Description

Technical Field

[0001] The utility model relates to an oral cleaning device, in particular to a nozzle which can be bent, changed and fixed in shape. Background Art

[0002] Existing oral rinsers or water flossers generally have a nozzle, which is usually designed in a long strip shape to facilitate insertion into the oral cavity for rinsing. However, existing nozzles are made of hard plastic, and the shape or curvature of the nozzle cannot be changed according to the needs of the user. For example, when it is necessary to rinse the dead corner of the oral cavity, the nozzle cannot change the spray direction. The user either swings the entire oral rinser or water flosser to obtain a suitable direction for cleaning, or swings the head to obtain a suitable position. The former is likely to change the water level of the water tank in the oral rinser or water flosser, causing water outage and difficult to control the water flow; the latter is likely to put the head in an uncomfortable position, which is less comfortable; and it is also likely to cause the cleaning to fail to reach the desired position, resulting in poor cleaning effect.

[0003] The utility model aims to provide a nozzle which can be bent, changed and fixed in shape.

[0004] Another object of the utility model is to provide an oral cleaning device with a nozzle that can be bent, changed and fixed in shape, simple water flow control, convenient and comfortable use and better cleaning effect.

[0005] In order to achieve the above-mentioned purpose, the nozzle provided by the utility model includes a pipe, the pipe has a channel for fluid to pass through, the pipe includes a sheath and a bending shaping tube, the sheath is wrapped around the outside of the bending shaping tube, and the pipe can be bent and changed in shape and fixed in the shape.

[0006] Compared with the prior art, since the nozzle of the utility model is composed of a sheath and a curved shaping tube, the sheath is wrapped around the outer side of the curved shaping tube to protect the curved shaping tube, and the curved shaping tube has the characteristic of being able to bend and change its shape at will, so that the nozzle can be bent and changed in shape and fixed in the shape. Therefore, the user can adjust the water spraying angle of the nozzle according to his own needs, so as to achieve the purpose of controlling the direction of the water flow, and the control is very simple and convenient, which makes the oral rinser more convenient and comfortable to use, and the water flow can be sprayed to a position that is usually difficult to reach, and the cleaning effect is better.

[0007] Preferably, the pipeline further comprises an inner sleeve, which is arranged in the curved shaping pipe. By arranging the inner sleeve, the curved shaping pipe can be further protected, and the curved shaping pipe can be prevented from being corroded by the liquid in the channel, thereby extending the service life of the nozzle.

[0008] Preferably, the curved shaped tube is a corrugated tube, a gooseneck tube or an interlocking metal hose.

[0009] Preferably, the sheath is made of silicone, silicone rubber, soft polyethylene, polyethylene, fluorocarbon, polyurethane, ester or olefin elastomer material.

[0010] Specifically, the inner sleeve is a flexible structural layer.

[0011] Specifically, the inner sleeve is made of silicone, silicone rubber, soft polyethylene, polyethylene, fluorocarbon, polyurethane, ester grade or olefin elastomer material.

[0012] An oral cleaning device comprises a cleaning device and a nozzle, wherein one end of the nozzle is connected to a water outlet end of the cleaning device. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to explain the technical content, structural features and effects achieved by the present invention in detail, the following is a detailed description in conjunction with the implementation modes and the accompanying drawings.

[0018] like Figures 1 to 4As shown, the oral cleaning device 100 of the utility model comprises a nozzle 1 and a cleaning device 2, one end of the nozzle 1 is connected to the water outlet end of the cleaning device 2. The nozzle 1 comprises a pipe 11, the pipe 11 has a channel 12 for fluid to pass through, the pipe 11 comprises a sheath 111 and a bending shaping tube 112, the sheath 111 is wrapped around the outer side of the bending shaping tube 112, the pipe 11 can be bent and changed in shape, so that the direction of water spraying can be changed, and the pipe 11 can be fixed in the shape. The sheath 111 is made of silicone, silicone rubber, soft polyethylene, polyethylene, fluorocarbon, polyurethane, ester or olefin elastomer material. The bending shaping tube 112 is a metal shaping hose, for example, it can be a bellows / metal bellows, a gooseneck or an interlocking metal hose, but is not limited to the above. Any hose that can be bent and shaped to change the direction of water flow is within the scope of this solution; the metal bellows, gooseneck and interlocking metal hose are prior arts, and their specific structures are well known to those skilled in the art and will not be described in detail here.

[0019] Please see again Figures 2 to 4 The pipe 11 also includes an inner sleeve 113, which is arranged in the curved shaping tube 112, and the channel 12 is formed in the inner sleeve 113. By providing the inner sleeve 113, the curved shaping tube 112 can be further protected to prevent the curved shaping tube 112 from being corroded by the liquid in the channel 12, thereby extending the service life of the nozzle 1. The inner sleeve 113 is a flexible structural layer, which can be made of a flexible polymer material. The material of the inner sleeve 113 can be the same as or different from that of the sheath 111. Specifically, the inner sleeve 113 is made of silicone, silicone rubber, soft polyethylene, polyethylene, fluorocarbon, polyurethane, ester grade or olefin elastomer material.

[0020] Compared with the prior art, since the nozzle 1 of the utility model is composed of a sheath 111 and a curved shaping tube 112, the sheath 111 is wrapped around the outer side of the curved shaping tube 112 to protect the curved shaping tube 112, and the curved shaping tube 112 has the characteristic of being able to bend and change shape at will, so that the nozzle 1 can be bent and changed in shape and fixed in the shape. Therefore, the user can adjust the water spraying angle of the nozzle 1 according to his own needs, so as to achieve the purpose of controlling the direction of the water flow, and the control is very simple and convenient, which makes the oral rinser 100 more convenient and comfortable to use, and the water flow can be sprayed to a position that is usually difficult to reach, and the cleaning effect is better.

[0021] The structure of the cleaning device 2 involved in the oral cleaning device 100 of the present invention is well known to those skilled in the art and will not be described in detail herein.
