Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a wastewater tank and a floor scrubber. Background Technology

[0002] A floor scrubber is a cleaning device that integrates vacuuming, mopping, and scrubbing for cleaning floors. To meet various usage scenarios, current floor scrubbers can be used at any angle, from lying flat to standing upright. Therefore, the sealing requirements for the wastewater tank are becoming increasingly stringent. When the sealing requirements for the wastewater tank are high, an overly tight seal between the wastewater cover assembly and the tank shell makes it difficult to separate them, thus reducing the user experience. Utility Model Content

[0003] This application provides a wastewater tank and a floor scrubbing machine to solve the technical problem that when the sealing requirements of the wastewater tank in the floor scrubbing machine are high, the sealing installation between the wastewater cover assembly and the wastewater tank shell is too tight, making it difficult to separate the wastewater cover assembly and the wastewater tank shell, thereby reducing the user experience.

[0004] To solve the above-mentioned technical problems, this application proposes a sewage tank, comprising: a sewage tank shell with a sewage installation port; a sewage cover assembly sealed to the sewage installation port, with inner lining rotating shafts on both sides of the sewage cover assembly; and an inner lining handle assembly including two inner lining rotating parts and an inner lining handle connected to the two inner lining rotating parts, wherein the inner lining rotating parts are at least partially located on the top surface of the sewage tank shell, and the inner lining rotating parts form a first movement groove, with the inner lining rotating shafts located in the first movement groove; wherein, rotating the inner lining handle causes the inner lining rotating parts to press against the top surface of the sewage tank shell, and the inner lining rotating shafts move along the first movement groove until the inner lining rotating shafts move away from the top surface of the sewage tank shell.

[0005] The inner lining rotating component has at least a first position and a second position; when the inner lining rotating component is in the first position, the inner lining rotating shaft is located at the first end of the first motion groove, and the inner lining handle is located on the upper surface of the sewage cover assembly; when the inner lining rotating component is in the second position, the inner lining rotating shaft moves along the first motion groove.

[0006] The first motion groove is arranged in an arc shape.

[0007] The sewage tank shell has an inner lining step on its top surface, and the inner lining step is inclined to have an inner lining abutment surface; in the first position, the inner lining rotating part is at least partially located on the inner lining abutment surface.

[0008] The inner lining rotating component includes a second moving groove, which is connected to the first moving groove, and the inner lining rotating shaft moves between the first moving groove and the second moving groove.

[0009] The first and second motion slots are arranged in an arc shape.

[0010] The top surface of the sewage tank shell is provided with an inner lining support, which supports the inner lining handle.

[0011] The sewage cover assembly includes a sewage liner assembly and a sewage tank cover. The sewage liner assembly is sealed and connected to the sewage installation port. The sewage tank cover is connected to the sewage liner assembly, and liner pivots are provided on both sides of the sewage tank cover.

[0012] The sewage tank cover has symmetrical inner lining mounting grooves on both sides, and the inner lining rotating shaft is located on the side wall of the corresponding inner lining mounting groove. The inner lining rotating component rotates clockwise relative to the sewage tank shell.

[0013] To solve the above-mentioned technical problems, this application proposes a floor scrubbing machine, including the aforementioned wastewater tank.

[0014] This application's wastewater tank includes a wastewater tank shell, a wastewater cover assembly, and an inner liner handle assembly. The wastewater tank shell has a wastewater installation port. The wastewater cover assembly is sealed to the wastewater installation port. Inner liner rotating shafts are provided on both sides of the wastewater cover assembly. The inner liner handle assembly includes two inner liner rotating members and an inner liner handle member connected to the two inner liner rotating members. The inner liner rotating members are at least partially located on the top surface of the wastewater tank shell. The inner liner rotating members form a first movement groove. The inner liner rotating shafts are located in the first movement groove. When the inner liner handle member is rotated, the inner liner rotating members press against the top surface of the wastewater tank shell. The inner liner rotating shafts move along the first movement groove until the inner liner rotating shafts move away from the top surface of the wastewater tank shell.

[0015] By rotating the inner liner handle, the inner liner handle works together to rotate the two inner liner rotating parts. The inner liner rotating parts rotate and squeeze the top surface of the sewage tank shell. The inner liner rotating shaft moves along the first motion groove until the inner liner rotating shaft moves away from the top surface of the sewage tank shell. At this time, the sewage cover assembly has a certain stroke of movement, which makes the seal between the sewage cover assembly and the sewage tank shell separate. Then, by lifting the inner liner handle, the sewage cover assembly and the sewage tank shell can be easily and completely separated.

[0016] Through the combined action of the aforementioned sewage tank shell, sewage cover assembly, and inner lining handle assembly, the seal between the sewage cover assembly and the sewage tank shell can be separated, making it easy to remove the sewage cover assembly and thus improving the user experience.

Detailed Implementation

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0036] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0037] The wastewater tank and floor scrubbing machine provided by this utility model will be described in detail below with reference to the embodiments.

[0038] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 , Figure 1 This is an exploded schematic diagram of an embodiment of the sewage tank of this application; Figure 2 This is a first partial cross-sectional schematic diagram of an embodiment of the sewage tank of this application in a first position; Figure 3 yes Figure 2 The diagram shows the structure of C. Figure 4This is a partial cross-sectional schematic diagram of a wastewater tank in a second position according to an embodiment of this application; Figure 5 yes Figure 4 The diagram shows the structure of D. This application provides a sewage tank. The sewage tank 20 includes a sewage tank shell 21 and a sewage cover assembly (not shown in the figure). The sewage tank shell 21 is provided with a sewage installation port 2111. The sewage installation port 2111 provides an installation position for the sewage cover assembly. The sewage cover assembly is sealed to the sewage installation port 2111. The sewage cover assembly can be sealed to the sewage installation port 2111 via a sewage inner lining sealing ring 224, satisfying the sealing requirements of the sewage tank 20, so that the sewage tank 20 can be used at any angle, such as lying flat or standing upright. The sewage cover assembly is at least partially located inside the sewage tank shell 21 and at least partially located on the top of the sewage tank shell 21. Inner lining rotating shafts 251 are provided on both sides of the sewage cover assembly. The inner lining rotating shafts 251 are detachable or fixed to both sides of the sewage cover assembly. In this embodiment, the inner lining rotating shafts 251 are welded to or integrally formed with the sewage cover assembly.

[0039] The wastewater tank 20 also includes an inner lining handle assembly 26. The inner lining handle assembly 26 includes two inner lining rotating parts 261 and an inner lining handle 262. The inner lining handle 262 is connected between the two inner lining rotating parts 261. Specifically, one end of the inner lining handle 262 is connected to one inner lining rotating part 261. One end of the inner lining handle 262 is welded to or integrally formed with one inner lining rotating part 261. The other end of the inner lining handle 262 is connected to the other inner lining rotating part 261. The other end of the inner lining handle 262 is welded to or integrally formed with the other inner lining rotating part 261. By acting on the inner lining handle 262, the inner lining handle 262 collectively acts on the rotation of the two inner lining rotating parts 261, ensuring not only the consistency of movement of the two inner lining rotating parts 261 but also facilitating gripping or grasping, thereby further improving the user experience.

[0040] The inner lining rotating member 261 is at least partially located on the top surface of the sewage tank shell 21. Specifically, one inner lining rotating member 261 is at least partially located on one side of the top surface of the sewage tank shell 21; the other inner lining rotating member 261 is at least partially located on the other side of the top surface of the sewage tank shell 21. One side of the top surface of the sewage tank shell 21 can be the left top surface of the sewage tank shell 21; the other side of the top surface of the sewage tank shell 21 can be the right top surface of the sewage tank shell 21. The inner lining rotating member 261 has a first movement groove 26121. The inner lining rotating shaft 251 is located in the first movement groove 26121. That is, the inner lining rotating shaft 251 and the first movement groove 26121 rotate relative to each other.

[0041] By rotating the inner lining handle 262, the inner lining handle 262 acts together to rotate the two inner lining rotating parts 261. The inner lining rotating parts 261 rotate and squeeze the top surface of the sewage tank shell 21. The inner lining rotating shaft 251 moves along the first moving groove 26121 until the inner lining rotating shaft 251 moves away from the top surface of the sewage tank shell 21. At this time, the sewage cover assembly has a certain stroke of movement, which makes the seal between the sewage cover assembly and the sewage tank shell 21 separate. Then, by lifting the inner lining handle 262, the sewage cover assembly and the sewage tank shell 21 can be easily and completely separated.

[0042] Through the combined action of the sewage tank shell 21, the sewage cover assembly, and the inner lining handle assembly 26, the seal between the sewage cover assembly and the sewage tank shell 21 can be separated, making it easy to remove the sewage cover assembly and thus improving the user experience.

[0043] In some embodiments, the liner rotator 261 has at least a first position and a second position. For example... Figure 2 As shown, when the inner lining handle assembly 26 is in the first position, the inner lining rotating shaft 251 is located at the first end of the first moving groove 26121, and the inner lining handle 262 is located on the upper surface of the sewage cover assembly. The first position can be the initial state of the inner lining rotating component 261, at which time the sewage cover assembly is sealed to the sewage tank housing 21, the inner lining rotating component 261 is at least partially located on the top surface of the sewage tank housing 21, and the inner lining handle 262 is located on the upper surface of the sewage cover assembly.

[0044] When the inner liner handle assembly 26 is in the second position, the inner liner rotating shaft 251 moves away from the sewage tank housing 21 and along the first movement groove 26121, so that the sewage cover assembly is pushed out relative to the top of the sewage tank housing 21. The second position can be the state of the inner liner rotating member 261 after rotating from the first position. During the movement of the inner liner handle assembly 26 from the first position to the second position, the inner liner rotating member 261 rotates relative to the top surface of the sewage tank housing 21, pressing against the top surface of the sewage tank housing 21. The inner liner rotating shaft 251 moves along the first movement groove 26121, causing the sewage cover assembly to move vertically for a certain distance, thereby separating the seal between the sewage cover assembly and the sewage tank housing 21. Then, by lifting the inner liner handle 262, the sewage cover assembly and the sewage tank housing 21 can be easily and completely separated.

[0045] In some embodiments, the shape of the first motion groove 26121 is the same as the rotational path of the inner liner rotating member 261 relative to the top surface of the sewage tank housing 21, which can improve the smoothness of movement between the first motion groove 26121 and the inner liner rotating member 261, thereby reducing the risk of the inner liner rotating shaft 251 getting stuck in the first motion groove 26121 and ensuring the smooth ejection of the sewage cover assembly relative to the top of the sewage tank housing 21. As in this embodiment, the first motion groove 26121 is arc-shaped.

[0046] Please see Figure 6 , Figure 6 yes Figure 1 The structural diagram of A is shown below. (Combined with...) Figures 1 to 5 In some embodiments, the top surface of the sewage tank shell 21 is provided with an inner lining step portion 2113. The inner lining step portion 2113 is detachable or fixed to the top surface of the sewage tank shell 21. In this embodiment, for example, the inner lining step portion 2113 is welded or integrally formed onto the top surface of the sewage tank shell 21. There can be two inner lining step portions 2113. One inner lining step portion 2113 is located on one side of the top surface of the sewage tank shell 21, and is positioned below an inner lining rotating member 261. The other inner lining step portion 2113 is located on the other side of the top surface of the sewage tank shell 21, and is positioned below another inner lining rotating member 261.

[0047] The inner lining step portion 2113 is inclinedly provided with an inner lining abutment surface 21131. When the inner lining handle assembly 26 is in the first position, the inner lining rotating member 261 is at least partially located on the inner lining abutment surface 21131. When the inner lining rotating member 261 rotates relative to the top surface of the sewage tank housing 21, the inner lining rotating member 261 presses against the inner lining abutment surface 21131, which not only allows the sewage cover assembly to move in the vertical direction for a certain period of time, but also facilitates the separation of the seal between the sewage cover assembly and the sewage tank housing 21, thereby improving the user experience; it also improves the smoothness of the rotation of the inner lining rotating member 261 relative to the top surface of the sewage tank housing 21.

[0048] Specifically, the inner liner rotating component 261 engages with the inclined surface of the inner liner abutment surface 21131. The inner liner rotating component 261 is provided with an inclined inner liner surface 26123. The inclined inner liner surface 26123 engages with the inclined inner liner abutment surface 21131. When the inner liner rotating component 261 rotates relative to the top surface of the sewage tank housing 21, the inclined inner liner surface 26123 of the inner liner rotating component 261 presses against the inner liner abutment surface 21131. This not only allows the sewage cover assembly to move vertically for a certain distance, but also facilitates the separation of the seal between the sewage cover assembly and the sewage tank housing 21, thereby improving the user experience. Furthermore, it also improves the smoothness of the rotation of the inner liner rotating component 261, thereby reducing movement resistance and further enhancing the user experience.

[0049] Please see Figure 7 , Figure 8 as well as Figure 9 , Figure 7 This is a side view of the inner lining handle assembly in one embodiment of the wastewater tank of this application; Figure 8 This is a schematic diagram of a second partial cross-section of an embodiment of the wastewater tank of this application in a second position; Figure 9 yes Figure 8 The diagram shows the structure of F. (Combined with...) Figures 1 to 6 In some embodiments, the liner rotating member 261 includes a second movement groove 26122. The second movement groove 26122 and the first movement groove 26121 are connected. The liner rotating shaft 251 moves between the first movement groove 26121 and the second movement groove 26122. The liner rotating shaft 251 can move along the first movement groove 26121 to the second movement groove 26122; or, the liner rotating shaft 251 can move along the second movement groove 26122 to the first movement groove 26121.

[0050] After the sewage cover assembly and the sewage tank shell 21 are sealed and separated, the inner liner rotating part 261 is lifted and the inner liner rotating shaft 251 rotates to the second motion groove 26122, and then the sewage cover assembly and the sewage tank shell 21 can be completely separated.

[0051] After the wastewater cover assembly is sealed and installed on the wastewater tank housing 21, the inner liner rotating component 261 is turned. When the inner liner rotating component 261 falls, it will move along the second motion groove 26122 to the first motion groove 26121 under its own gravity and reset. Alternatively, the inner liner handle assembly 26 can be reset by slightly resetting it to the first motion groove 26121 under a slight horizontal force during assembly with the floor scrubber body.

[0052] With the cooperation of the first movement groove 26121 and the second movement groove 26122, the inner lining rotating shaft 251 can move between the first movement groove 26121 and the second movement groove 26122 of the inner lining rotating component 261. The range of motion is increased, which not only makes it easy to achieve the sealed separation between the sewage cover assembly and the sewage tank shell 21, but also effectively avoids the occurrence of movement interference. It can realize the automatic and effective reset of the inner lining rotating component 261, and avoid the phenomenon that the sewage cover assembly is stuck in the sewage tank shell 21 after the inner lining rotating component 261 is lifted.

[0053] Please see Figure 10 , Figure 10 This is a structural schematic diagram of the inner lining handle assembly in one embodiment of the sewage tank of this application. (Combined with...) Figures 1 to 9In some embodiments, the first motion groove 26121 and the second motion groove 26122 are arranged in an arc shape. The first motion groove 26121 may be, but is not limited to, arc-shaped; the second motion groove 26122 may be, but is not limited to, arc-shaped or circular, etc. By assembling the first motion groove 26121 and the second motion groove 26122 as described above, not only can the sealed separation between the sewage cover assembly and the sewage tank shell 21 be easily achieved, improving the user experience, but it also effectively avoids motion interference and enables the automatic and effective reset of the inner lining rotating component 261.

[0054] In some other embodiments, the inner lining handle assembly 26 includes two inner lining rotating members 261, but no inner lining handle member 262. There are at least two ways to release the seal between the sewage cover assembly and the sewage tank housing 21. The first method involves acting on both inner lining rotating members 261 simultaneously to push both ends of the sewage cover assembly out relative to the top of the sewage tank housing 21. The second method involves first acting on one inner lining rotating member 261 to push one end of the sewage cover assembly out relative to the top of the sewage tank housing 21; then acting on the other inner lining rotating member 261 to push the other end of the sewage cover assembly out relative to the other side of the top of the sewage tank housing 21.

[0055] The aforementioned inner lining handle 262 rotates; or the two inner lining rotating parts 261 rotate independently or together, which can be operated manually by the user or automatically by the inner lining drive assembly (not shown in the figure). In one embodiment, the inner lining handle assembly 26 further includes an inner lining drive assembly. One end of the inner lining drive assembly is connected to one inner lining rotating part 261; the other end of the inner lining drive assembly is connected to another inner lining rotating part 261. The inner lining drive assembly simultaneously drives the inner lining rotating parts 261 to move, causing the sewage cover assembly to push out relative to the sewage tank housing 21. In another embodiment, the inner lining drive assembly is connected to the inner lining handle 262. The inner lining drive assembly drives the inner lining handle 262 to move, causing the sewage cover assembly to push out relative to the sewage tank housing 21. The aforementioned inner lining drive assembly can be, but is not limited to, motor drive, gear drive, and worm gear drive. The aforementioned inner lining drive assembly improves the automaticity of pushing the sewage cover assembly out relative to the sewage tank housing 21.

[0056] In some embodiments, two inner liner rotating members 261 are symmetrically arranged at both ends of the inner liner handle member 262. Inner liner rotating shafts 251 are symmetrically arranged on both sides of the sewage cover assembly. The two inner liner rotating members 261 and the two inner liner rotating shafts 251 are all symmetrically arranged. When the inner liner handle member 262 is rotated, it drives the inner liner rotating members 261 to rotate, which facilitates the simultaneous ejection of both ends of the sewage cover assembly relative to the top sides of the sewage tank housing 21, further improving the uniformity of force distribution during the separation of the sewage cover assembly, thereby further enhancing the user experience.

[0057] In some embodiments, the wastewater cover assembly includes a wastewater liner assembly 22 and a wastewater tank cover 25. The wastewater liner assembly 22 is sealed to the wastewater installation port 2111. The wastewater tank cover 25 is connected to the wastewater liner assembly 22. The wastewater tank cover 25 and the wastewater liner assembly 22 are detachably or fixedly connected. The wastewater tank cover 25 can move with the wastewater liner assembly 22. When the wastewater liner assembly 22 is removed or installed relative to the wastewater tank housing 21, the wastewater tank cover 25 is also removed or installed along with the wastewater liner assembly 22. The aforementioned liner pivot 251 is provided on both sides of the wastewater tank cover 25. The liner pivot 251 is welded or integrally formed to the wastewater tank cover 25. Alternatively, the aforementioned liner pivot 251 is provided on both sides of the wastewater liner assembly 22. The liner pivot 251 is welded or integrally formed to the side of the wastewater liner assembly 22.

[0058] Please see Figure 11 and Figure 12 , Figure 11 This is a schematic diagram of the structure of the sewage tank cover in one embodiment of the sewage tank of this application; Figure 12 yes Figure 11 The diagram shows the structure of G. (Combined with...) Figures 1 to 10 In some embodiments, lining mounting grooves 252 are symmetrically provided on both sides of the sewage tank cover 25. The two sides of the sewage tank cover 25 can be located at the left and right ends of the sewage tank cover 25, respectively. The lining rotating shaft 251 is located on the side wall of the corresponding lining mounting groove 252. Because the lining rotating shaft 251 is located at the first movement groove 26121 or the second movement groove 26122 of the lining rotating member 261, the lining rotating member 261 is at least partially located within the lining mounting groove 252. The lining rotating member 261 can rotate clockwise relative to the sewage tank shell 21, so that the lining rotating member 261 changes from a first position to a second position.

[0059] The lining mounting groove 252 of the wastewater tank cover 25 not only provides an installation position for the lining shaft 251, but also accommodates at least part of the lining rotating parts 261, facilitating the subsequent installation of the wastewater tank 20 onto the floor scrubber body. Additionally, when the lining handle assembly 26 also includes a lining handle 262, the lining handle 262, located on the lining support 2114, also serves a certain storage function.

[0060] Please see Figure 13 , Figure 14 , Figure 15 as well as Figure 16 , Figure 13 yes Figure 1 The structural diagram of B shown below; Figure 14 yes Figure 4 The diagram shows the structure of E. Figure 15 This is a second partial cross-sectional schematic diagram of an embodiment of the sewage tank of this application in a first position; Figure 16 yes Figure 15 The diagram shows the structure of H. (Combined with...) Figures 1 to 12 In some embodiments, an inner lining support 2114 is provided on the top surface of the wastewater tank housing 21. The inner lining support 2114 is detachable or fixed to the top surface of the wastewater tank housing 21. In this embodiment, the inner lining support 2114 is welded or integrally formed onto the top surface of the wastewater tank housing 21. The inner lining support 2114 at least partially protrudes from the top surface of the wastewater tank housing 21. The inner lining support 2114 supports the inner lining handle 262, not only maintaining a small gap between the inner lining rotating member 261 and the top of the wastewater tank housing 21 for easy handling by the user, but also allowing the inner lining handle 262 to be stored above the inner lining support 2114, thus facilitating the overall installation of the wastewater tank 20 onto the floor scrubber body.

[0061] The aforementioned inner lining support 2114 can be located on the front side of the top surface of the sewage tank shell 21. The inner lining support 2114 can be, but is not limited to, square or isosceles trapezoidal shapes. When the inner lining support 2114 supports the inner lining handle 262, the sewage tank cover 25 is provided with an inner lining support groove 253. The inner lining support groove 253 is used to avoid the inner lining support 2114, so that the inner lining support 2114 can support the inner lining support groove 253, etc.

[0062] In some embodiments, the wastewater liner assembly 22 includes a wastewater liner 223 and a wastewater liner sealing ring 224. The wastewater liner sealing ring 224 is disposed on the upper outer periphery of the wastewater liner 223. The wastewater liner 223 is interference-sealed to the wastewater installation port 2111 by the wastewater liner sealing ring 224, so that the wastewater liner assembly 22 is sealed to the wastewater installation port 2111 of the wastewater tank housing 21. The wastewater tank cover 25 and the wastewater liner assembly 22 may be fastened together by screws, but not limited to, so that the wastewater tank cover 25 and the wastewater liner assembly 22 form a whole, and then interference-sealed onto the upper part of the wastewater tank housing 21, etc.

[0063] Please see Figures 1 to 16 This application provides a floor scrubbing machine. The floor scrubbing machine (not shown in the figure) is used for cleaning floors, etc. The floor scrubbing machine includes a wastewater tank 20. It should be noted that the wastewater tank 20 in this embodiment is the same as the wastewater tank 20 described in the above embodiments, and will not be repeated here. By using the aforementioned wastewater tank 20, the seal between the wastewater cover assembly and the wastewater tank housing 21 can be separated, facilitating easy removal of the wastewater cover assembly, thereby improving the user experience, etc.
