Background technique

With the development of lithium battery technology, rechargeable vacuum cleaners have become popular. The more popular rechargeable vacuum cleaners include a main unit, a connecting tube and a ground brush. The main unit is provided with an electric fan that generates a negative pressure, and a dust bucket that accommodates dust. Vacuum cleaners, especially rechargeable vacuum cleaners with a host located above the rigid connecting tube, are popular. However, the vacuum cleaner has a relatively high host position, so that the center of gravity of the entire product is high and it is easy to dump when placed vertically.

Suzhou Weikes Electric Co., Ltd. applied for a charging stand, its application number is 201721514417.5. After the vacuum is completed, the user needs to split the vacuum cleaner main unit and connecting pipe, put the main unit on the charging stand to lower the center of gravity, and then The connecting tube is inserted into the charging stand. Since it is necessary to bend over and assemble the vacuum cleaner before each cleaning, it is inconvenient to bend down to store the vacuum cleaner after cleaning.

detailed description

The invention will now be described in further detail with reference to the drawings and embodiments.

1 to 3, the support frame 10 shown in the figure is in an unfolded state, including a first frame connected by the

side frames

22, 23 and the bottom frame 24; and the

side frames

30, 31 and the bottom frame 32 are connected. a second frame, and a platform 21 hinged to the top ends of the first frame and the second frame, further comprising a two-layer connecting curtain and a load-bearing mechanism 51 for limiting the first frame and the second frame The angle in the unfolded state; the load-bearing mechanism is used to mount the vacuum cleaner to the main unit.

Between the first frame and the second frame, two layers of connecting curtains, namely a first curtain 52, and a second curtain 53, each having a U-shaped opening, the curtain of the lower layer as an example, the second frame is provided A cross bar 531 is disposed between the two side frames, and the side frame of the first frame is provided with two stoppers 532 which are oppositely convex. The curtain 53 is connected to the cross bar 531 and the two blocks 532. When the support frame is in the unfolded state, due to the gravity of the frame itself, the connecting

curtains

52, 53 can be tightened between the first frame and the second frame, preventing the angle between the first frame and the second frame from continuing to expand, The support frame 10 can be stably stood and provides reliable support for the vacuum cleaner. After the connection curtain is stretched, various vacuum cleaner accessories can be placed thereon, and other daily articles such as books can be placed, which further increase the weight of the support frame, so that the support frame stands more stable. In the unfolded state, the second frame is substantially in the vertical direction, and the first frame is opened to a certain angle so that the support frame can stably stand on the indoor floor.

It should be noted that the tops of the first frame and the second frame may also be connected in series on one pole, thereby eliminating the platform at the top of the support frame. If a platform is provided, the connection curtain can also be replaced with a rigid connection structure, which is hingedly connected to the first frame and the second frame, respectively. In the unfolded state, the rigid connection mechanism is fixedly coupled to the first frame and the second frame, respectively. When accommodation is required, the rigid connecting mechanism is released from the first frame and the second frame, the rigid connecting mechanism is parallel to the first frame or the second frame, and then the first frame and the second frame are laminated into a flat plate shape.

Preferably, the length of the first frame is greater than the length of the second frame, and in the unfolded state, the angle between the first frame and the second frame is between 15 and 30 degrees. In this way, the vacuum cleaner can achieve a stable balance in a backward tilting posture, and can reduce the footprint of the bottom of the support frame to avoid occupying excessive indoor space.

The first frame can also be folded into a flat shape relative to the second frame to facilitate packaging transportation. The change in the relative position of the first frame and the second frame enables the support frame of the present invention to be switched between the stowed state and the unfolded state.

The support frame of the present invention can be used for a rechargeable vacuum cleaner supporting a high center of gravity. The vacuum cleaner includes at least a main body, a rigid connecting pipe and a ground brush, and can also include a main body clamping mechanism.

The load-bearing mechanism is used for receiving the main body of the rechargeable vacuum cleaner. In this embodiment, the load-bearing mechanism is a nest-shaped curtain 51 located between the first frame and the second frame, and the curtain 51 and the side frame of the first frame are convex. The

stoppers

25, 26, the crossbar 511 between the side frames of the second frame, and the top platform 21 are fixedly connected, respectively, for receiving the main body of the rechargeable vacuum cleaner. The upper surface (bearing surface) of the curtain 51 is located between the first frame and the second frame, contacts the main body of the cleaner and supports the main body of the cleaner. The two sides of the curtain 51 also contact the main body of the cleaner, together with the two sides of the first frame, prevent the main body of the cleaner from moving sideways.

Load-bearing mechanisms can also be used with foldable rigid materials. When it is necessary to store, the rigid load-bearing mechanism is folded. In the unfolded state, the rigid load-bearing mechanism is deployed and then assembled to the support frame.

The side frame of the first frame may be provided with a circular arc and is recessed toward the second frame, so that when the user puts the vacuum cleaner main body into the load-bearing mechanism, the side frame of the first frame does not touch the user's arm.

The

stoppers

25 and 26 are oppositely disposed, and the limiting opening 54 is formed in the middle. The width of the limiting opening is preferably greater than 35 mm and less than 75 mm, because the outer diameter of the connecting pipe is generally about 35 mm, and the connecting pipe is connected with the main body of the vacuum cleaner. The width of the plastic part (main suction opening) is generally greater than 75 mm. When the user stores the host 20 on the support frame, the vacuum cleaner main unit 20 can be moved up over the limit opening to allow the connecting tube to pass through the limit opening. Then, the user releases the vacuum cleaner main unit 20 onto the curtain 51, and the connecting tube The downward movement causes the limit opening to be opposite to the main suction port. At this time, if the vacuum cleaner main body is subjected to an outward thrust, the vacuum cleaner main body swings outward, and the limit opening collides with the main suction port, thereby restricting the vacuum cleaner main body to the inside of the support frame.

Since the curtain 51 is in the shape of a nest, and the upper surface (bearing surface) is located between the first frame and the second frame, when the vacuum cleaner main body is placed on the curtain 51, the two sides of the vacuum cleaner main body are not only located on the two curtains 51. Between the sides, also between the two side frames of the first frame, so it does not slip to the outside of the support frame.

Referring to FIG. 4 to FIG. 5, the load-bearing mechanism can also be adopted as a flexible material such as a curtain, and is fixed at an upper portion of the front of the first frame, and has a width larger than a width between the two sides of the first frame, so that the curtain can be The main frame is recessed from the first frame to the second frame for accommodating the charging vacuum cleaner. And the load bearing surface combined with the vacuum cleaner main body is located between the first frame and the second frame. In order to avoid touching the user's arm, an arc may be formed on the side frame of the first frame, and the arc is recessed toward the second frame. The opening size of the arc is smaller than the outer shape of the vacuum cleaner main body, and the side frame of the first frame can block the vacuum cleaner main body. It is also ensured that at least a portion of the load bearing surface is located between the side frame of the first frame and the second frame.

The load-bearing mechanism can also be made into a relatively flat shape by using an elastic curtain, but can be automatically recessed toward the second frame after being subjected to the pressure of the vacuum cleaner main body.

The load-bearing mechanism may also be in the form of a grid connected to the side frames of the first frame.

Before use, the user relatively opens the first frame and the second frame of the support frame. Because of the hinge of the upper end platform and the limit of the lower end of the screen, the support frame can maintain a wide shape of the lower end relative to the upper end, and stably stand On the indoor floor.

After the user completes the vacuuming work, the connection state of the main body and the connecting pipe and the ground brush can be maintained without disassembling the vacuum cleaner, and the vacuum cleaner main body is placed on the support frame 10 together with the connecting pipe and the ground brush. Specifically, the vacuum cleaner main body is placed in a nest-shaped load-bearing mechanism, and the vacuum cleaner main body is reliably restrained in the front, rear, left and right directions, and is difficult to dump. The bottom frame 24 of the first frame interferes with the ground brush of the cleaner to prevent the ground brush from sliding forward.

Preferably, the lower surface of the bottom frame of the first frame is no more than 6.5 cm from the ground. Because the height of the brush is known to be less than 6.5 cm.

If the user takes the vacuum cleaner, simply lift the main unit slightly upwards to allow the main unit and the main suction port to pass over the limit opening, and smoothly remove the vacuum cleaner from the support frame. Therefore, the present invention facilitates the access and storage of the vacuum cleaner.

As shown in Fig. 6, the load-bearing mechanism may also be a rigid support plate 56 fixed on the first frame, such as a metal plate or a wooden board. The vacuum cleaner assembly includes at least a vacuum cleaner main body 57, a clamping mechanism 58, a rigid connecting pipe, and a ground brush. . When the support frame is in the unfolded state, the user can fix the clamping mechanism 58 to the rigid support plate 56 of the support frame by bolting, and then connect the vacuum cleaner main body 57 to the clamping mechanism 58, the main body passes through the rigid connecting tube and The ground brush connection is preferably between 60 degrees and 75 degrees. In this case, since the cleaner main body is fixed to the rigid support plate by the clamping mechanism, the ground brush does not slide away from the first frame, and the bottom of the first frame may not be provided with the bottom frame. The rigid support plate may be in the shape of a flat plate, and may have a plurality of holes for the user to fix the bolts, or may be in the shape of a central recess, which is consistent with the shape of the vacuum cleaner main body.

As shown in Fig. 6, in the unfolded state, the second frame can be placed against the wall, the first frame is unfolded relative to the second frame and the wall, and the length of the second frame is greater than the length of the second frame, such that the first frame and the horizontal floor The angle between the second frame and the horizontal ground is smaller than when the vacuum cleaner main body 57 is connected between the first frame and the second frame, and the vacuum cleaner main unit 57 is opposite to the vertical direction. The second frame is tilted.

As shown in FIG. 1 and FIG. 7, the first frame includes a left side 23 and a right side 22. The left side 23 is fixedly provided with a left stop 25, and the right side 22 is fixedly provided with a right stop 26, and the left and right stops are opposite to each other. Forming the limit opening 54, the width of the limit opening 54 (that is, the minimum distance between the left and right stops in the horizontal direction) is greater than 35 cm, and is smaller than the left and right width of the vacuum cleaner main unit 57, that is, perpendicular to the rigid connecting tube The width.

As shown in FIG. 7 and FIG. 8, the bottom frame of the bottom of the first frame is provided with a columnar protrusion for fitting with the opening of the bottom of the floor brush to prevent the floor brush from sliding horizontally in the stored state. The horizontally sliding brush is restrained by the protrusion on the bottom frame, and the curtain of the main body of the vacuum cleaner is disposed on the outer surface of the first frame, so that the position of the vacuum cleaner in the storage state can be raised to prevent the vacuum cleaner main unit 57 from being excessively close to the first The two frames have a relatively large gap between the heights of the first frame and the second frame, so as to set the connection mechanism of the first curtain 52 or other materials, so as to ensure that the user can install more vacuum attachments without bending over. It is placed on the first curtain 52 and the suction attachment can be taken from the first curtain 52 without bending over.

As shown in Fig. 1, a reinforcing bar with a curved end can be hingedly disposed on the right side 22 of the first frame and can be rotated 360 degrees around the axis of rotation on the right side 22. When the support frame is in the unfolded state, the curved end of the reinforcing bar can be hooked onto the bump of the right side edge 31 of the second frame to prevent the first frame and the second frame from approaching each other in the unfolded state. After the curved end of the reinforcing bar is released from the right side edge 31 of the second frame, the first frame and the second frame can be fitted to each other, so that the supporting frame enters the stowed state.

The first frame and the second frame can be directly hinged and can be rotated relative to each other, or can be respectively hinged with a cylinder, and can also be respectively hinged with a platform, and can be fixed after being unfolded, and can be placed flat when stored.

The sides of the first frame and the second frame may each be formed as a telescopic mechanism, and the stoppers on the first frame may be coated with a flexible material. The rigid support plate 56 shown in FIG. 6 can also be replaced with a flexible cloth cover covering the front surface of the first frame, that is, away from the outer surface of the second frame. At this time, the vacuum cleaner main body can be leaned without the clamping mechanism, but leans against On the flexible curtain.

The second frame can be simplified as a rigid rod that is hinged directly or indirectly with the frame for receiving the vacuum cleaner, and can also enter the unfolded state and the stowed state, respectively, similar to the function of the second frame described above. After the simplification, on the one hand, the cost can be reduced, and on the other hand, the three-point positioning on the ground is relatively easy to level. The place where the bottom of the hard rod is in contact with the ground can be made into a "⊥" shape. A disadvantage after the simplification is that the area of the connection mechanism for accommodating the attachment becomes small, and the number of attachments that can be accommodated is reduced. The second frame and the rigid rods simplified by the second frame are support mechanisms for supporting the first frame in the unfolded state to prevent the first frame from falling backward.
