[0041] One embodiment of this utility model provides a detachable blowing and suction device, see reference. Figures 1-12,include:

[0042] The main unit housing 1 has an air inlet 11 and an air outlet 12 at its two ends. A drive module 131 is installed inside the main unit housing 1. The drive module 131 is used to generate a drive airflow, which enters from the air inlet 11 and exits from the air outlet 12.

[0043] The conversion component 4 is disposed at the air inlet 11 or the air outlet 12. The conversion component 4 is detachably connected to the main housing 1. The port of the conversion component 4 is provided with a mounting groove 41. The inner side of the air inlet 11 and the air outlet 12 are both provided with mounting sliders 15. The mounting sliders 15 are slidably connected to the mounting grooves 41.

[0044] The vacuuming device 2 is detachably installed at the other end of the conversion component 4 to communicate with the main housing 1 to achieve the vacuuming function;

[0045] The blower 3 is detachably installed at the other end of the conversion component 4 to communicate with the main housing 1 to achieve the dust blowing function.

[0046] This application solves the problems of poor operation and unpleasant user experience in existing vacuum and blower dual-purpose devices. This application achieves quick installation and switching between the vacuuming device 2 and the blower device 3 on the main unit housing 1 by circumferentially setting mounting grooves 41 at both ends of the converter 4 and circumferentially setting mounting sliders 15 on the inner sides of the air inlet 11 and air outlet 12 of the main unit housing 1 through the sliding connection between the mounting grooves 41 and the mounting sliders 15. This improves operational convenience, allowing users to switch between vacuuming and blowing modes without additional tools, thus enhancing the user experience. In this embodiment, the main housing 1 includes a handle 14 and a mounting housing 13. A drive module 131 is installed inside the mounting housing 13. The handle 14 is for the user to hold. The mounting housing 13 is located above the handle 14. An air inlet 11 and an air outlet 12 are respectively provided at both ends of the mounting housing 13. An airflow direction indicator is provided on the mounting housing 13. The conversion component 4 is detachably installed at the air inlet 11 or the air outlet 12 of the mounting housing 13 through the mounting groove 41 and the mounting slider 15. When the conversion component 4 is installed at the air inlet 11, the dust collection device 2 is connected to the other end of the conversion component 4 so that the dust collection device 2 is connected to the air inlet 11 of the main housing 1 to realize the dust collection function of the dust collection device 2. When the conversion component 4 is installed at the air outlet 12, the blower device 3 is connected to the other end of the conversion component 4 so that the blower device 3 is connected to the air outlet 12 of the main housing 1 to realize the dust blowing function of the blower device 3. The vacuuming or blowing mode can be switched quickly and easily, improving operational convenience. Users can switch between vacuuming and blowing modes without the need for additional tools, enhancing the user experience. When the device is not in use, the vacuum cleaner 2 and blower 3 can be detached and stored together with the main unit housing 1, reducing storage space and making it easy to carry. The device can also be used as a fan when not in use for cleaning. It should be noted that in other embodiments, the handle 14 and the housing 13 can be detachable for easier storage and carrying, improving the product's portability.

[0047] Specifically, the surface of the adapter 4 is provided with an indicator arrow to facilitate users to quickly identify the installation direction during installation. The air inlet 11 and air outlet 12 of the mounting housing 13 are provided with unlock and lock marks to facilitate users to quickly judge the assembly status of the interface with visual prompts. When the air intake component is locked in place, the arrow mark on the air intake component is aligned with the lock mark; when the air intake component is disassembled, the arrow mark on the air intake component is rotated to be aligned with the unlock mark.

[0048] Furthermore, the drive module 131 includes a motor and fan blades. The motor drives the fan blades to rotate, creating negative pressure suction at the air inlet 11 and directional airflow at the air outlet 12. A battery and a control circuit board are installed inside the handle 14. The control circuit board is electrically connected to the motor and battery, respectively. The battery provides the power source for the motor's rotation. A wind speed adjustment switch 17 and a control switch 16 are also provided on the surface of the mounting housing 13. The wind speed adjustment switch 17 adjusts the airflow of the device, and the control switch 16 controls the start and stop of the device. Specifically, the wind speed adjustment switch 17 and the control switch 16 are electrically connected to the control circuit board inside the handle 14. The wind speed adjustment switch 17 and the control switch 16 are arranged opposite each other, with the wind speed adjustment switch 17 located on the front side of the mounting housing 13 and the control switch 16 located on the rear side. This arrangement allows the user to easily touch the wind speed adjustment switch 17 with their right index finger and simultaneously touch the control switch 16 with their right thumb, without significantly moving their wrist, thus improving the user experience and facilitating operation. Furthermore, a display screen 18 is provided on the side of the mounting housing 13 to display the current fan speed and mode, allowing the user to intuitively observe the current operating status of the device. In other embodiments, LED indicator lights may also be provided on the mounting housing 13 or the handle 14 to provide real-time feedback on the current operating status.

[0049] Specifically, when a user needs to use the device for vacuuming, the adapter 4 needs to be installed at the air inlet 11 of the mounting housing 13 first, and then the vacuuming device 2 needs to be installed at the other end of the adapter 4. Then, the device is started by pressing the control switch 16 on the back of the mounting housing 13 with the right thumb. At this time, the control circuit board receives the signal and activates the motor to run. The display screen 18 lights up simultaneously and displays the default fan speed and battery status. Users can press the wind speed adjustment switch 17 to adjust the air volume step by step (e.g., low, medium, and high). During the adjustment, the display screen 18 updates the current wind speed value in real time. When it is necessary to switch to dust blowing operation, press the control switch 16 again to turn off the device, and remove the dust suction device 2 and the conversion part 4 from the mounting housing 13. Then install the conversion part 4 to the air outlet 12 of the mounting housing 13, and install the blower 3 to the other end of the conversion part 4. Then press the control switch 16 again to start the device and repeat the above operation. After all the work is completed, press the control switch 16 to turn off the device, remove the blower 3 and the conversion part 4 from the mounting housing 13, and store the main housing 1, the blower 3, the dust suction device 2, and the conversion part 4.

[0050] Furthermore, the mounting groove 41 has a notch 411 for the mounting slider 15 to slide into. Specifically, the user aligns the mounting slider 15 at the air inlet or outlet 12 of the main unit housing 1 with the notch 411 on the conversion piece 4 and pushes it in along the axial direction of the main unit housing 1, so that the mounting slider 15 enters the mounting groove 41 through the notch 411. Then, the user only needs to rotate the conversion piece 4, and the mounting slider 15 can slide along the circumferential mounting groove 41 until it reaches the locking position, realizing a fixed connection and improving the convenience and efficiency of installation.

[0051] Furthermore, a limiting groove 151 is provided at the end of the mounting slider 15, and a limiting protrusion 412 adapted to engage with the limiting groove 151 is provided in the mounting groove 41. In this embodiment, the inner side of the limiting groove 151 is arc-shaped, and the limiting protrusion 412 extends longitudinally along the inner wall of the mounting groove 41, so that a double lock is formed between the main housing 1 and the conversion component 4, preventing it from falling off due to external force collision.

[0052] Specifically, when the vacuum cleaner 2 needs to be installed, the user aligns the adapter 4 with the air inlet 11 of the main unit housing 1, and rotates the adapter 4 circumferentially so that the mounting slider 15 at the air inlet 11 of the main unit housing 1 slides into the mounting groove 41 of the adapter 4 through the notch 411. When the mounting slider 15 is in the mounting groove 41, the adapter 4 and the main unit housing 1 are relatively positioned. When the adapter 4 is rotated further, the side wall of the mounting slider 15 is squeezed and deformed by the limiting protrusion 412 in the mounting groove 41. The limiting slot 151 and the limiting protrusion 412 are engaged and fixed to lock the adapter 4 and the main unit housing 1. Furthermore, the vacuum cleaner 2... At the other end of the conversion component 4, the vacuum cleaner 2 is rotated circumferentially so that the mounting slider 15 of the vacuum cleaner 2 slides into the mounting groove 41 at the other end of the conversion component 4 through the notch 411. When the mounting slider 15 is located in the mounting groove 41, the conversion component 4 and the vacuum cleaner 2 are positioned relative to each other. When the conversion component 4 is rotated further, the side wall of the mounting slider 15 is squeezed and deformed by the limiting protrusion 412 in the mounting groove 41. The limiting slot 151 and the limiting protrusion 412 are engaged and fixed to lock the conversion component 4 and the vacuum cleaner 2, thereby locking the mounting housing 13 and the vacuum cleaner 2, and making the air inlet 11 of the mounting housing 13 connected to the vacuum cleaner 2. When the vacuum cleaner 2 needs to be disassembled, rotate the vacuum cleaner 2 counterclockwise. This causes the limiting protrusion 412 to be pressed and deformed by the inner wall of the limiting groove 151. The limiting protrusion 412 slides out of the limiting groove 151. Continuing to rotate, the mounting slider 15 slides along the mounting groove 41 and slides out of the mounting groove 41 through the notch 411. At this time, the vacuum cleaner 2 is separated from the mounting housing 13. Further, rotate the conversion component 4 counterclockwise. This causes the limiting protrusion 412 to be pressed and deformed by the inner wall of the limiting groove 151. The limiting protrusion 412 slides out of the limiting groove 151. Continuing to rotate, the mounting slider 15 slides along the mounting groove 41 and slides out of the mounting groove 41 through the notch 411, separating the conversion component 4 from the mounting housing 13. The user can confirm that the assembly is in place through tactile feedback (such as a "click" sound) or visual prompts (the arrow mark on the outside of the conversion component 4 is aligned with the locking mark on the main housing 1). It should be noted that, in this embodiment, the detachable installation structure between the vacuuming device 2 and the conversion component 4 is the same as the snap-on installation structure between the conversion component 4 and the main housing 1, and the detachable installation structure between the blower device 3 and the conversion component 4 is the same as the snap-on installation structure between the conversion component 4 and the main housing 1, which will not be described in detail here.

[0053] Furthermore, the vacuuming device 2 includes a vacuum pipe 21 and a filter assembly 22. The vacuum pipe 21 is installed at one end of the filter assembly 22, and the other end of the filter assembly 22 is detachably connected to the conversion component 4. The filter assembly 22 is used to filter impurities sucked in by the vacuum pipe 21. It should be noted that the vacuum pipe 21 and the filter assembly 22 can also be connected detachably by means of clips, magnetic attraction, etc., to facilitate the removal of the filter assembly 22 for cleaning impurities inside the filter assembly 22.

[0054] Furthermore, the filter assembly 22 includes a dust storage chamber 222 and a filter element 221. The filter element 221 is disposed at the outlet end of the dust storage chamber 222, and the outlet end of the dust storage chamber 222 is detachably connected to the conversion element 4. Specifically, the outlet end of the dust storage chamber 222 is provided with an installation slider 15, and the other end of the conversion component 4 is provided with an installation groove 41. When the dust collection component needs to be installed, the user aligns the dust storage chamber 222 with the conversion component 4 and rotates the dust storage chamber 222 circumferentially so that the installation slider 15 of the dust storage chamber 222 slides into the installation groove 41 of the conversion component 4 through the notch 411. When the installation slider 15 is located in the installation groove 41, the conversion component 4 and the dust storage chamber 222 are positioned relative to each other. When the conversion component 4 is rotated further, the side wall of the installation slider 15 is squeezed and deformed by the limiting protrusion 412 in the installation groove 41. The limiting slot 151 and the limiting protrusion 412 are engaged and fixed to lock the conversion component 4 and the dust storage chamber 222, thereby locking the installation housing 13 and the dust collection device 2 and making the air inlet 11 of the installation housing 13 connected to the dust collection device 2.

[0055] The filter assembly 22 further includes a baffle 223, which is installed at the inlet end of the dust storage chamber 222. The baffle 223 is provided with a mounting hole 2231, and the inlet end of the dust storage chamber 222 is provided with a plug-in part 2221. The baffle 223 is plugged into the dust storage chamber 222 through the plug-in part 2221 and the mounting hole 2231.

[0056] Specifically, the baffle 223 is a flexible silicone sheet. It should be noted that the filter element 221 can be installed in the dust collection chamber 222 via clips, magnets, or other means, facilitating the replacement and cleaning of the filter element 221.

[0057] Specifically, when the user uses the device to vacuum, external airflow enters through the suction pipe 21. The airflow pressure acts on the surface of the baffle 223, causing the baffle 223 to undergo elastic deformation and bend towards the dust storage chamber 222, thereby opening the channel between the dust storage chamber 222 and the suction pipe 21. Dust-laden air enters the dust storage chamber 222, and after being filtered by the filter element 221, the air is discharged from the outlet end of the dust storage chamber 222, while impurities remain in the dust storage chamber 222. When the vacuuming operation stops, the baffle 223 loses the effect of airflow pressure and returns to its original shape under its own elasticity, resealing the channel between the dust storage chamber 222 and the suction pipe 21, preventing impurities in the dust storage chamber 222 from flowing back into the suction pipe 21.

[0058] Furthermore, the vacuuming device 2 also includes a first brush head 23, which includes a mounting tube 231 and a brush head 232. The brush head 232 is mounted on the mounting tube 231, which has multiple fastening holes 233. The vacuuming tube 21 has multiple mounting buckles 211 along its axial direction. The first brush head 23 and the vacuuming tube 21 are fastened together by the fastening holes 233 and the mounting buckles 211. Specifically, when the mounting tube 231 slides along the axial direction of the vacuuming tube 21, the fastening holes 233 can fasten with the mounting buckles 211 at different positions. The fastening connection between the fastening holes 233 and the mounting buckles 211 allows for length adjustment between the first brush head 23 and the vacuuming tube 21 to accommodate cleaning needs in crevices of different depths. In addition, the first brush head 23 and the vacuuming tube 21 are detachably connected, allowing for the use of different materials or shapes of the brush head 232 to adapt to cleaning needs in different scenarios.

[0059] Furthermore, the blower device 3 includes an air blowing pipe 31 and a second brush head 32. One end of the air blowing pipe 31 is detachably connected to the conversion component 4, and the other end is detachably connected to the second brush head 32. Specifically, the second brush head 32 is detachably mounted on the air blowing pipe 31. When a user uses the blower device 3 to blow away dust and encounters stubborn dust and impurities, the second brush head 32 can be installed on the air blowing pipe 31 to clean the impurities. The second brush head 32 can be modified with different materials or shapes to adapt to the cleaning needs of different scenarios.

[0060] Furthermore, the conversion component 4 is provided with at least one mounting groove 41, which is spaced circumferentially along the port of the conversion component 4; the air inlet 11 and the air outlet 12 are provided with at least one mounting slider 15, which is spaced circumferentially along the inner side of the port of the air inlet 11 and the air outlet 12. By providing multiple mounting grooves 41 and mounting sliders 15, the conversion component 4 can achieve circumferential engagement with the main unit housing 1 during installation, further enhancing stability.

[0061] Furthermore, a protective mesh 111 is provided on the main unit housing 1 near the air inlet 11. In this embodiment, the protective mesh 111 has several mesh holes to intercept large particles such as hair and paper scraps from entering the interior of the main unit housing 1, and also to prevent the user from injuring their hands during operation.

[0062] Furthermore, the handle 14 is also provided with a charging port 19 for charging the battery inside the handle 14 during charging.

[0063] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model.
