Description

Technical Field

[0001] The utility model relates to the technical field of cutter tools, and in particular to a cutter sheath, a cutter component and a food processor. Background Art

[0002] After using and cleaning the cooking equipment, users usually put a protective cover on the blade. The protective cover is usually provided with a groove structure. During the process of inserting the blade into the protective cover, if the blade is tilted relative to the protective cover, the blade may pass through the groove structure, thereby posing a risk of cutting the user. Utility Model Content

[0003] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0004] In view of this, in the first aspect, the utility model proposes a knife sleeve, which is used for a tool assembly, and the knife sleeve comprises: a knife sleeve body and a first retaining rib, a first slot hole is provided on the first side of the knife sleeve body, the first retaining rib is connected to the knife sleeve body, and a gap is formed between the first side of the knife sleeve body and the first retaining rib for the blade to pass through, wherein the first slot hole is provided with at least one bending section.

[0005] When the tool needs to be protected, the blade is inserted into the knife sleeve. The first retaining rib is arranged on the knife sleeve body, the first retaining rib is directly opposite to the first side of the knife sleeve body, and the first retaining rib is spaced from the knife sleeve body, so that a gap for inserting the blade is formed between the first retaining rib and the knife sleeve body.

[0006] A bending section is formed on the first slot hole, so that the first slot hole is not a long strip structure, but has a bent or bent structure. Therefore, the inner wall of the first slot hole is not a straight structure, but a special-shaped structure. During the process of installing the blade into the knife sleeve, even if the blade is deflected relative to the knife sleeve, the partially bent inner wall of the first slot hole can block the end of the blade, making it difficult for the blade to pass through the knife sleeve through the first slot hole, thereby avoiding the problem of the blade cutting the user during the installation of the knife sleeve, thereby ensuring the safety of the user's use of the tool assembly.

[0007] In addition, the knife sheath in the above technical solution provided by the utility model may also have the following additional technical features:

[0008] In some technical schemes, optionally, the first slot includes multiple sub-slots, and any two adjacent sub-slots are bent toward each other. The length of at least a portion of the multiple sub-slots in the width direction of the blade sleeve is L1, and the width of the second end of the blade is L2. L1 and L2 satisfy that L1≤L2.

[0009] The first slot includes multiple sections of sub-slots, which are connected in sequence, and two adjacent sub-slots are bent relative to each other, that is, the extension directions of the two adjacent sub-slots are different, so the first slot is not a long strip structure, but a multi-segment structure. Moreover, the length of at least a portion of the sub-slots in the width direction of the knife sleeve is less than or equal to the width of the end of the blade. When the blade is inserted into the knife sleeve, the extension length of some sub-slots in the width direction of the knife sleeve is not enough for the end of the blade to pass through, and the blade is not easy to pass out of the knife sleeve from the first slot, so that the problem of the blade cutting the user during the installation of the knife sleeve is avoided, and the user's safety in using the tool assembly is ensured.

[0010] In some technical solutions, optionally, the first retaining rib includes a plurality of sub-rib bodies connected in sequence, the extension directions of two adjacent sub-rib bodies are different, and one sub-rib body is arranged opposite to one sub-slot hole.

[0011] The first slot hole includes a plurality of sub-slot holes, so that the first slot hole has a multi-section structure. In order to ensure that the first slot hole and the first retaining rib can effectively limit the blade, the first retaining rib is also set to a multi-section structure, that is, the first retaining rib includes a plurality of sub-rib bodies, and a sub-rib body is arranged opposite to a sub-slot hole. The first retaining rib has the same structure as the first slot hole, which is beneficial to improving the limiting effect on the blade, preventing the blade from passing through the knife sleeve, and ensuring the safety of the user when using the tool assembly.

[0012] In some technical solutions, optionally, the included angle between two adjacent sub-slots is α, and α satisfies 45°<α<135°.

[0013] Although two adjacent sub-slot holes extend in different directions, when the angle between the two adjacent sub-slot holes is too small or too large, the inner walls of the two adjacent sub-slot holes have a poor limiting effect on the blade, and the end of the blade may pass through the two adjacent sub-slot holes and out of the knife sleeve. In order to avoid the above situation, the angle α between the two adjacent sub-slot holes is limited to 45°<α<135°. Within this range, when the end of the blade passes through two adjacent sub-slot holes at the same time, the inner walls of the two adjacent sub-slot holes block the end of the blade, so that the end of the blade cannot pass through the two adjacent sub-slot holes at the same time, thereby preventing the blade from extending out of the knife sleeve.

[0014] In some technical solutions, optionally, the first retaining rib is arranged opposite to the first slot.

[0015] When the second end of the blade passes through the first slot, one side of the blade is the first slot, and the other side of the blade is the first retaining rib. The first slot limits one side of the blade, and the first retaining rib limits the other side of the blade, so that both sides of the blade cannot pass through the knife sheath, which is conducive to the stable installation of the blade in the knife sheath, avoiding the blade from cutting the user, and ensuring the safety of the user when using the tool assembly.

[0016] In some technical schemes, optionally, the tool sleeve body includes an outer arc side and an inner arc side, the arc length of the outer arc side is greater than the arc length of the inner arc side, the first end of the first retaining rib is connected to the outer arc side, and the second end of the first retaining rib is connected to the inner arc side, and the tool sleeve has an entrance end, from the first end of the first retaining rib to the second end of the first retaining rib, the first retaining rib is inclined in a direction away from the entrance end; from the first end of the first slot hole to the second end of the first slot hole, the first slot hole is inclined in a direction away from the entrance end.

[0017] The knife sleeve body is an arc-shaped structure, wherein the outer side of the knife sleeve body is the outer arc side, and the inner side of the knife sleeve body is the inner arc side. The first end of the first retaining rib is connected to the outer arc side, and the second end of the first retaining rib is connected to the inner arc side. The first end of the first retaining rib is closer to the entrance end of the knife sleeve body, so that the first retaining rib is tilted along the extension direction of the entrance end. Since the first retaining rib is arranged opposite to the first slot, the first slot is also tilted along with the first retaining rib. When the blade is inserted into the knife sleeve, there is a misalignment angle between the end of the blade and the inclined first slot, so that the first slot has a more effective limiting effect on the end of the blade, so that the end of the blade is not easy to extend out of the knife sleeve along the first slot, further improving the user's safety in using the tool assembly.

[0018] In some technical schemes, optionally, the bending section is stepped, and there are multiple bending sections. From the first end of the first retaining rib to the second end of the first retaining rib, the multiple bending sections rise or fall in a step-like manner; from the first end of the first slot hole to the second end of the first slot hole, the first slot hole rises or falls in a step-like manner.

[0019] The multiple bending sections are distributed in a stepped manner. As the blade is inserted into the tool sleeve, the blade will gradually pass through bending sections at different positions during the insertion process. That is, the blade will not pass through multiple bending sections at the same time. This can prevent the blade from extending out of the tool sleeve along adjacent bending sections, further improving the user's safety in using the tool assembly.

[0020] In some technical solutions, optionally, the cross-sectional area of ​​the first retaining rib is set to S1, the opening area of ​​the first slot is set to S2, and S1 and S2 satisfy S1≤S2.

[0021] The cross-sectional area of ​​the first retaining rib is smaller than or equal to the opening area of ​​the first slot, so the blade is not easily obstructed by the first retaining rib during insertion and removal of the blade from the blade sleeve, making the insertion and removal process of the blade more convenient.

[0022] In some technical solutions, optionally, a second slot is further provided on the second side of the knife sleeve body; the knife sleeve also includes: a second rib connected to the knife sleeve body, the second slot is arranged opposite to the second rib, the second rib is spaced apart from the first rib, and a gap is formed between the first side of the knife sleeve body and the second rib for the blade to pass through.

[0023] The first retaining rib and the second retaining rib are installed on the knife sleeve body, and the first retaining rib and the second retaining rib are spaced apart from the knife sleeve body so that the blade can be smoothly inserted into the knife sleeve. The first retaining rib and the second retaining rib are distributed at different positions on the knife sleeve body so that the first retaining rib and the second retaining rib can limit the blade at different positions to prevent the blade from extending out of the knife sleeve.

[0024] In some technical solutions, optionally, the knife sleeve has an inlet end, and the distance between the first retaining rib and the inlet end is smaller than the distance between the second retaining rib and the inlet end.

[0025] The distance between the first retaining rib and the entrance end is small, and the distance between the second retaining rib and the entrance end is large, that is, the first retaining rib is closer to the entrance end of the blade. When the blade is just inserted into the knife sleeve, the blade is more likely to tilt relative to the knife sleeve. The first retaining rib and the first slot are used to limit the blade to ensure that the blade is stably inserted into the knife sleeve. After a part of the blade is inserted into the knife sleeve, it is difficult for the blade to tilt relative to the knife sleeve. At this time, the blade can be limited by the second retaining rib, and the second retaining rib does not need to be set as a special-shaped structure, thereby reducing the processing difficulty of the second retaining rib.

[0026] In some technical solutions, optionally, the thickness of the first barrier rib is greater than or equal to the thickness of the second barrier rib.

[0027] The first retaining rib is a special-shaped structure, which makes it easy to deform. The thickness of the first retaining rib can be appropriately increased to ensure that the first retaining rib has sufficient structural strength and the structural stability of the tool sleeve.

[0028] In a second aspect, the utility model provides a tool assembly, comprising: a blade; and a knife sleeve as in the first aspect, the knife sleeve being used to be sleeved on the blade.

[0029] In a third aspect, the utility model provides a food processor, comprising: a knife assembly as in the second aspect.

DETAILED DESCRIPTION

[0038] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0040] Refer to the following Figures 1 to 4 The present invention describes a knife sheath, a knife assembly and a food processor provided according to some embodiments of the present invention.

[0041] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in an embodiment of the utility model, a knife sleeve 130 is proposed. The knife sleeve 130 is used for a tool assembly 100. The tool assembly 100 includes a blade 120. The knife sleeve 130 includes a knife sleeve body 131 and a first retaining rib 132. A first slot 133 is provided on the first side of the knife sleeve body 131. The first retaining rib 132 is connected to the knife sleeve body 131. A gap is formed between the first side of the knife sleeve body 131 and the first retaining rib 132 for the blade 120 to pass through. Among them, at least one bending section 139 ( Figure 4 The area within the dotted circle is the bending section 139).

[0042] When the knife needs to be protected, the blade 120 is inserted into the knife sleeve 130. The first retaining rib 132 is arranged on the knife sleeve body 131, the first retaining rib 132 is directly opposite to the first side of the knife sleeve body 131, and the first retaining rib 132 is spaced from the knife sleeve body 131, so that a gap for inserting the blade 120 is formed between the first retaining rib 132 and the knife sleeve body 131.

[0043] The first slot 133 is provided with a bending section, so that the first slot 133 is not a long strip structure, but has a bent or folded structure, so the inner wall of the first slot 133 is not a straight structure, but a special-shaped structure. During the installation of the blade 120 into the knife sleeve 130, even if the blade 120 is deflected relative to the knife sleeve 130, the part of the bent inner wall of the first slot 133 can block the end of the blade 120, so that the blade 120 is not easy to pass through the knife sleeve 130 through the first slot 133, avoiding the problem of the blade 120 cutting the user during the installation of the knife sleeve 130, and ensuring the safety of the user in using the tool assembly 100. The problem of the blade 120 being inserted into the knife sleeve 130 by mistake, which causes the user to be cut, can be solved.

[0044] In the related art, because the existing knife sheath has a long straight groove on the structure of the card stock, it is easy for the head of the blade to penetrate easily and penetrate very deeply, causing cuts to the user. In this embodiment, the straight groove structure is changed into an irregular pattern, and its shortest side dimension is made as smaller than the front end width of the knife head as possible. In this way, no matter how the user mistakenly operates, the groove of the card stock will not be penetrated, which will effectively solve the problem of cutting the user caused by the penetration of the blade.

[0045] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, optionally, the first slot 133 includes a plurality of sub-slots 135, and two adjacent sub-slots 135 are bent relative to each other, and at least a portion of the sub-slots 135 in the plurality of sub-slots 135 are arranged in the width direction of the knife sleeve 130 ( Figure 4 The arrow at c in the figure points to the width direction of the knife sleeve 130 ), and the length in the width direction of the knife sleeve 130 is L1. The width of the second end of the blade 120 is L2. L1 and L2 satisfy that L1≤L2.

[0046] The first slot 133 includes multiple sections of sub-slots 135, which are connected in sequence, and two adjacent sub-slots 135 are bent relative to each other, that is, the extension directions of the two adjacent sub-slots 135 are different, so the first slot 133 is not a long strip structure, but a multi-segment structure. Moreover, the length of at least a portion of the sub-slots 135 in the width direction of the knife sleeve 130 is less than or equal to the width of the end of the blade 120. When the blade 120 is inserted into the knife sleeve 130, the extension length of some sub-slots 135 in the width direction of the knife sleeve 130 is not enough for the end of the blade 120 to pass through, and the blade 120 is not easy to pass out of the knife sleeve 130 through the first slot 133, so that the problem of the blade 120 cutting the user during the installation of the knife sleeve 130 is avoided, and the user's safety in using the tool assembly 100 is ensured.

[0047] Figure 4 In the embodiment, the number of the sub-slot holes 135 is 5, namely a first sub-slot hole 1351 , a second sub-slot hole 1352 , a third sub-slot hole 1353 , a fourth sub-slot hole 1354 and a fifth sub-slot hole 1355 .

[0048] In other embodiments, the shape of the first slot 133 may also be a continuous curved structure, or a mixed structure of a curve and a straight line.

[0049] Combination Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, optionally, the first retaining rib 132 includes a plurality of sub-rib bodies 136 connected in sequence, the extension directions of two adjacent sub-rib bodies 136 are different, and one sub-rib body 136 is arranged opposite to one sub-slot hole 135 .

[0050] The first slot 133 includes a plurality of sub-slots 135, so that the first slot 133 is a multi-section structure. In order to ensure that the first slot 133 and the first retaining rib 132 can effectively limit the blade 120, the first retaining rib 132 is also set to a multi-section structure, that is, the first retaining rib 132 includes a plurality of sub-rib bodies 136, and a sub-rib body 136 is arranged opposite to a sub-slot 135. The first retaining rib 132 has the same structure as the first slot 133, which is beneficial to improving the limiting effect on the blade 120, preventing the blade 120 from passing through the knife sleeve 130, and ensuring the safety of the user when using the tool assembly 100.

[0051] In some embodiments, optionally, the included angle between two adjacent sub-slots 135 is α, and α satisfies 45°<α<135°.

[0052] Although two adjacent sub-slot holes 135 extend in different directions, when the angle between the two adjacent sub-slot holes 135 is too small or too large, the inner walls of the two adjacent sub-slot holes 135 have a poor limiting effect on the blade 120, and the end of the blade 120 may pass through the two adjacent sub-slot holes 135 to pass through the knife sleeve 130. In order to avoid the above situation, the angle α between the two adjacent sub-slot holes 135 is limited to meet 45°<α<135°. Within this range, when the end of the blade 120 passes through the two adjacent sub-slot holes 135 at the same time, the inner walls of the two adjacent sub-slot holes 135 block the end of the blade 120, so that the end of the blade 120 cannot pass through the two adjacent sub-slot holes 135 at the same time, thereby preventing the blade 120 from extending out of the knife sleeve 130.

[0053] like Figure 3 As shown, in some embodiments, optionally, the first retaining rib 132 is arranged opposite to the first slot hole 133 .

[0054] When the second end of the blade 120 passes through the first slot 133, one side of the blade 120 is the first slot 133, and the other side of the blade 120 is the first retaining rib 132. The first slot 133 limits one side of the blade 120, and the first retaining rib 132 limits the other side of the blade 120, so that both sides of the blade 120 cannot pass through the knife sleeve 130, which is conducive to the stable installation of the blade 120 into the knife sleeve 130, avoiding the blade 120 from cutting the user, and ensuring the safety of the user when using the tool assembly 100.

[0055] In some embodiments, optionally, the knife sleeve body 131 includes an outer arc side 1311 and an inner arc side 1312, the arc length of the outer arc side 1311 is greater than the arc length of the inner arc side 1312, the first end of the first retaining rib 132 is connected to the outer arc side 1311, and the second end of the first retaining rib 132 is connected to the inner arc side 1312, and the knife sleeve 130 has an inlet end 140, and from the first end of the first retaining rib 132 to the second end of the first retaining rib 132, the first retaining rib 132 is inclined in a direction away from the inlet end 140. From the first end of the first slot hole 133 to the second end of the first slot hole 133, the first slot hole 133 is inclined in a direction away from the inlet end 140.

[0056] The knife sleeve body 131 is an arc-shaped structure, wherein the outer side of the knife sleeve body 131 is an outer arc side 1311, and the inner side of the knife sleeve body 131 is an inner arc side 1312. The first end of the first retaining rib 132 is connected to the outer arc side 1311, and the second end of the first retaining rib 132 is connected to the inner arc side 1312. The first end of the first retaining rib 132 is closer to the inlet end 140 of the knife sleeve body 131, so that the first retaining rib 132 is designed to be inclined along the extension direction of the inlet end 140. Since the first retaining rib 132 is arranged opposite to the first slot 133, the first slot 133 is also designed to be inclined along with the first retaining rib 132. When the blade 120 is inserted into the knife sleeve 130, there is a misalignment angle between the end of the blade 120 and the inclined first slot 133, so that the first slot 133 has a more effective limiting effect on the end of the blade 120, making it difficult for the end of the blade 120 to extend out of the knife sleeve 130 along the first slot 133, further improving the user's safety in using the tool assembly 100.

[0057] In some embodiments, the bending section 139 is optionally stepped, and there are multiple bending sections 139. From the first end of the first retaining rib 132 to the second end of the first retaining rib 132, the multiple bending sections 139 are stepped up or stepped down. From the first end of the first slot 133 to the second end of the first slot 133, the first slot 133 is stepped up or stepped down.

[0058] The multiple bending sections 139 are distributed in a stepped manner. As the blade 120 is inserted into the knife sleeve 130, the blade 120 will gradually pass through the bending sections 139 at different positions during the insertion process. That is, the blade 120 will not pass through multiple bending sections 139 at the same time. This can prevent the blade 120 from extending out of the knife sleeve 130 along adjacent bending sections 139, further improving the user's safety in using the tool assembly 100.

[0059] In some embodiments, optionally, the cross-sectional area of ​​the first retaining rib 132 is set to S1, the opening area of ​​the first slot 133 is set to S2, and S1 and S2 satisfy S1≤S2.

[0060] The cross-sectional area of ​​the first retaining rib 132 is smaller than or equal to the opening area of ​​the first slot 133 . The blade 120 is not easily obstructed by the first retaining rib 132 during insertion and removal of the blade 120 into the blade sleeve 130 , making the insertion and removal of the blade 120 more convenient.

[0061] Combination Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, optionally, a second slot 137 is further provided on the second side of the knife sleeve body 131. The knife sleeve 130 further includes: a second retaining rib 138, the second retaining rib 138 is connected to the knife sleeve body 131, the second slot 137 and the second retaining rib 138 are arranged opposite to each other, the second retaining rib 138 is arranged at intervals from the first retaining rib 132, and a gap is formed between the first side of the knife sleeve body 131 and the second retaining rib 138 for the blade 120 to pass through.

[0062] The first retaining rib 132 and the second retaining rib 138 are installed on the knife sleeve body 131, and the first retaining rib 132 and the second retaining rib 138 are spaced apart from the knife sleeve body 131, so that the blade 120 can smoothly extend into the knife sleeve 130. The first retaining rib 132 and the second retaining rib 138 are distributed at different positions on the knife sleeve body 131, so that the first retaining rib 132 and the second retaining rib 138 can limit the blade 120 at different positions to prevent the blade 120 from extending out of the knife sleeve 130.

[0063] In this embodiment, the second slot hole 137 and the second retaining rib 138 are straight strip structures.

[0064] Combination Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, optionally, the knife sleeve 130 has an inlet end 140 , and the distance between the first retaining rib 132 and the inlet end 140 is smaller than the distance between the second retaining rib 138 and the inlet end 140 .

[0065] The distance between the first retaining rib 132 and the inlet end 140 is small, and the distance between the second retaining rib 138 and the inlet end 140 is large, that is, the first retaining rib 132 is closer to the inlet end 140 of the blade 120. When the blade 120 is just inserted into the knife sleeve 130, the blade 120 is more likely to tilt relative to the knife sleeve 130. The first retaining rib 132 and the first slot 133 are used to limit the blade 120, ensuring that the blade 120 is stably inserted into the knife sleeve 130. After a part of the blade 120 is inserted into the knife sleeve 130, it is difficult for the blade 120 to tilt relative to the knife sleeve 130. At this time, the blade 120 can be limited by the second retaining rib 138, and the second retaining rib 138 does not need to be set as a special-shaped structure, thereby reducing the processing difficulty of the second retaining rib 138.

[0066] In some embodiments, optionally, the thickness of the first barrier rib 132 is greater than or equal to the thickness of the second barrier rib 138 .

[0067] The first retaining rib 132 is a special-shaped structure, which makes it easy for the first retaining rib 132 to deform. The thickness of the first retaining rib 132 can be appropriately increased to ensure that the first retaining rib 132 has sufficient structural strength and ensure the structural stability of the knife sleeve 130.

[0068] In an embodiment of the present utility model, a tool assembly 100 is provided, comprising: a blade 120 and a knife sleeve 130 in any of the above embodiments, wherein the knife sleeve 130 is used to be sleeved on the blade 120 .

[0069] In a possible application, the tool assembly 100 further includes a mounting member 110 , and the blade 120 is disposed on the mounting member 110 . For example, the mounting member 110 is a knife shaft.

[0070] In an embodiment of the present utility model, a food processor is proposed, comprising: a knife assembly as in the above embodiment, and can achieve the same technical effect, which will not be described in detail here.
