[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0026] See also Figure 1 - Figure 5 A constant temperature heating device and a tea frying machine include a constant temperature water tank 1, a hemispherical chute 101 is provided on the top of the constant temperature water tank 1, a plurality of pressure relief ports 102 are opened through the top of the constant temperature water tank 1, a plurality of supporting legs 2 are fixedly connected to the bottom of the constant temperature water tank 1, a water inlet pipe 3 is connected to one side of the constant temperature water tank 1, a drain pipe 4 is connected to the bottom of the constant temperature water tank 1, the number of the plurality of supporting legs 2 is four, and the four supporting legs 2 are respectively located at the four corners of the bottom of the constant temperature water tank 1.
[0027] like Figure 1 - Figure 5As shown, a constant temperature heating device and a tea frying machine in the utility model are similar in structure to the existing constant temperature heating device and tea frying machine, such as a constant temperature ball pot tea frying machine disclosed in the patent with publication number CN203913243U. The main improvement of the utility model is that the constant temperature water tank 1 can be filled with hot water, further improving the heating effect of the tea frying machine, so that the tea frying machine is heated more evenly, such as Figures 1 to 5 As shown, when the constant temperature heating device and the tea frying machine in the utility model are in use, after hot water is injected into the constant temperature water tank 1 through the water inlet pipe 3, the hot water will inevitably produce a certain amount of steam, which naturally rises to the top space of the constant temperature water tank 1, and then is discharged from the constant temperature water tank 1 from the pressure relief port 102 at the top, and as the amount of water injected continues to increase, the gas is gradually squeezed upward from the pressure relief port 102 to the constant temperature water tank 1, thereby avoiding gas filling the constant temperature water tank 1, resulting in the inability to inject hot water into the gas space, affecting the overall heating of the constant temperature water tank 1, making the overall heating of the constant temperature water tank 1 more uniform, and improving the tea frying effect. At the same time, when the water temperature in the constant temperature water tank 1 gradually decreases and does not meet the needs of tea frying, it can be discharged from the constant temperature water tank 1 through the drain pipe 4 at the bottom. The drain pipe 4 is arranged at the bottom of the constant temperature water tank 1 to ensure that the water in the constant temperature water tank 1 can be completely discharged from the constant temperature water tank 1 as much as possible.
[0028] like Figure 1 - Figure 5 As shown, the number of the pressure relief ports 102 is four, and the four pressure relief ports 102 are respectively located at the four corners of the thermostatic water tank 1. The pressure relief ports 102 are arranged at the four vertices on the top of the thermostatic water tank 1, which can ensure that the steam, air, etc. in the thermostatic water tank 1 can be discharged smoothly, and avoid the existence of some gas in the thermostatic water tank 1.
[0029] like Figure 1 - Figure 5 As shown, a plurality of air relief valves 5 are fixedly connected to the top of the thermostatic water tank 1, and the plurality of air relief valves 5 are respectively connected to a plurality of pressure relief ports 102. After the thermostatic water tank 1 is filled with hot water, the air relief valves 5 can be closed to isolate the hot water in the thermostatic water tank 1 from the outside, thereby reducing the heat loss of the hot water in the thermostatic water tank 1.
[0030] like Figure 1 - Figure 5 As shown, there are two water inlet pipes 3, one for injecting hot water and the other for injecting cold water. The two water inlet pipes 3 are provided to facilitate injecting a certain proportion of cold water at the same time when injecting hot water into the thermostatic water tank 1, thereby preventing the hot water temperature from being too high and affecting the thermostatic effect.
[0031] like Figure 2As shown, the bottom of the thermostatic water tank 1 is designed to be funnel-shaped, and the drain pipe 4 is fixedly connected and communicated with the funnel-shaped bottom of the thermostatic water tank 1. The bottom of the thermostatic water tank 1 is set to be funnel-shaped, so that impurities, scale, etc. in the hot water injected into the thermostatic water tank 1 can fall into the funnel-shaped bottom below through precipitation, and then when the water is drained through the drain pipe 4, the impurities, scale, etc. are smoothly discharged from the thermostatic water tank 1, thereby improving the sewage discharge effect of the thermostatic water tank 1.
[0032] like Figure 1 - Figure 5 As shown, the outer walls of the water inlet pipe 3 and the drain pipe 4 are fixedly connected with a solenoid valve 6. The solenoid valves 6 are arranged on the water inlet pipe 3 and the drain pipe 4, and a plurality of solenoid valves 6 are connected to the control system to facilitate the control of the water inlet and outlet of the constant temperature water tank 1.
[0033] like Figure 1 - Figure 5 As shown, the outer wall of the thermostatic water tank 1 is fixedly connected with a thermal insulation layer 7. Adding the thermal insulation layer 7 to the outer wall of the thermostatic water tank 1 can reduce the heat loss of hot water in the thermostatic water tank 1 and improve the constant temperature effect. The thermal insulation layer 7 can be tin foil thermal insulation foam, etc., to provide a thermal insulation effect.
[0034] like Figure 1 - Figure 5 As shown, a reinforcement layer 8 is fixedly connected to the outer side of the insulation layer 7. Since most materials of the insulation layer 7 are relatively fragile and easily damaged, the reinforcement layer 8 is added to the outer side of the insulation layer 7 to protect the insulation layer 7, thereby reducing the probability of damage to the insulation layer 7. The reinforcement layer 8 can be made of relatively high-strength materials such as iron sheets and wooden boards.
[0035] like Figure 1 - Figure 5 As shown, the spherical pot body 9, the spherical pot cover 10 and the rotating handle 11 are also included. The spherical pot cover 10 is connected with the spherical pot body 9 by threads. The two sides of the spherical pot body 9 are fixedly connected with the rotating shaft 12. The rotating handle 11 is fixedly connected to one side of the rotating shaft 12 away from the spherical pot body 9. The tea frying machine is connected and fixed to each other by the spherical pot body 9 and the spherical pot cover 10, so as to be spliced into a whole spherical tea frying machine, and the spherical tea frying machine can match the hemispherical chute 101 on the thermostatic water tank 1, so as to transfer the heat of the hot water in the thermostatic water tank 1 into the spherical pot body 9, so as to heat the internal space of the spherical pot body 9 and complete the drying operation of the tea leaves in the spherical pot body 9. The rotating handle 11 can rotate the spherical pot body 9 through the rotating shaft 12, so that the overall surface of the spherical pot body 9 and the spherical pot cover 10 is more evenly in contact with the hemispherical chute 101, thereby improving the tea frying effect.
[0036] like Figure 1 - Figure 5As shown, two symmetrically arranged fixing rings 13 are fixedly connected to both sides of the top of the thermostatic water tank 1, the ball pot body 9 and the ball pot cover 10 are both slidably connected to the hemispherical chute 101, and the outer walls of the two rotating shafts 12 are respectively rotatably connected to the inner walls of the two fixing rings 13, and one end of the rotating shaft 12 away from the ball pot body 9 is fixedly connected to the rotating handle 11, and the rotating handle 11 is located outside the thermostatic water tank 1. The two fixing rings 13 are sleeved on the two rotating shafts 12, so that the ball pot body 9 and the ball pot cover 10 are fixed in the hemispherical chute 101 of the thermostatic water tank 1. When the rotating handle 11 is rotated, the rotating shaft 12 and the ball pot body 9 and the ball pot cover 10 are driven to rotate, and they are constrained by the fixing rings 13, so as to prevent the ball pot body 9 from rolling off the thermostatic water tank 1 due to rotation, thereby improving the stability of the tea frying operation.
[0037] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
