Description

Technical Field

[0001] The utility model relates to the technical field of heaters, in particular to a heater with a safety discharge function. Background Art

[0002] In the process of ornamental fish breeding, it is crucial to maintain the stability of the water temperature in the fish tank. As a key device for maintaining water temperature, the performance and safety of the fish tank heater directly affect the living environment and health of the fish. Traditional fish tank heaters lack effective protective devices, and the heater tube is easily damaged by collisions, foreign body intrusion, etc. This not only affects the service life of the heater, but may also cause safety hazards such as leakage due to damage to the tube.

[0003] However, the existing protective devices are cumbersome to install and disassemble, which brings inconvenience to the user's maintenance and cleaning work. In terms of protective effect, traditional protective devices are difficult to flexibly adjust the protection range according to actual needs and cannot meet the requirements of fish tanks of different sizes or special usage scenarios.

[0004] To this end, we propose a heater with safe discharge function. Utility Model Content

[0005] The main purpose of the utility model is to provide a heater with a safe discharge function, in order to prevent the existing protective devices from being cumbersome to install and disassemble, increasing the difficulty of user maintenance and cleaning, and being difficult to flexibly adjust the protection range to meet different needs, thereby improving the ease of maintenance and cleaning for users, and meeting the requirements of fish tanks of different sizes or special usage scenarios, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A heater with a safety discharge function, comprising a heater tube body, the exterior of the heater tube body being provided with two sets of protective devices arranged opposite to each other, the protective devices comprising a connecting seat, a connecting block being inserted into the inner side of the connecting seat, a limiting groove being provided on the outer wall of the connecting block close to the connecting seat, a groove being provided on the inner wall of the connecting seat, a limiting ball being provided in the groove and being insertable into the limiting groove, and the opposite side of the limiting ball being connected to the inner wall of the groove through a compression spring;

[0008] The end of the connecting block away from the connecting seat is fixedly connected to the first protective shell, the outer wall of the first protective shell is provided with a slide groove, the inside of the slide groove is slidably connected with a slider, the side of the slider away from the slide groove is fixedly connected to the second protective shell, the second protective shell is provided with multiple groups, and adjacent second protective shells are slidably connected by a third protective shell, and the inner walls of one end of two adjacent groups of the second protective shells in the two groups of relatively arranged protective devices are respectively provided with a first magnet and a second magnet, and the first magnet and the second magnet attract each other with opposite sexes.

[0009] By adopting the above technical solution, in the normal state, the compression spring presses the limit ball against the groove, and a part of the limit ball is inserted into the limit groove of the connecting block. At this time, the connecting block is stably fixed in the connecting seat, thus realizing the reliable connection between the protection device and the heater tube body. When it is necessary to disassemble the protection device, pull the connecting block outwards. The connecting block applies pressure to the limit ball, causing the limit ball to compress the compression spring and completely retract into the groove. At this time, the connecting block can be withdrawn from the connecting seat to complete the disassembly of the protection device. Through the cooperation of the limit ball and the compression spring, the rapid installation and disassembly of the protection device are realized, and stable connection and protection functions can be provided during normal use;

[0010] The connecting block is fixedly connected to the first protection housing. The sliding groove on the first protection housing cooperates with the sliding block, enabling the sliding block to drive the second protection housing to slide in the sliding groove. Since adjacent second protection housings are slidably connected through the third protection housing, relative sliding of multiple second protection housings can be achieved. When two sets of protection devices arranged oppositely approach each other, the first magnet and the second magnet provided on the inner walls of one ends of the two adjacent second protection housings that are close to each other will attract each other due to the property of opposite-sex attraction, causing these two second protection housings to fit tightly together, achieving a better protection effect on the heater tube body. When it is necessary to adjust the protection range or perform maintenance operations, the suction force of the magnet can be overcome, and the coverage range and state of the protection device can be changed by sliding the sliding block and the second protection housing.

[0011] Furthermore, the connecting seat is a horizontally arranged circular ring structure, and multiple groups of the limit grooves are arranged in a circular array.

[0012] By adopting the above technical solution, the circular ring shape is convenient for fitting and installing with the heater tube body, and can provide relatively uniform connection support. And multiple groups of the limit grooves are arranged in a circular array. In this way, when the connecting block is inserted into the connecting seat, limit fixation can be achieved from multiple angles and positions, increasing the stability and reliability of the connection, so that no matter at which rotation angle the connecting block is inserted, it can be fixed by the cooperation of the limit ball and the corresponding limit groove.

[0013] Furthermore, multiple groups of through holes are provided at equal distances on the outer sides of the first protection housing, the second protection housing and the third protection housing.

[0014] By adopting the above technical solution, heat is generated when the heater works. The through holes contribute to the dissipation of heat, avoiding too high temperature inside the protection housing, and also enabling the water in the fish tank to flow more freely around the protection housing, maintaining uniform distribution of the water temperature, and to a certain extent reducing the weight of the protection housing and the load of the entire protection device. When the water flows, the resistance to the protection device is reduced, and the impact and influence of the water flow on the protection device are reduced.

[0015] Furthermore, one end of the heater tube body is provided with a sealing plug, and the other end of the heater tube body is provided with a protective head.

[0016] By adopting the above technical solution, the sealing plug is used to prevent water from entering the interior of the heater tube body from one end, and the protective head is used to protect the other end of the heater tube body, which may play a protective role such as anti-collision and preventing foreign objects from entering.

[0017] Furthermore, the opposite ends of the two sets of connecting seats are respectively fixedly connected to the sealing plug and the protective head.

[0018] By adopting the above technical solution, this fixed connection method ensures the stability and sealing performance of the whole structure, enabling the heater to be in a relatively safe and stable environment during operation.

[0019] Furthermore, a temperature regulator and a power cord arranged in parallel are provided at one end of the sealing plug away from the connecting seat.

[0020] By adopting the above technical solution, the working temperature of the heater is set and adjusted through the temperature regulator, and the power cord is used to supply power to the heater.

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0022] (1) For the heater with a safe discharge function of the utility model, the protective device has the characteristics of quick installation and disassembly, which greatly facilitates the user's operation, significantly saves time and energy. The user can easily complete the installation and disassembly of the protective device without complex steps and professional tools. Whether it is the initial installation or subsequent maintenance and cleaning, it can be efficiently completed; during normal use, it can provide stable connection and excellent protection for the heater tube body. This stable connection effectively protects the heater tube body from being damaged by external factors, significantly reduces the possibility of safety risks such as electric leakage caused by tube body damage, thus greatly prolonging the service life of the heater and reducing the frequency and cost of the user replacing the heater.

[0023] (2) The heater with a safety discharge function of the present utility model has a protection range that can be flexibly adjusted according to the requirements of fish tanks of different sizes or special scenarios. This flexibility enables the heater to adapt to various complex usage environments. Whether it is a large fish tank or a fish tank with a special shape, appropriate protection can be obtained, greatly enhancing the applicability of the heater and meeting the diverse needs of users. The tight fit of each component in the protection device, especially the attraction of opposite poles between the first magnet and the second magnet provided on the inner wall at one end of the two relatively arranged second protection shells in the two groups of protection devices, effectively improves the protection effect and provides more comprehensive and rigorous protection for the heater tube body. At the same time, the structural design is reasonable, and each component works together, improving the overall performance of the heater, making it operate more reliably and reducing the probability of failures.

[0030] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] ​​In order to prevent the cumbersome installation and disassembly of the existing protective device, which increases the difficulty of user maintenance and cleaning, and the inability to flexibly adjust the protection range to meet different needs, thereby improving the ease of user maintenance and cleaning, and meeting the requirements of fish tanks of different sizes or special use scenarios, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, a heater with a safe discharge function includes a heater tube body 1. Two sets of oppositely arranged protective devices 2 are provided outside the heater tube body 1. The protective device 2 includes a connecting seat 3. A connecting block 4 is inserted inside the connecting seat 3. A limiting groove 5 is provided on the outer wall of the connecting block 4 close to the connecting seat 3. A groove 6 is provided on the inner wall of the connecting seat 3. A limiting ball 7 that can be inserted into the limiting groove 5 is provided in the groove 6. The opposite sides of the limiting ball 7 are connected to the inner wall of the groove 6 through a compression spring 8;

[0032] One end of the connecting block 4 far from the connecting seat 3 is fixedly connected to a first protective shell 9. A sliding groove 10 is provided on the outer wall of the first protective shell 9. A slider 11 is slidably connected inside the sliding groove 10. One side of the slider 11 far from the sliding groove 10 is fixedly connected to a second protective shell 12. There are multiple groups of the second protective shells 12, and adjacent second protective shells 12 are slidably connected through a third protective shell 20. First magnets 14 and second magnets 15 are respectively provided on the inner walls of one ends of the two relatively arranged protective devices 2 that are close to each other. The first magnet 14 and the second magnet 15 attract each other with opposite polarities.

[0033] During use, in the normal state, the compression spring 8 pushes the limiting ball 7 into the groove 6, and a part of the limiting ball 7 is inserted into the limiting groove 5 of the connecting block 4. At this time, the connecting block 4 is stably fixed inside the connecting seat 3, thereby realizing the reliable connection between the protective device 2 and the heater tube body 1. When it is necessary to disassemble the protective device 2, pull the connecting block 4 outwards. The connecting block 4 applies pressure to the limiting ball 7, causing the limiting ball 7 to compress the compression spring 8 and completely retract into the groove 6. At this time, the connecting block 4 can be withdrawn from the connecting seat 3, completing the disassembly of the protective device 2. Through the cooperation of the limiting ball 7 and the compression spring 8, the rapid installation and disassembly of the protective device 2 are realized, and at the same time, a stable connection and protection function can be provided during normal use;

[0034] The connecting block 4 is fixedly connected to the first protective housing 9. The sliding groove 10 on the first protective housing 9 cooperates with the sliding block 11, enabling the sliding block 11 to drive the second protective housing 12 to slide within the sliding groove 10. Since adjacent second protective housings 12 are slidably connected through the third protective housing 20, relative sliding of multiple second protective housings 12 can be achieved. When two sets of protective devices 2 arranged oppositely approach each other, the first magnet 14 and the second magnet 15 provided on the inner walls of one ends of the two adjacent second protective housings 12 that are approaching each other will attract each other due to the property of opposite-sex attraction, causing these two second protective housings 12 to fit tightly together, achieving a better protective effect on the heater tube body 1. When it is necessary to adjust the protection range or perform maintenance operations, the suction force of the magnet can be overcome, and the coverage range and state of the protective device 2 can be changed by sliding the sliding block 11 and the second protective housing 12.

[0035] Exemplarily, such as Figure 2 、 Figure 3 shown, the present utility model further includes that the connecting seat 3 is a horizontally arranged circular ring structure, and there are multiple groups of the limiting grooves 5 arranged in a circular array.

[0036] During use, the circular ring shape facilitates the fitting and installation with the heater tube body 1, and can provide relatively uniform connection support. And there are multiple groups of the limiting grooves 5 arranged in a circular array. In this way, when the connecting block 4 is inserted into the connecting seat 3, limit fixation can be achieved from multiple angles and positions, increasing the stability and reliability of the connection, so that no matter at which rotation angle the connecting block 4 is inserted, it can be fixed by the cooperation of the limiting ball 7 and the corresponding limiting groove 5.

[0037] Exemplarily, such as Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 shown, the present utility model further includes that multiple groups of through holes 13 are equidistantly arranged on the outer sides of the first protective housing 9, the second protective housing 12, and the third protective housing 20.

[0038] During use, when the heater works, heat is generated. The through holes 13 contribute to the dissipation of heat, avoiding excessive temperature inside the protective housing, and also enabling the water in the fish tank to flow more freely around the protective housing, maintaining a uniform distribution of water temperature. And to a certain extent, it reduces the weight of the protective housing, reduces the load of the entire protective device, and when the water flows, it reduces the resistance to the protective device and reduces the impact and influence of the water flow on the protective device.

[0039] Exemplarily, such as Figure 1 、 Figure 2 shown, the present utility model further includes that a sealing plug 16 is provided at one end of the heater tube body 1, and a protective head 17 is provided at the other end of the heater tube body 1.

[0040] In use, the sealing plug 16 is used to prevent water from entering the heater tube body 1 from one end, and the protective head 17 is used to protect the other end of the heater tube body, which may play a protective role such as anti-collision and preventing foreign objects from entering.

[0041] Exemplarily, as Figure 1 , Figure 2 , Figure 3 shown, the present invention further includes that opposite ends of two groups of the connecting seats 3 are respectively fixedly connected to the sealing plug 16 and the protective head 17.

[0042] In use, this fixed connection method ensures the stability and sealing of the entire structure, enabling the heater to operate in a relatively safe and stable environment during operation.

[0043] Exemplarily, as Figure 1 , Figure 2 shown, the present invention further includes that one end of the sealing plug 16 away from the connecting seat 3 is provided with a temperature regulator 18 and a power cord 19 arranged in parallel.

[0044] In use, the working temperature of the heater is set and adjusted through the temperature regulator 18, and the power cord 19 is used to supply power to the heater.

[0045] It should be noted that the present invention is a heater with a safety discharge function. When the protective device 2 needs to be installed, the connecting block 4 is inserted into the connecting seat 3. In the normal state, the compression spring 8 will push the limiting ball 7 into the limiting groove 5, so that the connecting block 4 is stably fixed in the connecting seat 3, thereby completing the connection between the protective device 2 and the heater tube body 1; if the protection range needs to be adjusted or maintenance operations are to be carried out, overcome the magnetic attraction, slide the slider 11 and the second protective housing 12 to change the coverage range and state of the protective device 2, and then connect the power cord 19 to the power supply when the heater is in use, set and adjust the working temperature of the heater through the temperature regulator 18, and then put the heater with the protective device 2 installed, connected to the power supply and the temperature set into the fish tank. When the protective device needs to be disassembled, pull the connecting block 4 outwards, so that the limiting ball 7 compresses the compression spring 8 and completely retracts into the groove 6.

[0046] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
