Description

Technical Field

[0001] The present application belongs to the technical field of health care equipment, and in particular, relates to a physical bathing skin care equipment. Background Art

[0002] Chemical active agent washing and care products generate a lot of air, soil and water pollution during production and use. The current situation is that the impact of chemical active agents on the environment and residual damage can only be reduced but not eliminated. Physical bathing and skin care methods that remove both grease and dandruff and are environmentally friendly and pollution-free are the ultimate goal of human beings. According to the calculation that 1 billion people in the world use 8 liters of water for each shampoo, 8 million tons of chemically polluted tail water is directly generated every day for shampooing alone. Among them, nearly half of the non-urban population has doubled the amount of water bodies polluted by shampoo. The water temperature for shampooing is usually around 40 degrees. According to the average natural water temperature of 20 degrees, the energy efficiency is set at 60%, and the calorific value of natural gas is determined as: 3.5×10^4KJ / m3, and a single shampoo consumes 8 liters*3.36×10^5 joules / (60%×3.5×10^7)*0.2=8*0.016*0.2=0.0256 cubic meters Every 1 billion times of shampooing consumes 25.6 million cubic meters of natural gas, consumes 15 times the volume of oxygen in the air, and generates the same volume of carbon dioxide. During the washing process, allergens, chemical damage from non-ionic surfactants and anionic surfactants, and damage and infection from hard objects such as nail scratches have always been unavoidable. Residual damage cannot be avoided. Chemical surfactants cannot directly remove solid dandruff and fat globules at the roots of hair. Therefore, it is necessary to provide a device that can wash sebum without water temperature requirements, and it is necessary to provide a long-lasting, efficient, durable, environmentally friendly skin and hair washing and health care equipment without chemical residues.

[0003] Special groups of people who engage in ocean voyages, long-distance transportation, scattered living, or have limited limb movement urgently need to provide a washing and care equipment that does not require scratching or rubbing and does not contain any chemical residues in order to take care of themselves.

[0004] Itch has accompanied humans for millions of years. The most basic method to deal with skin itching caused by various factors is scratching and pressing. The scratching and pressing method is not suitable for all people and different parts of the body and is more likely to cause secondary injuries. The more you scratch, the more itchy it becomes, and the more itchy you scratch, the more you scratch. It is necessary to provide a skin health care device that can effectively reduce swelling and itching without scratching to improve the quality of human life.

[0005] It is difficult to avoid secondary damage to hair and skin caused by hair dye products. The production and use of hair dye products generate a large amount of air pollution and water pollution, which has a certain impact on the health of those who come into contact with them. There is a need for a simple and efficient rehabilitation training device to assist superficial skin. It can improve the body fluid environment of hair roots and human nerve endings through physical methods, restore the body fluid environment of hair follicles, and restore their original functions.

[0006] In the field of hair loss rehabilitation, there are currently two types: drug methods and physical methods such as LLLT, friction, and liquid nitrogen cold stimulation. The side effects of drug rehabilitation are worrying, the existing physical rubbing efficiency is low, and liquid nitrogen cold stimulation will cause certain pain or edema. The remedy is artificial hair transplantation, which can only reduce but not increase the total amount of hair. A simple and efficient device is needed to assist in reconstructing the superficial skin cell environment through the principle of body fluid energy transfer to promote hair regeneration.

[0007] Solid object reciprocating massage device is a common tool for people to relax and maintain health. The inherent shape of the striking object limits the effective use of different parts, and it cannot cover all parts of the body surface. The effect of solid object massage and relaxing joints is not ideal. It is necessary to provide a health care device that can relieve fatigue by transmitting energy with a liquid medium. Summary of the invention

[0008] The purpose of this application is to provide a physical bathing skin health care device.

[0009] In order to achieve the purpose of this application, the following technical solutions are provided: A physical bathing skin care equipment comprises: a cavitation shower head, a plunger pump, and a fluid pipe, wherein the water outlet end of the fluid pipe is sealedly connected to the cavitation shower head, and the water inlet end of the fluid pipe is sealedly connected to the plunger pump.

[0010] Further: a cavitation shower head comprises: a water outlet plate, a mixed flow baffle, a main body, and a handle; the water outlet plate is provided with a plurality of fixed water outlet holes or a plurality of split assembled water outlet holes, the physical property of the material of the water outlet hole is rigidity, the shape of the water outlet hole is a conical countersunk head, the water outlet hole comprises a countersunk head end and a necked end, the aperture range of the necked end is 0.39-1.1MM, the hole depth of the necked end is not greater than the aperture, and the countersunk head end is arranged in the direction of water flow, which can reduce the water head loss, and create cavitation and air explosion conditions for the pulse water when passing through the water outlet hole, so that the single pulse kinetic energy can remove fat and the single pulse energy can propagate to a certain depth under the skin, thereby recreating the scope of action. The mixed flow baffle is provided with a mixed flow hole, and the water flows through the outlet hole and the mixed flow hole in turn and is ejected at a high speed. The diameter of the mixed flow hole is larger than the diameter of the water outlet hole. The mixed flow hole provides space for secondary mixing of water and air. The main body is provided with a high-pressure water chamber to further reduce the water flow speed at the water inlet end of the water outlet hole and adjust the balanced water outlet of each water outlet hole. The water outlet plate is sealed and installed at the water outlet of the high-pressure water chamber, and the water inlet of the high-pressure water chamber is sealed and connected with the fluid pipe. The handle is fixedly connected to the main body or integrated with the main structure as a whole, which is convenient for holding and expanding the water outlet coverage.

[0011] Furthermore: the main material of the fluid pipe wall is made of semi-hard material to reduce pressure loss, with a Shore D hardness of about 50-65 ShoreD, is bendable, has small deformation, low energy storage, and an elastic modulus of about 500-800MPa at room temperature.

[0012] Furthermore: the high-pressure chamber enclosure and chamber sealing components of the plunger pump are made of low-energy storage materials to ensure the peak and valley amplitude difference of the pulse water flow velocity of the cavitation shower outlet. According to the Bernoulli equation, the minimum flow velocity of water flow that undergoes cavitation at one atmosphere of pressure at normal temperature is about 14 meters per second. In actual applications, the selection of a single pulse flow rate can be combined with the working efficiency of the plunger pump and the water output per unit time to calculate the approximate range to ensure that all or part of the pulse water flow at the outlet exceeds 20 meters per second.
