According to this configuration, it is assumed that the posture of the electric toothbrush 10 is maintained in a state where the longitudinal axis of the electric toothbrush 10 is inclined with respect to the longitudinal axis of the toothbrush stand 100 (hereinafter, “first virtual set”). ) And the following effects. Since the electric toothbrush 10 is inclined with respect to the toothbrush stand 100, the first virtual set has a larger width dimension. On the other hand, since the axis of the electric toothbrush 10 and the axis of the toothbrush stand 100 are parallel or coincide with each other, the oral care set 1 of the present embodiment can be made smaller in width than the first virtual set. Further, in the first brush holding state, the electric toothbrush 10 stands upright with respect to the installation surface of the toothbrush stand 100. For this reason, the beauty of the oral care set 1 when the electric toothbrush 10 is held by the toothbrush stand 100 is improved.

  The electric toothbrush 10 is allowed to move in the width direction with respect to the toothbrush stand 100 within a minute clearance formed between the intermediate case 40 and the stand main body 110 in the first brush holding state. Is done. For this reason, the relationship between the axis of the toothbrush stand 100 and the axis of the electric toothbrush 10 includes a relationship that coincides with each other and a relationship that is parallel to each other. When the oral care set 1 is in a state in which the respective axes are parallel in the first brush holding state, the outer appearance in a state in which the respective axes coincide with each other regardless of the position in the width direction of the electric toothbrush 10 with respect to the toothbrush stand 100. And an appearance that is not substantially different from that.

  (3) The toothbrush stand 100 includes a stand main body portion 110 and a stand support portion 400. The stand main body portion 110 has a stand opening portion 200. The stand opening portion 200 has an opening internal space 204 into which the toothbrush attachment 80 is inserted. The stand support part 400 is formed on the lower side ZB2 side of the stand body part 110 in the longitudinal direction of the toothbrush stand 100 and supports the stand body part 110. According to this structure, compared with the structure assumed that the stand support part 400 does not exist, the contact area of the toothbrush stand 100 and an installation surface becomes large. For this reason, when the electric toothbrush 10 is inserted into the toothbrush stand 100 and when the electric toothbrush 10 is extracted from the toothbrush stand 100, the toothbrush stand 100 is not easily tilted even if the electric toothbrush 10 contacts the toothbrush stand 100. For this reason, when the oral care set 1 is used, the toothbrush stand 100 is not easily tilted and falls.

  (4) The electric toothbrush 10 has a decorative ring 70. The decorative ring 70 has a shape protruding outward in the width direction from the toothbrush attachment 80. The stand opening portion 200 has an opening portion end face 203 at the upper end portion in the longitudinal direction of the toothbrush stand 100. The toothbrush stand 100 maintains the posture of the electric toothbrush 10 by contacting the decorative ring 70 at the opening portion end surface 203. That is, the decorative ring 70 is selected as a portion supported by the toothbrush stand 100 in the electric toothbrush 10. According to this configuration, restrictions on the design of the shape of the toothbrush main body 20 are reduced as compared with the configuration assumed that the portion supported by the toothbrush stand 100 is formed on the toothbrush main body 20. For this reason, it becomes possible to form the toothbrush main body 20 having a shape that is easily gripped by the user as compared with the assumed configuration.

  (5) The toothbrush stand 100 has a configuration capable of inserting the toothbrush body 20 of the electric toothbrush 10 into the stand body portion 110. According to this configuration, the electric toothbrush 10 can be held in a state where the toothbrush attachment 80 is located outside the toothbrush stand 100. That is, the toothbrush stand 100 can hold the electric toothbrush 10 in both the first brush holding state and the second brush holding state. For this reason, the user can select both the first brush holding state and the second brush holding state when the oral care set 1 is used. For this reason, compared with the structure assumed that the 2nd brush holding state cannot be selected, a user's usability improves.

  (6) When the toothbrush stand 100 holds the electric toothbrush 10 in the first brush holding state, a space is formed between the brush tip portion 80A and the bottom wall portion main surface 412. According to this configuration, the moisture on the bottom wall portion main surface 412 adheres to the brush head 82 as compared with the configuration in which the brush tip portion 80A is in contact with the bottom wall portion main surface 412 in the first brush holding state. Hateful. For this reason, it becomes possible to keep the electric toothbrush 10 in a cleaner state.

  (7) The toothbrush stand 100 includes a stand main body portion 110 and a stand support portion 400. The stand support portion 400 is formed on the lower side ZB2 side of the stand body portion 110 in the longitudinal direction of the toothbrush stand 100, and supports the stand body portion 110. The stand support portion 400 has a width dimension larger than that of the stand main body portion 110. According to this configuration, the following effects can be obtained as compared with the configuration (hereinafter, “second virtual set”) in which the stand support portion 400 is assumed to be thinner than the stand main body portion 110. In the second virtual set, since the stand support portion 400 is thinner than the stand main body portion 110, the contact area between the toothbrush stand 100 and the installation surface may not be sufficiently secured. For this reason, when the electric toothbrush 10 is inserted into the toothbrush stand 100 and when the electric toothbrush 10 is extracted from the toothbrush stand 100, there is a high possibility that the toothbrush stand 100 is inclined due to the contact of the electric toothbrush 10 with the toothbrush stand 100. On the other hand, in the oral care set 1, the width dimension of the stand support part 400 is larger than the width dimension of the stand main body part 110, so that the toothbrush stand 100 is tilted when the oral care set 1 is used compared to the second virtual set. In addition, it is hard to fall.

  (8) The stand main body portion 110 has a stand opening portion 200 and a stand intermediate portion 300. The stand intermediate portion 300 is formed between the stand opening portion 200 and the stand support portion 400 in the longitudinal direction of the toothbrush stand 100 and has a shape covering the toothbrush attachment 80. According to this configuration, when the electric toothbrush 10 is held in the first brush holding state, the portion of the toothbrush attachment 80 excluding the portion facing the vent hole 360 is covered with the stand intermediate portion 300. For this reason, since most of the brush head 82 is not visually recognized in the external appearance of the oral care set 1, the beauty of the oral care set 1 is improved. Further, it becomes difficult for foreign matters such as dust to adhere to the brush head 82.

  (9) The stand intermediate portion 300 has an intermediate internal space 301 and a vent hole 360. The intermediate internal space 301 is formed continuously with the opening internal space 204. The vent 360 communicates the intermediate internal space 301 with the outside. According to this configuration, since external air flows into the stand internal space 101 through the vent hole 360, the toothbrush attachment 80 is easily dried as compared with a configuration in which the vent hole 360 is not formed.

  (10) The toothbrush stand 100 has a configuration capable of combining the stand main body portion 110 and the stand support portion 400 with each other and separating the stand main body portion 110 and the stand support portion 400 from each other. According to this configuration, it is possible to clean the respective parts in a state where the stand main body portion 110 and the stand support portion 400 are separated from each other. For this reason, the inside of the toothbrush stand 100 can be easily cleaned.

  (11) The stand support portion 400 includes a support bottom wall portion 410 that faces the toothbrush attachment 80 in the longitudinal direction of the toothbrush stand 100. According to this configuration, moisture dripped from the electric toothbrush 10 due to gravity is received by the bottom wall portion main surface 412 of the support bottom wall portion 410. For this reason, compared with the structure assumed that the support bottom wall part 410 is not formed in the stand support part 400, the quantity of the water | moisture content adhering to the installation surface of the toothbrush stand 100 decreases.

  (12) The stand support portion 400 has a drainage channel 440 in the support peripheral wall portion 420. According to this configuration, moisture on the bottom wall portion main surface 412 flows to the outside of the stand support portion 400 through the drainage channel 440. For this reason, accumulation of a large amount of moisture on the bottom wall portion main surface 412 is suppressed.

  (13) The supporting bottom wall portion 410 has a bottom wall portion main surface 412 facing the toothbrush attachment 80. The bottom wall portion main surface 412 is inclined from the upper side ZA2 side in the longitudinal direction of the toothbrush stand 100 toward the lower side ZB2 side with distance from the axis of the stand support portion 400 in the width direction of the toothbrush stand 100. According to this configuration, since the moisture of the bottom wall portion main surface 412 flows toward the drainage channel 440, the effect of suppressing a large amount of moisture from being accumulated on the bottom wall portion main surface 412 is enhanced.

  (14) The width dimension of the stand intermediate portion 300 is the largest on the outer wall portion end surface 313 as the main body maximum width portion. The width dimension of the stand support portion 400 is the largest at the bottom wall portion bottom surface 413 as the maximum support width portion. The width dimension of the bottom wall portion bottom surface 413 is larger than the width dimension of the outer wall portion end surface 313. According to this configuration, the contact area between the installation surface of the toothbrush stand 100 and the bottom wall portion bottom surface 413 is compared with the configuration in which the width dimension of the stand intermediate portion 300 is assumed to be larger than the width dimension of the bottom wall portion bottom surface 413. Becomes larger. For this reason, when the oral care set 1 is used, the toothbrush stand 100 is less likely to tilt and fall.

  (15) The width dimension of the bottom wall portion bottom surface 413 is 1.5 times or more the width dimension of the outer wall portion end surface 313. By selecting this width dimension relationship, the inventor of the present application makes it difficult for the toothbrush stand 100 to tilt when the oral care set 1 is used, as compared with a configuration in which a relationship different from this width dimension relationship is selected. It was confirmed. For this reason, when the oral care set 1 is used, the toothbrush stand 100 is not easily tilted and falls.

  (16) The width dimension of the toothbrush stand 100 gradually increases from the opening portion end surface 203 toward the outer wall portion end surface 313 in the longitudinal direction. The width dimension of the toothbrush stand 100 gradually increases in the longitudinal direction from the peripheral wall portion end surface 423 toward the bottom wall portion bottom surface 413. The width dimension of the toothbrush stand 100 is gradually increased from the opening part end face 203 toward the bottom wall part bottom face 413 when a change in the longitudinal direction is described except for the fitting connection part 350. According to this configuration, since the toothbrush stand 100 has a tapered shape in which the width dimension becomes smaller as it goes toward the upward direction ZA2 in the longitudinal direction, the toothbrush stand 100 is less likely to be inclined and toppled when the oral care set 1 is used. . Moreover, the aesthetics of the oral care set 1 in a 1st brush holding state improve by having a taper shape as the oral care set 1 goes to the upward direction ZA side of a longitudinal direction.

  (17) The stand support portion 400 includes a support bottom wall portion 410 having a solid structure. According to this configuration, since the weight of the portion on the lower direction ZB2 side in the longitudinal direction of the toothbrush stand 100 is relatively large, the toothbrush stand 100 is not easily tilted or overturned when the oral care set 1 is used.

  (18) In the stand support portion 400, the thickness of the stand support portion 400 defined by the distance from the bottom wall portion bottom surface 413 to the bottom wall portion main surface 412 is larger than the thickness of the intermediate outer wall portion 310 of the stand main body portion 110. . According to this configuration, the weight of the stand support portion 400 is increased compared to the configuration in which the thickness of the stand support portion 400 is assumed to be smaller than the thickness of the intermediate outer wall portion 310. For this reason, the effect which suppresses the inclination and fall of the toothbrush stand 100 at the time of use of the oral care set 1 becomes high.
