Description

Technical Field

[0001] This disclosure relates to a pump. More specifically, this disclosure relates to a submersible pump and a handle associated with the pump. Background Technology

[0002] A pump, such as a submersible pump (or auxiliary pump or electric submersible pump), is a device that can be submerged in the fluid medium to be pumped. Submersible pumps are typically used in various applications, such as clean water operations and wastewater operations. These applications may require adjusting the pump's height, transporting the pump from one location to another, and so on.

[0003] Some pumps may include a height adjustment mechanism that allows for adjustment of the pump's height. However, this height adjustment mechanism is complex in design and includes multiple parts that move relative to each other. It also includes multiple contact surfaces associated with the movable parts. Furthermore, dirt particles present in the pumped fluid may become trapped between the movable parts. In some cases, dirt particles may clog one or more parts of the height adjustment mechanism, which can in turn affect the operation of the submersible pump.

[0004] Furthermore, traditional submersible pumps include a handle that allows the pump to be transported from one location to another. The handle acts as a "trigger" to allow for changes in pump position. Current designs of the handles associated with pumps may expose multiple parts of the handle, allowing foreign particles to enter. Additionally, such handles can make cleaning and other maintenance difficult. Therefore, there is a need for an improved handle design for submersible pumps that is user-friendly and ergonomic. Furthermore, it is desirable that the handle be easy to clean and maintain.

[0005] CN Utility Model Patent Application No. 21,0961,650 (hereinafter referred to as '650 Reference) describes a low-noise food processor. This low-noise food processor includes a handle, a handle flip cover, and a limiting groove. The handle flip cover and the side wall of the machine housing are directly and detachably connected, allowing the user to remove the handle flip cover. Furthermore, the handle flip cover is hinged to the side wall via a hinge axis around the bottom of the handle flip cover. However, the handle described in '650 Reference is associated with the food processor. Moreover, this arrangement of the handle flip cover and the handle is complex and may make the handle susceptible to intrusion of foreign particles.

[0006] CN Utility Model Application No. 204,226,273 (hereinafter referred to as '273 Reference) discloses a telescopic handle structure for a small submersible pump. This telescopic handle structure includes a pump body and a handle. A connecting portion perpendicular to a horizontal base plane is disposed on the outer surface of the pump body. Furthermore, the handle is movably connected to the connecting portion in a telescopic manner. The connecting portions are symmetrically distributed on guide flange portions on both sides of the outer surface of the pump body. Additionally, limiting grooves are provided on each of the left and right sides of each guide flange portion. The telescopic handle structure of '273 Reference appears to include a two-part handle structure, which looks bulky, inconvenient, and space-constrained, potentially limiting access between the handle and the guide flange portions, among other implementation drawbacks. Summary of the Invention

[0007] In view of the above, the object of this disclosure is to solve or at least reduce the aforementioned disadvantages. This object is achieved at least in part by a novel design for a handle for a pump. The pump includes a pump body. The pump also includes a handle coupled to the pump body. The handle includes a first portion defining a top element and a bottom element. The handle also includes a second portion defining a base element. The base element of the second portion at least partially covers the top element of the first portion, or the top element of the first portion at least partially covers the base element of the second portion. Furthermore, the first and second portions are movable relative to each other. The pump is characterized in that the first portion is coupled to the second portion such that the top element of the first portion can be removed from the first portion.

[0008] The handle disclosed herein features a user-friendly and ergonomic design, making the pump handle easy to clean and maintain. The handle described herein also reduces any gaps between the movable parts of the handle (i.e., the first or second part) exposed to fluid. This feature, in turn, reduces any risk of blockage of the movable parts due to foreign particles. Furthermore, the top element can be easily attached / removed to allow easy access for cleaning the handle portion, which in this context refers to the bottom element and the second part.

[0009] According to an embodiment of this disclosure, removal of the top element of the first portion allows access to the base element of the second portion.

[0010] This feature makes the handle portion (i.e., the base element of the second part) easily accessible for cleaning, so as to remove any obstructions or foreign objects from the movable part of the handle.

[0011] According to embodiments of this disclosure, the first and second portions are removably connected by one or more of screws, snap-fit ​​mechanisms, and pins. This connection technique allows for quick attachment and separation of the first and second portions.

[0012] According to embodiments of this disclosure, the handle defines a left arm and a right arm. A top element of the first portion is removably attached to one or more of the left and right arms. This feature allows for easy and quick removal of the top element to access the base element without the need for additional tools.

[0013] According to embodiments of this disclosure, the left and right arms of the handle are at least partially engaged with the pump's mechanism. This provides a robust setup for the pump's handle and mechanism, and also helps simplify the technology of the movable basket of the triggering mechanism.

[0014] According to an embodiment of this disclosure, the pump also includes a movable basket that can move between a first position and a second position. Actuation of a first portion of the handle biases the movable basket into one of the first and second positions. This feature allows for simple and user-friendly operation for switching the movable basket between the first and second positions. Furthermore, this feature allows the pump to be used in different modes, such as a clean water mode and a wastewater mode.

[0015] According to an embodiment of this disclosure, the mechanism includes a movable basket. The movable basket allows the pump to be used in different applications and modes.

[0016] According to embodiments of this disclosure, the pump is a submersible pump. The submersible pump is used in both clean water and dirty water modes; however, the pump can be any pump used or known in the art.

[0017] Other features and aspects of this disclosure will become apparent from the following description and accompanying drawings. Attached Figure Description

[0025] The present disclosure will be described more fully below with reference to the accompanying drawings, which illustrate exemplary embodiments of the present disclosure incorporating one or more aspects thereof. However, the present disclosure may be embodied in many different forms and should not be construed as limiting itself to the embodiments set forth herein; rather, these embodiments are provided so that the disclosure will be comprehensive and complete, and will fully convey the scope of the disclosure to those skilled in the art. For example, one or more aspects of the present disclosure may be used in other embodiments and even in other types of structures and / or methods. In the drawings, the same numerals denote the same elements.

[0026] The use of certain terms in this document is for convenience only and should not be construed as a limitation of this disclosure. For example, terms such as “upper,” “lower,” “front,” “rear,” “side,” “longitudinal,” “lateral,” “transverse,” “upward,” “downward,” “forward,” “backward,” “towards,” “left,” “right,” “horizontal,” “vertical,” “above,” “inner,” “outer,” “inward,” “outward,” “top,” “bottom,” “higher,” “above,” “below,” “center,” “middle,” “between,” “end,” “adjacent,” “near,” “far,” “remote,” “radial,” and “circumferential” describe only the configurations shown in the figures. In fact, components can be oriented in any direction, and therefore, unless otherwise specified, the terms should be understood to include such variations.

[0027] Figure 1 A perspective view of pump 100 is shown. This disclosure relates to pump 100. Pump 100 is a submersible pump 100. However, this disclosure can be readily implemented with any pump used or known in the art. Pump 100 can be used for a variety of fluid handling operations to pump fluids. The fluid may include water or any other fluid with different viscosities. In one example, pump 100 may include a multistage centrifugal pump operating in a vertical position.

[0028] Pump 100 includes a pump housing 102. The pump housing 102 is generally hollow and houses multiple components of the pump 100 within it. Pump 100 includes a prime mover (not shown) disposed within the pump housing 102. The prime mover generates operating power and may include a tightly sealed motor (not shown). Pump housing 102 has an inlet 104 and an outlet 106 for fluid. Fluid is pumped in through inlet 104 and pumped out through outlet 106. Outlet 106 connects to a hose connector 108, which allows connection of a hose (not shown) for pumping the fluid. Pump 100 may also include other components (not shown), such as an impeller, shaft, bearings, etc.

[0029] like Figure 2 As shown, pump 100 includes mechanism 110. Furthermore, mechanism 110 includes a movable basket 112. Movable basket 112 is adapted to move between a first position "P1" (not shown) and a second position "P2", as shown in the figures. Mechanism 110 allows movable basket 112 to switch between the first position "P1" and the second position "P2". The first position "P1" is the extended position of movable basket 112. Furthermore, the second position "P2" is the retracted position of movable basket 112. The first position "P1" and the second position "P2" of movable basket 112 provide necessary variations in the inlet area of ​​inlet 104. Furthermore, the first position "P1" and the second position "P2" adjust the inlet 104 of pump 100 to allow pump 100 to operate in dirty water mode and clean water mode. More specifically, the first position "P1" and the second position "P2" of movable basket 112 correspond to dirty water mode and clean water mode, respectively. Since the dirty water mode requires a larger inlet area to ensure the effective operation of pump 100 compared to the clean water mode, the movable basket 112 is moved to the first position "P1" for operating pump 100 in dirty water mode.

[0030] Operation of pump 100 in the first position "P1" allows for the treatment of dirty water, where dirt particles of varying sizes can enter without obstruction. To switch to the first position "P1", the movable basket 112 moves relative to the pump housing 102 within the pump housing 102. Moving the movable basket 112 to the first position "P1" increases the overall height of pump 100.

[0031] The first position “P1” of the movable basket 112 allows one or more inlet openings (not shown) disposed on the movable basket 112 to be exposed. The inlet openings are positioned adjacent to inlet 104. In one example, pump 100 may include a plurality of inverted “U”-shaped inlet openings. However, the inlet openings may have any other shape, size, number, and size without any limitation. The first position “P1” and the second position “P2” of the movable basket 112 allow pump 100 to be configured for different applications based on the desired size of the inlet openings, depending on the switching of the movable basket 112 between the first position “P1” and the second position “P2”.

[0032] Furthermore, operation of pump 100 in the second position "P2" allows for the treatment of clean water. In the second position "P2", clean water can enter pump 100 from inlet 104. The second position "P2" of movable basket 112 restricts the flow of any large particles. To switch to the second position "P2", movable basket 112 moves relative to pump housing 102 within pump housing 102. Moving movable basket 112 to the second position "P2" reduces the overall height of pump 100. Additionally, in the second position "P2" of movable basket 112, the inlet opening is partially or completely covered by pump housing 102 depending on application requirements.

[0033] Although this disclosure specifies two positions, namely a first position "P1" and a second position "P2", a practical implementation of this disclosure may have multiple positions between the first position "P1" and the second position "P2" of the movable basket 112. More specifically, the movable basket 112 may take any other position between the first position "P1" and the second position "P2". Furthermore, multiple positions may then allow for multiple operating modes of the pump 100.

[0034] In addition, pump 100 includes a pump body 114. Pump body 114 or mechanism 110 may include any technology, means, or components that allow the movable basket 112 to move and be actuated between a first position "P1" and a second position "P2". Pump 100 also includes a handle 116 adapted to be coupled to pump body 114. In some embodiments, handle 116 may be adapted to be coupled to housing 114 or any other part of pump 100 without limiting this disclosure. Handle 116 allows a user to move pump 100. Furthermore, handle 116 serves as a "trigger" for switching the movable basket 112 between the first position "P1" and the second position "P2". Handle 116 includes defining a top element 120 and a bottom element 122 (in... Figure 5The first portion 118 (best shown in the diagram) is further actuated to bias the movable basket 112 into one of a first position "P1" and a second position "P2". The first portion 118 serves as an actuator for changing the position of the movable basket 112. Furthermore, the first portion 118 of the handle 116 can be actuated based on touch, pressing, pressing and holding, etc. In some embodiments, the handle 116 may include additional components or combinations of components to achieve the intended function of actuating or triggering movement of the movable basket 112.

[0035] This disclosure relates to top element 120. Top element 120 will now be explained in detail. Figure 3 A perspective view of the top element 120 of the first portion 118 is shown. It should be noted that the shape of the top element 120 generally corresponds to that of the adjacent bottom element 122 (see...). Figure 2 The upper part 123 (see) Figure 2 The top element 120 includes a "C"-shaped design. However, depending on the design of the handle 116, the top element 120 of the first portion 118 may have a shape that allows the top element 120 to cover the base element 124 (see...). Figure 4 , 5 And 6) any shape and size.

[0036] The top element 120 may be made of materials such as plastic, metal, or wood. The top element 120 defines a first end 126 and a second end 128. The top element 120 defines an inner surface 129 and an outer surface 131 opposite to the inner surface 129. Furthermore, the top element 120 includes a first hole 130 defined at the first end 126 and a second hole 132 defined at the second end 128. The first hole 130 and the second hole 132 are aligned. In the illustrated embodiment, the first hole 130 and the second hole 132 are circular in shape. Alternatively, the first hole 130 and the second hole 132 may have a square shape, a rectangular shape, an elliptical shape, etc. It should be noted that the top element 120 may include any number of holes having various shapes and sizes without limiting the scope of this disclosure. In the illustrated example, the first hole 130 and the second hole 132 are implemented as through holes. In some embodiments, the top element 120 may include a pair of protrusions, grooves, or any other connecting elements projecting from the outer surface 131 or inner surface 129 of the top element 120 to engage with corresponding mating elements on the bottom element 122.

[0037] Furthermore, the top element 120 includes a pair of sides 134, of which only one is shown herein. In some instances, the pair of sides 134 may be parallel to each other. In other instances, each side 134 may be angled such that the pair of sides 134 are not parallel to each other. Additionally, the top element 120 defines an opening 135 to receive the bottom element 122 when the top element 120 is coupled to the bottom element 122 and the base element 124. Furthermore, the length “L” defined by the top element 120 may be substantially equal to or slightly greater than the distance between the left arm 136 and the right arm 138.

[0038] like Figure 2 As shown, handle 116 defines a left arm 136 and a right arm 138, wherein a top element 120 of the first portion 118 is removably coupled (or click-fitted) to one or more of the left arm 136 and the right arm 138. The left arm 136 and the right arm 138 form part of a bottom element 122. The bottom element 122 includes a generally inverted "U"-shaped design. In some embodiments, the bottom element 122 is designed to resemble a bridge between the left arm 136 and the right arm 138. This allows for easy and stable coupling of the bottom element 122 to the top element 120. The material of the bottom element 122 may include plastic, metal, wood, etc. In some embodiments, removing the top element 120 may allow for the assembly or disassembly of different parts or components of the mechanism 110 or the pump 100. More specifically, removing the top element 120 may allow for the assembly or disassembly of the left arm 136 and the right arm 138 or any other part of the handle 116. Therefore, this simple and easy-to-remove setup of the top element 120 allows for efficient and user-friendly on-site cleaning, or even cleaning after removing parts or components from the handle 116.

[0039] The left arm 136 and right arm 138 of the bottom element 122 extend downward toward the inlet 104 of the pump 100. The left arm 136 and right arm 138 of the handle 116 are adapted to engage at least partially with the mechanism 110 of the pump 100. The engagement of the left arm 136 and right arm 138 with the mechanism 110 allows the movable basket 112 to switch between a first position “P1” and a second position “P2” based on the actuation of the first portion 118 of the handle 116.

[0040] The bottom element 122 of the first part 118 includes a first engagement element 140 (such as...). Figure 5 (as shown) and the second bonding element 142 (as shown) Figure 2 (As shown). A first engaging element 140 is disposed on the left arm 136, while a second engaging element 142 is disposed on the right arm 138. Furthermore, the first engaging element 140 is connected to the first hole 130 of the top element 120 (see...). Figure 3 The second engaging element 142 engages with the second hole 132 of the top element 120 (see...). Figure 2 The first engaging element 140 and the second engaging element 142 are joined to secure the top element 120 to the bottom element 122. The shapes and dimensions of the first engaging element 140 and the second engaging element 142 correspond to the shapes and dimensions of the first hole 130 and the second hole 132, respectively. In the illustrated embodiment, the first engaging element 140 and the second engaging element 142 are circular. Alternatively, the first engaging element 140 and the second engaging element 142 may have square, rectangular, elliptical, or other shapes.

[0041] Furthermore, the first engaging element 140 and the second engaging element 142 herein include mechanical fasteners. Mechanical fasteners may be embodied as bolts, screws, pins, rivets, etc. In alternative embodiments, the first engaging element 140 and the second engaging element 142 may include lugs extending from the left arm 136 and the right arm 138, respectively. It should be noted that this disclosure does not limit the shape or design of the first engaging element 140 and the second engaging element 142, and the first engaging element 140 and the second engaging element 142 may include various other shapes and designs. Furthermore, in some instances, a bayonet structure may be used to removably connect the top element 120 to the bottom element 122. Although the bottom element 122 herein includes two engaging elements 140 and 142, the total number of engaging elements 140 and 142 may vary based on the total number of holes 130 and 132 in the top element 120.

[0042] refer to Figure 4 and Figure 5 The handle 116 also includes a second portion 144 that defines a base element 124. Furthermore, the base element 124 of the second portion 144 at least partially covers the top element 120 of the first portion 118, or the top element 120 of the first portion 118 at least partially covers the base element 124 of the second portion 144. More specifically, in one embodiment, the base element 124 is designed to partially or completely cover the top element 120 such that there is no gap between the base element 124 and the top element 120. This disclosure shows the base element 124 partially covering the side 134 of the top element 120 (e.g., Figure 1 (Best shown in the diagram). This will prevent any foreign particles from moving between the base element 124 and the top element 120. In another example, the top element 120 is designed to partially or completely cover the base element 124, such that there is no gap between the base element 124 and the top element 120. This arrangement of the top element 120 and the base element 124 limits any gap between the top element 120 and the base element 124 to prevent any foreign particles from passing through. It should be noted that the bottom element 122 of the first portion 118 is disposed between the top element 120 and the base element 124.

[0043] The first portion 118 is movable relative to the second portion 144. Furthermore, the movement of the first portion 118 relative to the second portion 144 allows for actuation of the mechanism 110 based on user actions on the top element 120 of the first portion 118. In some instances, when the movable basket 112 is in the second position "P2", the base element 124 of the second portion 144 can at least partially receive the first portion 118. In one embodiment, the second portion 144 can be fixed to the pump housing 102.

[0044] Furthermore, the first portion 118 is connected to the second portion 144, allowing the top element 120 of the first portion 118 to be removed from the first portion. For example... Figure 5 and Figure 6 As shown, when the top element 120 is removed, a gap 146 exists between the bottom element 122 and the second portion 144. Furthermore, when the top element 120 is attached to the bottom element 122, a pair of sides 134 can cover the gap 146. Removal of the top element 120 of the first portion 118 allows access to the base element 124 of the second portion 144. Additionally, in some embodiments, the first portion 118 and the second portion 144 can be removably connected by one or more of screws, snap-fit ​​mechanisms, and pins. In the illustrated embodiment, the first portion 118 and the second portion 144 are removably connected by a snap-fit ​​mechanism. Alternatively, the first portion 118 and the second portion 144 can be removably connected by any other means commonly used or known in the art.

[0045] This disclosure provides an improvement to the handle 116 for a pump 100 (preferably a submersible pump 100). A first portion 118 and a second portion 144 are designed to allow a user to easily grip the handle 116 for moving, cleaning, or other maintenance purposes of the pump 100. The portions of the handle 116 described herein are designed to be ergonomic, allowing the user to comfortably actuate the top element 120 of the first portion 118 to switch the position of the movable basket 112 between a first position “P1” and a second position “P2”. Furthermore, this disclosure can be readily applied to any other portion of the pump 100, or even to parts other than the handle 116. The techniques of this disclosure can be readily applied to different movable portions of the mechanism 110, particularly those susceptible to foreign particle intrusion.

[0046] Furthermore, the handle 116 includes a top element 120 that is removably coupled to the bottom element 122. The top element 120 has a simple design and is a cost-effective component. Additionally, the top element 120 restricts the passage and settling of foreign particles in the base element 124. Removing the top element 120 makes the base element 124 easily accessible for cleaning. Furthermore, the removable coupling of the top element 120 to the bottom element 122 is configured to allow for quick and easy attachment / disengagement of the top element 120 and the bottom element 122.

[0047] Preferred embodiments and examples of this disclosure have been disclosed in the accompanying drawings and description. Although specific terms have been used, they are used in a general descriptive sense only and are not intended to limit the scope of this disclosure as set forth in the appended claims.
