[0016] Figure 3 for Figure 1 sectional view of . DETAILED DESCRIPTION

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0018] like Figure 1 ,2 As shown in Figure 3, a blender with a pressure-relief and explosion-proof cup cover, the blender includes a main unit 1, a knife holder 4, a cup body 2 and a pressure-relief and explosion-proof cup cover 3. The main unit 1 is provided with a motor 5 and a control system. The middle part of the pressure-relief and explosion-proof cup cover 3 is provided with a pressure-relief cylinder 31 with an opening at a lower end protruding upward and downward. A pressure-relief port 32 is provided on one side of the upper end of the pressure-relief cylinder 3. A downwardly extending enclosure 33 is formed on the inner side of the top surface of the pressure-relief cylinder 31 and around the pressure-relief port 32. A horizontal baffle 34 is provided in the pressure-relief cylinder 31 to abut against the lower end of the enclosure 33, and a pressure-relief hole 35 is provided at the junction of the baffle 34 and the enclosure 33.

[0019] The specific structure is as follows: the upper end of the cup body 2 is formed with a reduced diameter external threaded connection section, the lower inner wall of the pressure relief explosion-proof cup cover 3 has a corresponding internal thread, and the pressure relief explosion-proof cup cover 3 is connected and fixed to the upper end of the cup body 2 by threaded connection. The pressure relief cylinder 31 is cylindrical, and its height is greater than the height of the pressure relief explosion-proof cup cover 3. The lower end of the pressure relief cylinder 31 extends to below the external threaded connection section of the cup body 2. The pressure relief port 32 is opened close to the wall of the pressure relief cylinder 3, and the baffle 33 is horizontally arranged in the middle and lower part of the inner wall of the pressure relief cylinder 31. The outer peripheral surface of the pressure relief explosion-proof cup cover 3 is provided with a concave and convex surface 36 for easy manual rotation.

[0020] The lower end of the cup body 2 is connected and fixed to the knife holder 4 by threaded connection. After the cup body 2 and the knife holder 4 are connected, a cup assembly is formed. A knife holder 6 with a blade is provided in the knife holder 4. The motor 5 is fixedly installed in the center of the host 1. The output shaft of the motor 5 extends out of the host 1. The upper end of the host 1 is provided with a concave cavity for the knife holder 4 to be placed. A connector 7 that cooperates with the knife holder 6 is provided in the center of the concave cavity. The connector 7 is fixedly connected to the output shaft of the motor 5. Four buckles 20 that are locked with the host 1 are provided at intervals on the outer periphery of the lower edge of the cup body 2.

[0021] The specific structures of the main machine 1, the knife holder 4 and the cup body 2 are similar to those in the prior art and will not be described in detail here.

[0022] The working principle is:

[0023] A pressure relief cylinder 31 and a pressure relief hole 35 are arranged on the pressure relief and explosion-proof cup cover 3. When the pressure in the cup body 2 is too high, the gas will be relieved through the pressure relief hole 35. The design of the pressure relief cylinder 31 acts as a retaining ring. In this way, during the rotation of the blade, the water flow will form a vortex, so that there is no water flow in the pressure relief cylinder 31, which is only used for pressure relief. The liquid in the cup body 2 will not splash out from the pressure relief hole 35, which effectively solves the problem of cup explosion caused by excessive pressure in the container during the preparation of hot drinks.

[0024] During installation, the pressure relief and explosion-proof cup cover 3 is installed on the cup body 2 by threaded rotation, and the cup body 2 is assembled and fixed with the knife holder 4 by rotation. The assembled cup assembly is placed on the main unit 1 and locked with the main unit 1 by the buckle 20 on the outside of the cup body 2.

[0025] During stirring, the motor 5 drives the connector 7 to drive the blade holder 6 to rotate at high speed for stirring to complete the hot drink making. The air pressure in the cup body 2 is released through the pressure relief hole 35 on the pressure relief and explosion-proof cup cover 3, thereby effectively solving the problem of cup explosion caused by excessive pressure in the container during hot drink making.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
