Description

Technical Field

[0001] The utility model relates to the technical field of infrared physiotherapy instruments, in particular to an anti-scalding cover for an infrared physiotherapy instrument. Background Art

[0002] The infrared physiotherapy instrument is used for large-area irradiation. The wavelength band is determined according to the absorption peak measured by the human body infrared absorption spectrum. The infrared radiation emitted by the red light treatment head can provide activation energy for cells after being absorbed by the cells, enhance the repair ability, and promote the biological conversion function. At the same time, the infrared physiotherapy instrument generates a thermal effect, which can be absorbed by living tissues and has functions such as improving local tissue ischemia and relieving muscle spasm.

[0003] The Chinese utility model patent with the existing publication number CN204563332U discloses an infrared physiotherapy instrument, which includes an infrared generating device and a support frame. The infrared generating device is fixed on the support frame, and the infrared generating device is controlled by a control instrument. The infrared generating device includes a lamp cover and an infrared generating body.

[0004] The above-mentioned existing technical solutions have the following defects: during the use of the infrared physiotherapy instrument, it is easy for people to touch the front outer edge of the lamp cover. The lamp body of the existing infrared physiotherapy instrument generates a large amount of heat, and a lamp cover is generally provided outside for protection. The material of the lamp cover is generally metal. Although it can ensure high structural strength, it is easily heated by the lamp body, resulting in easy scalding when people touch the front outer edge of the lamp cover. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present utility model is to provide an anti-scalding cover for an infrared physiotherapy instrument, which can insulate the outer edge of the lamp cover and avoid scalding caused by accidental touch by people.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions: the anti-scalding cover for an infrared physiotherapy instrument includes a front cover and a rear cover. The rear cover includes a plurality of metal wires. The outer edge of the front cover is coated with a heat insulation ring made of heat insulation material, and the heat insulation ring is inwardly converging towards the rear cover.

[0007] Through the above technical solutions, the heat insulation ring plays a role in heat insulation and anti-scalding at the outer edge of the front cover, and the heat insulation ring is inwardly converging towards the rear cover, which can expand the covering area of the heat insulation ring and further improve the anti-scalding range.

[0008] Preferably, an extension ring is fixed on the side of the heat insulation ring away from the rear cover.

[0009] Through the above technical solutions, the extension ring is on the front of the heat insulation ring, further increasing the blocking effect and improving the heat insulation ability.

[0010] Preferably, the extension ring includes a flared ring and a constricted ring fixed to the ring opening of the flared ring.

[0011] Through the above technical solution, due to the shape of the extension ring formed by the combination of the flared ring and the constricted ring, air can exist between the heat insulation ring and the flared ring, and air can also exist between the flared ring and the constricted ring. Since the heat conduction ability of air is very poor, the heat insulation effect is further improved, avoiding scalding when personnel touch it. On the other hand, when personnel press the constricted ring, the constricted ring can be close to the flared ring, and at the same time, the flared ring can also deform towards the heat insulation ring, producing a good buffering effect. When personnel hit the front edge of the front cover, the possibility of personnel being injured can be reduced.

[0012] Preferably, the heat insulation ring, the flared ring, and the constricted ring are integrally fixed.

[0013] Through the above technical solution, the integrally fixed heat insulation ring, flared ring, and constricted ring have better integrity, a smoother and more beautiful appearance, and are not easily separated and broken.

[0014] Preferably, the materials of the flared ring and the constricted ring are silicone or rubber.

[0015] Through the above technical solution, the flared ring and the constricted ring have good elasticity and are easy to deform.

[0016] Preferably, a heat insulation strip is provided outside the rear cover, and the heat insulation strip is attached to the outside of the metal wire of the rear cover.

[0017] Through the above technical solution, by setting the heat insulation strip, the metal wire of the rear cover can also be heat-insulated, avoiding scalding caused by personnel directly contacting the high-temperature metal wire.

[0018] Preferably, an installation groove for embedding the metal wire is provided in the heat insulation strip.

[0019] Through the above technical solution, after the metal wire is clamped into the installation groove by the deformation of the heat insulation strip, the heat insulation strip and the metal wire can be combined and fixed, and it is not easy for the heat insulation strip and the metal wire to spontaneously separate, and the installation is simple and fast.

[0020] Preferably, the heat insulation strip is fixed to the heat insulation ring.

[0021] Through the above technical solution, fixing one end of the heat insulation strip to the heat insulation ring can improve the stability of this end of the heat insulation strip and avoid warping of this end of the heat insulation strip.

[0022] Preferably, a lamp holder is fixed to the tail of the rear cover, and a heat insulation sleeve is sleeved outside the lamp holder.

[0023] Through the above technical solution, the lamp holder at the tail of the rear cover is wrapped by the heat insulation sleeve, thereby preventing scalding when personnel touch the lamp holder.

[0024] In summary, the beneficial effects of the present utility model compared with the prior art are as follows:

[0025] 1. By providing a heat insulation ring, since the material of the heat insulation ring has much lower thermal conductivity than that of metal, it can avoid scalding caused by accidental contact by personnel.

[0026] 2. The heat insulation ring has a large covering area and good protection effect.

[0027] 3. By providing an extension ring composed of a flared ring and a tapered ring, the buffering and heat insulation effects at the front edge of the front cover can be further improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] The following further describes the present utility model in detail Figures 1-4 with reference to the accompanying drawings. First Embodiment

[0034] Referring to Figure 1 , an anti-scalding cover for an infrared physiotherapy instrument disclosed by the present utility model includes a front cover 1 and a rear cover 2. The front cover 1 and the rear cover 2 are combined to form a complete cover body. The front cover 1 and the rear cover 2 are assembled in any manner in the prior art, and the cover body protects the lamp body of the infrared lamp therein. Among them, the front cover 1 is located in front of the irradiation position of the lamp body, and the front surface of the front cover 1 mentioned in this application is the side where the light exits from the lamp body.

[0035] The front cover 1 is provided with a plurality of hollow holes to reduce the blockage of light. The rear cover 2 includes a plurality of metal wires. The plurality of metal wires are arranged in a circular array outside the lamp body, playing a protective role and leaving a large amount of heat dissipation space. It should be noted that neither the front cover 1 nor the rear cover 2 is in contact with the internal lamp body. First, heat is blocked through the air to reduce the direct transfer of the heat of the lamp body to the front cover 1 and the rear cover 2.

[0036] Among them, the diameter of the rear cover 2 gradually shrinks in the direction away from the front cover 1, so that the position with the largest diameter of the rear cover 2 is located at the end close to the front cover 1.

[0037] Referring to Figure 1 and Figure 2 , a heat insulation ring 3 made of heat insulation material is covered on the outer edge of the front cover 1, and the heat insulation ring 3 is inwardly closed towards the rear cover 2. The heat insulation ring 3 plays a role in heat insulation and anti-scalding at the outer edge of the front cover 1, and the heat insulation ring 3 is inwardly closed towards the rear cover 2, which can expand the covering area of the heat insulation ring 3, further improve the anti-scalding range, and can improve the installation stability of the heat insulation ring 3 to prevent the heat insulation ring 3 from falling off from the front of the front cover 1. The material of the heat insulation ring 3 can adopt any heat insulation material in the prior art, such as silica gel, rubber, plastic, etc. with poor thermal conductivity. When the heat insulation ring 3 adopts a flexible material, it can be installed by stretching, and both disassembly and assembly are relatively convenient.

[0038] An extension ring 4 is fixed on the side of the heat insulation ring 3 away from the rear cover 2. The extension ring 4 includes a flared ring 41 and a constricted ring 42 fixed to the ring opening of the flared ring 41. The extension ring 4 is fixed to the heat insulation ring 3 through the ring opening of the flared ring 41. The materials of the flared ring 41 and the constricted ring 42 are silica gel or rubber and can be deformed. The heat insulation ring 3, the flared ring 41, and the constricted ring 42 are integrally fixed; more preferably, the heat insulation ring 3, the flared ring 41, and the constricted ring 42 are integrally formed of silica gel material, with better integrity, smoother and more beautiful appearance, and not easily separated and broken.

[0039] The extension ring 4 forms a structure similar to a corrugated pipe through the combined shape of the flared ring 41 and the constricted ring 42. Air can exist between the heat insulation ring 3 and the flared ring 41, and air can also exist between the flared ring 41 and the constricted ring 42. Since the heat conduction ability of air is very poor, the heat insulation effect is further improved to prevent scalding when people touch it.

[0040] On the other hand, when a person presses the constricted ring 42, the constricted ring 42 can be close to the flared ring 41, and at the same time, the flared ring 41 can also deform towards the heat insulation ring 3, generating a good buffering effect. When a person hits the front edge of the front cover 1, the possibility of personal injury can be reduced.

[0041] Only one extension ring 4 is provided in this embodiment. In other embodiments, multiple extension rings 4 can be provided as needed. The multiple extension rings 4 are combined end to end in the front and rear to form a corrugated pipe, thereby further improving the buffering and heat insulation effects.

[0042] The implementation principle of the anti-scald cover of the infrared physiotherapy device in this embodiment is as follows: By setting the heat insulation ring 3, since the material of the heat insulation ring 3 has much lower thermal conductivity than that of metal, it can avoid scalding caused by accidental contact by personnel, and the covering area of the heat insulation ring 3 is relatively large, so the protection effect is good. By setting the extension ring 4 composed of the flared ring 41 and the constricted ring 42, the buffering and heat insulation effects at the front edge of the front cover 1 can be further improved. Embodiment 2

[0043] An anti-scald cover for an infrared physiotherapy device. The difference between Embodiment 2 and Embodiment 1 is that:

[0044] Referring to Figure 3 , a heat insulation strip 5 is provided outside the rear cover 2, and the heat insulation strip 5 is attached to the outside of the metal wire of the rear cover 2. An installation groove 51 for embedding the metal wire is provided inside the heat insulation strip 5, and the installation groove 51 is a constricted groove. By means of the installation groove 51, it is convenient to install the heat insulation strip 5 on the metal wire of the rear cover 2. After the metal wire is clamped into the installation groove 51 through the deformation of the heat insulation strip 5, the heat insulation strip 5 and the metal wire can be combined and fixed, and it is not easy for the heat insulation strip 5 and the metal wire to spontaneously separate.

[0045] Preferably, the heat insulation strip 5 is fixed to the heat insulation ring 3. Fixing one end of the heat insulation strip 5 to the heat insulation ring 3 can improve the stability of this end of the heat insulation strip 5 and prevent warping of this end of the heat insulation strip 5.

[0046] During normal use, it is not easy for personnel to touch the metal wire of the rear cover 2. However, in this embodiment, by setting the heat insulation strip 5, the metal wire of the rear cover 2 can also be heat-insulated, avoiding scalding caused by personnel directly contacting the high-temperature metal wire. Embodiment 3

[0047] An anti-scald cover for an infrared physiotherapy device. The difference between Embodiment 3 and Embodiment 1 is that:

[0048] Referring to Figure 4 , a lamp holder 21 is fixed to the tail of the rear cover 2. The lamp holder 21 is a component connected to the lamp body, and there are electrical components such as wires inside the lamp holder 21. The lamp holder 21 is also a part with a large amount of heat generation.

[0049] A heat insulation sleeve 6 is sleeved outside the lamp holder. The heat insulation sleeve 6 is made of silica gel or rubber. When personnel adjust the angle of the lamp, they can adjust it by pinching the lamp holder 21. By setting the heat insulation sleeve 6, it can prevent scalding when personnel touch the lamp holder 21.

[0050] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
