[0001] This invention relates to the field of toothbrush sterilizer technology, and more specifically, to an intelligent toothbrush sterilizer and its cleaning method. Background Technology

[0002] A toothbrush is a brush used to clean teeth. Generally, toothpaste is added to the toothbrush when brushing teeth. Toothbrushes are an essential item in people's daily lives. With the increasing demands of life, the usage of toothbrushes is also increasing. In order to pursue a higher quality and safer life, people sometimes disinfect their toothbrushes.

[0003] However, existing toothbrush sterilizers do not effectively disinfect toothbrushes. They not only consume a lot of users' time, but also fail to effectively kill bacteria on the toothbrush surface, seriously endangering people's health and safety. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an intelligent toothbrush sterilizer with good disinfection effect, simple structure and strong practicality.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent toothbrush sterilizer, comprising a sterilizer body, the sterilizer body comprising a main housing, a sterilization chamber disposed within the main housing, a cleaning device disposed within the main housing and placed on one side of the sterilization chamber, a circulating stirring device disposed within the main housing and placed on the other side of the sterilization chamber, a rotating seat disposed on the sterilization chamber, a through hole disposed on the rotating seat for the toothbrush to pass through, a rotating device for driving the toothbrush to rotate, and a drainage system communicating with the sterilization chamber.

[0006] The present invention is further configured such that: the cleaning device includes a liquid storage tank disposed on one side of the disinfection box, an inlet pump disposed in the main box, an inlet pipe that sequentially enters the output end of the pump and the disinfection box, an inlet solenoid valve disposed on the inlet pipe, and a pressurizing mechanism disposed on one side of the disinfection box for pressurizing the disinfection box, wherein the input end of the inlet pump is placed in the liquid storage tank.

[0007] The invention is further configured such that: the pressurizing mechanism includes a pressurizing pump disposed in the main housing, a first on / off solenoid valve disposed on the output end of the pressurizing pump, and a first controller for controlling the output air pressure of the pressurizing pump and controlling the on / off state of the first on / off solenoid valve, and the output air pressure of the pressurizing pump is between 2KPa and 3KPa.

[0008] The present invention is further configured such that: the circulating stirring device includes a connecting box disposed in the main box and connected to the disinfection box, a pneumatic pump connected to the connecting box, and a second controller for controlling the start and stop of the pneumatic pump, wherein the cross-sectional area of ​​the connecting box is 1 / 2 of the cross-sectional area of ​​the disinfection box.

[0009] The present invention is further configured such that: a partition is provided between the disinfection box and the connecting box, and a channel is provided between the disinfection box and the connecting box, the channel being the space between the partition and the bottom of the box.

[0010] The present invention is further configured such that: the drainage system includes a drain pipe connected to the disinfection box and a second on / off solenoid valve disposed on the drain channel and used to open or close the drain channel.

[0011] The present invention is further configured such that: a heating mechanism is provided in the main chamber and disposed at the bottom of the disinfection chamber, the heating mechanism comprising a plurality of heating groups, each heating group being evenly distributed at the bottom of the disinfection chamber.

[0012] The invention is further configured such that: the heating assembly consists of a heating element, a housing, and a power cord electrically connected to the heating element; the housing includes a cylindrical body, a handle, and a cylindrical plug; the heating element is installed inside the plug; and the power cord extends from the rear of the handle.

[0013] The present invention is further configured such that: the heating mechanism further includes a plug, the inner end of which includes an assembly hole adapted to the cylinder body, the end of the cylinder body is inserted into the assembly hole, and the end of the cylinder body is bonded or interference-fitted to the assembly hole.

[0014] By adopting the above technical solution, the following beneficial effects are achieved: 1. The sterilizer body includes a main box, a sterilization chamber set inside the main box, a cleaning device set inside the main box and placed on one side of the sterilization chamber, a circulating stirring device set inside the main box and placed on the other side of the sterilization chamber, a rotating seat set on the sterilization chamber, a through hole set on the rotating seat for the toothbrush to pass through, and a rotating device for driving the toothbrush to rotate. Through the cleaning device, the circulating stirring device, and the rotating seat, the rotating device performs rotational cleaning, which is highly practical. Furthermore, the circulating stirring device performs stirring cleaning, achieving a good cleaning effect. Finally, the cleaning liquid is discharged through a drainage system connected to the sterilization chamber, resulting in good usage effect.

[0015] 2. By configuring the cleaning device as follows: a liquid storage tank located on one side of the disinfection chamber, an inlet pump located inside the main chamber, an inlet pipe connecting the output end of the pump to the disinfection chamber, an inlet solenoid valve located on the inlet pipe, and a pressurizing mechanism located on one side of the disinfection chamber for pressurizing the disinfection chamber, with the input end of the inlet pump located inside the liquid storage tank, the disinfection chamber is pressurized by the pressurizing mechanism. When the toothbrush rotates, the pressurizing effect of the pressurizing mechanism on the disinfection chamber creates a continuous covering effect on the toothbrush, achieving a good cleaning effect. It is highly practical and has a simple structure.

[0016] 3. By setting the circulating stirring device to include a connecting box located inside the main box and connected to the disinfection box, an air pressure pump connected to the connecting box, and a second controller for controlling the start and stop of the air pressure pump, the air pressure inside the connecting box is pressurized by the air pressure pump and then released.

Furthermore, by setting the connecting box to have a cross-sectional area that is 1 / 2 the cross-sectional area of ​​the disinfection box, the above structure facilitates repeated vacuum treatment of the air pressure inside the connecting box.

[0017] 4. By setting the heating unit as an electric heating core consisting of an electric heating element, a housing, and a power cord electrically connected to the electric heating element, the housing includes a cylinder, a handle, and a cylindrical plug. The electric heating element is installed inside the plug, and the power cord is led out from the rear of the handle, thus creating a heating effect inside the disinfection box, improving the disinfection effect, ensuring strong stability, and having a simple structure.

[0018] A cleaning method applicable to the above-mentioned smart toothbrush sterilizer includes the following steps: S1, preparation stage: insert the toothbrush into the through hole, place the toothbrush in the sterilization chamber, open the liquid inlet solenoid valve, start the liquid inlet pump to inlet liquid, and control the liquid inlet pump volume. When the controlled liquid inlet volume reaches 2 / 3 of the volume of the sterilization chamber, the liquid inlet pump stops inlet liquid.

[0019] S2. The heating group starts heating and controls the heating temperature of the disinfectant between 50℃ and 70℃. When the preset temperature is reached, the heating group stops heating.

[0020] S3. Start the air pump to pressurize the connecting box. At this time, the air pressure in the connecting box is greater than the air pressure in the disinfection box, and the liquid level in the disinfection box rises. Then turn off the air pump, the air pressure in the connecting box returns to normal, and the liquid level in the disinfection box resets. Repeat the control of the air pump to make the disinfectant in the disinfection chamber ripple and continuously disinfect and clean the toothbrush. The cleaning time is between 3 and 5 minutes.

[0021] S4. Stop the air pump and start the pressurizing pump to pressurize the remaining gas space in the disinfection box. At this time, the liquid level in the connected box rises until it reaches the top. If the liquid level in the disinfection box no longer decreases, continue to pressurize the disinfection box. The pressurization level is between 2KPa and 3KPa. Then close the first on / off solenoid valve to maintain the pressure.

[0022] S5. After the pressure is maintained inside the disinfection box, the rotating device drives the toothbrush to rotate, which thoroughly cleans the toothbrush, and the rotation time is between 3 and 5 minutes.

[0023] S6. The rotating device stops driving the toothbrush to rotate and discharges the disinfectant solution;

[0024] S7. Complete the disinfection process.

[0025] By adopting the above technical solution, beneficial effects are achieved. After proper preparation, the heating unit enhances the cleaning effect. The continuous pressurization and release of the air pump creates a continuous turbulence effect. Heating and stirring simultaneously achieve a good stirring and cleaning effect. Furthermore, the pressurization pump pressurizes the disinfection chamber, and the rotating device drives the rotating seat, thus achieving a continuous covering effect on the toothbrush. This avoids the formation of air vortices when the toothbrush rotates, which would affect the cleaning effect. The solution is highly practical and has a simple structure.
