The water stop 20 is movably provided in the body 10 and is movable between a closed position closing the water inlet 121 and an open position opening the water inlet 121. The water stop 20 is movable from a closed position to an open position by the water pressure of the water in the water inlet passage 11, and is capable of being returned from the open position to the closed position when the water inlet passage 11 is shut down. When the water stop piece 20 closes the water inlet 121, negative pressure is formed in the water outlet cavity 12, and water in the water outlet cavity 12 is adsorbed in the water outlet cavity 12 through the negative pressure, so that the problem of water dripping or a large amount of water dripping after water stopping of the shower can be effectively avoided. Because the water stop 20 only needs to be matched with the water inlet 121 in an opening and closing manner, the water stop 20 can be designed to be smaller, the driving force for driving the water stop 20 is smaller, the consumption of water inlet pressure is smaller, the influence on water outlet pressure is smaller, and the purpose of preventing water dripping can be effectively achieved under the condition of lower water inlet pressure.

In this embodiment, the water stop 20 is made of rubber material, and has an elastic force, and the water stop 20 is reset from the open position to the closed position under the combined action of the elastic force of the water stop 20 and the elastic force of an elastic member 30. The elastic member 30 is specifically a compression spring. In other embodiments, the elastic member 30 may not be provided, and the water stop member 20 may be returned from the open position to the closed position only by the elastic force of the water stop member, or the water stop member 20 may not have elasticity, and the water stop member 20 may be returned from the open position to the closed position only by the elastic force of an elastic member. In other embodiments, the water stop 20 may be returned from the open position to the closed position by a combination of its own elastic force and a magnetic attraction force of a magnetic member (not shown).

In this embodiment, the water stop 20 includes a water stop 21, a deformation portion 22 and a connection portion 23 connected in sequence, the deformation portion 22 surrounds the outer ring of the water stop 21, the connection portion 23 surrounds the outer ring of the deformation portion 22, the outer edge of the deformation portion 22 is connected with the inner edge of the connection portion 23, the inner edge of the deformation portion 22 is connected with the outer edge of the water stop 21, the water stop 21 is matched with the water inlet 121 in an opening and closing manner, the connection portion 23 is fixed on the body 10, and the deformation portion 22 is deformable. The water stop 20 thus designed is simple in structure, convenient to install, and reliable in function of opening and closing the water inlet 121.

In this embodiment, the water stopping portion 21 is a water stopping disc, the front surface of the water stopping disc is matched with the water inlet 121, the back surface of the water stopping disc is abutted against the elastic member 30, the elastic member 30 drives the water stopping disc to move from the open position to the closed position, and the front surface of the water stopping disc is acted by water inlet pressure when the water inlet channel 11 is filled with water.

In this embodiment, the gasket 40 is disposed on the back of the water stop disc, the elastic member 30 is a compression spring, one end of the compression spring is abutted against the body 10 or a component fixed relative to the body 10, and the other end of the compression spring is abutted against one side of the gasket 40 facing away from the water stop disc.

Specifically, the body 10 includes a housing 13 and a water passing body 14 fixedly disposed in the housing 13, the water passing body 14 has a water passing cavity 141, the water inlet channel 11 is communicated with the water outlet cavity 12 through the water passing cavity 141, the water inlet 121 is disposed between the water passing cavity 141 and the water outlet cavity 12, and the water stop 20 is disposed in the water passing cavity 141.

More specifically, the water passing body 14 includes a first water passing body 142 and a second water passing body 143, the first water passing body 142 and the second water passing body 143 enclose a water passing cavity 141, and the first water passing body 142 and the second water passing body 143 are fixedly connected to clamp the connecting portion 23.

In this embodiment, the body 10 includes a water outlet panel 15, a plurality of water outlets 122 are distributed on the water outlet panel 15, and each water outlet 122 is provided with a water outlet nozzle 50 made of soft material. The water spouts 50 are connected to form a water spout integrated plate.

The shower head of the utility model can be a top shower head, a hand shower head or the like, and the embodiment is specifically a top shower head.

The specific working principle is as follows:

Referring to fig. 3 and 4, at this time, in a normal state when the shower head is not in use, since there is no water pressure in the water inlet channel 11, the water stop member 20 is positioned at a position to close the water inlet 121 under the action of the self elastic force and the elastic force of the elastic member 30, at this time, a negative pressure is formed in the water outlet chamber 12, and residual water in the water outlet chamber 12 is adsorbed without flowing out under the action of the negative pressure.

Referring to fig. 5 and 6, at this time, in the use state of the shower head, the water flow pressure in the water inlet channel 11 acts on the water stop 20, and the water stop 20 moves from the closed position closing the water inlet 121 to the open position opening the water inlet 121 against the self elastic force of the water stop 20 and the elastic force of the elastic member 30, so that the water flow of the water inlet channel 11 flows into the water outlet cavity 12 and flows out of the water outlet 122 of the water outlet cavity 12.

When the water inlet channel 11 is cut off, the water stop member 20 moves to the closed position under the action of the self elastic force and the elastic force of the elastic member 30 because no water inlet water pressure exists in the water inlet channel 11, so that the communication between the water inlet channel 11 and the water outlet cavity 12 is cut off, negative pressure is formed in the water outlet cavity 12, residual water in the water outlet cavity 12 can be adsorbed and not flow out under the action of the negative pressure, and the shower head returns to the normal state of fig. 3 and 4.
