Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, and in particular to an anti-itch device. Background Technology

[0002] During peak mosquito season, people are more susceptible to mosquito bites. Mosquitoes typically carry large amounts of bacteria and viruses, which are left at the bite site after a bite, causing intense itching or infection. People often scratch the bite, further aggravating the infection. Furthermore, mosquitoes act as vectors for various diseases (such as dengue fever and malaria), posing a significant threat to human health.

[0003] With the advancement of technology, corresponding antibacterial and antipruritic products have emerged, including pharmaceutical and electronic products. Pharmaceutical products generally have certain side effects, or after a period of use, the body may develop drug resistance, rendering them ineffective in killing bacteria and relieving itching. Therefore, some electronic antipruritic devices have appeared on the market, which mainly use heating to relieve itching at the site of mosquito bites. However, the micro-switches of current antipruritic devices on the market are located on the side or back. When using them, the treatment head is usually aimed at the mosquito bite, and then the switch is pressed to relieve the itching. This usually requires the cooperation of two hands, and they are also relatively long and inconvenient to carry. Summary of the Invention

[0004] The purpose of this utility model is to overcome the defects of the prior art. This utility model provides an anti-itch device with the switch located inside the shell and triggered by the relative extension and retraction of the physiotherapy part. It is simple to operate and convenient to use. Furthermore, it eliminates the need to place the switch on the side wall and can further shorten the length of the shell, making it more convenient to carry.

[0005] This utility model discloses an antipruritic device, including a housing, on which a heating element, a circuit board, and a micro switch for controlling the operation of the heating element are provided. The housing includes a mounting part and a physiotherapy part that slides and guides on the mounting part. The micro switch is disposed between the mounting part and the physiotherapy part, and the physiotherapy part can extend and retract relative to the mounting part and squeeze the micro switch to realize the opening and closing of the micro switch.

[0006] Using the above technical solution, when in use, the physiotherapy part is pressed against the mosquito bite site. At this time, the physiotherapy part can slide relative to the mounting part, thereby squeezing the micro switch, causing the heating element to work and generate heat energy, thus achieving the effect of relieving itching. Furthermore, the micro switch is triggered by the relative extension and retraction of the physiotherapy part, which does not require the assistance of additional fingers, making it more convenient to use. In addition, the micro switch does not need to be placed on its side, which can also shorten the length of the shell.

[0007] A further feature of this invention is that the heating element is an infrared therapy lamp, the light-emitting end of which is oriented towards the therapy area, and several infrared therapy lamps are arranged along the circumference.

Detailed Implementation

[0020] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings: In the description of this utility model, it should be understood that the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right", etc., 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 device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] This utility model discloses an antipruritic device, including a housing 1. The housing 1 is provided with a heating element 2, a circuit board 3, and a micro switch 4 for controlling the operation of the heating element 2. In an embodiment of this utility model, the housing 1 includes a mounting part 11 and a physiotherapy part 12 that slides and is guided on the mounting part (the guiding and sliding of the physiotherapy part 12 can be a sliding guide with a reference sleeve, or a sliding guide with a guide rail and guide groove. The specific installation method is a common practice for those skilled in the art and will not be described in detail here). The micro switch 4 is disposed between the mounting part 11 and the physiotherapy part 12, and the physiotherapy part 12 can extend and retract relative to the mounting part 11 and squeeze the micro switch 4 to realize the opening and closing of the micro switch 4. Using this control method, the heating element 2 can be turned off after the physiotherapy part 12 is released from the squeeze, which can also save electricity.

[0022] Using the above technical solution, when in use, the physiotherapy part 12 is pressed against the mosquito bite site. At this time, the physiotherapy part 12 can slide relative to the mounting part 11, thereby pressing the micro switch 4, causing the heating element 2 to work, thereby generating heat energy, thus achieving the effect of relieving itching. Furthermore, the physiotherapy part 12 is used to trigger the micro switch 4 by relative extension and retraction, which does not require the assistance of additional fingers, making it more convenient to use. In addition, the micro switch 4 does not need to be sideways, which can shorten the length of the housing 1. The circuit board at the bottom of the micro switch 4 is usually relatively wide. If it is sideways and the button position is exposed on one side of the mounting part, then a relatively long space is required for its placement. Therefore, it is directly set between the physiotherapy part 12 and the mounting part 11, which is equivalent to a horizontal setting. Since the height L of the micro switch is smaller than its width H, the length can be reduced.

[0023] The heating element 2 is an infrared therapy lamp (of course, the heating element 2 can also be a heating wire, heating plate or heating lamp). The light-emitting end of the infrared therapy lamp is set towards the therapy section 12, and there are several infrared therapy lamps arranged in a circumferential direction. The heating effect of the infrared therapy lamp is relatively gentle, which further prevents burns to the user.

[0024] The trigger end of the micro switch 4 is positioned facing the mounting part 11 and abuts against the mounting part 11. The physiotherapy part 12 is also provided with a positioning block 121. The micro switch 4 is provided with a positioning groove 41 that is adapted to the positioning block 121. The positioning block 121 is inserted into the positioning groove 41. The heating element 2 is provided on the micro switch 4 and is located on the side facing the physiotherapy part 12. The trigger end z of the micro switch 4 has a certain elastic reset function. Through the abutting relationship, it can drive the physiotherapy part 12 to reset, thereby facilitating its reciprocating use. Furthermore, the cooperation between the positioning block 121 and the positioning groove 41 can prevent the micro switch 4 from shaking relative to each other, making it more stable during use. Of course, the physiotherapy part 12 can also use springs, spring sheets, or other reset components to assist in reset.

[0025] The head of the positioning block 121 is also provided with an inclined guide surface 1211, which makes it easy for the positioning block 121 to be inserted into the positioning groove 41.

[0026] The circuit board 3 is electrically connected to a power connector 5 (preferably a USB interface). By setting the power connector 5, it can be plugged into a mobile phone to draw power, or it can draw power from a compatible battery, thus eliminating the need to mount the battery on the casing 1 and further reducing the size.

[0027] The power connector 5 is located on the mounting part 11 and on the opposite side of the physiotherapy part 12, which facilitates the use of the product.

[0028] The mounting part 11 is also provided with a protective cover 6 at the position of the power plug 5. The protective cover 6 is also provided with a wire hole 61. The protective cover 6 can prevent the power plug 5 from being crushed and can also play a dustproof role. The wire hole 61 can facilitate the wire to be threaded and hung on the mobile phone or keychain.
