Description

Technical Field

[0001] The present disclosure relates to the field of water pumps, and particularly to an air-blocking prevention water pump. Background Art

[0002] As a key device for liquid transmission, the design and cleaning method of the exhaust hole of a water pump are directly related to the operation efficiency and service life of the water pump. The exhaust hole is used to discharge the air in the pump body to ensure the normal operation of the water pump. When the exhaust hole is directly opened on the volute of the water pump, since the liquid may directly spray out from the exhaust hole during the operation of the water pump, it will not only cause waste of water resources, but also pose a safety hazard to the surrounding environment and operators. Therefore, to avoid such problems, the exhaust hole is usually placed in a concealed position of the water pump. However, when the water pump transports sewage containing impurities, these impurities are easily accumulated at the exhaust hole and cause blockage. Moreover, since the exhaust hole is located in a concealed position of the water pump, it is very difficult for users to directly observe and clean these blockages, making daily maintenance and cleaning extremely difficult, increasing the operation cost and risk of users. Traditional solutions often require the disassembly of the entire water pump, which is not only complex and time-consuming, but also may cause the sealing performance of the water pump to decline due to frequent disassembly, thereby affecting the service life and operation efficiency of the water pump. Utility Model Content

[0003] To solve at least a part of the above problems, the present disclosure provides a novel air-blocking prevention water pump, which effectively solves the problem that the exhaust hole is difficult to clean in the prior art by setting a unique exhaust hole cleaning structure. The present disclosure has the advantages of simple structure, convenient operation, time-saving and labor-saving, significantly improves the maintenance efficiency and operation stability of the water pump, and improves the user experience.

[0004] According to an embodiment of the present disclosure, there is provided an air-blocking prevention water pump, including: a pump body, on which an exhaust hole is opened; a mounting shell, mounted on the outer wall of the pump body corresponding to the exhaust hole; and a cleaning needle, disposed in the mounting shell and facing the exhaust hole, for inserting and cleaning the exhaust hole.

[0008] In one implementation of this embodiment, the top of the mounting shell extends downward to form the water blocking portion.

[0009] In one implementation of this embodiment, the cleaning needle includes a limiting portion, which is limit-connected to the elastic reset member and is used to limit the moving path of the cleaning needle.

[0010] In one implementation of this embodiment, the elastic reset member includes a W-shaped reset member.

[0011] In one implementation of this embodiment, the elastic reset member includes a spring reset member or a rubber reset member.

[0012] In one implementation of this embodiment, the exhaust hole is in a normally open state.

[0013] In one implementation of this embodiment, the connection manner between the mounting shell and the pump body includes screw connection, welding or adhesive connection.

[0014] For the anti-air-lock water pump proposed by the present disclosure, by arranging a cleaning structure on the outer wall of the pump body facing the exhaust hole, the user can directly operate the cleaning needle to clean the exhaust hole, improving the convenience of cleaning the exhaust hole of the water pump; further, the cleaning needle and the elastic reset member are combined to form a self-resetting structure, and the cleaning needle can self-reset under the action of the elastic reset member after the user presses to complete the cleaning, with a simple structure and convenient operation, providing a good user experience for the user; in addition, by arranging a water blocking portion at the exhaust hole to block possible liquid splashing at the exhaust hole, the position design of the exhaust hole is more free and does not need to be located in a hidden place.

[0019] In the following detailed description of the preferred embodiments, reference will be made to the accompanying drawings that form a part of the present disclosure. The accompanying drawings illustrate, by way of example, specific embodiments that can implement the present disclosure. The example embodiments are not intended to exhaust all embodiments according to the present disclosure. It can be understood that other embodiments can be utilized and structural or logical modifications can be made without departing from the scope of the present disclosure. Therefore, the following detailed description is not restrictive, and the scope of the present disclosure is defined by the appended claims.

[0020] Before introducing the embodiments of the present disclosure, some terms involved in the present disclosure are first explained to better understand the present disclosure.

[0021] The terms "a", "a set of", or "one" and the like used in the present disclosure do not indicate a limitation in quantity, but rather indicate the existence of at least one. The terms "comprising", "including" and the like used in the present disclosure should be understood as open-ended terms, that is, "including / including but not limited to", indicating that other content can also be included. The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment" and so on. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0022] As described above, in view of the technical problem that the exhaust hole position of the water pump in the prior art is concealed and it is difficult to perform daily maintenance and cleaning, the present disclosure proposes a new type of air-blocking prevention water pump, which can be a self-priming pump, a centrifugal pump, a mixed-flow pump, etc., and the present disclosure does not limit its type.

[0023] As Figures 1-3 shown, an exemplary air-blocking prevention water pump 100 is proposed in an embodiment of the present disclosure. The air-blocking prevention water pump 100 includes a pump body 110, a mounting shell 120 and a cleaning needle 130. Among them, an exhaust hole 112 is opened on the pump body 110, and the exhaust hole 112 is used to quickly discharge the air in the water pump and the pipeline to ensure the normal operation of the water pump and prevent performance degradation or failure caused by air blockage.

[0024] In some examples, the exhaust hole 112 is directly opened on the volute of the water pump. Since air usually floats and accumulates at higher positions in the pipeline, in order to effectively exhaust air, the exhaust hole 112 should generally be set at a higher position (such as the middle, top, etc. of the pump body), and it should be avoided to be set in dead corners or low-lying areas to prevent air accumulation. In some examples, the exhaust hole 112 is in an always-open state, which facilitates equipment exhaust and reduces the operation steps of users.

[0025] The mounting shell 120 is mounted on the outer wall of the pump body 110 corresponding to the exhaust hole 112. The mounting shell 120 is close to the opening position of the exhaust hole and is used to accommodate or support the cleaning needle 130, providing a deployment position for the cleaning needle and facilitating the user to operate the cleaning needle nearby. In some examples, the connection method between the mounting shell 120 and the pump body 110 can be screw connection, welding or adhesive connection. Among them, a detachable connection method such as screw connection is preferably used between the mounting shell 120 and the pump body 110, which is convenient for fault repair and part replacement. In some examples, as Figure 3 shown, the mounting shell 120 extends outward with a mounting portion, and a mounting hole is opened on this mounting portion for mounting the mounting shell to the pump body. The mounting portion in the figure extends from the bottom to the left and right sides. In other examples, the mounting portion can also be located at the top or middle, and can also extend upward or downward.

[0026] The cleaning needle 130 is arranged in the mounting shell 120 facing the exhaust hole 112 (for example, in the direction shown by the axis A1A2) and is used to insert into the exhaust hole 112 for cleaning. The cleaning needle 130 is directly opposite the exhaust hole 112. When the user operates the cleaning needle from one end, the other end of it can be inserted into the exhaust hole to clean the impurities in the exhaust hole. In some examples, the cleaning needle is a pressing operation structure, that is, the user inserts the cleaning needle into the exhaust hole by pressing. In other examples, the cleaning needle is a rotary operation structure, that is, the user rotates the cleaning needle to gradually insert it into the exhaust hole.

[0027] In some examples, the water pump 100 further includes an elastic resetting member 140. The elastic resetting member 140 is arranged in the mounting shell 120 and connected to the cleaning needle 130 to form a self-resetting structure. Specifically, when the user presses and operates to insert the cleaning needle into the exhaust hole, the elastic resetting member 140 undergoes elastic deformation. When the user stops pressing the operation, the cleaning needle resets under the action of the elastic force of the elastic resetting member.

[0028] Optionally, the material of the elastic resetting member can be comprehensively determined according to factors such as the specific application occasion, performance requirements, and cost consideration of the water pump, including spring steel, rubber, plastic, stainless steel, high-speed steel, deformation alloy, bronze, shape memory alloy, etc.

[0029] In some examples, the elastic reset member can be selected as a spring reset member. The inner wall of the installation shell fixes and limits the spring reset member, and the cleaning needle 130 is inserted into and connected with the spring reset member. When the user presses the cleaning needle to insert it into the exhaust hole, the spring reset member is compressed and elastically deformed. When the user stops pressing, the spring reset member drives the cleaning needle to reset.

[0030] In some examples, the elastic reset member is a rubber reset member. The shape design of the rubber reset member is more flexible than that of the spring. Figures 1-3 Taking the W-shaped elastic reset member as an example, the middle part of the W-shaped elastic reset member cooperates with the cleaning needle. When the cleaning needle is pressed, the middle part elastically deforms to provide a reset force for the cleaning needle; the peripheral side walls ( Figure 1 and Figure 2 showing the upper and lower side walls) of the W-shaped elastic reset member are connected to the inner wall of the installation shell. When the cleaning needle is pressed, the peripheral side walls basically do not deform, which is used to improve the overall stability of the cleaning structure and reduce the frictional resistance when the middle part elastically deforms. In some other examples, the elastic reset member is an n-shaped elastic reset member, that is, compared with the W-shaped elastic reset member, the peripheral side walls are reduced, and the structure is simpler.

[0031] In some examples, the cleaning needle 130 sequentially includes a pressing part 132, a limiting part 134, and a cleaning part 136 along the direction towards the exhaust hole. Among them, the pressing part 132 is a planar structure for the user to press and operate. The limiting part 134 is limit-connected with the elastic reset member 140 and is used to limit the movement path of the cleaning needle, which can both limit the part of the cleaning needle entering the exhaust hole and prevent the cleaning needle from falling off. The cleaning part 136 enters the exhaust hole 112 after the pressing operation. In some examples, the maximum outer diameter of the cleaning part 136 is smaller than the aperture of the exhaust hole. In some examples, the length of the cleaning part 130 is greater than the thickness of the outer wall of the pump body.

[0032] In some examples, the water pump 100 further includes a water blocking part 150. The water blocking part 150 is arranged between the exhaust hole 112 and the cleaning needle 130 and is used to block the liquid splashing at the exhaust hole 112. A cleaning needle through hole 152 is opened on the water blocking part 150 for the cleaning needle 130 to pass through to clean the exhaust hole 112.

[0033] The cleaning needle 130 includes a cleaning state (that is, the state when it is operated to clean the exhaust hole and the elastic reset member elastically deforms) and a non-cleaning state (that is, the state when it is not operated and the elastic reset member does not elastically deform). In some examples, when the cleaning needle 130 is in the non-cleaning state, the cleaning needle 130 is inserted into the cleaning needle through hole 152. The cleaning needle through hole 152 can be used to limit the movement path of the cleaning needle and form a closed structure to prevent liquid or other impurities from entering the interior of the installation shell through the cleaning needle through hole 152 and affecting the service life of the spring reset member.

[0034] In some examples, the top of the mounting shell 120 extends downward to form the water blocking portion 150. The water blocking portion is part of the mounting shell and is integrally formed from the same material. In other examples, the mounting shell 120 and the water blocking portion 150 are separate parts and can be fixedly connected by means such as welding, snap connection, and bonding. The water blocking portion 150 can be a flat plate structure or other shaped structures that can achieve the water blocking function. A certain gap is reserved between the water blocking portion 150 and the exhaust hole 112 for gas discharge.
