DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present application more apparent and comprehensible, specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to explain the present application and are not intended to limit the present application.

[0031] The present embodiment provides a pool cleaning robot, such as Figure 1 and Figure 2As shown, it comprises a shell 100 and a filter basket 200, a filter cavity 110 is formed in the shell 100, and a water inlet 120 is arranged at the bottom of the filter cavity 110; the filter basket 200 is accommodated in the filter cavity 110, and the filter basket 200 and the shell 100 are detachably connected through a press-type locking mechanism 300.

[0032] The pool cleaning robot provided by the embodiment comprises a shell 100 as a base body and a filter basket 200 for filtering pool water entering the filter cavity 110, and the filter basket 200 and the shell 100 are detachably connected through a press-type locking mechanism 300. In use, the filter basket 200 is loaded into the filter cavity 110 of the shell 100, and the press-type locking mechanism 300 is in a locked state to ensure the firm connection between the filter basket 200 and the shell 100 during the use of the pool cleaning robot, and correspondingly ensure the effective filtration of the pool water through the filter channel formed between the water outlet 221 of the filter basket 200 and the water inlet 120; the pool cleaning robot is placed in the pool, and the water suction assembly 160 installed in the shell 100 is started to suck the filter cavity 110 into a negative pressure state, the pool water flows into the filter basket 200 through the water inlet 120 under the action of pressure difference, and then flows along the filter channel, and after the filtering action of the filter element 216 in the filter basket 200, the pool water reflows into the pool through the water outlet 221, and the impurities filtered by the filter element 216 are blocked in the filter basket 200, thereby realizing the filtering and cleaning treatment of the pool water.

[0033] When the pool cleaning is completed or the filter basket 200 needs to be cleaned, the user can hold the pool cleaning robot with one hand to make it separate from the water surface, and press the press-type locking mechanism 300 between the filter basket 200 and the shell 100 with the other hand to make it in an unlocked state, and then take out the filter basket 200 from the filter cavity 110, so that the stored water in the filter basket 200 can be discharged through the main drain 211 of the basket wall or the basket bottom, and the filter screen at the main drain 211 can intercept the impurities in the filter basket 200; at the same time, after the filter basket 200 is taken out, the water inlet 120 of the filter cavity 110 is in an open state, and the stored water in the filter cavity 110 can be discharged through the water inlet 120, so that during the process of holding the pool cleaning robot upwards, the user only needs to perform a simple pressing operation on the press-type locking mechanism 300 to quickly and conveniently detach the filter basket 200 from the shell 100 and take it out as a whole, so that the stored water in the filter cavity 110 and the filter basket 200 is quickly discharged, and then the user can load the filter basket 200 into the filter cavity 110 again, or hold the shell 100 and the filter basket 200 with both hands, after the above operation, the user only needs to bear the weight of the pool cleaning robot itself during the subsequent process of moving the pool cleaning robot, without bearing the weight of the stored water in the filter cavity 110 and the filter basket 200, thereby improving the moving convenience and use convenience of the pool cleaning robot.

[0034] Optionally, the shell 100 can be fixed with a fixed handle 170, and the user can lift the cleaning robot by applying force to the fixed handle 170. Specifically, as shown in Figure 2 The bottom of the filter basket 200 is provided with a communication hole 212 at a position corresponding to the water inlet 120. One side edge of the communication hole 212 is hingedly connected with a blocking cover 213. When the blocking cover 213 is rotated to the communication hole 212, the blocking cover 213 can block the communication hole 212. When the filter basket 200 is loaded into the filter cavity 110, the communication hole 212 is in communication with the water inlet 120, and the water outlet 221 is in communication with the output port of the water pumping assembly 160 installed in the shell 100. A filter core 216 is installed in the filter basket 200, and the filter core 216 is located between the communication hole 212 and the water outlet 221. The space between the communication hole 212 and the filter core 216 in the filter basket 200 is a sewage cavity 240 for containing pool water, and the space between the water outlet 221 and the filter core 216 is a clean water cavity 250 for containing clean water after filtration and cleaning treatment. Therefore, the filtration channel includes the water inlet 120, the communication hole 212, the sewage cavity 240, the filter core 216, the clean water cavity 250, and the water outlet 221 in sequence. After the water pumping assembly 160 is started, the filter cavity 110 is in a negative pressure state. The pool water flows into the communication hole 212 through the water inlet 120 and pushes up the blocking cover 213, and then flows into the sewage cavity 240. The pool water flows to the clean water cavity 250 after being filtered by the filter core 216. The impurities in the pool water are blocked in the sewage cavity 240, and the filtered clean water then flows back into the pool through the water outlet 221 under the drive of the water pumping assembly 160. The process is repeated to complete the continuous cleaning treatment of the pool water. Preferably, the blocking cover 213 can be connected with a limiting piece 214. During the process of the blocking cover 213 being rotated and opened under the action of water flow, the limiting piece 214 abuts against the limiting table of the filter basket 200 or the limiting table arranged in the filter basket 200, so as to limit the maximum rotation of the blocking cover 213, thereby reducing the occurrence of the situation that the blocking cover 213 cannot be rotated to block the communication hole 212 when the rotation angle of the blocking cover 213 is greater than 90°.

[0035] After the cleaning treatment of the pool water is completed, the water pumping assembly 160 is closed, and the pool water no longer pushes up the blocking cover 213. After the cleaning robot is separated from the water surface, the stored water in the filter basket 200 exerts a downward pressure on the blocking cover 213, and the blocking cover 213 blocks the communication hole 212 to reduce the occurrence of the situation that the impurities in the sewage cavity 240 leak out through the communication hole 212 to cause secondary pollution to the pool water. The press-type locking mechanism 300 is pressed, the filter basket 200 is unlocked from the shell 100, the filter basket 200 is lifted outwards, the stored water in the filter basket 200 can be discharged through the main drain port 211, and the stored water in the filter cavity 110 is discharged through the open water inlet 120.

[0036] Specifically, in the embodiment, as shown in Figure 3 and Figure 4As shown, the press-type locking mechanism 300 comprises a lock slot 310 arranged on the shell 100 and a lock tongue 320 slidingly connected to the filter basket 200; the filter basket 200 is provided with a button 330, the button 330 is connected with the lock tongue 320 through a linkage mechanism, and when the button 330 is in a natural position, the lock tongue 320 is inserted into the lock slot 310; when the button 330 is in a pressed position, the lock tongue 320 is separated from the lock slot 310; a first elastic reset member 360 is connected between the button 330 and the filter basket 200, and the first elastic reset member 360 is used to drive the button 330 to move towards the natural position. Here is a specific form of the press-type locking mechanism 300, when the user does not exert a pressing force on the button 330, the button 330 is in the natural position under the reset action of the first elastic reset member 360, and the lock tongue 320 is correspondingly in the extended state; when the user overcomes the reset force of the first elastic reset member 360 and presses the button 330 to the pressed position, the button 330 drives the lock tongue 320 to retract through the linkage mechanism. When installing the filter basket 200 into the filter cavity 110, the button 330 can be pressed to the pressed position, the lock tongue 320 retracts, and the first elastic reset member 360 is compressed, the filter basket 200 is installed into the filter cavity 110, the button 330 is released, and the button 330 returns to the natural position under the restoring action of the first elastic reset member 360, the lock tongue 320 is linked to extend and is inserted into the lock slot 310, thereby realizing the locking of the filter basket 200 and the shell 100. When the cleaning robot finishes cleaning or needs to clean the filter basket 200, the button 330 can be pressed, the lock tongue 320 retracts and separates from the lock slot 310, thereby taking out the filter basket 200.

[0037] Among them, the button 330 is in the natural position under the reset action of the first elastic reset member 360 when it is not subjected to external force, and the lock tongue 320 is correspondingly in the extended state, which can ensure the insertion locking with the lock slot 310, that is, after the filter basket 200 is installed into the filter cavity 110, the button 330 is not subjected to external force, and the locking with the lock slot 310 is necessarily in the locked state, thereby improving the locking firmness of the filter basket 200 and the shell 100, and reducing the occurrence of the situation that the filter basket 200 is placed in the filter cavity 110 but not locked due to user's mistaken operation, and the filter basket 200 separates from the filter cavity 110 during the cleaning process. Of course, when the pool cleaning robot is not provided with the first elastic reset member 360, the user can also manually pull out the button 330 to drive the lock tongue 320 to keep the locking with the lock slot 310.

[0038] Preferably, the axial directions of the lock slot 310 and the lock tongue 320 are consistent with the width direction of the shell 100, that is, consistent with the left-right direction when the cleaning robot is used, so as to ensure that the lock slot 310 limits the lock tongue 320 along the depth direction of the filter cavity 110.

[0039] Of course, in other embodiments, the press-type locking mechanism 300 can also adopt other forms, such as a Beatles press switch, both the locking column and the lock core of the Beatles press switch, one of which is mounted on the bottom of the filter basket 200, and the other is mounted on the bottom of the filter cavity 110, when the filter basket 200 is loaded into the filter cavity 110, the two clamping jaws of the lock core clamping the locking column to achieve the locking of the filter basket 200 and the shell 100; when it is needed to take out the filter basket 200, press down the filter basket 200, the two clamping jaws of the lock core release the locking column, and the filter basket 200 can be taken out outward.

[0040] Optionally, in the present embodiment, the top of the filter basket 200 can also be connected with a handle 230, and the button 330 is located on the handle 230. By setting the handle 230 on the top of the filter basket 200 and setting the button 330 on the handle 230, the user can simultaneously apply force to the handle 230 and press the button 330 with fingers with one hand to load or take out the filter basket 200, thereby greatly improving the convenience of disassembling the filter basket 200, and accordingly further ensuring the rapid drainage of the filter cavity 110 of the cleaning robot, and further ensuring the moving lightness and use convenience of the pool cleaning robot.

[0041] In the present embodiment, as shown in Figure 4 the handle 230 is hollow to form an accommodation cavity 231, the handle 230 is provided with a pressing hole 232 and a first plug hole 233 in communication with the accommodation cavity 231, the button 330 is slidingly plugged in the pressing hole 232, and the lock tongue 320 is slidingly plugged in the first plug hole 233; the linkage mechanism includes a linkage rod 340 located in the accommodation cavity 231, a first end of the linkage rod 340 is connected with the button 330, a second end of the linkage rod 340 is provided with a first sliding surface 341, an end of the lock tongue 320 away from the lock slot 310 is located in the accommodation cavity 231 and is provided with a second sliding surface 321, the second sliding surface 321 is inclined towards the second end of the linkage rod 340 in a direction away from the lock slot 310, and the second sliding surface 321 is in abutting sliding connection with the first sliding surface 341; a second elastic reset member 350 is connected between the handle 230 and the lock tongue 320, and the second elastic reset member 350 is used to drive the lock tongue 320 to move towards the lock slot 310.

[0042] Here is a specific form of the linkage mechanism and its connection with the lock tongue 320, to Figure 4The middle view angle is taken as a reference to illustrate that the accommodating cavity 231 has a space for the button 330, the connecting rod 340 and the lock tongue 320 to move. When the button 330 is not pressed, the button 330 is in a natural position under the restoring action of the first elastic restoring member 360, and the lock tongue 320 is extended and locked with the lock slot 310 under the restoring action of the second elastic restoring member 350. When the filter basket 200 needs to be taken out, the handle 230 is gripped and the button 330 is pressed upward. The first end of the connecting rod 340 moves upward under the pushing action of the button 330, and correspondingly, the second end of the connecting rod 340 moves upward. Since the first sliding surface 341 and the second sliding surface 321 are both inclined downward in the right direction, the first sliding surface 341 exerts a right force on the second sliding surface 321 during the upward movement, the lock tongue 320 is compressed to the right and the second elastic restoring member 350 is separated from the lock slot 310, and then the filter basket 200 can be taken out by the handle 230. When the user stops pressing the button 330, the first elastic restoring member 360 exerts a downward restoring force on the button 330, the button 330 drives the connecting rod 340 to move downward to the natural position, the first sliding surface 341 no longer exerts a right pushing force on the second sliding surface 321, and the second elastic restoring member 350 exerts a left restoring force on the lock tongue 320, and the lock tongue 320 moves to the left.

[0043] Specifically, as shown in Figure 4 , the end of the lock tongue 320 away from the lock slot 310 is provided with a limiting head 322, the limiting head 322 is located in the accommodating cavity 231 and has a size larger than the first insertion hole 233, and the second sliding surface 321 is arranged on the limiting head 322. The size of the limiting head 322 is larger than that of the first insertion hole 233, so that when the first elastic restoring member 360 drives the lock tongue 320 to extend outward by a certain distance, the limiting head 322 can abut against the hole end surface of the first insertion hole 233 to limit the lock tongue 320 from continuing to extend outward, thereby reducing the occurrence of the lock tongue 320 from the first insertion hole 233 and ensuring the normal use of the lock tongue 320.

[0044] Of course, in addition to the above-mentioned connecting rod 340, the linkage mechanism can also adopt a form of a connecting rod mechanism in other embodiments.

[0045] In the embodiment, as shown in Figure 4 , the filter basket 200 is provided with a second insertion hole 222, the first insertion hole 233 is located at the end of the handle 230, and the first insertion hole 233 is surrounded by a hollow insertion column 234, and the insertion column 234 is rotationally inserted into the second insertion hole 222; the top of the filter basket 200 is recessed downward to accommodate the handle 230. Here is a specific connection mode of the handle 230 and the filter basket 200. The end of the handle 230 is rotationally connected to the filter basket 200 through the insertion column 234. When the filter basket 200 needs to be taken out, as shown in Figure 5As shown, the handle 230 can be turned out of the accommodating groove 223 to facilitate the user to exert force on it; after the filter basket 200 is installed, as shown, Figure 1 As shown, the handle 230 can be turned into the accommodating groove 223 to reduce the adverse effects of the outward protrusion of the handle 230 from the shell 100 on the overall appearance of the cleaning robot, and to reduce the resistance of the cleaning robot moving in water, thereby reducing the driving load of the motion driving member of the cleaning robot. The locking tongue 320 is inserted into the first insertion hole 233 and the internal through hole of the insertion column 234 and extends out of the cover 220 through the second insertion hole 222. During the rotation of the handle 230, the locking tongue 320 can be synchronously rotated in the circumferential direction, and the axial expansion and contraction of the locking tongue 320 is not affected, that is, the rotation of the handle 230 does not affect the locking state of the locking tongue 320 and the locking groove 310, which can ensure the locking of the filter basket 200 and the shell 100 by the locking groove 310.

[0046] Preferably, as shown, Figure 1 As shown, one side of the accommodating groove 223 can be recessed to form a recess 224, and the user can insert fingers into the recess 224 to rotate the handle 230 located in the accommodating groove 223, thereby reducing the occurrence of the situation that the handle 230 is embedded in the accommodating groove 223 and the user cannot exert force on the handle 230, and correspondingly further improving the use convenience of the cleaning robot.

[0047] Specifically, in the present embodiment, as shown, Figure 3 As shown, the locking groove 310 is two, and the two locking grooves 310 are located on opposite sides of the shell 100; the locking tongue 320 and the linkage rod 340 are both two, the two locking tongues 320 correspond to the two locking grooves 310 one by one, the two linkage rods 340 correspond to the two locking tongues 320 one by one, and the first ends of the two linkage rods 340 are connected with the button 330. The filter basket 200 and the shell 100 can be locked by the two press-type locking mechanisms 300, so as to firmly lock the opposite sides of the filter basket 200 to the shell 100, thereby ensuring the filtering effect of the filter basket 200 and reducing the occurrence of the situation that the filter basket 200 deviates or even separates from the shell 100, causing the cleaning robot to be unable to normally operate. Specifically, the handle 230 is approximately in the shape of “⌒”, the two first insertion holes 233 are located at the two ends of the handle 230, and correspondingly, the two insertion columns 234 surrounding the two first insertion holes 233 are respectively inserted into the two second insertion holes 222 of the cover 220, that is, the two ends of the handle 230 are rotationally connected to the cover 220; the button 330 can be located at the middle position of the handle 230, and the two linkage rods 340 connected together are consistent with the shape of the handle 230. Pressing a single button 330 can drive the two locking tongues 320 to retract through the linkage of the two linkage rods 340, so as to realize the synchronous control of the two press-type locking mechanisms 300, which is simple in structure and convenient to operate.

[0048] Preferably, the two linkage rods 340 and the button 330 can be integrally formed, which not only can improve the connection firmness and stability of the button 330 and the linkage rods 340, and accordingly ensure the linkage action of the button 330 and the linkage rods 340, but also can reduce the connection and assembly operation of the button 330 and the linkage rods 340.
