Description

Technical Field

[0001] The invention relates to the technical field of voice control of display screens, in particular to a voice control terminal for a self-cleaning display screen. Background Art

[0002] With the continuous advancement of science and technology, various intelligent display devices, such as smart TVs, smart phones, tablet computers, medical terminals, etc., are constantly emerging. The functions of these devices are becoming increasingly powerful, and users have higher and higher requirements for the convenience and flexibility of their operation. At present, the commonly used interface control methods of intelligent display devices include control through control devices, touch control, etc., but in the case of control device failure, touch screen damage or user's hands are inconvenient to operate, these traditional control methods will be limited and cannot meet the user's normal control needs for the device, which prompts people to seek more convenient and flexible control methods; In modern technology products, user experience is increasingly valued. Voice control, as a natural and intuitive way of interaction, enables users to operate devices more conveniently and quickly, thus improving the user experience. Therefore, more and more device manufacturers and developers are beginning to apply voice control technology to display terminals. The existing voice control terminal for display screens still has the following technical problems when in use, such as: 1. During the use of the existing voice control terminal, due to the electrostatic adsorption, it will absorb dust. In order to prevent the dust from affecting the normal operation of its electronic components, a filter is generally set on the outside. However, during long-term use, a lot of dust will also accumulate on the filter. If the dust on the filter is not cleaned in time, it will not only affect the heat dissipation of the electronic components inside the voice control terminal, thereby affecting its normal operation, but also cause the human voice to be unable to be accurately recognized by the voice control terminal, thereby making the voice control terminal difficult to use; 2. When cleaning the filter on the voice control terminal using conventional methods, dust is easily blown up, causing the person wiping to inhale the dust, which can cause health problems; Therefore, a self-cleaning display screen voice control terminal is needed to solve the above problems. Summary of the invention

[0003] The object of the present invention is to provide a self-cleaning voice control terminal for a display screen, so as to solve the problem in the above background technology that the existing voice control terminal for a display screen is not provided with a self-cleaning mechanism and manual cleaning will cause dust to fly.

[0004] To achieve the above object, the present invention provides the following technical solutions: A self-cleaning voice control terminal for a display screen includes a voice control module, a cleaning component, a dust removal component and a dust reduction component, and is characterized in that: a filter is installed on the voice control module, and an electric control component is arranged on the outer side of the voice control module; a cleaning component is arranged inside the voice control module for cleaning dust adsorbed on the surface of the filter; a dust removal component is also arranged on the cleaning component, and the dust removal component is used to remove dust on the cleaning component; the dust removal component is connected to the cleaning component through the dust reduction component, and is used to prevent dust from flying when the dust removal component is removing dust.

[0005] Furthermore, the cleaning component includes a motor frame, a servo motor, a displacement groove, a guide groove, an installation frame, a strip hole, a wiping brush head, a screw rod, a rubber sheet, a shaft tube, a dust removal brush head, a sliding groove, a guide block, a pressing head, a displacement block, a limit block, a follower groove and a spring. The displacement groove and the guide groove are arranged on the upper and lower sides of the voice control module, and the guide groove is arranged in front of the displacement groove. The bearing in the upper displacement groove is connected with a screw rod, and the bearing at one end of the screw rod passes through the outside of the voice control module. The end of the screw rod that passes through the outside of the voice control module is coaxially connected to the shaft end of the servo motor, and the servo motor is installed on the outer surface of the voice control module through the motor frame. The screw rod passes through 3 displacement blocks, and the screw rod is threadedly connected to the middle displacement block. Three displacement blocks are arranged on the upper and lower surfaces of the installation frame, and the displacement blocks are slidably connected to the corresponding displacement grooves. The upper and lower surfaces of the installation frame The two cams are connected by a plurality of guide wheels, each of which is connected to a pair of guide wheels, and the two guide wheels are connected by a plurality of guide wheels, each of which is connected to a pair of guide wheels.

[0006] By adopting the above technical scheme, the operation of the servo motor can drive the screw to rotate, and then the displacement block drives the installation frame to move, so that the wiping brush head on the installation frame can wipe the filter, thereby removing the dust accumulated on the surface of the filter. While the installation frame is moving, the guide block will move in the guide groove. When the guide block gradually moves to the end of the guide groove, the shaft end of the shaft tube will slide in the sliding groove, and the pressing head will be pressed at the same time, and then slide in the follower groove through the limit block, driving the shaft tube to rotate 180°, so that the positions of the dust removal brush head and the wiping brush head are swapped. During the reciprocating movement of the installation frame, the dust removal brush head and the wiping brush head can wipe the filter alternately, which not only reduces the degree of dust flying, but also improves the effect of wiping the filter.

[0007] Furthermore, the follower groove is a groove body connected end to end, consisting of two sections of inclined arcs and two sections of strip grooves.

[0008] By adopting the above technical solution, when the installation frame moves horizontally to the positions of the two ends of the displacement groove, the shaft end of the shaft tube can slide in the sliding groove through the follower groove, thereby facilitating the position swapping of the dust removal brush head and the wiping brush head.

[0009] Furthermore, the guide block is an open square structure, and is connected to the corresponding shaft tube axial end by a coaxial bearing, the end of the pressing head extending into the guide block is also a square structure, and the structural shape of the lower end of the pressing head matches the structural shape of the inner side of the guide block.

[0010] By adopting the above technical solution, the rotation of the pressing head can be limited by the guide block, so that the pressing head can drive the shaft end of the shaft tube to rotate when moving in the vertical direction.

[0011] Furthermore, the two ends of the guide groove are symmetrically inclined, and the middle of the guide groove is arranged parallel to the displacement groove. The longitudinal lengths of the displacement groove and the guide groove are the same, and the partial depths at both ends of the guide groove gradually become shallower, and the shallowest depth of the guide groove is not less than the height of the guide block.

[0012] By adopting the above technical solution, when the guide block slides to the two ends of the guide groove, the shaft end of the shaft tube will slide on the sliding groove.

[0013] Furthermore, the wiping brush head is a hollow structure, and the outer end of the wiping brush head is wrapped with a cloth part for wiping dust.

[0014] By adopting the above technical solution, the wiping brush head with a hollow structure can allow air containing moisture to contact the cloth part wrapped with wiping dust, thereby wetting the cloth, thereby improving the wiping effect.

[0015] Furthermore, the dust removal assembly includes a twisted rod, a slider, a slide groove, a support tube, a ratchet pawl assembly, a transmission plate, a transmission belt and a dusting brush. The slide groove is arranged on the left and right sides inside the voice control module, and a slider is slidably connected in each slide groove. The slider is arranged at both ends of the twisted rod, and the twisted rod thread penetrates the support tube. The bearings at both ends of the support tube are connected to the inner side of the mounting frame, and a transmission plate is provided on the outer side of the support tube. The two ends of the transmission plate are connected to the corresponding outer bearings of the support tube, and the middle part of the transmission plate is connected to the corresponding outer side of the support tube through the ratchet pawl assembly. The two transmission plates are connected by a transmission belt, and a dusting brush is distributed on the outer side of the transmission belt.

[0016] By adopting the above technical solution, during the reciprocating movement of the installation frame, the transmission belt can rotate only in one direction through the twisted rod, support tube and ratchet pawl assembly, so that after the dust removal brush head has brushed off the dust, it will be cleaned by the dust brush on the transmission belt, thereby reducing the dust contained in the dust removal brush head, facilitating the subsequent use of the dust removal brush head, the dust removal effect is improved, and the frequency of replacing the cloth part of the dust removal brush head is reduced.

[0017] Furthermore, the length of the dusting brush is not less than the minimum distance between the transmission belt and the dust removal brush head, and the structural shape of the dust removal brush head is the same as the structural shape of the wiping brush head.

[0018] By adopting the above technical solution, the dust brush can be easily contacted with the dust removal brush head, thereby facilitating the removal of dust adsorbed on the dust removal brush head.

[0019] Furthermore, the dust reduction assembly includes a drainage hole, a water inlet hole, a piston tube, a one-way air inlet hole, a water storage tank, a one-way air inlet pipe, a piston rod, a spring 1, an exhaust pipe and a cam. The water storage tank is arranged inside the installation frame, and the water storage tank passes through the transmission belt arrangement. The upper and lower parts of the water storage tank are respectively provided with a water inlet hole and a drainage hole, and the water inlet hole and the drainage hole both pass through the installation frame arrangement, and the water inlet hole and the drainage hole are covered with a cover. Piston tubes are provided on both sides of the upper and lower ends of the water storage tank, and the outer end of the piston tube is connected with a piston rod, a spring 1 is provided between the inner end of the piston rod and the outer end of the piston tube, and one-way air inlet holes are evenly distributed on the piston tube, the piston tube is connected with the water storage tank through the one-way air inlet pipe, and the upper part of the water storage tank is connected with the shaft tube through the exhaust pipe, and the shaft tube is connected with the wiping brush head through evenly distributed through holes, and each outer end of the piston rod corresponds to a cam, and the cam key is connected to the corresponding outer side of the support tube.

[0020] By adopting the above technical scheme, the cam can repeatedly squeeze the piston rod through the rotation of the support tube, so that the gas in the piston tube is squeezed into the water tank. Through the one-way air inlet hole and spring 1, the dust removed by the dust removal component can enter the piston tube with the air, and then enter the water tank through the one-way air inlet pipe. Subsequently, the dust is absorbed by the water, and the air carrying moisture will enter the shaft tube through the exhaust pipe, and then enter the wiping brush head to moisten the cloth, thereby improving the effect of the cloth wiping the filter.

[0021] Furthermore, the inner bottom end of the water tank is an inclined slope, and the lowest end of the slope is flush with the lowest position of the drainage hole, and the end of the one-way air inlet pipe extending into the water tank is close to the lower end of the water tank.

[0022] The adoption of the technical solution can facilitate the discharge of sewage that absorbs dust.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: the self-cleaning display screen voice control terminal can automatically clean the filter on the voice control terminal through voice control, thereby preventing dust from accumulating on the filter and affecting the reception of human voice, and in the process of cleaning the filter, the degree of dust flying can be reduced, which not only avoids dust pollution of the environment, but also avoids health problems caused by manual cleaning: 1. The cleaning component can brush away the dust accumulated on the filter surface, which not only improves heat dissipation and prevents the voice control terminal from not being able to operate normally due to poor heat dissipation, but also facilitates the transmission of human voice to the voice control terminal, thereby improving the accuracy of voice recognition. In addition, the alternating use of the wiping brush head and the dust removal brush head can improve the effect of removing dust from the filter. 2. The dust removal component can remove the dust adsorbed on the dust removal brush head, thereby improving the cleaning effect of the dust removal brush head when it is used again, and reducing the frequency of replacing the cloth on the dust removal brush head; 3. Through the action of the dust reduction component, the air carrying dust in the installation frame can be absorbed, and the air with dust removed can carry moisture into the wiping brush head and contact the cloth part on the wiping brush head, thereby wetting the cloth, which is beneficial to improve the cleaning effect of the filter after the wiping brush head wipes and removes dust.
