Description

Technical Field

[0001] This utility model relates to a sealing sleeve and a coffee machine using the sealing sleeve. Background Technology

[0002] In existing technologies, sealing sleeves are widely used in pipe connections, especially in high-temperature environments. Traditional sealing sleeves typically consist of an outer shell and a sealing ring, which is installed between the pipe and the outer shell to prevent leakage at the pipe connection. However, with prolonged use, especially in high-temperature environments, the sealing ring often ages and shrinks due to the effects of high temperatures, gradually weakening its sealing effect. This can eventually lead to gaps between the sealing ring and the outer shell, resulting in leakage problems. Utility Model Content

[0003] The primary objective of this invention is to provide a sealing sleeve that can maintain its sealing function even after the sealing ring has aged and shrunk.

[0004] The second objective of this invention is to provide a coffee machine that prevents water leakage.

[0005] The primary objective of this invention is achieved as follows:

[0006] A sealing sleeve includes a high-temperature resistant rubber sleeve and a shell. The inner wall of the high-temperature resistant rubber sleeve is provided with a first sealing ring at intervals near its front port. The inner cavity of the first sealing ring forms a first pipe clamping area.

[0007] The high-temperature resistant rubber sleeve has a second sealing ring spaced apart near its rear port position on the inner wall of the sleeve, and the inner cavity of the second sealing ring forms a second pipe clamping area.

[0008] The high-temperature resistant rubber sleeve forms the pipe connection area in the region between the first and second sealing rings.

[0009] The first sealing ring, the second sealing ring, and the high-temperature resistant rubber sleeve are integrally molded;

[0010] The outer shell is fitted over a high-temperature resistant rubber sleeve.

[0011] The tight fit between the first and second sealing rings ensures a good seal in the pipe connection area, effectively preventing liquid or gas leakage, ensuring the stability and safety of the pipe connection in the connection area, and avoiding water leakage.

[0012] The outer shell is placed over the high-temperature resistant rubber sleeve, which helps to limit the deformation of the sealing sleeve. This design enhances the stability of the sealing sleeve under high temperature and high pressure environments, prevents the rubber sleeve from undergoing excessive deformation during long-term use, and thus ensures a long-lasting and stable sealing effect.

[0013] As the first and second sealing rings age and shrink due to high temperatures and prolonged use, the high-temperature resistant rubber sleeve automatically shrinks to compensate for the changes in the first and second sealing rings, ensuring that the sealing effect is not affected and greatly improving the durability and service life of the equipment.

[0014] Because the first and second sealing rings are integrally molded with the high-temperature resistant rubber sleeve, and the outer shell provides additional support, the sealing sleeve can withstand higher pressure and temperature in actual use, ensuring good sealing performance even in harsh environments and effectively preventing leakage and equipment failure.

[0015] The primary objective of this utility model can also be achieved by the following technical measures:

[0016] Furthermore, the diameters of both the first and second pipe clamping areas are smaller than the diameter of the pipe docking area.

[0017] By designing the diameters of the first and second pipe clamping areas to be smaller than the diameter of the pipe connection area, a more precise pipe clamping effect can be achieved, and the force on the pipe in the clamping area is more uniform, thereby ensuring the firmness and sealing of the pipe connection.

[0018] The small-diameter clamping area can apply greater clamping force to the pipe, ensuring the pipe is stably positioned within the sealing sleeve. As the outer wall of the high-temperature resistant rubber sleeve shrinks, the contact between the sealing ring and the pipe becomes tighter, enhancing the seal and reducing the risk of leakage due to pipe loosening.

[0019] Furthermore, the outer shell is a rigid outer shell.

[0020] Using a rigid outer shell improves the overall durability and pressure resistance of the sealing sleeve. The rigid shell effectively prevents damage to the sealing sleeve from external forces, ensuring the stability of the sealing system during long-term use, especially in harsh environments.

[0021] The use of a rigid outer shell gives the sealing sleeve higher rigidity, preventing changes in the shape of the sealing sleeve due to the external environment or external pressure, and maintaining the long-term effectiveness of the sealing function.

[0022] The rigid outer shell protects the high-temperature resistant sleeve and sealing ring, preventing them from being damaged or deformed under high temperatures or external forces, thus ensuring that the sealing effect remains unaffected over a long period. The rigid outer shell also helps to effectively isolate the sealing sleeve from the direct influence of the external environment, improving system safety.

[0023] The high temperature resistance and corrosion resistance of the rigid outer shell make the sealing sleeve suitable for a variety of industrial environments. Especially under harsh conditions such as high temperature and high pressure, it can maintain excellent sealing performance, enhancing the applicability and versatility of the product.

[0024] The second objective of this utility model is achieved as follows:

[0025] A coffee machine includes a water tank, a water pump, a heating boiler, and a steam valve. The inlet of the water pump is connected to the outlet of the water tank, the outlet of the water pump is connected to the inlet of the heating boiler, and the steam outlet of the heating boiler is connected to the steam inlet of the steam valve.

[0026] The water pump outlet is provided with a first pipe, which passes through the first pipe clamping area of ​​the sealing sleeve and enters the pipe docking area, and the first sealing ring is tightly attached to the outer wall of the first pipe.

[0027] The heating boiler is provided with a second pipe at its water inlet. The second pipe passes through the second pipe clamping area of ​​the sealing sleeve and enters the pipe docking area. The second sealing ring is tightly attached to the outer wall of the second pipe, so that the first pipe and the second pipe are connected through the sealing sleeve. The outer shell is placed on the outside of the high-temperature resistant rubber sleeve.

[0028] By employing a sealed sleeve design, the pipe connection between the water pump outlet and the heating boiler inlet is ensured to be secure and sealed. The first and second pipes are tightly connected through the sealed sleeve, reducing the risk of leakage at the pipe connection and improving the fluid transfer efficiency between the water pump and the heating boiler.

[0029] The first and second sealing rings in the sealing sleeve are in close contact with the outer walls of the first and second pipes, respectively, effectively preventing water leakage between the water pump and the heating boiler. Meanwhile, the use of high-temperature resistant rubber sleeve material ensures that the sealing system can withstand prolonged operation in high-temperature environments, maintaining its sealing performance and reliability, and extending the lifespan of the coffee machine.

[0030] In this design, the integrated sealing sleeve structure simplifies the connection process between the water pump and the heating boiler, avoids complex sealing component configurations, and simplifies production and installation processes. Due to the sealing sleeve design, the installation of pipe connections is more convenient and faster, and effectively reduces human error during operation.

[0031] By using a high-temperature resistant, rigid outer shell for the sealing sleeve, not only is the structural stability enhanced, but the system's adaptability to external pressure, temperature, and corrosion is also increased, improving the overall safety and reliability of the coffee machine. The rigid outer shell also prevents leaks or other safety hazards under high temperature and pressure.

[0032] The design of the sealing sleeve ensures that the sealing ring will not fail due to aging or shrinkage, even under prolonged high-temperature use. The outer wall of the high-temperature resistant sleeve can automatically shrink to compensate for the aging of the sealing ring, ensuring effective sealing performance even after long-term operation, reducing maintenance costs and the need for frequent component replacement.

[0033] The beneficial effects of this utility model are as follows:

[0034] This invention ensures a good sealing effect in the pipe connection area through the tight cooperation of the first and second sealing rings. This effectively prevents liquid or gas leakage, ensures the stability and safety of the pipe connection in the pipe connection area, and avoids water leakage.

[0035] In this invention, the outer shell is placed outside the high-temperature resistant rubber sleeve, which helps to limit the deformation of the sealing sleeve. This design enhances the stability of the sealing sleeve under high temperature and high pressure environments, prevents the rubber sleeve from undergoing excessive deformation during long-term use, and thus ensures a long-lasting and stable sealing effect.

[0036] In this invention, as the first and second sealing rings age and shrink due to high temperature and prolonged use, the high-temperature resistant rubber sleeve automatically shrinks to compensate for the changes in the first and second sealing rings, ensuring that the sealing effect is not affected, and greatly improving the durability and service life of the equipment.

[0037] In this invention, the first sealing ring, the second sealing ring, and the high-temperature resistant rubber sleeve are integrally formed, and the outer shell provides additional support. The sealing sleeve can withstand higher pressure and temperature in actual use, ensuring good sealing performance even in harsh environments and effectively preventing leakage and equipment failure.

[0038] This invention employs a sealed sleeve design to ensure a stable and sealed pipe connection between the water pump outlet and the heating boiler inlet. The first and second pipes are tightly connected through the sealed sleeve, reducing the risk of leakage at the pipe connection and improving the fluid transmission efficiency between the water pump and the heating boiler.

[0039] Figure 1 This is a schematic diagram illustrating the working principle of a coffee machine.

[0040] Figure 2 for Figure 1 Enlarged view of part A. Detailed Implementation

[0041] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0042] Implementation examples, in conjunction with Figures 1 to 2 As shown, a sealing sleeve includes a high-temperature resistant rubber sleeve 1 and a shell 2. The inner wall of the high-temperature resistant rubber sleeve 1 is provided with a first sealing ring 3 at intervals near its front port. The inner cavity of the first sealing ring 3 forms a first pipe clamping area 31.

[0043] The high-temperature resistant rubber sleeve 1 has a second sealing ring 4 spaced apart near its rear port position on the inner wall of the sleeve 1, and the inner cavity of the second sealing ring 4 forms a second pipe clamping area 41.

[0044] The high-temperature resistant rubber sleeve 1 forms the pipe connection area 5 in the area between the first sealing ring 3 and the second sealing ring 4.

[0045] The first sealing ring 3, the second sealing ring 4, and the high-temperature resistant rubber sleeve 1 are integrally formed;

[0046] The outer shell 2 is fitted over the high-temperature resistant rubber sleeve 1.

[0047] Furthermore, the diameters of the first pipe clamping region 31 and the second pipe clamping region 41 are both smaller than the diameter of the pipe docking region 5.

[0048] Furthermore, the outer shell 2 is a rigid outer shell.

[0049] A coffee machine includes a water tank 6, a water pump 7, a heating boiler 8, and a steam valve 9. The inlet of the water pump 7 is connected to the outlet of the water tank 6, the outlet of the water pump 7 is connected to the inlet of the heating boiler 8, and the steam outlet of the heating boiler 8 is connected to the steam inlet of the steam valve 9.

[0050] The outlet of the water pump 7 is provided with a first pipe 100. The first pipe 100 passes through the first pipe clamping area 31 of the sealing sleeve and enters the pipe docking area 5. The first sealing ring 3 is tightly attached to the outer wall of the first pipe 100.

[0051] The water inlet of the heating boiler 8 is provided with a second pipe 200. The second pipe 200 passes through the second pipe clamping area 41 of the sealing sleeve and enters the pipe docking area 5. The second sealing ring 4 is tightly attached to the outer wall of the second pipe 200, so that the first pipe 100 and the second pipe 200 are connected through the sealing sleeve. The outer shell 2 is placed outside the high temperature resistant rubber sleeve 1.

[0052] The first pipe 100 and the second pipe 200 are sealed by a sealing sleeve:

[0053] First, the first pipe 100 is inserted into the first pipe clamping area 31 of the sealing sleeve, and the second pipe 200 is inserted into the second pipe clamping area 41. The first sealing ring 3 and the second sealing ring 4 on the inner wall of the high-temperature resistant rubber sleeve 1 of the sealing sleeve are respectively tightly attached to the outer walls of the first pipe 100 and the second pipe 200. This design ensures that the two pipes are in close contact with the sealing sleeve, forming an effective seal.

[0054] The first pipe 100 and the second pipe 200 are connected through the pipe docking area 5 of the sealed sleeve. The first sealing ring 3, the second sealing ring 4 and the high-temperature resistant rubber sleeve 1 work together to ensure the sealing of the pipe docking area 5 and effectively prevent liquid or gas leakage.

[0055] Under normal circumstances, the first pipe 100 and the second pipe 200 are sealed by the sealing sleeve.

[0056] The first sealing ring 3 clamps the first pipe 100 in the first pipe clamping area 31 of the sealing sleeve. The inner cavity of the first sealing ring 3 is tightly fitted to the outer wall of the first pipe 100, forming a uniform and lasting sealing pressure. This sealing pressure ensures that the first pipe 100 and the sealing sleeve have a tight contact, preventing liquid or gas leakage.

[0057] The second sealing ring 4 clamps the second pipe 200 in the second pipe clamping area 41 of the sealing sleeve. The inner cavity of the second sealing ring 4 fits tightly against the outer wall of the second pipe 200, providing uniform sealing pressure and ensuring the sealing effect between the second pipe 200 and the sealing sleeve. The second sealing ring 4 works in conjunction with the first sealing ring 3 to further enhance the sealing performance.

[0058] The outer shell 2 is placed outside the high-temperature resistant rubber sleeve 1, which plays a role in limiting the deformation of the sealing sleeve. The rigid design of the outer shell 2 prevents the rubber sleeve from being excessively deformed during long-term use or in high-temperature environments, maintaining the overall stability and structural strength of the sealing sleeve. The outer shell 2 provides additional protection to ensure that the shape and structure of the sealing sleeve will not change significantly under high pressure and high temperature conditions, thereby maintaining the sealing effect at the pipe connection.

[0059] The first sealing ring 3, the second sealing ring 4, and the high-temperature resistant rubber sleeve 1 work together to ensure the sealing of the pipe connection area 5. When the first pipe 100 and the second pipe 200 are connected through the sealing sleeve, the tight contact between the first sealing ring 3 and the outer wall of the first pipe 100, and the tight contact between the second sealing ring 4 and the outer wall of the second pipe 200, ensures that there are no gaps between the sealing sleeve and the first pipe 100 and the second pipe 200, preventing moisture or gas leakage.

[0060] The principle behind why the sealing sleeve can still seal the first pipe 100 and the second pipe 200 even after aging:

[0061] The first sealing ring 3 and the second sealing ring 4 may age and shrink due to high temperature and long-term use. After the first sealing ring 3 shrinks, it will still clamp the first pipe 100 in the first pipe clamping area 31 of the sealing sleeve. After the second sealing ring 4 shrinks, it will still clamp the second pipe 200 in the second pipe clamping area 41 of the sealing sleeve. At the same time, the outer wall of the high-temperature resistant rubber sleeve 1 will automatically shrink with the changes of the first sealing ring 3 and the second sealing ring 4 to compensate for the shrinkage of the first sealing ring 3 and the second sealing ring 4, ensuring the sealing of the pipe docking area 5, and ensuring that there are no gaps between the sealing sleeve and the first pipe 100 and the second pipe 200, preventing moisture or gas leakage.

[0062] Meanwhile, the outer shell 2 of the sealing sleeve provides structural support, restricts the deformation of the high-temperature resistant rubber sleeve 1, ensures that the sealing performance of the pipe connection is not affected, and prevents leakage.
