Description

Technical Field

[0001] This utility model relates to the field of mycoplasma detectors, and in particular to a sealed mycoplasma detector. Background Technology

[0002] A mycoplasma detector is an instrument that can quickly detect mycoplasma in samples. For example, the mycoplasma detector disclosed in announcement number CN205374314U includes an incubation plate, a heating plate installed at the bottom of the incubation plate, and photoelectric plates and photoelectric detection plates installed on opposite sides of the incubation plate. The heating plate is equipped with a temperature sensor to maintain the sample temperature. The photoelectric plate has a light source, and the photoelectric detection plate has a color sensor. The light emitted by the photoelectric plate passes through the detection holes on the incubation plate and the sample tubes placed in the sample tube placement holes, illuminating the photoelectric detection plate. The color sensor identifies color changes and determines the detection result, offering advantages such as low error and high efficiency. However, if the external light is too strong, it can adversely affect the color sensor, leading to misjudgments. Therefore, this invention further adds a sealed mycoplasma detector. Utility Model Content

[0003] The purpose of this application is to provide a sealed mycoplasma detector, which aims to solve the problems existing in the prior art.

[0004] This application provides a sealed mycoplasma detector. The detector includes an equipment area and a detection area. The detection area has a detection chamber with an opening on the top surface. A cover plate is hinged to the opening of the detection chamber. A sealing strip is fixed to the bottom of the cover plate near the edge. A magnet is installed inside the sealing strip. A groove is provided on the top edge of the detection chamber corresponding to the sealing strip. An electromagnet is installed inside the groove.

[0005] The testing chamber contains a testing frame that holds the incubation plate. Slides are provided on both sides of the testing frame, with one end of the testing frame corresponding to a slide closed and the other end open. A push plate is slidably connected to the slide, and a return spring is installed between the push plate and the closed end of the testing frame.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1The diagram shows a sealed mycoplasma detector. The detector 1 has a housing with a left-right distributed equipment area and a detection area. The equipment area housing contains a control component and a power supply component. The control component includes existing technologies such as a main controller or central processing unit. The power supply component includes existing technologies such as a battery and a power module and voltage module for voltage division. A display screen 2 is mounted on the top surface of the equipment area housing to display detection-related information.

[0019] The detection area is provided with a detection chamber 3 with an opening on the top surface. A cover plate 4 is hinged to the opening of the detection chamber 3. In this embodiment, a hinge 5 is provided on the rear side of the cover plate 4, which can open or close the cover plate 4.

[0020] like Figure 2 and Figure 3 As shown, a sealing strip 6 is fixed to the bottom of the cover plate 4 near its edge. The sealing strip 6 has a circular cross-section receiving cavity 7 with internal threads. The magnetized body 8 is cylindrical and has external threads. The length of the magnetized body 8 is less than the depth of the receiving cavity 7, and the magnetized body 8 is installed inside the receiving cavity 7 via threads. The magnetized body 8 is made of a magnetically conductive material, typically iron. The surface of the magnetized body 8 has a slotted or Phillips head that can be used with a screwdriver. During use, the magnetized body 8 is flush with the surface of the sealing plug. When the service life is long or the sealing strip 6 ages and shrinks, the magnetized body 8 can be rotated with a screwdriver to lower its height, ensuring that the surface of the magnetized body 8 remains flush with the surface of the sealing strip 6.

[0021] like Figure 4 As shown, the top edge of the detection chamber 3 has a groove 9 corresponding to the sealing strip 6, and an electromagnet is installed in the groove 9. When the electromagnet is energized, it generates magnetic force, which attracts the magnetized body 8 on the cover plate 4, making the cover plate 4 fit tightly against the detection chamber 3, thereby enhancing the sealing performance between the cover plate 4 and the detection chamber 3.

[0022] The detection chamber 3 is equipped with a detection frame 11 that fixes the incubation plate 10, which is a prior art material. Slide grooves 12 are provided on the left and right sides of the detection frame 11. The rear end of the detection frame 11 is closed, and the front end is open, with the open front end used to slide into the incubation plate 10. A push plate 13 is slidably connected to the slide groove 12. A return spring 14 is installed between the push plate 13 and the closed end (rear end) of the detection frame 11. Contacts 15 are installed opposite each other on the push plate 13 and the closed end (rear end) of the detection frame 11. Both the push plate 13 and the closed end (rear end) of the detection frame 11 have two contacts distributed left and right. The two contacts 15 on the push plate 13 are electrically connected to each other via a wire 16. One contact 15 on the detection frame 11 is electrically connected to a battery via a wire 16, and the other contact 15 is electrically connected to the electromagnet via a wire 16.

[0023] The above structure forms the switch for the electromagnet power supply circuit. In the natural state of the return spring 14, the push plate 13 is spaced from the closed end (rear end) of the detection frame 11, the contact 15 is not in contact, the electromagnet power supply circuit is open, and the electromagnet is not energized and does not generate magnetic force. When the incubation plate 10 is pushed in, the incubation plate 10 presses the push plate 13 against the closed end (rear end) of the detection frame 11, causing the push plate 13 to contact the contact 15 on the detection frame 11. The power supply circuit is closed, and the electromagnet is energized to generate magnetic force. After the electromagnet generates magnetic force, the cover plate 4 is closed, and the magnet makes the cover plate 4 fit tightly against the detection chamber 3, enhancing the seal.

[0024] After the test is completed, you can choose to first power off the instrument and then open the cover 4, or you can choose to open the cover 4 directly by hand to overcome the magnetic force.

[0025] The open end (front end) of the testing frame 11 is equipped with a baffle 17 via a self-locking hinge. The baffle 17 rotates 90 degrees to self-lock and is perpendicular to the slide 12. At this time, it can limit the incubation plate 10 and the push plate 13, ensuring that the push plate 13 and the contact point 15 on the testing frame 11 remain in contact.

[0026] Preferably, there are two return springs 14, which are distributed on both sides of the push plate 13 to prevent a single return spring 14 from generating a torsional force on the push plate 13 when it is stretched or retracted.

[0027] The detection rack 11 is positioned above the light source. Light can pass through the detection holes on the incubation plate 10, and the color change of the reagent in the sample can be detected by a color sensor, thereby obtaining the detection result for mycoplasma. This part is existing technology.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
