Description

Technical Field

[0001] The present invention relates to the technical field of cooking machines, and particularly relates to a cooking machine with dual safety functions. Background Art

[0002] With the increasing improvement of people's living standards, many different types of food processors have emerged on the market. Among them, a cooking machine integrates functions such as making soy milk, grinding dry powder, squeezing juice, making minced meat, and shaving ice, and is a household appliance used to make various foods such as juice, soy milk, jam, dry powder, shaved ice, and minced meat. It is a product after the juicer has become more diversified.

[0003] In order to facilitate the cleaning of the cutter, the cutter of the existing cooking machine is set to be detachable. For example, a cooking machine assembly disclosed in the publication number "CN117617789A" includes a lower-driven cooking machine and a cutter removal device. The inner wall of the cup body of the cooking machine is provided with convex ribs along the axial direction. The cutter removal device includes a cutter removal rod and a cutter removal seat. The inner wall of the cutter removal seat is provided with a limiting member for restricting the cutter of the lower-driven cooking machine from rotating circumferentially along with the output shaft of the motor. The cutter removal rod passes through a through hole provided at the center of the cutter removal seat and matching the diameter of the cutter removal rod. The outer wall of the cutter removal seat is provided with a clamping member with a protrusion that forms a toothed engagement with the convex ribs.

[0004] During the process of removing the cutter of a similar cooking machine, if the switch is accidentally pressed, the driving motor will still be started, which is likely to cause an accident and harm the user, greatly reducing the safety of the cooking machine. Summary of the Invention

[0005] In order to solve the technical problems in the background art, the present invention proposes a cooking machine with dual safety functions.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows:

[0007] A cooking machine with dual safety functions includes a main body, a mixing cup arranged on the main body, and a cup cover assembly covered on the mixing cup. Connecting handles for clamping and fixing the cup cover assembly are formed on both sides of the mixing cup, and a plugging groove for inserting the outer contour of the cup cover assembly is provided on the connecting handle;

[0008] The cup cover assembly includes an inner cover and an outer cover. The inner cover is rotatably clamped to the outer cover, and the inner cover and the outer cover are rotatably sleeved with each other. A fixing elastic sheet is provided between the inner cover and the outer cover. The fixing elastic sheet is fixed on the inner cover and is positioned and abutted against the outer cover to force the inner cover to be clamped and fixed to the outer cover;

[0009] A microswitch for controlling the start of the mixing cup is provided inside the main body. A starting slide rod is slidably arranged inside the connecting handle. An extrusion convex part for driving the starting slide rod to slide is formed on the outer cover. A screwing groove communicating with the insertion slot is formed on one side of the connecting handle. The extrusion convex part rotates along the screwing groove and abuts against the starting slide rod to force the starting slide rod to slide downward to extrude the microswitch.

[0010] A blocking piece for restricting the entry of the extrusion convex part is provided at the screwing end of the screwing groove, and the blocking piece is partially placed inside the insertion slot. The blocking piece always has a tendency to protrude into the screwing groove. A pressing convex part is provided on the outer contour of the inner cover, and an exposure groove for exposing the pressing convex part is provided on the outer contour of the outer cover.

[0011] The exposure groove is located in front of the extrusion convex part with respect to the assembly path. When the cup cover assembly is inserted into the insertion slot, the exposure groove is arranged opposite to the blocking piece. The pressing convex part presses the blocking piece away from the assembly path so that the extrusion convex part is inserted into the screwing groove and brakes the starting slide rod.

[0012] Preferably, a rotating seat is provided on the connecting handle. The blocking piece is rotatably arranged on the rotating seat, and an elastic element is sleeved on the rotating seat. One end of the elastic element abuts against the rotating seat, and the other end abuts against the blocking piece so that the blocking piece always has a tendency to move towards the screwing groove. Through the above improvement, the elastic element acts on the blocking piece, so that the blocking piece always has a tendency to rotate towards the screwing groove. Thus, when the cup cover assembly is separated from the insertion slot, the blocking piece will be reinserted into the screwing groove to avoid accidentally touching the starting slide rod and ensure safety.

[0013] Preferably, a first extrusion inclined surface is provided on the extrusion convex part, and a second extrusion inclined surface matching with the first extrusion inclined surface is provided on the starting slide rod. Through the above improvement, as the inner cover and the outer cover rotate, the extrusion convex part on the outer cover will rotate in the screwing groove, and the first extrusion inclined surface on the extrusion convex part will slide along the second extrusion inclined surface to gradually lower the starting slide rod and extrude the microswitch. When the cup cover assembly is disassembled, the extrusion convex part moves away from the starting slide rod, and the starting slide rod is reset under the action of the starting end of the microswitch.

[0014] Preferably, a positioning convex part is formed on the starting slide rod, and a positioning groove for the positioning convex part to be inserted is formed on the extrusion convex part. Through the above improvement, after the extrusion convex part rotates to a specified position, the positioning convex part will be inserted into the positioning groove, thus ensuring the stability of the connection between the starting slide rod and the outer cover, and avoiding the position deviation between the extrusion convex part and the starting slide rod during the stirring process of the mixing cup, which may cause the interruption of stirring and affect the user experience.

[0015] Preferably, a guiding convex portion is formed on the connecting handle, and a guiding groove for the guiding convex portion to be inserted into is formed on the starting sliding rod. Through the above improvement, the stability of the starting sliding rod during the up-and-down sliding process is improved.

[0016] Preferably, the exposed groove is adjacent to the extrusion convex portion, and during the rotation of the outer cover, the exposed groove first enters the insertion groove. Through the above improvement, during the rotation, the exposed groove first enters the insertion groove. If the inner cover is not installed on the outer cover, the blocking piece cannot be pressed down to ensure that the cup cover assembly is connected to the mixing cup when the assembly is completed.

[0017] Preferably, the fixed elastic piece includes a connecting support leg and an elastic clamping portion. A sliding inclined surface is formed on the elastic clamping portion. A fixed convex portion is formed on the outer cover. A fixing groove for the fixed elastic piece to be inserted into is formed on the fixed convex portion. And a guiding inclined surface is formed on the fixed convex portion. During the clamping process of the inner cover and the outer cover, the sliding inclined surface slides along the guiding inclined surface. Through the above improvement, the connecting support leg is used to connect with the inner cover to fix the fixed elastic piece on the inner cover. When clamping the inner cover and the outer cover, the inner cover can be rotated to make the sliding inclined surface on the elastic fixing convex portion slide along the guiding inclined surface until the fixed elastic piece slides into the positioning groove, realizing the quick clamping of the inner cover and the outer cover. And due to the elasticity of the fixed elastic piece, the inner cover will not separate from the outer cover during the normal rotation of the whole cup cover.

[0018] Preferably, a hanging piece is formed on the inner cover, and a fixed blocking piece is formed on the outer cover. A first limiting groove for the hanging piece to be inserted into is formed between the fixed blocking pieces. A limiting blocking piece is also arranged on the inner cover. A second limiting groove for the fixed blocking piece to be inserted into is formed between the limiting blocking piece and the hanging piece. Through the above improvement, during the connection process of the inner cover and the outer cover, the hanging piece will slide into the first limiting groove between the fixed blocking pieces, and 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.

[0019] Preferably, a sealing groove is formed on the inner cover. A sealing ring is arranged in the sealing groove. And a fixing frame for fixing the sealing ring is clamped on the inner cover. The fixing frame abuts against the sealing ring. Through the above improvement, the sealing performance between the inner cover and the cooking cup is increased.

[0020] Preferably, the hanging piece is inserted into the first limiting groove so that a heat insulation gap is formed between the inner cover and the outer cover. Through the above improvement, the heat insulation effect is improved to avoid scalding the user.

[0021] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0022] By providing an extrusion protrusion on the outer cover and slidably arranging a starting slide rod inside the connecting handle, a screwing groove communicating with the insertion slot is formed on one side of the connecting handle. When the extrusion protrusion rotates along the screwing groove and abuts against the starting slide rod to force the starting slide rod to slide down and squeeze the microswitch, the stirring cup can be started to work at this time. This ensures that the stirring cup can only be started when the cup cover assembly rotates into place. Moreover, a blocking piece that restricts the entry of the extrusion protrusion is provided at the screwing end of the screwing groove. Only when the inner cover and the outer cover are assembled together and inserted into the insertion slot at the same time, the blocking piece will be retracted into the connecting handle, thus preventing the external structure from accidentally touching the starting slide rod and further improving the safety of the food processor.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] It should be understood that although the terms upper, middle, lower, top, one end, etc. appear in this text to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for easy understanding, rather than to define any limitation in direction or order.

[0037] As Figures 1-11 shown, a cooking machine with double safety functions includes a main body 1, a stirring cup 2 arranged on the main body, and a cup cover assembly 3 covering the stirring cup 2. Connecting handles 4 for clamping and fixing the pot cover assembly are formed on both sides of the stirring cup 2, and an insertion slot 1.1 for placing the outer contour of the cup cover assembly 3 is formed on the connecting handle 4.

[0038] Specifically, the cup cover assembly 3 includes an inner cover 1.2 and an outer cover 1.3. The inner cover 1.2 is rotatably and detachably connected to the outer cover 1.3, and the inner cover 1.2 and the outer cover 1.3 are rotatably sleeved with each other. A fixed elastic piece 4.1 is arranged between the inner cover 1.2 and the outer cover. The fixed elastic piece 4.1 is fixed on the inner cover 1.2 and is positioned and abutted against the outer cover 1.3 to force the inner cover 1.2 to be clamped and fixed on the outer cover 1.3.

[0039] Moreover, a microswitch 1.4 for controlling the start of the mixing cup 2 is provided inside the main body 1. A starting slide bar 1.5 is slidably arranged inside the connecting handle 4. An extrusion convex part 1.6 for driving the starting slide bar 1.5 to slide is formed on the outer cover 1.3. A screwing groove 1.7 communicating with the insertion slot 1.1 is formed on one side of the connecting handle 4. The extrusion convex part 1.6 rotates along the screwing groove 1.7 and abuts against the starting slide bar 1.5 to force the starting slide bar 1.5 to slide downward to extrude the microswitch 1.4. The mixing cup 2 can only work when the starting slide bar 1.5 extrudes the starting end of the microswitch 1.4, so as to ensure safety.

[0040] Furthermore, a blocking piece 1.8 for restricting the entry of the extrusion convex part 1.6 is provided at the screwing end of the screwing groove 1.7, and the blocking piece 1.8 is partially placed inside the insertion slot 1.1. The blocking piece 1.8 always has a tendency to protrude into the screwing groove 1.7. A pressing convex part 1.9 is provided on the outer contour of the inner cover 1.2, and an exposing groove 2.7 for exposing the pressing convex part 1.9 is provided on the outer contour of the outer cover 1.3. When the cup cover assembly 3 is placed inside the insertion slot 1.1, since the blocking piece 1.8 extends into the insertion slot 1.1, when the pressing convex part 1.9 presses the blocking piece 1.8 downward, the blocking piece 1.8 is received inside the connecting handle 4.

[0041] Since the exposing groove 2.7 is located in front of the extrusion convex part 1.6 with respect to the assembly path, when the cup cover assembly 3 is placed into the insertion slot 1.1, the exposing groove 2.7 is arranged opposite to the blocking piece 1.8, and the pressing convex part 1.9 presses the blocking piece 1.8 away from the assembly path so that the extrusion convex part 1.6 is placed into the screwing groove 1.7 and brakes the starting slide bar 1.5.

[0042] Furthermore, during the rotation of the outer cover 1.3, since the exposing groove 2.7 is adjacent to the extrusion convex part 1.6, the exposing groove 2.7 first enters the insertion slot 1.1. If the inner cover 1.2 is not installed on the outer cover 1.3, the blocking piece 1.8 cannot be pressed downward. The blocking piece 1.8 will extend into the screwing groove 1.7 and will be buckled into the exposing groove 2.7 when opposite to the exposing groove 2.7 in the assembly path, thus preventing the outer cover 1.3 from continuing to rotate along the assembly path, so as to ensure that the cup cover assembly 3 is connected to the mixing cup 2 after being assembled, thereby avoiding installing the outer cover 1.3 on the mixing cup 2 when the inner cover 1.2 is not installed, and further improving safety.

[0043] In the present invention, through the cooperation of the starting slide bar 1.5 and the extrusion convex part 1.6, and the cooperation of the blocking piece 1.8 and the pressing convex part 1.9, the cooking machine has a dual safety function, greatly improving the safety of the cooking machine.

[0044] Such as Figures 1 to 7As shown in the figure, for further explanation of the implementation of the blocking piece 1.8, a rotating seat 2.1 is provided on the connecting handle 4. The blocking piece 1.8 is rotatably arranged on the rotating seat 2.1, and an elastic element 2.2 is sleeved on the rotating seat 2.1. One end of the elastic element 2.2 abuts against the rotating seat 2.1, and the other end abuts against the blocking piece 1.8, so that the blocking piece 1.8 always has a tendency to move towards the screwing groove 1.7, and a part of the blocking piece 1.8 is placed in the inserting groove 1.1.

[0045] The elastic element 2.2 acts on the blocking piece 1.8, so that the blocking piece 1.8 always has a tendency to rotate into the screwing groove 1.7. Thus, when the cup cover assembly 3 is separated from the inserting groove 1.1, the blocking piece 1.8 will be re-placed into the screwing groove 1.7 to avoid accidentally touching and starting the sliding rod 1.5, ensuring safety.

[0046] As Figures 3 to 10 shown in the figure, for further explanation of the cooperation between the extrusion convex part 1.6 and the starting sliding rod 1.5, a first extrusion inclined surface 2.3 is formed on the extrusion convex part 1.6, and a second extrusion inclined surface 2.4 that cooperates with the first extrusion inclined surface 2.3 is formed on the starting sliding rod 1.5. During the installation process of the cup cover assembly 3, as the inner cover 1.2 and the outer cover 1.3 rotate, the extrusion convex part 1.6 on the outer cover 1.3 will rotate in the screwing groove 1.7, and the first extrusion inclined surface 2.3 on the extrusion convex part 1.6 will slide along the second extrusion inclined surface 2.4, causing the starting sliding rod 1.5 to slide down gradually and squeeze the micro switch 1.4. And only when the starting sliding rod 1.5 squeezes the starting end of the micro switch 1.4 can the stirring cup be started to ensure the safety of the cooking machine.

[0047] Furthermore, when the cup cover assembly 3 is disassembled, the extrusion convex part 1.6 moves away from the starting sliding rod 1.5, and the starting sliding rod 1.5 is reset under the action of the starting end of the micro switch 1.4, realizing the automatic reset of the starting sliding rod 1.5.

[0048] In addition, a positioning convex part 2.5 is formed on the starting sliding rod 1.5, and a positioning groove 2.6 for the positioning convex part 2.5 to be placed in is formed on the extrusion convex part 1.6. When the extrusion convex part 1.6 rotates to a specified position, the positioning convex part 2.5 will be placed in the positioning groove 2.6, thus ensuring the stability of the connection between the starting sliding rod 1.5 and the outer cover 1.3, and avoiding the position deviation between the extrusion convex part 1.6 and the starting sliding rod 1.5 during the stirring process of the stirring cup 2, resulting in the interruption of stirring and affecting the user experience.

[0049] As Figure 2 、 Figure 3As shown, for a further explanation of the cooperation between the starting slide bar 1.5 and the connecting handle 4, a guiding convex part 3.1 is formed on the connecting handle 4, and a guiding groove 3.2 for the guiding convex part 3.1 to be inserted into is formed on the starting slide bar 1.5. By using the cooperation between the guiding convex part 3.1 and the guiding groove 3.2, the stability of the starting slide bar 1.5 during the up and down process is improved.

[0050] In addition, the guiding convex part 3.1 has a clamping convex part 3.6 extending out of the connecting handle 4, and the main body 1 is formed with a clamping groove 3.7 for the clamping convex part 3.6 to be inserted into. The cooperation between the clamping convex part 3.6 and the clamping groove 3.7 can be used to realize the quick connection of the mixing cup 2 and the main body 1, and the clamping convex part 3.6 is formed on the guiding convex part 3.1, making the structure simpler and improving the convenience of assembly.

[0051] Furthermore, a limiting convex part 3.3 is formed on the connecting handle 4, and the starting slide bar 1.5 abuts against the limiting convex part 3.3. The limiting convex part 3.3 is used to limit the starting slide bar 1.5 to avoid excessive extrusion of the micro switch 1.4 and damage to the micro switch 1.4.

[0052] Preferably, an extrusion column 3.4 for extruding the micro switch 1.4 is formed at the bottom of the starting slide bar 1.5, and a guiding hole 3.5 for the extrusion column 3.4 to be inserted into is formed on the main body 1. The guiding column is arranged opposite to the starting end of the micro switch 1.4. By using the cooperation between the extrusion column 3.4 and the guiding hole 3.5, the stability of the starting slide bar 1.5 during the sliding process is further improved.

[0053] As Figures 8 to 11 shown, for a further explanation of the cooperation between the inner cover 1.2 and the outer cover 1.3 in this embodiment, a fixed elastic piece 4.1 is arranged on the inner cover 1.2, a fixed convex part 4.2 is formed on the outer cover 1.3, and a fixed groove 4.3 for the fixed elastic piece 4.1 to be inserted into is formed on the fixed convex part 4.2. The inner cover 1.2 rotates along the inner wall of the outer cover 1.3 so that the fixed elastic piece 4.1 is inserted into the fixed groove 4.3, and the inner cover 1.2 is forced to be clamped and fixed on the outer cover 1.3. By using the cooperation between the fixed groove 4.3 and the fixed elastic piece 4.1, the quick engagement of the inner cover 1.2 and the outer cover 1.3 is realized.

[0054] Specifically, the fixed elastic piece 4.1 includes a connecting leg 5.1 and an elastic clamping portion 5.2. A sliding inclined surface 5.3 is formed on the elastic clamping portion 5.2, and a guiding inclined surface 5.4 is formed on the positioning convex portion 2.5. During the clamping process of the inner cover 1.2 and the outer cover 1.3, the sliding inclined surface 5.3 slides along the guiding inclined surface 5.4. The connecting leg 5.1 is used to connect with the inner cover 1.2, so that the fixed elastic piece 4.1 is fixed on the inner cover 1.2. When clamping the inner cover 1.2 and the outer cover 1.3, the inner cover 1.2 can be rotated to make the sliding inclined surface 5.3 on the elastic fixing convex portion 4.2 slide along the guiding inclined surface 5.4 until the fixed elastic piece 4.1 slides into the positioning groove 2.6, realizing the quick clamping of the inner cover 1.2 and the outer cover 1.3. And due to the elasticity of the fixed elastic piece 4.1, during the normal rotation of the whole cup cover, the inner cover 1.2 will not separate from the outer cover 1.3.

[0055] Furthermore, a hanging piece 6.1 is formed on the inner cover 1.2, and a fixed stop piece 6.2 is formed on the outer cover 1.3. A first limiting groove 6.3 for the hanging piece 6.1 to be placed in is formed between the fixed stop pieces 6.2. During the connection process of the inner cover 1.2 and the outer cover 1.3, the hanging piece 6.1 can rotate along the first limiting groove 6.3 and provide guidance for the inner cover 1.2 during rotation, ensuring the stability of the rotation of the inner cover 1.2.

[0056] In addition, during the connection process of the inner cover 1.2 and the outer cover 1.3, the first limiting groove 6.3 will limit and fix the hanging piece 6.1, ensuring the reliability of the connection between the inner cover 1.2 and the outer cover 1.3.

[0057] Preferably, a limiting stop piece 6.4 is further provided on the inner cover 1.2. A second limiting groove 6.5 for the fixed stop piece 6.2 to be placed in is formed between the limiting stop piece 6.4 and the hanging piece 6.1, enabling the fixed stop piece 6.2, the hanging piece 6.1, and the limiting stop piece 6.4 to be mutually staggered and limited, further enhancing the stability of the connection between the inner cover 1.2 and the outer cover 1.3 and further enhancing the stability of the inner cover 1.2 during rotation.

[0058] Preferably, the hanging piece 6.1 is placed in the first limiting groove 6.3, so as to form a heat insulation gap 7.4 between the inner cover 1.2 and the outer cover 1.3, greatly improving the heat insulation effect, avoiding scalding users, and ensuring safety.

[0059] As Figure 8 shown, as a further explanation of the sealing of the inner cover 1.2, a sealing groove 7.1 is formed on the inner cover 1.2. A sealing ring 7.2 is arranged in the sealing groove 7.1, and a fixing frame 7.3 for fixing the sealing ring 7.2 is clamped on the inner cover 1.2. The fixing frame 7.3 abuts against the sealing ring 7.2, increasing the sealing performance between the inner cover 1.2 and the cooking cup.

[0060] This specific embodiment is only an interpretation of the present invention and does not limit the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
