Description

Technical Field

[0001] This application relates to the technical field of insect-proof devices, and more particularly to an insect-proof device for a box and a heat pump device. Background Technology

[0002] As a core component of heating and cooling systems, heat pump outdoor units are often installed in areas where insects are active, such as courtyards and green belts. In actual use, insects can easily gnaw on the insulation of the unit's connecting cables and may also enter the unit through gaps between the cables and the equipment casing, causing a series of problems. These can range from minor issues like signal transmission interference and cable short circuits to more serious problems such as damage to core components, equipment malfunctions, and even electrical safety accidents, severely impacting the operational stability and safety of the heat pump system.

[0003] Existing protection solutions for cables of heat pump outdoor units generally suffer from limitations in functionality and design. On the one hand, traditional protection structures cannot simultaneously meet the dual requirements of cable securing and insect-proof sealing, failing to balance installation stability and insect-proof reliability. On the other hand, existing protection solutions often employ a modular design, requiring the separate assembly of multiple independent components such as cable sheaths, cable ties, and insect-proof seals. This not only complicates installation procedures, increases construction difficulty and costs, but also makes protection prone to failure due to dimensional incompatibility and assembly gaps between components. Consequently, it increases the frequency and cost of subsequent maintenance, making it difficult to meet the long-term stable operation requirements of heat pump outdoor units. Utility Model Content

[0004] The purpose of this application is to provide a box-type insect prevention device and a heat pump device to solve the technical problems existing in the prior art.

[0005] To achieve the above objectives, this application adopts the following technical solution: On one hand, a box-type insect-proof device is provided, including: a mounting base and a protective sleeve integrally formed on the mounting base. The inner sides of the mounting base and the protective sleeve form a cable passage for cables to pass through. A clamping member is provided at one end of the protective sleeve away from the mounting base. The clamping member is used to clamp the port of the protective sleeve so that the inner wall of the protective sleeve is in close contact with the cable.

[0006] Furthermore, the protective sleeve has a channel around its port, the clamping member passes through the channel, and a portion of the clamping member is exposed outside the channel.

[0007] Furthermore, the clamping component is a cable tie.

[0008] Furthermore, the clamping element is a rope, and both ends of the rope are exposed outside the channel.

[0009] Furthermore, the protective sleeve is made of a flexible material.

[0010] Furthermore, the flexible material includes one or more combinations of polyvinyl chloride, polyethylene, polytetrafluoroethylene, fluororubber, and silicone rubber.

[0011] Furthermore, the mounting base is made of metal or plastic.

[0012] Furthermore, the outer peripheral surface of the mounting base is provided with a positioning groove.

[0013] Furthermore, the mounting base is provided with a locking hole.

[0014] On the other hand, a heat pump device is also provided, including: a housing and the above-described insect-proof device for the housing, wherein the mounting base is fixed to the inside of the housing.

[0015] The beneficial effects of this application are as follows: By integrating the mounting base and the protective sleeve into one piece, the separate assembly process of components such as the protective sleeve and cable ties in the traditional split solution is eliminated, simplifying the installation process and avoiding protection failure caused by component mismatch; at the same time, by using the clamping parts at the end of the protective sleeve to clamp the port, the inner wall of the protective sleeve is tightly attached to the cable, which can simultaneously achieve cable clamping and insect-proof sealing, effectively solving the problem of single function in the traditional solution, reducing the later maintenance cost, and improving the stability and safety of the heat pump outdoor unit operation.

[0019] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0022] like Figures 1-3 As shown, this embodiment provides a box-type insect prevention device, including: a mounting base 1 and a protective sleeve 2 integrally formed on the mounting base 1. The inner sides of the mounting base 1 and the protective sleeve 2 form a cable passage 4 through which a cable can pass. The protective sleeve 2 is provided with a clamping member 3 at one end away from the mounting base 1. The clamping member 3 is used to clamp the port of the protective sleeve 2 so that the inner wall of the protective sleeve 2 is in close contact with the cable.

[0023] Based on the above scheme, the device adopts an integrated structure of mounting base 1 and protective sleeve 2. Compared with the traditional split protection scheme, which requires separate installation of protective sleeve, cable tie 301 and insect-proof components, the device can be directly assembled through mounting base 1, which greatly simplifies the installation process and reduces construction difficulty and installation cost. At the same time, the integrated structure avoids the specification mismatch problem between independent components, fundamentally reducing the risk of protection failure caused by assembly gaps and improving the reliability of the protection structure.

[0024] Meanwhile, the protective sleeve 2 is equipped with a clamping member 3 at the end opposite to the mounting base 1. When the cable passes through the cable passage 4 formed by the mounting base 1 and the protective sleeve 2, the clamping member 3 clamps the port of the protective sleeve 2, which can make the inner wall of the protective sleeve 2 fit tightly against the outer wall of the cable. This not only achieves the tight fixing of the cable and prevents the cable from loosening and shifting, but also blocks the path of insects to bite the cable insulation layer and enter the equipment from the cable gaps through the tight fit structure. It simultaneously meets the dual requirements of tight fixing and insect prevention and sealing, effectively avoiding problems such as signal interference, cable short circuits, and equipment failures, ensuring the long-term stable and safe operation of the heat pump outdoor unit, and reducing the frequency and cost of later maintenance.

[0025] Furthermore, the outer periphery of the port of the protective sleeve 2 is provided with a channel 201, and the clamping member 3 passes through the channel 201, with a portion of the clamping member 3 exposed outside the channel 201. The channel 201 on the outer periphery of the port of the protective sleeve 2 provides a dedicated installation path for the clamping member 3, allowing the clamping member 3 to be stably arranged around the outer periphery of the port of the protective sleeve 2; at the same time, the design of the clamping member 3 being partially exposed outside the channel 201 facilitates the operator to perform operations such as tightening and fixing the clamping member 3. The design of the channel 201 ensures that the clamping member 3 is evenly distributed along the outer periphery of the protective sleeve 2 port during the clamping process, avoiding the problem of inconsistent tightening of the port caused by the displacement of the clamping member 3 or uneven local force. This ensures that the inner wall of the protective sleeve 2 fits tightly with the outer wall of the cable, improving the reliability of the insect-proof seal. The exposed part of the clamping member 3 simplifies the operation process, allowing operators to easily complete the clamping action without additional tools, further reducing the installation difficulty and improving construction efficiency. At the same time, it ensures the structural stability after clamping and reduces the risk of protection failure due to improper operation.

[0026] The clamping component 3 is a cable tie 301. The cable tie 301 is inserted into the channel 201 around the outer periphery of the port of the protective sleeve 2. Utilizing the characteristics of the cable tie 301 that can tighten in one direction and has a self-locking function, by tightening the portion of the cable tie 301 exposed in the channel 201, the cable tie 301 can be driven to shrink around the channel 201, thereby forcing the port of the protective sleeve 2 to tighten synchronously, and finally achieving a tight fit between the inner wall of the protective sleeve 2 and the outer wall of the cable.

[0027] As a mature fastening component, cable tie 301 is simple and intuitive to operate. Operators can tighten and fix the cable without the need for complicated tools, which significantly improves the convenience of the clamping operation and further simplifies the installation process. At the same time, the self-locking function of cable tie 301 ensures that the port of the protective sleeve 2 remains stable after tightening, preventing loosening due to vibration, external force, or other factors. This maintains a tight fit between the protective sleeve 2 and the cable for a long time, continuously and reliably blocking the entry path of insects and enhancing the durability of the insect-proof seal. In addition, cable tie 301 is low in cost, highly versatile, easy to obtain and replace, which helps to reduce the overall cost of the device and improve its economic efficiency and feasibility in practical applications.

[0028] Optionally, the clamping member 3 is a rope 302, with both ends of the rope 302 exposed outside the channel 201. The rope 302 is inserted into the channel 201 around the outer periphery of the protective sleeve 2 port. Utilizing the flexibility of the rope 302, by tightening and securing the exposed ends, the rope 302 can be driven to wrap around and contract along the channel 201, thereby causing the protective sleeve 2 port to tighten synchronously, so that the inner wall of the protective sleeve 2 fits tightly against the outer wall of the cable. Rope 302, as the clamping component 3, is made from widely available and inexpensive materials, making it easy to obtain and replace, which helps reduce the overall cost of the device. Its exposed ends allow operators to tighten and fix the device manually without relying on special tools, making the operation simple and flexible, further simplifying the installation process and improving construction convenience. At the same time, the flexibility of rope 302 can adapt to the contraction shape of the protective sleeve 2's ends, ensuring uniform force during tightening and avoiding local over-tightening or over-loosening. This ensures the tightness of the protective sleeve 2 against the cable, continuously and reliably blocking the insect intrusion path, guaranteeing the stability of the insect-proof sealing effect, and reducing the later maintenance costs caused by protective failure.

[0029] In some embodiments, the protective sleeve 2 is made of a flexible material. When the protective sleeve 2 is made of a flexible material, the flexible material itself is flexible and easily deformable. Under the action of the clamping member 3, the protective sleeve 2 can adapt to the clamping force and deform accordingly, thereby better conforming to the outer contour of the cable. Moreover, the flexibility of the flexible material allows it to adapt to slight shaking or minor position adjustments of the cable during use, maintaining a close fit with the cable.

[0030] In this design, the deformable properties of the flexible material allow the protective sleeve 2 to fit more fully with cables of different diameters and surface shapes when tightened, avoiding gaps caused by excessively hard materials. This significantly improves the sealing tightness between the protective sleeve 2 and the cable, enhancing the insect-proof effect. In addition, the flexibility of the flexible material reduces the operational difficulty of the protective sleeve 2 during installation, facilitating cable threading and tightening of the clamping parts 3, thus improving installation convenience. At the same time, its adaptable deformation characteristics reduce loosening of the fit caused by slight cable displacement or vibration, maintaining the sealing effect over a long period, further reducing the risk of protection failure, and ensuring the long-term reliability of the device.

[0031] Specifically, the flexible material includes one or more combinations of polyvinyl chloride (PVC), polyethylene (PE), polytetrafluoroethylene (PTFE), fluororubber, and silicone. The selected PVC and PE materials are mature flexible polymer materials, widely available and cost-controllable, which helps reduce the mass production cost of the device. Fluororubber and silicone materials improve the environmental adaptability of the protective sleeve 2, allowing it to maintain good flexibility and sealing under outdoor temperature variations, humidity, or slight chemical corrosion, preventing protective failure due to material aging and cracking. Furthermore, these materials all possess certain mechanical strength and anti-biting capabilities, directly resisting insect bites and damage to the protective sleeve 2 itself, further protecting the internal cable insulation layer. The compatibility of multiple materials also meets the needs of different usage scenarios; for example, fluororubber and silicone can be used in high-temperature environments, while PVC and PE can be used in ordinary courtyard environments, improving the device's scenario applicability and performance specificity.

[0032] It is worth mentioning that, based on the specific requirements for flame retardancy and high-temperature resistance in particular application scenarios, the material composition of the protective sleeve 2 can be adjusted or a base material with corresponding properties can be selected. This allows the protective sleeve 2 to maintain flexibility while possessing targeted properties such as flame retardancy and high-temperature resistance, thus adapting to special environmental requirements. Customized material design enables the protective sleeve 2 to flexibly adapt to different application scenarios. For environments with requirements for flame retardancy and high-temperature resistance, special performance requirements can be met through material adjustments, improving the device's scenario adaptability and safety.

[0033] In addition, for maintenance-free units, the heat-shrinkable material is used to shrink when heated. Heat-shrinkable sections are installed at both ends or key nodes of the protective sleeve 2. After the cable is installed, the heat-shrinkable sections shrink by heating, automatically and tightly wrapping the cable or terminal block. This eliminates gaps without the need for additional clamping parts 3, achieving a sealed fixation. On the one hand, it eliminates the clamping parts 3, simplifying the device structure and installation process, and avoiding the loosening and aging problems that may occur with long-term use of clamping parts 3. On the other hand, after the heat-shrinkable sections shrink, they can form a tight wrap with the cable and terminal block, completely eliminating gaps, enhancing the insect-proof sealing effect, and meeting the requirements of maintenance-free operation. This reduces subsequent maintenance intervention, lowers maintenance costs, and ensures long-term reliable operation of the device.

[0034] Optionally, the mounting base 1 is made of metal or plastic. When the mounting base 1 is made of metal, the rigidity and structural stability of the metal allow for a secure connection with the sheet metal housing or sheet metal components of the heat pump equipment via welding, screwing, or other methods. When the mounting base 1 is made of plastic, the compatibility and adaptability of the plastic material with plastic parts allow for a stable connection with the plastic housing or plastic components of the equipment via snap-fit, heat fusion, screwing, or other methods.

[0035] In the above solution, the material of mounting base 1 is selected specifically according to the connected object, which can ensure that it forms a strong and fixed connection with the casing or related components of the heat pump outdoor unit. This avoids problems such as loose connection or excessive gap due to material mismatch, ensuring the stability of the entire insect prevention device from the installation foundation and reducing the risk of protection failure caused by loose mounting base 1. At the same time, a reliable connection can be achieved without the need for additional adapter parts, simplifying the installation process, reducing the cost increase and compatibility deviation caused by adapter parts, improving the adaptability of the device to equipment casings of different materials, and further enhancing the practicality and reliability of the overall protection structure.

[0036] In some embodiments, the outer peripheral surface of the mounting base 1 is provided with a positioning groove 101. The positioning groove 101 can engage with positioning protrusions, locking blocks, or other mating structures on the heat pump equipment housing or corresponding mounting components to form a precise constraint on the circumferential or axial position of the mounting base 1 during installation, ensuring that the mounting base 1 is fixedly connected to the equipment in a preset position and avoiding offset or misalignment during installation. By engaging with the mating structure on the equipment, the positioning groove 101 can significantly improve the positioning accuracy of the mounting base 1, preventing misalignment between the cable passage 4 and the equipment cable inlet due to installation offset, and ensuring smooth cable threading. The engagement and limiting structure enhances the stability of the connection between the mounting base 1 and the equipment, reducing the loosening of the mounting base 1 due to vibration, external forces, or other factors during long-term use, thereby maintaining a tight fit between the protective sleeve 2 and the cable, ensuring the continuity of the insect-proof sealing effect. In addition, the positioning groove 101 provides a clear alignment reference for the installation process, simplifying the installation operation steps, reducing the probability of rework due to improper position adjustment, improving installation efficiency, and further reducing installation costs and the risk of adaptation deviation.

[0037] Meanwhile, the mounting base 1 is also provided with locking holes. The locking holes, combined with the fasteners, significantly enhance the connection strength between the mounting base 1 and the equipment, effectively resisting displacement or loosening of the mounting base 1 caused by vibration, external impact, or other factors, fundamentally ensuring the installation stability of the entire insect-proof device. Rigid fixing ensures that the relative position of the mounting base 1 and the equipment remains precise, preventing misalignment between the cable passage 4 and the equipment cable inlet, ensuring smooth cable routing and maintaining the proper fit between the protective sleeve 2 and the cable, thus continuously maintaining the insect-proof sealing effect. Furthermore, the locking holes provide clear and standardized fastening points for installation, allowing operators to quickly complete the fixing using conventional tools, improving installation efficiency and reliability, and reducing the risk of protection failure and subsequent maintenance costs caused by insecure fixing.

[0038] In summary, the insect-proof device for the enclosure in this application, through integrated design and optimized structure, brings many significant benefits: First, the integrated structure of mounting base 1 and protective sleeve 2 is adopted, which integrates the fixing function, cable protection function and sealing and fastening function into one. Compared with the traditional split structure, the functions are more concentrated and the coordination is stronger, avoiding the adaptation problems caused by the dispersion of split components.

[0039] Secondly, it significantly improves installation and disassembly efficiency. By adopting a retractable clamping component 3, the installation process is simplified to two steps: putting on the protective sleeve 2 and tightening the clamping component 3, eliminating the cumbersome steps in the traditional split-type solution. When disassembling and adjusting after the service, it is only necessary to loosen the clamping component 3 to operate, which solves the problems of time consumption, easy omission, and inconvenience in after-sales service caused by the repeated cutting and binding of the traditional disposable cable tie 301, and significantly reduces construction and maintenance costs.

[0040] Furthermore, it effectively improves insect-proof sealing and durability. The integrated structure, combined with the tight fit between the protective sleeve 2 and the cable, avoids the risk of pest intrusion caused by the loosening of the cable tie 301 and gaps at the ports in the traditional split structure. At the same time, the device body and the clamping part 3 age synchronously, maintaining a stable fit over a long period of time. This solves the problems of relative sliding between the sheath and the cable and the easy aging and breakage of the cable tie 301 in the split structure, ensuring the durability of the protective effect.

[0041] In addition, it has stronger adaptability. The integrated structure only needs to consider the maximum cross-sectional area of ​​the cable in the cable passage 4, and can be backward compatible with different specifications of cables. It solves the problem that the cable tie 301 and the sheath need to be matched separately in the traditional split structure, which is easy to cause inconvenience or loosening due to the mismatch. It improves the device's adaptability to a variety of cables.

[0042] Finally, it also has a good organizational effect. The integrated design makes the structure integrated, avoiding the problems of exposed and messy cable ties and loose cable bundles in the traditional split structure. It not only looks neat, but also plays a role in storing cables and improving the overall neatness of the wiring.

[0043] On the other hand, a heat pump device is also provided, including: a housing and the above-mentioned insect-proof device for the housing, wherein the mounting base 1 is fixed to the inner side of the housing.
