Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaners, and specifically relates to a vacuum cleaner. Background Technique

[0002] A vacuum cleaner is a cleaning appliance mainly used for cleaning the floors, sofas, furniture, etc. in a household. By driving a scroll fan through a motor inside, a negative-pressure wind force is formed to suck the dust and dirt to be cleaned into the inside of a dust collection box. There are various types of vacuum cleaners, including handheld, upright, and horizontal types. The handheld type is simple and convenient to use and can meet greater usage requirements.

[0003] The invention with the publication number CN108272385A discloses a handheld vacuum cleaner, which is communicated with an air inlet through a dust cup air outlet and a dust cup air inlet from an air suction port. Thus, the dust-containing air flow can be sucked into the machine body through the air inlet and tangentially flow into a dust cup assembly through the dust cup air inlet to achieve dust-air cyclone separation. The separated dust can gather downward at the bottom of the dust cup assembly.

[0004] However, the above-mentioned disclosed handheld vacuum cleaner still has the following problems in actual use: After sucking dust and air through the negative pressure of the vacuum cleaner and completing dust collection by means of cyclone separation, such cyclone dust separation usually adopts a right-angle air guiding structure. After the air flow carrying dust enters the air duct, it directly collides with the right-angle channel, thereby greatly weakening the air flow velocity, increasing the time and energy consumption required for separation, and increasing the suction loss within the volume range.

[0005] Therefore, we propose a vacuum cleaner to solve the problems raised above. Content of the Utility Model

[0006] The purpose of the utility model is to provide a vacuum cleaner to solve the problem that after sucking dust and air through the negative pressure of the vacuum cleaner and completing dust collection by means of cyclone separation, such cyclone dust separation usually adopts a right-angle air guiding structure. After the air flow carrying dust enters the air duct, it directly collides with the right-angle channel, thereby greatly weakening the air flow velocity, increasing the time and energy consumption required for separation, and increasing the suction loss within the volume range.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A vacuum cleaner includes a vacuum cleaner body and a dust bucket body inserted below the vacuum cleaner body. A drive motor is arranged inside the vacuum cleaner body, and a guide scroll fan is arranged on one side of the drive motor. A guide housing is installed inside the dust bucket body. The top end of the guide housing is connected to the bottom end of an air inlet channel, and the air inlet channel is cut into the top of the guide housing in a special-shaped structure. It is combined with the guide housing to form a spiral volute structure to reduce the influence on the gas flow velocity and improve the speed of gas and dust entering the inside of the guide housing.

[0008] Preferably, the top end of the air inlet channel is in communication with the dust suction hole at the left end of the vacuum cleaner body, and the air inlet channel is arranged in an arc structure. It combines with the diversion housing to form a spiral volute structure to reduce the influence on the gas flow rate and improve the speed of gas and dust entering the interior of the diversion housing.

[0009] Preferably, a filter cylinder for separating air and dust is installed inside the diversion housing, and a sealing locking disc is fixedly arranged at the rear end of the filter cylinder. The filter cylinder is detachably installed inside the diversion housing through the sealing locking disc.

[0010] Preferably, a sealing panel is fixedly arranged at the right end of the diversion housing, and an air inlet slot for re-filtering the separated gas is formed inside the sealing panel.

[0011] Preferably, a diversion cavity is formed inside the diversion housing, and a dust discharge slot is formed on the front surface of the diversion housing. The diversion cavity formed inside the diversion housing is in through connection with the air inlet slot formed inside the sealing panel.

[0012] Preferably, the diversion housing is in through connection with the dust bucket body through the dust discharge slot formed on the front surface, and the diversion cavity is in through connection with the air inlet channel at the top end of the diversion housing.

[0013] Preferably, after the dust bucket body is installed with the vacuum cleaner body, the sealing panel on the right side of the diversion housing inside the dust bucket body is located on the left side of the diversion vortex fan. By operating the drive motor and the diversion vortex fan, a negative pressure state is formed inside the dust bucket body and the diversion housing to absorb external air flow and dust.

[0014] Preferably, after the dust entering the interior of the diversion housing is separated by the filter cylinder, it enters the interior of the dust bucket body through the dust discharge slot formed on the front surface of the diversion housing. At the same time, the filtered air is discharged to the outside of the vacuum cleaner body through the rear of the interior of the diversion housing.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: For this vacuum cleaner, the diversion housing inside the dust bucket body is connected to the dust suction hole of the vacuum cleaner body through the arc-shaped air inlet channel, reducing the loss of gas flow rate during the transmission of air flow, so that after the dust is separated, it is discharged through the rear of the diversion housing, improving the separation efficiency while increasing the air flow speed and reducing the energy consumption loss of the vacuum cleaner body. The specific content is as follows:

[0016] 1. The impurity filtering cylinder body is installed inside the rotating volute through the sealing and locking disc at the front end, achieving sealing while separating dust from the airflow. At the same time, the dust bucket body equipped with the diversion housing is installed below the vacuum cleaner body, so that the air inlet channel above the diversion housing is interconnected with the dust suction hole, so that the negative pressure formed during subsequent work can introduce the airflow into the air inlet channel and the inside of the diversion housing for separation.

[0017] 2. The drive motor drives the diversion vortex fan to rotate, and the exhaust slots opened on both the front and rear sides of the vacuum cleaner body export the airflow, causing a negative pressure effect to form inside the interconnected dust bucket body. The vacuum cleaner body sucks in dust and air through the dust suction hole at the left end;

[0018] The airflow enters through the air inlet channel. The arc-shaped air inlet channel can reduce the velocity loss of the gas during the transmission of the airflow, guiding the gas and dust to the inside of the diversion housing at a higher speed. During the rotational flow, the dust moves to the edge close to the inner wall of the diversion housing through the centrifugal effect, and overflows to the outside when passing through the impurity discharge slot, so as to break away from the diversion housing and enter the inside of the dust bucket body for subsequent collection;

[0019] Furthermore, the airflow continues to flow to the right along the rear inside of the diversion housing. After the sealing panel at the right end of the diversion housing re-filters the small-diameter dust mixed in the gas, the airflow is discharged outside the vacuum cleaner body following the rotation of the diversion vortex fan, so as to improve the separation efficiency while increasing the airflow velocity and preventing the energy consumption of the vacuum cleaner body from increasing.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1 - 5 , the present invention provides the following technical solutions:

[0028] Embodiment 1: To solve the problem of large suction loss when the existing vacuum cleaner body 1 is in use, therefore, in this embodiment, through the following technical solutions, a vacuum cleaner includes a vacuum cleaner body 1 and a dust bucket body 2 inserted below the vacuum cleaner body 1. A drive motor 3 is arranged inside the vacuum cleaner body 1, and a flow guiding vortex fan 4 is arranged on one side of the drive motor 3.

The top end of the flow guiding outer shell 5 is connected to the bottom end of the air inlet channel 6, and the air inlet channel 6 is in a special-shaped structure and cuts into the top of the flow guiding outer shell 5.

[0029] After the dust bucket body 2 and the vacuum cleaner body 1 are installed, the sealing panel 7 on the right side of the flow guiding outer shell 5 inside the dust bucket body 2 is located on the left side of the flow guiding vortex fan 4. By the operation of the drive motor 3 and the flow guiding vortex fan 4, a negative pressure state is formed inside the dust bucket body 2 and the flow guiding outer shell 5, so as to absorb external air flow and dust.

[0030] As Figures 1 - 3 shown, first, the filter impurity cylinder body 11 is installed inside the flow guiding outer shell 5 and is snap-fitted to the front end of the flow guiding outer shell 5 through the sealing locking disc 12 at the front end of the filter impurity cylinder body 11. Then, the flow guiding outer shell 5 is installed inside the dust bucket body 2, and the dust bucket body 2 is snap-fitted below the vacuum cleaner body 1, so that the air inlet channel 6 connected through the top end of the flow guiding outer shell 5 is in through connection with the suction hole opened at the left end of the vacuum cleaner body 1. At the same time, the sealing panel 7 connected through the rear of the flow guiding outer shell 5 fits below the vacuum cleaner body 1, ensuring that the air inlet slot hole 8 opened inside the sealing panel 7 can form a negative pressure effect inside the dust bucket body 2 when the drive motor 3 drives the flow guiding vortex fan 4 to work.

[0031] Embodiment 2: To solve the problem of large suction loss when the existing vacuum cleaner body 1 is in use, in this embodiment, through the following technical solutions, the top end of the air inlet channel 6 is interconnected with the dust suction hole at the left end of the vacuum cleaner body 1, and the air inlet channel 6 is arranged in an arc structure. It combines with the diversion housing 5 to form a vortex-shaped volute structure to reduce the influence on the gas flow velocity and improve the speed of gas and dust entering the interior of the diversion housing 5; a filter cylinder body 11 for separating air and dust is installed inside the diversion housing 5, and a sealing locking disc 12 is fixedly arranged at the rear end of the filter cylinder body 11, and the filter cylinder body 11 is detachably installed inside the diversion housing 5 through the sealing locking disc 12.

[0032] A sealing panel 7 is fixedly arranged at the right end of the diversion housing 5, and an air inlet slot hole 8 for re-filtering the separated gas is opened inside the sealing panel 7; a diversion cavity 9 is opened inside the diversion housing 5, and a dust discharge slot opening 10 is opened on the front surface of the diversion housing 5, and the diversion cavity 9 opened inside the diversion housing 5 is connected in a through manner with the air inlet slot hole 8 opened inside the sealing panel 7.

[0033] The diversion housing 5 is connected in a through manner with the dust bucket body 2 through the dust discharge slot opening 10 opened on the front surface, and the diversion cavity 9 is connected in a through manner with the air inlet channel 6 at the top end of the diversion housing 5; after the dust entering the interior of the diversion housing 5 is separated by the filter cylinder body 11, it enters the interior of the dust bucket body 2 through the dust discharge slot opening 10 opened on the front surface of the diversion housing 5, and at the same time, the filtered air is discharged to the outside of the vacuum cleaner body 1 through the rear of the interior of the diversion housing 5.

[0034] As Figure 1 、 Figures 4 - 5 shown, a driving motor 3 installed inside the vacuum cleaner body 1 drives the diversion vortex fan 4 at the left end to rotate. The air exhaust slot holes opened on the front and rear sides of the vacuum cleaner body 1 lead out the air flow, and a negative pressure effect is formed inside the connected dust bucket body 2, and the vacuum cleaner body 1 sucks in dust and air through the dust suction hole at the left end;

[0035] Furthermore, the air flow first enters through the air inlet channel 6 connected to the top end of the diversion housing 5. The arc-shaped air inlet channel 6 can reduce the gas flow velocity loss during the transmission of the air flow, and guide the gas and dust to the interior of the diversion housing 5 at a higher speed. Then, the air flow and dust first rotate around the filter cylinder body 11 inside the diversion housing 5. The dust with weight moves to the edge near the inner wall of the diversion housing 5 through the centrifugal effect during the rotation flow, and overflows to the outside when passing through the dust discharge slot opening 10, so as to break away from the diversion housing 5 and enter the interior of the dust bucket body 2 for subsequent collection;

[0036] At the same time, the airflow separated from the dust enters the interior of the filter cylinder 11, and continues to flow to the right along the rear of the guide shell 5 under the effect of negative pressure. The sealing panel 7 at the right end of the guide shell 5 filters the small-diameter dust mixed in the gas again, so that the airflow follows the rotation of the guide turbofan 4 and is discharged to the outside of the vacuum cleaner body 1, so as to improve the separation efficiency while increasing the airflow speed and prevent the energy consumption of the vacuum cleaner body 1 from increasing.
