[0055] Please refer to Figures 1 to 11 The present application provides a pet feeder, which is mainly used for realizing the purpose of providing food for pets in a timed and quantitative manner. In order to facilitate understanding, in the following embodiments, the pet feeder is taken as an example to be described, which has an up-down direction and a horizontal direction arranged in a substantially cross manner. The up-down direction is substantially the same as the direction of gravity, and the horizontal direction is any direction on the horizontal plane.

[0056] Specifically, the pet feeder includes but is not limited to a main cylinder 100, a top cover 200, a food bin 300, a dish 400, a food outlet passage 500 and a feeding device.

[0057] The main cylinder 100 is formed with a receiving cavity with an open upper end; the top cover 200 is arranged at the opening of the main cylinder 100. The food bin 300 is used to store foodstuff, and is received in the receiving cavity and can be detached from the opening. The lower bottom of the food bin 300 is provided with a discharge port. The dining plate 400 is arranged below the food bin 300. The food outlet passage 500 is located between the food bin 300 and the dining plate 400. The food outlet passage 500 has an upper inlet and a lower outlet, and the lower outlet faces the dining plate 400.

[0058] The feeding device comprises a clutchable impeller assembly 600 and a driving assembly 700. The impeller assembly 600 is arranged at the bottom of the food bin 300 and can be synchronously detached with the food bin 300. The impeller assembly 600 comprises a rotating impeller sleeve 610, an elastic member 620 and a movable plug 630. The movable plug 630 is movably arranged in the interior of the impeller sleeve 610 and can drive the impeller sleeve 610 to synchronously rotate. The elastic member 620 is arranged on the movable plug 630. The driving assembly 700 is fixedly arranged below the impeller assembly 600. The driving assembly 700 comprises a power source 710 and a convex shaft 720 connected with each other.

[0059] One of the connection positions of the movable plug 630 and the convex shaft 720 is provided with a slot 631, and the other is provided with a plug 721. After the food bin 300 is installed in place in the receiving cavity, the plug 721 is coaxially arranged with the slot 631 and is rotationally plugged.

[0060] In the technical scheme, when the food bin 300 needs to be detached from the receiving cavity, the impeller assembly 600 and the driving assembly 700 are synchronously separated.

[0061] When the food bin 300 needs to be installed in the receiving cavity, the impeller assembly 600 is synchronously driven to approach the driving assembly 700. The approaching direction of the two is the plugging direction of the slot 631 and the plug 721, so that the slot 631 and the plug 721 are pluggably connected with each other. In this process, even if the slot 631 and the plug 721 are not completely plugged in place, the elastic member 620 will be deformed under the plugging force between the movable plug 630 and the convex shaft 720, so as to drive the movable plug 630 to retract into the interior of the impeller sleeve 610, thereby reserving sufficient avoiding space for the food bin 300 to be smoothly received in the receiving cavity. Then, in the process of rotating the convex shaft 720 driven by the power source 710, the plug 721 and the slot 631 can be adjusted in position, so as to ensure that the plug 721 and the slot 631 can be finally plugged in place.

[0062] After the slot 631 and the block 721 are inserted into the position, the slot 631 and the block 721 are coaxial and rotationally fixed, which helps to simultaneously insert the driving assembly 700 and the impeller assembly 600 into the position, without the need for additional adjustment or review of the alignment between the driving assembly 700 and the impeller assembly 600, and helps to reduce the loss of power transmitted from the driving assembly 700 to the impeller assembly 600, and ultimately improves the use quality of the pet feeder, thereby improving the user experience.

[0063] Specifically, the main cylinder 100 extends substantially in the up-down direction, and the horizontal cross-sectional shape thereof can be, but is not limited to, a circle, an ellipse, a polygon, or any suitable special shape, etc.

[0064] As shown in Figures 1 to 4 The main cylinder 100 defines an accommodation cavity inside, the upper end of the accommodation cavity is open, and the side wall of the accommodation cavity is provided with an opening in the lower region. The top cover 200 is movably mounted at the opening to be able to open and close the accommodation cavity.

[0065] The dinner plate 400 is located outside the main cylinder 100 and is disposed below the opening.

[0066] A section of the food outlet channel 500 is accommodated in the accommodation cavity, another section extends outward through the opening and extends towards the dinner plate 400. The food outlet channel 500 can be inclined and extended according to actual needs. The lower end outlet of the food outlet channel 500 is located above the dinner plate 400.

[0067] Since the food bin 300 and the feeding device are both accommodated in the accommodation cavity, in order to ensure the stable assembly of the food bin 300 and the feeding device, specifically, one or at least two shell plate structures can be provided in the accommodation cavity to support the food bin 300 and / or the feeding device. For example, one or at least two first shell plates are provided to separate the accommodation cavity into an upper chamber and a lower chamber. The food bin 300 and the impeller assembly 600 are supported at the first shell plate of the upper chamber. At this time, the shape of the first shell plate is configured to be adapted to the partial outer wall of the food bin 300 and / or the partial outer wall of the impeller assembly 600, so as to realize the stable placement of the food bin 300 and the impeller assembly 600 at the first shell plate. The driving assembly 700 is accommodated in the lower chamber, and the impeller assembly 600 and / or the driving assembly 700 penetrate through the first shell plate and are connected.

[0068] The food bin 300 defines a storage cavity inside. The storage cavity can store food. The bottom of the food bin 300 is provided with a discharge port. The food stored in the storage cavity can be discharged downward through the discharge port.

[0069] In order to avoid the foodstuff from being accumulated or adhered on the bottom of the storage cavity, in a further aspect, the pet feeding device further comprises a movable stirring member 640. The movable stirring member 640 is movable relative to the bottom of the storage cavity, so that during its movement, a disturbance is generated in the storage cavity, especially near the bottom of the storage cavity, to drive the foodstuff to move and avoid local accumulation or adhesion.

[0070] The movable stirring member 640 can be movable in a rotating and / or translational manner. The specific structure of the movable stirring member 640 is suitably set according to its movement manner.

[0071] The movable stirring member 640 described above needs a driving source to drive it. According to actual needs, the driving source can be a power mechanism independently arranged and dedicated to driving the movable stirring member 640. Alternatively, the driving source can be constituted by other power mechanisms fixed in the pet feeding device, for example, by the driving assembly 700 described above.

[0072] Of course, the impeller assembly 600 in the feeding device can be built-in in the storage cavity. In this case, the impeller assembly 600 can be reused to constitute the movable stirring member 640 described above.

[0073] Alternatively, the impeller assembly 600 can be externally arranged in the food bin 300. In particular, the impeller assembly 600 can be arranged at the bottom of the food bin 300. The impeller assembly 600 and the food bin 300 are generally detachably connected.

[0074] In order to improve the connection strength in the connected and fixed state, in a further aspect, the pet feeding device further comprises a bottom shell 810, which is arranged on the bottom of the food bin 300 and encloses an installation cavity with the bottom of the food bin 300. The impeller assembly 600 is movably arranged in the installation cavity. The bottom shell 810 is provided with a feeding opening 811, which is located directly above the upper end inlet of the feeding passage 500.

[0075] The feeding opening 811 of the bottom shell 810 and the discharging opening of the food bin 300 can be arranged in sequence along the vertical direction. Alternatively, the feeding opening 811 of the bottom shell 810 and the discharging opening of the food bin 300 are arranged in a staggered manner along the horizontal direction.

[0076] The impeller sleeve 610 in the impeller assembly 600 can be constituted by a single impeller structure, or can be jointly constituted by at least two impeller structures.

[0077] Generally, the impeller set 610 as a whole comprises a protruding portion 611 and blades 612 protruding radially from the outer wall of the protruding portion 611. The blades 612 are arranged in at least two along the circumferential direction of the protruding portion 611. Each two adjacent blades 612 define a dosing storage space 613 for receiving foodstuff falling downward from the discharge port. The central axis of the protruding portion 611 extends along the vertical direction and corresponds to the rotation axis of the impeller set 610 as a whole. The dosing storage space 613 extends through the blades 612 along the axial direction of the impeller set 610 and radially outward.

[0078] When the impeller set 600 is installed in the installation cavity, the bottom cover 810 can seal the radially outer side of the dosing storage space 613. At this time, when the impeller set 610 rotates and drives the dosing storage space 613 to rotate to the lower side of the discharge port, the foodstuff falling outward through the discharge port can be received. When the impeller set 610 rotates and drives the dosing storage space 613 to rotate to the discharge port 811, the lower end of the dosing storage space 613 is open, and the foodstuff stored in the dosing storage space 613 can fall downward to the food outlet passage 500.

[0079] Then, the pet feeder further comprises a fixed pusher 820. One end of the fixed pusher 820 can be fixedly installed to the bottom of the food bin 300 or the side wall of the bottom cover 810. The other end of the fixed pusher 820 extends towards the blades 612 and is close to the blades 612, so that when the foodstuff falling outward through the discharge port falls on the blades 612, the foodstuff can be pushed by the fixed pusher 820 into the dosing storage space 613 during the relative displacement between the impeller set 610 and the fixed pusher 820.

[0080] When the movable pusher 640 is arranged as described above, in a specific embodiment, the bottom of the food bin 300 can be provided with an installation hole. The protruding portion 611 of the impeller set 610 extends into the storage cavity through the installation hole and is rotationally connected with the movable pusher 640. In this way, on the one hand, the movable pusher 640 can be rotated synchronously by the rotation of the impeller set 610. On the other hand, the impeller set 610 can be limited by the movable pusher 640. The impeller set 610 is suspended below the movable pusher 640 and can maintain that the impeller set 610 does not contact the outer bottom of the food bin 300 or the inner bottom of the bottom cover 810 as much as possible during the rotation of the impeller set 610.

[0081] The elastic member 620 and the movable plug 630 are arranged in the impeller set 610. Specifically, as shown in FIG. 6, the elastic member 620 is arranged in the protruding portion 611 of the impeller set 610 and is connected with the movable plug 630. Figures 3 to 6In the shown embodiment, when the impeller sleeve 610 comprises the protrusion 611 and the blade 612 as described above, the lower end of the protrusion 611 is recessed with a receiving groove 614. The groove mouth of the receiving groove 614 faces downward. The movable plug 630 and the elastic member 620 are both arranged in the receiving groove 614, and the movable plug 630 is elastically movable along the depth direction (generally the upward and downward direction) of the receiving groove 614. In this way, the movable plug 630 has the floating freedom along the upward and downward direction during the docking process of the impeller assembly 600 and the driving assembly 700, so as to ensure that the movable plug 630 and the protruding shaft 720 first elastically abut. Until the plug block 721 is inserted into the plug groove 631 during the abutting process, the accurate docking is completed.

[0082] The specific form of the elastic member 620 is not limited, which can be but is not limited to a spring member, a rubber block, a metal spring piece, etc. According to the different specific forms of the elastic member 620, different assembly modes can be matched between the impeller sleeve 610, the elastic member 620 and the movable plug 630.

[0083] The elastic member 620 can be arranged between the inner side wall of the receiving groove 614 and the outer side wall of the movable plug 630, and / or arranged outside the receiving groove 614. In order to avoid the arrangement of the elastic member 620 interfering with the docking of the impeller assembly 600 and the driving assembly 700, specifically, as shown, the receiving groove 614 comprises a first groove section 614a and a second groove section 614b connected in sequence from bottom to top. The inner diameter of the first groove section 614a is greater than that of the second groove section 614b, so as to form a first stop surface 614c facing downward at the connection between the two. Figures 3 to 6

[0084] The movable plug 630 comprises a first plug section 630a and a second plug section 630b connected in sequence from bottom to top. The outer diameter of the first plug section 630a is greater than that of the second plug section 630b, so as to form a second stop surface 630c facing upward at the connection between the two.

[0085] The elastic member 620 is arranged at the position of the movable plug 630 away from the protruding shaft 720. More specifically, the elastic member 620 can be arranged in a cylindrical structure such as a spring member. The elastic member 620 is sleeved on the periphery of the second plug section 630b. The elastic member 620 can be limited between the first stop surface 614c and the second stop surface 630c.

[0086] Further, the outer diameter of the first plug section 630a is matched with the inner diameter of the first groove section 614a. In this way, the outer wall of the first plug section 630a and the inner groove wall of the first groove section 614a are equivalent to sliding abutment. And enough space can be reserved between the first groove section 614a and the second plug section 630b for the arrangement of the elastic member 620. ​

[0087] The outer diameter of at least the upper section of the second plug-in section 630b is adapted to the inner diameter of the second groove section 614b. After the food bin 300 is installed in place in the receiving cavity, at least the upper section of the second plug-in section 630b extends into the second groove section 614b. In this way, the outer wall of the second plug-in section 630b and the inner groove wall of the second groove section 614b are in sliding abutment.

[0088] When the movable plug-in member 630 moves relative to the impeller cover 610 along the axis, the sliding connection between the first plug-in section 630a and the first groove section 614a and the sliding connection between the second plug-in section 630b and the second groove section 614b can serve as a guide for the movement.

[0089] In an embodiment, one of the inner wall of the receiving groove 614 and the outer wall of the movable plug-in member 630 is provided with a guide rib 615, and the other is provided with a guide groove 632. The guide rib 615 and / or the guide groove 632 extend along the up-down direction. The guide rib 615 and the guide groove 632 are in sliding connection during the elastic movement of the movable plug-in member 630 relative to the impeller cover 610.

[0090] As shown in detail in Figures 9 to 11 The guide rib 615 is provided on the inner side wall of the first groove section 614a, and the guide groove 632 is provided on the outer wall of the first plug-in section 630a. There are four guide ribs 615 and guide grooves 632.

[0091] In an embodiment, one of the inner wall of the receiving groove 614 and the outer wall of the movable plug-in member 630 is provided with a buckle groove 616, and the other is provided with a buckle 633. The size of the buckle groove 616 along the up-down direction is greater than the size of the buckle 633 along the up-down direction. The buckle 633 extends into the buckle groove 616 and can be in mutual buckling with at least the lower groove wall of the buckle groove 616.

[0092] As shown in detail in Figures 9 to 11 The buckle 633 can be provided on the outer wall of the first plug-in section 630a, and the buckle groove 616 can be provided on the inner side wall of the first groove section 614a. When the guide rib 615 and the guide groove 632 are provided as described above, the buckle 633 / buckle groove 616 can be provided between two adjacent guide ribs 615 / guide grooves 632. The size of the buckle groove 616 along the up-down direction is greater than the size of the buckle 633, which ensures that the provision of the buckle 633 and the buckle groove 616 does not affect the movement of the movable plug-in member 630 relative to the impeller cover 610.

[0093] The lateral protrusion 611 of the buckle 633 includes a flat section at the lower end and an inclined section at the upper end. When the movable insert 630 moves to the lowermost limit position relative to the impeller cover 610, the flat section of the buckle 633 abuts against the lower end side groove wall of the buckle groove 616, limiting the movable insert 630 from being pulled out of the receiving groove 614.

[0094] The dimension of the buckle groove 616 in the up-down direction can be set to be not less than the maximum moving stroke of the movable insert 630 relative to the impeller cover 610, so that the buckle 633 remains inserted into the buckle groove 616 throughout the movement of the movable insert 630 relative to the impeller cover 610.

[0095] Alternatively, the dimension of the buckle groove 616 in the up-down direction can also be set to be less than the maximum moving stroke of the movable insert 630 relative to the impeller cover 610. At this time, when the movable insert 630 moves upward relative to the impeller cover 610, the inclined section of the buckle 633 abuts against the upper end side groove wall of the buckle groove 616, and the inclined section guides the buckle 633 to be pulled out of the buckle groove 616, without hindering the continuous movement of the movable insert 630 relative to the impeller cover 610.

[0096] Please refer to Figures 7 to 8 The driving assembly 700 includes a power source 710 and a convex shaft 720. The power source 710 can be directly formed by a driver such as a motor, or the power source 710 can be formed by a combination of a driver and a transmission device. The power source 710 has a power output shaft that rotates about an axis extending in the up-down direction.

[0097] The convex shaft 720 is connected to the power output shaft through a coupling, or as shown in the structure of Figures 7 to 8 The driving assembly 700 further includes a rotating member 730 and a grating sensor 740. The rotating member 730 is generally disc-shaped. The rotating member 730, the power output shaft, and the convex shaft 720 are coaxially connected, so that the rotating member 730, the convex shaft 720, and the impeller assembly 600 rotate synchronously under the driving of the power output shaft.

[0098] The rotating member 730 is provided with detection notches 731 spaced apart in the circumferential direction thereof. During rotation, the grating sensor 740 can confirm the rotation state of the rotating member 730, the convex shaft 720, and the impeller cover 610, such as the number of rotations, by sensing the detection notches 731.

[0099] Further, the above-mentioned parameters, such as the number of the quantitative storage spaces 613, the arrangement scheme of the quantitative storage spaces 613 relative to the impeller sleeve 610, the number of the detection gaps 731, and the arrangement scheme of the detection gaps 731 relative to the rotating member 730, can be set one by one, so that when the grating sensor 740 senses a certain detection gap 731, the corresponding quantitative storage space 613 can be moved to a certain target position, for example, directly below the discharge port or directly above the discharge port 811.

[0100] In view of the above one or more embodiments, it can be understood that the lower end of the movable plug-in part 630 can be provided with the above-mentioned plug 721. The upper end of the protruding shaft 720 can be provided with the above-mentioned slot 631. At this time, the slot opening of the slot 631 is arranged upward, which is easy to accumulate dirt during the long-term use of the pet feeder, resulting in unstable plug-in of the slot 631 and the plug 721. Therefore, in a further scheme, the lower end of the movable plug-in part 630 is preferably provided with the slot 631. The upper end of the protruding shaft 720 forms the plug 721.

[0101] In order to make the driving assembly 700 better transmit power to the impeller assembly 600, the slot 631 and the plug 721 in the above-mentioned need to be coaxially and rotationally connected. That is, in the connected state, the rotation axes of the slot 631, the movable plug-in part 630, the impeller sleeve 610, and the protruding shaft 720 are all collinear. And the movable plug-in part 630 and the protruding shaft 720 do not produce relative torsion.

[0102] There are various schemes to achieve the above-mentioned purpose, for example, for rotationally connected fitting, it can be achieved by additionally setting a key. Or as in the present scheme, the horizontal cross-sectional shape of the slot 631 and the plug 721 is non-circular. When the horizontal cross-sectional shape of the slot 631 and the plug 721 is non-circular, at least one rotation stop protrusion and rotation stop recess can be formed at the plug-in part of the slot 631 and the plug 721, the rotation stop protrusion and the rotation stop recess cooperate, which is enough to limit the relative torsion of the slot 631 and the plug 721.

[0103] The non-circular scheme has various forms, such as elliptical, polygonal, or others.

[0104] Specifically, when the above-mentioned quantitative storage spaces 613 are arranged at least two equidistantly along the circumference of the impeller sleeve 610; the horizontal cross-sectional shape of the slot 631 and the plug 721 is a polygon that is adapted, and the number of the polygon and the quantitative storage spaces 613 is the same, both are X. The polygon includes at least two identical sides, and the included angle between the two identical sides is the same as the included angle between each two adjacent quantitative storage spaces 613, both are S.

[0105] Specifically, when the horizontal cross-sectional shape of the slot 631 and the plug 721 is a polygon that is adapted to each other, for the convenience of understanding, the same side of the slot 631 is defined as the first side slot wall and the second side slot wall. The same side of the plug 721 is defined as the first outer side wall and the second outer side wall. Then when the driving assembly 700 drives the convex shaft 720 to rotate S degrees in the positive direction, the first side slot wall and the first outer side wall can be matched and fitted, the second side slot wall and the second outer side wall can be matched and fitted, and the slot 631 and the plug 721 can be inserted and connected. Conversely, when the driving assembly 700 drives the convex shaft 720 to rotate S degrees in the reverse direction, the first side slot wall and the second outer side wall can be matched and fitted, the second side slot wall and the first outer side wall can be matched and fitted, and the slot 631 and the plug 721 can also be inserted and connected. In this way, it is more helpful for the quick alignment of the slot 631 and the plug 721.

[0106] Specifically, when the quantitative storage space 613 is provided with two, and the two quantitative storage spaces 613 are arranged on the two radial sides of the impeller sleeve 610, the above-mentioned X is 2, and S is 180°. The horizontal cross-sectional shape of the slot 631 and the plug 721 is a center-symmetrical figure that is adapted to each other.

[0107] The center-symmetrical figure is that when the figure is rotated by 180°, it can still coincide with the figure at 0°. The center-symmetrical figure can be a rectangle, which has two groups of the same side. Or the rectangle can also be a square, and the two opposite sides constitute the same side. At this time, when the driving assembly 700 drives the convex shaft 720 to rotate 180° in the positive direction or in the reverse direction, the accurate butt joint of the slot 631 and the plug 721 can be realized. When the food bin 300 is successfully placed in the accommodation cavity, but the slot 631 and the plug 721 are not completely aligned, through the above-mentioned arrangement, it is helpful to match the accurate insertion position between the slot 631 and the plug 721 after the power source 710 drives the convex shaft 720 to rotate as small an angle as possible, so that the insertion of the slot 631 and the plug 721 is completely in place.

[0108] In order to ensure the coaxiality of the slot 631 and the plug 721 after being inserted, in an embodiment, in the direction from bottom to top, the inner diameter of the slot 631 and / or the outer diameter of the plug 721 is gradually reduced. In this way, the centering can be gradually realized during the insertion of the slot 631 and the plug 721.

[0109] The slot depth of the slot 631 in the above-mentioned embodiment is not less than the convex height of the plug 721, which ensures that the plug 721 can be completely inserted into the slot 631.

[0110] The above-mentioned slot 631 is located in the middle of the lower end of the movable plug 630, ensuring that the central axis of the slot 631 is collinear with the central axis of the movable plug 630, and further ensuring that the central axis of the movable plug 630 is collinear with the central axis of the convex shaft 720. The central axis of the movable plug 630 is also its rotation axis, and the central axis of the convex shaft 720 is also its rotation axis.

[0111] In addition, the depth of the slot 631 is less than the travel of the movable plug 630 in the receiving groove 614. In this way, sufficient space is reserved in the receiving groove 614 for the movable plug 630 to move before the plug 721 and the block 631 are fully plugged in.

[0112] At least the upper section of the convex shaft 720 directly constitutes the block 721. Alternatively, the upper end of the convex shaft 720 is convexly formed to form the block 721. In an embodiment, the convex shaft 720 is hollow to form a through hole 722 extending vertically. The lower section of the through hole 722 constitutes a connecting hole section. The connecting hole section is provided for screwing with a screwing member to achieve screwing fixation of the convex shaft 720 with other components in the driving assembly 700. At this time, the inner wall of the through hole 722 is convexly provided with a support rib 723. The support rib 723 extends upward from the lower end of the through hole 722 to the upper end of the through hole 722 to define a mounting hole section at the interval. The driving assembly 700 further comprises a sealing block 724. The sealing block 724 is plugged into the mounting hole section and supported on the upper end of the support rib 723. The sealing block 724 is generally made of rubber or other structures, which can seal the upper end of the through hole 722, so that debris generated during screwing of the screwing member with the screwing hole section cannot leak out through the mounting hole section.

[0113] In addition, when the bottom shell 810 is provided as described above, in order to facilitate the docking of the block 721 in the convex shaft 720 and the slot 631 of the movable plug 630, the bottom shell 810 is provided with an axial hole for the convex shaft 720 to pass through. Specifically, the bottom shell 810 can be formed with a protrusion at the hole rim near the axial hole by, for example, flanging, detachable connection, one-piece injection molding, etc.

[0114] When the impeller assembly 600 is placed in the mounting cavity, the protrusion at least partially extends into the receiving groove 614 of the impeller sleeve 610, so that a relatively tortuous interference structure can be formed between the mounting cavity of the bottom shell 810, the receiving groove 614 of the impeller sleeve 610, and the outer wall of the convex shaft 720. This interference structure helps to prevent food falling into the mounting cavity of the bottom shell 810 from entering the plug-in fitting of the convex shaft 720 and the movable plug 630. In turn, it helps to improve the docking of the driving assembly 700 and the impeller assembly 600 with higher quality.

[0115] In addition, based on one or more of the above embodiments, further, the pet feeder can further comprise a health-care product feeding device 900. The health-care product feeding device 900 is generally distinguished from the food bin 300. For example Figures 1 to 7 In the structure shown, the health-care product feeding device 900 is arranged on the top of the food bin 300.

[0116] The health-care product feeding device 900 can be arranged separately from the top cover 200 and then connected in a detachable or non-detachable manner. Alternatively, the health-care product feeding device 900 can directly constitute the top cover 200 and be arranged on the top of the main cylinder 100.

[0117] It should be noted that the health-care product feeding device 900, i.e., a mechanism for feeding health-care products to pets in a timed and quantitative manner, can be designed in a structure such as the food bin 300, the feeding device, and the food outlet passage 500, without limitation.

[0118] The above only describes preferred embodiments of the present application, and does not limit the patent range of the present application. Any equivalent structural transformation, direct / indirect application in other related technical fields, or the like, which is made under the inventive concept of the present application, using the content of the present application specification and drawings, is included in the patent protection range of the present application.
