[0021] 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 protection scope of the present utility model. Example 1

[0022] As attached Figures 1 to 4 The device shown is a coupling control device for an air source and a gas-fired water heater unit. It includes a housing 1 made of metal, which serves as a support and protection. Both sides of the housing 1 are provided with arc-shaped plates 2 made of stainless steel, which have good corrosion resistance and stability when in contact with heated materials, ensuring structural stability. The arc-shaped plates 2 are connected to each other so that the heat pump port 6 and the gas heating port 7 can converge in the conical structure formed by the arc-shaped plates 2 and be discharged into the connection port 3, ensuring the uniformity of the materials. The connection port 3 is provided on one side of the arc-shaped plate 2 for connecting to the indoor unit, which is convenient for operators.

[0023] The other side of the arc-shaped plate 2 is provided with a rack 4 made of high-hardness metal material, which is used in cooperation with a gear 11 to realize the up-down displacement of the sealing mechanism 5. The rotation of the gear 11 drives the bracket 10 fixed on the rack 4 to move up and down, so that the sealing layer 14 can seal the heat pump port 6 or the gas heating port 7 alone. The rack 4 is provided with four groups, which are evenly arranged along the horizontal direction of the shell 1. The four groups of racks 4 enable the sealing mechanism 5 to keep stable up-down displacement, ensuring the stability of the device during operation. The outer wall of the rack 4 is provided with a sealing mechanism 5. In the sealing mechanism 5, four groups of gears 11 are arranged on both sides of the bracket 10. These gears 11 are evenly arranged along the circumferential direction of the outer wall of the bracket 10. The gears 11 are engaged with the rack 4 fixed on the shell 1. The bracket 10 is internally provided with a micro motor 12. The micro motor 12 is connected to an extension rod 13 on one side. After receiving the instruction of the control mainboard 8, the micro motor 12 will start to control the extension rod 13 to drive the sealing layer 14 to seal the port. This design enables the sealing mechanism 5 to selectively seal the heat pump port 6 or the gas heating port 7 or work simultaneously according to the actual heating demand.

[0024] The sealing mechanism 5 is provided with a heat pump port 6 on one side. The heat pump port 6 is provided with a gas heating port 7 on one side. The heat pump port 6 and the gas heating port 7 are made of stainless steel material, which has good corrosion resistance and heat conductivity. The heat pump port 6 and the gas heating port 7 should be installed in the predetermined position, usually directly connected with the air source heat pump 15 and the gas water heater 16. After installation, pressure test and leakage test are carried out to ensure that the sealing performance and pressure resistance of the two groups of ports meet the standard. The sealing mechanism 5 is provided with a control mainboard 8 on one side. The control mainboard 8 is provided with a temperature sensor 9 on one side. The model of the temperature sensor 9 is DS18B20. Through the monitoring and analysis of outdoor temperature, the sealing mechanism 5 is controlled to enable the gas heating port 7 to assist in heating output, so as to ensure that the indoor temperature set by the user remains within a comfortable range. The temperature sensor 9 monitors the indoor and outdoor temperatures in real time and transmits the data to the control mainboard 8. Through intelligent control, the working mode of the air source heat pump 15 and the gas water heater 16 is automatically switched according to the outdoor temperature and the heating demand, realizing efficient and energy-saving heating. Example 2

[0025] Based on the embodiment 1, the scheme in embodiment 1 is further refined in combination with the specific working mode as shown in the following: Figures 1 to 4 The details are described below:

[0027] As a preferred implementation, the heat pump port 6 is provided with an air source heat pump 15 on one side, and the gas heating port 7 is provided with a gas water heater 16 on one side, further, the air source heat pump 15 utilizes the heat in the air to achieve heating through compression of refrigerant circulation, which is high in efficiency and environmentally friendly. However, affected by outdoor temperature, the efficiency decreases in low temperature environment. The gas water heater 16 heats by burning natural gas, which is stable in efficiency and not affected by outdoor temperature. However, it has high energy consumption cost and produces pollutants.

[0028] As a preferred implementation, the air source heat pump 15 comprises a condenser 17, an expansion valve 18, an evaporator 19 and a compressor 20, one side of the condenser 17 is connected with the heat pump port 6, the other side of the condenser 17 is provided with the expansion valve 18, one side of the expansion valve 18 is provided with the evaporator 19, one side of the evaporator 19 is provided with the compressor 20, further, the condenser 17 is provided with refrigerant and a passage, the expansion valve 18 is installed at the outlet of the condenser 17, the flow and pressure of the refrigerant are controlled by adjusting the valve opening, the evaporator 19 is located downstream of the expansion valve 18, the refrigerant is evaporated and absorbs heat at this point, and the compressor 20 is connected after the evaporator 19, compresses the evaporated refrigerant into high-temperature and high-pressure gas, and then the high-temperature and high-pressure gas enters the connecting port 3 through the heat pump port 6 connected with the passage of the condenser 17.

[0029] As a preferred embodiment, the heat pump port 6 and the gas heating port 7 are located on the same section of the shell 1, and the sealing mechanism 5 is displaced up and down along the rack 4 under the instruction of the control mainboard 8, so that the sealing layer 14 seals the heat pump port 6 or the gas heating port 7 alone, while there is a gap between the heat pump port 6 and the gas heating port 7, and the sealing mechanism 5 can stop in the gap through the rack 4. Further, when it is necessary to use the air source heat pump 15 or the gas water heater 16 alone, the control mainboard 8 sends an instruction to make the sealing layer 14 move to the corresponding position to seal the heat pump port 6 or the gas heating port 7 alone. According to the data of the temperature sensor 11, the system can automatically determine and switch the heating mode, and select the most energy-saving and efficient heating mode. In a low-temperature environment, the air source heat pump 15 is used preferentially; in a high-temperature environment or when a larger heating capacity is needed, the gas water heater 16 is started to assist heating, thereby reducing unnecessary energy consumption and improving the energy efficiency ratio of the overall system.

[0030] As a preferred embodiment, when the sealing layer 14 seals the heat pump port 6 or the gas heating port 7 alone, the telescopic rod 13 is compressed under the push of the micro motor 12 after the accurate alignment of the sealing layer 14. Further, by applying additional force through the telescopic rod 13, the contact pressure between the sealing layer 14 and the port can be increased, thereby improving the sealing effect and reducing heat loss. Under different temperature conditions, the thermal expansion and contraction of materials may cause the sealing performance to decrease, and the telescopic rod 13 can compensate for these changes by adjusting the applied force to ensure continuous good sealing.
