Disclosed is an oral-care sputum suction tube, including a housing, a water suction tube, a water intake tube, a toothbrush head, and a switch capable of controlling the flow of the water suction tube. A water suction opening provided on the toothbrush head is corresponding to a water suction opening provided on the housing, and a water intake opening provided on the toothbrush head is corresponding to a water intake opening provided on the housing. The switch is mounted in a switch mounting groove provided on a hand-held portion of the housing. The switch includes a rolling wheel and a slope plate. The rolling wheel is mounted in the switch mounting groove, and the water suction tube is mounted between the rolling wheel and the slope plate. Because the water suction tube and the water intake tube are separated, sucked sputum flows away through a sealed passage, thereby avoiding cross-infection.

Provided is a toothbrush having suction function and washing function, and the toothbrush includes a toothbrush rod including a head portion and a handle portion, a brush disposed at the head portion, a through-hole portion formed at the head portion to supply cleaning water to an oral cavity or suction in dirty water from the oral cavity, a guide tube disposed within the toothbrush rod and connected to the through-hole portion to deliver the cleaning water to the through-hole portion or deliver the dirty water suctioned in through the through-hole portion to the outside, and an external main body to supply the cleaning water to the guide tube and to receive the dirty water from the guide tube.

A shower brush system that includes an elongated body and an angularly adjustable showerhead with a combination cleaning surface and water dispersal system. The showerhead can be adjusted to clean the body or the bathing facility. Embodiments of the showerhead may include a removable insert that allows the user to choose from various brush heads or cleaning surfaces designed for different applications. These inserts can be removed, replaced, or disposed of when necessary. The shower brush systems of the present invention provide versatile and customizable cleaning solutions for users of and in a tub or shower.

Provided is a dental cleaning device. In the device, by arranging the water pump, the mixing mechanism and the rotating blade, clean water in the water tank enters the input pipe through the first hose and the three-way valve under the action of the water pump, and toothpaste in the toothpaste chamber also enters the input pipe through the three-way valve under the action of the toothpaste pump, and the mixture of clean water and toothpaste enters the mixing chamber through the input pipe to drive the rotating blade to rotate, so that toothpaste and water may be fully mixed, and toothpaste may be effectively prevented from being blocked in the electric toothbrush.

An agitation device that uses a variety of mechanical, acoustic, electrical, and chemical media in order to effectively remove biofilm from an infected implant. The brush head embodiments include numerous shapes and sizes tailored for specific applications. Irrigation, suction, drug delivery and capture capabilities are also provided.

A device for the surgical cleaning of infected implants, the device containing a brush head containing a bristle region having a plurality of bristles; a supply element configured to transport a cleaning liquid to the brush head; a discharge element configured to remove liquid from the brush head; and a connecting element configured to releasably connect the supply element and the discharge element to an external lavage device.

A sealant application nozzle comprises a manifold with a incurvate face; bristles extending outward from the incurvate face; and channels within the manifold culminating in outlets exiting through the incurvate face to dispose sealant onto the incurvate face and base of the bristles.

A nozzle structure with a plurality of bristle bunches includes a mouth-shaped casing and a plurality of bristle bunches. The mouth-shaped casing has a first end portion with an air inlet and a second end portion opposite to the first end portion. The second end portion has a plurality of outlet pores arranged in parallel and a plurality of bristle pores. Each of the outlet pores connects to the air inlet via a ventilated space inside the mouth-shaped casing, and the plurality of bristle bunches are implanted in the bristle pores of the mouth-shaped casing. In addition, the bristle bunches protrude further out from the outlet pores.

A solar panel cleaning system includes a brush connected by a hose to a fluid supply. The brush has scrubbing material, such as bristles, attached to a brush body for mechanically cleaning the surface of the solar panel. The width of the contact surface of the scrubbing material may be equal to the width of the solar panel, so that the solar panel may be cleaned with only upward and downward strokes. The brush body may further support a fluid manifold that receives the fluid from the fluid supply. The fluid manifold may include nozzles that emit the fluid under pressure onto the solar panel. The nozzles may project both frontward and rearward of the brush body so that the fluid sprays off the solar panel in front of and behind the brush. Spray patterns of the nozzles may overlap and impinge the entire width of the solar panel.

Disclosed herein is an oral care machine including: a tank for storing water; an ozone generator for generating ozone, the ozone generator mounted in the tank, wherein generated ozone mixes with water stored in the tank; a processing cartridge for treating exhaust gas of ozone generated by the machine when ozone is mixed with water, the processing cartridge mounted on the tank; a water pump for transporting treated water; and a handle for delivering the treated water to a desired location.
