[0040] One embodiment of this utility model provides a handheld blowing and sucking device, see reference. Figures 1-11 ,include:

[0041] 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.

[0042] A dust collection device 2 is detachably installed on the air inlet 11, and the dust collection device 2 is used to perform a dust collection function.

[0043] The blower 3 is detachably installed at the air outlet 12 and is used to perform the dust blowing function.

[0044] This application solves the problems of traditional cleaning equipment being single-function, cumbersome to operate, and lacking convenience. The main unit housing 1 of this application is provided with an air inlet 11 and an air outlet 12 at both ends. The vacuuming device 2 and the blowing device 3 are detachably and independently installed at the corresponding ports. Users can switch between vacuuming and blowing modes by quick disassembly and assembly according to their cleaning needs. This allows for flexible switching between vacuuming and blowing functions without replacing the entire device, reducing purchase costs and storage space occupation. 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, and 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. When the vacuum cleaner 2 is detachably installed at the air inlet 11, the device can perform a vacuuming function. When the blower 3 is detachably installed at the air outlet 12, the device can perform a blowing function. The vacuuming or blowing mode can be switched quickly through disassembly and assembly, eliminating the need to carry or use multiple devices for cleaning, thus reducing purchase costs. Furthermore, when the user does not need to use the device, the vacuum cleaner 2 and blower 3 can be detached and stored together with the main housing 1, reducing storage space occupation and facilitating portability. The device can also be used as a fan when not in use for cleaning.

[0045] It should be noted that in other embodiments, the handle 14 and the mounting housing 13 can also be detachably installed, which facilitates storage and carrying, and improves the portability of the product.

[0046] 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 and directional airflow at the air outlet. 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 18 and a control switch 17 are also provided on the surface of the mounting housing 13. The wind speed adjustment switch 18 adjusts the airflow of the device, and the control switch 17 controls the start and stop of the device. Specifically, the wind speed adjustment switch 18 and the control switch 17 are electrically connected to the control circuit board inside the handle 14. The wind speed adjustment switch 18 and the control switch 17 are arranged opposite each other, with the wind speed adjustment switch 18 located on the front side of the mounting housing 13 and the control switch 17 located on the rear side. This arrangement allows the user to easily touch the wind speed adjustment switch 18 with their right index finger and simultaneously touch the control switch 17 with their right thumb, without significantly moving their wrist, thus improving the user experience and facilitating operation. Furthermore, a display screen 19 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.

[0047] Specifically, when a user needs to use the device for vacuuming, the vacuum cleaner 2 should first be installed at the air inlet 11. Then, the user should press the control switch 17 on the back of the housing 13 with their right thumb to start the device. At this time, the control circuit board receives the signal and activates the motor. The display screen 19 lights up simultaneously and displays the default fan speed level and battery status. The user can press the fan speed adjustment switch 18 to adjust the air volume step by step (e.g., low, medium, and high). During the adjustment, the display screen 19 updates the current fan speed value in real time. When switching to blowing operation, the user should press the control switch 17 again to turn off the device, then remove the vacuum cleaner 2 from the air inlet 11 and install the blower 3 at the air outlet 12. Then, the user should press the control switch 17 again to start the device and repeat the above operation. After all the work is completed, the user should press the control switch 17 to turn off the device, remove the blower 3 from the air outlet 12, and store the main housing 1, the blower 3, and the vacuum cleaner 2.

[0048] Furthermore, the vacuuming device 2 includes a suction component 22 and a first conversion component 21. One end of the first conversion component 21 is detachably installed with the suction component 22, and the other end is detachably installed with the air inlet 11. Specifically, the surface of the first conversion component 21 is provided with an indicator arrow to facilitate quick identification of the installation direction by the user during installation. The first conversion component 21 is also provided with an unlock mark and a lock mark. The suction component 22 is provided with an indicator arrow to facilitate quick visual judgment of the assembly status of the interface by the user. When the suction component 22 is locked in place, the arrow mark on the suction component 22 is aligned with the lock mark; when the suction component 22 is disassembled, the arrow mark on the suction component 22 is rotated to align with the unlock mark. It should be noted that the detachable installation method can be a snap-fit ​​connection, a magnetic connection, etc., and in this embodiment, a snap-fit ​​connection is preferred.

[0049] Furthermore, a first assembly part 211 is provided at one end of the first conversion component 21, and a second assembly part 15 is provided at the air inlet 11 of the main unit housing 1. The first assembly part 211 and the second assembly part 15 cooperate to lock the first conversion component 21 and the main unit housing 1.

[0050] The other end of the first conversion component 21 is provided with a third assembly part 212, and the air intake component 22 is provided with a fourth assembly part 224. The third assembly part 212 and the fourth assembly part 224 cooperate to lock the first conversion component 21 and the air intake component 22.

[0051] In this embodiment, the first assembly part 211 includes a mounting groove 2111 circumferentially opened along the port of the first conversion member 21, and the second assembly part 15 includes a mounting slider 151 circumferentially arranged along the inner side of the air inlet 11 of the main unit housing 1. The mounting slider 151 is slidably connected to the mounting groove 2111, and the mounting groove 2111 has a notch 2112 for the mounting slider 151 to slide into.

[0052] Furthermore, a limiting groove 152 is provided at the end of the mounting slider 151, and a limiting protrusion 2113 that is adapted to and engages with the limiting groove 152 is provided in the mounting groove 2111. Specifically, when the first adapter 21 needs to be installed to the air inlet 11, the user aligns the first adapter 21 with the air inlet 11 of the main unit housing 1 and rotates the first adapter 21 circumferentially, so that the mounting slider 151 slides into the mounting groove 2111 through the notch 2112. When the mounting slider 151 slides to the position of the limiting protrusion 2113, the user continues to rotate, and the limiting groove 152 at the end of the mounting slider 151 engages with the limiting protrusion 2113 in the mounting groove 2111, thereby locking the first adapter 21 to the main unit housing 1. 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 first adapter 21 is aligned with the locking mark on the main unit housing 1). During disassembly, the first conversion component 21 is rotated in the reverse direction, and the limiting protrusion 2113 is squeezed out of the limiting slot 152. The mounting slider 151 slides out along the notch 2112, achieving one-click quick separation. In this embodiment, the structure of the third assembly part 212 is the same as that of the first assembly part 211, and the structure of the fourth assembly part 224 is the same as that of the third assembly part 212. Their working process is also the same as that between the first assembly part 211 and the second assembly part 15, and will not be described in detail here.

[0053] Further, the suction assembly 22 includes a suction pipe 222 and a filter assembly 221. The suction pipe 222 is installed at one end of the filter assembly 221, and the other end of the filter assembly 221 is detachably installed on the conversion component. The filter assembly 221 is used to filter impurities sucked in by the suction pipe 222. In this embodiment, the filter assembly 221 includes a dust storage chamber 2212, a filter element 2211, and a baffle 2213. The filter element 2211 is disposed at the outlet end of the dust storage chamber 2212, and one end of the baffle 2213 is fixed to the inlet end of the dust storage chamber 2212, used to close or open the channel between the dust storage chamber 2212 and the suction pipe 222. Specifically, the baffle 2213 is an elastic silicone sheet with a mounting hole. A plug-in end is provided on the inner side of the inlet end of the dust storage chamber 2212, and the baffle 2213 is installed by interference fit between the plug-in end and the mounting hole. It should be noted that the filter element 2211 can be installed in the dust storage chamber 2212 by means of snap-fit, magnetic attraction, etc., which makes it easy to replace and clean the filter element 2211.

[0054] Specifically, when the user uses the device to vacuum, external airflow enters through the suction pipe 222. The airflow pressure acts on the surface of the baffle 2213, causing the baffle 2213 to undergo elastic deformation and bend towards the dust storage chamber 2212, thereby opening the channel between the dust storage chamber 2212 and the suction pipe 222. Dust-laden air enters the dust storage chamber 2212, and after being filtered by the filter element 2211, the air is discharged from the outlet end of the dust storage chamber 2212, while impurities remain inside the dust storage chamber 2212. When the vacuuming operation stops, the baffle 2213 loses the effect of airflow pressure and returns to its original shape under its own elasticity, resealing the channel between the dust storage chamber 2212 and the suction pipe 222, preventing impurities in the dust storage chamber 2212 from flowing back into the suction pipe 222.

[0055] Furthermore, a first brush head 23 is provided at the end of the suction pipe 222 away from the main housing 1. In this embodiment, the first brush head 23 includes a mounting tube 231 and a brush head 232. The mounting tube 231 has multiple fastening holes 233, and the suction pipe 222 has multiple mounting buckles 223 along its axial direction. When the mounting tube 231 slides along the axial direction of the suction pipe 222, the fastening holes 233 can be fastened with the mounting buckles 223 at different positions. The fastening connection between the fastening holes 233 and the mounting buckles 223 enables the length adjustment between the first brush head 23 and the suction pipe 222 to adapt to the cleaning needs of crevices of different depths. In addition, the first brush head 23 and the suction pipe 222 are detachably connected, and different materials or shapes of brush heads 232 can be changed to adapt to the cleaning needs of different scenarios.

[0056] Furthermore, the blower device 3 includes an air blowing pipe 32 and a second conversion component 31. One end of the second conversion component 31 is detachably installed with the air blowing pipe 32, and the other end is detachably installed with the air outlet 12. In this embodiment, the second conversion component 31 has the same structure as the aforementioned first conversion component 21, and its surface is also provided with an indicator arrow, an unlock mark, and a lock mark, but the arrow direction is opposite to that of the first conversion component 21 to adapt to the airflow direction of the blower mode. Further details are omitted here.

[0057] Furthermore, a fifth assembly part 311 is provided at one end of the second conversion component 31, and a sixth assembly part 16 is provided at the air outlet 12 of the main unit housing 1. The fifth assembly part 311 and the sixth assembly part 16 cooperate to lock the second conversion component 31 and the main unit housing 1.

[0058] The other end of the second conversion component 31 is provided with a seventh assembly part 312, and the air blowing pipe 32 is provided with an eighth assembly part 321. The seventh assembly part 312 and the eighth assembly part 321 cooperate to lock the second conversion component 31 and the air blowing pipe 32. In this embodiment, the structure of the second conversion component 31 is the same as that of the first conversion component 21. The sixth assembly part 16 provided at the air outlet 12 of the main housing 1 has the same structure as the second assembly part 15 provided at the air inlet 11 of the main housing 1. The eighth assembly part 321 provided on the air blowing pipe 32 has the same structure as the fourth assembly part 224 provided on the air intake component 22. The installation process between the second conversion component 31 and the main housing 1 and the air blowing pipe 32 is also the same as the installation process between the first conversion component 21 and the main housing 1 and the air intake component 22. Therefore, it will not be described in detail here.

[0059] Furthermore, a second brush head 33 is provided at the end of the air blowing pipe 32 away from the main housing 1. Specifically, the second brush head 33 is detachably mounted on the air blowing pipe 32. When the user uses the blower 3 to blow away dust and encounters stubborn dust and impurities, the second brush head 33 can be installed on the air blowing pipe 32 to clean the impurities. The second brush head 33 can be modified with different materials or shapes to adapt to the cleaning needs of different scenarios.

[0060] 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.

[0061] Furthermore, the handle 14 is also provided with a charging port 141 for charging the battery inside the handle 14 during charging.

[0062] 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.
