[0032] The utility model is an intense pulse light therapy device, which not only has the characteristics of fast assembly efficiency, but also has the characteristics of low cost and convenient carrying.

[0033] like Figure 1-6 As shown, this intense pulsed light therapy device includes the following components:

[0034] PCBA board 1, outer frame 2, middle shell 3, front shell 4, upper tail cover 5, lower tail cover 6.

[0035] The middle shell 3 is a structure with a hollow interior and openings at both ends. The PCBA board 1 is located inside the middle shell 3, and its front and rear ends pass through the openings and are located outside the middle shell 3;

[0036] like Figure 4 , 9 As shown in FIG. 10 , the outer frame 2 is in a circuitous semi-enclosed shape, and a first mounting groove 2a extending along the length direction of the middle shell 3 is provided on one side of the outer frame 2. One end of the outer frame 2 is inserted into the first mounting groove 2a, and the other end of the outer frame 2 is against the edge of the other side of the outer frame 2 through the circuit of its own middle part outside the rear end of the middle shell 3, so that the outer frame 2 surrounds the part of the PCBA board 1 passing through the rear end;

[0037] The upper tail cover 5 and the lower tail cover 6 close the upper and lower parts of the rear end of the PCBA board 1, and a clamping structure is provided between them so that the two are clamped and fixed to each other;

[0038] The front end of the PCBA board 1 is covered by the front shell 4 , and the front shell 4 is connected with the middle shell 3 in a snap-fitting manner so that all aspects of the PCBA board 1 are covered.

[0039] It is not difficult to see that the utility model does not need to use screws for fixing, and they are all connected to each other in a snap-fitting form. It can be seen that the utility model can save a lot of production costs. In addition, the use of screws is eliminated, the assembly steps of the product are optimized, and the assembly efficiency can also be significantly improved.

[0040] The design of the middle shell 3 is mainly to combine with the use of the hand strap 7. Figure 1-2It can be seen that the positions of the two ends of the carrying strap 7 are adjacent to the tail cover and the middle shell 3 respectively, that is to say, the length of the carrying strap 7 can be extended to most areas on the side of the intense pulsed light therapy device; based on having a longer carrying strap 7, it is more convenient to control the intense pulsed light therapy device.

[0041] Figure 6-7 It is shown that the inner surface of the outer frame 2 is provided with a block portion 22 with a buckle position 21, the first installation groove 2a extends to the edge of the rear end of the middle shell 3, and the inner surface of the first installation groove 2a is provided with a strip opening 2a'. The outer frame 2 is slidably assembled with the above-mentioned middle shell 3 in the form of the block portion 22 being located in the strip opening 2a', and the buckle position 21 located at the outer end of the block portion 22 is located in the middle shell 3, and the buckle position 21 extends toward the inner circumferential surface of the outer frame 2, and the outer frame 2 is constrained to the first installation groove 2a by the buckle position 21 to prevent the outer frame 2 from falling off from the first installation groove 2a.

[0042] like Figure 5 As shown, the above-mentioned latching structure includes a hook member 61 with a barb 61' and a connector 51 with a first latch. In the present embodiment, the connector 51 is on the inner surface of the upper tail cover 5, and the hook member 61 is on the inner surface of the lower tail cover 6. When the upper tail cover 5 and the lower tail cover 6 close the rear end of the PCBA board 1, the position of the connector 51 and the hook member 61 are opposite to each other. After contacting each other, the plastic deformation produced by each other causes the barb 61' located on the side of the hook member 61 to slide into the first latch located on the side of the connector 51. This latching method can also allow the upper tail cover 5 and the lower tail cover 6 to form a clamping effect, and by clamping the outer frame 2, the outer frame 2 is less likely to fall off.

[0043] like Fig.12 As shown, the outer frame 2 and the hand strap 7 are snap-fitted together, a slot 23 is provided on the side of the outer frame 2, the outer end of the clamping column 24 has a clamping cap 24' extending outward, the clamping column 24 passes through the hand strap 7 and is inserted into the slot 23, and the clamping cap 24' is pressed on the hand strap 7.

[0044] exist Fig.11 In the embodiment, a clamp 31 with a second bayonet is provided on the inner edge of the front end of the middle shell 3, and a clamp block is provided on the inner surface of the front shell 4. After the front shell 4 is sleeved on the front end of the middle shell 3, the clamp block slides into the second bayonet, thereby fixing the front shell 4 on the middle shell 3.

[0045] like Figure 8 , 11, 13, it also includes a bracket 8, the bracket 8 is provided with a plurality of first positioning columns 81, the PCBA board 1 is provided with a positioning kit 100 that cooperates with the first positioning columns 81, the PCBA board 1 is sleeved on the bracket 8 through the positioning kit 100, the bottom surface of the bracket 8 is provided with a sleeve 82, the sleeve 82 corresponds to the second positioning column 62 on the inner surface of the lower tail cover 6, the bracket 8 is fixed to the lower tail cover 6 through the sleeve 82, and the front shell 4 is provided with a second mounting groove 41 adapted to the light emitting area 1a, and the peripheral surface of the light emitting area 1a is against the surrounding of the second mounting groove 41, thereby ensuring that the PCBA board 1 is stable in the middle shell 3.

[0046] The assembly process of the utility model is:

[0047] S1, put the PCBA board 1 on the bracket 8, and then put the bracket 8 into the middle shell 3;

[0048] S2, one end of the outer frame 2 with the buckle position 21 slides into the first installation groove 2a through the block portion 22;

[0049] S3, insert the second positioning column 62 on the lower tail cover 6 into the sleeve 82 on the bracket 8, and then cover the upper tail cover 5 on the upper part of the outer frame 2 accordingly, so that the hook member 61 in the upper tail cover 5 and the connecting member 51 are engaged and fixed with each other.

[0050] S4, the front shell 4 is sleeved on the front end of the middle shell 3 and is fixed with the clamping block through the clamp 31.
