Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.

In the present invention, unless specified to the contrary, use of the terms of orientation such as "upper, lower, top, bottom" or the like are generally described with respect to the orientation shown in the drawings or the positional relationship of the components with respect to each other in the vertical, or gravitational direction.

The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

As shown in fig. 1, the present invention provides a handheld tubular decontamination device 2, which comprises a decontamination mechanism, wherein the decontamination mechanism comprises an air inlet pipe 21, an upper water pipe 22 and a blocking net 23 with water holes, the blocking net 23 is arranged in the pipe cavity of the upper water pipe 22 and divides the pipe cavity into an upper air outlet pipe cavity 221 and a lower dirt containing pipe cavity 222, the air outlet pipe cavity 221 is provided with a top air outlet, the dirt containing pipe cavity 222 is provided with a bottom dirt inlet, a foaming body 5 connected with the air inlet pipe 21 is arranged in the air outlet pipe cavity 221, and the foaming body 5 diffuses bubbles to attract dirt to enter from the bottom dirt inlet and is blocked by the blocking net 23 to be retained in the dirt containing pipe cavity 222.

As shown in fig. 19, the foam 5 may have a porous structure of any material or shape; in addition, the decontamination capability of the handheld pipe type decontamination apparatus 2 can be enhanced by increasing the number of the foams 5 connected to the air inlet pipe 21.

When carrying out clean scrubbing to the water capacity body such as fish bowl, fish pond or swimming pool through this handheld tubular scrubbing device 2, usable air feeder ventilates in to intake pipe 21 to make the globular foaming body 5 that takes even pore that links to each other with intake pipe 21 evenly distribute out a plurality of tiny bubbles to the aquatic in the lumen 221 of giving vent to anger, a plurality of tiny bubbles can make the rivers that make progress in the upper hose 22 at the top gas vent come-up through lumen 221 of giving vent to anger and the in-process of discharging to the surface of water. At this time, the dirt suspended in the water container or deposited at the bottom of the water container will be converged to the bottom end dirt inlet in the dirt containing pipe cavity 222 along with the water flow; then, the dirt is obstructed by the baffle net 23 arranged between the air outlet pipe cavity 221 and the dirt containing pipe cavity 222, so that the dirt cannot float upwards continuously and can only wander and accumulate in the dirt containing pipe cavity 222; then, the dirt in the dirt containing pipe cavity 222 is only needed to be received by the receiving device and taken out of the water surface, and the dirt removing work is completed, so that the operation is easy, fast and efficient. In the decontamination process, the flow characteristic of the upward water flow generated by the uniform bubbles dispersed into the water by the foaming body 5 is gentle, so that the dirt can be prevented from being excessively washed when flowing along with the water, and the dirt is ensured not to be excessively scattered, so as to pass through the blocking net 23 and flow back to the water containing body again.

Preferably, the water feed pipe 22 may be formed in an upwardly open shape. In the process that the plurality of fine bubbles in the air outlet pipe cavity 221 continuously float upwards, the cross-sectional area of the air outlet pipe cavity 221 through which the bubbles pass is gradually increased, and the density of the bubbles is correspondingly gradually reduced, so that the flow rate of the upward water flow is gradually reduced, the continuous and smooth upward water flow is ensured to be formed in the water feeding pipe 22, and the probability that the dirt is washed and broken is further reduced. In addition, for the water supply pipe 22 applied to a small water container such as a fish tank, waste plastic bottles with a conical shape can be directly used as raw materials, so that the technical effects can be realized, and the water supply pipe is economical and environment-friendly.

Specifically, the water feeding pipe 22 may preferably be vertically arranged during the decontamination process, and the axial length of the air outlet pipe cavity 221 should be greater than the axial length of the dirt containing pipe cavity 222. When the upper water pipe 22 is vertically arranged, the change range of the upward water flow direction caused by collision between the floating bubbles and the pipe wall of the upper water pipe 22 can be reduced as much as possible, and the phenomenon that turbulent flow is formed in the upper water pipe 22 and is not beneficial to the accumulation of dirt in the dirt containing pipe cavity 222 is avoided. In addition, the air outlet pipe cavity 221 must have a certain axial length to better ensure that the pipe contains sufficient air bubbles, so that the upward water flow formed when the air bubbles float upwards has sufficient flow velocity and is continuously and smoothly; furthermore, the axial length of the dirt-containing cavity 222 is too long to facilitate the dirt entering the dirt inlet at the bottom end.

Preferably, the foam body 5 may be disposed closer to the lower barrier net 23 than to the upper tip exhaust port. At this time, since the number of bubbles near the baffle net 23 is large, the negative pressure generated in the water flow in this region is large, and it is possible to provide sufficient lift force to ensure that the dirt having been sucked into the bottom dirt inlet is always accumulated in the dirt accommodating chamber 222.

Further, the distal end of the air inlet pipe 21 may penetrate from the peripheral wall of the water feed pipe 22 into the air outlet pipe chamber 221. As can be seen from the above, the foam 5 for emitting bubbles into water is connected to the end of the air inlet pipe 21, that is, the end of the air inlet pipe 21 is a bubble emitting source. At this time, if the tail end of the air inlet pipe 21 penetrates into the dirt containing pipe cavity 222 from the peripheral wall of the upper water pipe 22, the dirt collides with the foaming body 5 for many times in the process that the dirt at the bottom end floats upwards to the baffle net 23, and part of the dirt with poor adhesion is collided and broken first; and part of the un-broken dirt is blocked by the blocking net 23 and trapped in the dirt containing pipe cavity 222 and continuously washed by turbulent water flow in the area near the bubble dispersion source below the dirt, until the dirt has enough dispersion degree to flow back to the water container through the meshes of the blocking net 23, so that the pollution degree of the water quality is further increased. Therefore, in order to avoid the above situation, it is preferable to pass the distal end of the air inlet pipe 21 from the peripheral wall of the water feed pipe 22 into the air outlet pipe chamber 221, improving the reliability of the above-described sewage disposal apparatus.

Preferably, the air inlet pipe 21 may be formed as a sleeve including an inner hose 211 for ventilation and an outer hard pipe 212 for connecting the upper water pipe 22. At this time, the above-mentioned decontamination device can be conveniently operated to scan and decontaminate any region in the water container only by holding the external hard tube 212. The outer hard tube 212 and the inner hose 211 for ventilation do not interfere with each other, that is, the sleeve structure can prevent air leakage due to breakage of the air inlet pipe 21, thereby further improving the reliability of the above-described sewage disposal apparatus.

More preferably, the outer rigid tube 212 may be provided with a connection portion 213. For example, the connecting part can be a stop lever, a sucker, a hook and the like, and is fixed on the top edge of the peripheral wall of the water container when not in use, so that the water container is prevented from being placed disorderly, a user is prevented from performing other activities, and the appearance is not influenced.

Further, the external hard pipe 212 can be formed as a telescopic pipe, which can realize the quick adjustment of the size of the decontamination device to meet the decontamination requirements of water containers with different depths.

In addition, as shown in fig. 2, the handheld pipe type decontamination device 2 further comprises a dirt holding mechanism, the dirt holding mechanism comprises a handheld rod 24, and a dirt holding container 25 for holding dirt in the dirt holding pipe cavity 222 is connected to the end of the handheld rod 24. Should receive dirty mechanism and be used for mutually supporting with sewage suction mechanism and use, when the filth is accumulated in holding dirty lumen 222, can will receive dirty container 25 through controlling handheld pole 24 earlier and arrange in holding dirty lumen 222 under to simultaneously with sewage suction mechanism with receive dirty mechanism and take out the surface of water, make the filth fall in receiving dirty container 25 in order to reach the scrubbing effect.

In particular, the hand-held rod 24 may be formed as a telescopic rod to better fit the decontamination of different sizes of the above-described soil pick-up mechanisms operating in water containers of different depths.

Preferably, as shown in fig. 3, the dirt receptacle 25 may be formed in a funnel shape flaring upward and provided with a water filtering layer 251 at the bottom. At this time, the dirt holding container 25 can be aligned and matched to the bottom of the dirt holding pipe cavity 222 more easily, so that the dirt accumulated in the dirt holding pipe cavity 222 can smoothly fall into the dirt holding container 25 in the process that the dirt absorbing mechanism and the dirt holding mechanism are drawn out of the water surface. In addition, the bottom of the dirt container 25 is provided with a water filtering layer 251, which can avoid the loss of water quantity in the excessive water container when the dirt absorbing mechanism and the dirt containing mechanism are taken out of the water surface.

Further, a hard sleeve 252 is detachably sleeved on the bottom end of the dirt containing container 25, and a cotton net serving as a water filtering layer 251 is arranged in the hard sleeve 252. The water passing gap of the cotton net is thinner and denser than the mesh of the baffle net 23, and can basically and completely bear fine dirt, so that the fine dirt is prevented from flowing back to the water container again, and the dirt cleaning capability of the dirt cleaning device is improved.

Further, as shown in fig. 4, the present invention also provides a mobile decontamination apparatus 3, comprising: a body part 31 at the top end, wherein the body part 31 comprises an end cover 314, a water filtering cavity 311 with a filtering layer and a main air inlet; a plurality of hollow support legs 32, the support legs 32 extending downward from the body 31 and having bottom ends capable of being provided with moving members such as moving wheels 321 or sliders, the top ends of the hollow cavities of the support legs 32 are respectively communicated with the water filtering cavities 311, the hollow cavities of the support legs are respectively provided with air inlet branch pipes, the top ends of the air inlet branch pipes are connected with the main air inlet, and the bottom ends of the air inlet branch pipes are connected with the foaming body 5 and extend downward to the bottom of the hollow cavities of the support legs; and a power mechanism for driving the leg 32 to move.

As shown in fig. 5, the foam 5 may have a porous structure of any material or shape; further, the decontamination capability of the mobile decontamination apparatus 3 can be enhanced by increasing the number of the foams 5 connected to the bottom end of the intake branch pipe.

When cleaning and decontaminating water containing bodies such as a fish tank, a fish pond or a swimming pool through the movable type decontamination device 3, the air supply device can be utilized to ventilate the total air inlet of the body part 31, so that the spherical foaming body 5 with the uniform pores at the bottom end of the air inlet branch pipe connected with the total air inlet uniformly distributes a plurality of fine bubbles in the supporting leg hollow cavity, the fine bubbles continuously float upwards in the supporting leg hollow cavity and enter the water filtering containing cavity 311, and the supporting leg hollow cavity is in a negative pressure state, thereby forming an upward water flow. At this time, the dirt deposited on the bottom of the water container will flow into the hollow cavity of the leg along with the upward water flow and continuously float up to the water passing frame 315, the water flow flows through the wall of the water passing frame 315 and enters the water filtering cavity 311, and the water filtering cavity 311 plays a role of accumulating the dirt. Meanwhile, the power mechanism is controlled to drive the movable wheel 321 at the bottom end of the supporting leg 32 to rotate, so that the movable decontamination device 3 can perform omnibearing scanning decontamination on the range of the bottom wall of the water container.

Specifically, as shown in fig. 6, the mobile dirt removing device 3 further includes a drain pump 36, wherein the top end of the hollow cavity of the leg is communicated with the drainage cavity 311 above the filter layer 312, and the drain pump 36 is used for externally draining the fluid in the drainage cavity 311 below the filter layer 312. It can be seen that the filter layer 312 disposed in the drainage volume 311 can effectively block dirt from entering the drainage volume 311 below the filter layer 312. Meanwhile, the purified water flow can be discharged out of the main body 31 again by the drain pump 36, so that the water flow can be recycled.

As shown in fig. 7, in an embodiment of the present invention, the mobile dirt removing device 3 employs a first power mechanism 33 as the power mechanism, and the first power mechanism 33 includes a main direction control motor 331, an auxiliary direction control motor 332, a main transmission shaft 333, an auxiliary transmission shaft 334, and a first power pump 335 and a second power pump 336 disposed at both sides of the body portion 31; wherein, the first power pump 335 and the second power pump 336 are respectively hinged at two ends of the main transmission shaft 333 and are driven by the main direction control motor 331 to rotate around the central axis of the main transmission shaft 333; and an auxiliary drive shaft 334 is coaxially disposed within the main drive shaft 333, both ends of the auxiliary drive shaft 334 being connected to a first power pump 335 and a second power pump 336, respectively, through a fine adjustment drive member, the auxiliary direction control motor 332 driving the auxiliary drive shaft 334 to rotate and driving the first power pump 335 and the second power pump 336, respectively, to pivot about respective hinge centers 337 through the fine adjustment drive member.

The main direction control motor 331, the auxiliary direction control motor 332, and the first power pump 335 and the second power pump 336 are operated independently of each other, that is, there is no mutual interference between the start and stop states of the motors. By providing the first power mechanism 33, the main direction control motor 331 can drive the first power pump 335 and the second power pump 336 hinged at two ends of the main transmission shaft 333 to rotate within a range of 360 ° around the central axis of the main transmission shaft 333, the auxiliary direction control motor 332 can drive the first power pump 335 and the second power pump 336 to pivot within a range of 180 ° around the respective hinge centers 337, and the directions of the first power pump 335 and the second power pump 336 pivoting around the respective hinge centers are opposite, that is, when the first power pump 335 rotates clockwise, the second power pump 336 rotates counterclockwise; or when the first power pump 335 is rotated counterclockwise, the second power pump 336 is rotated clockwise.

In addition, in order to realize mobile decontamination in the water-containing body, the mobile decontamination apparatus 3 must continuously push water outwards by the first power pump 335 and the second power pump 336 to generate driving power. Meanwhile, the combined start or close of the motors can be controlled, so that the dirt removing device can be switched in the directions of advancing, retreating, floating, submerging, turning and the like in the water container, and the effect of omni-directional scanning dirt removal is achieved.

More specifically, as shown in FIG. 9, the fine drive members may be formed as a pair of cooperating helical gears 338. The helical gear pair 338 is a bevel gear pair. When the auxiliary direction control motor 332 drives the auxiliary transmission shaft 334 to rotate, the bevel gears at the two ends of the auxiliary transmission shaft 334 correspondingly rotate and are respectively meshed with the bevel gears fixedly connected to the two hinge connecting rods, so as to drive the first power pump 335 and the second power pump 336 to pivot around the respective hinge centers in an opposite direction or in an opposite direction. It should be noted that the fine adjustment transmission member shown in fig. 9 is only used as a preferred structure to illustrate the technical effect to be achieved by the present invention, and should not be understood as limiting other fine adjustment transmission members capable of achieving the same technical effect, and no other specific structures are listed here.

Further, both the main drive shaft 333 and the auxiliary drive shaft 334 may be formed as gear shafts. The main direction control motor 331 drives the main transmission shaft 333 to rotate through gear engagement, and the auxiliary direction control motor 332 drives the auxiliary transmission shaft 334 to rotate through gear engagement. Meanwhile, the auxiliary direction control motor 332 needs to be fixedly connected to the main transmission shaft 333, that is, in the process of rotating the main transmission shaft 333, the auxiliary direction control motor 332 and the main transmission shaft 333 synchronously rotate at the same angular speed, so that the rotation of the main transmission shaft 333 and the auxiliary transmission shaft 334 cannot interfere with each other; alternatively, as shown in fig. 8, the auxiliary direction control motor 332 only needs to be fixed on the inner wall of the main body 31, and the rotation of the main transmission shaft 333 and the auxiliary transmission shaft 334 can be ensured not to interfere with each other. At this time, the first and second power pumps 335 and 336 can be simultaneously pivoted toward and away from each other within a range of 180 ° about the respective hinge centers 337 while rotating within a range of 360 ° about the central axis of the main transmission shaft 333. It can be seen that the mobile decontamination apparatus 3 has a direction switching function with high precision and a wide range.

Preferably, the body part 31 of the mobile sewage treatment apparatus 3 may be formed in a triangular shape, and the apparatus further includes three legs 32 downwardly protruding from three corner portions of the body part 31, and the drain pump 36, the first power pump 335, and the second power pump 336 are respectively disposed at three lateral sides of the body part 31.

It should be noted that the mobile pollutant removing device 3 is bound to receive a certain water flow resistance when moving in the water container. Therefore, by providing three legs 32 extending downward at three corners of the main body 31, the stability of the device in the water container can be improved to resist the impact of water flow resistance, and the device is prevented from being turned over due to excessive force during decontamination, thereby blocking the decontamination. Meanwhile, the above-described first and second power pumps 335 and 336 may be preferably disposed at both long side surfaces of the body part 31, respectively, and the drain pump 36 may be preferably disposed at a short side surface of the body part 31, further improving the stability of the decontamination apparatus. In addition, the drain pump 36 can generate a certain pushing force to assist the dirt removing device to move forward when the filtered water is discharged outwards, so as to ensure sufficient power.

In addition, as shown in fig. 10, in another embodiment of the present invention, the mobile pollutant removing device 3 employs the second power mechanism 34 as the power mechanism, and the second power mechanism 34 includes a buoyancy thruster 341, and the buoyancy thruster 341 is configured to discharge the fluid in the water filtering cavity 311 below the filter layer 312 and push the leg 32 to move. In addition, a power pump is disposed at the rear end of the buoyancy thruster 341, and the power pump includes a driving motor, a rotating shaft and a power impeller, wherein one end of the rotating shaft is connected to the inside of the driving motor, and the other end of the rotating shaft is fixedly connected to the power impeller, and the power impeller can rotate around the central axis of the rotating shaft.

When the buoyancy thruster 341 is used as a power source of the mobile decontamination device 3, the driving motor drives the power impeller to rotate first, and the power impeller pushes water outwards to drive the decontamination device 3 to move forwards; then, in the process that the movable type decontamination device 3 scans the bottom wall dirt of the water container, the end part of the rotating shaft connected with the power impeller can be controlled to rotate by a specific angle around the central axis of the rotating shaft, so that the direction switching of the device, such as oblique floating or turning, can be realized.

Preferably, as shown in fig. 11, the body 31 of the mobile pollutant removing device 3 using the second power mechanism 34 may further include a lifting driving motor 342, the buoyancy thruster 341 further includes a hollow lifting pipe 343 having a top end extending into the water filtering cavity 311, and the filtered water in the water filtering cavity 311 below the filter layer 312 can flow to the buoyancy thruster 341 through the hollow lifting pipe 343. In addition, the elevation driving motor 342 may drive the hollow elevating tube 343 to move up and down, and a rotation shaft output end of the elevation driving motor 342 and an outer circumferential wall of the hollow elevating tube 343 may be partially formed to be gear-engaged. In this case, in order to ensure the stability of the above-mentioned sewage disposal apparatus during the movement, the center of gravity of the apparatus may be always located near the center of the entire apparatus structure as much as possible. Therefore, during decontamination, the buoyancy thruster 341 generally has to be lowered to a position near the middle of the leg 32 to more stably propel the device to move; when there is a barrier in the water container, such as a decoration member with a certain height, which may collide with the buoyancy thruster 341, the hollow elevating tube 343 may be driven to move upward by controlling the elevating driving motor 342 to avoid the tall object, thereby preventing the buoyancy thruster 341 from being damaged by collision, and ensuring that the mobile decontamination apparatus 3 can purify the water in the water container stably and efficiently.

More preferably, the above-described mobile pollutant removal device 3 may further include a controller and a sensor disposed at a peripheral wall of the body part 31, the sensor generating a trigger signal upon sensing an obstacle in front of movement, the controller being configured to control the driving of the elevating driving motor 342 according to the trigger signal of the sensor such that the buoyant thruster 341 avoids the obstacle. In other words, when the dirt removing apparatus encounters an obstacle during the moving process, the controller can automatically control the lifting driving motor 342 to drive the hollow lifting pipe 343 to move upwards to avoid the obstacle in front of the moving process, and at this time, the remote control function should be in a closed or standby state. Alternatively, the lifting driving motor 342 can be controlled by a remote controller to drive the hollow lifting pipe 343 to move upwards to avoid the obstacle in front of the movement, and at this time, the controller automatic control function is in a closed state.

In addition, when the water level line in the water filtering cavity 311 is higher than the water inlet at the top end of the hollow cavity of the support leg, the phenomenon that the sewage flows back into the water container occurs, which causes secondary pollution to the water quality in the water container. Therefore, to avoid this, the above-mentioned decontamination apparatus further comprises a controller and a liquid level float 35 disposed in the water filtration volume 311 above the filter layer 312, the controller being configured to control the drainage power of the buoyancy thruster 341 accordingly in accordance with a position signal of the liquid level float 35.

When the water level line in the water filtering cavity 311 is not higher than the water inlet at the top end of the hollow cavity in the leg, the metal block 354 and the metal contact switch 352 are not in contact with each other, that is, a certain distance is left between the metal contact switch 352 and the metal block 354. In addition, the reset metal block 355 is arranged below the metal block 354, and when the water level line in the water filtering cavity 311 is not higher than the filtering layer, the reset metal block 355 and the metal block 354 are always in contact with each other.

In the decontamination process of the mobile decontamination device 3, when the water level line in the drainage cavity 311 rises to be flush with the water inlet at the top end of the hollow cavity of the leg, the metal contact switch 352 and the metal block 354 contact with each other, and a closed circuit formed by connecting the power supply 357, the reset metal block 355, the indication signal generator 356 and the metal contact switch 352 in series in sequence is powered on. At this time, the indication signal generator 356 correspondingly sends out an indication signal, and the controller immediately controls and executes the action of increasing the drainage power of the buoyancy thruster 341 after receiving the indication signal, so as to ensure that the water level line in the water filtration cavity 311 is lower than the top water inlet of the hollow cavity of the support leg again, thereby preventing the sewage in the water filtration cavity 311 from flowing back to the water container body to cause secondary pollution.

In other words, during the moving decontamination process of the mobile decontamination apparatus 3, the cleaning mechanism 37 may be disposed below the main body 31 to clean the bottom of the water container. It should be noted that the cleaning mechanism 37 and the body 31 are detachably configured to facilitate cleaning, maintenance, or replacement. The sweeping mechanism 37 controls a sweeping motor 375 to drive a transmission gear 373 in a central vertical shaft 372 to rotate through a controller, and the transmission gear 373 further drives a disc-shaped sweeper 371 with the top meshed with the transmission gear 373 to rotate, so that dirt accumulated in sand at the bottom of the water container is swept to a suspension space of the water container. At this time, the above-mentioned decontamination device can absorb the filth into the water filtration containing cavity 311 quickly, and reduce the decontamination dead angle in the water containing body as much as possible, thereby realizing efficient decontamination.

Further, the above-described cleaning mechanism 37 may also be formed to include a plurality of cleaning unit blocks 374 in one-to-one correspondence with the respective legs 32, the cleaning mechanism 37 unit blocks being disposed inside the bottom ends of the corresponding legs 32.
