Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a water pump assembly and a therapeutic device. Background Technology

[0002] With the rapid development of the medical aesthetics industry, medical aesthetic equipment is also constantly being updated and upgraded. Medical aesthetic equipment is equipped with an energy source that treats the area by emitting light waves, radio frequency microwaves, or ultrasound. During treatment, the energy source generates a significant amount of heat, therefore a water pump needs to be installed inside the medical device to cool the heat source area using liquid cooling.

[0003] However, water pumps emit vibration noise when they are working. This not only causes resonance in other internal components of the equipment, affecting the overall working efficiency and lifespan of the equipment, but also makes consumers feel uncomfortable, anxious, or even irritable, which in turn leads to resistance to the treatment process and seriously affects the user's treatment experience and satisfaction. Utility Model Content

[0004] The main purpose of this invention is to propose a water pump assembly and a treatment device, which aims to solve the problem that the noise generated by the water pump in existing medical aesthetic equipment affects the overall working efficiency and lifespan of the device, as well as the user's treatment experience.

[0005] To achieve the above objectives, the present invention provides a water pump assembly, which includes:

[0006] Soundproof enclosure;

[0007] A water pump, wherein the water pump is disposed within the soundproof enclosure; and

[0008] Sound-absorbing cotton, which is attached to the inner wall of the soundproof cover;

[0009] A reflective part is provided on the side of the sound-absorbing cotton facing the water pump and is used to reflect the noise emitted by the water pump.

[0010] In one embodiment of the present invention, the reflective part includes a reflective groove, which is formed on the surface of the sound-absorbing cotton facing the water pump.

[0011] In one embodiment of the present invention, the sidewall of the reflective groove includes multiple reflective surfaces, which are arranged circumferentially along the reflective groove, and each reflective surface is set at an obtuse angle to the surface of the sound-absorbing cotton.

[0012] In one embodiment of this utility model, the reflective part includes a reflective block, which protrudes from the surface of the sound-absorbing cotton facing the water pump.

[0013] In one embodiment of this utility model, the sound-absorbing cotton faces the mounting groove on the surface of the water pump, and the reflective block includes a first end and a second end connected to ground, the first end being embedded in the mounting groove, and the second end protruding from the surface of the sound-absorbing cotton.

[0014] In one embodiment of the present invention, the first end includes a connected end face and a plurality of peripheral side faces, the plurality of peripheral side faces being set at an obtuse angle to the end face, the first end being in contact with the groove wall of the mounting groove, and the first end and the second end being mirror images of each other with respect to their connecting surfaces.

[0015] In one embodiment of this utility model, the sound-absorbing cotton has multiple mounting grooves on its surface facing the water pump, and the multiple mounting grooves are arranged in an array. Multiple reflective blocks are provided, and each reflective block is embedded in one of the mounting grooves.

[0016] In one embodiment of the present invention, the water pump assembly further includes a buffer pad, the buffer pad being disposed on the bottom wall of the soundproof cover, and the water pump being mounted on the surface of the buffer pad;

[0017] And / or, the water pump assembly further includes an elastic element disposed between the bottom of the water pump and the soundproof cover.

[0018] In one embodiment of this utility model, the soundproof cover includes a plurality of soundproof panels, which are arranged together to form the soundproof cover, and a sealing strip is provided between two adjacent soundproof panels.

[0019] This utility model also proposes a therapeutic device, which includes a housing, a main unit, and a water pump assembly as described above. The water pump assembly and the main unit are both disposed inside the housing, and the water pump assembly performs liquid cooling on the main unit.

[0020] The water pump assembly proposed in this utility model includes a water pump, a soundproof cover, sound-absorbing cotton, and a reflector. The water pump is placed inside the soundproof cover, and the sound-absorbing cotton, which is plate-shaped, is attached to the inner wall of the cover to absorb the vibration noise emitted by the water pump. Simultaneously, a reflector is provided on the side of the sound-absorbing cotton facing the water pump to reflect the vibration noise generated by the pump. Since the water pump vibrates continuously during operation, some of the sound waves reflected by the reflector can cancel out the sound waves of subsequent vibration noise. This significantly reduces the noise level propagated from the water pump assembly to the outside environment, thereby improving the overall working efficiency and lifespan of the therapeutic device, and enhancing the user's treatment experience.

[0034] This utility model proposes a water pump assembly.

[0035] Combination Figure 1 , Figure 3 as well as Figure 4 As shown, in one embodiment of the present invention, the water pump assembly includes a water pump 10, a soundproof cover 20, sound-absorbing cotton 30, and a reflector; the water pump 10 is disposed inside the soundproof cover 20; the sound-absorbing cotton 30 is attached to the inner wall of the soundproof cover 20, and the reflector is disposed on the side of the sound-absorbing cotton 30 facing the water pump 10, and is used to reflect the noise emitted by the water pump 10.

[0036] In this embodiment, the soundproof cover 20 can be formed by multiple soundproof panels 21 through detachable connections (e.g., snap-fit, plug-in) or non-detachable connections (e.g., welding, bonding) to create a sealed soundproof cover 20. The water pump 10 is located in the center or near the center of the soundproof cover 20. Specifically, the water pump 10 can be supported and installed inside the soundproof cover 20 by an elastic support structure, or it can be directly installed at the bottom of the soundproof cover 20, or a buffer pad 40 can be set at the bottom of the soundproof cover 20 and the water pump 10 can be installed on the buffer pad 40. The sound-absorbing cotton 30 covers the inner surface of the soundproof cover 20, and its thickness is uniform and greater than the common sound wave wavelength. The side of the sound-absorbing cotton 30 facing the water pump 10 has a specially structured reflective part. This reflective part is composed of a recessed reflective area set on the surface of the sound-absorbing cotton 30, or it is composed of a raised reflective block 32, or it includes both a recessed reflective area and a raised reflective block 32.

[0037] The vibration noise generated by the water pump 10 is partially reflected by the reflector and automatically cancels out the sound waves generated by the continuous vibration of the subsequent water pump along the original propagation path, thus reducing noise. Alternatively, the noise is reflected to the surface of the sound-absorbing cotton 30 and absorbed by it. The remaining noise directly strikes the surface of the sound-absorbing cotton 30 and is absorbed by it. The porous structure of the sound-absorbing cotton 30 performs multiple diffuse reflections of the incident sound waves. The continuous friction between air molecules and the rough pore walls converts sound energy into heat energy, thereby continuously absorbing sound wave energy and ultimately achieving noise reduction. Finally, the weak sound waves transmitted through the sound-absorbing cotton 30 are blocked by the sound insulation plate 21. Therefore, this application, through multiple sound absorption and sound insulation treatments using the reflector, sound-absorbing cotton 30, and sound insulation plate 21, significantly reduces the noise transmitted from the water pump assembly to the outside world, thereby improving the overall working efficiency and lifespan of the therapeutic device and enhancing the user's treatment experience.

[0038] Combination Figure 4 and Figure 6 As shown, in one embodiment of the present invention, the reflective part includes a reflective groove 31, which is formed on the surface of the sound-absorbing cotton 30 facing the water pump 10.

[0039] In this embodiment, the inner surface of the reflector 31 adopts a composite surface design, that is, the inner surface of the reflector 31 includes multiple inclined surfaces, parabolic surfaces, arc surfaces, or combinations of reflective surfaces of different shapes. This composite surface design can achieve specific reflection of sound waves of different frequencies, so that the sound waves are reflected along a preset path. The reflected sound waves meet the incident sound waves and undergo destructive interference, thereby reducing noise; or the sound waves are reflected by one wall of the reflector 31 and then incident on the other wall of the reflector 31 or into another reflector 31. Then, the sound waves are reflected by the other wall of the reflector 31 or into another reflector 31 and meet the incident sound waves and undergo destructive interference, thereby effectively reducing noise from the sound waves.

[0040] The inner surface of the reflector groove 31 is specially treated to form a micro-rough structure. This structure can disrupt the regular reflection of sound waves and promote the conversion of sound energy into heat energy. The edges of the reflector groove 31 are designed with smooth transitions to avoid sharp joints interfering with the reflection of sound waves.

[0041] Combination Figure 6 As shown, in one embodiment of the present invention, the sidewall of the reflective groove 31 includes a plurality of reflective surfaces 311, which are set at an obtuse angle to the surface of the sound-absorbing cotton 30.

[0042] In this embodiment, the sidewall of the reflective groove 31 has a polyhedral structure, which can decompose the incident sound wave into multiple sub-beams in multiple propagation directions. This makes it easier for each sub-beam to automatically cancel out the sound wave in the original propagation path, or to automatically cancel out the sound wave after being reflected by other sidewalls of the reflective groove 31, or to be reflected and incident on the sound-absorbing cotton 30 and absorbed by the sound-absorbing cotton 30, thereby reducing noise.

[0043] The depth of the reflective groove 31 is positively correlated with the number of reflective surfaces 311. A deeper reflective groove 31 has more reflective surfaces 311, forming a more complex sound wave reflection path. The opening shape of the reflective groove 31 adopts a polygonal design, which is coordinated with the arrangement of the internal reflective surfaces 311.

[0044] In this polyhedral reflective structure, each reflective surface 311 is set at an obtuse angle (e.g., 120 degrees, 140 degrees, etc.) to the surface of the sound-absorbing cotton 30. After the sound wave is reflected by the reflective surface 311 of the reflective groove 31, some of the sound waves undergo destructive interference, while some are reflected onto another reflective surface 311. Therefore, the included angle between adjacent reflective surfaces 311 is set according to the angle of sound wave interference, for example... Figure 6 As shown, six reflective surfaces 311 are set in the reflective groove 31. Each reflective surface 311 has the same shape and area, and the included angle between adjacent reflective surfaces 311 is 60 degrees, so that the vibration sound wave can form destructive interference in the reflective groove 31, thereby effectively reducing the energy of the vibration sound wave.

[0045] Combination Figure 4 and Figure 5 As shown, in one embodiment of the present invention, the reflective part includes a reflective block 32, which protrudes from the surface of the sound-absorbing cotton 30 facing the water pump 10.

[0046] In this embodiment, the reflective sound-absorbing cotton 30 includes a raised reflective block 32 structure. The reflective block 32 can be made of glass wool, quartz, etc., and has good sound wave reflection capability. The surface of the reflective block 32 also includes multiple reflective surfaces 311. These reflective surfaces 311 can be flat, arc-shaped, or parabolic, etc., so that the reflective block 32 can effectively reflect sound waves incident from different directions and guide the direction of sound wave propagation. After being reflected by the reflective block 32, the sound waves can form destructive interference with the incident sound waves, thereby reducing noise; or after being reflected by the reflective block 32, the sound waves are incident on the surface of the sound-absorbing cotton 30 and the noise is absorbed by the sound-absorbing cotton 30.

[0047] The reflector block 32 can protrude from the surface of the sound-absorbing cotton 30, or a mounting groove 33 can be opened on the surface of the sound-absorbing cotton 30, and one end of the reflector block 32 can be embedded in the mounting groove 33.

[0048] Combination Figure 5As shown, in one embodiment of the present invention, the reflective part further includes a mounting groove 33 formed on the surface of the sound-absorbing cotton 30 facing the water pump 10, and the reflective block 32 includes a first end 321 and a second end 322 connected to the ground. The first end 321 is embedded in the mounting groove 33, and the second end 322 protrudes from the surface of the sound-absorbing cotton 30.

[0049] In this embodiment, the first end 321 of the reflector block 32 is fitted inside the mounting groove 33 to ensure structural stability. Simultaneously, the first end 321 fits tightly against the sidewall of the mounting groove 33 to ensure acoustic sealing. The second end 322 extends outward from the surface of the sound-absorbing cotton 30, its outer contour forming a smooth transition with the first end 321. The second end 322 is used to reflect sound waves. Because the first end 321 is located within the mounting groove 33, the reflector block 32 can maintain good stability during long-term use.

[0050] Combination Figure 4 and Figure 5 As shown, in one embodiment of the present invention, the first end 321 includes a connected end face and multiple peripheral side faces, all of which are set at an obtuse angle with the end face. The first end 321 is in contact with the groove wall of the mounting groove 33, and the first end 321 and the second end 322 are mirror images of each other with respect to their connecting surfaces.

[0051] In this embodiment, the peripheral surface of the first end 321 can have 3, 4, 5, 6, etc., respectively surrounding the circumference of the reflective block 32 and connecting to the end face. The angle between the peripheral surface and the end face can be 120 degrees, 140 degrees, etc., and the first end 321 and the second end 322 are mirror images of each other with the connecting surface as the plane of symmetry. The shape of the reflective block is as follows: Figure 5 As shown, the end face and multiple peripheral surfaces of the second end 322 can all serve as reflective surfaces and reflect sound waves. After being reflected by the reflective block 32, the sound waves meet the incident sound waves and undergo destructive interference, thereby reducing noise; or they are reflected to the surface of another reflective block 32, and after being reflected again by another reflective block 32, they meet the incident sound waves and undergo destructive interference, thereby reducing noise; or they are reflected to the surface of the sound-absorbing cotton 30 and absorbed by the sound-absorbing surface.

[0052] The outer contour of the first end 321 is adapted to the shape of the inner wall of the mounting groove 33. The multiple reflective surfaces 311 of the first end 321 are tightly fitted to the groove wall of the mounting groove 33 to reduce sound wave leakage from the joint and improve the stability of the reflector block 32. The connection between the first end 321 and the second end 322 is smoothly transitioned to reduce the interference of sharp connection points on the sound wave reflection path.

[0053] Combination Figure 4As shown, in one embodiment of this utility model, the sound-absorbing cotton 30 has multiple mounting grooves 33 on its surface facing the water pump 10. The multiple mounting grooves 33 are arranged in an array. Multiple reflective blocks 32 are provided, and each reflective block 32 is embedded in a mounting groove 33.

[0054] In this embodiment, the mounting grooves 33 are arranged in a matrix with uniform intervals on the surface of the sound-absorbing cotton 30. This arrangement allows the reflective blocks 32 disposed within the mounting grooves 33 to achieve the same noise reduction effect on sound waves propagating from the water pump 10 from different directions. The specific structures of the mounting grooves 33 and the reflective blocks 32 can be referred to the description in the above embodiment, and will not be further elaborated here.

[0055] In practical applications, a reflective groove 31 and a mounting groove 33 can be formed on the surface of the sound-absorbing cotton 30, and a reflective block 32 can be placed in the mounting groove 33. Therefore, the reflective part includes both the reflective groove 31 and the reflective block 32. The sound wave reflected by the reflective block 32 can be reflected along the original path and cancel out the interference with the incident sound wave to reduce the energy of the sound wave; it can also be reflected into the reflective groove 31, and then cancel out the interference after being reflected a second time by the reflective groove 31; it can also be reflected onto the surface of the sound-absorbing cotton 30 and diffusely reflected by the porous structure of the sound-absorbing cotton 30 to absorb the sound wave energy. Therefore, through this structural design, the vibration noise emitted by the water pump 10 can be absorbed by the energy through multiple reflections by the reflective block 32, the reflective groove 31, and the sound-absorbing cotton 30, thereby effectively reducing the noise of the water pump 10 from propagating to the outside world and improving the user experience.

[0056] Combination Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the water pump assembly further includes a buffer pad 40, which is disposed on the bottom wall of the soundproof cover 20, and the water pump 10 is mounted on the surface of the buffer pad 40.

[0057] And / or, the water pump assembly also includes an elastic element 50, which is disposed between the bottom of the water pump 10 and the soundproof cover 20.

[0058] In this embodiment, the buffer pad 40 can be made of a single-layer elastomer or a multi-layer composite elastomer. The buffer pad 40 includes, but is not limited to, at least one of a silicone layer, a rubber layer, and a polyurethane layer. The buffer pad 40 is connected to the bottom wall of the soundproof cover 20 by an embedded snap-fit ​​or adhesive fixation method. Its surface is provided with anti-slip texture, forming a surface contact support with the base of the water pump 10, which provides a buffering and vibration-damping effect for the water pump 10, further reducing the vibration noise generated by the water pump 10.

[0059] When the pump assembly includes a buffer pad 40, or not, the pump assembly may also include an elastic element 50, which may be a spring, sheet metal, or other elastic structure. Figure 2As shown, multiple springs are provided and are spaced apart between the bottom of the water pump 10 and the bottom wall of the soundproof cover 20 or the buffer pad 40. The multiple springs can further reduce the noise generated by the vibration of the water pump 10, thereby reducing the noise transmitted from the water pump assembly to the outside world and improving the user experience.

[0060] Combination Figure 3 As shown, in one embodiment of the present invention, the soundproof cover 20 includes a plurality of soundproof panels 21, which are arranged to form the soundproof cover 20, and a sealing strip is provided between two adjacent soundproof panels 21.

[0061] In this embodiment, multiple sound insulation panels 21 are fixed together by bolts or snap-fits, and an elastic sealing strip is provided at the joint between two adjacent sound insulation panels 21. The strip has memory recovery characteristics and can maintain the sealing effect for a long time, while reducing the leakage of sound waves from the gap between the two sound insulation panels 21, thereby improving the sound insulation effect of the soundproof cover 20 on sound waves.

[0062] This utility model also proposes a therapeutic device, which includes a housing, a main unit, and a water pump assembly. The specific structure of the water pump assembly is as described in the above embodiments. Since this therapeutic device adopts all the technical solutions of all the above embodiments of the water pump assembly, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0063] Both the water pump assembly and the main unit are housed within the casing, with the water pump assembly providing liquid cooling for the main unit. The therapeutic device can be a mid-infrared fiber laser therapy device, phototherapy device, radiofrequency therapy device, or ultrasound therapy device. By incorporating a water pump assembly within these devices, the water pump 10 cools the heat source of the device while simultaneously reducing vibration noise propagating outwards during operation, thereby improving the user's treatment experience.

[0064] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
