[0044] Compared with the prior art, the utility model at least includes the following beneficial effects: the stirring device provided in the embodiment of the present application is provided with a cup body, a cup cover, a tool assembly, a wall scraping assembly and an adjusting member. Among them, the top of the cup body is open, and a stirring chamber is formed inside the cup body, and the food can be put into the stirring chamber from the open. The cover body is provided on the open mouth of the cup body to close the stirring chamber to avoid splashing of the food during the stirring of the food.

[0045] It should be noted that the adjustment condition of the adjusting part can be triggered according to the resistance of the scraping component from the food. In the case of small resistance from the food, the adjusting part adjusts the scraping component to the first operating state, and the food adheres to the inner wall of the cup body due to the centrifugal force generated when the knife assembly is stirred. The scraping component can scrape the food adhered to the inner wall of the cup body to ensure that the food is cut and stirred evenly by the knife assembly, and the scraping effect of the scraping component is ensured. In the case of large resistance from the food, the adjusting part adjusts the scraping component to the second operating state, and the rotation speed of the scraping component is reduced to less than the rotation speed of the knife assembly to reduce the impact on the scraping component when the direction of resistance and the direction of rotation are opposite. Furthermore, when the second rotation speed is 0, the scraping component stops rotating and is stationary relative to the inner wall of the cup body to avoid the scraping component being damaged due to large impact caused by the direction of resistance and the direction of rotation being opposite. When the scraper assembly touches the inner wall of the cup body, it encounters greater resistance and can remain still relative to the cup body, so that the distance between the scraper assembly and the inner wall of the cup body can be set closer, thereby improving the scraping effect, and there is no need to worry about scratching and damage to the scraper assembly and the cup body.

[0064] In order to better understand the above-mentioned technical scheme, the technical scheme of the embodiments of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical scheme of the embodiments of the present application, rather than limitations on the technical scheme of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments may be combined with each other.

[0065] like Figure 1 As shown, according to the first aspect of the embodiment of the present application, a stirring device 100 is proposed, comprising: a cup body 110, wherein a stirring chamber is formed in the cup body 110; a cup cover 120, which is disposed on the cup body 110; a tool assembly 130, which is rotatably disposed in the cup body 110, and is used to chop and stir the food in the stirring chamber; a wall scraping assembly 140, which is connected to the tool assembly 130, and is used to scrape off the food adhered to the inner wall of the cup body 110; an adjusting member 133, which is disposed at the connection between the tool assembly 130 and the wall scraping assembly 140, and is used to adjust the operating state of the wall scraping assembly 140; wherein, when the wall scraping assembly 140 is in a first operating state, the wall scraping assembly 140 rotates synchronously with the tool assembly 130 at a first speed; when the wall scraping assembly 140 is in a second operating state, the wall scraping assembly 140 rotates at a second speed, and the second speed is less than the first speed.

[0066] It is understandable that the stirring device 100 provided in the embodiment of the present application is provided with a cup body 110, a cup cover 120, a tool assembly 130, a wall scraper assembly 140 and an adjusting member 133. Among them, the top of the cup body 110 is open, and a stirring chamber is formed inside the cup body 110, and the food can be put into the stirring chamber from the opening. The cover body is provided on the opening of the cup body 110 to close the stirring chamber to avoid splashing of the food during the stirring of the food. The tool assembly 130 is rotatably provided in the cup body 110 to cut the food and stir the cut food. The wall scraper assembly 140 is connected to the tool assembly 130, and the adjusting member 133 is provided at the connection between the tool assembly 130 and the wall scraper assembly 140. The operating state of the wall scraper assembly 140 can be adjusted by the adjusting member 133 to adapt to a variety of usage scenarios. Specifically, when the adjusting member 133 adjusts the scraper assembly 140 to be in the first operating state, the tool assembly 130 can drive the scraper assembly 140 to rotate synchronously when rotating; when the adjusting member 133 adjusts the scraper assembly 140 to be in the second operating state, the scraper assembly 140 rotates at a second speed, and the speed of the scraper assembly 140 is lower than the speed of the tool assembly 130.

[0067] It should be noted that the adjustment condition of the adjustment member 133 can be triggered according to the resistance from the food to the scraping assembly 140. When the resistance from the food is small, the adjustment member 133 adjusts the scraping assembly 140 to be in the first operating state, and the food is adhered to the inner wall of the cup body 110 by the centrifugal force generated when the knife assembly 130 is stirred. The food adhered to the inner wall of the cup body 110 can be scraped off by the scraping assembly 140 to ensure that the food is cut and stirred evenly by the knife assembly 130, and the scraping effect of the scraping assembly 140 is ensured. When the resistance from the food is large, the adjustment member 133 adjusts the scraping assembly 140 to be in the second operating state, and the rotation speed of the scraping assembly 140 is reduced to be less than the rotation speed of the knife assembly 130, so as to reduce the impact on the scraping assembly 140 when the direction of the resistance is opposite to the direction of rotation. Furthermore, when the second rotation speed is 0, the wall scraper assembly 140 stops rotating and remains stationary relative to the inner wall of the cup body 110, so as to avoid the wall scraper assembly 140 being damaged by a large impact caused by a resistance direction opposite to the rotation direction. After cleaning the food firmly adhering to the inner wall of the cup body 110, the wall scraper assembly 140 can resume rotating.

[0068] It should be noted that, during the process of stirring the ingredients, the ingredients adhere to the inner wall of the cup body 110. If the ingredients adhere firmly and are difficult to remove, they will be stuck between the scraper assembly 140 and the inner wall of the cup body 110. If the scraper assembly 140 continues to rotate, it will be subjected to both rotational force and greater resistance, causing the scraper assembly 140 to be easily twisted and deformed, resulting in damage. In addition, during the process of stirring the ingredients, the knife assembly 130 and the scraper assembly 140 may shake, causing the distance between the scraper assembly 140 and the inner wall of the cup body 110 to change, so that the scraper assembly 140 touches the inner wall of the cup body 110 when rotating. This causes damage to the scraper assembly 140 and the inner wall of the cup body 110. However, the distance between the scraper assembly 140 and the inner wall of the cup body 110 of the present application can be set to be smaller, so there is no need to worry about the scraper assembly 140 scraping the cup body 110, causing damage to the scraper assembly 140 and the cup body. Because when the scraper assembly 140 is subject to greater resistance from the food and the inner wall of the cup body 110, the scraper assembly 140 is stationary relative to the inner wall of the cup body 110, thereby avoiding further damage to the scraper assembly 140 and the inner wall of the cup body 110. In addition, the user can learn from the running state of the scraper assembly 140 that the food currently adhering to the inner wall of the cup body 110 is difficult to clean, and the operation of the stirring device 100 needs to be suspended for cleaning. Or it can be learned that the scraper assembly 140 shakes greatly during operation, and the scraper assembly 140 and the knife assembly 130 need to be adjusted to ensure that the stirring device 100 can work normally in the future and extend its service life.

[0069] For example, the cup body 110 can be made of a transparent material so that when the knife assembly 130 cuts and stirs the food, the user can observe the cutting and stirring degree of the food in the cup body 110. In addition, the situation of the food adhering to the inner wall of the cup body 110 and the working condition of the wall scraping assembly 140 can be observed, so as to determine whether the wall scraping assembly 140 scrapes off the food adhering to the inner wall of the cup body 110 to ensure that the thickness of the food is stirred evenly. In addition, when the wall scraping assembly 140 encounters a large resistance and stops rotating, the user can observe it at the first time and react, such as pausing the operation of the stirring device 100, removing the food firmly adhering to the cup body 110, or checking the shaking of the knife assembly 130, so as to ensure that the wall scraping assembly 140 can rotate synchronously with the knife assembly 130 to scrape off the food adhering to the inner wall of the cup body 110.

[0070] For example, when the scraping assembly 140 encounters a large resistance and stops working, the tool assembly 130 may stop rotating at the same time, and the stirring device 100 may be provided with an alarm system to send out an audible and visual alarm to remind the user that the scraping operation is abnormal and to deal with it in time.

[0071] In some examples, when the resistance encountered by the wall scraping assembly 140 is less than a preset resistance, the adjusting member 133 adjusts the wall scraping assembly 140 to be in a first operating state; when the resistance encountered by the wall scraping assembly 140 is greater than or equal to the preset resistance, the adjusting member 133 adjusts the wall scraping assembly 140 to be in a second operating state.

[0072] It is understandable that a preset resistance may be provided, and the adjustment member 133 may adjust the operation state of the wall scraping assembly 140 according to the resistance encountered by the wall scraping assembly 140 and the preset resistance value. Specifically, when the knife assembly 130 is started to cut and stir the food, the wall scraping assembly 140 is in the first operation state, and the wall scraping assembly 140 and the knife assembly 130 rotate synchronously. In the initial stage of the stirring operation, the food to be cut and stirred is less, and the food adhering to the inner wall of the cup body 110 is less, so the food adhering to the inner wall of the cup body 110 has less resistance to the wall scraping assembly 140 than the preset resistance, and the wall scraping assembly 140 maintains the first operation state, and the wall scraping assembly 140 can rotate synchronously with the knife assembly 130 to scrape off the food adhering to the inner wall of the cup body 110. During the continuous mixing operation, the relatively sticky food adheres to the inner wall of the cup body 110 and is difficult to scrape off and will accumulate on the side wall of the cup body 110 until the gap between the inner wall of the cup body 110 and the wall scraper assembly 140 is blocked, causing the wall scraper assembly 140 to face a gradually increasing resistance from the food. When the resistance is greater than or equal to the preset resistance, the adjustment member adjusts the wall scraper assembly 140 to be in the second operating state. At this time, the wall scraper assembly 140 will stop rotating and remain relatively still with the cup body 110 to prevent the wall scraper assembly 140 from continuing to rotate and being subjected to rotational force and greater resistance, causing the wall scraper assembly 140 to twist and deform, resulting in damage. When the tool assembly 130 or the scraper assembly 140 shakes, causing the scraper assembly 140 to touch the inner wall of the cup body 110, the resistance encountered by the scraper assembly 140 increases rapidly, and the resistance is greater than or equal to the preset resistance, and the scraper assembly 140 stops rotating to avoid further collision with the inner wall of the cup body 110, causing damage to the scraper assembly 140 and the cup body 110.

[0073] In some examples, such as Figures 2 to 4 As shown, the tool assembly 130 includes: a rotating shaft 131, which is arranged on the cup body 110, and the wall scraping assembly 140 is sleeved on the rotating shaft 131; a tool 132, which is sleeved on the rotating shaft 131; and an adjusting member 133, which is arranged at the connection between the wall scraping assembly 140 and the rotating shaft 131, and is used to adjust the state of the wall scraping assembly 140.

[0074] It can be understood that the tool assembly 130 is provided with a rotating shaft 131, a tool 132 and an adjusting member 133. Among them, the rotating shaft 131 is arranged in the cup body 110 and can rotate relative to the cup body 110, and the wall scraping assembly 140 is sleeved on the rotating shaft 131. The tool 132 is sleeved on the rotating shaft 131, and the tool 132 is located below the wall scraping assembly 140. The adjusting member 133 is arranged at the connection between the wall scraping assembly 140 and the rotating shaft 131, and the adjusting member 133 can provide the wall scraping assembly 140 with a fixing force to the rotating shaft 131, and the fixing force is equal to the preset resistance. In the case where the resistance to the wall scraping assembly 140 is less than the fixing force, the adjusting member 133 can fix the wall scraping assembly 140 to the rotating shaft 131, so that the tool 132 and the wall scraping assembly 140 rotate synchronously. When the resistance to the scraper assembly 140 is greater than or equal to the fixing force, the adjusting member 133 cannot fix the scraper assembly 140 to the rotating shaft 131 . At this time, the rotating shaft 131 cannot provide rotational force for the scraper assembly 140 , and the scraper assembly 140 is stationary relative to the inner wall of the cup body 110 .

[0075] It is understandable that a mounting position may be provided on the rotating shaft 131 to mount the cutter 132. The rotating shaft 131 may be connected to the driving member 210, and the driving member 210 drives the rotating shaft 131 to rotate, thereby driving the cutter 132 to rotate, so as to cut and beat the food. The space where the cutter 132 rotates may form a cutting space, and the scraping assembly 140 may scrape off the food adhered to the inner wall of the cup body 110 between the cover and the cutting space.

[0076] Exemplarily, the rotating shaft 131 may be provided with a plurality of mounting positions to install a plurality of cutters 132 to improve the efficiency of cutting and stirring. Specifically, four mounting positions may be provided to install four cutters 132. The cutter 132 may extend in the horizontal direction to improve the cutting ability of the food. The cutter 132 installed at the mounting position of the rotating shaft 131 near the bottom of the cup body 110 is tilted upward away from the end of the rotating shaft 131 to improve the stirring ability of the food. When the food is rotated and cut by the plurality of cutters 132, it will be affected by the collision and rotation of the cutter 132, and will hover inside the cup body 110, and will be affected by gravity and fall back to the bottom of the cup body 110. Under the action of the cutter 132 at the bottom of the cup body 110, it will move upward again and be repeatedly cut and whipped by the plurality of cutters 132. Some other food will adhere to the inner wall of the cup body 110 due to the centrifugal force, and will be scraped back to the cutting space by the scraping assembly 140 to continue cutting and whipping. To ensure that the ingredients are mixed evenly to meet user needs.

[0077] In some examples, such as Figure 2 and Figure 3As shown, the tool assembly 130 further includes: a transmission shaft 134 connected to the rotating shaft 131 , passing through the cup cover 120 , and used to be connected to the driving member 210 ; and a first limiting member disposed between the transmission shaft 134 and the wall scraping assembly 140 .

[0078] It is understandable that the tool assembly 130 is also provided with a transmission shaft 134 and a first stopper. The transmission shaft 134 is connected to the top of the rotating shaft 131, and the cup cover 120 is provided with a through hole, so that the transmission shaft 134 can pass through the cup cover 120 and be connected to the driving member 210. The driving member 210 can drive the transmission shaft 134 to rotate, and the transmission shaft 134 drives the rotating shaft 131 to rotate. The first stopper is arranged between the transmission shaft 134 and the wall scraping assembly 140, and the axial position of the wall scraping assembly 140 relative to the rotating shaft 131 is limited by the first stopper to prevent the wall scraping assembly 140 from axially moving along the rotating shaft 131. Improve the connection stability of the wall scraping assembly 140. Even if the resistance to the wall scraping assembly 140 is greater than the preset resistance, the wall scraping assembly 140 will not fall off the rotating shaft 131, thereby improving reliability.

[0079] In some examples, the adjusting member includes: a blocking member, which is arranged on the circumferential side of the rotating shaft; and a second limiting member, which is arranged on the wall scraping assembly; wherein, when the resistance encountered by the wall scraping assembly is less than a preset resistance, the blocking member is engaged with the second limiting member; when the resistance encountered by the wall scraping assembly is greater than or equal to the preset resistance, the blocking member falls off the second limiting member.

[0080] It is understandable that the adjusting member 133 may be provided with a blocking member and a second limiting member. Among them, the blocking member is arranged on the peripheral side of the rotating shaft 131, and the second limiting member is arranged on the wall scraping assembly 140, and the positions of the blocking member and the second limiting member correspond. The second limiting member can limit the position of the blocking member, and the maximum blocking force of the second limiting member on the blocking member can be used as a fixing force for the synchronous rotation of the rotating shaft 131 and the wall scraping assembly 140. Therefore, the fixing force can be used as a preset resistance. Specifically, when the stirring device 100 is started, the rotating shaft 131 rotates to drive the cutter 132 to rotate, and the cutter 132 rotates to cut and beat the ingredients. At this time, the ingredients adhering to the inner wall of the cup body 110 are less, and the resistance to the wall scraping assembly 140 is less than the fixing force. At this time, the blocking member is connected to the second limiting member, so that the wall scraping assembly 140 can rotate synchronously with the cutter 132. To continuously scrape off the ingredients adhering to the inner wall of the cup body 110. The food falls back into the cutting space, and the cutter 132 continues to cut and stir the food to ensure that the food is cut and stirred evenly, and to ensure the scraping effect of the scraper assembly 140. When the resistance of the scraper assembly 140 is greater than or equal to the fixing force, the resistance of the scraper assembly 140 is greater than the maximum blocking force of the second limiter on the blocking member, causing the blocking member to fall off from the second limiter, so that the scraper assembly 140 cannot continue to rotate synchronously with the cutter 132, and the scraper assembly 140 reduces its rotation speed, or even remains stationary with the inner wall of the cup body 110. This prevents the scraper assembly 140 from being damaged due to a large impact caused by the resistance direction being opposite to the rotation direction, and prevents the scraper assembly 140 from continuously scraping against the inner wall of the cup body 110, thereby extending its service life. After the user cleans the food that is firmly adhered to the inner wall of the cup body 110 and adjusts the shaking of the rotating shaft 131 and the wall scraper assembly 140, the resistance encountered by the wall scraper assembly 140 is smaller than the fixing force, and the blocking member can be engaged with the second limit member. The wall scraper assembly 140 and the cutter 132 rotate synchronously to continuously scrape off the food adhered to the inner wall of the cup body 110.

[0081] In some examples, such as Figure 5 and Fig. 9As shown, the blocking member is a limiting rib 1331, and the limiting rib 1331 is arranged at intervals on the circumferential side of the rotating shaft 131, wherein a limiting space is formed between each adjacent two limiting ribs 1331; the second limiting member includes a connecting ring 1332 and a protrusion 1333, wherein the outer wall of the connecting ring 1332 is connected to the scraping wall assembly 140, and the connecting ring 1332 is sleeved on the limiting rib 1331; the protrusions 1333 are arranged at intervals on the inner wall of the connecting ring 1332, and each of the protrusions 1333 is correspondingly arranged in one of the limiting spaces; wherein, when the resistance to the scraping wall assembly 140 is less than the preset resistance, the protrusion 1333 abuts against the limiting rib 1331; when the resistance to the scraping wall assembly 140 is greater than or equal to the preset resistance, the protrusion 1333 slides out of the limiting space.

[0082] It is understandable that the blocking member may use the limiting rib 1331, and correspondingly, the second limiting member is provided with a connecting ring 1332 and a convex point 1333. Among them, there are a plurality of limiting ribs 1331, and the plurality of limiting ribs 1331 are arranged at intervals on the circumference of the rotating shaft 131, and a limited space is formed between each two adjacent limiting ribs 1331. The scraping wall assembly 140 is connected to the limiting rib 1331 through the connecting ring 1332. Specifically, the scraping wall assembly 140 is connected to the outer wall of the connecting ring 1332, and the inner side of the connecting ring 1332 is sleeved on the limiting rib 1331. The convex point 1333 is provided on the inner wall of the connecting ring 1332, and a plurality of convex points 1333 are provided and are arranged at intervals along the inner wall of the connecting ring 1332. When the connecting ring 1332 is sleeved on the limiting rib 1331, each convex point 1333 can be located in a limiting space. When the convex point 1333 abuts against the limiting rib 1331 on one side, a fixing force can be provided for the connecting ring 1332. The fixing force is equal to the preset resistance. In this way, when the stirring device 100 is started, the rotating shaft 131 rotates to drive the cutter 132 and the limiting rib 1331 to rotate, so that the convex point 1333 abuts against the limiting rib 1331, providing a fixing force for the connecting ring 1332. The cutter 132 rotates to cut and beat the food. At this time, there are fewer food materials adhering to the inner wall of the cup body 110, and the resistance to the wall scraping assembly 140 is less than the fixing force. Thus, the wall scraping assembly 140 can rotate synchronously with the cutter 132. When the resistance to the wall scraping assembly 140 is less than the fixing force, the convex point 1333 can remain in contact with the limiting rib 1331, and the wall scraping assembly 140 and the cutter 132 rotate synchronously to continuously scrape off the food materials adhering to the inner wall of the cup body 110. The food falls back into the cutting space, and the cutter 132 continues to cut and stir the food, so as to ensure that the food is cut and stirred evenly, and to ensure the scraping effect of the scraping assembly 140.

[0083] When the resistance to the scraper assembly 140 is greater than or equal to the fixing force, the protrusion 1333 will detach from the limiting rib 1331, and the protrusion 1333 will slide out of the current limiting space and slide into the adjacent limiting space. When the protrusion 1333 continues to be subject to greater resistance, the protrusion 1333 will continue to slide out of the current limiting space and slide into the adjacent limiting space. As a result, the scraper assembly 140 will not rotate synchronously with the cutter 132, and will remain stationary with the inner wall of the cup body 110. This prevents the scraper assembly 140 from being damaged due to the resistance direction being opposite to the rotation direction, and prevents the scraper assembly 140 from being continuously scraped against the inner wall of the cup body 110, thereby extending the service life. After the user cleans the food that is firmly adhered to the inner wall of the cup body 110 and adjusts the shaking of the rotating shaft 131 and the scraper assembly 140, the resistance encountered by the scraper assembly 140 is smaller than the fixing force, and the protrusion 1333 can remain in contact with the limiting rib 1331. The scraper assembly 140 and the cutter 132 rotate synchronously to continuously scrape off the food adhered to the inner wall of the cup body 110.

[0084] For example, the protrusion 1333 may be hemispherical, and the tip of the hemispherical protrusion 1333 faces the opening of the limiting space. When the resistance of the scraping wall assembly 140 is greater than or equal to the fixing force, the protrusion 1333 can be smoothly separated from the limiting rib 1331 to avoid strong scraping force and damage to the protrusion 1333 and the limiting rib 1331. In addition, the protrusion 1333 can be made of elastic material to avoid serious wear of the protrusion 1333 and the limiting rib 1331 and shorten the service life. Specifically, when the protrusion 1333 gradually detaches from the limiting rib 1331, the protrusion 1333 is subjected to pressure and elastically deforms. When the central axis of the protrusion 1333 abuts against the limiting rib 1331, the pressure on the protrusion 1333 is the greatest and the deformation is the greatest. Subsequently, as the protrusion 1333 slides into the adjacent limiting space, the pressure on the protrusion 1333 gradually decreases and the deformation gradually decreases until the protrusion 1333 slides into the adjacent limiting space and the protrusion 1333 returns to its original state.

[0085] In some examples, such as Figure 2 and Figure 3 As shown, the first limiting member is a limiting ring 135 , which is sleeved on the rotating shaft 131 , and an outer diameter of the limiting ring 135 is greater than an inner diameter of the connecting ring 1332 .

[0086] It is understandable that the first limiting member may be a limiting ring 135. The limiting ring 135 may be sleeved on one end of the rotating shaft 131 close to the transmission shaft 134. A conical surface is formed from the top of the rotating shaft 131 to the position of the rotating shaft 131 for placing the blade, and the cross section of the conical surface gradually increases in the extending direction from the opening of the cup body 110 to the bottom surface of the cup body 110. The connecting ring 1332 is sleeved on the limiting rib 1331, and the inner diameter of the connecting ring 1332 is less than or equal to the outer diameter of the rotating shaft 131 at one end of the limiting rib 1331 close to the bottom of the cup body 110, so as to limit the axial freedom of the bottom of the connecting ring 1332. The outer diameter of the limiting ring 135 is greater than the inner diameter of the connecting ring 1332, so as to limit the axial freedom of the top of the connecting ring 1332. The connection ring 1332 is axially fixed by the limiting ring 135 and the rotating shaft 131 to prevent the wall scraping assembly 140 from axially moving during rotation, thereby improving reliability. In addition, such a setting makes assembly and disassembly quick and simple, thereby improving efficiency.

[0087] In some examples, such as Figures 6 to 8 As shown, the wall scraping assembly 140 includes: a connecting rod 141 connected to the connecting ring 1332 along the radial direction of the connecting ring 1332; and a scraping rod 142 connected to one end of the connecting rod 141 close to the cup body 110.

[0088] It can be understood that the wall scraping assembly 140 is provided with a connecting rod 141 and a scraping rod 142. Among them, the connecting rod 141 is connected to the connecting ring 1332, and a plurality of connecting rods 141 can be provided, and the plurality of connecting rods 141 are arranged at intervals along the radial direction of the connecting ring 1332, and a scraping rod 142 is provided at one end of each connecting rod 141 close to the cup body 110 to scrape off the food adhering to the inner wall of the cup body 110, thereby improving the wall scraping efficiency.

[0089] Exemplarily, the connecting rod 141, the connecting ring 1332 and the scraper rod 142 can be made by an integrated injection molding process to reduce the number of parts and improve the structural strength. Two connecting rods 141 can be provided, and the angle between the two connecting rods 141 is 180°. The side of the scraper rod 142 close to the cup body 110 can be made of a soft rubber material. When the scraper rod 142 scrapes the inner wall of the cup body 110, it can be in soft contact with the cup body 110, deform to absorb the impact, avoid scratching the cup body 110 and the scraper rod 142, and extend the service life.

[0090] Exemplarily, along the projection of the axial direction of the above-mentioned connecting ring 1332, the inclination angle from the top to the bottom of the above-mentioned scraper rod 142 is greater than the inclination angle of the inner wall of the cup body 110. With such a configuration, the distance between the top of the scraper rod 142 and the inner wall of the cup body 110 can be smaller than the distance between the bottom of the scraper rod 142 and the inner wall of the cup body 110. With such a configuration, the scraper rod 142 can provide a downward extrusion force to the food adhering to the inner wall of the cup body 110, and the food can be squeezed downward into the cutting space while scraping the food. Avoid the situation where the food blocks the gap between the scraper rod 142 and the inner wall of the cup body 110, resulting in the scraper rod 142 being subjected to a resistance greater than the preset resistance. Ensure that the scraper assembly 140 can continuously and stably scrape the food on the inner wall of the cup body 110.

[0091] In some examples, the distance between the scraper rod 142 and the inner wall of the cup body 110 is greater than or equal to 1 mm and less than or equal to 4 mm.

[0092] It is understandable that, since the profile of the scraper rod 142 on the side close to the cup body 110 can be regarded as parallel to the profile of the inner wall of the cup body 110, the distance between the scraper rod 142 and the inner wall of the cup body 110 can be set to be smaller to obtain a better scraping effect. Specifically, the distance between the scraper rod 142 and the inner wall of the cup body 110 is greater than or equal to 1 mm and less than or equal to 4 mm. Among them, the distance between the scraper rod 142 and the inner wall of the cup body 110 is greater than or equal to 1 mm, which ensures that a safe distance is left between the scraper rod 142 and the inner wall of the cup body 110, preventing the scraper rod 142 from scraping the cup body 110, and can scrape away food with a thickness greater than 1 mm that is adhered to the inner wall of the cup body 110, and the distance between the scraper rod 142 and the inner wall of the cup body 110 is less than or equal to 4 mm, preventing the scraper rod 142 from being too far away from the inner wall of the cup body 110, and failing to scrape away food with a thin thickness that is adhered to the inner wall of the cup body 110, thereby ensuring the scraping effect.

[0093] In some examples, such as Figures 6 to 8 As shown, the wall scraping assembly 140 also includes: a push plate 143, which is connected to the side of the connecting rod 141 close to the tool 132, and the minimum distance between the push plate 143 and the cup body 110 is smaller than the distance between the side of the scraping rod 142 close to the cup body 110 and the cup body 110.

[0094] It is understandable that the wall scraping assembly 140 is also provided with a push plate 143. The push plate 143 is connected to the side of the connecting rod 141 close to the tool 132, and is arranged below the scraping rod 142 along the axial direction of the connecting ring 1332. There is a gap between the side of the push plate 143 close to the rotating shaft 131 and the rotating shaft 131 to ensure that the rotating shaft 131 can operate normally and avoid interference. At the same time, there is also a gap between the side of the push plate 143 away from the rotating shaft 131 and the inner wall of the cup body 110. Specifically, the minimum distance between the push plate 143 and the cup body 110 is the distance between the side of the push plate 143 close to the cup body 110 and the closest point to the inner wall of the cup body 110 and the inner wall of the cup body 110. This distance is smaller than the distance between the side of the scraping rod 142 close to the cup body 110 and the cup body 110. That is, the gap between the push plate 143 and the inner wall of the cup body 110 is larger than the gap between the scraper rod 142 and the inner wall of the cup body 110. This arrangement prevents the push plate 143 from scraping against the cup body 110 when rotating, and protects the push plate 143 and the inner wall of the cup body 110. The push plate 143 can extend toward the bottom of the cup body 110. When the cutter assembly 130 is running to cut and stir the food, the chopped food will swirl in the cup body 110 along the rotation direction of the rotating shaft 131, and some of the food will collide with the push plate 143, thereby generating thrust to push the push plate 143 to rotate along the rotation direction of the rotating shaft 131. The thrust generated can provide power for the scraper assembly 140 to resist resistance, provide the processing capacity of the scraper assembly 140, and ensure that the scraper assembly 140 can continuously scrape the food adhering to the inner wall of the cup body 110.

[0095] It should be noted that when the scraper assembly 140 touches the food material that is firmly adhered to the inner wall of the cup body 110, the resistance it encounters is relatively large, which is easily greater than or equal to the preset resistance, causing the scraper assembly 140 to be stationary relative to the cup body 110. The swirling food material provides thrust for the push plate 143, which is converted into power for the scraper assembly 140 to offset part of the resistance, so that the resistance encountered by the scraper assembly 140 is less than the preset resistance, so that the scraper assembly 140 can rotate synchronously with the knife assembly 130, ensuring that the scraper assembly 140 can continue to scrape off the food material that is firmly adhered to the inner wall of the cup body 110. When the scraper assembly 140 scrapes against the inner wall of the cup body 110, the resistance encountered is much greater than the preset resistance. Even if the push plate 143 provides a driving force for the scraper assembly 140, it cannot offset the resistance encountered, and the scraper assembly 140 is stationary relative to the cup body 110, to remind the user to make adjustments as soon as possible so that the scraper assembly 140 can operate normally.

[0096] In some examples, along the axial projection of the connecting ring 1332, the scraper rod 142 extends toward the cup cover 120, and the push plate 143 extends toward the bottom of the cup body 110; wherein a scraping space is formed between the scraper assembly 140 and the inner wall of the cup body 110, and the height of the scraping space is the distance between one end of the scraper rod 142 close to the cup cover 120 and one end of the push plate 143 close to the bottom of the cup body 110.

[0097] It can be understood that, in the projection direction along the axial direction of the connecting ring 1332, the scraper rod 142 can extend toward the cup cover 120, so that part of the scraper rod 142 can be located at one end of the connecting rod close to the cup cover 120, to ensure that the scraper rod 142 can scrape the inner wall of the corresponding cup body 110 remaining between the connecting rod and the cup cover 120. Reduce the residue of food in the cup cover 120. At the same time, the push plate 143 can extend toward the bottom of the cup body 110, and the bottom of the push plate 143 is higher than the top of the knife. It can ensure that the push plate 143 has a sufficient expansion area and avoids collision with the knife. The push plate 143 can collide with the food circling in the cup body 110 to provide thrust to the push plate 143, which is converted into power for the wall scraper assembly 140 to offset part of the resistance, so that the resistance of the wall scraper assembly 140 is less than the preset resistance, so that the wall scraper assembly 140 can rotate synchronously with the knife assembly 130, ensuring that the wall scraper assembly 140 can continuously scrape the food that is firmly adhered to the inner wall of the cup body 110. In addition, the push plate 143 can scrape the food that is adhered to the inner wall of the cup body 110 and protrudes higher, further ensuring the scraping effect of the food.

[0098] It should be noted that a scraping space may be formed between the scraping assembly 140 and the inner wall of the cup body 110, and the scraping assembly 140 may scrape the food adhering to the inner wall of the cup body 110 in the scraping space. Specifically, the height dimension of the scraping space is the distance between the end of the scraping rod 142 close to the cup cover 120 and the end of the push plate 143 close to the bottom of the cup body 110. The contour of the scraping space close to the rotating shaft is composed of the profile of the scraping rod 142 close to the cup body 110 and the profile of the push plate 143 close to the cup body 110.

[0099] In some examples, such as Fig.11 As shown, a spoiler rib 111 is formed on the inner wall of the cup body 110 , and the height of the spoiler rib 111 at one end close to the cup cover 120 is lower than the height of the end of the push plate 143 connected to the connecting rod.

[0100] It is understandable that the inner wall of the cup body 110 may be formed with a spoiler rib 111. When the cutter rotates, it can cut and beat the food in the cutting space. Under the rotation of the cutter, the food and the cutter will move in the same direction, resulting in a smaller contact probability between the food and the blade, so that the food cannot be chopped. The spoiler rib 111 can disrupt the eddy current in the cup body 110, so that the food can fully collide with the cutter, thereby improving the cutting and stirring effect. And the height of the end of the push plate 143 close to the connecting rod is higher than the height of the end of the spoiler rib 111 close to the cup cover 120, and the height of the end of the push plate 143 away from the connecting rod is lower than the height of the end of the spoiler rib 111 close to the cup cover 120. So that part of the spoiler rib 111 is located in the scraping space. In this way, the spoiler rib 111 can have a sufficient length to disrupt the eddy current in the cup body 110, and the push plate 143 can scrape the food at the part of the spoiler rib 111 adhering to the scraping space.

[0101] In some examples, along the axial projection of the connecting ring 1332 , the inclination angle of the profile of the side of the push plate 143 close to the cup body 110 is substantially consistent with the inclination angle of the profile of the inner wall of the cup body 110 .

[0102] It is understandable that the push plate 143 can also scrape off some of the food adhering to the inner wall of the cup body 110. In order to better scrape off the food adhering to the inner wall of the cup body 110, the shape of the push plate 143 close to the cup body 110 fits the shape of the inner wall of the cup body 110. Specifically, in the projection along the axial direction of the connecting ring 1332, the inclination angle of the profile of the side of the push plate 143 close to the cup body 110 is substantially the same as the inclination angle of the profile of the inner wall of the cup body 110, thereby increasing the scraping area of ​​the push plate 143 and improving the scraping effect on the food. And fitting the shape of the inner wall of the cup body 110 can prevent the push plate 143 from having protruding points scraping the cup body 110.

[0103] In some examples, the minimum distance between the push plate 143 and the cutter 132 is greater than or equal to 2 mm and less than or equal to 5 mm.

[0104] It can be understood that, along the projection of the axis direction of the above-mentioned connecting ring 1332, the minimum distance between the push plate 143 and the cutter 132 is the distance between the bottom end of the push plate 143 and the cutter 132 closest to the cup cover 120, and the minimum distance between the push plate 143 and the cutter 132 is greater than or equal to 2mm, so as to ensure that there is enough clearance between the cutter 132 and the push plate 143, to avoid the cutter 132 cutting the push plate 143 when rotating, resulting in damage to the cutter 132 and the push plate 143, and to improve reliability. The minimum distance between the push plate 143 and the cutter 132 is less than or equal to 5mm, to avoid excessive clearance, compress the cutting space of the cutter 132, reduce the cutting and stirring efficiency, and ensure that the stirring device 100 has a small volume while having better working performance.

[0105] like Fig.10 and Fig.11 As shown, according to the second aspect of the embodiment of the present application, a food processing device 200 is proposed, comprising: a stirring device 100 as described in any one of the above technical solutions; a driving member 210, which is arranged on the above cup cover 120, and the above tool assembly 130 is passed through the above cup cover 120 and connected to the above driving member 210.

[0106] It is understandable that the food processing device 200 is provided with the stirring device 100 described in any one of the above technical solutions, and therefore has all the beneficial effects of the above stirring device 100, which will not be described in detail here. The driving member 210 is provided on the cup cover 120, and the transmission shaft 134 of the knife assembly 130 passes through the cup cover 120 and is connected to the driving member 210. The operation of the driving member 210 can drive the transmission shaft 134 to rotate, thereby driving the rotating shaft 131, the knife 132 and the scraping assembly 140 to rotate, so as to achieve cutting and stirring of the food.
