Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a water tank assembly and a cleaning head. Background Technology

[0002] With the advancement of technology, people's requirements for floor cleaning tools have gradually increased. The first to emerge was the vacuum cleaner, which relies on electricity and generates negative pressure to suck up trash and dust from the floor. Classified by cleaning methods and the flow path of small and large particles of debris, this type of technology is generally categorized as air-dust circulation technology. However, due to the limitations of its working principle, vacuum cleaners cannot clean some trash and stains that are firmly attached to the floor. Therefore, a new type of floor cleaner, the "water-dust circulation" scrubber, has emerged. This scrubber uses a motor to drive a cleaning drum to wipe the floor, and it is also equipped with a water supply system and a water tank to clean the cleaning drum, thus perfectly cleaning the floor.

[0003] In existing technologies, the water tank assembly is generally inserted horizontally into the cleaning head of the floor scrubber or clipped vertically onto the upright of the floor scrubber. This results in the floor scrubber still being very heavy, and the user still feels too cumbersome when pushing and pulling the floor scrubber to clean. There is an urgent need to find a technical solution that can make the floor scrubber have a lighter operating feel. Utility Model Content

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Example 1 This utility model embodiment provides a water tank assembly 120, which can be connected to the cleaning head housing body 110a, see reference. Figures 1-5 As shown, it includes a water tank body 120a, a water tank sealing sidewall 120b, and a water tank rotatable flip-top assembly 120c; The middle section of the water tank body 120a is provided with a receiving groove for accommodating the hinge head assembly 40. The cross-section of the middle section of the water tank body 120a is rectangular, and the cross-sections of the two side sections of the water tank body 120a are semi-circular. The water tank sealing sidewall 120b is welded to the water tank body 120a; The top of the water tank body 120a is provided with a water tank opening slot 120a1, and the water tank rotatable flip-top assembly 120c is disposed in the water tank opening slot 120a1.

[0025] The water tank assembly 120 provided in this embodiment of the utility model has a receiving groove for accommodating the hinge head assembly 40 in the middle section of the water tank body 120a. The cross-section of the middle section of the water tank body is rectangular, and the cross-sections of the two side sections of the water tank body are semi-circular, so that the hinge head assembly 40 can be inserted into the receiving groove. The shape of the water tank body 120a can also match the cleaning head housing body 110a while ensuring the water storage capacity, thus improving the structural compactness of the cleaning tool. By tightly connecting the water tank sealing side wall 120b to the water tank body 120a, the airtightness of the water tank body 120a is ensured. On this basis, a water tank opening slot 120a1 and a water tank rotatable flip-top assembly 120c are provided on the top of the water tank body 120a to ensure smooth water filling and effectively prevent water overflow.

[0026] The water tank assembly 120 provided in this embodiment is positioned flush with the height of the cleaning head housing 110a. It features a lightweight design with semi-circular sections on both sides and a recessed section in the middle, physically reducing the overall weight of the machine. Compared to existing floor scrubbers, it eliminates the redundant water tank support and avoids the bulkiness caused by placing the water tank in a vertical frame. The low-position installation of the water tank concentrates the weight on the lower chassis, resulting in excellent dynamic stability. Users will find the machine very stable and easy to control during cleaning, whether moving forward, backward, or turning around furniture. This reduces operator fatigue caused by machine shaking and instability, enhancing the cleaning experience.

[0027] The water tank assembly 120 provided in this embodiment of the invention significantly improves the user's handling due to the combined effect of weight reduction and a lower center of gravity. Pushing and pulling a machine with a low center of gravity and reasonable weight distribution is much easier and more agile than pushing and pulling a machine with the same total weight but that is top-heavy or unevenly distributed. The integrated design reduces the number of parts, simplifies the assembly process, and helps to reduce production costs and improve assembly efficiency.

[0028] In an optional implementation, refer to Figures 1-5As shown, the rotatable flip-top assembly 120c of the water tank is equipped with an air vent and a one-way vent valve (not shown in the figure); the rotatable flip-top assembly 120c of the water tank is equipped with a connecting air vent and a one-way vent valve; the one-way vent valve is used to restrict the flow of gas from outside the water tank body 120a to inside the water tank body 120a. When the water pump 40A draws water from the water tank, the liquid level in the water tank drops, the internal space increases, resulting in a pressure lower than the external atmospheric pressure. This negative pressure difference acts on the one-way vent valve, pushing the sealing plate of the one-way vent valve outward, allowing external air to enter the water tank through the air vent, quickly balancing the internal and external pressures. When the internal and external pressures of the water tank are balanced, the elastic seal inside the one-way vent valve closes under its own pre-tightening force or gravity, blocking the air vent and keeping the inside of the water tank in a sealed state. When the water tank is tilted, it can effectively avoid water leakage caused by changes in internal pressure, greatly improving the reliability of the product and the user experience.

[0029] In an optional implementation, refer to Figures 1-5 As shown, the water tank rotatable flip-top assembly 120c is hinged to the inner wall of the water tank opening slot 120a1, enabling the water tank rotatable flip-top assembly 120c to flip and close above the water tank opening slot 120a1, providing convenience for adding water.

[0030] In an optional implementation, refer to Figures 1-5 and Figure 8 As shown, the water tank body 120a is provided with a water tank body clearance notch 120a5 for cable routing, and the water tank sealing sidewall 120b is correspondingly provided with a water tank sealing sidewall clearance notch 120b5. The pipeline connecting the water pump can pass through the water tank body clearance notch 120a5 and the water tank sealing sidewall clearance notch 120b5 to connect with the cleaning head housing body 110a. The clearance notch design provides a centralized and concealed cable routing channel, reducing the complexity of the cable layout, improving the overall space utilization and compactness of the cleaning head, and ensuring visual aesthetics.

[0031] In an optional implementation, refer to Figures 1-8 As shown, a first connecting seat 120a3 and a second connecting seat 120a4 for connecting the cleaning head housing body 110a are provided in the receiving groove. The first connecting seat 120a3 and the second connecting seat 120a4 can be fixedly connected to the first fixing seat 110a3 and the second fixing seat 110a4 on the cleaning head housing body 110a respectively, thereby realizing the fixed connection between the water tank body 120a and the cleaning head housing body 110a in the horizontal direction and ensuring a stable connection.

[0032] Furthermore, refer to Figures 1-5 and Figure 8As shown, the water tank sealing sidewall is provided with connecting ears 120b1 and 120b2 at both ends. The water tank assembly 120 can be fixedly connected to the cleaning head housing body 110a through the two connecting ears, which further ensures the stability of the connection.

[0033] In an optional implementation, refer to Figures 1-5 As shown, a sealing connection groove 120a6 is provided at the bottom of the water tank body 120a; the sealing connection groove 120a6 is tightly connected to the sealing side wall 120b of the water tank. Specifically, the sealing connection groove 120a6 is connected to the sealing side wall 120b of the water tank by adhesive application or ultrasonic welding, thereby ensuring a tight connection and preventing water from overflowing.

[0034] In an optional implementation, refer to Figures 1-5 As shown, the lower middle part of the water tank body 120a is also provided with a pipeline channel for connecting the water outlet 120a2 and the water pump 40A installed in the hinge head assembly 40; the water outlet 120a2 is a water outlet connector protruding to the side of the pipeline channel, and the water inlet is located on the opening groove. Through the cooperation of the water outlet 120a2 and the pipeline channel, the clean water in the water tank assembly 120 can be smoothly pumped out and delivered to the outer wiping layer 10B of the cleaning roller.

[0035] Example 2 Based on the same inventive concept, this utility model embodiment also provides a cleaning head 10, see reference. Figure 4 , Figure 9 and Figure 10 As shown, it includes a cleaning head housing assembly 110 and a water tank assembly 120 as described in Embodiment 1.
