Referring to fig. 1, 2, 3 and 4, an embodiment of the invention provides a nozzle 10 for an atomizer 100, where the nozzle 10 includes a body 11 and a first liquid blocking portion 12. The body 11 is provided with a first air passage 111 in a penetrating manner, and the first liquid blocking portion 12 is disposed on an inner wall of the first air passage 111 and used for blocking liquid on the inner wall of the first air passage 111 from flowing into the air inlet 1111 of the first air passage 111.

It should be noted that, when the suction nozzle 10 is disposed on the atomizer 100, the first air passage 111 formed on the body 11 is communicated with the second air passage 22 inside the atomizer 100, so that the atomized air can be inhaled by the human body through the first air passage 111.

In addition, the liquid on the inner wall of the first air passage 111 may be a liquid formed by condensation of the atomized gas on the inner wall of the first air passage 111, may also be other liquids in the external environment, such as saliva or other secretions of a human body, and may also be a mixed liquid of one or more of the above liquids, which is not described herein again.

Specifically, when the mist passes through the first air passage 111, a part of the mist may be deposited on the inner wall of the first air passage 111 and condensed into liquid. When the mouthpiece 10 is inverted during use, liquid deposited on the inner walls of the first air duct 111 flows along with the inner walls of the first air duct 111. If liquid is back-filled into the atomizer 100 through the inlet 1111 of the first air passage 111, the liquid may be adsorbed onto the atomizing plate assembly 30 and even back-filled into the air pressure sensor 23 along the second air passage 22. In this case, the back-filling of the liquid will affect the normal start-up of the atomizer 100.

Based on the above situation, the first liquid blocking portion 12 is disposed on the inner wall of the first air passage 111, and when the liquid is deposited on the inner wall of the first air passage 111, the first liquid blocking portion 12 can block the liquid from flowing along the inner wall of the first air passage 111 and entering the air inlet 1111 of the first air passage 111, and further block the liquid from entering the second air passage 22 of the atomizer 100 from the air inlet 1111 of the first air passage 111.

From this, first fender liquid portion 12 can prevent effectively that the liquid of deposit on first air flue 111 inner wall from flowing into the air inlet 1111 of first air flue 111, and then prevents that liquid from backward filling into atomizer 100's second air flue 22 in, has increased the stability that the atmospheric pressure value was judged, ensures atomizer 100's normal start.

In some embodiments, the first liquid blocking portion 12 protrudes from an inner wall of the first air channel 111, and forms a liquid blocking space 13 with the inner wall of the first air channel 111.

The first liquid blocking portion 12 protruding from the inner wall of the first air channel 111 can block the flow path of the liquid deposited on the inner wall of the first air channel 111, and when the liquid flows to the position of the first liquid blocking portion 12 along the inner wall of the first air channel 111, the liquid cannot flow to the air inlet 1111 of the first air channel 111 due to the blocking of the first liquid blocking portion 12. Therefore, the liquid can be effectively prevented from flowing into the air inlet 1111 of the first air passage 111, and the liquid can be prevented from entering the second air passage 22 of the atomizer 100 through the air inlet 1111 of the first air passage 111, so that the normal starting of the atomizer 100 is ensured.

It is understood that in some other embodiments, the first liquid blocking portion 12 may be provided in other structures. For example, the first liquid blocking portion 12 may be configured as a groove structure opened on the inner wall of the first gas channel 111, and thus, the first liquid blocking portion 12 can also form a block to the flow path of the liquid deposited on the inner wall of the first gas channel 111. When liquid flows to first fender liquid portion 12 position along first gas channel 111 inner wall, liquid gets into the groove structure that first fender liquid portion 12 formed, and groove structure can play certain storage effect to liquid, avoids liquid to continue to flow along first gas channel 111 inner wall. Thereby, the liquid can be prevented from flowing into the air inlet 1111 of the first air passage 111 and further into the second air passage 22 of the nebulizer 100.

Based on this, the first liquid blocking portion 12 only needs to be configured to be a structure capable of blocking a flow path of the liquid deposited on the inner wall of the first gas channel 111, and details thereof are not described here.

Referring to fig. 3 and 5, in some embodiments, the first liquid blocking portion 12 protrudes and is disposed around an inner wall of the first air channel 111, and forms a liquid blocking space 13 around the first air channel 111 with the inner wall of the first air channel 111. The first liquid blocking portion 12 is provided with an air passing hole 121 communicating an air inlet 1111 and an air outlet 1112 of the first air passage 111.

Specifically, the first liquid blocking portion 12 is protruded on an inner wall of the first air passage 111, and surrounds the inner wall of the first air passage 111, that is, the first liquid blocking portion 12 is configured as an annular structure protruded on the inner wall of the first air passage 111. Therefore, the first liquid blocking portion 12 forms a continuous ring shape in the first air passage 111, and can completely block liquid on each position on the inner wall of the first air passage 111 along the circumferential direction of the first air passage 111. Compared with a discontinuous annular structure formed on the inner wall of the first air channel 111, the continuous first liquid blocking part 12 can block liquid on the inner wall of the first air channel 111 more comprehensively, and blocking efficiency is improved.

Furthermore, the air passing hole 121 is opened at the middle position of the first liquid blocking part 12, and the air passing hole 121 can ensure that atomized air smoothly enters from the air inlet 1111 of the first air channel 111 and is inhaled by the human body from the air outlet 1112 of the first air channel 111.

It is understood that, in some other embodiments, the first liquid blocking portion 12 may also be protruded on the inner wall of the first air channel 111, and form a discontinuous ring structure around the inner wall of the first air channel 111. At this time, due to the discontinuity of the first liquid blocking portion 12, a few gaps are naturally formed in the first liquid blocking portion 12. Therefore, the air inlet 1111 and the air outlet 1112 of the first air channel 111 can be communicated through a plurality of naturally formed gaps without additionally arranging the air passing hole 121 on the first liquid blocking part 12.

In some embodiments, the first liquid blocking portion 12 includes a blocking section 122 and a communicating section 123, the blocking section 122 is disposed on the inner wall of the first air passage 111 in a surrounding manner, the communicating section 123 is formed in a protruding manner at an end of the blocking section 122 away from the inner wall of the first air passage 111, and the middle of the communicating section 123 is opened with the air passing hole 121. The communicating section 123 and the blocking section 122 define a liquid blocking space 13, and the liquid blocking space 13 is a liquid blocking groove with an opening facing the air outlet 1112 in the first air channel 111.

When the liquid deposited on the inner wall of the first air channel 111 flows from the air outlet 1112 of the first air channel 111 to the air inlet 1111, the liquid blocking space 13 can achieve the storage and blocking of the liquid, and thus the blocking effect of the liquid can be further improved.

In some embodiments, the body 11 includes a main body 112 with a first air passage 111 and a shoulder 113 protruding from the outer periphery of the main body 112, and the shoulder 113 has at least one air exhaust hole 1131 communicating the first air passage 111 with the outside.

Specifically, when the mouthpiece 10 is used by being placed on the atomizer 100, the human body has two processes of exhalation and inhalation. When a human body inhales, the air pressure sensor 23 detects the air pressure change in the second air passage 22, so that the atomizer 100 is started and works to realize the atomization process.

When the human body exhales, the exhaled air affects not only the air pressure in the second air passage 22, but also the detection result of the air pressure sensor 23. Also, exhaled air may contain some liquid that would interfere with proper activation of the nebulizer 100 if it entered the nebulizer blade assembly 30 or air pressure sensor 23 in the second airway 22.

Therefore, the exhalation vent 1131 communicating the first air duct 111 with the outside is disposed on the body 11, so that the exhaled air can be directly exhausted from the first air duct 111 to the outside through the exhalation vent 1131, and cannot enter the atomizer 100 through the second air duct 22, thereby ensuring normal starting of the atomizer 100.

Further, the axial direction of the at least one exhalation vent 1131 is at an angle less than 90 degrees with respect to the axial direction of the first air duct 111. It can be understood that the included angle smaller than 90 can effectively prevent the exhalation vent 1131 from being covered in the use process, and improve the ventilation reliability of the exhalation vent 1131.

More preferably, the axial direction of each exhalation port 1131 is parallel to the axial direction of the first air duct 111. Therefore, the gas in the first air passage 111 can be more conveniently discharged from the exhalation port 1131, so that the gas in the first air passage 111 can be more smoothly discharged.

Referring to fig. 3 and 6, in some embodiments, the suction nozzle 10 includes at least two guiding members 14, and each guiding member 14 is disposed on a side of the first liquid-blocking portion 12 facing the air inlet 1111 and spaced along a circumferential direction of the first air channel 111. Wherein, a guide channel 141 is formed between every two adjacent guide pieces 14, the air inlet end of each guide channel 141 is communicated with the first air channel 111, and the air outlet end is communicated with the exhalation port 1131.

When the first liquid blocking portion 12 is disposed in the first air channel 111, the first liquid blocking portion 12 divides the first air channel 111 into two sub air channels along a direction from the air inlet 1111 of the first air channel 111 to the air outlet 1112. Each guide 14 is disposed in the sub-air passage on the side of the first liquid blocking portion 12 facing the air inlet 1111, and during the air suction process, each guide 14 can block the atomized air entering the sub-air passage provided with the guide 14 from the second air passage 22 to a certain extent, so that the atomized air can smoothly enter the other sub-air passage from the air passing hole 121 and be inhaled by the human body. This can prevent the discharge of the mist from the exhalation port 1131 as much as possible, thereby reducing the atomization effect of the nebulizer 100.

In addition, during the exhalation process, the guide channels 141 formed between the guide pieces 14 can enable the exhaled air to be smoothly discharged from the exhalation port 1131, and the exhaled air is prevented from entering the second air duct 22 and affecting the use effect of the nebulizer 100.

Further, as shown in fig. 7, each guide 14 is disposed opposite each exhalation port 1131. Therefore, in the inspiration process, each guide part 14 can pertinently prevent the atomized air in the sub-air passage from being discharged from the expiration hole 1131 opposite to the sub-air passage, so that the blocking effect on the atomized air is improved, more atomized air is inhaled by a human body, and the atomization effect is improved.

Referring to fig. 8, 9 and 10, based on the same concept as the above-mentioned nozzle 10, the present application provides an atomizer 100, which includes an atomizer body 20 and the nozzle 10, wherein the nozzle 10 is disposed at the mist outlet 21 of the atomizer body 20.

The atomizer body 20 can atomize the liquid medicine, and the liquid medicine is smoothly atomized into the atomized gas. The suction nozzle 10 can be connected to a breathing mask or other devices so as to smoothly transmit the atomized air formed by the atomizer body 20 to the human body, thereby realizing a complete atomization process.

As shown in fig. 11, in some embodiments, the nebulizer body 20 has a second air passage 22 therein, which communicates with the mist outlet 21, and an air pressure sensor 23 disposed in the second air passage 22. The air pressure sensor 23 is communicated with the mist outlet 21 through the second air passage 22 to detect air pressure change of the mist outlet 21 and start and stop the atomization process.

It should be noted that, when the suction nozzle 10 is disposed at the mist outlet 21 of the atomizer body 20, the second air passage 22 is communicated with the first air passage 111 and jointly forms a starting air passage of the atomizer 100, so that the air pressure sensor 23 can smoothly detect the air pressure change of the mist outlet 21 and smoothly start and stop the atomization process.

In addition, since the air pressure sensor 23 is communicated with the mist outlet 21 through the second air passage 22, when the human body performs a suction action through the suction nozzle, the air pressure of the mist outlet 21 communicated with the suction nozzle will be changed. Thus, the air pressure sensor 23 can detect the air pressure change of the mist outlet 21, and the atomization process can be started or stopped according to the air pressure detection result.

Specifically, as shown in fig. 11, when a human body inhales, the air pressure sensor 23 in the second air passage 22 detects a change in air pressure in the second air passage 22, so that the nebulizer 100 is started to start the nebulizing process. As shown in fig. 12, when the human body exhales, the exhaled gas is exhausted from the first airway 111 through the exhalation port 1131, so that the detection effect of the air pressure sensor 23 in the second airway 22 is not affected.

Further, the suction nozzle 10 and the mist outlet 21 of the atomizer body 20 can be screwed together, that is, an external thread is provided at the mist outlet 21 of the atomizer body 20, and a corresponding internal thread is provided at the air inlet 1111 of the suction nozzle 10, thereby realizing the screw connection between the two. The threaded connection enables the connection between the suction nozzle 10 and the atomizer body 20 to be more flexible, and facilitates disassembly and assembly.

In some embodiments, the atomizer 100 includes a second baffle (not shown). The second liquid blocking portion is disposed on an inner wall of the second air duct 22, and is located between the mist outlet 21 and the air pressure sensor 23, so as to block liquid on the inner wall of the second air duct 22 from flowing into the air pressure sensor 23.

It should be noted that the structure of the second liquid blocking portion may be the same as that of the first liquid blocking portion, that is, the second liquid blocking portion is set to be a liquid blocking structure protruding out of the inner wall of the second air duct 22, so that the second liquid blocking portion can block the liquid flow path deposited on the inner wall of the second air duct 22, and liquid is prevented from flowing into the air pressure sensor 23 along the inner wall of the second air duct 22.

It is understood that the structure of the second liquid blocking portion may be different from that of the first liquid blocking portion, for example, the second liquid blocking portion is configured as a groove structure on the inner wall of the second air duct 22, the groove structure can also block the flow path of the liquid deposited on the inner wall of the second air duct 22, and temporarily store the liquid in the groove structure, so as to prevent the liquid from flowing into the air pressure sensor 23 along the inner wall of the second air duct 22.

Specifically, in the present embodiment, the second liquid blocking portion has the same structure as the first liquid blocking portion. Therefore, the second liquid blocking part can block part of liquid entering the second air passage 22, and the liquid is prevented from flowing into the air pressure sensor 23 along the inner wall of the second air passage 22, so that the normal work of the air pressure sensor 23 is ensured, and the normal starting of the atomizer is ensured.

Further, the atomizer 100 includes an atomizing plate assembly 30, and the atomizing plate assembly 30 is disposed between the atomizer body 20 and the suction nozzle 10. The atomizing plate assembly 30 can atomize the liquid medicine in the atomizer main body 20, so that the liquid medicine is smoothly converted into the atomizing air which can be inhaled by a human body, thereby realizing the atomizing process.

Specifically, the atomizing plate assembly 30 is disposed between the mist outlet 21 of the atomizer main body 20 and the air inlet 1111 of the suction nozzle 10, so that the atomized atomizing air can enter the first air channel 111 more completely and be inhaled by the human body.

Referring again to fig. 1, based on the same concept as the atomizer 100, the present application provides an electronic atomizer 1000, which includes a power supply assembly (not shown) and the atomizer 100 as described above, wherein the power supply assembly is electrically connected to the atomizer 100. The power supply assembly can supply power to the nebulizer 100 so that the nebulizer 100 can heat and atomize the liquid medicine stored therein after being energized.

The power supply unit may be provided inside the atomizer 100 or may be provided as an external power supply. In the embodiment, the power supply assembly is disposed inside the atomizer 100, so that the electronic atomizer 1000 can be used more conveniently.

When this application is used specifically, when the human body breathes in, baroceptor 23 detects the atmospheric pressure change in second air flue 22 to make atomizer 100 open and work, heat the atomizing to the liquid medicine of saving in atomizer 100, so that be inhaled by the human body.

When a person exhales, the exhaled gas in the first airway 111 can be directly exhausted from the first airway 111 to the outside through the exhalation port 1131, and therefore, the exhaled gas does not enter the second airway 22, and the normal operation of the nebulizer 100 can be ensured.

In addition, when the liquid is deposited on the inner wall of the first air duct 111 and flows to the air inlet 1111 of the first air duct 111 along the inner wall of the first air duct 111, the first liquid blocking portion 12 on the inner wall of the first air duct 111 can block the liquid, so as to prevent the liquid from flowing into the air inlet 1111 of the first air duct 111, and further prevent the liquid from entering the second air duct 22. Therefore, the stability of judging the air pressure value is increased, and the normal starting of the atomizer 100 is ensured.

If a part of the liquid still enters the second air passage 22, the part of the liquid can be blocked by the second liquid blocking portion on the inner wall of the second air passage 22, so as to further prevent the liquid from flowing into the air pressure sensor 23, thereby further ensuring the normal starting of the atomizer 100.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
