Shower

Abstract

The present invention discloses a shower device, wherein a switching component can control a reversing valve core to switch between a normal reversing state and a forced reversing state. When a user does not need a top shower and a hand-held shower to discharge water at the same time, the reversing valve core only needs to be switched to a normal reversing state by the switching component. At this time, the top shower water outlet channel and the hand-held shower water outlet channel and the water inlet channel can be switched and connected by controlling the pause valve core. When the top shower and the hand-held shower need to discharge water at the same time, the reversing valve core can be switched to a forced reversing state by the switching component, and then the top shower and the hand-held shower can be discharged at the same time or the top shower can be discharged alone by controlling the pause valve core. The water channel switching structure is simple, and there is no need to set a complex switching structure between the top shower and the hand-held shower. The pause valve core is set at the hand-held shower, which is convenient to switch. At the same time, there are various water discharge modes, which can discharge water alone or at the same time.

[0041] The top shower 100 is provided with a water inlet channel 110 , a top shower outlet channel 120 , a reversing valve chamber 130 and a flow passage 140 . The water inlet channel 110 is connected with the top shower outlet channel 120 and the flow passage 140 through the reversing valve chamber 130 .

[0042] In this embodiment, the top shower 100 is further provided with a switching chamber 150 which is connected with the reversing valve chamber 130 .

[0043] The reversing valve core 200 is installed in the reversing valve chamber 130 and has a normal reversing state and a forced reversing state.

[0044] In this embodiment, the reversing valve core 200 includes a reversing valve shaft 210, a reversing valve body 220, a reversing sealing gasket 230 fixedly connected to both ends of the reversing valve shaft 210, and a deformation portion 240. The reversing valve body 220 is fixedly connected to the reversing valve cavity 130 and is provided with a reversing inlet 221 connected to the water inlet channel 110. The reversing valve body 220 is provided with an active cavity 222 that penetrates the reversing valve body 220 and is connected to the reversing inlet 221. The reversing valve shaft 210 can move along the length direction of the active cavity 222, and the reversing sealing gasket 230 and the deformation portion 240 are respectively located at both ends of the active cavity 222. ; The normal reversing state includes the reversing sealing gasket 230 leaving the opening of the active cavity 222 located on the side of the reversing sealing gasket 230 and the deformation part 240 sealing the opening of the active cavity 222 located on the side of the deformation part 240, or the reversing sealing gasket 230 seals the opening of the active cavity 222 located on the side of the reversing sealing gasket 230 and the deformation part 240 leaves the opening of the active cavity 222 located on the side of the deformation part 240, and the forced reversing state is the reversing sealing gasket 230 leaving the opening of the active cavity 222 located on the side of the reversing sealing gasket 230 and the deformation part 240 leaving the opening of the active cavity 222 located on the side of the deformation part 240.

[0045] In this embodiment, the reversing valve core 200 further includes a reversing elastic member 250, which is pressed against between the reversing valve shaft 210 and the reversing valve body 220. Specifically, the reversing elastic member 250 is sleeved outside the reversing sealing gasket 230, and its two ends are pressed against the end of the reversing valve shaft 210 located on the reversing sealing gasket 230 side and the cavity wall of the active cavity 222 respectively.

[0046] In this embodiment, the reversing valve shaft 210 is provided with a positioning portion; Figure 4 As shown, the positioning portion is a positioning socket 211 and corresponds to the reversing inlet 221. Figure 7 As shown, the positioning hole 211 is located in the middle of the reversing valve shaft 210 and between the reversing seal 230 and the deforming portion 240. In this embodiment, the end surface of the positioning hole 211 facing the switching shaft is provided with a guiding inclined surface 212 for facilitating the switching shaft to be inserted into the positioning hole 211.

[0047] The switching assembly 300 is installed on the top shower head 100 , and can control the reversing valve core 200 to switch between a normal reversing state and a forced reversing state.

[0048] In this embodiment, the switching assembly 300 includes a switching shaft 310 that can move relative to the top shower 100. The switching shaft 310 moves between a departure position away from the positioning portion and a positioning position that is positioned and matched with the positioning portion. When the switching shaft 310 is in the positioning position, the reversing valve shaft 210 is fixed so that the reversing valve core 200 is in a forced reversing state. When the switching shaft 310 is in the departure position, the reversing valve shaft 210 can move under the action of water pressure so that the reversing valve core 200 is in a normal reversing state.

[0049] In this embodiment, the end of the switching shaft 310 passes through the reversing inlet 221 and matches with the positioning socket 211 .

[0050] In this embodiment, the moving direction of the switching shaft 310 is perpendicular to the moving direction of the reversing valve shaft 210, so that the positioning and matching between the switching shaft 310 and the reversing valve shaft 210 is faster and more stable. As required, the moving direction of the switching shaft 310 and the moving direction of the reversing valve shaft 210 can be designed to be non-perpendicular, such as an acute angle or an obtuse angle, but the present invention is not limited thereto.

[0051] In this embodiment, the switching assembly 300 also includes a switching seat 320, a switching button 330, an upper gear shaft 340, a lower gear shaft 350 and a switching elastic member 360. The switching seat 320 is fixedly connected in the switching cavity 150, and the switching button 330 is movably mounted on the switching seat 320. The upper gear shaft 340 is located in the switching seat 320 and is in transmission cooperation with the switching button 330 and the lower gear shaft 350. The lower gear shaft 350 is in transmission cooperation with the switching shaft 310. The end of the switching shaft 310 extends into the reversing valve cavity 130, and the switching elastic member 360 is pressed against between the switching shaft 310 and the switching cavity 150. The switching principle of the switching assembly 300 is the same as the switching principle of the ballpoint pen core, which will not be repeated. It is worth mentioning that a switching sealing gasket 370 is provided between the upper gear shaft 340 and the switching seat 320 to ensure that water does not flow out of the switching seat 320.

[0052] The hand shower 400 has a hand shower outlet channel 410 connected to the flow channel 140. Figure 2 As shown, the hand shower 400 is connected to the top shower 100 via a hose 420 , that is, the hose 420 is connected through the flow channel 140 and the hand shower water outlet channel 410 .

[0053] The pause valve core 500 is installed on the hand shower 400 to open or close the hand shower water outlet channel 410 .

[0054] In this embodiment, the handheld showerhead 400 is further provided with a pause valve chamber 430, the pause valve chamber 430 is provided with a pause inlet 431 connected to the front end of the handheld showerhead water outlet channel 410 and a pause outlet 432 connected to the rear end of the handheld showerhead water outlet channel 410, the pause valve core 500 includes a pause valve shaft 510 movably mounted on the pause valve chamber 430 and a pause sealing gasket 520 fixedly connected to the pause valve shaft 510, and the pause sealing gasket 520 moves between a sealing position for sealing the pause outlet 432 and an opening position for opening the pause outlet 432.

[0055] In this embodiment, Figure 8 As shown, the pause valve cavity 430 passes through the hand shower 400 vertically, and the pause valve core 500 further includes a first pause button 530 and a second pause button 540 , which are respectively fixed to the upper and lower ends of the pause valve shaft 510 .

[0056] The working principle of the pause valve core 500 is as follows: Figure 8 As shown, pressing the second button 540 upward drives the pause valve shaft 510 and the pause sealing gasket 520 to move upward synchronously until the pause sealing gasket 520 moves to the sealing position of the sealing pause outlet 432. At this time, the front end of the hand-held shower water outlet channel 410 is disconnected from the rear end of the hand-held shower water outlet channel 410; Fig.12 As shown, pressing the first pause button 530 downward drives the pause valve shaft 510 and the pause sealing gasket 520 to move downward synchronously until the pause sealing gasket 520 moves to the open position of opening the pause outlet. At this time, the front end of the handheld shower water outlet channel 410 is connected to the rear end of the handheld shower water outlet channel 410.

[0057] There are four water outlet modes for this shower device:

[0058] The first water outlet method is as follows Figures 6 to 9 Shown:

[0059] like Fig. 9 As shown, when the switching shaft 310 is in the leaving position, that is, when it leaves the positioning socket 211, there is no connection relationship between the switching assembly 300 and the reversing valve core 200, and they are independent of each other. The reversing valve core 200 is the same as the ordinary reversing valve core. The reversing valve shaft 210 can move under the action of water pressure, so that the reversing valve core 200 is in a normal reversing state; Figure 8 As shown, the pause seal 520 is in the sealing position so that the hand shower water outlet channel 410 is closed;

[0060] like Figure 7As shown, the water pressures on the left and right ends of the deformation part 240 are the same, the deformation part 240 maintains a normal open state and seals the entrance of the flow channel 140, and the water pressure on the right end of the reversing seal 230 is greater than the water pressure on the left end of the reversing seal 230, so that the reversing valve shaft 210 is subjected to the left force and moves to the left, and the reversing seal 230 leaves the opening of the active chamber 222 on the side of the reversing seal 230, and the deformation part 240 just seals the opening of the active chamber 222 on the side of the deformation part 240, and the reversing elastic member 250 keeps the reversing valve shaft 210 in this position, and water enters from the water inlet channel 110 and then enters the active chamber 222 from the reversing inlet 221, and then flows from the opening of the active chamber 222 on the side of the reversing seal 230 to the top shower outlet channel 120, and the top shower outlet channel 120 discharges water;

[0061] The second water outlet method is as follows Figures 10 to 12 As shown:

[0062] The switching shaft 310 is in the same position as the first water outlet mode, and is located in the away position, so that the reversing valve core 200 is in a normal reversing state; Fig.12 As shown, the pause seal 520 is in the open position so that the hand shower water outlet channel 410 is opened;

[0063] like Fig.11 As shown, the water pressure in the flow passage 140 is released, and the water pressure on the left end of the deformation part 240 is greater than the water pressure on the right end, so that the deformation part 240 is subjected to a rightward force to drive the reversing valve shaft 210 and the reversing sealing gasket 230 to move rightward, and the reversing sealing gasket 230 is sealed at the opening of the active chamber 222 located on the side of the reversing sealing gasket 230, and the deformation part 240 leaves the opening of the active chamber 222 located on the side of the deformation part 240, and the right end of the deformation part 240 is deformed and contracted inward to reduce its diameter until the entrance of the flow passage 140 is opened, and the reversing elastic member 250 is compressed. After entering from the water inlet channel 110, water enters the active chamber 222 from the reversing inlet 221, and then flows from the opening of the active chamber 222 located on the side of the deformation part 240 to the flow passage 140, and enters the hand-held shower outlet channel 410 after passing through the hose 420, and the hand-held shower outlet channel 410 discharges water;

[0064] The third water outlet method is as follows Fig.13 and Fig.15 As shown:

[0065] like Fig.15, the switching shaft 310 is located at the positioning position, that is, inserted into the positioning plug hole 211, the reversing valve shaft 210 is limited by the switching shaft 310 and is fixed. No matter how the water pressure changes, the reversing valve shaft 210 always maintains the same position. The reversing valve core 200 is in a forced reversing state, the reversing sealing gasket 230 leaves the opening of the active chamber 222 located on the side of the reversing sealing gasket 230, and the deformation part 240 leaves the opening of the active chamber 222 located on the side of the deformation part 240; the valve core 500 is paused and Fig.12 The state is the same, the sealing gasket 520 is in the open position, and the hand shower water outlet channel 410 is opened;

[0066] like Fig.14 As shown, part of the water in the water inlet channel 110 flows from the opening of the active cavity 222 on the side of the reversing seal 230 to the top shower water outlet channel 120, and the deformable portion 240 contracts inwardly under the water pressure to open the entrance of the flow channel 140, and another part of the water in the water inlet channel 110 flows from the opening of the active cavity 222 on the side of the deformable portion 240 to the flow channel 140, and water is discharged from the top shower water outlet channel 120 and the flow channel 140;

[0067] The fourth water outlet method is as follows Fig.16 and Fig.17 As shown:

[0068] The position of the switching shaft 310 is Fig.15 The position in the same, in the positioning position, the reversing valve core 200 is in a forced reversing state, and the valve core 500 is suspended. Figure 8 Same, pause the sealing gasket 520 in the sealing position;

[0069] like Fig.17 As shown, water in the water inlet channel 110 flows from the opening of the active cavity 222 located on the side of the reversing sealing gasket 230 to the top shower water outlet channel 120 , and water flows out of the top shower water outlet channel 120 .

[0070] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
