Description

Technical Field

[0001] This utility model relates to the field of detachable filter components, and in particular to a heat pump unit with a detachable filter component. Background Technology

[0002] Geothermal heat pump unit filtration equipment is used to filter impurities and contaminants from groundwater or underground hot water. Geothermal heat pump systems use groundwater or underground hot water as a heat source for heating or cooling. However, groundwater or underground hot water may contain impurities such as suspended particles, sediments, silt, algae, as well as rust, rusty water, bacteria, and other contaminants. These impurities and contaminants can adversely affect the operating efficiency of the geothermal heat pump system and the lifespan of the equipment.

[0003] When groundwater or geothermal water passes through a filtration system, impurities are trapped in the filter, while clean water continues to circulate through the system. This reduces the risk of blockage and corrosion of internal pipes, heat exchangers, and other critical components of the geothermal heat pump unit, thereby improving the system's performance and reliability. However, when using the filtration system of a geothermal heat pump unit, the water stored in the heat pump unit is generally pre-filtered to remove particulate impurities and then recirculated into the heat pump unit. Scale buildup during filtration can clog the filtration equipment. Although this can be achieved by installing a filter screen, the screen is inconvenient to disassemble and clean, which can affect the filtration process.

[0004] Therefore, it is essential to provide a heat pump unit with a detachable filter assembly to address the shortcomings of existing technologies. Utility Model Content

[0021] The present invention will be further described in conjunction with the following embodiments.

[0022] Example 1. like Figure 1-3 As shown, a heat pump unit with a detachable filter assembly includes a geothermal heat pump unit body 1, an inlet pipe 2 connected to the inlet of the geothermal heat pump unit body 1, and a detachable filter assembly 3 installed inside the inlet pipe 2.

[0023] like Figure 1-3As shown, the detachable filter assembly 3 includes a straight-through housing 4, which is installed inside the water inlet pipe 2. The straight-through housing 4 has an hourglass-shaped structure and is divided into a middle area housing 5, an inlet end area housing 6, and an outlet end area housing 7. An anti-backflow kit 8 is installed on the outside of the middle area housing 5.

[0024] like Figure 1-3 As shown, a spiral silicone tube 9 is installed on the outside of the water outlet area housing 7, and the end of the water outlet area housing 7 is snapped into the inner wall of the water inlet pipe 2. A metal filter screen 10 is installed inside the water outlet area housing 7, and activated carbon filter cotton 24 is attached to the metal filter screen 10. A one-way filter valve body 11 is installed inside the middle area housing 5.

[0025] By using the hourglass-shaped straight-through housing 4 and the anti-backflow kit 8 installed on the outside of the housing 5 in the middle area, the anti-backflow kit 8 can save space while having a good anti-leakage effect. Furthermore, the spiral silicone tube 9 can provide double protection for the movable snap-fit ​​of the detachable filter assembly 3.

[0026] like Figure 1-3 As shown, the one-way filter valve body 11 includes an annular support plate 12, which is fixedly installed inside the housing 5 in the middle region. A hollow sleeve 13 is fixedly installed on the inner ring of the annular support plate 12. A hollow sleeve 14 is slidably installed inside the hollow sleeve 13. A sealing cover 15 is installed at one end of the hollow sleeve 14. A hollow sleeve guide ring 16 is movably abutted against the outer side of the sealing cover 15. The hollow sleeve guide ring 16 has a circular ring structure, and a silicone pad 21 is installed on the inner ring of the hollow sleeve guide ring 16.

[0027] like Figure 1-3 As shown, the hollow sleeve guide ring 16 is movably engaged with the outer side of the hollow sleeve 14. The outer side of the hollow sleeve guide ring 16 is fixedly installed inside the housing 5 in the middle region. Multiple circular through holes 17 are equidistantly opened on the outer side of one end of the hollow sleeve 14. A spring A 18 is installed on the outside of the hollow sleeve 14. One end of the spring A 18 is fixedly installed on one side of the hollow sleeve 13, and the other end of the spring A 18 is fixedly installed on one side of the hollow sleeve guide ring 16.

[0028] like Figure 1-3 As shown, the anti-backflow kit 8 includes a conical spring 19, with the lower end of the conical spring 19 being the smaller end and the upper end of the conical spring 19 being the larger end. The lower end of the conical spring 19 is fixedly installed on the outside of the housing 5 in the middle region, and the upper end of the conical spring 19 abuts against a rubber water-stop ring 20. The rubber water-stop ring 20 has an umbrella-shaped structure, with the inner ring of the rubber water-stop ring 20 fixedly installed on the outside of the housing 5 in the middle region, and the outer ring of the rubber water-stop ring 20 abutting against the inside of the water inlet pipe 2.

[0029] The conical spring 19 lifts the rubber water-stop ring 20 into an umbrella-shaped structure that abuts against the inner wall of the water inlet pipe 2, which can effectively block the leakage of liquid above the detachable filter assembly 3, thereby preventing liquid from leaking out to the outside of the detachable filter assembly 3.

[0030] The silicone pad 21 installed on the inner ring of the hollow sleeve guide ring 16 can block multiple circular through holes 17 at the bottom of the hollow sleeve 14, thus improving the airtightness of the hollow sleeve guide ring 16.

[0031] like Figure 1-3 As shown, the spiral silicone tube 9 includes a silicone sleeve 22, on which a silicone strip 23 is integrally formed, and the silicone strip 23 is spirally wound around the silicone sleeve 22.

[0032] First, attach and fix the activated carbon filter cotton 24 to the inside of the metal filter screen 10, and then install the metal filter screen 10 into the outlet area housing 7 of the straight-through housing 4; then fix the annular support plate 12 of the one-way filter valve body 11 to the inner wall of the middle area housing 5, and assemble the hollow sleeve 13, hollow sleeve 14, spring A 18 and hollow sleeve guide ring 16 in sequence, and ensure that the sealing cover 15 can tightly abut against the silicone gasket 21 of the guide ring; finally, install the anti-backflow kit 8 on the outside of the middle area housing 5, and install the spiral silicone tube 9 on the outside of the outlet area housing 7 to complete the pre-assembly of the detachable filter assembly 3.

[0033] The pre-assembled detachable filter assembly 3 is inserted into the water inlet pipe 2. It is positioned by the snap-fit ​​structure at the end of the housing 7 in the water outlet area, which engages with the inner wall of the water inlet pipe 2. At the same time, the silicone strip 23 of the spiral silicone cylinder 9 fills the gap between the housing and the pipe, enhancing the sealing performance. In the anti-backflow kit 8, the elastic force of the conical spring 19 pushes the outer side of the umbrella-shaped rubber water-stop ring 20 against the inner wall of the water inlet pipe 2, preventing water from flowing back through the gap.

[0034] When groundwater flows in from the inlet pipe 2, the water first enters the inlet area 6 of the straight-through shell 4. The water pressure pushes the sealing cover 15 to compress the spring A 18, causing the hollow sleeve 14 to slide along the hollow sleeve 13. At this time, the sealing cover 15 separates from the hollow sleeve guide ring 16. The water flows through the circular through hole 17 of the hollow sleeve 14 into the middle area 5, and then flows to the outlet area 7. When it flows through the metal filter screen 10, particulate impurities are intercepted, and the activated carbon filter cotton 24 adsorbs tiny impurities and odors. The filtered water finally enters the geothermal heat pump unit body 1.

[0035] When the filter assembly needs cleaning, simply pull out the removable filter assembly 3. The elastic design of the spiral silicone tube 9 facilitates separation, allowing the metal filter screen 10 and activated carbon filter cotton 24 to be removed separately for cleaning or replacement without disassembling the unit, greatly improving maintenance efficiency.

[0036] This utility model relates to a heat pump unit with a detachable filter assembly. Its core structure includes a geothermal heat pump unit body 1, a water inlet pipe 2, and a detachable filter assembly 3. The water inlet pipe 2 is connected to the water inlet of the geothermal heat pump unit body 1. The detachable filter assembly 3 is adapted to be installed inside the water inlet pipe 2. The straight-through housing 4 of the detachable filter assembly 3 includes a middle area housing 5 and a water outlet area housing 7. The middle area housing 5 is fitted with an anti-backflow kit 8. The water outlet area housing 7 is fitted with a spiral silicone tube 9. A one-way filter valve body 11 is fixedly installed inside the middle area housing 5.

[0037] The anti-backflow kit 8, through the elastic force of the conical spring 19, pushes the outer side of the umbrella-shaped rubber water-stop ring 20 against the inner wall of the inlet pipe 2. On the one hand, the umbrella-shaped structure can guide the water flow and prevent sewage from accumulating in the gap between the components. On the other hand, the elastic adaptation characteristics of the umbrella-shaped structure facilitate the quick snap-fit ​​between the components and the pipe, effectively improving the efficiency of disassembly and installation. At the same time, the spiral silicone tube 9 on the outer side of the housing 7 in the outlet area can further fill the gap between the housing and the inlet pipe 2, which not only enhances the sealing performance, but also forms a double fixing guarantee with the snap-fit ​​structure of the anti-backflow kit 8, ensuring the installation stability of the detachable filter component 3 in the pipe.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
