Description

Technical Field

[0001] The present invention relates to the technical field of dust collecting devices, and in particular to a resilient dust collecting scraper device for dust collecting equipment and the dust collecting equipment. Background Art

[0002] With the continuous development of society, vacuum cleaners are widely used in all walks of life. The working principle of vacuum cleaners is to use an electric motor to drive the blades to rotate at high speed, generate negative air pressure in the sealed shell, and absorb dust.

[0003] The part of the vacuum cleaner that actually performs the vacuuming function generally uses a dust scraper. The normal use of the dust scraper is inseparable from a stable bracket device. The dust scraper device installed in front of the existing vacuum cleaner is simple in design and has no autonomous protection function. It mainly relies on manual visual obstacle avoidance. During the movement of the vacuum cleaner, the dust scraper device is prone to collision, causing damage to the equipment. Therefore, the current dust scraper device cannot be used on unmanned vacuum trucks.

[0004] Based on the above problems, we have designed a resilient dust scraper device for vacuum cleaners. After a hard collision, the dust scraper device can autonomously transmit a trigger signal to the vacuum cleaner, causing the vacuum cleaner to cut off power and stop running, thereby ensuring the vacuum cleaner. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a resilient dust scraper device for dust collection equipment.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A reboundable dust scraper device for a dust suction device, wherein the dust suction device is provided with a dust suction device control system, and the dust scraper device comprises a dust scraper body, a dust scraper body downward movement driving mechanism, a front anti-collision plate and a rebound telescopic trigger mechanism;

[0008] The front anti-collision plate is hinged to the main body of the vacuum cleaner, and is arranged in a front-to-back offset manner with the main body of the vacuum cleaner, and can perform a flipping movement towards or away from the main body of the vacuum cleaner;

[0009] The driving mechanism for moving the dust scraper body downward is installed on the other side of the dust scraper body different from the front anti-collision plate, connected to the dust collecting device, and connected to the control system of the dust collecting device, and can drive the dust scraper body to move up and down relative to the dust collecting position;

[0010] The rebound-type telescopic trigger mechanism is jointly arranged on the downward driving mechanism of the vacuum cleaner main body and the vacuum cleaner main body, and is equipped with a contact switch connected to the vacuum cleaner control system;

[0011] When the front anti-collision plate is hit and the dust suction scraper body stops moving, the rebound type telescopic trigger mechanism can perform a telescopic movement to trigger the contact switch.

[0012] After the vacuum cleaner in the present invention receives the vacuum cleaner command from the remote control, the vacuum cleaner is started and runs normally, driving the entire vacuum cleaner device to move. After running to the vacuum cleaner position, since the vacuum cleaner main body is initially in a higher position, the vacuum cleaner control system controls the vacuum cleaner main body downward movement driving mechanism to lower the vacuum cleaner main body to perform the vacuum cleaner operation.

[0013] Furthermore, the downward movement driving mechanism of the vacuum cleaner body includes a movable support frame and a fixed support frame;

[0014] One end of the movable support frame is provided with a support frame connector, which is detachably connected to the dust suction scraper body through the support frame connector, and the other end is fixedly connected to the fixed bracket;

[0015] The fixed bracket is provided with a lifting connector port for connecting the push rod motor.

[0016] Furthermore, a front anti-collision plate connector is provided on one side of the front anti-collision plate, and the anti-collision plate connector is detachably connected to the support frame connector.

[0017] Furthermore, a strip-shaped mounting hole is formed on the support frame connector, and the anti-collision plate connector is provided with an adjusting screw passing through the strip-shaped mounting hole and a nut for locking.

[0018] Furthermore, the resilient telescopic trigger mechanism comprises a shaft sleeve, the outer wall of which is fixedly connected to the fixed bracket, and a coaxially arranged spring is built into the shaft sleeve;

[0019] The contact switch is fixedly inserted in one end of the shaft sleeve, and a telescopic shaft spaced from the contact switch is slidably penetrated in the other end. The telescopic shaft can compress the spring, and the telescopic shaft is fixedly connected to the support frame connector.

[0020] Furthermore, a contact groove recessed toward the dust suction scraper body is formed on the outer surface of the front anti-collision plate.

[0021] Furthermore, the dust suction scraper body is provided with a moving wheel which is arranged on the opposite side of the front anti-collision plate.

[0022] Furthermore, a dust suction pipe connecting port is provided on the dust suction scraper body for communicating with the dust suction pipe.

[0023] Another object of the present invention is to provide a dust collection device, including a dust collection main body device, on which the dust collection main body device is provided.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] During the dust suction operation, if the substance is relatively light, it will be blocked from fine dust by the front anti-collision plate to avoid being sucked into the main body of the dust suction rake and causing pipeline blockage; when encountering an obstacle or a large piece of substance that cannot be sucked away, it will first come into contact with the front anti-collision plate. If the obstacle or substance is relatively solid, it will exert a reverse force on the front anti-collision plate, blocking the front anti-collision plate and the main body of the dust suction rake from moving forward, rather than continuing to make a forward displacement movement. Since the dust suction device is still moving forward, the main body of the dust suction rake moves downward to drive the mechanism to apply force to the rebound type telescopic trigger mechanism, causing the rebound type telescopic trigger mechanism to be compressed and trigger the contact switch, transmitting a signal to the control system of the dust suction device. At this time, the dust suction device will cut off the power and stop moving forward, thus playing a role in protecting the machine and reducing the danger caused by the collision of the dust suction device.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0035] The present invention discloses a dust suction device, including a dust suction main device. The dust suction main device can be any device with a dust suction function in the prior art. Therefore, the present invention does not limit its external structure. In this embodiment, a dust suction vehicle is taken as an example. It should be noted that this kind of dust suction vehicle has functions of driverless and remote control. The realization of these two functions lies in that a dust suction vehicle control system is provided in the dust suction vehicle. This kind of dust suction vehicle control system is a self - contained system and is the prior art, and the present invention does not make specific elaboration.

[0036] A rebound - type dust suction rake device is arranged at the front part of the vehicle body, which can well solve the problem of malfunctions caused by hard collisions when the dust suction vehicle encounters obstacles or large dust - absorbing objects during the dust suction process, and has a function of adjusting the height of the rake head. When the device is not sucking dust, the dust suction rake main body 1 can be raised. When sucking dust, the dust suction device control system controls the dust suction rake main body lowering drive mechanism 3 to lower the dust suction rake main body 1 to complete the dust suction action, thereby relatively improving the safety and operability of the dust suction main device and also extending the service life of the device.

[0037] The above - mentioned rebound - type dust suction rake device includes a dust suction rake main body 1. The dust suction rake main body 1, as the structure actually performing the dust suction action, is in the overall shape of a long cuboid and has a cavity formed inside. A dust suction pipe connection port 01 is provided on the dust suction rake main body 1. This dust suction pipe connection port 01 is used to communicate with the dust suction pipe. After a negative pressure is formed in the cavity, dust and other impurities in the cavity will enter the dust suction pipe from the dust suction pipe connection port 01 and then be collected in the dust bag in the dust suction vehicle. In addition, Figure 1 taking the orientation in [[ ]] as the standard, a dust suction rake wool strip 02 is fixedly connected to the front - facing side of the dust suction rake main body 1, and a dust suction rake rubber strip 03 is fixedly connected to the rear - facing side. When the dust suction rake main body 1 is pressed against the ground and moves forward, the dust suction rake wool strip 02 can pre - scrape the impurities sticking to the ground to facilitate being sucked away, and the dust suction rake rubber strip 03 plays a sealing role to prevent impurities from being left out.

[0038] To realize the movement of the dust suction vehicle driving the dust suction rake main body 1 and the above - mentioned function of adjusting the height of the rake head, the rebound - type dust suction rake device further includes a dust suction rake main body lowering drive mechanism 3. The dust suction rake main body lowering drive mechanism 3 is installed at the rear side of the dust suction rake main body 1. When the dust suction vehicle is not performing dust suction operation, the state of the dust suction rake main body lowering drive mechanism 3 and the dust suction rake main body 1 is as Figure 2 shown. The dust suction rake main body 1 takes its left side as the fulcrum and the rear side rises. When it works, the state of the dust suction rake main body lowering drive mechanism 3 and the dust suction rake main body 1 is as Figure 3As shown, the driving mechanism 3 for lowering the main body of the dust suction scraper moves upward, and the main body 1 of the dust suction scraper descends until its right side also contacts the ground.

[0039] As Figure 4 shown, the driving mechanism 3 for lowering the main body of the dust suction scraper specifically includes a movable support frame 4 and a fixed support 5. The fixed support 5 is generally in a U shape, with two side plates 51 on both sides and a movable support frame fixing rod 52 fixedly connected to the side plates 51 at both ends in the middle. A lifting connector port 6 is fixedly connected to the outer wall of the movable support frame fixing rod 52 for connecting a push rod motor. The push rod motor is preset on the dust suction vehicle and is controlledly connected to the control system of the dust suction vehicle. When the push rod motor makes a telescopic movement up and down, it can drive the fixed support 5 to lift. The movable support frame 4 consists of two support plates 41 symmetrically arranged with the middle cross-section of the movable support frame fixing rod 52 as the symmetry plane. The support plates 41 are in a special shape, with a smaller width at one end and a larger width at the other end. The end with the larger width is fixedly connected to the outer wall of the movable support frame fixing rod 52, and a support frame connector 7 is screwed to the end with the smaller width. To reserve an installation position for the subsequent rebound type telescopic trigger mechanism 9, the support frame connector 7 is in an L shape, and one side of the bottom of the support frame connector 7 is detachably connected to the top surface of the main body 1 of the dust suction scraper by screws.

[0040] Therefore, when the push rod motor drives the fixed support 5 to rise, it can drive the side of the main body 1 of the dust suction scraper that is originally far from the dust suction position to descend, so that the entire main body 1 of the dust suction scraper fits the ground.

[0041] From Figure 4 it can be seen that the two support frame connectors 7 are symmetrically located on both sides of the dust suction pipe connection port 01, so that the movable support frame 4 is also distributed on both sides of the dust suction pipe connection port 01, and there is a certain distance between the movable support frame fixing rod 52 and the dust suction pipe connection port 01. Therefore, a closed space is formed between the main body 1 of the dust suction scraper and the movable support frame 4 and the fixed support 5. When a soft corrugated dust suction pipe is installed on the dust suction pipe connection port 01, the aforementioned space can facilitate the bending and deformation of the dust suction pipe during the dust suction process and prevent interference with the normal operation of the dust suction pipe. Optimally, the inner side edge of the support plate 41 is in an arc shape, which can also reduce the wear on the dust suction pipe if it contacts the dust suction pipe.

[0042] Since when the dust suction vehicle is not performing dust suction operations, the main body 1 of the dust suction scraper presents a state as Figure 2 shown, and the entire dust suction scraper device has a certain weight. If it is suspended as a whole, it will affect the structural strength of the dust suction vehicle. If it moves with the left edge of the main body 1 of the dust suction scraper contacting the ground for a long time, it is easy to wear the dust suction rubber strip 03 on the main body 1 of the dust suction scraper. For this reason, as Figure 4As shown in the figure, two moving wheels 11 are rotatably mounted on the top of the dust suction rake main body 1 through a mounting seat. The number of them is not limited, and industrial universal moving casters can be used. In this embodiment, the two moving wheels 11 are respectively located at both ends of the dust suction rake main body 1, and their bottoms are in contact with the ground. During the walking of the dust suction vehicle, it cooperates with the dust suction vehicle to make the dust suction and walking flexible and convenient, and has strong bearing capacity.

[0043] In the prior art, in the utility model with the publication number of CN210493946U, universal wheels and auxiliary wheels are respectively arranged on the front and rear sides of the cross beam. When in use, the dust suction rake is placed on the cross beam, and the whole device is moved through the universal wheels and the auxiliary wheels. When the dust suction rake device in the prior art works, the universal wheels and the auxiliary wheels are arranged in the same plane as the bottom surface of the cross beam, which often causes the moving speed to be too fast and the staying time in each dust suction area to be too short, resulting in poor dust suction effect. Compared with the prior art, although the moving wheels 11 are directly arranged on the dust suction rake main body 1 in the present invention, there is a height difference between the moving wheels 11 and the bottom surface of the dust suction rake main body 1. The moving wheels 11 are only used when dust suction operation is not required. Specifically, when the dust suction rake main body lowering drive mechanism 3 raises the dust suction rake main body 1, at least one moving wheel 11 is arranged at the rear side of the dust suction rake main body 1. This kind of moving wheel 11 mainly plays the role of gravity bearing and then the role of auxiliary movement. During the dust suction process, the moving wheels 11 are tilted up to avoid driving the dust suction rake main body 1 to move too fast.

[0044] In order to protect the dust suction vehicle when encountering obstacles or large dust suction objects during the dust suction process, the retractable dust suction rake device further includes a front anti-collision plate 10. The front anti-collision plate 10 is arranged on the front side of the dust suction rake main body 1. It can be seen that the front placement plate is on a different side from the dust suction rake main body lowering drive mechanism 3 and the moving wheels 11, and is arranged in a front-back dislocation with the dust suction rake main body 1. Therefore, there is a certain interval between the front anti-collision plate 10 and the dust suction rake main body 1. When in the dust suction process, when the front anti-collision plate 10 contacts relatively light substances, such as plastic bags, foam boards, paper balls, etc., these light substances and fine dust will be blocked by the front anti-collision plate 10 to avoid being sucked into the dust suction rake main body 1 and causing the dust suction pipeline to be blocked.

[0045] Such as Figure 4As shown, in detail, one side of the front anti-collision plate 10 is integrally connected with two symmetrically arranged anti-collision plate connectors 12. In order to avoid hindering the installation of the rebound telescopic trigger mechanism 9, a fan-shaped connecting plate 71 is fixedly connected to the bottom of the support frame connector 7. The anti-collision plate connector 12 and the fan-shaped connecting plate 71 partially overlap and are jointly pierced with screws to connect with the lower side of the support frame connector 7. In addition, the fan-shaped connecting plate 71 is provided with an arc-shaped strip mounting hole 711, and the anti-collision plate connector 12 is pierced with an adjustment screw 8. The adjustment screw 8 passes through the strip mounting hole 711 at the same time, and the adjustment screw 8 is locked with a nut on the other side to realize the detachable connection between the anti-collision plate connector 12 and the support frame connector 7. The front anti-collision plate 10 of the present invention adopts an independent mounting structure, which can be disassembled and replaced separately, which is convenient for later maintenance.

[0046] By adjusting the position of the adjusting screw 8 on the strip-shaped mounting hole 711, the front and rear position and the up and down position of the entire front anti-collision plate 10 relative to the dust suction shovel body 1 can be adjusted. Since the adjusting screw 8 can be used as the rotation center, when the adjusting screw 8 is not locked, the front anti-collision plate 10 is in a hinged relationship with the dust suction shovel body 1. The inclination angle of the front anti-collision plate 10 relative to the dust suction shovel body 1 can also be adjusted, and the front anti-collision plate 10 can be flipped closer or farther away from the dust suction shovel body 1, so that the position of the front anti-collision plate 10 can be adjusted according to the size of the collision object that usually appears on the scene, and the collision prevention effect can be better achieved against the collision object. It should be noted that the end of the adjusting screw 8 is formed with a larger diameter hand-held portion, and the surface of the hand-held portion is formed with a groove that increases the contact area, which is convenient for the staff to hold and operate.

[0047] It should be noted that the outer surface of the front anti-collision plate 10 is formed with a contact groove 13 that is recessed toward the vacuum cleaner main body 1. As can be seen from the figure, the cross section of the front anti-collision plate 10 is an open C-shape. When it contacts an obstacle, such as a paper ball, it can wrap the obstacle with a larger contact area and push away lighter impurities. In addition, the outer surface of the front anti-collision plate 10 can be provided with a visually prominent coating, such as a yellow coating, which has a strong warning effect and prevents people around from bumping into it.

[0048] During the vacuuming process, in addition to lighter impurities such as plastic bags, foam boards, and paper balls, there may also be larger, heavier, and more solid obstacles. Figure 5 and Figure 6Before the collision, since the dust scraper body is in a fitted state for normal dust collection, the front anti-collision plate 10 is in a vertical state as a whole. After colliding with a relatively solid obstacle, a reverse force will be applied to the front anti-collision plate 10 to push the front anti-collision plate 10. In the process of the front anti-collision plate 10 and the dust scraper body 1 being blocked, with one side (the right side) of the dust scraper body 1 as the fulcrum, similar to the principle of a lever, the dust scraper body 1 and the front anti-collision plate 10 jointly perform a flipping motion centered on the fulcrum, and the side of the dust scraper body 1 provided with the moving wheel 11 is tilted instead of continuing to make forward displacement motion.

[0049] At this time, if the vacuum cleaner ignores the obstacle and continues to move forward and vacuum, it will inevitably cause a hard collision with the vacuum cleaner, which is dangerous. In this regard, the reboundable vacuum cleaner device also includes a rebound telescopic trigger mechanism 9, such as Figure 4 The rebound telescopic trigger mechanism 9 is jointly arranged on the dust scraper main body downward driving mechanism 3 and the dust scraper main body 1. When the dust suction vehicle continues to move forward by inertia after encountering a large obstacle, the dust scraper main body downward driving mechanism 3 and the dust scraper main body 1 cooperate to trigger the rebound telescopic trigger mechanism 9 to cut off the power supply to the dust suction vehicle.

[0050] The rebound telescopic trigger mechanism 9 corresponds to two support frame connectors 7, and two fixing plates 51 are also provided. Figure 7 As shown, the specific mechanical structure for realizing the trigger is as follows: the resilient telescopic trigger mechanism 9 includes a sleeve 91, a spring 92, a telescopic shaft 93 and a contact switch 94. A strip plate 14 with a fixing hole 15 is fixedly connected to the outer wall of the sleeve 91, and the strip plate 14 is fixedly connected to the through hole on the fixing plate 51 through the fixing hole 15 by screws, so as to realize the connection between the resilient telescopic trigger mechanism 9 and the fixing bracket 5.

[0051] Secondly, a spring 92 is coaxially arranged inside the sleeve 91, and the length of the spring 92 matches the length of the sleeve 91. A contact switch 94 is fixedly inserted inside one end of the sleeve 91, and the contact switch 94 is connected to the control system of the vacuum cleaner vehicle. A telescopic shaft 93 is slidably penetrated at the other end and is spaced apart from the contact switch 94. One end of the telescopic shaft 93 inside the sleeve 91 is sleeved inside the spring 92, and a convex ring with a diameter equal to that of the spring 92 can be integrally provided on its outer wall, and the convex ring abuts against one end of the spring 92. When the telescopic shaft 93 is forced to penetrate into the sleeve 91, the spring 92 can be compressed, and a fixing hole 15 is also provided at the other end of the telescopic shaft 93, and the fixing hole 15 is fixedly connected to the through hole on the support frame connector 7 by screws, thereby realizing the connection between the rebound telescopic trigger mechanism 9 and the vacuum cleaner body 1.

[0052] When the front anti-collision plate 10 and the main body 1 of the dust suction scraper stop moving forward, while the dust suction vehicle continues to move forward, the elastic telescopic trigger mechanism 9 is forced by the driving mechanism 3 for moving down the main body of the dust suction scraper. Specifically, during the process that the movable support frame 4 rotates downward relative to the support frame connector 7, the distance between the fixed support 5 and the support frame connector 7 is reduced, resulting in the compression of the telescopic shaft 93 under force and its penetration into the shaft sleeve 91. The end of the telescopic shaft gradually approaches the proximity switch 94. At the same time, the spring 92 is compressed to store elastic potential energy until the proximity switch 94 is triggered, and a transmission signal is sent to the control system of the dust suction vehicle. At this time, the dust suction vehicle will cut off the power supply and stop moving forward, thus playing a role in protecting the machine and reducing the danger caused by the collision of the dust suction vehicle.

[0053] After the collision object is removed, the front anti-collision plate 10 is no longer blocked, and the main body 1 of the dust suction scraper returns to fit with the ground. At the same time, under the action of the elastic force of the spring 92, the telescopic shaft 93 extends out of the shaft sleeve 91 and no longer contacts the proximity switch 94. At this time, the control system of the dust suction vehicle can restore the power supply to the dust suction vehicle, and continue to move forward for dust suction operation.

[0054] In the prior art, actually, anti-collision plates are also provided at the dust suction position of the dust suction device. For example, in the utility model with the publication number CN206729834U, an outer anti-collision plate is provided on the front side, and this kind of outer anti-collision plate can compress the buffer spring 92 under force to buffer the collision force. Compared with the prior art, the front anti-collision plate 10 of the present invention does not buffer the collision force through retraction movement. Instead, it uses the rigid collision between the front anti-collision plate 10 and the obstacle to force the main body 1 of the dust suction scraper to stop running, and then uses the driving mechanism 3 for moving down the main body of the dust suction scraper to drive the main body 1 of the dust suction scraper forward. The specific cooperation content regarding the movable support frame 4, the support frame connector 7, and the fixed support 5 has been described above and will not be repeated here. Based on the normal driving of the dust suction vehicle, without the need to additionally set a device for triggering the elastic telescopic trigger mechanism 9, the telescopic shaft 93 can penetrate into the shaft sleeve 91 by itself to trigger the proximity switch 94.

[0055] Generally speaking, based on the prior art, if a power-off trigger mechanism is provided on the dust suction device, it is most likely to trigger the power-off trigger mechanism by using the retraction movement of the outer anti-collision plate. However, since the front anti-collision plate 10 of the present invention cannot retract during a rigid collision. That is to say, in the present invention, the connection and cooperation relationship between the front anti-collision plate 10 and the main body 1 of the dust suction scraper, the connection and cooperation relationship among the movable support frame 4, the elastic telescopic trigger mechanism 9, and the support frame connector 7, and the connection and cooperation relationship between the movable support frame 4 and the support frame connector 7 are all essential improvement contents set to prevent safety accidents caused by collisions of the dust suction vehicle, which reflects the creative labor of this application.

[0056] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered by the protection scope of the present invention.
