Figure 1 shows a schematic view of the surface cleaning apparatus from one angle. Figure 2 shows a schematic view of another angle of view of the surface cleaning apparatus. Fig. 18 shows an exploded view of a surface cleaning apparatus of the present disclosure.

As shown in fig. 1, 2, and 18, the surface cleaning apparatus may include a handle portion 100, a main body portion 200, a cleaning liquid storage portion 300, a recovery storage portion 400, a connecting portion 500, and a cleaning base 600.

The handle portion 100 may include a handle portion 110 and a connecting rod 120. The handle portion 110 is for holding by a user to operate the surface cleaning apparatus.

A control portion 111 may be provided on the handle portion 110, wherein a user may control the surface cleaning apparatus through the control portion 111, the control portion 111 may be in the form of a control button, a touch button, or the like, and a plurality of control portions 111 may be provided on the handle portion 110 to perform various controls on the surface cleaning apparatus.

The control part 111 may be disposed in a receiving space provided in the handle part 110, and in the case of a control button or the like, for example, the control part 111 may move relative to the surface of the handle part 110 to turn on or off the corresponding operation. The surface of the control portion 111 may be disposed to be recessed with respect to the outer contour surface of the handle portion 110, that is, the surface of the control portion 111 may be disposed to be lower than the outer contour surface of the handle portion 110. With such an arrangement, a user can be prevented from operating the surface cleaning apparatus by mistake or unintentionally. For example, in the case where the surface cleaning apparatus uses a cleaning liquid having a relatively high temperature, it is possible to ensure the operation related to the high-temperature cleaning liquid, and for example, in the case where the high-temperature cleaning liquid is replenished from a base station or cleaning is performed by the high-temperature cleaning liquid, if the control portion concerned is erroneously triggered, a safety hazard may be caused. For safety, a control unit in the form of a thumb switch or the like may be used.

The connecting rod 120 may be disposed between the handle portion 110 and the body portion 200 to connect the handle portion 100 and the body portion 200. Wherein the connecting rod 120 may be in the form of a hollow tube, for example it may be a hollow round tube. The connecting rod 120 may be fixedly connected to or integrally provided with the handle portion 110. The connection end of the connection rod 120 is connected to the body portion 200.

Fig. 3 shows a schematic view of the connection of the handle portion 100 with the body portion 200. As shown in fig. 3, the inside of the connection rod 120 may be provided with a connection member 123, and the connection end of the connection rod 120 may be provided with a mounting hole 121 and a mounting groove 122, the mounting groove 122 may be a notch extending along the length direction of the connection rod 120, or a groove provided at the end of the connection rod 120, and in the case where the connection rod 120 is inserted into the body portion 200, the mounting groove 122 may be engaged with a protrusion provided in the body portion 200, so that the handle portion 100 may be prevented from rotating after the connection rod 120 is connected to the body portion 200.

As shown in fig. 4, the connecting member 123 is fixed to the connecting rod 120, the connecting member 123 is formed with a first elastic part 1231 and a second elastic part 1232, and the connecting member 123 is mounted to the connecting rod 120 by the fixation of the first elastic part 1231 to the connecting rod 120; for example, the connecting member 123 is formed with a fixing hole 124, the fixing hole 124 may be positioned above the mounting hole 121, and when the connecting member 123 is inserted into the connecting rod 120, the first elastic part 1231 is positioned in the fixing hole 124 to fix the connecting member 123 with the connecting rod 120.

The second elastic portions 1232 are fitted with the mounting holes 121, and portions of the second elastic portions 1232 are positioned outside the connecting rod 120, such that when the connecting rod 120 is inserted into the body 200, the portions of the second elastic portions 1232 positioned outside the connecting rod 120 are fitted with the stopper grooves formed in the body 200, to restrict the movement and rotation of the connecting rod 120.

For example, the second elastic portion 1232 passes through the mounting hole 121 and is located in the limiting groove of the main body portion 200; when the connection rod 120 needs to be disassembled, a hole structure may be formed at the outside of the body portion 200, and the connection rod 120 may be drawn out by pressing the second elastic portion 1232 into the inside of the connection rod 120 using an object of a hardness angle through the hole structure.

Here, the first elastic portion 1231 and the second elastic portion 1232 may be formed by forming a groove in the vicinity thereof, so that the connecting member 123 may be integrally formed.

As shown in FIG. 1, surface cleaning apparatus may also include a display 214, and display 214 may be in the form of, for example, an LED or LCD display screen, a touch screen, or an indicator light. As shown in fig. 1 (only the mounting position of the display unit is shown in fig. 1), the display unit 214 may be provided on the front side surface of the main body 200, or the display unit 214 may be provided on the upper side surface of the main body 200. In the present disclosure, it is preferable that the display screen is disposed at an upper side of the main body portion 200. In addition, the present disclosure may include two or more display portions 214, and may be provided at positions such as the front side and the upper side, respectively. Display 214 may provide a display interface to display the operational status of the surface cleaning apparatus, etc. to a user. Further, in the case where the display portion 214 is a touch panel, the surface cleaning apparatus may receive an instruction of the user through the touch panel. In one embodiment, display 214 may display a plurality of poses of the surface cleaning apparatus, and may display pose information of the surface cleaning apparatus, including, but not limited to: a condition of a surface to be cleaned (hard floor, carpet, etc.), a cleaning mode (e.g., normal cleaning mode, intensive cleaning mode, pressurized cleaning mode, etc.), a battery power condition, a wireless (e.g., WIFI) connection gesture, a cleaning liquid level, a cleaning liquid storage mounted in place, a recovery liquid level, a solid liquid separator gesture, a floor type, a self-cleaning mode, etc. The gesture display type provided by the display part can be various display types such as visual display, text display, graphic display or indicator light display.

As shown in fig. 15, a power supply part 800 may be provided in the main body part 200 of the surface cleaning apparatus, and the power supply part 800 may be a battery such as a rechargeable battery, so as to implement cordless operation. The battery may be a polymer battery or a lithium ion battery, etc. And in one embodiment, the power supply part 800 may be detachably mounted to the main body part 200, and charging may be performed by detaching the power supply part 800 from the main body part 200. In addition, the power supply unit 800 may further include a charging port or a power line, and may be charged through the charging port without detaching the rechargeable battery, or may be operated by a cord through the power line, so that the cord operation may be performed when the cruising power demand is high, and the rechargeable battery may be in a power-off posture (supplied with power through the power line) when the cord operation is performed, or may be charged while supplying power to the surface cleaning apparatus.

In the present disclosure, the power supply part 800 is positioned to be isolated from potential liquid contact, for example, to avoid the influence of leakage of the cleaning liquid storage part 300 and/or the recovery storage part 400 and the like on the power supply part 800. In the present disclosure, the power supply part 800 is disposed at a position above the cleaning liquid storage part 300 and/or the recovery storage part 400 and is disposed in the main body part 200. Preferably, the power supply part may be disposed at a position below the cleaning liquid storage part 300 and/or the recovery storage part 400 and in the main body part 200, and more preferably, in the main body part 200 near the connection part 500, and by this arrangement, the position of the center of gravity of the surface cleaning apparatus may be effectively lowered, thereby relieving the hand pressure of the user. Of course, it will be understood by those skilled in the art that other locations are possible, and it is only necessary to maintain the power supply part 800 at a spaced distance from the location where the liquid leakage may occur.

In the present disclosure, as shown in fig. 5, the various components of the surface cleaning apparatus are arranged relative to each other so that the surface cleaning apparatus can be rotated in two directions (a first direction and a second direction). Although it is shown in the present disclosure that the rotation may be in two directions, it may be set by those skilled in the art to rotate only in the first direction described below.

Wherein the first direction is in a plane perpendicular to the surface to be cleaned, which may also be referred to as up-and-down rotation with respect to the surface to be cleaned, the first direction being defined by the X-axis in fig. 5; this second direction, which is defined in fig. 5 by the Y-axis, is in a plane parallel to the surface to be cleaned and may also be referred to as a side-to-side rotation relative to the surface to be cleaned.

As shown in fig. 6, the rotation of the surface cleaning apparatus may be defined by the attachment 500 described above. Wherein the connection part 500 may be a separate component and fixed to the lower end of the main body part 200, or the connection part 500 may be a component integrally molded with the main body part 200 and located at the lower end of the main body part 200.

The connection part 500 is used to connect the main body part 200 with the cleaning base 600, the connection part 500 may be a hollow structure, and air, fluid communication, and lines and the like required for power supply and the like between the main body part 200 and the cleaning base 600 such as a floor brush may be implemented through the connection part 500, so that power supply, circulation of air and/or liquid, and the like may be implemented between the main body part 200 and the cleaning base 600 via wires and/or pipes passing through the connection part 500. Furthermore, a flexible hose for sucking dust and recovering liquid may be passed through the connection portion.

A recovery hose 506 for recovering liquid, garbage, and the like may be accommodated in the connection part 500, an outlet of the recovery hose 506 may communicate with the recovery storage part 400, and a position of the recovery hose 506 with respect to the connection part 500 is preferably fixed so that the recovery hose 506 is firmly and hermetically connected to the recovery conduit 414 of the recovery storage part 400.

The recovery hose 506 is flexible and may be deformed in response to the inclination of the surface cleaning apparatus. In addition, a cleaning liquid supply line 308 may be received inside the connection part 500, and the cleaning liquid supply line 308 may pass through the connection part 500 and communicate with a corresponding line in the cleaning base 600, thereby sending the cleaning liquid into the cleaning base 600. The cleaning liquid supply conduit 308 may be rigid and not bend as the connection rotates. Further, a liquid detecting device may be further provided at the cleaning liquid supply line 308 for detecting whether the cleaning liquid is supplied to the cleaning base 600, and a detection signal of the liquid detecting device may be supplied to a microprocessor or the like.

According to one embodiment, the connection part 500 may include a universal joint to enable the main body part 200 to be rotated in both directions with respect to the cleaning base 600.

According to one embodiment, the connection part 500 may include a polyaxial joint that may couple the main body part 200 with the cleaning base 600 so as to allow the main body part 200 to rotate in the first direction and the second direction with respect to the cleaning base 600.

As shown in fig. 6, the main body 200 can be pivoted to an upright position (also referred to as a storage position) by the link 500, in which the angle between the main body 200 and the surface of the cleaning base 600 (or the floor surface on which it is placed) is 80 ° to 90 °, preferably around 80 °. In this position, the surface cleaning apparatus is in a self-supporting attitude (also referred to as an upright attitude), that is, the main body portion 200 and the like can be supported by the cleaning base 600, and the upright attitude can be achieved without the aid of other objects.

The connection portion 500 may be provided with a stopper protrusion 504. The stopper protrusion 504 may be provided at a rear position of the connection part 500, and it may be integrally formed with the connection part 500. The limit protrusion 504 protrudes with respect to the surface of the connection part 500, and the limit protrusion 504 may include at least a limit plane 505. The stopper planes 505 may be provided at positions on both sides of the connection part 500. Accordingly, the cleaning base 600 can include an outwardly extending mount 6611. In the present disclosure, the mounts 6611 are two in number and each extend outwardly from the cleaning base 600. The mount 6611 may be used to support the two moving wheels 662. A roller, such as the moving wheel 662, may be secured to the mount 6611. The two mounting members 6611 are spaced apart by a predetermined distance, wherein the distance may be equal to or slightly greater than the distance between the two limiting planes 505, such that when the main body portion 200 is rotated within a predetermined angular range (e.g., 0 ° to 30 °), the two limiting planes 505 may respectively contact the inner wall surfaces of the two mounting members 6611, thereby limiting the rotation of the main body portion in the Y direction. It should be noted that the mounting member 6611 should not impose any restriction on the rotation of the main body portion 200 without being within the predetermined angular range.

Further, at least one of the two mounting members 6611 may be provided as a hollow structure through which electric wires and/or pipes may be allowed to pass so as to communicate the main body portion 200 with the cleaning base 600.

According to the technical solution of the present disclosure, when the user operates the surface cleaning apparatus in a wide space, since the angle between the main body portion 200 and the surface to be cleaned is not too small (for example, in the case of 30 ° or more), since the mounting member 6611 does not have any influence on the rotation in the Y direction, the user can rotate the main body portion 200 in the Y direction, thereby guiding the cleaning base portion 600 to turn left and right (Y direction). However, when a user desires to operate the surface cleaning apparatus in a narrow or low space (e.g., a sofa bottom or the like), the surface cleaning apparatus cannot enter the narrow or low space without lowering the posture of the main body portion 200, and thus the space will not be cleaned. In the present disclosure, the user may adjust the main body portion 200 to make its posture lower, which enables the main body portion 200 to extend into a narrow or low space. When the attitude of the main body 200 is below the predetermined angle, the user's ability to control the surface cleaning apparatus starts to decline, at which time the Y-direction rotation of the main body 200 relative to the cleaning base 600 is not desired. In this way, the rotation in the Y direction can be restricted by the two stopper planes 505 contacting the inner wall surfaces of the two mounting members 6611, respectively, so that the user cannot perform the left-right guiding.

Further, although not shown in the figures, a pivot portion (e.g., a circular pivot shaft) may be provided on an inner wall surface of the mounting member 6611, and the pivot portion may be rotatably connected to the connecting portion (e.g., connected to a wall surface of the connecting portion, or provided with a corresponding lug on the connecting portion and connected to the pivot portion). Further, the inner wall surfaces of the mounting pieces 6611 on the opposite sides may be provided with pivot portions to connect with the connecting portions. By means of the pivot, the surface cleaning apparatus can be made to be rotatable in the X-direction.

In the present disclosure, when the surface cleaning apparatus is in an inclined use position (for example, in the case where the angle to the surface to be cleaned is greater than or equal to 30 °), the rotation angle in the Y direction may be defined, thereby preventing the rotation angle in the Y direction from being excessively large.

Further, the connection part 500 may be detachably mounted with the cleaning base 600. For example, a snap structure may be provided therebetween, such as a mounting hole provided on the connecting portion and a snap projection provided on the cleaning base, the engagement of the two being achieved by fitting the snap projection into the mounting hole, and the disengagement of the two being achieved by pressing the snap projection away from the mounting hole.

In the present disclosure, when the main body 200 is in the "lying flat" (parallel to the surface to be cleaned) posture, the height of the main body 200 is set to 120mm or less, for example, the height may be set to 100mm to 120mm, or 105mm to 120mm, or the like, and further, the height of the cleaning base 600 is set to be less than or equal to the height of the main body 200. In addition, the width of the cleaning base 600 should be set to be greater than or equal to the width of the main body 200 (the "width" referred to herein means the width of the cleaning base and the main body in a direction perpendicular to the direction of travel of the surface cleaning apparatus (both directions are in a horizontal plane)).

In addition to facilitating movement of the surface cleaning apparatus by a user when the main body 200 is in a "lie flat" (parallel to the surface to be cleaned) position, parallel rollers 215 may also be provided. In the lying position shown in fig. 6, the user can operate the surface cleaning apparatus by holding the handle portion without providing a supporting force to the surface cleaning apparatus, according to the parallel roller 215. The supporting force of the surface cleaning apparatus can be achieved by moving the wheels and the parallel rollers. Thus in the lying position, the user need only apply a towing force to operate the surface cleaning apparatus. In addition, the parallel roller 215 is disposed at a position separated from the center of gravity of the surface cleaning apparatus or the center of gravity of the main body to prevent the surface cleaning apparatus from being tilted. The parallel roller may be provided on the main body portion, on the handle portion, or the like.

According to the above-mentioned embodiment of the present disclosure, the user can make the main body part rotate along both the X direction and the Y direction within a certain angle range, and can conveniently realize the guidance of the cleaning base part, and the main body part will be restricted from rotating in the Y direction within another angle range. This arrangement may allow the user to better operate the surface cleaning apparatus.

As shown in fig. 15, the main body 200 may include a frame body 220 for supporting the cleaning liquid storage 300 and the recovery storage 400, and may also be used for supporting other components, such as a motor, a fan, and the like. For example, on a portion of the frame body 220 that houses the cleaning liquid storage 300 and the recovery storage 400, two housing walls may be provided, and the liquid storage 300 and the recovery storage 400 are housed at least partially in the two housing walls, which may constitute a housing of the surface cleaning apparatus. In the case of two accommodation walls, the accommodation walls are provided on opposite sides of the side of the surface cleaning apparatus different from the cleaning liquid storage part 300 and the recovery storage part 400, and extend in the height direction of the surface cleaning apparatus.

The cleaning liquid storage part 300 and the recovery storage part 400 may be disposed on the frame body 220 so as to be located at both sides of the main body part 200.

In order to form the first chamber 412 as a sealed chamber, a seal member is provided at a circumferential position of the top wall 4311, and such that the seal member is located between the top wall 4311 and an inner side wall of the first chamber 412 of the case portion 410, thereby causing the first chamber 412 to be sealed.

More preferably, the top wall 4311 is located below the through hole 415 of the tank portion 410 and is disposed at a position that does not affect the gas-liquid separator 422.

The bottom wall 4312 is fixed to the top wall 4311, and preferably, a liquid guiding hole is opened on the bottom wall 4312, so that the recovered liquid flows out from the solid storage part 431 to the cavity of the recovery storage part 400, and only the solid garbage is left. Wherein the drain hole is sized to allow only liquid or liquid and fine debris to pass through. The solid storage part 431 may further include an open part so that the solid waste can be discharged through the open part when the user cleans the solid waste. A conduit pass-through 432 may be provided in the bottom wall 4312, the conduit pass-through 432 allowing the recovery conduit 414 to pass therethrough, wherein the recovery conduit 414 communicates with the inlet of the recovery storage 400 to direct recovered liquid or solids or the like into the recovery storage when the surface cleaning apparatus is in operation. Preferably, the conduit passing portion 432 is formed integrally with the bottom wall 4312, and of course, the conduit passing portion 432 may be formed separately from the bottom wall 4312.

The bottom wall 4312 is formed into a porous structure, and the above-described liquid-conducting hole is formed through the porous structure, so that the bottom wall 4312 is formed into a filter member; accordingly, to enable the solid waste stored on the bottom wall 4312 to be moved out of the box portion 410 as the solid-liquid separator 430 is moved out of the box portion 410, a flange portion 4313 may be provided on the bottom wall 4312, for example, the flange portion 4313 may be at least partially disposed around the bottom wall 4312, and the solid waste may be stored in an area surrounded by the flange portion 4313.

One end of the suction pipe portion 433 is located below the bottom wall, and the other end of the suction pipe portion 433 is located above the top wall 4311, so that when the gas-liquid separation apparatus is operated, the liquid filtered by the bottom wall 4312 is sucked from the inside of the first chamber 412 to the outside of the first chamber 412.

Specifically, the upper end of the suction pipe portion 433 may be fixed to the top wall 4311, for example, the suction pipe portion may be integrally formed with the top wall 4311, but the suction pipe portion 433 may be formed separately from the suction pipe portion 433 and fixed to the top wall 4311.

The lower end of the suction pipe portion 433 penetrates through the bottom wall 4312 and is located below the bottom wall 4312, in this case, a through hole for the suction pipe portion 433 to penetrate through may be formed on the bottom wall 4312 so as to facilitate the suction pipe portion 433 to penetrate through the bottom wall 4312, and when the solid-liquid separator 430 is disposed in the case portion 410, the lower end of the suction pipe portion 433 may contact with the bottom wall of the first chamber 412 so as to reduce the liquid in the first chamber 412 as much as possible.

Further, in view of the surface cleaning apparatus being rotatable in the second direction, as shown in fig. 12, the number of the suction pipe portions 433 may be set to two, and the two suction pipe portions 433 may be located on both sides of the conduit passing portion 432 of the bottom wall 4312; that is, the two suction pipe portions 433 may be located near the rear sidewall of the first chamber 412, for example, at two corners of the first chamber 412, so that when the surface cleaning apparatus is rotated to a certain position in the second direction, the liquid is collected toward the corners of the first chamber 412, and then the liquid may be sucked to the outside of the first chamber 412 through the suction pipe portions 433 located at the corners.
