Technology Field
[0001] The present invention relates to a surface flattening device, and more specifically, to a surface flattening device for flattening the surface of HVAC activated carbon. Background Technology
[0003] EMERGENCY HVAC (Heating, Ventilation, and Air Conditioning) systems utilize activated carbon filters to perform rapid and effective air purification in emergency situations.
[0004] Activated carbon is a key component that maintains air quality by adsorbing harmful gases, but it reaches a saturation state after a certain period of time and needs to be replaced.
[0005] After replacing the activated carbon filter, the activated carbon layer inside the filter may not be uniformly distributed, and may become concentrated in certain areas or create gaps.
[0006] This unbalanced condition obstructs airflow, and the adsorption efficiency of activated carbon may decrease in some sections.
[0007] In addition, if the activated carbon layer is not uniformly distributed, the load may be concentrated in specific areas, which can shorten the filter's lifespan.
[0008] In addition, if air resistance is not constant, it can lead to a decrease in HVAC system performance and an increase in energy consumption.
[0009] Therefore, it is essential to align the activated carbon layer evenly through leveling after replacing the activated carbon.
[0010] However, existing surface leveling devices had problems such as reduced durability or damaged the quality of activated carbon filters due to repetitive high-vibration operations.
[0011] In addition, repetitive high-vibration work can cause discomfort to workers and increase the risk of safety accidents. Prior art literature

[0018] In addition, the upper surface of the housing includes a flange having an opening in the center, and the connecting rod of the first shaft penetrates the opening of the flange.
[0019] In addition, the housing is characterized by including an elastic layer located on one side of the lower surface that contacts the surface to be flattened.
[0020] In addition, the above housing is characterized by having a lower surface area larger than the upper surface.
[0021] In addition, the above-mentioned catch is characterized by being cylindrical in shape, having a diameter larger than the diameter of the opening of the flange. Effects of the invention
[0023] A surface leveling device according to one embodiment of the present invention can perform a compaction action by converting the reciprocating motion of an electric breaker into linear motion through an axis, while also improving the durability of the surface leveling device by absorbing impact energy caused by the vibration of the axis during reciprocating motion with an elastic member.

[0031] The present invention relates to a surface leveling device. The surface leveling device may be used for surface leveling of activated carbon, surface leveling of construction materials, or surface leveling of the ground. The present invention will be described below through an embodiment applied to surface leveling of activated carbon.

[0033] Hereinafter, the surface flattening apparatus of the present invention will be described with reference to FIGS. 1 to 5.
[0034] A surface flattening device (100) according to one embodiment of the present invention includes a housing (101), a first shaft (102), a second shaft (103), and an elastic member (104).
[0035] For example, the housing (101) is composed of an upper surface, a lower surface, and a side surface and has an internal space (204).
[0036] The housing (101) can be provided in a cylindrical shape, for example.
[0037] For example, the first shaft (102) includes a fastening part (301) connected to an electric breaker (501), a locking part (303) located in the internal space (204) of the housing, a connecting rod (302) connecting the fastening part (301) and the locking part (303) and penetrating the upper surface of the housing, and a buffer part (304) located on one side of the locking part (303) and having an insertion space (305).
[0038] For example, the second shaft (103) includes an inlet part (401) that is inserted into the insertion space (305) of the buffer part (304) of the first shaft (102), and a plate (402) that is coupled to the inlet part (401) and contacts the lower surface of the housing (101).
[0039] For example, the elastic member (104) is located in the internal space (204) of the housing (101) and is located between the catch portion (303) of the first shaft (102) and the plate (402) of the second shaft (103).
[0040] Hereinafter, the roles and structures of each component of the housing (101), the first shaft (102), the second shaft (103), and the elastic member (104) are explained in more detail.
[0041] 1. Housing (101)
[0042] The housing (101) is composed of an upper surface, a lower surface, and a side surface to form an internal space (204). A locking part (303) and a cushioning part (304) of a first shaft (102), a second shaft (103), and an elastic member (104) may be located in the internal space (204).
[0043] For example, the upper surface of the housing (101) is composed of a flange (201) having an opening in the center, and the connecting rod (302) of the first shaft (102) can pass through the opening of the flange (201). In the above, the meaning of the term "pass through" may include a state in which the connecting rod (302) passes through the opening of the flange (201). Accordingly, the connecting rod (302) may be inserted into the opening of the flange (302).
[0044] For example, the lower surface of the housing (101) may represent one side of a compaction plate (202) that compacts the surface in contact with the surface of the object to be flattened.
[0045] For example, the housing (101) may include an elastic layer (203) located on one side of the lower surface that contacts the surface to be flattened. For example, the elastic layer (203) may be located on the side facing the surface to be flattened of the compaction plate (202). The elastic layer (203) may serve to mitigate impact during the flattening operation and prevent damage to the activated carbon filter.
[0046] For example, the elastic layer (203) may be formed of a rubber or silicone material having a thickness within the range of 5 mm to 10 mm. By including the elastic layer (203) on one side of the lower surface that contacts the surface to be flattened, the housing (101) can mitigate the impact applied to the surface of the activated carbon during the surface flattening operation of the activated carbon and more effectively prevent damage to the activated carbon filter.
[0047] For example, the housing (101) may be designed so that the lower surface has a larger area than the upper surface. Designing the lower surface of the housing (101) to have a larger area than the upper surface may be advantageous for a worker to perform stable leveling work.
[0048] For example, the side of the housing (101) seals the internal space (204) of the housing (101) and serves to guide the movement of the first shaft (102), the second shaft (103), and the elastic member (104).
[0049] 2. First shaft (102)
[0050] The first shaft (102) includes a fastening part (301) connected to an electric breaker (501), a locking part (303) located in the internal space of the housing (101), a connecting rod (302) connecting the fastening part (301) and the locking part (303) and penetrating the upper surface of the housing (101), and a buffer part (304) located on one side of the locking part (303) and having an insertion space (305).
[0051] For example, the connecting part (301) serves to transmit the reciprocating motion of the electric breaker (501) to the locking part (303) through the connecting rod (302). Meanwhile, the electric breaker (501) is not particularly limited and a known electric breaker can be used. In addition, the method of connecting with the electric breaker (501) is also not particularly limited and the electric breaker (501) and the first shaft (102) can be connected by a known connecting method.
[0052] For example, the catch portion (303) may be cylindrical in shape having a diameter larger than the opening diameter of the flange (201). The catch portion (303) serves to transmit the reciprocating motion of the connecting rod (302) to the second shaft (103) through the elastic member (104). Since the catch portion (303) is formed in a cylindrical shape having a diameter larger than the opening diameter of the flange (201), it can effectively prevent the first shaft (102) from detaching from the housing (101).
[0053] 3. Second shaft (103)
[0054] The second shaft (103) includes an inlet portion (401) that is inserted into the insertion space (305) of the buffer portion (304) of the first shaft (102), and a plate (402) that is coupled to the inlet portion (401) and contacts the lower surface of the housing (101).
[0055] For example, a plate (402) in contact with the lower surface of the housing (101) can be vertically connected to the inlet (401).
[0056] For example, when the elastic member contracts due to the reciprocating motion of the first shaft (102), the length of the inlet portion (401) of the second shaft (103) located in the insertion space (305) of the cushioning portion (304) may be increased. Additionally, when the contracted elastic member recovers, the length of the inlet portion (401) of the second shaft (103) located in the insertion space (305) of the cushioning portion (304) of the first shaft (102) may be shortened.
[0057] For example, the plate (402) of the second shaft (103) may have a contact area with the lower surface of the housing (101) ranging from 70% to 100%. The plate (402) contacts the lower surface of the housing (101) and serves to apply pressure to the surface to be flattened to evenly distribute the activated carbon.
[0058] When the area of contact between the plate (402) of the second shaft (103) and the lower surface of the housing (101) satisfies the range of 70% to 100%, the plate (402) can evenly transmit pressure to the entire surface to be flattened through the lower surface of the housing (101), which may be advantageous for improving flattening efficiency.
[0059] 4. Elastic member (104)
[0060] The elastic member (104) is located in the internal space of the housing (101) and is positioned between the locking part (303) of the first shaft (102) and the plate (402) of the second shaft (103). The elastic member (104) serves to absorb impact energy generated during the reciprocating motion of the first shaft (102) and dampen vibrations.
[0061] The elastic member (104) can be provided as, for example, a coil spring.
[0062] For example, the non-retracted length (T0) of the spring (104) can satisfy the following formula in relation to the buffer length (S1) of the first shaft (102) and the inlet length (S2) of the second shaft (103).
[0063] [formula]
[0064] 1.5*(S1) < T0 < (S1 + S2)
[0065] When the above formula is satisfied, the spring (104) can maintain appropriate elasticity while preventing the shock absorption function from being degraded due to excessive contraction. In addition, the first shaft (102) and the second shaft (103) are properly connected so that the insertion part (401) of the second shaft (103) is prevented from detaching from the cushioning part (304) of the first shaft (102).
[0066] For example, the length (T1) of the spring (104) when compressed may be longer than the length (S1) of the cushioning portion of the first shaft (102). The length (T1) of the spring when compressed is set to be longer than the length (S1) of the cushioning portion of the first shaft, thereby allowing a constant restoring force to be maintained even when compressed.
[0067] This spring (104) design ensures sufficient elasticity to effectively absorb impact energy and effectively dampen vibrations, allowing the leveling equipment (100) to operate stably for a long time.
[0068] 5. Operating Principle
[0069] An electric breaker (501) is connected to the connecting portion (301) of the first shaft (102). When the electric breaker (501) is operated, the reciprocating motion is transmitted through the first shaft (102). The motion of the first shaft (102) is transmitted to the second shaft (103) through the spring (104). The spring (104) absorbs the shock and dampens the motion, transmitting it to the plate (402) of the second shaft (103). The plate (402) applies uniform pressure to the surface through the lower surface of the housing (101) to evenly distribute the activated carbon and perform a flattening operation.
