Description

FIELD OF THE DISCLOSURE

The present disclosure relates to the technical field of cleaning equipment and in particular to a cleaning device.

BACKGROUND OF THE DISCLOSURE

Environmental health is an important factor affecting the quality of life. Therefore, as people's requirements for quality of life continue to increase, the requirements for environmental hygiene are correspondingly higher and higher. However, the work pressure of modern people is increasing day by day. There is an urgent need to reduce the heavy workload associated with cleaning, so there is a lot of equipment for cleaning the ground to improve environmental sanitation. Some cleaning devices use a combination of a cleaning head and a body, such as an upright vacuum cleaner. The body is pivotally attached to the cleaning head. The cleaning head is used to clean the floor. The body is used to push the cleaning head. When the cleaning device is not being used, the body is positioned to be erect with respect to the cleaning head and then locked to the cleaning head by a locking mechanism. When the cleaning device is to be used, the cleaning head is unlocked from the body so that the body can be tilted with respect to the cleaning head. The locking mechanism currently used for this type of cleaning device locks the upright body to the cleaning head using elastic force, and the durability of the locking mechanism is low. After locking the body several times, the locking mechanism will appear loose or fail, and the related components crack so that the upright body can no longer lock onto the cleaning head.

In order to facilitate an understanding of the present disclosure, the present disclosure will be more fully described below. However, the present disclosure may be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used in the description of the present disclosure herein is for the purpose of describing particular embodiments only and is not intended to limit the present disclosure.

Embodiment 1

Referring to FIGS. 1 and 2, the cleaning device of an embodiment includes a cleaning head 10, a body 20, and a locking mechanism 30. The body 20 is hinged to the cleaning head 10. The locking mechanism 30 includes a first magnetic member 31 disposed on the cleaning head 10 and a second magnetic member 32 disposed on the body 20. As shown in FIG. 1, when the body 20 is upright, the first magnetic member 31 couples to the second magnetic member 32, and the body 20 is locked to the cleaning head by the magnetic attraction between the first magnetic member 31 and the second magnetic member 32. As shown in FIG. 2, when a cleaning operation is required, the user pulls the body 20 backward to overcome the magnetic attraction force between the first magnetic member 31 and the second magnetic member 32, so that the second magnetic member 32 is moved away from the first magnetic member 31 is. At this time, the body 20 can be tilted freely, and the cleaning device performs the cleaning work.

A handle 21 is provided at one end of the body 20 remote from the cleaning head 10. An outer surface of the handle 21 is provided with an elastic layer so that the person feels comfortable when holding the handle 21. The first magnetic member 31 and the second magnetic member 32 are equal in number and are arranged in a one-to-one correspondence. The number of first magnetic members 31 and the number of second magnetic members 32 is one or two. When the cleaning device includes one first magnetic member 31 and one second magnetic member 32, the first magnetic member 31 and the second magnetic member 32 are located on one side of the cleaning head 10. When the cleaning device includes two first magnetic members 31 and two second magnetic members 32, one of the first magnetic members 31 and one of the second magnetic member 32 are located on each lateral side of the cleaning head 10, which can enable the body 20 to be biased laterally when it is locked upright on the cleaning head 10. In turn, the body 20 can be better locked on the cleaning head 10. In the present embodiment, the number of first magnetic members 31 and the number of second magnetic members 32 is two, and one of each of the first magnetic members 31 and the second magnetic members 32 are located on each side of the cleaning head 10. In this embodiment, when the second magnetic member 32 is attracted to the first magnetic member 31, a spaced is defined between the first magnetic member 31 and the second magnetic member 32. The arrangement is such that collision damage between the first magnetic member 31 and the second magnetic member 32 does not occur.

The first magnetic member 31 and the second magnetic member 32 are magnets. When the body 20 stands upright, the second magnetic member 32 is driven by the body 20 near the first magnetic member 31, and the second magnetic member 32 cuts into the magnetic field of the first magnetic member 31 from a lateral side of the first magnetic member 31. The first magnetic member 31 also cuts into the magnetic field of the second magnetic member 32 from one side of the second magnetic member 32. The magnetic flux of the first magnetic member 31 and the second magnetic member 32 gradually increase under the influence of the magnetic fields of each other. When the second magnetic member 32 is facing the first magnetic member 31, the second magnetic member 32 stops moving. At this time, the body 20 stands upright. The magnetic fluxes of the first magnetic member 31 and the second magnetic member 32 both reach the maximum, and the magnetic attraction forces of the first magnetic member 31 and the second magnetic member 32 also reach the maximum, so that the body 20 can be securely locked on the cleaning head 10. The attraction of the first magnetic member 31 and the second magnetic member 32 is achieved through this movement. When the first magnetic member 31 and the second magnetic member 32 are separated, the first magnetic member 31 can be driven by the body 20 to cut the magnetic field line laterally separated from the second magnetic member 32 until it moves to the side of the second magnetic member 32, so that it eliminates the need to overcome the excessive magnetic attraction of the magnetic pole of the first magnetic member 31 and the magnetic pole of the second magnetic member 32. The first magnetic member 31 is made easier to separate from the second magnetic member 32 for the purpose of easily tilting the body 20.

Each of the first magnetic member 31 and the second magnetic member 32 has a rectangular parallelepiped shape or a cylindrical shape. If the first magnetic member 31 and the second magnetic member 32 each have a rectangular parallelepiped shape, the first magnetic member 31 and the second magnetic member 32 each include two square end faces four square sides located between the square end faces. When the second magnetic member 32 is attracted to the first magnetic member 31, a square end face of the second magnetic member 32 is facing a square end face of the first magnetic member 31 or a square side of the second magnetic member 32 faces a square side of the first magnetic member 31. If the first magnetic member 31 and the second magnetic member 32 each have a cylindrical shape, the first magnetic member 31 and the second magnetic member 32 each include a curved side surface and two circular flat end faces. When the second magnetic member 32 is attracted to the first magnetic member 31, a circular flat end face of the second magnetic member 32 is facing a circular flat end face of the first magnetic member 31 or a curved side surface of the second magnetic member 32 is facing a curved side surface of the first magnetic member 31.

In this embodiment, the first magnetic member 31 and the second magnetic member 32 each have a rectangular parallelepiped shape. When the second magnetic member 32 is attracted to the first magnetic member 31, the curved side surface of the second magnetic member 32 faces the curved side surface of the first magnetic member 31. The first magnetic member 31 is detachably mounted on the cleaning head 10, and the second magnetic member 32 is detachably mounted on the body 20. For example, the first magnetic member 31 is connected to the cleaning head 10 by screws, and the second magnetic member 32 is connected to the body 20 by screws.

Compared with the conventional locking mechanism for locking the body 20 and the cleaning head 10, the locking mechanism 30 of the cleaning device of the present invention is accomplished by the magnetic attraction force of the first magnetic member 31 and the second magnetic member 32. Thus, it does not easily fail and the life of the locking mechanism is improved.
