Description

Technical Field

[0001] This utility model relates to the field of hair straightener testing technology, and in particular to an automatic hair straightener testing device. Background Technology

[0002] A hair straightener, as the name suggests, is used to straighten hair. It uses two heating plates to clamp the hair, heat and soften it, and then straighten and cool it to achieve the purpose of straight hair. As people's living standards continue to improve, hair straighteners are becoming more and more popular as a personal care product.

[0003] During the production of hair straighteners, the heating plates need to be temperature-tested. Existing hair straightener testing devices typically place the two heating plates of the hair straightener at two separate temperature sensors and then compare the readings from the two sensors to see if they match. However, in this testing process, the temperature sensors cannot be moved, which limits the range of temperature detection for the heating plates of the hair straightener. This makes it inconvenient to comprehensively test both heating plates on the hair straightener, resulting in low accuracy. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the background art by proposing an automatic detection device for hair straighteners.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic detection device for hair straighteners, comprising:

[0007] A right-angled C-shaped frame mounting bracket and a hair straightener to be tested placed on the right-angled C-shaped frame mounting bracket;

[0008] The control display is fixedly installed on the front side of the right-angled C-shaped frame bracket;

[0009] A detection block is movably disposed inside the hair straightener to be tested. Temperature sensors are fixedly installed on both the front and rear sides of the detection block, and the temperature sensors are electrically connected to the control display.

[0010] The reciprocating assembly includes a through hole at the top of a right-angled C-shaped frame, with support rods slidably passing through both sides of the through hole. A movable internal gear frame is fixedly connected to one end of each of the two support rods. An incomplete gear is provided inside the movable internal gear frame. A drive motor for driving the incomplete gear to rotate is fixedly installed on the front side of the right-angled C-shaped frame. A connecting rod is fixedly installed at the bottom of the movable internal gear frame, and the connecting rod is detachably connected to the detection block.

[0011] Preferably, an electric push rod is fixedly installed on the inner top of the right-angled C-shaped frame fixing bracket, and the drive end of the electric push rod is vertically downward and fixedly installed with a positioning plate.

[0012] Preferably, a stud is fixedly installed on the top of the detection block, a threaded groove is opened at the bottom of the connecting rod, and the threaded groove is threadedly connected to the stud. A conductive sheet is fixedly installed on the top of the threaded groove and the top of the stud.

[0013] Preferably, the longitudinal section of each support rod is rectangular.

[0014] Preferably, racks are fixedly installed on the inner top and inner bottom of the movable inner gear frame, and the racks are engaged or disengaged from the incomplete gear.

[0015] Compared with existing technologies, the advantages of the automatic detection device for hair straighteners provided by this utility model are as follows:

[0016] 1. By controlling the rotation of the incomplete gear through the drive motor, the gear is intermittently meshed with the racks on both sides of the moving inner gear frame. This allows the detection block to drive the two temperature sensors to move back and forth inside the hair straightener under test, thereby increasing the detection range of the heating plates on both sides of the hair straightener under test and effectively improving the accuracy of the detection results.

[0017] 2. By controlling the downward movement of the positioning plate through the electric push rod, the hair straightener to be tested can be pressed and fixed on the right-angle C-shaped frame, thereby ensuring the stability of the hair straightener to be tested during testing;

[0018] In summary, this invention, by controlling the incomplete gear and the intermittent staggered meshing of the racks on both sides of the moving internal gear frame with the drive motor, enables the detection block to drive two temperature sensors to reciprocate within the hair straightener under test, thereby increasing the detection range of the heating plates on both sides of the hair straightener under test and effectively improving the accuracy of the hair straightener test results.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1 to 3 An automatic detection device for hair straighteners, comprising:

[0025] The right-angled C-shaped frame 1 and the hair straightener 2 to be tested placed on the right-angled C-shaped frame 1 are provided. An electric push rod 15 is fixedly installed on the inner top of the right-angled C-shaped frame 1. The drive end of the electric push rod 15 is vertically downward and a positioning plate 16 is fixedly installed thereon. By pushing the positioning plate 16 downward by the electric push rod 15, the hair straightener 2 to be tested can be pressed and fixed on the right-angled C-shaped frame 1, thereby ensuring the stability of the hair straightener 2 to be tested during testing.

[0026] The control display 3 is fixedly installed on the front side of the right-angled C-shaped frame bracket 1; the detection block 10 is movably set inside the hair straightener 2 to be tested. Temperature sensors 11 are fixedly installed on both the front and rear sides of the detection block 10, and the temperature sensors 11 are electrically connected to the control display 3. The two temperature sensors 11 can simultaneously detect the temperature of the heating plates on both sides of the hair straightener 2 to be tested, and the detection results can also be displayed on the control display 3. This part is the existing public technology of those skilled in the art, and this technical solution will not be described in detail.

[0027] The reciprocating assembly includes a through hole 4 on the top of a right-angled C-shaped frame 1. Support rods 5 slide through both sides of the through hole 4. The opposite ends of the two support rods 5 are fixedly connected to a movable inner toothed frame 6. The longitudinal section of each support rod 5 is rectangular, which ensures that the movable inner toothed frame 6 will not deflect when it moves.

[0028] The movable internal gear frame 6 is equipped with an incomplete gear 7. The inner top and inner bottom of the movable internal gear frame 6 are fixedly installed with racks, and the racks mesh with or separate from the incomplete gear 7. The front side of the right-angled C-shaped frame fixing bracket 1 is fixedly installed with a drive motor 8 for driving the incomplete gear 7 to rotate. The bottom of the movable internal gear frame 6 is fixedly installed with a connecting rod 9, and the connecting rod 9 is detachably connected to the detection block 10.

[0029] Furthermore, a stud 12 is fixedly installed on the top of the detection block 10, and a threaded groove 13 is opened at the bottom of the connecting rod 9. The threaded groove 13 is threadedly connected to the stud 12. A conductive sheet 14 is fixedly installed on the top of the threaded groove 13 and the top of the stud 12. By rotating the detection block 10, the two temperature sensors 11 can be disassembled and replaced for maintenance. At the same time, after the stud 12 is screwed into the threaded groove 13, the two temperature sensors 11 can be energized by the contact between the two conductive sheets 14.

[0030] The working principle of this utility model is as follows:

[0031] When using, first place the hair straightener 2 to be tested on the right-angle C-shaped frame fixing bracket 1, then start the electric push rod 15 to push the positioning plate 16 down, and press and fix the hair straightener 2 to be tested on the right-angle C-shaped frame fixing bracket 1;

[0032] At this time, the two temperature sensors 11 can simultaneously detect the temperature of the heating plates on both sides of the hair straightener 2 under test, and then display the detection results on the control display 3, thus completing the detection of whether the temperature of the heating plates on both sides of the hair straightener 2 under test is consistent.

[0033] At the same time, the drive motor 8 is started to control the rotation of the incomplete gear 7. When the incomplete gear 7 meshes with the rack on one side of the moving inner gear frame 6, it can drive the moving inner gear frame 6 to move. Then, when the incomplete gear 7 does not mesh with the rack and meshes with the rack on the other side, it can drive the moving inner gear frame 6 to move in the opposite direction. Thus, under the continuous rotation of the incomplete gear 7, the moving inner gear frame 6 can be driven to move back and forth, which in turn allows the detection block 10 to drive the two temperature sensors 11 to move back and forth in the hair straightener 2 under test, thereby increasing the detection range of the heating plates on both sides of the hair straightener 2 under test and effectively improving the accuracy of the detection results.

[0034] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
