Description

Cleaning apparatus

Technical Field

The embodiment of the utility model relates to the field of household appliances, in particular to cleaning equipment.

Background

With the increasing level of living, cleaning equipment, such as cleaners, has been moved into thousands of households.

A suction opening is usually formed in the bottom of the cleaner for sucking dirt, for example, on the floor surface. The bottom of the dust collector is at a certain distance from the ground, so that dirt in the front and back of the dust collector can be sucked when the dust collector moves forwards and backwards. However, during suction, an open suction area is formed at the suction opening, which results in a suction force that is insufficient to remove dirt, in particular large or heavy particles, from the floor surface in a particularly effective manner.

In the prior art, a stop strip is arranged on the rear side of the suction inlet, which is usually fixedly arranged and remains in contact with the floor surface at all times when the cleaner is moved back and forth for suction. However, this configuration causes dirt behind the cleaner to be blocked by the stopper bar and not sucked when the cleaner moves backward to suck dust.

Furthermore, since the stopper bar is always in contact with the floor, the stopper bar is worn out and eventually damaged when the cleaner is frequently moved back and forth (back and forth), which also increases the cost of replacement of the stopper bar (accessory).

Accordingly, there remains a continuing need for improvements to at least some of the problems described above.

Disclosure of Invention

It is an object of an embodiment of the utility model to provide a cleaning device. Not only the disadvantages of the cleaning devices of the prior art can be overcome by means of at least one embodiment of the utility model, but also a reliable function can be realized particularly simply without changing the structure of the existing components and at a cost advantage.

According to a first aspect of the present utility model, there is provided a cleaning apparatus movable in a first direction and a second direction opposite to the first direction for cleaning, the cleaning apparatus comprising:

a main body portion; and

a cleaning portion connected to the main body portion, the cleaning portion being configured to be adapted to generate a negative pressure and to clean dirt on a surface to be cleaned,

a suction opening for sucking dirt into the cleaning part is formed in the bottom of the cleaning part,

a stop assembly is arranged at the suction opening in the first direction, the stop assembly comprising a rotationally movable stop having a closed position and an open position, the stop assembly rotating the stop between the closed position and the open position with movement of the cleaning device between the first direction and the second direction.

This embodiment of the utility model enables the stopper to rotate between the closed position and the open position with different directions of movement of the cleaning device, thus achieving an enhanced cleaning effect of the cleaning device and reducing wear of the stopper, thus increasing the service life.

In order to make the technical problems, technical solutions and advantageous technical effects to be solved by the present utility model more apparent, the present utility model will be further described in detail with reference to the accompanying drawings and a plurality of exemplary embodiments. It should be understood that the detailed description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the utility model. It is noted that directional terms used in the description refer to the normal use state of the cleaning device for convenience of description and are not to be construed as absolute limitations of the corresponding features.

Next, the cleaning device 1 of the present utility model is described with reference to fig. 1 and 2.

Fig. 1 shows a schematic view of a cleaning device 1 according to an embodiment. The cleaning apparatus 1 includes a main body portion 10 and a cleaning portion 20 connected to the main body portion 10. As shown in fig. 1, the main body portion 10 is constructed in an elongated shape and is constructed at one end thereof with a grip portion 101, and a user can grasp the grip portion 101 to operate the cleaning apparatus 1. The cleaning portion 20 is configured to be adapted to generate negative pressure and clean a surface 40 to be cleaned (see also fig. 3 to 6). In this embodiment, the cleaning device 1 is configured as a vacuum cleaner, in particular a vacuum cleaner which can be operated without a power cord. Also shown in fig. 1 is an XYZ coordinate system, wherein X represents the direction of movement of the cleaning device 1, Y represents a direction transverse to this direction of movement, and Z represents a vertical direction.

Fig. 2 shows a top view of the cleaning section 20 of the cleaning device 1 in fig. 1. In connection with fig. 1, a battery (not shown) is arranged in the main body part 10, and a motor, a blower (not shown) and a roller brush 204 are arranged in the housing of the cleaning part 20, the battery being electrically connected to and supplying energy to the motor.

According to one embodiment, the housing of the cleaning section 20 is made up of an upper cover 205 and a bottom cover 206, which are assembled together to house the motor, fan and roller brush 204.

A suction opening 201 for sucking dirt into the cleaning part 20 is provided at the bottom or bottom cover 206 of the cleaning part 20. The motor drives the roller brush 204 to rotate to collect dirt on the surface 40 to be cleaned in the direction of the suction opening 201 and drives the blower to generate negative pressure to suck the dirt from the suction opening 201 into the cleaning part 20.

As shown in fig. 2, a front wheel 207 and a rear wheel 208 are provided on the bottom of the cleaning portion 20. In this embodiment, the positions of the front wheels 207 and the rear wheels 208 are relative to the X direction in fig. 1. When the cleaning device 1 is in operation, i.e. when the user holds the grip 101 to move the cleaning device 1 back and forth in the X-direction (left and right in the drawing), the front wheel 207 and the rear wheel 208 respectively rotate in the same direction and roll on the surface 40 to be cleaned.

At the suction opening 201 a stop assembly 30 is arranged. According to one embodiment, the stop assembly 30 includes a rotationally movable stop 302, which stop 302 is configured as an elastic stop. In one embodiment, the stop 302 is a rubber or plastic strip.

According to one embodiment, the stop assembly 30 comprises a rotation shaft 301 extending along the suction opening 201, the stop 302 being fixed to the rotation shaft 301 and rotating with the rotation shaft 301. It is also conceivable to integrally form the stopper 302 with the rotation shaft 301 as a single member.

As shown in fig. 2, the rotation shaft 301 may be mounted on the bottom of the cleaning portion 20 by means of a flap 305 and rotatably supported.

According to one embodiment, a stop 304 is configured on the rotation shaft 301, which is adapted to limit the rotational movement of the stop 302 to a predetermined position. The stopper 304 may be integrally formed with the rotation shaft 301. Thus simplifying manufacturing and assembly costs and improving structural strength. The rotation shaft 301 and the stopper 304 are made of plastic, thereby reducing the mass while securing the function of the stopper assembly 30.

In this embodiment, the stopper 304 is configured as a bump.

In addition, the stopper assembly 30 includes a roller 303, and the roller 303 is fixedly connected to the rotation shaft 301 and is in frictional contact with the surface 40 to be cleaned. In this embodiment, the roller 303 is non-rotatable with respect to the rotation shaft 301, that is, the roller 303 rotates in synchronization with the rotation of the rotation shaft 301. The rollers 303 may be mounted on both ends of the rotation shaft 301 in an interference fit manner. Of course, the rollers 303 may be integrally formed at both ends of the rotation shaft 301.

The technical solution of the present utility model is further described below with reference to fig. 1 and 2 and with reference to fig. 3 to 6.

Fig. 3 shows a side view of the cleaning part 20 in fig. 2. Fig. 4 shows a partial enlarged view of fig. 3, wherein the stop 302 is in the closed position P1. Fig. 5 shows a side view of the cleaning part 20 in fig. 2. Fig. 6 shows a partial enlarged view of fig. 5, in which the stop 302 is in the open position P2.

In connection with fig. 1, in fig. 3 and 4, in order to clean dirt on the surface 40 to be cleaned, the cleaning device 1 is currently moved in a first direction a, i.e. in the same direction X. The roller 303 of the stopper assembly 30 located behind the suction opening 201 in the first direction a (to the right of the suction opening 201 in fig. 3) contacts the surface 40 to be cleaned and rolls (rotates) synchronously in the first rotation direction R1 (counterclockwise direction) as the front wheel 207 and the rear wheel 208 roll on the surface 40 to be cleaned. The roller 303 rotates the rotation shaft 301, so that the stopper 302 fixed to the rotation shaft 301 also rotates toward the surface 40 to be cleaned in the first rotation direction R1.

According to one embodiment, a first limit fitting portion 202 is configured on the bottom cover 206, and the first limit fitting portion 202 is integrally formed on the bottom cover 206 and is capable of being fitted with a limit portion 304 on the rotation shaft 301 to limit the rotation angle of the rotation shaft 301 to a predetermined angle.

As shown in fig. 4, as the cleaning device 1 moves in the first direction a and when the stopper 304 comes into contact with the first stopper fitting portion 202, the stopper 304 is rotationally stopped by the first stopper fitting portion 202, and thus the stopper 302 is no longer able to continue to rotate toward the surface 40 to be cleaned and is in the closed position P1, thereby forming a relatively sealed space behind the suction opening 201 in the first direction a. Dirt located in front of the suction opening 201 in the first direction a can be efficiently sucked into the suction opening 201, whereby the power from the motor can be efficiently utilized or the cleaning (dust suction) effect of the cleaning portion 20 can be improved.

According to one embodiment, when the stopper 302 is in the closed position P1, the stopper 302 is in abutment with the surface 40 to be cleaned. That is, when the stopper 304 is stopped on the first stopper fitting portion 202 in the first rotation direction R1, the stopper 302 just contacts the surface 40 to be cleaned and the contact portion of the stopper 302 and the surface 40 to be cleaned may be slightly elastically deformed due to the material thereof.

If the cleaning apparatus 1 continues to move in the first direction a, the roller 303 cannot continue to rotate in the first rotation direction R1 due to the stopper action of the stopper 304, and thus the roller 303 is changed from rolling against the surface to be cleaned 40 to sliding on the surface to be cleaned 40.

In connection with fig. 1, in fig. 5 and 6, the cleaning device 1 is moved in a second direction B (opposite to the X-direction) opposite to the first direction a. The roller 303 of the stopper assembly 30 contacts the surface to be cleaned 40 and rolls (rotates) synchronously in the second rotational direction R2 (clockwise) as the front wheel 207 and the rear wheel 208 roll on the surface to be cleaned 40. The roller 303 rotates the rotation shaft 301, so that the stopper 302 fixed to the rotation shaft 301 also rotates in the second rotation direction R2 in a direction away from the surface 40 to be cleaned.

According to one embodiment, a second limit engaging portion 203 is configured on the bottom cover 206, and the second limit engaging portion 203 is integrally formed on the bottom cover 206 and can engage with a limit portion 304 on the rotation shaft 301 to limit the rotation angle of the rotation shaft 301 to another predetermined angle.

As shown in fig. 6, as the cleaning device 1 moves in the second direction B and when the stopper 304 comes into contact with the second stopper fitting portion 203, the stopper 304 is rotationally stopped by the second stopper fitting portion 203, and thus the stopper 302 can no longer continue to rotate away from the surface 40 to be cleaned and is in the open position P2. Here, the stopper 302 has a distance H from the surface 40 to be cleaned. Thus, dirt in front of the stop assembly 30 in the second direction B (to the right of the stop assembly 30 in the drawing) can pass this distance H and come to the suction opening 201 due to the movement of the cleaning device 1 in the second direction B. Thus, the stopper 302 does not obstruct dirt, e.g. large particle objects, from passing the bottom of the cleaning section 20 when the cleaning device 1 is moved in the second direction B.

According to one embodiment, the distance H is between 2.5mm and 6.3 mm.

If the cleaning apparatus 1 continues to move in the second direction B, the roller 303 cannot continue to rotate in the second rotational direction R2 due to the stopper action of the stopper 304, and thus the roller 303 is changed from rolling against the surface to be cleaned 40 to sliding on the surface to be cleaned 40.

In the present utility model, by the rotation of the stopper 302 in different directions with different directions of movement of the cleaning device 1, a flexible and efficient cleaning manner can be achieved and wear of the stopper 302, e.g. an elastic rubber strip, can be reduced.

Although specific embodiments have been described above, these embodiments are not intended to limit the scope of the disclosure, even where only a single embodiment is described with respect to a particular feature. The characteristic examples provided in the present disclosure are intended to be illustrative, not limiting, unless stated differently. In a specific implementation, the features may be combined with one another where technically feasible according to the actual requirements. Various substitutions, alterations, and modifications can be made without departing from the spirit and scope of the utility model.
