Description

Technical Field

[0001] This utility model belongs to the field of massage tool technology, specifically relating to a low-noise fascia gun. Background Technology

[0002] Currently, massage products such as fascia guns are widely used in people's lives. Fascia guns mainly massage the body through vibration, relaxing and soothing muscles. Existing fascia guns primarily use an eccentric vibration component to drive a piston rod and massage balls on the piston rod in reciprocating motion to achieve massage. However, in existing technologies, the piston rod and the guide sleeve inside the fascia gun are in direct surface contact, meaning the contact area is large. When the eccentric vibration component drives the piston rod to reciprocate along the guide sleeve, the large contact area between the guide sleeve and the piston rod results in significant frictional resistance, leading to considerable noise and a poor user experience. Utility Model Content

[0003] This invention provides a low-noise fascia gun, which aims to solve the problem of excessive noise during use caused by the large contact area between the guide sleeve and the piston rod in existing fascia guns.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A low-noise fascia gun, comprising:

[0006] The machine body includes a vibration assembly and a piston rod inside, and a massage head outside the machine body. One end of the piston rod is connected to the output end of the vibration assembly, and the other end of the piston rod extends out of the machine body and is connected to the massage head. A guide sleeve is provided at the end of the machine body near the massage head, and a guide hole is provided inside the guide sleeve. The piston rod passes through the guide hole.

[0007] A noise reduction device is sleeved on the piston rod and located between the inner wall of the guide hole and the outer wall of the piston rod; the noise reduction device includes a plurality of noise reduction beads, which are connected in series to form a ring-shaped noise reduction device through an elastic connector, and the noise reduction device makes point contact with the outer wall of the piston rod on the inner side in the circumferential direction, and makes point contact with the inner wall of the guide hole on the outer side in the circumferential direction.

[0008] A further solution: Several noise-reducing beads are arranged at equal intervals around the circumference of the noise reducer.

[0009] Based on the above technical solution: the equidistant setting helps to maintain stability and balance when the piston rod moves back and forth in the guide hole.

[0010] A further option: the elastic connector includes several segments disposed between each pair of adjacent noise-reducing beads.

[0011] A further solution: several of the noise-reducing beads and all the elastic connectors are integrally molded.

[0012] Based on the above technical solution: the one-piece molding design facilitates processing and helps maintain stability and balance.

[0013] A further solution: the noise-reducing beads have a through hole in the middle, and the elastic connector is an elastic band that passes through all the through holes of the noise-reducing beads in sequence.

[0014] A further solution: the noise-reducing beads are spherical.

[0015] Based on the above technical solution: the spherical noise reduction beads make it easy for each noise reduction bead to form point contact with the piston rod and guide hole when connected in series to form a noise reduction device, resulting in a small contact area and lower noise.

[0016] A further embodiment: the guide sleeve is provided with a front wall located in front of the guide hole and a rear wall located behind the guide hole, and the noise reduction device is located between the front wall and the rear wall.

[0017] Based on the above technical solution: the noise reducer and the inner wall of the piston rod and guide hole are engaged through rolling contact to reduce friction and lower operating noise.

[0018] A further solution: the noise reducer is made of silicone.

[0019] Based on the above technical solution: silicone has a certain degree of elasticity, which can play a role in elastic shock absorption when the piston rod reciprocates along the guide hole, thereby further reducing working noise.

[0020] A further embodiment: The machine body is provided with a fixing groove, and the guide sleeve is disposed in the fixing groove.

[0021] The beneficial effects of this utility model are as follows:

[0022] This invention incorporates a noise reducer between the inner wall of the guide sleeve and the piston rod. The noise reducer consists of several noise-reducing beads connected in series by elastic connectors. The noise reducer makes point contact with both the inner wall of the guide hole and the outer wall of the piston rod, thereby reducing the contact area between the piston rod, the noise reducer, and the guide hole. This further reduces frictional resistance. When the piston rod reciprocates under the action of the vibration assembly, it drives the noise reducer to roll back and forth along the guide hole. Through this rolling contact, the frictional noise generated between the piston rod and the noise reducer, as well as between the noise reducer and the guide hole, is further reduced, thus providing a better user experience.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1 to 3 As shown, this embodiment provides a low-noise fascia gun, including:

[0031] The machine body 2 contains a vibration assembly and a piston rod 22, and an external massage head 23. One end of the piston rod 22 is connected to the output end of the vibration assembly, and the other end of the piston rod 22 extends out of the machine body 2 and is connected to the massage head 23. A guide sleeve 24 is provided at one end of the machine body 2 near the massage head 23. The guide sleeve 24 has a guide hole 241, through which the piston rod 22 passes. Specifically, the guide hole 241 is a through hole extending from front to back.

[0032] The noise reduction device 1 is sleeved on the piston rod 22 and located between the inner wall of the guide hole 241 and the outer wall of the piston rod 22. The noise reduction device 1 includes a plurality of noise reduction beads 11, which are connected in series to form an annular noise reduction device 1 by an elastic connector 12. The noise reduction device 1 makes point contact with the outer wall of the piston rod 22 on its inner side in the circumferential direction, and makes point contact with the inner wall of the guide hole 241 on its outer side in the circumferential direction.

[0033] When the vibration assembly drives the piston rod 22 to move back and forth, since the noise reduction device 1 is sleeved on the piston rod 22, the piston rod 22 will drive the noise reduction device 1 to move back and forth. When the noise reduction device 1 moves back and forth, the noise reduction bead 11 rolls forward or backward, thereby reducing the friction between the outer wall of the piston rod 22 and the inner wall of the guide hole 241.

[0034] In this embodiment, as Figures 1 to 3 As shown, in order to make the guiding effect of the noise reduction device 1 on the piston rod 22 more stable and balanced, a number of noise reduction beads 11 are arranged at equal intervals in the circumferential direction of the noise reduction device 1. The specific number of noise reduction beads 11 can be set as needed.

[0035] In this embodiment, the elastic connector 12 includes several segments disposed between each pair of adjacent noise-reducing beads 11. The several segments of the elastic connector 12 connect all the noise-reducing beads 11 in series to form a ring-shaped noise reducer 1.

[0036] Among them, such as Figures 1 to 3 As shown, to facilitate the installation and processing of the noise reducer 1, several noise-reducing beads 11 and all the elastic connectors 12 are integrally formed. The integral forming arrangement facilitates the fitting of the noise reducer 1 onto the piston rod.

[0037] In this embodiment, the noise-reducing bead 11 has a through hole in the middle, and the elastic connector 12 can also be an elastic band, which passes through all the through holes of the noise-reducing beads 11 in sequence.

[0038] In this embodiment, the noise reduction bead 11 is preferably spherical in shape, which facilitates rolling relative to the outer wall of the piston rod 22 or the inner wall of the guide hole 241.

[0039] In this embodiment, as Figures 1 to 3As shown, the body 2 has a fixed groove, and the guide sleeve 24 is disposed in the fixed groove. Specifically, the guide sleeve 24 is fixedly disposed in the fixed groove. The guide sleeve 24 has a front wall located in front of the guide hole 241 and a rear wall located behind the guide hole 241. The noise reducer 1 is located between the front wall and the rear wall, and the distance between the front wall and the rear wall can be set to be slightly larger than the diameter of the noise reducing bead 11. Specifically, when the vibration assembly drives the piston rod 22 to move back and forth, the piston rod 22 moves back and forth relative to the noise reducer 1, or the piston rod 22 drives the noise reducer 1 to move back and forth along the inner sidewall of the guide hole 241. The back and forth movement of the noise reducer 1 is the rolling of the noise reducing bead 11 relative to the inner sidewall of the guide hole 241 and the outer sidewall of the piston rod 22. Through rolling contact, friction is reduced, and working noise is lowered.

[0040] In this embodiment, the vibration assembly includes a vibration motor 25, an eccentric wheel 26, and a connecting rod 21. The output shaft of the vibration motor 25 is connected to the input end of the eccentric wheel 26, the output end of the eccentric wheel 26 is connected to the input end of the connecting rod 21, and the output end of the connecting rod 21 is connected to the piston rod 22. Thus, when the vibration motor 25 starts running, the piston rod 22 is driven to reciprocate along the guide sleeve 24 via the eccentric wheel 26 and the connecting rod 21.

[0041] In this embodiment, the noise reducer 1 is preferably made of silicone. Because silicone has a certain degree of elasticity, it can provide elastic shock absorption when the piston rod 22 reciprocates along the guide hole 241, further reducing operating noise.

[0042] Working principle explanation:

[0043] When the piston rod 22 moves back and forth relative to the guide sleeve 24 under the action of the vibration component, the piston rod 22 will move back and forth relative to the noise reducer 1, or the piston rod 22 will drive the noise reducer 1 to move back and forth along the guide hole 241. The back and forth movement of the noise reducer 1 is achieved by the rolling of the noise reduction bead 11. The noise reduction bead 11 reduces the friction force by rolling with the inner side wall of the guide hole 241 and the outer side wall of the piston rod 22, and the friction noise generated is further reduced.

[0044] This utility model is not limited to the above-mentioned optional embodiments. Under the premise of non-contradiction, the various solutions can be combined arbitrarily. Anyone can derive other forms of products under the guidance of this utility model. However, no matter what changes are made in their shape or structure, all technical solutions that fall within the scope of the claims of this utility model are within the protection scope of this utility model.
