Description

Technical Field

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

[0002] Currently, mosquito coil heater products are generally divided into a main unit and a mosquito coil liquid bottle. The main unit and the mosquito coil liquid bottle are connected by threads. By holding the main unit with one hand and turning the mosquito coil liquid bottle with the other hand, the mosquito coil liquid bottle can be tightened or loosened.

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

[0004] Mosquito repellent liquid is slightly toxic. Children can easily unscrew the bottle, and if they accidentally drink it, it can cause poisoning. This poses a safety hazard to families with children. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings by providing a spinning structure and mosquito coil heater that makes it more difficult for children to open.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a spinning structure, disposed inside the main unit, comprising:

[0007] A cavity is provided on the host, and the interior of the cavity is provided with evenly distributed protrusions or grooves;

[0008] A swivel cap is movably disposed within the cavity, and the swivel cap is provided with a groove that matches the protrusion or a protrusion that matches the groove.

[0009] Furthermore, the cavity has evenly distributed undercuts on the side wall of the opening for limiting the position of the screw cap.

[0010] Furthermore, the distance between the buckle and the protrusion inside the cavity is greater than the height of the screw cap.

[0011] Furthermore, the spun cap includes a cylindrical body and a top cover disposed at one end of the cylindrical body, the groove is circumferentially disposed on the top cover, and the top cover is provided with a through hole.

[0012] Furthermore, the inner wall of the opening of the cylinder is provided with internal threads.

[0013] Furthermore, a blocking block is provided at one end of the internal thread near the top cover for blocking.

[0014] A mosquito coil heater includes the above-mentioned spinning structure, a main unit, and a mosquito coil liquid bottle threadedly connected to the spinning structure;

[0015] In the initial state, the opening of the cavity faces downwards, and the screw cap moves downwards under the action of gravity, disengaging the protrusion from the groove. At this time, the mosquito repellent liquid bottle drives the screw cap to rotate freely inside the cavity.

[0016] When in use, the opening of the cavity faces downwards, and the screw cap is pushed upwards. The protrusion and the groove cooperate, and the screw cap cannot rotate inside the cavity. At this time, rotating the mosquito repellent liquid bottle can disconnect the screw cap from the mosquito repellent liquid bottle.

[0017] Furthermore, the size of the through hole is larger than the core rod of the mosquito repellent liquid bottle.

[0018] Compared with the prior art, this utility model has the following beneficial effects:

[0019] This invention features a spinning structure inside the main unit. This spinning structure slides up and down within the unit's cavity. When the groove and protrusion are not properly aligned, rotating the mosquito repellent bottle will cause the spinning structure to spin freely. When the groove and protrusion are properly aligned, the spinning structure locks, allowing the mosquito repellent bottle to be released. Rotating the bottle will disconnect it from the spinning structure. The design of the groove and protrusion ensures that the bottle is always lifted during use to maintain the alignment, effectively preventing children from easily unscrewing it and eliminating the safety hazard of accidental ingestion by children.

[0026] 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.

[0027] Please see Figure 1-4 The spinning structure of this utility model is installed inside the main unit 1 and includes:

[0028] Cavity 2 is disposed on the host 1, and the interior of cavity 2 is provided with evenly distributed protrusions 21 or grooves 31;

[0029] The screw cap 3 is movably disposed within the cavity 2, and the screw cap 3 is provided with a groove 31 that matches the protrusion 21 or a protrusion 21 that matches the groove 31.

[0030] By moving the screw cap 3 up and down within the cavity 2, the posture of the screw structure can be adjusted as needed to engage or disengage the protrusion 21 and the groove 31. When the protrusion 21 and the groove 31 are engaged, the screw cap 3 is confined within the cavity 2 and cannot be rotated. When the protrusion 21 and the groove 31 are not engaged, the screw cap 3 can rotate freely within the cavity 2, preventing children from easily removing the mosquito repellent liquid bottle 4 when it is connected to the screw cap 3.

[0031] In one embodiment, the cavity 2 has evenly distributed inverted buckles 22 on its opening sidewall for limiting the screw cap 3. This design, by providing inverted buckles 22 on the opening sidewall of the cavity 2, can limit the screw cap 3 and prevent it from falling out of the cavity 2.

[0032] In one embodiment, the distance between the inverted buckle 22 and the protrusion 21 inside the cavity 2 is greater than the height of the screw cap 3. The distance between the inverted buckle 22 and the protrusion 21 is L, and the height of the screw cap 3 is h, where L > h. This design ensures that when the screw cap 3 is placed on the inverted buckle 22, there is a gap between the screw cap 3 and the protrusion 21, allowing the screw cap 3 to rotate normally without obstruction from the protrusion 21.

[0033] In one embodiment, the screw cap 3 includes a cylindrical body 32 and a top cap 33 disposed at one end of the cylindrical body 32. The groove 31 is circumferentially disposed on the top cap 33, and the top cap 33 is provided with a through hole 34. This design facilitates the engagement of the groove 31 with the protrusion 21 by placing the groove 31 on the top cap 33. Furthermore, when the screw cap 3 is placed on the inverted buckle 22, there is a gap between the groove 31 and the protrusion 21 on the top cap 33. The through hole 34 facilitates the placement of the mosquito repellent liquid bottle 4 core without affecting the normal use of the mosquito repellent liquid bottle 4.

[0034] In one embodiment, an internal thread 35 is provided on the inner sidewall of the opening of the cylinder 32. This design facilitates the installation of the mosquito repellent liquid bottle 4 by providing the internal thread 35.

[0035] In one embodiment, a blocking block 36 is provided at one end of the internal thread 35 near the top cover for blocking. This design can prevent the mosquito repellent liquid bottle 4 from continuing to rotate after installation, that is, to stop the rotation of the mosquito repellent liquid bottle 4 within the screw cap 3, avoiding damage to the screw cap 3 caused by continued rotation. While ensuring a stable connection between the mosquito repellent liquid bottle 4 and the screw cap 3, it also improves the service life of the screw cap 3.

[0036] A mosquito coil heater includes the above-mentioned spinning structure, a main unit 1, and a mosquito coil liquid bottle 4 threadedly connected to the spinning structure;

[0037] In the initial state, the opening of the cavity 2 faces downward, and the screw cap 3 moves downward under the action of gravity, and the protrusion 21 and the groove 31 are disengaged. At this time, the mosquito repellent liquid bottle 4 drives the screw cap 3 to rotate freely in the cavity 2.

[0038] In use, with the opening of the cavity 2 facing downwards, the screw cap 3 is pushed upwards, and the protrusion 21 engages with the groove 31, preventing the screw cap 3 from rotating inside the cavity 2. At this time, rotating the mosquito repellent liquid bottle 4 can disconnect the screw cap 3 from the mosquito repellent liquid bottle 4.

[0039] In one embodiment, the size of the through hole 34 is larger than the core of the mosquito repellent liquid bottle 4. This design does not affect the normal use of the mosquito repellent liquid bottle 4.

[0040] Preferably, in the tightening direction of the mosquito repellent liquid bottle 4, the sides where the groove 31 and the protrusion 21 abut against each other are both right-angled surfaces; in the loosening direction of the mosquito repellent liquid bottle 4, at least one side where the groove 31 and the protrusion 21 abut against each other is chamfered. This design enables stable positioning of the screw cap 3 when the mosquito repellent liquid bottle 4 is tightened, facilitating the tightening of the mosquito repellent liquid bottle 4. In the loosening direction of the mosquito repellent liquid bottle 4, the screw cap 3 needs to be continuously lifted to loosen the mosquito repellent liquid bottle 4, which is more difficult for children to operate, thus effectively preventing children from accidentally ingesting the mosquito repellent liquid bottle 4.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
