Description

Technical Field

[0001] The present invention relates to an improved device for a phototherapy machine, in particular to a phototherapy machine device capable of cleaning a cabin and automatically draining sewage. Background Art

[0002] first, Figure 1 A and Figure 1 As shown in B, it is the inventor's previous invention, Taiwan Announcement No. I759217 "Safety Monitoring and Management System of Phototherapy Machine", which includes a cabin 80, the internal space of which can be used to accommodate the user's body, and a plurality of infrared light sources 81 composed of halogen lamps are installed in the cabin 80. The thermal radiation energy generated by the infrared light source 81 is used to irradiate the human body inside the cabin 80, so as to achieve the purpose of improving local blood circulation and relieving muscle fatigue and soreness.

[0003] Secondly, tests that require specimens, such as blood tests or urine tests, all look for clues of changes in the body from body fluids or metabolites in order to determine the body's health status. Sweat is also a metabolite of the human body and contains a lot of information about body changes that can be used for testing. However, the sweat secreted by the human body may vary depending on the factors that cause sweating (the amount of exercise or temperature or the collection process is mixed with other substances, such as water vapor, etc.), causing the information in the sweat representing the body's health status to change significantly. This change will lead to inaccurate sweat testing.

[0004] Based on the above purpose, the inventor's previous invention, Taiwan Publication No. I783471 "Infrared Irradiation Cabin Capable of Collecting Sweat", discloses that a number of infrared light sources are installed inside the cabin, and the human body can be placed inside the cabin in a lying or sitting position, and the thermal radiation energy generated by the infrared light source can be used to irradiate the human body inside the cabin, and the sweat discharged by the human body due to the infrared irradiation flows to the sweat collection port at the lower end of the cabin floor by gravity, and drips into the sweat collection box for collection, thereby improving the accuracy of the sweat test. However, it was found that the sweat of the previous user will remain on the cabin floor for sweat collection, which will not only cause the next user to have a sweat odor when using it, causing the trouble of a poor use environment, but also the sweat of the previous user will remain, which will lead to inaccurate sweat testing of the person concerned, so there is still room for improvement.

[0005] In view of the above problems, the inventors have been actively researching and improving the invention in order to effectively solve the above problems. Summary of the invention

[0074] The following is a description of the implementation of the present invention by means of specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied by means of other different specific embodiments, and the details in this specification can also be modified and changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0075] First, see Figure 1 to Figure 6 As shown, a preferred feasible embodiment of the present invention includes: a cabin 50, having a cabin door 51 and an inclined cabin bottom plate 52, the internal space 53 of the cabin 50 can accommodate a human body, a sweat collection port 521 is provided at the lower end of the cabin bottom plate 52, and a sweat collection box 60 is provided below the cabin bottom plate 52 relative to the sweat collection port 521; and at least one irradiation lamp body 10, installed in the cabin 50, using the thermal radiation energy of the infrared light source generated by the irradiation lamp body 10 to irradiate the human body located inside the cabin 10, and the sweat discharged from the human body flows to the sweat collection port 521 at the lower end of the cabin bottom plate 52 due to gravity, and drips into the sweat collection box 60 for collection.

[0076] Since the sweat collected by the present invention is discharged through infrared irradiation, the factors causing sweating (exercise volume and temperature) are unchanged, so the information representing the health status of the body in the large amount of sweat collected is extremely stable, and the sufficient amount of sweat and the unchanged sweating factors are helpful to improve the accuracy of the sweat test. However, the residual sweat or metabolites of the previous user in the cabin will affect the hygiene and detection accuracy of the next user.

[0077] The main feature of the present invention is that: a bottom plate cleaning device 80 is arranged above the bottom plate 52, and includes: at least one cleaning nozzle 81 installed in the cabin body 50, and a cleaning liquid supply device 83 is arranged below the bottom plate 52, and the cleaning liquid is delivered to the cleaning nozzle 81 via a pipeline 82 to remove sweat remaining on the bottom plate 52, and the cleaned sewage flows to the sweat collecting port 521 at the lower end of the bottom plate 52 due to natural gravity.

[0078] A sewage collection box 70 with a larger volume than the sweat collection box 60 is provided below the sweat collection port 521. The top of the sewage collection box 70 is formed with an opening 74. The sweat collection box 60 is placed in the sewage collection box 70 in a removable and detachable manner. A water pump 71 and a water level sensor 72 are provided inside the sewage collection box 70. When the sewage in the sewage collection box 70 reaches a predetermined water level, the water pump 71 automatically discharges the sewage through a drain pipe 73. In this way, after the sweat collection of the previous user is completed, the bottom plate cleaning device 80 can automatically clean the residual sweat or metabolites to ensure the hygiene of the next user and the accuracy of the detection.

[0079] In this embodiment, the irradiation lamp bodies 10 are arranged in parallel to form an irradiation surface, and are respectively arranged on the left and right sides of the cabin 50 and under the cabin bottom plate 52; in addition, a rectangular irradiation lamp body 10a may also be arranged on the upper inner side of the cabin 50, but it is not limited to this. In this embodiment, the cabin bottom plate 52 is made of a light-transmitting material, such as tempered glass, acrylic, etc. In this way, the infrared light source generated by the irradiation lamp body 10 can penetrate the cabin bottom plate 52 to irradiate the human body inside the cabin 10.

[0080] For further information, see Figure 5 to Figure 7 As shown, in a preferred embodiment of the present invention, the irradiation lamp body 10 includes: a shell 11, whose cross-section is concave to form a receiving space 12, and the bottom of the shell 11 is provided with at least one mounting hole 13; at least one lamp holder 14, and the lamp holder 14 is combined with the bottom of the shell 11 corresponding to the mounting hole 13; at least one halogen lamp 15, which is combined with the lamp holder 14, and the upper section of the halogen lamp 15 protrudes into the receiving space 12; a light-transmitting plate 16, which is arranged on the top of the elongated shell 11; left and right covers 17, which are respectively arranged on the left and right sides of the shell 11, and the left and right covers 17 are provided with flow holes 18 relative to the receiving space 12; however, it is found that the halogen lamp 15 belongs to the prior art (Prior Art), which is not the patent purpose of this application, and it is not necessary to repeat it.

[0081] In this embodiment, the circulating cooling liquid 20, such as Figure 5As shown, it includes: a circulation pipeline 30, whose input end 31 and output end 32 are respectively connected to the flow holes 18 of the left and right covers 17, and is used to inject circulating cooling liquid 20 into the accommodating space 12 of the irradiation lamp body 10 for circulation, so as to cool the halogen lamp 15 and make the irradiation light beam emitted by it be filtered by the flowing circulating cooling liquid 20 before being projected out by the light-transmitting plate 16.

[0082] In this embodiment, the cooling liquid temperature automatic control device 40 is as follows: Figure 6 As shown, it includes: a temperature sensor 41, which is arranged in the irradiation lamp body 10 and is used to detect the temperature of the circulating cooling liquid 20 in the accommodating space 12; a controller 42, which includes a microprocessor 421 and a memory 422, which is electrically connected to the temperature sensor 41 and calculates the temperature of the circulating cooling liquid 20; a flow rate sensor 43, which is arranged on the circulation pipeline 30 and is used to detect the flow rate of the circulating cooling liquid 20 and transmit the value to the controller 42; a flow control valve 44, which includes a first control valve 441 and a driving element 442, and the driving element 442 receives the command signal of the controller 42 to control the first control valve 441 to adjust its flow rate ; a water pump 45, which is arranged on the circulation pipeline 30 and is electrically connected to the controller 42, and is used to pump the circulating cooling liquid 20 for circulation; a cooling device 46, which is arranged on the circulation pipeline 30, and is used to cool the circulating cooling liquid 20 flowing out of the output end 32; and the controller 42 calculates the optimal flow rate of the circulating cooling liquid 20 entering and exiting the accommodating space based on the temperature of the circulating cooling liquid 20 in the accommodating space 12 and the value of the flow rate sensor 43, in a proportional mode in which the higher the temperature, the faster the flow rate, and controls the flow rate of the circulating cooling liquid 20 by the flow control valve 44 to obtain the set temperature of the circulating cooling liquid 20.

[0083] Based on this, the circulating cooling liquid 20 is used to filter out harmful wavelengths of ultraviolet light and blue light in the irradiation light beam emitted by the halogen lamp 15. In this embodiment, the harmful wavelengths include wavelengths below 480nm in the irradiation light beam emitted by the halogen lamp 15.

[0084] In this embodiment, the flow velocity sensor 43 may include a velocity meter or a flow meter. If it is a velocity meter, the flow velocity of the circulating cooling liquid 20 can be directly measured; if it is a flow meter, the flow velocity of the circulating cooling liquid 20 can be calculated by the controller 42 through the cross-sectional area of ​​the circulation pipeline 30; since such flow velocity sensors 43 are all mature commercial products, they are not described in detail.

[0085] In this embodiment, the driving element 442 of the flow control valve 44 includes any one of an electromagnetic solenoid, a micro motor or a piezoelectric element. However, the flow control valve 44 belongs to the prior art, and its detailed structure and principle are not described in detail. In this embodiment, the flow rate sensor 43 and the flow control valve 44 include independent, separate structures or a combination of the two.

[0086] In this embodiment, the cooling device 46 includes a cold heat exchanger. Thus, the controller 42 calculates the optimal flow rate of the circulating cooling liquid 20 in and out of the accommodating space 12 according to the temperature of the circulating cooling liquid 20 in the accommodating space 12 and the value of the flow rate sensor 43, in a proportional mode that the higher the temperature, the faster the flow rate. The flow rate of the circulating cooling liquid 20 is controlled by the flow control valve 44 to obtain the set temperature of the circulating cooling liquid 20, and the halogen lamp 15 is directly contacted to cool the heat dissipation system.

[0087] like Figure 6 As shown, in this embodiment, the present invention also includes an external supply liquid 47 entering the cooling device 46 or the circulation pipeline 30 via a liquid replenishing pipe 48, and the liquid replenishing pipe 48 is provided with a second control valve 49, and the second control valve 49 is electrically connected to the controller 42.

[0088] Fig. 8A and Figure 8B A schematic diagram of the wavelength of the irradiation beam of the present invention is disclosed, which displays data such as illumination, irradiance, and color temperature, and it shows that the harmful wavelengths below 480nm in the irradiation beam emitted by the halogen lamp 15 are significantly reduced, such as Figure 7 That is, the present invention can filter out harmful wavelengths of ultraviolet light and blue light in the irradiation light beam emitted by the halogen lamp 15 by using the circulating cooling liquid 20 .

[0089] With the help of the above-mentioned technical means, the cooling liquid temperature automatic control system 40 of the present invention is based on the temperature of the circulating cooling liquid 20 in the irradiation lamp body 10 and the value of the flow rate sensor 43, so that the flowing circulating cooling liquid 20 directly contacts and cools the halogen lamp 15, and the optimal flow rate of the circulating cooling liquid 20 in and out is calculated in a proportional mode that the higher the temperature, the faster the flow rate, and then the flow control valve 44 controls the flow rate of the circulating cooling liquid 20 to directly contact and cool the halogen lamp 15 in the optimal heat dissipation mode, so as to solve the problem that the existing infrared lamp tube has poor heat dissipation effect and causes the halogen lamp to be easily damaged; thereby improving the reliability and service life of the product. More importantly, the present invention uses the flowing circulating cooling liquid 20 to filter out harmful wavelengths of ultraviolet light and blue light in the irradiation light beam emitted by the halogen lamp 15 to prevent damage to human skin and blue light eyes.

[0090] In this embodiment, the irradiation lamp body 10 is configured as an elongated body, but is not limited thereto; the irradiation lamp body 10 may also be configured as a rectangular body, a circular body, a polygonal body, or other geometric bodies. Furthermore, the irradiation lamp body 10 may be installed in a vertical, horizontal, diagonal, or inclined direction on the inner wall of a phototherapy machine, a seat, an interior decoration wall, a ceiling, or other forms of use.

[0091] With the help of the above technical means, the present invention has the following improved effects that need to be further explained:

[0092] 1. The present invention can automatically clean or disinfect the sweat or metabolites left by the previous user in the cabin 50 to ensure the hygiene of the next user and the accuracy of detection.

[0093] Second, the present invention can collect the wastewater after cleaning residual sweat or metabolites and automatically discharge it, which is hygienic and convenient to use.

[0094] 3. The present invention uses the flowing circulating cooling liquid 20 to directly contact and cool the halogen lamp 15, and calculates the optimal flow rate of the circulating cooling liquid in and out in a proportional mode where the higher the temperature, the faster the flow rate, so as to solve the problem that the existing infrared lamp tube has poor heat dissipation effect, causing the halogen lamp 15 to be easily damaged; thereby improving the product reliability and service life. More importantly, the present invention uses the flowing circulating cooling liquid 20 to filter out harmful wavelengths of ultraviolet light and blue light in the irradiation light beam emitted by the halogen lamp 15 to prevent damage to human skin and blue light eyes.

[0095] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form.
