Description

Technical Field

[0001] The utility model relates to a water pump controller, and particularly to a compact water pump controller structure. Background Art

[0002] The existing structure of a booster pump, such as a booster pump in a Chinese utility model patent with the publication number CN206329503U, mainly includes a motor, a housing, and a suction chamber connected to the housing. An impeller is provided inside the housing, and the output shaft of the motor extends into the housing and is connected to the impeller. A pressure maintaining tank is also connected to the side wall of the suction chamber, and the inside of the pressure maintaining tank is in communication with the inside of the suction chamber.

[0003] The above-mentioned pressure maintaining tank can also be called a pneumatic tank. A booster pump pneumatic tank usually consists of a booster pump, a cylinder (or a tank body), a pressure gauge, a pressure switch, a safety valve, a pneumatic gauge, etc. Among them, the cylinder (or the tank body) is used to store compressed gas, and the booster pump is responsible for compressing the gas to the target pressure.

[0004] In order to improve the pressure maintaining effect of some booster pumps, an elastic bladder is installed in the pressure maintaining tank. The inside of the tank body in this part of the pressure maintaining tank is divided into a water chamber and a gas chamber. When the system pressure rises, water is compressed and enters the water chamber, and at the same time, the gas in the gas chamber is compressed; when the system pressure drops, the gas in the gas chamber is released and pushes the water into the system.

[0005] As shown in the attached drawings of the specification of a booster pump in a Chinese utility model patent with the publication number CN206329503U Figure 1 The pressure maintaining tank with the structure shown is connected to the suction chamber in a threaded connection form. The overall volume of the pressure maintaining tank with such a structure is relatively large, resulting in the volume of the entire booster pump not being effectively controlled. Content of the Utility Model

[0006] In view of this, the purpose of the utility model is to provide a compact water pump controller structure, which focuses on improving the pressure maintaining tank and its connection structure, so as to effectively control the volume of the entire water pump.

[0007] In order to solve the above technical problems, the technical solution of the utility model is as follows:

[0008] A compact water pump controller structure includes a controller main body and a valve body. An inlet, a communication channel, and an outlet are provided inside the controller main body, and the inlet, the communication channel, and the outlet are in communication with each other. The valve body is installed in the communication channel and is used to open and close the inlet;

[0009] A receiving groove is provided on the outer side wall of the controller main body, and the receiving groove is in communication with the communication channel;

[0010] It further includes an installation cover and an elastic capsule. The installation cover is installed at the notch of the accommodation groove facing away from the communication channel, and the elastic capsule is installed between the installation cover and the notch of the accommodation groove.

[0011] Through the above technical solution, the inherent structure on the outer side wall of the controller body is fully utilized to open the accommodation groove. Coupled with the structural form of the installation cover, the elastic capsule can undergo a certain deformation between the accommodation groove and the installation cover to achieve the pressure maintaining effect. The controller with the above structural form is structurally compact. After being installed on the corresponding water pump, the overall volume of the water pump is effectively controlled.

[0012] Preferably, the accommodation groove gradually becomes larger along the notch on the side away from the communication channel. The elastic capsule is recessed into the accommodation groove. A communication hole is provided at the bottom of the smallest end of the accommodation groove, and the accommodation groove communicates with the communication channel through the communication hole.

[0013] Through the above technical solution, the water flow enters the accommodation groove through the communication hole. The farther the accommodation groove is from the communication hole, the larger its notch is, increasing the sensitivity to the induced water flow pressure, and the deformation degree of the entire elastic capsule will also be greater.

[0014] Preferably, the elastic capsule includes a fastening edge and an induction layer. The fastening edge is located at the side position of the elastic capsule, and the fastening edge is clamped between the installation cover and the outer side wall of the controller body. The induction layer is located at the middle position of the elastic capsule, and the thickness of the induction layer is greater than the thickness of the fastening edge.

[0015] Through the above technical solution, the water flow impact force just entering the accommodation groove through the communication hole is relatively large. The anti-water flow impact performance of the induction layer with a larger thickness is enhanced, extending the actual service life of the elastic capsule. The fastening edge is clamped between the installation cover and the outer side wall of the controller body, with convenient installation and high installation stability.

[0016] Preferably, the induction layer is directly opposite to the communication hole.

[0017] Through the above technical solution, the water flow ejected from the communication hole can impact the induction layer immediately, greatly enhancing the deformation sensitivity of the entire elastic capsule.

[0018] Preferably, a deformation layer is provided between the induction layer and the fastening edge, and the thickness of the deformation layer gradually becomes thicker from the fastening edge to the induction layer.

[0019] Through the above technical solution, not only the anti-impact performance of the elastic capsule against the water flow ejected from the communication hole is enhanced, but also the deformation ability of the side wall of the elastic capsule gradually increases from the induction layer to the fastening edge, which is beneficial to ensuring the sensitivity of the elastic capsule to the water flow pressure.

[0020] Preferably, a groove is provided on the side wall of the induction layer close to the mounting cover, and the groove is directly opposite to the communication hole.

[0021] Through the above technical solution, the water flow ejected from the communication hole will impact the side wall of the induction layer corresponding to the groove for the first time. At this time, certain deformation is likely to occur on the side wall of the induction layer, thereby further improving the sensitivity of the entire elastic capsule to the water flow pressure.

[0022] Preferably, the mounting cover and the controller body are connected by bolts.

[0023] Through the above technical solution, by disassembling and assembling the bolts, the mounting cover and the controller body can be disassembled and assembled, and the disassembly and assembly convenience is high.

[0024] Preferably, a deformation groove is provided on the side wall of the mounting cover close to the elastic capsule.

[0025] Through the above technical solution, the deformation groove and the accommodation groove cooperate with each other, and the deformable space of the entire elastic capsule is greatly improved.

[0026] Preferably, a water pump is further included. The water pump includes a pump housing and a motor. A water outlet pipe is provided on the pump housing, and the water outlet pipe is connected to the water inlet. The controller body and the mounting cover are both located above the water pump, and the mounting cover and the motor face the same direction.

[0027] Through the above technical solution, on the one hand, the controller body is installed above the water pump, which fully improves the space utilization rate above the water pump; on the other hand, the mounting cover and the motor face the same direction, which is equivalent to making full use of the space above the motor, and the overall structural compactness is high.

Detailed implementation manners

[0034] A structure of a compact water pump controller, see Figure 1 and Figure 3 , including a controller main body 1 and a valve body 2.

[0035] Among them, a water inlet 3, a communication channel 4, and a water outlet 5 are provided in the controller main body 1, and the water inlet 3, the communication channel 4, and the water outlet 5 are interconnected. The valve body 2 is installed in the communication channel 4 and is used to open and close the water inlet 3.

[0036] A receiving groove 6 is provided on the outer side wall of the controller main body 1, and the receiving groove 6 communicates with the communication channel 4. It also includes a mounting cover 7 and an elastic bladder 9. The mounting cover 7 is installed at the notch of the receiving groove 6 facing away from the communication channel 4, and the elastic bladder 9 is installed between the mounting cover 7 and the notch of the receiving groove 6.

[0037] Among them, the receiving groove 6 gradually becomes larger along the notch on the side facing away from the communication channel 4, and the shape of the entire groove body of the receiving groove 6 is close to a frustum of a cone. A communication hole 13 is provided at the bottom of the smallest end of the receiving groove 6, and the receiving groove 6 communicates with the communication channel 4 through the communication hole 13.

[0038] The elastic bladder 9 includes a fastening edge 10, a deformation layer 11, and a sensing layer 12.

[0039] The fastening edge 10 is located at the side position of the elastic bladder 9, and the fastening edge 10 is clamped between the mounting cover 7 and the outer side wall of the controller main body 1.

[0040] The thickness of the deformation layer 11 gradually increases from the fastening edge 10 to the sensing layer 12.

[0041] The sensing layer 12 is located at the middle position of the elastic bladder 9, and the thickness of the sensing layer 12 is greater than the thickness of the fastening edge 10. The sensing layer 12 is directly opposite to the communication hole 13. A groove 14 is provided on the side wall of the sensing layer 12 close to the mounting cover 7, and the groove 14 is directly opposite to the communication hole 13.

[0042] The elastic bladder 9 is recessed into the receiving groove 6, and the shape formed by the entire sensing layer 12 and the deformation layer 11 is approximately the same as the groove shape of the receiving groove 6.

[0043] See Figure 1 and Figure 2 , in order to increase the disassembly and assembly convenience between the mounting cover 7 and the controller main body 1, the mounting cover 7 and the controller main body 1 are connected by bolts.

[0044] See Figure 2 and Figure 3 , a deformation groove 8 is provided on the side wall of the mounting cover 7 close to the elastic bladder 9. The deformation groove 8 cooperates with the receiving groove 6, and the deformation space of the elastic bladder 9 is effectively expanded.

[0045] See Figure 3 and Figure 4 , further comprising a water pump 15. The water pump 15 includes a pump housing 16 and a motor 17. A water outlet pipe 18 is provided on the pump housing 16. The water outlet pipe 18 is connected to the water inlet 3. The controller main body 1 and the mounting cover 7 are both located above the water pump 15, and the mounting cover 7 is in the same orientation as the motor 17.

[0046] During actual use, the valve body 2 opens the water inlet 3, and the water flow is divided into two directions for flowing. One is that the water flow sequentially passes through the water inlet 3 and the communication channel 4, and finally flows out from the water outlet 5;

[0047] The other is that the water flow sequentially passes through the water inlet 3, the communication channel 4, and the communication hole 13. The water flow ejected from the communication hole 13 impacts on the side wall of the sensing layer 12, and the deformation layer 11 deforms, and the entire elastic bladder 9 deforms in the receiving groove 6 and the deformation groove 8; when the water flow pressure becomes small, the elastic bladder 9 will squeeze the water originally located in the receiving groove 6 and the deformation groove 8 back into the communication channel 4 through the communication hole 13 again.

[0048] Of course, the above are only typical examples of the present invention. In addition, the present invention can also have many other specific implementation manners. Any technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection required by the present invention.
