Description

Technical Field

[0001] The utility model relates to the technical field of electrical appliances, and more specifically to a tea basket lifting structure and a tea brewing machine with this structure. Background Art

[0002] With the improvement of people's living standards, tea brewing machines are widely used in family or office occasions. Some tea brewing machines also have a tea basket lifting structure, which allows users to adjust the soaking time of tea in the tea water according to personal taste to control the concentration of the tea soup. However, the existing tea basket lifting structures usually adopt chain or spring or vertical rack drive, which requires high-precision matching, resulting in high production costs; some also use air valves and air pumps for driving, which not only have high costs, but also the air duct interfaces are extremely prone to air leakage due to poor sealing, resulting in drive failure.

[0003] In order to reduce costs, for example, Chinese Patent No. CN207821657U discloses a magnetic traction type lifting tea steaming machine. One end of a steel wire rope is connected to a fixed pulley, and the other end is connected to a motor. A first magnet is fixed on the steel wire rope. Although this prior art uses a steel wire rope drive and can save costs, its tea basket can actually only complete one-way movement. That is, when the motor contracts the steel wire rope, it pulls the magnet, and the magnet and the tea basket attract each other. The frictional force generated on the tea basket is greater than the gravity, and the tea basket moves upward; when the motor lengthens the steel wire rope, since the steel wire rope is flexible and there is no thrust, and the magnet and the tea basket attract each other, its own gravity is not enough to overcome the frictional force and it will stay in the original position. It can be seen that the prior art lacks a tea basket lifting structure that can not only realize the up and down movement of the tea basket, but also reduce costs. Summary of the Utility Model

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides a tea basket lifting structure and a tea brewing machine with this structure, which has a simple structure and can reduce costs.

[0012] In a preferred technical solution, the pull rope is a nylon rope, which further reduces the cost.

[0013] In a preferred technical solution, the pull rope is a metal rope, which is more durable.

[0014] Furthermore, the pull rope is a steel wire rope, which is convenient to obtain materials and is durable.

In addition, in the description of the present invention, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0031] Refer to Figure 1-8 Describe a tea basket lifting structure and a tea brewing machine having the structure according to an embodiment of the present invention. The tea basket lifting structure can be applied to an electric kettle, especially a tea brewing machine.

[0032] In one embodiment, as Figure 1-4 shown, a tea basket lifting structure includes a pulling rope 2, a magnet box 3, a tea basket 4, a fixed pulley 1, a bush 5 and a motor 6. Among them, the pulling rope 2 can be a nylon rope or a metal rope, which has the advantages of being strong, durable and low cost. The position of the fixed pulley 1 is fixed with that of the motor 6, and the fixed pulley 1 is located above the motor 6. The bush 5 is sleeved on the rotating shaft of the motor 6. One end of the pulling rope 2 bypasses the fixed pulley 1 and is fixed on the magnet box 3. After the other end of the pulling rope 2 winds around the bush 5 for several turns to form a first winding 21, it passes through the rotating shaft of the motor 6, then winds around the bush 5 for several turns to form a second winding 22, and finally is fixed on the magnet box 3. A first magnet 31 is arranged in the magnet box 3, and a second magnet 41 is arranged on the tea basket 4. The first magnet 31 and the second magnet 41 attract each other with opposite polarities.

[0033] Among them, the fixed pulley 1 is located above, the motor 6 and the bushing 5 are located below, the pulling rope 2 is arranged between the fixed pulley 1 and the bushing 5, and the first winding 21 and the second winding 22 are windings in the same direction; the first magnet 31 and the second magnet 41 can be made of magnets, which are convenient to obtain materials and low in price, and are beneficial to reducing costs.

[0034] During specific implementation, after the motor 6 is powered on, it drives the bushing 5 to rotate. The two windings on the bushing 5 can make the lengths of the two parts of the rope outside the bushing 5 change by taking in and releasing. Since the two ends of the pulling rope 2 are fixed on the magnet box 3, the magnet box 3 can move up and down under the pulling of the pulling rope 2, and the corresponding external tea basket 4 moves accordingly under the action of magnetic force.

[0035] As Figure 1-4 shown, when the magnet box 3 needs to move upward, the motor 6 rotates to increase the number of turns of the first winding 21 and decrease the number of turns of the second winding 22. Then the magnet box 3 is subjected to the upward pulling force of the pulling rope 2 above the magnet box 3, and the magnet box 3 moves upward. At this time, the tea basket lifting structure is in Figure 1-2 the first state shown; when the magnet box 3 needs to move downward, the motor 6 rotates to increase the number of turns of the second winding 22 and decrease the number of turns of the first winding 21. Then the magnet box 3 is subjected to the downward pulling force of the pulling rope 2 below the magnet box 3, and the magnet box 3 moves downward. At this time, the tea basket lifting structure is in Figure 3-4 the second state shown, so as to realize the free up and down movement of the magnet box 3. That is, the motor 6 rotates to change the number of turns of the two windings, thereby driving the up and down movement of the magnet box 3, and the tea basket 4 moves accordingly.

[0036] The tea basket lifting structure provided by the above embodiment can conveniently realize the up and down movement of the tea basket 4 through the pulling rope 2 driven by the motor 6 and the magnet. The structure is simple, and the precision requirements for the components are not high, which can effectively reduce the production cost.
