Description
Technical Field
[0001] The utility model relates to the field of vehicle-mounted air purification, in particular to a vehicle-mounted fresh air system. Background Art
[0002] The fresh air system is an independent air treatment system consisting of an air supply system and an exhaust system. It is divided into two types: ducted fresh air system and ductless fresh air system. The ducted fresh air system consists of a fresh air fan and duct accessories. The fresh air fan purifies the outdoor air and introduces it into the room, and exhausts the indoor air through the duct; the ductless fresh air system consists of a fresh air fan, which also purifies the outdoor air and introduces it into the room. Relatively speaking, the ducted fresh air system is more suitable for industrial or large-area office areas due to the large amount of work, while the ductless fresh air system is more suitable for home use because it is easy to install.
[0003] Most of the existing in-vehicle air purification industry still uses traditional meltblown cloth or air conditioning grids made of electrostatic cotton and activated carbon for filtering. To achieve the filtering effect of CN95, high-performance meltblown cloth of 95 or above must be used. Then its pressure drop will be very high, resulting in small air output (the air flow of the air conditioner at the same gear becomes much smaller), and it is still unable to filter tiny particles below 0.3 microns (ultra-small particles cannot be filtered).

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vehicle-mounted fresh air system, comprising a main frame, an air intake net is fixedly connected inside the main frame, a negative ion module is fixedly connected inside the air intake net, a conductive wire is slidably connected inside the negative ion module, a conductive sheet 1 is fixedly connected inside the main frame, the conductive wire and the conductive sheet 1 are electrically connected, a conductive sheet 2 is fixedly connected inside the main frame, the conductive sheet 1 and the conductive sheet 2 are electrically connected, a fixed sheet is slidably connected inside the main frame, a fixed frame is slidably connected inside the main frame, a filter is fixedly connected inside the fixed frame, and an installation component is provided on the outer wall of the fixed frame.
[0006] Furthermore, the installation assembly includes an insert block, and an outer wall of the insert block is fixedly connected to an outer wall of the fixing frame.
[0007] Furthermore, a pull rod is slidably connected inside the main frame, and one end of the pull rod is fixedly connected to a pull ring.

[0009] Furthermore, a push rod is slidably connected inside the insert block, and a second fixing plate is fixedly connected to the outer wall of the push rod.
[0010] Furthermore, a second spring is sleeved on the outer wall of the push rod, one end of the second spring is fixedly connected to the outer wall of the second fixing plate, and the other end of the second spring is fixedly connected to the inside of the plug block.
[0011] Furthermore, the outer wall of the push rod is rotatably connected to a connecting seat, and the outer wall of the connecting seat is slidably connected to a clamping block.
[0012] Furthermore, the outer wall of the clamping block is fixedly connected to the limiting block, and the outer wall of the limiting block is slidably connected to the inside of the inserting block.
[0013] The utility model has the following beneficial effects:
[0014] 1. In the utility model, firstly, the conductive sheet 1 is connected to a power source, so that the filter screen and the negative ion module connected to the conductive sheet 2 and the conductive wire can be charged, wherein the filter screen can electrostatically adsorb fine particles, and then the negative ion module is powered on to generate negative ions. When ventilation is performed, the negative ions can enter the car with fresh air. Negative ions are beneficial to health, thereby improving the comfort level in the car, and solving the problem that the existing fresh air system has high filtration but small air volume and cannot filter ultra-small particles.
[0015] 2. In the utility model, the pull rod is pulled out of the plug block by pulling the pull ring, and at the same time, the spring rebounds and the push rod pulls the block back until the block slides out of the main frame, thereby achieving the effect of quickly disassembling and installing the filter. This solves the problem that most of the existing fresh air systems directly insert the filter into the frame and cannot fix the filter, and improves the convenience of cleaning and replacing the filter.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Reference Figure 1-Figure 3 The utility model provides an embodiment: a vehicle-mounted fresh air system, comprising a main frame 1, an air intake net 2 is fixedly connected inside the main frame 1, a negative ion module 3 is fixedly connected inside the air intake net 2, a conductive wire 4 is slidably connected inside the negative ion module 3, a conductive sheet 1 5 is fixedly connected inside the main frame 1, the conductive wire 4 and the conductive sheet 1 5 are electrically connected, a conductive sheet 2 6 is fixedly connected inside the main frame 1, the conductive sheet 1 5 and the conductive sheet 2 6 are electrically connected, a fixed sheet 7 is slidably connected inside the main frame 1, a fixed frame 8 is slidably connected inside the main frame 1, a filter screen 9 is fixedly connected inside the fixed frame 8, and an installation component is provided on the outer wall of the fixed frame 8;
[0024] Specifically, when it is necessary to filter impurities, by connecting the conductive wire 4 to a power source, the conductive sheet 5 can receive the current and transfer it to the fixed frame 8. This process makes the surface of the filter 9 charged, so that it can effectively adsorb fine impurities and particles. At the same time, activated carbon is also arranged inside the filter 9, which enables the filter 9 to not only remove particulate matter, but also filter odors in the airflow, thereby improving the quality of the air in the car and creating a fresher driving environment. In addition, the conductive wire 4 also guides the current to the air intake network 2 through the negative ion module 3, so that the air intake network 2 can also perform preliminary electrostatic filtration, which ensures that the airflow in the car is fully filtered, reduces pollutants in the air, and improves the comfort and health level in the car.
[0025] Reference Figure 1 , Figure 2and Figure 4 , the installation assembly includes an insert block 14, the outer wall of the insert block 14 is fixedly connected to the outer wall of the fixed frame 8; the main frame body 1 is slidably connected to a pull rod 10, one end of the pull rod 10 is fixedly connected to a pull ring 11; the outer wall of the pull rod 10 is fixedly connected to a fixed plate 12, the outer wall of the pull rod 10 is sleeved with a spring 13, one end of the spring 13 is fixedly connected to the outer wall of the fixed plate 12, and the other end of the spring 13 is fixedly connected to the inside of the main frame body 1; the insert block 14 is slidably connected to a push rod 15, the outer wall of the push rod 15 is fixedly connected to a fixed plate 2 16; the outer wall of the push rod 15 is sleeved with a spring 2 17, one end of the spring 2 17 is fixedly connected to the outer wall of the fixed plate 2 16, and the other end of the spring 2 17 is fixedly connected to the inside of the insert block 14; the outer wall of the push rod 15 is rotatably connected to a connecting seat 18, and the outer wall of the connecting seat 18 is slidably connected to a card block 19; the outer wall of the card block 19 is fixedly connected to a limiting block 20, and the outer wall of the limiting block 20 is slidably connected to the inside of the insert block 14;
[0026] Specifically, when the filter 9 needs to be removed, by pulling the pull ring 11, the pull rod 10 drives the fixed plate 12 to compress the spring 13. At the same time, the pull rod 10 slides out from the inside of the plug block 14, so that the spring 2 17 is no longer compressed by the fixed plate 2 16. In this way, the elastic force of the spring 2 17 will pull back the push rod 15, and the push rod 15 will pull back the block 19 through the connecting seat 18 until the block 19 completely slides out of the main frame 1. This allows the fixed frame 8 to slide out from the inside of the main frame 1, thereby realizing the rapid disassembly of the filter 9, which improves the convenience of cleaning and replacing the filter 9, makes the maintenance and servicing process simpler and smoother, and also improves the user's operating efficiency and enhances the maintainability and durability of the entire system.
[0027] Working principle: When impurities need to be filtered, the conductive wire 4 is connected to the power supply so that the conductive sheet 1 5 can receive the current and transmit it to the fixed frame 8 through the conductive sheet 2 6, so that the surface of the filter 9 can be charged to adsorb fine impurities and particles. At the same time, the filter 9 is provided with activated carbon inside, so that the filter 9 can filter the odor contained in the incoming airflow, thereby improving the air quality. At the same time, the conductive wire 4 guides the current from the negative ion module 3 to the air intake network 2, so that the air intake network 2 can also perform preliminary electrostatic filtration, thereby achieving the effect of fully filtering the wind flow and improving the vehicle The comfort inside is improved. When the filter 9 needs to be disassembled, the pull ring 11 is pulled by the pull rod 10 to drive the fixed plate 12 to compress the spring 13, and the pull rod 10 slides out from the inside of the plug block 14, so that the spring 2 17 is no longer compressed by the fixed plate 2 16, and then the push rod 15 is pulled back by the elastic force, so that the push rod 15 can be pulled back by the connecting seat 18 to the block 19 until the block 19 completely slides out of the main frame 1, so that the fixed frame 8 can slide out of the main frame 1, thereby achieving the effect of quickly disassembling and installing the filter 9, and improving the convenience of cleaning and replacing the filter 9.
