Description

Toothpaste discharge toothbrush

The present invention relates to a toothpaste dispensing toothbrush, and more particularly, to a toothpaste dispensing toothbrush in which the toothpaste of the handle is discharged to the bristles only when the toothpaste is stored after brushing the toothpaste in the handle.

In general, the toothbrush is used for brushing teeth, including a handle portion having a bristles on the tip and bristles planted on the bristles, and put a small amount of toothpaste on the upper side of the bristles and put the bristles into the mouth Brush your teeth while moving left and right. These toothbrushes must be provided with toothpaste in order to brush their teeth, so each household has the inconvenience of having to take toothpaste with a toothbrush, especially if you go out for travel or other reasons. There was also a problem to buy toothpaste.

In order to solve this problem, the applicant has invented Korean Patent Publication No. 10-2012-0039140 (toothpaste discharge toothbrush). 1 to 6 are views disclosed in Korean Patent Publication No. 10-2012-0039140.

As shown in Fig. 1 (perspective view) and Fig. 2 (sectional view), the prior art is provided with a toothpaste storage chamber 212 at the front end of the handle portion 210 is empty inside, using the compressed air in the air compression chamber of the rear end The piston 400 is pushed forward to discharge the toothpaste in the direction of the nipple (Nipple, 500) through the transfer path 222. The pumping device 300 is coupled to the distal end of the handle 210 to push air into the air compression chamber 211.

On the other hand, as shown in Figure 4, the nipple 500 is made of a flexible material, the interior is empty, the bottom is made of an upper plate member 520 formed with the nipple body 510 and the incision 522 is open. The toothpaste extruded through the transfer path 222 causes the nipple 500 to expand, and when the pressure inside the nipple 500 increases, the toothpaste is discharged through the cutout 522 of the upper plate member 520.

However, the cutout 522 of the conventional nipple 500 is opened by a small internal pressure when a predetermined amount or more pressure is applied by the pumping action of the pumping ball 320 to discharge the toothpaste to the outside. Therefore, it was difficult to control the toothpaste discharge.

Furthermore, when pumping with the pumping device 300, the toothpaste was continuously discharged through the incision 522. When the user inadvertently presses the pumping device 300 several times, more than one dose of toothpaste is discharged, which may lead to consumer dissatisfaction.

In addition, the nipple 300 accommodates the toothpaste as much as possible even if the toothpaste is pushed through the transfer path 222, while brushing, as shown in Fig. 6 (c), (d), by the incision by shaking It is ideal to discharge little by little to the hair transplanter 230 only when 522 is displaced. However, in the conventional nipple 500 structure, not only toothpaste flowed out through the cutout 522 even at a predetermined amount or more of internal pressure (toothpaste pressure), but the toothpaste was discharged through the cutout 522 even after brushing. . Therefore, there was also a problem that can not store a lot of toothpaste inside.

Therefore, when the toothpaste has reached the limit pressure of the nipple (maximum pressure that can withstand the incision of the nipple even when the internal toothpaste pressure is not opened), the toothpaste is no longer discharged even when the air is injected into the pumping device 300. The development of toothpaste dispensing toothbrush is not necessary. In addition, it is necessary to improve the structure that the nipple 500 can withstand the internal pressure as much as possible.

The present invention is to provide a toothpaste toothbrush that does not discharge any more toothpaste because the air inside the handle is not compressed even when pumped when the inside of the nipple reaches the limit pressure.

Toothpaste discharge toothbrush 1000, the handle portion 1210 is empty inside; A piston 1400 embedded in the handle part 1210; A pumping device 1300 coupled to the rear of the handle part 1210 to push the piston 1400 forward by air pressure; An extension part 1220 coupled to the front end of the handle part 1210 and having an internal conveying path 1222 communicating with the handle part 1210; A hair transplanting unit 1230 coupled to an end of the extension part 1220 and having a discharge hole 1232 communicating with the transfer path 1222; Bristles 1231 coupled to the tuft portion 1230; And nipples 1500 and nipple coupled to the discharge ports 1232 (see FIGS. 7 and 8).

The handle part 1210, the extension part 1220, and the hair transplanting part 1230 may be collectively referred to as a body part 1200. Body portion 1200 may be separated into several parts, it may be made of a single injection.

The nipple 1500, the lower portion is open, the nipple body portion 1510 of the flexible material is empty inside; Located on the upper portion of the nipple body portion 1510, the upper plate member 1520 of the flexible material to cover the upper portion of the nipple body portion 1510; It includes a cutout 1522 formed in the upper plate member 1520. (See FIG. 10)

A pumping ball 1320 made of a soft material is coupled to the pumping device 1300. The deformation pressure of the pumping ball 1320 is smaller than the limit pressure at which the cutout 1522 is opened by the pressure of the internal toothpaste. Therefore, before reaching the limit pressure, the pumping ball 1320 is deformed.

The upper plate member 1520 has a lower surface 1521 is convex downward. In addition, the thickness t1 of the central portion of the upper plate member 1520 is thicker than the thickness t2 of the edge.

In addition, a protruding edge 1530 is formed at an edge of the upper surface 1523 of the upper plate member 1520.

In addition, the lower wall 1511 of the nipple body portion 1510 is thicker than the upper wall 1512.

The handle portion 1210 is empty inside. Handle portion 1210 may be made of plastic injection.

The piston 1400 is guide-coupled to the inside of the handle portion 1210. The front of the handle portion 1210 is a toothpaste storage chamber 1212, the rear of the piston 1400, the air compression chamber 1211. When the piston 1400 presses the toothpaste stored in the toothpaste storage chamber 1212, the toothpaste moves to the front of the handle part 1210 (see FIG. 8).

The pumping device 1300 is coupled to the rear of the handle part 1210. The air pressure may be increased by pushing air into the air compression chamber 1211 using the pumping device 1300. This air pressure pushes the piston 1400 forward.

Pumping device 1300 is coupled to the handle portion 1210, the housing 1310, the soft material pumping ball 1320 coupled to the housing 1310, the pumping ball 1320 is coupled to the handle portion 1210 It consists of a valve 1330 located inside. A pumping hole 1322 is formed in the pumping ball 1320. When the pumping ball 1322 is closed and the pumping ball 1320 is pressed, air in the pumping ball 1320 enters the air compression chamber 1211 through the valve 1330. The valve 1330 blocks air flow in the reverse direction. Therefore, when the pumping ball 1320 is pressed, the air pressure of the air compression chamber 1211 is increased, and the piston 1400 moves forward. The pumping ball 1320 has a handle portion (3) having a thickness of an externally exposed portion. 1210) and thinner than the combined portion. Therefore, deformation of the pumping ball 1320 occurs in the part exposed to the outside (see Fig. 8).

When the pumping ball 1320 is continuously pressed, the air pressure in the air compression chamber 1211 increases. In response, the piston 1400 presses the toothpaste storage chamber 1212. However, when the pumping ball 1320 reaches the deformation pressure, it is no longer able to push air into the air compression chamber 1211. That is, when the deformation pressure is reached, air pressure acts on the deformation of the pumping ball 1320, as shown in FIG. 13, rather than pushing air into the air compression chamber 1211. Pumping ball 1320 is made of a soft material such as silicon, it is possible to control the deformation pressure by adjusting the type, thickness and the like of the material. (See FIG. 13)

An extension part 1220 is coupled to the front end of the handle part 1210. There is a conveying path 1222 inside the extension part 1220, the conveying path 1222 is in communication with the interior of the handle portion 1210. Accordingly, the toothpaste of the toothpaste storage chamber 1212 may move through the transfer path 1222.

The tip of the handle portion 1210 is inserted into the extension portion 1220. (See FIG. 8)

In the extension part 1220, a first protruding ring 1223 and a second protruding ring 1224 positioned outside the first protruding ring 1223 are formed outside. In addition, a third protruding ring 1213 and a fourth protruding ring 1214 positioned in front of the third protruding ring 1213 are formed at the tip of the handle part 1210. When the extension part 1220 and the handle part 1210 are coupled, the first protruding ring 1223 and the fourth protruding ring 1214 are strongly coupled, and the second protruding ring 1224 and the third protruding ring 1213 ) Are loosely coupled. Therefore, a toothpaste is filled between the 1st protrusion ring 1223 and the 4th protrusion ring 1214, this toothpaste hardens | cures and sealing is performed. (See FIG. 8)

The tuft portion 1230 is coupled to the end of the extension portion 1220. The hair transplanting unit 1230 is provided with a discharge port 1232 in communication with the transfer path 1222. The bristles 1230 are planted with bristles 1231 (see FIGS. 7 and 8).

Nipples 1500 and nipples are coupled to the discharge holes 1232. The nipple 1500 includes a nipple body part 1510 of a soft material having an open lower portion and an empty inside thereof; Located on the upper portion of the nipple body portion 1510, the upper plate member 1520 of the flexible material to cover the upper portion of the nipple body portion 1510; It includes a cutout 1522 formed in the upper plate member 1520. In addition, the upper plate member 1520 has a lower convex structure. Further, the thickness t1 of the central portion of the upper plate member 1520 is thicker than the thickness t2 of the edge (see FIG. 10).

The toothpaste reaching the discharge port 1232 is finally supplied to the bristles 1231 through the cutouts 1522 of the nipple 1500. In particular, the toothpaste is automatically discharged to the incision 1522 when stimulating the nipple 1500 while brushing. This process is explained with reference to the drawing of FIG. 12, and normally, the nipple 1500 is filled with the toothpaste like (a). At this time, when the air is pushed into the air compression chamber 1211 using the pumping ball 1320, the piston 1400 moves forward and supplies toothpaste to the nipple 1500. At this time, the cutout portion 1522 of the nipple 1500 should be held as much as possible without the toothpaste, toothpaste is discharged well when brushing later. When the nipple 1500 is shaken from side to side, as shown in FIGS. 12C and 12D, the lower surface of the cutout 1522 is shifted, and a gap is formed in the cutout 1522, and the toothpaste 1600 is interposed therebetween. ) Is discharged.

In the conventional nipple of FIG. 4, the incision is opened at a small tooth pressure inside, and the toothpaste is discharged to the outside. Even after brushing, there was a problem that the toothpaste is discharged.

In the nipple 1500 of the present invention, as shown in FIG. 10B, the upper plate member 1520 has a lower convex structure. In addition, the thickness t1 of the central portion of the upper plate member 1520 is thicker than the thickness t2 of the edge. When the pressure inside the nipple 1500 increases (when toothpaste is pushed in), it becomes a shape as shown in FIG. When the lower surface 1521 of the upper plate member 1520 is pressurized, it becomes flat as shown in FIG. At this time, the length of the cross section of the flattened lower surface 1521 (the straight lower surface 1521 of FIG. 10 (c)) is the lower surface of the lower surface when there is no pressure (the curve of FIG. 10 (b)). Lower surface 1521}. Accordingly, when the internal pressure of the lower surface 1521 of the upper plate member 1520 is increased, a force acts in the direction of the arrow of FIG. 10C, thereby cutting off the 1515 of the lower surface 1521. Is rather closed. On the other hand, the upper surface 1523 of the upper plate member 1520 maintains a straight shape when there is no internal pressure, and when the internal pressure increases, the upper surface 1523 is curved as shown in FIG.

As a result, the lower surface 1521 of the upper plate member 1520 closes the cutout 1522 as the internal pressure increases, so that the toothpaste is not discharged to the outside even at a high pressure. The non-discharged toothpaste is stored in the nipple body portion 1510 and the nipple body portion 1510 is convex. Since the nipple 1500 is made of a soft material such as silicon, it is possible to cope with any pressure increase.

On the other hand, the cutout 1522 of the nipple 1500 is completely open when the limit pressure is exceeded. That is, when the piston 1400 pushes out the toothpaste and the pressure inside the nipple 1500 increases, the cutout 1522 does not open until the limit pressure. The method of increasing the limit pressure is determined by the structural form of the upper plate member 1520, the thickness of the upper plate member 1520, the material of the nipple 1500, the material of the upper plate member 1520, and the like as in the present embodiment. . The cutout 1522 is preferably closed when there is no external stimulus. In the incision 1522 once opened, toothpaste is continuously discharged until the internal pressure disappears. Therefore, it is preferable that the internal pressure of the nipple 1500 does not increase until the threshold pressure.

Conventional pumping device does not have such a pressure control function, when the user excessively press the pumping device, through the incision, the toothpaste is continuously discharged. However, in the present embodiment, since the deformation pressure of the pumping ball 1320 is smaller than the limit pressure of the cutout 1522, before the nipple 1500 reaches the limit pressure, as shown in FIG. Deformation (just like pressing a balloon out of the way). As a result, no matter how much the pumping ball 1320 is pressed, the toothpaste is not discharged through the cutout 1522.

The toothpaste inside the nipple 1500 is discharged only when the nipple 1500 is shaken from side to side to stimulate it. As shown in FIG. 10C, the cutout 1522 is in a closed state without the toothpaste being discharged in a line contact state of the lower surface 1521. Thereafter, when the upper plate member 1520 is shaken as shown in FIGS. 12 (c) and 12 (d), the lower surface 1521 is opened and the toothpaste may be discharged to the cutout 1522.

When the nipple 1500 is touched while brushing, the cutout 1622 is opened while being displaced as shown in FIGS. 12C and 12D. At this time, the toothpaste 1600 is discharged in a small amount through the open incision (1522). The high-pressure toothpaste 1600 is stored in the nipple 1500. Until the internal pressure of the nipple 1500 is released, the toothpaste 1600 may be continuously discharged when the nipple 1500 is stimulated. According to the experiment, one pumping of the pumping ball 1320 was able to brush about five times.

In particular, since only a small amount of toothpaste 1600 is discharged through the nipple 1500, the toothpaste consumption is about 2g when brushed once. This is the recommended international dose, not only for dental health, but also for toothpaste savings.

On the other hand, the lower wall 1511 of the nipple body portion 1510 is thicker than the upper wall 1512. The lower wall 1511 is a portion coupled to the discharge port 1232, and the discharge hole 1232 is in the form of a short tube, and the lower wall 1511 of the nipple body part 1510 covers the outer circumferential surface of the discharge port 1232 and is engaged. do. When the pressure of the toothpaste 1600 is transmitted to the nipple 1500, the upper wall 1512 is thin and expanded, but the lower wall 1511 is not expanded to be coupled to the discharge port 1232.

In addition, a protruding edge 1530 is formed at an edge of the upper surface of the upper plate member 1520 of the nipple 1500. Thus, the cutout 1522 prevents further incision in the cutting direction.

Although the embodiment of the present invention has been described in detail above, this is only one embodiment, and thus, does not limit the claims of the present invention. Based on the present embodiment, modifications and additions made by those skilled in the art to the equivalent range will also belong to the scope of the present invention.
