[0043] According to the first aspect of the present invention, a dental chair ozone water system includes an ozone generator 10 and a control switch 20.

[0044] The specific structure of the above-described components of the dental chair ozone water system according to this embodiment will be described below.

[0045] The dental chair includes a treatment section and a seat section, wherein the treatment section includes a side chamber and a floor chamber. In this embodiment, as... Figures 1 to 3 and Figure 6As shown, the ozone generator 10 is installed in the dental chair housing 1, which can be a side box or a floor box. The ozone generator 10 can be an ozone generator capable of producing ozone gas, which is existing technology, and its structure and working principle will not be described in detail here. The ozone generator 10 has an inlet 11 and an outlet 12. The inlet 11 is connected to an external water source, which can be municipal water. The outlet 12 is connected to the dental chair output pipeline. When the ozone generator 10 is not in use, the external water source passes through the ozone generator 10 and directly enters the dental chair output pipeline. When the ozone generator 10 is activated, the external water source passes through the ozone generator 10 and the water dissolves ozone to form ozone water with bactericidal function, thus realizing the bactericidal water entering the dental chair output pipeline and being supplied to the dental chair.

[0046] Specifically, in this embodiment, such as Figure 1 , Figure 2 and Figure 6 As shown, the control switch 20 is communicatively connected to the ozone generator 10 and is used to control the ozone generator 10 to turn on or off. In this way, when the ozone generator 10 is off, the external water source flows sequentially through the inlet 11 and the outlet 12 to the dental chair output pipeline; when the ozone generator 10 is on, the external water source enters the inlet 11 to form ozone water, and the ozone water flows out from the outlet 12 and flows to the dental chair output pipeline. This achieves the purpose of switching between ordinary water and sterilization water as needed, meeting the needs of doctors, and has the advantages of being convenient to use and low in cost.

[0047] The control switch 20 can be a push-button or rotary switch, as long as it can control the start and stop of the ozone generator 10.

[0048] In this embodiment, as Figure 5 As shown, the dental chair ozone water system also includes a flow detection element 90 that is communicatively connected to the ozone generator 10. The flow detection element 90 can be a flow sensor. Along the flow path of the external water source, the flow detection element 90 is located upstream of the liquid inlet 11. The flow detection element 90 and the ozone generator 10 can be connected via a wiring harness. In this way, the flow detection element 90 detects the water flow and feeds it back to the processor 41 as described below. The processor 41 controls the working power of the ozone generator 10 according to the water flow to achieve the output of ozone water of the required concentration.

[0049] In this embodiment, as Figures 1 to 3 , Figure 5 and Figure 6As shown, the dental ozone water system also includes an indicator light 30 that is communicatively connected to the flow detection unit 90. The indicator light 30 can be an LED light, and it can be connected to the processor 41 via a wiring harness. For example, when the flow detection unit 90 detects water flow, the processor 41 outputs a control signal to the indicator light 30, at which point the indicator light 30 lights up green, indicating that it is in working condition. When no water flow is detected, the indicator light 30 turns yellow, indicating that it is in standby condition. It should be noted that the indicator light 30 can convey different information through different colors. In addition, the indicator light 30 can indicate whether water is flowing through the flow detection unit 90 by being on or off, flashing or constantly on, or by different flashing frequencies.

[0050] Preferably, such as Figures 1 to 3 and Figure 6 As shown, the signal light 30 is formed in a ring structure surrounding the control switch 20, which facilitates control and observation by the operator.

[0051] In this embodiment, as Figures 1 to 3 and Figure 5 As shown, the dental chair ozone water system also includes a PCB board 40 (i.e., a printed circuit board for carrying electronic components). The PCB board 40 integrates a control circuit that is communicatively connected to the control switch 20. The control circuit includes the processor 41 as described above. The control circuit is connected to the ozone generator 10 and the flow detection device 90 via wiring harnesses. The opening and closing of the control switch 20 can realize the operation and stop of the control circuit.

[0052] In this embodiment, as Figures 1 to 3 As shown, the dental chair ozone water system also includes a protective shell 50, which is installed in the dental chair housing 1. The PCB board 40 is installed inside the protective shell 50, thus protecting the PCB board 40 from external damage.

[0053] Preferably, the PCB board 40 is first mounted on the fixing plate, and then the fixing plate is installed inside the protective shell 50. This facilitates installation and further ensures the reliability of avoiding damage to the PCB board 40.

[0054] In this embodiment, as Figures 1 to 3 As shown, the dental chair ozone water system also includes a support member 60 installed in the dental chair housing 1. The support member 60 can be a plate-like structure, such as a sheet metal part. The support member 60 is provided with a first mounting position 61 and a second mounting position 62 provided on the side of the first mounting position 61. The protective shell 50 is fixed to the first mounting position 61, and the ozone generator 10 is fixed to the second mounting position 62, thus realizing the fixation and positioning of the protective shell 50 in the dental chair housing 1.

[0055] Specifically, the first mounting position 61 is formed as a planar structure, and the protective shell 50 can be fixed to the first mounting position 61 by fasteners such as screws or bolts; the second mounting position 62 is formed as a through hole structure, and the ozone generator 10 is embedded in the second mounting position 62 and then fixed by fasteners such as screws or bolts, so that the support member 60 fixes the position of the ozone generator 10.

[0056] It should be noted that, Figure 1 and Figure 6 The side boxes with different structures are shown. The dental chair ozone water system of this application can be adapted to dental chairs of different specifications and models. It can be adapted and installed through the support 60 to meet the pipeline connection requirements.

[0057] Due to the operating angle requirements of the ozone generator 10, in this embodiment, such as Figures 1 to 3 and Figure 6 As shown, the height of the liquid outlet 12 on the ozone generator 10 is not lower than the height of the liquid inlet 11 on the ozone generator 10; in a first optional embodiment, the liquid inlet 11 is located below the liquid outlet 12; in a second optional embodiment, the liquid inlet 11 and the liquid outlet 12 are arranged horizontally.

[0058] In this embodiment, as Figure 4 As shown, the dental chair ozone water system also includes a filter assembly connected to the ozone generator 10. Along the path of the external water source, the filter assembly is positioned upstream of the inlet 11. This filters solid impurities in the water before it enters the ozone generator 10, thus ensuring the efficiency of the ozone generator 10. The filter assembly can be installed on the side box of the dental chair or on the floor box of the dental chair.

[0059] Preferably, such as Figure 4 As shown, the filtration assembly includes a first filter element 71 and a second filter element 72 connected in series. The first filter element 71 and the second filter element 72 can be filters. The first filter element 71 is located upstream of the second filter element 72. The pore size of the filter screen in the first filter element 71 is larger than the pore size of the filter screen in the second filter element 72. In this way, the first filter element 71 can filter out solid impurities with larger particle sizes in the water, and the second filter element 72 can further filter out particles with smaller particle sizes. This prevents particles and other impurities from adhering to the working area of ​​the ozone generator 10 and affecting the working efficiency of the ozone generator 10.

[0060] In this embodiment, as Figure 4As shown, the dental chair ozone water system also includes a pressure regulator 80 installed on the water supply pipeline of the external water source to prevent excessive water pressure from damaging components in the pipeline. The pressure regulator 80 can be a pressure regulating valve. The pressure regulator 80 can be installed on the side box of the dental chair or on the floor box of the dental chair. Preferably, along the flow path of the external water source, the pressure regulator 80 is installed between the first filter element 71 and the second filter element 72.

[0061] The ozone water system for dental chairs according to this utility model includes an ozone generator installed in the dental chair housing; the ozone generator has an inlet and an outlet, the inlet being connected to an external water source, and the outlet being connected to the dental chair output pipeline; a control switch is communicatively connected to the ozone generator and is used to control the ozone generator to turn on or off; when the ozone generator is off, the external water source flows sequentially through the inlet and outlet to the dental chair output pipeline; when the ozone generator is on, the external water source enters the inlet to form ozone water, and the ozone water flows out from the outlet and into the dental chair output pipeline, so as to achieve the purpose of switching between ordinary water and sterilization water as needed, meeting the needs of doctors, and having the advantages of convenient use and low cost.

[0062] The dental chair provided by this utility model includes the above-mentioned dental chair ozone water system, and thus has all the beneficial effects of the dental chair ozone water system, which will not be repeated here.

[0063] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them.
