Description

Pump and handle associated with pump

Technical Field

The present disclosure relates to a pump. More particularly, the present disclosure relates to a submersible pump and a handle associated with the pump.

Background

A pump, such as a submersible pump (or auxiliary pump or electric submersible pump), is a device that can be immersed in a fluid medium to be pumped. Generally, submersible pumps are used for different applications, such as clean water operations, sewage operations, etc. These applications may require adjusting the height of the pump, transporting the pump from one location to another, etc.

Some pumps may include a height adjustment mechanism that allows the height of the pump to be adjusted. However, the height adjustment mechanism is complex in design and includes multiple parts that move relative to one another. The height adjustment mechanism also includes a plurality of contact surfaces associated with the movable portion. Furthermore, dirt particles present in the fluid being pumped may become trapped between the movable parts. In some cases, dirt particles may clog one or more portions of the height adjustment mechanism, which may in turn affect operation of the submersible pump.

In addition, conventional submersible pumps include handles that allow the pump to be transported from one location to another. The handle acts as a "trigger" to allow the position of the pump to be changed. The current design of handles associated with pumps may expose portions of the handle, allowing foreign particles to enter. In addition, such handles can present difficulties in cleaning and other maintenance operations of the handles. Accordingly, there is a need for an improved handle design for a submersible pump that is user friendly and ergonomic. Furthermore, it is desirable that the handle allows easy cleaning and maintenance of the handle.

CN patent application 21,0961,650 (hereinafter' 650 reference) describes a low noise food processor. The low noise food processor comprises a handle, a handle overturning cover and a limiting groove. The handle flip cover and the side wall of the machine housing may be directly detachably connected such that a user may detach the handle flip cover. In addition, the handle flip cover is hingedly connected to the side wall by a hinge axis about the bottom of the handle flip cover. However, the handle described in the' 650 reference is associated with a food processor. Furthermore, such an arrangement of the handle flip cover and the handle is complicated, and may cause the handle to be susceptible to intrusion of foreign particles.

CN patent application 204,226,273 (hereinafter referred to as' 273 reference) discloses a telescopic handle structure for a small submersible pump. The telescopic handle structure comprises a pump body and a handle. The connecting portion perpendicular to the spatial horizontal base surface is provided on the outer surface of the pump body. Furthermore, the handle is connected to the connecting portion in a telescopic manner. The connecting portions are symmetrically distributed on both sides of the outer surface of the pump body on the guide flange portions. Further, a stopper groove is provided on each of the left and right sides of each guide flange portion. The telescoping handle structure of the' 273 reference appears to include a two-part handle structure that appears to be cumbersome, inconvenient, and space-constrained, which may limit access between the handle and the guide flange portion, as well as other implementation drawbacks.

Disclosure of Invention

In view of the above, it is an object of the present disclosure to solve or at least reduce the above drawbacks. This object is at least partly achieved by a new design of 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 member and a bottom member. The handle also includes a second portion defining a base member. The base element of the second part at least partially covers the top element of the first part, or the top element of the first part at least partially covers the base element of the second part. Further, the first portion and the second portion may be movable relative to each other. The pump is characterized in that the first portion is coupled with the second portion such that a top element of the first portion is removable from the second portion.

The handle of the present disclosure has a user-friendly and ergonomic design that makes the handle of the pump easy to clean and maintain. The handles described herein also reduce any gap between the movable portions (i.e., the first portion or the second portion) of the handles from being exposed to fluid. This feature in turn may reduce any risk of clogging of the movable part due to foreign particles. Furthermore, the top element may be easily attached/detached to allow easy access for cleaning of the handle portion, here the bottom element and the second portion.

According to an embodiment of the present disclosure, removal of the top element of the first portion allows access to the base element of the second portion.

This feature provides easy access to the handle portion (i.e. the base element of the second portion) for cleaning in order to remove any obstructions or foreign matter from the movable portion of the handle.

According to embodiments of the present disclosure, the first portion and the second portion are removably coupled by one or more of screws, snap-fits, and pins. This coupling technique allows for quick attachment and detachment of the first and second portions.

According to an embodiment of the present disclosure, the handle defines a left arm and a right arm. The top element of the first portion is removably coupled to one or more of the left and right arms. This feature allows easy and quick removal of the top element to access the base element without the need for additional tools.

According to embodiments of the present disclosure, the left and right arms of the handle are at least partially engaged with the mechanism of the pump. This provides a robust arrangement for the handle and mechanism of the pump and also helps to simplify the technique of the moveable basket of the trigger mechanism.

According to an embodiment of the present disclosure, the pump further comprises a moveable basket that moves between a first position and a second position. Actuation of the first portion of the handle biases the movable basket into one of the first position and the second position. This feature allows for a simple and user friendly operation for switching the movable basket between the first and second positions. Furthermore, this feature may allow the pump to be used in different modes, such as a clean water mode and a sewage mode.

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

According to an embodiment of the present disclosure, the pump is a submersible pump. The submersible pump is used in clear water mode and dirty water mode, however the pump may be any pump used or known in the art.

Other features and aspects of the present disclosure will become apparent from the following description and the accompanying drawings.

Detailed Description

The present disclosure will be described more fully hereinafter with reference to the accompanying drawings, in which example embodiments of the disclosure incorporating one or more aspects of the disclosure are shown. This disclosure may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough 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 with other embodiments and may even be used with other types of structures and/or methods. In the drawings, like numbering represents like elements.

Certain terminology is used herein for convenience only and is not to be taken as a limitation on the present disclosure. For example, "upper," "lower," "front," "rear," "side," "longitudinal," "lateral," "transverse," "upward," "downward," "forward," "rearward," "sideways," "left," "right," "horizontal," "vertical," "above," "inner," "outer," "inward," "outward," "top," "bottom," "upper," "lower," "center," "middle," "intermediate," "between," "end," "adjacent," "near," "distal," "remote," "radial," "circumferential," etc. describe only the configuration shown in the figures. In fact, the components may be oriented in any direction and the terminology, therefore, should be understood as encompassing such variations unless specified otherwise.

Fig. 1 shows a perspective view of a pump 100. The present disclosure relates to a pump 100. The pump 100 is a submersible pump 100. However, the present disclosure may be readily implemented with any pump used or known in the art. The pump 100 may be used in a variety of fluid treatment operations to pump fluids. The fluid may comprise water or any other fluid having a different viscosity. In one example, pump 100 may comprise a multistage centrifugal pump that operates in a vertical position.

Pump 100 includes a pump housing 102. The pump housing 102 is generally hollow and retains the various components of the pump 100 therein. Pump 100 includes a prime mover (not shown) disposed in a pump housing 102. The prime mover generates operating power and may include a tightly sealed motor (not shown). The pump housing 102 has an inlet 104 and an outlet 106 for fluid. Fluid is pumped in from the inlet 104 and pumped out from the outlet 106. The outlet 106 is connected with a hose connector 108 which may allow connection of a hose (not shown) for pumping fluid. Pump 100 may also include other components (not shown), such as impellers, shafts, bearings, and the like.

As shown in fig. 2, pump 100 includes a mechanism 110. In addition, the mechanism 110 includes a movable basket 112. The movable basket 112 is adapted to move between a first position "P1" (not shown) and a second position "P2", as shown in the figures. The mechanism 110 allows the movable basket 112 to switch between a first position "P1" and a second position "P2". The first position "P1" is an extended position of the movable basket 112. Further, the second position "P2" is the retracted position of the movable basket 112. The first position "P1" and the second position "P2" of the movable basket 112 provide the necessary change in the inlet area of the inlet 104. Furthermore, the first position "P1" and the second position "P2" adjust the inlet 104 of the pump 100 to operate the pump 100 in the dirty water mode and the clean water mode. More specifically, the first position "P1" and the second position "P2" of the movable basket 112 correspond to the dirty water mode and the clean water mode, respectively. Since the dirty water mode requires a larger inlet area than the clean water mode to ensure efficient operation of the pump 100, the movable basket 112 is moved to the first position "P1" for operating the pump 100 in the dirty water mode.

Operation of the pump 100 in the first position "P1" allows for treatment of dirty water, wherein dirt particles of different sizes may enter without any obstruction. To switch to the first position "P1", the movable basket 112 is moved within the pump housing 102 relative to the pump housing. The movement of the movable basket 112 to the first position "P1" increases the overall height of the pump 100.

The first position "P1" of the movable basket 112 allows one or more inlet openings (not shown) provided on the movable basket 112 to be exposed. The inlet opening is disposed adjacent to the inlet 104. In one example, the 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 the pump 100 to be set for different applications depending on the desired size of the inlet opening based on the switching of the movable basket 112 between the first position "P1" and the second position "P2".

Furthermore, operation of pump 100 in the second position "P2" allows fresh water to be treated. In the second position "P2", fresh water may enter the pump 100 from the inlet 104. The second position "P2" of the movable basket 112 restricts the flow of any large sized particles. To switch to the second position "P2", the movable basket 112 is moved within the pump housing 102 relative to the pump housing. The movement of the movable basket 112 to the second position "P2" reduces the overall height of the pump 100. Furthermore, in the second position "P2" of the movable basket 112, the inlet opening is partially covered or completely covered by the pump housing 102, depending on the application requirements.

Although the present disclosure discloses two positions, namely, a first position "P1" and a second position "P2", practical implementations of the present 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". Further, the multiple positions may then allow for multiple modes of operation of the pump 100.

Further, the pump 100 includes a pump body 114. The pump body 114 or mechanism 110 may include any technology, device, component that allows the movable basket 112 to move and actuate between the first position "P1" and the second position "P2". Pump 100 also includes a handle 116 adapted to couple with pump body 114. In some embodiments, the handle 116 may be adapted to couple with the housing 114 or any other portion of the pump 100 without limiting the present disclosure. The handle 116 allows a user to carry the pump 100. In addition, the handle 116 serves as a "trigger" for switching the movable basket 112 between the first position "P1" and the second position "P2". The handle 116 includes a first portion 118 defining a top member 120 and a bottom member 122 (best shown in fig. 5). Further, actuation of the first portion 118 of the handle 116 is adapted to bias the movable basket 112 into one of the first position "P1" and the second position "P2". The first portion 118 acts as an actuator to change the position of the movable basket 112. Further, the first portion 118 of the handle 116 may be actuated based on touching, pressing and holding, etc. In some embodiments, the handle 116 may include additional components or combinations of components to achieve the desired function of actuating or triggering movement of the movable basket 112.

The present disclosure relates to a top element 120. The top member 120 will now be explained in detail. Fig. 3 shows a perspective view of the top element 120 of the first portion 118. It should be noted that the shape of the top element 120 generally corresponds to the shape of the upper portion 123 (see fig. 2) adjacent to the bottom element 122 (see fig. 2). The top member 120 includes a "C" shaped design. However, depending on the design of the handle 116, the top member 120 of the first portion 118 may have any shape and size that allows the top member 120 to cover the base member 124 (see fig. 4, 5, and 6) depending on the design of the handle 116.

The material of the top member 120 may comprise plastic, metal, wood, and the like. The top member 120 defines a first end 126 and a second end 128. Top member 120 defines an inner surface 129 and an outer surface 131 opposite inner surface 129. Further, the top member 120 includes a first aperture 130 defined at the first end 126 and a second aperture 132 defined at the second end 128. The first aperture 130 is aligned with the second aperture 132. In the illustrated embodiment, the first aperture 130 and the second aperture 132 are circular in shape. Alternatively, the first and second holes 130 and 132 may have a square shape, a rectangular shape, an oval shape, or the like. It should be noted that the top member 120 may include any number of apertures having various shapes and sizes, without limiting the scope of the present disclosure. In the example shown, the first and second holes 130, 132 are implemented as through holes. In some embodiments, top member 120 may include a pair of protrusions, grooves, or any other connecting element protruding from outer surface 131 or inner surface 129 of top member 120 to engage with a corresponding mating element on bottom member 122.

Further, the top member 120 includes a pair of sides 134, only one of which is shown herein. In some examples, the pair of sides 134 may be parallel to each other. In other examples, each side 134 may be disposed at an angle such that the pair of sides 134 are not parallel to each other. Further, the top member 120 defines an opening 135 to receive the bottom member 122 when the top member 120 is coupled to the bottom member 122 and the base member 124. Further, 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.

As shown in fig. 2, the handle 116 defines a left arm 136 and a right arm 138, wherein the top element 120 of the first portion 118 is removably coupled (or click-coupled) to one or more of the left arm 136 and the right arm 138. Left arm 136 and right arm 138 form a portion of bottom member 122. The bottom member 122 comprises 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 with the top element 120. The material of the bottom member 122 may comprise plastic, metal, wood, or the like. In some embodiments, removing the top element 120 may allow for assembly or disassembly of different portions or components of the mechanism 110 or pump 100. More specifically, removing the top member 120 may allow for assembling or disassembling the left and right arms 136, 138 or any other portion of the handle 116. Thus, this simple and easy to remove arrangement of the top element 120 may allow for efficient and user-friendly field cleaning, or even cleaning after removal of a portion or component from the handle 116.

The left and right arms 136, 138 of the bottom member 122 extend downwardly toward the inlet 104 of the pump 100. Left arm 136 and right arm 138 of handle 116 are adapted to at least partially engage mechanism 110 of pump 100. Engagement of the left and right arms 136, 138 with the mechanism 110 may allow the movable basket 112 to switch between the first and second positions "P1", P2 "based on actuation of the first portion 118 of the handle 116.

The bottom member 122 of the first portion 118 includes a first engagement member 140 (shown in fig. 5) and a second engagement member 142 (shown in fig. 2). The first engagement member 140 is disposed on the left arm 136 and the second engagement member 142 is disposed on the right arm 138. Further, the first engagement member 140 engages the first aperture 130 (see fig. 3) of the top member 120 and the second engagement member 142 engages the second aperture 132 (see fig. 2) of the top member 120 to secure the top member 120 to the bottom member 122. The shape and size of the first and second engagement elements 140 and 142 correspond to the shape and size of the first and second apertures 130 and 132, respectively. In the illustrated embodiment, the first and second engagement elements 140, 142 are circular in shape. Alternatively, the first and second engagement elements 140 and 142 may have a square shape, a rectangular shape, an oval shape, or the like.

Further, the first and second engagement elements 140, 142 herein comprise mechanical fasteners. The mechanical fasteners may be embodied as bolts, screws, pins, rivets, etc. In alternative embodiments, the first and second engagement elements 140, 142 may include lugs extending from the left and right arms 136, 138, respectively. It should be noted that the present disclosure is not limited to the shape or design of the first and second engagement elements 140, 142, and that the first and second engagement elements 140, 142 may include a variety of other shapes and designs. Further, in some examples, the top element 120 and the bottom element 122 may be removably coupled using a bayonet structure. Although the bottom member 122 includes two engagement members 140 and 142 herein, the total number of engagement members 140 and 142 may vary based on the total number of apertures 130 and 132 in the top member 120.

Referring to fig. 4 and 5, the handle 116 further includes a second portion 144 that defines the base member 124. Further, 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 example, the base member 124 is designed to partially or completely cover the top member 120 such that there is no gap between the base member 124 and the top member 120. The present disclosure shows the base member 124 partially covering the side 134 of the top member 120 (as best shown in fig. 1). This will cause the base member 124 to not allow any foreign particles to move between the base member 124 and the top member 120. In another example, the top member 120 is designed to partially or completely cover the base member 124 such that there is no gap between the base member 124 and the top member 120. This arrangement of top member 120 and base member 124 limits any gap between top member 120 and base member 124 to avoid 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.

The first portion 118 is movable relative to the second portion 144. Further, movement of the first portion 118 relative to the second portion 144 allows for actuation of the mechanism 110 based on a user action on the top element 120 of the first portion 118. In some examples, the base element 124 of the second portion 144 may at least partially receive the first portion 118 when the movable basket 112 is in the second position "P2". In one embodiment, the second portion 144 may be secured to the pump housing 102.

Further, the first portion 118 is coupled with the second portion 144 such that the top element 120 of the first portion 118 may be removed from the second portion. As shown in fig. 5 and 6, when the top element 120 is removed, a gap 146 exists between the bottom element 122 and the second portion 144. Further, when top element 120 is coupled to bottom element 122, a pair of sides 134 may cover gap 146. Removal of the top member 120 of the first portion 118 allows access to the base member 124 of the second portion 144. Further, in some embodiments, the first portion 118 and the second portion 144 may be removably coupled by one or more of screws, snap-fits, and pins. In the illustrated embodiment, the first portion 118 and the second portion 144 are removably coupled by a snap-fit arrangement. Alternatively, first portion 118 and second portion 144 may be removably coupled by any other means commonly used or known in the art.

The present disclosure provides improvements to the handle 116 for the pump 100, preferably the submersible pump 100. The first portion 118 and the second portion 144 are designed so that a user can easily grasp the handle 116 for movement or cleaning and other maintenance purposes of the pump 100. Portions of the handle 116 described herein are designed to be ergonomic so that a user can comfortably actuate the top element 120 of the first portion 118 to switch the position of the movable basket 112 between the first position "P1" and the second position "P2". Furthermore, the present disclosure may be readily adapted to any other multiple portion arrangement of pump 100, even not handle 116. The techniques of the present disclosure may be readily applied to different movable portions of mechanism 110, particularly portions that are susceptible to intrusion by foreign particles.

Further, the handle 116 includes a top member 120 that is removably coupled to a bottom member 122. The top element 120 is of simple design and is a cost-effective component. In addition, the top member 120 limits the passage and settling of foreign particles in the base member 124. The top member 120 is removed so that the base member 124 is readily accessible for cleaning thereof. Furthermore, the removable coupling of the top element 120 with the bottom element 122 is arranged to allow for a quick and easy attachment/detachment of the top element 120 and the bottom element 122.

In the drawings and specification, there have been disclosed preferred embodiments and examples of the disclosure and, although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the disclosure being set forth in the following claims.
