Description

Technical Field

[0001] The invention relates to a water outlet device, in particular to a water outlet device capable of outlet raw water and purified water. Background Art

[0002] Traditional raw water and water purification switching are mostly divided into two water paths, one is all purified water, and the other is all raw water. This makes the water flow through the filter element in the water purification mode. Although it can enhance the water purification effect, the water inlet area of ​​the filter element is small. When the filter element is filled with calcium sulfite with smaller particles or other things with higher density, this will reduce the amount of water passing through the filter element, and the water output from the cover will become weaker, affecting the bathing experience.

[0003] The valve core switching component of the traditional raw water purification switching needs to be connected to the filter element by a water distribution part, which will make the internal structure of the handle complicated and increase product costs. Summary of the invention

[0004] The main technical problem to be solved by the present invention is to provide a raw water to clean water switching mechanism for a water outlet device to increase the water output.

[0005] The secondary technical problem to be solved by the present invention is to provide a raw water to clean water switching mechanism of a water outlet device, which simplifies the assembly structure of the switching valve core and the filter element.

[0006] In order to solve the above technical problems, the present invention provides a raw water and purified water switching mechanism of a water outlet device, comprising a switching component, a water purification component and a housing;

[0007] A raw water flow channel is formed between the housing and the water purification component, and the water purification component is provided with a filter element water inlet and a filter element water outlet, and a purified water flow channel connected between the filter element water inlet and the filter element water outlet;

[0008] The switch member switches between a first position and a second position. When the switch key is in the first position, water passes through the clean water flow channel. When the switch key is in the second position, water does not pass through the clean water flow channel.

[0009] In a preferred embodiment: the switching member includes a first water outlet that is always connected to the raw water flow channel; when the first water outlet is in the first position, it partially overlaps with the water inlet of the filter element, and water passes through the clean water flow channel.

[0010] In a preferred embodiment: the switching member includes a first water outlet that is always connected to the raw water flow channel, and a second water outlet that is connected to or staggered with the water inlet of the filter element.

[0011] In a preferred embodiment: the water inlet of the filter element is arranged on the end surface of the water purification component along the axial direction, and the water inlet of the filter element is in an eccentric position compared to the axial direction.

[0012] In a preferred embodiment: the switching member rotates around the axial direction of the water purification member to switch between the first position and the second position.

[0013] In a preferred embodiment: the water inlet of the filter element is a stepped hole, a circle of grooves is arranged on the outer periphery of the stepped hole, and a sealing gasket for cooperating with the second water outlet is arranged in the groove.

[0014] In a preferred embodiment: the switching member includes a switching valve core and a rotating shell that cooperates with the switching valve core; the rotating shell is rotatably connected to the shell.

[0015] In a preferred embodiment: the switching valve core and the rotating shell are coaxially arranged, the side wall of the switching valve core is provided with a through channel along the radial direction, and a connecting rod passes through the through channel and is fixedly connected to the inner wall of the rotating shell.

[0016] In a preferred embodiment: the inner wall of the rotating shell is provided with two slots along the circumferential direction, and the two slots are respectively connected to one end of the connecting rod; and one end of the slot along the length direction is a non-closed surface.

[0017] In a preferred embodiment: the outer wall of the water purification element is provided with guide ribs along the length direction; the inner wall of the shell is provided with guide grooves that cooperate with the guide ribs.

[0018] The present invention also provides a water outlet device equipped with the raw water and purified water switching mechanism as described above.

[0019] In a preferred embodiment: the water outlet device is a handheld showerhead, and the raw water and purified water switching mechanism is arranged at the handle of the handheld showerhead.

[0020] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0021] 1. The present invention provides a raw water to water purification switching mechanism of a water outlet device. By adding a switching mechanism to the water inlet channel, when in use, the internal switching core shaft is driven to rotate by rotating the outer shell, and the second water outlet of the switching core shaft cooperates with the water inlet of the filter element of the water purification component. When the switching core shaft rotates, when the second water outlet of the switching core shaft is connected to the water inlet of the filter element of the water purification component, part of the water in the water inlet channel goes through the water purification flow channel of the water purification component, and part of the water goes through the raw water flow channel outside the water purification component. When the second water outlet of the switching core shaft is not connected to the water inlet of the filter element of the water purification component, all the water in the water inlet channel goes through the raw water flow channel outside the filter element, so that while achieving the raw water to water purification switching, a small amount of water is allowed to go through the raw water flow channel, increasing the water output, and at the same time extending the service life of the filter element and improving the user experience.

[0022] 2. The present invention provides a raw water purification switching mechanism for a water outlet device, in which the water inlet of the filter element is eccentrically designed so that the second water outlet of the switching valve core directly cooperates with the water inlet of the filter element, reducing intermediate water distribution components, making the structure simple and reducing costs.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0039] In the description of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "mounted / 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 present invention can be understood according to specific circumstances.

[0040] Example 1

[0041] refer to Figure 1-Figure 10 This embodiment provides a handheld shower head, and a raw water and water purification switching mechanism is installed at the handle, so that it has a raw water outlet function and a purified water outlet function. This embodiment takes a handheld shower head as an example, and the raw water and water purification switching mechanism can also be applied to other water outlet devices, which is a simple replacement of this embodiment and will not be repeated.

[0042] The above-mentioned raw water and water purification switching mechanism comprises a switching component 1, a water purification component 2 and a housing 3;

[0043] A raw water flow channel 31 is formed between the housing 3 and the water purification component 2. The water purification component 2 is provided with a filter element water inlet 21 and a filter element water outlet 22, and a purified water flow channel 23 connected between the filter element water inlet 21 and the filter element water outlet 22.

[0044] The switching member 1 switches between a first position and a second position. The switching member 1 includes a first water outlet 11 that is always connected to the raw water flow channel 31 , and a second water outlet 12 that is connected to or staggered from the filter element water inlet 21 .

[0045] Since the first water outlet 11 is always connected to the raw water flow channel, even if the switching mechanism is rotated to connect the second water outlet 12 to the filter element water inlet 21, some water will still flow out from the raw water flow channel. This avoids the problem that all water passes through the water purification unit 2, which causes the water output of the face cover to become weaker and affects the bathing experience.

[0046] In this embodiment, the filter element water inlet 21 is arranged on the end surface of the water purification part 2 along the axial direction, and the filter element water inlet 21 is eccentric compared to the axial direction. The filter element water inlet 21 is designed eccentrically so that the second water outlet 12 of the switching valve core directly cooperates with the filter element water inlet 21, reducing the intermediate water distribution components, making the structure simple and reducing the cost.

[0047] Specifically, in order to cooperate with the eccentric filter element water inlet 21, the switching member 1 rotates around the axial direction of the water purification member 2 to switch between the first position and the second position.

[0048] In order to prevent water from flowing into the filter element water inlet 21 when the second water outlet 12 and the filter element water inlet 21 are offset, the filter element water inlet 21 is a stepped hole, and a circle of grooves are arranged on the outer periphery of the stepped hole, and a sealing gasket 24 for matching with the second water outlet 12 is arranged in the groove. The sealing gasket 24 can seal and isolate the second water outlet 12 from the filter element water inlet 21 when the second water outlet 12 and the filter element water inlet 21 are offset.

[0049] In this embodiment, the switching member 1 includes a switching valve core 13 and a rotating shell 14 that cooperates with the switching valve core 13; the rotating shell 14 is rotatably connected to the housing 3. Specifically, the switching valve core 13 and the rotating shell 14 are coaxially arranged, and a through channel is arranged on the side wall of the switching valve core 13 along the radial direction, and a connecting rod 15 passes through the through channel and is fixedly connected to the inner wall of the rotating shell 14.

[0050] In order to form a linkage fit between the rotating housing 14 and the connecting rod 15, two slots 141 are provided on the inner wall of the rotating housing 14 along the circumferential direction, and the two slots 141 are respectively connected to one end of the connecting rod 15; one end of the slot 141 along the length direction is a non-closed surface. One end of the slot 141 is a closed surface so that the rotating housing 14 can release the linkage fit with the connecting rod 15 when moving along the radial direction, so as to facilitate the assembly of the connecting rod 15 and the rotating housing 14.

[0051] In order to facilitate the installation of the water purification component 2, the outer wall of the water purification component 2 is provided with a guide rib 23 along the length direction; the inner wall of the housing 3 is provided with a guide groove 31 that cooperates with the guide rib 23. The existence of the guide rib 23 ensures that the inner wall of the housing 3 and the outer wall of the water purification component 2 have a certain gap at the position where the guide rib 23 is not provided to form the raw water flow channel.

[0052] Example 2

[0053] refer to Figure 11-Figure 14 The difference between this embodiment and embodiment 1 is that the switching member 1 includes a first water outlet 11 that is always connected to the raw water flow channel; when the first water outlet 11 is in the first position, it partially overlaps with the filter element water inlet 21, and water passes through the clean water flow channel 23. In this way, a solution with only one water outlet is realized, which saves one water outlet compared with the solution of embodiment 1. The rest is the same as embodiment 1 and will not be repeated.

[0054] The above is only a preferred specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the present invention within the technical scope disclosed by the present invention shall be deemed to infringe the protection scope of the present invention.
