Description

Technical Field

[0001] This utility model relates to the field of food processing equipment, specifically to a mixer. Background Technology

[0002] A mixer is a convenient kitchen tool used in daily life for mixing. It is often used to beat egg whites and yolks into a smooth egg mixture, or to beat egg whites and yolks separately until foamy.

[0003] However, current manual mixers on the market have limited functions, only capable of beating and whipping eggs, and cannot be used to beat other foods, such as potatoes and garlic, thus failing to meet people's daily needs. Therefore, it is necessary to invent a mixer suitable for mixing a variety of foods. Utility Model Content

[0004] The purpose of this invention is to provide a stirrer that solves the problem of limited functionality in existing stirrers.

[0005] To achieve the purpose of this utility model, a stirrer is provided, including a connecting rod, a handle, and stirring bars. The stirring bars are disposed at one end of the connecting rod, and the handle is disposed at the other end of the connecting rod. The stirring bars are made of metal and have serrations arranged along the length of the stirring bars. There are multiple stirring bars arranged circumferentially along the connecting rod. The stirrer also includes a blade fixing member, which is fixedly sleeved on the side of the connecting rod away from the handle. The blade fixing member is located within the space enclosed by the multiple stirring bars, and at least one blade is arranged circumferentially on the blade fixing member. The blade is made of metal.

[0006] As can be seen from the above design, the mixing strip is made of metal, making it stronger and sharper. This allows the mixer to not only beat eggs but also mash potatoes, garlic, cream, onions, and other ingredients. The added serrations improve gripping and cutting force, enabling faster food blending. The added blades enhance the mixer's cutting ability, breaking down food more quickly and evenly. Furthermore, the blades are concealed within the mixing strip, minimizing user contact and ensuring safer use, while also preventing damage to the container during blending. By using a metal mixing strip and adding serrations and blades, the mixer's versatility is broadened, making it more versatile and meeting the needs of everyday users.

[0007] A further embodiment includes a mounting head and a locking device. A connecting rod passes through the mounting head, and the mounting head is fixed to the connecting rod. A locking device is provided on the side of the mounting head near the handle. The connecting rod passes through the locking device, and the locking device can move along the length of the connecting rod. A receiving cavity is provided on the side of the blade holder away from the handle, and the mounting head is fixed in the receiving cavity. One end of the stirring bar is inserted circumferentially into the side of the mounting head away from the handle and fixed, and the other end of the stirring bar is inserted circumferentially into the side of the locking device near the mounting head and fixed.

[0008] As can be seen from the above scheme, the size of the stirring bar can be changed when the firmware is set, which improves the stirring effect.

[0009] A further option is that the locking device includes a knob and a moving head, with the moving head closer to the mounting head than the knob. A fixing head is provided on the side of the moving head closest to the mounting head, and the stirring bar is fixed inside the fixing head.

[0010] As can be seen from the above solution, the knob design allows the mixer to achieve a fastening effect without additional external parts, making it easier to adjust the mixing bar with one hand, while also making the appearance more aesthetically pleasing.

[0011] A further design involves a moving head with a fastening protrusion and an external thread, the fastening protrusion being closer to the handle than the fixed head; a knob is fitted over the fastening protrusion and has an internal thread that matches the external thread.

[0012] A further option is to have multiple fastening protrusions, which are arranged circumferentially along the connecting rod and extend along the length of the connecting rod, and the fastening protrusions are elastic elements.

[0013] As can be seen from the above scheme, when the knob is fully tightened, the fastening protrusion is in close contact with the outer surface of the connecting rod, thus fixing the fastener; when the knob is loosened, there is a gap between the fastening protrusion and the outer surface of the connecting rod, which allows the fastener to move along the irregular connecting rod. The above structure is simple and has stable performance.

[0014] A further option is to have mounting holes along the circumference of the mounting head, into which the stirring strip is inserted and fixed.

[0015] As can be seen from the above scheme, the setting of the mounting holes ensures the stability of the mixing strip installation, and the mixing strip can achieve a good fixing effect.

[0016] A further embodiment is that a fixed sleeve is fitted on the side of the connecting rod away from the stirring bar, a movable sleeve is placed on the axis of the fixed sleeve, the connecting rod extends into the movable sleeve, an inner handle is provided on the outside of the movable sleeve, and the inner handle is connected to the fixed sleeve; a threaded first protrusion is provided on the inner wall of the inner handle, and multiple second protrusions are provided on the outer wall of the movable sleeve along the circumference, the second protrusions contact the inner wall of the inner handle where the first protrusion is not provided, and an elastic member is provided on the outer sleeve of the movable sleeve, the other end of the elastic member away from the movable sleeve abuts against the inner bottom wall of the inner handle.

[0017] A further design includes an outer handle, which is fitted over the inner handle and is made of silicone.

[0018] As can be seen from the above scheme, when the handle is pressed, the connecting rod drives the moving sleeve to penetrate deeper into the inner handle. Because the moving sleeve has a second protrusion, when the second protrusion moves to the position where the first protrusion is located, it is blocked and rotates. The moving sleeve drives the connecting rod to rotate, thereby causing the mounting head, stirring bar, blade holder, and locking fastener to rotate as a whole. When no pressure is applied, the moving sleeve drives the connecting rod to return to its original position under the action of the elastic component. Multiple presses of the handle can automatically break up food without manual rotation, making it more labor-saving, convenient, and with higher stirring efficiency.

[0019] A further option is to use an irregularly shaped link with a polygonal cross-section.

[0020] As can be seen from the above scheme, the irregular connecting rod plays a guiding role in the movement of the locking device, preventing the stirring bar from rotating during the movement of the locking device. This ensures that the stirring bar only moves longitudinally and does not rotate axially, thus guaranteeing the stirring effect and the service life of the stirring bar. All of the above operations can be performed with one hand, making it more convenient to use.

[0021] A further design includes an anti-slip pad for the mixer, with one end of the connecting rod containing the stirring bar inserted into the anti-slip pad.

[0022] As can be seen from the above solution, the anti-slip mat prevents slipping, ensures stability during rotation, and avoids damage to the container during stirring. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0029] See Figures 1 to 5 The mixer provided by this utility model includes a connecting rod 1, a mounting head 2, a stirring bar 3, a locking fastener 4, a handle 5, an anti-slip pad 6, and a blade fixing component 7. Preferably, the anti-slip pad 6 is made of silicone.

[0030] In this embodiment, the connecting rod 1 is an irregularly shaped connecting rod, and the cross-section of the irregularly shaped connecting rod 1 is a polygonal structure, including triangles. Specifically, in this embodiment, the cross-section of the irregularly shaped connecting rod 1 is a hexagon.

[0031] The mounting head 2, stirring bar 3, locking fastener 4, and anti-slip pad 6 are located at one end of the connecting rod 1 along its length, and the handle 5 is located at the other end of the connecting rod 1 along its length. The mounting head 2 has a through hole 22 through which the connecting rod 1 passes, securing the mounting head 2 to the connecting rod 1. The locking fastener 4 is located on the side of the mounting head 2 closest to the handle 5, through which the connecting rod 1 passes, and the locking fastener 4 can move along the length of the connecting rod 1. The anti-slip pad 6 is located on the side of the mounting head 2 furthest from the handle 5. One end of the connecting rod 1 with the stirring bar 3 is inserted into the anti-slip pad 6 but does not pass through it. The other end of the connecting rod 1 is inserted into the handle 5 but does not pass through it.

[0032] The stirring bar 3 is made of metal and has serrations 31 arranged along the length of the stirring bar 3.

[0033] There are multiple stirring bars 3. Multiple stirring bars 3 are fixedly sleeved with blade fixing parts 7 along the circumference of the connecting rod 1 on the side of the connecting rod 1 away from the handle 5. The blade fixing parts 7 are located in the space 32 enclosed by multiple stirring bars 3. The blade fixing parts 7 are provided with at least one blade 71 along the circumference. The blade 71 is made of metal.

[0034] The blade holder 7 has a receiving cavity 72 on the side away from the handle 5, and the mounting head 2 is fixed in the receiving cavity 72. The mounting head 2 has a mounting hole 71 along the circumferential direction. One end of the stirring bar 3 is inserted into the mounting hole 71 from the side of the mounting head 2 away from the handle 5 and fixed. The other end of the stirring bar 3 is inserted into the locking fastener 4 along the circumferential direction near the side of the mounting head 2 and fixed.

[0035] The locking device 4 includes a knob 41 and a moving head 42. The moving head 42 is closer to the mounting head 2 than the knob 41. A fixing head 423 is provided on the side of the moving head 42 that is closer to the mounting head 2, and the stirring bar 3 is fixed in the fixing head 423.

[0036] Specifically, the moving head 42 is provided with an external thread 421 and a fastening protrusion 422, with the fastening protrusion 422 closer to the handle 5 than the fixed head 423. A knob 41 is sleeved around the fastening protrusion 422 and is provided with an internal thread (not shown in the figure), which matches the external thread 421. There are multiple fastening protrusions 422, which are arranged circumferentially along the connecting rod 1 and extend along the length of the connecting rod 1, and are elastic elements. In this embodiment, the connecting rod 1 is an irregularly shaped connecting rod, and the number of fastening protrusions 422 is the same as the number of sidewalls of the irregularly shaped connecting rod 1. In this embodiment, there are six fastening protrusions 422, each corresponding to a different face of the irregularly shaped connecting rod 1. The knob 41 is provided with a frustum end, located on the side of the knob away from the mounting head 2.

[0037] When knob 41 is fully tightened, the fastening protrusion 422 is pressed tightly against the outer surface of connecting rod 1, thus securing the locking device 4. When knob 41 is loosened, a gap exists between the fastening protrusion 422 and the outer surface of connecting rod 1, allowing the locking device 4 to move along connecting rod 1. The connecting rod 1 is designed to prevent knob 41 from rotating simultaneously with the moving head 42, thus preventing the stirring bar 3 from being rotated as well. It also prevents the stirring bar 3 from rotating during the movement of the locking device 4, guiding the movement of the locking device 4 and ensuring the stirring effect and the service life of the stirring bar 3. Both the rotation and movement operations of knob 41 can be performed with one hand to adjust the stirring bar 3, and only longitudinal movement occurs, without axial rotation. After adjustment, it can also be tightened with one hand, without the need for additional external parts for fastening, making it more convenient to use and more aesthetically pleasing.

[0038] The handle 5 includes an outer handle 51, an inner handle 52, a fixed sleeve 53, a movable sleeve 54, and an elastic component 55. The fixed sleeve 53 is fitted onto the side of the connecting rod 1 away from the stirring bar 3. The movable sleeve 54 is positioned on the axis of the fixed sleeve 53, and the connecting rod 1 extends into the movable sleeve 54 and abuts against the inner wall of the movable sleeve 54. The inner handle 52 is provided outside the movable sleeve 54 and is connected to the fixed sleeve 53. The outer handle 51 is fitted over the inner handle 52. Preferably, the outer handle 51 is made of silicone. In this embodiment, the elastic component 55 is a helical spring.

[0039] The inner wall of the inner handle 52 is provided with a threaded first protrusion 521, and the outer wall of the movable sleeve 54 is provided with a plurality of second protrusions 541 along the circumference. The second protrusions 541 contact the inner wall of the inner handle 52 where the first protrusions 521 are not provided. The movable sleeve 54 is covered with an elastic member 55, and the other end of the elastic member 55 away from the movable sleeve 54 abuts against the inner bottom wall of the inner handle 52.

[0040] When handle 5 is pressed, connecting rod 1 causes movable sleeve 54 to penetrate deeper into inner handle 52. Since a second protrusion 541 is provided on the outside of movable sleeve 54, when the second protrusion 541 moves to the position where the first protrusion 521 is located, it is blocked and rotates. Movable sleeve 54 drives connecting rod 1 to rotate, thereby causing the mounting head 2, stirring bar 3, locking fastener 4, anti-slip pad 6, and blade fixing member 7 to rotate as a whole. When no pressure is applied, under the action of elastic member 55, movable sleeve 54 drives connecting rod 1 to return to its original position. Multiple presses of handle 5 can automatically break up food without manual rotation, making it more labor-saving, convenient, and with higher stirring efficiency.

[0041] In this embodiment, the mixing bar 3 is made of metal, making it stronger and sharper. This allows the mixer to not only beat eggs but also mash potatoes, garlic, cream, onions, and other ingredients. The addition of serrated teeth 31 improves gripping and cutting force, enabling faster food mixing. The addition of blades 71 enhances the mixer's cutting ability, allowing for faster and more even food blending. Furthermore, the blades 71 are located within the mixing bar 3, minimizing user contact and ensuring safer use, while also preventing damage to the container during mixing. By using metal for the mixing bar 3 and incorporating serrated teeth 31 and blades 71, the mixer's versatility is broadened, making it more functional and meeting the needs of everyday users.
