technical field

The invention relates to a tooth cleaning device, in particular to an oral cleaning device capable of generating water column to clean teeth.

Background technique

In the current oral cleaning device, the nozzle head for water outlet is mostly only provided with a single water channel to spray a single concentrated and powerful water column for the user to clean between the teeth or between the teeth and the gums; for example, Taiwan, China Announcement No. M462588 "Structure of Control Valve for Portable Teeth Flossing Machine", No. M461410 "Flossing Machine with Manual Control of Water Volume", No. M456178 "Structure Improvement of Teeth Flosser" and No. M443508 "Water Vibration Teeth Flossing Machine" Existing oral cleaning devices disclosed in patent cases such as "machine" are all like this.

But, because of these existing oral cleaning devices, the nozzle head can only spray a single water column, so the tooth cleaning area that can be provided is limited to a small range. The position in the oral cavity can complete the action of cleaning teeth, so the operation time of cleaning teeth is long, resulting in poor cleaning efficiency.

In addition, it is worth mentioning that please refer to Figure 1, which is a flushing toothbrush 9 disclosed in China Taiwan Announcement No. M350281 "Automatic Flushing Toothbrush". The existing flushing toothbrush 9 includes a toothbrush handle 91 And a replacement bristle unit 92; the toothbrush handle 91 has a handle body 911 and a handle head 912, the handle body 911 is provided with a first water channel 913 and a second water channel 914, wherein the first water channel 913 is provided with a first The water volume adjustment button 915, the second water channel 914 is provided with a second water volume adjustment button 916, the handle 912 is provided with a receiving space 917 communicating with the first water channel 913, and the front end of the handle 912 is provided There is a nozzle 918 communicating with the second waterway 914; the replacement bristle unit 92 has a base plate 921 and a number of bristles 922, the base plate 921 is assembled and engaged in the accommodation space 917 of the handle 912, the base plate 921 A water inlet hole 923 communicating with the first water channel 913 is provided, and several openings 924 are provided on the outer surface of the base plate 921 for the number of bristles 922 to plant.

Accordingly, when brushing teeth with the existing flushing toothbrush 9, the first water channel 913 is controlled by the first water volume adjustment button 915 to be opened, and the second water channel 914 is controlled by the second water volume adjustment button 916 to be closed. , so that the water flow can only flow out from the number of openings 924 of the base plate 921 through the first water channel 913 and the water inlet 923, so as to form several water columns between the number of bristles 922 for the user to moisten the mouth, brush teeth, Rinse mouth; this moment, this nozzle 918 does not come out of water.

Again, when desiring to use the existing flushing toothbrush 9 to flush teeth, the first water channel 913 is controlled by the first water volume adjustment button 915 to be closed, and the second water channel 914 is controlled by the second water volume adjustment button 916 to be opened. , so that the water flow can only pass through the second water channel 914 and the nozzle 918 to spray a water column from the front end of the toothbrush handle 91 for the user to rinse his teeth; at this time, no water will flow between the bristles 922 .

It can be seen that this existing flushing toothbrush 9 is combined with the function of brushing teeth with a toothbrush and flushing teeth with a water column, and these two functions are selectively carried out rather than synchronously during use, so in terms of its teeth flushing function, it is still It only has a single water channel (ie the second water channel 914 ) and can only spray a single water column, so it also has the aforementioned disadvantage of poor tooth cleaning efficiency when flushing teeth.
