DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] The following further details the specific embodiments of the present utility model in conjunction with the drawings, so that the technical solutions of the present utility model are easier to understand and master.
[0017] In this embodiment, it should be understood that the orientation or positional relationships indicated by terms such as "middle", "upper", "lower", "top", "right side", "left end", "above", "back", "middle", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present invention.
[0018] In addition, in this specific embodiment, if there is no special description of the connection or fixing method between components, the connection or fixing method can be bolt fixing, nail pin fixing, or pin shaft connection, etc., which are commonly used in the prior art. Therefore, it will not be elaborated in this embodiment.
[0019] The present utility model provides a steam valve structure for a coffee machine, as Figure 1-2As shown in the figure, it includes a valve body 1, a steam inlet joint 2, a steam outlet joint 3, an adjustment knob 4 and a sealing column 5. A sealing cavity 11 is formed inside the valve body 1. The steam inlet joint 2 and the steam outlet joint 3 are both arranged on the valve body 1 and communicate with the valve body 1. The sealing column 5 is arranged inside the sealing cavity 11, and the end of the sealing column 5 is fixedly connected to the adjustment knob 4. A tapered channel 6 is arranged between the sealing cavity 11 and the steam inlet joint 2. One end of the sealing column 5 is provided with a tapered abutting head 51 corresponding to the tapered channel 6. A first sealing ring 52 is sleeved on the tapered abutting head 51. Internal threads 12 are formed inside the sealing cavity 11, and external threads 53 corresponding to the internal threads 12 are arranged on the sealing column 5. By rotating the adjustment knob 4, the sealing column 5 feeds into the inside of the sealing cavity 11 by means of the external threads 53, so that the tapered abutting head 51 of the sealing column 5 abuts against the tapered channel 6 to form an inclined surface seal, and a secondary seal is also formed between the first sealing ring 52 and the tapered channel 6, thereby realizing the on-off of steam, and the sealing performance is better, thus prolonging the service life of the coffee machine.
[0020] Preferably, the steam inlet joint 2 and the valve body 1 are on the same axis; the steam outlet joint 3 is perpendicular to the axis of the valve body 1, so that after the steam enters the sealing cavity 11 from the steam inlet joint 2, it makes a single turn and then enters the steam outlet joint 3.
[0021] Preferably, a groove 54 is formed on the sealing column 5 between the tapered abutting head 51 and the external threads 53, and a plurality of second sealing rings 55 are sleeved in the groove 54, so as to form a movable sealing connection between the second sealing rings 55 and the sealing cavity 11, thereby preventing steam from leaking between the sealing column 5 and the sealing cavity 11.
[0022] Preferably, the cross-section of the valve body 1 is polygonally arranged, which is convenient for clamping and fixing the valve body 1 when installing the steam inlet pipe and the steam outlet pipe.
[0023] Preferably, the connection between the steam outlet joint 3 and the valve body 1 is a sealed connection.
[0024] Preferably, the steam inlet joint 2 and the valve body 1 are integrally formed.
[0025] Preferably, the number of threads of the external threads 53 is equal to or greater than 2 starts, which is convenient for obtaining a larger stroke under the same opening and closing angle.
[0026] Preferably, a limit pin hole 13 is also formed on the valve body 1. When the valve body 1 is sealed, a pin is inserted into the limit pin hole 13 so that the valve body 1 always maintains a sealed state.
[0027] The technical effects of the present utility model are mainly reflected as follows: By rotating the adjustment knob, the sealing column feeds into the interior of the sealing cavity by means of external threads, so that the conical abutting head of the sealing column abuts against the conical channel to form an inclined plane seal. Additionally, a secondary seal is formed by the first sealing ring and the conical channel, thereby realizing the on-off of steam conduction and having better sealing performance, thus prolonging the service life of the coffee machine.
[0028] Of course, the above are only typical examples of the present utility model. In addition, the present utility model can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present utility model.
