[0221] The upper end of the outer cover 268 can be spaced apart from the upper side of the mounting plate 258. The height at which the upper end of the outer cover 268 is separated from the mounting plate 258 can vary depending on the position.

[0222] The upper end of the outer cover 268 may have a minimum height in a first position 269a and a maximum height in a second position 269b located on the opposite side of the first position 269a.

[0223] The outer cover 268 can form a space 267 for the pet on the upper side of the mounting plate 258.

[0224] The outer cover 268 may have a structure that opens to the upper side of the space 267. The outer cover 268 may have a structure that opens to the upper side and the circumferential side of the space 267.

[0225] The outer cover 268 may include a first outer cover 268a extending toward the upper side of the mounting plate 258 and a second outer cover 268b extending toward the lower side of the first outer cover 268a.

[0226] The first outer cover 268a and the second outer cover 268b can be integrally formed. The first outer cover 268a and the second outer cover 268b can be formed as separable structures. A portion of the first outer cover 268a and the second outer cover 268b can be integrally formed.

[0227] The outer cover 268 can form a curved surface that bulges outward in a radial direction. The outer peripheral surfaces of the first outer cover 268a and the second outer cover 268b can each form the same curved surface.

[0228] The second outer cover 268b extends upward from the upper end of the lower wall 230. The second outer cover 268b extends radially outward and upward. The outer peripheral surface of the second outer cover 268b may be formed by a convex curved surface.

[0229] The second outer cover 268b can have the same height in the circumferential direction.

[0230] The first outer cover 268a may have a structure that extends upward from the second outer cover 268b.

[0231] The first outer cover 268a can form a space 267 for the pet on the upper side of the mounting plate 258. The first outer cover 268a can guide the air flowing upward through the exhaust port 112 of the main body 100 to flow out of the space 267.

[0232] The first outer cover 268a may have a structure in which the height varies along the perimeter. The height at which the upper end of the first outer cover 268a is separated from the upward-facing side of the mounting plate 258 may be different from each other along the perimeter of the first outer cover 268a.

[0233] For example, the first position 269a of the first outer cover 268a is formed with the minimum height, and the second position 269b of the first outer cover 268b is formed with the maximum height.

[0240] The lower end portion 276b of the inner cover 276 can be positioned at the same location along the circumferential surface. The upper end portion 276a of the inner cover 276 can be positioned at different locations along the circumferential surface.

[0241] The mounting plate 258 forms a flat surface. A seat 254 is disposed on the upper side of the mounting plate 258. A central hole 260 with a downward opening is formed in the center of the mounting plate 258.

[0242] The base 254 may be made of a material that cushions impact and is partially deformable. The base 254 may have a plurality of through holes inside to transfer heat to the mounting plate 258.

[0243] The base 254 includes a sensing protrusion 256 that protrudes downward from its lower surface. The sensing protrusion 256 can be inserted into a central hole 260 formed on the mounting plate 258.

[0244] The mounting device 200 may include a confirmation sensor 262 that confirms the mounting status when the mounting 254 is mounted on the mounting plate 258. The confirmation sensor 262 is disposed on the underside of the mounting plate 258.

[0245] When the base 254 is positioned on the upper side of the mounting plate 258, the sensing protrusion 256 can contact one side of the confirmation sensor 262. Therefore, the confirmation sensor 262 can confirm whether the base 254 is present by whether it contacts the sensing protrusion 256.

[0247] The seat device 200 may include a fixing device 232, which can keep the seat device 200 engaged with the main body 100 or disengage it.

[0248] The fixing device 232 includes a hook 236 movably disposed inside the seat device 200 and a button 234 for changing the position of the hook 236.

[0249] The fixing device 232 includes a hook guide 238 disposed inside the seat device 200 and guiding the movement of the hook 236, and an elastic member 240 disposed between the hook guide 238 and the hook 236.

[0250] Figure 9 From and Figure 8 Cross-sectional views of the seat assembly taken from different directions are used to illustrate the connection relationship between the upper and lower parts. (Refer to...) Figure 9 Explain the structure of the upper and lower parts.

[0251] The upper portion 250 is held in its position above the lower portion 210 by means of a bushing 290. The upper portion 250 is configured to move vertically above the lower portion 210. The bushing 290 restricts the vertical movement of the upper portion 250.

[0252] With the upper portion 250 positioned above the lower portion 210, the bushing 290 can be mounted on the protrusion 242 formed on the lower portion 210. When the bushing 290 is mounted on the protrusion 242, the intermediate plate 280 of the upper portion 250 can be configured to contact the weight sensor 244 of the lower portion 210.

[0253] The intermediate plate 280 can be fixedly configured on the inside of the seat cover 266.

[0254] When the upper part 250 is positioned above the lower part 210, the pressure portion 284 of the intermediate plate 280 can be configured to contact the upper side of the weight sensor 244.

[0255] The upper part 250 is positioned above the lower part 210. The upper part 250 is held in place by the intermediate plate 280, the protrusion 242, and the bushing 290. The upper part 250 is positioned above the lower part 210 so that it can move vertically.

[0256] The intermediate plate 280 is configured separately from the printed circuit board 246. Therefore, even when the upper part 250 moves vertically, the intermediate plate 280 will not come into contact with the printed circuit board 246.

[0257] The pressure section 284 of the intermediate plate 280 is configured to contact the weight sensor 244. When the pet is located on the upper side of the upper portion 250, at least one of the plurality of pressure sections 284 can apply pressure to the corresponding weight sensor 244. Therefore, the weight of the pet located on the upper side of the upper portion 250 can be measured.

[0258] When a force is applied to one side of the upward portion 250, the upper portion 250 of the area to which the force is applied can move downward. At this time, the intermediate plate 280 disposed on one side also moves downward.

[0259] When the air purifier 1 is located on the upper side of the main body 100 and the pet is located on the seat 200, it can also perform air purification operation.

[0260] Furthermore, by placing the resting space at a higher elevation, the likelihood of pets entering the resting area is further increased. In particular, reflecting the characteristics of cats who like to climb to high places, the upper part of the air purifier 1 incorporates a space shape where cats can rest.

[0261] The seat 200 is at a height similar to that of a bed, providing a resting space at eye level with the pet owner. This increases the pet's happiness and comfort.

[0262] According to this utility model, a single product can provide both a resting space for pets and an air purification function, with the advantage of not requiring the use of other products.

[0263] In addition, reflecting cats' love of curling up and warm spaces, the air purifier 1 provides a heating function using the heater 264.

[0264] In addition, the device incorporates functions such as measuring cat weight and usage time, naturally tracking the cat's daily routines. Cat owners can use this information for their cat's health management. The measured data can be viewed and managed through the app.

[0265] The air purifier 1 offers various functions such as pet weight measurement, heating, and usage time measurement, and can analyze the pet's condition and lifestyle. Users can run an application on their mobile devices to check real-time weight measurement results, weight measurement history, and control the heating temperature.

[0266] Figure 10 This is a perspective view of a seat according to an embodiment of the present invention. Figure 11 This is an exploded perspective view of a seat according to an embodiment of the present invention.

[0267] Figure 12 This is a side sectional view of a seat device according to an embodiment of the present invention.

[0268] Reference Figures 10 to 12 Seat 254 includes a seat cushion 1010. The seat cushion 1010 provides elasticity to allow the pet to sit or lie comfortably. The seat cushion 1010 can be made of a soft and elastic material. For example, the seat cushion 1010 can be made of materials such as urethane, foam, or polyurethane (PU).

[0269] The seat 254 includes a seat housing 1020 surrounding the seat cushion 1010. The seat housing 1020 may be an injection-molded material of a rigid material. Alternatively, the seat 1020 may be made of metal.

[0270] The seat housing 1020 can be annular. The annular seat housing 1020 can protect the inner seat cushion 1010 and maintain the overall shape of the seat 254.

[0271] The seat 254 may include a seat housing 1020 that surrounds the inner side of the cushion 1010 in a ring, thereby achieving an arc-shaped design. Because the outer contour of the seat 254 is an arc-shaped shape without sharp edges, it can prevent pets from climbing onto the seat 200 or bumping into sharp edges when getting off the seat 200.

[0272] To better maintain a certain shape, the seat cushion 1010 can be a pad type.

[0273] The inner circumferential surface 1021 of the housing 1020 may be formed with a plurality of ribs 1025 spaced apart along the circumferential direction.

[0274] The cushion 1010 can be made of foamed resin such as polyurethane. The cushion 1010 can be molded into a shape that includes a through-hole pattern that can improve thermal efficiency.

[0275] Foaming resin liquid can be injected after the housing 1020 is fixed in the mold. For example, polyurethane resin can be injected into the mold.

[0276] During foaming, the polyurethane expands and adheres to the ribs 1025 of the seat housing 1020 to form a molded article. The polyurethane expands to the inner circumferential surface 1021 of the seat housing 1020, thereby forming the outer circumferential surface 1011 of the cushion 1010 corresponding to the inner circumferential surface 1021 of the seat housing 1020.

[0277] Through this process, a seat assembly 1000, including a seat cushion 1010 and a seat housing 1020, can be manufactured.

[0278] Figures 10 to 12 An example is shown of a seat cushion assembly 1000 inside seat 254. Seat 254 may include a cover that encloses seat housing 1020 and seat cushion 1010. For example, seat 254 may include an easy-to-wash fabric cover that can enclose seat housing 1020 and seat cushion 1010.

[0279] With only a soft material for the seat cushion 1010, it's not easy to put the fabric cover on it. However, since the seat housing 1020 surrounds the seat cushion 1010, the fabric cover can be put on the sturdy seat housing 1020. This improves workability during manufacturing. Furthermore, the user can easily put the fabric cover back on the seat housing 1020 and the seat cushion 1010 after washing, thus offering the advantage of easy management of the seat 252.

[0280] The inner cover 276 of the seat cover 266 can surround the outer perimeter of the seat 254 and form a resting space 267 for the pet on the upper side of the seat 254. A heater 264 can be arranged on the lower side of the seat 254 to provide heating function.

[0281] The base 254 can be detachably mounted on the upper side of the mounting plate 258. In addition, the base 254 can be detached from the mounting plate 258 upwards.

[0282] The seat 254 includes a plurality of through holes 1015. The plurality of through holes 1015 may be formed in the seat cushion 1010.

[0283] By forming through holes 1015 in the seat cushion 1010, heat can be transferred more effectively. The seat assembly 200 includes a seat 254 with high thermal conductivity when the heating function is used, thereby improving energy efficiency.

[0284] The base 254 may include a sensing protrusion 256 protruding downward from its lower surface. The sensing protrusion 256 may be coupled to at least one of the plurality of through holes 1015.

[0285] Figure 13 This is an enlarged view showing the seat cushion fixing structure of a seat according to an embodiment of the present invention.

[0286] A central hole 260 with an opening facing downwards can be formed in the center of the mounting plate 258. The sensing protrusion 256 can be inserted into the central hole 260 formed in the mounting plate 258.

[0287] The air purifier 1 can use a weight sensor 244 to detect whether a pet has climbed onto the seat 200 and measure the pet's rest time.

[0288] In addition, the air purifier 1 can measure the time the pet spends on the seat 252 using the weight sensor 244 during the heating function operation, thereby measuring the heating function usage time.

[0289] Users can manage the heating function's usage time for their pets using the app. Additionally, users can adjust the target temperature of the heating function according to the usage time, thus preventing low-temperature burns to their pets.

[0290] In addition, the air purifier 1 provides heating function only when the base 254 is installed, thereby preventing pets from being directly exposed to the hot mounting plate 258.

[0291] The mounting device 200 may include a confirmation sensor 262 that confirms the mounting status when the mounting 254 is mounted on the mounting plate 258.

[0292] The confirmation sensor 262 is disposed on the underside of the mounting plate 258. The sensing protrusion 256 can be inserted into the central hole 260 formed in the center of the mounting plate 258. One side of the central hole 260 may be open. The confirmation sensor 262 may be disposed on the open side of the central hole 260.

[0293] When the base 254 is positioned on the upper side of the mounting plate 258, the sensing protrusion 256 can contact one side of the confirmation sensor 262. Therefore, the confirmation sensor 262 can confirm whether the base 254 is present by whether it contacts the sensing protrusion 256.

[0294] Alternatively, it can be confirmed that sensor 262 is a pressure sensor. Confirming that sensor 262 can sense the pressure applied from the sensing protrusion 256 allows confirmation of whether seat 254 is configured.

[0295] If the sensing protrusion 256 and / or the confirmation sensor 262 are exposed to the outside, a pet may press the exposed sensing protrusion 256 or the confirmation sensor 262, causing the heating function to be activated erroneously.

[0296] In this invention, the sensing protrusion 256 is inserted into the central hole 260, ensuring that the sensor 262 is in contact with the sensing protrusion 256 on the underside of the seat 254 and is not exposed to the outside. Therefore, it can prevent accidents that may occur if a pet accidentally activates the heating function when the seat 254 is not in use.

[0297] On the other hand, corresponding to the position of the central hole 260, the sensing protrusion 256 can engage with the through hole 1015b formed in the center of the seat cushion 1010 among the plurality of through holes 1015. Thus, the sensing protrusion 256 can be inserted into the central hole 260.

[0298] According to an embodiment, the through hole 1015b for engaging the sensing protrusion 256 can be larger than the other through holes 1015a. Furthermore, the through hole 1015b for engaging the sensing protrusion 256 can be the largest among the plurality of through holes 1015.

[0299] The seat cushion assembly 1000 may include a seat cushion 1010, a seat housing 1020, and a sensing protrusion 256. Additionally, a hole may be formed in the lower part of the fabric cover for the sensing protrusion 256 to pass through. Alternatively, the fabric cover may cover the entire upper and side surfaces of the seat cushion assembly 1000, while only covering the outer contour of the lower surface of the seat cushion assembly 1000.

[0300] On the other hand, the sensing protrusion 256 can be inserted into the through hole 1015b of the seat cushion 1010.

[0301] In another embodiment, the sensing protrusion 256 may be integrally formed with the seat cushion 1010 and the seat housing 1020.

[0302] For example, after the seat housing 1020 and the sensing protrusion 256 are fixed in the mold, a foaming resin liquid, which is the material of the cushion 1010, can be injected. For example, polyurethane resin can be injected into the mold.

[0303] During foaming, the polyurethane expands and bonds to the ribs 1025 and sensing protrusions 256 of the housing 1020.

[0304] Through this process, a seat assembly 1000 can be manufactured, including a seat cushion 1010, a seat housing 1020, and a sensing protrusion 256.

[0305] On the other hand, the sensing protrusion 256 located at the lower end of the seat 1010 engages with the central hole 260 located at the center of the mounting plate 258, thereby fixing the seat 254 to the mounting plate 258. Therefore, even if the pet moves on the seat 254, the seat 254 is well secured and will not roll up, thereby improving safety.

[0306] On the other hand, the plurality of through holes 1050 may have a hole pattern in which a plurality of circular holes are arranged longitudinally and transversely.

[0307] The seat cushion 1010 with a perforated pattern transfers heat faster than the seat cushion without a perforated pattern, thus improving energy efficiency. Operating the heater 264 at an initial temperature of 19 degrees Celsius, the time required for the surface temperature to reach 30 degrees Celsius is 310 seconds with the perforated pattern, compared to 428 seconds without the perforated pattern.

[0308] On the other hand, the plurality of through holes 1050 can have a stripe pattern.

[0309] Figure 14 This is a top view of a seat structure according to another embodiment of the present invention, illustrating a seat 1300 having a striped pattern 1315.

[0310] Through holes 1315 with longitudinal or transverse stripe patterns can be formed on the pad 1310 of the soft material.

[0311] Figure 15 This is a graph showing the experimental results of temperature changes under different cushion patterns when the heating function is used.

[0312] Figure 15 When there are no through holes or patterns on the seat cushion 1010, it has Figure 10 When the hole pattern is present, it has Figure 14 When the striped pattern is displayed, the heater 264 is operated at low temperature, and the time it takes for the temperature on the upper side of the seat 252 to reach 40 degrees is measured.

[0313] The time was 16 minutes with the striped pattern, slightly faster than the 17 minutes without the pattern. The time was 13 minutes with the perforated pattern, faster than both the striped and unpatterned patterns.

[0314] The perforation pattern has the advantage of not making the cushion 1010 soft and weak, and it can form a large number of circular holes. Therefore, it also has the advantage of improving heat conduction efficiency and uniformly raising and maintaining the temperature of the entire cushion 1010.

[0315] Although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above. Various modifications and implementations can be made by those skilled in the art without departing from the spirit of the present invention as claimed in the claims.
