The present invention is an oral irrigator comprising a pump, a discharge nozzle and a pressure control. The pump has a generally constant operating speed and feeds the discharge nozzle. The pressure control is adapted to modify a discharge pressure at the nozzle without a significant change in pump speed. The pressure control modifies a level of fluid flow restriction between the pump and the nozzle. The modification of the level of fluid flow restriction is accomplished by modifying aspects of a fluid flow path extending through the pressure control. The aspects modified include the diameter, length and / or number of direction changes of the fluid flow path.

A pump for an oral irrigator includes a pump chassis, an eccentric end plate movably connected to the pump chassis, a first alignment shaft connected to the pump chassis, a second alignment shaft connected to the eccentric end plate, a first gear rotating around a longitudinal axis of the first alignment shaft, and a second gear engaging the first gear and rotating around a longitudinal axis of the second alignment shaft. By selectively moving the eccentric end plate relative to the pump chassis selectively moves the second gear relative to the first gear.

According to one broad aspect of one embodiment of the present invention, disclosed herein is a hand held oral irrigation device having a tip for dispensing fluids. In one example, an oral irrigation device includes a body portion, and a reservoir for storing fluids, wherein the body and / or the reservoir define a first major diameter at a lower end of the oral irrigation device, and define a second major diameter at an upper end of the oral irrigation device, the first major diameter being larger than the second major diameter. In this example, by providing such a geometry for the device, a user can grasp the device with one hand about the second major diameter during use. In another example, the body includes a pump for pumping fluids from the reservoir to the tip, wherein the pump includes an inlet valve and an outlet valve, the inlet valve including a reed valve made of flexible fabric material. The outlet valve may also include a reed valve made of flexible fabric material.

A structure for separating a discharge nozzle of an oral irrigator includes a first discharge path formed in one side of the irrigator body, a water pressure control lever rotatably arranged above the first discharge path and having a second discharge path in the other side of the irrigator body, a release button section provided on an upper portion of the water pressure control lever and into which the discharge nozzle is inserted and engaged, and configured, when pushed, to be bent so as to release the engaged discharge nozzle, and a locking section provided in the release button section and water pressure control lever to control a pushing operation of the release button section depending upon whether the first discharge path is open or blocked.

The invention relates to a portable dental flosser. The portable dental flosser can be used in two ways according to different needs of customers. One is a dental flosser with a water tank, and the other is a dental flosser without a water tank. , the overall structure of the device is ingeniously designed, compact, and low in cost. This technical solution overcomes the defects in the prior art, and can perform oral cleaning according to different needs and preferences of users to meet the requirements of different customers.

A oral irrigator device (10) for cleaning teeth, including a system (14) for producing a stream of liquid / air bursts and a nozzle (16) connected to the system, and through which the stream of liquid / air bursts are directed. The nozzle can include a guidance tip (26) including a base portion (30), a tip portion (28), and an orifice (31) through which the stream of liquid / air bursts exits at a flow output pattern, and a flow output pattern selection mechanism (90, 90') connected to or positioned within the guidance tip. A flow output pattern selection mechanism can be configured to be selectively actuated and to vary, upon the actuation the flow output pattern between a first flow output pattern to at least a second flow output pattern.

The invention discloses an oral irrigator. The oral irrigator comprises a shell, an oral irrigation part and a water nozzle part, the oral irrigation part is mounted in the shell and provided with a water inlet and a water outlet, and the water nozzle part communicates with the water outlet of the oral irrigation part; and a winding mechanism and a water pipe capable of being bent and wound are further included. The water pipe can be wound through the winding mechanism, the occupied space of the water pipe is reduced, carrying, packaging and transporting are convenient, and the loss of the water pipe can further be avoided; and the water pipe capable of being bent and wound is adopted, thus the second end of the water pipe is conveniently placed in a container filled with water or connected with a water source, and using occasions are wide.

A nasal nebulizer contains a main canister with at least one air exit port and an insert with at least one fluid channel. The fluid channel ends in a common bell housing above a base of the insert, which rests within the canister. The insert and the canister may form one integral unit for single usage, where a cap plugs the air exit port and the fluid channel, allowing for the transport or long-term storage of fluids within the nebulizer device. The insert may include an extension extending out to the canister and a vertical groove may extend down the fluid channel to a hole in the extension, which upon use helps create a vacuum that pulls in deflected fluid for re-use. The nebulizer may also contain a filter surrounding the tube portion near the top of the canister to catch any extraneous matter expelled from the nose during usage.

The invention relates to a water pump structure of a portable oral irrigator. The portable oral irrigator comprises an oral irrigator host, wherein the oral irrigator host comprises a housing and a water pump assembly; the water pump assembly is arranged in the housing and is provided with a pump body, a drive motor, a water outlet nozzle and a water inlet nozzle; the housing is provided with a water inlet and a water outlet corresponding to the water outlet nozzle and the water inlet nozzle separately; the drive motor is vertically arranged; an output shaft of the drive motor is in transmission connection with the pump body through a straight gear and an end surface gear; the end surface gear is vertically and rotationally arranged in the housing; the pump body comprises a pump cylinder, a piston rod and a pumping piston head; the pump cylinder is a three-way pipe; the pumping piston head is arranged in one end of the pump cylinder and the other two ends of the pump cylinder are communicated with the water outlet nozzle and the water inlet nozzle respectively; and one end of the piston rod is connected with the pumping piston head and the other end is in eccentric running fit with the end surface gear. The pumping piston head is controlled through an eccentric driving mechanism to continuously move in the pump cylinder in a reciprocating manner, so that continuous pumping is achieved to reach the target of reliably working.
