[0029] In the power strip device provided in the present application, the fixing component 200 includes an air extraction component 220 and a suction cup 230, so that the fixing component 200 can be firmly adsorbed on the contact surface, and the power strip body 100 and the fixing component 200 are connected by a magnetic connection component 300. Therefore, the power strip body 100 can be used alone and stably placed on a contact surface that is not suitable for adsorption using a suction cup, or it can be adsorbed on the fixing component 200, and the air extraction component 220 is activated through the electrical connector 400, so that the fixing component 200 is firmly adsorbed on a relatively smooth contact surface, thereby improving the fixing effect of the power strip body 100 and further improving the user experience of the power strip body 100.

[0030] Specifically, in this embodiment, the fixing component 200 is placed on a relatively smooth contact surface (not shown). The suction cup 230 is located on the bottom side of the fixing shell 210 and adsorbs the contact surface. The suction component 220 has a suction nozzle (not shown), which is connected to the space between the suction cup 230 and the contact surface, and the gas in the space is extracted to form a negative pressure, thereby firmly adsorbing the fixing component 200 on the contact surface. The contact surface can be the ground, the wall, the outer surface or the inner surface of an object or equipment, etc.

[0031] In some embodiments, the power strip housing 110 includes a face shell 111 and an end cover 112 . The face shell 111 is provided with an opening. The end cover 112 is connected to the face shell 111 to cover the opening. The end cover 112 and the face shell 111 enclose a first accommodating space to accommodate the power supply 120 .

[0032] Exemplarily, referring to FIG1 , a concave cavity is formed in the face shell 111, and the end cover 112 covers the opening of the concave cavity to form a first accommodation space in the face shell 111. The top surface of the face shell 111 is provided with a plurality of sockets, which can be used to insert a two-pin plug, a three-pin plug, a USB plug, etc. A power switch, an overload protector, and a surge absorber, etc. (not shown in the figure) are provided in the first accommodation space, and the power supply 120 is also provided in the first accommodation space. When the power strip body 100 is connected to the power supply, the power supply 120 is also connected to the power supply. By providing the face shell 111 and the end cover 112 and forming the first accommodation space, the power supply 120 is provided in the first accommodation space, which can protect the power supply 120 from collision, improve durability, and prevent leakage, thereby improving the safety of the power strip device.

[0033] In some embodiments, the fixed shell 210 includes a side shell 211, a first cover body 212 and a second cover body. The first cover body 212 and the second cover body are relatively covered on both sides of the side shell 211. The side shell 211, the first cover body 212 and the second cover body are enclosed to form a second accommodating space, and the exhaust assembly 220 is arranged in the second accommodating space.

[0034] Exemplarily, referring to FIG. 1 and FIG. 3 , the side shell 211 is approximately rectangular ring-shaped, and the side shell 211 forms openings at the upper edge and the lower edge, respectively. The first cover 212 and the second cover (which is blocked by the side shell 211 and not shown) are respectively covered on the upper and lower sides of the side shell 211, and cover one opening respectively. The side shell 211, the first cover 212 and the second cover form a second accommodation space enclosed between them, and the second accommodation space can be used to accommodate the suction component 220. The suction cup 230 is connected to the bottom side of the second cover, and the suction cup 230 is provided with a second through hole 230a, and the second cover is provided with a through hole (not shown in the figure), and the second through hole 230a corresponds to the through hole. The suction component 220 can extend into the space between the suction cup 230 and the contact surface through the second through hole 230a and the through hole, and extract the gas between the suction cup 230 and the contact surface to form a negative pressure, so that the suction cup 230 is firmly adsorbed on the contact surface.

[0035] In some embodiments, the end cover 112 is provided with a first mounting hole 112 a , and the first magnetic connector 310 is nested in the first mounting hole 112 a .

[0036] Exemplarily, referring to FIG3 , the end cover 112 is provided with a plurality of first mounting holes 112a, and the plurality of first mounting holes 112a all penetrate the end cover 112 along the thickness direction of the end cover 112. In the present embodiment, the number of the first mounting holes 112a is 5, wherein two first mounting holes 112a are respectively provided on the two opposite long side edges of the end cover 112, and one first mounting hole 112a is provided on the short side edge of the end cover 112, and the first mounting holes 112a are all in the shape of long strips. The first magnetic connector 310 includes five magnets, each of which is nested in a first mounting hole 112a. The second magnetic connector 320 is a metal part made of ferromagnetic material, and the material is iron, cobalt or nickel, etc. The first magnetic connector 310 and the second magnetic connector 320 attract each other through magnetic force, so that the end cover 112 fits with the first cover body 212, thereby making the strip body 100 fastened and mounted on the fixing assembly 200. By setting the first mounting hole 112a in the end cover 112, the first magnetic connector 310 can be nested in the first mounting hole 112a without protruding from the surface of the end cover 112, so that the end cover 112 and the first cover body 212 fit better and the installation effect of the strip body 100 on the fixing assembly 200 is better.

[0037] In other embodiments, the first magnetic connector 310 may also be a metal member made of ferromagnetic material, and the second magnetic connector 320 may be a magnet, which may also attract each other to make the end cover 112 and the first cover body 212 fit together.

[0038] In other embodiments, the first magnetic connector 310 and the second magnetic connector 320 may both be magnets, and the magnetic poles of the first magnetic connector 310 and the second magnetic connector 320 on opposite sides are different, and they may attract each other to fit the end cover 112 with the first cover body 212 .

[0039] In some embodiments, at least one of the first magnetic connector 310 and the second magnetic connector 320 includes a plurality of bar magnets. In this embodiment, the five magnets are all in the shape of long strips, so as to cover more areas along the edge of the end cover 112, and achieve better adsorption effect. Corresponding to the magnets, the metal piece is also in the shape of long strips, which helps to make the strip body 100 more firmly adsorbed on the fixing assembly 200.

[0040] In some embodiments, the second magnetic connector 320 is disposed on the first cover 212 and is located on a side of the first cover 212 opposite to the second cover.

[0041] Exemplarily, the second magnetic connector 320 is a metal part made of ferromagnetic material, and the number of the second magnetic connectors 320 is five, and each second magnetic connector 320 is arranged corresponding to a first magnetic connector 310. The five second magnetic connectors 320 are all arranged on the side of the first cover 212 away from the end cover 112, and can be fixedly connected to the first cover 212 by bonding or welding. By arranging the second magnetic connector 320 on the side of the first cover 212 away from the end cover 112, the second magnetic connector 320 will not be exposed to the air, slowing down the corrosion rate of the second magnetic connector 320 and improving the durability.

[0042] In some embodiments, the power supply 120 includes a DC-AC power module 121, and the DC-AC power module 121 is electrically connected to the exhaust component 220. Exemplarily, the DC-AC power module 121 includes an AC (alternating current) component and a DC (direct current) component, and the AC component and the DC component are connected to convert alternating current into direct current. An interface is provided on the bottom side of the DC component, and the interface is connected to the first electrical connection part 410 through an electric wire, so that the first electrical connection part 410 can output direct current. The exhaust component 220 can continue to work under the power supply of the DC component without being connected to an external power supply, thereby simplifying the overall structure of the power strip device.

[0043] In some embodiments, one of the first electrical connection portion 410 and the second electrical connection portion 420 includes an electrical contact 411 , and the other includes a spring contact pin 421 .

[0044] Exemplarily, referring to FIG. 1 and FIG. 2 , the first electrical connection portion 410 includes two electrical contacts 411, both of which are arranged on the left side of the end cover 112, and a third strip-shaped mounting hole 112b is arranged on the left side of the end cover 112, and the third mounting hole 112b is arranged opposite to the first mounting hole 112a located at the short side edge of the end cover 112, and the two electrical contacts 411 are nested in the through hole. The second electrical connection portion 420 includes two spring contact pins 421, both of which are arranged on the top side of the first cover body 212, and correspond to one electrical contact 411 respectively. It can be understood that when the first magnetic connector 310 and the second magnetic connector 320 attract each other, so that the end cover 112 and the first cover body 212 fit together, the electrical contact 411 abuts against the spring contact pin 421, so that the power supply 120 is electrically connected to the air extraction component 220, and the power supply 120 converts the AC power into DC power and can supply power to the air extraction component 220. The electrical contact 411 and the spring contact pin 421 have high connection stability and good sealing, and are not easy to leak liquid and damage the power strip body 100 and the fixing component 200.

[0045] In some other embodiments, the first electrical connection portion 410 is a spring contact pin 421 , and the second electrical connection portion 420 is an electrical contact point 411 , which can also electrically connect the power supply 120 and the air extraction assembly 220 .

[0046] In some embodiments, the vacuum assembly 220 includes a circuit board 221, an air pump 222 and an air release switch 223, the circuit board 221 is electrically connected to the air pump 222 and the air release switch 223, the air pump 222 is used to extract and store the gas between the suction cup 230 and the contact surface, and the air release switch 223 is used to release the gas stored in the air pump 222 into the space between the suction cup 230 and the contact surface.

[0047] Exemplarily, a mounting plate 240 is provided on the second cover, a circuit board 221 is provided on the mounting plate 240, and the circuit board 221 is connected to the AC-DC power module 121 through a wire. The air pump 222 is fixedly provided on the second cover, and is electrically connected to the circuit board 221 through a wire (not shown) or other connectors. Along the thickness direction of the second cover, the second cover is provided with a first through hole, and the air pump 222 is connected to the adsorption space through the first through hole, and can extract air from the adsorption space to make the adsorption space in a negative pressure state.

[0048] The circuit board 221 is integrated with a controller (not shown), and the controller can start the air pump 222 or control the air pump 222 to stop working by sending an electrical signal to the air pump 222 .

[0049] The second cover body is provided with a deflation switch 223. When the deflation switch 223 is triggered, the air pump 222 stops sucking air from the adsorption space and delivers air to the adsorption space to release the negative pressure state. In this embodiment, the deflation switch 223 is electrically connected to the circuit board 221. However, when the deflation switch 223 is triggered, the controller receives an electrical signal from the deflation switch 223 and controls the air pump 222 to stop working. In other embodiments, the deflation switch 223 can also be a spring or a pin, etc. The deflation switch 223 abuts against the air pump 222. When the deflation switch 223 is subjected to force, it can squeeze and trigger the mechanical switch (not shown) of the air pump 222, so that the air pump 222 switches the working state of air extraction and air delivery.

[0050] In some embodiments, the vacuum assembly 220 also includes a trigger member 225 and a push switch 226. The push switch 226 is disposed in the power strip housing 110 and is electrically connected to the circuit board 221. The push switch 226 is used to start the air pump 222. The trigger member 225 is disposed corresponding to the push switch 226, and at least part of the trigger member 225 is located in the adsorption space. The trigger member 225 is used to press against the contact surface when the suction cup 230 is deformed in a direction close to the contact surface to trigger the push switch 226.

[0051] For example, referring to Fig. 3, two push switches 226 are fixedly arranged on the mounting plate 240. The push switches 226 are electrically connected to the circuit board 221 through wires (not shown) or other connectors. When the push switches 226 are pressed and triggered, the push switches 226 send an electrical signal to the circuit board 221, so that the air pump 222 starts pumping air.

[0052] The mounting plate 240 is provided with two first through-holes, and each push switch 226 corresponds to a first through-hole. The suction cup 230 is provided with two second through-holes 230a, and each second through-hole 230a corresponds to a first through-hole. The trigger member 225 is in the shape of a plunger, and the bottom end of the trigger member 225 is located in the adsorption space with a certain gap between it and the contact surface, and the top end is fixedly connected to the push switch 226. When in use, after placing the power strip device in the area to be fixed, the power strip device is pressed down with force, and the suction cup 230 is deformed by the force, so that the bottom end of the trigger member 225 is pressed against the contact surface. The trigger member 225 is supported by the contact surface and is fed back upward to the push switch 226, so that the push switch 226 is triggered to start the air pump 222 to extract air. By setting the trigger member 225 and the push switch 226, when fixing the power strip device, one only needs to press down hard to start the air pump 222 to evacuate air, so that the entire power strip device is firmly installed on the adsorption surface. No other steps are required, the operation is simple and the efficiency is extremely high.

[0053] In some embodiments, the vacuum assembly 220 also includes a deflation button 224, the side shell 211 is provided with a second mounting hole 211a, the deflation button 224 is passed through the second mounting hole 211a, and one end of the deflation button 224 is located on the outside of the side shell 211, and the other end is located in the second accommodating space and corresponds to the deflation switch 223, and the deflation button 224 is used to trigger the deflation switch 223.

[0054] Referring to FIG3 , illustratively, the second mounting hole 211a is located on one of the short side edges of the side shell 211. One end of the deflation button 224 is located outside the side shell 211 for easy touching by the user, and the other end of the deflation button 224 is located inside the side shell 211 and corresponds to the deflation switch 223. When the user presses the deflation button 224 from outside the side shell 211 into the second accommodating space, the deflation button 224 triggers the deflation switch 223, causing the air pump 222 to exhaust air into the adsorption space, thereby releasing the adsorption state of the suction cup 230. By providing the second mounting hole 211a and the deflation button 224 in the side shell 211, the negative pressure environment in the adsorption space can be easily released, and the position of the fixing component 200 can be easily moved and adjusted.

[0055] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
