Field of Invention
This utility model belongs to the technical field of electric blowers, and specifically relates to a far-infrared (FIR) light heated ceramic electric blower for physiotherapeutic use.
Background of the Invention
The electric blower has been used for more than a century for drying hair and other items. At present, a common electric blower mainly consists of a housing, an electric motor, fan blades, a heating element, an insulation bracket, a power switch and a power cord, wherein the heating element is typically made of iron nickel chromium wires. Usually, the iron nickel chromium wires are spirally wind around the insulation bracket. According to the physics of the spiral law for conductors, such an iron nickel chromium wire structure generates a large amount of electromagnetic waves. However, the iron nickel chromium wire has some weaknesses, such as low thermal efficiency, high energy consumption and easy breaking. Under the macro environment where the energy-conserving and eco-friendly low-carbon lifestyle is promoted, it is very important to manufacture an electric blower that is energy saving, health caring and environment protecting.
This utility model is intended to overcome the abovementioned defects and imperfections.
This utility model adopts the following technical solution to achieve its purpose:
A far-infrared (FIR) light heated ceramic electric blower for physiotherapeutic use comprises a housing and fan blades. In the housing there is an air inlet and an air outlet. Between the fan blades and the air outlet there is a heating element, which is an FIR heating light tube. The FIR heating light tube is accommodated within the inner chamber of the housing with a mica bracket. The circuit of the FIR heating light tube is connected with a hot air switch.
The housing consists of a front cylinder, a rear cylinder and a rear cover. The front cylinder and the rear cylinder are snap-fit together to form an inner chamber. There is an air outlet at the top end of the front cylinder. The rear cover is connected to the tail of the rear cylinder and has an air inlet.
The FIR light heated ceramic electric blower for physiotherapeutic use also comprises fitting strips, an air outlet ring and a hollow inner cylinder. The inner cylinder is engaged and disposed within the inner chamber of the housing, and the top end of the inner cylinder is spaced with the inner wall of the front cylinder. The air outlet ring is mounted at the top end of the inner cylinder and an air outlet ring has a set of parallel spaced deflectors. The fitting strips are engaged and disposed between the top end of the inner cylinder and the top end of the front cylinder.
The FIR light heated ceramic electric blower for physiotherapeutic use also comprises honeycomb ceramics and a step-down heating coil. The FIR heating light tube and the step-down heating coil are both fixed to the mica bracket. The FIR heating light tube and the step-down heating coil are in circuit connection. The step-down heating coil and the hot air switch are in circuit connection.
The mica bracket consists of a set of radially disposed panels, which are connected with each other on the axis of the mica bracket.
The FIR light heated ceramic electric blower for physiotherapeutic use also comprises a rubber gasket, an electric motor and an electric motor bracket. The electric motor is fixed to the inner wall of the housing with the electric motor bracket. The electric motor is connected with fan blades on one end and connected with the rubber gasket on the other end. The FIR light heated ceramic electric blower for physiotherapeutic use also comprises a cold air button, a cold air switch and a power switch. The housing has a handle, on which the cold air button, the cold air switch and the power switch are mounted, and the cold air button and the cold air switch are in circuit connection.
This electric blower has the following advantages: 1. The FIR light tube of this electric blower is electrified to heat, and all of the heat is blown to the air outlet under the pressure from the rotating fan blades driven by an electric motor. The FIR ray generated by the FIR light tube and ceramics has the shortest wavelength and the strongest penetration, thus effectively helping to relieve soreness and pain. Unlike ultraviolet ray, infrared ray does not burn the skin. The infrared light can be used for INFRACARE for one time or many times every day according to personal needs and purpose. Adopting the high-power halogen light tube technology, the FIR heating light tube can quickly and effectively achieve the result of relieving the soreness and discomfort in the joints and muscles. 2. Honeycomb ceramics are disposed between the FIR heating light tube and the air outlet. On one hand, the holes evenly distributed on the honeycomb ceramics are similar to those on the honeycomb and ensure even distribution of the heat. On the other hand, the honeycomb ceramics begins to heat and send out infrared rays after absorbing the heat from the infrared heating light tube to perform health care physiotherapy on human body. 3. The mica bracket consists of a set of radially disposed panels, which are connected with each other on the axis of the mica bracket, so that the air can go through smoothly in the axial direction with minimum air resistance and the path for air heating is extended for a high heat utilization rate. This electric blower is an ideal choice as it does not need any open fire while heating and it also has other advantages such as safety, low energy consumption and ease of operation.
Other objectives of the disclosure will become apparent to those skilled in the art once the invention has been shown and described. The manner in which these objectives and other desirable characteristics can be obtained is explained in the following description and attached figures in which:
It is to be noted, however, that the appended figures illustrate only typical embodiments of this invention and are therefore not to be considered limiting of its scope, for the invention may admit to other equally effective embodiments that will be appreciated by those reasonably skilled in the relevant arts. Also, figures are not necessarily made to scale but are representative.
Below is further detailed description of this utility model by reference to the drawings.
An FIR light heated ceramic electric blower for physiotherapeutic use consists of a housing 1, fitting strips 2, an air outlet ring 3, an inner cylinder 4, an FIR heating light tube 5, a mica bracket 6, honeycomb ceramics 7, a step-down heating coil 9, a rubber gasket 10, an electric motor 11, an electric motor bracket 12, fan blades 13, a hot air switch 14, a cold air button 15, a cold air switch 16 and a power switch 17.
The housing 1 consists of a front cylinder 1a, a rear cylinder 1b and a rear cover 1c. The front cylinder 1a and the rear cylinder 1b are snap-fit together to form an inner chamber. There is an air outlet 1e at the top end of the front cylinder 1a. The rear cover 1c is connected to the tail of the rear cylinder 1b and has an air inlet 1d.
The inner cylinder 4 is engaged and disposed within the inner chamber of the housing 1, and the top end of the inner cylinder 4 is spaced with the inner wall of the front cylinder 1a. The air outlet ring 3 is mounted at the top end of the inner cylinder 4 and an air outlet ring 3 has a set of parallel spaced deflectors. The fitting strips 2 are engaged and disposed between the top end of the inner cylinder 4 and the top end of the front cylinder 1a.
