[0001] This utility model relates to the field of negative ion technology, and in particular to a carbon brush holder for modular assembly. Background Technology

[0002] With social development, consumers are becoming more and more accepting of negative ion products. However, the development and design of such products requires independent design of the negative ion carbon brush mounting structure according to different product categories, which not only greatly increases the product development cycle, but also increases the product design cost. Utility Model Content

[0003] The present invention aims to solve the above-mentioned technical problems and provide a modular assembly carbon brush holder, which realizes modular assembly of negative ion carbon brushes, greatly reduces the assembly difficulty of negative ion carbon brushes, improves product development and design efficiency, and reduces the installation cost of negative ion carbon brushes in products.

[0004] To solve the above-mentioned technical problems, the present invention provides a modular carbon brush holder, which includes a holder body. The holder body is an integral modular structure.

[0008] Furthermore, the ear seat back plate is provided with grooves distributed along its height, and the cylindrical part is provided with a ridge that is embedded in the grooves.

[0009] Furthermore, the backplate is provided with a columnar part installed at the drain hole.

[0010] Furthermore, the cylindrical portion is planar on the side away from the backplate, and the planar sidewall has a suspended lower extension.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] This utility model provides a modular assembly carbon brush holder, see [link to relevant documentation]. Figure 1-5 As shown, the modular carbon brush holder includes a holder body, which is an integral modular structure. The holder body has an ear base 1 and a back support 2. The ear base 1 can be fixed in a negative ion generator or negative ion air purifier (corresponding to the preset position for installing the carbon brush). The ear base 1 of the integral modular structure has an ear base plate 10, which is generally square. The ear base plate with a certain thickness needs a certain structural strength to meet its own load-bearing requirements. The ear base plate is provided with a set of holes 14, which includes two round holes. An ear base back plate 11 is arranged at one end of the ear base plate 10. The width of the ear base back plate can be the same as or slightly larger than the width of the ear base plate. Hollow cylindrical parts 12 are symmetrically arranged at both ends of the ear base back plate. The hollow cylindrical parts can be adapted to the installation requirements of the carbon brush. The back support plate 20 of the back support 2 is arranged on the surface of the ear base plate. After the back support plate 20 and the surface of the ear base plate are attached to each other, they have a large contact surface to ensure the stability of the force between them. The backing plate has a U-shaped top section 21, and the two free ends of the top section have a beveled structure. The top section has a cylindrical section 22 with an open end, which can be used to install the cleaning mechanism drive motor. The bottom of the cylindrical section has a central hole 23, which allows the power end of the cleaning mechanism drive motor to extend out.

[0025] It should be noted that the hollow cylindrical section has a main hole portion 12a with an inner diameter of R1 and an end hole portion 12b with an inner diameter of R2, where R1 is larger than R2. These two different inner diameters facilitate the assembly of the negative ion carbon brush at different positions. A variable diameter channel 12c connects the main hole portion and the end hole portion. This variable diameter portion not only ensures communication between the upper and lower channels but also simultaneously constrains the longitudinal movement of the carbon brush within the channel, effectively preventing it from dislodging from the channel. The main hole portion accounts for 90%-95% of the height of the hollow cylindrical section. This long stroke of the main hole portion is beneficial for the layout of conductor components such as wire harnesses. The end hole portion accounts for 3%-4% of the height of the hollow cylindrical section, and the carbon brush extends from the end hole portion throughout the entire hollow cylindrical section.

[0026] See Figure 3-5The ear seat plate 11 is provided with a groove 13 distributed along its height. The groove can be a trapezoidal structure in cross section. The cylindrical part is provided with a back ridge 24 embedded in the groove. The back ridge is integrally formed with the cylindrical part and its shape is adapted to the groove. The above structure can constrain the lateral displacement of the cylindrical part and can better realize the positioning and installation requirements between them.

[0027] See Figure 5 The back support plate 20 is provided with a columnar part 25 installed at the row hole. The columnar part 25 can be located at one of the row holes to realize the mutual constraint and positioning requirements of the two structural components. The opening provided on the back support plate 20 adjacent to the columnar part can cooperate with another row hole to realize the fixing requirements of the entire modular assembly carbon brush bracket on the relevant product. The fixing methods include, but are not limited to, bolts and screws.

[0028] See Figure 5 The cylindrical part is planar on the side away from the back plate 20. The planar sidewall has a suspended lower extension 26. The cross-section of the extension can be trapezoidal. The extension can serve as a stroke constraint device for the carbon brush cleaning mechanism. When the motor drives the cleaning structure to rotate and touches the lower extension, the limit motion is reached and the rotation is reset.

[0029] Figure 6 The image shows the effect of carbon brush P and carbon brush cleaning structure M installed on a modular assembly carbon brush holder.

[0030] The second embodiment of this utility model provides a modularly assembled carbon brush holder, which differs from the first embodiment in that it has two sets of perforations. See [link to embodiment]. Figure 7 In this embodiment, the holes are arranged in two groups side by side, totaling four round holes. This design allows for flexible adjustment of the installation position of the carbon brush cleaning structure M according to on-site installation needs.

[0031] The third embodiment of this utility model provides a modular assembly carbon brush holder, which differs from the second embodiment in that, see [link to second embodiment]. Figure 8 The spacing between the two sets of holes is larger.

[0032] The fourth embodiment of this utility model provides a modular assembly carbon brush holder, which includes a holder body, see [link to previous embodiment]. Figure 9The bracket body is an integral modular structure. The ear base 1 of the integral modular structure has an ear base plate 10. The ear base plate is provided with three sets of holes 14. An ear base back plate 11 is arranged at one end of the ear base plate 10. Hollow cylindrical tubes 12 are symmetrically arranged at both ends of the ear base back plate. The ear base back plate is also provided with a middle hollow cylindrical tube. Two or more middle hollow cylindrical tubes 15 can be added as needed. Then, a matching back support 2 is provided to carry their respective carbon brush cleaning mechanisms. The back support plate 20 of the back support 2 is arranged on the surface of the ear base plate. The edge of the back support plate is provided with a U-shaped top circumference 21. The top circumference is provided with a cylindrical tube 22 with an open end. The bottom of the cylindrical tube is provided with a central hole 23.

[0033] Products that can use this utility model include negative ion generators, negative ion air purifiers, etc.

[0034] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
