As shown in Figures 1 and 2, this embodiment provides an oral care rinsing toothbrush head, including a brush head body 100, a cleaning channel 200 and a tongue brush 300. By providing a cleaning groove 110 on the brush head body 100, the brush head body 100 is placed in a person's mouth, and the teeth are engaged in the cleaning groove 110. At this time, by starting the flushing water source, the flushing water source will continuously inject cleaning liquid into the inside of the water inlet channel 210, and export the brush head body 100 through the water inlet channel 210, and rinse the human teeth outside the brush head body 100. At the same time, the negative pressure source is started, and the negative pressure generated by the negative pressure source causes the liquid in the oral cavity to be continuously sucked into the water outlet. Channel 220, and suck out of the oral cavity through the water outlet channel 220. During actual use, the oral care rinsing toothbrush head will be installed on the electric handle 500. Of course, it is not ruled out that it is used on an ordinary handle. The electric handle 500 will make the brush head vibrate, and the first bristles 120 on the brush head will directly contact the teeth. During the process of rinsing the teeth, the vibrating first bristles 120 will further clean the entire outer surface of the teeth and the gaps between the teeth, thereby cleaning the oral cavity, avoiding the growth of bacteria in the oral environment, and reducing the occurrence of caries, bad breath, and even VAP, which is the abbreviation of ventilator-associated pneumonia in the medical field.

In the existing technology, oral care is the most common and basic nursing work in clinical nursing work. A good oral environment will not only make oneself feel comfortable, but also shorten the sense of distance with others. Improper oral care will cause a series of discomforts and complications of diseases.

Oral hygiene is particularly important for patients who are bedridden for a long time, are unconscious, and especially those with artificial respiration tubes. A poor oral environment can lead to bacterial growth in the oral environment, causing a series of complications such as caries, bad breath, and even VAP.

At present, the tools for clinical oral care are still cotton balls. Nurses use vascular clamps to clamp cotton balls for oral care. Improper care process will produce adverse consequences such as: 1. The vascular clamps can easily scratch the oral mucosa; 2. The cotton balls can easily be left in the mouth, causing the risk of aspiration; 3. The force is too gentle to achieve a cleaning effect, and it is difficult to clean the teeth deep in the mouth; 4. It is impossible to accurately judge the position of the tongue coating that the patient can accept and clean the tongue coating at that position; 5. In addition, the toothbrush of the existing technology cannot clean the tongue coating while cleaning the teeth.

In order to solve the above technical problems, this embodiment provides an implementation method, specifically: an oral care rinsing toothbrush head, the purpose of which is to clean the teeth and the tongue coating at the same time, to achieve an all-round and deep cleaning effect on the teeth, and the operation is simple, and will not cause serious discomfort or even dangerous consequences to the user.

In this embodiment, a tongue brush 300 is arranged on the brush head body 100, and the brush head body 100 can be connected to an electric handle 500. The electric handle 500 has an electric toothbrush switch 510. When the user or the caregiver controls the opening of the electric toothbrush switch 510, sonic vibrations are generated in the electric handle 500. For details, reference may be made to the prior art: the motor in the electric handle 500 causes high-frequency vibrations, and the driven movement can make the brush head produce high-frequency swings, but the swing amplitude is very small, generally about 5 mm up and down. In other embodiments, the vibration amplitude range can also be expanded according to actual needs. By continuous brushing and cooperating with the water inlet channel 210 of the cleaning channel 200 to inject cleaning liquid, the surface of the teeth and the tongue coating is synchronously rinsed to complete the cleaning of the teeth and the tongue coating, and at the same time, the cleaned cleaning liquid is discharged through the water outlet channel 220 of the cleaning channel 200.

In this embodiment, the cleaning groove 110 adapted to the teeth in the human mouth is arranged on the brush head body 100, which can be understood as: all the teeth of the person are placed in the cleaning groove 110, or most of the teeth of the person can be placed in the cleaning groove 110, so as to achieve the cleaning of all or most of the teeth of the person. This can also be routinely adjusted according to the actual usage needs of the user or patient. The adjustment here means that during the implementation process, the produced brush head can be designed according to the target customer needs to design the shape, size, etc. of the brush head body 100. For example, for users or patients who have difficulty in opening and closing the mouth, it can be implemented to clean the teeth close to the front end of the mouth, reduce the size of the opening of the mouth, and thereby reduce the discomfort or harm to the user or patient during the use of the brush head in this embodiment, so as to meet the usage needs of different user groups, but is not limited to this.

The width of the cleaning groove 110 generally needs to be slightly larger than the thickness of the teeth. On the one hand, it is convenient for the teeth to be placed in and out of the cleaning groove 110. On the other hand, a certain gap space is created for the vibration of the teeth. It can also be used to guide the liquid after cleaning to be discharged, and the first bristles 120 are arranged in the gap space to make full contact with the tooth surface for cleaning. In other embodiments, for users with uneven teeth or tilted teeth, the width of the cleaning groove 110 can also be adjusted to an adaptive size or shape to meet usage requirements, but is not limited to this.

A flushing water source is connected to the water inlet channel 210, and the flushing water source can be an external flusher, a syringe, etc., but is not limited thereto. A negative pressure source is connected to the water outlet channel 220, and the negative pressure source can be a negative pressure suction device for sucking liquid and food residues in the oral cavity, but is not limited thereto. The liquid introduced into the oral cavity through the flushing water source can be water, saline, oral care solution, disinfectant, etc., but is not limited thereto.

In one embodiment, the head of the flushing toothbrush is preferentially connected to an external electric power source, generally a handle with a power source. The electric power source may be a sonic electric motor that controls the high-frequency swing of the brush head to generate vibrations, thereby achieving effective cleaning of the teeth and tongue coating.

In one embodiment, in order to make the brush head body 100 more suitable for the arrangement of teeth in a person's oral cavity, the brush head body 100 can be designed as a U-shaped structure, and then a cleaning groove 110 is provided on the brush head body 100 of the U-shaped structure, so that the cleaning groove 110 is basically the same as the arrangement of teeth in a person's oral cavity, and the teeth can be easily placed in the cleaning groove 110, and the brush head body 100 of the U-shaped structure can also reduce the occupied space in the oral cavity, and increase the convenience of use;

Furthermore, by designing the cleaning groove 110 to include a first brush groove 111 and a second brush groove 112, the first brush groove 111 is used to place the teeth on the maxilla, and the second brush groove 112 is used to place the teeth on the mandible, thereby ensuring that the upper and lower teeth can be cleaned synchronously, and by arranging the first bristles 120 on the inner side surfaces and the bottom surface of the first brush groove 111 and the second brush groove 112, the first bristles 120 can not only clean the two sides of the teeth, but also clean the occlusal surfaces of the teeth, thereby improving the comprehensive cleaning effect of the teeth; on the side of the concave surface formed by the U-shaped structure brush head body 100 relative to the internal direction of the oral cavity, the space formed by the concave surface of the U-shaped structure brush head body 100 is more convenient for installing the tongue coating brush 300, so that the tongue coating brush 300 is located as a whole on the tongue close to the teeth. The specific size of the tongue coating brush 300 can be designed according to the different user conditions, and it is avoided as much as possible to extend into the surface of the user's tongue close to the throat, so as to avoid causing pharyngeal reflex and causing vomiting, suffocation and other problems in the patient.

In one embodiment, by designing the openings of one end of the water inlet channel 210 and the water outlet channel 220 to be inside the first brush groove 111 and the second brush groove 112, it can be further understood that: the opening of the water inlet channel 210 and the opening of the water outlet channel 220 are both located inside the first brush groove 111, and the opening of the water inlet channel 210 and the opening of the water outlet channel 220 are both located inside the second brush groove 112, so that it can fully ensure that the teeth on the maxillary bone and the teeth on the mandible are directly rinsed, and the rinsed liquid can be directly discharged through the water outlet channel 220, avoiding the accumulation of liquid and food residues contaminated after cleaning inside the first brush groove 111, and the liquid and food residues contaminated after cleaning near the bottom of the oral cavity can also be timely discharged through the internal water outlet channel 220 of the second brush groove 112, so that a large amount of liquid and food residues contaminated after cleaning will not continue to accumulate in the oral cavity of the user and the first brush groove 111. On the one hand, it can ensure subsequent continuous and effective cleaning, and on the other hand, it can also avoid a large amount of liquid causing the patient to choke on water, causing serious discomfort, or even suffocation and other serious problems;

Furthermore, by arranging second bristles 310 on the surface of the tongue coating brush 300, the second bristles 310 can directly contact the tongue coating to promote the cleaning of the tongue coating. In addition, the second bristles 310 can also form a gap between the tongue coating brush 300 and the tongue, so that the cleaning liquid in the flushing water source can effectively directly flush the tongue coating, and the cleaning liquid can flow on the surface of the tongue to promote the flow flushing effect of the tongue coating on the surface of the tongue, and if the brush head is connected to an electric power source, the power source will cause the second brush to vibrate, further promoting the cleaning of the tongue coating.

In one embodiment, in order to facilitate the rapid assembly of the brush head body 100 and the tongue coating brush 300, and to ensure that the cleaning liquid can effectively flow into the tongue coating brush 300 through the brush head body 100, and to satisfy the fact that some users are not accustomed to using the tongue coating brush 300, it is necessary to use the brush head body 100 without the tongue coating brush 300. At this time, it is necessary to ensure that a large amount of cleaning liquid will not be lost or depressurized at the position where the brush head body 100 is connected to the tongue coating brush 300, thereby causing waste of cleaning liquid and reducing The brush head body 100 reduces the flushing pressure of the cleaning liquid during teeth cleaning. Therefore, a connecting groove 130 is provided on the brush head body 100. The tongue brush 300 can be directly inserted into the connecting groove 130. The connecting groove 130 has a water inlet interface 230 and a water outlet interface 240. The tongue brush 300 has a water inlet branch channel 320 and a water outlet branch channel 330. When a brush head with a tongue brush 300 is needed, the teeth and tongue coating can be cleaned synchronously. At this time, the tongue brush 300 is inserted into the connecting groove 130. In the connection groove 130, the water inlet branch channel 320 is connected to the water inlet interface 230, and the water outlet branch channel 330 is connected to the water outlet interface 240. Since the water inlet interface 230 and the water outlet interface 240 are respectively connected to the water inlet channel 210 and the water outlet channel 220, the water inlet branch channel 320 can be connected to the water inlet channel 210 and the water outlet branch channel 330 can be connected to the water outlet channel 220. When in use, the cleaning liquid part of the water inlet channel 210 directly rinses the teeth, and the other part will be passed through the water inlet channel 210. The water enters the water inlet branch channel 320 through the water inlet interface 230, and the tongue coating is rinsed through the water inlet branch channel 320. The negative pressure generated by the negative pressure source can draw negative pressure on the water outlet channel 220 to achieve the suction of the cleaned liquid in the oral cavity near the position of the brush head body 100. Since the water outlet branch channel 330 is connected with the water outlet channel 220, the liquid cleaned at the tongue position can be sucked into the water outlet channel 220 through the water outlet branch channel 330, and finally sucked out through the water outlet channel 220.

By arranging a liquid switch 250 inside the water inlet interface 230 and the water outlet interface 240, when the liquid switch 250 is connected between the brush head body 100 and the tongue brush 300, the liquid switch 250 is opened, and when the tongue brush 300 is separated from the brush head body 100, the liquid switch 250 will automatically close, thereby avoiding the problem of the user exporting a large amount of cleaning liquid through the water inlet interface 230 when using the brush head body 100 without the tongue brush 300 installed. Of course, in this state, the open water outlet interface 240 will also affect the negative pressure export of the cleaned liquid through the water outlet channel 220, because the opening of the water outlet interface 240 is generally relatively large, which will affect the pressure difference between the inside and outside of the water outlet channel 220.

The liquid switch 250 can be: a switch with a valve 260. When the valve 260 is pressed, it will deform to open the metal interface and the water outlet interface 240. When the valve 260 stops being squeezed, the multiple valves 260 automatically resume closing to achieve automatic closing.

It can also be: a liquid valve, an automatic valve that can be automatically controlled to open and close, or a manual valve that can be manually controlled to open and close, such as by twisting or pressing, etc.;

Other non-standard parts may also be selected, as long as they can meet the control opening and closing functions of the water inlet interface 230 and the water outlet interface 240, but are not limited to this.

In one embodiment, the liquid switch 250 is preferably a valve 260. By arranging the valve 260 inside the water inlet interface 230 and the water outlet interface 240, the valve 260 can be understood as a structure similar to a heart valve 260 or a vascular valve 260. The valve 260 is made of elastic material, such as rubber. The valve 260 can be one or more. When the tongue brush 300 is installed on the brush head body 100, the tongue brush 300 will squeeze the corresponding valve 260, or it can be understood that the water inlet branch channel 320 and the water outlet branch channel 330 on the tongue brush 300 will press the corresponding valve 260, so that the valve 260 is deformed, and then the water inlet interface 230 and the water outlet interface 240 are opened, and when the water inlet branch channel 320 and the water outlet branch channel 330 on the tongue brush 300 are opened, When 30 stops pressing the corresponding valve 260, the valve 260 will automatically rebound, and a single valve 260 or multiple valves 260 will automatically block the water inlet channel 210 and the water outlet channel 220. During the implementation process, the valve 260 structure has a lower cost. However, when using a brush head without a tongue brush 300, the valve 260 will be squeezed by the cleaning liquid and a small amount of cleaning liquid will seep out, but it will not affect the cleaning effect on the teeth inside the oral cavity. Of course, in other embodiments, the valve 260 can also be improved, and multiple valves 260 can be used together to form a liquid switch 250, and the valve 260 structure is arc-shaped, similar to the heart valve 260, so that the valve 260 has a unidirectional conduction effect to reduce the seepage of the cleaning liquid, but it is not limited to this.

In one embodiment, the tongue coating brush 300 is designed as a telescopic structure, for example, the tongue coating brush 300 has a corrugated structure for achieving telescopic movement, or the tongue coating brush 300 may also be embedded and telescopic.

The specific embeddable retractable tongue brush 300 includes a connecting section 340, a middle section 350 and a distal section 360, which are slidably connected in sequence and are generally located on the same plane as a whole, so that the tongue brush 300 has a stable retractable direction. The specific embeddable retractable interface is not limited, as long as it can achieve retraction, does not affect the cleaning effect, and does not cause discomfort to the user, it can be adopted, such as: by providing sliding grooves on the connecting section 340 and the middle section 350, so that the middle section 350 is inserted into the sliding groove on the connecting section 340, and the distal section 360 is inserted into the corresponding sliding groove of the middle section 350, so that the tongue brush 300 can be retracted as a whole. In order to ensure the cleaning effect of the tongue brush 300 fitting the surface of the tongue, in other embodiments, An elastic sleeve with bristles can be put on the tongue brush 300. The elastic sleeve has multiple holes and is connected to the water inlet branch channel 320 and the water outlet branch channel 330 for flushing and reverse suction of cleaning liquid. In other embodiments, bristles can be directly provided on the connecting section 340, the middle section 350 and the distal section 360. Of course, in this case, there needs to be a certain distance between the connecting position of the connecting section 340 and the middle section 350 without bristles, or an avoidance space is set between the connecting section 340 and the middle section 350. When the connecting section 340 and the middle section 350 slide, some bristles can be moved to the avoidance space to avoid affecting the normal sliding of the connecting section 340 and the middle section 350. Similarly, the middle section 350 and the distal section 360 can also adopt the above method. It is repeated here, but it is not limited to this.

In one embodiment, when a user or patient is partially missing teeth, if the brush head body 100 is used directly to clean the entire teeth, on the one hand, it is easy to damage the gums at the missing tooth position, and on the other hand, it is easy to aggravate the looseness of the surrounding teeth at the missing tooth position. Therefore, a mouth tray 400 is provided on the brush head body 100, and the mouth tray 400 can slide inside the cleaning groove 110. Of course, the mouth tray 400 can also be taken out from the cleaning groove 110. For users with complete oral teeth, the mouth tray 400 will be taken out from the cleaning groove. When used for users with partially missing teeth, the mouth tray 400 can be moved to the cleaning groove. The dental tray 400 is installed inside the toothbrush, and then the dental tray 400 is slid to move the dental tray 400 to the position corresponding to the missing teeth, and then the brush head is introduced into the user's oral cavity, and the normal teeth will bite into the cleaning groove 110, and the place without teeth will be filled with the dental tray 400, and then the teeth are cleaned by the brush head. At this time, the dental tray 400 protects the gums at this position, and the gums can be prevented from being directly rinsed by the cleaning liquid with a certain flushing force, thereby protecting the gums. In the process of cleaning normal teeth, the dental tray 400 can also play a supporting effect on the surrounding teeth, reducing the problem of loosening of the surrounding teeth due to long-term cleaning;

Furthermore, by providing a third bristle 410 on a side of the mouth tray 400 opposite to the connected teeth, the third bristles 410 can also clean the sides of the surrounding teeth, ensuring an all-round cleaning effect on the teeth. In addition, the third bristles 410 can be made of silicone material to prevent damage to the oral mucosa or gums, etc., but are not limited to this.

In one embodiment, since the brush head body 100, the tongue brush 300, the first bristles 120 and the second bristles 310 are all made of silicone, damage to the oral mucosa or gums can be prevented, but it is not limited to this.

The oral care rinsing toothbrush comprises the above-mentioned oral care rinsing toothbrush head, and also comprises an electric handle 500 and an electric toothbrush switch 510. By controlling the electric toothbrush switch 510, the electric source in the electric handle 500 is turned on, thereby causing the brush head to vibrate as a whole, thereby achieving cleaning of the oral cavity.

The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
