And the inner extension 1132 continues to extend from the soft rubber part 1131 through the inner wall of the display casing 112 to the inner wall of the machine casing 111, so that the contact area between the inner extension part 1132 and the inner wall of the display casing 112 can further be increased, thereby improving the connection stability between the display casing 112 and the machine casing 111.
In addition, combining with the embodiment in which the display casing 112 and the machine casing 111 are integrally molded, the button 113 is integrally molded with the display casing 112 through the soft rubber part 1131 and a part of the inner extension part 1132, the button 113 is also integrally molded with the machine casing 111 through the remaining part of the inner extension part 1132, i.e., the machine casing 111, the display casing 112 and the button 113 are connected to each other through an integrated molding process, and form a structure similar to a triangular connection, thereby improving the stability between the machine casing 111, the display casing 112, and the button 113.

Alternatively, the button 113 may be a mode switching button, when a user presses the button 113, the button 113 transmits a first control signal to the controller to switch the current operating mode of the electric toothbrush 1, and the controller transmits a second control signal to the display screen 141, so that the corresponding light-emitting area 141A on the display screen 141 displays information of the current operating mode, such as text or patterns, the light emitted by the light-emitting area 141A passes through the light-transmitting hole 111B and the display area 112A, and then emits to the outside of the handle housing 11, such that the display area 112A corresponding to the light-emitting area 141A that is displaying content to be in a highlighted state, thereby facilitating users to observe the displayed content through the highlighted display area 112A.
The inner wall surface of the outer casing part 1121 is connected to a connecting part 1123 connected to a hole wall of the light-transmitting hole 111B. The inner casing part 1122 is connected to the connecting part 1123 and passes through the outer circumference side of the light-transmitting hole 111B. The outer casing part 1121, the connecting part 1123, the inner casing part 1122, and the machine casing 111 can integrally be formed through an injection molding process, to increase the connection stability of the outer casing part 1121, the connecting part 1123, the inner casing part 1122, and the machine casing 111.
It may be understood that in some embodiments, when the light-emitting element 14 including a display screen 141, the number of light-transmitting holes 111B is multiple, and the plurality of light-transmitting holes 111B are arranged at intervals along the length direction of the handle housing 11, the number of the light-emitting areas 141A of the display screen 141 are also multiple, and the light-emitting areas 141A correspond to the light-transmitting holes 111B in position by one-to-one correspondence. When a user presses the button 113, the controller controlling the corresponding light-emitting area 141A of the display screen 141 to emit light to illuminate the corresponding light-transmitting holes 111B, thereby highlighting the corresponding display area 112A, so that the user can obtain the display contents of the electric toothbrush 1 through the highlighted display area 112A.

Therefore, in the present disclosure, the display area 112A corresponding to the light-transmitting hole 111B on the display casing 112 is provided to be concave toward the direction of the accommodation cavity 111E, so that the display area 112A is formed into a structure similar to a concave lens, due to the characteristics of the imaging principle of a concave lens, the user can more conveniently observe the upright shrunk virtual image of the full texts or full patterns on the display screen 141 at a larger viewing angle outside the display area 112A, which is more convenient to use. At the same time, in the present disclosure, the light-transmitting hole 111B is disposed in a concave form on the outer wall surface, to make the wall thickness of the light-transmitting hole 111B thinner at least internally, and during the molding and production process of the display casing 112, it can also greatly reduce the shrinkage caused by the larger wall thickness of the light-transmitting hole 111B, and greatly reduce the risk for forming concave pits in the light-transmitting hole 111B, and it can ensure the surface flatness of the light-transmitting hole 111B to have a higher displaying effect, and can also improve the yield of product in a production process.
After the outer wall surface of the display casing 112 in the display area 112A of the present disclosure is configured to be concave toward the direction of the accommodating cavity 111E, the displayed final structural forms are presented in a variety of forms, and the forms are illustrated by the following contents.
As illustrated in
In addition, during actual using processes of the electric toothbrush 1, after the user holds the toothbrush handle, the entire electric toothbrush 1 assuming a tilted posture with a smaller angle between its length direction and the horizontal plane, at this time, the long axis direction of the approximate concave lens structure molded by the display area 112A is also almost horizontal, and the visual field range of the human is usually extended laterally, that is, almost horizontally, so that the two directions are anastomosed, which is more conducive for the user to observe the contents on the display screen 141 and use more conveniently.
Furthermore, the difference between the distance between the outer wall surface of the display casing 112 on either side of the opposite both sides of the display area 112A in the length direction of the machine casing 111 and the display screen 141 and the distance between the outer wall surface of the display casing 112 in the middle part of the display area 112A and the display screen 141 is 0.05 mm to 2 mm (that is, the difference between L1 and L0 is 0.05 mm to 2 mm). The difference between L1 and L0 in this present application can take values of 0.05 mm, 0.06 mm, 0.07 mm . . . 1 mm, 1.01 mm, . . . , 1.5 mm, . . . , 1.99 mm, 2 mm. When the difference is less than 0.05 mm, the positive effect on shrinkage is small and the risk of pits is increased, and when the difference is greater than 2.0 mm, the middle part of the display area 112A is too thin, and its structural strength is smaller and it is easy to break, and the curvature is changed too much, the changes in the contents displayed on the screen observed by the user are inconsistent, so that the display effect is decreased, therefore, this present application is set the difference between L1 and L0 to 0.05 mm to 2 mm. thereby taking into multiple advantages such as good display effect, high production yield, and sufficient structural strength.
It may be understood that the distance between the outer wall of the display casing 112 in the display area 112A and the display screen 141 firstly is decreased from the edge of the display area 112A toward the middle part and then remained unchanged, to make the middle part of the display area 112A relatively flat, and facilitate the form of a concave lens display effect, if the user can more conveniently observe the upright shrunk virtual image of the full texts or full patterns on the display screen 141 at a larger viewing angle outside the display area 121A, which is more convenient to use.
As illustrated in
Furthermore, the difference between the distance L2 between the outer wall surface of the display casing 112 on either side of the opposite both sides of the display area 112A in the left-right direction and the display screen 141, and the distance L0 between the outer wall surface of the display casing 112 in the middle part of the display area 112A and the display screen 141 is 0.05 mm to 1.5 mm (that is, the difference between L2 and L0 is 0.05 mm to 1.5 mm). The difference between L2 and L0 in this present application can be took values of 0.05 mm, 0.06 mm, 0.07 mm . . . 1 mm, 1.01 mm, . . . , 1.3 mm, . . . , 1.49 mm, 1.5 mm. When the difference is less than 0.05 mm, the positive effect on shrinkage is small and the risk of pits is increased, when the difference is greater than 1.5 mm, the middle part of the display area 112A is too thin, and its structural strength is smaller and it is easy to break, and the curvature is changed too much, the changes in the contents displayed on the screen observed by the user are inconsistent, so that the display effect is decreased, therefore, this present application is set the difference between L2 and L0 to 0.05 mm to 1.5 mm. thereby taking into multiple advantages such as good display effect, high production yield, and sufficient structural strength.
It should be noted here that the display area 112A of this present application may be provided individually as follows: the distance between the outer wall surface of the display casing 112 in the display area 112A and the display screen 141 is gradually decreased from the opposite both sides of the display area 112A in the length direction of the machine casing 111 to the middle part, and also may be provided individually as follows: the distance between the outer wall surface of the display casing 112 in the display area 112A and the display screen 141 is gradually decreased from the opposite both sides of the display area 112A in the left-right direction to the middle part, or both of the above disposing forms exist at the same time.
As illustrated in
Furthermore, when the display area 112A is circular, the wall thickness of the display area 112A is gradually decreased from the outer circle of the circle to the middle part. With this arrangement, the outer wall surface of the display casing 112 in the display area 112A is smoothly recessed toward the middle part, so that the structure of the display area 112A is closer to the structure of a concave lens, based on obtaining better display effects, the stress generated everywhere during the production and molding process may be relatively balanced, concave pits on the surface of the display area due to the shrinkage are not easily generated, thus improving the yield of product.
It may be understood that when the display area 112A is circular, the wall thickness of the display area 112A firstly is decreased from the circular outer circle to the middle part and then then remained unchanged, to make the middle part of the display area 112A relatively flat, and facilitate the form of a concave lens display effect, so that the user can conveniently observe the upright shrunk virtual image of the full texts or full patterns on the display screen 141, which is more convenient to use.
Based on the above contents, it may be understood that this present application is used the concave of the outer wall surface of the display casing 112 in the display area 112A to form an approximate concave lens structure, so that the user obtains a larger visual field range, and uses the characteristics of the concave lens to form an upright shrunk virtual image. When the size of the display screen 141 is larger, the full patterns or full texts on the display screen 141 can also be displayed through the display area 112A.
Based on the above, the present application further limits the area enclosed by the outer contour of the display area 112A to less than 6 square centimeters. In this way, when the whole electric toothbrush 1 tends to be miniaturized and designed to be easier to hold, the surface area of the toothbrush handle occupied by the entire display area 112A will not be too large, so that the display area 112A is much more uniform visually in terms of visual effects, thereby improving the structural consistency of the handle housing 11, ensuring that it has a high structural strength, and can also reduce the cost accordingly.
