Surface cleaning devices are often provided with multiple cleaning modes, such as a general cleaning mode, a deep cleaning mode, etc., in order to better clean surfaces to be cleaned at different levels of soiling when operating. It is generally believed that increasing the power of the vacuum motor can increase the cleaning effectiveness of the surface cleaning apparatus without changing other conditions. However, the cleaning force of the surface cleaning device is not only determined by the single influence factor of the power of the vacuum motor, and a sewage bucket matched with the power of the vacuum motor is required to be used, and the pipe diameter of a sewage inlet pipe in the sewage bucket and the height of the sewage inlet pipe influence the sewage suction capacity of the vacuum motor. If a slop pail which is not matched with the vacuum motor is used, the situation that the larger the working power of the vacuum motor is, the worse the dirt absorbing capacity of the surface cleaning device is, or the higher the working power of the vacuum motor is, the satisfactory cleaning capacity of a user can be achieved, intolerable noise pollution is caused to the user, and the use experience of the user is influenced.
Disclosure of Invention
The invention aims to solve the technical problem of how to select a proper sewage bucket and a proper vacuum motor, and the surface cleaning device has better dirt suction capacity and improves the cleaning capacity under the combined action of the sewage bucket and the vacuum motor.
In order to achieve the purpose, the invention is realized by the following technical scheme: the utility model provides an effectual surface cleaning device of soil pick-up, includes vacuum motor, clean water bucket, slop pail and organism, be equipped with the cleaning member on the organism and with the relative soil pick-up mouth that sets up of cleaning member, the clean water bucket passes through the supply line and is connected with the organism, vacuum motor passes through slop pail and soil pick-up passageway and soil pick-up mouth intercommunication, the slop pail portion is equipped with the bung, is equipped with filter equipment on the bung, is equipped with into dirty pipe in the slop pail, there is the isolation clearance between the filth export at dirty pipe top and the bung, vacuum motor's rated power is 100W to 300W, just vacuum motor's operating power and the pipe diameter ratio of advancing dirty pipe are 5:1(W/mm) -10:1(W/mm), the ratio of the working power of the vacuum motor to the height of the sewage inlet pipe is 1:1(W/mm) -2:1 (W/mm).
Furthermore, a baffle plate is arranged between the dirt outlet of the dirt inlet pipe and the barrel cover.
Furthermore, the dirt outlet of the dirt inlet pipe and the filtering device are arranged in a staggered mode in the vertical direction.
Further, the sewage outlet of the sewage inlet pipe is arranged towards a direction departing from the filtering device or towards the sewage bucket.
Further, the slop pail is provided with a maximum water level, and the equivalent sewage volume of the slop pail maximum water level is not more than 1/2 of the slop pail volume.
Further, the effective volume of the sewage bucket is 300ml-900 ml.
Furthermore, the rated power of the vacuum motor is 100W-200W, the pipe diameter of the sewage inlet pipe is 10mm-40mm, and the height of the sewage inlet pipe is 50mm-200 mm.
Furthermore, the rated power of the vacuum motor is 200W-300W, the pipe diameter of the sewage inlet pipe is 20mm-60mm, and the height of the sewage inlet pipe is 100mm-300mm
Further, the position of the sewage outlet is more than 30mm above the highest water level line of the sewage bucket.
Further, the pipe diameter of the sewage inlet pipe is gradually reduced from the bottom of the sewage inlet pipe to the top of the sewage inlet pipe.
In conclusion, the invention has the following beneficial effects:
the sewage outlet of the sewage inlet pipe is positioned between the barrel covers, an isolation gap exists, so that sewage is upwards moved along the sewage inlet pipe, a space continuously upwards moves is reserved after the sewage outlet is separated, the sewage continuously moves towards the barrel cover after being separated from the sewage outlet, the speed is gradually reduced, and the sewage strikes the barrel cover or a baffle between the barrel cover and the sewage inlet pipe after moving for a period of time. The dirt separated from the dirt outlet moves on the isolation gap between the dirt outlet and the barrel cover, and the solid dirt with large mass moves towards the barrel cover for a period of time under the action of gravity and then turns to move towards the bottom of the barrel body to be finally stored in the sewage barrel body, and partial dirt moves towards the barrel cover, and the speed is gradually reduced in the moving process to finally impact the barrel cover at a relatively low speed or impact the baffle after the dirt moves towards the barrel cover for a period of time between the dirt outlet of the dirt inlet pipe and the barrel cover to realize gas-liquid separation. The gas-liquid separation takes place after the filth takes place to strike, and gaseous by the bung loss go out, and liquid strikes the bung and moves and is accomodate in the slop pail to staving bottom. Meanwhile, the movement speed of the gas-liquid mixture in the isolation gap is gradually reduced, the impact speed of the dirt is low, the range of splashing to the four places after the impact is limited, and the phenomenon that the liquid is splashed out by a barrel cover to wet the HEPA and reduce the service life of the HEPA or even splashed into the vacuum motor to damage the vacuum motor is avoided.
The vacuum motor with the rated power of 100W-300W is selected, and the sewage bucket matched with the vacuum motor is selected, so that the ratio of the working power of the vacuum motor to the pipe diameter and the height of the sewage inlet pipe in the sewage bucket is always kept in a limited range in the working process of the surface cleaning device, the power loss of the vacuum motor is reduced, and the cleaning and dirt collecting capabilities of the surface cleaning device are improved. On one hand, the pressure change speed in the sewage bucket is matched with the speed of the sewage coming out from the sewage outlet through the sewage inlet pipe to achieve a better sewage suction effect; on the other hand, the sewage removed from the sewage outlet moves according to a specified path, and is stored in the sewage bucket after being subjected to solid-liquid separation by the gas-liquid separation and filtration device, so that the problem that the service life of the vacuum motor is reduced because the sewage enters the vacuum motor without being entrained by the air flow is avoided.
If the ratio of the working power of the vacuum motor to the pipe diameter of the sewage inlet pipe is too high, and the ratio of the working power of the vacuum motor to the height of the sewage inlet pipe is in a proportional range, the air pressure in the sewage bucket is reduced quickly, the air flow rate is high, the suction force generated by the vacuum motor through the sewage suction port is increased, external sewage enters the sewage suction channel quickly, but the flow speed of the sewage entering the sewage inlet pipe is reduced under the control of the pipe diameter of the sewage inlet pipe due to the fact that the pipe diameter of the sewage inlet pipe is small, the speed of the sewage coming out of the sewage outlet at the top of the sewage inlet pipe is smaller than the speed of the sewage entering the sewage suction channel through the sewage suction port, so that partial sewage is accumulated in the sewage suction channel after the surface cleaning device works for a period of time, the sewage suction channel is blocked, and the sewage suction capacity of the surface cleaning device, which cannot flow outside air to the inner surface cleaning device of the sewage bucket through the sewage suction channel, is remarkably reduced or even lost, if larger solid particles exist on the surface to be cleaned, the solid particles enter the sewage suction channel from the sewage suction port, and if the diameter of the solid particles is larger than or equal to the pipe diameter of the sewage inlet pipe, the sewage suction capability of the surface cleaning device is directly blocked by the sewage inlet pipe is lost. The problem that the surface cleaning device is scrapped in advance and the problem that the problem after sale is frequent due to the fact that the dirt absorbing pipeline is difficult to disassemble and the cleaning user cannot independently complete the disassembling and cleaning work of the blocked dirt absorbing channel is solved.
The ratio of the working power of the vacuum motor to the height of the sewage inlet pipe meets the proportion requirement, if the ratio of the working power of the vacuum motor to the pipe diameter of the sewage inlet pipe is too low, the path of the sewage bucket communicated with the external air through the sewage inlet pipe is large, so that the air pressure in the sewage bucket is slowly reduced in the process of vacuumizing the sewage bucket by the vacuum motor, and the air flow rate generated by negative pressure and flowing from the outside of a sewage suction port to a sewage suction channel is reduced, so that the suction force of the vacuum motor to sewage is reduced. The suction force of the vacuum motor on the surface to be cleaned and the dirt on the cleaning piece is weakened, the dirt cannot be driven to climb to the dirt outlet at the top of the dirt inlet pipe along the dirt inlet pipe, and the dirt is collected into the sewage bucket after being separated from the dirt inlet pipe. Even if the dirt still can finally be collected to the slop pail, because the suction weakens the dirt collection speed and the dirt collection volume also greatly reduced of surface cleaning device to treat the clean surface, to the air current that the volume is great, the great filth of quality can not be produced by the vacuum motor and wrap up in the dirt suction channel with the fingers, and some filths can't be handled and still stay in the surface of treating, can't satisfy user's clean demand. On the other hand, for small and light dirt, the dirt collection amount per unit time of the surface cleaning device is reduced due to the reduction of the suction force, and when a user drives the surface cleaning device at a normal walking speed to clean the surface to be cleaned, the cleaning of the designated surface to be cleaned cannot be completed within a limited residence time, so that the cleaning effect is poor. The need to increase the operating power of the vacuum motor to increase the cleaning capacity of the surface cleaning apparatus increases the noise generated by the vacuum motor during operation, which can cause confusion to the user and waste of electrical energy.
The ratio of the working power of the vacuum motor to the pipe diameter of the sewage inlet pipe is in a proportional range, if the ratio of the working power of the vacuum motor to the height of the sewage inlet pipe is too high, the height of the sewage inlet pipe is relatively low, on one hand, the highest water level line of the sewage bucket is lower than the sewage outlet of the sewage inlet pipe, and the height of the sewage inlet pipe is relatively low, so that the maximum sewage liquid amount which can be contained in the sewage bucket is reduced, and the requirement of a user for completing one whole-house cleaning work cannot be met, and the user needs to pour the sewage bucket for multiple times in the cleaning process; on the other hand, the sewage with larger distance between the sewage outlet of the sewage inlet pipe and the barrel cover or the baffle plate continuously moves upwards after being separated from the sewage outlet, and does not impact the barrel cover or the baffle plate, namely, the sewage moves towards the bottom of the barrel body under the action of gravity, and the sewage is not subjected to gas-liquid separation.
The operating power of vacuum motor and the pipe diameter ratio of sewage inlet pipe are in the proportion scope, if the operating power of vacuum motor and the height ratio of sewage inlet pipe are low excessively, then the height that the filth needs to climb from the sewage suction port to the filth export is great, and the suction force that the vacuum motor provided probably can't satisfy the filth and can't be accomodate into the slop pail by the surface of treating to clean to the filth export highly overcome the energy that the gravity needs so the filth in the sewage suction passageway can't only make the filth in the sewage suction passageway drunkenness. After the surface cleaning device works for a period of time, the surface cleaning device cannot be separated from the dirt outlet and the dirt stored in the sewage barrel blocks the dirt suction channel, so that the airflow cannot smoothly enter the dirt suction channel from the outside of the surface cleaning device, and the cleaning force of the surface cleaning device is reduced due to the reduction of the dirt suction capability of the surface cleaning device; on the other hand, the relatively high sewage inlet pipe enables an isolation gap between the sewage outlet and the barrel cover to be small, firstly, the ascending space of the sewage in the direction of the barrel cover is limited after the sewage is separated from the sewage outlet, the sewage continuously moves upwards after being separated from the sewage outlet and then impacts the barrel cover or a baffle between the barrel cover and the sewage inlet pipe to realize gas-liquid separation, if the isolation gap is too small, the impacted sewage splashes around, part of sewage and small-particle sewage splashes onto the sea handkerchief after impact, the service life of the sea handkerchief is shortened, even part of liquid drops penetrate through the sea handkerchief and enter the vacuum motor, the vacuum motor is damaged, and the service life of the surface cleaning device is shortened. Second, the isolation clearance undersize between filth export and the bung, large granule solid filth are deviate from the back by the filth export and are blocked and can't move to the bilge well bottom between the isolation clearance, and large granule solid particle matter is piled up in the isolation clearance and can't fall to the bilge well bottom, and the route that outside air flowed in to the bilge well is blockked up to the part or even whole, reduces vacuum motor's soil pick-up ability. Thirdly, the installation space of the baffle, the liquid full detection part and the filtering device is less influenced by the isolation clearance, and the requirements of sewage bucket functional diversity such as sewage bucket sewage classified storage and liquid full automatic alarm cannot be met.
The pipe diameter of the sewage inlet pipe and the height of the sewage inlet pipe jointly determine the amount of sewage released into the sewage bucket from the sewage inlet pipe in a certain working efficiency unit time of the vacuum motor, the more the amount of the sewage released into the sewage bucket from the sewage inlet pipe in the certain working efficiency unit time of the vacuum motor is, the more smooth an airflow channel from the outside of the sewage suction port to the sewage bucket is, the larger the suction force generated by the vacuum motor at the sewage suction port is, and the better the cleaning force of the surface to be cleaned by the surface cleaning device is.
In summary, the slop pail matched with the vacuum motor needs to be selected according to the power of the vacuum motor, so that the ratio of the working power of the vacuum motor to the pipe diameter and height of the sewage inlet pipe in the slop pail can be always kept in a limited range in the working process of the surface cleaning device. The suction force generated along with the pressure change in the sewage bucket can meet the cleaning requirement of a user on the surface to be cleaned when the user drives the surface cleaning device to clean, meanwhile, enough power is provided for the sewage to climb in the sewage suction channel, the sewage can be orderly separated from the sewage outlet through the sewage suction channel, solid-liquid separation is completed in the sewage bucket through the filtering device arranged on the bucket cover, and classified storage of the sewage is completed, so that the working efficiency of the surface cleaning device is ensured.

It should be noted that the surface cleaning apparatus of the present disclosure may be a self-propelled surface cleaning robot, or may be a hand-held surface cleaning apparatus. The self-walking surface cleaning robot comprises the structure and walking wheels for supporting and driving the surface cleaning device to walk. The surface cleaning apparatus of the present disclosure is exemplified below with reference to the accompanying drawings in conjunction with a hand-held surface cleaning apparatus.
The first embodiment is as follows:
as shown in fig. 1-3, the solid line arrows indicate the movement direction of the dirt, and the dotted line arrows indicate the flow direction of the gas after the dirt hits the baffle plate and is separated from the gas. A surface cleaning apparatus with good dirt pick-up is shown, comprising a body with a vacuum motor 11 and a body 1 with a cleaning element 10, which body and body 1 are pivotally connected. The machine body 1 is provided with a dirt suction port 12 for sucking dirt on the cleaning piece 10 and the surface to be cleaned, the cleaning piece 10 can be in various forms such as a cleaning roller, a cleaning brush, a cleaning turntable and the like, and the cleaning piece 10 rotates to wipe the surface to be cleaned. The machine body comprises a vacuum motor 11 for providing suction force, a sewage suction channel 13 which is communicated with a sewage suction port 12 on the machine body 1 and is used for sucking sewage, and a sewage bucket 3 of which one end is communicated with the vacuum motor 11 and the other end is communicated with the sewage suction channel 13 and is used for collecting sewage. The sewage bucket 3 comprises a bucket cover 4 and a bucket body 5, the bottom of the bucket body 5 is provided with a sewage inlet pipe 6 which extends upwards, the sewage inlet pipe 6 comprises a sewage inlet 61 which is positioned at the bottom of the sewage inlet pipe 6 and a sewage outlet which is positioned at the top of the sewage inlet pipe 6, and the sewage inlet pipe 6 forms a part of the sewage suction channel 13. The body further comprises a clean water bucket 2 for supplying cleaning liquid to the cleaning elements 10 and a liquid supply pipe for supplying the cleaning liquid, wherein the liquid supply pipe is connected with the body 1 and supplies the cleaning liquid to the cleaning elements 10 to wet the cleaning elements 10.
When the surface cleaning device is in operation, the clean water bucket 2 supplies cleaning liquid to the cleaning element 10 via the liquid supply duct, and the cleaning element 10 is rotated to wipe the surface to be cleaned. The vacuum motor 11 works to continuously vacuumize the sewage bucket 3 communicated with the vacuum motor 11, and the other end of the sewage bucket 3 is communicated with the sewage suction channel 13. Therefore, when the vacuum motor 11 is operated, the air pressure in the sewage bucket 3 is continuously reduced under the suction of the vacuum motor 11, and the air outside the sewage suction port 12 communicated with the sewage bucket 3 flows from the ground with high air pressure to the place with low air pressure, so that negative pressure and air flow are formed in the sewage bucket 3, the sewage suction channel 13 and the sewage suction port 12. The dirty liquid and the dirt generated after the cleaning piece 10 wipes the surface to be cleaned enter the dirt suction channel 13 from the dirt suction port 12 under the action of the vacuum motor 11, move towards the sewage bucket 3 along the dirt suction channel 13 under the entrainment of the air flow, and are finally released by the dirt outlet 62 at the top of the dirt inlet pipe 6 and stored in the sewage bucket 3.
Different working modes, such as a common cleaning mode, a deep cleaning mode and the like, can be selected by users according to different dirt degrees of the surface to be cleaned during the working process of the surface cleaning device so as to realize thorough cleaning of the surface with different dirt degrees. It is generally believed that the higher the power of the vacuum motor 11, the more negative pressure and air flow that can be generated, and the better the cleaning force on the surface to be cleaned, all other things being equal. However, the parameters of the slop pail 3 connected with the vacuum motor 11 directly affect the suction and storage of dirt, and if the parameters of the vacuum motor 11 and the slop pail 3 are not matched, even if the working power of the vacuum motor 11 is increased, the ideal cleaning effect cannot be achieved, and even the opposite effect that the higher the working power of the vacuum motor 11 is, the worse the cleaning effect of the surface cleaning device is may occur. The utility model provides a matching relation of vacuum motor 11 power and the parameter of dirty tub 6 of advancing in 3, the specific value that makes vacuum motor 11's operating power and the pipe diameter d of dirty tub 6 of advancing and vacuum motor 11's operating power and the high H's of dirty tub 6 ratio of advancing satisfy appointed specific value simultaneously and give full play to vacuum motor 11's soil pick-up effect, promote surface cleaning device's soil pick-up, clean ability.
The vacuum motor 11 with the rated power of 100W-300W is used, the sewage bucket 3 with the sewage inlet pipe 6 is used in a matched mode, an isolation gap h exists between the sewage outlet 62 of the sewage inlet pipe and the bucket cover 4, and therefore the surface cleaning device can meet the condition that the ratio of the working power of the vacuum motor 11 to the pipe diameter d of the sewage inlet pipe 6 is 5:1(W/mm) -10:1(W/mm), and the ratio of the working power of the vacuum motor 11 to the height H of the sewage inlet pipe 6 is 1:1(W/mm) -2:1 (W/mm).
Preferably, a vacuum motor 11 with rated power of 100W-200W is selected, and a sewage bucket 3 with a sewage inlet pipe 6 with the pipe diameter d of 10mm-40mm and the height H of the sewage inlet pipe 6 of 50mm-200mm needs to be matched; the vacuum motor 11 with the rated power of 200W-300W is selected to be matched with the sewage bucket 3 with the sewage inlet pipe 6 with the pipe diameter d of 20mm-60mm and the height H of the sewage inlet pipe 6 of 100mm-300 mm. The ratio of the working power of the vacuum motor 11 to the pipe diameter and the height of the sewage inlet pipe 6 is in the range of the ratio no matter what gear is used when the surface cleaning device works.
A vacuum motor 11 with rated power of 100W-200W is used, a sewage inlet pipe 6 with matching pipe diameter d of 10mm-40mm and height H of 50mm-200mm is used, for example, the sewage inlet pipe 6 with matching pipe diameter of 23mm and height of 100mm is used, the vacuum motor 11 generates negative pressure in the sewage barrel 3, air outside a sewage suction port 12 flows to a sewage suction channel 13 to generate suction airflow, and dirt enters the sewage barrel 3 through the sewage inlet pipe 6 under the entrainment of the airflow. The ratio of the operating power of the vacuum motor 11 to the parameters of the sewage inlet pipe 6 is in a limited range, so that the sewage suction capacity of the surface cleaning device adopting the vacuum motor 11 with the rated power of 100W-200W is not weaker than that of the surface cleaning device with the operating power of more than 200W under the same condition. Meanwhile, because the power of the vacuum motor 11 is low, the electric consumption is small, compared with the vacuum motor 11 with the working power of more than 200W, the electric consumption of the surface cleaning device in unit time is low, and the requirement of a user for realizing the whole-house cleaning can be met by selecting a battery pack with smaller capacity under the condition of certain endurance time. The quality of the surface cleaning device vacuum motor 11 and the battery pack is lighter and the overall quality and the volume of the surface cleaning device are reduced for a short time on the premise that the cleaning power and the endurance of the surface cleaning device are not reduced, and the surface cleaning device is light and easy to store for user operation.
A vacuum motor 11 with rated power of 200W-300W is used to match a sewage inlet pipe 6 with the pipe diameter d of 20mm-60mm and the height H of 100mm-300 mm. For example, the matched sewage inlet pipe 6 with the pipe diameter of 30mm and the height of 150mm fully meets the air flow flowing speed in the sewage suction channel 13 when the vacuum motor 11 works, so that the sewage in the sewage suction channel 13 can pass through the sewage inlet pipe 6 without obstruction and is not retained in the sewage inlet pipe 6 any more, the smoothness of the sewage suction channel 13 is ensured, and the sewage collection amount of the surface cleaning device in unit time is increased.
The pipe diameter d of the sewage inlet pipe 6 and the height H of the sewage inlet pipe 6 jointly determine the amount of sewage released from the sewage inlet pipe 6 into the sewage bucket 3 within a certain unit time of the working efficiency of the vacuum motor 11, the larger the amount of sewage released from the sewage inlet pipe 6 into the sewage bucket 3 within a certain unit time of the working efficiency of the vacuum motor 11, the smoother the airflow channel from the outside of the sewage suction port 12 to the sewage bucket 3, the larger the suction force generated by the vacuum motor 11 at the sewage suction port 12, the better the cleaning force of the surface cleaning device on the surface to be cleaned. Therefore, the sewage bucket 3 matched with the vacuum motor 11 is selected to ensure that the ratio of the working power of the vacuum motor 11 to the pipe diameter d of the sewage inlet pipe 6 and the ratio of the working power of the vacuum motor 11 to the height H of the sewage inlet pipe 6 can meet the specified range no matter what cleaning mode the surface cleaning device works in, the better sewage suction effect can be realized by keeping the vacuum motor 11 at relatively lower power while the good sewage suction effect of the vacuum motor 11 is ensured, and the noise of the surface cleaning device is lower.
Further, the sewage bucket 3 is provided with the highest water level, and the equivalent sewage volume of the highest water level of the sewage bucket 3 is not more than 1/2 of the volume of the sewage bucket 3; preferably, the effective volume of the slop pail 3 is 300ml-900ml of slop pail 3. The surface cleaning device is usually internally provided with a highest water level line and a liquid full alarm device for controlling the dirt storage amount not to exceed the highest water level line, and the liquid full alarm device can be a float valve, a photoelectric alarm structure, an electrode structure and the like. The equivalent sewage volume of the highest water level line is not more than 1/2 of the volume of the sewage bucket 3, firstly, a certain installation space is provided for the liquid full alarm device, secondly, the highest water level line of the sewage bucket 3 is lower than the sewage outlet 62 of the sewage inlet pipe 6, the sewage entering the sewage bucket 3 is prevented from falling out of the secondary pollution surface to be cleaned again through the sewage inlet pipe 6, the use feeling of uncleanness and leakage of the surface cleaning device is caused to users, meanwhile, a certain falling space is provided for the sewage separated from the sewage outlet 62, gas-liquid separation and solid-liquid separation are realized in the falling process, and the original sewage in the sewage bucket 3 is splashed when the falling space is insufficient after the sewage moving along with the airflow is separated from the sewage outlet 62 and is directly stored at the bottom of the sewage bucket 3; and finally, a filtering device 7 is arranged on the inner barrel cover 4 of the sewage barrel 3, and the filtering device 7 is provided with a space for installing and storing solid sewage, so that the sewage subjected to solid-liquid separation by the filtering device 7 is not subjected to secondary mixing.
Preferably, the position of the dirt outlet 62 of the dirt inlet pipe 6 is above 30mm above the highest water level line of the sewage barrel 3, so that the dirt is separated from the dirt outlet 62 and then collides with the baffle plate to separate gas from other dirt, the solid-liquid separation is realized by the filtering device 7 in the falling process of the dirt moving towards the bottom of the sewage barrel 3, the speed is increased continuously under the action of gravity to gather with the dirt originally stored in the sewage barrel 3, and part of the dirt is splashed, so that the dirt outlet 62 is located above 30mm above the highest water level line of the sewage barrel 3, the dirt outlet 62 is fully far away from the highest water level line to provide a space for splashing the dirt stored at the bottom of the sewage barrel 3, namely, the dirt is splashed in the sewage barrel and cannot be splashed to the dirt outlet 62, secondary pollution caused by the dirt splashed out of the sewage barrel 3 by the dirt outlet 62 is avoided, and meanwhile, enough installation space is reserved for the liquid level liquid full detection device and the filtering device 7 to avoid gas-liquid separation of the dirt, The solid-liquid separation is insufficient, and the liquid full detection false alarm is frequent.
Selecting a vacuum motor 11 with rated power of 100W-300W, keeping the working power of the vacuum motor 11 and the height of the sewage inlet pipe 6 unchanged, enabling the ratio of the working power of the vacuum motor 11 to the height H of the sewage inlet pipe 6 to be in accordance with the conditions between 1:1(W/mm) -2:1(W/mm), and selecting a sewage bucket 3 with a smaller pipe diameter d of the sewage inlet pipe 6 to enable the ratio of the working power of the vacuum motor 11 to the pipe diameter d of the sewage inlet pipe 6 to be larger than 10:1(W/mm), the passage for the outside air to enter the slop pail 3 is narrow, and the negative pressure condition can be better formed in the slop pail 3 because the air pressure in the slop pail 3 drops at a high speed. The suction force of the vacuum motor 11 through the soil suction port 12 by the negative pressure in the soil tub 3 is large but the throughput of soil per unit time is limited due to the small pipe diameter d of the soil inlet pipe 6. The speed that the filth is deviate from by filth export 62 is less than the speed that the filth gets into soil pick-up passageway 13 by soil pick-up mouth 12 and leads to surface cleaning device to be blockked up by the filth gradually at the in-process soil pick-up passageway 13 of work, and after surface cleaning device worked a period, the filth that gets into soil pick-up passageway 13 by soil pick-up mouth 12 took place to block up in soil pick-up passageway 13, and the diameter of solid filth is greater than the pipe diameter of sewage inlet pipe 6 and directly blocks up soil pick-up passageway 13 even when waiting to clean the surface and having great solid filth. The speed that outside air flows to the soil pick-up passageway slows down gradually at the in-process that soil pick-up passageway 13 is blockked up, the suction force of soil pick-up mouth 12 department reduces gradually, the soil dirt suction capacity of surface to be cleaned of surface cleaning device weakens gradually to the soil pick-up passageway 13 is blockked up by the filth completely, slop pail 3 can't form the route with the outside air, the filth on the surface to be cleaned and on cleaning member 10 can't be cleared up under the suction force effect that vacuum motor 11 produced, the filth that keeps on cleaning member 10 pollutes cleaning member 10, it is dirty more to lead to the cleaning member 10 to treat the cleaning surface's cleanness more, surface cleaning device inefficacy. Meanwhile, the dirt suction channel is not easy to clean and the user can not independently clean the dirt blocked in the dirt suction port 12 and the dirt suction channel 13, so that the problems of early scrapping and after-sale of the surface cleaning device are increased. And the higher the ratio of the working power of the vacuum motor 11 to the pipe diameter d of the sewage inlet pipe 6 under the same conditions, the faster the failure process of the surface cleaning device occurs.
Selecting a vacuum motor 11 with rated power of 100W-300W, keeping the working power of the vacuum motor 11 and the height H of the sewage inlet pipe 6 unchanged, ensuring that the ratio of the working power of the vacuum motor 11 to the height H of the sewage inlet pipe 6 is between 1:1(W/mm) -2:1(W/mm) to meet the conditions, and selecting a sewage bucket 3 with a larger pipe diameter d of the sewage inlet pipe 6 to ensure that the ratio of the working power of the vacuum motor 11 to the pipe diameter d of the sewage inlet pipe 6 is less than 5:1(W/mm) the sewage bucket 3 has a larger path communicated with the outside air through the sewage inlet pipe 6, the air outside the sewage suction channel 13 can be quickly filled with the air pumped by the vacuum motor 11 in the process that the vacuum motor 11 vacuumizes the sewage bucket 3, so that the air pressure in the sewage bucket 3 with the large pipe diameter of the sewage inlet pipe 6 is slower than that in the sewage bucket 3 with the small pipe diameter of the sewage inlet pipe 6 in the process that the vacuum motor 11 vacuumizes the sewage bucket 3 by adopting the same working power, sufficient negative pressure cannot be formed in the sewage bucket 3, the air flow rate of the outside air flowing to the sewage suction channel 13 is slower, the suction force of the vacuum motor 11 on the surface to be cleaned and the sewage on the cleaning piece 10 is weakened, the sewage cannot be driven to climb to the sewage outlet 62 at the top of the sewage inlet pipe 6 along the sewage inlet pipe 6, and is collected into the sewage bucket 3 after being separated from the sewage inlet pipe 6. The surface cleaning apparatus can greatly reduce the speed of collecting dirt and the amount of collecting dirt on the surface to be cleaned during the same operation time even if the dirt can be finally collected in the tub 3. To the air current that the great filth of volume, quality can not be produced by the vacuum motor and carry the parcel and get into the dirt absorbing channel in, some filths can't be handled and still stay in waiting to clean the surface, can't satisfy user's clean demand. On the other hand, for small and light dirt, the dirt collection amount per unit time of the surface cleaning device is reduced due to the reduction of the suction force, and when a user drives the surface cleaning device at a normal walking speed to clean the surface to be cleaned, the cleaning of the designated surface to be cleaned cannot be completed within a limited residence time, so that the cleaning effect is poor. The need to increase the operating power of the vacuum motor 11 to increase the cleaning capacity of the surface cleaning apparatus increases the noise generated by the operation of the vacuum motor 11, which can be annoying to the user and can also result in wasted power.
Selecting a vacuum motor 11 with rated power of 100W-300W, keeping the working power of the vacuum motor 11 and the pipe diameter d of the sewage inlet pipe 6 unchanged, ensuring that the ratio of the working power of the vacuum motor 11 to the pipe diameter d of the sewage inlet pipe 6 is between 5:1(W/mm) -10:1(W/mm) to meet the conditions, and selecting a sewage bucket 3 with a lower height H of the sewage inlet pipe 6 to ensure that the ratio of the working power of the vacuum motor 11 to the height H of the sewage inlet pipe 6 is more than 2:1 (W/mm). For example, the operating power of the vacuum motor 11 is 100W, the pipe diameter d of the sewage inlet pipe 6 is 21mm, and the height is 45 mm. The sewage outlet 62 is positioned above the highest water level line of the sewage bucket 3 by more than 30mm, the distance between the highest water level position of the sewage bucket 3 and the bottom of the sewage bucket 3 is less than 15mm, the effective sewage capacity of the sewage bucket 3 is small, a user uses the surface cleaning device to clean the indoor fashionable unfinished whole-house cleaning sewage bucket 3 to meet the full-liquid alarm condition firstly, and the cleaning work is forced to be interrupted. The user experience is poor even if he needs to pour the slop pail 3 several times during one cleaning process.
Selecting a vacuum motor 11 with rated power of 100W-300W, keeping the working power of the vacuum motor 11 and the pipe diameter d of the sewage inlet pipe 6 unchanged, ensuring that the ratio of the working power of the vacuum motor 11 to the pipe diameter d of the sewage inlet pipe 6 is between 5:1(W/mm) -10:1(W/mm) to meet the conditions, and selecting a sewage bucket 3 with a higher height of the sewage inlet pipe 6 to ensure that the ratio of the working power of the vacuum motor 11 to the height H of the sewage inlet pipe 6 is less than 1:1 (W/mm). For example, the working power of the vacuum motor 11 is 100W, the pipe diameter d of the sewage inlet pipe 6 is 21, and the height h is 120 mm. Higher dirty intake pipe 6 makes the filth overcome gravity by waiting to clean the surface and need consume more energy to the in-process of slop pail 3 motion, the soil climbing time in soil pick-up passageway 13 is longer under the condition that vacuum motor 11 operating power does not promote, it takes longer time or needs great vacuum motor 11 operating power to make the filth deviate from in the intake pipe 6 and is collected to collect the same amount of filth, the filth keeps somewhere for a long time in intake pipe 6, it is inside the slop pail 3 to hinder the air current by soil pick-up mouth 12 outside, vacuum motor 11's soil pick-up ability reduces, surface cleaning device's cleaning power is not enough. On the other hand, the relatively high sewage inlet pipe 6 enables the isolation gap h between the sewage outlet 62 and the barrel cover 4 to be small, sewage is separated from the sewage outlet 62 and then continuously moves upwards to impact the barrel cover 4 and splashes around, part of sewage and small-particle sewage splashes to the HEPA after being impacted, the service life of the HEPA is shortened, and even part of liquid drops pass through the HEPA to enter the vacuum motor 11 to damage the vacuum motor 11.
Further, an isolation gap h exists between the dirt outlet 62 and the barrel cover 4, the dirt still needs to continuously move upwards for a certain distance after being separated from the dirt outlet 62, the isolation gap h provides a space for the dirt to continuously move upwards after being separated from the dirt inlet 61, if the dirt is too small in the isolation gap h, the dirt is directly arranged on the barrel cover after being separated from the dirt outlet 62 or directly vertically falls into the dirt inlet pipe 6 after being impacted by a baffle on the barrel cover, the dirt cannot be collected and secondary pollution can be caused; on the other hand, the dirt has a high movement speed after being separated from the dirt outlet 62, the dirt splashes around after impacting the barrel cover or the baffle at a high speed, the splashing range of the dirt is larger than that after impacting at a relatively low speed, part of the dirt is keyed into the filtering piece 9 of the barrel cover, the service life of the filtering piece 9 is easily influenced, and even part of the dirt directly passes through the filtering piece 9 at a high movement speed to enter the vacuum motor 11, and the service life of the vacuum motor 11 is influenced. Larger solid dirt particles may exist on the surface to be cleaned, and the isolation gap h provides a space for the solid dirt to fall to the bottom of the sewage bucket 3 after falling out from the dirt outlet 62, so that the larger solid dirt particles are prevented from being stuck at the dirt outlet 62 to influence the circulation of outside air into the sewage bucket, the suction force of the vacuum motor is weakened, and even the surface cleaning device fails. On the other hand, the separation gap h provides a space for installing components such as the baffle 8, the filter device 7, and the liquid level detection device in the slop water tank 3.
The working power of the vacuum motor 11, the pipe diameter of the sewage inlet pipe 6 and the height of the sewage inlet pipe 6 jointly determine the sewage suction effect of the vacuum motor 11, namely the amount of sewage released from the sewage inlet pipe 6 to the sewage bucket 3 in a certain unit time. The more the dirt is released into the sewage bucket 3 from the sewage inlet pipe 6 in a unit time by the working power of the vacuum motor 11, the smoother the airflow channel from the outside of the sewage suction port 12 to the sewage bucket 3, the larger the suction force generated by the vacuum motor 11 at the sewage suction port 12, and the better the cleaning force of the surface cleaning device on the surface to be cleaned.
In summary, the slop pail 3 matched with the vacuum motor 11 needs to be selected according to the power of the vacuum motor 11 so that the ratio of the working power of the vacuum motor 11 to the pipe diameter and height of the sewage inlet pipe 6 in the slop pail 3 is always kept within a limited range during the operation of the surface cleaning apparatus.
