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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0025] This application discloses a side-temperature controlled heating tube assembly with a larger creepage distance. (Refer to...) Figure 1A side-temperature controlled heating tube assembly with a larger creepage distance includes a heating tube body 1, a wire 2 electrically connected to the bottom end of the heating tube body 1, a temperature controller 3 fixedly connected to the left end face of the heating tube body 1, a cooling component 4 disposed on the surface of the temperature controller 3, and a collection component 5 disposed on the surface of the cooling component 4.

[0026] Reference Figures 2-4 The cooling component 4 includes a heat-conducting plate 41 fixedly connected to the surface of the thermostat 3. A fan 42 is fixedly connected to the surface of the thermostat 3. The heat-conducting plate 41 and the thermostat 3 are adapted and fitted together. The heat-conducting plate 41 is located between the thermostat 3 and the fan 42. The heat-conducting plate 41 can absorb the heat from the surface of the thermostat 3, while the cold air blown out by the fan 42 will stabilize the heat-conducting plate 41, thereby achieving the purpose of cooling the thermostat 3 and preventing the fan 42 from blowing directly onto the thermostat 3, thus preventing dust from being blown directly onto the surface of the thermostat 3, thereby improving the service life of the thermostat 3. A dustproof net 43 is fixedly connected to one end of the fan 42 near the heat-conducting plate 41, and a dustproof net 43 is fixedly connected to the side of the heat-conducting plate 41. An annular plate 44 is connected to the thermostat 3. An annular groove 45 is formed on the inner wall of the annular plate 44 near the heat-conducting plate 41. A connecting pipe 46 is fixedly connected to the surface of the annular plate 44 away from the heat-conducting plate 41. A hollow annular pipe 47 is provided on the side of the thermostat 3. An air outlet 48 is formed on the side of the hollow annular pipe 47 near the side of the thermostat 3. The connecting pipe 46 is connected to the annular groove 45 and the interior of the hollow annular pipe 47 respectively. The air outlet 48 faces the side of the thermostat 3. The air duct formed by the annular plate 44, the connecting pipe 46 and the hollow annular pipe 47 will guide the air blown on the heat-conducting plate 41 to the side of the thermostat 3, thereby achieving the purpose of cooling the thermostat 3 from the side and improving the heat dissipation efficiency.

[0027] Reference Figures 4-6 The collecting component 5 includes a baffle 51 that is snapped into the inside of the connecting pipe 46 near the annular plate 44. A groove 52 is formed at one end of the baffle 51 near the outside of the connecting pipe 46. A pressure spring 53 is fixedly connected to the inner wall of the groove 52. An abutment plate 54 is fixedly connected to the other end of the pressure spring 53. A groove is formed on the surface of the connecting pipe 46. The baffle 51 passes through the groove and is snapped into the inside of the connecting pipe 46. The end of the baffle 51 near the inside of the connecting pipe 46 is adapted to fit against the inner wall of the connecting pipe 46, abutting against... Under the action of the pressure spring 53, the connecting plate 54 confines the baffle 51 inside the connecting pipe 46. A dustproof opening 55 is provided on the surface of the baffle 51 near the inside of the connecting pipe 46. A collecting plate 56 is fixedly connected to one end of the baffle 51 near the inside of the connecting pipe 46. The end of the abutting plate 54 away from the pressure spring 53 is adapted to contact the inner wall of the groove opened in the connecting pipe 46. The collecting plate 56 is attached to the inner wall of the connecting pipe 46 and can collect the dust blown towards the dustproof opening 55.

[0028] Working principle: After the operator installs the thermostat 3 on the left side wall of the heating tube body 1, the fan 42 is driven to run after the thermostat 3 is turned on. At this time, the fan 42 drives the airflow to blow on the heat conduction plate 41. Since the heat conduction plate 41 and the thermostat 3 are in contact, the heat on the surface of the thermostat 3 will be transferred to the surface of the heat conduction plate 41. The fan 42 then cools the heat conduction plate 41 and the thermostat 3 by blowing the airflow on the heat conduction plate 41.

[0029] In addition, the airflow blowing through the heat-conducting fins 41 will enter the interior of the connecting pipe 46 through the annular groove 45, and then be blown into the interior of the hollow annular pipe 47 through the connecting pipe 46. After that, it will be blown towards the side of the thermostat 3 through the air outlet 48 opened through the hollow annular pipe 47, thereby accelerating the cooling efficiency of the thermostat 3.

[0030] The airflow blowing into the connecting pipe 46 first passes through the dustproof port 55 opened by the baffle 51. At this time, due to the elasticity of the pressure spring 53, the abutment plate 54 is tightly pressed against the groove of the connecting pipe 46. Therefore, the baffle 51 is always stably located inside the connecting pipe 46, and the dustproof port 55 will block the dust moving with the airflow on the surface of the baffle 51. Then the dust will gradually accumulate inside the collecting plate 56. When cleaning is required, the abutment plate 54 can be pushed to compress the pressure spring 53. At this time, the baffle 51 can be directly removed from the inside of the connecting pipe 46. After cleaning, it can be reinstalled.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
