It should be noted that the features of the embodiments of the present invention may be combined with each other without conflict.
The following detailed description of embodiments of the invention refers to the accompanying drawings.
Referring to fig. 1, the present embodiment provides a nasal aspirator 100, which has a simple structure and is easy to disassemble, wash and assemble; meanwhile, liquid can be effectively prevented or reduced from entering the device, the failure rate of the device is reduced, the service life of the device is prolonged, and therefore better use experience is provided for users.
In an embodiment of the present invention, the nasal aspirator 100 comprises a housing assembly 110, a sealing membrane 120 and a power assembly 130, wherein the sealing membrane 120 is disposed in the housing assembly 110 and forms a first chamber 111 and a second chamber 112 with the housing assembly 110, the first chamber 111 and the second chamber 112 are isolated from each other, the housing assembly 110 opens a suction opening 113 in the first chamber 111, the suction opening 113 is communicated with the first chamber 111, and the power assembly 130 is connected with the second chamber 112 and is used for changing the volume of the first chamber 111 and the second chamber 112 so as to generate a suction force near the suction opening 113.
It should be noted that in the embodiment of the present invention, the casing assembly 110 is a casing part of the nasal aspirator 100, and the sealing membrane 120 mainly functions to separate the interior of the casing assembly 110 into the first chamber 111 and the second chamber 112 which are isolated from each other, that is, at the sealing membrane 120, the first chamber 111 and the second chamber 112 are sealed and do not "leak" through the sealing membrane 120. The primary function of the power assembly 130 is to cause the sealing diaphragm 120 to vary the volume of the first and second chambers, such as by creating a negative pressure. In the embodiment of the present invention, the first chamber 111 is provided with a nasal suction opening 113, and when in use, the nasal suction opening 113 is close to the nasal cavity and generates negative pressure to suck the substances in the nasal cavity out of the nasal cavity or into the nasal suction opening 113 and the first chamber 111. Because the sealing membrane 120 is disposed between the first chamber 111 and the second chamber 112, the substance sucked out from the nasal cavity cannot flow into the second chamber 112 through the suction opening 113 and the first chamber 111 (in a specific embodiment, the second chamber 112 is usually located inside the device), so that the liquid entering the device is reduced or prevented, which is beneficial to reducing or preventing the liquid from corroding the devices in the device, and the service life of the device is prolonged.
It should be noted that, in the embodiment of the present invention, the sealing membrane 120 separates the interior of the housing assembly 110 into the first chamber 111 and the second chamber 112, and the first chamber 111 and the second chamber 112 are isolated from each other, that is, the first chamber 111 and the second chamber 112 are not communicated, the first chamber 111 is provided with the nostril 113, and when in use, a port of the nostril 113 is placed in or near the nasal cavity of the user, and a suction force is generated near the nostril 113, so as to achieve a nasal suction effect. In the embodiment of the present invention, the first chamber 111 and the second chamber 112 are isolated from each other, and substances such as nasal mucus sucked through the suction opening 113 are sucked into the first chamber 111 along the suction opening 113, but not into the second chamber 112, thereby effectively preventing the liquid from further entering the inside of the device. Under the action of the power assembly 130, the second chamber 112 generates negative pressure, and under the action of the sealing diaphragm 120, the volumes of the first chamber 111 and the second chamber 112 are changed, so that the volume of the first chamber 111 is increased, and the volume of the second chamber 112 is decreased; the increased volume of the first chamber 111 may create a negative pressure at the inhalation port 113, which may provide an inhalation effect.
Meanwhile, it should be noted that, in the embodiment of the present invention, when the power assembly 130 is a negative pressure device, it may be used to generate a negative pressure, so that the volumes of the first chamber 111 and the second chamber 112 are changed, thereby generating a negative pressure at the nasal suction opening 113 of the first chamber 111, and playing a nasal suction effect. The change in volume of the first and second chambers 111, 112 may be accomplished in a variety of ways, including but not limited to by deformation or change in position of the sealing diaphragm 120, etc. Of course, without limitation, the power assembly 130 may also be in other forms of power, such as a cylinder or a hydraulic cylinder, and cooperate with a connecting rod or the like to push the sealing diaphragm to achieve the volume change of the first chamber and the second chamber.
Optionally, in the present embodiment, the sealing membrane 120 includes a silicone membrane or a rubber membrane. That is, the sealing diaphragm 120 has contractibility, and changes the volumes of the first and second chambers 111 and 112 by deformation, thereby generating negative pressure. It should be noted that the manner in which the sealing diaphragm 120 is assembled is not specifically required or limited by the embodiments of the present invention.
In an alternative embodiment, the power assembly 130 may include a negative pressure pump 131, a gas-collecting negative pressure cavity 132, a first gas valve 133 and a second gas valve 134, the negative pressure pump 131 is connected to the gas-collecting negative pressure cavity 132, the gas-collecting negative pressure cavity 132 is communicated with the second cavity 112 through a pipeline, both ends of the first gas valve 133 are communicated with the pipeline to enable the gas-collecting negative pressure cavity 132 to be communicated with or isolated from the second cavity 112, and one end of the second gas valve 134 is communicated with the pipeline.
It should be noted that, in the embodiment of the present invention, when the nasal aspirator 100 is in use, the first air valve 133 and the second air valve 134 are closed, and the negative pressure pump 131 operates to suck the air in the air collecting negative pressure cavity 132, so as to generate a negative pressure in the air collecting negative pressure cavity 132. The first air valve 133 is opened to communicate the air-collecting negative pressure cavity 132 with the second cavity 112, and under the negative pressure action of the air-collecting negative pressure cavity 132, the second cavity 112 is rapidly contracted, the volume is reduced, the volume of the first cavity 111 is rapidly increased therewith, the instantaneous flow of the nasal inhalation hole 113 is increased, the instantaneous suction force is large, and the nasal inhalation effect is good. After a nasal inhalation action, the second air valve 134 is opened, and the first air valve 133 is closed; the second air valve 134 is opened to enable the second chamber 112 to be communicated with the outside, the negative pressure in the second chamber 112 is released, the volume of the second chamber 112 is increased to the initial volume, the volume of the first chamber 111 is reduced to the initial volume, and then the second air valve 134 is closed; the first air valve 133 and the second air valve 134 are closed, the negative pressure pump 131 is started to work, and the next nasal inhalation work is started.
Meanwhile, it should be noted that, in operation, the first air valve 133 is closed, the air in the air collection negative pressure cavity 132 is evacuated by the negative pressure air pump, and then the first air valve 133 is opened, so that the air in the second chamber 112 rapidly enters the intermediate air collection negative pressure cavity 132, and a large flow rate is generated, thereby generating a large suction force in the suction orifice 113. In the embodiment of the present invention, the power of the negative pressure pump 131 is not required, and the negative pressure pump 131 only evacuates the gas in the gas-collecting negative pressure cavity 132, rather than directly generating the negative pressure at the suction opening 113, which does not substantially require the power of the negative pressure pump 131. That is, the volume of the negative pressure pump 131 can be designed to be small. ( Generally, the larger the volume of the negative pressure pump 131, the stronger the suction force; however, in the embodiment of the present invention, the negative pressure is not directly generated at the inhalation hole 113, but the instant high flow rate of gas is generated through the gas-collecting negative pressure chamber and the first gas valve 133, so that the instant large suction force is generated at the inhalation hole 113. )
Alternatively, the negative pressure pump 131 is a micro air pump.
Optionally, in this embodiment, the second air valve 134 is located between the first air valve 133 and the second chamber 112.

Optionally, the second gas valve 134 is a slow release gas valve.
It should be noted that, in the embodiment of the present invention, the power assembly 130 is not limited to the power form of the negative pressure pump, and may also include other power forms, including a hydraulic cylinder, a pneumatic cylinder, a motor, etc. When the power assembly adopts the power form of a negative pressure pump, the sealing diaphragm has deformation characteristics, namely, the volumes of the first chamber and the second chamber can be changed by changing the shape of the sealing diaphragm, and when the power assembly adopts other power forms, the sealing diaphragm can also realize the change of the volumes of the first chamber and the second chamber through the change of positions, for example, the sealing diaphragm is designed into the structural form of a sealing piston and the like.
Referring to fig. 3, in an alternative embodiment, the power assembly 130 includes a driving motor 135, a transmission gear 136 and a link mechanism 137, the driving motor 135 is in transmission connection with the transmission gear 136, one end of the link mechanism 137 is eccentrically connected with the transmission gear 136, and the other end of the link mechanism 137 is connected with the sealing diaphragm 120, the driving motor 135 is configured to drive the transmission gear 136 to rotate, and acts on the link mechanism 137 through the transmission gear 136, so that the link mechanism 137 drives the sealing diaphragm 120 to deform, and changes the volumes of the first chamber 111 and the second chamber 112.
Further, the sealing diaphragm 120 is of a telescopic structure, and the linkage 137 can push the sealing diaphragm 120 to extend or contract, so as to change the volume of the first chamber 111 and the second chamber 112. Fig. 3 shows the sealing diaphragm 129 in a telescopic configuration projecting into the first chamber 111, although other configurations are possible.
It should be noted that in the embodiment shown in fig. 3, the power assembly 130 may be installed in the second chamber 112, and the sealing diaphragm 120 is directly deformed by the link mechanism 137, so that the volume of the first chamber 111 is changed, thereby achieving a large instantaneous flow rate and providing sufficient suction force.
Referring to fig. 2, in the present embodiment, the housing assembly 110 further includes a main housing 114, a separating housing 115 and a suction nozzle housing 116, the main housing 114 is connected to the separating housing 115, the power assembly 130 is installed in an installation cavity defined by the main housing 114 and the separating housing 115, the suction nozzle housing 116 is connected to the separating housing 115 or the main housing 114, and the sealing diaphragm 120 is installed in a cavity defined by the separating housing 115 and the suction nozzle housing 116 and divides the cavity into a first cavity 111 and a second cavity 112.
Alternatively, the nozzle housing 116 is detachably connected to the partition housing 115 or the main body housing 114, and the sealing diaphragm 120 is detachably connected to the nozzle housing 116 or the partition housing 115.
Optionally, the sealing diaphragm 120 is sleeved on the end of the nozzle housing 116, and encloses a first chamber 111 with the nozzle housing 116; alternatively, the sealing diaphragm 120 is disposed on the separating housing 115 and surrounds the second chamber 112 with the separating housing 115.
The nasal aspirator 100 provided in the present embodiment: the sealing diaphragm 120 divides the interior of the housing assembly 110 into a first chamber 111 and a second chamber 112, and the first chamber 111 and the second chamber 112 are isolated from each other, that is, the first chamber 111 and the second chamber 112 are not communicated with each other, the first chamber 111 is provided with the nostril 113, when in use, a port of the nostril 113 is placed in the nasal cavity or near the nostril of a user, and suction is generated near the nostril 113, so that the nasal inhalation effect is realized. In the embodiment of the present invention, the first chamber 111 and the second chamber 112 are isolated from each other, and substances such as nasal mucus sucked through the suction opening 113 are sucked into the first chamber 111 along the suction opening 113, but not into the second chamber 112, thereby effectively preventing the liquid from further entering the inside of the device.
