Description

Technical Field

[0001] This utility model relates to the field of plug mounting structure technology, specifically to a plug mounting structure and a mosquito coil heater. Background Technology

[0002] Currently, most mosquito coil heater products have power plugs designed to rotate 90 degrees to accommodate commonly used vertical and horizontal sockets for user convenience. The plug is typically secured to the main unit by splitting the casing into upper and lower parts.

[0003] The products mentioned above have the following shortcomings:

[0004] The above structure is simple and easy to assemble, but the product's appearance is greatly affected. Due to structural limitations, the product's appearance is forcibly divided into several sections, resulting in more seams and an unsightly appearance. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a plug installation structure and mosquito coil heater with an aesthetically pleasing appearance and fewer seams.

[0006] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a plug mounting structure, disposed on a housing, wherein a base is detachably disposed inside the housing, comprising:

[0007] Mounting holes are provided on the side wall of the housing for the plug to pass through;

[0008] The first rib is provided on the inner sidewall of the outer casing and located below the mounting hole, and a first gap is provided between it and the inner sidewall of the outer casing.

[0009] A step is provided at the tail of the plug. The step has a notch with an angle greater than that of the first rib, and the thickness of the step is less than the width of the first gap.

[0010] Furthermore, a second rib corresponding to the first rib is provided on the base above the mounting hole, and a second gap for allowing the step to rotate is provided between the second rib and the outer shell.

[0011] Furthermore, the step is provided with a first convex bulge and a second convex bulge on the inner sides of both sides of the notch, and two symmetrically distributed first baffles are provided on the second rib to block the first convex bulge and the second convex bulge.

[0012] Furthermore, a positioning plate is provided between the two first baffles, and a slot is provided between the first baffles and the positioning plate for blocking the first convex bulge or the second convex bulge.

[0013] Furthermore, the two sides of the first convex hull and the second convex hull are respectively set as arc-shaped structures.

[0014] Furthermore, the base is provided with two spaced-apart second baffles, which are used to block the steps;

[0015] When the first protrusion rotates into one of the slots, the two prongs of the plug are vertical, and one of the second baffles blocks one side of the notch of the step, preventing the plug from continuing to rotate;

[0016] When the second protrusion rotates into another slot, the two prongs of the plug are horizontal, and the other side of the notch of the second stop block the step.

[0017] Furthermore, the angle of the first rib is less than 90°, and the angle of the notch is greater than 90°.

[0018] A mosquito coil heater includes the aforementioned plug mounting structure and a mosquito coil liquid bottle detachably disposed within the base.

[0019] Compared with the prior art, this utility model has the following beneficial effects:

[0020] 1. This utility model solves the problem of the prior art that requires the shell to be split into two parts by opening a mounting hole on the side wall of the shell for the plug to pass through, and the shell is integrally formed. The splicing seam is smaller and the product has a beautiful appearance.

[0021] 2. This utility model provides a first rib and a first gap with a width greater than the thickness of the step between the first rib and the inner wall of the outer shell. This allows the step to rotate easily within the first gap. Furthermore, the cooperation between the first rib and the outer shell helps to limit the movement of the step and prevents the plug from easily falling out of the mounting hole.

[0022] 3. This utility model provides a second rib on the base. After the plug is installed, the base is installed. The second rib, together with the first rib, can limit the upper and lower parts of the step, ensuring that the plug will not fall off after installation.

[0023] 4. By setting a first convex bulge and a second convex bulge, and by setting a first stop rib and a second stop rib in cooperation, this utility model can limit the plug when it is rotated to a horizontal state and a vertical state, which facilitates the use of the plug after the angle is adjusted.

[0034] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. 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.

[0035] Please see Figure 1-8 .

[0036] This utility model relates to a plug mounting structure, which is mounted on a housing 1, and a base 2 is detachably mounted inside the housing 1, comprising:

[0037] Mounting hole 11 is provided on the side wall of housing 1 for plug 3 to pass through;

[0038] The first rib 12 is disposed on the inner side wall of the outer shell 1 and located below the mounting hole 11, and a first gap 13 is provided between it and the inner side wall of the outer shell 1.

[0039] A step 31 is provided at the tail of the plug 3. The step 31 has a notch 32 with an angle greater than that of the first rib 12, and the thickness of the step 31 is less than the width of the first gap 13.

[0040] By opening a mounting hole 11 on the side wall of the outer shell 1, the plug 3 passes through the mounting hole 11 and is set on the outer shell 1. Then, the plug 3 is rotated until the notch 32 faces the base. At this time, the step 31 is located inside the first gap 13. This solves the defect of the outer shell 1 being set as two pieces in the prior art. There are fewer splicing seams and the product looks beautiful. The notch 32 on the step 31 has an angle greater than that of the first rib 12, which makes it easy for the plug 3 to be inserted into the mounting hole 11. Moreover, the thickness of the step 31 is less than the width of the first gap 13. After the plug 3 is inserted, the angle of the plug 3 can be adjusted by rotating it as needed. At this time, the first rib 12, together with the inner side wall of the outer shell 1, can limit the step 31, ensuring that the plug 3 will not easily fall off after installation.

[0041] In one embodiment, a second rib 21 corresponding to the first rib 12 is provided on the base 2 above the mounting hole 11, and a second gap 22 for allowing the step 31 to rotate is provided between the second rib 21 and the outer shell 1. With this design, after the plug 3 is installed in the mounting hole 11, the base 2 is installed inside the outer shell 1. By providing the second rib 21 on the base 2, in conjunction with the first rib 12, the step 31 on the plug 3 can be effectively limited, thereby preventing the plug 3 from falling out of the mounting hole 11 after installation.

[0042] In one embodiment, the step 31 has a first protrusion 33 and a second protrusion 34 respectively provided on the inner sides of both sides of the notch 32. The second rib 21 has two symmetrically distributed first baffles 23 for blocking the first protrusions 33 and 34. This design, by providing the first protrusions 33 and 34 on both sides of the notch 32 and the two symmetrically distributed first baffles 23, creates a rhythmic effect when the first protrusions 33 and 34 rotate past the first baffles 23. At this point, the user can clearly understand that the rotation has reached the correct position and no further rotation is needed; the plug 3 is then in a horizontal or vertical position.

[0043] In one embodiment, a positioning plate 24 is provided between the two first baffles 23, and a slot 25 for blocking the first protrusion 33 or the second protrusion 34 is provided between the first baffles 23 and the positioning plate 24. This design, by providing the positioning plate 24, can cooperate with the first baffles 23 on both sides to form two slots 25 for blocking the first protrusion 33 and the second protrusion 34 respectively. Thus, after the first protrusion 33 or the second protrusion 34 rotates past the first baffle 23, the positioning plate 24 and the first baffle 23 effectively limit the movement of the first protrusion 33 or the second protrusion 34, thereby preventing the plug 3 from easily rotating after angle adjustment and ensuring stability after angle adjustment.

[0044] In one embodiment, the two sides of the first convex 33 and the second convex 34 are respectively configured as arc-shaped structures. This design, by configuring the two sides of the first convex 33 and the second convex 34 as arc-shaped structures, facilitates the rotation of the first convex 33 and the second convex 34 into or out of the slot 25.

[0045] In one embodiment, the base 2 is provided with two spaced-apart second baffles 26, which are used to block the step 31;

[0046] When the first protrusion 33 rotates into one of the slots 25, the two prongs of the plug 3 are vertical, and one of the second baffles 26 blocks one side of the notch 32 of the step 31, preventing the plug 3 from continuing to rotate;

[0047] When the second protrusion 34 rotates into the other slot 25, the two prongs of the plug 3 are horizontal, and the other second baffle 26 blocks the other side of the notch 32 on the step 31. This design, by setting the second baffle 26, can block both sides of the notch 32 on the step 31, preventing the plug 3 from continuing to rotate after the angle is adjusted. Furthermore, through the cooperation of the first protrusion 33 or the second protrusion 34 with the slot 25, the plug 3 can be effectively positioned, ensuring the stability of the plug 3 after angle adjustment.

[0048] In one embodiment, the angle of the first rib 12 is less than 90°, and the angle of the notch 32 is greater than 90°. This design, where the angle of the notch 32 is greater than the angle of the first rib 12, facilitates the installation of the plug 3.

[0049] A mosquito coil heater includes the aforementioned plug mounting structure and a mosquito coil liquid bottle detachably disposed within the base 2.
