[0002] Embodiments of the present invention relate to a makeup device that automatically moves a spray device in multiple directions to apply a skin spray to a user.

Background Art

[0003] The global cosmetics market is a multi - billion - dollar industry, and the demand for beauty and skin - care products continues to increase. However, the increase in overall spending on cosmetics does not necessarily lead to an improvement in the makeup techniques of the general consumer. Many people do not have the time, money, or patience to repeatedly practice makeup. When applying makeup manually, results that are far from expectations and sometimes inconsistent may occur. For those who are not used to it, the experience of applying makeup may be frustrating. Not everyone has the time and resources to seek help from an expert every time makeup is needed.

[0004] Advances in robotics, artificial intelligence, and control technology present potential opportunities for the automation of cosmetics application. For example, it has been shown that robots can be trained to use an eyeshadow brush on a person's face. For a makeup device to be practical for the user, such a machine needs to have, among other things, versatility, compactness, ease of use, and safety. However, compactness and versatility are sometimes two conflicting goals. A machine with diverse functions may tend to be large. On the other hand, a compact machine usually does not have enough space to arrange all the mechanical components necessary to implement all the desired functions.

[0005] In compact machines such as handheld sprays, the user has to manually move the cosmetics, so the cosmetics cannot be applied accurately. Using a stationary machine may improve accuracy. However, in order to apply cosmetics to different areas of the user's face, the user may sometimes be required to physically change the position of their head several times (for example, facing forward, turning to the right, turning to the left, etc.), so that the machine can reach the left and right positions of the user's face. Changing the position may shift the position of different sides of the user's face by the machine, resulting in undesirable results. Designing and constructing a makeup machine that is versatile, compact, and equipped with movable parts suitable for widely applying cosmetics to the user's face is a challenge.

Summary of the Invention

[0006] In one embodiment, the apparatus includes a spray head having a container for receiving a spray cartridge including a skin spray, a main body housing a control circuit for controlling the position of the spray head relative to the object of the skin spray, an arch-shaped track having a curved shape on a horizontal plane, and a vertical support attached to the arch-shaped track. The control circuit slides the spray head along the arch-shaped track and adjusts the height of the vertical support to move the arch-shaped track and the spray head up and down.

[0007] In another embodiment, the apparatus includes a spray head, a main body, an arch-shaped track, at least one vertical support, and a linear track. The spray head has a container for receiving a spray cartridge including a skin spray. The main body houses a control circuit for controlling the position of the spray head relative to the object of the skin spray. At least a part of the main body is positioned between the arch-shaped track and the object. The arch-shaped track has a curved shape on a horizontal plane. The control circuit slides the spray head along the arch-shaped track. At least one vertical support has an adjustable height and is attached to both the right and left sides of the arch-shaped track. The linear track is controlled by the control circuit to adjust the horizontal distance between the spray head and the object.

DETAILED DESCRIPTION OF THE INVENTION

[0011] In the following description, numerous specific details are set forth. However, it is understood that embodiments of the present invention may be practiced without these specific details. In other instances, well-known circuits, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification. However, those skilled in the art will understand that the present invention can be practiced without such specific details. Those skilled in the art will be able to implement appropriate functions without undue experimentation upon reading the included description.

[0012] This specification discloses a makeup machine (also referred to as a "machine" or "device") that can automatically apply specially designed makeup to a user's face. Although the term "makeup" is used in this specification, it should be understood that the disclosed machine can apply any skin spray product, such as cosmetics, skin care products, pharmaceuticals, etc., to a user's skin. Therefore, "makeup" is understood to be a non-limiting example of the use of the disclosed machine that sprays the contents of a spray cartridge onto a user's skin. Although the following description mainly focuses on the user's face, the devices and methods of the present invention can be applied to any part of the human body.

[0013] The makeup machine applies a skin spray to a target area such as a user's face. A skin spray, also called a product for spraying on the skin, includes cosmetics, skin care products, skin pharmaceuticals, dermatological products, and the like. In some embodiments, the skin spray may be a liquid material that includes a liquid, fluid, or solution, a fluid mixture, an oil, a lotion, or any material of any viscosity that can be sprayed with compressed air. For the sake of simplicity in the following description, the term "liquid" may refer to a skin spray.

[0014] The makeup machine includes an arch-shaped structure that provides an arch-shaped track at the top. The arch-shaped track has an arch shape on a horizontal plane. The spray head is mounted on the arch-shaped track and can slide horizontally from one end of the arch-shaped track to the other end. The arch-shaped track is symmetric about a horizontal center line passing through the center of the arch-shaped track, that is, the left and right sides of the arch-shaped track are symmetric. The object (e.g., the user's head) can be positioned on this horizontal center line so that the spray emitted from the spray head can reach both sides of the user's face. In one embodiment, the machine includes a jaw support for the user to place their head on. The jaw support may be positioned on this horizontal center line and attached to the front of the main body of the machine. In an embodiment where the shape of the arch-shaped track is a part of a circle, the jaw support may be positioned offset from the center. For example, the geometric center of the jaw support on the horizontal plane does not coincide with the center of the circle. The jaw support in such an embodiment may be positioned on the center line in the direction away from the center of the arch-shaped track (i.e., the direction towards the user). This offset positioning provides space for the movement of the spray head and ensures that the protruding part (such as the nose) of the user does not interfere with the movement of the spray head.

[0015] In addition to the left and right lateral movement, the spray head can move back and forth on a horizontal plane. The spray head can slide backward on a linear track to increase the horizontal distance to the object or slide forward on a linear track to reduce this distance. Two embodiments of the linear track will be described with reference to FIGS. 1 and 10. If the types of skin sprays are different, the required distance between the spray head and the user may also be different. For example, to highlight the facial contour, it is necessary to bring the spray head closer to the user's face, and to apply foundation, it is necessary to move the spray head away from the face. The combination of the arch-shaped track and the linear track enables the spray head to easily maintain an appropriate distance from the user's face.

[0016] The makeup device further includes a height adjustment mechanism for adjusting the height of the spray head relative to the user's face. In one embodiment, the height adjustment mechanism includes an arcuate track and one or more vertical columns attached to the arcuate track for vertically moving the spray head thereon. For example, the arcuate track may be supported by columns that can vertically expand and contract to move the arcuate track up and down. The columns enable the spray head to reach the entire vertical range of the user's face, from the top of the forehead (when the columns are fully extended) to the chin (when the columns are fully retracted). In another embodiment, the height adjustment mechanism may include a vertical support column attached to the spray head for moving the spray head up and down. By moving the arcuate track and the spray head thereon together, the stability of the spray head and the accuracy of the spray during the operation of the machine are improved.

[0017] A spray cartridge containing one or more types of skin spray can be inserted or placed in the spray head and removed after use. The spray cartridge has one or more nozzles around it and can be horizontally rotated about its central axis to direct the nozzles towards the object. As will be described in more detail below, the rotation of the spray cartridge can increase the angle range of the spray, in particular.

[0018] The makeup machine can be placed on a tabletop or countertop with a minimum installation area. The compact size of the machine benefits from the combination of an arched track, a linear track, a telescopic support column, and a rotatable spray cartridge. The linear track allows the horizontal distance between the spray head and the user's face to be adjusted, so the side of the arched track can be brought closer to the side of the face, that is, the radius of the arched track can be minimized. The rotation of the spray cartridge can further shorten the length of the arched track, which is directly proportional to the curvature of the arch with a fixed radius. To widen the spray angle range, the spray cartridge can rotate horizontally by a predetermined angle range around its central axis. Therefore, the curvature of the arched track can be reduced to less than 180 degrees, and the spray can still reach from ear to ear on both sides of the user's face. Furthermore, the column that enables the vertical movement of the spray head can retract into the machine, for example, into the side structure of the machine. The retracted part of the column is not visible to the user and does not take up space. Therefore, the height of the machine can be minimized. Since the mechanical structure where the spray head moves is very compact, the installation area on the tabletop is similar to that of a laptop computer.

[0019] In one embodiment, the main body of the makeup machine houses a control circuit and a motor that drives the movement of the spray head. At least a part of the main body is positioned in front of the arched track and between the arched track and the user. As used herein, the term "front" refers to the side facing the user, and the term "rear" refers to the side away from the user. The compact size of the machine further benefits from the position of the main body.

[0020] As described in the following embodiments, the makeup machine is compact, versatile, easy to use, and safe. The spray head is flexible in movement, completely covers the user's face, and the spray operation is accurate. Throughout the makeup process, a sufficient distance and appropriate angle can be maintained between the spray head and the user's face. The user can remain stationary in the same position during the operation of the machine, and the spray head moves along an arched trajectory around the user's face. Therefore, the skin spray can be sprayed onto the entire face with high precision without the user having to rotate or change the position of the head, and without causing the aforementioned alignment problems caused by changing the position of the head.

[0021] In the drawings accompanying the following detailed description, a circular disk is shown as an example of a spray cartridge. It is understood that the disclosed makeup machine is not limited to a circular shape and other shaped spray cartridges can be used. Further, the spray head may have a different shape to accommodate a spray cartridge of a different size and / or shape than that shown in the drawings. The spray cartridges disclosed herein can be used in other machines that can spray atomized liquid onto the skin of the user, and the makeup machines disclosed herein can use other types of spray cartridges and are not limited to the spray cartridges illustrated and described in this disclosure.

[0022] FIG. 1 shows a makeup device 100 according to an embodiment. The makeup device 100 includes a main body 110 having two side arms 120. There is an arch-shaped track 130 on the upper part of the main body 110 and the side arms 120. The arch-shaped track 130 has an arch shape that is part of a circular, elliptical, curved shape, or a combination of multiple curved shapes. The spray head 150 is mounted on the upper part of the arch-shaped track 130. More specifically, the spray head 150 is installed on an orbital connector 140 that connects the spray head 150 to the arch-shaped track 130. The upper part of the orbital connector 140 is a linear track 145, and the spray head 150 can slide back and forth along the linear track 145 to adjust the horizontal distance between the spray head 150 and the user's face. The orbital connector 140 may house one or more motors that move the spray head 150 across the arch-shaped track 130 and / or rotate the spray cartridge 250 within the spray head 150 and / or move the spray head 150 along the linear track 145.

[0023] In one embodiment, the spray head 150 has a front opening (e.g., the front opening 251 in FIG. 2) through which the spray cartridge 250 is visible. The spray cartridge 250 may include a plurality of nozzles 152 around it. Further details regarding the spray cartridge 250 are provided below with reference to FIG. 2.

[0024] On the front side of the main body 110, there is a jaw support assembly 160 having an elongated shape in the vertical direction. The upper part of the jaw support assembly 160 is placed on the upper part of the front of the main body 110. On the upper surface of the jaw support assembly 160, there is a support pad 165 on which the user's jaw is placed. The jaw support assembly 160 helps support the user's jaw and position the user's head in an optimal use position (e.g., with respect to depth and height) and posture (to achieve optimal spraying ability on the skin to avoid wrinkles). In this embodiment, the jaw support assembly 160 includes a vertical stand that extends longitudinally along the front side of the main body 110 and reaches the surface (e.g., a tabletop) on which the machine 100 stands.

[0025] Machine 100 may also include an observation surface 170 such as a mirror or a digital display screen. The observation surface 170 is supported by a folding stand 175 that can be folded at the top of the machine 100. The folding stand 175 is fixed to the rear side of the main body 110. The observation surface 170 faces the user's face when the folding stand 175 is in the deployed position. The observation surface 170 faces the top of the main body 110 when the folding stand 175 is in the stored position. In one embodiment, the observation surface 170 and the folding stand 175 can be packaged and sold as separate modules from the rest of the machine 100. Further details about the observation surface 170 will be provided after the description of FIG. 17.

[0026] The side arm 120 curves towards the user who receives the skin spray. The rear wall of the side arm 120 and the rear wall of the main body 110 form the curved outer wall of the machine 100. The side arm 120 may include electronic circuits embedded therein, such as speakers, wireless interfaces (e.g., Bluetooth, Wi-Fi). The (inner) wall of each side arm 120 facing the user may include a speaker grill 122 that protects the speaker components inside the side arm 120.

[0027] Figure 2 is an exploded view of the makeup machine 100 of FIG. 1 according to one embodiment. To avoid cluttering the drawing, some of the components shown in FIG. 1 are omitted in FIG. 2. FIG. 2 shows that the machine 100 includes two columns 210 that extend upward from their respective side arms 120 and support both the right and left sides of the arched track 130. The two columns 210 can be telescoped tandemly to move the arched track 130 up and down. Although two columns 210 are shown in FIG. 2, in alternative embodiments, the machine 100 may include any number of columns for supporting the arched track 130. The main body 110 has an upper cover 230 that can open to expose an internal cavity where a rack 220 can be disposed. The rack 220 includes a circuit board (which may include one or more processors integrated thereon) for controlling the movement of the spray head, an air tank for storing compressed air, and a motor for operating the machine 100. In one embodiment, the rack 220 may be pre-assembled and disposed within the main body 110. The rack 220 may include corner latches that are fastened to the main body 110.

[0028] The columns 210 are housed within the side arms 120. When the arched track 130 is lowered and placed on top of the main body 110, the columns 210 are hidden inside the side arms 120. The side arms 120 provide stability to the main body 110 when the track connector 140 (and the spray head 150 thereon) is at the outermost end on the left or right side of the arched track 130. A number of speakers 270 and subwoofers 275 may be attached within the side arms 120 and / or to the front side of the main body 110.

[0029] In one embodiment, the upper cover 230 of the main body has a rear portion that is lower in height than the front portion. The rear portion is where the arched track 130 is in the storage position. The front portion of the upper cover 230 has a notch that engages with the jaw support assembly 160 so that the jaw support assembly 160 is firmly attached to the main body 110.

[0030] In one embodiment, the jaw support assembly 160 includes one or more sensors 262 under the support pad 165 to detect movement of the user's head. Pressure sensors are installed under the support pad 165 to detect whether the user's jaw is on the support pad 165, and as a safety feature, may generate a warning signal or stop the operation of the machine if the user suddenly leaves. In one embodiment, the jaw support assembly 160 may integrate a rear-facing camera that captures the position of the spray head and / or the color code of the cartridge through the front opening 251 or front window of the spray head 150. The rear side (near the upper end) of the jaw support assembly 160 may include one or more proximity sensors to confirm that nothing is falling into the movement zone of the spray head to enhance safety.

[0031] This support pad 165 is ergonomically shaped to support the user's jaw and minimize movement of the user's head. In one embodiment, the support pad 165 may be removed from the machine 100 and washed or cleaned. The user may purchase a new-shaped or -colored support pad 165 as an accessory and can easily position the support pad 165 in place using magnets or other attachment means. The user may also remove the front cover of the jaw support assembly 160 and replace it with one having a different design pattern. In one embodiment, the jaw support assembly 160 may be removed from the machine 100 and washed or cleaned.

[0032] FIG. 2 shows a spray cartridge 250 loaded into a container 240 of the spray head 150. The container 240 may be closed by an upper lid 255 of the spray head 150. The user may open the upper lid 255 and place the spray cartridge 250 into the container 240. In one embodiment, the bottom area of the container 240 may be slightly smaller than the spray cartridge 250 such that the bottom surface of the spray cartridge near the front side is exposed. To remove the spray cartridge 250 from the spray head 150, the user may open the upper lid 255 and grasp both the top and bottom of the spray cartridge 250 at the front end and lift the spray cartridge 250.

[0033] The spray cartridge 250 may include one or more nozzles 152 positioned around it. Through a front opening 251, one of the nozzles 152 can spray a skin spray onto the user's face. Further, the front opening 251 provides a passage to the skin spray when the spray cartridge 250 rotates within a limited range to reach a wider target area. In some scenarios, rotation within a limited range can be used to create a diffusion effect.

[0034] In one embodiment, the spray cartridge 250 includes a plurality of compartments, each compartment including a liquid tank for storing a liquid and a nozzle for spraying the liquid stored within the corresponding liquid tank. Different skin spray materials may be stored in different liquid tanks. Some nozzles may have different shapes and / or sizes. In another embodiment, the spray cartridge 250 may include a single liquid tank and a single nozzle containing a single liquid material. In such an embodiment, the spray cartridge 250 may sometimes be referred to as a pod. During operation of the machine 100, a motor drives the spray head 150 to rotate the spray cartridge 250 such that a selected nozzle can point at the user's target area.

[0035] Although not shown in FIGS. 1 and 2, in some embodiments, the machine 100 may include an under-desk unit that houses components that generate vibration or noise, or otherwise cause distraction or undesirable effects. It is understood that the under-desk unit may be placed on the floor under the desk on which the main body 110 is placed or on a low shelf. This unit can be connected to the components on the desk via electrical cables, air pipes, etc. Examples of components within the unit may include, but are not limited to, a power supply, a cooling system, an air pump (for generating compressed air), etc. In one embodiment, the subwoofer 275 may be positioned within this unit instead of the main body 110 to obtain an optimal bass acoustic effect.

[0036] In the following description with reference to FIGS. 3 to 9, the observation surface 170 is omitted for simplicity of illustration.

[0037] Figures 3 and 4 show the vertical movement of the arch-shaped track 130 and the spray head 150 according to one embodiment. The column 210 functions as a height adjustment mechanism that expands and contracts to adjust the height of the arch-shaped track 130 and the spray head 150 on the arch-shaped track 130. Although two columns are shown, it is understood that the machine 100 may include other forms of vertical supports to adjust the height of the arch-shaped track 130 and the spray head 150 thereon. In one embodiment, the vertical support is attached to the bottom of both the right and left sides of the arch-shaped track 130 to provide stability when the spray head 150 moves to either end of the arch-shaped track 130. As used herein, the terms "right side" and "left side" refer to any point on the arch-shaped track 130 to the right and left of the midpoint of the arch-shaped track 130, respectively. Examples of vertical supports may include, but are not limited to, one or more columns 210, one or more telescopic struts, a vertical wall extending from the right side to the left side of the arch-shaped track 130, a stand, or a panel. It is understood that the vertical support of the arch-shaped track 130 can be telescopic as shown in the examples of Figures 3 and 4, regardless of its shape. In one embodiment, the vertical support can be hidden inside the machine 100 or the structure attached to the machine 100 when contracted, regardless of its shape. In Figure 3, the arch-shaped track 130 is in the storage position. In Figure 4, the column 210 extends upward to move the arch-shaped track 130 and the spray head 150 to a higher position. In one embodiment, the two columns 210 are driven by a motor to expand and contract tandemly, causing the arch-shaped track 130 to move up and down. In one embodiment, the two columns may be integrally connected by a belt or a rod at or near their lower ends to ensure their tandem movement. In one embodiment, each column 210 may be driven by a screw-type linear motor to cause vertical movement.

[0038] FIG. 5 is a top view showing the radial movement of the spray head 150 on the linear track 145 according to one embodiment. The radial movement of the spray head 150 on the linear track 145 is indicated by the dashed outline of the spray head 150. This movement adjusts the horizontal distance between the spray head 150 and the user's face. The spray head 150 can slide back and forth relative to the user's head along the linear track 145, and the linear track 145 can move with the spray head 150 from one end to the other end of the arch-shaped track 130. The spray head 150 can slide along the linear track 145 when the linear track is at any given position on the arch-shaped track 130. Since the longitudinal direction of the linear track 145 is perpendicular to the tangent of the arch-shaped track 130, it defines the direction of the radial movement of the spray head 150.

[0039] FIG. 5 also shows that the spray head 150 can rotate the spray cartridge 250 clockwise and counterclockwise inside to adjust the aiming of the spray at the user's face. The rotational movement during the spraying operation can increase the angular range of the spray. The spray from the spray cartridge 250 can pass through the front opening 251 (FIG. 2) on the front side of the spray head 150. In an embodiment where the spray cartridge 250 has a plurality of nozzles around it, the spray head 150 may rotate the spray cartridge 250 to select different nozzles for spraying.

[0040] Figures 6A and 6B are top views showing the lateral movement of the spray head 150 on the arcuate track 130 according to an embodiment. Some of the previously labeled mechanical components are not relabeled in these figures to avoid clustering. Figure 6A shows the spray head 150 moving to the left end of the arcuate track 130, and Figure 6B shows the spray head 150 moving to the right end of the arcuate track 130. Further, Figures 6A and 6B also show the radial movement of the spray head 150 (indicated by the dashed outline of the spray head 150). Also, as shown in Figures 1 and 2, the spray head 150 is mounted on top of the track connector 140 and can slide along with the track connector 140 along the arcuate track 130 by lateral movement. The spray head 150 can move along the arcuate track 130 to track the contour of the face and completely cover the user's face.

[0041] Figures 7A and 7B show the rotational movement of the spray cartridge 250 according to an embodiment. Some of the previously labeled mechanical components are not relabeled in these figures to avoid clustering. Figure 7A shows the spray cartridge 250 rotating counterclockwise, and Figure 7B shows the spray cartridge 250 rotating clockwise. As described above, the rotation of the spray cartridge can increase the angular range of the spray over the target area. Further, by rotation, different nozzles 152 of the spray cartridge 250 can be selected to spray. Further, Figures 7A and 7B also show arrows indicating the radial movement along the linear track 145 of the spray head 150 and the lateral movement along the arcuate track 130.

[0042] In one embodiment, a machine-readable code (e.g., barcode, QR code (registered trademark), radio frequency identifier (RFID), etc.) may be printed on the outer surface of the spray cartridge 250 (Figure 2).

[0043] The code identifies the type and color of the liquid stored within the speaker cartridge 250. The code can also be used for validation or security purposes, for example to prevent counterfeiting, or for warning purposes such as to warn the user of the expiration date of the liquid.

[0044] In one embodiment, the speaker cartridge 250 is modular. That is, the speaker cartridge 250 is assembled by a plurality of individual compartments, and any compartment may be removed from the cartridge and exchanged with another compartment. Each compartment may have a machine-readable code (e.g., barcode, QR code, RFID, etc.) printed on its surface to identify the type or color of the liquid stored within this compartment. The machine 100 can check the code on each compartment to determine whether the correct compartments have been assembled into the modular speaker cartridge (e.g., for the makeup template selected by the user) and can inform the user. The code on each compartment can also be used for validation or security purposes, for example to prevent counterfeiting in any compartment, or for warning purposes such as to warn the user of the expiration date of the liquid in any compartment.

[0045] FIG. 8 is a diagram showing a machine 100 having a circuit for reading a machine-readable code on a speaker cartridge 250 according to an embodiment. Also, as shown in FIG. 2, the main body 110 has an upper cover 230 having a front portion raised in front of the arcuate track 130. Also, as described above with reference to FIG. 2, the front bottom surface of the speaker cartridge 250 is exposed through the front opening 251 of the spray head 150. A machine-readable code may be printed on the exposed surface of the speaker cartridge 250. When the spray head 150 moves forward on the linear track 145 (e.g., toward the user's face), the exposed surface of the speaker cartridge 250 overlaps with the front portion of the upper cover 230. In one embodiment, this overlapping portion includes an upward imaging circuit 810 (e.g., a camera, scanner, etc.) for reading the machine-readable code printed on the speaker cartridge 250. In an alternative embodiment, the bottom surface of the spray head 150 has a bottom window through which the machine-readable code printed on the bottom of the speaker cartridge 250 is exposed. The imaging circuit 810 reads the machine-readable code for identification purposes including, but not limited to, the above-described verification, authentication, security, and warning purposes. In embodiments where the speaker cartridge 250 is modular, each section of the speaker cartridge 250 may have a machine-readable code printed on the bottom surface. The speaker cartridge 250 may rotate so that the imaging circuit 810 can read the code on each section of the speaker cartridge 250, e.g., one section at a time.

[0046] FIG. 9 is a diagram showing a machine 100 having a circuit for reading a machine-readable code on a speaker cartridge 250 according to another embodiment. In this embodiment, the circuit is a scanner 910 integrated into an upper lid 255 of a spray head 150. The scanner 910 may be positioned at a position corresponding to a code printed on the speaker cartridge 250. In an embodiment where the speaker cartridge 250 is modularized, each section of the speaker cartridge 250 may have a machine-readable code printed on a surface that can be read by the scanner 910. The speaker cartridge 250 may rotate so that the scanner 910 can read the codes on each section one at a time. In an embodiment where the scanner 910 is an RFID reader, the machine-readable code is an RFID embedded in the speaker cartridge 250. Since the RFID can be read without line of sight, the RFID reader may be positioned anywhere within the machine 100, such as inside the main body 110, the side arm 120, the spray head 150, or on the surface of the machine 100.

[0047] FIG. 10 shows a makeup machine 300 according to another embodiment. In this embodiment, the machine 300 includes an arch-shaped structure, and the arch-shaped structure further includes an arch-shaped track 330 on top of an arch-shaped base 335. A spray head 350 is mounted on top of the arch-shaped track 330. The spray head 350 moves along the arch-shaped track 330 to track the contour of a target area such as a user's face. The spray head 350 has a front window 351 through which the skin spray passes.

[0048] The spray head 350 includes a container that receives a speaker cartridge such as the speaker cartridge 250 of FIG. 2. In the example of FIG. 10, the upper lid of the spray head can be opened to receive the speaker cartridge. In another embodiment, the speaker cartridge may be inserted into a slot on the side of the spray head 350. The front window 351 of the spray head 350 is open up to the nozzle of the speaker cartridge. In one embodiment, to finely adjust the spray aim, the spray head 350 may rotate the speaker cartridge to adjust the nozzle position within the front window 351. In an embodiment where the speaker cartridge has a plurality of nozzles around it, the spray head 350 may rotate the speaker cartridge to select and spray different nozzles.

[0049] The machine 300 includes a main body 310 that provides a housing for a control circuitry, a motor, and an air supply source for the operation of the spray head 350 in some embodiments. In this example, the front side of the main body 310 has a concave upper surface 311 and a concave lower surface 312. However, it is understood that the main body 310 may have a shape different from that shown.

[0050] Machine 300 includes a linear track 345 disposed on top of the main body 310. Similar to machine 100 (FIG. 1), the linear track 345 is used to adjust the horizontal distance between the spray head 350 and the user's face. Different from machine 100, the spray head 350 is not mounted on the linear track 345, and the linear track 345 does not move with the spray head 350. The linear track 345 stays on the horizontal center line of the arch structure during the operation of the machine. To position the spray head 350 at a predetermined horizontal distance from an object (e.g., the user's face), the length of the linear track 345 is adjustable by a control circuit. The linear track 345 extends to move the arch structure further away (i.e., in the distal direction) and contracts to move the arch structure closer to the user (i.e., in the proximal direction), and the arch structure includes both an arched track 330 and an arched base 335. The movement of the linear track 345 may be driven by a motor within the main body 310.

[0051] In one embodiment, the proximal end of the linear track 345 is connected to the rear piece 362 of the jaw support 360, and the distal end is connected to the arched base 335. Since the arched base 335 and the arched track 330 move tandemly and the spray head 350 is mounted on the arched track 330, the movement of the linear track enables the proximal-distal movement of the spray head 350. Machine 300 can utilize this proximal-distal movement to adjust the horizontal distance between the spray head 350 and the user's face.

[0052] The linear track 345 can provide a passage for an electrical cable that connects a control circuit or a motor to adjust the positions of the spray head 350 and the speaker cartridge. In one embodiment, the linear track 345 can also provide a passage for an air pipe to deliver compressed air from an air source such as an air tank or an air pump to the speaker cartridge.

[0053] In one embodiment, the jaw support 360 includes a rear piece 362 and a front piece 361. The rear piece 362 remains stationary when the linear track 345 expands and contracts. The front piece 361 is where the user's jaw is placed. The front piece 361 is adjustable vertically. For example, the front piece 361 can be raised to position the user's jaw at an appropriate height relative to the spray head 350.

[0054] FIG. 10 also shows a gap 380 near the lower end of the main body 310. The gap 380 allows a belt or rod to connect the left and right sides of the arched base 335, so that both sides can synchronize the vertical movement of the arched track 330. The vertical movement will be described later with reference to FIG. 16. The belt or rod moves with the arched base 335. The arched base 335 may include two motors (or one stepping motor on one side and one actuator on the other side) on both the right and left sides to drive the vertical movement.

[0055] FIG. 10 also shows a camera and / or sensor 390 in front of the spray head 350 for capturing a 3D image of the user. In one embodiment, a light curved along the forward surface of the arched track 330 may be arranged to illuminate the user's face (for example, for photography and other operations). In one embodiment, the light may be arranged on the concave upper surface 311 of the main body 310 under the jaw support 360. Although not shown in FIG. 10, speakers may be arranged inside the arched base 335 (both on the left and right sides) or other parts of the machine 300 to optimize acoustics. A wireless interface (e.g., Bluetooth®, Wi-Fi®, etc.) may also be provided to connect the machine 300 and / or the speakers to a network or the user's mobile phone. Although not shown in FIGS. 1 - 9, it is understood that the machine 100 may also have a camera and / or sensor in front of the spray head 150, a light on the forward surface of the arched track 130, and a light on the upper surface of the main body 110.

[0056] Machine 300 also provides an observation surface 370 similar to the observation surface 170 of FIG. 1. In the following description with reference to FIGS. 11 to 17, the observation surface 370 is omitted for simplicity of illustration.

[0057] The linear track 345 stays on the horizontal center line and has a horizontal length adjustable by a controller circuit to position the spray head at a predetermined horizontal distance from the object. FIG. 11 shows an arch-shaped structure in a fully retracted position according to one embodiment. The linear track 345 is retracted in the proximal direction, moving the arch-shaped structure and the spray head 350 thereon towards the user. In this position, the front end of the arch-shaped base 335 can be in the same plane as the front side of the main body 310. FIG. 12 shows an arch-shaped structure in an extended position according to one embodiment. The linear track 345 extends in the distal direction, moving the arch-shaped structure and the spray head 350 thereon away from the user. In one embodiment, machine 300 includes a motor that drives the expansion and contraction of the linear track 345 under the arch-shaped track 330 behind the jaw support 360.

[0058] FIGS. 13 and 14 show the lateral movement of the spray head 350 on the arch-shaped track 330 according to one embodiment. Some of the previously labeled machine components are not relabeled in these figures to avoid clustering. FIG. 13 shows the spray head 350 moving to the left end of the arch-shaped track 330, and FIG. 14 shows the spray head 350 moving to the right end of the arch-shaped track 330. The spray head 350 is installed on a track connector 340 that connects the spray head 350 to the arch-shaped track 330. The track connector 340 may house one or more motors that move the spray head 350 across the arch-shaped track 330 and / or rotate the spray cartridge within the spray head 350.

[0059] FIG. 15 shows the vertical movement (e.g., upward movement) of the arch-shaped track 330 and the spray head 350 according to one embodiment. In one embodiment, the arch-shaped track 330 is supported by two side columns 410 extending from the arch-shaped base 335. The columns 410 can extend upward from the arch-shaped base 335 to cover the full height of the head. The two columns 410 can move up and down synchronously in the vertical direction by a belt or rod within a gap 380 (FIG. 10) connecting the two columns 410. In this example, for providing stability, the columns 410 are attached to the bottoms of both the right and left sides of the arch-shaped track 330. When the columns 410 are retracted to lower the arch-shaped track 330, the retracted portions of the columns 410 are hidden from the user (e.g., inside the arch-shaped base 335) and do not take up space. It is understood that the columns 410 are an example of a vertical support for adjusting the height of the arch-shaped track 330 and the spray head 350, and alternative embodiments of the vertical support are described in relation to the column 210 in FIG. 4.

[0060] FIG. 16 shows the arch-shaped track 330 lowered to be positioned above the upper part of the arch-shaped base 335 according to one embodiment. FIGS. 16 and 17 also show that the front piece 361 of the jaw support 360 has an adjustable height (indicated by the double-sided arrows of the dotted line in FIG. 16). In FIGS. 10-16, the front piece 361 of the jaw support 360 is in the raised position. FIG. 17 shows the front piece 361 lowered to the same height as the rear piece 362. As described above, the height of the front piece 361 is adjustable up and down. For example, the front piece 361 can be raised to position the user's jaw at an appropriate height relative to the spray head 350. The front piece 361 may have an embedded sensor that detects whether the user's jaw is on the jaw support 360 and, as a safety function, can stop the operation of the machine if the user suddenly leaves.
