Description

Technical Field

[0001] The invention relates to the technical field of interior decoration, in particular to a wall punching device for interior decoration. Background Art

[0002] Interior decoration includes room design, decoration, furniture arrangement and various small decorations. It focuses on the decoration construction inside the building, not only during the decoration design and construction period, but also includes the long-term decoration after moving in;

[0003] In indoor decoration, electric drills are commonly used wall drilling devices, but existing electric drills generally do not have a dust reduction function. For example, an electric drill with a publication number of CN108941692A generates a lot of dust at the hole in actual use, especially when the electric drill is used to drill holes in the wall. Since the drill bit is continuously screwed into the wall, the dust generated when drilling the hole will be pushed back in front of the construction workers, which directly affects the construction workers' observation of the hole, easily leading to the hole being skewed, and if inhaled, it will affect the health of the construction workers.

[0004] At the same time, after searching, it is found that the electric drills currently on the market generally only use fans to drive natural wind to dissipate heat for the motor inside the electric drill. When the ambient temperature is high, this cooling method has a poor cooling effect on the motor and is difficult to meet the heat dissipation requirements of the motor when working in a high temperature environment.

[0058] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] Example 1: Please refer to Figures 1 to 11 The present invention provides a technical solution of a wall punching device for indoor decoration: comprising a main structure 1, one end of which is rotatably connected to a drilling structure 4 for drilling a hole in a wall;

[0060] The host structure 1 includes a housing 11, a motor 14 is installed inside the housing 11, a first handle 15 is connected to the bottom of the housing 11, a battery for powering the device is detachably connected to the bottom of the first handle 15, a switch 16 for controlling the working state of the device is installed on one side of the first handle 15, and a connecting frame 19 is fixedly connected to the side wall of the housing 11. For details, refer to Figure 1 A connection slot is provided at the end of the connection frame 19, and a protective cover is magnetically connected inside the connection slot. More specifically, the protective cover is located between the drilling structure 4 and the host structure 1, and can block dust to a certain extent to reduce the impact of dust on construction personnel;

[0061] One end of the connecting frame 19 is fixedly connected to a dust removal box 101, the inner wall of the dust removal box 101 is fixedly connected to a first partition plate 102, the inner wall of the dust removal box 101 is fixedly connected to a second partition plate 103 at a position on one side of the first partition plate 102, the end of the shell 11 is fixedly connected to a cover plate 12 by bolts, and a ventilation slot 13 is penetrated through the side wall of the cover plate 12 for ventilating the inside of the shell 11;

[0062] The side wall of the second partition 103 is fixedly connected with the first sleeve 81, and the side wall of the second partition 103 is fixedly connected with the second sleeve 82 at a position outside the first sleeve 81, and the outer surface of the second sleeve 82 is rotatably connected with the adjustment sleeve 83, and the outer surface of the first sleeve 81 is rotatably connected with the extrusion block 86 through a thread, and the extrusion block 86 is located outside the drilling structure 4, and the inner wall of the first sleeve 81 is rotatably connected with the swivel 84, and the side wall of the swivel 84 is rotatably connected with the clamping plate 85;

[0063] Specifically, refer to Figure 3 The inner wall of the extrusion block 86 is fixedly connected with a clamping rod, and the inner wall of the adjustment cylinder 83 is provided with a docking groove that matches the size of the clamping rod. Under the limiting effect of the clamping rod and the docking groove, when the adjustment cylinder 83 rotates, the extrusion block 86 will be driven to rotate at the same time, and when the extrusion block 86 rotates, it will move axially on the surface of the first sleeve 81 through the thread, and by Figure 3 As shown, the inner cavity of the extrusion block 86 is provided with a conical groove. When the extrusion block 86 moves toward the clamping plate 85, the end of the clamping plate 85 away from the rotating ring 84 is squeezed. At this time, the clamping plate 85 performs a circular motion with the end connected to the rotating ring 84 as the center, and the other end of the clamping plate 85 can squeeze the surface of the drilling structure 4 to ensure that the drilling structure 4 can be firmly connected to the end of the host structure 1.

[0064] And by Figure 3 It can be seen that the end of the splint 85 away from the swivel 84 is rotatably connected to a slider, and the inner wall of the extrusion block 86 is provided with a slide groove that matches the size of the slider. Under the limiting action of the slider and the slide groove, when the extrusion block 86 moves in the direction away from the swivel 84, the slider slides in the slide groove and drives the end of the splint 85 that clamps the drilling structure 4 to move upward, thereby facilitating the removal of the drilling structure 4.

[0065] The output end of the motor 14 is connected to a transmission structure 2 for driving the drilling structure 4 to rotate;

[0066] The bottom end of the main structure 1 is located on one side of the first handle 15 and is connected to a water storage structure 3 for storing water;

[0067] A water pumping structure 5 for supplying water to the drilling structure 4 is installed inside the dust removal box 101 .

[0068] The water storage structure 3 includes a second handle 31 fixedly connected to the bottom end of the shell 11, the bottom end of the second handle 31 is fixedly connected to a limiting ring 32, the top of the limiting ring 32 is fixedly connected to a plurality of support rods 33 distributed in an annular shape, the tops of the plurality of support rods 33 are commonly connected to a support plate 34, the bottom end of the support plate 34 is fixedly connected to a sealing spring 36, the bottom end of the sealing spring 36 is located above the limiting ring 32 and is fixedly connected to a sealing plate 37, the top of the supporting plate 34 is fixedly connected to a limiting column 38, the top of the limiting column 38 is fixedly connected to a fixing ring 302, the outer surface of the limiting column 38 is located between the supporting plate 34 and the fixing ring 302 and is sleeved with a sealing block 39, the outer surface of the limiting column 38 is located below the sealing block 39 and is also sleeved with an electromagnet 301, when the switch 16 is turned on, the electromagnet 301 is in an energized state, at which time the electromagnet 301 can push the sealing block 39 upward by magnetic force, so as to facilitate the pumping structure 5 to pump water;

[0069] Specifically, when the water in the second handle 31 is pumped into the dust removal box 101 under the action of the pumping structure 5, the sealing block 39 will compress the sealing spring 36 under the action of air pressure, and then the air flow can enter the second handle 31 through the gaps between the plurality of support rods 33, and the air flow is discharged from the second handle 31 by the air pumping structure 5. Figure 2 As shown, an arc groove for air flow is formed at the top of the support plate 34. Therefore, when the air flow enters the second handle 31, it can enter the top of the sealing plate 37 through the arc groove, and push the water upward through the sealing block 39, further avoiding the water gap between the dust removal box 101 and the second handle 31, so as to ensure that the pumping structure 5 can effectively pump water, and when water is added, the air pressure in the second handle 31 returns to normal. At this time, the sealing spring 36 will push the sealing plate 37 back to close the limit ring 32, further avoiding water leakage in the second handle 31.

[0070] The side wall of the second handle 31 is fixedly connected with a protective shell 304, and the top of the protective shell 304 is fixedly connected to the bottom of the dust removal box 101, and the inside of the protective shell 304 is connected with a water pipe 305 for supplying water to the inside of the dust removal box 101;

[0071] The top of the dust removal box 101 is fixedly connected with a water inlet pipe 104 , and the top of the water inlet pipe 104 is detachably connected with a sealing cover 105 for sealing through threads. Specifically, after the sealing cover 105 is removed, the inside of the second handle 31 can be replenished with water through the water inlet pipe 104 .

[0072] The transmission structure 2 includes a rotating rod 21 connected to the motor 14 through a coupling, and the end of the rotating rod 21 away from the motor 14 is fixedly connected to a rotating disk 22, and the side wall of the rotating disk 22 is fixedly connected to a fixing rod 23, and the pumping structure 5 is connected to the outer surface of the fixing rod 23. For details, refer to Figure 3, the rotating rod 21 is not concentric with the fixed rod 23;

[0073] The pumping structure 5 includes a connecting ring 51 fixedly connected to the outer wall of the fixing rod 23, and a plurality of pull blocks 52 distributed in an annular shape are fixedly connected to the outer wall of the connecting ring 51. A support rod 53 is rotatably connected to the inside of the pull block 52, and one end of the support rod 53 is rotatably connected to a pull rod 54, and one end of the pull rod 54 is connected to a piston block 55;

The plurality of second water pumping pipes 57 are interconnected by pipelines, and one end of one of the second water pumping pipes 57 away from the first water pumping pipe 56 is also connected to a first one-way solenoid valve 58.

[0075] The side wall of the second partition 103 is fixedly connected with a regulating pipe 501, and the outer walls of the plurality of first water pumping pipes 56 are fixedly connected with water supply pipes 59, and one end of the plurality of water supply pipes 59 is connected with the regulating pipe 501;

[0076] Specifically, the outer wall of the piston block 55 fits with the inner wall of the first water pumping pipe 56. When the piston block 55 moves upward, the water in the dust removal box 101 will be sucked into the first water pumping pipe 56 by the second water pumping pipe 57. Then, when the piston block 55 moves downward, under the action of the unidirectional flow limiting of the first one-way solenoid valve 58, the water in the first water pumping pipe 56 will be pushed into the water supply pipe 59.

[0077] A transmission rod 25 is rotatably connected to the center of the side wall of the second partition plate 103, one end of the transmission rod 25 is fixedly connected to a connecting pipe 27, and the outer wall of the connecting pipe 27 is fixedly connected to a plurality of water intake plates 502 distributed in an annular shape, and a plurality of water intake holes 503 for taking water are opened on the side wall of the water intake plate 502;

[0078] One end of the fixed rod 23 is fixedly connected to a gear 24, the inner wall of the transmission rod 25 is connected to a gear ring 26, and the gear 24 meshes with the gear ring 26;

[0079] One end of the connecting pipe 27 away from the transmission rod 25 is connected to a connecting seat 28, and a slot 29 is provided on one side of the connecting seat 28. A water injection pipe 202 for injecting water into the drilling structure 4 is fixedly connected to the center of the inner cavity of the slot 29, and the water injection pipe 202 is communicated with the connecting pipe 27.

[0080] Specifically, the gear 24 drives the transmission rod 25 to rotate through the ring gear 26, and the transmission rod 25 drives the water intake plate 502 to rotate through the connecting pipe 27. At this time, the water in the dust removal box 101 will enter the connecting pipe 27 through the water intake hole 503 under the drive of the water intake plate 502, and supply water to the inside of the drilling structure 4 through the water injection pipe 202.

[0081] The interior of the dust removal box 101 is also connected to a cooling structure 6 at a position outside the water pumping structure 5;

[0083] Specifically, since the pumping structure 5 works under the action of the transmission structure 2, as long as the device is in working condition, the pumping structure 5 will continuously perform suction operations. In order to avoid damage to the device due to excessive water pressure, when the water pressure in the device reaches a certain level, the first one-way solenoid valve 58 is closed and the second one-way solenoid valve 63 is opened. At this time, the pumping structure 5 no longer pumps water, but instead draws air through the exhaust pipe 62 and discharges the extracted gas out of the dust removal box 101.

[0085] The inner wall of the slot 29 is fixedly connected with a plurality of limiting rods 201 distributed in an annular shape, and the outer wall of the connector 41 is provided with a plurality of connecting grooves 42 that are in accordance with the size of the limiting rods 201. Specifically, when the connector 41 is connected to the slot 29, the limiting rods 201 are located in the connecting grooves 42 to limit the connector 41.

[0090] A reset button 70 is installed on the side of the retaining ring 72 adjacent to the adjusting plate 73, a first extrusion rod 75 is connected to the side of the adjusting plate 73 adjacent to the retaining ring 72, a second extrusion rod 77 is connected to the side of the adjusting plate 73 adjacent to the baffle 74, a reset spring 79 is sleeved on the outer surface of the second extrusion rod 77 at a position between the baffle 74 and the adjusting plate 73, specifically, when the water pressure is greater than the pressure applied by the reset spring 79 on the adjusting plate 73, the pumping structure 5 starts to pump air, and a pressure sensing unit 76 is installed on the side of the baffle 74 adjacent to the adjusting plate 73;

[0091] A panel 17 is installed on the outer wall of the shell 11 at a position on one side of the connecting frame 19, and a control button 18 is installed on the outer wall of the panel 17. The control button 18 can be used to adjust the working mode of the device according to whether there is water or no water in the second handle 31.

[0092] The top of the sealing cylinder 71 is fixedly connected to the position above the gas outlet cylinder 702, and a pressure relief valve 707 is installed at one end of the arc-shaped air pipe 601 located in the inner cavity of the sealing cylinder 71. Specifically, when the air pressure in the sealing cylinder 71 is too high, the gas will be discharged through the pressure relief valve 707. The other end of the arc-shaped air pipe 601 is connected to the exhaust pipe 602 for exhaust.

[0093] The outer surface of the limiting column 38 is located between the sealing block 39 and the fixing ring 302, and is sleeved with a coil 603, and one end of the coil 603 is connected to the exhaust pipe 602, and the other end of the coil 603 is connected to the bellows 604, and a dehumidification box 606 is fixedly installed on the side of the second handle 31 opposite to the protective shell 304, and the inner cavity of the dehumidification box 606 has a plurality of activated carbons for dehumidifying the airflow, and the other end of the bellows 604 is connected to the bottom of the dehumidification box 606, and the top of the dehumidification box 606 is located in the inner cavity of the shell 11 and is fixedly connected to an outlet pipe 607, and the outer surface of the rotating rod 21 is located on one side of the outlet pipe 607 and is sleeved with a fan blade 608.

[0094] Specifically, the excess gas discharged from the sealing tube 71 is discharged into the exhaust pipe 602 through the arc-shaped air pipe 601, and enters the coil 603 through the exhaust pipe 602. Since the coil 603 is located in the second handle 31, the gas in the coil 603 will be cooled by the water in the second handle 31, and then the gas enters the dehumidification box 606 through the bellows 604. After the gas is dried, it is discharged into the shell 11 through the outlet pipe 607. Driven by the rotating rod 21, the fan blades 608 will rotate in the shell 11 to speed up the flow rate of the air flow inside the shell 11, thereby dissipating the heat of the motor 14. At this time, the cold air discharged from the outlet pipe 607 will flow toward the motor 14 driven by the fan blades 608, and further dissipate the heat of the motor 14.

[0095] The working principle of the present invention is:

[0096] When in use, water is added through the water inlet pipe 104. When the water is full, the port of the water inlet pipe 104 is closed through the sealing cover 105. Then, when in use, the switch 16 controls the current supply to the motor 14. After pressing the switch 16, the motor 14 starts and drives the turntable 22 to rotate through the rotating rod 21. At this time, the turntable 22 drives the gear 24 to rotate through the fixing rod 23, and the gear 24 drives the transmission rod 25 to rotate through the gear ring 26. Then the transmission rod 25 drives the connecting seat 28 to rotate through the connecting pipe 27. At this time, the drilling structure 4 connected to the slot 29 will rotate under the drive of the limit rod 201. At this time, the wall surface can be opened by the drilling structure 4;

[0097] Depend on Figure 2As shown, since the fixed rod 23 is not concentric with the rotating rod 21, when the rotating rod 21 rotates, the fixed rod 23 performs a circular motion with the rotating rod 21 as the center. At the same time, the connecting ring 51 fixedly connected to the outer wall of the fixed rod 23 drives the pull block 52 to move. At this time, the pull block 52 drives the pull rod 54 to move through the support rod 53, and then the pull rod 54 pushes and pulls the piston block 55 in the first water pumping pipe 56, so that water is pumped into the first water pumping pipe 56 through the second water pumping pipe 57, and the first water pumping pipe 56 is closed. The water in the water supply pipe 59 is pushed into the water supply pipe 59. At this time, the water in the water supply pipe 59 will enter the sealing cylinder 71 through the regulating pipe 501. Then the transmission rod 25 drives the water intake plate 502 to rotate through the connecting pipe 27. At this time, the water in the sealing cylinder 71 will enter the water injection pipe 202 through the water intake hole 503 under the drive of the water intake plate 502. At this time, the water flow enters the water diversion groove 43 through the water injection pipe 202 and is discharged through the drainage groove 44, thereby moistening the holes opened in the wall to prevent dust from spreading.

[0098] Under the action of the compression spring 402, the ball 404 is in contact with the end of the drain groove 44. Therefore, when the ball 404 is not subjected to external pressure, the water outlet of the drain groove 44 is in a closed state by the ball 404 to prevent water leakage. At the same time, when drilling a hole, the drill bit 40 needs to be in close contact with the wall. Fig.11 It can be seen that part of the position of the card ball 404 protrudes from the water outlet end of the drainage groove 44, and the water outlet end of the drainage groove 44 is slightly larger than the card ball 404. Therefore, when the hole is opened, the wall will squeeze the card ball 404, so that the card ball 404 will retract into the drainage groove 44. At this time, the water in the drainage groove 44 will seep out through the gap between the card ball 404 and the drainage groove 44, and then moisten the hole to achieve the purpose of dust reduction.

[0099] When the amount of water pumped into the pumping structure 5 is greater than the amount of water discharged from the drainage groove 44, the water will gather inside the sealing tube 71 and on the side of the adjustment plate 73 close to the baffle ring 72. When the sealing tube 71 is full of water, the water will push the adjustment plate 73 under the action of water pressure. At this time, the adjustment plate 73 approaches the baffle plate 74 until the second squeezing rod 77 squeezes the pressure sensing unit 76. At this time, when the pressure sensing unit 76 senses that the pressure exceeds the set value, the first unidirectional electromagnetic The valve 58, the water control valve 701 and the air control valve 703 are closed, and the second one-way solenoid valve 63 and the sealing valve 705 are opened. At this time, the gas enters the air extraction pipe 62 through the air supply pipe 64, and enters the annular air pipe 61 through the air extraction pipe 62. Under the operation of the drilling structure 4, the air in the annular air pipe 61 is sucked into the control pipe 501 through the exhaust head 66. At this time, the residual water in the control pipe 501 will be pushed into the water outlet cylinder 704 by the air, and discharged out of the device through the sealing valve 705.

[0100] When the water is drained, the sealing valve 705 is closed and the air control valve 703 is opened. At this time, the gas in the regulating tube 501 enters the interior of the sealing cylinder 71 and is located on the side of the baffle 74 away from the regulating plate 73. The gas will push the regulating plate 73 back when the pumping structure 5 continuously replenishes air until the first extrusion rod 75 contacts the reset button 70. At this time, the air control valve 703, the second one-way solenoid valve 63 and the sealing valve 705 are closed, and the first one-way solenoid valve 58 and the water control valve 701 are opened, so that the device returns to the pumping state.

[0101] When the air pressure in the sealing tube 71 is too high and the first extrusion rod 75 does not come into contact with the reset button 70, the gas will enter the arc-shaped air pipe 601 through the pressure relief valve 707 and be discharged into the housing 11 through the air outlet pipe 607 to further dissipate the heat of the motor 14;

[0102] Depend on Figure 1 It can be seen that there are two control buttons 18, which correspond to the water state and water-free state of the device respectively. When the device is in the water-free state, press the corresponding control button 18, and the second one-way solenoid valve 63 and the water control valve 701 are opened, and the other valves are closed. At this time, the pumping structure 5 only performs exhaust operation, and the exhausted wind can be discharged through the drain groove 44 to blow away the dust, so as to avoid the dust from clogging the drain groove 44 when the hole is opened, which is more flexible to use.

[0103] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
