Description
Technical Field
The utility model relates to a phototherapy equipment technical field, in particular to heat radiation structure of phototherapy equipment.
Background
At present, phototherapy equipment is mainly applied to the medical and beauty industry, a semiconductor light-emitting device is mostly adopted as a light source, firstly, due to the problem of conversion efficiency of the semiconductor light-emitting device, a large part of electric energy is converted into heat, and the semiconductor is sensitive to temperature, a heat dissipation structure is not good, so that the service life of the light-emitting device is influenced; secondly, many phototherapy devices in the medical and cosmetic industries are in contact with the human body, and the temperature of the part in contact with the human body determines the customer experience of the product, so that the product may feel cool in winter and hot in summer; therefore, heat dissipation of the phototherapy device is very important.
Phototherapy equipment that contacts with human body in the existing market, the heat dissipation problem has not been considered for the majority, and the product of heat dissipation module has rarely increased, or just like ordinary electronic product, only considered the heat dissipation requirement of device, and do not consider user's use experience demand, to this kind of condition, await further improvement.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a heat radiation structure of phototherapy equipment that has simple structure, and is with low costs, and good reliability, simultaneously can effectual extension luminous component's life
In order to solve the technical problem, the utility model discloses a technical scheme does:
a heat dissipation structure of phototherapy equipment comprises a shell; a cavity arranged in the shell; and the fan is arranged at the outlet of the cavity, a circuit board is arranged in the cavity, and a light-emitting part is arranged on the circuit board.
Preferably, the inner wall of the cavity is provided with dustproof soft rubber.
Preferably, a temperature sensor is arranged on the inner wall of the cavity and close to the outlet of the cavity.
Preferably, a transparent member is disposed at the outlet of the cavity and below the fan.
Adopt above-mentioned technical scheme, through at shell installation fan, can effectual improvement luminous component heat dissipation and with the condition of human contact surface temperature control, just the utility model has the advantages of simple structure, with low costs, and good reliability, simultaneously can effectual extension luminous component's life.
Drawings
Fig. 1 is a schematic view of the work flow of the present invention.
In the figure, 1-fan, 2-shell, 3-circuit board, 4-luminous component, 5-dustproof soft glue, 6-temperature sensor, 7-transparent component, 8-optical path and 9-cavity.
Detailed Description
The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The utility model discloses in, a heat radiation structure of phototherapy equipment, as shown in fig. 1, has seted up cavity 9 at 2 inner walls of shell, installs fan 1 at the opening part of cavity 9, installs circuit board 3 in cavity 9, installs luminous component 4 on circuit board 3. In the present embodiment, the light emitting part 4 is an LED lamp.
Wherein, the inner wall of the cavity 9 is provided with a dustproof soft glue 5, and the dustproof soft glue 5 is arranged on one side of the light emitting component 4. The dustproof soft rubber 5 can reduce the accumulation of dust in a heat dissipation air passage, so that the light emitting component 4 can be protected to normally work.
Secondly, a temperature sensor 6 is also arranged on the inner wall of the cavity 9, and the temperature sensor 6 is close to the outlet of the cavity 9.
A transparent member 7 is provided on the side of the circuit board 3 having the light-emitting part 4.
The heat dissipation air passes through both sides of the circuit board 3, and a temperature sensor 6 is provided at an air outlet of the cavity 9 or a portion contacting with a human body. The rotating speed of the fan 1 is controlled through the temperature signal of the temperature sensor 6 while the heat dissipation requirement of the semiconductor light emitting component 4 is met, so that the purpose of controlling the temperature of the part of the transparent piece 7 in contact with a human body is achieved, the experience of an operator is greatly improved, and the operator does not feel uncomfortable in the using process in winter or summer. Meanwhile, the temperature can be controlled within the range required by the laws and regulations so as to ensure the use safety of the human body. The utility model discloses an structurally increase dustproof flexible glue 5 for because the dust that the cooling air brought can not influence and contact by confined light path 8, thereby reduce the influence to optical parameter, be favorable to the performance of guarantee product.
In a specific case, the positions of the air inlet and the air outlet in fig. 1 can be interchanged, that is, the flowing direction of the air is opposite to that in fig. 1, which is suitable for summer, when the ambient temperature is higher, it is desirable to supply air from one side of the transparent member, and when the ambient temperature is close to the skin, the user experience is better.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
