[0036] The technical solution of the utility model will be further described below in conjunction with embodiments and drawings.

[0037] Please also read Figures 1 to 3 The embodiment of the utility model provides a smoke extraction device 100, which includes a housing 10, an exhaust structure 20, a sound insulation structure and a shock absorbing element, wherein the housing 10 includes a base 11 and a shell 12, the shell 12 is covered on the base 11 to form a storage space 13 between the two, a fan 30 is arranged in the storage space 13, the shell 12 has a first inner wall surface 121 facing the base 11, the fan 30 has a first end 30a and a second end 30b, the first end 30a is connected to the first inner wall surface 121, the second end 30b is connected to the base 11, an air inlet 121a is arranged on the first inner wall surface 121, the first end 30a corresponds to the air inlet 121a, and the fan 30 is used to provide power for sucking smoke. One end of the exhaust structure 20 is connected to the air inlet 121a, and the exhaust structure 20 is configured to suck smoke toward the treatment site when the fan 30 is running. The sound insulation structure is located in the accommodating space 13 , is disposed around the outer circumference of the fan 30 , and is spaced apart from the housing 12 along the circumference of the fan 30 . The shock absorbing element is disposed at the bottom of the base 11 .

[0038] The utility model discloses a smoke extraction device 100 for a plasma therapy device 1 and a plasma therapy device 1. For smoke with a protein smell generated during treatment, the exhaust structure 20 can be directed toward the treatment site, and the smoke can be sucked away in time by the operation of the fan 30, which can reduce the thermal damage of the smoke to the skin, reduce the spread of irritating odors, and enhance the user experience.

[0039] In addition, by surrounding the sound insulation structure around the outer periphery of the fan 30, the lateral propagation of noise can be reduced at the source, and when the smoke extraction device 100 is set inside the treatment host 200, the longitudinal vibration of the fan 30 can be reduced by using the shock-absorbing element between the base 11 and the treatment host 200. This can reduce the noise during the operation of the fan 30 from the two aspects of reducing vibration and isolating noise, further enhancing the user experience.

[0040] In a possible implementation, a mounting hole 11a may be provided on the base 11, and the box 10 is fixed in the treatment host 200 of the plasma therapy device 1 by passing a bolt through the mounting hole 11a. At this time, the shock absorbing elements may be respectively provided at positions corresponding to the mounting holes 11a. Of course, in other embodiments, the shock absorbing elements may also be provided at the entire bottom of the base 11, avoiding the position where the air is discharged, and may also play a role in reducing vibration.

[0041] It is understandable that the above-mentioned shock-absorbing element can not only reduce the vibration of the fan 30 in the longitudinal direction, but also prevent the fan 30 from vibrating and causing the box body 10 to shift in position when it is working.

[0042] Optionally, the shock absorbing element may be a silicone pad, a rubber pad, etc.

[0043] In some embodiments, see Figure 4 The first inner wall surface 121 is provided with a first stopper 1211 surrounding the outer circumference of the air inlet 121a. The first stopper 1211 extends from the first inner wall surface 121 toward the base 11. The first stopper 1211 encloses and forms an installation space 131. The installation space 131 is connected to the accommodating space 13 and the air inlet 121a. The first end 30a is installed in the installation space 131. The first stopper 1211 is configured to limit the position of the fan 30 along its own circumference. The fan 30 is installed in the installation space 131 enclosed by the first stopper 1211, and the first stopper 1211 is used to limit the position of the fan 30, so as to prevent the fan 30 from shaking seriously along its own circumference during operation, which is conducive to maintaining the stability of the fan 30, thereby facilitating the overall reliability of the smoke extraction device 100. In addition, the accommodating space 13 in the box body 10 can be fully utilized, so that the structural layout in the box body 10 is more reasonable.

[0044] It should be noted that the first end 30a of the fan 30 should be understood in a broad sense, that is, the first end 30a of the fan 30 does not only refer to the end of the fan 30, but also includes a part extending from the end of the first end 30a of the fan 30 to the second end 30b.

[0045] Optionally, the blower 30 may include a motor and a fan, wherein the fan is disposed at the end of the motor and is located near the air inlet 121a, and the motor is used to drive the fan blades to rotate to absorb smoke.

[0046] In a possible implementation, in order to further reduce noise, the motor can be a brushless motor, which is more stable and produces less noise during operation. In addition, the fan blades can be streamlined to reduce air resistance and turbulence during smoke absorption, further reducing noise.

[0047] Optionally, the first inner wall surface 121 may be provided with a second stopper 1212 surrounding the outer periphery of the first stopper 1211, and the second stopper 1212 extends from the first inner wall surface 121 toward the base 11, and the second stopper 1212 and the first stopper 1211 are spaced apart to form a first gap 1213 therebetween, and the sound insulation structure is at least partially located in the first gap 1213 to surround the outer periphery of the fan 30. The second stopper 1212 and the first stopper 1211 are spaced apart to form the first gap 1213, and the sound insulation structure is disposed in the first gap 1213. Thus, on the one hand, the existing structure of the first stopper 1211 can be effectively utilized to realize the reasonable utilization of the internal space of the box body 10; on the other hand, the sound insulation structure is disposed between the first stopper 1211 and the second stopper 1212, so that the sound insulation structure can be effectively fixed and the stability of the sound insulation structure can be improved.

[0048] In one example, the sound insulation structure may be a sound insulation material used to isolate the propagation of the sound generated when the fan 30 is running, such as a sound insulation board, a sound insulation felt, a polyurethane foam plastic, etc. The specific structure is not limited in the embodiment of the utility model.

[0049] In another example, the sound insulation structure can be a sound-absorbing material for absorbing the sound generated when the fan 30 is running, such as porous materials such as glass wool and metal sound-absorbing panels, which can effectively absorb the sound generated by the fan 30. The specific structure is not limited in the embodiment of the utility model.

[0050] Furthermore, along the height direction of the housing 12, the lengths of the first stopper 1211 and the second stopper 1212 extending toward the base 11 are both greater than half of the length of the fan 30, and the two are equal in length. It can be understood that if the fan 30 is roughly regarded as a cylinder, the fan 30 is equally divided into an upper half and a lower half, and the first stopper 1211 is to extend to the lower half of the fan 30, so that a larger part of the fan 30 itself is located in the installation space 131 enclosed by the first stopper 1211, which can strengthen the limiting effect of the first stopper 1211 on the fan 30, and is more conducive to improving the stability of the fan 30.

[0051] In addition, by making the first stop portion 1211 and the second stop portion 1212 of equal length, the sound insulation structure can be effectively fixed, which is more conducive to the consistency of the processing technology between the two, making the structural design more reasonable.

[0052] In some possible implementations, see Figure 2 and Figure 5 The base 11 has a second inner wall surface 111 opposite to the first inner wall surface 121, and an air outlet 111a is provided on the second inner wall surface 111, and the second end 30b is provided corresponding to the air outlet 111a. The second inner wall surface 111 is provided with a third stopper 1111 and a fourth stopper 1112 surrounding the outer periphery of the air outlet 111a, and the third stopper 1111 and the fourth stopper 1112 are arranged at intervals to form a second gap 1113 therebetween, and along the height direction of the housing 12, the sound insulation structure extends from the first gap 1213 to the second gap 1113. The design of the third stopper 1111 and the fourth stopper 1112 being arranged at intervals on the base 11 to form the second gap 1113, and the sound insulation structure is extended from the first gap 1213 to the second gap 1113, so that the sound insulation structure extends from the top to the bottom to the base 11, surrounds the fan 30 in all directions, and is more conducive to improving the sound insulation effect. On this basis, the third stop portion 1111 and the fourth stop portion 1112 can further fix the sound insulation structure, effectively improving the stability of the sound insulation structure extending to the base 11.

[0053] Optionally, the first stopper 1211 and the second stopper 1212 may be structures such as baffles and bars protruding from the first inner wall surface 121, which can satisfy the position limiting function of the sound insulation structure. Correspondingly, the third stopper 1111 and the fourth stopper 1112 may be structures such as bars and convex strips protruding from the second inner wall surface 111, which can satisfy the position limiting function of the sound insulation structure when it extends to the second inner wall surface 111. The specific structure is not specifically limited in the embodiments of the present utility model.

[0054] Optionally, a recessed portion 112 is further provided at the bottom of the base 11, and the recessed portion 112 is recessed toward the first inner wall surface 121 to form a protrusion 113 in the accommodating space 13. A plurality of through holes 112a are provided on the side wall and the top of the recessed portion 112, so that the air outlet 111a is connected to the accommodating space 13. The third stopper 1111 is arranged around the outer periphery of the recessed portion 112, and the second end 30b is connected to the protrusion 113. In this way, the protrusion 113 is formed inside the accommodating space 13, and the second end 30b of the fan 30 is connected to the protrusion 113. On the one hand, the area of ​​the air outlet 111a is increased, which is conducive to reducing the exhaust resistance; on the other hand, the second end 30b of the fan 30 can be fixed by the protrusion 113 to achieve effective connection of the fan 30.

[0055] Optionally, the recessed portion 112 may be a groove provided at the bottom of the base 11 , and the shape of the recessed portion 112 may be square, circular, or the like.

[0056] It can be understood that the above-mentioned recessed portion 112 forms an air outlet 111a, and the air outlet 111a is connected to the accommodating space 13 through a plurality of through holes 112a provided on the side wall and the top of the recessed portion 112, so that the extracted smoke can be discharged.

[0057] Optionally, the shape of the through hole 112a provided on the side wall and the top of the recessed portion 112 can be circular, square, etc., as long as the air inlet 121a can be connected to the accommodating space 13, and the embodiment of the utility model is not specifically limited.

[0058] In some embodiments, the bottom of the base 11 is further provided with a convex ring portion 114, which is arranged around the outer periphery of the air outlet 111a and protrudes in a direction away from the second inner wall surface 111, and the convex ring portion 114 is configured to be embedded in the treatment host 200 of the plasma therapy device 1. In this way, the box body 10 is embedded in the treatment host 200 of the plasma therapy device 1 through the convex ring portion 114, so that the air outlet 111a is more coherently connected to the outside, making the overall structural layout more reasonable.

[0059] Optionally, the convex ring portion 114 is a baffle plate, convex strip or other structure convexly provided on the bottom of the base 11 , and the baffle plate, convex strip or other structure encloses and forms the convex ring structure.

[0060] It can be understood that when the box body 10 is set in the treatment host 200, the base 11 is connected to the bottom surface of the treatment host 200. In order to discharge the smoke, the bottom surface of the treatment host 200 is also provided with an opening. In order to ensure the continuity of the connection between the air outlet 111a and the opening, a convex ring portion 114 is provided on the base 11. The convex ring portion 114 is embedded in the opening of the bottom surface, so that the smoke is discharged continuously through the air outlet 111a.

[0061] Optionally, a connection portion 122 may be protruded from the top of the housing 12. The connection portion 122 is arranged around the outer periphery of the air inlet 121a, and the interior of the connection portion 122 is hollow to communicate with the air inlet 121a. A threaded portion 122a is provided inside the connection portion 122 to be screwed to the air exhaust structure 20. The design of providing the connection portion 122 at the top of the housing 12 allows the air exhaust structure 20 to be inserted into the connection portion 122 and screwed to the box body 10 through the threaded portion 122a. On the basis of realizing the effective connection between the box body 10 and the air exhaust structure 20, the internal space of the box body 10 is not occupied, so that the structural design of the box body 10 is more reasonable.

[0062] Optionally, the connection portion 122 may be a connection column or a convex ring provided on the top of the housing 12 and having a through hole, and the inner wall of the through hole is provided with a threaded portion 122a.

[0063] In some embodiments, the first inner wall surface 121 is provided with a step portion 1214, the step portion 1214 is connected to the air inlet 121a and is arranged around the outer periphery of the air inlet 121a, and the first end 30a is connected to the step portion 1214. It can be understood that the step portion 1214 is located in the installation space 131, and the end of the first end 30a of the fan 30 is connected to the step portion 1214. On the one hand, the step portion 1214 can be used to limit the first end 30a of the fan 30 along its own circumference; on the other hand, the step portion 1214 can be used to set a buffer pad to avoid direct contact between the fan 30 and the housing 12, and the buffer pad of the step portion 1214 can be used to reduce the wear between the two, thereby extending the service life of the smoke extraction device 100.

[0064] The utility model discloses a plasma therapeutic device 1, see Figure 6 , including a treatment host 200 and the smoking device 100 as described in the first aspect, and the box body 10 is arranged in the treatment host 200.

[0065] Among them, the plasma therapy device 1 in this embodiment can have the same or similar beneficial effects as the smoke extraction device 100 in the above embodiment. For details, please refer to the description in the above embodiment, and the embodiment of the utility model will not be repeated here.

[0066] As can be seen from the foregoing, the exhaust structure 20 is connected to the air inlet 121a and is configured to draw smoke toward the treatment site when the fan 30 is running. Therefore, the exhaust structure 20 can be designed as a pipe. In one example, the exhaust structure 20 can be an air inlet pipe, one end of which is connected to the air inlet 121a, and the other end of which draws smoke toward the treatment site when the fan 30 is running.

[0067] In another example, the exhaust structure 20 may include a handle assembly 21 and a connecting tube 22. Specifically, the handle assembly 21 is hollow in design, one end of the connecting tube 22 is connected to the handle assembly 21, and the other end of the connecting tube 22 is connected to the air inlet 121a. During treatment, the doctor can hold the handle assembly 21 toward the treatment site to inhale the smoke.

[0068] Furthermore, the connecting tube 22 may include a hard tube 221 located inside the plasma therapy device 1 and an external soft tube 222. In order to further reduce noise, the air flow channel of the hard tube 221 located inside the plasma therapy device 1 is designed to be smoother, that is, the larger rounded corner design of the bent part of the hard tube 221 makes the transition of the bent part smoother, so that the resistance during airflow is smaller, which is beneficial to improving the efficiency of the fan 30 and also beneficial to reducing noise.

[0069] Further, see Figure 7 The handle assembly 21 may also include a shell 211 and an upper cover 212. One end of the shell 211 is connected to the connecting pipe 22, and the other end of the shell 211 is connected to the upper cover 212. The projection area of ​​the upper cover 212 in the radial direction of the shell 211 gradually increases, and the upper cover 212 is used to absorb smoke toward the treatment site. In this way, the handle assembly 21 can be directed to a larger range of the treatment site, thereby achieving a better effect of absorbing smoke.

[0070] It is understandable that the housing 211 and the upper cover 212 are both hollow and connected to the connecting pipe 22. Optionally, the projection shape of the upper cover 212 in the radial direction of the housing 211 can be square, circular, etc., as long as the projection area of ​​the upper cover 212 in the radial direction of the housing 211 gradually increases, and the specific shape is not specifically limited in the embodiment of the utility model.

[0071] The above is a detailed introduction to the smoke extraction device for plasma therapy device and plasma therapy device disclosed in the embodiment of the utility model. Specific examples are used in this article to illustrate the principle and implementation mode of the utility model. The description of the above embodiments is only used to help understand the smoke extraction device for plasma therapy device and plasma therapy device of the utility model and their core ideas; at the same time, for general technical personnel in this field, according to the idea of ​​the utility model, there will be changes in the specific implementation mode and application scope. In summary, the content of this specification should not be understood as a limitation on the utility model.
