Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning equipment, and in particular relates to a sewage tank and water-absorbing cleaning equipment using the sewage tank. Background Art

[0002] At present, water-absorbing cleaning equipment on the market, such as floor scrubbers, are equipped with a sewage tank and a clean water tank. The sewage tank is used to hold the sewage sucked up after washing and mopping the floor. Since there is a sewage suction pipe in the sewage tank, the sewage in the sewage suction pipe will hit the top of the sewage tank to the maximum extent during use, making the sewage and debris infinitely close to the position of the air suction port, thereby increasing the probability of sewage and debris entering the air suction port and contaminating the HEPA filter.

[0003] There is an existing sewage tank of a floor scrubber, and the upper end of its sewage suction pipe is provided with an anti-backflow structure to prevent the sewage in the tank from flowing back into the sewage suction pipe when the sewage tank is tilted. Although this anti-backflow structure can limit the height of the sewage impact in the sewage suction pipe to a certain extent, thereby reducing the probability of sewage and debris entering the air suction port and contaminating the HEPA filter, directly designing an anti-backflow structure at the upper end of the sewage suction pipe will affect the difficulty of demolding the sewage tank during die-casting. Therefore, in some embodiments, the inventor will detachably set this anti-backflow structure at the upper end of the sewage suction pipe, such as Chinese patent CN218356091U-A sewage tank and cleaning equipment. Although this structure solves the problem of die-casting production of the sewage tank, it adds an anti-backflow component, thereby increasing the assembly process; in other embodiments, the inventor will design the sewage suction pipe and the sewage tank as a split structure, so that the above-mentioned anti-backflow structure can be directly designed on the sewage suction pipe, but this also increases the assembly process of the sewage suction pipe and the sewage tank. Therefore, it is necessary to design an improved sewage tank structure to reduce the probability of sewage and debris entering the air intake and contaminating the HEPA filter while simplifying the assembly process. Utility Model Content

[0004] One of the purposes of the utility model is to provide a sewage tank with a simple structure, which can effectively reduce the probability of sewage and debris entering the air intake port and contaminating the HEPA filter without increasing the assembly process of the existing sewage tank.

[0005] The technical solution of the utility model is achieved in this way:

[0006] A sewage tank comprises a tank body and a tank cover, wherein the tank cover is arranged at the upper end of the tank body, and a partition is arranged at the lower end of the tank cover, and the partition extends into the upper area in the tank body to divide the upper area into a front area and a rear area, and a sewage suction pipe is arranged in the tank body, and the sewage suction pipe extends from the lower end of the tank body into the rear area at the upper end of the tank body, and the partition is provided with a blocking portion on the side facing the rear area, and the blocking portion is set at a distance from the lower end of the tank cover and protrudes at least to the upper area of ​​the sewage suction pipe.

[0007] Furthermore, the box body and the sewage suction pipe are designed in an integrated manner.

[0008] Furthermore, the enclosure portion and the partition portion are designed as an integrated unit.

[0009] Furthermore, an air suction port is provided at the lower end of the box cover, and the air suction port is located at one side of the front area.

[0010] Furthermore, the enclosure portion is configured to be U-shaped, so that the enclosure portion protrudes to the upper area and left and right side areas of the sewage suction pipe.

[0011] Furthermore, the height of the enclosure portion at least protrudes beyond the radial 2 / 3 of the sewage suction pipe away from the partition portion.

[0012] Furthermore, an air intake channel is provided on the box cover, the air intake channel is connected to the air intake port, and a HEPA filter is provided in the air intake channel.

[0013] Another object of the utility model is to provide a water-absorbing cleaning device, comprising a sewage tank, wherein the sewage tank is used to hold sewage sucked up after washing and mopping the surface to be cleaned, and the sewage tank adopts any of the sewage tanks described above.

[0014] The sewage tank of the utility model has a blocking part on the partition part. When the tank cover is installed on the tank body, the blocking part can naturally surround the sewage suction pipe, thereby blocking the sewage suction pipe to limit the height of the sewage impact in the sewage suction pipe, thereby preventing sewage and debris from approaching the air suction port. The utility model has a simple structure and can effectively reduce the probability of sewage and debris entering the air suction port and contaminating the HEPA filter, while not increasing the assembly process of the existing sewage tank.

[0015] The water-absorbing cleaning device of the utility model has the same beneficial effects because it adopts the above-mentioned sewage tank.

[0016] Other features and advantages of the present invention will be described in detail in the subsequent specific implementation section. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] Please refer to the attached Figure 1-4 As shown, a water-absorbing cleaning device provided by an embodiment of the utility model includes a sewage tank, which is used to hold sewage sucked up after washing and mopping the surface to be cleaned; the water-absorbing cleaning device may also include a clean water tank, which is used to provide clean water required for washing and mopping the surface to be cleaned. The water-absorbing cleaning device may be a common floor scrubber, fabric scrubber, glass scrubber, sweeping robot, etc. on the market.

[0025] The sewage tank includes a box body 2 and a box cover 1, wherein the box cover 1 is provided at the upper end of the box body 2, and a partition 11 is provided at the lower end of the box cover 1, wherein the partition 11 extends into the upper area in the box body 2 to divide the upper area into a front area 10 and a rear area 20, and a sewage suction pipe 21 is provided in the box body 2, wherein the sewage suction pipe 21 extends from the lower end of the box body 2 into the rear area 20 at the upper end of the box body 2, and the partition 11 is provided with a blocking portion 12 on the side facing the rear area 20, wherein the blocking portion 12 is set at a distance from the lower end of the box cover 1 and at least protrudes to the upper area of ​​the sewage suction pipe 21. It can be understood that the distance between the blocking portion 12 and the lower end of the box cover 1 is always greater than 0, that is, the blocking portion 12 is always a certain distance lower than the lower end of the box cover 1.

[0026] The sewage tank of the utility model is provided with a blocking portion 12 on the partition portion 11. When the tank cover 1 is placed on the tank body 2, the blocking portion 12 can naturally surround the sewage suction pipe 21, thereby blocking the sewage suction pipe 21 to limit the height of the sewage impact in the sewage suction pipe 21, thereby preventing sewage and debris from approaching the air suction port 13. The utility model has a simple structure and can effectively reduce the probability of sewage and debris entering the air suction port 13 and contaminating the HEPA filter 3, while not increasing the assembly process of the existing sewage tank.

[0027] The box body 2 and the sewage suction pipe 21 are designed in an integrated manner. Since the enclosure 12 is arranged on the partition 11, the sewage suction pipe 21 can be arranged as a straight pipe. Thus, the integrated design of the box body 2 and the sewage suction pipe 21 facilitates demolding during casting, making the integrated design of the box body 2 and the sewage suction pipe 21 possible. The enclosure 12 and the partition 11 are designed in an integrated manner, which not only reduces the installation of the enclosure 12, but also completes the assembly and alignment of the enclosure 12 and the sewage suction pipe 21 by covering the box cover 1, so the assembly process is simple.

[0028] The lower end of the box cover 1 is provided with an air suction port 13, and the air suction port 13 is located on one side of the front area 10. The box cover 1 is provided with an air suction channel 14, and the air suction channel 14 is connected to the air suction port 13, and a HEPA filter 3 is arranged in the air suction channel 14. Usually, the water suction cleaning equipment uses a suction motor to provide suction force to form an air suction airflow in the air suction channel 14, and the gas in the sewage tank is sucked out from the air suction port 13, so that a negative pressure is formed in the sewage tank to suck the sewage. Since the air suction port 13 is arranged at the lower end of the box cover 1, and the sewage sucked out by the sewage suction pipe 21 is blocked by the enclosure 12, the distance from the air suction port 13 becomes farther, so the probability of sewage and debris approaching the air suction port 13 can be effectively reduced.

[0029] The enclosure 12 is set to be U-shaped, so that the enclosure 12 protrudes to the upper area and the left and right areas of the sewage suction pipe 21. The enclosure 12 is set to be U-shaped, and the upper area of ​​the enclosure 12 can be used to block the sewage flushed out of the sewage suction pipe 21, and then the left and right areas of the enclosure 12 can be used to guide the blocked sewage (and debris) so that they flow quickly to the bottom of the sewage tank, thereby having a good water blocking and water guiding effect. In addition, the U-shaped enclosure 12 also has a certain anti-backflow effect, that is, when the sewage tank is tilted during use, it can prevent the water in the sewage tank from flowing back to the sewage suction pipe 21 to a certain extent. Specifically, the height of the enclosure 12 at least protrudes to exceed the radial 2 / 3 of the sewage suction pipe 21 away from the partition 11.

[0030] In summary, the sewage tank of the utility model has a simple structure, can effectively reduce the probability of sewage and debris entering the air inlet 13 and contaminating the HEPA filter 3, and does not increase the assembly process of the existing sewage tank. The water-absorbing cleaning device of the utility model has the same beneficial effect because it uses the above-mentioned sewage tank.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
