Description

Technical Field

[0001] The present application relates to the technical field of small household appliances, and in particular to a blender cup assembly and a food processor. Background Art

[0002] The food processor comprises a driving device and a mixing cup assembly. The mixing cup assembly comprises a mixing cup and a mixing blade. The driving device drives the mixing blade assembly to rotate in the mixing cup, thereby processing the food in the mixing cup.

[0003] For easy cleaning, the mixing blade is connected to the shaft sleeve, and the shaft sleeve is detachably connected to the shaft at the bottom of the mixing cup. When cleaning is required, the consumer can grab the shaft sleeve and take the mixing blade out of the mixing cup. In order to prevent the shaft sleeve from moving (that is, the mixing blade from moving), the shaft sleeve is generally short. Therefore, when the consumer grabs the shaft sleeve to take out the mixing blade, the hand is likely to touch the mixing blade and get injured. Utility Model Content

[0004] The purpose of the present application is to disclose a mixing cup assembly and a food processor. When taking out the mixing knife from the mixing cup assembly, the hand is not likely to touch the mixing knife and will not get hurt.

[0005] In the first aspect, the present application discloses a blending cup assembly. The blending cup assembly comprises a blending cup, a blending blade and a cup cover assembly; a fixed shaft is provided at the bottom of the blending cup; the cup cover assembly is engaged with the blending cup, and comprises a cover body and a blade removal device, and the blade removal device comprises a motion rod, a magnetic member and a driving mechanism, wherein: wherein: the magnetic member is located at the end of the motion rod away from the cover body; when the motion rod is subjected to a first action force applied by the driving mechanism, the magnetic member moves in a direction away from the cover body to a blade removal position, so that the magnetic member absorbs the blending blade.

[0006] As configured above, during the process of taking out the stirring blade, the stirring blade is magnetically attracted by the magnetic part and is located at the end of the movement rod relative to the cover body. The consumer's hand is far away from the stirring blade and will not touch the stirring blade, thus avoiding injury.

[0007] In some embodiments, when the motion rod is subjected to the second force applied by the driving mechanism, the magnetic member moves toward the cover body to a knife-off position. In the knife-off position, the magnetic member is disengaged from the stirring knife, and the stirring knife is assembled with the fixed shaft.

[0008] As set up above, the magnetic part moves toward the cover body to the disengaging position, corresponding to the cup cover assembly covering the stirring cup. In this case, the magnetic part is separated from the stirring blade by the second force. Because the cup cover assembly covers the stirring cup and can block the stirring blade, the separated stirring blade will not hurt your hand.

[0009] In some embodiments, the knife-removing device further comprises an outer rod assembled on the cover body, the movement rod is inserted into the outer rod, and a locking structure is provided between the outer rod and the movement rod; the movement rod is locked in the knife-removing position by the locking structure. The driving mechanism comprises a second driving mechanism; the second driving mechanism is provided on the cover body, applies the second force to unlock the locking structure, and the second driving mechanism also drives the magnetic member to the knife-removing position.

[0010] As set up above, by setting a locking structure between the moving rod and the outer rod, the second driving mechanism applies a second force to unlock the locking structure and drive the magnetic part to the knife disengaging position. In this way, the structure of the cup cover assembly is simple and the stirring knife is easy to disengage from the magnetic part.

[0011] In some embodiments, the knife removing device also includes an outer rod assembled on the cover body, the moving rod is inserted into the outer rod, and a locking structure is arranged between the outer rod and the moving rod; the driving mechanism includes a first driving mechanism; the first driving mechanism applies the first force to make the moving rod move in a vertical direction relative to the outer rod until it is locked by the locking structure to maintain it in the knife removing position.

[0012] As described above, by providing a locking structure between the moving rod and the outer rod, the moving rod is moved relative to the outer rod by a first force until the moving rod is locked by the locking structure, so that the magnetic part can be maintained in the knife removal position, making it easier to attract the stirring knife. Moreover, after the stirring knife is attracted, the moving rod is locked to ensure the distance between the magnetic part and the stirring knife, thereby ensuring the magnetic force, and the stirring knife is not easy to fall off. In addition, since the driving mechanism includes a first driving mechanism and a second driving mechanism, the first driving mechanism applies the first force. The second driving mechanism is arranged on the cover body to apply the second force, so that the first driving mechanism and the second driving mechanism are independent of each other, which is conducive to the layout of the first driving mechanism and the second driving mechanism.

[0013] In some embodiments, the knife removing device further comprises a first elastic member, which is in contact with the outer rod and the magnetic member; when the magnetic member moves away from the cover body to the knife removing position, the first elastic member is compressed.

[0014] As set up above, since the first elastic member is compressed when the moving rod reaches the knife removing position, correspondingly, during the movement toward the cover body, the first elastic member gradually returns to its natural state, and the elastic force generated by the restoration of the natural state unlocks the locking structure, thereby facilitating the movement of the magnetic member to the knife removing position.

[0015] In some embodiments, the first driving mechanism includes a button and a second elastic member, the movement rod abuts against the button; and opposite ends of the second elastic member abut against the button and the cover body, respectively.

[0016] As configured above, the first driving mechanism includes a button and a second elastic member, which facilitates driving the moving rod so that the moving rod drives the magnetic member to move to the knife taking position; it is also beneficial to reset the button and drive the magnetic member to move to the knife disengaging position.

[0017] In some embodiments, the motion rod is provided with a clamping column, and the second driving mechanism includes a locking rod, a first reset member, a second reset member, and a push rod, wherein the first reset member is connected to the locking rod and the cover body, and the second reset member is in contact with the push rod and the cover body. The locking rod is subjected to an external force and rotates in a first direction in a horizontal plane, the first reset member is deformed, the locking rod pushes the push rod to extend and compresses the second reset member, and the push rod cooperates with the clamping column through an inclined surface to apply the second force; when the locking rod is not subjected to an external force, the first reset member returns to a natural state, and the push rod retracts under the action of the second reset member.

[0018] As described above, the moving rod is provided with a clamping column, and the second driving mechanism includes a locking rod, a first reset member, a second reset member and a push rod. Through the cooperation between them, the operation of taking out the mixing knife can be performed only when the second driving mechanism is not subject to force, ensuring that the consumer's hand will not touch the mixing knife to avoid injury.

[0019] In some embodiments, the motion rod is provided with a clamping column, and the second driving mechanism includes a push rod and a reset member, and the reset member abuts against the push rod and the cover body. The push rod is subjected to an external force and moves linearly in a first direction until the push rod and the clamping column cooperate through an inclined surface to apply the second force; when the push rod is not subjected to an external force, the reset member returns to a natural state so that the push rod moves linearly in a second direction opposite to the first direction, and the push rod retracts.

[0020] As set up above, since the second driving mechanism includes a push rod and a reset member, the knife removal is achieved through the cooperation between the reset member and the push rod. The operation of removing the mixing knife can only be performed when the second driving mechanism is not subject to force, ensuring that the consumer's hand will not touch the mixing knife to avoid injury.

[0021] In some embodiments, the locking structures are symmetrically arranged.

[0022] As set up above, since the locking structure is symmetrically arranged, the motion rod is evenly stressed, is more stable during the motion process, and moves better in the vertical direction.

[0023] In some embodiments, the locking structure includes a protrusion provided on the motion rod and a sliding groove and a receiving groove provided on the outer rod. The receiving groove includes an introduction wall, a blocking wall and an outlet wall, the introduction wall is arc-shaped and smoothly connected to the first side wall of the sliding groove; the blocking wall is upwardly tilted relative to the radial plane of the outer rod; the outlet wall is a rounded corner between the second side wall of the sliding groove and the blocking wall.

[0024] As set up above, since the introduction wall is arc-shaped and smoothly connected to the first side wall, the protrusion can enter the receiving groove more easily. Since the blocking wall is upturned relative to the radial plane of the outer rod, it can better ensure that the movement rod remains in the knife removal position (that is, the stirring knife can be attracted by the magnetic part and maintain this adsorption state. Since the lead-out wall is the chamfered corner of the second side wall and the blocking wall, a smooth connection is achieved by using the chamfered corner. When the second driving mechanism drives the clamping column of the movement rod, the protrusion can more conveniently exit the receiving groove along the lead-out wall, and then the movement rod can more conveniently move upward.

[0025] In some embodiments, the cup cover assembly also includes an exhaust cover arranged in the center of the cover body, and the moving rod of the knife removing device is penetrated by the exhaust cover and the cover body; the exhaust cover includes an exhaust channel passing through the exhaust cover, and the exhaust channel is arranged around the moving rod.

[0026] As set up above, since the exhaust cover includes an exhaust channel passing through the exhaust cover, the exhaust channel is arranged around the moving rod, so that the air inlet of the exhaust channel is located on the side of the moving rod, and the air outlet of the exhaust channel is located at the edge of the exhaust cover. Therefore, the gas path is longer, which is conducive to reducing noise.

[0027] In some embodiments, the blending cup includes a handle, the handle includes an anti-retreat groove; the cover body includes a telescopic assembly, the telescopic assembly includes a telescopic rod; when the cup cover assembly and the blending cup are in a locked state, the telescopic rod is located in the anti-retreat groove, and the telescopic rod pushes the driving mechanism so that the driving mechanism applies the second force.

[0028] As described above, the telescopic rod is located in the anti-retraction groove, so that the telescopic rod is not easily displaced, etc., thereby ensuring the matching accuracy of the telescopic rod and the second drive mechanism, and further ensuring the movement accuracy of the motion rod. In addition, when the cup cover assembly and the stirring cup are in a locked state, the telescopic rod pushes the drive mechanism, and further, it is more convenient to apply the second force. Moreover, at this time, the cup cover assembly and the stirring cup are locked, and even if the stirring blade is detached, it is still in the closed space formed by the stirring cup and the cup cover assembly, and the stirring blade will not hurt the hand.

[0029] In a second aspect, an embodiment of the present application discloses a food processor, wherein the food processor comprises a driving device and any one of the aforementioned stirring cup assemblies, wherein the driving device drives the stirring blade to rotate in the stirring cup.

[0030] As configured above, the food processor at least has the beneficial effects of the cup cover assembly, which will not be described in detail. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] In order to solve the problem that consumers are easily injured by touching the stirring blade when grabbing the shaft sleeve to take out the stirring blade, the present application discloses a cup cover assembly 10. The cup cover assembly uses the principle of the telescopic mechanism of a ballpoint pen or an automatic pencil. The moving rod extends to suck the stirring blade 20 (equivalent to the extension of the pen core), and the moving rod retracts to release the stirring blade 20 (equivalent to the retracting of the pen core). After release, the stirring blade 20 is assembled to the fixed shaft at the bottom of the stirring cup, so that consumers do not need to touch the stirring blade 20 when taking out the stirring blade 20, avoiding injuries. The structure of the cup cover assembly 10 is described below in conjunction with the relevant drawings.

[0057] See also Figure 1 , Figure 2 and Fig.16 as well as Fig. 20 In the first aspect, the present application discloses a blending cup assembly. The blending cup assembly 100 includes a blending cup 30, a blending blade 20 and a cup cover assembly 10; a fixed shaft 301 is provided at the bottom of the blending cup 30. The cup cover assembly 10 covers the blending cup 30, and includes a cover body 1 and a blade removal device 2. The structure of the cover body 1 is not limited. In the embodiment of the present application, a portion of the blade removal device 2 (as described later) is provided on the cover body 1. For example, see Figure 8The cover body 1 includes a cover body 111, a top cover 112, a PIN bracket 113, a PIN 114 and a cover body sealing ring 115 (used to seal the gap between the cup cover assembly 10 and the mixing cup 30). The assembly of these components and their respective functions can be referred to in the relevant technology and will not be described in detail. The knife removal device 2 includes a motion rod 21, a magnetic member 22 and a driving mechanism 23. The motion rod 21 can move telescopically relative to the cover body 1, which can be understood by using a pen core.

[0058] The magnetic member 22 is used to be magnetically attracted to the stirring blade 20 when the stirring blade 20 is removed, and to be separated from the stirring blade 20 when the stirring blade 20 is installed. Therefore, it is sufficient to be magnetically attracted. For example, when the stirring blade 20 includes iron or magnetic components, the magnetic member 22 can be a magnet. For another example, when the stirring blade 20 is magnetic, the magnetic member 22 is a magnet with a polarity opposite to that of the stirring blade 20. The magnetic member 22 is located at the end of the movement rod 21 relative to the cover body 1. See Fig.10 , Fig.11 , Figure 6 and Figure 2 In an embodiment of the present application, the outer rod 24 includes an outer rod body 241 and an end cap 242. The end cap 242 is inserted into the outer rod body 241. After the movement rod 21 is inserted into the outer rod body 241, the movement rod 21, the outer rod body 241 and the end cap 242 form a receiving space, and the magnetic member 22 is located in the receiving space, so that the magnetic member 22 is located at the end of the movement rod 21 away from the cover body 1. Of course, the end cap 242 and the outer rod body 241 can be constructed as one piece. In other embodiments, the outer rod 24 can also be omitted, and the magnetic member 22 can be embedded in the movement rod 21.

[0059] The structure of the driving mechanism 23 is not limited, and can be understood as a structure that realizes the extension and retraction of the pen core. When the motion rod 21 is subjected to the first force applied by the driving mechanism 23, the magnetic member 22 moves away from the cover body 1 to the knife removal position, at which time the magnetic member 22 can be magnetically attracted to the stirring knife 20.

[0060] As set up as above, during the process of taking out the stirring knife, the stirring knife is magnetically attracted by the magnetic part, and is located at the end of the motion rod relative to the cover body. The consumer's hand is far away from the stirring knife, and the consumer's hand will not touch the stirring knife, thus avoiding injury. Furthermore, because the consumer's hand is far away from the stirring knife 20, even if the stirring knife is very hot after cooking, the stirring knife 20 can be taken out, and the stirring knife 20 can be cleaned in time, thus avoiding the stirring knife 20 from being stuck with residue due to failure to clean it in time. Secondly, during the operation of the food processor, the motion rod 21 is located above the stirring knife 20. During the process of cooking ingredients, even if the stirring knife 20 is lifted up by the ingredients, it will be pushed back by the motion rod 21, thus avoiding the stirring knife 20 from falling out. Finally, during the slurry pouring process, because the stirring knife 20 has been taken out, the risk of the stirring knife 20 falling out is avoided.

[0061] In some embodiments, when the motion rod 21 is subjected to the second force applied by the driving mechanism 23, the magnetic member 22 moves toward the cover body 1 to the knife-off position, at which the magnetic member 22 and the stirring knife 20 are far apart, the stirring knife 20 is not affected by the magnetic force and is separated from the magnetic member 22, and the stirring knife 20 is assembled with the fixed shaft 301. The assembly is described later.

[0062] As set up above, the magnetic part moves toward the cover body to the disengaging position, corresponding to the cup cover assembly covering the stirring cup. In this case, the magnetic part is separated from the stirring blade by the second force. Because the cup cover assembly covers the stirring cup and can block the stirring blade, the separated stirring blade will not hurt your hand.

[0063] In some embodiments, the knife removal device 2 also includes an outer rod 24 assembled on the cover body 1, the movement rod 21 is inserted into the outer rod 24, and a locking structure is provided between the outer rod 24 and the movement rod 21. The specific structure of the locking structure is limited to an embodiment as described later. The movement rod 21 is locked in the knife removal position by the locking structure. The driving mechanism 23 includes a second driving mechanism 232. The second driving mechanism 232 is provided on the cover body 1, and applies the second force to unlock the locking structure. The second driving mechanism 232 also drives the magnetic member 22 to the knife removal position.

[0064] As described above, by setting a locking structure between the moving rod 21 and the outer rod 24, the second driving mechanism 232 applies a second force to unlock the locking structure and drive the magnetic part 22 to the knife disengagement position. In this way, the structure of the cup cover assembly 10 is simple, and the stirring knife 20 is easy to disengage from the magnetic part.

[0065] In some embodiments, the knife removing device also includes an outer rod 24 assembled on the cover body 1, the moving rod 21 is inserted into the outer rod 24, and a locking structure is provided between the outer rod 24 and the moving rod 21; the driving mechanism 23 includes a first driving mechanism 231; the first driving mechanism 231 applies the first force so that the moving rod 21 moves in a vertical direction relative to the outer rod 24 until it is locked by the locking structure to maintain it in the knife removing position.

[0066] As described above, by setting a locking structure between the moving rod 21 and the outer rod 24, the moving rod 21 is moved relative to the outer rod 24 by a first force until the moving rod is locked by the locking structure, so that the magnetic part 22 can be maintained in the knife-removing position, making it easier to attract the stirring knife. Moreover, after attracting the stirring knife 20, because the moving rod 21 is locked, the distance between the magnetic part 22 and the stirring knife 20 can be ensured, thereby ensuring the magnetic force, and the stirring knife 20 is not easy to fall off. In addition, since the driving mechanism includes a first driving mechanism 231 and a second driving mechanism 232, the first driving mechanism 231 applies the first force. The second driving mechanism 232 applies the second force, so that the first driving mechanism and the second driving mechanism are independent of each other, which is conducive to the layout of the first driving mechanism 231 and the second driving mechanism 232.

[0067] As follows, when the first driving mechanism 231 and the second driving mechanism 232 are set, a method for removing and removing the stirring blade 20 is described as follows.

[0068] Remove the mixing blade 20: Figure 1 and Figure 2 and with Fig.16 In contrast, in the unlocked state of the cover 1 and the blending cup 30, the cover 1 is still covering the blending cup 30. At this time, the blending blade 20 is removed. Figure 1 and Figure 2 In the state shown, the driving mechanism 23 applies a first force to the movement rod 21 (the first force is applied by any structure), so that the movement rod 21 Figure 1 and Figure 2 The stirring blade 20 is moved downward, thereby driving the magnetic member 22 to move toward the stirring blade 20 until the magnetic member 22 and the stirring blade 20 are magnetically attracted. Fig.16 As shown, the stirring blade 20 can be taken out from the stirring cup 30.

[0069] Assembly of the stirring blade 20 (ie, the stirring blade 20 and the magnetic member 22 fall off): Fig.16 In the state shown, the cup cover assembly 10 is closed, and the closed state is as shown in FIG. Figure 1 and Figure 2As shown. In this state, the driving mechanism 23 applies a second force (the second force is applied by any structure), and the motion rod 21 drives the magnetic member 22 to move upward under the action of the second force, so that the distance between the magnetic member 22 and the stirring blade 20 increases, until the gravity of the stirring blade 20 is greater than the magnetic force between the stirring blade 20 and the magnetic member 22, so that the stirring blade 20 is separated from the magnetic member 22 (including critical separation or separation state). Subsequently, the fixed shaft 301 is rotated, and the stirring blade 20 is assembled on the fixed shaft 301 by the spiral force of the fixed shaft 301 or the downward pressure of the water flow.

[0070] See also Fig.10 and Fig.11 Combined with Figure 1 , Figure 2 , Fig.16 and Fig. 20 The knife-removing device 2 includes a first elastic member 25, and the first elastic member 25 abuts against the outer rod 24 and the magnetic member 22. When the magnetic member 22 moves away from the cover body 1 to the knife-removing position, the first elastic member 25 is compressed. When the magnetic member 22 moves toward the cover body 1 to the knife-removing position, the first elastic member 25 gradually returns to a natural state.

[0071] As set up above, since the first elastic member 25 is compressed when the moving rod 21 moves to the knife-removing position, correspondingly, during the movement toward the cover body 1, the first elastic member 25 gradually returns to its natural state, and the elastic force generated by the restoration of the natural state causes the locking structure to be unlocked, thereby facilitating the movement of the magnetic member 22 to the knife-removing position.

[0072] See also Fig.10 , Fig.11 and Fig.12 Combined with Figure 1 , Figure 2 , Fig.16 and Fig. 20 The first driving mechanism 231 includes a button 2311 and a second elastic member 2312. The movement rod 21 is in contact with the button 2311 in any manner as long as it can be pressed. In the embodiment of the present application, the movement rod 21 is inserted into the button 2311 to achieve the contact. The opposite ends of the second elastic member 2312 are in contact with the button 2311 and the cover body 1 respectively, and the contact can be direct contact or indirect contact through a fixed sleeve 2313.

[0073] As configured above, the first driving mechanism 231 includes a button 2311 and a second elastic member 2312, which facilitates driving the moving rod 21 so that the moving rod 21 drives the magnetic member 22 to move to the knife-removing position; it is also beneficial to reset the button 2311 and drive the magnetic member 22 to move to the knife-removing position.

[0074] Some embodiments of the second driving mechanism 232 are described as follows:

[0075] See also Figure 3 , Figure 4 , Figure 5 , Fig.10 and Fig.11 The movement rod 21 is provided with a clamping column 211. Figure 8 and Fig. 9 Combined with Figure 3 , Figure 4 , Figure 5 , Fig.10 and Fig.15 The first second driving mechanism 232 shown, and Fig.19 The second type of second driving mechanism 232 is shown. The two types of second driving mechanisms 232 include a locking rod 2321, a first reset member 2322, a second reset member 2323 and a push rod 2324. The first reset member 2322 is connected to the locking rod 2321 and the cover body 1, and the second reset member 2323 is in contact with the push rod 2324 and the cover body 1.

[0076] How the second driving mechanism 232 realizes the knife stripping is described as follows:

[0077] The locking rod 2321 is subjected to an external force (in this embodiment, the external force comes from the telescopic assembly, as described later) and rotates in a first direction in a horizontal plane. The first direction is, for example, a counterclockwise direction. Fig. 9 As shown by arrow A1, the first restoring member 2322 is deformed, the locking rod 2321 pushes the ejector rod 2324 to extend and compress the second restoring member 2323. Figure 3 and Fig.15 The insertion portion 23211 of the locking rod 2321 is inserted into the insertion groove 23241 of the ejector rod 2324 to push the ejector rod 2324. The ejector rod 2324 cooperates with the clamping column 211 through the inclined surface (the ejector rod inclined surface 23242 of the ejector rod 2324 and the clamping column inclined surface) to apply the second force, that is, the horizontal movement of the ejector rod 2324 is converted into the vertical movement of the motion rod 21, see Figure 3, the top rod 2324 moves to the left so that the moving rod 21 moves vertically upward. As a result, the movement of the moving rod 21 drives the magnetic part 22 to move to the knife-off position. At the knife-off position, the distance between the magnetic part 22 and the stirring knife 20 is relatively far, and the magnetic force cannot attract the stirring knife 20. The stirring knife 20 will fall onto the fixed shaft 301 under the action of gravity. Of course, there is no limit to how the stirring knife 20 is assembled with the fixed shaft 301. For example, the stirring knife 20 and the fixed shaft 301 are assembled through a spiral surface, etc., or the fixed shaft 301 is rotated so that the stirring knife 20 is assembled with the fixed shaft 301. When the locking rod 2321 is not subjected to external force, the first reset member 2322 returns to its natural state, which will cause the locking rod 2321 to rotate in a second direction opposite to the first direction, such as Fig. 9 Then, because the locking rod 2321 no longer supports the push rod 2324 after retracting, the push rod 2324 retracts under the action of the second reset member 2323, that is, Figure 3 In the embodiment of the present application, the moving rod 21 moves downward with the magnetic part 22, and is supported by a support member (such as the first elastic member 25 or the second elastic member 2312). In this case, if the mixing knife 20 needs to be taken out, the first driving mechanism is pressed so that the magnetic part 22 attracts the mixing knife 20. In other embodiments, the moving rod 21 may not be supported by a support member (such as the first elastic member 25 or the second elastic member 2312), as long as the moving rod 21 can be moved downward by the first driving mechanism 231 so that the magnetic part 22 attracts the mixing knife 20.

[0078] In the above embodiment, there is no limitation on how to realize the rotation of the locking rod 2321 in the first direction A1 and the second direction A2 by the first restoring member 2322 , for example, Fig. 9 The first restoring member 2322 of the first type of second driving mechanism 232 shown is a torsion spring. Fig.19 The first restoring member 2322 of the second driving mechanism 232 of the second type shown is a tension spring.

[0079] As set up above, by setting the moving rod 21 with a clamping column 211, the second driving mechanism 232 includes a locking rod 2321, a first reset member 2322, a second reset member 2323 and a push rod 2324. Through the cooperation between them, the operation of taking out the mixing knife 20 can be performed only when the second driving mechanism is not under force, ensuring that the consumer's hand will not touch the mixing knife 20 to avoid injury.

[0080] See also Fig.21 , Fig. 22 and Fig.23 Combined with Fig. 20The push rod of the third second driving mechanism 232 is in linear motion to realize the movement of the moving rod 21, but Fig.19 The second second drive mechanism 232 and the first second drive mechanism 232 shown in the figure have respective lock rods 2321 that rotate. Figure 20 to Figure 23 The third type of second driving mechanism 232 is described in more detail as follows:

[0081] The movement rod 21 is provided with a clamping column 211. The second driving mechanism 232 includes a push rod 2325 and a reset member 2326. The reset member 2326 abuts against the push rod 2325 and the cover body 1. Specifically, the cover body 1 is provided with a first blocking portion 11. The push rod 2325 includes a baffle 23251. The reset member 2326 abuts against the baffle 23251 and the first blocking portion 11.

[0082] The push rod 2325 is subjected to external force and moves linearly in a first direction. Fig. 20 , Fig.21 and Fig. 22 Move along the direction of arrow A1 until the push rod 2325 and the clamping column 211 are matched with each other through the inclined surface (such as Fig. 22 As shown, the push rod inclined surface 23252 cooperates with the column inclined surface 2111) to apply the second force, so that the moving rod 21 drives the magnetic part 22 to move to the knife-off position, that is, the push rod 2325 moves in the horizontal direction (which can also be considered as the radial movement of the cover body 1), and the moving rod 21 moves vertically upward to drive the magnetic part 22 to move upward until the knife-off position. In the knife-off position, the magnetic force between the magnetic part 22 and the stirring knife 20 is less than the gravity of the stirring knife 20, so that the stirring knife 20 falls to the fixed shaft 301. When the push rod 2325 is not subjected to external force, the reset member 2326 returns to a natural state so that the push rod 2325 moves linearly in a second direction (arrow A2) opposite to the first direction, and the push rod 2325 retracts. How the moving rod 21 moves up and down is the same as the previous embodiment and will not be repeated.

[0083] As configured above, since the second driving mechanism 232 includes a push rod 2325 and a reset member 2326, the knife removal is achieved by the cooperation between the reset member 2326 and the push rod 2325. The operation of removing the mixing knife 20 can only be performed when the second driving mechanism is not subjected to force, ensuring that the consumer's hands will not touch the mixing knife 20 to avoid injury.

[0084] In some embodiments, the locking structures are symmetrically arranged. In other embodiments, there may be only one locking structure.

[0085] As described above, since the locking structure is symmetrically arranged, the movement rod 21 is evenly stressed, is more stable during movement, and moves better in the vertical direction.

[0086] In some embodiments, see Fig.12 , Fig.10 and Fig.14 The locking structure includes a protrusion 212 provided on the movement rod 21 and a sliding groove 2411 and a receiving groove 2412 provided on the outer rod 24. In the embodiment of the present application, the sliding groove 2411 includes a first side wall 24111 and a second side wall 24112 opposite to each other.

[0087] See also Fig.14 The receiving groove 2412 includes an introduction wall 24121, a blocking wall 24122 and an outlet wall 24123. The introduction wall 24121 is arc-shaped and smoothly connected to the first side wall 24111 of the sliding groove 2411. The blocking wall 24122 is upturned relative to the radial plane of the outer rod 24. The outlet wall 24123 is a rounded corner between the second side wall 24112 of the sliding groove 2411 and the blocking wall 24122.

[0088] As described above, since the introduction wall 24121 is arc-shaped and smoothly connected to the first side wall 24111, the protrusion 212 can more easily enter the receiving groove 2412. Since the blocking wall 24122 is upturned relative to the radial plane of the outer rod 24, it can better ensure that the movement rod 21 is maintained in the knife removal position (that is, the stirring knife 20 can be attracted by the magnetic member 22 and maintain the adsorption state, for example, after the stirring knife 20 is adsorbed, it is not necessary to keep pressing the first driving mechanism 231). Since the outlet wall 24123 is the rounded corner of the second side wall 24112 and the blocking wall 24122, the rounded corner is used to achieve a smooth connection. When the second driving mechanism 232 drives the clamping column 211 of the movement rod 21, the protrusion 212 can more conveniently exit the receiving groove 2412 along the outlet wall 24123, and then the movement rod 21 can more conveniently move upward.

[0089] See also Figure 6 , Figure 7 , Figure 8 and Fig. 9 Combined with Figure 1 and Figure 2 The cup cover assembly 10 includes an exhaust cover 3 disposed at the center of the cover body 1. How the exhaust cover 3 is disposed at the center of the cover body 1 is not limited, for example, see Fig.10 and Fig.12The exhaust cover 3 is provided with a clamping block 39 (a clamping block 39 is provided on the fixed shaft sleeve 2313), and the cover body 1 is provided with a buckle 119. The clamping block 39 and the buckle 119 are clamped together so that the exhaust cover 3 is set at the center of the cover body 1. The structure of the exhaust cover 3 is not limited as long as it can achieve exhaust. In the embodiments of the present application, see Fig.13 and Fig.10 The exhaust cover 3 includes an exhaust upper cover 31, an exhaust lower cover 32 and a switch assembly 33. The exhaust upper cover 31 and the exhaust lower cover 32 are covered, and the switch assembly 33 locks or unlocks the exhaust upper cover 31 and the exhaust lower cover 32. That is, by pressing the buckle plate 331 of the switch assembly 33 and then compressing the deformation member 332, the exhaust upper cover 31 and the exhaust lower cover 32 can be in an unlocked state, and the exhaust upper cover 31 and the exhaust lower cover 32 can be disassembled for easy cleaning. Figure 1 , Figure 2 , Figure 6 as well as Fig. 20 The moving rod 21 of the knife taking device 2 is arranged through the exhaust cover 3 and the cover body 1. Fig.13 The exhaust cover 3 includes an exhaust passage 34 that passes through the exhaust cover 3. The exhaust passage 34 is arranged around the motion rod 21.

[0090] As described above, since the exhaust cover 3 includes an exhaust channel 34 that passes through the exhaust cover, and the exhaust channel 34 is arranged around the motion rod 21, the air inlet 341 of the exhaust channel 34 is located on the side of the motion rod 21, and the air outlet 342 of the exhaust channel 34 is located on the edge of the exhaust cover 3 (in this application, between the mounting cavity accommodating the first drive mechanism 231 and the side), so that the gas path is longer, which is conducive to reducing noise. The flow direction of the gas is as follows: Figure 1 and Fig.13 As shown by the dotted arrow in .

[0091] See also Figure 1 , Figure 6 , Fig.16 and Fig. 20 , the blending cup 30 includes a handle 302. Fig.18 , the handle 302 includes an anti-retraction groove 3021. Figure 8 Combined with Fig.17, the cover body 1 includes a telescopic assembly 13. The telescopic assembly 13 includes a telescopic rod 131. In an embodiment of the present application, the telescopic assembly 13 also includes a telescopic member 132. When the cup cover assembly 10 and the blender cup 30 are in a locked state, the telescopic rod 131 is located in the anti-retreat groove 3021, and the telescopic rod 131 pushes the drive mechanism (such as in the present application, pushes the second drive mechanism 232) so that the drive mechanism (such as in the present application, the drive mechanism is the second drive mechanism 232) applies the second force. Two implementation methods for applying the second force are described as follows:

[0092] The first implementation method: see Fig. 22 and Fig.23 When the cup cover assembly 10 and the blending cup 30 are in the locked state, the telescopic rod 131 is inserted into the anti-retraction groove 3021. At the same time, the telescopic rod 131 is inserted into the pushing groove 23253 of the push rod 2325. The two cooperate through the inclined surfaces (that is, the second force is applied to the second driving mechanism), thereby pushing the push rod 2325 to move linearly to move the movement rod 21 upward.

[0093] Second implementation method: See Fig. 9 and Figure 8 When the cup cover assembly 10 and the blending cup 30 are in a locked state, the telescopic rod 131 pushes the locking rod 2321 (i.e., applies the second force to the second driving mechanism) so that the locking rod 2321 rotates in the direction indicated by the arrow A1. When the cup cover assembly 10 and the blending cup 30 are in an unlocked state, the locking rod 2321 is no longer pushed by the telescopic rod 131, and the locking rod 2321 will move in the direction of the arrow A2 under the action of the first restoring member 2322.

[0094] As described above, by the telescopic rod 131 being located in the anti-retraction groove 3021, the telescopic rod 131 is not easily displaced, etc., thereby ensuring the matching accuracy between the telescopic rod 131 and the second driving mechanism 232 (such as the locking rod 2321 or the push rod 2325 mentioned above), and further ensuring the movement accuracy of the motion rod 21. In addition, when the cup cover assembly 10 and the stirring cup 30 are in a locked state, the telescopic rod 131 pushes the driving mechanism, and further, it is more convenient to apply the second force. Moreover, at this time, the cup cover assembly is locked with the stirring cup, and even if the stirring knife is detached, it is still located in the closed space formed by the stirring cup and the cup cover assembly, and the stirring knife will not hurt the hand.

[0095] It should be noted that when the magnetic member 22 moves to the knife-taking position, the cup cover assembly 10 can be locked with the blending cup 30, or it can be unlocked, as long as the cover on the blending cup 30 can make the magnetic member 22 move away from the cover body 1 (toward the blending knife 20). When the magnetic member 22 moves to the knife-taking position, the cup cover assembly 10 and the blending cup 30 can be locked as described above, or they can be unlocked, and the second force can be applied, for example, the telescopic rod can be matched with the anti-retraction groove.

[0096] In a second aspect, the present application discloses a food processor, which comprises a driving device and any one of the aforementioned blending cup assemblies 100 , wherein the driving device drives the blending blade 20 to rotate in the blending cup 30 .

[0097] As configured above, the food processor at least has the beneficial effects of the cup cover assembly 10, which will not be described in detail.

[0098] The above description is only a preferred implementation mode of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
