Description

Technical Field

[0001] The utility model relates to the field of daily necessities, and more specifically, to a multi-head toothbrush. Background Art

[0002] A toothbrush is a cleaning product, a handle-type brush, which is used to add toothpaste to the brush and then repeatedly brush various parts of the teeth to maintain oral hygiene. Common toothbrushes are usually single-headed, and there are also double-headed or triple-headed toothbrushes, collectively referred to as multi-headed toothbrushes. Compared with single-headed toothbrushes, multi-headed toothbrushes do not need to repeatedly adjust the angle of the toothbrush when brushing teeth, and can clean teeth in multiple directions at one time. For example, the multi-headed toothbrush with patent number CN206950242U is a type of multi-headed toothbrush.

[0003] This type of multi-head toothbrush generally has the following problems: the spacing between the brush heads is not easy to adjust, and the spacing between the brush heads cannot be adjusted according to user needs. If the spacing is too small, the brush heads are likely to damage the gums. If the spacing is too large, it is difficult for one of the brush heads to touch the tooth surface, which is not convenient for cleaning the teeth. After using it for a period of time, the bristles will wear out, which will also cause the spacing between the brush heads to increase, and the spacing cannot be finely adjusted. During use, the side brush heads have inconsistent wear degrees of their bristles due to their inclined angles. Only one side is severely worn, while the bristles on the other side are in relatively good health. It is a waste to directly remove the side brush heads, so the structure of the multi-head toothbrush needs to be improved. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a multi-head toothbrush, which uses a metal sheet to support the auxiliary brush heads. The plasticity of the metal sheet is higher than that of plastic, which makes it easy to adjust the distance between the brush heads.

[0005] To solve the above problems, the utility model adopts the following technical solutions.

[0006] A multi-head toothbrush comprises a brush handle 101 and an auxiliary brush head 103. A main brush head 102 is arranged on the top of the brush handle 101. Bristles 106 are arranged on one side of the auxiliary brush head 103 and the main brush head 102. A socket 105 is opened through the inside of the main brush head 102. A socket 105 is also opened through the inside of the auxiliary brush head 103. There are two auxiliary brush heads 103. A metal sheet 104 is installed through the inside of the main brush head 102 corresponding to the socket 105.

[0007] Furthermore, the two auxiliary brush heads 103 are respectively installed at two ends of the metal sheet 104 through the sockets 105 .

[0008] Furthermore, positioning grooves 151 are evenly formed on the inner wall of one side of the socket 105 .

[0009] Furthermore, a positioning protrusion 141 is provided at the center and end of one side of the metal sheet 104 , and the positioning protrusion 141 is matched with the positioning groove 151 .

[0010] Furthermore, a silicone soft bag is embedded on the outer side of the metal sheet 104 .

[0011] Furthermore, a tongue coating brush is bonded and fixed to the back side of the main brush head 102 .

[0012] Compared with the prior art, the advantages of the present invention are:

[0013] This solution cancels the auxiliary brush head supported by the plastic frame and adopts a metal sheet to support the auxiliary brush head. The auxiliary brush head is plugged and installed at the end of the metal sheet. The insertion depth is adjustable, which makes it easy to adjust the initial spacing of the brush heads and adjust according to user needs. The auxiliary brush head is supported by a metal sheet. The plasticity of the metal sheet is higher than that of plastic. After the bristles are deformed due to long-term use, resulting in an increase in the spacing between the brush heads, the two brush heads can be squeezed inward to further deform the metal sheet, and the spacing between the two brush heads becomes smaller, thereby achieving fine-tuning of the spacing between the brush heads. Secondly, the two brush heads are plugged and installed at the end of the metal sheet. When the degree of wear of the bristles of the auxiliary brush heads is inconsistent, and only one side is severely worn, while the bristles on the other side are in relatively good health, the two brush heads can be removed and swapped, which increases the service life and is more environmentally friendly.

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 7 A multi-head toothbrush includes a brush handle 101 and an auxiliary brush head 103. A main brush head 102 is arranged on the top of the brush handle 101. Bristles 106 are arranged on one side of the auxiliary brush head 103 and the main brush head 102. A socket 105 is opened through the inside of the main brush head 102, and a socket 105 is also opened through the inside of the auxiliary brush head 103. There are two auxiliary brush heads 103. A metal sheet 104 is installed through the inside of the main brush head 102 corresponding to the socket 105. This arrangement makes it easy to install the auxiliary brush head 103.

[0027] See also Figure 1-Figure 6 The two auxiliary brush heads 103 are respectively installed at the two ends of the metal sheet 104 through the sockets 105. This arrangement makes it easy to install and remove the auxiliary brush heads 103 and to adjust the insertion depth of the auxiliary brush heads 103.

[0028] See also Figure 4 The inner wall of one side of the socket 105 is evenly provided with positioning grooves 151, so that the auxiliary brush head 103 can be inserted and installed more stably.

[0029] See also Figure 4-Figure 6 A positioning protrusion 141 is provided at the center and end of one side of the metal sheet 104, and the positioning protrusion 141 is matched with the positioning groove 151. This arrangement makes the auxiliary brush head 103 more stable when plugged in and installed.

[0030] See also Figure 1-Figure 7 A silicone soft bag is embedded on the outer side of the metal sheet 104, so as to reduce the scratching damage to the oral cavity by the metal sheet 104. A tongue coating brush is bonded and fixed on the back side of the main brush head 102, so as to facilitate the cleaning of the tongue coating.

[0031] When in use: first, the user presses the two auxiliary brush heads 103 inwards according to his needs, so that the metal sheet 104 is bent together until the distance between the two auxiliary brush heads 103 is appropriate, and then adjusts the plug-in position of the auxiliary brush head 103, and adjusts the position of the auxiliary brush head 103 nested outside the metal sheet 104 by pulling the auxiliary brush head 103 outwards or squeezing it inwards. After the adjustment is completed, it can be used; when the auxiliary brush head 103 is used for a period of time, one side of it is worn out, such as Figure 8 As shown in FIG. 1 , a wear notch 107 is produced. At this time, the two brush heads 103 are removed and exchanged. Fig. 9 Just shape it.

[0032] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
