Embodiment 1
As depicted in figs. 1 and 2, the range hood filter screen in the present embodiment is mounted in range hood, is specifically mounted on
Between the guide ring 91 and spiral case 93 of range hood, play the role of an oil stain intercepting and filtering.
There is according to the range hood filter screen in the present embodiment the mesh 33 passed through for oil smoke as shown in figs. 3 to 9,
Range hood filter screen include can mutually activity setting the first strainer monomer 10 and the second strainer monomer 20, the first strainer monomer
Several first subnets hole is formed on 10, and several second subnets hole, and the first strainer monomer are formed on the second strainer monomer 20
10 and second form puncture protrusion 35 towards another strainer monomer protrusion on strainer monomer 20, wherein the first strainer list
Body 10 and the second strainer monomer 20, which have, corresponding makes the first subnet hole dock the filtering to form mesh 33 with the second subnet hole
Operating position and mutual dislocation to puncture the broken block plug working position that protrusion 35 punctures the first subnet hole and the second subnet hole
It sets.There is the first strainer monomer 10 and the second strainer monomer 20 by setting range hood filter screen, and in the first strainer monomer
10 and second form puncture protrusion 35 towards another strainer monomer protrusion on strainer monomer 20, so that in the mistake of filter screen
Operating position is filtered, the first subnet hole docks to be formed convenient for oil smoke through mesh 33 with the second subnet hole, and in the broken of filter screen
Operating position is blocked, the first subnet hole and/or the second subnet hole can be punctured by puncturing protrusion 35, and then can puncture filter screen mesh 33
On greasy dirt, alleviate blocking of the greasy dirt on mesh 33, improve the smoke absorption effect of range hood.
In a variant embodiment of the present embodiment, the difference from embodiment 1 is that only in the first strainer monomer 10
On form puncture protrusion 35 towards the protrusion of the second strainer monomer 20, can equally puncture the greasy dirt on filter screen mesh 33, subtract
Light blocking of the greasy dirt on mesh 33, realizes the smoke absorption effect for promoting range hood.
In another variant embodiment of the present embodiment, the difference from embodiment 1 is that only in the second strainer monomer
The puncture protrusion 35 towards 10 protrusion of the first strainer monomer is formed on 20, can equally puncture the greasy dirt on filter screen mesh 33,
Blocking of the greasy dirt on mesh 33 is alleviated, realizes the smoke absorption effect for promoting range hood.
With further reference to Fig. 4 and Fig. 7, the mesh 33 in the present embodiment is made of the first subnet hole and the second subnet hole,
In the first subnet hole be staggered to form by the support rod 31 on the first strainer monomer 10, the second subnet hole is by the second strainer monomer 20
On support rod 31 be staggered to form, puncture protrusion and 35 be molded on support rod 31, so that filter screen punctures filtering in realization
While greasy dirt on net mesh 33, the excessive space of filter screen will not be occupied by puncturing protrusion 35, while have good support
Intensity, so that filter screen will be more applicable in range hood.
With further reference to Fig. 4, forms and wear on the first strainer monomer 10 and the second strainer monomer 20 in the present embodiment
Thorn protrusion 35, in the filtration position of the first strainer monomer 10 and the second strainer monomer 20, the first strainer monomer 10 and second
It is mutually nested that protrusion 35 is punctured on strainer monomer 20, so that filter screen is in filtration position, the first strainer monomer 10 and second
The two of strainer monomer 20 puncture protrusion 35 and match, and the filter screen that the first strainer monomer 10 and the second strainer monomer 20 are formed has
Good bonding strength enables filter screen to have good reliability in filtration position.Puncture protrusion 35 be specially at
Broached-tooth design of the type on the first strainer monomer 10 and/or the second strainer monomer 20, so that filter screen, which has, well abolishes mesh
The effect of 33 greasy dirts.
As shown in Figure 3 and Figure 6, the mesh 33 in the present embodiment is distributed in the circumferential direction of filter screen, in the first strainer
The broken block plug operating position of monomer 10 and the second strainer monomer 20 punctures and corresponds between protrusion 35 and mesh 33, so that mistake
Strainer has the function of good filtering greasy dirt and abolishes the function of 33 greasy dirt of mesh.
Embodiment 2
The present embodiment additionally provides a kind of range hood, including range hood filter screen as described above, and then above-mentioned reality
Advantage possessed by range hood filter screen in example is applied, the range hood in the present embodiment should also have, and details are not described herein.
With further reference to Fig. 1 and Fig. 2, range hood further includes power device, and power device includes for installing the first filter
The main motor 40 of net monomer 10, and the auxiliary motor 50 for installing the second strainer monomer 20.It is main and then when range hood starting
Motor 40 and auxiliary motor 50 start that rotation speed is consistent, and main motor 40 drives the first strainer monomer 10 by main motor shaft 41 simultaneously
Rotation, auxiliary motor 50 drive the rotation of the second strainer monomer 20, the first strainer monomer 10 and the second strainer list by auxiliary motor axis 51
Body 20 makes rotating motion to a direction simultaneously, and then increases the contact area of filter screen and oil smoke, in the filtering of filter screen
Operating position, increase filter screen blocks oily effect.
With further reference to Fig. 1 and Fig. 2, the first strainer monomer 10 in the present embodiment is removably mounted within along its axial direction
On main motor 40, power device further includes push-rod electric machine 60, and push-rod electric machine 60 can push the first strainer monomer 10 along its axial direction side
To movement, and then when having served as sieve meshes 33 and blocking, main motor 40 stops, and push-rod electric machine 60 controls push rod 61 for the first strainer list
Body 10 moves down certain distance, separates it with the second strainer monomer 20, and auxiliary motor 50 starts, and drives the rotation of the second strainer monomer 20
Turn certain angle, i.e. the first strainer monomer 10 of state so that the second strainer monomer 20 and 10 mesh 33 of the first strainer monomer are staggered
The mesh 33 of the corresponding second strainer monomer 20 of broached-tooth design, the corresponding first strainer monomer 10 of the broached-tooth design of the second strainer monomer 20
Mesh 33.Then, push-rod electric machine 60 controls push rod 61 again and the first strainer monomer 10 is moved up certain distance, at this moment, the second filter
20 sawtooth of net monomer punctures the oil film or tamper of 10 mesh 33 of the first strainer monomer, and 10 sawtooth of the first strainer monomer punctures
The oil film or tamper of two strainer monomers, 20 mesh 33, after completing broken block, by anti-route by the second strainer monomer 20 and the
One strainer monomer 10, which returns, punctures raised 35 mutually nested states, then is worked normally.So circulation, it is anti-blocking to realize
Plug.
Preferably, range hood further includes the supporting structure being arranged between filter screen and power device, supporting structure packet
