Description

Technical Field

[0001] The utility model relates to the technical field of shavers, in particular to a shaver with a sterilization function. Background Art

[0002] Shavers are used to shave beards and hairs and are one of the essential daily necessities for people. After shaving, users can only clean the shaver by simple methods such as washing with water and wiping. Over time, small hairs and dandruff are likely to accumulate inside, thus breeding bacteria and endangering human health. Therefore, technicians have designed a shaver with an ultraviolet sterilization function, which includes a PCBA board and a UV-LED arranged on the PCBA board. The PCBA board is electrically connected to the control circuit board of the body through a wire. When the PCBA board is powered on, the ultraviolet light emitted by the UV-LED passes through the light-transmitting cover plate and shoots out. However, there is a problem that the sterilization is not timely. In addition, the start of UV sterilization generally requires a control program to be programmed into the control circuit board of the body, so the chip processing performance requirements for the control circuit board are relatively high. Summary of the Invention

[0003] The purpose of the utility model is to provide a shaver with a sterilization function. When the protective cover covers the body, through the cooperation of the contacts on the body and the conductive sheets on the protective cover, the UV lamp beads are triggered to automatically sterilize, so that the cutter head of the body can be sterilized immediately.

[0004] The above technical purpose of the utility model is achieved through the following technical solutions: A shaver with a sterilization function includes a body and a protective cover detachably covering the body. The protective cover is internally provided with a first circuit board and a UV lamp bead electrically connected to the first circuit board. The light-emitting direction of the UV lamp bead faces the cutter head side of the body. At least one inner wall of the protective cover is provided with a conductive sheet. One end of the conductive sheet is electrically connected to the first circuit board, and the other end of the conductive sheet extends to the covering opening of the protective cover. The side end of the body is provided with a second circuit board and a contact electrically connected to the second circuit board. A total control circuit board electrically connected to the second circuit board is arranged inside the body. When the protective cover covers the body, the conductive sheet contacts the contact and conducts the first circuit board and the second circuit board, thereby realizing the automatic sterilization of the UV lamp bead.

[0005] Further, the conductive sheets are symmetrically arranged on both inner walls of the protective cover. One end of the conductive sheet is electrically connected to the first circuit board, and the other end of the conductive sheet extends to the covering opening of the protective cover.

[0006] Further, the protective cover includes an outer cover and an inner cover that are detachably fixed together. A receiving cavity is formed between the outer cover and the inner cover. The first circuit board is fixedly disposed in the receiving cavity. The inner cover is provided with a first avoidance notch for the UV lamp beads to protrude. The conductive sheet is disposed between the inner side wall of the outer cover and the outer side wall of the inner cover. The lower end of the inner cover is provided with a second avoidance notch corresponding to the position of the conductive sheet.

[0007] Further, a display lamp is electrically connected to the first circuit board. The display lamp is disposed on the other side of the first circuit board relative to the UV lamp beads. The protective cover is provided with an irradiation port corresponding to the position of the display lamp.

[0008] Further, when the UV lamp beads start sterilization, the first circuit board controls the display lamp to light up. When the UV lamp beads end sterilization, the first circuit board controls the display lamp to go out.

[0009] Further, two contacts are provided on one side of the fuselage. At least one side of the protective cover is provided with conductive sheets corresponding to the two contacts one by one.

[0010] In summary, the present utility model has the following beneficial effects:

[0011] 1. For the shaver of the present utility model, when the protective cover covers the fuselage, through the triggering cooperation between the contacts on the fuselage and the conductive sheets on the protective cover, the automatic sterilization of the UV lamp beads is realized, so that the cutter head of the fuselage can be sterilized immediately. On the other hand, there is no need to write the program for starting the sterilization of the UV lamp beads into the control circuit board, thus effectively reducing the requirements for the chip processing performance.

[0012] 2. For the shaver of the present utility model, by providing conductive sheets on both sides of the protective cover, conduction can be achieved even when the protective cover is reversed left and right when it is closed, so that the user does not need to consider the problem of reversing the protective cover left and right.

Detailed implementation mode

[0019] The present utility model will be further described below in conjunction with the accompanying drawings.

[0020] As Figures 1-5 Shown, a shaver with a sterilization function includes a body 10 and a protective cover 20 detachably covering the body 10. A first circuit board 30 and UV lamp beads 31 electrically connected to the first circuit board 30 are provided inside the protective cover 20. The light-emitting direction of the UV lamp beads 31 faces the cutter head side of the body 10. Conductive sheets 40 are provided on at least one inner wall side of the protective cover 20. One end of the conductive sheet 40 is electrically connected to the first circuit board 30, and the other end of the conductive sheet 40 extends to the closing port of the protective cover 20. A second circuit board 11 and a contact 12 electrically connected to the second circuit board 11 are provided at the side end of the body 10. A main control circuit board 13 electrically connected to the second circuit board 11 is provided inside the body 10. When the protective cover 20 covers the body 10, the conductive sheet 40 contacts the contact 12 and conducts the first circuit board 30 and the second circuit board 11, so as to realize the automatic sterilization of the UV lamp beads 31. In this embodiment, the sterilization duration of the UV lamp beads 31 is still controlled by the main control circuit board 13.

[0021] For the shaver of the present utility model, when the protective cover 20 covers the body 10, through the trigger cooperation between the contact 12 on the body 10 and the conductive sheet 40 on the protective cover 20, the automatic sterilization of the UV lamp beads 31 is realized, so that the cutter head of the body 10 can be sterilized immediately. On the other hand, there is no need to write the program for starting the sterilization of the UV lamp beads 31 into the main control circuit board 13, so that the requirement for the chip processing performance can be effectively reduced.

[0022] In some embodiments, conductive sheets 40 are symmetrically provided on both inner walls of the protective cover 20. One end of the conductive sheet 40 is electrically connected to the first circuit board 30, and the other end of the conductive sheet 40 extends to the closing port of the protective cover 20. For the shaver of the present utility model, by providing conductive sheets 40 on both sides of the protective cover 20, conduction can be realized even when the protective cover 20 is covered in a left-right reversed manner, so that the user does not need to consider the problem of left-right reverse covering of the protective cover 20. Thus, the user experience is greatly improved.

[0023] In some embodiments, the protective cover 20 includes an outer cover 21 and an inner cover 22 that are detachably fixed together. An accommodation cavity is formed between the outer cover 21 and the inner cover 22. The first circuit board 30 is fixedly disposed in the accommodation cavity. The inner cover 22 is provided with a first avoidance notch 221 for the UV lamp beads 31 to protrude. The conductive sheet 40 is disposed between the inner side wall of the outer cover 21 and the outer side wall of the inner cover 22. A second avoidance notch 222 is provided at the lower end of the inner cover 22 corresponding to the position of the conductive sheet 40. Through the above settings, it is convenient to assemble the first circuit board 30 and the UV lamp beads 31.

[0024] In some embodiments, a display lamp 32 is electrically connected to the first circuit board 30. The display lamp 32 is disposed on the other side of the first circuit board 30 relative to the UV lamp beads 31. The protective cover 20 is provided with an irradiation port corresponding to the position of the display lamp 32. Further, when the UV lamp beads 31 start sterilization, the first circuit board 30 controls the display lamp 32 to light up. When the UV lamp beads 31 end sterilization, the first circuit board 30 controls the display lamp 32 to go out. The display lamp 32 is used to remind the user that the shaver is performing UV sterilization at this time.

[0025] In some embodiments, two contacts 12 are provided on one side of the body 10. At least one side of the protective cover 20 is provided with conductive sheets 40 corresponding to the two contacts 12 one by one. Through this setting, the problem of the sterilization device being paralyzed due to damage to a single contact 12 or conductive sheet 40 is prevented, that is, it is ensured that when a certain contact 12 or a certain conductive sheet 40 is damaged, the shaver can still achieve the sterilization function.

[0026] The above is only the preferred embodiment of the present invention. Therefore, all equivalent changes or modifications made according to the structure, features and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
