It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
[0022] Some embodiments of the present invention are described below in conjunction with the accompanying drawings. Embodiment 1:
[0023] Combination Figure 1-3 As shown, this embodiment provides a push faucet, including: a main body module 100 and a filter module 200.
[0024] Among them, the main body module 100 includes a main pipe 110, a water outlet pipe 120 installed on one side of the main pipe 110 and connected to the main pipe 110, a water outlet nozzle 130 installed on the water outlet pipe 120, an annular seat 140 fixed on the inner wall of the main pipe 110, a valve core 150 movably arranged in the inner cavity of the main pipe 110, a first spring 160 connecting the bottom end of the valve core 150 and the annular seat 140, a pressing piece 170 movably sleeved on the top end of the main pipe 110 and extending into the inner cavity of the main pipe 110 and fixedly connected to the valve core 150, an annular bottom plate 180 fixed on the inner wall of the main pipe 110, and a movable part 190 arranged through the annular bottom plate 180.
[0025] The main pipe 110 is used to install other components and is also used to connect with the water pipe to facilitate the delivery of water. The water outlet pipe 120 is used to install the water outlet nozzle 130, and the water outlet nozzle 130 is used to deliver water.
[0026] The annular seat 140 is used to install the first spring 160 to maintain the stability of the first spring 160. The valve core 150 is movably arranged, and a right-angle flow channel 151 is opened in the inner cavity of the valve core 150. When the valve core 150 moves downward, the right-angle flow channel 151 is connected with the water outlet pipe 120, and water enters the water outlet pipe 120 through the main pipe 110 and is sent out. When the valve core 150 moves upward, one end of the right-angle flow channel 151 is blocked by the inner wall of the main pipe 110, and the water flow cannot enter the water outlet pipe 120, that is, the faucet is closed. The first spring 160 is used to drive the valve core 150 to reset after the valve core 150 moves downward.
[0027] The pressing member 170 is used to drive the valve core 150 to move downward, and includes a pressing cap 171 sleeved on the top end of the main pipe 110 and a support rod 172 with one end fixed on the inner top wall of the pressing cap 171 and the other end extending into the main pipe 110 and fixedly connected with the valve core 150. The pressing cap 171 is used to facilitate the user to press it, and at the same time forms a sealed space between the top end of the main pipe 110, and the support rod 172 is used to connect the pressing cap 171 and the valve core 150 to form a whole, so that when the pressing cap 171 moves downward, it drives the valve core 150 to move downward synchronously.
[0028] The top of the main pipeline 110 is symmetrically provided with through holes 111, and the annular bottom plate 180 is fixed on the inner wall of the through hole 111. When the pressure cap 171 is pressed and moved downward, the air between the pressure cap 171 and the top of the main pipeline 110 is pressed into the inner cavity of the main pipeline 110 through the through hole 111. The movable member 190 includes a circular plate 191 arranged at the bottom end of the annular bottom plate 180, a round rod 192 fixed in an annular array at the top of the circular plate 191 and passing through the annular bottom plate 180, an annular top plate 193 fixed at the top of the round rod 192, and a second spring 194 sleeved on the round rod 192. An air hole 1911 is opened in the middle of the circular plate 191. When air enters the through hole 111 from the pressure cap 171, the circular plate 191 is driven to extend outward into the main pipeline 110 under the action of air pressure. At this time, the pressure The air in the cap 171 enters the main pipeline 110 through the through hole 111. The round rod 192 is used to install the annular top plate 193 and limit the movement of the circular plate 191. One end of the second spring 194 is fixed on the annular top plate 193, and the other end is fixed on the annular bottom plate 180. It is used to drive the top plate to move upward, and the circular plate 191 is driven to reset and adhere to the annular bottom plate 180 through the round rod 192. In addition, an air hole 1911 is opened in the middle of the circular plate 191, so that when air enters the pressure cap 171 from the main pipeline 110, it can only enter the pressure cap 171 through the air hole 1911 on the round hole, thereby slowing down the gas discharge speed in the main pipeline 110, and buffering and decelerating the reset of the valve core 150 through the air pressure, thereby extending the reset speed of the valve core 150, that is, realizing the delay of water outlet.
[0029] The filter module 200 is used to filter the water entering the main pipe 110, and includes a shell 210 installed in the inner cavity of the main pipe 110 through a threaded connection, a first filter screen 220 fixed on the inner wall of the shell 210, a second filter screen 230 fixed at one end of the shell 210, nano anti-scaling metal ceramic pellets 240 filled in the inner cavity of the shell 210 and located between the first filter screen 220 and the second filter screen 230, and an arc plate 250 fixed on the end of the shell 210.
[0030] An internal thread is provided on the inner wall of the main pipe 110, and an external thread is provided on the outer surface of the shell 210, and the external thread and the internal thread are meshed with each other, so as to facilitate the installation and disassembly of the shell 210. The first filter screen 220 is used to filter larger impurities in the water, and at the same time cooperates with the second filter screen 230 to limit the nano anti-scaling metal ceramic pellets 240 to prevent the nano anti-scaling metal ceramic pellets 240 from flowing out of the shell 210.
[0031] Due to the microporous structure and surface charge characteristics of the nano anti-scaling metal ceramic pellets 240, when water enters the nano anti-scaling metal ceramic pellets 240, tiny particles such as suspended matter, bacteria and viruses in the water will be captured by the micropores on the surface of the nano anti-scaling metal ceramic pellets 240, and then the suspended matter, microorganisms and organic matter in the water will be filtered and removed, avoiding their adhesion to the inner wall of the valve core 150 to form scale, thereby ensuring the cleanliness of the valve core 150.
[0032] The arc plate 250 is used to facilitate the screwing of the housing 210 , thereby increasing the convenience of installing and disassembling the housing 210 .
[0033] The working principle and use process of the utility model are as follows: when in use, the pressure cap 171 is pressed down, and the valve core 150 is driven to move downward through the support rod 172, so that the right-angle flow channel 151 on the valve core 150 is connected with the water outlet pipe 120. At this time, the water flows into the main pipe 110 through the bottom end of the main pipe 110. When entering the main pipe 110, the first filter screen 220 can filter larger impurities in the water, and when the water flows through the nano-scale-proof metal ceramic pellets 240, the suspended matter, bacteria, viruses and other tiny particles in the water will be captured by the micropores on the surface of the nano-scale-proof metal ceramic pellets 240, and then the suspended matter, microorganisms and organic matter in the water are filtered and removed, avoiding their adhesion to the inner wall of the valve core 150 to form scale, and then the water entering the main pipe 110 enters the water outlet pipe 120 through the right-angle flow channel 151 of the valve core 150, and enters the water outlet pipe 120 from the water outlet pipe 120 to the water outlet nozzle 130 for delivery. When the pressure cap 171 moves downward, the air between the pressure cap 171 and the top of the main pipeline 110 is pressed into the inner cavity of the main pipeline 110 through the through hole 111. When the gas enters the through hole 111 from the pressing member 170, the circular plate 191 is driven to extend into the main pipeline 110 under the action of air pressure. At this time, the air in the pressure cap 171 enters the main pipeline 110 through the through hole 111. When the user releases the pressure cap 171, the first spring 160 releases its elastic force to drive the valve core 150 to reset. The valve core 150 compresses the air in the main pipeline 110 during the resetting process. At the same time, the circular plate 191 is driven by the second spring 194 to be close to the annular bottom plate 180, so that the air in the main pipeline 110 can only enter the pressure cap 171 through the air hole 1911 on the circular hole, slowing down the gas discharge speed in the main pipeline 110, buffering and decelerating the resetting of the valve core 150 through air pressure, and extending the resetting speed of the valve core 150, that is, realizing the delay of water discharge.
[0034] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
