The adjusting assembly 103 is connected to the mounting surface 601, and the adjusting assembly 103 can adjust the inclination of the cleaning assembly 101 relative to the vertical direction.

[0030] The cleaning surface 102 in the prior art is not necessarily perpendicular to the probe 301, and when the cleaning surface 102 has a certain inclination, the back-and-forth movement of the probe 301 cannot clean all parts of the surface of the probe 301 well.

The adjusting plate 105 is fixedly connected to the cleaning assembly 101. The adjusting bolt 201 can be rotated to adjust the distance between the first bottom plate 104 and the adjusting plate 105. Figure 2In the shown structure, the adjusting plate 105 is provided with a threaded hole, and the screw rod 206 is threadedly connected to the adjusting plate 105, and the end of the screw rod 206 away from the head 205 abuts against the first bottom plate 104, so that rotating the adjusting bolt 201 can make the screw rod 206 rotate in the adjusting plate 105, so that the end of the screw rod 206 away from the head 205 abuts against the first bottom plate 104 to increase or decrease the distance between the first bottom plate 104 and the adjusting plate 105, by changing the local distance between the first bottom plate 104 and the adjusting plate 105 at the position of the adjusting bolt 201, the inclination of the adjusting plate 105 relative to the vertical direction is changed, so that the inclination of the cleaning assembly 101 mounted on the adjusting plate 105 is changed. The way of adjusting bolt 201 to change the inclination is intuitive and convenient, rotating the adjusting bolt 201 can increase or decrease the distance to adjust the inclination, the structure of the adjusting bolt 201 is simple and easy to process, the corresponding size threaded hole can be provided in any one of the two plates that need to be adjusted, and the adjusting bolt 201 can be installed, and different positions and different numbers can be set according to the needs.

The position of changing the inclination can also not be limited between the first bottom plate 104 and the adjusting plate 105, but an adjusting device can also be arranged between the mounting surface 601 and the adjusting plate 105, and finally the inclination of the cleaning surface 102 relative to the vertical direction can be changed. In some embodiments of the present application, threaded holes can also be provided on the first bottom plate 104, the adjusting bolt 201 is arranged on the first bottom plate 104, and abuts against the adjusting plate 105, and the same technical effect of adjusting the inclination can also be achieved.

[0032] Reference Figure 2 and Figure 5 In some embodiments of the present application, the adjusting plate 105 has two long edges 501 and two short edges 502, the two long edges 501 are spaced apart, the two ends of the long edge 501 are respectively connected to the two short edges 502, the two ends of the short edge 502 are respectively connected to the two long edges 501, the long edge 501 and the short edge 502 are perpendicular to each other, the adjusting bolt 201 is provided with eight, and one adjusting bolt 201 is arranged at the two ends of each long edge 501 and the two ends of each short edge 502. The rectangular shape with two long edges 501 and two short edges 502 can more intuitively see the inclination, when it is found that the cleaning surface 102 and the probe 301 do not keep vertical, the rectangular shape can see whether it is inclined to the left and right direction or the up and down direction, and eight adjusting bolts 201 are arranged and Figure 5The arrangement is to adjust better for the inclination, specifically, in some embodiments of the utility model, the adjusting plate 105 is parallel to the cleaning surface 102, when the cleaning surface 102 is inclined to the left, the two adjusting bolts 201 at the leftmost end are adjusted to increase the distance between the adjusting plate 105 at the position and the first bottom plate 104, if there is also inclination in the up-down direction, the adjusting bolt 201 at the up-down position is adjusted, the eight adjusting bolts 201 have greater adjustable space, can make the cleaning surface 102 as possible perpendicular to the probe 301. Figure 3 The eight adjusting bolts 201 and the arrangement position shown are one kind in the embodiments of the utility model, in some embodiments, the position and quantity of the adjusting bolt 201 can also be adjusted according to the accuracy requirement of inclination, the processing cost and the complexity of components, for example, when the accuracy requirement is low, one adjusting bolt 201 is also set at each corner of the adjusting plate 105. Figure 5 The eight adjusting bolts 201 and the arrangement position shown are one kind in the embodiments of the utility model, in some embodiments, the position and quantity of the adjusting bolt 201 can also be adjusted according to the accuracy requirement of inclination, the processing cost and the complexity of components, for example, when the accuracy requirement is low, one adjusting bolt 201 is also set at each corner of the adjusting plate 105.

[0033] Reference Figure 2 And Figure 5 In some embodiments of the utility model, the adjusting assembly 103 further includes four connecting pieces 503, the connecting piece 503 connects the first bottom plate 104 and the adjusting plate 105, any one connecting piece 503 is provided with one adjusting bolt 201 along the direction of interval distribution of the long side 501, any one connecting piece 503 is provided with one adjusting bolt 201 along the direction of interval distribution of the short side 502. The connecting piece 503 can make the first bottom plate 104 and the adjusting plate 105 not fall off when the adjusting bolt 201 is adjusted, improve the structural stability, specifically, in some embodiments of the utility model, the connecting piece 503 can use the connecting bolt, it needs to be explained that the adjustment of inclination is actually very small, because in the ideal case, the components will be set like Figure 3 And Figure 4The connection pieces 503 are perpendicular to the probe 301, so even if the connection pieces 503 are connected by bolts, the adjustment bolts 201 can still be fine-tuned. Four connection pieces 503 are provided and each of the connection pieces 503 is adjacent to one adjustment bolt 201 in the length and width directions, because the inclination between the adjustment plate 105 and the first bottom plate 104 is often caused by slight differences in the connection parts, for example, the position connected more tightly is relatively inclined downward, so that the adjustment bolt 201 and the connection piece 503 are adjacent to each other, which can better adjust the inclination of each position, and facilitate the adjustment of the inclination of the cleaning surface 102 relative to the vertical direction. It should be noted that the above-mentioned adjacent arrangement means that each connection piece 503 has the nearest adjustment bolt 201, and the nearest adjustment bolt 201 is located in the up-down direction or the left-right direction of the connection piece 503, and adjusting the adjustment bolt 201 at this position can directly affect the inclination of the adjustment plate 105 at the position of the connection piece 503.

Good elasticity ensures that the brush 107 can still maintain good cleaning effect after long-term use. In addition, PBT also has good wear resistance, heat resistance and chemical stability, and is easy to clean and does not breed bacteria. The cleaned PBT brush 107 can quickly restore its original cleaning ability to ensure that it still achieves good cleaning effect next time. It should be noted that, in some embodiments of the utility model, the brush 107 can also use nanometer stainless steel, nylon and the like.
