Description

Technical Field

[0001] This invention relates to the field of handheld floor scrubber technology, and more particularly to a handheld floor scrubber with a handle for lifting assistance. Background Technology

[0002] Handheld floor scrubbers are a type of floor cleaning device with a wide range of applications, including homes, hospitals, shopping malls, and hotels. They can be categorized into small floor scrubbers, automatic floor scrubbers, and multi-functional floor scrubbers, with the type chosen depending on the application. They feature floor cleaning and wastewater recovery functions. Clean water flows from the clean water tank to the brush plate, where the brushes or pads create friction against the floor, achieving a cleaning effect. A squeegee collects the wastewater, which is then sucked into a wastewater tank by the wastewater recovery system.

[0003] Traditional handheld floor scrubbers lack a lifting mechanism at the rotating connection between the upper and lower brushing devices. When the clean water and wastewater tanks are full, the upper part of the device becomes quite heavy. This puts significant strain on the user's arms during prolonged operation, leading to arm pain and a less than ideal user experience. Therefore, we propose a handheld floor scrubber with a handle for lifting assistance to address these issues. Summary of the Invention

[0004] The present invention proposes a handheld floor scrubber with a handle for assisted lifting, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A rotating component is provided at the connection between the water tank operating component and the floor brushing component to assist in lifting the water tank operating component during use. The rotating component includes a central rotating shaft, a rotating block, a fixed frame, a movable pin, and a torsion spring. The central rotating shaft, movable pin, and torsion spring work together to utilize the torque of the torsion spring to rotate and assist in lifting the water tank operating component above the rotating component. The movable pin controls the release of the torsion spring torque. A mounting bracket is installed on the floor brushing component.

[0007] As a further aspect of the present invention: the water tank operating assembly includes an operating handle, a control device is connected to the operating handle, an operating panel is provided at the upper end of the control device, and a main rod is installed at the bottom of the control device.

A locking block is movably connected to the slot, and the locking block is installed on the side of the base near the clean water tank.

[0015] As a further aspect of the present invention, magnets are respectively provided inside the card slot and the card block.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. This device, through the coordinated use of a rotating central shaft, rotating block, fixed frame, movable pin, torsion spring, connecting block, and brush plate power unit, is used to fix one corner of the torsion spring by moving the movable pin during equipment operation.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Reference Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a handheld floor scrubber with handle-assisted lifting, including a water tank operating component 1 and a floor brushing component 2 at its lower end. A rotating component 3 is provided at the connection between the water tank operating component 1 and the floor brushing component 2 for assisting in lifting the water tank operating component 1 during use. The rotating component 3 includes a central shaft 301, a rotating block 302, a fixed frame 303, a movable pin 304, and a torsion spring 305. The central shaft 301, movable pin 304, and torsion spring 305 work together to utilize the torque of the torsion spring 305 to rotate and assist in lifting the water tank operating component 1 above the rotating component 3. Component 1 is designed to prevent arm pain caused by the weight of the water tank operation component 1 during prolonged operation, making it more convenient for users, improving user experience, reducing arm strain, and making the device more time-saving and labor-saving. The movable pin 304 is used to control the release of torque from the torsion spring 305. The brush assembly 2 is equipped with a mounting bracket 4, which is installed on the outside of the brush power unit 201 near the sewage tank 104. The mounting bracket 4 has pulleys 5 installed at both ends, which are used to place and move the entire device when the brush assembly 2 is folded and not in use.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, the water tank operation assembly 1 includes an operation handle 101 for easy movement of the device by the user. A control device 103 is connected to the operation handle 101. An operation panel 102 is provided on the upper end of the control device 103. The control panel 102 is used in conjunction with the control device 103 to control the operation of the entire device. A main rod 107 is installed at the bottom of the control device 103. A wastewater tank 104 is installed on one side of the main rod 107 to collect wastewater after floor cleaning. A clean water tank 105 is installed on the other side of the main rod 107 to hold clean water. A cleaning liquid tank 108 is provided below one side of the clean water tank 105 to hold cleaning liquid for floor cleaning. A base 109 is installed at the lower end of the wastewater tank 104, the clean water tank 105, and the main rod 107 for mounting the clean water tank 105 and the wastewater tank 104. A connecting block 106 is installed at the bottom of the base 109 for connecting to the rotating assembly 3. The lower end of the connecting block 106 is movably connected to the upper end of the rotating block 302.

[0030] like Figure 1 and Figures 3-6As shown, the rotating block 302 and the torsion spring 305 are movably sleeved on the outside of the rotating central shaft 301. One upper end of the torsion spring 305 is connected to the rotating block 302. The rotating central shaft 301 is mounted through the fixed frame 303. A movable pin 304 is movably connected through the fixed frame 303 below the rotating central shaft 301. One end of the movable pin 304 is in movable limiting contact with the lower end of the torsion spring 305. By pushing the movable pin 304 to one side of the lower end of the torsion spring 305, one end of the movable pin 304 is locked onto one side of the torsion spring 305, thus fixing that end of the torsion spring 305. When the device is in use, the user controls the tilt of the water tank operating component 1 by holding the operating handle 101. The torque of the torsion spring 305, in conjunction with the rotating block 302 and the connecting block 106, assists in lifting the water tank operating component 1. This prevents the user from experiencing arm pain due to the weight of the water tank operating component 1 when the clean water tank 105 or the wastewater tank 104 is full during prolonged operation. The device is convenient for the user, easy to operate, improves the user experience, reduces the strain on the user's arms, and saves time and effort.

[0031] like Figure 1 , Figure 2 , Figure 3 As shown, the floor brush assembly 2 includes a brush plate power unit 201, which controls the brush plate 202 to rotate, clean the floor, and controls the sewage in the squeegee 203 to be transported to the sewage tank 104. Two brush plates 202 are arranged below the brush plate power unit 201. A squeegee 203 is arranged on one side of the two brush plates 202, which is used to suck up the sewage on the ground and transport it to the sewage tank 104 under the action of the brush plate power unit 201, and to scrape the sewage on the ground. The other two ends of the squeegee 203 are respectively provided with squeegee head guide wheels 204 to guide the squeegee 203. A fixing frame 303 is installed on the brush plate power unit 201. A connecting pipe 6 is installed between the brush plate power unit 201 and the base 109 for transporting clean water and sewage.

[0032] like Figure 2 and Figure 3 As shown, the other end of the brush power unit 201 is provided with a handle 7, which is used to control the brush assembly 2 to fold or fold in contact. A slot 8 is provided on the brush power unit 201 above the handle 7. A block 9 is movably connected to the slot 8. The block 9 is installed on the side of the base 109 near the clean water tank 105. Magnets are provided inside the slot 8 and the block 9 respectively, which are used to magnetically position and connect the slot 8 and the block 9 to prevent the block 9 from falling out of the slot 8 at will.

[0033] The working principle of this invention is as follows: When using the device, first place the floor brush assembly 2 on the ground, push the movable pin 304 towards the lower end of the torsion spring 305, so that one end of the movable pin 304 is engaged with that end of the torsion spring 305, thus fixing that end of the torsion spring 305. The user can then hold the operating handle 101 to tilt the water tank operating assembly 1. Through the torque of the torsion spring 305, in conjunction with the rotating block 302 and the connecting block 106, the water tank operating assembly 1 is assisted in being lifted, preventing the water tank operating assembly from being overfilled due to the full water level in the clean water tank 105 or the wastewater tank 104 during prolonged operation. 1. The overall weight can cause arm pain. To make it more convenient for users, the operation is simple and the user experience is improved. It reduces the force on the user's arms and reduces the burden on the user's arms. The device is more labor-saving. Then, the device can be started and operated by controlling the operation panel 102. The brush plate 202 is rotated by the brush plate power device 201. At the same time, the cleaning liquid in the cleaning liquid tank 108 is sprayed onto the ground. The ground is cleaned by the brush plate 202 and the clean water tank 105. Then, the squeegee 203 works in conjunction with the brush plate power device 201 to collect the sewage into the sewage tank 104.

[0034] After the operation is completed, pull the movable pin 304 outward to release the fixation of the lower end of the torsion spring 305, so that the torque of the torsion spring 305 is released. Then, fold the brush assembly 2 by using the handle 7 so that the card block 9 and the card slot 8 magnetically engage, thereby completing the limiting folding of the brush assembly 2. The brush power unit 201 on one side and the pulley 5 can then be placed in contact with the ground.

[0035] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
