Description

Technical Field

[0001] The present application relates to the field of factory cleaning, and in particular to a foldable wall cleaning device. Background Art

[0002] In the production process of pharmaceutical companies, following Good Manufacturing Practice (GMP) is a key factor in ensuring the quality and safety of drugs. GMP standards cover a wide range of aspects, one of which is to strictly implement 5S management (sorting, organizing, cleaning, and quality control) on the production site to maintain a high standard of hygiene and order in the production environment.

[0003] Cleaning is a crucial part of 5S management, requiring staff to follow specific standard operating procedures (SOP), including ensuring that the return air window of the return air vent is fully opened to allow air circulation before starting cleaning work, and using a mercerized towel to thoroughly clean the return air vent floor and the surrounding walls. Such measures are intended to remove dust and particles that may accumulate, thereby reducing the risk of contamination in the production area.

[0004] However, there are certain challenges in cleaning work. Since the internal space of the return air vent is relatively large and located at a low position, cleaning staff often need to bend or squat when performing cleaning tasks, which not only increases the difficulty of the work, but also puts a certain amount of pressure on the employees' bodies. Especially considering that employees may be limited by age, health conditions or other personal factors, this physical requirement makes cleaning work more arduous. Summary of the invention

[0005] The purpose of the present application is to provide a foldable wall cleaning device that can effectively and conveniently clean the internal space of the return air vent.

[0006] The present application discloses a foldable wall cleaning device, comprising: a cleaning head 1, a connecting portion 2 and a hand-held rod 3;

[0007] The connecting portion 2 includes a pivot structure, which is installed between the cleaning head 1 and the hand-held rod 3, and is configured to allow the cleaning head 1 to rotate 360 ​​degrees in the horizontal and vertical planes. The pivot structure includes: a rotating seat 21 fixed to the lower end of the hand-held rod 3 and a universal joint 22 fixed to the upper surface of the cleaning head 1, and the universal joint 22 extends into the rotating seat 21 to form a fit;

[0008] The upper surface of the cleaning head 1 is provided with a groove 4 parallel to its edge, wherein the inner wall of the groove 4 is provided with an elastic member, and the elastic member is configured to accommodate and clamp the edge of the cleaning towel;

[0009] The hand-held rod 3 includes multiple sections of the rod body 31, and one end of each section of the rod body 31 is provided with a hand-held rod 3 connecting piece for connecting with another section of the rod body 31. A hinge device is provided between each section of the rod body 31, and the hinge device is configured to allow two adjacent sections of the rod body 31 to be folded and unfolded within a preset angle range.

[0010] In a preferred example, the multi-section rod body 31 is configured to form a straight rod after being fully unfolded.

[0011] In a preferred example, a handle 32 is provided at the upper end of the hand-held rod 3, and a hanging hole 33 is provided at the upper end of the handle 32. The hanging hole 33 is configured to allow the wall cleaning device to be hung in cooperation with a hook.

[0012] In a preferred example, the universal joint 22 includes a spherical joint, the rotating seat 21 is provided with a spherical groove, and the spherical joint and the spherical groove cooperate with each other.

[0013] In a preferred example, the hinge device includes at least one rotating shaft fixed on a section of the rod body 31 and at least one corresponding receiving hole arranged on the corresponding rod body 31, and the rotating shaft and the receiving hole cooperate to realize the folding and unfolding of the rod body 31.

[0014] In a preferred embodiment, a plurality of through holes are evenly distributed between the upper surface and the bottom surface of the cleaning head 1 .

[0015] In a preferred example, the length of the hand-held rod 3 after being folded is 30-50 cm, and the length of the hand-held rod 3 after being unfolded is 100-150 cm.

[0016] In a preferred example, the width of the cleaning head 1 is 15 cm-30 cm.

[0017] In a preferred example, the hand-held rod 3 includes 3-5 sections of the rod body 31.

[0018] In a preferred embodiment, the cleaning head 1 has a thickness of 1-4 cm.

[0019] In the embodiment of the present application, a pivot structure is provided between the cleaning head and the hand-held rod, so that the cleaning head can rotate 360 ​​degrees in a horizontal or vertical plane, which greatly improves the flexibility of cleaning and makes the mop particularly suitable for cleaning hard-to-reach areas such as the return air vents of pharmaceutical factories. The staff can easily adjust the angle of the mop to thoroughly clean the inside and outside of the return air vents to ensure that the environmental hygiene standards of the clean room are maintained, thereby meeting the requirements of good manufacturing practices (GMP). In addition, the mop head is provided with a groove, and the elastic member in the groove can accommodate various types of cleaning towels. For pharmaceutical factories, especially in production areas and clean rooms, where high standards of cleaning and disinfection are required, using a mop with cleaning towels that can be replaced at any time can reduce the risk of cross contamination and ensure the safety of drug production. The hand-held rod is designed as a foldable multi-section rod structure, which can be folded for easy storage and carrying.

[0042] In order to better understand the technical solution of the present application, a specific example is provided below for illustration. The details listed in the example are mainly for ease of understanding and are not intended to limit the scope of protection of the present application.

[0043] When cleaning, the cleaning staff of the pharmaceutical factory can open the folded hand-held rod 3 to make the hand-held rod 3 a straight rod. The hinged device between each section of the rod body 31 of the hand-held rod 3 can be fixed at any angle due to the friction on its surface. The cleaning staff can adjust the hand-held rod 3 according to the height and the specific needs of the cleaning area. The cleaning head 1 is designed to be able to rotate 360 ​​degrees at will. It is connected to the hand-held rod 3 through a pivot structure. The cleaning staff can easily adjust the direction of the cleaning head 1 to adapt to the irregular shape and position of the return air outlet. Whether cleaning the inside of the return air outlet or the walls around it, comprehensive cleaning can be achieved by simply adjusting the angle of the wrist without moving the foothold or using additional tools.

[0044] In order to further improve the cleaning efficiency, a groove 4 is provided on the cleaning head 1 to clamp different types of cleaning towels, such as mercerized towels or microfiber cloths. When cleaning is completed or the cleaning towel is too dirty and needs to be replaced, it is only necessary to pull the cleaning towel out of the groove 4, thus ensuring that clean materials are used for each cleaning.

[0045] After finishing cleaning, the cleaning staff can fold up the multi-section rod body 31 of the hand-held rod 3, which greatly saves storage space or makes it convenient for the cleaning staff to carry the mop to the next cleaning area.
