Currently, there are tea machines on the market that can replace tea bags. These not only ensure healthy drinking water but also allow the brewing of a variety of teas, meeting the diverse needs of the market. To brew a variety of teas, one only needs to replace the corresponding tea eggs with the tea bag jar of the tea machine. Different tea machines have different ways of opening the tea bag jar, with some opening manually and some opening automatically. When a tea bag is placed in a tea machine that automatically opens the tea bag jar, the machine's detection chip will sense it and then start the motor to close the tea bag jar opening. If the user does not pay attention at this time and does not remove their hands or other objects from the opening, they will be pinched by the tea machine, posing a certain safety hazard.

[0021] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.
[0022] like Figures 1 to 5 As shown, the anti-pinch mechanism includes an upper panel 1 of the tea machine, which is provided with a first opening 11. A support frame 2 is provided below the upper panel 1 and is located on the upper side of the tea machine. A second opening 21 is provided at the top of the support frame 2, opposite to the first opening 11, and is shaped like a tea bag.
[0023] A motor bracket 22 is fixed to the rear end of the support frame 2, and a water outlet bracket 23 is set on the inner side of the front end. A sliding track 3 is set between the motor bracket 22 and the water outlet bracket 23, and the sliding track 3 is set on the left and right sides of the motor bracket 22 and the water outlet bracket 23.
[0024] The sliding rails 3 on the left and right sides are both sleeved with sliding brackets 5, and the sliding brackets 5 include a first bracket 51 at the front end and a second bracket 52 at the rear end. The inner sides of the first bracket 51 and the second bracket 52 are connected to each other, and the rear ends of the sliding brackets 5 on the left and right sides are connected to each other by an annular connector 53. A tea bag canister 8 is fixed at the front end. A gap is provided in the middle of the sliding brackets 5 on both sides. The front end of the tea bag canister 8 is adapted to the water outlet, and the water outlet is provided in the middle of the water outlet bracket 23; a thread is provided on the inner side of the annular connector 53.
[0025] A moving assembly 6 is sleeved on the sliding track 3 between the first brackets 51 and the second brackets 52 on both sides. The moving assembly 6 includes a moving bracket 61 and a moving plate 62. The moving plate 62 is close to the first bracket 51 and extends upward. A moving plate 62 extending forward is fixed on the top. The moving plate 62 is located between the support frame 2 and the upper side plate 1. When the tea machine is closed, the moving plate 62 is located between the first opening 11 and the second opening 21; a spring 7 is sleeved on the sliding track 3 between the rear end of the moving bracket 61 on both sides and the motor bracket 22. One end of the spring 7 is against the rear end of the moving bracket 61, and the other end is against the front end of the second bracket 52. Under normal conditions, the spring 7 is in a balanced state.
[0026] The motor 4 is provided at the rear end of the motor bracket 22, and a screw 41 extends to the front end of the motor 4. The screw 41 passes through the motor bracket 22 and is fixed to the annular connector at the rear end of the sliding bracket 5 through a flange. The screw 41 is adapted to the thread inside the annular connector.
[0027] When the tea bag needs to be placed, the motor 4 drives the screw 41 to rotate, the annular connecting member 53 is driven to move to the rear side of the screw 41, and the screw 41 enters the gap between the two movable brackets 5, and the annular connecting member 53 drives the entire sliding bracket 5 to move backward, and the first bracket 51 of the sliding bracket 5 pushes the movable assembly 6 to move backward, and the movable plate 62 leaves between the first opening 11 and the second opening 21. The first opening 11 and the second opening 21 are opened. At this time, the tea bag can be placed. When the tea bag is placed, the tea drinking machine chip sends a signal, the motor 4 drives the screw in the opposite direction, the annular connecting member 53 is driven to move forward, and the movable plate 62 is driven to move forward to close the first opening 11 and the second opening 21. At this time, if the user's hand or other object has not been retracted in time, the movable plate 62 cannot be reset. At this time, the spring 7 is compressed, giving the movable plate 62 a buffering force, so that the user's hand or object will not be pinched or damaged. At the same time, when the hand or object leaves, the reset of the spring 7 can drive the movable plate 62 to reset.
[0028] The anti-hand pinching mechanism of the present invention is achieved by arranging a moving component 6 between the first bracket 51 and the second bracket 52 of the sliding bracket 5, and arranging the moving bracket 61 at the rear end of the first bracket 51. A spring 7 is arranged between the rear end of the moving bracket 61 and the second bracket 52. When the moving plate 62 is driven forward, if the user's hand or other object does not have time to leave the second opening 21, the moving plate 62 cannot be reset. The spring 7 provides a buffering force to the moving plate 62 to prevent the user's hand or object from being pinched or damaged. At the same time, when the hand or object leaves, the reset of the spring 7 can drive the moving plate 62 to reset.
[0029] Finally, it should be noted that the above embodiments only illustrate the technical solutions of the present invention, rather than limiting it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
