[0019] Embodiment 1

[0020] like Figure 1 As shown, the utility model provides a mechanical filling valve for filling fruit beverage, including a filling valve body 10 and a sleeve 13. The upper end of the filling valve body 10 is sleeved with a lower valve seat 4, and the top of the lower valve seat 4 is installed with an upper valve seat 2. The lower valve seat 4 and the upper valve seat 2 are installed on a bracket 3. A feed port 1 is provided on the upper valve seat 2, and a filling valve cavity 5 is provided in the lower valve seat 4. The feed port 1 and the filling valve cavity 5 are communicated. A flow channel is provided in the filling valve body 10, and the filling valve cavity 5 and the flow channel form a channel for liquid flow. An outer sleeve 8 is sleeved on the lower end of the lower valve seat 4, and a spring 9 is sleeved on the outer ring of the filling valve body 10. The filling valve body 10 and the spring 9 are located in the outer sleeve 8. When an upward force is applied to the filling valve body 10, the spring 9 is compressed by force. When the force applied to the filling valve body 10 is released, the filling valve body 10 slides downward by the elasticity of the spring 9.

[0021] A central air return pipe 11 is installed on the filling valve body 10, and an air return channel 12 is reserved on the central air return pipe 11. The lower end of the filling valve body 10 is sleeved on the sleeve 13, and the outer wall of the sleeve 13 and the inner wall of the filling valve body 10 are sealed. The central air return pipe 11 runs through the filling valve body 10 and the sleeve 13, and the three are coaxial. The central air return pipe 11 is located below the filling valve cavity 5. A connecting pipe 6 is installed on one side of the lower valve seat 4. An air outlet channel 7 is reserved in the connecting pipe 6. One end of the connecting pipe 6 is connected to the central air return pipe 11, and the other end of the connecting pipe 6 is located outside the valve seat, so as to better discharge the air in the beverage bottle 18. Figure 3 As shown, an anti-blocking body 16 is installed at the bottom end of the central air return pipe 11, and a plurality of air return holes 15 are opened around the anti-blocking body 16. The air return holes 15 are communicated with the air return channel 12. When the juice is filled, the air in the beverage bottle 18 is discharged through the air return holes 15 and the air return channel 12. When filling, the lower end of the central air return pipe 11 extends down to the bottle mouth of the beverage bottle 18, so that the air return holes 15 are located in the beverage bottle 18. The lower end of the sleeve 13 is sleeved on the anti-blocking body 16, and the outer wall of the anti-blocking body 16 and the inner wall of the sleeve 13 are sealed. During filling, the lower end of the sleeve 13 extends downward into the mouth of the beverage bottle 18, and the top of the mouth of the beverage bottle 18 and the outer wall of the lower end of the filling valve body 10 are sealed. A liquid outlet 19 is reserved around the lower end of the sleeve 13. During filling, the liquid outlet 19 is located in the beverage bottle 18. A sealing ring 21 is sleeved on the outer ring of the upper end of the anti-blocking body 16, an inner step surface 17 is provided on the inner wall of the sleeve 13, and an outer step surface 20 is provided on the outer wall of the sealing ring 21. Figure 2 As shown, when the filling valve is in a closed state, the inner step surface 17 and the outer step surface 21 fit together to form a seal between the sleeve 13 and the anti-blocking body 16, thereby preventing the juice from being filled.

[0022] During the filling process, as the liquid level in the beverage bottle 18 rises, the fruit particles in the beverage bottle 18 will accumulate at the air return hole 15. Therefore, in this embodiment, a filter 14 is installed in the air return hole 15 to prevent the fruit particles from entering the air return hole 15, thereby avoiding blockage of the air return hole 15.

[0023] At the beginning of filling, under the action of an external cam mechanism (not shown in the figure, belonging to the prior art, and no longer described here), the mouth of the beverage bottle 18 pushes the filling valve body 10 upward to compress the spring 9. At this time, the filling valve body 10 switches from a closed state to an open state, and the sleeve 13 slides upward relative to the anti-blocking body 16 together with the filling valve body 10. At this time, the sleeve 13 is located above the return air hole 15, the return air hole 15 is in a ventilated state, and the liquid outlet 19 is connected to the flow channel, thereby achieving juice filling and normal exhaust of the return air hole 15; after the filling of the beverage bottle 18 is completed, the beverage bottle 18 is under the action of the external cam mechanism The filling valve body 10 is switched from the open state to the closed state. Under the thrust of the spring 9, the sleeve 13 slides downward relative to the anti-blocking body 16 together with the filling valve body 10. The inner step surface 17 and the outer step surface 21 fit together to form a seal between the sleeve 13 and the anti-blocking body 16. The liquid outlet 19 is closed, thereby preventing the juice from being filled. In the process of the sleeve 13 sliding down, the fruit particles remaining on the filter screen 14 are scraped off by the sleeve 13 to avoid the residual fruit particles on the filter screen 14 affecting the air return effect in the beverage bottle 18 during the next filling. Figure 2 As shown, when the filling valve is in a closed state, the position of the air return hole 15 is completely blocked by the sleeve 13.

[0024] Embodiment 2

[0025] On the basis of the above-mentioned embodiment 1, a plurality of flow channels are reserved in the circumferential direction of the filling valve body 10. During the filling process, the speed of the liquid is slowed down through the plurality of flow channels, thereby reducing the foam in the beverage bottle 18. At the same time, for the filling of beverages containing fruit particles, the fruit particles are first filled into the beverage bottle 18, and then the filling valve is used to fill the liquid, thereby achieving the purpose of reducing the foam in the beverage bottle 18.

[0026] Furthermore, if Figure 3 As shown, during filling, the lower end of the sleeve 13 extends downward into the mouth of the beverage bottle 18, and the top of the mouth of the beverage bottle 18 and the outer wall of the lower end of the filling valve body 10 are sealed to prevent foam from overflowing from the mouth of the beverage bottle 18.

[0027] The other structures and principles of this embodiment are the same as those of the first embodiment.
