The present invention relates to a vacuum cleaner, especially a vacuum cleaner capable of returning to standing.

An existing upright vacuum cleaner includes a vacuum cleaner body and a handle connected to the vacuum cleaner body. A user can perform vacuuming operations on the ground by using the vacuum cleaner body by holding the handle.

However, when the upright vacuum cleaner is not in use, after swinging the handle to an upright angle, the vacuum cleaner body can stand on the ground with a corresponding surface, which can reduce the occupied space.

However, if the swing angle of the handle is not precisely directed upwards, the vacuum cleaner body will not be able to stand up due to the inclination, thereby causing the entire upright vacuum cleaner to tip over, and the user must turn the upright vacuum cleaner repeatedly, which is quite inconvenient.

Therefore, the purpose of the present invention is to provide a vacuum cleaner that overcomes the disadvantages of the prior art.

Therefore, the new vacuum cleaner includes a housing, a fan unit, a filter unit, and an electric control unit.

The housing includes a bottom wall, a working curved wall that curves arc-shaped backwards and upwards from the bottom wall, and a peripheral wall extending upward from the outer edges of the bottom wall and the working curved wall, the working curved wall has A dust suction port, the peripheral wall has an air vent, the housing surrounds a first accommodating space defined upwardly and sequentially spaced from the bottom wall, a second accommodating space communicating with the air vent, and a second accommodating space A third accommodating space of the accommodating space, and a dust suction channel connecting the dust suction port and the third accommodating space and passing through the rear of the first accommodating space and the rear of the second accommodating space, the fan unit includes A fan disposed in the second accommodating space, the filter unit includes a filter screen detachably disposed in the housing to separate the second accommodating space and the third accommodating space, and the electric control unit It includes a motor module for interlocking the fan, the motor module has a motor body disposed in the first accommodating space adjacent to the bottom wall, and a motor body rotatably disposed on the motor body The motor body interlocks and penetrates into the second accommodating space to connect with the fan and its own axis passes through the motor rotating shaft of the bottom wall.

The effect of the present invention is that the vacuum cleaner can automatically recover by the arrangement of the bottom wall and the working curved wall, and the arrangement of the motor body and its own axis center adjacent to the bottom wall through the motor rotating shaft of the bottom wall Standing and not easy to fall.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same number.

Referring to FIGS. 1, 2, and 3, a first embodiment of the new vacuum cleaner includes a housing 2, a fan unit 3, a filter unit 4, and an electric control unit 5.

The housing 2 includes a bottom wall 21, a working curved wall 22 curved arcuately from the bottom wall 21 rearward and upward, and a peripheral wall extending upward from outer peripheral edges of the bottom wall 21 and the working curved wall 22 twenty three.

The working curved wall 22 has a dust suction port 221, and the peripheral wall 23 has four exhaust ports 231. In this embodiment, the number of the air vents 231 is four, but it is not limited to this, and one or other number can be set as required.

The housing 2 surrounds a first accommodating space 24 spaced upwardly and sequentially defined from the bottom wall 21, a second accommodating space 25 communicating with the exhaust ports 231, and a second accommodating space 25 The third accommodating space 26, the housing 2 further defines a space connecting the dust suction port 221 and the third accommodating space 26 through the rear of the first accommodating space 24 and the rear of the second accommodating space 25 Vacuum channel 27.

The fan unit 3 includes a fan 31 disposed in the second accommodating space 25.

The filter unit 4 includes a filter 41 detachably disposed in the housing 2 to separate the second accommodating space 25 and the third accommodating space 26. It should be noted that filter paper can also be provided on the filter 41 to facilitate replacement.

The electric control unit 5 includes a motor module 51 for interlocking the fan 31, a control module 52 electrically connected to the motor module 51, and an electric connection to the control module 52 to sense the tilt of the housing 2 The status of the tilt sensor 53. In this embodiment, the tilt sensor 53 uses mercury as a basis for measuring tilt due to the tilted flow position, but it is not limited to this.

The motor module 51 has a motor body 511 disposed in the first accommodating space 24 adjacent to the bottom wall 21, and a motor body 511 rotatably disposed on the motor body 511 and can be linked and penetrated by the motor body 511 The second accommodating space 25 is connected to the fan 31 and its axis passes through the motor shaft 512 of the bottom wall 21.

In use, after a user drives the motor body 511 to run, the motor shaft 512 will drive the fan 31 to rotate, so that the airflow is sucked in from the dust suction port 221, and sequentially passes through the dust suction channel 27 and the third accommodation After the space 26, it is filtered through the filter 41, passes through the fan 31 in the second accommodating space 25, and is finally discharged through the exhaust ports 231, so as to achieve the effect of vacuuming through the vacuum port 221.

The vacuum cleaner can be switched to a tilt sensing mode. In this tilt sensing mode, when the user holds the vacuum cleaner, the working curved wall 22 is close to the floor and the vacuum opening 221 is facing the floor. At this time, the housing 2 is inclined In this state, when the tilt sensor 53 senses that the housing 2 is tilted, the control module 52 controls the motor module 51 to operate and uses the vacuum port 221 for vacuuming. When the housing 2 stands with the bottom wall 21 attached to the ground, and the tilt sensor 53 senses that the housing 2 is not tilted, the control module 52 controls the motor module 51 to stop operating without Vacuum again.

When the user finishes vacuuming, as long as the vacuum cleaner is pushed in the direction that makes the bottom wall 21 close to the ground, the motor body 511 is adjacent to the bottom wall 21 and the axis of the motor shaft 512 passes through the bottom wall 21. Therefore, the center of gravity of the heavier motor module 51 will pass through the bottom wall 21, so the vacuum cleaner will stand with the bottom wall 21 attached to the ground, guided by the curved surface of the working curved wall 22, Even if the user does not place the vacuum cleaner until it is completely upright, the vacuum cleaner will automatically return to standing due to the influence of the center of gravity, thus making the vacuum cleaner difficult to tip over.

Referring to FIGS. 4, 5, and 6, a second embodiment of the present invention is similar to the first embodiment, and the difference is that:

The vacuum cleaner further includes a first accessory unit 6, the first accessory unit 6 includes a suction head seat 61 detachably disposed at the bottom of the housing 2, and a handle 62 detachably disposed at the top of the housing 2 .

Referring to FIGS. 3, 6, and 7, the tip holder 61 has a front bottom 611 for carrying the bottom wall 21, and an arc curved backward and upward from the front bottom 611 to carry the working curved wall 22 of the rear bottom curved portion 612, a part is connected to the outer portion of the front bottom 611 and the rear bottom curved portion 612 to limit the surrounding portion 613 of the housing 2, and a portion extending from the rear bottom curved portion 612 upward and used The dust suction port 221 is penetrated to communicate with the dust suction channel 27 and the mounting tube 614 under the rear bottom curved portion 612.

5, 8 and 9, the handle 62 has a sleeve 621 connected to the top of the peripheral wall 23 of the housing 2, a grip 622 connected to the sleeve 621 on the opposite side of the housing 2, and a The brush 623 is movably disposed in the sleeve 621.

3, 5, and 7, when in use, through the extension of the tip holder 61 and the handle 62, the user can easily stand and hold the handle 62 to use the vacuum cleaner, when the motor module 51 is operating, The airflow will be sucked into the dust suction channel 27 through the bottom of the installation tube 614, and finally discharged through the exhaust ports 231.

When the user finishes vacuuming, as long as the handle 62 is pushed toward the front bottom 611 close to the ground, guided by the curved surface of the rear bottom curved portion 612, the vacuum cleaner will stick the front bottom 611 to the ground While standing, even if the user does not place the vacuum cleaner completely upright, the vacuum cleaner will automatically return to standing, thus also making the vacuum cleaner difficult to tip over.

5, 8 and 9, in addition, when the handle 62 is separated from the housing 2, after moving the brush 623 out of the sleeve 621 (see FIG. 9 ), it can also be used as a broom, and After vacuuming, the brush 623 is retracted into the sleeve 621 (see FIG. 8), and then the casing 2 can be sleeved back to continue use.

In this way, the second embodiment can also achieve the same purposes and effects as the first embodiment described above.

Referring to FIGS. 10, 11, and 12, a third embodiment of the present invention is similar to the first embodiment, and the difference is that:

The vacuum cleaner further includes a second accessory unit 7 for the housing 2 to be tilted backwards. The second accessory unit 7 includes a base 71, and a base is disposed at the bottom of the base 71 and can be controlled to drive the The seat group 71 moves the wheel group 72.
