Abstract
Description
Technical Field
[0001] This utility model relates to an automatic shower machine, and more particularly to the water system of the automatic shower machine, belonging to the field of electromechanical technology. Background Technology
[0002] Automatic shower machines can effectively reduce the physical labor of caregivers and improve the quality of life and hygiene for the elderly or people with mobility difficulties. With the increasing aging population, the market demand for automatic shower machines is also increasing. Automatic shower machines realize functions such as rinsing, bathing and disinfection through water system. Stable and easy-to-control water system is the core of the design and manufacturing of automatic shower machines. Chinese patents also disclose related technical solutions for water systems. For example, Chinese patent application number 2019107163163 discloses a fully automatic shower machine. Its hot water uses a water heater and achieves hot and cold water mixing through a mixing valve. This water supply method makes it difficult to control the water temperature and the control is delayed. In this solution, shower gel and potassium permanganate are both drawn in through the suction port of an ejector (similar to a Venturi tube). As the bath water enters, this method has obvious defects. First, the amount of shower gel and potassium permanganate drawn in is directly related to the flow rate of the ejector liquid. The amount of shower gel and potassium permanganate drawn in cannot be controlled independently. Second, in this solution, the shower gel enters the bath water directly and there is no foaming function. However, the foaming function has a positive effect on the bather and the bathing process. Summary of the Invention
[0003] The purpose of this invention is to overcome the aforementioned problems existing in current automatic shower machines and to provide an automatic shower machine water system.
[0004] To achieve the purpose of this utility model, the following technical solution is adopted: an automatic shower machine water circuit system, including cold water inlet and hot water inlet, which are respectively connected to two inlets of a thermostatic component. The outlet of the thermostatic component is connected to a booster pump, and the outlet of the booster pump is connected to a distribution tank. The distribution tank has multiple outlets, of which outlet A is connected to the shower head through an angle valve, outlet B is connected to the upper shower head through a first electric valve, outlet C is connected to the lower shower head through a second electric valve, and outlet D is connected to the jet interface of an ejector through a third electric valve. A solvent suction pipe is connected to the suction port of the ejector, and a solvent nozzle is connected to the outlet of the ejector. The outlets of peristaltic pumps A and B are connected in parallel to the solvent suction pipe. The inlet of peristaltic pump A is connected to liquid bottle A through a pipe, and the inlet of peristaltic pump B is connected to liquid bottle B through a pipe.
[0005] Furthermore, there is also an outlet E on the water distribution tank, and the fourth electric valve of outlet E is connected to the drainage system.
[0006] Furthermore, the water system is also connected to a compressed air system, which includes an air compressor with two outlets equipped with one-way valves. One outlet is connected to a thermostatic component, and the other outlet is connected to an interface on an ejector.
[0007] Furthermore, an ozone generator is also connected to the water system.
[0008] The positive and beneficial technical effects of this utility model are as follows: The water system adopts a constant temperature component for water supply, which ensures stable water supply and convenient temperature adjustment. A peristaltic pump is used to pump solvent (such as bath liquid or potassium permanganate) into the pipeline. The amount of solvent is very easy to control, and the amount of solvent pumped in is not affected by the flow rate or flow of the fluid sprayed by the ejector. It is not related to the water spray during bathing and can be adjusted flexibly and independently. The compressed air system can dry the system pipeline and generate foam to promote bath liquid during bathing. An ozone generator can be connected to the pipeline system for disinfection. Attached Figure Description
[0009] Figure 1 This is a schematic diagram of the system. Detailed Implementation
[0010] To more fully explain the implementation of this utility model, implementation examples are provided. These implementation examples are merely illustrative of this utility model and do not limit its scope.
[0011] The present invention will be further explained in detail with reference to the accompanying drawings, in which the following references are made: 1: thermostatic component; 2: booster pump; 3: water tank; 4: angle valve; 5: shower head; 6: upper shower head; 7: jet injector; 8: solvent nozzle; 9: peristaltic pump A; 10: peristaltic pump B; 11: liquid bottle A; 12: liquid bottle B; 13: air compressor; 14: lower shower head; 15: ozone generator; 16: one-way valve; 17: drainage system; 18: solvent suction pipeline.
[0012] As shown in the attached diagram, an automatic shower machine water system includes a cold water inlet and a hot water inlet. The cold water inlet and hot water inlet are respectively connected to two inlets of a thermostatic component 1. The outlet of the thermostatic component 1 is connected to a booster pump 2. The outlet of the booster pump 2 is connected to a water distribution tank 3. The water distribution tank has multiple outlets, where outlet A is connected to a shower head 5 via an angle valve 4, outlet B is connected to an upper shower head 6 via a first electric valve, outlet C is connected to a lower shower head 14 via a second electric valve, and outlet D is connected to the jet interface of an ejector 7 via a third electric valve. The suction inlet (i.e., the negative pressure port of the ejector, where negative pressure refers to pressure below atmospheric pressure) is connected to a solvent suction pipe 18, and the outlet of the ejector is connected to a solvent nozzle 8. The solvent nozzle mixes the liquid pumped in by the peristaltic pump and the water flowing out of the outlet D and then sprays it out. The outlets of peristaltic pumps A and B are connected in parallel to the solvent suction pipe 18. The inlet of peristaltic pump A9 is connected to liquid bottle A 11 through a pipe, and the inlet of peristaltic pump B10 is connected to liquid bottle B 12 through a pipe. Liquid bottles A and B are usually bath liquid and potassium permanganate liquid, but other liquids can be used as needed. There is also an outlet E on the water distribution tank. The outlet E channel is connected to the fourth electric valve to the drainage system. The drainage system is lower than the outlet E, and the outlet E is used for drainage.
[0013] The water system is also connected to a compressed air system, which includes an air compressor with two outlets equipped with one-way valves. One outlet is connected to a thermostat, and the other outlet is connected to an interface on an ejector. The compressed air connected to the thermostat is used to dry the water system, and the air connected to the ejector is used to promote the foaming of the bath liquid and increase the foam during bathing.
[0014] The water system also includes an ozone generator 15. To prevent water from entering the ozone generator, a one-way valve 16 is installed after it. The ozone generator's exhaust can be connected to a water distribution tank, a pipe or component connected to the water distribution tank, or even to the inlet of an ejector. The ozone can then enter the water distribution tank through the ejector and the third electric valve. The ozone generator can disinfect the piping system.
[0015] The thermostatic component in this utility model is an existing product. It has three water inlets: one for cold water, one for hot water, and one for water outlet. After setting the temperature, water at the set temperature can flow directly out of the outlet. The product can be from Foshan Sanjun Electronics Co., Ltd.
[0016] The ejector used in this application is an existing commodity, such as the Lige 58615 ejector, which has a gas interface and can be used for gas-liquid mixing.
[0017] In this piping system, water at the set temperature flows from the thermostat into the distribution tank. By controlling the valves on each route, water can flow out separately or simultaneously through the shower head, upper shower head, and lower shower head. When shower gel or potassium permanganate is needed, the third electric valve is activated, and the solvent is pumped into the solvent suction pipeline by the peristaltic pump, from which it can be sprayed out from the solvent nozzle. When more foam is needed, gas is input into the air compressor ejector.
[0018] In this invention, control valves can be added to the pipeline as needed, and a temperature sensor can be installed in the water distribution tank to provide temperature feedback. After showering, the water in the water distribution tank can be drained through outlet E, and then compressed air connected to the thermostat component is used to dry the water in the system to prevent bacterial growth.
[0019] After a detailed description of the embodiments of this utility model, those skilled in the art will clearly understand that various changes and modifications can be made without departing from the scope and spirit of the above-mentioned patent applications. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the scope of the technical solution of this utility model, and this utility model is not limited to the embodiments of the examples given in the specification.
