[0262] FIG. 10 is a perspective view of an air purifier equipped with a sheet supporter according to an embodiment of the present disclosure.

[0263] Referring to FIG. 10, the air purifier further includes a sheet supporter (1000). The sheet supporter (1000) is positioned between the main body (100) and the sheet device (200).

[0264] The sheet supporter (1000) is installed so that its lower part contacts the upper surface of the main body (100). In addition, the sheet supporter (1000) is installed so that its upper part contacts the lower surface of the sheet device (200), thereby supporting the sheet device (200) from the lower side.

[0265] The seat device (200) is intended to provide a resting space for the pet, and the resting space must be large enough for the pet to sit or lie down. Accordingly, the width of the seat device (200) may be larger than the width of the main body (100). An air purifier with a large upper portion due to the seat device (200) may shake or tip over when the pet jumps or moves.

[0266] For example, if a pet on the seat device (200) stands tilted in one direction, the seat device (200) may tilt in one direction and may shake or overturn.

[0267] By arranging a seat supporter (1000) on the lower surface of the main body (100), the seat device (200) can be prevented from tilting, thereby preventing the main body (100) from shaking or overturning.

[0268] FIG. 11 is a perspective view of a sheet supporter according to an embodiment of the present disclosure, and FIG. 12 is a side view of a sheet supporter according to an embodiment of the present disclosure.

[0269] FIG. 13 is a top view of a sheet supporter according to an embodiment of the present disclosure, and FIG. 14 is a front view of a sheet supporter according to an embodiment of the present disclosure.

[0270] Referring to FIGS. 11 to 14, the sheet supporter and air purifier are described.

[0271] The sheet supporter (1000) includes an upper supporter (1011, 1021) that contacts the lower part of the sheet device (200), a lower supporter (1012, 1022) that contacts the upper part of the main body (100), and a middle supporter (1013, 1023) that connects the upper supporter (1011, 1021) and the lower supporter (1012, 1022).

[0272] The upper supporters (1011, 1021) and the lower supporters (1012, 1022) may each have an annular structure. Since the diameter of the sheet device (200) is larger than the diameter of the main body (100), it is preferable that the diameter of the upper supporters (1011, 1021) in contact with the sheet device (200) is larger than the diameter of the lower supporters (1012, 1022) in contact with the main body (100).

[0273] Since the diameter of the upper supporter (1011, 1021) is formed to be larger than the diameter of the lower supporter (1012, 1022), the middle supporter (1013, 1023) connecting the upper supporter (1011, 1021) and the lower supporter (1012, 1022) can be arranged at an angle from the vertical direction.

[0274] An opening (1050) is formed in the middle supporter (1013, 1023) through which clean air discharged to the outlet (112) passes. Air rising through the outlet (112) can flow to the outside through the opening (1050). A plurality of middle supports (1013, 1023) can be arranged spaced apart from each other in the circumferential direction. An opening (1050) can be formed between the spaced-apart middle supports (1013, 1023). Accordingly, the sheet supporter (1000) can support the sheet device (200) without obstructing the air flow.

[0275] The width (d1, d2) of the middle supporter (1013, 1023) may be formed to be smaller than the width (d3) of the opening (1050). The middle supporter (1013, 1023) may be manufactured to a thickness that reinforces rigidity between the upper supporter (1011, 1021) and the lower supporter (1012, 1022) while not impeding air flow.

[0276] The width (d3) of the opening (1050) may increase from the lower supporter (1012, 1022) side to the upper supporter (1011, 1021). The width (d1, d2) of the middle supporter (1013, 1023) may be formed to be smaller than the minimum value of the width (d3) of the portion (1050).

[0277] The upper width (d1) of the middle supporter (1013, 1023) may be greater than the lower width (d2) of the middle supporter (1013, 1023).

[0278] The upper supporter (1011, 1021) may have a portion of its upper surface in contact with the seat device (200). The upper supporter (1011, 1021) may include a first upper supporter (1011a, 1021a) in contact with the seat device (200) and a second upper supporter (1011b, 1021b) spaced apart from the seat device (200).

[0279] The second upper supporter (1011b, 1021b) is spaced apart from the lower body (211), and an operating space (1100) can be formed between the second upper supporter (1011b, 1021b) and the lower body (211).

[0280] The length of the middle supporter (1013, 1023) connected to the first upper supporter (1011a, 1021a) may be formed longer than the length of the middle supporter (1013, 1023) connected to the second upper supporter (1011b, 1021b).

[0281] The operating space (1100) can be formed to a size sufficient for a finger to pass through. A plurality of switches (248a, 248b, 248c) can be arranged on the lower surface of the lower body (211).

[0282] The second upper supporter (1011b, 1021b) may be positioned below the plurality of switches (248a, 248b, 248c). Accordingly, the operating space (1100) may be formed below the plurality of switches (248a, 248b, 248c).

[0283] Meanwhile, the entire lower surface of the lower supporter (1012, 1022) can be in contact with the main body (100).

[0284] The sheet supporter (1000) can be formed by combining two parts (1010, 1020). The sheet supporter (1000) can be formed by combining a first part (1010) and a second part (1020).

[0285] By combining the first part (1010) and the second part (1020), a ring-shaped structure can be formed.

[0286] FIG. 15 is an exploded view of a sheet supporter according to one embodiment of the present disclosure, showing a state in which the first part (1010) and the second part (1020) are separated.

[0287] The first part (1010) includes an upper supporter (1011), a lower supporter (1012), and a middle supporter (1013). The second part (1020) includes an upper supporter (1021), a lower supporter (1022), and a middle supporter (1023).

[0288] Magnets (1015) may be placed at both ends of the first part (1010). For example, magnets (1015) may be placed on the upper supporter (1011). Since the heights of the first upper supporter (1011a) and the second upper supporter (1011b) are different, the heights of the magnets (1015) at both ends may also be placed differently.

[0289] Magnets (1025) may also be placed at both ends of the second part (1020). For example, magnets (1025) may be placed on the upper supporter (1021). Since the heights of the first upper supporter (1021a) and the second upper supporter (1021b) are different, the heights of the magnets (1025) at both ends may also be placed differently.

[0290] Both ends of the first part (1010) and both ends of the second part (1020) can be joined by magnets (1015, 1025) to form a sheet supporter (1000).

[0291] The sheet supporter (1000) can be easily installed by applying a joining structure using magnets (1015, 1025). First, the user positions the first part (1010) and the second part (1020) on both sides of the joining portion of the main body (100) and the sheet device (200). Then, when the user pushes the first part (1010) and the second part (1020) inward, the two ends of the first part (1010) and the two ends of the second part (1020) face each other and can be joined by the magnets (1015, 1025).

[0292] According to an embodiment, some of the magnets (1015, 1025) may be replaced with metal pieces (not shown). For example, magnets (1015) may be placed at both ends of the first part (1010), metal pieces may be placed at both ends of the second part (1020), and the magnets (1015) and the metal pieces may be combined.

[0293] Alternatively, metal pieces may be placed at both ends of the first part (1010), magnets (1025) may be placed at both ends of the second part (1020), and the magnets (1025) and the metal pieces may be combined.

[0294] Alternatively, a magnet (1015) may be placed at one end of the first part (1010) and a metal piece may be placed at the other end. Corresponding to the first part (1010), a metal piece and a magnet (1025) may be placed at both ends of the second part (1020).

[0295] According to an embodiment, a mounting groove (not shown) may be formed on the lower surface of the lower wall (230) to better secure the upper supporter (1011, 1021). In addition, a mounting groove (not shown) may be formed on the upper surface of the main body (100) (e.g., the upper surface of the main cover (116)) to which the lower supporter (1012, 1022) is mounted.

[0296] FIG. 16 is a perspective view of an air purifier equipped with a sheet supporter according to an embodiment of the present disclosure, and FIG. 17 is a bottom view of a sheet device equipped with a sheet supporter according to an embodiment of the present disclosure.

[0305] Magnets (1035) are arranged at both ends of the first part (1030). The magnets (1035) may be formed to be long in the vertical direction. The length of the magnets (1035) may correspond to the length of the adjacent middle supporter (1033). The middle supporter (1033) connects the upper supporter (1031) and the lower supporter (1032) and forms an opening (1050) through which air can pass.

[0306] A magnet (1035a) of one end may have a different length from a magnet (1035b) of the other end. The length of the middle supporter (1033) connected to the first upper supporter (1031a) may be formed to be longer than the length of the middle supporter (1033) connected to the second upper supporter (1031b). The magnet (1035a) connected to the first upper supporter (1031a) may be formed to be longer than the magnet (1035b) connected to the upper supporter (1031b).

[0307] Magnets (1045) are arranged at both ends of the second part (1040). The magnets (1045) may be formed to be long in the vertical direction. The length of the magnets (1045) may correspond to the length of the adjacent middle supporter (1043). The middle supporter (1043) connects the upper supporter (1041) and the lower supporter (1042) and forms an opening (1050) through which air can pass.

[0308] A magnet (1045a) of one end may have a different length from a magnet (1045b) of the other end. The length of the middle supporter (1043) connected to the first upper supporter (1041a) may be formed longer than the length of the middle supporter (1043) connected to the second upper supporter (1041b).
