Description

Technical Field

[0001] The present invention relates to the technical field of purification bottle cleaning, and specifically to an integrated cleaning device for purification bottles.

Background Art

[0002] The purification bottle is a sample bottle, also called a sampling bottle, sterile bottle, cleaning bottle, filtration bottle, filtered purification bottle, sample bottle, filter bottle, etc., and is an essential item for pollution inspection. Usually, the usage amount of particle counters is large, and the dedicated sample bottle body for particle counters is created using a series of process flows such as high-precision ultrasonic cleaning machine cleaning, thousand-stage clean air shower, and drying and sealing. It is a dedicated sampling container for particle counters to conduct liquid pollution degree tests. Although the cleaning process of this purification bottle is essential, the related cleaning devices have the following drawbacks in actual use: 1. Some of the main cleaning parts of the purification bottle are the bottle body, cap, and bottle body mat. However, during cleaning, they are often cleaned separately, and there is a lack of a cleaning device that can clean the bottle body, cap, and bottle body mat integrally. It is necessary to clean step by step and use different cleaning devices assistively, resulting in increased costs and low cleaning efficiency. 2. Next, when cleaning the bottle body cap of the purification bottle, it is usually cleaned upside down, and the cleaning water is sprayed upward. The cleaning of the bottle body and cap is in its inner wall area. The cleaning ensures cleanliness and is often in the bottle mouth area. However, during cleaning, it is necessary to always replace and clean new purification bottles. During this process, there is a certain idle period, and it is easy for the cleaning water to be sprayed, and it is impossible to realize the on and off operations that can be opened during cleaning and closed when taken away.

[0015] The technical proposals in the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention.

[0016] As shown in Figures 1-7, the present invention is a purification bottle integrated cleaning device, comprising a cleaning tank 1, a cleaning tub 2, a cleaning structure 3, and a pump 4. The cleaning tub 2 is provided above the inside of the cleaning tank 1, and the cleaning structure 3 is provided inside the cleaning tank 1 on one side of the cleaning tub 2. The pump 4 is fixed to the outer wall of the cleaning tank 1. A large amount of cleaning water is stored in the cleaning tank 1, but the water level does not exceed the cleaning structure 3. The cleaning water is periodically replaced or filtered. The cleaning structure 3 is used to clean the bottle body and cap of the purified bottle, and the cleaning water is extracted from the cleaning tank 1 via the pump 4 and input into the cleaning structure 3 for use.

[0017] A grill 201 is fixed inside the washing tank 2, and the washing tank 2 is equipped with a grill 201 for washing the bottle body mat. The bottle body mat is placed on the grill 201, and since the water level does not exceed the bottle body mat, ultrasonic cleaning can be performed.

[0018] The cleaning structure 3 includes three cleaning tubes 301, and each cleaning tube 301 is provided with three bottle body cleaning units 302 and three cap cleaning units 303. One cleaning tube 301 can be used to clean three bottle bodies and three caps simultaneously.

[0019] The bottle body cleaning unit 302 includes a first ring groove 3021 fixed to the cleaning tube 301 and a first column casing 3022 disposed within the first ring groove 3; an L-shaped tube 3023 having an annular array distribution is fixedly penetrated through the outer periphery of the first column casing 3022, and a first shaft rod 3025 is further inserted and fixed within the first column casing 3022. A first rubber stopper 3026 is fixed to the bottom of the first shaft rod 3025. When cleaning the inside of the bottle body, hang it upside down on the bottle body cleaning unit 302. The upper part of the first shaft rod 3025 and the first column casing is inserted into the bottle body. The bottle mouth is located within the first ring groove 3021 and disposed between the L-shaped tubes 3023. The outside of the bottle mouth is cleaned using the through holes on the L-shaped tubes 3023. The first rubber stopper 3026 is used to block the bottom of the first column casing 3022.

[0020] The cap cleaning unit 303 includes a second ring groove fixed to the cleaning tube 301 and a second column casing 3032 disposed within the second ring groove 3031. A second shaft rod 3034 is inserted into the inside of the second column casing 3032, and a second rubber stopper 3035 is fixed to the bottom of the second shaft rod 3034. When cleaning the cap, hang it on the second shaft rod 3034 and the second column casing 3032 and position it inside the second ring groove 3031. Lower the second shaft rod 3034, move the second rubber stopper 303 downwards to open the bottom of the second column casing 3032 and connect it to the cleaning tube 301. Inject cleaning water into the cap through the second through hole 3033 for cleaning and use.

[0021] Two support columns 101 are fixed inside the cleaning tank 1, and the bottom of the cleaning tank 2 is fixed to the support columns 101. The support columns 101 are for auxiliary fixing of the cleaning tank 2.

[0022] In the cleaning tank 2, three equally spaced ultrasonic transducers 202 are fixed to the surface adjacent to the pump 4, and a reflux pipe 203 is fixed through the cleaning tank 2 on one side away from the cleaning structure 3, with the bottom end of the reflux pipe 203 facing into the cleaning tank 1. The ultrasonic transducer 202 is used in combination with an external ultrasonic generator to ultrasonically clean the bottle mat in the cleaning tank 1, and the cleaning water in the cleaning tank 2 flows into the cleaning tank 1 via a reflux pipe.

[0023] In the first column casing 3022, the portion lower than the first ring groove 3021 extends through into the cleaning pipe 301, and the first rubber stopper 3026 is also located inside the cleaning pipe 301. The L-shaped pipe 3023 is located inside the first ring groove 3021, and the first seal head 3027 is fixed to the upper end of the first shaft rod 3025. The first seal head 3027 is located above the first column casing 3022 and is larger than the inner diameter of the first column casing 3022, and the height of the first shaft rod 3025 is greater than the height of the first column casing 3022.

[0024] A first through-hole 3024 is provided on the side of the first column casing 3022 located above the L-shaped pipe 3023, and the first through-hole 3024 is also provided on one side of the L-shaped pipe 3023 facing the first column casing 3022. The bottom of the first column casing 3022 enters the washing pipe 301, and if the water pressure in the washing pipe 301 is sufficient, the first rubber stopper 3026 is forced into contact with the bottom of the first column casing 3022, closing the bottom of the first column casing 3022. During washing, the bottle is hung upside down outside the first column casing 3022, and the bottom of the bottle contacts the first seal head 3027, creating downward pressure and moving the first shaft rod 3025 and the first rubber stopper 3026 downwards. At this time, the first rubber stopper 3026 does not close the first column casing 3022, the bottom of the first column casing 3022 is in communication with the inside of the washing pipe 301, washing water enters the first column casing 3022 and the L-shaped pipe 3023, and the washing water ejected through the first through-hole 3024 on the surface of the first column casing 3022 washes the inner wall of the bottle, and the washing water ejected through the first through-hole 3024 on the surface of the L-shaped pipe 3023 washes the neck of the bottle. When cleaning is complete and the bottle body is removed, there is no external force acting on the first shaft rod 3025. At this time, the first rubber stopper 3026 is struck under the action of water pressure, forcibly moving the first rubber stopper 3026 upwards, once again sealing the bottom of the first column casing 3022, and preventing the spraying of excess cleaning water.

[0025] In the second column casing 3032, the portion lower than the second ring groove 3031 extends through into the cleaning pipe 301, and the second rubber stopper 3035 is also located inside the cleaning pipe 301. A second seal head 3036 is fixed to the upper end of the second shaft rod 3034, and the second seal head 3036 is located above the second column casing 3032 and is larger than the inner diameter of the second column casing 3032. The height of the second shaft rod 3033 is greater than the height of the second column casing 3032, and a second through hole 3033 is provided on the side of the portion of the second column casing 3032 located inside the second ring groove 3031. When cleaning the cap, the cap is inserted outside the second column casing 3032 and positioned in the second ring groove 3031. The cap is then pushed down, moving the second seal head 3036 and the second shaft rod 3034 downwards, thereby lowering the second rubber stopper 3035. This exposes the bottom of the second column casing 3032, connecting it to the cleaning pipe 301. Cleaning water is then introduced into the second column casing 3032 and ejected from the second through-hole 3033 to clean the cap. After cleaning, the cap is removed. At this time, there is no external force acting on the second shaft rod 3034, and the second rubber stopper 3035 moves upward under the water pressure, continuing to seal the second column casing 3032.

[0026] A suction pipe 401 is fixed to the suction end of the pump 4, and one end of the suction pipe 401 away from the pump 4 extends through into the washing tank 1. A water supply pipe 402 is fixed to the outlet end of the pump 4, and one end of the water supply pipe 402 away from the pump 4 extends through into the washing tank 1. A guide pipe 4021 is fixed to the other end of the water supply pipe 402, with the top of the guide pipe 4021 pointing upwards towards the washing tank 2. Three branch pipes 4022 are further fixed through the circumferential portion of the water supply pipe 402 located inside the washing tank 1, and each of the three branch pipes 4022 is connected through to the ends of the three washing pipes 301. Pump 4 extracts cleaning water from cleaning tank 1 via suction pipe 401, outputs it via supply pipe 402, inputs it into cleaning pipe 301 via three branch pipes 4022, and also transports it above cleaning tank 2 via guide pipe 4021, enters cleaning tank 2, injects cleaning water into cleaning tank 2, and discharges it via return pipe to achieve circulation.

[0027] A link 304 is fixedly connected between two adjacent cleaning pipes 301, and the two outermost cleaning pipes 301 are further fixedly connected to the inner wall of the cleaning tank 1 via the link 304. The cleaning pipes 301 are fixed at both ends by the link 304 and fixed to the inner wall of the cleaning box 1 by the link 304.

[0028] The specific operating principle of this invention is as follows: First, a large amount of cleaning water is stored in the cleaning tank 1, but the water level does not exceed the cleaning structure 3. The pump 4 extracts the cleaning water from the cleaning tank 1 through the suction pipe 401, outputs it through the supply pipe 402, inputs it into the cleaning pipe 301 through three branch pipes 4022, and also transports some of it to the top of the cleaning tank 2 through the guide pipe 4021, enters the cleaning tank 2, injects the cleaning water into the cleaning tank 2, places the bottle mat on the grill 201, ensures that the water level does not pass over the bottle mat, and uses the ultrasonic transducer 202 in combination with an external ultrasonic generator to perform ultrasonic cleaning to achieve cleaning of the bottle mat in the cleaning tank 1.

[0029] When cleaning the bottle body of the purification bottle, the bottle body is placed upside down outside the first column casing 3022, the bottom of the bottle is brought into contact with the first seal head 3027, and pressed down, causing the shaft 3025 and rubber stopper 3026 to move downward. At this time, the rubber stopper 3026 does not seal the first column casing 3022, the bottom of the first column casing 3022 is in communication with the inside of the cleaning pipe 301, and the cleaning water enters the first column casing 3022 and the L-shaped pipe 3023, and is ejected through the first through-hole 3024. The cleaning water ejected through the first through-hole 3024 on the surface of the first column casing 3022 cleans the inner wall of the bottle, and the cleaning water ejected through the first through-hole 3024 on the surface of the L-shaped pipe 3023 cleans the bottle mouth. After the cleaning is complete, when purifying the bottle body, there is no external force acting on the first shaft rod 3025. At this time, the first rubber stopper 3026 is struck under the action of water pressure, forcibly moving the first rubber stopper 3026 upwards, closing the bottom of the first column casing 3022 again, and preventing the spraying of excess cleaning water.

[0030] On the other hand, when cleaning the cap, the cap is inserted outside the second column casing and positioned in the second ring groove 3031, the cap is pushed down, the second seal head 3036 and the second shaft rod 3034 move downward, the second rubber stopper 3035 is lowered, the bottom of the exposed second column casing is connected to the cleaning pipe 301, cleaning water is introduced into the second column casing and ejected from the second through hole 3033 to clean the cap, and the cleaned cap is removed. At this time, there is no external force acting on the second shaft rod 3034, the second rubber stopper 3035 moves upward under the action of water pressure, continues to seal the second column casing, and subsequent cleaning is performed.

[0031] Furthermore, the outer circumference of the first column casing 3022 and the second column casing 3032 is equipped with a large number of through-holes. To fill the inner top of the washing cap and the inner top of the bottle, half of the through-holes in the upper region of the first column casing 3022 and the second column casing 3032 are oblique holes (like the needle hole of a syringe), distributed in a staggered pattern and inclined toward the inner top of the bottle. After filling with water, the water directly impacts the inner top of the bottle, washing the inner surface of the bottle. Moreover, a large amount of fine water flow impacts the inner wall of the bottle cap, causing a large amount of irregular sputtering inside, allowing for more effective cleaning. The cap allows the bottle to be rotated during cleaning. To ensure thorough cleaning, the retaining cap at the bottom of the bottle can be cleaned by slightly tilting the bottle to allow the water flow to impact the original retaining cap.

[0032] The above are merely preferred embodiments of the present invention and do not limit the present invention. Any modifications, equivalent substitutions, or improvements made by modifying the technical methods described in each of the above embodiments, or by substituting some of the technical features therein with equivalent ones, are also covered within the scope of the present invention.
