[0002] Currently, a method of calculating air conditioning costs by area or terminal electricity consumption is often used in air-conditioning systems. This method cannot truly reflect the difference in energy consumption caused by different set temperatures and different actual indoor temperatures. Therefore, it cannot be recognized by users and may even cause some users to maliciously lower the set temperature, resulting in energy waste. The inability to accurately calculate terminal energy consumption is an important reason for calculating air conditioning costs by area or terminal electricity consumption. It is also the key reason why air-conditioning systems cannot accurately achieve energy-saving control. To solve this problem, an air-conditioning terminal energy consumption metering device is disclosed.

[0003] In the process of realizing the utility model, the inventor found that there are at least the following problems in the prior art that have not been solved: during use, the traditional air-conditioning terminal energy consumption metering equipment cannot automatically clean the temperature and humidity sensor detection end, the temperature and humidity sensor detection end is easily inaccurate due to the adhesion of dirt in the air inlet and outlet ducts for a long time, and the traditional cleaning mechanism has poor stability when cleaning the temperature and humidity sensor detection end. Therefore, it is necessary to design a new technical solution to solve it. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet actual needs, and provide an air-conditioning terminal energy consumption metering device to solve the technical problems that the temperature and humidity sensor detection end on the current air-conditioning terminal energy consumption metering device is easily prone to inaccurate detection data due to dirt adhesion in the air inlet and outlet ducts for a long time and the cleaning mechanism has poor stability when cleaning the temperature and humidity sensor detection end.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: to design an air-conditioning terminal energy consumption metering device, including an air inlet pipe and an air outlet pipe, the air inlet pipe and the air outlet pipe are of the same model, and the inner walls of the air inlet pipe and the air outlet pipe are connected with mounting bearings through electric push rods, and a rotating shaft is arranged on the mounting bearing, and blades are installed around the outside of the rotating shaft, and two rotating grooves are opened at the other end of the rotating shaft, and the two rotating grooves are connected to two support plates through two fixed shafts, and the other ends of the two support plates are respectively installed with a first cleaning brush head and a second cleaning brush head, and a spring member is also connected between the two support plates through a mounting head.

[0006] Preferably, the mounting end of the electric push rod is fixedly connected to the inner walls of the air inlet and outlet pipes, the output end of the electric push rod is fixedly connected to the outer ring of the mounting bearing, and the inner ring of the mounting bearing is fixedly connected to one end of the rotating shaft.

[0007] Preferably, the rotating groove is symmetrically opened on both sides of the other end of the rotating shaft, both ends of the fixed shaft are fixedly connected to the inner wall of the rotating groove, and one end of the support plate is sleeved on the outside of the fixed shaft and movably connected to the inner wall of the rotating groove.

[0008] Preferably, one end of the mounting head is fixedly connected to the outer surface of the support plate, and both ends of the spring member are fixedly connected to the other ends of the two mounting heads.

[0009] Preferably, a temperature and humidity sensor is sandwiched between the first cleaning brush head and the second cleaning brush head, and the detection positions of the two temperature and humidity sensors are both located on the inner walls of the air inlet pipe and the air outlet pipe, and correspond to the positions of the mounting bearings.

[0010] Preferably, the temperature and humidity sensor is connected to a meter via a conductive wire, a plurality of wire connectors are installed at the bottom end of the meter, one of the wire connectors is also connected to a flow meter via a conductive wire, and the flow meter is installed on the air inlet pipe.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model is provided by installing a bearing, a rotating shaft, blades, a rotating groove, a fixed shaft, a support plate, a first cleaning brush head and a second cleaning brush head. When wind flows inside the air inlet pipe and the air outlet pipe, the wind drives the rotating shaft to rotate on the installed bearing through the blades, and then the rotating shaft drives the support plate together with the first cleaning brush head and the second cleaning brush head to rotate, so that the temperature and humidity sensor detection end on the energy consumption metering device is automatically cleaned, and the phenomenon of inaccurate detection data caused by dirt adhesion of the temperature and humidity sensor detection end in the air inlet pipe and the air outlet pipe for a long time is avoided;

[0013] By allowing the support plate to rotate in the rotation groove and using the spring member, the minimum spacing between the two support plates can be limited, thereby avoiding the phenomenon that the support plate cannot rotate due to the small spacing between the two support plates and the excessive clamping force of the first cleaning brush head and the second cleaning brush head on the detection end of the temperature and humidity sensor, thereby improving the stability of the detection end of the temperature and humidity sensor during cleaning;

[0014] When the detection end of the temperature and humidity sensor does not need to be cleaned, the electric push rod drives the rotating shaft to move downward through the installed bearing, so that the first cleaning brush head and the second cleaning brush head on the rotating shaft are separated from the detection end of the temperature and humidity sensor, thereby avoiding the first cleaning brush head and the second cleaning brush head being in a rotating state all the time and causing wear on the temperature and humidity sensor, thereby reducing the accuracy of the temperature and humidity sensor.

[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0024] Example 1: An air conditioner terminal energy consumption metering device, see Figures 1 to 4 , including an air inlet pipe 1 and an air outlet pipe 11, the air inlet pipe 1 and the air outlet pipe 11 are of the same model, and the inner walls thereof are connected with mounting bearings 12 through electric push rods 4, and the mounting bearings 12 are provided with rotating shafts 13, and the mounting ends of the electric push rods 4 are fixedly connected to the inner walls of the air inlet pipe 1 and the air outlet pipe 11, and the output ends of the electric push rods 4 are fixedly connected to the outer rings of the mounting bearings 12. When the detection end of the temperature and humidity sensor does not need to be cleaned, the electric push rod drives the rotating shaft to move downward through the mounting bearings, so that the first cleaning brush head and the second cleaning brush head on the rotating shaft are separated from the detection end of the temperature and humidity sensor, thereby avoiding the first cleaning brush head and the second cleaning brush head being in a rotating state all the time, causing the temperature and humidity sensor to wear, thereby reducing the accuracy of the temperature and humidity sensor;

[0025] The inner ring of the mounting bearing 12 is fixedly connected to one end of the rotating shaft 13, and blades 14 are installed around the outside of the rotating shaft 13. The other end of the rotating shaft 13 is provided with two rotating grooves 15, and the two rotating grooves 15 are connected to two supporting plates 17 through two fixed shafts 16. The rotating grooves 15 are symmetrically provided on both sides of the other end of the rotating shaft 13, and the two ends of the fixed shaft 16 are fixedly connected to the inner wall of the rotating groove 15. One end of the supporting plate 17 is sleeved on the outside of the fixed shaft 16 and is movably connected to the inner wall of the rotating groove 15. The other ends of the two supporting plates 17 are respectively provided with first cleaning The grooming brush head 18 and the second cleaning brush head 19, when wind flows inside the air inlet pipe 1 and the air outlet pipe 11, the wind will drive the rotating shaft 13 to rotate on the mounting bearing 12 through the blades 14, and then the rotating shaft 13 drives the support plate 17 together with the first cleaning brush head 18 and the second cleaning brush head 19 to rotate, so as to realize automatic cleaning of the detection end of the temperature and humidity sensor 3 on the energy consumption metering device, avoiding the phenomenon that the detection end of the temperature and humidity sensor 3 is inaccurate due to the adhesion of dirt in the air inlet pipe 1 and the air outlet pipe 11 for a long time;

[0026] A spring member 21 is also connected between the two support plates 17 via the mounting head 2, one end of the mounting head 2 is fixedly connected to the outer surface of the support plate 17, and both ends of the spring member 21 are fixedly connected to the other ends of the two mounting heads 2. By allowing the support plate 17 to rotate in the rotating groove 15 and cooperating with the use of the spring member 21, it is possible to limit the minimum spacing between the two support plates 17, thereby avoiding the phenomenon that the first cleaning brush head 18 and the second cleaning brush head 19 have too large a clamping force on the detection end of the temperature and humidity sensor 3 due to the small spacing between the two support plates 17, resulting in the support plate 17 being unable to rotate, thereby improving the stability of the detection end of the temperature and humidity sensor 3 during cleaning.

[0027] It is worth noting that see Figure 2 A temperature and humidity sensor 3 is clamped between the first cleaning brush head 18 and the second cleaning brush head 19. The detection parts of the two temperature and humidity sensors 3 are located on the inner walls of the air inlet pipe 1 and the air outlet pipe 11, and correspond to the positions of the mounting bearings 12, so that the temperature and humidity sensors 3 can detect the humidity and temperature inside the air inlet pipe 1 and the air outlet pipe 11 at the end of the air conditioner.

[0028] It is worth mentioning that see Figure 1 The temperature and humidity sensor 3 is connected to a meter 31 through a conductive wire. A plurality of wire connectors 32 are installed at the bottom of the meter 31. One of the wire connectors 32 is also connected to a flow meter 33 through a conductive wire. The flow meter 33 is installed on the air inlet pipe 1, so that the meter 31 can calculate and display the data detected by the temperature and humidity sensor 3 and the flow meter 33.
