Utility model content
The utility model technical issues that need to address are just the defect overcoming prior art, what provide a kind of dark duct-type hearing aids wears fixed structure, it can make hearing aids and the tight comfortable laminating of duct fix by inflating rubber ring, and the position of inflating rubber ring is regulated by adjustable slide construction, the demand of the user of different duct size can be met to greatest extent, improve property easy to use and the fixed effect of hearing aids.
For solving the problem, the utility model adopts following technical scheme: a kind of dark duct-type hearing aids wear fixed structure, this fixed structure is arranged on the housing exterior walls of hearing aids, housing is horizontally disposed cylindrical, the diameter smooth-going increase from left to right of housing, the left end of housing is elastic caoutchouc head, is provided with loud speaker in elastic caoutchouc head, middle part and the right part of housing are provided with circuit board, and the right flank of housing is backplate;
Wear fixed structure and comprise the thread bush being arranged on housing central section and right part periphery, the diameter smooth-going increase from left to right of thread bush; The periphery surface cover of thread bush is connected to the sliding sleeve that can be slidably matched with screwed pipe, and the periphery of sliding sleeve is fixed by socket several inflating rubber rings be set up in parallel, and two adjacent inflating rubber rings are communicated with by breather pipe; Inflating rubber ring can be inflated and reach different diameter, meets the fixed demand of duct; Further, the adjustment of sliding sleeve left rotation and right rotation, relative to the position of thread bush, also can adjust the diameter of sliding sleeve, meet the installation requirements of different size duct.
The inflating rubber ring of low order end is communicated with by the control valve of elastic telescopic pipe with backplate right flank, and control valve is communicated with inflatable ball by loading line, and loading line is provided with vent valve, and the pipeline between vent valve and inflatable ball is provided with unidirectional valve.Inflatable ball is the inflation of inflating rubber ring, and control valve keeps the gas tightness in inflating rubber ring.
Preferably, the inside circumference of thread bush and housing exterior walls are connected to one structure; The periphery face of thread bush is provided with screw thread, and sliding sleeve medial surface is provided with the screw thread with the threaded engagement of thread bush; Sliding sleeve is elastic caoutchouc sliding sleeve.
Preferably, control valve and loading line removably connect.After inflation completes, conveniently can go to write gas-filled tube and inflatable ball, guarantee the result of use of hearing aids the best.
Preferably, sliding sleeve outer wall is evenly equipped with 4 inflating rubber rings, the diameter of inflating rubber ring increases successively from left to right.
The using method wearing fixed structure of the dark duct-type hearing aids of the utility model is:
When wearing, according to age and the body size of user, adjust the position slided on thread bush, to adjust the diameter of inflating rubber ring; Then hearing aids is sent in duct by hand-held backplate, by inflatable ball and loading line, control valve is inflated, thus inflating rubber ring is inflated and fits fixing with ear canal wall, then taken off from control valve by loading line, control valve makes the air seal of inflating rubber ring; When taking off after using, discharged by the gas in inflating rubber ring by control valve, hearing aids takes out by hand-held backplate.
Advantage of the present utility model and beneficial effect are:
The dark duct-type hearing aids of the utility model wear fixed structure, by inflating rubber ring, hearing aids and the tight comfortable laminating of duct are fixed, and regulated the position of inflating rubber ring by adjustable slide construction, the demand of the user of different duct size can be met to greatest extent;
The dark duct-type hearing aids of the utility model wear fixed structure, by the size of sliding sleeve and thread bush adjustment inflating rubber ring, achieve and adjust operation easily, there is high convenience and practicality;
The dark duct-type hearing aids of the utility model wear fixed structure, adopt multiple inflating rubber ring be set up in parallel, and its diameter is maximum from left to right, meets the size variation structure in duct, can it stable be fixed in duct, improve property easy to use and the fixed effect of hearing aids.
