Technical Field

[0001] The present invention relates to the technical field of oral cleaning, and in particular to a multifunctional oral cleaning brush head, an oral cleaning device for bedridden patients comprising the brush head, and a use method thereof. Background Art

[0002] Generally, when brushing teeth, people need to hold a toothbrush and a cup of water while standing by the sink. For patients who are bedridden due to illness and have difficulty standing, they will encounter many inconveniences when brushing their teeth. Generally, a caregiver needs to be arranged next to the patient to help the bedridden patient clean the mouth. On the one hand, the caregiver cannot comprehensively clean the bedridden patient's mouth, which may easily lead to the growth of oral bacteria. On the other hand, when the caregiver uses the existing toothbrush products to clean the bedridden patient, equipment such as a negative pressure aspirator or a sputum suction bucket will be used. In addition, another caregiver is required to add clean water to the container for the bedridden patient to use when cleaning the mouth. This not only consumes manpower, but also requires a variety of other equipment to cooperate in oral cleaning. For the equipment, the overall cost is high.

[0003] In addition, existing oral cleaning toothbrushes are unable to clean some hard-to-reach areas in the mouth because the bristles on the brush heads are all fixed structures and the overall size of the bristles is the same. They also lack customization and targeting for users with different oral conditions and cannot meet the oral environments of users of different ages or conditions.

[0004] After searching, a Chinese patent with announcement number CN218682740U discloses a flushing toothbrush, including a toothbrush body, the toothbrush body including a brush handle, a brush head arranged at the end of the brush handle and bristles arranged on the surface of the brush head, the flushing toothbrush also includes an electric suction pump, a suction tube, a water outlet pipe, a water injection pipe, a syringe and a sewage container, the brush handle and the brush head are hollow structures connected to each other, a suction tube joint is provided at the opposite end where the brush handle and the brush head are connected, the suction tube joint is tubular and connected to the hollow part of the brush handle, a water outlet hole and a suction hole are provided on the surface of the brush head provided with bristles, one end of the suction tube is detachably connected to the suction tube joint, and the other end is connected to the water suction port of the electric suction pump, one end of the water outlet pipe is connected to the water outlet of the electric suction pump, and the other end is connected to the sewage container; but since the application does not make improvements on the brush head, the scope of application is narrow, and at the same time, the application requires the assistance of others to inject clean water into the oral cavity through a syringe, which will cause many inconveniences when bedridden patients need to brush their teeth alone.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0023] The inventors have found that patients who are bedridden due to illness and have difficulty standing will encounter many inconveniences when brushing their teeth. Generally, a caregiver needs to be arranged beside the patient to help the bedridden patient clean the mouth, which not only wastes manpower, but also the caregiver cannot comprehensively clean the mouth of the bedridden patient, which can easily lead to the growth of oral bacteria. In addition, the existing oral cleaning toothbrushes cannot clean some hard-to-clean areas in the mouth because the bristles on the brush heads are all fixed structures and the overall size of the bristles is the same. They also lack customization and targeting for users with different oral conditions and cannot meet the oral environment of users at different ages or in different conditions.

[0024] Based on the above findings, the present application proposes a multifunctional oral cleaning brush head and an oral cleaning device for bedridden patients including the brush head. A sliding frame is designed on the brush head, and multiple bristles of different sizes are evenly distributed, and the brush head is controlled by a control device for adjustment. A waste liquid suction component, a spray component and a water cup component are designed. The spray component is controlled by the control device to absorb clean water or mouthwash from the water cup component and spray it in the form of mist into the oral cavity, and the waste liquid is sucked out into the water cup component by the waste liquid suction component. The device has the advantages of simple structure, easy use, wide range of applications and comprehensive cleaning.

The brush head body 1 is also provided with a sliding bristle assembly 102, and the sliding bristle assembly 102 can slide along the circumference of the brush head body 1 to adjust the bristle density of the brush head body 1; The sliding bristle assembly 102 includes a sliding frame 1021, on which are provided a plurality of sliding bristles 1022 that are staggered with the fixed bristles 101. The sliding frame 1021 can slide along a slide rail 1011 formed between two fixed bristles 101, so that the sliding bristles 1022 and the fixed bristles 101 are gathered or dispersed; the cross-sectional diameter and length of each fixed bristle 101 and the sliding bristle 1022 are different. The density of the bristles on the brush head body 1 is adjusted by the sliding frame 1021, so that the brush head body 1 can more flexibly adapt to the cleaning needs of different areas. For example, on the surface of teeth, using denser bristles can better remove dental plaque and food residues, while in the gaps between teeth or in areas that are difficult to reach, sparser bristles can more easily enter the oral gaps for cleaning, thereby achieving a cleaning effect of full coverage and deep cleaning. This targeted cleaning method helps to reduce the occurrence of oral diseases, such as caries and periodontal disease.

The oral cleaning device for bedridden patients according to claim 3, characterized in that: The toothbrush body (2) is provided with a control device (201), and the control device (201) is electrically connected to the toothbrush body (2), the electric telescopic rod (301), the mouthwash pump (505), the clean water pump (506), and the waste liquid pump (507), respectively. The control device (201) can simultaneously drive the clean water pump (506) to deliver clean water and drive the waste liquid pump (507) to suck out waste liquid.

9. The oral cleaning device for bedridden patients according to claim 3, characterized in that: The middle part of the toothbrush body (2) is also provided with a partition plate for separating the control device (201) from the mouthwash pipe (508), the clean water pipe (509) and the waste liquid suction pipe (305).

10. A method for using an oral cleaning device for bedridden patients according to any one of claims 3 to 9, characterized in that: The following steps are involved: S1. Place a water cup assembly (5) filled with clean water and mouthwash on the ground or a horizontal surface on a table, and the bedridden patient holds the toothbrush body (2); S2. The bedridden patient slides the sliding frame (1021) on the brush head body (1), so that the sliding bristles (1022) gather or disperse relative to the fixed bristles (101), and uses the dense bristles to clean dental plaque and food residues in the oral cavity, and uses the sparse bristles to clean the hard-to-reach areas in the oral cavity; S3, using the control device (201) to drive the mouthwash pump (505) in the water cup assembly (5) to extract the mouthwash and spray it out in a mist form through the mouthwash outlet (402) for the bedridden patient to rinse his mouth. After the mouthwash is completed, the control device (201) drives the electric telescopic rod (301) to extend, pushes out the waste liquid suction head (302), and sucks the waste liquid in the oral cavity into the waste liquid chamber (504) through the waste liquid suction head (302); S4. Use the control device (201) to drive the clean water pump (506) in the water cup assembly (5) to pump out the clean water in the clean water chamber (503) and spray it out in a mist form through the clean water outlet hole (401) so that the bedridden patient can rinse his mouth again during surgery. At the same time, drive the waste liquid suction head (302) to synchronously suck the waste liquid in the oral cavity into the waste liquid chamber (504) until the clean water and the waste liquid in the oral cavity are completely pumped out, thereby completing the cleaning of the oral cavity.
