Abstract

The utility model discloses a child lock of an electric heating liquid mosquito-repellent incense heater, which relates to the technical field of electric heating liquid mosquito-repellent incense and comprises a threaded ring and a support. A clamping point is arranged at the top of the threaded ring, when the clamping point makes contact with the side wall of the support, the support limits rotation of the threaded ring, and when the clamping point is separated from the support, the threaded ring freely rotates. According to the child lock of the electric mosquito liquid heater, the threaded ring can rotate relative to the base, so that when the liquid medicine bottle is directly rotated, the liquid medicine bottle cannot be separated from the threaded ring, the liquid medicine bottle needs to be pushed upwards with force, the clamping point on the threaded ring is clamped with the support, and the purpose of screwing up or screwing down the liquid medicine bottle is achieved. Due to the fact that the strength of the child is small, the liquid medicine bottle cannot abut against the support, the threaded ring rotates, and the liquid medicine bottle cannot be screwed up or screwed down. The children can be prevented from rotating out of the liquid medicine bottle to play, and the situation that the children are scalded by the core rod and even take toxic mosquito-repellent incense liquid mistakenly when the core rod is pulled out is avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of electric heating liquid mosquito-repellent incense, in particular to a child lock of an electric heating liquid mosquito-repellent incense heater. Background Art

[0002] The electric mosquito-repellent liquid heater comprises a heating element and a threaded ring. The mosquito-repellent liquid in the mosquito-repellent liquid bottle is evaporated by the heating element to achieve the effect of repelling mosquitoes by screwing the mosquito-repellent liquid bottle into the threaded ring.

[0003] Existing electric mosquito-repellent liquid heaters generally do not have a child lock structure, and the medicine bottle and the threaded seat are only connected by threads, so both adults and children can easily screw the medicine bottle on or off. When children come into contact with the electric mosquito-repellent liquid heater, they are likely to play with the heater, which will unscrew the medicine bottle, and the medicine bottle will have an adverse effect on children. Especially when the electric mosquito-repellent liquid heater is in working state, the heater is taken down. At this time, the core rod on the medicine bottle is still at high temperature, which can easily cause scalds to children. In extreme cases, it may even cause the core rod to be pulled out and the toxic mosquito-repellent liquid to be accidentally ingested. Therefore, the traditional electric mosquito-repellent liquid heater does not have a child lock structure, which will have certain safety hazards. Summary of the invention

[0004] The utility model aims to provide a child lock for an electric mosquito-repellent liquid heater to solve the problems existing in the above-mentioned prior art. A child lock structure is added to the electric mosquito-repellent liquid heater to improve the safety of the electric mosquito-repellent liquid heater without affecting the basic functions of the electric mosquito-repellent liquid heater.

[0005] To achieve the above purpose, the utility model provides the following solutions:

[0006] The utility model provides a child lock for an electric mosquito-repellent liquid heater, comprising a threaded ring and a bracket; the bracket is arranged at the bottom of a heating element, and the bracket is connected to the base; the threaded ring is a hollow cylindrical structure, and an internal thread is arranged on the inner wall of the threaded ring, and the internal thread is used to be connected to a medicine bottle; the threaded ring is slidably arranged in the base, and the threaded ring is located directly below the bracket; a card point is arranged on the top of the threaded ring, and when the card point contacts the side wall of the bracket, the bracket limits the rotation of the threaded ring, and when the card point is separated from the bracket, the threaded ring rotates freely.

[0007] Optionally, the clamping point is a block-shaped protrusion at the top of the thread ring.

[0008] Optionally, the top of the clamping point and the top of the thread circle are transitioned by a smooth curve.

[0009] Optionally, the jamming points are a plurality of arc-shaped blocks protruding upward from the top edge of the thread ring, and the interval between adjacent arc-shaped blocks is greater than the width of the bracket.

[0010] Optionally, in the direction in which the medicine bottle is screwed into the thread ring, the height of the arc-shaped block is higher, and in the direction in which the medicine bottle is screwed out of the thread ring, the height of the arc-shaped block is lower.

[0011] Optionally, a face cover is provided above the base.

[0012] Optionally, the face cover and the base are connected by screws, ultrasonic welding, thermal riveting, snap connection or bonding connection.

[0013] Optionally, a vertical ventilation hole is provided in the middle of the face cover, and the ventilation hole is coaxially arranged with the thread ring.

[0016] The present utility model has achieved the following technical effects compared with the prior art:

[0017] The child lock of the electric heating mosquito-repellent liquid heater of the present utility model has a thread ring that can rotate relative to the base. Thus, when directly rotating the medicine bottle, the medicine bottle cannot be separated from the thread ring, and it is necessary to forcefully push the medicine bottle upward so that the jamming points on the thread ring are stuck with the bracket, thereby achieving the purpose of screwing the medicine bottle on or off. Since children have relatively little strength and cannot hold the medicine bottle against the bracket, the thread ring will rotate, and the medicine bottle cannot be screwed on or off. The child lock of the electric heating mosquito-repellent liquid heater of the present utility model is more friendly to children, can prevent children from unscrewing the medicine bottle for play, avoid the core rod scalding children, and even prevent the core rod from being pulled out and the poisonous mosquito-repellent liquid from being accidentally taken.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0027] The purpose of the present utility model is to provide a child lock for an electric mosquito-repellent liquid heater to solve the problems existing in the prior art. On the basis of the electric mosquito-repellent liquid heater, a child lock structure is added to improve the safety of the electric mosquito-repellent liquid heater without affecting its basic functions.

[0028] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0029] Embodiment 1:

[0030] As Figures 1 to 4As shown in the figure, the present embodiment provides a child lock for an electric mosquito repellent liquid heater, which includes a threaded ring 3 and a bracket 21; the bracket 21 is arranged at the bottom of the heating element 2, and the bracket 21 is connected to the base 5; the threaded ring 3 is a hollow cylinder structure, and internal threads are provided on the inner wall of the threaded ring 3 for connecting with the medicine bottle 6; the threaded ring 3 is slidably arranged in the base 5 and is located directly below the bracket 21; a clamping point 31 is arranged at the top of the threaded ring 3. When the clamping point 31 contacts the side wall of the bracket 21, the bracket 21 restricts the rotation of the threaded ring 3. When the clamping point 31 is separated from the bracket 21, the threaded ring 3 rotates freely.

[0031] In this specific embodiment, a through mounting hole is arranged in the middle of the base 5. A limiting ring in the axial direction is formed by extending a certain dimension radially outward at the top of the threaded ring 3. The outer diameter of the threaded ring 3 is smaller than the inner diameter of the mounting hole, but the outer diameter of the limiting ring is larger than the inner diameter of the mounting hole. Thus, the threaded ring 3 can move up and down axially in the base 5 without falling off.

[0032] The clamping point 31 is a protrusion at the top of the threaded ring 3. The protrusion can be a columnar protrusion with a side wall perpendicular to the end face. The height or shape of the protrusion can be set according to the actual situation. The larger the height of the protrusion, the easier it is for the clamping point 31 to be blocked by the bracket 21, and the easier it is to disassemble the medicine bottle. On the contrary, the smaller the height of the protrusion, the more difficult it is for the clamping point 31 to be blocked by the bracket 21, and a greater force is required to lift the medicine bottle upward when disassembling the medicine bottle, and the disassembly difficulty is greater. In this specific embodiment, the top of the clamping point 31 and the top of the threaded ring 3 are transitioned by a smooth curve, and its shape is similar to the head of a tank. This shape requires applying a relatively large pressure to the medicine bottle to form a limit between the threaded ring 3 and the bracket 21 through the clamping point 31, but the required space is small.

[0033] The bracket 21 is a rectangular structure. The two ends of the bracket 21 are respectively connected to the base 5. A through hole is arranged in the middle of the bracket 21 for passing through the core rod in the medicine bottle 6.

[0034] In a more specific embodiment, a face cover 1 is arranged above the base 5. The face cover 1 and the base 5 are connected by screws. A vertical ventilation hole is arranged in the middle of the face cover 1, and the ventilation hole is coaxially arranged with the threaded ring 3. A plug socket 4 is arranged on one side of the base 5. The plug socket 4 is used for electrically connecting with the mains power supply, and the plug socket 4 is electrically connected to the heating element 2.

[0035] Embodiment Two:

[0036] As Figure 5 shown in the figure, in this embodiment, four arc-shaped blocks protruding upward from the top edge of the threaded ring, and the interval between adjacent arc-shaped blocks is greater than the width of the bracket. The bracket is stuck between adjacent arc-shaped blocks to prevent the threaded ring from rotating, thereby realizing screwing the medicine bottle into or out of the threaded ring.

[0037] In a more specific embodiment, in the direction in which the medicine bottle is screwed into the thread ring, the height of the arc-shaped block is relatively high, and in the direction in which the medicine bottle is screwed out of the thread ring, the height of the arc-shaped block is relatively low. When the medicine bottle is screwed into the thread ring, a relatively small force applied to the medicine bottle can make the bracket get stuck between adjacent arc-shaped blocks, facilitating the installation of the medicine bottle. When the medicine bottle is screwed out of the thread ring, a relatively large force needs to be applied to the medicine bottle to make the bracket get stuck between adjacent arc-shaped blocks. Since children have relatively little strength, they will not be able to screw out the medicine bottle. Thus, it is both convenient for the installation of the medicine bottle and can provide good protection for children.

[0038] When no external force is applied, the interval between the top of the arc-shaped block and the bottom of the bracket is relatively small, and the thread ring has better stability, preventing the thread ring from being too loose.

[0039] It should be noted that for those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model, and any reference signs in the claims should not be regarded as limiting the claims involved.

[0040] In this specification, specific examples are used to illustrate the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
