[0041] In order to make the purpose, technical content and advantages of the present application more clear, the following will be further described in detail with specific embodiments and with reference to the drawings.

[0042] In order to make the purpose, technical content and advantages of the present application more clear, the following will be further described in detail with specific embodiments and with reference to the drawings.

[0043] First, as shown in Figure 1 , Figure 2 , Figure 3 , an adjusting knob assembly of a paint spraying gun, comprising an adjusting seat 10 and a knob 20, the adjusting seat 10 is arranged at a first adjustment site 31 of a paint spraying gun 30 for adjusting flow, the first adjustment site 31 is provided with an indicating arrow 32 on the surface thereof, the adjusting seat 10 is axially provided with an adjusting screw hole 11, and a plurality of stage grooves 12 are equidistantly arranged on the outer surface of the adjusting seat 10, the stage grooves 12 are adjacent to the indicating arrow 32 of the first adjustment site 31, the knob 20 is a conical column and is axially equidistantly provided with a plurality of grooves 21 on the outer surface thereof, and a plurality of adjustment scales 22 are sequentially arranged on the outer surface of the knob 20 along the radial direction between the grooves 21, the knob 20 is internally provided with a center stud 23, and an annular groove chamber 24 is formed on the outer periphery of the center stud 23, the center stud 23 is screwed into the adjusting screw hole 11 of the adjusting seat 10, further the knob 20 is annularly arranged on the outer surface of the adjusting seat 10, and the flow size is adjusted by rotating the knob 20, and the adjustment scales 22 correspond to the indicating arrow 32 for facilitating the viewing and adjustment of the flow, and the displacement generated by the rotation of the knob 20 sequentially moves along the stage grooves 12, further the number of rotation turns of the knob 20 is obtained, and accordingly the value of the flow after adjustment can be clearly and obviously obtained from the knob.

[0044] Secondly, as shown in Figure 4 , the outer surface of the adjusting seat 10 is further provided with a surface treatment layer 13.

[0045] Further, the paint spraying gun 30 has flow adjustment sites for adjusting paint amount, air input amount and air output amount according to functions, please simultaneously refer to Figure 1And Figure 3 As shown in the drawings, the first adjustment site 31 is used for paint volume adjustment, the second adjustment site 31' is used for air input volume adjustment, and the third adjustment site 31" is used for air output adjustment. The first adjustment site 31, the second adjustment site 31', and the third adjustment site 31" are all provided with the adjustment seat 10 and the knob 20 rotatingly adjusted along the adjustment seat 10.

[0046] The paint volume adjustment component embodiment is shown in the drawings Figure 2 The paint gun 30 is internally provided with a needle valve 33 and a spring 34 connected to the needle valve 33. The ends of the needle valve 33 and the spring 34 are pierced by the adjustment screw hole 11 of the adjustment seat 10. The central stud 23 of the knob 20 is provided with an axial hole 231, which accommodates the ends of the spring 34 and the needle valve 33. The displacement amount generated by the rotation of the knob 20 is used to adjust the needle valve 33, thereby achieving the purpose of adjusting the paint volume.

[0047] The actual adjustment state of the component is shown in the drawings Figure 5 And Figure 6 When the paint gun 30 is adjusted for flow rate, the knob 20 is rotated to achieve the adjustment purpose. When the knob 20 is not yet rotated and is in the flow rate zero state, the adjustment scale 22 of the knob 20 is opposite the indicator arrow 32 with the number 0, and the end edge of the knob 20 is aligned with the first stage groove 12. When the knob 20 is rotated to adjust the flow rate, the drawings show that Figure 7 And Figure 8 First, the number of the adjustment scale 22 is used to adjust the required flow rate. Since the knob 20 rotates along the outer diameter of the adjustment seat 10, the stage grooves 12 gradually appear or are hidden due to the rotation displacement of the knob 20. The displacement amount of the knob 20 rotating one circle along the adjustment screw hole 11 of the adjustment seat 10 with the central stud 23 is equal to the distance between two stage grooves 12. Therefore, when the knob 20 is rotated half a circle, the knob 20 is between two stage grooves 12. Second, when the knob 20 is rotated one circle and the adjustment scale 22 returns to the number 0 opposite the indicator arrow 32, the first stage groove 12 of the adjustment seat 10 is completely exposed, and the end edge of the knob 20 is aligned with the second stage groove 12, indicating that the flow rate value has exceeded the maximum number after one rotation of the knob 20 (the maximum number of the adjustment scale 22 in this embodiment is 9), and the flow rate value is gradually increased by carry-over. In this way, when the knob 20 is rotated two circles, the drawings show that Figure 9 And Figure 10As shown, the two stage grooves 12 of the adjustment seat 10 are exposed, and the end edge of the knob 20 is aligned with the third stage groove 12; accordingly, the value indicated by the adjustment scale 22 of the knob 20 relative to the indicating arrow 32, and the position of the stage groove 12 corresponding to the rotational displacement of the knob 20, can not only greatly simplify the adjustment assembly of the flow adjustment, but also enable the user to clearly know the current flow adjustment state when adjusting the flow size of the first adjustment position 31, the second adjustment position 31', and the third adjustment position 31" of the paint spraying gun 30, thereby helping to improve the convenience and accuracy of the flow adjustment, and thus improving the selection and purchase willingness of the consumer.

[0048] The above-mentioned is only an optional embodiment of the present application, and cannot limit the scope of the embodiments of the present application; that is, any equivalent changes and modifications made in accordance with the claims of the present application should still be included in the scope of the present application.

[0049] The above-mentioned specific embodiments further specifically describe the purpose, technical solutions, and beneficial effects of the present application, and it should be understood that the above-mentioned is only a specific embodiment of the present application, and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
