DETAILED DESCRIPTION

[0082] In order to make the purpose, technical solution and advantages of this application more clear, the following is a further detailed description of this application in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain this application and do not limit the scope of protection of this application.

[0083] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0084] In recent years, as people's living standards continue to improve, they pay more and more attention to their health and appearance. Among them, the health and beauty of teeth are particularly important to people. People usually use orthodontic products to correct their teeth to ensure the health of teeth and improve the beauty of teeth. At present, there are many types and brands of orthodontic products, which makes it possible for consumers to choose from many orthodontic products. How to attract consumers and improve product competitiveness has become an issue that orthodontic bracket manufacturers pay more and more attention to.

[0085] In the related art, in order to promote orthodontic products, the following methods are usually used for promotion and publicity. First, traditional posters or leaflets are used. The advantages are low cost and can be printed in large quantities, but printed materials can only display products in a flat manner, and cannot display the characteristics of the products in a three-dimensional and all-round manner. The promotional effect is poor and difficult to feel intuitively. Second, dental molds are used. The advantages are simulation and three-dimensional, and can display the characteristics of the products in an all-round manner. The promotional effect is good and can be felt intuitively, but the production cost is high, it is inconvenient to carry, and it cannot be produced or distributed in large quantities.

[0086] Based on this, the present disclosure provides a comparison device 10, which can display the state of teeth without wearing orthodontic appliances 20 and the state of teeth wearing different types of orthodontic appliances 20, so that consumers can intuitively feel the difference between teeth before and after wearing orthodontic appliances 20, as well as the state of teeth wearing different types of orthodontic appliances 20. The comparison device 10 has a good publicity effect, a low production cost, and is easy to carry.

[0087] In the embodiments of the present disclosure, Figures 1 to 3 As shown, the comparison device 10 includes a housing component 100 and a plurality of display pieces 200. The housing component 100 is provided with at least one display window and a receiving cavity 110 connected to the at least one display window, and the at least one display window includes a first display window 120. The plurality of display pieces 200 are arranged in the receiving cavity 110 and can be displayed in the first display window 120. At least one display piece 200 is movably arranged in the receiving cavity 110 and cooperates with other display pieces 200 to form a plurality of display states in the first display window 120. The plurality of display states include at least two of a first display state, a second display state and a third display state. The first display state includes displaying a state of teeth wearing a first orthodontic appliance 20. The second display state includes displaying a state of teeth wearing a second orthodontic appliance 20 different from the first orthodontic appliance 20. The third display state includes a state of teeth not wearing an orthodontic appliance 20. Each display state is displayed by one display piece 200 among the plurality of display pieces or a combination of at least two display pieces 200.

[0088] In this way, by setting a plurality of display pieces 200 in the accommodating cavity 110 of the housing assembly 100 and being able to display them in the first display window 120 of the housing assembly 100, the comparison device 10 can display different tooth states. When the comparison device 10 is displayed, at least one display piece 200 is movably arranged in the housing assembly 100, and cooperates with other display pieces 200 to form a plurality of display states in the first display window 120. Moreover, each display state is a display of one display piece 200 among a plurality of display pieces or a combination of at least two display pieces 200. The plurality of display states include at least two of a first display state, a second display state, and a third display state. The first display state includes displaying a tooth state of wearing a first orthodontic appliance 20. The second display state includes displaying a tooth state of wearing a second orthodontic appliance 20 different from the first orthodontic appliance 20. The third display state includes a tooth state of not wearing an orthodontic appliance 20. When the comparison device 10 is in the first display state or the second display state, the first display window 120 can display one display piece 200 among the multiple display pieces 200, or display a combination of at least two display pieces 200. When the comparison device 10 is in the third display state, the first display window 120 can display another display piece 200 among the multiple display pieces 200, or display a combination of at least two other display pieces. The comparison device 10 can display the state of teeth without wearing orthodontic appliances 20 and the state of teeth wearing different types of orthodontic appliances 20. Consumers can intuitively feel the difference between teeth before and after wearing orthodontic appliances 20, as well as the state of teeth wearing different types of orthodontic appliances 20. The comparison device 10 has a good publicity effect, can attract consumers to buy orthodontic appliances 20, and has a low production cost and is easy to carry.

[0089] It should be noted that there are many specific implementations of the display piece 200 being movably disposed on the housing assembly 100, including the display piece 200 being slidably disposed on the housing assembly 100, the display piece 200 being rotatably disposed on the housing assembly 100, etc. It is sufficient that multiple display pieces 200 can be formed in multiple display states in the first display window 120.

[0090] like Figure 4As shown, in one embodiment, the housing assembly 100 includes a carrier 130 and a display body 140 provided with a display window, at least a portion of the carrier 130 is arranged opposite to the display body 140, and the display body 140 cooperates with the carrier 130 to form at least a portion of the accommodating cavity 110. A plurality of display pieces 200 are sandwiched between the display body 140 and the carrier 130. In this way, the housing assembly 100 is arranged opposite to at least a portion of the carrier 130 and the display body 140, and cooperates with each other to form at least a portion of the accommodating cavity 110. A plurality of display pieces 200 are sandwiched between the display body 140 and the carrier 130. The display piece 200 can move between the display body 140 and the carrier 130, and be displayed in the display window to form a variety of display states. The comparison device 10 can display the state of the teeth without wearing the orthodontic appliance 20 and display the state of the teeth wearing different orthodontic appliances 20.

[0091] It should be noted that there are many specific implementation methods for the shell assembly 100, including directly forming the shell assembly 100 by integral molding, forming the shell assembly 100 by integral molding and then folding, or forming the shell assembly 100 by bonding the carrier 130 and the display body 140, etc.

[0092] like Figures 1 to 3As shown, in one embodiment, the plurality of display pieces 200 include at least two of a first display piece 210, a second display piece 220, and a third display piece 230. The first display piece 210 includes a first display surface 211 for displaying the state of teeth wearing the first orthodontic appliance 20, the second display piece 220 includes a second display surface 221 for displaying the state of teeth wearing the second orthodontic appliance 20, and the third display piece 230 includes a third display surface 231 for displaying the state of teeth without wearing the orthodontic appliance 20. At least one of the first display piece 210, the second display piece 220, and the third display piece 230 is movably disposed between the display body 140 and the carrier body 130. When the comparison device 10 is in the first display state, the first display window 120 can display the first display surface 211. When the comparison device 10 is in the second display state, the first display window 120 can display the second display surface 221. When the comparison device 10 is in the third display state, the first display window 120 can display the third display surface 231. Thus, the first display piece 210 is provided with a first display surface 211 capable of displaying the state of teeth wearing the first orthodontic appliance 20, the second display piece 220 is provided with a second display surface 221 capable of displaying the state of teeth wearing the second orthodontic appliance 20, and the third display piece 230 is provided with a third display surface 231 capable of displaying the state of teeth not wearing the orthodontic appliance 20. When the comparison device 10 is displayed, the first display state, the second display state and the third display state can be displayed. Thus, consumers can intuitively feel the difference between teeth not wearing orthodontic appliances 20 and teeth wearing orthodontic appliances 20, and can also clearly understand the state of teeth wearing different types of orthodontic appliances 20, so that consumers can better choose the type of orthodontic appliances 20 they like.

[0093] It should be noted that there may be many specific implementations of the first orthodontic appliance 20 and the second orthodontic appliance 20. For example, the styles of the orthodontic appliance 20 may include metal orthodontic appliances, ceramic orthodontic appliances, and the like.

[0094] Furthermore, if Figure 5 as well as Figure 6 As shown, in one embodiment, the comparison device 10 includes a first display piece 210 and a second display piece 220, so that the comparison device 10 has a first display state and a second display state. In this way, the comparison device 10 can display the state of teeth wearing the first orthodontic appliance 20 and the second orthodontic appliance 20, and consumers can intuitively compare the difference between wearing different orthodontic appliances 20, so that consumers can better choose the type of orthodontic appliance 20 they like.

[0095] like Figure 7 as well as Figure 8As shown, in some embodiments, the first display piece 210 is fixed to the carrier 130, and the second display piece 220 is movably disposed between the first display piece 210 and the display body 140. When the comparison device 10 is in the first display state, the second display piece 220 avoids the first display surface 211, so that the first display surface 211 is displayed in the first display window 120. When the comparison device 10 is in the second display state, the second display piece 220 shields the first display surface 211, so that the second display surface 221 is displayed in the first display window 120. In this way, when the comparison device 10 is displayed, the second display piece 220 moves between the first display piece 210 and the display body 140, so that the comparison device 10 is in the first display state and the second display state respectively. This display method is easy to operate, and the comparison device 10 using this display method is easy to manufacture.

[0096] Specifically, there are many specific implementation methods for fixing the first display piece 210 to the carrier 130, for example, the first display piece 210 is fixed to the carrier 130 by bonding. For another example, in one embodiment, the first display piece 210 and the carrier 130 are integrally formed. In this way, the connection reliability between the first display piece 210 and the carrier 130 can be ensured, and the integrally formed manufacturing method can reduce the production steps and save production costs.

[0097] Furthermore, there are many specific implementations of the second display element 220 being movably disposed between the first display element 210 (ie, the carrier 130 ) and the display body 140 .

[0098] In one embodiment, if Figure 7 as well as Figure 8 As shown, the second display element 220 is slidably connected to the carrier 130 and the display body 140 .

[0099] In another embodiment, the second display element 220 is rotatably connected to the carrier 130 and the display body 140. In this way, the sliding connection or the rotatable connection can further facilitate consumers to switch the display state of the comparison device 10, thereby improving the consumer's use experience.

[0100] It can be understood that as long as the second display element 220 can be movably disposed between the carrier 130 and the display body 140 , other achievable methods will not be listed here.

[0101] In some embodiments, Figure 5 as well as Figure 6As shown, the first display piece 210 and the second display piece 220 are movably disposed between the carrier 130 and the display body 140, respectively. When the comparison device 10 is in the first display state, the second display surface 221 avoids the first display window 120, so that the first display surface 211 is displayed in the first display window 120. When the comparison device 10 is in the second display state, the second display piece 220 shields the first display surface 211 or the first display surface 211 avoids the first display window 120, so that the second display surface 221 is displayed in the first display window 120. In this way, when the comparison device 10 is displayed, the first display piece 210 and the second display piece 220 can move between the carrier 130 and the display body 140, respectively. When in the first display state, the second display piece 220 moves so that the second display surface 221 avoids the first display window 120, and the first display piece 210 moves so that the first display surface 211 can be displayed in the first display window 120. When in the second display state, the second display member 220 moves to cover the first display surface 211 so that the second display surface 221 is displayed in the first display window 120. Or in other embodiments, the first display member 210 moves so that the first display surface 211 avoids the first display window 120, so that the second display surface 221 can be displayed in the first display window 120. The comparison device 10 is thus in the second display state. This display method is also easy to operate, and the comparison device 10 using this display method is easy to manufacture.

[0102] Further, in one embodiment, the first display piece 210 is movably connected to the second display piece 220, and at least one of the first display piece 210 and the second display piece 220 is movably connected to the housing assembly 100. Thus, for example, the movably connected at least one of the first display piece 210 and the second display piece 220 to the housing assembly 100 may be the movably connected first display piece 210 to the housing assembly 100. When the comparison device 10 is displayed, the first display piece 210 is movably connected to the housing assembly 100, and the first display piece 210 is movably connected to the second display piece 220. When the comparison device 10 is in the first display state, the first display piece 210 is movable in the housing assembly 100, and the first display piece 210 shields the second display piece 220, so that the first display surface 211 can be displayed in the first display window 120. When in the second display state, the first display piece 210 moves in the housing assembly 100, and the first display surface 211 avoids the first display window 120, so that the second display surface 221 of the second display piece 220 is displayed in the first display window 120. Thus, the comparison device 10 can display the first display state or the second display state. This display method is also easy to operate, and the comparison device 10 using this display method is easy to manufacture.

[0103] Of course, it can be understood that at least one of the first display piece 210 and the second display piece 220 is movably connected to the shell assembly 100 also includes the second display piece 220 being movably connected to the shell assembly 100, and the first display piece 210 and the second display piece 220 are both movably connected to the shell assembly 100.

[0104] The above describes a case where the comparison device 10 includes a first display piece 210 and a second display piece 220, and has a first display state and a second display state. Of course, the comparison device 10 may also include a first display piece 210 and a third display piece 230, so as to have a first display state and a second display state. It may also include a second display piece 220 and a third display piece 230, so as to have a second display state and a second display state. It may also include a first display piece 210, a second display piece 220 and a third display piece 230, so as to have a first display state, a second display state and a second display state. Other embodiments will be described below.

[0105] like Figures 1 to 3 As shown, in one embodiment, the comparison device 10 further includes a third display piece 230, so that the comparison device 10 also has a third display state. In this way, the comparison device 10 can display the tooth state when wearing the first orthodontic appliance 20, the second orthodontic appliance 20, and not wearing the orthodontic appliance 20, and consumers can intuitively see the tooth state when wearing the orthodontic appliance 20 and not wearing the orthodontic appliance 20, as well as the tooth state when wearing different orthodontic appliances 20, thereby improving the publicity effect of the orthodontic appliance 20, thereby attracting consumers to wear the orthodontic appliance 20 and enabling consumers to better choose the type of orthodontic appliance 20 they like.

[0106] Further, in some embodiments, the third display element 230 is fixed to the carrier 130. When the comparison device 10 is in the first display state, the first display element 210 shields the third display surface 231, so that the first display surface 211 is displayed in the first display window 120. When the comparison device 10 is in the second display state, the second display element 220 shields the third display surface 231, so that the second display surface 221 is displayed in the first display window 120. When the comparison device 10 is in the third display state, the first display element 210 and the second display element 220 avoid the third display surface 231, so that the third display surface 231 is displayed in the first display window 120. In this way, when the comparison device 10 displays the first display state, the second display state and the third display state, the display method is easy to operate, and the comparison device 10 using the display method is easy to manufacture.

[0107] like Fig. 9 as well as Fig.10As shown, in one embodiment, the comparison device 10 includes a first display piece 210 and a third display piece 230, so that the comparison device 10 has a first display state and a third display state. In this way, the comparison device 10 can display the state of teeth with and without the first orthodontic appliance 20, and consumers can intuitively see the state of teeth with and without the orthodontic appliance 20, thereby improving the publicity effect of the orthodontic appliance 20 and attracting consumers to wear the orthodontic appliance 20.

[0108] like Fig. 9 as well as Fig.10 As shown, in some embodiments, the third display element 230 is fixed to the carrier 130, and the first display element 210 is movably disposed between the third display element 230 and the display body 140. When the comparison device 10 is in the first display state, the first display element 210 shields the third display surface 231, so that the first display surface 211 is displayed in the first display window 120. When the comparison device 10 is in the third display state, the first display element 210 avoids the third display surface 231, so that the third display surface 231 is displayed in the first display window 120.

[0109] It should be noted that the specific implementation method of fixing the third display element 230 to the carrier 130 may be the same as the method of fixing the first display element 210 to the carrier 130 , which will not be further elaborated herein.

[0110] Specifically, in one embodiment, the third display element 230 and the carrier 130 are integrally formed.

[0111] Based on the above embodiment in which the third display element 230 and the carrier 130 are integrally formed, in one embodiment, the first display element 210 is slidably connected to the carrier 130 and the display body 140. Alternatively, in another embodiment, the first display element 210 is rotatably connected to the carrier 130 and the display body 140.

[0112] It should be noted that the specific implementation method of movably disposing the first display element 210 between the carrier 130 and the display element 140 may be the same as the method of movably disposing the second display element 220 between the carrier 130 and the display element 140, which will not be further elaborated here.

[0113] In one embodiment, the first display element 210 and the third display element 230 are movably disposed between the carrier 130 and the display body 140. When the contrast device 10 is in the first display state, the third display surface 231 avoids the first display window 120, so that the first display surface 211 is displayed in the first display window 120. When the contrast device 10 is in the third display state, the third display element 230 shields the first display surface 211 or the first display surface 211 avoids the first display window 120, so that the third display surface 231 is displayed in the first display window 120.

[0114] It can be understood that the comparison device 10 includes the first display piece 210 and the third display piece 230, and the implementation method of having the first display state and the third display state can be the same as the implementation method of the comparison device 10 including the first display piece 210 and the second display piece 220, and having the first display state and the second display state. Of course, the comparison device 10 includes the second display piece 220 and the third display piece 230, and has the second display state and the second display state. Or the comparison device 10 includes the first display piece 210, the second display piece 220 and the third display piece 230, and has the first display state, the second display state and the second display state can also be implemented in the above manner, and no further elaboration is made here.

[0115] Of course, there are many other specific implementations of the display of the comparison device 10. For example, a plurality of different display states may be displayed by superposition.

[0116] like Figures 11 to 13As shown, in one embodiment, the plurality of display pieces 200 include a fourth display piece 240, the fourth display piece 240 includes a fourth display surface 241 of the state of the teeth without wearing the orthodontic appliance 20, the plurality of display pieces 200 include at least one of a fifth display piece 250 and a sixth display piece 260, the fifth display piece 250 includes a fifth display surface 251 displaying the first orthodontic appliance 20, the sixth display piece 260 includes a sixth display surface 261 displaying the second orthodontic appliance 20, and the fifth display piece 250 and the sixth display piece 260 are movably arranged between the display body 140 and the carrier body 130. When the comparison device 10 is in the first display state, the first display window 120 can display the fifth display surface 251 superimposed on the fourth display surface 241. When the comparison device 10 is in the second display state, the first display window 120 can display the sixth display surface 261 superimposed on the fourth display surface 241. When the comparison device 10 is in the third display state, the first display window 120 can display the fourth display surface 241. In this way, the fifth display surface 251 or the sixth display surface 261 is superimposed on the fourth display surface 241, so that the comparison device 10 is in the first display state or the second display state. When the first display window 120 displays the fourth display surface 241, the comparison device 10 is in the third display state. In this way, by superimposing the display surfaces, the fifth display surface 251 and the sixth display surface 261 can only be provided with the orthodontic appliance 20 without the tooth model. Thereby reducing the manufacturing cost of the display piece 200.

[0117] Furthermore, the orthodontic appliance 20 in the fifth display surface 251 displaying the first orthodontic appliance 20 and the sixth display surface 261 displaying the orthodontic appliance 20 worn by the user may be in a three-dimensional shape. In this way, the orthodontic appliance 20 can be displayed more vividly, and consumers can directly feel the structure of the orthodontic appliance 20, thereby improving the publicity effect.

[0118] like Figures 11 to 13As shown, in some embodiments, the fourth display element 240 is fixed to the carrier 130, and the fifth display element 250 and the sixth display element 260 are respectively movably disposed between the fourth display element 240 and the display body 140. When the comparison device 10 is in the first display state, at least a portion of the fifth display element 250 is disposed on the fourth display surface 241, so that the fifth display surface 251 is superimposed on the fourth display surface 241 and displayed in the first display window 120. When the comparison device 10 is in the second display state, at least a portion of the sixth display element 260 is disposed on the fourth display surface 241, so that the sixth display surface 261 is superimposed on the fourth display surface 241 and displayed in the first display window 120. When the comparison device 10 is in the third display state, the fifth display element 250 and the sixth display element 260 avoid the fourth display surface 241, so that the fourth display surface 241 is displayed in the first display window 120. This display method is easy to operate, and the comparison device 10 using this display method can reduce the manufacturing cost.

[0119] Of course, there are many other specific implementations of the display of the comparison device 10. For example, it can also display a variety of different display states by rotating.

[0120] In one embodiment, the comparison device 10 further includes a rotating assembly 300, which can be rotatably disposed on the housing assembly 100. The first display piece 210 and the second display piece 220 are sequentially wound around the rotating assembly 300, and switch between the first display state and the second display state as the rotating assembly 300 rotates. In this way, by sequentially winding the first display piece 210 and the second display piece 220 around the rotating assembly 300, and when the rotating assembly 300 rotates, the first display piece 210 and the second display piece 220 can be displayed in the first display window 120. Thus, switching between the first display state and the second display state is achieved. This display method is also easy to operate and can save space, so that the comparison device 10 can be designed in a miniaturized manner to improve the user experience of consumers.
