In addition, because porous stock solution medium 300 sets up in the chamber 9 of acceping between stock solution chamber 8 and atomizing chamber 7, the volume of acceping chamber 9 is less than the volume of stock solution chamber 8, fill porous stock solution medium 300 in acceping chamber 9, can reduce the stock solution proportion of porous stock solution medium 300 and the volume and/or the radial dimension of porous stock solution medium 300, the realization reduces the osmotic resistance of porous stock solution medium 300, can show the volume of remaining of atomizing liquid in the reduction porous stock solution medium 300, make the atomizing liquid can be fully atomized, thereby can effectively improve the utilization ratio of atomizing liquid, avoid causing too much atomizing liquid to remain extravagantly.
The embodiment of the utility model provides an atomizer, compared with the prior art, the atomizing chamber 7 that is provided with holding atomizing core 200 inside in atomizing bullet main part 100 and the stock solution chamber 8 that can store atomizing liquid to be provided with the chamber 9 of acceping of the porous stock solution medium 300 of holding between stock solution chamber 8 and atomizing chamber 7, be equipped with feed liquor hole 221 and the intercommunication of intercommunication stock solution chamber 8 and acceping chamber 9 respectively on atomizing bullet main part 100 and accept chamber 9 and atomizing chamber 7 lead liquid mouth 321. When the atomizer is used, atomized liquid in the liquid storage cavity 8 can be transmitted to the Kong Chuye medium 300 at most through the liquid inlet hole 221, and the atomized liquid is slowly and uniformly transmitted to the liquid guide port 321 through the porous liquid storage medium 300, so that the atomized liquid in the liquid storage cavity 8 can be prevented from directly flowing to the atomization cavity 7 through the liquid guide port 321, and the risk of dry burning caused by liquid leakage of the atomizer and horizontal suction of the atomizer is reduced. And, set up porous stock solution medium 300 in the chamber 9 of acceping between stock solution chamber 8 and atomizing chamber 7, reach the effect that reduces porous stock solution medium 300 stock solution proportion and osmotic resistance, can show the volume of remaining of atomizing liquid in the reduction porous stock solution medium 300 for the atomizing liquid can be fully atomized, thereby can effectively improve the utilization ratio of atomizing liquid, avoids causing too much atomizing liquid to remain extravagantly.
In some of these embodiments, the reservoir volume of the porous reservoir medium 300 is between 10% and 60% of the total reservoir volume, which is the sum of the reservoir volume of the reservoir chamber 8 and the reservoir volume of the porous reservoir medium 300. In this embodiment, set up porous stock solution medium 300 in the chamber 9 of acceping between stock solution chamber 8 and atomizing chamber 7 for porous stock solution medium 300's stock solution volume accounts for 10% ~ 60% of total stock solution volume, under the prerequisite that prevents the weeping or the suction dry combustion method phenomenon of lying, can reduce the atomizing liquid residue volume in porous stock solution medium 300 simultaneously, improves the utilization ratio of atomizing liquid. In this embodiment, the ratio of the atomized liquid in the total liquid storage amount through reducing the porous liquid storage medium 300 is reduced, and the radial size of the porous liquid storage medium 300 is reduced, so that the radial osmotic resistance of the atomized liquid can be reduced, the residual amount of the atomized liquid in the porous liquid storage medium 300 can be reduced, so that the atomized liquid in the liquid storage cavity 8 can be almost completely consumed, and the residual amount of the atomized liquid can be reduced. Further, in order to significantly reduce the residual amount of the atomized liquid in the porous liquid storage medium 300 and improve the utilization rate of the atomized liquid on the premise of preventing liquid leakage or dry burning due to lying and suction, the ratio of the stored liquid amount of the porous liquid storage medium 300 to the total stored liquid amount is preferably 20% to 30%. It should be noted that, when the ratio of the stored liquid amount of the porous liquid storage medium 300 to the total stored liquid amount is less than 10%, the liquid locking capability of the porous liquid storage medium 300 to the atomized liquid is reduced, which causes the liquid storage performance of the porous liquid storage medium 300 to be reduced, and is prone to leakage or dry burning due to horizontal suction; when the proportion that the stock solution volume of porous stock solution medium 300 accounted for total stock solution volume is greater than 60%, can obviously increase porous stock solution medium 300 osmotic resistance, cause the residual quantity of atomizing liquid more in the porous stock solution medium 300, be unfavorable for improving the utilization ratio of atomizing liquid.
Referring further to fig. 1, 3 and 4, in some embodiments, the porous liquid medium 300 fills the receiving cavity 9, and the porous liquid medium 300 covers the liquid inlet hole 221. In this embodiment, porous stock solution medium 300 is through the atomized liquid direct contact in feed liquor hole 221 and the stock solution chamber 8, because feed liquor hole 221 makes a part of porous stock solution medium 300 and the atomized liquid direct contact in the stock solution chamber 8, for in prior art directly place porous stock solution medium 300 in stock solution chamber 8 and cause porous stock solution medium 300 and atomized liquid large tracts of land contact, be favorable to leak protection liquid and reduce the volume of remaining of atomized liquid. In addition, the reduced liquid inlet hole 221 increases the flow resistance of the atomized liquid in the liquid storage cavity 8 to the porous liquid storage medium 300, makes up for the deficiency that the porous liquid storage medium 300 has reduced osmotic resistance to the atomized liquid due to the reduction of the volume and/or radial dimension of the porous liquid storage medium 300, and enables the porous liquid storage medium 300 to improve the utilization rate of the atomized liquid and the advantage of effective leakage prevention. In addition, the porous liquid storage medium 300 covers the liquid inlet hole 221, so that the flow resistance of the atomized liquid in the liquid storage cavity 8 to the porous liquid storage medium 300 is further improved, the defect that the permeation resistance of the porous liquid storage medium 300 to the atomized liquid is reduced due to the reduction of the volume and/or the radial size of the porous liquid storage medium 300 is effectively overcome, and liquid leakage is favorably prevented. It should be noted that in other embodiments, in order to compensate for the shortage that the porous storage medium 300 has smaller penetration resistance to the atomized liquid due to the reduction of the volume and/or radial dimension of the porous storage medium 300, and to enhance the liquid leakage prevention effect, the porous storage medium 300 can cover not only the liquid guide port 321, but also the liquid inlet hole 221 and the liquid guide port 321 of the porous storage medium 300.
Referring further to fig. 2, 3 and 4, in some embodiments, the receiving cavity 9 is disposed adjacent to the bottom of the liquid storage cavity 8, and the liquid inlet hole 221 is disposed adjacent to the bottom of the liquid storage cavity 8. In this embodiment, will accept the bottom setting that chamber 9 closes on stock solution chamber 8, will accept chamber 9 and set up in the bottom of stock solution chamber 8 or be close to the position of stock solution chamber 8 bottom soon for atomizing liquid in the stock solution chamber 8 can transmit to the porous stock solution medium 300 who accepts in the chamber 9 through feed liquor hole 221 steadily under the effect of self gravity. And, close on the bottom setting of stock solution chamber 8 with feed liquor hole 221, be about to feed liquor hole 221 set up in the bottom of stock solution chamber 8 or be close to the position of stock solution chamber 8 bottom, realize the low-order feed liquor for atomized liquid is whole to be transmitted to accepting porous stock solution medium 300 in the chamber 9 as far as possible in the stock solution chamber 8, is favorable to reducing the residue of atomized liquid in the atomizing chamber 7, can make atomized liquid can be by whole consumption in the atomizing chamber 7 even, thereby is favorable to improving the utilization ratio of atomized liquid.
