Description

Technical Field

[0001] This utility model relates to a sealing connection structure for the tea bowl of a tea tasting machine. Background Technology

[0002] The sealing connection between the body of existing tea tasting machines and the bottom of the teacup is mostly achieved by the weight of the teacup pressing against the sealing ring on the machine body. This sealing connection relies on the shape of the teacup to fit tightly against the sealing ring. However, when applied to teacups made of glass or ceramic, the inherent shrinkage rate differences during the firing process and processing limitations result in significant dimensional tolerances. Existing sealing methods relying on gravity to press the sealing ring are insufficient to effectively compensate for these tolerance fluctuations, easily leading to misalignment, local gaps, or insufficient sealing force, resulting in tea leakage during brewing. Furthermore, the brittleness of glass and ceramic also limits the possibility of compensating for these tolerances by forcibly deforming the teacup.

[0003] Therefore, overcoming the aforementioned shortcomings has become an important issue that urgently needs to be addressed by those skilled in the art. Utility Model Content

[0004] This utility model overcomes the shortcomings of the above-mentioned technology and provides a sealing connection structure for the tea bowl of a tea tasting machine.

A sealing connector 3 is wrapped around the surface of the elastic sealing ring 2, which presses the elastic sealing ring 2 tightly against the bottom opening of the tea bowl 1. The outer wall of the sealing connector 3 located below the tea bowl 1 has several circumferentially distributed connecting protrusions 31. The sealing connection structure also includes a positioning groove 5 on the main body 4 of the tea tasting machine for the bottom of the tea bowl 1 to be placed therein. The bottom surface of the positioning groove 5 has an elastic sealing gasket 6 that abuts against the bottom surface of the sealing connector 3. The inner wall of the positioning groove 5... The surface is provided with several L-shaped grooves 7 distributed circumferentially and corresponding one-to-one with the positions of the connecting protrusions 31. The L-shaped grooves 7 include positioning sections 71 that extend downward from the upper surface of the positioning groove 5 for the connecting protrusions 31 to fall into. The L-shaped grooves 7 also include locking sections 72 that extend circumferentially from the lower end of the positioning section 71. The locking sections 72 are used to allow the connecting protrusions 31 to rotate a certain angle after falling into the lower end of the positioning section 71 in order to prevent the tea bowl 1 from falling out of the positioning groove 5. The positioning groove 5 is provided with a tea inlet 41 in the center, and the sealing connector 3 is provided with a tea outlet 32 ​​that communicates with the inner cavity of the tea bowl 1 in the center.

[0007] Preferably, the elastic sealing ring 2 has a C-shaped cross-section and the C-shaped opening is fitted into the bottom opening of the tea bowl 1.

[0008] Preferably, the sealing connector 3 includes a first sealing member 33 and a second sealing member 34. The first sealing member 33 is annular and has a U-shaped cross-section. The first sealing member 33 is inserted from bottom to top into the bottom opening of the tea bowl 1 to press the elastic sealing ring 2 against the outer bottom surface of the tea bowl 1. The second sealing member 34 is inserted from top to bottom into the bottom opening of the tea bowl 1. The second sealing member 34 includes a pressing part 341 that presses the elastic sealing ring 2 against the inner bottom surface of the tea bowl 1. The pressing part 341 has a downwardly extending connecting part 342 in the center. The connecting part 342 is inserted into the bottom opening of the tea bowl 1 and threadedly connected to the annular opening in the center of the first sealing member 33 to lock the first sealing member 33 and the second sealing member 34 to press the elastic sealing ring 2 against the bottom opening of the tea bowl 1. The tea soup outlet 32 ​​is located in the center of the connecting part 342. The connecting protrusion 31 is located on the outer wall surface of the lower end of the first sealing member 33.

[0009] Preferably, the sealing connection structure further includes a first positioning notch 11 provided at the bottom opening of the tea bowl 1, a first positioning protrusion 21 provided in the elastic sealing ring 2 that corresponds to the position of the first positioning notch 11 and can form a concave-convex fit, a second positioning notch 22 provided on the inner surface of the elastic sealing ring 2, and a second positioning protrusion 331 provided on the first sealing member 33 that corresponds to the position of the second positioning notch 22 and can form a concave-convex fit.

[0010] Preferably, the upper end of the tea outlet 32 ​​is also provided with a tea filter screen 8.

[0011] Preferably, the positioning groove 5 is further provided with a sensing component 9 for sensing whether the tea bowl 1 is placed in the correct position.

[0012] Preferably, the sensing component 9 includes a movable striker 91 disposed within the tea tasting machine body 4. The movable striker 91 is limited and installed within the tea tasting machine body 4 and can move radially along the positioning groove 5. The movable striker 91 is disposed within the tea tasting machine body 4 at a position corresponding to one of the locking sections 72 and can extend out of the tea tasting machine body 4 from the locking section 72. The tea tasting machine body 4 is also provided with a return spring 92 for driving the movable striker 91 to reset and extend out of the tea tasting machine body 4. The tea tasting machine body 4 is provided with a push button switch 93 located at one inner end of the movable striker 91. After the connecting protrusion 31 enters the locking section 72, it can push the movable striker 91 into the tea tasting machine body 4 to trigger the push button switch 93.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The sealing connection structure in this case first secures the elastic sealing ring at the bottom opening of the tea bowl, and then uses a sealing connector to provide a continuous and stable clamping force to the elastic sealing ring. This allows the elastic sealing ring to effectively fit the tea bowl, eliminating assembly gaps caused by the individual dimensional tolerances of the tea bowl. This ensures that the tea soup inside the tea bowl will not leak from any point other than the tea soup outlet. Furthermore, the seal between the tea soup outlet and the tea soup inlet is achieved through the sealing connector and the elastic sealing gasket. This avoids relying on significant dimensional fluctuations within the tea bowl for sealing, ensuring the stability of the seal. Moreover, the sealing connector and the positioning groove further lock the position of the tea bowl in place through the cooperation of the connecting protrusion and the L-shaped groove, further enhancing the reliability of the seal. Thus, the sealing connection structure in this case, through the cooperation of the elastic sealing ring, the sealing connector, the positioning groove, and the L-shaped groove, eliminates the impact of individual dimensional fluctuations of the tea bowl on the sealing performance between it and the main body of the tea tasting machine, achieving a more stable and reliable sealing connection.

[0021] The following examples provide a more detailed description of the features and other related characteristics of this utility model, to facilitate understanding by those skilled in the art:

[0022] like Figures 1 to 6As shown, a tea bowl sealing connection structure for a tea tasting machine includes an annular elastic sealing ring 2 that is fitted into the bottom opening of the tea bowl 1. A sealing connector 3 is wrapped around the surface of the elastic sealing ring 2, which is used to press the elastic sealing ring 2 tightly against the bottom opening of the tea bowl 1. The outer wall of the portion of the sealing connector 3 located below the tea bowl 1 has several circumferentially distributed connecting protrusions 31. The sealing connection structure also includes a positioning groove 5 on the main body 4 of the tea tasting machine for the bottom of the tea bowl 1 to be placed therein. The bottom surface of the positioning groove 5 has an elastic sealing gasket 6 that abuts against the bottom surface of the sealing connector 3. The positioning groove 5 contains... The wall surface is provided with several L-shaped grooves 7 distributed circumferentially and corresponding one-to-one with the positions of the connecting protrusions 31. The L-shaped grooves 7 include positioning sections 71 that extend downward from the upper surface of the positioning groove 5 for the connecting protrusions 31 to fall into. The L-shaped grooves 7 also include locking sections 72 that extend circumferentially from the lower end of the positioning section 71. The locking sections 72 are used to allow the connecting protrusions 31 to rotate a certain angle after falling into the lower end of the positioning section 71 in order to prevent the tea bowl 1 from falling out of the positioning groove 5. The positioning groove 5 is provided with a tea inlet 41 in the center, and the sealing connector 3 is provided with a tea outlet 32 ​​that communicates with the inner cavity of the tea bowl 1 in the center.

[0023] The sealing connection structure of this invention includes an elastic sealing ring 2 that is snapped into the bottom opening of the tea bowl 1, a sealing connector 3 for wrapping the elastic sealing ring 2, a positioning groove 5 on the main body 4 of the tea tasting machine, an elastic sealing gasket 6 on the bottom surface of the positioning groove 5, and an L-shaped groove 7 on the inner wall of the positioning groove 5. This invention first snaps the elastic sealing ring 2 into the bottom of the tea bowl 1 and then wraps it with the sealing connector 3. The sealing connector 3 effectively presses the elastic sealing ring 2 tightly against the bottom opening of the tea bowl 1, ensuring a tight and stable contact between the elastic sealing ring 2 and the bottom opening of the tea bowl 1, thus achieving a reliable seal. The tea outlet 32 ​​is located on the sealing connector 3, allowing the tea to flow out stably from the tea outlet 32. The main body 4 of the tea tasting machine is equipped with a positioning groove 5 for placing the tea bowl 1. A tea inlet 41, corresponding to the tea outlet 32, is located in the center of the positioning groove 5. This ensures that the tea flowing from the tea bowl 1 can be accurately returned to the tea tasting machine, allowing the machine to control whether tea is dispensed into the fairness cup. Furthermore, an elastic sealing gasket 6 is provided on the bottom surface of the positioning groove 5. When the tea bowl 1 is placed in the positioning groove 5, the sealing connector 3 abuts against the elastic sealing gasket 6. Since the tolerance fluctuation of the sealing connector 3 is much smaller than that of the tea bowl 1, the seal between the tea bowl 1 and the main body 4 of the tea tasting machine is ensured by the contact between the sealing connector 3 and the elastic sealing gasket 6.

[0024] Specifically, the sealing connector 3 is made of plastic or stainless steel, the elastic sealing ring 2 is a silicone sealing ring, and the elastic sealing gasket 6 is a silicone sealing gasket.

[0025] In addition, several circumferentially distributed connecting protrusions 31 are provided below the sealing connector 3, and L-shaped grooves 7 corresponding to the connecting protrusions 31 are provided on the wall of the positioning groove 5. In this way, when the tea bowl 1 is placed on the tea tasting machine body 4, the relative position between the tea bowl 1 and the tea tasting machine body 4 can be restricted by the connecting protrusions 31 and the L-shaped grooves 7, so that the hot water outlet of the tea tasting machine body 4 can be aligned with the hot water inlet on the tea bowl 1. Moreover, each L-shaped groove 7 includes a positioning section 71 and a locking section 72. When the tea bowl 1 is placed into the positioning groove 5, the connecting protrusions 31 can fall down along the positioning section 71, so that the tea bowl 1 can fall into the positioning groove 5. After the tea bowl 1 falls into place, rotating the tea bowl 1 will cause the connecting protrusions 31 to rotate into the locking section 72. In this way, the connecting protrusions 31 cannot move upward, thus locking the tea bowl 1 and preventing the tea bowl 1 from being disturbed by external force and falling out of the positioning groove 5. At the same time, it can also further ensure that the sealing connector 3 and the elastic sealing gasket 6 can make tight contact to achieve a seal.

[0026] As described above, the sealing connection structure of this invention first places the elastic sealing ring 2 at the bottom opening of the tea bowl 1, and then uses the sealing connector 3 to provide a continuous and stable clamping force to the elastic sealing ring 2. This allows the elastic sealing ring 2 to effectively fit onto the tea bowl 1, eliminating the assembly gap caused by the individual dimensional tolerances of the tea bowl 1. This ensures that the tea soup inside the tea bowl 1 will not leak from any point other than the tea soup outlet 32. Furthermore, the seal between the tea soup outlet 32 ​​and the tea soup inlet 41 is achieved through the sealing connector 3 and the elastic sealing gasket 6. This avoids relying on the large dimensional fluctuations of the tea bowl 1 for sealing, ensuring the stability of the seal. Moreover, the sealing connector 3 and the positioning groove 5 can further lock the position of the tea bowl 1 through the cooperation of the connecting protrusion 31 and the L-shaped groove 7, thereby further enhancing the reliability of the seal. Thus, the sealing connection structure of this invention, through the cooperation of the elastic sealing ring 2, the sealing connector 3, the positioning groove 5, and the L-shaped groove 7, can eliminate the influence of the dimensional fluctuations of the individual tea bowl 1 on the sealing performance between it and the tea tasting machine body 4, achieving a more stable and reliable sealing connection.

[0027] like Figure 3 and Figure 6As shown, preferably, the elastic sealing ring 2 has a C-shaped cross-section and the C-shaped opening is fitted into the bottom opening of the tea bowl 1. In this way, by designing the elastic sealing ring 2 as C-shaped, a maze structure can be formed between the tea bowl 1 and the elastic sealing ring 2. Thus, by wrapping the elastic sealing ring 2 with the sealing connector 3 and pressing the elastic sealing ring 2 tightly onto the surface of the tea bowl 1, the deformation of the elastic sealing ring 2 can be utilized as much as possible to conform to the shape changes of the tea bowl 1, thereby eliminating the influence of the shape and size changes of the tea bowl 1 on the sealing performance.

[0028] like Figures 2 to 6 As shown, preferably, the sealing connector 3 includes a first sealing member 33 and a second sealing member 34. The first sealing member 33 is annular and has a U-shaped cross-section. The first sealing member 33 is inserted into the bottom opening of the tea bowl 1 from bottom to top to press the elastic sealing ring 2 against the outer bottom surface of the tea bowl 1. The second sealing member 34 is inserted into the bottom opening of the tea bowl 1 from top to bottom. The second sealing member 34 includes a pressing part 341 that presses the elastic sealing ring 2 against the inner bottom surface of the tea bowl 1. The pressing part 341 has a downwardly extending connecting part 342 in the center. The connecting part 342 is inserted into the bottom opening of the tea bowl 1 and threadedly connected to the annular opening in the center of the first sealing member 33 to lock the first sealing member 33 and the second sealing member 34 to press the elastic sealing ring 2 against the bottom opening of the tea bowl 1. The tea soup outlet 32 ​​is located in the center of the connecting part 342. The connecting protrusion 31 is located on the outer wall surface of the lower end of the first sealing member 33.

[0029] As described above, the sealing connector 3 in this case includes a first sealing element 33 and a second sealing element 34. The U-shaped first sealing element 33 is inserted into the bottom of the tea bowl 1 from bottom to top, thus pressing the elastic sealing ring 2 against the bottom opening of the tea bowl 1 from bottom to top. The second sealing element 34 is inserted into the bottom opening of the tea bowl 1 from top to bottom. The second sealing element 34 is provided with a pressing part 341 and a connecting part 342. The pressing part 341 can press the elastic sealing ring 2 against the bottom of the tea bowl 1 from top to bottom. Then, the connecting part 342 is connected to the annular opening thread in the center of the first sealing element 33, thus locking the first sealing element 33 and the second sealing element 34 together. This provides both upward and downward pressing forces to the elastic sealing ring 2, ensuring a tight fit between the elastic sealing ring 2 and the tea bowl 1. Moreover, the first sealing element 33 located at the bottom of the tea bowl 1 can also continue to serve as a dimensionally stable intermediate part for connection and sealing with the tea tasting machine body 4, so as to eliminate the influence of the shape and size fluctuation of the tea bowl 1 on the seal between it and the tea tasting machine body 4.

[0030] like Figure 5 and Figure 6As shown, preferably, the sealing connection structure further includes a first positioning notch 11 provided at the bottom opening of the tea bowl 1, a first positioning protrusion 21 provided in the elastic sealing ring 2 that corresponds to the position of the first positioning notch 11 and can form a concave-convex fit, a second positioning notch 22 provided on the inner surface of the elastic sealing ring 2, and a second positioning protrusion 331 provided on the first sealing member 33 that corresponds to the position of the second positioning notch 22 and can form a concave-convex fit.

[0031] As described above, the relative positions of the elastic sealing ring 2 and the tea bowl 1 can be locked by the cooperation of the first positioning notch 11 and the first positioning protrusion 21. The relative positions of the first sealing element 33 and the elastic sealing ring 2 can be locked by the cooperation of the second positioning notch 22 and the second positioning protrusion 331. This prevents the first sealing element 33 and the second sealing element 34 from rotating relative to each other during the threaded connection process, thus avoiding the elastic sealing ring 2 from shifting relative to the tea bowl 1 and causing wrinkles that affect the sealing effect. Furthermore, by locking the relative positions of the tea bowl 1, the elastic sealing ring 2, and the first sealing element 33, the relative position of the connecting protrusion 31 and the tea bowl 1 can also be indirectly locked. Finally, the cooperation of the connecting protrusion 31 and the L-shaped groove 7 can lock the relative positions of the tea bowl 1 and the tea tasting machine body 4, ensuring accurate alignment.

[0032] like Figure 3 and Figure 5 As shown, preferably, the upper end of the tea outlet 32 ​​is also provided with a tea filter 8. In this way, the tea in the tea bowl 1 can be prevented from leaking from the tea outlet 32 ​​and entering the tea tasting machine body 4 through the tea filter 8. Moreover, in this case, the tea filter 8 is set at the upper end of the tea outlet 32, which can further prevent tea from entering the tea outlet 32 ​​and clogging the tea outlet 32.

[0033] like Figure 2 and Figure 4 As shown, preferably, the positioning groove 5 is also provided with a sensing component 9 for sensing whether the tea bowl 1 is placed in place. In this way, by setting the sensing component 9, it can be ensured that the tea brewing operation is only performed after the tea bowl 1 is connected to the tea tasting machine body 4, so as to avoid water leakage caused by starting the tea brewing program before the tea bowl 1 is placed in place and the tea bowl 1 and the tea tasting machine body 4 have been fully sealed.

[0034] like Figure 2 and Figure 4As shown, preferably, the sensing component 9 includes a movable striker 91 disposed within the tea tasting machine body 4. The movable striker 91 is limited and installed within the tea tasting machine body 4 and can move radially along the positioning groove 5. The movable striker 91 is disposed within the tea tasting machine body 4 at a position corresponding to one of the locking sections 72 and can extend out of the tea tasting machine body 4 from the locking section 72. The tea tasting machine body 4 is also provided with a return spring 92 for driving the movable striker 91 to reset and extend out of the tea tasting machine body 4. The tea tasting machine body 4 is provided with a push button switch 93 located at one inner end of the movable striker 91. After the connecting protrusion 31 enters the locking section 72, it can push the movable striker 91 into the tea tasting machine body 4 to trigger the push button switch 93.

[0035] As described above, the sensing component 9 in this case includes a movable striking pin 91, a return spring 92, and a push-button switch 93. When the tea bowl 1 is not placed in position on the tea tasting machine body 4, the movable striking pin 91 extends into the tea tasting machine body 4 under the drive of the return spring 92 and does not trigger the push-button switch 93. When the tea bowl 1 is placed in position, the connecting protrusion 31 enters the corresponding locking section 72, and the movable striking pin 91 extending outward from one of the locking sections 72 is simultaneously pressed into the tea tasting machine body 4 by the connecting protrusion 31. After being pressed by the connecting protrusion 31, the movable striking pin 91 can overcome the elastic force of the return spring 92 and retract into the tea tasting machine body 4, simultaneously triggering the push-button switch 93. In this way, the tea tasting machine body 4 can determine whether the tea bowl 1 is placed in position and thus determine whether the tea brewing program can be started by the triggering state of the push-button switch 93.

[0036] As stated above, this case protects a sealing connection structure for a tea bowl in a tea tasting machine, and all technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
