Description

Technical Field

[0001] The utility model relates to a foam liquid adding structure for an intelligent toilet. Background Art

[0002] The foam tank plays a crucial role in smart toilets. Using advanced technology, it skillfully blends cleaning fluid with air, continuously producing a rich, fine foam. This foam not only significantly enhances cleaning effectiveness, ensuring thorough cleaning of every corner of the toilet, but also significantly increases user comfort. As the foam gently releases from the nozzle, it creates a soft, protective shield around the toilet, providing a comprehensive and thoughtful hygiene experience. The foam effectively prevents stains and reduces odors, making the entire user experience more pleasant and secure. Whether in a home or public restroom, the foam tank of a smart toilet silently plays a vital role, bringing greater convenience and comfort to people's lives.

[0003] However, the foam liquid has a certain viscosity and its fluidity is significantly worse than that of water. In the existing liquid adding mechanism, only one liquid adding channel is provided, which makes the flow of the foam liquid extremely slow. It is often necessary to wait for the foam liquid in the liquid adding tank to completely flow down before the liquid adding operation can continue. This situation not only reduces the efficiency of liquid addition, but may also cause inconvenience to the user during use. Especially when frequent liquid addition is required, the long waiting time may make people feel anxious. In order to solve this problem, it is necessary to improve the existing liquid adding mechanism to increase the flow speed and liquid adding efficiency of the foam liquid. Summary of the Invention

[0004] The problem to be solved by the utility model is to provide a foam liquid adding structure for an intelligent toilet. Since the foam liquid has high viscosity and poor fluidity, the foam liquid in the existing adding mechanism flows slowly, and it is necessary to wait until the foam liquid in the adding tank is exhausted before continuing to add liquid. The adding efficiency is low, which brings inconvenience to the user.

[0005] The technical solution adopted by the utility model to solve the above problems is: a foam liquid adding structure of an intelligent toilet, comprising an upper shell and a bottom shell connected in abutment, a foam liquid tank being fixed under the bottom shell, the upper shell being provided with a downwardly concave filling tank, the bottom of the filling tank being provided with a drain pipe and an exhaust pipe, the bottom shell being protruded toward the drain pipe to form a first connecting pipe coaxial with the drain pipe, and a second connecting pipe being protruded toward the exhaust pipe to form a coaxial with the exhaust pipe, when the upper shell and the lower shell are connected in abutment, the lower end of the drain pipe is axially inserted into the inner wall of the first connecting pipe, the lower end of the exhaust pipe is axially inserted into the inner wall of the second connecting pipe, the lower end of the drain pipe is provided with a first annular groove radially concave inwardly, the lower end of the exhaust pipe is provided with a second annular groove radially concave inwardly, sealing members are provided between the first annular groove and the inner wall of the first connecting pipe, and between the second annular groove and the inner wall of the second connecting pipe, the bottoms of the first connecting pipe and the second connecting pipe are both connected to the foam tank through connecting hoses.

[0006] Compared to the existing technology, the addition of an exhaust pipe, an exhaust channel, successfully addresses the problems of poor fluidity caused by the viscosity of the foam liquid and the slow flow caused by the existing liquid filling mechanism having only a single filling channel. Previously, it was often necessary to wait for the foam liquid in the filling tank to drain completely before continuing to fill, which undoubtedly reduced filling efficiency and caused significant inconvenience to the user. The presence of the exhaust pipe allows gas to be discharged smoothly during the filling process, effectively preventing the impact of gas blockage on the flow rate of the foam liquid. This greatly improves filling efficiency and provides users with a more convenient and comfortable user experience. Furthermore, this structure offers significant advantages in terms of simplicity and easy installation, enabling quick installation. Its components are rationally designed, eliminating the need for complex operating procedures and specialized tools, making installation easy for both professional technicians and ordinary users. This convenience not only saves installation time and labor costs, but also greatly facilitates the use and maintenance of the smart toilet, allowing users to enjoy the comfort and convenience of the smart toilet in the shortest possible time.

[0007] Furthermore, the channel of the drainage pipe is a two-section type, wherein the diameter of the upper section is larger than the diameter of the lower section. In this structure, when the foam liquid flows from the filling tank into the drainage pipe, since the diameter of the upper section of the drainage pipe is larger than the diameter of the lower section, when the foam liquid just enters the drainage pipe, the upper section with a larger diameter can provide a more spacious entrance space for the foam liquid, so that the foam liquid can begin to flow into the drainage pipe more smoothly. As the foam liquid flows downward, it enters the lower section with a smaller diameter. This change in diameter can increase the flow rate of the foam liquid to a certain extent, just like the flow rate of water will increase when it passes through a narrow channel. At the same time, this two-section design also helps to regulate and control the flow rate of the foam liquid during the liquid addition process, to avoid the foam liquid flow rate being too fast or too slow, which affects the liquid addition effect.

[0008] Furthermore, the exhaust pipe is a tapered channel that is larger at the top and smaller at the bottom. Since the diameter of the air pipe is small, it is difficult to pull the core during injection molding because the air pipe cavity is too long. Setting the tapered surface reduces the force required for core pulling.

[0009] Furthermore, the sealing member is an O-ring.

[0010] Furthermore, a closing cover is provided at the opening of the liquid filling tank, and the closing cover can reduce the volatilization of the foam liquid. BRIEF DESCRIPTION OF THE DRAWINGS
