Embodiment 1

[0014] In order to overcome the defect that MP3 does not have weighing and banknote checking functions in the prior art, the invention provides a kind of MP3 with weighing and banknote checking functions, such as figure 1 and 2 As shown, it includes a housing 1 and a built-in battery 9, and the housing 1 is provided with a weighing device and an ultraviolet money detector lamp 6, and the ultraviolet money detector lamp 6 is connected to the battery 9 through a switch 10 controlling it. The ultraviolet currency detector lamp 6 and the switch are embedded in the side of the housing 1 .

[0015] The MP3 function provided in this embodiment is diversified, which brings convenience to people's life. It has a weighing function, which is convenient for people to weigh the items that need to be weighed when they consume, and has a banknote detection function to prevent people from consuming The economic loss caused by counterfeit money is small in size, convenient to carry, simple in...

Embodiment 2

[0017] The weighing device as described in Embodiment 1 comprises hook body 5, gravity sensor 7, amplifying circuit 8, A / D converter 7 and microprocessor 4, and described MP3 also comprises display screen 11, built-in circuit board 2, so Described gravity sensor 7, amplifying circuit 8, A / D converter 3, microprocessor 4 and display screen 11 are connected with circuit board 2 respectively, and gravity sensor 7 is connected with microprocessor 4 through amplifying circuit 8, A / D converter 3 Connection, the microprocessor 4 is connected with the display screen 11, and the circuit board 2 is connected with the storage battery 9.

[0018] Such as figure 2 It is not difficult to see that the hook body 5 passes through the housing 1, the hook body 5 is connected to the gravity sensor 7 arranged in the housing 1, and the gravity sensor 7 is arranged between the hook body 5 and the lower inner wall of the housing 1, The amplifying circuit 8 , A / D converter 3 and microprocessor 4 are...

Abstract

The invention specially provides an MP3 (moving picture experts group audio layer-3) with weighing and money detecting functions. The MP3 comprises a shell and a built-in storage battery and is characterized in that a weighing unit and an ultraviolet money detecting lamp are arranged on the shell, and the ultraviolet money detecting lamp is connected with the storage battery by controlling a switch of the ultraviolet money detecting lamp. Compared with the prior art, the MP3 has the advantages that the MP3 is expanded in function by additionally provided with the weighing unit and the money detecting function, and convenience is brought to people to weigh items needing to be weighed during consumption, so that financial loss of the people due to fake money during consumption is avoided; the MP3 is small in size, convenient to carry, simple in structure, reasonable in design and highly practical.

Description

technical field [0001] The invention specifically relates to an MP3 with the functions of weighing and money checking. Background technique [0002] Nowadays, MP3 is widely used, but the function of existing MP3 is relatively single, which can no longer meet people's daily needs. When people buy some items that need to be weighed, such as rice, vegetables, etc., they may be deceived by the seller. Things were short of catties and taels, and people could not correct the catties on the spot because they did not have suitable weighing tools at that time, and they found out afterwards that they were cheated but could no longer claim compensation. In addition, when people consume, they usually receive counterfeit money because they cannot distinguish money, resulting in economic losses. However, the existing money detectors are large in size and not easy to carry. MP3 is small in size and easy to carry, but it does not have the functions of weighing and money checking. Content...
