Description

Technical Field

[0001] This application belongs to the field of oral hygiene technology, specifically relating to a mouthwash cup. Background Technology

[0002] With societal progress, more and more people are paying attention to oral hygiene. Existing technologies already include equipment that applies electrolytic products with disinfection capabilities to the field of oral cleaning. However, because the cathode and anode products react with each other during the electrolysis process, users need to wait a long time before using the product to reach the required sterilization level, which compromises the user experience. Summary of the Invention

[0003] The technical problem to be solved by this application is to provide a mouthwash cup that cleans the oral cavity by means of electrolytic products. By setting a second output terminal for discharging hydrogen, the consumption of anode products is reduced, the output efficiency of the required electrolytic products is improved, and the user's waiting time is reduced.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0005] A mouthwash cup, comprising:

[0006] A cavity with one open end, the cavity forming a water-containing space;

[0007] The electrolysis module includes a water inlet and two independent first and second outputs. The electrolysis space of the electrolysis module is connected to the water storage space through the water inlet and the first output. The second output is connected to the outside of the water storage space to output hydrogen and reduce the consumption of hydrogen for the anode products.

[0008] Furthermore, the electrolysis space is divided into an anode chamber and a cathode chamber by a hydrogen check valve unit. The second output terminal is located in the cathode chamber. The hydrogen generated at the cathode is discharged through the second output terminal under the obstruction of the hydrogen check valve unit.

[0009] Furthermore, the hydrogen check valve unit is configured as a cation exchange membrane, and the water inlet and the first output of the electrolysis module are both located in the anode chamber.

[0010] Furthermore, the anode chamber and cathode chamber are stacked at the bottom of the water-containing space, and the anode chamber is located on the side of the cathode chamber facing the water-containing space.

[0011] Furthermore, the anode chamber is open, and the direction of the opening is the same as the direction of the opening of the cavity. The opening is at least configured as the water inlet of the electrolysis module.

[0012] Furthermore, the anode, cation exchange membrane and cathode are sequentially attached and arranged, and at least one diffusion hole is provided through the anode and cathode respectively.

[0013] Furthermore, the mouthwash cup also includes a power supply module for supplying power to the electrolysis module;

[0014] The electrolysis module is equipped with a humidity-sensitive element. When there is water in the water-containing space, the humidity-sensitive element activates the control circuit of the electrolysis module.

[0015] Furthermore, the mouthwash cup also includes a charging receiver module, which supplies power to the electrolysis module when it is near the wireless charging module.

[0016] Furthermore, the mouthwash cup also includes a cup lid that is detachably connected to the cavity, and the wireless charging module is disposed on the cup lid.

[0017] Furthermore, a pressure sensor is provided at the wireless charging module. When the feedback value of the pressure sensor is greater than the initial weight, the wireless charging module supplies power to the electrolysis module.

[0018] The initial weight is the weight when the water-containing space is empty.

[0019] By adopting the above technical solution, the present invention has the following beneficial effects:

[0020] 1. The mouthwash cup of the present invention is provided with a second output end for discharging hydrogen gas, which reduces the consumption of reducing substances at the cathode for the anode products and generates more required electrolytic products. For scenarios that require the use of anode products to clean the oral cavity, the present invention can reduce the user's waiting time and ensure the user's user experience.

[0021] 2. In this invention, the hydrogen check valve unit is configured as a cation exchange membrane, and the water inlet is located at the anode chamber. Most of the external water entering the electrolysis space reacts into the desired anode products, except for a portion that enters the cathode chamber due to the characteristics of the ion exchange membrane. Therefore, the conversion ratio between the desired electrolytic products and external water is high in this invention. This means that the invention generates more desired electrolytic products with the same water volume, and less of these electrolytic products are consumed by the cathode products. Compared to the output efficiency of the desired electrolytic products in existing technologies, the output efficiency of the desired electrolytic products in this invention is significantly improved. Furthermore, the output electrolytic products have a higher oxidation-reduction potential. Considering the actual rinsing time of the user, compared to the sterilization rate of the mixed-flow output electrolytic products in existing technologies, under the same electrolysis conditions, the sterilization rate of the mouthwash cup in this invention can still be maintained above 90%.

[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0032] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0033] While existing technologies have devices that apply electrolytic products with disinfection capabilities to the field of oral hygiene, the output efficiency of these products is generally low due to the mixed-flow output of the electrolytic products. As the cathode and anode products react with each other, users have to wait a long time to achieve the disinfection standards, and the user experience cannot be guaranteed.

[0034] In view of this, such as Figure 1-5 As shown, the present invention provides a mouthwash cup that reduces user waiting time by improving the output efficiency of electrolytic products with disinfection capabilities, thereby ensuring the user's user experience.

[0035] Specifically, the mouthwash cup of the present invention includes:

[0036] A cavity 1 with one end open, and a water-containing space 11 is formed inside the cavity 1;

[0037] Electrolysis module 2 includes a water inlet 21 and two independent first and second outputs 22. The electrolysis space of electrolysis module 2 is connected to water storage space 11 through water inlet 21 and first output. Water in water storage space 11 enters the electrolysis space through water inlet 21 to participate in electrolysis. Then, the electrolysis products flow back to water storage space 11 through first output. During this process, the concentration of electrolysis products is higher on the side near electrolysis module 2. The electrolysis products here will gradually diffuse to the lower concentration area, so that the water in water storage space 11 becomes water with bactericidal ability. Users can use the bactericidal ability of electrolysis products to clean their mouths during rinsing to ensure oral hygiene.

[0038] Considering that the cathode and anolyte products react with each other, and that the anolyte product can achieve oral cleaning, this invention provides a second output terminal 22 near the cathode 24. The second output terminal 22 is connected to the outside of the water-containing space 11 to output the hydrogen gas generated at the cathode 24 during electrolysis, reducing the consumption of hydrogen gas for the anolyte product. Compared with the prior art, the concentration of electrolytic products near the electrolysis module 2 in this invention is relatively high, and its diffusion rate is correspondingly faster, thereby allowing the water flow in the water-containing space 11 to quickly transform into a bactericidal water flow.

[0039] On the other hand, in order to prevent the liquid electrolysis products from being discharged through the second output terminal 22 and falling onto the table or desktop, forming watermarks and reducing the user experience, the second output terminal 22 is preferably equipped with a gas-liquid separation unit such as a polytetrafluoroethylene membrane. By utilizing the gas-permeable but water-impermeable properties of the polytetrafluoroethylene membrane, hydrogen can still be discharged through the second output terminal 22, while the electrolysis products are trapped in the electrolysis space.

[0040] Considering that a portion of the hydrogen is discharged to the outside of the water-containing space 11 through the second output terminal 22, but some hydrogen still diffuses to the anode 23 side and reacts with the anode products, in one embodiment of the present invention, a hydrogen check valve unit is provided in the electrolysis module 2, and the cathode 24 and anode 23 are respectively arranged on both sides of the hydrogen check valve unit. At this time, the electrolysis space in the electrolysis module 2 is divided into an anode chamber and a cathode chamber by the hydrogen check valve unit. The second output terminal 22 is arranged on one side of the cathode chamber. The hydrogen generated at the cathode 24 cannot diffuse to the anode 23 side due to the obstruction of the hydrogen check valve unit, and is finally discharged through the second output terminal 22.

[0041] The hydrogen check valve unit can be configured as an ultrafiltration membrane. The hydrogen generated in the cathode chamber cannot enter the anode chamber due to the obstruction of the ultrafiltration membrane, and can only be discharged from the second output terminal 22, thereby reducing the unnecessary consumption of anode products.

[0042] However, in the above embodiments, since the ultrafiltration membrane cannot achieve a water-blocking effect, the electrolysis space within the electrolysis module 2 remains a single unit for liquid products. The reducing products generated at the cathode 24 will still diffuse with the water flow to the anode 23, consuming the anode products. Therefore, in another embodiment of the present invention, the hydrogen check valve unit is configured as an anion exchange membrane. The anion exchange membrane only allows anions to pass through, thus preventing the reducing products at the cathode 24 from entering the anode chamber and consuming the anode products. After external water enters the electrolysis space, it participates in electrolysis at the cathode 24, and then anions such as hydroxide ions enter the anode chamber through the anion exchange membrane to continue participating in electrolysis. The specific electrolysis reaction is as follows:

[0043] At the cathode: 2H₂O + 2e⁻ - →H₂↑+2OH - ;

[0044] Anode: 4OH - -4e - →2H₂O + O₂↑;

[0045] Although the water flow starts electrolysis from the cathode 24, water is generated at the anode 3 during the electrolysis process. Therefore, in this embodiment, liquid electrolysis products can still be output to clean the oral cavity.

[0046] Furthermore, to ensure the output efficiency of the electrolysis products and reduce the user's waiting time, in one embodiment of the present invention, the hydrogen check valve unit is configured as a cation exchange membrane 25. The cation exchange membrane 25 is preferably a proton exchange membrane that only allows hydrogen ions to pass through. In this case, the water inlet 21 and the first output end of the electrolysis module 2 are both located at the anode chamber. After external water enters the electrolysis space, it participates in electrolysis at the anode 23. The generated hydrogen ions enter the cathode chamber through the cation exchange membrane 25 to continue participating in electrolysis. The specific electrolysis reaction is as follows:

[0047] At the anode: 4H₂O - 4e - →O2↑+2H2O+4H + ;

[0048] At the cathode: 2H + +2e - →H2↑;

[0049] In this embodiment, most of the external water entering the electrolysis space is output through the first output terminal in the form of anodic products due to the obstruction of the cation exchange membrane 25. Compared with the prior art where the external water entering the electrolysis space in the diversion form still needs to be converted into cathode products that are not necessary for rinsing, the conversion ratio of the required electrolysis products to the amount of water in this embodiment is relatively high.

[0050] In the prior art, the amount of anode products generated is only 50%, and some of these anode products are also consumed by cathode products. In this embodiment, the conversion ratio of anode products can be improved, and since the hydrogen generated at cathode 24 is discharged through the second output terminal 22, the unnecessary consumption of anode products is avoided. Therefore, the output efficiency of electrolytic products in this embodiment is doubly improved compared with the prior art, further reducing the user's waiting time.

[0051] Because the consumption of hydrogen for the anode products is reduced, the electrolytic products output in this embodiment have a higher redox potential. Under the same rinsing time, the mouthwash cup in this embodiment can more thoroughly clean and sterilize the user's mouth, thereby further improving the user experience.

[0052] Considering that the mouthwash stays in the mouth for a short time when rinsing, a sterilization experiment was conducted for 10 seconds. When using the electrolyzed products of mixed flow output in the existing technology to clean the oral cavity, the sterilization rate was only about 57%. However, when using the electrolysis module 2 equipped with a cation exchange membrane 25 in this embodiment, and using the mouthwash cup in this embodiment, the sterilization rate in 10 seconds can be increased to more than 90%, and the sterilization efficiency is significantly improved.

[0053] Due to the limitations of ion exchange membranes, hydrogen ions inevitably carry some water when passing through cation exchange membrane 25. If this water encounters obstruction, it may drip, forming watermarks on the outer periphery of the mouthwash cup near the second output terminal 22, thus reducing the user experience. Therefore, in this embodiment, a gas-liquid separation unit such as a polytetrafluoroethylene membrane is preferably provided at the second output terminal 22. This ensures that the hydrogen gas generated at the cathode 24 can be smoothly discharged through the second output terminal 22, while water droplets are retained within the cathode chamber. As this water accumulates in the cathode chamber, hydrogen ions will still generate hydrogen gas at the cathode 24, which will then be output through the second output terminal 22. This means that the electrolysis reaction can still proceed normally, and the conversion ratio of the required electrolysis products to the incoming water is further improved.

[0054] Although the water inlet 21 is only located in the anode chamber in this embodiment, the characteristics of the cation exchange membrane can prevent the cathode 24 from burning dry. Alternatively, to further prevent the cathode 24 from burning dry, a small amount of water can be pre-stored in the cathode chamber. Due to the presence of this water, the cathode 24 is kept moist, thus preventing dry burning. On the other hand, external water passes through the cation exchange membrane 25, reducing the amount of water in the cathode chamber and further improving the conversion ratio of the required electrolysis products to the amount of water entering the chamber.

[0055] Regarding the position of the electrolysis module 2 in the cavity 1, in one embodiment of the present invention, the electrolysis module 2 may be disposed on the side wall of the cavity 1, in which case the cathode chamber and the anode chamber are stacked, and the anode chamber is disposed on the side of the cathode chamber facing the water-containing space 11.

[0056] For example, considering that the water flow in the mouthwash cup is almost still, in order to enable users to use a higher concentration of electrolyzed products to rinse their mouths and ensure the cleaning and sterilization efficiency of the oral cavity, the electrolysis module 2 can be set at the commonly used water level. The concentration of electrolyzed products is relatively high at this point, and the cleaning efficiency of the oral cavity is correspondingly higher when the user drinks the electrolyzed products to clean the oral cavity.

[0057] However, in this embodiment, as the water level in the mouthwash cup decreases, when the water level drops to a certain height, it cannot submerge the water inlet 21 of the electrolysis module 2, and the electrolysis module 2 cannot continue to receive water, so the remaining water level cannot continue to be converted into the required electrolysis products.

[0058] Alternatively, in another embodiment of the present invention, the anode chamber and the cathode chamber are stacked at the bottom of the water-containing space 11, and the anode chamber is disposed on the side of the cathode chamber facing the water-containing space 11.

[0059] When placed at the bottom of the water-containing space 11, the water inlet 21 of the electrolysis module 2 is submerged in water for a relatively long time, so the water in the cavity 1 can be continuously electrolyzed. As the electrolysis products diffuse from the place with higher concentration to the place with lower concentration, the water in the water-containing space 11 still has the function of sterilization and cleaning.

[0060] As the distance between the cathode 24 and the anode 23 increases, the voltage required by the electrolysis module 2 also increases to drive ion movement. Therefore, to avoid short circuits, the closer the distance between the cathode 24 and the anode 23, the better. Preferably, the anode 23, the cation exchange membrane 25, and the cathode 24 are sequentially attached. In this case, to shorten the ion movement path, at least one diffusion hole 26 is provided at the anode 23 and the cathode 24 respectively. After participating in electrolysis on the surface of the diffusion hole 26 at the anode 23, cations such as hydrogen ions pass through the cation exchange membrane 25 into the cathode chamber and continue to participate in electrolysis at the diffusion hole 26 at the cathode 24. As described above, the ion movement path is significantly shortened, and the oxygen generated at the anode 23 and the hydrogen generated at the cathode 24 can also diffuse outward through the diffusion hole 26 here.

[0061] Furthermore, considering that the water in the water-containing space 11 is almost still, in order to facilitate the water flow into the electrolysis space to participate in electrolysis, the anode chamber in this embodiment is set with an open opening, and the opening direction of the anode chamber is consistent with the opening direction of the cavity 1. The open anode chamber can facilitate the water flow into the electrolysis space to participate in electrolysis during the pouring process. On the other hand, as the oxygen generated at the anode 23 escapes upward, it drives the surrounding water flow into the electrolysis space to participate in electrolysis, thereby improving the electrolysis efficiency and reducing the user's waiting time. At this time, the open opening is both the water inlet 21 and the first output end.

[0062] The mouthwash cup of this invention can be used in brushing scenarios to sterilize the mouth and toothbrush, or in scenarios where brushing is inconvenient, such as office or outdoor settings. In these cases, the electrolytic products of the mouthwash cup can be used to clean the mouth, quickly eliminating bad breath and making work and life more convenient.

[0063] Users can directly control the start and stop of the electrolysis module 2, or the electrolysis module 2 can also start and stop automatically. For example, in one embodiment of the present invention, the electrolysis module 2 is provided with a humidity-sensitive element. The humidity-sensitive element is used to turn on or off the control circuit of the electrolysis module 2 according to the ambient humidity. Specifically, in this embodiment, when there is water in the water-containing space 11, the humidity-sensitive element turns on the control circuit of the electrolysis module 2. When the water in the mouthwash cup is completely poured out, the humidity-sensitive element turns off the control circuit of the electrolysis module 2 to prevent the electrolysis module 2 from burning dry.

[0064] Accordingly, the mouthwash cup needs to be equipped with a power supply module to supply power to the electrolysis module 2, such as a battery, or it can be connected to an external power source via wires.

[0065] When the mouthwash cup of the present invention is applied to scenarios where brushing teeth is inconvenient, such as office settings, the electrolysis module 2 is conveniently connected to an external power source via wires or wireless charging module 4. In this case, the electrolysis module 2 needs to be equipped with a charging receiver module 3.

[0066] When the electrolysis module 2 is directly connected to an external power source via wires, the user can control the start or stop of the electrolysis module 2.

[0067] When the electrolysis module 2 is wirelessly charged, a pressure sensor can be installed on the wireless charging module 4. When there is water in the mouthwash cup, the electrolysis module 2 will be activated to prevent the electrolysis module 2 from burning dry and to avoid the user from manually activating the electrolysis module 2. Specifically, in this embodiment, when the feedback value of the pressure sensor is greater than the initial weight, it is determined that there is water in the water-containing space 11. The wireless charging module 4 supplies power to the electrolysis module 2. The initial weight is the weight of the water-containing space 11 when it is empty, which can be the sum of the weight of the cavity 1 and the electrolysis module 2. If a handle is provided on the outer periphery of the cavity 1, the initial weight should be the sum of the weight of the cavity 1, the electrolysis module 2 and the handle. That is, in this embodiment, the initial weight should be the sum of the weight of the mouthwash cup structure excluding the wireless charging module 4 when the water-containing space 11 is empty.

[0068] Specifically, such as Figure 4 and Figure 5 As shown, in this embodiment, the electrolysis module 2 includes an anode 23, a cation exchange membrane 25 and a cathode 24 stacked together. The bottom of the cathode chamber is provided with a second output terminal 22 that communicates with the outside of the water-containing space 11. A charging receiving module 3 is correspondingly provided on the outside of the cathode chamber. The charging receiving module 3 at this position is closest to the wireless charging module 4, which can fully ensure the charging efficiency.

[0069] To ensure the sealing of the electrolysis space, such as Figure 3As shown, a first sealing ring 5 is provided on the outer periphery of the anode 23 in the anode chamber, and a second sealing ring 6 is provided on the outer periphery of the cathode 24 in the cathode chamber. The first sealing ring 5 and the second sealing ring 6 are respectively attached to both sides of the cation exchange membrane 25.

[0070] The anode 23 is connected to the charging receiver module 3 through an inverted L-shaped first conductive connector 27. Specifically, the first side of the first conductive connector 27 is fitted to the anode 23, and the second side passes through the mounting hole provided on the first sealing ring 5 and is connected to the charging receiver module 3.

[0071] The cathode 24 is connected to the charging receiver module 3 via an inverted L-shaped second conductive connector 28. Specifically, the third side of the second conductive connector 28 is fitted to the cathode 24, and the fourth side passes through the mounting hole provided on the second sealing ring 6 and is connected to the charging receiver module 3.

[0072] Furthermore, to avoid users needing to carry the wireless charging module 4 separately when going out, in this embodiment, the wireless charging module 4 is integrated into the cup lid of the cavity 1. When users need to clean their mouths to eliminate bad breath while out, they can unscrew the cup lid from the cavity 1, fill the water-containing space 11 with water, and place the water-filled cavity 1 on the cup lid. At this time, the feedback value of the pressure sensor is greater than the initial weight, and the wireless charging module 4 at the cup lid activates the electrolysis module 2 set at the bottom of the water-containing space 11. The electrolysis module 2 electrolyzes the water in the water-containing space 11, and the user can clean their mouth through the electrolysis products.

[0073] In summary, this invention configures the hydrogen check valve unit as a cation exchange membrane 25, with the water inlet 21 located at the anode chamber. Most of the external water entering the electrolysis space, except for a portion that enters the cathode chamber due to the characteristics of the ion exchange membrane, reacts into the desired anode products. Therefore, the conversion ratio between the desired electrolysis products and external water is high in this invention. That is, this invention generates more desired electrolysis products with the same inlet water volume, and less of these electrolysis products are consumed by the cathode products. Compared to the output efficiency of the desired electrolysis products in the prior art, the output efficiency of the desired electrolysis products in this invention is significantly improved. With the increase in output efficiency... With the improvement of the electrolysis module 2, the concentration of electrolytic products on the side adjacent to the electrolysis module 2 is correspondingly higher, so it can diffuse more quickly to the area with lower concentration. The water flow in the water-containing space 11 can be transformed into the mouthwash product at a faster speed. Users can quickly clean their mouths with the help of this invention, ensuring a better user experience. On the other hand, the output electrolytic products have a higher oxidation-reduction potential. Combined with the actual rinsing time of the user, compared with the sterilization rate of the electrolytic products output by mixed flow in the prior art, under the same electrolysis conditions, the sterilization rate of the mouthwash cup of this invention can still be maintained at more than 90%, ensuring the cleaning efficiency of the mouth.

[0074] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
