Example

[0034] See also Figure 1-7 The present invention provides a technical solution: a hot and cold stimulator, including a hot and cold air supply device 100 and a hot and cold pipe air outlet mechanism 200.

[0035] The hot and cold air outlet mechanism 200 is connected and fixed to the output end of the hot and cold air supply device 100, and is used to achieve alternating hot and cold outputs to improve the stimulation effect on the skin.

[0036] See also Figure 1 , Figure 2 and Figure 4 The hot and cold air supply device 100 includes a base plate 110, a hot air blower 120 and a cold air blower 130, and the hot air blower 120 and the cold air blower 130 are both fixed on the top surface of the base plate 110; a support leg 111 is fixed to the bottom of the base plate 110, and the support leg 111 is symmetrically fixed at the four corners of the base plate 110, and the setting of the support leg 111 can facilitate the support and placement of the hot and cold stimulator; the output end of the hot air blower 120 is fixedly connected to the hot air duct 210 through a first connecting pipe 121, and the output end of the cold air blower 130 is fixedly connected to the cold air duct 220 through a second connecting pipe 131. Through the setting of the first connecting pipe 121 and the second connecting pipe 131, the hot air and cold air can be conveniently transported. The hot air blower 120 and the cold air blower 130 here are equipped with adjustment switches that can adjust the output power.

[0037] A protective shell 140 is installed on the top surface of the base plate 110, and the hot air blower 120 and the cold air blower 130 are located inside the protective shell 140; the protective shell 140 includes a shell 141, connecting ears 142 and fixing parts 143, the connecting ears 142 are fixed to the outer surfaces of both sides of the shell 141, the fixing parts 143 pass through the connecting ears 142 and extend to the outside, and the fixing parts 143 are screwed to the inside of the base plate 110, where the fixing parts 143 are bolts. Through the arrangement of the shell 141, the connecting ears 142 and the fixing parts 143, the hot air blower 120 and the cold air blower 130 can be conveniently protected to reduce the damage they suffer.

[0038] See also Figure 1-Figure 3and Figure 5-Figure 7 The hot and cold pipe air outlet mechanism 200 includes a hot air pipe 210, a cold air pipe 220, a hollow pipe 240, an elastic sealing component 250 and an air outlet pipe 260. The hot air pipe 210 is connected to the hot air blower 120, and the cold air pipe 220 is connected to the cold air blower 130. The air outlet pipe 260 is connected and fixed to the ends of the hot air pipe 210 and the cold air pipe 220. Two hollow pipes 240 are provided. The two hollow pipes 240 are respectively slidably connected to the inside of the hot air pipe 210 and the cold air pipe 220. Here, the hollow pipe The end cross-section of 240 is set to be semicircular. This setting can reduce the contact area between the corner of the baffle 262 and the end of the hollow tube 240, thereby facilitating the expansion and contraction of the hollow tube 240 under the elastic action of the elastic member 252. The elastic sealing assembly 250 is fixed between the hollow tube 240 and the air outlet pipe 260. A motor 261 is fixed to the bottom of the air outlet pipe 260. A baffle 262 is fixed to the output end of the motor 261. The baffle 262 is slidably connected to the top surface of the hollow tube 240.

[0039] A connecting plate 230 is fixed between the hot air duct 210 and the cold air duct 220, and three connecting plates 230 are arranged at equal distances. The arrangement of the connecting plate 230 can make the hot air duct 210 and the cold air duct 220 more firmly connected; a slide groove 211 is provided on the inner surface of the hot air duct 210, and a limiting slider 241 matching the slide groove 211 is fixed on the outer surface of the hollow tube 240. The limiting slider 241 is slidably connected to the inside of the slide groove 211. Through the arrangement of the slide groove 211 and the limiting slider 241, the hollow tube 240 can be made more stable during the process of telescopic movement back and forth.

[0040] The elastic sealing assembly 250 includes an annular plate 251, an elastic member 252 and a telescopic member 253. The annular plate 251 is fixed on the outer surface of the hollow tube 240, the elastic member 252 is fixed between the annular plate 251 and the air outlet pipe 260, the telescopic member 253 is fixed between the annular plate 251 and the air outlet pipe 260, and the telescopic member 253 is located on the outside of the elastic member 252. The elastic member 252 here is a spring, and the telescopic member 253 is a telescopic tube. The setting of the elastic member 252 here can facilitate the telescopic movement of the hollow tube 240. The setting of the telescopic member 253 can prevent air leakage at the position where the hollow tube 240 contacts the hot air pipe 210 and the cold air pipe 220, thereby reducing the stimulation effect.

[0041] A sealing layer 2621 is fixed to the surface of the baffle 262, and the sealing layer 2621 is tightly attached to the end of the hollow tube 240. The sealing layer 2621 here can be made of rubber material, which can enhance the sealing between the baffle 262 and the hollow tube 240 and improve the shielding effect; a holding portion 270 is fixed to the bottom of the hot air duct 210 and the cold air duct 220, and the holding portion 270 includes a horizontal plate 271 and a handle 272. The horizontal plate 271 is fixed to the bottom of the hot air duct 210 and the cold air duct 220, and the handle 272 is fixed to the bottom of the horizontal plate 271. Here, through the arrangement of the horizontal plate 271 and the handle 272, the hot air duct 210 and the cold air duct 220 can be held, so that it is convenient to use.

[0042] Specifically, the working principle of the hot and cold stimulator is as follows: when in use, the nozzle of the air outlet pipe 260 is aimed at the skin, and then the hot air blower 120 and the cold air blower 130 work at the same time, so that the hot air and the cold air are transported to the hot air pipe 210 and the cold air pipe 220 through the first connecting pipe 121 and the second connecting pipe 131. At the same time, the motor 261 works to drive the baffle 262 to rotate. During the rotation process, the baffle 262 can make the hollow tube 240 always close to the surface of the baffle 262 under the action of the elastic member 252. Then, when one of the hollow tubes 240 in the hot air pipe 210 and the cold air pipe 220 leaks out of the air outlet, the baffle 262 will complete the covering of the other hollow tube 240. Then, the hot and cold air flows will be alternately output from the air outlet of the air outlet pipe 260 to act on the skin. In this way, when the hot and cold stimulator is used, the skin can be continuously subjected to hot and cold stimulation, thereby improving the continuity of the hot and cold stimulation, enhancing the stimulation effect, and being more convenient to use.

[0043] It should be noted that the specific models and specifications of the hot air blower 120, the cold air blower 130 and the motor 261 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0044] The power supply and principle of the hot air blower 120, the cold air blower 130 and the motor 261 are clear to those skilled in the art and will not be described in detail here.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
