Description

Technical Field

[0001] This invention relates to the field of household goods technology, specifically a retractable, labor-saving mop. Background Technology

[0002] As a basic and essential cleaning tool, the development history of the mop is closely linked to humanity's pursuit of a hygienic living environment. From its initial simple form to today's diverse and professional products, the technological evolution of the mop reflects advancements in materials science, ergonomics, and cleaning concepts. As a manual floor cleaning tool, the technological development of the mop revolves around three core issues: cleaning efficiency, ease of use, and hygiene. Early forms often employed a fixed structure, where a long handle was permanently connected to a mop head made of natural absorbent materials such as cloth strips, cotton thread, or sponge.

[0003] Early mops had a relatively simple structure, typically consisting of a long handle and a bundle of absorbent material. While these traditional mops were inexpensive, they had significant drawbacks in use. Cleaning required the user to wring them out forcefully, a laborious and unhygienic process. Existing flat mops required both hands to operate, especially when squeezing out the internal water, which was time-consuming and laborious. Furthermore, existing mops still had areas for improvement in terms of usability. Therefore, those skilled in the art have provided a retractable, labor-saving mop to address the problems mentioned in the background section. Summary of the Invention

[0016] (III) Beneficial Effects

[0017] This invention provides a retractable, labor-saving mop. It has the following beneficial effects:

[0018] 1. In this invention, by setting an adjustment structure, when in use, pressing the positioning block causes the positioning block to slide the circular plate downward inside the telescopic rod, while compressing the first spring. Under the action of the two first connecting rods, the opening structure is opened to both sides. When squeezing out water, by pushing the positioning block to one side, the first spring is released from its restriction and quickly springs upward. Then, by manually pulling the push plate, the two through slots at the upper end are compressed. Under the action of the connecting rope, the first spring is pulled upward. Under the action of the opening structure, the water inside is squeezed and dehydrated. This allows for operation with one hand, saving time and effort, and also has a certain degree of playability.

[0019] 2. In this invention, by setting up a spreading structure, two movable connecting rods and two movable connecting seats are movably connected to two second connecting rods. Combined with the movable connection relationship between two vertical plates and two connecting slots, the two flat plates can be folded. Through the rotational connection of four connecting shafts and four torsion springs, the two flat plates can be assisted in folding and spreading, making it smoother and more labor-saving when used in conjunction with the adjustment structure.

[0020] 3. In this invention, by setting an extended structure, when in use, pressing the pressing plate drives the third spring to press down the limiting block on the upper surface of the second absorbent block, causing the limiting block to be pressed out from the inside of the movable hole. After being pressed out, under the elastic action of the two second springs inside the two second sliding grooves, the two sliders are pushed outward, simultaneously causing the second absorbent block to extend outward by a distance, and the connecting cloth is also unfolded. This can prevent dust from accumulating between the second absorbent block and the first absorbent block, increasing the usable area of ​​the mop. It is more labor-saving when used on large areas of the floor. When storing, the second absorbent block is pushed back, so that the limiting block is re-engaged inside the movable hole.

[0037] Example 2: Suitable for use on large ground areas;

[0038] In use, pressing the pressing plate 407 causes the third spring 412 to press down on the limiting block 411 on the upper surface of the second absorbent block 402, thus pressing the limiting block 411 out of the movable hole 413. After being pressed out, the two sliders 406 are pushed outward by the elastic action of the two second springs 405 inside the two second sliding grooves 403, which in turn causes the second absorbent block 402 to extend outward a certain distance.

It is more labor-saving when used on large areas of the floor. When storing, the second absorbent block 402 is pushed back, so that the limiting block 411 is re-engaged inside the movable hole 413.

[0039] Working principle: This application is a telescopic labor-saving mop. When in use, pressing the positioning block 205 causes the positioning block 205 to drive the circular plate 213 to slide downward inside the telescopic rod 1, while compressing the first spring 212. Under the action of the two first connecting rods 209, the opening structure 3 is opened to both sides. When squeezing out water, by pushing the positioning block 205 to one side, the first spring 212 is released from its restriction and quickly springs upward. Then, by manually pulling the push plate 203, the two through slots 211 at the upper end are compressed. Under the action of the connecting rope 210, the first spring 212 is pulled upward. Under the action of the opening structure 3, the water inside is squeezed out. It can be operated with one hand, saving time and effort and also has a certain degree of playability.

[0040] Two movable connecting rods 304 and two movable connecting seats 302 are movably connected to two second connecting rods 305. Combined with the movable connection between two vertical plates 306 and two connecting slots 309, the two flat plates 303 can be folded. Through the rotational connection between four connecting shafts 307 and four torsion springs 308, the two flat plates 303 can be folded and spread out, making it smoother and less strenuous when used in conjunction with the adjustment structure 2.

[0041] By pressing the pressing plate 407, the pressing plate 407 drives the third spring 412 to press down the limiting block 411 on the upper surface of the second absorbent block 402, so that the limiting block 411 is pressed out from the inside of the movable hole 413. After being pressed out, under the elastic action of the two second springs 405 inside the two second sliding grooves 403, the two sliders 406 are pushed outward, and at the same time, the second absorbent block 402 is extended outward by a certain distance. The connecting cloth 404 is also unfolded, which can prevent dust from accumulating between the second absorbent block 402 and the first absorbent block 401, and increase the usable area of ​​the mop. It is more labor-saving when used on large areas of the floor. When storing, the second absorbent block 402 is pushed back, so that the limiting block 411 is re-engaged inside the movable hole 413.
