Description

Technical Field

[0001] This utility model relates to the field of food processor technology, specifically to a safety structure with replaceable double cup lids. Background Technology

[0002] A food processor is essentially a multi-functional blender. It can not only blend fruits, vegetables, and eggs, but also mince meat, grind powder, make soy milk, and more. It is very suitable for families with diverse needs, making cooking more convenient and faster.

[0003] Existing food processors generally consist of a main body and a food processor cup. The existing food processor cups use a double-lid structure for heat insulation. However, the inner and outer lids of the existing double-lid structure can rotate relative to each other, cannot be disassembled for washing, and are not designed to be replaceable with other functional lids, which makes it inconvenient for users and affects the user experience. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a safety structure with a replaceable double cup lid.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] A safety structure with a replaceable double cup lid includes an inner lid and an outer lid. The inner lid is mounted on the outer lid. The inner lid is provided with a fixing elastic piece. The outer lid has a positioning protrusion and a positioning groove for inserting the fixing elastic piece. The inner lid rotates along the inner wall of the outer lid so that the fixing elastic piece is inserted into the positioning groove and the inner lid is forced to snap and fix on the outer lid.

[0007] Preferably, the inner cover has an installation groove, the fixed elastic piece is placed in the installation groove, the installation groove has a fixing hole for locking the fixed elastic piece, and the fixed elastic piece has a connecting hole for connecting the fixing hole. Through the above improvements, the fixing hole and the connecting hole are used to cooperate, and the fixed elastic piece is locked in the installation groove by screws and other fasteners, ensuring the reliability of the installation of the fixed elastic piece.

[0008] Preferably, the fixed elastic piece includes a connecting leg and an elastic snap-fit ​​portion. The elastic snap-fit ​​portion has a sliding inclined surface, and the positioning protrusion has a guiding inclined surface. During the snap-fit ​​process between the inner cover and the outer cover, the sliding inclined surface slides against the guiding inclined surface. Through the above improvements, the connecting leg is used to connect with the inner cover, so that the fixed elastic piece is fixed on the inner cover. During the snap-fit ​​process between the inner cover and the outer cover, the inner cover can be rotated to make the sliding inclined surface on the elastic snap-fit ​​protrusion slide along the guiding inclined surface until the fixed elastic piece slides into the positioning groove, realizing the quick snap-fit ​​between the inner cover and the outer cover. Furthermore, due to the elasticity of the fixed elastic piece, the inner cover will not detach from the outer cover during the normal rotation of the entire cup lid.

[0009] Preferably, a hanging piece is formed on the inner cover, and a fixing baffle is formed on the outer cover. The fixing baffles form a first limiting groove for the hanging piece to be inserted. With the above improvement, when the inner cover and the outer cover are connected, the hanging piece will slide into the first limiting groove between the fixing baffles. The first limiting groove will limit and fix the hanging piece, ensuring the reliability of the connection between the inner cover and the outer cover, and providing guidance for the inner cover during rotation.

[0010] Preferably, the inner cover is further provided with a limiting baffle, and the limiting baffle and the hanging piece form a second limiting groove for the fixing baffle to be inserted. Through the above improvements, the first limiting groove and the second limiting groove cooperate to make the fixing baffle, the hanging piece and the limiting baffle interlock and limit each other, further improving the stability of the connection between the inner cover and the outer cover.

[0011] Preferably, the hanging piece is placed in the first limiting groove so that a heat insulation gap is formed between the inner cover and the outer cover. Through the above improvements, the heat insulation effect is enhanced, and users are prevented from being burned.

[0012] Preferably, the inner cover has a clearance groove for inserting a fixing baffle. With the above improvement, during the installation process, the fixing baffle is first aligned with the clearance groove, and then the inner cover is placed on the outer cover and rotated to engage the inner cover and the outer cover.

[0013] Preferably, a sealing groove is formed on the inner cover, a sealing ring is provided in the sealing groove, and a fixing bracket for fixing the sealing ring is provided on the inner cover. The fixing bracket abuts against the sealing ring. Through the above improvements, the sealing performance between the inner cover and the cooking cup is increased.

[0014] Preferably, the inner cover has an activation protrusion for driving the inner cover to rotate. With the above improvements, the inner cover can be rotated using the activation protrusion, which improves the convenience of disassembling and installing the inner cover.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0016] By setting a fixed elastic piece on the inner cover and a positioning protrusion on the outer cover, and a positioning groove on the positioning protrusion, the inner cover can be rotated to allow the fixed elastic piece on the inner cover to be placed into the positioning groove, thereby achieving a quick connection between the inner cover and the outer cover. This makes it easier to install and remove the inner cover, and also makes it easier for users to replace the inner cover with other functional inner covers, improving the convenience of use and greatly enhancing the user experience.

[0029] like Figure 1-9 As shown, a safety structure with a replaceable double cup lid includes an inner lid 1 and an outer lid 2. The inner lid 1 is mounted on the outer lid 2. A fixing elastic piece 3 is provided on the inner lid 1. A positioning protrusion 4 is formed on the outer lid 2, and a positioning groove 5 is formed on the positioning protrusion 4 for inserting the fixing elastic piece 3. The inner lid 1 rotates along the inner wall of the outer lid 2 so that the fixing elastic piece 3 is inserted into the positioning groove 5, and the inner lid 1 is forced to snap and fix on the outer lid 2.

[0030] By rotating the inner cover 1, the fixing elastic piece 3 on the inner cover 1 is placed into the positioning groove 5, so as to realize the quick connection between the inner cover 1 and the outer cover 2, making it easier to install and remove the inner cover 1, making it easier for users to replace the inner cover 1 with other functions, and allowing the outer cover 2 to be matched with different types of outer covers 2, improving the convenience of users in the process of use and greatly enhancing the user experience.

[0031] like Figures 1 to 8 As shown, a further explanation of the installation of the fixed elastic piece 3 in this embodiment is provided: an installation groove 1.1 is formed on the inner cover 1, the fixed elastic piece 3 is placed in the installation groove 1.1, the installation groove 1.1 is provided with a fixing hole 1.2 for locking the fixed elastic piece 3, and a connecting hole 1.3 is formed on the fixed elastic piece 3 to connect the fixing hole 1.2. The fixing hole 1.2 and the connecting hole 1.3 are used to cooperate, and the fixed elastic piece 3 is locked in the installation groove 1.1 by screws and other fasteners, which ensures the reliability of the installation of the fixed elastic piece 3.

[0032] like Figures 1 to 8 As shown, as a further explanation of the cooperation between the fixed elastic piece 3 and the outer cover 2, the fixed elastic piece 3 includes a connecting leg 1.4 and an elastic snap-fit ​​part 1.5. A sliding slope 1.6 is formed on the elastic snap-fit ​​part 1.5, and a guide slope 1.7 is formed on the positioning protrusion 4.

[0033] During the engagement of the inner cover 1 and the outer cover 2, the inner cover 1 can be rotated to allow the sliding inclined surface 1.6 on the elastic engagement protrusion to slide along the guide inclined surface 1.7 until the fixed elastic piece 3 slides into the positioning groove 5, thereby achieving quick engagement of the inner cover 1 and the outer cover 2. Furthermore, due to the elasticity of the fixed elastic piece 3, the inner cover 1 will not detach from the outer cover 2 during normal rotation of the entire cup lid.

[0034] like Figures 1 to 7 As shown, a further explanation of the cooperation between the inner cover 1 and the outer cover 2 is provided: a hanging piece 2.1 is formed on the inner cover 1, and a fixing baffle 2.2 is formed on the outer cover 2. The fixing baffles 2.2 form a first limiting groove 2.3 in which the hanging piece 2.1 is inserted. During the connection process between the inner cover 1 and the outer cover 2, the hanging piece 2.1 can rotate along the first limiting groove 2.3 and provide guidance for the inner cover 1 during rotation, thus ensuring the stability of the rotation of the inner cover 1.

[0035] In addition, during the connection process of the inner cover 1 and the outer cover 2, the first limiting groove 2.3 will limit and fix the hanging piece 2.1, ensuring the reliability of the connection between the inner cover 1 and the outer cover 2.

[0036] Preferably, the inner cover 1 is also provided with a limiting baffle 2.4. The limiting baffle 2.4 and the hanging piece 2.1 form a second limiting groove 2.5 for the fixing baffle 2.2 to be inserted, so that the fixing baffle 2.2, the hanging piece 2.1 and the limiting baffle 2.4 are mutually interlocked and limited, which further improves the stability of the connection between the inner cover 1 and the outer cover 2, and further improves the stability of the inner cover 1 during rotation.

[0037] Preferably, the hanging piece 2.1 is placed in the first limiting groove 2.3 so that a heat insulation gap 2.6 is formed between the inner cover 1 and the outer cover 2, which greatly improves the heat insulation effect, avoids scalding the user, and ensures safety.

[0038] Preferably, the inner cover 1 has a clearance groove 2.7 for inserting the fixing baffle 2.2. During the installation process, the fixing baffle 2.2 and the clearance groove 2.7 are aligned first, and then the inner cover 1 is placed on the outer cover 2 and the inner cover 1 is rotated to lock the inner cover 1 and the outer cover 2 together.

[0039] like Figure 1 As shown, preferably, the inner cover 1 has an activation protrusion 3.4 for driving the inner cover 1 to rotate. The activation protrusion 3.4 can be used to rotate the inner cover 1, improving the convenience of disassembling and installing the inner cover 1.

[0040] like Figure 2As shown, as a further explanation of the sealing of the inner cover 1, a sealing groove 3.1 is formed on the inner cover 1, a sealing ring 3.2 is provided in the sealing groove 3.1, and a fixing bracket 3.3 for fixing the sealing ring 3.2 is provided on the inner cover 1. The fixing bracket 3.3 abuts against the sealing ring 3.2, which increases the sealing between the inner cover 1 and the cooking cup.

[0041] like Figure 3 As shown, in some other embodiments, the outer cover 2 is provided with a safety pressure plate 3.5 and a safety groove 3.6. When the outer cover 2 is used alone, the outer cover 2 cannot be screwed into the handle of the cooking cup independently, and cannot be used alone. It will not trigger the safety interlock. It must be used in conjunction with a safety structure similar to the inner cover 1. Similarly, the inner cover 1 cannot be used alone and cannot trigger the safety switch. Therefore, this cup lid combination can replace the inner cover 1 with other functions while keeping the outer cover 2 unchanged, realizing a multi-functional lid and improving practicality and convenience.

[0042] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
