Description

Technical Field

[0001] This utility model relates to the field of water pumps, and more particularly to a booster pump that is easy to inflate. Background Technology

[0002] Existing household booster pumps typically have a pressure tank installed on the outlet pipe, which helps ensure stable water flow. Since household booster pumps are used in homes or utility rooms near the entrance, a casing is often installed around the entire pump, with the pressure tank housed within it. The casing includes inlet, outlet, and other connection structures for easy connection to external piping. However, during use, various factors can lead to insufficient air in the pressure tank, requiring refilling. The significant distance between the pressure tank's inflation nozzle and the casing makes it difficult to directly insert an external inflation device's nozzle into the casing for inflation. This necessitates disassembling the booster pump from the piping, removing the casing, and exposing the pressure tank for inflation. This process is cumbersome, physically demanding, and prone to connection reliability issues and leaks during disassembly and reassembly. Summary of the Invention

[0003] The purpose of this invention is to solve the aforementioned problems in the existing technology by providing a booster pump that is easy to inflate. An inflation component is added to the pressure tank, extending the connection point for inflating the pressure tank to the casing. Without disassembling the casing, it can be easily connected to an external inflation device to inflate the pressure tank. This achieves the purpose of inflating the pressure tank (replenishing the pressure inside), is convenient to operate, and avoids disassembling the casing, thus improving inflation efficiency, reducing inflation workload, and preventing accidental damage to the casing or booster pump components during inflation. This reduces the cost of repairing accidental damage, protects the booster pump, and also reduces inflation costs.

[0004] The above-mentioned technical objective of this utility model is mainly achieved through the following technical solution: a booster pump that is easy to inflate, comprising a housing, a pump body assembly with a water outlet pipe section disposed within the housing, a pressure tank disposed on the pump body assembly, the pressure tank cooperating with the water outlet pipe section to stabilize the water outlet pressure, and an inflation nozzle disposed on the pressure tank for replenishing air into the pressure tank, characterized in that an inflation port is opened on the housing, an inflation assembly is connected to the inflation nozzle, the inflation end of the inflation assembly extends to the inflation port, and the inflation end or an external inflation device passes through the inflation port to connect the inflation end with the external inflation device for replenishing air into the pressure tank. By adding an inflation component to the pressure tank, the connection point for inflation extends to the housing. This allows for easy connection to external inflation equipment without disassembling the housing, achieving the purpose of inflating the pressure tank (replenishing the internal pressure). This is convenient to operate, avoids disassembling the housing, improves inflation efficiency, reduces inflation workload, and prevents accidental damage to the housing or booster pump during inflation. This also reduces the cost of repairing accidental damage, protects the booster pump, and lowers inflation costs.

[0005] As a further improvement and supplement to the above technical solution, the present invention adopts the following technical measures:

[0006] Preferably, the inflation assembly includes a connecting pipe and a valve stem disposed within the connecting pipe. The inner end of the connecting pipe engages with the inflation nozzle, and the inner end of the valve stem also engages with the inflation nozzle. During inflation, the outer end of the valve stem receives a thrust toward the pressure tank, causing the valve stem to move and open the inflation nozzle. When not inflating, the valve stem returns to its original position, and the inflation nozzle closes due to the loss of valve stem function. The cavity between the connecting pipe and the valve stem is a vented and connected cavity. When the inflation nozzle is open, the inner end of the cavity connects to the inner end of the pressure tank, and the outer end of the cavity connects to the inner cavity of the connector on an external inflation device, allowing the external inflation device to supply air to the cavity, which then enters the pressure tank for inflation.

[0007] Preferably, the inflation assembly further includes a make-up air valve located at the inflation end of the connecting pipe. The outer end of the valve stem engages with the make-up air valve, which is used to connect with an external inflation device. The purpose of the make-up air valve is to ensure that during inflation, gas can only flow into the pressure tank, preventing gas from flowing out and thus ensuring the reliability and effectiveness of inflation.

[0008] Preferably, the air filling valve nozzle is provided with a first one-way valve core, and the air filling nozzle is provided with a second one-way valve core. The first one-way valve core engages with the outer end of the valve stem, and the second one-way valve core engages with the inner end of the valve stem. When the first one-way valve core is open, it pushes the valve stem toward the pressure tank to open the second one-way valve core, thus opening the air filling nozzle for air filling. Conversely, the first one-way valve core, the valve stem, and the second one-way valve core are reset. The arrangement of the first and second one-way valve cores forms two leak-proof measures (i.e., gas flowing out of the pressure tank), and ensures the reliability and effectiveness of filling the pressure tank.

[0009] Preferably, the first one-way valve core or the valve stem has an axial limiting structure between itself and the connecting pipe. The axial limiting structure is used to limit the axial displacement of the valve stem, avoid excessive movement of the first one-way valve core and the second one-way valve core, and help protect the sensitivity and reliability of the first one-way valve core and the second one-way valve core. This helps prevent the pressure tank from leaking air through the failed first one-way valve core and the second one-way valve core.

[0010] Preferably, a reset assembly is provided between the valve stem and the connecting pipe or the first one-way valve core. The reset assembly is used to reset the valve stem and close the second one-way valve core.

[0011] Preferably, the cavity between the connecting pipe and the valve stem is an inflation cavity. When the first one-way valve in the air supply valve on the inflation assembly and the second one-way valve in the inflation nozzle are opened, the outer end of the inflation cavity is connected to an external inflation device, and the inner end of the inflation cavity is connected to the inner cavity of the pressure tank.

[0012] Preferably, the air supply valve is located inside the housing or its outer end is flush with the inner wall of the housing. Specifically, the distance between the outer end of the air supply valve and the inner wall of the housing is d, where d ranges from 0 to 20 mm. In other words, the outer end of the air supply valve does not extend beyond the housing, which helps protect the valve and prevents damage from external factors (such as accidental collisions, impacts, or scraping). Simultaneously, the outer end of the air supply valve is close to the housing, facilitating connection with external inflation equipment.

[0013] Preferably, the housing is provided with an openable cover, which cooperates with the inflation port to either cover the inflation port or expose it. The cover helps to further protect the air supply valve nozzle, prevents foreign objects from entering the housing, and ensures the normal and stable operation of the internal mechanisms.

[0014] Preferably, the connection point of the connecting tube on the inflation assembly is airtightly fitted with the wall of the inflation nozzle. This helps prevent air leakage and improves inflation efficiency.

[0015] The beneficial effects of this utility model are as follows: 1. By adding an inflation component to the pressure tank, the connection part for inflation extends to the cover. Without disassembling the cover, it is easy to connect with external inflation equipment to inflate the pressure tank, achieving the purpose of inflating the pressure tank (replenishing the internal pressure), facilitating operation, and avoiding disassembly of the cover. This improves inflation efficiency, reduces inflation workload, and prevents accidental damage to the cover or booster pump during inflation, thus reducing repair costs. It also protects the booster pump and reduces inflation costs. 2. The installation of a first and second one-way valve core that open or close in the same direction ensures smooth inflation and provides double pressure maintenance inside the pressure tank (i.e., double pressure maintenance at the replenishment valve or inflation nozzle). This helps prevent pressure tank leakage due to damage to the first or second one-way valve core, ensuring the stability of the internal pressure of the pressure tank. 3. The outer end of the air replenishment valve is located inside the housing and close to the housing. This facilitates connection with external inflation equipment for inflation and also helps protect the air replenishment valve from damage caused by external factors. Attached Figure Description

[0019] The technical solution of this utility model will be further described in detail below through embodiments and with reference to the accompanying drawings. In this document, the end of the connecting tube that is connected to the external inflation device is the outer end, that is, the direction corresponding to the "outer" side, and vice versa, it is the inner end, that is, the direction corresponding to the "inner" side.

[0020] Example: Figure 1 and Figure 2As shown, a booster pump that is easy to inflate includes a housing 1, a pump body assembly with a water outlet pipe section 2 disposed inside the housing 1, a motor that drives the impeller assembly inside the pump body assembly, a pressure tank 4 provided on the pump body assembly, the pressure tank 4 cooperating with the water outlet pipe section 2 to stabilize the water outlet pressure, and an air inlet 5 provided on the pressure tank 4 for replenishing air into the pressure tank 4.

[0021] In this technical solution, the housing 1 is further provided with an inlet and an outlet, and the pump body assembly is provided with an inlet pipe section 3. The inlet pipe section 3 cooperates with the inlet, and the outlet pipe section 2 cooperates with the outlet.

[0022] The difference between this technical solution and the prior art is that: an air inlet 6 is opened on the upper part of the cover 1, an air inlet assembly is connected to the air inlet 5, the air inlet end of the air inlet assembly extends to the air inlet 6, and the air inlet end or external air inlet device passes through the air inlet 6 to connect the air inlet end with the external air inlet device for replenishing the pressure tank 4 with air.

[0023] In this technical solution, an inflation component is added to the pressure tank 4, extending the connection for inflation of the pressure tank 4 to the cover 1. Without disassembling the cover 1, it is easy to connect with an external inflation device to inflate the pressure tank 4. This achieves the purpose of inflating the pressure tank 4 (replenishing the air pressure inside the pressure tank 4), facilitates operation, and avoids disassembling the cover 1. This improves inflation efficiency, reduces inflation workload, and prevents accidental damage to the cover 1 or other parts or components of the booster pump during inflation. This reduces the cost of repairing accidental damage, protects the booster pump, and reduces inflation costs.

[0024] The above technical solution will then be explained in detail:

[0025] In practical applications, the inflation assembly includes a connecting pipe 7 and a valve stem 8 disposed within the connecting pipe 7. The inner end of the connecting pipe 7 engages with the inflation nozzle 5, and the inner end of the valve stem 8 also engages with the inflation nozzle 5. During inflation, the outer end of the valve stem 8 receives a thrust towards the pressure tank 4, causing the valve stem 8 to move and open the inflation nozzle 5. When not inflating, the valve stem 8 returns to its original position, and the inflation nozzle 5 closes due to the loss of the valve stem 8's influence. The cavity between the connecting pipe 7 and the valve stem 8 is a ventilated and interconnected cavity. When the inflation nozzle 5 is open, the inner end of the cavity connects to the inner end of the pressure tank 4, and the outer end of the cavity connects to the inner cavity of the connector on an external inflation device, allowing the external inflation device to supply air to the cavity, which then enters the pressure tank 4 for inflation.

[0026] In practical applications, the inflation assembly also includes an air replenishment valve 9 located at the inflation end of the connecting pipe 7. The outer end of the valve stem 8 cooperates with the air replenishment valve 9, and the air replenishment valve 9 is used to form a connection with an external inflation device.

[0027] In this technical solution, the purpose of setting the air filling valve 9 is to ensure that during inflation, gas can only flow into the pressure tank 4, preventing the gas in the pressure tank 4 from flowing out, which helps to ensure the reliability and effectiveness of inflation of the pressure tank 4.

[0028] In practical applications, the air filling valve 9 is equipped with a first one-way valve core, and the air filling nozzle 5 is equipped with a second one-way valve core. The first one-way valve core engages with the outer end of the valve stem 8, and the second one-way valve core engages with the inner end of the valve stem 8. When the first one-way valve core is open, it pushes the valve stem 8 towards the pressure tank 4 to push open the second one-way valve core, thus opening the air filling nozzle 5 for inflation. Conversely, the first one-way valve core, the valve stem 8, and the second one-way valve core are reset. The arrangement of the first and second one-way valve cores forms two leak-proof measures (i.e., gas flowing out of the pressure tank 4), ensuring the reliability and effectiveness of inflation of the pressure tank 4.

[0029] In other words, when the external inflation device connects to the air filling valve 9 for inflation, the first one-way valve opens and pushes towards the inner cavity of the pressure tank 4. The first one-way valve causes the valve stem 8 to move towards the inflation nozzle 5, and the valve stem 8 in turn causes the second one-way valve core to move towards the inner cavity of the inflation tank, thereby opening the inflation nozzle 5. This allows the air passage (the air outlet on the external inflation device, the wall between the connecting pipe 7 and the valve stem 8, the inflation nozzle 5, and the inner cavity of the pressure tank 4) to be connected for inflation.

[0030] In practical applications, the first one-way valve core or the valve stem 8 has an axial limiting structure between it and the connecting pipe 7.

[0031] In this technical solution, the axial limiting structure is used to restrict the axial displacement of the valve stem 8, preventing excessive movement of the first and second one-way valve cores. This helps protect the sensitivity and reliability of the first and second one-way valve cores, thereby preventing air leakage from the pressure tank 4 through the failed first and second one-way valve cores. The axial limiting structure has various forms in the prior art, and is a conventional technology that is easily conceived by those skilled in the art. To avoid redundancy, a detailed description of the axial limiting structure is omitted.

[0032] In practical applications, a reset assembly is provided between the valve stem 8 and the connecting pipe 7 or the first one-way valve core. The reset assembly is used to reset the valve stem 8, thereby closing the second one-way valve core. The specific structure of the reset assembly has various forms in the prior art, and is a conventional technology that is readily conceived by those skilled in the art. To avoid redundancy, a detailed description of the reset assembly is omitted.

[0033] In practical applications, the cavity between the connecting pipe 7 and the valve stem 8 is the inflation chamber 12. When the first one-way valve in the air supply valve 9 on the inflation assembly and the second one-way valve in the inflation nozzle 5 are opened, the outer end of the inflation chamber 12 is connected to the external inflation equipment, and the inner end of the inflation chamber 12 is connected to the inner cavity of the pressure tank 4.

[0034] In practical applications, the air supply valve 9 is located inside the housing 1 or the outer end of the air supply valve 9 is flush with the inner wall of the housing 1. That is, the distance between the outer end of the air supply valve 9 and the inner wall of the housing 1 is d, and the value of d ranges from 0 to 20 mm.

[0035] In this technical solution, the outer end of the air supply valve nozzle 9 does not extend to the outside of the housing 1, which helps to protect the air supply valve nozzle 9 and prevents the extended part from being damaged by external factors (such as accidental collisions, impacts, hooks, etc.). At the same time, the outer end of the air supply valve nozzle 9 is very close to the housing 1, which facilitates connection with external inflation equipment.

[0036] In practical applications, the cover 1 is provided with an openable cover 13, which cooperates with the air inlet 6 to cover the air inlet 6 or expose the air inlet 6.

[0037] In this technical solution, the cover 13 is designed to further protect the air supply valve 9, prevent foreign objects from entering the housing 1, and ensure the normal and stable operation of the various mechanisms inside the housing 1.

[0038] In practical applications, to prevent air leakage and improve inflation efficiency, the connection part of the connecting pipe 7 and the wall of the inflation nozzle 5 are airtightly fitted. The specific structure of this airtight fit has various forms in the prior art (such as setting a sealing ring between the connection part of the connecting pipe 7 and the wall of the inflation nozzle 5), which is a conventional technique and a technical solution easily conceived by those skilled in the art. To avoid redundancy, a detailed description of the airtight fit structure is omitted.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Various modifications and variations can be made to the above embodiments. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
