A power supply 800, which may be a battery such as a rechargeable battery, may be provided in the main body portion 200 of the surface cleaning apparatus in order to achieve 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 body part 200, and charging may be performed by removing the power supply part 800 from the body part 200. In addition, the power supply part 800 may further be provided with a charging port or a power cord, and may be configured to charge the rechargeable battery without detaching the rechargeable battery, or may be configured to perform a corded operation through the power cord, so that the corded operation may be performed in a high-endurance condition, and the rechargeable battery may be in a power-off state (powered through the power cord) in the corded operation, or may be charged while powering the surface cleaning apparatus.

In the present disclosure, the power supply 800 is positioned to be isolated from potential liquid contact, e.g., to avoid leakage of the cleaning liquid storage 300 and/or the recovery storage 400, etc., from affecting the power supply 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 in the main body part 200. Preferably, the power supply part may be provided at a position below the cleaning liquid storage part 300 and/or the recovery storage part 400 and in the main body part 200, more preferably, in the main body part 200 near the connection part 500, by which the gravity center position of the surface cleaning apparatus may be effectively lowered, thereby reducing the hand pressure of the user. Of course, those skilled in the art will appreciate that other locations are possible, and that only the power supply 800 need be maintained at a spaced distance from the location where liquid leakage may occur.

In the present disclosure, 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. Although it is shown in the present disclosure that it is movable in two directions, a person skilled in the art may set it to move only in the first direction described below.

In which a rotation of the surface cleaning apparatus in a first direction (hereinafter also referred to as X-direction) is shown in fig. 5 to 7, 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 relative to the surface to be cleaned. For example, fig. 5 shows the surface cleaning apparatus in an upright posture, fig. 6 shows the surface cleaning apparatus in a posture rotated by 30 °, and fig. 7 shows the surface cleaning apparatus rotated to a posture parallel to the surface to be cleaned. Wherein in the first direction, the surface cleaning apparatus (main body portion) is capable of rotating in a range of 0 ° to 120 °, optionally in a range of 0 ° to 95 °, 0 ° to 110 °, etc., with respect to the surface to be cleaned. The posture parallel to the surface to be cleaned means that the angle between the main body portion and the surface to be cleaned is 0 ° or substantially 0 ° (e.g., 0 ° to 5 °, etc.).

Fig. 8 to 10 show a rotation of the surface cleaning apparatus in a second direction (hereinafter also referred to as Y-direction), which is in a plane parallel to the surface to be cleaned, which may also be referred to as left-right rotation with respect to the surface to be cleaned. For example, fig. 8 shows a surface cleaning apparatus that is not rotated in the second direction, fig. 9 shows a surface cleaning apparatus that is rotated in the second direction, and fig. 10 shows a surface cleaning apparatus that is not rotated in the second direction.

As shown in fig. 6, the X axis about which the X direction rotates may be perpendicular to the plane of the paper of fig. 6, and the X direction rotation may be defined by a pivot joint. The Y axis about which the Y-direction rotates may be perpendicular to the X axis (a direction parallel to the plane of the paper of fig. 6, e.g. the Y axis extends along the main body portion), and the Y-direction rotation may be defined by a swivel joint, further the Y axis may optionally be perpendicular to the axis of the moving wheel of the cleaning base and/or the axis of the roller brush of the cleaning base. The Y-axis may be at an angle (e.g. an acute angle) to the rest surface of the surface cleaning apparatus, for example 80 ° to 90 °, preferably around 80 °, when the main body is in an upright position, as shown in fig. 5, the acute angle being the angle between the main body and the cleaning base, that is, the main body is inclined in a forward (left "in fig. 5) downward direction. When the main body is turned, the surface cleaning apparatus is brought into an inclined use position such that the Y-axis will be at an acute angle to the rest surface (surface to be cleaned) on the other side (right side), that is, the main body is inclined in a rearward (right in fig. 5) downward direction.

When the surface cleaning apparatus is in the tilted use posture, the X axis is set to be in a position where the intersection of the Y axis and the surface to be cleaned is rearward (rightward in the drawing) as viewed from the position where the user is using the surface cleaning apparatus, as shown in fig. 5 and 6, when the surface cleaning apparatus is in the upright posture.

The rotation of the surface cleaning apparatus may be defined by the connection 500 described above. Wherein the connection part 500 may be a separate member and fixed to the lower end of the body part 200, or the connection part 500 may be a member integrally formed with the body part 200 and located at the lower end of the body part 200.

The connection part 500 is used to connect the main body part 200 with the cleaning base part 600, the connection part 500 may be a hollow structure, and all of air, fluid communication, and lines required for power supply, etc. between the main body part 200 and the cleaning base part 600 such as a floor brush may be realized by the connection part 500, so that power supply, communication of air and/or liquid, etc. may be realized between the main body part 200 and the cleaning base part 600 via wiring and/or piping through the connection part 500. Furthermore, a flexible hose for sucking and recovering liquid may pass through the connection part.

As shown in fig. 11, a recovery hose for recovering liquid, garbage, and the like can be accommodated in the connection portion 500, and an outlet 506 of the hose can communicate with the recovery storage portion. The recovery hose is flexible and can be deformed according to the inclination of the surface cleaning apparatus. In addition, a cleaning liquid supply line 308 may be accommodated, and the cleaning liquid supply line 308 may pass through the connection part 500 and communicate with a corresponding line in the cleaning base part 600, thereby delivering the cleaning liquid into the cleaning base part 600. The cleaning liquid supply line 308 may be rigid and does not bend as the connection rotates. A liquid detection 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 detection 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 rotate in two directions with respect to the cleaning base part 600.

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

As shown in fig. 5, the main body 200 can be pivoted by the connection part 500 to an upright position (which may also be a storage position) in which an angle between the main body 200 and a surface of the cleaning base 600 (or a placement floor) is 80 ° to 90 °, preferably around 80 °. In this position, the surface cleaning apparatus is in a self-supporting posture (also referred to as an upright posture), that is, the main body portion 200 and the like can be supported by the cleaning base portion 600, and the upright posture can be achieved without resort to other objects.

When the rotation in the X direction is defined by the pivot joint, for example, as shown in fig. 5, the surface of the cleaning base 600 may be provided with a supporting boss 501, and correspondingly, the connection portion 500 may be provided with a supporting fitting portion 502 (as shown in fig. 6). As shown in fig. 8, the support boss 501 may be formed with a support groove 503, and the support groove 503 is provided corresponding to the support fitting portion 502 so that when the main body portion 200 is caused to be in an upright position (for example, between 80 ° and 90 ° with respect to the forward direction), the support fitting portion 502 is fitted into the support groove 503, and since the cleaning base 600 is placed on the floor, it may form a seat, and since the support fitting portion 502 abuts against the support boss 501, the surface cleaning apparatus is caused to be in a self-supporting posture. Wherein the support engaging portion 502 and the support projecting portion 501 also have a releasable locking effect, and are engaged when the main body portion is brought to the upright position. When pivoting from the upright position to the main body portion, the user may apply a force such that the two are disengaged.

When the main body 200 is rotated in the X direction, the support fitting portion 502 and the support boss 501 can be disengaged, for example, as shown in fig. 6. After the support fitting portion 502 and the support boss 501 are detachable, the main body 200 can be rotated in the Y direction until a predetermined angle by which the main body 200 can be rotated. For example, fig. 8 shows the body 200 rotated to an angle at which the body 200 is rotated in the Y direction, and fig. 9 shows the body 200 rotated. Here, the predetermined angle may be an angle forming an angle of 30 ° with the horizontal direction of the surface to be cleaned. Of course, other angles, such as about 20, etc., may be provided.

As shown in fig. 7, the main body portion 200 can be finally rotated in the X direction to a position horizontal to the surface to be cleaned, and in the case of being smaller than the above predetermined angle (for example, in the case of being smaller than 30 °). The main body 200 may be prevented from rotating in the Y direction with respect to the cleaning base 600.

The connection portion 500 may be provided with a limit protrusion 504. The limit protrusion 504 may be provided on one side of the connection part 500 opposite to the support fitting part 502, and it may be integrally formed with the connection part 500. The limit projection 504 protrudes with respect to the surface of the connection part 500, and the limit projection 504 may include at least a limit flat surface 505. The limiting planes 505 may be disposed at positions on both sides of the connection part 500. Accordingly, the cleaning base 600 can include outwardly extending mounts 6611. In the present disclosure, the number of the mounting pieces 6611 is two, and extends outwardly from the cleaning base 600, respectively. The mount 6611 may be used to support two moving wheels. For example, the roller of the moving wheel may be fixed to the extension arm. 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 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 in the Y direction. It should be noted that, in the case where the predetermined angle range is not present, the mount 6611 should not cause any restriction in rotation of the main body 200.

Furthermore, at least one of the two extension arms may be provided as a hollow structure through which wires and/or lines may be allowed to pass in order to communicate the main body portion with the cleaning base portion.

According to the technical scheme of the present disclosure, when the user operates the surface cleaning apparatus in a wide space, since the angle between the main body part 200 and the surface to be cleaned is not too small (for example, 30 ° or more), since the mount 6611 does not have any influence on the rotation in the Y direction, the user can rotate the main body part 200 in the Y direction, thereby guiding the cleaning base 600 to turn left and right (Y direction). However, when a user needs to operate the surface cleaning apparatus in a narrow or low space (e.g., a sofa bottom, etc.), 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 body portion 200 to have a lower posture, which enables the body portion 200 to extend into a narrow or low space. When the posture of the main body 200 is lower than a predetermined angle, the user's control ability of the surface cleaning apparatus starts to decline, at which time Y-direction rotation of the main body 200 with respect to the cleaning base 600 is not desired. In this way, the rotation in the Y direction can be restricted by the two restricting planes 505 coming into contact with the inner wall surfaces of the two mounting pieces 6611, respectively, so that the user cannot conduct the left-right guidance.

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

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

Further, the connection part 500 may be detachably installed with the cleaning base part 600. For example, a snap structure may be provided therebetween, such as a mounting hole provided on the connection portion, and a snap protrusion provided on the cleaning base portion, the coupling of the two being achieved by fitting the snap protrusion to the mounting hole, and the separation of the two being achieved by pressing such that the snap protrusion is away from the mounting hole.

In the present disclosure, as shown in fig. 7, when the main body part 200 is in a "lying-down" (parallel to the surface to be cleaned) posture, the height of the main body part 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 part 600 is set to be less than or equal to the height of the main body part 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 refers to the width of the cleaning base and the main body in a direction perpendicular to the traveling direction of the surface cleaning apparatus (both directions are in horizontal planes).

In addition, parallel rollers 215 may be provided to facilitate movement of the surface cleaning apparatus by a user when the main body portion 200 is in a "lying" position (parallel to the surface to be cleaned). In the lying posture as shown in fig. 7, according to the parallel roller 215, the user can operate the surface cleaning apparatus by holding the handle portion without providing a supporting force to the surface cleaning apparatus. The supporting force of the surface cleaning apparatus can be achieved by moving the wheel and the parallel roller. 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 portion, so as to prevent the surface cleaning apparatus from tilting. The parallel roller may be provided on the main body portion, or may be provided on the handle portion, or the like.

According to the above-described embodiments of the present disclosure, the user can make the main body portion rotatable in both the X-direction and the Y-direction within a certain angular range, and can conveniently realize the guiding of the cleaning base portion, and the main body portion will be restricted from rotating in the Y-direction within another angular range. This arrangement may allow a user to better operate the surface cleaning apparatus.

As shown in fig. 3, the main body part 200 may include a frame body 220 for supporting the cleaning liquid storage part 300 and the recovery storage part 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 where the cleaning liquid storage part 300 and the recovery storage part 400 are accommodated, two accommodation walls may be provided, and the liquid storage part 300 and the recovery storage part 400 are at least partially accommodated in the two accommodation 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 provided on the frame body 220 so as to be located at both sides of the main body part 200. In the present disclosure, the optional cleaning liquid storage part 300 and the recovery storage part 400 are located at both left and right sides (with respect to the traveling direction of the surface cleaning apparatus, cleaning path) of the main body part 200. The thickness of the cleaning liquid storage part 300 may be equal to or less than the thickness of the recovery storage part 400, and the heights thereof may be the same or substantially the same. Although the cleaning liquid storage part 300 and the recovery storage part 400 are mainly described as being located on both sides of the main body part 200 in the present disclosure, it is also preferable in the present disclosure that the cleaning liquid storage part 300 and the recovery storage part 400 are provided on both front and rear sides (both front and rear sides along the cleaning direction) of the main body part 200, and in the case of being provided on both front and rear sides, the respective arrangement relationships of the respective components described herein are the same or similar.

In the present disclosure, the cleaning liquid storage part 300 and the recovery storage part 400 may be detachably mounted to the side of the frame body 220, the mounted sides may be opposite sides of the frame body 220, and the thickness of the cleaning liquid storage part 300 and the recovery storage part 400 is set to be smaller than the width, so that a sufficient capacity can be secured and the body part 200 can be made to lie flat with a height smaller than a predetermined height, for example, 120mm.

A schematic diagram of a cleaning liquid storage 300 according to one embodiment of the present disclosure is shown in fig. 12 and 13. Fig. 14 shows a schematic view of the cleaning liquid storage section 300 with a portion of the wall removed. The cleaning liquid storage part 300 is used to store the cleaning liquid and is provided to the cleaning base 600 via a pipe. Herein, the cleaning liquid may be one or more of any suitable liquid including, but not limited to, cleaning water, concentrated detergent, diluted detergent, or mixtures thereof, and the like. The cleaning liquid may be a normal temperature cleaning liquid or a high temperature cleaning liquid.

As shown in fig. 12 to 14, the cleaning liquid storage part 300 has a flat shape and includes a cavity constituted by a plurality of wall surfaces so as to contain the cleaning liquid, and the capacity of the cleaning liquid storage part 300 may be set to 500mL or the like. The cleaning liquid storage part 300 may include a handle 301 and a pressing part 302, and it is preferable that the handle 301 and the pressing part 302 are located at an upper side position of the cleaning liquid storage part 300. The user can mount or take out the cleaning liquid storage section 300 through the handle 301, specifically, the user can disengage the latch 303 from the groove provided in the main body section by pinching the pressing section 302 (with a spring built in) so as to take out the cleaning liquid storage section 300. In the present disclosure, although the handle 301 is shown as an in-line handle (hidden handle), one skilled in the art may also provide it as an outwardly protruding handle. As shown in the drawing, the surface of the upper wall of the cleaning liquid storage section 300 is provided as an inclined surface, so that the cleaning liquid storage section 300 can be pushed onto the main body section 200 and fixed to the main body section 200 by the action of the latch 303 when the cleaning liquid storage section 300 is mounted.

The cleaning liquid storage part 300 may be provided with a liquid inlet 305, and the liquid inlet 305 may be closed by a cover plate 304. Thus, when the cleaning liquid is supplied to the cleaning liquid storage section 300, the cover plate 304 can be opened to input the cleaning liquid through the liquid inlet 305. The cover plate 304 may then be closed to block the liquid inlet 305, thereby avoiding leakage of cleaning liquid when the surface cleaning apparatus is in use. The cover plate 304 may pivot with respect to the wall surface of the cleaning liquid storage part 300, for example, the underside of the cover plate 304 may have a pivot shaft and the pivot shaft is inserted into the wall surface.

The cover plate 304 is further provided with a blocking portion, such as a plunger, corresponding to the liquid inlet 305, so that the liquid inlet 305 is blocked by the blocking portion when changing closure, at least partially into the liquid inlet 305. Of course, those skilled in the art will appreciate that other forms of sealing may be employed.

A vent valve, which may be a two-way vent valve, may be provided at or near the location of the liquid inlet 305 for selectively drawing gas into the cleaning liquid storage portion 300 or exhausting gas from the cleaning liquid storage portion 300 so as to equalize the internal and external pressures of the cleaning liquid storage portion 300. Further, a vent valve may be provided at an upper wall of the cleaning liquid storage part 300, and may be spaced apart from the liquid inlet 305 by a predetermined distance. The liquid inlet 305 and vent valve may be covered when the cover plate 304 is closed. When the gas pressure at two sides of the two-way ventilation valve is unbalanced, the ventilation valve can be deformed instantaneously, so that the internal and external gas circulation achieves the internal and external pressure balance.

According to one embodiment of the present disclosure, the cleaning liquid storage part 300 may further include a filter 306, the filter 306 being disposed at a liquid outlet of the cleaning liquid storage part 300, the cleaning liquid supplied to the outside of the cleaning liquid storage part 300 being filtered through the filter 306 to filter out impurities in the cleaning liquid. An outlet valve 307 may also be provided in connection with the liquid outlet to selectively allow the cleaning liquid to flow out of the liquid outlet. The outlet valve 307 may be opened to allow the cleaning liquid to be supplied when the cleaning liquid storage part 300 is mounted to the main body part 200, and the outlet valve 307 may be closed to prevent the cleaning liquid from leaking when the cleaning liquid storage part 300 is removed from the main body part 200. A filter 306 may be installed on one side of the lower wall surface of the cleaning liquid storage part 300 and an outlet valve 307 may be installed on the other side, and the installation positions of both are positions of the liquid outlet.

The outlet valve 307 may communicate with the cleaning liquid supply line 308, and the cleaning liquid supply line 308 may be accommodated inside the connection part 500 as described above and communicate with the supply line of the cleaning base 600. A liquid detecting device may be further provided near the cleaning liquid supply line 308 or the outlet valve 307 for detecting whether or not the cleaning liquid is supplied to the cleaning base 600. The liquid detection means may be any suitable detection means for detecting the presence of cleaning liquid in the cleaning liquid supply line 308. The liquid detection means may be a conductivity sensor and is located in the cleaning liquid supply line 308 to detect the presence of cleaning liquid.

When the liquid detection means detects the absence of liquid, indicating the absence of cleaning liquid in the cleaning liquid storage portion 300 or the removal of the cleaning liquid storage portion 300, the liquid detection means may provide a signal to the microcontroller, which may provide information to the user via the display portion. In addition, the liquid detection device may also be located inside the cleaning liquid storage part 300 for detecting the liquid level of the cleaning liquid storage part 300, so that when the liquid level is too low, indicating that no cleaning liquid is present in the cleaning liquid storage part 300, a signal may be provided to the micro controller, or when the cleaning liquid storage part 300 is removed from the main body part 200, the electrical connection of the liquid detection device is disconnected, and the micro controller may also know that the cleaning liquid storage part 300 is removed.

The input from the liquid detection device may further be used by the microcontroller to determine the proper shut down or otherwise interrupt the supply of cleaning liquid. The microcontroller may shut down or prevent at least one electrical element of the surface cleaning apparatus from being activated, for example, when cleaning liquid is not present in the cleaning liquid storage portion 300 or is removed. The electrical components may include pumps, valves, various motors, etc., which may stop the operation of the surface cleaning apparatus.

When the surface cleaning apparatus is in the lying posture, the height of the cleaning liquid storage part 300 may be set to be significantly larger than the width thereof, and the liquid outlet of the cleaning liquid storage part 300 may be disposed at a lower position (right position of fig. 14) of the lower wall surface of the cleaning liquid storage part 300.

Fig. 15 to 18 illustrate schematic diagrams of the reclamation store 400 according to one embodiment of the present disclosure. Wherein fig. 15 shows a schematic view of the recovery storage 400 at one angle, fig. 16 shows a schematic view of the recovery storage 400 at another angle, fig. 17 shows an exploded view of a portion of the recovery storage 400, and fig. 18 shows an exploded view of the recovery storage 400.

As shown in fig. 15 to 18, the recovery storage section 400 includes a cavity constituted by a plurality of wall surfaces so as to accommodate the recovery liquid. The recovery storage part 400 may include a second handle 401 and a second pressing part 402, and it is preferable that the second handle 401 and the second pressing part 402 are located at an upper side position of the recovery storage part 400. The user can mount or take out the recovery storage section 400 through the second handle 401, specifically, the user can disengage the second latch 403 from the groove provided in the main body section by pinching the second pressing section 402 (with a spring built in) so as to move it downward, whereby the recovery storage section 400 can be taken out. In the present disclosure, although the second handle 301 is shown as an outwardly protruding handle, it may be provided as an in-line handle (hidden handle) by those skilled in the art. As shown in the drawing, the surface of the upper wall of the recovery storage section 400 is provided as an inclined surface, so that the recovery storage section 400 can be pushed onto the main body section 200 and fixed to the main body section 200 by the action of the second latch 403 when the recovery storage section 400 is mounted.

The underside of the recovery storage 400 may be provided with an inlet 404, which inlet 404 may communicate with the outlet 506 of the hose in order to pass the recovered solid waste or recovered liquid into the recovery storage 400 through the inlet 404.

Further, a liquid level detecting portion 405 may be provided in the recovery storage portion 400, wherein the liquid level detecting portion 405 may be provided in plural so as to detect the liquid level of the internal recovery liquid both when the recovery storage portion 400 is in the upright posture and when the recovery storage portion 400 is in the horizontal posture, which will be described later in detail.

According to one embodiment of the present disclosure, the reclamation store 400 may include two parts: a first storage unit 406 and a second storage unit 407. Wherein the first storage portion 406 and the second storage portion 407 are separable. When it is necessary to remove the garbage from the recovery storage section 400 and to remove the recovery liquid, the first storage section 406 and the second storage section 407 may be separated. When the first storage part 406 and the second storage part 407 are combined together, a sealing member may be provided therebetween to ensure that the recovered liquid does not leak or the like.

As shown in fig. 17 and 18, the top wall of the first storage part 406 may be provided with a vent 408, which vent 408 provides a passage opening for gas during suction of the surface cleaning apparatus to escape from the surface cleaning apparatus. A gas filter assembly, such as a HEPA filter, may also be provided outside of the vent 408. The gas filter assembly may be disposed in the first storage portion 406 or in the body portion 200 above the first storage portion 406. For example, in the case where a gas filter assembly is provided in the body portion 200, the gas filter assembly may be provided near the gas outlet 408, receiving gas from the gas outlet 408. For example, a filter assembly receiving portion may be provided at a corresponding position of the body portion 200, and a gas filter assembly may be detachably mounted into the filter assembly receiving portion.

The gas filter assembly may include a filter media supported on a support, which in one embodiment may be pleated filter media, and may be made of a material that remains porous when wet. The gas filter assembly may further comprise a mesh screen carried by the support and disposed on the gas upstream side of the filter media for filtering large particulate matter. The gas filter assembly may be designed as a one-piece assembly for removal from the filter assembly receiver, replacement, etc.

A gas-liquid separation device 420 may be accommodated in the first storage part 406, wherein the gas-liquid separation device 420 may include a gas-liquid separation motor 421 and a gas-liquid separator 422. The gas-liquid separator 422 is operated by the rotation of the gas-liquid separation motor 421 so that the recovered gas and liquid are separated from each other, so that the liquid remains in the recovery storage section 400, and the gas is discharged from the surface cleaning apparatus after being filtered.

In one embodiment of the present disclosure, the rotation shaft of the gas-liquid separation motor 421 may be coupled with the first timing pulley 423, and the second timing pulley 424 is coupled with the first timing pulley 423 through the timing belt 425, such that the second timing pulley 424 rotates accordingly when the gas-liquid separation motor 421 rotates. The second timing pulley 424 and the bearing 426 are coupled to a drive shaft 427, and the drive shaft 427 is configured to drive the gas-liquid separator 422 to rotate.

In one embodiment, the reclamation store 400 may also include a filter 430. The filter 430 will be described in detail with reference to fig. 19 to 21, wherein the relative arrangement of the filter 430 and the gas-liquid separation device 420 is shown in fig. 20 and 21. The filter 430 may include a solids storage portion 431, a conduit passing port 432, a filtering portion 433, a second anti-surge portion 434, and a first anti-surge portion 435.

The solid storage 431 may be used to store solid waste, such as debris, hair, etc., recovered during cleaning. The solid storage portion 431 at least includes a bottom wall 4311, a first side wall 4312 and a top wall 4313, wherein liquid guiding holes are formed on the bottom wall 4311 and the first side wall 4312, so that the recycled liquid flows out from the solid storage portion 431 into the cavity of the recycling storage portion 400, and only solid garbage remains. Wherein the size of the liquid guiding holes is designed to allow only liquid or liquid and fine debris to pass through. The solid storage 431 may also include an open portion such that solid waste may be poured out through the open portion when a user cleans the solid waste. A conduit through opening 432 may be provided in the bottom wall 4311, which conduit through opening 432 allows a recovery conduit (not shown in the figures) to pass through, wherein the recovery conduit communicates with the inlet opening 404 of the liquid storage section 400 for guiding recovered liquid or solids etc. into the filter 430 when the surface cleaning apparatus is in operation.

In addition, the solid storage 431 may further include a second side wall 4314 and a third side wall 4315, wherein the second side wall 4314 and the third side wall 4315 are disposed opposite and extend between the bottom wall 4311 and the top wall 4313. In the present disclosure, the second side wall 4314 and the third side wall 4315 are provided only at a partial position between the bottom wall 4311 and the top wall 4313, and an unset position may be the above-described open portion. The solid storage part 431 may further include a fourth side wall 4316, the fourth side wall 4316 extending upward from the bottom wall 4311, but not extending to the top wall 4313, and being provided to extend only a distance, so that a space for accommodating solids may be formed by the fourth side wall 4316, the second side wall 4314, the third side wall 4315 and the bottom wall 4311, and also the garbage may be conveniently cleaned through the opening part. The end surfaces of the fourth side wall 4316, the second side wall 4314, the third side wall 4315, and the top wall 4313 may be provided to fit the inner wall of the recovery storage section 400.

A space is opened on the top wall 4313 and a filter screen (not shown) is detachably installed to constitute the filter portion 433, wherein the space may be shaped like an L and opened on the top wall 4313 adjacent to the first side wall 4312. Further, a duct support part 436 may be provided on the top wall 4313, and the duct support part 436 extends toward the inside of the solid storage part 431 by a predetermined length so as to support an end (an open end) of the recovery duct. Further, after supporting the end of the recovery conduit, the open end of the recovery conduit may face the top wall 4313 and be spaced a distance from the top wall 4313. As shown in fig. 20, since the top wall 4313 is provided between and separates the open end of the recovery conduit and the gas-liquid separator 422, the recovered liquid from the open end of the recovery conduit can be prevented from reaching the gas-liquid separator 422 by the blocking action of the top wall 4313. After the recovered liquid with the entrained solids enters the space formed by the solids storage portion 431 through the recovery conduit, the solids are retained in the space of the solids storage portion 431 by the filter portion 433 in the form of a filter net or the like, and only the liquid is allowed to enter the space where the gas-liquid separator 422 is located through the filter portion 433, so that the solids remain in the solids storage portion 431.

The second anti-surge portion 434 is provided in the form of a partition plate, and one or more liquid through holes are opened in the partition plate so as to allow the passage of the recovered liquid, and when the recovered liquid passes through, the rapidly varying liquid is prevented from forming waves in the recovered storage portion 400 by the blocking effect of the partition plate, and the liquid in the spaces on both sides of the second anti-surge portion 434 is allowed to communicate through the liquid through holes.

For example, when the surface cleaning apparatus is changed from the upright posture to the inclined use posture, or the parallel posture (lying posture), or from the inclined use posture to the parallel posture, the reclaimed liquid stored in the reclaimed storage section 400 may generate waves due to the change in the angle of the surface cleaning apparatus, and the liquid may enter the gas-liquid separator 422 without being suppressed. The waves can be blocked by the partition of the second anti-surge portion 434, and the liquid can also be made to flow through the liquid through-holes provided in the partition. At least one (e.g., three) end surfaces of the second anti-surge portion 434 may be bonded to the inside of the recovery storage portion 400.

Further, the open area occupied by the filter portion 433 may be set to be greater than or equal to the open area occupied by the one or more liquid through holes provided by the second anti-surge portion 434 (e.g., the total open area occupied by the two filter portions 433 may be set to be greater than or equal to the total open area occupied by the liquid through holes), so that air is mainly taken into the gas-liquid separator 422 from the position of the filter portion 434 at least when the surface cleaning apparatus is in the parallel posture. Thus, when viewed in the parallel posture, the liquid is prevented from reaching the gas-liquid separator 422 from the lower portion of the first antisurge portion 435 through the first antisurge portion 435, and the gas-liquid separation effect of the gas-liquid separator 422 is affected.

The first anti-surge portion 435 is disposed opposite the gas-liquid separator 422, and optionally, the central axis of the first anti-surge portion 435 and the central axis of the gas-liquid separator 422 are parallel to or coincide with each other, and in the present disclosure, preferably, the two central axes coincide with each other (as shown in fig. 20). Wherein the central axis of the gas-liquid separator 422 may be an axis where the center of the driving shaft thereof is located, and the central axis of the first anti-surging portion 435 may be a central axis of a hollow portion of the first anti-surging portion 435 mentioned below.

As shown, the first anti-surge 435 may include an edge portion 4351, a transition portion 4352, and a hollow portion 4353. The transition portion 4352 is located between the edge portion 4351 and the hollow portion 4353. From the plane in which the edge portion 4351 lies, the transition portion 4352 extends obliquely to the hollow portion 4353, such that the transition portion forms a bevel between the edge portion 4351 and the hollow portion 4353. When the surface cleaning apparatus mounted with the recovery storage 400 is in the parallel posture, the inclination direction of the transition portion 4352 is the downward direction, and the inclination direction of the transition portion 4352 is the direction away from the gas-liquid separator 422.

So that the liquid in the space where the gas-liquid separator 422 is located can enter the first anti-surge portion 435 and slide down along the transition portion 4352. Further, due to the shape setting of the first anti-surge portion 435, when the surface cleaning apparatus is changed from the upright posture to the inclined use posture, or the parallel posture (lying posture), or from the inclined use posture to the parallel posture, the waves generated by the angle change can be offset by the first anti-surge portion 435 due to the angle change of the surface cleaning apparatus, thereby preventing the liquid from entering the gas-liquid separator 422 due to the waves.

Furthermore, when the surface cleaning apparatus (correspondingly the recovery storage 400) is changed in posture between the inclined use posture and the parallel posture, waves may also form between the first and fourth chambers, which waves may affect the open end of the recovery conduit 440 and may even affect the gas-liquid separator 422. To avoid these effects, the bottom wall 4311 may act as a third anti-surge, wherein waves may be counteracted by avoidance of the bottom wall 4311 when the waves contact the bottom wall 4311, and fluid communication between the first and fourth chambers is achieved through the liquid guiding holes of the bottom wall 4311. In addition, in an alternative embodiment, the first side wall 4312 may also be used as a third anti-surge portion, and the principle of the implementation is the same as that of the bottom wall 4311, which is not described herein.

Thus, according to the above-described manner of the present disclosure, a three-stage anti-surge function can be achieved, thereby preventing a large amount of liquid from entering the gas-liquid separator 422.

As described above, when the user needs to clean up the trash in the filter 430, it can be taken out of the recovery storage section 400, so that the first anti-surge section 435 can serve as a hand-held section for the user to extract the filter 430. When the first storage part 406 and the second storage part 407 are separated, a user may access the filter 430 accommodated therein through the opening of the second storage part 407 and then take out the filter 430 by holding the first anti-surge part 435. In an alternative embodiment, when the filter 430 is installed into the second storage portion 407, the first anti-surge portion 435 protrudes outward relative to the second storage portion 407 for the user to hold; the second storage portion 407 is formed by a plurality of wall portions and has an opening.

In the present disclosure, the filter 430 may be integrally formed or fixedly provided, and as shown in fig. 20, the extension axes of the top wall 4313 and the second anti-surge portion 434 coincide, or may be one plate-shaped portion, and the solid storage portion 431 is located at one side of the plate-shaped portion, and the first anti-surge portion 435 is located at the other side of the plate-shaped portion. The first anti-surge portion 435 may be fixed to the top wall 4313 or integrally formed with the top wall 4313 or the like, and with respect to a central axis of the solid storage portion 431 (a central axis extending in a height direction of the recovery storage portion 400 in the upright posture), an extending direction of the first anti-surge portion 435 is deviated from the central axis so as to lift the filter 430, and a larger installation space is provided to the filter portion 433.

The inner cavity of the recovery storage portion 400 may be divided into a first cavity, a second cavity, and a third cavity according to a space formed by the filter 430 and the housing of the recovery storage portion 400. Wherein the first cavity is a space formed by the second anti-surge portion 434 and the first sidewall 4312; the second cavity is a space formed by the first anti-surge part 435 and the second anti-surge part 434; the third cavity is a space formed by the first anti-surge part 435 and the top wall 4313, that is, a space where the gas-liquid separator 422 is located; the fourth cavity is a space where the solid storage portion 431 is located.

The formation of waves in the second chamber is prevented by the second anti-surge portion 434 when liquid flows from the first chamber to the second chamber and the formation of waves in the third chamber is prevented by the first anti-surge portion 435 when liquid flows from the second chamber to the third chamber.

On the other hand, fig. 65 to 68 show schematic structural views of a filter according to another embodiment of the present disclosure. As shown in fig. 65 to 68, the present disclosure also provides a filter 430 of another structure, and for convenience of description, the same structure as the filter 430 described above will not be described in detail.

When the surface cleaning apparatus is in a working state, the recovery storage portion is at least divided into a first chamber and a second chamber, wherein the first chamber may be a chamber for storing recovered solids, or a chamber corresponding to the solid storage portion of the filter 430, and the second chamber may be a chamber for storing recovered liquid; in another structure of the filter 430, it includes a connection pipe 437, the connection pipe 437 for connecting the first chamber and the second chamber.

The recovery storage part 400 includes a partition part, and the recovery storage part 400 is partitioned into a first chamber and a second chamber which are isolated from each other by the partition part of the recovery storage part 400; for example, when the recovery storage section 400 includes a first storage section 406 and a second storage section 407, the second storage section 407 has an opening, and the second storage section 407 includes a partition section 4071, and the second storage section 407 is partitioned into a first chamber and a second chamber isolated from each other by the partition section 4071.

Alternatively, the filter 430 includes a partition portion, and when the filter 430 is mounted to the recovery storage portion 400, the partition portion of the filter 430 partitions the recovery storage portion 400 into a first chamber and a second chamber that are isolated from each other; the sidewall of the solid storage 431 of the filter 430 may be formed as a partition of the filter 430, for example, the first sidewall 4312 of the filter may be formed as a partition of the filter 430. In this implementation, the first chamber may be similar to the fourth chamber described above, the second chamber may be similar to the first chamber described above, and of course, the first chamber and the fourth chamber may be different, and the second chamber and the first chamber may also be different.

Of course, the second storage portion 407 may also be divided into the first chamber and the second chamber by the filter 430, for example, by cooperation of the filter 430 with a wall surface of the second storage portion 407, so that the second storage portion 407 is separated by the filter 430 into the first chamber and the second chamber that are isolated from each other.

In the present disclosure, the first, second and

third side walls

4312, 4314, 4315 of the solid storage part 431 form side walls of the solid storage part 431, and the top wall 4313 of the solid storage part 431 is provided corresponding to the first chamber, and the first chamber is formed as a sealed chamber, that is, the top wall 4313 is not formed with the filter part 433, but is formed as a plate-shaped member.

In the present disclosure, the bottom wall 4311, the side walls, and the top wall 4313 collectively form a chamber storing the recovered solids, i.e., the recovered solids are stored in the chamber storing the recovered solids when the filter 430 is detached from the inside of the recovery storage portion 400, and only the recovered liquid remains in the recovery storage portion.

At least part of the periphery of the second anti-surge portion 434 of the filter 430 and at least part of the periphery of the top wall 4313 of the solid storage portion 431 are disposed in contact with the wall surface forming the recovery storage portion 400; for example, the second anti-surge portion 434 is provided corresponding to the second chamber and is formed as a top of the second chamber.

Preferably, one end of the connection tube 437 is near the bottom of the first chamber, and the other end of the connection tube 437 is near the top of the second chamber; the other end of the connection pipe 437 is close to the second anti-surge portion 434, and the opening of the other end of the connection pipe 437 is directed to the second anti-surge portion 434 and is located above the second anti-surge portion 434; at least part of the connection tube 437 is located in the first chamber. More preferably, the side wall of the solid storage part is formed as a part of the pipe body of the connection pipe 437.

Also, at least part of the bottom wall 4311, the side walls, and the top wall 4313 is formed in a porous structure, for example, the first side wall 4312, the second side wall 4314, and the third side wall 4315 of the side walls may all be formed in a porous structure, in which case the holes formed by the first side wall 4312 do not communicate with the connection pipe 437; of course, the first sidewall 4312 may not be formed in a porous structure, but only one of the second sidewall 4314 and the third sidewall 4315 may be formed in a porous structure.

At least part of the first anti-surge portion of the filter 430 is located in the recovery storage portion 400 (when the recovery storage portion 400 is of an integral structure), or in a storage space formed by at least part of the first storage portion 406 and at least part of the second storage portion 407 (when the recovery storage portion 400 includes the first storage portion 406 and the second storage portion 407), wherein the first storage portion may also be formed on the main body portion 200.

In the present disclosure, the structure of the hollow portion 4353 is slightly different from that of the aforementioned filter 430, in particular, the hollow portion 4353 forms the edge portion 4351 and the transition portion 4352 into an opening shape so that the recovered liquid discharged from the connection tube 437 directly passes through the hollow portion 4353 without contacting the transition portion 4352; of course, it is also possible to employ a hollow portion 4353 which is similar to a circular shape.

Fig. 22 shows an oblique cross-sectional view of the recovery storage section 400. Fig. 23 shows a partial cross-sectional view of the recovery storage section 400.

Fig. 22 and 23 show schematic views of the recovery storage section 400 in a parallel posture. It should be noted that, although the description is given taking the parallel posture as an example, the principle is the same in the case of the inclined use posture and the upright posture, and will not be described again.

In the present disclosure, a suction source 460 (shown in fig. 3) may be provided in the recovery flow path to suction the recovered liquid, gas, and/or solids, wherein the suction source may be provided at a location downstream of the gas-liquid separator 422. Wherein the suction source may be provided in one housing, and the housing may include a suction motor housing, which may house the suction motor, and a fan housing, which may house the fan. The other two may also be provided in one housing. The fan housing may include a gas inlet for drawing gas into the fan housing, and the gas inlet may be generally aligned with a central region of the fan, which may be the central axis of the motor, for example. The fan housing may also include a gas outlet through which the gas is exhausted. The suction motor may be a brushless dc motor, which may be powered directly by a rechargeable battery. In the case of supplying power by a wired manner, an ac/dc conversion means may be provided in the control circuit portion so as to convert ac power into dc power to be supplied to the motor, thereby realizing long-duration cleaning.

The suction source 460 is provided at a position independent from the recovery storage section 400, and may be provided in the upper case 210 of the main body section 200, for example. Wherein the upper housing 210 and the frame 220 may be detachably installed or integrally formed. A power supply portion 800 such as a rechargeable battery and a control circuit portion 700 may also be accommodated in the upper case. In addition, a sound device 900 is provided at a side of the upper case 210, and the sound device 900 may be connected to the control circuit part 700 so as to emit sound through the sound device 900 to prompt a user or the like.

The recovered liquid, gas and/or solids are drawn in through the recovery conduit 440 and into the fourth chamber where the solids (e.g., solid waste other than debris) will remain in the solids storage 431. Some or all of the liquid can flow into the first chamber through the liquid-guiding apertures in the bottom wall 4311 and/or the first side wall 4312, and gas, liquid and/or water vapor (which may also be present as different debris filtered by the filter) will pass through the filter 433 into the third chamber, where the filter 433 acts as a barrier to solids and allows liquid and gas (which may be entrained with some debris) to pass. In the third chamber, the gas and liquid are separated by the gas-liquid separator 422 so that the gas passes and exits along the channel, leaving the liquid (possibly with debris) in the third chamber (the liquid and/or small particle waste is thrown out in the third chamber by rotation of the gas-liquid separator 422). In the parallel posture or the inclined use posture of the recovery storage section 400, the liquid of the third chamber may enter the second chamber through the hollow portion of the first anti-surge section 435. And the first and second chambers may be in fluid communication through the liquid through-hole of the second anti-surge portion 434, wherein in the upright posture or the inclined use posture of the recovery storage portion 400, the liquid of the third chamber may flow into the fourth chamber through the filtering portion 433 and then flow into the first chamber from the fourth chamber.

The flow path of the gas is shown by arrows in fig. 22, wherein the gas enters the recovery conduit 440 from the inlet port 404, merges into the first chamber along the recovery conduit 440, then flows into the second chamber via the filter 433, is separated by the gas-liquid separator 422, and is then discharged from the exhaust port 408 through the gas channel.

The recovery conduit 440 (or its central axis) is disposed offset from and may be parallel to the longitudinal central axis of the recovery storage 400. Which is disposed so that the recovery conduit 440 is closer to the main body portion or to the cleaning liquid storage portion 300 than the longitudinal central axis in a posture of being mounted to the recovery storage portion 400. In the present disclosure, when the recovery storage 400 is in the parallel posture, the position of the recovery duct 440 may be disposed near the upper side of the recovery storage 400, and in the case where the recovery storage 400 is in the upright posture or the inclined use posture, the position of the recovery duct 440 may be disposed near the front side of the recovery storage 400. Further, in alternative embodiments of the present disclosure, the recovery conduit 440 may be fixed to or integrally formed with the wall of the recovery storage 400. This prevents liquid from the recovery tank 400 from entering the recovery conduit 440 when the surface cleaning apparatus is in a parallel position (lying flat). The liquid level of the recovery storage 400 may also be made lower than the open end of the recovery conduit 440 to prevent recovery liquid from entering the recovery conduit 440 when the surface cleaning apparatus is in an upright position or an inclined use position.

As shown in an enlarged portion of a portion of fig. 23, in order to prevent leakage of liquid or moisture or the like from the third chamber into the gas passage so that the gas-liquid separation effect is deteriorated, a labyrinth seal structure may be provided at a connection portion of the third chamber and the gas passage, wherein the labyrinth seal structure may include a first barrier 451, a second barrier 452, and a third barrier 453, wherein the first barrier 451 may be disposed at an upstream position, the second barrier 452 may be disposed at a midstream position, and the third barrier 453 may be disposed at a downstream position in a direction from the third chamber to the gas passage. The first baffle 451 and the third baffle 453 may be provided on the bracket (or the wall body thereof) of the recovery storage section 400, and the second baffle 452 may be provided on the gas-liquid separator 422 (e.g., the housing of the gas-liquid separator 422). When the recovery storage 400 is in the parallel posture, the extending directions of the first barrier 451 and the third barrier 453 are downward, and the extending direction of the second barrier 452 is upward. Thus, the first barrier 451, the second barrier 452, the third barrier 453, the support (or the wall) of the recovery storage section 400, and the housing of the gas-liquid separator 422 can form a three-stage labyrinth structure, so that liquid or moisture, etc. can be prevented from entering the gas passage. In one embodiment of the present disclosure, the liquid level detection portion 405 may be used to detect the liquid level of the liquid in one or more postures in the recovery storage portion 400, for example, may detect a parallel posture, a self-supporting state, and a liquid of the recovered liquid in at least one of the parallel posture and the self-supporting state.

The first limit liquid level threshold of the liquid level detection device is set as follows: when the recovery storage part is in a parallel posture, the liquid level is a first preset distance from the gas-liquid separator so as to prevent the recovery storage part from exceeding a first limit liquid level threshold. Preferably, the height at or below which the first anti-surge portion is located is set as the first limit liquid level threshold. Preferably, a height at or below which the lowest point of the first anti-surge portion is located is set as the first limit liquid level threshold. The second extreme liquid level threshold of the liquid level detection device is set as: when the recovery storage part is in a vertical posture parallel to the horizontal posture, the liquid level is a second preset distance from the gas-liquid separator, so that the recovery storage part is prevented from exceeding a second limit liquid level threshold. Preferably, the height at or below which the second anti-surge portion is located is the second limit liquid level threshold. The liquid level detection device comprises more than two liquid level detection parts, and at least two liquid level detection parts are arranged on the liquid level height of the first limit liquid level threshold; more preferably, the liquid level detection portion is provided below the liquid level height of the first limit liquid level threshold. Optionally, the liquid level detection device comprises more than two liquid level detection parts, and at least two liquid level detection parts are arranged on the liquid level height of the second limit liquid level threshold. Optionally, the liquid level detection device comprises more than two second liquid level detection parts, and one or more than two liquid level detection parts are arranged on the liquid level height of the second limit liquid level threshold; more preferably, one or more second liquid level detecting portions are provided below the liquid level height of the second limit liquid level threshold. Further, it should be noted that the first liquid level detection portion may be reusable with the second liquid level detection portion. Through the arrangement of the first liquid level detection part and the second liquid level detection part, accurate detection can be respectively carried out at corresponding postures, so that detection interference caused by liquid shaking is avoided.

Further, in the case of obtaining the liquid level in the recovery storage section 400, whether to interrupt the recovery system may also be controlled according to the detected liquid level, thereby turning off the surface cleaning apparatus or the like. The liquid detection portion 405 may be any suitable detection device or element, etc. In the present disclosure, the liquid level detection portion may be in the form of a sensor, for example, may be in the form of a metal probe. The following description will be given by taking a metal probe sheet as an example, but it should be understood by those skilled in the art that other detecting means may be used.

The metal probe may be provided at an inner side or an outer side of the recovery storage part 400, and preferably may be provided at an outer side of the recovery storage part 400. And it is more preferable in the present disclosure that the metal probe sheet is provided on a side of the recovery storage section 400 facing the frame body. The number of metal probe pieces may be set to two or other numbers, the number of metal probe pieces being selected so that at least the level of the recovered liquid can be detected in the upright posture and the parallel posture, and more preferably also in the inclined use posture.

According to one embodiment, as shown in fig. 24 and 25 (fig. 24 shows a schematic view of the recovery storage 400 in an upright posture, fig. 25 shows a schematic view of the recovery storage 400 in a parallel posture), four or more liquid level detecting portions (metal probe pieces) may be provided, and the four or more liquid level detecting portions may be provided in a row-column manner, for example, in the case of four shown in the drawings, the four liquid level detecting portions may be provided in a two-row two-column manner. Although an arrangement is illustrated here, an irregularly shaped arrangement is also possible.

For example, when the level of the recovered liquid is detected in the upright posture, the height of the liquid level can be obtained by the two rows of liquid level detecting portions. Of course, those skilled in the art will appreciate that more level detecting portions may be provided for higher accuracy. For example, when measuring the liquid level of the recovery storage 400 in the upright posture, the liquid level measurement may be performed by a set of liquid level detection sections arranged along the height direction of the recovery storage 400. Further, the uppermost liquid level detection means may be provided at a capacity threshold position of the recovery storage 400 to prevent the liquid from exceeding the threshold height, and when the threshold height is reached, the surface cleaning apparatus may alarm to remind the user to perform a treatment.

When the liquid level of the recovered liquid is detected in the parallel posture, the height of the liquid level can also be obtained by the two rows of liquid level detection portions. For example, when measuring the liquid level of the recovery storage 400 in the upright position, the liquid level measurement may be performed by a set of liquid level detection units arranged in the thickness direction of the recovery storage 400. Alternatively, the uppermost liquid level detection device may be provided at a capacity threshold position of the recovery storage 400 to prevent liquid from exceeding the threshold height, upon reaching which the surface cleaning apparatus may alarm to alert the user to the process. For example, the threshold height may be a height below the open end of the recovery conduit (whether in an upright position, an inclined use position, or a parallel position).

In addition, when the liquid level of the recovered liquid is detected in the inclined use posture, the liquid level may be detected by a liquid level detecting device provided in a row.

Furthermore, the liquid level detection means may also be used to detect whether the recovery storage 400 is present on the surface cleaning apparatus. For example, the fluid level detection means may cooperate with sensing means provided on the frame body of the main body 200, for example in the case of mutual sensing signals, the recovery storage section 400 is considered to be present on the surface cleaning apparatus.

Continuing with the description of the metal probe, the metal probe is disposed on a side of the recovery storage part 400 facing the frame body, and a conductive sheet may be disposed on the frame body, and when the recovery storage part 400 is installed, the conductive sheet may supply power to the metal probe, thereby enabling the metal probe to detect a liquid level and/or the existence of the recovery storage part 400. Although metal probe and conductive sheets are described herein as examples, it should be understood that the two may take any other suitable form.

In addition, the liquid level detecting portion and the detecting portion that detects the presence or absence of the recovery storing portion 400 may be provided separately, that is, in an independent detecting manner for the two functions, respectively. In addition, two or more sets of detection units may be provided to perform two or more detection functions, respectively.

Further, as shown in fig. 26, an electric line accommodating portion 230 may be further provided in the space between the cleaning liquid storage portion 300 and the recovery storage portion 400. The electric wire receiving part 230 may be provided in the frame body 220, and may be fixed to the frame body 220, for example. The electric wire receiving part 230 may extend from the entire height of the cleaning liquid storage part 300 and the recovery storage part 400 or from the lower ends of the cleaning liquid storage part 300 and the recovery storage part 400 to the vicinity of the control circuit part 700 and/or the power supply part 800.

The electric wire receiving part 230 may have a long bar shape having a groove, and a power supply wire, a control wire, etc. may be received in the electric wire receiving part 230 so as to be in electrical communication with the cleaning base part 600.

In addition, as an alternative embodiment, a receiving portion in the form of a groove or the like may be provided on the frame body 220 as the above-described electric wiring receiving portion 230. The conductive sheet may be provided on the electric wire storage part 230.

In the present disclosure, the detection portion of the liquid level detection device is located close to the rear of the surface cleaning apparatus with respect to the recovery conduit. The detection portion of the liquid level detection device is one or more detection portions arranged from the outlet of the recovery conduit to the rear of the surface cleaning apparatus so that the liquid level of the recovery liquid of the recovery storage portion in at least one of the intermediate posture of the parallel posture and the self-supporting posture can be detected. The detection unit communicates between the inside and the outside of the recovery box, and may penetrate through a wall of the recovery storage unit, for example. As shown, the detection portion may include a first arrangement and a second arrangement, the first arrangement and the second arrangement being arranged along a longitudinal direction of the surface cleaning apparatus. Preferably, the first arrangement comprises at least a first probe point and a second probe point, the second arrangement comprises at least a third probe point and a fourth probe point, and electrical communication can be realized between every two of the first probe points and the fourth probe points. When the first probe point and the third probe point or the second probe point and the fourth probe point are in a parallel posture, the first probe point and the third probe point or the second probe point and the fourth probe point are communicated; when in the vertical posture and/or the self-supporting posture, the first detection point is communicated with the second detection point or the third detection point is communicated with the fourth detection point.

When the surface cleaning apparatus performs a suction operation, a suction source 460 located downstream performs a suction operation, drawing gas from the exhaust port 408 and then discharging the gas out of the surface cleaning apparatus. Upstream of the suction source 460 is the recovery storage 400, and the recovery conduit 440 in the recovery storage 400 receives the recovery liquid, gas, solid, and the like from the suction of the cleaning base 600 from the outlet 506, and the recovery conduit 440 introduces the recovery substance into the recovery storage 400, the liquid and solid remain in the recovery storage 400, and the gas is discharged from the gas outlet 408 through the gas passage by the gas-liquid separator 422. Furthermore, one or more additional filters may be provided in the gas channel. For example, an additional filter may be provided downstream of the suction source 460 and/or between the upstream thereof and the recovery storage 400.

Specifically, the cradle portion includes a mechanical connector corresponding to the housing module that is simultaneously aligned with a mating connector of the housing module when the cradle portion is accessed into the housing module mated therewith. And the bracket portion 618 is connected to at least the first rotating portion into which at least a portion of the cleaning drive device slides when the bracket portion is mounted to the housing module; more specifically, when the bracket portion is mounted to the housing module, the transmission slides into the first rotating portion inner cavity and a mechanical connection of the transmission and the first rotating portion is achieved.

As shown in fig. 30 and 31, when the cleaning module 610 includes only the first rotating portion 6111 and the ring 6112 provided outside the first rotating portion 6111, the cleaning module 610 is formed in the form of a roll brush. As shown in fig. 32 and 33, the cleaning module 610 may also be formed as an endless belt type cleaning device, in which case the cleaning module 610 further includes a second rotating portion 6113, the second rotating portion 6113 is disposed parallel to the first rotating portion 6111, and one end of the second rotating portion 6113 is rotatably disposed to the housing module 650.

The ring 6112 is disposed around the first rotating portion 6111 and the second rotating portion 6113, and the ring 6112 positioned below the first rotating portion 6111 and the second rotating portion 6113 is brought into contact with the surface to be cleaned.

The outer diameters of the first rotating portion 6111 and the second rotating portion 6113 may be the same or different. When the outer diameters of the first rotating portion 6111 and the second rotating portion 6113 are different, it is preferable that the diameter of the first rotating portion 6111 be larger than the diameter of the second rotating portion 6113.

The cleaning surface is located on the ring 6112 and the ring is time for power transfer between the first rotating portion 6111 and the second rotating portion 6113.

The second rotating part 6113 is arranged in front of the first rotating part 6111, namely, the first rotating part 6111 is close to the rear side of the cleaning module, and the second rotating part 6113 is close to the front side of the cleaning module, with the moving direction of the surface cleaning device for cleaning the surface to be cleaned as the forward direction; of course, the second rotating portion 6113 may also be disposed behind the first rotating portion 6111, and a person skilled in the art may realize the position adjustment of the second rotating portion 6113 according to the technical knowledge.

Fig. 38 shows a schematic structural view of a ring 6112 according to another embodiment of the present disclosure. In the present disclosure, in another case, a soft adhesive layer 6111E is provided in a region between the two annular grooves 6111C and/or between the annular groove 6111C and the outer flange portion 6111A, so as to increase friction between the first rotating portion 6111 and the annular member 6112 through the soft adhesive layer 6111E, and prevent relative sliding between the annular member 6112 and the first rotating portion 6111. More preferably, the soft gel layer 6111E may be made of natural or synthetic rubber, such as Ethylene Propylene Diene Monomer (EPDM) or nitrile rubber, or a soft material such as silica gel. On the other hand, the soft adhesive layer 6111E may also be provided with an external tooth portion 6111B, so as to further prevent the relative sliding between the first rotating portion 6111 and the annular member 6112 by using the soft adhesive layer 6111E with the external tooth portion 6111B.

Fig. 39 shows a schematic cross-sectional view of fig. 37. Fig. 40 shows a schematic cross-sectional view of fig. 38. As shown in fig. 39 and 40, the radial dimension of the outer flange portions 6111A at both ends of the first rotating portion 6111 and/or the second rotating portion 6113 of the present disclosure is smaller than the thickness of the annular member 6112, so that the outer flange portions 6111A of the first rotating portion 6111 and/or the second rotating portion 6113 do not contact the surface to be cleaned when the cleaning module 610 performs a cleaning operation, damage to the surface to be cleaned by the first rotating portion 6111 and/or the second rotating portion 6113 is effectively prevented, and the cleaning effect is also improved.

Considering that the second rotating portion 6113 of the present disclosure is similar to the structure of the first rotating portion 6111, a person skilled in the art can know the structure of the second rotating portion 6113 according to the structure of the first rotating portion 6111, and a legend of the second rotating portion 6113 is not provided based on this disclosure.

Fig. 41 shows a schematic view of a process of manufacturing a ring according to one embodiment of the present disclosure. In the present disclosure, the endless member 6112 is an important part of the cleaning work, and the flexible endless belt portion is in direct contact with the surface to be cleaned when the cleaning work is performed using the surface cleaning apparatus. Preferably, the ring member 6112 includes a cleaning body 6112A and a base material 6112B, and the cleaning body 6112A is similar to the cleaning body 6112A of a general floor brush, and a nap material of a wiping cloth type can be selected. The base material 6112B is generally a flexible soft material, and the cleaning body 6112A may be fixed to the base material 6112B by means of gluing, sewing, or the like, so that the entire ring-shaped member 6112 is wound around the first rotating portion 6111 or around the first rotating portion 6111 and the second rotating portion 6113 which are parallel to each other.

In view of the particularity of the ring 6112 of the present disclosure, the present disclosure provides a method of preparing the ring 6112, comprising: s601, preparing a base material 6112B using a flexible material, wherein a cross section of the base material 6112B is annular. The flexible material of the base material 6112B may be rubber, fiber cloth, or the like, so that the endless member 6112 can function like a conveyor belt. S602, tensioning the base material 6112B by using at least two tensioning rollers, and applying an adhesive to the outer peripheral surface of the base material 6112B. In the present disclosure, at least one of the tension rollers may be driven to be rotatable so that the base material 6112B moves on the tension roller, thereby enabling the adhesive to be conveniently applied on the outer surface of the base material 6112B. S603, applying an adhesive on one surface of the cleaning body 6112A, and placing the cleaning body 6112A on the base material 6112B, and after the adhesive is cured, removing the base material 6112B from the tension roller, thereby obtaining the endless member 6112.

Those skilled in the art will appreciate that after the adhesive is applied to the outer surface of the tensioning roller, no adhesive may be applied to the surface of the cleaning body 6112A. Alternatively, the adhesive may be applied only to the outer peripheral surface of the tension roller and one surface of the cleaning body 6112A. However, in order to provide the ring 6112 with a better cleaning effect, the ring 6112 of the present disclosure has an adhesive applied to both the outer circumferential surface of the tension roller and the surface of the ring 6112 during the manufacturing process.

More preferably, in order to improve the service life of the ring 6112 and prevent separation between the base material 6112B of the ring 6112 and the ring 6112, the circumferential direction of at least one end of the ring 6112 in the present disclosure is stitched by the stitching line 6112C, that is, at least one end of the cleaning body is refastened with at least one open end of the base material, whereby, in use, the ring 6112 of the present disclosure can avoid the use of the manner of pressing the end cap that is conventional at present, thereby reducing the cleaning-to-edge distance of the cleaning body 6112A. More preferably, both ends of the cleaning body 6112A are sewn by a suture 6112C.

FIG. 42 shows a schematic view of a ring made in accordance with one embodiment of the present disclosure. FIG. 43 shows a schematic cross-sectional view of a ring according to one embodiment of the present disclosure.

Fig. 49 shows a schematic view in which the first and second rotating parts are installed according to one embodiment of the present disclosure. As shown in fig. 49, when the detachable endless belt cleaning assembly is mounted to the housing module 650, considering that the flexible endless belt portion is in a tensioned state, the first rotating portion 6111 and the second rotating portion 6113 may approach each other under the force applied by the flexible endless belt portion, resulting in that the first rotating portion 6111 and the second rotating portion 6113 cannot be aligned exactly with the first support bearing and the second support bearing, and the first rotating portion 6111 and the second rotating portion 6113 need to maintain interference fit with the first support bearing and the second support bearing, respectively, which causes difficulty in mounting, and the user experience is poor when cleaning the replacement scenario endless belt and when mounting and dismounting the entire cleaning endless belt assembly.

Fig. 50 illustrates a cage mounting position schematic diagram according to one embodiment of the present disclosure. Fig. 51 shows a schematic view of a cage according to one embodiment of the present disclosure in a separated state. At this time, as shown in fig. 50 and 51, the detachable endless belt cleaning assembly further includes a holder 6114, the holder 6114 being provided to the first rotating portion 6111 and the second rotating portion 6113 for defining positions of the first rotating portion 6111 and the second rotating portion 6113 so as to prevent the first rotating portion 6111 and the second rotating portion 6113 from approaching to each other.

Preferably, the holder 6114 is provided in at least one, and when the holder 6114 is provided in one, the holder 6114 is provided at one end of the first rotating portion 6111 and the second rotating portion 6113 away from the bracket portion 618; when the number of the holders 6114 is set to two, the holders 6114 may be provided at both ends of the first rotating portion 6111 and the second rotating portion 6113. That is, in the present disclosure, the flexible endless belt portion may be made into a consumable material, and the holder 6114 may be installed at the other side of the bracket portion 618, so that the first rotating portion 6111 and the second rotating portion 6113 are prevented from being close to each other due to the tensioning action of the flexible endless belt portion, so that the entire detachable endless belt cleaning assembly can be easily attached to the surface cleaning apparatus.

The cost of manufacturing the whole detachable annular belt cleaning assembly into consumable materials is too high, so that the flexible annular belt part and the retainer 6114 can be considered to be used as consumable materials together, and the retainer 6114 is arranged on two sides of the cleaning annular belt, so that the assembly and replacement of a user are more convenient, and the cost is lower.

Fig. 52 shows a schematic view of a ring 6112 according to one embodiment of the present disclosure. As shown in fig. 52, the circumference of the outer circumferential surface of the ring 6112 of the present disclosure is 20cm or more, so that the problem of hair entanglement in most use environments can be effectively solved. That is, since most of the dropped hairs in the home environment have a length of 20cm or less, when the circumference of the outer circumferential surface of the ring 6112 is set to 20cm or more, the hairs cannot be wound around the ring 6112, so that dirt such as hairs may be scraped off by the scraping plate when the ring 6112 moves, and enter the dirt storage portion via the dirt suction module 630.

Fig. 53 shows a schematic view of a cleaning base 600 in cleaning a surface to be cleaned according to one embodiment of the present disclosure. As shown in fig. 53, when the cleaning base 600 is used to clean a surface to be cleaned, the speed for pushing the surface cleaning apparatus forward on the surface to be cleaned is about 0.5m/s, and if the linear speed of the endless member 6112 is less than 0.5m/s, a certain relative speed may not be formed with the surface to be cleaned, so that the cleaning base 600 cannot be made to clean the same position at least once during pushing and pulling of the surface cleaning apparatus.

However, when the linear velocity of the surface of the flexible endless belt portion in contact with the surface to be cleaned is 0.5m/s or more (the direction of the linear velocity is backward), it is possible to ensure that the surface cleaning apparatus cleans a predetermined area of the surface to be cleaned at least once during use.

The moving wheel module 660 is disposed at the housing module 650 such that the lowest point of the moving wheel module 660 is located below the lowest point of the housing module 650, so that when the surface cleaning apparatus is in operation, the moving wheel module 660 contacts and rolls on the surface to be cleaned to reduce the power required when the surface cleaning apparatus is moved; the moving wheel module 660 is located at the rear side of the housing module 650 to be able to effectively prevent the cleaning base 600 from contaminating the surface that has been cleaned.

In one aspect, as shown in fig. 27 to 29, the moving wheel module 660 is integrally formed with the housing module 650, i.e., the moving wheel module 660 includes: a moving wheel frame 661 and a moving wheel 662; wherein the moving wheel frame 661 is integrally formed with the housing module 650 and is positioned at the rear side of the housing module 650; the moving wheel 662 is rotatably provided to the moving wheel frame 661. In the present disclosure, the moving wheel frame 661 includes two mounting pieces 6611, and the number of moving wheels 662 is two, that is, one moving wheel 662 is mounted on each mounting piece 6611, wherein the two mounting pieces 6611 are located between the two moving wheels 662, or the two moving wheels 662 are located at the outer sides of the two mounting pieces 6611. Of course, those skilled in the art will appreciate that the moving wheel 662 could also be disposed inboard of the mounting 6611.

On the other hand, as shown in fig. 54 to 56, the moving wheel module 660 includes a moving wheel frame 661 and a moving wheel 662. Wherein the moving frame 661 is formed separately from the housing module 650, and the housing module 650 is connected to the moving frame 661 and enables the housing module 650 to move with respect to the moving frame 661. For example, the housing module 650 has at least one rotational degree of freedom with respect to the moving frame 661, and preferably, the housing module 650 has two rotational degrees of freedom with respect to the moving frame 661, i.e., a pitch degree of freedom (Y axis) and a roll degree of freedom (X axis).

The moving wheel frame 661 will be described in detail with reference to the accompanying drawings. As shown in fig. 55, the moving frame 661 includes two mounting pieces 6611 and a connecting portion 6612 connecting the two mounting pieces 6611.

Wherein the number of moving wheels 662 is two, i.e. one moving wheel 662 is mounted on each mounting member 6611, wherein the two mounting members 6611 are located between the two moving wheels 662, or the two moving wheels 662 are located outside the two mounting members 6611. Of course, those skilled in the art will appreciate that the moving wheel 662 could also be disposed inboard of the mounting 6611.

The case module 650 is formed with a connection neck 652, in the present disclosure, an axis of the connection neck 652 is disposed in a front-rear direction, a rotation ring 663 is provided outside the connection neck 652, and the connection neck 652 is allowed to rotate within the rotation ring 663, so that the case module 650 has a tumbling degree of freedom. Also, a rotating ring 663 is rotatably provided to the connection portion 6612, wherein the rotating ring 663 is parallel to the rotating axis of the moving wheel 662 with respect to the rotating axis of the connection portion 6612 and is not on the same straight line, so that the housing module 650 has a pitch degree of freedom.

When the cleaning base 600 is used, since the cleaning area of the flexible endless belt portion is large, if the cleaning area is not flat in the home, one surface is determined by three points, which necessarily results in the moving wheel 662 or the flexible endless belt portion not contacting the ground at the same time, and if only one end of the flexible endless belt portion contacts the ground, the other end of the flexible endless belt portion cannot well contact the ground, which results in an unsatisfactory cleaning effect.

However, the housing module 650 and the moving wheel module 660 of the present disclosure are connected in a hinged manner, so that a relative float is formed between the housing module 650 and the moving wheel module 660, thereby adapting to uneven ground, ensuring effective contact between the flexible endless belt portion and the surface to be cleaned, and ensuring cleaning effect.

As shown in fig. 27 to 29, the cleaning base 600 is mounted to a connection part of the surface cleaning apparatus, for example, detachably mounted to a main body part of the surface cleaning apparatus, by the mounting joint module 640 so that at least part of the cleaning base 600 can be brought into contact with a surface to be cleaned when the surface cleaning apparatus is operated, and cleaning of the surface to be cleaned can be achieved when the cleaning base 600 is moved along a preset path.

The mounting joint module 640 is rotatably provided to the housing module 650 to enable a predetermined angle between the surface cleaning apparatus and the cleaning base 600, for example: when the surface cleaning apparatus is in the inactive state, the surface cleaning apparatus is in the upright state at an angle of about 90 ° to the housing module 650 of the cleaning base 600; when the surface cleaning apparatus is in an operating state, an included angle between the surface cleaning apparatus and the housing module 650 of the cleaning base 600 is 120 ° or more, and even an included angle between the surface cleaning apparatus and the housing module 650 may be 180 °, that is, the surface cleaning apparatus and the housing module 650 are both parallel to the surface to be cleaned, so that the surface cleaning apparatus of the present disclosure can clean the surface to be cleaned under the sofa, the surface to be cleaned under the bed, and the like.

Fig. 57 and 59 illustrate an exploded schematic view of a cleaning base 600 according to one embodiment of the present disclosure. Fig. 58 illustrates a schematic view of another angle of a cleaning base 600 according to one embodiment of the present disclosure. Fig. 60 illustrates a schematic view of another angle of a cleaning base 600 according to one embodiment of the present disclosure. As shown in fig. 57-60, the fluid dispensing module 620 of the cleaning base 600 of the present disclosure is disposed to the housing module 650 for providing cleaning liquid to the cleaning module 610, for example to an endless belt cleaning device, to enable the endless belt cleaning device to wet clean a surface to be cleaned.

The fluid distribution module 620 includes a flow control portion 621 and a fluid distributor 622, wherein the flow control portion 621 is connected to the cleaning liquid storage portion of the surface cleaning apparatus through a first liquid supply line, for supplying the cleaning liquid stored in the cleaning liquid storage portion of the surface cleaning apparatus to the fluid distributor 622 through the flow control portion 621.

The flow control part 621 is connected to the fluid distributor 622 through a second liquid supply line to uniformly supply the cleaning liquid to the surface of the endless belt cleaning device and to maintain the endless belt cleaning device in a wet state to be applied to the surface to be cleaned by the endless belt cleaning device, thereby improving the cleaning quality.

Wherein, when the flow control portion 621 is directly connected to the fluid dispenser 622, the second liquid supply line may not be used; when a heating device is provided between the flow control unit 621 and the fluid dispenser 622, the flow control unit 621 and the fluid dispenser 622 are connected by a second liquid supply line, and in this case, the heating device is provided in the second liquid supply line.

In the present disclosure, the flow control portion 621 may be selected to be a water pump, preferably a peristaltic pump, to better prevent leakage of liquid by the peristaltic pump, and to more precisely control the flow rate provided to the fluid dispenser 622 without the need for a valve such as a check valve.

Wherein the flow control portion 621 is disposed in the housing module 650 and may be located inside the housing module 650, the fluid dispenser 622 is also disposed in the housing module 650 and located on the rear side of the cleaning module 610, such as an endless belt cleaning device.

In the present disclosure, the fluid distributor 622 is a labyrinth fluid distributor 622 such that the cleaning liquid is uniformly distributed on the surface of the endless belt cleaning device. The cleaning base 600 further includes an upper case 670, the upper case 670 being provided to the case module 650, and forming a portion of an outer surface of the cleaning base 600, and at least partially covering the cleaning assembly; for example, the upper case 670 is detachably provided to the case module 650, and preferably, the rear portion of the upper case 670 is detachably provided to the case module 650, and the front portion of the upper case 670 is positioned above the ring 6112 and at least partially covers the ring 6112.

As shown in fig. 64, the fluid dispenser 622 may include one or more water outlets, which may be formed in the housing module 650 or in the upper housing 670. In one implementation, the plurality of water outlets form a column configuration.

The cleaning liquid flowing out to the surface of the annular member 6112 through the water outlet passes through the brush plate portion 671, and is uniformly distributed on the surface of the annular member 6112.

Wherein the brush plate portion 671 is provided to the upper case 670 or integrally formed with the upper case 670, in one implementation form, the brush plate portion 671 extends in a length direction of the cleaning module, and both ends of the brush plate portion 671 are not shorter than both ends of the ring.

More preferably, the brush plate portion 671 is located at the downstream side of the fluid distributor 622 in the moving direction of the endless member of the cleaning module, so that when the fluid distributor 622 supplies the cleaning liquid to the endless member of the cleaning module, the cleaning liquid is more uniformly distributed on the surface of the endless member 6112 by the brush plate portion 671, and at this time, the brush plate portion 671 is in contact with the surface of the endless member.

The fluid dispenser 622 may be mounted to the upper case 670, or the fluid dispenser 622 may be integrally formed with the upper case 670, thereby supplying the cleaning liquid to the outer surface of the rear portion of the ring 6112 and applying the cleaning liquid to the surface to be cleaned as the ring 6112 moves.

The fluid dispenser 622 and the surface of the endless belt cleaning device have a preset interval therebetween, wherein the magnitude of the preset interval may be different according to the pressure of the cleaning liquid outputted from the flow control portion 621, for example, when the pressure of the cleaning liquid outputted from the flow control portion 621 is large, the preset interval is also large, and correspondingly, when the pressure of the cleaning liquid outputted from the flow control portion 621 is small, the preset interval is also small. When the cleaning module 610 is an endless belt type cleaning device, if the inner surface of the flexible endless belt portion enters foreign matter, the foreign matter may enter between the flexible endless belt portion and the first rotating portion 6111 or into an area between the flexible endless belt portion and the second rotating portion 6113, possibly causing damage to the endless belt.

For this reason, as shown in fig. 57 and 58, when the flexible endless belt portion is wound around the first rotating portion 6111 and the second rotating portion 6113, the upper edge of the mounting portion 651 is formed not lower than the lower surface of the upper portion of one end of the flexible endless belt portion, and the lower edge of the mounting portion 651 is formed not higher than the upper surface of the lower portion of one end of the flexible endless belt portion, so that the mounting portion 651 can close one end of the flexible endless belt portion.

Accordingly, the upper edge of the holder portion 618 is formed not lower than the lower surface of the upper portion of the other end of the flexible endless belt portion, and the lower edge of the holder portion 618 is formed not higher than the upper surface of the lower portion of the other end of the flexible endless belt portion, so that the holder portion 618 can close the other end of the flexible endless belt portion.

In this way, by providing the mounting portion 651 and the holder portion 618, foreign matter can be effectively prevented from entering the inside of the flexible endless belt portion.

More preferably, in some implementations, the upper edge of the mounting portion 651 may be located below the lower surface of the upper portion of one end of the flexible annular band portion, and the one end of the flexible annular band portion is closed by the engagement of the mounting portion 651 with the lower edge of the upper housing 670.

Accordingly, the upper edge of the bracket portion 618 may also be located below the lower surface of the upper portion of the other end of the flexible annular band portion, and the other end of the flexible annular band portion is closed by the engagement of the bracket portion 618 with the lower edge of the upper case 670.
