Description

Technical Field

[0001] The utility model relates to the field of water flossers, and in particular to an ozone ion generating device for water flossers. Background Art

[0002] As people pay more and more attention to oral hygiene, oral cleaning and care have also received corresponding attention. Brushing teeth mainly solves the cleaning of the part of the tooth surface that the toothbrush can touch, but it is difficult to solve the cleaning of the gaps between teeth, so other dental cleaning and health care products are also needed for cleaning.

[0003] As a new auxiliary tool for oral cleaning, the water flosser can effectively clean relatively hidden parts such as the gaps between teeth and gingival sulcus. The inventor of the present invention found in actual use that most water flossers on the market can only be used to clean teeth and remove tartar, and have limited health care for teeth. They have little effect on removing bacteria and microorganisms that fill the teeth and oral cavity. The accumulation of microorganisms and bacteria eventually leads to tooth decay, cavities, dental plaque, and various gum diseases. Moreover, the water used for flushing is mostly natural water. If used in a cold state, it may cause gum allergy and inflammation, and even the bacteria contained in the cold water may cause secondary pollution and damage to the teeth. In addition, the trace elements, impurities, inorganic salts and pathogenic bacteria contained in different waters are different. In the process of flushing teeth, it cannot be ruled out that the water is accidentally swallowed into the mouth, which not only fails to protect the purpose of tooth care and oral health, but also brings potential harm to people's physical health.

[0004] Therefore, it is particularly important to optimize the design of the oral irrigator to make it easier, more convenient, safer, more reliable and more comfortable to use. Summary of the invention

[0035] Among them, the shape of the shell 1 is a cylinder with a closed bottom and an open top, and can be made of plastic. A release hole 4 is opened at the lower part of the shell 1. The shape of the release hole 4 is round or square, and the size can be determined according to the capacity of the water tank 7 and the power of the ozone generator 2, to ensure that the liquid in the shell 1 and the water tank 7 can be quickly exchanged. The shell 1 is installed inside the water tank 7, and the bottom of the shell 1 is in the lower middle part of the water tank 7. The ozone generator 2 is installed in the lower part of the accommodating cavity of the shell 1. When the user fills water into the water tank 7, the water contacts the ozone generator 2 from the release hole 4 at the bottom of the shell 1, and the ozone generator 2 reacts with water to generate ozone water and hydrogen-rich water. The piston in the water flosser is connected to the water tank 7 through a water pipe. During the user's use, the ozone water and hydrogen-rich water generated by the ozone generator 2 exchange liquid with the water tank 7 through the release hole 4. The user can control the operation of the piston through the switch on the water flosser to draw the ozone water and hydrogen-rich water in the water tank 7 into the nozzle of the water flosser. Finally, the ozone water and hydrogen-rich water enter the user's mouth through the nozzle for cleaning.

[0036] In this embodiment, the housing 1 and the water tank 7 are connected by snap-fit. Specifically, two bosses extend outward from the top of the housing 1, which are connected to the top wall of the water tank 7 through the bosses, and a second sealing ring 5 is provided at the connection to prevent water in the water tank 7 from entering the water flosser from the connection between the housing 1 and the water tank 7. The water tank 7 is located at the bottom of the water flosser, and the mechanical module and the electronic module of the water flosser are located above the water tank 7. The electronic module includes a power supply component. The opening of the housing 1 connects the electronic module and the ozone generator 2. The ozone generator 2 can be electrically connected to the power supply component in the electronic module to obtain energy to react with water.

[0037] A sealing device is provided in the accommodating cavity of the housing 1 to isolate the water entering the housing 1 from the electronic module and the mechanical module in the water flosser. The sealing device can be located at any position between the opening of the housing 1 and the ozone generator 2.

[0038] like Figure 2 , Figure 3 , Figure 4 As shown, in one embodiment of the utility model, the sealing device includes an intermediate cover 201; the shape of the intermediate cover 201 is adapted to the inner wall of the outer shell 1, and is installed at the lower part of the outer shell 1, and the water entering the outer shell 1 from the release hole 4 is isolated from the opening through the intermediate cover 201.

[0039] Among them, a step is arranged in the accommodating cavity of the outer shell 1, and the step is arranged above the release hole 4 and the ozone generator 2, so that the release hole 4 will not be blocked after the middle cover 201 is installed, and the shape of the middle cover 201 matches the accommodating cavity of the outer shell 1 and the step, so that the outer wall of the middle cover 201 can be in close contact with the accommodating cavity of the outer shell 1, and the middle cover 201 is installed at the lower part of the outer shell 1 through the step to prevent water in the outer shell 1 from entering the water flosser through the opening.

[0040] In this embodiment, the middle cover 201 is made of elastic material, the middle cover 201 and the outer shell 1 are connected by interference fit, and a first sealing ring 205 is provided at the connection between the middle cover 201 and the outer shell 1 to enhance the fixing effect and sealing of the middle cover 201 in the outer shell 1.

[0041] like Figure 2 , Figure 4 As shown, the housing 1 further includes a bottom cover 3 , and a fixing column 204 is disposed on the middle cover 201 , and the bottom cover 3 and the middle cover 201 are connected via the fixing column 204 .

[0042] Among them, a groove that is interlocked with the fixing column 204 is provided on the bottom cover 3. During the installation of the middle cover 201, the fixing column 204 is interlocked with the groove to fix the middle cover 201 to the lower part of the outer shell 1, which can increase the fixing effect of the middle cover 201 and the outer shell 1 and enhance the sealing of the middle cover 201 to the opening of the outer shell 1.

[0043] In this embodiment, the bottom cover 3 and the outer shell 1 can be integrated. By setting a guide strip 6 on the inner wall of the outer shell 1 and setting a guide groove 206 that cooperates with the guide strip 6 on the middle cover 201, the guidance of the guide strip 6 can ensure that the positive electrode sheet 202 and the negative electrode sheet 203 are opposite to the release hole 4 after the middle cover 201 is installed, thereby increasing the liquid exchange between the outer shell 1 and the water tank 7. In addition, by setting a fixing column 204 opposite to the groove of the bottom cover 3, the fixing column 204 can be conveniently installed in the groove using the guide strip 6.

[0044] In addition, in one embodiment of the utility model, the outer shell 1 and the bottom cover 3 can be set as a detachable structure, and the bottom cover 3 is connected to the outer shell 1 by a snap, so that the dirt on the positive electrode sheet 202 and the negative electrode sheet 203 can be cleaned without removing the middle cover 201.

[0045] like Figure 2 As shown, in one embodiment of the utility model, the ozone generator 2 includes a positive electrode sheet 202 and a negative electrode sheet 203; the positive electrode sheet 202 and the negative electrode sheet 203 are fixedly mounted on the middle cover 201, and one end connected to the power supply assembly is located at the upper end of the middle cover 201, and the other end is in contact with the water entering the housing 1 through the release hole 4.

[0046] In this embodiment, the ozone generator 2 is mounted on the middle cover 201, and the middle cover 201 is used to serve as a carrier of the positive electrode sheet 202 and the negative electrode sheet 203, and is also used to seal the opening of the housing 1. Specifically, the positive electrode sheet 202 and the negative electrode sheet 203 are mounted parallel to each other below the middle cover 201, and one end of the positive electrode sheet 202 and the negative electrode sheet 203 connected to the power supply assembly passes through the main body of the middle cover 201 and protrudes above the middle cover 201, and is connected to the opening of the housing 1, and the other end is in contact with the water entering the housing 1. In order to ensure the sealing performance, the middle cover 201 can be injection molded, and the positive electrode sheet 202 and the negative electrode sheet 203 are jointly arranged in the injection mold, so that the sealing performance of the opening of the housing 1 can be ensured, and the fixation of the negative electrode sheet 203 and the positive electrode sheet 202 can be enhanced.

[0047] In this embodiment, the lengths of the positive electrode sheet 202 and the negative electrode sheet 203 are the same, so as to ensure that the currents in the positive electrode sheet 202 and the negative electrode sheet 203 are the same, thereby ensuring the generation and release of ozone.

[0048] In addition, in one embodiment of the present invention, holes are provided on the positive electrode sheet 202 and the negative electrode sheet 203 to increase the contact area between the positive electrode sheet 202 and the negative electrode sheet 203 and the water, increase the dissolution of oxygen, and help ozone to be more evenly dispersed in the water, thereby improving its efficiency and coverage.

[0049] In addition, in one embodiment of the present invention, a sealing device is disposed at the opening of the housing 1 (not shown in the figure), and the positive electrode sheet 202 and the negative electrode sheet 203 are installed at the lower part of the housing 1 through a fixing member.

[0050] In this embodiment, the sealing device can be a cylinder that matches the opening shape of the outer shell 1. A connection hole that is electrically connected to the positive electrode sheet 202 and the negative electrode sheet 203 is opened on the sealing device, and the connection hole is treated with a sealant. The advantage is that there is no need for sealing between the positive electrode sheet 202 and the negative electrode sheet 203 and the fixed component. When the positive electrode sheet 202 and the negative electrode sheet 203 are damaged and replaced, there is no need to consider the sealing problem between the fixed component, which can increase the service life of the ozone ion generating device.

[0051] Figure 5 A water flosser is shown, which applies the ozone ion generating device in one embodiment of the utility model, wherein the water flosser includes a water tank 7; the ozone ion generating device is fixedly installed in the middle of the water tank 7, and the ozone ion generating device transports ozone ions to the water tank 7. The water flosser is provided with a drainage device, which is connected to the water tank 7, and the water in the water tank 7 is output through the drainage device.

[0052] Among them, the shell 1 of the ozone ion generating device is installed in the middle of the water tank 7, and the bottom of the shell 1 is located in the middle and lower part of the water tank 7. When the user fills water into the water tank 7, the water contacts the ozone generator 2 from the release hole 4 at the bottom of the shell 1, and the ozone generator 2 reacts with water to generate ozone water and hydrogen-rich water. The drainage device of the water flosser can be a water pump or a piston, which is connected to the water tank 7 through a water pipe. During the user's use, the ozone water and hydrogen-rich water generated by the ozone ion generating device exchange liquid with the water tank 7 through the release hole 4. The user can control the water pump through the switch on the water flosser to extract the ozone water and hydrogen-rich water in the water tank 7 into the nozzle of the water flosser. Finally, the ozone water and hydrogen-rich water enter the user's mouth through the nozzle for cleaning.

[0053] It is worth mentioning that the ozone ion generating device in the utility model can be used not only in water flossers, but also in electric toothbrushes. By providing a drain outlet connected to a water pump in the brush head of the electric toothbrush, hydrogen-rich water and ozone water can be delivered to the user's oral cavity through the water pump.

[0054] In addition, users can Figure 5 The nozzle in the apparatus can be replaced with a brush head for brushing teeth. The above functions can also be achieved by providing a drainage outlet connected to a water pump on the brush head, which will not be elaborated here.
