Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of pool sewage suction, and in particular to a handheld cleaning device for a pool. Background Art

[0002] Water filtration is an essential component of pool cleaning and maintenance equipment, and its performance is directly related to the cleanliness of the pool water and the efficiency of the equipment. Water filtration systems are typically equipped with a filter assembly. However, in actual use, pool water often contains impurities such as particles of varying sizes, algae, and hair. These impurities accumulate and adhere to the filter as they are drawn through the filter, causing the filter aperture to gradually decrease, filtration efficiency to gradually decrease, and even complete clogging, affecting the normal operation of the equipment and forcing users to frequently stop the machine to inspect and clean the filter.

[0003] In the related art, the filter assembly is mostly a single filter or filter cotton. When the filter or filter cotton is clogged, the dirt suction capacity of the flow channel will be reduced, the flow rate will be lost, and the cleaning device will lose its dirt suction capacity.

[0025] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions in this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0026] Water filtration is an essential component of pool cleaning and maintenance equipment, and its performance is directly related to the cleanliness of the pool water and the efficiency of the equipment. Water filtration systems are typically equipped with a filter assembly. However, in actual use, pool water often contains impurities such as particles of varying sizes, algae, hair, and leaves. These impurities are drawn into and flow through the filter, where they gradually accumulate and adhere to the filter. This causes the filter aperture to gradually decrease, filtration efficiency to gradually decrease, and even complete clogging, affecting the normal operation of the equipment and forcing users to frequently stop the machine to inspect and clean the filter.

[0027] In the related art, the filter assembly is mostly a single filter or filter cotton. When the filter or filter cotton is clogged, the dirt suction capacity of the flow channel will be reduced, the flow rate will be lost, and the cleaning device will lose its dirt suction capacity.

[0028] In view of this, the present application provides a handheld pool cleaning device. It is understood that the handheld pool cleaning device can be used to clean a pool while held by a user. The pool is, for example, a pool-shaped structure. The pool-shaped structure can be a swimming pool, a reservoir, a spa pool, a water tank, a water storage tank, or the like.

[0029] The handheld cleaning device includes a water pump, a filter device and a main body, wherein the filter device is detachably connected to the main body, wherein the filter device includes a shell and a filter at least partially arranged inside the shell, a water inlet is formed at the bottom of the shell, and an opening is formed at the top of the shell, the opening is used to install the filter, the filter and the shell form a first water flow channel and a second water flow channel, under the action of the water pump, the water flow entering the water inlet can pass through the first water flow channel in part, and the other part can pass through the second water flow channel.

[0030] Specifically, in this application, the filter device in the handheld cleaning device is detachably connected to the main body, allowing users to quickly and easily replace or clean the filter device. This allows for maintenance of key components without disassembling the entire handheld cleaning device, significantly reducing maintenance costs and time. Furthermore, in the filter device, the filter and the housing form a first water flow channel and a second water flow channel. This allows the filter device to maintain a certain degree of suction and filtration even if impurities clog one of the water flow channels (e.g., the second water flow channel), reducing the frequency of cleaning or replacement of the filter device and improving the user experience.

[0031] The various embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0032] First refer to Figure 1 and Figure 2 Provide explanation. Figure 1 A structural schematic diagram of an embodiment of a handheld cleaning device for a pool according to the present application is shown. Figure 2 FIG2 is a schematic structural diagram of another embodiment of a handheld pool cleaning device according to the present application. The handheld pool cleaning device includes a water pump 10, a filter device 20, and a main body 30. The water pump 10 and the filter device 20 can both be disposed within the main body 30.

[0033] In one embodiment, both the water pump 10 and the filter device 20 are at least partially disposed outside of and connected to the main body 30. In another embodiment, one of the water pump 10 and the filter device 20 is disposed within the main body 30, while the other is at least partially disposed outside of and connected to the main body 30. Those skilled in the art may selectively configure the positional and connection relationships among the water pump, the filter device, and the main body based on the principles of this application, as long as the technical principles of this application can be implemented.

[0034] The water pump 10 is used to draw water to be filtered from the pool into the filter device 20 for filtration, thereby removing impurities in the pool and achieving the effect of cleaning the pool. The main body 30 can support and protect the water pump 10 and the filter device 20.

[0035] In the embodiment of the present application, the filter device 20 is detachably connected to the main body 30. The filter device 20 includes a housing 21 and a filter 22 at least partially disposed within the housing 21. The bottom of the housing 21 is formed with a water inlet 23, and the top of the housing 21 is formed with an opening 24 for receiving the filter 22. The filter 22 and the housing 21 form a first water flow channel and a second water flow channel. Under the action of the water pump 10, the water entering the water inlet 23 can partially pass through the first water flow channel and the other part can pass through the second water flow channel.

[0036] The housing 21 can support and protect the filter device 20 and other components inside the housing 21 .

[0037] Refer to the following Figure 3 The embodiments of the present application are further described.

[0038] First, see the Figure 3 The three solid arrows (hereinafter referred to as "solid arrows") shown below illustrate the common waterway. After being drawn into housing 21 through water inlet 23 by a water pump, pool water flows along the common waterway toward the filter. Specifically, the water flows along the common waterway, sequentially through water inlet 23, one-way valve 231, and the space between first filter 221 and one-way valve 231, before reaching the outside of filter 22.

[0039] See also Figure 3 The six dotted arrows (hereinafter referred to as "dashed arrows") shown in the middle and upper portions of FIG. illustrate the first water flow path. Water flows along the first water flow path, sequentially passing through the first filter 221 and the inner filter layer 2221 of the second filter 222, before reaching the drain outlet 25.

[0040] See also Figure 3 The six arrows (hereinafter referred to as "dashed and solid arrows") shown in the middle and upper portions of the figure illustrate the second water flow path. Water flows along this second water flow path, sequentially passing through the outer filter layer 2222 of the second filter 222 and the space between the outer filter layer 2222 and the inner filter layer 2221, before reaching the drain outlet 25.

[0041] Examples of the solid arrows, dashed arrows, and dashed-solid arrows mentioned above are shown in Table 1 below:

[0042]

[0043] Table 1

[0044] It can be seen from this that the water flow can flow through the filter 22 through the two water flow channels (ie, the first water flow channel and the second water flow channel) respectively, and thus be filtered by the filter 22.

[0045] When the filter 22 is operating normally (i.e., the filter 22 is not clogged), water flows through both water flow channels. In practice, in this state, water flowing through the one-way valve 231 is primarily filtered through the second water flow channel, i.e., primarily filtered through the outer filter layer 2222 of the second filter 222. However, when the filter 22 becomes clogged to some extent, for example, when the outer filter layer 2222 of the second filter 222 is clogged, the second water flow channel (or a portion of the second water flow channel) becomes clogged (or clogged to a certain extent), preventing water from flowing through the second water flow channel (or reducing the flow rate or flow rate of water through the second water flow channel). In this case, water can still flow through the first water flow channel (in other words, is primarily filtered through the first water flow channel), thereby fulfilling the filtering function of the filter 22.

[0046] Therefore, the filter 22 and the housing 21 form a first water flow channel and a second water flow channel. Even if impurities clog one of the water flow channels, the filter 22 still maintains a certain degree of suction and filtration capabilities, reducing the frequency of cleaning or replacement of the filter device 20 and improving the user experience. For example, when the second water flow channel is clogged or reaches a certain degree of clogging, water will flow along the first water flow channel and through the filter (or at least a portion of the filter), thereby achieving a certain degree of suction and filtration capabilities.

[0047] Furthermore, the filter 22 is detachably connected to the top opening 24. The manner in which the filter 22 is detachably connected to the top opening 24 includes, but is not limited to, a snap connection, a threaded connection, and the like.

[0048] Specifically, the filter 22 is detachably connected to the top opening 24 , so that when the filter 22 is clogged by dirt, only the filter 22 needs to be removed from the filter device 20 for cleaning or replacement, further reducing maintenance costs and time.

[0049] Furthermore, the filter 22 includes a first filter 221 and a second filter 222. The first water flow channel passes through the first filter 221, and the second water flow channel passes through the second filter 222. In the present application, the scheme of providing two filters (i.e., the first filter 221 and the second filter 222) can improve space utilization; and the first water flow channel passes through the first filter 221, and the second water flow channel passes through the second filter 222. In this way, impurities in the water flowing through the first water flow channel and the second water flow channel can be filtered by the filter 22, thereby improving the decontamination ability of the filter device 20; and when one of the two water flow channels is blocked (for example, the second water flow channel is blocked), the filter device 20 can still filter the water flow through the other water flow channel, so that the handheld cleaning device still has a certain degree of dirt suction and filtering ability.

[0050] Furthermore, the first filter 221 and the second filter 222 are detachably connected. Specifically, the detachable connection between the first filter 221 and the second filter 222 facilitates the user to clean and replace the first filter 221 and the second filter 222 separately, and facilitates the reuse of the first filter 221 and the second filter 222. In addition, the first filter 221 and the second filter 222 are interchangeable, which facilitates user selection.

[0051] The manner in which the first filter 221 and the second filter 222 are detachably connected includes but is not limited to a snap connection, a threaded connection, and the like.

[0052] Furthermore, the second filter 222 is detachably connected to the top opening 24 , and a drain outlet 25 is formed on the top of the second filter 222 . When the second filter 222 is connected to the top opening 24 , the water flow in the first water flow channel and the water flow in the second water flow channel can only flow out through the drain outlet 25 .

[0053] Specifically, a detachable connection is provided between the second filter 222 and the top opening 24 , so that when the second filter 222 is clogged or clogged to a certain extent, it is convenient for a user to remove the second filter 222 from the top opening 24 .

[0054] The materials of the first filter 221 and the second filter 222 include but are not limited to filter mesh, filter cotton, activated carbon, polyester fiber, etc. The materials are designed according to actual needs.

[0055] In the embodiment of the present application, the first filter 221 includes a filter mesh, and the second filter 222 includes a filter mesh and filter cotton.

[0056] Furthermore, the first filter 221 is located below the second filter 222 , and the water flowing out of the first water flow channel from the first filter 221 can enter the second filter 222 for secondary filtration.

[0057] It can be understood that since the first filter 221 is located below the second filter 222 and the water pump is located above the second filter 222, a portion of the water flow entering the filter device 20 from the water inlet 23 passes through the first filter 221 and then passes through the second filter 222. This portion of the water flow is filtered twice (i.e., filtered once by the first filter 221 and filtered another time by the second filter 222), thereby improving the filtering effect on this portion of the water flow.

[0058] Furthermore, the second filter 222 includes an inner filter layer 2221 located inside and an outer filter layer 2222 located outside. The water flowing out of the first filter 221 passes through the inner filter layer 2221 for secondary filtration, and the water in the second water flow channel passes through the outer filter layer 2222 for primary filtration.

[0059] like Figure 3 As shown in FIG, the water flow in the first water flow channel first passes through the first filter 221 and then passes upward through the inner filter layer 2221 in the second filter 222 (see FIG. Figure 3 ), and further flows toward the top opening 24 (see Figure 3 The water flow in the second water flow channel only passes through the outer filter layer 2222 in the second filter 222 (see Figure 3 ), and flows along the space between the outer filter layer 2222 and the inner filter layer 2221 toward the top opening 24 (see Figure 3 (dashed and solid arrows in ).

[0060] Specifically, the arrangement of multiple filters (including the first filter 221, the inner filter layer 2221, and the outer filter layer 2222) can fully utilize the space to improve the utilization rate of the filter arrangement, thereby improving the filtering ability of the water flow.

[0061] Further, see Figure 4 The second filter 222 further includes a bracket 2223, which is disposed between the inner filter layer 2221 and the outer filter layer 2222. For example, the bracket 2223 surrounds the inner filter layer 2221, and the outer filter layer 2222 surrounds the bracket 2223. The bracket 2223 is used to install and fix the inner filter layer 2221 and the outer filter layer 2222. It will be understood by those skilled in the art that Figure 4The parameters such as the position, length and shape of the bracket 2223 shown in the figure are only exemplary and are not intended to limit the parameters such as the position, length and shape of the bracket 2223 of the present application. Those skilled in the art can selectively set the various parameters of the bracket 2223 according to actual needs, as long as the technical principles of the present application can be implemented.

[0062] Furthermore, both the first filter 221 and the inner filter layer 2221 include filter meshes, and the inner filter layer 2221 is cylindrical in shape. An opening is provided at the bottom of the cylindrical filter layer for water in the first water flow channel to flow in.

[0063] It can be understood that the inner filter layer 2221 is designed to be cylindrical. After the water flow in the first water flow channel flows into the inner filter layer 2221 through the bottom opening, the cylindrical inner filter layer 2221 can achieve secondary filtration of the water flow in all directions, thereby improving the filtering effect of the water flow.

[0064] The specifications of the filter mesh forming the first filter 221 and the specifications of the filter mesh forming the inner filter layer 2221 can be selected according to the requirements of the filtering level / filtering effect.

[0065] In one embodiment, the filtration accuracy of the first filter 221 is lower than that of the second filter 222. For example, the filtration accuracy of the first filter 221 is lower than that of the inner filter layer 2221 and the outer filter layer 2222 of the second filter 222. Therefore, the second filter 222 can effectively filter the water, regardless of whether the water flows through the first water flow channel or the second water flow channel.

[0066] In one embodiment, the filter forming the first filter 221 is a 40-mesh nylon filter, and the filter forming the inner filter layer 2221 is a 180-mesh nylon filter. The 40-mesh nylon filter can coarsely filter dirt in the water flow, preventing large dirt particles from clogging the second filter 222. After the water flowing out of the 40-mesh nylon filter is filtered through the 180-mesh nylon filter for a second time, it can achieve a filtration effect of 100 μm.

[0067] Furthermore, the outer filter layer 2222 of the second filter 222 includes filter cotton. It is understood that since the water in the second water flow channel only flows through the outer filter layer 2222 for filtering once, the use of filter cotton as the outer filter layer 2222 can improve the filtration level of the water in the second water flow channel due to its high filtration accuracy.

[0068] It is understandable that under the same dirt level, although the filtering accuracy of the filter cotton is higher and can improve the filtering level, at the same time, the filter cotton will be more easily clogged; and the filtering accuracy of the 40-mesh nylon filter screen and the 180-mesh nylon filter screen is lower than that of the filter cotton, so the nylon filter screen is not easily clogged. Therefore, when the filter cotton is clogged, the water flow can also pass through the 40-mesh nylon filter screen and the 180-mesh nylon filter screen to achieve a certain dirt absorption capacity and filtering effect, thereby reducing the frequency of users cleaning or replacing the filter device 20 and improving the user experience.

[0069] Furthermore, the water inlet 23 includes a one-way valve 231. When the water pump 10 performs a cleaning task, water flows under the suction of the water pump and pushes the one-way valve 231 upward, thereby opening the one-way valve 231.

[0070] Specifically, the one-way valve 231 can automatically prevent water from flowing out of the water inlet 23 in the reverse direction. When water flows into the filter device 20 from the water inlet 23, the one-way valve 231 automatically opens to allow water to flow through (such as Figure 3 and when the water flow attempts to flow in the reverse direction, the one-way valve 231 is closed to prevent the water flow from flowing back, effectively preventing the water flow and dirt entering the filter device 20 from flowing back out, thereby ensuring the stability and continuity of the cleaning process.

[0071] The handheld cleaning device further includes a suction head 40, through which water from the pool enters the filter device 20 for filtration. The suction head 40 is rotatably connected to the main body 30. In one embodiment, the suction head 40 is connected to the main body 30 via a universal joint to enable flexible suction in all directions. In other embodiments, the suction head 40 may be connected to the main body 30 via a ball hinge, a multi-jointed arm, or the like.

[0072] Specifically, the suction head 40 is rotatably connected to the main body 30, so that the suction head 40 can rotate within a certain angle, thereby improving the flexibility of the suction head 40 in the suction direction, improving the cleaning efficiency and effect, and enabling it to adapt to more complex terrains and cleaning needs. At the same time, it can improve the hand feel comfort during operation and reduce the operator's fatigue.

[0073] Furthermore, a counterweight is provided within the suction head 40. The counterweight can be fixedly mounted within the suction head 40 by providing an internal mounting groove or a fixing frame. The shape of the counterweight is adapted to the mounting space. Optionally, the counterweight can be designed into a regular geometric shape, such as a cube, cuboid, or cylinder, for ease of processing and installation. The provision of the counterweight increases the weight of the suction head 40, allowing it to remain firmly attached to the ground, preventing it from floating upon entry into water, and improving the suction effect.

[0074] Specifically, the handheld pool cleaning device generates suction through a water pump 10, driving the water to be filtered in the pool from the suction head 40 into the filter device 20. The filter device 20 filters the sucked water to be filtered, and the filtered clean water flow is finally discharged through the drain port 25, thereby achieving purification and circulation of the pool water quality.

[0075] Furthermore, the water flow path in the filter device 20 is as follows Figure 3 As shown, the paths of the dashed and real arrows represent the second water flow channel, and the path of the dotted arrow represents the first water flow channel. When the outer filter layer 2222 is blocked by the dirty water in the second water flow channel or is at a certain degree of blockage, the water will flow along the first water flow channel shown by the dotted arrow.
