Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a safe electrical connection structure of an electric hair dryer spray device. Background Art

[0002] In a hair dryer, the structure of a high-speed hair dryer is mainly characterized by its air inlet and outlet structure compared with a traditional hair dryer. The air inlet of a high-speed hair dryer is arranged at the bottom of the handle, and a high-speed blower is arranged in the handle to suck the air into the cylinder at the upper end of the handle. A corresponding air duct is arranged in the cylinder to blow the air out from the air outlet. Specifically, the air duct in the cylinder is annular, and the air outlet is also annular for blowing out high-speed wind. Therefore, the high-speed hair dryer can be hollowed out or sealed in the middle of the air outlet, and it does not participate in the air outlet. At present, there is a solution that a spray device is arranged in the middle of the air outlet of the high-speed hair dryer to spray aromatherapy spray, which acts on the hair together with the wind blown out from the air outlet, so that the hair has a fragrance. Since the aromatherapy liquid is stored in the spray device, and an atomizing component needs to be arranged to atomize the aromatherapy liquid, the atomizing component needs to be supplied with electric energy. Since the spray device is small in size, it is not convenient to take it out frequently for charging or replacing the battery. Therefore, the spray device generally needs to be electrically connected to the hair dryer body to obtain power from the hair dryer body. If the aromatherapy liquid in the spray device leaks, it is easy to cause a short circuit at the electrical connection between the spray device and the hair dryer body, affecting the normal operation of the spray device.

[0005] Specifically, the cross-sectional area of ​​the atomizing component is larger than that of the liquid containing component, and the first electrical connection component is arranged on the rear end surface of the atomizing component beyond the liquid containing component, and correspondingly, the second electrical connection component is arranged at the bottom of the supporting groove.

[0006] Specifically, the first electrical connection component is composed of two electrodes, and the two electrodes of the first electrical connection component are respectively arranged at two ends of the atomization component beyond the liquid holding component; correspondingly, the second electrical connection component is also composed of two electrodes, and the two electrodes of the second electrical connection component are respectively arranged at two ends of the bottom of the supporting groove.

[0007] Specifically, the two electrodes of the first electrical connection component are elastic pressing electrodes, which include a fixing seat, an elastic component and a contact head, and the contact head is electrically connected to the fixing seat through the elastic component.

[0008] Specifically, the two electrodes of the second electrical connection component adopt an electrode sheet structure, which includes a support mounting seat and a fixed metal sheet. The support mounting seat is fixed on the hair dryer body, and the fixed metal sheet is fixedly connected to the support mounting seat and electrically connected to the control circuit board of the hair dryer body.

[0009] The beneficial effect of the utility model is that by arranging the electrical connection components on the spray device that are electrically connected to the hair dryer body on both sides of the atomizing component at the front end of the spray device, the two connecting electrodes can be effectively separated and away from the liquid containing component, thereby avoiding the problem of short circuit at the electrical connection between the spray device and the hair dryer body, and effectively improving the safety performance of the electrical connection structure of the spray device.

[0014] Example 1, reference Figure 1-4A safe electrical connection structure for a hair dryer spray device comprises a hair dryer body 1 and a spray device body 2, wherein a receiving groove 3 for plugging and fixing the spray device body 2 is arranged in the middle position of the front air outlet 11 of the hair dryer body 1; the spray device body 2 is composed of a front atomizing component 21 and a rear liquid receiving component 23, and correspondingly, the receiving groove 3 is composed of a front supporting groove portion 31 and a rear plugging groove portion 32; a first electrical connection component 4 is arranged on the atomizing component 21, and a second electrical connection component 5 is correspondingly arranged in the supporting groove portion 31; the second electrical connection component 5 is electrically connected to a control circuit board in the hair dryer body 1.

[0015] In this embodiment, the spray device body 2 is composed of an atomizing component 21 at the front end and a liquid containing component 22 at the rear end, wherein the atomizing component 21 is used to contain an electronic atomizing sheet, the first electrical connection component 4 provided on the atomizing component 21 obtains power from the second electrical connection component 5 of the supporting groove 31 on the hair dryer body 1, and the liquid containing component 22 is used to contain an aromatherapy solution, and a capillary fiber strip is provided in the liquid containing component 22 to suck the aromatherapy solution in the liquid containing component 22 to the electronic atomizing sheet of the atomizing component 21 for atomization. The spray generated after the atomizing component 21 atomizes the aromatherapy solution is blown forward by the wind blown out from the air outlet 11 of the hair dryer body 1 to act on the hair that the hair dryer body 1 is aimed at, so that the hair has a certain fragrance.
