Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and more particularly, to a ventilation structure of a dryer and a dryer. Background Art

[0002] A dryer refers to a mechanical device that uses heat energy to reduce the moisture content of materials and is used for drying objects. The dryer vaporizes and escapes the moisture in the material by heating to obtain solid materials with a specified moisture content.

[0003] A dryer generally includes a fan, an electric heating element, a drying chamber, and a cabinet door. The cabinet door seals the heating space. The fan blows the air heated by the electric heating element into the drying space and flows out through the ventilation holes opened on the drying chamber, forming an air circulation channel. In this way, the air circulation channel cannot penetrate the entire heating space, resulting in poor heating effect. At the same time, a dryer usually has a chassis, and the drying chamber is arranged in the chassis. In this case, multiple ventilation holes need to be opened on the chassis and the drying chamber to allow the hot air to dissipate from the chassis to the outside of the dryer, increasing the design work and design difficulty of the dryer. Summary of the Utility Model

[0004] The purpose of this embodiment is to provide a ventilation structure of a dryer and a dryer. The air circulation channel formed by this ventilation structure penetrates the entire inner cavity, which can improve the drying effect. At the same time, the ventilation structure of this dryer does not need to add ventilation holes on the inner cavity, thereby reducing the design work of the dryer and improving the production efficiency of the dryer.

[0005] In a first aspect, this embodiment provides a ventilation structure of a dryer, including:

[0006] A chassis;

[0007] An inner cavity, arranged inside the chassis;

[0008] A air supply component, arranged on the chassis, the air supply end of the air supply component faces the inner cavity, and the air supply component conveys hot air to the inner cavity;

[0009] A cabinet door, arranged on the chassis, used to control the opening or closing of the inner cavity;

[0010] When the inner cavity is in a closed state, there is an exhaust gap between the inner cavity and the cabinet door, and the hot air conveyed by the air supply component to the inner cavity is discharged from the exhaust gap out of the dryer.

[0011] In the above implementation process, there is an exhaust gap between the cabinet door and the inner cavity when the inner cavity is in a closed state. When the air supply component works, heat is discharged to the outside of the dryer through the exhaust gap between the cabinet door and the inner cavity. Compared with the prior art method of opening through holes in the side wall of the inner cavity, the air circulation channel in this embodiment penetrates the entire inner cavity, and there is no need to open multiple through holes in the side wall of the inner cavity, reducing the design difficulty of the dryer and improving the production efficiency of the dryer.

[0012] In some embodiments, there are multiple inner cavities and multiple cabinet doors;

[0013] The air supply component is arranged behind each inner cavity, the cabinet door is arranged in front of each inner cavity, and when each inner cavity is in a closed state, there is an exhaust gap between the cabinet door of each inner cavity and each inner cavity.

[0014] In the above implementation process, there are multiple inner cavities, so that the ventilation structure of the dryer can dry multiple objects to be dried simultaneously, and different objects to be dried can be placed in different inner cavities. At the same time, each inner cavity is provided with a ventilation component and a cabinet door, and there is an exhaust gap between each inner cavity and the cabinet door of each inner cavity, so that each inner cavity forms its own independent air circulation channel, and at the same time, the independent air circulation channel of each inner cavity penetrates each inner cavity, so that the dryer has a good drying effect.

[0015] In some embodiments, the multiple inner cavities include: a first inner cavity and a second inner cavity arranged adjacent to each other;

[0016] When the first inner cavity is in a closed state, a first exhaust gap is formed between the first inner cavity and the cabinet door of the first inner cavity;

[0017] When the second inner cavity is in a closed state, a second exhaust gap is formed between the second inner cavity and the cabinet door of the second inner cavity;

[0018] The first exhaust gap and the second exhaust gap are opposite to each other;

[0019] A sealing mechanism is arranged in the first exhaust gap and / or the second exhaust gap, and the sealing mechanism is used to seal the first exhaust gap and / or the second exhaust gap.

[0020] In the above implementation process, a sealing mechanism is provided in the first exhaust gap and / or the second exhaust gap. The sealing mechanism is used to seal the first exhaust gap and / or the second exhaust gap, avoiding the mutual influence of the food in the adjacent first inner cavity and the heat in the second inner cavity through the first exhaust gap and the second exhaust gap, and also avoiding the mutual influence of the taste of the food in the first inner cavity and the material to be dried in the second inner cavity during the drying process.

[0021] In some embodiments, a first convex portion is provided at the edge of the inner cavity;

[0022] When the inner cavity is in a closed state, the first convex portion at the edge of the inner cavity and the edge of the cabinet door form the exhaust gap;

[0023] Or a second convex portion is provided at the edge of the cabinet door;

[0024] When the inner cavity is in a closed state, the edge of the inner cavity and the second convex portion of the cabinet door edge form the exhaust gap.

[0025] In the above implementation process, by providing the first convex portion or the second convex portion, an exhaust gap is formed when the cabinet door is closed. The setting process of the first convex portion and the second convex portion is simple, and based on this, the production efficiency of the dryer can be improved.

[0026] In some embodiments, a first concave portion is provided at the edge of the inner cavity;

[0027] When the inner cavity is in a closed state, the first concave portion at the edge of the inner cavity and the edge of the cabinet door form the exhaust gap;

[0028] Or a second concave portion is provided at the edge of the cabinet door. When the inner cavity is in a closed state, the edge of the inner cavity and the second concave portion of the cabinet door edge form the exhaust gap.

[0029] In the above implementation process, by controlling the shape, quantity, and distribution of the first concave portion and the second concave portion, the distribution and quantity of the exhaust gap can be controlled, thereby controlling the air circulation path of the inner cavity and improving the drying effect of the inner cavity.

[0030] In some embodiments, the plurality of inner cavities include: a first inner cavity and a second inner cavity arranged adjacent to each other;

[0031] When the first inner cavity is in a closed state, the first inner cavity and the cabinet door of the first inner cavity form a first exhaust gap;

[0032] When the second inner cavity is in a closed state, the second inner cavity and the cabinet door of the second inner cavity form a second exhaust gap;

[0033] The first exhaust gap and the second exhaust gap are opposite to each other;

[0034] A sealing mechanism is provided in the first exhaust gap and the second exhaust gap. The sealing mechanism is used to partially seal the first exhaust gap and the second exhaust gap, so that at least two sub-exhaust gaps are formed in the first exhaust gap and the second exhaust gap;

[0035] The sub-exhaust gaps in the first inner cavity and the sub-exhaust gaps in the second inner cavity are staggered.

[0036] In the above implementation process, the staggering of the sub-exhaust gaps in the first inner cavity and the sub-exhaust gaps in the second inner cavity can effectively prevent the first inner cavity and the second inner cavity from directly entering another inner cavity through the sub-exhaust gaps, prevent the odor mixing of the materials to be dried in the first inner cavity and the second inner cavity, and at the same time ensure the air circulation speed of the first inner cavity and the second inner cavity.

[0037] In some embodiments, the door hinge of the cabinet door of the first inner cavity is arranged on the side far from the second inner cavity;

[0038] The door hinge of the cabinet door of the second inner cavity is arranged on the side far from the first inner cavity.

[0039] In the above implementation process, there is usually an exhaust gap at the installation position of the door hinge. Arranging the door hinge of the cabinet door of the first inner cavity on the side far from the second inner cavity; arranging the door hinge of the cabinet door of the second inner cavity on the side far from the first inner cavity can effectively improve the anti-temperature-crossing and anti-odor-mixing effects of the dryer.

[0040] In some embodiments, the ratio of the area of the exhaust gap to the volume of the inner cavity is: 1mm 2 : 10416mm 3 ~1mm 2 : 5208mm 3 .

[0041] In some embodiments, the sealing mechanism includes: sealant and sealing strip.

[0069] Next, the technical solutions in this embodiment will be described with reference to the accompanying drawings in this embodiment.

[0070] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used for differential description and cannot be understood as indicating or implying relative importance.

[0071] See Figure 1 、 Figure 2 、 Figure 3 , this embodiment provides a ventilation structure for a dryer, including:

[0072] chassis 1;

[0073] inner cavity 2, arranged inside the chassis 1;

[0074] air supply component 9, arranged in the chassis 1, the air supply end of the air supply component 9 faces the inner cavity 2, and the air supply component 9 conveys hot air to the inner cavity 2;

[0075] cabinet door 5, arranged on the chassis 1, used to control the opening or closing of the inner cavity 2;

[0076] When the inner cavity 2 is in a closed state, there is an exhaust gap 3 between the inner cavity 2 and the cabinet door 5, and the hot air delivered by the air supply component 9 to the inner cavity 2 is discharged from the exhaust gap 3 of the dryer.

[0077] In some embodiments, a sealing mechanism 4 can be provided at one or more edges of the cabinet door 5. When the inner cavity 2 is in a closed state, the sealing mechanism 4 is clamped between the edge of the inner cavity 2 and the edge of the cabinet door 5, so that the other edges of the multiple edges of the inner cavity 2 and the cabinet door 5 except the edge where the sealing mechanism 4 is located cannot be completely fitted, forming an exhaust gap 3.

[0078] In some embodiments, a sealing mechanism 4 is provided at one or more edges of the edge of the inner cavity 2. When the inner cavity 2 is in a closed state, the sealing mechanism 4 is clamped between the edge of the inner cavity 2 and the edge of the cabinet door 5, so that the other edges of the multiple edges of the inner cavity 2 and the cabinet door 5 except the edge where the sealing mechanism 4 is located cannot be completely fitted, forming an exhaust gap 3.

[0079] See Figure 1 、 Figure 2 、 Figure 3 , which is a schematic diagram of a ventilation structure of a dryer provided by the present application. The ventilation structure of the dryer includes: a chassis 1 and an inner cavity 2, which is arranged in the chassis 1 and is used to place objects to be dried; the air supply component 9 of the dryer includes: a fan and a heating wire. The air supply component 9 is arranged behind the inner cavity 2, and a cabinet door 5 is arranged in front of the drying chamber. The air supply section of the fan is arranged towards the inner cavity 2, and the fan blows the air heated by the heating element into the inner cavity 2 to realize the drying of the objects to be dried in the inner cavity 2. A cabinet door 5 is arranged in front of the inner cavity 2, and an exhaust gap 3 is formed between the cabinet door 5 and the inner cavity 2. The exhaust gap 3 is distributed around the inner cavity 2 and the cabinet door 5. When the air supply component 9 works, the hot air is discharged from the periphery of the inner cavity 2 to the outside of the dryer through the exhaust gap 3.

[0080] In some embodiments, heat dissipation holes are opened on the chassis 1, and the function of the heat dissipation holes is to discharge the heat dissipated from the side wall of the inner cavity 2 to the outside of the chassis 1 to prevent the temperature of the dryer from being too high.

[0081] In the above implementation process, there is an exhaust gap 3 between the cabinet door 5 and the inner cavity 2 when the inner cavity 2 is in a closed state. When the air supply component 9 works, the heat is discharged to the outside of the dryer through the exhaust gap 3 between the cabinet door 5 and the inner cavity 2. Compared with the method of opening through holes on the side wall of the inner cavity 2 in the prior art, the air circulation channel in this embodiment penetrates the entire inner cavity 2, and there is no need to open multiple through holes on the side wall of the inner cavity 2, reducing the design difficulty of the dryer and improving the production efficiency of the dryer at the same time.

[0082] In some embodiments, there are multiple inner chambers 2 and multiple cabinet doors 5. A blowing component 9 is arranged behind each inner chamber 2, and a cabinet door 5 is arranged in front of each inner chamber 2. When the inner chamber 2 of each inner chamber 2 is in a closed state, there is an exhaust gap 3 between the cabinet door 5 of each inner chamber 2 and each inner chamber 2.

[0083] Exemplarily, referring to Figure 4 、 Figure 5 、 Figure 6 , which is a schematic diagram of the ventilation structure of another dryer provided in this embodiment. The dryer includes: a chassis 1, and two inner chambers 2 are arranged in the chassis 1. The two inner chambers 2 are arranged side by side. Blowing components 9 (not shown in the figure) are respectively arranged behind the two inner chambers 2, and cabinet doors 5 are respectively arranged in front of the two inner chambers 2. When the two inner chambers 2 are in a closed state, exhaust gaps 3 are respectively formed between the two inner chambers 2 and their cabinet doors 5, and the exhaust gaps 3 are respectively located above, below the cabinet door 5 and on the side where the door shaft is located.

[0084] It can be understood that the number of inner chambers 2 can also be more than two.

[0085] In the above implementation process, there are multiple inner chambers 2, so that the ventilation structure of the dryer can enable the dryer to dry multiple objects to be dried simultaneously, and different objects to be dried can be placed in different inner chambers 2. At the same time, each inner chamber 2 is provided with a ventilation component and a cabinet door 5, and there is an exhaust gap 3 between each inner chamber 2 and the cabinet door 5 of each inner chamber 2, so that an independent air circulation channel is formed for each inner chamber 2. At the same time, the independent air circulation channel of each inner chamber 2 penetrates each inner chamber 2, so that the dryer has a good drying effect.

[0086] Referring to Figure 4 、 Figure 5 、 Figure 6 , in some embodiments, the multiple inner chambers 2 include: a first inner chamber 21 and a second inner chamber 22 arranged adjacent to each other;

[0087] When the first inner chamber 21 is in a closed state, a first exhaust gap 31 is formed between the first inner chamber 21 and the cabinet door 51 of the first inner chamber;

[0088] When the second inner chamber 22 is in a closed state, a second exhaust gap 32 is formed between the second inner chamber 22 and the cabinet door 52 of the second inner chamber;

[0089] The first exhaust gap 31 and the second exhaust gap 32 are opposite to each other;

[0090] A sealing mechanism 4 is arranged in the first exhaust gap 31 and / or the second exhaust gap 32, and the sealing mechanism 4 is used to seal the first exhaust gap 31 and / or the second exhaust gap 32.

[0091] It should be noted that Figure 4 In the figure, the dashed line part is only used to indicate the positions of the first exhaust gap 31 and the second exhaust gap 32, and the first exhaust gap 31 and the second exhaust gap 32 cannot be seen in the actual front view of the dryer.

[0092] Exemplarily, referring to Figure 4 , the first inner cavity 21 and the second inner cavity 22 are arranged in parallel, and the detailed structural diagrams of the first exhaust gap 31 and the second exhaust gap 32 opposite to each other between the first inner cavity 21 and the second inner cavity 22 are as shown in Figure 7 and Figure 8 ; Figure 7 and Figure 8 are the side views of the first exhaust gap 31 and the second exhaust gap 32 respectively;

[0093] Referring to Figure 7 , it is a schematic diagram of the exhaust gap of an inner cavity provided in this embodiment. Among them, the edge of the first inner cavity 21 and the cabinet door 51 of the first inner cavity form the first exhaust gap 31, and the side wall of the second inner cavity 22 and the cabinet door 52 of the second inner cavity form the second exhaust gap 32; a sealing mechanism 4 is provided in the first exhaust gap 31.

[0094] Referring to Figure 8 , it is another schematic diagram of the exhaust gap of an inner cavity provided in this embodiment. Among them, the edge of the first inner cavity 21 and the cabinet door 51 of the first inner cavity form the first exhaust gap 31, and the side wall of the second inner cavity 22 and the cabinet door 52 of the second inner cavity form the second exhaust gap 32; sealing mechanisms 4 are provided in both the first exhaust gap 31 and the second exhaust gap 32.

[0095] In some embodiments, a sealing mechanism 4 can be provided at the edge of the cabinet door 51 of the first inner cavity. When the first inner cavity 21 is in a closed state, the sealing mechanism 4 is clamped between the edge of the first inner cavity 21 and the edge of the cabinet door 51 of the first inner cavity, so that the other edges of the first inner cavity 21 and the cabinet door 51 of the first inner cavity except the location of the sealing mechanism 4 cannot be completely attached, forming an exhaust gap 3.

[0096] In some embodiments, a sealing mechanism 4 can be provided at the edge of the cabinet door 52 of the second inner cavity. When the second inner cavity 22 is in a closed state, the sealing mechanism 4 is clamped between the edge of the second inner cavity 22 and the edge of the cabinet door 52 of the second inner cavity, so that the other edges of the second inner cavity 22 and the cabinet door 52 of the second inner cavity except the location of the sealing mechanism 4 cannot be completely attached, forming an exhaust gap 3.

[0097] In the above implementation process, a sealing mechanism 4 is provided in the first exhaust gap 31 and / or the second exhaust gap 32. The sealing mechanism 4 is used to seal the first exhaust gap 31 and / or the second exhaust gap 32, avoiding the mutual influence of the food in the adjacent first inner cavity 21 and the heat in the second inner cavity 22 through the first exhaust gap 31 and the second exhaust gap 32, and also avoiding the mutual influence of the taste of the food in the first inner cavity 21 and the material to be dried in the second inner cavity 22 during the drying process.

[0098] In some embodiments, a first convex portion 61 is provided at the edge of the inner cavity 2;

[0099] When the inner cavity 2 is in a closed state, an exhaust gap is formed between the first convex portion 61 at the edge of the inner cavity 2 and the edge of the cabinet door 5, or a second convex portion 62 is provided at the edge of the cabinet door 5; when the inner cavity is in a closed state, an exhaust gap 3 is formed between the edge of the inner cavity and the second convex portion 62 at the edge of the cabinet door 5.

[0100] Exemplarily, referring to Figure 9 , a first convex portion 61 is provided at the edge of the inner cavity 2. When the first convex portion 61 contacts the cabinet door 5, the four sides of the cabinet door 5 and the four sides of the inner cavity 2 cannot be completely fitted when the cabinet door 5 is closed, thereby forming an exhaust gap 3.

[0101] Referring to Figure 10 , a second convex portion 62 is provided at the edge of the cabinet door 5. When the second convex portion 62 contacts the cabinet door 5, the four sides of the cabinet door 5 and the four sides of the inner cavity 2 cannot be completely fitted when the cabinet door 5 is closed, thereby forming an exhaust gap 3.

[0102] In some embodiments, the first convex portion 61 and / or the inner cavity 2 has ferromagnetic properties, so that the first convex portion 61 can be adsorbed on the inner cavity 2.

[0103] In some embodiments, the first convex portion 61 and the inner cavity 2 are integrally formed.

[0104] In some embodiments, the first convex portion 61 is independently provided on the inner cavity 2.

[0105] In some embodiments, the second convex portion 62 and / or the cabinet door 5 has ferromagnetic properties, so that the second convex portion 62 can be adsorbed on the cabinet door 5.

[0106] In some embodiments, the second convex portion 62 and the cabinet door 5 are integrally formed.

[0107] In some embodiments, the second convex portion 62 is independently provided on the cabinet door 5.

[0108] In this embodiment, the specific shapes and numbers of the first convex portion 61 and the second convex portion 62 are not limited.

[0109] In the above implementation process, by setting the first protrusion 61 or the second protrusion 62, an exhaust gap 3 is formed when the cabinet door 5 is closed. The setting process of the first protrusion 61 and the second protrusion 62 is simple, and based on this, the production efficiency of the dryer can be improved.

[0110] In some embodiments, a first recess 71 is provided at the edge of the inner cavity 2; when the inner cavity 2 is in a closed state, an exhaust gap 3 is formed between the first recess 71 at the edge of the inner cavity 2 and the edge of the cabinet door 5, or a second recess 72 is provided at the edge of the cabinet door 5, and an exhaust gap 3 is formed between the edge of the inner cavity 2 and the second recess 72 at the edge of the cabinet door 5 when the inner cavity 2 is in a closed state.

[0111] Exemplarily, referring to Figure 11 , a first recess 71 is provided at the edge of the inner cavity 2, and when the inner cavity 2 is in a closed state, an exhaust gap 3 is formed between the first recess 71 and the edge of the cabinet door 5.

[0112] Exemplarily, referring to Figure 12 , a second recess 72 is provided at the edge of the cabinet door 5, and when the inner cavity 2 is in a closed state, an exhaust gap 3 is formed between the second recess 72 and the edge of the inner cavity 2.

[0113] In some embodiments, the edge of the inner cavity 2 and / or the edge of the cabinet door 5 has ferromagnetic properties, so that the cabinet door 5 can be adsorbed on the inner cavity 2 to realize the closing of the inner cavity 2.

[0114] In this embodiment, the specific shapes and numbers of the first recess 71 and the second recess 72 are not limited.

[0115] In the above implementation process, by controlling the shapes, numbers and distributions of the first recess 71 and the second recess 72, the distribution and number of the exhaust gaps 3 can be controlled, so as to control the air circulation path of the inner cavity 2 and improve the drying effect of the inner cavity 2.

[0116] In some embodiments, a sealing mechanism 4 is provided in the first exhaust gap 31 and the second exhaust gap 32. The sealing mechanism 4 is used to partially seal the second exhaust gap 32 so that at least two sub-exhaust gaps are formed between the first exhaust gap 31 and the second exhaust gap 32; the sub-exhaust gaps 3 of the first inner cavity 21 and the sub-exhaust gaps 3 of the second inner cavity 22 are staggered.

[0117] Exemplarily, referring to Figure 13, are side views of the first exhaust gap 31 and the second exhaust gap 32 respectively; a plurality of sealing mechanisms 4 are provided on both the first exhaust gap 31 and the plurality of second exhaust gaps 32, so that a plurality of first sub-exhaust gaps 311 are formed on the first exhaust gap 31, and a plurality of second sub-exhaust gaps 321 are formed on the second exhaust gap 32.

[0118] The first sub-exhaust gap 311 of the first inner cavity 21 and the exhaust gap of the second inner cavity 22 are staggered. When the dryer is placed horizontally, the first sub-exhaust gap 311 and the second sub-exhaust gap 321 are not on the same horizontal plane.

[0119] In the above implementation process, the sub-exhaust gaps of the first inner cavity 21 and the second inner cavity 22 are staggered, which can effectively prevent the heat of the first inner cavity 21 and the second inner cavity 22 from directly entering another inner cavity through the sub-exhaust gaps, and can also prevent the materials to be dried in the first inner cavity 21 and the second inner cavity 22 from having a smell cross, while ensuring the air circulation speed of the first inner cavity 21 and the second inner cavity 22.

[0120] In some embodiments, the sealing mechanism 4 is used to completely seal the first exhaust gap 31 and / or the second exhaust gap 32.

[0121] Exemplarily, see Figure 7 , the first exhaust gap 31 is completely sealed by the sealing mechanism 4, and the second exhaust gap 32 is not sealed.

[0122] Exemplarily, see Figure 8 , the first exhaust gap 31 and the second exhaust gap 32 are completely sealed by the sealing mechanism 4.

[0123] In the above implementation process, since the first exhaust gap 31 and the second exhaust gap 32 are completely sealed, the first inner cavity 21 and the second inner cavity 22 cannot communicate with each other, realizing anti-temperature-crossing and anti-smell-crossing between the first inner cavity 21 and the second inner cavity 22.

[0124] In some embodiments, the cabinet door hinge of the first inner cavity 21 is arranged on the side away from the second inner cavity 22;

[0125] The cabinet door hinge of the second inner cavity 22 is arranged on the side away from the first inner cavity 21.

[0126] Exemplarily, see Figure 14 , the first inner cavity 21 and the second inner cavity 22 are arranged horizontally, the cabinet door hinge 81 of the first inner cavity is arranged on the left side, and the cabinet door hinge 82 of the second inner cavity is arranged on the right side.

[0127] In the above implementation process, there is usually an exhaust gap 3 at the installation location of the door hinge. The door hinge 81 of the cabinet door in the first inner chamber is arranged on the side away from the second inner chamber 22; the door hinge 82 of the cabinet door in the second inner chamber is arranged on the side away from the first inner chamber 21, which can effectively improve the anti-cross-temperature and anti-cross-odor effects of the dryer.

[0128] In some embodiments, the ratio of the area of the exhaust gap 3 to the volume of the inner chamber is: 1 mm 2 : 10416 mm 3 ~1 mm 2 : 5208 mm 3 .

[0129] The exhaust gap here refers to all the exhaust gaps formed between the area and the inner chamber.

[0130] In some embodiments, the ratio of the area of the exhaust gap 3 to the volume of the inner chamber is: 1 mm 2 : 7812.5 mm 3 .

[0131] In some embodiments, the area of the exhaust gap 3 is the perimeter of the opposite side of the inner chamber and the cabinet door 5 multiplied by the distance between the edge of the inner chamber and the cabinet door 5 when the cabinet door is in the closed state in the inner chamber.

[0132] This distance can be the maximum distance, the minimum distance, or the average distance.

[0133] In some embodiments, the sealing mechanism 4 includes: sealant and sealing strip.

[0134] Sealant refers to a sealing material that deforms with the shape of the sealing surface, does not flow easily, and has a certain adhesiveness. It is an adhesive used to fill the configuration gap to play a sealing role. It has functions such as preventing leakage, waterproofing, anti-vibration, sound insulation, and heat insulation.

[0135] A sealing strip is a product that seals something to make it not easy to open and plays roles such as shock absorption, waterproofing, sound insulation, heat insulation, dust prevention, and fixation. Sealing strips are made of various materials such as rubber, paper, metal, and plastic.
