Abstract
Description
Technical Field
[0001] The present invention relates to a gasket and a water outlet device having the gasket. Background Art
[0002] In existing water outlet devices, such as shower heads or faucets, generally there are various water outlet sprays for users to select and use. Therefore, a water path switching structure is provided on the water outlet device, and the water path switching structure is mainly implemented by a water distribution structure. Specifically, the water distribution structure generally includes a first water distribution member and a second water distribution member that can move relative to each other. The first water distribution member is provided with a water inlet hole, the second water distribution member is provided with a plurality of water distribution holes, a counterbore is provided at the position of the water inlet hole on the first water distribution member, and a gasket is provided in the counterbore. The gasket is used to seal and block the water distribution holes that do not correspond to the current position and the water inlet hole, and allow the water flow from the water inlet hole to flow to the water distribution holes corresponding to the current position and the water inlet hole, thereby realizing the water distribution function.
[0003] Specifically, as Figure 1 shown, the existing gasket usually has a sealing bottom plate 10', and a flow-through hole 11' and a sealing portion 12' are formed on the sealing bottom plate 10'. The flow-through hole 11' is used to connect the water inlet hole and the water distribution hole so that the water flow from the water inlet hole flows to the water distribution hole through the flow-through hole 11', and the sealing portion 12' is used to seal the water distribution hole. The outer edge of the sealing bottom plate 10' extends circumferentially with a sealing skirt 20', and the sealing skirt 20' is in sealing cooperation with the inner wall of the counterbore of the first water distribution member. In the existing gasket structure, the sealing skirt 20' and the sealing bottom plate 10' enclose a cavity, and the water entering the cavity from the water inlet hole will flow to the sealing portion 12' on the sealing bottom plate 10', so that the sealing portion 12' is subjected to water pressure (such as Figure 1 the water pressure direction indicated by the arrow in), the water pressure area received by the sealing bottom plate 10' is relatively large, resulting in a relatively large pressing force of the sealing bottom plate 10' on the second water distribution member, and further resulting in a relatively large switching force for switching the first water distribution member and the second water distribution member, with poor user experience, and it is easy to cause the gasket to wear quickly and the product service life to be short. In addition, for the existing gasket, in order to keep the gasket unchanged during use, a gasket 30' made of a hard material is usually configured. The gasket 30' is supported on the non-sealing surface side of the sealing bottom plate 10'. Since the gasket 30' needs to be provided, the structure is relatively complex and the cost is relatively large. Summary of the Invention
[0004] In order to solve the above problems, the present invention provides a gasket and a water outlet device having the gasket, which can reduce the friction force at the gasket, thereby reducing the switching force when the water outlet device switches the water path, with better user experience, and since the friction force is reduced, the wear speed of the gasket can be reduced to extend the product service life.
[0005] To achieve the above object, according to one aspect of the present invention, the present invention provides the following technical solutions:
[0006] A gasket for installation at the water distribution structure of a water outlet device, comprising a sealing bottom plate. The sealing bottom plate is provided with a first flow-through hole for cooperating with the water inlet hole and the water distribution holes of the water distribution structure, and is provided with at least one sealing portion for cooperating with the water distribution holes of the water distribution structure. At a position corresponding to the sealing portion on the first side of the sealing bottom plate, there is a ring-shaped second sealing skirt. The second sealing skirt is used for sealing cooperation with the corresponding inner cavity wall of the water distribution structure to prevent the water flow in the water inlet hole from flowing along the first side of the sealing bottom plate to the sealing portion.
[0007] As a further improvement of the above solution, a ring-shaped first sealing skirt extends along the circumferential direction of the first flow-through hole on the first side of the sealing bottom plate. The first sealing skirt is used for sealing cooperation with the corresponding inner cavity wall of the water distribution structure so that the water flow in the water inlet hole flows to the first flow-through hole via the first sealing skirt.
[0008] As a further improvement of the above solution, a first stepped surface is formed on the outer periphery of the first flow-through hole, and the first sealing skirt surrounds the outer edge of the first stepped surface.
[0009] As a further improvement of the above solution, the sealing portion is provided with a second flow-through hole penetrating through both sides of the sealing bottom plate, and the second flow-through hole is used for cooperating with the water distribution hole.
[0010] As a further improvement of the above solution, a second stepped surface is formed on the outer periphery of the second flow-through hole, and the second sealing skirt surrounds the outer edge of the second stepped surface.
[0011] According to another aspect of the present invention, the present invention further provides a water outlet device, comprising a water distribution structure. The water distribution structure includes a first water distribution member and a second water distribution member that can move relative to each other. The first water distribution member is provided with a water inlet hole, and the second water distribution member is provided with a plurality of water distribution holes. A counterbore is provided at the position of the water inlet hole on the first water distribution member, and a gasket is provided in the counterbore, wherein:
[0012] The gasket includes a sealing bottom plate. The sealing bottom plate is provided with a first flow-through hole and at least one sealing portion. The first flow-through hole cooperates with the water inlet hole and the water distribution holes, and the sealing portion cooperates with the water distribution holes. At a position corresponding to the sealing portion on the first side of the sealing bottom plate, there is a ring-shaped second sealing skirt. A second inner cavity corresponding to the second sealing skirt is separated in the inner cavity of the counterbore. The second sealing skirt is in sealing cooperation with the cavity wall of the second inner cavity to prevent the water flow in the water inlet hole from flowing along the first side of the sealing bottom plate in the counterbore to the sealing portion.
[0013] As a further improvement of the above solution, a ring-shaped first sealing skirt extends circumferentially along the first through hole on the first side of the sealing bottom plate. A first inner cavity corresponding to the first sealing skirt is also partitioned in the inner cavity of the counterbore. The first sealing skirt is in sealing cooperation with the wall of the first inner cavity, so that the water flow in the water inlet hole flows to the first through hole via the first sealing skirt.
[0014] As a further improvement of the above solution, an elastic member is further included for applying an elastic force to the gasket to press it against the second water distribution member. A first stepped surface is formed on the outer periphery of the first through hole. The first sealing skirt surrounds the outer edge of the first stepped surface. One end of the elastic member abuts against the bottom wall of the counterbore, and the other end abuts against the first stepped surface. By providing the elastic member, a pre-tightening force is applied to the sealing bottom plate in the sealing direction, so that the sealing effect is more reliable.
[0015] As a further improvement of the above solution, a second through hole penetrating through both sides of the sealing bottom plate is provided on the sealing portion. The second through hole can be correspondingly matched with at least one of the water distribution holes. As a further improvement of the above solution, a second stepped surface is formed on the outer periphery of the second through hole. The second sealing skirt surrounds the outer edge of the second stepped surface. The water distribution structure is further provided with a common water outlet cavity, and the common water outlet cavity can be simultaneously communicated with the water distribution holes corresponding to the first through holes and the water distribution holes corresponding to the second through holes. By providing the second stepped surface, the water pressure in the second water outlet cavity can act on the second stepped surface, and the structure is simple.
[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0017] 1. By providing the second sealing skirt on the gasket of the present invention, and the second sealing skirt is in sealing cooperation with the wall of the second inner cavity to prevent the water flow in the water inlet hole from flowing along the first side of the sealing bottom plate to the sealing portion in the counterbore. Therefore, the position of the sealing bottom plate corresponding to the sealing portion can be not affected by the water pressure in the sealing direction (when the following second through hole is not provided in the sealing portion or the second through hole is blocked by the second water distribution member) or the resultant water pressure received is smaller or even zero (when the following second through hole is provided in the sealing portion and the water flow in the common water outlet cavity enters the second cavity via the water distribution hole and the second through hole). Therefore, the force exerted by the sealing bottom plate on the second water distribution member in the sealing direction is reduced, thereby reducing the friction force between the surface of the sealing bottom plate and the second water distribution member, and further reducing the switching force for rotating the second water distribution member, improving the user experience. And due to the reduction of the friction force, the wear speed of the gasket is greatly reduced, thereby improving the service life of the product.
[0018] 2. By setting the first sealing skirt, the water flow in the water inlet hole only flows to the first flow-through hole through the first inner cavity, thus preventing the water flow from reaching other positions on the sealing bottom plate and avoiding the formation of water pressure in the direction of sealing in other areas of the sealing bottom plate except those surrounded by the first sealing skirt, further reducing the water pressure acting force, and thereby reducing the friction between the sealing bottom plate and the second water distribution member. In addition, due to the provision of the first sealing skirt and the second sealing skirt, under the combined action of the first sealing skirt, the second sealing skirt and the corresponding inner cavity of the water distribution structure, the gasket is not prone to wrinkling and deformation during the switching process of the second water distribution member, resulting in sealing failure. Compared with the prior art, the hard gasket for supporting the sealing bottom plate can be omitted, the structure is simpler, and the cost is saved.
[0019] 3. By setting the second flow-through hole, the water flow in the common water outlet cavity in the body is allowed to enter the second inner cavity through the water distribution hole corresponding to the second flow-through hole and the second flow-through hole. The water in the second inner cavity can form water pressure in the direction of sealing on the sealing bottom plate, thereby partially offsetting or completely offsetting the water pressure in the common water outlet cavity on the sealing bottom plate in the direction away from the sealing, avoiding the problem that when the water pressure in the common water outlet cavity is relatively large, the water pressure pushes the sealing bottom plate open and separates from the second water distribution member, resulting in poor sealing.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0038] In the following discussion, details are given to provide a more thorough understanding of the present invention. However, those skilled in the art can understand that the present invention can be implemented without one or more of these details. In specific examples, in order to avoid confusion with the present invention, some well - known technical features in the art are not described in detail. It should be noted that the terms "upper", "lower", "front", "rear", "left", "right" and similar expressions used herein are for illustrative purposes only and not for limitation.
[0039] Ordinal numbers such as "first" and "second" cited in the present invention are merely identifiers and do not have any other meanings, such as a specific order, etc. Moreover, for example, the term "first component" does not imply the existence of a "second component" by itself, and the term "second component" does not imply the existence of a "first component" by itself.
[0040] Please refer to Figures 2 to 8 , the water outlet device of an embodiment of the present invention includes a body 10 and a water distribution structure disposed inside the body 10. The water outlet device can be a shower head, a spray gun, a faucet, etc. In this embodiment, a handheld shower head is taken as an example for illustration. The handheld shower head has at least two types of water outlet sprays, such as two or more of the water spray, the spray water, the sheet water, and the granular water. The function of the water distribution structure is to switch the water flow in the water inlet channel 11 of the body 10 to the waterways corresponding to different water sprays, so as to realize the water outlet of different water sprays.
[0041] Please refer to Figures 4 to 8 , in this embodiment, the water distribution structure includes a first water distribution member 20 and a second water distribution member 30 that can move relative to each other. Among them, the first water distribution member 20 is fixedly arranged relative to the body 10, and the second water distribution member 30 is rotatably arranged relative to the body 10. The first water distribution member 20 is provided with a water inlet hole 21, and the second water distribution member 30 is provided with a plurality of water distribution holes 31. A counterbore 22 is provided at the position of the water inlet hole 21 on the first water distribution member 20, and a sealing gasket 40 is provided in the counterbore 22. By rotating the second water distribution member 30, the water inlet hole 21 on the first water distribution member 20 is switched to correspond and cooperate with the water distribution holes 31 on the second water distribution member 30, so as to control the water flow to flow into the waterways of different water outlet sprays.
[0042] Among them, the main improvement of the present invention is that: the sealing gasket 40 includes a sealing bottom plate 41, the sealing bottom plate 41 is provided with a first water flow hole 411 and at least one sealing portion 412. The first water flow hole 411 cooperates with the water inlet hole 21 and the water distribution holes 31 so that the water flow of the water inlet hole 21 flows through the first water flow hole 411 to the water distribution hole 31 corresponding to the current position of the first water flow hole 411, and the sealing portion 412 cooperates with the water distribution holes 31; a ring-shaped second sealing skirt 44 is provided at the position corresponding to the sealing portion 412 on the first side of the sealing bottom plate 41, and a second inner cavity 222 corresponding to the second sealing skirt 44 is separated in the inner cavity of the counterbore 22, and the second sealing skirt 44 is hermetically fitted with the cavity wall of the second inner cavity 222 to prevent the water flow of the water inlet hole 21 from flowing along the first side of the sealing bottom plate 41 in the counterbore 22 to the sealing portion 412. Specifically, as Figure 5As shown, the water flow in the water inlet hole 21 flows through the first chamber 211 to the water distribution hole 31 corresponding to the first flow-through hole 411, and then enters the common water outlet chamber 60. The water flow in the water inlet hole 21 will not directly enter the second chamber 222 due to the sealing cooperation between the second chamber 222 and the second sealing skirt 44 in the space of the counterbore 22. With this setting, since the water flow in the water inlet hole 21 will not flow along the first side of the sealing bottom plate 41 to the sealing portion 412 in the counterbore 22, therefore, the position of the sealing bottom plate 41 corresponding to the sealing portion 412 is not subjected to the water pressure in the sealing direction (when the following second flow-through hole 4121 is not provided in the sealing portion 412 or the second flow-through hole 4121 is blocked by the second water distribution member 30 (such as Figure 5 the second flow-through hole 4121 on the left side of the gasket 40)), or the resultant water pressure received is small or even zero (when the following second flow-through hole 4121 is provided in the sealing portion 412 and the water flow in the common water outlet chamber 60 enters the second chamber 222 through the water distribution hole 31 and the second flow-through hole 4121, such as Figure 5 the second flow-through hole 4121 on the right side of the gasket 40)), therefore, the force exerted by the sealing bottom plate 41 on the second water distribution member 30 in the sealing direction is reduced, thereby reducing the frictional force between the surface of the sealing bottom plate 41 and the second water distribution member 30, and further reducing the switching force for rotating the second water distribution member 30, improving the user experience. And due to the reduction of the frictional force, the wear rate of the gasket 40 is greatly reduced, thereby improving the service life of the product.
[0043] In this embodiment, there are 3 water distribution holes 31, and there are 2 sealing portions 412 on the sealing bottom plate 41, which are symmetrically located on both sides of the first flow-through hole 411. Of course, the numbers of the water distribution holes 31 and the sealing portions 412 are not limited thereto and can be set as required.
[0044] Please refer to Figure 2 、 Figures 4 to 6, in this embodiment, a ring-shaped first sealing skirt 43 extends along the circumference of the first through-hole 411 on the first side of the sealing bottom plate 41. A first inner cavity 221 corresponding to the first sealing skirt 43 is also separated in the inner cavity of the counterbore 22. The first sealing skirt 43 is in sealing cooperation with the cavity wall of the first inner cavity 221, so that the water flow of the water inlet hole 21 flows to the first through-hole 411 via the first sealing skirt 43, and will not flow to other places of the counterbore 22 except the first inner cavity 211. By providing the first sealing skirt 43, the water flow of the water inlet hole 21 only flows to the first through-hole 411 through the first inner cavity 221, thereby preventing the water flow from flowing to other positions on the sealing bottom plate 41, and preventing the water flow from forming a water pressure in the direction of the seal at other areas on the sealing bottom plate 41 except the area surrounded by the first sealing skirt 43, further reducing the water pressure acting force, and thus reducing the friction force between the sealing bottom plate 41 and the second water distribution member 30. In addition, due to the provision of the first sealing skirt 43 and the second sealing skirt 44, under the cooperative action of the first sealing skirt 43 and the second sealing skirt 44 and the corresponding inner cavities of the water distribution structure, the gasket is not likely to be wrinkled and deformed during the switching process of the second water distribution member 30, resulting in sealing failure. Compared with the prior art, a hard gasket for supporting the sealing bottom plate 41 can be omitted, the structure is simpler, and the cost is saved.
[0045] Please refer to Figures 4 to 6 , in this embodiment, it further includes an elastic member 50 for applying an elastic force to the gasket 40 to press it against the second water distribution member 30. The elastic member 50 is specifically a compression spring. A first step surface 413 is formed on the outer periphery of the first through-hole 411. The first sealing skirt 43 surrounds the outer edge of the first step surface 413. One end of the elastic member 50 abuts against the bottom wall of the counterbore 22, and the other end abuts against the first step surface 413. The elastic member 50 can provide a pre-tightening force for the gasket 40 to fit the surface of the second water distribution member 30. Of course, the elastic member 50 is not necessary, and the gasket 40 can be pre-tightened on the second water distribution member 30 under its own elasticity.
[0046] Please refer to 5. In this embodiment, a second through-hole 4121 penetrating through both sides of the sealing bottom plate 41 is provided on the sealing portion 412. The second through-hole 4121 can be correspondingly matched with at least one water distribution hole 31. A second step surface 414 is formed on the outer periphery of the second through-hole 4121. The second sealing skirt 44 surrounds the outer edge of the second step surface 414. The water distribution structure further has a common water outlet cavity 60. The common water outlet cavity 60 can be simultaneously communicated with the water distribution holes 31 corresponding to the first through-holes 411 and the water distribution holes 31 corresponding to the second through-holes 4121. In this way, as Figure 5As shown by the arrow in [description], the water flow entering the common water outlet cavity 60 from the first water flow hole 411 can enter the second inner cavity 222 from the second water flow hole 4121, and the water flow in the second inner cavity 222 can form a first water pressure acting on the second water dividing member 30 in the sealing direction on the second step surface 414 (such as Figure 5 shown as F1 in [description]), and the water flow in the common water outlet cavity 60 forms a second water pressure on the sealing bottom plate 41 in the direction away from the sealing direction (such as Figure 5 shown as F2 in [description]). The first water pressure F1 can partially or completely offset the second water pressure F2, thereby achieving self - balance of the water pressure, effectively avoiding the problem that when the water pressure in the common water outlet cavity 60 is relatively large, the water pressure pushes open the sealing bottom plate 41 and separates from the second water dividing member 30, resulting in poor sealing.
