Description

Technical Field

[0001] The utility model relates to the technical field of tea brewing cups, in particular to a novel siphon type tea brewing cup. Background Art

[0002] Tea not only has pharmacological effects such as refreshing the mind, clearing away heat and relieving summer heat, digesting food and reducing phlegm, detoxifying and sobering up, promoting fluid production and quenching thirst, reducing fire and improving eyesight, but also has certain pharmacological effects on cardiovascular and cerebrovascular diseases, cancer and other diseases. Tea cups or pots are widely used in people's daily lives.

[0003] There is a Chinese utility model patent published on April 24, 2020, with the announcement number CN210383538U, which is an improved structure of a tea brewing cup. The structure of this product is simple, with few parts, easy to clean and carry, and it can also allow users to recognize and experience the simple siphon phenomenon, which increases the fun and leisure of tea brewing. However, when the water level of the tea brewing cup is lower than the upper top surface of the drainage column, water cannot flow out. When the water level is higher than the upper top surface of the drainage column, the water in the tea brewing chamber will continue to flow out, and the siphon effect cannot be interrupted at will. It is necessary to wait until the water level is no higher than the gap at the bottom of the drainage cover. Therefore, it is impossible to stop the water discharge according to the amount of water people need, which is very inconvenient to use.

[0004] There is also a Chinese utility model patent published on April 28, 2023, with a publication number of CN218922260U, which is a floating cup. The cup lid has a built-in strong magnet, and the steel ball blocks the drain by its own gravity during the tea brewing process. When the tea needs to be released, you only need to rotate the cup lid so that the strong magnet adsorbs the top of the stainless steel suction block to generate adsorption force, and then lift the steel ball to open the drain to release the tea. There is no need to press during use, which is more convenient to use. Although this floating cup can stop discharging water according to the amount of water people need, the addition of blocks, stainless steel suction blocks, steel balls, strong magnets and other structures greatly increases the production cost, and the steel balls are soaked in tea, which will cause air oxidation and cause the steel balls to rust. The chemical reactions generated when using this container to make tea will affect people's health, there are certain safety hazards, and it is inconvenient to clean. At the same time, when the floating cup needs to be added with water twice or more, the steel ball needs to be adjusted to reset and block the drain, which is relatively troublesome.

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments. However, the following embodiments are only preferred embodiments of the present invention, not all of them. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work all belong to the protection scope of the present invention. The experimental methods in the following embodiments are conventional methods unless otherwise specified. The materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0032] like Figure 1-Figure 8 As shown, the utility model provides a novel siphon tea brewing cup, comprising a cup body 1, a drainage unit, a cup cover 4, a sealing member 5 and a ventilation structure 6;

[0033] The drainage unit includes a drainage cover 2 and a drainage member 3. The drainage cover 2 is arranged on the inner bottom surface of the cup body 1. At least one water inlet 21 is opened at the bottom of the drainage cover 2. The drainage member 3 is fixed to the inner bottom surface of the cup body 1. The internal space formed by the drainage cover 2 and the bottom surface of the cup body 1 is divided into a connected water inlet channel 22 and a water outlet channel 23. There is a gap between the inner top wall of the drainage cover 2 and the top surface of the drainage member 3. The water outlet channel 23 passes through the bottom of the cup body 1. The water inlet 21 is connected to the water inlet channel 22.

[0034] Specifically, the drainage cover 2 is a columnar structure with a closed upper end and an open lower end, and the water inlet 21 is provided at the edge of the opening;

[0035] The cup cover 4 is arranged on the opening of the cup body 1;

[0036] The sealing member 5 is arranged on the bottom surface of the cup cover 4, between the cup cover 4 and the cup body 1, and its size is adapted to the size of the opening of the cup body 1, and the sealing member 5 is elastic;

[0037] The ventilation structure 6 is arranged on the outer wall of the tea brewing cup, and the height of the ventilation structure 6 is higher than the height of the top surface of the drainage member 3 (it should be noted that a mark corresponding to the height of the top surface of the drainage member 3 is arranged on the inner wall of the cup body 1, so that people can know the water level corresponding to the height of the top surface of the drainage member 3);

[0038] Embodiment 1:

[0039] like Figure 1 , Figure 4 and Figure 5 As shown, the ventilation structure 6 is a first through hole, which is opened on the top surface of the cup cover 4, and the first through hole is connected to the inside of the cup body 1:

[0040] When the water level is higher than the top surface of the drainage member 3, the water in the cup body 1 will be directly discharged through the water outlet channel 23 under the siphon principle until the water level in the cup body 1 is lower than the water inlet 21. This is the prior art and will not be described in detail here.

[0041] When water is added to the cup body 1 so that the water level is lower than the top surface height of the drainage member 3 and water is needed to be discharged, the cup cover 4 is covered to make the sealing member 5 fit with the opening of the cup body 1, and then the cup cover 4 is pressed down (the first through hole is not blocked here) to compress the elastic sealing member 5. At this time, the pressure in the cup body 1 increases. Due to the sealing effect of the sealing member 5 and the cup cover 4, the pressure is mainly released from the first through hole and the water outlet channel 23. The pressure causes the water in the cup body 1 to be discharged through the water outlet channel 23. Then the cup cover 4 is released, the sealing member 5 rebounds, the pressure in the cup body 1 decreases, the first through hole begins to take in air, and the water in the water outlet channel 23 will continue to be discharged through the water outlet channel 23 after a small amount of back drawing due to the influence of gravity. The first through hole continues to take in air, and the water outlet channel 23 continues to discharge water until the water level in the cup body 1 is lower than the water inlet 21, so that water can still be discharged even when the water level in the cup body 1 is lower than the top surface height of the drainage member 3.

[0042] On the contrary, when it is necessary to interrupt the water flow (regardless of whether the water level in the cup body 1 is lower than or higher than the top surface height position of the drainage piece 3 or the water level in the cup body 1 is flush with the top surface height position of the drainage piece 3), block the first through hole with your hand and then press down the cup cover 4. At this time, the pressure in the cup body 1 increases. Due to the sealing effect of the seal 5 and the cup cover 4, the pressure is mainly released from the water outlet channel 23. The pressure causes the water in the cup body 1 to be discharged through the water outlet channel 23. Then release the cup cover 4, the seal 5 rebounds, and the fingers continue to seal the first through hole, causing the amount of water pumped back into the water outlet channel 23 to surge. There is no water in the water outlet channel 23, thereby interrupting the siphon effect and achieving the effect of interrupting the water flow.

[0043] The tea brewing cup has a simple structure and is easy to use. When water is added into the cup body 1 so that the water level is lower than the top surface height of the drainage piece 3, the water discharge from the cup body 1 can be controlled, and the water discharge can be stopped according to the amount of water required by people. At the same time, the existing tea brewing cups that require the blocks, stainless steel suction blocks, steel balls, strong magnets and other structures for controlling the water discharge are omitted, thereby reducing production costs without affecting people's health. At the same time, when water needs to be added twice or multiple times, the trouble of adjusting the steel ball to return to its original position to block the water outlet in the existing floating cup is avoided.

[0044] Embodiment 2:

[0045] like Figure 2 As shown, the ventilation structure 6 is a second through hole, which is opened above one side of the outer wall of the cup body 1;

[0046] The specific usage is similar to the description of the first embodiment and will not be repeated here.

[0047] Embodiment three:

[0048] like Figure 3As shown, the ventilation structure 6 is a gap, the material of the seal 5 is silicone, there is a gap between the outer periphery of the seal 5 and the bottom surface of the cup cover 4, so that the cup cover 4 will not seal the gap, and at least one gap is opened on the outer periphery of the seal 5;

[0049] The specific usage is similar to the description of the first embodiment and will not be repeated here.

[0050] The flow guide 3 can be set to the following two situations:

[0051] like Figure 4 and Figure 6 As shown, when the drainage member 3 is a partition, the two opposite sides of the partition are in contact with the inner wall of the drainage cover 2. At this time, the drainage member 3 and the drainage cover 2 can be regarded as a whole;

[0052] like Figure 5 and Figure 7 As shown, when the drainage member 3 is a hollow column, the inner space of the hollow column is the water outlet channel 23, and the outer wall of the hollow column does not contact the inner wall of the drainage cover 2;

[0053] The settings of the two drainage parts 3 and the drainage cover 2 are both common settings of the existing siphon structure. Specifically, when the water level is higher than the top surface position of the drainage part 3, the water in the cup body 1 will be discharged directly through the water outlet channel 23 under the siphon principle until the water level in the cup body 1 is lower than the water inlet 21.

[0054] The drainage cover 2 and the drainage member 3 are both detachably arranged in the cup body 1;

[0055] By removably fixing the drainage cover 2 and the drainage member 3 in the cup body 1, the drainage cover 2 and the drainage member 3 can be regularly removed, cleaned or replaced to avoid excessive scale adhering thereto.

[0056] like Figure 3 and Figure 4 As shown, the top surface of the drainage member 3 is higher than the middle position of the inner wall of the cup body 1, ensuring that the siphon principle is used for drainage only after a sufficient amount of water is poured into the cup body 1.

[0057] like Figure 1 , Figure 4 and Figure 8 As shown, on the basis of the first embodiment, a one-way valve 7 is provided in the first through hole, and a silicone material can be used here. The one-way valve 7 includes a closing surface 71, a flexible rod 72 and a connecting rod 73. The connecting rod 73 is located in the first through hole, and the two ends of the connecting rod 73 are respectively perpendicular to the closing surface 71 and the flexible rod 72. The closing surface 71 is in contact with the bottom surface of the cup cover 4, and the flexible rod 72 is horizontally located on the top surface of the cup cover 4. The cross-sectional sizes of the flexible rod 72 and the connecting rod 73 are both smaller than the opening size of the first through hole, ensuring that the flexible rod 72 and the connecting rod 73 will not close the first through hole, thereby ensuring the normal air intake of the first through hole;

[0058] When the cup cover 4 is pressed down, the pressure in the cup body 1 increases, and the gas pushes the closing surface 71 against the bottom surface of the cup cover 4, so that the closing surface 71 closes the first through hole, so that no gas will be discharged from the first through hole, and the pressure will not be released from the first through hole, ensuring that the pressure causes the water in the cup body 1 to be discharged through the water outlet channel 23. Subsequently, the cup cover 4 is no longer pressed down. When the cup cover 4 rebounds, the pressure in the cup body 1 decreases, and the air pushes the closing surface 71 open through the first through hole and enters the cup body 1, thereby achieving normal air intake. The water outlet channel 23 continues to discharge water until the water level in the cup body 1 is lower than the water inlet 21, so that water can still be discharged even if the water level in the cup body 1 is lower than the top surface height of the drainage member 3.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
