The working principle and the beneficial effects of the technical scheme are as follows:
the first rotating shaft 31 slides downwards along the support plate 32, the second sliding block 49 slides in the sliding groove 48 to limit the first rotating shaft 31, so that the first rotating shaft 31 is prevented from rotating when sliding downwards, the first rotating shaft 31 slides downwards in the shaft hole of the second rotating shaft 40, and the limiting block 47 is clamped with the limiting groove 42 at the side end of the shaft hole of the second rotating shaft 40, so that the first rotating shaft 31 is clamped with the second rotating shaft 40; when the sliding groove 48 slides to the top end to contact with the second sliding block 49, the second sliding block 49 enters the annular sliding groove 50, and the limit on the first rotating shaft 31 is released, so that the first rotating shaft 31 can rotate; after the guide plate 39 is opened, the collected liquid flows in the direction of the guide plate 39, the collected liquid drives the fan blades 34 on the bearing plate 33 to rotate, so that the first rotating shaft 31 rotates synchronously, the second rotating shaft 40 is driven to rotate, the first bevel gear 41 rotates synchronously, the first bevel gear 41 and the second bevel gear 46 are in meshed transmission, the second bevel gear 46 is driven to rotate around the second rotating shaft 40, and as the second bevel gear 46 is connected with the spray pipe 44, the spray pipe 44 is driven to rotate in the spray pipe chute 43, and a part of collected liquid water flows vertically downwards through the spray pipe 44 and is close to a liquid outlet at the bottom of the collection cavity 13.
Through above-mentioned structural design, adopt spray tube 44 to spray the liquid collection operation of realizing to gather near the liquid outlet of chamber 13 bottom, avoid part to gather the liquid and volatilize under the effect of air current, lead to the condition that the aerosol granule that has entered into in gathering the liquid overflows again, improve collection efficiency, and spray tube 44 is in along with spraying seat 5 rotation spraying, can realize the rotation, continuously change the relative position of spray tube 44 and deflector 39 spout, when guaranteeing that the less side wall liquid collection outflow that does not influence of size, spray to whole bottom liquid outlet, improve and spray the effect of liquid collection, avoid producing single position and spray the liquid collection, another position volatile condition.
Example 7:
as shown in fig. 9, in the above embodiment 5, the baffle 39 is connected to the fourth rotating shaft 57 at the bottom end of the shower base 5, and the baffle 39 includes:
the upper groove 51 is formed in the top end of the guide plate 39, the third slider 52 is connected in a sliding manner in the upper groove 39, the second spring is connected between the third slider 52 and the bottom end of the upper groove 51, the communication port 54 is formed in the side end of the upper groove 51, and the communication port 54 is blocked when the third slider 52 is not pressed;
the top block 53, the top block 53 is connected to the top end of the third slider 52 and contacts the second pressing plate 38;
the pressure cavity 55 is arranged in the guide plate 39, the first magnetic block 56 is connected in a sliding manner in the pressure cavity 55, the third spring is connected to one end, away from the fourth rotating shaft 57, of the first magnetic block 56 and the pressure cavity 55, and one side, away from the fourth rotating shaft 57, of the pressure cavity 55 is connected with the communication port 54 through a pipeline;
the magnetic block two 58 is connected to the side end of the fourth rotating shaft 57 at a position below the side end, and after the guide plate 39 rotates downwards to a preset angle, the magnetic block one 56 and the magnetic block two 58 are attracted.
The working principle and the beneficial effects of the technical scheme are as follows:
the second pressing plate 38 contacts with the top block 53, when the second pressing plate 38 moves downwards, the top block 53 is pressed until the second pressing plate 38 contacts with the protrusion of the guide plate 39, after contact, a gap is formed between the second pressing plate 38 and the upper groove 51, the collected liquid water flow can flow into the upper groove 51 through the gap, at this time, the top block 53 slides downwards along the inner wall of the upper groove 51 to expose the communication port 54, the communication port 54 is communicated with the upper part of the upper groove 51, the collected liquid water flow enters into the pressure cavity 55 along the pipeline, the first pressing magnet 56 slides towards the direction approaching to the fourth rotating shaft 57, the pressure cavity 55 gradually approaches to the second pressing magnet 58 along with the rotation expansion of the guide plate 39, the first pressing magnet 56 and the second pressing magnet 58 attract each other, and the guide plate 39 keeps stable. When the pressure of the collected liquid water flow fluctuates slightly, the second pressing plate 38 shakes, and the guide plate 39 cannot overcome the attractive force of the first magnetic block 56 and the second magnetic block 58, so that the stable state is kept continuously; when the collection is finished, the water flow pressure of the collection liquid disappears, the second pressing plate 38 is reset rapidly, the first magnetic block 56 is reset under the action of the third spring to push out the collection liquid, and the top block 53 is reset under the action of the second spring.
Through the above-mentioned structural design, after the guide plate 39 expands, the rivers pressure produces small fluctuation and still can keep steady state, make the collection liquid rivers can be along guide plate 39 stable outflow, make rivers angle keep preset value, avoid producing the unstable circumstances that leads to rivers angle to change unable and aerosol granule fully contact of pressure, and just can make magnetic path one 56 and block two 58 attract each other under the combined action of clamp plate two 38 and rivers and keep steady state, the unexpected circumstances that can't reset of expansion of guide plate 39 when effectively avoiding receiving the vibration, the reliability of device has been improved.
