Description

Technical Field

[0001] The utility model relates to the technical field of oral care, in particular to a negative pressure suction oral care device. Background Art

[0002] The oral cavity refers to the mouth of the human head, including the cavity formed by the lips, teeth, tongue, cheeks, hard palate, soft palate and other tissues. The oral cavity is the entrance to the digestive system and one of the organs for language communication. In the oral cavity, food is prepared for digestion through processes such as chewing and mixing with saliva. At the same time, the oral cavity is also an important place for the vocal cords to make sounds. The tongue and teeth work together to enable us to make various sounds. The oral cavity is also closely related to overall health. The quality of oral hygiene directly affects oral health and overall health. After oral surgery, cleaning and care in the oral cavity is the key to recovery.

[0003] A Chinese patent with publication number CN219089724U discloses a negative pressure suction oral care device, which has a semicircular cleaning head. The cleaning head can be used to perform cleaning and care operations inside the patient's oral cavity, and the cleaning liquid is sprayed out through the liquid outlet on the surface of the cleaning head, and the waste liquid generated after oral cleaning is sucked into the waste liquid collection area through the liquid suction hole, which is convenient for the caregiver to operate.

[0004] There are many patients in the department, and the oral care device needs to perform oral cleaning for many patients every day. However, the cleaning head in the above-mentioned patent cannot be disassembled and replaced, which leads to cross-infection when many patients use it, and increases patients' aversion to oral cleaning; and the cleaning liquid required for oral cleaning is not much, so after the inside of the shell is filled with cleaning liquid, the weight is still relatively light, and medical staff are likely to pull the first bellows and the second bellows during use, which may easily cause the shell to tip over, affecting the user experience.
