Specific implementation mode

Before the utility model is described in detail, it is noted that in the following description content, similar component, portion Position is indicated with being identically numbered.

Refering to fig. 1 and shown in Fig. 2, a kind of preposition mistake for gas-filtering device that the utility model first embodiment is provided Filter is mainly made of a shell 10 and one unit 20 that draws water, wherein：

The shell 10, the second filter chamber 12 and one with one first filter chamber 11, one with first filter chamber 11 adjoining It is abutted with first filter chamber 12 and is located at 12 top of the second filter chamber and the sink 13 to contain water 91.

There is an air inlet 111, one to be communicated with second filter chamber 12 and be less than the air inlet 111 for first filter chamber 11 Communication port 112, one less than the communication port 112 and to contain the water storage portion 113, one of the water 91 communicated with the sink 13 and height Be connected in the guidance part 115 of 114 lower section of the water outlet in the water outlet 114 and one of the air inlet 111, the guidance part 115 to The water 91 flowed out by the water outlet 114 is guided, to form a water curtain 116 for covering the communication port 112；It, should in the present embodiment The guidance part 115 of first filter chamber 11 have one be connected in 114 lower section of the water outlet and tilt down inclined guide section 115A, And one connect the inclined guide section 115A and extend towards water storage portion 113 and the extension lead segment 115B of the corresponding air inlet 111, So that by the water 91 that the water outlet 114 flows out be able to along the inclined guide section 115A and extend lead segment 115B fair currents and It descends and forms the water curtain 116.

Second filter chamber 12 have one higher than the communication port 112 the first gas outlet 121 and at least two be located at this first Filtering shelves portion 122 between gas outlet 121 and the communication port 112, respectively the filtering shelves portion 122 is in staggeredly to be spaced setting and dip down Tiltedly.

The unit 20 that draws water, the water 91 in the water storage portion 113 is evacuated to the sink 13.In the present embodiment, this draws water Unit 20 includes that the drinking-water pipe 21 and one of a connection water storage portion 113 is located at 13 top of sink and is communicated with the drinking-water pipe 21 Water-pumping motor 22, the water 91 in the water storage portion 113 is evacuated to the sink 13.The Water-pumping motor 22 has one to draw water with this The entrance 221 and one that pipe 21 connects communicates and the outlet 222 of the corresponding sink 13 with the entrance 221.Due to the unit 20 that draws water For the prior art, and its manner of execution is same as the prior art, also the emphasis of non-creation, therefore for the detailed knot of the component Structure is no longer described in detail with manner of execution.

The above is the structure of each main member of the utility model first embodiment and combinations thereof state description.As for The manner of execution of the utility model is described as follows with effect.

Need to first it illustrate, when carrying out the filtering of gas 96, gas 96 is can be by the first filter chamber 11 of the shell 10 Air inlet 111 enters, and is finally exported by the first gas outlet 121 of the second filter chamber 12 of the shell 10；In addition, the sink 13 Interior water 91 can be flowed out from the water outlet 114, and flow to the water storage portion 113 along the shape of the guidance part 115, to form one The water curtain 116 of the communication port 112 is covered, and makes the water curtain 116 be able to continue generation by the start for drawing water unit 20.

As shown in fig.2, when gas 96 enters the first filter chamber 11 by the air inlet 111 of the shell 10, the part gas Body 96 strikes the water curtain 116 in advance, at this point, dust particles larger in gas 96 can be with the gas-vapor mix in the water curtain 116 Or it dissolves and is brought away from and flow to the water storage portion 113；Secondly, when the gas 96 in the first filter chamber 11 is flowed towards the second filter chamber 12 When dynamic, since the water curtain 116 is to cover the communication port 112, that is, first filter chamber 11 is divided into the first mistake by the water curtain 116 Space 117 and the second filter space 118 are filtered, therefore, which has to pass through the water curtain 116, and passes through the water in gas 96 When curtain 116, in gas 96 larger dust particles equally can with gas-vapor mix or the decomposition in the water curtain 116 and be brought away from cocurrent To the water storage portion 113, in this way, the first time for completing the gas 96 is filtered.

And then, it is flowed out from the first gas outlet 121 when gas 96 is entered by communication port 112 in second filter chamber 12 When, due to having in second filter chamber 12 at least two 122 structures of filtering Documents Department for being staggeredly spaced setting and tilting down Design, it is thus possible to increase the circulation path of the gas 96 and provide the dust particles in gas 96 hit and blocking, such as This, will complete second of filtering of the gas 96.

Accordingly, the utility model by the structure design of the shell 10 and this draw water unit 20 by be able in first mistake A water curtain 116 for covering the communication port 112 is formed in filter chamber 11, the gas 96 to enter to air inlet 111 carries out for the first time Filtering, then by being in staggeredly interval setting and at least two filtering shelves portions 122 tilted down in the second filter chamber 12, with to connecting The gas 96 that port 112 enters carries out second and filters, and reaches and reaches best filter efficiency and generation with most easy structure The purpose of minimum resistance.

It is noted that the water curtain 116 is the completely obscured communication port 112 in the utility model, therefore when the first mistake When gas 96 in filter chamber 11 is flowed towards the second filter chamber 12, which has to pass through the water curtain 116, and also therefore this practicality is new Type is able to ensure the gas-vapor mix in the gas 96 and the water curtain 116 or dissolving, to ensure the filter efficiency of gas 96.

As shown in fig.3, a kind of fore filter for gas-filtering device that the utility model second embodiment is provided, It is equally made of shell 10 and the unit 20 that draws water, be different from the first embodiment be in：

The third filter chamber 14 that the shell 10 abuts second filter chamber 12 with more one, which passes through this First gas outlet 121 and communicated with second filter chamber 12, and with one be less than first gas outlet 121 the second gas outlet 141.Accordingly, when the gas 96 is by the first gas outlet 121 entrance third filter chamber 14 of second filter chamber 12 and by second When gas outlet 141 is discharged, when the gas 96 is discharged by second gas outlet 141, the flow path of the gas 96 must be bent One angle, in this way, the dust particles in gas 96 can be influenced with gravity by inertia and be detached, to increase filter efficiency.

As shown in fig.4, a kind of fore filter for gas-filtering device that the utility model 3rd embodiment is provided, It is equally made of shell 10 and the unit 20 that draws water, with second embodiment difference be in：

The 4th filter chamber 15 that wherein shell 10 abuts the third filter chamber 14 with more one, the 4th filter chamber 15 are logical The third outlet crossed second gas outlet 141 and communicated with the third filter chamber 14, and be higher than second gas outlet 141 with one Mouth 151.Accordingly, when the gas 96 the 4th filter chamber 15 entered by the second gas outlet 141 of the third filter chamber 14 and by the When three gas outlets 151 are discharged, when the gas 96 is discharged by the third gas outlet 151, the flow path of the gas 96 must be curved An angle is rolled over, in this way, the dust particles in gas 96 can be influenced with gravity by inertia and be detached, to increase filter efficiency.

As shown in fig.5, a kind of fore filter for gas-filtering device that the utility model fourth embodiment is provided, It is equally made of shell 10 and the unit 20 that draws water, be different from the third embodiment be in：

The 4th gas outlet 152 that 4th filter chamber 15 is less than the third gas outlet 151 with more one, to reach another reality Apply state.
