Description

Technical Field

[0001] The utility model belongs to the technical field of probiotic detection, and particularly relates to a probiotic fermentation detection device. Background Art

[0002] Probiotics are active microorganisms that benefit the host by colonizing the human body and altering the microbial composition of specific parts of the host. In recent years, with increasing environmental protection requirements and restrictions on antibiotic use, a new generation of probiotic products based on microbial ecosystems has rapidly developed, forming a substantial industry. Probiotic fermentation involves the conversion of probiotics into products needed by humans through specific metabolic pathways under suitable conditions. To ensure the effectiveness of probiotic fermentation, regular testing and adjustments based on the test results are necessary.

[0003] The existing probiotic fermentation detection device uses a rubber-tipped dropper to extract the fermented culture solution. However, when the dropper is placed flat or upside down, the solution in the tube is prone to backflow, causing solution contamination or solution corrosion of the rubber cap, which not only affects the service life of the rubber-tipped dropper and subsequent extraction effect, but also increases the detection cost. Utility Model Content

[0004] The purpose of the utility model is to provide a probiotic fermentation detection device, which, by pressing the sliding rod, can make the vent holes inside the rubber head continuously open and close in a cycle while the rubber head contracts to absorb liquid, thereby preventing the solution from flowing back into the rubber head when it is placed flat or upside down, avoiding solution corrosion of the rubber head or solution contamination, extending its service life, and thus saving detection costs.

[0005] The technical solutions adopted by this utility model are as follows:

[0006] A probiotic fermentation detection device includes a rubber head and a straw, wherein the inner wall of the rubber head is fixedly connected to a pipe mouth plug, the interior of the rubber head and above the pipe mouth plug is symmetrically fixedly connected to a connecting rod, the interior of the pipe mouth plug is symmetrically penetrated with an air hole for the connecting rod to pass through, the bottom of the connecting rod and below the pipe mouth plug is fixedly connected to a blocking column, the blocking column is movably connected to the air hole, the outer wall of the straw is symmetrically fixedly connected to a support rod, the support rod is elastically connected to a sliding rod through a spring column, and the rubber head is fixedly connected to the sliding rod through a pressure plate on the top.

[0007] The top of the support rod is symmetrically fixedly connected with a support plate.

[0008] The rubber head is plugged and engaged with the straw through a pipe mouth plug.

[0009] A sliding groove for sliding connection of the sliding rod is provided through the middle of the support plate.

[0010] The technical effect achieved by the utility model is that by pressing the sliding rod, the vent holes inside the rubber head are continuously opened and closed in a cycle while the rubber head contracts to absorb liquid, which can prevent the solution from flowing back into the rubber head when it is placed flat or upside down, avoiding solution corrosion of the rubber head or solution contamination, extending its service life, and thus saving detection costs.

[0016] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0017] like Figure 1-3 As shown, a probiotic fermentation detection device includes a rubber head 1 and a straw 101. The outer wall of the straw 101 is symmetrically fixedly connected to a support rod 111, and the top of the support rod 111 is symmetrically fixedly connected to a support plate 103. The support rod 111 is elastically connected to the sliding rod 102 through a spring column 105. A sliding groove 106 for sliding connection of the sliding rod 102 is opened in the middle of the support plate 103. The rubber head 1 is fixedly connected to the sliding rod 102 through the pressure plate 104 on the top.

[0018] According to the above structure, pressing the sliding rod 102 drives the pressure plate 104 to squeeze the rubber head 1, and the sliding rod 102 slides in the sliding groove 106 on the support plate 103, and the spring column 105 contracts at the same time. When the sliding rod 102 is released, the rebound of the spring column 105 causes the pressure plate 104 to drive the rubber head 1 to restore, and the support rod 111 supports the support plate 103 and the spring column 105.

[0019] Refer to the attached Figure 1-3 The inner wall of the rubber head 1 is fixedly connected with a pipe mouth plug 108, and the rubber head 1 is engaged and plugged with the straw 101 through the pipe mouth plug 108. A connecting rod 107 is symmetrically fixedly connected inside the rubber head 1 and above the pipe mouth plug 108. A vent hole 109 for the connecting rod 107 to pass through is symmetrically opened inside the pipe mouth plug 108. A blocking column 110 is fixedly connected to the bottom of the connecting rod 107 and below the pipe mouth plug 108. The blocking column 110 is movably plugged into the vent hole 109.

[0020] According to the above structure, when the rubber head 1 is squeezed and the connecting rod 107 moves downward, the connecting rod 107 drives the blocking column 110 to disengage from the vent 109, and the vent 109 opens to expel air. When the rubber head 1 rebounds and restores, it drives the connecting rod 107 to rise, so that the blocking column 110 is re-embedded in the vent 109, and the vent 109 is closed after the air is inhaled. The entire pipe mouth plug 108 is in a closed state, preventing the solution from flowing into the interior of the rubber head 1; the utility model presses the sliding rod 102 to achieve the continuous circulation of the vent 109 inside the rubber head 1 while the rubber head 1 contracts to absorb the liquid, which can prevent the solution from flowing back into the rubber head 1 when it is placed flat or inverted, thereby avoiding the solution corroding the rubber head 1 or the solution being contaminated, extending its service life, and thus saving the cost of detection.

[0021] The working principle of the present invention is as follows: pressing the sliding rod 102 drives the pressure plate 104 to squeeze the rubber head 1, the sliding rod 102 slides in the sliding groove 106 on the support plate 103, and the spring column 105 contracts at the same time, and the sliding rod 102 is released. The rebound of the spring column 105 causes the pressure plate 104 to drive the rubber head 1 to restore, and the support rod 111 supports the support plate 103 and the spring column 105. When the rubber head 1 is squeezed, the connecting rod 107 moves downward, and the connecting rod 107 drives the blocking column 110 to disengage from the vent 109, and the vent 109 opens to spit out air. When the rubber head 1 rebounds and restores, it drives the connecting rod 107 to rise, so that the blocking column 110 is re-embedded in the vent 109, and the vent 109 is closed after inhaling air. The entire pipe mouth plug 108 is in a closed state to prevent the solution from flowing into the inside of the rubber head 1.

[0022] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
