DETAILED DESCRIPTION OF THE INVENTION

[0015] First of all, it is to be mentioned that throughout this specification, including the following embodiment and claims, the directional terms are all based on the direction shown in the figures. Besides, same reference numerals used in the following embodiment and the appendix drawings designate same or similar elements or the structural features thereof.

[0016] Referring to FIGS. 1-3, a cleaning and sterilizing device 10 of the present invention includes an ultrasonic cleaner 20, a top cover 30 and an ultraviolet lamp 40.

[0017] The ultrasonic cleaner 20 has a body 21 having a cleaning tank 22. A cleaning basket 23 is disposed in the cleaning tank 22 for accommodating objects. A control panel cover 24 is disposed on the top edge of the body 21 and surrounds the cleaning tank 22. A circuit board 26 is disposed in the control panel cover 24 and provided with two first electrical contacts 27 arranged abreast. One of the first electrical contacts 27 is the positive electrode and the other is the negative electrode. The two first electrical contacts 27 are inserted in two first through holes 25 of the control panel cover 24. Besides, the body 21 is provided with at least one vibration element below the cleaning tank 22. The vibration element, which belongs to the prior art and is not shown in the figures, can be controlled by the circuit board 26 to generate ultrasonic frequency oscillation.

[0018] As shown in FIG. 3, the top cover 30 has a covering plate 31 and a handle 36. The covering plate 31 is provided at the center thereof with an elongated opening 32 penetrating through top and bottom surfaces of the covering plate. The top surface of the covering plate 31 has an accommodating trough 33 communicating with the opening 32 and an engaging portion 34 provided around the opening 32. The covering plate 31 is provided on one side thereof with two second through holes 35 arranged abreast and communicating with the accommodating trough 33. The handle 36 is disposed on the top surface of the covering plate 31 in a screwing manner and covers the accommodating trough 33. In this way, on one hand, the user can hold the handle 36 to make the top cover 30 cover the opening of the cleaning tank 22. At this time, the control panel cover 24 receives the bottom surface of the covering plate 31 for support. On the other hand, the user can hold the handle 36 to detach the top cover 30 from the opening of the cleaning tank 22 to conveniently add water into the cleaning tank 22 or pour water from it.

[0019] The ultraviolet lamp 40 is disposed on the engaging portion 34 of the covering plate 31 and exposed on the bottom surface of the covering plate 31 through the opening 32. Two conductive wires 41 are connected to two ends of the ultraviolet lamp 40 respectively. The two conductive wires 41 are both located in the accommodating trough 33, and an end of each of the conductive wires 41 is connected to a second electrical contact 42. That means there are two second electrical contacts 42, one of which is the positive electrode and the other is the negative electrode. The two second electrical contacts 42 are inserted in the two second through holes 35 of the covering plate 31. In this way, as shown in FIGS. 4 and 5, when the opening of the cleaning tank 22 is covered by the top cover 30, the ultraviolet lamp 40 directly faces the cleaning tank 22, and the two second electrical contacts 42 of the ultraviolet lamp 40 contact the two first electrical contacts 27 of the ultrasonic cleaner 20, so that the electrical conduction of the ultraviolet lamp 40 is achieved. After that, when the power is turned on, the ultraviolet lamp 40 can be controlled to generate ultraviolet to sterilize the object located in the cleaning tank 22. In addition, an arc reflector 43 may be further disposed above the ultraviolet lamp 40, as shown in FIG. 3. Through the reflector 43, the ultraviolet generated by the ultraviolet lamp 40 can be relatively more concentrated to irradiate on the surface of the object.

[0020] It can be known from the above description that the cleaning and sterilizing device 10 of the present invention can clean the object by ultrasonic cleaning or sterilize the object by irradiating it by the ultraviolet lamp, thereby attaining the objective of thorough cleaning and sterilization. Besides, by the detachable design of the top cover 30, the ultraviolet lamp 40 can be used right after the top cover 30 covers the cleaning tank 22, and it is convenient to add water or pour water after the top cover 30 is detached. Therefore, the ultrasonic cleaner 20 and the ultraviolet lamp 40 are quite convenient to be used in coordination.
