Description

Technical Field

[0001] This utility model relates to the field of fan blade technology, and in particular to a vacuum cleaner fan blade assembly with a sound-absorbing cavity. Background Technology

[0002] The silencing chamber is an important component of a vacuum cleaner. It effectively reduces the noise level of the vacuum cleaner during operation by changing the airflow path and slowing down the airflow speed. Although the main function of the silencing chamber is noise reduction, it does not hinder the vacuum cleaner's suction performance. On the contrary, by optimizing the airflow path and reducing airflow resistance, the silencing chamber also helps to improve the vacuum cleaner's suction efficiency and performance.

[0003] Currently, while existing vacuum cleaner fan blade assemblies can meet basic vacuuming needs, the installation and removal of the fan blades are cumbersome and inefficient, making it inconvenient for users to quickly replace them. At the same time, due to the lack of effective limiting and reinforcement measures, they are prone to loosening or instability after installation, which not only affects the operating efficiency of the vacuum cleaner but also damages the vacuum cleaner and reduces its service life. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology, which has low installation efficiency and stability, which not only affects the operating efficiency of the vacuum cleaner, but also damages the vacuum cleaner and reduces its service life. The present invention proposes a vacuum cleaner fan blade assembly with a silencing cavity.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vacuum cleaner fan blade assembly with a sound-absorbing chamber includes:

[0007] The vacuum cleaner body consists of a first outer shell, a second outer shell, and a suction tube. The first outer shell has a sound-absorbing chamber inside. A handle is fixedly installed on the top of the first outer shell, and a switch is installed at the bottom of the handle.

[0008] The fan blade mechanism is housed within the outer casing and is used to improve the stability of the fan blade mechanism during operation.

[0009] In one possible design, the fan blade mechanism includes a cavity formed on one side of the outer casing, which is connected to a silencing cavity. A fixing frame is fixedly installed on the inner wall of the cavity of the outer casing. A motor is fixedly installed on the rear side of the fixing frame. A screw is rotatably installed on the front side of the fixing frame. The output shaft of the motor is fixedly connected to the screw. A fan blade body is sleeved on the outside of the screw. A limiting plate is fixedly installed on the outside of the screw. Two limiting blocks are symmetrically fixed on the outside of the screw above the limiting plate. A through hole is formed at the center of the fan blade body. Two limiting grooves are symmetrically formed on both sides of the inner wall of the through hole. The limiting grooves are adapted to the limiting blocks. A locking nut is threadedly connected to the outside of the screw above the fan blade body.

[0010] In one possible design, several blades of the fan blade body can be detached from and engaged with dynamic balancing clips, and both sides of the dynamic balancing clips are provided with barbs.

[0011] In one possible design, the inner wall of the cavity of the outer shell is fixedly provided with a plurality of evenly distributed sound-absorbing cotton.

[0012] In one possible design, a dust bag is detachably mounted on one side of the outer casing one via screws, and the outer casing two is fitted over the dust bag.

[0013] In one possible design, the bottom of the second housing is detachably threaded with a dust box.

[0014] In one possible design, bristles are fixedly provided at the bottom of the suction tube opening.

[0015] In this application, upon initial use, first remove the fan blade body, then align the through hole on the fan blade body with the screw and insert it. Then, slowly rotate the fan blade body outside the screw, causing the limiting groove on the through hole to slowly approach the limiting block until the two are aligned. After alignment, press the fan blade body down to insert the limiting block into the limiting groove, and continue pressing the fan blade body until it abuts against the limiting plate. Then, install the locking nut on the outside of the screw until the locking nut abuts against the fan blade body, thus locking the fan blade body. Then, use the barbs on the dynamic balance buckle to lock it onto the blade at the corresponding position. Then, press the switch to start the motor. The motor's output shaft drives the fan blade body to rotate. At this time, observe whether the fan blade body shakes or vibrates when rotating. If so, you can correct it by increasing or decreasing the number of dynamic balance buckles or adjusting their positions to ensure the smooth operation of the fan blade body. After debugging, install the dust bag, and then install the outer shell and suction pipe in sequence until the vacuum cleaner body is fully installed.

[0016] When starting vacuuming, first hold the handle so your fingers can easily reach the switch, then turn on the vacuum cleaner. The power supply will power the motor, causing it to start working. The motor's output shaft drives the screw to rotate, and as the screw rotates, the fan body also rotates, generating suction. Then, aim the suction tube at the area that needs cleaning, and suck in air and dust. The sucked-in dust is blocked by the dust bag to prevent dust from entering the motor and fan body area, while the blocked dust or debris falls into the dust box for collection. During vacuuming, you can pull the vacuum cleaner body back and forth to make the bristles at the bottom of the suction tube brush the areas that need cleaning, which helps to loosen and brush up dust and debris on the floor or furniture surface, making it easier to suck into the vacuum cleaner and thus improving vacuuming efficiency.

[0017] This utility model has the following beneficial effects:

[0018] The design of the fan blade mechanism in this invention not only significantly improves the efficiency of installing and disassembling the fan blade body, making it convenient for users to quickly replace the fan blade, but also effectively enhances the stability of the fan blade body after installation through the precise matching of the limiting groove and the limiting block and the reinforcement of the locking nut, ensuring the efficient and stable operation of the vacuum cleaner.

[0019] This invention achieves precise adjustment of the dynamic balance of the fan blade body through the setting of dynamic balance buckles, effectively reducing the vibration and shaking of the fan blade during rotation, improving the smooth operation and service life of the vacuum cleaner, while also optimizing the dust collection effect and reducing the noise level.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Reference Figure 1-4 A fan blade assembly, comprising:

[0028] The vacuum cleaner body 1 is composed of a first outer shell 101, a second outer shell 102, and a suction pipe 103. The first outer shell 101 has a sound-absorbing chamber inside to reduce the noise when the vacuum cleaner is working. A handle 2 is fixedly installed on the top of the first outer shell 101 for easy hand operation. A switch is installed at the bottom of the handle 2 to control the opening and closing of the vacuum cleaner. A power supply is installed at the bottom of the first outer shell 101 to provide power to the electrical appliances inside the vacuum cleaner.

[0029] The fan blade mechanism is housed within the outer casing 101 and includes a cavity formed on one side of the outer casing 101. This cavity is connected to a sound-absorbing cavity. A mounting bracket 3 is fixedly mounted on the inner wall of the cavity. A motor 4 is fixedly mounted on the rear side of the mounting bracket 3. The motor 4 is connected to a power source via wires. A screw 5 is rotatably mounted on the front side of the mounting bracket 3. The output shaft of the motor 4 is fixedly connected to the screw 5. When the motor 4 starts, it drives the screw 5 to rotate. A fan blade body 6 is sleeved on the outside of the screw 5. When the screw 5 rotates, it drives the fan blade body 6 to generate suction. A limit plate 502 is fixedly mounted on the outside of the screw 5 to limit the insertion depth of the fan blade body 6 during installation, preventing the fan blade body 6 from being inserted too deeply and causing damage during operation.

[0030] Two limiting blocks 501 are symmetrically fixed on the outside of the screw 5 above the limiting plate 502. A through hole 601 is opened at the center of the fan blade body 6. Two limiting grooves 602 are symmetrically opened on both sides of the inner wall of the through hole 601. The limiting grooves 602 are adapted to the limiting blocks 501 to fix and limit the position of the fan blade body 6 and prevent it from shaking during rotation. A locking nut 7 is threaded on the outside of the screw 5 above the fan blade body 6 to further fix the fan blade body 6 and ensure its stability during operation.

[0031] Several blades of the fan blade body 6 can be detached and engaged with dynamic balance clips 8. Both sides of the dynamic balance clips 8 are provided with barbs 801 for engaging with the blades. By increasing or decreasing the number of dynamic balance clips 8 or adjusting their positions, the dynamic balance of the fan blade body 6 can be corrected to ensure its stability during rotation. This avoids uneven mass distribution of the fan blade body 6 during rotation, which can cause vibration due to imbalance, increase noise, damage the equipment itself, reduce the service life of the equipment, and reduce the dust collection effect.

[0032] This application can be used in the field of vacuum cleaner fan blade assembly technology with a silencing cavity, and can also be used in other fields applicable to this application.

[0034] Based on Embodiment 1, Embodiment 2 further includes: a vacuum cleaner fan blade assembly with a silencing cavity, which is applied to the technical field of vacuum cleaner fan blade assembly with a silencing cavity. The inner wall of the cavity of the outer shell 101 is fixedly provided with a plurality of evenly distributed sound-absorbing cotton 9 to further reduce the noise when the vacuum cleaner is working.

[0035] A dust bag 10 is detachably installed on one side of the outer casing 101 by screws to prevent the sucked-in dust from entering the area of ​​the motor 4 and the fan blade body 6. The outer casing 102 is fitted over the dust bag 10 to provide protection.

[0036] The bottom of the outer casing 2 102 is detachably threaded with a dust box 11 for collecting blocked dust or impurities.

[0037] The suction nozzle of the suction pipe 103 is fixedly equipped with bristles 12 at the bottom, which can brush the area to be cleaned while vacuuming, helping to loosen and brush up the dust and debris on the floor or furniture surface, making it easier to be sucked into the vacuum cleaner.

[0038] However, as is well known to those skilled in the art, the working principle and wiring method of motor 4 are commonplace and are all conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.
