CN2529599Y - Cyclone device of small hand-held household duster - Google Patents

Abstract

The utility model discloses a cyclone device of small hand-held household duster, containing a chassis, an air inlet and a dust removing device; wherein the lower of the chassis has a laid clapboard which forms an air inlet channel with the bottom of the chassis; and the laid clapboard has an air channel outlet which has a cover lid and is connected to the laid clapboard by one side. The inlet air of the device can produce cyclone in the chassis, thus reducing the possibility that dust blocks the dust removing device and avoiding the motor of a cleaner be burned because of overloading; and at the same time, the exhausted air of the cleaner is relatively clean, thus avoiding secondary pollution.

Description

The cyclone of small hand-held formula domestic vacuum cleaners

Technical field

The utility model relates to a kind of small hand-held formula domestic vacuum cleaners.

Background technology

Raising along with The development in society and economy and living standards of the people, dust catcher enters family just more and more, and the type of dust catcher also increased a lot, for example, a kind of small hand-held formula domestic vacuum cleaners of tidying up desktop, bed, sofa etc. that are specifically designed to arranged in the market.As shown in Figure 1, this dust catcher mainly is made up of motor in casing, the casing and negative pressure device, dust enters dust catcher by air inlet, by dust filtration device after motor, discharge from air outlet again, the greatest drawback of this dust catcher is, dust is directly beaten on dust filtration device from air inlet, and dust filtration device adopts the individual layer plane to filter, so dust filtration device will stop up in very short time, cause motor overload, temperature rise rapidly, finally to cause burning, punish severely hidden danger on performance and safety so this dust catcher has.

Summary of the invention

The utility model purpose is: the cyclone that a kind of small hand-held formula domestic vacuum cleaners are provided, the air intake of this device is not directly to beat on dust filtration device, but the rotation back is sucked by dust filtration device in body, so just reduced the possibility of dust obstruction dust filtration device, avoid motor of dust collector to burn out because of overload, improved the security and the reliability of dust catcher, the air that makes dust catcher discharge simultaneously is cleaner clean, has avoided the generation of secondary pollution.

The technical solution of the utility model is: a kind of cyclone of small hand-held formula domestic vacuum cleaners, comprise casing, air inlet, dust filtration device, the bottom is provided with diaphragm plate in the described casing, diaphragm plate and bottom of shell form air inlet duct, diaphragm plate is provided with ducting outlet, ducting outlet is provided with cover plate, and a side of cover plate is connected with diaphragm plate.

The further technical scheme of the utility model is: a kind of cyclone of small hand-held formula domestic vacuum cleaners, comprise casing, air inlet, dust filtration device, the bottom is provided with diaphragm plate in the described casing, diaphragm plate and bottom of shell form air inlet duct, diaphragm plate is provided with ducting outlet, ducting outlet is provided with cover plate, and a side of cover plate is connected with diaphragm plate; Described air inlet is positioned at the front end of casing, and the air inlet direction is slightly downward, and its axis and horizontal plane have an angle.

The utility model has the advantages that:

1. air inlet of the present utility model enters in the casing through the air inlet duct of diaphragm plate and bottom of shell formation, diaphragm plate is provided with ducting outlet, ducting outlet is provided with the cover plate that a side is connected with diaphragm plate, wind is uncapped that plate is beaten on casing inner wall and is formed whirlwind during use, rather than directly beat on dust filtration device, dust filtration device just is not easy blockedly like this, has avoided the major accident that causes that motor overload burns out.

2. dust of the present utility model is filtered by dust filtration device after forming whirlwind again, and the air that makes the dust catcher air outlet discharge is cleaner, has avoided the generation of secondary pollution.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further described:

Fig. 1 is the prior art constructions schematic diagram;

Fig. 2, Fig. 3 are structural representation of the present utility model.

Wherein: 1 casing; 2 air inlets; 3 dust filtration devices; 4 diaphragm plates; 5 air inlet ducts; 6 ducting outlets; 7 cover plates.

The specific embodiment

Embodiment: as Fig. 2, shown in Figure 3, a kind of cyclone of small hand-held formula domestic vacuum cleaners, comprise casing [1], air inlet [2], dust filtration device [3], the interior bottom of described casing [1] is provided with diaphragm plate [4], diaphragm plate [4] forms air inlet duct [5] with casing [1] bottom, diaphragm plate [4] is provided with ducting outlet [6], and ducting outlet [6] is provided with cover plate [7], and a side of cover plate [7] is connected with diaphragm plate [4]; Described air inlet [2] is positioned at the front end of casing [1], and air inlet [2] direction is slightly downward, and its axis and horizontal plane have an angle.

Air inlet of the present utility model [2] enters in the casing [1] through diaphragm plate [4] and the air inlet duct [5] that casing [1] bottom forms, diaphragm plate [4] is provided with ducting outlet [6], ducting outlet [6] is provided with the cover plate [7] that a side is connected with diaphragm plate [4], wind is uncapped that plate [7] is beaten on casing [1] inwall and is formed whirlwind during use, rather than directly beat on dust filtration device [3], dust filtration device [3] just is not easy blockedly like this, has avoided the major accident that causes that motor overload burns out; Dust of the present utility model is filtered by dust filtration device [3] after forming whirlwind again, and the air that makes the dust catcher air outlet discharge is cleaner, has avoided the generation of secondary pollution.

Claims (2)

1. the cyclone of small hand-held formula domestic vacuum cleaners, comprise casing [1], air inlet [2], dust filtration device [3], it is characterized in that: the interior bottom of described casing [1] is provided with diaphragm plate [4], diaphragm plate [4] forms air inlet duct [5] with casing [1] bottom, diaphragm plate [4] is provided with ducting outlet [6], ducting outlet [6] is provided with cover plate [7], and a side of cover plate [7] is connected with diaphragm plate [4].

2. the cyclone of small hand-held formula domestic vacuum cleaners according to claim 1 is characterized in that: described air inlet [2] is positioned at the front end of casing [1], and air inlet [2] direction is slightly downward, and its axis and horizontal plane have an angle.
