[0001] This utility model relates to the field of booster pump technology, specifically to a novel booster pump. Background Technology

[0002] A booster pump is a device that converts mechanical energy into fluid pressure energy. It is mainly used to increase the pressure of fluids (liquids or gases) to meet the needs of transportation or specific working conditions. Booster pumps contain a piston assembly, which experiences significant pressure drop during water pressurization, making it difficult to meet the requirements of cleaning products such as dental irrigators that require booster pumps with low flow rates and high pressures. Utility Model Content

[0003] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a new type of booster pump. By installing an elastic component on the piston assembly, it can assist the piston assembly in draining water and compensate for the reduced pressure during the piston assembly's water pressing process.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a novel booster pump, comprising a pump body, a drive component, a piston assembly, and an elastic cavity. One end of the pump body has an outlet and an inlet. The elastic cavity is installed inside the outlet. The drive component is installed inside the pump body at the end away from the outlet. The piston assembly is located between the drive component and the elastic cavity and is connected to the drive component for transmission. The piston assembly is used to compress the elastic cavity, and an elastic component is installed on the piston assembly. The end of the elastic component near the drive component is fixed inside the pump body.

[0005] Furthermore, the driving component includes a power component and a transmission component. The power component is fixed in the pump body, and one end of the transmission component is fixedly connected to the output end of the power component, while the other end is connected to the piston assembly for transmission.

[0006] Furthermore, the power component is an electric motor.

[0007] Furthermore, the transmission component includes a main gear and a transmission gear. The main gear is fixedly connected to the output end of the motor, and the transmission gear is rotatably connected to the pump body and meshes with the main gear. An eccentric component is fixed on the transmission gear, and the eccentric component is connected to the piston assembly in a transmission connection.

[0008] Furthermore, the number of teeth on the main gear is much smaller than the number of teeth on the transmission gear.

[0009] Furthermore, the eccentric component is an eccentric block; The piston assembly includes a piston rubber head, a piston rod, and a mounting sleeve. The piston rubber head and the mounting sleeve are respectively fixed to both ends of the piston rod, and the piston rubber head is located on one side of the elastic cavity.

[0010] Furthermore, the elastic cavity is an elastic tubing.

[0011] Furthermore, the elastic component includes a limiting plate and a spring. The limiting plate is fixed in the pump body, and the spring is sleeved on the piston rod, with one end of the spring near the mounting sleeve being fixedly connected to the limiting plate.

[0012] Furthermore, the limiting plate is U-shaped.

[0013] Furthermore, the spring is a tower-shaped spring. After adopting the above technical solution, the beneficial effects of this utility model are as follows: When the booster pump draws water, the drive component pulls the piston assembly to compress the elastic component, which then stores energy.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0019] This embodiment relates to a novel booster pump, such as... Figure 1-2 As shown, the pump includes: a pump body 1, a drive component, a piston assembly, and an elastic cavity. One end of the pump body 1 has an outlet 8 and an inlet 7. The elastic cavity is installed inside the outlet 8. The drive component is installed inside the pump body 1 at the end furthest from the outlet 8. The piston assembly 6 is located between the drive component and the elastic cavity and is connected to the drive component for transmission. The piston assembly 6 is used to compress the elastic cavity, and a spring component 5 is installed on the piston assembly 6. The end of the spring component 5 near the drive component is fixed inside the pump body 1. When the booster pump is working, the drive component drives the piston assembly to reciprocate within the pump body 1. During this process, the pump body 1 is under negative pressure, causing external water to be forced into the pump body 1 through the inlet 7, i.e., the pump body 1 draws in water. Simultaneously, the drive component pulls the piston assembly 6 to compress the spring component 5, causing the spring component 5 to store energy. After the pump body 1 is filled with water, the drive component pushes the piston assembly 6 to move within the pump body 1, compressing the elastic cavity and causing the water inside the pump body 1 to be discharged. During the drainage process, the piston assembly 6 is not only subjected to the thrust of the driving component, but also to the elastic force of the elastic component 5, which helps the piston assembly 6 to move. This effectively solves the problem of large pressure drop during the piston push rod water pressing process of existing booster pumps, and can meet the requirements of cleaning products such as dental flossers for booster pumps with small flow and high pressure.

[0020] like Figure 2 As shown, the driving component includes a power component and a transmission component 3. The power component is fixed inside the pump body 1. One end of the transmission component 3 is fixedly connected to the output end of the power component, and the other end is connected to the piston assembly 6. The power component is used to output power. Specifically, the power component is a motor 2, and the motor 2 drives the piston assembly 6 to move through the transmission component 3.

[0021] like Figure 2 As shown, the transmission component 3 includes a main gear 31 and a transmission gear 32. The main gear 31 is fixedly connected to the output end of the motor 2, and an eccentric component is fixed on the transmission gear 32. The eccentric component is connected to the piston assembly 6 in a transmission manner, and the eccentric component drives the piston assembly 6 to make eccentric movements on the transmission gear 32.

[0022] Furthermore, the number of teeth on the main gear 31 is much smaller than the number of teeth on the transmission gear 32. The transmission gear 32 is rotatably connected to the pump body 1 and meshes with the main gear 31, which facilitates the conversion of the high-speed main gear 31 into the low-speed transmission gear 32. At the same time, the transmission gear 32 receives more torque, thereby driving the piston assembly 6 to decelerate and achieve low-frequency operation and small flow output of the booster pump.

[0023] Furthermore, the eccentric component is an eccentric block 321; the piston assembly 6 includes a piston rubber head 61, a piston rod 62 and a mounting sleeve 63. The piston rubber head 61 and the mounting sleeve 63 are respectively fixed to both ends of the piston rod 62, and the piston rubber head 61 is located on one side of the elastic cavity. The mounting sleeve 63 is connected to the eccentric block 321 in a transmission manner, and the elastic component 5 is installed on the piston rod 62.

[0024] like Figure 2 As shown, the elastic cavity is an elastic tubing 4.

[0025] like Figure 2 As shown, the elastic component 5 includes a limiting plate 51 and a spring 52. The limiting plate 51 is fixed inside the pump body 1, and the spring 52 is sleeved on the piston rod 62. One end of the spring 52 near the mounting sleeve 63 is fixedly connected to the limiting plate 51. The limiting plate 51 plays a role in fixing and limiting the spring 52. When the piston rod 62 reciprocates, it will drive the spring 52 to perform compression or extension movements on the limiting plate 51, thereby realizing the storage of force by the spring 52 and the assistance to the piston rod 62.

[0026] Specifically, the limiting plate 51 is U-shaped, which not only facilitates the installation of the piston rod 62 inside the limiting plate 51 and the subsequent movement of the piston rod 62 inside the limiting plate 51, but also facilitates the fixing of the spring 52.

[0027] Specifically, spring 52 is a tower spring. Tower springs have better energy absorption, are softer in the initial stage (small diameter section), and have stronger support force in the later stage (large diameter section), making them suitable for impact load buffering; they have stronger spatial adaptability and can provide greater deformation capacity within a limited stroke; they have more uniform stress distribution, reducing the risk of wear in local high stress areas and extending service life.

[0028] The working principle of this utility model is roughly as follows: When the booster pump is in use, the motor 2 is started, and the motor 2 drives the main gear 31 to move at high speed. The main gear 31 drives the transmission gear 32 to rotate. Since the number of teeth of the main gear 31 is much less than the number of teeth of the transmission gear 32, the transmission gear 32 can convert high speed into low speed. At the same time, the transmission gear 32 obtains more torque. The transmission gear 32 will drive the eccentric block 321 to rotate. In turn, the eccentric block 321 drives the piston assembly 6 to perform deceleration and eccentric reciprocating motion in the pump body 1. The booster pump realizes low frequency operation and small flow output. During the reciprocating motion of piston assembly 6, the pump body 1 will be under negative pressure. Transmission component 3 first pulls piston assembly 6, so that external water is forced into pump body 1 through water inlet 7, that is, pump body 1 draws water. At the same time, piston rubber head 61 in piston assembly 6 will compress spring 52 on piston rod 62, so that spring 52 stores force. Then, the transmission component 3 pushes the piston assembly 6 to perform the drainage action. The piston assembly 6 squeezes the hose 4 inside the pump body 1, making the receiving cavity inside the hose 4 smaller, and draining the water in the pump body 1 to the outlet 8. During the drainage process, the piston assembly 6 is not only pushed by the driving component, but also by the elastic force of the spring 52, which helps the piston assembly 6 move. This effectively solves the problem of large pressure drop in existing booster pumps during the piston push rod water pressure process, and can meet the requirements of cleaning products such as dental flossers for booster pumps with small flow and high pressure.

Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
