Description

Technical Field

[0001] The utility model relates to the technical field of coffee machines, in particular to a steam sealing device and a coffee machine. Background Art

[0002] At present, some coffee machines on the market are usually used in conjunction with brewers. After the coffee machine grinds the coffee powder, the coffee powder will fall from the powder outlet to the brewer below for brewing. However, the steam generated during the brewing process will enter the powder outlet, causing the residual coffee powder to solidify at the powder outlet, resulting in blockage of the powder outlet, which not only affects the normal operation of the coffee machine, but also may affect the taste and quality of the coffee. Therefore, in order to prevent steam from entering the powder outlet, the coffee machine usually needs to be installed with a steam sealing device. At present, common steam sealing devices usually use electrical components such as motors and electromagnets to control the baffle to block and seal the powder outlet. These traditional steam sealing devices have some problems: first, because the powder outlet of the brewer will generate steam for a long time, the accumulation of water vapor will affect the performance of the electrical components, such as causing the motor to rust or damage, and causing the magnetic force of the electromagnet to decrease or fail. In addition, the high temperature of the steam will also affect the performance of the electrical components. Therefore, when designing the steam sealing device, it is necessary to keep the electrical components away from the powder outlet or waterproof the electrical components, which undoubtedly increases the structural complexity and production cost.

[0028] The utility model injects a medium into the inner cavity 5 of the driving component 41 to drive the movable member 413 to drive the baffle 42 to slide to the open position. In addition, the baffle 42 is driven to slide to the steam sealing position by the reset component 414. This arrangement can realize the closing and opening functions of the steam sealing device 4 without the need for electrical components, which not only avoids the performance problems caused by steam to electrical components in some occasions for shielding steam, but also simplifies the structure and improves the durability and reliability of the device.

[0029] Specifically, the medium used in this embodiment can be liquid or gas. The utility model injects the medium into the inner cavity 5 of the driving component 41 to drive the moving part 413 to drive the baffle 42 to slide to the open position. When the steam sealing port needs to be closed, the baffle 42 is driven to slide to the steam sealing position through the action of the reset component 414 to achieve a shielding effect. This setting cleverly utilizes the pressure of the medium and the elastic reset function of the reset component 414, avoiding the problem that steam and temperature affect the performance of electrical components on the steam sealing device 4 in some occasions with steam and high temperature; further, since electrical components such as motors or electromagnets are not required, the risk of failure of electrical components is reduced, the overall structure of the device is simplified, and the production and maintenance costs are reduced; further, this mechanical drive and reset method improves the durability and reliability of the device, ensures that the steam sealing device 4 can work stably and efficiently during long-term use, and further improves the user experience.

[0031] In the utility model, an injection end 4112 and an injection cavity 4113 are arranged on one side of the shell 1, and the force-bearing end 4134 corresponds to the injection cavity 4113, that is, the medium completely acts on the force-bearing end 4134 after entering the injection cavity 4113. This arrangement ensures that the medium can be easily injected into the inner cavity 5 of the driving component 41, thereby effectively driving the moving part 413 to work; further, the force-bearing end 4134 is sealed and connected to the side wall of the inner cavity 5, thereby ensuring the pressure transmission efficiency of the medium in the inner cavity 5, and the driving effect will not be weakened due to leakage. This arrangement not only ensures the smooth movement of the moving part 413 under the action of the medium pressure, but also transmits this movement to the baffle 42 through the rod body 4131, thereby realizing the smooth sliding of the baffle 42; further, the sealed connection between the force-bearing end 4134 and the side wall of the inner cavity 5 effectively prevents leakage of the medium, improves the working efficiency and safety of the device, and further enhances the durability and reliability of the steam sealing device.

[0033] In the utility model, the reset component 414 is arranged in the inner cavity 5 and presses on one side of the force-bearing end 4134, ensuring that the movable part 413 can be quickly reset after the medium pressure disappears. This setting utilizes the elastic force of the reset component 414, so that the baffle 42 can reliably return to the steam-sealing position in the absence of medium pressure, avoiding the problem of the baffle 42 being unable to be reset due to insufficient or disappearing medium pressure; further, the setting of the reset component 414 not only simplifies the structure of the device and avoids the complexity of electrical control, but also improves the stability and reliability of the steam-sealing device in high temperature and humid environments; further, this mechanical reset method reduces the use of electrical components, reduces the risk of failure and maintenance costs, and ensures the stable and efficient operation of the steam-sealing device in long-term use.
