Description

Technical Field

[0001] The utility model relates to the field of sanitary products, in particular to a valve housing and a water outlet device. Background Art

[0002] When using the valve core, it needs to be installed inside a seat body with a water path before it can be used. The water path generally includes a hot water path. In order to prevent users from getting scalded and to make the appearance simple, a valve shell is generally set on the outside of the seat body, and then the valve stem of the valve core is turned by the knob on the valve shell to control the valve core. In existing valves, the limit part for limiting the rotation stroke of the knob is generally set on the valve core. The push rod on the knob needs to be inserted into the valve core to be able to push against the limit part so that the limit part can realize the function of limiting the rotation stroke of the knob. However, since the valve cores are different, the distance between them and the knob is different, and the push rod of a fixed length is difficult to extend into the valve core. Therefore, different valve shells need to be replaced for different valve cores, which is inconvenient. Utility Model Content

[0018] From the above description of the utility model, it can be seen that compared with the prior art, the utility model has the following beneficial effects:

[0019] In the first technical solution, the interior of the shell is suitable for installing the valve core and making the valve stem axis of the valve core parallel to the axis of the through hole, and the limiter is provided with a through hole, which is suitable for being fixed to the shell and making the through hole pass through the inside and outside of the shell, so the operating member can be fixed to the valve stem of the valve core located inside the shell and at least partially located outside the shell, and the operating member can control the valve core. The limiter is provided with a first limiter and a second limiter located on the wall of the through hole, the first limiter and the second limiter are arranged at intervals around the axis of the through hole and protrude toward the inside of the through hole, and the operating member is provided with a top abutting portion extending in a direction parallel to the axis of the through hole, the top abutting portion deviates from the axis of the through hole and is suitable for extending into the through hole, so when the operating member rotates, the first limiter and the second limiter can abut against the top abutting portion to limit the rotation stroke of the operating member. Compared with the prior art, since the position of the limit member in the technical solution is fixed, even if different types of valve cores are installed inside the shell, the positions of the first limit portion and the second limit portion will not change, and the abutting portion of the operating member can always abut the first limit portion and the second limit portion, so that the valve housing can be compatible with different types of valve cores and has good versatility.

[0020] In the second technical solution, the operating member is provided with a pressing portion, and the limiting member is also provided with a third limiting portion, which is also located on the hole wall of the through hole and protrudes toward the inside of the through hole, and the second limiting portion is located between the first limiting portion and the third limiting portion, and the pressing portion is suitable for being pressed to reduce the distance between the abutting portion and the axis of the through hole, so that the abutting portion of the operating member can pass over the second limiting portion during the rotation process to continue rotating until it abuts against the third limiting portion. Therefore, after the operating member rotates until the abutting portion abuts against the second limiting portion, the pressing portion needs to be pressed to enable the operating member to continue rotating, thereby achieving the effect of reminding the user.

[0021] In the third technical scheme, the operating member includes a rotating member, a pressing member, a push member and an elastic member. The rotating member is provided with a first extension portion and a second extension portion extending axially along the through hole. The first extension portion is farther away from the axis of the through hole than the second extension portion, and an accommodating space is formed between the remaining second extension portions; the first extension portion is also provided with a through hole located outside the shell, the pressing member is installed in the through hole and forms a pressing portion, the elastic member is located in the accommodating space and one end pushes against the pressing member and the other end pushes against the second extension portion, the push member forms a push portion, which is at least partially located in the accommodating space and passes through the pressing member along the axial direction of the through hole, and is suitable for being subjected to the elastic force of the elastic member to push against the first extension portion to limit the pressing member from leaving the through hole.

[0024] In the sixth technical solution, the first extending portion is also suitable for abutting against the limiting member, so that the limiting member can be restricted from separating from the shell.

[0025] In the seventh technical solution, the housing is provided with a mounting hole, and the shape of the stopper is adapted to the mounting hole. The stopper is suitable for being installed from the outside of the housing into the mounting hole and connected to the housing to prevent rotation, so that when the stopper is fixed to the housing, the through hole can penetrate inside and outside the housing, and installation from the outside of the housing is convenient for installation and replacement. The hole wall of the mounting hole is also provided with a support portion protruding inwardly, and the support portion is suitable for supporting the stopper so as to limit the movement of the stopper into the housing.

[0027] In the ninth technical solution, when the valve core is installed inside the shell, the axis of its valve stem and the axis of the through hole are located in the same straight line, so that when the operating member is fixed to the valve stem, the abutting portion thereon can abut the first limiting portion and the second limiting portion.

[0028] The tenth technical solution relates to a water outlet device, which has corresponding technical effects due to the adoption of the aforementioned technical solution. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] like Figure 1-5As shown, this embodiment provides a water outlet device, which includes a seat body 2, a valve core 1 and a valve housing, the valve housing includes a shell 3, a limit member 4 and an operating member 9, the valve core 1 is fixedly connected to the seat body 2, the seat body 2 is fixedly connected to the shell 3 and is located inside the shell 3.

[0047] like Figure 2 As shown, the housing 3 includes an upper housing 27 and a lower housing 28, and the upper housing 27 and the lower housing 28 are detachably fixed so that the valve seat can be installed in the housing 3. The housing 3 is provided with a mounting hole 23 located in the upper housing 27, and the hole wall of the mounting hole 23 is provided with a support portion 24 protruding toward the inside thereof and an embedding groove 25 extending along the radial direction of the mounting hole 23. In this embodiment, the support portion 24 is substantially annular, and the embedding groove 25 is formed by a notch on the support portion 24.

[0048] like Figure 2 , 3 As shown in Figures 5 and 6, the limiting member 4 is adapted to the mounting hole 23 in shape and is generally circular. The limiting member 4 is provided with a through hole 5, which is suitable for being fixed to the housing 3 and connecting the through hole 5 to the inside and outside of the housing 3. When the valve core 1 is installed inside the housing 3, the axis of the valve stem 8 is parallel to the axis 29 of the through hole. In this embodiment, the axis of the valve stem 8 is in the same straight line as the axis 29 of the through hole. The limiting member 4 is also provided with a first limiting portion 6, a second limiting portion 7 and a third limiting portion 12 located on the hole wall of the through hole 5. The first limiting portion 6, the second limiting portion 7 and the third limiting portion 12 are arranged at intervals around the axis 29 of the through hole and protrude toward the inside of the through hole 5. The second limiting portion 7 is located between the first limiting portion 6 and the third limiting portion 12. The first limiting portion 6 and the third limiting portion 12 are closer to the axis 29 of the through hole than the second limiting portion 7. The stopper 4 is suitable for being installed from the outside of the housing 3 into the mounting hole 23 of the housing 3 and being connected to the housing 3 in a non-rotatable manner, that is, the outer wall of the stopper 4 is provided with a protrusion 26 adapted to the embedding groove 25. When the stopper 4 is installed in the mounting hole 23, the protrusion 26 is correspondingly embedded in the embedding groove 25 to achieve a non-rotatable connection, and the support portion 24 can support the outer edge of the stopper 4 to limit the stopper 4 from continuing to move into the housing 3. In other embodiments, the embedding groove 25 can also be provided on the outer wall of the stopper 4, and the protrusion 26 can be provided on the hole wall of the mounting hole 23. Those skilled in the art can also set the number of the protrusion 26 and the embedding groove 25 as needed. The stopper 4 is also provided with a stopper 21 and a guide protrusion 22. The stopper 21 is also located on the hole wall of the through hole 5 and protrudes into the through hole 5. Compared with the first stopper 6, the second stopper 7 and the third stopper 12, it is closer to the inside of the housing 3 and acts as a baffle. The guide protrusion 22 protrudes toward the outside of the housing 3 along the axial direction of the through hole 5 and is in the shape of a circular ring.

[0049] The operating member 9 is adapted to be fixed to the valve stem 8 of the valve core 1 and is at least partially located outside the housing 3. It is adapted to be operated to rotate around the axis of the valve stem 8 to control the valve core 1. The operating member 9 is also provided with a top abutting portion 10 whose extension direction is parallel to the axis 29 of the through hole. The top abutting portion 10 deviates from the axis 29 of the through hole and extends into the through hole 5. When the operating member 9 rotates, the first limiting portion 6, the second limiting portion 7 and the third limiting portion 12 are adapted to abut against the top abutting portion 10 to limit the rotation stroke of the operating member 9. Specifically, the second limiting portion 7 and the third limiting portion 12 limit the operating member 9 in the same direction, and the first limiting portion 6 limits the operating member 9 in a direction opposite to the limiting direction of the second limiting portion 7 and the third limiting portion 12. The operating member 9 is also provided with a pressing portion 11. When the operating member 9 is rotated to rotate the abutting portion 10 from the first limiting portion 6 to abut the second limiting portion 7, the pressing portion 11 is adapted to be pressed to reduce the distance between the abutting portion 10 and the axis 29 of the through hole, so that the abutting portion 10 is adapted to pass over the second limiting portion 7 to continue to rotate until it abuts the third limiting portion 12. In this embodiment, the operating member 9 includes a rotating member 13, a pressing member 14, an abutting member 15 and an elastic member 16. The rotating member 13 is adapted to be fixed to the valve stem 8 of the valve core 1 and is at least partially located outside the housing 3. It is adapted to be operated to rotate around the axis of the valve stem 8 to control the valve core 1. The rotating member 13 is also provided with a first extension portion 17 and a second extension portion 18 extending axially along the through hole 5 and toward the housing 3. It is farther away from the axis 29 of the through hole than the second extension portion 18. An accommodating space 19 is formed between the first extension portion 17 and the second extension portion 18. In this embodiment, the first extension portion 17 is located at the outer edge of the rotating member 13, and the second extension portion 18 is located in the middle of the rotating member 13 and is used to be fixedly connected to the valve stem 8. When the rotating member 13 is fixedly connected to the valve stem 8, the first extension portion 17 is suitable for abutting against the stopper 4 along the axial direction of the through hole 5 to limit the stopper 4 from being separated from the housing 3. The first extension portion 17 is also sleeved outside the guide protrusion 22, so that the guide protrusion 22 can hold the first extension portion 17 to limit the displacement of the operating member 9 in the radial direction of the through hole 5. The first extension portion 17 is also provided with a through hole 20 located outside the shell 3, the pressing piece 14 is installed in the through hole 20 and forms a pressing portion 11, the elastic member 16 is located in the accommodating space 19 and one end abuts against the pressing piece 14 and the other end abuts against the second extension portion 18, the abutting member 15 is at least partially located in the accommodating space 19 and penetrates the pressing piece 14 along the axial direction of the through hole 5, and the part thereof extending into the through hole 5 forms the abutting portion 10, the stopper 21 is suitable for abutting against the abutting member 15 along the axial direction of the through hole 5, thereby limiting the abutting member 15 from moving toward the inside of the shell 3, and the abutting member 15 is suitable for being acted upon by the elastic force of the elastic member 16 to abut against the first extension portion 17, thereby limiting the pressing member 14 from separating from the through hole 20.

[0050] The working process of the water outlet device in this embodiment is as follows:

[0051] like Figure 2 , 3As shown in Figures 5 and 6, after the valve core 1 is installed in the housing 3, the limiter 4 is installed in the mounting hole 23, and the operating member 9 is fixed to the valve stem 8, the operating member 9 can be rotated to control the valve core 1. When the abutting portion 10 is located between the first limiter 6 and the second limiter 7, the operating member 9 can be rotated at will. When the pressing portion 11 is pressed, the pressing member 14 drives the abutting portion 15 to approach the axis 29 of the through hole and compresses the elastic member 16, so that the abutting portion 10 can pass over the second limiter 7, and then the operating member 9 can continue to rotate until the abutting portion 10 abuts the third limiter 12. When the abutting portion 10 returns to between the first limiter 6 and the second limiter 7, the pressing member 14 is reset under the action of the elastic force of the elastic member 16 and also drives the abutting portion 15 to reset.

[0052] In the above process, since the abutting portion 10 always extends into the through hole 5, the abutting portion 10 can always abut the first limiting portion 6, the second limiting portion 7 and the third limiting portion 12. Figure 6-7 As shown, even after the type of the valve core 1 is changed, the position of the valve core 1 is far away from the operating member 9, the valve housing in this embodiment can also be used, so that the operating member 9 can control the valve core 1 after being fixed to the valve stem 8 of the valve core 1, and the first limiting portion 6, the second limiting portion 7 and the third limiting portion 12 can always abut against the abutting portion 10 to limit the rotational stroke of the operating member 9.

[0053] In addition, in this embodiment, Figure 8 As shown, the seat body 2 is integrally formed, and a water channel structure is formed inside. The water channel structure can be formed as required without limitation. The seat body 2 is cored on the right side, so that the water channel does not need to be opened on the left side, which reduces the number of assembly parts and assembly time, reduces material costs, and reduces the injection molding cycle. Fig. 9 As shown, the seat body 2 forming the water channel is separated from the shell 3, so when the user uses the water outlet device, heat is difficult to be transferred to the shell 3, thereby preventing the shell 3 from scalding the user.

[0054] It should be noted that the selection of the type of valve core 1 or the setting of the water path inside the valve seat can be adjusted by technical personnel in this field according to actual needs, and does not involve the innovation of this patent.

[0055] In this embodiment, the valve core 1 is installed inside the housing 3 and the axis of the valve stem 8 of the valve core 1 is parallel to the axis 29 of the through hole. The stopper 4 is provided with a through hole 5, which is suitable for being fixed to the housing 3 and the through hole 5 is through the inside and outside of the housing 3, so the operating member 9 can be fixed to the valve stem 8 of the valve core 1 located inside the housing 3 and at least partially located outside the housing 3, and the operating member 9 can be operated to control the valve core 1. The stopper 4 is provided with a first stopper 6 and a second stopper 7 located on the hole wall of the through hole 5, the first stopper 6 and the second stopper 7 are arranged at intervals around the axis 29 of the through hole and protrude toward the inside of the through hole 5, and the operating member 9 is provided with a top stopper 10 extending in a direction parallel to the axis of the through hole 5, the top stopper 10 deviates from the axis of the through hole and is suitable for extending into the through hole 5, so when the operating member 9 rotates, the first stopper 6 and the second stopper 7 can abut against the top stopper 10 to limit the rotation stroke of the operating member 9. Compared with the prior art, since the position of the limit member 4 in the technical solution is fixed, even if different types of valve cores 1 are installed inside the shell 3, the positions of the first limit portion 6 and the second limit portion 7 will not change, and the abutting portion 10 of the operating member 9 can always abut the first limit portion 6 and the second limit portion 7, so that the valve housing can be compatible with different types of valve cores 1 and has good versatility.

[0056] In this embodiment, the operating member 9 is provided with a pressing portion 11, and the limiting member 4 is further provided with a third limiting portion 12, the third limiting portion 12 is also located on the hole wall of the through hole 5 and protrudes toward the inside of the through hole 5, the second limiting portion 7 is located between the first limiting portion 6 and the third limiting portion 12, the pressing portion 11 is suitable for being pressed to reduce the distance between the abutting portion 10 and the axis 29 of the through hole, so that the abutting portion 10 of the operating member 9 can pass over the second limiting portion 7 during the rotation process to continue to rotate until it abuts the third limiting portion 12. Therefore, after the operating member 9 rotates until the abutting portion 10 abuts the second limiting portion 7, it is necessary to press the pressing portion 11 to enable the operating member 9 to continue to rotate, thereby achieving the effect of reminding the user.

[0057] In this embodiment, the operating member 9 includes a rotating member 13, a pressing member 14, a resisting member 15 and an elastic member 16. The rotating member 13 is provided with a first extension portion 17 and a second extension portion 18 extending axially along the through hole 5. The first extension portion 17 is further away from the axis 29 of the through hole than the second extension portion 18, and a receiving space 19 is formed between the other second extension portions 18; the first extension portion 17 is also provided with a through hole 20 located outside the housing 3, the pressing member 14 is installed in the through hole 20 and forms the pressing portion 11, and the elastic member 16 is located in the receiving space. The pressing member 14 is accommodated in the accommodating space 19 at one end and abuts against the pressing member 14 at the other end, and the abutting member 15 forms a abutting portion 10, which is at least partially located in the accommodating space 19 and passes through the pressing member 14 along the axial direction of the through hole 5. It is suitable for receiving the elastic force of the elastic member 16 to abut against the first extending portion 17, thereby limiting the pressing member 14 from leaving the through hole 20. Therefore, when the pressing portion 11 is pressed, the elastic member 16 can be compressed, thereby driving the abutting portion 10, thereby reducing the distance between the abutting portion 10 and the axis 29 of the through hole.

[0058] In this embodiment, the limit member 4 is also provided with a stop portion 21, which is located on the hole wall of the through hole 5 and protrudes toward the inside of the through hole 5. It is suitable for abutting the push member 15 along the axial direction of the through hole 5, thereby limiting the movement of the push member 15 toward the inside of the shell 3, and preventing the push member 15 from being separated from the connection with the pressing member 14 and falling into the shell 3.

[0059] In this embodiment, the limit member 4 is further provided with a guide protrusion 22 which protrudes axially along its through hole 5 toward the outside of the shell 3. When the rotating member 13 is fixed to the valve stem 8 of the valve core 1, the first extension portion 17 is sleeved outside the guide protrusion 22. The guide protrusion 22 is suitable for abutting against the first extension portion 17 to limit the radial displacement of the operating member 9 in the through hole 5, which is beneficial to the stable rotation of the rotating member 13.

[0060] In this embodiment, the first extending portion 17 is also suitable for abutting against the limiting member 4 , so as to limit the limiting member 4 from being separated from the housing 3 .

[0061] In this embodiment, the housing 3 is provided with a mounting hole 23, and the shape of the stopper 4 is adapted to the mounting hole 23. The stopper 4 is suitable for being installed from the outside of the housing 3 into the mounting hole 23 and being connected to the housing 3 to prevent rotation, so that the through hole 5 can penetrate inside and outside the housing 3 when the stopper 4 is fixed to the housing 3, and installation from the outside of the housing 3 is convenient for installation and replacement. The hole wall of the mounting hole 23 is also provided with a support portion 24 protruding into the inside thereof, and the support portion 24 is suitable for supporting the stopper 4 so as to limit the movement of the stopper 4 into the housing 3.

[0062] In this embodiment, the hole wall of the mounting hole 23 is provided with a protrusion 26 and / or an embedding groove 25 extending radially along the mounting hole 23, and the limiting member 4 is provided with a matching embedding groove 25 and / or a protrusion 26. When the limiting member 4 is installed in the mounting hole 23, the protrusion 26 is correspondingly embedded in the embedding groove 25 to prevent the limiting member 4 and the shell 3 from relative rotation.

[0063] In this embodiment, when the valve core 1 is installed inside the shell 3, the axis of its valve stem 8 and the axis 29 of the through hole are located in the same straight line, so that when the operating member 9 is fixed to the valve stem 8, the abutting portion 10 thereon can abut the first limit portion 6 and the second limit portion 7.
