Description

Technical Field

[0001] This utility model relates to the field of headrest technology, and in particular to a headrest testing device. Background Technology

[0002] Car headrests are an important component of vehicle seats, combining driving comfort features with safety protection functions. They are mainly used to relieve neck fatigue and provide collision buffer protection. Their core structure includes a support body and cushioning materials. Before the headrests leave the factory, the volatile odor inside the headrests needs to be tested.

[0003] A search revealed a Chinese patent (application number "202322869965.1") that discloses "a device for detecting the odor volatilization of car seat headrests." This device includes a sealed box structure with a lifting structure fixedly installed on the bottom surface of the sealed box structure. A detection device is fixedly installed on one side surface of the sealed box structure. An air-suction sealing cover is fixedly connected to one end surface of the lifting structure, and a connecting line is fixedly connected to the surface of the air-suction sealing cover. A conveying cover structure is fixedly connected to one end surface of the connecting line. However, during use, the device does not heat the inside of the sealed box, resulting in a slow odor volatilization rate from the headrest, slow detection speed, and low practicality. Utility Model Content

[0004] This utility model provides a headrest detection device, which solves the problem that the detection device proposed in the prior art does not heat the inside of the sealed box when detecting headrest odor, resulting in a slow odor evaporation rate, slow detection speed, and low practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A headrestling testing device includes a testing box and a gas sensor. The testing box includes an insulated box, two "L"-shaped mounting blocks with several mounting holes on one side of their outer walls, and several PTC heaters respectively embedded in the mounting holes. The top of the testing box is provided with two heat exchange mechanisms. Each heat exchange mechanism includes an insulation box bolted to the top outer wall of the insulated box, an insulation plate fixed to the middle inner wall of the insulation box, several heat pipes descending in a stepped manner at their lower parts, and a fan bolted to one side of the outer wall of the insulation box. A purification assembly is provided between the two insulation boxes. The purification assembly includes a mounting box bolted to the top outer wall of the insulated box and a plate-type activated carbon filter slidably fitted inside the mounting box.

[0006] Preferably, the two mounting blocks are respectively fixed on the inner wall of the insulation box, a sealing frame is fixed on the inner wall of the insulation box, and the sealing frame is respectively fixed on the outer wall of the two mounting blocks, and the gas sensor penetrates and is fixed on the inner wall of the top of the insulation box.

[0007] The above method uses multiple PTC heaters to generate heat, which heats the headrest inside the insulated box, accelerating the evaporation of any volatile odors that may be present in the headrest. Subsequently, gas sensors analyze the composition and concentration of the gas inside the insulated box and display the information on a computer or screen.

[0008] Preferably, one of the mounting blocks has a door hinged to one outer wall, and a handle is bolted to one outer wall of the door.

[0009] Preferably, a connecting pipe is fixed on one inner wall of the heat insulation box, and the bottom end of the connecting pipe is fixed on the top inner wall of the heat insulation box. A solenoid valve is installed at one end of the connecting pipe. Several heat pipes pass through and are fixed on the outer wall of the heat insulation board. A cover plate is bolted to the top outer wall of the heat insulation box.

[0010] Preferably, each of the two heat insulation boxes has an air guide hood bolted to one side of its outer wall, and each of the two air guide hoods has a conveying pipe fixed to one side of its inner wall. One end of each conveying pipe is fixed to the lower inner wall of one side of the heat insulation box, and a check valve is provided on the outer wall of one end of each conveying pipe.

[0011] Preferably, an exhaust plate is bolted to the top outer wall of the installation box, and connecting rods are fixed to the four corners of the bottom outer wall of the exhaust plate. The plate-type activated carbon filter is bolted to the bottom outer wall of the four connecting rods. Two connecting pipes are fixed to the lower outer wall of one side of the installation box, and one end of the two connecting pipes is fixed to the lower inner wall of one side of the two heat insulation boxes.

[0012] The above scheme involves opening a solenoid valve to allow hot air from the insulation box to enter the heat insulation chamber. The hot air exchanges heat with the lower part of multiple heat pipes, and then the heat pipes transfer heat to the upper part. A fan delivers outside air into the heat insulation chamber to cool the upper part of the heat pipes. The hot air is then delivered back into the insulation chamber, and the cooled odorous gas enters the installation chamber. A plate-type activated carbon filter purifies the odorous gas. This process is repeated multiple times to ensure that the odorous gas in the insulation chamber is completely purified.

[0013] The beneficial effects of this utility model are as follows: Multiple PTC heaters generate heat to heat the headrest inside the insulation box, accelerating the evaporation of any volatile odors that may be present inside. Subsequently, gas sensors analyze the composition and concentration of the gas inside the insulation box and display the information on a computer or screen. The ability to heat the inside of the insulation box during detection accelerates the evaporation of volatile odors inside the headrest, improving detection speed and practicality.

A solenoid valve is installed at one end of the connecting pipe 402. Several heat pipes 404 pass through and are fixed to the outer wall of the insulated plate 403. A cover plate 405 is bolted to the top outer wall of the insulated box 401. Air guide hoods 5 are bolted to one side outer wall of each of the two insulated boxes 401, and air guide hoods 5 are fixed to one side inner wall of each of the two air guide hoods 5. The system includes two conveying pipes 6, one end of which is fixed to the lower inner wall of one side of the insulation box 101. Each of the two conveying pipes 6 has a check valve on the outer wall of one side. A purification assembly 7 is provided between the two insulation boxes 401. The purification assembly 7 includes a mounting box 701 bolted to the top outer wall of the insulation box 101 and a plate activated carbon filter 704 slidably fitted inside the mounting box 701.
