Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the disclosed embodiments are merely exemplary of the invention, and are not intended to be exhaustive or exhaustive. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Referring to fig. 1 to 4, an embodiment of the invention discloses a self-cleaning device, which can be configured in an electronic apparatus. The disclosed self-cleaning function assembly includes a motion module 200, a function module 800, and a cleaning brush 300.
The motion module 200 is generally mounted to the housing 100 of the electronic device, and the motion module 200 provides a mounting base for the function module 800. In a specific working process, the moving module 200 moves to drive the functional module 800 to move together, thereby adjusting the position of the functional module 800.
The function module 800 is disposed on the motion module 200, and under a normal condition, the function module 800 is fixedly connected to the motion module 200, so as to achieve a synchronous motion of the two modules. In the embodiment of the present invention, the function module 800 may pass through the first position during the process of moving with the motion module 200.
The cleaning brush 300 is a cleaning body of the self-cleaning functional assembly, when the functional module 800 is located at the first position, the cleaning brush 300 contacts with the functional module 800, and the movement module 200 can move, so that the functional module 800 can be driven to move relative to the cleaning brush 300, and finally, the surface dust of the functional module 800 is brushed away through the friction generated between the cleaning brush and the functional module. In a general case, the cleaning brush 300 may be a brush having a good cleaning effect. Of course, the cleaning brush 300 may also be another structure capable of removing dust on the surface of the functional module 800 by contact, for example, the cleaning brush 300 may also be a brush body made of cotton cloth, and the embodiment of the present invention is not limited to the specific type of the cleaning brush 300.
When the self-cleaning functional assembly disclosed by the embodiment of the invention works, the functional module 800 can move along with the movement module 200 and further can be in contact with the cleaning brush 300 when passing through the first position, and the functional module 800 and the cleaning brush 300 can move relatively, so that dust on the surface of the functional module 800 can be cleaned by friction between the functional module 800 and the cleaning brush 300, and under the condition, a user can clean dust on the functional module 800 by controlling the movement module 200 to move in the using process without repair. This can undoubtedly avoid the problem of inconvenient use for users due to repair, and meanwhile, the self-cleaning functional assembly disclosed in the embodiment of the invention can realize self-cleaning of the functional module 800, so that the ash cleaning cost spent by users can be reduced, and the use cost of users can be further reduced.
In an alternative, the cleaning brush 300 may be rotatably disposed, and in particular, the cleaning brush 300 may be rotatably disposed on the housing 100. The contact between the cleaning brush 300 and the function module 800 may be rolling contact. In this case, the rolling contact can prevent the friction between the cleaning brush 300 and the functional module 800 from being excessive, and thus can prevent the functional module 800 from being worn due to the excessive friction.
In the embodiment of the present invention, the rotation of the cleaning brush 300 can be achieved through manual operation, for example, a manual operation knob can be disposed on the housing 100 of the electronic device, the manual operation knob and the cleaning brush 300 are coaxially disposed, and a user can operate the manual operation knob to rotate during use, so as to achieve the rotation of the cleaning brush 300, and achieve the purpose of cleaning the surface of the functional module 800 for dust collection.
In order to further facilitate the use of the user, optionally, the self-cleaning function assembly disclosed in the embodiment of the present invention may further include a first driving mechanism 400, the first driving mechanism 400 is connected to the cleaning brush 300, and the first driving mechanism 400 may drive the cleaning brush 300 to rotate. The cleaning brush 300 is rotated by the driving of the first driving mechanism 400. Meanwhile, the first driving mechanism 400 can more flexibly adjust the rotation speed of the cleaning brush 300.
The structure of the first driving mechanism 400 may be various. For example, the first driving mechanism 400 may include a first driving motor, and the first driving motor may be directly or indirectly connected to the cleaning brush 300 through a transmission mechanism. In order to more flexibly adjust the rotation speed of the cleaning brush 300, the first driving motor may be drivingly connected to the cleaning brush 300 through a speed reducer.
In the embodiment of the present invention, the rotation speed of the cleaning brush 300 may be greater than the moving speed of the movement module 200, so that the cleaning brush 300 and the function module 800 can generate relatively obvious relative movement, thereby improving the cleaning force of the cleaning brush 300 and finally improving the ash removal effect. The rotational speed of the cleaning brush 300 refers to the linear speed of the portion of the cleaning brush 300 that is in contact with the surface of the function module 800.
The self-cleaning functional assembly disclosed in the embodiment of the present invention may further include a dust collecting device 500, the dust collecting device 500 may include a dust container 510, the dust container 510 has a dust collecting space and a dust interface 511, the dust interface 511 is communicated with the dust collecting space, and the dust interface 511 is disposed opposite to the cleaning brush 300. In a specific ash removing process, dust brushed by the cleaning brush 300 falls into a dust collecting space through the dust interface 511 under the action of gravity, so that the dust is collected, and subsequent centralized treatment is facilitated. The dust collecting space can effectively collect dust, and the dust can be prevented from falling into the electronic equipment.
In a further aspect, the dust collecting apparatus 500 disclosed in the embodiment of the present invention may further include a scraper 520, wherein the scraper 520 is disposed on the dust container 510, and the scraper 520 is in sliding contact with the cleaning brush 300. In a specific working process, the scraper 520 can scrape off dust on the cleaning brush 300, so that the cleaned dust falls into the dust collecting space through the dust interface 511 as much as possible, and the dust is collected better. Specifically, the projection of the contact part of the scraper 520 and the cleaning brush 300 in the moving direction of the motion module 200 is located in the dust interface 511, so that the dust scraped off by each part of the scraper 520 can enter the dust collecting space through the dust interface 511 under the action of gravity.
Alternatively, the scraper 520 may be an elastic plate-shaped member, and the scraper 520 abuts on the cleaning brush 300. The elastic plate-shaped member can be elastically deformed, and thus, the occurrence of a seizure phenomenon with the cleaning brush 300 can be prevented. Specifically, the scraper 520 may be a rubber plate-shaped member.
The dust collecting device 500 disclosed in the embodiment of the present invention may further include a dust conveying mechanism 530, and the dust conveying mechanism 530 may convey the dust collected in the dust collecting space, so as to prevent excessive dust from being accumulated in the dust collecting space. The dust conveying mechanism 530 may be various in kind as long as it can discharge the dust collected in the dust collecting space. In a general case, the dust container 510 has a dust discharge port through which dust conveyed by the dust conveying mechanism 530 can be finally discharged.
In an alternative embodiment, the dust conveying mechanism 530 may include a second driving mechanism 531 and a dust push plug 532, and the second driving mechanism 531 is connected to the dust push plug 532. The dust push plug 532 is movably disposed in the dust accommodating device 510, and the second driving mechanism 531 drives the dust push plug 532 to move in the dust collecting space. In a specific working process, dust is accumulated in the dust collecting space, the second driving mechanism 531 drives the dust push plug 532 to move, and the dust push plug 532 pushes away the dust in the dust collecting space, so that the dust can be prevented from being accumulated locally.
In a further aspect, the dust push plug 532 may be a flexible plug that can better conform to the inner wall of the dust collection space to better drain away the dust. Specifically, the dust push plug 532 may be a rubber plug.
In the present embodiment, the dust container 510 may have various structures, and optionally, the dust container 510 may include a first tube segment 510a and a second tube segment 510b, a first end of the second tube segment 510b is communicated with the first tube segment 510a, and a port of a second end of the second tube segment 510b is a dust discharge port. The lumen of the first tube section 510a is a dust collecting space. The dust connection port 511 is opened in the first pipe section 510a, the dust push plug 532 is movably disposed in the first pipe section 510a, and the second driving mechanism 531 drives the dust push plug 532 to move along the first pipe section 510a, so that the dust collected in the dust collecting space can be discharged through the dust discharge port of the second pipe section 510 b. In a normal case, the housing 100 of the electronic device may be opened with a second through hole, and the second through hole is communicated with the dust discharging port, so that dust can be discharged out of the housing 100 of the electronic device through the second through hole.
Alternatively, the axis of the first tube section 510a and the axis of the second tube section 510b may intersect or be non-coplanar, in which case the first tube section 510a and the second tube section 510b run differently, thus enabling a more flexible arrangement, avoiding the problem of the dust holding means 510 being too long to be easily arranged in the housing 100 of the electronic device. At the same time, the first tube section 510a and the second tube section 510b are not in a straight line, which can certainly push the dust in the second tube section 510b not to easily flow back, which is more favorable for the dust to be discharged.
In an embodiment of the present invention, the function module 800 may include at least one of a camera 810, an acoustic device (e.g., a microphone) 820, and a flash 830. The acoustic device 820 is provided with a sound guide hole, the flash lamp 830 comprises a flash lampshade, the camera 810 comprises a camera lens, and when the functional module 800 is in the first position, the sound guide hole, the flash lampshade or the camera lens is in contact with the cleaning brush 300, so that dust collection on the sound guide hole, the flash lampshade or the camera lens is cleaned. Of course, the functional module 800 may also include other types of functional devices, and the embodiment of the invention does not limit the specific type of the functional module 800.
Based on the self-cleaning functional assembly disclosed by the embodiment of the invention, the embodiment of the invention discloses electronic equipment, and the disclosed electronic equipment comprises the self-cleaning functional assembly disclosed by the embodiment.
In a general case, the electronic device includes a housing 100, the housing 100 is a base member of the electronic device, and the housing 100 can provide a mounting base for other components of the electronic device. In the embodiment of the present invention, the motion module 200 and the cleaning brush 300 are disposed on the housing 100. Specifically, the housing 100 has an inner cavity and a first through hole, the first through hole is connected to the inner cavity, and the through hole is used for the movement module 200 to pass through, so as to switch the position of the movement module 200 between the outside of the housing 100 and the inside of the housing 100. In a general case, the casing 100 includes a middle frame, and the first through hole may be opened in the middle frame, and of course, the first through hole may also be opened in other positions of the casing 100, and the specific opening position of the through hole on the casing 100 is not limited in the embodiments of the present invention.
The motion module 200 is movably disposed on the housing 100, and the motion module 200 can move relative to the housing 100. In the embodiment of the present invention, the motion module 200 can be retracted into the inner cavity or at least partially extended out of the housing 100 through the through hole, and the function module 800 can work when the motion module 200 is at least partially extended out of the housing 100. With the motion module 200 retracted into the internal cavity, the motion module 200 and the function module 800 can be concealed within the housing 100. For example, the function module 800 includes a camera 810, and when a user needs to shoot, the motion module 200 drives the function module 800 to extend out of the housing 100, so that the camera 810 shoots an image outside the housing 100. After the shooting is completed, the function module 800 retracts into the housing 100 along with the motion module 200, thereby realizing the hiding in the housing 100.
The electronic device disclosed in the embodiment of the present invention may further include a control device 600, and in a case that the motion module 200 is retracted into the housing 100 or at least partially extended out of the housing 100, the control device 600 may sequentially control the dust pushing plug 532 to move toward the direction close to the second pipe section 510b and move away from the second pipe section 510b, so that the second driving mechanism 531 may drive the dust pushing plug 532 to push away the dust and then reset, so as to prepare for the next driving. Specifically, the control device 600 may be in control connection with the second driving mechanism 531 through the data line 700. Of course, the control device 600 may be connected to the first driving mechanism 400 through the data line 700 to control the first driving mechanism 400.
The electronic device disclosed in the embodiment of the present invention may be a mobile phone, a tablet computer, an electronic book reader, a game machine, a wearable device (e.g., a smart watch), or the like, and may also be other types of devices.
