Description

Technical Field

[0001] This application relates to the field of food processing equipment technology, and in particular to a tiltable mixer. Background Technology

[0002] Currently, most countertop blenders on the market have both the blending jar and the main unit placed horizontally for blending, with the mixing components rotating 360 degrees at high speed in the center of the jar. However, when blending viscous foods such as frozen fruits, due to the high viscosity and poor flowability of these foods, a large amount of food easily adheres to the walls of the blending jar and cannot be evenly mixed. Since conventional blending jars cannot be moved, the food adhering to the jar walls is not tumbled finely enough by the blades and struggles to detach from the jar walls and enter the central mixing area. This results in the food not being truly thoroughly mixed, leading to a poor user experience.

[0003] It is evident that the existing tabletop blenders have the drawback of not being able to tilt and blend food adhering to the walls of the blending cup. There is an urgent need for a new type of blender that can tilt and swing the blending cup during the blending process, thereby allowing the food adhering to the cup wall to detach and rejoin the blending process. Summary of the Invention

[0004] The main objective of this application is to provide a tiltable mixer to solve the technical problem that existing countertop mixers cannot be tilted for mixing, resulting in uneven mixing of viscous food.

[0005] To achieve the above objectives, this application adopts the following technical solution: A tiltable mixer includes a mixing cup assembly, a locking base assembly, and a power assembly. The mixing cup assembly includes a mixing cup and a set of mixing blades. A horizontal mounting wall divides the mixing cup into an upper chamber and a lower chamber. The set of mixing blades is disposed inside the mixing cup. The locking base assembly includes an upper base and a universal drive shaft. The lower chamber of the mixing cup is connected to the upper base. The universal drive shaft is disposed inside the upper base, and its top is connected to the set of mixing blades. The bottom of the universal drive shaft is connected to the drive shaft of a first motor. The drive shaft carries... The stirring blade assembly is rotated; the upper base includes a rotating part, and the power assembly includes the first motor and the machine body; the first motor is provided with the motor drive shaft; the top of the machine body is provided with an arc-shaped groove, which corresponds to the rotating part of the upper base; the upper part of the universal drive shaft swings within the arc-shaped groove of the machine body along with the stirring cup and the upper base, for tilting the stirring cup; the upper base is provided with a movable limit buckle, which locks the position corresponding to the arc-shaped groove of the machine body, for limiting the upper base and the stirring cup from tilting and swinging back and forth along the same arc.

[0006] Preferably, the body is further provided with a latching assembly, which includes a latch, a button, and a spring; the latch is movably disposed within the body, and the spring is used to push the latch into the upper base and the body to lock the upper base; when the button is pressed, the latch compresses the spring and retracts from the upper base to unlock the upper base.

[0007] Through the coordinated operation of the universal drive shaft, arc groove, movable limit buckle, and pin locking assembly, the mixing cup can tilt and swing relative to the machine body during the mixing process. This allows viscous food adhering to the cup wall to detach from the cup wall under the action of gravity and inertia and be rolled back into the mixing area by the mixing blade assembly, thus achieving thorough and even mixing. At the same time, the pin locking assembly can lock and fix the mixing cup when tilting is not required, ensuring the stability of conventional horizontal mixing. It has both tilting and fixed mixing modes, significantly improving the mixing effect of viscous food and the user experience.

[0008] Preferably, the power assembly further includes a second motor, the output end of which is provided with a first helical tooth; the upper base is provided with an upper base meshing tooth, which meshes with the first helical tooth; the machine body is provided with an automatic swing switch; the automatic swing switch is electrically connected to the second motor.

[0009] Preferably, there are two movable limit buckles, symmetrically arranged on both sides of the rotating part, and the line connecting the two movable limit buckles is perpendicular to the direction of rotation of the upper part of the universal drive shaft.

[0010] Two symmetrically positioned movable limit buckles limit the rotation direction of the upper part of the universal drive shaft to be perpendicular to the line connecting them, so that the mixing cup can only tilt and swing back and forth along the same arc, rather than rotating without any dead angle. This ensures that the tilting direction is controllable, avoids excessive twisting of the mixing cup which could cause food to spill or the universal drive shaft to jam, and improves transmission reliability and safety of use.

[0011] Preferably, the latch assembly further includes a button holder; the button holder is fixedly disposed inside the body, the latch is disposed inside the button holder, the latch includes a cylindrical pin and a first rectangular groove, the first rectangular groove has a first inclined surface, and the bottom of the button has a corresponding second inclined surface; the spring is disposed between the first rectangular groove and the side wall of the button holder; the upper base has a first circular hole corresponding to the cylindrical pin, and the body has a corresponding second circular hole; when locked, the spring compresses the cylindrical pin to insert into the first circular hole and the second circular hole; when the button is pressed, the second inclined surface pushes the first inclined surface to disengage the cylindrical pin from the first circular hole and the second circular hole.

[0012] The pin locking assembly adopts a beveled surface fit and spring reset structure, realizing one-button unlocking and automatic spring locking, making operation simple and quick; when the mixing cup returns to the horizontal position, the cylindrical pin can automatically align and insert into the first and second round holes under the action of the spring to achieve automatic locking, preventing the mixing cup from tilting unexpectedly due to misoperation, thus improving safety and ease of operation.

[0013] Preferably, the central axes of the first circular hole, the second circular hole, and the cylindrical pin are not in the same horizontal plane as the lines connecting the two movable limiting buckles.

[0014] The central axis of the first circular hole, the second circular hole, and the cylindrical pin is not in the same horizontal plane as the line connecting the two movable limit buckles. This makes the locking direction of the pin lock and the swing limiting direction of the movable limit buckle spatially offset, avoiding motion interference between the two, ensuring locking reliability and swing smoothness, and improving the coordination and stability of the overall structure.

[0015] Preferably, the lower cavity inner wall of the stirring cup is detachably connected to the upper base via a stirring cup latch, and a limit slot is provided on the lower cavity inner wall of the stirring cup corresponding to the position of the stirring cup latch.

[0016] The mixing cup locking buckle and the limiting slot work together to achieve a quick and detachable connection between the mixing cup and the upper base, making it easy for users to disassemble the mixing cup for cleaning and replacement, thus improving ease of use and hygiene safety.

[0017] Preferably, the mixing cup assembly further includes a lid, and the lid and the mixing cup are detachably connected.

[0018] The lid is detachably connected to the mixing cup, which effectively prevents food from splashing out during mixing, and also makes it easy for users to add ingredients midway, improving the flexibility of use and cleanliness.

[0019] Preferably, the stirring blade assembly includes a blade, an upper stirring part, and a lower stirring part, which are connected in sequence. The diameter of the upper stirring part is smaller than that of the lower stirring part. A first circular groove is provided at the center of the horizontal mounting wall, with the opening of the first circular groove facing downward. A first bearing is provided inside the first circular groove. The blade is located above the first circular groove. The upper stirring part passes through the central circular hole at the top of the first circular groove, the central hole of the first bearing, and the central hole of the sealing limiting piece in sequence. A retaining spring is provided outside the connection between the upper stirring part and the lower stirring part. The retaining spring is arranged around the connection and is limited by the sealing limiting piece, which seals the opening of the first circular groove.

[0020] The first bearing and the snap ring, together with the sealing and limiting plate, achieve stable rotational support and dynamic sealing of the stirring blade assembly, preventing liquid in the stirring cup from leaking downwards from the first circular groove. At the same time, the snap ring limiting structure facilitates the disassembly and maintenance of the stirring blade assembly, improving transmission reliability and sealing performance.

[0021] Preferably, the upper part of the universal drive shaft is provided with a first mounting groove, and the lower part of the agitator is sleeved in the first mounting groove.

[0022] The lower part of the agitator is fitted into the first mounting groove of the universal drive shaft, realizing a detachable transmission connection between the agitator blade assembly and the universal drive shaft. This facilitates user disassembly, cleaning, and replacement of the agitator blade assembly, improving maintenance convenience.

[0023] Preferably, the upper base further includes a cylindrical portion, which is integrally formed with the rotating portion; the cylindrical portion opens upward, and a horizontal mounting plate is provided between the cylindrical portion and the rotating portion; a protrusion is provided at the center of the horizontal mounting plate, and a second circular groove is provided at the center of the protrusion; the second circular groove opens upward, and a second bearing is provided inside the second circular groove; the upper part of the universal drive shaft passes sequentially through the central circular hole of the bottom wall of the second circular groove, the central hole of the second bearing, and the central hole of the sealing limiting plate; the upper part of the universal drive shaft rotates with the stirring cup and the upper base.

[0024] The second bearing and the sealing limit plate work together to achieve flexible rotation support and sealing between the universal drive shaft and the upper base. This ensures that the universal drive shaft can still rotate smoothly and stably relative to the upper base when the stirring cup is tilted, while preventing liquid from seeping into the interior of the upper base, thus improving transmission flexibility and internal protection performance.

[0025] Preferably, the lower part of the universal drive shaft is located in the inner cavity of the rotating part, and the lower part of the universal drive shaft is provided with a second mounting groove with an opening facing downward, the second mounting groove being connected to the motor drive shaft.

[0026] The second mounting slot connects to the motor drive shaft, enabling a detachable transmission connection between the universal drive shaft and the first motor, which facilitates the assembly, disassembly, and maintenance of the entire machine.

[0027] Preferably, the power assembly further includes a lower base for mounting the first motor, and the bottom of the lower base is provided with rubber feet.

[0028] The lower base and rubber feet provide stable support and cushioning, effectively reducing vibration and noise during mixer operation, and improving the overall stability and user comfort.

[0029] Preferably, the machine body is provided with a rotary switch for controlling the rotation or stopping of the motor drive shaft.

[0030] The rotary switch allows users to intuitively and conveniently control the start and stop of the first motor, simplifying operation and improving the convenience of human-machine interaction.

[0031] This application has the following beneficial effects: This application utilizes the coordinated operation of a universal drive shaft, an arc-shaped groove, a movable limit buckle, and a pin locking assembly to allow the mixing cup to tilt and swing back and forth along a fixed arc relative to the machine body during the mixing process. When mixing viscous foods such as frozen fruits, the food adhering to the cup wall can detach from the cup wall under the action of gravity and inertia, and be re-rolled into the central mixing area by the mixing blade assembly. This effectively solves the technical problem of uneven mixing of food on the cup wall caused by the inability of existing countertop blenders to tilt and mix, significantly improving the smoothness of the mixture and the user's eating experience.

[0040] Example 1 refer to Figures 1 to 8 This application provides a tiltable mixer, including a mixing cup assembly, a locking base assembly, and a power assembly.

[0041] The mixing cup assembly includes a lid 1, a mixing cup 5, and a blade assembly 2. The lid 1 and the mixing cup 5 are detachably connected.

A retaining spring 4 is provided outside the connection between the upper stirring part 25 and the lower stirring part 26. The retaining spring 4 is arranged around the connection and is limited by the sealing limiting piece 37, which seals the opening of the first circular groove 27. The upper end of the lower stirring part 26 abuts against the lower part of the retaining spring 4. The first bearing 3 provides rotational support for the stirring blade assembly 2. The sealing and limiting plate 37 and the snap ring 4 work together to achieve dynamic sealing and axial limiting, preventing the liquid in the stirring cup 5 from leaking downwards along the upper stirring part 25.

[0043] The locking base assembly includes an upper base 8 and a universal drive shaft 7. The upper base 8 includes a cylindrical part 30 and a rotating part 31, which are integrally formed. The cylindrical part 30 has an upward opening, and the lower cavity 21 of the stirring cup 5 is fitted onto the outer wall of the cylindrical part 30. An L-shaped stirring cup latch 9 is provided on the outer wall of the cylindrical part 30, and a limiting groove is provided on the inner wall of the lower cavity 21 of the stirring cup 5 corresponding to the position of the stirring cup latch 9. The stirring cup latch 9 and the limiting groove are mature technologies in related fields and will not be described in detail here. The inner wall of the lower cavity 21 of the stirring cup 5 is fitted onto the outer wall of the cylindrical part 30, and the bottom surface of the horizontal mounting wall 19 abuts against the top of the cylindrical part 30. The stirring cup latch 9 and the limiting groove cooperate to achieve a detachable and fixed connection between the stirring cup 5 and the upper base 8.

[0044] A horizontal mounting plate 33 is provided between the cylindrical part 30 and the rotating part 31. A protrusion 34 is located at the center of the horizontal mounting plate 33, and a second circular groove 35 is located at the center of the protrusion 34. The second circular groove 35 opens upwards, and a second bearing 6 is installed inside the second circular groove 35. Multiple second ball bearings are evenly arranged inside the second bearing 6. The upper part of the universal drive shaft 7 passes sequentially through the central circular hole in the bottom wall of the second circular groove 35, the central hole of the second bearing 6, and the central hole of the sealing and limiting plate 36. A first mounting groove 28 is provided on the upper part of the universal drive shaft 7, and the lower stirring part 26 is fitted into the first mounting groove 28. The upper part of the universal drive shaft 7 rotates with the stirring cup 5 and the upper base 8. The second bearing 6 provides rotational support for the universal drive shaft 7, and the sealing and limiting plate 36 seals the second circular groove 35 to prevent liquid from entering the interior of the upper base 8.

[0045] The lower part of the universal drive shaft 7 is located in the inner cavity of the rotating part 31. The lower part of the universal drive shaft 7 is provided with a second mounting groove 29 with an opening facing downward. The second mounting groove 29 is connected to the motor drive shaft 22 of the first motor 16. The motor drive shaft 22 drives the universal drive shaft 7 to rotate, thereby driving the stirring blade assembly 2 to rotate.

[0046] The rotating part 31 of the upper base 8 is shaped like an inverted hill, approximately "W". The rotating part 31 is formed by a first opening 311 at the bottom of the hemispherical base, which consists of four arc-shaped sides, symmetrically arranged in pairs. The arc-shaped groove 23 at the top of the body 14 is a hemispherical groove, and the outer wall of the rotating part 31 of the upper base 8 fits against the inner wall of the arc-shaped groove 23. The upper part of the universal drive shaft 7 swings within the arc-shaped groove 23 of the body 14 as the mixing cup 5 and the upper base 8 move, thus tilting the mixing cup 5.

[0047] The rotating part 31 of the upper base 8 has two hills on either side symmetrically arranged with outwardly extending movable limit buckles 10. The movable limit buckles 10 engage with the corresponding positions of the arc-shaped groove 23 of the body 14. The engagement of the movable limit buckles 10 with the body 14 is a mature technology in related fields and will not be elaborated here. The rotation direction of the upper part of the universal drive shaft 7 is perpendicular to the line connecting the two movable limit buckles 10. The two movable limit buckles 10 limit the upper base 8 and the mixing cup 5. The upper base 8 and the mixing cup 5 do not tilt and rotate 360 ​​degrees without dead angles, but tilt and swing back and forth along the same arc line to ensure that the tilt direction is controllable and avoid excessive twisting.

[0048] A pin locking assembly is provided inside the outer wall of the rotating part 31 and the body 14. The pin locking assembly includes a pin lock 12, a button 11, a button fixing seat 13, and a spring 38. The button fixing seat 13 is fixedly installed inside the body 14. The button fixing seat 13 is a rectangular groove with one side without a sidewall, the opening facing upward, and the side without a sidewall is attached to the outer wall of the arc-shaped groove 23 of the body 14.

[0049] The latch 12 is disposed within the button mounting base 13. The latch 12 comprises two parts: an integrally formed cylindrical latch 12a and a first rectangular groove 43. The first rectangular groove 43 opens upward and has a first inclined surface 39. The bottom of the button 11 has a second inclined surface 40 corresponding to the first inclined surface 39, and the top of the body 14 has a button groove. The upper base 8 has a first circular hole 41 corresponding to the cylindrical latch 12a, and the body 14 has a second circular hole 42 corresponding to the cylindrical latch 12a. A spring 38 is connected to the end of the first rectangular groove 43 away from the cylindrical latch 12a, and the spring 38 is disposed between the first rectangular groove 43 and the side wall of the button mounting base 13. The central axis of the first circular hole 41, the second circular hole 42, and the cylindrical latch 12a are not on the same horizontal plane as the line connecting the two movable limit buckles 10, to avoid motion interference between the latch assembly and the movable limit buckles 10.

[0050] When locked, spring 38 compresses cylindrical pin 12a, inserting it into the first round hole 41 and the second round hole 42, and the upper base 8 and the mixing cup 5 no longer swing relative to the body 14. Pressing button 11 downward in the button slot causes the second inclined surface 40 to push the first inclined surface 39 outward, and the second inclined surface 40 inserts into the clearance groove at the bottom of the first rectangular groove 43; at the same time, spring 38 is compressed, and cylindrical pin 12a exits the first round hole 41 and the second round hole 42, allowing the upper base 8 and the mixing cup 5 to swing relative to the body 14.

[0051] The power assembly includes a first motor 16 and a body 14. The first motor 16 is equipped with a motor drive shaft 22. The body 14 is also equipped with a lower base 17 for mounting the first motor 16, and rubber feet 18 are respectively provided at the four corners of the bottom of the lower base 17. A rotary switch 15 is provided on the body 14 for controlling the rotation of the motor drive shaft 22 to operate or stop.

[0052] The working principle of this application embodiment is as follows: First, place the mixing cup assembly on the upper base 8 and secure it with the mixing cup locking buckle 9. Connect the lower mixing part 26 of the mixing blade assembly 2 to the first mounting groove 28 of the universal drive shaft 7. Place food into the mixing cup 5 and close the lid 1. Turn on the knob switch 15; the first motor 16 starts, and the motor drive shaft 22 drives the mixing blade assembly 2 through the universal drive shaft 7 to perform mixing. Figure 4 As shown, the stirring cup 5 is in a horizontally locked state, the cylindrical pin 12a is inserted into the first round hole 41 and the second round hole 42, the upper base 8 and the stirring cup 5 are fixed in place, and conventional horizontal stirring is performed.

[0053] When blending viscous foods such as frozen fruit, causing food to stick to the walls of the blender cup 5, press button 11 to trigger the latch locking assembly to unlock. Figure 5 As shown, the second inclined plane 40 pushes the first inclined plane 39 outward, compressing the spring 38, and the cylindrical pin 12a disengages from the first circular hole 41 and the second circular hole 42. At this time, the user can hold the mixing cup handle and move it back and forth, as shown. Figure 6 As shown, under the limiting action of the movable limit buckle 10, the upper base 8 and the mixing cup 5 tilt and swing back and forth along the same arc. The upper part of the universal drive shaft 7 swings accordingly and continuously transmits torque. The mixing blade assembly 2 rotates in the tilted state, scraping off the food adhering to the cup wall and re-rolling it into the mixing area, thus achieving thorough mixing by tilting.

[0054] When the mixing cup 5 returns to the horizontal position, the first round hole 41 and the second round hole 42 are realigned, and the cylindrical pin 12a is automatically inserted into the first round hole 41 and the second round hole 42 under the elastic force of the spring 38. The upper base 8 and the mixing cup 5 are automatically locked and fixed, and normal horizontal mixing can be restored.

[0055] Example 2 Reference Figures 8 to 12 The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the user manually rotates the stirring cup. However, this embodiment no longer includes the latch locking assembly and button 11, but adds a second motor 100 and a first helical gear 101 for mechanical movement to achieve an automatic oscillation function.

[0056] Preferably, the power assembly further includes two second motors 100 respectively disposed on the outer sides of two movable limit buckles 10 inside the body 14, and each of the second motors 100 has a first helical tooth 101 at its output end; preferably, in this embodiment, the second motor 100 is a stepper motor or a servo motor. The upper base 8 has an upper base meshing tooth 102 corresponding to the position of the first helical tooth 101, which meshes with the first helical tooth 101. The upper base meshing tooth 102 is elongated arc-shaped. When the second motor 100 drives the first helical tooth 101 to rotate, the upper base meshing tooth 102, in coordination with the rotation direction of the second motor 100, drives the upper base 8 to rotate. Two movable limit buckles 10 are disposed on both sides of the first opening 311, respectively fastening the limit seats 231 at the corresponding positions of the arc-shaped groove 23. The limit seats 231 are elongated arc-shaped, and baffles 232 are provided at both ends of the limit seats 231. A limiting plate 300 is provided between the two movable limiting buckles 10. The limiting plate 300 has folded edges on both sides facing the movable limiting buckles 10. The limiting plate 300 restricts the movable limiting buckles 10 between the limiting plate 300 and the limiting seat 231. When the upper base 8 rotates, the movable limiting buckles 10 rotate along the arc of the limiting seat 231.

[0057] The machine body 14 is equipped with an automatic swing switch 103; the automatic swing switch 103 is electrically connected to the PCB board and the second motor 100.

[0058] When the user turns on the automatic rocking switch 103, the automatic rocking switch 103 is powered on, and the second motor 100 is driven by the PCB board to realize the automatic mechanical rocking function. The movable limit buckle 10 works in conjunction to limit the movement. The second motor 100 performs the rocking movement by meshing the first helical tooth 101 with the upper base meshing tooth 102.

[0059] In summary, this application achieves controllable tilting and oscillation of the mixing cup 5 during the mixing process through the coordinated cooperation of the universal drive shaft 7, the arc groove 23, the movable limit buckle 10, and the pin locking assembly or the engagement of the first helical tooth 101 and the upper base meshing tooth 102. This effectively solves the technical problem of viscous food sticking to the cup wall and uneven mixing. At the same time, the pin locking assembly enables one-button unlocking and automatic locking, making the operation convenient, safe and reliable.
