A circulating deodorizing device for a urination and defecation care machine

Abstract

This application discloses a circulating deodorization device for a urination and defecation care machine. The air from the negative pressure source fan is routed through a hose connector assembly back to the hose assembly, and then delivered to the urinal. Once the urinal is worn, it forms a relatively enclosed chamber with the body. Air enters the hose assembly from the wearable part, passes through the exhaust port of the wastewater tank, and then enters the deodorization module for continuous filtration of odorous gases. The air then enters the water vapor filtration module for moisture treatment, and finally passes through the air filtration module before returning to the negative pressure source fan inlet, forming a relatively closed circulating air path that prevents exchange with outside air. This fundamentally solves the problem of exhaust vents polluting indoor air, preventing gas exchange with the outside, deodorizing the internal circulating air, effectively preventing odor leakage, and ensuring deodorization effectiveness.

Description

Technical Field

[0001] This utility model relates to the field of nursing robot technology, and in particular to a circulating deodorization device for a urination and defecation care machine. Background Technology

[0002] There are many deodorization solutions on the market for toilet care robots. While they all have some deodorization effect, the actual results are not ideal. The current deodorization solutions are inefficient for two main reasons: 1. Deodorization is only performed on the odor circuit outside the wastewater tank. The odor from inside the tank is drawn into the ozone module by a vacuum motor. However, this method may leave a large amount of odor residue inside the tank and in the pipes, failing to effectively prevent the spread of odor. 2. Most methods use physical adsorption to absorb odor. However, during adsorption, a large amount of odor quickly fills the adsorption capacity of the consumable, requiring frequent replacement, resulting in a short lifespan and high consumption. Furthermore, this method cannot guarantee that the odor in the deodorization module is treated in a timely manner, allowing odor to still diffuse into the air from the ozone module's outlet. Utility Model Content

[0003] In view of the shortcomings or deficiencies of the prior art, the technical problem to be solved by this utility model is to provide a circulating deodorization device for a urination and defecation care machine.

[0004] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0005] A circulating deodorization device for a toilet care machine includes:

[0006] The upper cover is provided with an air inlet and an air outlet, both of which are connected to the sewage tank.

[0007] The base, the upper cover is detachably connected to the base, and the bottom of the base is provided with a base air outlet;

[0008] An ozone generator, wherein the ozone generator is installed inside the base;

[0009] The fan is installed inside the base;

[0010] A one-way valve is disposed within the base.

[0011] Furthermore, the air inlet of the upper cover is connected to the air outlet of the sewage tank through a sealing ring, and the air outlet of the upper cover is connected to the air inlet of the sewage tank through a sealing ring.

[0012] Furthermore, the base is provided with a baffle, and the baffle has a ventilation opening in the middle, which divides the interior of the base into a first accommodating space and a second accommodating space.

[0013] Furthermore, the one-way valve is disposed between the first and second accommodating spaces and on one side of the vent.

[0014] Furthermore, a mounting groove is provided on one side of the baffle, and the rotating shaft of the one-way valve is installed in the mounting groove.

[0015] Furthermore, the air outlet of the base is located at the bottom of the first accommodating space.

[0016] Furthermore, the second accommodating space is provided with a first fixing slot, and the ozone generator is installed in the first fixing slot.

[0017] Furthermore, a second fixing groove is provided on one side of the first fixing groove, and the fan is installed in the second fixing groove.

[0018] Furthermore, the air outlet of the fan is aligned with the air outlet of the upper cover.

[0019] Furthermore, the upper cover air outlet is provided with a snap-fit ​​groove, and the air outlet of the fan snaps into the snap-fit ​​groove.

[0020] Compared with the prior art, this application has the following technical effects:

[0021] (1) In this application, during the deodorization operation, the ozone generator is powered on to produce ozone gas, and the fan next to it starts working, sending the generated ozone into the sewage tank through the air outlet of the top cover. At this time, the ozone reacts chemically with the odor molecules in the tank, decomposing them. Simultaneously, the one-way vents of the one-way valves open, and the gas in the sewage tank returns to the fan through the sewage tank air outlet, the air inlet of the top cover, and the baffle vent. Then, it carries the ozone generated by the ozone generator back into the sewage tank through the air outlet of the top cover and the air inlet of the sewage tank, realizing the cyclical decomposition of the odor in the sewage tank. Through the above method, the odor in the sewage tank can be quickly and effectively decomposed, thereby achieving the purpose of eliminating odor, and further preventing the spread of odor, improving the user experience.

[0022] (2) In this application, only ozone generated by energizing the ozone generator is needed to directly oxidize and decompose the odor in the sewage tank into harmless or low-harm substances such as water, carbon dioxide, and other simple inorganic substances. The operation is simple and convenient. Moreover, the ozone generator used in this application is inexpensive and has a long service life, which can meet the requirement of long-term use without replacement, avoiding a large amount of consumables and thus saving costs.
