[0087] Embodiment one

[0088] The present embodiment discloses a floor brush for cleaning equipment, as shown in the accompanying drawings, comprising: Figures 1-27

[0089] a first cleaning part 1;

[0090] a second cleaning part 2;

[0091] a first liquid supply path at least connecting the first cleaning part 1 and a liquid supply part of the cleaning equipment;

[0092] a second liquid supply path at least connecting the second cleaning part 2 and the liquid supply part of the cleaning equipment;

[0093] a first dirt suction path at least connecting the first cleaning part 1 and a recovery part of the cleaning equipment;

[0094] a second dirt suction path at least connecting the second cleaning part 2 and the recovery part of the cleaning equipment;

[0095] The floor brush comprises a first cleaning state and a second cleaning state. In the first cleaning state, the first cleaning part 1 is in contact with the surface to be cleaned, the first liquid supply path and the first dirt suction path are open, and the second liquid supply path and the second dirt suction path are closed, so as to use the first cleaning part 1 to clean the surface to be cleaned. In the second cleaning state, the second cleaning part 2 is in contact with the surface to be cleaned, the second liquid supply path and the second dirt suction path are open, and the first liquid supply path and the first dirt suction path are closed, so as to use the second cleaning part 2 to clean the surface to be cleaned.

[0096] The floor brush for cleaning equipment (hereinafter referred to as the floor brush) of the present application integrates two independent cleaning mechanisms, and through the switching of the first cleaning state and the second cleaning state, the floor brush can be used to clean at least two different types of surfaces to be cleaned. The application range of the floor brush can be improved, and the cleaning experience of the user can be greatly improved without replacing the cleaning equipment or the floor brush when cleaning complex surfaces to be cleaned.

[0097] Preferably, the first cleaning part 1 and the second cleaning part 2 are different in type. For example, the first cleaning part 1 is a fluff brush for cleaning hard floors, and the second cleaning part 2 is a tufted brush for cleaning carpets.

[0098] ​The types of the first cleaning part 1 and the second cleaning part 2 on the floor brush can be inherent types set at the factory, or the user can purchase multiple cleaning parts at the same time, and select two cleaning parts of appropriate types from the multiple cleaning parts to be installed on the floor brush when in use, so as to meet the cleaning of different types of cleaning surfaces and further improve the cleaning experience of the user. Preferably, the first cleaning part 1 and the second cleaning part 2 are detachably arranged on the floor brush, that is, convenient for cleaning and maintenance, and convenient for replacing the types of the cleaning parts, thereby expanding the application range of the floor brush.

[0099] According to an embodiment of the present application, the first liquid supply path, the second liquid supply path, the first dirt suction path and the second dirt suction path are respectively provided with switches for controlling the opening and closing of these paths, so as to respectively match the first cleaning part 1 and the second cleaning part 2 to perform the cleaning operation. The switches can be mechanical switches controlled manually, or electromagnetic switches controlled electrically, and preferably, the switches are electromagnetic switches, so as to improve the automatic control of the cleaning equipment.

[0100] According to an embodiment of the present application, the floor brush further comprises a switching mechanism configured to at least control the switching between the first cleaning state and the second cleaning state.

[0101] The switching mechanism comprises a first switching state and a second switching state, in the first switching state, the first liquid supply path and the first dirt suction path are opened, the second liquid supply path and the second dirt suction path are closed, and the floor brush is in the first cleaning state; in the second switching state, the second liquid supply path and the second dirt suction path are opened, the first liquid supply path and the first dirt suction path are closed, and the floor brush is in the second cleaning state.

[0102] Specifically, the switching mechanism comprises a dirt suction switching assembly 3 and a liquid supply switching assembly 4, the dirt suction switching assembly 3 is operable to control the opening and closing of the first dirt suction path or the second dirt suction path. Preferably, the dirt suction switching assembly 3 closes one of the first dirt suction path and the second dirt suction path when opening the other one, that is, the dirt suction switching assembly 3 can control the switching between the first dirt suction path and the second dirt suction path; the liquid supply switching assembly 4 is operable to control the opening and closing of the first liquid supply path or the second liquid supply path. Preferably, the liquid supply switching assembly 4 closes one of the first liquid supply path and the second liquid supply path when opening the other one, that is, the liquid supply switching assembly 4 can control the switching between the first liquid supply path and the second liquid supply path.

[0103] According to one preferred embodiment of the switching mechanism, the suction switching assembly 3 and the liquid supply switching assembly 4 are linked together, and the suction switching assembly 3 and the liquid supply switching assembly 4 are in transmission connection, so that one of the suction switching assembly and the liquid supply switching assembly drives the other one to switch synchronously. That is, the suction switching assembly 3 completes switching at the same time as the liquid supply switching assembly 4 completes switching. Specifically, the suction switching assembly 3 opens the first suction passage and closes the second suction passage at the same time as the liquid supply switching assembly 4 opens the first liquid supply passage and closes the second liquid supply passage. Alternatively, the suction switching assembly 3 opens the second suction passage and closes the first suction passage at the same time as the liquid supply switching assembly 4 opens the second liquid supply passage and closes the first liquid supply passage.

[0104] In this way, the suction switching assembly 3 and the liquid supply switching assembly 4 can ensure consistency of opening or closing of the first suction passage and the first liquid supply passage, and consistency of opening or closing of the second suction passage and the second liquid supply passage, thereby ensuring switching stability of the switching mechanism in the first switching state and the second switching state, and finally ensuring switching stability of the floor brush in the first cleaning state and the second cleaning state, and improving the use experience of the floor brush.

[0105] According to one embodiment of the suction switching assembly 3, as shown in Figures 1-19 the suction switching assembly 3 comprises:

[0106] The assembly part 31 is provided with an assembly cavity 311, a first suction inlet 301 and a suction outlet 303 which are in communication with the assembly cavity 311, and the first suction inlet 301 is in communication with the first cleaning part 1.

[0107] The rotating switching part 32 is partially installed in the assembly cavity 311 and can rotate relative to the assembly part 31. The rotating switching part 32 is provided with a first fluid passage, a second fluid passage and a second suction inlet 302 which can be in communication with the second cleaning part 2. One end of the first fluid passage can be in communication with the first suction inlet 301, and the other end of the first fluid passage can be in communication with the suction outlet 303. One end of the second fluid passage is in communication with the second suction inlet 302, and the other end of the second fluid passage can be in communication with the suction outlet 303. Whether the second suction inlet 302 is in communication with the second cleaning part 2 is controlled by rotating the rotating switching part 32, and at the same time whether the first suction inlet 301 is in communication with the first fluid passage is controlled. Preferably, the passage segment of the first fluid passage close to the suction outlet 303 and the passage segment of the second fluid passage close to the suction outlet 303 are integrated together, so that the structure of the rotating switching part 32 is more compact.

[0108] That is, by rotating the rotation switching member 32 to make the first fluid passage communicate with the first dirt inlet 301 and the dirt outlet 303 respectively (i.e. the first dirt suction passage is opened) and close the second dirt inlet 302 (i.e. the second dirt inlet 302 does not communicate with the second cleaning part 2, and the second dirt suction passage is closed), or make the second fluid passage communicate with the dirt outlet 303 and the second dirt inlet 302 communicate with the second cleaning part 2 (the second dirt suction passage is opened), and the first dirt inlet 301 is closed (the first dirt suction passage is closed) at this time, that is, by rotating the rotation switching member 32 to make the first fluid passage form part of the first dirt suction passage and open the first dirt suction passage and close the second dirt suction passage, or make the second fluid passage form part of the second dirt suction passage and open the second dirt suction passage and close the first dirt suction passage.

[0109] The rotation switching member includes a first rotation position (not shown in the figure) and a second rotation position (as shown in Figures 9-11 The first rotation position is when the first fluid passage forms part of the first dirt suction passage, the first fluid passage communicates with the first dirt inlet 301 and the dirt outlet 303 respectively (i.e. the first dirt suction passage is opened), and the second dirt inlet 302 is closed (i.e. the second dirt suction passage is closed); the second rotation position is when the second fluid passage forms part of the second dirt suction passage, the second fluid passage communicates with the dirt outlet 303, and the second dirt inlet 302 communicates with the second cleaning part 2 (i.e. the second dirt suction passage is opened), and the first dirt inlet 301 is closed (i.e. the first dirt suction passage is closed).

[0110] It should be noted that the first dirt suction passage and the second dirt suction passage at least coincide at the dirt outlet 303. Preferably, the first dirt suction passage and the second dirt suction passage have different paths before the dirt outlet 303, and the paths coincide after the dirt outlet 303, that is, the part of the first dirt suction passage that communicates the first cleaning part 1 with the dirt outlet 303 and the part of the second dirt suction passage that communicates the second cleaning part 2 with the dirt outlet 303 have different paths, and the part of the first dirt suction passage that communicates the dirt outlet 303 with the recovery part and the part of the second dirt suction passage that communicates the dirt outlet 303 with the recovery part have the same path. In this way, the first cleaning part 1 and the second cleaning part 2 can be ensured to have independent dirt suction passages that do not affect each other, and the arrangement of the in-brush pipeline can be simplified as much as possible. Specifically, the dirt outlet 303 communicates with the recovery part through the recovery pipeline 33.

[0111] Specifically, the rotation switching member 32 includes a rotating part 321 and an extension part 322 connected to the rotating part 321, the extension part 322 rotates synchronously with the rotating part 321, the extension part 322 extends into the assembly cavity, and the extension part 322 can rotate in the assembly cavity 311.

[0112] The first fluid passage is at least partially located in the extension 322, the side wall of the extension 322 is provided with a communication port 322b in communication with the first fluid passage and a blocking wall 322a matched with the first dirt inlet 301, the communication port 322b and the blocking wall 322a rotate synchronously with the extension. The communication between the communication port 322b and the first dirt inlet 301 or the blocking of the first dirt inlet 301 by the blocking wall 322a is controlled by rotating the extension 322

[0113] The second fluid passage and the second dirt inlet 302 are located in the rotating part 321, the rotating part 321 is located outside the assembly cavity 311 so as to be manually or automatically driven to rotate. Preferably, the rotating part 321 is further provided with a hand holding structure for facilitating the user to hold and rotate the rotating part 321. Whether the second dirt inlet 302 is in communication with the second cleaning part 2 is controlled by rotating the rotating part 321. That is, the switching of the first and second dirt suction passages is controlled by rotating the rotating switching part 32, that is, the communication port 322b is in communication with the first dirt inlet 301 and the dirt outlet 303 (at this time, the first dirt suction passage is opened) while the second dirt inlet 302 is closed (the second dirt inlet 302 is not in communication with the second cleaning part 2, that is, the second dirt suction passage is closed), or the blocking wall 322a blocks the first dirt inlet 301 (at this time, the first dirt suction passage is closed) while the second dirt inlet 302 is opened (the second dirt inlet 302 is in communication with the second cleaning part 2, that is, the second dirt suction passage is opened), at this time, the communication port 322b is in communication with the dirt outlet 303.

[0119] The dirt suction switch assembly 3 is detachably fixed in the first assembly space 34 by the assembly part 31, and specifically, the outer wall of the assembly part 31 is provided with a plurality of assembly lugs 312, that is, the dirt suction switch assembly 3 is detachably fixed in the first assembly space 34 by the assembly lugs 312. The shapes of the plurality of assembly lugs 312 can be the same or different, which is selected according to the specific assembly position of the assembly part 31.

[0120] In order to more accurately define the first and second rotation positions of the rotation switch 32, a limiting structure is arranged between the rotation part 321 and the first assembly space 34. Specifically, the side wall of the rotation part 321 is provided with a first limiting protrusion 321a and a second limiting protrusion 321b, and the first assembly space 34 is provided with a limiting sliding groove 342 matched with the first and second limiting protrusions 321a, 321b.

Preferably, the arc length of the limiting sliding groove 342 is twice the arc length of the side wall between the first and second limiting protrusions 321a, 321b.

[0122] The rotation of the rotation switch 32 is driven manually or / and by electricity. For the convenience of manual driving, the rotation switch 32 is at least partially exposed, specifically, the top of the rotation switch 32 is exposed since the top end of the first assembly space 34 is open, and the top of the rotation switch 32 is provided with an operation part 323 so as to be driven by the user to rotate the rotation switch 32. The top of the rotation part 321 is provided with an assembly groove 321c for assembling the operation part 323.

A spring 323c is further arranged between the first and second operation pieces 323a, 323b. The operation part 323 is thus arranged to facilitate the user to apply force and facilitate assembly. ​

[0124] Preferably, the first operating member 323a and the second operating member 323b are sleeved on one end of the fixed column and form an included angle a, 0° < a ≤ 90°, and an example is a = 15°.

[0125] To avoid the rotation switching member 32 from falling off from the assembly cavity 311 of the assembly member 31, an annular protrusion 322d is arranged on the side wall of the extension 322, and an annular groove is arranged on the inner wall of the assembly cavity 311 and matched with the annular protrusion 322d, the annular protrusion 322d is embedded in the annular groove, which can not only prevent the rotation switching member 32 from falling off from the assembly cavity 311, but also improve the rotation stability of the rotation switching member 32.

[0126] The annular protrusion 322d is located above the blocking wall 322a and the communication port 322b. Preferably, a plurality of annular protrusions 322d are arranged on the side wall of the extension 322, and an example is that two annular protrusions 322d are arranged.

[0127] It should be noted that the structure of the annular protrusion and the annular groove on the side wall of the extension 322 and the inner wall of the assembly cavity 311 can also be exchanged, that is, one of the annular protrusion and the annular groove is arranged on the side wall of the extension 322, and the other is arranged on the inner wall of the assembly cavity 311.

[0128] The liquid supply switching assembly 4 comprises an elastic member 41 and a moving member 42, one end of the moving member 42 abuts against the rotation switching member 32, the other end of the moving member 42 is connected with the elastic member 41, the moving member 42 can rotate and do linear reciprocating motion with the rotation switching member 32, and at the same time, the elastic member 41 is compressed, so as to control one of the first liquid supply passage and the second liquid supply passage to be opened and the other to be closed through the movement of the moving member 42, that is, to control the switching of the first liquid supply passage and the second liquid supply passage through the movement of the moving member 42.

[0129] The moving member 42 comprises a first moving position and a second moving position, in the first moving position, the first liquid supply passage is opened and the second liquid supply passage is closed at the same time, and in the second moving position, the second liquid supply passage is opened and the first liquid supply passage is closed at the same time.

[0130] If the rotation switching member 32 is located at the first rotating position, the moving member 42 is located at the first moving position, and if the rotation switching member 32 is located at the second rotating position, the moving member 42 is located at the second moving position.

[0131] The outer periphery of the rotation switching piece 32 is provided with a switching groove 324 which cooperates with the end of the moving piece 42 away from the elastic piece 41, and the switching of the first liquid supply passage and the second liquid supply passage is controlled by controlling the positional relationship between the moving piece 42 and the switching groove 324. Exemplarily, with the rotation of the rotation switching piece, the end of the moving piece 42 away from the elastic piece 41 can be located in the switching groove 324 or moved out of the switching groove 324 to control the switching of the first liquid supply passage and the second liquid supply passage. Specifically, the first rotation position is that the end of the moving piece 42 away from the elastic piece 41 is away from the switching groove 324, while the first liquid supply passage is opened and the second liquid supply passage is closed, at which time the moving piece 42 is located at the first moving position; the second rotation position is that the end of the moving piece 42 away from the elastic piece 41 is located in the switching groove 324, while the second liquid supply passage is opened and the first liquid supply passage is closed, at which time the moving piece 42 is located at the second moving position, as shown in Figure 10

[0132] It should be noted that the first assembly space 34 is provided with a through hole 343 through which the moving piece 42 passes, and the end of the moving piece 42 away from the elastic piece 41 passes through the through hole 343 and abuts against the rotation switching piece 32.

[0133] Specifically, the switching groove 324 is located on the side wall of the rotating part 321, that is, the moving piece 42 abuts against the side wall of the rotating part 321, and the moving piece 42 reciprocally moves with the rotation of the rotating part 321.

[0134] The shape of the moving piece 42 is similar to an arrowhead, and specifically, the moving piece 42 comprises a sliding rod part 421 and a sliding head part 422, one end of the sliding rod part 421 is connected with the elastic piece 41, the other end of the sliding rod part 421 is connected with the sliding head part 422, and the sliding head part 422 abuts against the rotating part 321.

[0135] In order to ensure the stability of the movement of the moving piece 42, the liquid supply switching assembly 4 further comprises a fixing piece 43 which is provided with a sliding cavity 431 cooperating with the sliding rod part 421, the elastic piece 41 is located in the sliding cavity 431, at least a part of the sliding rod part 421 extends into the sliding cavity 431 and is connected with the elastic piece 41, and the sliding head part 422 is located outside the sliding cavity 431. The extension direction of the sliding cavity 431 is consistent with the reciprocating movement direction of the moving piece 42, the sliding rod part 421 slides in the sliding cavity 431 with the rotation of the rotating part 321, and the sliding cavity 431 guides the reciprocating movement of the sliding rod part 421, thereby improving the stability of the movement of the moving piece 42.

[0136] ​Preferably, the slide rod part 421 is cylindrical in shape, the slide head part 422 is similar to a cone in shape, the bottom of the slide head part 422 is connected with the slide rod part 421, and the vertex of the slide head part 422 is in abutment with the rotating part 321. The slide head part 422 and the central axis of the slide head part 422 coincide.

[0137] The brush also has a second assembly space, the liquid supply switching assembly 4 is installed in the second assembly space, and the first assembly space 34 communicates with the second assembly space through the through hole 343. The liquid supply switching assembly 4 is detachably installed in the second assembly space through the fixing part 43. Specifically, the fixing part 43 is provided with two fixing lugs 432 arranged diagonally, and the liquid supply switching assembly 4 is detachably fixed in the second assembly space through the two fixing lugs 432.

[0138] The elastic part 41 can be an elastic structure such as a spring, to assist the moving part 42 in linear reciprocating motion with the rotating part 321.

[0139] According to an embodiment of the moving part 42, the first liquid supply path includes a first liquid supply hose 44, and the second liquid supply path includes a second liquid supply hose 45. The slide rod part 421 of the moving part 42 is provided with a pressing column 421a, which is located between the first liquid supply hose 44 and the second liquid supply hose 45. When the pressing column 421a moves synchronously with the slide rod part 421, it presses one of the first liquid supply hose 44 and the second liquid supply hose 45, thereby closing one of the first liquid supply path and the second liquid supply path while opening the other.

[0140] It should be noted that the pressing column 421 is arranged vertically on the side wall of the slide rod part 421, the fixing part 43 is provided with a window 433 through which the pressing column 421a passes, the window 433 communicates with the slide cavity 431, and the length of the window 433 along the extension direction of the slide cavity 431 limits the movement range of the moving part 42, that is, the pressing column 421a makes linear reciprocating motion in the window 433. In this way, not only is the movement range of linear reciprocating motion limited, but also the slide rod part 421 can be prevented from falling out of the slide cavity 431.

[0141] In the first movement position, the pressing column 421a presses and closes the second liquid supply hose 45, and at this time the first liquid supply hose 44 is not pressed and is in an open state. In the second movement position, the pressing column 421a presses and closes the first liquid supply hose 44, and at this time the second liquid supply hose 45 is not pressed and is in an open state.

[0142] To ensure the closing effect of the extrusion column 421a on the first and second liquid supply passages, the liquid supply switching assembly 4 further comprises a limiting piece 46, which is provided with a passing cavity 461 for the parallel passing of the first and second liquid supply hoses 44 and 45. The extrusion column 421a extends into the passing cavity 461 through the window 433 and is located between the first and second liquid supply hoses 44 and 45 arranged side by side.

[0143] It should be noted that the passing direction of the first and second liquid supply hoses 44 and 45 in the passing cavity 46 is perpendicular to the extension direction of the sliding cavity 431, i.e., the passing direction of the first and second liquid supply hoses 44 and 45 is perpendicular to the moving direction of the moving piece 42.

[0144] The length of the passing cavity 461 along the extension direction of the sliding cavity 431 is not greater than the sum of the diameters of the first and second liquid supply hoses 44 and 45, so as to ensure the closing effect of the extrusion column 421a on the two hoses.

[0145] The limiting piece 46 is located directly above the fixed piece 43, and the passing cavity 461 is located directly above the window 433. Specifically, the limiting piece 46 is provided with a first passing-in hole 462, a second passing-in hole 463, a first passing-out hole 464 and a second passing-out hole 465, which are in communication with the passing cavity 461. The first and second passing-in holes 462 and 463 are oppositely arranged, and the first and second passing-out holes 464 and 465 are oppositely arranged. The first and second passing-in holes 462 and 463 are arranged on the same side, and the first and second passing-out holes 464 and 465 are arranged on the same side, i.e., the first liquid supply hose 44 enters the passing cavity 461 through the first passing-in hole 462 and then passes out through the first passing-out hole 464, and the second liquid supply hose 44 enters the passing cavity 461 through the second passing-in hole 463 and then passes out through the second passing-out hole 465. The bottom wall of the limiting piece 46 is provided with a limiting hole 466 in communication with the passing cavity 461. The extrusion column 421a extends into the passing cavity 461 through the limiting hole 466. The length of the limiting hole along the extension direction of the sliding cavity 431 is less than the length of the passing cavity 461 along the extension direction of the sliding cavity 431, thereby limiting the moving range of the moving piece 42.

[0146] It should be noted that the length of the extrusion column 421a extending into the passing cavity 461 is not less than any one of the diameters of the first and second liquid supply hoses 44 and 45, so as to ensure the closing effect of the extrusion column 421a on the first and second liquid supply hoses 44 and 45.

[0147] Preferably, the top wall of the limiting member 46 is also provided with a limiting hole 466 corresponding to the limiting hole 466 of the bottom wall, and the extrusion column 421a can partially extend into the limiting hole 466 of the top wall of the limiting member 46, so as to further improve the closing effect of the extrusion column 421a on the first liquid supply hose 44 and the second liquid supply hose 45.

[0148] In order to improve the stability of the liquid supply switching assembly 4, the outer wall of the limiting member 46 is provided with two fixed lugs 467 arranged at opposite angles, and the limiting member 46 is detachably fixed to the second assembly space through the two fixed lugs 467.

[0149] Preferably, the two diagonal lines of the two fixed lugs 467 and the two diagonal lines of the two fixed lugs 432 are cross-distributed, and more preferably, the two diagonal lines are perpendicular, so as to improve the assembly stability of the liquid supply switching assembly 4 as much as possible.

When the floor brush uses the second cleaning part 2 to clean the carpet, the water suction port 201 is close to the surface to be cleaned to form a relatively sealed dirt suction space, so as to suck the dirt on the carpet as much as possible.

[0154] In order to avoid the influence of the water suction bar 21 on the cleaning work of the first cleaning part 1, the floor brush comprises a lifting mechanism 5, which is operable to control the distance between the water suction port 201 and the surface to be cleaned, and further, the lifting mechanism is capable of at least controlling whether the water suction port 201 is in contact with the surface to be cleaned.

[0155] The lifting mechanism 5 comprises a first lifting position and a second lifting position.

[0157] The lifting mechanism 5 comprises a lifting button 51, which is pressed to switch between the first lifting position and the second lifting position, so as to be operated by the user.

[0158] In order to improve the cleaning effect of the first cleaning part 1, the floor brush further comprises a scraping strip 11, which is in interference contact with the surface to be cleaned when the first cleaning part 1 is cleaning. The scraping strip 11 is located directly behind the first cleaning part 1, so that the water stains or dirt on the surface to be cleaned are scraped back to the first cleaning part 1 for cleaning and recycling.

[0159] In order to avoid the influence of the scraping strip 11 on the cleaning work of the second cleaning part 2, the floor brush further comprises an adjusting mechanism 6 in transmission connection with the scraping strip 11, and the scraping strip 11 is located behind the first cleaning part 1 in the advancing direction of the floor brush for the cleaning equipment. The adjusting mechanism 7 is operable to control whether the scraping strip 11 is in contact with the surface to be cleaned, that is, the tension adjusting mechanism is operable to move the scraping strip so that the scraping strip is in contact with or separated from the surface to be cleaned.
