Description

Technical Field

[0001] This invention relates to the field of electric conditioner technology, and more specifically to a rotationally stable electric conditioner. Background Technology

[0002] As people's living standards improve, the types and functions of household appliances are becoming increasingly diverse. Among them, electric blenders are a common household appliance, widely used in homes, restaurants, cafes and other places for shaking milk, mixing beverages and so on.

[0003] Because of the significant difference in specific gravity between powdered solutions and water, many powdered solutions dissolve slowly. Slow shaking often fails to achieve rapid, complete, and uniform mixing, and can cause powder particles to clump together, forming large clumps. To address this, commercially available blenders typically use high-speed motors as the drive source. High-speed motors improve the efficiency of dissolving the powder in water, allowing for thorough mixing in a short time. However, the use of high-speed motors can also cause mechanical vibrations due to unbalanced centrifugal force as the motor drives the solvent. This can lead to resonance of the casing, generating noise and causing the equipment to shake violently, easily causing the container to tip over, thus affecting the user experience.

[0004] To address these issues, several vibration and noise reduction technologies have been applied to electric conditioners. For example, rubber feet are installed at the bottom of the device, and sound-absorbing materials are filled around the motor to reduce the transmission of vibration and noise. However, these traditional methods often only alleviate vibration problems to a certain extent and cannot fundamentally solve the impact of mechanical vibration on the stability of the equipment.

[0005] Therefore, there is an urgent need to design a rotating and stable electric conditioner to solve the problems of high equipment noise, poor vibration isolation effect and unstable operating conditions caused by high-speed motor rotation. Summary of the Invention

[0006] This application provides a rotationally stable electric conditioner, which aims to solve the problems of high equipment noise, poor vibration isolation effect and unstable operating conditions when the electric conditioner is working.

[0007] To achieve the above objectives, this application adopts the following technical solution: a rotationally stable electric conditioner, comprising a housing and a rotating device, the rotating device comprising a mounting plate, a rotating component rotatably engaged on the mounting plate, and a motor fixedly connected to the mounting plate, the rotating component being drivenly connected to the motor;

[0008] The mounting plate is attached to the housing by at least one multi-vibration damping mechanism, which is adapted to reduce mechanical vibrations generated by the rotating device and prevent them from being transmitted to the housing.

[0009] The multiple vibration damping mechanisms include:

[0010] An elastic damping system includes at least one spring clamped between a mounting plate and a housing, the elastic damping system supporting the mounting plate as a multi-degree-of-freedom floating structure; and

[0011] An energy-dissipating damping system includes at least one set of mutually adapted damping rods and dampers. In response to a multi-degree-of-freedom floating event of the mounting plate, relative movement occurs between the damping rods and dampers, generating a damping force that opposes the relative movement. The damping rods are attached to one of the mounting plate and the housing, and the dampers are attached to the other.

[0012] Furthermore, multi-degree-of-freedom floating events include the left-right swaying and up-down bouncing of the mounting plate.

[0013] Furthermore, the elastic damping system includes three springs, which are evenly distributed around the mounting plate.

[0014] Furthermore, in response to the multi-degree-of-freedom floating events of the mounting plate, the elastic damping system absorbs the mechanical vibrations generated by the mounting plate through compression or elongation.

[0015] Furthermore, the damping rod is attached to the mounting plate, the damper is attached to the housing, and the damper is fitted onto the damping rod to generate damping force.

[0016] Furthermore, the damping rod is configured to produce elastic bending deformation to accommodate the lateral swaying of the mounting plate.

[0017] Furthermore, the damping rod is configured as a long plastic rod suitable for producing elastic bending deformation.

[0018] Furthermore, the damper is a grease damper or a friction damper.

[0019] Furthermore, the damper is a rubber sleeve fixed to the housing.

[0020] Furthermore, the energy-dissipating damping system includes three sets of mutually compatible damping rods and damping sleeves, which are evenly distributed around the mounting plate.

[0021] Furthermore, the electric blender involved in this application is one of a milk shaker and a beverage blender.

[0022] The beneficial effects of this invention are as follows: By designing a multi-stage vibration damping mechanism, the vibration damping performance and operational stability of the equipment are improved. Specifically, the rotating device is connected to the elastic vibration damping system in a multi-degree-of-freedom floating manner, allowing the elastic vibration damping system to effectively isolate and reduce the mechanical vibration generated by the rotating device, making the equipment more stable during operation. Furthermore, by setting up an energy-dissipating damping system, multiple sets of mutually compatible damping rods and rubber damping sleeves are used to convert vibration into damping force and friction, thereby further eliminating the mechanical vibration of the equipment. The multi-stage vibration damping mechanism can reduce mechanical vibration and prevent its transmission to the housing, providing excellent vibration isolation for the housing, thereby reducing the resonance and shaking of the housing, reducing the operating noise of the equipment, significantly improving the operational stability of the equipment, and enhancing the user experience.

[0034] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0035] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0036] Example 1:

[0037] like Figure 1-4 As shown, this embodiment provides a rotationally stable electric conditioner, including a housing 10 and a rotating device 20, which drives the rotating component 22 to rotate at high speed.

[0038] The rotating device 20 includes a mounting plate 21, a rotating component 22, and a motor 23. The rotating component 22 is rotatably engaged with the mounting plate 21 and is drively connected to the motor 23, which drives it to rotate. The motor 23 is fixed to the mounting plate 21 and provides rotational power to the rotating component 22.

[0039] Specifically, taking a milk shaker as an example, the rotating component 22 is the milk shaker frame. In order to ensure that the milk shaker frame can stably hold the milk bottle or the bottle containing the powder, a claw 24 that can apply force to the bottle is provided on the circumferential side of the inner wall of the milk shaker frame. Furthermore, in order to ensure that the claw can apply force evenly on the circumferential side of the milk bottle, three or four sets of claws 24 can be evenly arranged along the inner ring end wall of the milk shaker frame.

[0040] In a preferred embodiment, the gripper 24 can also be hinged to the inner wall of the shaker frame via a shaft connection, and then held between the gripper 24 and the side wall of the shaker frame by a compression spring 25, so as to effectively hold the bottle. Furthermore, to better hold the bottle, the gripper 24 is configured in two layers. This layered design allows pressure to be applied to the upper and lower ends of the shaker frame when the bottle is placed inside, thus stably clamping the bottle within the frame. This prevents the bottle from wobbling irregularly in the shaker frame due to unbalanced centrifugal force caused by the high-speed rotation of the motor 23 shaking the bottle and its liquid, further improving the stability of the equipment during operation.

[0041] When using an electric blender to shake and mix powdered baby formula, many powdered formulas (such as sesame paste, soy milk powder, and other paste-like powders) dissolve slowly. Slow shaking with a blender often fails to achieve a quick and even mixing with water. Furthermore, when the blender's motor speed is too slow, it can cause powder particles to clump together, forming large clumps. This results in the powder sticking to the inside of the bottle and container, increasing the difficulty of cleaning the bottle and wasting the powder.

[0042] Therefore, a high-speed motor is selected in the product design, increasing the set speed of the shaking frame to 1000 rpm or even 1500 rpm. Compared to traditional milk shakers (where the shaking frame speed is only around 500 rpm), this can reduce the shaking time by half or even more, making it more time-saving and labor-saving for users when mixing formula. Taking the milk shaker as an example, the uniform mixing effect brought by the high speed ensures the quality of the milk and formula, protects the baby's delicate digestive system, and reduces gastrointestinal problems caused by uneven dissolution.

[0043] As an optional implementation, the rotating component 22 (milk shaker frame) can be directly connected to the motor shaft of the motor 23. When the milk shaker frame is directly connected to the motor shaft of the motor 23, the axis of the milk shaker frame should be collinear with the axis of the motor shaft to avoid excessive centrifugal force caused by the imbalance of its center of gravity during the rotation of the milk shaker frame, which would exacerbate the shaking of the equipment. Similarly, in order to reduce the internal space of the milk shaker and make its structure more compact, the motor 23 and the milk shaker frame can be arranged on both sides. When the axis of the motor shaft and the axis of the milk shaker frame are not collinear, gear transmission or belt transmission can be used to ensure that the motor 23 can efficiently drive the milk shaker frame to rotate at high speed.

[0044] Furthermore, to reduce the size of the milk shaker and make it easier to store and carry, the internal structure of the milk shaker has been optimized. Specifically, a direct drive method is adopted where the motor 23 is directly connected to the rotating component 22 (milk shaking frame). The rotating component 22 is coaxially connected to one side of the motor shaft, thus ensuring that there is no transmission between the two through other mechanical structures, thereby improving the driving efficiency of the motor. A vertically open mounting hole is opened in the middle of the mounting plate 21, and the motor 23 passes through the mounting hole from bottom to top and is then fixed to the mounting plate 21 with fasteners (such as screws, bolts, etc.). This design not only reduces the size of the rotating device 20, but also makes the layout of the entire device more compact and reasonable.

[0045] In traditional milk shakers, the rotating device 20 directly abuts against the housing 10, or an elastic insulating pad, such as a silicone pad or a rubber pad, is added between them to prevent or reduce the mechanical vibration generated when the rotating device 20 is working. Other methods include adding sound-absorbing cotton inside the housing 10 or adding a rubber pad to the bottom of the housing 10 to reduce equipment shaking caused by these mechanical vibrations. However, these measures have limited vibration reduction effects, and stable operation of the equipment cannot be guaranteed even when the set speed of the motor 23 is high.

[0046] When the rotating component 22 holds the baby bottle and rotates at high speed under the power of the motor 23, mechanical vibration will inevitably be generated. The noise and shaking of the conditioning equipment during operation are mainly caused by the resonance of the housing 10 due to the mechanical vibration transmitted to it. In order to isolate this mechanical vibration and prevent it from being transmitted to the housing 10 and causing the equipment to shake, a multi-vibration damping mechanism 30 is added between the mounting plate 21 and the housing 10.

[0047] Specifically, the multiple vibration damping mechanism 30 is configured as two parts: a set of elastic vibration damping system 41 and a set of energy dissipation damping system 51.

[0048] The elastic vibration damping system 41 includes at least one spring 42, preferably three springs 42, located at the three vertices of the mounting plate 21 (or a suitable layout can be selected according to actual needs), and installed between the mounting plate 21 and the housing 10. The stiffness and number of springs 42 can be adjusted according to factors such as the weight of the equipment and the vibration frequency to ensure that when the mounting plate 21 is subjected to mechanical vibration, the springs 42 can effectively absorb and reduce vibration energy, so that the mounting plate 21 maintains a relatively stable floating state.

[0049] In the elastic vibration damping system 41, springs 42 are used between the housing 10 and the mounting plate 21 to initially reduce the mechanical vibration generated by the rotating device 20. Furthermore, by employing three sets of springs 42, the rotating device 20 can be supported, allowing it to float and suspend above the housing 10. That is, the rotating device 20 floats freely above the housing 10. When the motor 23 is started, the rotating device 20 generates mechanical vibration in a floating manner. This free floating includes movement in the horizontal direction and movement in the vertical direction.

[0050] The use of multiple sets of springs 42 is to distribute the total mass of the rotating device 20 and the bottle held on it evenly to each set of springs 42. The three sets of springs 42 are evenly arranged on the housing 10 in a circular manner. The circular layout can further ensure that the elastic damping system 41 can play a better damping role when the rotating device 20 is working.

[0051] As a preferred embodiment, a cylindrical helical spring is preferably used for spring 42. Cylindrical helical springs have stronger deformation performance, longer service life, and lower procurement costs. They are also readily available on the market, facilitating product maintenance. Furthermore, cylindrical helical springs have better load-bearing capacity than conical and disc springs, making them more suitable for supporting the weight of the rotating device 20 and the load of the container clamped in the rotating component 22. This ensures that when the mounting plate 21 is subjected to mechanical vibration, the spring 42 can effectively absorb and reduce vibration energy, allowing the mounting plate 21 to maintain a relatively stable floating state during operation.

[0052] Depend on Figures 3 to 5 Furthermore, the energy-dissipating damping system 51 is configured to respond to multi-degree-of-freedom floating events of the mounting plate 21 (i.e., the rotating device 20 floats freely above the housing 10 via three sets of mutually adapted damping rods 52 and dampers 53). When the energy-dissipating damping system 51 is subjected to mechanical vibrations transmitted by the motor 23, relative movement occurs between the damping rods 52 and dampers 53, thereby generating a damping force that opposes this relative movement. The damping rods 52 are attached to either the mounting plate 21 or the housing 10, and the dampers are attached to the other.

[0053] In a preferred embodiment, the damping rod 52 is attached to the mounting plate 21 and designed to undergo elastic bending deformation. This bending deformation ensures that it can follow and adapt to the left-right swaying of the mounting plate 21 during operation. Additionally, a damper 53 is attached to the housing 10, fitting over the damping rod 52. Both generate damping force through the adhesion or friction of the damping material (such as rubber, grease, etc.).

[0054] When the mounting plate 21 floats with multiple degrees of freedom, relative movement occurs between the damping rod 52 and the damper 53. The damper 53 impedes the movement of the damping rod 52, thereby dissipating vibration energy. Similar to the elastic vibration reduction system 41, the energy-dissipating damping system 51 is also arranged in a circumferential manner, with three sets evenly distributed between the housing 10 and the mounting plate 21.

[0055] Furthermore, the damping rod 52 is configured as a long plastic rod capable of fully elastic deformation to accommodate vibrations in different directions. The damper 53 can be a grease damper, a friction damper, or a rubber sleeve fixed to the housing 10, etc. In this embodiment, the damper 53 is preferably a rubber sleeve with good damping effect and readily available on the market.

[0056] When designing a product, the appropriate type of damper should be selected according to actual needs. For example, when the power of the motor 23 is very high, a damping rod with better bending deformation performance and a friction damper with better damping effect should be selected accordingly. Preferably, the energy-dissipating damping system 51 is configured with a plastic rod and a silicone sleeve with deformation capability. This is not only because the silicone sleeve and plastic rod are inexpensive and have good bending deformation performance, but also because when the plastic rod rubs against the silicone sleeve, the plastic rod itself can also bear a portion of the load from the rotating device 20, thereby further increasing the stability of the equipment.

[0057] Furthermore, to prevent the entire conditioner from moving on the tabletop due to resonance of the housing 10, vibration damping feet 60 are installed on the lower end face of the housing 10, thereby further reducing the transmission of vibration to the bottom of the device and the surrounding environment. The vibration damping feet 60 can be made of elastic materials such as rubber or silicone, which absorb and disperse vibration energy to reduce the impact of vibration on the device.

[0058] Furthermore, to further reduce noise, sound-insulating materials such as foam or sponge can be placed around the motor 23 to reduce the noise generated during motor operation from interfering with the user. The sound-insulating materials can be customized according to the shape and size of the motor to ensure that they can effectively cover the motor and reduce the transmission of noise.

[0059] Furthermore, to improve the stability of the rotating component 22 during rotation, a balance block can be installed on the rotating component 22 of the rotating device 20 to adjust the center of gravity of the rotating component 22, making it more stable during operation. The balance block can be designed and adjusted according to the shape and mass distribution of the rotating component 22 to ensure that it can effectively improve the stability of the equipment.

[0060] Example 2:

[0061] As another alternative implementation, electromagnetic dampers and rubber dampers are two common vibration control devices. When the granules to be mixed have a high viscosity and are difficult to dissolve in water in a short time, a high-power motor is selected for motor 23 to accelerate the dissolution efficiency. This motor will generate stronger mechanical vibrations when rotating, and the equipment needs better vibration isolation to prevent mechanical resonance of the housing 10. Accordingly, the energy-dissipating damping system 51 selects an elastic plastic rod with better bending performance and an electromagnetic damper with better damping effect.

[0062] However, a detailed comparison reveals that the electromagnetic damper exhibits significant advantages in multiple dimensions. The following is an in-depth analysis of the advantages of the electromagnetic damper compared to the friction damper in Example 1.

[0063] First, from the perspective of energy consumption and environmental friendliness, electromagnetic dampers utilize the principle of electromagnetic induction to generate the required damping force by controlling the current in a coil. This process is relatively energy-efficient and environmentally friendly. In contrast, rubber dampers rely on the physical deformation of rubber materials to dissipate energy. While this mechanism is simple and effective, it may lead to aging and wear of the rubber materials during long-term use, thereby increasing replacement and maintenance costs. More importantly, the production and processing of rubber materials may have adverse environmental impacts, while electromagnetic dampers demonstrate greater sustainability in this regard.

[0064] Secondly, electromagnetic dampers offer greater flexibility and controllability in terms of performance. By precisely adjusting the magnitude and direction of the current in the coil, the damping force can be accurately controlled, thus meeting the vibration control requirements under different operating conditions. In contrast, the performance of rubber-based friction dampers is relatively fixed and difficult to adjust flexibly according to actual needs, which to some extent limits their application range.

[0065] Furthermore, electromagnetic dampers also excel in terms of service life and reliability. Because their operating principle does not involve physical deformation, the wear and tear on their internal components is relatively low, thus extending the equipment's lifespan. In addition, electromagnetic dampers have a relatively simple structure, making them easy to maintain and repair, further enhancing their reliability. In contrast, rubber dampers may experience performance degradation due to aging and wear during long-term use, requiring regular replacement and maintenance, which increases operating costs.

[0066] Furthermore, electromagnetic dampers offer advantages such as high adaptability and fast response. They can quickly respond to vibration signals and generate corresponding damping forces, effectively suppressing vibration. This characteristic makes electromagnetic dampers particularly advantageous in applications requiring rapid response to conditioner mechanical vibrations. Simultaneously, electromagnetic dampers can adapt to vibration signals of different frequencies and amplitudes, exhibiting stronger adaptability and stability.

[0067] Specifically, electromagnetic dampers enable precise control of mechanical vibrations, offering superior braking performance and response speed. When designing products using high-speed motors, electromagnetic dampers further eliminate vibrations caused by motor rotation. When the mass of the container and liquid held in the rotating component 22 is large, the current flowing through the electromagnetic damper increases accordingly during operation, generating a greater damping force to suppress the transmission of this mechanical vibration to the housing 10. Conversely, when the mass of the container and liquid held in the rotating component 22 is small, the amplitude of the mechanical vibration generated during operation is small, and the current flowing through the electromagnetic damper decreases accordingly. Furthermore, electromagnetic dampers have low energy consumption, operate without noise, and are more environmentally friendly.

[0068] Compared to oil-based dampers, electromagnetic dampers are characterized by zero liquid leakage. Electromagnetic dampers do not require liquid support, avoiding the problem of leakage from oils and other substances. They use current to control the damping magnitude, improving the dynamic performance of the system, making them more versatile in various environments. Furthermore, the absence of leakage ensures that the equipment will not contaminate food during use, thus improving the stability and safety of equipment operation.

[0069] In summary, electromagnetic dampers outperform friction dampers in terms of energy consumption, environmental friendliness, performance flexibility, service life, reliability, and adaptability. Therefore, electromagnetic dampers should be the preferred choice for product upgrades and optimizations. Furthermore, with continuous technological advancements and further cost reductions, the cost of electromagnetic dampers is now within an acceptable range.
