Description

Rotating drum with comb-like movement

[0001] The present invention relates to a rotating drum in which a comb moves in and out, and more specifically, to a rotating drum in which a plurality of combs arranged along the outer surface of a rotating drum perform periodic in and out movements in a direction perpendicular to the height direction of the drum simultaneously with the rotation of the drum, thereby enabling effective separation and removal of tangled hair or foreign matter.

[0002] Rotary brushes have been widely used for grooming or cleaning animal fur, and are particularly advantageous for aligning the fur and maintaining cleanliness by combing the furry areas in a consistent direction.

[0003] However, in conventional rotary brushes, loose hair or thread-like debris gets tangled in the bristles, making it difficult to remove, and there is the inconvenience of having to manually pull the hair to remove it.

[0004] To improve this inconvenience, a slicker brush structure combined with an air intake was developed, but this structure also has structural limitations in that it is difficult to operate continuously while in contact with the application area and cannot immediately remove tangled foreign matter.

[0005] In particular, due to the lack of technology that simultaneously satisfies real-time operation and foreign matter removal at the application site, there is a need for the development of a high-performance brush that integrates a rotating brush and a foreign matter removal function.

[0006] Accordingly, a structure was required in which the comb mounted on the drum does not simply rotate, but performs periodic inward and outward movement in the horizontal direction relative to the central cylinder diameter of the drum in conjunction with the rotation of the drum, thereby moving foreign matter caught in the comb to a specific location outside the drum and enabling automatic removal.

[0007] Furthermore, by applying this mechanism to vacuum cleaner heads, pet brushes, hair dryers, etc., there is a need for a foundation to develop it into a multifunctional device capable of removing foreign substances and drying simultaneously with brushing.

[0008] Meanwhile, the aforementioned background technology is technical information that the inventor possessed for the derivation of the present invention or acquired during the process of deriving the present invention, and it cannot necessarily be considered publicly known technology disclosed to the general public prior to the filing of the present invention.

These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention. It should be understood that various embodiments of the invention are different but need not be mutually exclusive.

Similar reference numerals in the drawings refer to the same or similar functions across various aspects.

[0053] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.

[0054] FIG. 1 is a diagram illustrating the schematic configuration and operating principle of a rotating drum in which a comb moves in and out according to one embodiment of the present invention.

[0055] Referring to FIG. 1, a rotating drum in which a comb moves in and out according to one embodiment of the present invention includes a drum (100) and a comb structure (200).

[0056] The drum (100) is formed with a structure capable of rotational movement and provides an internal space while rotating along its outer surface. The drum (100) rotates clockwise. The interior is formed hollow so that various driving mechanisms can be installed inside even while rotating.

[0057] The drum (100) is provided with a comb opening (140) on its outer surface, and these openings serve as passages for the comb structure (200) to enter and exit.

[0058] A drum (100) according to one embodiment of the present invention having the configuration as described above forms a structural base in which the comb (220) of the comb structure (200) can be exposed to the outside or stored when the drum (100) rotates by providing an access path to the comb (220).

[0059] The comb (220) is positioned to move in and out through the comb entrance (140) of the drum (100) and performs periodic movement in and out according to the rotation of the drum (100). The comb (220) is configured to be exposed to the outside through the entrance (140) or to be drawn into the inside of the drum (100).

[0060] The comb structure (200) is rotatably connected at its end to a device inside the drum (100), so that it can perform a reciprocating movement in the horizontal direction simultaneously with the rotation of the drum (100). This reciprocating movement is repeated in synchronization with the rotation of the drum (100), thereby providing the effect of filtering out foreign matter or hair from the surface of the object to be cleaned and transporting it to a specific location.

[0061] A comb (220) according to one embodiment of the present invention having the configuration described above is configured to perform periodic movement in and out through the comb opening (140) of the drum (100) while the drum (100) is rotating, thereby allowing foreign matter to be transported to or removed to the outside without entanglement during continuous combing operations, and improving the reliability and convenience of the automated cleaning and combing function.

[0062] A rotating drum having a comb moving in and out according to one embodiment of the present invention having the configuration described above can implement an active rotating brush device that prevents foreign substances from getting tangled in the comb and effectively transports foreign substances to the outside even during continuous brushing, by precisely synchronizing the rotation of the drum (100) and the movement of the comb (220) in and out, thereby preventing foreign substances from getting tangled in the comb.

[0063]

[0064] Referring to FIG. 2, a rotating drum (10) in which a comb moves in and out according to one embodiment of the present invention may include a cam device (400).

[0065] The cam device (400) is configured to be positioned in an eccentric state, spaced apart from the rotational center axis of the drum (100) by a predetermined distance.

[0066] The cam device (400) can be designed to induce asymmetric rotation or linear motion with respect to a central axis while being synchronized with the rotational motion of the rotating drum (100).

[0067] This eccentric arrangement allows the mechanical thrust acting on the comb (220) to be variably adjusted, thereby inducing the comb's movement to be periodic and dynamic.

[0068] The cam device (400) is mounted on the inner or outer side of the drum (100) and can perform the function of precisely controlling the direction of entry and exit and the spacing of the comb (220) placed inside the drum (100) by the rotation or eccentric rotation of the cam.

[0069] Accordingly, the cam device (400) can contribute to providing a more sophisticated and repeatable mechanical motion pattern than the entry and exit of the comb according to simple rotational motion.

[0070] A rotary drum having a comb moving in and out according to one embodiment of the present invention, having the configuration described above, includes a cam device (400) eccentrically arranged therein, thereby providing the effect that the movement of the comb (220) moving in and out can be performed in a more precise and predictable manner according to the rotational movement of the drum (100).

[0071] In addition, the entry depth, protrusion angle, and operation timing of the comb can be finely adjusted by cam action inside or outside the drum (100), so it has the advantage of enabling customized operation suitable for the characteristics of the target material.

[0072]

[0073] A rotary drum in which a comb moves in and out according to one embodiment of the present invention having the configuration described above is driven as follows.

[0074] The cam device (400) is configured to be eccentric with respect to the rotational center axis of the drum (100) so as to induce irregular motion according to the shape change of the cam when the drum (100) rotates or drives.

[0075] This cam device (400) can perform the function of transmitting repetitive and periodic displacement motion to connected components due to its eccentric structure while rotating or vibrating by rotational power or external driving force.

[0076] The entry / exit motion axis is positioned in contact with the outer part or cam surface of the cam device (400) and is configured to perform reciprocating motion in the up-down or forward-backward direction according to the rotational shape of the cam.

[0077] This movement axis can move along the height change or protrusion of the cam and perform the function of pushing the comb (220) installed on the drum (100) outward or pulling it inward.

[0078] Accordingly, the entry / exit motion axis performs linear or curved motion that is precisely controlled by the geometric shape and motion pattern of the cam device (400).

[0079] The comb (220) can repeatedly perform an in-and-out movement by protruding outward or being inserted inward through the comb openings (140a, 140b) formed on the outer surface of the drum (100) according to the linear reciprocating movement of the in-and-out movement axis.

[0080] Through this structure, the comb (220) is driven actively rather than passively by the rotation of the drum (100) and the operation of the cam device (400), so that it can perform mechanical actions such as precise scraping, conveying, and removal on the target material.

[0081] A rotary drum having a comb that moves in and out according to one embodiment of the present invention having the configuration described above provides the effect of being usefully applicable to a rotary drum (100) device that requires repetitive and precise operation, by means of the interlocking action of a cam device (400) eccentrically disposed on the drum (100) and a shaft receiving action therefrom, so that the comb (220) periodically moves in and out of the drum (100).

[0082] In addition, this cam-based operating structure can implement non-linear or multi-stage entry and exit patterns that are difficult to achieve in simple rotary drum systems, offering the advantage of maximizing application possibilities across various industries.

[0083]

[0084] At this time, the comb entrance (140a, 140b) is configured so that one or more combs (220) can enter and exit in each.

[0085] The comb entrance (140a, 140b) is formed on the outer surface of the drum (100) and functions as a passage through which the comb (220) protrudes outward or is inserted inward.

[0086] Typically, a single comb is arranged in one comb opening (140a, 140b), but in the present invention, two or more combs (220) may be configured to correspond to one opening.

[0087] Multiple comb teeth (220) perform entry and exit movements simultaneously or alternately through the same entrance, which enables a denser scraping or contact motion.

[0088] Additionally, the multiple combs (220) may be operated in conjunction by the same driving mechanism, or each may be operated by an independent driving or elastic return means.

[0089] This configuration allows for the formation of more contact points through a single entrance, thereby increasing the density of the comb even in narrow spaces, and as a result, can improve the precision and processing capacity of sorting, scraping, and conveying operations.

[0090] In particular, since multiple combs can operate even with a small number of openings, it also provides design advantages such as simplification of the structure of the outer surface of the drum (100) and increased space utilization.

[0091] A rotary drum having a comb moving in and out according to one embodiment of the present invention having the configuration described above is configured so that one or more combs (220) can move in and out through one comb opening (140a, 140b), thereby increasing the comb density within the same area and consequently providing an advantageous effect of improving the work efficiency and contact precision of the device.

[0092] In addition, through the cooperative action of multiple combs, it is possible to implement more complex or diverse patterns of operation than existing structures, making it highly useful in high-performance sorting or separation processes.

[0093]

[0094] FIGS. 2(a) and (b) are drawings illustrating the schematic configuration of a rotating drum in which a comb moves in and out according to a first embodiment of the present invention.

[0095] Referring to FIG. 2, a rotating drum (10) in which a comb moves in and out according to one embodiment of the present invention includes a rotating drum (100) and a comb (220).

[0096] The drum (100) is configured to rotate along its outer surface in a circular shape and is connected to a cam device (400) described later to perform rotational movement in a certain direction. At this time, the drum (100) forms a space inside and is designed so that various operating mechanisms or connecting devices can operate within this space. A plurality of openings (i.e., a first comb entrance (140a), a second comb entrance (140b)) are provided on the outer surface of the drum (100), and each opening acts as a passage for the comb (220) to enter and exit.

[0097] In one embodiment, the drum (100) may include a drum gear (120), a drum cylinder (130), a first comb opening (140a), and a second comb opening (140b).

[0098] The base plate (300) provides a surface on which the rotation axis of the drum cylinder (130) can be fixed.

[0099] The drum gear (120) is configured in the shape of a circular ring and is installed to rotate by fixing the rotation axis to the base plate (300) in conjunction with the drum cylinder (130). It performs power transmission by engaging with the cam device (400) or the drive gear through the first gear (121) formed along the inward surface. The drum gear (120) is precision machined around the central axis to enable smooth rotation without loss of rotational force and is configured to rotate together with the drum cylinder (130).

[0100] The drum cylinder (130) is formed in a cylindrical shape and is installed on the upper side of the drum gear (120) so as to rotate together in synchronization with the rotation of the drum gear (120). The drum cylinder (130) is a rotating body and has a plurality of openings on its outer surface (i.e., a first comb opening (140a) and a second comb opening (140b)), and is designed so that the comb (220) can be inserted and withdrawn.

[0101] The first comb entrance (140a) is a passage formed in the drum cylinder (130) such that one side of the comb (220) is exposed to the outside. This entrance is a section where the rotation of the drum cylinder (130) and the movement of the comb (220) occur simultaneously, and it is a position where the comb (220) comes into direct contact with the object to be cleaned.

[0102] The second comb opening (140b) is formed in the drum cylinder (130) opposite to the first comb opening (140a), so that the other side of the comb (220) is exposed to the outside. The two openings are configured so that both ends of the comb (220) can advance from inside the drum to the outside, so that the entire comb (220) is exposed to the outside during rotation and movement, allowing foreign matter to be easily removed or collected.

[0103] A drum (100) according to one embodiment of the present invention having the configuration described above can have a drum gear (120) rotatably installed on a base plate (300), a drum cylinder (130) coupled to the upper side of the drum gear (120), and first and second comb entry / exit ports (140a, 140b) formed at both ends so that both sides of the comb (220) can be freely exposed to the outside and the movement of the comb (220) can be accurately performed in conjunction with the rotation of the drum cylinder (130), thereby increasing the structural completeness of the device and the precision of the combing function.

[0104] A drum (100) according to one embodiment of the present invention having the configuration described above is stably supported through a base plate (300) as shown in FIG. 2 (b), and the movement of the comb teeth can be precisely controlled by eccentric rotation and gear coupling through a cam device (400), thereby improving the integral operation of the rotating drum and enabling efficient combing and removal of foreign substances.

[0105] The comb (220) is installed along the first comb opening (140a) and the second comb opening (140b) arranged on the outer surface of the drum (100), and performs an in-and-out movement synchronized with the rotation of the drum (100). The comb (220) is arranged at regular intervals and reciprocates in the forward and backward directions by a driving element, such as an eccentric device, an elastic body, or a cam structure installed inside the drum while the drum (100) rotates. This in-and-out movement occurs periodically and repeatedly in conjunction with the rotation of the drum (100), and as a result, the comb (220) can filter out foreign matter or loose hair after contacting the object to be cleaned or combed, and move it from the outside of the drum to a specific location inside through the in-and-out movement.

[0106] In one embodiment, the comb (220) is positioned so that one end and the other end are exposed to the outside of the drum (100), and the middle end is rotatably connected to the cam device (400).

[0107] The comb (220) is arranged along the longitudinal direction and is exposed to the outside by allowing both ends to pass through the drum (100) via the first comb opening (140a) and the second comb opening (140b), thereby forming an active working part capable of contacting the object to be cleaned or combed. Each comb (220) is formed of an elastic material or a high-strength material so as to absorb mechanical stress caused by repetitive movement while maintaining shape stability.

[0108] The middle section (210) of the comb (220) is rotatably connected to the cam device (400) in the internal space of the drum (100). This connection (210) can be implemented in the form of an axial connection, a pin connection, or a oscillating shaft, and as the cam device (400) rotates, the middle section of the comb (220) oscillates, thereby inducing the entire comb to advance or retract in a horizontal direction. In particular, since the cam device (400) has an eccentric structure, it pushes or pulls the middle section of the comb (220) along a certain rotational trajectory, thereby implementing an inward and outward movement of protrusion to the outside or retraction to the inside.

[0109] The movement of entering and exiting reciprocates in a horizontal direction relative to a plane perpendicular to the longitudinal direction of the drum (100) and occurs repeatedly in synchronization with the rotation of the drum (100). As a result, the comb teeth (220) perform a horizontal reciprocating motion simultaneously with rotation, and can naturally transport foreign matter caught during combing to a specific point or prevent it from getting tangled in the hair.

[0110] A comb (220) according to one embodiment of the present invention having the configuration described above has both ends positioned to be exposed to the outer circumference of a drum (100), and a middle section (210) is rotatably connected to a cam device (400) to perform an in-and-out movement in the horizontal direction according to the rotation of the cam device, thereby realizing an active mechanism that enables automatic removal of foreign matter and continuous combing without complex operation.

[0111] A rotating drum (10) having a comb that moves in and out according to one embodiment of the present invention having the configuration described above, by having a plurality of combs arranged along the outer surface of the rotating drum perform synchronized moving in and out movements when rotating, so that hair or foreign matter is naturally transported to a specific location and removed without getting tangled in the combs, thereby enabling continuous combing and cleaning operations, and can dramatically improve user convenience and the cleanliness maintenance performance of the device.

[0112]

[0113] A rotating drum (10) having a comb-like movement according to one embodiment of the present invention having the configuration described above may include a base plate (300) and a cam device (400).

[0114] The base plate (300) is a structure that supports the drum (100) from below to enable rotation, and is combined with the drum gear (120) to ensure the mechanical stability of the entire system. The base plate (300) acts as a point where a support shaft for the rotation of the drum (100) is installed, and may include an axis support member, a bearing, or a rotation support member so that the drum (100) can rotate smoothly along the rotation center axis.

[0115] The cam device (400) is rotatably connected to the top of the base plate (300) and positioned eccentrically on the inside of the drum (100). The cam device (400) rotates in engagement with the drum (100) by means of gear coupling, thereby inducing rotational movement of the drum (100) while simultaneously controlling the movement of the comb (220). That is, the cam device (400), in addition to the rotational force transmission function, causes the comb (220) to protrude outward or be drawn into the drum (100) at a specific rotation angle according to the eccentric structure.

[0116] The cam device (400) may be composed of a drive shaft, a gear section, an eccentric shaft, a roller, or a pushing projection, and is designed to contact or interlock with the comb (220) inside the drum (100) to enable periodic movement. In particular, interlocking through gear coupling enables smooth power transmission between the cam device (400) and the drum (100) without mechanical interference, thereby increasing the operational reliability of the system.

[0117] In one embodiment, the cam device (400) may include a cam shaft (410), a cam gear (420), a cam (430), and an entry / exit motion shaft coupling part (440).

[0118] The camshaft (410) is positioned inside the base plate (300) and is installed upright so as to be rotatable, eccentrically spaced from its center. The camshaft (410) rotates, and this rotational motion is transmitted to the drum gear (120) through the cam gear (420). The camshaft (410) can be connected to a drive shaft or an external power source and functions as the rotational center axis of the entire cam device (400).

[0119] The cam gear (420) is axially coupled to the cam shaft (410) and rotates together with it, and is installed to mesh with the first gear (121). This gear is positioned at the lower end of the cam shaft (410) and rotates simultaneously with the rotation of the cam shaft (410) to drive the drum gear (120). The gear teeth of the cam gear (420) and the drum gear (120) mesh with each other to smoothly transmit rotational force, thereby realizing mechanical synchronization between the cam device (400) and the drum (100).

[0120] The cam (430) is installed on the cam shaft (410) exposed above the cam gear (420) and rotates integrally with the cam shaft by means of shaft coupling. The cam (430) can be formed in a circular or eccentric circular shape on a flat surface and is configured to be coupled with the comb when rotating. At this time, the cam (430) is structured to be coupled with the entry / exit motion axis (210) of the comb (220) and is a core component of entry / exit motion control that induces the comb (220) to advance or retract according to a change in position at a certain angle.

[0121] The entry / exit motion axis coupling part (440) is formed on the surface or outer circumference of the cam (430) and allows the entry / exit motion axis (210) of the comb (220) to be inserted and installed. Since this entry / exit motion axis coupling part (440) is formed eccentrically from the center of the cam (430), as the cam (430) rotates, the entry / exit motion axis (210) of the comb (220) also repeatedly reciprocates along the trajectory of the cam (430). This has a structural feature that allows horizontal entry / exit motion to be realized through displacement on the rotational trajectory while being positioned to pass through the rotational centerline (S) of the drum cylinder (130).

[0122] A cam device (400) according to one embodiment of the present invention having the configuration described above comprises an eccentrically installed cam shaft (410), a cam gear (420) coupled thereto, a cam (430), and an entry / exit motion shaft coupling part (440) into which the rotation axis of the comb is inserted, thereby enabling the comb (220) to perform periodic and precise entry / exit motion based on the rotation center of the drum cylinder (130), and by concisely implementing the entry / exit mechanism using only an internal cam structure without external power, it can contribute to miniaturization, weight reduction, and improved durability of the device.

[0123]

[0124] In one embodiment, the comb (220) can move in and out in the left and right horizontal directions through the first comb opening (140a) and the second comb opening (140b) as the cam (430) rotates inside the drum cylinder (130).

[0125] The comb (220) has its entry / exit axis (210) connected to the entry / exit axis coupling part (440) of the cam (430) so as to be linked to the rotational movement of the cam (430), and is configured to perform oscillating or reciprocating movement based on a certain radius according to the movement method of the cam (430). At this time, the cam (430) is placed inside the drum cylinder (130) and receives rotational force through gear coupling with the drum gear (120).

[0126] The rotation of the cam (430) is induced by mechanical engagement with the drum gear (120) or the external drive gear, and in this process, the entry / exit movement axis (210) of the comb (220) inserted into the entry / exit movement axis coupling part (440) reciprocates horizontally along a geometric trajectory. This movement is realized in such a way that both ends of the comb are alternately exposed to the outside through the first comb entry / exit (140a) and the second comb entry / exit (140b) of the drum cylinder (130) and then retracted back inside.

[0127] As a result, the comb (220) repeatedly performs periodic movement in the left and right directions by the rotation of the cam (430), and since this movement occurs simultaneously with the rotation of the drum, it is possible to induce the natural removal of foreign matter caught on the comb (220) even during continuous combing operations. In particular, the rotation of the drum cylinder (130) and the movement of the comb (220) are designed to be precisely synchronized, thereby providing a stable combing environment without entanglement or jamming of foreign matter.

[0128] A comb (220) according to one embodiment of the present invention having the configuration described above can effectively separate and remove long hair or foreign matter tangled in the comb (220) by realizing repetitive horizontal movement around the two entrances of the drum cylinder (130) through a complex movement according to the rotation of the cam (430), and in particular, provides a technical advantage of maximizing the maintainability and efficiency of the comb function even under a continuous and automated operating environment.

[0129]

[0130] In one embodiment, the drum (100) may be installed so that the direction of rotation can be changed.

[0131] The drum (100) is a cylindrical structure that is rotated by an external power source, and has a plurality of comb entry / exit ports (140a, 140b) formed on its outer surface, and is equipped with a mechanism inside to guide the entry and exit of the comb (220).

[0132] Conventional rotating drums (100) are typically configured to rotate in only one direction, but a drum (100) according to one embodiment of the present invention is installed to switch the rotation direction to forward and reverse directions.

[0133] Such rotational direction change can be realized, for example, by controlling the driving direction of a motor, a selective reversal mechanism of a reduction gear, or by a bidirectional rotatable bearing and a power transmission device.

[0134] When the rotation direction of the drum (100) is changed, the direction or timing of the internal comb (220) protruding and being inserted through the comb entrance (140a, 140b) may change, and accordingly, various operating patterns and corresponding target materials are possible.

[0135] The rotation direction switching function can be advantageous for removing foreign matter by reversing rotation when it gets stuck inside or outside the drum (100), or for effectively removing an object by reversing the friction direction of the comb.

[0136] In addition, the movement of the comb teeth can be controlled more precisely through a combination of forward and reverse operation, making it useful in processes requiring complex operations.

[0137] A rotating drum having a comb that moves in and out according to one embodiment of the present invention, having the configuration described above, is installed so that the drum (100) can change the direction of rotation, thereby providing the effect of diversifying the operating pattern of the comb and flexibly adjusting the removal method or directionality of the target material.

[0138] As a result, compared to a single-direction rotating drum (100), it has the advantage of improving work flexibility and enabling the realization of a multi-functional rotating drum (100) structure that can respond to various situations.

[0139]

[0140] In one embodiment, the comb (220) can be installed to vibrate regardless of the rotation of the drum (100).

[0141] The comb (220) is configured to perform an in-and-out movement through comb openings (140a, 140b) formed on the outer surface of the drum (100), and conventionally, an in-and-out method was generally induced by relying on the rotation of the drum (100).

[0142] However, in the present invention, the comb (220) itself is configured to vibrate independently of the rotation of the drum (100), thereby enabling a new operating mechanism.

[0143] This vibrating structure can be implemented, for example, through a separate vibration module, solenoid, piezoelectric actuator, or electromagnetic unit connected to the comb (220).

[0144] The vibration drive unit is driven independently regardless of whether the drum (100) rotates, and rapidly vibrates the comb in the up-down, forward-backward, or left-right directions, thereby enabling fine work that is difficult to achieve with only the rotation of the drum (100).

[0145] With this structure, the comb (220) repeatedly performs individual vibrational motion regardless of the rotation of the drum (100), and thus can effectively remove stuck foreign matter or separate an object attached to the surface.

[0146] In addition, since specific tasks can be performed using only comb vibration even when the drum (100) is stationary, it is advantageous in terms of energy saving and driving efficiency.

[0147] A rotary drum having a comb that moves in and out according to one embodiment of the present invention, having the configuration described above, is installed so that the comb (220) can vibrate independently of the rotation of the drum (100), thereby enabling separate precision work through vibration without relying on the rotation of the drum (100), and by implementing a complex motion structure, it provides the advantage of being flexibly utilized in various industrial environments.

[0148] In addition, micro-movements caused by vibration enable effective removal and cleaning operations while minimizing product damage, which can contribute to producing high-quality results.

[0149]

[0150] A rotating drum having a comb that moves in and out according to one embodiment of the present invention having the configuration described above may further include a case (500) as shown in FIGS. 3 and 4.

[0151] The case (500) is installed near the central axis or inner circumference of the drum (100) and serves as a housing that protects or functionally integrates the internal operating system of the drum (100).

[0152] This case (500) may be made of a rigid material or a composite material having insulation, heat dissipation, and shock absorption functions, and performs the function of protecting and aligning the moving elements generated inside from the outside when the drum (100) rotates.

[0153] The case (500) is not limited to a simple protective structure, but can function as a structure that accommodates and supports various components such as a cam device (400) that drives the comb (220), an entry / exit motion axis, a vibration unit, and a return spring.

[0154] In addition, this case (500) is formed in the shape of a head at the center of the drum (100) and can be aligned with the rotation axis of the drum (600) or mounted in the up-down and forward-backward directions to promote integration of the entire head part.

[0155]

[0156] Such a case (500) can contribute to improving the mechanical stability of the internal structure and ensuring the durability and maintainability of the entire device.

[0157] In addition, it enables precise positional alignment between components, thereby increasing the accuracy and repeatability of entry and exit movements, and simplifies inspection and parts replacement by allowing detachment and reattachment on a case-by-case basis during maintenance.

[0158] A rotary drum having a comb that moves in and out according to one embodiment of the present invention, having the configuration described above, comprises a case (500) installed inside the drum (600) to form a head, thereby enhancing the alignment and protection functions of the internal drive structure and providing the advantage of simultaneously realizing various effects such as maintenance, maintainability, and ease of assembly of the device through a modular head structure.

[0159]

[0160] In one embodiment, the case (500) may include protrusions (510a, b, c) to block part of the air passage inside, as shown in FIG. 3.

[0161] The case (500) is positioned inside the drum (100) and serves as a housing that accommodates and supports internal components, while additionally having a functional structure for controlling airflow.

[0162] In particular, in this embodiment, a protrusion (510a, b, c) structure is formed inside the case (500) and can perform the function of intentionally restricting or changing a portion of the passage of air circulating inside the device.

[0163] The corresponding protrusions (510a, b, c) are formed at specific parts of the air flow path and serve to control the speed, pressure, and flow direction of the air, or to prevent dust and foreign substances inside from concentrating in specific spaces.

[0164] In addition, the structure of these protrusions (510a, b, c) is not a simple blockage, but is designed with an aerodynamically optimized protruding shape, which can help maintain the airflow balance of the entire system.

[0165] The protrusions (510a, b, c) inside the case can, for example, affect the heat exhaust path or filtering space generated inside the drum (100), thereby inducing airflow and simultaneously blocking or dispersing some pressure, which can improve the stability and durability of the internal structure.

[0166] Additionally, the protrusions (510a, b, c) can perform functions such as protecting a specific space where a sensor or filter module is located or blocking interference caused by unnecessary airflow.

[0167] At this time, the protrusions (510a, b, c) may be formed as fixed protrusions (510a), variable protrusions (510b), cutting blade-type protrusions (510c), etc., as needed.

[0168] A rotary drum having a comb-like structure according to one embodiment of the present invention, having the configuration described above, includes protrusions (510a, b, c) for blocking a part of the air passage inside the case (500), thereby providing a technical effect that allows for precise control of the airflow inside the device and simultaneously ensures the stability and operational efficiency of internal components.

[0169] In addition, by adjusting the shape and position of the protrusions (510a, b, c), it is possible to design a flow path capable of responding to various application environments, which has the advantage of facilitating integration with high-performance air conditioning systems or intake and exhaust circulation devices.

[0170]

[0171] In one embodiment, the case (500) may have a cutting blade (not shown in the drawing for convenience of explanation) disposed inside for cutting hair.

[0172] In the case (500), the drum (100) is positioned on the inside and is designed to accommodate various functional components as a structure constituting a head including a comb (220) and its driving part.

[0173] In this embodiment, a cutting blade capable of cutting hair in a manner similar to a hair clipper is placed inside the case (500).

[0174] This cutting blade can perform the function of cutting and removing hair that enters through the comb (220) while in contact with the user's skin or the area being processed.

[0175] The cutting blade can be synchronized with the rotation of the drum (100) or operated independently by a separate motor or drive mechanism, and can be fixedly installed at a certain position to match the entry and exit path of the comb.

[0176] The cutting blade may be formed of high-hardness metal or wear-resistant ceramic material, and considering that it is a structure that comes into contact with the skin, a safety guard or an anti-interference design may be included.

[0177] In addition, the cutting blade can be mounted in a structure that considers ease of maintenance so that it can be easily detached and replaced inside the case, and may include an adjustment mechanism that can adjust the length or sharpness of the cutting blade according to the user's usage environment.

[0178] The cutting function can be designed to operate in conjunction with the vibration or movement of the comb (220), and can also be linked with a trigger structure so that cutting occurs only when hair enters or reaches a specific location.

[0179] This configuration allows the rotating drum (100) to be applied directly to the user's skin during operation or to cut hair on the surface of the workpiece, thereby efficiently removing hair so that it does not get tangled inside the device or interfere with operation, thus improving the stability and functionality of the device.

[0180] A rotary drum having a comb that moves in and out according to one embodiment of the present invention having the configuration described above can perform combing or vibration functions simultaneously with hair removal by integrating a cutting blade for cutting hair inside the case (500), thereby realizing structural integration that enables complex grooming tasks to be performed without using a separate hair clipper or cutting device.

[0181]

[0182] In one embodiment, the case (500) is provided with a handle (520) so that the user can grasp it from above or the side, as shown in FIG. 4.

[0183] The case (500) is a structure in which a drum (600) is positioned inside to form a head, and is a structure that includes a comb drive unit or related module inside, and is designed to facilitate maintenance and movement of the device.

[0184] A rotary drum having a comb that moves in and out according to one embodiment of the present invention, having the configuration described above, is provided with a handle on the case (500) that a user can grasp from above or the side, thereby making movement and maintenance of the device easier and providing the effect of increasing practicality and safety in various work environments.

[0185]

[0186] In one embodiment, the drum (600) may be installed so as to be detachable inside the case (500).

[0187] The drum (600) is a rotating structure in which the movement of the comb (220) is performed, and in this embodiment, it is mounted inside the case (500), but is designed so that it can be easily detached and reattached depending on the user's work purpose or maintenance needs.

[0188] The detachable structure can be implemented through mechanical means such as, for example, a fixed bracket, a sliding rail, a snap fastening, or a rotating locking ring, and is configured to allow the drum (600) to be moved or rotated in a vertical or horizontal direction to be separated from inside the case (500).

[0189] This structure allows the drum (600) to be selectively separated for cleaning, inspection, or replacement without disassembling the entire device when contamination, wear, or damage occurs to the comb openings (140a, 140b) formed inside the drum (600) or to the inner driving mechanism, thereby shortening work time and improving maintenance efficiency.

[0190] In addition, the detachable structure allows the rotating or driving part of the drum (600) to be easily replaced even while the case (500) is maintained as a fixed structure, thereby providing a flexible system that enables multi-functional operation within the same case structure by replacing and mounting drum (600) modules having various shapes or purposes.

[0191] A rotary drum having a comb-like movement according to one embodiment of the present invention having the configuration described above provides the effect that the convenience of maintenance and replacement of the drum (600) module is improved by installing the drum (600) inside the case (500) so as to be detachable, and that structural conversion suitable for various work purposes is possible, thereby maximizing the flexibility of the system and industrial practicality.

[0192]

[0193] In one embodiment, the case (500) may have a comb cap (530) in an opening where the comb (920) is exposed, as shown in FIG. 4.

[0194] The case (500) is formed in a structure that encloses the interior of the drum (600) and includes an opening in an open structure corresponding to the area where the comb (920) moves in and out.

[0195] This opening is provided so that the comb (920) is exposed to the outside to perform tasks such as scraping, removing, and cleaning.

[0196] In these openings, a comb cap (530) is additionally provided to protect the comb (920) exposed to the outside and to prevent contact with the user or entry of foreign matter during operation.

[0197] The comb cap (530) can be formed from a flexible material or a high-strength transparent or opaque plastic, silicone, urethane, etc., and can be manufactured as an integral or separate part of the case (500).

[0198] The comb cap (530) can also perform the function of guiding the path of the comb (920) to enter and exit without completely blocking the opening, or limiting the range so that it protrudes only to a certain position.

[0199] The provision of such comb caps (530) contributes to safely operating the device in an external environment, and can simultaneously ensure the stability of the device and user safety, especially in environments where physical contact or foreign matter contamination is frequent.

[0200] A rotary drum having a comb that moves in and out according to one embodiment of the present invention, having a configuration as described above, is provided with a comb cap (530) in a comb exposure opening formed in a case (500), thereby safely protecting the exposed area of ​​the comb, preventing the ingress of foreign matter into the device or user accidents, and simultaneously improving the durability and reliability of the device.

[0201]

[0202] FIGS. 4 to 6 are drawings illustrating the schematic configuration of a rotating drum in which a comb moves in and out according to a second embodiment of the present invention.

[0203] Referring to FIGS. 4 to 6, a rotating drum (20) in which a comb moves in and out according to a second embodiment of the present invention includes a case (500), a drum (600), a first cam device (700a), a second cam device (700b), and a comb structure (900).

[0204] The case (500) is a main body exterior structure formed with a hollow interior and an opening facing forward, as shown in FIG. 4, and accommodates main driving components such as a drum (600) and a cam device (700a, 700b) inside. The case (500) may have an external handle formed so that a user can hold it with their hand, and the comb teeth are exposed to the outside through the front opening to be guided to come into contact with the object to be cleaned or the target. The case (500) must have sufficient internal space to maintain structural rigidity without interfering with the rotation of the internal rotating body or the reciprocating motion of the comb teeth, and may also have an intake port or a blower port formed therein.

[0205] The drum (600) is rotatably connected and installed inside the case (500), and a plurality of comb openings are formed along its outer surface. The drum (600) receives rotational force from the first cam device (700a) to the second cam device (700b) and performs rotational movement around a central axis, thereby inducing the combs on its outer surface to perform rotational and entry / exit movements together.

[0206] The first cam device (700a) is rotatably connected to one side of the case (500) and is positioned eccentrically on one side of the drum (600). The first cam device (700a) is configured to be gear-coupled with the drum (600) and thereby transmits rotational force to the drum. It consists of a cam shaft, a cam gear, and a cam, and induces an in-and-out movement by directly interacting with the teeth inside the drum.

[0207] The second cam device (700b) is rotatably connected to the other side of the case (500) in a structure facing the first cam device (700a) and is eccentrically positioned on the inner side of the other side of the drum (600). The second cam device (700b) is also gear-coupled with the drum (600) and performs synchronized rotation together with the first cam device (700a). Both cam devices are implemented in a symmetrical or synchronous structure to simultaneously transmit rotational force at both ends of the drum and to stably control the comb inside the drum.

[0208] Here, the first cam device (700a) and the second cam device (700b) are identical to the cam device (400) described above in FIG. 2, so a more detailed description is omitted to avoid duplication of explanation.

[0209] The comb structure (900) of FIG. 6 is rotatably connected to the first cam device (700a) and the second cam device (700b), respectively, and performs reciprocating motion, i.e., inward and outward motion, in the horizontal direction relative to the drum (600) as both cam devices (700a, 700b) rotate. The cam device (700) can be installed inside the gearbox (750), and when installed in this way, the cam shaft is stabilized so that the rotation of the cam is smoother, and if a bearing is placed in the gearbox (750), it can be rotated while minimizing friction with the drum. Both ends of the cam shaft comb structure (900) are installed so that they pass through the outer circumference of the drum (600) and are exposed to the outside, and repeat periodic advance and retraction in the left and right directions by the rotational motion of the cam devices (700a, 700b). Thus, the comb structure (900) can effectively scrape off foreign matter between the cleaning material or hairs, and, in conjunction with the rotation of the drum, transport the foreign matter to a specific location or guide it to a suction zone.

[0210] A rotary drum (20) having a comb moving in and out according to the second embodiment of the present invention having the configuration described above can implement a multi-cam-based active rotary drum structure that can automatically remove foreign matter even during continuous brushing operations and stably perform brushing and cleaning over a wider range by rotating the drum through two cam devices installed in the case and performing a horizontal movement of combs connected to both ends synchronized with this rotation.

[0211]

[0212] Referring to FIG. 6, the comb structure (900) includes a support shaft (910), a plurality of first combs (920a), and a plurality of second combs (920b).

[0213] The support shaft (910) is positioned along the inner side of the drum (600) and is configured to be connected so that one end and the other end are eccentrically connected to the center of the first cam device (700a) and the second cam device (700b), respectively, so as to be rotatable. The support shaft (910) performs reciprocating motion in the horizontal direction inside the drum (600) in conjunction with the rotational motion of the cam devices (700a, 700b). The support shaft (910) is formed of a metal or composite material with excellent rigidity to withstand repetitive vibrations and shocks, and is designed so that both ends are rotatably connected to the cam or comb joint of the cam devices (700a, 700b) to induce precise movement.

[0214] A plurality of first comb teeth (920a) are spaced apart at regular intervals along the front of the support shaft (910). Each first comb tooth (920a) is positioned to be exposed to the outside by passing through a plurality of first comb tooth openings (not shown in the drawing for convenience of explanation) formed on the outer circumference of the drum (600). When the support shaft (910) reciprocates in the horizontal direction, the first comb teeth (920a) repeatedly protrude outward or are retracted inward through the first comb tooth openings, performing the function of scraping the surface of the object to be cleaned or grooming the hair. Each comb tooth is formed from a plastic or metal material, and its ends are processed to be smooth or curved so as not to damage the skin or fibers.

[0215] Multiple second combs (920b) are installed at regular intervals along the rear of the support shaft (910), just like the first combs (920a). The second combs (920b) are positioned so as to be exposed to the outside through multiple second comb openings (not shown in the drawing for convenience of explanation) formed on the outer circumference of the drum (600), and likewise perform repeated movement in and out according to the reciprocating motion of the support shaft (910). The second combs (920b) are paired with the first combs (920a) and contribute to enhancing the performance of removing foreign matter in both directions overall, and maximizing the combing and suction effects.

[0216] The first comb (920a) and the second comb (920b), respectively positioned at the front and rear of the support shaft (910), operate as a single unit synchronized with the rotation of both cam devices (700, 800) and perform the function of effectively pulling out or moving foreign matter along with the rotation of the drum (600) by repeating incoming and outgoing movements in opposite or same directions.

[0217] A comb structure (900) according to one embodiment of the present invention having the configuration described above performs a reciprocating motion in a horizontal direction along the inner side of a drum centered on a support shaft (910) with both ends eccentrically connected, and a first comb (920a) and a second comb (920b) linked thereto repeatedly enter and exit through the entrances (610, 620) on the outer circumference of the drum, thereby effectively removing hair or foreign matter caught on the surface to be cleaned, and in particular, by adopting a comb structure on both sides, it is possible to simultaneously achieve an expansion of the work area and a maximization of cleanliness maintenance performance.

[0218]

[0219] FIGS. 7 to 10 are drawings showing the configuration of a rotating drum in which a comb moves in and out according to a third embodiment of the present invention.

[0220] Referring to FIGS. 7 to 10, a rotating drum (30) in which a comb moves in and out according to one embodiment of the present invention includes an eccentrically arranged pusher (1300) and a comb elastic body (1430).

[0221] The pusher (1300) is eccentrically positioned on the inner side of the drum (1000) at a predetermined distance from the rotational center axis of the drum (1000).

[0222] This pusher (1300) performs rotational movement on the inside in synchronization with the rotation when the drum (1000) rotates, and can perform the action of pushing or pulling the comb (1420) along the inner surface of the drum (1000) during rotation.

[0223] In particular, the pusher (1300) is designed to control the timing of the entry and exit of the comb by applying thrust that pushes the comb (1420) outward in a specific section in conjunction with the rotational trajectory of the drum (1000).

[0224] The comb (1420) is positioned inside the comb opening of the drum (1000) and is guided to protrude outward or be inserted inward.

[0225] This comb (1420) performs an in-and-out movement according to the rotation of the drum (1000) and the action of the pusher (1300).

[0226] In particular, the comb (1420) is configured to be combined with or placed on the comb elastic body (1430) to prevent damage from external impact or friction and to relieve fatigue from repeated operation.

[0227] The comb elastic body (1430) is positioned to support the comb (1420) inside the comb opening and provides an elastic restoring force that automatically returns the comb to its original position when there is no pushing action by the pusher (1300).

[0228] These comb elastic bodies (1430) can be implemented using various restoring means such as coil springs, elastic rubber, or memory shape alloys, and can perform the function of stably maintaining the position of the comb even against vibrations or excessive shocks that occur during rotation.

[0229] A rotating drum (30) having a configuration as described above, according to one embodiment of the present invention, which allows a comb to move in and out, provides the effect of realizing a structure in which the comb (1420) can move in and out naturally and periodically by rotation alone without external power through the interaction between a pusher (1300) eccentrically disposed inside the drum (1000) and a comb elastic body (1430) disposed at the comb entrance.

[0230] In addition, the return structure using the comb elastic body (1430) enables automatic return of the comb without a separate driving mechanism, thereby providing advantages that contribute to the simplification of the device, ease of maintenance, and improved durability.

[0231]

[0232] In one embodiment, the comb (1420) may be configured in multiple rows along the longitudinal direction of the drum (1000) as shown in FIG. 8.

[0233] The comb (1420) has a structure that is arranged at regular intervals along the outer surface of the drum (1000).

[0234] In particular, in this embodiment, the drum (1000) is configured with a plurality of rows along the axial direction, that is, the length direction, so as to be designed to widely cover the overall operating area of ​​the drum (1000).

[0235] This multi-row structure provides a configuration that can significantly improve work efficiency compared to a single-row array.

[0236] The combs (1420) arranged in each row periodically move in and out with the rotation of the drum (1000) as described in claim 1, and are exposed to the outside or inserted into the inside through an opening formed on the outer surface of the drum (1000) depending on the angle of rotation.

[0237] Multiple comb rows can operate independently without interference with each other, or, if necessary, can operate synchronously through the same cam device (400) or drive shaft.

[0238] This arrangement can be particularly advantageous for processing long objects or materials that are widely distributed along the length of the drum (1000), and by increasing the area through which the comb enters and exits, more precise and uniform scraping, cleaning, and conveying operations can be performed.

[0239] A rotating drum (30) having a comb-like movement according to one embodiment of the present invention having the configuration described above has a plurality of rows of combs (1420) configured along the length direction of the drum (1000), thereby enabling comb operation over a wider range and providing substantial effects such as expanding the working area of ​​the device and improving processing efficiency.

[0240] In addition, the multi-row structure has the advantageous ability to flexibly respond to various process environments by adjusting the rotation range and operating range of the drum (1000).

[0241]

[0242] The rotating drum (10, 20, 30) in which the comb moves in and out according to the first, second, and third embodiments of the present invention having the configuration described above can be designed to be applied to various types of devices or equipment based on its structural characteristics and the flexibility of its operation mechanism.

[0243] In particular, the rotary drum of the present invention can be configured to be suitable for a complex operating device requiring a combing function and a hair removal or grooming function simultaneously, and accordingly, the following application examples are possible.

[0244] First, it is installed in the internal drive unit of a hair cutting device, such as a hair clipper or electric trimmer, and can perform the function of tidying hair while simultaneously precisely cutting it with a cutting blade as the comb moves in and out along with the rotation of the drum.

[0245] Second, it can be applied to a beauty device that includes a roller brush or roller comb, and can prevent hair tangling through periodic vibration or movement of the comb teeth, and provide the function of stimulating or massaging the user's scalp.

[0246] Third, it can be utilized as a functional component embedded inside a vacuum cleaner or a vacuum cleaner head for removing fine dust, which organizes and cuts foreign substances such as fibers or hair to improve suction efficiency.

[0247] Fourth, it can be mounted inside or outside a hair dryer that includes a drying function, and as the rotating drum is driven with the wind, it can perform an auxiliary function of styling hair and effectively removing hair or dust.

[0248] As such, the rotary drum of the present invention can be applied in various ways as an auxiliary module or core drive unit to improve the functionality and convenience of existing devices, and the rotational speed of the drum, the timing of the entry and exit of the comb, and the operating conditions of the cutting blade can be optimized to suit the structure and use of each device.

[0249] Accordingly, the rotary drum of the present invention, in which the comb teeth move in and out, provides high versatility and compatibility that allow it to be practically utilized as an internal component of various electronic or beauty devices, such as hair clippers, roller combs, vacuum cleaner heads, and hair dryers, thereby enabling the realization of a high-functional device that satisfies the diverse needs of users.

[0250]

[0251] Figures 7 to 9 are drawings showing a comb composite.

[0252] Referring to FIGS. 7 to 9, the comb composite (1400-1 to 1400-4) includes a comb (1420) installed in a comb holder (1410), a comb elastic body (1430), a fixing jaw (1440), and a body part (1460).

[0253] The comb holder (1410) is formed hollowly on the inner side of the drum (1000) and provides space for the body part (1460) to move up and down inside. Multiple comb holders (1410) are arranged along the inner side of the drum (1000), and each holder serves as a housing for an individual operating unit in which the comb can be advanced or stored.

[0254] The body portion (1460) is positioned to be vertically movable inside the comb holder (1410), and its lower end is exposed toward the internal space of the drum (1000). When the drum (1000) rotates, the lower end of the body portion (1460) is sequentially pushed by the internal eccentric pusher (1300) and moves upward. The body portion (1460) is formed with a straight or curved structure of a certain cross-section, and is configured to protrude the comb outward when rising and return to its original position by the restoring force of the elastic body when returning.

[0255] The comb elastic body (1430) is a spring or elastic member installed between the upper part of the body portion (1460) and the upper side of the comb holder (1410), and operates to naturally move downward again as the drum (1000) rotates after the body portion (1460) moves upward. This elastic body (1430) affects the rotation speed of the drum (1000) and the return speed of the comb, and serves to structurally prevent strain even if foreign matter gets stuck or resistance occurs.

[0256] The fixing jaws (1440) are formed on both upper sides of the body portion (1460) and prevent the body portion from rising excessively and detaching from the comb holder (1410). The fixing jaws are formed with a protruding or undercut structure of a certain size, serving as a physical restraint to prevent the body portion (1460) from coming off completely, and ensuring structural stability even during long-term use.

[0257] In one embodiment, the fixing jaw (1440) can guide the linear movement of the comb (1420) by guiding the entry and exit path of the comb (1420) while moving linearly along the comb holder (1410).

[0258] The fixing jaw (1440) is formed on both upper sides of the body portion (1460) and acts as a safety structure to prevent the body portion (1460) from rising excessively and detaching when moving up and down along the comb holder (1410). The fixing jaw (1440) is formed with a protruding or undercut shape of a certain size, thereby restricting the body portion (1460) to maintain stable linear movement within the comb holder (1410) and ensuring structural durability even during long-term repetitive operation. Additionally, the fixing jaw (1440) performs a function similar to a guide rail that guides a straight path along the inner wall of the comb holder (1410), thereby ensuring alignment so that eccentricity or twisting does not occur when the comb (1420) protrudes outward or is stored inward through the comb entrance (1450).

[0259] Due to the provision of such a fixed jaw (1440), the comb (1420) can always perform an in-and-out movement along a constant straight path, and as a result, the ends of the comb act stably at a constant position during combing or cleaning. This prevents the comb (1420) from tilting or bending abnormally, thereby ensuring uniformity in combing performance and maintaining constant contact pressure on the object to be cleaned. Furthermore, the fixed jaw (1440) fundamentally prevents the body part (1460) from detaching during repeated operation, thus extending the lifespan of the device and reducing the frequency of maintenance. Additionally, even if foreign matter enters the usage environment, the fixed jaw (1440) controls the path of the body part (1460), thereby minimizing friction or jamming and enabling smooth and continuous operation.

[0260] In other words, it can be summarized that the fixed jaw (1440) functions as a key component that goes beyond a simple anti-detachment structure, stably guides the linear movement of the comb (1420), and ensures the durability and reliability of the entire device.

[0261] The above fixed jaw (1440) is merely an example, and the shape of the fixed jaw can be manufactured in various ways to perform such a function.

[0262] The comb opening (1450) is an opening formed to communicate from the outer surface of the drum (1000) to the comb holder (1410), and serves as a passage through which the comb (1420) located on the upper side can protrude outward when the body part (1460) moves upward. This opening is formed in a conventional circular or elliptical shape and functions as a path through which the comb can come into contact with the outside during the foreign matter suction or removal operation.

[0263] The comb (1420) is fixedly installed on the upper side of the body part (1460) and protrudes out of the drum or is retracted into the drum through the comb opening (1450) as the body part moves up and down. The comb is formed with multiple bristles or thin protrusions and performs functions such as scraping off foreign matter from the object to be cleaned or tidying up hair. The material may be made of synthetic resin, fiber, metal, etc., which have excellent elasticity and resilience, and is designed so as not to wear out easily even with repeated entry and exit movements.

[0264] A rotary drum (10) according to one embodiment of the present invention having the configuration described above provides an automatic entry / exit mechanism in which, as the drum (1000) rotates, an eccentric pusher (1300) raises the body portion (1460) to protrude the comb (1420) outward and allows it to return naturally by means of an elastic body (1430), thereby enabling a user to perform continuous and efficient removal of foreign matter, cleaning, or grooming without separate operation, and simultaneously secure structural integrity of the drum internal space and operational reliability of the comb.

[0265]

[0266] Referring to FIGS. 7 to 10, the rotary drum (10) includes a drum (1000), a cover (1100-1, 1100-2), a drum drive unit (not shown in the drawings for convenience of explanation), a pusher (1300), and a comb composite (1400-1 to 1400-4).

[0267] The drum (1000) is a cylindrical structure with a hollow interior and is designed to rotate around a rotation axis. A plurality of comb-shaped openings are formed on the outer surface of the drum (1000), and a comb-shaped composite (1400-1 to 1400-4) is housed inside and performs an inward and outward movement as it moves outward or inward as it rotates.

[0268] The covers (1100-1, 1100-2) are structures that cover both sides of the drum (1000) and form a space for the rotation of the drum (1000) while simultaneously performing the function of protecting and supporting the internal components. The covers (1100-1, 1100-2) are each connected to both ends of the drum (1000) to support the fixation of the rotation axis and the pusher, and can also implement a sealed structure that prevents external dust or contamination from entering the interior.

[0269] The drum drive unit is a component that mechanically connects the motor and the drum (1000) and performs the function of rotating the drum (1000) by directly transmitting the rotational force of the drive motor to the drum (1000). The drum drive unit may be composed of drive transmission elements such as gears, belts, couplings, or shafts, and a reduction gear or torque controller may be added to increase drive stability.

[0270] The pusher (1300) is configured to penetrate the internal space of the drum (1000) in the longitudinal direction, and both ends thereof are rotatably supported by the cover (1100-1, 1100-2). The pusher (1300) is eccentrically positioned at a predetermined distance from the rotation centerline of the drum (1000), and pushes or pulls the comb composite (1400-1 to 1400-4) as its relative position inside changes whenever the drum (1000) rotates.

[0271] The comb components (1400-1 to 1400-4) are arranged in the internal space of the drum (1000) and are elements that perform an in-and-out movement by being pushed or pulled by the pusher (1300) along with the rotation of the drum. Multiple comb components (1400-1 to 1400-4) are arranged at regular intervals along the longitudinal direction of the drum (1000), and as the drum (1000) rotates, the point of action of the pusher (1300) comes into contact with these structures in turn. As a result, each comb component (1400-1 to 1400-4) sequentially moves out of the drum one by one and then repeats the action of being retracted back inside after a certain rotation. Through this, the comb performs a periodic in-and-out movement while the drum (1000) rotates, and as a result, the removal of foreign matter and hair grooming can be performed in an automated manner.

[0272] The rotating drum (30) in which the comb moves in and out according to the third embodiment of the present invention having the configuration described above can induce a movement of pushing or pulling the comb composite (1400-1 to 1400-4) periodically during rotational movement by eccentrically arranging the pusher (1300) so as to be spaced apart from the center of the drum (1000), and thereby can provide an automatic cleaning mechanism in which the comb that effectively contacts the combing target automatically separates foreign matter and is stored again.
