The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0031] like Figures 1 to 9As shown, a vortex thermostat of the utility model comprises a shell 1, a vortex conversion valve core 2, a vent connector 3 and an adjusting member 4; a first gas flow channel 11 and a second gas flow channel 12 are formed in the shell 1; the vortex conversion valve core 2 is arranged in the shell 1, the vortex conversion valve core 2 comprises a first channel 21, a second channel 22 and a side channel 23, the first channel 21 is connected to the first gas flow channel 11, the second channel 22 is connected to the second gas flow channel 12, one side of the side channel 23 is connected to the first channel 21, the vent connector 3 is arranged on the shell 1, and the vent connector 3 is connected to the other side of the side channel 23; the adjusting member 4 comprises an adjusting head 41 and an adjusting rod 42, the adjusting head 41 is movably arranged on the inner side of the first gas flow channel 11, the adjusting head 41 comprises a plurality of adjusting protrusions 411, a gap 412 is formed between two adjacent adjusting protrusions 411, an air channel for hot air flow to flow out is formed between the gap 412 and the inner wall of the first gas flow channel 11, and the adjusting rod 42 is fixed to the middle part of the adjusting head 41 to drive the cold air flow to flow back in the opposite direction.

[0032] In this way, the utility model involves a vortex thermostat, when in use, the compressed air is passed from the ventilation joint 3 into the vortex conversion valve core, the compressed air enters the first channel 21 through the side channel 23, and flows to the first gas flow channel 11 through the first channel 21. When flowing in the first gas flow channel 11, there is a pressure difference in the first gas flow channel 11, the pressure at the edge of the first gas flow channel 11 is high, and the pressure in the middle of the first gas flow channel 11 is low, so that the hotter gas moves to the edge of the first gas flow channel 11 to form a hot air flow, which is output through the air channel, while the cold gas moves to the middle of the first gas flow channel 11 to form a cold air flow, and the cold air flow flows in the opposite direction under the action of the adjusting rod 42, so that the cold air flow is output from the other end, and the hot air flow or the cold air flow can be selected to flow into the cabinet, thereby realizing the temperature control of the cabinet.

[0033] By setting the adjustment member 4, and the adjustment head 41 of the adjustment member 4 can be movably set inside the first gas flow channel 11, so as to control the stroke of the cold air flow, and the shell 1 can be provided with a semiconductor cooling plate and a cooling fan, so as to control the temperature of the air flow within a certain range.

[0034] Optionally, a mounting channel is formed in the first gas flow channel 11, a first connecting thread is formed on the inner side wall of the mounting channel, and a second connecting thread that matches the first connecting thread is formed on the outer side wall of the adjusting protrusion 411. By providing the mounting channel, it is convenient to install the adjusting member 4. During the specific installation, the adjusting member 4 is aligned with the mounting channel, and then the adjusting member 4 is rotated. Under the action of the first connecting thread and the second connecting thread, the adjusting member 4 moves forward or backward, thereby controlling the stroke of the cold air flow, and further controlling the temperature of the hot air flow and the cold air flow.

[0035] In this embodiment, the inner diameter of the second channel 22 gradually increases from close to the first channel 21 to away from the first channel 21, that is, the second channel 22 is trumpet-shaped. In this way, when the cold air flows, it has a Venturi effect, thereby forming a high-speed jet and accelerating the circulation cooling of the air.

[0036] Furthermore, a plurality of side channels 23 are provided, and the plurality of side channels 23 are evenly distributed on the vortex conversion valve core 2 . By providing a plurality of side channels 23 , it is convenient for the compressed gas in the vent connector 3 to pass into the first channel 21 from different side channels 23 .

[0037] Specifically, the side channels 23 are spirally distributed on the vortex conversion valve core 2, so that the airflow in the side channels 23 has a tendency to flow toward the first gas flow channel 11. Since the side channels 23 are spirally distributed on the vortex conversion valve core 2, when the compressed gas is introduced from different side channels 23, it is easy for the airflow to have a tendency to flow toward the first gas flow channel 11, thereby quickly dividing the compressed air into a hot airflow and a cold airflow. Among them, the principle of dividing the compressed air into a hot airflow and a cold airflow in the tube is the vortex tube principle, which is a prior art.

[0038] In this embodiment, a temperature sensor 5 is further included. The temperature sensor 5 is disposed on the housing 1 and is connected to the first gas flow channel 11. By disposing the temperature sensor 5, it is convenient to measure the temperature of the gas flow.

[0039] Furthermore, it also includes a connection joint 6 and a selection valve 7, one end of the connection joint 6 is connected to the first gas flow channel 11, and the selection valve 7 is connected to the other end of the connection joint 6. By providing the connection joint 6, it is convenient to connect the selection valve 7 to the shell 1, so as to control the output of the hot gas flow.

[0040] In some examples, the connecting joint 6 includes a first connecting part 61, a positioning part 62 and a second connecting part 63. The first connecting part 61 is connected to the first gas flow channel 11, the positioning part 62 is against the shell 1, and the second connecting part 63 is connected to the selection valve 7. A porous copper filter element 631 is arranged in the second connecting part 63. By setting the first connecting part 61, it is convenient to connect to the first gas flow channel 11. By setting the second connecting part 63, it is convenient to connect to the selection valve 7. By setting the porous copper filter element 631, the hot air flow is prevented from being directly ejected to cause greater damage, and it can play a filtering role to prevent larger impurities and particulate matter from entering.

[0041] Preferably, the adjusting member 4 is a temperature adjusting knob, which is provided with a positioning groove for driving the knob to rotate. Thus, a tool can be inserted into the positioning groove, and the tool can be rotated to rotate the temperature adjusting knob, thereby adjusting the position of the temperature adjusting knob.

[0042] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
