Description

Technical Field

[0001] The present invention relates to the technical field of dental treatment equipment, and more particularly, to a control device for flushing and disinfecting the water pipeline of a dental chair. Background Art

[0002] During the use of a dental treatment chair, due to the existence of the back suction effect, even if the problems of ensuring the quality of the water source and effective disinfection are solved, the pollution in the treatment room still exists. If not disinfected, it is easy to form cross-infection between patients. At present, relevant national regulations require that the pipeline be flushed for 20s - 30s before and after treating each patient, and for 2min - 3min before the start and after the end of daily diagnosis and treatment, to physically remove the patient substances entering the water and air pipelines.

[0003] The existing structure of dental treatment chairs is single. The pipeline cleaning requires medical staff to step on the foot switch of the dental chair to complete the flushing operation of the water pipeline of the dental chair. With people paying more and more attention to dental care and the large workload in outpatient clinics, the existing cleaning method seriously reduces the work efficiency of medical staff and greatly increases the labor intensity.

[0004] Therefore, there is an urgent need for a control device for flushing and disinfecting the water pipeline of a dental chair to solve the above-mentioned problems. Summary of the Invention

[0024] Embodiment:

[0025] Please refer to Figures 1-3 , this embodiment provides a dental chair waterway pipeline flushing and disinfection control device, which includes a controller 4, an anti-backflow water tank 3 and a disinfection water tank 2. The anti-backflow water tank 3 includes a plurality of anti-backflow tanks 8. The external water pipe 1 is connected to the disinfection water tank 2 and the anti-backflow tank 8 through a three-way pipe 5, and the anti-backflow tank 8 is connected to the dental chair waterway inlet; a vertical chute is arranged in the anti-backflow tank 8, a pressure plate 9 is slidably arranged in the vertical chute, and the pressure plate 9 abuts against the inner wall of the anti-backflow tank 8; an electric telescopic rod 10 is arranged above the pressure plate 9, and the electric telescopic rod 10 is electrically connected to the controller 4; control valves 6 electrically connected to the controller 4 are arranged on both the external water pipe 1 and the disinfection water tank 2.

[0026] For the cleaning of the pipeline 15 of the existing dental treatment chair, medical staff need to step on the foot switch of the dental chair to complete the flushing operation of the water pipeline of the dental chair. The disinfection effect is poor and the work efficiency is low, which greatly increases the labor intensity. In the present invention, through the anti-backflow tank 8, when medical staff use it, the controller 4 receives the water outlet and water stop commands of the dental syringe from the medical staff, and closes or opens the control valve 6 of the external water pipe 1 in advance. The contraction of the electric telescopic rod 10 forms short-time water supply and prevents backflow to the external water pipe 1, so that the water flow from the external water pipe 1 to the anti-backflow water tank 3 is always in a one-way flow state, effectively avoiding the front end. When disinfection is required, by opening the control valve 6 of the disinfection water tank 2, internal one-way disinfection is completed, greatly improving the disinfection effect and work efficiency. Specifically, when the dental syringe needs to be closed, the controller 4 first closes the control valve 6 of the external water pipe 1, and then the electric telescopic rod 10 contracts to make the backflow enter the anti-backflow tank 8; when the dental syringe needs to be opened, the electric telescopic rod 10 extends to make the water flow in the anti-backflow tank 8 pass through the dental syringe and then open the control valve 6 of the external water pipe 1; disinfection is carried out after a single patient completes the treatment.

[0027] In some embodiments of the present invention, a pressure pump is connected to the disinfection water tank 2. The setting of the pressure pump effectively ensures the one-way flow during disinfection and guarantees the disinfection effect.

[0028] In some embodiments of the present invention, at least 2 anti-backflow tanks 8 are provided. Setting at least 2 anti-backflow tanks 8 can further avoid backflow through the cooperation of the two anti-backflow tanks 8, and the applicability is better.

[0029] In some embodiments of the present invention, a cleaning inlet hole 13 and a cleaning outlet hole 14 are provided at both the top and bottom of the anti-backflow tank 8, and the cleaning outlet hole 14 and the cleaning inlet hole 13 of adjacent anti-backflow tanks 8 are connected through a pipeline 15; the disinfection water tank 2 is provided with a secondary pipe 12 connected to the cleaning inlet hole 13 of the uppermost anti-backflow tank 8. When disinfection is carried out, the disinfection water tank 2 can clean the anti-backflow tank 8 through the secondary pipe 12.

[0030] In some embodiments of the present invention, a pressure sensor 11 is provided in the anti-backflow tank 8, and the pressure sensor 11 is electrically connected to the controller 4. The setting of the pressure sensor 11 facilitates the controller 4 to control the movement of the electric telescopic rod 10 to stabilize the water flow pressure.

[0031] In some embodiments of the present invention, it further includes a buffer pipeline 7, and the buffer pipeline 7 is detachably connected between the external water pipe 1 and the three-way pipe 5; the buffer pipeline 7 is arranged in an "S" shape. The detachably connected buffer pipeline 7 can play a further protective role, and replacement can avoid the aggregation of microorganisms.

[0032] In some embodiments of the present invention, a plurality of one-way valves 18 are provided in the middle of the buffer pipeline 7, and the plurality of one-way valves 18 are connected by a connecting pipe 17. The cooperation of the plurality of one-way valves 18 and the connecting pipe 17 enables water to enter through the one-way valves 18 when water enters, and can effectively prevent the external water pipe 1 from being contaminated in case of accidental backwater.

[0033] In summary, the embodiments of the present invention provide a dental chair waterway pipeline flushing and disinfection control device, which includes a controller 4, a backflow prevention water tank 3 and a disinfection water tank 2. The backflow prevention water tank 3 includes a plurality of backflow prevention tanks 8. The external water pipe 1 is connected to the disinfection water tank 2 and the backflow prevention tanks 8 through a three-way pipe 5, and the backflow prevention tanks 8 are connected to the dental chair waterway inlet; a vertical chute is provided in the backflow prevention tank 8, and a pressure plate 9 is slidably arranged in the vertical chute, and the pressure plate 9 abuts against the inner wall of the backflow prevention tank 8; an electric telescopic rod 10 is arranged above the pressure plate 9, and the electric telescopic rod 10 is electrically connected to the controller 4; control valves 6 electrically connected to the controller 4 are provided on both the external water pipe 1 and the disinfection water tank 2. Through the backflow prevention tank 8 of the present invention, when medical staff use it, the controller 4 receives the water outlet and water stop instructions of the dental gun of the medical staff, and the control valve 6 of the external water pipe 1 is closed or opened in advance. The contraction of the electric telescopic rod 10 forms short-term water supply and prevents backflow to the external water pipe 1, so that the water flow from the external water pipe 1 to the backflow prevention water tank 3 is always in a one-way flow state, effectively avoiding the front end. When disinfection is required, by opening the control valve 6 of the disinfection water tank 2, internal one-way disinfection is completed, greatly improving the disinfection effect and work efficiency.
