Description
Technical Field
The utility model relates to an air flow conversion device applied to a dust collector.
Background
After the filter element of the industrial dust collector is used for a long time, dust can adhere to the filter element, and the filtering effect and the service life of the filter element are influenced. The conventional method is that the filter element is usually disassembled for cleaning or replacement, which is not only troublesome, but also takes time for disassembly and assembly; or the dust on the filter element is dropped by blowing air reversely through the exhaust fan, so that the exhaust fan on the dust collector needs to rotate reversely or an additional air blower is arranged, and the cost of the dust collector is increased. For this reason, an air flow converting device applied to the cleaner is required.
Disclosure of Invention
An object of the utility model is to provide a be applied to air flow conversion equipment of dust catcher, this conversion equipment conveniently realizes air flow channel's conversion.
The technical scheme of the utility model lies in: the utility model provides a be applied to air flow conversion equipment of dust catcher, includes the seat shell, be provided with the conversion valve chamber in the seat shell, the bottom of seat shell is provided with intake pipe and the outlet duct that is linked together with the conversion valve chamber, and the top interval of seat shell is provided with first opening, second opening and the third opening that lets in the conversion valve chamber, first opening is located the upside of intake pipe, the third opening is located the upside of outlet duct, be provided with in the conversion valve chamber and be used for making intake pipe and first opening form closed circuit, second opening and third opening form closed circuit and convert into the conversion valve body that first opening and second opening formed closed circuit, third opening and outlet duct formed closed circuit.
Furthermore, the switching valve body comprises a box body arranged in the switching valve cavity, a first connecting port communicated with the third through port and a second connecting port communicated with the second through port are arranged on a top plate of the box body, and a toggle handle which penetrates out of the seat shell and enables the second connecting port to be communicated with the first through port and the first connecting port to be communicated with the second through port after rotation is fixed on the upper side of the front portion of the box body.
Furthermore, the lower end of the air outlet pipe is covered with a bottom plate, air outlets are formed in the side wall of the middle of the air outlet pipe at intervals along the circumferential direction, and a piston capable of elastically lifting and descending for opening and closing the air outlets is arranged in the air outlet pipe.
Furthermore, the seat shell is formed by buckling an upper cover and a lower sealing cover.
Compared with the prior art, the utility model has the advantages of it is following: the conversion device has a compact structure, is convenient to realize the conversion of the air flow channel, can complete the conversion of the air circulation channel without the reverse rotation of the exhaust fan, and is convenient to operate and use.

fig. 2 is an exploded view of the present invention;
fig. 3 is a schematic structural diagram of the switching valve body of the present invention.
Detailed Description
In order to make the aforementioned features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below, but the present invention is not limited thereto.
Refer to fig. 1 to 3
The utility model provides a be applied to air flow conversion equipment of dust catcher, includes a housing 30, be provided with conversion valve chamber 31 in the housing, the bottom of housing is provided with intake pipe 32 and outlet duct 33 that are linked together with the conversion valve chamber, and the top interval of housing is provided with first opening 34, second opening 35 and the third opening 36 that lets in the conversion valve chamber, first opening is located the upside of intake pipe, the third opening is located the upside of outlet duct, be provided with in the conversion valve chamber and be used for making intake pipe and first opening form closed circuit, second opening and third opening form closed circuit and convert into first opening and second opening and form closed circuit, third opening and outlet duct and form the conversion valve body 37 of closed circuit.
In this embodiment, the switching valve body includes a waist-shaped box 371 disposed in the switching valve cavity, a first connection port 372 communicated with the third connection port and a second connection port 373 communicated with the second connection port are disposed on a top plate of the box, a toggle handle 374 penetrating out of the seat shell is fixed on an upper side of a front portion of the box, and after the toggle handle rotates, the second connection port is communicated with the first connection port and the first connection port is communicated with the second connection port, so as to switch the air circulation channel.
In this embodiment, the opening and closing of the air outlet pipe are controlled better, the bottom end of the air outlet pipe is covered with a bottom plate, air outlets 331 are circumferentially arranged on the side wall of the middle part of the air outlet pipe at intervals, a piston capable of elastically lifting and closing the air outlets is arranged in the air outlet pipe, and the piston elastically lifts and falls through a spring 332.
In this embodiment, the housing is formed by an upper cover 38 and a lower cover 39 that are engaged to form a switching valve chamber therebetween.
The working principle is as follows: the device is arranged at the upper end of the filter vat, the air inlet pipe and the air outlet pipe respectively extend into the filter element in the filter vat, the first port is connected with the air inlet end of the air pump, and the third port is connected with the air outlet end of the air pump. When the air filter is used, the handle is stirred leftwards, so that the air inlet pipe and the first through opening form a closed loop, the second through opening and the third through opening form a closed loop, and further, an air circulation channel is input from a dust inlet of the filter barrel, passes through the filter element, the air inlet pipe, the first through opening, an air inlet end of the air pump, an air outlet end of the air pump and the third through opening and is output from the second through opening through the conversion valve body; stir the handle and stir first opening and second opening right and form closed circuit, third opening and outlet duct and form closed circuit, and then the air is exported through the outlet duct from the second opening input through conversion valve body, first opening, air extractor inlet end, air extractor end, third opening of giving vent to anger, discharges through the income dirt mouth of lauter tub again to realize the flow path of conversion air, so that realize the dust removal of filter core.
The above is only the preferred embodiment of the present invention, and all the equivalent changes and modifications made according to the claims of the present invention should be covered by the present invention.
