Description

Technical Field

[0001] The utility model relates to the technical field of hot air blowers, in particular to an energy-saving air source hot air blower. Background Art

[0002] A fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. Fan is the customary abbreviation for gas compression and gas transportation machinery in China. Commonly referred to fans include ventilators, blowers, and wind turbines.

[0003] An existing patent (publication number: CN218210095U) discloses an air source hot air blower with a self-cleaning function. It installs a slide rail at the front end of the air source hot air blower. When cleaning the grid at the front end of the air source hot air blower, the electric push rod on the mounting plate is connected to the power supply in advance. The electric push rod drives the sliding frame to slide back and forth on the slide rail. At the same time, the water-absorbing sponge brush on the sliding frame can contact and scrub the grid. Water can also be poured into the small water tank from the water inlet, and the pump body in the small water tank is turned on. The pump body discharges water from the outlet pipe into the water-absorbing sponge brush, so that the water-absorbing sponge brush can easily clean the grid, and the cleaning liquid can also be put into the small water tank for cleaner cleaning.

[0004] However, the above technical solution still has certain defects. The above device uses a water-absorbing sponge brush to regularly scrub the grid. After the water-absorbing sponge brush scrubs the grid for a period of time, the dust and scale on the outer wall of the grid are squeezed into the inner wall of the grid and are not easy to be cleaned. At this time, the grid needs to be disassembled for deep cleaning to prevent energy waste during use due to grid blockage and poor use effect. The above device is relatively cumbersome to disassemble and assemble the grid, and the water-absorbing sponge brush is slidably connected to the outer wall of the grid, which further causes the inconvenience of disassembling and assembling the grid. For this reason, an energy-saving air source hot air blower is proposed. Utility Model Content

During the insertion process, the trapezoidal block is squeezed until the L-shaped plug is completely inserted into the bottom of the slot. The trapezoidal block loses the squeeze of the L-shaped plug, and the elastic force of the limit spring is used to push the trapezoidal block to move back to the back side of the L-shaped plug to complete its fixation.

[0016] 2. The utility model designs a cleaning component and a water injection component. The starting motor drives the mounting plate and the water-absorbing sponge brush to move to one side of the grid. At this time, the protrusion will move synchronously until the protrusion contacts the pressure plate and begins to apply pressure to the pressure plate. The pressure plate drives the piston rod and the piston to move to the bottom of the inner cavity of the piston cylinder. At this time, the return spring will be squeezed, and the cleaning liquid inside the piston cylinder will be squeezed through the water outlet pipe and the bellows into the mounting plate, so that the water-absorbing sponge brush can easily clean the grid. It is worth noting that the mounting plate and the water-absorbing sponge brush are initially at the front end side of the air source hot air blower body, so as not to hinder the subsequent disassembly and assembly of the grid. As the mounting plate and the water-absorbing sponge brush move to one side of the grid, the dust attached to the surface of the grid will be cleaned to prevent the grid from being clogged by dust in the air and affecting the normal use of the air source hot air blower body.

[0028] 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. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] The following describes an embodiment of the present invention based on its overall structure.

[0030] An energy-saving air source hot air blower, such as Figure 1-6As shown, it includes an air source hot air blower body 100, a mounting frame 110 is provided at the front end of the air source hot air blower body 100, a grid 120 is fixedly installed on the inner side of the mounting frame 110, the mounting frame 110 is fixedly connected to the air source hot air blower body 100 through a fixing component 200, a cleaning component 300 is provided on one side of the grid 120, and a water injection component 400 is installed on one side of the air source hot air blower body 100; the fixing component 200 includes four slots 210 opened at the four corners of the front end of the air source hot air blower body 100, and an active chamber 220 is opened at one end of the inner side of each slot 210, and a trapezoidal Block 230, the trapezoidal block 230 is fixedly connected to a connecting column 240 at one end away from the slot 210, and the other end of the connecting column 240 extends through to the outside of the air source hot air blower body 100, and the two groups of connecting columns 240 located on both sides of the air source hot air blower body 100 are respectively fixedly connected to the same pull rod 260, and the outer wall of each group of connecting columns 240 is sleeved with a limiting spring 250, one end of the limiting spring 250 is fixedly connected to the trapezoidal block 230, and the other end is fixedly connected to one side of the active chamber 220, and the four corners of the installation frame 110 close to the side of the air source hot air blower body 100 are fixedly installed with L-shaped plug blocks 270 matching the slot 210.

[0031] When the grid 120 needs to be disassembled for deep cleaning or the internal components of the air source hot air blower body 100 need to be repaired or replaced, the pull rods 260 on both sides of the air source hot air blower body 100 are pulled to drive the connecting column 240 and the trapezoidal block 230 to slide in the active chamber 220 until the trapezoidal block 230 is disengaged from the slot 210, releasing the limit of the trapezoidal block 230 on the L-shaped plug 270. At this time, the limit spring 250 is compressed, and the mounting frame 110 and the grid 120 are removed for deep cleaning or repair of the internal components of the air source hot air blower body 100. After the operation, the installation frame 110 and the grid 120 are reinstalled to the front end of the air source hot air blower body 100, and the L-shaped plug 270 is then inserted into the symmetrical slot 210. During the insertion process, the trapezoidal block 230 is squeezed until the L-shaped plug 270 is completely inserted to the bottom of the slot 210. The trapezoidal block 230 loses the squeezing of the L-shaped plug 270, and the elastic force of the limit spring 250 itself is used to push the trapezoidal block 230 to move back to the back side of the L-shaped plug 270 to complete its fixation. By setting the fixing component 200, it is greatly facilitated for the operator to disassemble and assemble the grid 120, thereby improving work efficiency.

[0032] Please refer to Figure 1 and Figure 2As shown, the cleaning component 300 includes a threaded screw 310 arranged horizontally above the air source hot air blower body 100, and a motor 320 is installed at one end of the threaded screw 310. The output end of the motor 320 is fixedly connected to one end of the threaded screw 310 through a connecting vessel, and the motor 320 is fixedly connected to one side of the air source hot air blower body 100 through a machine base. The threaded screw 310 is connected to the top of the air source hot air blower body 100 through a fixing seat, and the bottom of the air source hot air blower body 100 is fixed through a fixing seat. A sliding rod 380 is fixedly connected, a first slider 330 is threadedly connected to the outer wall of the threaded screw 310, and a second slider 370 is slidably connected to the outer wall of the sliding rod 380. One side of the first slider 330 and the second slider 370 are fixedly connected to an L-shaped connecting rod 340, and the other ends of the two groups of L-shaped connecting rods 340 are fixedly connected to the same mounting plate 350. A water-absorbing sponge brush 360 is fixedly installed on the side of the mounting plate 350 close to the grid 120, and the water-absorbing sponge brush 360 is in contact with the grid 120.

[0033] After the air source hot air blower body 100 has been operating for a period of time, the motor 320 is started by the controller, and the output end of the motor 320 drives the threaded screw 310 to rotate, thereby driving the first slider 330 to slide to one side, and with the cooperation of the two sets of L-shaped connecting rods 340 and the sliding rod 380 and the second slider 370, the mounting plate 350 is driven to move to one side synchronously. It is worth noting that the mounting plate 350 and the water-absorbing sponge brush 360 are initially at the front end side of the air source hot air blower body 100, so as not to hinder the subsequent disassembly and assembly of the grid 120. As the mounting plate 350 and the water-absorbing sponge brush 360 move to one side of the grid 120, the dust attached to the surface of the grid 120 is cleaned to prevent the grid 120 from being blocked by dust in the air, affecting the normal use of the air source hot air blower body 100.

[0034] Please refer to Figure 1 and Figure 3As shown, the water injection assembly 400 includes a mounting base 410 fixedly mounted on one side of the air source hot air blower body 100, a piston cylinder 420 is fixedly mounted on the mounting base 410, a piston 430 is mounted inside the piston cylinder 420, a piston rod 440 is fixedly connected to one side of the piston 430, a water inlet pipe 480 is fixedly connected to one side of the bottom of the piston cylinder 420, a water storage tank 490 is fixedly mounted on the other end of the water inlet pipe 480, the water storage tank 490 is fixedly connected to one side of the air source hot air blower body 100 through a fixing plate 4910, a water outlet pipe 4920 is fixedly connected to the other side of the bottom of the piston cylinder 420, and a corrugated Tube 4930, the other end of the bellows 4930 is fixedly connected to one side of the mounting plate 350, a return spring 470 is fixedly installed between the bottom of the inner cavity of the piston cylinder 420 and the piston 430, and a pressure plate 450 is fixedly installed on the end of the piston rod 440 away from the piston 430. A group of L-shaped connecting rods 340 are fixedly connected to the upper end with a protrusion 460, and the protrusion 460 and the pressure plate 450 are located on the same straight line. A one-way valve is fixedly installed inside one end of the water inlet pipe 480 and the water outlet pipe 4920, and a support frame 4940 is fixedly installed on the outer wall of one end of the water outlet pipe 4920, and one end of the support frame 4940 is fixedly connected to one side of the air source hot air blower body 100.

[0035] As the L-shaped connecting rod 340 moves, the protrusion 460 fixedly connected to the upper end of the L-shaped connecting rod 340 moves synchronously until the protrusion 460 contacts the pressure plate 450 and begins to apply pressure to the pressure plate 450. The pressure plate 450 drives the piston rod 440 and the piston 430 to move toward the bottom of the inner cavity of the piston cylinder 420. At this time, the return spring 470 will be squeezed, and the cleaning liquid inside the piston cylinder 420 will be squeezed through the outlet pipe 4920 and the bellows 4930 into the mounting plate 350. The mounting plate 350 and the water-absorbing sponge brush 360 are interconnected, so that the water-absorbing sponge brush 360 can easily clean the grid 120. When 360 moves back, the protrusion 460 on the L-shaped connecting rod 340 begins to separate from the pressure plate 450, and the elastic force of the reset spring 470 itself is used to form a thrust on the piston 430, driving the piston 430 and the piston rod 440 to reset. During the reset process, negative pressure is generated in the piston cylinder 420, and the cleaning fluid in the water tank 490 will enter the piston cylinder 420 through the water inlet pipe 480 to pre-store cleaning fluid for the next scraping and cleaning. By setting the bellows 4930, the length of the bellows 4930 can be freely expanded and contracted with the movement of the mounting plate 350, and the support frame 4940 plays a supporting role for the water outlet pipe 4920 and the bellows 4930.

[0036] During use, when the grid 120 needs to be disassembled for deep cleaning or the internal components of the air source hot air blower body 100 need to be repaired or replaced, pull the pull rods 260 on both sides of the air source hot air blower body 100 to drive the connecting column 240 and the trapezoidal block 230 to slide in the active chamber 220 until the trapezoidal block 230 is disengaged from the slot 210, releasing the limit of the trapezoidal block 230 on the L-shaped plug 270. At this time, the limit spring 250 is compressed, and the installation frame 110 and the grid 120 are removed for deep cleaning or maintenance of the internal components of the air source hot air blower body 100. After the operation is completed, the installation frame 110 and The grid 120 is reinstalled to the front end of the air source hot air blower body 100, and the L-shaped plug 270 is then inserted into the symmetrical slot 210. During the insertion process, the trapezoidal block 230 is squeezed until the L-shaped plug 270 is completely inserted into the bottom of the slot 210. The trapezoidal block 230 loses the squeezing of the L-shaped plug 270, and the elastic force of the limit spring 250 itself is used to push the trapezoidal block 230 to move back to the back side of the L-shaped plug 270 to complete its fixation. By setting the fixing component 200, the operator is greatly facilitated in disassembling and assembling the grid 120, and the work efficiency is improved. The parts not involved in the device are the same as the existing technology or can be implemented using the existing technology.

The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
