[0030] This embodiment provides a digital display mechanism 10, see Figures 1 to 3 , including a circuit board 11, a light guide plate 12 arranged on one side of the circuit board 11, and a display panel 13 arranged on the light guide plate 12. A light emitting element 14 is arranged on the circuit board 11. The light guide plate 12 is mounted on the circuit board 11, and a light guide hole 121 is arranged at the position of the light emitting element 14. The display panel 13 covers the outer side of the light guide hole 121 of the light guide plate 12. The light emitting element 14 on the circuit board 11 is controlled to light up or extinguish by a control center, and the state of the light emitting element 14 is displayed on the display panel 13 through the light guide hole 121 of the light guide plate 12. The structure is simple, the manufacturing cost is low, and the control method is simple.

[0031] There are multiple light-emitting elements 14, and the light-emitting elements 14 are arranged in a set order, and the specific arrangement forms a pattern. The pattern matches the display pattern of the display board 13. The light-emitting elements 14 are LEDs, electric lamp beads, etc. The light-emitting elements 14 are arranged on the circuit board 11 according to the set display pattern, and a single light-emitting element 14 corresponds to a light guide hole 121, so the pattern formed by the arrangement of the light-emitting elements 14 can display the corresponding pattern on the display board 13 when the light-emitting elements 14 themselves are lit or extinguished. The display board 13 is provided with scales, patterns, etc., and the light of the light-emitting elements 14 is projected on different scales, patterns, etc., indicating different functions.

[0032] The light guide plate 12 is arranged to fit the surface of the circuit board 11 to prevent light leakage of the light emitting element 14. Preferably, the contact between the light guide plate 12 and the circuit board 11 is surface contact to improve the sealing of the contact.

[0033] In other embodiments, see Figure 3 , 4A sealing sheet 122 is provided on the surface of the light guide plate 12 that contacts the circuit board 11 , which not only prevents the light emitting element 14 from leaking light, but also prevents the light emitting element 14 from being affected by external dust, water vapor, etc.

[0034] Preferably, the mounting surface of the light guide plate 12 and the circuit board 11 is provided with a mounting groove 123 for mounting a sealing sheet 122. The sealing sheet 122 is disposed in the mounting groove 123, and the sealing sheet 122 protrudes from the mounting surface of the light guide plate 12, so that the sealing sheet 122 can seal the contact between the light guide plate 12 and the circuit board 11.

[0035] The positions where the circuit board 11 contacts the light guide plate 12 or the sealing sheet 122 are all smooth surfaces, so that the light guide plate 12 or the sealing sheet 122 can be in close contact to prevent light leakage.

[0036] For details, please refer to Figure 2 , 3 , a buckle protrusion 124 is provided on the side of the light guide plate 12 facing the circuit board 11. The circuit board 11 is provided with a card slot 111 connected with the buckle protrusion 124. The buckle protrusion 124 of the light guide plate 12 is inserted into the card slot 111 from one side of the circuit board 11, so that the light guide plate 12 is fixedly connected to the circuit board 11. By pressing the buckle protrusion 124 of the light guide plate 12 to the card slot 111 of the circuit board 11, the two can be fixedly connected, the assembly process is simple, and the assembly efficiency can be improved.

[0037] There are multiple light guide holes 121, and the light guide holes 121 correspond to the light emitting elements 14 one by one. One light emitting element 14 corresponds to one light guide hole 121, so that the light of the corresponding light emitting element 14 is projected on the display board 13, so that the light emitting element 14 representing the corresponding function can accurately project the light on the display board 13, avoiding the influence of the adjacent light emitting elements 14. A control module is provided on the circuit board 11, which can control the extinguishing state of the light emitting element 14, and different extinguishing states of the light emitting elements 14 represent different states.

[0038] See also Figures 1 to 3 The display panel 13 is located on the other side of the light guide plate 12 and is provided with a light guide bar 15, and the light guide bar 15 is made of transparent material. The light guide bar 15 is higher than the surface of the display panel 13 and is arranged around the display panel 15, making the display effect of the entire digital display mechanism more three-dimensional.

[0039] Specifically, the light guide plate 12 is provided with a light guide hole 125 at the position where the light guide bar 15 is assembled, and the circuit board 11 is provided with a light emitting element 14 located at the light guide hole 125. Light from the light emitting element 14 can be projected onto the light guide bar 15 through the light guide hole 125.

[0040] Preferably, a light selection cover 16 is provided on the outside of the light guide bar 15, and the light selection cover 16 is evenly distributed with light holes 161. The light selection cover 16 covers the outside of the light guide bar 15, and the light guide bar 15 projects the light of the light emitting element 14 to the light guide bar 15 under the action of the light guide holes 125, and the light guide bar 15 is covered with the light selection cover 16 on the outside, and the light is scattered outward through the light holes 161.

[0041] A nebulizer with a digital display, see Figure 3 , 5 , including an atomizer body 20 and the above-mentioned digital display mechanism 10. The digital display mechanism 10 is arranged on one side of the atomizer body 20, and is used to display the oil level, power level, and working status of the atomizer, so as to facilitate the user to perform human-computer interaction with the atomizer.

[0042] The lighting or extinguishing of the light emitting element 14 on the circuit board 11 is projected onto the display board 13 to represent different states of the atomizer. Therefore, the state of the light emitting element 14 is controlled by the control center and projected onto different scales, patterns and other marks on the display board 13 to show that the atomizer is in different states, which facilitates the human-computer interaction between the user and the atomizer.

[0043] In one embodiment, the display panel 13 is provided with a fuel level display area, a power level display area, and a working mode display area, and corresponding light-emitting elements 14 are provided on the circuit boards of the three corresponding areas. For example, when the remaining fuel level is detected, the light-emitting element 14 corresponding to the fuel level display area is lit, and if the remaining fuel level is half, then half of the corresponding light-emitting elements 14 are lit.

[0044] Compared with the prior art, the present invention projects the light emitting element 14 onto the display board 13 having information such as scales and patterns through the light guide plate 12 arranged on one side of the circuit board 11, which can accurately display the information to be displayed, and has a simple structure and low manufacturing cost. The digital display mechanism 10 is applied to the atomizer to effectively display the use status of the atomizer, facilitate the human-computer interaction between the user and the atomizer, and has a low manufacturing cost, which is convenient for large-scale production.

[0045] The above examples are only used to further illustrate the technical content of the utility model, so that readers can understand it more easily, but it does not mean that the implementation methods of the utility model are limited to this.
