cleaning equipment technology, and in particular to a dust removal device for an automotive intake system and the automotive intake system thereof. Background Technology
[0002] The intake system, a crucial component of a car's operation, primarily provides the engine with sufficient, clean, and dry air to ensure its normal functioning. However, in spring, large amounts of poplar and willow catkins float in the air in northern China, resulting in the intake system drawing in air containing significant dust and impurities. This not only significantly increases the risk of blockage in the intake system but also increases intake resistance, reducing the amount of air supplied to the engine. Consequently, this leads to increased fuel consumption and decreased power, and also makes cleaning clogged air filters difficult. Currently, a catkin-filtering mesh is typically added to the intake system inlet to block the catkins. However, this mesh increases intake resistance, hindering the system's performance, and it is also prone to clogging and difficult to clean. Summary of the Invention
[0003] Therefore, it is necessary to provide a dust removal device for an automotive intake system and an automotive intake system to address the problem of poor air quality inhaled by the intake system.
[0004] A dust removal device for an automotive intake system, the dust removal device for the automotive intake system comprising:
[0005] The mounting structure has an air inlet and an air outlet. The mounting structure is used to connect the airflow channel of the air intake system through the air outlet. Airflow enters the mounting structure through the air inlet and enters the airflow channel through the air outlet.
[0006] A dust collection module includes an electrostatic adsorption panel. When the electrostatic adsorption panel is energized, it forms a high-voltage electrostatic field. The electrostatic adsorption panel is disposed between the air inlet and the air outlet so that the airflow passes through the high-voltage electrostatic field when flowing from the air inlet to the air outlet.
[0007] Through the above technical solution, the mounting structure can be a structural component of the automotive intake system itself, such as an intake base or intake channel. Using this mounting structure as the mounting carrier for the dust removal device of the automotive intake system gives the dust removal device strong installation adaptability, allowing it to adapt to various models and structures of automotive intake systems, thus reducing the installation space required for the dust removal device. A high-voltage electrostatic field is formed on the electrostatic adsorption panel. When airflow containing impurities and dust flows from the intake port to the outlet, it passes through this high-voltage electrostatic field. In this field, airflow molecules are ionized into positive ions and electrons. As electrons travel towards the positive electrode, they encounter dust and impurities. These impurities and dust combine with negative ions and become negatively charged, then tend to discharge towards the anode surface, causing the dust and impurities to become negatively charged and adsorbed onto the positive electrode, thus depositing on the surface of the electrostatic adsorption panel. This dust removal process does not increase the intake resistance of the intake system, has high dust removal efficiency, and is easy to clean.
[0008] In one embodiment, the mounting structure has an auxiliary airflow port on its inner sidewall near the air inlet, and the electrostatic adsorption panel is disposed on the inner sidewall of the mounting structure opposite to the auxiliary airflow port, so that the airflow entering from the air inlet approaches the electrostatic adsorption panel under the airflow guidance of the auxiliary airflow port.
[0009] With the above technical solution, after the airflow enters the mounting structure through the air inlet, an auxiliary airflow port is opened on the side of the mounting structure. An electrostatic adsorption panel is set at the position opposite to the auxiliary airflow port. The airflow entering from the auxiliary airflow port will guide the airflow entering from the air inlet from the side, so that the airflow entering from the air inlet is closer to the electrostatic adsorption panel and is more easily affected by the high voltage electrostatic field, so as to thoroughly deposit dust and impurities in the airflow and improve the dust removal efficiency of the dust removal device of the car intake system.
[0010] In one embodiment, the dust removal device of the vehicle intake system further includes a cleaning module, the cleaning module including a water spray nozzle, the water spray nozzle being disposed at one end of the electrostatic adsorption panel near the air intake, the water spray nozzle being used to clean the electrostatic adsorption panel.
[0011] With the above technical solution, when the dust and impurities deposited on the surface of the electrostatic adsorption panel reach a certain level, the dust removal performance of the electrostatic adsorption panel will be weakened. At this time, the electrostatic adsorption panel can be cleaned in time by spraying water. The clean water directly washes away the dust and impurities from the electrostatic adsorption panel, resulting in good cleaning effect and high cleaning efficiency.
[0012] In one embodiment, the cleaning module further includes a water tank, a water pipe, and an on / off valve. The water spray nozzle is connected to the water tank through the water pipe. The on / off valve is provided between the water pipe and the water tank. The on / off valve is used to communicate with the vehicle's central control system and to control the opening and closing of the on / off valve through the vehicle's central control system.
[0013] With the above technical solution, when the cleaning module is not in operation, the on / off valve is closed and the water pipe and the water storage tank are not connected. When the cleaning module is in operation, the on / off valve is open and the water pipe and the water storage tank are connected, supplying water from the water storage tank to the spray nozzles.
[0014] In one embodiment, the dust collection module further includes a cleanliness sensor disposed on the electrostatic adsorption panel. The cleanliness sensor is used to communicate with the vehicle's central control system. When the cleanliness sensor detects that the amount of dust on the electrostatic adsorption panel reaches an alarm value, the vehicle's central control system controls the opening of the on / off valve to perform a cleaning operation.
[0015] By installing a cleanliness sensor to monitor the cleanliness of the electrostatic adsorption panel in real time, the vehicle's main control system can control the opening and closing of the on / off valve to clean the electrostatic adsorption panel when the alarm value is reached, thus realizing an automated cleaning mode for the dust removal device of the vehicle's air intake system.
[0016] In one embodiment, the cleaning module further includes a one-way valve and a high-pressure device. The one-way valve is installed on the upper part of the water storage tank, and the water storage tank is connected to the high-pressure device through the one-way valve. When the on / off valve is in the open state, the high-pressure device pressurizes water into the water pipe.
[0017] Through the above technical solution, a certain gas phase space is left at the top of the water storage tank. When the on-off valve is closed, the gas pressure in the water storage tank and the gas pressure in the high-pressure device are balanced. When the on-off valve is opened, the gas pressure in the water storage tank decreases, and the high-pressure device forces the water in the water storage tank into the water guide pipe to supply cleaning water to the spray nozzles. The one-way valve is used to prevent the water in the water storage tank from flowing back into the high-pressure device, ensuring the safety of the cleaning module.
[0018] In one embodiment, the cleaning module further includes a drain port, which is located at the end of the electrostatic adsorption panel away from the air inlet. The drain port is used to discharge the cleaning wastewater from the spray nozzle. The drain port includes a guide section and a drain valve. Along the direction from the spray nozzle to the drain port, the guide section has an inverted triangular structure, and a drain outlet is provided at the bottom of the inverted triangular structure. The drain valve is located at the drain outlet.
[0019] Through the above technical solution, the inverted triangular structure of the diversion part can guide the cleaning wastewater to the drain outlet. When the drain valve is open, the cleaning wastewater is discharged through the drain outlet.
[0020] In one embodiment, the dust collection module further includes a contaminant capture chamber connected and communicating with the mounting structure. The contaminant capture chamber includes a mounting wall opposite to the mounting structure, an upper mounting portion near the air inlet, and a lower mounting portion away from the air inlet. The electrostatic adsorption panel is disposed on the mounting wall, the water spray nozzle is disposed on the upper mounting portion, and the sewage discharge port is disposed on the lower mounting portion.
[0021] Through the above technical solution, the pollutant capture chamber is used to provide installation space for the electrostatic adsorption panel and the water spray nozzle and sewage discharge port of the cleaning module.
[0022] In one embodiment, the dust collection module further includes an electrostatic generator and a self-excited oscillator. The electrostatic adsorption panel is electrically connected to the electrostatic generator. The electrostatic generator includes a connection port for connecting to the vehicle's power supply. The electrostatic generator converts the low-voltage DC output from the power supply into high-voltage DC through the self-excited oscillator to form a high-voltage electrostatic field on the electrostatic adsorption panel.
[0023] Through the above technical solution, the electrostatic generator can automatically enter the working state after the power supply is turned on. It forms a high-voltage electrostatic field on the surface of the electrostatic adsorption panel through the self-excited oscillator, so as to realize the automatic start-up and operation of the dust removal device of the car intake system.
[0024] This application also proposes an automotive intake system, the automotive intake system comprising:
[0025] The main body of the car's air intake system;
[0026] The dust removal device for the aforementioned automotive air intake system.
[0027] In the technical solution of this application, the mounting structure can be a structural component of the automotive intake system itself, such as an intake base or intake channel. Using the mounting structure as the mounting carrier for the dust removal device of the automotive intake system gives the dust removal device of the automotive intake system strong installation adaptability, so as to adapt to various models and different structures of automotive intake systems, and reduce the installation space required for the dust removal device of the automotive intake system. A high-voltage electrostatic field is formed on the electrostatic adsorption panel. When the airflow containing impurities and dust flows from the air inlet to the air outlet, it passes through the high-voltage electrostatic field. In the high-voltage electrostatic field, the airflow molecules are ionized into positive ions and electrons. When the electrons encounter dust and impurities on their way to the positive electrode, the impurities and dust combine with the negative ions and become negatively charged. They then tend to discharge at the anode surface, causing the dust and impurities to become negatively charged and adsorbed to the positive electrode, thus depositing on the surface of the electrostatic adsorption panel. The dust removal process does not increase the intake resistance of the intake system and has high dust removal efficiency, making it easy to clean. Attached Figure Description

[0041] See Figures 1 to 5 , Figures 1 to 4The diagrams show front, side, rear, top, and axonometric views of the dust removal device 1000 for an automotive intake system according to this application. This application proposes a dust removal device 1000 for an automotive intake system, which includes a mounting structure 100 and a suction module 200. The mounting structure 100 has an air inlet 110 and an air outlet 120. The mounting structure 100 is used to connect to the airflow channel 500 of the intake system through the air outlet 120. Airflow enters the mounting structure 100 through the air inlet 110 and enters the airflow channel 500 through the air outlet 120. The suction module 200 includes an electrostatic adsorption panel 210. When energized, the electrostatic adsorption panel 210 forms a high-voltage electrostatic field. The electrostatic adsorption panel 210 is positioned between the air inlet 110 and the air outlet 120 so that the airflow passes through the high-voltage electrostatic field as it flows from the air inlet 110 to the air outlet 120. The mounting structure 100 can be a structural component of the automotive intake system 2000 itself, such as an intake base or intake channel. Using the mounting structure 100 as the mounting carrier for the dust removal device 1000 of the automotive intake system gives the dust removal device 1000 strong installation adaptability, allowing it to accommodate various models and structures of automotive intake systems 2000, thus reducing the installation space required for the dust removal device 1000. It should be noted that the mounting structure 100 must be located in front of the air filter of the automotive intake system 2000. A high-voltage electrostatic field is formed on the electrostatic adsorption panel 210. When the airflow containing impurities and dust flows from the air inlet 110 to the air outlet 120, it passes through the high-voltage electrostatic field. In the high-voltage electrostatic field, the airflow molecules are ionized into positive ions and electrons. As the electrons rush towards the positive electrode, they encounter dust and impurities. The impurities and dust combine with the negative ions and become negatively charged. They then tend to discharge at the anode surface, causing the dust and impurities to become negatively charged and be adsorbed onto the positive electrode, thus depositing on the surface of the electrostatic adsorption panel 210. The dust removal process does not increase the air intake resistance of the air intake system and has high dust removal efficiency, making it easy to clean.
[0042] See Figure 3The mounting structure 100 has an auxiliary airflow port 130 on its inner wall near the air inlet 110. An electrostatic adsorption panel 210 is disposed on the inner wall of the mounting structure 100 opposite to the auxiliary airflow port 130, so that the airflow entering from the air inlet 110 is guided by the airflow from the auxiliary airflow port 130 and approaches the electrostatic adsorption panel 210. The auxiliary airflow port 130 has a multi-hole air intake structure with a hole diameter ranging from φ1 to φ10 (mm). After the airflow enters the mounting structure 100 through the air inlet 110, an auxiliary airflow inlet 130 is provided on the side of the mounting structure 100. An electrostatic adsorption panel 210 is provided at the position opposite to the auxiliary airflow inlet 130. The airflow entering from the auxiliary airflow inlet 130 will be guided from the side to the airflow entering from the air inlet 110, so that the airflow entering from the air inlet 110 is closer to the electrostatic adsorption panel 210 and is more easily affected by the high voltage electrostatic field, so as to thoroughly deposit dust and impurities in the airflow and improve the dust removal efficiency of the dust removal device 1000 of the car intake system.
[0043] Furthermore, the dust removal device 1000 of the automotive intake system also includes a cleaning module 300. The cleaning module 300 includes a water spray nozzle 310, which is positioned at the end of the electrostatic adsorption panel 210 near the air intake 110. The water spray nozzle 310 is used to clean the electrostatic adsorption panel 210. For example, the water spray nozzle 310 has a small-diameter nozzle capable of spraying conical mist-like water droplets. The number of water spray nozzles 310 installed is determined according to the actual application, ensuring that the spray range of the water spray nozzles 310 covers the surface of the electrostatic adsorption panel 210; no specific limitation is made here. When dust and impurities deposited on the surface of the electrostatic adsorption panel 210 reach a certain level, it weakens the dust removal performance of the electrostatic adsorption panel 210. At this time, timely cleaning of the electrostatic adsorption panel 210 by the water spray nozzle 310 allows clean water to directly wash away the dust and impurities from the electrostatic adsorption panel 210, resulting in good cleaning effect and high cleaning efficiency.
[0044] Preferably, the surface of the electrostatic adsorption panel 210 is provided with a waterproof layer to prevent the cleaning water from the water spray nozzle 310 from causing water ingress and short circuit in the electrostatic adsorption panel 210.
[0045] Further, see Figure 1The cleaning module 300 also includes a water tank 320, a water pipe 330, and an on / off valve 340. The spray nozzles 310 are connected to the water tank 320 via the water pipe 330. An on / off valve 340 is installed between the water pipe 330 and the water tank 320. The on / off valve 340 is used for communication with the vehicle's central control system, which controls its opening and closing. The water tank 320 is made of a high-pressure resistant material. The water tank 320 can be cylindrical, elliptical, or have an irregular curved surface, etc., adaptable to the installation space available; no specific limitation is made here. The water pipe 330 is made of rigid materials such as nylon or metal, ensuring it will not deform significantly under a working pressure of 1.5 MPa. The on / off valve 340 can be connected to the vehicle's central control system via wired or wireless communication; no specific limitation is made here. For example, the control panel of the vehicle's main control system is equipped with an on / off switch, and the on / off valve 340 is connected to the on / off switch via a wire. When the cleaning module 300 is not in operation, the on / off valve 340 is in the closed state, and there is no connection between the water pipe 330 and the water tank 320. When the cleaning module 300 is in operation, the on / off valve 340 is in the open state, and there is a connection between the water pipe 330 and the water tank 320, supplying water from the water tank 320 to the spray nozzle 310.
[0046] Furthermore, the dust collection module 200 also includes a cleanliness sensor, which is mounted on the electrostatic adsorption panel 210. The cleanliness sensor is used to communicate with the vehicle's central control system. When the cleanliness sensor detects that the amount of dust on the electrostatic adsorption panel 210 reaches an alarm value, the vehicle's central control system controls the opening of the on / off valve 340 to perform a cleaning operation. By installing a cleanliness sensor to monitor the cleanliness status of the electrostatic adsorption panel 210 in real time, and by controlling the opening of the on / off valve 340 when the alarm value is reached, the electrostatic adsorption panel 210 can be cleaned, thus realizing an automated cleaning mode for the dust removal device 1000 of the vehicle's intake system.
[0047] See Figure 1The cleaning module 300 also includes a one-way valve 350 and a high-pressure device. The one-way valve 350 is installed on the upper part of the water storage tank 320, and the water storage tank 320 is connected to the high-pressure device through the one-way valve 350. When the on-off valve 340 is in the open state, the high-pressure device forces water into the water guide pipe 330. The one-way valve 350 includes a high-pressure connection port 351, through which the one-way valve 350 is connected to the high-pressure device. The upper part of the water storage tank 320 has a certain gas phase space to ensure that there is always a certain pressure inside the water storage tank 320. When the on-off valve 340 is closed, the gas pressure in the water storage tank 320 is balanced with the gas pressure in the high-pressure device. When the on-off valve 340 is opened, the gas pressure in the water storage tank 320 decreases, and the high-pressure device forces the water in the water storage tank 320 into the water guide pipe 330 to supply cleaning water to the water spray head 310. The one-way valve 350 is used to prevent the water in the water storage tank 320 from flowing back into the high-pressure device to ensure the safety of the cleaning module 300.
[0048] The water storage tank 320 also includes a water inlet cover for filling the water inlet. The connection port between the water storage tank 320 and the one-way valve 350 must be higher than the water inlet to ensure that when the water storage tank 320 is full, there is still a gas phase space at the top of the water storage tank 320, so that when the on / off valve 340 is opened, the high-pressure gas source is connected to the gas phase space inside the water storage tank 320.
[0049] Specifically, see Figure 1 The cleaning module 300 also includes a drain port 360, which is located at the end of the electrostatic adsorption panel 210 away from the air inlet 110. The drain port 360 is used to discharge the cleaning wastewater from the spray nozzles 310. The drain port 360 includes a guide section 361 and a drain valve 362. Along the direction from the spray nozzles 310 to the drain port 360, the guide section 361 has an inverted triangular structure with a drain outlet at the bottom. The drain valve 362 is located at the drain outlet. The drain valve 362 is made of aging-resistant soft rubber. When the vacuum at the drain outlet is not less than 0.1 kPa, the drain valve 362 is in a closed state; when the water level at the drain outlet is not less than 10 mm, the drain valve 362 is in an open state. The inverted triangular structure of the guide section 361 guides the cleaning wastewater to the drain outlet. When the drain valve 362 is in the open state, the cleaning wastewater is discharged through the drain outlet.
[0050] See Figure 2The dust collection module 200 also includes a contaminant capture chamber 400, which is connected to and communicates with the mounting structure 100. The contaminant capture chamber 400 includes a mounting wall 410 opposite to the mounting structure 100, an upper mounting portion 420 near the air inlet 110, and a lower mounting portion 430 away from the air inlet 110. An electrostatic adsorption panel 210 is disposed on the mounting wall 410, a water spray nozzle 310 is disposed on the upper mounting portion 420, and a drain port 360 is disposed on the lower mounting portion 430. The connection between the contaminant capture chamber 400 and the mounting structure 100 can be a non-detachable connection such as welding or blow molding, or a detachable connection such as riveting or threaded connection; no specific limitation is made here. It should be noted that a sealing connector is also included between the contaminant capture chamber 400 and the mounting structure 100 to ensure a sealed connection between the two. The contaminant capture chamber 400 provides installation space for the electrostatic adsorption panel 210 and the water spray nozzle 310 and drain port 360 of the cleaning module 300.
[0051] The dust collection module 200 also includes an electrostatic generator 220 and a self-excited oscillator. The electrostatic adsorption panel 210 is electrically connected to the electrostatic generator 220. The electrostatic generator 220 includes a power connection port 221 for connecting to the vehicle's power supply. The electrostatic generator 220 converts the low-voltage DC output from the power supply into high-voltage DC through the self-excited oscillator to form a high-voltage electrostatic field on the electrostatic adsorption panel 210. The electrostatic generator 220 is connected to the electrostatic adsorption panel 210 via a wire 230. After the power supply is turned on, the electrostatic generator 220 automatically enters the working state, forming a high-voltage electrostatic field on the surface of the electrostatic adsorption panel 210 through the self-excited oscillator, thereby realizing the automatic start-up and operation of the dust removal device 1000 of the vehicle's intake system.
[0052] This application also proposes an automotive air intake system 2000, which includes an automotive air intake system 2000 body and the aforementioned dust removal device 1000 for the automotive air intake system.
[0053] In the technical solution of this application, the mounting structure 100 can be a structural component of the automobile intake system 2000 itself, such as an intake base or intake channel. The mounting structure 100 serves as the mounting carrier for the dust removal device 1000 of the automobile intake system, giving the dust removal device 1000 strong installation adaptability to accommodate various models and structures of automobile intake systems 2000, thus reducing the installation space required for the dust removal device 1000. A high-voltage electrostatic field is formed on the electrostatic adsorption panel 210. When the airflow containing impurities and dust flows from the intake port 110 to the outlet port 120, it passes through the high-voltage electrostatic field. In the high-voltage electrostatic field, the airflow molecules are ionized into positive ions and electrons. As the electrons move towards the positive electrode, they encounter dust and impurities. The impurities and dust combine with negative ions and become negatively charged, tending to discharge towards the anode surface. This causes the dust and impurities to become negatively charged and adsorbed onto the positive electrode, thus depositing on the surface of the electrostatic adsorption panel 210. The dust removal process does not increase the intake resistance of the intake system and has high dust removal efficiency, making it easy to clean.
[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0055] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
