Description

CROSSREFERENCE TO RELATED APPLICATION This application is a continuation of International Application No. PCT/CN 2025/114391, filed on Aug. 13, 2025, which claims priority to Chinese Patent Application No.2024223925561 titled “ORAL CARE ELEMENT AND ORAL CARE DEVICE” and filed to the State Patent Intellectual Property Office on Sep. 27, 2024, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD The present disclosure relates to the field of personal care technology, and more particularly, to an oral care element and an oral care device. BACKGROUND With the increasing awareness of oral health, integrated flushing machines have become preferred oral care devices for many families. The integrated flushing machines integrate toothbrushing functions of electric toothbrushes and flushing functions of oral irrigators, and thus can effectively improve cleaning effect and user experience. Oral care elements related to the oral care devices may include contact element carriers and brush handles with support bases, where the brush handles are connected to the contact element carriers through the support bases. The contact element carriers and the support bases typically are hard bases. When brushing teeth, the contact element carriers and the support bases are prone to collision with teeth during high-speed vibration, resulting in a phenomenon of “tooth striking” and adversely affecting the user experience. SUMMARY An objective of the present disclosure is to provide an oral care element and an oral care device. To achieve the above objective, in one aspect the present disclosure provides an oral care element, which at least includes a brush handle, a contact element carrier, and a surface covering element. The brush handle extending along a main extension line defines a flow guide channel and a first inlet and a first outlet communicating with the flow guide channel, where the first inlet and the first outlet are positioned at two opposite ends of the brush handle on the main extension line. The contact element carrier is mounted at one end of the brush handle adjacent to the first outlet along a direction intersecting with the main extension line, and the contact element carrier at least partially protrudes from the brush handle. The contact element carrier is provided with a bristle cluster extending along the direction intersecting with the main extension line and a water spray part communicating with the first outlet. The surface covering element is soft in texture, and covers around a side surface of an entirety formed by one end of the brush handle adjacent to the first outlet and the contact element carrier, and the contact element carrier is connected to the brush handle. Optionally, the brush handle has a support base at one end along the main extension line; and the support base is provided with a mounting slot along one side of the main extension line, where the first outlet is formed at a bottom of the mounting slot, and the contact element carrier is mounted in the mounting slot along a direction perpendicular to the main extension line. Optionally, the surface covering element further covers at least portion of a surface of the support base away from the contact element carrier. Optionally, the contact element carrier has a first segment and a second segment connected to each other, where a side surface of the first segment is positioned within a range of a side surface of the second segment, and a first step surface is formed between the side surface of the first segment and the side surface of the second segment. When the contact element carrier is mounted in the mounting slot along the direction perpendicular to the main extension line, the first segment is inserted into the mounting slot, and the first step surface is attached to a surface of the support base adjacent to the second segment. The side surface of the second segment and the side surface of the support base together constitute the side surface of the entirety formed by one end of the brush handle adjacent to the first outlet and the contact element carrier. Optionally, a surface of the second segment away from the first segment is provided with an attachment slot inwardly extending from the side surface of the second segment; and the surface covering element is filled in the attachment slot, such that the surface covering element partially covers the surface of the contact element carrier away from the support base. Optionally, the attachment slot includes a continuous annular slot extending along an edge of the contact element carrier. Optionally, the attachment slot also includes a plurality of inwardly extending slots inwardly extending from a side surface of the annular slot. Optionally, the water spray part and the contact element carrier form an integrated structure. Optionally, the water spray part protrudes from a surface of the contact element carrier away from the support base, and the water spray p
