Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of control valve, and particularly relates to a control valve structure. BACKGROUND

[0002] With the improvement of people's living standards and the rapid development of the home industry, people's demand for home products is getting higher and higher. Now more and more young people want to install a bathtub when they decorate the bathroom at home, which is to meet the current people's demand for high-quality home products. The traditional bathtub is only a cylinder that can hold water, as long as water can be added to meet people's bathing needs. With the development of the bathroom industry, people give the bathtub more functions, and with the rapid rise of the current smart home industry, more and more bath tubs with massage function enter people's life.

[0003] For example, the Chinese utility model patent with the publication number CN221490692U discloses a massage bathtub, which specifically sets a massage nozzle in the bathtub, and pressurizes water from the water pump and sprays it from the massage nozzle, so as to achieve the effect of massaging the human body by high-pressure water flow impacting the human skin. Moreover, the pressurized water flow is from the bathtub, so the massage nozzle always only has the function of spraying water. In fact, negative pressure water flow can have a pulling effect on human skin and also has a good massage effect. At present, in order to achieve such an effect, a water pump is generally used to realize the water flow exchange of each water suction port and water outlet port by forward and reverse rotation. However, the continuous forward and reverse rotation of the water pump is easy to cause damage to the water pump. SUMMARY

[0004] The purpose of the present application is to provide a control valve structure and a bathing basin control method, which solves the problem that the water pump is easy to be damaged by continuously switching the direction of the massage water flow by using the forward and reverse rotation of the water pump in the existing bathing machine.

[0005] To achieve the above-mentioned purpose, the control valve structure provided by the embodiments of the present application is arranged in a bathing basin and used for controlling the direction of water flow. The control valve comprises a shell, a moving block and an electric cylinder. A piston cavity is arranged in the shell, and a first connecting port, a second connecting port, a third connecting port and a fourth connecting port communicating with the piston cavity are arranged on the outer side of the shell. The first connecting port and the second connecting port are respectively connected with the input end and the output end of a pressurizing pump. The third connecting port and the fourth connecting port are respectively connected with a first connecting pipe and a second connecting pipe. The moving block is slidingly arranged in the piston cavity. At least two groups of water flow channels are arranged in the moving block, including a first channel, a second channel, a third channel and a fourth channel. The electric cylinder is connected with the moving block and used for pushing the moving block, so that different water flow channels are connected with the first connecting pipe, the second connecting pipe and the input end and the output end of the pressurizing pump.

[0006] Further, the outer side of the shell is further provided with a fifth interface, and the first water pipe is connected to the fifth interface; the fifth channel and the sixth channel are further arranged in the moving block; and the first water pipe is connected to the water supply system.

[0007] Further, the outer side of the shell is further provided with a sixth interface, and the second water pipe is connected to the sixth interface; the seventh channel and the eighth channel are further arranged in the moving block; and the second water pipe is connected to the drainage system.

[0008] Further, the second connecting pipe is further connected with a switching valve for switching the communication between the first connecting pipe and the second connecting pipe.

[0009] The control valve structure provided by the embodiment of the present application has at least the following technical effects:

[0010] When the water flow direction of the first connecting pipe and the second connecting pipe needs to be switched, the moving block is moved by the electric cylinder, so that the two ends of the first channel are respectively communicated with the first connecting port and the first connecting pipe, and the second channel is communicated with the second connecting port and the second connecting pipe. When the water flow of the first connecting pipe and the second connecting pipe needs to be reversed, the moving block is moved again by the electric cylinder, so that the third channel is respectively communicated with the input end of the pressure pump and the second connecting pipe, and the fourth channel is respectively communicated with the output end of the pressure pump and the first connecting pipe; therefore, the switching of the water flow can be realized by the control valve, without the need of using the forward and reverse rotation of the pressure pump to switch, so that the pressure pump can be protected, and only a one-way pump needs to be used, thereby reducing the cost.

[0020] In one embodiment of the control valve structure of the present application, please refer to Figures 1 to 4; a bathtub for bathing and massaging. Specifically, the bathtub comprises a bathtub body 100, a control valve 200, a pressurized pump 300 and a control system (not shown in the drawings), the bathtub body 100 is provided with a water tank 101, the inside of the bottom side of the bathtub body 100 is provided with a cavity 102, the bottom of the water tank 101 is provided with a plurality of through holes 103, and the through holes 103 penetrate to the cavity 102. Each through hole 103 is provided with a spray head 400, and the bottom end of the spray head 400 is provided with a pipe joint 410. The control valve 200 and the pressurized pump 300 are arranged in the cavity 102, the control valve 200 is provided with at least four connection ports, the input port and the output port of the pressurized pump 300 are connected to two connection ports of the control valve 200, and the other two connection ports of the control valve 200 are respectively provided with a first connecting pipe 500 and a second connecting pipe 600. The pipe joints 410 of a plurality of spray heads 400 are connected to the first connecting pipe 500, and the remaining spray heads 400 are connected to the second connecting pipe 600. The control valve 200 and the pressurized pump 300 are electrically connected to the control system, and the control system is used to control the control valve 200 to switch the water inlet or outlet of the first connecting pipe 500 and the second connecting pipe 600, so as to realize the switching of the water flow direction of the first connecting pipe 500 and the second connecting pipe 600. Specifically, when using the bathtub of the embodiment to bathe and massage, hot water for bathing can be injected into the water tank 101, and the user can lie in the water tank 101 of the bathtub, and the control system controls the pressurized pump 300 to work, so that the pressurized pump 300, the first connecting pipe 500, the second connecting pipe 600 and the water tank 101 form a circulating water flow, so that the water in the water tank 101 is continuously circulated through the pressurized pump 300. When the pressurized pump 300 works, the water in the water tank 101 enters the first connecting pipe 500 from part of the spray heads 400, and then enters the pressurized pump 300, the second connecting pipe 600 in turn, and finally is sprayed from the spray heads 400 connected to the second connecting pipe 600, so as to impact and massage the skin of the human body, and at the same time, the spray heads 400 connected to the first connecting pipe 500 form negative pressure, so as to form the feeling of pulling the skin, thereby forming two different massage effects. By continuously switching the water flow direction of the first connecting pipe 500 and the second connecting pipe 600 through the control valve 200, the water suction or water spraying of the spray heads 400 is continuously switched, and the massage effect on the skin of the human body is continuously switched, thereby meeting the needs of the user. In addition, the control system controls the pressurized pump 300 to continuously or pulse pump water, and at the same time, the control system switches the control valve 200, so that the first connecting pipe 500 and the second connecting pipe 600 are alternately communicated with the input end of the pressurized pump 300. In turn, different massage modes can be switched, and the experience is increased.

[0021] Further, with reference to Figure 4, the control valve 200 is provided with five connection ports, the fifth connection port of the control valve 200 is connected with the second water pipe 700, and the end of the second water pipe 700 extends out of the cavity 102. Specifically, the second water pipe 700 is a drain pipe connected with the drainage system. In this embodiment, the first connection pipe 500 is switched to communicate with the drain pipe 700 by the control valve 200, while the second connection pipe 600 is in a closed state. Therefore, the nozzle 400 connected with the first connection pipe 500 forms a negative pressure by the pressurizing pump 300 to suck the water in the water tank 101 into the pressurizing pump 300, and then discharge from the drain pipe 700, so as to realize the rapid discharge of the water in the water tank 101.

[0022] Further, with reference to Figure 4 , the control valve 200 is further provided with a water inlet connected with the hydrogen-rich water machine. Therefore, the water inlet is switched to form a water path with the pressurizing pump 300 and the second connection pipe 600 by the control valve 200, and then the pressurizing pump 300 pumps the water in the hydrogen-rich water machine into the water tank 101, so as to realize the bathing with the hydrogen-rich water. In addition, the user can first lie in the bathtub, and then the pressurizing pump 300 pressurizes the hydrogen-rich water to be sprayed from the nozzle 400, so as to achieve the massage effect on the human body.

[0023] Further, a specific embodiment of the control valve 200. Specifically, please refer to Figure 4The control valve 200 comprises a housing 210, a moving block 220 and an electric cylinder 230. The housing 210 is internally provided with a piston cavity 211, and the outer side of the housing 210 is provided with a first connecting port 212, a second connecting port 213, a third connecting port 214, a fourth connecting port 215, a fifth connecting port 216 and a sixth connecting port 217 which are in communication with the piston cavity 211. The first connecting port 212 and the second connecting port 213 are respectively connected with the input end and the output end of the pressurizing pump 300; the third connecting port 214 and the fourth connecting port 215 are respectively connected with the first connecting pipe 500 and the second connecting pipe 600. The fifth connecting port 216 is connected with the second water pipe 700, and the sixth connecting port 217 is connected with the first water pipe 800. The moving block 220 is slidingly arranged in the piston cavity 211. The moving block 220 is internally provided with four groups of water flow channels which are constantly switched with the pressurizing pump 300, the second connecting pipe 500 and the second connecting pipe 600. Specifically, the four groups of water flow channels comprise a first channel 221, a second channel 222, a third channel 223, a fourth channel 224, a fifth channel 225, a sixth channel 226, a seventh channel 227 and an eighth channel 228. Specifically, the first channel 221 and the second channel 222 form a first group of water flow channels; the third channel 223 and the fourth channel 224 form a second group of water flow channels. The fourth channel 224 and the fifth channel 225 form a third group of water flow channels; the seventh channel 227 and the eighth channel 228 form a fourth group of water flow channels. The electric cylinder 230 is connected with the moving block 220 and is used to push the moving block 200 so that different water flow channels are in communication with the first connecting pipe 500, the second connecting pipe 600 and the input end and the output end of the pressurizing pump 300.

[0024] Specifically, when the first connecting pipe 500 is connected with the input end of the pressurizing pump 300 and the second connecting pipe 600 is connected with the output end of the pressurizing pump 300, the moving block 220 is pushed by the electric cylinder 230 to move so that the two ends of the first channel 221 are respectively in communication with the first connecting port 212 and the first connecting pipe 500, and the second channel 222 is in communication with the second connecting port 213 and the second connecting pipe 600.

[0025] When the water flow of the first connecting pipe 500 and the second connecting pipe 600 needs to be reversed, the moving block 220 is driven by the electric cylinder 230 to move again so that the third channel 223 is respectively in communication with the input end of the pressurizing pump 300 and the second connecting pipe 600, and the fourth channel 224 is respectively in communication with the output end of the pressurizing pump 300 and the first connecting pipe 500.

[0026] When the water flow direction of the first connecting pipe 500 and the second connecting pipe 600 needs to be switched, the moving block 220 is pushed to move by the electric cylinder 230, so that the two ends of the first channel 221 are in communication with the first connecting port 212 and the first connecting pipe 500 respectively, and the second channel 222 is in communication with the second connecting port 213 and the second connecting pipe 600. When the water flow of the first connecting pipe 500 and the second connecting pipe 600 needs to be reversed, the moving block 220 is driven to move again by the electric cylinder 230, so that the third channel 223 is in communication with the input end of the pressure pump 300 and the second connecting pipe 600 respectively, and the fourth channel 224 is in communication with the output end of the pressure pump 300 and the first connecting pipe 500 respectively; thus the switching of the water flow can be realized by controlling the valve, without using the forward and reverse rotation of the pressure pump for switching, so as to protect the pressure pump, and only a one-way pump needs to be used, thereby reducing the cost.

[0027] When water needs to be added to the sink 101, the moving block 220 is pushed to move by the electric cylinder 230, so that the fifth channel 225 is in communication with the sixth connecting port 217 and the first connecting port 212, and the sixth channel 226 is in communication with the second connecting port 213 and the second connecting pipe 600. Thus, the water of the first water pipe 800 enters the fifth channel 225 and then enters the first connecting port 212, is pressurized by the pressure pump 300, and is output from the sixth channel 226 into the second connecting pipe 600, thereby adding water to the sink.

[0028] When water needs to be drained, the moving block 220 is pushed to move by the electric cylinder 230, so that the seventh channel 227 is in communication with the third port 214 and the first port 212, and the eighth channel 228 is in communication with the fifth port 216 and the second port 213. Thus, the first connecting pipe 500, the seventh channel 227, the pressure pump 300, the eighth channel 228 and the drain pipe 700 form a water circuit, so that the water in the sink 101 can be drained by the pressure pump 300.

[0029] Further, please refer to Figure 4 , the first connecting pipe 500 and the second connecting pipe 600 are further connected with a switching valve 900 for switching the communication between the first connecting pipe 500 and the second connecting pipe 600. In this embodiment, the first connecting pipe 500 and the second connecting pipe 600 can be made to communicate by the switching valve 900; thus when water is added to the sink 101 or drained, the first connecting pipe 500 and the second connecting pipe 600 can work at the same time to improve the efficiency. And the first water pipe 800 can be used to add water to the first connecting pipe 500 and the second connecting pipe 600 at the same time, so as to clean the first connecting pipe 500 and the second connecting pipe 600 with clean water. When water is drained, the water in the sink 101 can be used to flush the remaining channels in the control valve 200, so as to avoid the problem of breeding of bacteria in the control valve 200, the first connecting pipe 500 and the second connecting pipe 600.

[0030] Further, the edge of the through hole 103 is inwardly recessed downward to form a recessed cavity, and the spray head 400 is arranged in the recessed cavity. Thus, the spray head 400 does not protrude from the upper surface of the water tank 101.

[0031] Further, the spray head 400 is a spherical spray head, and the position of the water outlet can be adjusted.

[0032] Further, the spray head 400 includes a seat body 420 and a spherical spray head 430. The seat body 420 is provided with a through hole, and the seat body 420 is provided with a spherical cavity. The spherical spray head 430 is rollingly arranged in the spherical cavity. The seat body 420 is provided with a water passing hole in communication with the spherical spray head 430.

[0033] The above merely describes the preferred embodiments of the present application, but should not be used to limit the present application. Any modification, equivalent replacement, and improvement within the spirit and principle of the present application should be included in the protection scope of the present application.
