Abstract: A device integrated hot and cold tap water and hot and cold purified water including a casing pipe, a water guide mechanism, a touch switch, a microcontroller, a pulling head, and first and second magnetic components is provided. The water guide mechanism includes first and second pipelines disposed in the casing pipe. The first and second pipe lines are respectively provided with a first valve body and a touch control assembly. The touch switch and the microcontroller are electrically connected with the touch control assembly. The pulling head includes a fixed cylinder provided in a water outlet of the casing pipe and a bubble former fixed in the fixed cylinder. An interior of the bubble former has an inner waterway and an outer waterway. The first and second pipelines communicate with the water outlet of the casing pipe through the outer waterway and one end of the inner waterway, respectively.

Abstract: The invention discloses a fluid sensing device provided in a flow path through which fluid flows, including a base fixed in the flow path; a piston core rod disposed in the base and connected to the base through an elastic member, the piston core rod being provided with a pushing surface pushed by the fluid in the flow path; a magnet provided on the piston core rod; a magnetic sensing device provided on a side surface of the piston core rod to sense change of magnetic line received as change of position of the magnet, thereby determining whether fluid flows in flow path; wherein the elastic member is disposed such that direction of the restoring force thereof is opposite to the direction of fluid flow in flow path. The present invention has fewer parts and easy production, and can reduce judgement difference caused by low flow rate.

Abstract: The invention discloses a device integrated hot and cold tap and purified water, including: casing pipe providing with first and second pipeline respectively provided with first and second valve body; first pipeline comprising: first water inlet hose having both end communicated with cold water supply part of tap water and water inlet end of first valve body; second water inlet hose having both end communicated with hot water supply part of tap water and water inlet end of first valve body; connecting pipe having both end communicated with water outlet end of first valve body and outer waterway; one end of second pipeline provided with two branch pipes communicated with hot and cold water supply part of purified water, and the other end communicating with inner waterway. The invention has advantages that only one mounting hole is used to integrate hot and cold tap and purified water on a faucet.

Abstract: The disclosure provides a mechanical press-type switch valve core, which subverts usage of traditional switch valve core in control of water, switches from rotary switch to press-type switch, and reduces damage of switch handle during use. You can use other parts of body to press the switch (such as arms) when hands are inconvenient in use process. The appearance is relatively simple and generous in the use of the product. The mechanical press-type switch valve core is provided a compression spring between the pressing assembly and the blocking assembly for up-and-down movement acting on the water-blocked rod, and at the same time overcoming water pressure force of the water-blocked rod and O-shape sealing ring when the valve core is opened. The mechanical press-type switch valve core is sealed with the O-shape sealing ring, which is a static seal, and has high sealing life.

Abstract: A towel rack with multiple usage modes, comprising: first connecting rod; second connecting rod; pair of large skeletons, first upper rod of left side large skeleton and right side large skeleton connecting to first connecting rod by first, second rotation positioning member, respectively, pair of large skeletons and first connecting rod being in relative rotation state or locked state when pressing or releasing first button; pair of small skeletons, second upper rod of left side small skeleton connecting to first lower rod of left side large skeleton, and second upper rod of right side small skeleton connecting to first lower rod of right side large skeleton through third and fourth rotation positioning member, respectively, pair of small skeletons and large skeletons being in relative rotation state when pressing second button.
