Description

Technical Field

[0001] The utility model relates to the technical field of negative ions, in particular to an installation structure and an air purification device. Background Technique

[0002] As an important part of a negative ion generator, the negative ion emission end is mainly used to release negative ions. Since most negative ion emission ends are small in size, they can be more flexibly integrated into the air purification systems of various products, such as the air purification system of an automobile. Specifically, the negative ion emission end is mostly installed in the air duct of the air purification system of the automobile. The negative ion emission end can emit negative ions into the air duct, and then under the action of the fan of the air purification system, the negative ions can be transported to the interior of the automobile to ensure the air quality inside the automobile.

[0003] Currently, when installing the negative ion emission end, methods such as flange fixation, screw fixation or snap fixation are mostly used. When installing the negative ion emission end by flange fixation and screw fixation, although the connection strength of the negative ion emission end can be ensured, it is not convenient to disassemble and assemble the negative ion emission end. When installing the negative ion emission end by snap fixation, the snap is inserted into a pre-opened installation hole, and then the emission end is gently pressed to make it snap into the snap. Although the snap method is convenient for subsequent disassembly and assembly, high-frequency vibrations will occur during the driving of the automobile, and the snap may gradually loosen in a high-vibration environment, thus posing a safety hazard.

[0004] Therefore, the above problems need to be solved urgently. Content of the Utility Model

[0005] The purpose of the utility model is to provide an installation structure, an air purification device and an automobile, so as to improve the disassembly efficiency of the negative ion emission end and ensure the connection strength between the automobile emission end and the air duct.

[0006] To achieve this purpose, the utility model adopts the following technical solutions:

[0009] A first locking member, which is arranged on the negative ion emission end;

[0010] The second locking member is disposed in the air duct, and the first locking member and the second locking member can be locked to each other after the anion emission end rotates, so as to form circumferential locking of the anion emission end.

[0011] Preferably, a limiting portion is provided on the lug, which can abut against the inner wall on the downstream side of the anion emission end in the rotation direction in the side hole.

[0012] Preferably, the lug and the second locking member are respectively located on opposite side walls of the air duct.

[0034] The present utility model will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that, for the convenience of description, only the parts related to the present utility model are shown in the drawings, rather than all the structures.

[0035] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0036] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "under" and "beneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0037] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0038] Currently, when installing the negative ion emission end, methods such as flange fixation, screw fixation or snap-fastening are mostly used for installation. The methods of flange fixation and screw fixation are not convenient for disassembling and assembling the negative ion emission end, and the method of using a snap cannot ensure the safety performance during the driving of the vehicle. For this reason, in this embodiment, an installation structure for installing the negative ion emission end on the installation hole of the air duct is proposed, and the locking of the negative ion emission end is completed through two groups of linked locking structures, thereby solving the above technical problems.

[0039] Specifically, please refer to Figures 1 to 6 , the installation structure includes an ear 1, a first locking member 2 and a second locking member 3. The ear 1 is arranged on the negative ion emission end 100 and is inside the air duct 200, and the ear 1 can extend to the side hole 220 on the inner side wall of the installation hole 210. The ear 1 can be rotated through the negative ion emission end 100 and be staggeredly arranged with the side hole 220 and abut against the air duct 200 to form the axial locking of the negative ion emission end 100; the first locking member 2 is arranged on the negative ion emission end 100; the second locking member 3 is arranged on the air duct 200, and the first locking member 2 and the second locking member 3 can be locked with each other after being rotated through the negative ion emission end 100 to form the circumferential locking of the negative ion emission end 100.

[0040] It can be understood that the disassembly efficiency of the negative ion emission end 100 can be improved through the installation structure. Moreover, in a high-vibration environment, the lug 1 can abut against the air duct 200, which can not only prevent the axial movement of the negative ion emission end 100, but also prevent the first locking member 2 from disengaging from the second locking member 3. Correspondingly, when the first locking member 2 and the second locking member 3 are locked with each other, they can not only prevent the circumferential rotation of the negative ion emission end 100, but also prevent the lug 1 from separating from the air duct 200. With such a setting, the connection strength of the installation structure can be improved, and thus the safety performance can be improved.

[0041] In practical applications, before installing the ion emission end, first align the lug 1 with the side hole 220, and then place the ion emission end into the installation hole 210. The lug 1 will then enter the interior of the air duct 200. Subsequently, rotate the negative ion emission end 100, so that the lug 1 and the first locking member 2 can rotate accordingly. During the rotation process, the lug 1 can be arranged in an alternating manner with the side hole 220. After the first locking member 2 rotates to a position opposite to the second locking member 3, the two can be locked with each other, thus completing the installation of the ion emission end. When disassembling the ion emission end, rotate the ion emission end in the reverse direction.

[0042] In addition, to avoid deviation between the first locking member 2 and the second locking member 3 during the rotation of the negative ion emission end 100, in this embodiment, the installation hole 210 is preferably a round hole, and a part of the outer circumference of the housing of the negative ion emission end 100 is arc-shaped and adapted to the round hole, so as to ensure that the negative ion emission end 100 can be kept in a state of being in contact with the installation hole 210 during the rotation process.

[0043] During the actual installation process, due to different operating forces of different operators, if the operating force is too large, it may cause the first locking member 2 and the second locking member 3 to be misaligned again, resulting in the separation of the first locking member 2 and the second locking member 3, that is, the first locking member 2 and the second locking member 3 cannot lock the circumferential direction of the negative ion emission end 100.

[0044] For this reason, in this embodiment, a limiting portion 11 is provided on the lug 1, which can abut against the inner wall on the downstream side of the rotation direction of the negative ion emission end 100 in the side hole 220. It can be understood that after the lug 1 is placed in the side hole 220, there is a gap between the limiting portion 11 and the inner wall on the downstream side of the rotation direction of the negative ion emission end 100 in the side hole 220. As the negative ion emission end 100 rotates, this gap gradually decreases until it abuts against the above-mentioned inner wall, so as to feed back a signal of the rotation in place to the operator, thereby improving the accuracy of the installation structure during the installation process.

[0045] Preferably, the limiting portion 11 is a plate-shaped structure and is located on one side of the support ear 1 . During the rotation of the support ear 1 , the limiting portion 11 can gradually approach a side wall of the side hole 220 .

[0046] In this embodiment, the ear 1 and the second locking member 3 are respectively located on opposite side walls of the air duct 200. It can be understood that the mounting hole 210 and the side hole 220 are through holes, and during the installation process, the ear 1 can pass through the side hole 220, and then after rotation, the ear 1 can abut against the inner side wall of the air duct 200 to complete the axial locking of the negative ion emission end 100.

[0047] In some other feasible embodiments, the mounting hole 210 is a through hole, the side hole 220 is a blind hole, and an annular slide groove is provided at the bottom of the side hole 220. After the support ear 1 enters the side hole 220, it can enter the slide groove after rotation, so that it can abut against the side wall of the slide groove to complete the axial locking of the negative ion emission end 100.

[0048] In particular, a plurality of support ears 1 are provided, and a plurality of side holes 220 are also provided, and the plurality of support ears 1 are provided in one-to-one correspondence with the plurality of side holes 220. Such a configuration allows the support ears 1 to be uniformly stressed at all locations of the negative ion emitting end 100 when the support ears 1 axially lock the negative ion emitting end 100, thereby preventing the support ears 1 from breaking. In addition, a plurality of limiting portions 11 may also be provided, and they are provided in one-to-one correspondence with the support ears 1, so as to prevent a certain limiting portion 11 from breaking.

[0049] To ensure the sealing of the air duct 200, in this embodiment, the mounting structure also includes a pad 4, which is located between the air duct 200 and the end cover 110 of the negative ion emitting end 100, and the pad 4 can cover the mounting hole 210, thereby preventing the airflow in the air duct 200 from entering the interior of the negative ion emitting end 100.

[0050] In this embodiment, the second locking member 3 includes a groove 31 adapted to the first locking member 2, and the groove 31 is used to lock the first locking member 2. The first locking member 2 can enter the groove 31 during the rotation process, and the two side walls of the groove 31 can clamp the first locking member 2, thereby completing the circumferential locking of the negative ion emitting end 100. When the first locking member 2 vibrates at a high frequency, a slight reciprocating movement will occur, and the setting of the groove 31 can clamp the first locking member 2, thereby reducing the vibration frequency of the first locking member 2, and then ensuring that the displacement generated by the first locking member 2 during the reciprocating movement is not enough to cause it to disengage from the groove 31, thereby preventing the negative ion emitting end 100 from loosening in a high vibration environment.

[0051] To facilitate the entry of the first locking member 2 into the groove 31 during rotation, the second locking member 3 further includes a slope 32. Along the rotation direction of the negative ion emission end 100, the slope 32 is disposed on the upstream side of the groove 31, and the highest point of the slope 32 is connected to the top end of the side wall of the groove 31. During the rotation of the first locking member 2, it can contact the slope 32. As the height of the slope 32 gradually increases, the first locking member 2 can be at the top of the groove 31. The first locking member 2 continues to rotate, so that the first locking member 2 can enter the inside of the groove 31.

[0052] When disassembling the negative ion emission end 100, the operator only needs to rotate the negative ion emission end 100 forcefully in the reverse direction to disengage from the groove 31.

[0053] In this embodiment, the first locking member 2 is a lever, which is elastic and bent. The bent end of the lever can abut against the bottom of the groove 31. Among them, the depth of the groove 31 is preferably such that when the bent end abuts against the bottom of the groove 31, the bent end can bend away from the groove 31. Under the action of the elasticity of the lever itself, it can apply a force to the bottom of the groove 31, so as to further prevent the ear 1 from separating from the air duct 200, and thus ensure the connection strength of the installation structure.

[0054] It should be noted that in some other feasible embodiments, the thickness of the backing plate 4 can also be changed to ensure that the bent end can bend away from the groove 31. The thickness of the backing plate 4 can be determined according to the actual working conditions and will not be elaborated here.

[0055] Based on the above, a air purification device is also proposed in this embodiment, which includes a negative ion emission end 100, an air duct 200 and the installation structure as described above. The air purifier adapted to the above installation structure can improve the disassembly efficiency of the negative ion emission end 100, and can also ensure the connection strength between the vehicle emission end and the air duct 200, so that the air purification device can be applied to different working conditions.

[0056] Based on the above, a vehicle is also proposed in this embodiment, which includes the above air purification device. The vehicle adapted to the above air purification device can ensure the connection strength of the air purification device under different road conditions, thus avoiding potential safety hazards.

[0057] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the claims of the present utility model.
