[0031] Please refer to Figures 1 to 6 , the present utility model provides a spray cooling assembly 100, including: a flow channel member 10, the flow channel member 10 is provided with a main flow channel 111 and a plurality of first branch flow channels 121, an inlet of the main flow channel 111 is used for receiving a refrigerant medium, and a plurality of the first branch flow channels 121 are all communicated with an outlet of the main flow channel 111; a nozzle member 20, the nozzle member 20 is connected to the flow channel member 10 and covers the surfaces of the main flow channel 111 and the plurality of first branch flow channels 121, a plurality of first spray openings 21 are provided on the nozzle member 20, the first spray openings 21 are in one-to-one correspondence and communication with the first branch flow channels 121, and distances from a plurality of the first spray openings 21 to the outlet of the main flow channel 111 are equal or approximately equal. After the refrigerant medium enters from the inlet of the main flow channel 111, it passes through the main flow channel 111 and the first branch flow channels 121 in sequence and is sprayed outwards from the first spray openings 21.

[0032] Specifically, the spray cooling assembly 100 is set as two parts, namely the runner part 10 and the nozzle part 20. The runner part 10 is used to receive the refrigerant and transfer the refrigerant medium to the nozzle part 20 for spraying. The materials of both the runner part 10 and the nozzle part 20 are made of the cold-resistant material peek, that is, polyetheretherketone, which has the characteristics of high temperature resistance, cold resistance, easy processing, and high mechanical strength.

[0033] The main runner 111 is used to receive the refrigerant medium and transfer the refrigerant medium to the first branch runners 121. The main runner 111 extends along the length direction of the runner part 10 so as to receive and transfer the refrigerant. A number of first branch runners 121 are provided on the runner part 10, which are used to distribute the refrigerant flowing out of the main runner 111 through the number of first branch runners 121. A first nozzle 21 is provided on the nozzle part 20 to cooperate with the first branch runner 121. The refrigerant is distributed to each first branch runner 121 and then sprayed out from the first nozzle 21. The refrigerant is sprayed on the inner surface of the electrode through a number of first nozzles 21, so that the treatment electrode is cooled.

[0034] Such as Figure 5 and Figure 6 , the distances from a number of first nozzles 21 to the outlet of the main runner 111 are equal or approximately equal. Approximately equal means that the difference range of the distances from the first nozzles 21 to the outlet of the main runner 111 is within 50%. That is, after the refrigerant flows out of the main runner 111, it can flow to a number of first branch runners 121 uniformly in time and be sprayed out uniformly from a number of first nozzles 21, realizing uniform cooling of the treatment electrode. In addition, there can be an error in the distance from the first nozzle 21 to the outlet of the main runner 111, and the error range is within 50%. The refrigerant medium is distributed to each first nozzle 21 through the main runner 111 and the first branch runners 121, and the refrigerant medium is uniformly sprayed onto the treatment electrode through the first nozzles 21.

[0035] The arrangement form of the first branch runners can be various. It can be set in a cross shape or a star shape. The specific arrangement method can be selected according to actual needs. The refrigerant medium can be a cooling gas, a coolant, a gas-liquid mixture, etc.

[0036] In one embodiment, the main runner 111 is opened along the length direction of the runner part 10, and a number of first branch runners 121 are arranged radially along the circumference of the main runner 111. A number of first branch runners 121 form a star-shaped structure, that is, the distances from a number of first nozzles 21 to the outlet of the main runner 111 are all equal. The arrangement of the main runner 111 and a number of first branch runners 121 forms an array distribution centered on the main runner 111, which is convenient for more uniform distribution of the refrigerant medium and uniform cooling of the treatment electrode.

[0037] In another embodiment, such as Figure 2 and Figure 5, the first flow channel 121 extends along the main flow channel 111 towards the corner of the flow channel member 10. Due to the edge effect, the energy will show a distribution form that is weak in the middle and strong around. Therefore, several first flow channels 121 are arranged radially along the circumferential direction of the main flow channel 111 to cool the edge of the treatment electrode. The distribution is reasonable, which is convenient for better cooling of the treatment electrode.

[0038] The technical solution of the present utility model cools the treatment electrode by setting a spray cooling assembly 100. By setting 100 as a flow channel member 10 and a nozzle member 20, the flow channel member 10 is provided with a main flow channel 111 and a first flow channel 121. The main flow channel 111 is used to receive the refrigerant medium and transfer and distribute the refrigerant medium to each first flow channel 121. A plurality of first nozzles 21 are arranged on the nozzle member 20, and the distances from the plurality of first nozzles 21 to the outlet of the main flow channel 111 are all equal. Therefore, the refrigerant medium can be evenly sprayed on the inner surface of the treatment electrode through the first nozzles 21 on the nozzle member 20, cooling the treatment electrode evenly, preventing the electrode from being damaged, and avoiding scalding the skin of the patient at the same time.

[0039] In an embodiment of the present utility model, the flow channel member 10 is further provided with a plurality of second flow channels 122, the second flow channels 122 are in one-to-one correspondence and communication with the first flow channels 121, and the second flow channels 122 extend from the middle of the first flow channels 121 towards the outside of the first flow channels 121; a plurality of second nozzles 22 are further arranged on the nozzle member 20, and the second nozzles 22 are in one-to-one correspondence and communication with the second flow channels 122.

[0040] It should be noted that the second flow channels 122 are also provided, so that 100 forms a two-stage flow splitting structure with a main flow channel 111, a first flow channel 121 and a second flow channel 122. The refrigerant medium is distributed to the corresponding nozzles through the main flow channel 111, the first flow channel 121 and the second flow channel 122, so that the spraying area of the refrigerant medium is wide. The refrigerant medium is evenly and efficiently sprayed on the inner surface of the treatment electrode through the first nozzles 21 and the second nozzles 22 to cool the electrode and protect the skin.

[0041] The refrigerant medium reaches the nozzle for spraying and cooling through two flow path routes. The first flow path route is from the main flow channel 111 to the first flow channel 121, and then sprayed out from the first nozzle 21; the second flow path route is from the main flow channel 111 to the second flow channel 122, and then sprayed out from the second nozzle 22. As Figure 6 , the first nozzles 21 and the second nozzles 22 form a plurality of nozzles with an array distribution, and are evenly spaced on the nozzle member 20, which can ensure a wide and uniform spraying area of the refrigerant, and better cool the treatment electrode.

[0042] In an embodiment of the present utility model, the cross-sectional areas of the first flow dividing channel 121 and the second flow dividing channel 122 are equal. The path distance from the outlet of the main flow channel 111 to the end of the first flow dividing channel 121 is a first distance, and the path distance from the outlet of the main flow channel 111 to the end of the second flow dividing channel 122 is a second distance. The second distance is equal to or approximately equal to the first distance.

[0043] Specifically, the first distance is the path distance of the first flow path, and the second distance is the path distance of the second flow path; the second distance and the first distance can be set to be equal or approximately equal. In one embodiment, by setting the two distances to be equal, the cross-sectional areas of the first flow dividing channel 121 and the second flow dividing channel 122 are equal, so that the refrigerant medium flowing out of the main flow channel 111 is evenly distributed to each flow dividing channel and reaches each nozzle at the same time, so as to realize that the refrigerant medium can be evenly ejected through the first nozzle 21 and the second nozzle 22 and sprayed onto the inner surface of the treatment electrode, and the treatment electrode can be evenly cooled to ensure the consistency of the cooling effect and improve the user experience effect.

[0044] Approximately equal means that the difference range between the second distance and the first distance is within 50%. For example, in another embodiment, the second flow dividing channel 122 is perpendicular to the middle of the first flow dividing channel 121. The refrigerant medium has one more turn when entering the second nozzle 22 from the second flow dividing channel 122 than when entering the first nozzle 21 from the first flow dividing channel 121. Therefore, the second distance can be set to be slightly less than the first distance. By designing different paths, the refrigerant medium forms a path difference to compensate for the isochronism. The second distance is slightly less than the first distance, and the cross-sectional areas of each flow dividing channel are set to be equal, that is, the volumes of the refrigerant medium passing through the first flow dividing channel 121 and the second flow dividing channel 122 are equal. Thus, it can be realized that the refrigerant medium reaches the first nozzle 21 and the second nozzle 22 almost at the same time, achieving isochronous arrival. Therefore, it can be realized that the refrigerant medium is ejected onto the inner surface of the electrode isochronously and in equal amounts and efficiently through the first nozzle 21 and the second nozzle 22.

[0045] In an embodiment of the present utility model, the flow channel member 10 includes a connecting pipe 11 and a flow dividing block 12. The connecting pipe 11 is connected to one end of the flow dividing block 12. The main flow channel 111 is opened on the connecting pipe 11. The first flow dividing channel 121 and the second flow dividing channel 122 are opened on the flow dividing block 12. The nozzle member 20 is connected to the flow dividing block 12 and covers the flow dividing block 12; the first flow dividing channel 121 extends along the main flow channel 111 towards the corner point of the flow dividing block 12, and the second flow dividing channel 122 is perpendicular to the middle of the first flow dividing channel 121.

[0046] Specifically, the connecting pipe 11 is used to receive and transfer the refrigerant, and the flow dividing block 12 is used to divide the refrigerant medium; the first flow dividing channel 121 extends towards the corner point of the flow dividing block 12. The charge density at the included angle of the treatment electrode is relatively large and the heat is relatively high. Therefore, through the first flow dividing channel 121, the outermost included angle of the treatment electrode can be cooled efficiently and quickly, and the distribution is reasonable. The second flow dividing channel 122 is located in the middle of two adjacent first flow dividing channels 121, and the position arrangement is reasonable, ensuring a wide and uniform spraying area.

[0047] In an embodiment of the present utility model, the flow channel member 10 and the nozzle member 20 are connected by ultrasonic welding.

[0048] Specifically, the flow channel member 10 and the nozzle member 20 are connected by ultrasonic welding to achieve a sealing effect and avoid leakage of the refrigerant medium. In addition, ultrasonic welding lines 123 are provided on the circumferences of both the first flow dividing channel 121 and the second flow dividing channel 122; as Figure 6 , the ultrasonic welding lines 123 are arranged to surround the two flow dividing channels at equal intervals. The ultrasonic welding connection is carried out through the ultrasonic welding lines 123, and the sealing effect is better. It can ensure that the cross-sectional areas of the first flow dividing channel 121 and the second flow dividing channel 122 are the same, so that the refrigerant medium can be concentrated and quickly flow to each nozzle, reducing the disadvantages such as the retention and swirling of the cooling air flow in the internal useless space, thereby achieving equal spraying and improving the utilization efficiency of the cooling air flow.

[0049] In an embodiment of the present utility model, the caliber of the first nozzle 21 gradually decreases in the direction away from the first flow dividing channel 121; and / or, the caliber of the second nozzle 22 gradually decreases in the direction away from the second flow dividing channel 122.

[0050] Specifically, the shapes of the first nozzle 21 and the second nozzle 22 can be set according to actual needs. They can be set to have a gradually decreasing caliber, or remain unchanged, or can be set to cooperate with two sections with different calibers to achieve the actual required refrigerant spraying speed. As Figure 3 , the calibers of both the first nozzle 21 and the second nozzle 22 are set to gradually decrease. By spraying the refrigerant medium through small holes, rapid spraying can be realized, and rapid cooling of the treatment electrode can be achieved.

[0051] In one embodiment, both the first nozzle 21 and the second nozzle 22 are set as tapered holes. Through the tapered surface of the tapered holes, the refrigerant medium can pass through better. The aperture is set to gradually decrease, so that the flow rate of the refrigerant medium continuously increases. The small holes at the end of the nozzle enable the refrigerant medium to be sprayed onto the surface to be cooled at a high speed.

[0052] In an embodiment of the present utility model, the first nozzle 21 includes a first receiving section (not shown in the figure) and a first spraying section (not shown in the figure). One end of the first receiving section is communicated with the first flow dividing channel 121, the other end of the first receiving section is communicated with the first spraying section, and the diameter of the first spraying section is smaller than that of the first receiving section; and / or, the second nozzle 22 includes a second receiving section (not shown in the figure) and a second spraying section (not shown in the figure). One end of the second receiving section is communicated with the second flow dividing channel 122, the other end of the second receiving section is communicated with the second spraying section, and the diameter of the second spraying section is smaller than that of the second receiving section.

[0053] It should be noted that, in another embodiment, the first nozzle 21 and the second nozzle 22 can be set to two sections with different diameters, and the diameter of the spraying section is smaller than that of the receiving section; both the spraying section and the receiving section can be set as round holes for cooperation, or can be set as one section of round hole and one section of tapered hole for cooperation. The purpose is to make the refrigerant flow from the end with a larger diameter to the end with a smaller diameter, so as to achieve rapid spraying and better cool the motor assembly.

[0054] In an embodiment of the present utility model, all the nozzles on the nozzle member 20 are located in the non-central area of the nozzle member 20.

[0055] It should be understood that the temperature of the edge area of the treatment electrode is relatively higher than that of the central area. Therefore, all the nozzles on the nozzle member 20 are arranged in the non-central area of the nozzle member 20, that is, both the first nozzle 21 and the second nozzle 22 are located outside the central area of the nozzle member 20. Other nozzles can also be added as needed, and all are arranged in the non-central area of the nozzle member 20, which can more centrally cool the edge heating area of the treatment electrode, improve the cooling effect and enhance the user experience.

[0056] In an embodiment of the present utility model, a third nozzle is further opened on the nozzle member 20. The third nozzle is located in the central area of the nozzle member 20, and the cross-sectional area of the third nozzle is smaller than the diameter of the first nozzle.

[0057] Specifically, since the temperature of the central area of the treatment electrode is relatively low, a third nozzle is arranged in the central area of the nozzle member 20, and the diameter of the third nozzle is small. The mass of the cold medium sprayed relatively is less than that of other nozzles. Cooling the central area of the treatment electrode through a small-diameter nozzle can meet the requirements, so that the refrigerant medium is sprayed on the edge heating area of the treatment electrode intensively through other nozzles. The distribution of the refrigerant medium spraying amount is reasonable, and the treatment electrode can be cooled better.

[0058] The present utility model further provides a treatment head (not shown in the figure), which includes a treatment head body (not shown in the figure), a radio frequency electrode (not shown in the figure), and the spray cooling assembly 100 as described above. The spray cooling assembly 100 is installed on the treatment head body, the radio frequency electrode is installed on the treatment head body, the first end of the radio frequency electrode is used to fit against the user's skin, the first spray port 21 of the spray cooling assembly 100 faces the second end of the radio frequency electrode, and the spray cooling assembly 100 is used to spray a refrigerant towards the second end of the radio frequency electrode.

[0059] Specifically, the spray cooling assembly 100 is installed inside the treatment head. Inside the treatment head, the refrigerant is conveyed and sprayed through the spray cooling assembly 100, and is sprayed on the second end of the radio frequency electrode, generally on the inner surface of the radio frequency electrode. The outer surface of the radio frequency electrode is used to fit against the user's skin. Spraying the refrigerant cools the radio frequency electrode, preventing damage to the radio frequency electrode and scalding the skin, and can relieve skin pain.

[0060] For the specific structure of the spray cooling assembly, refer to the above-mentioned embodiments. Since the treatment head adopts all the technical solutions of the above-mentioned embodiments, it therefore has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated here one by one.

[0061] The present utility model further provides a treatment device (not shown in the figure), which includes a main body (not shown in the figure) and the treatment head as described above.

[0062] Specifically, the radio frequency treatment device includes a main body and a treatment head. The main body is provided with a refrigerant, and the refrigerant is conveyed through a pipeline into the treatment head, and then conveyed and ejected through 100 to cool the inner surface of the radio frequency electrode, preventing damage to the radio frequency electrode and scalding the skin, and relieving skin pain.

[0063] For the specific structure of the treatment head, refer to the above-mentioned embodiments. Since the treatment device adopts all the technical solutions of the above-mentioned embodiments, it therefore has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated here one by one.

[0064] By improving the 100 of the treatment head, the refrigerant medium can be sprayed onto the inner surface of the radio frequency electrode efficiently, quickly, isochronously and in equal amounts, ensuring the consistency of the cooling effect. When applied to a radio frequency treatment device, it can provide a better experience effect.
