[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0042] Embodiment 1

[0043] Reference Figures 1 to 5 The essential oil automatic supply device in this embodiment includes an essential oil bottle positioning assembly 10, a hollow first puncture needle 132, a hollow second puncture needle 134 and a gas injection component 20, wherein the essential oil bottle positioning assembly 10 is used to position the essential oil bottle 1. The essential oil bottle positioning assembly 10 includes a positioning groove 111 for placing the essential oil bottle 1. The first puncture needle 132 is arranged at the bottom of the positioning groove 111, the head end of the first puncture needle 132 extends into the positioning groove 111, and a first puncture portion 1321 that can penetrate the essential oil bottle cap 12 is provided at the end. The second puncture needle 134 is arranged at the bottom of the positioning groove 111, the head end of the second puncture needle 134 extends into the positioning groove 111, and a second puncture portion 1341 that can penetrate the essential oil bottle cap 12 is provided at the end, and the tail end of the second puncture needle 134 is connected to one end of the output channel 135. The gas outlet of the gas injection component 20 is connected to the tail end of the first puncture needle 132 through the connecting tube 133 , and is used to inject gas into the essential oil bottle 1 through the first puncture needle 132 .

[0044] Before using the above-mentioned automatic essential oil supply device, the essential oil bottle cap 12 filled with essential oil is inserted downward into the positioning groove 111. During the insertion process, the piercing portion 1321 of the first puncture needle 132 and the second puncture needle 134 punctures the bottle cap of the essential oil bottle 1 and then inserts into the essential oil bottle 1. When it is necessary to supply essential oil, the gas injection component 20 works, and the gas injection component 20 injects gas into the essential oil bottle 1 through the first puncture needle 132. At this time, the pressure in the essential oil bottle 1 increases. When the pressure is greater than the external pressure, the essential oil in the essential oil bottle 1 enters the output channel 135 through the second puncture needle 134, and then is discharged through the oil outlet of the output channel 135, so as to achieve the purpose of automatically supplying essential oil. By controlling the gas output, the output of essential oil can be accurately controlled. In addition, when the essential oil is exhausted, the essential oil bottle can be easily taken out and replaced with a new one, so that quick replacement is achieved, which is very convenient to use.

[0045] In one embodiment, the center line of the first puncture needle 132 and the center line of the second puncture needle 134 are substantially parallel to the center line of the positioning groove 111. In this design, the center line of the first puncture needle 132 and the second puncture needle 134 are substantially perpendicular to the essential oil bottle cap 12, and can effectively and accurately penetrate the essential oil bottle cap 12, avoiding the problem of poor puncture effect and oil leakage caused by the existence of an inclined angle.

[0046] In one embodiment, the head opening of the first puncture needle 132 is higher than the head opening of the second puncture needle 134. This design prevents the air injected from the head opening of the first puncture needle 132 from being directly sucked away from the head opening of the second puncture needle 134, affecting the oil supply effect. It can be understood that the essential oil bottle 1 is placed with the bottle mouth facing downward in the positioning groove 111, and the first puncture needle 132 is relatively long. After being inserted into the essential oil bottle 1, it is located at the bottom of the bottle of the essential oil bottle 1. When air enters the essential oil bottle 1 through the first puncture needle 132, it is directly located at the bottom of the bottle, preventing air from contacting the second puncture needle 134. The second puncture needle 134 is relatively short. After being inserted into the essential oil bottle 1, it is located at the bottle mouth of the essential oil bottle 1, which facilitates the discharge of the essential oil below and avoids waste.

[0047] Reference Figures 1 to 5 The gas injection component 20 includes a piston assembly 21 and a piston drive assembly 22. The output end of the piston assembly 21 is connected to the puncture needle fixing block 13. The output end of the piston drive assembly 22 is connected to the piston assembly 21. The piston drive assembly 22 is used to drive the piston assembly 21 to move.

[0048] It can be understood that the piston drive assembly 22 drives the piston assembly 21 to output gas into the essential oil bottle 1. By driving the piston assembly 21 to accurately output gas, the output amount of the essential oil can be accurately controlled.

[0049] Reference Figures 1 to 5 The piston assembly 21 includes a mounting plate 211, a piston cylinder 212, a piston ring 213 and a connecting column 214. The mounting plate 211 is arranged on one side of the essential oil bottle fixing assembly 10. The piston cylinder 212 is arranged on the mounting plate 211. The piston ring 213 is movably arranged in the piston cylinder 212. The connecting column 214 is arranged on the piston ring 213.

[0050] It can be understood that the gas in the piston cylinder 212 is pushed into the essential oil bottle 1 by the piston ring 213, thereby increasing the pressure in the essential oil bottle 1 and causing the essential oil to be discharged.

[0051] Reference Figures 1 to 5 The piston driving assembly 22 includes a driving motor 221 and an output screw 222. The driving motor 221 is disposed on the mounting plate 211. The output screw 222 is disposed at the output end of the driving motor 221. The output screw 222 is screwed on the connecting column 214.

[0052] It is understandable that by driving the output screw 222 to rotate a certain number of times by the driving motor 221, the moving distance of the piston ring 213 can be calculated by the pitch of the output screw 222, and then the amount of gas output to the essential oil bottle 1 can be calculated. Accurately determine the amount of essential oil output.

[0053] Reference Figures 1 to 5The piston driving assembly 22 further includes a distance sensing device 215. The distance sensing device 215 is disposed on the mounting plate 211 and is located above the piston ring 213. The distance sensing device 215 is electrically connected to the driving motor 221. The distance sensing device 215 is used to sense the stroke of the piston ring 213.

[0054] It is worth noting that, in order to prevent sudden power failure, in some embodiments of the present invention, a distance sensing device for detecting the position of the piston ring 213 is provided. When the piston ring 213 moves to the bottom of the piston cylinder 212, the driving motor 221 stops rotating.

[0055] Furthermore, in the embodiment of the present utility model, the essential oil bottle cap 12 is a rubber sealing plug.

[0056] It is worth mentioning that the rubber sealing plug can prevent the essential oil from leaking from the gap between the first puncture needle 132 and the second puncture needle 134.

[0057] As an alternative, the gas injection component 20 is an air pump. The connecting tube 133 connects the first puncture needle 132 and the air pump. The output channel 135 is provided with an oil valve 136, and the oil valve 136 is electrically connected to the air pump.

[0058] It is worth noting that in some other embodiments of the present invention, in order to reduce costs, the essential oil bottle 1 can also be pressurized by an air pump, and then the discharge of the essential oil is controlled by the oil valve 136, and the discharge of the essential oil can also be monitored and controlled by a flow meter.

[0059] Embodiment 2

[0060] Reference Figures 6 to 10 As shown in the figure, the essential oil automatic supply device in one embodiment of the utility model comprises: an essential oil bottle positioning assembly 10, a hollow first puncture needle 132, a hollow second puncture needle 134 and an essential oil delivery mechanism 30, the essential oil bottle positioning assembly 10 comprises a positioning groove 111 for placing the essential oil bottle 1; the first puncture needle 132 is arranged at the bottom of the positioning groove 111, the head end of the first puncture needle 132 extends into the positioning groove 111, and a puncture portion 1321 that can penetrate the essential oil bottle cap 12 is provided at the end, the first puncture needle 132 The tail end of the essential oil delivery mechanism 30 is connected to one end of the air inlet channel 40, and the other end of the air inlet channel 40 is connected to the outside world; the second puncture needle 134 is arranged at the bottom of the positioning groove 111, the head end of the second puncture needle 134 extends into the positioning groove 111, and a piercing portion 1321 that can penetrate the essential oil bottle cap 12 is provided at this end; the input port of the essential oil delivery mechanism 30 is connected to the tail end of the second puncture needle 134, and the output port is connected to one end of the output channel 135, which is used to guide the essential oil in the essential oil bottle 1 into the output channel 135 through the second puncture needle 134.

[0061] Before using the above-mentioned automatic essential oil supply device, the essential oil bottle cap 12 filled with essential oil is inserted into the positioning groove 111. During the insertion process, the piercing parts 1321 of the first puncture needle 132 and the second puncture needle 134 pierce the essential oil bottle cap 12 and then insert into the essential oil bottle. When the essential oil needs to be supplied, the essential oil delivery mechanism 30 works, and the essential oil delivery mechanism 30 guides the essential oil in the essential oil bottle 1 through the second puncture needle 134 into the output channel 135, so as to achieve the purpose of automatic supply of essential oil. By controlling the speed of the essential oil delivery mechanism 30, the output amount of the essential oil can be accurately controlled.

[0062] In one embodiment, the center line of the first puncture needle 132 and the center line of the second puncture needle 134 are substantially parallel to the center line of the positioning groove 111. In this design, the center line of the first puncture needle 132 and the second puncture needle 134 are substantially perpendicular to the essential oil bottle cap 12, and can effectively and accurately penetrate the essential oil bottle cap 12, avoiding poor puncture effect caused by angle problems.

[0063] refer to Fig.10 In one embodiment, the head end opening 1322 of the first puncture needle 132 is higher than the head end opening 1342 of the second puncture needle 134. This design can achieve smooth flow of gas, improve the effect of inflation, and also reduce the impact on the essential oil, thereby ensuring the quality of the essential oil. Preferably, the head end opening 1322 of the first puncture needle 132 is located on the side wall of the first puncture needle 132 close to the piercing portion 1321, and the head end opening 1342 of the second puncture needle 134 is located on the side wall of the second puncture needle 134 close to the piercing portion 1341. The head end opening 1322 and the head end opening 1342 adopt this design, so that when the piercing portion 1321 of the first puncture needle 132 and the piercing portion 1341 of the second puncture needle 134 puncture the bottle cap 12 of the essential oil bottle, it can prevent the debris of the bottle cap 12 from blocking the head end opening 1322 and the head end opening 1342.

[0064] In order to prevent the essential oil from being discharged from the air inlet passage 40, a one-way valve is provided on the air inlet passage 40. The one-way valve may be an air check valve. The air check valve can only take in air but cannot let out air. When the essential oil delivery mechanism 30 works, the essential oil in the essential oil bottle 1 is pumped out of the bottle, a vacuum is formed in the essential oil bottle 1, and the outside air is replenished into the essential oil bottle 1 through the one-way valve.

[0065] Preferably, the essential oil delivery mechanism 30 is a peristaltic pump, which is conducive to continuous and uniform delivery of the essential oil.

[0066] Reference Fig.11As an example, the essential oil bottle positioning assembly 10 includes a positioning member body 11 and a puncture needle fixing block 13, the positioning member body 11 is provided with a positioning groove 111, and the bottom of the positioning member body 11 is provided with a first through hole 112 and a second through hole 113, the puncture needle fixing block 13 is fixed below the positioning member body 11, the first puncture needle 132 and the second puncture needle 134 are both fixed on the puncture needle fixing block 13, and pass through the first through hole 112 and the second through hole 113 respectively. Preferably, the puncture needle fixing block 13 includes a first fixing block 137 and a second fixing block 138. A side surface of the first fixing block 137 is provided with two semicircular first grooves 1371 and second grooves 1372 arranged side by side. A side surface of the second fixing block 138 is correspondingly provided with semicircular third grooves 1381 and fourth grooves 1382. The first fixing block 137 and the second fixing block 138 are buckled together. The first groove 1371 and the third groove 1381 are combined to form a first positioning hole for fixing the first puncture needle 132. The second groove 1372 and the fourth groove 1382 are combined to form a second positioning hole for fixing the second puncture needle 134. This design has high positioning accuracy, can ensure that the center line of the first puncture needle 132, the center line of the second puncture needle 134 is roughly parallel to the center line of the positioning groove 111, and is easy to assemble.

[0067] Also refer to Figure 3 and Figure 7 In the first embodiment and the second embodiment, the essential oil automatic supply device further comprises a heating component 15 for heating the essential oil in the essential oil bottle. In this way, during winter massage, the heated essential oil drips onto the human skin, making the human body feel comfortable.

[0068] In one embodiment, the heating component 15 includes a PTC ceramic heating plate, and a mounting groove matching the PTC ceramic heating plate is provided on one side of the essential oil bottle positioning component 10, and the PTC ceramic heating plate is embedded in the mounting groove. The PTC ceramic heating plate has a high-temperature self-protection function, and even if the temperature sensor temperature control fails, it can ensure that the soup will not hurt people.

[0069] In another embodiment, a physical therapy tool head (including but not limited to a massage tool head, a fascia gun tool head, and a radio frequency tool head) is provided, and the physical therapy tool head has the automatic essential oil supply device in the above embodiment.

[0070] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
