Description

Technical Field

[0001] This utility model relates to the field of aquarium supplies technology, and in particular to a water intake device, a filter and an aquarium. Background Technology

[0002] An aquarium is a glass container used to keep tropical fish or goldfish for ornamental purposes. It is a container specifically designed for keeping aquatic plants and animals, serving as an animal enclosure, and typically has at least one side made of transparent glass and high-strength plastic.

[0003] Currently, a common practice is to suspend a filter on one of the outer walls of the aquarium, using inlet and outlet pipes to circulate water within the aquarium. Externally mounted filters reduce space requirements and are therefore popular. However, because the filter is externally mounted, air can accumulate inside the filter housing after initial use or cleaning, causing the pump to run dry during startup and preventing proper water flow and circulation. Utility Model Content

[0004] The purpose of this utility model is to provide a water intake device, filter and aquarium, which has a simple structure and the application of its water intake component can actively fill the water in the aquarium into the first receiving cavity, ensuring the water content in the first receiving cavity so that the water pump can be started later.

The water-drawing pipe has an inlet and an outlet arranged vertically, with the outlet located above the inlet. The one-way valve is slidably disposed within the water-drawing pipe. Along the length of the water-drawing pipe, the one-way valve divides the water-drawing pipe into a second receiving cavity and a third receiving cavity. The second receiving cavity is connected to the first receiving cavity via the outlet. The first receiving chamber is connected to the pump room, and the water inlet is connected to the third receiving chamber. The driving member is connected to the one-way valve so as to drive the one-way valve to reciprocate between the first position and the second position. When the one-way valve moves from the first position to the second position, the water in the third receiving chamber can flow into the second receiving chamber through the one-way valve. When the one-way valve moves from the second position to the first position, the one-way valve can push the water in the second receiving chamber into the first receiving chamber and generate negative pressure in the third receiving chamber to draw in external water through the water inlet.

The structure and operation are simple, and it can effectively reduce the phenomenon of air in the first receiving cavity causing the subsequent pump to run dry or other ineffective operation.

Detailed Implementation

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" 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 or an electrical 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 utility model based on the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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 utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0036] Because the filter is externally mounted, the first cavity inside the filter housing is empty with zero water content during initial use. At this time, the pump chamber (such as a centrifugal water pump) inside the first cavity is also empty. The pump will run dry when started, unable to generate suction to pump water through the inlet pipe, making manual water filling inconvenient. Alternatively, if the pump stops due to power outages or cleaning, the inlet and outlet pipes located on the edge of the tank may contain air because they are above the water surface in the tank. If the pump is located at the top of the first cavity, it will be unable to operate when restarted due to the air in the pump chamber. Or, due to the siphon effect of the inlet pipe, water in the first cavity may be drawn back into the tank, causing a lack of water in the first cavity. All of these situations will cause the pump to run dry when started, preventing water flow and circulation.

[0037] To solve the above problems, such as Figures 1 to 5 As shown, the water-drawing device of this utility model embodiment includes a housing 1 and a water-drawing assembly 2. The housing 1 has a first receiving cavity 11, and a water pump 100 is installed in the first receiving cavity 11. The water pump 100 is provided with a pump room, which is connected to the first receiving cavity 11. The water-drawing assembly 2 includes a water-drawing pipe 21, a driving component 22, and a one-way valve 23. The water-drawing pipe 21 has an inlet and an outlet arranged vertically, with the outlet located above the inlet. The one-way valve 23 is slidably installed in the water-drawing pipe 21. Along the length of the water-drawing pipe 21, the one-way valve 23 divides the water-drawing pipe 21 into a second receiving cavity 211 and a third receiving cavity 212. The second receiving cavity 211 is connected to the first receiving cavity 11 or the pump room through the outlet. When the outlet location is limited, the inlet can be connected to the first receiving cavity through a connecting pipe. The pump room is connected to the inlet of the pump, and the inlet is connected to the third receiving chamber 212. The drive unit 22 is connected to the one-way valve 23 so as to drive the one-way valve 23 to move back and forth between the first position and the second position. When the one-way valve 23 moves from the first position to the second position, the water in the third receiving chamber 212 can flow into the second receiving chamber 211 through the one-way valve 23. When the one-way valve 23 moves from the second position to the first position, the one-way valve 23 can push the water in the second receiving chamber 211 into the first receiving chamber 11 and generate negative pressure in the third receiving chamber 212 to draw in external water through the inlet. The one-way valve 23 moves back and forth between the first position and the second position to realize repeated pumping to fill the first receiving chamber 11 with water or fill the first receiving chamber 11 with water so that the pump can operate.

[0038] It is understandable that by setting up the water intake component 2, the drive component 22 drives the one-way valve 23 to move back and forth, drawing water from the water tank through the water intake pipe 21 into the first receiving cavity 11, so as to ensure the water filling effect of the first receiving cavity 11, thereby ensuring the water filling effect of the pump room 11 of the water pump 100, so that the water pump 100 can drive the water flow normally. The structure and operation are simple, and it can effectively reduce the phenomenon of ineffective operation such as dry running of the subsequent water pump 100 caused by air in the first receiving cavity 11.

[0039] It should be noted that, initially, there may be some air in the third accommodating cavity 212. Therefore, when the driving member 22 moves the one-way valve 23 in the early stage, the one-way valve 23 pushes the air in the third accommodating cavity 212 to be input into the first accommodating cavity 11 through the second accommodating cavity 211. Subsequently, the driving member 22 drives the one-way valve 23 to move back and forth so that the water introduced through the water pipe 21 can displace this part of the air, thus preventing the gas in the third accommodating cavity 212 from entering the first accommodating cavity 11 and affecting the operation of the water pump 100.

[0040] Furthermore, such as Figure 2 and Figure 3 As shown, the one-way valve 23 includes a valve body 231 and a valve 232. The valve body 231 is slidably disposed in the water inlet pipe 21. The valve body 231 has a first mounting hole 2311 through it along a first direction (the first direction is the X direction shown in the figure, which can be a vertical direction or a direction set at an acute angle to the vertical direction). The wall of the first mounting hole 2311 has a stop portion 2312 that protrudes annularly around the central axis of the first mounting hole 2311. The stop portion 2312 surrounds and forms a connecting port 2313, which connects the second receiving cavity 211 and the third receiving cavity 212. The valve 232 is rotatably connected to the wall of the first mounting hole 2311 and is located above the stop portion 2312. The valve 232 can abut against the stop portion 2312 to block the connecting port 2313. The rotation of valve 232 cooperates with the stop part 2312 on valve body 231 to effectively seal the connection port 2313. When valve 232 abuts against the stop part 2312, the connection port 2313 is blocked, and the flow and stop of water between the two cavities are precisely controlled, effectively ensuring the water intake needs of the first cavity 11.

[0041] In other words, the driving element 22 moves the valve body 231 from the first position to the second position, causing the volume of the second receiving cavity 211 to gradually increase and the pressure to decrease, while the volume of the third receiving cavity 212 gradually decreases. The gas or liquid in the third receiving cavity 212 can push the valve 232 open, allowing water in the third receiving cavity 212 to flow into the second receiving cavity 211 through the connecting port 2313. The driving element 22 moves the valve body 231 from the second position to the first position, causing the water in the second receiving cavity 211 to press the valve 232 to close the connecting port 2313, ensuring that the water in the second receiving cavity 211 can only flow towards the first receiving cavity 11 with the pulling of the valve body 231. This one-way valve 23 has a simple structure and is convenient to manufacture and assemble. Of course, the one-way valve 23 can also adopt other common fluid flow structures that allow only unidirectional flow, but these will not be elaborated upon here.

[0042] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, the water inlet pipe 21 includes a first pipe section 213 and a second pipe section 214. The first pipe section 213 is connected to the second pipe section 214. The end of the second pipe section 214 away from the first pipe section 213 is provided with a water outlet connected to the housing 1. The second pipe section 214 extends along a second direction (the second direction is the Y direction shown in the figure). The first pipe section 213 extends along a first direction. The end of the first pipe section 213 away from the second pipe section 214 is provided with a water inlet. The valve body 231 is slidably connected inside the first pipe section 213. The driving component 22 includes a driving rod. The second pipe section 214 has a second mounting hole. The driving rod is slidably connected to the second mounting hole. One end of the driving rod is connected to the valve body 231. The end of the driving rod away from the valve body 231 extends through the second mounting hole to the outside of the water inlet pipe 21. The first direction and the second direction are perpendicular. The operator pulls the end of the drive rod away from the valve body 231 and moves it repeatedly in the first direction, thereby dragging the valve body 231 to move back and forth in the first and second positions, so that the water in the water tank can flow to the first receiving cavity 11 through the first pipe section 213 and the second pipe section 214. The structure is simple and the operation is convenient.

[0043] In addition, the drive component 22 may also include linear drives such as cylinders, hydraulic cylinders, or electric cylinders. Taking a cylinder as an example, the end of the drive rod away from the valve body 231 is connected to the drive end of the cylinder. When the cylinder is activated, it can reciprocate to drive the valve body 231 to move back and forth between the first position and the second position along the first direction. Of course, the drive component 22 may also use a motor in conjunction with a worm gear or rack and pinion to drive the drive rod to move, but we will not go into too much detail here. When the operator manually pulls the drive rod, a handle can be provided at the end of the drive rod away from the valve body 231 to facilitate manual operation and improve the ease of operation of the drive rod.

[0044] Alternatively, in addition to the above-mentioned first pipe section 213 being connected to the bottom side of the second pipe section 214, the water inlet pipe 21 can also have the first pipe section 213 extending along the first direction and the second pipe section 214 being connected to the periphery of the first pipe section 213. In this case, the first pipe section 213 has a second mounting hole at the end away from the water inlet along the first direction, the drive rod is slidably connected to the second mounting hole, one end of the drive rod is connected to the valve body 231, and the end of the drive rod away from the valve body 231 extends through the second mounting hole to the outside of the water inlet pipe 21. The first direction is perpendicular to the second direction.

[0045] Preferably, the drive rod is rotatably connected to the valve body 231, which increases the degree of freedom at the connection between the drive rod and the valve body 231, avoids the restriction of the drive rod by the wall of the second mounting hole, and prevents the drive rod from getting stuck due to the fixed connection between the drive rod and the valve body 231, thus improving the smoothness of the drive rod driving the valve body 231. In this embodiment, the drive rod is provided with a rotating shaft, which is rotatably connected to the wall of the first mounting hole 2311, thereby realizing the rotatable connection between the drive rod and the valve body 231.

[0046] Furthermore, such as Figure 2 and Figure 4 As shown, the water intake assembly 2 also includes a first sealing ring 24, which is sleeved on the drive rod and used to seal the gap between the drive rod and the wall of the second mounting hole. The first sealing ring 24 enhances the sealing performance of the second receiving cavity 211, ensuring that the pressure and water flow within the second receiving cavity 211 remain at a normal level and flow to the first receiving cavity 11. This prevents water or air leakage from the second receiving cavity 211, thereby reducing water loss due to leakage, improving water circulation efficiency, and avoiding unnecessary water waste.

[0047] Of course, such as Figure 2 and Figure 3 As shown, the water intake assembly 2 also includes a second sealing ring 25, which is sleeved on the outside of the valve body 231. The second sealing ring 25 is used to seal the gap between the valve body 231 and the inner wall of the first pipe section 213. The second sealing ring 25 ensures that the pressure and water flow in the second receiving cavity 211 can be maintained at a normal level and flow to the first receiving cavity 11, preventing water in the second receiving cavity 211 from flowing back to the water tank through the gap between the valve body 231 and the first pipe section 213. This ensures the water flow traction efficiency of the water intake assembly 2 and results in high pumping efficiency.

[0048] Optionally, when the water intake assembly 2 includes a first sealing ring 24 and the second pipe section 214 has a second mounting hole, a surrounding wall 215 protrudes from the outer wall of the second pipe section 214 around the central axis of the second mounting hole. The surrounding wall 215 forms a first limiting groove 216. The first sealing ring 24 is engaged between the drive rod and the groove wall of the first limiting groove 216. The one-way valve 23 also includes a limiting member 217, which is detachably connected to the surrounding wall 215. The limiting member 217 is used to prevent the first sealing ring 24 from falling out of the first limiting groove 216. By placing the first sealing ring 24 between the surrounding wall 215 and the drive rod, and using the limiting member 217 to restrict it, the first sealing ring 24 can effectively seal the gap between the drive rod and the hole wall of the second mounting hole, preventing the first sealing ring 24 from moving or falling off. Furthermore, the detachable connection of the limiting member 217 facilitates the replacement of the first sealing ring 24. For example, the detachable method can be a threaded connection, that is, the outer peripheral wall of the enclosure 215 is provided with a first thread, and the limiting member 217 is sleeved outside the enclosure 215, that is, the inner side wall of the limiting member 217 is provided with a second thread, and the first thread and the second thread cooperate.

[0049] Optionally, when the water intake assembly 2 includes a first sealing ring 24 and the first pipe section 213 has a second mounting hole, the outer wall of the first pipe section 213 protrudes around the central axis of the second mounting hole and is provided with a surrounding wall 215. The surrounding wall 215 encloses and forms a first limiting groove 216. The first sealing ring 24 is engaged between the drive rod and the groove wall of the first limiting groove 216. The one-way valve 23 also includes a limiting member 217. The limiting member 217 is detachably connected to the surrounding wall 215. The limiting member 217 is used to prevent the first sealing ring 24 from coming out of the first limiting groove 216.

[0050] Furthermore, when the water intake assembly 2 includes the second sealing ring 25, a second limiting groove 2314 is recessed on the outer peripheral wall of the valve body 231, and the second sealing ring 25 is engaged within the second limiting groove 2314. The provision of the second limiting groove 2314 effectively improves the installation stability of the second sealing ring 25 on the valve body 231, reducing the likelihood of the second sealing ring 25 detaching from the outer peripheral wall of the valve body 231.

[0051] An embodiment of this utility model also provides a filter, such as... Figures 1 to 6As shown, the device includes a filter element, an inlet pipe 200, an outlet pipe 300, and a water-guiding device as described above. Both the inlet pipe 200 and the outlet pipe 300 are connected to the housing 1 of the water-guiding device. One end of the inlet pipe 200 extends into the first receiving cavity 11 of the housing 1 and is adjacent to the bottom of the first receiving cavity 11. One end of the outlet pipe 300 extends into the pump chamber of the water pump 100 in the first receiving cavity 11. At this time, the water pump 100 is located at the top of the first receiving cavity 11. The water pump 100 can return the water in the pump chamber to the water tank through the outlet pipe 300. The water-guiding pipe 21 of the water-guiding component 2 of the water-guiding device is connected to the first receiving cavity 11 or the pump chamber. A filter element is provided in the first receiving cavity 11.

[0052] Understandably, by setting up the water intake device, the driving component 22 of the water intake assembly 2 can drive the one-way valve 23 to move back and forth, drawing water from the water tank through the water intake pipe 21 into the first receiving cavity 11, so as to ensure the water filling effect of the first receiving cavity 11. The structure and operation are simple, which can effectively reduce the phenomenon of air in the first receiving cavity 11 causing the subsequent water pump 100 to run dry and other ineffective operations, so that the water pump 100 can be driven normally to realize the water circulation between the water tank, the inlet pipe 200, the first receiving cavity 11 and the outlet pipe 300.

[0053] The specific operating procedure, taking the case where air in the first receiving cavity 11 causes the water pump 100 to fail to drive normally during initial use as an example, is as follows: When the water pump 100 is started, the pump chamber of the water pump 100 is dry due to lack of water. The operator pulls the end of the drive rod away from the valve body 231 and moves it back and forth in the first direction to allow the water in the water tank to flow through the third receiving cavity 212 and the second receiving cavity 211 to the first receiving cavity 11, filling the first receiving cavity 11 and expelling the air in the first receiving cavity 11 through the water outlet pipe 300, until the pump chamber of the water pump 100 is full of water. The water pump 100 can then drive normally to realize the water flow through the water outlet pipe 300, completing the water intake operation in the first receiving cavity 11. The water pump 100 can then drive normally to realize water circulation.

[0054] It should be noted that when the water pump 100 is installed on the top side of the first receiving cavity 11, the water priming device can solve the problem that when the water pump 100 needs to be restarted after the filter is shut down due to power failure or other reasons, there is water in the first receiving cavity 11, but there is air at the top of the first receiving cavity, which prevents the water pump 100 from starting. That is, the driving component 22 of the water priming assembly 2 can drive the one-way valve 23 to move back and forth, so that the water in the water tank is drawn into the first receiving cavity 11 by the water priming pipe 21 until the water pump 100 starts and water flows out of the outlet pipe 300.

[0055] In addition, such as Figure 6As shown, in addition to being connected to the outlet pipe 300, the pump house of the water pump 100 can also have one end of the inlet pipe 200 extending into the pump house of the water pump 100 in the housing 1. The pump house is connected to the first receiving cavity 11. One end of the outlet pipe 300 extends into the first receiving cavity 11 of the housing 1 and is adjacent to the top side of the first receiving cavity 11, i.e., the water intake assembly 2. The water pump 100 can pump water from the water tank to the first receiving cavity 11 through the inlet pipe 200. A filter element is provided in the first receiving cavity 11. The water pump 100 can be located on the bottom or top side of the first receiving cavity 11, but the positions of the inlet pipe 200 of the outlet pipe 300 and the water pump 100 should be adjacent to the two sides of the first receiving cavity 11 in the vertical direction, so that the water flowing into the first receiving cavity 11 can pass through the filter element over a longer distance.

[0056] Of course, in some embodiments, the water inlet device is not limited to being applied to the filter; it can also be used to perform simple drainage or water replacement operations within the water tank.

[0057] Furthermore, the water inlet pipe 21 of the water inlet assembly 2 of the water inlet device is the water inlet pipe 200. Integrating the water inlet pipe 21 and the water inlet pipe 200 into a single pipe reduces the number of parts, saves space, and reduces costs. Simultaneously, during pump operation, the suction within the first receiving chamber 11 causes water to flow through the water inlet pipe 200, pulling the valve 232 open. The one-way valve 23 does not affect the normal circulation and filtration of the water inlet pipe 200.

[0058] In addition, when the water inlet pipe 21 and the water outlet pipe 200 are two separate pipes, a switch valve should be installed on the water inlet pipe 21. The switch valve should be closed when the water pump 100 starts to ensure the stability of the water circulation between the water outlet pipe 200, the first receiving chamber 11, the water outlet pipe 300 and the water tank.

[0059] Furthermore, the filter also includes a wall mount 400, which is mounted on the housing 1, allowing the housing 1 to be hung on the edge of the water tank via the wall mount 400. The wall mount 400 facilitates installation by allowing the housing 1 to be hung on the edge of the water tank.

[0060] An embodiment of this utility model also provides an aquarium, including a water tank and a filter of any of the above embodiments. The water tank is filled with water, and the filter is hung outside the water tank. The end of the filter's inlet pipe 200 away from the housing 1 is inserted into the water tank and located below the water surface, and the end of the filter's outlet pipe 300 away from the housing 1 is inserted into the water tank and located above the water surface.

[0061] Understandably, the filter of this aquarium, through the setting of the water intake device, enables the drive component 22 of the water intake assembly 2 to drive the one-way valve 23 to move back and forth, drawing water from the water tank through the water intake pipe 21 into the first receiving cavity 11, so as to ensure the water filling effect of the first receiving cavity 11. The structure and operation are simple, which can effectively reduce the phenomenon of air in the first receiving cavity 11 causing the subsequent water pump 100 to run dry and other ineffective operations, so that the water pump 100 can be driven normally to realize the water circulation between the water tank, the inlet pipe 200, the first receiving cavity 11 and the outlet pipe 300.

[0062] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
