[0026] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.

[0027] The following is combined with Figure 1-Figure 8 This embodiment is described in further detail.

[0028] like Figure 1-3 As shown, a fast heat supply radiator with a built-in fan in this embodiment includes a housing 100, a cavity 201 with upper and lower ends opened is provided in the housing 100, and a heat dissipation component is provided in the cavity 201, wherein, as shown in FIG. Figure 1 and Figure 2 As shown, the housing 100 includes a front panel, a rear panel, and side panels installed on the left and right sides of the front panel and the rear panel, forming a cavity 201 with upper and lower ends opened; The heat dissipation component includes a water inlet pipe 101 and a water outlet pipe 102 extending out of the shell 100 at one end, and the water inlet pipe 101 and the water outlet pipe 102 are respectively extended through the same side plate, and a connected heat dissipation pipe 210 is evenly distributed between the water inlet pipe 101 and the water outlet pipe 102 in the cavity 201, and heat dissipation fins 211 are evenly distributed outside the heat dissipation pipe 210 along its height direction; a lower cover plate 220 is provided at the lower end opening of the cavity 201, and an air inlet 221 is distributed on the lower cover plate 220; an upper cover plate 110 is provided at the upper end opening of the cavity 201, and an air outlet 111 is distributed on the upper cover plate 110, thereby, when the heating radiator is actually used, the heat dissipation component is compatible with the existing water circulation The water circulation heating system is connected, and the hot water generated by the water circulation heating system enters through the water inlet pipe 101, flows out through the water outlet pipe 102 through the heat dissipation pipe 210, and returns to the water circulation heating system, wherein the water inlet pipe 101, the water outlet pipe 102 and the heat dissipation pipe 210 are all made of copper pipes, and the heat in the hot water passing through the heat dissipation pipe 210 is transferred to the heat dissipation fins 211, thereby heating the air in the cavity 201, wherein, through the arrangement of the air inlet 221 and the air outlet 111, the outside air can enter the cavity 201 through the air inlet 221, and after heat exchange with the heat dissipation fins 211, it is discharged from the air outlet 111, thereby enabling the heating radiator to provide heat to the outside; Among them, a partition 230 is provided in the cavity 201 and above the lower cover 220, and a fan assembly for blowing air upwards is provided on the partition 230 corresponding to the heat dissipation pipe 210, and a vibration assembly for driving the lower cover 220 to vibrate is provided on the fan assembly located in the middle; a descaling assembly for scraping scale on the inner wall of the heat dissipation pipe 210 is provided in the heat dissipation pipe 210, and the descaling assembly includes a rotating rod 310 with two ends respectively extending through the water inlet pipe 101 and the water outlet pipe 102, a scraper 701 is provided on the rotating rod 310, and a driving assembly for cooperating with the corresponding fan assembly is provided at the lower end of the rotating rod 310, and a lifting and lowering blocking plate 240 for blocking the air outlet 111 is provided in the cavity 201 and below the upper cover 110, and a clutch assembly cooperating with the upper end of the rotating rod 310 is provided on the blocking plate 240.

[0029] In this embodiment, the fan assembly is provided to promote the upward flow of air in the cavity 201. Compared with the natural convection of the existing air, it can promote the flow of air, thereby realizing that the heating radiator can quickly provide heat; It should be noted that, by setting the air inlet 221 and the air outlet 111, the dust from the outside is attached to the heat dissipation fins 211 as the air flows, thereby affecting the heat dissipation of the heat dissipation fins 211. Therefore, in this embodiment, a filter (not shown in the figure) is provided on the lower side surface of the lower cover plate 220 corresponding to the air inlet 221 to filter the air entering the cavity 201 through the air inlet 221. At the same time, in order to prevent the dust from entering the cavity 201 through the air outlet 111 and attaching to the heat dissipation fins 211 when the heating radiator is not working, the air outlet 111 is closed by lifting the blocking plate 240, thereby solving the problem of dust attaching to the heat dissipation fins 211 as the air flows. In actual use, in order to realize the lifting and lowering of the blocking plate 240, a cylinder fixing plate is relatively arranged on the side wall of the cavity 201 located at the upper part, and a cylinder 320 is arranged on the cylinder fixing plate for driving the blocking plate 240 to lift and lower. A notch 241 which is offset from the air outlet 111 is arranged on the blocking plate 240. The notch 241 is offset from the air outlet 111, so that when the cylinder 320 drives the blocking plate 240 to move up and fit the upper cover plate 110, the air outlet 111 can be blocked, and when the cylinder 320 drives the blocking plate 240 to move down, the hot air after heat exchange in the cavity 201 can be discharged from the notch 241 and the air outlet 111. It should be pointed out that the flow of hot water in the heat pipe 210 will cause scale to be generated in the heat pipe 210, thereby affecting the heat transfer of the heat pipe 210 to the heat fins 211, and affecting the heat dissipation effect of the heat supply radiator. Therefore, the descaling component in this embodiment can scrape and remove the scale on the inner wall of the heat pipe 210. In actual use, a drain valve (not shown in the figure) is provided on the extended end of the water outlet pipe 102, that is, the drain valve is opened, and the descaling component is started to scrape and remove the scale on the inner wall of the heat pipe 210, so that the scale generated by scraping can be discharged through the drain valve along with the residual water in the heat dissipation component; The rotating rod 310 and the scraper 701 are arranged so that the rotating rod 310 can rotate to drive the scraper 701 to rotate, thereby scraping the scale on the inner wall of the heat dissipation pipe 210; Among them, through the setting of the driving component, the driving component can drive the fan component to drive the rotating rod 310 to rotate, so that the descaling component works with the fan component to descaling the inner wall of the heat dissipation pipe 210; In actual use, in order to prevent the heating radiator from operating and causing the fan assembly to rotate the rotating rod 310 through the driving assembly to scrape the inner wall of the heat pipe 210, resulting in the scale being circulated into the water circulation heating system, which may easily cause damage to the water circulation heating system, in this embodiment, the clutch assembly is arranged so that in actual use, when the blocking plate 240 moves downward, the clutch assembly is driven to release the cooperation with the rotating rod 310. At this time, even if the driving assembly drives the fan assembly to rotate the rotating rod 310, it will not drive the scraper 701 to scrape the heat pipe. 210 is scraped, and when the blocking plate 240 moves up to drive the clutch assembly to cooperate with the rotating rod 310, at this time, the driving assembly drives the fan assembly to drive the rotating rod 310 to rotate, and then drives the scraper 701 to scrape the inner wall of the heat pipe 210. As a result, when the heating radiator is in operation, the driving assembly cannot drive the descaling assembly to work. When the heating radiator is not working, the driving assembly drives the fan assembly to drive the descaling assembly to work, so as to perform maintenance on the heating radiator and at the same time, prevent the scale generated by the descaling assembly from circulating into the water circulation heating system.

[0030] In this embodiment, combined with Figure 5 As shown, a mounting hole is provided on the partition 230 corresponding to the heat dissipation pipe 210 , and the fan assembly includes a mounting frame 510 arranged in the mounting hole. A rotatable shaft 521 is provided on the mounting frame 510 through a dual-axis motor 520 , and a fan 522 is provided on the shaft 521 .

[0031] Through the above structure, the present embodiment enables the mounting bracket 510 to be threadedly connected to the corresponding mounting hole, thereby realizing the installation of the fan assembly on the partition 230; The dual-axis motor 520 can drive the rotating shaft 521 to drive the fan 522 to rotate. The fan 522 is used to blow the air at the bottom of the cavity 201 upward, thereby promoting the flow of air in the cavity 201.

[0032] Combination Figure 2 , 3 As shown in Figure 6, in this embodiment, a mounting rod 610 penetrating the lower cover plate 220 is relatively provided on the bottom wall of the cavity 201, a nut 611 is threadedly connected to the through end of the mounting rod 610, and a first spring 620 for pushing the lower cover plate 220 upward is sleeved on the mounting rod 610; the vibration component includes a convex ring 250 on the lower cover plate 220, grooves 531 are evenly distributed along the circumference of the convex ring 250, an inclined surface 532 is provided on one side wall of the groove 531, and a top rod 523 slidingly abutting against the convex ring 250 is evenly distributed at the lower end of the rotating shaft 521 through a connecting plate, and the rotating shaft 521 rotates to drive the top rod 523 to slide into the groove 531 or slide out of the groove 531 along the inclined surface 532, so as to realize the vibration of the lower cover plate 220.

[0033] In this embodiment, Figure 1 and Figure 3 As shown, air inlet recesses are formed at the lower ends of the front panel and the rear panel, and external air can enter through the air inlet recesses, and enter the cavity 201 through the air inlet 221 after being filtered by the filter; The convex ring 250 is coaxially arranged with the rotating shaft 521 at the middle position at the center position of the upper side surface of the lower cover plate 220. One side wall of the groove 531 is provided with an inclined surface 532, and the other side forms a vertical surface. Therefore, in cooperation with the lifting effect of the first spring 620, the rotating shaft 521 can rotate to drive the push rod 523 to slide into the groove 531 along the vertical surface of the groove 531, and then the push rod 523 abuts against the bottom wall of the groove 531, so that the lower cover plate 220 vibrates, and the dust attached to the filter screen on it falls off to ensure the filtering effect of the filter screen. At this time, the rotating shaft 521 continues to rotate, which can drive the push rod 523 to slide out of the groove 531 along the inclined surface 532. Therefore, the rotating shaft 521 continues to rotate, which can drive the lower cover plate 220 to generate continuous vibration, so that the filtering effect of the filter screen on it is better. Combination Figure 7 and Figure 8 As shown, in this embodiment, an upper friction disk 710 is provided at the lower end of the rotating rod 310; the driving assembly includes a retaining ring 811 arranged on the rotating shaft 521, a liftable ring 820 is sleeved on the rotating shaft 521 located above the retaining ring 811, a frustum 821 is provided on the outer wall of the ring 820 along its circumference, a lower friction disk 830 that can be lifted and lowered and cooperates with the upper friction disk 710 is sleeved on the rotating shaft 521 located above the ring 820, and a driving member for driving the ring 820 to lift and lower is provided in the cavity 201.

[0034] In actual use of this embodiment, a limiting groove is provided on the outer side of the rotating shaft 521 and at the upper end thereof along its axial direction, and a limiting block extending into the limiting groove is provided in the lower friction plate 830, thereby realizing the keyway cooperation between the rotating shaft 521 and the lower friction plate 830, that is, the rotation of the rotating shaft 521 can cause the rotation of the lower friction plate 830; Among them, the distance between the lower friction disk 830 and the corresponding upper friction disk 710 is relatively small, that is, due to the obstruction of the upper friction disk 710, the lower friction disk 830 will not separate from the rotating shaft 521 when it is raised or lowered at the upper end of the rotating shaft 521. As a result, the driving member drives the lower friction disk 830 to move upward along the rotating shaft 521, so that the lower friction disk 830 can be pressed against the upper friction disk 710. There is a large friction force between the two due to the extrusion, so that the rotating shaft 521 can drive the rotating rod 310 to rotate. When the driving member drives the lower friction disk 830 to move downward along the rotating shaft 521, it is away from the upper friction disk 710, that is, the rotation of the rotating shaft 521 cannot drive the rotating rod 310 to rotate.

[0035] In this embodiment, the driving member includes mounting plates 540 that are relatively arranged, and a screw rod 541 and a guide rod 542 located on both sides of the ring 820 are provided between the mounting plates 540. A movable plate 550 is relatively arranged between the mounting plates 540. The screw rod 541 is threaded through the movable plate 550, and the guide rod 542 is arranged through the movable plate 550. The movable plate 550 is provided with an abutment rod 551 that abuts against the round table surface 821. The screw rod 541 rotates to drive the movable plates 550 to move closer to or away from each other.

[0036] When this embodiment is actually used, the mounting plate 540 is fixedly mounted on the front and rear panels by screws so that the driving member can be installed in the cavity 201; wherein, the movable plate 550 is positioned by passing through the guide rod 542, so that the rotation of the screw rod 541 can drive the movable plate 550 to move, wherein the thread arranged on the screw rod 541 and matching with the corresponding thread of the movable plate 550 are arranged in reverse symmetry, thereby, the rotation of the screw rod 541 can drive the movable plates 550 to approach each other, and then can drive the abutting rod 551 to approach each other, squeeze the round table surface 821 to make the ring 820 move up along the rotating shaft 521, lift the lower friction plate 830 to press against the upper friction plate 710, and when the screw rod 541 rotates, it can drive the movable plates 550 to move away from each other, releasing the abutment between the upper friction plate 710 and the lower friction plate 830.

[0037] In actual use of this embodiment, one end of the screw rod 541 extends through the shell 100, and a screw cap 543 is provided at the extended end of the screw rod 541. As a result, the user can use the screw cap 543 to drive the screw rod 541 to rotate outside the shell 100, which is convenient for the driving component to control whether the rotating rod 310 rotates for switching.

[0038] Combination Figure 4 and Figure 7 As shown, in this embodiment, the outer sleeve of the rotating rod 310 is provided with a sleeve 410 whose upper end extends out of the water inlet pipe 101, the scraper 701 is fixedly installed on the outside of the sleeve 410, and a mounting plate 420 is provided outside the protruding end of the sleeve 410, and the upper side surface of the mounting plate 420 is provided with a connecting rod 421 connected to the blocking plate 240; the clutch assembly includes a lower convex ring portion 430 which is provided on the upper side surface of the mounting plate 420 and sleeved on the outside of the rotating rod 310, and the lower convex ring portion 430 is evenly distributed with lower ratchet grooves, and a liftable fixed plate 440 is provided at the upper end portion of the rotating rod 310, and an upper convex ring portion 450 is provided on the fixed plate 440 corresponding to the lower convex ring portion 430, and upper ratchet grooves matching the lower ratchet grooves are evenly distributed on the upper convex ring portion 450.

[0039] When the blocking plate 240 is actually used, the connecting rod 421 can drive the mounting plate 420 and the sleeve 410 to move upward as a whole, so that the lower ratchet groove can be inserted into the corresponding upper ratchet groove. At this time, the lower convex ring portion 430 and the upper convex ring portion 450 are matched and fixed, that is, the rotation of the rotating rod 310 can drive the sleeve 410 to rotate, so as to realize the scraping of the scraper 701; when the blocking plate 240 moves downward, the mounting plate 420 and the sleeve 410 can be driven to move downward as a whole, and the cooperation between the lower convex ring portion 430 and the upper convex ring portion 450 is released. At this time, the rotation of the rotating rod 310 cannot drive the sleeve 410 to rotate, that is, the scraper 701 will not perform the scraping operation; A sealing gasket is provided between the sleeve 410 and the rotating rod 310, and a sealing gasket is also provided at the through end of the sleeve 410 and the through end of the rotating rod 310, thereby improving the sealing performance of the rotating rod 310 and the sleeve 410 when installed in the heat dissipation assembly; In this embodiment, a spring mounting ring 460 is provided at the upper end of the rotating rod 310, and a groove is provided on the outer wall of the rotating rod 310 and along its axial direction at the upper end. A block that slides into the groove is provided in the fixed disk 440, and a second spring 470 for driving the fixed disk 440 to move downward is provided on the rotating rod 310 located between the spring mounting ring 460 and the fixed disk 440.

[0040] Through the construction in this embodiment, through the matching arrangement of the card slot and the card block, it is better to achieve the keyway matching between the fixed disk 440 and the rotating rod 310, that is, the rotation of the rotating rod 310 can drive the fixed disk 440 to rotate, and at the same time, the fixed disk 440 can be lifted and moved along the rotating rod 310, wherein, through the arrangement of the second spring 470 and the spring mounting ring 460, when the blocking plate 240 moves up in actual use and drives the lower ratchet groove to be not fully engaged with the corresponding upper ratchet groove, at this time, the dual-axis motor 520 starts to drive the rotating rod 310 to rotate, which can make the fixed disk 440 rotate, and cooperate with the pushing action of the second spring 470, it is better to make the lower ratchet groove and the corresponding upper ratchet groove fully engage, so that the fixed disk 440 drives the sleeve 410 to rotate, and drives the scraper 701 to perform scraping operations.

[0041] Working principle: When the heating radiator is working, the cylinder 320 drives the blocking plate 240 to move downward to open the air outlet 111. At this time, the water circulation heating system provides hot water to the heat dissipation component, and the dual-axis motor 520 is started to drive the rotating shaft 521 to rotate, so that the fan 522 blows the air in the cavity 201 upward, so that the heating radiator can quickly provide heat. At the same time, the lower cover plate 220 is driven to vibrate to ensure the filtering effect of the upper filter screen; when the inner wall of the heat dissipation pipe 210 needs to be descaled, the cylinder 320 drives the blocking plate 240 to move upward to fit the upper cover plate 110, so that The air outlet 111 is closed, and at the same time, the water circulation heating system stops supplying water to the heat dissipation component. At this time, by screwing the screw cap 543 to drive the screw rod 541 to rotate, the movable plates 550 are driven to approach each other to move the lower friction disk 830 upward, squeezing the corresponding lower friction disk 830, and then starting the dual-axis motor 520 to drive the rotating rod 310 to drive the sleeve 410 to rotate, thereby driving the scraper 701 to scrape the inner wall of the heat dissipation tube 210 to make the scale on it fall off, and finally open the drain valve so that the scale produced by scraping can be discharged through the drain valve along with the residual water in the heat dissipation component.
