DETAILED DESCRIPTION

[0026] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1

[0028] like Figures 1 to 3 As shown, an ear rinsing device with a heatable rinsing solution includes a base 19. A rinsing solution recovery tank 1 is connected to the top of the base 19 via a support rod 18. A rinsing pump 7, a fixing plate 15, and a support shell 22 are connected to the side wall of the support rod 18. A buffer groove 13 is formed on the top of the fixing plate 15. A support plate 11 is connected to the buffer groove 13 via a compression spring 14. A temperature sensor 12 is embedded in the top of the support plate 11. A rinsing solution storage tank 10 is supported and connected to the top of the support plate 11. A heating plate 21 connected to the fixing plate 15 is snapped onto one side of the rinsing solution storage tank 10. The inlet is detachably connected to a sealing cap 9. The sealing cap 9 is connected through an inlet pipe 8 that is inserted into the flushing liquid storage tank 10. One end of the inlet pipe 8 is connected to the inlet of the flushing pump 7. The outlet of the flushing pump 7 is connected to an outlet pipe 6 that is inserted into the flushing liquid recovery tank 1. The insertion end of the outlet pipe 6 is connected to a flushing nozzle 4. The carrier shell 22 is connected to a mobile power supply 23, a control switch 24, and a controller 25. The flushing pump 7, temperature sensor 12, control switch 24, and controller 25 are electrically connected to the mobile power supply 23, and the flushing pump 7, temperature sensor 12, and control switch 24 are signal connected to the controller 25.

[0029] Working principle:

[0030] Temperature control principle: Temperature sensor 12 monitors the temperature of the rinsing fluid in the rinsing fluid storage tank 10 in real time and transmits the temperature signal to controller 25. When the monitored temperature is lower than the preset suitable temperature, controller 25 automatically activates heating plate 21, which heats the rinsing fluid in the rinsing fluid storage tank 10 through heat conduction. Once the temperature reaches the preset value, controller 25 immediately turns off heating plate 21. This cycle repeats precisely to maintain the rinsing fluid at a suitable temperature range close to human body temperature, ensuring that the rinsing process will not irritate the ear canal due to temperature issues.

[0031] Rinse fluid extraction and spraying principle: After the control switch 24 is turned on, the signal is transmitted to the controller 25, and the controller 25 then starts the rinsing pump 7. When the rinsing pump 7 is working, its internal impeller rotates at high speed, generating negative pressure, which causes the rinsing fluid in the rinsing fluid storage tank 10 to be drawn into the rinsing pump 7 through the inlet pipe 8 under the action of pressure difference. Then the rinsing pump 7 pressurizes the drawn-in rinsing fluid and pushes it to the rinsing nozzle 4 through the outlet pipe 6. Finally, it is sprayed out from the rinsing nozzle 4 at a certain flow rate and pressure to realize the rinsing operation of the ear canal. The rinsed liquid flows into the rinsing fluid recovery tank 1 under the action of gravity and is collected.

[0032] Example 2

[0033] like Figures 1 to 3 As shown, an ear rinsing device with a heatable rinsing solution includes a base 19. A rinsing solution recovery tank 1 is connected to the top of the base 19 via a support rod 18. A rinsing pump 7, a fixing plate 15, and a support shell 22 are connected to the side wall of the support rod 18. A buffer groove 13 is formed on the top of the fixing plate 15. A support plate 11 is connected to the buffer groove 13 via a compression spring 14. A temperature sensor 12 is embedded in the top of the support plate 11. A rinsing solution storage tank 10 is supported and connected to the top of the support plate 11. A heating plate 21 connected to the fixing plate 15 is snapped onto one side of the rinsing solution storage tank 10. The inlet is detachably connected to a sealing cap 9. The sealing cap 9 is connected through an inlet pipe 8 that is inserted into the flushing liquid storage tank 10. One end of the inlet pipe 8 is connected to the inlet of the flushing pump 7. The outlet of the flushing pump 7 is connected to an outlet pipe 6 that is inserted into the flushing liquid recovery tank 1. The insertion end of the outlet pipe 6 is connected to a flushing nozzle 4. The carrier shell 22 is connected to a mobile power supply 23, a control switch 24, and a controller 25. The flushing pump 7, temperature sensor 12, control switch 24, and controller 25 are electrically connected to the mobile power supply 23, and the flushing pump 7, temperature sensor 12, and control switch 24 are signal connected to the controller 25.

[0034] A drain pipe 2 is connected to the bottom of the flushing fluid recovery tank 1.

[0035] The advantages of the above settings are:

[0036] Convenient for waste liquid discharge

[0037] After the ear rinsing process is completed, a large amount of waste liquid will be collected in the rinsing fluid recovery tank 1. The presence of the drain pipe 2 allows the waste liquid to be discharged conveniently and quickly. The user only needs to open the drain device, such as a valve, or remove the plug, and the waste liquid will flow out naturally under the action of gravity, without the need for manual emptying of the recovery tank, thus avoiding the inconvenience caused by an excessively heavy or large recovery tank.

[0038] For example, in medical settings such as hospitals, medical staff need to use ear irrigation devices frequently. With the drain pipe 2, they can quickly clean the recovery tank after completing the irrigation of one patient, preparing for the use of the next patient, improving work efficiency.

[0039] Maintaining cleanliness

[0040] Without the drain pipe 2, the waste liquid after irrigation stays in the recovery tank 1 for a long time, which is easy to breed bacteria and odor. These bacteria may spread to the surrounding environment, posing a threat to the health of the user, and also affecting the use experience of the device.

[0041] The drain pipe 2 can timely drain the waste liquid, keeping the recovery tank 1 in a relatively dry and clean state. This helps to prevent bacterial breeding and reduce odor generation, providing a good sanitary environment for the ear irrigation device, ensuring that the device is clean and sanitary every time it is used.

[0042] Extending the service life of the device

[0043] If the waste liquid is stored in the recovery tank 1 for a long time, it may have a corrosive effect on the material of the recovery tank. For example, some irrigation liquids may contain chemical components that can react with the plastic or metal material of the recovery tank.

[0044] The drain pipe 2 timely drains the waste liquid, reducing the possibility of chemical corrosion, thereby extending the service life of the recovery tank 1 and the entire ear irrigation device, reducing the maintenance cost and replacement frequency of the equipment.

[0045] Convenient for moving and storing the device

[0046] When the recovery tank 1 is full of waste liquid, the device becomes heavy and is not easy to move. Moreover, if the waste liquid splashes during movement, it will also pollute the surrounding environment.

[0047] With the drain pipe 2, the waste liquid can be drained first, keeping the device relatively light in weight, making it convenient to move the ear irrigation device to other locations for storage or further cleaning and maintenance.

[0048] The side of the irrigation liquid recovery tank 1 is connected with a fixed pipe 3, and the irrigation nozzle 4 is movably inserted with the fixed pipe 3.

[0049] The advantages of the above arrangement are:

[0050] Convenient for storing and taking the irrigation nozzle

[0051] Convenient storage: when the ear flushing device is not in use, the flushing nozzle 4 can be inserted into the fixed tube 3 for storage. In this way, the flushing nozzle 4 has a fixed storage location, avoiding the loss or damage caused by random placement. For example, in the otolaryngology department of a hospital, medical staff can quickly insert the flushing nozzle 4 into the fixed tube 3 after completing the flushing operation, keeping the work area clean and orderly.

[0052] Convenient access: when the flushing nozzle 4 is needed, the user can easily pull it out of the fixed tube 3. This active plug-in method makes the nozzle easy and fast to access, eliminating the need to search for the nozzle in a cluttered tool, improving the efficiency of ear flushing operations.

[0053] Ensure the cleanliness and hygiene of the flushing nozzle

[0054] The fixed tube 3 provides a relatively independent and closed storage space for the flushing nozzle 4. Compared with random placement of the nozzle, insertion into the fixed tube 3 can reduce the possibility of the nozzle being contaminated by external dust, pollutants and other impurities. In a medical environment, it is very important to keep the flushing nozzle 4 clean to prevent harmful microorganisms such as bacteria from entering the ear canal through the nozzle, reducing the risk of infection.

[0055] Protect the flushing nozzle from damage

[0056] When the flushing nozzle 4 is inserted into the fixed tube 3, the fixed tube 3 can provide some protection. For example, when the device is moved or slightly bumped, the fixed tube 3 can buffer the impact force from the outside, preventing the flushing nozzle 4 from being damaged by impact. This protection is particularly important for nozzles made of brittle materials, which can extend the service life of the flushing nozzle 4.

[0057] Optimize the overall layout and space utilization of the device

[0058] By actively plugging the flushing nozzle 4 into the fixed tube 3 on the side of the flushing liquid recovery tank 1, the layout of the various components of the device is more reasonable. The flushing liquid recovery tank 1 itself is a device for collecting liquid after flushing, and the fixed position of the nozzle is set on its side, making full use of the space of the recovery tank 1, making the structure of the entire ear flushing device more compact and the appearance more neat.

[0059] The side wall of the flushing nozzle 4 is connected with a handle 5.

[0060] The advantages of the above arrangement are:

[0061] Easy to operate and control

[0062] Handheld stability: When performing ear irrigation, the user needs to accurately aim the irrigation nozzle at the ear canal. The presence of the handle 5 provides a stable grip for the user, allowing them to better control the position and orientation of the irrigation nozzle 4. For example, when a healthcare professional is irrigating a patient's ear canal, they can more precisely insert the nozzle to the appropriate depth and maintain the nozzle's stability during irrigation by holding the handle 5, avoiding accidental damage to the ear canal caused by nozzle movement.

[0063] Operational flexibility: The handle 5 allows the user to easily adjust the angle of the irrigation nozzle 4. Different patients may have different ear canal shapes and angles. By holding the handle 5, the user can easily rotate or tilt the nozzle to adapt to different ear canal conditions, ensuring that the irrigation fluid can effectively irrigate all parts of the ear canal, improving the effectiveness of the irrigation.

[0064] Enhanced user comfort

[0065] Long-term holding of the irrigation nozzle 4 can cause hand fatigue. The handle 5 is designed with ergonomic principles in mind, providing a more comfortable grip experience. The shape and material of the handle 5 are usually designed to consider the user's hand gripping characteristics, such as using non-slip materials or having a certain arc design, which can reduce the friction between the hand and the nozzle, prevent hand slipping, and make the user feel more comfortable during the entire irrigation process, even if the irrigation operation is longer, it will not be too tired.

[0066] Convenient for multiple users and different operation habits

[0067] In hospitals, clinics and other places, the ear irrigation device may be used by different healthcare professionals. The handle 5 allows different users to comfortably hold the nozzle according to their own operation habits and hand size. Moreover, for non-professionals such as patient family members assisting with irrigation, the handle 5 also makes it easier for them to operate, reducing the difficulty of operation.

[0068] The irrigation fluid storage tank 10 is a transparent product.

[0069] The advantages of the above settings are:

[0070] Easy to observe the remaining amount of irrigation fluid

[0071] Precise control of the irrigation process: During ear irrigation, the user needs to know the remaining amount of irrigation fluid to ensure that the irrigation operation can be completed smoothly. The transparent irrigation fluid storage tank 10 allows the user to directly observe the height of the internal irrigation fluid, thereby accurately determining the remaining amount. For example, when the irrigation fluid is almost used up, the user can prepare in advance, such as pausing irrigation, adding irrigation fluid, to avoid interrupting the operation due to the depletion of irrigation fluid during the irrigation process, affecting the irrigation effect.

[0072] Reasonable arrangement of flushing work: for medical staff, when performing multiple ear flushing work, it is helpful to arrange work reasonably to intuitively see the remaining amount in the flushing liquid storage tank 10. They can estimate how many patients can be flushed according to the amount of remaining flushing liquid, prepare for replenishment of flushing liquid in advance, and improve work efficiency.

[0073] Convenient to check the state of flushing liquid

[0074] Monitoring liquid quality: the transparent storage tank 10 facilitates the inspection of the quality of the flushing liquid. The user can observe whether the flushing liquid has impurities, discoloration or precipitation, etc. If the flushing liquid is found to be turbid, have foreign matter, etc., the flushing liquid can be replaced in time to prevent the use of unqualified flushing liquid to cause harm to the ear. For example, during storage, if the flushing liquid is contaminated, the user can find it at a glance through the transparent tank body, ensuring the safety of the flushing liquid.

[0075] Observing changes in liquid properties: some special flushing liquids may change in properties due to factors such as temperature and time, such as some flushing liquids containing drug components that may separate. Through the transparent storage tank 10, the user can observe these changes to determine whether the flushing liquid is still suitable for ear flushing, ensuring the effectiveness and safety of the flushing operation.

[0076] Example 3

[0077] As shown in Figures 1 to 3 , an ear flushing device that can heat the flushing liquid includes a base 19, the top of the base 19 is connected with a flushing liquid recovery tank 1 through a support rod 18, the side wall of the support rod 18 is connected with a flushing pump 7, a fixed plate 15, a bearing shell 22, the top of the fixed plate 15 is provided with a buffer groove 13, the buffer groove 13 is connected with a bearing plate 11 through a compression spring 14, the top of the bearing plate 11 is embeddedly connected with a temperature sensor 12, the top of the bearing plate 11 is loadedly connected with a flushing liquid storage tank 10, one side of the flushing liquid storage tank 10 is clamped with a heating plate 21 connected with the fixed plate 15, the liquid inlet of the flushing liquid storage tank 10 is detachably connected with a sealing cover 9, the sealing cover 9 is connected with a liquid inlet pipe 8 inserted into the flushing liquid storage tank 10, one end of the liquid inlet pipe 8 is connected with the liquid inlet of the flushing pump 7, the liquid outlet of the flushing pump 7 is connected with a liquid outlet pipe 6 inserted into the flushing liquid recovery tank 1, the inserted end of the liquid outlet pipe 6 is connected with a flushing nozzle 4, the bearing shell 22 is connected with a mobile power supply 23, a control switch 24 and a controller 25, the flushing pump 7, the temperature sensor 12, the control switch 24 and the controller 25 are electrically connected with the mobile power supply 23, the flushing pump 7, the temperature sensor 12 and the control switch 24 are signal connected with the controller 25.

[0078] The fixing plate 15 is inserted with a limiting rod 16 corresponding to the irrigation liquid storage tank 10, which is connected to the bottom side of the fixing plate 15 through a return spring 17.

[0079] The advantages of the above arrangement are:

[0080] Stable irrigation liquid storage tank

[0081] Prevent shaking: During the use of the ear irrigation device, vibrations may occur due to various reasons, such as the operation of the irrigation pump 7, the movement of the device, or the interference of the surrounding environment. The limiting rod 16 corresponds to the irrigation liquid storage tank 10 and can effectively limit the storage tank, preventing it from shaking left and right or up and down during vibration. Through the elastic support of the return spring 17, even if the device is slightly shaken, the limiting rod 16 can tightly resist the irrigation liquid storage tank 10, keeping it stable and avoiding the internal irrigation liquid from producing violent fluctuations due to the shaking of the storage tank, which in turn affects the accurate measurement of the temperature sensor 12 and the normal work of the heating plate 21.

[0082] Precise positioning: The limiting rod 16 helps to accurately position the irrigation liquid storage tank 10 on the fixing plate 15. When installing or replacing the irrigation liquid storage tank 10, users can easily place the storage tank in the correct position through the limiting rod 16, ensuring the accurate connection and cooperation of related components such as the liquid inlet pipe 8, heating plate 21, and temperature sensor 12, and guaranteeing the normal operation of the entire ear irrigation device.

[0083] Buffer protection

[0084] Reduce impact force: When the device is suddenly impacted by external force, such as being bumped or accidentally falling, the return spring 17 can act as a buffer. It can absorb part of the impact force, so that the force of the limiting rod 16 on the irrigation liquid storage tank 10 is not too strong, thereby avoiding damage to the storage tank due to excessive instantaneous impact force. This buffering mechanism effectively protects the irrigation liquid storage tank 10 and the irrigation liquid inside, reducing the risk of device damage and irrigation liquid leakage due to accidental situations.

[0085] Convenient installation and removal

[0086] Convenient user operation: The design of the limiting rod 16 and the return spring 17 makes the installation and removal of the irrigation liquid storage tank 10 more convenient. During installation, users only need to place the irrigation liquid storage tank 10 on the fixing plate 15 and press it slightly. The limiting rod 16 will automatically adjust its position and clamp the storage tank under the action of the return spring 17, completing the installation. When removing, users can lift the irrigation liquid storage tank 10 slightly to overcome the elastic force of the return spring 17 and remove the storage tank. This simple installation and removal method makes it convenient for users to clean the irrigation liquid storage tank 10, replace the irrigation liquid, or repair related components.

[0087] The bottom of the base 19 is connected with multiple groups of evenly distributed pulleys 20.

[0088] The advantages of the above arrangement are:

[0089] Convenient to move the device

[0090] Improve the flexibility of use: In different use scenarios such as hospitals, clinics or families, it may be necessary to move the ear flushing device according to the actual situation. For example, in the otolaryngology department of the hospital, medical staff may need to move the device from one treatment room to another, or transfer the equipment between the wards. The arrangement of pulleys 20 makes it easy to move the device, just need to push it gently, you can move the device to the desired location, greatly improving the flexibility of device use.

[0091] Convenient to clean and store: When the environment around the ear flushing device needs to be cleaned, or the device needs to be stored, the pulley 20 can easily move the device away. You can easily push the device to a place where cleaning tools are easily accessible, or push it to a storage space for storage, without having to carry the entire device, reducing the physical burden on the user.

[0092] Ensure the stability of the movement process

[0093] The advantages of uniform distribution: Multiple groups of evenly distributed pulleys 20 can evenly distribute the force on the base 19. When moving the device, whether it is straight or turning, it can ensure the balance and stability of the device. This can prevent the device from falling over during movement due to unstable center of gravity, protecting the device from damage, and also avoiding potential safety hazards such as leakage of flushing liquid caused by the device falling over.

[0094] Convenient for different people to operate

For example, users can determine whether the power bank 23 needs to be charged by observing the power indicator light, or check the working indicator light of the controller 25 to understand whether the device is running normally, enhancing the user's sense of control over the device.

[0107] The power bank 23 is a rechargeable lithium battery.

[0108] The advantages of the above arrangement are:

[0109] Sustainability and convenience of energy

[0110] Reusable: As a rechargeable lithium battery, the power bank 23 can be repeatedly used through charging. Compared with disposable batteries, this greatly reduces the frequency of battery replacement. In scenarios where ear irrigation devices are frequently used, such as hospital ENT departments, medical staff do not need to frequently purchase and replace batteries, saving time and cost.

[0111] Charging at any time: The charging method of lithium batteries is simple and convenient. When the power bank 23 is low on power, it can be charged using common charging equipment such as a charger. This flexibility allows the ear irrigation device to replenish energy at any place with a power outlet, ensuring the continuous availability of the device.

[0112] Environmental advantages

[0113] Reduce waste: Since rechargeable lithium batteries can be used multiple times, compared with disposable batteries, the generation of waste batteries is greatly reduced. Disposable batteries contain harmful substances such as mercury and cadmium, which can cause serious environmental pollution if not properly disposed of. Lithium batteries have relatively less environmental impact during normal use and recycling, in line with environmental concepts.

[0114] Higher energy efficiency: Lithium batteries have a high energy density, allowing them to store more electrical energy in a relatively small volume and weight. This means that while providing enough power for the ear irrigation device, the overall energy consumption of the device is reduced, improving energy efficiency and reflecting environmental friendliness from another perspective.

[0115] Performance advantages

[0116] Low self-discharge rate: The self-discharge rate of lithium batteries is relatively low, which allows the power bank 23 to maintain power for a long time when not in use. For example, when the ear irrigation device is left unused for a long time, there is no need to worry about the lithium battery quickly self-discharging and causing insufficient power for the next use. This feature ensures that the power bank 23 can provide reliable power support for the device at any time.

[0117] Output voltage stabilization: the lithium battery can provide stable output voltage for the ear irrigation device. During the ear irrigation process, stable voltage is essential for the normal work of the irrigation pump 7, the temperature sensor 12, the controller 25 and other components. Stable voltage can ensure the stable speed of the irrigation pump 7, thereby ensuring the stable flow and pressure of the irrigation liquid; at the same time, it is also helpful for the accurate work of the temperature sensor 12 and the controller 25, avoiding the situation of measurement error or control failure due to voltage fluctuation.

[0118] The examples made by the utility model are not limited to the implementation mode. For ordinary skilled persons in the art, other different forms of changes or variations can be made on the basis of the above description, and all the implementation modes do not need to be exhausted here, and the obvious changes or variations derived therefrom are still within the protection scope of the utility model.
