Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a dual-purpose dust collector that combines blowing and suction with multi-directional air intake or multi-directional air exhaust. Background Technology

[0002] Vacuum blowers and vacuum cleaners are two common household appliances, used for blowing and vacuuming respectively. To achieve multi-functional integration, there are also appliances that can both blow and vacuum. A Chinese patent with publication number CN118235928A discloses a dual-function blower / vacuum device. This appliance can perform both blowing and vacuuming functions separately. However, the air inlet and outlet of the blower / vacuum unit (air duct) are located at opposite ends of the air duct, and the air can only be emitted along the axial direction of the air duct. Due to user habits, users tend to point the air outlet directly at their face, resulting in a poor user experience for the dual-function blower / vacuum device. Utility Model Content

[0003] The present invention provides a dual-purpose dust collector that combines blowing and suction, with multi-directional air intake or multi-directional air outlet, to solve the technical problem that the air outlet or air inlet of the existing dual-purpose blowing and suction devices can only be directly facing the face, resulting in a poor user experience.

[0004] This utility model discloses a dual-purpose dust collector integrating blowing and suction with multi-directional air intake or multi-directional air outlet, comprising:

[0005] A ventilation duct has a first end and a second end arranged opposite to each other along its axial direction, and an airflow channel formed between the first end and the second end. The airflow channel forms a first air outlet at the first end, and forms a second air outlet and a third air outlet at the second end. The second air outlet is located on the axial end face of the second end away from the first end, and the third air outlet is located on the outer peripheral wall of the second end. A first dust removal pipe is installed at the first air outlet, and a second dust removal pipe is installed at the second air outlet.

[0006] A fan is provided in the air duct and is used to generate airflow in the airflow channel when started, so that the airflow flows from the first end to the second end, or from the second end to the first end;

[0007] A wind control component is disposed at the second end and located on the path of the airflow channel. The wind control component includes a first cover plate and a second cover plate. The first cover plate is provided with an air passage for airflow in the airflow channel to flow between the first end and the second end. The second cover plate is provided with a first channel and a second channel on the side facing the first cover plate. The second cover plate is rotatably connected to the first cover plate and can rotate relative to the first cover plate to switch between a first state and a second state. In the first state, the second air outlet is blocked, and the two ends of the first channel are respectively aligned and connected to the air passage and the third air outlet. The airflow in the airflow channel flows through the first air outlet, the air passage, the first channel, and the third air outlet. In the second state, the third air outlet is blocked, and the two ends of the second channel are respectively aligned and connected to the air passage and the second air outlet. The airflow in the airflow channel flows through the first air outlet, the air passage, the second channel, and the second air outlet.

[0008] In one embodiment, the number of air ducts, the first channel, and the second channel is multiple and the same, and the air ducts are spaced apart on the first cover plate along the circumference of the air duct; the first channel and the second channel are staggered on the second cover plate along the circumference of the air duct.

[0009] In one embodiment, the second cover plate has an airflow cavity on the side facing the first cover plate, and the first cover plate covers the opening side of the airflow cavity; the bottom wall of the airflow cavity has a first through hole, a portion of the outer side wall of the airflow cavity is recessed inward to form the first channel, a portion of the inner side wall of the airflow cavity is recessed outward to form the second channel, and the second channel communicates with the interior of the airflow cavity.

[0010] In one embodiment, the first cover plate has a plurality of protruding locking blocks on the side facing the airflow cavity, the number of the locking blocks being equal to the number of the second channels; any one of the locking blocks is misaligned with the air passage along the circumference of the air duct; the locking block extends into the airflow cavity, and when the air passage is aligned with the first channel, the locking block blocks the inner opening of the second channel to block the airflow between the second channel and the airflow cavity.

[0011] In one embodiment, the wind control component further includes a third cover plate, which covers the second cover plate onto the first cover plate along the axial direction of the air duct, and the third cover plate is circumferentially limited to the first cover plate; the third cover plate is provided with a second through hole; when the air duct is aligned with the second channel, the second through hole is aligned with the first through hole, at which time the airflow in the airflow channel flows through the first air outlet, the air duct, the second channel, the airflow cavity, the first through hole, the second through hole, and the second air outlet.

[0012] In one embodiment, a connecting post extending along the axial direction of the air duct is provided between the first cover plate and the third cover plate. The connecting post is connected to at least one of the first cover plate and the third cover plate. The connecting post passes through the second cover plate so that the second cover plate can be rotatably connected to the first cover plate or the third cover plate around the connecting post.

[0013] In one embodiment, the third cover plate is provided with a mounting cavity, and the second cover plate is installed in the mounting cavity. The side wall of the mounting cavity is provided with a plurality of third through holes arranged at intervals along the circumference of the air duct. The number of the third through holes is equal to the number of the first channels. When the second cover plate is rotated to align the air duct with the first channel, the third through hole aligns with the outlet of the first channel. At this time, the airflow in the airflow channel flows through the first air outlet, the air duct, the first channel, the third through hole, and the third air outlet.

[0014] In one embodiment, one of the sides of the second cover plate facing the third cover plate and the other of the sides of the third cover plate facing the second cover plate is provided with a protrusion, and the other is provided with an arc-shaped groove. The protrusion is movably engaged with the arc-shaped groove, and the protrusion can slide along the circumference of the air duct within the arc-shaped groove to limit the rotation angle of the second cover plate. When the protrusion abuts against one end of the arc-shaped groove, the air passage is aligned and connected with the first channel. When the protrusion abuts against the other opposite end of the arc-shaped groove, the air passage is aligned and connected with the second channel.

[0015] In one embodiment, the combined blowing and suction dust collector further includes a second dust collection pipe, which is detachably covered by the second air outlet. The edge of the second dust collection pipe is provided with a groove and a limiting part. In the first state, the second dust collection pipe can be detachably fastened to the second air outlet along the axial direction of the air duct, so that the protrusion is aligned and engaged with the groove. At this time, the second dust collection pipe and the second cover plate are circumferentially limited. Rotating the second dust collection pipe can drive the second cover plate to rotate synchronously, so that the limiting part moves synchronously to be mutually limited with the third cover plate along the axial direction of the air duct.

[0016] In one embodiment, the blower-suction dual-purpose dust collector further includes a first dust collection pipe, which is detachably connected to the first air outlet.

[0017] As can be seen from the above technical solution, the embodiments of this utility model have at least the following advantages and positive effects:

[0018] This utility model provides a dual-purpose blower / vacuum dust collector with multi-directional air intake or exhaust. Users can easily switch the airflow direction between forward and side intake / exhaust by simply rotating the second cover, thus conveniently adjusting the airflow direction to adapt to more usage scenarios and meet diverse user needs. For example, if a user inertia points the second air outlet towards their face, a simple rotation of the second cover quickly adjusts the airflow direction, avoiding discomfort caused by direct airflow or suction towards the face. Furthermore, this dual-purpose blower / vacuum dust collector, by switching the airflow direction within the air duct, can change the airflow strength between forward and side exhaust without adjusting the motor speed, adapting to a wider range of dust collection environments.

[0036] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0038] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "setup," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] This application provides a dual-purpose blower and suction dust collector 10 (hereinafter referred to as dust collector 10) with multi-directional air outlet or multi-directional air inlet. Since the dust collector 10 has air outlets at both the end face and the side face, it can achieve multi-directional air inlet or multi-directional air outlet, thereby meeting more blower and suction dust removal and cleaning needs.

[0040] Reference Figure 1 and Figure 2The dust collector 10 includes a duct 100, a fan (not shown), an air control component 200, a first dust collection pipe 300, and a second dust collection pipe 400. The fan is located inside the duct 100 and generates airflow within the duct 100 upon startup. The air control component 200 is located at one end of the duct 100 and is used to adjust the airflow direction within the duct 100. The first dust collection pipe 300 and the second dust collection pipe 400 are respectively installed on opposite sides of the duct 100 along its axial direction. It should be noted that, depending on the airflow direction within the duct 100, if one of the first dust collection pipe 300 or the second dust collection pipe 400 is installed at the air inlet of the duct 100, it functions as a suction device; if the other is installed at the air outlet of the duct 100, it functions as a blowing device. Alternatively, it can also be used for blowing and drying. It should be understood that in this application, both the first dust collection pipe 300 and the second dust collection pipe 400 are detachably installed on the air duct 100. They can be sold as a combination or manufactured and sold separately as independent products or parts. Therefore, for the dust collector 10 of this application, it is not limited whether the dust collector 10 includes the first dust collection pipe 300 or whether it includes the second dust collection pipe 400. That is, the dust collector 10 of this application can include both the first dust collection pipe 300 and the second dust collection pipe 400, or the dust collector 10 can include only one of the first dust collection pipe 300 and the second dust collection pipe 400, or the dust collector 10 can exclude either the first dust collection pipe 300 or the second dust collection pipe 400.

[0041] Reference Figure 1 and Figure 2The ventilation duct 100 has a first end 110 and a second end 120 opposite to each other along its axial direction, and an airflow channel 101 formed between the first end 110 and the second end 120. The airflow channel 101 forms a first air outlet 102 at the first end 110, and a second air outlet 103 and a third air outlet 104 at the second end 120. The second air outlet 103 is located on the axial end face of the second end 120 away from the first end 110, and the third air outlet 104 is located on the outer peripheral wall of the second end 120. The second end 120 is capable of changing the airflow direction. The first air outlet 102 is used to install a first dust removal pipe 300, and the second air outlet 103 is used to install a second dust removal pipe 400. A fan is installed in the air duct 100 and, upon startup, generates airflow within the airflow channel 101. The airflow flows between the first end 110 and the second end 120. When the airflow generated by the fan within the airflow channel 101 flows from the first end 110 to the second end 120 (i.e., the first end 110 is the air inlet, the first air outlet 102 is the air inlet, the second end 120 is the air outlet, and the second air outlet 103 and the third air outlet 104 are the air outlets), the dust collector 10 is a multi-directional airflow dust collector 10. When the airflow generated by the fan within the airflow channel 101 flows from the second end 120 to the first end 110 (i.e., the second end 120 is the air inlet, the second air outlet 103 and the third air outlet 104 are the air inlets, the first end 110 is the air outlet, and the first air outlet 102 is the air outlet), the dust collector 10 is a multi-directional airflow dust collector 10.

[0042] Here, the utility model of this solution will be further described using the multi-directional air outlet dust collector 10 as an example. It should be noted that for the multi-directional air inlet dust collector 10, the utility model of this solution can be clearly understood simply by changing the airflow direction (changing the outlet to the inlet).

[0043] refer to Figure 3 The wind control component 200 is disposed at the second end 120 and located on the path of the airflow channel 101. The wind control component 200 includes a first cover plate 210 and a second cover plate 220. The first cover plate 210 is provided with an air passage 211 for airflow in the airflow channel 101 to flow between the first end 110 and the second end 120. The second cover plate 220 is provided with a first channel 221 and a second channel 222 on the side facing the first cover plate 210. (Refer to reference) Figures 4-7 The second cover plate 220 is rotatably connected to the first cover plate 210 along the circumference of the air duct 100. The first cover plate 210 is circumferentially limited to the air duct 100. The second cover plate 220 can rotate relative to the first cover plate 210 in a first state. Figure 4 and Figure 6 (as shown) and the second state ( Figure 5 and Figure 7 Switch between (as shown). Combined with Figure 4 and Figure 6When the second cover plate 220 rotates to the first state, the second air vent 103 is blocked. The two ends of the first channel 221 are respectively aligned and connected to the air duct 211 and the third air vent 104. The airflow in the airflow channel 101 flows through the first air vent 102 in sequence (combined with...). Figure 2 ), air duct 211, first channel 221, third air outlet 104 to the external environment. Combined with Figure 5 and Figure 7 When the second cover plate 220 rotates to the second state, the third air vent 104 is blocked, and the two opposite ends of the second channel 222 are respectively aligned and connected to the air duct 211 and the second air vent 103. The airflow in the airflow channel 101 flows sequentially through the first air vent 102 (in conjunction with...). Figure 2 The air duct 211, second channel 222, and second air outlet 103 lead to the external environment. Rotating the second cover 220 can switch the air outlet direction of the second end 120. Air can exit through the second air outlet 103, defined as axial air outlet of the air duct 100; or it can exit through the third air outlet 104, defined as radial air outlet of the air duct 100. Air can also exit through both the second air outlet 103 and the third air outlet 104 simultaneously, defined as oblique air outlet of the air duct 100 at the second end 120. Based on common sense, at the same motor speed, axial air outlet has the strongest airflow, followed by oblique air outlet, and radial air outlet has the weakest airflow. Of course, under the same airflow conditions, the user can also change the airflow strength by adjusting the motor speed.

[0044] The dust collector 10 provided in this application allows users to easily switch the air duct 100 between axial, radial, or oblique airflow directions by simply rotating the second cover plate 220. This facilitates adjustment of the airflow direction within the air duct 100, adapting to various dust collection scenarios and meeting diverse user needs. For example, if a user inertia points the second air outlet 103 towards their face, a simple rotation of the second cover plate 220 quickly adjusts the airflow direction, preventing discomfort caused by direct airflow from the air duct 100 onto the face. Furthermore, by switching the airflow direction within the air duct 100, the dust collector 10 can alter the axial or radial airflow strength without adjusting the motor speed, adapting to a wider range of dust collection environments and enhancing the practicality of the dust collector 10.

[0045] Preferably, in conjunction with reference Figures 4-7In this embodiment, the number of air ducts 211, first channels 221, and second channels 222 are multiple and identical. Air ducts 211 are spaced apart on the first cover plate 210 along the circumference of the air duct 100. First channels 221 and second channels 222 are staggered along the circumference of the air duct 100 on the second cover plate 220. When the second cover plate 220 is rotated circumferentially to the first state, the multiple air ducts 211 are aligned one-to-one with the inlets of the multiple first channels 221, while the inlets of the multiple second channels 222 are completely covered and blocked by the spaced portions of the multiple air ducts 211 on the first cover plate 210, thereby blocking the second air outlet 103. When the second cover plate 220 is rotated circumferentially to the second state, the multiple air ducts 211 are aligned one-to-one with the inlets of the multiple second channels 222, while the inlets of the multiple first channels 221 are completely covered and blocked by the spaced portions of the multiple air ducts 211 on the first cover plate 210, thereby blocking the third air outlet 104. It should be understood that the air duct 211, the first channel 221, and the second channel 222 are arranged circumferentially along the air duct 100, ensuring uniform airflow along a ring shape, balanced airflow, and better dust removal or drying effects. It should also be understood that, without considering balanced airflow, this application does not limit the number or distribution of the air duct 211, the first channel 221, and the second channel 222, as long as rotating the second cover 220 allows switching between the first and second states. Here, the first cover 210 can be integrally formed on the inner wall of the airflow channel 101 at the second end 120 of the air duct 100, or it can be detachably installed on the inner wall of the airflow channel 101. Any scheme that satisfies the circumferential limiting of the first cover 210 and the air duct 100 should fall within the protection scope of this application.

[0046] Preferably, refer to Figure 3 In this embodiment, the second cover plate 220 has an airflow cavity 223 on the side facing the first cover plate 210, and the first cover plate 210 covers the opening side of the airflow cavity 223. A portion of the outer wall of the airflow cavity 223 is recessed inward to form the first channel 221 described above, and the first channel 221 is located on the outer periphery of the airflow cavity 223; a portion of the inner wall of the airflow cavity 223 is recessed outward to form the second channel 222 described above, and the second channel 222 communicates with the interior of the airflow cavity 223. Additionally, a first through hole 224 is provided on the bottom wall of the airflow cavity 223, combined with... Figure 5 and Figure 7 When the second cover plate 220 rotates to the second state, that is, when the openings of the air passage 211 and the second channel 222 are aligned, the airflow passage 101 connects with the airflow chamber 223 through the air passage 211. At this time, the air in the airflow passage 101 flows sequentially through the first air outlet 102 (in conjunction with...). Figure 2The air passage 211, the second channel 222, and the first through hole 224 lead to the external environment. It should be understood that the air passage 211, the first channel 221, and the second channel 222 all serve to allow airflow and can take various forms such as holes, grooves, slits, and notches. It is important to understand that the airflow cavity 223 facilitates the processing of the second cover plate 220 to form the first channel 221 and the second channel 222, and also reduces the weight of the second cover plate 220. In this application, the first channel 221 and the second channel 222 are formed by grooves formed by recesses in the inner and outer sidewalls of the airflow cavity 223. In other embodiments, if the second cover plate 220 does not have the airflow cavity 223, the first channel 221 and the second channel 222 can also be formed by directly creating staggered holes on the side circumference. In this case, the second channel 222 would have a notch carved into the side circumference of the second cover plate 220, making the processing more complex, and the second cover plate 220 would then be a solid, thick plate with a larger weight. Therefore, in this application, without considering the ease of processing the first channel 221 and the second channel 222 or the mass and size of the second cover plate 220, the setting of the airflow cavity 223 is not limited.

[0047] Preferably, in conjunction with reference Figure 2 and Figure 3 In this embodiment, the first cover plate 210 has multiple protruding locking blocks 212 on the side facing the airflow cavity 223. The number of locking blocks 212 is equal to the number of second channels 222, and they are spaced apart circumferentially (along the circumferential direction of the air duct 100) on the first cover plate 210. Along the circumferential direction of the air duct 100, any one locking block 212 is offset from the airway 211. Combined with... Figure 6 and Figure 7 Multiple locking blocks 212 extend into the airflow cavity 223. When the air passage 211 aligns with the opening of the first channel 221 ( Figure 6 As shown), the locking block 212 blocks the inner opening of the second channel 222 to prevent airflow between the second channel 222 and the airflow cavity 223; when the air passage 211 and the opening of the second channel 222 are aligned, the locking block 212 is offset from the second channel 222 and abuts against the inner wall of the airflow cavity 223. Figure 7 As shown, the second channel 222 is connected to the airflow cavity 223, and the design of the locking block 212 allows the first cover plate 210 and the second cover plate 220 to engage. It should be understood that the design of the locking block 212 engaging with the airflow cavity 223 not only facilitates the user's assembly of the first cover plate 210 and the second cover plate 220, but also, in the first state, the locking block 212 can block the second channel 222 to further block the second air vent 103, ensuring that the airflow in the airflow channel 101 flows as far as possible only to the third air vent 104. In this application, the presence or absence of the locking block 212 is not limited.

[0048] Preferably, in conjunction with reference Figure 2 and Figure 3In this embodiment, the wind control component 200 further includes a third cover plate 230. The third cover plate 230 covers the second cover plate 220 onto the first cover plate 210 along the axial direction of the air duct 100, and the third cover plate 230 and the first cover plate 210 are circumferentially limited, that is, the second cover plate 220 can rotate relative to the first cover plate 210 and the third cover plate 230. The third cover plate 230 is provided with a second through hole 231, and the first through hole 224 can be aligned or misaligned with the second through hole 231 as the second cover plate 220 rotates. When the second cover plate 220 rotates to the second state, that is, when the air passage 211 is aligned with the second channel 222, the first through hole 224 is aligned with the second through hole 231. At this time, the airflow in the airflow passage 101 flows sequentially through the first air outlet 102, the air passage 211, the second channel 222, the first through hole 224, the second through hole 231, and the second air outlet 103 to the external environment. Here, the number of first through holes 224 and second through holes 231 are the same, and they are both evenly arranged along the circumference of the air duct 100 to achieve uniform airflow and provide users with stable and balanced wind force. It should be understood that the third cover plate 230 is provided both to facilitate user operation of the rotation of the second cover plate 220 and to improve the assembly stability between the various components of the wind control assembly 200. Therefore, without considering the assembly stability of the wind control assembly 200 and the rotation operation of the second cover plate 220, the presence or absence of the third cover plate 230 is not limited in this application.

[0049] Preferably, refer to Figure 3 In this embodiment, a connecting post 232 extending axially along the air duct 100 is provided between the first cover plate 210 and the third cover plate 230. The connecting post 232 is connected to the third cover plate 230 and passes through the second cover plate 220, so that the second cover plate 220 can be rotatably connected to the third cover plate 230 around the connecting post 232. Because the first cover plate 210 and the third cover plate 230 are circumferentially limited, the second cover plate 220 can also be rotatably connected to the first cover plate 210 around the connecting post 232. It is worth noting that the same rotatable connection effect can be achieved by connecting the connecting post 232 to at least one of the first cover plate 210 and the third cover plate 230. In addition, it should be understood that the connecting post 232 is a specific implementation method to achieve the rotatable connection of the second cover plate 220. In this application, the presence or absence of the connecting post 232 is not limited. As long as the specific connection method of the second cover plate 220 being rotatably connected to the first cover plate 210 or the third cover plate 230 is satisfied, it should fall within the protection scope of this application.

[0050] Preferably, in conjunction with reference Figure 3 and Figure 6In this embodiment, the third cover plate 230 is provided with a mounting cavity 233, and the second cover plate 220 is installed in the mounting cavity 233. The side wall of the mounting cavity 233 is provided with a plurality of third through holes 234 arranged at intervals along the circumference of the air duct 100. The third through holes 234 are aligned and connected to the third air outlet 104. The number of third through holes 234 is equal to the number of first channels 221. When the second cover plate 220 is rotated to the point where the air passage 211 is aligned with the opening of the first channel 221, the third through holes 234 are located at the outlet of the first channel 221. At this time, the airflow in the airflow channel 101 flows sequentially through the first air outlet 102, the air passage 211, the first channel 221, the third through holes 234, and the third air outlet 104 to the external environment. It should be understood that the mounting cavity 233 is provided to improve the assembly stability of the air control component 200. The sidewall of the mounting cavity 233 rotates synchronously with the first cover plate 210 and the third cover plate 230, requiring a third through hole 234 adapted to the third air outlet 104 and the first channel 221 to achieve airflow communication between them. Therefore, in this application, without considering the assembly stability of the air control component 200, the presence or absence of the mounting cavity 233 and the third through hole 234 are not limited.

[0051] Preferably, in conjunction with reference Figure 2 and Figure 3 In this embodiment, the second cover plate 220 has a protrusion 225 on the side facing the third cover plate 230, and the third cover plate 230 has an arc-shaped groove 235 on the side facing the second cover plate 220. The protrusion 225 is movably engaged with the arc-shaped groove 235 (in conjunction with...). Figure 8The second cover plate 220 rotates, causing the protrusion 225 to slide circumferentially within the arc-shaped groove 235 along the air duct 100, thereby limiting the rotation angle of the second cover plate 220. Specifically, when the protrusion 225 abuts against one end of the arc-shaped groove 235, the air passage 211 is aligned with the first channel 221, and the third through hole 234 is aligned with the third air outlet 104; when the protrusion 225 abuts against the other opposite end of the arc-shaped groove 235, the air passage 211 is aligned with the second channel 222, and the first through hole 224 is aligned with the second through hole 231. It should be noted that the protrusion 225 and the arcuate groove 235 cooperate to limit the rotation angle of the second cover plate 220. Their positions can be interchanged to achieve the same technical effect. The protrusion 225 can be provided on one side of the second cover plate 220 facing the third cover plate 230, and the arcuate groove 235 on the other side of the third cover plate 230 facing the second cover plate 220. It should be understood that limiting the rotation angle of the second cover plate 220 is for convenient positioning, ensuring that the air passage 211 is fully aligned and connected with the first channel 221 or the second channel 222. During the rotation of the second cover plate 220, the air passage 211 can also simultaneously connect with both the first channel 221 and the second channel 222. Therefore, if the ease of rotational positioning of the second cover plate 220 is not considered, the presence or absence of the protrusion 225 and the arcuate groove 235 is not limited in this application. Secondly, in this application, the specific implementation method of limiting the rotation angle of the second cover plate 220 is not limited. For example, in other embodiments, it can also be achieved by the cooperation of side wall grooves and protrusions.

[0052] Preferably, in conjunction with reference Figure 1 and Figure 9 In this embodiment, the dust collector 10 includes the previously mentioned second dust collection pipe 400, which is detachably fitted onto the second air outlet 103. The edge of the second dust collection pipe 400 is provided with a slot 410 and a limiting part 420. The protrusion 225 penetrates the arc-shaped groove 235 and extends out of the arc-shaped groove 235 to the side opposite to the second cover plate 220. Figure 8 (As shown), for the user to operate. When the user operates the protruding block 225 and rotates the second cover plate 220 to the first state, the air passage 211 is aligned with the first channel 221, the third through hole 234 is aligned and connected with the third air outlet 104, the second air outlet 103 is blocked, and the dust collector 10 axially discharges air. When the second dust collection pipe 400 is installed on the second air outlet 103 along the axial direction of the air duct 100, the protruding block 225 extends out of the arc-shaped groove 235 and is aligned and engaged in the slot 410 ( Figure 9As shown), the second dust removal pipe 400 and the second cover plate 220 are circumferentially limited. The user can rotate the second dust removal pipe 400 to drive the second cover plate 220 to rotate synchronously. In addition, the limiting part 420 can move synchronously to limit each other with the third cover plate 230 along the axial direction of the air duct. At this time, the second cover plate 220 is in the second state, the air passage 211 is aligned and connected to the second channel 222, the third air outlet 104 is blocked, the first through hole 224 is aligned with the second through hole 231, and the airflow in the airflow channel 101 flows sequentially through the first air outlet 102, the air passage 211, the second channel 222, the first through hole 224, the second through hole 231, the second air outlet 103, and the second dust removal pipe 400 to the external environment for dust blowing and cleaning. If the airflow direction is reversed, it is dust suction cleaning.

[0053] For details, please refer to Figure 10 The limiting part 420 and the third cover plate 230 each have a limiting protrusion 226 and a limiting groove 421. When the user rotates the second dust removal pipe 400, the limiting protrusion 226 is aligned and engaged within the limiting groove 421, thus restricting the relative movement (rotation and movement) between the second dust removal pipe 400 and the third cover plate 230. If the user needs to remove the second dust removal pipe 400, they need to apply force to rotate it, causing the limiting protrusion 226 to disengage from the limiting groove 421, thereby releasing the restriction on the relative movement between the second dust removal pipe 400 and the third cover plate 230. It should be understood that other methods of restricting the relative movement between the second dust removal pipe 400 and the third cover plate 230 should also be protected in this application; therefore, the presence or absence of the limiting protrusion 226 and the limiting groove 421 is not limited. Here, the second dust removal pipe 400 can use a nozzle to achieve the dust blowing function. The shape of the nozzle and the outlet shape are not limited, and the implementation form of the second dust removal pipe 400 is not limited.

[0054] Preferably, refer to Figure 1 In this embodiment, the dust collector 10 further includes the aforementioned first dust collection pipe 300, which is detachably connected to the first air outlet 102. The first dust collection pipe 300 includes a detachably connected suction nozzle 310 and a suction pipe 320. The suction nozzle 310 is detachably connected to one end of the suction pipe 320, and the end of the suction pipe 320 away from the suction nozzle 310 is detachably connected to the first air outlet 102. It should be understood that the implementation of the first dust collection pipe 300 is not limited in this application. If the airflow direction is reversed, the connection positions of the first dust collection pipe 300 and the second dust collection pipe 400 can be interchanged.

[0055] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
