Description

Technical Field

[0001] This utility model relates to the field of compressors, and in particular, to a connecting component for connecting a hose equipped with a sensor to a compressor, and a compressor using the connecting component. Background Technology

[0002] Equipment such as compressors are configured in heat pump systems to achieve pressure and temperature conversion of the medium within the system. To extend the lifespan of the heat pump system and to more precisely control its operation, sensors such as temperature probes are placed in the high-pressure chamber of the compressor.

[0003] The high-pressure chamber contains a high-temperature, high-pressure medium. While placing the sensor near the medium outlet, it's crucial to ensure it won't detach or move during compressor operation. FEP (fluorinated ethylene propylene copolymer) tubing is commonly used to encapsulate the sensor, and both the sensor and the FEP tubing are installed together at the designated location within the high-pressure chamber.

[0004] To position the sensor and FEP hose, a positioning element is fixed to a specific location on the FEP hose. During sensor installation, the operator must use a press-fit device, such as a press-fitting tool, to press the positioning element into the compressor. This compressor configuration makes disassembly and assembly inconvenient and easily damages the positioning element due to factors such as misoperation or press-fitting malfunctions, resulting in unnecessary economic losses. Furthermore, this compressor configuration makes it difficult to ensure that the sensor does not move due to factors such as media flow or press-fitting angle deviation, affecting the sensor's sensing quality. Utility Model Content

[0005] In view of this, the present invention provides a connecting component for connecting a hose to the frame of a compressor. The connecting component includes: a connector body that can be fixed to a mating hole in the compressor frame; a locking member supported in the connector body and configured to at least partially be oblique to the central axis of the connector body; and a release member movably connected to the connector body, having a first position and a second position. When the release member is in the first position, the locking member allows the hose to enter the mating hole in the frame through the connecting component; when the release member is in the second position, the locking member selectively allows the hose to enter or exit the mating hole in the frame.

[0006] This connection design, which mates with the mating holes in the frame, allows the hose to be positioned as desired by the compressor. Compared to hoses that are press-fitted using traditional positioning components, this connection design ensures accurate hose positioning, simplifies assembly and disassembly, and reduces the risk of hose damage, effectively lowering production costs.

[0007] Furthermore, the connecting component configured in this way includes a release element with a first position and a second position. When the release element is in the first position, the connecting component allows the hose to move into the mating hole of the frame until it reaches its limit position, but does not allow the hose to leave the mating hole of the frame; when the release element is in the second position, the connecting component allows the hose to freely enter or leave the mating hole of the frame. The operator must apply an operation to the release element before the hose can freely enter or leave the mating hole of the frame. This connecting component configuration can prevent inaccurate hose positioning caused by factors such as impact and vibration.

[0008] In one example, the locking member includes a receiving portion and a locking portion, the locking portion including an elastic member extending radially inward from the receiving portion. When the release member is in a first position, the minimum radial dimension of the locking portion is less than the outer diameter of the hose; when the release member is in the first position and the hose passes through the connecting member, the minimum radial dimension of the locking portion is equal to the outer diameter of the hose; when the release member is in a second position, the minimum radial dimension of the locking portion is greater than the outer diameter of the hose.

[0009] The connecting component, configured in this way, has a locking part supported within the connector body, obliquely intersecting the central axis of the connector body, and having a minimum radial dimension smaller than the outer diameter of the hose. When the release element is in the first position and the hose enters the connecting component, because the minimum radial dimension of the locking part is smaller than the outer diameter of the hose, at least a portion of the locking part abuts against the outer surface of the hose, causing the locking part to deform, increasing its minimum radial dimension to equal the outer diameter of the hose. When the release element is in the second position, due to further deformation of the locking part, its minimum radial dimension is larger than the outer diameter of the hose. At this point, the locking part no longer abuts against the hose, and the hose can freely enter or exit the mating hole of the frame.

[0010] In one example, the locking part includes multiple tongues spaced circumferentially.

[0011] The locking part, designed in this way, has multiple tongues, ensuring that the portion contacting the outer surface of the hose provides sufficient resistance to prevent the hose from leaving the mating hole in the frame. Furthermore, the multiple tongues are spaced circumferentially, ensuring that the locking part can deform more easily, reducing the risk of damage to the connecting components.

[0012] In one example, the connector body includes a first end and a second end opposite to the first end, the second end being connected to a release element, and the outer diameter of the connector body continuously decreasing from the second end to the first end.

[0013] This design allows the connector body to be more easily inserted into the frame, preventing damage to the connecting components during installation due to factors such as inaccurate angles. The connector body enters the frame through a mating hole at the first end, and a release mechanism at the second end helps prevent the connector body from being inserted too deeply, which could cause operational inconvenience.

[0014] In one example, the connector body includes a radial positioning portion, which is a protrusion distributed circumferentially along the outer surface of the connector body, the protrusion being configured to abut against a mating hole in the frame.

[0015] The radial positioning part designed in this way can reduce the accuracy requirements of the connector body, and ensure a stable connection between the connector body and the frame while allowing the connector body to enter the frame more easily.

[0016] In one example, the connector body includes a first limiting part, and the release member includes a second limiting part. When the release member is in the first position, the first limiting part abuts against the second limiting part.

[0017] By providing a first limiting part and a second limiting part, the release member is movably connected to the connector body, and the sensor body is stably held in the first position by the first limiting part and the second limiting part when not receiving a release operation.

[0018] In one example, the release element includes a contact portion that forms an angle α2 with the central axis of the connector body; the locking element includes a locking portion that forms an angle α1 with the central axis of the connector body, where α2 < α1.

[0019] The contact portion is designed in this way to easily guide the deformation of the locking portion and to ensure that the minimum size of the final locking portion in the radial direction is greater than the outer diameter of the hose, so that the hose can freely enter or leave the mating hole of the frame.

[0020] In one example, the release element includes an operating section that is at least partially exposed outside the rack.

[0021] In one example, the operating unit is adapted to receive a release operation so that the release element moves from a first position to a second position.

[0022] This release mechanism allows for easy acceptance of release operations, facilitating the installation and removal of hoses and sensors.

[0023] In one example, the release operation includes a pressing operation in the direction of entry of the hose.

[0024] The release mechanism designed in this way can switch between the first and second positions, and by setting the direction of the pressing operation, it can prevent the connection parts from restricting the hose and sensor from leaving the blind hole due to misoperation during the process of the hose and sensor entering the blind hole.

[0025] In one example, the connector body and the locking element are integrally molded.

[0026] On the other hand, the present invention provides a compressor, including a first component and a frame, wherein the first component is provided with a blind hole, the frame has a mating hole communicating with the blind hole, and a hose is connected to the mating hole of the frame and extends into the blind hole through a connecting component in any of the above examples.

[0027] In one example, a sensor is installed in the hose.

[0028] This compressor design allows the connecting components to mate with mating holes in the frame and, consequently, with blind holes (and closed ends) in the first component, enabling the hose and sensor to be positioned as desired by the compressor. This compressor design ensures accurate positioning of the hose and sensor, simplifies assembly and disassembly, minimizes damage to the hose and sensor, and effectively reduces production costs. Because the blind hole size corresponds to the hose configuration, this compressor design also reduces the impact of media flow and shocks on the sensor during operation, ensuring sensor sensing quality.

[0040] Numerous specific details are set forth below to provide an understanding of the structure, function, and use of the embodiments described and illustrated in the specification and figures. It is to be understood that the embodiments described and illustrated herein are non-limiting examples, and thus it will be appreciated that the particular structural and functional details disclosed herein are representative and exemplary. Variations and changes may be made to these embodiments without departing from the scope of the claims.

[0041] refer to Figure 1 The heat pump system 1 includes a compressor 4 and a heat exchange medium 5. The compressor 4 includes a frame 20, a first component 40, a high-pressure chamber 41, and a low-pressure chamber 42. The heat exchange medium 5 absorbs heat and expands by exchanging heat with the outside environment, and then flows into the compressor 4. Through the operation of components such as the crankshaft, piston, and housing of the compressor 4, the heat exchange medium 5 is pressurized and flows out of the high-pressure chamber 41 through the outlet in a high-temperature and high-pressure state.

[0042] For the purpose of more precise control of compressor 4 and improving the service life of compressor 4, sensor 2 is arranged in high-pressure chamber 41. Sensor 2 is configured near the outlet gas to sense the state of heat exchange medium 5 in high-pressure chamber 41, providing a basis for subsequent control of compressor 4. Optionally, sensor 2 is one or more of temperature sensor, pressure sensor, and leak detector.

[0043] To extend the service life of sensor 2 under high temperature and high pressure environments, a protective element is used to protect sensor 2. The protective element can be a heat shrink tubing made of materials such as polytetrafluoroethylene (FETP) or soluble polytetrafluoroethylene (PFA). Preferably, the protective element is a flexible tube 3 made of fluorinated ethylene propylene copolymer (FEP). Before placing sensor 2 in the high-pressure chamber 41, sensor 2 can be placed inside the flexible tube 3. By heating and shrinking a portion of the flexible tube 3, sensor 2 is encapsulated in a specific position within the flexible tube 3. The flexible tube 3 thus achieves both positioning and protection of sensor 2.

[0044] This application provides a connecting component for connecting the aforementioned hose 3 to a compressor. Using this connecting component, the hose 3 can be quickly and easily installed into the compressor frame, thereby enabling the placement of a sensor 2, located within the hose 3, into the compressor, such as into the high-pressure chamber, to sense the compressor's condition and achieve more precise control of the heat pump system's operation. Simultaneously, by using this connecting component, the hose 3 can also be easily removed from the compressor, allowing for convenient replacement of the hose or the sensor within it.

[0045] The following will refer to Figures 2 to 8 The detailed structure of the connecting component according to embodiments of this application will be described in detail below. (See reference...) Figures 2 to 8 It can be seen that at least a portion of the connecting component 10 is embedded in the frame 20 of the compressor 4. More specifically, the frame 20 is provided with a through hole 7, also called a mating hole 7, in which the connecting component 10 is at least partially disposed. That is, one end of the connecting component 10 is placed in the external environment and the other end is placed in the frame 20.

[0046] The compressor 4 includes a first component 40, in which a blind hole 30 is provided, and a mating hole 7 in the frame 20 communicates with the blind hole 30. By way of example only, the first component 40 may be a stationary scroll plate of the compressor 4. The inner diameter of the blind hole 30 is adapted to the outer diameter of the hose 3, and its length is adapted to the position of the sensor 2 in the hose 3. During the installation of the sensor 2 into the compressor 4, the sensor 2 and the hose 3 are first passed through the connecting component 10 into the mating hole 7, and then into the blind hole 30; that is, the sensor 2 and the hose 3 are guided into the first component 40 of the compressor 4. The blind hole 30 then guides the hose 3 and the sensor 2 to continue into its trajectory until the hose 3 and the sensor 2 contact the closed end 31 of the blind hole 30. At this point, the hose 3 and the sensor 2 cannot continue into the first component 40; that is, the hose 3 and the sensor 2 are limited at least in the direction of entry.

[0047] The connecting component 10 includes a connector body 11, a locking element 12, and a releasing element 13. The connector body 11 can be fixedly connected to the frame 20, serving to support the locking element 12 and the releasing element 13. By way of example only, the connector body 11 can be configured to be cylindrical or at least partially cylindrical to facilitate the passage of the hose 3. Optionally, the connector body 11 includes a first end 110 and a second end 120. When the connector body 11 is connected to the frame 20, the first end 110 of the connector body 11 contacts the frame 20 first, at which time the second end 120 of the connector body 11, opposite to the first end 110, faces the external environment and connects to the releasing element 13. The outer diameter of the connector body 11 can be configured to continuously decrease from the second end 120 to the first end 110, thereby facilitating the insertion of the connecting component 11 into the mating hole 7 of the frame 20.

[0048] The connector body 11 may include a radial positioning portion 111. The radial positioning portion 111 is configured to abut against the inner wall of the mating hole 7 to position the connecting member 10 at least in the radial direction. By way of example only, the radial positioning portion 111 may be configured as an annular protrusion distributed circumferentially along the outer surface of the connector body 11. Preferably, the protrusion dimension of the radial positioning portion 111 may be configured to gradually decrease towards the first end 110 to allow the connector body 11 to easily enter the mating hole 7.

[0049] The connector body 11 may include a plurality of radial positioning portions 111. Optionally, the plurality of radial positioning portions 111 are distributed at intervals along the axial direction of the connector body 11. Preferably, two radial positioning portions 111 are distributed at intervals along the axial direction of the connector body 11. The radial positioning portions 111 arranged in this way can reduce the accuracy requirements of the connector body 11, reduce the risk of the connecting component 10 falling off, thereby achieving a stable connection between the connecting component 10 and the frame 20.

[0050] The connector body 11 may also include a receiving portion 112. By way of example only, the receiving portion 112 may be configured as a groove distributed circumferentially along the inner surface of the connector body 11, or it may be configured as a slot, tooth, positioning protrusion, etc., extending axially along the inner surface of the connector body 11, as long as the receiving portion 112 can receive at least a portion of the locking member 12 and support the locking member 12 during the use of the connecting member 10, ensuring that the locking member 12 is in continuous contact with the hose 3.

[0051] Preferably, the receiving portion 112 is a groove distributed circumferentially along the inner surface of the connector body 11, and includes an arc-shaped positioning block 1121 protruding toward the second end 120 on the bottom surface of the receiving portion 112. The arc-shaped positioning block 1121 is configured to cooperate with the receiving portion 123 of the locking member 12 to ensure that the support member 12 is stably held in the connector body 11 while being guided to deform.

[0052] The connector body 11 may further include a first limiting portion 113 and a movable space 114. The first limiting portion 113 supports the release member 13. The movable space 114 is adapted to allow the release member 13 to move between a first position and a second position. By way of example only, the first limiting portion 113 is a radially inwardly extending support surface, and the movable space 114 is an annular space disposed on the inner surface of the connector body 11. When the connecting member 10 is installed in the frame 20, the release member 13 abuts against the first limiting portion 113 under the action of gravity. When the release member 13 receives a release operation, the release member 13 separates from the first limiting portion 113 and is able to move a certain distance within the movable space 114. When the release member 13 stops receiving a release operation, the release member 13 is able to automatically move in the opposite direction under the action of gravity and the locking member 12 until it abuts against the first limiting portion 113.

[0053] The locking element 12 can be a thin elastic element. It should be noted that the term "elastic element" in this utility model refers to a component that can undergo elastic deformation to accumulate potential energy and release potential energy through elastic recovery, and is not limited to a specific material; preferably, the locking element 12 is a spring clip.

[0054] The locking member 12 may include a receiving portion 123 and a locking portion 121. By way of example only, the receiving portion 123 is configured as an axially distributed arcuate groove recessed toward the second end 112. The receiving portion 123 can cooperate with the arcuate positioning block 1112, and when the locking member 12 abuts against the releasing member 13, the locking portion 121 elastically deforms toward the first end 110, and the curvature of the arc of the receiving portion 123 is adaptively reduced. This reduces the risk of the locking member 12 disengaging from the connector body 11, achieving a more stable connection.

[0055] The locking part 121 is configured as a spring piece extending radially inward from the receiving part 123, and forms an angle α1 with the axis Z of the connector body 11 along the surface of the locking part 121. The minimum radial dimension L1 of the locking part 121 is smaller than the outer diameter L2 of the hose 3. When the hose 3 extends into the connecting member 10 along the axis Z, the locking part 121 deforms, L1 increases to be equal to L2, and α1 decreases accordingly. At this time, at least a portion of the locking part 121 abuts against the outer surface of the hose 3. Under the action of the frictional force generated by the abutment and the elastic potential energy accumulated in the locking part 121, the hose 3 can only enter the connecting member 10 and is restricted from leaving the connecting member 10. At this time, the hose 3 and the sensor 2 are limited at least in the departure direction.

[0056] Preferably, the locking part 121 is a plurality of tongues spaced apart along the axial direction. The locking part 121 may also be in other forms, as long as they can achieve a similar effect.

[0057] In this embodiment of the invention, the connecting component 10 further includes a locking element 12. Optionally, the connecting component 10 includes multiple locking elements 12. The locking elements 12 can be integrally formed with the connector body 11 or can be manufactured separately for installation in the connector body 11, as long as they can achieve similar effects.

[0058] Preferably, the locking element 12 is made of metal material by stamping.

[0059] The release member 13 includes a second limiting portion 131. The second limiting portion 131 functions to cooperate with the first limiting portion 113, such that when the release member 13 is in the first position, the release member 13 abuts against the first limiting portion 113, but not against the locking member 12. Preferably, the second limiting portion 131 is a protrusion extending radially outward along the outer surface of the release member 13. Preferably, the second limiting portion 131 is an arc-shaped protrusion. This configuration of the second limiting portion 131 allows for easier installation into the connector body 11 and easier movement within the movement space 114.

[0060] The release member 13 also includes a contact portion 132. By way of example only, the contact portion 132 is an inclined surface that forms an angle α2 with the axis Z, where α2 < α1. The contact portion 132 configured in this way will first contact the locking portion 121 and cause the locking portion 121 to continue to deform, ensuring that α1 can be easily reduced to at least equal to α2.

[0061] The locking member 12 and the releasing member 13 cooperate. When the releasing member 13 is in the first position, the contact portion 132 does not contact the locking member 12, and the locking member 12 abuts against the outer surface of the hose 3, allowing the hose 3 and sensor 2 to enter the mating hole 7 and subsequently into the blind hole 30, without being able to move in the reverse direction. When the releasing member 13 is in the second position, the contact portion 132 contacts the locking portion 121, and the locking portion 121 deforms, α1 continues to decrease until it equals α2, and L1 increases to be greater than L2. At this time, the contact portion 132 abuts against the locking portion 121, and the locking portion 121 separates from the outer surface of the hose 3, which allows the hose 3 to freely enter or exit the mating hole 7 and / or the blind hole 30.

[0062] The release element 13 also includes an operating section 133. Optionally, the operating section 13 is an operating plane perpendicular to the inlet direction of the hose 3. The operating section 13 is exposed outside the frame 20 to receive a release operation from the operator. Optionally, the release operation is a pressing operation along the inlet direction of the hose 3. The operating section 133, thus configured, can easily receive release operations, facilitating the installation and removal of the hose and sensor.

[0063] It should be noted that the elements described in the above specific embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0064] It should be understood that multiple components and / or parts can be provided by a single integrated component or part.

The use of the public designation "a" or "an" to describe a component or part does not imply the exclusion of other components or parts.

[0065] It should be understood that although terms such as "first" or "second" may be used in this invention to describe various elements, these elements are not defined by these terms, which are only used to distinguish one element from another.

[0067] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto.
