Description
Technical Field
[0001] This application relates to the field of floor scrubbers, and in particular to a wireless charging dock for a handheld floor scrubber. Background Technology
[0002] As people's living standards improve, floor scrubbers have gradually become indispensable household appliances. For ease of use, most existing household floor scrubbers use internal rechargeable batteries and external charging ports to obtain power. This eliminates the need for power cords during use. Handheld floor scrubbers, with their multiple functions including sweeping, scrubbing, and drying, are more popular than smaller robotic vacuum cleaners. A typical handheld floor scrubber includes a control handle, a roller brush, a clean water supply system, a wastewater recycling system, and a storage battery.
[0003] Currently, existing handheld floor scrubbers cannot effectively align with the charging base during charging, making operation inconvenient. Furthermore, the small contact area of the metal contacts on the charging base makes them prone to wear and poses safety hazards. Utility Model Content
[0004] To improve the convenience of charging, this application provides a wireless charging dock for handheld floor scrubbers.
[0005] The wireless charging dock for the handheld floor scrubber provided in this application adopts the following technical solution:
[0006] include:
[0007] Charging base body;
[0008] The docking components are symmetrically arranged on the charging base body and are used to charge the floor scrubber.
[0009] The docking components include:
[0010] The charging head is located on the charging base body;
[0011] The bracket is fixedly mounted on the charging base body, and the charging head is fitted onto the outer wall of the bracket;
[0012] A slider is slidably mounted on the charging head;
[0013] A conductive sheet is fixedly mounted on the slider.
[0014] The first spring is connected at one end to the slider and at the other end to the bracket;
[0015] The charging head has a conical structure, and the slider has a slot for mounting conductive plates.
[0016] By adopting the above technical solution, when the floor scrubber approaches the charging base, the conical charging head facilitates accurate insertion of the scrubber. During this process, the inner wall of the receiving part on the scrubber abuts against the slider. The slider moves downward under the weight of the scrubber, compressing the internal space of the support. A first spring provides support, ensuring precise connection between the conductive plate's contacts and the receiving part of the scrubber, as well as a tight fit between the contact surfaces. This effectively avoids charging failures due to placement errors, improves charging reliability, and increases the contact area, enhancing charging convenience, reliability, and safety. After charging is complete, the scrubber is removed from the charging head, and the slider returns to its normal state under the action of the first spring.
[0017] In one possible implementation, guide blocks are provided at both ends of the slider, and guide grooves that cooperate with the guide blocks are provided on the bracket.
[0018] In one possible implementation, a limiting plate is provided on the bottom of the slider, and a limiting groove that cooperates with the limiting plate is provided on the bracket.
[0019] In one possible implementation, the conductive sheet has protrusions that increase the conductive area.
[0020] In one possible implementation, the bracket is provided with a first limiting post, the slider is provided with a second limiting post, and the two ends of the first spring are respectively sleeved on the first limiting post and the second limiting post.
[0021] In one possible implementation, the charging head has a groove, in which a rubber ring is installed, with one end of the rubber ring abutting against the charging base body.
[0022] In one possible implementation, the charging head is connected to the charging base body by bolts.
[0023] In one possible implementation, the bracket and the charging head are connected by bolts.
[0024] In one possible implementation, the upper end of the slider has an inclined portion.
[0025] In one possible implementation, the upper end of the electric head is provided with a through hole, a locking block is installed in the through hole, a third limiting post is provided on the bracket, a second spring is sleeved on the third limiting post, and one end of the second spring is connected to the locking block.
[0026] In summary, this application includes the following beneficial technical effects: When the floor scrubber approaches the charging base, the conical charging head facilitates accurate insertion of the scrubber. During this process, the inner wall of the receiving part on the scrubber abuts against the slider. The slider moves downward under the weight of the scrubber. Under the force, the slider moves backward under the guidance of the guide groove and the limiting groove, compressing the internal space of the bracket. A certain supporting force from the first spring ensures precise connection between the conductive sheet's contact and the receiving part in the scrubber, as well as a tight fit between the contact surfaces. This effectively avoids charging failures caused by placement deviations, improves charging reliability, and increases the contact area, enhancing the convenience, reliability, and safety of charging. After charging is complete, when the scrubber is removed from the charging head, the slider, under the action of the first spring, pops back out through the guide groove to return to its normal state.

[0037] Reference Figure 1-5 A wireless charging dock for a handheld floor scrubber includes a charging dock body 1 and a docking component 2. The docking component 2 is symmetrically arranged on the charging dock body 1 and is used to charge the floor scrubber. Specifically, the docking component 2 includes a charging head 3, a bracket 4, a slider 5, a conductive sheet 6, and a first spring 7. The charging head 3 has a conical structure and is bolted to the charging dock body 1. The bracket 4 is bolted to the charging dock body 1, and the charging head 3 is fitted onto the outer wall of the bracket 4. The bracket 4 is partially bolted to the charging head 3. The charging head 3 has an opening 8, and the slider 5 is movably installed in the opening 8. The slider 5 has a slot 9, and the conductive sheet 6 is installed in the slot 9. The conductive sheet 6 has a protrusion 10 to increase the conductive area. One end of the first spring 7 is connected to the slider 5, and the other end is connected to the bracket 4. The bracket 4 has a first limiting post 11, and the slider 5 has a second limiting post 12. The two ends of the first spring 7 are respectively fitted onto the first limiting post 11 and the second limiting post 12.
[0038] Guide blocks 13 are provided at both ends of the slider 5, and guide grooves 14 that cooperate with the guide blocks 13 are provided on the bracket 4.
[0039] The bottom of the slider 5 is provided with a limiting plate 15, and the bracket 4 is provided with a limiting groove 16 that cooperates with the limiting plate 15. The limiting plate 15 is inserted into the limiting groove 16 so that the limiting plate 15 can only move within the range of the limiting groove 16.
[0040] The charging head 3 has a groove 17, and a rubber ring 18 is installed in the groove 17. One end of the rubber ring 18 abuts against the charging base body 1.
[0041] The upper end of the slider 5 has an inclined part 19 for easy guidance.
[0042] The charging head 3 has a through hole 20 at its upper end, and a locking block 21 is installed inside the through hole 20. One end of the locking block 21 is chamfered. The bracket 4 has a third limiting post 22, and a second spring 23 is sleeved on the third limiting post 22. One end of the second spring 23 is connected to the locking block 21. When the floor scrubber is inserted into the charging head 3, the locking block 21 secures the floor scrubber, improving its stability during charging. The chamfered end of the locking block 21 facilitates the removal of the floor scrubber.
[0043] The operation process is as follows: When the floor scrubber approaches the charging base 1, the conical charging head 3 facilitates accurate insertion of the floor scrubber. During this process, the inner wall of the receiving part on the floor scrubber abuts against the slider 5. The slider 5 moves inward due to the weight of the floor scrubber. Under the force, the slider 5 moves backward under the guidance of the guide groove 14 and the limiting groove 16, compressing the internal space of the bracket 4. Then, the first spring 7 provides a certain force to ensure that the contact of the conductive sheet 6 is accurately connected with the receiving part in the floor scrubber and that the contact surface is tightly fitted. This effectively avoids charging failure caused by placement deviation, improves charging reliability, and increases the contact area, improving the convenience, reliability, and safety of charging. After charging is completed, the floor scrubber is removed from the charging head 3, and the slider 5, under the action of the first spring 7, pops out again through the guide groove 14 to return to its normal state.
