Description

air purifier

[0001] The present disclosure relates to an air purifier, and more particularly, to an air purifier having a sheet device disposed on the upper side for discharging purified air.

[0002] Recently, the number of households raising pets is increasing.

[0003] When pets live indoors, their fur, dander, and allergens float in the air. This can degrade indoor air quality, negatively impacting the health of both humans and pets.

[0004] On the other hand, as interest in the health and happiness of pets increases, it is becoming more important to regularly monitor and manage the health of pets.

[0005] To maintain your pet's health, regular monitoring, including weighing, is essential. Conventional scales require pets to step onto the scale, which can be stressful. Furthermore, accurate weight measurements are difficult to obtain if the pet is moving.

[0006] For the purpose of providing pleasant air in indoor spaces, Korean registered patent KR 10-2600644 B1 discloses an air purifier having an outlet formed at the top.

[0007] However, in households where pets such as cats live in the area where the air purifier is installed, the pets may rest in the upper area of ​​the air purifier where the outlet is formed, which may interfere with the operation of the air purifier or block the air flow.

[0008] Additionally, there is a spatial burden of having to place the scale separately from the air purifier.

[0009] The present disclosure aims to solve the above-mentioned and other problems.

[0010] That is, the goal is to provide an air purifier that creates a space where pets can rest without interfering with the function of the air purifier.

[0011] Another purpose is to provide an air purifier that can measure the weight of a resting pet.

At this time, a first elastic member (296) may be placed between the bushing (290) and the middle plate (280). The first elastic member (296) may maintain the arrangement of the middle plate (280).

[0269] The bushing (290) includes a bushing lower portion (294) that is coupled with the protrusion (242) and a bushing upper portion (292) that is in contact with the upper end of the first elastic member (296). The bushing upper portion (292) may have a wider diameter than the bushing lower portion (294). The first elastic member (296) may be arranged to be in contact with the lower surface of the bushing upper portion (292).

[0270] The first elastic member (296) is placed between the upper part of the bushing (292) and the middle plate (280). Therefore, the first elastic member (296) can press the middle plate (280) downward.

[0271] Fig. 13 is a drawing illustrating a state in which an upper part is coupled to a lower part according to one embodiment of the present invention. Referring to Fig. 13, a structure in which the upper part is positioned above the lower part will be described.

[0272] The upper part (250) is positioned above the lower part (210). The positioning of the upper part (250) can be maintained by the middle plate (280), the protrusion (242), and the bushing (290). The upper part (250) is positioned so as to be able to move up and down on the upper side of the lower part (210).

[0273] The middle plate (280) is positioned apart from the printed circuit board (246). Therefore, even when the upper part (250) moves up and down, the middle plate (280) does not come into contact with the printed circuit board (246).

[0274] The pressurizing portion (284) of the middle plate (280) is placed in contact with the 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 pressurize the corresponding sensor (244). Accordingly, the weight of the pet placed on the upper side of the upper part (250) can be measured.

[0275] The first elastic member (296) can apply downward force to the middle plate (280). Therefore, when no separate force is applied to the seat cover (266), the arrangement of the upper part (250) positioned above the lower part (210) can be maintained consistently.

[0276] A stopper (274) may be placed on the inner circumference of the outer cover (268). The stopper (274) is placed on the lower side of the middle plate (280). The stopper (274) contacts the outer circumference of the lower wall (230) of the lower part (210), thereby preventing one side of the outer cover (268) from tilting downward by a certain amount or more.

[0277] FIG. 14a is a drawing for explaining the arrangement of the upper part when no separate external force is applied to the seat device according to one embodiment of the present invention. FIG. 14b is a drawing for explaining the arrangement of the upper part when an external force is applied to one side of the seat device according to one embodiment of the present invention.

In addition, each of the first elastic members (296) positioned in opposite directions presses the middle plate (280). Therefore, the middle plate (280) or the fixing plate (258) can be placed in a horizontal state.

[0281] Fig. 14b is a drawing showing a state in which force is applied to one side of the upper part (250). Fig. 14b may show a state in which a companion animal is placed on one side of the upper part (250).

[0282] 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.

[0283] Additionally, the pressurizing portion (284) of the middle plate (280) placed in the relevant area can pressurize the sensor (244). The stopper (274) can prevent one side of the upper part (250) from tilting beyond a certain level by coming into contact with the lower part (210).

[0284] On the other hand, the upper part (250) positioned in the opposite direction on one side can move relatively upward. The middle plate (280) positioned in the opposite direction on one side can also move upward.

[0285] However, the first elastic member (296) can pressurize the middle plate (280) to prevent the middle plate (280) from coming off the protrusion (242). In addition, the upper bushing (292) of the bushing (290) can come into contact with the middle plate (280) to prevent the middle plate (280) from coming off the protrusion (242).
