[0002] Humidification bottles are a common medical product, mainly used to connect to oxygen supply devices to humidify and deliver oxygen to patients. Driven by population aging and the rising incidence of chronic respiratory diseases, the global market for humidification bottles is growing steadily.

[0003] In the production of humidification bottles, sealing the bottle is the most critical step. This step involves attaching the cap to the bottle body, creating a sealed space inside for filling the humidification solution. The sealing process has varying degrees of impact on the chemical properties, sterility, pressure resistance, airtightness, and leakage prevention of the humidification solution. Currently, the production of humidification bottles mainly relies on manual methods, where the cap is screwed onto the bottle body. This method suffers from low production efficiency, low product qualification rate, and high production costs.

[0004] The patent application number "CN202223339205.1" discloses an "automatic assembly device for the cap of an oxygen humidification bottle". Although it realizes the automatic assembly of the humidification bottle, the equipment is large in scale, requires sufficient production space for installation, and the equipment cost is too high.

[0028] The present invention will now be further described with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figure 1 — Figure 3 As shown, the Type I humidification bottle described in this embodiment includes a bottle body 100 and a bottle cap 200. The bottle body 100 is provided with a first threaded portion 102 (external thread), and the bottle cap 200 is provided with a second threaded portion 201 (internal thread) that mates with the first threaded portion 102. A connector mounting portion 203 is also provided at the center of the upper part of the bottle cap 200. A first connector 204 is provided on the side wall of the connector mounting portion 203, and a second connector 205 is provided on the top of the connector mounting portion 203. A protruding baffle 202 is also provided on the bottle cap 200. In this embodiment, the baffle 202 is evenly distributed in four places on the bottle cap 200. The bottle body 100 also has a hexagonal outer shell 101.

[0031] like Figure 4 — Figure 8 As shown, a type I humidification bottle cap screwing device includes a bottle body chuck 11 for accommodating a bottle body 100 and a cap sleeve 22 for accommodating a cap 200. The bottle body chuck 11 has an inner hole that matches the hexagonal outer shell 101. When the bottle body chuck 11 rotates, the bottle body 100 rotates accordingly. The bottom of the cap sleeve 22 is provided with a protrusion 24 that cooperates with a baffle 202 to tighten the cap 200. The bottle body chuck 11 is connected to a motor 16 that drives its rotation, and the cap sleeve 22 is connected to a second telescopic rod 21 that drives its up and down movement. In use, first manually screw the cap 200 onto the bottle body 100, then place the humidification bottle into the bottle body chuck 11. Next, the cap sleeve 22 moves down until the lower end of the protrusion 24 is below the upper end of the baffle 202 and abuts against the upper part of the cap 200. At this point, the bottle body chuck 11 drives the bottle body 100 to rotate, and the cap 200 cannot rotate due to the action of the protrusion 24. As the bottle body 100 rotates, the cap 200 gradually tightens and moves down, at which point the second telescopic rod 21 drives the cap sleeve 22 to move down accordingly. This tightens the cap 200 onto the bottle body 100.

[0032] In order to shorten the stroke of the second telescopic rod 21 and the bottle cap sleeve 22, the initial position of the bottle cap sleeve 22 (the position when the humidification bottle is put in or taken out) needs to be moved down as much as possible, while not affecting the insertion and removal of the humidification bottle. For this purpose, a clearance groove 23 is provided on the bottle cap sleeve 22 to facilitate the passage of the first connector 204.

[0033] The device also includes a fixed plate 3, on which a limit switch 31 is provided to detect the downward movement distance of the bottle cap sleeve 22. A test part 25 is provided on the second telescopic rod 21 to cooperate with the limit switch 31. When the second telescopic rod 21 extends and retracts to drive the bottle cap 200 to move up and down, the test part 25 moves synchronously.

[0034] The limit switch 31 can be set as a non-contact switch. When producing a humidification bottle of a certain specification, the downward movement distance of the second telescopic rod 21 is preset and the distance between it and the part to be measured 25 is monitored in real time by the limit switch 31. If the distance meets the requirements, the motor 11 rotates and tightens the humidification bottle; if the distance does not meet the requirements, the equipment is prompted to malfunction and manual maintenance is required (in actual production, the main reason for this problem is that the lower end of the protrusion 24 is in contact with the upper end of the baffle 202 at the current placement angle of the bottle body 100 and cannot move down, resulting in the distance being too large and not meeting the requirements). The bottle body 100 needs to be manually changed to a different angle.

[0035] The limit switch 31 can be configured as a contact switch. When producing a humidification bottle of a certain specification, its installation position is pre-calculated. When the bottle cap sleeve 22 moves down until the lower end face of the protrusion 24 is lower than the upper end face of the baffle 202 (at which position the motor 11 can rotate to tighten the humidification bottle), the part to be tested 25 is pressed against the limit switch 31. The limit switch 31 sends a signal, and the motor 16 rotates. If the lower end face of the protrusion 24 abuts against the upper end face of the baffle 202, the part to be tested 25 will not be pressed against the limit switch 31 due to insufficient downward movement. In this case, the limit switch 31 will not send a signal, the motor 16 will not rotate, and manual maintenance will be required.

[0036] The bottle chuck 11 is fixed to the support plate 15 by bolts, and the shaft of the motor 16 passes through the support plate 15 and is connected to the bottle chuck 11. The cap sleeve 22 and the second telescopic rod 21 are also connected by bolts. Depending on the size of the humidification bottle, the bottle chuck 11 and cap sleeve 22 can be replaced.

[0037] The device also includes a base 1, which has a guide groove 13 for placing the tray 15, the motor 16, and the bottle chuck 11. A first telescopic rod 14 is provided in the guide groove 13 to drive the tray 15 to move back and forth. At this time, the bottle chuck 11 and the tray 15 are connected by bearings. When the bottle chuck 11 rotates under the drive of the motor 16, the tray 15 will not rotate with it.

[0038] The first telescopic rod 14 allows the tray 15 and the bottle chuck 11 to move back and forth. Moving forward facilitates the insertion of the humidification bottle into the bottle chuck 11, after which the bottle chuck 11 moves backward, and the bottle cap sleeve 22 moves downward for assembly. Without the first telescopic rod 14, the bottle cap sleeve 22 would need to be moved upward from its initial position to smoothly insert the humidification bottle into the bottle chuck 11, resulting in a larger stroke for the second telescopic rod 21.

[0039] The device also includes a top seat 2, on which a second telescopic rod 21 is mounted. The top seat 2, the base 1, and the fixed upright plate 3 are connected to each other to form a stable structure.

[0040] This device also includes a manual button and a foot switch to start the equipment. When in use, the operator can choose the starting method according to their preference, which reduces the labor intensity of the workers.

[0041] Currently, our factory produces two main sizes of Type I humidification bottles. During production, the appropriate bottle chuck 11 and cap sleeve 22 are selected based on the bottle size. A control knob is also installed on the base 1, with two positions (the corresponding telescopic rod movement distance, tightening force, and other parameters are pre-set for each position), corresponding to the two bottle sizes. Select the appropriate knob position based on the bottle size, and then operate the equipment using the manual button or foot switch. In actual production, our factory presets the tightening force for both types of humidification bottles as follows: 4.5 N / cm for small bottles and 5 N / cm for large bottles.

[0042] In this embodiment, both the first telescopic rod 14 and the second telescopic rod 21 are cylinders. In use, the bottle body 100 and the bottle cap 200 are first connected manually, and then the humidification bottle is placed into the bottle chuck 11. The equipment can be started to automatically tighten the humidification bottle, which improves the consistency of product quality and increases production efficiency.
