Technical Field

[0001] This utility model relates to the field of semiconductor manufacturing, and in particular to a sealing strip for a floor scrubber water tank and a floor scrubber. Background Technology

[0002] Environmental hygiene is an important factor affecting the quality of life. Therefore, as people’s requirements for quality of life continue to increase, their requirements for environmental hygiene are also getting higher and higher. However, modern people’s work pressure is increasing day by day, and they urgently need to be freed from heavy cleaning work. As a result, many floor cleaning devices have emerged to improve environmental hygiene, such as vacuum cleaners, automatic mops, sweepers and floor scrubbers.

[0003] Sealing strips on floor scrubbers are crucial sealing components that ensure the normal operation of the equipment. Their core function is to prevent liquid leakage and block the intrusion of impurities. When the floor scrubber is working, a negative pressure is created inside the wastewater tank due to vacuum suction. The sealing strips can tightly fit the gaps between the tank body and the lid to prevent wastewater from leaking into the equipment or onto the floor due to the pressure difference, thus avoiding secondary pollution.

[0004] However, the sealing strips in the water tanks of current floor scrubbers are still inadequate. Utility Model Content

The sealing strip is suitable for interference fit with at least one of the tank body and the tank cover of the floor scrubber water tank.

[0036] As can be seen from the background technology, the sealing strips of current floor scrubber water tanks have shortcomings. The reasons for these shortcomings are analyzed below:

[0037] Please refer to Figure 1A sealing strip 100 for a floor scrubber water tank is provided. The sealing strip 100 is applicable between the end face of the tank body and the end face of the tank cover of the floor scrubber water tank. The sealing strip 100 includes: a first side 100a and a second side 100b opposite to each other. The first side 100a is adapted to contact the end face of the tank cover, and the second side 100b is adapted to contact the end face of the tank body.

[0038] Please refer to Figure 2 A floor scrubber includes: a housing; a housing cover that cooperates with the housing; and a sealing strip 100 for the floor scrubber water tank as described above.

[0039] The lid includes a first end face, the body includes a second end face, and the sealing strip 100 is located between the first end face and the second end face, wherein the first end face is the end face of the lid facing the body, and the second end face is the end face of the body facing the lid.

[0040] Specifically, the first side 100a of the sealing strip 100 is adapted to contact the first end face; the second side 100b of the sealing strip 100 is adapted to contact the second end face.

[0041] The container has a cavity for storing wastewater.

[0042] The floor scrubber also includes a water suction motor, which is adapted to generate negative pressure in the cavity inside the casing.

[0043] The floor scrubber also includes a brush plate adapted to clean stains on the floor.

[0044] Please refer to Figure 3 The floor scrubber also includes: a clip 102.

[0045] The buckle 102 is used to press the lid onto the body of the machine to prevent sewage leakage from the water tank of the floor scrubber.

[0046] Specifically, by pressing the buckle 102, the sealing strip 100 located between the first end face and the second end face is deformed. The sealing strip 100 is sealed between the first end face and the second end face by sealing the upper and lower end faces, thereby achieving the sealing of the floor scrubber water tank.

[0047] When the floor scrubber is working normally, the water suction motor works, which creates a negative pressure inside the chamber. Under the action of the negative pressure and the squeezing of the buckle 102, the sealing strip 100 undergoes elastic deformation. The elastically deformed sealing strip 100 is sealed between the first end face and the second end face by sealing the upper and lower end faces to prevent sewage leakage from the chamber.

[0048] When the floor scrubber is in transport mode, the water suction motor is not working and cannot generate negative pressure inside the box. The sealing strip 100 needs to undergo elastic deformation under the action of the buckle 102. The elastically deformed sealing strip 100 is sealed between the first end face and the second end face.

[0049] When the floor scrubber is idle, its placement is adjusted to suspend the brush disc in the air to reduce wear and tear. At this time, the scrubber's center of gravity shifts, making it easier for wastewater stored in the chamber to leak. Furthermore, the scrubber's suction motor is not operating, preventing it from creating negative pressure within the chamber. The sealing strip 100 only deforms under the action of the clip 102 to seal between the first and second end faces.

[0050] The sealing method of the upper and lower end faces of the sealing strip 100 will result in poor sealing effect of the floor scrubber water tank, which will easily cause the sewage stored in the floor scrubber to leak.

[0051] To solve the aforementioned technical problem, this utility model provides a sealing strip for a floor scrubber water tank. The sealing strip is suitable for an interference fit with at least one of the tank body and the tank cover of the floor scrubber water tank. The sealing strip includes a sealing part located between the side wall of the tank cover and the side wall of the tank body. The interference fit is achieved by the deformation of the sealing part.

[0052] In the sealing strip of this utility model, the sealing part is located between the side wall of the box cover and the side wall of the box body. The sealing strip undergoes elastic deformation under the compression of the side wall of the box body and the side wall of the box cover. The elastically deformed sealing strip fills the gap between the side wall of the box body and the side wall of the box cover. The sealing strip prevents sewage from leaking out of the box body by side sealing, thereby improving the sealing effect of the floor scrubber water tank.

[0053] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0054] Please refer to Figure 4 The sealing strip 200 of the floor scrubber water tank includes a sealing part 201, which is located between the side wall of the tank cover and the side wall of the tank body.

[0055] There is a gap between the side wall of the lid and the side wall of the body. When the sealing strip 200 is squeezed by the side wall of the lid and the side wall of the body, the sealing part 201 will undergo elastic deformation and fill the gap between the side wall of the lid and the side wall of the body. The sealing strip 200 prevents the liquid in the floor scrubber water tank from leaking out by side sealing. The sealing between the lid and the body can be achieved without the need for additional locking tools such as buckles, thus improving the sealing effect of the floor scrubber water tank.

[0056] Specifically, the sealing strip 200 achieves an interference fit through the deformation of the sealing part 201.

[0057] The sealing part 201 is designed to be slightly larger than the gap between the lid 400 and the body 300 so that the sealing part 201 can achieve an interference fit with the side wall of the lid 400 and the side wall of the body 300. Specifically, the size of the sealing part 201 is slightly larger than the gap between the lid 400 and the body 300 along the direction from the side wall of the lid to the side wall of the body.

[0058] After the sealing part 201 undergoes elastic deformation, it generates elastic stress. This elastic stress continuously acts between the side wall of the lid and the side wall of the box body, forming a stable contact pressure. This pressure ensures that the sealing strip 200 always fits tightly against the side wall of the lid and the side wall of the box body, maintaining the sealing effect. For example, the vibration of the floor scrubber during operation may cause the lid and the box body to loosen slightly, but the interference fit sealing strip 200 will be tightly sealed between the side wall of the lid and the side wall of the box body due to elastic stress, preventing gaps from appearing between the side walls of the lid and the side wall of the box body.

[0059] The material of the sealing part 201 has low stiffness. Stiffness is the ability of an object to resist elastic deformation (such as tension, compression, bending, torsion, etc.) when subjected to force. Under the same external force, the object with greater stiffness will deform less; the object with less stiffness will deform more.

[0060] The material of the sealing part 201 has low rigidity, so the sealing part 201 is more likely to undergo elastic deformation. The sealing part 201 is more likely to fill the gap between the side wall of the tank cover and the side wall of the tank body, so as to ensure the sealing performance of the floor scrubber water tank.

[0061] Specifically, in some embodiments of this utility model, the sealing part 201 is made of foamed rubber. Foamed rubber is an elastic material with a porous structure, formed by introducing a large number of air bubbles (closed-cell or open-cell) into a rubber matrix, combining the elasticity and wear resistance of rubber with the lightweight and heat insulation properties of foam materials. The foamed rubber has a low elastic modulus.

[0062] Please refer to Figure 5 The sealing part 201 includes a first sub-part 201a and at least one second sub-part 201b.

[0063] The first sub-part 201a forms a hollow cavity.

[0064] The first sub-part 201a forms a hollow cavity, so that when the sealing part 201 undergoes elastic deformation, the hollow cavity can accommodate the elastically deformed first sub-part 201a, providing sufficient space for elastic deformation; and, since the first sub-part 201a forms a hollow cavity, when the sealing strip 200 is squeezed by the side wall of the lid and the side wall of the box body, the hollow cavity compresses the internal air of the first sub-part 201a and the first sub-part 201a, so that the first sub-part 201a can produce a large deformation under a small pressure, making it easier for the sealing part 201 to fill the gap between the side wall of the lid 400 and the side wall of the box body 300.

[0065] Please continue to refer to this. Figure 5 The second sub-part 201b protrudes from the outer surface of the first sub-part 201a, facing away from the hollow cavity. Because the second sub-part 201b protrudes from the surface of the first sub-part 201a, when the sealing strip 200 is pressed by the side wall of the lid 400 and the side wall of the body 300, the second sub-part 201b can fit more tightly against the side wall of the body 300, increasing the actual contact area between the sealing strip 200 and the side wall of the body. Furthermore, the second sub-part 201b can act as a kind of "locking tenon," making it less likely for the sealing part 201 to detach from the side wall of the lid and the side wall of the body.

[0066] Specifically, in some embodiments of this utility model, the cross-sectional shape of the first sub-part 201a is a fan-shaped ring.

[0067] The first sub-part 201a forms a circumferential ring to create a sealing ring. The cross-section of the first sub-part 201a is the section of the sealing ring perpendicular to the circumferential direction.

[0068] The cross-section of the first sub-part 201a is set as a fan-shaped ring. When subjected to radial pressure, the fan-shaped ring can deform evenly in all directions, filling the gap between the side wall of the cover and the side wall of the box body, thereby achieving a good and uniform sealing effect. In addition, the shape of the fan-shaped ring does not have obvious sharp edges, which can form a continuous sealing boundary and reduce the possibility of sewage leakage inside the box. Furthermore, when the fan-shaped first sub-part 201a is subjected to external pressure, the elastic stress distribution is relatively uniform, and it is not easy for excessive local stress to occur, thereby extending the service life of the sealing strip 200.

[0069] Please continue to refer to this. Figure 4 The sealing strip 200 of the floor scrubber water tank further includes an installation part 202, which is connected to the sealing part 201 to achieve the fixed installation of the sealing strip 200.

[0070] The mounting part 202 is adapted to be snapped onto the floor scrubber so that the sealing strip 200 is fixed onto the floor scrubber. The mounting part 202 and the sealing part 201 are integrally formed.

[0071] Please refer to the reference. Figure 4 and Figure 6 The mounting part 202 includes a first wall 2021, which is connected to the sealing part 201.

[0072] The first wall 2021 is adapted to form an installation groove 206. The first wall 2021 is connected to the sealing part 201, so that when the installation groove 206 is snapped onto the cover of the floor scrubber, the sealing part 201 is fixed between the side wall of the cover and the side wall of the body.

[0073] Please refer to Figures 4 to 6 The first wall 2021 and the first sub-part 201a of the sealing part 201 form a hollow cavity. When the sealing strip 200 deforms under the action of external force, the hollow cavity formed by the first wall 2021 and the first sub-part 201a of the sealing part 201 can accommodate the elastically deformed first sub-part 201a, providing a space for the elastically deformed first sub-part 201a.

[0074] The mounting part 202 further includes: a second wall 2022 and a connecting bottom 2023, wherein the second wall 2022 is disposed opposite to the first wall 2021, and the connecting bottom 2023 connects the first wall 2021 and the second wall 2022; the second wall 2022 and the connecting bottom 2023 cooperate with the first wall 2021 to form a mounting groove 206.

[0075] The first wall 2021 and the second wall 2022 are arranged opposite to each other, and the distance between the first wall 2021 and the second wall 2022 defines the size of the opening of the formed mounting groove 206.

[0076] The connecting bottom 2023 connects the first wall 2021 and the second wall 2022, and the position of the connecting bottom defines the depth of the mounting groove 206.

[0077] The mounting groove 206 engages with the mounting ribs on the cover of the floor scrubber's water tank, thus securing the sealing strip 200 to the floor scrubber's water tank.

[0078] Please continue to refer to this. Figures 4 to 6 The top dimension of the mounting groove 206 is smaller than the bottom dimension of the mounting groove 206.

[0079] Please refer to the reference. Figure 4 With Figure 6 Along the opening direction Y of the mounting groove 206, both the first wall 2021 and the second wall 2022 have a first end and a second end. The first end 2021a of the first wall 2021 is connected to the connecting bottom 2023, and the first end 2022a of the second wall 2022 is connected to the connecting bottom 2023. The size of the top end of the mounting groove 206 is smaller than the size of the bottom end of the mounting groove 206, that is, the distance d2 between the second end 2021b of the first wall 2021 and the second end 2022b of the second wall 2022 is smaller than the distance d1 between the first end 2021a of the first wall 2021 and the first end 2022a of the second wall 2022, where d2 < d1.

[0080] The top dimension d2 of the mounting groove 206 is smaller than the bottom dimension d1 of the mounting groove 206. When the mounting rib is engaged in the mounting groove 206, the top of the mounting groove 206 exerts a greater squeezing force on the mounting rib, making it less likely for the mounting rib to fall out of the mounting groove 206, thereby making the sealing strip 200 more firmly fixed to the box cover.

[0081] Specifically, please refer to some embodiments of this utility model. Figure 4 Along the opening direction Y of the mounting groove 206, the size of the mounting groove 206 gradually decreases.

[0082] Please continue to refer to this. Figure 4 The mounting portion 202 includes a shaping portion 203 and a buffer portion 204 that wraps around the shaping portion 203.

[0083] The shaping part 203 is adapted to define the shape of the cross-section of the mounting groove 206, and the buffer part 204 is adapted to wrap the shaping part 203 so that the mounting part 202 can more easily undergo elastic deformation. If the mounting parts 202 are all made of high-rigidity material, it will be difficult for the mounting parts 202 to fit snugly against the side wall of the cover; if the mounting parts 202 are all made of low-rigidity material, the mounting parts 202 will not be able to maintain the preset shape due to lack of support, resulting in a deviation in the sealing position.

[0084] The material of the shaping part 203 has a higher stiffness than the material of the buffer part 204. Stiffness is the ability of an object to resist elastic deformation (such as tension, compression, bending, torsion, etc.) when subjected to force. Under the same external force, the object with greater stiffness will deform less; the object with less stiffness will deform more. The high stiffness of the material of the shaping part 203 provides a fixed contour shape for the sealing strip 200, preventing the sealing strip 200 from undergoing unexpected deformation due to force during assembly, compression, or long-term use, such as twisting, collapse, or excessive bending.

[0085] Specifically, in some embodiments of this utility model, the material of the shaping part 203 is steel wire braided tape; the material of the buffer part 204 is soft rubber.

[0086] Specifically, in some embodiments of this utility model, the rigidity of the material of the mounting part 202 is greater than the rigidity of the material of the sealing part 201.

[0087] The rigidity of the material of the mounting part 202 is greater than that of the material of the sealing part 201. That is, the rigidity of the materials of the shaping part 203 and the buffer part 204 that wraps the shaping part 203 is greater than that of the material of the sealing part 201.

[0088] The mounting part 202 further includes at least one limiting structure 205, which protrudes from the side wall surface of the mounting groove 206.

[0089] The limiting structure 205 protrudes from the side wall surface of the mounting groove 206. When the mounting groove 206 is engaged with the mounting ribs of the floor scrubber water tank cover, the mounting ribs are not easily dislodged from the mounting groove 206 due to the limiting structure 205 on the side wall surface of the mounting groove 206, and the limiting structure 205 improves the sealing performance of the sealing strip 200.

[0090] Specifically, the limiting structure 205 and the buffer portion 204 are integrally formed, and the limiting structure 205 and the buffer portion 204 are made of the same material. The limiting structure 205 is made of soft rubber.

[0091] Please refer to Figure 7The sealing strip 200 forms a sealing ring.

[0092] The sealing strip 200 forms a sealing ring, meaning it bends circumferentially to form a closed annular structure. This circumferentially closed annular structure creates a continuous, sealed barrier around the object being sealed (the side wall of the tank in this example), ensuring that the medium (the wastewater inside the tank in this example) cannot breach the sealing boundary from any direction. The sealing ring achieves a seamless seal around the entire circumference, preventing media leakage.

[0093] Accordingly, this utility model embodiment also provides a floor scrubbing machine, please refer to... Figures 7 to 10 The floor scrubber includes: a housing 300; a housing cover 400 that mates with the housing 300; and a sealing strip 200 for the water tank of the floor scrubber as described in this embodiment of the present invention, wherein the sealing strip 200 is interference-fitted with at least one of the housing 300 and the housing cover 400.

[0094] Please refer to Figure 7 The floor scrubber includes: a housing 300.

[0095] Specifically, the box 300 is a sewage tank.

[0096] Please continue to refer to this. Figure 7 The floor scrubber includes a cover 400, which cooperates with the body 300.

[0097] The lid 400 is matched with the body 300, that is, the shape and size of the lid 400 are adapted to the body 300.

[0098] Please continue to refer to this. Figure 7 The floor scrubber includes a sealing strip 200 for the floor scrubber water tank.

[0099] For details, please refer to the reference. Figure 4 and Figure 7 The sealing strip 200 includes a sealing part 201, which is located between the side wall of the cover 400 and the side wall of the body 300.

[0100] There is a gap between the side wall of the cover 400 and the side wall of the body 300. When the sealing strip 200 is squeezed by the side wall of the cover 400 and the side wall of the body 300, the sealing part 201 will undergo elastic deformation. The sealing part 201 fills the gap between the side wall of the cover 400 and the side wall of the body 300, so as to seal the cover 400 and the body 300 and enhance the sealing performance of the floor scrubber water tank.

[0101] Specifically, the sealing strip 200 achieves an interference fit through the deformation of the sealing part 201.

[0102] Please continue to refer to this. Figure 4 The sealing strip 200 of the floor scrubber water tank further includes an installation part 202, which is connected to the sealing part 201 to achieve the fixed installation of the sealing strip 200.

[0103] The mounting part 202 is adapted to be snapped onto the floor scrubber so that the sealing strip 200 is fixed onto the floor scrubber. The mounting part 202 and the sealing part 201 are integrally formed.

[0104] Please refer to the reference. Figure 4 and Figure 6 The mounting part 202 includes a first wall 2021, which is connected to the sealing part 201.

[0105] The first wall 2021 is adapted to form an installation groove 206. The first wall 2021 is connected to the sealing part 201, so that when the installation groove 206 is snapped onto the cover of the floor scrubber, the sealing part 201 is fixed between the side wall of the cover and the side wall of the body.

[0106] Please refer to Figures 4 to 6 The first wall 2021 and the first sub-part 201a of the sealing part 201 form a hollow cavity. When the sealing strip 200 deforms under the action of external force, the hollow cavity formed by the first wall 2021 and the first sub-part 201a of the sealing part 201 can accommodate the elastically deformed first sub-part 201a, providing a space for the elastically deformed first sub-part 201a.

[0107] The mounting part 202 further includes: a second wall 2022 and a connecting bottom 2023, wherein the second wall 2022 is disposed opposite to the first wall 2021, and the connecting bottom 2023 connects the first wall 2021 and the second wall 2022; the second wall 2022 and the connecting bottom 2023 cooperate with the first wall 2021 to form a mounting groove 206.

[0108] The first wall 2021 and the second wall 2022 are arranged opposite to each other, and the distance between the first wall 2021 and the second wall 2022 defines the size of the opening of the formed mounting groove 206.

[0109] The connecting bottom 2023 connects the first wall 2021 and the second wall 2022, and the position of the connecting bottom defines the depth of the mounting groove 206.

[0110] The mounting groove 206 engages with the mounting ribs on the cover of the floor scrubber's water tank, thus securing the sealing strip 200 to the floor scrubber's water tank.

[0111] Please refer to Figure 8 The housing 300 has a cavity for storing sewage, the cavity including a mating surface 3001.

[0112] The mating surface 3001 provides an installation base for the sealing strip 200, allowing the sealing strip 200 to adhere to the mating surface 3001, ensuring that the sealing strip 200 is in a stable position during assembly and will not shift or become misaligned due to the pressure when the cover 400 is closed.

[0113] Specifically, the sealing part 201 is located between the mating surface 3001 and the box cover 400.

[0114] When the lid 400 is closed, pressure is applied to the sealing part 201 located between the mating surface 3001 and the lid 400, forcing the sealing part 201 to undergo elastic deformation. This causes the sealing part 201 to fill the space between the mating surface 3001 and the lid 400, ensuring that the sealing part 201 is tightly fitted to both the mating surface 3001 and the lid 400, thus guaranteeing the sealing performance of the sealing part 201.

[0115] Please refer to Figure 9 The box cover 400 includes a mounting rib 4001, and the sealing part 201 is located between the side of the mounting rib 4001 and the mating surface 3001.

[0116] There is a gap between the mounting rib 4001 and the side wall of the housing 300. When the sealing part 201 is squeezed by the mounting rib 4001 and the side wall of the housing 300, the sealing part 201 will undergo elastic deformation and fill the gap between the mounting rib 4001 and the side wall of the housing 300, so as to seal the housing cover 400 and the housing 300 and enhance the sealing performance of the floor scrubber water tank. In addition, the mounting rib 4001 and the mounting groove 206 form a "concave-convex fit". During assembly, the mounting rib 4001 can be naturally embedded in the mounting groove 206 to fix the position of the sealing strip 200.

[0117] The floor scrubber also includes a water suction motor, which is adapted to generate negative pressure in the cavity inside the housing 300.

[0118] When the floor scrubber is working normally, the water suction motor operates, which creates a negative pressure inside the housing 300. Under the action of the negative pressure and the squeezing action of the side wall of the housing 300 and the side wall of the lid 400, the sealing strip 200 undergoes elastic deformation. The elastically deformed sealing strip 200 seals between the side wall of the housing 300 and the side wall of the lid 400, preventing sewage from leaking out of the housing 300.

[0119] When the floor scrubber is in transport mode, the water suction motor is not working, but the side wall of the housing 300 and the side wall of the lid 400 will squeeze the sealing strip 200, causing the sealing strip 200 to undergo elastic deformation. The elastically deformed sealing strip 200 seals between the side wall of the housing 300 and the side wall of the lid 400, preventing sewage from leaking out of the housing 300.

[0120] When the floor scrubber is idle, its placement is adjusted to suspend the brush disc in the air to reduce wear. At this time, the scrubber's center of gravity is raised, and the suction motor is not operating. However, the side walls of the housing 300 and the lid 400 compress the sealing strip 200, causing it to elastically deform. This elastically deformed sealing strip 200 seals between the side walls of the housing 300 and the lid 400, preventing wastewater leakage from the housing 300.

[0121] The sealing strip 200 fills the gap between the side wall of the tank cover and the side wall of the tank body. The sealing strip 200 prevents the liquid in the water tank of the floor scrubber from leaking out by sealing the side. It can achieve the seal between the tank cover and the tank body without the need for additional locking tools such as buckles, thus improving the sealing effect of the water tank of the floor scrubber.

[0122] Please refer to Figure 10 The floor scrubber also includes a clean water tank 500, which is adapted to provide cleaning fluid.

[0123] The floor scrubber works on the following principle: based on physical friction and water absorption mechanisms, the cleaning components agitate and remove dirt from the floor, while the water absorption components suck wastewater and dirt into the wastewater tank, achieving efficient floor cleaning. Cleaning solution from the clean water tank is sprayed onto the floor; upon contact with the dirt, the rotating friction of the brush plates peels the dirt off the floor.

[0124] Please refer to Figure 10 The floor scrubber also includes an operating handle 600, which is adapted to control the working state of the brush disc.

[0125] The floor scrubber also includes a battery pack located above the clean water tank.

[0126] The floor scrubber also includes a brush plate 700, which is adapted to clean the floor.

[0127] The bristles on the brush plate come into contact with and agitate the ground, effectively scrubbing the floor. The rotational friction of the brush plate can remove dirt and dust from the ground.

[0128] In summary, the sealing part 201 is located between the side wall of the cover 400 and the side wall of the body 300. The sealing strip 200 undergoes elastic deformation under the compression of the side wall of the body 300 and the side wall of the cover 400. The elastically deformed sealing strip 200 fills the gap between the side wall of the body 300 and the side wall of the cover 400. The sealing strip 200 prevents liquid leakage from the floor scrubber's water tank by providing a side seal, achieving a seal between the cover 400 and the body 300 without the need for additional locking tools such as clips, thus improving the sealing effect of the floor scrubber's water tank. When the floor scrubber is idle or in transport, even though the suction motor is not working, the sealing strip 200 can still effectively prevent sewage leakage from the floor scrubber's water tank by providing a side seal, ensuring the sealing performance of the floor scrubber in non-use scenarios and improving the user experience.
