Description

Technical Field

[0001] This utility model belongs to the field of ozone preparation and water cup technology, and particularly relates to an ozone generating device and a water cup. Background Technology

[0002] Helicobacter pylori (Hp) is a Gram-negative microaerophilic bacterium that colonizes the human gastric mucosa, with a global infection rate exceeding 50%, and even reaching over 80% in some regions. Hp infection is a major cause of chronic gastritis and peptic ulcers, and is also a known risk factor for gastric mucosa-associated lymphoid tissue lymphoma and gastric cancer. The International Agency for Research on Cancer (IARC) of the World Health Organization has classified it as a Group 1 carcinogen.

[0003] Studies have shown that *Helicobacter pylori* (Hp) is not only present in the stomach but may also be found in the oral environment (such as dental plaque and saliva). Oral *Hp* is considered an important source of gastric infection and a potential reservoir for reinfection. Therefore, controlling *Hp* colonization in the oral cavity is of significant public health importance for preventing primary infection, reducing household transmission, and lowering the reinfection rate after eradication therapy.

[0004] Ozone is a strong oxidant with broad-spectrum and highly effective bactericidal and disinfectant capabilities. Its mechanism of action mainly involves oxidizing and destroying the cell membrane, enzyme system, and genetic material of bacteria. Numerous in vitro studies have confirmed that ozone water has a significant inactivation effect on Helicobacter pylori. Upon contact with H. pylori, ozone water can rapidly destroy its cell structure, leading to bacterial death. Drinking a safe concentration of ozone water in moderation may allow the reactive oxygen species produced during decomposition to have a certain inhibitory effect on free H. pylori in the stomach. Gargling with ozone water, utilizing ozone's powerful bactericidal ability, may help inhibit or reduce H. pylori colonization in the oral environment, thereby potentially cutting off an important route of oral transmission of H. pylori.

[0005] However, traditional ozone or ozone water generators are usually bulky, complex to operate, and expensive, failing to meet the needs of individuals for daily, portable, and safe use of ozone water for oral cleaning and drinking. Summary of the Invention

The touch display component 92 covers the opening of the cavity 90 and provides touch and display functions. The touch operation can turn the ozone generator on and off according to the displayed information. The displayed information can be set as needed, such as the ozone generator's on / off state, ozone concentration display or selection, and battery level display or prompt.

[0044] The above description is merely a specific example of this utility model and does not constitute any limitation on this utility model. Obviously, those skilled in the art, after understanding the content and principle of this invention, may make various modifications and changes in form and detail without departing from the principle and structure of this invention. However, these modifications and changes based on the concept of this invention are still within the scope of protection of the claims of this invention. For example, the connection between the upper and lower ends of the sealing tube 3 and the connector interface 220 and the electrode interface 120, respectively, can be either welded or tightly fitted and sealed with a sealing ring. Furthermore, when the sealing tube 3 is made of insulating material, the negative electrode conductive part 22 can be electrically connected to the negative electrode plate 12 through a wire within the space inside the sealing tube 3. For example, the cup lid assembly 9 can also adopt a structure in which the flip cover 98 is opened or locked by a button; or the touch display assembly 92 can be set on the side of the cup lid assembly 9, or the cup lid assembly 9 can not be set with a touch display assembly 92, but instead it can be replaced by a start switch set on the outer surface of its side wall or top, which is used to start or stop the operation of the ozone generator; in addition, except for the negative electrode plate, since the present invention needs to be in direct contact with drinking water, all conductive parts (such as negative conductive part, sealing tube, negative electrode plate, negative conductive stud, positive conductive stud, conductive spring, conductive screw, etc.) are made of stainless steel or titanium.
