That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features. Throughout the specification, the same reference numerals indicate the same elements.

[0038] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved more clearly, the technical solutions of the present invention are further explained below with reference to the accompanying drawings and through specific implementation methods.

[0039] Embodiment 1

[0040] like Figure 1 and Figure 2As shown, a connection structure is proposed in the present embodiment, which includes a water inlet and outlet body 1 and a ball valve 2. At least two water inlets and outlets 11 are arranged on the water inlet and outlet body 1. The connection structure can realize that a ball valve 2 is integrated on each water inlet and outlet 11, so as to close or open the water inlet and outlet 11 of the water inlet and outlet body 1 through the ball valve 2; the connection structure can save intermediate connecting parts, and utilize the structure of the ball valve 2 itself to be directly integrated into the water inlet and outlet 11 of the water inlet and outlet body 1, so that the structure of the entire connection structure is simple, compact and low in cost.

[0041] Specifically, Figures 2 to 5 As shown, the ball valve 2 includes a valve body 21 and a ball 22. The ball 22 is rotatably arranged in the valve body 21, and the ball 22 abuts against the end of the water inlet and outlet 11; the connection structure also includes a coupling member 3, and the coupling member 3 is used to connect and fix the valve body 21 to the water inlet and outlet 11, so as to directly integrate the ball valve 2 into the water inlet and outlet 11 of the water inlet and outlet body 1.

[0042] Compared with the prior art, the connection structure in this embodiment no longer regards the ball valve 2 as a standard part that cannot be disassembled and installed, that is, no additional intermediate connecting parts are used for intermediate connection between the ball valve 2 and the water inlet and outlet main body 1; the ball 22 rotatably arranged in the valve body 21 is abutted against the end of the water inlet and outlet 11 of the water inlet and outlet main body 1, and the valve body 21 is fixed to the water inlet and outlet 11 through the coupling member 3, that is, the water inlet and outlet 11 of the water inlet and outlet main body 1 is used as a part of the ball valve 2, so that the ball valve 2 is directly integrated into the water inlet and outlet 11 of the water inlet and outlet main body 1, and the ball valve 2 is directly integrated into the water inlet and outlet 11 by utilizing its own structure, without the need to use additional intermediate connecting parts to connect the ball valve 2 to the water inlet and outlet main body 1, thereby saving connecting parts and reducing costs, so that the number of parts of the entire connection structure is small, the structure is simple and the compactness is good.

[0043] Furthermore, by integrating the ball valve 2 at the water inlet and outlet 11 of the water inlet and outlet body 1, the ball valve 2 at each water inlet and outlet 11 can be closed in advance before maintenance of the water inlet and outlet body 1 and the structure connected thereto, so as to avoid the siphon effect and ensure the smooth progress of the maintenance work. Figure 1 and Figure 2 As shown, the water inlet and outlet body 1 is provided with two oppositely arranged water inlets and outlets 11 on the Z axis, and one of the water inlets and outlets 11 is connected to a ball valve 2 .

[0044] Moreover, since the above-mentioned connection method is adopted between the inlet and outlet water body 1 and the ball valve 2, the ball valve 2 can be suitable for connecting different types of inlet and outlet water bodies 1, so that the connection range of the ball valve 2 is wider, thereby making the applicability and versatility of the entire connection structure better.

[0045] Furthermore, if Figure 2 and Figure 5 As shown, the ball valve 2 also includes two sealing members 25, one sealing member 25 is located between the valve body 21 and the first end surface of the sphere 22, so as to be able to seal the gap between the valve body 21 and the first end surface of the sphere 22; the other sealing member 25 is located in the water inlet and outlet body 1 and abuts against the second end surface 221 of the sphere 22, so as to be able to seal the gap between the water inlet and outlet body 1 and the second end surface 221 of the sphere 22.

[0046] By arranging one of the sealing members 25 in the water inlet and outlet body 1, that is, using one of the sealing members 25 of the ball valve 2 as a common structure of the ball valve 2 and the water inlet and outlet body 1, the integration of the ball valve 2 on the water inlet and outlet 11 is further ensured, so that the number of parts of the entire connection structure is reduced, the structure is simpler and the compactness is better. In this embodiment, the sealing member 25 is specifically a sealing gasket.

[0047] It is worth noting that the improvement focus in this embodiment lies in the integration method of the ball valve 2 on the water inlet and outlet 11 of the water inlet and outlet body 1. The specific working principle of the ball valve 2 here refers to the existing technology.

[0048] Specifically, if Figure 2 and Figure 5 As shown, the ball valve 2 further includes a valve stem 23, one end of which passes through the valve body 21 along the X-axis and is connected to the ball 22, and the valve stem 23 can drive the ball 22 to rotate around the X-axis to make the ball valve 2 open or closed; and a handle 24 is connected to the valve stem 23. In this embodiment, the handle 24 is specifically a butterfly handle.

[0049] Specifically, Figure 5 As shown, the sphere 22 is a hollow structure, that is, a second through hole 222 is provided on the inner side of the sphere 22, and the second through hole 222 connects the valve body 21 and the water inlet and outlet body 1, so that the ball valve 2 is in an open state; when the handle 24 is rotated, the handle 24 can drive the valve stem 23 to rotate around the X-axis, so as to drive the sphere 22 to rotate around the X-axis, and rotate until the second through hole 222 no longer connects the valve body 21 and the water inlet and outlet body 1. At this time, the part of the sphere 22 without the second through hole 222 completely blocks the valve body 21 and the water inlet and outlet body 1. At this time, the valve body 21 and the water inlet and outlet body 1 are no longer connected, and the ball valve 2 is in a closed state; thereby, the valve stem 23 can be driven to rotate by the rotation of the handle 24, so as to realize the switching of the entire ball valve 2 between the open state and the closed state.

[0050] Furthermore, if Figure 1 and Figure 2As shown, the coupling member 3 includes a first rod 31 and a second rod 32, and the first rod 31 is vertically connected to the opposite ends of the second rod 32 to form a U-shaped structure. The first rod 31 is inserted into the valve body 21 and the water inlet and outlet body 1 along the X-axis to connect the valve body 21 to the water inlet and outlet body 1 through the first rod 31.

[0051] Specifically, Figure 1 and Figure 2 As shown, a card slot 12 is provided on the outer peripheral surface of one end of the water inlet and outlet main body 1 located in the valve body 21, and the card slot 12 extends along the X-axis. A first through hole 211 connected to the card slot 12 is provided in the valve body 21; when the first rod 31 is inserted into the first through hole 211 along the X-axis, the first rod 31 can be snapped into the card slot 12 to snap the first rod 31 into the card slot 12.

[0052] By providing the first through hole 211 and the clamping groove 12 that are connected to each other, on the one hand, the connection between the valve body 21 and the water inlet and outlet main body 1 can be simply and conveniently achieved; on the other hand, the clamping action between the clamping groove 12 and the first rod 31 can prevent the water inlet and outlet main body 1 and the valve body 21 from rotating relative to each other, thereby ensuring the stability of the relative position between the valve body 21 and the water inlet and outlet main body 1 during the installation and connection process, which can be beneficial to the entire installation and connection process.

[0053] It is worth mentioning that the valve body 21 and the water inlet and outlet main body 1 are limitedly connected by the coupling member 3, that is, when the first rod 31 is inserted into the first through hole 211 of the valve body 21 and the card slot 12 of the water inlet and outlet main body 1 along the X-axis, since the first rod 31 needs to be carded into the card slot 12, the first rod 31 can provide an extrusion effect on the water inlet and outlet main body 1 downward along the Z-axis, so that the sealing member 25 connected to the water inlet and outlet main body 1 can be pressed against the ball 22 downward along the Z-axis, and the ball 22 can squeeze the sealing member 25 connected to the valve body 21 downward along the Z-axis, so that when the ball valve 2 is in a closed state, the sealing effect between the sealing member 25 and the ball 22 can be guaranteed.

[0054] Furthermore, if Figures 1 to 6 As shown, a protrusion 212 is provided on the outer peripheral surface of the valve body 21, and a first through hole 211 penetrates the valve body 21 and two relatively arranged protrusions 212 along the X-axis. The slot 12 is located in the valve body 21 and between the two relatively arranged protrusions 212 on the X-axis. That is, after the first rod 31 passes through the first through hole 211 of one of the protrusions 212 along the X-axis, it passes through the slot 12, and then passes into the first through hole 211 of the other protrusion 212. At this time, the first rod 31 is snapped into the slot 12, thereby realizing the plug-in connection between the valve body 21 and the water inlet and outlet body 1 by the first rod 31.

[0055] Specifically, if Figure 1As shown, when the first rod 31 is inserted into the first through hole 211 and the slot 12, the second rod 32 is spaced outside the valve body 21 to avoid interference between the second rod 32 and the valve body 21 during the plugging process, thereby ensuring the smooth progress of the plugging process.

[0056] Furthermore, if Figure 1 , Figure 2 and Figure 5 As shown, a support platform 213 is further provided on the outer peripheral surface of the valve body 21. When the first rod 31 is plugged into and connected to the valve body 21 and the water inlet and outlet main body 1, the support platform 213 is used to support the second rod 32, that is, the second rod 32 is located on the support platform 213 at this time, so that the support platform 213 can provide support for the second rod 32, thereby ensuring that the first rod 31 is in a horizontal state on the X-axis in the valve body 21 and the water inlet and outlet main body 1, and further ensuring that the first rod 31 is plugged in horizontally along the X-axis, avoiding the first rod 31 from tilting and offsetting and affecting the plug-in connection effect of the valve body 21 and the water inlet and outlet main body 1.

[0057] Specifically, Figure 1 , Figure 2 and Figure 5 As shown, a stopper 214 is protruded upward along the Z-axis on one side of the support platform 213, so that the second rod 32 can be limited to the support platform 213 by the stopper 214, thereby providing a limiting effect for the second rod 32, which is beneficial to ensure the stability of the position of the second rod 32, thereby better ensuring the plug-in connection effect of the first rod 31 on the water inlet and outlet main body 1 and the valve body 21.

[0058] The connection structure in this embodiment uses the ball body 22 to abut the end of the water inlet and outlet 11, so that the water inlet and outlet 11 is used as a part of the ball valve 2, and a sealing member 25 of the ball valve 2 is used as a common structure of the ball valve 2 and the water inlet and outlet body 1. At the same time, the valve body 21 is connected and fixed to the water inlet and outlet 11 through the coupling member 3, so that the ball valve 2 is directly integrated into the water inlet and outlet 11, so as to save intermediate connecting parts, reduce costs, and ensure the compactness of the connection structure.

[0059] Embodiment 2

[0060] This embodiment provides a filter such as Figure 3 and Figure 4 As shown, the filter includes a filter body 4, a connector 5 and a connection structure as in the first embodiment, and the connector 5 is used to connect to the filter body 4 and the water inlet and outlet body 1 to achieve the connection between the filter body 4 and the water inlet and outlet body 1. The filter in this embodiment is specifically a magnetic filter, and the specific type of the filter is not limited here.

[0061] Specifically, Figure 3As shown, the connecting member 5 includes an annular plug-in rod, which is plugged into the filter body 4 and the water inlet and outlet body 1 to achieve a plug-in connection between the filter body 4 and the water inlet and outlet body 1, and after the plug-in connection, the filter body 4 and the water inlet and outlet body 1 can rotate relative to each other around the Y axis.

[0062] Furthermore, if Figure 1 and Figure 6 As shown, a plurality of limit blocks 13 are provided on one of the water inlet and outlet body 1 and the filter body 4, and a plurality of clamping blocks are provided on the other one, and a clamping block can be clamped between two adjacent limit blocks 13 to realize the positioning between the water inlet and outlet body 1 and the filter body 4, so as to facilitate the annular plug-in rod to be plugged into the filter body 4 and the water inlet and outlet body 1, and ensure that the plug-in between the filter body 4 and the water inlet and outlet body 1 is more accurate. In this embodiment, the limit blocks 13 are provided on the water inlet and outlet body 1, and the clamping blocks are provided on the filter body 4. In other embodiments, the clamping blocks can also be provided on the water inlet and outlet body 1, and the limit blocks 13 can be provided on the filter body 4, which is not specifically limited here.

[0063] Specifically, due to different types of filter bodies 4 or water inlet and outlet bodies 1, the flow channel structures respectively arranged in the filter bodies 4 or water inlet and outlet bodies 1 are also different. Therefore, before the filter body 4 is plugged and connected with the water inlet and outlet body 1, it is necessary to rotate the filter body 4 or the water inlet and outlet body 1 according to the actual flow channel structure in the filter body 4 or the water inlet and outlet body 1, so that the flow channel structure in the filter body 4 is adapted to the flow channel structure in the water inlet and outlet body 1, and at this time, the card block on the filter body 4 can be connected between the corresponding two adjacent card blocks on the water inlet and outlet body 1, so that the flow channel structure in the filter body 4 can be adapted to the flow channel structure in the water inlet and outlet body 1, so that the applicability and versatility of the entire filter are better.

[0064] In this embodiment, four clamping blocks are arranged around the filter body 4, and a plurality of limiting blocks 13 are arranged around the water inlet and outlet body 1, so that the relative rotation angle between the water inlet and outlet body 1 and the filter body 4 can be better adapted by a large number of limiting blocks 13, thereby ensuring a 360° selectable angle installation between the water inlet and outlet body 1 and the filter body 4. Here, the number of clamping blocks and limiting blocks 13 is not specifically limited.

[0065] When installing the filter body 4 and the water inlet and outlet body 1: first, according to the actual flow channel structure in the filter body 4 and the actual flow channel structure in the water inlet and outlet body 1, rotate the water inlet and outlet body 1 or the filter body 4 to a suitable angle; then, at this angle, make a block on the filter body 4 snap into place between two corresponding adjacent limit blocks 13 on the water inlet and outlet body 1 to achieve positioning between the filter body 4 and the water inlet and outlet body 1; then, plug the annular plug-in rod into the filter body 4 and the water inlet and outlet body 1, so as to connect the filter body 4 to the water inlet and outlet body 1.

[0066] The filter in this embodiment, by providing a limit block 13 and a clamping block that cooperate with each other, can, after the water inlet and outlet body 1 or the filter body 4 is rotated to an appropriate angle, the clamping block can be clamped between two corresponding adjacent limit blocks 13 to achieve 360° rotational positioning between the water inlet and outlet body 1 and the filter body 4, so that the filter body 4 can be adapted to water inlet and outlet bodies 1 with a variety of different flow channel structures, and there is no need to additionally provide a conversion joint between the filter body 4 and the water inlet and outlet body 1 for conversion connection, thereby reducing the use of parts, reducing costs, and ensuring the compactness of the structure of the entire filter.

[0067] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
