[0035] The terms “first,” “second,” “third,” etc., are used merely to distinguish elements with similar properties, not to indicate or imply relative importance or a specific order.

[0036] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0037] like Figure 1 and Figure 3 As shown in the figure, this embodiment provides an air outlet structure with switchable air outlet direction, including an air outlet base 1 and a guide unit 2. The air outlet base 1 has a first end 11 and a second end 12 opposite to each other. The air outlet base 1 is hollow inside, and an opening 13 communicating with the interior of the air outlet base 1 is opened on the first end 11. An air inlet 14 communicating with the interior of the air outlet base 1 is opened on the side wall between the first end 11 and the second end 12. The air inlet 14, the hollow interior and the opening 13 of the air outlet base 1 together form an airflow channel. The airflow flows into the hollow interior of the air outlet base 1 from the air inlet 14, and then flows from the hollow interior of the air outlet base 1 to the opening 13, thereby discharging the airflow. The guide unit 2 includes a guide post 22 and a guide plate 21. The guide post 22 is installed inside the air outlet base 1 and is arranged in the direction of extension from the first end 11 to the second end 12 of the air outlet base 1. The guide plate 21 has an opening in the middle so that it is fitted onto the guide post 22, allowing the guide plate 21 to move back and forth between the first end 11 and the second end 12 of the air outlet base 1. The cross-sectional area of ​​the guide plate 21 is smaller than the area of ​​the opening 13 on the first end 11, forming a gap between the guide plate 21 and the air outlet base 1 at the opening 13.

[0038] In the structure provided in this embodiment, the air inlet 14 of the air outlet base 1 is opened on the side wall between the first end 11 and the second end 12 of the air outlet base 1. External airflow flows into the interior of the air outlet base 1 through the air inlet 14 and flows out through the opening 13 of the air outlet base 1. When the airflow flows in the air outlet base 1, the airflow path is changed by the guide plate 21, thereby changing the air outlet direction of the air outlet base 1. For example, when the guide plate 21 moves on the guide post 22 to the second end 12 of the air outlet base 1, the guide plate 21 does not interfere with the airflow flowing in through the air inlet 14 on the side wall of the air outlet base 1. The airflow gathers in the air outlet base 1 and flows out through the opening 13 of the air outlet base 1. That is, the airflow direction is the axial direction of the opening 13 of the air outlet base 1. When the guide plate 21 moves on the guide post 22 to the first end 11 of the air outlet base 1, the guide plate 21 is located at the opening 13 of the air outlet base 1. At this time, the airflow is gathered in the air outlet base 1 from the air inlet 14 of the air outlet base 1 and flows out through the opening 13 of the air outlet base 1. Due to the obstruction of the guide plate 21, the airflow flows out through the gap between the guide plate 21 and the air outlet base 1, thereby changing the air outlet direction of the air outlet base 1 and preventing the airflow from blowing directly on the user.

[0039] The guide plate 21 has a guide surface segment 211 on its surface facing the second end 12, which is connected to the edge of the guide plate 21. The guide surface segment 211 gradually moves away from the second end 12 from the middle of the guide plate 21 towards its edge. The guide surface segment 211 can extend from the middle of the guide plate 21 to its edge, or it can extend from a position between the middle of the guide plate 21 and its edge to its edge. By providing the guide surface segment 211 on the guide plate 21, the guiding effect on the airflow can be further enhanced, causing the airflow to flow obliquely at the gap between the guide plate 21 and the air outlet base 1, thus avoiding direct airflow onto the user.

[0040] Furthermore, the air outlet base 1 is provided with a guide portion 16 around the periphery of the opening 13 at the first end 11. The guide portion 16 extends obliquely away from the opening 13, and the cross-sectional area of ​​the guide portion 16 gradually increases from the second end 12 to the first end 11. The guide portion 16 at the opening 13 of the air outlet base 1 can further enhance the guiding effect of the airflow, and when the airflow is blown out obliquely under the guidance of the guide plate 21, it can prevent the air outlet base 1 from obstructing the oblique blowing of the airflow.

[0041] In summary, the switchable air outlet structure provided in this embodiment can change the air outlet direction of the air outlet base 1. When a direct blowing mode is required, the guide plate 21 is moved to the second end 12 of the air outlet base 1. The guide plate 21 does not guide the airflow, and the airflow blows directly. When it is necessary to change the airflow direction, the guide plate 21 is moved to the second end 12 of the air outlet base 1 to prevent the airflow from blowing directly on the user.

[0042] like Figure 4 , Figure 7 and Figure 8 As shown, this embodiment also provides a blower / vacuum combo 3, including a combo body 31, an air outlet 32, and an air outlet structure with switchable air outlet direction as described above. The combo body 31 has an air inlet end 33 and an air outlet end 34, which are the two ends where airflow enters and exits in the combo body 31. An air filter device 39, a vacuum cleaner motor 36, and a battery 37 are installed inside the combo body 31. The air filter device 39 is installed at the air inlet end 33, and the battery 37 provides power to the vacuum cleaner motor 36. The vacuum cleaner motor 36 provides power to draw air in from the air inlet end 33, and after passing through the air filter device 39, it flows through the internal air passage 35 of the combo body 31 to the air outlet end 34. The switchable air outlet structure is installed at the air outlet end 34 and the air inlet 14 of the air outlet base 1 is connected to the internal air passage 35 of the integrated body 31. The air outlet nozzle 32 is detachably installed at the opening 13 of the first end 11 of the air outlet base 1. When the air outlet nozzle 32 is installed on the air outlet base 1, the air outlet nozzle 32 can push the guide plate 21 to move towards the second end 12 of the air outlet base 1.

[0043] With the above structure, when using the blowing function of the blower / vacuum combo 3, the air outlet 32 ​​is installed on the air outlet base 1. When the air outlet 32 ​​is installed on the air outlet base 1, it pushes the guide plate 21 to move towards the second end 12 of the air outlet base 1. At this time, the guide plate 21 does not guide the airflow flowing into the air inlet 14 of the air outlet base 1, and the airflow blows out from the opening 13 of the air outlet base 1 in a direct blowing mode. When using the vacuuming function of the blower / vacuum combo 3, the air outlet 32 ​​is removed from the air outlet base 1. At this time, the guide plate 21 can move to the first end 11 of the air outlet base 1 to guide the airflow flowing out from the opening 13 of the air outlet base 1, avoiding direct airflow to the user.

[0044] Specifically, regarding the detachable installation of the air outlet 32 ​​on the air outlet base 1, such as... Figure 1 , Figure 2 , Figure 9 and Figure 10As shown, the inner sidewall of the air outlet base 1 is provided with a snap-fit ​​groove 15, which extends circumferentially along the sidewall of the air outlet base 1. A notch 151 is provided near the first end 11 of the snap-fit ​​groove 15, and a narrow opening 153 is provided away from the first end 11. The axial width of the narrow opening 153 is smaller than the overall axial width of the snap-fit ​​groove 15, and the circumferential length of the narrow opening 153 is greater than the circumferential length of the notch 151. A locking block is formed on one side of the notch 151 corresponding to the position of the narrow opening 153. The outer sidewall of the air outlet nozzle 32 is provided with a snap-fit ​​part, the size of which is smaller than the size of the notch 151. After the snap-fit ​​part of the air outlet nozzle 32 passes through the notch 151, rotating the air outlet nozzle 32 causes the snap-fit ​​part to slide in the narrow opening 153, thereby detachably snapping the air outlet nozzle 32 onto the air outlet base 1. When installing the air outlet nozzle 32, align the snap-fit ​​portion of the air outlet nozzle 32 with the notch 151 of the snap-fit ​​groove 15 of the air outlet base 1. Push the air outlet nozzle 32 inward along the axial direction of the integrated body 31 so that the snap-fit ​​portion enters the snap-fit ​​groove 15 of the air outlet base 1. Then rotate the air outlet nozzle 32 so that the snap-fit ​​portion of the air outlet nozzle 32 slides in the narrow opening 153 of the air outlet base 1, so that the snap-fit ​​portion of the air outlet nozzle 32 and the notch 151 of the snap-fit ​​groove 15 are not on the same axis, thereby fixing the air outlet nozzle 32 to the air outlet base 1. When it is necessary to remove the air outlet nozzle 32, rotate the air outlet nozzle 32 in the opposite direction so that the snap-fit ​​portion of the air outlet nozzle 32 slides in the snap-fit ​​groove 15. When the snap-fit ​​portion of the air outlet nozzle 32 slides to the notch 151 of the snap-fit ​​groove 15, the air outlet nozzle 32 can be removed from the air outlet base 1. The detachable connection of the air outlet 32 ​​facilitates the switching of the blower and vacuum combo 3 modes, and can also be adapted to various different specifications of air outlet 32. Choose the appropriate model of air outlet 32 ​​according to the usage scenario.

[0045] Furthermore, to further ensure a secure connection between the air outlet 32 ​​and the air outlet base 1, a fixing block 152 is provided on one of the side walls of the snap-fit ​​groove 15 near the second end 12 and the snap-fit ​​portion of the air outlet 32, and a fixing groove 324 is provided on the other side wall of the snap-fit ​​groove 15 near the second end 12 and the snap-fit ​​portion of the air outlet 32. In this embodiment, the fixing groove 324 is provided on the air outlet 32, and the fixing block 152 is provided in the snap-fit ​​groove 15 of the air outlet base 1. The fixing block 152 has a first guide surface 1521 and a second guide surface 1522. The first guide surface 1521 can be an inclined surface or an arc surface. Furthermore, the connection 1523 between the first guide surface 1521 and the second guide surface 1522 is a smooth curved surface. The fixing groove 324 matches the shape of the fixing block 152. The fixing groove 324 has a third guide surface 325 and a fourth guide surface 326 that match the shapes of the first guide surface 1521 and the second guide surface 1522. The transition 327 between the third guide surface 325 and the fourth guide surface 326 is a smooth curved surface. When the snap-fit ​​part rotates in the snap-fit ​​groove 15, the fixing block 152 moves into the fixing groove 324 to achieve snap-fit. Through the cooperation of the fixing block 152 and the fixing groove 324, the air outlet 32 ​​can be firmly connected when installed on the air outlet base 1, preventing the air outlet 32 ​​from falling off the air outlet base 1 during use.

[0046] In addition, to facilitate the adaptive change of the guide plate 21 when switching between blowing and vacuuming modes during the installation and removal of the air outlet 32 ​​of the blower / vacuum combo unit 3, the air outlet 32 ​​has a connecting end 321 and an exhaust end 322, forming an air passage between the connecting end 321 and the exhaust end 322. The connecting end 321 has a protrusion 323. When the air outlet 32 ​​is installed on the air outlet base 1, the protrusion 323 of the connecting end 321 pushes the guide plate 21 to move towards the second end 12 of the air outlet base 1. Therefore, the guide plate 21 can be automatically pushed towards the second end 12 of the air outlet base 1 during the installation of the air outlet 32, without the need for adjustment of the guide plate 21.

[0047] At the same time, such as Figure 3As shown, the guide unit 2 also includes an elastic reset member 23. The elastic reset member 23 has two opposing ends. One end of the elastic reset member 23 abuts against the second end 12 of the air outlet base 1, and the other end of the elastic reset member 23 abuts against the guide plate 21. When the air outlet nozzle 32 is installed on the air outlet base 1, it compresses the elastic reset member 23 during the process of pushing the guide plate 21 to the second end 12. When the air outlet nozzle 32 is removed from the air outlet base 1, the elastic reset member 23 elastically deforms and pushes the guide plate 21 back to the first end 11. That is, when the blow-and-suction machine 3 switches to the blowing mode, the air outlet nozzle 32 is installed on the air outlet base 1. The air outlet nozzle 32 pushes the guide plate 21 to move to the second end 12 of the air outlet base 1. At this time, the elastic reset member 23 is compressed and elastically deformed. The air outlet nozzle 32 pushes the guide plate 21 to keep the guide plate 21 at the second end 12 of the air outlet base 1. At this time, the guide plate 21 has no guiding effect on the airflow in the air outlet base 1, and the airflow blows directly. When the blower and vacuum unit 3 switches to vacuuming mode, the air outlet 32 ​​is removed. At this time, the elastic reset member 23 elastically deforms and pushes the guide plate 21 to move toward the first end 11 of the air outlet base 1, and keeps the guide plate 21 at the first end 11 of the air outlet base 1. At this time, the guide plate 21 guides the airflow in the air outlet base 1 to prevent the airflow flowing out of the air outlet base 1 from blowing directly on the user.

[0048] In addition, if Figure 3 As shown, a first mounting groove 17 and a second mounting groove 18 are respectively provided on the second end 12 of the air outlet base 1 and the guide plate 21. The two ends of the elastic reset member 23 abut against the first mounting groove 17 and the second mounting groove 18 respectively. In this way, when the guide plate 21 moves on the guide post 22, the elastic reset member 23 can stably support the guide plate 21.

[0049] The elastic reset element 23 may be a spring, preferably a tower spring, which can more stably support the guide plate 21.

[0050] like Figures 4 to 6As shown, the blow-and-vacuum combo unit 3 has a mounting part 38 at one end, and an air inlet end 33 located in the mounting part 38. The mounting part 38 is hollow inside and has an air filter device 39. The mounting part 38 is detachably mounted on the blow-and-vacuum combo unit 3. One of the mounting part 38 and the combo unit body 31 has a connecting part 4, and the other of the mounting part 38 and the combo unit body 31 has a connecting groove 381. In this embodiment, the connecting groove 381 is located in the mounting part 38, and the connecting part 4 is located in the combo unit body 31. The connecting groove 381 has a slot 382 on the side closer to the combo unit body 31, and a retaining groove 385 on the side away from the combo unit body 31. The axial width of the retaining groove 385 is smaller than the overall axial width of the connecting groove 381, and the circumferential length of the retaining groove 385 is greater than the circumferential length of the slot 382. The connecting part 4 can pass through the slot 382 of the connecting groove 381 and slide in the retaining groove 385. When the air filter 39 needs to be replaced or repaired, rotate the mounting part 38 to align the connecting part 4 with the slot 382 of the connecting groove 381. At this time, the mounting part 38 and the integrated body 31 can be separated. When installing the mounting part 38, align the connecting part 4 with the slot 382 of the connecting groove 381, press the connecting part 4 into the connecting groove 381, and rotate the mounting part 38 or the integrated body 31 to make the connecting part 4 slide in the slot 385, thereby fixing the mounting part 38 and the integrated body 31 together.

[0051] Meanwhile, one of the connecting part 4 and the connecting groove 381 is provided with an inserting part, and the other of the connecting part 4 and the connecting groove 381 is provided with an inserting groove 41. In this embodiment, the inserting part is located in the connecting groove 381, and the inserting groove 41 is located in the connecting part 4. The inserting part has a fifth guide surface 383 and a sixth guide surface 384 connected to each other. The fifth guide surface 383 and the sixth guide surface 384 are smooth curved surfaces. The shape of the inserting groove 41 is adapted to the shape of the inserting part. When the connecting part 4 rotates into place in the connecting groove 381, the inserting part is inserted into the inserting groove 41, so that the mounting part 38 is firmly installed on the integrated body 31.

[0052] In summary, the blower-vacuum combo 3 provided in this embodiment can quickly switch the airflow direction when switching between blowing mode and vacuuming mode, thereby improving the user experience.

[0053] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
