Description

Technical Field

[0001] The utility model relates to a liquid vaporizer with an indicator light. Background Art

[0002] Traditional liquid vaporizers, such as electric mosquito repellent devices or electric aromatherapy devices, generally include a base shell and a liquid bottle detachably connected to the base shell. A heater is provided on the base shell, which can heat the liquid to improve the evaporation effect of the liquid, and thus achieve functions such as mosquito repellent and aromatherapy.

[0003] Indicator lights are generally provided on existing liquid vaporizers to facilitate users to intuitively understand the working state of the liquid vaporizer. Of course, they can also be used as decorative lights. On conventional liquid vaporizer products, the indicator lights are usually lamp beads embedded in the base shell, presenting a small bright spot from the external visual effect, and the visual effect is not beautiful enough. And these lamp beads are usually powered and connected through wires, and the assembly is rather troublesome. Of course, there are also some lamp beads directly welded to the same circuit board as the button. The lamp beads are powered through the circuit board and relatively fixed to the base shell, but this structure has certain limitations on the installation position of the lamp beads, and the indicator lights can usually only be configured at positions close to the button. Summary of the Utility Model

[0004] In order to overcome the defects of the above-mentioned prior art, the utility model provides a liquid vaporizer with an indicator light, which solves the problems of poor visual effect, complex assembly structure and limited installation position of the indicator light of the existing liquid vaporizer.

[0005] The liquid vaporizer with an indicator light of the utility model includes a base shell. A circuit board is arranged inside the base shell, and the circuit board is fixedly connected and cooperated with the base shell. A light-emitting element is welded and fixed on the circuit board, and the circuit board powers the light-emitting element, avoiding the problems of inconvenient wiring caused by wire connection and the need for the light-emitting element to be fixed to the base shell. A first mounting hole is provided on the base shell. A light guide member is arranged inside the base shell. The light guide member is preferably transparent. One end of the light guide member is inserted at the first mounting hole, and the other end of the light guide member is arranged at a position corresponding to the circuit board and in the light emission direction of the light-emitting element. The light guide member is made of a light guide material. The other end of the light guide member includes a light receiving surface for receiving light, and this light receiving surface is inclined. The inclined light receiving surface can guide the received light towards one end of the light guide member, so that the light penetrates outwards from the first mounting hole at one end of the light guide member.

[0006] Furthermore, a second mounting hole is provided in the middle of the front side wall of the base housing. A button is movably arranged at the second mounting hole. The circuit board is arranged behind the second mounting hole. A switch element linked with the button is fixedly soldered on the front side of the circuit board. The light-emitting element is soldered on the front side of the circuit board. Soldering the switch element and the light-emitting element on the same circuit board is beneficial to reducing the number of components inside the base housing and facilitating the simultaneous installation of the switch element, the light-emitting element, and the circuit board. The other end of the light guide is arranged at a position between the rear of the front side wall of the base housing and the circuit board. The first mounting hole is arranged at the upper end, lower end, or both sides of the base housing, making the internal structure of the base housing more compact.

[0007] Furthermore, a limiting block is arranged at the light guide near one of its ends. The limiting block is in cooperation with the inner side of the base housing for limiting, and is used to prevent the light guide from moving towards the outer side of the first mounting hole. Lugs are arranged on both sides of the light guide, and positioning holes are arranged on the lugs. The base housing includes two positioning posts that are in plug-in positioning cooperation with the positioning holes of the lugs. The plug-in of the positioning posts and the positioning holes and the plug-in of the first mounting hole and the light guide are in the same linear direction. The installation structure is simple, facilitating the assembly connection between the light guide and the base housing.

[0008] Furthermore, both the light guide and the first mounting hole are in a flat shape. The flat-shaped light guide reduces the occupation of the internal space of the base housing, and the cooperation with the flat-shaped first mounting hole can achieve a strip-shaped indicator light visual effect.

[0009] Furthermore, the other end of the light guide includes a notch. The receiving surface constitutes the bottom inner wall of the notch. The notch also has two side walls that are oppositely arranged and connected to both sides of the bottom inner wall, which can improve the light guiding effect.

[0010] Furthermore, the light guide is made of polypropylene material added with a light diffusing agent, having good light guiding performance.

[0011] The beneficial effects of the present utility model are as follows: The power supply connection to the light-emitting element is realized through the circuit board. The light-emitting element can be indirectly installed and fixed on the base housing through the circuit board, and no additional connection structure is required between the light-emitting element and the base housing. The setting of the light guide can play a role in guiding light, reducing the requirements for the installation position of the light-emitting element, and presenting various visual effects according to the different shapes of the light guide and the first mounting hole, improving the aesthetics of the indicator light.
