[0026] like Figures 1 to 4 As shown, according to an embodiment of this application, a pool skimmer is provided, which includes a mounting assembly 10 and a filter assembly 20. In some embodiments, the mounting assembly 10 is used to install the pool skimmer on the side wall of the pool, while the filter assembly 20 extends into the water to effectively collect and filter floating debris on the water surface.

[0027] The mounting assembly 10 includes a top 101 and a side 102. A first end of the top 101 is connected to a first end of the side 102, and the top 101 and side 102 form an approximately 90-degree angle. The filter assembly 20 is connected to a second end of the side 102. The top 101 and side 102 can be an integrated structure as shown in the figure; or they can be separate structures, combined using screws, clips, adhesives, or other connecting methods, to facilitate production assembly and subsequent maintenance.

[0028] The pool skimmer integrates water temperature monitoring and real-time display functions to enhance the product's intelligence and user experience. The pool skimmer also includes at least one temperature sensor, a circuit board 1031 mounted on the top 101, a display screen 1032, and a battery 1038. The circuit board 1031 has temperature monitoring and display circuitry. The display screen 1032, at least one temperature sensor, and battery 1038 are all electrically connected to the circuit board 1031. The at least one temperature sensor includes a first temperature sensor 1035, which is located at the second end of the side 102 and electrically connected to the circuit board 1031 via a wire.

[0029] The display screen 1032 is used to display the temperature value collected by at least one temperature sensor. In use, the pool skimmer's mounting assembly 10 is hung on the side wall of the pool, ensuring that the first temperature sensor 1035, located on the side 102, is fully immersed in the pool water. At this time, the circuitry on the circuit board 1031 can obtain the water temperature collected by the first temperature sensor 1035 in real time, and the current pool water temperature can be viewed at any time through the display screen 1032, allowing the user to monitor the pool water temperature without additional temperature measuring tools.

[0030] More specifically, such as Figure 2 and Figure 4As shown, the top 101 includes an upper housing 1012 and a lower housing 1011. The upper housing 1012 is provided with a window 1015, which is aligned with the display screen 1032, allowing users to clearly read the displayed content through the window 1015.

[0031] The first end of the side portion 102 is connected to the lower housing 1011. The circuit board 1031, the display screen 1032, and the battery are located between the upper housing 1012 and the lower housing 1011. The circuit board 1031 is fixed to the lower housing 1011, the display screen 1032 is mounted on the side of the circuit board 1031 facing the upper housing 1012, and the battery 1038 is located on the side of the circuit board 1031 facing away from the upper housing 1012.

[0032] In some embodiments, the battery 1038 described above includes a replaceable disposable battery or a rechargeable battery.

[0033] In some embodiments, the circuit board 1031 is also provided with a charging circuit, which can be connected to an external power adapter and charge the rechargeable battery.

[0034] In other embodiments, such as Figure 4 As shown, the pool skimmer is also equipped with a solar panel 1034, which is installed on the outside of the upper housing 1012. The solar panel 1034 is electrically connected to the circuit board 1031 and can charge the rechargeable battery. The solar power supply solution extends the equipment's operating time and reduces maintenance costs.

[0035] In some embodiments, at least one button is electrically connected to the circuit board 1031, and the at least one button includes, for example, Figure 4 The temperature scale button 1033 is shown in the figure. The temperature display of this application includes two temperature measurement units: Celsius and Fahrenheit, to suit the different user preferences. Triggering the temperature scale button 1033 switches the temperature measurement unit and corresponding temperature value on the display screen 1032. Additionally, in some embodiments, the upper housing 1012 also has a button 1037 corresponding to the temperature scale button 1033, and this button 1037 is aligned with the temperature scale button 1033.

[0036] In some embodiments, such as Figure 4As shown, to facilitate viewing the content on the display screen 1032 at night, the display screen 1032 is equipped with a backlight 1039, which is mounted on the circuit board 1031. The backlight 1039 facilitates viewing the information on the display screen at night or in low light conditions, enhancing the convenience of all-weather use of the device. Of course, some display screens 1032 have built-in backlight functions, and no specific limitation is made here. In addition, regarding the control method of the backlight 1039, a photosensitive element (such as a photoresistor) electrically connected to the circuit board 1031 can be installed to sense the ambient light intensity and automatically turn on the backlight 1039 at night or in low light conditions; or, the switching time can be set (manually set or preset in the chip) on the circuit board 1031 to manage the on-time of the backlight 1039; or, at least one of the above-mentioned buttons includes a light button, and the backlight 1039 is controlled by the light button; or, the backlight 1039 is always kept on.

[0037] In some embodiments, the circuit board 1031 is also electrically connected to a second temperature sensor 1036 for acquiring the ambient temperature, and the display screen 1032 also displays the temperature value acquired by the second temperature sensor 1036. Compared to the outdoor temperature reported by the city or region, the temperature acquired by the second temperature sensor 1036 is closer to the ambient temperature of the swimming pool.

[0038] The water volume of the pool affects the water level, and the upper edge 2016 of the filter assembly 20 needs to be substantially flush with the water surface. Therefore, in some embodiments, such as Figure 2 and Figure 3 As shown, the side 102 of the mounting assembly 10 is provided with a slide rod 104, and the filter assembly 20 is mounted on the slide rod 104 and can be adjusted along the length of the slide rod 104. In this way, the position of the filter assembly 20 on the slide rod 104 can be adjusted according to the pool water level so that after the pool skimmer is installed, the upper edge 2016 of the filter assembly 20 can remain basically flush with the pool water surface. Specifically, as... Figure 2 and Figure 8As shown, the filter assembly 20 has a connecting end 2012 on its outer side, and the connecting end 2012 has a sliding hole 2013. The slide rod 104 can be selectively inserted into the sliding hole 2013 and slidably connected thereto. The connecting end 2012 has an externally threaded tube 2014, which communicates with the sliding hole 2013. The externally threaded tube 2014 is connected to a knob 2015 for fastening. The knob 2015 has an internal thread and an inner core that threadedly engage with the externally threaded tube 2014. When the knob 2015 is threadedly connected to the externally threaded tube 2014, the inner core of the knob 2015 can be inserted into the externally threaded tube 2014. Rotating the knob 2015 causes the end of the inner core to move closer to the sliding hole 2013 and abut against the slide rod 104 inside the sliding hole 2013, thereby fixing the filter assembly 20 onto the hanging assembly 10. The above structure allows the filter assembly 20 to be selectively adjusted along the length of the slide bar, ensuring that it is always in the optimal working position, thus improving skimming efficiency and equipment applicability.

[0039] In addition, in some embodiments, the side wall of the connecting end 2012 is provided with a through hole with internal threads, which communicates with the sliding hole 2013. The knob has an inner core with external threads, and the inner core is threadedly connected to the through hole. Rotating the knob allows the end of the inner core to approach the sliding hole 2013 and abut against the slide rod 104 inside the sliding hole 2013, thus achieving a fixed connection between the filter assembly 20 and the hanging assembly 10. Of course, other fixed connection methods can also be used, and no specific limitations are made here.

[0040] like Figure 2 and Figure 5 As shown, in some embodiments, the slide bar 104 is detachably connected to the side portion 102 of the hanging assembly 10. This is to allow for the adaptation of slide bars 104 of different lengths or types to different pool skimmer models or requirements. In this embodiment, the second end of the side portion 102 is provided with a insertion slot 1021, and the first end of the slide bar 104 is a insertion end 1041. The insertion end 1041 of the slide bar 104 can be selectively inserted into the insertion slot 1021 and engaged with it to restrict the slide bar 104 to the side portion 102 of the hanging assembly 10.

[0041] like Figure 3 and Figure 5 As shown, in some embodiments, the second end of the slide bar 104 is provided with a component slot 1042, which is used to accommodate the first temperature sensor 1035. The side of the slide bar 104 is also provided with a wire slot 1043, which is used to accommodate the wires that electrically connect the first temperature sensor 1035 to the circuit board 1031.

[0042] like Figure 5 and Figure 6As shown, in some embodiments, the pool skimmer also includes a first fixing component 40, which includes a slider 401 and a support rod 402. The slider 401 is fixedly connected to the support rod 402, and the included angle between the slider 401 and the support rod 402 is approximately 90 degrees. The slider 401 has a first threaded hole 4011 on both its first and second sides, wherein the first and second sides are opposite in direction, and the axial direction of the first threaded hole 4011 is perpendicular to the length direction of the slider 401 and the length direction of the support rod 402. The support rod 402 has at least one second threaded hole 4021, which penetrates the support rod 402 and has an axial direction approximately the same as the length direction of the slider 401. The top 101 of the mounting component 10 has a sliding groove 1013, which extends along the length direction of the top 101 and is approximately perpendicular to the length direction of the side portion 102. The first and second sidewalls of the sliding groove 1013 are each provided with a slot 1014, which extends along the length of the top 101. The first and second sidewalls are located on opposite sides of the top 101. The slider 401 can selectively slide within the sliding groove 1013 to adjust the distance between the support rod 402 and the pool sidewall.

[0043] The first fixing component 40 also includes a first fastener 403, which has a handle and a screw. The screw of the first fastener 403 passes through the slot 1014 and connects to the first threaded hole 4011 of the slider 401. Rotating the first fastener 403 causes the handle to abut against the top 101 to fix the slider 401 to the top 101 of the mounting component 10.

[0044] The first fixing component 40 also includes a second fastener 404, which has a handle and a screw, with the handle located at the first end of the screw. The screw of the second fastener 404 is threaded into a second threaded hole 4021, and the second end of the screw can be inserted into the second threaded hole 4021 from the side facing away from the side 102 and exit from the second threaded hole 4021 towards the side 102. Continuing to rotate the second fastener 404 can move the second end of the screw closer to or away from the side 102 of the mounting component 10.

[0045] When fixing the pool skimmer, hang the mounting assembly 10 in a suitable position in the pool, move the slider 401 to adjust the distance between the support rod 402 and the pool side wall, and then tighten the slider 401. Then rotate the second fastener 404 so that the screw of the second fastener 404 approaches the pool side wall until the second end of the screw abuts against the pool side wall and is tightened.

[0046] In some embodiments, the second end of the screw of the second fastener 404 is provided with a rotatably connected abutment plate 405. The abutment plate 405 can increase the contact area between the second fastener 404 and the pool sidewall, preventing damage to the pool due to excessive force concentration during the tightening process. Furthermore, in some embodiments, both the side of the abutment plate 405 facing the side portion 102 and the side of the side portion 102 facing the abutment plate 405 are provided with anti-slip textures. These anti-slip textures can effectively increase the friction of the contact surface, preventing displacement of the device under water flow impact or vibration, thereby improving the stability of the pool skimmer fixed to the pool.

[0047] In other embodiments, such as Figure 7 As shown, this application provides a second fixing component, which replaces the support rod 402 and the second fastener 404 in the first fixing component 40 with a hook 406. The end of the hook 406 facing away from the slider 401 is bent towards the side 102, so that the top 101, side 102, and hook 406 of the hanging component 10 together form a snap-fit ​​structure. In application, the hanging component 10 can be hung in a suitable position in the pool, and the slider 401 can be moved to adjust the distance between the hook 406 and the pool sidewall. Once the hook 406 is tightly fitted against the pool sidewall, the slider 401 is locked in place by the first fastener 403, thus completing the quick installation and fixing of the skimmer.

[0048] like Figures 8 to 11 As shown, this application also provides a filter assembly 20, which includes an outer cylinder 201 with a cavity 2011, and the aforementioned connecting end 2012 is disposed on the outside of the outer cylinder 201. The bottom of the outer cylinder 201 is provided with a water outlet end, which communicates with the cavity 2011. In this embodiment, the water outlet end is a water outlet pipe 206. The cavity 2011 has an upper opening, and a filter is disposed within the cavity 2011. In an embodiment of this application, the filter is a funnel cylinder 202, which has a filter cavity 2021. The sidewalls and bottom of the funnel cylinder 202 are provided with a plurality of water-permeable holes 2023, which can filter out floating matter and particulate impurities in the pool water. The top of the funnel cylinder 202 is provided with a rotatably connected handle 2022. A float 204 is disposed above the cavity 2011, and the float 204 includes a funnel-shaped water inlet pipe 2041 and a cylinder body 2042. The funnel-shaped inlet pipe 2041 not only optimizes the water flow path and reduces resistance, but also increases the local flow velocity through its gradually narrowing diameter, thereby enhancing suction and improving the efficiency of collecting floating debris. The inlet pipe 2041 includes a first end 2041a facing away from the outer cylinder 201 and a second end 2041b in the opposite direction. The inlet pipe 2041 extends smoothly downward from the first end 2041a to the second end 2041b, with its diameter gradually decreasing.

[0049] The cylinder body 2042 is located on the side of the inlet pipe 2041 facing the outer cylinder 201, and extends downward from the middle of the first end 2041a and the second end 2041b of the inlet pipe 2041. The cylinder body 2042 of the float 204 is inserted between the outer wall of the drain cylinder 202 and the inner wall of the outer cylinder 201, and can move along the axial direction of the outer cylinder 201.

[0050] To improve filtration efficiency, in some embodiments, such as Figure 12 As shown, the inlet pipe 2041 is provided with multiple upwardly protruding and unidirectionally inclined guide strips 2044. These guide strips 2044 are evenly distributed circumferentially along the inlet pipe 2041 and extend tangentially from the radial direction, causing the water flowing into the float 204 to generate a tangential velocity component. The multiple guide strips 2044 guide the pool water flowing through the inlet pipe 2041 to form a vortex, enhancing the suction of the filter assembly 20. The vortex flow field formed by the multiple guide strips 2044 can effectively separate and concentrate impurities, preventing floating matter from escaping and significantly improving the skimming ability of the filter assembly 20.

[0051] In some embodiments, the filter includes filter cotton, which is laid at the bottom of the cavity 2011, and can also achieve the filtration effect. Using replaceable filter cotton as the filter medium enhances the ability of the filter assembly 20 to capture fine pollutants; the filter cotton can effectively intercept fine particles, oil, and suspended impurities, preventing them from entering the water pump system and causing blockage or damage. Users can periodically replace or clean the filter cotton according to water quality conditions, achieving flexible adaptation to different filtration precision requirements.

[0052] See also Figure 8 and Figure 10 As shown, a detachable first retaining ring 203 is installed on the upper edge 2016 of the outer cylinder 201. The first retaining ring 203 has an annular groove 2031 on the side facing the outer cylinder 201, which is inserted into the upper edge 2016 of the outer cylinder 201. A second retaining ring 205 is provided at the end of the cylinder body 2042 of the float 204. The outer diameter of the second retaining ring 205 is smaller than the inner diameter of the cavity 2011 of the outer cylinder 201, but larger than the inner diameter of the first retaining ring 203; the inner diameter of the first retaining ring 203 is larger than the outer diameter of the cylinder body 2042. The float 204 can move axially along the outer cylinder 201, but is restricted by the first retaining ring 203 and cannot detach from the outer cylinder 201. Through the cooperation of the first retaining ring 203 and the second retaining ring 205, reliable axial positioning of the float 204 is achieved, ensuring its floating function with the water level while preventing the float from falling off due to water flow impact.

[0053] In some embodiments, the inner wall of the annular groove 2031 is connected to the upper edge 2016 of the outer cylinder 201 by an interference fit, so that the first retaining ring 203 is firmly fixed to the outer cylinder 201 and is not easy to loosen or fall off. Alternatively, in other embodiments, the outer wall of the outer cylinder 201 is provided with a third retaining ring 2017, which is adjacent to the upper edge 2016 of the outer cylinder 201. A wrench 2032 is provided on the outer side of the first retaining ring 203, and a buckle 2033 is provided on the side of the wrench 2032 facing the outer cylinder 201. When the first retaining ring 203 is installed on the upper edge 2016 of the outer cylinder 201, the buckle 2033 engages with the third retaining ring 2017 to restrict the first retaining ring 203 to the outer cylinder 201. If disassembly is required, simply turn the wrench 2032 in the direction away from the outer cylinder 201 to disengage the buckle 2033 from the third retaining ring 2017, thereby releasing the first retaining ring 203 from its restriction on the outer cylinder 201.

[0054] In some embodiments, the second retaining ring 205 is detachably connected to the cylinder body 2042. For example, the second retaining ring 205 has an annular groove on the side facing the cylinder body 2042, and the inner wall of the groove is interference-fitted with the cylinder body 2042 to fix the second retaining ring 205 onto the cylinder body 2042. Alternatively, the second retaining ring 205 is directly sleeved on the outer side of the cylinder body 2042, and the limiting is achieved by friction or elastic pre-tightening.

[0055] In some embodiments, the bottom of the cavity 2011 is provided with four upwardly extending support plates 2018, which are evenly distributed circumferentially along the bottom. The support plates 2018 raise the bottom of the funnel 202, keeping it at a certain distance from the bottom of the cavity 2011, thus forming a flow guiding gap.

[0056] like Figure 13 and Figure 14 As shown, most of the filter assembly 20 is immersed in the pool water, ensuring that the first end of the inlet pipe 2041 (i.e., the top surface of the float 204) is basically flush with the water surface 80. In this embodiment, the outlet pipe 206 of the outer cylinder 201 is directly connected to the inlet end 501 of the water pump 50. In other embodiments, the outlet pipe 206 at the bottom of the outer cylinder 201 can also be connected to the inlet end 501 of the water pump 50 via a water pipe. This application does not limit the connection method between the outlet pipe 206 and the water pump 50. When the water pump 50 is started, the floating objects on the water surface 80 can flow into the cavity 2011 of the outer cylinder 201 along with the pool water from the inlet pipe 2041, and after being filtered by the filter cylinder 202, they enter the water pump 50 from the outlet pipe 206 at the bottom of the outer cylinder 201, and finally are discharged into the pool from the outlet end 502 of the water pump 50, completing one cycle of filtration.

[0057] in, Figure 13 and Figure 14 These are the two working conditions of float 204 under two water level states: Figure 13This is a schematic diagram showing the state when the water level is low. As can be seen from the diagram, the inlet pipe 2041 of the float 204 is basically in contact with the top of the first retaining ring 203. And... Figure 14 This is a schematic diagram showing the state when the water level is high. Figure 15 As can be seen, the second retaining ring 205 of the float 204 is basically in contact with the first retaining ring 203. Within this range, the float 204 can float freely with changes in water level, always keeping the first end of the inlet pipe 2041 basically flush with the water surface 80. Furthermore, the applicability of the pool skimmer can be expanded by adjusting the position of the filter assembly 20 on the slide rod 104. If necessary, the slide rod 104 of the required length can be replaced to accommodate more pool models or depths.

[0058] In some embodiments, to ensure that as much of the pool water flowing through the inlet pipe 2041 enters the filter cylinder as possible, the inner diameter of the second end of the inlet pipe 2041 can be designed to be less than or equal to the inner diameter of the opening of the filter cylinder 202. This size-matching design ensures that water flows smoothly from the inlet pipe 2041 into the filter cylinder 202, improving water flow efficiency and impurity capture rate, and optimizing overall filtration performance.

[0059] like Figure 8 , Figure 10 and Figure 13 As shown, in some embodiments, the first end 2041a of the inlet pipe 2041 is provided with an outwardly and downwardly extending eave 2043, and the surface of the eave 2043 smoothly transitions with the surface of the inlet pipe 2041. The guiding slope formed by the eave 2043 facilitates the smooth flow of pool water and floating objects on the water surface 80 into the inlet pipe 2041. In addition, an annular chamber is formed between the eave 2043 and the inlet pipe 2041, which can store some air to provide additional buoyancy, which helps to maintain the balance and stability of the float 204.

[0060] This application also provides some application scenarios, such as: like Figure 16 and Figure 17 As shown, the skimmer 61 of this application is applied to a support pool 71. In this application scenario, the skimmer 61 is equipped with a first fixing component and is fixed to the upper edge of the support pool 71 by the first fixing component. Figure 16 In this scenario, since the water level 80 of the support pool 71 is relatively low, the filter assembly 20 can be positioned at a suitable location along the slide bar 104 using the adjustment function of this application, ensuring that the first end of the inlet pipe 2041 of the float 204 (i.e., the top surface of the float 204) is basically flush with the water level 80. And... Figure 17In the scenario, since the water surface 80 of the support pool 71 is relatively high, the filter assembly 20 can be adjusted upward along the slide bar 104 to a suitable position through the adjustment function of this application, and ensure that the first end of the water inlet pipe 2041 of the float 204 is basically flush with the water surface 80.

[0061] like Figure 18 and Figure 19 As shown, the skimmer 62 of this application is applied to an inflatable swimming pool 72. In this application scenario, the skimmer 62 is equipped with a second fixing component and is fixed to the upper edge of the inflatable swimming pool 72 by the second fixing component. Figure 18 In this scenario, since the water level 80 of the inflatable pool 72 is relatively low, the filter assembly 20 can be positioned at a suitable location along the slide bar 104 using the adjustment function of this application, ensuring that the first end of the inlet pipe 2041 of the float 204 (i.e., the top surface of the float 204) is basically flush with the water level 80. And... Figure 19 In the scenario, since the water surface 80 of the inflatable pool 72 is relatively high, the filter assembly 20 can be adjusted upward along the slide bar 104 to a suitable position through the adjustment function of this application, and the first end of the water inlet pipe 2041 of the float 204 is basically flush with the water surface 80.

Various modifications and variations can be made to this application by those skilled in the art.
