[0023] In the related art, mixers are often used in food processing to mix dough, stuffing, cream or egg liquid. In order to prevent foreign objects from falling into the mixing barrel during mixing, or to prevent people from accidentally touching the actuator during mixing, mixers on the market are often equipped with protective nets. Currently, most protective nets are folded open and closed or connected by snaps to achieve disassembly and assembly. The operation during disassembly and assembly is cumbersome, resulting in low disassembly and assembly efficiency during cleaning, affecting production efficiency.

[0024] To solve the above problems, refer to Figure 1 and Figure 2 In an embodiment of the first aspect of the present invention, a protective net disassembly and assembly structure is provided, including a fixing member 100 and a protective net 110. It can be understood that the fixing member 100 is a part of the mixer head, and a supporting surface 102 is provided on the outer peripheral wall of the fixing member 100. The protective net 110 is provided with a mounting portion 111 wrapped around the outer periphery of the fixing member 100, and a movable pin 121 and a plurality of fasteners 112 are provided on the mounting portion 111. The plurality of fasteners 112 are arranged at intervals along the circumference of the mounting portion 111. The supporting surface 102 is supported on the connecting end 131 of the movable pin 121 and the bottom wall of the fastener 112 to realize the installation of the protective net 110 on the fixing member 100. The movable pin 121 is moved to increase the distance between the connecting end 131 and any fastener 112, so that the protective net 110 can be detached from the fixing member 100.

[0025] It can be understood that the movable pin 121 can move in the radial direction of the fixing member 100. When the movable pin 121 moves, it can change the minimum distance between its nearest end to the central axis of the fixing member 100 and the wall surface of the fastener 112 close to the central axis of the fixing member 100, thereby realizing the installation and disassembly of the protective net 110 on the fixing member 100.

[0026] Specifically, refer to Figure 2 and Figure 3 The outer peripheral wall of the fixing member 100 is provided with a concave connection groove 101, and the support surface 102 is located in the connection groove 101. The support surface 102 contacts the bottom wall of the movable pin 121 and the fastener 112 to support the movable pin 121 and the fastener 112, so that the protective net 110 is installed on the fixing member 100. Furthermore, the connection groove 101 is arranged around the outer peripheral wall of the fixing member 100, so that the protective net 110 can rotate around the fixing member 100, thereby realizing the rotation opening and closing function of the protective net 110, which is conducive to improving the convenience of operation.

[0027] In some embodiments, a protruding convex edge is provided on the outer peripheral wall of the fixing member 100, and the support surface 102 is located on the upper surface of the convex edge. The support surface 102 contacts the bottom wall of the movable pin 121 and the fastener 112 to support the movable pin 121 and the fastener 112, so that the protective net 110 is installed on the fixing member 100. At the same time, the convex edge is arranged around the outer peripheral wall of the fixing member 100, so that the protective net 110 can rotate around the fixing member 100, thereby realizing the rotating opening and closing function of the protective net 110, which is conducive to improving the convenience of operation.

[0028] Reference Figure 4 and Figure 5 It can be understood that the mounting portion 111 includes a box body 120, a movable pin 121 and a locking piece 123. The box body 120 is fixedly mounted on the outer peripheral wall of the mounting portion 111 away from the fixing member 100, and the movable pin 121 and the locking piece 123 are both movably mounted in the box body 120.

[0029] Reference Figure 7 It can be understood that the movable pin 121 is provided with a limiting groove 122, and the locking piece 123 is provided with a limiting portion 125. When the movable pin 121 is inserted into the connecting groove 101, the limiting portion 125 is engaged in the limiting groove 122. The locking piece 123 can keep the movable pin 121 inserted into the connecting groove 101 and abut against the supporting surface 102, thereby realizing the installation of the protective net 110 on the fixing member 100. When the protective net 110 is disassembled, the limiting portion 125 can be disengaged from the limiting groove 122 when the locking piece 123 is pressed and moved radially along the movable pin 121, and the movable pin 121 can be separated from the contact with the supporting surface 102, thereby being separated from the connecting groove 101.

[0030] It can be understood that locking and unlocking can be achieved only by pressing the movable pin 121 and the locking plate 123. The action is simple, which makes the operation easy. Especially in the process of making food, the operator's hands are stained with water or oil. The pressing operation can effectively prevent the hands from slipping, thereby avoiding operation failure, which is conducive to improving production efficiency.

[0031] Reference Figure 4 and Figure 6 It can be understood that the mounting portion 111 is provided with a plurality of fasteners 112 that are buckled into the connecting groove 101. In the present embodiment, at least two fasteners 112 are provided. The two fasteners 112 and the movable pin 121 are simultaneously inserted into the connecting groove 101 and abut against the supporting surface 102, so that the protective net 110 can be installed on the mounting portion 111.

[0032] It can be understood that the fastener 112 is fixedly installed on the mounting portion 111 toward the inner wall of the fixing member 100, and the fastener 112 has a fastening portion 113 extending toward the connecting groove 101. At the same time, the fastening portion 113 extends along the circumference of the mounting portion 111, which can increase the contact area between the fastener 112 and the connecting groove 101, thereby improving the installation stability of the protective net 110 on the mounting portion 111.

[0033] In some embodiments, at least one fastener 112 is provided, and the fastener 112 extends along the circumference of the fixing member 100, and the central angle corresponding to the fastener 112 in the circumference of the fixing member 100 does not exceed 180°, so as to achieve stable fastening and smooth disassembly of the mounting portion 111 on the fixing member 100.

[0034] Reference Figure 3 It can be understood that the movable pin 121 can move in the radial direction of the fixing member 100, and the locking piece 123 can move in the radial direction of the movable pin 121. Further, the axial direction of the movable pin 121 is parallel to the radial direction of the fixing member 100, and the locking piece 123 moves in a direction perpendicular to the axial direction of the fixing member 100, which can be convenient for manual operation.

[0035] Reference Figure 5 It can be understood that a first elastic member 126 is provided at one end of the locking piece 123. When the movable pin 121 is inserted into the connecting groove 101, the first elastic member 126 can drive the locking piece 123 to move, and the limiting portion 125 is inserted into the limiting groove 122, so as to fix the movable pin 121. Further, an auxiliary rod 128 is provided at the other end of the locking piece 123 facing away from the first elastic member 126. The auxiliary rod 128 protrudes from the outside of the box body 120, which is convenient for manual operation. Further, a guide column 130 is provided at one end of the locking piece 123 provided with the first elastic member 126. The first elastic member 126 adopts a coil spring. The two ends of the first elastic member 126 press the locking piece 123 and the inner wall of the box body 120 respectively. The guide column 130 is inserted into the first elastic member 126, which can guide the movement of the locking piece 123 and improve stability.

[0036] It is understandable that a second elastic member 127 is provided between the movable pin 121 and the mounting portion 111, and the second elastic member 127 is a coil spring. At the same time, a fixed stopper 129 is provided on the movable pin 121, and the two ends of the second elastic member 127 press the stopper 129 and the inner wall of the box body 120 respectively to achieve the reset effect of the movable pin 121.

[0037] Reference Figure 7It can be understood that the movable pin 121 is provided with a through hole 124, and the movable pin 121 is inserted into the through hole 124. The minimum inner diameter of the through hole 124 is greater than the maximum outer diameter of the movable pin 121, so as to ensure that the movable pin 121 moves in the through hole 124. Further, the through hole 124 is a slot-shaped hole, and the through hole 124 extends along the circumferential direction of the fixing member 100, and the limiting portion 125 is located on one side of the through hole 124 close to the first elastic member 126, and the limiting portion 125 extends from the inner wall of the through hole 124 toward the movable pin 121.

[0038] It is understandable that when the protective net 110 is installed, the movable pin 121 is pressed and inserted into the connection groove 101, when the limiting groove 122 corresponds to the limiting portion 125, the first elastic member 126 is reset and can push the locking piece 123 to move, and the limiting portion 125 is inserted into the limiting groove 122, thereby preventing the movable pin 121 from escaping from the connection groove 101, and realizing the installation connection of the protective net 110 on the fixing member 100. When the protective net 110 is disassembled, the auxiliary rod 128 is pressed, and the locking piece 123 moves toward the first elastic member 126 along the radial direction of the movable pin 121, and the limiting portion 125 is escaping from the limiting groove 122, and the second elastic member 127 is reset and pushes the movable pin 121 to move in the direction away from the fixing member 100, and the movable pin 121 is escaping from the connection groove 101.

[0039] It is understandable that the minimum diameter of the radial inner wall of the mounting portion 111 is greater than the maximum diameter of the outer peripheral wall of the fixing member 100, so that there is a gap between the mounting portion 111 and the fixing member 100. When the movable pin 121 is disengaged from the connecting groove 101, the buckle portion 113 can be disengaged from the connecting groove 101, thereby realizing the disassembly process of the protective net 110.

[0040] In some embodiments, the limiting groove 122 is arranged around the outer peripheral wall of the movable pin 121, and two limiting portions 125 are provided in the through hole 124. The two limiting portions 125 are respectively located on the inner walls on both sides of the through hole 124 and on the radial sides of the movable pin 121. At the same time, the minimum distance between the two limiting portions 125 is smaller than the maximum diameter of the movable pin 121 to ensure that the limiting portion 125 can limit the movable pin 121.

[0041] According to an embodiment of the second aspect of the present invention, a mixer is provided, comprising the above-mentioned protective net disassembly structure. It can be understood that the mixer has all the technical features of the protective net disassembly structure, and therefore the mixer also has all the beneficial effects of the protective net disassembly structure.

[0042] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
