Abstract
Description
Technical Field
[0001] This utility model relates to the field of household appliances, and in particular to a mixer. Background Technology
[0002] A blender is a multi-functional machine that can make soy milk, grind dry powder, juice, mince meat, and shaved ice, making it an indispensable household appliance in the kitchen.
[0003] Currently, most blenders on the market are operated by placing the cup on the base and pressing a button to start the motor and blades, regardless of whether the lid is closed. While this design is convenient and easy to use, the fact that it can be started regardless of whether the lid is closed often leads to accidents where people put their hands into the blender while it's running and get cut by the high-speed rotating blades. These accidents are more common among active and curious young children who want to participate in and touch everything. Therefore, insufficient safety is one of the most serious known drawbacks of blenders and urgently needs to be addressed. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model provides a mixer with higher safety.
[0005] This utility model is achieved through the following technical solution:
[0006] A blender includes a cup body and a base.
[0007] The base is equipped with a connecting rod, a guide rod and a sensing element, and the base includes a cup holder, which includes an outer ring portion and an inner ring portion disposed inside the outer ring portion;
[0008] One end of the cup body is an open end and the other end is a closed end, and the open end is threaded to the outer ring.
[0009] At least part of the connecting rod is housed within the outer ring.
[0010] A sealing element is also provided on the end face of the inner ring;
[0011] The guide rod includes triggered and non-triggered positions;
[0012] When the cup body is not installed on the base, the connecting rod abuts against the side wall of the seal; the guide rod is in the non-triggered position. At this time, the sensor is not activated and the blender cannot be turned on.
[0013] When the cup is installed on the base, the open end of the cup squeezes and pushes the connecting rod to move outward along the radial direction of the mixer away from the seal, thereby driving the guide rod to move from the non-triggered position to the triggered position. At this time, the sensor is activated and the mixer can be turned on and run.
[0014] Furthermore, a support plate is provided inside the inner ring to support the connecting rod.
[0015] Furthermore, the cup holder also includes a first elastic element, one end of which abuts against the connecting rod and the other end of which abuts against the inner ring.
[0016] When the cup body is removed from the cup holder, the connecting rod, under the elastic force of the first elastic element, cancels its pushing action on the guide rod. At this time, the guide rod moves from the triggered position to the non-triggered position.
[0017] Furthermore, the connecting rod includes a first protrusion, and a first through hole is provided on the side wall of the outer ring portion, with the first protrusion passing through the first through hole and located on the inner side of the outer ring portion.
[0018] Furthermore, a first inclined surface is formed on the first protrusion. When the cup body is installed on the base, the open end of the cup body abuts against the first inclined surface and pushes the connecting rod to move in the radial direction of the mixer.
[0019] Furthermore, the feature is that a support plate is provided inside the inner ring to support the connecting rod. The connecting rod includes a second protrusion. A second through hole is provided on the support plate. The second protrusion passes through the second through hole and is located below the support plate. When the cup body is not installed on the base, the second protrusion and the guide rod are misaligned.
[0020] Furthermore, a second inclined surface is formed at the bottom of the second protrusion. When the cup body is installed on the base, the second inclined surface abuts against the guide rod and drives the guide rod to move along the axial direction of the mixer. The guide rod moves from the non-trigger position to the trigger position.
[0021] Furthermore, the mixer also includes a fixed frame, which is fixedly connected to the base, and the sensing element is mounted on the fixed frame, while the guide rod is slidably mounted on the fixed frame.
[0022] Furthermore, a second elastic element is fitted onto the guide rod, with one end of the second elastic element abutting against the guide rod and the other end abutting against the fixing frame.
[0023] Furthermore, the mixer also includes a motor and a blade assembly. The motor is located inside the base, and the blade assembly is located in the cavity of the cup body. The motor is used to drive the blade assembly to rotate around the rotation axis.
[0024] Furthermore, the mixer also includes a coupling comprising a first coupling portion and a second coupling portion that mesh with each other. The first coupling portion further includes a drive shaft extending into the cavity of the cup body, the drive shaft being detachably connected to the cutter assembly. The second coupling portion is fastened to the output shaft of the motor.
[0025] Furthermore, the first coupling part is provided with several rib-shaped teeth, and the second coupling part is provided with several grooves, and the rib-shaped teeth and grooves mesh with each other to form an interlock.
[0026] Furthermore, the motor is powered by a battery and / or a DC power supply housed within the frame.
[0027] Compared with existing technologies, the advantages of this utility model are:
[0028] 1. By squeezing and pushing the connecting rod horizontally through the open end of the cup, the guide rod is driven from the non-trigger position to the trigger position, activating the sensor and enabling the machine base to start up, thus improving safety.
[0029] 2. By using the activation status of the sensor to provide feedback on the installation status of the cup and to control the start-up and operation of the machine base, the problem of the machine base still starting and driving the blade to rotate at high speed when the cup is not installed in place can be effectively prevented.
[0030] 3. During the triggering process, the connecting rod moves outside the seal without damaging the seal of the cup. The food inside the cup operates in a sealed state and there will be no leakage or seepage. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0041] like Figures 1 to 8As shown, a mixer according to an embodiment of the present invention includes a cup body 1 and a base 2. The base 2 houses a connecting rod 21, a guide rod 22, and a sensor 23. The base 2 also includes a cup holder 3, which comprises an outer ring portion 31 and an inner ring portion 32 disposed inside the outer ring portion 31. One end of the cup body 1 is an open end 10, and the other end is a closed end 11, with the open end 10 threadedly connected to the outer ring portion 31. At least a portion of the connecting rod 21 is housed within the outer ring portion 31; a sealing element 36 is also provided on the end face of the inner ring portion 32. The guide rod 22 includes a triggered position and a non-triggered position. When the cup body 1 is not installed on the base 2, the connecting rod 21 abuts against the side wall of the seal 36; the guide rod 22 is in the non-triggered position. At this time, the sensor 23 is not activated, and the mixer cannot be started. When the cup body 1 is installed on the base 2, the open end 10 of the cup body 1 squeezes and pushes the connecting rod 21 to move radially outward away from the seal 36, thereby driving the guide rod 22 to move from the non-triggered position to the triggered position. At this time, the sensor 23 is activated, and the mixer can be started. By using the open end 10 of the cup body 1 to squeeze and push the connecting rod 21 to move, thereby driving the guide rod 22 from the non-triggered position to the triggered position, the sensor 23 is activated, and the base 2 can be started, which is safer. By controlling the start-up of the base 2 by using the activated state of the sensor 23, the problem of the base 2 still starting and driving the blades to rotate at high speed when the cup body 1 is not installed in place can be effectively prevented. During the triggering process, the connecting rod 21 moves outside the seal 36 without damaging the seal 36 of the cup body 1. The food inside the cup body 1 operates in a sealed state without leakage or seepage.
[0042] In this embodiment, the open end 10 of the cup body 1 has a conventional threaded structure without any outward protrusion, so no alignment is required when installing it onto the base 2. Furthermore, the other end of the cup body 1 is a closed end 11, eliminating the need for a cup lid.
[0043] like Figure 2 and Figure 4 As shown, the base 2 also includes a base 4 detachably connected to the cup holder 3. A connecting rod 21 is disposed within the cup holder 3, and a guide rod 22 and a sensor 23 are disposed within the base 4. When the cup body 1 is threadedly connected to the cup holder 3, the cup body 1 presses against and pushes the connecting rod 21 to move horizontally, thereby driving the guide rod 22 to move. Using a threaded connection to install the cup body 1 onto the cup holder 3 facilitates disassembly and provides a more secure fit.
[0044] like Figure 8As shown, the mixer also includes a mounting bracket 25. The mounting bracket 25 is fixedly connected to the outer shell of the base 4 by screws (not shown in the figure), and the sensor 23 is mounted on the mounting bracket 25, while the guide rod 22 is slidably mounted on the mounting bracket 25. Furthermore, a second elastic element 24 is sleeved on the guide rod 22, with one end abutting against the guide rod 22 and the other end abutting against the mounting bracket 25. When the cup body 1 is removed from the cup holder 3, it is used to return the guide rod 22 from the triggered position to the non-triggered position, so that the base 2 returns to a state where it cannot be turned on, thus improving safety.
[0045] like Figures 2 to 7 As shown, a support plate 33 is provided inside the inner ring 32 to support the connecting rod 21. The connecting rod 21 is slidably mounted on the support plate 33 along the radial direction of the mixer.
[0046] The connecting rod 21 includes a first protrusion 211, and a first through hole 311 is provided on the side wall of the outer ring portion 31. The first protrusion 211 passes through the first through hole 311 and is located inside the outer ring portion 31. When the cup body 1 is not installed on the base 2, the connecting rod 21 abuts against the outer side wall of the seal 36. When the cup body 1 is installed on the base 2, the seal 36 abuts against both the opening end 10 of the cup body 1 and the upper wall of the inner ring portion 32. Since the first through hole 311, which cooperates with the first protrusion 211 of the connecting rod 21, is located on the side wall of the outer ring portion 31, and the connecting rod 21 moves horizontally outward and away from the seal 36, the seal 36 has a complete structure, and the sealing performance of the seal 36 will not be damaged. During use, this avoids the situation where liquid leakage occurs due to the damage to the seal, endangering the motor and electrical components inside the base.
[0047] A first inclined surface 214 is formed on the first protrusion 211. When the cup body 1 is installed on the base 2, the open end 10 of the cup body 1 abuts against the first inclined surface 214 and pushes the connecting rod 21 to move in the radial direction of the mixer. Specifically, a receiving cavity 312 is formed between the inner wall and the outer wall of the outer ring portion 31. When the cup body 1 is installed on the base 2, the first protrusion 211 moves in the radial direction of the mixer and enters the receiving cavity 312. By setting the first inclined surface 214, when the cup body 1 is installed on the base 2, the first inclined surface 215 abuts against the open end 10 of the cup body 1, which facilitates force application and movement in the radial direction of the mixer.
[0048] Furthermore, the connecting rod 21 includes a second protrusion 212, and a second through hole 331 is provided on the support plate 33. The second protrusion 212 passes through the second through hole 331 and is located below the support plate 33. When the cup body 1 is not installed on the base 2, the second protrusion 212 and the guide rod 22 are misaligned. A second inclined surface 215 is formed at the bottom of the second protrusion 212. When the cup body 1 is installed on the base 2, the second inclined surface 215 abuts against the guide rod 22 and drives the guide rod 22 to move along the axial direction of the mixer, and the guide rod 22 moves from the non-triggered position to the triggered position.
[0049] Furthermore, the cup holder 3 also includes a first elastic element 34, one end of which abuts against the connecting rod 21 and the other end against the inner ring 32. Specifically, the first elastic element 34 is fitted onto the third protrusion 213 of the connecting rod 21 to prevent misalignment during movement. When the cup body 1 is removed from the cup holder 3, the connecting rod 21, under the elastic force of the first elastic element 34, releases its pushing action on the guide rod 22. At this time, the guide rod 22 moves from the triggered position to the non-triggered position, thus enhancing safety.
[0050] The following is a detailed description of the transmission structure of the mixer.
[0051] The blender also includes a motor and a blade assembly 5. The motor is housed within the base 2, and the blade assembly 5 is located within the cavity of the cup body 1. The motor drives the blade assembly 5 to rotate around the rotation axis L, thereby blending and chopping the food in the cup body 1. The motor is powered by a battery and / or a DC power supply housed within the base 4. Furthermore, the direction of the rotation axis L can be vertical or approximately vertical.
[0052] The mixer also includes a coupling 41, which comprises a first coupling portion 42 and a second coupling portion 43 that mesh with each other. The first coupling portion 42 further includes a drive shaft 35 extending into the cavity of the cup body 1, and the drive shaft 35 is detachably connected to the cutter assembly 5. The second coupling portion 43 is fastened to the output shaft of the motor. The first coupling portion 42 has a plurality of protruding rib-like teeth 421, and the second coupling portion 43 has a plurality of grooves 431. The rib-like teeth 421 and the grooves 431 mesh with each other to form an interlock. In this embodiment, the specific number of rib-like teeth 421 and grooves 431 is six, but it is also preferable to use other attachment geometries and / or interlocking features, such as two, three, four, five, or more than six. The connection between the first coupling 36 and the second coupling 44 is achieved by using a mechanical interlocking method, facilitating installation and disassembly.
[0053] This invention discloses a mixer in one embodiment. By using the open end 10 of the cup body 1 to press and push the connecting rod 21, which in turn drives the guide rod 22 from a non-triggered position to a triggered position, the sensor 23 is activated, enabling the machine base 2 to start and operate, thus enhancing safety. Controlling the start-up operation of the machine base 2 by using the activated state of the sensor 23 effectively prevents the machine base 2 from starting and driving the blades to rotate at high speed even when the cup body 1 is not properly installed. The connection between the first coupling 36 and the second coupling 44 is achieved through a mechanical interlock, facilitating installation and disassembly. When the cup body 1 is removed from the cup base 3, the connecting rod 21 is reset using the first elastic element 34, removing the pushing action on the guide rod 22. The guide rod 22 is then moved from the triggered position to the non-triggered position using the second elastic element 24, restoring the machine base 2 to its inoperable state, further enhancing safety.
[0054] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
