Description

Technical Field

[0001] This invention relates to the field of nasal care technology, and more specifically to an easy-to-clean nasal care and cleaning device. Background Technology

[0002] Nasal cleaning devices are common tools used to help maintain nasal health. They clean the nasal cavity of impurities through physical cleaning, thereby moisturizing the nasal cavity and improving dryness and discomfort.

[0003] For example, Chinese patent CN119405524B discloses a pediatric nasal irrigator. The irrigator is used in conjunction with a first tube, a second tube, and a movable valve. During the irrigation interval, the movable valve prevents the first tube and the second tube from communicating with each other, and the backflowing medicine can flow into the waste liquid chamber through the second tube.

[0004] However, the commonly used squeeze-type nasal irrigator requires turning on the switch and then squeezing. After squeezing for a period of time, the internal pressure returns to normal when the switch is released, and then the switch is turned on again. This is inconvenient to operate. In addition, the irrigator plug may fall out of the nasal cavity due to the pressure.

[0005] Based on this, the present invention designs an easy-to-clean nasal cavity care and cleaning device to solve the above problems. Summary of the Invention

Multiple air guide pipes 2 are uniformly and evenly fixedly installed in a circumferential array on the conical hopper. The lower end of the air guide pipe 1 is aligned with the upper end of the air guide pipe 2. A fastening airbag 1 is fixedly installed inside the annular limiting plate, and a fastening groove is provided on the side of the annular limiting groove. The fastening airbag 1 and the fastening groove are engaged. One end of the air guide pipe is connected to one end of the diverter pipe, and the other end of the diverter pipe is connected to the fastening airbag 1. An annular isolation airbag, pre-filled with gas, is fixedly installed on the top of the storage container to separate the storage container from the air guide pipes 1.

[0011] Furthermore, the blocking assembly includes an air guide tube three and a blocking airbag. A guide groove is provided on the connector and the assembly seat, and the guide groove is connected to the fastening airbag two. The air guide tube three is fixedly connected to the replaceable cleaning tube. One end of the air guide tube three is connected to the guide groove, and an annular blocking airbag is fixedly installed on the side hole located on one side of the cleaning plug.

[0015] Compared with the prior art, the beneficial effects of this invention are as follows: 1. The separate design of the storage pot, conical hopper, and replaceable cleaning tube makes the entire cleaner easy to disassemble and clean, thus ensuring the cleanliness of the cleaner.

[0016] 2. Pressing the automatic switch seals the top opening of the storage tank, preventing air leakage during subsequent squeezing. Continued squeezing then pressurizes the air and liquid inside the tank. At this point, a fastening assembly ensures a tighter connection between the storage tank, conical hopper, and replaceable cleaning tube, preventing them from detaching due to squeezing pressure. Simultaneously, a blocking assembly further blocks the nasal cavity, preventing the cleaning plug from falling out and preventing the cleaning fluid from flowing out. This allows the cleaning fluid to flow smoothly from one side of the nasal cavity to the other under squeezing pressure, achieving cleaning. After one cleaning cycle, releasing the automatic switch allows the storage tank to automatically recover. Squeezing the automatic switch and storage tank again ensures that the pressure inside the storage tank automatically balances during breaks, facilitating the next operation and making it convenient for the user.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0022] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-5 A nasal cavity care and cleaning device that is easy to clean includes a split cleaning mechanism 1, a connecting structure 2, a leak-proof structure 3, and an automatic switching structure 4.

[0023] like Figure 2 and Figure 5 As shown, the split-type cleaning mechanism 1 includes a storage tank 11, a conical hopper 12, and a replaceable cleaning tube 13. The storage tank 11 and the conical hopper 12 are connected by a connecting structure 2. One end of the conical hopper 12 is connected to one end of the replaceable cleaning tube 13 by the connecting structure 2. The other end of the replaceable cleaning tube 13 is fixedly equipped with a cleaning plug 131 and a baffle 132. The cleaning plug 131 has multiple side holes 133 evenly opened on its side.

[0024] like Figure 2As shown, the connection structure 2 includes a first connection component 21 and a second connection component 22. The first connection component 21 is installed on the storage container 11 and the conical hopper 12, and the second connection component 22 is installed on the conical hopper 12 and the replacement cleaning pipe 13.

[0025] like Figure 2 and Figure 4 As shown, the leak-proof structure 3 includes a structural fastening component 31 and a blocking component 32. The structural fastening component 31 is installed on the storage pot 11 and the conical hopper 12, and the blocking component 32 is installed on the conical hopper 12 and the baffle 132. An automatic switch structure 4 is installed on the storage pot 11.

[0026] In this embodiment, when the easy-to-clean nasal cavity care and cleaning device is working normally, the separate arrangement of the storage tank 11, the conical hopper 12, and the replaceable cleaning tube 13 makes the entire cleaner easy to disassemble and clean, thus ensuring the cleanliness of the cleaner. Cleaning fluid is added to the storage tank 11, and then the conical hopper 12 is connected to the storage tank 11 through the first connecting component 21, and the replaceable cleaning tube 13 is connected to the first connecting component 21 through the second connecting component 22. Then the cleaning plug 131 is inserted into one nasal cavity, and the automatic switch structure 4 is operated. Pressing the automatic switch structure 4 seals the top opening of the storage tank 11, preventing air from escaping during subsequent squeezing. Continued squeezing then pressurizes the air and liquid inside the storage tank 11. At this time, the structural fastening component 31 ensures a tighter connection between the storage tank 11, the conical hopper 12, and the replaceable cleaning tube 13, preventing them from detaching due to squeezing pressure. Simultaneously, the blocking component 32 further blocks the nasal cavity, preventing the cleaning plug 131 from falling out and preventing the cleaning fluid from flowing out. This allows the cleaning fluid to flow smoothly from one side of the nasal cavity to the other under squeezing pressure, achieving cleaning. After one cleaning cycle, releasing the automatic switch structure 4 allows the storage tank 11 to automatically return to its original position. Squeezing the automatic switch structure 4 and the storage tank 11 again ensures that the pressure inside the storage tank 11 automatically balances during breaks, facilitating the next operation and making it convenient for the user.

[0027] Example 2: In some embodiments, as a preferred embodiment of the present invention, such as... Figure 4 , Figure 6 and Figure 7As shown, the connecting component 21 includes an annular retaining plate 211, an annular connecting seat 212, and an annular limiting plate 213. The annular retaining plate 211 is fixedly installed at the bottom of the storage container 11, and the annular connecting seat 212 is fixedly installed at the top of the conical hopper 12. The outer side of the annular retaining plate 211 and the inner side of the annular connecting seat 212 are provided with mating threads. The annular limiting plate 213 is fixedly installed at the bottom of the storage container 11. An annular limiting groove 214 is opened at the top of the conical hopper 12. The annular limiting plate 213 slides in the annular limiting groove 214.

[0028] The second connecting component 22 includes a connector 221 and a combination seat 222. The connector 221 is fixedly installed at the bottom of the conical bucket 12, and the combination seat 222 is fixedly installed at the end of the replaceable cleaning tube 13. The combination seat 222 has a conformal slot that matches the connector 221. The connector 221 and the combination seat 222 are plugged into each other.

[0029] like Figures 4-7 As shown, the structural fastening assembly 31 includes an air guide pipe 311, an air guide pipe 312, a fastening airbag 313, and a diverter pipe 315. Multiple air guide pipes 311 and diverter pipes 315 are uniformly and evenly fixed in a circular array inside the storage container 11, with the upper end of the air guide pipe 311 located at the top of the storage container 11. Multiple air guide pipes 312 are uniformly and evenly fixed in a circular array on the conical hopper 12, with the lower end of the air guide pipe 311 aligned with the upper end of the air guide pipe 312. A fastening airbag 313 is fixedly installed on the inner side of the annular limiting plate 213, and a fastening groove 314 is provided on the side of the annular limiting groove 214; the fastening airbag 313 and the fastening groove 314 are snapped together; the lower side of the air guide pipe 311 is connected to one end of the diversion pipe 315, and the other end of the diversion pipe 315 is connected to the fastening airbag 313; an annular isolation airbag is fixedly installed on the top of the storage tank 11 to separate the inside of the storage tank 11 from the air guide pipe 311, and the isolation airbag is pre-filled with gas.

[0030] The structural fastening assembly 31 also includes a second fastening airbag 316, which is fixedly installed on the connector 221. The lower end of the second air duct 312 is connected to the upper end of the connector 221.

[0031] The blocking assembly 32 includes an air guide tube 322 and a blocking airbag 323. A guide groove 321 is provided on the connector 221 and the assembly seat 222. The guide groove 321 is connected to the fastening airbag 316. The air guide tube 322 is fixedly connected to the replaceable cleaning tube 13. One end of the air guide tube 322 is connected to the guide groove 321. An annular blocking airbag 323 is fixedly installed on the side hole 133 on one side of the cleaning plug 131. The other end of the air guide tube 322 is connected to the blocking airbag 323.

[0032] like Figure 8As shown, the automatic switch structure 4 includes an opening and closing component and a self-resetting operation component. The opening and closing component is installed on the storage tank 11, and the self-resetting operation component is installed on the storage tank 11.

[0033] The opening and closing assembly includes a blocking block 42 and a guide rod 44. The top of the storage tank 11 is provided with an air inlet channel 41 and a moving groove 43. The moving groove 43 is located on one side of the air inlet channel 41. The blocking block 42 for blocking the air inlet channel 41 is slidably installed in the moving groove 43. The guide rod 44 is symmetrically fixed on the blocking block 42. The guide rod 44 is slidably connected to the storage tank 11. The self-resetting operation component includes a pressure plate 45 and a reset spring 46. The outer end of the guide rod 44 passes through the storage tank 11 and is fixedly connected to the upper end of the pressure plate 45. The guide rod 44 is fitted with a reset spring 46. One end of the reset spring 46 is fixedly connected to the storage tank 11, and the other end of the reset spring 46 is fixedly connected to the pressure plate 45.

[0034] In this embodiment, when the split cleaning mechanism 1, connecting structure 2, leak-proof structure 3, and automatic switch structure 4 are working normally, cleaning fluid is added to the storage tank 11. Then, the annular retaining plate 211 at the bottom of the storage tank 11 and the annular connecting seat 212 on the conical hopper 12 are threaded together. At this time, the annular limiting plate 213 is located in the annular limiting groove 214. The connector 221 and the combination seat 222 are inserted to connect one end of the conical hopper 12 and the replaceable cleaning tube 13 together. At this time, the storage tank 11, the conical hopper 12, and the replaceable cleaning tube 13 are inverted. The liquid pressure inside the storage tank 11 squeezes the isolation airbag inside the storage tank 11, thereby causing gas to flow through the first air guide pipe 311, the second air guide pipe 312, and the diversion pipe 315 into the first fastening airbag 313 and the second fastening airbag 316. This causes the first fastening airbag 313 to be inserted into the fastening groove 314, and the second fastening airbag 316 to expand. This makes the connection between the annular limiting plate 213 and the annular limiting groove 214 tighter, and the connection between the combination seat 222 and the connector 221 tighter, thereby preventing the storage tank 11, the conical hopper 12, and the replacement cleaning pipe 13 from separating. Then, the cleaning plug 131 is inserted into one nostril, and the pressure plate 45 is pressed. The pressure plate 45 moves the guide rod 44, thereby moving the block 42 horizontally. The block 42 seals the air inlet channel 41, preventing subsequent compression from causing air or liquid in the storage tank 11 to flow out of the air inlet channel 41. At this time, the return spring 46 is compressed. Then, the pressure plate 45 is pressed to pressurize the air and liquid in the storage tank 11. The pressure in the storage tank 11 increases, causing some gas to flow further through the guide groove 321 and the air guide tube 322 into the blocking airbag 323. The blocking airbag 323 expands, thereby preventing the cleaning... The plug 131 is dislodged from the nasal cavity, simultaneously blocking the flow of cleaning fluid, allowing the cleaning fluid to flow smoothly from one side of the nasal cavity to the other under the action of squeezing pressure. After one cleaning is completed, the pressure plate 45 is released, and the return spring 46 returns to its original position, driving the pressure plate 45, guide rod 44, and plug 42 to return to their original positions, causing the plug 42 to disengage from the air inlet channel 41. External gas enters the storage tank 11 through the air inlet channel 41, restoring the pressure inside the storage tank 11 to the same level as the outside pressure, and then the pressure plate 45 and storage tank 11 are squeezed again. This allows the pressure inside the storage tank 11 to automatically balance during the interval between uses, making it convenient for the user to directly proceed with the next operation.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
