Description

Technical Field

[0001] This utility model belongs to the field of mop buckets, specifically a split impeller for mop buckets. Background Technology

[0002] In the field of mop cleaning equipment, the mop bucket water inlet impeller is the core component that enables automatic water filling and cleaning of the mop disc. Its structural design directly affects the ease of use, transportation costs, and cleaning effect of the mop bucket. In existing technologies, mop bucket impellers generally adopt an integrated molding design. This impeller assembly includes an impeller seat, impeller blades, a bearing, a rotating shaft, and a snap-fit ​​connector. The impeller seat has a typical trumpet-shaped structure, with a larger diameter at the lower end and a smaller diameter at the upper end. Several impeller blades are circumferentially fixed to the lower end of the impeller seat for water filling during rotation. A bearing is coaxially mounted inside the impeller seat, and a rotating shaft is fixedly fitted inside the bearing's inner ring. The lower end of the rotating shaft is vertically fixed inside the mop bucket body. Through the cooperation of the bearing and the impeller seat, the impeller seat rotates relative to the rotating shaft. The upper end of the rotating shaft extends upwards through the upper surface of the impeller seat, and the diameter of this upper end is smaller than the diameter of the upper end of the impeller seat. Simultaneously, a snap-fit ​​connector is fixedly mounted on the upper end of the impeller seat for detachable engagement with the mop head. Thus, the rotation of the impeller seat drives the mop head to rotate synchronously, completing the cleaning operation. However, the above-mentioned existing water impeller structure has the following significant technical defects in practical applications: Firstly, the integrated structural design has poor adaptability, making it inconvenient to transport foldable mop buckets. With the development of portable home cleaning equipment, foldable mop buckets have been widely used due to their advantages of small storage space and easy carrying. However, the existing water inlet impeller is a one-piece molded structure. Its flared impeller seat and integrated assembly structure result in a large overall size of the impeller, which cannot be disassembled or folded. Even after the foldable mop bucket is folded, this integrated impeller still occupies a large space, which not only reduces the compactness of the folded mop bucket, but also increases the packaging volume and transportation costs during transportation, seriously affecting the transportation efficiency and market applicability of foldable mop buckets. Secondly, the upper end of the rotating shaft cannot rotate independently, which obstructs the rotation of the mop disc and affects the cleaning effect. In the existing structure, the rotating shaft is fixedly engaged with the impeller seat through a bearing, and the upper end of the rotating shaft is relatively fixed to the impeller seat. It can only rotate around the axis of the rotating shaft along with the impeller seat as a whole, and cannot achieve independent rotation of the upper end of the rotating shaft relative to the impeller seat. When the mop disc is snapped onto the connector, the rotation of the mop disc depends entirely on the drive of the impeller seat. However, in the actual cleaning process, the mop disc needs to be flexibly rotated and adjusted according to the condition of the cleaning surface. The fixed constraint relationship between the upper end of the rotating shaft and the impeller seat in the existing structure restricts the degree of freedom of rotation of the mop disc, which easily leads to jamming and uneven rotation. This not only increases the resistance of the cleaning operation, but also causes uneven force on the cleaning surface, reducing cleaning efficiency and cleaning effect. Utility Model Content

[0003] In view of the defects of the existing water inlet impellers used in mop trays, the technical problem to be solved by this utility model is that the existing integrated structure of the mop bucket water inlet impeller has obvious deficiencies in adapting to the transportation needs of foldable mop buckets and ensuring the flexible rotation of the mop tray. It is urgent to improve its structure to solve the above-mentioned technical defects.

[0004] To achieve the above objectives, according to one aspect of this utility model, the present utility model is implemented through the following technical measures: a split-type impeller for a mop bucket, comprising: an impeller body and a rotating shaft, wherein a bearing is provided in the impeller body, and the rotating shaft is inserted into the bearing to enable the impeller body to rotate. The impeller body consists of an upper rotating part and a lower impeller part. The lower impeller section is equipped with a bearing, and the upper rotating part can be separated from the lower impeller section. The upper end of the rotating shaft extends into an upper rotating part, and the upper end of the upper rotating part is provided with a locking part for locking and fixing the mop.

[0005] Furthermore, the lower end of the impeller body extends from the lower side of the rotating shaft and is inserted and fixed to the mop bucket.

[0006] Furthermore, the rotating shaft is composed of an upper shaft body and a lower shaft body. The lower shaft body is inserted into a bearing in the lower impeller section, and the upper shaft body is located on the upper rotating part. The upper shaft body and the lower shaft body do not contact each other.

[0007] Furthermore, the upper rotating part and the lower impeller part are threadedly connected, and the lower end of the lower impeller part is provided with a plug hole, and a ball is provided in the plug hole, the ball being for the upper end of the lower shaft to contact.

[0008] Furthermore, the upper rotating part is provided with a plug-in shaft hole at its upper end, the plug-in shaft hole is for the upper shaft body to be plugged in, and the plug-in shaft hole and the upper shaft body are limited by a slot and a retaining ring that is locked in the slot, so that the upper shaft body can rotate.

[0009] Furthermore, the retaining ring is disposed on the upper shaft, and the upper shaft is provided with multiple retaining rings spaced vertically apart.

[0010] Compared with the prior art, the advantages of this utility model are: 1. This split impeller breaks through the structural limitations of existing integrated impellers by separating the impeller body into a threaded upper rotating part and a lower impeller part. During transportation or storage, the upper rotating part and the lower impeller part can be separated, significantly reducing the overall volume occupied by the impeller. This allows the foldable mop bucket to achieve a more compact storage state after folding, effectively reducing packaging space requirements; at the same time, it reduces the loading volume during transportation, lowers logistics costs, and significantly improves the transportation efficiency and market adaptability of the foldable mop bucket. 2. By designing the rotating shaft as a non-contact upper and lower shaft, and with the upper shaft being assembled to the upper rotating part through insertion holes with multiple sets of spaced retaining rings and able to rotate freely, the problem of the existing rotating shaft being fixed to the impeller seat and unable to rotate independently is solved. When the mop disc is engaged with the engaging part of the upper rotating part, the upper shaft can drive the mop disc to rotate independently of the lower impeller (and lower shaft), allowing the mop disc to flexibly adjust the rotation angle and speed according to the cleaning surface, avoiding problems such as jamming and uneven rotation; this reduces cleaning resistance and ensures even force on the cleaning surface, significantly improving cleaning efficiency and cleaning effect.

[0011] 3. The ball bearings in the insertion hole at the lower end of the lower impeller contact the upper end of the lower shaft, which converts the sliding friction of the lower shaft rotation into rolling friction, reducing component wear and improving the smoothness of the fit between the lower impeller and the lower shaft, as well as the service life of the structure. Meanwhile, the multiple sets of retaining rings spaced vertically on the upper shaft can not only achieve stable positioning of the upper shaft by engaging with the grooves in the insertion shaft hole, but also adjust the assembly height of the upper shaft according to the assembly requirements of the mop disc, adapting to the snap-fit ​​requirements of different specifications of mop discs, and improving the overall versatility and structural adaptability of the impeller.

[0016] 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.

[0017] Please refer to Figures 1-3 This embodiment provides a split impeller for a mop bucket, comprising: an impeller body 1 and a rotating shaft 2. The impeller body 1 consists of an upper rotating part 3 and a lower impeller part 4, which are threaded together to allow separation. The lower impeller part 4 has a flared lower end and a ring of impeller blades on the upper side of the flared end. The lower impeller part 4 has a hollow bottom opening and a bearing is fixed inside. The rotating shaft 2 consists of an upper shaft body 6 and a lower shaft body 7, which is inserted into the bearing. The lower end of the lower shaft body 7 extends out of the lower impeller part 4 and is fixed to the mop bucket. Body 1 can rotate via bearings. The upper end of the lower shaft 7 extends to the upper side of the lower impeller part 4. The lower side of the upper rotating part 3 is machined with a insertion hole, and a rolling ball 8 is provided in the insertion hole. When the upper rotating part 3 and the lower impeller part 4 are screwed together, the upper end of the lower shaft 7 contacts the ball 8. The upper end of the upper rotating part 3 forms a snap-fit ​​part 5, which is fixed by several snap-fit ​​pieces for the mop disc to snap into and drive the impeller body 1 to rotate. At the same time, the upper end of the upper rotating part 3 is also machined with a snap-fit ​​shaft hole for the upper shaft 6 to be inserted into. The snap-fit ​​shaft hole and the upper shaft 6 are limited by a slot and a retaining ring 9 snapped in the slot, so that the upper shaft 6 can rotate.

[0018] Through the above structural design, by splitting the impeller body 1 into an upper rotating part 3 and a lower impeller part 4 that can be threadedly connected, the structural limitation of the existing integrated impeller that cannot be separated is broken. During transportation or storage, the upper rotating part 3 and the lower impeller part 4 can be separated, which greatly reduces the overall volume occupied by the impeller. This allows the foldable mop bucket to achieve a more compact storage state after folding, effectively reducing the packaging space requirements. At the same time, it reduces the loading volume during transportation, lowers logistics costs, and significantly improves the transportation efficiency and market adaptability of the foldable mop bucket.

[0019] As a preferred structure, the aforementioned retaining ring 9 is provided on the upper shaft body 6, and the upper shaft body 6 is provided with multiple retaining rings 9 spaced apart vertically. This design allows the depth of the upper shaft body 6 inserted into the insertion shaft hole to be adjusted.
