Description

Red teeth

The present invention relates to a red teeth device, and more particularly to a red teeth device capable of improving the efficiency of cleaning teeth.

Residues of food left in the teeth are prone to tooth decay and periodontal disease. Therefore, timely removal of residual food in the mouth is an important measure to prevent oral diseases.

There are many types of common oral cleaning aids, such as toothbrushes, dental floss or red teeth. The following description of the present invention is particularly directed to a red teeth device that removes vegetable residue and tartar from the teeth by the principle of water flow impact.

Moreover, the conventional red teeth have been widely seen in many patent pre-existing cases. Typical cases are such as Chen Jinyujun's announcement No. 429779, "Improvement of Red Teeth Structure"; or Shi Chenglongjun's Announcement No. 579843 "Red Teething Machine" "Structural improvement"; or Lu Songsen Jun's certificate No. M249623 "Improved structure of red teeth". The red teeth disclosed above have been patented in Taiwan because of their unique features; however, the grips of each of the red teeth are nothing more than a hollow tube body formed integrally with a water inlet at both ends of the tube body. And a nozzle, and a water passage connecting between the water inlet and the nozzle, the structure is designed to allow the external water source or the cleaning liquid to flow in first from the water inlet, and then transmitted through the water guiding channel, and finally orthogonally ejected by the nozzle Oral cleaning is performed around the user's teeth.

However, the grip of the above-mentioned red teether is integrally formed with the nozzle, and the nozzle can only be designed as a single-hole erupting water flow during manufacture, so that the direction of the water jet that can be ejected by the nozzle is limited to straight orthogonal, and the water erupts in the oral cavity. The target (such as teeth) covers a small area, so the above-mentioned red teeth are difficult to achieve rapid and complete removal of the effect on the narrow and complex oral environment and the long-standing tartar.

The main object of the present invention is to provide a red teeth device, wherein the nozzle of the red teeth has a plurality of nozzles, so that the water flow outflow system exhibits a multi-tube joint state, effectively clears the perennial tartar and improves the oral cleaning efficiency.

In order to achieve the above object, the present invention provides a red teeth device comprising a hollow tube body and a nozzle, wherein the two ends of the hollow tube body are respectively a water inlet and a water outlet, and between the water inlet and the water outlet a nozzle is provided; the nozzle has a plurality of nozzles which are inclined obliquely and correspondingly inclined to each other, and the water jets are sprayed by the plurality of nozzles in a concentrated manner, multi-angle and multi-tube manner, so as to obtain objects in the oral cavity (for example, Recalcitrant tartar, food residue slag) receives a multi-angle and obliquely cohesive strong water flow, a large area of water column impact, effective removal of perennial tartar and improve oral cleaning efficiency.

Detailed construction, features, assembly or use of the present invention will be described in the detailed description that follows. However, it should be understood by those of ordinary skill in the art that the present invention is not limited by the scope of the invention.

The technical contents and features of the present invention will be described in detail below with reference to the accompanying drawings, in which: FIG. 1 is a preferred embodiment of the present invention, the handle of the red teeth is connected to the water source. 2 is a schematic exploded view of a handle and a head of a red toothbrush according to a preferred embodiment of the present invention; a third view is a rear plan view of the head of the second figure; and a fourth view is a combined perspective view of the third figure; The fifth figure is a cross-sectional view of the fourth line of Fig. 5-5.

Referring to the first to fifth figures, the red teeth device 10 according to a preferred embodiment of the present invention mainly comprises a hollow tube body 20 and a nozzle 30.

The hollow tubular body 20 is generally a long tubular hollow body. The two ends of the tubular body 20 are respectively a water inlet 21 and a water outlet 22, and a water inlet passage 25 is provided between the water inlet 21 and the water outlet 22. . The water inlet 21 is coupled to one end of the connecting pipe A, and the other end of the connecting pipe A is connected to the water supply source. It should be noted that the first embodiment of the present embodiment uses a faucet as an example, but is not limited thereto. It is an equivalent of the present invention as long as it can provide a connected liquid-filled container; the inner edge of the water outlet 22 is provided as an internally threaded section.

The nozzles 30 are connected to the water outlets 22 of the hollow tube body 20 in a detachable manner. This embodiment is not limited to a threaded screw. The nozzle 30 is roughly divided into a front and a rear section. The rear section has a joint portion 31 connected to the water outlet 22. The outer edge of the joint portion 31 is an external thread segment, and the front portion of the spray head 30 is formed as an umbrella nozzle. 33. The invention is unique in that the exposed surface of the nozzle 33 is formed with three nozzles 34 (in the present embodiment, although it is represented by three holes, it is not limited thereby, and the number of holes of the other two holes, four holes or more is In an equivalent implementation of the present invention, the nozzles 34 are arranged in a ring shape and the adjacent two are concentrated obliquely inwardly at equal intervals. In more detail, each of the nozzles 34 is formed with a passage 35 in the direction from the outer end to the inner end of the nozzle 30 for connecting the water flow from the water outlet 22, wherein the passages 35 are separated by two sections. The first and second communication segments 351 and 352 of the radial dimension are formed, and in the present embodiment, the inner diameter of the first communication segment 351 is smaller than the second communication segment 352. It should be further noted that the long axial directions of the communicating sections 351 and 352 of the nozzles 34 are substantially non-parallel to the axial center of the nozzle 30, that is, from the outer end of the nozzle 30 to the inner end. The direction is gradually inclined to be carried away away from the central long axis of the nozzle 30; in reverse, the longitudinal direction of the channel 35 of each nozzle 34 is concentrated toward the outer end of the nozzle 30 in an inclined manner, and finally the three nozzles The 34th channel 35 long axis will intersect each other at an appropriate distance in front of the nozzle 30.

In addition to the above, it should be noted that the second connecting sections 352 of the three channels 35 of the three nozzles 34 of the nozzle 30 of the present invention are further connected to the pressurized water storage chamber 353 toward the water outlet 20 for Each of the nozzles 34 is provided with a stored value of pressurized kinetic energy.

According to the detailed description of the above structure, when the present invention is used, the nozzle 30 first uses the water storage chamber 353 to accumulate the water flow and pressurizes the kinetic energy, and then passes through the second connecting portion 352 of the larger diameter of each channel 35 and the first connection of the smaller diameter. The design of the passage section 351 continues the flow pressure in the pressurized passage 35, and the multi-stage water flow boosting structure allows the water flow to flow out of the spout 34 to present a powerful water column; most importantly, the passage 35 of each spout 34 is long. The axial direction is obliquely concentrated toward the center of the outer end of the nozzle 30, and the multi-angle and multi-tube ejecting water column can make the target in the oral cavity (such as stubborn tartar and food residue) receive multi-angle and oblique inward. The powerful water flow has a large area of water column impact, which effectively removes tartar and improves oral cleaning efficiency.

In the following, it is to be understood that the detailed description of the present invention is provided to illustrate the technical content and features of the present invention. Those skilled in the art of the present invention will understand the present invention.
