Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaners, in particular to a blow-suction integrated vacuum cleaner with a switchable holding angle. Background Art

[0002] With the diversification and personalization of modern home environments, the versatility and convenience of cleaning tools have become important criteria for consumers to choose. Among many cleaning tools, vacuum cleaners are widely popular due to their efficient cleaning ability. With the increasing demand for a "subtraction" lifestyle among users, users hope that one device can meet multiple cleaning needs, reducing the cost of purchasing and maintaining multiple cleaning tools and the space for storing multiple cleaning tools.

[0003] Patent CN221266046U discloses a blow-suction integrated vacuum cleaner, which includes a gun head and a handle. A blower is built into the gun head. The gun head is provided with an air inlet and an air outlet. A dust cup is also provided on the air inlet. An ash inlet is provided on the dust cup. It also includes an air inlet cover and an air outlet cover. The air inlet cover is sleeved on the suction end of the blower and is in sealing cooperation with the outer wall of the suction end. The air inlet cover has a first extension part, and a first ventilation hole opposite to the suction end of the blower is provided on the first extension part. The air outlet cover is sleeved on the air outlet end of the blower and is in sealing cooperation with the outer wall of the air outlet end. The air outlet cover is provided with a second extension part, and a second ventilation hole opposite to the air outlet end of the blower is provided on the second extension part. By providing an air inlet cover and an air outlet cover to form an air cover, it is possible to prevent the suction and blowing from acting on the internal space of the gun head and the handle, thereby increasing the air pressure of suction and blowing, and also improving the energy utilization rate.

[0004] However, the handle and the gun head of the blow-suction integrated vacuum cleaner disclosed in Patent CN221266046U are rigidly connected, and the extension axis of the handle and the extension axis of the gun head are basically perpendicular, which makes the user's hand-held mode single. Generally speaking, during the cleaning operation, the gun head is inclined downward, and the comfort of holding the vertical handle is poor. Moreover, due to the variable cleaning space, when cleaning some special spaces, the single vertical mode of holding the handle may be limited by the angle, resulting in the inability to complete the cleaning operation in a comfortable holding state.

[0005] The utility model patent disclosed in Patent CN220256388U describes a vacuum cleaner with a rotatable handle. The vacuum cleaner realizes the quick switching between the two functions of suction and blowing through the handle provided at the lower end of the housing. The handle is designed to be inclined away from the air extraction port to adapt to ergonomics and improve the comfort during use. In addition, through the limit mechanism provided between the handle and the housing, the handle can rotate 180° forward and backward to adapt to different usage scenarios.

[0006] However, although the patent of CN220256388U provides an innovative handle rotation mechanism, in actual use, users may encounter more usage scenarios where the handle needs to be able to adjust at more angles to adapt to different cleaning requirements. For example, when cleaning high or low spaces, the fixed handle angle may not provide the best usage experience. In addition, although the existing handle rotation mechanism can rotate forward and backward, it cannot further adjust the included angle with the axial direction of the main body, which limits the flexibility and operation convenience of the vacuum cleaner at specific angles.

[0070] As Figure 1 shown, the present embodiment provides a blow - suction integrated vacuum cleaner with a switchable holding angle, including a main body 1 and a holding handle 2. The length of the main body 1 extends along a first extension direction, and a suction port c is provided at the first end A, and an air outlet d is provided at the opposite second end B. The first end A is used to connect a dust - collecting accessory M, and the second end B is used to connect a blowing accessory N.

[0071] As Figure 8 shown, on one side of the outer periphery of the main body 1, there is an outward - extending adapter portion 3. A transfer wheel 30 is provided at the end of the adapter portion 3, and a through - hole 31 is provided in the middle of the transfer wheel 30. The hole extension direction of the through - hole 31 is perpendicular to the first extension direction.

[0072] As Figure 1-8As shown, the length of the holding handle 2 extends along the second extension direction, and a connection groove 20 for the transfer wheel 30 to extend into is provided at the connection end of the holding handle 2.

[0073] As Figure 8 , 9 shown, the connection groove 20 includes a groove bottom wall 22 corresponding to the circumferential wall 33 of the transfer wheel 30 and two opposite groove side walls, a first groove side wall 23 and a second groove side wall 24. A rotating shaft 21 spanning the opposite groove walls is provided in the connection groove 20. The rotating shaft 21 passes through the shaft hole 31, and the holding handle 2 is rotatably connected to the main body 1 so that the angle between the first extension direction and the second extension direction is adjustable. The groove bottom wall 22 matches the circumferential wall 33 of the transfer wheel 30 to ensure smooth rotation and accurate positioning.

[0074] A multi-gear limiting mechanism is provided between the groove side wall and the wheel side wall 32 of the transfer wheel 30. The multi-gear limiting mechanism limits the relatively rotated holding handle 2 and the transfer wheel 30 at different angles, allowing the user to quickly adjust the handle to the most suitable angle according to the specific needs of the cleaning task, realizing holding at different angles, and increasing the flexibility and comfort of use.

[0075] As Figure 2 , 8 shown, the transfer part 3 includes a necking part 34 connected to the main body 1. The necking part 34 is used to increase the distance between the end face of the connection end of the holding handle 2 and the side face of the main body 1, facilitating installation and adjustment.

[0076] As Figure 1-9 shown, the end face of the connection end of the holding handle 2 is an arc-shaped end face S, and the arc contour of the arc-shaped end face S matches the arc contour of the transfer wheel 30, so that during the rotation process, the circumferential wall 33 and the holding handle 2 always form a continuous surface, which not only makes the appearance more tidy and beautiful, but also prevents dust and stains from entering between the rotating wheel and the connection groove 20.

[0077] The multi-gear limiting mechanism limits the holding handle 2 at least in four positions: a storage gear, a first tilt gear, a vertical gear, and a second tilt gear. As Figure 3 shown, in the storage gear, the holding handle 2 is placed horizontally and close to the side of the main body 1. The width of the entire vacuum cleaner is reduced.

[0078] As Figure 3-4 shown, when the transfer part 3 is not in the central position in the length direction of the main body 1, as Figure 3 shown, when the holding handle 2 turns to the relatively longer side, it is the first storage position, as Figure 4As shown, when rotated to the shorter side, it is in the second storage position. The storage gears can be one of the positions, or both storage positions can achieve positioning. Even when in the second storage position, the holding handle 2 extends beyond the length of the main body, and there is no interference from other accessories in the parallel position, and the extended part can still be used for holding.

[0079] As Figure 2 , 6 shown, in the first tilt gear and the second tilt gear, the holding handle 2 tilts relative to the main body 1 towards the first end A and the second end B respectively. As Figure 6 shown, when in the first tilt gear, the holding handle 2 tilts away from the blowing accessory N, and the first extension direction and the second extension direction form an obtuse angle, which is more suitable for the user to hold the handle 2 for blowing operation. As Figure 7 shown, when in the second tilt gear, the holding handle 2 tilts away from the dust suction accessory M, and the first extension direction and the second extension direction form an acute angle, which is more suitable for the user to hold the handle 2 for dust suction operation. More preferably, by setting more tilt gears, the user can switch the tilt angle between the holding handle 2 and the main body 1 according to the space state, so that the vacuum cleaner can adapt to more cleaning scenarios, such as high-angle cleaning, low-space cleaning, etc., thereby further improving the convenience of operation.

[0080] And as Figure 5 shown, in the vertical gear, the holding handle 2 is perpendicular to the main body 1. When the space is suitable, the user can switch the action direction of the functional component without rotating the holding handle 2, but only by switching the holding direction of his own hand.

[0081] As Figure 9 shown, the bottom wall 22 of the connecting groove 20 is provided with a concave arc-shaped guiding groove L, and the transfer wheel 30 is embedded in the arc-shaped guiding groove L. The arc-shaped guiding groove L plays a guiding and limiting role in the rotation of the transfer wheel 30. Even when a suitable assembly clearance is maintained between the side wall of the connecting groove 20 and the wheel side wall 32 of the transfer wheel 30, the holding handle 2 and the transfer part 3 can reduce the oscillation clearance through the restriction of the arc-shaped guiding groove L on the transfer wheel 30, improve the connection stability and the smoothness of rotation.

[0082] As Figure 10-11 shown, the main body 1 includes a housing 10, and a fixing piece 11 integrally formed with the transfer part 3 is fixedly arranged inside the housing 10. The fixing piece 11 abuts against the inside of the housing 10, and an avoidance hole is provided on the side part of the housing 10, and the necking part 34 extends out from the avoidance hole. This design enhances the connection structure between the transfer part 3 and the main body 1. Of course, in a more preferred solution, the transfer part 3 rotates on the fixing piece 11 in a manner of rotating around an axis perpendicular to the first extension direction, and the corresponding connection method can be found in the existing technology.

[0083] By introducing the handle folding mechanism described above in the existing rotation mechanism, the grip handle 2 can not only rotate horizontally but also be adjusted in angle vertically. This multi-dimensional adjustment ability enables the vacuum cleaner to better adapt to the user's usage habits and cleaning needs. Whether cleaning in narrow spaces or operating at high or low positions, users can achieve the best cleaning effect through simple handle adjustment.

[0084] As Figure 10 , 12 shown, the main body 1 includes a main body cavity V1, and a first electrical component is provided in the main body cavity V1. The grip handle 2 includes a handle cavity V2, and a second electrical component is provided in the handle cavity V2. The first electrical component and the second electrical component are connected by a connecting cable F. The multi-stage limiting mechanism is provided on the first side wall of the transfer wheel 30. The transfer wheel 30 is provided with a wire passing cavity g that is open to the second side wall. A wire passing channel t is provided from the fixing piece 11 through the necking part 34 to the wire passing cavity g. The bottom wall 22 of the groove protrudes on the convex edge of the arc-shaped guiding groove L and is provided with a wire passing hole. The connecting cable passes through the wire passing channel t from the main body cavity V1, passes through the wire passing cavity g, and enters the handle cavity V2 from the wire passing hole. Through the designed wire passing channel t and wire passing cavity g, the winding and damage of the cable are avoided, and the overall stability and durability are improved.

[0085] As Figure 9 , 12 , 13 shown, the multi-stage limiting mechanism includes an elastic gear piece 4 and a gear convex ring 5. Preferably, the elastic gear piece 4 is made of a nylon part. The transfer part 3 is made of other plastics with stronger rigidity, such as PP, etc. The separate design of this elastic gear piece 4 can make full use of the material characteristics to achieve the function.

[0086] Specifically, the elastic gear piece 4 is sleeved outside the rotating shaft 21 and fixed on one side wall of the groove. A plurality of elastic positioning protrusions r are provided on the outer ring wall of the elastic gear piece 4. The gear convex ring 5 is located on the wheel side wall 32 of the transfer wheel 30 opposite to the elastic gear piece 4, and the elastic gear piece 4 is embedded in the gear convex ring 5. A plurality of spaced positioning grooves y are provided on the inner wall of the gear locking convex ring.

[0087] In the first state, when the grip handle 2 is forced to rotate, the elastic positioning protrusion r is disengaged from the positioning groove y under the action of the circumferential force, and the elastic gear piece 4 rotates along the gear convex ring 5. In the second state, the elastic positioning protrusion r falls into the positioning groove y of the corresponding gear, and the rotation angle of the grip handle 2 is limited by the gear. The cooperative action of the elastic gear piece 4 and the gear convex ring 5 ensures the accuracy and repeatability of the handle rotation angle and avoids misoperation.

[0088] As Figure 13As shown, extension parts Q are respectively provided on both sides of the rotating shaft 21. A first groove h in the same direction as the rotating shaft 21 is provided at the end of the extension part Q. A ring-shaped positioning projection j is provided on the groove side wall. A second groove p is provided on the ring-shaped positioning projection j. A clamping projection w is provided on the inner ring wall of the elastic gear sheet 4. The clamping projection w is embedded in the first groove h, and the elastic positioning projection r is embedded in the second groove p. The elastic gear sheet 4 is detachably fixed on the groove side wall in this way, making the installation and replacement more convenient.

[0089] As Figure 11 As shown, the holding handle 2 includes a first half shell 201, a second half shell 202, and an arc-shaped clamping shell 203. The arc-shaped clamping shell 203 is fixed between the first half shell 201 and the second half shell 202. The first half shell 201 and the second half shell 202 extend beyond the arc-shaped clamping shell 203 to form a connecting groove 20. The outer surface of the arc-shaped clamping shell 203 is the groove bottom wall 22 of the connecting groove 20. Both sides of the arc-shaped clamping shell 203 are snap-connected to the first half shell 201 and / or the second half shell 202. A plurality of connecting ears 9 are provided below the arc-shaped clamping shell 203. Insertion holes are provided on the connecting ears 9. Insertion posts are provided on the first half shell 201 and the second half shell 202. The insertion posts are inserted into the insertion holes to further realize the positioning and fixing of the arc-shaped clamping shell 203.
