Description

Technical Field

[0001] The invention relates to a screen cleaning device, in particular to a portable screen cleaning device and a mobile phone shell. Background Art

[0002] At present, mobile phones are widely used in our lives, which greatly improves the convenience of our lives. At the same time, it also greatly increases the frequency of our use of mobile phones, resulting in the need to clean and maintain mobile phone screens frequently to avoid affecting normal use.

[0003] A Chinese utility model patent with an existing authorization announcement number of CN208782879U provides a mobile phone case with a screen cleaning function, which includes a shell and a cleaning bracket. The inner side of the shell is a accommodating space. The shell includes two oppositely arranged side edges and a partition that divides the accommodating space into a mobile phone accommodating cavity and a cleaning cavity. Slide grooves are provided on the two side edges, and the two ends of the cleaning bracket slide in the two slide grooves respectively. A cleaning sheet is detachably installed on the inner side of the cleaning bracket.

[0004] When the mobile phone screen is stained with dust or other stains, the user can slide the cleaning bracket to let the cleaning sheet slide across the screen to achieve the purpose of cleaning.

[0005] However, the above technical solution has the following problems: since the screens of mobile phones or other mobile devices usually use glass outer screens, when the cleaning sheet passes across the screen, it will drive sand or other hard small particles across the screen, causing scratches on the screen, so it needs to be improved. Summary of the invention

[0006] To this end, the purpose of the present invention is to provide a portable screen cleaning device and a mobile phone case to solve the problem that when the above-mentioned cleaning sheet slides across the screen, it drives sand or other hard small particles across the screen, causing scratches on the screen.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions:

[0008] A portable screen cleaning device comprises a hollow semi-cylindrical containing shell, a rotating shaft rotatably connected to the containing shell, and a brush wheel sleeved outside the rotating shaft, wherein the brush wheel portion is located outside the containing shell; there is a gap between the outer wall of the brush wheel and the inner wall of the containing shell, and a protective device is provided in the gap, with both ends rotatably connected to the containing shell.

[0009] By adopting the above technical solution, when the screen of a user's mobile phone or other mobile device needs to be cleaned, the user can hold the housing shell, use the part of the brush wheel outside the housing shell to press against the screen, and roll the brush wheel to achieve rolling cleaning of the surface of the mobile phone screen. In this way, even if there are hard particles on the screen or on the brush wheel, they will be adsorbed on the brush wheel when the brush wheel rolls, thereby avoiding the problem of scratching the screen surface by hard particles due to sliding cleaning;

[0010] In addition, the protective device can protect the part of the brush wheel located outside the containing shell when the cleaning device is not in use, thereby preventing the brush wheel from absorbing dust in the air when not in operation.

[0011] Preferably, the protective device is a hollow semi-cylindrical protective shell.

[0012] By adopting the above technical solution, since the containing shell is also in a hollow semi-cylindrical shape, the protective device adopts a hollow semi-cylindrical protective shell with a shape similar to the containing shell, so as to protect the part of the brush wheel located outside the containing shell.

[0013] Preferably, one end of the protective shell protrudes outward to form a first protrusion, the inner wall of one end of the accommodating shell is provided with a first groove which is plugged into and cooperates with the first protrusion, and the other end of the protective shell is provided with a knob rotatably connected to the accommodating shell.

[0014] By adopting the above technical solution, the plug-in cooperation between the first protrusion and the first groove can make the protective shell rotatably fixed on the protective shell, and the other end can achieve a fixed relationship with the protective shell through a knob.

[0015] Preferably, a first rotating hole is formed at one end of the accommodating shell away from the first groove, a second rotating hole is formed at one end of the protective shell away from the first protrusion, and a positioning groove is formed in communication with the second rotating hole. The knob includes a screwing portion, a first rotating cylinder rotatably connected to the first rotating hole, and a second rotating cylinder rotatably connected to the second rotating hole. The diameter of the second rotating cylinder is smaller than that of the first rotating cylinder, and the first rotating cylinder extends to form a positioning block that is plugged into and fits with the positioning groove.

[0016] By adopting the above technical solution, the first rotating drum and the second rotating drum are rotatably connected to the first rotating hole and the second rotating hole respectively, so that the knob can simultaneously realize a rotational connection relationship with the containing shell and the protective shell. Under the snap-fitting relationship between the positioning block and the positioning groove, the knob can simultaneously drive the protective shell to rotate when it is rotated. Therefore, the user can hold the containing shell and turn the knob to rotate the protective shell, thereby exposing the brush wheel.

[0017] Preferably, the positioning block extends into the interior of the protective shell and is provided with a barb block.

[0018] By adopting the above technical solution, the barb block hooks the inner wall of the protective shell, so that the knob will not fall off when it is rotated. In addition, the barb block can also achieve the function of fixing one end of the protective shell.

[0019] Preferably, the protective shell has an inner wall of one end of the first protrusion with a second groove, one end of the rotating shaft is provided with a second protrusion plug-fitting with the second groove, and the other end is supported on the knob.

[0020] By adopting the above technical solution, the plug-in fitting relationship between the second protrusion and the second groove can rotatably fix one end of the rotating shaft to the protective shell, and the other end of the rotating shaft can be supported by the knob, and the combination of the two can achieve the function of fixing the rotating shaft.

[0021] Preferably, the knob is provided with an anti-slip rubber strip.

[0022] By adopting the above technical solution, the user can turn the knob more conveniently.

[0023] Preferably, the inner side wall of the accommodating shell is provided with two slots symmetrically arranged along its axis, and the outer side wall of the protective shell is provided with a block engaged with the slots.

[0024] By adopting the above technical solution, when the user rotates the card block from one card slot to another card slot, the two states of the brush wheel being exposed and protected can be realized. On the other hand, since one end of the brush wheel is supported by a knob, when the brush wheel rolls, the knob will rotate slightly, thereby driving the protective shell to rotate, and the card-joint force between the card slot and the card block can prevent the protective shell from rotating, making it convenient for users to use.

[0025] Preferably, the brush wheel is made of silicone material or TPR viscose material.

[0026] By adopting the above technical solution, the silicone material or the TPR adhesive material has good adsorption capacity and can effectively absorb dust on the screen.

[0027] A mobile phone case comprises a shell body, wherein the shell body is divided into a small area and a large area by a partition, a mobile phone is placed in the large area, and a cleaning device is detachably clamped in the small area.

[0028] By adopting the above technical solution, the cleaning device can be detachably fixed on the mobile phone case, allowing the user to remove the cleaning device from the mobile phone case and perform screen cleaning when the cleaning device is needed. When the cleaning device is not needed, the cleaning device can be placed on the mobile phone case for easy carrying.

[0029] The portable screen cleaning device and mobile phone case provided by the present invention have the following advantages:

[0030] 1. It can avoid the problem of hard particles scratching the screen surface during sliding cleaning;

[0031] 2. The protective device can protect the part of the brush wheel outside the housing when the cleaning device is not in use, preventing the brush wheel from absorbing dust in the air when not in operation;

[0032] 3. The cleaning device can be detachably fixed on the mobile phone case, so that the user can remove the cleaning device from the mobile phone case and perform screen cleaning when the cleaning device is needed. When the cleaning device is not needed, the cleaning device can be placed on the mobile phone case for easy carrying. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0044] A portable screen cleaning device, such as Figure 1 and Figure 2 As shown, it includes a hollow semi-cylindrical containing shell 1, a rotating shaft 2 rotatably connected to the containing shell 1, and a brush wheel 3 sleeved on the outside of the rotating shaft 2, and the brush wheel 3 is partially located outside the containing shell 1; there is a gap between the outer wall of the brush wheel 3 and the inner wall of the containing shell 1, and a protective device is provided in the gap, with both ends rotatably connected to the containing shell 1.

[0045] Specific working principle: when the screen of a user's mobile phone or other mobile device needs to be cleaned, the user can hold the containing shell 1, and use the part of the brush wheel 3 outside the containing shell 1 to press against the screen, and roll the brush wheel 3 to achieve rolling cleaning of the surface of the mobile phone screen. In this way, even if there are hard particles on the screen or on the brush wheel 3, they will be adsorbed on the brush wheel 3 when the brush wheel 3 rolls, thereby avoiding the problem of hard particles scratching the screen surface during sliding cleaning; in addition, the protective device can protect the part of the brush wheel 3 outside the containing shell 1 when the cleaning device is not in use, to prevent the brush wheel 3 from absorbing dust in the air when it is not working.

[0046] The protective device is a hollow semi-cylindrical protective shell 4; since the containing shell 1 is also hollow semi-cylindrical, the protective device adopts a hollow semi-cylindrical protective shell 4 with a shape similar to the containing shell 1, which can protect the part of the brush wheel 3 located outside the containing shell 1.

[0047] The brush wheel 3 is made of silicone material or TPR adhesive material; silicone material or TPR adhesive material has good adsorption capacity and can effectively absorb dust on the screen.

[0048] like Figures 3 to 5As shown, one end of the protective shell 4 protrudes outward to form a first protrusion 5, and the inner wall of one end of the accommodating shell 1 is provided with a first groove 6 which is plugged into and matched with the first protrusion 5, and the other end of the protective shell 4 is provided with a knob 7 which is rotatably connected to the accommodating shell 1; the plug-in cooperation between the first protrusion 5 and the first groove 6 can make the protective shell 4 rotatably fixed on the protective shell 4, and the other end thereof can be fixed with the protective shell 4 through the knob 7.

[0049] The protective shell 4 has a first protrusion 5, and the inner wall of one end thereof is provided with a second groove 8. One end of the rotating shaft 2 is provided with a second protrusion 9 which is plug-fitted with the second groove 8, and the other end thereof is supported on the knob 7. The plug-fitting relationship between the second protrusion 9 and the second groove 8 can rotatably fix one end of the rotating shaft 2 on the protective shell 4, and the other end of the rotating shaft 2 can be supported by the knob 7. The combination of the two can achieve the function of fixing the rotating shaft 2.

[0050] The knob 7 is provided with an anti-slip rubber strip 10 , which enables the user to turn the knob 7 more conveniently.

[0051] A first rotating hole 11 is formed at one end of the accommodating shell 1 away from the first groove 6, a second rotating hole 12 is formed at one end of the protective shell 4 away from the first protrusion 5, and a positioning groove 13 is formed in communication with the second rotating hole 12. The knob 7 includes a screwing portion 14, a first rotating cylinder 15 rotatably connected to the first rotating hole 11, and a second rotating cylinder 16 rotatably connected to the second rotating hole 12. The diameter of the second rotating cylinder 16 is smaller than that of the first rotating cylinder 15. The first rotating cylinder 15 extends to form a positioning block 17 that is plugged into and fits with the positioning groove 13.

[0052] The first rotating drum 15 and the second rotating drum 16 are rotatably connected to the first rotating hole 11 and the second rotating hole 12 respectively, so that the knob 7 is rotatably connected with the containing shell 1 and the protective shell 4 at the same time. Under the snap-fitting relationship between the positioning block 17 and the positioning groove 13, the knob 7 can drive the protective shell 4 to rotate when it is rotated. Therefore, the user can hold the containing shell 1 and rotate the knob 7 to rotate the protective shell 4, thereby leaking the brush wheel 3.

[0053] The positioning block 17 extends to the inside of the protective shell 4 and is provided with a barb block 18; the barb block 18 hooks the inner wall of the protective shell 4 so that the knob 7 will not fall off when rotating. In addition, the barb block 18 can also fix one end of the protective shell 4.

[0054] like Figure 6 and Figure 7As shown, the inner wall of the accommodating shell 1 is symmetrically provided with two slots 19 along its axis, and the outer wall of the protective shell 4 is provided with a block 20 that is engaged with the slot 19; when the user rotates the block 20 from one slot 19 to another slot 19, the two states of the brush wheel 3 being exposed and protected can be realized. On the other hand, since one end of the brush wheel 3 is supported by the knob 7, when the brush wheel 3 rolls, the knob 7 will rotate slightly, thereby driving the protective shell 4 to rotate, and the engaging force between the slot 19 and the block 20 can prevent the protective shell 4 from rotating, making it convenient for users to use.

[0055] The present invention also provides a mobile phone case (not shown in the figure), which includes a shell, the shell is divided into a small area and a large area by a partition, the mobile phone is placed in the large area, and the above-mentioned cleaning device is detachably connected to the small area. The cleaning device can be detachably fixed to the mobile phone shell, so that when the user needs to use the cleaning device, the cleaning device can be removed from the mobile phone shell and the screen can be cleaned. When the cleaning device is not needed, the cleaning device can be placed on the mobile phone shell for easy carrying.

[0056] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
