Description

Technical Field

[0001] This utility model belongs to the field of rotary mops, specifically an automatic mop disc lifting device. Background Technology

[0002] Spin mops, as an efficient and convenient cleaning tool, have been widely used in various scenarios such as homes and offices. Their core function is to fill the mop head with water and spin it dry by cooperating with the water supply device and the rotating shaft of the water supply device inside the mop head.

[0003] The principle is as follows: when the mop head rotates rapidly around the shaft, the counterweight inside it opens and moves to both sides under the action of centrifugal force, thereby driving the entire mop head to rise upward along the shaft, so that the mop head is separated from the water supply component in the mop bucket, realizing the function of wringing out the mop. When the speed of the mop head decreases or the centrifugal force is small, the counterweight returns to its original position, and the mop head falls back to its initial position. At this time, the water supply device inside the mop head waters the mop to meet the needs of continuous cleaning.

[0004] However, existing mop disc lifting devices have significant drawbacks: to achieve stable movement of the counterweight and precise lifting of the mop disc, complex linkage mechanisms, guide structures, and reset components are typically required, resulting in a large number of components and cumbersome assembly processes. This not only increases manufacturing costs but also reduces the reliability of the device. Furthermore, since the movement trajectory of the counterweight relies on the constraints of complex guide mechanisms, long-term use can lead to wear and jamming of components, resulting in uneven lifting or inaccurate reset of the mop disc. This directly affects the stability of the water filling and wringing functions, thereby reducing the user experience and lifespan of the rotary mop. Utility Model Content

[0005] In view of the shortcomings of existing rotary mops, the technical problem to be solved by this utility model is to simplify the structure of the rotary mop disc lifting device, improve its working stability, and at the same time improve the smoothness of the mop disc rotation.

[0006] To achieve the above objectives, according to one aspect of the present invention, the present invention is implemented through the following technical measures: an automatic mop tray lifting device, comprising: The support base has a central hole for the rotating shaft inside the mop bucket to pass through, so that the rotating shaft can be engaged with the mop disc. The lifting seat consists of two seats, which are located on both sides of the support seat. The lifting seat contacts the support seat, and the contact surface of the lifting seat is an inclined surface. When the lifting seat moves outward through the inclined surface, it can drive the mop disc to rise on the mop bucket. The lifting seat is also equipped with a counterweight and a reset device. When the mop disc rotates rapidly and generates centrifugal force, the two lifting seats can slide outwards. When the centrifugal force of the mop disc is less than the reset force of the reset device, the two lifting seats can reset.

[0007] This automatic mop disc lifting device uses two inclined lifting seats in conjunction with a support base. When the centrifugal force is greater than the restoring force of the lifting seats, the two lifting seats drive the mop disc upward, causing the existing water supply device to stop supplying water. In this way, the mop disc can be spun dry. The above structure is very simple and reasonable.

[0008] Furthermore, the support base is equipped with elastic support members on both sides that connect to the mop disc. This design is to ensure the lifting base can be reset.

[0009] Furthermore, the elastic support component includes a support rod, a spring seat, and a spring. The support rod has a connecting post, the spring seat is mounted on the mop head, and the spring is positioned between the connecting post and the spring seat. The above design is simple and reasonable.

[0010] Furthermore, a planar bearing is provided at the lower end of the support base, and the planar bearing is fixed to the support base by a bearing seat. The above design further improves the smoothness of the lifting device's rotation.

[0011] Furthermore, a limiting device is provided between the support base and the mop head to prevent the support base from moving. This design makes the device more stable during use.

[0012] Furthermore, the limiting device is a card plate and a card slot, one of which is located on the support base and the other is located on the mop tray.

[0013] Furthermore, the upper end of the lifting seat is also provided with a color sticker part, and the reset device is a reset spring.

[0014] Compared with the prior art, the advantages of this utility model are: the automatic lifting device for the mop tray has a very simple and reasonable structure, and rotates smoothly. Attached Figure Description

[0015] The accompanying drawings illustrate exemplary embodiments of the present disclosure and, together with their description, serve to explain the principles of the disclosure. These drawings are included to provide a further understanding of the disclosure and are incorporated in and constitute a part of this specification. In the drawings: Figure 1 This is a schematic diagram of the structure of an automatic mop tray lifting device according to the present invention.

[0016] Figure 2 This is a schematic diagram of the lifting seat structure described in this utility model.

Spring seat; 8. Sleeve post; 9. Surface bearing; 10. Bearing seat; 11. Slot; 12. Color sticker part. Detailed Implementation

[0018] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., as in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0019] Please refer to Figure 1 and Figure 2 This embodiment provides an automatic mop tray lifting device comprising: a support base 1, a lifting base 3, an elastic support 5, a flat bearing 9, and a bearing seat 10. The support base 1 is cylindrical with a central hole 2 at its center. Two opposing slots 11 are formed on the upper side of the support base 1. The flat bearing 9 is fixed to the lower side of the support base 1 via the bearing seat 10, allowing the support base 1 to rotate smoothly. Two lifting bases 3 are provided, located on opposite sides of the support base 1. Extension rods extend from the two support bases 3 towards each other. The lower end of each extension rod has an inclined surface 4, which slopes upwards from the inside out. The lowest surface of the inclined surface 4 serves as the initial contact surface, fitting against the upper surface of the support base 1. A counterweight is fixed on the aforementioned lifting seat 3. A return spring is also provided between the lifting seat 3 and the mop disc. When the mop disc rotates, the centrifugal force causes the two lifting seats 3 to move outward. When the centrifugal force disappears or is less than the return force, the return spring can reset the seat. The aforementioned support seat 1 has elastic support members 5 connected to the mop disc on both sides. The elastic support member 5 includes a support rod 6, a spring seat 7, and a spring. A sleeve post 8 is fixed on the support rod 6. The spring seat 7 is located on the mop disc. The spring is located between the sleeve post 8 and the spring seat 7. Of course, a card plate is also fixed inside the mop disc and engaged in the slot 11 to prevent the support seat 1 from moving. It is also used to fix the support seat 1 in a movable manner.

[0020] It should be noted that the existing mop head has a locking sleeve inside, which is opposite to the center hole 2. When in use, the locking sleeve locks the rotating shaft of the mop bucket. When the mop head rotates slowly, the water supply mechanism of the mop bucket fills the water, and at the same time the cleaning device cleans the mop cloth. When the user pushes the mop handle up and down quickly, the centrifugal force generated by the mop head causes the two lifting seats 3 to move outward. Due to the action of the inclined plane 4, the lifting seats 3 lift the mop head. At this time, the water supply mechanism stops filling the water, and the mop cloth is spun dry. This step is the same as the function of the existing mop head automatic lifting device.

[0021] As a preferred structure, the upper end of the aforementioned lifting seat 3 is also connected to a colored sticker 12.
