Improved structure for switching buttons of shower
Technical Field
The invention relates to the technical field of bathrooms, in particular to an improved structure for switching buttons of a shower head.
Background
The button switching structure in the bathroom industry pushes a pull rod connected with a driving disc through a button, so that a driven disc above or below is driven, and then a water sealing disc is driven to rotate, and the switching of the water spray function is realized.
The CN201420658855 discloses a button control water outlet terminal mechanism, which adopts a link mechanism consisting of a push block and a pull rod, and is characterized in that the button drives a driven switching component to realize water flow switching in a linkage way through the link mechanism, and the button specifically acts as: the push button is pressed down, the push block is pushed, the push rod can pull the pull rod backwards, the pull rod is in linkage (rotation) with the driving disc, the driving disc and the driven disc are in an upper layer and a lower layer, 4 tooth surfaces are arranged on the driving disc and are matched with the driven disc, and the driving disc rotates to drive the driven disc and the water sealing disc below to rotate, so that function switching is realized. When in reset, the tension spring directly pulls the driving disc to reset, and the driving disc can float upwards to be separated from the driven disc due to the cooperation of the tooth surface in the reset process.
The defects are that: 1. the pull rod is connected with the driving disc and needs to be fixedly connected, and when in action, the pull rod is easy to deform and even has the problem of clamping, so that the switching is not smooth; 2. the driving disc and the driven disc are arranged up and down and have larger height space, so that the thickness of the shower body is required to be larger, and the whole product is made.
U.S. patent 6622945 discloses a gondola water faucet structure, the switching structure that this gondola water faucet structure was last to set up directly promotes a telescopic locating piece through pressing the pendulum rod and drives fluted disc (driven plate) rotation, thereby realize rivers switching, this switching structure's locating piece drives driven plate pivoted effort not the tangential force on the driven plate direction of rotation, but promote along straight line or slash and get into driven plate ratchet, a component when the driven plate can only obtain the pendulum rod motion, moreover the locating piece can not keep always laminating with the ratchet straight face, lead to this switching structure to need great exogenic action just can operate, moreover the atress is unstable, the operation degree of difficulty is big.
CN201621422830 also discloses a gondola water faucet push rod switches out water structure, including fixing base, pull rod, push rod, connecting axle, ratchet (initiative dish), pawl (driven plate) and carousel (seal surface of water lid), it drives the pull rod through the push rod and removes along the horizontal direction, and the sideslip of pull rod converts into the axial rotation of ratchet, and the ratchet drives the pawl again and rotates to drive connecting axle and carousel rotation, the carousel rotates the water diversion hole (formation on seal surface of water lid) that makes its water hole correspond, realizes out water function switching. The structure specifically utilizes the elastic claw part on the ratchet matched pawl of the ratchet inner ring to achieve the aim of synchronous rotation of the ratchet and the pawl, the elastic claw part deforms when the ratchet rotates to reset to avoid the reset of the pawl, the elastic claw part is matched with the next ratchet to achieve the aim of non-return after the ratchet resets, and the switching water outlet structure has the defects that: 1) The whole product is driven to move through the pull rod, so that the operation and the control are inconvenient; 2) The elastic claw part is deformed and is easy to block when the ratchet wheel is reset, so that the reset failure is caused, the next switching process is influenced, 3) the push rod of the elastic claw part is connected with the ratchet wheel in a linkage way through the grooves and the convex blocks embedded into the grooves, and the stability of the connection mode is not enough.
In order to overcome the defects, the inventor particularly develops a shower button switching improved structure capable of being switched smoothly, and the scheme is generated.
