Abstract
The utility model discloses a dab membrane switch device for dust catcher, including PCB, the support, PCB is soft PCB strip, soft PCB strip is fixed to be installed on the support, soft PCB strip facial make -up is equipped with and dabs membrane switch soft PCB strip still is equipped with soft silica gel strip outward. The utility model discloses a combination of soft PCB strip of rational utilization and soft silica gel strip for collision integration, the collision sensitivity fast reaction that has improved the dust catcher so greatly, also greatly reduced traditional structure collision noise, avoided colliding among the the walking process the reactionless condition, the interference that protection PCB did not receive dust, steam and high temperature can be played with the such structure of the soft silica gel strip soft PCB strip of parcel simultaneously, the life who dabs membrane switch has been guaranteed.
Description
Technical field
The utility model relates to dust collector device field, is specifically related to a kind ofly touch membrane switch device for dust catcher.
Background technology
The operation principle of dust catcher is motor of dust collector High Rotation Speed; air is sucked from suction inlet; dirt case is made to produce certain vacuum; dust enters the bag dust filter in dirt case by scrubbing brush, adapter, handle, flexible pipe, main suction pipe; dust is left in bag dust filter; air after filtration enters motor through one deck filter again; this layer of filter prevents the dirt bag dust that breaks from sucking one protective barrier of motor; the air entering motor flows out through motor; because in motor operation, carbon brush constantly weares and teares, add again before therefore flowing out dust catcher and filtered together.At present, the crash device of existing dust catcher mainly adopts a mechanical arm of force and microswitch, when collision is exactly there will be the mechanical arm of force and microswitch to collide generation noise, or cause reactionless, mechanical arm of force accuracy cannot be avoided when carrying out collision and doing, cause collision to postpone, collision sensitivity is unreliable, and in use for some time, mechanical arm of force serious wear brings collision sensitivity to decline, and affects the experience of user.
Utility model content
For the problems referred to above, the utility model aim to provide a kind of structure simple and fast response time, efficiency high touch membrane switch device for dust catcher.
For realizing this technical purpose, scheme of the present utility model is: a kind ofly touch membrane switch device for dust catcher, comprise PCB, support, described PCB is soft PCB bar, described soft PCB bar is installed on described support, described soft PCB bar is equiped with and touches thin film switch, be also provided with soft silica gel bar outward at described soft PCB bar.
As preferably, touch thin film switch for the ease of can fully contact, described in touch thin film switch and be provided with and touch a little, described in touch be some cylindrical structure, described in touch thin film switch horizontal.
As preferably, touching thin film switch to protect, increasing service life, described soft silica gel bar comprises contact and strikes the post, described in the height of striking the post higher than the described height touching thin film switch, and described in the internal diameter of striking the post larger than the described diameter touched a little.
As preferably, in order to better fix PCB, the two ends of described support are provided with stent strut, because PCB device is on support, just can be completely fixed PCB, therefore on support, installs stent strut by fixed support, then are screwed the switch place being connected to dust catcher.
As preferably, in order to better protect PCB, the both sides on described soft PCB bar are provided with snap close; the both sides of described soft silica gel bar are also provided with bonnet lock hole; in order to ensure, in the service life of dust catcher switch in the course of the work, to wrap up completely PCB with soft silica gel bar, isolation dust.
The utility model passes through the combination of the soft PCB bar of Appropriate application and soft silica gel bar, make collision integration, substantially increase the collision sensitivity fast reaction of dust catcher like this, also greatly reduce traditional structure collision noise, avoid in walking process and collide reactionless situation; Wrap up the such structure of soft PCB bar with soft silica gel bar simultaneously and can play protection PCB not by the interference of dust, steam and high temperature, ensure that the service life of touching thin film switch.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is structure for amplifying schematic diagram of the present utility model;
Fig. 3 is partial enlargement structural representation of the present utility model.
Wherein: 1. support, 2. soft PCB bar, 3. touches thin film switch, 4. soft silica gel bar, 11. snap closes, and 21. touch a little, 31. bonnet lock holes, 32. contacts, and 33. strike the post, 41. stent struts.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 1 to Figure 3, best specific embodiment of the present utility model a kind of touches membrane switch device for dust catcher, comprise PCB, support 4, described PCB is soft PCB bar 1, described soft PCB bar 1 is installed on described support 4, described soft PCB bar 1 is equiped with and touches thin film switch 2, outside described soft PCB bar 1, be also provided with soft silica gel bar 3.
As preferably, touch thin film switch 2 for the ease of can fully contact, described in touch thin film switch 2 and be provided with and touch a little 21, described in touch 21 be some cylindrical structure, described in touch thin film switch 3 horizontal.
As preferably; touching thin film switch 2 to protect, increasing service life, described soft silica gel bar 4 comprises contact 32 and strikes the post 33; described strike the post 33 height higher than the described height touching thin film switch 2, and described in strike the post 33 internal diameter than described touch a little 21 diameter large.
As preferably, in order to better fix PCB, the two ends of described support 4 are provided with stent strut 41, because PCB device is on support, just can be completely fixed PCB by fixed support, therefore on support, install stent strut, then be screwed the switch place being connected to dust catcher.
As preferably, in order to better protect PCB, the both sides on described soft PCB bar 1 are provided with snap close 11; the both sides of described soft silica gel bar 4 are also provided with bonnet lock hole 41; in order to ensure, in the service life of dust catcher switch in the course of the work, to wrap up completely PCB with soft silica gel bar, isolation dust.
The utility model passes through the combination of the soft PCB bar of Appropriate application and soft silica gel bar, make collision integration, substantially increase the collision sensitivity fast reaction of dust catcher like this, also greatly reduce traditional structure collision noise, avoid in walking process and collide reactionless situation; Wrap up the such structure of soft PCB bar with soft silica gel bar simultaneously and can play protection PCB not by the interference of dust, steam and high temperature, ensure that the service life of touching thin film switch.
The above; be only preferred embodiment of the present utility model; not in order to limit the utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solutions of the utility model.
