Description

An Electric Heating Fluidized Massage Sand Therapy Bed

technical field

The invention relates to an auxiliary medical treatment device, in particular to an electric heating fluidized massage sand therapy bed.

Background technique

Due to the acceleration of the pace of life, great changes have taken place in the way of life and work of modern people. Sitting in an air-conditioned environment for a long time, coupled with lack of exercise, lack of perspiration and detoxification, leads to a sub-healthy state of the human body. In the long run, it can lead to many diseases. The heated sand will emit infrared rays, which have basically the same wavelength as the infrared rays emitted by the body, which is called "life light wave" in medicine. Far-infrared rays can improve and prevent various diseases caused by blood circulation and microcirculation disorders. After the "life light wave" penetrates into the body, it will increase the temperature of the deep subcutaneous layer, expand the microvessels, accelerate blood circulation, help remove the accumulation of blood vessels and harmful substances in the body, and remove obstacles that hinder metabolism (such as harmful substances in food, fats, etc.) and subcutaneous fat, sodium ions, uric acid, cosmetic residues accumulated in pores, etc.), rejuvenate tissues, promote enzyme production, activate tissue cells, prevent aging, and strengthen the immune system. Coupled with the effect of the weight of the sand itself on the human body, it can speed up metabolism and improve sub-health.

At present, only the natural sand fields in Turpan can be used for sand therapy in the whole country. Due to geographical limitations, natural sand therapy cannot be promoted nationwide. Moreover, under the action of sunlight in the natural sand field, the surface temperature of the sand is very high, and the temperature below the surface is relatively low. During sand therapy, sand layers need to be mixed artificially, but the uneven temperature of the sand layer seriously affects the effect of sand therapy.

Although the existing electric heating sand therapy bed can artificially heat the sand, due to the slow heat transfer of the sand layer and the non-fluidity of the sand layer without external force, most of the existing electric heating sand therapy beds still have uneven sand temperature and power consumption. A large amount of problems, the user experience is poor. Although there is a fluidized sand therapy bed under the action of mechanical external force, the structure is complex and the cost is high, so it is difficult to popularize widely. In addition, most existing sand therapy beds do not have a massage function, so it is difficult to better realize the function of physical therapy and health preservation.

Contents of the invention

In order to overcome the above-mentioned shortcomings of the prior art, the object of the present invention is to provide an electric heating fluidized massage sand therapy bed, which has both a massage function and can solve the problem of uneven heating of the sand layer and power consumption of the existing electric heating sand therapy bed. Advanced problems, while adding gas massage function, improve user experience. The invention can also precisely control the temperature of the sand layer, further reducing power consumption. On the premise of heating the sand layer more evenly and improving the effect of sand therapy, the heating time is reduced and the power consumption of the electric sand therapy bed is reduced.

In order to achieve the above object, the technical scheme adopted in the present invention is:

An electric heating fluidized massage sand therapy bed, comprising a bed body 1, a sand therapy tank 2 is arranged in the bed body 1, and the sand therapy tank 2 is divided into a headrest area and a sand therapy area, and it is characterized in that, in the sand therapy area, the And the protective grid 3, the pressurized air pipeline 4 and the carbon crystal heating plate layer 5 are arranged successively below, and the described pressurized air pipeline 4 is connected to the gas booster device, and there are a plurality of outlets for use in the lower side of the pressurized air pipeline 4. Into sand layer, pass into the jet hole 19 of pressurized air.

The top of the bed 1 is provided with a top cover for covering the sand therapy tank 2, and the top cover is sequentially composed of a cloth layer 16, a bamboo mat layer 17, a flame-retardant insulation layer 7, a cloth layer 17 and an ultraviolet extinguisher from the outside to the inside. The germ lamp 18 and the ultraviolet germicidal lamp 18 are electrically connected with the bed body 1 . It can ensure the cleanliness and sanitation of the bed body when not performing sand therapy. At the same time, the sand layer in the bed body can be sterilized.

The bed body 1 is sequentially composed of a decorative shell layer 6 (usually a solid wood board), a flame-retardant insulation layer 7, a reflective aluminum foil layer 8, a carbon crystal heating plate layer 5, and an insulating and heat-conducting layer 9. The compressed air pipeline 4 is located between the insulating and heat-conducting layer 9 and the protective grid 3 .

Described headrest area is provided with pillow case, is provided with pillow 10 on the pillow case, is provided with accumulator and miniature air pump 11 in the pillow case, and described accumulator connects miniature air pump 11 for its power supply.

The micro-air pump 11 and the gas booster are connected in parallel with the pressurized air pipeline 4. In the case of power failure, the micro-air pump 11 supplies air to the pressurized air pipeline 4 to ensure the sand therapy and the user from Get out of the sand.

The pressurized air pipeline 4 is composed of several equal-diameter pipelines connected to each other and located on the same plane.

The protective grid 3 is a grid structure, and the size of the grid can pass sand, but prevent body parts from passing through, thereby protecting the human body. It is made of wood or metal with scald protection.

The air injection holes 19 are evenly arranged along the pipe length direction on the lower side of the pressurized air pipe 4, and the material of the pressurized air pipe 4 is plastic or metal.

A number of temperature sensors 12 are evenly arranged on the inside of the side wall of the bed 1, and a temperature controller 14 is arranged on the outside of the side wall of the bed 1. The temperature sensors 12 are in direct contact with the sand layer to measure the sand therapy tank. 2 The temperature of the inner sand layer realizes the intelligent and precise control of the sand therapy temperature. The temperature controller 14 includes a temperature sensor input interface, a heating power output interface, and a gas pressure control signal output interface. The temperature controller 14 adjusts the carbon crystal heating plate according to the difference between the temperature measured by the temperature sensor 12 and the set temperature. The input power can be adjusted to adjust the temperature of the sand layer and switch between heating mode and heat preservation mode.

A gas pressure controller 15 is arranged outside the side wall of the bed body 1. The gas pressure controller 15 includes a temperature controller input interface and a gas valve control output interface. The point temperature difference outputs the gas pressure adjustment signal, and the gas pressure and flow rate input into the sand layer are adjusted through the gas pressure controller 15, thereby adjusting the fluidity of the sand layer and making the heating of the sand layer more uniform. The hot air flowing from the lower part of the body and the pressure of the moving sand on the body create a very comfortable massage experience.

The lower part of the bed body 1 is provided with rollers 13 for easy movement and a device for controlling the movement and locking of the rollers 13 .

Compared with prior art, the beneficial effect of the present invention is:

First, the sand layer is heated more evenly, saving heating time and power consumption. By passing pressurized air into the sand layer, the fluidity of the sand layer is increased. The increase of fluidity makes the heating of the sand layer change from mainly relying on heat conduction for heat transfer to relying on convection heat transfer for heat transfer. The change of the heat transfer mode greatly enhances the heat transfer between the carbon crystal heating plate 5 and the sand layer, thereby improving the heating efficiency. In addition, the carbon crystal heating plate 5 with very good insulation performance is selected. Under the condition of ensuring the safety of users, the heating plate is directly contacted with the sand layer for heating. The heating method that reduces the intermediate thermal resistance will further improve the heating efficiency. In addition, the pressurized air pipeline 4 is arranged above the carbon crystal heating plate 5 in combination with the design of the lower side air jet opening so that the pressurized air is heated after passing into the sand layer, and the hot air will be heated during the upward surge in the sand layer. The sand layer is continuously heated until it leaves the sand layer. Pressurized air also can blow away the heated sand body on carbon crystal heating plate 5 surface in time, promotes the circulating flow heating of sand layer. Under various optimized designs, the problem of uneven heating of the original electric heating sand therapy bed can be significantly improved. At the same time, it reduces heating time and power consumption, and improves user experience.

Second, add heating and pressurized air massage function to enhance the effect of sand therapy. After the pressurized air flows out from the fumarole, it can be sprayed onto the carbon crystal heating plate 5 surface, and the heat exchange with the carbon crystal heating plate has improved the temperature of passing into the sand layer air. The evenly arranged air jet holes make the human body in the sand layer evenly massaged by the hot air under pressure, which promotes the blood circulation of the human body, ensures the health of the skin, and plays the role of beautifying the body. The carbon crystal heating plate 5 is selected to radiate far-infrared rays outward while heating, which can further improve blood circulation and microcirculation, and improve the effect of sand therapy.

Third, the precise control of the temperature of the sand layer. The temperature sensor 12 arranged inside the side wall of the sand therapy bed can measure the temperature of the contacted sand layer. The temperature controller 14 controls the heating power of the carbon crystal heating plate 5 according to the temperature measured by the temperature sensor 12 and the comparison of the set temperature, and can also send a gas pressure control signal to adjust the fluidity of the sand layer by the gas pressure controller 15 to improve the sand layer temperature inhomogeneity. Through the above design, the temperature of the sand layer can be precisely controlled to make it closer to the set temperature, improving the user's sand therapy experience.

Fourthly, a reflective aluminum foil layer 8 is added to enhance the thermal insulation performance of the sand therapy bed body. A reflective aluminum foil layer 8 is added in the body of the sand therapy bed to reflect the far-infrared rays radiated from the carbon crystal heating plate 5 to the inside of the sand therapy bed during the heating process, thereby reducing heat energy loss of the sand therapy bed. When not heated, it can reflect the far-infrared rays radiated outward by the heated sand layer to the inner side of the sand therapy bed, thereby enhancing the thermal insulation performance of the sand therapy bed. This slows down the temperature drop in the sand therapy bed and saves energy.

Fifth, a protective grille 3 is added to protect the safety of users. A protective grid 11 is added in the sand therapy bed to prevent the user from being injured by touching the carbon crystal heating plate or being stuck in the pressurized air pipeline layer during the sand therapy process. At the same time, the grid structure design can pass through the flowing sand layer and interfere with the flow of pressurized air in the sand layer as little as possible to ensure its heating and massage effects.

The 6th, add storage battery and miniature air pump 11, further guarantee user's safety. Due to the increase in the fluidity of the sand layer, the user may be buried deeper in the sand layer, and the user may not be able to escape by himself when the power is cut off and there is no pressurized gas. In order to solve the above problems, the present invention adds storage battery and miniature air pump 11. In the case of a power failure, the battery can provide power for the micro air pump, and continue to feed pressurized air into the sand layer to ensure that the user can get out in time. In the case of specific needs, the user can continue to perform massage sand therapy when the power is cut off, so as to ensure the sand therapy effect under special circumstances.

Seventh, the overall structure of the system is simple and the cost is low. Compared with the existing electric heating fluidized sand therapy bed, the present invention has no complicated mechanical structure, and adopts the method of feeding pressurized air into the sand layer to enhance the fluidity of the sand layer and enhance the reliability during use. At the same time, the manufacturing cost of the sand therapy bed is reduced, and it is possible to widely apply the electric heating sand therapy bed.

Detailed ways

The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

As shown in Figure 1, the bed body 1 of the sand therapy bed is a sand therapy tank 2, and the sand therapy tank 2 is divided into a headrest area and a sand therapy area. The sand treatment area is provided with a protective grid 3, a pressurized air pipeline 4 and a carbon crystal heating plate layer 5. The headrest area is provided with a pillow box, and a pillow 10 is arranged on the pillow box, and a storage battery and a miniature air pump 11 are arranged in the pillow box. The bed body 1 includes an outer shell layer 6 , a flame-retardant heat-insulating material layer 7 , a reflective aluminum foil layer 8 , a carbon crystal heating plate layer 5 , and an insulating and heat-conducting layer 9 from outside to inside. A number of temperature sensors 12 are evenly arranged inside the side wall of the bed body 1 , and the measured temperature signals are sent to a temperature controller 14 . The lower part of the bed is provided with rollers 13 to facilitate the movement of the bed and a device for controlling the movement and locking of the rollers.

As shown in FIG. 2 , the micro air pump 11 is connected to the pressurized air pipeline 4 through the B port, and the gas booster is connected to the pressurized gas pipeline through the A port. The above-mentioned connection mode is a parallel connection, and its purpose is to continue to feed pressurized air to the sand layer through the micro air pump 11 in the case of power failure, so as to ensure that the user can get out of the sand layer and continue sand therapy in the case of power failure. The micro air pump 11 is powered by a storage battery.

The working principle of the present invention is as follows:

Along the length direction of the pressurized air pipeline 4, there are evenly arranged the air injection holes 19 as shown in Figure 3, and the air injection holes 19 are located at the lower part of the pressurized air pipeline 4, which is at a lateral position. The amount of pressurized air passed through the layer. In the sand layer, pressurized air is passed through the jet hole 19 to increase the fluidity of the sand layer. This makes the heating process of the carbon crystal heating plate to the sand layer change from heat conduction to convection heat transfer, which greatly enhances the heat transfer efficiency. Due to the good insulation of the carbon crystal heating plate and the protection grid, the direct contact heating between the carbon crystal heating plate and the sand layer can reduce the thermal resistance and further enhance the heat exchange effect. The pressurized air pipeline 4 is arranged on the carbon crystal heating plate 5 top and can make the pressurized air blow off the carbon crystal heating plate surface layer in time and has heated the sand layer while also heating the pressurized air. While the heated air surges upwards to heat the sand layer, it also massages the human body in the sand layer, further enhancing the therapeutic effect.

The obliquely downward design of the jet hole 19 can avoid sand grains from blocking the orifice as much as possible. Under the situation of no ventilation, the fluidity of the sand layer is very small, and the sand grains are blocked at the orifice of the jet hole 19 because of mutual friction, but the sand grains can not continue to enter the jet duct. Of course, it is not ruled out that a very small amount of sand particles may enter the air injection pipe, but these sand particles can be blown out during the air injection process of the air injection pipe. At the same time, due to the two-way ventilation pipeline design, there is no accumulation of sand particles at one end. For sand blockages that cannot be discharged, regular cleaning can be used to achieve continuous operation of the equipment. Also can offer the larger hole that has plug to discharge accumulated sand in the lower part in the middle of the jet pipe.

As shown in Figure 4, a temperature controller 14 and a gas pressure controller 15 are arranged on the outside of the side wall of the bed body 1. The precise control principle of the sand layer temperature is as follows: the temperature sensors 12 evenly distributed on the inside of the bed body side wall can be relatively accurate. Measure the temperature of different parts of the sand layer accurately. When the average temperature measured by each temperature sensor 12 is lower than the set temperature by more than 3° C., switch from the heat preservation mode to the heating mode. Temperature controller 14 increases the input power of carbon crystal heating plate, improves the temperature of sand layer, makes it close to setting temperature. When the average value of the measured temperature is greater than the set temperature by more than 3° C., the temperature controller cuts off the power supply of the carbon crystal heating plate layer 5 . When the difference between any two of the measured temperatures is greater than 5° C., the temperature controller 14 outputs a gas pressure adjustment signal to the gas pressure controller 15 . Then the gas pressure controller 15 adjusts the intake valve to increase the pressure and flow of the pressurized gas, enhance the fluidity of the sand layer, and make the temperature of each part of the sand layer tend towards uniformity. Controlling based on the above-mentioned temperature control logic can realize precise control of the temperature of the sand layer. The gas pressure controller 15 can independently control the gas pressure and flow rate leading into the sand layer. The gas pressure is mainly controlled based on the user's experience of gas massage comfort.

As shown in Figure 5, the top cover is mainly made up of cloth layer 16, bamboo mat layer 17, flame retardant insulation layer 7 and ultraviolet sterilizing lamp 18. The function of the top cover is mainly to ensure the cleanliness and sanitation of the sand therapy tank when it is not in use, and it also has a bactericidal effect. The purpose of adding bamboo mat 17 is to ensure the shape of the top cover. And the effect of adding the fire-retardant insulation layer 7 is to reduce the heat loss in the sand therapy tank 2, and ensure that the sand layer can rise to the set temperature rapidly when the next user uses it.

In the present invention, parameters such as bed size, sand layer thickness, air pressure and flow velocity are balanced according to energy saving and user experience.

In terms of energy saving, the thickness of the sand layer should be reduced as much as possible, thereby reducing the heating heat and jet pressure. In the design of the sand therapy bed, it is usually enough to bury the body in the sand layer.

From the perspective of user experience, in actual use, users often adjust the thickness of the sand layer according to their own needs, so as not only to meet the needs of basic sand therapy, but also to increase the experience and fun of use.

In the currently proposed embodiment, the air pressurization device can be replaced by a pressurized air pump combined with a gas cylinder, the available power is 1500W, and the available pressure is 0.7-0.3MPa.

In summary, the present invention provides an electric heating sand therapy bed with simple structure, high efficiency and energy saving, and massage function. The method of feeding pressurized air into the sand layer enhances the fluidity of the sand layer and improves the heating efficiency. In addition, users can adjust the intensity of gas massage according to their own needs, further enhancing the physical therapy effect of sand therapy.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection of the present invention. within range.
