Detailed Description

The invention is further described with reference to the following figures and examples.

As shown in fig. 1 and 7, the valve-controlled faucet of the present invention comprises: a stainless steel shell 203, a mounting support 204, a mounting locking nut 205, a button 202, a water outlet pipe 201 and the like. Source water is connected from the lower end S of the mounting support 204 and flows out from a water outlet K at the upper end of the water outlet pipe 201.

As shown in fig. 2 and 3, the valve-controlled faucet of the present invention comprises several large components, such as a stainless steel housing 203, a mounting base 204, a button 202, a water outlet pipe 201, a valve body 312, etc. In the stainless steel shell 203, the upper part of the mounting support 204 is connected with a valve body 312 in a sealing fit manner, the side surface of the valve body 312 is connected with a valve cover 315, the outer side of the valve cover 315 is connected with a ratchet wheel control mechanism, and the upper part of the valve body 312 is connected with a water outlet pipe 201. The middle part of the valve body 312 is provided with a water outlet cavity 105, and the lower part is provided with a water inlet cavity 108. The valve body 312 is provided with a sealing surface 109 on the inner side of the middle part, a diaphragm 313 is arranged on the sealing surface 109, a reinforcing plate 314 is matched behind the diaphragm 313, and the diaphragm 313 is supported by the reinforcing plate 314. When the valve is in a closed state, the diaphragm 313 is tightly attached to the sealing surface 109 of the valve body 312, and the sealing effect is ensured.

The valve body 312, together with the diaphragm 313 and the bonnet 315, form three chambers, the inlet chamber 108, the outlet chamber 105 and the control chamber 104. The inlet chamber 108 is in communication with the control chamber 104 through the aperture 107 in the upper portion of the valve body 312. The control chamber 104 and the water outlet chamber 105 are communicated with the water outlet chamber 105 through the control sealing surface 102 and the small hole 101 and the small hole 106 at the bottom.

A small control plug 305 is provided at the lower end of the orifice 101. The small plug 305 is driven by a ring magnet 307 sleeved outside the gland 315. The ring magnet 307 is embedded in the slider 306. The slider 306 and the transition block 303 are riveted together by a rivet 304. The lower part of the sliding block 306 is supported by a return spring 309, and the upper part is controlled by an axial ratchet mechanism which is composed of the button 202, the lower rotary disc 301 and the sleeve 302. The sleeve 302 is fixed with the stainless steel housing 203. The inner side of the sleeve 302 is provided with axial guide grooves which are uniformly distributed in the circumferential direction, and the adjacent guide grooves are provided with thrust blocks at intervals. The axial end faces of both the button 202 and the lower dial 301 are a pair of axial ratchet mechanisms. When the button 202 is pressed, the button 202 and the lower dial 301 slide together downward along the axial guide groove inside the guide groove 302 and remain free from relative rotation. The axial guide slots in the sleeve 302 are designed such that a set of axial guide slots are evenly distributed along the circumference for the button 202 to slide axially in the sleeve 302 without relative rotation. The sleeve 302 and the housing 203 are fixed, and when the button 203 slides up and down in the sleeve 302, the ratchet of the lower dial 301 engages with the driving cam at the lower end of the button 202. The lower rotary disc 301 is engaged with the axial guide groove in the sleeve 302 in a half-engaged state. That is, in the upper half of the stroke, the lower dial 301 and the button 202 are constrained by the guide slots in the sleeve 302, and only slide axially but cannot rotate. When button 202 and lower dial 303 are moved to the second half of the stroke of sleeve 302, button 202 is still constrained by the guide slot in sleeve 302 and cannot rotate, and lower dial 301 is disengaged from the guide slot in sleeve 302, and at this time, lower dial 301 can rotate by a small angle under the action of the ratchet set and rebound upwards along sleeve 302 under the action of return spring 309. Because the guide slots within sleeve 302 provide axial stops for spaced slots, this allows the position of lower turntable 301 within sleeve 302 to be at one of the "up" and "down" dead center positions. Thus, when the button 202 is continuously pushed, the lower dial 301 is at one of the upper and lower dead point positions.

In summary, referring to fig. 2, when the button 202 is pressed, the lower dial 301 is operated by the ratchet mechanism to be in the bottom dead center position. At this time, the slider 306 drives the ring magnet 307 to be at the bottom dead center position, the armature 305 is pushed to the top dead center by the sealing spring 308, the channel communicating the control chamber 104 and the water outlet chamber 105 is closed at the sealing surface 102, the channel 101 is closed, at this time, the control chamber 104 is at a high pressure due to the communication with the water inlet chamber 108, the diaphragm 313 is compacted on the sealing surface of the valve body 312, and the valve is in a closed state.

As shown in fig. 3, when the button 202 is pressed once again, the button 202, the lower dial 301, and the slider 306 and the magnet 307 are all pushed to the top dead center position by the return spring 309 under the operation of the ratchet mechanism. At this point, the ring magnet 307 drives the armature 305 down to the bottom dead center position. The sealing surface 102 is now clear. The channels 101 and 106 connecting the control chamber 104 and the outlet chamber 105 are open, and the control chamber 104 is vented. The small hole 107 connecting the control chamber 104 and the inlet chamber 108 has a small diameter, and the pressure loss of the fluid is large, so that the control chamber 104 is in a low pressure state. The pressure difference is formed between both sides of the diaphragm 313 to be in a floating state, and the valve sealing surface 109 is opened, and the valve is in an open state.

FIG. 4 is a schematic view of an axial ratchet mechanism. The sleeve 302 is fixed to the housing 203. The button 202 slides up and down along the guide slot within the sleeve 302 when pressed. The lower turntable 301 is driven by the button 202 to slide up and down in the sleeve 302 along the guide slot in the sleeve 302, and when the lower turntable is out of the range of the guide slot, the lower turntable rotates at an angle along the direction of the ratchet wheel to align with the next guide slot.

As shown in fig. 5 and 6, to expand the application range of the present invention, the sealing surface of the valve body and the attached diaphragm may be designed to be circular or elliptical.

Fig. 7 is a three-dimensional exploded view of the faucet. The specific embodiments described above should not be construed as limiting the scope of the invention. Any alternative modifications or alterations to the practice of this invention which would occur to those skilled in the art are intended to be within the scope of the invention. The invention is not described in detail, but is well known to those skilled in the art.
