Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a dental device with a double water supply system. Background Art

[0002] Traditional dental electric motors rely on the water supply of the dental chair. Once the dental chair is removed, they cannot be used normally. Electric motors with their own water supply do not rely on the dental chair, can be carried outside, and work independently, which has become a new trend.

[0003] Existing dental equipment with dual water supply systems, capable of both internal and external water supply, supplies water to electric motors (or dental handpieces). Both the internal and external water systems are supplied by the same pump (typically a peristaltic pump). Switching between internal and external water supply systems requires replacing the tubing, making switching extremely inconvenient and impacting water availability during surgery. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a dental device with a dual water supply system, which has the advantages of independent water supply in the dual water channels and easy switching.

[0005] A dental device with a dual water supply system comprises a shell, an internal water system and an external water system; the internal water system comprises a water tank, a first water pump and a first motor; the water tank is fixed above the shell, and a water outlet is provided at the bottom thereof, and the water outlet is connected to the internal water channel of the dental mobile phone through a pipe; the first water pump is fixed in the shell and driven by the first motor, and the water flowing out of the water outlet is pumped to the internal water channel of the dental mobile phone through the first water pump; the external water system comprises a hanging rod, a hanging bottle, a second water pump and a second motor; the hanging rod is fixed on the side of the shell, and the hanging bottle is hung upside down on the hanging rod, and the hanging bottle is connected to the external water channel of the dental mobile phone through a pipe; the second water pump is fixed in the shell near the side of the hanging rod and driven by the second motor; the water flowing out of the hanging bottle is pumped to the external water channel of the dental mobile phone through the second water pump.

[0006] The dental device with a dual water supply system described in this utility model has an internal water system that stores water in a water tank and pumps it to the internal water channel of the dental handpiece via a first water pump. The external water system, stored in a hanging bottle, is pumped to the external water channel of the dental handpiece via a second water pump. These two independent water supply systems facilitate switching between the internal and external water channels when supplying water to the dental handpiece.

[0007] Furthermore, a filter is provided in the housing, wherein the water inlet of the filter is connected to the water outlet via a pipe, and the water outlet of the filter is connected to the inner water channel of the dental handpiece via a pipe. The filter is used to filter the liquid flowing out of the water tank, so that the liquid transported to the inner water channel of the dental handpiece is free of impurities and cleaner.

[0008] Furthermore, the housing further comprises a heating module, which comprises a heating film and heat transfer conductors attached to both sides of the heating film. A water channel is provided within the heat transfer conductor, the water inlet of the water channel being connected to the water outlet via a pipe, and the water outlet of the water channel being connected to the internal water channel of the dental handpiece via a pipe. The heating module heats the liquid transported by the internal water system, delivering warm water to the internal water channel of the dental handpiece, thereby enhancing the patient experience during surgery.

[0009] Furthermore, the heating module also includes a temperature measuring element for testing the temperature of the liquid in the water channel.

[0010] Furthermore, the first water pump is a diaphragm pump, fixedly mounted within the housing. The water inlet of the diaphragm pump is connected to the water outlet via a pipe, and its water outlet is connected to the internal water channel of the dental handpiece via a pipe. The second water pump is a peristaltic pump, fixedly mounted within the housing. One end of the peristaltic pump's pump tube is connected to the hanging bottle, bypassing the pump body, and the other end is connected to the external water channel of the dental handpiece. The internal water system uses a diaphragm pump to pump water. Compared to a peristaltic pump, its water supply pressure is higher, providing a higher internal water flow rate for the smaller internal water holes of the dental handpiece. It also eliminates the need for consumables such as pump tubes, thus avoiding the risk of pipe bursts.

[0011] Furthermore, it also includes a pump cover, which is arranged on the shell and located above the peristaltic pump; a curved boss is fixedly provided at the lower end of the pump cover. When working, the pump tube of the peristaltic pump is clamped between the curved boss and the pump body of the peristaltic pump, and the water is squeezed and pumped by the roller of the peristaltic pump.

[0012] Furthermore, the curved boss is provided with an inlet pipe channel at one end close to the hanging rod, and an outlet pipe channel at the other end; when working, a section of the pump tube of the peristaltic pump close to the hanging bottle is clamped in the inlet pipe channel, and a section close to the dental mobile phone is clamped in the outlet pipe channel, and the middle section is clamped between the curved boss and the pump body of the peristaltic pump.

[0013] Furthermore, the pump cover is rotatably connected to the shell at one end close to the hanging bottle, and a first elastic member is provided at the rotational connection. The first elastic member applies an upward force to the pump cover, and the pump cover is clamped to the shell at one end away from the hanging bottle.

[0014] Furthermore, it also includes a button, which is arranged on the shell and is clamped with the end of the pump cover away from the hanging bottle. A second elastic member is provided at the bottom end of the button, and the second elastic member applies an upward force to the button; the button and the pump cover are used to facilitate the replacement of the pump tube of the peristaltic pump.

[0015] Furthermore, it also includes a circuit board and an operation display screen. The circuit board is fixed in the shell and electrically connected to the first motor and the second motor. The operation display screen is fixed on the shell and electrically connected to the circuit board for controlling the operation of the first water pump and the second water pump.

[0029] See also Figure 1 The present application provides a dental device with a dual water supply system, including a shell 1, an internal water system 2 and an external water system 3, for supplying water to a dental handpiece 4. The shell 1 is a box on which two different sterile liquids are stored, which are defined as internal water and external water. The internal water system 2 is used to transport the internal water on the shell 1 to the internal water channel of the dental handpiece 4, and the external water system 3 is used to transport the external water on the shell 1 to the external water channel of the dental handpiece 4. When in use, the internal water system 2 or the external water system 3 is selected for connection according to the nature of the dental handpiece 4, and the dual water supply in dental surgery can be achieved by switching the internal water system 2 or the external water system 3 and matching different dental handpieces 4. In this embodiment, the shell 1 is composed of an upper shell and a lower shell that are snapped together.

[0030] The internal water system 2 includes a water storage tank 21 , a filter 22 , a first water pump, a first motor 24 and a heating module 25 .

[0031] The water tank 21 is fixed above the housing 1 and is used to store water. A water outlet is provided at the bottom of the water tank 21. The filter 22 and the first water pump are fixed in the housing 1 and are connected to the water tank 21. Specifically, the water inlet end of the filter 22 is connected to the water outlet through a pipeline. The filter 22 is used to filter the liquid flowing out of the water tank 21, so that the liquid transported to the water channel in the dental handpiece 4 is free of impurities and cleaner. In this embodiment, the first water pump is preferably a diaphragm pump 23. The water inlet end of the diaphragm pump 23 is connected to the water outlet end of the filter 22 through a pipeline. The water outlet end of the diaphragm pump 23 is connected to the water inlet end of the heating module 25 through a pipeline. The diaphragm pump 23 is used to pump the filtered liquid to the heating module 25 for heating. The output shaft of the first motor 24 is connected to the diaphragm pump 23 for driving the diaphragm pump 23 to work. Compared with the traditional internal water system 2 that uses a peristaltic pump 33 to pump water, its water supply pressure is not high, and the internal water channel hole of the dental handpiece 4 is small, which can easily lead to low water output from the internal water channel of the dental handpiece 4, affecting the internal water supply effect of the dental handpiece 4 during use; the internal water system 2 of this application uses a diaphragm pump 23 to pump water, and its water supply pressure is higher, which can provide a larger water flow rate.

[0032] The heating module 25 is used to heat the liquid transported by the internal water system 2 so that it is output to the water channel of the dental handpiece 4 as warm water, which provides a better user experience for the patient during surgery. Furthermore, the heating module 25 is fixed in the housing 1, next to the diaphragm pump 23, and includes a heating film 251 and a heat transfer conductor 252 attached to both sides of the heating film 251; a water channel is provided in the heat transfer conductor 252, and the water inlet end of the water channel is connected to the water outlet end of the diaphragm pump 23 through a pipe, and the water outlet end of the water channel is connected to the inlet end of the internal water channel of the dental handpiece 4 through a pipe. In this embodiment, the heat transfer conductor 252 is metal, preferably a copper alloy. Furthermore, the heating module 25 includes a temperature measuring element for testing the temperature of the liquid in the water channel. In this embodiment, the temperature measuring element is a thermistor.

[0033] The external water system 3 includes a hanging rod 31 , a hanging bottle 32 , a second water pump and a second motor 34 .

[0034] A hanging rod 31 is vertically fixed to one side of the housing 1, with a hook provided at its top. A hanging bottle 32 is hung upside down on the hook, with the bottle mouth facing downward, above the housing 1, for storing saline. A second water pump is fixed within the housing 1. In this embodiment, the second water pump is preferably a peristaltic pump 33. Specifically, the pump body 331 of the peristaltic pump 33 is fixed within the housing 1 near the hanging rod 31. The output shaft of the second motor 34 is fixedly connected to the central axis of the pump body 331 of the peristaltic pump 33, and is used to drive the peristaltic pump 33. The water inlet end of the pump tube 332 of the peristaltic pump 33 is connected to the bottle mouth, bypasses the roller on the pump body 331 of the peristaltic pump 33, and its water outlet end is connected to the external water channel inlet end of the dental handpiece 4 via a pipeline.

[0035] Furthermore, the housing 1 is provided with a pump cover 11, which is located above the pump body 331 of the peristaltic pump 33. A curved boss 111 is fixedly provided at the lower end of the pump cover 11 for contacting the pump tube 332 of the peristaltic pump 33, thereby fitting it against the roller on the pump body 331 of the peristaltic pump 33. The curved boss 111 is provided with an inlet channel 1111 at one end near the hanging rod 31, and an outlet channel 1112 at the other end. During use, the section of the pump tube 332 of the peristaltic pump 33 near the hanging bottle 32 is clamped in the inlet channel 1111, and the section near the dental handpiece 4 is clamped in the outlet channel 1112. The middle section of the pump tube 332 is clamped between the curved boss 111 and the pump body 331 of the peristaltic pump 33, and water is squeezed and pumped by the roller of the peristaltic pump 33.

[0036] Furthermore, the pump cover 11 further includes a button 12, the end of the pump cover 11 near the bottle hanging 32 being rotatably connected to the housing 1, and a first elastic member 112 is provided at the rotational connection, the first elastic member 112 exerting an upward force on the pump cover 11; the button 12 is provided on the housing 1 and is engaged with the end of the pump cover 11 away from the bottle hanging 32, and a second elastic member 121 is provided at the bottom end of the button 12, the second elastic member 121 exerting an upward force on the button 12. Because the pump tube 332 of the peristaltic pump 33 is a consumable, when the pump tube 332 of the peristaltic pump 33 needs to be replaced, the button 12 is pressed downward, the engagement between the button 12 and the pump cover 11 is released, the end of the pump cover 11 near the button 12 bounces upward, and the curved boss 111 is exposed above the housing 1, and the pump tube 332 of the peristaltic pump 33, which is engaged in the inlet channel 1111 and the outlet channel 1112, is removed and replaced. In this embodiment, the first elastic member 112 and the second elastic member 121 are springs.

[0037] Furthermore, the system includes a circuit board 5 and an operation display screen 6. The circuit board 5 is fixedly mounted in the housing 1 and is electrically connected to the first motor 24, the second motor 34, and the heating module 25. The operation display screen 6 is fixedly mounted at the upper end of the housing 1 and is electrically connected to the circuit board 5. It is used to control the operation of the diaphragm pump 23, the peristaltic pump 33, and the heating module 25, thereby controlling the operation and switching of the internal water system 2 and the external water system 3.

[0038] Furthermore, it also includes a switch and a power socket, which are fixed on the housing 1 and electrically connected to the first motor 24 , the second motor 34 , the heating module 25 and the circuit board 5 .

[0039] The dental equipment with a dual water supply system of the present application has an internal water system 2 and an external water system 3, which are two independent water supply systems and can be easily switched between. The internal water system 2 uses a diaphragm pump 23 to pump water. Compared with the peristaltic pump 33, its water supply pressure is higher and it can provide a larger water flow rate. In addition, there are no consumables such as pump tubes, which avoids the risk of pipe bursting. A heating module 25 is also provided in the internal water system 2 to heat the internal water. The external water system 3 uses a peristaltic pump 33 to pump water. The pump tube 332 of the peristaltic pump 33 is easy to replace due to the design of the pump cover 11 and the button 12.

[0040] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous modifications and improvements without departing from the concept of the present invention, and the present invention is intended to encompass such modifications and variations.
