Description

Technical Field

[0001] This invention relates to the field of water cooling devices, and more particularly to a crystal water cooling device for lasers and a laser. Background Technology

[0002] A laser is a device used in machining for cutting and marking. When using a water cooling system, a water pump draws water from inside the cavity through the inlet pipe and sprays it back into the cavity through the outlet pipe, thus circulating the water inside the cavity and effectively dissipating heat from the laser.

[0003] In their daily work, the inventors discovered that the water-cooling device still has at least the following problems: When using the water-cooling device, the water inside the cavity is pumped out through the inlet pipe and then sprayed into the cavity through the outlet pipe, thereby circulating the water inside the cavity. This can effectively dissipate heat from the laser. However, in actual use, because the water is away from the cavity for a relatively short time, this affects the water's heat dissipation to some extent, and thus affects the laser's heat dissipation to some extent. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art by proposing a crystal water cooling device and a laser.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a crystal water cooling device for a laser and a laser, comprising a laser body, a connecting cylinder fixedly connected to the bottom of the laser body, a crystal body disposed at the bottom of the connecting cylinder, a water pump disposed on one side of the laser body, an inlet pipe fixedly connected to the bottom of the water pump and inserted into one side of the laser body, an outlet pipe fixedly connected to the top of the water pump and inserted into one side of the laser body, a cavity formed in the inner wall of the laser body, a connecting device disposed in the inner wall of the cavity, a stirring device disposed on one side of the connecting device, the connecting device comprising a steel frame disposed inside the cavity, steel plates uniformly fixedly connected to the surface of the steel frame, connecting holes uniformly formed on the surface of the steel frame, and a connecting cover fitted on the top of the laser body.

[0006] The effect achieved by the above components is as follows: when using the connecting device, the connecting cover is manually removed from the top of the laser body, and then the steel frame is manually slid into the cavity. In this way, when water with a certain temperature passes through the steel frame and steel plate, heat exchange can be carried out, thereby reducing the temperature of the water to a certain extent, which facilitates heat exchange.

[0007] Preferably, a first locking groove is formed on the inner wall of the top of the cavity, and a second locking groove is formed on the top of the laser body. A first rubber frame is provided on the inner wall of the first locking groove, and a second rubber frame is provided on the inner wall of the second locking groove. The second rubber frame is fixedly connected to one side of the connecting cover. The first rubber frame and the connecting cover are fixedly connected to the surface inside the cavity. A storage groove is formed on one side of the laser body. A fixing rod is slidably connected to the inner wall of the storage groove. The fixing rod is slidably inserted through one side of the connecting cover. A first damping rod is fixedly connected to one side of the inner wall of the storage groove. The end of the first damping rod away from the storage groove is fixedly connected to one end of the fixing rod. A first spring is sleeved on the surface of the first damping rod. One end of the first spring is fixedly connected to one side of the inner wall of the storage groove. The end of the first spring near the first damping rod is fixedly connected to one end of the fixing rod.

[0008] The effect achieved by the above components is as follows: the connecting cover is fitted onto the top of the laser body, thereby squeezing the first rubber frame into the inside of the first locking groove, squeezing the second rubber frame into the inside of the second locking groove, and then squeezing the fixing rod away from the laser body by the first spring, thereby causing the fixing rod to pass through one side of the connecting cover, thus restricting the connecting cover to the top of the laser body.

[0009] Preferably, a second damping rod is fixedly connected to both sides of the steel frame. A rectangular plate is fixedly connected to the end of the second damping rod away from the steel frame. A rubber plate is fixedly connected to the end of the rectangular plate away from the second damping rod. Semicircular grooves are evenly formed on the side of the rubber plate away from the rectangular plate. A second spring is sleeved on the surface of the second damping rod. One end of the second spring is fixedly connected to one side of the steel frame. The end of the second spring near the second damping rod is fixedly connected to one side of the rectangular plate.

[0010] The effect achieved by the above components is as follows: the rectangular plate is squeezed away from the steel frame by the second spring, which in turn causes the rubber plate to be squeezed into the inner wall of the cavity. Because the inner wall of the cavity is relatively smooth, the air inside the semi-circular groove is squeezed out of the semi-circular groove, which makes it easier to restrict the rubber plate to one side of the inner wall of the cavity.

[0011] Preferably, a connecting rope is fixedly connected to the side of the rectangular plate near the second damping rod. The connecting rope is slidably inserted through one side of the steel frame. The end of the connecting rope away from the rectangular plate is fixedly connected to one side of another rectangular plate. A connecting block is fixedly connected to the middle of the connecting rope. A locking rod is slidably inserted through the top of the connecting block. The bottom of the locking rod is fixedly connected to the top of the steel frame. A third spring is sleeved on the surface of the locking rod. One end of the third spring is fixedly connected to the top of the locking rod. The end of the third spring near the locking rod is fixedly connected to the top of the connecting block.

[0012] The effect achieved by the above components is that the connecting block is manually pulled away from the steel frame, thereby compressing the third spring. This makes it easier to pull the rectangular plate away from the inner wall of the cavity by the connecting rope.

[0013] Preferably, the stirring device includes a rotating rod, and the top of each steel plate is provided with a groove. The rotating rod is fixedly connected to the inner wall of the groove, and rotating plates are uniformly fixedly connected to the surface of the rotating rod.

[0014] The effect achieved by the above components is that when using the stirring device, the control plate drives the rotating rod to rotate, which makes it easier to control the water to be stirred, thereby facilitating heat exchange between the parts of the water with higher and lower temperatures.

[0015] Preferably, a fixing hole is provided on one side of the steel frame, and a connecting pipe is slidably connected to the inner wall of the fixing hole. The connecting pipe is slidably inserted through and inserted into one side of the inner wall of the laser body. Rubber blocks are uniformly fixedly connected to the surface of the connecting pipe. The rubber blocks are located on the side of the steel frame near the cavity. Water outlet holes are uniformly provided at the bottom of the connecting pipe. The water outlet holes are located at the top of the rotating plate.

[0016] The effect achieved by the above components is to allow water to pass into the interior of the connecting pipe, so that the water can come out through the outlet hole, and to make the water coming out of the outlet hole squeeze onto the rotating plate, which makes it easier to control the rotating plate to drive the rotating rod to rotate.

[0017] Preferably, a rubber sleeve is fitted on the surface of the end of the connecting pipe near the water pump, and the end of the rubber sleeve away from the connecting pipe is fixedly connected to the end of the outlet pipe near the cavity. A rubber ring is fixedly connected to one end of the connecting pipe, and one end of the rubber sleeve is fitted on the surface of the rubber ring.

[0018] The effect achieved by the above components is to fit the rubber sleeve onto the surface of the rubber ring fixed at one end of the connecting pipe, which facilitates the entry of water from the outlet pipe into the interior of the connecting pipe.

[0019] Preferably, an elastic tube is fixedly connected to the middle of the connecting pipe, and the elastic tube is located in the middle of the steel frame.

[0020] The effect achieved by the above components is that the length of the connecting tube can be effectively compressed through the elastic tube, which makes it easier to disassemble the connecting tube.

[0021] A laser, employing a crystal water cooling device for the laser, includes a laser body, a connecting cylinder fixedly connected to the bottom of the laser body, a crystal body disposed at the bottom of the connecting cylinder, and a water pump disposed on one side of the laser body.

[0022] In this invention, by setting up a connecting device, when using the connecting device, the connecting cover is manually removed from the top of the laser body, and then the steel frame is manually slid into the cavity. In this way, when water with a certain temperature passes through the steel frame and steel plate, heat exchange can be carried out, thereby reducing the temperature of the water to a certain extent, which facilitates heat exchange.

[0025] Example 1, as Figure 1-8 As shown, a crystal water cooling device for a laser and a laser are disclosed. A connecting cylinder 2 is fixedly connected to the bottom of the laser body 1, and a crystal body 3 is disposed at the bottom of the connecting cylinder 2. A water pump 4 is disposed on one side of the laser body 1, and a water inlet pipe 5 is fixedly connected to the bottom of the water pump 4, which is inserted into one side of the laser body 1. A water outlet pipe 6 is fixedly connected to the top of the water pump 4, which is inserted into one side of the laser body 1. A cavity 7 is formed in the inner wall of the laser body 1, and a connecting device 8 is disposed in the inner wall of the cavity 7. A stirring device 9 is disposed on one side of the connecting device 8. When using the water cooling device, the water inside the cavity 7 is drawn out through the water inlet pipe 5 by the water pump 4, and then sprayed into the cavity 7 through the water outlet pipe 6, thereby circulating the water inside the cavity 7, which can effectively dissipate heat from the laser.

[0026] Reference Figures 3 to 6The connecting device 8 includes a steel frame 810, which is disposed inside the cavity 7. Steel plates 812 are uniformly fixed to the surface of the steel frame 810. Connecting holes 811 are uniformly formed on the surface of the steel frame 810. A connecting cover 801 is fitted onto the top of the laser body 1. When using the connecting device 8, the connecting cover 801 is manually removed from the top of the laser body 1, and then the steel frame 810 is manually slid into the cavity 7. This allows heat exchange when water at a certain temperature passes through the steel frame 810 and steel plates 812, thereby reducing the water temperature to some extent. This facilitates heat exchange. A first locking groove 802 is formed on the inner wall of the top of the cavity 7, and a second locking groove 804 is formed on the top of the laser body 1. The inner wall of the first locking groove 802... A first rubber frame 803 is provided on the wall, and a second rubber frame 805 is provided on the inner wall of the second locking groove 804. The second rubber frame 805 is fixedly connected to one side of the connecting cover 801. The first rubber frame 803 and the connecting cover 801 are fixedly connected to the surface inside the cavity 7. A storage groove 806 is provided on one side of the laser body 1. A fixing rod 809 is slidably connected to the inner wall of the storage groove 806. The fixing rod 809 is slidably inserted through one side of the connecting cover 801. A first damping rod 807 is fixedly connected to one side of the inner wall of the storage groove 806. The end of the first damping rod 807 away from the storage groove 806 is fixedly connected to one end of the fixing rod 809. A first spring 808 is sleeved on the surface of the first damping rod 807. One end of the first spring 808 is connected to the storage groove 805. One side of the inner wall of the 6 is fixedly connected. The end of the first spring 808 near the first damping rod 807 is fixedly connected to the end of the fixing rod 809. The connecting cover 801 is sleeved on the top of the laser body 1, thereby pressing the first rubber frame 803 into the inside of the first locking groove 802 and the second rubber frame 805 into the inside of the second locking groove 804. Then, the first spring 808 presses the fixing rod 809 away from the laser body 1, thereby causing the fixing rod 809 to pass through one side of the connecting cover 801. This can restrict the connecting cover 801 to the top of the laser body 1. The steel frame 810 is fixedly connected to both sides of the second damping rod 813. The end of the second damping rod 813 away from the steel frame 810 is fixedly connected to a rectangular plate 814. A rubber plate 816 is fixedly connected to the end of 814 away from the second damping rod 813. Semicircular grooves 817 are evenly distributed on the side of the rubber plate 816 away from the rectangular plate 814. A second spring 815 is fitted onto the surface of the second damping rod 813. One end of the second spring 815 is fixedly connected to one side of the steel frame 810, and the end of the second spring 815 near the second damping rod 813 is fixedly connected to one side of the rectangular plate 814. The second spring 815 presses the rectangular plate 814 away from the steel frame 810, thereby pressing the rubber plate 816 into the inner wall of the cavity 7. Because the inner wall of the cavity 7 is relatively smooth, it also squeezes the air inside the semicircular grooves 817 out of the semicircular grooves 817, thus confining the rubber plate 816 to one side of the inner wall of the cavity 7.A connecting rope 818 is fixedly connected to the side of the rectangular plate 814 near the second damping rod 813. The connecting rope 818 is slidably inserted through one side of the steel frame 810. The end of the connecting rope 818 away from the rectangular plate 814 is fixedly connected to one side of another rectangular plate 814. A connecting block 819 is fixedly connected to the middle of the connecting rope 818. A locking rod 820 is slidably inserted through the top of the connecting block 819. The bottom of the locking rod 820 is fixedly connected to the top of the steel frame 810. A third spring 821 is sleeved on the surface of the locking rod 820. One end of the third spring 821 is fixedly connected to the top of the locking rod 820. The end of the third spring 821 near the locking rod 820 is fixedly connected to the top of the connecting block 819. Manually pulling the connecting block 819 away from the steel frame 810 compresses the third spring 821, making it easier to pull the rectangular plate 814 through the connecting rope 818, thus facilitating the movement of the rubber plate 816 away from the inner wall of the cavity 7.

[0027] Reference Figure 7 and Figure 8 The stirring device 9 includes a rotating rod 902. Grooves 901 are formed on the top of the steel plate 812. The rotating rod 902 is fixedly connected to the inner wall of the grooves 901. Rotating plates 903 are uniformly fixedly connected to the surface of the rotating rod 902. When using the stirring device 9, the rotating plates 903 are controlled to drive the rotating rod 902 to rotate, thus facilitating the stirring of water and promoting heat exchange between the hotter and colder parts of the water. A fixing hole 905 is formed on one side of the steel frame 810. A connecting pipe 906 is slidably connected to the inner wall of the fixing hole 905. The connecting pipe 906 is slidably inserted through and inserted into one side of the inner wall of the laser body 1. Rubber blocks 910 are uniformly fixedly connected to the surface of the connecting pipe 906. The rubber blocks 910 are located on the side of the steel frame 810 near the cavity 7. Water outlet holes 909 are uniformly formed at the bottom of the connecting pipe 906 and are located on the top of the rotating plate 903, allowing water to flow into the interior of the connecting pipe 906. This allows water to exit through the outlet hole 909, and the water exiting through the outlet hole 909 is squeezed onto the rotating plate 903. This facilitates control of the rotating plate 903 to drive the rotating rod 902 to rotate. A rubber sleeve 907 is fitted on the surface of the end of the connecting pipe 906 near the water pump 4. The end of the rubber sleeve 907 away from the connecting pipe 906 is fixedly connected to the end of the outlet pipe 6 near the cavity 7. A rubber ring 908 is fixedly connected to the surface of one end of the connecting pipe 906. One end of the rubber sleeve 907 is fitted onto the surface of the rubber ring 908. By fitting the rubber sleeve 907 onto the surface of the rubber ring 908 fixed on the surface of one end of the connecting pipe 906, it is easy for water to enter the interior of the connecting pipe 906 from the outlet pipe 6. An elastic tube 904 is fixedly connected in the middle of the connecting pipe 906. The elastic tube 904 is located in the middle of the steel frame 810. The elastic tube 904 can effectively compress the length of the connecting pipe 906, which facilitates the disassembly of the connecting pipe 906.

[0028] Working principle: When using the water cooling device, water is pumped out of the cavity 7 through the inlet pipe 5 by the water pump 4, and then sprayed into the cavity 7 through the outlet pipe 6, thus circulating the water inside the cavity 7. This effectively dissipates heat from the laser. When using the connecting device 8, the connecting cover 801 is manually removed from the top of the laser body 1, and then the steel frame 810 is manually slid into the cavity 7. The second spring 815 presses the rectangular plate 814 away from the steel frame 810, thereby pressing the rubber plate 816 into the cavity 7. Because the inner wall of cavity 7 is relatively smooth, the air inside the semicircular groove 817 is squeezed out of the semicircular groove 817. This makes it easier to confine the rubber plate 816 to one side of the inner wall of cavity 7. Then, the connecting cover 801 is fitted onto the top of the laser body 1, thereby pressing the first rubber frame 803 into the first locking groove 802 and the second rubber frame 805 into the second locking groove 804. Then, the first spring 808 presses the fixing rod 809 away from the laser body 1, thereby causing the fixing rod 809 to pass through one side of the connecting cover 801. On the side, this restricts the connecting cover 801 to the top of the laser body 1, allowing heat exchange when water with a certain temperature passes through the steel frame 810 and steel plate 812, thereby reducing the water temperature to some extent. This facilitates heat exchange. Manually pulling the connecting block 819 away from the steel frame 810 compresses the third spring 821, making it easier to pull the rectangular plate 814 via the connecting rope 818. This also facilitates moving the rubber plate 816 away from the inner wall of the cavity 7. When using the stirring device 9, the rubber sleeve 907 is fitted onto the connecting pipe 9. The surface of the rubber ring 908 fixed at one end of the 06 facilitates the entry of water from the outlet pipe 6 into the interior of the connecting pipe 906, allowing the water to exit through the outlet hole 909. The water exiting through the outlet hole 909 is squeezed onto the rotating plate 903, which facilitates the control of the rotating plate 903 to drive the rotating rod 902 to rotate. This facilitates the stirring of the water and the heat exchange between the higher and lower temperature parts of the water. The elastic tube 904 can effectively compress the length of the connecting pipe 906, making it easy to disassemble the connecting pipe 906.

[0029] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
