[0032] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0033] Reference Figure 1 In an embodiment of the utility model, a lifting structure of a mixer includes a body 100, a transmission assembly 110 and a power assembly 120. The body 100 is provided with a container 101 that can be lifted and slid. The transmission assembly 110 includes a support seat 111 and a guide member 112. The container 101 is installed on the support seat 111, and the support seat 111 is slidably connected to the side wall of the body 100. Guide parts 114 are provided on both sides of the support seat 111. The guide member 112 has a guide groove 113 with a V-shaped cross-section. The guide part 114 is inserted into the guide groove 113 and can slide along the length direction of the guide member 112. The guide member 112 can limit the freedom of the support seat 111 in the horizontal direction through the guide groove 113 with a V-shaped cross-section, and realize the lifting and lowering guidance of the support seat 111 and the container 101, so that the structure is stable. It can be understood that during installation, the guide part 114 of the support seat 111 can be inserted into the guide groove 113 from top to bottom or from bottom to top, and the installation is simple and quick. The power assembly 120 is installed in the body 100, and the power assembly 120 includes a screw rod 121, a nut 122 and a driving motor 123. The screw rod 121 is rotatably connected to the body 100, and the nut 122 is fixed to the support seat 111. When the driving motor 123 drives the screw rod 121 to rotate, the nut 122 can drive the container 101 to move up and down. The transmission method through the screw rod 121 is conducive to improving the stability of the container 101 during the lifting and lowering movement, thereby improving the user experience.

[0034] Specifically, along the width direction of the body 100, the guide members 112 are arranged on both sides of the support seat 111, and the open part of the guide groove 113 faces the support seat 111, so that the support seat 111 and the container 101 are located between the two guide members 112, which can realize a good limiting function for the support seat 111. Figure 2The guide groove 113 includes a first mating surface 115 and a second mating surface 116. There is an angle between the first mating surface 115 and the second mating surface 116, and the angle is no greater than 90°, so that the guide groove 113 presents a V-shaped cross-section, which can effectively prevent the guide portion 114 from escaping from either side of the guide groove 113. Furthermore, a transition groove 117 is provided between the first mating surface 115 and the second mating surface 116. The transition groove 117 is located at the bottom of the guide groove 113 and is recessed inwardly. It can be understood that, on the one hand, when the guide portion 114 is inserted into the guide groove 113, the two side walls of the guide portion 114 respectively cooperate with the first mating surface 115 and the second mating surface 116, and the end of the guide portion 114 is easy to interfere with the bottom of the guide groove 113. Therefore, the provision of the transition groove 117 can avoid interference, thereby ensuring that the side wall of the guide portion 114 and the side wall of the guide groove 113 produce stable pressure contact and ensure the stability of sliding; on the other hand, in the process of machining and forming the guide groove 113, the angle between the first mating surface 115 and the second mating surface 116 is difficult to machine, and the angle does not need to be matched in actual use. Therefore, by providing the transition groove 117, a buffer space for processing tools such as cutting tools can be reserved, making the process more reasonable and conducive to improving machining efficiency.

[0035] Furthermore, a positioning platform 104 is provided on the side wall of the machine body 100 on which the guide member 112 is installed, and is protruding toward the direction of the container 101. The positioning platform 104 is provided with a positioning surface 105, and the positioning surface 105 abuts against the side wall of the guide member 112 facing the container 101, which helps to quickly position the guide member 112 during installation, thereby ensuring that the container 101 slides along a preset direction. Furthermore, a limiting rod 106 is installed on the side wall of the machine body 100 on which the guide member 112 is installed, and when the support seat 111 rises to a preset position, it can abut against the end of the limiting rod 106, thereby realizing the travel limit of the container 101 on the machine body 100.

[0036] Reference Figure 3 and Figure 4 The body 100 has a chamber 102, and a mounting seat 103 is provided on the inner wall of the chamber 102. Mounting plates 124 are provided at both ends of the screw rod 121. The mounting plates 124 are detachably mounted on the mounting seats 103. It can be understood that a bearing is provided in the mounting plate 124 and is sleeved on the screw rod 121. The screw rod 121 is rotatably connected to the mounting plate 124 through the bearing. It can be understood that the contact surface between the mounting plate 124 and the mounting seat 103 is perpendicular to the rotation axis of the screw rod 121. During the installation process, the mounting plate 124 and the screw rod 121 are pre-installed as one body, and then the screw rod 121 is installed in the body 100 through the connection between the mounting plate 124 and the mounting seat 103, which can achieve rapid positioning and enable the power component 120 to be installed in the body 100 in an integrated manner, which helps to improve the installation efficiency.

[0037] Further, refer to Figure 5 A plurality of sensors 107 are provided in the chamber 102, and at least two sensors 107 located at different heights are provided on one side of the screw rod 121, and a sensing sheet 128 is provided on the nut 122. The sensor 107 can detect the sensing sheet 128, so as to realize the lifting and lowering stroke limit of the nut 122 by the sensor 107. When the nut 122 moves to the upper part and the sensing sheet 128 senses the upper sensor 107, the container 101 reaches the upper dead point. When the nut 122 moves to the lower part and the sensing sheet 128 senses the lower sensor 107, the container 101 reaches the lower dead point, which can effectively prevent the container 101 from exceeding the stroke and causing a collision when moving.

[0038] Reference Figure 4 , a motor seat 125 is also provided in the chamber 102, and the drive motor 123 is installed in the motor seat 125. At the same time, a connecting column 129 is provided between the motor seat 125 and the body 100. The connecting column 129, the motor seat 125 and the body 100 are fixed by bolts. The connecting column 129 makes the motor seat 125 located on the side of the screw rod 121 away from the body 100, which can improve the compactness of the spatial layout. Furthermore, a sprocket 127 is provided on both the drive motor 123 and the screw rod 121. The sprocket 127 is located at the upper end of the screw rod 121. A transmission chain is provided between the drive motor 123 and the screw rod 121. The drive motor 123 can drive the screw rod 121 to rotate through the transmission chain, which can achieve an accurate and stable transmission function.

[0039] The embodiments of the present invention are described in detail above in conjunction with 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.
