Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, and in particular to an oral cleaning device. Background Technology

[0002] In clinical practice, it is usually difficult to perform oral cleaning on patients who are intubated, comatose, or critically ill. Therefore, medical staff are required to assist them. The most common method is for medical staff to use tweezers to pick up cotton balls soaked in saline solution and then wipe the patient's mouth. However, this method is inconvenient to operate, requires repeated replacement of cotton balls, and the cotton balls are easy to fall off during the wiping process, making it impossible to clean the patient's mouth simply and quickly.

[0003] In response, existing technologies have been improved. For example, patent document CN 221285970 U discloses an oral care cleaner, which includes a brush head, a connecting tube, and a squeezer. The brush head has several bundles of bristles on one side and has an internal cavity. The inner wall of the cleaning area has water outlets that connect to the cavity. The water outlets are located in the middle of each bundle of bristles to improve the uniformity of water injection and reduce the risk of choking caused by direct water flow. The connecting tube has a channel that communicates with the cavity and a water tank that communicates with the channel. The squeezer is located at the other end of the connecting tube away from the brush head and is connected to the channel. The squeezer has an air outlet pipe that is inserted into the water tank. By pressing the squeezer, the air pressure in the water tank is increased, thereby squeezing water into the brush head to clean the oral cavity.

[0004] However, as can be seen from the attached drawings, when the water tank is inverted 180° during brushing of the upper teeth or upper oral cavity, the water outlet pipe and air outlet pipe will not be inverted accordingly, causing the air from the air outlet pipe to directly enter the water outlet pipe during use, thus interrupting the water supply. Utility Model Content

[0005] This utility model provides an oral irrigator. The technical problem to be solved is that when brushing the upper teeth or the upper part of the oral cavity, the water outlet pipe and the air outlet pipe can move along with the brush to avoid water supply interruption.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] An oral irrigator includes a brush head, a handle, a water reservoir, and a pump. The brush head, water reservoir, and pump are all connected to the handle. One end of the brush head is provided with bristles, and the end of the brush head with bristles also has a water outlet. The pump can pump liquid from the water reservoir through the water outlet on the brush head. The water outlet is connected to the water reservoir via a water outlet pipe. The pump is connected to the water reservoir via a vent pipe. Both the water outlet pipe and the vent pipe are flexible tubes. A solid ball is provided at the suspended end of the water outlet pipe, and a hollow ball is provided at the suspended end of the vent pipe. The hollow ball can be suspended above the liquid, while the solid ball can be submerged in the liquid.

[0008] Compared with the prior art, the present invention achieves at least the following beneficial effects: In the oral irrigator of the present invention, when the water storage bottle is filled with cleaning fluid, the hollow ball is suspended above the liquid surface due to buoyancy, while the solid ball is submerged in the liquid. When the water storage bottle is inverted, the hollow ball still floats on the liquid surface, ensuring that the vent pipe is always connected to the gas in the water storage bottle. The solid ball moves with the liquid, ensuring that the inlet of the water outlet pipe is always submerged in the liquid, thus avoiding water supply interruption. Attached Figure Description

[0016] The present application will now be described in detail with reference to exemplary embodiments shown in the accompanying drawings. However, it should be understood that the present application may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided herein to make the disclosure of the present application more complete and to fully convey the concept of the present application to those skilled in the art.

[0017] In the description of this application, it should be understood that the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limiting the scope of protection of this application.

[0018] To address the drawback of existing oral irrigators where water supply is interrupted when the water tank is inverted while brushing the upper teeth or upper oral cavity, the inventors, after careful analysis, discovered that the main reason for this problem is that the piping connecting to the water tank cannot move with the inverted device, thus preventing the water outlet from being consistently submerged in liquid. Based on this analysis, the inventors have made structural improvements to the oral irrigator.

[0019] like Figure 1-5 As shown, an oral irrigator according to this application includes a brush head 1, a handle 2, a water storage bottle 3, a press pump 4, a water outlet pipe 5, and an air vent pipe 6.

[0020] The brush head 1, water bottle 3, and pump 4 are all connected to the handle 2. One end of the brush head 1 is provided with bristles 11, and the end of the brush head 1 with bristles 11 is also provided with a water outlet 12. The pump 4 can pump the liquid in the water bottle 3 out through the water outlet 12 on the brush head 1. The water outlet 12 is connected to the water bottle 3 through a water outlet pipe 5. The pump 4 is connected to the water bottle 3 through a vent pipe 6. Both the water outlet pipe 5 and the vent pipe 6 are flexible hoses. The water outlet pipe 5 is provided with a solid ball 51 at its suspended end, and the vent pipe 6 is provided with a hollow ball 61 at its suspended end. The hollow ball 61 can be suspended above the liquid, and the solid ball 51 can be immersed in the liquid.

[0021] When the water storage bottle 3 is filled with cleaning fluid, the hollow ball 61 floats above the liquid surface due to buoyancy, while the solid ball 51 is submerged in the liquid. When the water storage bottle 3 is inverted (such as when cleaning the upper teeth), the hollow ball 61 still floats on the liquid surface, ensuring that the vent pipe 6 is always connected to the gas in the water storage bottle 3. The solid ball 51 moves with the liquid, ensuring that the inlet of the water outlet pipe 5 is always submerged in the liquid, thus avoiding water supply interruption.

[0022] The brush head 1 has an annular cleaning area 13 at one end, with bristles 11 evenly distributed on the concave side of the annular cleaning area 13 for cleaning around the teeth. The side of the brush head 1 opposite to the annular cleaning area 13 is a flat cleaning area 14, with raised silicone cleaning blocks 15 evenly distributed on the flat cleaning area 14 for cleaning the tongue or oral mucosa. The combination of the annular cleaning area 13 and the flat cleaning area 14 can adapt to the cleaning needs of different parts of the oral cavity and improve the ease of operation.

[0023] A handle portion 21 is provided below the tail end of the handle 2. A pressing chamber 22 is provided inside the handle portion 21. The pressing pump 4 includes a pressing rod 41, a piston 42, a one-way valve 43, and a spring 44. The pressing rod 41 is sleeved on one end through the piston 42 and is provided in the pressing chamber 22 and is slidably connected to the pressing chamber 22. The other end extends out of the pressing chamber 22 and is provided with a pressing block 411 at the end. A through groove 412 is provided inside the pressing rod 41, which passes through both ends. The one-way valve 43 is provided in the through groove 412. The spring 44 is sleeved on the pressing rod 41 and its two ends abut against the pressing block 411 and the side wall of the handle portion 21, respectively.

[0024] When the pressing block 411 is pressed, the piston 42 compresses the air in the pressing chamber 22, pressurizes the water storage bottle 3 through the vent pipe 6, and the liquid is pumped out through the water outlet pipe 5. After the pressing block 411 is released, the spring 44 returns to its original position, and external air enters the pressing chamber 22 through the one-way valve 43 to achieve continuous pumping.

[0025] The brush head 1 has an adsorption port 16 on one side, and the handle 2 has a negative pressure connector 23 at the tail end. The negative pressure connector 23 is connected to the adsorption port 16 through the adsorption channel 24. The handle 2 also has a negative pressure adjustment hole 25, which is connected to the adsorption channel 24.

[0026] During operation, an external negative pressure device (such as a suction device) can be connected to suction out liquids or residues in the oral cavity through the suction port 16. The handle 2 is also equipped with a negative pressure adjustment hole 25. During operation, medical staff can cover part of the adjustment hole with their thumb to adjust the suction strength and prevent excessive suction from damaging oral tissues.

[0027] The brush head 1 is detachably connected to the handle 2 via a screw sleeve 17. One end of the brush head 1 is provided with a boss 18. The outer end of the boss 18 is provided with a negative pressure connecting post 181 that communicates with the adsorption port 16 and a water injection connecting post 182 that communicates with the water outlet 12. Both the negative pressure connecting post 181 and the water injection connecting post 182 are fitted with sealing rings 183. One end of the handle 2 is provided with a groove that matches the shape of the boss 18, the negative pressure connecting post 181 and the water injection connecting post 182.

[0028] The brush head 1 and handle 2 are detachably connected. For the same patient, the brush head 1 can be replaced each time it is used, while the handle 2 can be reused multiple times before replacement, which can effectively reduce medical costs. During installation, the boss 18 is embedded in the groove of the handle 2, and the sealing ring 183 is sleeved on the connecting post to achieve quick installation and sealing.

[0029] The diameter of the negative pressure connecting column 181 is larger than the diameter of the water injection connecting column 182 to ensure that it will not be installed backwards, thus playing a certain role in preventing mistake-proofing.

[0030] The solid ball 51 and hollow ball 61 at the end of the tubing ensure continuous liquid supply when the water storage bottle 3 is inverted; the dual cleaning zones of ring and plane improve cleaning efficiency; the combination of the press pump 4 and negative pressure suction enables simultaneous cleaning and suction operations; the detachable structure facilitates disinfection and maintenance. This device significantly improves the safety and convenience of oral care, and is especially suitable for the daily care of intubated or critically ill patients.

[0031] It should be understood that all the above embodiments are exemplary and not restrictive. Various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of this utility model should be within the protection scope of this utility model.
