Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and more specifically, to a multifunctional cleaning sponge. Background Art

[0002] Vacuum and water absorber, as a dual-purpose wet and dry cleaning equipment, can absorb both dust and water. It is currently widely used in hotels, offices, factories, exhibition halls, homes and other occasions. It is easy to use, can absorb dust or water thoroughly, is economical and has stable performance.

[0003] The vacuum cleaner is equipped with a fan and a centrifugal chamber. After the power is turned on, the fan blades rotate at high speed, causing the air to be discharged at high speed, and the air at the front end of the fan is continuously sucked into the fan, causing an instantaneous vacuum inside the vacuum cleaner, forming a negative pressure difference with the outside world. Under the action of the negative pressure difference, the vacuum cleaner uses suction to suck away dust or sewage from floors, carpets, walls, furniture and other surfaces that are difficult to remove dirt. When dust, air and water are sucked into the centrifugal chamber, the heavier water is rotated at high speed and thrown to the inner wall of the centrifugal chamber and then flows into the water collection bucket below, while the lighter dust and air will enter the filter bag to filter the dust after passing through the centrifugal chamber. After filtering and separation, clean air is discharged. It can be seen that whether it is vacuuming or absorbing water, the vacuum cleaner is based on the same principle and operation.

[0004] However, the vacuum scraper and water squeegee of the vacuum and water suction machine commonly used in the market are configured separately, and the vacuum scraper and water squeegee are integrally formed structures. The vacuum scraper is installed and used when vacuuming, and the vacuum scraper is removed and the water squeegee is installed when water is needed. Since the vacuum scraper and the water squeegee are mostly connected to the suction pipe of the vacuum and water suction machine through threads, the thread structure is complicated to process, and the disassembly and assembly is time-consuming and labor-intensive, which is inconvenient. In addition, the vacuum scraper and the water squeegee each contain many parts and are large in size, and storing them when not in use also takes up a lot of space.

[0005] Therefore, it is necessary to propose a multifunctional cleaning spatula that solves the above problems. Summary of the invention

[0006] The multifunctional cleaning scraper provided by the present invention is mainly used to solve the problem that the common vacuum and water suction machines on the market are all equipped with a vacuum scraper and a water suction scraper separately, and the vacuum scraper and the water suction scraper are integrally formed structures, which are time-consuming and laborious to disassemble and assemble when replaced and used, and there are many inconveniences, and the vacuum scraper and the water suction scraper have complex structures and large volumes, and they take up a lot of space when stored. The scraper seat of the multifunctional cleaning scraper of the present invention can be universal, and by replacing and installing the vacuum brush strip and the water suction rubber strip on the scraper seat, the dust suction and water suction functions can be switched, thereby giving full play to the dry and wet dual-purpose functions of the vacuum and water suction machine.

[0007] In order to solve the above technical problems, the technical solutions adopted by the present invention are as follows:

[0008] A multifunctional cleaning scraper, used for a vacuum and water absorbing machine, the multifunctional cleaning scraper comprises a scraper seat, a fixing pressure strip, a vacuum brush strip and a water absorbing rubber strip;

[0009] The scraper seat is provided with an installation cavity with an open bottom, the scraper seat and the fixed pressure strip can be used interchangeably, the dust suction brush strip and the water absorption rubber strip can be installed replaceably in the installation cavity, thereby forming a dust suction scraper or a water absorption scraper, which is easy to disassemble and replace, and can easily realize the conversion of dust suction and water absorption functions;

[0010] The fixed pressure strip is provided with a central through hole, and mounting holes are symmetrically provided at both ends of the fixed pressure strip. The inner side of the mounting cavity is provided with fixing holes corresponding to the mounting holes. The fixed pressure strip can be embedded and fixed in the mounting cavity through the mounting holes and the fixing holes. The fixed pressure strip is used to press and fix the vacuum brush strip or the water-absorbing rubber strip in the mounting cavity.

[0011] Furthermore, the vacuum brush bar includes a first brush bar and a second brush bar, both of which are assembled from densely arranged bristles; the first brush bar and the second brush bar are fixedly installed on the front and rear sides of the installation cavity through the fixed pressure strip, respectively, and the first brush bar and the second brush bar are vertically parallel to each other, thereby forming a vacuum scraper for the vacuum suction machine. The densely arranged bristles of the first brush bar and the second brush bar are soft and wear-resistant, and can be applied to floors and carpets in various places, and can sweep and vacuum thoroughly without leaving any marks.

[0012] Furthermore, the top of the fixed pressure strip is symmetrically provided with strip grooves on both sides along its length, and the strip grooves are respectively provided with installation slots between the front and rear side walls of the installation cavity; the tops of the first brush strip and the second brush strip are respectively provided with installation clips that are engaged with the installation slots; the installation slots and the installation clips have the same longitudinal cross-sectional shape and size. In this way, under the pressing force of the fixed pressure strip, the installation clips of the first brush strip and the second brush strip are respectively clamped and fixed in the installation slots, so that the vacuum brush strip is assembled and fixed to the pick-up seat, which is stable and reliable, not easy to fall off, and safe to use.

[0013] Furthermore, a plurality of square notches are arranged at intervals on the first brush strip. The purpose of providing the square notches is to facilitate the vacuum cleaner to remove large particles of dust, paper scraps, cigarette butts, hair and other debris during vacuuming, so that the cleaning effect is clean and thorough.

[0014] Furthermore, the water-absorbing rubber strip includes a first rubber strip, a second rubber strip, and a connecting rib used to connect the first rubber strip and the second rubber strip, the first rubber strip and the second rubber strip are vertically parallel to each other, the connecting rib is horizontally arranged relative to the first rubber strip and the second rubber strip, and the longitudinal cross-section of the water-absorbing rubber strip is "n"-shaped; the connecting rib of the water-absorbing rubber strip is fixed in the installation cavity through the fixing strip, so that the first rubber strip and the second rubber strip are assembled and fixed to the squeegee seat to form a water squeegee for a vacuum cleaner. The first rubber strip and the second rubber strip are preferably made of rubber material, with soft texture, good toughness and elasticity, suitable for floors in various occasions, can effectively protect floor tiles or floors from being scratched, and can scrape and absorb water cleanly and thoroughly, with good cleaning effect.

[0015] Furthermore, the sides of the central through hole on the fixed pressure strip protrude relative to the top sides of the two ends of the fixed pressure strip; the connecting rib is provided with a through groove corresponding to the central through hole. In this way, when installing the water-absorbing rubber strip, the connecting rib is sleeved on the upper part of the fixed pressure strip through the through groove, and the protruding side of the central through hole penetrates and is exposed at the upper part of the through groove, which can play a role in limiting and fixing the connecting rib. The first rubber strip and the second rubber strip hang vertically from the front and rear sides of the fixed pressure strip respectively, and the fixing pressure strip is fixedly connected to the pick by screws penetrating the installation hole and the fixing hole, and the water-absorbing rubber strip completes the fixed assembly.

[0016] Furthermore, the two ends of the first rubber strip and the two ends of the second rubber strip are respectively bent and brought together, so that the two ends of the water-absorbing rubber strip are formed with avoidance holes corresponding to the installation hole and the fixing hole. This can prevent air leakage in the gap between the first rubber strip and the second rubber strip, which leads to a decrease in the suction force during water absorption, and ensure assembly coordination. When the fixing strip and the bracket are installed and fixed, the avoidance holes can ensure that the screws can smoothly pass through the water-absorbing rubber strip without piercing and damaging its connecting ribs.

[0017] Furthermore, the first rubber strip, the second rubber strip and the connecting ribs are an integrally formed structure, which is easy to process and manufacture, has good structural strength, is easy to install, and is not prone to deformation or separation and falling after installation.

[0018] Furthermore, the outer side surface of the bottom end of each of the first rubber strip and the second rubber strip is a corrugated surface, which can not only increase the contact area with water and ensure that the water is evenly scraped and cleanly absorbed during water absorption, but also improve the aesthetic appearance of the water-absorbing rubber strip.

[0019] Further preferably, a connecting pipe is provided on the upper portion of the pick seat, and a mounting joint is provided on the connecting pipe. The mounting cavity of the pick seat is interconnected with the connecting pipe and the interior of the mounting joint. The mounting joint is used to fix the hand-held suction pipe of the vacuum cleaner and water suction machine.
