[0030] The following will describe in detail a specific embodiment of the utility model in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the description of 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.

[0034] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of the elements listed and may also include additional elements not expressly listed.

[0035] As attached Figure 1 As shown, the utility model proposes a filter component of a vehicle-mounted air purification system, including a filter core 10, an ion generating device 20 and a connecting mechanism 30. The ion generating device 20 is detachably mounted on the filter core 10 through the connecting mechanism 30. The ion generating device 20 is used to release negative ions to adsorb impurities in the air through the negative ions, so that the impurities form larger particles that are easy to be filtered. The filter core 10 is used to filter large particle impurities combined with negative ions so that the impurities cannot be discharged with the air outlet system of the air conditioner, thereby playing a role in air purification.

[0036] During actual operation, external air enters the air conditioning system through the air inlet of the air conditioner to form airflow. Impurities in the airflow combine with negative ions generated by the ion generator 20 to form large particles. The large particles move with the airflow to the filter element 10 and are adsorbed and captured. They cannot be discharged from the air outlet with the airflow. Fresh and clean air can be discharged from the air outlet.

[0037] As attached Figure 2 As shown, the filter element body 10 includes a plurality of spacers 11 arranged at intervals, and a ventilation gap 12 is left between two adjacent spacers 11. The ventilation gap 12 is conducive to forming an air flow channel so that the air flow from the air inlet side of the filter element body 10 can pass efficiently. Figure 3 The spacer 11 is connected to a filter 13 at one end facing away from the ion generating device 20, that is, the spacer 11 is connected to a filter 13 at one end close to the air outlet side, and the filter 13 is used to adsorb and filter large particles of impurities from the air inlet side.

[0038] For ease of understanding, please see the attached Figure 3 As shown, the side of the filter element 10 on which the ion generating device 20 is installed is defined as the air inlet side, and the side of the filter element 10 on which the filter screen 13 is provided is defined as the air outlet side. The air flow is purified through the filter element 10 in the direction indicated by the arrow. The above-mentioned air inlet side and air outlet side are relative, and are intended to indicate the flow direction of the air flow, and do not mean that the air inlet side is the air inlet of the air purification system. Technicians in this field can adjust the position and number of the filter components of the utility model in the air conditioning purification system according to actual needs.

[0039] The connecting mechanism 30 includes an installation part and a fixing part. The installation part is used to connect with the ion generating device 20 to install and fix the ion generating device 20. The fixing part cooperates with the ventilation gap 12 and is used to be detachably connected with the filter element core 10. With such an arrangement, the installation position of the ion generating device 20 can be adjusted according to the specifications of the filter element core 10, so that the negative ions generated by the ion generating device 20 can be evenly distributed in the ventilation gap 12 of the filter element core 10, so as to maximize the probability of negative ions combining with impurities, thereby improving the filtration efficiency.

[0040] Optionally, the connecting mechanism 30 installs the ion generating device 20 at the middle position of the filter element core 10 .

[0041] Optionally, the number of connecting mechanisms 30 can be selected according to the specifications and dimensions of the ion generating device 20 .

[0043] For ease of description, the attached Figure 5 As shown, the length direction of the ion generating device 20 is defined as the first direction, and the width direction of the ion generating device 20 is defined as the second direction. This definition is intended to illustrate the positional relationship and movement relationship of some components, and does not mean that the ion generating device 20 can only be installed on the filter element core 10 in this orientation.

[0044] In one example of this embodiment, as shown in the attached Figure 4 As shown, the mounting portion is detachably connected to the ion generating device 20, and the mounting portion includes a first clamp arm 31 and a second clamp arm 32.

When the connecting mechanism 30 is connected to the filter element core 10, the limit member 312 overlaps the air inlet side of the spacer 11 so that the fixing part of the connecting mechanism 30 can be installed in place at one time.

[0050] In another example of this embodiment, as shown in the attached Figure 7 As shown, at least one of the first clamp arm 31 and the second clamp arm 32 is provided with a support 313 at one end close to the ion generating device 20, and the support 313 protrudes and extends along the second direction. The end of the support 313 close to the ion generating device 20 is coplanar with the installation groove 311 on the groove wall. When the first clamp arm 31 and the second clamp arm 32 are connected to the ion generating device 20, the support 313 is located on the air outlet side or the air inlet side of the ion generating device 20 and contacts the ion generating device 20. The support 313 can increase the contact area between the first clamp arm 31 and / or the second clamp arm 33 and the ion generating device 20 to improve the stability of the installation.

[0051] Optionally, the support 313 is integrally formed with the first clamping arm 31 and / or the second clamping arm 32 .

[0052] As attached Figure 4 As shown, the fixing portion includes a positioning arm 33, an adjusting arm 34 and a control member 35. One end of the positioning arm 33 is connected to the first clamping arm 31, and the other end is connected to the second clamping arm 32. One end of the adjusting arm 34 is connected to the first clamping arm 31, and the other end is connected to the control member 35. The other end of the control member 35 is connected to the second clamping arm 32. The positioning arm 33 and the adjusting arm 34 are arranged opposite to each other and spaced apart in the first direction, and both cooperate with the ventilation gap 12. The positioning arm 33 and the adjusting arm 34 are at least partially installed in different ventilation gaps 12. The control member 35 is used to adjust the position of the adjusting arm 34 relative to the positioning arm 33 in the first direction so that the positioning arm 33 and the adjusting arm 34 are connected to the filter element body 10. A plurality of spacers 11 are clamped between the positioning arm 33 and the adjusting arm 34.

[0053] Optionally, the positioning arm 33 and the adjusting arm 34 are arranged in parallel.

[0054] Combined with Figure 4 and attached Figure 5 The positioning arm 33 includes a first connecting rib 331, a second connecting rib 332 and a first clamping rib 333. One end of the first connecting rib 331 is connected to the first clamping arm 31, and the other end is connected to the first clamping rib 333. One end of the second connecting rib 332 is connected to the second clamping arm 32, and the other end is connected to the first connecting rib 331 through the first clamping rib 333. The first connecting rib 331 and the second connecting rib 332 extend from the air inlet side to the air outlet side.

Figure 2 , the first clamping rib 333 is accommodated in the ventilation gap 12.

[0055] Optionally, the first clamping rib 333 is interference fit with the ventilation gap 12 .

[0056] Optional, combined with Figure 3 And attached Figure 5 One end of the first connecting rib 331 and the second connecting rib 332 close to the first clamping rib 333 extends toward the side close to each other in the second direction, so that the size of the first clamping rib 333 in the second direction is smaller than the width size of the ion generating device 20. Such a configuration can make the spacing distance between the first clamping arm 31 and the second clamping arm 32 meet the installation requirements, so that the ion generating device 20 is clamped between the first clamping arm 31 and the second clamping arm 32, and can reduce the space shielding of the filter 13 by the first clamping rib 333 to ensure the ventilation quality and filtration quality.

[0057] Optional, as attached Figure 5 As shown, a connecting groove 334 is provided on the first clamping rib 333, and the connecting groove 334 is helpful to reduce the weight of the first clamping rib 333. In one example, the connecting groove 334 extends from the air inlet side to the air outlet side and passes through the first clamping rib 333. Such a setting can reduce the shielding area of ​​the filter 13 by the first clamping rib 333, which is helpful to ensure ventilation efficiency and filtering quality.

[0058] The shape and size of the connecting groove 334 can be set according to actual needs. In order to avoid clogging by large particles of impurities, in this example, the connecting groove 334 is set as a rectangular groove.

[0059] Optionally, the first connecting rib 331 , the second connecting rib 332 and the first clamping rib 333 are integrally formed.

[0060] Optionally, the first clamping arm 31 , the second clamping arm 32 and the positioning arm 33 are integrally formed.

[0061] Combined with Figure 4 and attached Figure 5The adjusting arm 34 includes a fixed rib 341, a movable rib 342 and a second clamping rib 343. One end of the fixed rib 341 is connected to the first clamping arm 31, and the other end is connected to the second clamping rib 343. One end of the movable rib 342 is connected to the control member 35, and the other end is connected to the fixed rib 341 through the second clamping rib 343. When the fixed part is connected to the filter element body 10, the fixed rib 341 and the movable rib 342 are at least partially accommodated in the ventilation gap 12. Figure 2 , the second clamping rib 343 is accommodated in the ventilation gap 12.

[0062] Optionally, the second clamping rib 343 is interference fit with the ventilation gap 12 .

[0063] Optional, combined with Figure 3 and attached Figure 5 The fixed rib 341 and the movable rib 342, one end of which is close to the second clamping rib 343, extend toward the side close to each other in the second direction, so that the size of the second clamping rib 343 in the second direction is smaller than the width size of the ion generating device 20. This arrangement can reduce the spatial obstruction of the second clamping rib 343 on the filter 13 to ensure the ventilation quality and filtration quality.

[0064] Optionally, a through groove (not shown in the figure) is provided on the second clamping rib 343, which is beneficial to reducing the weight of the second clamping rib 343. In one example, the through groove extends from the air inlet side to the air outlet side and passes through the second clamping rib 343. Such a configuration can reduce the blocking area of ​​the filter 13 by the second clamping rib 343, which is beneficial to ensuring ventilation efficiency and filtration quality.

[0065] Optionally, the shape and size of the through slot can be set according to actual needs.

[0066] Optionally, the fixed rib 341, the movable rib 342 and the second clamping rib 343 are integrally formed.

More specifically, one end of the control member 35 is connected to the movable rib 342. By applying an external force to the control member 35, the adjustment arm 34 can be moved relative to the positioning arm 33 to change the spacing distance between the adjustment arm 34 and the positioning arm 33. If it is defined that when the control member 35 is not subjected to an external force, the spacing distance between the positioning arm 33 and the adjustment arm 34 in the first direction is the initial spacing, when an external force is applied to the control member 35, the adjustment arm 34 moves away from the positioning arm 33 in the first direction. Figure 2The initial interval gradually increases until the first clamping rib 333 is located in a certain ventilation gap 12 and the second clamping rib 343 is located in another ventilation gap 12. At this time, a plurality of spacers 11 are sandwiched between the adjusting arm 34 and the positioning arm 33, and the fixing portion is not separated from the filter element body 10. The fixing portion is clamped on the filter element body 10 to achieve installation and fixation, and has good stability. When disassembly is required, the control member 35 only needs to be pulled out toward one end of the air inlet side. The operation is simple and convenient for maintenance and overhaul.

[0069] In one example of this embodiment, Figure 4 and attached Figure 6 The control member 35 includes a base member 351 and a deformable member 352. The base member 351 is located at both ends of the deformable member 352 and is connected to the deformable member 352. One end of the deformable member 352 is connected to the second clamping arm 32 through the base member 351, and the other end is connected to the movable rib 342 through the base member 351. The deformable member 352 can be deformed in the first direction under the action of an external force so that the initial interval between the positioning arm 33 and the adjusting arm 34 changes.

[0070] Optionally, the deformable member 352 is configured as an arc-shaped member, and the arc-shaped member protrudes in the second direction toward the side away from the second clamping arm 32. When an external force is applied to the control member 35, the central angle of the arc-shaped member increases, and the distance between the two base members 351 increases, thereby increasing the initial interval between the adjustment arm 34 and the positioning arm 35. The structure is simple, the space occupied is small, and the adjustment is convenient. In one example, the arc of the arc-shaped member is a semicircular arc.

[0071] Optionally, the base member 351 and the deformable member 352 are integrally formed.

[0072] In another example of this embodiment, as shown in the attached Figure 6 As shown, the base member 351 is provided with a clamp 3511 at one end close to the filter element body 10, and the clamp 3511 protrudes and extends toward the end close to the air outlet side. The clamp 3511 is used to cooperate with the ventilation gap 12. When the connecting mechanism 30 is installed on the filter element body 10, the clamp 3511 is installed in the ventilation gap 12 to cooperate with the positioning arm 33 and the adjustment arm 34 to improve the stability and firmness of the assembly.

[0073] Optionally, the clamp 3511 is interference fit with the ventilation gap 12 .

[0074] Optionally, the clamping member 3511 and the base member 351 are integrally formed.
