Description

Technical Field

[0001] The present invention relates to the technical field of computer monitors, and particularly to a dust-proof computer monitor. Background Art

[0002] With the continuous development of technology, computers have become an indispensable tool in people's work and life. As an important output device, the performance and service life of a computer monitor are affected by various factors, among which the accumulation of dust is a problem that cannot be ignored.

[0003] During the operation of a computer monitor, in order to ensure the normal heat dissipation of the electronic components inside the monitor, heat dissipation holes are usually provided on the monitor housing. However, while the heat dissipation holes achieve the heat dissipation function, they also provide a channel for dust to enter the inside of the monitor. After long-term use, a large amount of dust will enter the inside of the monitor through the heat dissipation holes and accumulate on the electronic components and circuit boards inside the monitor. The accumulation of dust will not only affect the heat dissipation effect of the electronic components, causing the temperature of the electronic components to be too high, thereby reducing the performance and service life of the electronic components, but may even cause faults such as short circuits in severe cases, resulting in damage to the monitor.

[0004] Currently, the computer monitors on the market mainly adopt some simple measures for dust prevention, such as setting dust-proof nets at the heat dissipation holes. However, the dust-proof nets can only filter larger dust particles, and for some fine dust particles, the filtering effect of the dust-proof nets is not ideal, and the problem of dust entering the inside of the monitor cannot be fundamentally solved. Moreover, as the use time increases, a large amount of dust will accumulate on the dust-proof nets, and regular cleaning is required. The cleaning process is relatively cumbersome, bringing inconvenience to users. Therefore, it is of great practical significance to develop a dust-proof computer monitor that can effectively solve the problem of dust entering the inside of the monitor and is convenient for cleaning dust. Summary of the Invention

[0005] The purpose of the present invention is to provide a dust-proof computer monitor to solve the deficiencies in dust prevention of existing computer monitors, effectively prevent dust from entering the inside of the monitor, reduce the impact of dust on the electronic components inside the monitor, improve the performance and service life of the monitor, and at the same time facilitate users to clean dust.

[0006] The present invention provides a dust-proof computer monitor, including a monitor housing and a display screen provided on the monitor housing. The monitor housing is provided with heat dissipation holes. The monitor further includes a dust removal component and a dust collection device provided inside the monitor housing. The dust removal component is located below the heat dissipation holes, and the dust collection device is provided below the dust removal component.

[0007] Further, the dust removal assembly includes a discharge electrode, a dust collection plate, a dust brush, a motor, a lead screw, a nut, a bracket, and a dust brush slider. The discharge electrode and the dust collection plate are arranged inside the display housing near the heat dissipation holes. One end of the bracket is arranged at the bottom inside the display housing and is parallel to the dust collection plate. The lead screw is arranged on the bracket. One end of the lead screw is connected to the motor coupling. The nut is arranged on the lead screw. One end of the dust brush is fixedly connected to the nut. The dust brush slider is connected to the nut. The bracket is provided with a chute matching the dust brush slider, and the dust brush slider is arranged in the chute. The dust brush is attached to the dust collection plate. When the motor works, the lead screw rotates, and the nut can drive the dust brush to move up and down on the dust collection plate.

[0008] Further, the dust collection device includes a first dust collection box, a fan, a second dust collection box, and a ventilation pipe. The first dust collection box is arranged at the bottom end of the dust collection plate. One end of the ventilation pipe is communicated with the first dust collection box, and the other end of the ventilation pipe is connected to the air inlet of the fan. The air outlet of the fan is communicated with the second dust collection box.

[0009] Further, a dust removal filter screen is provided on the second dust collection box.

[0010] Further, the dust collection device further includes a dust collection housing and an elastic member. The second dust collection box is provided with a dust collection box slider, and the dust collection housing is provided with a dust collection box chute matching the dust collection box slider. The second dust collection box is movably arranged inside the dust collection housing through the cooperation of the dust collection box slider and the dust collection box chute. One end of the elastic member abuts against the second dust collection box, and the other end of the elastic member abuts against the inner wall of the dust collection housing.

[0011] Further, the dust collection box chute inside the dust collection housing is arranged horizontally, and the dust collection box slider can move left and right in the dust collection box chute.

[0012] When the second dust collection box or the dust removal filter screen is full of dust, due to the increased wind resistance of the fan, the second dust collection box is pushed to move leftward, triggering the first contact to contact the second contact.

[0013] Further, a movable door is provided on the dust collection box chute. When it is necessary to take out the second dust collection box, the movable door is opened, and the dust collection box slider is pulled out at the movable door.

[0014] Further, the dust collection device further includes an alarm lamp, a first contact, and a second contact. The first contact is arranged on the dust collection box slider, and the second contact is arranged inside the dust collection box chute. When the first contact contacts the second contact, the alarm lamp alarms.

[0015] Further, the blower is arranged at the left end inside the dust collection housing, the second dust collection box is arranged at the right end inside the dust collection housing, an air inlet window is provided on one side of the second dust collection box close to the blower, and the dust removal filter screen on the second dust collection box is arranged on the side corresponding to the air inlet window.

When there is a large amount of dust in the second dust collection box or the dust removal filter screen is blocked, under the action of the wind force of the blower, the second dust collection box will move to the left, compressing the elastic member, causing the first contact to contact the second contact, and the alarm lamp will alarm to remind the user to clean the dust.

[0017] Further, the dust removal brush is annular and sleeved on the dust collection plate.

[0018] Using an annular dust removal brush sleeved on the dust collection plate can comprehensively clean all parts of the dust collection plate and improve the cleaning effect.

[0019] Beneficial effects: By setting up the dust removal component in the present invention, the dust entering the interior of the display through the heat dissipation holes is charged by the discharge electrode, and the charged dust is adsorbed by the dust collection plate, thereby effectively preventing the dust from entering the area of the internal electronic components of the display, reducing the influence of the dust on the electronic components, and improving the performance and service life of the display.

[0020] The dust removal brush in the dust removal component can move up and down on the dust collection plate driven by the motor, the lead screw and the nut, cleaning the dust adsorbed on the dust collection plate, ensuring the dust collection effect of the dust collection plate, and the cleaning process has a high degree of automation, without the need for the user to manually clean the dust collection plate, bringing great convenience to the user.

[0021] The dust collection device collects the dust cleaned by the dust removal brush through the first dust collection box, and then uses the blower to transport the dust through the ventilation pipe to the second dust collection box, realizing the centralized collection of the dust, which is convenient for the user to clean the dust.

[0022] A dust removal filter screen is arranged on the second dust collection box, which can further filter the dust transported by the blower and prevent the dust from escaping from the second dust collection box, causing secondary pollution.

[0023] The dust collection housing, elastic member, dust collection box slider, and dust collection box chute provided on the second dust collection box and the dust collection housing in the dust collection device enable the second dust collection box to move within the dust collection housing. When there is a large amount of dust in the second dust collection box or the dust removal filter is clogged, under the action of the wind force of the fan, the second dust collection box will move to the left, compressing the elastic member, causing the first contact to contact the second contact, and the alarm light will alarm to remind the user to clean the dust, with a high degree of intelligence.

This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0030] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] The following is a detailed description of the specific embodiments of the present invention with reference to the accompanying drawings.

[0032] As Figure 1 , Figure 2 shown, when the computer monitor is working, the heat dissipation holes 2 dissipate heat, and the outside air with dust enters the inside of the monitor housing 1 through the heat dissipation holes 2. At this time, the discharge electrode 31 works to charge the entering dust, and the charged dust is adsorbed onto the dust collection plate 32 under the action of the electric field. When it is necessary to clean the dust on the dust collection plate 32, the motor 34 is started. The motor 34 drives the lead screw 35 to rotate. Since the lead nut 36 cooperates with the lead screw 35, and the dust removal brush 33 is fixedly connected to the lead nut 36, and the dust removal brush slider 38 slides in the chute of the bracket 37 to ensure the stability of the movement of the dust removal brush 33. Therefore, when the lead screw 35 rotates, the lead nut 36 drives the dust removal brush 33 to move up and down on the dust collection plate 32, and brushes off the dust adsorbed on the dust collection plate 32.

[0033] The dust brushed off by the dust removal brush 33 falls into the first dust collection box 41. The blower 42 is started, and the blower 42 sucks the dust in the first dust collection box 41 through the ventilation pipe 44 and conveys it to the second dust collection box 43. During this process, when the dust passes through the dust removal filter screen 431 on the second dust collection box 43, the dust is filtered and remains in the second dust collection box 43, and the purified air is discharged. As the dust in the second dust collection box 43 continuously accumulates, when the dust in the second dust collection box 43 is sufficient, or when the dust blocks the dust removal filter screen 431, under the action of the wind force of the blower, the second dust collection box 43 slides leftward in the dust collection box chute 433 through the dust collection box slider 432, compressing the elastic member 46. The first contact 48 on the dust collection box slider 432 contacts the second contact 49 in the dust collection box chute 433. At this time, the alarm lamp 47 lights up to remind the user to clean the dust in the second dust collection box 43. The user can clean the dust inside it and the dust removal filter screen 431 by pulling out the second dust collection box 43. After cleaning, the second dust collection box 43 is reinserted into the dust collection housing 45 to continue the dust collection work.

[0034] The present invention is not limited to the above specific embodiments. Various changes made by those of ordinary skill in the art starting from the above concepts without creative labor fall within the protection scope of the present invention.
