Referring now to fig. 1-8 in combination, in accordance with an embodiment of the present invention, a head assembly 200 is provided that includes a compressor head 2 and a temperature wire 1, the temperature wire 1 having opposite first and second ends 101, 102. The first end 101 of the temperature measuring wire 1 is located inside the compressor upper cover 2, and the first end 101 of the temperature measuring wire 1 is used for being connected with components inside the compressor housing 9 to sense the temperature of the components. The first end 101 of the temperature measuring wire 1 may be plugged into a component inside the compressor 100 through a terminal, or the first end 101 of the temperature measuring wire 1 may be wound around the component inside the compressor 100 through a winding manner.

The second end 102 of the temperature wire 1 has an extension 3, through which extension 3 the temperature wire 1 extends out of the compressor upper cover 2 to draw the temperature of said component out of the compressor upper cover 2.

In the above example, the temperature of the internal components of the compressor 100, such as the stator assembly 10, may be led out of the compressor 100 through the temperature measuring line 1 provided, and the internal components of the compressor 100 reflect the internal temperature of the compressor 100. The temperature measuring wire 1 can be connected with the temperature receiving device through the extending part 3, so that the internal temperature of the compressor 100 can be accurately fed back, abnormal abrasion of a motor and a pump body caused by overhigh temperature is avoided, and the reliability of the compressor 100 is effectively improved.

What needs to be explained here is: the specific structure of the temperature measuring line 1 is the prior art, and will not be described herein. In one specific example of an application, as shown in FIG. 1, the component internal to the compressor 100 described above may be a stator assembly 10. The compressor 100 is internally provided with a pump body assembly 7, the pump body assembly 7 comprises parts such as a crankshaft 8, a rotor assembly 13 is sleeved on the crankshaft 8, and the pump body is driven to operate by electrifying a motor, so that air suction, compression and air discharge of the lower compression mechanism are realized. The exhaust gas generated by the compression mechanism in the pump body assembly 7 flows upwards through the rotor assembly 13 and the stator assembly 10 to drive the motor to take away heat, so that the motor is guaranteed to normally operate (the exhaust gas flow path is shown in fig. 1), the exhaust gas flows through the motor and then is discharged out of the compressor 100 through the exhaust pipe 5, and the exhaust gas enters the air conditioner to circulate, so that the motor is used as a driving part to generate great heat in the whole operation process, and the position with high internal temperature of the compressor 100 is seen.

In the above example, by connecting the first end 101 of the temperature measuring wire 1 with the stator assembly 10 of the motor, the temperature of the high temperature position inside the compressor 100 can be directly obtained, and compared with the mode of arranging a temperature sensor on the air conditioner pipeline behind the exhaust pipe 5 of the compressor 100 in the prior art, the effect of accurate temperature measurement is realized; especially when refrigerant leaks or closes under the valve condition, the flow in the pipeline is few, can't take away the heat that compressor motor produced fast, and when the compressor intracavity temperature was accumulated, accurate acquisition motor temperature can avoid the motor to lead to demagnetization or the oil film of pump body subassembly part to be destroyed and influence the compressor life-span because of the high temperature.

The extending portion 3 extending out of the upper cover 2 of the compressor may be a wire connection member, or may be a wire core of the second end 102 of the temperature measuring wire 1, which may be specifically set according to actual needs. Several different embodiments of the extension 3 are described below.

As shown in fig. 1 and 3, the second end 102 of the temperature measuring wire 1 is provided with a wire member as the protruding portion 3. Wherein, through setting up the wiring spare as extension 3, the wiring between convenient temperature measurement line 1 and the temperature receiving arrangement.

In one example, as shown in fig. 1 and 2, the wiring element may be a wiring terminal 31. In another example, as shown in fig. 3 and 4, the wiring element may be a joint 32.

As shown in fig. 1, the compressor upper cover 2 may further be provided with a protective shell 6, where the protective shell 6 is used to cover the wiring member inside, so as to provide shell protection for the wiring member.

As shown in fig. 6 and 7, the foregoing protruding portion 3 may be a core of the second end 102 of the temperature measurement wire 1. In this example, since the temperature measuring wire 1 is directly connected to the temperature receiving device through the wire core of the second end 102, the solution of this example is lower in cost because the wire member is omitted, compared to the solution of providing the wire member and the temperature receiving device described above.

As shown in fig. 3 to 8, the compressor upper cover 2 is provided with a through hole 220 through which the extension portion 3 extends, and the extension portion 3 is in sealing engagement with the through hole 220 to prevent leakage of refrigerant gas in the compressor 100.

Alternatively, the extension 3 is in sealing engagement with the via 220 by means of an interference fit. Alternatively, as shown in fig. 3 and 4, a sealing sleeve 15 may be sleeved between the protruding portion 3 and the via 220, and the protruding portion 3 is in sealing engagement with the via 220 through the sealing sleeve 15. Alternatively, as shown in fig. 7, the protruding portion 3 and the via 220 may be in sealing engagement with each other by using a sealant 17, wherein the sealant 17 may be a high-temperature and high-pressure resistant screw thread.

As shown in fig. 1, the compressor upper cover 2 includes a cover body 21 and a connection block 22, and the cover body 21 is provided with a connection hole 210 penetrating therethrough.

The through hole 220 is provided in the connection block 22, and allows the compressor upper cover 2 to extend out of the extension portion 3 through the connection block 22.

In the above example, the cover 21 of the upper cover 2 of the compressor is generally of an integrally formed structure, and the connection block 22 is separately provided for the extension portion 3 of the temperature measuring wire 1 to be installed, so that the connection block 22 can be designed and separately processed according to the shape of the extension portion 3, and the processing is more convenient.

As shown in fig. 7, a stop table 25 may be disposed on an outer wall of the connection block 22, where the stop table 25 is used to abut against an end surface of the cover 21, so as to stop and limit a depth of the connection block 22 inserted into the connection hole 210. Wherein, when the stop table 25 abuts against the end face of the cover 21, the connection block 22 is mounted in place.

As shown in fig. 3 and 4, when the second end 102 of the temperature measuring wire 1 is provided with a wire connecting piece, the wire connecting piece is used as the extending portion 3, and the wire connecting piece is the joint 32, the sealing sleeve 15 is sleeved between the joint 32 and the via hole 220, and the joint 32 is in sealing fit with the via hole 220 through the sealing sleeve 15. The hole wall of the via 220 is provided with a step 2201, and the sealing sleeve 15 is fixedly connected with the connecting block 22, for example, the sealing sleeve 15 is welded and fixed with the connecting block 22. The gland 15 secures the fitting 32 against the step 2201.

In the above example, when the connection element is the connector 32, the sealing sleeve 15 can not only realize the sealing between the connector 32 and the via hole 220, but also support the connector 32 in the via hole 220 through the cooperation of the connection element and the sealing sleeve 15, so that the sealing sleeve 15 has the advantages of one dual-purpose structure, simplified structure and compact structure.

Further, as shown in fig. 4, a stop step 151 may be provided in the sealing sleeve 15, and a limiting table 320 is provided on the outer wall of the joint 32. The sealing sleeve 15 abuts against the limiting table 320 of the joint 32 through the stop step 151 so as to fix the joint 32 on the step 2201.

In the above example, the stop step 151 on the seal sleeve 15 mates with the stop abutment 320 on the nipple 32, allowing the seal sleeve 15 to apply a force to the nipple 32, securing the nipple 32 against the step 2201 in the via 220.

As shown in fig. 4, the above-mentioned joint 32 may have an outer joint section 321 and an inner joint section 322 connected in sequence, the joint 32 being connected to the second end 102 of the temperature measuring wire 1 through the inner joint section 322, and the joint 32 being connected to the temperature receiving device through the outer joint section 321.
