Description

Technical Field

[0001] The utility model relates to the technical field of oral cleaning, in particular to a handheld oral cleaning device. Background Art

[0002] The oral cavity is the beginning of the digestive tract, connecting to the outside world through the fissure in the front and connecting to the pharynx through the pharyngeal isthmus in the back. The oral cavity contains organs such as the teeth and tongue. The oral cavity's front wall is the lips, the side walls are the cheeks, the roof is the palate, and the floor of the mouth is composed of mucosa and muscles. Oral diseases or tooth extractions often require cleaning and treatment. Dentists often clean blood and debris from patients after tooth extractions or oral treatments, which is why an oral irrigator is needed.

[0003] For example, an oral rinser with patent number CN219271747U can replace the cleaning head for the same user, and the hollow extension rod together with the cleaning head can be removed for different users, which is safer and more hygienic. Such a device has a simple structure and is easy to use. While rotating to clean, it can be assisted by cleaning liquid to improve the cleaning effect.

[0004] However, there are still some problems when using the above-mentioned oral rinsers. For example, the above-mentioned oral rinsers use a straight and long nozzle to spray pressurized clean water, and the mouth cleaning effect is achieved through the sprayed water column. However, the pressure and impact force of the water column sprayed by the existing oral rinsers cannot be accurately adjusted. When the pressure of the water column is too high, it is easy to cause a large scouring force on the fragile oral mucosa and gums, and the gums will become red, swollen, and bleeding. Therefore, the use effect of the existing oral rinsers is not ideal.

[0005] At the same time, the existing oral irrigators use the method of pouring the water flow for rinsing and cleaning into the water storage tank of the irrigator. However, the volume of the water storage tank is relatively limited. When the oral cavity is cleaned, the used water flow needs to be frequently replenished. This also causes the doctor to constantly pay attention to replenishing the water in the water storage tank while performing oral cleaning, which increases the burden and workload of the doctor, delays the patient's oral cleaning process, and reduces the working efficiency of the oral irrigator. Summary of the Invention

[0006] The present invention aims to solve the problems existing in the prior art and provide a handheld oral rinser to achieve better use effect and higher work efficiency.

[0007] The technical solution adopted by the utility model to solve its technical problems is:

[0008] A handheld oral rinser is designed, comprising a water tank, a handheld handle and a cleaning nozzle. The handheld handle is fixedly connected to the lower end of the water tank, a cleaning pipe is fixedly connected to the front of the water tank, and a cleaning nozzle is fixedly connected to the front end of the cleaning pipe. An oral cleaning water pressure adjustable structure is provided on the inner side of the cleaning pipe, a flushing and water replenishing structure is provided on the outer side of the water tank, and a cleaning water flow impurity filtering structure is provided on the inner side of the water tank.

[0009] Further improvement, the oral cleaning water pressure adjustable structure includes a reinforcement layer and an air pump, the reinforcement layer is fixedly sleeved on the inner side of the cleaning tube, and the interior of the reinforcement layer is fixedly connected with multiple pressure regulating rings, and limiting plates are fixedly installed on both sides of the multiple pressure regulating rings, and multiple expansion air bags are fixedly installed inside the multiple limiting plates, the air pump is fixedly installed on the outer wall of the cleaning tube, the inner side of the air pump is connected to the multiple expansion air bags, and a deflation valve is fixedly installed on the outside of the air pump. The inner sides of the multiple expansion air bags are arranged opposite to the inner sides of the pressure regulating rings. When the water pressure is too low to flush out impurities during oral rinsing, the doctor can connect the power supply to start the air pump below, and the air pump can inflate the multiple expansion air bags. The expansion air bags will squeeze and reduce the diameter of the pressure regulating rings inside the multiple pressure regulating rings, and the pressure of the sprayed water flow will become smaller. The water flow pressure for rinsing the oral cavity is controlled by adjusting the inner diameter of the cleaning tube, which is not easy to damage the patient's oral gums.

[0010] To be further improved, the flushing and water-replenishing structure includes a sealing ring and a water inlet hose, the sealing ring is fixedly mounted on the outer wall of the water tank, the inner side of the sealing ring is threadedly connected to a threaded block, the water inlet hose is fixedly connected to the inner side of the threaded block, and the outside of the water inlet hose is fixedly mounted with a water inlet valve.

[0011] To be further improved, the impurity filtering structure of the cleaning water flow includes a filter screen and a baffle, the baffle is fixedly installed on the inner side of the water tank, the top of the water tank is fixedly installed with a limiting groove, the inner side of the limiting groove is movably connected with a leak-proof strip, the lower end of the leak-proof strip is fixedly connected with a filter screen, the lower end of the filter screen is movably connected with a clamping strip, the two clamping strips are fixedly connected to the bottom end of the inner wall of the water tank, and a micro water pump is fixedly installed on the inner side of the baffle.

[0012] Further improvement, one end of the micro water pump is connected to the inner side of the water tank, the other end of the micro water pump is connected to the inner side of the cleaning pipe, and the other end of the water inlet hose is connected to the inner side of the water tank.

[0013] For further improvement, a control button is movably installed on the outer side of the handheld handle, the control button is electrically connected to the micro water pump through a power supply, the control button is electrically connected to the air pump through a power supply, and the inner side of the cleaning nozzle is arranged opposite to the inner sides of multiple pressure regulating rings.

[0014] The beneficial effect of the present invention is that when the water pressure is too low to flush out impurities during oral irrigation, the doctor can connect the power supply to start the air pump below, and the air pump can inflate multiple expansion air bags. The expansion air bags will squeeze the inner sides of multiple pressure regulating rings to reduce the diameter of the pressure regulating rings, and the pressure of the ejected water flow will become smaller. By adjusting the inner diameter of the cleaning tube to control the water flow pressure for rinsing the oral cavity, it is not easy to hurt the patient's oral gums, thereby making the handheld oral rinser more effective.

[0015] When the water level in the water tank drops insufficiently to complete the oral rinse, the doctor can rotate the threaded block with the water inlet hose and screw it into the inside of the sealing ring. The sealing ring is made of rubber material and has good sealing and leak-proof capabilities. The water inlet valve can be opened manually to control the water flow of the water inlet hose. By continuously replenishing the water source inside the water tank, the doctor does not need to go back and forth, which saves the time for oral cleaning and improves the working efficiency of the handheld oral irrigator.

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] Example 1: Refer to the attached Figure 1-6 : A handheld oral rinser includes a water tank 1, a handheld handle 2 and a cleaning nozzle 3. The handheld handle 2 is fixedly connected to the lower end of the water tank 1, a cleaning pipe 5 is fixedly connected to the front of the water tank 1, and the front end of the cleaning pipe 5 is fixedly connected to the cleaning nozzle 3. The inner side of the cleaning pipe 5 is provided with an oral cleaning water pressure adjustable structure 4, the outer side of the water tank 1 is provided with a flushing and water replenishing structure 6, and the inner side of the water tank 1 is provided with a cleaning water flow impurity filtering structure 7.

[0025] The oral cleaning water pressure adjustable structure 4 includes a reinforcement layer 41 and an air pump 46. The reinforcement layer 41 is fixedly sleeved on the inner side of the cleaning tube 5. The reinforcement layer 41 is made of relatively thick stainless steel material. The reinforcement layer 41 can improve the ability of the cleaning tube 5 to resist water scouring. A plurality of pressure regulating rings 42 are fixedly connected to the interior of the reinforcement layer 41. A plurality of pressure regulating rings 42 are fixedly installed on both sides of the plurality of pressure regulating rings 42. The limiting plates 43 are used to limit the direction of the plurality of inflatable air bags 44 to expand and squeeze inward. A plurality of inflatable air bags 44 are fixedly installed inside the plurality of limiting plates 43. The air pump 46 is fixedly installed on the outer wall of the cleaning tube 5. The inner side of the air pump 46 is connected to the plurality of inflatable air bags 44. When the water pressure is too low during the oral cleaning process, impurities When flushing fails, the doctor can connect the power supply to start the air pump 46 below. The air pump 46 can inflate multiple expansion bags 44. The expansion bags 44 will squeeze the inner sides of multiple pressure regulating rings 42 to reduce the diameter of the pressure regulating rings 42. When the diameter of the pressure regulating rings 42 is reduced, the space for water to pass through will become narrower. In this way, when the total amount of water flow remains unchanged, the pressure of the water flow sprayed from the front end will increase. Conversely, when the doctor opens the air release valve 45, the air flow inside the expansion bag 44 will decrease, the pressure regulating ring 42 will lose the thing for expansion and squeezing, and the pressure of the water flow sprayed will decrease. The air release valve 45 is fixedly installed on the outside of the air pump 46. The inner sides of the multiple expansion bags 44 are arranged opposite to the inner side of the pressure regulating ring 42.

[0026] The reinforcement layer 41 is made of a relatively thick stainless steel material, and the reinforcement layer 41 can improve the ability of the cleaning tube 5 to resist water scouring. The limit plate 43 is used to limit the direction of the multiple expansion airbags 44 to expand and squeeze inward. When the water pressure is too low during oral rinsing and impurities cannot be flushed out, the doctor can connect a power supply to start the air pump 46 below. The air pump 46 can inflate the multiple expansion airbags 44. The expansion airbags 44 will squeeze the inner sides of the multiple pressure regulating rings 42 to reduce the diameter of the pressure regulating rings 42. When the diameter of the pressure regulating rings 42 is reduced, the space for water to pass through will become narrower. In this way, while the total amount of water flow remains unchanged, the pressure of the water sprayed from the front end will increase. Conversely, when the doctor opens the air release valve 45, the air flow inside the expansion airbags 44 will decrease, the pressure regulating rings 42 will lose the object for expansion and squeezing, and the pressure of the sprayed water will decrease. By adjusting the inner diameter of the cleaning tube 5 to control the water flow pressure for rinsing the mouth, it is not easy to damage the patient's oral gums, thereby making the handheld oral rinser more effective.

[0027] The flushing and water replenishing structure 6 includes a sealing ring 61 and a water inlet hose 64. The end of the water inlet hose 64 is connected to an external water source and can continuously supply water to the water storage tank 1. The sealing ring 61 is fixedly installed on the outer wall of the water storage tank 1. The inner side of the sealing ring 61 is threadedly connected to a threaded block 62. When the water level inside the water storage tank 1 drops insufficiently to complete the oral flushing work, the doctor can rotate the threaded block 62 with the water inlet hose 64 and screw it into the inner side of the sealing ring 61. The sealing ring 61 is made of rubber material and has good sealing and leak-proof capabilities. The water inlet hose 64 is fixedly connected to the inner side of the threaded block 62. A water inlet valve 63 is fixedly installed on the outside of the water inlet hose 64. The water inlet valve 63 can be opened manually to control the water flow of the water inlet hose 64.

[0028] The end of the water inlet hose 64 is connected to the external water source, so that water can be continuously supplied to the water tank 1. When the water level in the water tank 1 drops and is not enough to complete the oral rinse, the doctor can rotate the threaded block 62 with the water inlet hose 64 and screw it into the inner side of the sealing ring 61. The sealing ring 61 is made of rubber material and has good sealing and leak-proof capabilities. The water inlet valve 63 can be opened manually to control the water flow of the water inlet hose 64. By continuously replenishing the water source to the inside of the water tank 1, the doctor does not need to be busy back and forth, which saves the time for oral cleaning and improves the working efficiency of the handheld oral rinser.

[0029] The cleaning water flow impurity filter structure 7 includes a filter screen 72 and a baffle 75. The baffle 75 is fixedly mounted on the inner side of the water storage tank 1. A limiting groove 73 is fixedly mounted on the top of the water storage tank 1. The inner side of the limiting groove 73 is movably connected to a leak-proof strip 74.

[0031] The rinsing water flow pressure regulating structure of the handheld oral rinser:

[0032] The reinforcement layer 41 is made of relatively thick stainless steel material, and the reinforcement layer 41 can improve the ability of the cleaning tube 5 to resist water scouring. The limit piece 43 is used to limit the direction of the multiple expansion airbags 44 to expand and squeeze inward. When the water pressure is too low and impurities cannot be flushed out during the oral irrigation process, the doctor can connect the power supply to start the air pump 46 below. The air pump 46 can inflate the multiple expansion airbags 44. The expansion airbags 44 will squeeze the inner sides of the multiple pressure regulating rings 42 to reduce the diameter of the pressure regulating rings 42. When the diameter of the pressure regulating rings 42 is reduced, the space for water to pass through will become narrower. In this way, when the total amount of water flow remains unchanged, the pressure of the water flow sprayed from the front end will increase. Conversely, when the doctor opens the air release valve 45, the air flow inside the expansion airbag 44 will decrease, the pressure regulating ring 42 will lose the object of expansion and squeezing, and the pressure of the sprayed water flow will become smaller. By adjusting the inner diameter of the cleaning tube 5, the water flow pressure for rinsing the oral cavity can be controlled, which is not easy to damage the patient's oral gums.
