Description

Technical Field

[0001] The invention relates to the technical field of making smoothies, and in particular to a vertical smoothie machine and a use method thereof. Background Art

[0002] With the improvement of people's living standards and the acceleration of the pace of life, people have also put forward higher requirements for household electrical appliances. Generally speaking, miniaturized household electrical appliances are easy to carry and use, and can better meet the fast-paced life and work of modern people. Smoothie machines are equipment used to make smoothies, and have gradually become common electrical products. These devices generally use refrigeration cycle systems, and achieve refrigeration effects through components such as compressors, condensers, refrigeration heat exchangers, expanders or throttling mechanisms. At the same time, combined with a stirring mechanism, the ice-making liquid is cooled and stirred into a smoothie, and finally served to people through an outlet device.

[0003] The existing smoothie machines on the market can only make large-volume smoothies. When only a small amount of liquid is used to make smoothies, the evaporator is not fully utilized, resulting in excess power consumption. At the same time, large-volume smoothie production is suitable for commercial use but not for home use. In addition, the material barrel and evaporator of the current vertical smoothie machines on the market are integrated, which is not easy to wipe and clean, and is prone to hygiene problems; while the horizontal smoothie machine requires all the liquid or smoothie to be poured out before it can be disassembled and cleaned, which is cumbersome to operate.

[0004] The discharge mechanism of the existing ice smoothie machine barrel generally closes the discharge port of the barrel through a sealing ring or a cylindrical piston column. The cylindrical piston column is large in size, resulting in a large volume of the entire discharge mechanism. For example, a dual-purpose vertical snow melting machine disclosed in Chinese Patent No. ZL202410556858.X.

[0005] The existing vertical smoothie machine includes a scraper assembly mounted on the outside of the evaporator. The existing scraper assembly has only one working state. Therefore, when the user chooses to make a small amount of smoothie, since the scraper assembly has only one working state, it cannot adapt to making a small amount of smoothie. When there is only a small amount of liquid in the barrel, when making smoothie, the liquid is not in sufficient contact with the evaporator, and the evaporator will generate excess power consumption.

[0006] The scraper assembly structure of the existing vertical ice smoothie machine can refer to the dual-purpose vertical snow melting machine disclosed in Chinese Patent No. ZL202410556858.X, and the stirring assembly includes a first scraper member or a second scraper member drivingly connected to the drive motor, the material storage barrel and the evaporator are vertically arranged, and the first scraper member or the second scraper member is arranged in the material storage barrel and located on the outside of the evaporator.

When the smoothie is made, the material barrel can be lowered to a pending position through the lifting mechanism after the smoothie is output. The material barrel is separated from the evaporator, and the outer surface of the evaporator can be wiped and cleaned more conveniently.

[0015] The axial positioning movable matching part includes a positioning groove and a positioning rib block arranged between the inner scraper and the outer scraper; The inner scraper and the outer scraper are in a first initial matching state, and the positioning rib block is positioned on the positioning slot; A relative displacement occurs between the inner scraper and the outer scraper, a part of the positioning rib block is axially disengaged from the positioning slot, and the other part of the positioning rib block is always positioned in the positioning slot, and the inner scraper and the outer scraper are switched from a first initial matching state to a second matching state; when the inner scraper rotates, the outer scraper rotates with the inner scraper through the axial positioning movable matching part; The inner scraper is provided with a first scraper blade for scraping materials, the first scraper blade is arranged on the inner side of the inner scraper in an arc shape and is inclined, the first scraper blade is arranged on the inner side of the inner scraper by extending upward from the bottom position of the inner scraper, and the height of the position of one end of the first scraper close to the bottom of the inner scraper is lower than the height of the other end of the first scraper away from the bottom position of the inner scraper, so that when the inner scraper rotates, the first scraper blade forms a pushing part for pushing the material to make an axial upward movement; The bottom of the inner scraper is provided with a first notch communicating with the inner cavity of the inner scraper; The inner scraper is provided with a connecting piece for transmission connection with the stirring shaft, a connecting block is provided between the connecting piece and the inner scraper, and the connecting piece is positioned on the inner scraper through the connecting block; The outer scraper is provided with a second scraper blade for scraping materials, the second scraper blade is arranged at the inner bottom position of the outer scraper, the outer scraper is also provided with a positioning ring for positioning and installing on the inner cavity of the barrel, a third scraper blade is provided between the positioning ring and the outer scraper, the third scraper blade is arranged at the outer side of the bottom of the outer scraper, one end of the third scraper blade is connected to the positioning ring, and the other end of the third scraper blade is connected to the outer scraper; The bottom of the outer scraper is provided with a second notch communicating with the inner cavity of the outer scraper.

[0017] A method for using the vertical ice smoothie machine designed for this purpose comprises the following steps: Step 1: Assemble the scraper assembly on the inner cavity of the barrel; Step 2: The user starts the lifting mechanism according to the amount of smoothie production required, and the lifting mechanism raises the material barrel to the first lifting position or the second lifting position according to the user's operation instruction; Step 3: The stirring shaft rotates under the driving of the stirring motor, and the stirring shaft is connected with the inner scraper during the rotation; when the material barrel is in the second rising position, the material barrel has not reached the maximum rising position, and there is space between the inner scraper and the inner side of the body, the stirring shaft drives the scraper assembly to rotate through the threaded transmission connection, and the inner scraper moves upward along the outer scraper. The scraper assembly is in an open state during the working process, and the upper parts of the first cavity and the second cavity are connected to each other, so as to make a large volume of smoothies; The material barrel rises to the first rising position and reaches the maximum rising position. The stirring shaft is transmission-connected with the inner scraper during rotation. Since the inner scraper cannot move upward along the outer scraper, the scraper assembly is in a closed state during operation. The upper parts of the first cavity and the second cavity are not connected to each other, so as to make a small-capacity smoothie.

[0018] The beneficial technical effects of the present invention are as follows: The scraper assembly switches to a closed state or an open state through the cooperation between the inner scraper and the outer scraper. An axial positioning movable cooperation part is provided between the outer scraper and the inner scraper. The outer scraper and the inner scraper generate relative displacement through the axial positioning movable cooperation part. The scraper assembly switches from a closed state to an open state. The user can switch the working state of the scraper assembly according to the corresponding smoothie production amount to meet the user's needs of making a large or small amount of smoothies.

[0019] The first scraper blade on the inner side of the inner scraper is mainly used to scrape off the smoothie adhering to the evaporator. The first scraper blade pushes the liquid upward along the top of the evaporator to ensure that the liquid is in full contact with the evaporator. When there is only a small amount of liquid in the barrel, the liquid can also be in full contact with the evaporator, reducing the power consumption of the refrigeration system. During the rotation of the inner scraper, the liquid moves upward along the arc-shaped inclined first scraper blade to contact the evaporator, solving the problem of reduced efficiency in making smoothies due to insufficient contact between the liquid and the evaporator in the vertical smoothie machine, thereby increasing the power consumption of the evaporator, condenser and compressor.

[0020] The two second scraping blades and the third scraping blades at the bottom of the outer scraper are mainly used to push the smoothie smoothly to the discharge port of the material barrel.

[0021] The working state of the scraper assembly is switched by the moving position of the barrel, that is, the use state of the scraper assembly in the barrel is changed by adjusting the height of the lifting mechanism, thereby changing the amount of smoothie produced.

[0022] The material barrel and the scraper assembly can be directly disassembled and separated from the evaporator through the lifting mechanism, which makes wiping and cleaning more convenient. The scraper assembly is detachably installed on the inner cavity of the material barrel, which makes wiping and cleaning more convenient.

[0023] The material barrel is detachably mounted on the lifting end of the lifting mechanism through a connection structure (snap or threaded connection, etc.), making wiping and cleaning more convenient.

[0024] The discharging mechanism of the smoothie machine opens the discharging port of the material barrel through the cooperation of the handle and the baffle plate. The baffle plate seals the discharging port in the initial position. The baffle plate is small in size and can effectively replace the cylindrical piston column in the prior art. The production cost is low and the overall volume of the discharging mechanism is effectively reduced. The baffle plate can be driven to move in the direction of opening the discharging port by swinging the handle. The scraper assembly pushes the material in the material barrel to the outside of the discharging port during rotation.

[0025] When the lifting mechanism is lowered to a corresponding position, a plurality of lifting sleeves are in a stored and folded state. When the lifting mechanism is in a lowered state, the overall height of the lifting mechanism is small.

[0026] A plurality of lifting sleeves stacked up and down are used to assemble a lifting mechanism with a smaller space volume. The plurality of lifting sleeves stacked up and down perform lifting and telescopic actions to form a lifting mechanism with a larger sliding stroke. BRIEF DESCRIPTION OF THE DRAWINGS

In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, many specific details are set forth in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0048] See also Figure 1-Figure 19 A vertical smoothie machine includes a body 1, on which an evaporator 2 and a material barrel 3 are arranged, and the evaporator 2 and the material barrel 3 are arranged in an upper and lower divided manner. The body 1 is also provided with a lifting mechanism 4 for driving the material barrel 3 to move up and down, and the lifting end of the lifting mechanism 4 is connected to the material barrel 3, and the material barrel 3 is detachably installed on the lifting end of the lifting mechanism 4. The material barrel 3 is close to or away from the evaporator 2 through the lifting mechanism 4, and the material barrel 3 rises to a corresponding position height to cooperate with the evaporator 2 to make smoothies.

[0049] In this embodiment, an assembly cavity for installing a compressor 46 and a condenser 47 is provided in the machine body 1. The compressor 46, the condenser 47 and the evaporator 2 are connected to each other through pipes to form a closed loop for the circulation of refrigerant.

[0050] The material barrel 3 is driven to approach or move away from the evaporator 2 by the lifting mechanism 4. After the smoothie machine finishes its work, the material barrel 3 can be lowered by the lifting mechanism 4 and separated from the evaporator 2, which is convenient for wiping and cleaning the evaporator 2 of the smoothie machine. After the material barrel 3 is in the lowered state, the material barrel 3 can also be disassembled from the lifting mechanism 4, which is convenient for wiping and cleaning the material barrel 4. The material barrel 4 and the evaporator 2 can be directly disassembled and separated, and wiping and cleaning are more convenient.

[0051] The lifting mechanism 4 includes a plurality of lifting sleeves 5 stacked up and down, and the plurality of lifting sleeves 5 have a folded storage state and an unfolded and extended state; a plurality of protrusions 6 arranged at circumferential intervals are provided between two adjacent upper and lower lifting sleeves 5; during the ascending movement of the lifting mechanism 4, each lifting sleeve 5 performs an axial unfolding and extending movement along the corresponding protrusion 6; during the descending movement of the lifting mechanism 4, each lifting sleeve 5 performs an axial descending movement along the corresponding protrusion 6, and when the lifting mechanism 4 descends to the corresponding position, the plurality of lifting sleeves 5 are in a stored and folded state.

[0052] Each protrusion 6 of each lifting sleeve 5 is provided with an arcuate surface 7. Two arcuate surfaces 7 are provided, and the two arcuate surfaces 7 are symmetrically arranged on the protrusion 6. The two symmetrical arcuate surfaces 7 form an arcuate undulating guide portion to guide the corresponding lifting sleeve 5 to move up and down.

[0053] Each lifting sleeve 5 has multiple symmetrical convex surfaces (arc surfaces 7), and several lifting sleeves 5 are in contact with each other through the arc surfaces 7 to perform lifting activities. The groove 9 formed inside the protrusion 6 can accommodate the protrusion 6 of the next layer of lifting sleeve 5, so that when the lifting mechanism 4 is in the lowest position, there is only one lifting sleeve 5 at the height.

[0054] The odd-numbered lifting sleeves 5 and the even-numbered lifting sleeves 5 are respectively limited by the limiting slots 12 located in the middle lifting sleeve 1 to ensure that the heights of the two adjacent lifting sleeves 5 are the same. The lifting mechanism 4 is raised or lowered as a whole by rotating, which can be driven by the lifting motor 15. Steps can be provided on the contacting surfaces, and the lifting or lowering can be stopped at a predetermined rotation position and a predetermined height during the rotation process to meet the functional requirements of the equipment.

[0055] When the lifting sleeve 5 at the bottom of the lifting mechanism 4 is driven to rotate by the lifting motor 15, the lifting sleeve 5 at the bottom of the lifting mechanism 4 moves up and down along the lifting protrusion 14. Since several lifting sleeves 15 are provided with limit matching structures, the remaining lifting sleeves 5 will also follow the lifting sleeve 5 at the bottom of the lifting mechanism 4 to make rotational axial lifting movement through the limit matching structure.

When the motor shaft of the lifting motor 15 rotates, the lifting sleeve 5 at the bottom of the lifting mechanism moves up and down along the lifting protrusion 14; and when the lifting sleeve 5 at the bottom of the lifting mechanism descends to the corresponding position, the lifting protrusion 14 is received in the groove 5 of the lifting sleeve 5 at the bottom of the lifting mechanism.

[0057] In this embodiment, the ice smoothie machine is provided with a box body 66 for covering the fixing seat 13. The bottom surface of the fixing seat 13 can be used as the bottom cover of the box body 66. The box body 66 is provided with an opening corresponding to the lifting and telescopic part of the lifting mechanism 4. When the lifting mechanism 4 is lowered to the lowest height, the lifting mechanism 4 is stored in the box body 66.

[0058] The lifting sleeve 5 at the top of the lifting mechanism 4 is provided with a support 17 for supporting the barrel 3, and the barrel 3 is detachably mounted on the support 17; In this embodiment, a connecting column is provided on the support member 17, and a plug-in groove is provided on the lifting sleeve 5 at the top of the lifting mechanism 4.

[0060] In this embodiment, a mounting groove for accommodating an elastic clip 18 is provided on the support member 17, and a compression spring 65 is provided between the elastic clip 18 and the mounting groove. One end of the compression spring 65 elastically acts on the elastic clip 18, and the other end of the compression spring 65 elastically acts in the mounting groove.

[0061] In this embodiment, when the lifting mechanism 4 is raised, the elastic buckle 18 will clamp the material barrel 3 to prevent the material barrel 3 from falling out during lifting or working. When the lifting mechanism 4 is at the lowest point (the lifting mechanism 4 is reset to the initial state), the elastic buckle 18 will be pushed by the corresponding lifting sleeve 5 below, and the elastic buckle 18 is in a horizontal state and disengaged from the buckle hole 19. The compression spring 65 is close to the rotating end position of the elastic buckle 18. When the lifting mechanism 4 is reset to the initial state, the elastic buckle 18 abuts against the corresponding lifting sleeve 5 component, thereby compressing the compression spring 65.

The height of the position of one end of the first scraper blade 32 close to the bottom of the inner scraper 22 is lower than the height of the other end of the first scraper blade 32 away from the bottom of the inner scraper 22, so that when the inner scraper 22 rotates, the first scraper blade 32 forms a pushing part for pushing the material to make an axial upward movement. In this embodiment, a plurality of first scraping blades 32 are provided, and the plurality of first scraping blades 32 are arranged at intervals on the inner cavity of the inner scraper 22. The first scraping blades 32 are mainly used to scrape off the ice smoothie adhering to the evaporator 2, and the first scraping blades 32 push the liquid upward along the upper side of the evaporator 2 to ensure that the liquid is in full contact with the evaporator 2. When there is only a small amount of liquid in the barrel 3, the liquid can also be in full contact with the evaporator 2, thereby reducing the power consumption of the refrigeration system. During the rotation of the inner scraper 22, the liquid moves upward along the arc-shaped inclined first scraping blades 32 to contact the evaporator 2, thereby solving the problem that the efficiency of making ice smoothies in a vertical ice smoothie machine is reduced due to insufficient liquid level height, resulting in insufficient contact between the liquid and the evaporator 2, thereby increasing the power consumption of the evaporator 2, the condenser 47 and the compressor 46.

[0065] The bottom of the inner scraper 22 is provided with a first notch communicating with the inner cavity of the inner scraper 22; The inner scraper 22 is provided with a connecting piece 36 for transmission connection with the stirring shaft 25, and a connecting block 37 is provided between the connecting piece 36 and the inner scraper 22, and the connecting piece 36 is positioned on the inner scraper 22 through the connecting block 37; In this embodiment, three connection blocks 37 are provided, and the three connection blocks 37 are arranged at intervals.

[0066] In this embodiment, the entire inner scraper 22, the connecting block 37, the connecting member 36 and the first scraper blade 32 are formed into an inseparable whole by injection molding or metal processing.

[0067] In this embodiment, the connecting member 37 is used to connect the stirring shaft 25. A threaded shaft hole is provided in the connecting member 36, and the stirring shaft 25 is provided with an external thread corresponding to the threaded shaft hole.

[0070] A plurality of third scraping blades 35 are provided, and the plurality of third scraping blades 35 are arranged in an interval arrangement between the outer scraper 23 and the positioning ring 34 .

[0071] In this embodiment, the inner scraper 22 is a cylindrical structure, and the inner scraper 22 is mainly sleeved on the outer side of the evaporator 2. When the scraper assembly 21 is in an open state, the outer scraper 23 is in the inner cavity of the barrel 3, and the first cavity 38 between the barrel 3 and the outer scraper 23 is connected to the second cavity 39 between the inner scraper 22 and the evaporator 2, so that the production capacity range of the smoothie becomes larger, and a large amount of smoothie can be produced. When the scraper assembly 1 is in a closed state, the upper parts of the first cavity 38 and the second cavity 39 are not connected, and the production capacity range of the smoothie becomes smaller, so a small amount of smoothie can be produced.

[0072] In this embodiment, there is a height difference between the inner scraper 22 and the outer scraper 23 , and the height of the inner scraper 22 is greater than the height of the outer scraper 23 .

[0073] In this embodiment, the ice smoothie machine is provided with a limit ring 64 at the height of the outer side of the evaporator 2 and the rising position of the barrel 3. When the barrel 3 moves to the first rising position under the action of the lifting mechanism 4, the top of the barrel 3 abuts against the inner top wall of the limit ring 64, and the barrel 3 rises to the maximum stroke position.

Figure 3 As shown, the outer side of the barrel 3 abuts against the inner side wall of the limiting ring 64, and the stirring shaft 25 is inserted into the threaded shaft hole of the inner scraper 22 during the rotation. Since the stirring shaft 25 is in a fixed rotation state, the inner scraper 22 and the outer scraper 23 rotate along the stirring shaft 25, and the threaded shaft hole of the inner scraper 22 axially separates from the inner bottom wall of the barrel 3 along the stirring shaft 25, and the inner scraper 22 moves upward along the outer scraper 23, and the outer scraper 23 stays on the inner bottom wall of the barrel 3 under the action of gravity, and the top of the inner scraper 22 abuts against the inner top wall of the limiting ring 64, and a relative displacement occurs between the inner scraper 22 and the outer scraper 23, and a part of the positioning rib block 31 is relatively axially separated from the positioning slot 30, and the other part of the positioning rib block 31 is always positioned in the positioning slot 30, as shown in FIG.

The second connecting rod 55 moves between the first limit block 56 and the second limit block 57 as the handle 42 and the baffle plate 41 move.

[0085] In this embodiment, on the one hand, the first limit block 56 can limit the upper swing position of the second connecting rod 55, and on the other hand, the first limit block 56 can be used as a mounting block for fixing the bracket 52 on the bottom of the barrel 3.
