Description

Red teeth cleaning structure

This creation is about a technical field that can be used to clean the clean structure of teeth, glasses or other items, especially a two-stage supercharging effect that can be sprayed with a stronger force by the spiral speed increase and the reduction of the diameter. The water column is used to further improve the flushing efficiency of the teeth cleaning structure.

It is a common practice to use a pressurized water column to clean the surface and the gaps of teeth, glasses, sinks or other items in daily life. For example, as disclosed in Taiwan Patent Nos. M249623 and M288180, the structure mainly includes a head that can be easily held by a hand and attached to one end of the handle. Wherein the handle is a hollow tube body, and the other end of the handle can be connected to a water tap or other device by a water pipe for introducing an external water source or a cleaning liquid. The spray head has a water flow passage that communicates with the pipe in the hollow pipe body and gradually narrows and penetrates to the water discharge end. In this way, the flow of the pressurized water can be generated by the gradually decreasing water outlet passage in the nozzle, so that the sprayed water column can produce a flushing and cleaning effect on the teeth and the teeth. However, the conventional red-handling device uses only one of the nozzles to gradually reduce one of the water outlet channels to produce a water flow pressurization effect is very limited, so the washing and cleaning effect is poor.

Conventional red teeth have the problem that the water column that is ejected is weak and the flushing cleaning efficiency is poor.

The present invention provides a tooth cleaning structure comprising a handle, a spray head and a flow guiding block. The two ends of the handle respectively have a water inlet joint and a water outlet joint, and the inside of the handle has a water inlet passage communicating with the water inlet joint and the end surface of the water outlet joint. One end of the nozzle has a joint portion for being coupled to the water outlet joint, and an end surface of the joint portion has a receiving groove communicating with the water inlet flow passage. The nozzle is opposite to one end surface of the joint portion and has a water outlet hole penetrating into the pocket and having a smaller aperture. The guiding block is coupled to the receiving groove, and the peripheral surface of the guiding block has at least one guiding groove which is spirally and penetrates to both end faces, and the guiding groove is matched with the groove wall of the receiving groove And a spiral flow path is formed.

The tooth cleaning structure of the present invention can introduce an external water source through the water inlet channel, and then use the spiral flow channel to form a spiral flow path formed by the groove wall of the groove to generate a spiral through the water flow. The first stage of supercharging is accelerated, and then the water is passed through the smaller aperture outlet to produce a second stage boosting effect by limiting the diameter. In this way, the two-stage supercharging effect of the spiral speed increasing and the limiting diameter can make the water column which is sprayed out have a stronger force. Therefore, the flushing of the water column with the stronger force can greatly improve the flushing efficiency and the cleaning effect.

Referring to Figures 1 through 6, it is shown that the tooth cleaning structure of the present invention includes a handle 10, a nozzle 20 and a flow guiding block 30. The handle 10 has a water inlet joint 11 and a water outlet joint 12 at both ends, and has a water inlet passage 13 communicating with the water inlet joint 11 and the end surface of the water outlet joint 12 in the interior of the grip 10. . The water inlet joint 11 has a small outer diameter, and the circumferential surface thereof has an external thread for screwing a screw joint 41 at one end of a water pipe 40, and the water inlet passage 13 penetrates to the water inlet joint 11 End face. The other end of the water pipe 40 is provided with a connector 42 for connection to a faucet 43 for introducing an external water source into the water inlet passage 13 of the handle 10. The end face of the water outlet joint 12 has a screw hole 14 disposed perpendicularly to the inlet water flow passage 13 and communicating therewith. In the present creation, the screw hole 14 can also form a specific angle with the water inlet flow path 13.

The nozzle 20 has a tapered shape, and an inner end thereof has a joint portion 21 of a small outer diameter, and a peripheral surface of the joint portion 21 has an external thread for being screwed into the screw hole 14. The end surface of the joint portion 21 has a receiving groove 22 communicating with the water inlet flow passage 13, and the inner end portion of the receiving groove 22 forms a tapered flow path 23 whose diameter is gradually reduced. The outer surface of the nozzle 20 has a water outlet hole 24 penetrating into the pocket 22 and having a smaller aperture.

The guiding block 30 is fixedly fixed in the receiving slot 22, and the guiding flow is The peripheral surface of the block 30 has at least one flow guiding groove 31 which is spirally formed and penetrates to both end faces. The flow guiding groove 31 is fitted to the groove wall of the receiving groove 22 to form a spiral flow path. In the present creation, the number of the flow guiding grooves 31 on the flow guiding block 30 is preferably three.

Since the creation of the tooth cleaning structure by the water inlet channel 13 After the external water is introduced, the spiral flow path formed by the spiral flow guiding groove 31 and the groove wall of the groove 22 can be used to generate a first-stage supercharging effect of the spiral acceleration through the water flow, and then borrow The second-stage supercharging effect is generated by the small-diameter water outlet hole 24 in a manner of limiting the diameter. In this way, after the two-stage supercharging effect of the spiral speed increasing and the limiting diameter, the water column that can be ejected has a stronger force, so that the flushing of the water column with the stronger force can greatly improve the flushing efficiency and the cleaning effect. In particular, the water column is so strong that it is used not only to wash teeth and teeth, but also to clean the dirt on glasses, toothbrushes and other items and to wash the scale on the sink and faucet. Can get good cleaning results.
