[0027] Example: Figure 1-12 As shown, the present invention discloses a specific embodiment of a vacuum cleaner accessory, which includes a first housing 100, a first body 120 fixedly connected to and at least partially covered by the first housing 100 and having a main suction port 122, a second housing 200 that can be snapped to the first housing 100, a second body 220 fixedly connected to and at least partially covered by the second housing 200 and having a side suction port 204, a rotary joint 300 fixed to the first housing 100 and rotatable relative to it in a first direction, and a bent pipe joint 320 disposed on the rotary joint 300 and rotatable relative to it in a second direction, wherein the first body 100 is telescopically movable relative to the second body 220.

[0028] Both the first housing 100 and the second housing 200 are rectangular. The first housing 100 includes a central hole 132 through which the rotary joint 300 passes and a locking groove 140 disposed on one side of the central hole 132. The second housing 200 includes a locking element 240 that is fixed in place with the locking groove 140. The first housing 100 is telescopically movable relative to the second housing 200. The length of either the first housing 100 or the second housing 200 is greater than its width. The second housing 200 has a housing cavity 202.

[0029] The first body 120 includes a pair of main suction ports 122, four sliding grooves 124, a pair of sliding cavities 126 that accommodate two corresponding sliding grooves 124, a base 127 located between the two sliding cavities 126, a side wall 128 disposed opposite to the base 127, a first inner cavity 130 surrounded by the side wall 128 and communicating with both the central hole 132 and the main suction ports 122, and a side air inlet 134 connected at one end to the first inner cavity 130 and at the other end to the side suction port 204. The second body 220 includes a pair of air inlet grooves 221 that allow dust-laden airflow to enter, a pair of main air inlets 222 located on one side of the air inlet grooves 221 and communicating with the corresponding main suction ports 122, four fixed posts 224 that can slide in the corresponding sliding grooves 124, a second inner cavity 226 surrounded by the fixed posts 224 and capable of accommodating the base 127, and a plurality of fixed holes 229 located on one side. The distance between the side suction port 204 and the center of the first inner cavity 130 is greater than the distance between the main suction port 122 and the center of the first inner cavity 130. The length of the air intake groove 221 is greater than the length of the first inner cavity 130. An elastic element 160 is provided between the first body 120 and the second body 220 to ensure reciprocating movement. Each fixing post 224 has a screw-connected washer 228 at its top end to prevent the fixing post 224 from separating from the sliding groove 124 in the vertical direction. The sliding groove 124 is a closed groove and is isolated from the sliding cavity 126. The first body 120 is also provided with fixing holes 229. In this embodiment, there are two main suction ports 122 arranged in a front-to-back arrangement, and there are also two air intake grooves 221, with the main suction port 122 located between the two air intake grooves 221. Thus, the airflow enters the air intake groove 221 from the front-to-back direction and then converges into the first inner cavity 130 located in the middle.

[0030] The rotary joint 300 rotates 90 degrees relative to the first housing 100 about a vertical horizontal plane, and the elbow joint 320 can rotate relative to the rotary joint 300 in the back-and-forth direction. The rotary joint 300 is connected to the elbow joint 320 via a hose 340, thereby delivering dust-laden airflow to the vacuum cleaner main unit. Both the rotary joint 300 and the elbow joint 320 are hollow to accommodate the hose 340. The rotary joint 300 includes a connector inlet 302 passing through a central hole 132, while the elbow joint 320 includes a connector outlet 322 that mates with the vacuum cleaner main unit or a connecting pipe.

[0031] To ensure that the bend joint 320 can rotate relative to the rotary joint 300 in the front-rear direction, this embodiment further includes a snap-fit ​​shaft hole on the rotary joint 300, a plurality of snap-fit ​​protrusions 304 arranged annularly and spaced around the snap-fit ​​shaft hole on the rotary joint 300, a bend opening 324 on the bend joint 320 that allows the snap-fit ​​protrusions 304 to pass through, and a snap-fit ​​cover plate 310 having a shaft-like portion that can pass through the snap-fit ​​shaft hole. The snap-fit ​​protrusions 304 are located inside the bend opening 324, while the snap-fit ​​cover plate 310 is located outside the bend opening 324. The bend opening 324 is shaped like a quincunx. The snap-fit ​​cover plate 310 at least partially covers the bend opening 324. The shaft-like portion can rotate relative to the snap-fit ​​shaft hole.

[0032] This embodiment also includes a caster wheel assembly 400 disposed at the bottom of the first body 120 and the second body 220. The caster wheel assembly 400 includes a wheel body 410, a roller 430 that can be inserted through the wheel body 410, and a pair of rollers 420 fixed at both ends of the roller 430. The wheel body 410 includes a base 412 located between the two rollers 420, a rod-shaped portion 414 connected to the base 412, and a retaining ring 440 that fixes the rod-shaped portion 414 to the first body 120 or the second body 220. The rod-shaped portion 414 is inserted into the fixing hole 229 and is secured by the retaining ring 440 to prevent it from loosening in the vertical direction. The rollers 420 can rotate both around the center of the rod-shaped portion 414 and around the roller 430, thereby achieving 360-degree omnidirectional rotation.

[0033] When using it for the first time, such as Figure 5 , 8 As shown in Figures 9 and 11, the first housing 100 and the second housing 200 move forward along the front-to-back direction (perpendicular to their length). Most of the dust-laden airflow enters the main air inlet 222 from the air inlet slots 221 on both the front and rear sides. Since the main suction port 122 and the main air inlet 222 are connected, the airflow enters the first inner cavity 130 and then enters the hose 340 through the connector air inlet 302, and then enters the vacuum cleaner main unit or connecting pipe through the connector air outlet 322. At the same time, a small portion of the dust-laden airflow enters the housing cavity 202 from the side suction port 204, enters the first inner cavity 130 through the side air inlet 134, and also enters the hose 340 through the connector air inlet 302, and then enters the vacuum cleaner main unit or connecting pipe through the connector air outlet 322. When it is necessary to use it in narrow or corner environments, such as Figure 2 , 6As shown in Figures 8 and 12, the locking fastener 240 and the locking groove 140 are first manually unlocked, and then the rotary joint 300 is rotated 90 degrees relative to the first housing 100. The bent pipe joint 320 rotates relative to the rotary joint 300 in the front-back direction. The first housing 100 and the second housing 200 move forward in the left-right direction (length direction). Then the second body 220 is stretched relative to the first body 120, and the elastic element 160 is stretched. Since the main air inlet 222 is far away from the main suction port 122 and the two are not connected, most of the dust-laden airflow enters the housing cavity 202 from the side suction port 204, enters the first inner cavity 130 through the side air inlet 134, enters the hose 340 through the joint air inlet end 302, and then enters the vacuum cleaner main unit or connecting pipe through the joint air outlet end 322.

[0034] The advantages of this invention are: it is suitable for use in different scenarios, especially in narrow spaces and other dead angle environments, and it can ensure omnidirectional rotation at the bottom, allowing for flexible use at multiple angles.
