In other words, user to cylinder block set 1 when dismounting pre-flock device assembly 2, without directly touching filter assemblies 22 with hand, In other words, filter assemblies 22 are not an exposure to outer, so as to avoid secondary pollution.It says more bluntly, it is assumed that prefilter Not including prefilter box 21 and when only including filter assemblies 22, example as shown in Figure 3 is needing to take filter assemblies 22 component 2 When going out to clear up, user needs first to open the first lid 114 on casing 11, so that filter assemblies 22 is revealed, then directly Filter assemblies 22 are taken out out of upper mounting portion 1121 installation cavity 1123 with hand, and filter assemblies 22 are transplanted on pond or rubbish At rubbish bucket clear up, in this way, due to filter assemblies 22 be directly exposed to it is mobile in environment, so filter assemblies 22 move During, the fouls such as dust adhered to thereon are inevitably fallen in the environment, to will result in secondary pollution.

However, when pre-flock device assembly 2 includes containing the prefilter box 21 of filter assemblies 22, show as shown in figures s-11 Example only need to be removed prefilter box 21, then by pre-flock when user, which needs to take out filter assemblies 22, to clear up from casing 11 Device box 21 is transplanted at pond or dustbin, then prefilter box 21 is opened taking-up filter assemblies 22 and is cleared up, in this way, Since prefilter box 21 is enclosed box body, the problem of will not occurring to fall dust into environment during it is transferred, from And secondary pollution can be effectively prevented from.

In addition, when filter assemblies 22 include multiple prefilters, such as level-one prefilter 221 and when two level prefilter 222, if Pre-flock device assembly 2 does not include prefilter box 21, example as Figure 3-Figure 4, during taking out filter assemblies 22, it is necessary to Multiple taking-up action, the action for acting, individually taking out two level prefilter 222 for such as individually taking out level-one prefilter 221, action are numerous It is trivial, waste time.And when pre-flock device assembly 2 includes accommodating the prefilter box 21 of filter assemblies 22, show as shown in figures s-11 Example, if you need to remove filter assemblies 22, it is only necessary to the primary action for removing prefilter box 21, you can make level-one prefilter 221 and two Grade prefilter 222 is removed together, to simplify operation.

Similarly, if pre-flock device assembly 2 does not include prefilter box 21, example as Figure 3-Figure 4, in installation filter assemblies During 22, it is also desirable to the acting of multiple installation action, such as separately installed level-one prefilter 221, separately installed two level pre-flock The action of device 222, action is cumbersome, wastes time, and level-one prefilter 221 and two level prefilter 222 are easy to be anti-loaded.And work as Pre-flock device assembly 2 includes example as shown in figures s-11, if you need to install filtering group when accommodating the prefilter box 21 of filter assemblies 22 Part 22, it is only necessary to the action of once mounting prefilter box 21, you can make level-one prefilter 221 and two level prefilter 222 together by Installation avoids level-one prefilter 221 and two level prefilter 222 by anti-loaded problem to simplify operation.In order to more clearly Illustrating how can be more time saving and energy saving, carries out comparative illustration by taking the application scenarios of Fig. 3 and Fig. 8 as an example below.

In the example of fig. 3, if you need to clear up filter assemblies 22, user need a hand go to execute the opening of the first lid 114, Three taking-up of level-one prefilter 221, the taking-up of two level prefilter 222 actions, the implementation procedure that the other hand is acted at these three The whole grip cylinder block set 1 of middle needs, since these three actions take longer, the time of another hand grip cylinder block set 1 It is just longer, cause the operation of user more laborious.After clearing up level-one prefilter 221 and two level prefilter 222, user is also Need a hand grip cylinder block set 1, another hand execute the installation of two level prefilter 222, the installation of level-one prefilter 221, Three actions of installation of first lid 114, operation are also relatively complicated so that user still needs to hold cylinder block set 1, operating cost for a long time Power.

And in the example of fig. 8, during pre-flock device assembly 2 is dismounted on casing 11, one hand grip machine of user Body component 1, another hand only need an action for removing prefilter box 21, and process is very of short duration, user is very laborsaving, after Continuous user can put down cylinder block set 1, and small and exquisite prefilter box 21 is taken cleaning position, then easily dismantles prefilter box 21, it takes out filter assemblies 22 and is cleared up, after cleaning, filter assemblies 22 are reinstalled into prefilter box 21, then by prefilter box 21 It brings back at cylinder block set 1, a hand grip cylinder block set 1, another hand only needs one prefilter box 21 is put in back body The action of component 1, operation are very quick, laborsaving.
