Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of maternal and infant nursing, and particularly relates to a nose suction device. BACKGROUND

[0002] Infants are prone to catch cold due to their weak constitution, and are accompanied by symptoms of runny nose. During the period when they have not learned to blow their own noses, they often need help from their parents to clean their noses, otherwise, the dried snot will form nasal crusts to block the nasal cavity, thereby affecting the child's breathing.

[0003] As an auxiliary tool, the nose suction device can suck out the snot in the nasal cavity of an infant. Currently, most commonly used nose suction devices are provided with an electric suction pump, which sucks out the snot in the nasal cavity of an infant into a suction chamber. However, during the use of the nose suction device, when there is too much snot in the suction chamber, the snot is easy to be sucked into the electric suction pump, causing the airway of the electric suction pump to be blocked and bacteria to breed, which affects the long-term use of the nose suction device. However, most of the nose suction devices on the market do not have a self-cleaning function. In addition, due to the limitation of the structure of the body, most of the existing nose suction devices have poor waterproof effect or even cannot be waterproofed. When the nose suction device is used, in some application scenarios, snot or water may enter the body and come into contact with the internal electronic components, which is difficult to clean, causing the nose suction device to be easily damaged and further limiting the long-term use of the nose suction device. SUMMARY

[0004] Therefore, the utility model aims to provide a nose suction device which can realize self-cleaning of the electric suction pump and waterproof of the body, thereby prolonging the service life of the nose suction device.

[0005] A nose suction device comprises a body and a suction head, wherein the body is detachably connected with the suction head. The body comprises a shell, an upper cover, a lower cover and a suction pump. The shell is integrally formed in a cylindrical hollow structure. The upper bottom surface of the shell is sealingly fixed with the upper cover, and the lower bottom surface of the shell is sealingly fixed with the lower cover. The shell, the upper cover and the lower cover enclose a closed cavity. The suction pump is located in the closed cavity. The suction pump is a water-air dual-purpose pump.

[0006] The nose suction device has the following advantages. On the one hand, the shell of the body is integrally formed, so that waterproof treatment only needs to be performed on the connection between the upper cover and the lower cover, thereby realizing waterproof of the body, greatly reducing the waterproof treatment area and lowering the production cost. On the other hand, the suction pump is a water-air dual-purpose pump. When snot enters the suction pump, the body can be directly placed in clean water, the suction pump sucks clean water, and the snot is washed away by the flowing clean water in the suction pump, thereby realizing the self-cleaning function.

[0007] As a preferred solution, the upper cover and the lower cover are arranged in parallel, the upper cover is provided with a first air inlet and a first air outlet, the first air inlet is communicated with the air suction end of the air suction pump, and the first air outlet is communicated with the air exhaust end of the air suction pump. Since the fuselage forms a cylindrical hollow structure with the upper cover parallel to the lower cover (the conventional arrangement of the prior art nose aspirator is that the upper cover is inclined relative to the lower cover), the shell is easy to be integrally formed during production, and the assembly of the fuselage can be realized through stamping of both ends, thereby simplifying the production and realizing the sealing and waterproof of the entire fuselage. In addition, the first air inlet and the first air outlet are arranged on the upper cover, the structure is simple, and the production is facilitated. When self-cleaning is required, the clean water entering the air suction pump and the clean water pumped out of the air suction pump are shunted, thereby facilitating cleaning.

[0008] As a preferred solution, the fuselage further comprises a transition end cover, the transition end cover is detachably connected with the upper cover, the transition end cover is detachably connected with the air suction head to form an air suction chamber, the transition end cover is provided with a second air inlet and a second air outlet, the second air inlet is located in the air suction chamber and communicated with the first air inlet, and the second air outlet is located on the side surface of the transition end cover and communicated with the first air outlet. The air inlet and the air outlet are arranged in the air suction chamber and on the side surface of the transition end cover respectively, so that the air suction chamber storing the nasal mucus is separated from the air exhaust channel, thereby facilitating air suction, air exhaust and storage of nasal mucus. When it is required to clean the nasal mucus mistakenly entering the air suction pump through the second air inlet, the transition end cover and the air suction head are only needed to be disassembled, clean water is only needed to be used to enter the air suction pump from the first air inlet and to be exhausted from the first air outlet, and self-cleaning can be realized.

[0009] As a preferred solution, the air suction head comprises a flow guide support arranged in the air suction chamber, one end of the flow guide support is communicated with the second air inlet, the other end of the flow guide support is closed, the side surface of the flow guide support is provided with a third air inlet, the flow guide support forms a flow blocking cavity and a flow guide groove which are separated from each other, and the third air inlet is located in the flow blocking cavity. When the nasal mucus enters the air suction chamber, the nasal mucus is isolated by the flow blocking cavity of the flow guide support and flows down along the flow guide groove, thereby avoiding entering the third air inlet, reducing the frequency of nasal mucus blocking the air suction pump, and further reducing the cleaning frequency.

[0010] As a preferred solution, the suction head further comprises a suction chamber cover and a suction nozzle connected to the suction chamber cover, the suction chamber cover is detachably connected with the transition end cover to form the suction chamber, the axes of the suction chamber cover, the flow guide support and the body are parallel or coincident, and the suction nozzle is obliquely arranged relative to the suction chamber cover. On the one hand, compared with the prior art in which the suction chamber cover is obliquely arranged relative to the body, even if the sizes of the suction chamber cover and the flow guide support are the same, the effective space of the suction chamber for accommodating nasal mucus is increased when the body of the nasal aspirator is vertically used, the possibility of nasal mucus entering the suction pump through the third air inlet due to excessive nasal mucus is reduced, and the nasal mucus is prevented from blocking the suction pump; on the other hand, the oblique arrangement of the suction nozzle relative to the suction chamber cover facilitates the user to insert the suction nozzle into the nasal cavity, and the suction chamber cover and the body can be stably kept in a vertical state when vertically used, so that the effective space of the suction chamber for accommodating nasal mucus is stable.

[0025] In order to make the above-mentioned purposes, features and advantages of the present application more apparent and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0026] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can be practiced in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the present application, therefore the present application is not limited by the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0029] like Figures 1-8 As shown, the nasal aspirator of this utility model includes a body 1 and an air intake head 2, which are detachably connected. The body 1 includes a housing 11, an upper cover 12, a lower cover 13, an air pump 14, a battery 15, a speaker 16, an ambient light 17, a transparent end cap 18, and a control panel. The housing 11 is a cylindrical hollow structure, and the upper bottom surface of the housing 11 is sealed and fixed to the upper cover 12, and the lower bottom surface of the housing 11 is sealed and fixed to the lower cover 13. The upper cover 12 and the lower cover 13 are parallel, and the housing 11, the upper cover 12, and the lower cover 13 enclose a sealed cavity. A sealing ring 3 is provided at the connection between the housing 11 and the upper cover 12 and the lower cover 13. The air pump 14 is located on the side near the upper cover 12, and the battery 15 is located on the side near the lower cover 13. The control panel runs through the sealed cavity of the entire body 1 from top to bottom, and its two ends are fixedly connected to the upper cover 12 and the lower cover 13 by screws, and a rubber gasket 4 is provided at the connection to prevent the body 1 from leaking water.

One end of the transparent end cover 18 is detachably connected with the upper cover 12, and the other end of the transparent end cover 18 is detachably connected with the air suction head 2. The air suction head 2 comprises a suction nozzle 21 and a suction chamber cover 23. The suction chamber cover 23 is detachably connected with the transparent end cover 18 to form a suction chamber 7. The transparent end cover 18 is provided with a second air inlet 181 and a second air outlet 182. The second air inlet 181 is located in the suction chamber 7 and communicated with the first air inlet 121. The second air outlet 182 is located on the side of the transparent end cover 18 and communicated with the first air outlet 122. On one hand, the transparent end cover 18 separates the air suction head 2 from the upper cover 12. When there is nasal mucus in the air suction head, the nasal mucus will contact the transparent end cover 18. At this time, only the transparent end cover 18 needs to be disassembled for direct cleaning. On the other hand, the transparent end cover 18 can make the light emitted by the atmosphere lamp 17 on the surface of the upper cover 12 pass through. In addition, the second air inlet 181 and the second air outlet 182 are arranged in the suction chamber 7 and on the side of the transparent end cover 18 respectively, so that the suction chamber storing the nasal mucus is separated from the gas discharge channel, which is convenient for air suction, air exhaust and nasal mucus storage. When it is necessary to clean the nasal mucus mistakenly entering the air suction pump 14 through the second air inlet 181, only the transparent end cover 18 and the air suction head 2 need to be disassembled. Then, clean water is used to enter the air suction pump from the first air inlet 121 and is discharged from the first air outlet 122 to realize self-cleaning.

[0031] As Figures 5-6As shown, the suction head 2 further comprises a flow guide support 22 located in the suction chamber 7, one end of which is in communication with the second air inlet 181 and the other end is closed, and the side of the flow guide support 22 is provided with a third air inlet 221. The flow guide support 22 forms a flow blocking cavity 222 and a flow guide groove 223 which are separated from each other, and the third air inlet 221 is located in the flow blocking cavity 222. Specifically, the flow guide support 22 comprises a support body 224 and two arc-shaped flow blocking plates 225, which are respectively vertically arranged on the side walls of the support body 224 and open outward to form the flow blocking cavity 222, and the flow guide groove 223 is formed between the support body 224 and the two arc-shaped flow blocking plates 225. Each arc-shaped flow blocking plate 225 comprises a first flow blocking plate 2251, a second flow blocking plate 2252 and a third flow blocking plate 2253; the first flow blocking plate 2251 is arranged on the side wall of the support body 224, and the third air inlet 221 is formed at the corresponding position of the support body 224 and the first flow blocking plate 2251; the two sides of the first flow blocking plate 2251 respectively extend outward to form the second flow blocking plate 2252 and the third flow blocking plate 2253. Preferably, the size of the second flow blocking plate 2252 is larger than that of the third flow blocking plate 2253, and the side of the second flow blocking plate 2252 away from the support body 224 extends downward to the side close to the support body 224, and the side of the third flow blocking plate 2253 close to the support body 224 extends downward to the side away from the support body 224. When the nasal mucus enters the suction chamber 7, it will be isolated by the arc-shaped flow blocking plate 225 of the flow guide support 22 and guided to flow downward through the flow guide groove 223, so that the flow guide support 22 can block and guide the nasal mucus, prevent the nasal mucus from being sucked into the third air inlet 221, reduce the number of times of nasal mucus blocking the suction pump 14, and further reduce the cleaning frequency. In addition, the second flow blocking plate 2252 is arranged in a shape and size such that the nasal mucus can easily flow to the flow guide groove 223 even if it falls on the second flow blocking plate 2252, avoiding entering the flow blocking cavity 222; the third flow blocking plate 2253 is arranged in a shape such that the nasal mucus can easily flow downward into the suction chamber even if it falls on the third flow blocking plate 2253.

[0032] Preferably, the axes of the machine body 1, the flow guide support 22 and the suction chamber cover 23 are parallel or coincident, and the suction nozzle 21 is arranged obliquely relative to the axis of the machine body 1 and extends along the first direction 61.
