Ways to implement the invention

[0007] The following embodiments are intended only to illustrate possible implementations of this invention; they are not intended to limit the scope of the invention. The term "one" or "at least one" before the nouns mentioned in the article does not limit the number. A "plurality" is also possible as needed. Changes to this number are also within the scope of the invention.

[0008] Fig. 1 to 9 show a preferred embodiment of the present invention. The electric suction cup 1 of the present invention includes a suction cup body 10, a backlight module 20, and a control panel 30.

[0009] The suction cup body 10 has a suction part 11, a handle 12, and an air extraction mechanism 13. The suction part 11 defines a chamber 14. The air extraction mechanism 13 can extract air from the chamber 14 so that the suction part 11 can adhere to a surface 2. In this embodiment, the air extraction mechanism 13 is arranged on the handle 12. The air extraction mechanism 13 can be connected to the chamber 14 through channels of the handle 12 and the suction part 11. The handle 12 is arranged on the suction part 11. The handle 12 has a gripping portion 15. The gripping portion 15 forms a first end portion 16 and a second end portion 17 at its opposite ends. The first end portion 16 has a first shell 161 and a second shell 162. A receiving space 163 is formed between the first shell 161 and the second shell 162. The first shell 161 forms at least one translucent section 164.The handle 12 is detachably attached to the suction part 11 by a plurality of screws 70. The backlight module 20 extends between the first shell 161 and the second shell 162 and is received in the receiving space 163. The backlight module 20 includes at least one light-emitting unit 21. The at least one light-emitting unit 21 can emit light toward the at least one light-transmitting portion 164. The control panel 30 has at least one display portion 31 corresponding to the at least one light-transmitting portion 164. In the present embodiment, the first shell 161 and the second shell 162 are detachably connected with the plurality of screws 70.

[0010] Thus, when holding the handle 12, the illumination state of the translucent portion 164 can be conveniently observed. The backlight module 20 can emit uniform light, creating a beautiful visual effect. Furthermore, the backlight module 20 extends between the first shell 161 and the second shell 162. The backlight module 20 can be large in size and positioned stably. When the first shell 161 is removed, the backlight module 20 is positioned in the first shell 161 or the second shell 162, facilitating maintenance and replacement.

[0011] In this embodiment, the control panel 30 is a flexible liquid crystal panel that has excellent effects on the direction, intensity, and color of light, offers comprehensive visual effects (such as light gradient effects, brightness intensity gradient effects, and different color changes in different blocks, etc.), and can easily adhere tightly to the first shell 161 and the second shell 162. An adhesive layer 50 is provided on the other side of the control panel 30. The control panel 30 is adhered to the first shell 161 and the second shell 162 by the adhesive layer 50. This allows a large control panel 30 to be used. In addition, the first shell 161 and the second shell 162 can be connected via the adhesive layer 50, so that the two are not easily separated from each other. Preferably, the backlight module 20 further includes at least one prism lens 60.The at least one prism lens 60 is disposed in the at least one translucent portion 164. The at least one translucent portion 164 is hollow. In other embodiments, it may be made of a translucent material. The at least one prism lens 60 removably fits into the at least one translucent portion 164. In other embodiments, it may be glued therein. The visual lighting effect may be enhanced by the prism lens 60.

[0012] The backlight module 20 also includes a pressure sensor unit 22 and a control unit 23. The control unit 23 is electrically connected to the pressure sensor unit 22 and the at least one light-emitting unit 21. The pressure sensor unit 22 can detect the air pressure in the chamber 14 and transmit an air pressure signal to the control unit 23. The control unit 23 controls the light-emitting unit 21 according to the air pressure signal.

[0013] In use, when the control unit 23 determines that the air pressure signal is in a first pressure state (such as a negative pressure state during air extraction), the control unit 23 controls the at least one light-emitting unit 21 to emit a first light (such as a green light, but not limited to it), as shown in Fig. 8. When the control unit 23 determines that the air pressure signal is in a second pressure state (such as a relief state when air is released), the control unit 23 controls the at least one light-emitting unit 21 to emit a second light (such as a red light, but not limited to it), as shown in Fig.9. The first light differs from the second light, so that the pressure state in the chamber 14 can be recognized by different light states or colors. In this embodiment, the second shell 162 forms a connecting portion 168 connected to the chamber 14. The electric suction cup 1 further includes a tube 80. The tube 80 is connected to the pressure sensor unit 22 and the connecting portion 168. The pressure sensor unit 22 can detect the air pressure of the chamber 14 through the tube 80. Preferably, the first shell 161 has a plurality of light-transmitting portions 164, and the backlight module 20 has a plurality of light-emitting units 21. The plurality of light-emitting units 21 are aligned with the plurality of light-transmitting portions 164.The control panel 30 has a plurality of display sections 31, wherein the plurality of display sections 31 are aligned with the plurality of light-transmitting sections 164. Each of the light-emitting units 21 is a light-emitting diode. The plurality of light-emitting units 21 can emit different or identical light, so that different lighting states can be displayed in the light-transmitting sections 164 depending on the air pressure state.

[0014] The backlight module 20 further includes a circuit board 24. The control unit 23, the light-emitting units 21, and the pressure sensor unit 22 are arranged on the circuit board 24. The first shell 161 is assembled with the second shell 162 in a first direction L1. The first shell 161 is provided with a first fitting groove 165 that is open in the first direction L1. The second shell 162 is provided with a second fitting groove 166 that is open in the first direction L1, corresponding to the first fitting groove 165. The circuit board 24 removably fits into the first fitting groove 165 and the second fitting groove 166. The circuit board 24 is spaced apart from the control panel 30 in a second direction L2. The first direction L1 is transverse to the second direction L2, thereby facilitating disassembly and maintenance.The circuit board 24 can be stably positioned on the first shell 161 and the second shell 162, whereby the electrical wires and tubes on the circuit board 24 and the second shell 162 are not easily bent and loosened by external force, thus achieving a stable installation and positioning effect. Preferably, the first shell 161 and the second shell 162 together form a through hole 167 on a side facing each other. The control unit 23 is exposed through the through hole 167. By pressing the control unit 23 on the control panel 30, the control unit 23 can control the suction state of the air suction mechanism 13. In this embodiment, the control unit 23 is a push button, but it is not limited thereto.

[0015] The electric suction cup 1 further includes a power supply unit 40, which is a battery. The second end portion 17 has a third shell 171 and a fourth shell 172. An installation space 173 is formed between the third shell 171 and the fourth shell 172. The power supply unit 40 is arranged in the installation space 173. The air exhaust mechanism 13 and the backlight module 20 are electrically connected to the power supply unit 40. The grip portion 15, the first end portion 16, and the second end portion 17 together form a wire channel, whereby the wires of the air exhaust mechanism 13 and the backlight module 20 can be electrically connected to the power supply unit 40 through the wire channel, so that the wires can be concealed and the power supply unit 40 can be separated from the backlight module 20. Therefore, they can be repaired and disassembled separately.

[0016] The circuit board 24 is also provided with an electrical socket 241 that is electrically connected to the light-emitting units 21 and the control unit 23. An electrical connector (such as a USB Type-C connector) can be electrically connected to an external power source and the electrical socket 241 to supply power.
