Description

Technical Field

[0001] The present invention relates to the technical field of floor cleaning machines, and particularly to a separation structure for a sewage recovery tank of a household floor cleaning machine. Background Art

[0002] A floor washer is a cleaning device used to clean dirt on the floor. The cleaning module in the floor washer can spray water onto the floor through a nozzle while sweeping the floor, and then collect the sewage and dirt into the sewage tank, thereby achieving the cleaning of the floor. A solid-liquid separation device is arranged in the sewage tank of the floor washer to separate the sewage and dirt in the sewage tank. After the space in the sewage tank is full, the solid-liquid separation device is taken out and the dirt on the solid-liquid separation device is poured out, and then the sewage in the sewage tank is poured out, so as to achieve the separate discharge of sewage and dirt.

[0003] When the floor cleaning machine cleans some special media (such as a large amount of liquid such as tomato sauce and soy sauce), the inhaled liquid contains a large amount of sodium components, and the inhaled liquid splashes and diffuses in the sewage recovery tank of the cleaning machine, which will cause the cleaning machine to falsely trigger a water full warning and affect the normal use of the cleaning machine. Summary of the Invention

[0004] The purpose of the present invention is to provide a separation structure for a sewage recovery tank of a household floor cleaning machine, which can effectively prevent the recycled wastewater from splashing and diffusing in the sewage tank, thereby effectively preventing the cleaning machine from falsely triggering a water full warning and avoiding affecting the normal use of the cleaning machine.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solution: A separation structure for a sewage recovery tank of a household floor cleaning machine, comprising: a recovery tank body, a recovery tank upper cover, and a solid-liquid separator. A conduit is arranged on the bottom surface of the recovery tank body. The recovery tank upper cover is detachably installed on the recovery tank body. The solid-liquid separator is sleeved on the conduit, and the top of the solid-liquid separator contacts the recovery tank upper cover. The solid-liquid separator includes a wire mesh frame body, a lower fence, and an upper baffle. An arc-shaped guiding surface is arranged at the top of the wire mesh frame body. The lower fence is detachably installed on the wire mesh frame body. The upper baffle is detachably installed on the wire mesh frame body. The position of the upper baffle corresponds to the arc-shaped guiding surface. At least one first insertion block is arranged at the top of the upper baffle. A first through hole corresponding to the first insertion block is arranged on the top surface of the wire mesh frame body. Supporting plates are arranged on a pair of opposite side walls of the wire mesh frame body. The side plates of the upper baffle are placed on the supporting plates. A liquid level sensor is arranged on the recovery tank upper cover.

[0006] As a further description of the above technical solution:

[0007] A flow disturbing plate is arranged on the arc-shaped guiding surface.

[0008] As a further description of the above technical solution:

[0009] A support plate is further provided on the grid body, and the support plate contacts the lower side of the top surface of the upper baffle.

[0010] As a further description of the above technical solution:

[0011] The end of the support plate extends below the first through hole.

[0012] As a further description of the above technical solution:

[0013] Insertion columns are provided on the side wall of the lower fence, and insertion holes corresponding to the insertion columns are provided on the grid body.

[0014] As a further description of the above technical solution:

[0015] A groove is provided on the lower fence.

[0016] As a further description of the above technical solution:

[0017] A plurality of strip holes arranged along the height direction of the lower fence are provided on the lower fence.

[0018] As a further description of the above technical solution:

[0019] A Hepa component is provided on the top of the upper cover of the recycling box.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0021] 1. In the present invention, the solid-liquid separator in the sewage recycling box is composed of three parts: a grid body, a lower fence, and an upper baffle. The grid body and the lower fence cooperate to filter solid waste. The setting of the upper baffle prevents sewage from directly spraying onto the recycling box body, causing splashing and residue. Instead, the splashing and residue are restricted within the solid-liquid separator, thereby effectively preventing the wastewater containing a large amount of sodium components from splashing and spreading in the sewage tank, making the liquid remain more on the solid-liquid separator rather than on the recycling box body, thus effectively avoiding the false triggering of the water full warning by the cleaning machine and preventing it from affecting the normal use of the cleaning machine.

[0022] 2. In the present invention, a spoiler is provided on the arc-shaped guide surface. The spoiler can separate the liquid drawn from the conduit, prevent the liquid from concentrating on the central part of the upper baffle, and reduce the liquid splashing ability.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figures 1-5, the present invention provides a technical solution: a separation structure for the sewage recovery tank of a household floor cleaning machine, including: a recovery tank body 1, a recovery tank upper cover 2, and a solid-liquid separator 3. A conduit 11 is provided on the bottom surface of the recovery tank body 1. The recovery tank upper cover 2 is detachably installed on the recovery tank body 1. The solid-liquid separator 3 is sleeved on the conduit 11, and the top of the solid-liquid separator 3 contacts the recovery tank upper cover 2. The solid-liquid separator 3 includes a grid frame body 31, a lower fence 32, and an upper baffle 33. An arc-shaped guiding surface 311 is provided at the top of the grid frame body 31. The lower fence 32 is detachably installed on the grid frame body 31, and the upper baffle 33 is detachably installed on the grid frame body 31. The position of the upper baffle 33 corresponds to the arc-shaped guiding surface 311. At least one first insertion block 331 is provided at the top of the upper baffle 33, and a first through hole 312 corresponding to the first insertion block 331 is provided on the top surface of the grid frame body 31. Supporting plates 313 are provided on a pair of opposite side walls of the grid frame body 31, and the side plates 332 of the upper baffle 33 are placed on the supporting plates 313. A liquid level sensor 4 is provided on the recovery tank upper cover 2.

[0034] A flow disturbing plate 314 is provided on the arc-shaped guiding surface 311. The flow disturbing plate 314 can separate the liquid drawn from the conduit 11 to prevent the liquid from concentrating on impacting the central part of the upper baffle 33 and reduce the liquid sputtering ability.

[0035] A supporting plate 315 is further provided on the grid frame body 31. The supporting plate 315 contacts the lower side of the top surface of the upper baffle 33 to effectively support the upper baffle 33 and prevent the upper baffle 33 from being loosely installed.

[0036] The end of the supporting plate 315 extends to the lower part of the first through hole 312 to prevent the upper baffle 33 from deforming and being loosely installed, avoid the upper baffle 33 from detaching from the grid frame body 31, and ensure the liquid anti-sputtering effect.

[0037] Insertion posts 321 are provided on the side wall of the lower fence 32, and insertion holes 316 corresponding to the insertion posts 321 are provided on the grid frame body 31 to realize the detachable installation of the lower fence 32.

[0038] A groove 322 is provided on the lower fence 32 to facilitate grasping the lower fence 32 from the outside and facilitate removing the lower fence 32.

[0039] A plurality of strip-shaped holes 323 arranged along the height direction of the lower fence 32 are provided on the lower fence 32 to reduce the self-strength of the lower fence 32 and facilitate deforming the lower fence 32, thereby facilitating the removal of the lower fence 32.

[0040] A Hepa component 5 is provided on the top of the recovery tank upper cover 2 to filter the gas discharged from the sewage tank and avoid polluting the environment.

[0041] Working principle: Sewage enters the sewage recovery tank from conduit 11 and, guided by the arc-shaped guiding surface 311 at the top of the grid body 31 in the solid-liquid separator 3, enters the solid-liquid separator 3. The solid-liquid separator 3 screens out the solid waste in the sewage. The solid-liquid separator 3 in the sewage recovery tank consists of three parts: the grid body 31, the lower fence 32, and the upper baffle 33. The grid body 31 and the lower fence 32 cooperate to filter solid waste. The setting of the upper baffle 33 prevents the sewage from directly spraying onto the recovery tank body 1, causing splashing and residue. Instead, the splashing and residue are restricted within the solid-liquid separator 3, thereby effectively preventing the wastewater containing a large amount of sodium components from splashing and spreading in the sewage tank, allowing more liquid to remain on the solid-liquid separator 3 rather than on the recovery tank body 1, thus effectively avoiding the false triggering of the water full warning by the cleaning machine and preventing it from affecting the normal use of the cleaning machine.
