Description

Technical Field

[0001] The present invention relates to the technical field of floor scrubbers, and in particular to a floor scrubber sewage tank capable of achieving secondary separation of water and gas. Background Art

[0002] A household floor scrubber primarily consists of a main unit and a floor brush. The main unit is equipped with a water tank (to supply water to the drum) and a wastewater tank (to collect wastewater). It also features a controller, a spray device, a drum motor for controlling the drum, a suction device, and a main motor for controlling the suction device. The floor brush primarily houses the drum and a drainage channel for cleaning the floor.

[0003] Although existing floor scrubber wastewater tanks use solid-liquid separators to separate wastewater from solid waste, these tanks typically contain only a single chamber—the wastewater, air (vacuum suction), and monitoring device share the same chamber. If the water-air separation within the tank is ineffective, the recovered wastewater may not reach the set point, causing the air to cause the liquid level to fluctuate. This can cause the detection device to alert the user that the tank is full, resulting in a false alarm and affecting the accuracy of water level detection. Summary of the Invention

[0004] The purpose of the present invention is to provide a floor scrubber sewage tank that can achieve secondary separation of water and air, realize secondary separation of sewage and air in the tank, avoid liquid level fluctuation caused by airflow, and ensure accurate water level detection.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a sewage tank of a floor washing machine that can realize secondary separation of water and gas, comprising: a box body and an upper cover, a sewage inlet pipe is provided in the box body, a sewage inlet is provided on the top of the sewage inlet pipe, a sewage collecting chamber is provided in the box body, a blocking piece is provided in the box body, the bottom of the blocking piece extends to below the sewage inlet, the top of the blocking piece extends to above the sewage inlet, the interior of the blocking piece forms an independent cavity, the upper part of the independent cavity is connected to the sewage collecting chamber, and the lower part of the independent cavity is connected to the sewage collecting chamber, the upper cover is detachably installed on the box body, a water level detection component with a symmetrical independent cavity is provided on the upper cover, the bottom of the water level detection component extends into the independent cavity, a blocking piece is also provided on the bottom surface of the upper cover, the top of the blocking piece extends into the blocking piece, a gap is provided between the blocking piece and the blocking piece, and ventilation holes are also provided on the upper cover.

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

[0007] The enclosure is a plate with a U-shaped cross section, and the enclosure and the inner wall of the box body form an independent cavity.

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

[0009] Two enclosure members are provided in the box.

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

[0011] The two enclosures are symmetrically arranged on both sides of the sewage inlet pipe.

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

[0013] Both ends of the blocking member are provided with bent edges, which abut against the inner wall of the box body.

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

[0015] The blocking member is an arc-shaped plate.

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

[0017] The bending edge is an arc-shaped plate.

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

[0019] A shielding member is provided inside the enclosure, and the position of the shielding member corresponds to the water level detection component. The shielding member includes several parallel and equidistantly arranged baffles, which are arranged tilted downward, and the ends of the baffles are fixedly mounted on the inner wall of the enclosure through connecting rods.

[0020] As a further description of the above technical solution:

[0021] The two adjacent baffles are staggered.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0023] 1. In the present invention, when air enters the sewage collection chamber along with sewage, the water level detection assembly extends into the independent chamber enclosed by the enclosure within the tank. When the sewage stored in the sewage tank submerges the bottom of the enclosure, the bottom of the independent chamber enclosed by the enclosure is sealed by the sewage, preventing air from entering from below. However, due to the gap between the barrier and the enclosure, the upper portion of the independent chamber is connected to the sewage collection chamber, maintaining consistent air pressure and ensuring that the water level within the independent chamber remains consistent with the water level within the sewage collection chamber. With this structure, airflow within the sewage collection chamber cannot affect the water level detection assembly within the independent chamber, achieving secondary water-gas separation.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0036] See also Figure 1-7 The present invention provides a technical solution: a floor scrubber sewage tank capable of realizing secondary separation of water and gas, comprising: a tank body 1 and an upper cover 2, a sewage inlet pipe 11 provided in the tank body 1, a sewage inlet port 111 provided on the top of the sewage inlet pipe 11, a sewage collecting chamber 13 provided in the tank body 1, a blocking member 12 provided in the tank body 1, the bottom of the blocking member 12 extending to below the sewage inlet port 111, the top of the blocking member 12 extending to above the sewage inlet port 111, the interior of the blocking member 12 forming an independent The upper part of the independent cavity is connected to the sewage collection chamber 13, and the lower part of the independent cavity is connected to the sewage collection chamber 13. The upper cover 2 is detachably installed on the box body 1. The upper cover 2 is provided with a water level detection component 21 with a symmetrical position of the independent cavity. The bottom of the water level detection component 21 extends into the independent cavity. A blocking member 22 is also provided on the bottom surface of the upper cover 2. The top of the enclosure 12 extends into the blocking member 22. A gap 23 is provided between the blocking member 22 and the enclosure 12. A ventilation hole 24 is also provided on the upper cover 2.

[0037] The enclosure 12 is a plate with a U-shaped cross section, and the enclosure 12 and the inner wall of the box body 1 form an independent cavity. The structure of the independent cavity is simplified to avoid deformation of the enclosure 12 while ensuring the volume of the sewage collection cavity 13.

[0038] Two enclosure members 12 are provided in the box body 1. Two water level detection components 21 are correspondingly provided to facilitate accurate sewage level detection.

[0039] The two enclosure members 12 are symmetrically arranged on both sides of the sewage inlet pipe 11 to accurately detect the water level in the sewage collection chamber 13 and prevent inaccurate water level detection caused by the tilt of the sewage tank.

[0040] Bending edges 221 are provided at both ends of the blocking member 22 , and the bending edges 221 abut against the inner wall of the box body 1 , thereby effectively shielding the enclosure member 12 .

[0041] The blocking member 22 is an arc-shaped plate that is not easily deformed and reduces the noise caused by airflow impact.

[0042] The bent edge 221 is an arc-shaped plate that fits against the inner wall of the box body 1 , preventing the gas carrying the liquid from entering the independent cavity, thereby further protecting the water level detection component 21 .

[0043] The interior of the enclosure 12 is equipped with a shielding member 3, positioned corresponding to the water level detection assembly 21. The shielding member 3 comprises several parallel and equidistant baffles 31, arranged at an angle downward. The ends of the baffles 31 are fixed to the inner wall of the enclosure 12 via connecting rods 32. The installation of the shielding member 3 reduces the amount of foam that enters the surface of the sewage inside the enclosure 12, thereby preventing it from affecting sewage level detection. The gaps between the baffles 31 do not affect the rise of the water level in the enclosure 12, nor does it affect connectivity.

[0044] Two adjacent baffles 31 are arranged in a staggered manner, that is, when viewed from above, one baffle 31 blocks the other adjacent baffle 31. Figure 7 The gaps in the baffles 31 form a "tortuous" passage, which does not affect the rising water level in the enclosure 12 and can effectively reduce foam.

[0045] Working Principle: When collecting sewage in the floor scrubber's sewage tank, air is drawn into the tank body 1 along with the sewage through the sewage inlet 111 at the top of the sewage inlet pipe 11, creating a water-gas separation space in the sewage collection chamber 13. The specific principle of water-gas separation is as follows: the staggered fit of the enclosure 12 and the blocking member 22 creates an independent chamber within the sewage collection chamber 13 that is connected to the sewage collection chamber 13. The enclosures 12 on both sides of the sewage tank create a "multi-chamber" structure. When air is drawn into the sewage collection chamber along with the sewage, the sewage is collected there and then discharged through the ventilation holes 24 in the upper cover 2. When sewage is collected in the sewage collecting chamber 13, if the amount of sewage is small, the liquid level of the sewage does not exceed the bottom of the enclosure 12 and will not contact the water level detection component 21. The vacuum suction force generated by the floor scrubber to discharge air from the ventilation hole 24 will cause fluctuations in the sewage liquid level in the sewage collecting chamber 13, but will not affect the water level detection; and when the amount of sewage increases and the liquid level of the sewage does not exceed the bottom of the enclosure 12, when the sewage contacts the water level detection component 21, the sewage enters the independent cavity surrounded by the enclosure 12 and the blocking member 22. Since a gap 23 is provided between the blocking member 22 and the enclosure 12, the top of the independent cavity is connected to the sewage collecting chamber 13, so that the air pressure and water level are kept consistent. At the same time, the airflow discharged from the sewage tank cannot affect the liquid level of the sewage in the independent cavity. The principle of communicating vessels is used to achieve secondary separation of sewage and air, thereby avoiding interference of air on the detection device.

[0046] The sewage tank is provided with a multi-cavity structure, so that the liquid level inside the opposite cavity where the water level detection component 21 is located remains stable and is not affected by air discharge. Therefore, whether the water level detection component 21 adopts a metal electrode type or a float type, the accuracy of water level detection can be effectively guaranteed.

[0047] In addition, since the top of the enclosure 12 extends into the blocking member 22, that is, the independent cavity enclosed by the enclosure 12 and the blocking member 22 is connected to the sewage collection chamber 13 through the gap 23 with the opening facing downward, thereby preventing gas or liquid from entering from the side or above, effectively improving the separation effect of the independent cavity and the sewage collection chamber 13, further preventing the liquid level in the independent cavity from fluctuating, and ensuring accurate water level detection.

[0048] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
