Description

Technical Field

[0001] The present application relates to the field of cleaning technology, and more specifically, to a nasal suction head assembly and a nasal care device. Background Art

[0002] Nasal care equipment, such as a nasal aspirator, is a tool that can be used to suck out dirt from the nasal cavity. Usually, the fluid in the nostrils can be sucked into a liquid storage tank that stores dirty fluid through a suction device, thereby discharging pathogens and dirt that have accumulated in the nasal cavity, restoring the nasal cavity to a normal physiological environment, restoring the nasal cavity's self-detoxification function, and achieving the purpose of protecting the nasal cavity. The current nasal care equipment requires many structures to form a negative pressure cavity that can suck out fluid, and the structure is complex. In addition, the multiple components of the nasal care equipment are difficult to disassemble from each other, and the cleaning process is relatively cumbersome. Utility Model Content

[0003] The embodiments of the present application provide a nasal suction head assembly and a nasal care device, which are at least used to solve the problem of complex structure of the nasal care device.

[0004] The nose suction head assembly of the embodiment of the present application includes a liquid storage tank and a nose suction head. The liquid storage tank is formed with a liquid storage cavity and an air suction port that are interconnected. The liquid storage cavity is used to store fluid. The air suction port is provided on the bottom wall of the liquid storage tank and is connected to a suction device provided outside the liquid storage tank so that a vacuum is formed in the liquid storage cavity. The nose suction head is a one-piece component. The nose suction head is detachably mounted on the top wall of the liquid storage tank to seal the opening of the liquid storage cavity. The nose suction head is used to contact the nasal cavity to suck the fluid. The inner cavity of the nose suction head is also used to communicate with the liquid storage cavity to allow the fluid to flow into the liquid storage cavity.

[0005] The nose suction head can be detachably mounted on the liquid storage tank and can seal the opening of the liquid storage tank. During the use of the nose suction head assembly, the suction device can suck the gas in the liquid storage cavity to reduce the air pressure in the liquid storage cavity. At this time, the liquid in the nasal cavity can enter the liquid storage cavity under the action of the air pressure difference and be stored. When cleaning the nose suction head assembly, the nose suction head only needs to be removed from the liquid storage tank for cleaning. The nasal care device has a simple structure and is easy to clean.

[0006] In some embodiments, the nasal suction head includes a support frame and a flexible portion. The support frame is mounted on the top wall of the liquid storage tank to cover the opening of the liquid storage cavity. The flexible portion is arranged on the side of the support frame away from the liquid storage cavity, and the hardness of the support frame is greater than the hardness of the flexible portion, so as to support the flexible portion. The nasal suction head is provided with a liquid suction port that passes through the flexible portion and the support frame, and the liquid suction port is connected to the liquid storage cavity. The flexible portion is used to contact the nasal cavity so that the fluid in the nasal cavity enters the liquid storage cavity through the liquid suction port.

[0007] When the suction device sucks the gas in the liquid storage cavity through the suction tube, the flexible part can contact the inner side of the nasal cavity, and the liquid and gas in the nasal cavity will be sucked into the liquid storage cavity through the suction nozzle. Among them, the support frame is a hard structure, and the flexible part is a flexible structure. The support frame can support the flexible part to prevent the flexible part from being excessively deformed and blocking the suction nozzle due to changes in air pressure during the suction process of the suction device.

[0008] In some embodiments, the flexible portion includes a first portion and a second portion connected to each other, and the second portion is connected to the outer wall of the support frame. The first portion is used to contact the nasal cavity, and the liquid suction port passes through the first portion and the support frame. The second portion is at least partially sandwiched between the support frame and the liquid storage tank, and is used to seal the gap between the support frame and the liquid storage tank.

[0009] The first part of the flexible portion is a flexible portion that can extend into the nasal cavity and contact the nasal cavity. When the first part is subjected to force, the outer wall of the first part will partially deform to cooperate with the nasal cavity to increase the comfort of the user during use. The second part of the flexible portion can be connected to the outer wall of the support frame to prevent the flexible portion from falling off the support frame during use, and the connection between the flexible portion and the support frame is more stable. At the same time, the second part of the flexible portion is at least partially sandwiched between the support frame and the liquid storage tank, which can play a role in sealing the gap between the support frame and the liquid storage tank, avoiding the use of a sealing ring, further simplifying the structure of the nasal suction head assembly, and making the nasal suction head assembly easier to disassemble and clean.

[0010] In some embodiments, the first portion and the second portion are connected, and the flexible portion is an integrated soft rubber part formed on the support frame.

[0011] The flexible part is an integrated soft rubber part. On the one hand, compared with first forming the first part, then forming the second part, and then assembling the two together to form the flexible part, the integrated soft rubber part is usually made by an integrated molding process, and the process is simpler; on the other hand, the structure of the integrated soft rubber part is more stable, the risk of subsequent deformation or breakage is lower, and the service life is longer.

[0012] In certain embodiments, the thickness of the first portion is greater than the thickness of the second portion.

[0013] When the thickness of the first part is greater than that of the second part, the first part can maintain a relatively stable shape when it is made of a flexible material. During use, the first part will be subjected to force and partially deformed to fit the interior of the nasal cavity, and the thicker first part can also support the nasal cavity to avoid excessive deformation during suction, causing the liquid suction port to be closed under the action of the air pressure difference to ensure smooth suction of the liquid.

[0014] In some embodiments, the nasal suction head is provided with a liquid suction port, the liquid suction port is connected to the liquid storage cavity, and the liquid suction port is used to allow the fluid in the nasal cavity to enter the liquid storage cavity. The nasal suction head assembly also includes a liquid suction tube, which is connected to the nasal suction head and extends into the liquid storage cavity. The liquid suction tube is connected to both the liquid suction port and the liquid storage cavity and is used to allow the fluid to flow through.

[0015] The suction tube is a tubular structure extending from the suction nose tip at least into the liquid storage cavity. The suction tube is connected to the suction port. When the suction device sucks the gas in the liquid storage cavity, the fluid in the nasal cavity will enter the suction tube through the suction port, and then flow down or directly fall through the suction tube to enter the liquid storage cavity.

[0016] In certain embodiments, an outer wall of the pipette is spaced apart from an inner wall of the liquid storage chamber.

[0017] When the outer wall of the suction tube is spaced from the inner wall of the liquid storage cavity, when the nose suction head assembly is tilted for use, the liquid will flow between the outer wall of the suction tube and the inner wall of the liquid storage cavity. During cleaning, only the space between the suction tube and the liquid storage cavity needs to be cleaned, without cleaning multiple cavities, which makes cleaning more convenient.

[0018] In certain embodiments, the central axis of the pipette coincides with the central axis of the liquid storage chamber.

[0019] When the central axis of the pipette coincides with the central axis of the liquid storage chamber, the pipette can be located at the center of the liquid storage chamber relative to the liquid storage chamber. When the liquid in the nasal cavity flows into the liquid storage chamber through the pipette, the liquid entering the liquid storage chamber will first accumulate on the bottom wall of the liquid storage chamber at the center, and then flow to other positions of the liquid storage chamber.

[0020] In some embodiments, the pipette is passed through the suction head, the first end of the pipette passes through the suction port and protrudes out of the suction head, and the second end of the pipette extends into the liquid storage cavity.

[0021] The pipette and the nose suction head are detachable structures. When cleaning the nose suction head assembly, the pipette can be removed from the nose suction head for cleaning alone. When the first end of the pipette passes through the suction port and protrudes out of the nose suction head, the pipette can be more accurately aligned with the inside of the nasal cavity so that all the fluid enters the pipette.

[0022] In some embodiments, in the direction of the central axis of the liquid storage tank, the length of the pipette ranges from [1 cm, 5 cm].

[0023] When the length of the pipette is less than 1 cm, the distance between the outlet of the pipette and the nose suction head is too short. When the liquid in the pipette falls, the liquid will splash onto the inner wall of the nose suction head and the inner wall of the liquid storage chamber, making the nose suction head difficult to clean. When the length of the pipette is greater than 5 cm, the distance between the outlet of the pipette and the bottom wall of the liquid storage chamber is too small, and the suction port is easy to conflict with the bottom wall of the liquid storage chamber, making it difficult for the liquid to flow out. When liquid accumulates in the liquid storage chamber, if the distance between the outlet of the pipette and the bottom wall of the liquid storage chamber is too small, the liquid in the liquid storage chamber will flow back into the pipette.

[0024] In some embodiments, the nasal suction head assembly further includes an air suction pipe arranged around the air suction port, the air suction pipe is arranged in the liquid storage tank and is formed as a component with the liquid storage tank. The first end of the air suction pipe is provided with an air suction hole connected to the liquid storage cavity, and the second end of the air suction pipe is connected to the suction device through the air suction port. Along the direction of the central axis of the liquid storage tank, the distance between the outlet of the liquid suction pipe and the bottom wall of the liquid storage cavity is smaller than the distance between the air suction hole of the air suction pipe and the bottom wall of the liquid storage cavity.

[0025] The suction tube is a through structure connecting the liquid storage chamber and the suction device. When the distance between the outlet of the suction tube and the bottom wall of the liquid storage chamber is smaller than the distance between the suction hole of the suction tube and the bottom wall of the liquid storage chamber, the outlet of the suction tube is closer to the bottom wall of the liquid storage chamber than the position of the suction hole. When the suction device sucks the gas in the liquid storage chamber, the gas will enter the suction tube from the suction hole, and the fluid in the nasal cavity will flow into the suction tube through the suction port and flow out from the outlet of the suction tube. Since the relative position of the outlet of the suction tube is lower, the liquid will directly accumulate on the bottom wall of the liquid storage chamber, and the liquid level will also be lower than the position of the suction hole, so as to prevent the liquid from entering the suction tube under the action of the air pressure difference during the suction process.

[0026] In certain embodiments, in a plane perpendicular to the central axis of the liquid storage tank, a projection of the air suction tube does not overlap with a projection of the liquid suction tube.

[0027] When the projection of the air intake pipe and the projection of the liquid suction pipe do not overlap, the air intake pipe and the liquid suction pipe will be staggered with each other. At this time, the liquid flowing out of the liquid suction pipe will not contact the air intake pipe, thereby preventing the fluid from entering the air intake hole of the air intake pipe, and further preventing the fluid from entering the suction device connected to the air intake port.

[0028] In some embodiments, the diameter of the liquid suction tube is larger than the diameter of the air suction hole.

[0029] The diameter of the suction tube is larger than the diameter of the suction hole, which can facilitate the suction of liquid in the nasal cavity into the liquid storage cavity and reduce the backflow into the suction tube.

[0030] In some embodiments, the diameter of the liquid suction tube is larger than the diameter of the air suction tube.

[0031] The diameter of the suction tube is larger than that of the air intake tube, which can facilitate the suction of liquid in the nasal cavity into the liquid storage cavity and reduce backflow into the air intake tube.

[0032] In some embodiments, the suction tube is integrally formed with the nasal suction head.

[0033] The suction pipe and the nasal suction head are integrally formed, which further simplifies the structure of the nasal suction head assembly and makes the nasal suction head assembly easier to disassemble, assemble and clean.

[0034] The nasal care device of the embodiment of the present application includes the nasal suction head assembly and the suction device described in any of the above embodiments, and the suction device is connected to the suction port, and the suction device is used to extract the fluid in the liquid storage cavity.

[0035] The nasal care device can clean the nasal cavity by sucking the fluid in the nasal cavity through the nasal suction head component.

[0036] In some embodiments, the nasal suction head assembly is detachably connected to the suction device, and the suction device includes an air suction port, and the air suction port of the suction device is sealed and connected to the suction port.

[0037] When the suction port and the exhaust port are sealed and connected, the gas will only flow from the liquid storage chamber into the suction device, and will not enter the suction device from the connection between the nose suction head assembly and the suction device, so that the air pressure in the liquid storage chamber will decrease rapidly, the air pressure difference between the inside and the outside will be larger, and the suction effect will be better.

[0053] See also Figure 1 and Figure 2 The nose suction head assembly 100 of the present application includes a liquid storage tank 10 and a nose suction head 30. The liquid storage tank 10 is formed with a liquid storage cavity 11 and an air inlet 13 that are interconnected. The liquid storage cavity 11 is used to store fluid. The air inlet 13 is arranged on the bottom wall of the liquid storage tank 10 and is connected to a suction device 300 ( Figure 7 The suction nozzle 30 is a one-piece component, which is detachably mounted on the top wall 101 of the liquid storage box 10 to seal the opening of the liquid storage chamber 11. The suction nozzle 30 is used to contact the nasal cavity to suck the fluid. The inner cavity 3103 of the suction nozzle 30 is also used to communicate with the liquid storage chamber 11 to allow the fluid to flow into the liquid storage chamber 11.

[0054] In the nose suction head assembly 100 of the present application, the nose suction head 30 is detachably mounted on the liquid storage tank 10 and is capable of sealing the opening of the liquid storage tank 10. During the use of the nose suction head assembly 100, the suction device 300 ( Figure 7 The nasal cavity care device 1000 can be cleaned by simply removing the nasal suction head 30 from the liquid storage box 10. The nasal cavity care device 1000 has a simple structure and is easy to clean.

[0055] The nose suction head assembly 100 is further described below with reference to the accompanying drawings.

[0056] See also Figure 1 and Figure 2 In some embodiments, the liquid storage tank 10 is a box structure capable of storing liquid. The liquid storage tank 10 is used to store fluid flowing out of the nasal cavity. The cleaning liquid stored in the liquid storage tank 10 can be water or a mixed cleaning liquid with other ingredients added, which is not limited here. The material of the liquid storage tank 10 includes but is not limited to metal, plastic or silicone, etc. Among them, the outer contour of the cross section of the liquid storage tank 10 can be a regular shape (for example: a perfect circle, an ellipse, a polygon, etc.) or an irregular shape.

[0057] Specifically, in some embodiments, the liquid storage tank 10 is provided with a top wall 101 and a bottom wall 103 facing each other, the top wall 101 of the liquid storage tank 10 faces the nose suction head 30, and the bottom wall 103 of the liquid storage tank 10 is used to connect with other structures. The liquid storage tank 10 has a central axis A, which at least passes through at least two of the three-dimensional geometric center of the liquid storage tank 10, the geometric center of the cross section of the top wall 101 of the liquid storage tank 10, or the geometric center of the cross section of the bottom wall 103 of the liquid storage tank 10. And the central axis A of the liquid storage tank 10 is at least perpendicular to the top wall 101 of the liquid storage tank 10 and / or the bottom wall 103 of the liquid storage tank 10. The extension direction of the central axis A of the liquid storage tank 10 is the first direction X, and the extension direction perpendicular to the central axis A of the liquid storage tank 10 is the second direction Y. Among them, the first direction X and the second direction Y are perpendicular to each other.

[0058] More specifically, in some embodiments, the liquid storage chamber 11 of the liquid storage box 10 can be connected to the nasal cavity through the nasal suction head 30, and can also be connected to the suction device 300 ( Figure 7 In the suction device 300 ( Figure 7 When extracting gas, the gas in the liquid storage chamber 11 will enter the suction device 300 ( Figure 7 At this time, the air pressure in the liquid storage chamber 11 decreases, and a pressure difference is generated between the inside and outside of the liquid storage chamber 11. Under the action of the pressure difference, the fluid in the nasal cavity is sucked into the liquid storage chamber 11 from the nose suction head 30. In some embodiments, the air inlet 13 is provided on the bottom wall of the liquid storage tank 10, and the suction device 300 ( Figure 7 The suction device 300 (shown) can be installed on the side where the bottom wall 103 of the liquid storage tank 10 is located and directly corresponds to the air inlet 13. In other embodiments, the air inlet 13 is arranged on the side wall of the liquid storage tank 10, and part of the structure of the nasal care device 1000 can wrap part of the outer wall of the liquid storage tank 10 so that the suction device 300 ( Figure 7 The air inlet 13 may be indirectly corresponding to the air inlet 13. The shape of the air inlet 13 includes but is not limited to a perfect circle, an ellipse or a polygon.

[0059] See also Figure 2 and Figure 3 In some embodiments, the suction head 30 is generally a structure that can contact the nasal cavity and allow the liquid in the nasal cavity to be sucked into the liquid storage chamber 11. Figure 7 (shown in the figure) when the gas in the liquid storage cavity 11 is sucked through the air inlet 13, part of the structure of the nasal suction head 30 can contact the inside of the nasal cavity, and another part of the structure of the nasal suction head 30 can be connected to the liquid storage tank 10 and seal the liquid storage cavity 11 at the top wall 101 of the liquid storage tank 10. Therefore, when the air pressure in the liquid storage cavity 11 decreases, the external fluid can only enter the liquid storage cavity 11 through the part of the nasal suction head 30 that contacts the inside of the nasal cavity.

[0060] Specifically, in some embodiments, Figure 4 As shown, the nose suction head 30 is only composed of the flexible portion 33, part of the structure of the flexible portion 33 is installed on the top wall 101 of the liquid storage tank 10, and another part of the structure of the flexible portion 33 is in contact with the nasal cavity. Figure 3 As shown, the nose suction head 30 includes a support frame 31 and a flexible portion 33. The flexible portion 33 is an integrated soft rubber part formed on the support frame 31. The material of the flexible portion 33 includes but is not limited to plastic, silicone or rubber. The support frame 31 is installed on the top wall 101 of the liquid storage box 10 to cover the opening of the liquid storage cavity 11. The flexible portion 33 is arranged on the side of the support frame 31 away from the liquid storage cavity 11. Figure 7 (shown in the figure) When the gas in the liquid storage cavity 11 is sucked through the suction port 13, the flexible portion 33 can contact the inner side of the nasal cavity. In some embodiments, the liquid and gas in the nasal cavity will enter the liquid storage cavity 11 through the inner cavity of the support frame 31 (i.e., the inner cavity 3103 of the nasal suction head 30). In other embodiments, the liquid and gas in the nasal cavity will enter the liquid storage cavity 11 through the inner cavity between the flexible portion 33 and the support frame 31 (i.e., a part of the inner cavity 3103 of the nasal suction head 30) and the inner cavity of the support frame 31 (i.e., another part of the inner cavity 3103 of the nasal suction head 30). Among them, the support frame 31 is a hard structure, the flexible portion 33 is a flexible structure, and the hardness of the support frame 31 is greater than the hardness of the flexible portion 33. The support frame 31 can support the flexible portion 33 to avoid the suction device 300 ( Figure 7 During the air extraction process (shown in the figure), the flexible portion 33 is excessively deformed due to the change in air pressure, thereby blocking the nose suction tip 30.

[0061] More specifically, in some embodiments, the nose suction head 30 is provided with a liquid suction port 3101 penetrating the flexible portion 33 and the support frame 31, and the liquid suction port 3101 is connected to the liquid storage chamber 11. Figure 7(shown in the figure) when the gas in the liquid storage cavity 11 is sucked through the suction port 13, the flexible portion 33 is used to contact the nasal cavity so that the fluid in the nasal cavity enters the liquid storage cavity 11 through the suction port 3101, the inner cavity between the flexible portion 33 and the support frame 31 (i.e., a part of the inner cavity 3103 of the nasal suction head 30) and / or the inner cavity of the support frame 31 (i.e., another part of the inner cavity 3103 of the nasal suction head 30). In some embodiments, the suction port 3101 is provided on the top surface of the end of the nasal suction head 30 away from the liquid storage tank 10 and is provided on the central axis of the liquid storage tank 10. In other embodiments, the suction port 3101 is provided on the side wall of the nasal suction head 30, and the direction in which the suction port 3101 is oriented intersects with the central axis of the liquid storage tank 10.

[0062] More specifically, please combine Figure 2 In some embodiments, the flexible portion 33 includes a first portion 331 and a second portion 333 connected to each other, and the first portion 331 of the flexible portion 33 is a flexible portion that can extend into the nasal cavity and contact the nasal cavity. The first portion 331 is used to contact the nasal cavity, and the liquid suction port 3101 runs through the first portion 331 and the support frame 31. The second portion 333 is a structure that can be wrapped around the side of the support frame 31 away from the liquid storage chamber 11 and connected to the outer wall of the support frame 31. When the first portion 331 is subjected to force, the outer wall of the first portion 331 will be partially deformed to cooperate with the nasal cavity to increase the comfort of the user during use. The second portion 333 of the flexible portion 33 can be connected to the outer wall of the support frame 31 to prevent the flexible portion 33 from falling off the support frame 31 during use, and the connection between the flexible portion 33 and the support frame 31 is more stable. The second part 333 is at least partially sandwiched between the support frame 31 and the liquid storage tank 10. The second part 333 can be used to seal the gap between the support frame 31 and the liquid storage tank 10, thereby avoiding the use of a sealing ring, further simplifying the structure of the nose suction head assembly 100, and making the nose suction head assembly 100 easier to disassemble and clean. In addition, the flexible part 33 is an integrated soft rubber part. On the one hand, compared with first forming the first part 331, then forming the second part 333, and then assembling the two together to form the flexible part 33, the integrated soft rubber part is usually made by an integrated molding process, and the process is simpler; on the other hand, the structure of the integrated soft rubber part is more stable, the risk of subsequent deformation or breakage is lower, and the service life is longer.

[0063] Specifically, please combine Figure 5In some embodiments, the thickness L1 of the first portion 331 is greater than the thickness L2 of the second portion 333. When the thickness L1 of the first portion 331 is greater than the thickness L2 of the second portion 333, the first portion 331 can maintain a relatively stable shape when it is made of a flexible material. During use, the first portion 331 will be stressed and partially deformed to fit the inside of the nasal cavity, and the first portion 331 with a larger thickness can also support the nasal cavity to avoid excessive deformation during the suction process, resulting in the liquid suction port 3101 being closed under the action of the air pressure difference to ensure smooth suction of the liquid.

[0064] See also Figure 2 and Figure 3 In some embodiments, the suction head assembly 100 further includes a liquid suction tube 35, which is a tubular structure with two ends connected, and the liquid suction tube 35 is used for allowing fluid to flow through. The liquid suction tube 35 is connected to the suction head 30, and is connected to the suction port 3101 and the liquid storage chamber 11. The liquid suction tube 35 includes a first end 351 and a second end 353 opposite to each other. The first end 351 of the liquid suction tube 35 is connected to the suction port 3101 on the suction head 30, and the second end 353 of the liquid suction tube 35 extends from the suction head 30 at least into the liquid storage chamber 11 and is disposed in the liquid storage chamber 11. In the suction device 300 ( Figure 7 (shown in the figure) when the gas in the liquid storage chamber 11 is sucked, the fluid in the nasal cavity will enter the liquid suction tube 35 from the first end 351 of the liquid suction tube 35 through the liquid suction port 3101, and then flow down through the inner wall of the liquid suction tube 35 or fall directly from the second end 353 of the liquid suction tube 35 to enter the liquid storage chamber 11.

[0065] Further, in some embodiments, the pipette 35 is provided through the nasal suction head 30, the first end 351 of the pipette 35 passes through the suction port 3101 and protrudes outside the nasal suction head 30, and the second end 353 of the pipette 35 extends into the liquid storage chamber 11. In some embodiments, the pipette 35 and the nasal suction head 30 are an integral structure. When cleaning the nasal suction head assembly 100, the user can clean the nasal suction head 30 and the pipette 35 together. In other embodiments, the pipette 35 is detachably mounted on the nasal suction head 30. When cleaning the nasal suction head assembly 100, the pipette 35 can be removed from the nasal suction head 30 and cleaned separately. When the first end 351 of the pipette 35 passes through the suction port 3101 and protrudes outside the nasal suction head 30, the pipette 35 can be more accurately aligned with the inside of the nasal cavity so that all the fluid enters the pipette 35. The second end 353 of the pipette 35 is provided with a fluid outlet. In some embodiments, the fluid outlet is provided on the side wall of the pipette 35. In other embodiments, along the first direction X, the fluid outlet is provided on the bottom surface of the pipette 35.

[0066] Furthermore, in some embodiments, the outer wall of the pipette 35 is spaced from the inner wall of the liquid storage chamber 11. When the outer wall of the pipette 35 is spaced from the inner wall of the liquid storage chamber 11, when the nose suction head assembly 100 is tilted for use, the liquid will flow between the outer wall of the pipette 35 and the inner wall of the liquid storage chamber 11, and indirectly increase the storage space of the liquid. During the cleaning process, the user only needs to clean the space between the pipette 35 and the liquid storage chamber 11 in the liquid storage tank 10 without cleaning the inner cavity 3103 of the nose suction head 30 and other cavities, which is more convenient to clean.

[0067] Furthermore, in some embodiments, the central axis of the pipette 35 coincides with the central axis A of the liquid storage tank 10. When the central axis of the pipette 35 coincides with the central axis A of the liquid storage tank 10, the pipette 35 can be located at the center of the liquid storage tank 10 relative to the liquid storage tank 10. When the liquid in the nasal cavity flows into the liquid storage tank 10 through the pipette 35, the liquid entering the liquid storage cavity 11 will first accumulate on the bottom wall of the liquid storage cavity 11 at the center, and then flow to other positions of the liquid storage cavity 11 under the action of gravity. Therefore, when the nose suction head assembly 100 is tilted, the side wall of the liquid storage tank 10 at a higher position and the inner wall of the nose suction head 30 at a higher position will not contact the liquid, making cleaning more convenient.

[0068] Furthermore, please combine Figure 5 In some embodiments, in the direction of the central axis of the liquid storage tank 10, the length H0 of the pipette 35 ranges from [1 cm, 5 cm]. For example, H0 is 1.0 cm, 1.5 cm, 2.0 cm, 2.2 cm, 2.5 cm, 3.0 cm, 3.5 cm, 3.7 cm, 4.0 cm, 4.5 cm or 5.0 cm. When the length H0 of the pipette 35 is less than 1 cm, the distance between the outlet of the second end 353 of the pipette 35 and the suction head 30 is too short. When the liquid in the pipette 35 falls, the liquid will splash onto the inner wall of the suction head 30 and the inner wall of the liquid storage chamber 11, making it difficult to clean the suction head 30. When the length H0 of the pipette 35 is greater than 5 cm, the distance between the outlet of the pipette 35 and the bottom wall of the liquid storage chamber 11 is too small, and the suction port 3101 easily conflicts with the bottom wall of the liquid storage chamber 11, making it difficult for the liquid to flow out. When liquid is accumulated in the liquid storage chamber 11, if the distance between the outlet of the liquid pipette 35 and the bottom wall of the liquid storage chamber 11 is too small, the liquid in the liquid storage chamber 11 will flow back into the liquid pipette 35. Therefore, when the length H0 of the liquid pipette 35 is in the range of [1 cm, 5 cm], there is a gap between the liquid suction port 3101 and the bottom wall of the liquid storage chamber 11 sufficient to store liquid, and the liquid will not splash onto the inner wall of the suction head 30 and the inner wall of the liquid storage chamber 11.

[0069] See also Figure 3 and Figure 4 In some embodiments, the nose suction head assembly 100 may further include an air suction pipe 50. The air suction pipe 50 is generally a tubular structure through which gas can flow. The liquid storage chamber 11 of the liquid storage tank 10 can be connected to the suction device 300 ( Figure 7 In the suction device 300 ( Figure 7 When the gas is extracted, the gas in the liquid storage chamber 11 will enter the suction device 300 ( Figure 7 The inner contour size of the air inlet 13 can at least correspond to the inner contour size of the air inlet 50. The air inlet 50 is arranged in the liquid storage box 10 and surrounds the air inlet 13. The air inlet 50 extends along the first direction X. The opposite ends of the air inlet 50 are respectively connected to the liquid storage cavity 11 and the suction device 300 ( Figure 7 Show).

[0070] Specifically, please combine Figure 5 In some embodiments, the air intake pipe 50 includes a first end 501 and a second end 503 opposite to each other. The first end 501 of the air intake pipe 50 is disposed in the liquid storage tank 10 and is a free end. The second end 503 of the air intake pipe 50 is installed on the bottom wall of the liquid storage tank 10 and is connected to the air intake port 13. The air intake pipe 50 is provided with at least one air intake hole 51. The air intake hole 51 on the air intake pipe 50 can be connected with the air intake port 13 and the liquid storage chamber 11 through the air intake pipe 50. In some embodiments, at least one air intake hole 51 is disposed on the top wall of the first end 501 of the air intake pipe 50. In other embodiments, at least one air intake hole 51 is disposed on the side wall of the first end 501 of the air intake pipe 50. In still other embodiments, at least one air intake hole 51 is disposed on the top wall of the first end 501 of the air intake pipe 50 and the side wall of the first end 501 of the air intake pipe 50. In the suction device 300 ( Figure 7 When the gas in the liquid storage chamber 11 is sucked, the gas in the suction pipe 50 is first sucked into the suction device 300 through the suction port 13 ( Figure 7 (shown), at this time, the air pressure in the suction pipe 50 is reduced, and the gas in the liquid storage chamber 11 will flow into the suction pipe 50 through the suction hole 51, so that the air pressure in the liquid storage chamber 11 is reduced, and the fluid in the nasal cavity can enter the liquid storage chamber 11 through the suction head 30 under the action of the air pressure difference. The suction hole 51 is arranged at the first end 351 of the suction pipe 35 so that the position of the suction hole 51 can be higher than the bottom wall of the liquid storage chamber 11. Therefore, when liquid is stored in the liquid storage chamber 11, even if the liquid surface in the suction head assembly 100 is tilted, the liquid will not enter the suction device 300 through the suction hole 51 ( Figure 7 Display) inside.

[0071] More specifically, in some embodiments, along the direction of the central axis of the liquid storage box 10, the distance H1 between the outlet of the liquid pipette 35 and the bottom wall of the liquid storage chamber 11 is smaller than the distance H2 between the suction hole 51 of the suction pipe 50 and the bottom wall of the liquid storage chamber 11. In the case where the distance H1 between the outlet of the liquid pipette 35 and the bottom wall of the liquid storage chamber 11 is smaller than the distance H2 between the suction hole 51 of the suction pipe 50 and the bottom wall of the liquid storage chamber 11, the outlet of the liquid pipette 35 is closer to the bottom wall of the liquid storage chamber 11 than the position of the suction hole 51, and in the suction device 300 ( Figure 7 When the gas in the liquid storage chamber 11 is sucked, the gas will enter the suction tube 50 from the suction hole 51, and the fluid in the nasal cavity will flow into the suction tube 35 through the suction port 3101 and flow out from the outlet of the suction tube 35. Since the outlet of the suction tube 35 is at a lower relative position, the liquid will directly accumulate on the bottom wall of the liquid storage chamber 11, and the liquid level will also be lower than the position of the suction hole 51, so as to prevent the liquid from entering the suction tube 50 under the action of the air pressure difference during the suction process.

[0072] Further, in some embodiments, in a plane perpendicular to the central axis A of the liquid storage tank 10, the projection of the air intake pipe 50 does not overlap with the projection of the liquid suction pipe 35. In the case where the projection of the air intake pipe 50 does not overlap with the projection of the liquid suction pipe 35, the air intake pipe 50 and the liquid suction pipe 35 will be staggered from each other, and the liquid flowing out of the liquid suction pipe 35 will not contact the air intake pipe 50, thereby preventing the fluid from entering the air intake hole 51 of the air intake pipe 50, and further preventing the fluid from entering the suction device 300 connected to the air intake port 13.

[0073] Furthermore, in some embodiments, the diameter of the suction tube 35 is larger than the diameter of the suction hole 51. The diameter of the suction tube 35 is larger than the diameter of the suction hole 51, which can facilitate the suction of liquid in the nasal cavity into the liquid storage cavity 11 and reduce the backflow into the suction tube 50.

[0074] Furthermore, in some embodiments, the diameter of the liquid suction tube 35 is larger than the diameter of the air suction tube 50. The diameter of the liquid suction tube 35 is larger than the diameter of the air suction tube 50, which can facilitate the liquid in the nasal cavity to be sucked into the liquid storage cavity 11 and reduce the backflow into the air suction tube 50.

[0075] Furthermore, in some embodiments, the air suction pipe 50 is integrally formed with the nasal suction head. The air suction pipe 50 is integrally formed with the nasal suction head, which further simplifies the structure of the nasal suction head assembly 100 and makes the nasal suction head assembly 100 easier to disassemble and clean.

[0076] See also Figure 6 and Figure 7The nasal care device 1000 of the embodiment of the present application includes the nasal suction head assembly 100 and the suction device 300 of any of the above-mentioned embodiments. The suction device 300 is connected to the air inlet 13, and the suction device 300 is used to extract the fluid in the liquid storage chamber 11.

[0077] In the nasal care device 1000 of the present application, the nasal care device 1000 can clean the nasal cavity by sucking the fluid in the nasal cavity through the nose suction head assembly 100. The suction tube 50 is a structure arranged in the liquid storage tank 10, and the nose suction head 30 is detachably mounted on the liquid storage tank 10. During the use of the nose suction head assembly 100, the suction device 300 can suck the gas in the liquid storage cavity 11 to reduce the air pressure in the liquid storage cavity 11. At this time, the liquid in the nasal cavity can enter the liquid storage cavity 11 under the action of the air pressure difference and be stored. When cleaning the nose suction head assembly 100, it is only necessary to remove the nose suction head 30 from the liquid storage tank 10 for cleaning. The nasal care device 1000 has a simple structure and is easy to clean.

[0078] Please combine Figure 2 In some embodiments, the nose suction head assembly 100 is detachably connected to the suction device 300, and the suction device 300 includes a suction port 301, and the suction port 301 of the suction device 300 is sealed and connected to the suction port 13. When the suction port 301 is sealed and connected to the suction port 13, the gas will only flow from the liquid storage chamber 11 into the suction device 300, and will not enter the suction device 300 from the connection between the nose suction head assembly 100 and the suction device 300, so that the air pressure in the liquid storage chamber 11 will decrease rapidly, the air pressure difference between the inside and the outside is large, and the suction effect is better.
