Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an air conditioning water pumping device and an air conditioner. Background Technology

[0002] In existing technologies, air conditioner water-discharging devices typically use a flywheel to eject condensate from a storage tank, thereby cooling the condenser. During this process, the flywheel needs to be immersed in the condensate to a certain depth—the optimal discharging depth—to efficiently complete the discharging action. However, in actual operation, the condensate generation rate dynamically changes due to factors such as ambient temperature and humidity, and air conditioning load, making it difficult to maintain the water level in the storage tank stably within the optimal range.

[0003] When ambient humidity is high or the cooling load is heavy, condensate forms rapidly, causing the water level in the storage tank to rise quickly. This results in the flywheel being partially or completely submerged in water, significantly increasing rotational resistance, reducing flywheel speed, decreasing water pumping efficiency, and even causing motor overload. Conversely, when the environment is dry or the machine operates under high load for extended periods, condensate formation is insufficient and evaporation is accelerated, causing the water level to drop below the minimum operating level. The flywheel cannot effectively carry water, leading to a sharp decrease in condenser heat dissipation capacity, increased duct temperature, and potential softening, deformation, or even melting of the plastic fan blades. This results in reduced airflow, increased noise, and in severe cases, triggers the entire unit's overheat protection shutdown, posing a significant safety hazard.

[0004] Furthermore, traditional structures often employ fixed-volume water tanks or simple pump drainage mechanisms, lacking dynamic coordination and control over the water storage and replenishment process. They cannot proactively adjust the condensate supply based on actual water level requirements, resulting in the water pumping device operating under suboptimal conditions for extended periods. Therefore, existing air conditioning water pumping devices cannot ensure the flywheel always operates within the optimal water depth range, severely impacting the stability and safety of air conditioning operation.

The drive motor drives the end of the rotating rod near the push rod to reciprocate in a direction closer to or further away from the first fixed plate.

[0011] In one embodiment of the air conditioner water pumping device of this utility model, the rotating rod is recessed in a storage groove in the direction away from the push rod.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0021] This utility model addresses the technical problem of unstable movement of the main air outlet door panel in existing air conditioners during opening and closing, proposing an air conditioner water pumping device, with reference to... Figures 1 to 8The air conditioner water pumping device includes: a water pumping assembly 10, including a water storage tank 11 and a water pumping flywheel 12, with a portion of the water pumping flywheel 12 disposed in the water storage tank 11; a water receiving tray 21 for receiving condensate produced by the evaporator; and a condensate water regulating assembly 30, including a drive motor 31, a water storage tank 32, an inlet pipe 33, and an outlet pipe 34. The drive motor 31 is connected to the water storage tank 32, and one end of the inlet pipe 33 and the outlet pipe 34 are both connected to the water storage tank 32. The volume of the water storage tank 32 is variable, and the drive motor 31 drives the water storage tank 32 to change its volume. The other end of the inlet pipe 33 is connected to the water receiving tray 21, and the other end of the outlet pipe 34 is connected to the water storage tank 11.

[0022] The air conditioner water pumping device of this invention is applied to the condensate treatment system of a portable air conditioner. The water pumping component 10 is set in the area of ​​the air conditioner chassis 40, wherein the water storage tank 11 is used to temporarily hold condensate, and the water pumping flywheel 12 is partially immersed in the condensate in the water storage tank 11. It is driven to rotate by an independent drive source, and splashes water onto the fins of the condenser 20 to achieve evaporative heat dissipation and cooling of the condenser 20.

[0023] The drip tray 21 is located below the evaporator and is used to collect the condensate generated during the refrigeration process, which is then discharged naturally by gravity. The condensate control component 30 is integrated into the internal space of the air conditioner. The water storage tank 32 adopts an accordion-shaped telescopic structure made of flexible material. One end of the tank is provided with a first fixing plate 351. The inlet pipe 33 and the outlet pipe 34 are both connected to the first fixing plate 351. The other end of the inlet pipe 33 is connected to the drain outlet of the drip tray 21, and the other end of the outlet pipe 34 leads to the water storage tank 11.

[0024] When the drive motor 31 receives the control command, it drives the movable end of the water storage tank 32 to reciprocate in a straight line through the transmission mechanism, thereby changing its internal volume: when the water storage tank 32 is stretched, a negative pressure is formed inside, and condensate is drawn into the water storage tank 32 from the water receiving pan 21 through the water inlet pipe 33 for storage; when the water storage tank 32 is compressed, the water inside is pressurized and quantitatively replenished to the water storage tank 11 through the water outlet pipe 34.

[0025] By adjusting the extension and retraction stroke and frequency of the water storage tank 32, precise control of the condensate supply can be achieved, ensuring that the water level in the water storage tank 11 is always maintained within the optimal depth range for efficient operation of the water-operating flywheel 12. In specific implementations, the water storage tank 32 can be made of hydrolysis-resistant TPU material, and the drive motor 31 can be a micro stepper motor in conjunction with a linkage mechanism to achieve reciprocating push-pull operation.

[0026] Furthermore, a water level sensor is installed in the water storage tank 11 to provide real-time water level signals to the controller, forming a closed-loop control logic that further enhances the system's intelligence and operational stability. This structure effectively solves the problems of decreased water pumping efficiency and poor heat dissipation caused by water level fluctuations due to environmental changes, thereby improving the safety and reliability of air conditioning operation.

[0027] In one embodiment, the water storage tank 32 includes a first fixed plate 351 and a telescopic variable capacity bag 321. The water inlet pipe 33 and the water outlet pipe 34 are connected to the first fixed plate 351. The telescopic variable capacity bag 321 is disposed on the side of the first fixed plate 351 away from the connection between the water inlet pipe 33 and the water outlet pipe 34. The drive motor 31 is connected to the side of the telescopic variable capacity bag 321 away from the first fixed plate 351.

[0028] The water storage tank 32 is composed of a first fixed plate 351 and a telescopic variable capacity bag 321. The first fixed plate 351 serves as a structural connection reference component and is fixedly installed on the internal bracket of the air conditioner. The inlet pipe 33 and the outlet pipe 34 are coaxially or parallelly connected to the first fixed plate 351, and a sealing joint ensures that the connection is leak-proof. Specifically, the first fixed plate 351 is one side plate of the protective shell 35.

[0029] The telescopic variable-capacity bag 321 is a foldable bladder made of flexible pressure-resistant material. One end is sealed and fixed to the side of the first fixed plate 351 facing the water storage tank 11, while the other end is a movable free end. The bag is accordion-shaped or corrugated, allowing it to freely expand and contract in the axial direction to change its internal volume. A second movable plate 352 is connected to the outer side of the free end of the telescopic variable-capacity bag 321 away from the first fixed plate 351. The output end of the drive motor 31 is connected to the second movable plate 352 via a push rod 3222 mechanism, thereby directly applying a push-pull force to drive the telescopic variable-capacity bag 321 to expand or compress. When the telescopic variable-capacity bag 321 is stretched, a negative pressure is formed inside, and condensate is automatically drawn into the water receiving tray 21 through the water inlet pipe 33. When compressed, the internal water is pressurized and discharged into the water storage tank 11 through the water outlet pipe 34.

[0030] This structure allows for controllable storage and release of condensate, avoiding the malfunction of the flywheel 12 caused by water level fluctuations in traditional fixed water tanks. In practical implementation, the telescopic variable-capacity bag 321 can be made of multi-layer composite silicone rubber or TPU material, possessing good elasticity, aging resistance, and sealing performance. This design not only enhances the flexibility of water level adjustment but also supports the miniaturization and compactness of the entire machine.

[0031] In one embodiment, the telescopic variable-capacity bag 321 has multiple telescopic pleats arranged in an array along the direction from the drive motor 31 toward the first fixed plate 351.

[0032] In this embodiment, the telescopic variable-capacity bag 321 extends axially along the direction of the drive motor 31 pointing towards the first fixed plate 351, and has multiple telescopic pleated structures evenly distributed circumferentially and arranged in an axial array. These pleats are folded in a ring or U-shaped corrugated shape in a free state, making the telescopic variable-capacity bag 321 form a flexible structure similar to an accordion or a bellows. When the drive motor 31 drives the second moving plate 352 to move away from the first fixed plate 351 through the push rod 3222, the pleats unfold step by step, the telescopic variable-capacity bag 321 is stretched, the internal volume increases, and negative pressure is generated, thereby drawing condensate water from the water receiving tray 21 through the water inlet pipe 33; when the drive motor 31 drives in the opposite direction, causing the second moving plate 352 to move closer to the first fixed plate 351, the pleats compress and close in sequence, the internal space decreases, the pressure increases, and the stored condensate water is forced into the water storage tank 11 through the water outlet pipe 34, realizing controllable water replenishment.

[0033] The design of this pleated structure not only ensures the smooth movement and reliable sealing of the telescopic variable capacity bag 321 during repeated expansion and contraction, but also effectively avoids material fatigue cracking caused by local stress concentration. In specific implementations, the shape of the pleats can be semi-circular, V-shaped, or trapezoidal, and their number and depth are optimized according to the required maximum water storage capacity and minimum compression volume to meet the condensate management needs of different models.

[0034] Furthermore, the pleated inner wall can be treated with a hydrophobic coating to reduce moisture residue and improve drainage efficiency. This structure, combined with the precise control of the drive motor 31, enables on-demand storage and release of condensate, ensuring that the water pumping assembly 10 always operates under optimal water level conditions, thereby improving water pumping efficiency and overall machine safety.

[0035] In one embodiment, the condensate control assembly 30 further includes a drive rod assembly 322, which is disposed between the telescopic variable capacity bag 321 and the drive motor 31, and the drive rod assembly 322 is rotatably connected to the telescopic variable capacity bag 321.

[0036] In this embodiment, the condensate control assembly 30 further includes a drive rod assembly 322, which is disposed between the drive motor 31 and the telescopic variable-capacity bag 321, and is used to convert the rotational motion of the drive motor 31 into linear reciprocating drive of the telescopic variable-capacity bag 321. Specifically, one end of the drive rod assembly 322 is connected to the output shaft of the drive motor 31, and the other end is rotatably connected to the second moving plate 352 of the telescopic variable-capacity bag 321 through a hinge structure, that is, the moving part connected to the free end of the telescopic variable-capacity bag 321 away from the first fixed plate 351.

[0037] When the drive motor 31 starts, its output shaft drives the rotating rod 3221 in the drive rod assembly 322 to rotate. The rotating rod 3221 transmits power through its hinge point with the push rod 3222, causing the push rod 3222 to swing, thereby pushing or pulling the second moving plate 352 to move axially, thus compressing or stretching the telescopic variable-capacity bag 321. This rotary connection method allows the drive rod assembly 322 to adapt to angle changes during movement, avoiding jamming or structural damage caused by rigid connections, and ensuring smooth and reliable telescopic action.

[0038] The drive rod assembly 322 can be made of metal or high-strength engineering plastic, with wear-resistant bushings or self-lubricating bearings at the hinge points to improve its service life. In actual assembly, the movement trajectory of the drive rod assembly 322 can be guided by a limiting structure to prevent lateral deviation. Through this drive method, the system can precisely control the rotation angle and direction of the drive motor 31 based on the water level feedback signal from the water storage tank 11, thereby adjusting the volume change of the telescopic variable-capacity bag 321 and achieving intelligent scheduling of condensate water. This structure effectively ensures that the water-pumping flywheel 12 always operates within the optimal water depth range, enhancing the stability and safety of the air conditioning operation.

[0039] In one embodiment, the drive rod assembly 322 includes a rotating rod 3221 and a push rod 3222. The drive motor 31 is a stepper motor. The rotating rod 3221 is connected to the output shaft of the drive motor 31. The two ends of the push rod 3222 are rotatably connected to the rotating rod 3221 and the telescopic variable-capacity bag 321, respectively. The drive motor 31 drives the end of the rotating rod 3221 near the push rod 3222 to reciprocate towards or away from the first fixed plate 351.

[0040] In this embodiment, the drive rod assembly 322 consists of a rotating rod 3221 and a push rod 3222. One end of the rotating rod 3221 is fixedly connected to the output shaft of the stepper motor, and the other end is connected to one end of the push rod 3222 through a hinge structure. The other end of the push rod 3222 is connected to the second movable plate 352 of the telescopic variable-capacity bag 321 through a rotating connector, thereby transmitting power to the movable end of the telescopic variable-capacity bag 321.

[0041] The drive motor 31 is a stepper motor, which enables precise angle control and position positioning, facilitating fine adjustment of the telescopic stroke. When the stepper motor rotates forward, the rotating rod 3221 drives the push rod 3222 to move, causing it to push the second moving plate 352 towards the first fixed plate 351, compressing the telescopic bag 321 and draining water. When the stepper motor rotates in the reverse direction, the push rod 3222 pulls the second moving plate 352 away from the first fixed plate 351, stretching the telescopic bag 321 and creating a negative pressure inside, drawing condensate water from the water receiving tray 21 through the water inlet pipe 33.

[0042] During its movement, the end of the rotating rod 3221 near the push rod 3222 swings along an arc trajectory, driving the push rod 3222 to achieve a near-linear reciprocating push-pull motion. This motion method features a compact structure and reliable transmission. By controlling the number and frequency of pulse signals from the stepper motor, the swing angle and speed of the rotating rod 3221 can be precisely controlled, thereby adjusting the expansion and contraction of the telescopic variable-capacity bag 321 and the water discharge rate to meet the condensate scheduling needs under different operating conditions.

[0043] This drive structure, in conjunction with the water level sensor feedback, can form a closed-loop control system to ensure that the water level in the water storage tank 11 is always maintained within the optimal depth range for efficient operation of the water jet flywheel 12, effectively avoiding problems such as excessive flywheel resistance due to excessive water level or heat dissipation failure caused by excessively low water level.

[0044] In one embodiment, the rotating rod 3221 is recessed in a direction away from the push rod 3222 to form a storage groove 3223. When the telescopic variable capacity bag 321 is moving towards the side closer to the drive motor 31, the push rod 3222 moves into the storage groove 3223.

[0045] In this embodiment, the rotating rod 3221 is provided with a receiving groove 3223 recessed towards the side away from the push rod 3222. The receiving groove 3223 is opened radially or obliquely along the rotating rod 3221, and its shape is adapted to the local contour of the push rod 3222, for accommodating part of the push rod 3222 during a specific movement phase. When the telescopic variable capacity bag 321 moves towards the side closer to the drive motor 31, i.e., in the compressed state, the push rod 3222 swings under the drive of the rotating rod 3221, and its end near the rotating rod 3221 moves towards the side of the rotating rod 3221 body. At this time, part of the push rod 3222 gradually embeds into the receiving groove 3223, forming a spatially overlapping accommodating structure.

[0046] This design allows the push rod 3222 to be closer to the body of the rotating rod 3221 during movement, effectively reducing the outline size of the drive rod assembly 322 in the minimum installation space and avoiding interference with the surrounding structure. It is especially suitable for installation environments with compact interior space in air conditioning systems.

[0047] The inner wall surface of the storage slot 3223 is smooth to reduce frictional resistance when the push rod 3222 slides in, ensuring smooth movement. This structure allows the drive motor 31 to be placed closer to the telescopic variable capacity bag 321 while achieving the same telescopic stroke, thereby optimizing the overall layout and improving structural compactness.

[0048] Furthermore, under the precise control of the stepper motor, the cooperation between the receiving slot 3223 and the push rod 3222 does not affect the transmission accuracy; on the contrary, it enhances motion stability by limiting the lateral offset of the push rod 3222. This design not only improves the integration of the mechanical structure but also provides effective support for the miniaturization and high-reliability operation of the air conditioner water dispensing device.

[0049] In one embodiment, the condensate control assembly 30 further includes a protective shell 35, with the first fixing plate 351 disposed on the side of the protective shell 35 near the water pumping assembly 10, and the drive motor 31, the drive rod assembly 322, and the telescopic variable capacity bag 321 all disposed in the protective shell 35.

[0050] In this embodiment, the condensate control assembly 30 also includes a structurally complete protective shell 35, which is a box-shaped or cylindrical shell made of corrosion-resistant, high-strength engineering plastics or metal materials, used to house and protect the internal moving parts.

[0051] The first fixing plate 351 is fixedly installed on one end face of the protective shell 35, and this side is located close to the water spraying assembly 10, so that the water outlet pipe 34 can be connected to the water storage tank 11 through a short path, reducing flow resistance and leakage risk. The water inlet pipe 33 is introduced from the outside of the protective shell 35, passes through the first fixing plate 351 and communicates with the inside of the telescopic variable capacity bag 321.

[0052] The main components of the drive motor 31, drive rod assembly 322, and telescopic variable capacity bag 321 are all built into the protective shell 35, forming a closed structure. This effectively prevents condensation from splashing out, dust from entering, or foreign objects from getting stuck in the transmission mechanism, thus improving the system's sealing performance and operational reliability.

[0053] The protective housing 35 contains a mounting base for fixing the drive motor 31 and a support structure for guiding the movement of the drive rod assembly 322, ensuring the stability of the rotating rod 3221 and the push rod 3222 during swinging. Simultaneously, the protective housing 35 also serves as structural support and positioning, allowing the entire condensate control assembly 30 to be pre-assembled and installed as a single module, improving production efficiency.

[0054] During air conditioner operation, this enclosed structure also reduces mechanical noise generated by the drive mechanism, improving the overall quietness of the unit. Furthermore, a drain hole or sealing plug can be installed at the bottom of the protective casing 35 for easy cleaning of accumulated liquid during maintenance. This integrated design not only enhances the unit's environmental adaptability and lifespan but also provides favorable conditions for achieving a neat and modular internal layout for the air conditioner.

[0055] In one embodiment, a guide groove 353 is recessed into the inner wall of the protective shell 35 near the folds, extending outward from the protective shell 35. The water storage tank 32 further includes a second movable plate 352 and a guide rod 36. The second movable plate 352 is disposed between the telescopic variable capacity bag 321 and the push rod 3222. The guide rod 36 is disposed on the surface of the second movable plate 352 near the push rod 3222, and at least one end of the guide rod 36 is slidably disposed within the guide groove 353.

[0056] In this embodiment, the internal structure of the protective shell 35 is further optimized. On at least one inner wall near the pleated area of ​​the telescopic and variable-capacity bag 321, there is a guide groove 353 that extends axially and is recessed to the outside of the protective shell 35. The guide groove 353 penetrates part of the shell wall to form a straight slide rail structure.

[0057] The water storage tank 32 also includes a second movable plate 352 and a guide rod 36. The second movable plate 352 is fixedly connected to the free end of the telescopic variable capacity bag 321 away from the first fixed plate 351, serving as a transmission connection for telescopic movement. The rod is installed on the side surface of the second movable plate 352 facing the push rod 3222, arranged perpendicular or parallel to the direction of movement, with both ends or one end extending outward and slidably embedded in the guide groove 353 to form a guiding fit structure.

[0058] When the drive motor 31 pushes the second moving plate 352 to reciprocate through the push rod 3222, the guide rod 36 slides synchronously in the guide groove 353, restricting the movement trajectory of the second moving plate 352 to only be in the axial straight direction, effectively preventing it from deflecting, tilting or swaying laterally during the extension and retraction process, thereby avoiding problems such as wrinkles, twisting, local stretching or sealing failure of the telescopic variable capacity bag 321 due to uneven force.

[0059] The inner surface of the guide groove 353 is smoothly treated and can be fitted with a low-friction slider or a self-lubricating bushing to reduce sliding resistance and improve smoothness of movement. This guide structure works in conjunction with the drive rod assembly 322 to ensure stable and accurate telescopic movement, maintaining good reliability even under frequent starts and stops or changing operating conditions. In addition, a dustproof sealing cap or elastic seal can be installed at the open end of the guide groove 353 to prevent dust and moisture from entering the groove and affecting sliding performance.

[0060] In one embodiment, the water receiving tray 21 is located above the water storage tank 32 and the water storage trough 11.

[0061] In this embodiment, the water receiving tray 21 is positioned above the water storage tank 32 and the water tank 11, its installation position higher than both, utilizing the principle of gravity flow to achieve natural transport of condensate. The water receiving tray 21 is fixed to the chassis 40 structure below the evaporator and is used to collect the condensate generated by the evaporator during the refrigeration process. Its bottom has a drain outlet, connected to the first fixed plate 351 of the water storage tank 32 via a water inlet pipe 33. Due to the high position of the water receiving tray 21, the condensate can automatically flow into the expandable variable-capacity bag 321, which is in a stretched state and has a negative pressure inside, under the action of gravity. This eliminates the need for an additional water pump or pressurization device, simplifying the system structure and reducing energy consumption and failure rate.

[0062] Meanwhile, this layout ensures a stable and reliable water intake process, avoiding problems caused by insufficient water level difference. When the water storage tank 32 is compressed, the stored condensate is discharged through the outlet pipe 34 to the water storage tank 11 located below, also achieving smooth drainage through the height difference.

[0063] This utility model also discloses an air conditioner, which includes the air conditioner water pumping device described in the above embodiments.

[0064] The air conditioner includes a casing, evaporator, condenser 20, compressor, fan, and control system. The water pumping device is installed in the chassis area 40, spatially aligned with the evaporator and condenser 20. A drip tray 21 is located directly below the evaporator to collect condensate generated during operation. The condensate enters the water storage tank 32 within the protective casing 35 via the inlet pipe 33. A drive motor 31 controls the volume change of the telescopic variable-capacity bag 321, enabling temporary storage and on-demand release of the condensate. An outlet pipe 34 transports the stored condensate to a water storage tank 11 for continuous operation of the water pumping flywheel 12. Driven by a motor, the flywheel 12 rotates, throwing water towards the high-temperature condenser fins 20, achieving efficient evaporation of the condensate and active cooling of the condenser 20.

[0065] The control system monitors the water level in the storage tank 11 in real time using a water level sensor, and intelligently adjusts the working state of the drive motor 31 based on the preset optimal water dispensing depth range. This allows the water storage tank 32 to dynamically adjust the water volume, ensuring that the water dispensing flywheel 12 is always operating within its high-efficiency range. This air conditioner not only solves the safety hazards of traditional models caused by water level fluctuations, such as decreased water dispensing efficiency, poor heat dissipation, and fan blade melting, but also extends the effective operating time before shutting off when the water level is full through a variable-volume condensate water management mechanism, improving user convenience.

[0066] This utility model also discloses a control method for an air conditioner water pumping device. (Refer to...) Figure 9 This control method is based on the real-time water level status in the water storage tank 11. It collects signals through a water level sensor and makes judgments and outputs instructions by the controller to realize intelligent regulation of the condensate scheduling component 30.

[0067] Specifically, the system presets the optimal water level range for efficient operation of the water-pumping flywheel 12 to be H1 to H2. When the current water level in the water storage tank 11 is detected to be lower than H1 and the water volume in the water storage chamber 32 is greater than the minimum water storage volume V1, the controller starts the drive motor 31, which drives the drive rod assembly 322 to push the second moving plate 352, compressing the telescopic variable capacity bag 321, and discharging the condensate stored inside into the water storage tank 11 through the outlet pipe 34, thus achieving automatic water replenishment. When the water level rises back to the range of H1 to H2, the water replenishment action stops, and the water-pumping flywheel 12 resumes normal water-pumping operation. When the water level in the water storage tank 11 is detected to be higher than H2, the drainage operation of the water storage chamber 32 is suspended, and the water-pumping flywheel 12 continues to consume water to lower the water level, avoiding increased rotational resistance due to excessive submersion of the flywheel. At the same time, the system continuously monitors the current volume of the water storage chamber 32. If it is stretched to the maximum volume V2 and still cannot meet the water storage demand, a reminder signal is issued to prompt the user to clean the water storage chamber 32 in time.

[0068] Furthermore, after completing one water replenishment cycle, the controller can further adjust the telescopic variable-capacity bag 321 to maintain its current water storage volume at 50%–70% of its maximum capacity, reserving sufficient dynamic adjustment margin to improve subsequent response speed and control accuracy. This control method achieves closed-loop management of condensate generation, storage, and use, effectively ensuring the stability and safety of the water dispensing device under various operating conditions, and enhancing the overall intelligence level of the air conditioning unit and the user experience.

[0069] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
