Description

Technical Field

[0001] The utility model relates to the field of food processors, and particularly relates to a food processor with reliable sealing. Background Art

[0002] At present, conventional wall breakers usually adopt a touch or button control method for function selection and control. Their sealing and installation and fixation are already very mature. However, when using a knob accessory for operation, the sealing problem between the knob and the main body needs to be solved.

[0003] In the prior art, a patent CN208491856U discloses a food processor. A knob is installed on its base, and the knob is rotatably connected to the base. The knob can rotate integrally. Based on the design of this knob, its waterproof structure is a groove provided at the edge of the knob and a surrounding edge provided at the edge of the base. Waterproofing is achieved through the clearance fit between the surrounding edge and the inner wall surface of the groove. This waterproof structure of this solution makes the structure of the knob and the base relatively complex and the cost is high. If a sealing ring is arranged between the knob and the base to achieve sealing and waterproofing, although it is beneficial to reduce the cost, when the knob rotates, it will have sliding friction with the sealing ring, which will cause the knob to be laborious to operate, and after a long time, the sealing ring is prone to deformation and failure, resulting in sealing failure. For these reasons, the solution using a sealing ring is not adopted in the prior art.

[0004] In addition, in the above solution, the operation panel is inclined. If there is liquid flowing down when the operation panel is above the knob, the liquid is likely to flow into the above-mentioned groove, reducing the waterproof reliability. If an internal drainage structure is not provided, it will cause the internal structure of the knob to rust, which is not conducive to extending the service life of the accessory, and adding a drainage structure will cause the structure to be complicated.

[0005] Therefore, how to achieve the waterproofing of the knob configuration on the premise of simplifying the structure remains to be solved. Summary of the Utility Model

[0047] Such as Figures 1 to 8As shown in the figure, the present application provides a food processor with reliable sealing, which includes a main body 10 and a cup assembly installed on the main body 10. The main body 10 is provided with a knob 11, and the main body 10 is provided with an operation panel 12 protruding from the installation position of the cup assembly. The operation panel 12 is provided with an installation area. The knob 11 includes a cylindrical rotating housing 13 and an installation part 14 arranged inside the rotating housing 13. The installation part 14 is fixedly connected to the installation area. The rotating housing 13 is rotatable relative to the main body 10, and a sealing ring 15 is arranged between the installation part 14 and the installation area.

[0048] Different from the prior art, the knob 11 of the present application is not installed by integral rotation. The installation part 14 is fixedly connected to the main body 10 and does not rotate. Then, by arranging the sealing ring 15 between the installation part 14 and the installation area, when the user operates the knob 11, only the rotating housing 13 rotates, and the external force is not transmitted to the sealing ring 15, which has no impact on the sealing ring 15. In this way, reliable sealing can be ensured. Compared with the prior art that uses a groove on the knob 11 and a surrounding edge on the base to achieve waterproofing through the cooperation of the surrounding edge and the groove, the use of the sealing ring 15 for sealing in the present application is beneficial to simplify the structures of the knob 11 and the main body 10.

[0049] As Figure 1 shown in the figure, the main body 10 can be a thinner base type or a seat type with a certain axial height. The common operation panel 12 can be set horizontally, vertically or obliquely, which is not limited in the present application. The installation area is provided with structures such as grooves or bosses that cooperate with the knob 11. The operation panel 12 also has other key areas, indication areas, etc. outside the installation area. For example, the main body 10 can achieve different control functions through the knob 11 in the installation area and the keys in the key area, or the user can choose different operation methods according to their preferences. Or when the user operates the knob 11 for function control, feedback is obtained through the lighting display in the indication area to improve the user experience.

[0050] As a preferred implementation manner, the installation area is provided with a concave installation groove 16. The lower end of the installation part 14 extends into the installation groove 16. The sealing ring 15 is clamped between the installation groove 16 and the installation part 14. The rotating housing 13 covers the upper part of the installation groove 16 and has a clearance fit with the operation panel 12.

[0051] As Figure 2 or Figure 3 shown in the figure, by setting the concave installation groove 16, the knob 11 can be partially sunk, which is beneficial to reducing the height of the knob 11 and increasing the aesthetic appearance of the machine; the clamping setting of the sealing ring 15 can improve the installation reliability and enhance the sealing effect; the clearance fit between the rotating housing 13 and the operation panel 12 ensures that the user is not interfered when rotating the rotating housing 13 and can improve the smoothness of operation.

[0052] As Figure 4As shown, the lower end of the installation part 14 extends into the installation groove 16, the upper end of the installation part 14 protrudes upward, the rotating housing 13 is supported on the upper end of the installation part 14, and the circumferential bottom edge of the rotating housing 13 is slightly higher than the operation panel 12 to prevent friction between the rotating housing 13 and the operation panel 12 when the rotating housing 13 rotates.

[0053] As a preferred embodiment of this embodiment, the installation groove 16 includes a groove bottom wall and a groove peripheral wall surrounding the groove bottom wall. The upper end of the sealing ring 15 is provided with an outwardly extending flanging 151 in the radial direction, and the lower end of the sealing ring 15 is provided with an inwardly extending flanging 152 in the radial direction. The flanging 151 abuts against the top of the groove peripheral wall, and the flanging 152 fits against the groove bottom wall and is pressed by the installation part 14.

[0054] As Figure 5 shown, by optimizing the shape of the sealing ring 15, the outwardly extending flanging 151 and the inwardly extending flanging 152 can form a double axial limit, which can prevent the sealing ring 15 from slipping and affecting the sealing effect. The inwardly extending flanging 152 can also prevent the water flowing into the space between the sealing ring 15 and the installation part 14 from flowing downward, which can enhance the waterproof effect.

[0055] Different from the above installation groove 16, in another embodiment, the installation area is provided with a convex platform protruding upward, and the installation part 14 is sleeved and fixed with the convex platform, which can enhance the supporting effect of the knob 11.

[0056] As a preferred embodiment, the inner peripheral wall of the sealing ring 15 is provided with multiple circles of sealing ribs 153 arranged at intervals in the axial direction, and the sealing ribs 153 abut against the outer peripheral wall of the installation part 14. As Figure 5 or Figure 8 shown, by providing multiple circles of sealing ribs 153 distributed axially, the sealing ring 15 can be tightly attached to the installation part 14 and the sealing ring 15 can be prevented from slipping, which can improve the reliability of the seal.

[0057] When the installation area is provided with the installation groove 16, as a preferred embodiment, the groove bottom wall of the installation groove 16 is provided with a positioning hole 161, and the bottom of the installation part 14 is provided with a positioning post 141 that is inserted and matched with the positioning hole 161.

[0058] As Figure 3 and Figure 7 shown, the pre - fixation of the knob 11 can be realized by the insertion and matching of the positioning post 141 and the positioning hole 161, which can prevent the knob 11 from being displaced when it is further fixed, ensure the accurate installation position of the knob 11, and is beneficial to improving the installation efficiency.

[0059] Specifically, when installing the knob 11, first insert the positioning post 141 into the positioning hole 161 to realize the radial limit of the installation part 14, and then when performing the axial limit on the installation part 14, the installation part 14 can be prevented from being displaced and affecting the installation accuracy. The installation part 14 can be axially limited by locking screws, etc. For example, asFigure 3 , Figure 5 and Figure 7 As shown in Figure 7 , a first mounting hole 162 is provided on the bottom wall of the mounting groove 16, and a second mounting hole 142 is provided at the bottom of the mounting portion 14. The mounting portion 14 can be fixed by passing a fastener 17 through the first mounting hole 162 and the second mounting hole 142. Using a screw to lock can ensure that the mounting portion 14 is firmly fixed. The higher the stability of the mounting portion 14, the smoother and easier it is for the user to rotate the rotating housing 13, preventing the mounting portion 14 from loosening and affecting the operating feel of the rotating housing 13.

[0060] It can be understood that the mounting portion 14 and the mounting groove 16 can also be directly fixed by the fastener 17, omitting the pre-positioning process, so as to simplify the mounting structure and process.

[0061] Preferably, there are at least three positioning posts 141, and the mounting portion 14 and the mounting groove 16 are fixed by at least one fastener 17. The radial movement of the mounting portion 14 can be limited by the insertion and cooperation of at least three positioning posts 141 and the positioning holes 161, and the axial limit of the mounting portion 14 can be achieved by using at least one fastener 17 to fix. On the premise of meeting the fixing requirements, it is beneficial to reduce the use of accessories.

[0062] As Figure 3 and Figure 7 shown, the three positioning posts 141 are distributed in a triangular shape, and the three positioning holes 161 are arranged in one-to-one correspondence with the three positioning posts 141. When the positioning posts 141 are inserted into the positioning holes 161, the mounting portion 14 is stable in the radial and circumferential directions, ensuring the accurate mounting position of the mounting portion 14. Although three first mounting holes 162 and second mounting holes 142 are shown in the figure, only one fastener 17 can be used for fixing. Of course, in order to enhance the fixing effect, two or three fasteners 17 can also be used in combination. As Figure 3 shown, the three positioning holes 161 and the three first mounting holes 162 are arranged alternately, which can make full use of the space and improve the uniformity of the limit fixing.

[0063] As a preferred embodiment, the operation panel 12 is horizontally arranged, and the knob 11 is vertically arranged with respect to the operation panel 12. By arranging the operation panel 12 horizontally, it is beneficial to prevent the water on the operation panel 12 from flowing towards the knob 11, providing favorable conditions for waterproofing the knob 11.

[0064] Of course, in other embodiments, the operation panel 12 can also be arranged at a certain inclination angle to thin the base.

[0065] When the installation area is provided with an installation groove 16, as a preferred embodiment, the host 10 includes a main body 101 and a cover plate 102. The installation groove 16 is arranged on the main body 101, and the cover plate 102 is provided with an avoidance opening 1021 corresponding to the installation groove 16. The top surface of the cover plate 102 is not lower than the top surface of the outward-turned edge 151.

[0066] As Figure 2 and Figure 4 As shown, the cover plate 102 not only plays a protective role but also a decorative role. The fact that the top surface of the cover plate 102 is not lower than the top surface of the outward-turned edge 151 can prevent partial exposure of the outward-turned edge 151 and affect the aesthetics. Preferably, the top surface of the cover plate 102 is flush with the top surface of the outward-turned edge 151 to prevent water accumulation at the position of the outward-turned edge 151. Among them, when the host 10 includes the main body 101 and the cover plate 102, the platform parts of the main body 101 and the cover plate 102 both belong to the operation panel 12, that is, the operation panel 12 can be a single-layer structure or a double-layer structure.

[0067] As a preferred implementation manner, the inner peripheral wall of the rotating housing 13 is provided with a stepped portion 131 extending radially inward. The stepped portion 131 is rotatably connected to the installation portion 14. The top of the rotating housing 13 is provided with an opening, and the knob 11 further includes a decorative cover 132 for closing the opening.

[0068] As Figure 4 and Figure 6 As shown, the setting of the stepped portion 131 not only provides conditions for the rotational installation of the rotating housing 13 but also can strengthen the structural strength of the rotating housing 13, prevent the rotating housing 13 from cracking, twisting and deforming, etc., and is beneficial to extending its service life; the decorative cover 132 can play roles such as decoration, dust prevention, and waterproofing.

[0069] As Figure 4 As shown, the stepped portion 131 extends radially inward from the inner peripheral wall of the rotating housing 13 to form a support structure. The stepped portion 131 can be a multi-step design to avoid the structure of the installation portion 14. At the same time, the stepped portion 131 and the installation portion 14 can be rotationally connected through shaft and hole cooperation. The specific structure can refer to the prior art and will not be elaborated here.

[0070] The technical solutions protected by the present utility model are not limited to the above embodiments. It should be noted that the combination of the technical solution of any one embodiment with the technical solutions of one or more other embodiments is within the protection scope of the present utility model. Although the present utility model has been described in detail with general descriptions and specific embodiments above, on the basis of the present utility model, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present utility model all belong to the scope required to be protected by the present utility model.
