Description
Technical Field
[0001] This utility model belongs to the technical field of mosquito coil electric heaters, specifically relating to a mosquito coil electric heater with a push-push structure and associated switch. Background Technology
[0002] Electric mosquito repellent heaters are mosquito-repelling tools that work by using electric heating to evaporate the insecticide in the mosquito coil, thus repelling mosquitoes. Electric mosquito repellent heaters are popular in households due to their convenience, safety, and hygiene. Currently, mosquito coil heaters use a simple plug-in structure to hold the mosquito coil. During use, users need to manually insert the mosquito coil into the heating slot and then manually remove it afterward. While the plug-in structure is convenient for inserting the mosquito coil, removing it is very inconvenient because the exposed end of the coil is short. Furthermore, in existing technology, users must manually turn on the power switch or plug the coil into a power outlet after inserting it, and then manually turn it off or unplug it after removing it. Otherwise, it may result in no-load heating, posing a safety hazard and wasting energy. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a mosquito coil electric heater, which solves the technical problems in the background art mentioned above.
[0004] The purpose of this utility model is achieved as follows: A mosquito coil electric heater includes: a housing with a slot for accommodating a mosquito coil; a push-push mechanism including: a sliding component movably disposed within the housing, which can reciprocate when pushed by the mosquito coil; an elastic reset element connected to the sliding component; and a locking component that cooperates with the sliding component. During the movement of the sliding component and the locking component towards or away from each other, the locking or unlocking is switched through their cooperative structure. By providing a push-push mechanism corresponding to the slot in the housing, when the user needs to remove the mosquito coil, they press the mosquito coil back into the slot, and the push-push mechanism will pop the tail of the mosquito coil outwards, facilitating removal.
[0005] The working principle is as follows: When the mosquito coil is inserted into the slot, the coil moves the sliding component. This movement causes the elastic reset element to tensile and store energy. The locking component moves in the opposite direction to the sliding component, thus locking the mosquito coil. When the mosquito coil needs to be removed, pressing it a second time causes the coil to move the sliding component again. The elastic reset element releases its tension, and the sliding component returns to its initial state (the state when the mosquito coil is not inserted). At the same time, the tail of the mosquito coil is pushed outwards for easy removal by the user.
[0006] Furthermore, the sliding assembly includes a sliding block slidably connected to the guide rail. The upper surface of the sliding block is provided with a circulating groove. The circulating groove contains an entry track and an exit track. A locking protrusion and a guiding protrusion are fixedly provided inside the circulating groove, with the guiding protrusion corresponding to the locking protrusion. The locking protrusion has a locking groove, and the exit track has an inclined surface. The left end of the inclined surface is flush with the locking groove, and the right end is higher than the entry track. The sliding block has a pushing part for bearing the pushing force of the mosquito coil, and the pushing part has a mating groove. The Push-Push mechanism includes a tray fixedly disposed inside the box body. The sliding assembly, elastic reset element, and locking assembly are all disposed on the upper surface of the tray. The elastic reset element is a spring, one end of which is fixedly connected to the side wall of the tray, and the other end of which is fixedly connected to the side wall of the sliding block. The locking assembly includes a locking rod with bent portions at both ends. One bent portion of the locking rod is rotatably connected to the bottom surface of a triangular groove formed on the side wall of the support plate, while the other bent portion of the locking rod is slidably engaged with the uterine entry track. The inclined surface effectively prevents the locking rod from accidentally entering the uterine exit track during the relative movement of the locking rod and the sliding block.
[0007] During use, as the mosquito coil is inserted into the slot, the inner end of the low-pressure sliding block of the mosquito coil moves inward through its mating groove. During this movement, the spring is stretched, causing the locking rod to move in the opposite direction of the sliding block. The bent part of the locking rod moves along the uterine inlet track into the uterine cavity, and finally, the bent part of the locking rod is engaged inside the locking protrusion, thus securing the mosquito coil. When the mosquito coil is pressed again, the bent part of the locking rod separates from the locking protrusion. Simultaneously, under the action of the guide protrusion, the locking rod is guided to the outlet track. At this point, under the restoring force of the spring, the sliding block moves outward, causing the mosquito coil to pop outward.
[0008] Furthermore, the system also includes a switching mechanism linked to the Push-Push mechanism. When the Push-Push mechanism moves to the locked position in response to the insertion of the mosquito coil, it triggers the switching mechanism to conduct, energizing the heating element of the electric heater. When the Push-Push mechanism moves to the released position in response to a re-pressing action, it triggers the switching mechanism to disengage, de-energizing the heating element. The switching mechanism employs a photoelectric switch or a micro switch, eliminating the need for users to manually turn on the power switch or plug it into a power outlet after inserting the mosquito coil, and also eliminating the need to manually turn off the power switch or unplug it after removal, thus avoiding energy waste caused by no-load heating and improving safety.
[0009] The beneficial effects of this utility model are as follows: By setting a Push-Push mechanism corresponding to the slot in the box, when the mosquito coil needs to be pulled out, the user presses the mosquito coil back into the slot, and the Push-Push mechanism will pop the tail of the mosquito coil outward for easy removal. The working principle is as follows: When the mosquito coil is inserted into the slot, the inner end of the mosquito coil presses against the mating groove of the sliding block, causing the sliding block to move inward. During the movement of the sliding block, the spring is stretched, and the locking rod moves towards the sliding block. The bent part of the locking rod moves along the uterine track into the uterine cavity, and finally, the bent part of the locking rod is engaged inside the locking protrusion, thus fixing the mosquito coil. When the mosquito coil is pressed again, the bent part of the locking lever separates from the locking protrusion. At the same time, under the action of the guide protrusion, the locking lever is guided to the exit track. At this time, under the action of the spring restoring force, the sliding block moves outward, causing the mosquito coil to pop outward, making it easier for the user to pull out the end of the mosquito coil.

[0012] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that all directional terms such as up, down, front, back, left, and right appearing in the present invention are not intended to limit the present invention, but are only used to more clearly explain and interpret the present invention. Example
[0013] like Figure 1-6 As shown, this embodiment discloses a mosquito coil electric heater, including: a housing 1, the housing 1 having a slot 2 for accommodating the mosquito coil; a push-Push mechanism, the push-Push mechanism including: a sliding component 4 movably disposed within the housing 1, which can reciprocate by being pushed by the mosquito coil; an elastic reset element 5 connected to the sliding component 4; and a locking component 6 cooperating with the sliding component 4. During the movement of the sliding component 4 and the locking component 6 towards or away from each other, the locking or unlocking is switched through their cooperative structure. By providing a push-Push mechanism corresponding to the slot 2 in the housing 1, when it is necessary to remove the mosquito coil, the user presses the mosquito coil back into the slot 2, and the push-Push mechanism will pop the tail of the mosquito coil outwards, making it easy to remove.
[0014] The working principle is as follows: When the mosquito coil is inserted into slot 2, the mosquito coil moves the sliding component 4. The movement of the sliding component 4 causes the elastic reset element 5 to be tensioned and stored. The locking component 6 moves in the opposite direction to the sliding component 4, thus locking the mosquito coil. When it is necessary to remove the mosquito coil, pressing the mosquito coil a second time causes the mosquito coil to move the sliding component 4 again. The elastic reset element 5 releases its elasticity, and the sliding component 4 returns to its initial state (the state when the mosquito coil is not inserted). At the same time, the tail of the mosquito coil is pushed outward for easy removal by the user. Example
[0015] like Figure 1-6As shown, this embodiment discloses a mosquito coil electric heater, including: a housing 1, the housing 1 having a slot 2 for accommodating the mosquito coil; a push-Push mechanism, the push-Push mechanism including: a sliding component 4 movably disposed within the housing 1, which can reciprocate by being pushed by the mosquito coil; an elastic reset element 5 connected to the sliding component 4; and a locking component 6 cooperating with the sliding component 4. During the movement of the sliding component 4 and the locking component 6 towards or away from each other, the locking or unlocking is switched through their cooperative structure. By providing a push-Push mechanism corresponding to the slot 2 in the housing 1, when it is necessary to remove the mosquito coil, the user presses the mosquito coil back into the slot 2, and the push-Push mechanism will pop the tail of the mosquito coil outwards, making it easy to remove.
[0016] The working principle is as follows: When the mosquito coil is inserted into slot 2, the mosquito coil moves the sliding component 4. The movement of the sliding component 4 causes the elastic reset element 5 to store energy. The locking component 6 moves in the opposite direction to the sliding component 4, thus locking the mosquito coil. When it is necessary to remove the mosquito coil, pressing the mosquito coil a second time causes it to move the sliding component 4 again. The elastic reset element 5 releases its stored energy, and the sliding component 4 returns to its initial state (the state when the mosquito coil is not inserted). At the same time, the tail of the mosquito coil is pushed outward for easy removal by the user.
[0017] For better performance, the sliding assembly 4 includes a sliding block 7 slidably connected to the guide rail. The upper surface of the sliding block 7 is provided with a circulating groove. Inside the circulating groove are an entry track 8 and an exit track 9. A locking protrusion 10 and a guiding protrusion 11 are fixedly provided inside the circulating groove, with the guiding protrusion 11 corresponding to the locking protrusion 10. The locking protrusion 10 has a locking groove 12, and the exit track 9 has an inclined surface 13. The left end of the inclined surface 13 is flush with the locking groove 12, and the right end of the inclined surface 13 is higher than the entry track 8. The sliding block 7 has a push-fit part for bearing the pushing force of the mosquito coil, and the push-fit part has a docking groove 14. The Push-Push mechanism includes a tray 15 fixedly disposed inside the box body 1. The sliding assembly 4, the elastic reset element 5, and the locking assembly 6 are all disposed on the upper surface of the tray 15.
[0018] The elastic reset element 5 is a spring, one end of which is fixedly connected to the side wall of the support plate 15, and the other end of which is fixedly connected to the side wall of the sliding block 7. The locking assembly 6 includes a locking rod 16, both ends of which are provided with bent portions 17. One bent portion 17 of the locking rod 16 is rotatably connected to the bottom surface of the triangular groove 18 opened on the side wall of the support plate 15, and the other bent portion 17 of the locking rod 16 is slidably engaged with the uterine entry track 8. By setting the inclined surface 13, it is possible to effectively prevent the locking rod 16 from accidentally entering the uterine exit track 9 during the process of the sliding block 7 moving towards each other.
[0019] During use, when the mosquito coil is inserted into slot 2, the inner end of the low-pressure sliding block 7, through its mating groove 14, moves inward. As the sliding block 7 moves, the spring is stretched, causing the locking rod 16 to move towards the sliding block 7. The bent portion 17 of the locking rod 16 moves along the uterine inlet track 8 into the uterine cavity. Finally, the bent portion 17 of the locking rod 16 is engaged inside the locking protrusion 10, thus securing the mosquito coil. When the mosquito coil is pressed again, the bent portion 17 of the locking rod 16 separates from the locking protrusion 10. Simultaneously, under the action of the guide protrusion 11, the locking rod 16 is guided to the outlet track 9. At this point, under the restoring force of the spring, the sliding block 7 moves outward, causing the mosquito coil to pop outward. The connection between the spring and the locking rod 16 can be either with the spring on the outside and the locking rod 16 on the inside, or with the spring on the inside and the locking rod 16 on the outside. Therefore, the spring can store energy under tension or under compression.
[0020] For better performance, a switching mechanism is also included. This switching mechanism is linked to the Push-Push mechanism. When the Push-Push mechanism moves to the locked position in response to the insertion of the mosquito coil, it triggers the switching mechanism to conduct, energizing the heating element of the electric heater. When the Push-Push mechanism moves to the released position in response to another press, it triggers the switching mechanism to disengage, de-energizing the heating element. The switching mechanism uses a micro switch or photoelectric switch, eliminating the need for users to manually turn on the power switch or plug it into a power outlet after inserting the mosquito coil, and also eliminating the need to manually turn off the power switch or unplug it after removal, thus avoiding energy waste caused by no-load heating and improving safety.
[0021] For better performance, the micro switch can include a lever 19 fixedly mounted on the top wall of the housing. The lever 19 is made of insulating material and corresponds to the slot 2. One end of the lever 19 has a positive terminal 20, and the other end has a negative terminal 21. The positive terminal 20 is connected to the positive wire of the heating element of the electric heater, and the negative terminal 21 is connected to the negative wire of the heating element. When the mosquito coil 3 is inserted into the slot 2, the upper surface of the mosquito coil 3 presses against the lever 19, causing the positive terminal 20 to contact the negative terminal 21. This connects the heating element's wires, meaning that the heating element begins to heat up as soon as the mosquito coil 3 is inserted. Meanwhile, due to the arc-shaped design of the retaining plate 19, when the mosquito coil 3 is squeezed, the retaining plate 19 deforms, and the restoring potential energy of the retaining plate 19 acts on the mosquito coil 3, which can make the mosquito coil 3 make closer contact with the tray in the slot 2 and improve the volatilization efficiency of the mosquito coil 3.
[0022] Alternatively, the micro switch can also be configured as follows: including a stationary contact plate, a lifting plate 19 and its attached moving contact plate fixedly disposed on the top wall of the box body. The lifting plate 19 is disposed corresponding to the slot 2. When the mosquito coil 3 is inserted into the slot 2, the upper surface of the mosquito coil 3 presses the lifting plate 19, causing its attached moving contact plate to contact the stationary contact plate on the top wall, and the wire of the heating element is connected, so that the heating element starts to be powered on and heated after the mosquito coil 3 is inserted.
[0023] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and concept of this utility model, should be included within the scope of protection of this utility model.
