Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a mixer with a safety device. Background Art

[0002] Existing tea shops usually use automatic blenders to mix liquids to make foaming drinks. Such blenders usually include a blending cup and a base. When in use, the liquid to be processed is poured into the cup, and then the cup is placed on the base, and then the switch is turned on to complete the automatic mixing. However, when the staff takes out the cup to hold the liquid to be mixed, the top of the base is in a bare state. If the main control module on the base is accidentally touched and accidentally started, it will cause the starting drive mechanism to rotate, which may result in accidental injury to the staff. The equipment has safety issues. Moreover, when the staff encounters this situation, they may be in a panic, resulting in disruption of the work process. Therefore, the above problems need to be improved. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the present invention proposes a blender with a safety device, which can strengthen the connection between the cup body and the base and ensure that the device can only start working when they are connected.

[0013] The present invention provides an electromagnetic switch on the base, which is electrically connected to the main control module. A magnet that cooperates with the electromagnetic switch is provided at the bottom of the first connecting member. When the cup is located above the base, the magnet connects to the electromagnetic switch. Only when the magnet connects to the electromagnetic switch does the main control module provide electrical power to the electromagnetic switch, so that when the electromagnetic switch is energized, it has a strong attraction force and is attracted to the magnet, allowing the cup to be firmly placed on the base. Furthermore, only after the electromagnetic switch is attracted to the magnet can the drive mechanism start to operate, driving the stirring blade in the cup. This function avoids the problem of accidental startup of the blender causing harm to the staff. In other words, the arrangement of the electromagnetic switch and the magnet ensures that the drive mechanism in the base only starts to operate when the cup is located on the base, providing a good safety protection function. When the blending work is completed, when the cup needs to be removed for pouring liquid or cleaning, it is only necessary to apply a certain external force to remove the cup, so that the magnet and the electromagnetic switch are separated and the power is turned off.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1 to 3 , an embodiment of the present utility model discloses a blender with a safety device, including a cup body 1, a base 2, a driving mechanism 3 and a main control module (not shown in the figure), wherein the cup body 1 is provided with a stirring blade 4, the driving mechanism 3 is connected to the main control module and both are arranged in the base 2, and the driving mechanism 3 is used to drive the stirring blade 4 to rotate in the cup body 1; a first connecting member 5 is provided on the bottom surface of the cup body 1 extending downward, and the first connecting member 5 and the base 2 are provided with a connecting module that cooperates with each other, and the cup body 1 is connected to the base 2 through the connecting module; an electromagnetic switch 21 is provided on the base 2, and the electromagnetic switch 21 is electrically connected to the main control module; a magnet 51 is provided at the bottom of the first connecting member 5 that cooperates with the electromagnetic switch 21, and when the cup body 1 is located above the base 2, the magnet 51 is connected to the electromagnetic switch 21.

[0021] When the present invention is used, the liquid to be stirred is poured into the cup body 1, and the cup body 1 is then placed on the base 2. During this process, the cup body 1 is connected to the base 2 via the connection module on the first connection member 5, fixing its position on the base 2. The driving mechanism 3 is then activated by the main control module to drive the stirring blade 4 to rotate in the cup body 1, completing the work of stirring the liquid. When the staff takes out the cup body 1 to hold the liquid to be stirred, the top of the base 2 is in a bare state. If the main control module on the base 2 is accidentally touched and accidentally activated, the driving mechanism 3 will be activated and rotated, which may result in accidental injury to the staff. The equipment has safety issues in use. Moreover, when the staff encounters this situation, they may be in a panic, resulting in disruption of the work process.

[0022] To solve this problem, the utility model provides an electromagnetic switch 21 on the base 2, and the electromagnetic switch 21 is electrically connected to the main control module. A magnet 51 that cooperates with the electromagnetic switch 21 is provided at the bottom of the first connecting member 5. When the cup body 1 is located above the base 2, the magnet 51 is connected to the electromagnetic switch 21. Only when the magnet 51 is connected to the electromagnetic switch 21 can the main control module provide electrical power to the electromagnetic switch 21, so that the electromagnetic switch 21 has a strong attraction when it is energized and is adsorbed by the magnet 51, so that the cup body 1 can be firmly placed on the base 2; and, after the electromagnetic switch 21 is adsorbed and connected to the magnet 51, the driving mechanism 3 can start working to drive the stirring blade 4 in the cup body 1. This function avoids the problem of accidental startup of the blender causing harm to the staff. That is, through the setting of the electromagnetic switch 21 and the magnet 51, it is ensured that the driving mechanism 3 in the base 2 can start working only when the cup body 1 is located on the base 2, which has a better safety protection function; and when the stirring work is completed, when the cup body 1 needs to be removed for pouring liquid or cleaning, it is only necessary to apply a certain external force to remove the cup body 1, so that the magnet 51 is separated from the electromagnetic switch 21 and the power is cut off.

[0023] Furthermore, the first connecting member 5 is integrally formed with the bottom of the cup body 1 , which can improve the stability when the cup body 1 is connected to the base 2 .

[0024] Furthermore, the first connecting member 5 is detachably connected to the bottom of the cup body 1, which is convenient for installing or removing parts provided on the bottom of the cup body 1 and is also convenient for cleaning and maintenance of the machine.

[0025] See also Figure 3The upper part of the base 2 is provided with a recessed portion 22 for accommodating the first connecting member 5. The first connecting member 5 is connected and fixed to the inner side of the recessed portion 22; the electromagnetic switch 21 is provided on the recessed portion 22. When in use, the first connecting member 5 of the cup body 1 is aligned and placed on the recessed portion 22 of the base 2, and then the cup body 1 is rotated to complete the work of stably connecting the cup body 1 to the base 2. In this process, the staff only needs to align and place one set of parts, and this structure also makes it convenient for the staff to quickly align the structure of the bottom of the cup body 1 and the recessed portion 22 of the base 2. When the electromagnetic switch 21 provided on the recessed portion 22 contacts and connects with the magnet 51 at the bottom of the first connecting member 5, it can strengthen the connection between the cup body 1 and the base 2, improve its connection stability, and prevent the device from starting by mistake.

[0026] Furthermore, at least one first thread 52 is provided on the outer side of the first connecting member 5; a second thread 23 is provided on the inner side of the recessed portion 22 to match the first thread 52, and the cup body 1 and the base 2 are connected via the first thread 52 and the second thread 23. During use, the cup body 1 is connected via the first thread 52 on the outer side of the first connecting member 5 and the second thread 23 on the inner side of the recessed portion 22 of the base 2, thereby improving the stability of the connection between the cup body 1 and the base 2.

[0027] As a preferred embodiment, the connection relationship between the first connecting member 5 and the base 2 can also be the following structure: further, the bottom of the first connecting member 5 is provided with a plurality of first protrusions 53 / first grooves 54, and the top of the base 2 is provided with a second groove 24 / second protrusion 25 that cooperates with the first protrusions 53 / first grooves 54. When the cup body 1 is positioned above the base 2, the first protrusions 53 and the second grooves 24 / the first groove 54 and the second protrusions 25 are connected and fixed; the electromagnetic switch 21 is provided on the second groove 24 or the second protrusion 25, and the magnet 51 is correspondingly provided on the first protrusion 53 or the first groove 54. The position of the electromagnetic switch 21 on the base 2 cooperates with the position of the magnet 51 on the bottom of the first connecting member 5, so that when the cup body 1 is positioned on the base 2, the two can be in contact and connected.

[0028] Furthermore, the output shaft 31 of the driving mechanism 3 extends out of the top surface of the base 2, and a rotating shaft 6 and a bearing 7 are provided in the middle of the inner side of the bottom of the cup body 1. The stirring blade 4 is provided on the top of the rotating shaft 6, and the rotating shaft 6 is fixed to the bottom of the cup body 1 through the bearing 7. The other end of the rotating shaft 6 relative to the stirring blade 4 passes through the bottom of the cup body 1 and the first connecting member 5 in sequence, and is connected to the output shaft 31.

[0029] Specifically, the bearing 7 is provided between the rotating shaft 6 and the bottom of the cup body 1 , and is used to fix the position of the rotating shaft 6 on the bottom of the cup body 1 , thereby preventing the rotating shaft 6 from tilting and collapsing during rotation.

[0030] Specifically, the stirring blade 4 is entirely located inside the cup body 1, with the center of the stirring blade 4 located at the top of the rotating shaft 6. By connecting the rotating shaft 6 to the output shaft 31, the rotation of the output shaft 31 can simultaneously drive the rotating shaft 6 to rotate, thereby driving the stirring blade 4 to rotate, thereby stirring the liquid in the cup body 1 and completing the stirring operation. The rotating shaft 6 passes through the bottom of the cup body 1 and the first connecting member 5 in sequence before connecting to the output shaft 31. On the one hand, the first connecting member 5 does not hinder the connection between the rotating shaft 6 and the output shaft 31, and on the other hand, it can prevent foreign matter from interfering with the connection between the two, thereby eliminating the effect of the output shaft 31 and the rotating shaft 6 being unable to connect and work.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
