Description

Technical Field

[0001] This application relates to the field of water purification equipment technology, specifically to a portable water purifier. Background Technology

[0002] Portable water purifiers are a common type of water purification equipment, typically used in field or outdoor operations. Existing portable water purifiers usually consist of a main body and a hand-operated assembly. The main body contains a filter cartridge, while the hand-operated assembly includes a handle and a piston structure. Users hold the handle and move the piston back and forth to force the water to be purified into the filter cartridge.

[0003] The handle is usually an integrated structure. One end of the handle is fixedly connected to the piston structure or is integrated with it, while the other end extends away from the body, so that the handle and the body are combined to form a figure-7 structure. This type of structure not only makes it easier for users to hold the handle, but also extends the lever arm when pressing up and down while holding the handle, thus making it easier for users to press up and down. However, the drawback of the figure-7 structure is that it makes the water purifier larger in size, which is inconvenient to store, and the handle is easily damaged by accident. Utility Model Content

[0004] This application provides a portable water purifier to improve or solve, to some extent, the technical problem that existing portable water purifiers are too large and inconvenient to store.

[0005] The technical solution adopted in this application is as follows:

[0006] A portable water purifier includes a body and a hand-operated assembly. The body contains a filter cartridge. The hand-operated assembly includes a handle and a piston structure. The handle drives the piston structure to reciprocate, forcing water to be purified into the filter cartridge. The piston structure has a transmission component for transmitting pressure from the handle. The handle has a pivot shaft pivotally connected to the transmission component. A locking structure is provided between the handle and the transmission component. The handle has a locking stroke, an unlocking stroke, and a retracting stroke relative to the transmission component. When the handle performs the locking stroke, the locking structure is locked, thereby confining the handle and the transmission component to a relatively fixed state. When the handle performs the unlocking stroke, the locking structure is unlocked, allowing the handle to rotate relative to the transmission component via the pivot shaft to perform the retracting stroke.

[0007] In this technical solution, the transmission component and handle are pivotally connected via a pivot shaft, and a locking structure is introduced, along with three strokes for the handle: locking, unlocking, and retracting, enabling multi-state switching of the handle. In a preferred embodiment, the handle can form a "7" shape with the body when in the locking stroke, facilitating grip and effortless pressing. When in the retracting stroke, the handle can rotate towards the body, forming a nearly parallel position close to the body, thus significantly reducing its size. With the locking structure engaged, the handle and transmission component are fixed, ensuring stable force transmission during pressing. After unlocking, the handle can rotate around the pivot shaft to the retracted position, significantly reducing the overall size of the water purifier and solving the problem of inconvenient storage with the traditional "7" shape. Furthermore, segmented stroke control prevents accidental mechanical damage, balancing ease of operation and equipment durability.

[0008] The locking structure includes a protrusion on one of the handle and the transmission member and a recess on the other. The protrusion engages with the recess to lock the device, and the protrusion disengages from the recess to unlock the device.

[0009] In this technical solution, the locking structure uses the mechanical cooperation of the convex and concave parts to achieve locking. The structure is simple and reliable, and locking and unlocking can be completed without complex driving devices, reducing manufacturing costs. Moreover, the physical limit of the convex and concave cooperation can effectively resist the reverse force when pressing, avoid locking failure, and improve operational safety.

[0010] The transmission component is provided with a slide rail, and the pivot shaft passes through the slide rail. When the handle performs the locking stroke or the unlocking stroke, the pivot shaft slides along the slide rail; when the handle performs the retracting stroke, the pivot shaft rotates within the slide rail.

[0011] In this technical solution, the slide rail serves as both a guide rail for the pivot shaft to slide and a rotating hole structure for the pivot shaft to rotate, enabling a smooth transition of the handle in different strokes. When the handle performs the locking or unlocking stroke, the pivot shaft slides linearly along the slide rail to ensure precise alignment of the convex and concave structures. When stored, the pivot shaft rotates within the slide rail to avoid motion interference.

[0012] The protrusion is formed in the handle, the recess is formed in the slide rail, and when the locking structure is locked, the protrusion abuts against the inner wall of one end of the slide rail, and the pivot abuts against the inner wall of the other end of the slide rail.

[0013] In this technical solution, the protrusion is placed in the handle and the recess is integrated into the slide rail, which optimizes the spatial layout. The slide rail itself is used as a local carrier of the locking structure, which reduces the number of additional parts and simplifies the structure. Furthermore, the protrusion and the pivot shaft abut against the inner walls at both ends of the slide rail in both directions, forming a double force support when locking, which enhances the structural rigidity when pressed and reduces the risk of slide rail deformation.

[0014] The handle is provided with a locking slide, and the locking slide has an opening for the transmission member to slide into. When the transmission member slides into the locking slide, the handle performs the locking stroke. When the locking structure locks, it restricts the transmission member from sliding relative to the locking slide. When the transmission member slides out of the locking slide, the handle performs the unlocking stroke.

[0015] In this technical solution, by setting a locking slide in the handle, a guiding channel is provided for the cooperation between the handle and the transmission component, as well as for the handle to perform the locking and unlocking strokes. This allows the transmission component to slide into the locking slide along a preset path to lock with the handle, simplifying the user's operation steps (such as switching states by pushing or pulling in one direction). At the same time, the locking slide's wrapping effect on the transmission component disperses the local stress during locking, extending the life of the locking structure.

[0016] The locking slide is provided with a stop wall at the other end opposite to the opening. When the transmission member abuts against the stop wall, the locking structure completes the locking.

[0017] In this technical solution, the stop wall provides a clear end point for the sliding stroke of the transmission component. The physical block ensures that the locking structure is fully in place and limits the completion of the locking stroke, avoiding the problem of false locking caused by insufficient sliding. In addition, the stop wall can withstand the reverse impact force in the locked state, further improving the locking stability.

[0018] The locking slide is a straight structure, and the opening of the locking slide is located at one end of the handle.

[0019] In this technical solution, the linear locking slide and end opening design simplify the handle processing technology (such as one-time molding by stamping or injection molding), reduce production costs, and the linear movement of the handle and transmission components conforms to the user's intuitive operating habits, reducing the probability of misoperation. In addition, the end opening facilitates the transmission components to quickly align with the locking slide entrance.

[0020] The handle has a first connecting piece and a second connecting piece arranged opposite to each other, and the pivot shaft passes through and connects the first connecting piece and the second connecting piece, forming the opening between the first connecting piece and the second connecting piece.

[0021] In this technical solution, the symmetrical arrangement of the first connecting piece and the second connecting piece provides double-sided support for the pivot shaft, improving the structural stability of the pivot shaft and preventing shaft deflection caused by unilateral force. At the same time, the opening between the first connecting piece and the second connecting piece forms a clearance space, ensuring that the transmission component is not obstructed when sliding into the locking slide, thus improving the assembly fault tolerance rate.

[0022] The pivot shaft is located at the first end of the handle, the second end of the handle is provided with a first locking part, and the base of the body is provided with a second locking part. When the handle rotates in the first direction to perform the storage stroke, the first locking part and the second locking part are locked, thereby restricting the handle from rotating in the second direction opposite to the first direction.

[0023] In this technical solution, the cooperation between the first locking part and the second locking part realizes the self-locking function of the handle in the storage state. When the handle is rotated to the storage position in the first direction, the first locking part and the second locking part automatically lock to prevent the handle from being accidentally opened due to vibration or collision. At the same time, it limits the degree of freedom of reverse rotation to ensure that the storage state is firm and reliable, and the fixing can be completed without additional operation.

[0024] The second locking part is provided with a locking cavity and a buckle located in the locking cavity. The first locking part is provided with a slot adapted to the buckle. The second end of the handle enters the locking cavity so that the buckle engages with the slot, thereby confining the second end within the locking cavity.

[0025] In this technical solution, the nested engagement of the locking cavity and the locking groove achieves multiple locking mechanisms, including cavity enclosure and buckle embedding, which significantly improves the anti-disengagement capability in the stored state. Furthermore, the fit between the buckle and the locking groove allows for a certain amount of deformation, reducing wear during repeated opening and closing, and balancing locking strength and service life.

[0043] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0044] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0046] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0047] In this application, unless otherwise expressly specified and limited, the "above" or "below" of the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. In the description of this specification, references to terms such as "an embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0048] In the embodiments of this application, a portable water purifier is provided. For ease of explanation and understanding, the following descriptions are based on the illustrated product structure. Of course, those skilled in the art will understand that the above structure is merely a specific example and illustrative illustration, and does not constitute a specific limitation on the technical solution provided in this application.

[0049] Reference Figures 1 to 11As shown, the portable water purifier provided in this application includes a body 1 and a hand-operated assembly. The body 1 contains a filter element, and the hand-operated assembly includes a handle 2 and a piston structure. The handle 2 is used to drive the piston structure to reciprocate and force the water to be purified into the filter element. The piston structure is provided with a transmission component 3 for transmitting the pressure of the handle 2. The handle 2 is provided with a pivot shaft 4 pivotally connected to the transmission component 3. A locking structure is provided between the handle 2 and the transmission component 3. The handle 2 has a locking stroke, an unlocking stroke, and a retracting stroke relative to the transmission component 3. When the handle 2 performs the locking stroke, the locking structure is locked, thereby limiting the handle 2 and the transmission component 3 to a relatively fixed state. When the handle 2 performs the unlocking stroke, the locking structure is unlocked, thereby allowing the handle 2 to rotate relative to the transmission component 3 through the pivot shaft 4 to perform the retracting stroke. This application does not illustrate or limit the filter element and piston structure located within the body 1. They can refer to mature technologies in the prior art. For example, the filter element can be a reverse osmosis filter element, a carbon filter element, etc., and the piston structure can also include a piston cylinder, a piston disposed in the piston cylinder, and a piston rod connected to the piston. The transmission rod is connected to the piston rod.

[0050] In this technical solution, the transmission component 3 and the handle 2 are pivotally connected via a pivot shaft 4, and a locking structure and three strokes of the handle 2 (locking, unlocking, and retraction) are introduced, realizing multi-state switching of the handle 2. In a preferred embodiment, such as Figure 7 and Figure 8 The diagram shows that after the handle 2 completes its locking stroke, it is fixed to the transmission component 3. When the handle 2 completes its locking stroke, it combines with the body 1 to form a "7" shape, facilitating gripping and effortless pressing. In the locked state, the stability of the force arm transmission during pressing is ensured. Figure 9 and Figure 10 The image shows the state of handle 2 after it has completed the unlocking process. At this point, the folding process can begin. Figure 1 and Figure 2 The diagram shows the state of handle 2 after it has completed its retracted stroke. Handle 2 can rotate around pivot 4 to the retracted position, significantly reducing the overall size of the water purifier and solving the problem of inconvenient storage associated with the traditional L-shaped structure. Simultaneously, segmented stroke control prevents accidental mechanical damage, balancing ease of operation and equipment durability. When retracting, handle 2 can flip towards the body 1, forming a nearly parallel position with it near the body 1, further reducing its size.

[0051] Regarding the specific form of the locking structure, in the preferred embodiment, such as Figure 3 , Figure 4 and Figure 6As shown, the locking structure includes a protrusion 21 on the handle 2 and a recess 31 on the transmission member 3. Locking is achieved when the protrusion 21 and recess 31 engage, and unlocking is achieved when they disengage. The mechanical engagement of the protrusion 21 and recess 31 provides a simple and reliable locking structure, eliminating the need for complex drive devices, reducing manufacturing costs. Furthermore, the physical limiting effect of the protrusion-recessed engagement effectively resists the reverse force during pressing, preventing locking failure and improving operational safety. In other embodiments, a protrusion can be provided on the transmission member 3, and a recess on the handle 2, with the protrusion on the transmission member 3 and the recess on the handle 2 forming a lock. Additionally, as a preferred embodiment, a guide arc surface can be provided on at least one of the protrusion 21 and recess 31 to guide the engagement or disengagement of the protrusion 21 and recess 31. As another preferred embodiment, at least one of the protrusion 21 and recess 31 can be made of plastic or a metal part with a certain degree of plastic deformation capability, facilitating reliable engagement or disengagement through extrusion deformation.

[0052] Furthermore, such as Figures 2 to 4 As shown, the transmission component 3 is provided with a slide rail 32, and a pivot shaft 4 passes through the slide rail 32. When the handle 2 performs the locking or unlocking stroke, the pivot shaft 4 slides along the slide rail 32; when the handle 2 performs the retracting stroke, the pivot shaft 4 rotates within the slide rail 32. Figure 8 As shown, when handle 2 performs its locking stroke, pivot 4 slides to the right end of slide rail 32 (the end closest to body 1), as... Figure 10 As shown, when the handle 2 performs the unlocking stroke, the pivot shaft 4 slides to the left end of the slide rail 32 (the end away from the body 1). The slide rail 32 serves as both a guide rail for the sliding of the pivot shaft 4 and a rotating hole structure for the rotation of the pivot shaft 4, achieving a smooth transition of the handle 2 in different strokes. When the handle 2 performs the locking or unlocking stroke, the pivot shaft 4 slides linearly along the slide rail 32, ensuring precise alignment of the convex and concave structures. When stored, the pivot shaft 4 rotates within the slide rail 32 to avoid motion interference.

[0053] Furthermore, such as Figure 3 , Figure 4 , Figure 6 and Figure 8As shown, a protrusion 21 is formed in the handle 2, and a recess 31 is formed within the slide rail 32. When the locking structure is engaged, the protrusion 21 abuts against the inner wall of one end of the slide rail 32, and the pivot shaft 4 abuts against the inner wall of the other end of the slide rail 32. In this technical solution, the protrusion 21 is located in the handle 2, and the recess 31 is integrated into the slide rail 32, optimizing the spatial layout. The slide rail 32 itself serves as a local carrier for the locking structure, reducing the number of additional parts and simplifying the structure. Furthermore, the bidirectional abutment of the protrusion 21 and the pivot shaft 4 against the inner walls of both ends of the slide rail 32 provides dual force support when locked, enhancing the structural rigidity during pressing and reducing the risk of deformation of the slide rail 32. In other embodiments, the recess 31 can also be independent of the slide rail 32.

[0054] As a preferred embodiment of this application, such as Figure 3 , Figure 4 , Figure 8 and Figure 10 As shown, the handle 2 is provided with a locking slide 22, which has an opening for the transmission member 3 to slide into. When the transmission member 3 slides into the locking slide 22, the handle 2 performs a locking stroke. When the locking structure is locked, it restricts the movement of the transmission member 3 relative to the locking slide 22. When the transmission member 3 slides out of the locking slide 22, the handle 2 performs an unlocking stroke. Figure 8 The image shows the state where handle 2 has completed its locking stroke and the transmission component 3 has slid into the locking slide 22. Figure 10 The diagram shows the state where the handle 2 has completed its unlocking stroke and the transmission component 3 has slid out of the locking slide 22. In this technical solution, by setting the locking slide 22 on the handle 2, a guiding channel is provided for the cooperation between the handle 2 and the transmission component 3, and also for guiding the handle 2 to complete its locking and unlocking strokes. This allows the transmission component 3 to slide into the locking slide 22 along a preset path to lock with the handle 2, simplifying user operation steps (such as switching states by pushing or pulling in one direction). Simultaneously, the locking slide 22's enveloping effect on the transmission component 3 disperses localized stress during locking, extending the lifespan of the locking structure. After the transmission component 3 slides into the locking slide 22, in addition to the locking structure bearing the force of pressing the handle 2, the inner wall of the locking slide 22 also bears the force of pressing the handle 2. Multiple load-bearing points bear the pressure of the handle 2, reducing the risk of deformation of the handle 2 and the transmission component 3.

[0055] As a preferred embodiment, such as Figure 4 and Figure 8 As shown, a stop wall 23 is provided at the other end of the locking slide 22 opposite to the opening. When the transmission member 3 abuts against the stop wall 23, the locking structure completes the locking. The stop wall 23 provides a clear end point for the sliding stroke of the transmission member 3, ensuring that the locking structure is fully in place and limiting the locking stroke completion state through physical obstruction, avoiding the problem of false locking caused by insufficient sliding. In addition, the stop wall 23 can withstand the reverse impact force in the locked state, further improving the locking stability.

[0056] Furthermore, the locking slide 22 has a straight structure, and its opening is located at one end of the handle 2. In this technical solution, the straight locking slide 22 and the end opening design simplify the processing technology of the handle 2 (e.g., it can be formed in one piece by stamping or injection molding), reduce production costs, and at the same time, the linear movement of the handle 2 and the transmission component 3 conforms to the user's intuitive operating habits, reducing the probability of misoperation. The end opening also facilitates the transmission component 3 to quickly align with the entrance of the locking slide 22. In other embodiments, the locking slide 22 can also be set to other suitable structures according to actual needs, such as an arc-shaped structure, in which case its cooperation process with the transmission component 3 is an arc-shaped movement.

[0057] As a preferred embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the handle 2 has a first connecting piece 24 and a second connecting piece 25 arranged opposite to each other. The pivot shaft 4 passes through and connects the first connecting piece 24 and the second connecting piece 25, forming an opening between the first connecting piece 24 and the second connecting piece 25. During assembly, the transmission component 3 needs to be pre-inserted between the first connecting piece 24 and the second connecting piece 25, so that the slide rail 32 corresponds to the pivot hole 26 on the first connecting piece 24 and the second connecting piece 25 through which the pivot shaft 4 passes. Then, the pivot shaft 4 is inserted into the pivot hole 26 and the slide rail 32 and axially limited. In this technical solution, the symmetrical arrangement of the first connecting piece 24 and the second connecting piece 25 provides double-sided support for the pivot shaft 4, improving the structural stability of the pivot shaft 4 and preventing shaft deflection caused by unilateral force. Simultaneously, the opening between the first connecting piece 24 and the second connecting piece 25 forms a clearance space, ensuring that the transmission component 3 is not obstructed when sliding into the locking slide 22, thus improving the assembly error tolerance.

[0058] As a preferred embodiment of this application, such as Figure 1 , Figure 5 and Figure 11 As shown, the pivot shaft 4 is located at the first end of the handle 2, and the second end of the handle 2 is provided with a first locking part 27. The base 12 of the body 1 is provided with a second locking part 11. When the handle 2 rotates in the first direction to perform the storage stroke, the first locking part 27 and the second locking part 11 are locked, thereby restricting the handle 2 from rotating in the second direction opposite to the first direction. Figure 1The diagram shows the locked state of the first locking part 27 and the second locking part 11. In this technical solution, the cooperation of the first locking part 27 and the second locking part 11 achieves a self-locking function in the retracted state of the handle 2. When the handle 2 is rotated to the retracted position in the first direction, the first locking part 27 and the second locking part 11 automatically lock, preventing the handle 2 from accidentally unfolding due to vibration or collision. Simultaneously, it limits the degree of freedom of reverse rotation, ensuring a secure and reliable retracted state, and achieving fixation without additional operation. This application does not limit the locking method of the first locking part 27 and the second locking part 11; for example, snap-fit, magnetic attraction, plug-in, etc., can be used.

[0059] In a preferred embodiment, the second locking part 11 is provided with a locking cavity 111 and a buckle 112 located within the locking cavity 111. The first locking part 27 is provided with a groove 271 adapted to the buckle 112. The second end of the handle 2 enters the locking cavity 111, causing the buckle 112 to engage with the groove 271, thereby confining the second end within the locking cavity 111. In this technical solution, the nested engagement of the locking cavity 111 and the groove 271 achieves multiple locking through cavity enclosure and buckle 112 embedding, significantly improving the anti-disengagement capability in the stored state. Furthermore, the fit between the buckle 112 and the groove 271 allows for a certain amount of deformation, reducing wear during repeated opening and closing, and balancing locking strength and service life.
