[0001] Cross-references to related applications

[0002] This application claims priority to Hong Kong Application No. 22020002067.9, filed on January 30, 2020, entitled “OUTDOOR SURFACE CLEANING APPARATUS WITH SPRAY MECHANISM”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure generally relates to an outdoor surface cleaning device. More specifically, this disclosure relates to an outdoor cleaning apparatus having a spray mechanism for discharging a mixed fluid (such as water mixed with a cleaning solution). Background Technology

[0004] Outdoor surface cleaning equipment is a special category of outdoor products designed to handle outdoor surfaces that are more uneven and less refined than indoor surfaces, such as patio or paved surfaces and seams. These outdoor surfaces and seams can be stained with stubborn dirt, weeds, and / or grease that are more difficult to remove than those on indoor surfaces.

[0005] Manually operated paving push brooms and electric pressure washers are examples of conventional outdoor surface cleaning equipment. Paving push brooms generally consist of a fixed brush with stiff bristles arranged at the end of the broom handle. Dirt on the surface can be removed by scrubbing the surface using the bristles (optionally, using cleaning liquid or powder that is manually applied to the outdoor surface before cleaning). Pressure washers, on the other hand, generally consist of a nozzle that directs pressurized liquid to the surface to remove dirt and grease. These conventional outdoor surface cleaning devices are typically specialized outdoor equipment designed specifically for outdoor cleaning operations. These devices are not easily adaptable to different surface cleaning applications.

[0006] Some recently developed outdoor surface cleaning equipment includes one or more scrubbing elements and a water outlet. However, the water discharge mechanism typically only discharges water in one direction to the front of the equipment. The power head (e.g., a motor) and drive element may not be adequately isolated to prevent contact with some of the water discharged during cleaning. Because the power head and gearbox may not be waterproof, water may come into contact with the power head and / or drive element, causing damage to the power head or gearbox over time. Furthermore, while conventional outdoor surface cleaning equipment may effectively clean floors, it may not be effective at cleaning wall surfaces or stair risers. Summary of the Invention

[0007] This document provides a surface cleaning device having a spraying mechanism suitable for spraying different types of liquids. For example, the disclosed cleaning device can be configured to spray mixtures of different liquids, such as water mixed with a concentrated cleaning solution or water alone. The cleaning solution can be sprayed from the surface cleaning device such that it is sprayed directly onto the surface to be cleaned by the surface cleaning device (e.g., a patio or floor), rather than onto a portion of the cleaning device (e.g., cleaning brush bristles). By providing the ability to spray mixed liquids, the surface cleaning device can achieve improved cleaning, which may include removing more dirt or other undesirable substances from the surface and / or removing dirt or other undesirable substances more quickly. Moreover, the ability to spray water alone can also provide additional capabilities, such as the ability to operate the surface cleaning device during a first cleaning cycle, in which water mixed with a concentrated cleaning agent is used, and then a second cleaning cycle can be performed in which only water is dispensed to remove excess cleaning solution that may remain on the surface after cleaning or for other reasons. Additionally, the surface cleaning device constructed according to aspects of this disclosure can also operate without dispensing any liquid (i.e., dry operation mode).

[0008] According to some aspects, the surface cleaning device may include: a handle; a power head with a prime mover; an attachment with cleaning attachments; and a spraying mechanism having a first fluid inlet, a second fluid inlet, and a cleaning fluid outlet. The spraying mechanism may include a mixing assembly in fluid communication with the first fluid inlet, the second fluid inlet, and the cleaning fluid outlet.

[0009] According to some aspects, the cleaning fluid dispensing section may include at least a brush nozzle and a side nozzle. The brush nozzle is configured to spray cleaning fluid onto a surface in front of the cleaning attachment or directly onto the cleaning attachment; and the side nozzle is configured to spray cleaning fluid onto a surface in front of the cleaning attachment or an adjacent surface.

[0010] According to some aspects, the cleaning fluid dispensing section includes at least a dispensing rod having holes arranged horizontally along the longitudinal length of the dispensing rod to dispense cleaning fluid onto the surface to be cleaned by the cleaning attachment.

[0011] In some respects, the first fluid inlet is a water inlet assembly and may include a hose base and a control panel. The control panel may include a controller configured to control the output of liquid during operation of the surface cleaning equipment. For example, the controller may include a joystick, switch, or a constructible (e.g., rotatable, sliding, etc.) knob for selecting between a waterless operation mode, a water-only operation mode, or a detergent-diluted operation mode, in which water is dispensed in the detergent-diluted operation mode to be mixed with cleaning fluid or detergent.

[0012] Depending on some aspects, the hybrid assembly is positioned at the handle. Alternatively, the hybrid assembly may be positioned elsewhere than the handle, such as on a housing attached to a longitudinal axis, wherein the handle is located at a first end of the longitudinal axis, and the housing may be positioned along the length of the longitudinal axis.

[0013] According to some aspects, the second fluid inlet further includes a detergent base configured to attach a detergent bottle or fluid tank. Detergent or concentrated cleaning solution can be stored in the detergent bottle of the fluid tank.

[0014] In some respects, the mixing assembly is positioned along the tubing assembly, which is disposed between the handle and the power head. The mixing assembly may include an integrated canister arranged in a straight line with the tubing assembly. A transparent window with a volume indicator may be provided on the wall of the integrated canister, and a hinged cap and stopper may be provided on the top or side of the integrated canister, allowing the canister to be filled with detergent or cleaning fluid.

[0015] According to some aspects, the mixing assembly further includes a venturi tube having a constriction section, a diffusion section, and a throat section. The constriction section may be coupled to a first hose connected to a first fluid inlet. The diffusion section is coupled to a second hose connected to a cleaning fluid outlet, and the throat section is configured to draw detergent from the second fluid inlet using the Venturi effect, thereby mixing the water flowing through the venturi tube with the detergent to obtain a mixed fluid (e.g., diluted detergent or cleaning solution).

[0016] Depending on some aspects, the second hose has an inner diameter in the range of 7 mm to 12 mm and an outer diameter in the range of 10.5 mm to 16 mm.

[0017] Depending on certain aspects, the control panel may include a valve and two outlet ports. The first outlet port may be connected to the first inlet port of the Y-connector for water delivery, and the second outlet port may be connected to the second inlet port of the Y-connector via a venturi tube and a check valve.

[0018] In some respects, the cleaning attachment is at least partially covered by a shroud disposed between the left-hand and right-hand ends of the power head. The shroud is attached to a rubber scraper that extends from the rear of the shroud, and the height of the shroud is adjustable for controlling the flow of cleaning fluid on the surface.

[0019] In some respects, the surface cleaning equipment further includes a knob for adjusting the flow rate of the cleaning fluid.

[0020] According to some aspects, the surface cleaning device further includes a side brush that can be attached to a side of the cleaning attachment perpendicular to the axis of rotation of the cleaning attachment, thereby allowing the side brush to clean a second surface in a lateral direction, such as a portion of a wall or staircase perpendicular to the surface on which the outdoor cleaning device is placed.

[0021] Depending on some aspects, the cleaning attachment may include a brush head and a circular side brush that can be attached to the brush head. The cleaning attachment may be coupled to a power head to transmit torque, such that the circular side brush allows for lateral brushing of surfaces, such as a section of a wall or staircase perpendicular to the surface on which the outdoor cleaning equipment is placed.

[0022] According to some aspects, the cleaning attachment includes a brush head and a dome-shaped brush that can be attached to the brush head, the dome-shaped brush being coupled to a power head to transmit torque, such that the dome-shaped brush allows for lateral brushing of surfaces, such as a section of a wall or staircase perpendicular to the surface on which the outdoor cleaning equipment is placed.

[0023] According to some aspects, the dome-shaped brush further includes: an inner dome; a plurality of bristles arranged circumferentially around the inner dome; and a ball supported by a recess mounted on the top of the inner dome.

[0024] According to some aspects, the surface cleaning equipment further includes a rotatable joint, wherein the power head and the auxiliary joint, which are in a horizontal position, can be rotated 90 degrees clockwise to a vertical position using the rotatable joint.

[0025] In some respects, the brush head includes removable side brushes. Removable side brushes can facilitate cleaning surfaces that are otherwise difficult to clean, such as stairs.

[0026] On one hand, a drive mechanism can be provided. The drive mechanism may include a motor for generating driving force and a mechanism for transmitting that driving force to the brush head. For example, the mechanism for transmitting the driving force may include a gear chain or may include gears and shafts. The gear chain or gears and shafts allow the drive mechanism to move further from the brush head and reach a position where the possibility of the motor being damaged by fluid splashes is minimized.

[0027] In some aspects, multiple nozzles are arranged to spray fluid onto the surface to be cleaned. The multiple nozzles may be positioned on a shroud or cover that at least partially surrounds the brush head. The shroud may be a multi-piece shroud formed by an inner cover and an outer cover. The inner cover may have multiple recesses that, when covered by the outer cover, form fluid channels. These fluid channels can be used to deliver fluid to the multiple nozzles, at which the fluid is sprayed onto the surface to be cleaned.

[0030] Those skilled in the art will understand that the elements in the accompanying drawings are shown for simplicity and clarity and are not necessarily depicted to scale. Detailed Implementation

[0031] The following detailed description is exemplary in nature only and is not intended to limit the scope of this disclosure or its application and / or use. It should be understood that numerous variations exist. The detailed description will enable those skilled in the art to implement exemplary embodiments of this disclosure without excessive experimentation, and it should be understood that various changes or modifications can be made to the functionality and structure described in the exemplary embodiments without departing from the scope of this disclosure as set forth in the appended claims.

[0032] refer to Figures 1 to 3 The image illustrates an outdoor surface cleaning device 100 in a first configuration according to certain embodiments. The device 100 includes a handle 102 at a rear end 100A, and a power head 104 and attachments at a front end 100B. A tube assembly 106 is arranged between the handle 102 and the power head 104. The tube assembly 106 defines a longitudinal axis A along which the device 100 generally extends. In some embodiments, the tube assembly 106 is an elongated tube assembly formed by an inner tube 106A and an outer tube 106B in a slidably arranged configuration, with a clamp 106C between the inner and outer tubes for locking the inner tube 106A and the outer tube 106B relative to each other. In other words, the tube assembly 106 is a telescopic tube assembly whose length is adjustable to accommodate different user heights. In the first configuration, a first fluid inlet and a second fluid inlet are positioned at the handle 102 for receiving water and detergent, respectively. Device 100 includes an attachment having a brush head 105, which serves as a cleaning attachment. In such cases... Figure 14 In the second configuration shown, device 100 may include: a first fluid inlet positioned at handle 102 for receiving water; and a second fluid inlet positioned along pipe assembly 106 for receiving detergent. Figure 24 The third configuration shown is similar to the second configuration, but device 100 includes an attachment having a disc brush assembly 400, which serves as a cleaning attachment. In such a configuration... Figure 27 In the fourth configuration shown, a circular side brush 522 or a dome-shaped brush 523 can be attached to the device 100.

[0033] In some embodiments, the power head 104 includes a long shaft B that extends generally horizontally and perpendicular to the longitudinal axis A of the tube assembly 106. The power head 104 includes a motor and a gear drive. The motor is arranged to have an axis generally oriented horizontally along the long shaft B. In some embodiments, the attachment has a brush head 105 that includes a roller brush 502 as a cleaning attachment. The brush head 105 may be arranged below the power head 104, and the roller brush 502 is driven to rotate by the power head 104. In some examples, the roller brush 502 may advantageously include (e.g., alternatively along one or both of the circumferential surface or the long shaft of the roller brush 502) bristles arranged in different patterns, these bristles having different lengths, diameters, materials, and / or stiffness to provide improved cleaning results.

[0034] like Figure 2As shown, the handle 102 includes a handle portion 102G that extends generally rearward relative to the tube assembly 106 and the power head 104. The handle portion 102G includes a trigger 108 and a speed control switch 102A. In some embodiments, the handle 102 further includes a forward / reverse button for switching the rotation direction of the roller brush 502. The base portion of the handle portion 102G (i.e., the rearmost part of the handle 102) may include a base 103B having a battery holder for receiving a battery 103. The battery 103 may be a single battery, a battery pack, or other form factor. The battery 103 is mounted above the hose slot 322 of the water inlet assembly 320, which minimizes the risk of cleaning fluid immersion in the battery. As used herein, the term "cleaning fluid" may include water, detergent, diluted detergent, alcohol, and other cleaning solvents. Electrical connections are arranged within the handle 102, tube assembly 106, and power head 104 for electrically connecting the battery 103 to a motor in the power head 104. Device 100 is preferably a cordless DC motor, but alternatively it can be a wired AC motor or a hybrid AC-DC motor. Device 100 can be operated using any number of battery packs 103. In one example, device 100 operates using an 18 V lithium-based battery pack. The base portion 102B defines a plane that is generally at an angle relative to a vertical plane. Actuating the trigger 108 in the handle 102 starts the motor in the power head 104, and thus drives the brush head 105 to rotate. The speed control switch 102A can adjust the rotational speed of the roller brush 502, and the same switch or alternatively, a separate control switch can be used to reverse the rotation direction of the roller brush 502.

[0035] like Figure 3 As shown, an auxiliary handle 110 is mounted to the tube assembly 106 at a position between the clamp 106C and the handle 102. In some embodiments, the position of the auxiliary handle 110 may be adjustable along the tube assembly 106 or otherwise fixed to the tube assembly. The auxiliary handle 110 is mounted to the tube assembly 106 using a U-shaped connector 112 that surrounds the tube 106A and defines an opening for receiving the connecting portion of the auxiliary handle 110. The connecting portions of the U-shaped connector 112 and the auxiliary handle 110 include correspondingly aligned through openings through which a knob 114 extends. A nut 116 is used to tighten the opening of the U-shaped connector 112 to clamp onto and secure the auxiliary handle 110. The auxiliary handle 110 is rotatable relative to the tube assembly 106 about a rotation axis C (defined by the knob 114), which is substantially transverse to the longitudinal axis A of the tube assembly 106.

[0036] Figure 4 It shows Figure 1The device 100 has a front end 100B. The power head 104 includes two lateral end portions 104A and 104B, each of which can be arranged to be directly or indirectly connected to an attachment having a cleaning attachment. In a first configuration, the attachment may include a brush head 105, which is indirectly connected to the power head 104 via a drive assembly 500. The drive assembly 500 is arranged to transmit torque from the power head 104 to the attachment, which is the brush head 105 serving as a cleaning attachment. One of the lateral end portions 104A and 104B allows mechanical connection between the drive assembly in the power head 104 and the drive assembly 500, while the other lateral end portion 104A and 104B can be covered by a side cover 430. Each of the end portions 104A and 104B includes an engagement arrangement for releasably engaging with a corresponding engagement arrangement of the drive assembly 500 or the side cover 430, which can be attached to or detached from the engagement arrangement with or without tools. If the drive assembly 500 engages with the right side of the power head 104, the shaft from the drive assembly is arranged to extend horizontally outward from the left side toward end portion 104A, and the side cover 430 engages with the left side of the power head 104. In other words, the left-side end portion 104A includes a connecting member arranged to engage with a corresponding connecting member of the drive assembly 500. The drive assembly in the power head 104 is arranged to engage with the drive assembly 500, and the lower portion of the drive assembly 500 is connected to a first end of the brush head 105 for driving the roller brush 502 in the brush head 105.

[0037] Viewed from the front of device 100, the power head 104 can be covered by a housing 431 having a plurality of ventilation openings 434. The plurality of ventilation openings 434 are characterized by preventing water ingress and ensuring ventilation to avoid overheating of the power head 104. Specifically, each of the plurality of ventilation openings 434 is a gap suitably arranged on the housing 431 for air intake, the gap extending horizontally toward the center line of symmetry of the power head 104. In some embodiments, the ventilation openings 434 are at least partially covered by a cap or waterproof cover.

[0038] Figure 5 The internal structure of the front end 100B of the device 100 is shown. The drive assembly of the power head 104 can include any type of prime mover, preferably a motor 201 with a geared transmission unit. The power head 104 includes a coupling member for connection with a corresponding coupling member on the transmission assembly 500. The drive assembly of the power head 104 can be oriented in different ways; for example, the motor shaft 201A extends at an angle to the horizontal direction, or even extends vertically. In some embodiments, along with the mechanical connection, an electrical connection can also be established between the drive assembly of the power head 104 and the transmission assembly 500.

[0039] like Figure 4 and Figure 5 As shown, viewed from the front of device 100, the first end cap 432 of transmission assembly 500 is connected to the left-side end 104A of power head 104, and the second end cap 433 of side cap 430 is connected to the right-side end 104B of power head 104. To connect the first end cap 432 of transmission assembly 500 to power head 104, the user simply aligns the corresponding engagement features 506A, 506B on power head 104 with the first end cap 432 of transmission assembly 500, and then moves the first end cap 432 or power head 104 relative to each other along the movement axis D, causing engagement features 506A, 506B to engage. In this embodiment, the movement axis D is generally horizontal. To disconnect the first end cap 432 of the transmission assembly 500 from the power head 104, the user simply disengages the engagement feature 506A on the power head 104 from the engagement feature 506B on the first end cap 432 of the transmission assembly 500, and then moves either the first end cap 432 or the power head 104 away from each other along the movement axis D. The same engagement features 506A and 506B are also provided in the second end cap 433 for connection with the power head 104. The shape and form of the engagement features 506A and 506B can vary, and the number of engagement features 506A and 506B can be any, preferably less than four on each side.

[0040] like Figure 6 As shown, the left-side end 104A and the right-side end 104B extend downwards from the power head 104 to the brush head 105. A cover 512 is screwed between the left-side end 104A and the right-side end 104B, at least partially covering the brush head 105. The shape and form of the cover 512 can vary, but the cover 512 can generally be any type of cover that at least partially surrounds the brush head 105 to protect the power head 104 from material that may be detached from the surface due to the agitation of the brush head 105. Some embodiments also allow the cover 512 to be adjusted without the need for tools. This arrangement further improves the ease of use of the device 100. The engagement and rotation mechanism of the cover 512 can indicate the movement of the cover 512 by a clicking sound (through material contact). The shield 512 may include two rollers 540A and 540B, both of which extend generally parallel to axis D and are generally tapered toward brush 502 to engage corresponding recesses 502R in brush 502 (e.g., Figure 7(As shown). In this embodiment, the roller brush 502 includes radially extending bristles. A rubber scraper 513 is attached to and extends from the rear side of a shield 512, the height of which is adjustable to control the flow of cleaning fluid on the floor surface. Rollers 540A and 540B are mounted on a left drive shaft 501A and a right drive shaft 501B, respectively, which are rotatable along an axis generally parallel to axis D and extend along through openings on the left-side and right-side ends 104A and 104B, respectively. Using O-rings 503A and 503B, nuts 552 and 553 are used to tighten the left-side and right-side ends 104A and 104B, respectively.

[0041] Some embodiments of the internal structure of the power head 104 are in Figures 6 to 8 As shown in the diagram. Motor 201 is secured by motor mounting 202 and motor housing 203 to ensure the position of motor 201 relative to housing 431 of power head 104. Motor 201 may be an electric brushed motor, and when motor 201 is started, motor shaft 201A is driven to rotate. One side of motor housing 203 engages with motor 201, and the other side engages with first planetary carrier 210. A gear transmission unit driven by motor shaft 201A of motor 201 includes a plurality of gears disposed within gearbox housing 204. The plurality of gears are arranged to form a first layer of planetary gears 211 and a second layer of planetary gears 221. The first layer of planetary gears 211 is fixedly connected to the first planetary carrier 210 and engages with a first ring gear 212 to form a first gear arrangement 231. The first gear arrangement 231 is driven by motor 201 and drives the second gear arrangement 232. The second gear arrangement 232 includes a second gear ring 222, a second-layer planetary gear 221, and a hub gear 223 concentric with a washer 205, which engages with the first-layer planetary gear 211 of the first gear arrangement 231. The hub gear 223 drives the second-layer planetary gear 221, which engages with the second gear ring 222. A first bearing 206 is disposed within the gearbox housing 204 and contacts the second-layer planetary gear 221. A drive shaft 514 is mounted in an O-ring 207 and is driven by the second gear arrangement 232 to drive the transmission assembly 500.

[0042] like Figures 7 to 9As shown, one end of the drive shaft 514 includes a main shaft 514A, which is arranged to engage with a corresponding gear in the second gear arrangement 232. The other end of the drive shaft 514 has one or more notches that are fixedly connected to an upper pulley 550 in the upper portion of the transmission assembly 500. The upper pulley 550 is secured in place using a nut 551. A belt drive mechanism is arranged in the transmission assembly 500. The belt drive mechanism is formed by the upper pulley 550 connected to one end of the drive shaft 514, a corresponding lower pulley 504 in the lower portion of the transmission assembly 500, and a belt 554 connecting the two pulleys 550 and 504. The lower portion of the transmission assembly 500 is mechanically connected to a first end of the brush head 105. The lower pulley 504, concentric with the roller brush 502, is arranged to rotatably drive the roller brush 502 at a speed determined by the speed of the motor 201 via the first gear arrangement 231 and the second gear arrangement 232. In some embodiments, belt 554 is a flat belt. Pulleys 550 and 504 may each include axial ribs. Spindle 514A is arranged to allow torque to be transmitted from second gear arrangement 232 to drive shaft 514, and drive shaft 514 is coupled to upper pulley 550, so torque is transmitted via belt 554 to lower pulley 504 to drive brush 502 to rotate. Figure 10 An end cap 432 that can be assembled to cover the drive assembly 500 is shown. In this embodiment, the roller brush 502 is arranged to interact with an outdoor surface to be cleaned or being cleaned. The drive assembly and drive assembly 500 in the power head 104 are configured to rotate the roller brush 502 at a desired speed.

[0043] In some embodiments, the outdoor surface cleaning device 100 can be used as a patio cleaner, which has a spraying mechanism at a front end 100B with a cleaning fluid output section capable of spraying cleaning fluid for cleaning purposes. The cleaning fluid output section may be in fluid communication with a first fluid inlet for receiving water from an external water pipe (such as a garden hose), and there is no built-in water tank. The cleaning fluid output section may also be in fluid communication with a second fluid inlet for receiving detergent. Figure 11A first configuration of the device 100 is shown, illustrating how the cleaning fluid is discharged. A hose 312 is the external tube for delivering the cleaning fluid, which is dispensed to side nozzles 301 and brush nozzles 302. The hose 312 may have an inner diameter ranging from 5 mm to 15 mm, or from 7 mm to 12 mm. The outer diameter of the hose 312 may range from 9 mm to 18 mm, or from 10.5 mm to 16 mm. In some embodiments, the hose has an inner diameter of 7 mm and an outer diameter of 10.5 mm, with a water flow rate of 0.35 L / s and a detergent dilution (a mixture of water and detergent) flow rate of 0.14 L / s. The brush nozzle 302 is a sprayer that may be positioned outside the housing 512, or alternatively inside the housing 512, and above cleaning attachments (such as brush head 105). The brush nozzle 302 is configured to spray cleaning fluid onto a surface in front of the cleaning attachment or directly onto the cleaning attachment. The side nozzle 301 may not be securely fixed to the front end 100B, and the angle of the water sprayed from the side nozzle 301 is adjustable. The side nozzle 301 is configured to spray cleaning fluid onto a contact surface or adjacent surface in front of the cleaning attachment (e.g., brush head 105), such that the cleaning fluid can be discharged onto the surface before contacting the cleaning attachment.

[0044] The spraying mechanism may further include a mixing assembly 330 and a water inlet assembly 320. For example... Figure 12 As shown, the rear end 100A of the device 100 includes a battery 103, a handle 102, a mixing assembly 330, and a water inlet assembly 320. The bottom of the handle 102 is connected to the mixing assembly 300 and the water inlet assembly 320. Both the mixing assembly 330 and the water inlet assembly 320 are encapsulated within a housing 323. At one end of the housing 323, the water inlet assembly 320 is provided as a first fluid input, which includes a hose base 322 and a control panel 324. The hose base 322 is a quick-release base and is connected to the control panel 324, which is configured to connect to and receive an external water pipe. The control panel has a valve for controlling the water input and detergent mixing. The mixing assembly 300 and a second fluid input including a detergent base 321 are located on the bottom side of the housing 323, and the mixing assembly and the second fluid input are in fluid communication with the first fluid input for mixing water from the external water pipe with detergent from the second fluid input. The output of the mixing assembly 300 is in fluid communication with the cleaning fluid output. A detergent base 321 is configured to attach a detergent bottle 350 thereto. A straw 333 extends from the detergent base 321 and into the detergent bottle 350, with its end at the bottom of the bottle for receiving detergent. Figure 13An exemplary embodiment of the water inlet assembly 320 is depicted. The hose base 322 is directly connected to the control panel 324, allowing control of the amount of water entering the mixing assembly 300 from an external water pipe. The control panel 324 includes a joystick 324D, which is rotatable along the circumference of the control panel 324 for selecting an operating mode. When the joystick 324D is set to the center position 324B, the valve of the hose base 322 is closed, and a waterless mode is selected. When the joystick 324D is rotated to the "W" position 324C to select the water-only mode, the valve of the hose base 322 is opened, and only water flows into the mixing assembly 300 to be discharged at the side nozzle 301 and brush nozzle 302. When the joystick 324D is rotated downwards to the "W+D" position 324A to select the detergent dilution mode, the valves of the hose base 322 and detergent base 321 are opened, allowing water and detergent to mix in the mixing assembly 300. The diluted detergent is dispensed via side nozzle 301 and brush nozzle 302. In some embodiments, the control panel 324 may be electrically powered, and the joystick 324D may be replaced by one or more electrically powered switches.

[0045] Figure 14 An outdoor surface cleaning device 100 in a second configuration is shown, comprising a detergent base 321 and a corresponding mixing assembly 330 positioned along a pipe assembly 106, and a water inlet assembly 320 positioned at the front portion of a handle 102. A first fluid inlet is positioned at the handle 102 for receiving water from an external water pipe, while a second fluid inlet, including the detergent base 321, is positioned along the pipe assembly 106 for receiving detergent. At the first fluid inlet, the hose base 322 of the water inlet assembly 320 is in fluid communication with a control panel 324, and both the hose base and the control panel are enclosed within a housing 323, such as... Figure 15 See below for more details.

[0046] In some embodiments, the physical positions of the battery 103 and the water inlet assembly 320 can be interchanged, such as... Figure 16 An alternative configuration of the device 100 is shown. The base portion of the handle portion 102G (i.e., the rearmost part of the handle 102) is connected to the water inlet assembly 320. The front portion of the handle 102 (i.e., the portion opposite to the handle portion 102G) includes a base 103B with a battery holder for receiving the battery pack 103. The battery 103 can be encapsulated in a waterproof battery cover, such as IPX5 or IPX6, because the hose 312 for delivering water from the water inlet assembly 320 can travel within the handle 102 near the battery 103.

[0047] Figure 17An exploded view of the mixing assembly 330 and a second fluid inlet positioned along the tubing assembly 106 of the device 100 is shown. A detergent mount 106D is detachably mounted to the tubing assembly 106. In some embodiments, the detergent mount 106D is fastened to the tubing assembly 106 at the same location as a clamp 106C. The mixing assembly 330, mounted on the detergent mount 106D, includes a venturi tube 340 having a constriction section 340A, a diffusion section 340B, and a throat section 340C. The constriction section 340A is connected to a first hose in fluid communication with the inlet assembly 320 and can be concealed within the hollow interior of the inner tube 106A. The diffusion section 340B is connected to a second hose in fluid communication with a cleaning fluid outlet at the front end 100B for discharging cleaning fluid. The second hose can be concealed within the outer tube 106B. Diffusion section 340B can be used with check valve 341 ( Figure 17 (Not shown) A check valve may be connected or included. The Venturi tube 340 utilizes the Venturi effect to draw detergent out of the detergent bottle 350 and mixes the detergent with water flowing through the Venturi tube 340 via the throat section 340C. The throat section 340C is connected to the connector 327 and the straw holder 325. A spring 326 is also provided within the detergent base 321 such that the straw 333 can be released from the straw holder 325 by pressing the detergent base 321 against the detergent mount 106D.

[0048] Figure 18 and Figure 19 Two configurations of the mixing assembly 330 are shown, which uses an integrated tank 331 arranged in a straight line with the outer tube 106B of the tube assembly 106. A transparent window with a volume indicator is provided on the wall of the integrated tank 331. The first configuration of the mixing assembly 330 is shown below. Figure 18 As depicted, a hinged cap and stopper 332A are located at the top of the integrated tank 331. Detergent is refilled into the integrated tank 331 through opening 334A, and the detergent is drawn out of the integrated tank 331 via a straw 333 through the Venturi effect. Figure 19 In the second configuration of the mixing assembly 330 shown, the hinged cap and stopper 332B are located on the front side. The opening 334B is also located on the front side. In both configurations, detergent is poured into the integrated container 331, and there are no limitations on the compatibility of the detergent bottle 350 for attachment to the detergent base 321.

[0049] In some embodiments, without departing from the spirit of this disclosure, the mixing of detergent and water can also be achieved using gravity or a pump. For example, a connecting tube can be arranged at the bottom of the detergent bottle 350 or integrated tank 331, allowing the detergent to flow downwards by gravity to mix with water using a Y-connector. In another example, a pumping mechanism is provided to draw detergent out of the detergent bottle 350 or integrated tank 331 via a suction tube 333. The pumping power is adjustable to control the desired detergent dosage. The pumped detergent is then mixed with water using a Y-connector.

[0050] Figure 20 It shows in Figure 1 The first configuration of the spraying mechanism at the front end 100B of the device 100. The hose 312 is an external tube for conveying cleaning fluid, which is distributed to the side nozzle 301 and the brush nozzle 302. The brush nozzle 302 is configured to spray the cleaning fluid onto a surface in front of the roller brush 502 or directly onto the roller brush 502. The side nozzle 301 is configured to spray the cleaning fluid onto the contact surface of the roller brush 502 or an adjacent surface of the roller brush 502, such that the cleaning fluid can be discharged from the surface before contacting the roller brush 502.

[0051] Figure 21 A second configuration of the spray mechanism at the front end 100B of the device 100 is shown. A water pipe 313 and a detergent dilution hose 314 are used to deliver water and dilute detergent, respectively, which are then dispensed to a discharge bar 303. Both the water pipe 313 and the detergent dilution hose 314 are concealed within the pipe assembly 106. The discharge bar 303 has orifices arranged horizontally along its longitudinal length, allowing cleaning fluid to be discharged into the roller brush 502.

[0052] Figure 22This is a simplified schematic diagram illustrating the flow of water and detergent within device 100. The hose base 322 is a quick-release base configured to connect to and receive an external water pipe. The hose base 322 is directly connected to control panel 324, which has valves for controlling water input and detergent mixing. Control panel 324 provides two outlet ports 324E and 324F. The first outlet port 324E is connected to the first inlet port of Y-connector 342 for water delivery. The second outlet port 324F is connected to the constriction section 340A of venturi tube 340. Utilizing the Venturi effect, detergent is drawn into venturi tube 340 via throat section 340C, causing the detergent and water to mix to obtain diluted detergent. Diffusion section 340B is connected to check valve 341 and the second inlet port of Y-connector 342 for delivering diluted detergent to front end 100B. When the control panel 324 is switched to "W", water from the hose base 322 is directed to the first outlet port 324E. Therefore, the Y-connector 342 receives the water for discharge. When the control panel 324 is switched to "W+D", water from the hose base 322 is directed to the second outlet port 324F. Therefore, the water mixes with detergent at the venturi tube 340, and the Y-connector 342 receives the diluted detergent for discharge.

[0053] Figure 23 A side brush 521 is shown, which can be attached to one side of the front end 100B, generally perpendicular to the axis of rotation of the roller brush 502. In other words, viewed from the front of the device 100, the side brush 521 is attached to the left-hand end of the drive assembly 500 or the right-hand end of the side cover 430. To attach the side brush 521, the user simply aligns the side brush 521 and the drive assembly 500 or the side cover 430 and moves the side brush 521 or the device 100 toward each other. Velcro can be used to secure the side brush 521. To remove the side brush 521, the user simply pulls the side brush 521 out from either side to separate it from the device 100. The side brush 521 provides a brush for scrubbing wall surfaces or stair rails in a lateral direction.

[0054] Figure 24An outdoor surface cleaning device 100 in a third configuration is shown, comprising a power head 104, a disc brush assembly 400, and a wheel assembly 450. The power head 104 includes two lateral end portions 104A and 104B, each of which can be arranged to directly engage with an attachment having a cleaning attachment. The attachment may include the disc brush assembly 400 as a cleaning attachment. The disc brush assembly 400 is driven by a drive assembly in the power head 104. A cleaning fluid outlet (front nozzle 304) may be provided on the front of the power head 104 for discharging cleaning fluid. The wheel assembly 450 is attached to the right lateral end portion 104B of the power head 104, and the disc brush assembly 400 is attached to the left lateral end portion 104A. Figure 25 As shown, viewed from the front of device 100, the disc brush assembly 400 is coupled to the left end of the power head 104, and the wheel assembly 450 is coupled to the right end of the power head 104. To connect the disc brush assembly 400, the user simply aligns the corresponding engagement features on the power head 104 and the disc brush assembly 400, and then moves the disc brush assembly 400 or the power head 104 toward each other. To disconnect from the disc brush assembly 400, the user simply disengages the engagement features on the power head 104 and the disc brush assembly 400, and then moves the disc brush assembly 400 or the power head 104 away from each other. In some embodiments, the power head 104 is arranged to engage with the disc brush 402 in the disc brush assembly 400 to drive the disc brush 402. The wheel assembly 450 may be mounted in a similar manner, but from the other side of the power head 104, and may or may not have a drive connection between the wheel 451 and the power head 104.

[0055] Figure 26The construction of the disc brush assembly 400 is shown in more detail. The disc brush assembly 400 includes a housing formed by two housing portions 404A and 404B. The first housing portion 404A is used to mount the actuator 406, and the second housing portion 404B is used to mount the disc brush 402. A cover or cap 412 of the disc brush 402 is attached to the second housing portion 404B to which the disc brush 402 is mounted. The two housing portions 404A and 404B define aligned through holes through which a spindle 414 extends. Bearings 420 and 421 are disposed in the housing to support rotation of the spindle 414 about axis E. The spindle 414 includes keyed surfaces 414C and 414C' at both ends. The end 414C of the spindle 414 away from the disc brush 402 is used for connection to a drive shaft 514 in the power head 104. The other end 414C′ of the spindle 414 is used for connection with the disc brush support sleeve 422 (inner flange). This end 414C′ of the spindle 414 also defines an opening for removably (e.g., threadedly) receiving a hexagonal key 426. The spindle 414 is generally long and cylindrical, but 25 has a portion 414O with a relatively flat surface defining an elongated oval cross section. The disc brush 402 is arranged to be mounted on the axially extending cylindrical portion of the support sleeve 422. The outer disc member 424 (outer flange) is arranged on the opposite side of the disc brush 402. The hexagonal key 426 rotatably supports the disc brush 402 between the inner flange 422 and the outer flange 424. A spindle locking mechanism is arranged in the housing. The spindle locking mechanism is formed by a spindle locking button 416 protruding from the housing and a spindle locking plate 428 biased by a compression spring 429A, which is supported by a support flange 429B in the second housing portion 404B. The spindle locking plate 428 defines an opening 428O having upper and lower portions of different sizes. The upper portion is sized to correspond to (e.g., slightly larger than) the short axis of the oblong portion 414O and smaller than the long axis of the oblong portion 414O, while the lower portion is sized to correspond to the long axis of the oblong portion 414O (which is also the diameter of the remaining cylindrical portion). The spindle locking assembly facilitates the replacement or removal of the disc brush 402. To remove the disc brush 402, the user must actuate the spindle locking actuator 416, pressing it so that the upper portion of the opening on the spindle locking plate surrounds the oblong portion 414O. In this way, since the size of the upper portion of the opening 428O is determined to be smaller than the major axis of the oblong portion 414O, the spindle 414 cannot rotate. When the actuator 416 is actuated, the user can engage the hexagonal key 426 with the hexagonal key head 426 and rotate the hexagonal key head to release the hexagonal key head 426 from the spindle 414, thereby removing or replacing the disc brush 402, or the inner flange 422 and the outer flange 424, as needed.

[0056] Figure 27 and Figure 28The front end 100B of an outdoor surface cleaning device 100 in a fourth configuration is shown. This device includes a power head 104, a drive assembly 500, a brush head 105, and a circular side brush 522 or a dome-shaped brush 523. The front end 100B of the device 100 is in a cantilever configuration, so the power head 104 includes only a lateral end portion 104A, which is arranged to be indirectly connected via the drive assembly 500 to an attachment having cleaning attachments (brush head 105 and the attached circular side brush 522 or dome-shaped brush 523). The drive assembly 500 is mechanically coupled to the left lateral end portion 104A of the power head 104 and the brush head 105. A drive assembly in the power head 104 is arranged to be coupled to the drive assembly 500, and the lower portion of the drive assembly 500 is coupled to a first end of the brush head 105 for driving the roller brush 502 in the brush head 105. The device is in a cantilever configuration and has a transmission assembly 500 for connecting the power head 104 and the brush head 105. In some embodiments, the power head 104 may include a knob 436 located on the opposite side of the transmission assembly 500 for adjusting the flow rate of the cleaning fluid. The knob 436 may control a valve on the hose 312, which is configured to control the flow rate from fully open to fully closed. The cleaning fluid outlet may include one or more front nozzles 304 and side nozzles 305. In some embodiments, a nozzle selector 435 may also be provided. The nozzle selector 435 is a slider for selecting between the front nozzle 304 (or brush nozzle 302) and the side nozzle 305.

[0057] refer to Figure 27 A circular side brush 522 is attached to a connecting end 501C on the second end of the brush head 105, which is connected to the right drive shaft 501B for transmitting torque from the transmission assembly 500. Therefore, when the roller brush 502 is driven to rotate by the power head 104, the circular side brush 522 also rotates at the same speed. Unlike existing configurations with a symmetrical design of a left-facing end portion 104A and a right-facing end portion 104B, the fourth configuration has an asymmetrical design of a left-facing end portion 104C and a right-facing end portion 104D. The right-facing end portion 104D has an opening for receiving the shaft of the roller brush 502, allowing the shaft to pass through to receive the circular side brush 522. A bearing is also provided to allow the shaft to rotate relative to the right-facing end portion 104D. The right-facing end portion 104D increases the flexural strength of the roller brush, preventing it from bending towards the power head 104 during use. To connect the circular side brush 522 to the engagement end 501C, the user simply aligns the circular side brush 522 and the engagement end 501C, and then moves the circular side brush 522 or the device 100 toward each other. The engagement of the engagement end 501C and the circular side brush 522 can provide a clicking sound (through material contact) to indicate successful engagement. Reference Figure 28A dome-shaped brush 523 is attached to the second end of the brush head 105, so that when the roller brush 502 rotates, the dome-shaped brush 523 is also driven to rotate by the power head 104. By using the round side brush 522 or the dome-shaped brush 523, the user can easily brush surfaces in a lateral direction, which is particularly useful for cleaning wall surfaces or the vertical slabs 11 of the staircase 10. The round side brush 522 can be a wire brush. The round side brush 522 can also be a disc blade.

[0058] Figure 28 and Figure 29 The diagram shows a torsion head mechanism at the front end 100B of device 100. A rotatable joint 440 can be disposed between the front end 100B and the pipe assembly 106. Figure 28 As shown, viewed from the front of the device 100, the horizontal front end 100B can be rotated 90 degrees clockwise using the rotatable joint 440 to a vertical position, as... Figure 29 As demonstrated. When the front end 100B is twisted, the side nozzle 305 can effectively discharge cleaning fluid to the circular side brush 522 or the dome-shaped brush 523. In some embodiments, the dome-shaped brush 523 further includes: an inner dome; a plurality of bristles 523C arranged circumferentially around the inner dome 523B; and a ball 523A supported by a recess mounted on the top of the inner dome 523B. Figure 30 In the alternative embodiment shown, the socket and ball 523A extend via an arm 523D, which is longer than the bristles 523C, allowing the ball 523A to extend from the center of the inner dome 523B. The dome-shaped brush 523 allows for brushing of lateral surfaces when the device 100 is in a horizontal position, or brushing of horizontal surfaces when the device 100 is in a vertical position.

[0059] The outdoor surface cleaning device 100 can take on different shapes and forms. For example, the outdoor surface cleaning device 100 may include any number of handles 102. The battery holder may be arranged away from the handles 102, for example, on the power head 104. The tubing assembly 106 connecting the handles 102 and the power head 104 may not be adjustable. The clamp 106C may be omitted. The handles 102 do not need to be positioned at the very top of the device 100, nor do they need to extend rearward. The auxiliary handle 110 may be fixedly connected to the tubing assembly 106, or may even be omitted. The auxiliary handle 110 may not be adjustable relative to the tubing assembly 106. The power head 104 may include more than one motor 201. The roller brush 502, the circular side brush 522, or the dome-shaped brush 523 may have different shapes and forms. For example, the roller brush 502 may include any bristle arrangement.

[0060] refer to Figures 31 to 33An aspect of the outdoor cleaning equipment according to an embodiment of this disclosure is shown as an outdoor cleaning device 3100. It should be noted that... Figure 31 A front view of the outdoor cleaning device 3100 is shown. Figure 32 A rear view or back view of the outdoor cleaning device 3100 is shown, and Figure 33 A side view of an outdoor cleaning device 3100 is shown. The outdoor cleaning device 3100 includes: a main body 3102 having a main structure 3108; a first handle 3104; a longitudinal shaft 3106A; a second handle 3110; and a roller brush 3130. Figure 31 and Figure 33 As shown, the longitudinal shaft 3106A can be attached to the body 3102 via an attachment mechanism 3106C. The attachment mechanism 3106C can be configured to engage via a snap-fit ​​(e.g., the attachment mechanism 3106C may include an opening having a groove on its inner surface, and the end of the longitudinal shaft 3106A may include a ridge that snaps into the groove to secure the longitudinal shaft 3106A to the body 3102), a compression fit, and / or a friction fit (e.g., the attachment mechanism 3106C may include an opening with a tapered profile that narrows toward the end of the longitudinal shaft 3106A, such that when the longitudinal shaft 3106A is pressed into the attachment mechanism 3106C and secured in place by compression or friction, the end of the longitudinal shaft 3106A is compressed), or a threaded engagement (i.e., longitudinal...). The end portion of shaft 3106A may have a male thread, while attachment mechanism 3106C may include a female thread, or the end portion of longitudinal shaft 3106A may have a female thread, while attachment mechanism 3106C may include a male thread, a pin (e.g., the ends of attachment mechanism 3106C and longitudinal shaft 3106A may each include two axially aligned openings, such that a pin (e.g., a cotter pin) can be inserted through the first opening of attachment mechanism 3106C, then through the two openings of longitudinal shaft 3106A and out through the other opening of attachment mechanism 3106C), or secured to body 3102 by other techniques (e.g., a clamp (e.g., clamp 106C)).

[0061] like Figures 31 to 33 As shown, the first handle 3104 can be attached to the longitudinal shaft 3106A at the end opposite to the end of the longitudinal shaft 3106A that is attached to the attachment mechanism 3106C. In one aspect, the first handle 3104 may include a design similar to... Figures 1 to 3 , Figure 12 and Figure 16Features of the handle 102, such as an activation mechanism for controlling the operation of the outdoor cleaning device 3100. As described above, the activation mechanism may include a trigger 108, a speed control switch 102A, a forward / reverse button for switching the rotation direction of the roller brush 3130, etc. One difference between the handle 3104 and the handle 102 is that the handle 3104 may not include features for attaching a detergent bottle to the first handle 3104. An auxiliary handle 110 may be attached to the longitudinal axis 3106A, between the first end of the longitudinal axis 3106C (e.g., the end to which the first handle 3104 is attached) and the body 3102. The auxiliary handle 110 may be attached to the longitudinal axis 3106C, as referenced above. Figure 3 As stated above.

[0062] Instead of attaching a detergent bottle to the first handle 3102, the body 3102 can be configured to receive a fluid reservoir 3110. The fluid reservoir 3110 can be configured to store a volume of cleaning fluid, such as detergent or concentrated cleaning solution. In some aspects, the fluid reservoir 3110 can be positioned at the front of the body 3102. Figure 31 ),like Figure 31 and Figure 33 As can be seen in the image. In an additional or alternative manner, the fluid tank can be positioned on the rear side 3204 of the main body 3102, such as... Figure 46 As shown.

[0063] In one aspect, the main body structure 3108 can be formed from body structures 3108A and 3108B. Body structures 3108A and 3108B can be formed from rigid plastic, metal, or other materials and can be fastened together by screws, snap-fits, or other techniques. Body structures 3108A and 3108B can define cavities within the main body structure 3108 to allow for the installation of various control and operational features, such as wiring from the battery to an activation device located on the handle 3104 for activating the outdoor cleaning device 3100, or piping within the main body structure 3108 to establish fluid communication between one or more fluid sources and at least one nozzle of the outdoor cleaning device 3100, as described in more detail below. The main body structure 3108 may include a battery compartment, such as... Figure 31 and Figure 33 As shown, the battery compartment is covered by a battery cover 3120. A battery cover locking mechanism 3122 can be provided to secure the cover in place and protect the battery that provides operating power to the outdoor cleaning device 3100. A locking mechanism similar to the battery cover locking mechanism 3122 can be provided to secure the fluid tank 3110 to the main body, such as... Figure 34 As shown. Brief reference. Figure 34The battery cover 3120 can enclose a battery compartment, in which the battery 3410 can be housed. The battery 3140 can be a battery pack, battery cell, or other type of battery. Once secured within the battery compartment, the battery 3410 can provide operating power to the outdoor cleaning device. The battery cover locking mechanism 3122 can be a latch or clip that snaps shut to secure the battery cover 3120 in place. It should be noted that the use of a latch or clip to secure the battery cover 3120 in place has been described for illustrative purposes and not by way of limitation, and other mechanisms can be used to secure the battery cover 3120 in place according to embodiments of this disclosure.

[0064] On one hand, gaskets or seals formed of soft, waterproof materials (e.g., rubber, silicone, etc.) may be provided on the edge 3422 of the battery cover 3120, or alternatively on the surface of the battery compartment (e.g., the surface in contact with the battery cover 3120), to provide a watertight seal and prevent water or other liquids from entering the battery compartment and potentially damaging the battery 3410 or other electrical components. On another hand, the battery cover 3120 may be secured to the body 3102 via a hinge mechanism. For example, the battery cover 3120 may include two openings 3416, and the body 3102 may include one or more pins 3414 that can be inserted through the openings 3416. Once secured to the body 3102, the battery cover 3120 may be opened by pivoting about the longitudinal axis of the pins(s) 3414 to provide access to the battery compartment and the battery 3410, for example, to remove the battery 3410 for charging on a charging base and to hold the battery 3410 in place before using the outdoor cleaning device 3100. It should be noted that, although Figures 31 to 34 The battery cover 3120 is shown as pivoting upwards, but in some respects, the battery cover 3120 can pivot downwards to expose the battery compartment and battery 3410 (e.g., by switching the positions of the battery cover locking mechanism 3122 and the two openings 3416 located on the battery cover 3120 and one or more pins 3414 connected to the body 3102). Furthermore, in some configurations of the outdoor cleaning device of the embodiments, the battery cover 3120 can also be configured to open to the side rather than upwards or downwards.

[0065] like Figures 31 to 34 As shown, the battery is positioned below the body 3102. Due to its low position near the roller brush 3130, the weight of the battery 3410 may provide a downward force on the roller brush 3130, such as... Figure 33 As indicated by the middle arrow 3302. Powered by battery 3410 ( Figure 34The downward force 3302 provided by the weight of the brush 3130 can enhance its cleaning ability and / or reduce the need for the user to apply downward force to the outdoor cleaning device 3100, thereby simplifying the operation of the outdoor cleaning device 3100. For example, the downward force 3302 can cause the bristles of the brush 3130 to apply greater pressure to the surface being cleaned, and can allow more dirt, grease or other substances to be removed from the surface. The weight of the fluid in the fluid tank 3110 can further increase the downward force 3302; however, the fluid in the fluid tank 3110 will decrease over time as fluid is dispensed during the operation of the outdoor cleaning device 3100.

[0066] like Figure 31 As shown, the brush head 3130 can be positioned at the base of the body 3102. (As indicated...) Figure 32 As shown, the brush head 3130 includes a plurality of bristles 3220. The brush head can be connected via a rotatable joint (e.g., Figures 28 to 29 A rotatable joint 440 or another mechanism (e.g., a ball joint, etc.) is attached to the body 3102. In some aspects, at least one side brush 3140 may be provided. At least one side brush 3140 may be configured to be removably attached to the longitudinal end of the brush head 3130. For example, at least one side brush 3140 may include a shaft 3144, and the longitudinal end of the brush head 3130 may include a container 3210 configured to receive the shaft 3144, such as... Figure 32 As shown. On one hand, release button 3310 (such as...) Figure 33 The brush head 3140 (as shown) can be configured to cover the container 3210 when at least one side brush 3140 is not in use, and to secure at least one side brush 3140 to the brush head 3130, as described in more detail below. A release button 3310 can be adapted to be removably inserted into or attached to the container 3210 through an opening 3204 on at least one side brush 3140. Pressing the release button 3310 removes at least one side brush from the container 3210, thereby providing access to the container 3210 and enabling the insertion of the shaft 3144 of at least one side brush 3140. Figure 32 As shown, at least one side brush 3140 may include a plate 3146 and a plurality of bristles 3142 disposed on a first side of the plate 3146 and extending outward from the plate 3146. A shaft 3144 may be disposed on a second side of the plate 3146 opposite to the first side of the plate 3146 and may extend from the second side of the plate 3146 in an axial direction perpendicular to the surface of the plate 3146. In some aspects, the shaft 3144 and the container 3210 may have a mating form factor. For example, in Figure 32 In the diagram, the shape factor of shaft 3144 is a hexagonal rod, and container 3210 may have a hexagonal opening to receive the hexagonal rod. It should be noted that although in Figure 32The hexagonal shape factor is shown, but this description is provided for illustrative purposes and not as a limitation, and other shape factors, such as square, rectangular, irregular shapes, etc., can be used according to the concepts disclosed herein. In one aspect, at least one side brush 3140 can be secured to the container 3210 via snap-fit, friction fit, compression fit, threaded fit, etc., depending on the specific configuration of the attachment device 3142 and the container 3210. An exemplary embodiment of securing the element to the brush head 3130 using a release button 3310 is described in more detail below.

[0067] like Figure 33 As shown, a hose 3202 can be installed. The hose 3202 can be configured to deliver a first fluid to the outdoor cleaning device 3100. For example, the hose 3202 could be a water hose that brings water to the cleaning device 3100. The body 3102 may include a hose connector or hose slot 322 for connecting the hose 3202 to the body 3102. As described above, the outdoor cleaning device 3100 may include a mixing device for mixing the first fluid supplied by the hose 3202 with a second fluid stored in a fluid tank 3110, shown in illustration 3304. The mixing device may be disposed within the body 3102. In one aspect, the mixing device may be a venturi tube (such as the one referenced above). Figure 22 The described venturi tube can be in fluid communication with hose 3202 via hose slot 322 to allow the fluid delivered by hose 3202 to reach the mixing device. It should be noted that using a venturi tube to provide mixing eliminates the need for a pump, thereby reducing the complexity and cost of manufacturing the outdoor cleaning device 3100 and minimizing the number of parts that may fail during operation. Additionally, the fluid mixing device can be in fluid communication with fluid tank 3120, thereby allowing the mixing device to mix the fluid delivered by hose 3202 with the fluid stored in fluid tank 3120. In various aspects, a mixing controller can be provided to control the mixing of different fluids, such as the fluid stored in fluid tank 3120 and the fluid delivered by hose 3202. In one aspect, the mixing controller may include, as referenced above... Figure 12 , Figure 13 and Figure 15The control panel 324 and joystick 324D are described and shown. The mixing controller also enables the outdoor cleaning device 3100 to discard the mixed fluid, such as dispensing only one fluid (e.g., the fluid delivered by hose 3202, the fluid stored in fluid tank 3120, etc.). In an additional or alternative aspect, the mixing controller also enables the outdoor cleaning device 3100 to operate without dispensing any fluid (i.e., dry operation mode). In other aspects, the mixing controller enables the outdoor cleaning device 3100 to operate while dispensing only the cleaning fluid stored in fluid tank 3120, such as dispensing concentrated cleaning fluid onto surfaces soiled by materials that may be difficult to clean effectively with diluted cleaning fluid. In this scenario, concentrated cleaning fluid may first be dispensed and applied to the soiled surface, and then a diluted mixture of the cleaning fluid and the fluid delivered by hose 3202 can be used to perform final cleaning, or final cleaning may be performed using only the fluid delivered by hose 3202. In this embodiment, fluid tank 3120 may include a first output in fluid communication with the mixing device and a second output in direct communication with at least one nozzle.

[0068] like Figure 33 As shown, the hose 3202 can be secured in place by one or more retaining members 3312. In one aspect, the one or more retaining members 3312 may include straps, hooks, or other components that can be used to secure the hose 3202 in a desired orientation relative to the outdoor cleaning device 3100. In some aspects, the outdoor cleaning device 3100 may include a rubber scraper 513 that can be attached to the lower rear portion of the cover 3150. (Reference) Figures 35 to 38 Exemplary aspects of the shield 3150 are shown and described in more detail.

[0069] refer to Figure 35 Provides examples of nozzle positions Figures 31 to 34 A partial 3D view of the nozzles of an outdoor surface cleaning device. (See image below.) Figure 35 As shown, the shield 3150 may at least partially surround the brush head 3130. Multiple nozzles may be disposed on the shield 3150. The multiple nozzles may include nozzles 3510, 3520, 3530, 3540, and 3550. Each nozzle may be in fluid communication with the output of the mixing device, enabling the nozzle to dispense fluid from the hose 3202 and / or the fluid tank 3120. The multiple nozzles may be configured to directly or indirectly spray fluid onto the surface to be cleaned. For example, as... Figure 35As indicated by the large arrows, nozzles 3520, 3530, and 3540 can spray fluid onto the front of brush head 3130, and nozzles 3510 and 3550 can spray fluid onto the sides of brush head 3130. Alternatively, nozzles 3520, 3530, and 3540 can spray fluid onto the bristles of brush head 3130, or first onto the upper surface of shield 3150 and then onto the bristles of brush head 3130; and nozzles 3510 and 3550 can spray fluid onto the bristles of side brush 3140. In some aspects, some of nozzles 3510, 3520, 3530, 3540, and 3550 can be configured to spray fluid onto the bristles of brush head 3130, while other nozzles 3510, 3520, 3530, 3540, and 3550 can be configured to spray fluid onto the surface to be cleaned. It should be noted that, although Figure 35 Multiple nozzles are shown, including five nozzles (i.e., nozzles 3510, 3520, 3530, 3540, and 3550), but in some embodiments, the outdoor cleaning apparatus according to aspects of this disclosure may include more than five nozzles or fewer than five nozzles. Furthermore, the outdoor cleaning apparatus according to this disclosure may include a single nozzle if desired. Therefore, it should be understood that the outdoor cleaning apparatus constructed according to the embodiments disclosed herein includes at least one nozzle.

[0070] As explained above, the injection of fluid can be controlled via a mixing controller, which can facilitate the selective mixing of different fluids, such as a first fluid delivered by hose 3202 and a second fluid (e.g., from fluid tank 3120) for output via multiple nozzles. In a first configuration, the mixing controller can be configured to control the output of only the first fluid via multiple nozzles; in a second configuration, the mixing controller can be configured to control the output of a mixed fluid (e.g., fluid generated by mixing the first and second fluids) via multiple nozzles; and in a third configuration, the mixing controller can be configured to prevent any fluid output via multiple nozzles (i.e., dry operation or dry operating mode). It should be noted that although three operating modes (i.e., one fluid, two fluids, and no fluid) have been described, outdoor cleaning devices according to embodiments of this disclosure may include mixing controllers capable of operating in more than three modes (e.g., the above-described cleaning fluid dispensing mode) or fewer than three modes (e.g., water-only mode, water and cleaning fluid mixing mode, but no dry mode).

[0071] Figure 36 It shows Figure 35 The additional aspects of the shroud 3150 and multiple nozzles. For example, Figure 36The orientation of nozzle 3150 and how it is pointed (at least partially) towards one side of outdoor cleaning device 3100 are shown. Nozzle 3510 may have a similar orientation to nozzle 3550. Figure 37 As shown, the protective cover 3150 can be formed as a multi-piece protective cover. The multi-piece protective cover may include an inner protective cover 3720 and an outer protective cover 3710. The inner protective cover 3720 and the outer protective cover 3710 together define an internal space therein. See reference... Figure 64 In more detail, the interior space can facilitate the arrangement of other components of the outdoor cleaning apparatus of the embodiment, such as pipes for establishing fluid communication between one or more nozzles and mixing devices and hose slots.

[0072] Additionally, the internal space between the inner cover 3720 and the outer cover 3710 may include additional structures for securing or mounting components of the outdoor cleaning device, such as one or more nozzles, in place. For example, the peripheral edge of the inner cover 3720 may define a recess 3702, and the peripheral edge of the outer cover 3710 may define a recess 3712. The recess 3702 of the inner cover 3720 and the recess 3712 of the outer cover 3710 may be configured to secure multiple nozzles in place. For illustration and reference Figures 65 to 67 A series of images are shown demonstrating the features of securing a nozzle in place using an inner and outer protective cover, according to aspects of this disclosure. Figure 65 As shown, the outer cover 3710 includes a groove 3712, a bracket 6510, and a notch 6512. Similarly, Figure 65 A lower cover 3720 with a groove 3702, a bracket 6520, and a notch 6522 is shown. A nozzle 6530 is shown and includes a shaft 6532, a retaining ring 6534, a barbed connector 6536, an end portion 6538, and an opening 6540. The barbed connector 6536 can be configured to secure a tube (e.g., a tube conveying fluid received from a mixing device or from a hose connected to a hose slot 322) to the nozzle 6530, as referenced below. Figure 64 A more detailed description and demonstration are provided. It should be noted that... Figure 65Nozzle 6530 is shown as including barbed connector 6536 for illustrative purposes and not as a limitation, and other types of connectors (e.g., threaded connectors, quick-connect fittings, etc.) may be used to secure tubing to nozzle 6530 and establish fluid communication between nozzle 6530 and one or more fluid sources. Retaining ring 6534 may be formed as a ridge extending vertically from the outer surface of nozzle 6530 near the end portion 6538. The ridge may be present along the entire outer surface of nozzle 6530, or it may be present only on one side of nozzle 6530 (e.g., the side near notch 6512 or 6522), on two adjacent or opposite sides of nozzle 6530 (e.g., top and bottom, left and right, top side and left, top side and right, bottom side and left, bottom side and right, etc.), or on three sides (e.g., top / bottom / left, top / bottom / right, top / left / right, bottom / left / right, etc.).

[0073] like Figure 66 As shown, the retaining ring 6534 can be configured to rest within recesses 6512 and 6522, and a portion of the shaft 6532 can rest within brackets 6510 and 6520. It should be understood that, as Figures 66 to 67 As shown, when the inner cover 3720 is fixed to the outer cover 3710 to form the cover 3150, the shaft 6532 of the nozzle 6530 can be clamped between the brackets 6510 and 6520, and the retaining ring 6534 can be clamped between the recesses 6512 and 6522. Additionally, the end portion 6538 can be clamped between the grooves 3702 and 3712, such that the nozzle opening 6540 is flush with the outer surface of the inner cover 3720 and the outer cover 3710, slightly extending beyond (e.g., 1 mm, 2 mm, etc.) the outer surface of the inner cover 3720 and the outer cover 3710, or slightly recessed (e.g., 1 mm, etc.) into the interior of the grooves 3702 and 3712. Fixing the nozzle 6530 within the cover 3150 in this manner prevents the nozzle 6530 from moving during operation of the outdoor cleaning device. It should also be noted that although... Figures 65 to 67 The above concept regarding a single nozzle 6530 is illustrated, but the inner shroud 3720 and outer shroud 3710 can be configured as recesses, notches, and brackets of different sizes and shapes to accommodate nozzles of different shapes and sizes, including but not limited to multi-nozzle devices or assemblies (e.g., Figure 38 This includes multi-nozzle devices or components containing nozzles 3820, 3830, 3840, and 3850. (For example...) Figure 67As shown, once in the correct orientation (e.g., retaining rings are positioned in recesses of the inner and outer shrouds, and shafts are positioned on brackets of the inner and outer shrouds), the end portion 6538 can extend to, nearly extend to, or extend beyond the peripheral edge of the cap 3150, thereby allowing the opening 6540 to dispense liquid to be delivered to the nozzle 6530 as described herein.

[0074] It should be noted that the terms “top,” “bottom,” “left,” and “right” are used to indicate the potential locations of (multiple) ridges configured to rest at least partially relative to each other within recesses 6512, 6522. For example, the “bottom” side of nozzle 6530 may be the side located near the inner surface of inner shroud 3720, such that the ridge resting within recess 6522 is located on the “bottom” of nozzle 6530, and the “top” side of nozzle 6530 may be the side located near outer shroud 3710, such that the ridge resting within recess 6512 is located on the “top” of nozzle. Alternatively, the "bottom" side of nozzle 6530 may be a side located near the inner surface of outer cover 3710, such that the ridge resting in recess 6512 is located on the "bottom" of nozzle 6530, and the "top" side of nozzle 6530 may be a side located near inner cover 3720, such that the ridge resting in recess 6522 is located on the "top" of nozzle 6530. It should also be noted that the ridges on one or more "sides" of nozzle 6530 may be configured to prevent nozzle 6530 from sliding back into the internal space between inner cover 3720 and outer cover 3710 as indicated by arrow 6554. For example, "side" ridges may extend outward from the outer surface of nozzle 6530 and are located between ridges 6550, 6552 and the peripheral edge of inner cover 3720. The side ridges of nozzle 6530 may contact ridges 6550, 6552, thereby restricting movement of the nozzle in the direction indicated by arrow 6554. It should be noted that the outer cover 3710 can be similarly configured such that the ridges 6556 and 6558 can similarly restrict the movement of the nozzle 6530 in the direction indicated by the arrow 6554.

[0075] It should be noted that, although the above description (and the following description) Figure 64 The diagram illustrates nozzles that can be connected to pipes to deliver fluid from the fluid branching device 3870 to each nozzle; however, in some respects, these nozzles can be formed via grooves formed on the inner surfaces of the inner shroud 3720 and the outer shroud 3710. See, for example, [reference needed]. Figure 69 Looking down Figure 37 The angle of the length of arrow 3704 (i.e., the inner shroud 3720 viewed from the front) indicates... Figure 37 The internal protective cover 3720. For example... Figure 69As shown, multiple fluid channels 6902 can be formed by grooves provided on the top surface 6922 of the inner cover 3720 and / or the lower surface 6912 of the outer cover 3710. Each nozzle can correspond to one end of one of the fluid channels 6902. Thus, when the outer cover 3710 is fixed to the inner cover 3720, the fluid channels 6902 can form fluid passages for conveying fluid (e.g., the output of a mixing device, a hose slot, etc.), which deliver fluid to the nozzle(s) defined by openings at the ends of the fluid channels, which are formed by grooves provided on the inner cover 3720 and the outer cover 3710. Note that illustration 6910 shows a partial view of the nozzle 3850 viewed from the direction indicated by arrow 6930, which is formed when the inner cover 3720 is fixed to the outer cover 3710. For example, illustration 6910 shows a groove 6940 formed on the upper surface 6922 of the inner cover 3720 and a groove 6950 formed on the lower surface 6912 of the outer cover 3710. In some aspects, the grooves forming the fluid passage may be provided on only one of the covers, rather than on both covers, making the fluid passage smaller, which can provide greater pressure when the fluid exits the nozzle(s). It should be understood that the inner cover 3720 and the outer cover 3710 are shown in illustration 6910 as being separated by a small space in order to emphasize the upper surface 6922 of the inner cover 3720 and the lower surface 6912 of the outer cover 3710, and the inner cover 3720 and the outer cover 3710 may not be separated when the inner cover 3720 and the outer cover 3710 are fixed together to form cover 3150. However, in some respects, the inner cover 3720 and the outer cover 3710 can be configured to provide at least some space between them when they are connected. For example, a gasket or other type of sealing mechanism can be placed between the inner cover 3720 and the outer cover 3710 to ensure that the fluid passage is sealed and to prevent fluid leakage in the internal space between the inner cover 3720 and the outer cover 3710.

[0076] refer to Figure 39This is a partial view of the battery compartment of an outdoor cleaning device according to aspects of this disclosure. As described above, the outdoor cleaning device 3100 may include a battery compartment configured to receive a battery. The outdoor cleaning device 3100 may include a drain hole 3902 within the battery compartment of the main body structure 3108 to allow any liquid that does enter the battery compartment to drain quickly and prevent damage to the battery or other components. The drain hole 3902 may be connected to a drain line that allows for the rapid removal of any accumulated liquid from the battery compartment and minimizes the chance of damage to the battery 3410. For example, the drain line may be configured to allow any collected fluid to exit the outdoor cleaning device 3100 near the cover 3150. Any fluid exiting the drain line can then flow out of the cover 3150.

[0077] It should be noted that a drain hole 3902 can be provided as a supplement or replacement to the aforementioned seal or gasket, which can be provided on the edge of the battery cover 3120 or around the edge of the battery compartment. For example, as Figure 39 As shown at 3906, a channel or recess 3904 is illustrated. The channel 3904 may be formed by portions of the housing 3910 that form the battery compartment (e.g., channel walls 3912 and 3914). The channel 3904 may completely surround the battery compartment. The channel 3904 itself may at least prevent some water from entering the battery compartment. As shown at 3906, a seal or gasket 3908 may be disposed within the channel 3904. The seal or gasket 3908 may be formed of a soft material such as rubber, and when the battery cover 3120 is placed in place (and locked via the battery cover locking mechanism 3122), the battery cover may press against the seal or gasket 3908 to form a waterproof seal around the battery compartment and prevent liquid from entering the battery compartment during operation of the outdoor cleaning device 3100. The seal or gasket 3908 can be formed within the channel 3904 via an overmolding process, wherein a soft material is formed onto the portion of the housing 3910 that forms the channel 3904. Alternatively, the seal or gasket 3908 can be a separate component that can be placed within the channel 3904 and, once secured in place, can be held in place via a compression fit and through the battery cover 3120.

[0078] refer to Figure 40 and Figure 41The diagram illustrates an additional aspect of the fluid tank. The fluid tank 3110 (shown as transparent to reveal its internal structure) may include a drain pipe 4010 that allows fluid to be removed from the fluid tank 3110, for example, via a mixing device or directly delivered via multiple nozzles. In one aspect, the volume of the fluid tank 3110 may correspond to the battery life of the battery 3410, enabling the outdoor cleaning device 3100 to operatively and continuously dispense a mixture of a first fluid (e.g., fluid delivered by hose 3202) and a second fluid (e.g., fluid stored in the fluid tank 3110) until the fluid tank 3110 is empty. In some embodiments, the fluid tank has a volume of 0.3 L to 2 L or 0.5 L to 1 L. Figure 41 As shown, a fluid tank interface can be provided to allow the fluid tank 3110 to be secured to the body 3102. The fluid tank interface may include a recessed region 4114 surrounded by a raised lip 4110. The recessed region 4114 may receive the fluid tank or a portion thereof (e.g., Figure 40 As shown), the raised lip 4110 helps hold the fluid tank 3110 in place during operation of the outdoor cleaning device 3100. A drain hole 4112 may be provided at the base of the recessed area to allow any spilled liquid (e.g., liquid spilled during filling of the fluid tank 3110 or other liquids). Additional mechanisms may also be provided to hold the fluid tank 3110 in place, such as clamping mechanisms (e.g., Figure 34 (Hook and loop fastener 3430).

[0079] refer to Figure 42 This illustration shows aspects of a drive mechanism for providing driving force to a brush head of an outdoor cleaning device, according to aspects of this disclosure. In some embodiments, the drive mechanism may include a motor 4210, a transmission, and a drive shaft 4212. Figure 42 In this device, the transmission mechanism may include a gear chain protected by a cover, which includes a left cover 4220A and a right cover 4220B. Figures 43 to 45 A gear chain drive including multiple gears 4310 is shown. The multiple gears allow the motor 4210 to be positioned at a threshold distance from the brush head 3130. The multiple gears also allow for a greater torque output to the roller brush. For example, multiple gears of the gear chain can span at least the threshold distance, which allows the motor 4210 to be positioned further away from the brush head 3130 to mitigate damage to the motor from backsplashes of fluid ejected from multiple nozzles as the fluid is swept by the bristles of the brush head 3130. Figures 43 to 45In contrast to a gear chain, the drive unit may include a motor 4210 and a gear and shaft drive. The gear and shaft drive may include one or more gears, such as gears 4710 and 4712, and a shaft 4720. Shaft 4720 allows the power or driving force generated by the motor 4210 to be transmitted to the brush head 3130, while allowing the motor 4210 to be located at a greater distance, such as a threshold distance, which prevents damage to the motor 4210 from water splashed from the brush head 3130 during cleaning. In some embodiments, the distance between the connection between the motor 4210 and the drive shaft 4212 and the longitudinal axis of the brush head may be 104 mm. The brush head 3130 may have a radius of 51 mm. In such an embodiment, the threshold distance used to separate the motor 4210 from the brush head 3130 may be 53 mm. It should be noted that when the motor 4210 is separated from the brush head 3130 by a threshold distance and various covers are provided (e.g., inner cover 3720, outer cover 3710, left cover 4220A, and right cover 4220B), the possibility of liquid damage to the motor 4210 and damage to the mechanisms (e.g., drive shaft 4212, gear chain, etc.) used to transmit the power generated by the motor 4210 to the brush head 3130 can be minimized, as referenced below. Figures 63A to 63C In more detail, the outdoor cleaning apparatus constructed in accordance with this disclosure may also be equipped with additional mechanisms.

[0080] refer to Figures 48 to 53 This shows a partial view of an aspect of the brush head 3130. Figure 48 A portion of the 3130 brush head was shown, and more details were provided. Figure 38 One of the roller brush portions 3802 and 3804. Roller brush portions 3802 and 3804 may include a cylindrical member 4810 to which bristles may be attached. It should be noted that a second roller brush may be disposed near the first end 4812 of the cylindrical member 4810. For example... Figure 49 As shown in more detail, the cylindrical member 4810 may be hollow to allow the axial locking member 4830, the rotary locking member 4910, the release button 3310, and the output shaft 4920 to be inserted into the cylindrical member 4810. The output shaft 4920 may be inserted through the rotary locking member 4910 such that the distal end of the output shaft 4920 extends from the distal end 5102 of the rotary locking member 4910, as shown in the diagram. Figure 51 As shown. The portion of the output shaft 4920 extending beyond the distal end 5102 may include a tapered end 5110 and an annular groove 5120. The tapered end 5110 and the annular groove 5120 may be configured to secure the output shaft 4920 to, as shown in the reference. Figures 58 to 64 A more detailed description and illustration of the axial locking member 4830. (See attached image.) Figure 52 As shown, the output shaft 4920 may include, for example: Figure 53The section 5302 shows the D-axis portion 5220 with a flat surface 5210.

[0081] The D-axis portion 5220 can be constructed as follows: Figure 57A The axial extension extends through the D-shaped bore 5702 of the rotary locking member 4910. On one hand, one or more openings 5704 extending perpendicular to the longitudinal axis of the rotary locking member 4910 may be provided. The one or more openings 5704 may be configured to align with openings 5212 on the D-axis portion 5220 of the output shaft 4920. One or more pins or bars (when installed) may be inserted through openings 5212 and 5704 to secure the output shaft 4920 to the rotary locking member 4910. To provide additional structural integrity and enhance the rotational force transmitted to the brush portions 3802, 3804, the rotary locking member 4910 may have a hexagonal form factor 5706, which may be configured to mate with hexagonal openings on the brush portions 3802, 3804, as referenced. Figure 32 As described and shown. It should be noted that the hexagonal openings on the brush portions 3802, 3804 can be located at the first end 4812 of the cylindrical member 4810. The hexagonal shape factor can help lock the rotation locking member 4910 in place and drive the brush portions 3802, 3804 to rotate. Similarly, the hexagonal shape factor also allows the cylindrical member 4810 to transmit rotational force to the axial locking member 4930.

[0082] refer to Figures 54 to 56 An exemplary aspect of the release button according to this disclosure. Figures 54 to 56 middle, Figure 33 The release button 3310 is shown as including a cap 5410, a tab 5412, and a central support 5414. Each tab 5412 may include at least a partially tapered portion 5416. Figure 55 ).like Figure 57B As shown, the release button 3310 can be inserted into the axial locking member 4830, with the tapered portion 5416 of each tab 5412 being inserted first. After insertion, the cap 5410 of the release button 3310 can be positioned flush with the end 5740 of the axial locking member 4830, as... Figure 57D As shown. Alternatively, the cap 5410 of the release button 3310 may be slightly raised (e.g., 1 mm, 2 mm, etc.) or slightly depressed (e.g., 1 mm, 2 mm, etc.) relative to the end 5740 of the axial locking member 4830.

[0083] like Figure 57CAs shown, after insertion, the tapered portion 5416 of the tab 5412 can be positioned near the end 5742 of the axial locking member 4830. The end 5742 of the axial locking member 4830 may include a cavity 5750. A retaining member 5752 can be positioned along the longitudinal axis of the cavity 5750 at the peripheral edge of the cavity 5750. The retaining member 5752 can be configured as a retaining clamp. For example, as... Figures 58 to 60 As shown, a clamp 5800 can be provided. The clamp may include a base 5810 and a base 5820. Conical ridges 5812 and 5814 may be provided on opposite sides of the base 5810, and conical ridges 5822 and 5824 may be provided on opposite sides of the base 5820. Figure 59 As shown in the cross-sectional view, the conical ridge can form valley 5902. Elastic member 5816 can be connected to base 5810, and elastic member 5826 can be connected to base 5820. Elastic members 5816 and 5826 can be configured to bias clamp 5800 onto... Figures 58 to 60 The closed position is shown. On one hand, the elastic members 5816 and 5826 can be as follows: Figures 58 to 62F The leaf spring shown. In additional or alternative aspects, the elastic members 5816 and 5826 can be other types of elastic structures, such as coil springs. Base 5810 may include a recessed portion 6010, and base 5820 may include a recessed portion 6020 (…). Figure 60 The recessed portions 6010 and 6020 can be as follows: Figure 58 and Figure 60 The curve shown may be curved or may have other shape factors (e.g., square, triangle, rectangle, etc.).

[0084] When in Figure 58 and Figure 60 In the closed position shown, the recessed portions 6010, 6020 may define an opening 5830. The opening 5830 may be configured to allow the clamp 5800 to close around the annular groove 5120 of the output shaft 5920; however, the opening 5830 may be smaller than the conical end 5110 of the output shaft 5920 (e.g., the conical end 5110 cannot pass through the opening 5830 unless the clamp 5800 is open). To allow the conical end 5110 to pass through the opening 5830, the clamp 5800 may be positioned as follows: Figure 61 The opening position is shown. To open clamp 5800, it can be done as follows: Figure 62AArrow 6202 indicates pressing the release button 3310. For example, a user operating an outdoor cleaning device can press the release button 3310 to provide downward force. The downward force provided by pressing the release button 3310 may cause the tapered portion 5416 of the tab 5412 to travel into the valley 5902 defined by the opposing tapered ridges 5814, 5824 (and 5812, 5822). When contacting the inclined surface 6204 of the tapered ridges 5814, 5824 (and the inclined surface on the other side of the clamp), the tab 5412 can slide downward along the inclined surface 6204 and separate the base 5810 from the base 5820, as... Figure 62B As shown, this positions the clamp 5800 in the open position. Once in the open position, the conical end 5110 of the output shaft 5920 can pass through the opening 5830, such that the annular groove 5112 is aligned within the opening 5830, and the conical end 5110 is positioned above the bases 5810 and 5820, as... Figure 62F As shown.

[0085] When the downward pressure on the release button 3310 is released, the elastic members 5816 and 5826 can be biased toward each other at their bases 3810 and 3820 and placed in a closed position, thereby fixing the annular groove 5112 within the opening 5830. Figures 62D to 62E As shown. In one aspect, the resilient member 6250 can be positioned around the central support 5414. The resilient member 6250 can be configured to bias the release button 3310 in a non-pressed position, such that when the user stops pressing the release button 3310, the resilient member 6250 causes the release button 3310 to return to its original position. Figure 62C The non-pressed position is shown. On one hand, the elastic member 6250 can be as follows: Figure 62C The spring shown. In additional or alternative aspects, the elastic member 6250 may not be a spring.

[0086] like Figure 62G As shown in the cross-sectional view, the gap 6220 may exist between the release button 3310 and the elbow 6230 of the axial locking member 4830. The elbow 6230 may correspond to the point where the head 6232 of the axial locking member 4830 meets the shaft 6234 of the axial locking member 4830, as shown in the cross-sectional view. Figure 62GThe cross-sectional view is shown. Additionally, a gap 6222 may exist between the end 6240 of the central support 5414 and the conical end 5110. When the release button 3310 is pressed, the elastic member 6250 can compress or deform, thereby allowing the lower surface of the cap 5410 to move toward the upper surface 6236 of the elbow 6230, and allowing the end 6240 of the central support 5414 to move toward the conical end 5110 of the output shaft 4920. Similarly, when the force applied to the release button 3310 is withdrawn, the biasing force of the elastic member 6250 can cause the release button 3310 to move away from the upper surface 6236 of the elbow 6230 and the end 6240 of the central support 5414 to move away from the conical end 5110 of the output shaft 4920, thereby returning the release button 3310 to its normal resting position. In the normal resting position, the cap 5410 is separated from the elbow 6230 through the gap 6220 and the end 6240 is separated from the conical end 5110 through the gap 6222. It should be noted that the release button 3310 and the reference... Figures 62A to 62G The described locking operation can be used to secure the side brush to one or both sides of the brush head, and to close one or more ends of the axial locking member when the side brush(s) are not in use.

[0087] refer to Figures 63A to 63C A partial view is shown illustrating an exemplary aspect of a motor cover for an outdoor cleaning device according to an embodiment of this disclosure. Figures 63A to 63C The image shows a motor cover 6310. The motor cover 6310 can be positioned near the center of the protective cover 3150. (Example...) Figure 63A , Figure 63C As shown, the motor cover can be configured to be at least partially located within the main body structure 3108. For example, the main body structure 3108 can overlap with the upper portion 6312 of the motor cover 6310 (as indicated by arrow 6320). This overlap prevents liquids splashed onto or present on the main body structure 3108 from entering the motor cover and potentially damaging the motor 4210. For example, due to the overlap, any liquid flowing down the outer surface of the main body structure 3108 will fall from the main body structure 3108 and onto the outer surface of the motor cover 6310, where it will then flow downwards onto the cover 3150 and onto the ground. In all respects, the upper portion 6312 and the lower portion of the main body structure 3108 can fit tightly together to prevent liquids from entering the motor cover 6310 and damaging the motor 4210. It should be noted that the motor cover 6310 can be formed of a material such as rubber or silicone, allowing the motor cover 6310 to deform slightly to facilitate a tight fit received by the opening at the lower portion of the main body structure 3108. A tight fit further enhances the protection of the motor 4210 and other drive components from liquid damage.

[0088] refer to Figure 64 The image illustrates an exemplary aspect of controlling the flow rate of a liquid (e.g., a mixed liquid, an unmixed liquid, or no liquid). Figure 64 As shown, the hose slot 322 may include, as referenced Figure 22 The output units 324E and 324F are described above. Output unit 324F can be connected to a mixing device (e.g., via pipe 6402). Figure 22 The mixing device may include a detergent inlet 340A (Venturi tube 340). A detergent inlet 340C may be used to receive detergent from a fluid storage tank 3110 via a pipe 3404. An output 340B of the mixing device may be connected via a pipe 6406 to an inlet 6412 of a fluid branching device 3870 to deliver a mixed fluid (e.g., detergent or cleaning solution mixed with water provided by a hose connected to a hose slot 322) to the fluid branching device 3870, and then to nozzles 3810, 3820, 3830, 3840, 3850, and 3860. The fluid branching device 3870 may include outputs 6420, 6430, 6440, 6450, 6460, and 6470. Output unit 6420 can be connected to nozzle 3810 via pipe 6422, output unit 6430 can be connected to nozzle 3820 via pipe 6432, output unit 6440 can be connected to nozzle 3830 via pipe 6442, output unit 6450 can be connected to nozzle 3840 via pipe 6452, output unit 6460 can be connected to nozzle 3850 via pipe 6462, and output unit 6470 can be connected to nozzle 3860 via pipe 6472. The fluid branching device 3870 can improve the uniform distribution of fluid between nozzles and ensure uniform jet pressure of the fluid leaving the nozzle.

[0089] Additionally, the output 324E of the hose slot 322 can be connected via pipe 6408 to the input 6410 of the fluid branching device 3870 to deliver unmixed fluid to nozzles 3810, 3820, 3830, 3840, 3850, and 3860. As described above, the control panel 324 can also provide an option not to deliver any fluid to the fluid branching device 3870, thereby providing a dry operation mode. It should be noted that pipes 6402, 6404, 6406, 6408, 6422, 6432, 6442, 6452, 6462, and 6472 can be formed of soft rubber or other materials that enable the pipes to be flexible, which can facilitate pipe routing within the outdoor cleaning device of the embodiment. It should also be noted that... Figure 64 The specific number of nozzles, pipes, and outputs of the fluid branching device 3870 shown are for illustrative purposes and not as a limitation, and outdoor cleaning devices constructed according to embodiments of this disclosure may include more than Figure 64The fluid branching device 3870 may include a suitable number of outputs for delivering fluid to each nozzle, and may include fewer nozzles (e.g., at least one nozzle, two nozzles, three nozzles, four nozzles, five nozzles) or more nozzles (e.g., six or more nozzles) as shown in the figure.

[0090] refer to Figure 68 This diagram illustrates an aspect of securing a clamp to an axial locking member of an outdoor cleaning device according to an embodiment of this disclosure. As described above, the axial locking member 4830 may include a cavity 5750, and one or more retaining members 5752 may be disposed within the cavity 5750. The clamp 5800 may be inserted into the cavity 5750 such that the retaining member 5752 is disposed between the inner surfaces of the resilient members 5816 and 5826 (i.e., the retaining member 5752 is located between the resilient members 5826, 5826 and the bases 5810, 5820). A portion of the resilient members 5816, 5826 may be disposed within the cavity of the bases 5810, 5820. The portion of the resilient members 5816, 5826 within the cavity may include a bent end, such as bent ends 6812, 6814. When the bases 5810 and 5820 of the clamp 5800 are separated as described above, the elastic member 5826 can be held between the retaining member 5752 and the inner wall of the cavity 5750. The pressure applied to the elastic members 5816 and 5826 by the bases 5810 and 5820 may cause the elastic members to deform or bend inside the cavities of the bases 5810 and 5820. For example, the bent ends 6812 and 6814 may slide across the cavity of the base 5820, such that the bent end 6812 slides toward the bent end 6814, and vice versa. The sliding of the bent ends 6812 and 6814 (and the bent end of the elastic member 5816) toward each other can cause the bases 5810 and 5820 to separate. On one hand, the recessed portions 6010 and 6020 may form convex surfaces inside the cavities of the bases 5810 and 5820. The convex surface allows the curved ends of the resilient members 5816 and 5826 to slide more easily toward each other. Additionally, it should be noted that these curved ends can come into contact with each other as they slide. If this occurs, the curved ends can then turn toward the retaining member 5752 when the bases 5810 and 5820 separate. When the pressure applied to the release button 3310 is released, the resilient members 5816 and 5826 can return to their normal resting position as the curved ends of the resilient members 5816 and 5826 move away from each other, thereby providing a biasing force that pushes the bases 5810 and 5820 toward each other and causes the clamp 5800 to close. On one hand, the base ( Figure 68(Not shown) can be placed on clamp 5800 and secured to axial locking member 4830 by screws, which can be secured in screw holes 6810 located at end 5742 of axial locking member 4830. It should be noted that... Figure 68 Described as using screws and screw holes 6810 to secure the base to the axial locking member 4830 and to hold the clamp 5800 within the cavity 5750, in some embodiments other mechanisms, such as pins or bars, may be used.

[0091] It should be noted that, as a reference Figures 1 to 68 The various embodiments of outdoor cleaning apparatus described and illustrated according to this disclosure are intended to complement each other and not to limit each other.
