Description

  The present invention relates to the field of bath equipment, and more particularly to a button-switchable showerhead device.

  Conventional handheld showerheads normally switch the water discharge state by rotating a sprinkling plate. However, since it is necessary to apply opposing forces with both hands, the operation is troublesome and cannot be performed with one hand.

  A single-button switching shower head that switches the water discharge state with one button so as to easily switch the water discharge state of the shower head with one hand is commercially available. As shown in FIG. 12, specifically, in the single-button switching shower head, the button 1 ′ is driven to move the push rod 2 ′, and the push block 2 ′ and the push block 2 ′ are attached to the push rod 2 ′. A first spring 4 'is disposed, and the push block 3' drives the ratchet 5 'in the shower head to rotate in one direction, and the ratchet 5' rotates in synchronization with a water basin in the shower. . In use, the button 1 'is pressed to drive the push rod 2' to move, and the push rod 2 'moves the push block 3' in conjunction with the push block 3 'to rotate the ratchet 5'. Drive to move. Thus, the water basin is rotated so that the water diverting holes of the water basin movably communicate with the different water supply holes of the water spouting section, and the switching of the water spouting state is realized. When the button 1 ′ is pressed, the push rod 2 ′ moves in the opposite direction by the action of the first spring 4 ′ to return to the initial position, and the push block 3 ′ moves in the opposite direction in conjunction with the initial movement to move the initial position. Return to position. However, since there is no position regulating means, usually, the button 1 'is driven to move the push block 3', and the ratchet 5 'interlocks with the water basin until the push block 3' separates from the ratchet 5 '. Switching cannot be completed. The feel when pushing in this way is not good.

  Even if the push block 3 'returns to the initial position, the push block 3' is locked so that the push block 3 'can be engaged with the ratchet teeth of the ratchet 5' and rotate the ratchet 5 'in conjunction with the push block 3'. A second spring 6 'is movably disposed on the push rod 2' and provided between the push block 3 'and the push rod 2' so as to always push the push block 3 'against the ratchet 5'. The spring 6 'is arranged to press against the push block 3'. However, since the push block 3 'is always pressed against the ratchet 5' by arranging the second spring 6 ', the push block 3' moves in the process of engaging with the ratchet teeth of the ratchet 5 ', so that the push block 3' is pressed. There is a possibility that the push block 3 'and the ratchet 5' are liable to be worn due to friction between the 'and the ratchet 5', and the shower head switching function may be invalidated, so that the service life is not extended. In addition, the push rod 2 'and the second spring 6' cause the ratchet 5 'to receive two mutually perpendicular pressures from the push block 3' during rotation. The first pressure is the pressure generated by the push block 3 'as the push rod 2' pushes the push block 3 'to move in the forward direction, and the second pressure pushes the second spring 6'. The pressure generated by the push block 3 'when pressed against 3'. The resultant of the two pressures may be along the radial direction of the ratchet 5 ', the push block 3' cannot push the ratchet 5 'to rotate the ratchet 5', and the ratchet 5 'becomes stuck. Would. In this case, unless the force applied to the push rod 2 'is changed, the push block 3' cannot push and rotate the ratchet 5 '. Therefore, the conventional single-button switching shower head has a drawback that switching is not stable in addition to a short service life.
