Description

Technical Field

[0001] This utility model relates to the field of mobile phone accessories technology, and in particular to a mobile phone cleaning device. Background Technology

[0002] Existing mobile phone cleaning tools mainly include various cleaning cloths, cleaning wipes, and spray bottles with cleaning cloths attached to their surfaces. These tools are simply designed and do not consider how to comfortably hold and apply force, nor do they take into account the overall shape of the phone. The resulting shortcomings include: 1. Inconvenient for hand grip and application of force. Cleaning is mainly achieved by holding, pressing, and wiping back and forth with the fingers, which does not provide a comfortable grip and does not allow for full utilization of hand strength. 2. They do not provide multiple wiping surfaces to simultaneously clean the phone screen, back, and sides. Summary of the Invention

[0003] To address the shortcomings of existing mobile phone cleaning tools, such as inconvenience in gripping and applying force, and the inability to provide multiple wiping surfaces, this invention provides a hand-held box-type mobile phone cleaning device. Through its mechanical structure, it is convenient for hand gripping and applying force, enabling more efficient wiping and cleaning of various parts of the mobile phone.

[0004] The technical solution adopted by this utility model is: a hand-held box-type mobile phone cleaning device, which consists of three parts: a main box, a bottom box, and a rotating and pressing structure.

[0005] The main body is a single-piece structure, divided into a top outer shell, left outer shell, right outer shell, left inner wall, right inner wall, and base. The front ends of the top outer shell, left and right outer shells, and left and right inner walls are curved. The inner surfaces of the left and right inner walls transition to the front edges with rounded corners, and the rear ends of the left and right inner walls are curved surfaces, connecting to the rear ends of the left and right outer shells respectively. The edges where the top outer shell connects to the left and right outer shells are rounded. The upper surface of the base has curved surfaces at both the front and rear ends, and the lower surface has a first semi-circular groove opening downwards. The left outer shell has a semi-circular notch with the same cross-sectional shape as the first semi-circular groove. The lower part of the base has a first and a second wedge at both the front and rear ends, both wedges are inclined at 10 degrees from the vertical direction, and the bottom edges of both wedges are rounded. The left inner cavity is between the top outer shell, left outer shell, and left inner wall; the right inner cavity is between the top outer shell, right outer shell, and right inner wall; and the receiving cavity is between the bottom of the top outer shell, left and right inner walls, and the upper surface of the base. The inner surfaces of the left and right inner walls and the upper surface of the base have concave surfaces. The concave surfaces on the left and right inner walls are 17mm long vertically and 44.9mm long at the top edge and 53mm long at the bottom edge, with the top and bottom edges connected by an arc. The concave surface on the upper surface of the base is 82mm long horizontally and 71mm long at the bottom edge. The three concave surfaces are connected together to a depth of 0.6mm and are covered with a 0.6mm thick microfiber cloth that matches the shape of the concave surfaces for cleaning. The rear end of the top outer shell is thicker than the rest of the top outer shell. Its upper and rear surfaces each have concave surfaces, each measuring 82mm × 4.5mm. The two concave surfaces are connected to each other to a depth of 0.6mm and are covered with a 0.6mm thick microfiber cloth that matches the shape of the concave surfaces for cleaning. The four outer edges at the rear end of the main box are rounded. The main box is made of plastic.

[0006] The upper surface of the base box has a second semi-circular groove with an upward opening. The left and right sides protrude forward from the center and have left and right bevels. A third wedge is located between the protruding parts on both sides of the base box, and a fourth wedge is located at the rear end of the base box. Both wedges are inclined at 10 degrees from the vertical direction, and the top edges of both wedges are rounded. The edges where the lower surface of the base box meets the left and right sides are also rounded. The base box is made of plastic.

[0007] The rotating pressing mechanism is a single, integrated structure, consisting of a cylindrical rotating shaft, a left connecting rod, a right connecting rod, a pressing head, and a knob. The left and right sides of the cylindrical rotating shaft are connected to the rear end of the pressing head via the left and right connecting rods, and the edges of the left and right sides and top surface of the pressing head are rounded. The lower end of the knob is connected to the left end of the cylindrical rotating shaft. The lower part of the pressing head has a semi-cylindrical, concave curved surface measuring 82mm × 23.8mm, covered with a 0.6mm thick, third-layer microfiber cloth that matches the shape of the curved surface and serves a cleaning function. The rotating pressing mechanism is made of plastic.

[0008] The combination and structural relationship of each part are as follows: the pressing head of the rotating pressing structure is placed above the front end of the base of the main box, and the cylindrical rotating shaft is as follows: Figure 21 The first semi-circular groove is embedded in the direction indicated by the middle arrow. The left and right connecting rods are placed in the left and right inner cavities respectively, and the knob is located on the outer side of the left outer shell. The third and fourth wedges of the bottom box are respectively connected to the first and second wedges of the main box as follows: Figure 22 The first and second semi-circular grooves, as indicated by the middle arrow, fit together to form a single cylindrical groove. A cylindrical rotating shaft is placed within this groove. The protruding parts on both sides of the bottom box are positioned on the left and right sides of the first wedge, with the left and right inclined surfaces positioned below the left and right connecting rods, respectively. The diameter of the cylindrical groove is 0.4mm larger than the diameter of the cylindrical rotating shaft, allowing the shaft to rotate within it. The left and right widths of the left and right inner cavities are 0.4mm larger than the left and right widths of the left and right connecting rods, allowing the left and right connecting rods to rotate upwards within the left and right inner cavities about the cylindrical rotating shaft as their axis. A 0.2mm gap is left between the rear end of the pressing head and the front ends of the top outer shell, left and right outer shells, and left and right inner walls. A 0.2mm gap is also left between the knob and the left outer shell. Therefore, the entire pressing structure can rotate upwards about the cylindrical rotating shaft, as shown in Figures 9 and 10. The maximum rotation angle is 22 degrees; at this angle, the left and right connecting rods touch the top outer shell. Pushing the phone into the receiving cavity between the pressing head and the base can lift the pressing head and drive the knob to rotate. If resistance is applied to the knob at the same time, the pressing head and the base can clamp the phone.

[0009] The assembled utility model has an external shape of a box and a knob attached to the left side of the box. The edges connecting the top, bottom, left, and right sides of the box are rounded for comfortable grip. Externally, the box is 33.4mm long vertically, 96.8mm wide horizontally, and 66mm long front to back; the knob is 30mm long vertically, 8.6mm wide horizontally, and 8mm long front to back. Internally, the receiving cavity is 82mm wide horizontally and 17mm high vertically. When the pressing head is rotated upwards to its maximum angle, the distance between its bottom and the upper surface of the base is also 17mm. These internal dimensions are sufficient to accommodate most candybar smartphones of different widths and thicknesses. Behind the receiving cavity is a rectangular opening of 82mm x 17mm, through which medical alcohol can be sprayed into the receiving cavity, adhering to the surface of the first microfiber cloth and the rear half of the third microfiber cloth.

[0010] The assembled utility model provides four wiping surfaces around the phone, namely the curved surface under the pressing head, the upper surface of the base, the inner surface of the left inner wall, and the inner surface of the right inner wall. The corresponding parts of the phone to be wiped are the screen, the lens or the back of the phone below the lens, and the left and right sides. At the same time, it also provides two connected wiping surfaces at the rear end of the top shell of the main box, for wiping the back of the phone above the lens and the top and bottom of the phone.

[0011] The essential technical features of the above technical solution are summarized as follows: 1. The main box, the bottom box, and the rotating pressing structure constitute the box structure. A rotatable pressing head is located at the front end, and a rotatable knob is located on the left side. 2. Microfiber cloth is adhered to the upper surface of the base, the inner surfaces of the left and right inner walls, and the semi-cylindrical curved surface below the pressing head. 3. The main box and the bottom box are fitted together, leaving a cylindrical groove and left and right inner cavities. A cylindrical rotating shaft is placed in the groove and can rotate. Left and right connecting rods are placed in the left and right inner cavities respectively. The rotating pressing structure as a whole can rotate upwards with the cylindrical rotating shaft as its axis. 4. The front end of the base and the lower part of the pressing head are curved surfaces. Pushing the phone into the receiving cavity between them can lift the pressing head and drive the knob to rotate. If resistance is applied to the knob simultaneously, the pressing head and the base can clamp the phone.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model provides a fixed, box-shaped shape, offering a stable and comfortable grip for the hand. It changes the existing method of using fingers to hold, press, and wipe the phone to a method of gripping and pulling back and forth, allowing the hand to exert force as a whole. Through the structural features of this utility model, the required pressure for wiping the phone is fully provided. 2. This utility model provides four wiping surfaces surrounding the phone, allowing simultaneous wiping of the screen, back of the phone or lens, and sides. The four wiping surfaces have a fixed shape, ensuring full contact with the phone body during wiping. These two points enable convenient and efficient phone cleaning, improving both cleaning effect and efficiency.

[0047] The following are specific implementation methods: This utility model is derived from... Figures 11 to 15 The main box shown, as Figure 16 , Figure 17 The bottom box shown and as Figures 18 to 20The rotating and pressing structure shown is composed of the following parts: the main box body includes a top outer shell 1, a left outer shell 2, a right outer shell 3, a left inner wall 4, a right inner wall 5, and a base 6. The lower surface of the base 6 has a first semi-circular groove 7 with an opening facing downwards. The lower front and rear ends of the base 6 have a first wedge 8 and a second wedge 9. The left inner cavity 10 is between the top outer shell 1, the left outer shell 2, and the left inner wall 4. The right inner cavity 11 is between the top outer shell 1, the right outer shell 3, and the right inner wall 5. The receiving cavity 12 is between the bottom end of the top outer shell 1, the left inner wall 4, the right inner wall 5, and the upper surface of the base 6. The inner surfaces of the left inner wall 4, the right inner wall 5, and the upper surface of the base 6 have concave surfaces and are covered with a first microfiber cloth. The concave surface at the rear end of the top outer shell 1 is covered with a second microfiber cloth. The upper surface of the bottom box body has a second semi-circular groove 13 with an opening facing upwards. The left and right sides protrude forward from the middle part and have a left inclined surface 14 and a right inclined surface 15. A third wedge 16 is provided between the forward-protruding parts on both sides. A fourth wedge 17 is provided at the rear end of the bottom box body. The rotating pressing structure includes a cylindrical rotating shaft 18, a left connecting rod 19, a right connecting rod 20, a pressing head 21, and a knob 22. The lower part of the pressing head 21 has a semi-cylindrical concave curved surface, on which a third microfiber cloth is attached.

[0048] The third and fourth wedges 16 and 17 of the bottom box body are respectively engaged with the first and second wedges 8 and 9 of the main box body. The forward-protruding parts on both sides of the bottom box body are positioned on the left and right sides of the first wedge 8. The first semi-circular groove 7 and the second semi-circular groove 13 are joined to form a cylindrical groove. The cylindrical rotating shaft 18 of the rotating pressing structure is placed in it and can rotate. The left connecting rod 19 of the rotating pressing structure is placed in the left inner cavity 10, and the right connecting rod 20 is placed in the right inner cavity 11. The left connecting rod 19 and the right connecting rod 20 can rotate upward about the cylindrical rotating shaft 18 as the axis. The left inclined surface 14 and the right inclined surface 15 are respectively placed below the left connecting rod 19 and the right connecting rod 20. The pressing head 21 is placed above the front end of the base 6 of the main box body, and the knob 22 is placed on the outside of the left outer shell 2 of the main box body. The rotating pressing structure, including the cylindrical rotating shaft 18, the left connecting rod 19, the right connecting rod 20, the pressing head 21, and the knob 22, can rotate upward as a whole around the cylindrical rotating shaft 18 until the left connecting rod 19 and the right connecting rod 20 touch the top outer shell 1. At this time, the rotating pressing structure rotates to the maximum angle of 22 degrees, and the pressing head 21 is raised to a distance of 17mm from the upper surface of the base 6.

[0049] Medical alcohol is sprayed through the rectangular opening at the rear of the receiving cavity 12, causing it to adhere to the surface of the first microfiber cloth and the rear half of the surface of the third microfiber cloth. Figure 23As shown, the right hand is opened with the thumb and index finger spread, gripping the device from the bottom. The thumb grips the right outer casing 3, while the middle, ring, and little fingers grip the left outer casing 2. The middle and ring fingers are positioned on either side of the knob 22, with the middle finger touching the knob 22. The index finger is naturally extended. The left hand holds one end of the phone, either the top or bottom, with the back of the phone (the side with the lens) facing down. The other end is pushed into the receiving cavity 12 between the pressing head 21 and the base 6. Because the lower part of the pressing head 21 has a semi-cylindrical curved surface, during the process of pushing the phone in, as... Figure 26 , Figure 27 As shown, the pressing head 21 is slowly lifted, causing the entire rotating pressing structure to rotate upwards around the cylindrical pivot 18. The knob 22 rotates towards the middle finger, squeezing the middle finger and deforming its surface. While slightly pushing the middle finger, it also experiences resistance from the middle finger. The relationship between the knob and the middle finger can be seen in the diagram. Figure 24 As shown. Because this resistance acts on the entire rotating pressing structure through the knob 22, the phone will be pushed up by the pressing head 21 while simultaneously experiencing the pressing force of the pressing head 21. When the phone pushes the pressing head 21 to its maximum possible height, the push-in is complete. After push-in, the phone will be held by the pressing head 21 and the base 6, as shown. Figure 28 , Figure 29 As shown. If the top of the phone is pushed in, the two sides that are clamped are the phone screen and the mirror surface of the lens; if the bottom of the phone is pushed in, the two sides that are clamped are the back of the phone body below the bottom edge of the screen and lens. Because the pressing head 21 applies continuous pressure to the phone during the pushing process, the phone, regardless of its thickness, can be clamped by the pressing head 21 and the base 6 after being pushed in. Since the distance between the left inner wall 4 and the right inner wall 5 is 82mm, which is greater than the width of most different phone models, most phones have a certain amount of room to move in the left and right directions after being pushed in.

[0050] At this point, maintaining a firm grip with your right hand will keep the press head 21 and base 6 clamping the phone in place, without needing to adjust your finger movements or apply extra force. Then, pulling the device back and forth with your right hand will wipe the phone screen, back of the phone, or lens. Pushing it into the top of the phone wipes the screen and lens; pushing it into the bottom wipes the back of the phone below the bottom edge of the screen and lens. Simultaneously, the phone can be wiped against either the left inner wall 4 or the right inner wall 5 to wipe one of the left or right sides. During the wiping process, the phone remains open in the front-back direction of the receiving cavity 12. Figure 24 As shown. The pulling range can be large or small, as long as the phone doesn't come off the clamp. Because the front and back ends of the upper surface of the base 6 are curved, and the curve extends downwards by 5.4mm in the vertical direction, it can protect the top, bottom, and lens of the phone from bumps during pushing in and pulling back and forth. After wiping one end, push in the other end of the phone to wipe, again with the back of the phone facing down.

[0051] After the above wiping process is completed, there will be areas that have not been wiped, including the back of the phone above the bottom edge of the lens, the top and bottom of the phone, such as... Figure 25 As shown, by holding the front end of this utility model and wiping these areas with the rear end of the top shell 1, especially the edge of the rear end, the phone body can be thoroughly cleaned.

[0052] The mobile phones mentioned above refer to candybar smartphones, excluding flip phones and folding phones, and are either unprotected phones or phones with smooth, thin, and regularly shaped cases.
