[0249] The pressurizing portion (284) of the middle plate (280) is arranged to be in contact with the weight sensor (244). When a pet is placed on the upper side of the upper part (250), at least one of the plurality of pressurizing portions (284) can press the corresponding weight sensor (244). Accordingly, the weight of the pet placed on the upper side of the upper part (250) can be measured.

[0250] When force is applied to one side of the upper part (250), the upper part (250) in the area where the force is applied can move downward. At this time, the middle plate (280) arranged on one side also moves downward.

[0251] The air purifier (1) can perform air purification operation even when a pet is positioned on the seat device (200) by positioning the seat device (200) on the upper side of the main body (100).

[0252] Furthermore, by placing the resting area in a high space, we increased the possibility of pets entering the resting area. In particular, reflecting the characteristic of cats who like to climb to high places, we incorporated a space for cats to rest on top of the air purifier (1).

[0253] The height of the seat device (200) is similar to that of a bed, providing a resting space at eye level with the cat owner. This has the effect of enhancing the happiness and comfort of the pet.

[0254] According to the present disclosure, there is an advantage in that a single product simultaneously provides a resting space for pets and air purification functions, thereby eliminating the need for additional products.

[0255] In addition, reflecting the characteristics of cats that like to wrap themselves around the body and prefer warm spaces, the air purifier (1) provides a heating function using a heater (264).

[0256] Additionally, functions such as measuring a cat's weight and usage time are applied to the space, allowing the cat's daily life patterns to be naturally measured, and cat owners can utilize this information to manage their cat's health. The measured data can be checked and managed through the application.

[0257] The air purifier (1) features various functions, such as pet weight measurement, heating function, and usage time measurement, and can analyze the pet's condition and lifestyle patterns. Users can run the application on their mobile devices to check real-time weight measurement results, weight measurement history, and other information, and control the heating temperature.

[0262] The seat case (1020) may be circular. The circular seat case (1020) can protect the inner cushion (1010) and maintain the overall shape of the seat (254).

[0263] The seat (254) can implement an outer round design shape by including a seat case (1020) that wraps the inner cushion (1010) in a circular shape. Since the outer edge of the seat (254) is round without corners, it can prevent the pet from hitting the corners when getting on or off the seat device (200).

[0264] To better maintain a certain shape, the cushion (1010) may be of the pad type.

[0265] A plurality of ribs (1025) spaced apart in the circumferential direction can be formed on the inner surface (1021) of the seat case (1020).

[0266] The cushion (1010) can be manufactured from a foamed resin such as polyurethane. The cushion (1010) can be manufactured as a molded product with a shape that includes a perforated pattern that can improve thermal efficiency.

[0267] After the seat case (1020) is fixed in the mold, a foam resin liquid can be injected. For example, a polyurethane resin can be injected into the mold.

[0268] When foam-molded, the polyurethane expands and adheres to the ribs (1025) of the seat case (1020), thereby producing a molded product. The polyurethane expands to the inner surface (1021) of the seat case (1020), thereby forming an outer surface (1011) of the cushion (1010) corresponding to the inner surface (1021) of the seat case (1020).

[0269] Through this process, a cushion assembly (1000) including a cushion (1010) and a seat case (1020) can be manufactured.

[0270] Figures 10 to 12 illustrate a cushion assembly (1000) within a seat (254). The seat (254) may include a seat case (1020) and a cover that surrounds the cushion (1010). For example, the seat (254) may include a fabric cover that is easy to clean, and the fabric cover may surround the seat case (1020) and the cushion (1010).

[0271] In the case where only a cushion (1010) made of soft material is available, it is not easy to put a fabric cover on the cushion (1010). However, if a seat case (1020) surrounds the cushion (1010), the fabric cover can be put on the solid seat case (1020). Accordingly, the workability during manufacturing is improved. In addition, since the user can easily put the fabric cover back on the seat case (1020) and the cushion (1010) after washing, there is an advantage in that the seat (252) is also easy to manage.

[0272] The inner cover (276) of the seat cover (266) surrounds the outer perimeter of the seat (254) and can form a resting space (267) for the pet on the upper side of the seat (254). A heater (264) is arranged on the lower side of the seat (254) to provide a heating function.

[0273] The sheet (254) can be detachably mounted on the upper side of the mounting plate (258). In addition, the sheet (254) can be detached from the upper side of the mounting plate (258).

[0274] The sheet (254) includes a plurality of apertures (1015). A plurality of apertures (1015) may be formed in the cushion (1010).

[0275] By forming a hole (1015) in the cushion (1010), heat can be better transferred. When using the heating function, the seat device (200) can improve energy efficiency by including a seat (254) with high heat transfer efficiency.

[0276] The sheet (254) may include a sensing protrusion (256) protruding downward from the lower surface. The sensing protrusion (256) may be coupled to at least one of the plurality of apertures (1015).

[0277] FIG. 13 is an enlarged view of a cushion fixing structure of a seat according to one embodiment of the present disclosure.

[0278] A center hole (260) that is opened downward may be formed in the center of the mounting plate (258). The sensing protrusion (256) may be inserted into the center hole (260) formed in the mounting plate (258).

[0279] The air purifier (1) can detect whether a pet has climbed onto the seat device (200) through a weight sensor (244) and measure the pet's rest time.

[0280] In addition, the air purifier (1) can measure the heating function usage time by measuring the time the pet is on the seat (252) through the weight sensor (244) while the heating function is in operation.

[0281] Users can manage their pet's heating function usage time through the app. Furthermore, users can prevent low-temperature burns in their pets by adjusting the target temperature of the heating function based on the usage time.

[0282] In addition, the air purifier (1) can prevent pets from being exposed directly on the hot mounting plate (258) by providing a heating function only when the seat (254) is mounted.

[0283] The seat device (200) may include a confirmation sensor (262) that confirms when the seat (254) is mounted on the mounting plate (258).

[0284] The confirmation sensor (262) is placed on the lower side of the mounting plate (258). The detection protrusion (256) can be inserted into a central hole (260) formed in the central portion of the mounting plate (258). One side of the central hole (260) can be open. The confirmation sensor (262) can be placed on the open side of the central hole (260).

[0285] When the sheet (254) is placed on the upper side of the mounting plate (258), the detection protrusion (256) can come into contact with one side of the confirmation sensor (262). Therefore, the confirmation sensor (262) can check whether the sheet (254) is placed or not by whether it comes into contact with the detection protrusion (256).

[0286] Alternatively, the confirmation sensor (262) may be a sensor that detects pressure. The confirmation sensor (262) can detect the pressure applied to the detection protrusion (256) and check whether the sheet (254) is positioned.

[0287] If the detection protrusion (256) and / or the confirmation sensor (262) are exposed to the outside, the heating function may malfunction if the pet presses on the exposed detection protrusion (256) or confirmation sensor (262).

[0288] In the present disclosure, the detection protrusion (256) is inserted into the central hole (260), and the confirmation sensor (262) is in contact with the detection protrusion (256) on the lower side of the sheet (254) and is not exposed to the outside. Therefore, an accident that may occur due to a pet accidentally activating the heating function in the absence of the sheet (254) can be prevented.

[0289] Meanwhile, corresponding to the position of the central hole (260), the sensing protrusion (256) can be coupled to the hole (1015b) formed in the center of the cushion (1010) among the plurality of holes (1015). Accordingly, the sensing protrusion (256) can be inserted into the central hole (260).

[0290] According to an embodiment, the hole (1015b) to which the sensing protrusion (256) is coupled may be larger than the other holes (1015a). In addition, the hole (1015b) to which the sensing protrusion (256) is coupled may be the largest among the plurality of holes (1015).

[0291] The cushion assembly (1000) may include a cushion (1010), a seat case (1020), and a detection protrusion (256). In addition, a hole through which the detection protrusion (256) passes may be formed in the lower part of the fabric cover. Alternatively, the fabric cover may wrap the entire upper surface and side surfaces of the cushion assembly (1000), and may wrap only the outer portion of the lower surface of the cushion assembly (1000).

[0292] Meanwhile, the detection protrusion (256) can be inserted into the hole (1015b) of the completed cushion (1010).

[0293] In another embodiment, the sensor protrusion (256) may be manufactured integrally with the cushion (1010) and the seat case (1020).

[0294] For example, after the seat case (1020) and the sensor protrusion (256) are fixed in the mold, a foam resin liquid that becomes the material of the cushion (1010) can be injected. For example, a polyurethane resin can be injected into the mold.

[0295] When foamed, the polyurethane expands and adheres to the ribs (1025) and the sensor protrusions (256) of the seat case (1020).

[0296] Through this process, a cushion assembly (1000) including a cushion (1010), a seat case (1020), and a detection protrusion (256) can be manufactured.

[0297] Meanwhile, the sensing protrusion (256) located at the bottom of the cushion (1010) is coupled to the central hole (260) located at the center of the fixing plate (258), thereby fixing the seat (254) to the fixing plate (258). Accordingly, even if the pet moves on the seat (254), the seat (254) is well fixed without being rolled, thereby improving safety.

[0298] Meanwhile, the plurality of apertures (1050) may have a hole pattern in which a plurality of circular holes are spaced apart longitudinally and transversely.

[0299] A cushion (1010) with a hole pattern can improve energy efficiency by transferring heat more quickly than when there is no hole pattern. When the heater (264) is operated at a starting temperature of 19 degrees Celsius and the time taken to reach a surface temperature of 30 degrees Celsius is measured, it takes 310 seconds when there is a hole pattern, which is faster than 428 seconds when there is no hole pattern.

[0300] Meanwhile, the plurality of apertures (1050) may have a stripe pattern.

[0301] FIG. 14 is a top view of a cushion structure of another embodiment of the present disclosure, illustrating a cushion (1300) having a stripe pattern (1315).

[0302] A hole (1315) having a long vertical or horizontal stripe pattern can be formed in a pad (1310) made of a soft material.

[0303] Figure 15 is a diagram showing the results of an experiment on temperature changes by cushion pattern when the heating function is used.

[0304] Fig. 15 shows the time taken for the temperature on the upper side of the sheet (252) to reach 40 degrees when the heater (264) is operated at low temperature, when the cushion (1010) has no holes or patterns, has the hole pattern of Fig. 10, and has the stripe pattern of Fig. 15.

[0305] When the stripe pattern was used, it was slightly faster at 16 minutes than when there was no pattern (17 minutes). When the hole pattern was used, it was 13 minutes, which was faster than when there was a stripe pattern or no pattern.

[0306] The hole pattern has the advantage of forming a large number of circular holes without the cushion (1010) becoming sagging. This improves heat transfer efficiency and also has the advantage of uniformly increasing and maintaining the temperature of the entire cushion (1010).

[0307] Although the preferred embodiments of the present disclosure have been illustrated and described above, the present disclosure is not limited to the specific embodiments described above, and it goes without saying that various modifications can be made by a person having ordinary skill in the art to which the present disclosure pertains without departing from the gist of the present disclosure as claimed in the claims.
