Description

Technical Field

[0001] This utility model patent relates to the field of antipruritic device technology, and in particular to a split-type antipruritic device. Background Technology

[0002] Many insect bites cause itching and even swelling at the bite site. The toxins that cause itching and swelling are usually composed of protein molecules. When the temperature exceeds a certain limit, the structure of these protein molecules changes, causing them to lose their activity. This relieves the itching, improves other symptoms, and promotes faster healing of the bite. Applying heat to the insect bite site is a very effective way to relieve insect bites and stings. An anti-itch device is a device that uses heat to relieve itching at the insect bite site.

[0003] Existing anti-itch devices typically use piezoelectric ceramic sheets as the contact medium between the device and the skin, and these sheets are integrated into the device design. The area of ​​the piezoelectric ceramic sheet is fixed for each device. However, mosquito bites vary in size, and the required heat application area differs for adults and children. If the bite is large, the device needs to heat different areas separately, which is inefficient. If the bite is small or located on a thin area like a finger, the device may not fit tightly, wasting power and reducing battery life. Therefore, fixed-size piezoelectric ceramic sheets cannot meet diverse user needs. Furthermore, piezoelectric ceramic sheets are easily damaged due to their physical properties; therefore, finding a convenient and quick replacement method is a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0004] This invention provides a split-type anti-itch device to solve the defects of existing anti-itch devices, such as fixed anti-itch area, inability to meet different user needs, and difficulty in replacing damaged piezoelectric ceramic plates.

[0005] A split-type antipruritic device comprises an antipruritic device main unit and a heating component pluggably connected thereto. The antipruritic device main unit includes an upper shell and a lower shell that overlap each other, forming a receiving space. A control board detachably fixed to the lower shell is disposed inside the receiving space. The heating component includes a heating component housing, a heating part fixed to one end of the heating component, and a heating plate electrically connected to the heating part for controlling the heating of the heating part. One end of the heating plate extends outside the heating component and can be inserted into the antipruritic device main unit, realizing the pluggable connection between the antipruritic device main unit and the heating component, while simultaneously being electrically connected to the control board, receiving control signals from the control board, and controlling the heating part to heat up.

[0006] Furthermore, the heating component is also provided with a sealing part fixedly connected to one end of the housing, for sealing one end of the heating component housing.

[0007] Furthermore, the sealing part is also provided with a fourth opening for one end of the heating plate to pass through, and a sealing ring can be fitted on the fourth opening to improve the waterproof capability.

[0008] Furthermore, a second opening is provided at one end of the upper shell, through which one end of the heating plate passes and is inserted into the main unit of the antipruritic device.

[0009] Furthermore, a support portion for improving the stability of the plug-in connection and fixing the connection is also provided on the inner side of the second opening.

[0010] Furthermore, the support is made of an elastic material, and the two are in an interference fit when one end of the heating plate passes through the support.

[0011] Furthermore, a magnetic attraction device is provided adjacent to the main unit of the antipruritic device and the heating component, serving as an auxiliary connection method for plug-in connection and further fixing function.

[0012] Furthermore, the heating element is composed of a piezoelectric ceramic sheet and a back plate that are attached and fixed to each other. The piezoelectric ceramic sheet protrudes from the back plate, and its protrusion height is less than 2mm.

[0013] Furthermore, the main unit of the antipruritic device is also equipped with a battery, which is located in the cutout of the control board. The battery is electrically connected to the control board and supplies power to the control board.

[0014] Furthermore, the main unit of the aforementioned split-type antipruritic device can be equipped with multiple heating components, each with a different effective heating area, ranging from 50 to 320 mm². 2 .

[0015] Compared with existing technologies, the above-mentioned split-type antipruritic device has the advantages of allowing users to change the size of the antipruritic area according to their needs, and facilitating the replacement and maintenance of the heating component.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "inner", "outer", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0029] like Figure 1-6As shown, this utility model provides an anti-itch device 100 with a variable anti-itch area. The main unit 110 of the anti-itch device includes an upper shell 111 and a lower shell 112 that overlap each other. The upper shell 111 and the lower shell 112 are fitted together to form a receiving space, within which a control board 113 is disposed. The control board 113 is detachably fixed inside the lower shell 112. Furthermore, the anti-itch device 100 also includes a heating component 120 that is pluggably connected to one end of the main unit 110.

[0030] like Figure 2 As shown, the heating assembly 120 includes a heating assembly housing 121, which is a hollow tubular shape. The heating assembly 120 also includes a heating section 123 and a heating plate 124 electrically connected to one end of the heating section 123. The heating section 123 consists of a piezoelectric ceramic sheet 1231 and a back plate 1232 that are attached and fixed to each other. The piezoelectric ceramic sheet 1231 protrudes from the back plate 1232, with a protrusion height of less than 2mm. During installation, the back plate 1232 is fixedly connected to the heating assembly housing 121, flush with the left end face of the heating assembly 120. At this time, the piezoelectric ceramic sheet 1231 slightly protrudes from the left end face of the heating assembly 120, allowing for better contact between the piezoelectric ceramic sheet and the mosquito bite during user use. The heating plate fixing end 1241 of the heating plate 124 is located near the left side of the heating assembly and is electrically connected to the heating section 123 via a wire. The heating plate insertion end 1242 of the heating plate 124 extends out of the heating assembly 120, is inserted into the main unit 110 of the antipruritic device, and is electrically connected to the control board 113. A conductive sheet is provided on the lower side of the heating plate insertion end 1242. After being inserted into the main unit 120 of the antipruritic device, the conductive sheet contacts the conductive contacts provided on the control board 113 to achieve electrical connection.

[0031] Furthermore, a fixing part 122 is also provided on the inner side of the heating component housing 121. The number of fixing parts 122 is generally even, and they are symmetrically distributed on the inner side of the heating component housing 121 to fix the heating plate 124.

[0032] Furthermore, the heating assembly 120 also includes a sealing portion 125. The sealing portion 125 is fixedly connected to the right side of the heating assembly housing 121, and after installation, it is flush with the right end face of the heating assembly 120, used to seal the right side of the heating assembly housing 121. The sealing portion 125 also has a fourth opening 1251 for the heating plate insertion end 1242 to pass through. The shape of the fourth opening 1251 is the same as the cross-sectional shape of the heating plate insertion end 1242 passing through it. Furthermore, a sealing ring is fitted onto the fourth opening 1251 to improve waterproofing.

[0033] Furthermore, a second opening 1113 is provided at the right end of the upper shell 111. The shape of the second opening 1113 is the same as the shape of the cross-section of the heating plate insertion end 1242 passing through it. When the heating assembly 120 is inserted into the antipruritic device host 110, the heating plate insertion end 1242 is inserted into the antipruritic device host 110 through the second opening 1113. To further improve the stability of the insertion and removal connection, a fixed connection support part 117 is also provided inside the second opening 1113. The support part 117 is a through-tube structure, the shape of which is the same as the shape of the second opening 1113. The support part 117 is made of elastic material, and when the heating plate insertion end 1242 passes through the support part 117, the two are in an interference fit.

[0034] Furthermore, the control board 113 is provided with a connector 1132. When the heating component 120 is inserted into the main unit 110 of the antipruritic device, the conductive sheet provided on the lower side of the heating plate insertion end 1242 of the heating component 120 contacts the conductive contact provided on the connector 1132 to achieve electrical connection. At the same time, the connector 1132 can also provide a certain degree of support for the heating plate 124 in the vertical direction.

[0035] Furthermore, when the antipruritic device main unit 110 and the heating component 120 are plugged and unplugged together, the right end face of the heating component 120 and the left end face of the antipruritic device main unit 110 are tightly fitted together. To increase the stability of the connection between the antipruritic device main unit 110 and the heating component 120, a magnetic attraction device is also provided on the right end face of the heating component and the left end face of the antipruritic device. The magnetic attraction connection serves as an auxiliary connection method for the plug-and-unplug connection, further securing the antipruritic device main unit 110 and the heating component 120.

[0036] Furthermore, the upper shell 111 of the anti-itch device host is provided with a first opening 1112. The button 114 passes through the first opening 1112 from the inside of the upper shell 111 and is flush with the upper surface of the upper shell 111. The protrusion on the lower side of the button 114 corresponds to the position of the button module on the control board 113. A light guide column 1111 is also provided on the inner side of the upper shell 111 of the anti-itch device. An indicator light cover 115 made of light-transmitting material is provided at the upper end of the light guide column 1111. The lower end of the light guide column 1111 abuts against the control board 113, and an LED light is provided at the corresponding projection position of the light guide column 1111 on the control board 113. When the anti-itch device is working, the LED light can switch on and off according to the working status of the device. Furthermore, several LED lights can be provided, and they can be different colors. At this time, different operating statuses of the device can be displayed by changing colors and light patterns, which serves as a reminder to the user. For example, the normal working state of the anti-itch device is indicated by a solid green light, the standby state by a solid white light, the charging state by a flashing white light, the low battery state by a flashing red light, and the abnormal state of the anti-itch device by a solid red light.

[0037] Furthermore, the main unit of the antipruritic device also houses a battery 116 for powering the antipruritic device 100. Furthermore, the battery 116 is a rechargeable battery. The lower shell 112 has a third opening 1121 for the charging interface to pass through. Furthermore, the battery 116 is positioned in a cutout on the control plate 113, which, together with the upper shell 111 and the lower shell 112, serves to limit the position of the battery 116.

[0038] like Figure 6 As shown, a single anti-itch device main unit 110 can be configured with multiple heating components 120. The difference between the multiple heating components 120 lies in their different effective heating areas. Further, this can be understood as the piezoelectric ceramic sheets 1231 having different sizes. The maximum size of the piezoelectric ceramic sheet 1231 should be smaller than the size of the back plate 1232. Considering the portability and battery life of the anti-itch device, the effective heating area of ​​the heating component 120 should not be too large, preferably 50-320 mm². 2 The shape of the piezoelectric ceramic sheet is not further limited here; the piezoelectric ceramic sheet 1231 can be of any shape, such as circular, square, cross-shaped, polygonal, etc. For example, in one embodiment, the piezoelectric ceramic sheet 1231 can be circular, with a radius of 4-10 mm. In another embodiment, the piezoelectric ceramic sheet can be square, with a long side of 8-20 mm and a short side of 7-15 mm. By setting different sizes of the piezoelectric ceramic sheet 1231, the itch-relieving area of ​​the itch-relieving device can be adjusted. When using it, the user can select the appropriate size heating component of the itch-relieving device according to the size of the mosquito bite. For example, a main unit 100 of the itch-relieving device can be equipped with three heating components 120, and the piezoelectric ceramic sheets of the heating components 120 are circular with radii of 4 mm, 6 mm, and 8 mm, respectively. If the mosquito bite area is large, an 8mm heating element can be installed. If the mosquito bite area is small, or if the bite is on a thin part such as a finger, a 4mm heating element can be used. In this case, simply pull out the 8mm heating element and insert the 4mm heating element to replace it. Furthermore, due to the physical properties of the material, the piezoelectric ceramic sheet 1231 is easily damaged when squeezed or bumped. As the heating element 120 is connected to the main unit 110 of the antipruritic device via a plug-in method, if the piezoelectric ceramic sheet is damaged, only a new heating element needs to be replaced, which greatly saves on the subsequent maintenance costs of the equipment.

[0039] The above embodiments are only for illustrating the technical concept of this utility model and should not be used to limit the protection scope of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the protection scope of this utility model.
