[0029] The following is combined with Figures 1-3This invention describes an antipruritic device, comprising a housing 1, a main control board 2, and a battery module 5. The housing 1 includes an upper shell component 10 and a lower shell component 11, which are snap-fitted together, forming an assembly space within the upper shell component 10 and the lower shell component 11. A positioning component 113 is provided within the assembly space. A battery compartment 112 and a positioning hole 114 are provided on the back of the lower shell component 11, with the positioning hole 114 located on one side of the battery compartment 112. The main control board 2 is positioned within the assembly space via the positioning component 113. A heating component 3 is provided at one end of the main control board 2 and is electrically connected to the main control board 2. The battery module 5 is located within the battery compartment 112 and on one side of the main control board 2, and is used to provide power to the main control board 2. The heating component 3 includes a heating plate 31 and a fixing plate 32. The heating plate 31 is fixed to the main control board 2 via the fixing plate 32, and the heating plate 31 is located within the positioning hole 114. Itch relief devices are typically portable handheld devices. When assembled using fasteners such as bolts, the assembly process is cumbersome due to the small size of the product and the low assembly accuracy. In this embodiment, the upper shell component 10 and the lower shell component 11 are connected by snap-fit, thereby achieving the connection of the shell 1. This method avoids the cumbersome process of connecting with bolts or glue, and the snap-fit method can ensure the accuracy of the assembly of the shell 1. Furthermore, the internal main control board 2 is fixed by positioning component 113. This method improves the overall assembly efficiency, allowing the main control board 2 to be assembled quickly and improving the assembly efficiency of the finished product.
[0030] Specifically, the upper shell component 10 and the lower shell component 11 are snapped together after being engaged. After snapping together, their internal spaces are connected to form an assembly space, which is mainly used for assembling the main control board 2. The battery module 5 is a storage battery, which is located in the battery compartment 112 and provides power to the main control board 2 to drive the heating component 3 to generate heat, thereby achieving heat therapy.
[0031] The battery compartment 112 is located on one side of the installation space, and the opening of the battery compartment 112 is located outside the assembly space. This method enables efficient use of space and makes the overall structure more compact.
[0032] In a specific configuration, the side of the lower shell component 11 and the upper shell component 10 away from each other is the back side, and the lower shell component 11 includes a first end and a second end. The front side near the first end of the lower shell component 11 has a receiving chamber 111, and the back side near the second end of the lower shell component 11 has a battery compartment 112. The receiving chamber 111 forms an assembly space after it is snapped into the upper shell component 10.
[0033] Furthermore, the positioning component 113 is disposed within the receiving cavity 111 of the lower shell component 11, so that after it mates with the upper shell component 10, it is located within the assembly space, thereby enabling the positioning of the main control board 2. It should be understood that after the main control board 2 is positioned by the positioning component 113, since the main control board 2 is located entirely within the installation space, and is relatively fixed by the limiting forces of the upper shell component 10 and the lower shell component 11, the cumbersome process of fixing with bolts or other fastening devices is avoided.
[0034] It is understandable that the antipruritic device itself has relatively few internal components. In this embodiment, the heating element 3 is connected to the end of the main control board 2, which simplifies the installation of internal components and improves the overall assembly efficiency. The entire assembly process requires the assembly of the housing 1 and the main control board 2. In this embodiment, the housing 1 is assembled using a snap-fit method, while the main control board 2 is installed in the assembly space via the connection of the positioning component 113. The overall assembly method is simple and the assembly efficiency is high.
[0035] like Figure 4 , Figure 5 As shown, in some embodiments, the upper shell component 10 has multiple slots 104 spaced apart along its edge, and the lower shell component 11 has multiple buckles 115 spaced apart along its edge. The multiple buckles 115 correspond one-to-one with the multiple slots 104. The cooperation between the multiple buckles 115 and the multiple slots 104 enables a stable fastening between the upper shell component 10 and the lower shell component 11, improving the stability of the shell 1 connection.
[0036] Understandably, multiple snap fasteners 115 are located on the edge of the lower shell component 11. This allows the upper shell component 10 and the lower shell component 11 to be stably connected, improving the stability of the shell 1's engagement. Furthermore, the multiple snap fasteners 115 are distributed around the edge of the lower shell component 11, resulting in a better overall engagement effect and higher stability of the shell 1.
[0037] For example, seven buckles 115 are evenly arranged around the edge of the lower shell component 11, and seven slots 104 are provided on the upper shell component 10. The seven slots 104 and the seven buckles 115 are set one-to-one, so as to achieve stable engagement.
[0038] Of course, in other embodiments, the lower shell component 11 has a plurality of slots 104 spaced apart along its edge, and the upper shell component 10 has a plurality of buckles 115 spaced apart along its edge, with each buckle 115 corresponding to a slot 104. That is, the buckles 115 can be provided on either the upper shell component 10 or the lower shell component 11, and correspondingly, the slots 104 can also be provided on either the lower shell component 11 or the upper shell component 10.
[0039] Of course, alternatively, the upper shell component 10 can be alternately and evenly provided with buckles 115 and slots 104, and correspondingly, the lower shell component 11 can be alternately and evenly provided with slots 104 and buckles 115 to achieve a snap-fit engagement between the two. It should be understood that the specific structure of the buckle 115 is a conventional buckle 115 structure, and those skilled in the art can easily obtain the buckle 115 structure after understanding the above solution; therefore, the specific mechanism will not be described in detail. For example, conventional fastening buckles 115, locking buckles 115, etc.
[0040] In some embodiments, the positioning component includes multiple limiting posts arranged in an array at intervals, forming a positioning space, within which the main control board 2 is located. The array of multiple limiting posts at intervals forms the positioning space, and the main control board 2 cooperates with the positioning space, enabling it to abut against the limiting posts and achieve positioning of the main control board 2.
[0041] Specifically, the main control board 2 is a PCBA board, which, by abutting against the limiting post, keeps the main hole plate within the positioning space from swinging, thus restricting the circumferential degree of freedom of the main control board 2 and achieving the positioning of the main control board 2.
[0042] In a specific configuration, limit slots are provided on both sides of the main control board 2. The limit slots are engaged with the limit posts to achieve stable positioning of the main control board 2 and ensure the stable assembly of the main control board 2.
[0043] For example, such as Figure 5 As shown, four limiting posts are provided on the lower shell component 11. The four limiting posts are arranged in a rectangular row. The limiting slots on the main control board 2 cooperate with the limiting posts, so that the limiting posts can be inserted into the limiting slots, thereby realizing the positioning of the main control board 2 and ensuring the stability of the assembly of the main control board 2.
[0044] According to the embodiments provided by this utility model, the heating component 3 further includes a light-shielding foam 33, which is disposed on the main control board 2 and located at the position of the heating component 3. The light-shielding foam 33 can play a shock-absorbing role for the main control board 2, preventing vibrations when the heating component 3 comes into contact with the human body from affecting the stability of the internal structure.
[0045] Understandably, during actual operation, the heating plate 31 is located within the positioning hole 114, and the heating surface of the heating plate 31 is flush with the outer surface of the lower shell component 11, or the heating surface of the heating plate 31 slightly protrudes from the outer surface of the lower shell component 11, thereby enabling better heat application. During the heat application process, a force is applied to the heating element 3, which is transmitted to one end of the main control board 2. The influence of this force is reduced by the light-shielding foam 33, thereby improving the overall service life.
[0046] In specific configuration, the light-shielding foam 33 is a single-sided adhesive EVA foam, which is bonded to the main control board 2. The main control board 2 has two sides. One side is connected to the heating element 3, with the heating plate 31 on the heating element 3 positioned within the positioning hole 114. The other side has other components, to which the light-shielding foam 33 is bonded. That is, the light-shielding foam 33 and the heating element 3 are located on the front and back sides of the main control board 2, respectively, thereby absorbing the force applied during heat therapy.
[0047] Specifically, the main component of single-sided adhesive EVA foam is ethylene-vinyl acetate copolymer (EVA), combining the softness of foam with the adhesive properties of the backing. The adhesive design allows the EVA foam to quickly and firmly adhere to various surfaces, reducing assembly and installation time. It also boasts strong adhesion, making it suitable for long-term fixed use and offering good durability. EVA foam has excellent cushioning properties, effectively absorbing impacts and vibrations to protect the main control board 2 from damage. Under stress, it can evenly distribute pressure, reducing the risk of localized damage. Furthermore, the lightweight nature of single-sided adhesive EVA foam makes it more convenient for transportation and application, reducing overall weight.
[0048] In some embodiments, a connection hole 101 is provided on the back of the upper shell component 10, and a button assembly 4 is provided in the connection hole 101. The button assembly 4 is electrically connected to the main control board 2. The button assembly 4 is used to control the itch relief device to turn on and off, and the setting of the button assembly 4 makes the operation of the itch relief device more convenient.
[0049] Understandably, the button assembly 4 can be pressed to control the opening and closing of the antipruritic device. Placing it on the upper shell component 10 facilitates the overall layout, making the overall structure more compact. Furthermore, the button assembly 4 can contact the main control board 2, thereby limiting the vertical movement of the main control board 2 and improving the stability of the main control board 2 installation.
[0050] In a further embodiment, the button assembly 4 includes a button part 41 and a gear indicator light 42. The gear indicator light 42 includes a cylindrical main body, the button part 41 is snapped into the main body, and the main body is snapped into the connection hole 101. The gear indicator light 42 is connected to the main control board 2, enabling the gear indicator light 42 to emit light of an indicative color, and the button part 41 can realize the opening and closing of the gear indicator.
[0051] In specific settings, a push-button switch 22 is provided on the main control board 2, and a button part 41 is located above the push-button switch 22. The button part 41 is made of transparent material, and the button part 41 can contact the push-button switch 22 when pressed, thereby realizing the opening and closing of the antipruritic device.
[0052] In some examples, a positioning post 103 is provided on the upper cover component near the connection hole 101, and a positioning hole 114 is provided on the main body of the position indicator light 42. The positioning hole 114 and the positioning post 103 cooperate to position the main body, so that the main body can be stably set on the upper shell component 10, thereby improving the stability of the connection.
[0053] In some embodiments, polarized spring contacts 6 are provided inside the side walls of the battery compartment 112, and the polarized spring contacts 6 are electrically connected to the main control board 2. The polarized spring contacts 6 are used to limit the storage battery, thereby limiting the battery's position and ensuring its conductivity.
[0054] In a specific configuration, there are positive and negative battery contacts. The positive battery contact is in contact with the positive terminal of the battery, and the negative battery contact is in contact with the negative terminal of the battery, thus forming a complete circuit.
[0055] In some embodiments, the heating plate 31 includes a ceramic heating plate. Ceramic materials have good thermal conductivity, enabling rapid and uniform heat distribution, avoiding hot and cold spots, and improving heating efficiency. It can reach the required temperature in a shorter time, improving the response speed of the itch relief device. Furthermore, ceramic heating plates have good corrosion resistance to many chemicals, and ceramic materials are generally non-toxic and do not release harmful substances, ensuring high safety. Furthermore, the surface of the ceramic heating plate is smooth, easy to clean, and does not easily accumulate dirt, maintaining good hygiene.
[0056] Specifically, in some embodiments, the antipruritic device also includes a long strip-shaped back cover 12. The two ends of the back cover 12 are provided with limiting buckles 121, corresponding to limiting grooves on the two opposite side walls of the battery compartment 112. The limiting buckles 121 engage with the limiting grooves to limit the movement. The back cover 12 allows the battery compartment 112 to be closed, preventing the battery from falling out and providing some dust protection.
[0057] Specifically, such as Figure 4 , Figure 5 As shown, the battery compartment 112 is located on the tail of the antipruritic device, and the heating element 3 is located on the head of the antipruritic device. The rear cover 12 is inserted into the tail of the antipruritic device and can completely cover the battery compartment 112 to protect the battery.
[0058] In some embodiments, a threading hole 102 is provided at one end of the upper shell component 10. The threading hole 102 is used to connect a hanging rope, thereby facilitating the carrying of the antipruritic device.
[0059] Through the above description of the embodiments, those skilled in the art can clearly understand that the antipruritic device is assembled by means of buckle 115 and positioning component 113 for limiting and fixing in each embodiment. The assembly method is simple, avoids the labor cost design required for glue application, screw fixing, etc., saves assembly time, and improves assembly efficiency.
[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
