Ultrasound atomizer
This utility model relates to a kind of medical mouthful and inhales the formula ultrasound atomizer, belongs to medical apparatus and instruments.
Medical ultrasonic atomizer is that a kind of 1.7 mhz frequency ultrasound wave that utilize intensify medicinal liquid in the liquid medicine cup, make it be atomized into fine mist, under the effect of suitable air-flow, the medicinal liquid droplet is from the fog outlet of atomizing cup, discharge through sending the mist corrugated tube, patient's ripple mouth of pipe of only need dehiscing to aim at just can suck pulmonary with the medicinal liquid droplet, reach therapeutic effect.But wind passage mouth and fog outlet lean on very closely in the cup of prior art ultrasound atomizer, and air-flow turns in fog outlet after entering cup by wind passage mouth soon, and the droplet that can take away is less, influences the fog-supplying amount of unit interval; And atomizing cup and compressing of liquid medicine cup all adopt the briquetting compacted form, changes liquid and clean all inconveniently, and structure is loaded down with trivial details, and this sends the bending arbitrarily of mist corrugated tube, compression and stretching outside, is not easy to patient and uses, and is not easy to collect.
The purpose of this utility model provide a kind ofly go out that the mist rate is higher, liquid medicine cup and atomized cover cup tear open easy, but send the bending of mist corrugated tube flexible ultrasound atomizer.
In order to achieve the above object, this utility model is achieved in that a kind of ultrasound atomizer, comprise supersonic generator, fan and air-duct apparatus, liquid medicine cup, atomizing cup, send mist corrugated tube, electric apparatus control apparatus and casing, be provided with baffle plate between described atomizing cup endogenous wind road junction and the fog outlet, baffle plate stretches into the liquid medicine cup middle part, and the both sides of the edge of baffle plate and liquid medicine cup group match; Described liquid medicine cup is shelved on the casing with the flange location, the relative driving fit of flange of atomizing cup with the liquid medicine cup flange, hidden discount cooperation embedding mutually with same quantity in the groove of 3 to 4 wedge-like dops of atomizing cup bead and casing, wedge-like dop and hidden discount wedging when cup rotates make the atomizing cup be pressed in liquid medicine cup on the casing tightly by flange; The described ripple indentation that send the mist corrugated tube, two straight flanges of each sawtooth ripple and tooth depth angle are respectively 31 ° and 41 °.
The utlity model has following advantage: be provided with baffle plate in (1) atomizing cup wind passage mouth and fog outlet are separated, air-flow must be walked around baffle plate and discharge, track route lengthening in container, and the droplet of taking away increases, and can improve condensation rate 1~1.5 ml/min; (2) because the atomizing cup adopts the wedge-like dop to cooperate the rotation wedging with the hidden discount of casing, simplify the structure, not only make cup and convenient, only need that cup is turned over a low-angle and get final product, and make instrument cover more succinct, lucid and lively with the liquid medicine cup mounting or dismounting; (3) send the mist corrugated tube to adopt the zigzag ripple, individual potential energy limit is arranged between the stretching of each sawtooth bellows segment and the compressive state, external force need be applied and state can be changed, make arbitrarily bending of corrugated tube, flexible, user is as long as transfer to proper height by own demand with corrugated tube, need not to hold with hand steered, inspiratory therapeutic comfily just, the time spent can not contract corrugated tube to the shortest, puts into the sky liquid medicine cup, covers cup, not only health but also be not easy to lose, short as far as possible in addition ripple pipeline can reduce the pipeline loss of droplet air-flow again, correspondingly improves the nebulae inhalation effect.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the cutaway view of this utility model ultrasound atomizer.
Fig. 2 is the vertical view that the wedge-like dop of this utility model ultrasound atomizer atomizing cup cooperates with the casing hidden discount.
Fig. 3 is the expansion cutaway view of Fig. 2.
Fig. 4 and Fig. 5 are that this utility model ultrasound atomizer send mist corrugated tube sawtooth corrugated stretch and compressive state sketch map.
Ultrasound atomizer shown in Figure 1 by supersonic generator 1, liquid medicine cup 2, atomizing cup 4, send mist corrugated tube 5, fan and air-duct apparatus 6, casing 7 and electric apparatus control apparatus 8 to form, between the wind passage mouth of the cup 4 that atomizes and the fog outlet baffle plate 3 is arranged.The arc thin film that the ultrasound wave that instrument when work supersonic generator 1 produces sees through liquid medicine cup 2 bottoms intensifies the medicinal liquid in the liquid medicine cup, make its atomizing, the air-flow that fan produces enters cup through valve adjustments from the wind passage mouth of atomizing cup 4, because stopping of baffle plate 3, after air-flow need be walked around baffle plate downwards, upwards to fog outlet, air-flow was taken away the medicinal liquid droplet around here again, through sending mist corrugated tube 5 to send into patient's mouth, suck pulmonary.
The wedge-like dop 9 of Fig. 2, atomizing cup bead shown in Figure 3 matches with the hidden discount 10 of casing, and when cup rotated, the wedge-like dop was tightly wedged in the hidden discount 10, and cup is pressed in liquid medicine cup on the casing tightly by wedge-like dop and hidden discount.
Fig. 4 and mist corrugated tube sawtooth corrugated stretch and the compressive state sent shown in Figure 5, between these two stable shapes, a potential energy limit (dead point) is arranged, promptly along with the sawtooth waveforms minor face by left side position (position promptly stretches) when rotate the upright position, the external diameter of its rotation dish shape face constantly increases, and internal diameter constantly reduces, thereby causes that the outer ring is stretched, inner ring is compressed, stress constantly increases, when minor face goes to the upright position, and the stress maximum, cross this point when being rotated further, stress discharges rapidly, and minor face forwards right position (being compression position) to, and vice versa, change any state, must apply external force, each state has relative stability, so user can be according to own needs, the shape of mist corrugated tube is sent in adjustment, and needn't hand corrugated tube.
