Description

[Technical field]

[0001] The present invention relates to the field of vacuum cleaners, and more particularly to a liquid storage container and an intelligent cleaning device having the same. [Background technology]

[0002] With the development of technology, various automatic vacuum cleaners have appeared, such as automatic sweeping robots and automatic mopping robots. Automatic vacuum cleaners can perform cleaning tasks automatically, which brings convenience to users. For example, automatic cleaning robots can automatically clean areas to be cleaned by direct scraping and vacuuming dust absorption techniques. Scraping tasks can be performed by a doctor blade and a rotating brush attached to the bottom of the automatic vacuum cleaner.

[0003] When an automatic cleaning robot with a ground wiping function is used to wipe the ground, it is necessary to install a water tank on the automatic cleaning robot to supply water required for wiping the ground. The water tank of a conventional automatic cleaning robot is located at the bottom of the robot body and connected to the robot. Usually, when attaching or removing the water tank, it is necessary to turn the robot over so that the bottom of the robot faces upward, and then the water tank is attached or removed. Since it is necessary to turn the robot over when attaching or removing the water tank, the top of the robot is easily hit or damaged, and further, the sensor attached to the top of the robot is easily damaged, which may result in a large economic loss. In addition, if water leaks from the water tank, when the water tank is attached or removed, the leaked water may flow into the inside of the robot through a gap at the bottom of the robot, causing damage to the internal circuits and parts, which may become unrepairable.

[0025] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a liquid storage case and an intelligent cleaning device having the same according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0026] Meaning of the name: Forward direction: refers to the forward direction of the intelligent cleaning device. Reverse direction: refers to the direction opposite to the forward direction of the intelligent cleaning device.

[0027] In an embodiment of the present invention, a liquid storage case is provided. The liquid storage case includes a storage case, and the storage case is formed with a water outlet 321. The water outlet 321 is connected to the liquid storage space in the storage case, and a water outlet control nozzle 34 is installed in the water outlet 321 to control the water outlet speed. By installing the water outlet 321 with the water outlet control nozzle 34 for controlling the water outlet speed, the amount of water outlet can be controlled by the filtering structure of the water outlet control nozzle 34. In the conventional technology, a permeable cloth is installed in the water tank, and one end of the permeable cloth is installed in the water storage space and the other end is installed in the water outlet, and the water in the water tank is guided to the water outlet by capillary action. When the water outlet is controlled by the filtering structure, the problem of the conventional technology that the water outlet speed cannot be easily controlled when the water outlet is controlled by the permeable cloth can be solved. In addition, since the entire permeable cloth is installed inside the storage case, replacement of the permeable cloth is inconvenient, costly, and requires dismantling the water tank, which makes use complicated and does not facilitate replacement. If the water outlet control nozzle 34 is attached to the water outlet 321, replacement becomes easy.

[0028] In this embodiment, the permeable cloth inside the liquid storage case is removed, and the water outflow speed can be controlled only by the water outflow control nozzle 34, so that the water outflow control effect is further improved.

[0029] In this embodiment, the liquid container is attached to an intelligent cleaning device (e.g., a cleaning robot) and is used to store cleaning liquid (e.g., water) for the intelligent cleaning device. In other embodiments, the liquid container can be applied to other suitable environments.

[0030] Preferably, the container case includes an upper cover 31 and a lower cover 32 , the upper cover 31 is coupled to the lower cover 32 , and the water outlet 321 is formed in the lower cover 32 .

[0031] Alternatively, the water outlets 321 may be multiple and spaced apart on the receiving case. The number of water outlets 321 may be increased or decreased according to the need for different water flow rates. With two water outlets 321, the water flow rate is ensured and the frequency of water supply can be avoided due to the fast water flow rate. Of course, the water flow rate of each water outlet 321 can be controlled by adjusting the area of ​​the water outlets 321.

[0032] Optionally, the water outflow control nozzle 34 includes a nozzle core 342. The nozzle core 342 is inserted into the water outflow port 321 to close the water outflow port 321, so that the liquid in the liquid storage case flows out by permeation of the nozzle core 342. The water outflow speed can be controlled by controlling the permeation speed of the nozzle core 342, which solves the problem of the prior art that it is difficult to control the water outflow speed when water is outflowed using a permeable cloth.

[0033] Optionally, the water outflow control nozzle 34 includes a nozzle frame 341 and a nozzle core 342. The nozzle frame 341 is detachably mounted in the water outlet 321. The nozzle frame 341 is formed with a receiving hole penetrating the nozzle frame 341, and the nozzle core 342 is received in the receiving hole. As shown in Figs. 24 and 25, by adopting the water outflow control nozzle 34 having the above-mentioned structure, the nozzle frame 341 is mounted in the water outlet 321 of the lower cover 32, and then the water outflow amount can be controlled by the nozzle core 342. Since the nozzle frame 341 is inserted into the water outlet 321 from the outside of the lower cover 32 (the side away from the upper cover 31), the water outflow control nozzle 34 can be replaced without dismantling the housing case, and the replacement of parts is easy. The water outflow amount can be controlled by selecting nozzle cores 342 with different permeabilities, so that the water outflow amount can be more accurately and well controlled, and the cleaning effect can be ensured.

[0034] In order to ensure that the water in the container case flows into the nozzle core 342, the nozzle frame 341 is provided with water inlet holes 341a. The water inlet holes 341a communicate with the container hole and the liquid container space. Optionally, the water inlet holes 341a are formed in the nozzle frame 341 and spaced apart along the periphery of the nozzle frame 341.

[0035] In other embodiments, the water outflow control nozzle 34 may include only a nozzle core 342 to allow for control of the water outflow rate.

[0036] Preferably, the number of the water outflow control nozzles 34 is two or more, and each water outflow control nozzle 34 corresponds to each water outlet 321 one by one. The number of the water outflow control nozzles 34 can be appropriately selected according to the area of ​​the cleaning cloth 4 and the predetermined humidity. More preferably, the number of the water outflow control nozzles 34 is two, and the distance between them is 10mm to 350mm, so as to ensure that the entire cleaning cloth 4 is uniformly wet. More preferably, the distance between them is 80mm to 90mm. The water outflow control nozzle 34 further includes an abutting sealing spacer 343, and the abutting sealing spacer 343 is installed at one end of the nozzle frame 341. The receiving case is formed with a recess, which is formed on the outer periphery of the water outlet 321, and the abutting sealing spacer 343 is located within the recess. Preferably, the water outflow control nozzle 34 further includes a contact sealing spacer 343 (which may be made of rubber), and the contact sealing spacer 343 is attached to one end of the nozzle frame 341 that is remote from the upper cover 31, and a recess is formed on one side of the lower cover 32 that is remote from the upper cover 31 to accommodate the contact sealing spacer 343. The contact sealing spacer 343 prevents liquid from leaking out from the gap between the water outlet and the water outflow control nozzle 34, and provides an operating position to facilitate attachment and detachment of the water outflow control nozzle 34. By controlling the water outflow rate with the water outflow control nozzle 34, replacement of parts becomes more convenient. In addition, the water outflow rate can be controlled by adopting nozzle cores 342 made of different materials according to the needs of different environments, and users can conveniently select them.

[0037] Preferably, in order to improve the climbing and cross-country ability of the intelligent cleaning device and to allow the intelligent cleaning device to be applied to various environments, the liquid storage case further includes a cross-country auxiliary roller 322, which is rotatably installed on the storage case. The cross-country auxiliary roller 322 protrudes from the surface of the storage case at its location. For ease of understanding, the function of the cross-country auxiliary roller 322 will be described in conjunction with the intelligent cleaning device to which it is applied.

[0038] In another embodiment of the present invention, an intelligent cleaning device is provided, which includes a device body 1 and a cleaning system. The device body 1 is used to support the cleaning system and other structures installed in the device body 1, and the cleaning system includes a first cleaning part 2 detachably installed in the device body 1. When the first cleaning part 2 is attached to the device body 1 or detached from the device body 1, the first cleaning part 2 moves along the forward direction of the device body 1. The first cleaning part 2 includes a liquid storage case 3, which is the above-mentioned liquid storage case. When the first cleaning part 2 is attached to the device body 1 or detached from the device body 1, the first cleaning part 2 moves along the forward direction (or the opposite direction) of the device body 1. Since the forward direction of the device body 1 is usually horizontal, it is more convenient to attach and detach the first cleaning part 2, and it is possible to solve the problem in the prior art that the automatic cleaning robot cannot be attached or detached without turning it over so that its bottom faces upward. Therefore, it is more convenient to replace and maintain the first cleaning part 2. By employing liquid storage case 3 having the above-described structure, the water outflow effect can be improved and the cleaning effect can be ensured.

[0039] As shown in Figures 1 and 2, the intelligent cleaning device may be an intelligent cleaning robot, but is not limited thereto, and may be a solar panel cleaner, a building exterior cleaner, etc. In this embodiment, an intelligent cleaning robot will be described as an example.

[0040] The intelligent cleaning device includes not only a device body 1 and a cleaning system, but also a sensing system, a control system (not shown), a driving system, an energy system, and a man-machine interface 9. The main components of the intelligent cleaning device will be described in detail below.

[0041] The device body 1 includes an upper closed cover, a forward section 13, a backward section 14, and a chassis 11. The device body 1 has a generally circular shape (both the front and rear are circular), and can also have other shapes, for example, a generally D-shape with a square front and a circular rear, but is not limited thereto.

[0042] The sensing system includes a position determining device located above the device body 1, a buffer device located at the forward portion 13 of the device body 1, a step sensor 51, and sensors such as an ultrasonic sensor, an infrared sensor, a magnetometer, an accelerometer, a gyroscope, and an odometer. These sensors transmit the position information and moving status information of the intelligent cleaning device to the control system. The position determining device can include, but is not limited to, an infrared transmitter-receiver, a camera, and a laser distance measuring device (LDS).

[0043] The cleaning system includes a dry cleaning unit and a wet cleaning unit. The wet cleaning unit is a first cleaning unit 2, whose function is to wipe the surface to be cleaned (e.g., the ground) with a cleaning cloth 4 containing cleaning liquid. The dry cleaning unit is a second cleaning unit, whose function is to sweep solid particles of dirt off the surface to be cleaned by using a structure such as a brush.

[0044] As a dry cleaning unit, the main cleaning function is performed by the second cleaning unit, which is composed of the rotating brush 61, the dust storage unit, the blower, the air outlet, and the connecting parts between them. The rotating brush 61, which is in contact with the ground to a certain extent, sweeps up the dust on the ground and guides it to the front of the dust suction port between the rotating brush 61 and the dust storage unit. The dust is guided into the dust storage unit by the suction gas formed by the blower and passing through the dust storage unit. The cleaning ability of the vacuum cleaner can be indicated by the dust pick up efficiency DPU. The dust pick up efficiency DPU is affected by the structure and material of the rotating brush 61, the wind power utilization rate of the air passage composed of the dust suction port, the dust storage unit, the blower, the air outlet, and the connecting parts between them, and the type and power of the blower. Compared with ordinary electric input vacuum cleaners, the improvement of dust removal ability is of even greater significance for energy-limited cleaning robots. By improving the dust removal ability, the demand for energy can be effectively reduced. For example, originally, the vacuum cleaner could clean 80 square meters of ground with one charge, but after improving the dust removal ability, the vacuum cleaner can clean more than 100 square meters of ground with one charge. By reducing the number of charges, the service life of the battery can be significantly increased, and the frequency with which the user replaces the battery can be reduced. More importantly, the improved dust removal ability allows the user to obtain a noticeable feeling of use, and the user can conclude whether the ground has been swept cleanly or wiped cleanly. The dry cleaning system can further include a side brush 62 having a rotating shaft. Since the rotating shaft has a certain angle relative to the ground, the dust can be guided to the cleaning area of ​​the rotating brush 61 of the second cleaning unit.

[0045] The first cleaning unit 2, which is a wet cleaning unit, mainly includes the above-mentioned liquid storage case 3 and cleaning cloth 4. The liquid storage case 3 is an important component that supports the first cleaning unit 2. The cleaning cloth 4 is detachably attached to the liquid storage case 3. The liquid in the liquid storage case 3 flows into the cleaning cloth 4, and the cleaning cloth 4 wipes the ground that has been cleaned by the rotating brush or the like.

[0046] The driving system drives the device body 1 and the components thereon to move, so that the intelligent cleaning device automatically travels and cleans. The driving system includes a roller driving module 71, which outputs a driving command based on distance and angle information, such as the quantities x, y, and θ, to make the cleaning robot move on the ground. The roller driving module 71 can simultaneously control the left and right rollers. In order to precisely control the movement of the cleaning robot, it is preferable that the roller driving module 71 includes a left roller driving module and a right roller driving module, respectively. The left roller driving module and the right roller driving module are provided on both sides of the lateral axis of the device body 1 (symmetrically provided). In order to make the cleaning robot move more stably or have stronger movement ability on the ground, the cleaning robot can include one or more driven rollers 72. The driven rollers can be omnidirectional rollers, but are not limited thereto.

[0047] The roller driving module 71 includes a traveling roller, a driving motor, and a control circuit for controlling the driving motor. The roller driving module 71 may further include a circuit for measuring a driving current and an odometer. The roller driving module 71 is detachably connected to the device body 1, which makes it easy to install, remove, and maintain. The driving roller includes an offset-mounted downward suspension device, which is fixed in a movable manner, for example, fixed to the device body 1 in a rotatable manner, and is offset-mounted by receiving a downward force and a force away from the device body 1 by an offset mounting spring. The offset mounting spring allows the driving roller to maintain contact and traction with the ground with a constant landing force, and also allows the cleaning parts (e.g., the rotating brush) of the cleaning robot to contact the ground with a constant pressure.

[0048] A buffer device can be attached to the forward moving part 13 of the device body 1. When the cleaning robot moves on the ground by driving the roller driving module 71 during the cleaning process, the buffer device detects one or more obstacles on the path of the cleaning robot by a sensor system such as an infrared sensor. Based on the obstacles detected by the buffer device, such as an obstacle, a wall, etc., the cleaning robot can control the roller driving module 71 to take measures to avoid the obstacles. For example, the cleaning robot can move in a direction away from the obstacle.

[0049] The control system is installed on a circuit board in the device body 1 and includes a non-volatile memory such as a hard disk drive, a flash memory, a random access memory, a central processing unit, and a communication and computing device such as an application processor. The application processor obtains the obstacle information fed back by the laser distance measuring device, and then forms a real-time map of the environment where the cleaning robot is located by a localization calculation method, for example, SLAM. The control system determines the current situation of the cleaning robot by combining the distance information and speed information fed back by the buffer device, the step sensor 51, and sensors such as an ultrasonic sensor, an infrared sensor, a magnetometer, an accelerometer, a gyroscope, and an odometer. For example, it determines whether the cleaning robot is on a threshold or carpet, is located near a step, is hanging up or down, the dust container is full, is being held, etc. Therefore, it provides the next operating countermeasure according to different situations. As a result, the cleaning robot operates according to the user's intention and can obtain a better user experience. The control system can plan the most effective cleaning route and cleaning method according to the real-time map formed by SLAM, so that the cleaning efficiency of the cleaning robot can be greatly improved.

[0050] The energy system includes a rechargeable battery such as a nickel metal hydride battery or a lithium battery. The rechargeable battery is connected to a charging control circuit, a battery group charging temperature detection circuit, and a battery low voltage detection circuit, and the charging control circuit, the battery group charging temperature detection circuit, and the battery low voltage detection circuit are connected to a single-chip control circuit. The device body is charged by connecting a charging electrode provided on one side or below the device body to a charging pile. If dust is attached to the exposed charging electrode, the plastic around the charging electrode may melt and deform due to the accumulation of electric charge generated during the charging process, which may cause the shape of the charging electrode to be deformed and prevent normal charging.

[0051] The man-machine interface 9 includes a keyboard on a panel of the device body, and the user can select functions through the keyboard. The man-machine interface 9 can further include a display panel and / or an indicator lamp and / or a speaker, and the display panel, the indicator lamp and the speaker can show the user the current state of the cleaning robot or a selected function. The man-machine interface 9 can further include a program for a mobile phone terminal. The route guide type cleaning device can provide the user with a map of the environment where the cleaning robot is located and the location of the cleaning robot through the mobile phone terminal, and therefore can provide the user with more abundant and better functions.

[0052] In order to describe the movement of the cleaning robot in more detail, the direction of movement is defined below. It can be shown that the cleaning robot moves on the ground by moving along three vertical axes formed by the device body 1. The three vertical axes refer to the front-rear axis X (the axis along the direction of the forward portion 13 and the backward portion 14 of the device body 1), the lateral axis Y (the axis perpendicular to the X axis and located in the same horizontal plane as the X axis) and the central vertical axis Z (the axis perpendicular to the plane formed by the X axis and the Y axis). The direction of driving along the forward direction of the front-rear axis X is called the "forward direction", and the direction of driving along the backward direction of the front-rear axis X is called the "backward direction". The lateral axis Y means extending between the right roller and the left roller along the axis defined by the center point of the roller driving module 71.

[0053] The cleaning robot can rotate around the Y axis. When the forward moving part of the cleaning robot is tilted upwards and the backward moving part is tilted downwards, it is called "facing upwards", and when the forward moving part of the cleaning robot is tilted downwards and the backward moving part is tilted upwards, it is called "facing downwards". The cleaning robot can rotate around the Z axis. When the cleaning robot is tilted to the right of the X axis in the forward moving direction of the cleaning robot, it is called "rotating right", and when the cleaning robot is tilted to the left of the X axis, it is called "rotating left".

[0054] The dust receptacle can be coupled to the receptacle by providing a mechanical coupling such that when the coupling is pressed the hook is contracted and when the coupling is released the hook returns to its original shape, thereby coupling the hook to a recess in the receptacle that receives the hook.

[0055] Hereinafter, the specific connection between the first cleaning part 2 and the device body 1 will be described in detail.

[0056] The first cleaning part 2 is attached to the device body 1 by a guide structure, and after the first cleaning part 2 is attached to the device body 1, the first cleaning part 2 can move up and down relative to the device body 1. That is, a gap is formed between the first cleaning part 2 and the device body 1.

[0057] Specifically, the first cleaning unit 2 is mounted on the chassis 11 of the device body 1. A protrusion structure 113 for mounting the first cleaning unit 2 is formed on the chassis 11. In this embodiment, the first cleaning unit 2 is mounted on the chassis 11 at the recessed portion 14 of the device body 1.

[0058] The first cleaning part 2 is attached to the chassis 11 by a guide structure, and a gap is formed between the first cleaning part 2 and the chassis 11.

[0059] 3 to 10, the guide structure includes a first guide protrusion 311 and a first guide groove 111. The first guide groove 111 is formed on one of the first cleaning part 2 and the chassis 11, and the first guide protrusion 311 is formed on the other of the first cleaning part 2 and the chassis 11.

[0060] In this embodiment, the first guide groove 111 is formed on the side wall of the protrusion structure 113 of the chassis 11. The first guide protrusion 311 is formed on the liquid containing case 3 of the first cleaning unit 2, and when the liquid containing case 3 and the chassis 11 are combined, the first guide protrusion 311 is inserted into the chassis 11 to achieve the functions of guiding and stopping. As shown in Fig. 11, a recess is formed in the liquid containing case 3 to avoid the protrusion structure 113 of the chassis 11.

[0061] Preferably, in order to conveniently install the liquid storage case 3, the thickness of the first guide protrusion 311 is made smaller than the width of the first guide groove 111 (the width of the first guide groove 111 refers to the width between the two opposing sides of the first guide groove 111, which refers to the vertical distance between the two opposing sides when the cleaning robot is in a horizontal position). Therefore, when the first guide protrusion 311 is inserted into the first guide groove 111, a gap is formed between the first guide protrusion 311 and the two opposing sides of the first guide groove 111, thereby achieving a gap fit between the liquid storage case 3 and the chassis 11, and allowing the user to conveniently install the liquid storage case 3.

[0062] The size of the gap between the liquid storage case 3 and the chassis 11 can be determined according to actual needs. In this embodiment, the size of the gap between them ranges from 1.5 mm to 4 mm. Preferably, the size of the gap between them is 2 mm. In this case, when the user inserts the liquid storage case 3 into the chassis 11 without standing the cleaning robot upside down, a sufficient gap can be provided for insertion. Therefore, the user can easily insert the liquid storage case 3 into the chassis 11 without precisely aligning the liquid storage case 3 with the chassis 11. In the conventional cleaning robot, the user cannot attach the water tank unless the cleaning robot is stood upside down (with the bottom facing up). This makes it difficult to use and remove, and when water leaks from the water tank, the water may flow into the inside of the cleaning robot and damage the cleaning robot.

[0063] In this embodiment, the first cleaning part 2 is attached to the device body 1 along the forward or backward direction of the device body 1, and then connected to the device body 1 by a connecting structure. The connecting structure includes a first connecting structure located on the device body 1 and a second connecting structure located on the first cleaning part 2.

[0064] Preferably, in order to conveniently control the connection and disconnection between the first cleaning part 2 and the device body 1, the connection structure further includes a connection control system, which can control the connection and disconnection between the first connection structure and the second connection structure. The connection control system is located in the first cleaning part 2 or the device body 1.

[0065] Preferably, the coupling control system is installed in the first cleaning section 2 .

[0066] In this embodiment, the connection structure is a connection structure, and the liquid storage case 3 and the chassis 11 are connected by the connection structure. When the connection is made by the connection structure, the connection is convenient and the connection is stable. In other embodiments, other connection structures, such as a magnetic attraction structure, can be adopted as the connection structure. The liquid storage case 3 and the chassis 11 can be connected by other connection structures, such as a magnetic attraction structure. The connection control system can be a connection control system or a magnetic attraction control system, and can be any system that ensures convenience in use and attachment / detachment.

[0067] A specific embodiment in which the liquid storage case 3 and the chassis 11 are connected by a coupling structure will be described in detail below.

[0068] Referring to FIG. 7, the chassis 11 is formed with a first connecting structure, which may be a first coupling part 112, an electromagnet, a magnetic conductor, or the like. When the first coupling part is adopted, the first coupling part 112 is used for coupling with the liquid storage case 3, thereby fixing the liquid storage case 3. Referring to FIG. 11 to FIG. 17, the liquid storage case 3 is formed with a second connecting structure, which may be a second coupling part 331 coupled with the first coupling part 112, an electromagnet, a magnetic conductor, or the like. The first coupling part 112 and the second coupling part 331 form a coupling structure. The second coupling part 331 has a stop position and a yield position. As shown in FIG. 18, when the second coupling part 331 and the first coupling part 112 are in a non-movable state, the liquid storage case 3 is coupled to the chassis 11. When the second coupling part 331 and the first coupling part 112 are in a yield position, the liquid storage case 3 is coupled to the chassis 11.

[0069] The connection control system includes a connection control module 33 for controlling the connection and separation of the first connection part 331 and the second connection part 331. The connection control module 33 controls the position of the second connection part 331 to connect or separate the second connection part 331 and the first connection part 112. When using the cleaning robot, a user can control the position of the second connection part 331 by controlling the connection control module 33, i.e., control the connection and fastening or separation of the liquid storage case 3 and the chassis 11, thereby conveniently installing or removing the liquid storage case 3.

[0070] Specifically, a chamber for mounting the connection control module 33 and the second connection part 331 is formed in the upper cover 31 of the liquid storage case. The connection control module 33 is mounted in the upper cover 31, and an opening 312 is formed on the upper cover 31 into which the first connection part 112 is inserted and to which the second connection part 331 is connected.

[0071] The liquid storage case 3 also includes a storage case, which is composed of an upper cover 31 and a lower cover 32, and a liquid storage space is formed within the storage case. In this embodiment, the liquid stored in the liquid storage case 3 is water, but in other embodiments, any cleaning liquid can be stored in the liquid storage case 3 according to needs.

[0072] As shown in FIGS. 14 to 17, the coupling control module 33 includes a mounting frame 332, an operating part 333, and an elastic part 334, etc.

[0073] The second coupling part 331 is fixed to the mounting frame 332, which is movably installed in the storage case and moves the second coupling part 331 to a stop position or a yield position in conjunction with the mounting frame 332. The operating part 333 is installed on the mounting frame 332 so as to be integral with the mounting frame 332. When a user presses the operating part 333, the operating part 333 moves together with the mounting frame 332 and the second coupling part 331 thereon in conjunction with the mounting frame 332.

[0074] In order to ensure that the second coupling part 331 returns to the stop position when the pressure is removed, and that the liquid storage case 3 is stably connected to the chassis 11, an elastic part 334 (the elastic part 334 is a structure capable of providing elasticity, such as a spring, elastic rubber, etc.) is installed between the operating part 333 and the container case of the liquid storage case 3. A first end of the elastic part 334 abuts against the operating part 333 or the mounting frame 332, a second end of the elastic part 334 abuts against the container case, and the direction of expansion and contraction of the elastic part 334 coincides with the moving direction of the operating part 333. When the pressure is removed, the elasticity of the elastic part 334 can stop the second coupling part 331 at the stop position. When the user wants to remove the liquid storage case 3, the user pushes the operating part 333 to move the second coupling part 331 to the yielding position. This allows the first joint portion 112 and the second joint portion 331 of the chassis 11 to be separable, so that the liquid storage case 3 can be removed.

[0075] 13, in order to restrict the movement of mounting frame 332 and prevent mounting frame 332 from coming off liquid containing case 3 due to the elasticity of elastic part 334 if there is no restriction, stop protrusions 313 are formed on the container case of the liquid containing case, and holes are formed in mounting frame 332 into which stop protrusions 313 are inserted. Stop protrusions 313 are coupled to inner walls 332a of the holes, thereby restricting the movement of mounting frame 332.

[0076] In this embodiment, a first end of the elastic element 334 abuts against the operating element 333, and a second end of the elastic element 334 abuts against the stop protrusion 313. The operating element 333 and the stop protrusion 313 are separately formed with cross-shaped protrusions for mounting the elastic element 334.

[0077] The specific process of mounting the liquid storage case 3 to the chassis 11 is as follows. As shown in Figures 3 and 4, when the liquid storage case 3 is inserted into the rear part of the chassis 11 along the first guide groove 111 of the chassis 11, the overall appearance of the intelligent automatic cleaning robot is formed. The chassis 11 of the cleaning robot is formed with a first connecting part, which is a hook in a specific embodiment. The hook is connected to the second connecting part of the liquid storage case, which is a fastener in a specific embodiment, so that the liquid storage case can be fixed to the bottom of the device body 1. The first guide groove 111 is a U-shaped groove and is slidably coupled to the first guide protrusion 311 of the liquid storage case, so that the liquid storage case 3 can slide on the chassis 11.

[0078] After the liquid storage case 3 is attached to the chassis 11, when the liquid storage case is to be removed from the chassis, the operating part 333 of the connection control module 33 is pressed to overcome the elasticity of the spring and transmit force to cause the second connection part 331 to retreat in the liquid storage case 3 (in a natural state, the second connection part 331 is located in the recess of the liquid storage case 3, and when the liquid storage case 3 slides along the first guide groove 111 of the chassis 11 to a connection position, the first connection part 112 (hook) of the chassis 11 is connected to the second connection part 331, thereby moving the second connection part 331 to an area other than the recess. When force is applied to a certain extent, the first connection part 112 (hook) slides into the recess along the slope on the second connection part 331. As a result, the second connection part 331 and the first connection part 112 (hook) are connected to each other, and the liquid storage case 3 can be fixed on the chassis 11). This causes the connection between first connecting portion 112 (hook) and second connecting portion 331 to disappear, and at this time, the liquid storage case can be removed by moving backwards in the direction in which device body 1 moves backwards. In other words, liquid storage case 3 can be removed.

[0079] In another combination control module not shown in the drawings, the combination control module includes a connecting rod 381, a spring 382, ​​a pushing part 383 and a connecting part 384, and the connecting part 384 cooperates with the first connecting part 112 to connect the liquid storage case 3 and the chassis 11. The connecting rod 381 is mounted in the liquid storage case 3, a first end of the connecting rod 381 is formed with the connecting part 384, and a second end of the connecting rod 381 is formed with the pushing part 383, which is rotatably mounted in the liquid storage case 3, a first end of the pushing part 383 is connected with the spring 382, ​​and a second end of the pushing part 383 is an operating end. The spring 382 is connected between the pushing part 383 and the liquid storage case 3. The principle of the combination control module is as shown in FIG. 19.

[0080] 20 to 23, a water inlet 35 is formed in the upper cover 31 of the liquid storage case 3, and liquid can be injected into the liquid storage space through this water inlet. A water inlet flange and a water inlet cover are installed on the water inlet 35, so that the water inlet 35 can be sealed.

[0081] A water outlet 321 is formed in the lower cover 32 of the liquid storage case 3, the water outlet 321 being connected to the liquid storage space, and a water outlet control nozzle 34 for controlling the amount of water flowing out is removably attached to the water outlet 321.

[0082] The lower cover 32 and the upper cover 31 are joined to form a storage case and a liquid storage space for storing liquid. A cleaning cloth 4 can also be attached to the lower cover 32. A surface of the lower cover 32 remote from the upper cover 31 is formed with a plurality of adhesive structures 324. The cleaning cloth 4 is attached to the side of the lower cover 32 remote from the upper cover 31 and placed on the lower cover 32 by the adhesive structure. The adhesive structure 324 can be double-sided tape, Velcro, etc. In order to conveniently replace the cleaning cloth 4, it is preferable that the adhesive structure 324 is Velcro.

[0083] As shown in Figs. 27 to 29, more preferably, the edge of the cleaning cloth 4 is fixed to ensure the correct direction and position of the cleaning cloth 4, thereby preventing the cleaning cloth 4 from tilting and affecting the cleaning effect. In this case, when the cleaning cloth 4 is fixed by other adhesive methods, the edge of the cleaning cloth 4 is not attached in a predetermined direction, and the cleaning cloth 4 cannot be attached correctly, which can be avoided. For example, when a user uses the cleaning cloth, if the cleaning cloth is attached to the water tank at an angle, it may have a large effect on the cleaning effect. The cleaning cloth 4 is formed with a first guide portion, and the liquid storage case 3 is formed with a second guide portion, and the first guide portion and the second guide portion are combined to allow the cleaning cloth 4 to be attached to the liquid storage case 3. The first guide portion may be a guide groove, and the second guide portion may be a guide rod coupled to the guide groove.

[0084] Specifically, a guide slim 44 is formed on the side of the cleaning cloth 4, and an attachment tank 323 is formed in the liquid storage case 3, and the side of the cleaning cloth 4 can be attached to the liquid storage case 3 by inserting the guide slim 44 into the attachment tank 323.

[0085] The guide slim 44 may be a plastic slim or a steel slim having a certain rigidity, or may be a flexible slim. The cross-sectional shape of the guide slim 44 may be a circular or non-circular shape. The cross-sectional shape of the mounting tank 323 of the liquid storage case 3 may be a C-shape or a shape similar to a C-shape, and may be any shape that can store the guide slim 44 and determine its position. The mounting tank 323 has a downward opening (i.e., a C-shaped opening) used to feed the cleaning cloth 4, one end of the mounting tank 323 is an insertion end (the insertion end does not have a stop structure and is used to insert the cleaning cloth 4), and the other end is a stop end (the stop end has a stop structure to prevent the guide slim 44 from coming off the stop end). That is, one end of the mounting tank 323 is sealed and the other end is an opening. The end of the cleaning cloth 4 is fixed to the liquid storage case 3 by the combination of the guide slim 44 and the mounting tank 323, which improves the stability of the fixation and prevents the cleaning cloth 4 from coming off. The guide slim 44 and the mounting tank 323 are located in the liquid storage case 3 in the direction toward the forward movement of the cleaning robot. After the guide slim 44 is attached, the cleaning cloth 4 is adhered to the Velcro to ensure that the cleaning cloth 4 is attached accurately.

[0086] As shown in FIG. 26, the cleaning cloth 4 can be a cleaning cloth made of the same material as a whole, or a composite cleaning cloth made of different materials in different parts. In this embodiment, the cleaning cloth 4 is a composite cleaning cloth, the main body of the cleaning cloth is approximately semicircular, and the inner layer 43 of the cleaning cloth is a permeation area, which is made of a material with high permeability. The middle layer 42 of the cleaning cloth is a contaminant removal area, which is made of a hard material to scrape hard contaminants on the ground. The outer layer 41 of the cleaning cloth is a water absorption area, which absorbs moisture on the ground to remove water logging and water marks. A material with good water absorption effect is adopted as the water absorption area, which can improve the cleaning efficiency. The guide slim 44 is installed on the semicircular straight section.

[0087] The water outlet 321 of the lower cover 32 allows the liquid in the liquid storage space to flow out and wet the cleaning cloth 4. By selecting materials with different filtering structures, the amount of water flowing out can be controlled to meet the needs of the user.

[0088] A cross-country auxiliary roller 322 is installed at the bottom of the liquid storage case 3, which can assist the roller driving module 71 of the intelligent cleaning device when the intelligent cleaning device climbs and crosses the country. The cross-country auxiliary roller supports the liquid storage case 3 of the intelligent cleaning device, thereby improving the climbing and cross-country capabilities.

[0089] Preferably, the cross-country auxiliary roller 322 is rotatably installed on the liquid storage case 3. Specifically, the cross-country auxiliary roller 322 is installed on the lower cover 32 of the liquid storage case 3, and the cross-country auxiliary roller 322 is rotatably installed on the lower cover 32 and is located at the rearward end of the liquid storage case 3. An opening is formed in the cleaning cloth 4 at a position corresponding to the cross-country auxiliary roller 322, and the opening allows the cross-country auxiliary roller 322 to pass through and contact the ground.

[0090] Since the cleaning cloth 4 has an opening, the cross-country auxiliary roller 322 can contact the ground. When the intelligent cleaning device moves on a horizontal ground, the cross-country auxiliary roller 322 does not contact the ground (i.e., when the intelligent cleaning device is in a horizontal state, the lowest point of the cross-country auxiliary roller 322 of the liquid storage case 3 is higher than the lowest point of the traveling roller). When the intelligent cleaning device moves on a slope or goes over a step, the cross-country auxiliary roller 322 comes into contact with the ground. This forms a sliding support point, so that the device body 1 can avoid hanging and can go cross-country. The height of the step that the intelligent cleaning device can go over can be determined according to needs. For example, the height of the step that the intelligent cleaning device can go over can be 17 mm, 19 mm, or a higher step.

[0091] The liquid storage case and the intelligent cleaning device equipped with the same according to the present invention can provide the following advantages. By adopting a coupling structure as a method for connecting the liquid storage case to the device body, a mounting and connecting structure can be formed on the liquid storage case that allows it to be inserted horizontally into the device body. Since the liquid storage case can be directly inserted horizontally into the chassis of the cleaning robot without having to stand the device body upside down, it is possible to greatly improve the convenience of the user in attaching and detaching the liquid storage case.

[0092] Since a gap joint is adopted as a joint method between the liquid storage case and the device body, the user can easily install the liquid storage case (when the gap is small, the user cannot easily insert the liquid storage case unless he or she accurately aligns the position of the liquid storage case, which is inconvenient to use. When there is a sufficient gap, the user can easily insert the liquid storage case and can easily load it even if the liquid storage case is tilted.) In addition, the cross-country ability of the cleaning robot is improved, the cleaning robot is prevented from getting caught (on an obstacle) when cross-country, and when there is an obstacle, the vertical movement of the liquid storage case makes cross-country easier.

[0093] A cross-country auxiliary roller is installed at the bottom of the liquid storage case, and the cross-country auxiliary roller protrudes from the cleaning cloth, and the cross-country auxiliary roller comes into contact with the ground when cross-country. In addition, a gap joint is adopted as the joint method between the liquid storage case and the chassis of the device body, so that the cross-country ability can be greatly improved by the cooperation of the cross-country auxiliary roller and the gap joint. A recess is formed in the center of the liquid storage case, and this recess can be used as a water tank and also as an attachment portion, which is very convenient. The method of controlling the water outflow using the water outflow control nozzle is adopted, and the method of using the permeable cloth is not adopted, so that the convenience of replacement is good and the water outflow speed can be adjusted. The cross-country auxiliary roller is directly attached to the liquid storage case, which can greatly improve the cross-country ability.

[0094] The above are merely specific examples of the present invention, and the scope of protection of the present invention is not limited thereto, and it is understood that those skilled in the art will be able to make design changes within the scope of the present invention without departing from the gist of the present invention. Therefore, the scope of the present invention should be determined by the appended claims. [Explanation of symbols]
