Description

Technical Field

[0001] This utility model belongs to the technical field of food processor blade structure, specifically relating to a food processor blade assembly. Background Technology

[0002] A food processor is a household appliance that integrates functions such as blending, mixing, and crushing. It is usually composed of a main unit base, a cup body, a blade assembly, and a control system. In actual use, different blades are selected according to different functions. The food to be processed is added to the cup body, and the main unit base drives the blade assembly to rotate to blend, mix, or crush the food to be processed in the cup body.

[0003] As is well known, the blade assembly of most food processors is usually mounted under the cup body and sealed with a sealing ring. However, since the shaft of the blade assembly rotates continuously during actual use, and the shaft and the sealing ring are in a dynamic sealing state, leakage is likely to occur at the connection between the shaft and the sealing ring during use. When this happens, the leaked liquid inside the food processor will drip down the shaft into the base of the main unit, which will not only cause corrosion of the shaft, but also short circuit damage to various components inside the base of the main unit.

[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a food processor blade assembly.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a food processor blade assembly that ensures the sealing of the blade assembly and improves the stability of the food processor.

[0007] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0008] A food processor blade assembly includes: a rotating shaft, an assembly linkage mechanism, and a compression-type sealing protection mechanism.

[0009] The assembly linkage mechanism is mounted on both ends of the rotating shaft. The assembly linkage mechanism includes a cutter head, a fixing nut, and a linkage end. The cutter head is sleeved on the outside of the rotating shaft, and the fixing nut and linkage end are respectively fixedly mounted on both ends of the rotating shaft.

[0010] The compression-type sealing protection mechanism is assembled on the outside of the rotating shaft. The compression-type sealing protection mechanism includes an assembly limiting post, a waterproof fixing block, a fixed sealing ring, a dynamic sealing ring, a compression component, and a moisture-proof early warning component. The assembly limiting post is sleeved on the outside of the rotating shaft. The waterproof fixing block is sleeved on the outside of the rotating shaft and threadedly connected to one end of the assembly limiting post. The fixed sealing ring is arranged below the waterproof fixing block. The compression component is arranged between the waterproof fixing block and the assembly limiting post for continuously compressing the waterproof fixing block. The moisture-proof early warning component is fixedly assembled on the assembly limiting post and moves away from the waterproof fixing block to provide a moisture-proof early warning.

[0011] In one or more embodiments of this utility model, both ends of the rotating shaft are provided with external threads. This facilitates the connection and fixation of the fixing nut and the linkage end through the engagement of the internal and external threads. A limiting ring is fixedly sleeved on the outer side of the rotating shaft, and the cutting head is assembled between the fixing nut and the limiting ring. The fixing nut is assembled and fixed by the mutual compression between the limiting ring and the fixing nut.

[0012] In one or more embodiments of this utility model, the linkage end includes two parts: a drive end body and a positioning post. The drive end body and one end of the rotating shaft form a threaded pair. It can be connected to the main unit base through the drive end body.

[0013] In one or more embodiments of this utility model, an assembly groove is provided on the side of the drive end body opposite to the rotating shaft, and the positioning post is fixedly assembled in the assembly groove. The central axis of the positioning post is on the same straight line as the central axis of the rotating shaft. The positioning post is used to limit the assembly during the connection process between the linkage end and the main unit base.

[0014] In one or more embodiments of this utility model, the waterproof fixing block has a trapezoidal cross-section, and a stepped assembly through hole is formed inside the waterproof fixing block. The stepped assembly through hole allows for assembly and positioning of the assembly limiting post, dynamic sealing ring, and extrusion component. An internal thread is formed on the inner wall of the stepped assembly through hole, and one end of the waterproof fixing block is threadedly connected to the assembly limiting post. The assembly limiting post and the waterproof fixing block are connected and fixed through threaded engagement.

[0015] In one or more embodiments of this utility model, the extrusion component includes a bearing, a pair of extrusion plates, and several support springs. The bearing is sleeved on the outside of the rotating shaft. The bearing serves to limit and fix the rotation of the rotating shaft. The pair of extrusion plates are disposed between the dynamic seal ring and the assembly limiting post. The pair of extrusion plates support and limit the dynamic seal ring and the bearing.

[0016] In one or more embodiments of this utility model, multiple evenly distributed anti-drop elements are integrally formed on the adjacent sides of the pair of extrusion plates. A plurality of support springs are arranged between the pair of extrusion plates, and each support spring is sleeved on the outside of the anti-drop elements. The anti-drop elements serve to prevent and limit the release of the support springs. The resetting of the support springs continuously compresses the pair of extrusion plates, thereby ensuring that the extrusion plates continuously compress and limit the dynamic sealing ring, guaranteeing the stability of the dynamic sealing ring's sealing protection of the rotating shaft.

[0017] In one or more embodiments of this utility model, the moisture-proof warning component includes a storage ring and a drying filler. The storage ring is threaded onto the end of the assembly limiting post located outside the waterproof fixing block. The storage ring serves to store the drying filler. An auxiliary sealing ring is fitted between the storage ring and the rotating shaft. The drying filler is filled inside the storage ring. The drying filler can provide moisture protection and absorb moisture for the assembly limiting post and the rotating shaft, reducing the likelihood of corrosion of the rotating shaft due to humid environments during use.

[0018] In one or more embodiments of this utility model, the storage ring includes a ring body, a mesh inner side plate, and an observation plate. The outer side of the ring body has external threads, and the end of the assembly limiting post away from the waterproof fixing block has a threaded assembly groove that matches the ring body. The ring body and the assembly limiting post are connected and fixed by a threaded connection.

[0019] In one or more embodiments of this utility model, the mesh inner side plate is arranged on the side of the ring body close to the rotating shaft. This allows the ring body to communicate with the outside air through the conductive effect of the mesh inner side plate, thereby facilitating the dehumidification of the air between the storage ring and the rotating shaft by the dry filler. The observation plate is fixedly connected to one end of the ring body outside the threaded assembly groove. The moisture absorption state of the dry filler can be observed and judged through the observation plate.

[0020] Compared with the prior art, the food processor blade assembly disclosed in this utility model improves the sealing effect of the blade assembly through the corresponding structural design, reduces the risk of sealing leakage during use, and improves the reliability of the food processor blade assembly.

Detailed Implementation

[0030] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0031] like Figures 1 to 5 As shown, the food processor blade assembly in one embodiment of this utility model includes: a rotating shaft 1, an assembly linkage mechanism 2, and a compression-type sealing protection mechanism 3. In practical applications, different blade heads 201 can be fixedly assembled on the outside of the rotating shaft 1 via the assembly linkage mechanism 2. The blade heads 201 can be rotated by driving the rotating shaft 1 to achieve mixing, stirring, or pulverizing functions. Simultaneously, the compression-type sealing protection mechanism 3 can seal and protect the rotating shaft 1.

[0032] like Figure 1 As shown, the assembly linkage mechanism 2 is mounted on both ends of the rotating shaft 1. The assembly linkage mechanism 2 includes a cutter head 201, a fixing nut 202, and a linkage end 203. The cutter head 201 is sleeved on the outside of the rotating shaft 1. The food in the cup is processed by the cutter head 201 rotating with the rotating shaft 1. The fixing nut 202 and the linkage end 203 are respectively fixedly mounted on both ends of the rotating shaft 1. The fixing nut 202 can be used to assemble and fix the cutter head 201, and the linkage end 203 can be used to drive the rotating shaft 1 in a linkage manner.

[0033] like Figure 1 As shown, both ends of the rotating shaft 1 are provided with external threads. This facilitates the connection and fixation of the fixing nut 202 and the linkage end 203 through the engagement of the internal and external threads.

[0034] like Figures 1 to 2 A limiting ring 204 is fixedly sleeved on the outer side of the rotating shaft 1, and the cutter head 201 is assembled between the fixing nut 202 and the limiting ring 204. The fixing nut 202 is assembled and fixed by the mutual compression between the limiting ring 204 and the fixing nut 202.

[0035] like Figure 1 As shown, the linkage end 203 includes two parts: a drive end body 2031 and a positioning post 2032. The drive end body 2031 and one end of the rotating shaft 1 form a threaded pair. It can be connected to the main unit base through the drive end body 2031.

[0036] like Figure 1 As shown, the drive end body 2031 has an assembly groove on the side opposite to the rotating shaft 1. The positioning post 2032 is fixedly assembled in the assembly groove, and the central axis of the positioning post 2032 is on the same straight line as the central axis of the rotating shaft 1. The positioning post 2032 is used to limit the assembly during the connection process between the linkage end 203 and the main unit base.

[0037] like Figure 1 As shown, the compression-type sealing protection mechanism 3 is assembled on the outside of the rotating shaft 1. The compression-type sealing protection mechanism 3 includes an assembly limiting post 301, a waterproof fixing block 302, a fixed sealing ring 303, a dynamic sealing ring 304, a compression component, and a moisture-proof warning component. The assembly limiting post 301 is sleeved on the outside of the rotating shaft 1. The rotating shaft 1 is assembled and limited by the cooperation between the assembly limiting post 301 and the waterproof fixing block 302.

[0038] like Figures 1 to 2As shown, the waterproof fixing block 302 is sleeved on the outside of the rotating shaft 1 and threadedly connected to one end of the assembly limiting post 301. The assembly limiting post 301 is assembled and fixed by the waterproof fixing block 302. At the same time, the assembly limiting post 301 and the bottom surface of the cup body are sealed and limited by the pressure of the fixed sealing ring 303 by the waterproof fixing block 302. The fixed sealing ring 303 is arranged below the waterproof fixing block 302.

[0039] Specifically, the waterproof fixing block 302 has a trapezoidal cross-section and a stepped assembly through hole. This stepped assembly through hole allows for the assembly limiting post 301, the dynamic sealing ring 304, and the extrusion component to be assembled and positioned. An internal thread is provided on the inner wall of the stepped assembly through hole, and the waterproof fixing block 302 is threadedly connected to one end of the assembly limiting post 301. The assembly limiting post 301 and the waterproof fixing block 302 are connected and fixed through this threaded engagement.

[0040] like Figures 1 to 2 As shown, the extrusion component is positioned between the waterproof fixing block 302 and the assembly limiting post 301, and is used to continuously extrude force onto the waterproof fixing block 302. The extrusion component includes a bearing 305, a pair of extrusion plates 306, and several support springs 307. The bearing 305 is sleeved on the outer side of the rotating shaft 1. The bearing 305 serves to limit and fix the rotation of the rotating shaft 1.

[0041] like Figures 1 to 2 As shown, a pair of extrusion plates 306 are disposed between the dynamic seal ring 304 and the assembly limiting post 301. The pair of extrusion plates 306 support and limit the dynamic seal ring 304 and the bearing 305.

[0042] like Figures 1 to 2 As shown, multiple evenly distributed anti-drop features are integrally formed on the adjacent sides of a pair of extrusion plates 306. Several support springs 307 are arranged between the pair of extrusion plates 306, and all support springs 307 are sleeved on the outside of the anti-drop features. The anti-drop features act as anti-detachment and limiting mechanisms for the support springs 307. The resetting of the support springs 307 continuously compresses the pair of extrusion plates 306, thereby ensuring that the extrusion plates 306 continuously compress and limit the dynamic sealing ring 304, guaranteeing the stability of the dynamic sealing ring 304 in sealing and protecting the rotating shaft 1.

[0043] like Figures 1 to 3 As shown, the moisture-proof warning component is fixedly mounted on the assembly limiting post 301, moving away from the waterproof fixing block 302, for issuing moisture-proof warnings. The moisture-proof warning component includes a storage ring 308 and a dry filler 309. The storage ring 308 is threadedly mounted on the end of the assembly limiting post 301 located outside the waterproof fixing block 302. The storage ring 308 serves to store the dry filler 309.

[0044] In addition, an auxiliary sealing ring is installed between the storage ring 308 and the rotating shaft 1. A drying filler 309 is filled inside the storage ring 308. The drying filler 309 can prevent moisture absorption and reduce the risk of corrosion of the rotating shaft 1 due to humid environments during use.

[0045] Preferably, the dry filler 309 can be made of anhydrous copper sulfate particles. Anhydrous copper sulfate particles change from white to blue after absorbing water, and the sealing effect of the dynamic sealing ring 304 can be observed and judged by observing the color change of the receiving ring 308.

[0046] like Figures 1 to 3 As shown, the storage ring 308 includes a ring body 3081, a mesh inner side plate 3082, and an observation plate 3083. The outer side of the ring body 3081 has external threads, and the end of the mounting limiting post 301 away from the waterproof fixing block 302 has a threaded mounting groove that matches the ring body 3081. The ring body 3081 and the mounting limiting post 301 are connected and fixed by a threaded connection.

[0047] like Figures 1 to 3 As shown, the mesh inner side plate 3082 is arranged on the side of the ring 3081 close to the rotating shaft 1. This allows the ring 3081 to communicate with the outside air through the conduction of the mesh inner side plate 3082, thus facilitating the dehumidification of the air between the storage ring 308 and the rotating shaft 1 by the drying filler 309. The observation plate 3083 is fixedly connected to one end of the ring 3081 outside the threaded assembly groove. The moisture absorption state of the drying filler 309 can be observed and judged through the observation plate 3083.

[0048] Specifically, the observation plate 3083 is made of transparent acrylic sheet.

[0049] like Figure 6 As shown, in practical applications, different cooking functions can be achieved by changing different types of blades 201. The types of blades 201 include: dough kneading blade, stirring blade, stir-frying blade, and milk foaming blade.

[0050] In practical use, during assembly, the rotating shaft 1 is inserted through the cup body, and the waterproof fixing block 302 is fitted onto the outside of the rotating shaft 1. Then, from top to bottom, the dynamic sealing ring 304, the extrusion plate 306, the support spring 307, the bearing 305, and the assembly limiting post 301 are sequentially assembled into the stepped assembly through hole. The assembly limiting post 301 is assembled and fixed by means of a threaded connection between the waterproof fixing block 302 and the assembly limiting post 301.

[0051] During assembly, the waterproof fixing block 302 and the cup body are sealed and protected by pressing against the bottom surface of the cup body to form a fixed sealing ring 303. Simultaneously, during the threaded connection between the limiting post 301 and the waterproof fixing block 302, the bearing 305 presses against a pair of pressing plates 306. The combination of the pressing plates 306, several support springs 307, and the waterproof fixing block 302 continuously presses against the dynamic sealing ring 304. This continuous pressing ensures the sealing effect of the dynamic sealing ring 304.

[0052] Additionally, the space between the storage ring 308 and the rotating shaft 1 can be dehumidified using the drying filler 309. During the moisture absorption process, the drying filler 309 will change color. The presence of liquid leakage on the outside of the rotating shaft 1 can be determined by observing the color change of the drying filler 309 through the mesh inner side plate 3082. This facilitates timely replacement of the dynamic sealing ring 304, reducing the risk of damage to the main unit base due to continuous leakage.

[0053] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of this disclosure is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this disclosure. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0054] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
