The disclosure relates to a light therapy device, and in particularly, to a light therapy device with a function of releasing negative ion.
A light therapy device utilizes a light emitting unit to emit light which can relax uncomfortable part of a human body for light therapy.
The inventor of the disclosure studies to associate a light therapy device and a negative ion device with a negative-pressure cup, so that a surface of the uncomfortable part of a patient's body can be sucked to form a bulge by sucking air in the cup to form a negative-pressure status in the negative-pressure cup, meanwhile, the light therapy device and the negative ion device can perform light therapy and negative ion attachment to the bulge. Thus, it has a better relaxation effect to the patient's uncomfortable part.
However, the negative ion device must use a releasing needle to release negative ions, and the bulge on the patient's uncomfortable part, which is formed by suction of the negative-pressure cup, protrudes toward the releasing needle. Experiments have confirmed that the bulge is often stabbed by the releasing needle, which may cause the risk of infection.
Therefore, how to design a combination of light therapy, negative ions, and a negative-pressure cup with preventing a patient's bulge from being stabbed by a releasing needle is an important issue.
In view of this, the inventors have devoted themselves to the above-mentioned related art, researched intensively and cooperated with the application of science to try to solve the above-mentioned problems.
An object of the disclosure is to provide a light therapy device with a function of releasing negative ion, which may combine a light therapy assembly and a negative ion assembly with a negative-pressure cup for usage, and use a needle protection cap to prevent a patient's bulge from being stabbed by a releasing needle.
To accomplish the above object, the disclosure provides a light therapy device with a function of releasing negative ion and used for a negative-pressure cup. The light therapy device includes a carrier, a light therapy assembly, a negative ion assembly and a needle protection cap. The carrier is disposed in the negative-pressure cup and includes a panel. The light therapy assembly is disposed in the carrier. The negative ion assembly is disposed in the carrier and includes a releasing needle. The releasing needle projects out from the panel to release negative ions. The needle protection cap covers the panel corresponding to the releasing needle to shield the releasing needle.
In comparison with the related art, the disclosure has the following functions. The light therapy assembly and the negative ion assembly may be incorporated with the negative-pressure cup, and a needle protection cap is used to prevent a patient's bulge from being stabbed by a releasing needle.
The technical contents of this disclosure will become apparent with the detailed description of embodiments accompanied with the illustration of related drawings as follows. It is intended that the embodiments and drawings disclosed herein are to be considered illustrative rather than restrictive.
The disclosure provides a light therapy device with a function of releasing negative ion, as shown in
As shown in
The carrier 1 may be any structure capable of being disposed in the negative-pressure cup 900 and have a panel 15 in a light-permeable manner. The shown embodiment uses the carrier 1 having a base 1a and a light-permeable cover 1b as an example. The base 1a and the light-permeable cover 1b may be assembled with each other.
The base 1a has an opening 13 as shown in
The light therapy assembly 2 is disposed in the receiving space 1c of the carrier 1 for emitting light via the light-permeable cover 1b (or the panel 15). A patient's uncomfortable part may be relaxed (light therapy) after being irradiated by the light.
The negative ion assembly 3 is also disposed in the receiving space 1c. The negative ion assembly 3 has a releasing needle 321 which projects outside the panel 15 (also outside the carrier 1) to release negative ions.
The needle protection cap 5 covers the panel 15 corresponding to the releasing needle 321 (or position of a needle receiving recess 1512) to make the releasing needle 321 be shielded by the needle protection cap 5 as shown in
As shown in
As shown in
In some embodiments, the panel 15 is further dented with a cap receiving recess 152 toward the same direction with the same manner of the needle receiving recess 1512. The cap receiving recess 152 has a second bottom plate 1521. The receiving cavity 1511 and the needle receiving recess 1512 are dented from the second bottom plate 1521 to make the panel 15, the second bottom plate 1521 and the first bottom plate 1513 form a step shape from the outside to the inside.
The light therapy assembly 2 includes a circuit board 21 and multiple light emitting elements 22 arranged on the circuit board 21. The light emitting element 22 is a light emitting diode (LED) which has a light therapy effect and a wavelength between 415±10 nm and 830±10 nm. For example, the light emitting element 22 may be a green LED with a wavelength of 525±15 nm or 525±30 nm. The light therapy assembly 2 is formed with an escape hole 211 and arranged to be parallel with the panel 15 at an interval so that the post 151 passes through the escape hole 211 and the light therapy assembly 2 emits light toward the panel 15 after the light therapy assembly 2 has been disposed in the carrier 1. The light-permeable cover 1b may further include a shading plate 17 which is assembled on the inner side 15a of the panel 15 with a face-to-face manner. The shading plate 17 is formed with multiple via holes 171 corresponding to each light emitting element 22 so that each light emitting element 22 emits light correspondingly to each via hole 171.
Furthermore, the shading plate 17 is formed with an aperture 173 for being passed by the post 151 and embedded by the protrusion formed by the cap receiving recess 152 dented on the panel 15.
The negative ion assembly 3 includes a negative ion emitter 31 and a negative ion releasing head 32 and may further include a frame 33. The negative ion emitter 31 is fixed in the receiving space 1c by the frame 33. The negative ion releasing head 32 is disposed in the receiving cavity 1511 of the panel 15 and has the releasing needle 321. The releasing needle 321 passes through the through hole 1514 to reach in the needle receiving recess 1512 so that both the negative ion releasing head 32 and the releasing needle 321 may be received in the needle receiving recess 1512.
The needle protection cap 5 has multiple surrounding walls 51 at intervals. The second bottom plate 1521 is formed with an indent 1522 corresponding to the surrounding walls 51. The needle protection cap 5 is fixed in the cap receiving recess 152 and covers the cap receiving recess 152 by embedding the surrounding walls 51 into the indent 1522. As for the manner of fixing the needle protection cap 5 in the cap receiving recess 152, the disclosure does not limit it, for example, it may be that an outer periphery of the needle protection cap 5 tightly abuts against the corresponding inner wall of the cap receiving recess 152, or the surrounding walls 51 are tightly embedded in the indent 1522. The needle protection cap 5 is further formed with multiple passing holes 52 to facilitate spreading negative ions released by the releasing needle 321. The negative ions may also be spread via gaps between every adjacent two of the surrounding walls 51 as shown in
In addition, as shown in
The bottom (not labeled) of the base 1a is formed with a fixing hole 12. The base 1a is further formed with a first corresponding fixing portion 11 corresponding to the fixing hole 12 in position as shown in
The fixing rod 7 has two ends which are a first fixing portion 71 and a second fixing portion 72. The first fixing portion 71 may be a polygonal plate protruding from an outer surface of the rod body (not labeled), and the second fixing portion 72 may be an outer thread formed on the outer surface of the rod body, but not limited to this.
The fixing member 8 has a second corresponding fixing portion 81 which is fixed to the second fixing portion 72. The fixing member 8 may be any component capable of being correspondingly fixed to the second fixing portion 72. In the embodiment, a nut is used as an example. Thus, the second corresponding fixing portion 81 may be an inner thread formed on an inner surface of the fixing member 8 to make the second fixing portion 72 be screwed with the second corresponding fixing portion 81.
The fixing portion 71 of the fixing rod 7 is fixed to the first corresponding fixing portion 11 of the carrier 1. The fixing rod 7 projects out from the carrier 1 through the fixing hole 12 to form a projecting portion as shown in
Therefore, the light therapy device 100 is disposed in the negative-pressure cup 900, and both the panel 15 used for emitting light and the needle protection cap 5 used for spreading negative ions may face a patient's portion to be relaxed.
While this disclosure has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of this disclosure set forth in the claims.
