[0050] Example

[0051] The embodiment of the present application provides a handheld blower-suction machine, as shown in Figures 1 to 8, comprising: an air duct 1, a fan compartment 3 and a fan 33;

[0052] One end of the air duct 1 is provided with an air outlet 11 communicating with the outside world, and the other end of the air duct 1 is respectively connected to the air outlet 11 and one end of the fan compartment 3; the end of the fan compartment 3 away from the air duct 1 is provided with a vent 311;

[0053] The fan 33 can be relatively movably arranged in the fan compartment 3 to change the air outlet direction of the fan 33 relative to the air duct 1 to achieve switching between the suction mode and the blowing mode.

[0054] The air duct 1 is used for air circulation. In different functional modes of the handheld blower-suction machine, the air outlet direction of the fan 33 relative to the air duct 1 is different, and the specific direction of the air flow in the air duct 1 is also different. When the air outlet direction of the fan 33 is toward the air duct 1, the air flow generated by the fan 33 flows from the fan compartment 3 to the air outlet 11, and the handheld blower-suction machine is in the blowing mode; when the air outlet direction of the fan 33 is opposite to the air duct 1, the air flow generated by the fan 33 flows from the fan compartment 3 to the air outlet 311, and the handheld blower-suction machine is in the suction mode.

[0055] There are many ways to change the air outlet direction of the fan 33 relative to the air duct 1.

[0056] For example, the fan 33 may be driven to rotate by a motor. Of course, there is no limitation on the specific method of changing the air outlet direction of the fan 33 relative to the air duct 1 .

[0057] Furthermore, as shown in FIG1 , FIG6 and FIG7 , the fan compartment 3 includes: an inner compartment 32 and an outer compartment 31 , one end of the outer compartment 31 is connected to the air duct 1 , and an end of the outer compartment 31 away from the air duct 1 is provided with a vent 311 communicating with the outside world;

[0058] The fan 33 is placed in the inner cabin 32, and the inner cabin 32 is movably arranged in the outer cabin 31. The inner cabin 32 is transmission-connected to the switching knob 4, and the switching knob 4 extends out of the outer cabin 31 at one end away from the inner cabin 32. By rotating the switching knob 4, the inner cabin 32 is driven to rotate relative to the outer cabin 31 to change the air outlet direction of the fan 33 relative to the air duct 1.

[0059] Specifically, in some embodiments of the present application, when the blowing direction of the fan 33 is toward the air outlet 11, the handheld blower-suction machine is in the blowing mode, and the airflow passes through the air duct 1 from the inside to the outside;

[0060] When the blowing direction of the fan 33 is toward the vent 311 , the handheld blower-vacuum machine is in the suction mode, and the air flows through the air duct 1 from outside to inside.

[0061] Specifically, in some embodiments of the present application, the vents 311 include at least two, and all the vents 311 are evenly distributed along the circumference of the outer wall of the outer cabin 31 away from the air duct, which helps to achieve uniform and smooth flow of gas, and to a certain extent can avoid local poor ventilation, thereby optimizing the overall ventilation effect of the fan compartment 3; by evenly distributing the vents 311, the local pressure difference formed on the outer wall of the outer cabin 31 can also be reduced, reducing the impact of wind pressure on the structure, which is beneficial to the stability and safety of the structure.

[0062] Furthermore, as shown in FIG2 to FIG4, FIG6 and FIG7, the outer chamber 31 is provided with a through hole 312, and the end of the switch knob 4 away from the inner chamber 32 passes through the through hole 312 and extends out of the outer chamber 31;

[0063] A stepped annular boss 51 is provided on the outer wall of the outer chamber 31 in the area corresponding to the through hole 312 , and a strip-shaped protrusion 52 is provided on the outer wall of the switch knob 4 ; the rotation range of the switch knob 4 is limited by the boss 51 locking the protrusion 52 .

[0064] Through the design of the boss 51 and the bump 52, the rotation range of the switch knob 4 is limited. When the bump 52 is connected to the boss 51, the boss 51 acts as a stop to prevent the switch knob 4 from continuing to rotate. On the one hand, it can prevent the switch knob 4 from being damaged due to excessive rotation to a certain extent. On the other hand, when the switch knob 4 is rotated to the above-mentioned stop position, it is one of the suction mode or the blowing mode, which means that the mode switching is completed, which is convenient for users to use, optimizes the user experience, makes the rotation process of the switch knob 4 more stable, and improves the accuracy and comfort of the operation.

[0065] Specifically, in some embodiments of the present application, the rotatable angle of the switch knob 4 is 0 degrees to 200 degrees. Of course, there is no limitation on the rotatable angle.

[0066] Preferably, in some embodiments of the present application, the switching knob 4 can be rotated to an angle of 0 to 180 degrees, and can be locked when rotated to 0 or 180 degrees. At this time, the centers of the air duct 1, the collection bin 2, the fan 33, and the fan bin 3 are coaxially arranged, and the handheld blower-suction machine is in the suction mode or the blowing mode, which helps to efficiently transmit the airflow and reduce energy loss.

[0067] For example, the switch knob 4 can be set to the blowing mode by rotating 180 degrees from the initial position. The centers of the air duct 1, the collection bin 2, the blowing surface of the fan 33, and the fan bin 3 are coaxially arranged. At this time, the blowing surface of the fan 33 faces the air outlet 11 of the air duct 1.

[0068] Similarly, when the handheld blower-vacuum machine is in the blowing mode, it can be switched to the suction mode by rotating it 180 degrees in the opposite direction.

[0069] Furthermore, a rotating shaft (not shown in the figure) is provided at one end of the inner cabin 32 away from the switching knob 4, and the inner wall of the outer cabin 31 is recessed downward to form a rotating groove (not shown in the figure) adapted to the rotating shaft. The rotating shaft is rotatably connected to the rotating groove so that the positional relationship between the inner cabin and the outer cabin is relatively stable and not prone to displacement during rotation.

[0070] Furthermore, as shown in FIG7 , a damping sealing ring 322 is also provided in the handheld blower-suction machine;

[0071] The outer wall of the inner chamber 32 is provided with a sealing groove 321 that matches the shape of the damping sealing ring 322 , and the damping sealing ring 322 is provided on the sealing groove 321 ;

[0072] The inner compartment 32 is connected to the outer compartment 31 in a damping rotation manner via a damping sealing ring 322 .

[0073] The provision of the sealing groove 321 facilitates the assembly of the damping sealing ring 322, helps to improve assembly efficiency, and also helps to avoid leakage problems caused by loosening or displacement of the damping sealing ring 322, thereby improving the stability of the sealing effect; the provision of the damping sealing ring 322 and the sealing groove 321 can, to a certain extent, prevent the airflow in the fan compartment 3 from overflowing from the gap between the inner compartment 32 and the outer compartment 31, thereby optimizing the gas flow effect, and thereby optimizing the functional effects of the suction mode and the blowing mode.

[0074] Finally, when in the suction mode or the blowing mode, the damping seal ring 322 contacts the inner wall of the outer cabin 31, and there is friction, which can prevent any movement between the inner cabin 32 and the outer cabin 31, and play a damping effect, so that the positions of the fan 33, the inner cabin 32, and the outer cabin 31 are relatively fixed.

[0075] Furthermore, as shown in FIG7 , the inner wall of the inner cabin 32 is provided with a support member 323 , and the support member 323 includes one or at least two support members 323 ; the shape of the support member 323 matches the shape of the fan 33 ,

[0076] The fan 33 is mounted on the support member 323 to achieve connection between the fan 33 and the inner cabin 32 .

[0077] The support member 323 provided on the inner wall of the inner chamber 32 can simplify the connection process between the fan 33 and the inner chamber 32 and provide relatively stable support for the fan 33. The shape of the support member 323 matches the shape of the fan 33, which helps to stably install the fan 33 in the inner chamber 32.

[0078] The support member 323 can also avoid direct contact between the fan 33 and the inner compartment 32 , which is beneficial to the flow of air, enhances the heat dissipation effect, and prolongs the service life of the fan 33 .

[0079] Furthermore, as shown in FIG1 to FIG5, the handheld blower-suction machine is further provided with a collection bin 2; the collection bin 2 is used to store the sucked-in dust, dirt, debris or garbage;

[0080] The collection chamber 2 is located between the air duct 1 and the fan chamber 3, and the air duct 1, the collection chamber 2, and the fan chamber 3 are connected in sequence;

[0081] One end of the air duct 1 away from the air outlet 11 extends into the collection bin 2 , and one end of the collection bin 2 away from the air duct 1 is connected to the fan bin 3 . A filter 21 is provided on one side of the collection bin 2 close to the fan bin 3 .

[0082] After the airflow passes through the air duct 1, the dust and garbage are retained in the collection bin 2;

[0083] The filter 21 can effectively intercept dust, dirt, debris and garbage in the collection bin 2, prevent dust, dirt, debris and garbage from entering the fan bin 3, help keep the inside of the fan bin 3 clean, reduce the possibility of wear and failure of the fan 33 due to dust, and extend the service life of the fan 33.

[0084] Furthermore, the cross-sectional shape of the fan cassette 3 includes a circle;

[0085] Specifically, in some embodiments of the present application, the cross-sectional shape of the inner cabin 32 and / or the outer cabin 31 includes a circle, and the shape of the portion of the inner cabin 32 and / or the outer cabin 31 corresponding to the portion accommodating the inner cabin 32 is spherical. The spherical shape design and the circular cross-sectional shape can reduce the rotational resistance between the inner cabin 32 and the outer cabin 31, making the rotation between the inner cabin 32 and the outer cabin 31 more convenient;

[0086] The spherical design is also conducive to improving space utilization, and the structure is relatively compact, so that the fan 33 can be as large as possible within a limited space, which helps to enhance the suction or blowing effect.

[0087] The inner diameter of the air duct 1 is not larger than the inner diameter of the collection chamber 2;

[0088] On the one hand, the larger volume of the collection bin 2 helps to obtain a larger storage space. On the other hand, when in the suction mode, after dust, garbage, etc. enter the collection bin 2 from the air duct 1, the cavity becomes larger, the air flow rate slows down, the pressure increases, and the carrying capacity is weakened, and the dust and garbage fall directly into the collection bin 2.

[0089] The inner diameter of the air duct 1 gradually narrows from one end close to the collection bin 2 to the end where the air outlet 11 is provided; when in the blowing mode, the design of the air duct 1 gradually narrowing from one end close to the collection bin 2 can speed up the airflow speed. When the airflow passes through the narrowed part, the flow rate will be accelerated due to the smaller cross-sectional area, thereby increasing the flow speed of the airflow to obtain a better cleaning effect.

[0090] Furthermore, as shown in FIG5 , one of the ends of the air duct 1 close to the collecting bin 2 and the end of the collecting bin 2 close to the air duct 1 is provided with an annular protrusion 61, and the other one is provided with an annular groove 62;

[0091] And / or one of the ends of the collecting bin 2 close to the fan bin 3 and the end of the fan bin 3 close to the collecting bin 2 is provided with an annular protrusion 61, and the other one is provided with an annular groove 62;

[0092] By embedding the protrusion 61 in the groove 62 , the detachable connection between the air duct 1 and the collection bin 2 and the detachable connection between the collection bin 2 and the fan bin 3 are achieved.

[0093] The detachable connection between the air duct 1 and the collection bin 2, and the detachable connection between the collection bin 2 and the fan bin 3 facilitate daily maintenance and cleaning. The air duct 1, the collection bin 2 and the fan bin 3 can be disassembled and assembled, which is convenient for regular maintenance and cleaning; by embedding the protrusion 61 in the groove 62, the positions of the air duct 1, the collection bin 2 and the fan bin 3 can be relatively fixed, which plays the role of pre-connection or auxiliary connection, thereby improving the stability of the entire device.

[0094] Furthermore, as shown in FIG1 to FIG4 and FIG8, the handheld blower-suction machine is also provided with a handle 7.

[0095] The handle 7 is connected to the end of the fan compartment 3 away from the air duct 1. The handle 7 is provided with a gripping portion 71 that fits the shape of the hand. The inner wall of the gripping portion 71 is provided with anti-slip lines 711.

[0096] The handle 7 design makes the handheld blower-vacuum machine easier to carry and operate, and the user can move and use the handheld blower-vacuum machine more easily, thereby improving the portability and flexibility of the handheld blower-vacuum machine.

[0097] The gripping portion 71 fits the shape of the hand, taking into account the actual needs and operating habits of the user, conforming to ergonomics, and can provide a more comfortable gripping experience and reduce the pressure on the user when gripping; anti-slip grooves 711 are provided to effectively increase the friction of the gripping portion 71, prevent the hand from slipping during use, improve operational safety, and reduce accidental risks.

[0098] Furthermore, as shown in Figures 1 to 4 and 8, the handheld blower-suction machine is further provided with a power supply 8, and a connector 91 is provided on one of the end of the handle 7 away from the blower compartment 3 and the outer wall of the power supply 8, and a connecting seat 92 is provided on the other of the two.

[0099] The detachable connection between the handle 7 and the power supply 8 is achieved by embedding the connecting piece 91 in the connecting seat 92.

[0100] The handle 7 and the power supply 8 are detachably connected by embedding the connector 91 into the connecting seat 92. The handle 7 and the power supply 8 are designed to be separate, which is convenient for carrying, storage and maintenance. The user can disassemble or connect the handle 7 and the power supply 8 at any time as needed, which enhances the flexibility of use.

[0101] Furthermore, as shown in Figures 1, 3 and 8, the handheld blower-suction machine is also provided with a key switch 72 electrically connected to the fan 33 and the power supply 8 respectively; the key switch 72 is located on the outer wall of the handle 7 away from the gripping portion 71.

[0102] The button switch 72 is arranged on the outer wall of the handle 7 away from the grip portion 71. The user can easily touch and control the switch without changing the position of the hand grip, which is convenient for the user's actual use.

[0103] Furthermore, as shown in Figures 1, 5, 6 and 7, the outer wall of the outer cabin 31 is evenly distributed with reinforcing rib structures 313, which can enhance the structural strength of the outer cabin 31 and enable it to better withstand external impacts and pressures. The design of the reinforcing rib structure 313 can also enhance the aesthetic appearance of the outer cabin 31 to a certain extent.

[0104] The embodiments of the present application have at least the following beneficial effects:

[0105] The fan compartment 3 of the present application includes: an outer compartment 31 and an inner compartment 32. A fan 33 is provided in the inner compartment 32. The inner compartment 32 can be movably placed in the outer compartment 31. The inner compartment 32 is transmission-connected to a switching knob 4. By rotating the switching knob 4, the suction mode and the blowing mode are switched. The handheld blower-suction machine is easy to use, and has both the suction mode and the blowing mode.

[0106] A boss 51 and a bump 52 are provided to limit the rotation range of the switch knob 4, acting as a stop after the mode switch is completed, facilitating user use. A damping seal ring 322 and a sealing groove 321 are provided to provide a damping effect when in the suction mode or the blowing mode. The cross-sectional shape of the inner chamber 32 and / or the outer chamber 31 includes a circular shape, which can reduce rotational resistance between the inner chamber 32 and the outer chamber 31. The inner diameter of the air duct 1 is no larger than the inner diameter of the collection chamber 2, and the inner diameter of the air duct 1 gradually narrows from the end near the collection chamber 2 to the end provided with the air outlet 11, so as to achieve a better cleaning effect.
