Description

TECHNICAL FIELD

[0001] The present application relates to bathroom products, in particular to a top spray shower. BACKGROUND

[0002] The existing shower often has residual water not completely discharged after the user uses it, so that the shower suddenly flows out when it encounters shaking or collision, causing unnecessary trouble, or causing the residual water to spray towards the human body when the user opens the shower, greatly affecting the user's experience, and the residual water that cannot be discharged in time usually contains many impurities and bacteria, which may affect the user's health when sprayed towards the human body, reducing the safety and practicality of the shower.

[0003] Based on this, there are showers on the market that can discharge residual water after the water is turned off. However, the existing residual water discharge function has the following problems:

[0004] First, after the water is turned off, no external air is introduced into the cavity, which easily causes a vacuum inside the cavity, making it difficult to discharge residual water, and there is a continuous dripping phenomenon near the fast discharge hole outlet when fast discharging.

[0005] Second, the shower needs to be placed at an angle after the water is turned off to allow the residual water to flow out.

[0006] Third, in addition to the residual water flowing out from the fast discharge hole, part of the residual water also enters the water outlet hole and drips slowly, causing a continuous dripping phenomenon. SUMMARY

[0013] In a preferred embodiment: the movable element abuts against a third reset spring; during the movement of the movable element from the first position to the second position, the third reset spring accumulates elastic reset force.

[0014] In a preferred embodiment: the top spray shower head comprises a water outlet surface cover, one side of the water outlet surface cover is provided with a residual water outlet communicating with the residual water quick drainage hole; the water outlet surface cover is provided with a water outlet hole, the water outlet hole is divided into a first water outlet hole close to the residual water outlet and other water outlet holes, the first water outlet hole protrudes inward from the water outlet surface cover by a height higher than that of the other water outlet holes.

[0015] In a preferred embodiment: the top spray shower head is provided with a fixing seat, the fixing seat is provided with a connecting seat matched with the ball head, and the rear cover of the top spray shower head is provided with a first accommodation opening through which the connecting seat passes.

[0016] In a preferred embodiment: the connecting seat is connected with a nut through external threads, and a semi-encircling bushing is arranged between the nut and the ball head; when the top spray shower head is in a horizontal position, the bushing and the ball head are limitingly matched in a counterclockwise direction.

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

[0021] This invention provides a top-spray shower head that drains residual water. A through hole is provided in the fixed base connecting the quick-drain hole for residual water and the air inlet. When water is supplied, the movable component, under water pressure, drives the first and second switching shafts to move against the spring force, causing the two switching shafts to seal the quick-drain hole for residual water and the air inlet respectively, so that both the quick-drain hole for residual water and the air inlet are in a closed state. At this time, the top-spray shower head dispenses water normally. When the water is turned off, the water pressure disappears, the movable component resets under the action of the third spring, and the pressure between the movable component and the two switching shafts disappears. The two switching shafts reset under the action of the springs, and at this time, the drain hole for residual water and the air inlet open. The residual water draining chamber introduces a large amount of external air, making the pressure inside and outside the chamber equal, thus achieving the purpose of draining residual water when the top-spray shower head is in a horizontal position.

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application.

In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0034] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "provided with", "sleeved / connected", "connected" and the like should be understood broadly, for example, "connected" can be wall-mounted connection, can be detachable connection, or integral connection, can be mechanical connection, can be electrical connection, can be direct connection, can be indirect connection through an intermediate medium, can be internal communication of two elements, and for a person of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0035] With reference to Figures 1-11 The present embodiment provides a top-spraying shower for draining residual water, comprising: a movable part 11 affected by water pressure, an air inlet hole 12 and a residual water quick-draining hole 13 provided on the top-spraying shower 1, a first sealing part 14 and a second sealing part 15 provided in the top-spraying shower 1 for opening or sealing the air inlet hole 12 and the residual water quick-draining hole 13;

[0036] The movable part 11 is moved from a first position to a second position when water is flowing, and drives the first sealing part 14 and the second sealing part 15 to block the air inlet hole 12 and the residual water quick-draining hole 13; the movable part 11 is moved from the second position to the first position when water is turned off, so that the first sealing part 14 and the second sealing part 15 are reset to open the air inlet hole 12 and the residual water quick-draining hole 13.

[0037] The top spray shower 1 of the above-mentioned residual water discharging type is provided with an air inlet hole 12 and a residual water discharging hole 13, and when water is supplied, the two holes are closed respectively. When water is cut off, the two holes are opened automatically. Thus, when the top spray shower 1 is in a horizontal state, the residual water discharging cavity is filled with air, so that the pressure in the cavity is equal to the pressure outside the cavity, and the residual water can be discharged.

[0038] When the movable member 11 moves from the first position to the second position, the first sealing member 14 and the second sealing member 15 also move. The movement direction of the movable member 11 is determined by the water pressure, and is along the axial direction of the top spray shower 1. If the movement direction of the first sealing member 14 and the second sealing member 15 is also along the axial direction of the top spray shower 1, the thickness of the top spray shower 1 will be greatly increased, and the appearance of the shower will be not beautiful. Therefore, in the embodiment, the movement direction of the first sealing member 14 and the second sealing member 15 is perpendicular to the axial direction of the top spray shower 1. Thus, the internal space of the top spray shower 1 can be used for the movement of the first sealing member 14 and the second sealing member 15 in the horizontal plane of the top spray shower 1, and the thickness of the top spray shower 1 does not need to be increased for the movement of the first sealing member 14 and the second sealing member 15. Since the movement directions of the movable member 11, the first sealing member 14 and the second sealing member 15 are different, the first sealing member 14 and the second sealing member 15 are connected to the movable member 11 through a reversing structure, so as to reverse the movement of the movable member 11 along the axial direction of the top spray shower 1 to the movement of the first sealing member 14 and the second sealing member 15 along the direction perpendicular to the axial direction of the top spray shower 1.

[0039] In order to realize the above-mentioned reversing connection, the first sealing member 14 and the second sealing member 15 are sealing rings arranged on the first switching shaft 16 and the second switching shaft 17 respectively, and the first switching shaft 16 and the second switching shaft 17 are connected to the movable member 11 through inclined surfaces. Thus, when the movable member 11 moves from the first position to the second position, the inclined surfaces 111 on both sides of the movable member 11 will be pressed against the inclined surfaces 161 and 171 on the end surfaces of the first switching shaft 16 and the second switching shaft 17 respectively, so as to drive the first switching shaft 16 and the second switching shaft 17 to move in opposite directions along the direction perpendicular to the axial direction of the top spray shower 1.

[0040] The above structure can only realize that the first switching shaft 16 and the second switching shaft 17 drive the first sealing member 14 and the second sealing member 15 to block the air inlet hole 12 and the residual water quick discharge hole 13. In order to realize automatic discharge of residual water, the air inlet hole 12 and the residual water quick discharge hole 13 need to be automatically opened when the water is turned off. For this purpose, the first switching shaft 16 and the second switching shaft 17 are respectively sleeved with a first reset spring 162 and a second reset spring 172, and the first reset spring 162 and the second reset spring 172 accumulate elastic reset force when the first sealing member 14 and the second sealing member 15 block the air inlet hole 12 and the residual water quick discharge hole 13. In this way, when the movable part 11 moves from the second position to the first position when the water is turned off, the extrusion force between the inclined surface of the movable part 11 and the first switching shaft 16 and the second switching shaft 17 disappears, and the first switching shaft 16 and the second switching shaft 17 will automatically move towards each other under the action of the elastic reset force of the first reset spring 162 and the second reset spring 172, thereby opening the air inlet hole 12 and the residual water quick discharge hole 13.

[0041] In addition, in order to realize that the movable part 11 can automatically reset to the first position after the water pressure disappears when the water is turned off, the movable part 11 abuts against a third reset spring 112, and the third reset spring 112 accumulates elastic reset force during the movement of the movable part 11 from the first position to the second position. In this way, after the water is turned off, the water pressure disappears, and the third reset spring 112 releases the elastic reset force, which can drive the movable part 11 to reset from the second position to the first position.

[0042] In the embodiment, in order to install the first switching shaft 16, the second switching shaft 17 and the movable part 11, the top spray shower 1 is provided with a fixing seat 18, and the fixing seat 18 includes a first mounting cavity 181 extending along the axial direction of the top spray shower 1, and a second mounting cavity 182 extending along the vertical direction of the top spray shower 1;

[0043] The movable part 11 is arranged in the first mounting cavity 181, the first switching shaft 16 and the second switching shaft 17 are arranged in the second mounting cavity 182, and the two ends of the second mounting cavity 182 are respectively provided with the air inlet hole 12 and the residual water quick discharge hole 13; when the movable part 11 moves from the first position to the second position when the water is turned on, the first sealing member 14 and the second sealing member 15 block the air inlet hole 12 and the residual water quick discharge hole 13, respectively.

[0044] In this embodiment, one side of the water outlet surface cover 19 of the top spray shower 1 is provided with a residual water outlet 193 communicating with the residual water quick drain hole 13; the water outlet surface cover 19 is further provided with water outlet holes, which are divided into first water outlet holes 191 close to the residual water outlet 193 and other water outlet holes 192, and the height of the first water outlet holes 191 protruding inward from the water outlet surface cover is higher than that of the other water outlet holes 192. After such arrangement, the height of the water outlet holes close to the residual water outlet is higher than that of the other water outlet holes, so that when residual water is drained, even if the water is not completely drained, the user still cannot cause the residual water to drop when patting the top spray shower 1, and it can be ensured that the residual water will not continuously drop.

[0045] In order to further facilitate the user to use the top spray shower 1, the fixing seat 18 is provided with a connecting seat 183 matched with the ball head 2, and the rear cover 10 of the top spray shower 1 is provided with a first accommodating opening 101 through which the connecting seat 183 passes. Through the cooperation of the connecting seat 183 and the ball head 2, the use angle of the top spray shower 1 can be adjusted. In this way, the user can not be limited to using the top spray shower 1 in the horizontal state. However, after the top spray shower 1 is swung, it is possible that the side of the top spray shower 1 provided with the residual water quick drain hole 13 is upwardly tilted, which will cause the residual water to be unable to be drained. In order to avoid this situation, it is necessary to limit the swinging direction of the top spray shower 1, so that the side of the top spray shower 1 provided with the residual water quick drain hole 13 cannot be swung upwardly at the horizontal position. Therefore, the connecting seat 183 is connected with a nut 184 through external threads, and a half-enclosing bushing 3 is arranged between the nut 184 and the ball head 2. When the top spray shower 1 is located at the horizontal position, the bushing 3 is limitedly matched with the ball head 2 in the counterclockwise direction. Thus, the user can only swing the residual water quick drain hole 13 downwardly at the horizontal position, avoiding the user's misoperation. At the same time, in addition to the swing connection between the top spray shower 1 and the ball head 2, the top spray shower 1 can also rotate around the ball head 2, so that the user can place the quick drain hole at any position along the circumferential direction as desired.

[0046] In this embodiment, the bushing 3 has a gap 31 along the circumferential direction, and the gap 31 cooperates with the flange 185 on the fixing seat 18, so that the bushing 3 and the fixing seat 18 are relatively stationary in the rotation direction. In this way, the residual water outlet 193 can only be located at one side of the fixing seat 18 and cannot be rotated to the other side. The half-enclosing arrangement of the bushing 3 can make the side where the residual water outlet 193 is located only swing downwardly along the horizontal plane, avoiding the situation that the residual water outlet 193 swings upwardly to cause the residual water drainage function to fail.

[0047] The above merely describes preferred specific embodiments of the present application, but the design concept of the present application is not limited thereto, and any person skilled in the art, within the technical scope disclosed by the present application, can make non-essential modifications to the present application using the concept, and such modifications shall not be deemed to be within the scope of the present application.
