Description

Technical Field

[0001] The utility model relates to the technical field of air guide wheels, in particular to an air guide wheel structure of a vacuum cleaner. Background Art

[0002] The air guide wheel of a vacuum cleaner is an important component inside the vacuum cleaner. Its main function is to generate suction and exhaust air. The air guide wheel is usually composed of multiple blades, which are arranged on the axle at a certain angle. When the motor of the vacuum cleaner drives the air guide wheel to rotate, the blades will suck in air from the suction port of the vacuum cleaner and discharge it through the exhaust port. In this process, the rotation of the air guide wheel creates a low-pressure area, thereby forming suction.

[0003] At present, the existing air guide wheel structure of the vacuum cleaner cannot adjust the weight distribution of the air guide wheel structure as needed to achieve dynamic balance when the air guide wheel rotates at high speed, resulting in vibration due to uneven mass distribution, affecting the smooth operation of the vacuum cleaner. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that the weight distribution of the air guide wheel structure cannot be adjusted as needed to achieve dynamic balance when the air guide wheel rotates at high speed, resulting in vibration due to uneven mass distribution, and to propose an air guide wheel structure for a vacuum cleaner.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A guide wheel structure of a vacuum cleaner, comprising:

[0007] A circular mounting plate, wherein the top of the circular mounting plate is fixedly provided with a plurality of evenly distributed No. 1 air guide blades in a ring shape, and the bottom of the circular mounting plate is fixedly provided with a plurality of evenly distributed No. 2 air guide blades in a ring shape, wherein several of the No. 1 air guide blades are detachably connected with the outside of the No. 2 air guide blades with dynamic balancing buckles.

[0008] In a possible design, the dynamic balancing buckle is U-shaped, both sides of the opening of the dynamic balancing buckle are arranged with outwardly raised edges, and two undercut spikes are symmetrically arranged on both sides of the dynamic balancing buckle.

[0009] In a possible design, a same reinforcement ring is fixedly provided on the top of the No. 1 wind guide blade.

[0010] In a possible design, a placement groove is opened at the middle section of the top of the circular mounting plate, a through hole is opened at the middle of the placement groove at the top of the circular mounting plate, and a bearing is fixedly installed on the inner ring of the through hole.

[0011] In a possible design, two positioning pins are symmetrically embedded in the bottom of the circular mounting plate, and the bottom ends of the positioning pins are arc tops.

[0012] In a possible design, the number of the No. 1 air guide blades is greater than the number of the No. 2 air guide blades.

[0013] In a possible design, the gap between two adjacent No. 1 air guide blades is an air guide channel, and the gap between two adjacent No. 2 air guide blades is also an air guide channel.

[0014] In the present application, when starting to use, the motor shaft is first connected to the bearing in the hole on the top of the circular mounting plate. When the vacuum cleaner is started, the motor starts working, and its output shaft drives the entire air guide wheel structure to start rotating. As the circular mounting plate rotates, the No. 1 air guide blades evenly distributed on the top rotate synchronously. Since the number of No. 1 air guide blades is greater than that of No. 2 air guide blades, the top air inlet area is relatively large, which enhances the suction force of the vacuum cleaner. The gap between the two adjacent No. 1 air guide blades forms an air guide channel, and the external air is sucked into the vacuum cleaner through these channels. At the same time, the reinforcement ring on the top of the No. 1 air guide blade ensures the strength and stability of the blade to prevent deformation or damage during high-speed rotation.

[0015] During the rotation process, in order to maintain the dynamic balance of the air guide wheel structure and avoid vibration and noise, the No. 1 air guide blade and the No. 2 air guide blade at several key positions are detachably connected with dynamic balancing buckles on the outside. These U-shaped dynamic balancing buckles are easy to install and disassemble due to the warped edges on both sides of their openings, and the two inverted spikes symmetrically arranged on both sides ensure the stability of the buckles after installation. If dynamic balance problems are found during the initial installation or use, they can be corrected by increasing or decreasing the number of dynamic balancing buckles, or adjusting their positions, to ensure the smooth operation of the air guide wheel structure.

[0016] The No. 2 air guide blade at the bottom of the circular mounting plate guides the sucked air into the interior of the vacuum cleaner as it rotates, and together with the No. 1 air guide blade forms a complete air flow channel. The gap between the two adjacent No. 2 air guide blades also serves as an air guide channel to ensure smooth flow of air.

[0017] In order to ensure the accurate positioning of the air guide wheel structure during the installation process, two positioning pins are symmetrically embedded in the bottom of the circular mounting plate. The bottom ends of these positioning pins are designed to be arc tops to facilitate plugging with the positioning holes.

[0018] During the continuous operation of the air guide wheel structure of the vacuum cleaner, through the coordinated action of the first air guide blade and the second air guide blade, external air is continuously inhaled and directed into the vacuum cleaner to achieve the cleaning function. During long-term use, the dynamic balance buckle can be inspected and adjusted as needed to maintain the dynamic balance state of the air guide wheel structure. At the same time, the air guide wheel structure should be cleaned and maintained regularly to ensure its good working performance and extend its service life.

[0019] The utility model has the following beneficial effects:

[0020] In the utility model, through the setting of the dynamic balance buckle, align the opening of the dynamic balance buckle with the selected air guide blade and press it. The two inverted barbs symmetrically arranged on both sides of the buckle can firmly fix the buckle on the blade. Users can adjust the position and quantity of the dynamic balance buckle as needed to adjust the weight distribution of the air guide wheel structure, so that the air guide wheel reaches dynamic balance during high-speed rotation, reduce the vibration caused by uneven mass distribution, ensure the smooth operation of the vacuum cleaner, and at the same time reduce the noise during work and extend the service life of the device.

[0021] Through the setting of the dynamic balance buckle in the utility model, the position and quantity of the dynamic balance buckle can be adjusted as needed to adjust the weight distribution of the air guide wheel structure, so that the air guide wheel reaches dynamic balance during high-speed rotation, reduce the vibration caused by uneven mass distribution, and ensure the smooth operation of the vacuum cleaner.

[0031] The No. 1 air guide blade 2 is at the top of the circular mounting plate 1, and multiple No. 1 air guide blades 2 are evenly distributed along the ring. The number of these blades is designed to be more than the No. 2 air guide blade 3 to increase the top air inlet area and improve the suction efficiency. The tops of the multiple No. 1 air guide blades 2 are also fixedly connected with the same reinforcement ring 9, which surrounds the tops of all No. 1 air guide blades 2 to further enhance the overall strength and stability of the blades.

[0032] The No. 2 air guide blade 3 is at the bottom of the circular mounting plate 1, and there are also multiple No. 2 air guide blades 3 evenly distributed along the ring, and the number of the No. 1 air guide blades 3 is less than that of the No. 1 air guide blades 2. This design helps to form an effective wind pressure distribution at the bottom and optimize the airflow guidance.

[0033] In order to adjust the dynamic balance of the air guide wheel structure, the No. 1 air guide blade 2 and the No. 2 air guide blade 3 at several key positions are detachably clamped with dynamic balancing buckles 4. The dynamic balancing buckle 4 is U-shaped, and the two sides of its opening are designed to be outwardly raised edges 401 for easy installation and disassembly. At the same time, two inverted spikes 402 are symmetrically arranged on both sides of the buckle to ensure that the buckle can be firmly fixed on the blade after installation. If a dynamic balance problem is found during the initial installation or use, it can be corrected by increasing or decreasing the number of dynamic balancing buckles 4, or adjusting their position, so as to ensure the smooth operation of the air guide wheel structure.
