Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, specifically a turbine air guide assembly for a vacuum cleaner. Background Technology

[0002] A vacuum cleaner is a tool used for household cleaning. It mainly uses a motor to drive a turbine to generate suction and suck up external dust.

[0003] Existing vacuum cleaners have the following technical problems: Existing car vacuum cleaners mainly use a motor to drive a turbine to generate suction to pick up external dust, and then filter it through a filtration system. However, due to the overly simple airflow design, existing car vacuum cleaners generate loud noise when picking up dust. Furthermore, the lack of a good airflow design leads to a decrease in negative pressure at the suction inlet, and also causes eddies and airflow stagnation inside the vacuum cleaner, which reduces the suction power and causes inconvenience in daily use.

Detailed Implementation

[0022] 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. Example

[0023] Please see Figure 1 - Figure 6 A turbine air guide assembly for a vacuum cleaner includes a vacuum cleaner housing 1. The vacuum cleaner housing 1 includes an upper housing 11 and a lower housing 12 that are detachably connected. A motor 2 is fixedly installed inside the lower housing 12, and a base 4 is fixedly installed at the output end of the motor 2.

[0024] The base 4 is provided with an air guiding mechanism 5. The air guiding mechanism 5 includes a mounting base 51 fixedly installed inside the base 4. An air outlet 52 is opened inside the mounting base 51. An exhaust pipe 57 is provided at the upper end of the air outlet 52. A connecting plate 53 is fixedly installed at the upper end of the mounting base 51. A first air guiding blade 54 is fixedly installed at the upper end of the connecting plate 53. A second air guiding blade 55 is fixedly installed at the bottom end of the connecting plate 53. A third air guiding blade 56 is fixedly installed at the bottom end of the connecting plate 53 inside the second air guiding blade 55.

[0025] Furthermore, several first guide vanes 54 are arranged in a circumferential array about the connecting plate 53, several second guide vanes 55 are arranged in a circumferential array about the connecting plate 53, and the third guide vanes 56 are arranged symmetrically about the center of the connecting plate 53. The outer sides of the first guide vanes 54 and the second guide vanes 55 are arranged in opposite directions. The first guide vanes 54 are used to guide the airflow drawn in by the air inlet 63 to the second guide vanes 55, and then the second guide vanes 55 guide the introduced airflow through the third guide vanes 56 to the air outlet 52 for discharge.

[0026] Furthermore, a turbine mechanism 6 is fixedly installed on the side of the air guide mechanism 5 away from the motor 2. The turbine mechanism 6 includes a mounting bracket 61 fixedly installed on the side of the connecting plate 53 away from the base 4. Turbine blades 62 are rotatably installed inside the mounting bracket 61. An air inlet 63 is provided on the side of the mounting bracket 61 away from the connecting plate 53. The mounting bracket 61 is used to fix the turbine mechanism 6 on the connecting plate 53. Then, the motor 2 can drive the turbine blades 62 to rotate, thereby generating a strong air force to suck external dust into the vacuum cleaner.

[0027] Furthermore, a protective shell 7 is fixedly connected to the side of the base 4 away from the motor 2, and a filter module 8 is fixedly connected to the side of the protective shell 7 away from the base 4. The protective shell 7 is used to protect the air guide mechanism 5 and the turbine mechanism 6, and the filter module 8 is used to filter the inhaled dust to prevent dust from flowing into the turbine mechanism 6 and damaging the turbine blades 62.

[0028] Furthermore, a fixing mechanism 3 is provided on the outside of the motor 2. The fixing mechanism 3 includes a fixing plate 31 fixedly installed on the outside of the motor 2. A through hole 32 is provided on the outside of the fixing plate 31 around the circumference of the motor 2. A fixing rod 33 is slidably connected inside the through hole 32. A spring 34 is sleeved on the outside of the fixing rod 33. One end of the fixing rod 33 is fixedly installed inside the lower housing 12. A limit block 35 is fixedly installed on the other end of the fixing rod 33. The spring 34 is located between the lower housing 12 and the fixing plate 31.

[0029] Furthermore, the fixing mechanism 3 is used to fix the motor 2 to prevent the motor 2 from shifting when it is working. The fixing rod 33 is used to fix the fixing plate 31 to the lower housing 12. When the motor 2 vibrates, the fixing rod 33 can slide inside the through hole 32, thereby compressing the spring 34. The limiting block 35 is used to limit the fixing rod 33 to prevent the fixing rod 33 from detaching from the fixing plate 31.

[0030] Furthermore, a handle 121 is provided on the outside of the lower housing 12, and an exhaust port 122 is provided on the outside of the lower housing 12 at the upper end of the exhaust duct 57. A suction port 111 is provided on the side of the upper housing 11 away from the lower housing 12. The handle 121 is convenient for the user to hold when in use, and the exhaust port 122 is used to discharge the airflow from the exhaust duct 57 to the vacuum cleaner.

[0031] Furthermore, the output end of the motor 2 is fixedly connected to the turbine blade 62, and the air inlet 63 extends to the outside of the protective shell 7. The motor 2 is used to drive the turbine blade 62 to generate suction to suck up external dust.

[0032] The specific usage and function of this embodiment are as follows:

[0033] When in use, the staff first picks up the vacuum cleaner by holding the handle 121, and then takes the vacuum cleaner to the place in the car where the dust needs to be cleaned. Then, the motor 2 is started to drive the turbine blades 62 to rotate. As the turbine blades 62 rotate, a strong suction is generated. Then, by pointing the suction port 111 at the dust, the dust is sucked into the upper housing 11 by the suction. Then, the dust is filtered by the filter module 8. Then, the filtered airflow enters the turbine mechanism 6 through the air inlet 63.

[0034] Furthermore, the airflow is drawn into the mounting bracket 61 through the rotation of the turbine blades 62, and flows into the air guide mechanism 5 through the outside of the mounting bracket 61 for guidance. First, the airflow is guided by the first air guide blade 54. Then, the airflow impacts the inner wall of the protective shell 7 through the air guide groove between two adjacent sets of first air guide blades 54. Next, the airflow is guided by the second air guide blade 55, and then flows into the mounting base 51 through the air guide groove between two adjacent sets of second air guide blades 55. Then, it is guided by two sets of symmetrically arranged third air guide blades 56, so that the airflow enters the air outlet 52. Then, it is discharged through the exhaust pipe 57 connected to the air outlet 53, and finally, the vacuum cleaner is discharged through the exhaust port 122 provided at the upper end of the lower shell 12.

[0035] Furthermore, when the motor 2 drives the turbine blade 62 to work, the motor 2 will generate slight vibration. Then, the fixing rod 33 slides inside the sliding hole 32 with the vibration, thereby compressing the spring 34. The fixing rod 33 is limited by the limiting block 35 to prevent the fixing rod 33 from detaching from the fixing plate 31. The fixing rod 33 and the spring 34 are adjusted when the motor 2 vibrates, thereby reducing the noise generated by the vibration of the motor 2. After cleaning, the staff can remove the housing 11 to clean the dust sucked in inside. After cleaning, the upper housing 11 can be installed on the lower housing 12, and then the subsequent cleaning work can be carried out.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
