Description

Technical Field

[0001] The utility model relates to the technical field of dental equipment, in particular to a circulating water tank and a dental suction system. Background Art

[0002] During oral treatment, the cooling water sprayed by the turbine handpiece and the patient's saliva accumulate in the mouth, causing the patient to swallow reflex. The patient needs to spit out the cooling water and saliva in the mouth, which interrupts the treatment. At the same time, the water mist produced by the cooling water sprayed by the turbine handpiece permeates the treatment room, causing secondary pollution. Nowadays, most doctors use dental suction machines to remove the cooling water, saliva and water mist.

[0003] At present, the suction pump used in dental suction machines is generally a liquid ring vacuum pump, which requires tap water during operation. During use, the tap water is directly discharged into the sewer, resulting in a waste of water resources. Utility Model Content

[0030] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0031] The following is attached to the instruction manual Figure 1 and attached Figure 2 , the circulating water tank of the first embodiment of the utility model is introduced.

[0032] In one embodiment, if Figure 1 and Figure 2 As shown, the circulating water box includes a box body 10 and a water vapor separation device 11 arranged in the box body 10 , and the box body 10 is provided with a water replenishment port 12 , a water suction port 13 and a circulating water port 14 .

[0033] The water replenishment port 12 is used to replenish water into the box body 10; the water suction port 13 is used to supply water to the liquid ring vacuum pump; and the circulating water port 14 is used to connect to the water outlet of the liquid ring vacuum pump.

[0034] The water vapor separation device 11 is connected to the circulating water port 14, and is used to separate the water vapor flowing out of the liquid ring vacuum pump. The water vapor separation device 11 has a circulating gas outlet 15 and a circulating liquid outlet. The circulating gas outlet 15 is used to lead the gas separated by the water vapor separation device 11 to the outside of the box body 10, and the circulating liquid outlet is used to lead the water separated by the water vapor separation device 11 into the box body 10.

[0035] When in use, water is supplied to the box body 10 through the water replenishment port 12, the water suction port 13 on the box body 10 is connected to the water inlet of the liquid ring vacuum pump, and the circulating water port 14 on the box body 10 is connected to the water outlet of the liquid ring vacuum pump. Then the liquid ring vacuum pump is started, and the water in the box body 10 is supplied to the liquid ring vacuum pump, and the liquid ring vacuum pump drives the suction machine to perform suction operation. In this process, the sucked mixed water vapor and the water flowing out of the liquid ring vacuum pump are sent to the circulating water port 14, and then enter the water vapor separation device 11. The water vapor separation device 11 separates the gas in the mixed water vapor and leads it to the outside of the box body 10 through the circulating gas outlet 15, and the water in the mixed water vapor is led into the box body 10. On the one hand, the recycling of water flowing through the liquid ring vacuum pump is achieved. On the other hand, since the mixed water vapor entering from the circulating water inlet 14 first acts on the water vapor separation device 11 and is buffered, compared with directly acting on the sewer or the box 10, the noise is reduced.

[0036] It should be noted that the water vapor separation device 11 in the utility model is a prior art. It can adopt the water vapor separation device disclosed in the Chinese utility model patent with authorization announcement number CN220212666U, or it can adopt the water vapor separation device disclosed in the Chinese utility model patent with authorization announcement number CN219964228U. Its specific structure will not be introduced in detail.

[0037] In one of the embodiments, a muffler is provided at the circulating air outlet 15 to further reduce noise.

[0038] In one embodiment, in order to fully utilize the water in the box body 10, the water suction port 13 is located below the water replenishment port 12 and the circulating water port 14. Preferably, the water suction port 13 is arranged at a position close to the bottom surface of the box body 10.

[0039] In one embodiment, since the sucked mixed water vapor contains impurities, in order to prevent dirt from accumulating at the bottom of the box 10, a sewage outlet 16 is further provided on the box 10, and a sewage pipe 17 connected to the sewage outlet 16 is provided in the box 10. Dirt is sucked from the sewage outlet 16 at regular intervals.

[0040] Furthermore, in order to improve the sewage discharge effect, the opening of the sewage discharge pipe 17 faces downward, and the sewage discharge pipe 17 extends toward the bottom of the box body 10. In order to further improve the sewage discharge effect, the distance between the opening of the sewage discharge pipe 17 and the bottom of the box body 10 is two centimeters. Of course, in other embodiments, the distance can also be set to one centimeter or three centimeters.

[0041] In one embodiment, in order to kill bacteria in the water tank and avoid odor in the water tank and the surrounding environment, a sterilization element is provided in the box body 10. Preferably, the sterilization element is a deep ultraviolet LED lamp bead. In other embodiments, a high-pressure mercury lamp can also be used as the sterilization element.

[0042] In one of the embodiments, in order to avoid injecting too much water into the box body 10, an overflow port 18 is provided on the box body 10, and a first water level sensor 19 corresponding to the overflow port 18 is provided in the box body 10, wherein the height position of the first water level sensor 19 is slightly lower than the overflow port 18, and the first water level sensor 19 is used to send a first signal when the water level reaches a first set value to open the overflow port 18. After the overflow port 18 is opened, water above the first set value overflows from the overflow port 18, and at the same time, water injection into the box body 10 is stopped.

[0043] In one of the embodiments, in order to avoid the water in the box 10 failing to meet the demand, a second water level sensor 20 corresponding to the water replenishment port 12 is provided in the box 10, and the height position of the second water level sensor 20 is flush with the water replenishment port 12. The second water level sensor 20 is used to send a second signal when the water level reaches a second set value, so as to replenish water into the box 10 in time.

[0044] In one of the embodiments, a third water level sensor 21 corresponding to the sewage outlet 16 is further provided in the box body 10. The height position of the third water level sensor 21 is slightly higher than the sewage outlet 16. The third water level sensor 21 is used to send a third signal when the water level reaches a third set value, so as to stop the sewage discharge operation in time. At this time, it means that the dirt in the water tank has been discharged, avoiding continuous drainage and wasting water resources.

[0045] In one of the embodiments, a fourth water level sensor 22 corresponding to the water suction port 13 is further provided in the box body 10. The height position of the fourth water level sensor 22 is slightly higher than the water suction port 13. The fourth water level sensor 22 is used to send a fourth signal when the water level reaches a fourth set value, so as to stop the operation of the liquid ring vacuum pump in time. At this time, it means that the amount of water in the box body 10 is small and insufficient to supply the liquid ring vacuum pump. Therefore, the liquid ring vacuum pump needs to be stopped to avoid idling of the liquid ring vacuum pump.

[0046] In one of the embodiments, since too high water temperature will affect the working efficiency of the liquid ring vacuum pump, a temperature sensor 23 is also provided in the box body 10. The temperature sensor 23 is used to detect the temperature of the water in the box body 10 so as to change the water in time when the temperature of the water in the box body 10 exceeds the set value.

[0047] The embodiment of the second aspect of the present invention discloses a dental suction system.

[0048] The dental suction system includes a liquid ring vacuum pump and a circulating water tank. The structure of the circulating water tank is the same as the structure of the circulating water tank in any of the above-mentioned first aspect embodiments, and will not be repeated here.

[0049] The liquid ring vacuum pump has an air inlet, a water inlet and a water outlet. The water inlet is connected to the water suction port 13 of the circulating water tank, and the water outlet is connected to the circulating water port 14 of the circulating water tank.

[0050] When in use, water is supplied to the box body 10 through the water replenishment port 12, the water suction port 13 on the box body 10 is connected to the water inlet of the liquid ring vacuum pump, and the circulating water port 14 on the box body 10 is connected to the water outlet of the liquid ring vacuum pump. Then the liquid ring vacuum pump is started, and the water in the box body 10 is supplied to the liquid ring vacuum pump, and the liquid ring vacuum pump drives the suction machine to perform suction operation. In this process, the sucked mixed water vapor and the water flowing out of the liquid ring vacuum pump are sent to the circulating water port 14, and then enter the water vapor separation device 11. The water vapor separation device 11 separates the gas in the mixed water vapor and leads it to the outside of the box body 10 through the circulating gas outlet 15, and the water in the mixed water vapor is led into the box body 10. On the one hand, the recycling of water flowing through the liquid ring vacuum pump is achieved. On the other hand, since the mixed water vapor entering from the circulating water inlet 14 first acts on the water vapor separation device 11 and is buffered, compared with directly acting on the sewer or the box 10, the noise is reduced.

[0051] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
