Description

TECHNICAL FIELD

[0001] The present application relates to a separation module, a cleaning machine and a working method thereof, and a storage medium. BACKGROUND

[0002] A separation module and a fan module are arranged in a cleaning machine such as a scrubber, a vacuum cleaner or a sweeper. Under the negative pressure of the fan module, the separation module separates the sewage and particles picked up by the sweeping and mopping module from the air, retains the sewage and particles, and discharges clean air. In order to achieve the filtering and separating effect, a filter element is usually arranged in the separation module. However, the filter element cannot be replaced in time because it is arranged inside the structure, so that the filter element can normally play the filtering role for a short time.

[0003] In order to solve the cleaning problem of the filter element, a separation device for a cleaning machine is disclosed in the Chinese Utility Model Patent No. CN219206753U (Application No. 202222271671.4), which can clean the filter element. Specifically, the separation device includes a housing having a chamber inside, an air inlet and an air outlet communicating with the chamber, and the air outlet is located on the top of the chamber; a first filter element for separating at least dust and liquid, shielding the air outlet; a water inlet opening on the housing and communicating with the chamber; and the first filter element is located on the flow path of the water flow flowing out of the water inlet. The water flow entering through the water inlet cleans the first filter element, avoids the first filter element from being unable to achieve the filtering purpose due to blockage after long-term use, and improves the service life of the first filter element. Usually, the first filter element is provided with multiple layers, and the water flow flows through the first filter element at a slow flow rate, so that the cleaning effect of the filter element is limited, the cleaning is not thorough, and a large amount of dirt remains on the filter element. During long-term use, the accumulation of dirt on the filter element will increase, which affects the ventilation performance of the first filter element and further affects the normal operation of the dust collection work.

[0004] In addition, when the cleaning machine is working, large particles of garbage inevitably enter the separation module, and the large particles of garbage will continuously hit the wall surface of the separation module, thereby generating a large noise. The cleaning machine in the prior art does not make any treatment for this situation, which reduces the user experience. SUMMARY

[0034] The application will be further described in detail below with reference to the embodiments of the drawings.

[0035] As shown in the drawings, Figs. 1-3 the present embodiment relates to a separation module and a cleaning machine applied with the separation module.

[0036] The cleaning machine comprises a matched machine body and a base station. The machine body comprises a machine shell 200, a fan 100 arranged in the machine shell 200, and a separation module. The separation module is detachably embedded in the machine shell 200. After the separation module is installed in the machine shell 200, the top of the separation module is flush with the top of the machine shell. In order to facilitate the dismounting operation of the separation module on the machine shell, a notch is arranged at the edge of the separation module, which can be inserted by the user's fingers, thereby facilitating the user to dismount the separation module from the machine shell.

[0037] The separation module is connected with the fan 100, thereby forming a negative pressure in the separation module, so as to realize the collection of ground sewage, garbage and other pollutants by the separation module.

[0038] As shown in the drawings, Fig. 1 and Fig. 2As shown, the separation module in the embodiment includes a separation box 1, which has a chamber inside for collecting sewage, garbage and the like during the cleaning process. An air outlet is formed on the top of the separation box 1, which is arranged towards the top of the cabinet 200, and a filter element 2 is arranged on the air outlet, which can filter dust and sundries in the air flow discharged through the air outlet, to ensure the cleanliness of the air flow. A negative pressure port 11 connected with the fan 100 and a sewage suction port 12 for sucking garbage are also formed on the separation box 1, the negative pressure port 11 is formed on the side wall of the separation box 1, and the separation box 1 is connected with the inlet of the fan 100 through the negative pressure port 11. The sewage suction port 12 is arranged at the side wall of the separation box 1 along the tangential direction of the separation box 1, and is connected with the floor brush module area on the machine body through a communication pipeline, so as to form an air flow passage. Under the negative pressure of the fan 100, the garbage on the ground is sucked into the separation box 1 through the sewage suction port 12, and under the filtering action of the filter element 2, the solid garbage, sewage and other garbage are separated from the air flow and remain in the separation box 1, and the separated gas is discharged from the air outlet to the outside air through the filter element 2.

[0039] During the process of discharging the air flow, dust and other pollutants will inevitably be mixed in the air flow, and under the filtering action of the filter element 2, the dust will accumulate and stay on the filter element 2. After a long time, the amount of dust on the filter element 2 will increase, and accordingly the filter element 2 needs to be cleaned. Since the dust accumulates on the inner surface of the filter element 2 facing the chamber of the separation box 1, washing the filter element 2 from the outside has very limited cleaning effect, and after cleaning, bacteria will breed due to the residual water and un-washed dust on the filter element 2, and the filter element 2 will stink.

[0040] In order to solve the problem of cleaning effect of the filter element 2, the filter element 2 in the embodiment is reversibly embedded in the air outlet. When the filter element 2 needs to be washed, the filter element 2 is turned over so that the inner surface of the filter element 2 faces outward, so that the user can place the filter element 2 under water for washing. Since the main filtering surface of the filter element 2 on which the dust accumulates can be directly washed, the cleaning effect of the filter element 2 can be greatly improved. When cleaning the filter element 2, the entire floor brush module can be removed from the cabinet for the convenience of the user to hold.

[0041] In order to ensure the stability of the position of the filter element 2 during work and to realize automatic turning over of the filter element 2, a driving mechanism 3 for driving the filter element 2 to turn over is arranged on the separation box 1, and the driving mechanism 3 is connected with the filter element 2. The driving mechanism 3 includes a motor 31, a worm 32 connected with the driving end of the motor 31, a worm gear 33 meshingly connected with the worm 32, and the worm gear 33 is connected with the filter element 2. When the filter element 2 is driven, the motor 31 works, and then drives the worm 32 to rotate, based on the transmission action of the worm 32, the worm gear 33 rotates, and then drives the filter element 2 to turn over, and then turns over the inner surface of the filter element 2 to the outside, which is convenient for cleaning.

[0042] In addition, when the filter element 2 is cleaned by being turned over, the user cannot control the holding direction of the cleaning machine, so water may flow into the fan through the negative pressure port 11, which may cause damage to the fan during subsequent operation of the cleaning machine. In order to avoid this problem, in the present embodiment, a cover plate 4 is arranged on the separation box 1 and is opened and closed in sliding manner relative to the negative pressure port 11. The cover plate 4 is in transmission connection with the driving mechanism 3. When the driving mechanism 3 drives the filter element 2 to turn over, the cover plate 4 is also driven to slide and close the negative pressure port 11, so as to avoid water flowing into the fan 100.

[0043] The cover plate 4 is in transmission connection with the driving mechanism 3 through a transmission assembly 5. The transmission assembly 5 includes a lead screw 51 connected to the end of the worm 32, a moving seat 52 screwed on the lead screw 51, and a pusher 53 connected with the moving seat 52. The pusher 53 is connected with the end of the cover plate 4. In the present embodiment, when the motor 31 rotates forward, the worm 32 and the worm gear 33 drive the filter element 2 to turn over. Correspondingly, the worm 32 drives the lead screw 51 to rotate. Based on the rotation of the lead screw 51, the moving seat 52 moves in the direction of closing the cover plate 4, and in turn drives the pusher 53 to move in the direction of closing the cover plate 4. The cover plate 4 moves synchronously with the pusher 53, and in turn closes the negative pressure port 11. When the filter element 2 is washed with the negative pressure port 11 closed, the washing effect of the filter element 2 is ensured, and the safety of the fan 100 is ensured. When the filter element 2 needs to be reset, the motor 31 reverses, which in turn drives the filter element 2 to rotate and reset, and also drives the cover plate 4 to move in the direction of opening the negative pressure port 11. When the filter element 2 is reset, the cover plate 4 completely opens the shielding of the negative pressure port 11.

[0044] In addition, in order to ensure the reliable movement of the pusher 53, a guide seat 54 is arranged on the separation box 1, and the pusher 53 is movably limited on the guide seat 54. In order to ensure the reliable movement of the cover plate 4, a guide groove 111 is arranged on the outer periphery of the negative pressure port 11, and the cover plate 4 is movably limited in the guide groove 111.

[0045] When the cleaning machine is working, there will inevitably be large-particle garbage on the ground. When the large-particle garbage is sucked into the separation box 1, it will produce a large noise due to the collision with the wall of the separation box 1. In the embodiment, a detection assembly for detecting large-particle garbage is arranged in the separation box 1. The selection of the detection assembly is determined according to the needs, for example, a camera, a light sensor, etc. can be selected. In the embodiment, the detection assembly includes two first and second sound wave sensors arranged in two directions, each group of sound wave sensors includes a sound wave transmitter and a sound wave receiver arranged oppositely. When large-particle garbage enters the separation box 1 during detection, the sound wave signal received by the sound wave receiver will change, so that whether large-particle garbage enters the separation box 1 is determined based on the change of the sound wave signal. In the embodiment, when large-particle garbage enters the separation box 1, the suction of garbage is stopped, and a switch valve is arranged on the sewage suction port 12, so that the opening and closing control of the sewage suction port 12 can be realized by controlling the opening and closing action of the switch valve. When the switch valve is closed, the garbage collection work cannot be performed.

[0046] The working method of the foregoing cleaning machine is that when any one of the following conditions is met, the driving mechanism 3 is controlled to drive the filter element 2 to overturn, so that the inner surface of the filter element 2 is turned outward, and the user washes the filter element 2.

[0047] Condition one: the cumulative working time T of the cleaning machine is greater than or equal to the set time threshold T0. Specifically, each time the cleaning machine starts working, the cumulative timing is started, and when the cleaning machine stops working, it is determined whether the cumulative working time T of the cleaning machine is greater than or equal to the set time threshold T0. When the first condition is met, the driving mechanism 3 is controlled to drive the filter element 2 to overturn to realize the washing of the filter element 2, and then the current cumulative working time is cleared, so that the cumulative timing can be restarted.

[0048] Condition two: the negative pressure value of the negative pressure port 11 is greater than or equal to the negative pressure threshold corresponding to the current working power of the fan. This condition is used to determine whether the filter element 2 is blocked. When the negative pressure value of the negative pressure port 11 is greater than or equal to the negative pressure threshold corresponding to the current working power of the fan, it indicates that the filter element 2 is blocked, and the filter element 2 needs to be washed to restore the filtering capacity. Of course, after the driving mechanism 3 drives the filter element 2 to overturn to wash the filter element 2, the current cumulative working time of the cleaning machine according to the first condition is cleared.

[0049] Condition three: the filter core 2 flushing operation signal is acquired. In order to meet the user's self-cleaning needs, an operation key can also be arranged on the cleaning machine, the user operates the filter core 2 flushing operation key, and then issues the filter core 2 flushing instruction, so that the filter core 2 is controlled to be flipped under the condition three, and the user's self-cleaning needs for the filter core 2 are met. Correspondingly, the accumulated working time of the cleaning machine under the condition one is reset after the filter core 2 is flipped by the driving mechanism 3 and the filter core 2 flushing work is completed.

[0050] In addition, when the cleaning machine is working, the detection assembly detects whether large-particle garbage is sucked into the separation box 1, if yes, the suction port 12 is controlled to be closed, so that the channel for garbage into the separation box 1 is closed, and the garbage suction work is stopped accordingly, so as to avoid the impact of airflow on the large-particle garbage, and the noise caused by the impact of the large-particle garbage in the separation box 1 is avoided accordingly. Then, the machine body is controlled to move to the base station to perform the sewage discharge work in the separation box 1, and the large-particle garbage is discharged, so as to completely avoid the noise caused by the large-particle garbage in the separation box 1.

[0051] The application also relates to a computer readable storage medium, which stores computer instructions for making a computer execute the working method of the cleaning machine.

[0052] The separation module in the application is provided with the driving mechanism 3 for driving the filter core 2 to flip, so that the filter core 2 can be flipped by the driving of the driving mechanism 3 during use, the inner surface of the filter core 2 on which the dirt is accumulated is outward, and then the filter core 2 is convenient for the user to clean, the cleaning effect of the filter core 2 is greatly improved, the performance of the filter core 2 is improved, and the service life of the filter core 2 is prolonged.

[0053] The cleaning machine applied with the separation module improves the separation effect of the separation module and improves the use experience.

[0054] The working method of the cleaning machine can automatically realize the flipping of the filter core 2, and then the user can clean the filter core 2 conveniently, the cleaning degree of the filter core 2 is improved, and the service life of the filter core 2 is prolonged.
