Description

Technical Field

[0001] This application relates to the field of wastewater tanks, and in particular to a handle structure for a wastewater tank of a floor scrubber. Background Technology

[0002] Floor scrubbers are popular among consumers due to their ease of operation and flexible handling. Since the wastewater tank is installed inside the machine body, a handle is usually installed on the tank to facilitate easy removal and cleaning of the wastewater inside.

[0003] However, existing technologies only install handles at the top of the wastewater tank, but the handles are usually higher than the wastewater tank or exposed outside the wastewater tank. This makes it inconvenient to operate the floor scrubber when using it, it is not conducive to the floor scrubber lying flat, and it is not aesthetically pleasing. Utility Model Content

[0004] To facilitate easy removal of the wastewater tank cover for user cleaning, this application provides a handle structure for the wastewater tank of a floor scrubber.

[0005] The handle structure of the wastewater tank of the floor scrubber provided in this application adopts the following technical solution:

[0006] include:

[0007] Bottom cover;

[0008] The upper cover is located on the lower cover, and an opening is provided on the upper cover;

[0009] The handle mechanism facilitates the removal of the wastewater tank and is used to unlock and remove the wastewater tank from the floor scrubber.

[0010] The handle mechanism includes a mounting plate disposed in the opening, a handle plate rotatably disposed on the mounting plate, and a locking member for limiting the handle plate; the handle plate is located in the opening, and by rotating the handle plate, the locking member is released from limiting the handle plate so that part of the handle plate is located outside the opening.

[0011] In one possible implementation, the end face of the handle plate is at the same level as the outer wall of the top cover.

[0012] In one possible implementation, the handle plate is provided with a first connecting part, and the first connecting part has an avoidance groove. When the handle plate is rotated, the end wall of the opening is inserted into the avoidance groove.

[0013] In one possible implementation, the first connecting part is provided with a second connecting part, the second connecting part is provided with a rotating rod, and the mounting plate is provided with a rotating groove that cooperates with the rotating rod.

[0014] In one possible implementation, the locking element includes:

[0015] The fixing plate is fixedly mounted on the mounting plate;

[0016] The movable block is located within the opening of the top cover;

[0017] A spring, one end of which is connected to a fixed plate and the other end of which is connected to a movable block;

[0018] The locking block is fixedly mounted on the movable block;

[0019] Support plates are symmetrically arranged on the movable blocks;

[0020] The top cover has a lock groove for the lock block to pass through, and the handle plate has a pressure plate, one end of which abuts against the support plate.

[0021] In one possible implementation, the locking element further includes:

[0022] The first limiting post is fixedly mounted on the fixing plate;

[0023] The second limiting post is fixedly installed on the movable block;

[0024] The two ends of the spring are respectively sleeved on the first limiting post and the second limiting post.

[0025] In one possible implementation, the handle mechanism is provided with a limiting plate, one end of which abuts against one end of the fixed plate.

[0026] In one possible implementation, the mounting plate is configured to have a receiving cavity formed by an inward recess.

[0027] In one possible implementation, the mounting plate has a slot, and the top cover has a locking block that is embedded in the slot.

[0028] In one possible implementation, the mounting plate is provided with a baffle, one end of which abuts against the inner wall of the opening.

[0029] In summary, this application includes the following beneficial technical effects: When the wastewater tank needs to be removed from the floor scrubber to clean the waste inside, rotating the handle mechanism causes one end of the pressure plate to rotate, squeezing the support plate downwards. The support plate then moves the movable block downwards, compressing the spring and disengaging the locking block from the locking groove. This unlocking process allows the user to easily lift the wastewater tank for cleaning. This enables effortless and convenient removal of the wastewater tank, while also preventing wastewater from splashing out, thereby improving cleaning efficiency and user experience.

[0030] When the top cover of the wastewater tank does not need to be removed, the handle is located inside the opening. This reduces the use of the handle mechanism, minimizes the risk of misoperation, and improves safety. On the other hand, it ensures the overall flatness of the wastewater tank's exterior, with no protruding structures for gripping the handle, thus maintaining the tank's aesthetic appeal. It also facilitates the flat laying of the wastewater tank for use, making it compatible with various floor scrubber models on the market and widely applicable. Attached Figure Description

[0039] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0040] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of this application and are not intended to limit the scope of protection of the embodiments of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0041] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0042] In the embodiments of this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0043] Reference Figure 1-7 The wastewater tank of a floor scrubber has a handle structure, including a wastewater tank body installed inside the machine body. The wastewater tank body includes a lower cover 1, an upper cover 2, and a handle mechanism. The lower cover 1 has a wastewater chamber, and the upper cover 2 is connected to the lower cover 1 by a snap-fit ​​connection. The handle mechanism is used to remove the upper cover 2 from the lower cover 1. Specifically, the handle mechanism includes a mounting plate 3, a handle plate 4, a locking component, and a connecting component. The upper cover 2 has an opening 5, and the mounting plate 3 is installed in the opening 5. The handle plate 4 is rotatably mounted on the mounting plate 3 via the connecting component. The locking component limits the position of the handle plate 4, which is located inside the opening 5. The end face of the handle plate 4 is on the same plane as the outer wall of the upper cover 2. Rotating the handle plate 4 releases the locking component from limiting the position of the handle plate 4, allowing part of the handle plate 4 to be outside the opening 5. The mounting plate 3 is configured with an inwardly recessed receiving cavity 6, within which the handle plate 4, locking components, and connecting components are all located. When the top cover 2 of the wastewater tank does not need to be removed, the handle plate 4 is located within the opening 5. This reduces the use of the handle mechanism, minimizing the risk of misoperation and improving safety. Furthermore, it ensures the overall flatness of the wastewater tank's exterior, eliminating protruding structures for gripping and maintaining its aesthetic appeal. It also facilitates the flat laying of the wastewater tank, making it compatible with various floor scrubber models on the market and possessing wide applicability.

[0044] The connecting parts are symmetrically arranged on the handle plate 4. The connecting parts include a first connecting part 7, a second connecting part 8, a rotating rod 9, a pressure plate 10, and a limiting plate 11. The first connecting part 7 is fixedly arranged on the handle plate 4, the second connecting part 8 is fixedly arranged on the first connecting part 7, the rotating rod 9 is fixedly arranged on the second connecting part 8, the mounting plate 3 has a rotating groove 12, the rotating rod 9 is rotatably arranged in the rotating groove 12, the pressure plate 10 is fixedly arranged on the first connecting part 7, and one end is connected to the handle plate 4. The limiting plate 11 is fixedly arranged on the handle plate 4. Among them, the first connecting part 7 has a relief groove 13. When the handle plate 4 rotates, the relief groove 13 on the first connecting part 7 will move to the side of the opening 5, so that the end wall of the opening 5 will be inserted into the relief groove 13 as the handle plate 4 rotates, thereby preventing the end wall of the opening 5 from obstructing the rotation of the handle plate 4.

[0045] The locking mechanism includes a fixed plate 14, a movable block 15, a first limiting post 16, a second limiting post 17, a spring 18, a locking block 19, and a support plate 20. The fixed plate 14 is fixedly mounted on the mounting plate 3, the movable block 15 is movably mounted in the opening 5 of the upper cover 2, the first limiting post 16 is fixedly mounted on the fixed plate 14, the second limiting post 17 is fixedly mounted on the movable block 15, one end of the spring 18 is connected to the fixed plate 14, and the other end is connected to the movable block 15. The locking block 19 is fixedly mounted on the movable block 15 and respectively fitted onto the first limiting post 16 and the second limiting post 17. The upper cover 2 has a locking groove 21 for the locking block 19 to pass through. Under the action of the locking block 19, the handle plate 4 is prevented from rotating outside the opening 5 without human operation, thus affecting the use of the sewage tank. The support plate 20 is fixedly and symmetrically mounted on the movable block 15. One end of the pressure plate 10 abuts against the support plate 20. The lower surface of the limiting plate 11 abuts against the upper surface of the fixed plate 14.

[0046] The mounting plate 3 has a slot 22, and the upper cover 2 has a block 23 that is embedded in the slot 22. The mounting plate 3 has a baffle 24, one end of which abuts against the inner wall of the opening 5.

[0047] The specific operation process is as follows:

[0048] When it is necessary to remove the upper cover 2 to clean the inside of the lower cover 1, or to clean solid waste inside the upper cover 2, rotate the handle plate 4. One end of the pressure plate 10 rotates with the handle mechanism, squeezing the support plate 20 downwards. The support plate 20 drives the movable block 15 downwards, compressing the spring 18, causing the locking block 19 to disengage from the locking groove 21, thus allowing the upper cover 2 to be easily removed from the lower cover 1. This achieves easy and convenient removal of the sewage tank upper cover 2, while also preventing sewage from splashing out of the sewage tank, thereby improving user cleaning efficiency and enhancing the user experience.
