Description

Technical Field

[0001] The present invention relates to the field of household appliances, and more particularly to a tea dispenser capable of electrically controlling the brewing, brewing, dispensing, or dispensing of pure water. The infusion material includes, but is not limited to, tea leaves, and may also include other materials such as chrysanthemum, rose, and isatis root. The pure water may be pure cold water, pure warm water, or pure hot water. Background Art

[0002] China's tea-drinking culture has a long and rich history, and it has become a habit, a constant companion in our work and daily lives. However, the ease of brewing—and the ease of disassembly and cleaning—is a key factor influencing the tea-drinking experience.

[0003] The Chinese utility model patent with patent publication number CN210871091U discloses a brewing chamber structure and an automatic tea and water brewing machine. The brewing chamber adopts a top water filling and bottom water dispensing scheme. If you want to disassemble and clean it, it is extremely inconvenient. Therefore, there is a great need to improve it. Summary of the Invention

[0004] Aiming at the problem that the tea brewing machine in the background technology is inconvenient to disassemble and clean, a tea brewing machine is provided in which water is poured in and out from the bottom of the tea drinking chamber, thereby overcoming the problem that the tea brewing machine in the background technology is inconvenient to disassemble and clean.

[0005] The technical solutions adopted are:

[0006] A tea drinking machine is provided, comprising a tea drinking bin placement cavity, a tea drinking bin, a buffer chamber, a water inlet, and an opening and closing portion; the tea drinking bin is at least partially located in the tea drinking bin placement cavity, the tea drinking bin has a tea drinking bin outlet, the buffer chamber has a buffer chamber inlet, and the tea drinking bin outlet and the buffer chamber inlet are directly or indirectly abutted; a wall of the buffer chamber is provided with a water inlet, and the water inlet is controlled to inject water into the buffer chamber; the buffer chamber is provided with a buffer chamber outlet, and the opening and closing portion is used to open and close the buffer chamber outlet.

[0007] The technical solution of the present invention also provides a control method for a tea drinking machine. For the tea drinking machine as described above, when water is added, the opening and closing part closes the outlet of the buffer chamber, the water inlet part opens, the water inlet part adds water to the buffer chamber, and the buffer chamber adds water to the tea drinking chamber through the outlet of the tea drinking chamber.

[0008] The beneficial effect of the above technical solution is that a water inlet is provided on the side wall of the buffer chamber. When filling water, the water inlet is opened and water is filled into the buffer chamber, and then the buffer chamber fills water into the tea drinking warehouse through the tea drinking warehouse outlet. At the same time, the opening and closing part closes the buffer chamber outlet; when discharging water, the tea drinking warehouse fills water into the buffer chamber and closes the water inlet, so that the tea drinking warehouse uses the same opening for water inlet and water outlet, making it easy to disassemble the tea drinking warehouse.

[0009] Specifically, the advantages of the above technical solution are as follows:

[0010] The tea drinking warehouse is filled with drinks and taken out of drinks through the tea drinking warehouse outlet, which greatly facilitates the disassembly and cleaning of the tea drinking warehouse. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] like Figure 2 As shown, the tea drinking machine of this embodiment includes a tea drinking bin placement cavity 1, a tea drinking bin 2, a buffer chamber 3, a water inlet 4, and an opening and closing portion 5; the tea drinking bin 2 is at least partially located in the tea drinking bin placement cavity 1, the tea drinking bin 2 has a tea drinking bin outlet 21, and the buffer chamber 3 has a buffer chamber inlet 31, the tea drinking bin outlet 21 and the buffer chamber inlet 31 are directly abutted, or indirectly abutted through the elastic member 13, or indirectly abutted through the bottom wall of the tea drinking bin placement cavity 1 and the elastic member 13 in sequence, or indirectly abutted against the bottom wall of the tea drinking bin placement cavity 1; the wall 32 of the buffer chamber 3 is provided with a water inlet 4, and the water inlet 4 is controlled to inject water into the buffer chamber 3; the buffer chamber 3 is provided with a buffer chamber outlet 33, and the opening and closing portion 5 is used to open and close the buffer chamber outlet 33. This design solution can realize that the water inlet and outlet of the tea drinking bin 2 share the same bottom opening. When disassembling, there is no need to disassemble the water outlet and the water inlet separately at the same time. This facilitates disassembly and increases the convenience of cleaning the tea drinking bin 2.

[0029] The tea drinking machine has a water inlet opening and closing valve 6 , which is connected to the water inlet part 4 . The water inlet opening and closing valve 6 is used to control the opening and closing of the water inlet part 4 and control the water flow of the water inlet part 4 .

[0030] The buffer chamber 3 includes a push rod 34. The tea container 2 includes an opening and closing valve column 22 and an opening and closing spring 23. The opening and closing spring 23 is connected to the tea container outlet 21 and the opening and closing valve column 22, respectively. The push rod 34 is connected to the opening and closing valve column 22. When the tea container 2 is removed, the push rod 34 releases the opening and closing valve column 22, and the spring 23 presses down on the opening and closing valve column 22, closing the tea container outlet 21. When the tea container 2 is removed, the push rod 34 prevents tea in the tea container 2 from dripping onto the ground or into the tea container storage chamber 1. When the tea container 2 is placed on the tea container storage chamber 1, the push rod 34 lifts the opening and closing valve column 22, which compresses the spring 23, opening the tea container outlet 21. This establishes fluid communication between the tea container 2 and the buffer chamber 3, allowing the tea container 2 to pour tea into the buffer chamber 3, or for the buffer chamber 3 to pour water into the tea container 2. Preferably, the bottom wall of the tea drinking chamber 2 is provided with an opening and closing valve post 22, so that the tea drinking chamber 2 is more easily opened by gravity when placed on the tea drinking chamber placement cavity 1. Preferably, when the opening and closing spring 23 is subjected to the weight of the tea drinking chamber 2, the opening and closing spring 23 is compressed to automatically open the tea drinking chamber outlet 21; preferably, the opening amount is 100%, so that the maximum flow rate is opened.

[0037] When the buffer chamber 3 is opened, the motor 93 drives the rotating rod 92 to rotate, and the threaded spiral on the rotating rod 92 drives the pushing member 91 to move forward along the third direction zz. The second pushing surface 911 on the pushing member 91 presses down the first pushing surface 821 on the second force transmission part 82, and the second force transmission part 82 pulls down the first force transmission part 81. The first force transmission part 81 pulls down the opening and closing part 5 while compressing the spring 10, and the opening and closing part 5 opens the buffer chamber 3.

[0041] When the buffer chamber 3 is opened, the motor 93 drives the rotating rod 92 to rotate, and the rotating rod 92 drives the second force transmission part 82 to rotate. The slide push surface 821 of the second force transmission part 82 releases the sliding spherical surface 811 of the first force transmission part 81, and the spring 10 presses the first force transmission part 81 to move downward. The first force transmission part 81 brings the opening and closing part 5 to open the buffer chamber 3.

[0042] When the buffer chamber 3 is closed, the motor 93 drives the rotating rod 92 to rotate, and the rotating rod 92 drives the second force transmission part 82 to rotate. The second force transmission part 82 pushes the first force transmission part 81 upward, and the second force transmission part 82 overcomes the elastic force of the spring 10, pressing the first force transmission part 81 to move upward, and the first force transmission part 81 moves upward with the opening and closing part 5, and finally abuts against the buffer chamber outlet 33.
