Description

Technical Field

[0001] This invention relates to the field of nasal cavity cleaning technology, and in particular to a nasal irrigator. Background Technology

[0002] Nasal irrigators are commonly used nasal cavity cleaning and care devices. Nasal irrigators with detachable handles have become mainstream products due to their flexibility and adaptability. In existing detachable handle nasal irrigators, the handle is connected to the main body via a pipe. When not in use, the user needs to insert the water pipe directly into the socket that secures the handle. This storage method is cumbersome and inconvenient. Furthermore, during storage, the water pipe is prone to bending, jamming, and tangling, resulting in low storage efficiency and potential pipe damage, affecting the product's stability and lifespan. Summary of the Invention

[0003] The main objective of this invention is to provide a nasal irrigator that solves the problem of inconvenient storage of the water pipe in existing nasal irrigators.

The handle is detachably disposed on the main unit. The connecting tube has a first channel and a second channel. The first channel connects the clean water nasal irrigation head and the clean water device, and the second channel connects the return water nasal irrigation head and the wastewater device. A winding mechanism, rotatably mounted on the main unit, is provided to wind or unwind the connecting tube so that the handle can be mounted on or detached from the main unit.

[0005] In one embodiment, the host further includes a connection connector disposed within the housing, the connection connector having a first sub-channel and a second sub-channel; The winding mechanism includes: A winding connector is rotatably mounted on the connecting connector, and the winding connector has a first water passage and a second water passage; the purified water nasal rinse, the first passage, the first water passage, the first sub-channel, and the purified water component are connected in sequence; the return water nasal rinse, the second passage, the second water passage, the second sub-channel, and the wastewater component are connected in sequence. An operating component, located on the housing and connected to the take-up connector, is used to drive the take-up connector to rotate.

[0006] In one embodiment, the winding mechanism further includes a first rotating component and a second rotating component, which are rotatable relative to each other. The first rotating component abuts against the operating component, and the second rotating component abuts against the connecting joint, thereby reducing the rotational resistance of the operating component.

[0007] In one embodiment, the connecting joint is connected to the winding joint on the side away from the water purification component and the wastewater component. The winding joint and the connecting joint are plug-in mating. At least one sealing element is also provided between the winding joint and the connecting joint, and the winding joint and the connecting joint are sealed together by the sealing element.

[0008] In one embodiment, the operating component includes: A turntable is provided on the winding joint; A rotating component, at least partially exposed outside the main unit, is engaged with the turntable. The turntable is provided with an arc-shaped connecting part on the side facing the rotating component. The turntable, the arc-shaped connecting part and the rotating component enclose an assembly cavity with one end open. At least part of the winding joint is provided in the assembly cavity. The connection port of the winding connector and the connecting pipe is positioned facing the opening of the assembly cavity.

[0009] In one embodiment, the connecting pipe includes an integrally connected pipe body section and a branch section, the pipe body section being used to connect the winding connector; The pipe section includes a first pipe section and a second pipe section, and the branching section includes a first branch pipe and a second branch pipe arranged at intervals. The first pipe section and the first branch pipe are connected to form the first channel, and the second pipe section and the second branch pipe are connected to form the second channel.

[0010] In one embodiment, the water purification assembly includes a water purification tank and a water purification pump connected in communication, and the wastewater assembly includes a wastewater tank and a wastewater pump connected in communication. The water purification pump is connected to the first channel, and the wastewater pump is connected to the second channel. The water purification tank and the wastewater tank are detachably disposed on one side of the housing, and the other side of the housing has a receiving cavity. The handle is disposed on the housing at the upper end of the receiving cavity.

[0011] In one embodiment, a fixing frame is provided inside the receiving cavity, which divides the receiving cavity into a first chamber and a second chamber. The water purification pump and the sewage pump are located in the first chamber, the winding mechanism is located in the second chamber, and the connecting pipe is at least partially accommodated in the second chamber and separated from the water purification pump and the sewage pump by the fixing frame.

[0012] In one embodiment, the winding mechanism further includes a conductive component, the conductive component comprising: A conductive PCB board is disposed inside the housing and electrically connected to the water purification component and the wastewater component respectively. The conductive PCB board is provided with mutually insulated positive conductive tracks and negative conductive tracks. A conductive connection assembly is disposed on the winding mechanism and electrically connected to the handle, the conductive connection assembly including a positive connection terminal and a negative connection terminal; The positive terminal is slidably disposed on the turntable of the winding mechanism and elastically contacts the positive conductive track, and the negative terminal is slidably disposed on the turntable of the winding mechanism and elastically contacts the negative conductive track, so that the handle can be kept in a conductive connection with the water purification component and the wastewater component.

[0013] In one embodiment, the winding mechanism includes a turntable with an arc-shaped locking groove. The arc-shaped locking groove has at least two fixing holes, and the positive terminal and the negative terminal are respectively disposed in the two fixing holes. The arc-shaped locking groove contains an adhesive for fixing the positive terminal and the negative terminal.

[0014] The nasal irrigator of this application features a rotatable winding mechanism on the main unit. This mechanism winds and releases the connecting tube, allowing users to easily wind the tube into the main unit and secure the handle after use by simply rotating the winding mechanism. During use, the tube can be smoothly released to detach the handle, eliminating the tedious manual tube insertion and significantly improving ease of use. Simultaneously, the winding mechanism guides the connecting tube along a predetermined trajectory during winding, effectively preventing bending, jamming, or tangling, reducing the risk of tube damage, and ensuring product stability and lifespan. Furthermore, neatly winding the tube within the main unit results in a more compact storage configuration, facilitating storage and portability. This solves the technical problems of inconvenient tube storage, easy bending and jamming, and easy tube damage in existing nasal irrigators, achieving a balance between ease of use and structural reliability.

[0022] Please see Figures 1 to 4 In one embodiment of the present invention, a nasal irrigator is provided for nasal cavity cleaning. The nasal irrigator includes a main unit, a nasal irrigation head assembly 200, and a winding mechanism 300. The main unit includes a housing 110 and a water purification assembly 120 and a wastewater assembly 130 disposed on the housing 110. The nasal irrigation head assembly 200 includes a handle 220, a connecting tube 210, and a water purification head and a return water head disposed on the handle 220. The handle 220 is detachably disposed on the main unit. The connecting tube 210 has a first channel 211 and a second channel 212. The first channel 211 connects the water purification head and the water purification assembly 120, and the second channel 212 connects the return water head and the wastewater assembly 130. The winding mechanism 300 is rotatably disposed on the main unit to wind or release the connecting tube 210, so that the handle 220 can be installed on the main unit or detached from the main unit.

[0023] In this embodiment, a water purification component 120 and a wastewater component 130 are provided on the housing 110. The water purification component 120 is used to contain and transport the liquid required for nasal cavity cleaning, while the wastewater component 130 is used to collect and store the wastewater generated after cleaning. Optionally, the water purification component 120 and the wastewater component 130 include a detachable water tank structure that can be independently installed, as well as a driving component such as a water pump, to meet the liquid transportation requirements.

[0024] The nasal irrigation head assembly 200, which is the part that comes into direct contact with the user's nasal cavity, includes a handle 220, a connecting tube 210, and a clean water nasal irrigation head and a return water nasal irrigation head installed on the handle 220. The handle 220 can be detachably installed on the main unit, that is, the user can remove the handle 220 from the main unit or reattach it to the main unit as needed.

[0025] Optionally, the connecting tube 210 is a flexible tube made of a soft material with good flexibility and appropriate strength. In this embodiment, the connecting tube 210 has a first channel 211 and a second channel 212 that are isolated from each other along its length. One end of the first channel 211 is connected to the purified water nasal irrigation tip, and the other end is connected to the purified water component 120 of the main unit. One end of the second channel 212 is connected to the return water nasal irrigation tip, and the other end is connected to the wastewater component 130 of the main unit. Thus, when the nasal irrigator is started, the cleaning fluid in the purified water component 120 flows sequentially through the first channel 211 and the purified water nasal irrigation tip and enters the nasal cavity. After rinsing, the waste liquid flows back to the wastewater component 130 sequentially through the return water nasal irrigation tip and the second channel 212, realizing the cycle of cleaning and recycling.

[0026] In this embodiment, the winding mechanism 300 is rotatably mounted on the main unit, and the middle part of the connecting tube 210 is wound around the winding mechanism 300. The winding mechanism 300 can wind or unwind the connecting tube 210 by rotating in the forward or reverse direction.

[0027] For example, when a user needs to store the nasal irrigator, the winding mechanism 300 is driven to rotate in the first direction, and the connecting tube 210 is neatly wound around the winding mechanism 300. At the same time, the handle 220 can be moved closer and fixed to a preset position on the main unit. When the user needs to use the nasal irrigator, the handle 220 is pulled directly, and the winding mechanism 300 rotates in the opposite second direction under the action of external force. The connecting tube 210 can be released from the winding mechanism 300, and the handle 220 can be easily removed from the main unit.

[0028] The nasal irrigator in this embodiment features a rotatable winding mechanism 300 on the main unit. This mechanism winds or releases the connecting tube 210, allowing the user to simply drive the winding mechanism 300 to rotate after use, neatly winding the connecting tube 210 into the main unit and securing the handle 220. During use, the connecting tube 210 can be smoothly released to detach the handle 220, avoiding the tedious manual tube insertion and significantly improving ease of use. Simultaneously, the winding mechanism 300 guides the connecting tube 210 along a predetermined trajectory during winding, effectively preventing bending, jamming, or tangling, reducing the risk of pipe damage, ensuring product stability and lifespan. Furthermore, neatly winding the connecting tube 210 within the main unit makes storage more compact, facilitating storage and portability. This solves the technical problems of inconvenient pipe storage, easy bending and jamming, and easy pipe damage in existing nasal irrigators, achieving a balance between ease of use and structural reliability.

[0029] In one embodiment, the main unit further includes a connecting connector 330, which is disposed within the housing 110. The connecting connector 330 has a first sub-channel 331 and a second sub-channel 332. The winding mechanism 300 includes a winding connector 320 and an operating component. The winding connector 320 is rotatably disposed on the connecting connector 330 and has a first water passage 321 and a second water passage 322. The purified water nasal rinse, the first channel 211, the first water passage 321, the first sub-channel 331, and the purified water component 120 are sequentially connected. The returned water nasal rinse, the second channel 212, the second water passage 322, the second sub-channel 332, and the wastewater component 130 are sequentially connected. The operating component is disposed on the housing 110 and connected to the winding connector 320 for driving the winding connector 320 to rotate.

[0030] It is understood that the connecting joint 330 is fixed to the housing 110 or the fixing structure inside the housing 110 by means of a snap or screw.

[0031] For example, one end of the take-up connector 320 has a shaft hole that matches the outer diameter of the connecting connector 330, allowing the take-up connector 320 to rotate freely relative to the connecting connector 330.

[0032] In this embodiment, the first water passage 321 and the second water passage 322 inside the winding joint 320 are respectively connected to the first sub-channel 331 and the second sub-channel 332 of the connecting joint 330; when the winding joint 320 rotates, the water passage can still remain unobstructed because the mating surfaces between the two are provided with an appropriate sealing structure.

[0033] In this embodiment, the cleaning fluid flowing out of the water purification component 120 flows sequentially through the first sub-channel 331 of the connecting joint 330, the first water passage 321 of the winding joint 320, and the first channel 211 of the connecting pipe 210, and finally reaches the clean water nasal rinse tip; the waste liquid collected from the return water nasal rinse tip flows sequentially through the second channel 212 of the connecting pipe 210, the second water passage 322 of the winding joint 320, and the second sub-channel 332 of the connecting joint 330, and finally returns to the wastewater component 130; thus, the entire water circuit forms a complete flushing and recycling loop.

[0034] In this embodiment, the operating component is disposed on the housing 110; optionally, the operating component is partially exposed outside the housing 110 for the user to hold or manipulate, and is mechanically connected to the take-up connector 320. The user can drive the take-up connector 320 to rotate relative to the connecting connector 330 through the operating component. When the take-up connector 320 rotates, the connecting tube 210 wound around it is wound or released accordingly, thereby realizing the storage and pulling out of the connecting tube 210.

[0035] It is understandable that, through the above-described structure, the rotatable engagement of the connecting joint 330 and the winding joint 320 in this embodiment achieves the transition between the fixed water path and the rotating water path, ensuring the sealing and conduction of the water path, and allowing the connecting pipe 210 to be neatly stored as the winding joint 320 rotates, further improving the reliability and storage convenience of the nasal irrigator.

[0036] In one embodiment, the winding mechanism 300 further includes a first rotating component and a second rotating component, which are rotatable relative to each other. The first rotating component abuts against the operating component, and the second rotating component abuts against the connecting joint, thereby reducing the rotational resistance of the operating component.

[0037] For example, the first rotating component is the outer ring of the bearing 350, and the second rotating component is the corresponding inner ring, with rolling balls disposed between them, thereby allowing low-friction relative rotation between the first rotating component and the second rotating component.

[0038] During installation, one end face of the first rotating component contacts and is fixed or abuts against a corresponding part of the operating component; one end face of the second rotating component contacts and is fixed or abuts against a corresponding part of the connecting joint 330. When the user drives the operating component to rotate, the operating component drives the first rotating component to rotate relative to the second rotating component. Since the friction between the first and second rotating components is rolling friction, its coefficient of friction is much smaller than that of sliding friction, thus significantly reducing the rotational resistance experienced by the operating component.

[0039] In this way, the rotation of the winding mechanism 300 is easier and smoother. Users only need to apply a small force to drive the winding connector 320 to rotate, thereby easily winding or releasing the connecting tube 210. At the same time, the low-friction rotation also reduces wear between the operating components and the connecting connector 330, extends the service life of the winding mechanism 300, and further optimizes the rotation experience of the winding operation.

[0040] In one embodiment, the side of the connecting joint 330 away from the water purification component 120 and the wastewater component 130 is connected to the winding joint 320. The winding joint 320 and the connecting joint 330 are plug-in mating. At least one sealing element 340 is also provided between the winding joint 320 and the connecting joint 330, and the winding joint 320 and the connecting joint 330 are sealed together by the sealing element 340.

[0041] In this embodiment, the connecting connector 330 is fixedly installed inside the housing 110. The connecting connector 330 has a plug hole on the side away from the water purification component 120 and the wastewater component 130. Correspondingly, one end of the winding connector 320 is provided with a plug that matches the plug hole of the connecting connector 330. The winding connector 320 is rotatably fitted into the plug hole of the connecting connector 330 through the plug, forming a plug-in fit.

[0042] For example, after the connector is inserted into the socket, there is a clearance fit between the two to ensure that the retractor 320 can rotate freely relative to the connector 330.

[0043] To prevent liquid leakage from the mating gap between the connecting joint 330 and the winding joint 320, at least one sealing element 340 is provided between the connecting joint 330 and the winding joint 320 in this embodiment.

[0044] For example, the seal 340 is an O-ring, installed in the annular sealing groove on the outer circumferential surface of the connecting joint 330, or in the annular groove 371 on the inner wall of the insertion hole of the take-up joint 320. The seal 340 is pressed between the opposing surfaces of the connecting joint 330 and the take-up joint 320 to form a radial seal. When the take-up joint 320 rotates, the seal 340 maintains elastic contact with the opposing surface, thereby preventing liquid from leaking outward. Through the sealing effect of the seal 340, the cleaning fluid flowing from the water purification component 120 to the take-up joint 320 and the waste liquid returning from the take-up joint 320 to the sewage component 130 are both confined in the internal channel and will not leak into the housing 110.

[0045] Furthermore, at least one annular sealing groove is provided on the outer peripheral surface of the plug part, and a first sealing element is installed in the sealing groove; when the plug part of the winding connector 320 is inserted into the insertion hole of the connecting connector 330, the first sealing element elastically abuts against the inner wall of the insertion hole of the connecting connector 330 to form a radial seal, which is used to prevent liquid from leaking from the mating gap between the two when the winding connector 320 rotates.

[0046] Meanwhile, a second seal is provided on the outer side of the connecting joint 330. Exemplarily, another annular sealing groove is formed on the outer peripheral surface of the connecting joint 330, and the second seal is installed in the sealing groove and elastically abuts against the inner wall of the second rotating component to further maintain the seal.

[0047] In one embodiment, the operating component includes a turntable 360 ​​and a rotating member 310. The turntable 360 ​​is disposed on the take-up connector 320. At least a portion of the rotating member 310 is exposed outside the main unit, and the rotating member 310 is engaged with the turntable 360. The turntable 360 ​​has an arc-shaped connecting portion 361 on the side facing the rotating member 310. The turntable 360, the arc-shaped connecting portion 361, and the rotating member 310 enclose an assembly cavity 362 with one end open. At least a portion of the take-up connector 320 is disposed within the assembly cavity 362. The connection port of the take-up connector 320 and the connecting pipe 210 is oriented towards the opening of the assembly cavity 362.

[0048] For example, the turntable 360 ​​is integrated with the winding connector 320 by ultrasonic welding, snap-fitting or keyway engagement, so that the turntable 360 ​​can drive the winding connector 320 to rotate synchronously.

[0049] For example, the turntable 360 ​​is provided with a buckle, the rotating part 310 is provided with a corresponding slot, or the two are fixedly connected by an interference fit, thereby transmitting the user's driving force to the turntable 360.

[0050] In this embodiment, the arc-shaped connecting part 361 can be selected as an annular flange or an arc-shaped rib extending axially from the end face of the turntable 360. The turntable 360, the arc-shaped connecting part 361, and the rotating component 310 together enclose an assembly cavity 362 with one open end. The arc-shaped connecting part 361 is located between the turntable 360 ​​and the rotating component 310, and the space enclosed by the three is the assembly cavity 362. One end of the assembly cavity 362 is an open end, facing the interior of the turntable 360 ​​or the rotating component 310. At least a portion of the winding connector 320 is accommodated within the assembly cavity 362, thereby providing effective space for the winding connector 320 to be accommodated and protected.

[0051] In this embodiment, the connection port of the take-up connector 320 and the connecting tube 210 is positioned facing the opening of the assembly cavity 362. It can be understood that the connecting tube 210 can be led out from the connection port of the take-up connector 320, pass through the opening of the assembly cavity 362, extend outwards, and then be wound onto the turntable 360 ​​or the take-up connector 320. In this embodiment, the assembly cavity 362 provides clearance for the rotation of the take-up connector 320 and also provides a guide channel for the lead-out of the connecting tube 210, preventing the connecting tube 210 from interfering with other components during the winding process.

[0052] Furthermore, on the side of the turntable 360 ​​facing the rotating member 310, a locking part 364 is provided at intervals along the radial direction of the arc-shaped connecting part 361.

[0053] Optionally, the locking part 364 is arc-shaped. In this embodiment, the curvature of the locking part 364 is approximately the same as that of the arc-shaped connecting part 361, and the two are arranged concentrically, forming an annular guide gap between the arc-shaped connecting part 361 and the locking part 364.

[0054] During the winding process, the first turn of the connecting tube 210 closest to the center of the turntable 360 ​​is housed in the guide gap between the arc-shaped connecting part 361 and the locking part 364; as winding continues, the subsequent turns of the connecting tube 210 are wound in sequence around the radial outer side of the locking part 364, that is, the turns of the connecting tube 210 are arranged in layers radially outward, and the locking part 364 plays a role in limiting and separating the first turn of the connecting tube 210.

[0055] By setting the locking part 364, the first ring of connecting pipe 210 is radially separated from the subsequent rings of connecting pipe 210, preventing the inner pipe from sliding radially outward or intertwining with the outer pipe during the winding process, thereby ensuring the orderliness and neatness of the winding of the connecting pipe 210 and further improving the reliability of the winding mechanism 300.

[0056] In one embodiment, the connecting pipe 210 includes an integrally connected pipe body section 213 and a branch section 214. The pipe body section 213 is used to connect the winding connector 320. The pipe body section 213 includes a first pipe section and a second pipe section. The branch section 214 includes a first branch pipe 215 and a second branch pipe 216 spaced apart. The first pipe section and the first branch pipe 215 are connected to form the first channel 211. The second pipe section and the second branch pipe 216 are connected to form the second channel 212.

[0057] In this embodiment, the tube section 213 is used to connect to the winding connector 320, and the forked section 214 is used to connect the clean water nasal rinse tip and the return water nasal rinse tip on the handle 220, respectively. Optionally, the tube section 213 and the forked section 214 are integrally molded parts made of flexible material. Exemplarily, the tube section 213 and the forked section 214 are made into a whole by extrusion or injection molding processes to ensure the reliability and sealing of the connection.

[0058] The pipe section 213 further includes a first pipe section and a second pipe section. These two pipe sections can be selected as two independent pipes arranged side by side, or as two isolated chambers within the same double-lumen pipe. The first pipe section forms part of the first channel 211, and the second pipe section forms part of the second channel 212.

[0059] In this embodiment, the first pipe section and the first branch pipe 215 together form the first channel 211, which connects the purified water nose wash and the purified water component 120; the second pipe section and the second branch pipe 216 together form the second channel 212, which connects the return water nose wash and the sewage component 130.

[0060] During assembly, the ends of the first and second pipe sections are integrated into a double-hole interface for insertion and mating with the two water passages on the winding connector 320 to achieve a sealed connection. The branch section 214 branches off from the end of the pipe body section 213 into two independent hoses, which are respectively connected to the clean water nasal rinse head and the return water nasal rinse head on the handle 220. In this way, the connecting pipe 210 can maintain a compact double-cavity integrated structure on the side near the winding connector 320, which is convenient for winding and sealing connection, and can also naturally branch on the side near the handle 220 to accommodate the separate arrangement of the two nasal rinse heads on the handle 220.

[0061] Compared to two completely independent hoses, in this embodiment, by setting the tube body section 213 as an integral structure, the part of the connecting tube 210 connected to the winding connector 320 is more compact and has more consistent flexibility. It is less likely to cause relative misalignment or tangling during winding, thereby effectively improving the smoothness and reliability of the winding mechanism 300.

[0062] In one embodiment, the water purification assembly 120 includes a water purification tank 121 and a water purification pump connected in communication, and the wastewater assembly 130 includes a wastewater tank 131 and a wastewater pump connected in communication. The water purification pump is connected to the first channel 211, and the wastewater pump is connected to the second channel 212. The water purification tank 121 and the wastewater tank 131 are detachably disposed on one side of the housing 110, and the other side of the housing 110 has a receiving cavity. The handle 220 is disposed on the housing 110 at the upper end of the receiving cavity.

[0063] The clean water tank 121 is used to store the liquid required for cleaning, and the clean water pump is used to pump the liquid out of the clean water tank 121; the wastewater tank 131 is used to collect the waste liquid after cleaning, and the wastewater pump is used to pump the waste liquid from the nasal rinse assembly 200 back to the wastewater tank 131; the outlet of the clean water pump is connected to the first channel 211 of the connecting pipe 210, and the inlet of the wastewater pump is connected to the second channel 212 of the connecting pipe 210.

[0064] For example, the side of the housing 110 is provided with a recessed mounting groove, and the clean water tank 121 and the wastewater tank 131 are inserted into the mounting groove in a side-by-side or stacked manner. They are detachably fixed by a button locking structure, which makes it convenient for users to add water and pour out waste liquid.

[0065] The other side of the housing 110 has a receiving cavity for accommodating the winding mechanism 300 and the connecting tube 210; the handle 220 is disposed on the housing 110 at the upper end of the receiving cavity. Exemplarily, a handle 220 placement part is provided on the housing 110 above the receiving cavity, the handle 220 placement part is fitted with the shape of the handle 220, and the handle 220 can be inserted or snapped into this position when not in use, making the overall structure compact.

[0066] For example, the housing 110 has a structure that is generally divided into left and right sections. The left side of the housing 110 is provided with a removable fresh water tank 121 and a wastewater tank 131, arranged side-by-side and locked by a button, facilitating water filling and emptying operations from the same side. The right side of the housing 110 is provided with a handle 220 placement area and a receiving cavity located below the handle 220 placement area. The handle 220 placement area is recessed, its inner contour conforming to the shape of the handle 220, allowing the handle 220 to be independently... The handle 220 is inserted vertically or horizontally into the placement part of the handle 220 for stable positioning. A threading hole is provided on the bottom or rear wall of the placement part of the handle 220. The connecting tube 210 passes through the threading hole and extends upward or forward to connect to the handle 220. At least part of the receiving cavity is located directly below the placement part of the handle 220, and the winding mechanism 300 is installed in the receiving cavity, so that after the connecting tube 210 is led out from the winding mechanism 300 in the receiving cavity, it enters the placement part of the handle 220 through the threading hole and connects to the handle 220.

[0067] In one embodiment, a fixing frame 370 is provided in the receiving cavity, which divides the receiving cavity into a first chamber and a second chamber. The water purification pump and the sewage pump are located in the first chamber, the winding mechanism 300 is located in the second chamber, and the connecting pipe 210 is at least partially accommodated in the second chamber and separated from the water purification pump and the sewage pump by the fixing frame 370.

[0068] For example, the receiving cavity is located in the right side region of the housing 110, and a fixing frame 370 is fixedly installed inside it. Fixed to the inner wall of the housing 110 by clips or screws, the fixing frame 370 divides the receiving cavity into two relatively independent first chambers and second chambers in the horizontal direction; a clean water pump and a sewage pump are installed in the first chamber, and the pipe interfaces of these two pumps are respectively connected to the connecting joint 330 and the water tank; a winding mechanism 300 is installed in the second chamber, including components such as a winding joint 320 and a turntable 360; the connecting pipe 210 is wound on the winding mechanism 300 and is at least partially accommodated in the second chamber.

[0069] The wall of the fixed frame 370 acts as a physical barrier, completely separating the winding mechanism 300 and the connecting pipe 210 from the clean water pump and the sewage pump. In this way, when the winding mechanism 300 rotates to wind up and unwind the connecting pipe 210, the connecting pipe 210 is always confined in the second chamber and will not touch or get tangled in the water pump and related wires and water pipes in the first chamber. At the same time, the vibration generated when the water pump is working will not be directly transmitted to the connecting pipe 210, reducing the impact of vibration on the winding stability.

[0070] In this embodiment, by setting the fixing frame 370, the functional divisions within the storage cavity are clearer, and the water pump and the winding mechanism 300 do not interfere with each other, which not only ensures the smooth and reliable winding action, but also facilitates assembly and maintenance, further improving the structural rationality and operational stability of the whole machine.

[0071] In one embodiment, the winding mechanism 300 further includes a conductive component, which includes a conductive PCB board 380 and a conductive connection component 365. The conductive PCB board 380 is disposed within the housing 110 and electrically connected to the water purification component 120 and the wastewater component 130, respectively. The conductive PCB board 380 is provided with mutually insulated positive and negative conductive tracks. The conductive connection component 365 is disposed on the winding mechanism 300 and electrically connected to the handle 220. The conductive connection component 365 includes a positive connection terminal and a negative connection terminal. The positive connection terminal is slidably disposed on the turntable 360 ​​of the winding mechanism 300 and elastically contacts the positive conductive track. The negative connection terminal is slidably disposed on the turntable 360 ​​of the winding mechanism 300 and elastically contacts the negative conductive track, so that the handle 220 remains electrically connected to the water purification component 120 and the wastewater component 130.

[0072] For example, the conductive PCB board 380 is fixed to the mounting bracket 370 inside the housing 110 by screws, or is snapped onto the inner wall of the housing 110 by a snap-fit ​​structure.

[0073] In this embodiment, the conductive PCB board 380 is electrically connected to the water purification component 120 and the sewage component 130 respectively via wires, that is, it is connected to the control terminals of the water purification pump and the sewage pump; the surface of the conductive PCB board 380 is provided with two concentrically distributed and mutually insulated annular conductive tracks, wherein the inner track is the positive conductive track and the outer track is the negative conductive track.

[0074] A conductive connection assembly 365 is mounted on the winding mechanism 300 and electrically connected to the handle 220. The conductive connection assembly 365 includes a positive connection terminal and a negative connection terminal. Exemplarily, the positive and negative connection terminals are fixed to the turntable 360 ​​of the winding mechanism 300 by an interference fit or snap-fit, and rotate together with the turntable 360. Two mounting holes may be provided on the turntable 360, and the two connection terminals are respectively inserted into the corresponding mounting holes so that their contact ends face the conductive track of the conductive PCB board 380.

[0075] The positive terminal slides into contact with the positive conductive track, and the negative terminal slides into contact with the negative conductive track. For example, each terminal has a spring inside, ensuring that its contact end always presses against the surface of the corresponding conductive track with elastic pressure, thereby maintaining a reliable electrical connection during the 360-degree rotation of the turntable.

[0076] Through the setting of this conductive component, the electrical signal on the handle 220 is transmitted sequentially through the internal wires of the handle 220, the positive and negative connection terminals on the turntable 360, and the conductive track on the conductive PCB board 380 to the water purification component 120 and the wastewater component 130, thereby realizing the control of the water pump; at the same time, the voltage provided by the host can also power the handle 220 in reverse through the same path. Thus, during the process of the winding mechanism 300 rotating the winding and unwinding connecting tube 210, the electrical connection between the handle 220 and the host remains conductive.

[0077] In one embodiment, the winding mechanism 300 includes a turntable 360, on which an arc-shaped locking groove 363 is provided. The arc-shaped locking groove 363 is provided with at least two fixing holes, and the positive terminal and the negative terminal are respectively disposed in the two fixing holes. The arc-shaped locking groove 363 is provided with an adhesive for fixing the positive terminal and the negative terminal.

[0078] In this embodiment, the arc of the arc-shaped snap-fit ​​groove 363 matches the annular conductive track on the conductive PCB board 380. At least two fixing holes are opened at intervals along the arc direction on the bottom wall of the groove, and the number of fixing holes corresponds to the number of connecting terminals.

[0079] For example, there are two connection terminals, including a positive connection terminal and a negative connection terminal; the positive connection terminal and the negative connection terminal are respectively inserted and fixed in the two fixing holes. Optionally, the fixed end of each connection terminal is fixed to the fixing hole by interference fit or adhesive, and its elastic contact end extends out of the fixing hole to abut against the conductive track.

[0080] For example, the groove wall of the arc-shaped snap-fit ​​groove 363 forms a receiving space with a certain depth. After the positive and negative connection terminals are installed in place, potting compound is filled into the arc-shaped snap-fit ​​groove 363. After the potting compound cures, the fixed end of the connection terminal is firmly bonded to the turntable 360 ​​as one unit. At the same time, the gap between the fixing hole and the connection terminal is filled to prevent the connection terminal from axial movement or radial displacement during use. By filling and fixing with potting compound, the assembly position accuracy and stability of the connection terminal can be guaranteed without the need for additional limiting plates.

[0081] Furthermore, both the positive and negative connection terminals use spring pins (POGOPIN); the POGOPIN includes a cylindrical fixed end and a retractable plunger-shaped contact end, with a spring inside; the fixed end is pressed into the fixing hole of the turntable 360 ​​by interference fit and welded or tightly fitted, while the contact end extends elastically under the action of the spring, always abutting against the positive or negative conductive track of the conductive PCB board 380 with a preset contact pressure, thereby maintaining stable electrical contact.

[0082] Thanks to the elasticity and stretching properties of the POGOPIN itself, the two connection terminals can maintain reliable contact with the conductive tracks on the conductive PCB board 380 during the 360-degree rotation of the turntable, ensuring the reliability of the conductive connection.

[0083] In one embodiment, the fixing frame 370 is fixedly installed in the receiving cavity of the housing 110. An annular groove 371 is formed on the surface of the fixing frame 370 facing the winding mechanism 300. The conductive PCB board 380 is annular in shape and its shape matches the annular groove 371. The conductive PCB board 380 is embedded and fixed within the annular groove 371. Two concentric annular conductive tracks are provided on the side of the conductive PCB board 380 facing the turntable 360, namely a positive conductive track and a negative conductive track. A through hole is formed at the center of the fixing frame 370, and the through hole axially penetrates the fixing frame 370. A connecting joint 330 passes through the through hole and is fixedly connected to the fixing frame 370. The winding joint 320 is rotatably sleeved on the connecting joint 330 and located on the side of the fixing frame 370 facing the turntable 360.

[0084] For example, the conductive PCB board 380 is fixed to the bottom wall of the annular groove 371 by adhesive backing or snap-fit.

[0085] For example, the connecting joint 330 is fixed to the inner wall of the through hole by means of threads or snaps.

[0086] In this embodiment, the turntable 360 ​​is fixedly installed on the winding connector 320 and is located between the fixing frame 370 and the rotating component 310. There is a preset gap in the axial direction between the turntable 360 ​​and the fixing frame 370. This gap is used to accommodate the conductive PCB board 380 and to provide clearance for the rotation of the turntable 360. Two fixing holes are opened on the side of the turntable 360 ​​facing the fixing frame 370. The two fixing holes are arranged circumferentially around the turntable 360 ​​and are respectively located at radial positions corresponding to the positive conductive track and the negative conductive track on the conductive PCB board 380. A POGOPIN is fixedly installed in each fixing hole. The fixing end of the POGOPIN is fixed to the fixing hole by interference fit or adhesive. Its elastic contact end extends out of the fixing hole and extends axially toward the conductive PCB board 380.

[0087] In the assembled state, the elastic contact end of the POGOPIN passes through the gap between the turntable 360 ​​and the fixing frame 370 and abuts against the corresponding conductive track on the conductive PCB board 380 with elastic pressure; when the turntable 360 ​​rotates with the winding connector 320, the contact end of the POGOPIN slides on the annular conductive track. Since the conductive track is a continuous annular structure, the electrical connection always remains conductive at any rotation angle.

[0088] In this embodiment, the conductive components are compactly integrated into the gap between the mounting bracket 370 and the turntable 360. The conductive PCB board 380 is embedded in the annular groove 371 of the mounting bracket 370, and the POGOPIN is installed in the fixing hole of the turntable 360. The two are arranged opposite each other in the axial direction and maintain elastic contact. This layout makes full use of the limited space between the mounting bracket 370 and the turntable 360, avoids increasing the overall size of the nasal irrigator, and ensures the reliability and stability of the electrical connection during rotation.
