Description

Technical Field

[0001] This utility model relates to the field of disinfection equipment technology, and in particular to a heating atomizer. Background Technology

[0002] Fog disinfection equipment is widely used in livestock farming and public health, as well as other fields requiring space disinfection. This equipment is equipped with a heated atomizer, which heats and atomizes the disinfectant solution. The heated atomizer consists of a housing, a heating element, and an atomizing tube, all housed within the housing. As the disinfectant solution passes through the atomizing tube, it is heated by the heating element, transforming the liquid into a mixed fog. This fog is then sprayed through the nozzle, resulting in better suspension and disinfection.

[0003] In related technologies, the atomizing tube has a spiral coil structure, which is beneficial for thorough heating. However, the coil structure is not only difficult to manufacture, but also results in a large temperature difference between the two ends of the atomizing tube. This affects the operation of the heating element and the atomization effect of the disinfectant. In addition, it has been found that the high temperature during disinfectant atomization causes some solid substances to form on the inner wall of the atomizing tube. With long-term use, these substances can easily accumulate and clog the atomizing tube. Furthermore, the spiral shape of the coil structure makes it difficult to clean and maintain with cleaning tools, resulting in poor practicality. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a heating atomizer that not only fully heats the disinfectant but also has lower manufacturing difficulty. In addition, the atomizing tube is heated more evenly, reducing the risk of damage to the heating element or abnormal atomization caused by excessively high local temperatures. Furthermore, the atomizing tube is easier to clean and maintain, resulting in better practicality.

[0005] A heating atomizer according to an embodiment of the present invention includes a housing, an atomizing tube, and a heating element. The atomizing tube is disposed in the housing and forms a plurality of straight tube segments arranged side by side and connected sequentially. At least one end of each straight tube segment is connected to a connector. The connector has a connecting channel communicating with the straight tube segment. The connector is detachable and / or has a cleaning hole. The cleaning hole is coaxial with and communicates with the straight tube segment. The cleaning hole has a detachable sealing part. The heating element is disposed in the housing for heating the atomizing tube.

[0006] The heating atomizer according to the embodiments of the present invention has at least the following beneficial effects:

[0007] In this application, the connecting channel can be used to connect to an external inlet or outlet pipe, or to connect two adjacent straight pipe sections in the conveying direction of the atomizing tube. The atomizing tube includes multiple straight pipe sections arranged side by side and connected sequentially, forming a back-and-forth bending structure. Thus, with a fixed shell volume, the atomizing tube is relatively long, allowing for thorough heating and atomization of the disinfectant. Moreover, the larger number of straight pipe sections makes it easier to manufacture compared to a spiral coil structure. Furthermore, the back-and-forth bending of the atomizing tube allows the same position of the heating element to heat multiple positions in the conveying direction of the atomizing tube, resulting in more uniform heating of the atomizing tube and more uniform heat absorption of the disinfectant. This effectively reduces the risk of damage to the heating element or abnormal atomization caused by excessively high local temperatures. In addition, at least one end of the straight tube section is connected to a connector, which is detachable, and / or the connector is provided with a cleaning hole that is coaxial with and communicates with the straight tube section. Thus, when it is necessary to clean the inside of the atomizing tube, the connector can be removed to expose at least one end of the straight tube section, making it convenient to reach into the straight tube section with a brushing tool for cleaning and maintenance. Alternatively, the sealing part can be removed to open the cleaning hole that is coaxial with and communicates with the straight tube section, which is also convenient to reach into the straight tube section with a brushing tool for cleaning and maintenance, thus improving practicality.

[0008] According to some embodiments of the present invention, the number of straight pipe sections is N, satisfying: N = 2n, where n is a positive integer; the connector includes multiple connectors, which are detachably connected to the same end of the multiple straight pipe sections, wherein two connectors are used to connect the feed pipe and the discharge pipe respectively.

[0009] According to some embodiments of this utility model, n is greater than or equal to 2, and the remaining connectors are divided into at least one group. Each group of connectors includes two connectors, and a connecting bend is installed between the two connectors in the same group so that two adjacent straight pipe sections in the atomizing tube conveying direction are connected.

[0010] According to some embodiments of the present invention, the number of straight pipe sections is N, satisfying: N = 2n, where n is a positive integer; the connector is connected to the same end of all the straight pipe sections, and the connector is provided with the connection channel and the cleaning hole for each straight pipe section, wherein the two connection channels are respectively used to connect the feed pipe and the discharge pipe.

[0011] According to some embodiments of this utility model, n is greater than or equal to 2, and the remaining connection channels are divided into at least one group. Each group of connection channels includes two connection channels. The two connection channels in the same group are connected through a connecting hole so that some adjacent straight pipe sections in the conveying direction of the atomizing tube are connected.

[0012] According to some embodiments of the present invention, a bent pipe section is integrally formed between the ends of two adjacent straight pipe sections in the conveying direction of the atomizing tube, away from the joint, so that multiple straight pipe sections are connected in sequence.

[0013] According to some embodiments of the present invention, the heating element includes a heating tube disposed inside the housing, and a plurality of straight tube segments are parallel to the heating tube and arranged circumferentially along the heating tube.

[0014] According to some embodiments of the present invention, a limiting plate is installed inside the housing, and the limiting plate is provided with a plurality of limiting holes, which are respectively for the heating tube and the plurality of straight pipe sections to pass through.

[0015] According to some embodiments of the present invention, the heating element further includes a heat-conducting portion, which fills the housing and covers the outer periphery of the heating tube and the plurality of straight tube sections.

[0016] According to some embodiments of the present invention, the connector is located outside the housing when it is detachable.

[0036] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0037] The following is for reference. Figures 1 to 8 A heating atomizer according to an embodiment of the present invention is described.

[0038] like Figures 1 to 8 As shown, the heating atomizer according to an embodiment of the present invention includes a housing 100, an atomizing tube 200, and a heating element 300.

[0039] For example, the housing 100 may have a heating chamber, and the atomizing tube 200 may be located entirely or partially inside the housing 100. The atomizing tube 200 may have multiple straight tube segments 201 arranged side by side and connected sequentially. For example, there may be 2, 3, 4 or other suitable number of straight tube segments 201. The multiple straight tube segments 201 may be parallel to each other and extend along the length of the housing 100. The directions of conveying disinfectant in two adjacent straight tube segments 201 are opposite.

[0040] At least one end of the straight pipe section 201 is connected to a connector 202. Specifically, the connector 202 can be connected to one end of the straight pipe section 201, or it can be connected to both ends of the straight pipe section 201. A connector 202 can be connected to a single straight pipe section 201, or it can be connected to all straight pipe sections 201. The connector 202 is provided with a connection channel 203 communicating with the straight pipe section 201. The connection channel 203 can be used to connect to an external feed pipe 400 or a discharge pipe 500. The feed pipe 400 allows the disinfectant to be heated and atomized to enter the atomizing pipe 200, and the discharge pipe 500 allows the heated and atomized disinfectant to be discharged. The discharge pipe 500 can be provided with an atomizing nozzle 501. The connection channel 203 can also be used to connect two adjacent straight pipe sections 201 in the conveying direction of the atomizing pipe 200.

[0041] The connector 202 is detachable. For example, the connector 202 can be threaded or snapped into the straight pipe section 201. When it is necessary to transport disinfectant, the connector 202 is not detached. When it is necessary to clean and maintain the straight pipe section 201, the connector 202 is detached.

[0042] Alternatively, the connector 202 may have a cleaning hole 204, which is coaxial with and connected to the straight pipe section 201. The cleaning hole 204 may have a removable plug 205. For example, the cleaning hole 204 may be a threaded hole, and the plug 205 may be a screw plug connected to the cleaning hole 204. Alternatively, the plug 205 may be directly inserted into the cleaning hole 204. When disinfectant needs to be transported, the plug 205 seals the cleaning hole 204 to prevent disinfectant from flowing out. When the straight pipe section 201 needs to be cleaned and maintained, the plug 205 can be removed. It should be noted that the cleaning hole 204 is connected to the corresponding straight pipe section 201 through a connecting channel 203.

[0043] The heating element 300 is disposed in the housing 100. For example, the heating element 300 may be located in the heating chamber of the housing 100. The heating element 300 is used to heat the disinfectant in the atomizing tube 200 so that the disinfectant passing through the atomizing tube 200 is heated and atomized.

[0044] In this application, the atomizing tube 200 includes multiple straight tube segments 201 arranged side-by-side and connected sequentially, forming a back-and-forth bending structure. Thus, with a fixed volume of the housing 100, the atomizing tube 200 is relatively long, allowing for sufficient heating of the disinfectant. Furthermore, the larger number of straight tube segments 201 simplifies manufacturing compared to a spiral coil structure. In addition, the back-and-forth bending of the atomizing tube 200 allows the heating element 300 to heat multiple locations along the conveying direction of the atomizing tube 200 from the same position, resulting in more uniform heating and more even heat absorption by the disinfectant. This effectively reduces the risk of damage to the heating element 300 or abnormal atomization due to localized overheating. Furthermore, at least one end of the straight tube section 201 is connected to a connector 202, which is detachable, and / or the connector 202 is provided with a cleaning hole 204, which is coaxial with and communicates with the straight tube section 201. Thus, when cleaning the inside of the atomizing tube 200 is required, the connector 202 can be removed to expose at least one open end of the straight tube section 201, facilitating cleaning and maintenance by inserting a brush tool into the straight tube section 201. Alternatively, the sealing part 205 can be removed to open the cleaning hole 204, which is coaxial with and communicates with the straight tube section 201, similarly facilitating cleaning and maintenance by inserting a brush tool into the straight tube section 201. In addition, this application allows the use of atomizing tubes 200 with larger diameters, resulting in better atomization, higher delivery efficiency, and greater practicality.

[0045] It should be noted that the two adjacent straight pipe sections 201 mentioned in this utility model do not refer to the two straight pipe sections 201 that are closest in spatial distance, but rather to the two straight pipe sections 201 that are closest and directly connected along the conveying direction of the atomizing pipe 200.

[0046] like Figures 1 to 4 As shown, in some embodiments of this utility model, the number of straight pipe sections 201 is N, satisfying: N = 2n, where n is a positive integer; the connector 202 includes multiple connectors, which are detachably connected to the same end of multiple straight pipe sections 201, wherein two connectors 202 are used to connect the feed pipe 400 and the discharge pipe 500 respectively.

[0047] For example, the two ends of the atomizing tube 200 in the conveying direction form an inlet end and an outlet end, respectively. n can be 1, 2, 3, or other suitable numbers. Correspondingly, the number of straight pipe sections 201 can be 2, 4, 6, or other suitable numbers. The number of straight pipe sections 201 is even. Thus, the inlet end and the outlet end will be located at the same end of two of the straight pipe sections 201. Multiple connectors 202 can be detachably connected to the ends of multiple straight pipe sections 201 near the inlet end and the outlet end, respectively. The two connectors 202 connected to the inlet end and the outlet end are used to connect to the external inlet pipe 400 and the outlet pipe 500, respectively, to facilitate the feeding and discharging of disinfectant.

[0048] In this embodiment, multiple connectors 202 are detachably connected to the same end of multiple straight pipe sections 201. This makes it easier to disassemble multiple connectors 202 at the same time, and makes cleaning and maintenance of the straight pipe sections 201 more convenient. Moreover, since the number of straight pipe sections 201 is even, the feed end and the discharge end of the atomizing tube 200 can be located on the same side. This not only makes disassembly and assembly more convenient, but also allows the discharge end with a higher temperature and the feed end with a lower temperature to be close together, which can distribute heat evenly and effectively reduce the risk of damage to the heating element 300 or abnormal atomization caused by excessively high local temperatures. It can also prevent the atomization effect from decreasing due to excessively low feed end temperature.

[0049] like Figures 1 to 4 As shown, in some embodiments of this utility model, n is greater than or equal to 2, and the remaining connectors 202 are divided into at least one group. Each group of connectors 202 includes two connectors 202. A connecting bend 206 is installed between the two connectors 202 in the same group so that two adjacent straight pipe sections 201 in the conveying direction of the atomizing tube 200 are connected.

[0050] For example, n can be equal to 2. In this case, there are 4 straight pipe sections 201, and 4 connectors are set accordingly. Two connectors 202 are used to connect the feed pipe 400 and the discharge pipe 500 respectively. The other two connectors 202 form a group. A connecting bend 206 is installed between these two connectors 202. The disinfectant enters the first straight pipe section 201 from the feed pipe 400. After flowing through the first straight pipe section 201, it enters the second straight pipe section 201 from the end of the first straight pipe section 201 away from the feed pipe 400. After flowing through the second straight pipe section 201, it enters the third straight pipe section 201 through the connecting bend 206. After flowing through the third straight pipe section 201, it enters the fourth straight pipe section 201 from the end of the third straight pipe section 201 away from the connecting bend 206. After flowing through the fourth straight pipe section 201, it is discharged from the discharge pipe 500.

[0051] In this embodiment, this configuration allows all straight pipe sections 201 to be connected sequentially to form an atomizing pipe 200, which makes it easier to transport and heat the atomized disinfectant.

[0052] When the number of straight pipe sections 201 is N, satisfying: N = 2n, where n is a positive integer, such as Figures 5 to 7 As shown, in some embodiments of this utility model, there may be only one connector 202. The connector 202 is connected to the same end of all straight pipe sections 201. The connector 202 is provided with a connecting channel 203 and a cleaning hole 204 for each straight pipe section 201. The two connecting channels 203 are used to connect the feed pipe 400 and the discharge pipe 500, respectively. Specifically, the multiple connecting channels 203 are respectively connected to the multiple straight pipe sections 201. The multiple cleaning holes 204 can be provided on the side of the multiple connecting channels 203 opposite to the multiple straight pipe sections 201. The cleaning holes 204 are coaxial with the corresponding straight pipe section 201 and are connected to the corresponding straight pipe section 201 through the corresponding connecting channel 203.

[0053] In this embodiment, the connector 202 is configured as one and connected to the same end of all straight pipe sections 201. The connector 202 is provided with multiple connection channels 203 that communicate with multiple straight pipe sections 201 respectively, and multiple cleaning holes 204 that are coaxial with multiple straight pipe sections 201 respectively. In this way, it is more convenient to clean and maintain the straight pipe sections 201. Moreover, the number of straight pipe sections 201 is even, so the feed end and the discharge end of the atomizing tube 200 can be located on the same side. This not only makes it convenient for the connector 202 to connect to both the feed end and the discharge end, but also allows the discharge end with a higher temperature and the feed end with a lower temperature to be close together, which can evenly distribute the heat. This can effectively reduce the damage to the heating element 300 or abnormal atomization caused by excessively high local temperature, and can also avoid the atomization effect from being reduced due to excessively low feed end temperature.

[0054] like Figures 5 to 7 As shown, in some embodiments of this utility model, n is greater than or equal to 2, and the remaining connection channels 203 are divided into at least one group. Each group of connection channels 203 includes two connection channels 203. The two connection channels 203 in the same group are connected through a connecting hole 207 so that a portion of two adjacent straight pipe sections 201 in the conveying direction of the atomizing tube 200 are connected.

[0055] For example, n can be equal to 2. In this case, there are 4 straight pipe sections 201, and 4 connecting channels 203 and 4 cleaning holes 204. Two of the connecting channels 203 are used to connect the feed pipe 400 and the discharge pipe 500, respectively. The other two connecting channels 203 form a group, which are connected by a connecting hole 207. The disinfectant enters the first straight pipe section 201 from the feed pipe 400, flows through the first straight pipe section 201, and then enters the second straight pipe section 201 from the end of the first straight pipe section 201 away from the feed pipe 400. After flowing through the second straight pipe section 201, it enters the third straight pipe section 201 through the connecting hole 207. After flowing through the third straight pipe section 201, it enters the fourth straight pipe section 201 from the end of the third straight pipe section 201 away from the connecting hole 207. After flowing through the fourth straight pipe section 201, it is discharged from the discharge pipe 500.

[0056] In this embodiment, this configuration allows all straight pipe sections 201 to be connected sequentially to form an atomizing pipe 200, which makes it easier to transport and heat the atomized disinfectant.

[0057] like Figures 1 to 6 As shown, in some embodiments of this utility model, a bent section 208 is integrally formed between the ends of two adjacent straight pipe sections 201 in the conveying direction of the atomizing tube 200 that are away from the connector 202, so that multiple straight pipe sections 201 are connected in sequence. In this embodiment, the bent section 208 and the straight pipe sections 201 connected at both ends form a U-shaped tube-like structure. The bent section 208 enables all straight pipe sections 201 to be connected in sequence to form a long strip atomizing tube 200, thereby making it more convenient to convey and heat the disinfectant.

[0058] like Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, in some embodiments of this utility model, the heating element 300 includes a heating tube 301, which is disposed inside the housing 100. A plurality of straight tube segments 201 are parallel to the heating tube 301 and arranged circumferentially along the heating tube 301.

[0059] In this embodiment, the heating tube 301 is positioned at the exact center of multiple straight tube segments 201 and is surrounded by multiple straight tube segments 201, thereby enabling efficient and uniform heating of the atomizing tube 200, improving heating efficiency, and reducing heat loss.

[0060] It should be noted that the heating element 301 can be an electric heating element. In addition, in some other embodiments of this utility model, the heating element 301 can also be replaced with an electric heating wire.

[0061] like Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, in some embodiments of this utility model, a limiting plate 101 is installed inside the housing 100. The limiting plate 101 is provided with multiple limiting holes, which are respectively used for the heating tube 301 and multiple straight pipe sections 201 to pass through.

[0062] In this application, a limiting plate 101 is provided, which has a better limiting effect on the heating tube 301 and multiple straight pipe sections 201, and avoids the heating tube 301 and straight pipe sections 201 from moving arbitrarily and affecting the heating effect.

[0063] like Figure 2 and Figure 8 As shown, in some embodiments of this utility model, the heating element 300 further includes a heat-conducting part 302, which fills the housing 100 and covers the outer periphery of the heating tube 301 and multiple straight tube sections 201. The heat-conducting part 302 may be an aluminum block or other material with good thermal conductivity poured into the heating cavity of the housing 100, and the heat-conducting part 302 may fill the entire heating cavity of the housing 100.

[0064] In this embodiment, a heat-conducting part 302 is provided. After the heating tube 301 heats the heat-conducting part 302, the heat-conducting part 302 heats the straight pipe section 201 from various positions in the circumferential direction and the length direction. The heating of the straight pipe section 201 is more comprehensive and uniform, and thus the heating of the disinfectant is more comprehensive and uniform. This not only enables the disinfectant to be heated to the required temperature quickly, but also reduces the situation of carbonization caused by excessive local temperature of the disinfectant, making it more practical.

[0065] like Figures 1 to 3 As shown, in some embodiments of this utility model, the connector 202 is located outside the housing 100 when it is detachable. For example, it can be located outside one end of the housing 100 in the longitudinal direction, which makes it more convenient to detach the connector 202.

[0066] In some embodiments of this utility model, a temperature control switch may be provided at the limiting plate 101. The temperature control switch can detect the temperature of the atomizing tube 200 after it is heated. When the detected temperature reaches a preset value, the temperature control switch controls the circuit of the heating tube 301 to disconnect and stop heating, so as to avoid damage to the atomizing tube 200 due to excessive temperature and to prevent the disinfectant from carbonizing.

[0067] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
