Description

Technical Field

[0001] The present application belongs to the technical field of medical care appliances, and relates to the technical field of nasal cleaning equipment, specifically a waterproof nasal cleaning equipment with a display and anti-liquid spillage prevention function. Background Art

[0002] There are two types of electric pumps for electric spray nasal washers in the prior art: 1. The motor usually works by pumping air, and the air inlet is usually set at the bottom of the shell. There are air inlet holes inside the shell and the outside world. In spring or humid environments, water mist or water vapor can easily flow into the movement cavity from the air inlet, causing corrosion and damage to the movement and electronic components of the control motherboard; 2. The motor usually adopts a micro-diaphragm water pump, which realizes the liquid medicine delivery function through the water pump. There is a risk of contaminating the liquid medicine when the internal parts of the water pump come into contact with the liquid medicine; and because the internal parts of the water pump are often in contact with saline or liquid medicine, the service life is reduced and the operation is unreliable. This spray is achieved by using a micro-diaphragm water pump to break up the liquid into particles. The particles formed by the water pump spray are uneven, the conversion efficiency is low, and the uniformity of the particles after mixing achieved by using the Venturi effect cannot be achieved.

[0003] The problem with the electric spray nasal irrigators currently on the market is that different working modes and functions are usually displayed by indicating whether the indicator light is always on, flashing, or the color of the light. For first-time users or the elderly and children, it is easy for them to not understand the working modes and functions clearly, resulting in a confusing and bad experience. At the same time, during the use of the electric spray nasal irrigator, the waste liquid recovery device is unreasonable and it is easy for it to overflow outside the main unit, and the waste liquid is not well separated from the medicine. When in use, the waste liquid is easy to flow into the medicine tank, resulting in contamination of the medicine, affecting the efficacy of the medicine and reducing the treatment effect. Utility Model Content

[0004] The purpose of this application is to solve the above-mentioned problem that for the display of different working modes and various functions, the indicator light is usually used to indicate whether it is always on or flashing or the color of the light is used; for first-time users or the elderly and children, it is easy to have an unclear understanding of the working modes and various functions, which leads to a confusing and bad experience. A waterproof nasal cleaning device with a display and anti-drug spillage prevention is provided.

[0005] The technical solution adopted in this application is as follows: a waterproof nasal cleaning device with a display and anti-drug spillage protection, including a shell, a bottom cover, a circuit board, a battery, a lens, an air pump, a liquid storage tank, a pipette, an upper cover, a drainage cover, a nozzle, a dust cover, and a one-way valve. A display screen is provided on the upper surface of the circuit board, and the display screen and the circuit board are connected by an FPC. The lower surface of the circuit board is fixedly connected to an air pump.

[0006] By adopting the above technical solution, the battery powers both the circuit board and the display. The air pump is activated and controlled by the MCU, which also controls the display information, presenting the displayed content through the lens's visible window. The lens and the housing are secured using double-sided tape, glue, or ultrasonic connection. The display can be set using buttons to display various functions, such as operating mode, operating time, battery level, number of uses, and alarm timer. This provides a visual display that significantly enhances the user experience and improves the efficiency of information transmission.

[0007] In a preferred embodiment, a one-way valve is fixedly connected to the inner wall of the bottom cover, a venturi is fixedly connected to the inner wall of the liquid storage tank, a suction tube is sleeved on the outer wall of the venturi, and a reasonably designed gap exists between the suction tube and the venturi.

[0008] By adopting the above technical solution, when the air pump is working, the gas enters the one-way valve from the opening of the bottom cover, and then enters the inner cavity of the shell after the one-way valve opens. The gas is sucked into the motor through the air inlet of the air pump and converted inside, and then ejected from the air outlet of the air pump. When the air pump stops working, no air flow enters the inner cavity of the shell, the one-way valve is closed, and the liquid in the shell cannot enter the interior, and the one-way valve plays a blocking role.

[0009] In a preferred embodiment, the inner wall of the liquid storage bin is provided with a partition plate, the interior of the partition plate is divided into a waste liquid bin and a medicine liquid bin, and the upper cover is correspondingly provided with a U-shaped groove.

[0010] By adopting the above technical solution, when the liquid storage tank and the upper cover are assembled, the upper side wall of the liquid storage tank and the side wall of the partition plate are assembled and matched with the lower side wall of the upper cover and the U-shaped groove. The upper cover baffle is provided at the corresponding position of the upper cover and the liquid medicine tank. The clearance between the liquid storage tank and the upper cover is designed to be small. Together with the upper cover baffle, when the whole machine is tilted, it prevents the liquid from overflowing and the liquid is not easy to flow out.

[0011] In a preferred embodiment, one side of the liquid storage bin is fixedly connected to the other side of the upper cover, a drainage cover is provided on the side of the upper cover away from the liquid storage bin, a drainage groove is provided on the inner wall of the drainage cover, the upper cover and the drainage cover are combined to form a waste liquid reflux wall, and the upper cover is provided with a liquid-blocking side wall of a certain height.

[0012] By adopting the above technical solution, after the liquid spray is sprayed out and the nasal cavity is cleaned, the waste liquid flows back through two paths. The inner wall of the nozzle flows back to the inner wall of the drainage cover, and then flows into the waste liquid bin. The waste liquid flows back to the outer wall of the drainage cover through the outer wall of the nozzle, and then flows into the drainage slope, flows through the slope to the drainage groove, and flows into the waste liquid bin. When the outer wall liquid is drained, there is an upper cover baffle on the medicine liquid bin, and the waste liquid will flow from the upper cover baffle to the U-shaped groove side, and then flow into the waste liquid bin. There is no situation of flowing into the medicine liquid bin.

[0013] In a preferred embodiment, the upper side wall of the liquid storage bin and the lower side wall of the upper cover are sealed together.

[0014] By adopting the above technical solution, when the whole machine is tilted, the liquid is not easy to flow out, which prevents the liquid from overflowing and causing waste. This sealing combination can also prevent waste liquid from flowing into the liquid medicine tank, protecting the liquid medicine from being contaminated.

[0015] In a preferred embodiment, an air inlet is provided on the upper portion of the bottom cover, and a one-way valve is installed in the air inlet to communicate with the air inlet on the air pump.

[0016] By adopting the above technical solution, the one-way air intake effect of the one-way valve is achieved, and the one-way valve is closed when no air is intaken, thereby solving the problem of preventing liquid from entering the air intake hole and causing corrosion damage to the movement and control mainboard electronic components.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0018] 1. In this application, a battery powers both the circuit board and the display. The air pump is activated and controlled by an MCU, which simultaneously controls the display information, presenting the displayed content through the lens's visible window. The lens and housing are secured using double-sided tape, glue, ultrasonic connection, or other methods. The display's buttons allow for various functions to be set, including operating mode, operating time, battery level, number of uses, and alarm timer. This provides a visual display that significantly enhances the user experience and improves information transmission efficiency.

[0019] 2. In this application, after the liquid spray is sprayed and the nasal cavity is cleaned, the waste liquid flows back through two paths. The inner wall of the nozzle flows back to the inner wall of the drainage cover, and then flows into the waste liquid bin. The waste liquid flows back to the outer wall of the drainage cover through the outer wall of the nozzle, and then flows into the drainage slope, flows through the slope to the drainage groove, and flows into the waste liquid bin. When the outer wall liquid is drained, there is an upper cover baffle on the liquid medicine bin. The waste liquid will flow from the upper cover baffle to the side of the U-shaped groove, and then flow into the waste liquid bin. There is no situation of flowing into the liquid medicine bin, which can prevent the waste liquid from flowing back to The liquid medicine tank is contaminated. When the waste liquid splashes or flows quickly, the inner side wall of the upper cover can block the waste liquid so that it does not flow into the side wall of the upper cover, which can effectively collect the waste liquid and prevent the sewage from overflowing to the outer wall of the main unit. The height setting of the liquid on the inner side wall of the upper cover allows the machine to tilt when blocking the waste liquid. When the tilt angle of the machine does not exceed 30 degrees, the waste liquid collection will not exceed the top end surface of the upper cover and will not flow out to the side wall of the upper cover. The collected waste liquid can flow into the waste liquid tank. It can solve the problem of waste liquid flowing to the outer wall of the main unit due to tilting during use. It uses a more humane setting, so that the device has the effect of preventing liquid medicine from overflowing.

[0020] 3. In this application, an air inlet hole is opened on the upper part of the bottom cover, and a one-way valve is installed in the air inlet hole. The one-way valve can be opened in one direction to connect the gas between the outside world and the air pump when working, and is in a normally closed state when not working. It can isolate the external water mist or water vapor from entering the interior of the machine, and can protect the internal movement control board electronic components and display screen from corrosion, thereby increasing their service life.

[0027] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0028] Reference Figure 1-5 ,

[0029] Example:

[0030] Reference Figure 2-5A waterproof nasal cleaning device with a display and anti-drug spillage prevention function includes a housing 5, a bottom cover 1, a circuit board 14, a battery 4, a lens 7, an air pump 3, a liquid storage tank 8, a pipette 9, an upper cover 10, a drainage cover 11, a nozzle 12, a dust cover 13, and a one-way valve 2. A display screen 15 is provided on the upper surface of the circuit board 14. The display screen 15 and the circuit board 14 are connected via an FPC. The air pump 3 is fixedly connected to the lower surface of the circuit board 14. The battery 4 supplies power to the circuit board 14 and the display screen 15. The air pump 3 is activated and controlled by the MCU, which controls the display screen 15 to display information. The displayed content is presented through the visual window of the lens 7. The lens 7 is fixed to the housing 5 by double-sided tape, glue, ultrasonic connection, etc. The display screen 15 can be set to various functions by pressing buttons, such as working mode, working time, power, number of uses, alarm timing, and other information.

[0031] Reference Figure 2-3 The inner wall of the bottom cover 1 is fixedly connected with a one-way valve 2, and the inner wall of the liquid storage bin 8 is fixedly connected with a venturi tube 18. The outer wall of the venturi tube 18 is sleeved with a liquid suction pipe 9, and there is a reasonably designed gap between the liquid suction pipe 9 and the venturi tube 18. When the air pump 3 is working, the gas enters the one-way valve 2 from the opening of the bottom cover 1, and then opens through the one-way valve 2 to enter the inner cavity of the shell 5. The gas is sucked into the motor through the air inlet of the air pump 3 and then converted and ejected from the air outlet of the air pump 3. When the air pump 3 stops working, no air flow enters the inner cavity of the shell 5, the one-way valve 2 is closed, and the liquid in the shell 5 cannot enter the interior. The one-way valve 2 plays a blocking role, and the gas ejected by the air pump 3 reaches the air inlet of the venturi tube 18. As the air pump 3 continues to work and ejects gas, the gas reaches the arc contraction area of ​​the venturi tube 18, where the air flow The pressure gradually increases and is then ejected through the outlet of the venturi tube 18. When the gas passes through the outlet of the venturi tube 18, the gas flow pressure is high, forming a negative pressure near the outlet of the venturi tube 18. The continuous flow of gas drives the formation of a negative pressure area on the outlet side of the venturi tube 18. Under the action of atmospheric pressure, the liquid in the liquid medicine tank 20 passes through the negative pressure side gap between the suction pipe 9 and the venturi tube 18, first flowing into the negative pressure side gap through the suction port, and then to the outlet side of the venturi tube 18. The gas and liquid are fully mixed at the upper end of the outlet of the venturi tube 18. In this gas-liquid mixing area, the gas continuously and continuously drives the liquid with the negative pressure difference to be atomized into small particles, which are ejected out of the spray outlet under the force of the gas spray. This Venturi effect can make the gas and liquid mix evenly, the spray particle size is uniform, and the spray conversion is efficient and continuous. During the entire atomization process, the liquid medicine does not come into contact with the air pump 3, will not affect the internal structure of the air pump 3, and there is no problem of liquid medicine contamination.

[0032] Reference Figure 1-2The inner wall of the liquid storage bin 8 is provided with a partition plate 17, and the interior of the partition plate 17 is divided into a waste liquid bin 6 and a liquid medicine bin 20 respectively. The upper cover 10 is correspondingly provided with a U-shaped groove 21. When the liquid storage bin 8 and the upper cover 10 are assembled, the upper side wall of the liquid storage bin 8 and the side wall of the partition plate 17 are assembled and matched with the lower side wall of the upper cover 10 and the U-shaped groove 21. The upper cover 10 and the liquid medicine bin 20 are correspondingly provided with an upper cover baffle 16. The clearance between the two parts of the liquid storage bin 8 and the upper cover 10 is designed to be small, and with the upper cover baffle 16, when the whole machine is tilted, it prevents the liquid medicine from overflowing, and the liquid is not easy to flow out, and the liquid medicine will not be wasted due to knocking over the machine. The bottom of the liquid medicine bin 20 is provided with a circular arc surface structure, so that the liquid medicine will always accumulate at the lowest position, which can be maximized during work and reduce the waste of liquid medicine.

[0033] Reference Figure 2-4 , one side of the liquid storage bin 8 is fixedly connected to the other side of the upper cover 10, and a drainage cover 11 is provided on the side of the upper cover 10 away from the liquid storage bin 8. The inner wall of the drainage cover 11 is provided with a drainage groove 22. After the liquid spray is sprayed out and the nasal cavity is cleaned, the waste liquid flows back through two paths. The inner wall of the nozzle 12 flows back to the inner wall of the drainage cover 11, and then flows into the waste liquid bin 6. The waste liquid flows back to the outer wall of the drainage cover 11 through the outer wall of the nozzle 12, and then flows into the drainage slope, flows through the slope to the drainage groove 22, and flows into the waste liquid bin 6. When the outer wall liquid is drained, there is an upper cover baffle on the medicine liquid bin 20, and the waste liquid will flow from the upper cover 10 baffle to the U-shaped groove 21 side, and then flow into the waste liquid bin 6. There is no situation of flowing into the medicine liquid bin 20, which can prevent the waste liquid from flowing back to the medicine liquid bin 20. When the waste liquid is contaminated, the upper cover 10 and the drainage cover 11 are combined to form a waste liquid reflux wall. The upper cover 10 is provided with a liquid blocking side wall of a certain height. When the waste liquid splashes or flows quickly, the upper inner wall of the upper cover 10 can block the waste liquid so that it will not flow into the side wall of the upper cover 10, which can effectively collect the waste liquid and prevent the sewage from overflowing to the outer wall of the main unit. The height setting of the liquid on the upper inner wall of the upper cover 10 allows the machine to tilt when blocking the waste liquid. When the tilt angle of the machine does not exceed 30 degrees, the waste liquid collection will not exceed the top end face of the upper cover 10 and will not flow out to the side wall of the upper cover 10. The collected waste liquid can flow into the waste liquid bin 6, which can solve the problem of waste liquid flowing to the outer wall of the main unit due to tilting during use, and is a more humane setting.

[0034] Reference Figure 2-3 The upper side wall of the liquid storage bin 8 and the lower side wall of the upper cover 10 are sealed together. When the whole machine is tilted, the liquid is not easy to flow out, which prevents the liquid from overflowing and causing waste. This sealing can also prevent waste liquid from flowing into the liquid medicine bin 20, protecting the liquid medicine from being contaminated.

[0035] Reference Figure 2-4An air intake hole is opened on the upper part of the bottom cover 1, and a one-way valve 2 is installed in the air intake hole, which is connected to the air intake port on the air pump 3. Through the one-way air intake effect of the one-way valve 2, the one-way valve 2 is closed when no air is intaked, which solves the problem of preventing liquid from entering the air intake hole and causing corrosion damage to the movement and control motherboard electronic components.

[0036] The implementation principle of an embodiment of a waterproof nasal cleaning device with display and anti-liquid overflow is as follows: power is supplied by battery 4, and power is supplied to circuit board 14 and display screen 15 at the same time. The air pump 3 is started and controlled by MCU, and the display screen 15 is controlled to display information at the same time. The displayed content is presented through the visual window of lens 7. The lens 7 and the shell 5 are fixed by double-sided tape, glue, ultrasonic connection, etc. The display screen 15 can set various functions through buttons, such as working mode, working time, power, number of uses, alarm timing and other information, so that the device has a visual display to significantly enhance user experience and improve information transmission efficiency.

[0037] In addition, after the liquid spray is sprayed and the nasal cavity is cleaned, the waste liquid flows back through two paths. The inner wall of the nozzle 12 flows back to the inner wall of the drainage cover 11, and then flows into the waste liquid bin 6. The waste liquid flows back to the outer wall of the drainage cover 11 through the outer wall of the nozzle 12, and then flows into the drainage slope, flows through the slope to the drainage groove 22, and flows into the waste liquid bin 6. When the outer wall liquid is drained, there is an upper cover baffle on the liquid medicine bin 20, and the waste liquid will flow from the upper cover 1010 baffle to the side of the U-shaped groove 21, and then flow into the waste liquid bin 6. There is no situation of flowing into the liquid medicine bin 20, which can avoid waste liquid Backflow to the liquid medicine bin 20 causes it to be contaminated. When the waste liquid splashes or flows at a fast speed, the upper inner side wall of the upper cover 10 can block the waste liquid so that it does not flow into the side wall of the upper cover 10, which can effectively collect the waste liquid and prevent the sewage from overflowing to the outer wall of the main unit. The height setting of the liquid on the upper inner side wall of the upper cover 10 allows the machine to be tilted when blocking the waste liquid. When the tilt angle of the machine does not exceed 30 degrees, the waste liquid collection will not exceed the top end surface of the upper cover 10 and will not flow out to the side wall of the upper cover 10. The collected waste liquid can be flowed into the waste liquid bin 6. It can solve the problem of waste liquid flowing to the outer wall of the main unit due to tilting during use by the user, and use a more humane setting, so that the device has the effect of preventing liquid medicine from overflowing.
