Fig. 1 is a schematic structural diagram of a sealing device according to an embodiment of the present application. The sealing device comprises a first connecting piece 51 and a second connecting piece 52, wherein the first connecting piece 51 is provided with a first sealing surface, the second connecting piece 52 is provided with a second sealing surface, the first sealing surface of the first connecting piece 51 and the second sealing surface of the second connecting piece 52 are contacted with each other, a sealing ring 53 is arranged between the first sealing surface and the second sealing surface, a spigot structure 54 is further arranged between the first connecting piece 51 and the second connecting piece 52, and the spigot structure 54 and the sealing ring 53 form a double sealing structure between the first connecting piece 51 and the second connecting piece.
The sealing device is mainly formed by connecting a first connecting piece 51 and a second connecting piece 52, and when the sealing device is implemented, the first connecting piece 51 and the second connecting piece 52 can be any elements which need to be connected with each other and the connection part needs to be sealed, and can be flat plates, tubes and the like, and the sealing device is not limited herein. Preferably, in order to ensure a more secure connection between the first and second connection members 51 and 52, the first and second connection members 51 and 52 are respectively tubular and connected by interference fit. A seal ring 53 is arranged between the first sealing surface and the second sealing surface, and an assembly gap 55 inevitably exists between the first sealing surface and the second sealing surface, where the first connecting member 51 and the second connecting member 52 are in contact with each other, that is, the seal ring 53 is arranged in the assembly gap 55, the seal ring 53 is usually made of a sealing material such as silica gel, and the seal ring 53 is used for forming a flexible seal. The spigot structure 54 is disposed between the first connecting member 51 and the second connecting member 52 and is made of the same rigid material as the connecting member itself to form a rigid seal, so that the sealing device has a dual sealing structure of flexible seal and rigid seal, the precision requirement on the flexible seal formed by the sealing ring can be greatly reduced by adding the rigid seal formed by the spigot structure 54, and the rigid seal can better avoid performance damage to the sealing ring when the high-temperature high-pressure liquid medium or the high-temperature high-pressure gas medium enters into the assembly gap 55 of the sealing device for sealing occasions, thereby effectively ensuring sealing performance.
Specifically, the spigot structure 54 includes an inner spigot 540 and an outer spigot 541, where the outer spigot 541 and the inner spigot 540 are fastened together to form a first sealing section between the first connecting member 51 and the second connecting member 52, and the first sealing surface and the second sealing surface are in contact with each other to form a second sealing section between the first connecting member 51 and the second connecting member 52, and an included angle is formed between the first sealing section and the second sealing section. The first sealing section formed between the outer spigot 541 and the inner spigot 540 and the second sealing section formed between the first sealing surface and the second sealing surface are disposed at an included angle, where the included angle refers to an angle formed between the first sealing section and the second sealing section, and the size of the included angle may be any angle that makes the first sealing section and the second sealing section not located on the same straight line, and in a specific implementation, the included angle is preferably set to be an acute angle, so that a path of the high-temperature and high-pressure liquid medium or the high-temperature and high-pressure gas medium entering into the assembly gap 55 of the sealing device is formed to be nonlinear, and an effective blocking effect on the high-temperature and high-pressure liquid medium or the high-temperature and high-pressure gas medium is achieved.
In a specific embodiment, the first sealing section between the outer spigot 541 and the inner spigot 540 includes a vertical portion perpendicular to the second sealing section and an inclined portion extending obliquely from the vertical portion. The first sealing section between the outer spigot 541 and the inner spigot 540 includes a vertical portion and an inclined portion, and may further form a path of the high-temperature and high-pressure liquid medium or the high-temperature and high-pressure gas medium into the fitting gap 55 of the sealing device into a folded line shape with an optimal blocking effect, so as to achieve a more optimal blocking effect on the high-temperature and high-pressure liquid medium or the high-temperature and high-pressure gas medium entering the fitting gap 55 between the first sealing surface and the second sealing surface.
In an alternative embodiment, at least one recess 56 is also provided between the first sealing surface and the second sealing surface, the at least one recess 56 being located between the spigot structure 54 and the at least one sealing ring 53. The concave 56 is arranged between the first sealing surface and the second sealing surface, the concave 56 can enable the assembly gap between the first sealing surface and the second sealing surface to be an irregularly-shaped passing path, a certain resistance is formed for the assembly gap 53 between the first sealing surface and the second sealing surface after the high-temperature high-pressure liquid medium or the high-temperature high-pressure gas medium enters the assembly gap of the spigot structure 54, the high-temperature high-pressure liquid medium or the high-temperature high-pressure gas medium has the functions of reducing temperature and pressure, and the sealing performance of the sealing ring is damaged due to the erosion of the high-temperature high-pressure liquid medium or the high-temperature high-pressure gas medium to the sealing ring.
Further, the at least one seal ring 53 is plural in number, and the at least one recess 56 includes a first recess between the spigot structure 54 and the at least one seal ring 53 and a second recess between any two adjacent seal rings 53. The number of the sealing rings 53 and the number of the concave grooves 56 are respectively multiple, the plurality of sealing rings 53 can form a multiple flexible sealing structure, the plurality of concave grooves 56 can form multiple resistances on the path of the assembly gap 55 between the first sealing surface and the second sealing surface after the high-temperature high-pressure liquid medium or the high-temperature high-pressure gas medium enters the assembly gap of the spigot structure 54, the functions of cooling and reducing the pressure are realized on the high-temperature high-pressure liquid medium or the high-temperature high-pressure gas medium, and the whole sealing performance of the sealing rings and the sealing device is effectively protected.
In another alternative embodiment, the at least one recess 56 is a plurality of recesses 56, each recess 56 is annular, and the size of the plurality of recesses 56 gradually increases from the spigot structure 54 to the location of the at least one seal ring 53. The increase of the number of the recesses 56 can form more resistance to the high-temperature and high-pressure liquid medium or the high-temperature and high-pressure gas medium when reaching the position of the sealing ring 53 after entering the assembly gap between the first connecting piece 51 and the second connecting piece 52, while the size of the recesses 56 is gradually increased, and gradually increased resistance to the high-temperature and high-pressure liquid medium or the high-temperature and high-pressure gas medium entering the assembly gap between the first connecting piece 51 and the second connecting piece 52 can be formed, so that the sealing performance of the sealing device can be more effectively improved.
In one embodiment, the at least one sealing ring 53 is hollow. In this way, on the premise that the material of the sealing ring 53 does not have the deformability, the sealing ring 53 has better deformability, so that abrasion to the sealing ring 53 caused by interference fit connection of the first connecting piece 51 and the second connecting piece 52 can be avoided, and the assembly difficulty between the first connecting piece 51 and the second connecting piece 52 is reduced.
In another aspect of the embodiments of the present invention, a connection channel device including a sealing device is provided, where the connection channel device includes a first cavity, a second cavity, and a sealing device connected between the first cavity and the second cavity, where the sealing device may be a sealing device provided in any embodiment of the present application. Specifically, the first connecting piece in the sealing device is a first connecting pipe communicated with the first cavity, and the second connecting piece is a second connecting pipe communicated with the second cavity.
The first connecting pipe is arranged on the outer surface of the second connecting pipe in a surrounding mode, and the spigot structure is formed between the end portion of the second connecting pipe and the inner surface of the first connecting pipe.
Referring to fig. 2 and 3, in another aspect of the present invention, a garment steamer is provided, and the garment steamer includes the connection channel device provided in any one of the above embodiments. The connection channel device can be specifically a water level adjusting mechanism in the garment steamer, and the water level adjusting mechanism comprises a water tank 10 and a steam generating device 30. The water tank 10 includes a tank inner chamber 12 and a first intake pipe 11 communicating with the tank inner chamber 12. The steam generating device 30 includes a heating water chamber 31, a heater 32 located in the heating water chamber 31, and a second air inlet pipe 33 communicating with the heating water chamber 31. Wherein the first intake pipe 11 and the second intake pipe 33 are connected to form an air pressure passage 35. The water tank 10 and the steam generating device 30 are communicated through an air pressure channel 35.
Further, the water tank 10 further comprises a first water inlet pipe 13 communicating with the water tank inner chamber 12, and the steam generating device 30 further comprises a second water inlet pipe 34 communicating with the heating water chamber 31. Wherein the first inlet pipe 13 and the second inlet pipe 34 are connected to form an inlet channel 36. The water tank 10 and the steam generating device 30 are communicated through a water inlet channel 36. The air pressure passage 35 is higher than the water inlet passage 36.
In this embodiment, taking the air pressure channel 35 in the water level adjusting mechanism as an example, the first cavity of the connecting channel device refers to the water tank inner cavity 12 of the water tank 10, the second cavity refers to the heating water cavity 31 of the steam generating device 30, the first air inlet pipe 11 is a first connecting pipe, and the second air inlet pipe 33 is a second connecting pipe. During operation of the water level adjusting mechanism, a large amount of high-pressure steam is generated in the heating water cavity 31 of the steam generating device 30 and flows into the water tank cavity 12 of the water tank 10 through the air pressure channel 35, so that the air pressure in the water tank cavity 12 tends to be equal to the air pressure in the heating water cavity 31, and meanwhile, water in the water tank cavity 12 supplements the steam generating device 30 through the water inlet channel 36, so that the water level in the steam generating device 30 is equal to the water level in the water tank 10. When the air pressure passage 35 is formed by the first air intake pipe 11 and the second air intake pipe 33, it may include both cases where the outer circumferential surface of the first air intake pipe 11 and the inner circumferential surface of the second air intake pipe 33 are in contact with each other, and where the inner circumferential surface of the first air intake pipe 11 and the outer circumferential surface of the second air intake pipe 33 are in contact with each other.
In this embodiment, since the air pressure passage 35 is mainly used to enable high pressure steam in the steam generating device 30 to flow into the water tank 10 therethrough, it is preferable to set the size of the second air intake pipe 33 smaller than the size of the first air intake pipe 11, the air pressure passage 35 is formed by connecting the outer circumferential surface of the second air intake pipe 33 with the inner circumferential surface of the first air intake pipe 11, that is, the air pressure passage 35 is formed by looping the first air intake pipe 11 around the outer circumferential surface of the second air intake pipe 33, at this time, the inner circumferential surface of the first air intake pipe 11 and the outer circumferential surface of the second air intake pipe 33 are in contact with each other, so that the fitting gap 55 between the first air intake pipe 11 and the second air intake pipe 33 is located at one end inside the water tank 10, and on the premise that the fitting gap 55 inevitably exists between the first air intake pipe 11 and the second air intake pipe 33, the impact force on the interconnection between the first air intake pipe 11 and the second air intake pipe 33 when the high pressure steam flows from the steam generating device 30 to the water tank 10 is reduced.
The spigot structure 54 is formed at one end of the fitting gap 55 between the first intake pipe 11 and the second intake pipe 33 at the inside of the water level adjustment mechanism, i.e., the spigot structure 54 is formed at one end of the fitting gap 55 between the first intake pipe 11 and the second intake pipe 33 communicating with the inside of the air pressure passage 35. It will be appreciated that the end of the fitting gap 55 between the first air inlet pipe 11 and the second air inlet pipe 33 located inside the water level adjustment mechanism is specifically determined according to the relative positions of the first air inlet pipe 11 and the second air inlet pipe 33, when the first air inlet pipe 11 is disposed around the periphery of the second air inlet pipe 33, the end of the fitting gap 55 between the first air inlet pipe 11 and the second air inlet pipe 33 located inside the water level adjustment mechanism is the end of the air pressure passage 35 near the water tank 10, whereas when the second air inlet pipe 33 is disposed around the periphery of the first air inlet pipe 11, the end of the fitting gap 55 between the first air inlet pipe 11 and the second air inlet pipe 33 located inside the water level adjustment mechanism is the end of the air pressure passage 35 near the steam generating device 30. In the present embodiment, the first air inlet pipe 11 is annularly disposed on the outer circumferential surface of the second air inlet pipe 33 to form the air pressure passage 35 such that an end of the fitting gap 55 between the first air inlet pipe 11 and the second air inlet pipe 33 located inside the water level adjusting mechanism is an end close to the water tank 10, and the spigot structure 54 is correspondingly formed at an end of the air pressure passage 35 close to the water tank 10. Specifically, the inner spigot 540 is formed at the end of the second intake pipe 33, the outer spigot 541 is formed on the inner circumferential surface of the first intake pipe 11, and when the first intake pipe 11 and the second intake pipe 33 are connected, the outer spigot 541 and the inner spigot 540 are engaged with each other and the outer spigot is wrapped around the outer periphery of the inner spigot. The spigot structure 54 corresponds to a rigid sealing structure added between the circumferential surfaces of the first intake pipe 11 and the second intake pipe 33 that are in contact with each other, so that the fitting gap 55 between the first intake pipe 11 and the second intake pipe 33 into which high-pressure steam inside the water level adjustment mechanism enters can be further reduced, and the impact force of the high-pressure steam on the junction of the first intake pipe 11 and the second intake pipe 33 can be reduced.
Further, the air pressure passage 35 further includes at least one seal ring 53 provided between circumferential surfaces of the first air intake pipe 11 and the second air intake pipe 33 that are in contact with each other. The sealing ring 53 is provided between the circumferential surfaces of the first intake pipe 11 and the second intake pipe 33 that are in contact with each other, and can increase the sealing performance of the air pressure passage 35. The sealing ring 53 is hollow, so that the sealing ring 53 has better deformability on the premise that the material of the sealing ring 53 does not have deformability, thereby avoiding abrasion to the sealing ring 53 caused by tight fit connection of the first air inlet pipe 11 and the second air inlet pipe 33 and reducing assembly difficulty between the first air inlet pipe 11 and the second air inlet pipe 33.
Further, the air pressure channel 35 further includes at least one recess 56 disposed between the circumferential surfaces of the first air inlet pipe 11 and the second air inlet pipe 33, and the at least one recess 56 is located between one end close to the spigot structure 54 and the at least one sealing ring 53. A recess 56 is arranged between the circumferential surfaces of the first air inlet pipe 11 and the second air inlet pipe 33, which are in contact with each other, and the recess 56 forms a certain resistance to the high-pressure steam reaching the sealing ring 53 after entering the assembly gap 55 between the first air inlet pipe 11 and the second air inlet pipe 33, so that the erosion of the sealing ring 53 by the high-pressure steam is reduced, and the sealing performance is damaged.
Further, the number of the at least one recess 56 is plural, each recess 56 is in a ring shape, the plurality of recesses 56 are distributed between one end of the air pressure channel 35 close to the spigot structure 54 and the at least one sealing ring 53 along the radial direction of the air pressure channel 35, and the size of the plurality of recesses 56 gradually increases from one end of the air pressure channel 35 close to the spigot structure 54 to the position of the at least one sealing ring 53. The increasing number of the recesses 56 can form more resistance to the high pressure steam entering the fitting gap 55 between the first air inlet pipe 11 and the second air inlet pipe 33 when reaching the position where the sealing ring 53 is located, while the increasing size of the recesses 56 can form gradually increasing resistance to the high pressure steam entering the fitting gap 55 between the first air inlet pipe 11 and the second air inlet pipe 33, so that the tightness of the air pressure channel 35 can be maintained more effectively.
