Description

Technical Field

[0001] This utility model relates to the field of food processing machine technology, and more specifically to a cup assembly anti-retraction device for a mixer. Background Technology

[0002] A blender is a common food processor, and its accompanying cup assembly consists of a cup and a cup holder, which are mainly fixed together by threads or other unidirectional rotating engagement mechanisms. However, this connection method only provides fixation in one direction; there is no structural constraint preventing the cup from detaching from the cup holder in the opposite direction. In this situation, if the user uses the product excessively or if the product malfunctions, the cup and cup holder may detach, potentially leading to a safety hazard.

[0003] To address the above issues, Chinese utility model patent CN 211609439U discloses a stirrer cup anti-reverse device, comprising: a main unit and a cup assembly detachably mounted on the upper end of the main unit; the cup assembly includes: a cup seat and a stirrer cup screwed to the upper end of the cup seat, the bottom of the stirrer cup is provided with an annular anti-reverse groove, the cup seat includes a cup seat bracket, an anti-reverse rod for cooperating with the anti-reverse groove is slidably mounted on the inner side of the cup seat, the bottom of the anti-reverse rod is provided with an elastic element, and the bottom of the elastic element abuts against the cup seat bracket.

[0004] While the above patents can prevent the mixing cup from spinning out of its holder and thus provide protection, this method of using a stop rod and a stop tooth groove is prone to problems. Due to the tapered angle of the stop tooth groove and the significant vibration of the main unit, the stop rod can easily dislodge from the stop tooth groove, resulting in poor anti-reverse performance. Furthermore, the addition of annular stop teeth grooves at the bottom of the mixing cup necessitates a redesign and mold creation for the cup, increasing the production cost of the mixer. Therefore, we provide a cup assembly anti-reverse device for a mixer. Utility Model Content

[0005] This utility model provides a cup assembly anti-retraction device for a mixer, aiming to solve the problems of existing mixer cup anti-retraction devices that use an anti-retraction rod and anti-retraction groove to engage, which makes it easy for the anti-retraction rod to fall out of the anti-retraction groove, resulting in poor anti-retraction effect of the device.

[0006] The present invention adopts the following technical solution:

[0007] A cup assembly anti-retraction device for a mixer includes a cup assembly, an anti-retraction rod, and an elastic element. The cup assembly includes a mixing cup and a cup base. The lower part of the mixing cup is fixedly connected to the cup base by a thread or by a directional rotational snap-fit. An anti-retraction limiting part is formed on the mixing cup. The anti-retraction rod is installed on the cup base through the elastic element. When the cup assembly abuts against the main body of the mixer, the anti-retraction rod is pushed up under the action of external force, and its side abuts against the side of the anti-retraction limiting part to prevent the mixing cup from separating from the cup base. When the cup assembly leaves the main body of the mixer, the anti-retraction rod leaves the side of the anti-retraction limiting part under the action of the elastic element, and the mixing cup and the cup base can be separated normally.

[0008] In a preferred embodiment, a plurality of anti-retraction limiting parts are formed on the stirring cup, and a plurality of anti-retraction rods are provided accordingly.

[0009] In a preferred embodiment, the stirring cup and the cup base are fixedly connected by a snap-fit ​​method. A plurality of snap-fit ​​blocks are provided at intervals on the lower inner sidewall of the stirring cup, and a plurality of snap-fit ​​grooves are provided on the cup base accordingly. Each snap-fit ​​groove has a snap-fit ​​interface, and the snap-fit ​​block protrudes outside the snap-fit ​​interface, and the protruding part forms the anti-retraction limiting part.

[0010] In a preferred embodiment, the stirring cup and the cup base are fixed by a threaded connection, and the side wall of the stirring cup is provided with a rib, which forms the anti-retraction limiting part.

[0011] In a preferred embodiment, the anti-reverse lever includes an upper limit lever, a lower limit lever, and a limiting boss, with the limiting boss connecting the upper limit lever and the lower limit lever.

[0012] In a preferred embodiment, the cup holder is provided with an installation chamber, the upper end face and the lower end face of the installation chamber are respectively provided with an upper through hole and a lower through hole, the upper limit rod is correspondingly provided in the upper through hole, the lower limit rod is inserted in the lower through hole, the limiting boss is installed in the installation chamber, and the elastic element is installed on the upper limit rod between the upper through hole and the limiting boss.

[0013] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following advantages:

[0014] 1. This utility model features an anti-retraction limiting part on the mixing cup. The anti-retraction rod abuts against the side of the anti-retraction limiting part to limit the movement between the mixing cup and the cup base. This anti-retraction method is stable and will not cause the anti-retraction rod to come off, thus improving the anti-retraction effect of the cup assembly anti-retraction device and ensuring the safety of the mixer in use.

[0015] 2. The mixing cup and cup base of this utility model are fixedly connected by a snap-fit ​​block and a snap-fit ​​groove. A portion of the snap-fit ​​block protrudes from the side of the snap-fit ​​groove, directly forming an anti-retraction limiting part that cooperates with the anti-retraction rod. This structure eliminates the need for an additional anti-retraction limiting part and avoids the need for redesigning the mold, thus saving on equipment production costs.

[0023] The following reference Figure 1 The specific embodiments of this utility model are described below. To provide a comprehensive understanding of this utility model, many details are described below; however, those skilled in the art can implement this utility model without these details. Well-known components, methods, and processes will not be described in detail below.

[0024] Example 1

[0025] A cup assembly anti-retraction device for a blender, as described in the following figure. Figure 1 and Figure 2 Installed on the main body 1 of the mixer, it includes a cup assembly, an anti-reverse rod 21, and an elastic element 31. The cup assembly includes a mixing cup 11 and a cup base 12. A blade assembly is installed inside the mixing cup 11. The blade assembly is a common crushing blade in the art and is not the focus of this embodiment, so it will not be described in detail here.

[0026] Reference Figure 2In this embodiment, the stirring cup 11 and the cup holder 12 are fixedly connected by a snap-fit ​​mechanism. Specifically, the lower inner sidewall of the stirring cup 11 is provided with a plurality of snap-fit ​​blocks 111 at intervals, and the cup holder 12 is provided with a plurality of snap-fit ​​grooves 121 correspondingly. Each snap-fit ​​groove 121 has a snap-fit ​​interface, and the snap-fit ​​block 111 enters the snap-fit ​​groove 121 through the snap-fit ​​interface to fix the stirring cup 11 on the cup holder 12. A portion of the snap-fit ​​block 111 protrudes outside the snap-fit ​​interface, and this protruding portion forms an anti-retraction limiting part.

[0027] Reference Figure 2 and Figure 3 The aforementioned anti-retraction rod 21 is mounted on the cup holder 12 via an elastic element. Specifically, the cup holder 12 is provided with an installation chamber 130, and the upper and lower end faces of the installation chamber 130 are respectively provided with an upper through hole 131 and a lower through hole 132. The anti-retraction rod includes an upper limit rod 211, a lower limit rod 212, and a limiting boss 213. The limiting boss 213 connects the upper limit rod 211 and the lower limit rod 212. The upper limit rod 211 is correspondingly located in the upper through hole, the lower limit rod is inserted into the lower through hole, and the limiting boss 213 is installed in the installation chamber 130. The elastic element 31 is preferably a spring, which is installed on the upper limit rod 211 between the upper through hole 131 and the limiting boss 213.

[0028] Reference Figure 3 When an external force presses the cup assembly against the mixer main unit 1, the anti-retraction rod 21 compresses the spring upward under the action of the external force, causing the upper limit rod 21 to protrude from the upper end face of the cup holder 12 and abut against the side of the protruding part of the aforementioned locking block 111. Under the restriction of the anti-retraction rod, the locking block 111 cannot be dislodged from the locking groove 121, ensuring that the mixing cup 11 will not dislodge from the cup holder 12 during operation.

[0029] Reference Figure 4 When the cup assembly leaves the main unit 1 of the mixer, the anti-retraction rod 21, under the elastic force of the spring, pushes the lower limit rod 212 down and into the lower through hole 132. The upper limit rod 211 also moves down and leaves the side of the anti-retraction limit part. At this time, rotating the mixing cup 11 will cause the locking block 111 to exit the locking groove 121, thereby separating the mixing cup 11 from the cup holder 12.

[0030] Example 2

[0031] The main difference between this embodiment and Embodiment 1 is that: (Refer to...) Figures 5 to 7 The mixing cup 11 and the cup holder 12 are fixedly connected by a thread in this embodiment. Furthermore, the inner wall of the mixing cup 11 in this embodiment is provided with a raised rib 112, which forms an anti-retraction limiting part. An anti-retraction rod 21 protruding from the cup holder 12 is located on the side of the raised rib 112 and is used to limit the movement of the raised rib 112 in the opposite direction to the rotational fastening of the mixing cup 11 and the cup holder 12.

[0032] Reference Figure 7 When the cup assembly leaves the mixer main unit 1, meaning the cup assembly loses external force, the anti-reverse lever 21, under the elastic force of the spring, pushes the lower limit lever 212 downwards and inserts it into the lower through hole 132. Simultaneously, the upper limit lever 211 also moves downwards, leaving the side of the rib 112 and positioned below it. Rotating the mixing cup 11 separates the mixing cup 11 from the cup base 12.

[0033] Compared to Example 1, this embodiment requires additional ribs on the mixing cup, resulting in a relatively higher production cost.

[0034] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
