Description

Technical Field

[0001] The utility model relates to the technical field of physical therapy and health care, in particular to a negative ion physical therapy instrument. Background Art

[0002] As people's demand for quality of life increases, negative ion therapy devices are becoming more and more popular. Through the combination of negative ion emitters and therapy instruments, negative ion therapy devices not only have the functions of improving sleep, relieving fatigue, killing germs, and improving immunity, but also have the effects of analgesia, improving the metabolism of diseased tissues, and promoting the healing of ulcers and wounds.

[0003] For example, the Chinese utility model patent with publication number CN206404029U and name Negative Ion Therapy Device, in this patent scheme, through the combination of a negative ion generator, a heater and drugs, not only achieves the effect of fumigation and heat therapy, but also plays a role in killing bacteria.

[0004] However, after a lot of experiments and research, the following problems were found:

[0005] First, the amount of negative ions generated in current handheld or small negative ion therapy devices is generally small, and the effect is limited. The main reason is that the negative ion generator works by using high-voltage electric field corona discharge, and the electromagnetic interference generated by its inverter circuit is very harmful to the electrical components close to it. The amount of negative ions generated is proportional to the voltage. Once the amount of negative ions increases, the electromagnetic interference generated increases, and the heater, circuit board and other electrical components in the negative ion therapy device will soon be broken down and damaged. This problem leads to the fact that although the existing handheld or small negative ion therapy devices have the advantages of small size, easy use and carrying, the therapeutic efficacy is greatly reduced.

[0006] Second, although the amount of negative ions generated by the floor-standing or suspended medium and large negative ion therapy devices currently used in most indoor places can meet the requirements, the large distance between the negative ion generator and the heater causes the device to have a long depth, which is not only inconvenient to transport, but also difficult to store when not in use, and takes up a lot of space.

[0007] In summary, it is very necessary to invent a negative ion therapy device that generates sufficient negative ions and is easy to carry, transport and store. Utility Model Content

[0056] In order to further reduce the depth of the negative ion therapy device in this embodiment when the telescopic cylinder 21 is extended relative to the lower shell 1 (working state), reduce the occupied space and improve practicality, the negative ion emission plate 3 is installed on the lower shell 1 through four linked telescopic mechanisms 7, each linked telescopic mechanism 7 is installed corresponding to a wedge block 2101, and the negative ion emission plate 3 is close to the through hole on the lower shell 1 when the telescopic cylinder 21 is extended relative to the lower shell 1, and is away from the through hole on the lower shell 1 when the telescopic cylinder 21 is retracted relative to the lower shell 1; specifically: the linked telescopic mechanism 7 includes an upper fixed block 71, an upper connecting rod 72, a lower connecting rod 73, a lower fixed block 74, a reset spring 75 and a push shaft 76; in this embodiment, the upper fixed block 71, the upper connecting rod 72, the lower connecting rod 73, the lower fixed block 74 and the push shaft 76 The moving shaft 76 is made of polyetheretherketone (PEEK) with good high temperature resistance and flame retardancy, the second reset spring 75 is a high temperature resistant spring, and the surface is sprayed with at least one layer of high temperature resistant insulating paint; the upper connecting rod 72 and the lower connecting rod 73 are rotatably connected through the driving shaft 76, and the other ends of the upper connecting rod 72 and the lower connecting rod 73 are rotatably connected with the upper fixed block 71 and the lower fixed block 74 respectively; the upper fixed block 71 is fixedly connected to the negative ion emission plate 3, and the lower fixed block 74 is fixedly installed with the lower shell 1; the second reset spring 75 is installed between the upper connecting rod 72 and the lower connecting rod 73, and the second reset spring 75 is a tension spring, which extends the emission end on the negative ion emission plate 3 into the through hole of the lower shell 1 without external force; the wedge block 2101 intermittently pushes the driving shaft 76 toward the center direction of the lower shell 1 under the action of the telescopic electric cylinder 22.

Embodiment 2:

[0060] like Fig.16 As shown, this embodiment is a floor-standing or hanging medium-to-large negative ion therapy device. The difference between this embodiment and the first embodiment is that: the power control module 5 is integrated on the power cord (similar in style to the power cord of a laptop computer), and is not in the retractable space formed by the lower shell 1, the telescopic cylinder mechanism 2 and the upper shell 6; the fan 8 is installed on the inner side of the upper shell 6 through a connecting rod; the reason and advantage of this design is that since the power control module 5 of the medium-to-large negative ion therapy device is relatively large in size, placing it outside the retractable space is conducive to reducing the depth of the large negative ion therapy device in this embodiment when the telescopic cylinder 21 is extended relative to the lower shell 1 (working state), reducing the occupied space and improving practicality;

[0063] Usage steps and working principle:

[0064] The first step is to connect the power supply, point the lower housing 1 of the negative ion therapy device to the affected area, and wear the conductive contact bracelet 9 on the user's wrist;

[0065] In the second step, the switch key 62 is pressed. Under the control of the power control module 5, the telescopic electric cylinder 22 is first extended, and the telescopic tube 21 drives the far-infrared heating plate 4, the power control module 5 and the upper shell 6 to extend out of the lower shell 1. The negative ion emitting plate 3 is pushed into the expanded protective cover 11 of the lower shell 1 by the linkage telescopic mechanism 7; thereafter, the negative ion generator and the negative ion converter work, and release negative ions through the negative ion emitting plate 3, and the far-infrared heating plate 4 and the fan 8 also work at the same time, and the heat generated by the far-infrared heating plate 4 and the negative ions released by the negative ion emitting plate 3 are sent out of the lower shell 1 under the wind force of the fan 8;

[0066] Step 3: When the treatment temperature needs to be adjusted, adjust it through the two temperature adjustment keys 63;

[0067] The fourth step is to press the power button 62 when it is necessary to shut down the device. Under the control of the power control module 5, the negative ion generator and the negative ion converter start working, and the negative ion emitting plate 3 and the far-infrared heating plate 4 stop working at the same time; then the fan 8 continues to work for the set time to ensure that the temperature of the entire negative ion therapy device reaches a normal range; finally, the telescopic electric cylinder 22 retracts, and the telescopic tube 21 drives the far-infrared heating plate 4, the power control module 5 and the upper shell 6 to retract into the lower shell 1.
