[0002] With the development of society and advancements in technology, people's demands for a higher quality of life are constantly evolving, and kitchen appliances are constantly being upgraded. Making your own ice cream with your favorite flavor meets people's culinary needs for healthy food. Among these, ice cream makers, as innovative kitchen appliances, have gradually entered the homes of the general public. These products are primarily used to make a variety of ice cream, smoothies, milkshakes, and other flavors. Currently, most ice cream makers on the market are commercial models, with only a few brands for home use.

[0003] In the prior art, the stirring blade of a household ice cream machine can only automatically advance but not automatically retract, resulting in the blade easily falling off and being difficult to clean. There are two types of blade falling off phenomena: first, the blade easily falls off during the ice cream making process; second, the blade easily falls off during the ice cream making process due to a power outage or the consumer mistakenly forcing the machine on or off. Because ice cream ingredients have a certain viscosity, if the stirring blade falls off during the ice cream making process, the high-speed stirring blade will tilt at the moment of falling off, scratching the inner wall of the stirring cup. In severe cases, the stirring cup will be damaged, and in mild cases, hardware or plastic powder particles will be scraped out of the stirring cup and mixed into the ingredients, posing a health and safety hazard to the user. If the stirring blade falls off and buries itself in the ingredients, it becomes very difficult to remove the stirring blade from the ingredients in order to make ice cream again. The stirring blade head and the blade head connection hole will be covered with ice cream ingredients, making cleaning very troublesome. Utility Model Content

The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] Please refer to Figures 1-11 , an embodiment of the utility model provides an ice cream machine 100, and the ice cream machine 100 includes a shell 110, a drive assembly 120, a stirring assembly 130 and a cup body assembly 140. The drive assembly 120 is installed in the shell 110; the stirring assembly 130 includes a stirring shaft 131 and a cutter head 132, and the drive assembly 120 is connected to the stirring shaft 131; the cup body assembly 140 is connected to the shell 110, and the cutter head 132 is arranged in the cup body assembly 140; the ice cream machine 100 has a locked state and an unlocked state, and the drive assembly 120 drives the stirring shaft 131 to rotate and / or lift to realize automatic switching between the locked state and the unlocked state, and the locked state is configured as: the cutter head 132 is assembled on the stirring shaft 131, and the unlocked state is configured as: the cutter head 132 is assembled in the cup body assembly 140. Exemplarily, in this embodiment, the drive assembly 120 realizes automatic feed and automatic retraction of the cutter head 132 by driving the stirring shaft 131 to lift and rotate. Specifically, as Figure 6 The stirring assembly 130 shown is a schematic diagram of a locked state, at which time the stirring assembly 130 can be used to obtain food in the cup assembly 140 .

[0040] Please refer to Figure 4 、 Figure 5 and Figure 6The blade 132 is automatically assembled on the stirring shaft 131 when the driving assembly 120 drives the stirring shaft 131 to rise. At this time, the blade 132 is separated from the stirring shaft 131 and assembled on the cup body assembly 140 again, thereby realizing automatic advance and retraction of the blade 132. In addition, in the unlocked state, the user can remove the cup cover 1412 together with the blade 132, which is convenient for cleaning the blade 132. The stirring shaft 131 and the blade 132 of the present application are connected by the connecting head 133. The cooperation between the mounting buckle 1331 and the limiting protrusion 1321 ensures that the connection of the blade 132 is firm, thus preventing the blade 132 from falling off.

[0041] Please refer to Figure 6 、 Figure 9 and Figure 10 In one possible embodiment, the stirring assembly 130 further includes a connector 133, which is connected to the stirring shaft 131. The connector 133 has a mounting buckle 1331 for forming a connection with the cutter head 132. Exemplarily, the connector 133 is cylindrical, and the connector 133 is a hollow structure as a whole. The connector 133 is mounted on the stirring shaft 131 by a threaded connection. The connector 133 and the cutter head 132 are connected by the mounting buckle 1331. Since the cutter head 132 is reliably connected to the stirring shaft 131 during operation, the cutter head 132 will not be buried in the food after falling off and will be difficult to remove. In addition, the cutter head 132 is not provided with structures such as holes and grooves. After the cutter head 132 has made food, there is no food residue on the cutter head 132. It only needs to be rinsed with water to clean the surface of the cutter head 132, which makes cleaning more convenient and easy.

[0042] Please refer to Figure 6 、 Figure 9 and Figure 10In one possible embodiment, the mounting buckle 1331 forms a limiting groove 1332, and a plurality of mounting buckles 1331 are provided. A guide groove 1333 is formed between adjacent mounting buckles 1331, and the guide groove 1333 is connected to the limiting groove 1332; the cutter head 132 has a limiting boss 1321 that cooperates with the limiting groove 1332. For example, in this embodiment, four mounting buckles 1331 are provided, and the four mounting buckles 1331 are evenly distributed around the circumference. The guide grooves 1333 on the connector 133 gradually increase in size from the end near the stirring shaft 131 toward the end near the blade head 132. The provision of the guide grooves 1333 facilitates the entry of the limiting protrusion 1321. In addition, it should be noted that the end of the mounting buckle 1331 near the blade head 132 has almost no thickness or a very small thickness. Such a structure facilitates the limiting protrusion 1321 to enter the limiting groove 1332 from the guide groove 1333 to complete the locking of the blade head 132 regardless of the position of the stirring shaft 131. When the stirring assembly 130 of the present application is in operation, the blade head 132 always rotates in the clockwise direction to ensure that the blade head 132 does not fall out of the limiting groove 1332 during operation. The limiting protrusion 1321 is a cylindrical protrusion protruding from the surface of the blade head 132.

[0043] Please refer to Figure 4 、 Figure 5 and Figure 6 In one possible embodiment, the cup body assembly 140 includes a cup body part 141, a fixing frame 142 and an elastic member 143. The fixing frame 142 is slidably installed in the cup body part 141, and the elastic member 143 abuts between the cup body part 141 and the fixing frame 142. For example, it should be noted that when the blade is advanced, the stirring shaft 131 descends, and when the limiting protrusion 1321 enters the limiting groove 1332, the fixing frame 142 does not move. When the blade needs to be retracted, since the connection between the connecting head 133 and the blade head 132 is still in place, the blade head 132 will drive the fixing frame 142 to rise. At this time, the fixing frame 142 will drive the stirring assembly 130 to rotate relative to the cup body part 141 while rising, until the blade head 132 falls off the stirring shaft 131, and the fixing frame 142 will descend to its original position. It is understandable that when the fixing frame 142 rises, the elastic member 143 contracts under pressure. When the cutter head 132 falls off the stirring shaft 131 , the contraction force of the elastic member 143 is released, causing the fixing frame 142 to return to its original position.

[0044] Please refer to Figure 6 、 Figure 7 and Figure 8In one possible embodiment, the fixing frame 142 is provided with a first guide portion 1421, and the cup body part 141 includes a second guide portion 1412A that cooperates with the first guide portion 1421. The first guide portion 1421 cooperates with the second guide portion 1412A so that the fixing frame 142 rotates relative to the cup body part 141 when sliding.

[0045] Please refer to Figure 6 、 Figure 7 and Figure 8 In one possible embodiment, the first guide portion 1421 is configured as a spirally arranged ridge, and the second guide portion 1412A is configured as a spirally arranged groove. Exemplarily, when the fixing frame 142 slides, the fixing frame 142 can rotate relative to the cup body part 141. The main purpose of this design is to ensure that the rotation and positioning of the cutter head 132 can be smoothly achieved during the installation and disassembly process of the cutter head 132, avoiding damage or jamming caused by excessive friction or resistance. The spiral setting is to enable the fixing frame 142 to rotate relative to the cup body part 141 through the cooperation of the spiral ridge and the spiral groove while the fixing frame 142 moves relative to the cup body part 141. In addition, it should be noted that the first guide portion 1421 can also be configured as a spirally arranged groove, and the second guide portion 1412A can be configured as a spirally arranged ridge.

[0046] Please refer to Figure 6 、 Figure 7 and Figure 8 The ice cream machine 100 of the present application is designed with a purely mechanical automatic blade feed and retraction structure, including a mounting buckle 1331, a first guide portion 1421, and a second guide portion 1412A, which can achieve automatic alignment first, and then complete blade feed and retraction. This structure effectively solves the problem of the existing technology that the mixing blade can only achieve automatic feed but not automatic retraction, and avoids the problem that the mixing blade is easy to fall off and difficult to clean.

[0047] Please refer to Figure 4 、 Figure 5 and Figure 6In one possible embodiment, the cup body part 141 includes a cup body 1411 and a cup cover 1412 connected to the cup body 1411. The cup body assembly 140 also includes a magnetic member, which is connected to the fixing frame 142, and an elastic member 143 abuts between the fixing frame 142 and the cup cover 1412. Exemplarily, the elastic member 143 is a compression spring and the magnetic member is a permanent magnet. The function of the magnetic member is to fix the cutter head 132, that is, the cutter head 132 is made of a material that can be attracted by a magnet, or a matching block that can be attracted by a magnetic member is provided on the cutter head 132. The cup cover 1412 and the cup body 1411 are connected in a detachable manner, for example, by a threaded connection or a snap-on structure. This makes it easy for the user to remove the cup cover 1412 together with the cutter head 132, making it easier to clean the cutter head 132. The cup body 1411 is cylindrical and is used to hold ingredients that need to be stirred.

[0048] Please refer to Figure 2 and Figure 3In one possible embodiment, the drive assembly 120 includes a rotary drive component 121, a lifting drive component 122, and a mounting plate 123. The lifting drive component 122 is mounted on the housing 110 and connected to the mounting plate 123. The rotary drive component 121 is mounted on the mounting plate 123 and is in transmission connection with the stirring shaft 131. The rotary drive component 121 is used to drive the stirring shaft 131 to rotate, and the lifting drive component 122 is used to drive the mounting plate 123 and the stirring shaft 131 to rise and fall. For example, the rotary drive component 121 includes a rotary motor 1211, a belt 1212, a small pulley 1213, and a large pulley 1214. The rotary motor 1211 is fixed to the housing 110, the small pulley 1213 is mounted on the rotary motor 1211, the large pulley 1214 is fixedly mounted on the stirring shaft 131, and the belt 1212 is in transmission connection between the large pulley 1214 and the small pulley 1213. It should be noted that the rotating motor 1211 does not rise or fall, and the length of the pulley portion of the small pulley 1213 should be greater than or equal to the lifting range. That is, during the lifting process, the contact point between the belt 1212 and the pulley portion of the small pulley 1213 will change. In other words, the rotating drive component 121 is a belt 1212 transmission mechanism. The structure of the belt 1212 transmission mechanism is relatively simple, and the manufacturing and maintenance costs are low. And because the contact between the belt 1212 and the wheel is flexible, the noise generated by the belt 1212 transmission mechanism during operation is relatively small. The lifting drive component 122 includes a lifting motor 1221 and a ball screw 1222. The lifting motor 1221 is mounted on the housing 110, and the ball screw 1222 is fixedly mounted on the lifting motor 1221. The mounting plate 123 is connected to the ball screw 1222. The lifting motor 1221 drives the ball screw 1222 to rotate, causing the mounting plate 123 to rise and fall, thereby driving the stirring assembly 130 fixed on the mounting plate 123 to rise and fall. It can be understood that the mounting plate 123 is equivalent to a slider that cooperates with the ball screw 1222. In other words, the lifting drive component 122 is a ball screw 1222 transmission mechanism. The ball screw 1222 transmission mechanism has high precision, which is conducive to controlling the height of the lifting and lowering of the stirring assembly 130, thereby further avoiding the risk of the cutter head 132 colliding with the inner wall of the cup body 1411. The driving assembly 120 also includes a guide column 124, which is mounted on the shell 110 and is provided with four. The mounting plate 123 is slidably mounted on the guide column 124. The function of the guide column 124 is to ensure that the mounting plate 123 and the stirring assembly 130 always move in the vertical direction during the lifting process without deviation, and further ensure that the cutter head 132 does not tilt or deflect during the process, thereby reducing the risk of scratching the inner wall of the cup body assembly 140.

[0049] Please refer to Figure 11In one possible embodiment, the ice cream machine 100 further includes a controller 150, an in-position switch 160, an upper limit switch 170, and a lower limit switch 180. The controller 150 is electrically connected to the in-position switch 160, the upper limit switch 170, the lower limit switch 180, the rotary drive component 121, and the lifting drive component 122, respectively. The in-position switch 160 is configured to trigger the in-position switch 160 to control the start and stop of the rotary drive component 121 when the agitator shaft 131 reaches a preset position. In this embodiment, the in-position switch 160, the upper limit switch 170, and the lower limit switch 180 are contact sensors. The upper limit switch 170 and the lower limit switch 180 are used to limit the highest and lowest positions of the lifting drive component 122. The in-position switch 160 is used to detect the preset position. When the agitator shaft 131 reaches the preset position, the rotary motor 1211 is started when the agitator shaft 131 advances and is stopped when the agitator shaft retracts. Specifically, the preset position is configured as follows: when the cutter head 132 is fixed to the cup cover 1412 by the magnetic member, and the limiting boss 1321 is just located in the limiting groove 1332, it is the preset position. Figure 4 The position where the stirring assembly 130 stops is the preset position mentioned above. Specifically, the controller 150 is electrically connected to the rotating motor 1211 and the lifting motor 1221 respectively, that is, the controller 150 is used to control the rotating motor 1211 and the lifting motor 1221 to rotate and stop rotating.

[0050] Please refer to Figure 12 The second object of the present invention is to provide a control method for an ice cream machine 100, which is used to control the ice cream machine 100, comprising:

[0051] The controller 150 controls the lifting drive component 122 to start, so as to drive the stirring shaft 131 downward;

[0052] The stirring shaft 131 continues to descend and enters the limiting groove 1332 through the guide groove 1333;

[0053] After the stirring shaft 131 descends to the preset position, the in-position switch 160 is triggered. The in-position switch 160 sends a first control signal to control the rotation drive component 121 to start and drive the stirring shaft 131 to rotate, so that the cutter head 132 is connected to the stirring shaft 131.

[0054] The stirring shaft 131 continues to descend to separate the blade head 132 from the cup body assembly 140 and enter a locked state; illustratively, after entering the locked state, the food in the cup body 1411 can be stirred.

[0055] After the lower limit switch 180 is triggered, the lower limit switch 180 sends a third control signal, and the lifting drive component 122 drives the stirring assembly 130 to rise to the preset position, triggering the in-position switch 160. The in-position switch 160 sends a second control signal to control the rotation drive component 121 to stop running;

[0056] The lifting drive component 122 drives the stirring assembly 130 and the fixing frame 142 to continue to rise, and the fixing frame 142 rotates relative to the cup body component 141 until the cutter head 132 is separated from the stirring shaft 131 and enters the unlocked state;

[0057] The lifting drive component 122 continues to rise and triggers the upper limit switch 170. The upper limit switch 170 sends a third control signal to control the lifting drive component 122 to stop running.

[0058] Please refer to Figure 12 The ice cream machine 100 has the following process for cutting and retracting:

[0059] Step 1: The connector 133 is fixed to the stirring shaft 131 through a threaded connection, and the blade head 132 is adsorbed on the bottom surface of the fixing frame 142 under the magnetic force of the magnetic member (the magnetic member is fixed on the fixing frame 142).

[0060] Step 2: The connector 133 moves downward under the drive of the lifting motor 1221. As the cutter head 132 is attracted by the magnetic force of the magnetic part, the buckle position (with a guide structure) on the connector 133 connects with the limit boss 1321 on the cutter head 132, thus completing the automatic feed process. Then, by triggering the in-position switch 160, the rotary motor 1211 starts to rotate and drives the cutter head 132 to rotate. The cutter head 132 will complete the buckle self-locking with the connector 133, so that the cutter head 132 will not fall off during operation or sudden power failure and reset. At this time, the cutter head 132 starts to rotate and perform the lifting movement;

[0061] Step 3: The downward movement of the cutter head 132 and then returning to the origin is a working cycle. When the cutter head 132 completes the downward movement and rises to the preset position, the in-position switch 160 is triggered. At this time, the rotating motor 1211 will stop rotating and continue to move upward under the drive of the lifting motor 1221. At this time, the cutter head 132 is also attracted by the magnetic part. When the cutter head 132 continues to rise, it will drive the fixed frame 142 to move upward as well. At this time, the stirring shaft 131 performs an upward and rotational movement with the cooperation of the first guide part 1421 and the second guide part 1412A, and drives the cutter head 132 to rotate under the action of the magnetic force. When the cutter head 132 rotates to a certain angle, the limiting boss 1321 on the cutter head 132 will separate from the limiting groove 1332 on the connecting head 133, completing the unlocking. This process completes the automatic retraction of the cutter, and finally the upward movement is stopped by triggering the upper limit switch 170.

[0062] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
