[0035] Reference Figure 1 And 2 The present application discloses a cleaning head 1, which is detachably mounted on a dust collector 100. The dust collector 100 can be a stand-type dust collector 100, a handheld dust collector 100 or a horizontal dust collector 100. The cleaning head 1 is defined as a fluid passage 11 in fluid communication with the dust collector 100. The suction airflow generated by the dust collector 100 can suck dirt through the fluid passage 11 into the dust storage container (dust cup or dust bag, etc.) of the dust collector 100. Referring to Figures 2-6 The cleaning head 1 includes a connecting bracket 12, a connecting head 13 and a first suction nozzle 14. The connecting bracket 12 includes a first end portion 121 and a second end portion 122 arranged oppositely, and the first end portion 121 is detachably connected to the connecting pipe 101 of the handheld dust collector 100. The connecting head 13 is rotatably arranged on the second end portion 122 (referring to Figure 3 And Figure 4The first suction nozzle 14 is connected to the connector 13. The first suction nozzle 14 can rotate with the connector 13 relative to the second end 122 of the connecting bracket 12. The end of the first suction nozzle 14 away from the second end 122 is provided with a first suction port 141. The first suction nozzle 14 includes a first fluid channel 101, and the connecting bracket 12 includes a second fluid channel 102. The first fluid channel 101 and the second fluid channel 102 communicate to form a complete fluid channel 11. A second suction nozzle 15 is movably disposed on the first suction nozzle 14. The second suction nozzle 15 defines a second suction port 151, wherein the second suction port 151 includes a first position and a second position. In the first position (refer to...), Figure 2 The second suction port 151 is disconnected from the fluid channel 11. In the second position (refer to...) Figure 3 The second suction port 151 is connected to the fluid channel 11. The second suction nozzle 15 is slidably disposed on the first suction nozzle 14. The second suction nozzle 15 is sleeved on the outer periphery of the first suction nozzle 14, and the second suction nozzle 15 can slide along the length direction of the first suction nozzle 14. When the second suction nozzle 15 is in the second position, the second suction nozzle 15 covers the first suction port 141. The user can use the second suction port 151 to clean the surface to be cleaned.

[0036] In other embodiments, the second suction nozzle 15 may also be rotatably mounted on the first suction nozzle 14. The second suction nozzle 15 can rotate relative to the first suction nozzle 14. When the second suction port 151 of the second suction nozzle 15 rotates to a position where it is in fluid communication with the fluid channel 11, the first suction port 141 can be closed, or it can be used in conjunction with the second suction port 151. The second suction nozzle 15 may also be provided with bristles or other cleaning attachments. The suction port area of ​​the second suction port 151 may be smaller than the suction port area of ​​the first suction port 141.

[0037] refer to Figure 5 and 6 One of the second end 122 and the connector 13 defines a mounting space, and at least a portion of the other of the second end 122 and the connector 13 is rotatably mounted within the mounting space. (See reference) Figure 6 and Figure 8 The connector 13 is provided with a first limiting structure 16, and the second end 122 is provided with a second limiting structure 17. The first limiting structure 16 and the second limiting structure 17 cooperate with each other to limit the relative position between the connector 13 and the second end 122. This makes it more convenient for users to use.

[0038] Specifically, as shown in the embodiment, the first limiting structure 16 includes an annular structure 161 and a limiting protrusion 162 disposed on the annular structure 161; the second limiting structure 17 includes a plurality of limiting grooves 171 corresponding to the limiting protrusion 162, and the limiting protrusion 162 can move between the plurality of limiting grooves 171. The limiting protrusion 162 can move between different limiting grooves 171 to adjust its angle to meet different usage scenarios.

[0039] like Figures 5-10 In the embodiment shown, the second end 122 includes a first support 123 and a second support 124, which together define an installation space for accommodating at least a portion of the connector 13. The first support 123 and the second support 124 are each hemispherical in shape. When the two are engaged together, they form an installation space for mounting the connector 13.

[0040] refer to Figures 5-10 The connector 13 includes a third connector 131 and a fourth connector 132, which define a receiving space when installed together. Similarly, the third connector 131 and the fourth connector 132 can also be hemispherical in shape. When they are engaged, they can move relative to the second end 122 within the installation space, allowing the first suction nozzle 14 to rotate relative to the connecting bracket 12 and change its angle to adapt to more cleaning scenarios.

[0041] During installation, the third connector 131 and the fourth connector 132 can be installed onto the first nozzle 14 first, and then the first support 123 and the second support 124 can be installed onto the outer periphery of the connector 13 to fix the first support 123 and the second support 124 together.

[0042] Referring to the diagram, to facilitate clearer viewing of dirt on the surface to be cleaned when cleaning narrow crevices, the cleaning head 1 is equipped with a light-emitting device 18, which is located inside the connector 13. To guide the light to the first suction port 141, a light guide post 19 is provided on the first suction nozzle 14. The light guide post 19 is used to guide the light generated by the light-emitting device 18 to the first suction port 141.

[0043] refer to Figures 11-12 As shown in the embodiment, the first suction nozzle 14 is constructed in a flat shape and defines a first fluid channel 101. The light guide post 19 is disposed on the outside of the first fluid channel 101. The light guide post 19 extends along the length direction of the first suction nozzle 14 and can effectively guide the light generated by the light-emitting device 18 to the vicinity of the first suction port 141, so that the user can clearly see the dirt on the surface to be cleaned.
