DETAILED DESCRIPTION

[0027] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model will be described in detail below. Obviously, the described embodiments are part of the embodiments of the utility model, but not all of the embodiments. Based on the described embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Refer to the following Figures 1 to 6 The technical solutions of some embodiments of the utility model are described.

[0029] The present utility model provides a sewage tank, which can be used in cleaning equipment such as sweeping robots, dust collectors, and floor scrubbers. The main function of the sewage tank is to store sewage generated during the cleaning process. Figure 1 To Attachment Figure 6 The sewage tank includes a sewage tank body 100 and a sewage tank cover 200. The sewage tank cover 200 can be covered on the sewage tank body 100. The local outer wall of the top of the sewage tank body 100 protrudes outward to form a boss 110. The boss 110 is provided with an air outlet 111 and a sewage inlet 112 respectively penetrating the lower surface thereof. The air outlet 111 is connected to the air inlet of the suction motor. The sewage tank also includes a first baffle 300 and a second baffle 400. The first baffle 300 and the second baffle 400 are fixedly connected to the sewage tank body 100 or the sewage tank cover 200. The first baffle 300 and the second baffle 400 are spaced apart on the outer side of the air outlet 111. When the sewage tank cover 200 is covered on the sewage tank body 100, the projections of the first baffle 300 and the second baffle 400 are located on the boss 110 to prevent the sewage in the sewage tank body 100 from entering the suction motor.

[0030] Specifically, the first baffle 300 is disposed on the sewage tank cover 200 , and the second baffle 400 is disposed on the boss 110 . The first baffle 300 and the second baffle 400 are sequentially disposed outside the air outlet 111 along the direction of wind flow.

[0031] The sewage tank of the utility model can block sewage from entering the air outlet 111 by providing the first baffle 300 and the second baffle 400. When the sewage water level in the sewage tank body 100 is too high, the sewage can be blocked in the sewage tank body 100 to avoid being sucked into the suction motor, thereby increasing the service life of the suction motor.

[0032] See attached Figure 5 and attached Figure 6In some embodiments, the sewage tank further includes a third baffle 500, which is fixed to the sewage tank body 100 or the sewage tank cover 200. Specifically, the third baffle 500 is fixed to the sewage tank cover 200, and the left and right sides of the third baffle 500 abut against the side walls of the sewage tank cover 200. When the sewage tank cover 200 is covered on the sewage tank body 100, a projection of a portion of the third baffle 500 is located on the boss 110, and a projection of another portion of the third baffle 500 is located in the sewage tank body 100, which is used to separate the air outlet 111 and the sewage inlet 112. By providing the third baffle 500, the sewage entering the sewage tank body 100 from the sewage inlet 112 can be prevented from directly entering the air outlet 111.

[0033] In some embodiments, see the attached Figure 5 and attached Figure 6 The first baffle 300 is connected to the third baffle 500, and the left and right sides of the first baffle 300 respectively abut against the side walls of the third baffle 500 and the sewage tank cover 200, and the bottom side edge of the first baffle 300 is provided with an air inlet groove 310. Specifically, the first baffle 300 can be arranged vertically with the third baffle 500, and the air inlet groove 310 at the bottom side edge of the first baffle 300 can be arranged in a long strip shape. By the left and right sides of the first baffle 300 abutting against the side walls of the third baffle 500 and the sewage tank cover 200 respectively, the probability of sewage entering the air outlet 111 can be reduced, and the air inlet groove 310 is provided at the bottom side edge of the first baffle 300. When the sewage tank cover 200 is covered on the sewage tank body 100, the air inlet groove 310 is formed between the first baffle 300 and the boss 110, so that the air in the sewage tank body 100 can enter the air outlet 111.

[0034] In some embodiments, see the attached Figure 3 and attached Figure 4 The upper surface of the boss 110 is provided with an air outlet 113 corresponding to the air outlet 111. Specifically, the air outlet 113 can be set as a cylinder and has an opening at the top side opposite to the side wall of the sewage tank cover 200. The sewage is not easy to enter the air outlet 113, thereby avoiding being sucked into the suction motor. The upper surface of the boss 110 is provided with a sewage inlet pipe 115 corresponding to the sewage inlet 112. The sewage inlet pipe 115 is connected to the sewage tank body 100. The sewage tank also includes a fourth baffle 600, which is set to be L-shaped. The fourth baffle 600 cooperates with the side wall of the sewage tank cover 200 to surround the air outlet 113. There is a gap between the fourth baffle 600 and the side wall of the sewage tank cover 200 to form an air inlet channel 610. By surrounding the air outlet 113 with the fourth baffle 600, the function of blocking sewage is further improved.

[0035] In some embodiments, see the attached Figure 4The fourth baffle plate 600 forms a notch 620 with the side wall of the sewage tank cover 200. Specifically, a top side edge of the fourth baffle plate 600 parallel to the third baffle plate 500 forms a notch 620 with the side wall of the sewage tank cover 200. By providing the notch 620 and the air inlet channel 610, the extraction of air in the sewage tank body 100 is avoided from being affected.

[0036] In some embodiments, see the attached Figure 4 , the bottom of the second baffle plate 400 abuts against the boss 110, the left and right sides of the second baffle plate 400 abut against the third baffle plate 500 and the fourth baffle plate 600 respectively, and the height of the second baffle plate 400 is lower than the third baffle plate 500 and the fourth baffle plate 600. Specifically, the second baffle plate 400 is arranged on the boss 110, and when the sewage level in the sewage tank 100 rises, it first passes through the blocking of the first baffle plate 300 and then enters the second baffle plate 400. The structural design is reasonable and the water blocking effect is good. At the same time, the height of the second baffle plate 400 is lower than the third baffle plate 500 and the fourth baffle plate 600, which reduces the air outlet area, increases the air discharge speed, and improves the suction capacity.

[0037] In some embodiments, see the attached Figure 5 and attached Figure 6 A fifth baffle 210 is provided on the sewage tank cover 200, and the fifth baffle 210 abuts against the boss 110. The fifth baffle 210 is arranged between the first baffle 300 and the fourth baffle 600. Specifically, the fifth baffle 210 further separates the air inlet channel 610 of the fourth baffle 600, further preventing sewage from directly entering the air outlet 111 from the air inlet channel 610 of the fourth baffle 600.

[0038] In some embodiments, see the attached Figure 3 The boss 110 is provided with a probe assembly 114, and the probe assembly 114 is located between the first baffle 300 and the second baffle 400. Specifically, the top of the probe assembly 114 abuts against the first baffle 300, and the side of the probe assembly 114 abuts against the third baffle 500. The connection method between the probe assembly 114 and the boss 110 is not limited, for example, it can be connected by screws. The probe assembly 114 is used to detect the liquid level of sewage in the sewage tank 100. The probe assembly 114 is set at a position close to the top of the sewage tank, so that the sewage tank 100 can accommodate more sewage, improve the space utilization of the sewage tank 100, and enhance the user experience.

[0039] In some embodiments, the sewage tank cover 200 is provided with a gripping portion 220 for easy access by personnel. Specifically, when the sewage tank cover 200 is placed on the sewage tank body 100, the vertical projection of the gripping portion 220 is located inside the sewage tank body 100, and the gripping portion 220 abuts against the third baffle 500, so that the gripping portion 220 facilitates personnel to take out the sewage tank.

[0040] The process of sewage entering the sewage tank 100 after being blocked by various baffles in the utility model is as follows: specifically, when sewage enters the sewage tank 100 from the sewage inlet 112, due to the blocking effect of the third baffle 500, the sewage directly enters the sewage tank 100 and does not enter the air outlet 111. After the sewage enters the sewage tank 100, the suction effect of the suction motor causes the sewage surface to rise. The third baffle 500 can first block a portion of the water vapor. As the water surface continues to rise, it reaches the first baffle 300 and is blocked by another portion of the water vapor. Another portion of the water vapor enters the second baffle 400 and the fifth baffle 210 through the air inlet slot 310 of the first baffle 300. The second baffle 400 and the fifth baffle 210 continue to block the water vapor. Finally, the remaining sewage enters the fourth baffle 600, which becomes less and less and is difficult to continue to rise, thereby achieving the purpose of blocking the sewage.

[0041] The process of air passing through the obstruction of each baffle in turn and flowing into the air outlet 111 of the utility model is as follows: specifically, the air in the sewage tank can first pass through the air inlet slot 310 of the first baffle 300, and then enter the air outlet nozzle 113 through the air inlet channel 610 formed by the fourth baffle 600 and the sewage tank cover 200. The air can also pass through the second baffle 400 and then enter the air outlet nozzle 113 through the notch 620 of the fourth baffle 600, thereby achieving the purpose of extracting air from the sewage tank.

[0042] When the sewage level of the sewage tank of the utility model embodiment is too high due to improper operation, the water is isolated in the sewage tank body 100 due to the blocking effect of each baffle, which provides more time for the suction motor to shut down, prevents sewage from entering the suction motor, and improves the space utilization of the sewage tank. Moreover, after being blocked by multiple layers of baffles, the air outlet area is reduced, the wind speed is increased, and the suction capacity is improved, so that the cleaning equipment with the sewage tank has higher working efficiency and longer service life.

[0043] The embodiment of the utility model also provides a cleaning device. As shown in the figure, the cleaning device includes a shell and a suction motor arranged in the shell. The cleaning device also includes a sewage tank of any of the above embodiments. Specifically, the sewage tank and the clean water tank are both arranged in the shell, and the shell also includes a sewage suction channel, which is connected to the sewage inlet 112 on the sewage tank body 100, and the sewage is sucked into the sewage tank body 100 through the sewage suction channel through the sewage inlet 112. The air inlet of the suction motor is connected to the air outlet 111 on the sewage tank body 100, which is used to suck the air in the sewage tank body 100 to maintain a negative pressure in the sewage tank body 100. Under the action of the negative pressure, the dirt on the surface to be cleaned is sucked into the sewage tank body 100 through the sewage suction channel, thereby achieving the effect of cleaning the surface. The cleaning device of the embodiment of the utility model can extend the service life of the cleaning device by providing a sewage tank that can improve the effect of blocking sewage from entering the suction motor.

[0044] The above description is intended to be illustrative rather than restrictive, and those skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present disclosure. Moreover, the above examples (or one or more of them) may be used in combination with each other, and it is contemplated that these embodiments may be combined with each other in various combinations or permutations.
