Description

Technical Field

[0001] This utility model relates to the field of dental medical equipment technology, specifically a miniature dental chair end timed drainage device. Background Technology

[0002] Dental chairs are indispensable equipment in dental treatment, and their water supply system provides water for various dental instruments. However, during use, water can easily accumulate in the main water supply system of the dental chair. This stagnant water can breed bacteria over time, affecting the quality of the water used in dental treatment and potentially posing a risk to the patient's oral health.

[0003] Currently, the drainage operation of dental chairs mostly relies on manual labor, which is not only time-consuming and laborious, but also easily overlooked, resulting in untimely drainage and failure to effectively ensure the hygiene of the water supply system. To address this, we propose a device that can automatically drain water at set times. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a miniature dental chair end timed drainage device, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a miniature dental chair end timed drainage device, comprising a water storage tank, a wastewater tank fixedly connected to the outside of the water storage tank, a first water inlet pipe fixedly connected to the inside of the water storage tank, a water distributor fixedly connected to one end of the first water inlet pipe, a three-way gun water inlet pipe fixedly connected to the inside of the water distributor, a mouthwash water inlet pipe fixedly connected to the inside of the water distributor, a first drain pipe fixedly connected to one end of the first drain pipe, a transfer box fixedly connected to one end of the transfer box, a second drain pipe fixedly connected to the inside of the transfer box, one end of the second drain pipe extending into the inside of the wastewater tank, and a first solenoid valve provided on the outside of the first drain pipe.

[0006] Preferably, a first booster pump is provided on the outside of the first water supply pipe.

[0007] Preferably, a second booster pump is provided on the outside of the first drain pipe, and a third booster pump is provided on the outside of the second drain pipe.

[0008] Preferably, the water storage tank is fixedly connected to an inlet pipe.

[0009] Preferably, a third electric valve is provided on the outside of both the three-way gun water supply pipe and the mouthwash water supply pipe.

[0010] Preferably, a first drain pipe is fixedly connected inside the wastewater tank, and a fourth electric valve is provided on the outside of the first drain pipe. A second drain pipe is fixedly connected inside the wastewater tank, and a second electric valve is provided on the outside of the second drain pipe.

[0011] Preferably, a control device is provided on the outside of the first solenoid valve, and a timing module and a wireless transmission module are provided inside the control device. The control device is electrically connected to the first pressure pump, the third electric valve, the second pressure pump, the first solenoid valve, and the third pressure pump. Check valves are provided inside the first drain pipe, the second drain pipe, and the first sewage pipe.

[0012] This invention provides a miniature dental chair end timed drainage device, which has the following beneficial effects:

[0013] 1. This miniature dental chair end-of-line timed drainage device, through a control device, can be preset to open the third electric valve during a specific time period. Simultaneously, the second pressure pump and the first solenoid valve will drain the water stored in the three-way nozzle water supply pipe and the mouthwash water supply pipe into the transfer tank through the first drain pipe. Then, the third electric valve will be closed, and the first pressure pump will be activated again to drain the water stored in the water tank into the water distributor through the first water supply pipe, and then into the transfer tank through the first drain pipe. Then, the third pressure pump will be activated to drain the water stored in the transfer tank into the wastewater tank, and then the wastewater will be drained again through the inlet pipe. The system fills the water tank with water while simultaneously opening the third electric valve and closing the first solenoid valve and the second pressure pump. This refills the water supply pipes of the three-way nozzle and the mouthwash pipe, enabling automatic timed drainage of the dental chair's end pipes without manual operation. This saves manpower and time, improves the maintenance efficiency of the dental chair, and allows the system to quickly drain the accumulated water from the main pipes of the dental chair daily, allowing fresh purified water to quickly fill the main pipes. This effectively prevents the problem of water accumulation and bacterial growth, significantly improving the quality of water used in dental treatment and protecting the oral health of patients.
