Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and particularly discloses a handheld floor cleaning machine.

Background Art

[0002] With the improvement of living standards, people's requirements for the quality of life are also increasing. Many people lay delicate floorboards or tiles on the floors of their houses. The materials of the floorboards are diverse, such as wooden floorboards or stone floorboards. When there is dirt on the floorboards or tiles and cleaning is required, the conventional method is to clean with a broom, a mop, or a trailer platform. This method is time-consuming and laborious, and it cannot enhance people's interest in cleaning work, which is disadvantageous for maintaining the cleanliness of the indoor environment.

[0003] The direction change of current handheld floor cleaning equipment is generally realized by three parts: a handheld operating component, a base component, and an intermediate double vertical hinge connecting component. The double vertical hinge is rotatable around two perpendicular axes, but there is also a virtual axis perpendicular to these two axes at the same time. A rotational torque from the handle is applied to this virtual axis, and the torque is transmitted to the base through the double vertical hinge, causing the base to change direction.

[0004] In the prior art, since the two perpendicular axes of the double vertical hinge need to be separated by a certain distance so as not to interfere with each other, there is a problem that the acting points of the front-back swing and the left-right swing are not the same. As a result, in the transmission of torque, it is necessary to pass through an eccentric point, so there is a problem that the rotation cannot be synchronously flexible when being transmitted. In addition, there are multiple hinges, and intermediate parts are required, so the number of parts increases and the cost becomes high.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The present invention aims to provide a handheld floor cleaning machine that overcomes the disadvantages and shortcomings of the prior art by easily and flexibly controlling the direction change of the floor cleaning machine, thereby improving the user experience of the floor cleaning machine, while simultaneously reducing the number of parts and cost of the floor cleaning machine. [Means for solving the problem]

[0017] To facilitate understanding for those skilled in the art, the present invention will be further described below with reference to examples and drawings, but the contents described in the embodiments are not intended to limit the present invention. Example 1

[0018] Referring to FIGS. 1 and 2, the handheld floor washer of the present invention includes a guide part (1) having a guide portion (106) and a bottom (2) having a connection portion (201). The guide part (1) and the bottom (2) are directly connected via the guide portion (106) and the connection portion (201). The guide part (1) and the bottom (2) cooperate to enable adjustment in the cleaning direction and the direction perpendicular to the cleaning direction. When the guide part and the connection part are directly connected, they will have a hinge axis (G1) in the cleaning direction and a hinge axis (G2) transverse to the cleaning direction.

[0019] The guide part (1) includes a handle (101), a locking device (102), a clean water tank (103), a sewage tank (104), a vacuum motor module (105), and a guide portion (106).

[0020] The bottom (2) includes a connection portion (201), a holder (202), a disk brush (203), a control module (204), a battery (205), and a squeegee (206). The battery (205) and the squeegee (206) are detachably connected to the bottom (2). The battery (205) is provided with a locking device, and the bottom (2) is provided with a receiving groove for mounting the battery. A locking groove for engaging with the locking device is provided in the receiving groove. Since the engagement between the locking device and the engaging groove in the receiving groove is an existing design, it is not shown in the figure.

[0021] When the guide part and the connection part are directly connected, they form two ring-shaped connection structures. The circular ring of the guide part (106) has a central rotation axis G1 when actually in use, and the ring is rotatable around the axis G1. The circular ring of the connection part (201) similarly has a central rotation axis G2, and the ring is rotatable around the axis G2. When the rotation axis of the rotational motion applied by an external force does not coincide with G1 and G2, the side wall of the circular ring of the guide part (106) contacts the side wall of the circular ring of the connection part (201), and two contact points exist simultaneously. Torques corresponding to the directions of G1 and G2 can be applied by the torques applied to these two contact points. These two contact points are force-receiving points for transmitting torque. That is, the rotation of the guide part (106) is transmitted to the connection part (201) to cause synchronous rotation. Embodiment 2

[0022] Referring to FIGS. 1 and 3, the portable floor cleaner of the present invention includes a guide portion (1) having a guide part (106) and a bottom portion (2) having a connection part (201). The guide portion (1) and the bottom portion (2) are directly connected via the guide part (106) and the connection part (201). The guide portion (1) and the bottom portion (2) can cooperate to be adjusted in the cleaning direction and the direction perpendicular to the cleaning direction. When the guide part and the connection part are directly connected, they will have a hinge axis (G1) in the cleaning direction and a hinge axis (G2) crossing the cleaning direction.

[0023] The guide portion (1) includes a handle (101), a locking device (102), a clean water tank (103), a sewage tank (104), a vacuum motor module (105), and a guide part (106).

[0024] The bottom section (2) includes a connecting section (201), a holder (202), a disc brush (203), a control module (204), a battery (205), and a squeegee (206). The battery (205) and the squeegee (206) are detachably connected to the bottom section (2). The battery (205) is provided with a locking device, and the bottom section (2) is provided with a housing groove for mounting the battery. Within the housing groove, there is a locking groove that engages with the locking device. The locking device and the engagement groove within the housing groove are of an existing design and are therefore not shown.

[0025] The guide portion and the connecting portion are directly connected, forming a ball groove type connection structure. The ball wall of the guide portion (106) has a central rotation axis G1 when actually used, and the ring is capable of rotational movement around axis G1. Similarly, the ball wall of the connecting portion (201) has a central rotation axis G2, and the ring is capable of rotational movement around axis G2. If the rotation axis of the rotational motion applied by an external force does not coincide with G1 and G2, the ball wall sidewall of the guide portion (106) and the ball wall sidewall of the connecting portion (201) come into contact, and two contact points exist simultaneously. Torque applied to these two contact points can apply torque corresponding to the G1 and G2 directions, respectively. These two contact points are force-receiving points that transmit torque. In other words, the rotation of the guide portion (106) is transmitted to the connecting portion (201), causing it to rotate synchronously.

[0026] Naturally, those skilled in the art can, depending on their specific needs, configure the two ring-shaped connecting structures as incomplete rings, or so that the two rings are of different sizes or diameters. Furthermore, those skilled in the art may extend the ball-groove connecting structure to a universal joint structure, all of which can satisfy the torque transmission function.

[0027] In the connection configuration of the present invention, since there are only two parts, component costs can be reduced and maintainability can be improved. Also, because there are only two static parts, the component strength can be increased within the same spatial range, thereby increasing the load capacity. Furthermore, in this configuration, the distance between the two axes is very small, and the resulting eccentric displacement is very small, which is equivalent to concentric transmission of torque, resulting in no wobble and flexible rotation.

[0028] From the above, it can be seen that the present invention, by possessing the above-mentioned excellent properties, enhances the practicality of its use by providing effects not found in the prior art, and thus becomes an extremely practical product.

[0029] The above describes only preferred embodiments of the present invention, and those skilled in the art can modify the specific embodiments and scope of application in accordance with the spirit of the present invention. The contents of this specification should not be construed as limiting the present invention.
