Description

Technical Field

[0001] The utility model relates to the field of water filters, in particular to an external filter structure of a swimming pool and a swimming pool. Background Art

[0002] The water purifier can filter out harmful substances in the pool water and purify the water quality in the swimming pool. This filtration work is completed by the "filter element", the spleen of the water purifier. The filter element has a service life. Once the filter element expires, the water purifier will not only fail to complete the water purification function, but also release harmful substances. In some public places, due to the large number of users, the water purifier is often used, and the filter element is worn out quickly. Relatively speaking, the life of the filter element will be shortened. In addition, the water quality in some areas may be different. If you continue to soak in the swimming pool when the water quality does not meet the standard, it will cause certain harm to the human body. The continuous maintenance of the water quality standard can only be achieved by continuous and timely replacement of the filter element. In the current traditional water purification and filtration devices, replacing the filter element basically requires disconnecting the water supply circuit before replacing it. The operation is cumbersome and the workload is large, and the disadvantages are obvious. Utility Model Content

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0023] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0024] In the description of the present utility model, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "installed / connected", "connected", etc. should be understood in a broad sense. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be a direct connection or an indirect connection through an intermediate medium. It can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.

[0025] refer to Figure 1-6The external filter structure of a swimming pool described in this embodiment includes a filter part 2 and a connecting part 1. The connecting part 1 forms a detachable connection relationship with the filter part 2. The connecting part has a water inlet 103 and a water outlet 104 arranged outside the swimming pool; thus, an external installation of the filter part 2 is formed.

[0026] When the connection part 1 is connected to the filter part 2, the water inlet 103 and the water outlet 104 are connected through the filter part 2; when the connection part 1 is disconnected from the filter part 2, the water inlet 103 and the water outlet 104 are disconnected. Therefore, as long as the connection part 1 is disconnected from the filter part 2, no water will flow out of the water outlet 104, and the user can replace the filter part 2 outside the swimming pool without worrying about water leakage.

[0027] In order to realize the above-mentioned mechanical connection, the connecting part 1 is mechanically connected to the filtering part 2, and the connecting part 1 is provided with a first chamber 101 connected to the raw water inlet 201 of the filtering part 2 and a second chamber 102 for filtering water outlet 202, and each of the chambers is provided with a one-way valve 1-1. In the unplugged state, the one-way valve 1-1 is closed, and the raw water path is disconnected; in the plugged state, the one-way valve 1-1 is opened, and the raw water flows along the first chamber 101 to the filtering part 2 for filtration and is discharged to the water outlet 104 through the second chamber 102.

[0028] Specifically, a slide groove 1-3 is provided in the chamber accommodating the one-way valve 1-1 on the connecting part 1. In the plugged state, the one-way valve 1-1 is subjected to the pushing force to compress the spring 1-2 into the chamber along the direction of the slide groove 1-3. The spring 1-2 is deformed under the action of the squeezing force. At this time, the passage from the first chamber 101 to the entrance of the filter part 2 is opened, and the raw water flows along the first chamber 101 to the filter part 2 for filtration.

[0029] Correspondingly, since the one-way valve 1-1 on the first chamber 101 and the one-way valve 1-1 on the second chamber 102 are located at the same spatial position, when the first chamber 101 is pushed open, the second chamber 102 is also opened at the same time, and the raw water flows along the first chamber 101 to the filter part 2 for filtration and then is discharged to the water outlet 104 of the connecting part 1 along the reflux channel, completing the filtration of the water body.

[0030] From a detailed perspective, a boss 2-1 is provided at the position of the raw water inlet 201 and the filtered water outlet 202 of the filter part 2 relative to the one-way valve 1-1 of the connecting part 1. When in the plugged-in state, the boss 2-1 presses against the one-way valve 1-1 to cause axial displacement of the one-way valve 1-1 and thus open the chamber, thereby breaking through the barrier between the connecting part 1 and the filter part 2 and completing the docking of the flow channels of the two functional components.

[0031] Since the connection part 1 and the filter part 2 are mechanically connected, the connection method is plug connection. Considering the stability of the connection between the two parts and the need for users to frequently disassemble, assemble and replace the two parts, the utility model is provided with a plug connector 105 at the bottom of the connection part 1, and a plug socket 203 adapted to the plug connector 105 is provided at the relative position of the filter part 2. Since the water body has a certain water pressure when supplying flow, considering the stability of the interface bite sleeve of the filter part 2 and the connection part 1, the utility model is provided with a hook 204 above the filter part 2, and the hook 204 is engaged with the card points 1-4 at the corresponding position on the connection part 1, so as to further lock the connection part 1 and the filter part 2.

[0032] On the whole, considering that the filter element structure needs to be replaced frequently during the use of the swimming pool to ensure the water quality of the filtered water, the swimming pool filter structure described in the utility model adopts an external filter component to cooperate with the swimming pool system. The external filter element structure allows the operator to avoid the inconvenience of the water working environment when replacing the filter element, and there is no need to disconnect the water source circuit during replacement, which makes the operation more convenient and the installation and disassembly accuracy higher.

[0033] During installation, the user pushes the filter part 2 with the assembled filter element 205 into the relative slot of the plug connector 105 of the connecting part 1 along the direction of the plug socket 203 until the raw water inlet 201 and the filtered water outlet 202 of the filter part 2 are engaged with the first chamber 101 and the second chamber 102 of the connecting part 1. At this time, the chamber accommodating the one-way valve 1-1 is opened under the action of the boss 2-1, and in this process, the hook 204 forms an inclined surface with the card point 1-4 so that the hook 204 opens under the action of the force, so that the hook 204 can continue to move forward relative to the card point 1-4 until the action force between the hook 204 and the card point 1-4 disappears, the hook 204 is reset and engaged with the card point 1-4, and the filter structure is installed.

[0034] When removing and replacing, the user only needs to pull the hook 204 connected to the clamping point 1-4 of the connection part 1 to disengage it from the limit position, and remove the filter part 2 in the opposite direction of the plug connector 105 approaching the connection part 1. At this time, the force acting on the one-way valve 1-1 disappears, and the one-way valve 1-1 is closed under the action of the restoring force of the spring 1-2, and the raw water channel is disconnected. Next, the user needs to push the filter part 2 with the assembled filter element 205 into the relative groove of the plug connector 105 of the connecting part 1 along the direction of the plug socket 203, and push it until the raw water inlet 201 and the filtered water outlet 202 of the filter part 2 are engaged with the first chamber 101 and the second chamber 102 of the connecting part 1. At this time, the chamber accommodating the one-way valve 1-1 is opened under the action of the boss 2-1, and in this process, the hook 204 and the card point 1-4 form an inclined surface to cooperate so that the hook 204 opens under the action of the force, so that the hook 204 can continue to move forward relative to the card point 1-4 until the action force between the hook 204 and the card point 1-4 disappears, the hook 204 is reset and engaged with the card point 1-4, and the filter structure is installed.

[0035] This embodiment also provides a swimming pool equipped with the above-mentioned external filter structure of the swimming pool.

[0036] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
