[0029] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0030] Example 1

[0031] See Figures 1 to 2 As shown, this utility model discloses a toilet seat sterilization device and a toilet with the toilet sterilization device.

[0032] The toilet seat sterilization device includes a nozzle 1 connected to a sterilization fluid supply mechanism. The nozzle 1 is installed on the toilet seat 2. The nozzle 1 has a spray port 11, which is used to spray the sterilization fluid from the sterilization fluid supply mechanism onto the seat surface 21 of the seat 2 to achieve sterilization of the seat 2.

[0033] The bactericidal fluid can be in gaseous or liquid form, and its generation method is any of the following:

[0034] The sterilization fluid supply mechanism includes an ionization mechanism and a water supply pipe. The ionization mechanism is used to ionize the water from the water supply pipe to form a sterilization medium. The sterilization medium contains at least one or more of ozone, active oxygen, and plasma. The sterilization medium is formed into a gaseous sterilization fluid to achieve sterilization of the seat ring.

[0035] The sterilization fluid supply mechanism includes an ionization mechanism and two water supply pipes. The ionization mechanism is used to ionize water from one of the water supply pipes to form a sterilization medium. The sterilization medium contains at least one or more of ozone, active oxygen, and plasma. The sterilization medium is mixed with water from the other water supply pipe to form a liquid sterilization fluid to achieve the cleaning and sterilization of the seat ring.

[0036] The principle of ionization of water by an ionization mechanism to generate bactericidal media such as ozone, active oxygen, and plasma is existing technology and will not be elaborated here. Those skilled in the art can select the appropriate ionization mechanism according to the type of bactericidal fluid and the required content of bactericidal media.

[0037] Ozone has a bactericidal function and is easily generated through the ionization of water. When needed, it is sprayed from the nozzle onto the bearing surface 21 of the seat ring 2, thereby sterilizing the bearing surface 21 of the seat ring 2, improving the hygiene of the toilet, and eliminating the need for manual operation to wipe the seat ring 2, thus improving the convenience of operation.

[0038] In this embodiment, the nozzle 1 is installed on the seat ring 2. The surface of the seat ring 2 facing away from the bearing surface 21 is defined as the support surface 22. The nozzle 1 is installed on the support surface 22 of the seat ring 2. The spray nozzle 11 passes through the body of the seat ring 2 and extends to its bearing surface 21. The nozzle 1 extends circumferentially along the outer edge of the seat ring 2. The spray nozzles 11 are spaced apart along the extension direction of the nozzle 1.

[0039] The nozzle 1 is formed by a pipe installed on the seat ring 2, which can be a flexible hose or a rigid pipe. In this embodiment, there are two nozzles 1, which are arranged at intervals along the width direction of the seat ring 2, thereby increasing the spray width of the bactericidal fluid and covering most or all of the seat ring bearing surface 21.

[0040] In other embodiments, the nozzle 1 can also be formed by combining a half-pipe and a seat ring 2. The half-pipe is installed on the seat ring 2 and forms a sealed connection with the seat ring 2, so that the space between the half-pipe and the support surface 22 of the seat ring 2 forms the nozzle 1. In this case, the spray port 11 is formed by a through hole penetrating the support surface 22 and the bearing surface 21.

[0041] The injection port 11 is formed by a nozzle mounted on the side wall of the pipe fitting. In order to allow the nozzle to pass through the body of the seat ring 2, the injection port 11 is formed to pass from the support surface 22 of the seat ring 2 to the bearing surface 21. The body of the seat ring 2 is provided with a mounting hole, and the nozzle is mounted in the mounting hole.

[0042] One end of the nozzle 1 is open and the other end is closed. The open end is used to connect to the sterilization fluid supply mechanism so that the sterilization fluid enters the nozzle 1 and is then sprayed out from each spray port 11. The sterilization fluid is sprayed out only when the upper cover 3 and the seat ring 2 are closed. When the sterilization fluid is sprayed out, it falls onto the bearing surface 21 of the seat ring 2 under the obstruction of the upper cover 3, thereby achieving sterilization and disinfection of the seat ring.

[0043] Example 2

[0044] See Figure 3 As shown, the difference between this embodiment and embodiment 1 is that the nozzle 1 in this embodiment is a single nozzle. In order to adapt to the width of the seat ring, the spray nozzle 11 can be changed to a flared nozzle with a gradually increasing inner diameter, thereby expanding the width of the bactericidal fluid when it is sprayed out.

[0045] Example 3

[0046] See Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, the nozzle 1 is installed on the inner side of the upper cover 3, and the spray nozzle 11 faces the bearing surface 21 of the seat ring 2. In this embodiment, there are two nozzles 1, which extend circumferentially along the outer edge of the upper cover 3. The spray nozzles 11 are spaced apart along the extension direction of the nozzles 1, and correspond to the bearing surface 21 of the seat ring 2. The outer edge of the upper cover 3 refers to the area near the edge of the arc-shaped contour of the upper cover 3 body. The edge of the upper cover 3 is close to but slightly larger than the edge of the seat ring 2, so that the upper cover 3 can cover the seat ring 2 when closed. The nozzle 1 extends along the outer edge of the upper cover 3, allowing the spray nozzle 11 to correspond to the bearing surface 21 of the seat ring 2, ultimately spraying the bactericidal fluid onto the bearing surface 21 of the seat ring 2.

[0047] Furthermore, since the diameter of the nozzle 1 and the diameter of the nozzle 11 are much smaller than the width of the bearing surface 21 of the seat ring 2, and the distance between the nozzle 11 and the bearing surface 21 is relatively short after the top cover 3 is closed, the coverage area of ​​the sprayed bactericidal fluid on the bearing surface 21 is limited. Therefore, in this embodiment, the nozzle 11 is set as a trumpet shape with a gradually increasing inner diameter to increase the coverage area of ​​the bactericidal fluid and ensure the bactericidal effect.

[0048] The spray nozzle 11 can also be configured to be inclined from the edge of the top cover 3 toward the center, forming a sterilizing fluid sprayed from the edge to the center. The sterilizing fluid after sterilizing the bearing surface 21 can further diffuse toward the sewage chamber in the center of the toilet (used to receive excrement) to sterilize the sewage chamber and reduce the spread of bacteria carried in the excrement.

[0049] In this embodiment, the nozzle 1 is formed by a pipe installed on the upper cover 3. The pipe can be a flexible hose or a rigid pipe. In other embodiments, the nozzle 1 can also be formed by assembling a half-pipe with the upper cover 3. The half-pipe is installed on the upper cover 3 and forms a sealed connection with the upper cover 3, so that the space between the half-pipe and the inner side of the upper cover 3 forms the nozzle 1.

[0050] Example 4

[0051] See Figure 5 As shown, the difference between this embodiment and embodiment 3 is that the nozzle 1 in this embodiment is a single nozzle.

[0052] Example 5

[0053] See Figure 6 As shown, the difference between this embodiment and embodiment 3 is that the spray pipe 1 extends from the edge of the upper cover 3 to the middle of the upper cover 3. The end of the spray pipe 1 is provided with a nozzle 4, and the spray port 11 is arranged around the peripheral wall of the nozzle 4 and located in the middle of the upper cover 2. The spray port 11 corresponds to the central through hole of the seat ring 2. The central through hole of the seat ring refers to the hole formed by its bearing surface 21 and the surrounding area corresponding to the sewage discharge chamber of the toilet. The spray port 11 corresponds to the central through hole of the seat ring 2, and the bactericidal fluid is sprayed from the spray port 11 to the bearing surface 21 in all directions. The end of the spray pipe 1 located at the edge of the upper cover 3 is used to connect to the bactericidal fluid supply mechanism.

[0054] Along the axial direction of the nozzle 4, the peripheral wall of the nozzle 4 is provided with a double-layer through hole, thereby forming an upper through hole 41 and a lower through hole 42. The upper through hole 41 is closer to the upper cover 3 than the lower through hole 42. The upper through hole 41 forms a spray port 11, and the lower through hole 42 is used to spray bactericidal fluid into the sewage chamber of the toilet, so that the lower through hole 42 can sterilize the sewage chamber and reduce the spread of bacteria carried in the excrement.

[0055] Example 6

[0056] See Figures 7 to 9 As shown, the sterilizing fluid in this embodiment is a sterilizing liquid, which not only sterilizes the bearing surface 21 of the seat ring 2, but also cleans the seat ring 2. A guide groove 23 is provided on the outer edge of the seat ring 2. The guide groove 23 is located below the bearing surface 21 to receive the sterilizing liquid from the bearing surface 21. The seat ring 2 also has a guide hole 24 connecting to the guide groove 23, which guides the liquid from the guide groove 23 to the toilet's drain chamber.

[0057] When the disinfectant fluid is in liquid form, it forms a disinfectant liquid. After being sprayed onto the seat surface 21, the disinfectant liquid flows downwards under gravity, potentially reaching the outer edge of the seat surface 21 and the outer edge of the toilet bowl, or even overflowing onto the floor, causing inconvenience. Therefore, this embodiment provides a guide groove 23 on the outer edge of the seat ring 2. The disinfectant liquid flowing down from the seat surface 21 flows into the guide groove 23 and then through the guide hole 24 to the toilet's drain chamber. This prevents undesirable overflow of the disinfectant fluid (reaching the outer edge of the seat surface 21 and the outer edge of the toilet bowl, or even overflowing onto the floor) from causing inconvenience to the user, and also guides the disinfectant fluid to the drain chamber to dissipate heat.

[0058] In this embodiment, the nozzle 1 is installed on the upper cover 3, and its installation position is roughly the same as that in embodiment 3. For the remaining undescribed parts, refer to embodiments 1 and 3.

[0059] In this embodiment, the nozzle 1 is formed by the enclosing of a half-pipe installed on the upper cover 3 and the inner side of the upper cover 3. More specifically, the half-pipe is provided with grooves at intervals, which creates a gap between the half-pipe and the inner side of the upper cover 3, thereby forming the spray nozzle 11.

[0060] Example 7

[0061] See Figure 10 As shown, the difference between this embodiment and embodiment 6 is that the nozzle 1 in this embodiment is formed by a complete pipe fitting, which is installed and fixed on the inner side of the upper cover 3, and the spray port 11 is formed on the nozzle 4.

[0062] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that the remaining undescribed parts are prior art, and that all changes in form and detail made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims fall within the protection scope of the present invention.
