The chinese utility model patent with application number 201620241599.2 discloses a water-stopping descaling mechanism and a shower head equipped with the water-stopping descaling mechanism; through the water-stopping descaling framework formed by the descaling part, the connecting bracket, the movable bracket and the top cover, when water is fed each time, the descaling part can move backwards once, and the dirt in the water outlet cover can be ejected out by the needle on the descaling part after the water is shut off, so that the problem of difficult descaling is solved. However, this solution has the following drawbacks: the movable support slides along the water outlet direction on the inner wall of the body, and the smaller the gap between the movable support and the inner wall of the body is, the larger the water pressure borne by the movable support is, so that the movable support is more favorable for driving the descaling part; therefore, in order to ensure that the water pressure born by the movable bracket is enough to drive the descaling part to slide, sliding friction exists in the process that the movable bracket slides relative to the body. Therefore, when the water pressure impacts the movable support to slide along the water outlet direction, the sliding friction force needs to be overcome, and when the water pressure is low, the stability of the movable support driving the descaling part is not facilitated.
In conclusion, the shower head in the prior art still needs to be further improved.

As can be seen from the above description of the present invention, the present invention has the following advantages over the prior art:
1. through set up one in the play water cavity and rotate the swing piece of being connected with the body to set the pressure-bearing face of swing piece to the mode relative with the water gap, make the pressure-bearing face when receiving water pressure and assault, swing piece can drive the scale removal piece of play water intracavity and deviate from first direction and slide, make the scale removal needle on it keep away from the apopore, in order to realize the automatic scale removal of apopore. The principle for realizing the technical effect is as follows: when the water inlet channel does not have water inlet, the descaling piece slides in the first direction under the action of gravity and elastic force in the water outlet cavity, and a descaling needle on the descaling piece penetrates into the water outlet hole; according to the lever principle, when water enters the water inlet channel, the pressure bearing surface at one end of the swinging piece far away from the rotating shaft is impacted by water pressure to rotate downwards, so that one end of the swinging piece close to the rotating shaft is driven to upwards abut against the descaling piece, the descaling piece moves upwards in a direction deviating from the first direction, a descaling needle at the lower surface of the descaling piece is far away from a water outlet hole, and the water outlet hole is communicated with a water outlet cavity, so that the shower head normally discharges water; when the water inlet channel does not have water inlet again, the pressure bearing surface is not impacted by water pressure, the descaling part presses and supports one end of the swinging part close to the rotating shaft, so that the end, provided with the pressure bearing surface, of the swinging part rotates towards the water outlet, and the descaling needle on the swinging part pushes out dirt in the water outlet, and automatic descaling of the water outlet is realized.
In addition, the swinging piece is rotatably connected with the body and is provided with a pressure bearing surface which is opposite to the water passing port and far away from the rotating shaft; therefore, compare in prior art in movable support in the mode of rampart inner chamber sliding connection, the swing piece in this scheme and the setting of body rotation connection are favorable to improving the stability that the swing piece drives descaling piece automatic descaling when water pressure is lower. The principle of achieving this effect is as follows: because the swing piece rotates with the body in this scheme to be connected, consequently at the relative body pivoted in-process of swing piece, the problem that the clearance between the section of thick bamboo wall that does not have a water shutoff section of thick bamboo and the body inner wall can influence the water pressure that the pressure-bearing face bore, swing piece is strikeed and drive the in-process that the scale removal piece deviates from first direction slip by water pressure promptly, and water pressure need not additionally to overcome frictional force.
2. Through set up the mode that the outer stifled water section of thick bamboo of first rampart was located to the cover on the swing piece, the increase is located the water pressure that the bearing surface of stifled water section of thick bamboo bobbin base bore, promotes the swing piece when water pressure is lower, and the drive descaling piece deviates from the gliding stability of first direction, and then avoids the swing piece can't drive the descaling piece when water pressure is lower and slides, influences the condition of the automatic descaling of apopore. The principle for realizing the technical effect is as follows: when water enters the water inlet channel, the plane of the opening of the water plugging barrel is higher than the end face of the first annular wall, and a first water passing gap is formed between the water plugging barrel and the first annular wall, so that water flow can flow into the water outlet cavity by crossing the barrel wall of the water plugging barrel, the water pressure borne by the pressure bearing face is increased, and the effect that the swinging piece is upwards abutted or drives the descaling piece to deviate from the stability of sliding in the first direction is improved.
In addition, when water does not enter the water inlet channel, the descaling needle penetrates into the water outlet hole, and when water enters the water inlet channel, the plane of the cylinder opening of the water blocking cylinder is higher than the end face of the first annular wall, and a first water passing gap is formed between the cylinder opening and the first annular wall; therefore, in the process that the water plugging barrel rotates relative to the body, friction cannot be generated between the barrel wall of the water plugging barrel and the first annular wall, and therefore the situation that the swinging piece cannot drive the descaling piece to slide away from the first direction due to the influence of the friction force between the water plugging barrel and the first annular wall when water enters the water inlet channel and the water pressure is low can be avoided.
3. The plane of the cylinder opening of the water plugging cylinder is arranged to incline towards the rotating shaft and close to the pressure bearing surface, so that when the swinging piece rotates to the limit position relative to the body, the plane of the cylinder opening of the water plugging cylinder can be higher than and parallel to the end surface of the first annular wall; in addition, the arrangement can also avoid the condition that the wall of the water plugging cylinder and the first annular wall interfere with each other in the process that the swinging piece rotates relative to the body.
4. Through the mode that further sets up the second rampart that sets up with first rampart interval in the body, the water pressure that further increase pressure-bearing face bore promotes swinging piece when water pressure is lower, and drive descaling piece deviates from the gliding stability of first direction. The principle for realizing the technical effect is as follows: the end surface of the second annular wall is flush with the end surface of the first annular wall, the water blocking cylinder is sleeved between the first annular wall and the second annular wall, and a second water passing gap is formed between the cylinder opening of the water blocking cylinder and the second annular wall when water enters the water inlet channel; therefore, the water flow can flow into the water outlet cavity after passing through the wall of the water plugging barrel and the second annular wall, so that the water pressure borne by the pressure bearing surface can be increased, and the stability that the swinging piece upwards abuts against or drives the descaling piece to slide away from the first direction is further improved.
In addition, when the water inlet channel is used for water inlet, a second water passing gap is formed between the tube opening of the water blocking tube and the second annular wall; therefore, in the process that the water plugging barrel rotates relative to the body, friction cannot be generated between the barrel wall of the water plugging barrel and the second annular wall, and therefore the situation that when water enters the water inlet channel and the water pressure is low, the water pressure cannot drive the descaling part to slide due to the influence of the friction force between the water plugging barrel and the second annular wall can be avoided.
5. When no water enters the water inlet channel, the bearing surface blocks the water passing hole, so that residual water in the water inlet channel after water is shut cannot flow out of the water outlet hole along the water outlet cavity, and residual water in the water outlet cavity is reduced.
5. When the water inlet channel is arranged and water does not enter, the bearing surface blocks the water passing opening, so that water in the water channel after water is shut cannot enter the water outlet cavity through the water passing opening, and residual water in the water outlet cavity is reduced.
In addition, because the swinging piece is rotationally connected with the body, the problem of pressure relief cannot exist between the water inlet channel and the swinging piece; therefore, the pressure-bearing surface can reduce the residual water in the water outlet cavity only by plugging the water passing port formed on the end surface of the first annular wall, and sealing with the inner wall of the first annular wall is not needed; therefore, the problem that the pressure bearing surface generates friction force with the annular wall to avoid the pressure relief problem in the prior art can be avoided.
6. The water outlet cavity is arranged between the top cover and the water outlet surface cover which are fixedly connected with each other, the water outlet holes are arranged on the water outlet surface cover, and the swinging piece can rotate relative to the body in a mode that the top cover is provided with a rotating hole with an opening facing downwards for the rotating shaft to be arranged.
7. Through the mode of installing a plurality of elastic components between top cap and scale removal spare for the scale removal spare can slide along first direction under the effect of self gravity and elastic component restoring force when the inlet channel does not have water, and make the scale removal needle on it penetrate the apopore.
8. Through set up the projection that supplies elastic component cover to establish on the play water face lid to set up the mode that supplies the through-hole that the projection runs through on the scale removal piece, make the elastic component can fix between top cap and scale removal piece.
9. Through the mode of setting up the bulb subassembly of installing in the top cap for the body can the free rotation, so that use.
10. Through set up the pilot hole that supplies the swing piece to install on the scale removal board to set up the mode that is suitable for supplying the swing arm to keep away from the stopper that the tip of a water shutoff section of thick bamboo upwards pushed up and supports at the pore wall of pilot hole, make the swing piece can drive the scale removal piece and deviate from the first direction and slide when the bearing surface on it is strikeed by water pressure, so that the apopore is kept away from to the scale removal needle.

The opening of the water blocking cylinder 41 of the swinging piece 4 is upward, and the rotating shafts 43 at two sides of the swinging rod 44 are clamped into the two rotating holes 26 from bottom to top from the notches, so that the swinging piece 4 can rotate around the rotating shafts 43 with the extending direction vertical to the first direction relative to the top cover 2; at this time, the swinging member 4 is located in the assembling hole 531 provided on the scale removing member 5, the water blocking cylinder 41 is sleeved outside the first annular wall 21, and one end of the swinging rod 44, which is far away from the water blocking cylinder 41, is located below the limiting block 5311 provided on the hole wall of the assembling hole 531 and is adapted to abut against the limiting block 5311 upwards.
The water outlet cover 6 is fixedly connected below the top cover 2, at this time, 4 convex columns 62 arranged on the upper surface of the water outlet cover just penetrate through 4 through holes 52 arranged on the descaling plate 53, the end surfaces of the convex columns 62 respectively prop against the bottoms of the 4 positioning grooves 29, and 4 elastic pieces are just sleeved outside the 4 convex columns 62.
When water is not boiled, no water is fed into the water inlet channel 24, the descaling part 5 slides in the first direction in the water outlet cavity under the action of gravity and a spring, and a descaling needle 51 on the descaling part penetrates into the water outlet 61; at this time, according to the lever principle, the limiting block 5311 on the descaling part 5 presses the end of the swing rod 44 away from the water plugging cylinder 41 downwards, so that the other end of the swing part 4 provided with the pressure bearing surface 42 pushes upwards and plugs the water passing opening 25; it should be noted that the insertion of the descaling needle 51 into the water outlet 61 herein includes both the case where the descaling needle 51 is inserted into the water outlet 61 and the case where the water outlet 61 is blocked and the case where the water outlet 61 is not blocked, which is not limited in this embodiment.
When water is boiled, water is fed into the water inlet channel 24, one end of the pressure bearing surface 42 arranged on the swinging piece 4 is impacted by water pressure and rotates downwards relative to the top cover 2, and when the swinging piece rotates to the limit position, the plane of the opening of the water blocking cylinder 41 is higher than and parallel to the end surface of the first annular wall 21, and a first water passing gap and a second water passing gap are respectively formed between the plane and the first annular wall 21 and the second annular wall 22; therefore, the water flow flowing out from the water outlet 25 needs to respectively pass through the wall of the water blocking cylinder 41 and the rear part of the second annular wall 22 and can flow into the water outlet cavity, so that the effect of increasing the water pressure borne by the pressure bearing surface 42 and improving the stability of the swinging piece 4 when driving the descaling piece 5 at low pressure is achieved; meanwhile, because the water pressure is greater than the gravity of the descaling part 5 and the acting force of the elastic part 3, the end of the swing rod 44 far away from the water blocking cylinder 41 can upwards prop against the limiting block 5311 to drive the descaling part 5 to slide away from the first direction, so that the descaling needle 51 is far away from the water outlet 61, and water flow can flow out along the water outlet 61 to normally discharge water.
When water is shut off, the water pressure impact on the pressure bearing surface 42 is gradually reduced and is smaller than the self gravity of the descaling part 5 and the restoring force of the elastic part 3, and the limiting block 5311 arranged on the descaling part 5 presses the end of the swinging rod 44 far away from the pressure bearing surface 42 downwards, so that the water blocking cylinder 41 rotates towards the water passing opening 25; when the descaling needle 51 penetrates into the water outlet hole 61, the descaling needle 51 pushes out dirt in the water outlet hole 61, and the pressure bearing surface 42 blocks the water outlet 25, so that automatic descaling of the water outlet hole 61 is realized; furthermore, there is no friction between the oscillating piece 4 and the first annular wall 21, since the oscillating piece 4 slides away from the first direction on being impacted by the water pressure and driving the descaling element 5; therefore, the swinging piece 4 is rotatably connected with the body, so that the stability of the swinging piece 4 for driving the descaling piece 5 to automatically descale when the water pressure is low is improved.
In conclusion, the shower head provided by the invention realizes automatic descaling of the water outlet 61, and has a simple and stable structure.
