Description

Technical Field

[0001] This utility model relates to the field of mixer technology, and in particular to a multi-functional mixer with a detachable head. Background Technology

[0002] With the development of household kitchen appliances, mixers, as a common food processing equipment, are widely used in homes. A mixer is a kitchen appliance used to mix, stir, or grind different ingredients. It achieves uniform mixing, emulsification, crushing, or fine processing by using rotating stirring parts to mechanically act on the ingredients in the container.

[0003] In existing multi-functional mixers, the mixer head and the mixer body are usually fixedly connected, which makes the operation complicated when cleaning, maintenance or replacement of the mixer head is required. Users need to disassemble the whole machine, which is time-consuming and can easily cause wear and tear on the parts. In addition, the installation process is prone to misalignment, which may even lead to safety hazards. Utility Model Content

[0037] The present invention will be further described below with reference to the accompanying drawings.

[0038] like Figures 1 to 6As shown, this utility model provides a multi-functional mixer with a detachable head, including a mixer body 1 and a head assembly 2. The head assembly 2 is detachably connected to the mixer body 1 to achieve a modular structure design. The head assembly 2 is provided with a mounting protrusion 24. The mixer body 1 is provided with a plug groove 111 for the mounting protrusion 24 to be inserted. When the mounting protrusion 24 and the plug groove 111 are plugged in, the mixer body 1 and the head assembly 2 are electrically connected. The plug groove 111 is provided with a female head 112, and the mounting protrusion 24 is provided with a male head 241. The male head 241 and the female head 112 are plugged in to make the mixer body 1 and the head assembly 2 electrically connected. This ensures the precise alignment of the male head 241 and the female head 112 during the plugging process, avoids poor contact due to misalignment, and improves the reliability of the electrical connection. Several abutment ribs 142 are formed on the outer periphery of the mounting protrusion 24, and the abutment ribs 142 are arranged at intervals along the outer contour of the mounting protrusion 24. Improve structural strength to prevent loosening or deformation due to stress after prolonged use, thereby extending the service life of the entire machine.

[0039] The head assembly 2 includes a head housing 21, a drive unit 22, and a connector assembly 23. The drive unit 22 is installed inside the head housing 21 to provide rotational power and transmits the power to the mixing unit inside the mixer body 1 through the connector assembly 23. The mixing unit includes a mixing shaft 14 and a blade shaft 15. The mixing shaft 14 and the blade shaft 15 can be selected for installation according to usage requirements. The connector assembly 23 is located at one end of the head housing 21 and is used to connect to the mixing unit of the mixer body 1. A male connector 241 is provided at the end of the head housing 21 away from the connector assembly 23. The male connector 241 is connected to the female connector 112 on the mixer body 1 to achieve electrical connection, ensuring that the head assembly 2 can be quickly powered on after installation without additional wiring operations.

[0040] like Figures 2 to 5 As shown, the mixer body 1 includes a base 11, a mixing container 12, and a cover 13. The mixing container 12 is mounted on the base 11, and the cover 13 covers the upper end of the mixing container 12. The cover 13 is provided with a mounting groove 131. The head assembly 2 is positioned and fixed by inserting a mounting protrusion 25 into the mounting groove 131. The mounting protrusion 25 and the mounting groove 131 are interlocked, which enables the head assembly 2 to be quickly assembled and disassembled, ensuring accurate positioning and avoiding loose connections due to deviation.

[0041] The inner wall of the mounting groove 131 is provided with a positioning protrusion 1311, and the mounting protrusion 25 is provided with a corresponding positioning groove 251. The two are interlocked to achieve accurate positioning of the head assembly 2. The mounting groove 131 is also provided with a positioning protrusion 1312, and the mounting protrusion 25 is provided with a positioning groove 252. The positioning protrusion 1312 and the positioning groove 252 are engaged to confirm the installation depth and angle, ensuring that the head assembly 2 is installed in the correct position. To further improve safety performance, a micro switch 253 is provided on the positioning groove 252. The micro switch 253 can detect the installation status of the head assembly 2 and is linked to the control circuit. When it is not installed correctly, the power is cut off to prevent misoperation and dry running, thereby improving the safety of use.

[0042] like Figure 7 and Figure 8 As shown, the connector assembly 23 includes an inner connector 231 and an outer connector 232 sleeved on its outer side. The inner connector 231 and the outer connector 232 rotate synchronously and are used to connect different working parts. The outer connector 232 is used to install the stirring shaft 14, and the inner connector 231 is used to install the blade shaft 15. Users can select the stirring or cutting mode according to different processing needs to achieve function switching and enhance the versatility of the equipment. The blade shaft 15 is provided with a spline rod 151, and the inner connector 231 is provided with a spline groove 2311. The two are plugged in to achieve stable torque transmission and avoid slippage. At the same time, it is easy to disassemble and improve the convenience of maintenance. The stirring shaft 14 and the outer connector 232 are precisely connected through a guide fit structure. The outer connector 232 is provided with an upper guide block 2321, and the stirring shaft 14 is provided with a lower guide block 141. A guide groove is formed between adjacent lower guide blocks 141. The upper guide block 2321 is plugged in with the guide groove to ensure accurate assembly alignment and improve operational stability.

[0043] The basic working principle of this utility model is as follows: The user connects the head assembly 2 to the mixer body 1. First, the mounting protrusion 25 on the head housing 21 is inserted into the mounting groove 131 on the cover 13 of the mixer body 1. During the insertion process, the positioning protrusion 1311 and the positioning groove 251 cooperate with each other, and the positioning protrusion 1312 and the positioning groove 252 further cooperate to ensure that the head assembly 2 reaches the predetermined installation depth. During the installation process, the mounting protrusion 24 is gradually inserted into the insertion groove 111 on the base 11, and the male head 241 and the female head 112 are inserted synchronously to achieve electrical connection and micro-motion. After detecting that the head assembly 2 is fully in place, switch 253 closes the control circuit, allowing the drive unit 22 to receive power input. When the drive unit 22 starts, its output rotational power is transmitted to the connector assembly 23 through the transmission structure inside the head housing 21. When the user installs the stirring shaft 14, the stirring shaft 14 is engaged with the outer connector 232 through the guide block and guide groove, and is driven by the drive unit 22 to complete the stirring action. When the user installs the blade shaft 15, the splined rod 151 of the blade shaft 15 is engaged with the splined groove 2311 of the inner connector 231 to achieve the rotary cutting function. After the work is completed, the user can disconnect the power and disassemble the head assembly 2 without additional tools, facilitating cleaning and subsequent use.

[0044] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
