Description

Technical Field

[0001] The utility model relates to the technical field of air filters, in particular to an air filter for new energy vehicles. Background Art

[0002] The air filter of a new energy vehicle mainly refers to a device used to filter pollutants in the air entering the vehicle to ensure the air quality inside the vehicle. According to the search results, although new energy vehicles do not rely on internal combustion engines and do not require air for combustion, and thus do not require air filters in the traditional sense, they usually come with air conditioner filters to filter the air in the air conditioning system. The function of the air conditioner filter is to filter automobile exhaust, pollen, volatile organic compounds, PM2.5 particles, etc. to protect the respiratory health of the people inside the vehicle.

[0003] The air filter filters air through multiple layers of filter meshes. Generally, the aperture of the multiple layers of filter meshes gradually decreases from the air inlet to the air outlet. For the convenience of description, the filter meshes from the air inlet to the air outlet are sequentially defined as the first filter mesh, the second filter mesh, and the third filter mesh. Since the first filter mesh is close to the air inlet, the first filter mesh comes into contact with the most dust, and the utilization rate of the third filter mesh is the lowest. When replacing the air filter during vehicle maintenance, all the filter meshes are replaced at once, which results in the underutilization of the third and even the fourth filter meshes, causing waste.

Detailed implementation manner

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] Refer to Figures 1-4 , a new energy vehicle air filter, including a housing 10 and an air filtering component 9. The housing 10 has an air inlet 1 and an air outlet 4. The air filtering component 9 is located between the air inlet 1 and the air outlet 4. The air filtering component 9 includes a frame 5. The frame 5 has an upper opening 11 and a lower opening 12. A filter screen part 14 is provided between the upper opening 11 and the lower opening 12 of the frame 5. A mesh cloth switchable component is installed on the frame 5. The mesh cloth switchable component includes a mesh cloth 8, and the mesh cloth 8 covers the upper opening 11.

[0021] When the device works, the outside air flow enters the housing 10 through the air inlet 1, and first passes through the mesh cloth 8 of the mesh cloth switchable component for preliminary filtration. After passing through the preliminary filtration of the mesh cloth 8, it enters the filter screen part 14 for fine filtration. Finally, the filtered gas is discharged from the air outlet 4. After using for a period of time, for example, the maintenance period of the air filter is one year. Then, at 8-10 months, a layer of dust will be filtered and collected by the mesh cloth 8. A new mesh cloth 8 is switched through the mesh cloth switchable component to cover the upper opening 11. Due to the preliminary filtration of the mesh cloth 8, the amount of dust contacted by the filter screen part 14 will be reduced a lot. After replacing the new mesh cloth 8, the entire air filter can continue to be used, and the one-year maintenance period of the air filter can be extended to about one and a half to two years, effectively reducing the replacement frequency of the entire filter screen part 14 of the air filter.

[0022] To facilitate the switching of the new mesh cloth, refer to Figure 2 , Figure 3 , the mesh cloth switchable component includes a first reel 6 and a second reel 7 rotatably connected to the frame 5. The first reel 6 and the second reel 7 are respectively located on both sides of the frame 5. Both ends of the mesh cloth 8 are respectively wound around the first reel 6 and the second reel 7. The width of the mesh cloth 8 is greater than or equal to the width of the upper opening 11, and the total length of the mesh cloth 8 is at least twice the length of the upper opening 11. After using for a period of time, by actively rotating the first reel 6, the used mesh cloth is wound onto the first reel 6, and at the same time, the unused mesh cloth 8 on the second reel 7 is released to the position of the upper opening 11, which conveniently completes the switching of the new and old mesh cloth 8.

[0023] Refer to Figure 3, To facilitate the replacement of the entire mesh 8, the first reel 6 and the second reel 7 each correspond to two clamping plates 16. The clamping plates 16 are fixedly connected to the frame 5. The clamping plates 16 are provided with clamping openings 15. One side of the clamping opening 15 away from the frame 5 is open. The first reel 6 can be inserted into the clamping opening 15 of the corresponding clamping plate 16 from the open side, and the second reel 7 can be inserted into the clamping opening 15 of the corresponding clamping plate 16 from the open side. By means of a buckle, the first reel 6 and the second reel 7 are buckled into the corresponding clamping openings 15, which can not only fix the first reel 6 and the second reel 7 to the clamping plates 16, but also realize the rotational connection between the first reel 6, the second reel 7 and the clamping plates 16. The clamping opening 15 generally adopts a semi-circular opening with a superior arc structure.

[0024] Reference Figure 1 , A slotted cross recess or a slotted screwdriver recess is provided at the end of the first reel 6. An adjustment opening 13 is provided at the position of the housing 10 opposite to the end of the first reel 6. The adjustment opening 13 is provided with a detachable cover; and / or a slotted cross recess or a slotted screwdriver recess is provided at the end of the second reel 7. An adjustment opening 13 is provided at the position of the housing 10 opposite to the end of the second reel 7. The adjustment opening 13 is provided with a detachable cover. The mesh 8 is switched by inserting a screwdriver into the adjustment opening 13 and rotating the first reel 6.

[0025] Reference Figure 2 、 Figure 4 , The filter element 14 is detachably assembled with the frame 5. The filter element 14 includes a first filter, a second filter, and a third filter. The first filter is close to the upper opening 11, the third filter is close to the lower opening 12, and the second filter is located between the first filter and the third filter. The aperture of the first filter is larger than that of the second filter, and the aperture of the second filter is larger than that of the third filter.

[0026] The aperture of the mesh can be between the apertures of the first filter and the second filter, or the same as the aperture of the first filter.

[0027] Reference Figure 1 、 Figure 2 , The housing 10 includes an upper cover 2 and a lower cover 3. The upper cover 2 and the lower cover 3 are connected by buckles or screws. A chamber for installing the air filtering assembly 9 is formed between the upper cover 2 and the lower cover 3. The upper cover 2 is provided with an air inlet 1, and the lower cover 3 is provided with an air outlet 4. The lower cover 3 closes the lower opening 12 of the frame 5, and the lower opening 12 is communicated with the air outlet 4. The air inlet 1 is communicated with the upper opening 11. The upper cover 2 has a plurality of pressing columns 17. The bottom ends of the pressing columns 17 abut against the frame 5. The frame 5 of the air filtering assembly 9 is placed on the lower cover 3, and then the upper cover 2 is covered. The frame 5 is squeezed at the position of the lower cover 3 by the pressing columns 17 to prevent the air outlet 4 from being directly communicated with the chamber, ensuring that the gas is discharged from the air outlet 4 after passing through the air inlet 1, the mesh 8, and the filter element 14.
