Description

Technical Field

[0001] This utility model relates to the field of fascia gun equipment technology, and in particular to a handheld fascia gun with an essential oil leak-proof structure. Background Technology

[0002] The handheld fascia gun with an essential oil leak-proof structure is a portable massage device that combines muscle relaxation and essential oil care. Based on the high-frequency vibration massage of traditional handheld fascia guns, it integrates an essential oil storage, export, and leak-proof system. It can simultaneously and evenly apply essential oil to the skin during the massage, and promote the penetration of essential oil through vibration, achieving the dual effect of relaxing muscles and nourishing the skin. It can be used in post-exercise recovery and daily health care scenarios, which not only simplifies the steps of applying essential oil separately, but also improves the absorption efficiency of essential oil through mechanical vibration.

[0003] Early devices of this type consisted of a basic fascia gun and an external essential oil application device. Essential oil was pre-applied to the skin using a separate dropper or sprayer before the fascia gun was used for massage. This structure had significant drawbacks. First, the amount of essential oil applied was difficult to control, resulting in an oily feeling due to excessive application, and excess oil would also stain clothing, causing waste. Second, the small contact area of ​​the massage head meant that the pre-applied essential oil would accumulate in localized areas, especially in small areas such as joints and acupoints, causing skin irritation or discomfort. To solve these problems, current devices have begun to adopt a structure with an internal oil storage chamber and oil guiding channels. Essential oil is discharged through holes on the surface of the massage head, avoiding the tediousness of separate application. However, the existing structure still has shortcomings. It usually relies on gravity or simple mechanical pressure to make the essential oil flow out. When the fascia gun vibrates at high speed, the essential oil in the oil guiding channels is prone to uneven flow due to vibration inertia. When the massage head moves quickly, localized areas may still experience oil accumulation due to the instantaneous oil output exceeding the contact area's capacity, leading to skin discomfort.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 4 and Figure 5 An embodiment of this utility model is provided: a handheld fascia gun with an essential oil leak-proof structure, including a gun body 1 and a chuck 4. A control component 5 is provided on the rear side of the gun body 1, and a telescopic bending mechanism 3 is provided on the outer wall of the gun body 1. The telescopic bending mechanism 3 is used to facilitate massage and holding of the back area. A quantitative application mechanism 2 is provided on the front side of the chuck 4, and a charging component 6 is provided at the bottom of the gun body 1.

[0034] The dispensing mechanism 2 includes a massage head 209, the rear of which is fixedly connected to the front of the chuck 4. An essential oil bottle 201 is threadedly connected to the top of the gun body 1. A corrugated hose 202 is connected to the front of the gun body 1. A connecting pipe 203 is fixedly connected to the rear of the chuck 4. The front end of the connecting pipe 203 communicates with the top of the inner wall of the massage head 209. The high-frequency vibration generated by the gun body 1 causes the piston 208 to move backward due to inertia. At this time, the elastic spring 207 is compressed, providing cushioning for the piston 208 and limiting its excessive backward movement. The backward movement of the piston 208 creates airflow... The essential oil in the essential oil bottle 201 is introduced into the gap area through the passage of the corrugated hose 202 and the connecting pipe 203. A lead screw 204 is rotatably connected to the right side of the chuck 4. An inclined slider 205 is threaded through the left side of the outer wall of the lead screw 204 and passed through the right side of the chuck 4. A conical sliding plate 206 is slidably connected to the outer wall of the inclined slider 205. By rotating the lead screw 204, the inclined slider 205 can be driven to slide along the inner wall of the chuck 4, causing the conical sliding plate 206 to move forward or backward within the massage head 209, thereby changing the preload and compression of the elastic spring 207. The stroke controls the backward movement distance of the piston 208, ultimately adjusting the amount of essential oil discharged. An elastic spring 207 is fixedly connected to the front side of the conical sliding disc 206, and the piston 208 is fixedly connected to the front end of the elastic spring 207. When the direction of vibration inertia changes and the piston 208 moves forward, the elastic force of the elastic spring 207 assists in its return to its original position, squeezing the essential oil in the gap and causing it to seep out evenly from the micro-oil outlet 210. The outer wall of the piston 208 is slidably connected to the inner wall of the massage head 209, and the micro-oil outlet 210 is located in the middle of the front side of the massage head 209. The elastic spring 207 is in a naturally extended state, pushing the piston 208 to fit tightly against the inner wall of the massage head 209, directly sealing the micro oil outlet 210, and at the same time blocking the passage between the essential oil bottle 201 and the inner cavity of the massage head 209, forming a double leak-proof structure. The outer wall of the chuck 4 is provided with a locking component 211; the rear side of the connecting tube 203 is locked with the front side of the corrugated hose 202, and the handle 7 is fixedly connected to the middle of the outer wall of the gun body 1; the outer wall of the conical sliding plate 206 is slidably connected to the inner wall of the massage head 209, and the rear end of the chuck 4 is locked with the front end of the gun body 1.

[0035] The locking assembly 211 includes multiple limiting strips 2111, the outer walls of which are fixedly connected to the rear side of the chuck 4. The bottom front side of the gun body 1 is threaded with a fastening bolt 2112. The locking assembly 211 is double-locked by the limiting strips 2111 and the fastening bolt 2112 to ensure the structural stability of the quantitative application mechanism 2 and the gun body 1. The front side of the massage head 209 is fixedly connected with multiple wear-resistant protrusions 2113. The wear-resistant protrusions 2113 of the massage head 209 enhance the stability of skin contact and assist in massage pressure.

[0036] Specifically, in a static state, the elastic spring 207 is in a naturally extended state, pushing the piston 208 to fit tightly against the inner wall of the massage head 209, directly sealing the micro oil outlet 210, and simultaneously blocking the passage between the essential oil bottle 201 and the inner cavity of the massage head 209, forming a double leak-proof structure. When in use, the high-frequency vibration generated by the gun body 1 causes the piston 208 to move backward due to inertia. At this time, the elastic spring 207 is compressed, providing a buffer for the piston 208 and limiting its excessive backward movement. The gap created by the backward movement of the piston 208, through the passage between the corrugated hose 202 and the connecting pipe 203, introduces the essential oil from the essential oil bottle 201 into the gap area. When the direction of vibration inertia changes and the piston 208 moves forward, the elastic spring 207... Force assists in its reset, squeezing the essential oil in the gap, so that the essential oil seeps out evenly from the micro oil outlet 210. At the same time, by rotating the lead screw 204, the tilting slider 205 can be driven to slide along the inner wall of the chuck 4, causing the conical sliding disc 206 to move forward or backward in the massage head 209, thereby changing the preload and compression stroke of the elastic spring 207, controlling the backward movement distance of the piston 208, and finally realizing the adjustment of the amount of essential oil discharged, avoiding waste or skin discomfort caused by excessive oil discharge. The wear-resistant protrusions 2113 of the massage head 209 enhance the stability of skin contact and assist in massage pressure. The locking component 211 is double-locked by the limit strip 2111 and the fastening bolt 2112 to ensure the structural stability of the quantitative application mechanism 2 and the gun body 1.

[0037] Reference Figure 1 , Figure 2 and Figure 6 The telescopic bending mechanism 3 includes two clamping plates 301. The adjacent sides of the two clamping plates 301 are located on the left and right sides of the outer wall of the gun body 1. Limiting rods 302 are fixedly connected to the upper and lower ends of the adjacent sides of the two clamping plates 301, clamping the two clamping plates 301 to both sides of the outer wall of the gun body 1 via the limiting rods 302, forming a stable clamping. A sliding hollow column 303 is slidably connected to the middle of the inner wall of each of the two clamping plates 301. A hollow plate 304 is fixedly connected to the rear side of each of the two clamping plates 301. A pressing plate 305 is threadedly connected to the inner wall of the sliding hollow column 303. The rear side of the outer wall of the pressing plate 305 engages with the outer wall of the pressing plate 305. Rotating the pressing plate 305... The sliding hollow column 303 is moved along the inner wall thread of the sliding hollow column 303, pushing the sliding hollow column 303 to engage with the rear side of the gun body 1. The squeezing block 305 can be locked in this position by rotating it again. The bottom of the adjacent side of the two clamping plates 301 is rotatably connected to a rotating rod 306. The right side of the rotating rod 306 passes through the outer wall of the right clamping plate 301 and is threadedly connected to an adjustment knob 307. Rotating the rotating rod 306 can change the angle between the gun body 1 and the clamping plate 301 to adapt to the massage angle requirements of different areas of the back. After the angle is determined, the rotating rod 306 is locked by tightening the adjustment knob 307 to prevent the angle from shifting due to vibration. A telescopic component 308 is provided on the front side of the outer wall of the rotating rod 306.

[0038] The telescopic assembly 308 includes an anti-slip sleeve 3081. The inner wall of the anti-slip sleeve 3081 is slidably connected to the front side of the outer wall of the rotating rod 306. A hollow threaded sleeve 3082 is fixedly connected to the rear end of the anti-slip sleeve 3081. A locking ring 3083 is threadedly connected to the outer wall of the hollow threaded sleeve 3082. Rotating the locking ring 3083 can release the hollow threaded sleeve 3082 from clamping the rotating rod 306, push the anti-slip sleeve 3081 to slide along the outer wall of the rotating rod 306 to the required length, and then rotate the locking ring 3083 in the opposite direction to fix the position, extending the operating radius to reach the deep area of ​​the back.

[0039] Specifically, when a back massage is needed, first, the two clamps 301 are engaged with the outer walls of the gun body 1 by the limiting rod 302 to form a stable clamp. Rotate the squeezing block 305 to move it along the inner thread of the sliding hollow column 303, pushing the sliding hollow column 303 to engage with the rear side of the gun body 1. Rotate the squeezing block 305 again to lock the position, ensuring a stable connection between the mechanism and the gun body 1. When adjusting the angle, rotate the rotating rod 306 to change the angle between the gun body 1 and the clamps 301, adapting to the massage angle requirements of different areas of the back. After the angle is determined, tighten the adjusting knob 307 to lock the rotating rod 306 to prevent vibration from causing angle deviation. If the operating length needs to be adjusted, rotate the locking ring 3083 to release the clamping of the hollow threaded sleeve 3082 on the rotating rod 306, push the anti-slip sleeve 3081 to slide along the outer wall of the rotating rod 306 to the required length, and then rotate the locking ring 3083 in the opposite direction to fix the position, extending the operating radius to reach the deep areas of the back.

[0040] Reference Figure 3 and Figure 5 The control component 5 includes a switch button 501, which is fixedly connected to the rear end of the gun body 1. The switch button 501 can control the start of the gun body 1. Multiple indicator lights 502 are fixedly connected to the top rear side of the gun body 1. The indicator lights 502 will display the working status of the device in real time. The charging component 6 includes a charging interface 601, which is opened on the outer wall of the charging interface 601 at the bottom of the gun body 1. The charging interface 601 is connected to a power source for charging. A status light 602 is fixedly connected to the bottom right side of the gun body 1. The status light 602 will display the charging progress.

[0041] Specifically, in the control component 5, the switch button 501 can control the start of the gun body 1, while the indicator light 502 will display the working status of the device in real time, so that the user can keep track of the operation. In the charging component 6, the charging interface 601 is connected to the power supply for recharging, and the status light 602 will display the charging progress to ensure that the device is always available.

[0042] Working principle: First, under static conditions, the elastic spring 207 is in a naturally extended state, pushing the piston 208 to fit tightly against the inner wall of the massage head 209, directly sealing the micro oil outlet 210, and simultaneously blocking the passage between the essential oil bottle 201 and the inner cavity of the massage head 209, forming a double leak-proof structure. During use, the high-frequency vibration generated by the gun body 1 causes the piston 208 to move backward due to inertia. At this time, the elastic spring 207 is compressed, providing a buffer for the piston 208 and limiting its excessive backward movement. The gap created by the backward movement of the piston 208, through the passage of the corrugated hose 202 and the connecting pipe 203, allows the essential oil bottle 201 to pass through. The essential oil is introduced into the gap area. When the direction of vibration inertia changes and the piston 208 moves forward, the elastic spring 207 assists in its reset, squeezing the essential oil in the gap and causing it to seep out evenly from the micro oil outlet 210. At the same time, by rotating the screw 204, the tilting slider 205 can be driven to slide along the inner wall of the chuck 4, causing the conical sliding disc 206 to move forward or backward in the massage head 209, thereby changing the preload and compression stroke of the elastic spring 207, controlling the backward movement distance of the piston 208, and finally adjusting the amount of essential oil discharged, avoiding waste or skin discomfort caused by excessive oil discharge.

[0043] Furthermore, through the telescopic bending mechanism 3, when a back massage is needed, the two clamping plates 301 are first engaged with the outer walls of the gun body 1 by means of the limiting rod 302, forming a stable clamping state. Then, the pressing plate 305 is rotated, causing it to move along the inner thread of the sliding hollow column 303, pushing the sliding hollow column 303 to engage with the rear side of the gun body 1. Rotating the pressing plate 305 again locks the position, thus ensuring a stable connection between the mechanism and the gun body 1. When adjusting the angle, rotating the rotating rod 306 can change the angle between the gun body 1 and the clamping plate. The angle between the plates 301 is adjusted to accommodate the massage angle requirements of different areas of the back. After the angle is determined, the rotating rod 306 is locked by tightening the adjustment knob 307 to prevent the angle from shifting due to vibration. If the operating length needs to be adjusted, the locking ring 3083 can be rotated to release the hollow threaded sleeve 3082 from clamping the rotating rod 306, and the anti-slip sleeve 3081 can be pushed to slide along the outer wall of the rotating rod 306 to the required length. Then, the locking ring 3083 is rotated in the opposite direction to fix the position, thereby extending the operating radius to reach deeper areas of the back.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
