TECHNICAL FIELD

[0001] The utility model relates to the technical field of humidification tank, more particularly to a humidification tank. BACKGROUND

[0002] The humidification tank is an instrument used in cooperation with a breathing machine (or other breathing treatment equipment with the same function), which stores water inside, is usually connected between the breathing machine and a gas delivery pipeline, and is used for humidifying the passing gas; if the humidification tank is heated, the passing gas can also be heated. When water is added to the humidification tank, the amount of added water must be ensured not to exceed a certain height, otherwise the water will overflow into the gas delivery pipeline, causing the patient to cough and choke, increasing the probability of related pneumonia in the patient, and possibly aggravating the patient's condition, and even causing the patient to suffocate in critical cases. In order to solve the above problems, some existing humidification tanks have a float that can move up and down along the height direction, which moves up to block the water outlet pipe to limit water inflow when the tank is full, and automatically replenishes water when the water is insufficient. Specifically:

[0003] As shown in Figure 1 The inner top wall of the humidification tank body 1 is vertically provided with a guide pipe 102, the guide pipe 102 is provided with a water outlet pipe 103, one end of the water outlet pipe 103 is a water outlet, and the other end of the water outlet pipe 103 is used to connect a water inlet pipe 5 for supplying water to the tank cavity 101. When the float 3 floats up, the silicone gasket 4 at the top of the float 3 blocks the water outlet of the water outlet pipe 103.

[0004] However, since the upper part of the float 3 is fitted into the guide pipe 102 with a gap, there is a certain gap between the upper part of the float 3 and the wall of the guide pipe 102, which cannot guarantee that the float 3 will float vertically, and there is an incomplete sealing condition between the silicone gasket 4 and the water outlet of the water outlet pipe 103 after abutting, which makes the sealing effect poor and causes water leakage. At the same time, the end face of the bottom end of the float 3 and the inner bottom wall of the humidification tank base 2 are both flat, and there is an adsorption force between the float 3 and the base 2 after abutting, which hinders the float 3 from floating up.

[0005] Therefore, a new scheme is needed to solve the above problems. UTILITY MODEL CONTENTS

[0028] 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.

[0029] Example: A humidification tank, such as Figures 2-5As shown, including the tank body 1, base 2 and float 3, the tank body 1 has a cavity 101, the tank body 1 bottom opening and sealing connection base 2 to seal the cavity 101 bottom surface at the same time; the inner top wall of the tank body 1 is vertically provided with a guide pipe 102, the guide pipe 102 is provided with a water outlet pipe 103, one end of the water outlet pipe 103 is a water outlet, the other end of the water outlet pipe 103 is used to connect the water injection pipe 5 to supply water to the tank body 1. The float 3 is located in the cavity 101 of the tank body 1, the upper part of the float 3 is gap fitted in the guide pipe 102, so that the float 3 can move up and down along the guide pipe 102 reciprocating with the change of water level in the cavity 101 of the tank body 1.

[0030] Further, as shown in Figure 3 and Figure 4 , the top end of the float 3 is provided with a silica gel gasket 4 for blocking the end of the water outlet pipe 103 when the float 3 moves up, the silica gel gasket 4 is downwardly concave, that is, the silica gel gasket 4 is downwardly concave and arc-shaped. When the water level in the tank body 1 is sufficient to make the float 3 float up, the end of the water outlet pipe 103 will abut against the silica gel gasket 4 and be blocked, preventing water from entering from the outside; when the water level in the tank body 1 decreases, the float 3 moves down along the guide pipe 102, so that the silica gel gasket 4 is separated from the end of the water outlet pipe 103, so that the water outlet pipe 103 can normally outlet water for water replenishment. By setting the silica gel gasket 4 downwardly concave, the contact area between the silica gel gasket 4 and the end of the water outlet pipe 103 is increased, avoiding the situation that the silica gel gasket 4 cannot completely block the end of the water outlet pipe 103 when the float 3 moves up along the guide pipe 102. At the same time, the hardness of the silica gel gasket 4 is 20, so as to improve the softness and resilience of the silica gel gasket 4, so that the silica gel gasket 4 can better fit the end of the water outlet pipe 103 and block the end of the water outlet pipe 103.

[0031] As a preferred, the silica gel gasket 4 is bonded to the top end of the float 3 by glue, compared with the existing ultrasonic bonding method, the connection strength is higher, the connection stability between the silica gel gasket 4 and the float 3 is better, and the durability of the humidification tank is improved.

[0032] As shown in Figure 3 and Figure 5 , the end face of the bottom end of the float 3 is downwardly convex, the float 3 is formed between the bottom end of the float 3 and the base 2, the contact area between the float 3 and the base 2 is reduced to reduce the adsorption force between the float 3 and the base 2, so that the water in the cavity 101 can flow into the gap between the float 3 and the base 2 to float the float 3 up, avoiding the float 3 from being blocked from floating up.

[0033] Further, as shown in Figure 5 and Figure 6 , the bottom end of the float 3 is uniformly provided with a plurality of downward convex protrusions 301, the end face of the protrusion 301 is spherical. By setting the protrusion 301, the bottom end of the float 3 is lifted, so that the water in the cavity 101 can flow smoothly into the gap between the float 3 and the base 2 to float the float 3 up.

[0034] Further, as shown in Figure 2 The water injection pipe 5 is provided with a dropper 6, which is transparent and used for storing and dripping water. The installation of the dropper 6 makes the water injection visualized, and facilitates the observation of whether there is water in the water injection pipe 5 and the water flow speed. Meanwhile, the dropper 6 can be used to know whether the outlet pipe 103 is blocked. During use, the water can be smoothly injected into the water injection pipe 5 by pressing the dropper 6.

[0035] Further, as shown in Figure 2 The water injection pipe 5 is provided with a flow regulator 7, which is a prior art. For example, Chinese patents CN202321943481.0 and CN202320290164.7 have disclosed the flow regulator 7. The installation of the flow regulator 7 facilitates the adjustment of the water flow in the water injection pipe 5 and the water stop at any time.

[0036] As a preferred embodiment, the water injection pipe 5 is a hollow tubular structure with bending resistance, which is made of silica gel. The increase of the hardness and resilience of the water injection pipe 5 makes it have better bending resistance, prevents bending, and improves the durability of the water injection pipe 5.

[0037] The above only describes the preferred embodiments of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solutions falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that, for ordinary skilled persons in the technical field, some improvements and decorations without departing from the principles of the present application shall also be considered as the protection scope of the present application.
