Description

Technical Field

[0001] This utility model belongs to the field of vacuum cleaners, specifically a vacuum cleaner that can be placed upright. Background Technology

[0002] Vacuum cleaners are common cleaning appliances in homes and offices. However, when vacuum cleaners are not in use or are not in use, the main unit is difficult to keep upright and is prone to tipping over. Therefore, they need to be placed against a wall to prevent tipping over, which is inconvenient to use. Moreover, even when placed against a wall, there is still a risk that the vacuum cleaner will tip over, which may cause obstruction or even collision and damage to the vacuum cleaner parts. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a vacuum cleaner that can be placed upright.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A vertically placed vacuum cleaner includes a vacuum cleaner main unit and a floor brush located at the bottom of the main unit. The floor brush is provided with a connecting pipe, which has a hinge shaft to be hinged to the floor brush. A suction pipe is inserted into the upper part of the connecting pipe, which connects to the vacuum cleaner main unit and enables rotational connection between the floor brush and the vacuum cleaner main unit. The floor brush includes a front roller brush and a rear roller. The connecting pipe is provided with a support plate that rotates with it. A support platform is provided on the floor brush corresponding to the position of the support plate. The bottom end face of the support plate abuts against the support platform, so that the connecting pipe is supported and kept in a vertical state.

[0006] The hinge shaft has a radially protruding locking post, and a locking device is arranged around the hinge shaft; the locking device includes a locking platform, and when the locking post is engaged with the locking platform, the rotation of the connecting pipe is limited; when the locking post is disengaged from the locking platform, the connecting pipe can rotate freely around the hinge shaft.

[0007] The locking device is located on the side of the hinge shaft and includes a spring and a flip arm. The bottom end of the flip arm is hinged to the bottom of the floor brush housing and can swing in the direction of the hinge shaft. The locking platform is arranged on the upper back side of the flip arm. The spring acts between the front side of the flip arm and the floor brush housing. Under the push of the spring, the flip arm tilts in the direction of the hinge shaft so that the locking platform engages with the locking post of the hinge shaft.

[0008] The card plate has a slot for the card post to be inserted.

[0009] The lower part of the back side of the flipping arm is provided with a boss, and the outer peripheral contour of the hinge shaft forms a cam structure eccentrically. When the connecting pipe rotates backward, the outer peripheral contour surface of the hinge shaft pushes the boss, causing the flipping arm to swing away from the hinge shaft, so that the locking platform and the locking post are disengaged.

[0010] The support plate is symmetrically provided with horizontally extending support columns on both sides. The support plate abuts against the support platform while the support columns abut against the top surface of the floor brush.

[0011] The surface of the support platform is lower than the top surface of the floor brush. Two grooves are symmetrically formed on the support platform, and two corresponding insertion posts are formed at the bottom of the support plate to fit into the grooves.

[0012] The portion between the two grooves is a trapezoidal platform, and a trapezoidal groove is formed between the two inserts for the trapezoidal platform to be inserted.

[0013] The beneficial effects of this utility model are as follows: The floor brush of this utility model has a front roller brush and a rear roller. The support of the roller brush and the roller can make the floor brush have good stability on the ground. When the connecting pipe abuts against the support platform through the support plate, on the one hand, the support platform supports the connecting pipe and the vacuum cleaner host to maintain the vertical state by cooperating with the support plate. On the other hand, the floor brush provides a stable base so that the vacuum cleaner can be placed on the ground in an upright state, thereby achieving the purpose of users placing it at will when pausing or stopping work.

[0021] Reference Figures 1 to 6 A vacuum cleaner includes a vacuum cleaner main unit 1 and a floor brush 2 located at the bottom of the main unit. The floor brush 2 is provided with a connecting pipe 21. The connecting pipe 21 is provided with a hinge shaft 211 to achieve hinge connection with the floor brush 2. A vacuuming pipe 11 is inserted into the upper part of the connecting pipe 21 to connect the vacuum cleaner main unit 1 and realize the rotatable connection between the floor brush 2 and the vacuum cleaner main unit 1.

[0022] The floor brush 2 includes a front roller brush and a rear roller. The connecting pipe 21 is provided with a support plate 212 that rotates with it. The floor brush 2 is provided with a support platform 22 corresponding to the position of the support plate 212. When the vacuum cleaner is not in use, the main unit is raised and the bottom end face of the support plate 212 abuts against the support platform 22, so that the connecting pipe 21 is supported and kept in a vertical state. The floor brush has good stability on the ground under the support of the roller brush and the roller, providing a stable base so that the vacuum cleaner can be placed on the ground in an upright state, thereby achieving the purpose of users placing it at will when pausing or stopping work.

[0023] like Figure 5 , Figure 6 As shown, the hinge shaft 211 has a radial protrusion forming a locking post 213, and the hinge shaft 211 is provided with a peripheral locking device 23; the locking device 23 includes a locking platform 231, and when the locking post 213 is locked into the locking platform 231, the rotation of the connecting pipe 21 is limited; when the locking post 213 is disengaged from the locking platform 231, the connecting pipe 21 can rotate freely around the hinge shaft 211. Preferably, the locking device 23 is located on the side of the hinge shaft 211 and includes a spring 233 and a flip arm 232. The bottom end of the flip arm 232 is hinged to the bottom of the housing of the floor brush 2 and can swing towards the hinge shaft 211. The locking platform 231 is arranged on the upper back side of the flip arm 232 and a locking groove 234 is formed on the locking platform 231 for the locking post 213 to be inserted. The spring 233 acts between the front side of the flip arm 232 and the housing of the floor brush 2. Under the push of the spring 233, the flip arm 232 tilts towards the hinge shaft 211 so that the locking platform 231 and the locking post 213 of the hinge shaft 211 cooperate to maintain a locked state. To achieve unlocking, a boss 235 is provided on the lower back side of the flip arm 232. The outer peripheral contour of the hinge shaft 211 is eccentrically formed into a cam structure. When the connecting pipe 21 rotates backward, the outer peripheral contour surface of the hinge shaft 211 pushes the boss 235, causing the flip arm 232 to swing away from the hinge shaft 211, so that the locking platform 231 disengages from the locking post 213.

[0024] like Figure 3 , Figure 4As shown, preferably, the support plate 212 has symmetrically arranged laterally extending support columns 214 on both sides. While the support plate 212 abuts against the support platform 22, the support columns 214 abut against the top surface of the floor brush 2. The multi-point support makes the vacuum cleaner more stable when it is in an upright position. In order to make the vacuum cleaner stand more stably, the surface of the support platform 22 is lower than the top surface of the floor brush 2. That is, the support platform 22 is a sunken platform, so that the support plate 212 can be supported on the support platform 22 in the form of being inserted into the top of the floor brush 2. After sunken, the side walls around the support platform 22 will also provide a certain support for the support plate 212. Furthermore, two grooves 221 are symmetrically formed on the support platform 22, and two insertion posts 215 are correspondingly formed at the bottom of the support plate 212 to fit into the grooves 221. The mutual cooperation between the insertion posts 215 and the grooves 221 strengthens the connection stability between the support plate 212 and the support platform 22. Furthermore, since the connecting pipe 21 and the floor brush 2 are rotating, in order to avoid the cooperation between the groove 221 and the post 215 affecting the rotating movement of the connecting pipe 21, the part between the groove 221 is a trapezoidal platform 222, and a trapezoidal groove 216 is formed between the two posts 215 for the trapezoidal platform 222 to be inserted. The structure of the trapezoidal platform 222 and the trapezoidal groove 216 can form a guiding slope so that when the connecting pipe 21 is rotated to the upright state, the post 215 on the support plate 212 can be easily inserted into the groove 221 of the support platform 22 so that the support plate 212 is stably supported on the support platform 22.
