In addition, the terms "first", "second" are only for description purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first", "second" can be explicitly or implicitly included one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly specified and limited.

[0023] In the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting", "fixing" and the like should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0024] In combination with the accompanying drawings Figure 1 As shown in the drawings, an adjustable inlet and outlet size and distance dust collector nozzle assembly, including main shell 1, spring 2, middle layer flat suction port 3 and brush suction port 4, from the drawings, the main shell 1 is fixedly connected with the handle, the main shell 1 is a hollow shell, four pivot holes 1-2 are provided on the main shell 1, the pivot holes 1-2 are symmetrically distributed along the longitudinal axis of the main shell 1, and a groove is provided on the main shell 1 at the position of the pivot hole 1-2, the groove is provided to facilitate the smooth entry or exit of one end of the rotating part 5 into or out of the main shell 1, the groove cooperates with the outer wall of the rotating part 5, on the one hand, it does not hinder the rotating position of the rotating part, on the other hand, it needs to cooperate with the outer surface of the rotating part to form a relatively air-tight airflow channel. A pivot shaft 5-1 is provided on the rotating part 5, which can cooperate with the pivot hole 1-2 so that the main shell 1 and the rotating part 5 can rotate relative to each other, as shown in the drawings, the rotating part 5 is in the shape of a U-shaped structure, in combination with Figure 5It can be seen that the rotating part 5 also has a second elastic element mounting hole 5-2. The second elastic element mounting hole 5-2 is used to fix one end of the elastic element 2, and the other end of the elastic element 2 is installed in the first elastic element mounting hole 1-1. The first elastic element mounting hole 1-1 is located inside the main housing 1, specifically on a protrusion inside the main housing 1. In this invention, the elastic element 2 is selected as a spring. There are two springs, which are symmetrically distributed along the longitudinal axis of the main housing 1. Two first elastic element mounting holes 1-1 are also opened inside the main housing 1. (See attached diagram) Figure 7 A limiting part 5-3 is provided on one side of the rotating part 5. The limiting part 5-3 plays a role in positioning and guiding the rotating part 5 into the main housing 1. The position of the limiting part 5-3 is close to the position of the second spring mounting hole 5-2. In the second state, the limiting part 5-3 abuts against the main housing 1, thereby restricting the rotating part 5 from rotating out of position.

[0025] from Figure 1 It can also be seen that the middle layer flat suction port 3 is provided with a push knob 3-1 and a limiting hole 3-2. The push knob 3-1 is used to push the middle layer flat suction port 3 to slide relative to the main body shell 1. The limiting hole 3-2 is used to limit the relative displacement between the middle layer flat suction port 3 and the bristle brush suction port 4. It should be noted that the main body shell 1 is also provided with several limiting holes to limit the relative sliding between the main body shell 1 and the middle layer flat suction port 3 and prevent the two from sliding together when not in operation. The hook can be inserted into the limiting hole to limit the displacement between the two.

[0026] Combined with appendix Figures 1-6 As shown in the figure, a middle-layer flat suction port 3 is provided outside the main body shell 1, and a bristle brush suction port 4 is provided outside the middle-layer flat suction port 3. It can be seen from the figure that under the action of external force, the middle-layer flat suction port 3 can drive the bristle brush suction port 4 to slide relative to the main body shell 1, so that the vacuum cleaner enters the second working state. At the same time, under the action of external force, the bristle brush suction port 4 can slide relative to the middle-layer flat suction port 3, so that the vacuum cleaner enters the third working state.

[0027] Combined with appendix Figures 7-8 As shown, there are two implementations of the rotating component. The rotating component 5 includes a pivot shaft 5-1, a second elastic element mounting hole 5-2, and a limiting part 5-3. The limiting part 5-3 is located in different positions. Figure 7 The middle limiting part 5-3 can abut against the main housing 1, thereby restricting the rotation of the rotating part 5 from over-rotating.

[0028] Combined with appendix Figure 2 and 3As shown in the figure, in the initial state, the length of the dust collector is the shortest, the rotating part 5 and the main shell 1 form a T-shaped structure, so that the dust and impurities can enter the dust collector, in the initial state, the spring is in tension, the purpose of setting the spring is to facilitate the later homing of the rotating part, under the action of the elastic restoring force of the spring, the rotating part 5 can automatically open and keep the open position, thereby improving the experience and completing the actual function.

[0029] In combination with the accompanying drawings Figure 4 And 5 As shown in the figure, in the second working state of the inlet and outlet distance adjustable dust collector, the middle layer flat suction port 3 slides relative to the main shell 1, the middle layer flat suction port 3 pushes one end of the rotating part 5 to rotate inside the main shell 1, under the action of the elastic restoring force of the spring, one end of the rotating part 5 rotates into the main shell 1, and the other end protrudes from the main shell 1 and is slightly flush with the front end of the middle layer flat suction port 3.

[0030] In combination with the accompanying drawings Figure 6 As shown in the figure, in the third working state of the inlet and outlet distance adjustable dust collector, the length of the dust collector is the longest, in the third working state, the brush suction port 4 works, and the longitudinal brush is arranged on the outer wall of the brush suction port 4 to clean the dust.

[0031] Working state: In the initial state, the rotating part 5 protrudes from the main shell 1, and the rotating part 5 and the main shell 1 form a T-shaped structure. In the initial state, the length of the gas passage is the shortest, but in this state, the gas inlet opening is the largest, and the gas inlet is in a T-shaped structure.

[0032] In the second state, the middle layer flat suction port 3 slides to the front end of the main shell 1, the length of the airflow passage increases, the rotating part 5 rotates into the main shell 1, and the middle layer flat suction port 3 slides to the rear end of the main shell 2, from the second state to the initial state.

[0033] In the third state, the brush suction port 4 slides to the front end of the middle layer flat suction port 3, and in this state, the length of the airflow passage is the longest.

[0034] In the description of the present specification, the description of the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention.
