In other words, the sewage and sundries flow downwards and the air flows upwards through the first blocking, so that the separation purpose is realized, and the airflow is also facilitated to flow to the next-stage separation unit.
As shown in fig. 2, a closing member 24 with an opening and closing structure is arranged between the separation cover 2 and the gas-liquid mixture inlet, the closing member 24 is opened when the floor scrubber sucks air, and is closed when the floor scrubber stops sucking air, so that the design structure is compact, the opening/closing time is short, and the response is timely.

As shown in fig. 2 and 4, the centrifugal separation structure includes an air inlet 26 and a centrifugal separation chamber 4, in this example, an air inlet end 5 of a second air inlet pipe 36 is the air inlet 26, a gas-liquid mixture coming from the air inlet 26 enters the centrifugal separation chamber 4 through an air outlet end 6' of the second air inlet pipe 36, and the centrifugal separation chamber 4 separates the gas from the liquid by using a rotational centrifugal force of the gas-liquid mixture, in this example, in order to form centrifugal rotation, a second cyclone 35 is disposed in the second air inlet pipe 36, and the second cyclone 35 guides the gas-liquid mixture coming from the air inlet 26 into the centrifugal separation chamber 4 and forms a cyclone. The cyclone may be formed by other structures, for example, a tangential inlet is provided in the peripheral wall of the centrifugal separation chamber 4, and is in communication with the second air intake duct 36, and the gas-liquid mixture from the second air intake duct 36 is guided to form the cyclone through the tangential inlet. For another example, the centrifugal separation chamber 4 is provided with a cyclone guide vane at the outlet end 6' of the second air inlet pipe 36, and the gas-liquid mixture enters the centrifugal separation chamber 4 through the cyclone guide vane to form centrifugal rotation, thereby realizing centrifugal separation. For example, the bottom of the centrifugal separation chamber 4 is connected with a second air inlet pipe 36, a second cyclone 35 is arranged in the second air inlet pipe 36, and cyclone guide vanes are arranged at the bottom of the centrifugal separation chamber 4 and are denoted as first cyclones, and the gas-liquid mixture from the air inlet sequentially passes through the second cyclone 35 and the first cyclones to enter the centrifugal separation chamber and form cyclones.

Furthermore, as shown in fig. 4, the collecting chamber 11 is provided with a tangential guide surface 13, which is designed tangentially to the rotation circumferential surface of the centrifugal separation chamber, so that a better cyclone entry into the collecting chamber 11 and a better separation result is obtained. Further, as shown in fig. 2, the centrifugal separation chamber 4 is provided with an air outlet pipe 30, and the air outlet pipe 30 is axially sleeved with the centrifugal separation chamber 4, so that air flow formed by the air outlet pipe 30 can flow out of the air outlet pipe 30 upwards and then downwards, which is beneficial to leaving separated sewage in the centrifugal separation chamber 4, and meanwhile, the rotating air flow has enough time to separate and can not be directly discharged. Further, as shown in fig. 2 and 4, the collecting chamber 11 is provided with a baffle 31, and the height of the baffle 31 is higher than the bottom of the collecting chamber 11, so that the rotating air flow entering the collecting chamber 11 can be blocked to a certain extent, which is beneficial to separating sewage and remaining in the collecting chamber 11. Furthermore, as shown in fig. 4, the collecting chamber 11 is provided with a baffle plate 31, in this example, the baffle plate 31 is a component of a rotation circumferential surface of the centrifugal separation chamber 4, the structure is compact, the wall surface of the baffle plate 31 on one side of the centrifugal separation chamber 4 does not affect the cyclone of the centrifugal separation chamber 4, the height of the baffle plate 31 is higher than the bottom of the collecting chamber 11, the centrifugal separation chamber 4 is provided with an air outlet pipe 30, the air outlet pipe 30 is axially sleeved with the centrifugal separation chamber 4, and the height of the baffle plate 31 is higher than the air inlet 26 of the air outlet pipe 30, so that the rotation air flow entering the collecting chamber 11 can be blocked to a certain extent, the sewage can be separated out, and the sewage left in the collecting chamber 11, meanwhile, the separated sewage is not easy to reenter the air outlet pipe 30, thereby guaranteeing the separation performance.
The centrifugal separation cavity 4 utilizes the gas-liquid mixture to rotate centrifugal force to separate gas from liquid, can obtain better separation effect, simultaneously, collect the setting of room 11, collect the room 11 on the one hand and promoted gas-liquid separation, on the other hand makes the sewage that the centrifugation separated concentrate to collect the room 11 fast, greatly improves separation effect, consequently has better gas-liquid separation performance.
The drain port of the collecting chamber 11 is provided with a one-way valve 12, when the centrifugal separation unit works, the drain port is closed by the one-way valve 12, when the centrifugal separation unit stops working, the drain port is opened by the one-way valve 12 to discharge sewage to the sewage bucket through the drain port, so that when the centrifugal separation unit works, the air flow in the sewage bucket 1 can be ensured not to directly enter the centrifugal separation cavity 4 through the drain port, on the other hand, the negative pressure of the centrifugal separation cavity 4 is higher than that of the sewage bucket 1, the negative pressure generated by the fan 32 is used as an efficient suction source, the energy utilization rate is high, the air flow is stronger, and when the centrifugal separation unit stops working, the drain port is opened by the one-way valve 12 to discharge sewage to the sewage bucket 1. In summary, it is advantageous that both the centrifugal separation unit and the sewage tank 1 do not influence each other after the solution according to the invention is applied. In this example, the check valve 12 is a rubber or silica gel valve plate, when the centrifugal separation unit works, the liquid outlet is automatically closed by the check valve 12 by utilizing the pressure difference between the centrifugal separation cavity 4 and the sewage bucket 1, and when the centrifugal separation unit stops working, the check valve 12 is opened unidirectionally along with the reduction or disappearance of the pressure difference, so that sewage is discharged to the sewage bucket 1. Of course, the check valve 12 may have other structures, and the control structure for unidirectional opening may also have other structures, which are applicable to all the requirements of the scheme of the present invention.
As can be seen from the axial arrangement of the separation unit and with reference to the drawings, in this case the drain is located at the bottom of the centrifugal separation chamber 4, so that when the centrifugal separation unit is not in operation, the one-way valve 12 opens the drain and sewage naturally flows to the sewage tank 1, with the shortest path. The bottom arrangement, in combination with the arrangement of the collecting chamber 11, i.e. the liquid drain is located at the bottom of the collecting chamber 11, will achieve better separation and drainage effects.
When the first cyclone is provided at the bottom of the centrifugal separation chamber 4 and the second air inlet duct 36 is connected to the bottom of the centrifugal separation chamber 4, the second air inlet duct 36 serves to increase the distance between the air inlet end 5 and the first cyclone, which is designed to facilitate acceleration of the cyclone, and in addition, to make it difficult for sewage that has been left in the sewage bucket 1 to re-enter the first cyclone or further to the centrifugal separation chamber 4.
Further, the lower side of the bottom of the centrifugal separation chamber 4 is provided with an axial flow passage coaxially arranged in the axial direction of the centrifugal separation chamber 4, i.e., a second air intake pipe 36, the air intake end 5 axially conveys the air-liquid mixture through the axial flow passage, and the air-liquid mixture enters the centrifugal separation chamber from the bottom and/or the peripheral wall of the centrifugal separation chamber. Thus, in combination with the arrangement of the air outlet pipe 30, the air flow is more favorable, the separation effect is improved, the effective utilization of suction negative pressure energy formed by the suction source is facilitated, in addition, the arrangement structure is more favorable, and the structure is more favorable.
Furthermore, the bottom of the centrifugal separation chamber 4 is provided with an inlet for the gas-liquid mixture, a partition is arranged between the inlet and the inlet of the air outlet pipe 30, in this case, the partition is the diffusion cover 37, so that on one hand, the gas-liquid mixture cannot directly flow into the air outlet pipe 30, on the other hand, the gas-liquid mixture can enter the air outlet pipe 30 after cyclone separation is performed in the centrifugal separation chamber 4 as much as possible, the separation efficiency is improved, and on the other hand, when the first cyclone is arranged, the first cyclone can be used as the partition, and the structure is simplified.
Further, an annular partition flow passage is formed between the partition and the inlet of the centrifugal separation chamber 4, so that the flow of the gas-liquid mixture is facilitated. When provided with a first cyclone, the annular spaced flow passages may be adapted to receive the cyclone blades of the first cyclone.
In order to have stronger whirlwind, the annular interval runner can be set to be of a reducing arrangement, for example, the annular interval runner is provided with at least one narrowing section 38, the narrowing section 38 is arranged between the inlets and outlets of the annular interval runner, and the annular runner sections of the inlets and outlets are all larger than the annular runner sections of the narrowing section, so that the airflow can be accelerated by the narrowing section 38, and the annular runner sections of the inlets and outlets are all larger than the annular runner sections of the narrowing section, thereby being beneficial to forming stronger whirlwind.
In addition, in fig. 2, since the cyclone blades of the second cyclone 35 provide a cyclone formation structure, the annular space flow passage does not accommodate the cyclone blades of the first cyclone, and is thus more unobstructed, thus facilitating the flow of the gas-liquid mixture, enhancing the cyclone, and in addition, making the diameter-changing arrangement of the annular space flow passage more effective.
In addition, the inlet of the centrifugal separation chamber 4 is provided with a diffusion cover 37, the diffusion cover 37 is used as the partition part, and the diffusion cover 37 guides the gas-liquid mixture from the second gas inlet pipe 36 to diffuse into the centrifugal separation chamber 4, so that on one hand, stronger whirlwind is formed, on the other hand, the gas flow is smoothly whirlwind in the centrifugal separation chamber 4, on the other hand, the diffusion cover 37 and the partition part are the same component, the structure is simplified, in a word, better separation effect is realized, and meanwhile, the structure is simplified. In this example, the diffuser cap 37 is an inverted umbrella shape.
Examples
