DETAILED DESCRIPTION

[0028] The utility model Figures 1 to 9 As shown, an electric cleaning brush with adjustable brush head angle comprises a handle 10, a brush head body 20 rotatably mounted at the lower end of the handle 10, and an angle adjustment mechanism 30 connected between the lower end of the handle 10 and the brush head body 20, wherein:

[0029] The angle adjustment mechanism 30 includes a fan-shaped tooth plate 31, a reset member 32, a pressing member 33 and a positioning member 34. The fan-shaped tooth plate 31 is connected to the upper end of the brush head body 20, and has a plurality of tooth grooves 311 distributed at intervals; the pressing member 33 can be installed on the handle 10 by pressing up and down, and the pressing member 33 has a first inclined surface 331; the positioning member 34 can be elastically and telescopically installed at the lower end of the handle 10; the reset member 32 is installed between the positioning member 34 and the handle 10, and the positioning member 34 is embedded in the tooth groove 311 under the elastic drive of the reset member 32; and a second inclined surface 341 is provided on the positioning member 34 corresponding to the pressing member 33. As the pressing member 33 is pressed downward, the positioning member 34 moves backward to disengage from the tooth groove 311 under the cooperation of the first inclined surface 331 and the second inclined surface 341.

[0030] The pressing member 33 includes a pressing column 332, a limiting plate 333 and two driving plates 334. The limiting plate 333 is horizontally arranged at the lower end of the pressing column 332. The two driving plates 334 are symmetrically vertically connected to the lower end of the limiting plate 333. The first inclined surface 331 is formed at the lower end of one side of the two driving plates 334, and the first vertical contact plane 335 is formed at the other side of the two limiting plates 333. A reinforcing rib 333 is provided on the inner side of the driving plate 334. 41, so as to improve the structural strength of the pressing member 33 and improve its durability; a receiving hole 11 is provided at the lower end of the handle 10 corresponding to the pressing member 33, and the pressing member 33 can be floated in the receiving hole 11, and two limiting plates 333 are located on the inner side of the receiving hole 11, and can be detachably contacted with the edge of the receiving hole 11 as the pressing column 332 floats; when the pressing column 332 floats upward, the limiting plates 333 block the inner side of the edge of the receiving hole 11 to prevent the pressing member 33 from detaching from the receiving hole 11.

[0031] The positioning member 34 includes a base 342, an insert 343 arranged at the front end of the base 342 and a connecting column 344 arranged at the rear end of the base 342; wedge-shaped grooves 345 are symmetrically formed on both sides of the base 342, one side wall of the wedge-shaped groove 345 forms the second inclined surface 341, and the other side wall of the wedge-shaped groove 345 forms a second vertical contact plane 346, and the second vertical contact plane 346 matches the first vertical contact plane 335. When the driving plate 334 of the pressing member 33 is pressed to the limit position, the first vertical contact plane 335 and the second vertical contact plane 346 abut against each other, forming a horizontal sliding limit for the positioning member 34 and the vertical sliding limit for the pressing member 33. The handle 10 is provided with a slide groove 12 corresponding to the positioning member 34. The slide groove 12 and the lower end of the accommodating hole 11 are connected to each other up and down through a notch 121 opened on the side wall of the slide groove 12. The driving plate 334 of the pressing member 33 extends into the slide groove 12 through the notch 121 to drive the positioning member 34 to slide. A protruding hole 122 for the insert 343 to extend is provided at the front end of the slide groove 12. As the positioning member 34 slides, the insert 343 passes through the protruding hole 122 and extends into the tooth groove 311 to form an angle positioning. In this embodiment, the front end of the base 342 has two inserts 343, and the two inserts 343 are arranged laterally spaced from each other. In addition, a plurality of supporting ribs 123 for supporting the positioning member 34 and assisting its sliding are provided at the bottom of the slide groove 12 to improve the sliding stability of the positioning member 34 and the overall structural strength of the angle adjustment mechanism 30.

[0032] The reset member 32 is a spring, and a receiving groove 3421 for accommodating the end of the spring is formed at the rear end of the base 342. The connecting column 344 is arranged in the receiving groove 3421, and the end of the spring is inserted on the connecting column 344 and located in the receiving groove 3421; the spring is pressed between the receiving groove 3421 and the inner wall of the handle 10 to provide an elastic driving force for the forward extension of the positioning member 34, and also provides an elastic driving force for the upward floating reset of the pressing member 33.

[0033] The fan-shaped tooth plate 31 includes a middle plate 312 and a plurality of tooth grooves 311 symmetrically arranged on both sides of the middle plate 312; the tooth grooves 311 on both sides of the middle plate 312 correspond to the two inserts 343 at the front end of the base 342, and the two inserts 343 are correspondingly embedded in the tooth grooves 311 on both sides, and the gap between the middle plate 312 and the two inserts 343 is matched. Under the cooperation and limiting action of the two inserts 343, the two tooth grooves 311 and the middle plate 312, the positioning member 34 and the brush head body 20 form a stable combination state with a certain gap to prevent the brush head body 20 from shaking relative to the handle 10, thereby improving the overall structural stability of the product. The fan-shaped tooth plate 31 has three groups of tooth grooves 311, which are fan-shaped at angles of 0°, 45° and 90°. When adjusting the angle of the brush head body 20, the angles can be adjusted corresponding to 0°, 45° and 90°, which is convenient to use. It should be noted that in addition to the above-mentioned angles, more tooth grooves 311 can be added to meet the adjustment of more angles. In addition, a stress release groove 314 is provided between the adjacent tooth grooves 311 for releasing stress when the tooth grooves 311 are subjected to force, and the width of the stress release groove 314 is smaller than the width of the tooth groove 311. During the cleaning operation of the cleaning brush, the brush head body 20 is subjected to greater force, and the tooth groove 311 will be subjected to the extrusion stress from the handle 10. The stress release groove 314 can provide deformation space for the tooth groove 311, so that the stress on the side wall of the tooth groove 311 can be released through deformation in time, thereby avoiding the side wall of the tooth groove 311 from being broken due to force; indirectly, the stress on the insert 343 can also be released through the deformation of the tooth groove 311, thereby avoiding its damage due to force and extending the service life of the product.

[0034] The upper end of the brush head body 20 is recessed to form an arc-shaped rotation space 21 that rotates with the lower end of the handle 10. The fan-shaped tooth plate 31 is integrally arranged in the middle of the rotation space 21, and a pivot shaft 313 is transversely arranged on the fan-shaped tooth plate 31; the lower end of the handle 10 has two rotating parts 14 that match the rotation spaces 21 on both sides of the fan-shaped tooth plate 31, and a movable groove 15 that matches the fan-shaped tooth plate 31 is formed between the two rotating parts 14. The lower ends of the two rotating parts 14 are arc-shaped and correspond to the two rotation spaces 21. The fan-shaped tooth plate 31 extends into the movable groove 15. The fan-shaped tooth plate 31 is sandwiched between the two rotating parts 14 to prevent them from shaking, effectively improving the stability of the connection between the brush head body 20 and the handle 10.

[0035] The lower edge of the handle 10 is arc-shaped, and a pivot hole 13 is provided corresponding to the pivot shaft 313 at the lower end of the handle 10, and the pivot shaft 313 is inserted into the pivot hole 13. The lower end of the handle 10 matches the rotation space 21, and the arc-shaped rotation space 21 can meet the flexible adjustment of the brush head body 20 relative to the handle 10 within different angle ranges.

[0036] The angle adjustment method and principle of the electric cleaning brush are as follows: when adjusting the angle of the brush head body 20, press the pressing piece 33 downward, the first inclined surface 331 of the pressing piece 33 and the second inclined surface 341 of the driving piece slide in cooperation, the positioning piece 34 overcomes the elastic force of the spring and slides backward, and the embedded block 343 at the front end of the positioning piece 34 disengages from the tooth groove 311; at this time, the brush head body 20 can be rotated, and after adjusting to a suitable angle (45° or 90°), release the pressing piece 33, the spring drives the positioning piece 34 to slide forward, and the embedded block 343 is embedded in the tooth groove 311 again, and the angle of the brush head body 20 is fixed and completely locked; at the same time, with the cooperation of the first inclined surface 331 and the second inclined surface 341, the pressing piece 33 is reset upward; the angle of the brush head body 20 is adjusted.

[0037] The design focus of the utility model is that an angle adjustment mechanism is connected between the handle and the brush head body, and the angle adjustment mechanism uses the cooperation of the tooth groove and the insert block and the inclined driving principle to achieve the adjustment of the brush head body relative to the handle at multiple angles. Therefore, by adjusting the brush head body of the cleaning brush to turn 45° or 90°, the problem of some sanitary dead corners or high corners that cannot be cleaned during cleaning can be well solved, avoiding bending over or climbing up high to operate when cleaning sanitary dead corners, saving time and effort, and improving the convenience of cleaning.

[0038] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
