Description

Technical Field

[0001] The utility model belongs to the field of kitchen tools, and particularly relates to a garlic press. Background Art

[0002] A garlic press generally includes a container and a knife rest assembly arranged in the container. A user pulls the knife rest assembly to rotate in the container to crush ingredients such as garlic cloves for use.

[0003] Currently, the common problem of a hand-pulled garlic press is the poor feeling during use when pulling the rope. Specifically, the blocking feeling feedback when pulling the rope is relatively strong. When using, a user needs to apply a relatively large pulling force to use it normally. Problems such as hand soreness and laboriousness are likely to occur during use of the garlic press, affecting the user experience. In addition, some garlic presses also have the problem of slight up-and-down movement of the rotating shaft, resulting in relatively large noise during use, which also affects the user experience.

[0004] Moreover, regarding the problem of strong blocking feeling of the pulling rope, it is found during use that the blocking phenomenon of the pulling rope will be alleviated after removing the cover of the garlic press, while the probability of the blocking phenomenon occurring will increase after reinstalling, resulting in misjudgment by the user and difficulty in determining whether the garlic press is damaged, reducing the user's desire to use. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a garlic press to solve at least one of the above problems.

[0006] To solve the above technical problem, the utility model adopts the following technical solution: A garlic press includes a cup body, an upper cover, and a knife rest assembly arranged in the cup body. The upper cover covers the cup body, the knife rest assembly is clamped between the upper cover and the bottom wall of the cup body, a support protrusion is arranged on the bottom surface of the knife rest assembly, and the knife rest assembly abuts against the bottom wall through the support protrusion; wherein, the area of the support surface of the support protrusion for fitting the bottom wall is M1, and the area of the projection of the bottom surface of the knife rest assembly on the bottom wall is M2, and M1 < M2.

[0007] Analysis shows that the bottom surface of the knife rest assembly in the garlic press fits on the inner bottom wall of the container. When the knife rest assembly rotates, a relatively large frictional force will be generated between the knife rest assembly and the container. While it is laborious for the user to pull, the inner bottom wall of the knife rest assembly and the container will wear against each other, making it laborious to pull, and the plastic chips generated by the wear will be mixed into the crushed ingredients and eaten by the user, damaging the user's physical health and shortening the service life of the garlic press.

[0008] Based on this, the technical solution has the following technical effects:

[0009] In this utility model, by providing support protrusions on the bottom surface of the knife rest assembly, when the knife rest assembly is installed in the cup body, the support protrusions separate the bottom surface of the knife rest assembly from the bottom wall of the cup body. The bottom surface of the knife rest assembly does not directly contact the bottom wall of the cup body, but abuts against the bottom wall of the cup body through the support protrusions. Therefore, the area of the support surface of the support protrusions is smaller than the area of the bottom surface of the knife rest assembly. So, the support protrusions can reduce the contact area between the knife rest assembly and the bottom wall of the cup body. When the knife rest assembly rotates, the friction between the knife rest assembly and the cup body can be reduced, making it more labor-saving for the user to pull the knife rest assembly to rotate, enhancing the user experience. At the same time, the reduction of the contact area between the knife rest assembly and the bottom wall of the cup body can also greatly reduce the wear between the knife rest assembly and the cup body, prolonging the service life of the garlic press.

[0010] In the above-mentioned garlic press, the support protrusions are annular ribs, and the fitting mode between the annular ribs and the bottom wall is line contact. This greatly reduces the contact area between the bottom of the annular ribs and the bottom wall of the cup body, minimizing the influence of the friction between the annular ribs and the cup body on the rotation of the knife rest assembly, making it more labor-saving for the user to pull the knife rest assembly to rotate. It should be noted that the line contact described here should be understood in a broad sense, for example, it can be contact with the bottom wall through a very small micro-surface. Due to processing errors, it is impossible to process a linear structure without width in practice, so the line contact should be understood in a broad sense.

[0011] In the above-mentioned garlic press, the annular ribs are arranged around the central axis of the knife rest assembly, and the surface of the annular ribs that fits with the bottom wall is a convex arc surface facing the bottom wall. The central axis of the annular ribs coincides with the central axis of the knife rest assembly, enabling the annular ribs to stably support the bottom surface of the knife rest assembly. When the user pulls the knife rest assembly to rotate, the knife rest assembly can stably rotate around the central axis of the knife rest assembly under the support of the support protrusions, preventing the knife rest assembly from shaking and ensuring that the knife rest assembly can stably crush the ingredients.

[0012] In the above-mentioned garlic press, the support protrusions include multiple support bumps arranged on the bottom surface. The support bumps protrude relative to the bottom surface, and the fitting mode between any support bump and the bottom wall is point contact. The point contact greatly reduces the contact area between the support protrusions and the bottom wall of the cup body, thereby reducing the friction between the knife rest assembly and the cup body, making it more labor-saving for the user to operate.

[0013] In the above-mentioned garlic press, the multiple support bumps are evenly arranged around the central axis of the knife rest assembly. When the knife rest assembly rotates, the bottom is evenly stressed, providing a good support effect for the knife rest assembly, avoiding the shaking of the knife rest assembly, and enhancing the user's hand feeling.

[0014] In the garlic masher, the support protrusion is arranged at the center of the knife holder assembly, and the projection of the central axis of the knife holder assembly on the horizontal plane is located within the projection of the support protrusion on the horizontal plane. While reducing the contact area between the bottom surface of the knife holder assembly and the bottom wall of the cup body, the knife holder assembly can be stably supported.

[0015] In the above-mentioned garlic masher, the height of the support protrusion is H, which satisfies 0.5mm≤H≤1mm. The height of the support protrusion is greater than 0.5mm, so that the height of the support protrusion is sufficient to support the knife holder assembly, avoid the bottom surface of the knife holder assembly from contacting the bottom wall of the cup body, and reduce the friction between the knife holder assembly and the cup body. The height of the support protrusion is less than 1mm, so that the support protrusion will not excessively lift the knife holder assembly, avoiding the knife holder assembly from occupying a large space.

[0016] In the above-mentioned garlic masher, the support protrusion is deformably arranged on the bottom surface of the knife holder assembly, and the support protrusion is deformed to press the top surface of the knife holder assembly against the upper cover. When the knife holder assembly is installed in the cup body, the knife holder assembly is clamped between the bottom wall of the cup body and the upper cover, and the support protrusion is slightly deformed. The compressed support protrusion pushes the knife holder assembly upward to press the top surface of the knife holder assembly against the upper cover, thereby preventing the knife holder assembly from shaking axially between the bottom wall of the cup body and the upper cover. The deformable characteristic of the support protrusion itself can compensate for the loss caused by the wear between the support protrusion and the bottom wall of the cup body, thereby solving the problem that the knife holder assembly becomes shorter due to long-term wear of the support protrusion, thereby loosening between the upper cover and the cup body, and ensuring that the knife holder assembly can stably cut the food through stable rotation when the garlic masher is working.

[0017] In the above-mentioned garlic masher, the upper cover includes a driving shaft and a bottom plate that abuts against the top surface of the knife holder assembly; the top of the knife holder assembly is provided with a mounting groove that matches the driving shaft, and the driving shaft is plugged into the mounting groove to stop the rotation of the mounting groove; wherein the mounting groove includes a mounting section and a guide section provided at the upper end of the mounting section, and the inner side wall of the guide section is inclined so that the inner diameter of the guide section gradually increases from bottom to top. When assembling the upper cover and the knife holder assembly, the driving shaft is inserted into the mounting section through the guide section, and the inner wall of the guide section that is inclined can guide the driving shaft for installation, and the plug-in can be achieved without the need for precise alignment of the driving shaft with the mounting groove, thereby reducing the difficulty of plug-in. At the same time, because the inner diameter of the guide section gradually increases from bottom to top, the top surface area of the knife holder assembly for abutting against the bottom plate is reduced, the friction between the knife holder assembly and the bottom plate is reduced, and the mutual wear between the knife holder assembly and the bottom plate is reduced, so that the rotation of the knife holder assembly is smoother and the user operation is more labor-saving.

[0018] In the above-mentioned garlic press, a rotating shaft is provided on the bottom wall, and a support groove is provided at the bottom of the knife rest assembly. The rotating shaft is inserted into the support groove and rotatably connected to the support groove. Among them, the depth of the support groove is A, satisfying A≤5mm. While facilitating the cleaning of the support groove, there is no need to set a relatively high rotating shaft to avoid as much as possible the problem of breakage at the connection between the rotating shaft and the cup body caused by the excessive height of the rotating shaft.

[0034] A garlic press proposed by the present utility model includes a cup body, an upper cover, and a knife rest assembly disposed inside the cup body. The upper cover covers the cup body, and the knife rest assembly is clamped between the upper cover and the bottom wall of the cup body. A support protrusion is provided on the bottom surface of the knife rest assembly, and the knife rest assembly abuts against the bottom wall through the support protrusion. Among them, the area of the support surface of the support protrusion for fitting the bottom wall is M1, and the area of the projection formed by the bottom surface of the knife rest assembly on the bottom wall is M2, and M1 < M2. By providing a support protrusion on the bottom surface of the knife rest assembly, when the knife rest assembly is installed in the cup body, the bottom surface of the knife rest assembly does not directly contact the bottom wall of the cup body, but abuts against the bottom wall of the cup body through the support protrusion. Because the area of the support surface of the support protrusion is smaller than the area of the bottom wall of the cup body, the support protrusion can reduce the contact area between the knife rest assembly and the bottom wall of the cup body. When the knife rest assembly rotates, the friction between the knife rest assembly and the cup body is reduced, so that it is more labor-saving for the user to pull the knife rest assembly to rotate, improving the user experience. At the same time, the reduction of the contact area between the knife rest assembly and the bottom wall of the cup body can also greatly reduce the wear between the knife rest assembly and the cup body, extending the service life of the garlic press.

[0040] Embodiment 1:

[0041] A garlic press, as Figures 1 to 6 shown, includes a cup body 200, an upper cover 100 and a knife rest assembly 300. The knife rest assembly 300 is disposed inside the cup body 200. A blade 340 for cutting food materials is provided on the knife rest assembly 300. The upper cover 100 is covered on the cup body 200 so that the knife rest assembly 300 is clamped between the upper cover 100 and the bottom wall 210 of the cup body 200 to limit the knife rest assembly 300 in the horizontal direction. That is, the central axis of the knife rest assembly 300 is vertically arranged, and the knife rest assembly 300 can only rotate around the central axis and will not displace in the horizontal direction. A supporting protrusion 310 protruding downward is provided on the bottom surface 315 of the knife rest assembly 300, and the knife rest assembly 300 abuts against the bottom wall 210 through the supporting protrusion 310. It is stipulated that the area of the supporting surface 311 of the supporting protrusion 310 for fitting the bottom wall 210 of the cup body 200 is M1, and the area of the region surrounded by the outer contour of the projection of the bottom surface 315 of the knife rest assembly 300 on the bottom wall 210 is M2, and M1 < M2, that is, the area of the supporting surface 311 of the supporting protrusion 310 is smaller than the area of the projection of the bottom surface 315 of the knife rest assembly 300 on the bottom wall 210.

[0042] The utility model sets a supporting protrusion 310 on the bottom surface 315 of the tool rest assembly 300. When the tool rest assembly 300 is installed in the cup body 200, the supporting protrusion 310 separates the bottom surface 315 of the tool rest assembly 300 from the bottom wall 210 of the cup body 200. The bottom surface 315 of the tool rest assembly 300 does not directly contact the bottom wall 210 of the cup body 200, but abuts against the bottom wall 210 of the cup body 200 through the supporting protrusion 310. Because the area of the supporting surface 311 of the supporting protrusion 310 is smaller than the area of the bottom wall 210 of the cup body 200, the supporting protrusion 310 can reduce the contact area between the tool rest assembly 300 and the bottom wall 210 of the cup body 200. When the tool rest assembly 300 rotates, the friction between the tool rest assembly 300 and the cup body 200 can be reduced, so that it is more labor-saving for the user to pull the tool rest assembly 300 to rotate, improving the user experience. At the same time, the reduction of the contact area between the tool rest assembly 300 and the bottom wall 210 of the cup body 200 can also greatly reduce the wear between the tool rest assembly 300 and the cup body 200, extending the service life of the garlic press.

[0043] As Figure 6 shown, the supporting protrusion 310 is an annular rib 312, and the central axis of the annular rib 312 coincides with the central axis of the tool rest assembly 300, so that the annular rib 312 stably supports the bottom surface 315 of the tool rest assembly 300. When the user pulls the tool rest assembly 300 to rotate, the tool rest assembly 300 can stably rotate around the central axis of the tool rest assembly 300 under the support of the supporting protrusion 310, preventing the tool rest assembly 300 from shaking and ensuring that the tool rest assembly 300 stably crushes ingredients such as garlic cloves. The fitting mode between the annular rib 312 and the bottom wall 210 is line contact, greatly reducing the contact area between the bottom of the annular rib 312 and the bottom wall 210 of the cup body 200 to minimize the influence of the friction between the annular rib 312 and the cup body 200 on the rotation of the tool rest assembly 300, making it more labor-saving for the user to pull the tool rest assembly 300 to rotate. Preferably, the surface of the annular rib 312 that fits with the bottom wall 210 is an arc surface protruding towards the bottom wall 210, that is, the longitudinal section of the annular rib 312 is semi-circular, which is convenient for processing and does not affect its stable support for the tool rest assembly 300.

[0044] As Figure 5As shown, the height of the supporting protrusion 310 is H, satisfying 0.5 mm ≤ H ≤ 1 mm. That is, the height of the supporting protrusion 310 is set within the range of 0.5 mm to 1 mm. The height of the supporting protrusion 310 is greater than 0.5 mm, so that the height of the supporting protrusion 310 is sufficient to support the tool rest assembly 300, avoiding the bottom surface 315 of the tool rest assembly 300 from contacting the bottom wall 210 of the cup body 200, and ensuring that the frictional force between the tool rest assembly 300 and the cup body 200 is maintained within a small range. The height of the supporting protrusion 310 is less than 1 mm, so that the supporting protrusion 310 does not excessively raise the tool rest assembly 300, avoiding the tool rest assembly 300 occupying a large space. The value of H can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm.

[0045] In this embodiment, the supporting protrusion 310 is made of a deformable material. The supporting protrusion 310 is deformably arranged on the bottom surface 315 of the tool rest assembly 300. When the tool rest assembly 300 is installed in the cup body 200, the tool rest assembly 300 is clamped between the bottom wall 210 of the cup body 200 and the upper cover 100, and the supporting protrusion 310 undergoes slight deformation. The compressed supporting protrusion 310 pushes the tool rest assembly 300 upward to press the top surface of the tool rest assembly 300 against the upper cover 100, avoiding axial shaking of the tool rest assembly 300 between the bottom wall 210 of the cup body 200 and the upper cover 100. Moreover, the deformable characteristic of the supporting protrusion 310 itself can compensate for the loss caused by wear between the supporting protrusion 310 and the bottom wall 210 of the cup body 200, solving the problem that the tool rest assembly 300 becomes shorter due to long-term wear of the supporting protrusion 310, resulting in looseness between the upper cover 100 and the cup body 200, and ensuring that the tool rest assembly 300 can stably cut food materials through stable rotation during the operation of the garlic press.

[0046] As Figure 5As shown, a rotating shaft 211 vertically protruding into the cup body 200 is provided on the bottom wall 210 of the cup body 200, and a support groove 320 is provided at the bottom of the tool rest assembly 300. When the tool rest assembly 300 is installed in place, the rotating shaft 211 is inserted into the support groove 320, and the central axis of the rotating shaft 211 coincides with the central axis of the support groove 320. Relative rotation can occur between the rotating shaft 211 and the support groove 320, so that the rotating shaft 211 is rotatably connected to the bottom of the tool rest assembly 300. During installation, the rotating shaft 211 can quickly install and position the tool rest assembly 300. When the tool rest assembly 300 rotates, the tool rest assembly 300 rotates around the rotating shaft 211, which can limit the tool rest assembly 300 in the horizontal direction, making the rotation of the tool rest assembly 300 more stable and reliable. With the height of the rotating shaft 211 unchanged, the setting of the support protrusion 310 can shorten the depth of the support groove 320, making the support groove 320 at the bottom of the tool rest assembly 300 easier to clean. Preferably, the depth of the support groove 320 is A, satisfying A ≤ 5 mm. While facilitating the cleaning of the support groove 320, there is no need to set a relatively high rotating shaft 211, so as to avoid the problem of fracture at the connection between the rotating shaft 211 and the cup body 200 caused by the excessive height of the rotating shaft 211 as much as possible.

[0047] It should be noted that in Figure 5 In the embodiment shown, the bottom surface 315 refers to the area of other regions on the bottom of the tool rest assembly 300 except the support groove 320, that is, the bottom surface 315 refers to the annular surface of the tool rest assembly 300 surrounding the support groove 320, and M2 is the area of the projection of this annular surface on the bottom wall 210. In an embodiment that does not include the support groove 320, that is, in an embodiment where the bottom of the tool rest assembly 300 is a plane, the bottom surface 315 also refers to the entire plane at the bottom of the tool rest assembly 300, and the projection of the support protrusion 310 on the bottom wall 210 is located within the projection of the bottom surface 315. In short, the bottom surface 315 refers to the surface of the tool rest assembly 300 that is used to contact the bottom wall 210 in the state without the support protrusion 310.

[0048] The upper cover 100 includes a bottom plate 110 and a drive shaft 120. The bottom plate 110 abuts against the top surface of the tool rest assembly 300. An installation groove 330 is provided at the top of the tool rest assembly 300. The bottom of the drive shaft 120 passes through the bottom plate 110 and is inserted into the installation groove 330. The drive shaft 120 is rotatably connected to the bottom plate 110, and the drive shaft 120 and the installation groove 330 are non-rotatably fitted to drive the tool rest assembly 300 to rotate. The non-rotatable fit between the drive shaft 120 and the installation groove 330 can be achieved by key connection, or by setting the drive shaft 120 as a special-shaped shaft, or by pin connection and other methods.

[0049] As Figure 2As shown in the figure, the installation groove 330 includes a connected installation section 331 and a guiding section 332. The guiding section 332 is provided at the upper end of the installation section 331. The inner side wall of the guiding section 332 is inclined obliquely upward, so that the inner diameter of the guiding section 332 gradually increases from bottom to top, presenting a horn shape with an upward opening. When assembling the upper cover 100 and the tool rest assembly 300, the driving shaft 120 is inserted into the installation section 331 through the guiding section 332. The inclined inner wall of the guiding section 332 can guide the installation of the end of the driving shaft 120, and the insertion can be achieved without the need for the driving shaft 120 to be precisely aligned with the installation groove 330, reducing the insertion difficulty. At the same time, because the inner diameter of the guiding section 332 gradually increases from bottom to top, the top surface area of the tool rest assembly 300 for abutting against the bottom plate 110 is reduced, the friction between the tool rest assembly 300 and the bottom plate 110 is reduced, the mutual wear between the tool rest assembly 300 and the bottom plate 110 is reduced, making the rotation of the tool rest assembly 300 smoother and the user operation more labor-saving.

[0050] Embodiment Two:

[0051] As Figure 7 shown in the figure, the difference between this embodiment and Embodiment One is that in this embodiment, the supporting protrusion is two arc-shaped ribs 313. The setting of the two arc-shaped ribs 313 can further reduce the contact area between the supporting protrusion and the cup body on the basis of Embodiment One, reduce the influence of the friction between the tool rest assembly 300 and the cup body on the rotation of the tool rest assembly 300, and make the user operation more labor-saving. The two arc-shaped ribs 313 are symmetrically arranged left and right along the central plane of the tool rest assembly 300 (i.e., the plane coinciding with the central axis of the tool rest assembly 300), so that the supporting protrusion supports the bottom surface 315 of the tool rest assembly 300 more stably, preventing the tool rest assembly 300 from shaking during rotation.

[0052] Embodiment Three:

[0053] As Figure 8 shown in the figure, the difference between this embodiment and Embodiment One is that in this embodiment, the supporting protrusion includes a plurality of supporting bumps 314. The plurality of supporting bumps 314 are provided on the bottom surface 315 of the tool rest assembly 300 and protrude downward relative to the bottom surface 315. Each supporting bump 314 is in point contact with the bottom wall. The point contact greatly reduces the contact area between the supporting protrusion and the bottom wall of the cup body, thereby reducing the friction between the tool rest assembly 300 and the cup body, and making the user operation more labor-saving. The plurality of supporting bumps 314 are evenly arranged around the central axis of the tool rest assembly 300, so that when the tool rest assembly 300 rotates, the bottom is evenly stressed, the supporting effect on the tool rest assembly 300 is good, the tool rest assembly 300 is prevented from shaking, and the user feel is improved.

[0054] Embodiment Four:

[0055] As Figure 9As shown in the figure, the difference between this embodiment and the first embodiment is that in this embodiment, the support protrusion 310 is provided at the central position of the tool rest assembly 300. The projection of the central axis of the tool rest assembly 300 on the horizontal plane is located within the projection of the support protrusion 310 on the horizontal plane, and the central axis of the tool rest assembly 300 passes through the center of the support protrusion 310. While reducing the contact area between the bottom surface 315 of the tool rest assembly 300 and the bottom wall of the cup body, the tool rest assembly 300 can be stably supported.

[0056] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
