Description

Technical Field

[0001] This utility model belongs to the field of cooking utensil technology, specifically relating to a cooking utensil equipped with a packaging breaking mechanism. Background Technology

[0002] Currently, cooking utensils used to make waffles and other types of pancakes mainly consist of a baking pan and molds mounted on it. Before cooking, users need to manually prepare the batter, typically by mixing the batter in a mixing bowl before pouring it into the molds. This process requires significant time and effort from the user, including preparing the batter and cleaning the mixing bowl, resulting in a poor user experience. Therefore, to meet market demand, it is necessary to develop a cooking utensil that can produce waffles and other types of pancakes using a pre-packaged batter. Furthermore, this utensil should also have an automatic function to open the pre-packaged batter. Utility Model Content

[0003] This utility model provides a cooking utensil with a packet-breaking mechanism, which aims to solve the problem that existing cooking utensils used for making pancakes cannot produce pancakes using a batter packet and also lack the function of breaking the packet.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A cooking utensil equipped with a packaging breaking mechanism includes:

[0006] The machine body is equipped with a material bag placement cavity;

[0007] A cooking apparatus, comprising a cooking chamber and a material inlet communicating with the cooking chamber; and,

[0008] A bag-breaking mechanism is disposed between the output end of the bag placement cavity and the material inlet, and the bag-breaking mechanism is used to break an opening in the bag.

[0009] A further solution: The package breaking mechanism includes:

[0010] Two shear heads, each with a shearing portion, are respectively positioned on opposite sides of the material bag, and each shearing portion includes a shearing position close to each other for cutting the material bag and a resetting position far apart from each other and detached from the material bag; and,

[0011] A drive mechanism is connected to the two scissor heads and is used to drive the cutting portions on the two scissor heads to switch between a cutting position and a reset position.

[0012] A further solution: The above configuration allows the drive mechanism to move the two shearing parts to the shearing position to cut an opening in the ingredient bag, so that the batter inside the ingredient bag can fall into the cooking cavity through the opening.

[0013] A further solution: a cooking utensil equipped with a package-breaking mechanism, further comprising a blade shaft, wherein both scissor heads are rotatably connected to the blade shaft;

[0014] When the two shearing parts switch from the reset position to the shearing position, the driving mechanism drives the shearing parts on the two shear heads to rotate toward each other; when the two shearing parts switch from the shearing position to the reset position, the driving mechanism drives the shearing parts on the two shear heads to rotate toward each other and away from each other.

[0015] A further embodiment: Each of the scissor heads is provided with a guide portion at the end away from the cutting part; the driving mechanism includes a drive motor, a lead screw, and a nut seat; the output shaft of the drive motor is driven and connected to the lead screw; the nut seat is threadedly connected to the lead screw; the nut seat is provided with two driving portions; and the two driving portions are slidably connected to the two guide portions respectively.

[0016] When the two shearing parts switch from the reset position to the shearing position, the drive motor drives the nut seat to move toward the two shear heads via the lead screw. The nut seat causes the two drive parts to slide along the two guides respectively, and the shearing parts on the two shear heads rotate toward each other. When the two shearing parts switch from the shearing position to the reset position, the drive motor drives the nut seat to move away from the two shear heads via the lead screw. The nut seat causes the two drive parts to slide along the two guides respectively, and the shearing parts on the two shear heads rotate toward each other.

[0017] Based on the above technical solution: the drive motor drives the shearing parts on the two scissor heads to switch between the shearing position and the reset position through the lead screw and nut seat, so that the linear motion of the nut seat is converted into the opening and closing motion of the two scissor heads, thereby forming a more stable cooperation.

[0018] A further embodiment: the nut seat is provided with a switch triggering part, the body is provided with a first micro switch and a second micro switch, and the first micro switch and the second micro switch are respectively located on opposite sides of the switch triggering part;

[0019] When the drive motor drives the nut seat to move toward the first micro switch via the lead screw, the nut seat drives the two drive parts to slide along the two guide parts respectively, causing the shearing parts on the two scissor heads to rotate toward the direction of mutual approach. When the switch triggering part triggers the first micro switch, the drive motor stops, and the two shearing parts switch to the shearing position.

[0020] When the drive motor drives the nut seat to move toward the second micro switch via the lead screw, the nut seat drives the two drive parts to slide along the two guide parts respectively, causing the shearing parts on the two scissor heads to rotate in a direction away from each other. When the switch triggering part triggers the second micro switch, the drive motor stops, and the two shearing parts switch to the reset position.

[0021] Based on the above technical solution: by setting a switch trigger, a first micro switch and a second micro switch, the drive motor can accurately control the two shearing parts to move to the shearing position or the reset position.

[0022] A further embodiment: the driving part is a rotating shaft, the guiding part is a guide groove, and the rotating shaft is located in the corresponding guide groove.

[0023] A further embodiment: Two supports are arranged side by side on the nut seat, each support including an upper support arm on the upper side and a lower support arm on the lower side, each pivot is rotatably connected to its corresponding upper and lower support arms, and each scissor head is located between its corresponding upper and lower support arms.

[0024] Based on the above technical solution: the above configuration enables the lower support arm and the upper support arm to play a certain limiting role on the scissor head, making the cooperation between the two shearing parts more stable.

[0025] A further embodiment: Each of the scissor heads is provided with a pre-clamping block for clamping the material bag, the pre-clamping block is slidably disposed on the corresponding scissor head, and an elastic reset member is provided between the pre-clamping block and its corresponding scissor head; the two pre-clamping blocks include a clamping position that is close to each other and used to clamp the material bag, and a releasing position that is far apart from each other and used to release the material bag.

[0026] During the process of the driving mechanism driving the two shearing parts to switch from the reset position to the shearing position, the order in which the two pre-clamping blocks switch to the clamping position precedes the order in which the two shearing parts switch to the shearing position; during the process of the driving mechanism driving the two shearing parts to switch from the shearing position to the reset position, the order in which the two shearing parts move away from each other precedes the order in which the two pre-clamping blocks move away from each other.

[0027] Based on the above technical solution: when the package is sheared, the two pre-clamping blocks clamp and position the package before the two shearing parts. Then, the two shearing parts switch to the shearing position to shear the package. This can prevent the package from shifting during the shearing process and make the shearing of the package by the two shearing parts more stable. When resetting, the two shearing parts separate first, and then the two pre-clamping blocks move away from each other. This not only solves the problem of tearing when shearing flexible packages, but also prevents the paste inside the package from flowing out and contaminating the shearing parts. The pre-clamping and shearing are linked, and the elastic resetting component allows the two pre-clamping blocks to dynamically adjust the clamping force during the shearing process, thereby adapting to packaging films of different thicknesses.

[0028] A further embodiment: each of the scissor heads is provided with a slot on its upper side, and the pre-clamping block is provided with a plug-in post. Each plug-in post is slidably inserted into the corresponding slot, and the plug-in post is provided with a limiting part to prevent the plug-in post from axially disengaging from the slot.

[0029] Based on the above technical solution, the above settings make the sliding connection between the pre-clamping block and the scissor head more stable.

[0030] A further embodiment: the elastic reset element is a spring, which is sleeved on the corresponding insertion post and the two ends of the spring are located between the pre-clamping block and the bottom wall of the slot.

[0031] Based on the above technical solution: the above settings facilitate the installation of springs and make the switching between the clamping and releasing positions of the pre-clamping block more stable.

[0032] The beneficial effects of this utility model are as follows:

[0033] In this invention, a material packet placement cavity is provided on the machine body, allowing users to add a pre-filled material packet containing batter into the cavity. Then, a packet-breaking mechanism creates an opening in the material packet, allowing the batter to enter the material inlet of the cooking mechanism. Since users do not need to manually create the opening in the material packet, safety is enhanced. By using pre-filled batter packets to produce waffles and other types of cakes, the time spent by users manually preparing the batter and cleaning the mixing bowl is saved, resulting in a better user experience and making this invention suitable for widespread application.

Detailed Implementation

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0045] like Figures 1 to 5 As shown, this embodiment provides a cooking utensil equipped with a packaging breaking mechanism, including:

[0046] The machine body 1 is provided with a material bag placement cavity 11, which can be used to add a material bag 13 pre-filled with flour paste. The output end of the material bag placement cavity 11 is provided with a material bag 13 outlet, so that the sealed end of the material bag 13 is exposed at the material bag 13 outlet, thereby facilitating the breaking mechanism to break the opening.

[0047] The cooking mechanism 12 includes a cooking chamber 121 and a material inlet 122 communicating with the cooking chamber 121. When the packaging breaking mechanism breaks an opening in the material bag 13, the batter inside the material bag 13 falls through the broken opening into the material inlet 122, and then flows into the cooking chamber 121; and,

[0048] The bag-breaking mechanism is located between the output end of the bag placement cavity 11 and the material inlet 122. The bag-breaking mechanism is used to break an opening in the bag 13. The opening can be made by shearing, piercing, or other methods.

[0049] In some specific implementations, such as Figures 1 to 6 As shown, the package breaking mechanism includes:

[0050] Two scissor heads 2, each equipped with a cutting section 21, are respectively positioned on opposite sides of the ingredient package 13. Each cutting section 21 includes a cutting position close to each other and used to cut the ingredient package 13, and a resetting position far apart from each other and detached from the ingredient package 13. Specifically, in the cutting position, the two cutting sections 21 interlock to cut open the sealed end of the ingredient package 13. A preferred solution is to not cut completely, or to cut 90% of the way open, thereby preventing the completely cut portion from falling into the cooking cavity 121; and...

[0051] A drive mechanism is drivenly connected to the two scissor heads 2 and is used to drive the cutting parts 21 on the two scissor heads 2 to switch between a cutting position and a reset position.

[0052] In some specific implementations, such as Figures 1 to 6 As shown, a cooking utensil with a pack-breaking mechanism also includes a blade shaft 26, and both scissor heads 2 are rotatably connected to the blade shaft 26; that is, the drive mechanism drives the two scissor heads 2 to rotate relative to the blade shaft 26, thereby causing the two cutting parts 21 to switch between a cutting position and a reset position.

[0053] When the two shearing parts 21 switch from the reset position to the shearing position, the driving mechanism drives the shearing parts 21 on the two scissor heads 2 to rotate toward each other; when the two shearing parts 21 switch from the shearing position to the reset position, the driving mechanism drives the shearing parts 21 on the two scissor heads 2 to rotate toward each other and move away from each other.

[0054] In some specific implementations, such as Figures 1 to 6 As shown, each of the scissor heads 2 has a guide portion 22 at one end away from the cutting part 21. The driving mechanism includes a drive motor 3, a lead screw 31, and a nut seat 32. The output shaft of the drive motor 3 is drivenly connected to the lead screw 31. The lead screw 31 is rotatably connected to the machine body 1 through a bearing. The nut seat 32 is threadedly connected to the lead screw 31. The nut seat 32 has two driving parts 321, and the two driving parts 321 are slidably connected to the two guide portions 22 respectively.

[0055] When the two shearing parts 21 switch from the reset position to the shearing position, the drive motor 3 drives the nut seat 32 to move toward the two shear heads 2 via the lead screw 31. The nut seat 32 drives the two drive parts 321 to slide along the two guide parts 22 respectively, causing the shearing parts 21 on the two shear heads 2 to rotate toward each other. When the two shearing parts 21 switch from the shearing position to the reset position, the drive motor 3 drives the nut seat 32 to move away from the two shear heads 2 via the lead screw 31. The nut seat 32 drives the two drive parts 321 to slide along the two guide parts 22 respectively, causing the shearing parts 21 on the two shear heads 2 to rotate toward each other.

[0056] Specifically, the guide part 22 can be a guide groove or a guide hole, etc., and the drive part 321 is a rotating shaft 321a that is rotatably connected to the nut seat 32. The rotating shaft 321a is located in the guide groove corresponding to it.

[0057] The nut seat 32 is provided with two brackets 322 arranged side by side, each bracket 322 including an upper support arm 322a on the upper side and a lower support arm 322b on the lower side. Each rotating shaft 321a is rotatably connected to its corresponding upper support arm 322a and lower support arm 322b. Each scissor head 2 is located between its corresponding upper support arm 322a and lower support arm 322b.

[0058] In some specific implementations, such as Figures 3 to 6 As shown, in order to achieve precise control of the switching of the two shearing parts 21 between the shearing position and the reset position, the nut seat 32 is provided with a switch triggering part 323, and the machine body 1 is provided with a first micro switch 14 and a second micro switch 15. The first micro switch 14 and the second micro switch 15 are respectively located on opposite sides of the switch triggering part 323. Specifically, the first micro switch 14 is located on the left side of the switch triggering part 323, and the second micro switch 15 is located on the right side of the switch triggering part 323.

[0059] When the drive motor 3 drives the nut seat 32 to move toward the first micro switch 14 via the lead screw 31, the nut seat 32 drives the two drive parts 321 to slide along the two guide parts 22 respectively, causing the shearing parts 21 on the two scissor heads 2 to rotate toward each other. When the switch trigger part 323 triggers the first micro switch 14, the drive motor 3 stops, and the two shearing parts 21 switch to the shearing position.

[0060] When the drive motor 3 drives the nut seat 32 to move toward the second micro switch 15 via the lead screw 31, the nut seat 32 drives the two drive parts 321 to slide along the two guide parts 22 respectively, causing the shearing parts 21 on the two scissor heads 2 to rotate in a direction away from each other. When the switch trigger part 323 triggers the second micro switch 15, the drive motor 3 stops, and the two shearing parts 21 switch to the reset position.

[0061] In some specific implementations, such as Figures 5 to 7 As shown, in order to enable the two shearing parts 21 to cut the material bag 13 better, each of the shear heads 2 is provided with a pre-clamping block 23 for clamping the material bag 13. The pre-clamping block 23 is slidably disposed on the corresponding shear head 2, and an elastic reset member 25 is provided between the pre-clamping block 23 and its corresponding shear head 2. The two pre-clamping blocks 23 include a clamping position that is close to each other and used to clamp the material bag 13, and a releasing position that is far apart from each other and used to release the material bag 13.

[0062] During the process of the driving mechanism driving the two shearing parts 21 to switch from the reset position to the shearing position, the order in which the two pre-clamping blocks 23 switch to the clamping position is before the order in which the two shearing parts 21 switch to the shearing position. Specifically, the two pre-clamping blocks 23 first perform a pre-clamping action on the material package 13 to clamp and position the material package 13. Then, the two shearing parts 21 shear the material package 13. This can prevent the material package 13 from shifting during the shearing process and also make the shearing of the material package 13 by the two shearing parts 21 more stable.

[0063] During the process of the driving mechanism driving the two shearing parts 21 to switch from the shearing position to the reset position, the order in which the two shearing parts 21 move away from each other precedes the order in which the two pre-clamping blocks 23 move away from each other. Specifically, the two shearing parts 21 first move away from each other. At this time, due to the action of the elastic reset member 25, the two pre-clamping blocks 23 still maintain the clamping position to prevent the slurry in the material bag 13 from flowing out and contaminating the shearing parts 21. Then, as the two shearing parts 21 move further away, the two pre-clamping blocks 23 move away from each other, thereby facilitating the flow of slurry in the material bag 13.

[0064] Each of the scissor heads 2 has a slot 24 on its upper side, and a plug 231 is provided on the pre-clamping block 23. Each plug 231 is slidably inserted into the corresponding slot 24. The plug 231 has a limiting part 232 to prevent the plug 231 from axially disengaging from the slot 24. The limiting part 232 is located at the end of the plug 231 away from the pre-clamping block 23, and is located on the outer side of the bottom wall of the slot 24. Specifically, it can be a sealing sleeve or a protrusion structure.

[0065] The elastic reset member 25 is a spring, which is sleeved on the corresponding insertion post 231 and the two ends of the spring are located between the pre-clamping block 23 and the bottom wall of the slot 24.

[0066] Working principle explanation:

[0067] In use, the user adds a pre-filled batter packet 13 into the batter packet placement cavity 11. Then, the drive mechanism drives the cutting parts 21 on the two scissor heads 2 to move closer together and switch to the cutting position. During this process, the two pre-clamping blocks 23 first pre-clamp the batter packet 13 to clamp and position the sealed end of the batter packet 13. Then, the two cutting parts 21 cut the batter packet 13. After the cutting action is completed, the two cutting parts 21 first move away from each other. At this time, due to the action of the elastic reset member 25, the two pre-clamping blocks 23 still maintain the clamping position to prevent the batter in the batter packet 13 from flowing out and contaminating the cutting parts 21. Then, as the two cutting parts 21 move further away, the two pre-clamping blocks 23 move away from each other, which facilitates the batter in the batter packet 13 to flow out into the cooking cavity 121.

[0068] This utility model is not limited to the above-mentioned optional embodiments. Under the premise of non-contradiction, the various solutions can be combined arbitrarily. Anyone can derive other forms of products under the guidance of this utility model. However, no matter what changes are made in their shape or structure, all technical solutions that fall within the scope of the claims of this utility model are within the protection scope of this utility model.
