Description

Technical Field

[0001] The present application belongs to the technical field of kitchen appliances, and specifically relates to a multifunctional combined chopping board. Background Art

[0002] Currently, most reversible cutting boards on the market are composite cutting boards, with one side made of stainless steel and the other plastic. The two panels are stacked and secured with a rubber band. However, the band is susceptible to wear and tear over time, reducing the board's lifespan. Furthermore, to achieve this, the band protrudes slightly from the outer edge of the panels, creating a blind spot between the band and the outer edge of the panels. After use, the user must be extremely careful to clean the junction between the band and the outer edge of the panels, significantly reducing the user experience.

[0003] The prior art discloses a combined chopping board, comprising a chopping board body, a first adjustment plate, and a second adjustment plate. The chopping board body is provided with a plurality of through holes, the first adjustment plate is provided with a plurality of protrusions, and the second adjustment plate is provided with a plurality of working heads. The first adjustment plate and the second adjustment plate are movably connected to the chopping board body, respectively. The positions of the protrusions correspond one-to-one with the positions of the through holes, and the height of the protrusions is equal to the depth of the through holes, so as to fill the through holes and form a smooth cutting surface. The positions of the working heads correspond one-to-one with the positions of the through holes, and the height of the working heads is greater than the depth of the through holes, so that the working heads can extend beyond the through holes to form a planer. For this type of combined chopping board, it only has a planer usage mode and a flat plate usage mode, and the working surface is the upper surface of the chopping board body.

[0004] In actual application, users have put forward multi-functional and multi-scenario application requirements for chopping boards, such as the need to cut raw and cooked food, chop meat, and the need for anti-slip during the cutting process. The above-mentioned combination chopping board obviously cannot meet the multi-functional usage requirements.

[0005] In addition, during use, the above-mentioned anvil board only relies on the cooperation between the protrusion and the through hole, or the cooperation between the working head and the through hole, as well as the support columns and step portions between the anvil board body and the first adjustment plate and the second adjustment plate to achieve the limitation between the anvil board body and the first adjustment plate, or the anvil board body and the second adjustment plate. The limiting method is single and the limiting angle is effective, thereby limiting the use status of the combined anvil board. Utility Model Content

[0006] The present application provides a multifunctional combined chopping board to solve the technical problem that the existing chopping board has a single function and the limiting structure cannot achieve stable assembly of the combined chopping board.

[0007] The technical solutions adopted in this application are:

[0008] A multifunctional combination chopping board comprises an upper panel and a lower panel, the upper panel being provided with a plurality of through holes, the lower panel being provided with a plurality of protrusions extending upward, the upper panel and the lower panel being detachably connected to each other so as to have a disassembled state and a combined state; in the disassembled state, the upper surface and / or the lower surface of the upper panel constitute a food-carrying surface; in the combined state, the protrusions pass through the through holes and protrude from the upper panel, and the lower surface of the lower panel constitutes a food-carrying surface; the combination chopping board further comprises a limiting member, which connects the upper panel and the lower panel in the combined state to limit the upper panel from being separated from the lower panel.

[0009] The multifunctional combined cutting board in this application also includes the following additional technical features:

[0010] The upper panel is provided with a first mounting groove which passes through in the vertical direction, the lower panel is provided with a second mounting groove which passes through in the vertical direction, and the limiting member is interference fitted in the first mounting groove and the second mounting groove in the vertical direction.

[0011] The first mounting groove is located on the side of the upper panel, and the first mounting groove includes a first through groove and a first notch groove connecting the first through groove and the outside world; the second mounting groove is located on the side of the lower panel, and the second mounting groove includes a second through groove and a second notch groove connecting the second through groove and the outside world; the limiting member includes a first limiting portion passing through the first through groove and the second through groove, and a second limiting portion passing through the first notch groove and the second notch groove.

[0012] A first step abutment surface is formed at the connection position of the first through groove and the first notch groove, and a second step abutment surface is formed at the connection position of the second through groove and the second notch groove. The first limiting portion abuts against the first step abutment surface and the second step abutment surface in the length direction respectively to limit the relative sliding of the upper panel and the lower panel along the length direction.

[0013] The lower panel is provided with a mounting hole for mounting the boss, and the boss is interference fit with the mounting hole.

[0014] The boss includes an anti-slip portion and an extension portion connected to the anti-slip portion to extend through the lower panel and the upper panel. The mounting hole has a first mounting hole adapted to the extension portion, and a second mounting hole adapted to the anti-slip portion. A limiting step is formed at the transition position between the first mounting hole and the second mounting hole to stop the anti-slip portion.

[0015] One of the upper panel and the lower panel is provided with a support column, and the other of the two is provided with a step portion. The support column abuts against the step portion to limit the relative movement of the upper panel and the lower panel along the length direction.

[0016] The upper panel is provided with a guide surface at the through hole; and / or the top of the convex column is provided with a guide surface.

[0017] In the assembled state, there is a clearance fit between the boss and the through hole.

[0018] The upper surface of the upper panel is provided with scale marking lines; and / or the lower surface of the lower panel is provided with scale marking lines.

[0019] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0020] 1. The upper and lower panels of the present application are detachably connected to have a disassembled state and a combined state. In the disassembled state, the upper panel has a food-carrying surface for operations such as cutting food. In the combined state, the lower panel has a food-carrying surface for operations such as cutting food. Different food-carrying surfaces can be provided in different usage states to meet the user's cutting needs for different ingredients. For example, the upper panel can be used to cut cooked food, and the lower panel can be used to cut raw meat, etc. This prevents bacteria, parasite eggs, etc. in the food from remaining on the food-carrying surface when cutting raw food and contaminating the cooked food.

[0021] Furthermore, in the assembled state, the protrusions of the lower panel pass through the through-holes and protrude from the upper panel. This allows the protrusions protruding from the upper panel to contact the countertop supporting the cutting board when the lower surface of the lower panel is used as a food support surface for cutting food, thereby increasing friction between the cutting board and the countertop, preventing the cutting board from slipping during use and ensuring the stability of the cutting board. In the assembled state, when food is placed on the upper surface of the upper panel, the protrusions can be inserted into the food to secure it, preventing it from slipping during cutting and facilitating cutting.

[0022] The arrangement of through-holes on the top panel makes it more breathable, easier to dry after use, and less likely to breed bacteria, providing antibacterial and mildew-proof properties. If food falls into the through-holes during use, the protruding posts can be used to push out food residue, preventing it from remaining inside. This not only reduces the cleaning burden for the user but also prevents bacterial growth.

[0023] Furthermore, in order to ensure that the boss can be smoothly and conveniently inserted into the through hole of the upper panel, there is a gap fit between the boss and the through hole of the upper panel. When the chopping board is in the combined state, the upper panel and the lower panel need to be flipped over as a whole so that the lower surface of the lower panel can be used as the food bearing surface for cutting food. During the flipping process, the upper panel and the lower panel are prone to relative sliding and displacement. Therefore, the chopping board in the present application also includes a limiter connecting the upper panel and the lower panel. When the combined chopping board is flipped in the combined state, the limiter can limit the relative movement between the upper panel and the lower panel, thereby ensuring the stability of the combined state, facilitating the user to quickly and smoothly flip the combined chopping board, and improving the user experience.

[0024] In addition, the presence of the limiter not only limits the upper panel and the lower panel in the combined state to facilitate the smooth flipping of the two, but also during the process of storing, accommodating and moving the combined chopping board, the presence of the limiter can ensure that there is no relative movement between the upper panel and the lower panel, thereby making it easier for users to move and store the combined chopping board.

[0025] 2. As a preferred embodiment of the present application, the limit member is interference fitted in the first mounting groove of the upper panel and the second mounting groove of the lower panel along the up and down directions. The interference fitting method can not only increase the friction between the limit member and the upper panel and the lower panel to ensure stable assembly between the two, but also facilitate the assembly and disassembly of the limit member to achieve rapid switching between the combined state and the disassembled state. Moreover, the assembly and disassembly process of the limit member can be achieved without the aid of tooling, which is convenient and fast, and provides a pleasant user experience.

[0026] Furthermore, the first mounting slot includes a first through slot and a first notch slot, and the second mounting slot includes a second through slot and a second notch slot, both of which are in communication with the outside along the length of the cutting board. The stopper includes a first stopper extending through the first through slot and the second through slot, and a second stopper extending through the first notch slot and the second notch slot, with the second stopper exposed along the length of the cutting board, thereby facilitating force application by the user. Furthermore, after the stopper is removed from the cutting board, it can be held in the user's hand, preventing the stopper from falling or even flying when force is applied only in the up and down directions, which would increase the user's effort in picking up the stopper.

[0027] 3. As a preferred embodiment of the present application, the interference fit between the boss and the mounting hole of the lower panel not only improves the assembly efficiency of the boss and the lower panel, but also ensures the concentricity of the boss, so that when the upper panel and the lower panel are assembled, the boss can be smoothly inserted into the upper panel, avoiding the phenomenon that some bosses have poor concentricity and interfere with the upper panel during the assembly process, thereby affecting the assembly of the upper and lower panels.

[0028] 4. As a preferred embodiment of the present application, one of the upper and lower panels is provided with a support column, and the other is provided with a step portion. The support column and the step portion can abut against each other to limit the relative movement of the upper and lower panels along the length direction. The provision of the support column and the step portion can provide rough positioning for the upper and lower panels during assembly, thereby helping to improve the assembly efficiency of the upper and lower panels.

[0029] 5. As a preferred embodiment of the present application, the upper surface of the upper panel and / or the lower surface of the lower panel are provided with scale marking lines. The setting of the scale marking lines can play a good guiding role when cutting food, thereby improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] In order to more clearly illustrate the overall concept of the present application, a detailed description is given below in an illustrative manner in conjunction with the accompanying drawings.

[0046] The following description sets forth many specific details to facilitate a thorough understanding of the present application.

In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0050] like Figures 1 to 10 As shown, a multifunctional combination chopping board includes an upper panel 1 and a lower panel 2, the upper panel 1 is provided with a plurality of through holes 12, and the lower panel 2 is provided with a plurality of protrusions 22 extending upward, the upper panel 1 and the lower panel 2 can be detachably connected to have a detached state and a combined state; in the detached state, the upper surface and / or the lower surface of the upper panel 1 constitute a food bearing surface; in the combined state, the protrusions 22 pass through the through holes 12 and protrude from the upper panel 1, and the lower surface of the lower panel 2 constitutes a food bearing surface; the combination chopping board also includes a limit member 3, which, in the combined state, connects the upper panel 1 and the lower panel 2 to limit the upper panel 1 from being separated from the lower panel 2.

[0051] This application does not limit the materials of the upper panel 1 and the lower panel 2. In one embodiment, one of the upper panel 1 and the lower panel 2 is a stainless steel plate, and the other is a plastic plate. In another embodiment, both the upper panel 1 and the lower panel 2 are stainless steel plates. In yet another embodiment, one of the upper panel 1 and the lower panel 2 is a wooden plate, and the other is a plastic plate.

[0052] The upper panel 1 and lower panel 2 of the present application are detachably connected, allowing for a disassembled state and a combined state. In the disassembled state, the upper panel 1 provides a food-carrying surface for operations such as cutting food. In the combined state, the lower panel 2 provides a food-carrying surface for operations such as cutting food. Different food-carrying surfaces can be provided in different usage states, thereby meeting the user's cutting needs for different ingredients. For example, the upper panel 1 can be used to cut cooked food, while the lower panel 2 can be used to cut raw meat. This prevents bacteria, parasite eggs, etc. in the raw food from remaining on the food-carrying surface when cutting raw food, thereby contaminating the cooked food.

[0053] Furthermore, in the assembled state, the boss 22 of the lower panel 2 passes through the through hole 12 and protrudes from the upper panel 1. This allows the boss 22 extending from the upper panel 1 to contact the countertop supporting the cutting board when the lower surface of the lower panel 2 is used as a food support surface for cutting food. This increases the friction between the cutting board and the countertop, preventing the cutting board from slipping during use and ensuring the stability of the cutting board. In the assembled state, when food is placed on the upper surface of the upper panel 1, the boss 22 protrudes, allowing it to be inserted into the food to secure it, preventing it from slipping during cutting and facilitating cutting.

[0054] The arrangement of through holes 12 on the upper panel 1 makes the upper panel 1 more breathable, easier to dry after use, and less likely to breed bacteria. If food falls into the through holes 12 during use, the protrusions 22 can be used to push out the food residue, preventing it from remaining in the through holes 12. This not only reduces the cleaning burden on the user but also prevents the growth of bacteria.

[0055] Furthermore, in order to ensure that the boss 22 can be smoothly and conveniently inserted into the through hole 12 of the upper panel 1, there is a clearance fit between the boss 22 and the through hole 12 of the upper panel 1. When the chopping board is in the combined state, the upper panel 1 and the lower panel 2 need to be flipped over as a whole to use the lower surface of the lower panel 2 as the food bearing surface for cutting food. During the flipping process, the upper panel 1 and the lower panel 2 are prone to relative sliding and displacement. Therefore, the chopping board in the present application also includes a limiter 3 connecting the upper panel 1 and the lower panel 2. When the combined chopping board is flipped in the combined state, the limiter 3 can limit the relative movement between the upper panel 1 and the lower panel 2, thereby ensuring the stability of the combined state, facilitating the user to quickly and smoothly flip the combined chopping board, and improving the user experience.

[0056] In addition, the presence of the limiter 3 not only limits the upper panel 1 and the lower panel 2 in the combined state to facilitate smooth flipping of the two, but also during the process of storing, accommodating and moving the combined chopping board, the presence of the limiter 3 can also ensure that there is no relative movement between the upper panel 1 and the lower panel 2, thereby making it easier for users to move and store the combined chopping board.

[0057] The structure of the limiter 3 in this application can adopt any one of the following embodiments:

[0058] Embodiment 1: The limiting member 3 is a binding strap, the upper panel 1 is provided with a first perforation for the binding strap to pass through, and the lower panel 2 is provided with a second perforation for the binding strap to pass through. The binding strap passes through the first perforation and the second perforation and is tied and fixed on one side of the upper panel 1 and the lower panel 2, thereby realizing smooth flipping of the upper panel 1 and the lower panel 2 in the combined state.

[0059] Implementation method 2: The limiting member 3 includes a tongue and a buckle position that can be fixed with the tongue. One of the tongue and the buckle position is provided on the upper panel 1, and the other is provided on the lower panel 2. The upper panel 1 is stacked on the lower panel 2, and the tongue is buckled into the buckle position, thereby realizing the clamping and fixing of the upper panel 1 and the lower panel 2, and realizing the smooth flipping of the upper panel 1 and the lower panel 2 in the combined state.

[0060] Implementation method three: Figures 4 to 10 As shown, the upper panel 1 is provided with a first mounting groove 11 extending vertically, the lower panel 2 is provided with a second mounting groove 21 extending vertically, and the stopper 3 is interference-fitted in the first mounting groove 11 and the second mounting groove 21 in the vertical direction. The interference fit method can not only increase the friction between the stopper 3 and the upper panel 1 and the lower panel 2, ensuring stable assembly between the two, but also facilitate the assembly and disassembly of the stopper 3, thereby achieving rapid switching between the assembled and disassembled states. Moreover, the assembly and disassembly process of the stopper 3 can be achieved without the aid of tooling, which is convenient and quick, and provides a pleasant user experience.

[0061] Preferably, the limit member 3 is a silicone member or a rubber member. On the one hand, it is convenient for the assembly of the limit member 3. On the other hand, when the limit member 3 is assembled to the upper panel 1 and the lower panel 2 in the combined state, the friction between the limit member 3 and the upper panel 1 and the lower panel 2 is large, and it is not easy to slip, thereby ensuring the stability of the combined state.

[0062] In one embodiment, the first mounting groove 11 only penetrates the upper panel 1 along the up-down direction, and the second mounting groove 21 only penetrates the lower panel 2 along the up-down direction, that is, the first mounting groove 11 and the second mounting groove 21 do not extend through the sides of the upper panel 1 and the lower panel 2, and the limit member 3 is installed into or removed from the first mounting groove 11 and the second mounting groove 21 along the up-down direction by pressing.

[0063] In another embodiment, Figure 7 and Figure 10As shown, the first mounting groove 11 is located on the side of the upper panel 1, and the first mounting groove 11 includes a first through groove 111 and a first notch groove 112 connecting the first through groove 111 with the outside world; the second mounting groove 21 is located on the side of the lower panel 2, and the second mounting groove 21 includes a second through groove 211 and a second notch groove 212 connecting the second through groove 211 with the outside world; the limiting member 3 includes a first limiting portion 31 passing through the first through groove 111 and the second through groove 211, and a second limiting portion 32 passing through the first notch groove 112 and the second notch groove 212. In this embodiment, the first notch groove 112 and the second notch groove 212 are both connected to the outside world along the length direction of the anvil. The limiting member 3 includes a first limiting portion 31 passing through the first through groove 111 and the second through groove 211, and a second limiting portion 32 passing through the first notch groove 112 and the second notch groove 212. The second limiting portion 32 is exposed along the length direction of the anvil, so as to facilitate the user to apply force, and the limiting member 3 can be held in the user's hand after being removed from the anvil, avoiding the limiting member 3 from falling or even flying when force is applied only in the up and down directions, which increases the operation of the user to pick up the limiting member 3.

[0064] Furthermore, if Figure 1 、 Figure 3 、 Figure 7 and Figure 10 As shown, a first step abutting surface 113 is formed at the connection position of the first through-groove 111 and the first notch groove 112, and a second step abutting surface 213 is formed at the connection position of the second through-groove 211 and the second notch groove 212. The first limiting portion 31 abuts against the first step abutting surface 113 and the second step abutting surface 213 in the length direction, respectively, to limit the relative sliding of the upper panel 1 and the lower panel 2 along the length direction. The first step abutting surface 113 and the second step abutting surface 213 can form a limit for the limiting member 3 along the length direction of the anvil, preventing the limiting member 3 from falling out of the first notch groove 112 and the second notch groove 212, thereby ensuring the stability of the assembled state.

[0065] In the present application, the connection between the lower panel 2 and the boss 22 may be any of the following embodiments:

[0066] Embodiment 4: The boss 22 is provided with an external thread, the lower panel 2 is provided with a mounting hole 24 , the mounting hole 24 is provided with an internal thread adapted to the external thread of the boss 22 , and the boss 22 is screwed to the lower panel 2 .

[0067] Embodiment 5: The lower panel 2 is provided with a mounting hole 24 for mounting the boss 22, and the boss 22 has an interference fit with the mounting hole 24. Compared with the aforementioned embodiment 4, the assembly of the boss 22 in this embodiment 5 is faster and does not require the use of tooling, which can greatly improve the assembly efficiency of the lower panel 2 and the boss 22.

[0068] Whether it is the fourth embodiment or the fifth embodiment, the connection between the boss 22 and the lower panel 2 is detachable and washable, so that when the side of the boss 22 facing the upper panel 1 is bent during use and affects the next assembly of the upper panel 1 and the lower panel 2, the boss 22 can be removed and replaced, ensuring that the upper panel 1 and the lower panel 2 can be assembled smoothly.

[0069] Furthermore, if Figure 4 and Figure 5 As shown, the boss 22 includes an anti-slip portion 221 and an extension portion 222 connected to the anti-slip portion 221 to extend through the lower panel 2 and the upper panel 1. The mounting hole 24 includes a first mounting hole 241 adapted to the extension portion 222, and a second mounting hole 242 adapted to the anti-slip portion 221. A limiting step 243 is formed at the transition position between the first mounting hole 241 and the second mounting hole 242 to stop the anti-slip portion 221. On the one hand, it can serve as a reminder of the proper assembly process. On the other hand, it can ensure that the depth of each boss 22 inserted into the lower panel 2 is consistent, so that the height of the portion of the boss 22 extending from the lower panel 2 is consistent. In the assembled state, when the cutting board is turned over and the lower surface of the lower panel 2 is used as the food support surface, one end of each boss 22 can contact the table surface on which the cutting board is placed, thereby achieving stable support for the entire cutting board and preventing the cutting board from vibrating in the up and down directions during cutting.

[0070] As a preferred embodiment of the present application, Figure 4 and Figure 5 As shown, one of the upper panel 1 and the lower panel 2 is provided with a support column 13, and the other is provided with a step portion 23. The support column 13 and the step portion 23 abut against each other to limit the relative movement of the upper panel 1 and the lower panel 2 along the longitudinal direction. The provision of the support column 13 and the step portion 23 can provide rough positioning for the upper panel 1 and the lower panel 2 during assembly, thereby helping to improve the assembly efficiency of the upper panel 1 and the lower panel 2.

[0071] As a preference, Figures 4 to 6 As shown, the step portion 23 is provided on the lower panel 2, the support column 13 is provided on the upper panel 1, and the support column 13 extends along the width direction of the upper panel 1 to be basically consistent with the width dimension of the upper panel 1, so that the upper panel 1 can be firmly supported by the support column 13 in the split state, and when the upper panel 1 is used to cut food in the split state, due to the existence of the support column 13, a gap can be created between the upper panel 1 and the table surface where the chopping board is placed, thereby making the upper panel 1 more breathable and achieving quick drying after use.

[0072] As a preferred embodiment of the present application, the upper panel 1 is provided with a guide surface at the through hole 12; and / or a guide surface is provided at the top of the boss 22. This arrangement can provide guidance for the upper panel 1 and the boss 22 during assembly of the upper panel 1 and the lower panel 2, facilitating quick and smooth insertion of the boss 22 into the through hole 12 of the upper panel 1.

[0073] In one embodiment, the inner diameter of the through hole 12 increases sequentially from top to bottom, so as to form a tapered surface on the inner wall surface of the through hole 12 , and the tapered surface constitutes a guide surface.

[0074] As a preferred embodiment of the present application, in the assembled state, there is a clearance fit between the boss 22 and the through hole 12. The clearance fit between the boss 22 and the through hole 12 can reduce the resistance to assembly and disassembly, and achieve rapid assembly and disassembly between the upper panel 1 and the lower panel 2.

[0075] As a preferred embodiment of the present application, Figure 1 and Figure 3 As shown, the upper surface of the upper panel 1 is provided with length scale marking lines 14 along its length direction; and / or, the lower surface of the lower panel 2 is provided with length scale marking lines 14 along its length direction. Figure 1 and Figure 3 As shown, the upper surface of the upper panel 1 is provided with a diameter scale marking 15; and / or the lower surface of the lower panel 2 is provided with a diameter scale marking 15.
