[0042] Embodiments of this disclosure will be described in detail with reference to the accompanying drawings. References to "one embodiment," "implementation," "some embodiments," etc., indicate that the described embodiment may include a particular feature, structure, or characteristic, but not every embodiment may necessarily include that particular feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a particular feature, structure, or characteristic is described in connection with an embodiment, whether explicitly described or not, implementing such a feature, structure, or characteristic in conjunction with other embodiments is considered to be within the knowledge of those skilled in the art.

[0043] Spatial relative terms, such as “below,” “lower,” “lower part,” “above,” “upper,” “upper part,” “opposite,” etc., may be used herein for descriptive purposes to describe the relationship between one element or feature and another element or feature as shown in the figures. Spatial relative terms are intended to cover different orientations of a device in use or operation other than those depicted in the figures. The device may be oriented in other ways (e.g., rotated 90 degrees or otherwise), and the spatial relative descriptors used herein may be interpreted similarly accordingly.

[0044] As used herein, the terms “approximately” or “substantially” indicate a value of a given quantity that may vary based on a particular technique. Based on a particular technique, the terms “approximately” or “substantially” may indicate a value of a given quantity that varies, for example, between 1% and 15% of the value (e.g., ±1%, ±2%, ±5%, ±10%, or ±15% of the value).

[0045] The following examples are illustrative and not limiting of this implementation. Other suitable modifications and adaptations to various conditions and parameters that are commonly encountered in the art and will be obvious to those skilled in the art are all within the spirit and scope of this disclosure.

[0046] Reference Figures 1 to 6 This disclosure includes a spray fan 1 having a fan assembly 100 and a supply box 200. In some embodiments, such as, for example Figures 1 to 2 As shown, the supply tank 200 is directly connected to the fan assembly 100. The supply tank 200 is configured to store fluids, such as water. Directly connecting the supply tank 200 to the fan assembly 100 minimizes the space occupied by the mist fan 1, allowing users to install the mist fan 1 in, for example, a bedroom, office, or workshop without using additional space for the supply tank 200. Therefore, the mist fan 1 provides users with the added benefits and comfort of increased misting without occupying more space than a similarly sized fan lacking misting characteristics.

[0047] In some embodiments, fan assembly 100 has a bounded volume, and spray fan 1 includes a bounded volume. As used herein, a bounded volume is a cuboid enclosing an object. In some embodiments, spray fan 1 includes a ratio of the bounded volume of spray fan 1 to the bounded volume of fan assembly 100 equal to 1. In some embodiments, spray fan 1 includes a supply box 200 coupled to fan assembly 100 such that the supply box protrudes from the bounded volume of fan assembly 100 without interfering with the spatial configuration of a room such as a bedroom, office, or workshop. For example, in some embodiments, the ratio of the bounded volume of spray fan 1 to the bounded volume of fan assembly 100 is less than or equal to 1.5. In other words, coupling supply box 200 to fan assembly 100 does not increase the bounded volume of fan assembly 100 by more than 50%. In some embodiments, the ratio of the bounded volume of spray fan 1 to the bounded volume of fan assembly 100 is less than or equal to 1.4, 1.3, 1.2, or 1.1. In some embodiments, the ratio of the bounded volume of spray fan 1 to the bounded volume of fan assembly 100 is approximately 1. The ratio of the bounded volume of the spray fan 1 to the bounded volume of the fan unit 100, which is close to 1, can improve the user experience by introducing a spray without taking up more space than the fan unit 100 without a spray feature.

[0048] In some embodiments, the fan assembly 100 has a head assembly 105 and a base assembly 110. In some embodiments, the supply box 200 is configured to be coupled to the base assembly 110. As discussed in more detail below, in some embodiments, the head assembly 105 is detachably coupled to the base assembly 110, and the head assembly includes a plurality of legs 1175, such as, for example... Figures 14 to 16As shown, this allows the head assembly 105 to stand independently. In some embodiments, the base assembly 110 includes a base 115, a housing 120, and a support 122 extending from the base 115. In some embodiments, the head assembly 105 is configured to be coupled to the support 122. In some embodiments, the supply box 200 is configured to be coupled to the base 115 and the support 122.

[0049] In some embodiments, the head assembly 105 includes a handle 130, a cylindrical front housing 135, a rear grille 140, and a front grille 145. In some embodiments, the front grille 145 includes a hub 146 disposed on a central portion of the front grille 145. In some embodiments, the head assembly 105 includes a fan 160 disposed within the housing 135.

[0050] In some implementations, such as, for example Figures 2 to 3 As shown, head assembly 105 includes a port 220 configured to receive a first end of hose 210, and supply tank 200 includes a port 215 configured to receive a second end of hose 210. In some embodiments, hose 210 is configured to guide liquid (such as water) from supply tank 200 to head assembly 105. In some embodiments, support 122 includes passages 240 (e.g., channels, pipes, or grooves) to guide and secure hose 210 against support 122.

[0051] In some implementations, such as, for example Figures 4 to 5 As shown, the supply box 200 includes a top surface 201, a bottom surface 202, a rear surface 203, and a sidewall 204 connecting the top surface 201, the bottom surface 202, and the rear surface 203. In some embodiments, the supply box 200 includes a removable cover 270 forming part of the top surface 201. The removable cover 270 allows the user to refill the supply box 200 and also prevents contaminants from entering the supply box 200. In some embodiments, the removable cover 270 is configured to lock onto and unlock relative to the supply box 200. In some embodiments, the removable cover 270 is configured to rotate in and out of a locked position on the supply box 200. In some embodiments, the removable cover 270 is configured to be pressed onto and pulled out of a locked position on the supply box 200. In some embodiments, such as, for example Figures 4 to 5 As shown, the supply box 200 includes a handle 280 configured to pivot upwards (e.g., away from the top surface 201). A user can carry the supply box 200, for example, via the handle 280.

[0052] In some implementations, such as, for example Figure 6As shown, the supply box 200 is configured to be secured to the support 122 and the base 115. For example, in some embodiments, the support 122 and the base 115 include features for securing the supply box 200, such as one or more bosses 245 on the base 115 and / or one or more latches 230 on the support 122.

[0053] For example, in some implementations, such as... Figures 4 to 5 As shown, the rear surface 203 of the supply box 200 forms a receiving portion 225 including a socket 226. In some embodiments, the shape of the receiving portion 225 is configured to receive the support member 122. For example, in some embodiments, the receiving portion 225 is the opposite of the support member 122, or is generally channel-shaped. In some embodiments, the support member 122 is completely disposed within the receiving portion 225. In some embodiments, the support member 122 is at least partially disposed within the receiving portion 225. In some embodiments, the receiving portion 225 forms a flat or convex surface. Although the flat or convex rear surface 203 can exert forces on the supply box 200 away from the support member 122 relative to the channel-shaped rear surface 203 (which may increase the bounded volume of the spray fan 1), it can also facilitate securing the supply box 200 to the fan assembly 100 using a simple supply box 200 design that is easy to manufacture. Ultimately, attaching the rear surface 203 of the supply box 200 to the support 122 reduces the space occupied by the spray fan 1, and the shape of the receiving portion 225 can vary depending on the size of the supply box 200, manufacturing issues, and other considerations.

[0054] In some implementations, such as, for example Figures 7 to 8 As shown, the supply box 200 and the support member 122 include complementary features to secure the supply box 200 to the support member 122. Secure the supply box 200 to the support member 122 reduces the bounded volume of the spray fan 1, such that, for example, the spray fan 1 does not occupy more space than the standalone fan unit 100, despite including the supply box 200. Secure the supply box 200 to the support member 122 also reduces the possibility of the supply box 200 being separated from the fan unit 100. Furthermore, as for example in… Figures 1-2 and Figure 6 As shown, the supply box 200 is fixed to the front of the support 122 to position the center of gravity of the spray fan 1, thereby reducing the possibility that the spray fan 1 may tip forward during use and potentially damage the head assembly 105.

[0055] In some embodiments, the supply box socket 226 is configured to engage a latch 230 on the support member 122. In some embodiments, the latch 230 includes a raised platform 232 on the support member 122. In some embodiments, the raised platform 232 provides a gap between the supply box 200 and the support member 122. The gap introduced by the raised platform 232 can, for example, mitigate vibrations in the supply box 200 that may generate undesirable noise, or can accommodate a tilted rear surface 203 of the supply box 200 that reduces the bounded volume of the spray fan 1 and / or positions the center of gravity of the spray fan 1 to reduce the likelihood of the spray fan 1 tilting forward.

[0056] Furthermore, in some embodiments, the latch 230 includes an internal aperture 231 disposed therein configured to receive a connecting pin 227. In some embodiments, the latch 230 includes a first internal aperture 231 configured to receive a first connecting pin 227 and a second internal aperture 231 configured to receive a second connecting pin 227. In some embodiments, the first and second apertures, and the corresponding first and second connecting pins, are arranged vertically relative to each other, such that, for example... Figures 7 to 8 As shown, the first opening is above the second opening, and the first connecting pin is above the second connecting pin. In other words, in some embodiments, such as... Figure 7 As shown, both the first and second orifices are arranged in the latch 230 along an axis parallel to the longitudinal axis of the support 122. In some embodiments, the first and second orifices, along with their corresponding first and second connecting pins, are arranged horizontally relative to each other. In other words, in some embodiments, both the first and second orifices are arranged in the latch 230 along an axis extending orthogonal to the longitudinal axis of the support 122. Furthermore, in some embodiments, the latch 230 includes more than two internal orifices 231 and more than two corresponding connecting pins 227.

[0057] In some embodiments, the latch 230 includes a tab 233 configured to engage the force-applying member 228 when the socket 226 receives the latch 230. In some embodiments, the tab 233 engages the force-applying member 228 to secure the supply box 200 to the support 122 and prevent separation between the supply box 200 and the support 122. For example, in some embodiments, when a user slides the supply box 200 down onto the latch 230, the socket 226 presses the force-applying member 228 inward, and the tab 233 retains the force-applying member 228 within the socket 226. For example... Figure 8 As shown, when the supply box 200 is fixed to the latch 230, the force-applying member 228 is inside the socket 226.

[0058] In some embodiments, the latch 230 includes a slot 229. In some embodiments, a connecting pin 227 and / or a force-applying member 228 are arranged within the slot 229. In some embodiments, the slot 229 is arcuate, rectangular, circular, oval, elliptical, or any other shape configured to receive a corresponding portion of the latch 230. As discussed, securing the supply box 200 to the support 122 reduces the bounded volume of the spray fan 1 and mitigates the possibility of the supply box 200 separating from the fan assembly 100.

[0059] In some implementations, such as, for example Figures 9A to 11 As shown, the supply box 200 and the base 115 include complementary features, such as protrusions and / or recesses, to secure the supply box 200 to the base 115. For example, in some embodiments, the base 115 includes a boss 245 extending from the base 115. In some embodiments, the boss 245 extends from a base platform 116 that protrudes relative to the base 115. The base platform 116 provides increased thickness at the central portion of the base 115 (e.g., where the supply box 200 rests) to improve durability and stability. In some embodiments, such as in… Figures 9A to 9B As shown, the spray fan 1 includes a clamp 235, which is coupled to the support 122 and configured to hold the hose 210 in place. For example... Figure 9A As shown, clamp 235 may include a fork configured to secure hose 210. In some embodiments, such as... Figure 9B As shown, clamp 235 includes a plurality of channels configured to secure hose 210 at a plurality of points along hose 210. Figures 9A to 9B A non-limiting example of clamp 235 is shown. Clamp 235 can be any structure configured to secure hose 210.

[0060] For example Figure 11 As shown, in some embodiments, the supply box 200 includes a bottom port 250 disposed in a bottom surface 202. In some embodiments, the bottom port 250 is configured to receive a boss 245. In some embodiments, the bottom port 250 is configured to receive a boss 245 such that the bottom surface 202 coincides with the base platform 116. The connection between the boss 245 and the bottom port 250 secures the supply box 200 to the base 115 and mitigates the swaying and separation of the supply box 200 from the fan assembly 100. In some embodiments, the boss 245 is oval, rectangular, circular, triangular, or any other shape suitable for engaging the corresponding opposite shape forming the bottom port 250. Furthermore, in some embodiments, the boss 245 has a uniform thickness. In some embodiments, the boss 245 has a variable thickness. In some embodiments, the boss 245 has a tapered edge.

[0061] In some implementations, such as, for example Figure 6 As shown, the supply box 200 is configured to be secured to the fan assembly 100 at the support 122 and the base 115. In some embodiments, the supply box 200 is configured to be secured to the fan assembly 100 only at the support 122. In some embodiments, the supply box 200 is configured to be secured to the fan assembly 100 only at the base 115. In some embodiments, the supply box 200 and the fan assembly 100 have additional complementary features to secure the supply box 200 to the fan assembly 100, such as a second boss extending from the platform 116 and a corresponding second bottom port, and / or a second latch and a corresponding second socket. In some embodiments, the spray fan 1 includes fasteners, such as straps or cables, configured to secure the supply box 200 to the fan assembly 100. Finally, the supply box 200 can be secured to the fan assembly 100 in any manner suitable for reducing the possibility of separation of the supply box 200 from the fan assembly 100 and / or reducing vibration during operation.

[0062] In some implementations, such as, for example Figure 12 As shown, the spray fan 1 includes a nozzle 205 disposed on a head assembly 105. In some embodiments, the longitudinal axis 206 of the nozzle 205 forms an angle 260 with the front surface 255 of the head assembly 105. In some embodiments, the longitudinal axis 206 of the nozzle 205 forms an angle 260 of at least 15 degrees outward from the head assembly 105. Orienting the nozzle 205 at an angle 260 to the head assembly 105 promotes the spray away from the head assembly 105 and travels in the direction of airflow, opposite to travel into the head assembly 105. In some embodiments, the angle 260 between the longitudinal axis 206 of the nozzle 205 and the front surface 255 of the head assembly 105 is between 15 degrees and 90 degrees. In some embodiments, the angle 260 is between 15 degrees and 30 degrees, between 30 degrees and 45 degrees, between 45 degrees and 60 degrees, between 60 degrees and 75 degrees, or between 75 degrees and 90 degrees. In some embodiments, the spray fan 1 includes a first nozzle and a second nozzle disposed on the opposite side of the head assembly and / or near the front housing 135.

[0063] Positioning the nozzle 205 on the opposite side of the head assembly 105 and / or near the front housing provides easier access to the internal piping carrying fluid via the hose 210 (e.g., from the supply box 200) to the nozzle 205, allowing personnel, for example, assembling the spray fan 1, to route the internal piping to the nozzle 205 in an area of ​​the spray fan 1 with sufficient space for hands and / or tools. In some embodiments, such as... Figure 12As shown, the spray fan 1 includes a first nozzle and a second nozzle arranged on opposite sides of the head assembly 105. In some embodiments, the first nozzle and the second nozzle are arranged on opposite sides of the hub 146. In some embodiments, such as... Figure 1 As shown, when viewed in a front view, the first nozzle of the spray fan 1 is positioned on the left side of the hub 146, and the second nozzle is positioned on the right side of the hub 146. In some embodiments, when viewed in a front view, the first nozzle is positioned above the hub 146, and the second nozzle is positioned below the hub 146. In some embodiments, the first nozzle is positioned above and to the left of the hub 146, and the second nozzle is positioned below and to the right of the hub 146. In some embodiments, the first nozzle is positioned below and to the left of the hub 146, and the second nozzle is positioned above and to the right of the hub 146. Furthermore, in some embodiments, the spray fan 1 includes more than two nozzles.

[0064] In some implementations, such as, for example Figure 12 As shown, the nozzle 205 is disposed in a recess 137 of the housing 135. In some embodiments, the housing 135 includes a bend 136 near the recess 137 that extends the housing 135 in front of the nozzle 205 in a local area near the nozzle 205. If, for example, the spray fan 1 tilts forward, the bend 136 protects the nozzle 205.

[0065] Furthermore, in some implementations, such as for example Figure 13 As shown, pump 265 is disposed within head assembly 105. Pump 265 is configured to draw liquid from supply tank 200 (e.g., via hose 210 and internal piping) into nozzle 205 to atomize the liquid and produce a spray. For example, pump 265 can be any pump or suction device configured to generate a sufficiently strong vacuum to draw liquid from supply tank 200 into nozzle 205.

[0066] Furthermore, in some embodiments, the spray fan 1 includes a plurality of nozzles arranged on the hub 146. For example, in some embodiments, such as Figure 14 As shown, the spray fan 1000 includes a spray unit 1150 comprising a plurality of nozzles 1205 disposed on a hub 1146. In some embodiments, the spray unit 1150 includes a single nozzle 1205. In some embodiments, the spray unit 1150 can be detached from the head assembly 1105.

[0067] Furthermore, as previously mentioned, in some embodiments, the head assembly 105 is configured to be detachably coupled to the base assembly 110. For example, in some embodiments, such as Figures 14 to 18As shown, the spray fan 1000 includes a head assembly 1105, which can be disengaged from the base assembly 1110 and can operate as a separate unit detached from the base assembly 1110. In some embodiments, the supply box 200 is configured to be connected to the head assembly 1105 via a hose 210 connected to the spray fan port 1220. In some embodiments, the supply box 200 can be placed on, for example, a table or a floor. In some embodiments, the supply box 200 is configured to be placed on a surface lower or higher than the support leg 1175.

[0068] Head assembly 1105 may have features substantially similar to head assembly 105, including nozzle 205 (e.g., as shown in example). Figures 1 to 12 The arrangement shown is near the outer periphery of the head assembly 105 and / or, for example, Figure 14 The nozzle 205 and pump 265 are arranged on the hub 146 as shown. Therefore, Figures 14 to 22 References are made to components that are substantially similar to those previously disclosed, and include, relative to... Figures 1 to 13 Add part number reference 1000. Unless otherwise specified (e.g., explicitly referencing...). Figures 1 to 13 The following paragraphs relate to... Figures 1 to 13 Add part number 1000, but similar parts can be found in [reference needed]. Figures 1 to 13 The part number reference is for readability.

[0069] In some embodiments, the head assembly 1105 includes three, four, five, six, or seven legs 1175. In some embodiments, at least one leg 1175 (such as leg 1175A) includes an attachment mechanism 1176 disposed on an outer surface 1186 of the leg 1175. In some embodiments, the attachment mechanism 1176 includes a protrusion or button configured to be received within an opening 1124 of a housing 1120, the housing 1120 being configured to cover the leg 1175 when the head assembly 1105 is attached to the base assembly 1110, such as... Figure 22 As shown. In some embodiments, the attachment mechanism 1176 is coupled to the actuation mechanism 1179, which is configured such that the attachment mechanism 1176 is movably disposed through an opening, for example, in the leg 1175A. In some embodiments, the attachment mechanism 1176 is arranged on the side of the housing 120. In some embodiments, such as, for example... Figure 22 As shown, the attachment mechanism 1176 is arranged on the rear of the housing 1120.

[0070] In some embodiments, the folded position when the head assembly 1105 is attached to the base assembly 1110 or when the head assembly 1105 is initially detached from the base assembly 1110 (e.g.) Figure 18During translation (as shown), the joint motion mechanism 1300 causes the outriggers 1175 to translate together in unison to their extended positions as when the head assembly 1105 has been disengaged from the base assembly 1110 and the outriggers 1175 have been opened from their folded positions (as shown). Figures 14 to 16 (As shown). In some embodiments, the joint motion mechanism 1300 includes a plurality of interconnected gears 1305, such as... Figure 17 As shown. Gear 1305 enables the outriggers 1175 to perform synchronized joint movements, such that, for example, outrigger 1175A translates between a folded position and an extended position (or vice versa), while the other outriggers 1175 perform joint movements in unison with the translated outrigger 1175A. In this way, it is easier to extend the outriggers 1175 between the folded and extended positions compared to embodiments that require individual outrigger joint movements.

[0071] In some embodiments, the gear 1305 of the articulation mechanism 1300 is arranged at the first end of each support leg 1175. In some embodiments, the first end 1183 of each support leg is adjacent to the power housing 1177 and opposite to the second end 1184, as shown below. Figure 16 As shown. In some embodiments, the first end 1183 of each leg 1175 may include a neck 1181, which may be integrally formed with the cylindrical transverse member 1182. In some embodiments, a gear 1305 is arranged at each end of the transverse member 1182. For example, as Figure 17 As shown, in some embodiments, outrigger 1175A includes gears 1305A-1 and 1305A-2 at the end of the transverse member 1182A. In some embodiments, a second adjacent outrigger 1175B includes gears 1305B-1 and 1305B-2 disposed at the end of its respective transverse member 1182B. Gear 1305A-2 of outrigger 1175A can engage with gear 1305B-1 of outrigger 1175B. Similarly, gear 1305B-2 of outrigger 1175B can engage with gear 1305C-1 of outrigger 1175C. In some embodiments, neck 1181, transverse member 1182, and gears 1305 are disposed within frame 1310, as... Figure 17 As shown. In some embodiments, the frame 1310 accommodates the first end 1183 of the leg 1175 so that the gears 1305 of adjacent legs 1175 can be folded or extended in a consistent manner.

[0072] Returning to base component 1110, as follows Figure 18 As shown, in some embodiments, the receiving portion 1400 may be coupled to the support 1122 to facilitate coupling with the head assembly 1105. Figure 18 For clarity, the text has been removed. Figure 22The housing 1120 is shown. In some embodiments, the receiving portion 1400 is an elongated member having a plurality of attachment features configured to engage and secure the head assembly 1105. In some embodiments, when the legs 1175 are configured as follows... Figure 18 In the folded position shown, a cavity is formed in the leg 1175 along its length. In some embodiments, the head assembly 1105 is configured to attach to the receiving portion 1400 such that the leg 1175 can be positioned on top of the receiving portion 1400 and can slide downward onto the receiving portion 1400. In some embodiments, attachment features on the leg 1175 (such as, for example...) Figure 16 and Figure 20 The protrusion 1180 shown engages with the attachment feature on the receiving portion 1400 to allow the head assembly 1105 to be attached to the base assembly 1110.

[0073] The exemplary attachment features of the receiving section 1400 can be Figures 19A to 19B and Figure 20 As seen in the image. In some embodiments, the receiving portion 1400 includes an elongated shape extending between a first end 1420 and a second end 1425. In some embodiments, a pair of opposing surfaces 1405 extend from the first end 1420 of the receiving portion 1400 toward the second end 1425. In some embodiments, the opposing surfaces 1405 have a substantially helical shape extending around the receiving portion 1400. In some embodiments, the opposing surfaces 1405 extend from a first side of the receiving portion 1400, such as... Figure 19B Orientation shown Figure 19A The receiving portion 1400 shown has a notch 1410 on its second side. In some embodiments, a guide path F is defined therebetween by an opposing surface 1405.

[0074] In some embodiments, the protrusion 1180 is arranged on, for example, the inner surface 1185 of the leg 1175A, such as... Figure 16As shown, and received between opposing surfaces 1405, the protrusion 1180 can be translated along the guide path F into the recess 1410 when the head assembly 1105 is coupled to the receiving portion 1400. In some embodiments, the opposing surfaces 1405 extend from a vertex 1430 adjacent to a first end 1420 of the receiving portion 1400. In some embodiments, the vertex 1430 causes the protrusion 1180 to translate along surface 1405A in a first rotational direction or along surface 1405B in a second rotational direction. In this way, regardless of the orientation of the head assembly 1105 when initially coupled to the base assembly 1110, the protrusion 1180 on at least one of the legs 1175 can engage with either of the opposing surfaces 1405 and can be guided downward along the guide path F to a fixed position within the recess 1410 without requiring the user to manually secure the head assembly 1105 to the base assembly 1110. The head assembly 1105 coupled to the base assembly 1110... Figure 20 In the cross-sectional view shown, for example, the protrusion 1180 of the outrigger 1175A can be observed within the recess 1410 after traveling along either of the opposing surfaces 1405A and 1405B.

[0075] In some embodiments, the head assembly support 1172 connects the rear housing 1165 to an oscillation unit 1174 configured to rotate the head assembly 1105. In some embodiments, the head assembly support 1172 connects the rear housing 1165 to the oscillation unit 1174, which is configured to rotate the head assembly 1105 relative to a plurality of legs 1175.

In some embodiments, the user interface 1162 includes multiple user input mechanisms, such as buttons, sliders, and / or touch displays, configured to receive user input and control operations. In some embodiments, control operations include power and oscillation settings, scheduling, fan speed, and / or spray intensity. In some embodiments, the spray fan 1000 includes a remote control unit 1170. In some embodiments, the remote control unit 1170 is detachable from a rear housing 1165 protruding, for example, from a rear grille 1140. In some embodiments, the remote control unit 1170 includes multiple user input mechanisms, such as buttons, sliders, and / or touch displays, configured to receive user input and control operations. In some embodiments, control operations include power and oscillation settings, scheduling, fan speed, and / or spray intensity.

[0077] Furthermore, in some embodiments, the support 1122 includes a power supply 1125. In some embodiments, the power supply 1125 may be a DC power supply and may include an electrical connector or jack. The DC power supply may be provided via a charging device configured to receive AC power at a first side and generate DC power at a second side (e.g., at the electrical connector of the power supply 1125). The charging device may include an electromagnetic compatibility (EMC) housing comprising a printed circuit board. The printed circuit board may include an AC / DC converter configured to generate DC power based on the received AC power. For example, when the head assembly 1105 is coupled to the base assembly 1110, the head assembly 1105 may receive power via the power supply 1125 disposed in the support 1122 of the base assembly 1110.

[0078] In some embodiments, the power housing 1177 and the power supply 1178 are disposed below the articulation mechanism 1300. In some embodiments, the power supply 1178 is a DC power supply and includes an electrical connector or jack. The DC power supply may be provided via a charging device configured to receive AC power at a first side and generate DC power at a second side (e.g., at the electrical connector of the power supply 1178). The charging device may include an electromagnetic compatibility (EMC) housing including a printed circuit board 1154B. In some embodiments, the printed circuit board 1154B includes an AC / DC converter configured to generate DC power based on the received AC power. In some embodiments, when the head assembly 1105 is decoupled from the base assembly 1110, the head assembly 1105 receives power via the power supply 1178 disposed in the power housing 1177.

[0079] In some embodiments, the head assembly 1105 is electrically connected to the base assembly 1110 via corresponding electrical connectors disposed in the head assembly 1105 and the base assembly 1110. For example... Figure 20 and Figures 21A-21B As shown, in some embodiments, the head assembly 1105 includes a first electrical connector 1187 disposed within a power housing 1177. In some embodiments, the first electrical connector 1187 is a male connector receivable within a second electrical connector 1435 disposed at a first end 1420 of a receiving portion 1400. In some embodiments, the second electrical connector 1435 is a female connector. In some embodiments, the first electrical connector 1187 is a female connector, and the second electrical connector 1435 is a male connector. In some embodiments, the first electrical connector 1187 can be received within the second electrical connector 1435 when the power housing 1415 of the receiving portion 1400 engages with the power housing 1177 of the head assembly 1105. In this way, when the head assembly 1105 is received on and connected to the receiving portion 1400 of the base assembly 1110, the head assembly 1105 can receive power via a power supply 1125 disposed in a support member 1122 of the base assembly 1110. In some implementations, wiring W connects the second electrical connector 1435 to the power supply 1125.

[0080] In some embodiments, when the head assembly 1105 is disconnected from the base assembly 1110, the head assembly 1105 receives power via the first electrical connector 1187. In some embodiments, such as... Figure 23 As shown, power supply 1178 is connected to first electrical connector 1187 to provide power to components of head assembly 1105. For example, in some embodiments, wiring W receives power from first electrical connector 1187 and provides power to oscillating motor 1152, fan motor 1151, rechargeable battery 1153, and other electrical components such as printed circuit board 1154. In some embodiments, printed circuit board 1154A is configured to control the operation of fan motor 1151 or oscillating motor 1152, and the charging operation of rechargeable battery 1153. In some embodiments, printed circuit board 1154B may be communicatively connected to user interface 1162 and printed circuit board 1154A to transmit user input received via user interface 1162 to printed circuit board 1154A. The arrangement of rechargeable battery 1153 allows head assembly 1105 to operate independently of the base assembly 1110 and not connected to power supply 1178. Alternatively, power supply 1178 can be connected in a separate configuration to first electrical connector 1187 to charge battery 1153 and provide power to head assembly 1105.
