Description

Technical Field

[0001] This utility model belongs to the field of atomizer technology, and in particular relates to an atomizer with an easy-to-replace atomizing head. Background Technology

[0002] A nebulizer is used to atomize a test solution. It is a crucial component of an atomization system, and its performance significantly impacts the precision of the measurement and reduces chemical interference. Therefore, nebulizers are required to produce stable sprays, fine and uniform droplets, and high atomization efficiency.

[0003] For example, Chinese patent CN222625057U discloses an atomizer with an easy-to-replace atomizing head. This solution includes an atomizer body and an atomizing head. The atomizer body has four slots on its outer side, and the atomizing head has four sliding holes on its outer side. Each of the four sliding holes has a locking block slidably connected to its inner wall. An operating ring is rotatably connected to the outer side of the atomizing head. In this application, by setting the slots and locking blocks, when the positions of the four magnets coincide with the positions of the four locking blocks, the magnetic attraction of the magnets can cause the locking blocks to detach from the slots, thus facilitating the insertion of the atomizer body into the atomizing head. After the insertion is completed, the operating ring can be twisted at will, at which point the magnets and locking blocks are misaligned, and the locking blocks lose their magnetic attraction and fall back into the slots. This ensures the firm connection between the atomizer body and the atomizing head while facilitating installation, preventing detachment and waste of medication.

[0004] The aforementioned patent has the following problems:

[0005] This patented device has several drawbacks in use. For example, the sealing ring is prone to damage after prolonged use, affecting its sealing performance and leading to leakage. Furthermore, the sealing ring is not easily replaceable, creating a functional defect. Additionally, the end of the atomizing head furthest from the atomizer is typically made of plastic, making it susceptible to breakage from impacts. This device requires replacing the entire atomizing head, increasing maintenance costs. Therefore, we propose an atomizer with a replaceable atomizing head. Utility Model Content

[0006] The purpose of this invention is to provide an atomizer with an easy-to-replace atomizing head, so as to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides an atomizer with an easily replaceable atomizing head, comprising an atomizer body, an atomizing head body, and a nozzle, wherein a heating plate is fixedly installed inside the atomizing head body, and further comprising:

[0008] An annular groove is formed on the atomizer body. Two guide plates are fixedly installed on the atomizer body. Two semicircular rings are rotatably installed on the atomizer body. A sealing gasket is inserted into the annular groove and located within the two semicircular rings. One end of the atomizing head body is located between the two semicircular rings. The guide plates extend into the atomizing head body. A threaded groove is formed on the side of the atomizing head body that is fixedly located on the heating plate away from the atomizer body. A threaded tube is threadedly installed in the threaded groove. The nozzle is fixedly installed on one side of the threaded tube.

[0009] Two sets of fixing components are located inside two semicircular rings and are used to fix the semicircular rings respectively.

[0010] In this technical solution, when the sealing gasket needs to be replaced, the fixing component is used to release the fixing of the semi-circular ring. Then, the semi-circular ring can be rotated and opened. After both semi-circular rings are opened, the atomizer head body and the sealing gasket will be released from fixation. At this time, the operator can pull the atomizer head body out from the two guide plates on the atomizer body, and then pull the sealing gasket out from the annular groove. The operator can then insert the new sealing gasket back into the annular groove, and then insert the atomizer head body into the two guide plates on the atomizer body, so that one end of the atomizer head body is in close contact with the sealing gasket. Then, the semi-circular ring can be rotated again to return the two semi-circular rings to their original positions. At this time, one end of the atomizer head body and the sealing gasket are both located between the two semi-circular rings. The two semi-circular rings will limit the position of the atomizer head body, and the sealing gasket will deform due to the pressure of one end of the atomizer head body. Under the action of the two guide plates, the atomizer head body will not rotate on the atomizer body. At this time, the fixing component fixes the position of the semi-circular ring.

[0011] When it is necessary to disassemble and replace the nozzle, the operator can rotate the nozzle, which will drive the threaded tube to rotate. Under the action of the thread, the threaded tube will rotate in the thread groove and move outward until the threaded tube is removed from the thread groove. At this time, the nozzle will be removed, and then the new nozzle can be installed.

[0012] In the above technical solution, the fixing component further includes:

[0013] A slide groove is formed inside a semi-circular ring. A limiting block is slidably installed inside the slide groove. One end of the limiting block extends into the atomizer body, and a pull rod is fixedly installed at the other end of the limiting block. One end of the pull rod passes through one side of the slide groove and extends to the outside. A spring is provided on the pull rod and inside the slide groove.

[0014] In this technical solution, the operator pulls the lever by hand, which will cause the limiting block to move. At this time, the spring will be compressed and contracted until one end of the limiting block is completely pulled out of the atomizer body. At this time, the semi-circular ring will be released from the fixation, and then the semi-circular ring can be rotated and opened.

[0015] In the above technical solution, furthermore, both ends of the spring are tightly welded to the other end of the limiting block and the inner wall of the slide groove, respectively, and one end of the limiting block is inserted into the atomizer body.

[0016] In this technical solution, the structure of the spring is ensured to be stable, and one end of the limiting block can be inserted into the atomizer body.

[0017] In the above technical solution, the sealing gasket is slidably connected to the two guide plates, and the atomizing head body is slidably connected to the two guide plates.

[0018] In this technical solution, the sealing gasket is ensured to slide on the two guide plates, and the atomizing head body is also ensured to slide on the two guide plates.

[0019] Furthermore, in the above technical solution, the guide plate and the atomizer body are integrally formed.

[0020] In this technical solution, the structural stability between the guide plate and the atomizer body is ensured.

[0021] In the above technical solution, furthermore, the atomizing head body is in close contact with the sealing gasket.

[0022] In this technical solution, the sealing gasket is made of a relatively soft material, ensuring that the sealing gasket can seal between the atomizer body and the atomizing head body.

[0023] In the above technical solution, the sealing gasket is further described as having a ring structure.

[0024] In this technical solution, the sealing gasket is guaranteed to seal between the atomizer body and the atomizing head body.

[0025] The beneficial effects of this utility model are:

[0026] 1. This atomizer with an easy-to-replace atomizing head ensures that the sealing gasket can be replaced through the cooperation of the semi-circular ring, annular groove, sealing gasket, guide plate and two sets of fixing components. This avoids damage to the sealing gasket due to prolonged use, which affects the sealing effect and prevents leakage.

[0027] 2. This atomizer, which facilitates the replacement of the atomizing head, ensures that the nozzle can be replaced through the cooperation between the nozzle, threaded groove, and threaded tube. It avoids damage to the nozzle caused by collisions, preventing the nozzle from being unable to be replaced and thus preventing damaged nozzles from affecting the use of the entire device, thereby reducing the maintenance cost of the entire device.

[0037] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0038] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0039] Example 1: This example provides an atomizer with an easily replaceable atomizing head, including an atomizer body 1, an atomizing head body 2, and a nozzle 3. A heating plate 4 is fixedly installed inside the atomizing head body 2, and it also includes:

[0040] An annular groove 12 is formed on the atomizer body 1. Two guide plates 13 are fixedly installed on the atomizer body 1. Two semi-circular rings 7 are rotatably installed on the atomizer body 1. A sealing gasket 6 is inserted and installed in the annular groove 12 and located in the two semi-circular rings 7. One end of the atomizing head body 2 is located between the two semi-circular rings 7. The guide plate 13 extends into the atomizing head body 2. A threaded groove 14 is formed in the atomizing head body 2 and located on the side of the heating plate 4 away from the atomizer body 1. A threaded tube 5 is threadedly installed in the threaded groove 14. The nozzle 3 is fixedly installed on one side of the threaded tube 5.

[0041] Two sets of fixing components are located inside the two semicircular rings 7 respectively, and are used to fix the semicircular rings 7 respectively.

[0042] In use, when the sealing gasket 6 needs to be replaced, the fixing component is used to release the fixing of the semi-circular ring 7. Then, the semi-circular ring 7 can be rotated and opened. After both semi-circular rings 7 are opened, the atomizer head body 2 and the sealing gasket 6 will be released from their fixation. At this time, the operator can pull the atomizer head body 2 out from the two guide plates 13 on the atomizer body 1, and then pull the sealing gasket 6 out from the annular groove 12. Subsequently, the operator can insert the new sealing gasket 6 back into the annular groove 12, and then insert the atomizer head body 2 into the atomizer body. On the two guide plates 13 on 1, one end of the atomizer head body 2 is in close contact with the sealing gasket 6. Then, the semi-circular ring 7 can be rotated again to return the two semi-circular rings 7 to their original positions. At this time, one end of the atomizer head body 2 and the sealing gasket 6 are both located between the two semi-circular rings 7. The two semi-circular rings 7 will limit the position of the atomizer head body 2, and the sealing gasket 6 will deform due to the pressure of one end of the atomizer head body 2. Under the action of the two guide plates 13, the atomizer head body 2 will not rotate on the atomizer body 1. At this time, the fixed component is set to fix the position of the semi-circular ring 7.

[0043] When it is necessary to disassemble and replace the nozzle 3, the operator can rotate the nozzle 3, which will drive the threaded tube 5 to rotate. Under the action of the thread, the threaded tube 5 will rotate in the threaded groove 14 and move outward until the threaded tube 5 is removed from the threaded groove 14. At this time, the nozzle 3 will be disassembled, and then the new nozzle 3 can be installed.

[0044] Example 2:

[0045] This embodiment provides an atomizer with an easily replaceable atomizing head. In addition to the technical solutions described in the above embodiments, it also has the following technical features: the fixing component includes:

[0046] The slide 8 is opened inside the semi-circular ring 7. A limiting block 10 is slidably installed inside the slide 8. One end of the limiting block 10 extends into the atomizer body 1, and a pull rod 11 is fixedly installed on the other end of the limiting block 10. One end of the pull rod 11 passes through one side of the slide 8 and extends to the outside. A spring 9 is provided on the pull rod 11 and inside the slide 8.

[0047] When the staff pulls the lever 11, the lever 11 will cause the limiting block 10 to move. At this time, the spring 9 will be compressed and contracted until one end of the limiting block 10 is completely pulled out from the atomizer body 1. At this time, the semi-circular ring 7 will be released from the fixation, and then the semi-circular ring 7 can be rotated and opened.

[0048] Example 3:

[0049] This embodiment provides an atomizer that facilitates the replacement of the atomizing head. In addition to the technical solutions of the above embodiments, it also has the following technical features: the two ends of the spring 9 are respectively tightly welded to the other end of the limiting block 10 and the inner wall of the slide groove 8, and one end of the limiting block 10 is inserted into the atomizer body 1.

[0050] Among these measures, the structure of the spring 9 is kept stable, and one end of the limiting block 10 is inserted into the atomizer body 1.

[0051] Example 4:

[0052] This embodiment provides an atomizer that facilitates the replacement of the atomizing head. In addition to the technical solutions of the above embodiments, it also has the following technical features: the sealing gasket 6 is slidably connected to the two guide plates 13, and the atomizing head body 2 is slidably connected to the two guide plates 13.

[0053] Specifically, this ensures that the sealing gasket 6 can slide on the two guide plates 13, and that the atomizing head body 2 can slide on the two guide plates 13.

[0054] Example 5:

[0055] This embodiment provides an atomizer that facilitates the replacement of the atomizing head. In addition to the technical solutions of the above embodiments, it also has the following technical features: the guide plate 13 and the atomizer body 1 are integrally formed.

[0056] Among these measures, it is essential to ensure the structural stability between the guide plate 13 and the atomizer body 1.

[0057] Example 6:

[0058] This embodiment provides an atomizer that facilitates the replacement of the atomizing head. In addition to the technical solutions of the above embodiments, it also has the following technical features: the atomizing head body 2 is in close contact with the sealing gasket 6.

[0059] The sealing gasket 6 is made of a relatively soft material, which ensures that the sealing gasket 6 can seal between the atomizer body 1 and the atomizer head body 2.

[0060] Example 7:

[0061] This embodiment provides an atomizer that facilitates the replacement of the atomizing head. In addition to the technical solutions of the above embodiments, it also has the following technical features: the sealing gasket 6 has a ring structure.

[0062] Among them, the sealing gasket 6 is designed to seal the atomizer body 1 and the atomizing head body 2.

[0063] Working principle: When the sealing gasket 6 needs to be replaced, the operator pulls the lever 11 by hand. The lever 11 will cause the limiting block 10 to move. At this time, the spring 9 will be compressed and contracted until one end of the limiting block 10 is completely pulled out of the atomizer body 1. At this time, the semi-circular ring 7 will be released from its fixation. Then, the semi-circular ring 7 can be rotated and opened. After both semi-circular rings 7 are opened, the atomizer head body 2 and the sealing gasket 6 will be released from their fixation. At this time, the operator can pull the atomizer head body 2 out from the two guide plates 13 on the atomizer body 1, and then pull the sealing gasket 6 out from the annular groove 12. Then, the operator can insert the new sealing gasket 6 back into the annular groove 12, and then insert the atomizer head body 2... On the two guide plates 13 on the atomizer body 1, one end of the atomizer head body 2 is in close contact with the sealing gasket 6. Then, the semicircular ring 7 can be rotated again to return the two semicircular rings 7 to their original positions. At this time, one end of the atomizer head body 2 and the sealing gasket 6 are both located between the two semicircular rings 7. The two semicircular rings 7 will limit the position of the atomizer head body 2, and the sealing gasket 6 will deform due to the pressure of one end of the atomizer head body 2. Under the action of the two guide plates 13, the atomizer head body 2 will not rotate on the atomizer body 1. At this time, under the action of the spring 9 rebound force, the spring 9 will drive the limiting block 10 to move towards the atomizer body 1 until one end of the limiting block 10 is inserted into the atomizer body 1. At this time, the position of the semicircular ring 7 will be fixed.

[0064] When it is necessary to disassemble and replace the nozzle 3, the operator can rotate the nozzle 3, which will drive the threaded tube 5 to rotate. Under the action of the thread, the threaded tube 5 will rotate in the threaded groove 14 and move outward until the threaded tube 5 is removed from the threaded groove 14. At this time, the nozzle 3 will be disassembled, and then the new nozzle 3 can be installed.

[0065] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
