Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "inner", "outer", "left", "right" and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Referring to fig. 1, 2 and 3, a cleaning apparatus 10 according to an embodiment of the present invention includes a storage container 20, and the cleaning apparatus 10 may be used for cleaning a floor. The storage container 20 may be a clean water tank 21 for storing clean water, and may also be a sewage tank 22 for storing sewage. Clean water from the clean water tank 21 is supplied to the mopping member of the cleaning device 10 for cleaning the floor, and sewage formed by the mopping member during cleaning the floor is recycled to the sewage tank 22. The cleaning apparatus 10 may be a cleaning robot or a hand-held mopping machine or the like. The storage container 20 includes a container body 100 and a sensing assembly 200.

In some embodiments, the storage container 20 includes a base plate 110, a cover plate 120, a side tube 130, and a partition 140. The side tube 130 is a hollow column structure, the bottom plate 110 is connected to the lower end of the side tube 130, and the cover plate 120 is connected to the upper end of the side tube 130. The bottom plate 110, the cover plate 120 and the side tube 130 jointly enclose a containing cavity 150, and liquid is stored in the containing cavity 150. The cover plate 120 may be rotatably coupled to the side tube 130, and the cover plate 120 may open the receiving chamber 150 when the cover plate 120 is rotated away from the side tube 130. In operation of the cleaning device 10, the storage container 20 is arranged upright such that the cover plate 120 is positioned above the base plate 110.

In the case that the storage container 20 is vertically disposed and a certain amount of liquid is stored in the accommodating chamber 150, the position of the liquid level of the liquid is a certain height h from the bottom plate 110, and the height value can be defined as a liquid level value h of the position of the liquid level. Therefore, when the accommodating chamber 150 is empty without any liquid, the liquid level is at a minimum and zero level, i.e. the liquid level value is at a minimum and zero level. When the accommodation chamber 150 is saturated with liquid, the liquid level is at a maximum, i.e. a maximum level value. Obviously, the bottom plate 110 will be always covered by the liquid as long as the liquid is contained in the containing cavity 150; in case the receiving chamber 150 is in a saturated state, the liquid level of the liquid will reach the position of the cover plate 120, so that the liquid can contact the cover plate 120. When the accommodating chamber 150 is in an unsaturated state, a certain distance is kept between the liquid level of the liquid and the cover plate 120, so that the liquid level cannot reach the position of the cover plate 120, and the liquid cannot contact the cover plate 120.

Referring to fig. 3, 4 and 5, in some embodiments, the partition plate 140 is fixed in the accommodating cavity 150, the partition plate 140 may partition the accommodating cavity 150 into two relatively independent cavities, the two cavities are respectively denoted as a first cavity 151 and a second cavity 152, and a volume of the first cavity 151 may be larger than a volume of the second cavity 152. A gap exists between the lower end of the partition 140 and the bottom plate 110, and the gap is denoted as a communication gap 153, and the communication gap 153 communicates the first cavity 151 and the second cavity 152. The first cavity 151 is always in communication with the outside, and the second cavity 152 is hermetically disposed with respect to the outside. When liquid is injected into the first cavity 151, the liquid in the first cavity 151 flows into the second cavity 152 through the communicating gap 153, the liquid entering the second cavity 152 occupies a part of the accommodating space of the gas, when the liquid level in the second cavity 152 rises, the liquid level in the second cavity 152 also rises at the same time, and the gas pressure in the second cavity 152 increases because the liquid in the second cavity 152 is in a sealing state without communicating with the outside, and the gas pressure in the second cavity 152 is equal to the sum of the atmospheric pressure and the liquid pressure in the first cavity 151. In other embodiments, the lower end of the partition plate 140 may be directly fixed to the bottom plate 110 so as to eliminate a gap between the lower end of the partition plate 140 and the bottom plate 110, and at this time, a communication hole for communicating the first chamber 151 and the second chamber 152 may be opened inside the bottom plate 110.

In some embodiments, the detection assembly 200 includes a barometer 210, a liquid empty sensor 220 and a liquid full sensor 230, the barometer 210 may be disposed near the upper end of the side tube 130 in view of the connection of the upper end of the side tube 130 and the cover plate 120, and the barometer 210 obtains the liquid level value of the liquid in the first cavity 151 by measuring the gas pressure in the second cavity 152. For example, let the liquid pressure in the first chamber 151 be P ₁ The gas pressure in the second chamber 152 is denoted as P ₂ And the local atmospheric pressure is noted as P ₀ The density of the liquid is denoted ρ and the level value h, in view of P ₂ ＝P ₀ +P ₁ ＝P ₀ + ρ g h, so h is calculated as: h = P ₂ -P ₀ And/[ rho ] g. Thus, P ₂ And h form a one-to-one correspondence relationship, and as long as the barometer 210 can measure the air pressure in the second cavity 152, the level value h can be obtained, so that the level value h corresponding to the liquid level at any position can be effectively obtained through the barometer 210. This liquid level value h can present through the display screen on cleaning device 10, can also observe liquid level value h through interactive ends such as smart mobile phone for barometer 210 effectively exerts the detection and the acquisition function to liquid level value h, guarantees that the user accurately judges the remaining liquid volume in holding chamber 150 through liquid level value h, so that make reasonable arrangement to actual work. In the case where the storage container 20 is made of a non-transparent material and is hidden inside the cleaning apparatus 10, the user can accurately determine the actually remaining liquid amount without taking the storage container 20 out of the cleaning apparatus 10, thereby improving the convenience of using the storage container 20 and the cleaning apparatus 10. The damage possibly caused by the bump during the process of taking out the storage container 20 by the user can be effectively avoided, so that the use safety of the cleaning device 10 is improved.

Referring to fig. 2, 3 and 4, in some embodiments, the lower end of the side tube 130 is connected to the bottom plate 110, the liquid level sensor 220 may be disposed near the lower end of the side tube 130, and the liquid level sensor 220 is used for acquiring a liquid level value of the liquid when the first cavity 151 is in an empty state, so that the liquid level sensor 220 monitors and prompts the empty state of the first cavity 151 in time, and obviously, the liquid level value acquired by the liquid level sensor 220 will be zero. At this time, the second chamber 152 is communicated with the external atmosphere through the first chamber 151, i.e. the gas pressure in the second chamber 152 is equal to the local atmospheric pressure. Since the local atmospheric pressure is related to the altitude and the temperature, and the atmospheric pressure is different in different space-time ranges, the local atmospheric pressure needs to be measured before each measurement, so as to accurately calculate the level value h. Therefore, before the level value is measured by the barometer 210, the empty state of the first cavity 151 can be known by the indication of the liquid-air sensor 220, and the measurement accuracy of the local atmospheric pressure is ensured by using the gas pressure measured by the barometer 210 as the local atmospheric pressure, thereby improving the measurement accuracy of the level value h.

Through setting up liquid empty sensor 220, can rectify local atmospheric pressure according to barometer 210, and then play the effect of "zero setting" to detection element 200 to establish the basis for improving the measurement accuracy of level value h, ensure that the user accurately judges the remaining liquid volume in holding chamber 150, improve the convenience that storage container 20 used. When the accommodating cavity 150 is in an empty state and the storage container 20 is used as the clean water tank 21, the work of the cleaning device 10 can be stopped in time, the cleaning device 10 is prevented from working under the condition that no clean water is provided, on one hand, the cleaning head of the cleaning device 10 can be prevented from being damaged, and therefore the use safety of the cleaning device 10 is improved; on the other hand, the cleaning head is prevented from doing useless work. Meanwhile, under the condition that the liquid level cannot be monitored due to damage of the barometer 210, the liquid-air sensor 220 can effectively transmit the information that the accommodating cavity 150 is in the empty state to the user, so that the user can timely stop the cleaning device 10 when the accommodating cavity 150 is in the empty state, and the use safety and convenience of the cleaning device 10 are further improved.

In some embodiments, a liquid full sensor 230 may be disposed near the upper end of the side tube 130, and the liquid full sensor 230 is used to obtain a liquid level value when the first cavity 151 is in a saturated state. So that the liquid-air sensor 220 monitors and prompts the saturation state of the first cavity 151 in time. When the storage container 20 is used as a cleaning tank and the liquid in the accommodating chamber 150 is clear water and cleaning liquidWhen the mixed liquid is formed, the density of the mixed liquid needs to be obtained, and the liquid level value h cannot be directly calculated according to the density of water. Therefore, when the level sensor 230 indicates that the receiving cavity 150 is in a saturated state, the level value h will be equal to the height of the whole receiving cavity 150, which can be according to the formula h = P ₂ -P ₀ The density of the mixed liquid is accurately calculated by the rhog, so that the measurement precision of the subsequent liquid level value h is improved, the user is ensured to accurately judge the residual liquid amount in the accommodating cavity 150, and the use convenience of the storage container 20 and the whole cleaning device 10 is improved. Meanwhile, under the condition that the liquid level cannot be monitored due to damage of the barometer 210, the liquid level sensor 230 can effectively transmit information that the accommodating cavity 150 is in a saturated state to a user, so that the user timely stops injecting liquid into the storage device when the accommodating cavity 150 is in the saturated state, the liquid is prevented from overflowing to damage the cleaning device 10, and the use safety and convenience of the cleaning device 10 can be improved.

If the detecting element 200 can only detect the level values of the liquid when the accommodating chamber 150 is in the saturated state and in the empty state, that is, only the highest position and the lowest position of the liquid level can be detected, so that any position between the highest position and the lowest position of the liquid level cannot be detected timely, and the user cannot accurately grasp the amount of the liquid remaining in the accommodating chamber 150 timely. Thus, at least the following disadvantages will exist: for example, in order to improve the cleaning effect, when the storage container 20 is used as the clean water tank 21, it is necessary to appropriately heat the liquid in the storage container 20. If the liquid in the storage container 20 is too much and the range of the ground to be cleaned is narrow, after the ground cleaning is completed, the liquid with temperature which is not consumed exists in the storage container 20, and the cleaning device 10 is in a shutdown state at this moment, and the residual liquid in the storage container 20 is converted into the liquid with normal temperature by dissipating heat due to being unable to be used in time, so that energy waste is inevitably caused. Of course, when the ground range is wide, the temperature of the liquid in the storage container 20 is insufficient. For another example, the liquid in the accommodating cavity 150 needs to be electrolyzed to have the function of sterilization, and since the user cannot accurately grasp the amount of liquid remaining in the accommodating cavity 150, and thus cannot accurately grasp the electrolysis time of the liquid, the concentration of the electrolyzed liquid cannot be accurately determined, and the concentration of the electrolyzed liquid is too low or too high. In fact, liquids with too high a concentration have a strong irritating odor, which causes discomfort to the human body and thus affects the safety of the use of the cleaning device 10.

For the storage container 20 in the above embodiment, the level value h can be measured by the detection component 200, so that the user can accurately determine the amount of liquid remaining in the accommodating cavity 150, and when the liquid needs to be heated, a proper amount of liquid can be heated according to the actual floor cleaning range, thereby avoiding the phenomenon of energy waste caused by insufficient liquid or excessive liquid. When the liquid needs to be electrolyzed, the electrolysis time can be accurately increased according to the residual liquid amount, so that the concentration of the electrolyzed liquid is moderate, and the convenience and the safety of the storage container 20 and the whole cleaning device 10 in use are improved.

Referring to fig. 6 and 7, in some embodiments, the sensing assembly 200 may include a distance sensor 240 or a pressure sensor 250, the receiving body may not include the diaphragm 140, and the distance sensor 240 or the pressure sensor 250 is used instead of the pressure gauge to sense the level value h. The distance sensor 240 may be mounted on the upper end of the side tube 130 or the cover plate 120, and when the liquid in the accommodating chamber 150 is in an unsaturated state, the distance sensor 240 cannot be soaked by the liquid, so that the distance between the distance sensor 240 and the liquid level is always kept. When the liquid in the accommodating chamber 150 is in a saturated state, the distance sensor 240 may just contact the liquid, i.e. the distance between the distance sensor 240 and the liquid surface is just zero. The distance sensor 240 may obtain the level value by measuring a distance between itself and the liquid level, specifically, the height of the accommodating cavity 150 may be denoted as a, a distance between the distance sensor 240 and the liquid level is denoted as B, and the level value h = a-B.

For example, referring to fig. 6, the distance sensor 240 may be an infrared sensor 241, the infrared sensor 241 emits infrared rays to reach the liquid level, the infrared rays are reflected by the liquid level and then received by the infrared sensor, and the infrared sensor 241 may calculate the value B according to the time difference between the emission and the reception of the infrared rays, thereby calculating the level value h. For another example, referring to fig. 7, the distance sensor 240 may be an ultrasonic sensor 242, the ultrasonic sensor 242 transmits an ultrasonic wave to reach the liquid level, the ultrasonic wave is reflected by the liquid level and then received by the ultrasonic sensor, the ultrasonic sensor 242 may calculate the value of B according to the time difference between the transmission and the reception of the ultrasonic wave, and may also calculate the level value h.

Referring to fig. 8, the pressure sensor 250 may be disposed on the bottom plate 110 and outside the accommodating chamber 150, for example, the pressure sensor 250 may be mounted on the lower surface of the bottom plate 110. When the storage container 20 is installed in the cleaning apparatus 10, the container body 100 containing the liquid is ballasted on the pressure sensor 250, and the pressure sensor 250 is used to acquire a level value by measuring the gravity of the liquid. Specifically, the sum of the weight of the container body 100 and the liquid can be determined from the pressure value measured by the pressure sensor 250, and since the weight of the container body 100 is known, the weight of the liquid can be obtained, and the cross section of the container body 100 is known, and finally the level value h can be further obtained from the relationship between the weight and the volume.

In the case where the storage container 20 is used as the sewage tank 22, when it is judged by the sensing member 200 that the sewage of the sewage tank 22 is about to be filled, the sewage can be discharged in time.

The utility model also provides a basic station, this basic station and the supporting use of cleaning device 10, the basic station can charge for cleaning device 10. The base station may also comprise the above-mentioned storage container 20, the storage container 20 being adapted to replenish the cleaning liquid in the clean water tank 21 of the cleaning device 10 when the storage container 20 is used as the clean water tank 21; the storage container 20 may also provide cleaning fluid to the sink of the base station itself, which will clean the mop when it is located on the cleaning device 10. When the storage container 20 is used as the sewage tank 22, the storage container 20 can recover the sewage in the sewage tank 22 of the cleaning apparatus 10; after the mopping member on the cleaning device 10 is cleaned in the cleaning tank, the storage container 20 can directly recover the sewage in the cleaning tank.

All possible combinations of the technical features of the above embodiments may not be described for the sake of brevity, but should be considered as within the scope of the present disclosure as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the concept of the present invention, several variations and modifications can be made, which all fall within the scope of the present invention.
