Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and particularly relates to a grounding structure and a device with a grounding structure. Background Art

[0002] Currently, electrostatic problems are prevalent in electric purification air purifiers on the market. That is, the high-voltage electricity generated by the electric purification module will make the conductors around it carry static electricity, resulting in the conductors around the electric purification module being extremely likely to adsorb dust, and at the same time, it will also interfere with the normal operation of the controller. Therefore, in product design, generally, grounding treatment is carried out on the conductors with static electricity. The currently commonly used grounding method is to connect one end of the grounding wire to the conductor with static electricity by means of screws, and the other end is connected to the ground or grounding components such as an electrical box or an electrical box cover. This connection method results in a relatively low assembly efficiency between the grounding wire and the conductor with static electricity. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defect of relatively low assembly efficiency between the grounding wire and the conductor with static electricity in the prior art, so as to provide a grounding structure and a device with a grounding structure that can improve the assembly efficiency between the connecting wire and the conductor with static electricity.

[0005] An installation body, provided with a relief through-hole;

[0006] A conductor, installed on one side of the installation body;

[0007] A conductive sheet, including a main body, an insertion piece, and at least one elastic piece; the insertion piece extends from one side of the main body in a direction away from the conductor, and is adapted to extend through the relief through-hole to the side of the installation body facing away from the conductor; the elastic piece is not coplanar with the main body, and contacts the conductor when the conductor is installed on the installation body;

[0008] A grounding wire, one end of which is electrically connected to the insertion piece, and the other end is grounded.

[0014] A contact part extends from the end of the extension part away from the main body in a direction away from the main body and is parallel to the main body.

[0015] The conductive sheet includes two such elastic sheets, which are respectively located on both sides of the main body.

[0016] A connection through hole is provided on the insertion piece.

[0017] It further includes a positioning structure adapted to position between the conductive sheet and the mounting body.

[0018] The positioning structure includes:

[0019] A positioning groove or a positioning hole is provided on one of the conductive sheet and the mounting body;

[0020] A positioning block is provided on the other of the conductive sheet and the mounting body and is adapted to be inserted into the positioning groove or the positioning hole.

[0021] The present invention also provides a device with a grounding structure, including the above-mentioned grounding structure.

[0025] 1. The grounding structure provided by the present invention includes: a mounting body provided with a relief through-hole; a conductor mounted on one side of the mounting body; a conductive sheet including a main body, an insertion piece, and at least one elastic piece; the insertion piece extends from one side of the main body in a direction away from the conductor and is adapted to extend through the relief through-hole to the side of the mounting body facing away from the conductor; the elastic piece is not coplanar with the main body and contacts the conductor when the conductor is mounted on the mounting body; a grounding wire, one end of which is electrically connected to the insertion piece and the other end is grounded. During installation, first insert the insertion piece of the conductive sheet into the relief through-hole and extend it to the side of the mounting body facing away from the conductor, then mount the conductor on the mounting body, and through the installation between the conductor and the mounting body, the clamping and fixing of the conductive sheet and the contact between the elastic piece and the conductor are realized.

Detailed Embodiments

[0037] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.

[0038] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0039] As Figures 1 - 4 shown, this embodiment provides a grounding structure, including a mounting body 1, a conductor 2, a conductive sheet, and a ground wire 4.

[0040] A relief through-hole 11 is provided on the mounting body 1.

[0041] The conductor 2 is mounted on one side of the mounting body 1.

[0042] The conductive sheet includes a main body 31, an insertion piece 32, and at least one elastic piece 33; the insertion piece 32 extends from one side of the main body 31 in a direction away from the conductor 2 and is adapted to extend through the relief through-hole 11 to the side of the mounting body 1 facing away from the conductor 2; the elastic piece 33 is not coplanar with the main body 31 and contacts the conductor 2 when the conductor 2 is mounted on the mounting body 1.

[0043] One end of the ground wire 4 is electrically connected to the insertion piece 32, and the other end is grounded.

[0044] During installation, first insert the insertion piece 32 of the conductive sheet into the relief through-hole 11 and extend it to the side of the mounting body 1 facing away from the conductor 2, then mount the conductor 2 on the mounting body 1, and through the installation between the conductor 2 and the mounting body 1, the clamping and fixing of the conductive sheet are realized, as well as the contact between the elastic piece 33 and the conductor 2. Then, connect one end of the ground wire 4 to the part of the insertion piece 32 extending to the side of the mounting body 1 facing away from the conductor 2, and the other end is grounded, that is, the installation between the components of the grounding structure is completed; at the same time, the conductor 2 is also grounded through the elastic piece 33, the main body 31, the insertion piece 32, and the ground wire 4, so that the static electricity on the conductor 2 can be removed. The grounding structure provided by the present invention only needs to insert the insertion piece 32 of the conductive sheet into the relief through-hole 11, and the clamping and fixing of the conductive sheet can be realized by means of the installation between the conductor 2 and the mounting body 1 to ensure that the elastic piece 33 and the conductor 2 are always in good contact. The ground wire 4 only needs to be wound around the insertion piece 32 or inserted into the insertion piece 32 through a plug spring to realize the electrical connection between the ground wire 4 and the conductor 2. At the same time, the insertion piece 32 extends to the side of the mounting body 1 facing away from the conductor 2, which is also convenient for the connection operation between the insertion piece 32 and the ground wire 4. Therefore, the grounding structure of the present invention not only has a simple structure, improves the assembly efficiency between the ground wire 4 and the conductor 2, but also has good grounding reliability.

[0045] There can be various specific installation methods of the conductive sheet on the installation body 1. In this embodiment, the installation body 1 is provided with an installation groove 12 adapted to accommodate the conductive sheet. This can determine the installation position of the conductive sheet on the installation body 1, facilitate the quick installation of the conductive sheet, and further improve the installation efficiency. As an alternative embodiment, the installation body 1 may not be provided with the installation groove 12.

[0046] The specific structural form of the main body 31 is not limited. In this embodiment, the main body 31 is a flat plate structure and its thickness is not greater than the depth of the installation groove 12. This can ensure that after the main body 31 is inserted into the installation groove 12, it will not protrude from the surface of the installation body 1, thereby making the installation between the conductor 2 and the installation body 1 more stable. As an alternative embodiment, the thickness of the main body 31 may also be greater than the depth of the installation groove 12.

[0047] There can be various specific setting methods of the elastic sheet 33. In this embodiment, the elastic sheet 33 is provided on one side of the main body 31 and extends from the main body 31 towards the conductor 2. As an alternative embodiment, the elastic sheet 33 may also extend from the main body 31 in a direction away from the conductor 2, in which case the part in contact with the conductor 2 is the main body 31.

[0048] There can be various specific structural forms of the elastic sheet 33. In this embodiment, the elastic sheet 33 includes an extension part 331 and a contact part 332.

[0049] The extension part 331 extends from one side of the main body 31 in a direction away from the main body 31 and inclines towards the conductor 2 during the extension process.

[0050] The contact part 332 extends from the end of the extension part 331 away from the main body 31 in a direction away from the main body 31 and is parallel to the main body 31.

[0051] The setting of the extension part 331 can endow the elastic sheet 33 with sufficient elasticity, so that the elastic sheet 33 can fit more closely with the conductor 2 and maintain good contact; the setting of the contact part 332 can ensure that there is sufficient contact area between the elastic sheet 33 and the conductor 2, thus achieving a better contact effect. By setting the extension part 331 and the contact part 332, the contact between the elastic sheet 33 and the conductor 2 can be both tight and sufficient, effectively improving the reliability of grounding.

[0052] As an alternative embodiment, the elastic sheet 33 may also only include the extension part 331. As another alternative embodiment, the contact part 332 may also be an arc-shaped structure.

[0053] The specific number of conductive sheets is not limited, which can enable the conductor 2 to make more sufficient contact with the conductive sheets and at the same time make the installation of the conductive sheets more stable. In this embodiment, the conductive sheet includes two elastic sheets 33, which are respectively located on both sides of the main body 31. As an alternative embodiment, the conductive sheet may also include only one elastic sheet 33, which is located on one side of the main body 31. As an alternative embodiment, the conductive sheet may also include three or more elastic sheets 33, which are dispersedly arranged on both sides or one side of the main body 31.

[0054] The insertion piece 32 of this embodiment is also provided with a connection through hole 321. As an alternative embodiment, the insertion piece 32 may not be provided with a connection through hole 321.

[0055] In order to further achieve the quick positioning of the conductive sheet on the installation body 1, the grounding structure provided in this embodiment further includes a positioning structure adapted to position between the conductive sheet and the installation body 1. As an alternative embodiment, the grounding structure may not include a positioning structure.

[0056] The specific structural form of the positioning structure is not limited. The positioning structure includes a positioning groove 51 and a positioning block 52.

[0057] The positioning groove 51 is provided on the conductive sheet.

[0058] The positioning block 52 is provided on the installation body 1 and is adapted to be inserted into the positioning groove 51 or the positioning hole.

[0059] In this way, only by inserting the positioning block 52 into the positioning groove 51 or the positioning hole, the quick positioning of the conductive sheet on the installation body 1 can be achieved, thereby further improving the assembly efficiency of the grounding structure.

[0060] As an alternative embodiment, it may also be that the positioning groove 51 is provided on the installation body 1 and the positioning block 52 is provided on the conductive sheet.

[0061] As an alternative embodiment, the positioning groove 51 may also be replaced by a positioning hole.

[0062] This embodiment also provides an air purifier, which includes a machine body 6 and the above-mentioned grounding structure. The installation body 1 is detachably installed on the machine body 6, and the machine body 6 is provided with an opening 61 adapted to allow the insertion piece 32 to extend out. Among them, the conductor 2 is a static electricity-carrying conductor 2 located around the electric purification module in the air purifier. Through the above-mentioned grounding device, the static electricity on the conductor 2 can be eliminated. The specific forms of the conductor 2 and the installation body 1 are not limited. In this embodiment, the conductor 2 is a guide rail in the air purifier, and the installation body 1 is a guide rail mounting bracket.

[0063] As an alternative embodiment, a part of the structure of the machine body 6 may also directly serve as the installation body 1.

[0064] As a transformable embodiment, the air purifier can also be replaced with other devices having a grounding structure.

For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description.
